[0036] Reference Figures 1 to 6 The present invention proposes a cleaning device 100, which is mainly a sink-type dishwasher. The sink-type dishwasher combines a sink and a dishwasher, which can not only improve the utilization rate of the kitchen, but also can conveniently clean fruits, vegetables or tableware.

[0037] In an embodiment of the present invention, the cleaning device 100 includes:

[0038] The washing tank body 10 is formed with a receiving cavity, and the side wall of the receiving cavity is provided with a first opening 111 and a second opening 131;

[0039] a cover plate 50, the cover plate 50 covers the opening of the accommodating cavity; and

[0040] The drying component 30 is connected to the first opening 111 and delivers gas into the accommodating cavity through the first opening 111, and the gas is blown out through the second opening 131;

[0041] The first opening 111 is closer to the opening of the accommodating cavity than the second opening 131 .

[0042] In the technical solution of the present invention, during the operation of the cleaning device 100, the cover plate 50 covers the opening of the accommodating chamber to prevent the liquid in the accommodating chamber from splashing out. After the cleaning procedure of the cleaning device 100 is completed, the drying component 30 sends the generated dry gas into the accommodating chamber from the first opening 111. The gas entering the accommodating chamber can dry the items in the accommodating chamber, and then the gas is discharged from the second opening 131 to the outside of the cleaning tank body 10. In the technical solution of the present invention, the first opening 111 is closer to the opening of the accommodating chamber than the second opening 131. The gas introduced from the first opening 111 is easier to reach the inner side wall of the cover plate 50, which is conducive to drying the inner side wall of the cover plate 50. In addition, the gas stays in the accommodating chamber for a long time during the process of flowing from the first opening 111 to the second opening 131, and can fully contact the items in the accommodating chamber, which is conducive to drying the items after cleaning.

[0043] See also Figure 4 The drying assembly 30 includes a housing 32, the housing 32 is provided with an air inlet 3211 and an air outlet 3221, and an air duct is formed between the air inlet 3211 and the air outlet 3221, a fan 33 is arranged in the air duct, and the air outlet 3221 is connected to the first opening 111. Driven by the fan 33, the outside air enters the air duct from the air inlet 3211, and enters the receiving chamber through the air outlet 3221 and the first opening 111, and dries the items in the receiving chamber and the inner wall of the receiving chamber.

[0044] Furthermore, a heating element 34 is also provided in the air duct of the drying component 30. Under the drive of the fan 33, the outside air enters the air duct from the air inlet 3211, and is heated by the heating element 34 to form hot air. The hot air further moves from the heating element 34 to the air outlet 3221, and enters the accommodating cavity through the first opening 111. The fan 33 is specifically arranged at the air inlet 3211, or between the air inlet 3211 and the heating element 34. In this embodiment, the heating element 34 is specifically a PTC (Positive Temperature Coefficient, thermistor) heating sheet.

[0045] It can be understood that the drying component 30 may include more or fewer structures. When no heating element is set in the air duct of the drying component 30, the fan 33 only introduces outside air into the receiving chamber, and dries the items to be dried in the receiving chamber and the inner wall of the receiving chamber through the flow of gas; in other embodiments of the technical solution of the present invention, refrigeration elements, drying elements, sterilization elements or other components for treating air can also be set in the air duct of the drying component 30, so that the gas entering the receiving chamber has a good drying effect, or has sterilization and disinfection effects.

[0046] In the embodiment of the present invention, the accommodating cavity has a front side wall 11 and a rear side wall 13 that are oppositely disposed. The first opening 111 is formed in the front side wall 11 , and the second opening 131 is formed in the rear side wall 13 .

[0047] The first opening 111 and the second opening 131 are respectively opened on two opposite side walls, so that the hot air generated by the drying assembly 30 can be evenly distributed in the accommodating cavity after entering the accommodating cavity through the first opening 111, thereby achieving a good drying effect on the items in the accommodating cavity.

