[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] See also Figures 1 to 14 This embodiment provides a drying water tank, including a water tank body 10 and a drying device 20. The water tank body 10 includes a water tank bottom plate 11 and a water tank side plate 12; the drying device 20 includes a drying shell 21 and a heating and air supply assembly 22. The drying shell 21 defines a heating chamber 201 and an insulating chamber 202 that are isolated from each other. The heating chamber 201 is located at the bottom of the water tank bottom plate 11, and the insulating 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 insulating chamber 202 has a vent 2022 and an air outlet gap 2021 that are connected to the outside world. The heat in the heating chamber 201 is transferred to the insulating chamber 202 so that the air in the insulating chamber 202 flows out from the air outlet gap 2021 and is discharged toward the water tank side plate 12. The vent 2022 is used to take air into the insulating chamber 202. Among them, Figure 4 、 Figure 6 、 Figure 10 、 Figure 13 and Figure 14 Arrows are used to show the direction of air flow.

[0041] The heating chamber 201 is located at the bottom of the sink bottom plate 11, and the heating air supply component 22 is used to form a flowing hot air flow in the heating chamber 201 to achieve heating of the sink bottom plate 11; the insulation chamber 202 is located at the bottom of the heating chamber 201, and plays a role in 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 insulation chamber 202 to heat the air in the insulation chamber 202, and the high-temperature air flow inside the insulation chamber 202 flows toward the air outlet gap 2021, and the air outlet gap 2021 discharges air toward the sink side plate 12, so that the sink side plate 12 is heated, thereby achieving simultaneous heating of the sink bottom plate 11 and the sink side plate 12, making full use of the heat to improve the drying effect of the sink body 10, keeping it dry and clean after drying, and creating a healthy kitchen.

[0042] The vents 2022 and the air outlet slits 2021 are in communication with the outside world, that is, with the atmosphere outside the insulation chamber 202. For example, the air outlet slits 2021 are located at the top of the insulation chamber 202, which facilitates the upward flow of hot air out of the insulation chamber 202. Heat within the heating chamber 201 is transferred to the insulation chamber 202, causing the air inside the insulation chamber 202 to heat up. The temperature difference between the air inside the insulation chamber 202 and the outside air causes gas flow. Due to the low density of the hot air, it flows upward and then flows out of the air outlet slits 2021. The outflow of air from the insulation chamber 202 causes the pressure inside the insulation chamber 202 to decrease, allowing the outside air to enter the insulation chamber 202 through the vents 2022 due to the pressure difference.

[0043] The vents 2022 are used to let air into the insulation chamber 202. The location and number of the vents 2022 are not limited here. For example, the drying water tank also includes a drainage component 40, which is passed through the insulation chamber 202. The vents 2022 are arranged at the bottom of the insulation chamber 202 and around the circumference of the drainage component 40. The location of the vents 2022 does not interfere with the installation of the drainage component 40, making full use of the space and simplifying the structure. The vents 2022 can be arranged in a circle around the circumference of the drainage component 40 to prevent interference with the drainage component 40. The drainage component 40 can adopt an existing drainage structure, which will not be repeated here. The heating chamber 201 and the drainage component 40 are sealed to prevent air leakage in the heating chamber 201.

[0044] The sink side panels 12 are arranged around the circumference of the sink bottom panel 11 to form a washing chamber with the sink bottom panel 11. The air outlet slots 2021 extend outside the washing chamber around at least a portion of the circumference of the sink side panels 12. The air outlet slots 2021 can be arranged around the sink side panels 12 in a circle or at intervals around the sink side panels 12.

[0045] In this embodiment, the sink body 10 is in the shape of a cuboid, the sink bottom plate 11 is a rectangular plate, and the sink side plates 12 are arranged around the circumferential edge of the sink bottom plate 11. In other embodiments, the sink body 10 may 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 disposed circumferentially around the first bottom plate 211 to enclose a heating chamber 201. In this embodiment, the first side plate 212 is connected to the water tank side plate 12, specifically by bolts or welding. In other embodiments, the first side plate 212 may also be connected to the water tank bottom plate 11.

[0047] The drying housing 21 also includes a second bottom plate 213 and a second side plate 214. The second side plate 214 is disposed circumferentially around the second bottom plate 213 to enclose a heat-insulating chamber 202. 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 positioned a predetermined distance above the water tank bottom plate 11 to ensure sufficient heating area for the water tank side plate 12 and improve heating efficiency.

