Description

Technical Field

[0001] This application belongs to the technical field of kitchen utensils, and in particular relates to a cleaning machine and a sink-type cleaning device. Background Technology

[0002] A sink-type cleaning machine, or simply a cleaning machine, is a household appliance that integrates cleaning functions around the kitchen sink. It is usually installed side by side with the sink on the kitchen countertop.

[0003] Currently, most conventional cleaning machines on the market use a cylindrical structure for their cleaning housing, extending vertically downwards to below the sink. The cleaning chamber typically has two sets of spray arms arranged vertically at intervals, relying on the rotation of these arms to cover the cleaning chamber. Limited by the sink space, the cleaning space of such machines is often limited to vertical downwards, resulting in a vertically extending cylindrical shape with a relatively uniform cross-sectional area, forming a straight, regular shape. As users' demands for cleaning capacity increase, existing technologies generally employ two methods to improve the capacity of these machines: firstly, increasing the vertical dimension of the cleaning housing, i.e., deepening it; however, this is limited by cabinet depth and operational feasibility, resulting in very limited room for deepening; secondly, increasing the horizontal dimension of the cleaning housing. However, the conventional method encroaches on the sink's volume, significantly reducing the user experience of a standard sink. Furthermore, the expanded chamber created by horizontal expansion is difficult to be impacted by the water flow from the spray arms, resulting in cleaning dead zones. Therefore, it is necessary to develop and design a cleaning machine with a new structural form. Summary of the Invention

[0004] In view of this, it is necessary to provide a cleaning machine and a water tank type cleaning device that can solve the above-mentioned technical problems. It overcomes the conventional thinking that cleaning machines must adopt a structure that is larger at the top and smaller at the bottom or with equal diameters at the top and bottom. It has an original design that expands the capacity by extending the lower part of the cleaning machine outward, thereby effectively utilizing the empty space under the water tank to increase the cleaning capacity.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A cleaning machine, the cleaning machine comprising:

[0007] A cleaning housing, the cleaning housing enclosing to form a main cleaning chamber and at least one expansion chamber, the at least one expansion chamber being located on one side of the main cleaning chamber in a first direction and communicating with the main cleaning chamber;

[0008] A spray assembly, comprising a first spray arm and a second spray arm, wherein the first spray arm and the second spray arm are spaced apart along a second direction, and the second direction forms a preset angle with the first direction;

[0009] Wherein, the first spray arm has a first spray area that covers at least a portion of the expansion chamber; and / or, the second spray arm has a second spray area that covers at least a portion of the expansion chamber.

[0010] It is understood that by providing at least one expansion chamber within the cleaning housing that communicates with and is located on one side of the main cleaning chamber, the cleaning machine, when used with a water tank, can arrange the expansion chamber at least directly below the water tank, thereby utilizing the previously unused space below the water tank to expand the cleaning housing. At the same time, since the first spray area of ​​the first spray arm and / or the second spray area of ​​the second spray arm can cover at least part of the expansion chamber, the cleaning machine can clean and cover the expansion chamber during operation, thus enabling the cleaning machine to meet the needs of large-capacity cleaning.

[0011] In one embodiment, the size of the expansion chamber in the first direction is set as L1, and the size of the main cleaning chamber in the first direction is set as L2, and L1 and L2 satisfy 2%≤L1 / L2≤80%.

[0012] Understandably, by setting the size ratio between the expansion chamber and the main cleaning chamber in the first direction between 2% and 80%, it can ensure the placement of tableware and facilitate the smooth loading and unloading of dish racks, avoiding the operational inconvenience caused by an excessively large expansion chamber. On the other hand, it can effectively expand the cleaning shell within a reasonable range, making full use of the unused space under the sink and avoiding the defects of insufficient expansion gain and low space utilization caused by an excessively small size ratio.

[0013] In one embodiment, 10% ≤ L1 / L2 ≤ 50%.

[0014] In one embodiment, the first spray arm is rotatably mounted in the main cleaning chamber; and the first spray arm is located above the expansion chamber in the second direction.

