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 second 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 third 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 open end 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] A bowl basket is arranged in the lower space of the inner cavity so as to be movable forward and backward, and when the door body is opened, the bowl basket can be moved onto the door body;

[0015] It is characterized by: it also includes

[0016] A lever, mounted on the bowl basket;

[0017] The dirt shielding plate is arranged on the rear wall of the door body. The dirt shielding plate is provided with a blocking portion that can resist the lever, so that the dirt shielding plate can reciprocate in the direction close to or away from the connecting portion. When the door body is closed, the dirt shielding plate is pushed into the upper space or the lower space by the lever.

[0018] 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.

[0019] In the above scheme, in order to enable the lever to push the dirt shielding plate to the required position, the movement of the dirt shielding plate toward or away from the connecting part is defined as movement along the length direction of the door body, and the first stop part and the second stop part are provided on the dirt shielding plate along the length direction of the door body at intervals, and the first stop part is away from the connecting part of the door body relative to the second stop part, and the first stop part and the second stop part together constitute the above-mentioned stop part, and the first stop part and the second stop part are both located on the moving path of the lever and can resist the lever, and the second stop part can be crossed by the lever.

[0020] The lever can be deformed to pass over the second stop when passing through the second stop, but the lever needs to be made of a flexible material, which will weaken the pushing force of the lever on the dirt shielding plate. Therefore, in order to enable the lever to pass over the second stop, the lever includes a rod body extending vertically and a bent section formed by bending the lower end of the rod body forward. A positioning member is provided on the bowl basket. The rod body passes through the positioning member and can move up and down relative to the positioning member under the action of an external force. The front end of the bent section can abut against the first stop, and the connection between the lower end of the rod body and the bent section can abut against the second stop. When passing through the second stop, the lever can be lifted to pass over the second stop, otherwise it will affect the bowl basket from entering the box backwards, or affect the bent section from entering between the first stop and the second stop.

[0021] In order to enable the lever to move upwards and pass over the second stop without manually lifting the lever when the bowl basket moves backwards, the bending section is connected to the lower end of the rod body by a transitional arc structure. In this way, when the lever moves backwards and contacts the second stop, compression occurs between the arc structure and the second stop, and the dirt shielding plate has reached the limit position and cannot move any further, so the lever is forced to move upwards. The arc structure is designed to facilitate the upward movement of the lever.

[0022] Because the rear wall of the door body is generally not a flat plane, in order to ensure that the lever can smoothly move backward after passing the second stopper, the rear wall of the door body is partially recessed forward to form a concave portion, the dirt shielding plate is arranged in the concave portion, and the side wall of the concave portion adjacent to the bottom of the door body is an inclined surface inclined forward along the length direction of the door body. The arc structure of the lever interacts with the inclined surface, and because the door body is fixed, it will force the lever to move upward.

[0023] In order to ensure that the lever can smoothly push the dirt shielding plate, the lever has two levers spaced apart from each other, the upper ends of the two levers are connected by a connecting rod, the two levers and the connecting rod together constitute a toggle member, and the toggle member has one or at least two spaced apart from each other in the left and right directions. In this way, the dirt shielding plate has multiple force points in the left and right directions and can move smoothly.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] When the door is opened 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 is 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 corresponding part of the door.

[0029] The technical solution adopted by the present invention to solve the third technical problem is: the partition assembly includes

[0030] 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;

[0031] 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.

[0032] 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 is performed can rinse the dirt shielding plate, which will not affect the next use of the dirt shielding plate; 2. The present invention provides a lever on the bowl basket, and during the process of pushing and pulling the bowl basket, the lever pushes the dirt shielding plate to move to the corresponding position, so that there is no need to separately provide a mechanism for driving the dirt shielding plate to move, the structure is simple, and there is no need to separately push and pull the dirt shielding plate manually, which is convenient to use; 3. 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, It will not fall directly on the front 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 is located in the lower space, which will not affect the storage function of the upper space; 4. 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 there are more dishes to be washed, 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 at the same time; 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.

[0043] The present invention is further described in detail below with reference to the accompanying drawings.

[0044] like Figures 1 to 10 As shown, the cleaning machine of this preferred embodiment includes a housing 1, a door body 2, a partition assembly 3, a dirt shielding plate 4, a spray arm 5, a bowl basket 7, and a lever 8.

[0045] like Figure 1 , 6 As shown in Figures 10 and 10, the box body 1 has an inner cavity 11 with an open front side, the bottom of the door body 2 is rotatably connected to the box body 1, and the upper part of the door body 2 can be deflected forward and backward relative to the box body 1, so as to open or close the opening of the inner cavity 11. The part where the bottom of the door body 2 is rotatably connected to the box body 1 is called a connecting part. Figure 4 In the embodiment, the part where the door body 2 is connected to the hinge 201 is the connection part. The rotation connection between the door body 2 and the box body 1 adopts the existing structure, which will not be described in detail here.