[0048] Along the air outlet direction of the air outlet slot 2021, the flow area of ​​the air outlet slot 2021 gradually decreases, so that the air flow can fully contact the water tank side plate 12, thereby improving the heat exchange effect.

[0049] In this embodiment, the top edge of the second side panel 214 is bent toward the direction close to the sink side panel 12 so that the flow area of ​​the air outlet gap 2021 is gradually reduced, while also preventing foreign matter 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 to facilitate installation, removal and replacement. Optionally, the second side plate 214 is connected to the first side plate 212 to stabilize the structure.

[0051] Exemplarily, a thermal insulation component is provided in the thermal insulation cavity 202 to provide insulation and reduce heat loss. The thermal insulation component can be made of existing thermal insulation materials. Exemplarily, a thermal insulation air duct is provided in the thermal insulation cavity 202, and at least part of the thermal insulation air duct extends in a zigzag manner between the vent 2022 and the air outlet slit 2021 to guide the airflow in the thermal insulation cavity 202 to flow in a zigzag manner. By providing the thermal insulation air duct, the airflow path is extended, the residence time of the airflow in the thermal insulation cavity 202 is increased, and the thermal insulation and heat exchange effect is improved. For example, a zigzag thermal insulation air duct is formed by providing an air guide plate in the thermal insulation cavity 202 to guide the airflow.

[0052] The heating chamber 201 is provided with a water-trough drying duct 203, which comprises an air inlet 2031, a first region 2032, a second region 2033, and an air outlet 2034. The first region 2032 is configured to direct the airflow entering the air inlet 2031 to maintain a straight flow. A flow guide structure provided between the first and second regions 2032 and 2033 redirects the airflow in the first region 2032 before entering the second region 2033. Dry air enters the water-trough drying duct 203 through the air inlet 2031, flows through the first and second regions 2032 and 2033, and then exits through the air outlet 2034. The first region 2032 directs the airflow entering the air inlet 2031 to maintain a straight flow, resulting in low air resistance, high flow velocity, and reduced eddy currents. This ensures uniform air distribution and, consequently, even heating.

[0053] The projected area of ​​the first region 2032 on the first base plate 211 is larger than the projected area of ​​the second region 2033 on the first base plate 211. Ensuring that the first region 2032 is larger means that airflow over a large area maintains a straight flow after entering the airflow inlet 2031, resulting in lower airflow resistance, higher flow velocity, and reduced eddy currents, thus ensuring uniform airflow distribution and achieving uniform heating over a large area.

[0054] The first area 2032 is the area where the airflow maintains a straight flow after entering the water-drying air duct 203 from the airflow inlet 2031. In some embodiments, the ratio of the projected area of ​​the first area 2032 on the first bottom plate 211 to the projected area of ​​the heating chamber 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 area 2032 on the first bottom plate 211 to the projected area of ​​the heating chamber 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 area 2032 on the first bottom plate 211 to the projected area of ​​the heating chamber 201 on the first bottom plate 211 is equal to 60%, 65%, 70%, 75%, or 80%. The larger the first area 2032, the larger the area of ​​the airflow maintains a straight flow after entering from the airflow inlet 2031, ensuring uniform heating.

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

[0056] A guide structure is provided between the first area 2032 and the second area 2033 to guide the reversal of the airflow in the first area 2032. The reversing angle can be set according to actual needs. For example, the reversing angle is less than or equal to 30 degrees to reduce eddy currents.

[0057] Optionally, the second area 2033 is configured to guide the airflow to maintain a straight flow in the second area 2033, thereby reducing eddy currents and making the temperature in the second area 2033 uniform, which is conducive to uniform heating of the sink bottom plate 11.

[0058] Along the flow direction of the airflow, the flow area of ​​at least part of the second region 2033 gradually decreases, slowing down the airflow speed and increasing the contact time between the airflow and the water tank bottom plate 11, so that the airflow flows in a dispersed manner and the heat exchange efficiency is improved.

[0059] The water tank drying duct 203 can include a single air path or multiple air paths. The provision of multiple air paths further ensures uniform heating of the water tank bottom plate 11. In this embodiment, multiple guide ribs 215 are provided within the heating chamber 201. These guide ribs 215 divide the water tank drying duct 203 into multiple air paths. The provision of the guide ribs 215 guides the airflow, ensuring even distribution and thus achieving uniform heating.

[0060] The guide ribs 215 may extend in a straight line or in an arc shape. At least a portion of the guide ribs 215 bends and extends between the first area 2032 and the second area 2033 to form a guide structure, guiding the airflow in the first area 2032 to flow to the second area 2033 after reversing.