[0015] In one embodiment, the first spray arm is provided with a lower water outlet, and the first spray arm can spray water into the expansion chamber through the lower water outlet.

[0016] It is understandable that by arranging a lower water outlet on the first spray arm that sprays water towards the expansion chamber, the first spray arm can directly spray water onto the expansion chamber through the lower water outlet during the rotation spraying process. This expands the cleaning coverage of the expansion chamber when the first spray arm is working, and helps to improve the cleaning effect of the washing machine when cleaning tableware in the expansion chamber.

[0017] In one embodiment, the lower water outlet includes a first lower water outlet and a second lower water outlet, the first lower water outlet and the second lower water outlet being located at both ends of the first spray arm in the first direction.

[0018] It is understandable that by arranging a first lower water outlet and a second lower water outlet at both ends of the first spray arm in the first direction, the first spray arm can alternately spray water onto the expansion chamber through the first lower water outlet and the second lower water outlet during one rotation, thereby improving the cleaning effect of the washing machine when cleaning tableware in the expansion chamber.

[0019] In one embodiment, the water outlet direction of the first lower outlet forms an angle A with the first direction, and the angle A satisfies 10°≤A≤30°.

[0020] In one embodiment, the water outlet direction of the second lower outlet forms an angle B with the first direction, and the angle B satisfies 40°≤B≤70°.

[0021] It is understandable that by spraying water onto the expansion chamber through the first and second lower water outlets at different tilt angles, the cleaning coverage of the expansion chamber by the first spray arm can be further expanded, thereby further improving the cleaning effect of the washing machine when cleaning tableware in the expansion chamber.

[0022] In one embodiment, the second spray arm is rotatably mounted inside the cleaning housing; and a portion of the second spray arm is capable of extending into the expansion chamber.

[0023] The second spray arm is provided with an upper water outlet, and the second spray arm can spray water into the expansion chamber through the upper water outlet.

[0024] It is understandable that by arranging an upper water outlet on the second spray arm that sprays water towards the expansion chamber, the second spray arm can directly spray water onto the expansion chamber through the upper water outlet during the rotation spraying process, thereby expanding the cleaning coverage of the expansion chamber when the second spray arm is working, which helps to improve the cleaning effect of the washing machine when cleaning tableware in the expansion chamber.

[0025] In one embodiment, at least one sub-spray disc is rotatably connected to the second spray arm, the sub-spray disc being disposed at the end position of the second spray arm in the first direction;

[0026] The sub-spray disc is provided with a plurality of upper water outlets at intervals along its circumferential direction.

[0027] Understandably, by arranging sub-spray discs with multiple upper water outlets on the second spray arm, the second spray arm can simultaneously spray water onto the expansion chamber using multiple rotating upper water outlets during operation. This further expands the cleaning coverage of the expansion chamber by the second spray arm during operation, thereby further improving the cleaning effect of the washing machine when cleaning tableware in the expansion chamber.

[0028] In one embodiment, the number of expansion chambers is configured to be one;

[0029] Along the first direction, the second spray arm is positioned closer to the expansion chamber than the rotation axis of the first spray arm.

[0030] It is understandable that by arranging the second spray arm at an angle relative to the first spray arm toward the expansion chamber in the first direction, favorable conditions are created for the second spray area of ​​the second spray arm to cover the expansion chamber.

[0031] In one embodiment, the preset angle between the first direction and the second direction is set to C, and the preset angle C satisfies 70°≤C≤110°.

[0032] In one embodiment, the first direction is configured as the lateral direction of the cleaning housing; and the second direction is configured as the vertical direction of the cleaning housing.

[0033] In one embodiment, the washing machine further includes a dish rack installed in the main washing chamber;

[0034] The second spray arm is located below the bowl rack in the second direction, and the first spray arm is located above the expansion chamber in the second direction.

[0035] Understandably, by arranging side racks connected to the dish racks within the expanded chamber, the washing machine can use the side racks to support tableware, thus meeting the needs of large-capacity washing.

