Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to a washing machine. Background Art

[0002] At present, common dishwashers on the market generally include a housing and a spray device disposed in the housing. The spray device is used to draw water from the bottom of the housing into a water spray component and spray it into the washing chamber to wash the dishes. The washing chamber volume of most dishwashers is fixed and cannot be changed according to the number of dishes to be washed. When the number of dishes to be washed is small, placing the dishes in a larger washing chamber for washing not only affects the washing effect, but also causes a waste of water resources.

[0003] In addition, for some dishwashers with larger capacity, users are accustomed to placing the dishes in the dishwasher for storage after washing. In this case, if fewer dishes are used for each meal, the stored dishes will need to be washed together when washing the dishes next time, which will also cause a waste of water and electricity resources.

[0004] In response to the above problems, the Chinese utility model patent with patent number CN202023348649.2 (publication number CN215383808U) discloses "A dishwasher", which includes: a box body, having an inner cavity; a partition assembly, arranged in the inner cavity of the box body, for dividing the inner cavity of the box body into relatively independent upper and lower spaces; the partition assembly includes: a fixed plate, horizontally placed in the middle of the box body and connected to the inner wall of the box body; a movable plate, movably arranged on the fixed plate, for cooperating with the fixed plate to separate the upper space from the lower space or connect the upper space with the lower space; also includes: a surrounding plate, arranged on the lower wall surface of the fixed plate, and a relatively independent installation compartment is formed between the fixed plate and the inner wall of the box body; a driving member, arranged in the installation compartment, and the power output shaft passes through the surrounding plate and is connected to the movable plate.

[0005] When the number of dishes to be washed is small, the movable plate of the partition assembly moves relative to the fixed plate to separate the upper space from the lower space. The upper space can be used to store washed dishes, and the lower space can be sprayed and washed separately, which not only makes full use of the box space, but also helps to save energy such as water and electricity. When the number of dishes to be washed is large, the movable plate of the partition assembly moves relative to the fixed plate to connect the upper space with the lower space, and the dishes in the upper space and the lower space are washed at the same time.

[0006] For this type of dishwasher with a side door, when taking and placing dishes on the lower rack, the lower rack is pulled forward to the door body, so that the user can take and place dishes in the dishwasher. The rack is generally a hollow structure surrounded by a number of frame bars to drain water. When contaminated dishes are placed on the lower rack, oil and debris on the dishes may leak out of the rack and contaminate the door body. When the dishwasher is performing a half-chamber wash (i.e., only the lower space is spray-washed), the contaminated upper part of the door body cannot be cleaned. The contamination of the upper part of the door body will affect the storage of the upper space, and thus the split-chamber effect of upper storage and lower washing cannot be achieved. Summary of the invention

[0007] The first technical problem to be solved by the present invention is to provide a cleaning machine capable of preventing oil stains dripping from tableware from contaminating the door body in view of the current status of the prior art.

[0008] The first technical problem to be solved by the present invention is to provide a washing machine capable of preventing oil stains dripping from tableware from contaminating the upper part of the door body in view of the current status of the prior art.

[0009] The second technical problem to be solved by the present invention is to provide a washing machine which can adjust the washing space according to the number of dishes to be washed and can ensure the cleanliness of the upper part of the door body in view of the current status of the prior art.

[0010] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a cleaning machine, comprising

[0011] A box body having an inner cavity with an open front side;

[0012] The door body, the bottom of which is rotatably connected to the box body, and the upper part of which can be deflected forward and backward relative to the box body, thereby opening or closing the opening of the inner cavity; the part where the bottom of the door body is rotatably connected to the box body is called the connecting part;

[0013] A partition assembly is arranged in the inner cavity of the box body, and the partition assembly can separate the inner cavity of the box body into a relatively independent upper space and a lower space;

[0014] It is characterized by: it also includes

[0015] A dirt shielding plate is arranged on the rear wall of the door body, and the dirt shielding plate can reciprocate in a direction close to or away from the connecting portion; when the door body is closed, the dirt shielding plate is located in the upper space or the lower space;

[0016] Drive mechanism, including

[0017] A moving member is arranged in the door body, and the moving member is connected to the dirt shielding plate via a connecting shaft passing through the rear wall surface of the door body;

[0018] The driving assembly is arranged in the door body and is drivingly connected to the moving member, thereby driving the moving member to reciprocate relative to the door body.

