Storing container 1 is to insert the container in general refrigerator, and can be implemented as single box (or claiming a box) type or double box (or claiming two boxes) type.Single box (or a box) type can include a box body, and it has upper shed and covers the lid of this upper shed.The storage container (as shown in Figure 2) of that type that double boxes (two boxes) type can seal in the way of by with drawer-like, and include the box body accommodating unit 211 with open front and can be inserted into and extract out the box body 213 of this box body accommodating unit.This one exemplary embodiment shows that double cell type stores container 1, but is not limited thereto.Storage container according to the present invention can also be implemented as single-casing-type.
As in figure 2 it is shown, barometric control unit 100 preferably can be inserted into storage container 1 from the outside of box body accommodating unit 211.
Especially, barometric control unit 100 may be mounted to that on the upper plate 211a or side plate 211b of box body accommodating unit 211.Here, when this device is installed on side plate 211b, this device can be overlapping with box body 213 when box body 213 is inserted into.In the case, in this device can be inserted into upper plate 211a.Although not shown in, barometric control unit 100 also may be mounted on the rear surface of box body accommodating unit 211.
In barometric control unit 100, when the air pressure inside storing container 1 is reduced to less than preset air pressure, then the passage (through hole 103 in Fig. 3) for being introduced in storage container 1 by extraneous air can be opened, to improve air pressure inside, so that the air pressure inside storing container 1 keeps uniformly.

When the air pressure inside storing container is reduced to less than preset air pressure, the barometric control unit 100 worked as valve can be opened to allow extraneous air to introduce storage container 1, thus prevents the air pressure inside storing container 1 from falling below preset air pressure.So scalable air pressure inside, and it is possible to avoid the article corruption being stored in storage container in advance, be dried or similar state occurs.
With reference to Fig. 3, barometric control unit 100 comprises the steps that housing, has the through hole 103 running through the formation of this housing to allow to introduce extraneous air；Movable link 110, it is installed in this housing, and can be mobile (towards this through hole) forward and leave this through hole and move (such as can upwardly or downwardly move), in order to air pressure inside based on this storage container 1 and the level error (pressure reduction) of external pressure and selectively open and close this through hole 103；Supporting member 150, is fixed in this housing, and separates with this movable link 110；And elastic component 130, by regularly between this movable link 110 and this supporting member 150.
Barometric control unit 100 can work as valve, and this valve is driven under preset air pressure.Specifically, this barometric control unit 100 can be opened under conditions of less than preset air pressure, and is closed under conditions of higher than preset air pressure.Here, this preset air pressure can be determined by the coefficient of elasticity of regulation elastic component 130.
This housing can be in hollow tubular.This housing can have upper surface and open lower surface, and this upper surface is formed through through hole 103, and this lower surface is inserted in storage container 1 hermetically.This housing also can be formed tubular or square.
With continued reference to Fig. 3, the inside of this housing can be divided into the first inner space A, the second inner space B and the 3rd inner space C based on movable link 110 and supporting member 150.Here, the periphery of movable link 110 can be attached to the first contact site 105a of inner peripheral surface of housing.First inner space A and the second inner space B can change due to the bending of movable link 110.
Fig. 4 A, Fig. 4 B illustrate the border between the first inner space A and the second inner space B.When storing container 1 and being under suitable air pressure inside (see Fig. 4 A), movable link 110 can not be bent downwardly (or the deformation of up concave type ground), and thus can present a smooth border between the first inner space A and the second inner space B.But, when the air pressure inside storing container 1 is less than external pressure (see Fig. 4 B), movable link 110 can be bent downwardly, and presents the border of a bending between the first inner space A and the second inner space B.
This housing can include that cylindrical portion 105, cylindrical portion 105 are formed hollow round tubular.The inner peripheral surface of cylindrical portion 105 includes the first contact site 105a and the second contact site 105b, and movable link 110 is attached on this first contact site, and supporting member 150 is attached on this second contact site.
