Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a dual-purpose washing machine which can be switched between an ordinary water tank and a fruit and vegetable washing machine. Background Art

[0002] Currently, most users have two sinks in their kitchens. If a sink-type dishwasher is installed, one sink is used as a normal sink, and the other sink is used as a washing sink for the dishwasher. The washing sink is equipped with a spray system and cannot be used as a normal sink.

[0003] The applicant's prior application CN202211599697.X "A dual-purpose cleaning machine" discloses a structure, which includes a water tank body, a water pumping mechanism, and a vegetable basket. The top of the return water area is covered with a filter plate, and the filter plate is provided with an installation opening for the top wall of the water pumping mechanism to be exposed. The water outlet is provided on the top wall of the water pumping mechanism and exposed at the installation opening; a water inlet that can be detachably connected to the water outlet of the water pumping structure is provided at the bottom of the vegetable basket, and a number of water spray holes are provided on the inner wall of the vegetable basket.

[0004] The above-mentioned vegetable basket has its own flow channel and a number of water spray holes are set on the inner wall of the basket. The water column can be sprayed directly onto the fruits and vegetables in the basket through the built-in flow channel of the vegetable basket. Without the obstruction of the bottom wall of the vegetable basket, the water column can cover the interior of the vegetable basket over a large area and with high pressure, eliminating cleaning dead corners and improving the cleaning effect. The vegetable basket can be directly placed in the sink body and connected to the water pump mechanism to achieve water return, and can be used as a fruit and vegetable washing machine. After the vegetable basket is taken out, it automatically switches to an ordinary sink for use, which is easy to operate and use. However, since the slag collection basket and the water pump are arranged side by side at the bottom of the sink, in order to center the water pump at the bottom of the sink, the slag collection basket can only be offset at the bottom of the sink, resulting in poor return water and slag collection effect. Moreover, since the return water area needs to surround both the slag collection basket and the water pump, there are many concave and convex structures on the bottom wall of the return water area. After washing, residual water is formed at the bottom of the return water area. Over time, bacteria breed and the residual water becomes smelly, which greatly affects the fruit and vegetable cleaning experience. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a dual-purpose cleaning machine that improves the return water and slag collection effects and avoids residual water by integrating the return water and drainage structures and arranging them in the center of the bottom of the water tank in response to the current status of the existing technology.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A dual-purpose cleaning machine comprising:

[0008] The bottom of the water tank body is provided with a concave water return area;

[0009] A water pump mechanism is provided in the water return area and is provided with a water intake port connected to the water return area and a water outlet for water supply output;

[0010] A vegetable basket, wherein the vegetable basket is provided with an internal hollow flow channel, the bottom of the vegetable basket is provided with a water inlet that can be detachably connected to the water outlet of the water pump mechanism, and the inner wall of the vegetable basket is provided with a plurality of water spray holes;

[0011] a sealing cover movably provided at the water outlet of the water pumping mechanism, for opening the water outlet when the vegetable basket is connected to the water pumping mechanism, and for closing the water outlet when the vegetable basket is disconnected from the water pumping mechanism;

[0012] It is characterized in that the top of the return water area is covered with an annular filter plate, the central part of the filter plate forms a mounting opening for exposing the top wall of the water supply pump mechanism, the water outlet is opened on the top wall of the water supply pump mechanism and arranged corresponding to the central part of the mounting opening, and the bottom of the return water area is provided with a drain outlet and a drain assembly.

[0013] Preferably, the filter plate includes an edge region, a filtration region, and a mounting region, arranged radially inward from the outside. The edge region is connected to the top edge of the return water region. The filtration region is sunken relative to the edge region and the mounting region and is provided with filter mesh holes. The mounting region is provided with the mounting opening. With this structure, the filter plate simultaneously performs return water filtration and debris collection, greatly simplifying the overall structure and facilitating removal of the filter plate for debris cleaning.

[0014] Preferably, the bottom wall of the water tank body is partially recessed at the top edge of the return water area to form a mounting groove arranged around the top edge of the return water area, and the edge area of ​​the filter plate is placed in the mounting groove. This structure helps to improve the installation reliability of the filter plate and facilitates assembly and disassembly.

