Description

The present invention relates to the field of washing machines, and in particular, to a drawer-type laundry treating device and a composite washing machine.
In an existing washing machine (such as a drum washing machine), a position of an inlet for laundry is relatively low, and it is usually necessary to bend over to put in or take out laundry, which brings inconvenience to user operation.
In an improved washing machine, a drawer-type washing device for supporting the washing machine is provided. On one hand, the position of the inlet of the washing machine is elevated and the user operation is facilitated. On the other hand, the drawer-type device is also adapted to wash small-sized laundry, avoiding large consumption of water and electricity caused by washing by using a large-sized washing machine.
In such type of improved washing machine, the drawer-type washing device includes a dedicated door (also referred to as a "lid"). After the drawer-type device is pulled out, the door needs to be opened manually to put in or take out laundry and then the door is closed. For example, in the patent file whose publication number is CN105624964A (entitled "DRAWER-TYPE WASHING DEVICE", which is referred to as "existing document 1" hereinafter), the drawer-type washing device includes a door (that is, the "upper lid 10" described in the specification thereof). In the patent file whose publication number is CN101617077A (entitled "COMPOSITE WASHING MACHINE AND CONTROL METHOD THEREOF", which is referred to as "existing document 2" hereinafter), the drawer-type washing device includes a door (that is, the "drum door 141" described in the specification thereof). In the patent file whose publication number is CN105177917A (entitled "LAUNDRY TREATING DEVICE", which is referred to as "existing document 3" hereinafter), the drawer-type washing device includes a door (that is, the "door 49" described in the specification thereof).
However, when such type of improved washing machine is used, the door of the drawer-type washing device needs to be manually operated twice (that is, opening and closing the door), which still brings inconvenience to the user operation. In addition, if the drawer-type washing device is used for a long term, the door is opened and closed frequently, causing frequent friction between the door and a box body of the drawer-type washing device, which affects a sealing effect of the door.
The technical problems resolved in embodiments of the present invention are inconvenience caused by operating a door of a drawer-type washing device and a reduced sealing effect of the drawer-type washing device.

In the field of washing machines, whether for a washing machine adapted to wash large-sized laundry or a washing machine adapted to wash small-sized laundry (such as a small washing machine for children, a mini washing machine, and a drawer-type washing device), a dedicated door is provided at the position of an inlet for laundry. In addition, a door seal connected to the door is further provided, so that the washing machine may be sealed when the door is closed. For example, in an existing drawer-type washing device, as described in the related art, the existing documents 1 to 3 respectively provide components adapted for horizontal movement (that is, the "moving portion 20", the "drawer 120", and the "drawer 3"), where a dedicated door (that is, the "upper lid 10", the "drum door 141", and the "door 49") is disposed on an upper part of the component.
Different from the dedicated door for putting in or taking out laundry in the prior art, in the technical solutions of the present invention, a drawer-type laundry treating device includes a body adapted for horizontal movement. The body does not include a dedicated door. Instead, it is set that a cavity of the body is exposed when the body horizontally moves outwards relative to a fixed portion of the drawer-type laundry treating device. Compared with the dedicated door provided in the prior art, the directly exposed cavity in the technical solutions of the present invention can not only increase a cross-sectional area for putting in or taking out laundry, but also avoid inconvenience caused by manually opening and closing the door.
Different from the door seal provided in the prior art to seal the washing machine when the door is closed, in the technical solutions of the present invention, the drawer-type laundry treating device includes a mechanical transmission portion adapted to provide tight joint between the body and a movable plate, so that the cavity can be sealed. Compared with the door seal provided in the prior art, the mechanical transmission portion in the technical solutions of the present invention is adapted to dynamically adjust a degree of the joint between the body and the movable plate within a manufacturing tolerance thereof, so that the cavity can be effectively sealed even when there is an abrasion on a surface where the body and the movable plate are joined.
As shown in the accompanying drawings of the present invention, the drawer-type laundry treating device includes a fixed portion and a moving portion including a body. Observing the drawer-type laundry treating device from a front view along a direction of the body horizontally moving inwards, six directions, which are up, down, left, right, front, and back, can be determined (refer to the directions shown in the accompanying drawings). Up and down respectively indicate vertical upward and vertical downward directions, left and right respectively indicate directions to the left and right in the visual angle, and front and back respectively indicate directions of the body horizontally moving outwards and inwards. It should be understood that, the drawer-type laundry treating device may alternatively be observed from another visual angle, and there are directions corresponding to the visual angle. Therefore, the exemplary directions in the accompanying drawings only help describe the technical solutions of the embodiments of the present invention, and should not constitute any limitation to these solutions.
