VACUUM GENERATION APPARATUS WITH CLOSED FLUID CIRCUIT EJECTOR SYSTEM, ESPECIALLY FOR VACUUM GENERATION OF HOME REFRIGERATOR CELLS AND THE LIKE Filed May 18, 1964 Fig. 2
INVENTOR LUC/ANO GASBARRO United States Patent 3,216,214 VACUUM GENERATION APPARATUS WITH CLOSED FLUID CIRCUIT EJECTOR SYSTEM, ESPECIALLY FOR VACUUM GENERATION OF HOME REFRIGERATOR CELLS AND THE LIKE Luciano Gasbarro, Florence, Italy, assignor to Breconvuot Anstalt, Vaduz, Liechtenstein, a corporation of Liechtenstein Filed May 18, 1964, Ser. No. 368,156 Claims priority, application Italy, May 21, 1963, 11,600/ 63 Claims. (Cl. 6217()) It is known that for some uses the generation of a relative vacuum is determined by suction systems, these systems being formed by an ejector system with a chamber wherein the vacuum is generated, terminating in correspondence of a profiled nozzle for a pressurized circulating fluid; in general, the water distribution mains having the usual pressure of the mains circuit is directly utilized for the pressurized fluid.
The present invention relates to a vacuum generation system of the aforesaid type, which however avoids the necessity of a connection to an apparatus of the hydric or water mains (cock or the like) determining the vacuum formation with a practically self-acting system. Although the invention is not restricted to this application, it seems that the main application is that for the vacuum generation in a home refrigerator cell, in such a manner as to release the refrigerator from the necessity of a connection with a suitable conduit to a cock or other distribution apparatus of the water mains, or of the installation of an appropriate apparatus of the kind.
Substantially according to the invention, provisions are made for the fluid designed to the suction effect, with a suitable vent means, in the closed circuit being inserted on one side a forced circulation means such as a pump and on the other side a profiled section designed to be combined with an axial nozzle to form an ejector designed to generate the vacuum in the recess connected thereto.
In the embodiment, provisions may be made for a continuous tubular circuit with a suitable circulation pump, in which the suction apparatus is inserted for the vacuum forming and downstream thereto a gas vent means is arranged, practically made up under the form of an expansion passage advantageously connected to a cavity designed to assure the filling and (forming of a sufficient fluid accumulation tank.
For installation in a home refrigerator, the closed conduit or pass'age may be supported on the rear face or at the bottom of the refrigerator casing, for example in a vertical or horizontal arrangement.
For the control of the electric circulation pump provisions may be made for a manual switch or also an automatic system, for instance, combined with the refrigerator cell door and/or of the vacuum cell, while an interruption of the operation may be timed and when the vacuum extent or degree of the vacuum cell reached will be higher than a pre-determined rate.
The invention will be better understood following the description and the accompanying drawing, which illustrates an embodiment of said invention.
In the drawing:
FIG. 1 illustrates a perspective scheme of installation of a home refrigerator;
FIG. 2 illustrates a scheme in a vertical section;
FIG. 3 illustrates a demonstrative scheme; and
FIG. 4 illustrates a scheme of control of the operation of the vacuum apparatus.
As it can be seen diagrammatically in the accompanying drawing, the vacuum-forming system comprises a closed pipe circuit 1 in which a circulation pump 2 is inserted and in the thrust branch thereof, the pipe 1 is coupled to or merges with an ejector housing 1a having within it an ejector nozzle 1b which is coextensive with pipe 1. A conduit or pipe 3 communicates the housing with cell or chamber 5 Where the vacuum is to be effected, with a suitable check valve 3a provided to prevent air from leaking into chamber 5 from pipe circuit 1. Downstream of the ejector 1a and valve 3a, a suitable pipe vent 4 is located, coupled advantageously to a hopper or tank 4a, made up as a funnel which serves both for the accumulation of the fluid and the filling, while the venting of the gases, eventually mixed with the fluid by eflect of the suction, is allowed.
With regard to an installation in a home refrigerator, the plant may be arranged on the rear face of the refrigerator cell 10 in the vertical arrangement as clearly shown in FIGS. 1 and 2, alternatively, provisions may be made for a horizontal arrangement, for example, at the base of the refrigerator. The circuit may be circular.
In particular in the application above statedprovisions being made to generate the vacuum in a cell or hermetic envelope 5 having a door 12, where the conduit 3 is led to-a control of the motor 2a of the pump 2 may be provided for through a consent determined by a switch 7 controlled for instance by the refrigerator door 11 in such a manner as to impart the consent to the operation for the vacuum generation only when the door is closed. On the other side, provisions may be made also for a second switch 8 actuated by a lung membrane 9, for example, an expansible membrance such as a pressure-responsive bellows, which is sensitive to the extent or rate of vacuum in the cell or hermetic envelope 5 so as to break the circuit of the motor 2a of the pump 2 when the desired vacuum rate is thus attained and to restore it when the vacuum rate drops to a certain limiting level, which may be appropriately calibrated.
The closed circuit circulation fluid may be any suit able fluid, consistently with the sucked vapours, especially even water.
In this way a vacuum generation system particularly cheap and which avoids any emulsioning danger with the lubricants of a conventional decompressor is thus obtained.
It is intended that the drawing only illustrates an embodiment, given only as a practical demonstration of the invention, said invention being in conditions as to be varied in the for-ms and arrangement without however departing from the spirit and scope of the invention. For instance, the circulation pump 2 may be of the mechanical control type (for instance connected to the door motion) or an otherwise actuated type.