[0036] In one embodiment, the washing machine further includes a side frame and a dish rack, the side frame being at least partially installed in the expansion chamber; the dish rack also has a side opening located on the side of the dish rack facing the side frame in the first direction; the dish rack encloses to form an accommodating space, the accommodating space communicating with the expansion chamber through the side opening.

[0037] Understandably, by setting a side opening on the side of the dish rack facing the expanded chamber, the washing machine can use the side rack in conjunction with the dish rack to support the tableware, thus further meeting the needs of large-capacity washing.

[0038] In one embodiment, the washing machine further includes a side frame disposed near the side opening, the side frame being located within the expansion chamber at least in the operating state, for carrying tableware that extends into or is placed within the expansion chamber.

[0039] In one embodiment, the washing machine further includes a dish rack and a side rack, the side rack being movably mounted on the side of the dish rack near the expansion chamber; the side rack has an extended position and a retracted position, when the side rack is in the extended position, the side rack extends into the expansion chamber; when the side rack is in the retracted position, the side rack is retracted into the side or interior of the dish rack.

[0040] Understandably, by folding the side rack to the dish rack and setting up an unfolded position and a storage position for it, the washing machine can use the unfolded side rack to carry tableware. This allows for the use of the expanded chamber to hold tableware, meeting the needs of large-capacity washing. Alternatively, the side rack can be switched to the storage position, allowing it to be removed from the main washing chamber along with the dish rack, thus adapting the washing machine to different usage scenarios.

[0041] In one embodiment, the washing machine further includes a dish rack and a shelf, the shelf being foldably connected to the dish rack; and both the shelf and the dish rack are installed in the main washing chamber.

[0042] When the shelf is positioned above the bowl rack in the second direction, the first spray area of ​​the first spray arm can cover the area of ​​the shelf above the second direction.

[0043] Understandably, by folding the rack above the dish rack in the second direction, the washing machine can use the rack to hold the tableware and use the first spray arm to spray water for cleaning, thus meeting the needs of large-capacity washing.

[0044] This application also provides a water tank type cleaning device, including a water tank and the cleaning machine described above;

[0045] The water tank is fixedly connected to the cleaning housing, and the expansion chamber is at least partially located below the water tank in the second direction.

[0046] Due to the application of the above solution, this application has the following advantages compared with the prior art:

[0047] The cleaning machine and water tank type cleaning device claimed in this application, by providing at least one expansion chamber in the cleaning housing that communicates with and is located on one side of the main cleaning chamber, allows the cleaning machine to be arranged at least directly below the water tank when used with the water tank, thereby utilizing the originally unused space below the water tank to expand the cleaning housing; at the same time, since the first spray area of ​​the first spray arm and / or the second spray area of ​​the second spray arm can cover at least part of the expansion chamber, the cleaning machine can clean and cover the expansion chamber when it is working, thereby enabling the cleaning machine to meet the needs of large-capacity cleaning.

[0064] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0069] like Figure 1 As shown, the cleaning machine 100 claimed in this application is used in a water tank type cleaning device 1000 and is used in conjunction with a water tank 200.

[0070] like Figures 2 to 10As shown, the cleaning machine 100 provided in this application includes a cleaning housing 10 and a spray assembly 20 installed in the cleaning housing 10. The cleaning housing 10 encloses a main cleaning chamber 101 and at least one expansion chamber 102. The at least one expansion chamber 102 is located on one side of the main cleaning chamber 101 in a first direction X and communicates with the main cleaning chamber 101. The spray assembly 20 includes a first spray arm 21 and a second spray arm 22. The first spray arm 21 and the second spray arm 22 are distributed at intervals along a second direction Y, and the second direction Y forms a preset angle with the first direction X. The first spray arm 21 forms a first spray area (not shown), which covers at least part of the expansion chamber 102. And / or, the second spray arm 22 forms a second spray area (not shown), which covers at least part of the expansion chamber 102. It should be noted that the first spray area mentioned above specifically refers to the water spray coverage area formed by the first spray arm 21 spraying water when it is working; similarly, the second spray area mentioned above specifically refers to the water spray coverage area formed by the second spray arm 22 spraying water when it is working.

