Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and more particularly to a drying sink. Background Technology

[0002] Sinks and dish racks are essential kitchen items. Sinks are used for washing ingredients, tableware, and cookware, while dish racks are used for storing tableware and cookware. To allow the tableware and cookware in the dish rack to drain, the dish rack can be placed in the sink so that any water droplets can fall into the sink for easy drainage.

[0003] Because sinks are in a humid environment, naturally draining dishes is inefficient, and the dampness keeps the dishes constantly moist, making them prone to bacterial growth. To address this, a drying sink has emerged. A dish rack is placed inside the drying sink, which has air vents that blow air towards the rack. These vents are connected to a drying assembly, which provides hot air that is blown through the vents into the rack to dry the dishes and utensils. However, due to the upward flow of hot air, existing drying sinks cause insufficient contact between the hot air and the bottom of the rack, resulting in uneven drying. Furthermore, when water is used in the sink, it can easily enter the drying assembly through the vents, affecting its operation and making drainage difficult. The lingering water inside the drying assembly can also lead to bacterial growth, causing secondary contamination of the dishes and utensils by the hot air. Summary of the Invention

[0004] The purpose of this invention is to provide a drying tank that can solve problems such as uneven drying effect, difficulty in draining water from the drying components, which affects normal use and causes bacteria to grow and contaminate tableware and kitchenware.

[0014] And / or, a support member is provided in the groove, the support member being used to support the heating element.

[0015] As an alternative to the aforementioned drying water tank, the inner wall of the drying air passage is provided with a lifting section downstream of the drain hole, and the end of the heating element opposite to the windward side is placed in the lifting section.

[0016] As an alternative to the aforementioned drying tank, the lifting section includes at least two spaced-apart lifting blocks, with a water passage hole formed between two adjacent lifting blocks.

[0017] As an alternative to the aforementioned drying tank, the drying air duct includes:

[0018] A heating air duct is provided at the bottom of the water tank, the heating element is provided inside the heating air duct, and the drain hole is connected to the heating air duct;

[0019] The bowl drying air duct extends from bottom to top and is located on one side of the water tank. The bottom end of the bowl drying air duct is connected to the heating air duct, and the top end of the bowl drying air duct is connected to the air outlet structure.

[0020] As an alternative to the aforementioned drying tank, a flow guide structure is provided at one end of the bowl drying air duct that connects to the heating air duct. The flow guide structure is used to guide water flow to the heating air duct.

[0021] As an alternative to the aforementioned drying tank, the air outlet structure includes an air outlet channel extending downward at an angle;

Detailed Implementation

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0049] like Figure 1 and Figure 2 As shown, this embodiment provides a drying sink, including a sink 100 and a dish rack assembly 200. The dish rack assembly 200 can be placed inside the sink 100, and is used to place tableware, kitchen utensils, and other items to facilitate draining water.

[0050] To facilitate users in washing tableware, kitchen utensils, or food, the sink body 110 is equipped with a faucet (not shown in the figure), which is connected to the indoor water system for user convenience.

[0051] In some embodiments, the dish basket assembly 200 is movable within and removed from the sink 100 to adjust its position or remove it according to the user's actual needs, thereby better meeting the user's usage requirements.

[0052] To improve the drying efficiency of tableware or kitchen utensils within the dish rack assembly 200, the drying sink also includes a drying component 300. The sink 100 includes a sink body 110 and an air outlet structure 120, which is mounted on the sink body 110. The dish rack assembly 200 is connected to the air outlet structure 120. The drying component 300 provides drying airflow and is connected to the air outlet structure 120. When the drying component 300 is activated, the drying airflow provided by the drying component 300 is blown into the dish rack assembly 200 through the air outlet structure 120 to dry the tableware, kitchen utensils, and other items within the dish rack assembly 200, thereby improving drying efficiency and preventing the tableware, kitchen utensils, and other items from growing bacteria in a humid environment for extended periods.

