Description

Technical Field

[0001] The present invention relates to the technical field of kitchen equipment, in particular to a drying sink. Background Art

[0002] Sinks and bowl baskets are essential kitchen items. The sink is used to wash food, dishes, and kitchenware, while the bowl basket is used to store them. To drain the dishes and utensils in the basket, you can place the bowl basket in the sink so that any water dripping from the dishes or utensils falls into the sink, facilitating drainage.

[0003] Because sinks are humid, naturally draining dishes is inefficient. Furthermore, the dampness of sinks keeps dishes in a constant, moist environment, making them susceptible to bacterial growth. Consequently, drying sinks have emerged in the industry, capable of drying dishes or kitchenware in a basket. The basket is placed in the drying sink, which has an air outlet that blows air toward the basket. The outlet is connected to a drying assembly, which provides hot air, which is then blown through the outlet toward the basket in the sink, drying the dishes and kitchenware in the basket.

[0004] However, when water is used in the sink, it is easy for water to enter the drying component through the air outlet, affecting the normal use of the drying component. Moreover, the water that enters the drying component is not easy to drain out. The long-term presence of water in the drying component can easily cause bacteria to grow in the drying component, thereby contaminating tableware, kitchen utensils, etc. through hot air. Moreover, the sink is in a humid environment and cannot be dried in time, which can easily lead to bacterial growth and mold, affecting the bowl basket in the sink, thereby causing secondary contamination of tableware and other items in the bowl basket.

[0054] like Figure 1 and Figure 2 As shown, this embodiment provides a drying sink, including a sink 100 and a bowl basket assembly 200. The bowl basket assembly 200 can be placed in the sink 100, and the bowl basket assembly 200 is used to place items such as tableware and kitchen utensils to facilitate draining.

[0055] In order to facilitate users to wash dishes, kitchen utensils or food, a faucet (not shown in the figure) is provided on the sink body 110, and the faucet is connected to the indoor water channel for user convenience.

[0056] In some embodiments, the bowl basket assembly 200 can be moved within the sink 100 and removed from the sink 100, so as to adjust the position of the bowl basket assembly 200 or remove and place the bowl basket assembly 200 according to the actual needs of the user, thereby better meeting the user's usage needs.

[0057] To prevent the drying sink from being in a humid state for a long time and thus breeding bacteria or mold, the drying sink also includes a drying assembly 300. The sink 100 includes a sink body 110 and an air outlet structure 120. The air outlet structure 120 is arranged on the sink body 110, and the bowl basket assembly 200 can be connected to the air outlet structure 120; the drying assembly 300 is used to provide a drying air flow. The drying assembly 300 includes a drying air duct, which can be selectively connected to the air outlet structure 120 so that the drying air flow is blown toward the bowl basket assembly 200, or the drying air duct blows air toward the bottom outer wall of the sink 100 to heat the temperature of the sink 100 and achieve the effect of drying the inner wall of the sink 100.

[0058] When the bowl basket assembly 200 is placed in the sink 100 and the tableware, kitchenware, and other items within the bowl basket assembly 200 need to be dried, the drying assembly 300 is activated, and the drying air duct is connected to the air outlet structure 120. The drying airflow provided by the drying assembly 300 can be blown into the bowl basket assembly 200 through the air outlet structure 120 to dry the tableware, kitchenware, and other items within the bowl basket assembly 200, thereby improving drying efficiency and preventing the tableware, kitchenware, and other items from being exposed to a humid environment for a long time and breeding bacteria. When the inner wall of the sink 100 needs to be dried, the drying assembly 300 is activated, and the drying air duct blows air toward the bottom outer wall of the sink 100. The drying airflow exchanges heat with the bottom outer wall of the sink 100, heating the sink 100 and achieving the purpose of drying the sink 100.

[0059] In this embodiment, the drying assembly 300 can dry both the bowl basket assembly 200 and the drying sink 100, which simplifies the structure of the drying sink, helps reduce costs, and improves product competitiveness.