To make the objectives, features, and beneficial effects of the embodiments of the present invention more comprehensible, specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of an overall structure of a drawer-type laundry treating device according to an embodiment of the present invention. FIG. 2 to FIG. 4 are specific schematic structural diagrams of the drawer-type laundry treating device. FIG. 5 and FIG. 6 are respectively schematic lateral diagrams of the drawer-type laundry treating device when the body of the moving portion horizontally moves outwards and inwards relative to the fixed portion. FIG. 7 and FIG. 8 are respectively schematic side views of the drawer-type laundry treating device when the body horizontally moves outwards and inwards relative to the fixed portion.
As shown in FIG. 1, a drawer-type laundry treating device 100 has a function related to laundry treatment, for example, the drawer-type laundry treating device may be used to receive, wash, or dry laundry. When the drawer-type laundry treating device 100 is used to receive laundry, space in a cavity 104 may receive small-sized laundry. When the drawer-type laundry treating device 100 is used to wash laundry, a washing device may be disposed in the cavity 104, and the cavity 104 is connected to a washing liquid supply pipe, a water inlet pipe, and a drainpipe. When used to dry laundry, the drawer-type laundry treating device 100 may include components such as a heat exchanger, a ventilation system, a rotary drum, and a control system. The laundry includes clothes, bed sheets, shoes and hats, mops, rags, floor mats, and carpets.
The drawer-type laundry treating device 100 includes a drawer-like structure and function, and includes a fixed portion 101 and a moving portion 102. The fixed portion 101 is adapted to accommodate and support the moving portion 102, and the moving portion 102 is adapted to move at least partially outside the fixed portion 101 relative to the fixed portion 101. A handle may be disposed on the moving portion 102 to help a user to move the moving portion 102 horizontally.
The moving portion 102 includes a body 103 with a cavity 104 and a movable plate 105 disposed above the body 103. The drawer-type laundry treating device 100 includes a mechanical transmission portion 106 adapted to cause the movable plate 105 to vertically move upwards to expose the cavity 104 when the body 103 horizontally moves outwards relative to the fixed portion 101 and cause the movable plate 105 to vertically move downwards to seal the cavity 104 when the body 103 horizontally moves inwards relative to the fixed portion 101. In the prior art, the moving portion is connected to the door for putting in or taking out laundry in a manner such as hinged connection, which increases operations of manually opening and closing the door. In the technical solutions of the present invention, the body 103 and the movable plate 105 are not directly connected, but are selectively separated or joined through the mechanical transmission portion 106, which avoids inconvenience caused by manually opening and closing the door.
The body 103 or the movable plate 105 may be provided with a sealing member at a joint surface therebetween, which is adapted to seal the cavity 104 when the movable plate 105 vertically moves downwards and abuts against the body 103, thereby completely isolating interior space of the cavity 104, which can prevent water leakage and thrown-out foreign objects during washing, and affect heat exchange and ventilation during drying.
During long-term use of the drawer-type laundry treating device 100, the body 103 and the movable plate 105 are frequently joined or squeezed, causing abrasion on contact surfaces of the body 103 and the movable plate 105, which affects a sealing effect of the cavity 104. In an embodiment of the present invention, a manufacturing tolerance of the mechanical transmission portion 106 is determined according to a total thickness of the abrasion of the body 103 and the movable plate 105, so that when the contact surfaces of the body 103 and the movable plate 105 are worn out, the mechanical transmission portion 106 may cause the movable plate 105 to vertically move downwards to a contact position that may be reached without abrasion when the body 103 horizontally moves inwards relative to the fixed portion 101. Further, the mechanical transmission portion 106 transmits within the manufacturing tolerance thereof, to cause the movable plate 105 to continue to vertically move downwards by a distance equal to the total thickness of the abrasion, so that the body 103 and the movable plate 105 are joined and the cavity 104 is sealed. That is, the mechanical transmission portion 106 is adapted to transmit within the manufacturing tolerance thereof, to cause the movable plate 105 to vertically move downwards to seal the cavity 104 when the body 103 horizontally moves inwards relative to the fixed portion 101. With continuous use of the drawer-type laundry treating device 100, the total thickness of the abrasion of the body 103 and the movable plate 105 changes. By setting the range of the manufacturing tolerance, the change of the total thickness of the abrasion can be dynamically adapted to, ensuring that the body 103 and the movable plate 105 can be joined and the cavity 104 is sealed.
The mechanical transmission portion 106 includes a mechanical transmission portion based on gear transmission and a mechanical transmission portion based on chain transmission, which have a conventional design known in the field. For example, the gear transmission is formed by intermeshing of two gears respectively mounted on a driving shaft and a driven shaft, and the chain transmission is formed by transmission of two gears and one closed chain.
As shown in FIG. 2 to FIG. 4, the moving portion includes a body 201 and a movable plate 207. The fixed portion may include a body structure, and may further include a support frame (208, 209), a guide rail 202, and a sliding rail 206. The guide rail 202 includes a first guide rail and a second guide rail. The support frame is adapted to support the moving portion. The first guide rail and the second guide rail are fixed to the support frame, disposed on a left side and a right side of the support frame, and extend between a front side and a rear side of the support frame. The sliding rail 206 is disposed on a rear upper part of the support frame. The first guide rail and the second guide rail are adapted for horizontal movement of the body 201, and the sliding rail 206 is adapted for vertical movement of the movable plate 207. The support frame may be made of metal, such as a metal stamping plate, to support the weight of the moving portion.