[0053] like Figure 3 As shown, the drying assembly 300 includes a drying air path, a heating element 320 disposed in the drying air path, and a fan 330. The fan 330 is used to drive the airflow in the drying air path, and the heating element 320 is used to heat the airflow to form hot air. The drying air path is connected to the air outlet structure 120 so that the hot air can be blown to the dish rack assembly 200 through the air outlet structure 120 to dry the tableware, kitchen utensils, etc. in the dish rack assembly 200.

[0054] Optionally, the heating element 320 can 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.

[0055] When users actually use the faucet, the water outlet angle and water flow will vary depending on the actual needs. This can cause 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 that enters the drying component 300 cannot be discharged. The water remains in the drying component 300 for a long time, which can easily lead to the growth of bacteria in the drying component 300, thereby contaminating tableware, kitchen utensils, etc. through hot air.

[0056] To address the aforementioned issues, in this embodiment, the air outlet structure 120 is designed to outlet air at an angle downwards. This serves two purposes: firstly, it prevents water from entering; even if some water does enter the air outlet structure 120, it will flow downwards under gravity, preventing water from entering the drying assembly 300. Secondly, the drying airflow flows towards the bottom of the dish rack assembly 200, and after contacting the bottom surface of the dish rack assembly 200, it deflects back and flows upwards due to its own characteristics, ensuring full contact with the tableware, kitchen utensils, and other items inside the dish rack assembly 200. This improves drying uniformity and enhances the user experience.

[0057] To prevent some water from entering the drying air duct and being unable to drain, in this embodiment, as follows: Figure 4 As shown, a drain 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 drain hole 3121. The drain hole 3121 is located below the heating element 320, and at least the bottom end of the air-facing side of the heating element 320 is sealed to the drying air duct, thereby preventing the drying airflow passing through the heating element 320 from entering below the heating element 320, thereby preventing the drying airflow from being discharged through the drain hole 3121, and thus reducing heat and airflow loss.

[0058] In addition, by placing the drain hole 3121 below the heating element 320, when the amount of water entering the drying air passage is small, the water marks remaining on the inner wall of the drying air passage are easier to dry. Some of the water flows to the heating element 320 and can be dried by the heat or residual temperature of the heating element 320, thus reducing the actual water discharged.

[0059] It should be noted that the windward side of the heating element 320 refers to the side of the heating element 320 facing the air intake direction of the drying air passage. By sealing the bottom surface of the windward side of the heating element 320 with the drying air passage, the airflow passing through the heating element 320 is ensured to pass through the interior or top of the heating element 320, thus preventing airflow from escaping through the drain hole 3121 while ensuring sufficient heat exchange with the heating element 320, thereby reducing airflow and heat loss.

[0060] In this embodiment, the downward-sloping air outlet structure 120 prevents water from entering the drying assembly 300, thus preventing water ingress. The drainage hole 3121 ensures that even if some water enters the drying assembly 300, it can drain away, preventing the long-term presence of water and bacterial growth, and thus preventing secondary contamination of tableware. Furthermore, the sealed fit between the bottom surface of the heating element 320's airflow and the drying air path prevents the drying airflow from entering below the heating element 320 and discharging through the drainage hole 3121, thus preventing heat and flow loss and ensuring drying efficiency.

[0061] This drying sink improves the drying effect on items in the dish rack assembly, keeping them dry and clean, which helps create a healthy kitchen environment.

[0062] To improve the drying effect, in some embodiments, combined with Figure 5 and Figure 6As shown, the dish rack assembly 200 includes a dish rack box and a dish rack 230 disposed inside the dish rack box. The dish rack box includes a box body 220 and a box lid 210. The dish rack 230 is used to hold tableware, kitchen utensils and other items. The dish rack box is provided with a vent 221, which is connected to the air outlet structure 120 so that the drying airflow can enter the dish rack box, which is conducive to concentrating the drying airflow and making full use of the heat of the drying airflow to dry tableware, kitchen utensils and other items.

[0063] To facilitate the drainage of water from tableware, kitchen utensils, and other items, the bottom of the cabinet 220 is equipped with drainage holes. Water dripping from tableware, kitchen utensils, and other items can be drained through the drainage holes to ensure that the inside of the dish rack is dry.