[0060] like Figure 3 As shown, the drying assembly 300 further includes a heating element 320 and a fan 330 disposed in the drying air duct. The fan 330 is used to drive the air flow in the drying air duct, and the heating element 320 is used to heat the air flow to form hot air. The drying air duct is connected to the air outlet structure 120 so that the hot air can be blown toward the bowl basket assembly 200 through the air outlet structure 120 to dry the tableware, kitchen utensils, etc. in the bowl basket assembly 200.

[0061] Optionally, the heating element 320 may be an electric heating wire or other heating structure, as long as it can heat the airflow driven by the fan 330 to form hot air to dry tableware, kitchen utensils, etc.

[0062] When the user actually uses the faucet, the water outlet angle and water flow rate will vary according to actual needs, causing water to easily enter the drying component 300 through the air outlet structure 120, affecting the normal use of the drying component 300. Moreover, the water entering the drying component 300 cannot be discharged. The water exists in the drying component 300 for a long time, which can easily cause bacteria to grow in the drying component 300, thereby contaminating tableware, kitchen utensils, etc. through hot air.

[0063] To solve the above problem, in this embodiment, the air outlet structure 120 is provided with a waterproof part, which can prevent water from entering the drying air path through the air outlet structure 120 to ensure the normal operation of the drying component 300 and avoid the drying airflow provided by the drying component 300 from secondary contamination of tableware.

[0064] In some embodiments, such as Figure 4 and Figure 5 As shown, the waterproof portion includes an air outlet channel extending obliquely downward. The air outlet channel can realize oblique downward air outlet. On the one hand, it can prevent water from entering. Even if some water enters the air outlet structure 120, it can flow downward under the action of gravity to prevent water from entering the drying component 300; on the other hand, the drying air flow flows toward the bottom of the bowl basket assembly 200, returns after contacting the bottom surface of the bowl basket assembly 200, and flows upward under the action of its own characteristics, so as to fully contact the tableware, kitchen utensils and other items in the bowl basket assembly 200, thereby improving the drying uniformity and enhancing the user experience.

[0065] Optionally, the internal flow channels of the air outlet structure 120 may all extend downwardly, or as shown in FIG. Figure 5As shown, the air outlet structure 120 also includes a horizontal flow channel connected to the air outlet channel. The horizontal flow channel is located at one end of the air outlet channel close to the inside of the water tank body 110, and can also play a role in waterproofing and guiding the drying airflow.

[0066] In other embodiments, the waterproof portion includes an air deflector, and the air outlet structure 120 includes an air outlet. The air deflector is disposed in front of the air outlet to prevent water from entering the air outlet structure 120. Optionally, the air deflector extends obliquely from top to bottom toward the air outlet front. The provision of the air deflector can, on the one hand, shield the air outlet from the front of the air outlet to prevent water from entering the air outlet, and on the other hand, guide the air outlet, directing the airflow downward.

[0067] Optionally, the top of the air guide plate can be rotatably connected to the water tank body 110. When the air outlet structure 120 is not outputting air, the air guide plate blocks the air outlet to prevent water from entering the drying assembly 300 through the air outlet. When the air outlet is outputting air, the airflow acts on the air guide plate to push the air guide plate to rotate, thereby opening the air outlet and causing the airflow to be discharged obliquely downward under the guidance of the air guide plate.

[0068] In some other embodiments, the air outlet structure 120 includes a guide channel extending obliquely downward and a rotatably arranged air guide plate to improve the effect of preventing water from entering the drying component 300 and improve the guiding effect of the airflow to achieve oblique downward air outlet.

[0069] To improve the uniformity of air flow, in some embodiments, Figure 6 and Figure 7 As shown, the air outlet structure 120 includes a guide channel and a diverter plate 123 disposed in the guide channel. The diverter plate 123 can divert the airflow in the guide channel into at least two paths, which is conducive to uniform air outlet.

[0070] Optionally, the number of the diverter plates 123 can be set to at least two, and at least two diverter plates 123 are arranged at intervals to improve the effect of uniform air outlet.

[0071] In order to facilitate maintenance of the air outlet structure 120 , the air outlet structure 120 and the water tank body 110 are detachably connected, thereby making it easy to disassemble the air outlet structure 120 for replacement or cleaning.