[0071] Here, the number of expansion chambers 102 is set to one, and when the cleaning machine 100 is used in conjunction with the water tank 200, the expansion chamber 102 is at least partially located directly below the water tank 200. Of course, this is not the only possibility. For those skilled in the art, the number of expansion chambers 102 can also be set to two, three, or even more depending on the actual design requirements, as long as it is ensured that at least part of one expansion chamber 102 is located directly below the water tank 200. This will not be elaborated further here.

[0072] As can be seen from the above, the cleaning machine 100 of this application, by providing at least one expansion chamber 102 in the cleaning housing 10 that communicates with the main cleaning chamber 101 and is located on one side therein, enables the cleaning machine 100 to arrange the expansion chamber 102 at least directly below the water tank 200 when used in conjunction with the water tank 200, thereby utilizing the originally unused space below the water tank 200 to expand the capacity of the cleaning housing 10; at the same time, since the first spray area of ​​the first spray arm 21 and / or the second spray area of ​​the second spray arm 22 can cover at least part of the expansion chamber 102, the cleaning machine 100 can clean and cover the expansion chamber 102 when it is working, thereby enabling the cleaning machine 100 to meet the usage requirements of large-capacity cleaning.

[0073] In this application, the preset angle formed between the second direction Y and the first direction X is set as C, and the preset angle C satisfies 70°≤C≤110°. The value of the preset angle C can be set to 70°, 80°, 88°, 90°, 95°, 100°, or 110° according to actual design requirements. Specifically, the second direction Y is the vertical direction of the cleaning machine 100, and the angle between the first direction X and the second direction Y can be achieved by adjusting the arrangement direction of the expansion chamber 102 relative to the main cleaning chamber 101, which will not be elaborated here.

[0074] Here, the first direction X is configured as the lateral direction of the cleaning housing 10; and the second direction Y is configured as the vertical direction of the cleaning housing 10.

[0075] In this application, the dimension of the expansion chamber 102 in the first direction X is set as L1, and the dimension of the main cleaning chamber 101 in the first direction X is set as L2, and L1 and L2 satisfy 2%≤L1 / L2≤80%. This ensures the placement of tableware 110 and facilitates the smooth loading and unloading of the dish rack 32, avoiding operational inconvenience caused by an excessively large proportion of the expansion chamber 102. Furthermore, it effectively expands the internal space of the cleaning housing 10 within a reasonable range, fully utilizing the unused space below the sink 200 and avoiding the defects of insufficient expansion gain and low space utilization due to an excessively small proportion. It should be noted that L1 is the maximum dimension of the expansion chamber 102 in the first direction X, specifically the dimension of the expansion chamber 102 at its bottom position in the second direction Y; while L2 is the minimum dimension of the main cleaning chamber 101 in the first direction X, specifically the dimension of the main cleaning chamber 101 at its top position in the second direction Y.

[0076] Preferably, 10%≤L1 / L2≤50%, wherein the parameters of L1 / L2 can be set to 10%, 20%, 26%, 30%, 40%, 50%, etc. according to actual design requirements, which will not be elaborated here.

[0077] like Figure 3 , Figure 4 As shown, in the first embodiment of this application, the cleaning housing 10 includes an upper cylinder 11 and a lower cylinder 12. The upper cylinder 11 is positioned above the lower cylinder 12 in the second direction Y. Specifically, the upper cylinder 11 can be mounted on the cover plate 121 of the lower cylinder 12. It should be noted that the connection between the cover plate 121 and the lower cylinder 12 and the upper cylinder 11 can be achieved by conventional methods such as welding or flange interlocking, which will not be elaborated here.

[0078] The lower cylinder 12 protrudes relative to the upper cylinder 11 along the first direction X; and the protrusion of the lower cylinder 12 relative to the upper cylinder 11 is used to enclose and form the expansion chamber 102 of the cleaning housing 10, specifically the expansion chamber 102 can be square; and the part of the lower cylinder 12 protruding relative to the upper cylinder 11 is located directly below the water tank 200; at the same time, the remaining parts of the upper cylinder 11 and the lower cylinder 12 together enclose and form the main cleaning chamber 101 of the cleaning housing 10.