[0048] The first opening 111 and the second opening 131 can be located at different positions of the front side wall 11 and the rear side wall 13, respectively, and can be arranged differently according to specific needs. In one embodiment, the first opening 111 is located at the middle position of the front side wall 11 in the horizontal direction; and / or, the second opening 131 is located at the middle position of the rear side wall 13 in the horizontal direction. The hot air entering the accommodating chamber is evenly distributed, and the inner wall of the cover plate 50 can be evenly dried. The first opening 111 and the second opening 131 are arranged neatly and beautifully in the cleaning tank body 10. It can be understood that in one embodiment, the first opening 111 and the second opening 131 are respectively arranged close to the left and right side walls of the accommodating chamber, so that the first opening 111 and the second opening 131 are respectively located at the diagonal positions of the cleaning tank body 30, so that the hot air entering the accommodating chamber from the first opening 111 has a larger flow range and a longer residence time in the accommodating chamber, and can more fully dry the items in the accommodating chamber and the inner wall of the accommodating chamber.

[0049] See also Figure 2 In the embodiment of the present invention, since the opening of the accommodating cavity on the sink-type dishwasher is generally opened upward, the first opening 111 is higher in the longitudinal direction than the second opening 131. The hot air entering the accommodating cavity from the first opening 111 expands due to heat, increases in volume, decreases in density, and becomes lighter in mass, and moves upward in the accommodating cavity. However, the second opening 131 is lower in the longitudinal direction than the first opening 111. The rising hot air accumulates on the inner wall surface of the cover body, dries the inner wall surface of the cover body, and then diffuses toward the surroundings and sinks to replenish the air originally lost due to heat, forming convection, and then wraps the items to be dried in the accommodating cavity, thereby achieving the purpose of drying both the cover body and the cleaned items well.

[0050] Of course, other arrangements are not excluded. When the cleaning device is a desktop dishwasher or a cabinet dishwasher, the cleaning device can be opened laterally, and the opening of the accommodating cavity is arranged laterally. The first opening 111 is closer to the cover plate 50 than the second opening 131, so that when the cleaning device is a desktop dishwasher or a cabinet dishwasher, the beneficial effect of good drying effect on the inner side of the cover plate 50 can also be achieved.

[0051] See also Figure 5 , a heating layer 51 is also provided inside the cover plate 50;

[0052] And / or, a super-hydrophobic material layer (not shown) is disposed on the inner side wall of the cover plate 50 .

[0053] In this embodiment, a heating layer 51 is provided inside the cover plate 50. The heating layer 51 is powered on to generate heat, and can heat the cover plate 50, thereby accelerating the evaporation of water on the inner wall of the cover plate 50, so that the drying effect of the inner wall of the cover plate 50 is better. Specifically, the cover plate 50 includes an inner mounting plate and an outer mounting plate that overlap each other, and the inner mounting plate is arranged toward the accommodating cavity. The heating layer 51 is located between the inner mounting plate and the outer mounting plate to prevent the water vapor in the accommodating cavity from damaging the heating layer 51. The heating layer 51 has a good water-proof effect. The heating layer 51 can be a heating structure such as a heating film, a heating tube or a heating wire. The circuit of the heating layer 51 is connected to the main control board of the cleaning device 100. The power of the heating layer 51 is 60W to 90W, and the working voltage is 220V.

[0054] Furthermore, a super-hydrophobic material layer can also be provided on the inner side wall of the cover plate 50. The surface stable contact angle of the super-hydrophobic material layer should be greater than 150°, and the rolling contact angle should be less than 10°, so that the liquid attached to the surface of the super-hydrophobic material layer will gather into strands and fall down, and the drying component 30 introduces hot air into the accommodating cavity, which can accelerate the falling and evaporation of the liquid on the surface of the super-hydrophobic material layer, so that the inner surface of the cover plate 50 has high drying efficiency. The super-hydrophobic material layer is further combined with the heating layer 51, so that the drying efficiency of the cover plate 50 is further improved and the drying effect is better. Specifically, the heating layer 51 is located between the inner mounting plate and the outer mounting plate, and the super-hydrophobic material layer is located on the side of the inner mounting plate away from the outer mounting plate.

[0055] See also Figure 2 The cleaning device 100 includes a cabinet (not shown) and a water tank body 20 , and both the cleaning tank body 10 and the water tank body 20 are embedded in the cabinet.

[0056] The sink body 20 is a common sink structure and can be used to wash any desired items. A faucet is provided at the edge of the sink body 20 , and the water outlet of the faucet faces the opening of the sink body 20 . The faucet can include a tap water faucet and a purified water faucet.

[0057] Furthermore, the cleaning tank body 10 and the water tank body 20 may be an integrated structure to simplify the production and processing process, and can simplify the process of installing the cleaning tank body 10 and the water tank body 20 on a cabinet.