[0072] In some embodiments, the air outlet structure 120 includes an air outlet member 121, which is disposed through the side wall of the sink body 110 and is detachably connected to the sink body 110. The air outlet member 121 is disposed through the sink body 110 to facilitate communication between the air outlet member 121 and the drying assembly 300 and the bowl basket assembly 200 located within the sink body 110, thereby simplifying the structure.

[0073] Optionally, the air outlet member 121 is snap-connected with the water tank body 110 to facilitate assembly and disassembly of the air outlet member 121 and reduce assembly difficulty.

[0074] In some embodiments, such as Figure 2 、 Figure 5 and Figure 6 As shown, a support portion 111 protrudes from the inner wall of the sink body 110. The support portion 111 is used to support the bowl basket assembly 200, and the air outlet member 121 is connected to the support portion 111. The provision of the support portion 111 not only supports the bowl basket assembly 200, simplifying the matching method of the bowl basket assembly 200 and the sink body 110, but also provides sufficient installation space for the air outlet member 121, ensuring that the air outlet member 121 has sufficient air outlet length, ensuring the length and inclination angle of the guide channel, and thus ensuring the waterproof effect of the air outlet structure 120 and the downward air outlet effect.

[0075] Specifically, support portions 111 are protruding from the inner walls on both sides of the opposite sides of the water tank body 110, and a support flange is provided at the opening of the box body 220. The support flange can be overlapped on the support portion 111 to suspend the box body 220 in the water tank body 110.

[0076] In some embodiments, such as Figure 6 As shown, the support portion 111 is in the shape of a horizontally extending strip, and the support flange of the box body 220 can overlap the support portion 111 and slide along the support portion 111 to adjust the position of the bowl basket assembly 200 in the sink body 110.

[0077] In some embodiments, combined Figure 5 As shown, the side wall of the water tank body 110 is bent toward the inside of the water tank body 110 to form a protruding support portion 111 on the inside of the water tank body 110, and a receiving groove is formed on the outside of the water tank body 110, and at least part of the air outlet member 121 is located in the receiving groove. The support portion 111 is formed by bending the side wall of the water tank body 110, which is convenient for processing and does not require additional connecting structures, resulting in a simple structure. The receiving groove is formed at the same time as the support portion 111. The receiving groove can provide sufficient installation space for the air outlet member 121, preventing the air outlet member 121 from protruding from the water tank body 110 as a whole and affecting the assembly of the entire machine, and is conducive to ensuring that the air outlet member 121 has a certain air outlet length, so as to improve the guiding effect of the air flow to be inclined downward.

[0078] To prevent water from remaining on the support portion 111 , in some embodiments, the top surface of the support portion 111 is tilted so that water dripping onto the support portion 111 can flow under gravity and avoid accumulating on the support portion 111 for a long time.

[0079] In some embodiments, the bottom surface of the support portion 111 is tilted so that water sliding down the support portion 111 to the bottom surface of the support portion 111 can flow toward the lower end under the action of gravity, and then gather and drip.

[0080] In some other embodiments, the top surface and the bottom surface of the support portion 111 may be inclined to improve the water diversion effect.

[0081] like Figure 7 As shown, in some embodiments, the air outlet member 121 includes an air outlet pipe 1211 and a snap-fit flange 1212 connected to the air outlet pipe 1211, a guide channel is formed in the air outlet pipe 1211, and the air outlet pipe 1211 is passed through the side wall of the sink body 110; the snap-fit flange 1212 is connected to one end of the air outlet pipe 1211 extending into the sink body 110, and the snap-fit flange 1212 abuts against the inner wall of the sink body 110 to prevent the air outlet pipe 1211 from being detached from the sink body 110.

[0082] Optionally, the air outlet pipe 1211 is interference-fitted with the water tank body 110 to achieve fixation, and no additional fixing structure is required, which makes installation easy.

[0083] In some embodiments, a seal 122 is provided between the snap-fit flange 1212 and the inner wall of the water tank body 110 to seal the gap between the snap-fit flange 1212 and the water tank body 110 to prevent air leakage through the gap and also to prevent water from flowing out through the gap.

[0084] Optionally, the sealing member 122 may be a sealing strip, which has a simple structure and good sealing effect.