[0061] The guide ribs 215 and the first bottom plate 211 can be integrally formed or welded to facilitate processing and production. The heat insulating member and the guide ribs 215 are detachably connected to facilitate replacement of the heat insulating member.

[0062] The airflow inlet 2031 is used to supply airflow to multiple air paths. The airflow inlet 2031 includes multiple airflow inlets. One airflow inlet may be provided for each air path, or at least two air paths may share one airflow inlet. Specifically, the guide ribs 215 may separate the airflow inlet 2031 into multiple airflow inlets.

[0063] See also Figures 3 to 10 The heating chamber 201 is also provided with a heating air duct 204 having a heating air inlet 2041 and a heating air outlet 2042. A heating air supply assembly 22 is provided within the heating air duct 204. The heating air inlet 2041 is in communication with the outside world, and the heating air outlet 2042 is selectively in communication with the air inlet 2031. The heating air supply assembly 22 can guide the outside airflow to enter through 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 inlet 2031 of the water tank drying air duct 203.

[0064] The heating air outlet 2042 is selectively connected to the air 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. The driving member 24 can drive the reversing baffle 23 to rotate between a first position and a second position to connect or disconnect the air inlet 2031 from the heating air outlet 2042. Optionally, the drying device 20 includes a reversing valve, which is disposed at the junction of the heating air outlet 2042 and the air inlet 2031. The reversing valve is controlled to open or close different flow paths to connect or disconnect the air inlet 2031 from the heating air outlet 2042.

[0065] The heating and air supply assembly 22 includes a fan 221 and a heater 222. The heater 222 is located downstream of the fan 221. The air outlet 2034 is connected to the heating duct 204 and is located upstream of the fan 221. The air in the water-drying duct 203 flows out of the air outlet 2034 into the heating duct 204, passes through the fan 221 and the heater 222, flows out of the heating duct 204, and then reenters the water-drying duct 203, completing the air circulation within the water-drying duct 203 and ensuring that the heat is fully utilized.

[0066] At least a portion of the heating duct 204 extends in a zigzag pattern to allow dust to settle within the duct and prevent it from entering the downstream portion. The heating duct 204 includes an inlet section 2043 and an outlet section 2044. The inlet section 2043 is located upstream of the fan 221, while the outlet section 2044 is located downstream of the fan 221. At least one of the inlet section 2043 and the outlet section 2044 extends in a zigzag pattern horizontally to facilitate dust deposition. In this embodiment, the inlet section 2043 extends in a straight line horizontally, while the outlet section 2044 extends in a zigzag pattern horizontally. The fan 221 is configured for top air intake and side air discharge. For example, the outlet direction of the fan 221 is opposite to the airflow direction of the inlet section 2043, thereby forming a circuitous section between the inlet section 2043 and the outlet section 2044, further facilitating dust deposition in the inlet section 2043. In other embodiments, the air outlet direction of the fan 221 may be set at an angle to the air flow direction of the air inlet section 2043 .

[0067] The heating air supply assembly 22 also includes a baffle 223, which is disposed within the heating air duct 204. The air inlet section 2043 is located above the baffle 223, and the air outlet section 2044 is located below the baffle 223. The baffle 223 positions the air outlet section 2044 below the air inlet section 2043, allowing the heating air duct 204 to guide the airflow along a U-shaped curve. Dust entering the heating air duct 204 is deposited on the baffle 223, preventing the dust from entering the fan 221 or downstream of the fan 221.

[0068] At least a portion of the heating air inlet 2041 is lower than the shielding plate 223, so that the airflow enters the heating air duct 204 in a zigzag manner, allowing dust to settle at the heating air inlet 2041 and less dust to enter the area above the shielding plate 223. The airflow flows along the area above the shielding plate 223 to the upper air inlet of the fan 221, and then flows out from the side of the fan 221 to the area below the shielding plate 223. Specifically, the heating air inlet 2041 of the heating duct is provided on the first side panel 212, and the shielding plate 223 is spaced apart from the first side panel 212, so that the airflow from the heating air inlet 2041 can smoothly enter the heating air duct 204.

[0069] The drying device 20 further includes an air inlet duct 205, through which the heating air inlet 2041 communicates with the outside world. At least a portion of the air inlet duct 205 draws air from top to bottom, allowing dust to settle within the air inlet duct 205. Optionally, the bottom of the air inlet duct 205 is lower than the heating air inlet 2041, allowing dust to settle at the bottom of the air inlet duct 205 and prevent dust from entering the heating air inlet 2041.