[0046] The partition assembly 3 is arranged in the inner cavity 11 of the box body 1, and the partition assembly 3 can separate the inner cavity 11 of the box body 1 into relatively independent upper space 111 and lower space 112. In this embodiment, the partition assembly 3 includes a fixed plate 31 and a movable plate 32, the fixed plate 31 is horizontally placed in the middle of the box body 1 and connected to the inner side wall of the box body 1, and the movable plate 32 is arranged to be able to move forward and backward relative to the fixed plate 31, and is used to cooperate with the fixed plate 31 to separate the upper space 111 from the lower space 112 or connect the upper space 111 with the lower space 112.

[0047] When the number of dishes to be washed is small, the movable plate 32 of the partition assembly 3 moves relative to the fixed plate 31 to separate the upper space 111 from the lower space 112, and half-cavity washing is performed. The upper space 111 can be used to store washed dishes, and the lower space 112 can be spray washed separately; when the number of dishes to be washed is large, the movable plate 32 of the partition assembly 3 moves relative to the fixed plate 31 to connect the upper space 111 with the lower space 112, and full-cavity washing is performed, and the dishes in the upper space 111 and the lower space 112 are washed at the same time.

[0048] As for how the movable plate 32 moves back and forth, and how the movable plate 32 cooperates with the fixed plate 31 to separate or connect the upper space 111 and the lower space 112, you can refer to the Chinese utility model patent "A Dishwasher" with patent number CN202023348649.2 (announcement number CN215383808U) in the background technology.

[0049] like Fig.10 As shown, a spray arm 5 is rotatably provided in the lower space 112 , and the spray arm 5 may adopt an existing structure. Of course, the spray arm 5 may also be provided in the upper space 111 .

[0050] like Figure 4 , 9 As shown, the dirt shielding plate 4 is arranged on the rear wall surface 20 of the door body 2, and the dirt shielding plate 4 can reciprocate toward or away from the connecting part of the door body 2. The movement of the dirt shielding plate 4 toward or away from the connecting part is defined as movement along the length direction of the door body 2. When the door body 2 is open, the dirt shielding plate 4 is away from the connecting part, that is, the dirt shielding plate 4 is located at the front part of the door body 2. When the door body 2 is closed, the dirt shielding plate 4 is close to the connecting part, that is, the dirt shielding plate 4 is located at the lower part of the door body 2 and in the lower space 112, and there is a gap between the dirt shielding plate 4 and the rear wall surface of the door body 2.

[0051] like Figure 5As shown, two guide rails 21 are arranged on the rear wall 20 of the door body 2 at intervals along the left-right direction, each guide rail 21 extends along the length direction of the door body 2, and the guide rail 21 is glued to the rear wall 20 of the door body 2. Each guide rail 21 has a slide groove 211 extending along its length direction, and the left and right sides of the dirt shielding plate 4 are provided with sliding parts 40, which are located in the slide groove 211 on the corresponding side and can slide along the slide groove 211. In the present embodiment, the rear wall surface 20 of the door body 2 is partially recessed forward to form a recess 22, and the guide rail 21 and the dirt shielding plate 4 are both arranged in the recess 22. There is a gap 221 between the guide rail 21 and the side wall of the recess 22, and a groove 212 is provided on the guide rail 21, with a notch facing the gap 221 and connected to the gap 221. The groove 212 and the gap 221 together form an L-shaped sliding groove 211, and the sliding portion 40 is L-shaped, including a first positioning portion 411 embedded in the gap 221 and a second positioning portion 412 embedded in the groove 212.

[0052] The movement track of the dirt shielding plate 4 is guided by the cooperation between the sliding portion 40 and the sliding groove 211 ; and the second positioning portion 412 is embedded in the embedding groove 212 , so that the sliding portion 40 is not easy to escape from the sliding groove 211 .

[0053] like Figure 1 , 7 As shown, the bowl basket 7 is arranged in the lower space of the inner cavity 11 so as to be movable forward and backward, and when the door body 2 is opened, the bowl basket 7 can be moved onto the door body 2. The bowl basket 7 can adopt an existing structure, and the structure of how the bowl basket 7 is moved onto the door body 2 is also an existing technology and will not be described in detail here.

