[0039] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0040] See Figures 1 to 14 , this embodiment provides a drying sink, including a sink body 10 and a drying device 20. The sink body 10 includes a sink bottom plate 11 and a sink side plate 12; the drying device 20 includes a drying housing 21 and a heating and air supply assembly 22. An isolated heating chamber 201 and a heat insulation chamber 202 are defined in the drying housing 21. The heating chamber 201 is located at the bottom of the sink bottom plate 11, and the heat insulation chamber 202 is located at the bottom of the heating chamber 201. The heating and air supply assembly 22 is used to form a flowing hot air flow in the heating chamber 201. The heat insulation chamber 202 has a ventilation opening 2022 communicating with the outside and an air outlet gap 2021. The heat in the heating chamber 201 is transferred to the heat insulation chamber 202 so that the air in the heat insulation chamber 202 flows out from the air outlet gap 2021 and blows towards the sink side plate 12, and the ventilation opening 2022 is used to supply air into the heat insulation chamber 202. Among them, Figure 4 , Figure 6 , Figure 10 , Figure 13 and Figure 14 show the air flow direction with arrows in

[0041] The heating chamber 201 is located at the bottom of the sink bottom plate 11, and the heating and air supply assembly 22 is used to form a flowing hot air flow in the heating chamber 201 to heat the sink bottom plate 11; the heat insulation chamber 202 is located at the bottom of the heating chamber 201, playing a role of heat insulation and heat preservation for the heating chamber 201 to reduce heat loss. The heat in the heating chamber 201 is transferred to the heat insulation chamber 202 to heat the air in the heat insulation chamber 202. The high-temperature air flow inside the heat insulation chamber 202 flows towards the air outlet gap 2021, and the air outlet gap 2021 blows towards the sink side plate 12, so that the sink side plate 12 is heated. Therefore, the sink bottom plate 11 and the sink side plate 12 are heated simultaneously, making full use of heat to improve the drying effect on the sink body 10. After drying, it remains dry and clean, creating a healthy kitchen.

[0042] Among them, the ventilation opening 2022 and the air outlet gap 2021 communicate with the outside, that is, communicate with the outside atmosphere outside the heat insulation cavity 202. Exemplarily, the air outlet gap 2021 is located at the top of the heat insulation cavity 202, which is more conducive to the upward flow of hot air out of the heat insulation cavity 202. The heat in the heating cavity 201 is transferred to the heat insulation cavity 202 to raise the temperature of the air in the heat insulation cavity 202. There is a temperature difference between the air inside the heat insulation cavity 202 and the outside air. The temperature difference causes gas flow. The hot air flows upward due to its low density and then flows out from the air outlet gap 2021. The outflow of the air flow in the heat insulation cavity 202 causes the pressure in the heat insulation cavity 202 to decrease, so that the outside air enters the heat insulation cavity 202 from the ventilation opening 2022 under the action of the pressure difference.

[0043] The ventilation opening 2022 is used to introduce air into the heat insulation cavity 202, and the installation position and quantity of the ventilation opening 2022 are not limited herein. Exemplarily, the drying water tank further includes a drainage assembly 40. The drainage assembly 40 penetrates through the heat insulation cavity 202, and the ventilation opening 2022 is arranged at the bottom of the heat insulation cavity 202 and arranged around the circumference of the drainage assembly 40. The installation position of the ventilation opening 2022 does not interfere with the installation of the drainage assembly 40, making full use of the space and simplifying the structure. The ventilation opening 2022 can be arranged in a circle around the circumference of the drainage assembly 40 to prevent interference with the drainage assembly 40. The drainage assembly 40 can adopt an existing drainage structure, which will not be elaborated herein. The heating cavity 201 and the drainage assembly 40 are hermetically connected to prevent air leakage from the heating cavity 201.

[0044] The water tank side plate 12 is arranged around the circumference of the water tank bottom plate 11 to enclose a cleaning cavity with the water tank bottom plate 11, and the air outlet gap 2021 extends around at least part of the circumference of the water tank side plate 12 on the outside of the cleaning cavity. The air outlet gap 2021 can be arranged in a circle around the water tank side plate 12 or arranged at intervals around the water tank side plate 12.

[0045] In this embodiment, the water tank body 10 is in a cuboid shape, the water tank bottom plate 11 is a rectangular plate, and the water tank side plates 12 are arranged around the circumferential edge of the water tank bottom plate 11. In other embodiments, the water tank body 10 can be cylindrical.