In an embodiment, the support frame includes a first support frame 208 and a second support frame 209. The first support frame 208 and the second support frame 209 are respectively disposed on a front side and a rear side of the body 201. The first guide rail and the second guide rail are both fixed to the first support frame 208 and the second support frame 209 and extend there between. The sliding rail 206 is disposed on an upper part of the second support frame 209.
In another embodiment, the fixed portion includes a fixed plate 210 that is fixed to the support frame, disposed on the left side and the right side of the support frame, and extend between the front side and the rear side of the support frame. The support frame and the fixed plate 210 jointly provide structural support to the moving portion.
Compared with FIG. 2, the structure shown in FIG. 3 is removed of the fixed plate 210 to expose a specific structure of the mechanical transmission portion 106.
As shown in FIG. 5 and FIG. 6, the mechanical transmission portion is a mechanical transmission portion based on gear transmission, is disposed on a left side and/or a right side of the body 201, and includes a gear 203, a rack 204, a connecting rod 205, and a guide pin 212, a rotating shaft 211 of the gear 203 is fixed to the fixed portion, the connecting rod 205 is disposed along a vertical direction and is fixed to the movable plate 207, the rack 204 is disposed along the vertical direction and is fixed to the connecting rod 205 or is integrally disposed with the connecting rod 205, and the guide pin 212 is disposed on an outer side of the body 201, where when the body 201 horizontally moves, the guide pin 212 pushes the gear 203 to rotate and then pushes the rack 204 meshing with the gear 203, the connecting rod 205, and the movable plate 207 to move in the vertical direction.
Specifically, as shown in FIG. 5, in a case that the body 201 horizontally moves outwards relative to the fixed portion, when the guide pin 212 is in contact with the gear 203, because the guide pin 212 is higher than the rotating shaft 211 of the gear 203, the height difference forms a driving force to push the gear 203 to rotate (it is shown in the locally enlarged diagram that the gear 203 rotates counterclockwise), thereby pushing the rack 204 meshing with the gear 203 to vertically move upwards and then pushing the connecting rod 205 and the movable plate 207 to vertically move upwards. As shown in FIG. 6, in a case that the body 201 horizontally moves inwards relative to the fixed portion, when the guide pin 212 is in contact with the gear 203, because the guide pin 212 is higher than the rotating shaft 211 of the gear 203, the height difference forms a driving force to push the gear 203 to rotate (it is shown in the locally enlarged diagram that the gear 203 rotates clockwise), thereby pushing the rack 204 meshing with the gear 203 to vertically move downwards and then pushing the connecting rod 205 and the movable plate 207 to vertically move downwards.
In the embodiment shown in FIG. 7, in a case that the body 201 horizontally moves outwards relative to the fixed portion, the guide pin 212 disposed on the outer side of the body 201 pushes the gear 203 to rotate counterclockwise, thereby pushing the rack 204 meshing with the gear 203 to vertically move upwards and then pushing the connecting rod 205 and the movable plate 207 to vertically move upwards (refer to the upper left sub-diagram, the upper right sub-diagram, and the lower left sub-diagram in FIG. 7).
After the guide pin 212 is detached from the gear 203, the body 201 may continue to horizontally move outwards (refer to the lower right sub-diagram in FIG. 7).
In the embodiment shown in FIG. 8, in a case that the body 201 horizontally moves inwards relative to the fixed portion, the body 201 first horizontally moves inwards (refer to the upper left sub-diagram in FIG. 8). When the guide pin 212 disposed on the outer side of the body 201 is in contact with the gear 203, the guide pin 212 pushes the gear 203 to rotate clockwise, thereby pushing the rack 204 meshing with the gear 203 to vertically move downwards and then pushing the connecting rod 205 and the movable plate 207 to vertically move downwards (refer to the upper right sub-diagram, the lower left sub-diagram, and the lower right sub-diagram in FIG. 8).
The gear 203 may be a special-shaped gear configured to provide a relatively great instantaneous angular velocity when the movable plate 207 vertically moves downwards and comes into contact with the body 201, so that the movable plate 207 has relatively great speed and pressure to be joined with the body 201, thereby effectively sealing the cavity.
FIG. 9 is a schematic structural diagram of a composite washing machine according to an embodiment of the present invention. The composite washing machine 300 includes a main washing machine 310 and a drawer-type laundry treating device 320 (that is, the drawer-type laundry treating device 100 and the drawer-type laundry treating device 200 described in the foregoing), where the main washing machine 310 is configured to wash and/or dry laundry, and the drawer-type laundry treating device 320 is configured to support the main washing machine.
Although the present invention is disclosed above, the present invention is not limited thereto. Any person skilled in the art can make various variations and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