With reference to Fig. 3 and Fig. 5 A, Fig. 5 B, movable link 110 comprises the steps that open/close portion 111, in order to open and close through hole 103；Deformable part 113, in order to allow open/close portion 111 to move；And elastic component fixed part 115, in order to fix this elastic component 130.
As shown in Fig. 3 to Fig. 5 A and Fig. 5 B, open/close portion 111 can open and close through hole 103, and this through hole becomes air intake after this housing is connected to store container 1 hermetically, and extraneous air is introduced into via this air intake.Through hole 103 may be in response to the downward of open/close portion 111 and moves up and be opened and closed.Therefore, open/close portion 111 preferably can be formed by rubber, to close through hole 103 airtightly.
The deformable part 113 of movable link 111 can be implemented as the rubber parts of circle, and this rubber parts is attached on the inner peripheral surface of cylindrical shell.In the case of the periphery of deformable part 113 is fixed to this housing, this deformable part 113 may be in response to be moved up and down the moving up and down of open/close portion 111 of the central area of deformable part 113 formation.
As shown in Fig. 4 A, Fig. 4 B and Fig. 5 A, Fig. 5 B, moving up and down of open/close portion 111 can be realized by deformable part 113.Deformable part 113 can be formed by rubber such that it is able to up concave type ground deformation (being bent downwardly) also returns to original shape subsequently, and the periphery of deformable part 113 is fixedly attached on the first contact site 105a of this housing simultaneously.
Deformable part 113 can be identical with the cross section of housing (such as circular) plane in shape, and is made by having the predetermined elasticity coefficient rubber for deformation.Here, the predetermined elasticity coefficient of deformable part 113 can be depending on and is expected to store the air pressure kept in container.
With reference to Fig. 3 and Fig. 4 A, Fig. 4 B, deformable part 11 can include multiple pore 113a, and these pores run through deformable part 113 along the thickness direction of this deformable part and formed.Movable link 110 can be made up of rubber.
Seeing Fig. 4 A, Fig. 4 B and Fig. 5 A, Fig. 5 B, elastic component 130 can be fixed to the elastic component fixed part 115 being positioned on the central area of the lower surface of movable link 110.Elastic component 130 can have top and bottom, and this lower end can be supported to prevent it from moving up and down by supporting member 150, and this upper end deforms (or being bent downwardly) at movable link 110 up concave type and restores and be compressed and extended when downwardly and upwardly moving.Elastic component 130 can be the spring with predetermined elasticity coefficient.
Air pressure keeps condition to be the difference according to air pressure inside and the external pressure storing container 1 and is preset, and air pressure keeps condition the coefficient of elasticity of coefficient of elasticity based on deformable part 113 and elastic component 130 to determine.Especially, with reference to Fig. 3 and Fig. 4 A, Fig. 4 B, when elastic component 130 is spring, can be by elastic-restoring force FkSpring constant is utilized to set the air pressure inside to be held storing container 1.
With reference to Fig. 4 A, Fig. 4 B, the air pressure inside storing container 1 when deformable part 113 is maintained at flat condition (see Fig. 4 A) could possibly be higher than preset air pressure.Thus, the upper surface 111a of open/close portion 111 can close through hole 103, to maintain the airtight conditions stored within container 1 such that it is able to reliably keeps the air pressure inside (see Fig. 4 A) storing container.
But, when the air pressure inside storing container 1 gets lower than preset air pressure (such as, 0.8atm) produce draught head (i.e., store the pressure reduction between container 1 inside and outside) time, the power that this draught head produces is more than the elastic-restoring force produced because of movable link 110 and the coefficient of elasticity of elastic component 130, open/close portion 111 can be pushed down, and deformable part 113 can be made to sink and elastic deformation (see Fig. 4 B) occurs.