[0085] In order to prevent some water from entering the drying air duct and being unable to be discharged, in this embodiment, Figure 8 As shown, a water leakage hole 3121 is provided on the bottom surface of the drying air duct, so that water entering the drying air duct through the air outlet structure 120 can be discharged through the water leakage hole 3121; wherein, the water leakage hole 3121 is located below the heating element 320, and at least the bottom end of the windward side of the heating element 320 is sealed with the drying air duct, thereby preventing the drying airflow passing through the heating element 320 from entering the bottom of the heating element 320, thereby preventing the drying airflow from being discharged through the water leakage hole 3121, thereby reducing heat and air volume losses.

[0086] In addition, the water leakage hole 3121 is set below the heating element 320. When the amount of water entering the drying air duct is small, the water marks remaining on the inner wall of the drying air duct are easier to dry, and part of the water flows to the heating element 320, and can be dried under the heat or residual temperature of the heating element 320, thereby reducing the actual amount of water discharged.

[0087] It should be noted that the windward side of the heating element 320 refers to the side of the heating element 320 that faces the air inlet direction of the drying air duct. By sealing the bottom surface of the windward side of the heating element 320 with the drying air duct, the airflow passing through the heating element 320 is directed inside or above the heating element 320. While fully exchanging heat with the heating element 320, the airflow is prevented from being discharged through the water leakage hole 3121, thereby reducing airflow and heat loss.

[0088] In this embodiment, first, the air outlet structure 120 that is inclined to discharge air downward is used to prevent water from entering the drying component 300 through the air outlet structure 120, thereby achieving the effect of preventing water ingress; through the provision of the water leakage hole 3121, even if some water enters the drying component 300, it can be drained through the water leakage hole 3121, thereby avoiding the long-term presence of water in the drying component 300 to breed bacteria, thereby preventing secondary contamination of tableware, etc.; through the bottom surface of the windward side of the heating element 320 and the sealing cooperation with the drying air path, the drying airflow can be prevented from entering the bottom of the heating element 320 and then being discharged through the water leakage hole 3121, thereby preventing heat and flow loss and ensuring drying efficiency.

[0089] In order to improve the drying effect, in some embodiments, Figure 2-Figure 4 As shown, the bowl basket assembly 200 includes a bowl basket box and a bowl basket 230 arranged in the bowl basket box. The bowl basket box includes a box body 220 and a box cover 210. The bowl basket 230 is used to accommodate items such as tableware and kitchen utensils. The bowl basket box is provided with a vent 221, which is connected to the air outlet structure 120 to allow dry air to enter the bowl basket box, which is conducive to gathering the dry air, thereby making full use of the heat of the dry air to dry items such as tableware and kitchen utensils.

[0090] In order to facilitate the drainage of water on tableware, kitchen utensils and other items, the bottom surface of the box body 220 is provided with a drain hole, and the water dripping from the tableware, kitchen utensils and other items can be drained through the drain hole to ensure that the bowl basket box is dry.

[0091] In some embodiments, such as Figure 9 As shown, the heating element 320 includes a heating body 321 and a heat exchange channel 322 disposed within the heating body 321. The heating body 321 divides the drying air path into a front section and a rear section, which are connected via the heat exchange channel 322. This arrangement, combined with the bottom surface of the windward side of the heating element 320 sealingly cooperating with the drying air path, ensures that all gas entering the front section enters the rear section through the heat exchange channel 322. This not only improves the heating effect on the airflow, but also prevents gas in the front section from entering the bottom of the heating element 320 and passing through the water leakage hole 3121, thereby reducing air volume loss.

[0092] In order to achieve a sealed fit between the bottom surface of the windward side of the heating element 320 and the drying air duct, in some embodiments, the bottom surface of the windward side of the heating element 320 is provided with a first mating surface, and the inner wall of the drying air duct includes a second mating surface. The first mating surface and the second mating surface are parallel and abut against each other to achieve surface-to-surface fit, so as to reduce the gap between the first mating surface and the second mating surface, avoid airflow passing through, and thereby achieve a sealing function.

[0093] Optionally, the first mating surface may be a plane or a curved surface, as long as the fitting effect between the first mating surface and the second mating surface can be ensured.