[0058] The cover plate 50 of the cleaning device 100 is connected to the cleaning tank body 10 or to the cabinet, and the cover plate 50 includes a rotatably connected seat body and a cover body, the seat body is connected to the cleaning tank body 10, and the cover body covers the opening of the cleaning tank body 10 at the accommodating cavity, or rotates relative to the seat body to open the opening of the accommodating cavity. The seat body is specifically detachably connected to the cleaning tank body 10, and is preferably magnetically adsorbed to the cleaning tank body 10.

[0059] Combination Figure 2 and Figure 3The water tank body 20 is provided with a water tank overflow port 21, and the water tank overflow port 21 is connected to a drain pipe 40, and the water tank overflow port 21 and the second opening 131 are connected to the same drain pipe 40. In order to prevent the air discharged from the second opening 131 from affecting other objects, the second opening 131 is connected to the drain pipe 40, so that the hot air discharged from the second opening 131 can be discharged to the outside through the water tank overflow port 21 or the drain pipe 40, and the hot air discharged through the second opening 131 will produce condensed water when it encounters the air with a lower temperature outside. Connecting the second opening 131 to the drain pipe 40 can prevent the cleaning device 100 from leaking. Specifically, a connector is provided at the water tank overflow port 21, and the drain pipe 40 is connected to the water tank overflow port 21 through the connector. A connecting pipe 60 connects the second opening 131 and the connector, so that the hot air discharged from the second opening 131 is connected to the connector through the connecting pipe 60 and discharged from the water tank overflow port 21 or the drain pipe 40.

[0060] Under abnormal circumstances, the liquid in the accommodating chamber reaches a high water level, and the liquid flows into the air duct of the drying component 30 through the first opening 111. The heating element 34 located in the air duct is a strong electric device. In order to prevent the liquid in the air duct from flowing to the heating element 34 and causing damage to the heating element 34, the shell 32 is provided with a cleaning tank overflow port 323, and the cleaning tank overflow port 323 is located between the air outlet 3221 and the heating element 34.

[0061] The cleaning tank overflow port 323 is located at the lowest position between the air outlet 3221 and the heating element 34 , and the liquid between the air outlet 3221 and the heating element 34 can flow to the cleaning tank overflow port 323 under the guidance of the inner wall of the shell 32 and be discharged from the cleaning tank overflow port 323 .

[0062] In the embodiment of the present invention, the drying component 30 is tilted on the cleaning tank body 10 , specifically, the location of the cleaning tank overflow port 323 is tilted further downward than the location of the heating element 34 , so as to accelerate the liquid in the air duct to flow out through the cleaning tank overflow port 323 .

[0063] See also Figure 5 The shell 32 is provided with a wind shield 35 in the air duct. The wind shield 35 extends from the heating element 34 to the air outlet 3221 and is located above the overflow port 323 of the cleaning tank.

[0064] The hot air generated by the drying component 30 flows from the heating element 34 to the air outlet 3221. The wind shield 35 guides the flow of the hot air. In this embodiment, the wind shield 35 is arranged close to the overflow port 323 of the cleaning tank to shield the overflow port 323 of the cleaning tank, thereby reducing the leakage of hot air at the overflow port 323 of the cleaning tank.

[0065] Furthermore, one end of the wind shielding rib 35 close to the heating element 34 is bent toward the side where the overflow port 323 of the cleaning tank is located.

[0066] In the process of hot air heated by the heating element 34 moving toward the air outlet 3221, it encounters the bend at the end of the wind shield rib 35 and flows along the upper part of the wind shield rib 35 under the guidance of the bend. Only a small part of the hot air will pass over the bend and flow along the lower part of the wind shield rib 35. A small part of the hot air located at the lower part of the wind shield rib 35 will leak from the overflow port 323 of the cleaning tank. Therefore, the bend setting greatly reduces the loss of hot air and improves the drying efficiency of the drying component 30.

[0067] Furthermore, the end of the wind shield 35 is bent toward the overflow port 323 of the cleaning tank, so that after the liquid entering the air duct from the air inlet 3211 flows along the inner wall of the shell 32 to the wind shield 35, it can flow directly to the overflow port 323 of the cleaning tank under the guidance of the bent part and be discharged.