[0064] To achieve downward-sloping airflow, thereby preventing water from entering and improving drying efficiency, some embodiments, such as Figure 6 As shown, the air outlet structure 120 includes a downwardly extending guide channel. The guide channel can guide the drying airflow toward the bottom of the basket box on the one hand, and intercept water entering it on the other hand, so that the water flows out of the air outlet structure 120 under the action of gravity, thereby preventing water from entering the drying component 300.

[0065] Optionally, the internal flow channels of the air outlet structure 120 can all extend downwards at an angle, or as follows: Figure 6 As shown, the air outlet structure 120 also includes a horizontal flow channel connected to the guide flow channel. The horizontal flow channel is located at one end of the guide flow channel near the interior of the water tank body 110, which can also serve to waterproof and guide the drying airflow.

[0066] In some other embodiments, the air outlet structure 120 includes an air outlet and a guide plate disposed on the front side of the air outlet, the guide plate extending obliquely from top to bottom towards the front side of the air outlet. By providing the guide plate, on the one hand, the air outlet can be blocked on the front side to prevent water from entering the air outlet, and on the other hand, it can guide 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 blowing 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 blowing 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 tilt downward under the guidance of the air guide plate.

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

[0069] To improve airflow uniformity, in some embodiments, such as Figure 7 and Figure 8 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 divide the airflow in the guide channel into at least two paths, which is beneficial for uniform air outlet.

[0070] Optionally, the number of diverter plates 123 can be set to at least two, with at least two diverter plates 123 spaced apart, to improve the uniform airflow effect.

[0071] To facilitate maintenance of the air outlet structure 120, the air outlet structure 120 and the water tank body 110 can be detached and 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 component 121, which passes through the side wall of the sink body 110 and is detachably connected to the sink body 110. The air outlet component 121 passes through the sink body 110, which facilitates communication between the air outlet component 121 and the drying assembly 300 and the dish rack assembly 200 located inside the sink body 110, thereby simplifying the structure.

[0073] Optionally, the air outlet 121 is snapped into the water tank body 110, which facilitates the disassembly and assembly of the air outlet 121 and reduces the assembly difficulty.

[0074] In some embodiments, such as Figure 2 , Figure 6 and Figure 7 As shown, a support portion 111 protrudes from the inner wall of the sink body 110. The support portion 111 supports the dish basket assembly 200, and the air outlet 121 is connected to the support portion 111. By setting the support portion 111, on the one hand, the dish basket assembly 200 can be supported, simplifying the way the dish basket assembly 200 and the sink body 110 are matched. On the other hand, the protruding support portion 111 can provide sufficient installation space for the air outlet 121 to ensure that the air outlet 121 has sufficient air outlet length to ensure the length and tilt angle of the guide channel, thereby ensuring the waterproof effect and downward tilting air outlet effect of the air outlet structure 120.

[0075] Specifically, the inner walls on both sides of the water tank body 110 are provided with support parts 111, and the opening of the box body 220 is provided with a support flange. The support flange can be attached to the support parts 111 so as to suspend the box body 220 in the water tank body 110.

[0076] In some embodiments, such as Figure 7 As shown, the support part 111 is a horizontally extending strip, and the support flange of the box body 220 can overlap the support part 111 and slide along the support part 111 to adjust the position of the bowl assembly 200 in the sink body 110.

[0077] In some embodiments, combined with Figure 6 As shown, the sidewall of the water tank body 110 bends inward to form a protruding support portion 111 on the inner side of the water tank body 110, and a receiving groove is formed on the outer side of the water tank body 110, with at least a portion of the air outlet component 121 located within the receiving groove. Forming the support portion 111 by bending the sidewall of the water tank body 110 is convenient to process and requires no additional connecting structures, resulting in a simple structure. Forming the receiving groove simultaneously with the support portion 111 provides sufficient installation space for the air outlet component 121, preventing the air outlet component 121 from protruding entirely from the water tank body 110 and affecting the overall assembly. It also helps ensure that the air outlet component 121 has a certain air outlet length, improving the guiding effect on the downward-sloping airflow.