[0094] It can be understood that even if there is a tiny gap between the first mating surface and the second mating surface, since the heat exchange channel 322 connects the front air path and the rear air path, the resistance of the air flow through the heat exchange channel 322 is small, while the resistance through the gap between the first mating surface and the second mating surface is large, so that the air flow will flow into the heat exchange channel 322. Therefore, the sealing requirement of the bottom surface of the windward side of the heating element 320 and the drying air path can be achieved by adopting surface-to-surface matching.

[0095] In some other embodiments, a drainage seal is provided between the first mating surface and the second mating surface to further improve the sealing effect. Optionally, the drainage seal can be a sealing strip.

[0096] To guide airflow through heat exchange channel 322, the inner wall of the drying air duct further includes an air guide surface 31221 connected to the second mating surface. Air guide surface 31221 is located upstream of the second mating surface in the direction of airflow, and its height gradually increases along the direction of airflow. Airflow in the front section of the air duct, guided by air guide surface 31221, flows upward and enters heat exchange channel 322.

[0097] In addition, by setting the wind guide surface 31221, the position height of the heating element 320 can be raised. On the one hand, it prevents the heating element 320 from contacting the water below, and on the other hand, it can provide sufficient space for drainage by moving the heating element 320 upward.

[0098] To improve drainage, in some embodiments, the inner bottom surface of the drying air duct is concave to form a groove, and a drainage hole 3121 is provided at the bottom of the groove. This groove provides sufficient buffer space for drainage, preventing excessive water inflow and insufficient drainage capacity from contacting the heating element 320. The drainage hole 3121 is located in the low-lying groove, which facilitates the flow of water entering the drying air duct toward the drainage hole 3121.

[0099] Optionally, the groove can be formed by bending the inner wall of the drying air duct, so that a groove is formed on the inner side of the drying air duct and a protruding structure is formed on the outer side of the drying air duct. The processing technology is simple, the molding is convenient, and it is conducive to reducing costs.

[0100] To enhance the sealing effect between the windward side of the heating element 320 and the drying air duct, a partition 31223 is provided within the groove. The partition 31223 divides the groove into a water leakage groove 31225 and a sealing groove 31224. The sealing groove 31224 and the water leakage groove 31225 are aligned along the flow direction of the airflow within the drying air duct. Specifically, the sealing groove 31224 is located upstream of the water leakage groove 31225 along the flow direction of the airflow. The water leakage hole 3121 is provided on the bottom surface of the water leakage groove 31225. The top surface of the partition 31223 abuts against the heating element 320 to achieve a sealing effect. The abutment between the first and second mating surfaces, and the abutment between the partition 31223 and the heating element 320, achieves a double seal, preventing the drying airflow from being discharged through the water leakage hole 3121, thereby reducing heat and flow losses.

[0101] Optionally, the top surface of the partition 31223 is parallel to the bottom surface of the heating element 320 to achieve good surface-to-surface contact, thereby improving the sealing effect.

[0102] In some other embodiments, the partition 31223 and the heating element 320 may also be in line contact, as long as the sealing groove 31224 and the leakage groove 31225 can be separated into two non-connected grooves.

[0103] In some other embodiments, the sealing between the windward side of the heating element 320 and the drying air duct can be achieved only by the first mating surface and the second mating surface, or can be achieved only by the abutment between the partition 31223 and the heating element 320.

[0104] Since the heating element 320 is disposed above the groove, in order to ensure the stability of the heating element 320 , in some embodiments, a support member is disposed in the groove, and the support member is used to support the heating element 320 to improve the position stability of the heating element 320 .

[0105] Optionally, the support member can be arranged in at least one of the sealing groove 31224 and the leakage groove 31225, both of which can improve the supporting effect of the heating element 320.

[0106] like Figure 10 As shown, a lifting portion 31222 is provided on the inner wall of the drying air duct downstream of the water leakage hole 3121. The lifting portion 31222 is used to support the end of the heating element 320 opposite to the windward side to raise the height of the heating element 320 to prevent water entering the drying air duct from contacting the heating element 320 in the process of flowing toward the water leakage hole 3121.