With reference to Fig. 4 B, when extraneous air is introduced into storage container 1 due to produced draught head, extraneous air can be introduced into storage container 1 by the through hole 113a of deformable part 113.When the air pressure inside storing container 1 suitably increases in response to the introducing of extraneous air, open/close portion 111 can be moved by movable link 110 and the elastic-restoring force of elastic component 130, thus seals through hole 103 the most airtightly.
So, when the air pressure inside storing container 1 is reduced to less than preset air pressure, extraneous air can be introduced into by the barometric control unit according to an one exemplary embodiment, in order to keeps preset air pressure based on coefficient of elasticity.
Such as, when expectation makes the air pressure inside of storage container be maintained at about 0.8atm, by the coefficient of elasticity of movable link 110 and the coefficient of elasticity of elastic component 130 are carried out suitable combination, and can be designed as having dynamic component 110 and elastic component 130 because of the draught head between atmospheric pressure (1atm) and the air pressure of 0.8atm the elastic-restoring force of elastic recovery.
Owing to elastic component 130 is implemented as spring, so elastic-restoring force F can be estimated by calculating spring constantk(Fk=k(spring constant) × X(standoff distance)).
With reference to Fig. 3 and Fig. 4 A, Fig. 4 B, supporting member 150 comprises the steps that elastic component fixed part 151, in order to fixing elastic component 130；And multiple pore 153, the thickness direction along supporting member 150 runs through this supporting member 150 and is formed.
Supporting member 150 can be made up of plastics or similar rigid material, and it is firm and can not be moved up and down.Supporting member 150 can be fixed on the second contact site 105b of the inner peripheral surface of this housing.
It is positioned at the 3rd inner space C below supporting member 150 and can be connected to store the inner space of container 1.When open/close portion 111 opens through hole 103, extraneous air may pass through the first inner space A, to be introduced in via the pore 113a of movable link 110 and the pore 153 of supporting member 150 in the inner space storing container 1.
According to another one exemplary embodiment shown in Fig. 6, supporting member 150 comprises the steps that framework 151a, is fixedly attached on the second contact site 105b of housing；And multiple support beam 151b, extend from framework 151a towards the central part of this supporting member 150.By this structure, elastic component fixed part 151 can be fixedly fastened on the inner peripheral surface of housing by supporting member 150.
When each supporting leg 151b extends and is connected to elastic component fixed part 151, the adjacent interval between supporting leg 151b can form pore 153.
When the size of pore 153 is bigger, the extraneous air being introduced in the second inner space B can smoothly flow therein in the storage container 1 as the 3rd inner space C.Therefore, supporting member 150 can be implemented by framework 151a and supporting leg 151b.
Therefore, in order to prevent the air pressure inside storing container 1 excessively less than external pressure, available external pressure makes the air pressure inside of storage container 1 suitably raise, and is maintained at desired atmospheric pressure state.
Barometric control unit 100 may be mounted to that on the outer wall storing container 1, to be externally exposed air, thus prevents the air pressure inside storing container 1 from declining abnormally.And, when making air pressure reduce constantly when damage, failure and other reasons due to vacuum pump, can prevent from advance storing the risk that container is destroyed.
Additionally, the spring constant of the coefficient of elasticity of elastic component 130 of barometric control unit 100, i.e. spring can be conditioned, to prevent the air pressure inside storing container 1 from falling below preset air pressure.
According to another one exemplary embodiment of the present invention, barometric control unit 100 comprises the steps that housing, and this housing is formed hollow tubular and has upper surface and open lower surface, runs through this upper surface and is formed with through hole 103, in order to allow introducing extraneous air；Movable link 110, is installed in this housing and can move up and down, to selectively close and open through hole 103 based on external pressure and the difference of the air pressure inside being in weak vacuum state；Supporting member 150, is fixedly mounted in this housing, and spaced apart with the bottom of movable link 110；And elastic component 130, it is fixedly mounted between movable link 110 and supporting member 150.