[0079] like Figure 5 , Figure 6 As shown, in the second embodiment of this application, the cleaning housing 10 includes a main housing 13 and a side housing 14. The side housing 14 is located on one side of the main housing 13 in the first direction X, and is connected and communicates with the main housing 13; and the side housing 14 is arranged directly below the water tank 200. This allows the main housing 13 to enclose and form the main cleaning chamber 101 of the cleaning housing 10, while the side housing 14 encloses and forms the expansion chamber 102 of the cleaning housing 10.

[0080] like Figure 7 As shown, in the third embodiment of this application, the cleaning housing 10 includes a first cylinder 15, a second cylinder 16, and a third cylinder 17 connected and communicating sequentially from top to bottom along the second direction Y. The second cylinder 16 has a small-diameter portion 161 and a large-diameter portion 162 arranged opposite to each other. The large-diameter portion 162 protrudes outward relative to the small-diameter portion 161 in the first direction X, thereby allowing the large-diameter portion 162 to be partially located directly below the water tank 200.

[0081] The diameter of the small-diameter section 161 is equal to the diameter of the first cylinder 15, and the diameter of the large-diameter section 162 is equal to the diameter of the third cylinder 17. Furthermore, the first cylinder 15, a portion of the second cylinder 16, and a portion of the third cylinder 17 together enclose the main cleaning chamber 101 of the cleaning housing 10, while the remaining portion of the second cylinder 16 and the remaining portion of the third cylinder together enclose the expansion chamber 102 of the cleaning housing 10.

[0082] like Figure 8 As shown, in the fourth embodiment of this application, the cleaning housing 10 includes an upper housing 18 and a lower housing 19 that are sequentially connected and communicate with each other along the second direction Y. The diameter of the upper housing 18 gradually increases from top to bottom along the second direction Y, and the larger portion of the upper housing 18 is located directly below the water tank 200; the diameter of the lower housing 19 is equal to the maximum diameter of the upper housing 18.

[0083] like Figure 2 , Figure 9 and Figure 10As shown, in this application, the first spray arm 21 is rotatably mounted within the main cleaning chamber 101; and the first spray arm 21 is located above the expansion chamber 102 in the second direction Y. This allows the first spray arm 21 to spray water in a rotating manner. It should be noted that the supporting structure for supplying water to the first spray arm 21 in the cleaning machine 100, as well as the specific method by which the first spray arm 21 achieves rotating spraying, can all adopt conventional designs in the prior art, and will not be elaborated here.

[0084] In this embodiment, the first spray arm 21 is provided with a lower water outlet 211, and the water outlet 211 is directed toward the expansion chamber 102. The first spray arm 21 can spray water toward the expansion chamber 102 through the lower water outlet 211. This design allows the first spray arm 21 to spray water directly onto the expansion chamber 102 through the lower water outlet 211 during the rotation spraying process, thereby expanding the cleaning coverage of the expansion chamber 102 when the first spray arm 21 is working. This helps to improve the cleaning effect of the washing machine 100 when cleaning the tableware 110 in the expansion chamber 102.

[0085] Furthermore, the lower water outlet 211 includes a first lower water outlet 2111 and a second lower water outlet 2112, which are located at both ends of the first spray arm 21 in the first direction X. With this design, during one rotation of the first spray arm 21, water can be alternately sprayed onto the expansion chamber 102 by the first lower water outlet 2111 and the second lower water outlet 2112. This improves the water spraying efficiency of the first spray arm 21 on the expansion chamber 102 during operation, thereby further improving the cleaning effect of the first spray arm 21 on the tableware 110 inside the expansion chamber 102.

[0086] Here, the number of the first lower outlet 2111 and the number of the second lower outlet 2112 are both set to one. Of course, it is not limited to this. For those skilled in the art, the number of the first lower outlet 2111 and / or the number of the second lower outlet 2112 can also be two, three, or even more, which will not be elaborated here.