[0078] To avoid water residue on the support portion 111, in some embodiments, the top surface of the support portion 111 is inclined so that water dripping onto the support portion 111 can flow under the action of gravity, thus avoiding long-term accumulation on the support portion 111.

[0079] In some embodiments, the bottom surface of the support portion 111 is inclined so that water that slides down the bottom surface of the support portion 111 can flow to the lower end under the action of gravity, thereby converging and dripping down.

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

[0081] like Figure 8 As shown, in some embodiments, the air outlet 121 includes an air outlet pipe 1211 and a snap-fit ​​flange 1212 connected to the air outlet pipe 1211. A flow guide channel is formed inside the air outlet pipe 1211, and the air outlet pipe 1211 passes through the side wall of the water tank body 110. The snap-fit ​​flange 1212 is connected to one end of the air outlet pipe 1211 that extends into the water tank body 110, and the snap-fit ​​flange 1212 abuts against the inner wall of the water tank body 110 to prevent the air outlet pipe 1211 from detaching from the water tank body 110.

[0082] Optionally, the air outlet duct 1211 is interference-fitted with the water tank body 110 to achieve fixation, without the need for additional fixing structure, making installation convenient.

[0083] In some embodiments, a sealing element 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, preventing air leakage through the gap and also preventing water from flowing out through the gap.

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

[0085] 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 air path and a rear air path, which are connected by the heat exchange channel 322. This arrangement, combined with the bottom surface of the air-facing side of the heating element 320 sealingly fitting with the drying air path, ensures that all gas entering the front air path passes through the heat exchange channel 322 into the rear air path. This improves the heating effect on the airflow and prevents gas in the front air path from entering below the heating element 320 and passing through the drain hole 3121, thus reducing airflow loss.

[0086] In order to achieve a sealed fit between the bottom surface of the air-facing side of the heating element 320 and the drying air passage, in some embodiments, the bottom surface of the air-facing side of the heating element 320 is provided with a first mating surface, and the inner wall of the drying air passage includes a second mating surface. The first mating surface and the second mating surface are parallel and abut against each other to achieve a surface-to-surface fit, thereby reducing the gap between the first mating surface and the second mating surface and preventing airflow from passing through, thus achieving a sealing function.

[0087] Optionally, the first mating surface can be a plane or a curved surface, as long as the fit between the first mating surface and the second mating surface can be guaranteed.

[0088] It is understandable that even if there is a small gap between the first mating surface and the second mating surface, since the heat exchange channel 322 connects the front air passage and the rear air passage, the airflow has low resistance when passing through the heat exchange channel 322, but high resistance when passing through the gap between the first mating surface and the second mating surface. This causes the airflow to flow into the heat exchange channel 322. Therefore, the sealing fit between the bottom surface of the heating element 320 on the windward side and the drying air passage can be achieved by using a surface-to-surface fit.

[0089] 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.

[0090] To guide the airflow through the heat exchange channel 322, the inner wall of the drying air path also includes a guide surface 31221 connected to the second mating surface. The guide surface 31221 is located upstream of the second mating surface along the airflow direction, and its height gradually increases along the airflow direction. The airflow in the front section of the air path will flow upward under the guidance of the guide surface 31221, thus entering the heat exchange channel 322.

[0091] In addition, by setting the air guide surface 31221, the position height of the heating element 320 can be raised. On the one hand, this prevents the heating element 320 from contacting the water below, and on the other hand, it provides sufficient space for drainage by moving the heating element 320 upward.

[0092] To improve drainage, in some embodiments, the inner bottom surface of the drying air path is recessed to form a groove, and the drain hole 3121 is located on the bottom surface of the groove. By setting the groove, sufficient buffer space can be provided for drainage, avoiding water contact with the heating element 320 due to excessive water intake and insufficient drainage capacity; the drain hole 3121 is located in the low-lying groove, which facilitates the flow of water entering the drying air path to the drain hole 3121.