[0046] The drying housing 21 includes a first bottom plate 211 and a first side plate 212. The first side plate 212 is arranged around the circumference of the first bottom plate 211 to enclose a heating cavity 201 with the first bottom plate 211. In this embodiment, the first side plate 212 is connected to the water tank side plate 12, which can be specifically bolted or welded. In other embodiments, the first side plate 212 can also be connected to the water tank bottom plate 11.

[0047] The drying housing 21 further includes a second bottom plate 213 and a second side plate 214. The second side plate 214 is arranged around the circumference of the second bottom plate 213 to enclose a heat insulation cavity 202 with the second bottom plate 213. An air outlet gap 2021 is formed between the second side plate 214 and the water tank side plate 12. Specifically, the second side plate 214 is higher than the water tank bottom plate 11 by a set distance to ensure the heating area of the water tank side plate 12 and improve the heating efficiency.

[0048] Along the air outlet direction of the air outlet gap 2021, the flow area of the air outlet gap 2021 gradually decreases, enabling the air flow to fully contact the water tank side plate 12 and improving the heat exchange effect.

[0049] In this embodiment, the top edge of the second side plate 214 is bent towards the direction close to the water tank side plate 12, so that the flow area of the air outlet gap 2021 gradually decreases, and at the same time, it can also prevent foreign objects from falling into the air outlet gap 2021.

[0050] The second bottom plate 213 is connected to the first bottom plate 211 to fix the second bottom plate 213. Specifically, screw connection can be adopted, which is convenient for installation, disassembly and replacement. Optionally, the second side plate 214 is connected to the first side plate 212 to make the structure stable.

[0051] Exemplarily, a heat preservation member is arranged in the heat insulation cavity 202 to play a heat preservation role and reduce heat loss. The heat preservation member can be made of existing heat preservation materials. Exemplarily, a heat insulation air duct is arranged in the heat insulation cavity 202, and at least part of the heat insulation air duct extends in a zigzag manner between the ventilation opening 2022 and the air outlet gap 2021 to guide the air flow in the heat insulation cavity 202 to flow in a zigzag manner. By setting the heat insulation air duct, the air flow path is extended, the residence time of the air flow in the heat insulation cavity 202 is increased, and the heat preservation and heat exchange effect is improved. For example, a zigzag heat insulation air duct is formed by arranging a wind guide plate in the heat insulation cavity 202 to guide the air flow.

[0052] A water tank drying air duct 203 is arranged in the heating cavity 201. The water tank drying air duct 203 has an air flow inlet 2031, a first area 2032, a second area 2033 and an air flow outlet 2034 arranged in sequence. The first area 2032 is configured to guide the air flow entering from the air flow inlet 2031 to flow in a straight line. A diversion structure arranged between the first area 2032 and the second area 2033 guides the air flow in the first area 2032 to change direction and then enter the second area 2033. The drying air flow enters the water tank drying air duct 203 from the air flow inlet 2031, flows through the first area 2032 and the second area 2033 in sequence, and then flows out from the air flow outlet 2034. The first area 2032 guides the air flow entering from the air flow inlet 2031 to flow in a straight line. The resistance of the air flow is low, the flow rate is high and the eddy current is reduced, so that the air flow is evenly distributed, and thus uniform heating is achieved.

[0053] The projected area of the first region 2032 on the first bottom plate 211 is larger than the projected area of the second region 2033 on the first bottom plate 211. Ensuring that the first region 2032 is larger means that the large-area air flow remains in a straight line after entering from the air inlet 2031. The resistance of the air flow is lower, the flow rate is high, and the eddy current is reduced, so that the air flow is evenly distributed, and thus uniform heating of a large area is achieved.

[0054] Among them, the first region 2032 is the region where the air flow remains in a straight line after entering the water tank drying air duct 203 from the air inlet 2031. In some embodiments, the ratio of the projected area of the first region 2032 on the first bottom plate 211 to the projected area of the heating cavity 201 on the first bottom plate 211 is greater than or equal to 60%. In some embodiments, the ratio of the projected area of the first region 2032 on the first bottom plate 211 to the projected area of the heating cavity 201 on the first bottom plate 211 is greater than or equal to 70%. In some embodiments, the ratio of the projected area of the first region 2032 on the first bottom plate 211 to the projected area of the heating cavity 201 on the first bottom plate 211 is equal to 60%, 65%, 70%, 75% or 80%. The larger the first region 2032 is, the larger the area of the air flow remains in a straight line after entering from the air inlet 2031, ensuring uniform heating.