[0054] like Figures 1 to 4 As shown in , 7 to 9, the lever 8 is installed on the bowl basket 7, and the dirt shielding plate 4 is provided with a blocking portion that can block the lever 8. In this embodiment, the dirt shielding plate 4 is provided with a first blocking portion 41 and a second blocking portion 42 at intervals along the length direction of the door body 2. The first blocking portion 41 and the second blocking portion 42 together constitute the aforementioned blocking portion. The first blocking portion 41 is relatively far away from the connection portion of the door body 2 with the second blocking portion 42. The first blocking portion 41 and the second blocking portion 42 are both located on the moving path of the lever 8 and can block the lever 8, and the second blocking portion 42 can be crossed by the lever 8.

[0055] like Figure 4 As shown, in this embodiment, the front side and the rear side of the dirt shielding plate 4 are bent upward to form the first stopper 41 and the second stopper 42. This sentence is described according to the opening direction of the door body 2.

[0056] like Figure 2 , 3As shown, the lever 8 includes a vertically extending rod body 81 and a bent section 82 formed by bending the lower end of the rod body 81 forward. The bowl basket 7 is provided with a positioning member 71. The rod body 81 passes through the positioning member 71 and can move up and down relative to the positioning member 71 under the action of external force. When no external force is applied to the lever 8, the lever 8 is positioned relative to the positioning member 71. The positioning member 71 is provided with a clamping groove 711 to clamp on the frame bar 72 of the bowl basket 7.

[0057] The front end of the bent section 82 can abut against the first stopper 41, and the connection between the lower end of the rod body 81 and the bent section 82 can abut against the second stopper 42. In this embodiment, the bent section 82 and the lower end of the rod body 81 are transitionally connected through the arc structure 83. In this way, when the lever 8 moves backward to abut against the second stopper 42, the arc structure 83 and the second stopper 42 are squeezed, because the dirt shielding plate 4 has reached the limit position and can no longer move, so it will force the lever 8 to move upward. The arc structure 83 is designed to facilitate the upward movement of the lever 8.

[0058] The side wall surface of the recess 22 adjacent to the bottom of the door body 2 is an inclined surface 220 inclined forward along the length direction of the door body 2, and the height of the inclined surface 220 is higher than the height of the second stopper 42. The arc structure 83 of the lever 8 interacts with the inclined surface 220, and because the door body 2 is fixed, the lever 8 is forced to move upward.

[0059] In this embodiment, there are two levers 8 arranged at intervals in the left and right directions, and the upper ends of the two levers 8 are connected by a connecting rod 84. The two levers 8 and the connecting rod 84 together constitute a toggle member 8a, and there is one toggle member 8a or at least two toggle members 8a arranged at intervals in the left and right directions. In this embodiment, there are two toggle members 8a, so that the dirt shielding plate 4 has multiple force points in the left and right directions and can move smoothly.

[0060] The working process of the cleaning machine of this embodiment is as follows:

[0061] The door body 2 is opened, and the bowl basket 7 is pulled forward a certain distance, the lever 8 is located outside the inner cavity 11, and then the lever 8 is pressed downward so that the bent section 82 contacts the dirt shielding plate 4 and is located between the first stopper 41 and the second stopper 42;

[0062] The bowl basket 7 is pulled forward until the free end of the bent section 82 abuts against the first stopper 41, and the bowl basket 7 is continued to be pulled forward completely out of the inner cavity 11. At this time, the lever 8 pushes the dirt shielding plate 4 to a position away from the connection portion of the door body 2 (i.e., the front of the door body 2). At this time, when oily tableware is placed in the bowl basket 7, the dripping oil will be caught by the dirt shielding plate 4 without contaminating the front of the door body 2. Figure 1 , 2 As shown;

[0063] After the tableware is placed, the bowl basket 7 is pushed back a certain distance, and the arc structure 83 contacts the second stop portion 42. Figure 7 , 8 As shown, as the bowl basket 7 is pushed backward, the dirt shielding plate 4 is moved to the rear area of ​​the door body 2. After the dirt shielding plate 4 reaches the limit position, the bowl basket 7 is pushed backward, and the arc structure 83 resists the second stopper 42, so that the lever 8 is pushed upward for a certain distance to pass the second stopper 42.

[0064] After the lever 8 passes the second stopper 42, it continues to push the basket 7 backward. The arc structure 83 interacts with the inclined surface 220 of the recessed portion 22 of the door body 2, so that the lever 8 is lifted as the basket 7 continues to move backward. Finally, the basket 7 and the lever 8 enter the inner cavity 11 as a whole, and the door body 2 is closed. At this time, the dirt shielding plate 4 is close to the connection portion of the door body 2 and is located in the lower space 112. Fig.10 As shown, full-cavity washing or half-cavity washing can be selected as needed, and the cleaning water can simultaneously enter the gap between the dirt shielding plate 4 and the rear wall of the door body 2 to clean the corresponding parts of the door body 2.

[0065] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