[0093] Alternatively, the groove can be formed by bending the inner wall of the drying air passage, thereby forming a groove on the inner side of the drying air passage and a protruding structure on the outer side of the drying air passage. The processing technology is simple, the molding is convenient, and it helps to reduce costs.

[0094] To improve the sealing effect between the air-facing side of the heating element 320 and the drying air path, a partition 31223 is provided in the groove. The partition 31223 divides the groove into a drainage groove 31225 and a sealing groove 31224. The sealing groove 31224 and the drainage groove 31225 are arranged along the airflow direction in the drying air path. That is, the sealing groove 31224 is located upstream of the drainage groove 31225 along the airflow direction. The drainage hole 3121 is provided on the bottom surface of the drainage groove 31225. The top surface of the partition 31223 abuts against the heating element 320 to achieve a sealing effect. By abutting the first mating surface and the second mating surface, and by abutting the partition 31223 against the heating element 320, a double seal can be achieved, thereby preventing the drying airflow from being discharged through the drainage hole 3121, reducing heat loss and flow loss.

[0095] 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.

[0096] 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 water leakage groove 31225 can be separated into two non-connected grooves.

[0097] In some other embodiments, the sealing between the windward side of the heating element 320 and the drying air passage can be achieved solely by the first mating surface and the second mating surface, or solely by the partition plate 31223 abutting against the heating element 320.

[0098] Since the heating element 320 is positioned above the groove, in order to ensure the stability of the heating element 320, in some embodiments, a support is provided in the groove. The support is used to support the heating element 320 to improve the positional stability of the heating element 320.

[0099] Optionally, the support portion can be disposed in at least one of the sealing groove 31224 and the water leakage groove 31225, both of which can improve the support effect on the heating element 320.

[0100] like Figure 10 As shown, a lifting part 31222 is provided on the inner wall of the drying air passage downstream of the drain hole 3121. The lifting part 31222 is used to support the end of the heating element 320 opposite to the windward side, so as to raise the height of the heating element 320 and prevent the water entering the drying air passage from contacting the heating element 320 during the process of flowing to the drain hole 3121.

[0101] To ensure that water can flow out through the drain hole 3121, the lifting part 31222 includes at least two lifting blocks, with adjacent lifting blocks spaced apart to form a water passage hole. Water entering the drying air passage can flow into the groove through the water passage hole and be discharged through the drain hole 3121.

[0102] In some embodiments, such as Figure 9 and Figure 11 As shown, the drying air path includes a connected heating air duct 3122 and a bowl drying air duct 3112. The heating element 320 is disposed in the heating air duct 3122, and the drain hole 3121 is connected to the heating air duct 3122. The bowl drying air duct 3112 is connected to the air outlet structure 120, and the heating air duct 3122 is located upstream of the bowl drying air duct 3112. The heating air duct 3122 is located at the bottom of the water tank 100 to utilize the waste heat of the heating air duct 3122 to dry the water tank 100. The bowl drying air duct 3112 extends from bottom to top and is located on one side of the water tank 100, so that the hot air heated by the heating air duct 3122 can enter the bowl drying air duct 3112 and flow upward under its own characteristics, reducing heat and air volume loss.

[0103] Understandably, if water enters the drying air duct, the water flows in the opposite direction to the hot air. The water that enters the drying air duct 3112 of the bowl basket through the air outlet structure 120 will flow from top to bottom under its own gravity, and thus enter the heating air duct 3122 at the bottom of the water tank 100 along the drying air duct 3112, so as to flow out through the drain hole 3121, which is conducive to drainage.

[0104] In order to allow water in the drying duct 3112 to enter the heating duct 3122, in some embodiments, a guide structure is provided at one end of the drying duct 3112 that connects to the heating duct 3122. The guide structure is used to guide the water flow to the heating duct 3122.