[0015] Preferably, the cross-section of the mounting area is an inverted U-shaped structure, with the mounting opening formed on the closed surface of the U-shaped structure. The top of the water pumping mechanism is inserted into the mounting opening, and when assembled, the tops of the two components form a guide surface that is taller than the top opening of the return water area, with the guide surface gradually sloping downward radially from the center toward the edge. This structure facilitates compact installation between the filter plate and the water pumping mechanism, while also effectively ensuring that no excess water remains at the top of the water pumping mechanism, due to the elevated guide surface relative to the top opening of the return water area.

[0016] Preferably, the width of the filter area in the radial direction of the filter plate gradually decreases from top to bottom, forming a V-shaped structure. The filter mesh is provided at the bottom of the V-shaped structure. The top of the first inclined wall of the V-shaped structure smoothly connects to the edge area, and the top of the second inclined wall of the V-shaped structure smoothly connects to the bottom of the mounting area. This structure can improve the slag collection efficiency and water return efficiency of the filter area.

[0017] Preferably, the return water area is formed into a cylindrical structure, and the pumping mechanism is formed into a disc-shaped structure. The pumping mechanism is centrally located within the return water area, and the drain outlet is located at the bottom and / or sidewall of the return water area. Placing the pumping mechanism concentrically with the return water area effectively saves assembly space and simultaneously enables the pumping mechanism and slag collection area to be centrally located at the bottom of the water tank body, thereby improving slag collection while maintaining good return water performance.

[0018] Preferably, the inner bottom wall of the return water area protrudes upward in the center to form a guide platform, the bottom of the water pump mechanism is supported on this guide platform, and the drain outlet is provided at the junction of the bottom wall and the side wall of the return water area. The inner bottom wall of the return water area gradually slopes downward from the side opposite the drain outlet toward the drain outlet to form a water guide surface, which is arranged around the periphery of the guide platform. This structure is conducive to achieving a zero-residual-water bottom at the bottom of the return water area.

[0019] Preferably, the bottom wall of the return water area forms a guide surface at the corresponding drain outlet that gradually slopes downward along the direction of water flow. The drain outlet is connected to the outer side of the drain assembly. The drain assembly may include a drain valve and a drain pump. This structure facilitates rapid drainage of water, ensuring that no residual water remains at the bottom of the return water area.

[0020] Preferably, a driving member for providing power to the water pumping mechanism is provided at the outer bottom of the water tank body, and the output shaft of the driving member passes upward through the guide platform at the bottom of the water tank body and is connected to the water pumping mechanism.

[0021] Compared with the existing technology, the advantages of the present invention are: the present invention arranges the filter plate into an annular structure that can surround the water pumping mechanism, and the filter plate takes into account the functions of filtering return water and collecting slag. The integrated arrangement structure of the water pumping mechanism and the filter plate realizes that the two are centered relative to the bottom of the water tank body at the same time, which greatly simplifies the bottom installation structure of the return water area, is conducive to improving the return water and slag collection effects, and avoids residual water.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 6 As shown, the dual-purpose cleaning machine of this embodiment includes a water tank body 1, a water pump mechanism 2, a vegetable basket 3, and a cover 4. The bottom of the water tank body 1 is provided with a concave water return area 11, the top of which is covered with a filter plate 6. The water pump mechanism 2 is located in the water return area 11 and has a water intake 201 connected to the water return area 11 and a water outlet 202 for water supply and output. The vegetable basket 3 is located above the water return area 11 and can be placed in or removed from the water tank body 1. The vegetable basket 3 is used to hold fruits and vegetables.

[0030] The basket 3 is provided with an internal hollow flow channel. The bottom of the basket 3 is provided with a water inlet 31 that can be detachably connected to the water outlet 202 of the water pumping mechanism 2. The inner wall of the basket 3 is provided with a plurality of water spray holes 32. A cover 4 is movably provided at the water outlet 202 of the water pumping mechanism 2, and is used to open the water outlet 202 when the basket 3 is connected to the water pumping mechanism 2 and to close the water outlet 202 when the basket 3 is disconnected from the water pumping mechanism 2. The water pumping mechanism 2, the basket 3, and the cover 4 can adopt the structure described in the applicant's prior application CN202211599697.X, and will not be described in detail here.