[0055] Along the flow direction of the air flow, the flow area of at least part of the first region 2032 gradually increases, slowing down the air flow speed, increasing the contact time between the air flow and the water tank bottom plate 11, making the air flow disperse and flow, and improving the heat exchange efficiency.

[0056] A flow guiding structure is provided between the first region 2032 and the second region 2033 to guide the air flow in the first region 2032 to change direction. The turning angle can be set according to actual needs. Exemplarily, the turning angle is less than or equal to 30 degrees to reduce the eddy current.

[0057] Optionally, the second region 2033 is configured to guide the air flow to remain in a straight line in the second region 2033, reducing the eddy current and making the temperature in the second region 2033 uniform, which is beneficial to uniformly heating the water tank bottom plate 11.

[0058] Along the flow direction of the air flow, the flow area of at least part of the second region 2033 gradually decreases, slowing down the air flow speed, increasing the contact time between the air flow and the water tank bottom plate 11, making the air flow disperse and flow, and improving the heat exchange efficiency.

[0059] The water tank drying air duct 203 may include one air path or multiple air paths. By providing multiple air paths, it further ensures that the bottom plate 11 of the water tank is uniformly heated. In this embodiment, a plurality of flow guiding rib plates 215 are provided in the heating cavity 201, and the plurality of flow guiding rib plates 215 divide the water tank drying air duct 203 into multiple air paths. By providing the flow guiding rib plates 215, it plays a guiding role for the air flow, making the air flow evenly distributed, and thus achieving uniform heating.

[0060] The flow guiding rib plates 215 may extend linearly or arc-shaped. At least some of the flow guiding rib plates 215 are bent and extended between the first region 2032 and the second region 2033 to form a flow guiding structure, guiding the air flow in the first region 2032 to flow to the second region 2033 after changing direction.

[0061] The flow guiding rib plates 215 and the first bottom plate 211 may be integrally formed or welded, which is convenient for processing and production. The heat insulation member is detachably connected to the flow guiding rib plates 215, which is convenient for replacing the heat insulation member.

[0062] The air flow inlet 2031 is used to supply air flow to multiple air paths. The air flow inlet 2031 includes a plurality of air flow inlets. It may be that one air flow inlet is provided corresponding to each air path, or it may be that at least two air paths share one air flow inlet. Specifically, the flow guiding rib plates 215 may divide the air flow inlet 2031 into a plurality of air flow inlets.

[0063] See Figures 3 to 10 , a heating air duct 204 is further provided in the heating cavity 201. The heating air duct 204 has a heating air inlet 2041 and a heating air outlet 2042. The heating air supply assembly 22 is arranged in the heating air duct 204. The heating air inlet 2041 is communicated with the outside, and the heating air outlet 2042 is selectively communicated with the air flow inlet 2031. The heating air supply assembly 22 can guide the outside air flow to enter from the heating air inlet 2041, flow through the heating air supply assembly 22 in the heating air duct 204, and then flow from the heating air outlet 2042 to the air flow inlet 2031 of the water tank drying air duct 203.

[0064] The heating air outlet 2042 is selectively communicated with the air flow inlet 2031. Optionally, the drying device 20 includes a reversing baffle 23 and a driving member 24. The reversing baffle 23 is rotatably connected to the drying housing 21, and the driving member 24 can drive the reversing baffle 23 to rotate between a first position and a second position so that the air flow inlet 2031 is communicated with or blocked from the heating air outlet 2042. Optionally, the drying device 20 includes a reversing valve. The reversing valve is arranged at the junction of the heating air outlet 2042 and the air flow inlet 2031, and by controlling the reversing valve to switch different flow paths to be opened or closed, the air flow inlet 2031 is communicated with or blocked from the heating air outlet 2042.

[0065] The heating and air supply assembly 22 includes a blower 221 and a heating element 222. The heating element 222 is disposed downstream of the blower 221, and the air flow outlet 2034 communicates with the heating air duct 204 and is located upstream of the blower 221. The air flow in the water tank drying air duct 203 flows out from the air flow outlet 2034 into the heating air duct 204, passes through the blower 221 and the heating element 222, and then flows out of the heating air duct 204 and re-enters the water tank drying air duct 203, realizing the air flow circulation in the water tank drying air duct 203 so that the heat can be fully utilized.