[0019] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: when the door body is open, the dirt shielding plate is far away from the connecting part of the door body, and when the door body is closed, the dirt shielding plate is close to the connecting part of the door body and is located in the lower space.

[0020] The driving assembly can have various structural forms, such as a motor and a push rod connected to the motor drive, the push rod directly pushes the moving member, preferably, the movement of the dirt shielding plate toward or away from the connecting portion is defined as movement along the length direction of the door body, and the driving assembly includes

[0021] A driving member, arranged in the door body;

[0022] The connecting component connects the driving member and the moving member, thereby driving the moving member to reciprocate along the length direction of the door body.

[0023] The driving member may be a motor, and the connecting assembly may be a push rod. In order to guide the moving track of the moving member, preferably, the connecting assembly includes a lifting frame, including a first rod body and a second rod body that are cross-arranged and connected by a pin at the intersection, the pin shaft extends in the front-to-back direction when the door body is closed, and a first slide rail and a second slide rail are arranged in the door body in the up-down direction, and the first slide rail and the second slide rail both extend in the left-right direction, the first end of the first rod body is connected to the driving member, and the second end is slidably arranged on the second slide rail and can move along the second slide rail, the first end of the second rod body is slidably arranged on the first slide rail and can move along the first slide rail, the second end of the second rod body is slidably arranged on the second slide rail and can move along the second slide rail, and the second slide rail is fixedly connected to the moving member. The overall height of the lifting frame is adjusted by rotating the first rod body and the second rod body, so that the moving member moves, thereby driving the dirt shielding plate to move.

[0024] Because the dirt shielding plate has a certain width in the left and right directions, in order to ensure the smooth movement of the dirt shielding plate, there are two movable parts arranged at intervals on the left and right, and the two movable parts are connected by a connecting rod. The two ends of the second slide rail are respectively connected to the two movable parts, so that the dirt shielding plate has force points on both sides, can move smoothly, and will not tilt.

[0025] In order to enable the first rod body and the second rod body to rotate relative to each other, thereby changing the height of the lifting frame, a worm wheel is provided at the first end of the first rod body, the worm wheel is located on one side of the first slide rail, and the axis of the worm wheel extends in the front-to-back direction when the door body is closed, and the driving member includes a motor and a worm connected to the motor drive, the worm wheel extends up and down and meshes with the worm wheel. When the motor works, it drives the worm to rotate, and the worm wheel rotates accordingly, driving the first rod body to rotate. During the rotation of the first rod body, the second rod body will also rotate accordingly.

[0026] In order to connect the dirt shielding plate to the connecting shaft, the connecting shaft is formed on the moving part, and the dirt shielding plate is partially arched in the direction away from the door body to form an accommodating portion, and the end of the connecting shaft is fixedly inserted in the accommodating portion. In this way, there is no need to set a component connecting the dirt shielding plate and the connecting shaft, the structure is simplified, and there is no need to open a connecting hole on the dirt shielding plate for the connecting shaft to pass through, and there is no need to consider the sealing problem.

[0027] In order to guide the moving trajectory of the moving part, a fixing part is provided between the moving part and the rear wall of the door body, and a guide groove extending along the length direction of the door body is opened on the wall surface of the fixing part facing the moving part, and the moving part is provided with a guide block located in the guide groove, and the guide block can move along the guide groove.

[0028] The connecting shaft must pass through the fixing part and the rear wall of the door body to be connected with the dirt shielding plate. In order to prevent water vapor from leaking into the strip groove through which the connecting shaft passes and damaging the electrical components in the door body, a first strip groove through which the connecting shaft passes is provided on the rear wall of the door body, and a second strip groove through which the connecting shaft passes is provided on the fixing part. The first strip groove and the second strip groove correspond to each other, and a groove is formed on the outer periphery of the second strip groove on the wall surface of the fixing part facing the dirt shielding plate. A folded edge is formed on the periphery of the first strip groove extending toward the fixing part. The folded edge is located in the groove, and a first sealing ring is provided between the folded edge and the side wall of the groove. In this way, water vapor cannot enter the interior of the door body from between the fixing part and the rear wall of the door body.

[0029] In order to further prevent water vapor from leaking into the strip groove through which the connecting shaft passes and damaging the electrical components in the door body, a second sealing ring is provided between the wall of the fixed part facing the moving part and the moving part, and the second sealing ring is arranged around the outer periphery of the second strip groove. In this way, water vapor cannot enter the interior of the door body from between the fixed part and the moving part. The first sealing ring and the second sealing ring cooperate with each other to achieve sealing between the driving mechanism and the door body.

