Description

Technical Field

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

[0002] For a large number of built-in dishwashers, in order to improve the utilization rate of the internal space of the dishwasher, the "chopstick cage area" is usually extracted separately, and an additional cutlery tray is added to meet its loading needs. The cutlery tray is usually placed on the top layer (the top layer of the dishwasher's washing cavity). The space of the cutlery tray is relatively flat, and knives, forks, chopsticks, spoons, forks, soup spoons, etc. are placed on this layer of cutlery tray. In this way, the space of the upper and lower bowl baskets can be fully utilized for loading bowls and dishes.

[0003] As disclosed in the Chinese utility model patent with application number CN202120130779.4 (publication number CN214760975U), "A dishwasher and its inner tank assembly" is provided with an inner tank assembly, which includes a cutlery tray and a guide rail arranged on the inner wall of the inner tank, and a first pulley group connected to the guide rail is provided on the cutlery tray, so that the cutlery tray can be stored in the inner tank as the first pulley group moves on the guide rail.

[0004] The above-mentioned dishwasher sets the cutlery tray on the top layer of the inner tank of the dishwasher. Most dishwashers on the market currently adopt such an arrangement so that the cutlery can be rinsed through the spray arm arranged on the top of the inner tank. However, such a layout often sacrifices a certain degree of convenience, especially for a split-chamber dishwasher, as shown in the Chinese utility model patent disclosed in "A Dishwasher" with patent number CN202023348649.2 (publication number CN215383808U), when the number of cutlery 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 place the washed cutlery, and the lower space can be sprayed and washed separately, that is, the lower chamber washing, which not only makes full use of the box space, but also helps to save water, electricity and other energy; when there are more cutlery 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 wash the cutlery in the upper space and the lower space at the same time, that is, the whole chamber washing.

[0005] For this type of split-chamber dishwasher, if the lower-chamber washing mode is adopted, the cutlery tray is set on the top layer of the washing chamber, and the cutlery on the cutlery tray cannot be washed. It is necessary to separately equip the lower basket with a chopstick cage, which causes the placement space of other cutlery in the lower basket to be compressed, making it inconvenient to place a large number of cutlery in the lower basket, and the cutlery tray on the top layer also loses its function. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a tableware tray washing machine capable of adapting to a lower cavity washing mode in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a cleaning machine, comprising

[0008] A box body having a washing chamber with an open front side;

[0009] A partition assembly is transversely arranged in the washing chamber of the box body, and is used to separate the washing chamber of the box body into relatively independent upper space and lower space;

[0010] The lower bowl basket is arranged in the lower space;

[0011] It is characterized by that it also includes

[0012] The cutlery tray is arranged in the lower space and located above the lower bowl basket.

[0013] In order to make the washing machine also applicable to the situation where there are a large number of dishes to be washed, the partition assembly includes

[0014] A fixed plate, fixedly placed horizontally in the washing chamber and arranged close to the rear side of the box;

[0015] The movable plate is arranged to be movable relative to the fixed plate in the front-rear direction, and the movable plate cooperates with the fixed plate to separate the upper space from the lower space or connect the upper space with the lower space, and the movable plate is connected to the first driving mechanism. 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 place the washed dishes, and the lower space can be sprayed and washed separately, that is, lower cavity washing, which not only makes full use of the box space, but also helps to save water, electricity and other energy; 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 washes the dishes in the upper space and the lower space at the same time, that is, full cavity washing.

[0016] In order to enable the cutlery tray to hold cutlery of different sizes and to perform different cleaning modes according to the number of cutlery thereon in different cleaning modes of lower cavity washing or full cavity washing, the cutlery tray can move forward and backward under the action of a second driving mechanism. When the upper space and the lower space are separated, the cutlery tray can be located directly below the fixed plate or directly below the movable plate. When the upper space and the lower space are connected, the cutlery tray can be located directly below the movable plate or on the front side of the movable plate.

[0017] In order to reduce the cutlery tray from occupying too much lower space, resulting in the lower bowl basket being too limited in placement space, the cutlery tray is arranged adjacent to the partition assembly, so that the space above the lower bowl basket is larger and larger tableware, such as wine glasses, pots, etc., can be placed, while flat tableware such as chopsticks and spoons can be placed in the cutlery tray.

[0018] For a chamber-type washing machine, a spray arm located below the lower basket is provided in the lower space, and an upper basket is provided in the upper space, so that tableware can be stored in the upper basket and the tableware in the lower basket can be washed.