[0105] In some embodiments, the flow guiding structure is a flow guiding surface that slopes downwards toward the heating air duct 3122 to guide water flow toward the heating air duct 3122. Optionally, the flow guiding surface can be an arc surface to reduce corners and avoid water residue at corners; the flow guiding surface can also be a slope.

[0106] In some embodiments, the flow guiding structure can be a flow guiding rib that extends toward the heating air duct 3122 to guide the flow direction of the water, thereby guiding the water to the heating air duct 3122.

[0107] Combination Figure 3 , Figure 9 and Figure 11 As shown, the drying assembly 300 includes an air duct shell 310, which includes a side air duct shell 311 and a bottom air duct shell 312. The side air duct shell 311 is provided with an inlet air duct 3111 and a bowl drying air duct 3112. The bottom air duct shell 312 is provided with a connecting air duct 3123 and a heating air duct 3122. The inlet air duct 3111, the connecting air duct 3123, the heating air duct 3122, and the bowl drying air duct 3112 are connected in sequence. When drying the bowl assembly 200, the airflow enters the heating air duct 3122 through the inlet air duct 3111 and the connecting air duct 3123. After being heated by the heating element 320 of the heating air duct 3122, hot air is formed. The hot air enters the bowl drying air duct 3112 and is then blown towards the bowl assembly 200 by the air outlet structure 120.

[0108] Optionally, the air inlet duct 3111 extends from top to bottom, that is, the airflow 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 duct 3123 through the first connecting port 3113; the heating duct 3122 is connected to the drying basket assembly 200 through the second connecting port 3114.

[0109] In some embodiments, the air passage located in the bottom air duct shell 312 is curved and extended, so that dust and other impurities entering the air inlet duct 3111 with the airflow enter the bottom air duct shell 312 under the action of gravity and airflow. They are then deposited in the bottom air duct shell 312 through the meandering flow of airflow, thereby reducing the entry of dust and other impurities into the dish rack drying air duct 3112 and avoiding secondary contamination of the tableware or kitchen utensils in the dish rack assembly 200.

[0110] Optionally, at least one of the ventilation duct 3123 and the heating duct 3122 is bent, and / or the airflow direction at the connection position of the ventilation duct 3123 and the heating duct 3122 is set at an angle, so that the air path located in the bottom duct shell 312 is bent.

[0111] In some embodiments, the connecting ventilation duct 3123 is located above the heating ventilation duct 3122, and at least part of the first connecting port 3113 is directly opposite the heating ventilation duct 3122, so that part of the airflow passing through the first connecting port 3113 will hit the outer wall of the heating ventilation duct 3122 and change the flow direction, flowing upward into the connecting ventilation duct 3123, which is conducive to the deposition of dust and other impurities.

[0112] In addition, the airflow in the ventilation duct 3123 needs to change its flow direction at the end and flow downwards, so as to enter the heating duct 3122. The airflow direction changes again, which is conducive to the deposition of dust and other impurities.

[0113] In some embodiments, the drying tank also includes a control component 400, which is disposed on the top of the tank 100 and electrically connected to the drying component 300 to control the start and stop of the drying component 300 and its operating parameters.

[0114] It should be noted that the control component 400 is existing technology in this field. This embodiment can use any structure of the control component 400 in the prior art, which will not be described in detail here.

[0115] Optionally, the air inlet of the drying air duct is located on the control component 400 so that the airflow entering the drying air duct is clean air from outside the cabinet, avoiding the intake of humid air from inside the cabinet and causing secondary pollution to tableware or kitchen utensils.

[0116] In some embodiments, when the dish rack assembly 200 is disposed inside the sink body 110, the bottom surface of the box 220 is spaced apart from the inner bottom surface of the sink body 110, so that the box 220 is suspended inside the sink body 110. This facilitates the dripping of water inside the box 220 through the drain hole and its flow along the inner wall of the sink body 110, thereby being discharged from the drain outlet on the sink body 110. It also facilitates the flow of air inside the dish rack through the drain hole, which is beneficial for the airflow inside and outside the dish rack, thereby improving the drying efficiency and preventing the growth of bacteria inside the dish rack.

[0117] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