[0030] In order to guide the moving track of the dirt shielding plate, two guide rails extending along the length direction of the door body are arranged at intervals in the left and right directions on the rear wall surface of the door body, each of the guide rails has a slide groove extending along its length direction, and sliding parts are arranged on both the left and right sides of the dirt shielding plate, and the sliding parts are located in the slide grooves on the corresponding sides and can slide along the slide grooves. The moving track of the dirt shielding plate is guided by the cooperation of the sliding parts and the slide grooves.

[0031] The sliding part may be in the shape of a cubic block, and the slide groove may be a straight strip groove. However, in order to position the dirt shielding plate and the guide rail relative to each other in a direction perpendicular to the moving direction thereof, the rear wall of the door body is partially recessed forward to form a recess, and the guide rail and the dirt shielding plate are both arranged in the recess. There is a gap between the guide rail and the side wall of the recess, and the guide rail is provided with an embedding groove with a notch facing the gap and connected to the gap. The embedding groove and the gap together form an L-shaped slide groove, and the sliding part is L-shaped, including a first positioning part embedded in the gap and a second positioning part embedded in the embedding groove. The second positioning part is embedded in the embedding groove, so that the sliding part is not easy to escape from the slide groove.

[0032] The guide rail can be installed on the door body by screws, but this requires drilling holes in the door body. If the holes are not sealed well, water vapor will enter the door body and damage the electrical components in the door body. Therefore, preferably, the guide rail is attached to the rear wall of the door body. In this way, there is no need to drill holes in the door body and there is no need to consider the sealing problem.

[0033] In order to prevent the accumulation of oil stains on the dirt shielding plate, a spray arm is rotatably arranged in the lower space of the box body. The spray arm is used not only for washing tableware but also for washing the dirt shielding plate.

[0034] When the door is open and the lower dish rack is placed on the door, the oily dirt dripped from the dishes will also contaminate the area of ​​the door exposed outside the dirt shielding plate. When the cleaning machine is working, this part of the door will be blocked by the dirt shielding plate, which will cause the door to be contaminated and unable to be cleaned. Therefore, preferably, when the door is closed, there is a gap between the dirt shielding plate and the rear wall of the door. In this way, when washing dishes in the lower space, the washing liquid can enter the gap between the dirt shielding plate and the door to clean the door.

[0035] The technical solution adopted by the present invention to solve the third technical problem is: the partition assembly includes

[0036] A fixing plate, which is horizontally placed in the middle of the box body and connected to the inner side wall of the box body;

[0037] The movable plate is arranged to be movable forward and backward relative to the fixed plate, and is used to cooperate with the fixed plate to separate the upper space from the lower space or to connect the upper space with the lower space.

[0038] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention provides a movable dirt shielding plate on the door body, so that the oil stains on the tableware will drip onto the dirt shielding plate and will not pollute the door body. After the door body is closed, the washing water in the upper space or the lower space where washing work is performed can rinse the dirt shielding plate, which will not affect the next use of the dirt shielding plate; 2. For a washing machine that stores tableware in the upper space and washes tableware in the lower space, when the door body is open, the dirt shielding plate is away from the connecting part of the door body (that is, located at the front part of the door body), so that the oil stains dripping from the tableware on the lower bowl rack will fall on the dirt shielding plate and will not directly fall on the front part of the door body; when the door body is closed, the dirt shielding plate is close to the connecting part of the door body (that is, located at the lower part of the door body). And it is located in the lower space, and will not affect the storage function of the upper space; 3. When the number of dishes to be washed is small, the movable plate of the partition assembly moves relative to the fixed plate to separate the upper space from the lower space, and half-cavity washing is performed. The upper space can be used to store and store washed dishes, and the lower space can be sprayed and cleaned separately, which not only makes full use of the box space, but also helps to save energy such as water and electricity; when the number of dishes to be washed is large, the movable plate of the partition assembly moves relative to the fixed plate to connect the upper space with the lower space, and a full-cavity wash is performed, while the dishes in the upper space and the lower space are washed; in addition, even if some oil stains drip from the upper part of the door body, the upper part of the door body can also be rinsed clean during the full-cavity wash.