[0066] At least part of the heating air duct 204 extends in a zigzag manner so that dust deposits in the heating air duct 204, preventing dust from entering the downstream of the heating air duct 204. The heating air duct 204 includes an air inlet section 2043 and an air outlet section 2044. The air inlet section 2043 is located upstream of the blower 221, and the air outlet section 2044 is located downstream of the blower 221. At least one of the air inlet section 2043 and the air outlet section 2044 extends in a zigzag manner along the horizontal direction to facilitate dust deposition. In this embodiment, the air inlet section 2043 extends linearly along the horizontal direction, and the air outlet section 2044 extends in a zigzag manner along the horizontal direction. The blower 221 is arranged to intake air from above and discharge air from the side. Exemplarily, the air discharge direction of the blower 221 is opposite to the air flow direction of the air inlet section 2043, so a detour section is formed between the air inlet section 2043 and the air outlet section 2044, which is more conducive to dust deposition in the air inlet section 2043. In other embodiments, the air discharge direction of the blower 221 can be set at an angle to the air flow direction of the air inlet section 2043.

[0067] The heating and air supply assembly 22 further includes a baffle 223. The baffle 223 is disposed in the heating air duct 204. The air inlet section 2043 is located in the upper region of the baffle 223, and the air outlet section 2044 is located in the lower region of the baffle 223. The setting of the baffle 223 makes the air outlet section 2044 located below the air inlet section 2043. The heating air duct 204 can guide the air flow to flow along a U-shaped curve, and the dust entering the heating air duct 204 can deposit on the baffle 223, preventing dust from entering the blower 221 or the downstream of the blower 221.

[0068] At least part of the heating air inlet 2041 is lower than the baffle 223 so that the air flow enters the heating air duct 204 in a zigzag manner, and dust can deposit at the heating air inlet 2041. Less dust enters the upper region of the baffle 223. The air flow flows along the upper region of the baffle 223 to the upper side of the blower 221 for air intake, and the air flow flows out from the side of the blower 221 to the lower region of the baffle 223. Specifically, the heating air inlet 2041 of the heating channel is disposed on the first side plate 212, and the baffle 223 is spaced from the first side plate 212 so that the air flow at the heating air inlet 2041 can smoothly enter the heating air duct 204.

[0069] The drying device 20 further includes an air inlet passage 205. The heating air inlet 2041 communicates with the outside through the air inlet passage 205. At least part of the air inlet passage 205 allows air to flow in from top to bottom, so that dust deposits in the air inlet passage 205. Optionally, the bottom end of the air inlet passage 205 is lower than the heating air inlet 2041, so that dust deposits at the bottom end of the air inlet passage 205, preventing dust from entering the heating air inlet 2041.

[0070] Optionally, at least part of the air inlet passage 205 is bent and extended to deposit dust, preventing dust from entering the fan 221 or splashing in the heating air duct 204.

[0071] Specifically, the heating air inlet 2041 of the heating passage is the air outlet port of the air inlet passage 205. The heating air inlet 2041 is arranged on the first side plate 212. The outside air flows downward in the air inlet passage 205 to the heating air inlet 2041 of the heating air duct 204.

[0072] Exemplarily, the drying device 20 further includes a wind guiding structure 25. The wind guiding structure 25 is arranged outside the water tank body 10, and the air inlet passage 205 is arranged inside the wind guiding structure 25. The wind guiding structure 25 can be an integral structure or a split structure. In this embodiment, the wind guiding structure 25 includes a wind guiding housing 251 and a blowing housing 252. The blowing housing 252 is arranged at the top end of the wind guiding housing 251. The air inlet port 2051 of the air inlet passage 205 is arranged on the outer side of the upper part of the blowing housing 252, that is, on the side away from the water tank body 10. The outside air enters the air inlet passage 205 horizontally from the air inlet port 2051 and flows downward in the air inlet passage 205 to the heating air inlet 2041 of the heating air duct 204.

[0073] Among them, the blowing housing 252 extends along the length direction of the water tank body 10, and control components such as control buttons can be arranged on the blowing housing 252.