[0019] In order to improve the cleaning effect of the cutlery tray when the cutlery tray is located directly below the movable plate, a plurality of convex portions are provided at intervals on the lower wall surface of the movable plate. The convex portions can gather water droplets to drip onto the cutlery tray to clean the cutlery in the cutlery tray.

[0020] The second driving mechanism may be a motor and a push rod connected to the motor, the push rod pushes the cutlery tray, but the push rod needs to be designed to be longer in length to match the moving stroke of the cutlery tray, so preferably, the second driving mechanism includes a second motor mounted on the rear side wall of the box body, a second screw rod connected to the second motor drive, and a second nut arranged at the rear of the cutlery tray, the second screw rod extends in the front-to-back direction, and the second screw rod is threadedly connected to the second nut. In this way, the second screw rod can be designed to be shorter in length.

[0021] In order to prevent the cutlery tray from interfering with the second screw rod when moving, the cutlery tray is provided with an avoidance groove extending in the front-to-back direction for avoiding the second screw rod.

[0022] In order to limit the backward movement of the cutlery tray, a baffle that can abut against the front end of the second screw rod is provided in the avoidance groove at the front part of the cutlery tray. When the baffle abuts against the second screw rod, the second motor stops running after detecting the blocking current, thereby limiting the cutlery tray.

[0023] In order to make the fixed plate and the movable plate cooperate to separate or connect the upper space and the lower space, a gap is formed between the fixed plate and the box body for connecting the upper space and the lower space, and the movable plate can be slidably arranged on the fixed plate to open or close the gap.

[0024] In the above scheme, preferably, the movable plate is arranged below the fixed plate, and when the notch is open, the movable plate overlaps the lower side of the fixed plate, and the cutlery tray can be at least partially located directly below the notch; when the notch is closed, at least part of the movable plate intersects with the fixed plate and covers the notch. In this way, when the cutlery tray is located directly below the notch, since there is ample space above the cutlery tray, larger cutlery can be placed on the cutlery tray.

[0025] The first driving mechanism may be a motor and a push rod connected to the motor, the push rod pushes the moving plate, but the push rod needs to be designed to be longer to match the moving stroke of the moving plate, so the first driving mechanism includes a first motor mounted on the rear side wall of the box, a first screw rod connected to the first motor drive, and a first nut arranged at the rear of the moving plate, the first screw rod extends in the front-to-back direction, and the first screw rod is threadedly connected to the first nut. In this way, the length of the first screw rod can be designed to be shorter.

[0026] In order to improve the stability of the movement of the moving plate, a front mounting plate and a rear mounting plate are arranged in the box body along the front-to-back direction, the front mounting plate is located in front of the rear mounting plate, a first guide rail is arranged between the front mounting plate and the rear mounting plate, a first guide sleeve is arranged on the moving plate, the first guide rail is inserted into the first guide sleeve, and the first guide sleeve can slide along the first guide rail. The first guide rail not only plays a guiding role, but also plays a role in supporting the moving plate.

[0027] In order to improve the stability of the cutlery tray, a second guide rail is provided between the front mounting plate and the rear mounting plate, the second guide rail is located below the first guide rail, and a second guide sleeve is provided on the cutlery tray, the second guide rail is inserted into the second guide sleeve, and the second guide sleeve can slide along the second guide rail. The second guide rail not only plays a guiding role, but also plays a role in supporting the cutlery tray.

[0028] In order to further improve the stability of the movement of the movable plate and the cutlery tray, the front mounting plate and the rear mounting plate are provided on the left and right sides of the fixed plate, and correspondingly, there are two first guide rails and two second guide rails.

[0029] In order to position the chopsticks placed on the tableware tray, a shelf plate is provided in the tableware tray, and a plurality of grooves are sequentially provided on the upper surface of the shelf plate along its length direction. The head of each chopstick can be placed in the groove to limit the position of the chopsticks.

[0030] Compared with the prior art, the advantages of the present invention are as follows: the present invention arranges the cutlery tray below the partition assembly, so that when the lower cavity is washed, the water sprayed by the spray arm in the lower space can also clean the cutlery in the cutlery tray, solving the problem that the existing cutlery tray is arranged at the top of the washing cavity and cannot be cleaned when the lower cavity is washed; and the cutlery tray is located above the lower bowl basket and will not interfere with the lower bowl basket. Large-sized tableware such as bowls, dishes, and pots can be placed in the lower bowl basket, and small-sized tableware such as chopsticks and soup spoons can be placed in the cutlery tray.