[0107] In order to ensure that water can flow out through the leakage hole 3121, the lifting part 31222 includes at least two lifting blocks, and the two adjacent lifting blocks are arranged at intervals to form a water hole. The water entering the drying air path can flow into the groove through the water hole and be discharged through the leakage hole 3121.

[0108] In some embodiments, such as Figure 9 and Figure 11 As shown, the drying air duct includes a heating duct 3122 and a basket drying duct 3112. The heater 320 is disposed within the heating duct 3122, and the water leakage hole 3121 is in communication with the heating duct 3122. The basket drying duct 3112 is in communication with the air outlet structure 120, and the heating duct 3122 is located upstream of the basket drying duct 3112. The heating duct 3122 is located at the bottom of the water tank 100, utilizing the residual heat from the heating duct 3122 to dry the water tank 100. The basket drying duct 3112 extends from bottom to top and is located on one side of the water tank 100. This allows the hot air heated by the heating duct 3122 to flow upward after entering the basket drying duct 3112, thus reducing heat and air volume losses.

[0109] It can be understood that if water enters the drying air duct, the flow direction of the water is exactly opposite to that of the hot air. The water that enters the bowl basket drying air duct 3112 through the air outlet structure 120 will flow from top to bottom under the action of its own gravity, thereby entering the heating air duct 3122 at the bottom of the water tank 100 along the bowl basket drying air duct 3112, and flowing out through the leakage hole 3121, which is conducive to drainage.

[0110] In order to allow the water in the dish basket drying duct 3112 to enter the heating duct 3122 , in some embodiments, a guide structure is provided at one end of the dish basket drying duct 3112 connected to the heating duct 3122 , and the guide structure is used to guide the water to flow into the heating duct 3122 .

[0111] In some embodiments, the guide structure is a guide surface that is inclined from top to bottom toward the heating duct 3122 to guide water toward the heating duct 3122. Optionally, the guide surface can be a curved surface to reduce corners and avoid water residue at the corners; the guide surface can also be an inclined surface.

[0112] In some embodiments, the guide structure may be a guide rib, which extends toward the heating air duct 3122 to guide the flow direction of the water flow, thereby directing the water to the heating air duct 3122 .

[0113] In order to make the drying air duct able to heat the bottom outer wall of the water tank body 110, Figure 12 As shown, the drying air path also includes a tank drying air duct 3124, which is arranged at the bottom of the water tank body 110 and cooperates with the bottom heat exchange of the water tank body 110 to utilize the heat of the gas in the tank drying air duct 3124 to heat the water tank body 110, so that the water tank body 110 remains dry and prevents the water tank body 110 from becoming moldy or breeding bacteria due to moisture.

[0114] In order to improve the drying effect and facilitate the drying of the water tank body 110, the Figure 3 、 Figure 9 and Figure 11 As shown, the drying assembly 300 includes an air duct housing 310, which cooperates with the outer wall of the water tank body 110 to form a drying air duct. This arrangement reduces the size and material consumption of the air duct housing 310, thus lowering costs. Furthermore, the drying airflow within the drying air duct directly contacts the water tank body 110, facilitating heat transfer to the water tank body 110, thereby drying the water tank body 110, improving heat utilization, and avoiding heat waste.

[0115] The air duct housing 310 includes a side air duct housing 311 and a bottom air duct housing 312. The side air duct housing 311 is provided with an air inlet duct 3111 and a bowl drying duct 3112. The bottom air duct housing 312 is provided with a connecting air duct 3123, a heating air duct 3122, and a tank drying duct 3124. The air inlet duct 3111, the connecting air duct 3123, and the heating air duct 3122 are sequentially connected. The heating air duct 3122 can selectively connect to the bowl drying duct 3112 or the tank drying duct 3124. When the bowl drying basket assembly 200 is used, as shown in FIG. Figure 12 As shown, the heating air duct 3122 is connected to the bowl basket drying air duct 3112. The air flows from the air inlet duct 3111 and the connecting air duct 3123 into the heating air duct 3122. The air is heated by the heating element 320 of the heating air duct 3122 to form hot air. The hot air enters the bowl basket drying air duct 3112 and is then blown toward the bowl basket assembly 200 by the air outlet structure 120. When the water tank body 110 needs to be dried, as shown in FIG. Figure 13 As shown, the heating air duct 3122 is connected to the tank body drying air duct 3124, and the air flow enters the heating air duct 3122 from the air inlet duct 3111 and the connecting air duct 3123, and is heated by the heating element 320 of the heating air duct 3122 to form hot air, which enters the tank body drying air duct 3124 to heat the water tank body 110, thereby achieving the purpose of drying the water tank body 110.