[0074] A guide rail 13 is arranged on the inner wall of the water tank body 10. The bowl basket assembly 30 can be lapped on the guide rail 13 and can slide along the guide rail 13. The bowl basket assembly 30 includes an upper box body 31 and a lower box body 32 that are buckled with each other and a water draining rack 33 arranged in the lower box body 32.

[0075] The bowl basket assembly 30 includes a bowl basket air inlet 301. The drying device 20 further includes a bowl basket drying air duct 206. One end of the bowl basket drying air duct 206 communicates with the heating air duct 204, and the other end of the bowl basket drying air duct 206 can supply drying air flow to the bowl basket air inlet 301. When it is necessary to dry the bowl basket assembly 30, the heating and blowing assembly 22 is started. The outside air flows through the air inlet passage 205, the heating air duct 204 and the bowl basket drying air duct 206 in sequence, and enters the bowl basket assembly 30 from the bowl basket air inlet 301 to dry the bowl basket assembly 30.

[0076] In this embodiment, both the air inlet channel 205 and the basket drying air duct 206 are located inside the air guiding structure 25, reducing the number of components and facilitating assembly. In other embodiments, two outer shells may be provided, with the air inlet channel 205 arranged in one outer shell and the basket drying air duct 206 arranged in the other outer shell.

[0077] At least part of the basket drying air duct 206 discharges air from bottom to top, causing the air flow to flow tortuously, facilitating dust deposition in the air duct to prevent the air flow from entering the basket assembly 30.

[0078] The basket drying air duct 206 has a basket air inlet 2061 and a basket air outlet 2062. The basket air inlet 2061 is selectively communicated with the heating air outlet 2042 of the heating air duct 204. A reversing baffle 23 is provided at the heating air outlet 2042 of the heating air duct 204. The reversing baffle 23 is rotatably connected to the drying housing 21, and a driving member 24 can drive the reversing baffle 23 to rotate between a first position and a second position so that the heating air outlet 2042 is communicated with the air flow inlet 2031 or the heating air outlet 2042 is communicated with the basket air inlet 2061.

[0079] See Figures 10 to 14 , when the reversing baffle 23 is in the first position, the heating air outlet 2042 is communicated with the air flow inlet 2031, and the heating air outlet 2042 is blocked from the basket air inlet 2061, that is, the air inlet channel 205, the heating air duct 204, and the sink drying air duct 203 are sequentially communicated, and the drying of the sink body 10 can be realized; when the reversing baffle 23 is in the second position, the heating air outlet 2042 is communicated with the basket air inlet 2061, and the heating air outlet 2042 is blocked from the air flow inlet 2031, that is, the air inlet channel 205, the heating air duct 204, and the basket drying air duct 206 are sequentially communicated, and the drying of the basket assembly 30 can be realized.

[0080] Exemplarily, the basket air inlet 2061 is arranged on the first side plate 212 of the drying housing 21, and the basket air outlet 2062 is arranged inside the sink body 10. During the sliding of the basket assembly 30 along the guide rail 13, the basket air inlet 2061 can be directly opposite to the basket air inlet 301 to supply drying air flow to the basket air inlet 301.

[0081] The drying device 20 further includes a water guiding structure 26. The water guiding structure 26 is disposed at the bottom of the drying housing 21. A water guiding channel 207 is formed inside the water guiding structure 26. The water guiding inlet 2071 of the water guiding channel 207 is communicated with the heating air duct 204. The water guiding inlet 2071 is located downstream of the heating element 222 and faces away from the heating element 222. The water guiding outlet 2072 of the water guiding channel 207 is communicated with the outside. The water in the heating air duct 204 can flow out from the water guiding structure 26 to prevent water from accumulating in the heating air duct 204. If water flows into the heating air duct 204 from the bowl basket drying air duct 206, it can flow out from the water guiding channel 207. The water guiding inlet 2071 is located downstream of the heating element 222 and faces away from the heating element 222 to prevent the air flow in the heating air duct 204 from flowing out through the water guiding channel 207.

[0082] A water guiding inclined surface is provided at a position in the heating air duct 204 close to the water guiding inlet 2071 to guide the water flow towards the water guiding inlet 2071 and prevent the water flow from entering the sink drying air duct 203.

[0083] One end of the water guiding structure 26 is located upstream of the heating element 222 and is hermetically connected to the heating air duct 204 to prevent the air flow in the heating air duct 204 from flowing out through the water guiding channel 207. Optionally, a double-layer sealing structure is adopted to improve the sealing effect.