[0068] The housing 32 has a water retaining platform 36 , which extends from the air outlet 3221 toward the inside of the air duct, and gradually increases in height from the air outlet 3221 to the inside of the air duct.

[0069] The liquid entering the air duct from the air outlet 3221 can flow back into the accommodating cavity under the guidance of the water retaining sink 36 .

[0070] Continue to see Figure 5 The shell 32 is provided with a water retaining rib 37 in the air duct, and the water retaining rib 37 is connected to the edge of the shell 32 at the air outlet 3221. The water retaining rib 37 can block the liquid entering the air duct from the air outlet 3221. The water retaining rib 37 extends along the extension direction of the shell 32, so as to guide the hot air in the air duct.

[0071] The shell 32 includes an air inlet portion 321 and an air outlet portion 322. An air inlet 3211 is provided at one end of the air inlet portion 321, and the other end is connected to the air outlet portion 322. An air outlet 3221 is provided at the end of the air outlet portion 322 away from the air inlet portion 321. The fan 33 and the heating element 34 are both located in the air inlet portion 321. The overflow port 323 of the cleaning tank is opened in the air outlet portion 322 and is located at the lower side of the air outlet portion 322 adjacent to the air inlet portion 321.

[0072] The air outlet portion 322 comprises a first connecting section 3222 and a second connecting section 3223. One end of the first connecting section 3222 is connected to the air inlet portion 321, and the other end extends upward. One end of the second connecting section 3223 is connected to the upper end of the first connecting section 3222, and the other end extends toward the side of the first connecting section 3222, and is provided with an air outlet 3221. The first connecting section 3222 and the second connecting section 3223 are connected by an arc transition connection. The second connecting section 3223 and the air inlet portion 321 are located on the same side of the first connecting section 3222.

[0073] The outside air enters the air duct from the air inlet 3211 and flows along the air inlet portion 321 to the heating element 34, and is heated by the heating element 34 to form hot and dry air with a relatively high temperature. Since the density of hot air is relatively low, in order to reduce the energy loss of hot air during the flow process, the first connecting section 3222 is extended upward, and the hot air flows upward under the guidance of the first connecting section 3222. Since the installation space on the cleaning tank body 10 is limited and the first opening 111 is located in the middle position of the front side wall 11 in the horizontal direction, the second connecting section 3223 extends laterally toward the first connecting section 3222 so that the air outlet 3221 is connected to the first opening 111.

[0074] Furthermore, the second connecting section 3223 is gradually lowered from the end of the first connecting section 3222 to the direction of the air outlet 3221, so as to reversely guide the liquid entering the air duct from the air outlet 3221 into the accommodating cavity, thereby preventing the liquid from further flowing to the first connecting section 3222 and further flowing to the heating element 34 to damage the heating element 34.

[0075] The shell 32 is also provided with a first connecting plate 3224, which connects the second connecting section 3223 and the air inlet 321, thereby increasing the connection strength of the shell 32. Specifically, the second connecting section 3223 and the first connecting plate 3224 are an integral structure. Furthermore, the first connecting section 3222, the second connecting section 3223 and the first connecting plate 3224 are an integral structure, and the first connecting plate 3224 is connected to the air inlet 321 by other common connecting structures such as screws or bolts.

[0076] See also Figure 1In one embodiment, the drying component 30 further includes an outer cover shell 31. In this embodiment, the fan 33 of the drying component 30 is located at the air inlet 3211. The outer cover shell 31 is connected to the housing 32 and at least covers the air inlet 3211. The housing 32 is provided with a through hole facing the air inlet 3211, so that the outside air can enter the air inlet 3211 through the through hole. Furthermore, the outer cover shell 31 extends to cover the outside of the heating element, which can not only prevent people from touching the heating element 34 and prevent the strong electric heating element 34 from causing harm to the human body, but also the outer cover shell 31 can block the heat of the heating element 34 to a certain extent, reduce the temperature of the heating element 34 transferred to the cabinet, and prevent damage to the part that does not need to be heated; the outer cover shell 31 also has the effect of facilitating wiring, and can isolate and protect the wiring of the drying component 30.

[0077] A connection frame 3225 is extended from the outer side of the air outlet 3221 of the shell 32 to connect to the cleaning tank body 10 . A second connection plate 3226 is also extended from the connection frame 3225 to connect to the outer cover shell 31 .

[0078] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