Movable link 110 comprises the steps that open/close portion 111, in order to open and close through hole 103；Deformable part 113, has multiple pore 113a, and allows open/close portion 111 to move up and down, and these pores run through deformable part 113 along the thickness direction of this deformable part and formed；And elastic component fixed part 115, in order to fix this elastic component 130.Deformable part 113 can be made up of rubber, to allow open/close portion 111 to move up and down.
Elastic component 130 can be implemented as spring.Supporting member 150 comprises the steps that elastic component fixed part 151, in order to fixing elastic component 130；And multiple pore 153, the thickness direction along elastic component 150 runs through this elastic component 150 and is formed.
The barometric control unit 100 of another one exemplary embodiment according to the present invention can be the device worked as valve, and this valve works when the air pressure inside storing container is less than preset air pressure.This barometric control unit 100 can be installed in the position that can carry out installing easily, and this position can be the storage top of container, sidepiece or the rear portion of drawer type or a cell type.
When the elastic component 130 of barometric control unit 100 is spring, adjustable springs constant such that it is able to open and close valve (that is, barometric control unit 100) in predetermined pressure level.Furthermore it is possible to make spring constant different according to being expected to store the preset air pressure of holding in container 1, it is achieved in a kind of device being opened under stress.
Such as, when the air pressure inside storing container 1 is reduced to less than the Reference pressure of 0.8atm, barometric control unit 100 can be opened to allow to introduce extraneous air.So can prevent air pressure inside from falling below preset air pressure (this air pressure expectation be kept), and it is corrupt and the situation such as be dried to avoid being stored in the article stored in container in advance.
Additionally, in order to prevent the air pressure inside storing container to be reduced to less than preset air pressure, and making the article being stored in this storage container be under suitable atmospheric pressure state, spring constant can be adjusted to keep this preset air pressure.
Barometric control unit 100 according to the present invention can be configured to, it is possible to by mobile elastic component 130(, it is spring) and the open/close portion 111(rubber button of movable link 110) open and close through hole 103.
That is, under the suitable air pressure inside state storing container 1, open/close portion 111(rubber button) can push away on the elastic force of spring (that is, elastic component 130), to close through hole 103 airtightly, thus keep the airtight conditions storing container 1.But, it is reduced to less than preset air pressure (such as in the air pressure inside storing container 1, under state 0.8atm), movable link 110 can be deformed (being bent downwardly) by up concave type under the effect of the bigger power of the elastic-restoring force of the ratio spring (i.e. elastic component 130) produced because of pressure reduction, and open/close portion 111 can move down.Thus, through hole 103 can be opened to allow to introduce extraneous air.Here, the predetermined air pressure inside of storage container 1 can be set by regulation spring constant.
With reference to Fig. 4 A, when the difference of the air pressure inside and atmospheric pressure that store container 1 is in the range of preset air pressure, the spring as elastic component 130 can be by pressing open/close portion 111 on its elastic-restoring force, in order to closes through hole 103.
On the other hand, with reference to Fig. 4 B, when the air pressure inside storing container 1 is reduced to less than preset air pressure, deformable part 113 can deform (or being bent downwardly) because of this air pressure inside and the difference of atmospheric pressure up concave type.Thus, open/close portion 111 can move down and extrude elastic component 130, so that elastic component 130 can have elastic-restoring force Fk1。
After through hole 103 is opened due to moving of open/close portion 111, extraneous air can be introduced in storage container 1 via the pore 153 of the pore 113a of movable link 110 and supporting member 150, thus improves the air pressure inside storing container 1.When air pressure inside reaches preset air pressure, open/close portion 111 can move up by the elastic-restoring force of elastic component 130, and to close through hole 103, thus gastight closing stores container 1.
As it has been described above, according to an embodiment of the invention barometric control unit can prevent from storing container air pressure inside fall below preset air pressure, thus improve the freshness being stored in the vegetable stored in container.