[0087] Specifically, the water outlet direction of the first lower outlet 2111 forms an angle A with the first direction X, and the angle A satisfies 10°≤A≤30°; and / or, the water outlet direction of the second lower outlet 2112 forms an angle B with the first direction X, and the angle B satisfies 40°≤B≤70°. This design allows the first lower outlet 2111 and the second lower outlet 2112 to spray water onto the expansion chamber 102 from two different directions when the first spray arm 21 is working. This further expands the cleaning coverage area of ​​the expansion chamber 102 when the first spray arm 21 is working, thereby further improving the cleaning effect of the washing machine 100 when cleaning the tableware 110 in the expansion chamber 102.

[0088] Preferably, 10°≤A≤30°, and 40°≤B≤70°. Here, the included angle A can be set to 10°, 15°, 20°, or 30°, etc., according to actual design needs; simultaneously, the included angle B can be set to 40°, 45°, 56°, 60°, or 70°, etc. It should be noted that during the operation of the first spray arm 21, the final spray direction of water from the first lower outlet 2111 and the second lower outlet 2112 onto the expansion chamber 102 is also affected by the water pressure supplied by the first spray arm 21, which will not be elaborated upon here.

[0089] like Figure 2 , Figure 9 As shown in this application, the second spray arm 22 is rotatably mounted inside the cleaning housing 10; and part of the second spray arm 22 can extend into the expansion chamber 102, so that the second spray arm 22 sprays water in a rotating spray manner. It should be noted that the supporting structure for supplying water to the second spray arm 22 in the cleaning machine 100 and the specific method by which the second spray arm 22 achieves rotating spraying can all adopt conventional designs in the prior art, and will not be elaborated here.

[0090] Here, the number of expansion chambers 102 is configured to be one; along the first direction, the second spray arm 22 is positioned closer to the expansion chamber 102 than the rotation axis of the first spray arm 21. That is, by arranging the second spray arm 22 at an angle relative to the first spray arm 21 toward the expansion chamber in the first direction X, favorable conditions are created for the second spray area of ​​the second spray arm 22 to cover the expansion chamber 102. It should be noted that the other structural components of the spray assembly 20 and how it is assembled and connected with the first spray arm 21 and the second spray arm 22 and supplied with water can all adopt conventional methods of the prior art, and will not be elaborated here.

[0091] In this embodiment, the second spray arm 22 is provided with an upper water outlet 221, the water outlet 221 is directed toward the expansion chamber 102, and the second spray arm 22 can spray water toward the expansion chamber 102 through the upper water outlet 221. This design allows the second spray arm 22 to directly spray water onto the expansion chamber 102 via the upper water outlet 221 during rotational spraying, thereby expanding the cleaning coverage of the expansion chamber 102 when the second spray arm 22 is working, and helping to improve the cleaning effect of the washing machine 100 when cleaning the tableware 110 in the expansion chamber 102.

[0092] Furthermore, at least one sub-spray disc 220 is rotatably connected to the second spray arm 22, and the sub-spray disc 220 is disposed at both ends of the second spray arm 22 in the first direction X; wherein, each sub-spray disc 220 is provided with multiple upper water outlets 221 at intervals along its circumferential direction. This design allows the second spray arm 22 to spray water onto the expansion chamber 102 simultaneously with the multiple rotating upper water outlets 221 when it is working, which can further expand the cleaning coverage of the expansion chamber 102 when the second spray arm 22 is working, thereby further improving the cleaning effect of the washing machine 100 when cleaning the tableware 110 in the expansion chamber 102.

[0093] Here, the number of sub-spray discs 220 can be set to one or two, preferably two. The number of upper water outlets 221 arranged on each sub-spray disc 220 can be two, three, four, or even more. It should be noted that the assembly method of the sub-spray discs 220 on the second spray arm 22 and the principle of the second spray arm 22 supplying water to the sub-spray discs 220 can both adopt conventional methods in the prior art, and will not be elaborated upon here.