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

[0071] Specifically, the heating air inlet 2041 of the heating channel is the air outlet port of the air inlet channel 205. The heating air inlet 2041 is arranged on the first side panel 212. The external air flow flows from top to bottom in the air inlet channel 205 to the heating air inlet 2041 of the heating air duct 204.

[0072] Exemplarily, the drying device 20 further includes an air guide structure 25, which is disposed on the outside of the water tank body 10, and an air inlet channel 205 is disposed inside the air guide structure 25. The air guide structure 25 can be an integrated structure or a split structure. In this embodiment, the air guide structure 25 includes an air guide housing 251 and an air supply housing 252, and the air supply housing 252 is disposed at the top of the air guide housing 251. The air inlet port 2051 of the air inlet channel 205 is disposed on the upper outer side of the air supply housing 252, that is, on the side away from the water tank body 10. The external airflow enters the air inlet channel 205 from the air inlet port 2051 in the horizontal direction, and flows downward along the air inlet channel 205 to the heating air inlet 2041 of the heating air duct 204.

[0073] The air supply housing 252 extends along the length direction of the water tank body 10 , and control components such as control buttons can be set on the air supply housing 252 .

[0074] The inner wall of the sink body 10 is provided with a guide rail 13, and the bowl basket assembly 30 can be overlapped with the guide rail 13 and can slide along the guide rail 13.

[0075] The basket assembly 30 includes a basket air inlet 301, and the drying device 20 also includes a basket drying air duct 206. One end of the basket drying air duct 206 is connected to the heating air duct 204, and the other end of the basket drying air duct 206 can provide drying air to the basket air inlet 301. When the basket assembly 30 needs to be dried, the heating air supply assembly 22 is activated, and external air flows through the air inlet duct 205, the heating air duct 204, and the basket drying air duct 206 in sequence, and enters the basket assembly 30 through the basket air inlet 301 to dry the basket assembly 30.

[0076] In this embodiment, the air inlet duct 205 and the basket drying duct 206 are both located within the air guide structure 25, reducing the number of parts and facilitating assembly. In other embodiments, two housings may be provided, with the air inlet duct 205 located in one housing and the basket drying duct 206 located in the other housing.

[0077] At least a portion of the basket drying air duct 206 discharges air from bottom to top, causing the air flow to flow in a zigzag manner, thereby facilitating dust deposition in the air duct and preventing the air flow from entering the basket assembly 30 .

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

[0079] See also Figures 10 to 14 When the reversing baffle 23 is in the first position, the heating air outlet 2042 is connected to the air inlet 2031, and the heating air outlet 2042 is separated from the bowl basket air inlet 2061, that is, the air inlet channel 205, the heating air duct 204 and the bowl basket drying air duct 203 are connected in sequence, which can achieve drying of the bowl basket body 10; when the reversing baffle 23 is in the second position, the heating air outlet 2042 is connected to the bowl basket air inlet 2061, and the heating air outlet 2042 is separated from the air inlet 2031, that is, the air inlet channel 205, the heating air duct 204 and the bowl basket drying air duct 206 are connected in sequence, which can achieve drying of the bowl basket assembly 30.

When the bowl basket assembly 30 slides along the guide rail 13, the bowl basket air inlet 2061 can be directly opposite the bowl basket air inlet 301 to supply drying air to the bowl basket air inlet 301.

[0081] The drying device 20 also includes a water guide structure 26 disposed at the bottom of the drying housing 21. A water channel 207 is formed within the water guide structure 26. A water inlet 2071 of the water channel 207 communicates with the heating duct 204. The water inlet 2071 is located downstream of the heating element 222 and faces away from the heating element 222. A water outlet 2072 of the water channel 207 communicates with the outside world. Water within the heating duct 204 can flow out of the water guide structure 26 to prevent water from accumulating within the heating duct 204. If water flows into the heating duct 204 within the bowl drying duct 206, it can flow out of the water channel 207. The water inlet 2071 is located downstream of the heating element 222 and faces away from the heating element 222 to prevent airflow within the heating duct 204 from flowing out of the water channel 207.

[0082] A water guiding slope is provided in the heating air duct 204 near the water guiding inlet 2071 to guide the water flow toward the water guiding inlet 2071 and prevent the water flow from entering the water tank drying air duct 203 .

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