[0116] It can be understood that the side duct shell 311 and the side wall of the sink body 110 form a bowl basket drying duct 3112. The heat of the drying airflow in the bowl basket drying duct 3112 is exchanged through direct contact with the sink body 110, which will heat the sink body 110 and can dry the sink body 110 to a certain extent.

[0117] Since the water tank body 110 is generally embedded in the cabinet, at least part of the drying air duct is set in the cabinet. On the one hand, the heat of the air flow in the drying air duct can have a certain drying effect on the cabinet and reduce the humidity in the cabinet; on the other hand, the cabinet can prevent heat from further dissipating, thereby reducing instantaneous heat and improving heat utilization.

[0118] In order to prevent the air flow in the tank drying duct 3124 from being discharged into the cabinet and affecting the stability of the air pressure inside the cabinet, in some embodiments, the end of the tank drying duct 3124 is connected to the heating duct 3122 to form a circulating flow channel. The air flow entering the tank drying duct 3124 flows back to the heating duct 3122 for heating and then enters the tank drying duct 3124 again, thereby improving the drying effect of the water tank body 110 through the circulating flow channel.

[0119] In order to achieve selective communication between the heating air duct 3122 and the bowl drying air duct 3112 or the trough drying air duct 3124, in some embodiments, the drying component 300 also includes a reversing paddle 340 and a reversing drive. The reversing paddle 340 is movably arranged in the drying air duct and can be switched between a first position and a second position; the output end of the reversing drive is connected to the reversing paddle 340, and the reversing drive can drive the reversing paddle 340 to move relative to the drying air duct to switch between the first position and the second position, thereby changing the flow direction of the drying airflow.

[0120] Specifically, when the reversing paddle 340 is in the first position, the heating air duct 3122 is connected to the tank drying air duct 3124, and the drying air flows into the tank drying air duct 3124 to dry the water tank body 110. When the reversing paddle 340 is in the second position, the heating air duct 3122 is connected to the bowl basket drying air duct 3112, and the drying air flows into the bowl basket assembly 200 through the bowl basket drying air duct 3112 and the air outlet structure 120 to dry the tableware or kitchen utensils in the bowl basket assembly 200.

[0121] In addition, when the reversing paddle 340 is in the second position, the reversing paddle 340 can also divert water entering the heating air duct 3122 through the bowl basket drying air duct 3112 to prevent water from entering the tank drying air duct 3124, thereby ensuring that all water can enter the heating air duct 3122 and be discharged through the water leakage hole 3121.

[0122] To facilitate the switching of the reversing paddle 340, the reversing paddle 340 is connected to the drying diversion rotation, and the reversing drive can drive the reversing paddle 340 to rotate relative to the drying air duct to switch between the first position and the second position, simplifying the structure and reducing costs.

[0123] Optionally, the reversing driving member may be a rotary motor, and an output end of the rotary motor is connected to one end of the reversing paddle 340 to drive the reversing paddle 340 to rotate.

[0124] In some embodiments, a second communication port 3114 is provided on the sidewall of the sink body 110, through which the heating air duct 3122 communicates with the dish drying basket assembly 200. A third communication port is provided on the heating air duct 3122 for communicating with the sink body drying air duct 3124. When the reversing paddle 340 is in the first position, the reversing paddle 340 blocks the second communication port 3114, preventing the heating air duct 3122 from communicating with the dish drying basket assembly 200. When the reversing paddle 340 is in the second position, the reversing paddle 340 blocks the third communication port, preventing the heating air duct 3122 from communicating with the sink body drying air duct 3124.