[0031] The return water area 11 of this embodiment is formed into a barrel-shaped structure, and the water pumping mechanism 2 is formed into a disc-shaped structure. The water pumping mechanism 2 is centrally arranged in the return water area 11. The filter plate 6 of this embodiment is annular, and the central portion of the filter plate 6 forms an installation opening 60 for the top wall of the water pumping mechanism 2 to be exposed. The water outlet 202 is provided on the top wall of the water pumping mechanism 2 and is arranged corresponding to the central portion of the installation opening 60. The bottom of the return water area 11 is provided with a drain port 111 and a drain assembly 112. Arranging the water pumping mechanism 2 concentrically with the return water area 11 can effectively save assembly space and simultaneously realize the central arrangement of the water pumping mechanism 2 and the slag collection area at the bottom of the water tank body 1, which is beneficial for improving the slag collection effect while maintaining a good return water effect.

[0032] The filter plate 6 of this embodiment includes an edge region 61, a filtration region 62, and a mounting region 63, arranged radially inward. The edge region 61 is connected to the top edge of the return water area 11. The filtration region 62 is lowered relative to the edge region 61 and the mounting region 63 and defines a filter mesh 621. The mounting region 63 defines a mounting opening 60. This structure allows the filter plate 6 to simultaneously perform return water filtration and debris collection, greatly simplifying the overall structure and facilitating removal of the filter plate 6 for debris cleaning.

[0033] Specifically, the bottom wall of the water tank body 1 is partially recessed at the top edge of the return water area 11, forming a mounting groove 12 arranged around the top edge of the return water area 11. The edge area 61 of the filter plate 6 rests within this mounting groove 12. This structure improves the reliability of the filter plate installation and facilitates assembly and disassembly. The mounting area 61 has an inverted U-shaped cross-section, with the mounting opening 60 formed on the closed surface of this U-shaped structure. The top of the pumping mechanism 2 is inserted into the mounting opening 60. When assembled, the tops of the two components form a guide surface 01 that is higher than the top opening of the return water area 11 and gradually slopes downward radially from the center toward the edges. This structure not only facilitates compact installation between the filter plate 6 and the pumping mechanism 2, but also effectively ensures that no excess water remains at the top of the pumping mechanism 2, as the guide surface 01 is elevated relative to the top opening of the return water area 11.

[0034] The width of the filter area 62 in the radial direction of the filter plate 6 gradually decreases from top to bottom, forming a V-shaped structure. The filter mesh 621 is located at the bottom of the V-shaped structure. The top of the first inclined wall of the V-shaped structure smoothly connects to the edge area 61, and the top of the second inclined wall of the V-shaped structure smoothly connects to the bottom of the mounting area 63. This structure can improve the slag collection efficiency and water return efficiency of the filter area 62.

[0035] The inner bottom wall of the return water area 11 protrudes upward in the center to form a guide platform 13. The bottom of the water pumping mechanism 2 is supported on this guide platform 13. The drain outlet 111 is located at the junction of the bottom wall and the side wall of the return water area 11. The inner bottom wall of the return water area 11 gradually slopes downward from the side opposite the drain outlet 111 toward the drain outlet 111 to form a water guide surface 02. This water guide surface 02 is arranged around the periphery of the guide platform 13. This structure helps to ensure that there is no residual water at the bottom of the return water area 11.

[0036] The bottom wall of the return water area 11 forms a guide surface 03 that gradually slopes downward along the direction of water flow, corresponding to the drain outlet 111. A drain assembly 112 is connected to the outside of the drain outlet 111. The drain assembly 112 may include a drain valve and a drain pump. This structure facilitates rapid drainage, ensuring that no residual water remains at the bottom of the return water area 11.

[0037] A driving member 7 for providing power to the water pumping mechanism 2 is provided at the outer bottom of the water tank body 1 , and an output shaft 71 of the driving member 7 passes upward through the guide platform 13 at the bottom of the water tank body 1 and is connected to the water pumping mechanism 2 .

[0038] In this embodiment, the filter plate 6 is configured as an annular structure that can surround the water pumping mechanism 2. The filter plate 6 takes into account the functions of filtering backwater and collecting slag. The integrated arrangement structure of the water pumping mechanism 2 and the filter plate 6 can simultaneously center the two relative to the bottom of the water tank body 1, greatly simplifying the bottom installation structure of the return water area 11, which is beneficial to improving the return water and slag collection effects and avoiding residual water.