[0094] like Figure 11 , Figure 13 and Figure 14 As shown, in this application, the washing machine 100 also includes a dish rack 32, which is installed inside the main washing chamber 101. This allows the washing machine 100 to use the side rack 31 to support the tableware 110, thus meeting the needs of large-capacity washing.

[0095] The second spray arm 22 is located below the bowl rack 32 in the second direction Y, and the first spray arm 21 is located above the expansion chamber 102 in the second direction Y.

[0096] like Figure 11 , Figure 13 and Figure 14As shown, the dish rack 32 has an opening 321, allowing the user to place tableware 110 into the dish rack 32 through the opening 321. Furthermore, the dish rack 32 also has a side opening 322, located on the side of the dish rack 32 facing the side frame 31 in the first direction X. The dish rack 32 encloses and forms a receiving space 320, which communicates with the expansion chamber 102 through the side opening 322. Thus, the washing machine 100 can use the side frame 31 in conjunction with the dish rack 32 to support the tableware 110. Specifically, various bowls and plates can be stacked from the dish rack 32 onto the side frame 31, or pots and pans can be placed on the side frame 31, further meeting the needs of large-capacity washing.

[0097] The side frame 31 of the washing machine 100 also includes a side frame 31 disposed near the side opening 322. The side frame 31 is located in the expansion chamber 102 at least in the working state and is used to carry tableware 110 that extends into or is placed in the expansion chamber 102.

[0098] Specifically, the side frame 31 is movably installed inside the washing housing 10. The side frame 31 has an unfolded position and a retracted position. When the side frame 31 is in the unfolded position, it unfolds into the expansion chamber 102. When the side frame 31 is in the retracted position, it is installed in the accommodating space 320. This allows the washing machine 100 to use the side frame 31 in the unfolded position to carry tableware 110, which is beneficial for using the expansion chamber 102 to place tableware to meet the needs of large-capacity washing. Alternatively, the side frame 31 can be switched to the retracted position, allowing it to be removed from the main washing chamber 101 along with the dish rack 32, thus adapting the washing machine 100 to different usage scenarios.

[0099] Here, the side bracket 31 is foldably connected to the dish rack 32. Specifically, as shown... Figure 12 As shown, the side frame 31 is provided with multiple spaced hooks 311, while the bowl rack 32 is provided with corresponding spaced shafts 323 and support rods 324. The side frame 31 hooks the shafts 323 with the hooks 311, and the support rods 324 abut against and limit the movement of the side frame 31, thus achieving a stable assembly connection between the side frame 31 and the bowl rack 32 when in the unfolded position. At the same time, the side frame 31 can rotate about 180° toward the bowl rack 32 until it is fully installed in the receiving space 320 of the bowl rack 32 and supported by the bottom of the bowl rack 32.

[0100] like Figure 11 , Figure 13 and Figure 14As shown, in this application, the washing machine 100 also includes a shelf 33, which is rotatably connected to the dish rack 32. Both the shelf 33 and the dish rack 32 are installed in the main washing chamber 101. When the shelf 33 is positioned above the dish rack 32 in the second direction Y, the shelf 33 can be placed flat above the opening 321 of the dish rack 32 and supported by the dish rack 32. Furthermore, the first spray area of ​​the first spray arm 21 can cover the area above the shelf 33 in the second direction Y. In this way, the washing machine 100 can use the shelf 33 to carry the tableware 110 and use the first spray arm 21 to spray water for cleaning, thus meeting the needs of large-capacity washing. It should be noted that the specific structure of the shelf 33 and its assembly and connection method with the dish rack 32 can all adopt conventional technical means in the art, and will not be elaborated here.

[0101] like Figure 1 As shown, this application also provides a water tank type cleaning device 1000, including a water tank 200 and the cleaning machine 100 described above; the water tank 200 is fixedly connected to the cleaning housing 10, and the expansion chamber 102 is at least partially located below the water tank 200 in the second direction Y.

[0102] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