[0125] Since the end of the trough drying air duct 3124 is connected to the heating air duct 3122, the trough drying air duct 3124 includes a connected direct current zone and a recirculation zone. The direct current zone is connected to the outlet section of the heating air duct 3122, and the recirculation zone is connected to the inlet end of the heating air duct 3122. The flow directions of the airflow in the direct current zone and the recirculation zone are set at an angle to change the flow direction of the airflow so that the airflow flows back to the heating air duct 3122.

[0126] In order to improve the drying efficiency and heating uniformity of the water tank body 110, the width of the DC zone gradually increases along the flow direction of the airflow, so that the drying airflow can flow quickly in the DC zone and diffuse quickly, so as to achieve uniform and rapid temperature increase over a large area of the water tank body 110.

[0127] In some embodiments, the width of the recirculation zone gradually decreases along the flow direction of the airflow. It is understood that the temperature of the drying airflow in the direct flow zone is greater than that in the recirculation zone. To improve the uniformity of the temperature rise of the water tank body 110, the gradual contraction of the recirculation zone can gradually converge the drying airflow in the recirculation zone and slow down the airflow velocity, thereby improving the heat exchange between the airflow in the recirculation zone and the water tank body 110, thereby increasing the temperature of the water tank body 110 at the corresponding position of the recirculation zone, and thus achieving a uniform temperature rise of the water tank body 110.

[0128] In some embodiments, the air inlet duct 3111 extends from top to bottom, that is, the air flow in the air inlet duct 3111 flows from top to bottom, and the bottom end of the air inlet duct 3111 is connected to the connecting air duct 3123 through the first connecting port 3113.

[0129] In some embodiments, the air path within the bottom air duct shell 312 is curved and extended, so that dust and other impurities that enter the air inlet duct 3111 with the air flow enter the bottom air duct shell 312 under the action of gravity and air flow, and are then deposited within the bottom air duct shell 312 due to the circuitous flow of the air flow, thereby reducing the amount of dust and other impurities that enter the bowl basket drying duct 3112 and avoiding secondary contamination of the tableware or kitchen utensils within the bowl basket assembly 200.

[0130] Optionally, at least one of the connecting air duct 3123 and the heating air duct 3122 is curved, and / or the air flow direction at the connection position of the connecting air duct 3123 and the heating air duct 3122 is set at an angle, so that the air path located in the bottom air duct shell 312 is curved.

[0131] In some embodiments, the connecting air duct 3123 is located above the heating air duct 3122, and at least part of the first connecting port 3113 is directly opposite the heating air duct 3122, so that part of the airflow passing through the first connecting port 3113 will hit the outer wall of the heating air duct 3122, and change the flow direction, flowing upward into the connecting air duct 3123, which is conducive to the deposition of impurities such as dust.

[0132] In addition, the air flow in the connecting air duct 3123 needs to change its flow direction at the end and flow downward, thereby entering the heating air duct 3122. The air flow direction changes again, which is conducive to the deposition of impurities such as dust.

[0133] In some embodiments, the drying water tank further includes a control component 400 , which is disposed on the top of the water tank 100 and electrically connected to the drying component 300 to control the start and stop of the drying component 300 and operating parameters.

[0134] It should be noted that the control component 400 is a prior art in the art. This embodiment can adopt a control component 400 with any structure in the prior art, which will not be described in detail here.

[0135] Optionally, the air inlet of the drying air duct is provided on the control assembly 400 so that the airflow entering the drying air duct is clean air from outside the cabinet, thereby avoiding the inhalation of humid air inside the cabinet and causing secondary contamination to tableware or kitchen utensils. Specifically, the air inlet is connected to the air inlet duct 3111.

[0136] In some embodiments, when the bowl basket assembly 200 is disposed in the sink body 110, the bottom surface of the box body 220 is spaced apart from the inner bottom surface of the sink body 110 so that the box body 220 is suspended in the sink body 110. On the one hand, this facilitates the water in the box body 220 to drip from the drain hole and flow along the inner wall of the sink body 110, thereby being discharged from the drain port on the sink body 110. On the other hand, it facilitates the gas in the bowl basket box to flow out through the drain hole, which is beneficial to the air flow inside and outside the bowl basket box, thereby improving the drying efficiency and preventing bacteria from growing in the bowl basket box.

[0137] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