[0041] like Figures 1 to 9 As shown, the cleaning machine of this preferred embodiment includes a housing 1, a partition assembly, a cutlery tray 6, a spray arm 7, an upper bowl basket 4, a lower bowl basket 5, etc.

[0042] like Figure 1 As shown, the housing 1 has a washing chamber 11, and a partition assembly is disposed in the washing chamber 11 of the housing 1. The partition assembly can separate the washing chamber 11 of the housing 1 into a relatively independent upper space 11a and a lower space 11b.

[0043] like Figure 1 , 2 As shown in Figures 3, the partition assembly includes a fixed plate 2 and a movable plate 3. The fixed plate 2 is horizontally placed in the middle of the box body 1 and fixedly connected to the inner wall of the box body 1. The movable plate 3 is arranged to be movable relative to the fixed plate 2 along the front-to-back direction, and is used to cooperate with the fixed plate 2 to separate the upper space 11a from the lower space 11b or connect the upper space 11a with the lower space 11b.

[0044] In this embodiment, the fixed plate 2 is arranged near the rear side of the box body 1, and a gap 11c is formed between the fixed plate 2 and the front side wall of the box body 1 for connecting the upper space 11a and the lower space 11b. The movable plate 3 is arranged below the fixed plate 2. The movable plate 3 can slide forward and backward on the fixed plate 2 and is used to open or close the gap 11c. Figure 8 , 9 As shown, when the notch 11c is opened, the movable plate 3 overlaps the lower side of the fixed plate 2; Figure 1 As shown, when the notch 11c is closed, at least a portion of the movable plate 3 is interlaced with the fixed plate 2 and covers the notch 11c. This is a prior art and will not be described in detail.

[0045] The moving plate 3 is connected to the first driving mechanism. Figure 3 As shown, the first driving mechanism includes a first motor (not shown) mounted on the rear side wall of the box body 1, a first screw rod 31 drivingly connected to the first motor, and a first nut 32 arranged at the rear of the moving plate 3. The first screw rod 31 extends in the front-to-back direction, and the first screw rod 31 is threadedly connected to the first nut 32. When the first motor works, it drives the first screw rod 31 to rotate, and the first nut 32 moves along the first screw rod 31, thereby driving the moving plate 3 to move forward and backward.

[0046] like Figure 1 As shown, an upper bowl basket 4 is provided in the upper space 11a, a lower bowl basket 5 and a cutlery tray 6 are provided in the lower space 11b, a spray arm 7 is provided in the lower space 11b and located at the bottom of the lower bowl basket 5, and the spray arm 7 can adopt an existing structure.

[0047] Tableware can be stored in the upper basket 4, and the tableware in the lower basket 5 can be washed. In order to reduce the tableware tray 6 from occupying too much of the lower space 11b, which would result in the lower basket 5 being too limited in space, the tableware tray 6 is located above the lower basket 5 and is arranged adjacent to the partition assembly. In this way, the space above the lower basket 5 is larger, and larger tableware, such as wine glasses and pots, can be placed. Flat tableware, such as chopsticks and spoons, can be placed in the tableware tray 6. Figure 5 As shown, a shelf plate 61 is provided in the cutlery tray 6, and a plurality of grooves 611 are sequentially provided on the upper surface of the shelf plate 61 along its length direction. The head of each chopstick can be placed in the groove 611 to limit the position of the chopstick.

[0048] like Figure 3 , 6As shown, the cutlery tray 6 can move forward and backward under the action of the second driving mechanism, which includes a second motor installed on the rear side wall of the box body 1, a second screw rod 62 connected to the second motor, and a second nut 63 provided at the rear of the cutlery tray 6. The second screw rod 62 extends in the front-to-back direction, and the second screw rod 62 is threadedly connected to the second nut 63. The second motor works to drive the second screw rod 62 to rotate, and the second nut 63 moves along the second screw rod 62, thereby driving the cutlery tray 6 to move forward and backward. The cutlery tray 6 is provided with an avoidance groove 64 extending in the front-to-back direction to avoid the second screw rod 62, so as to prevent the cutlery tray 6 from interfering with the second screw rod 62 when moving.

[0049] In addition, a baffle 65 is provided in the avoidance groove 64 at the front of the cutlery tray 6, and the baffle 65 can abut against the front end of the second screw rod 62. When the baffle 65 abuts against the second screw rod 62, the second motor stops running after detecting the blocking current, thereby limiting the cutlery tray 6.

