Description

  • The present invention refers to a washing machine with two compartments, in particular to a front load washing machine for household use. [0001]
  • It is generally known that in modern front load washing-machines a drum suitable to contain the laundry to be washed is situated in a central position of the washing machine and it has an opening on the front of the machine. Such drum is revolvingly mounted into a container, called washing tub, that is destined to contain the washing water and equipped for the anchorage of suspension organs that allow it to remain suspended inside a cabinet containing the washing machine. [0002]
  • The loading of the drum forces an operator to continuous and sudden bending over for the positioning of the laundry to be washed inside the drum situated in a low position as regards the normal aptitudes of the operator. [0003]
  • In order to facilitate the loading of the laundry to be washed top load washing machines have been realised, that is in which the washing drum is provided with an opening on its top instead of the normal front opening. [0004]
  • In other cases washing machines have been realised in which the washing tub containing the drum is inclined at a certain angle as regards a horizontal axis in order to facilitate the loading of laundry to be washed. [0005]
  • In view of the state of the art herein described, scope of the present invention it is to realise a washing machine that allows an easier loading of the laundry to be washed. [0006]
  • According to the present invention, such scope is attained by means of a washing machine for household use comprising a washing tub mounted inside a cabinet, a drum containing the laundry to be washed mounted inside said washing tub, wherein it comprises a top compartment and a bottom compartment, said top compartment being suitable to contain said washing tub and said bottom compartment being openable from the outside, said bottom compartment providing to raise said washing tub in a such way so as to facilitate the loading and the unloading of the laundry from the drum. [0007]
  • Owing to the present invention it is possible to realise a washing machine that owing to a height greater than the known washing machines makes the operation of loading and unloading of the laundry to be washed easier.[0008]
  • The characteristics and the advantages of the present invention will become evident from the following detailed description of an embodiment thereof, that is illustrated as a non-limiting example in the enclosed drawings, in which: [0009]
  • FIG. 1 is a schematic side view of a washing machine according to an embodiment of the present invention; [0010]
  • FIG. 2 is a partially sectioned schematic front view of the washing machine in FIG. 1; [0011]
  • FIG. 3 is a schematic side view of a washing machine according to a variation of the embodiment of the present invention; [0012]
  • FIG. 4 is a partially sectioned schematic front view of the washing machine in FIG. 3.[0013]
  • With reference to FIGS. 1 and 2 a front load washing machine is shown that is provided with a [0014] cabinet 1 comprising two compartments: one top compartment 2 and one bottom compartment 3. In the top compartment 2 a washing tub 4 is housed that is suspended inside the cabinet 1 by means of organs of suspension 5 comprising suspension springs 6 and shock-absorbers 7. The suspension springs 6 connect the washing tub 4 to the top of the cabinet 1 while the shock-absorbers 7 connect the bottom part of the tub 4 with the bottom of the cabinet 1 and they are fastened to vertical projections 10 of the bottom of the cabinet 1. The pairs of springs 6 and shock-absorbers 7 are inclined in such a way that the distance between either the two springs 6 or the two shock-absorbers 7 is greater in the points in which they are connected with the top or the bottom (precisely to the projections 10) of the cabinet 1 as compared with the distance in the points in which they are connected with the tub 4. The washing tub 4 comprises a cylindrical drum 8 coaxial to it and destined to contain the laundry to be washed; said drum 8 is supported by the cabinet 1 in a revolving way around a horizontal axis A inside the washing tub 4. Drum 8 is closed by a window 9 that is hinged to the cabinet 1 of the washing machine; said window 9 is preferably provided with a fixed or removable detergent dispenser 50.
  • The [0015] bottom compartment 3 comprised between the shock-absorbers 7 is openable from the outside, and it households a trolley 11 that is sliding on lateral guides 12 and containing a container 13 suitable to contain the laundry to be washed or used as tools holder. Such container 13 has such dimensions that once it is extracted from the trolley 11, it can be placed on upper part 130 of same trolley 11 opened so as to facilitate the loading or unloading of the laundry.
  • The presence of the [0016] compartment 3 in the cabinet 1 determines a greater height of the washing machine shown in the annexed figures as compared with the known washing machines; in fact if the height of the known washing machines is around 80 cm, the washing machine according to the present invention has a height of approximately 120 cm. This allows an easier loading and unloading of the laundry from the drum 8 since the continuous bending over on behalf of a operator can be prevented.
  • The positioning of [0017] counter-weights 14, 15 is realised in such a way that the barycentre axis of the washing tub 4 is maintained inside the vertical projection of the same tub during the operation of the washing machine, especially during the centrifugal stage. For such reason the positioning of the counter-weights is done under the washing tub 4 in a way symmetrical to the barycentre axis. By taking advantage also of the weight of a motor 16 serving for the rotation of drum 8, the positioning of the counter-weights can preferably be carried out by subdividing the load into three units; two equal units 14 are arranged on the back as regards the washing tub 4 and they are positioned at the sides of the motor 16; a unit 15 is arranged on the front as regards the washing tub 4 and it is facing the units 14 and the motor 16. If for instance it is necessary to utilise a total counter-weight of approximately 34 kg, an optimal subdivision of the load is obtained by using the unit 14 of approximately 4 kg and a unit 15 of 20 kg, by taking advantage of the fact that the weight of motor 16 is of approximately 6 kg.
  • In the washing machine shown in FIGS. 1 and 2, the [0018] filtering element 17 is arranged in a higher position as compared with the known washing machines; this allows an easier operation of cleaning or of substitution of the filtering cartridge and it allows to contain the volume of inert water.
  • In FIGS. 3 and 4 a washing machine according to a variation of the aforementioned embodiment is shown. The washing machine of such variation shows, in a different way, a [0019] washing tub 4 with axis B inclined by 8° or 12° as regards the horizontal axis A (the inclination is measured in counter-clockwise direction), with a different positioning of the counter-weights and a different positioning of the suspension organs of the washing tub.
  • [0020] Such washing tub 4 is provided both at its top as well as at its bottom with pairs of shock-absorbers 18 that are suitable to keep it suspended inside the cabinet 1 and to limit its oscillations during the operation of the washing machine. The shock-absorbers are mounted onto the tub 4 in points belonging to a vertical plane perpendicular to the horizontal axis A and passing through the theoretical barycentre of the tub 4 and of the drum 8. The pairs of top and bottom shock-absorbers 18 are inclined in such a way that the distance between the two is greater in the points in which they are connected with the bottom (precisely with the projections 10) or with the top of cabinet 1 as compared with the distance in the points in which they are connected with the tub 4.
  • The positioning of the [0021] counter-weights 24, 25 is realised in such a way that the barycentre axis of the washing tub 4 is maintained inside the vertical projection of the same tub during the operation of the washing machine, especially during the centrifugal stage. For such reason the positioning of the counter-weights is done under the washing tub 4 in symmetrical way to the barycentre axis. By taking advantage also of the weight of a motor 26 suitable to the rotation of the drum 8, the positioning of the counter-weights can preferably be done by subdividing the load into three units, as already mentioned for the washing machine with horizontal axis tub, but with a different loads distribution. Two equal units 24 are arranged on the back of the washing tub 4 and they are arranged at the sides of the motor 26; a unit 25 is arranged on the front as regards the washing tub 4 and it is facing the units 24 and the motor 26. If as an example it is necessary to use a total counter-weight of approximately 34 kg, an optimal subdivision of such load is obtained by using the unit 24 of approximately 8 kg and a unit 25 of 12 kg by taking advantage of the fact that the weight of the motor 26 is of approximately 6 kg.