[0050] A front mounting plate 21 and a rear mounting plate 22 are provided in the box body 1 along the front-to-back direction. In this embodiment, the front mounting plate 21 and the rear mounting plate 22 are both connected to the fixed plate 2, and the front mounting plate 21 is located in front of the rear mounting plate 22. A first guide rail 23 and a second guide rail 24 are provided between the front mounting plate 21 and the rear mounting plate 22, and the second guide rail 24 is located below the first guide rail 23. A first guide sleeve 33 is provided on the movable plate 3, and the first guide rail 23 is inserted into the first guide sleeve 33, and the first guide sleeve 33 can slide along the first guide rail 23. A second guide sleeve 66 is provided on the cutlery tray 6, and the second guide sleeve 66 is inserted into the second guide sleeve 66, and the second guide sleeve 66 can slide along the second guide rail 24. The front mounting plate 21 and the rear mounting plate 22 are provided on both the left and right sides of the fixed plate 2, and correspondingly, there are two first guide rails 23 and two second guide rails 24.

[0051] When the upper space 11a and the lower space 11b are separated, the cutlery tray 6 can be located directly below the fixed plate 2 or directly below the movable plate 3. When the upper space 11a and the lower space 11b are connected, the cutlery tray 6 can be located directly below the movable plate 3 or in front of the movable plate 3. When the cutlery tray 6 is located in front of the movable plate 3, at least part of the cutlery tray 6 is located directly below the notch 11c. A plurality of convex portions 30 are provided at intervals on the lower wall surface of the movable plate 3. The convex portions 30 can gather water droplets to drip onto the cutlery tray 6 to wash the cutlery in the cutlery tray 6.

[0052] Specifically, the cleaning mode of the cleaning machine of this embodiment is as follows:

[0053] Mode 1:

[0054] like Figure 1As shown, the upper space 11a and the lower space 11b are separated, and the cutlery tray 6 moves forward to the extreme position. At this time, the cutlery tray 6 is located directly below the movable plate 3. The cutlery in the lower bowl basket 5 is mainly washed by the water flow sprayed by the spray arm 7. The cutlery in the cutlery tray 6 is mainly washed by two parts of water flow: first, the water flow sprayed by the spray arm 7 passes through the cutlery in the lower bowl basket 5 and splashes onto the cutlery in the cutlery tray 6; second, the water droplets gathered by the convex part 30 on the movable plate 3 drip onto the cutlery in the cutlery tray 6. In this way, the lower cavity washing mode realizes energy saving and water saving, and the cutlery in the cutlery tray 6 is washed by two water flows. There are a large number of cutlery in the cutlery tray 6, and the washing effect can also be guaranteed.

[0055] Mode 2:

[0056] like Figure 7 As shown, the upper space 11a and the lower space 11b are separated, and the cutlery tray 6 moves backward to the extreme position. At this time, the cutlery tray 6 is located directly below the fixed plate 2. This mode is suitable for washing fewer dishes, a small amount of chopsticks, knives, forks, spoons and other tableware. Moreover, since the cutlery tray 6 moves backward, there is ample space above the lower bowl basket 5 corresponding to the notch 11c, and kitchen utensils with a larger height, such as a wok, can be placed on the lower bowl basket 5.

[0057] Mode 3:

[0058] like Figure 8 As shown, the upper space 11a and the lower space 11b are connected, and the cutlery tray 6 moves backward to the extreme position. At this time, the cutlery tray 6 is located directly below the movable plate 3, and a full-cavity washing mode is performed. In this mode, the water flow system has smooth and fast return water, a large amount of water, and the strongest washing capacity, which can meet the washing needs of all dishes under the rated set capacity; the cutlery tray 6 is continuously "rinsed" by the falling water drops from the upper convex part 30 of the upper movable plate 3, which can meet the washing needs of more chopsticks, knives, forks, spoons and other tableware.

[0059] Mode 4:

[0060] like Fig. 9 As shown, the upper space 11a and the lower space 11b are connected, and the cutlery tray 6 moves forward to the extreme position. At this time, the cutlery tray 6 is located on the front side of the movable plate 3 and directly below the notch 11c, and the full-cavity washing mode is performed. In this mode, due to the forward pushing of the cutlery tray 6, the space above the cutlery tray 6 is expanded, so some higher utensils can be placed, such as a larger colander, a sink water filter, a steaming rack, etc., to meet personalized tableware washing needs.

[0061] As can be seen from the above, the washing machine of this embodiment can realize four different customer usage scenarios and meet the personalized washing needs of different quantities and types of tableware.

[0062] 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. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0063] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part.
