Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, and in particular 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 constant dampness keeps the dishes moist, making them prone to bacterial growth. To address this, drying sinks have emerged in the industry. Dish baskets are placed inside the drying sink, which has air vents that blow air towards the baskets. These vents are connected to a drying unit, which provides hot air that dries the dishes and utensils inside the baskets. However, existing drying sinks only dry the baskets; they do not dry the sink itself. The dampness of the sink means that the dishes cannot dry quickly enough, leading to bacterial growth and mold, which can then contaminate the dishes inside the baskets. Utility Model Content

[0004] The purpose of this utility model is to provide a drying sink that can solve the problem of secondary contamination of tableware in the dish rack due to dampness in the sink.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] sink;

[0008] The dish basket assembly can be placed inside the water tank;

[0009] The drying assembly includes a drying air path and an air direction switching assembly. The air direction switching assembly is used to switch the air outlet direction so that the drying air path is connected to the dish basket assembly, or to heat the bottom outer wall of the water tank to dry the dish basket assembly or the water tank.

[0010] As an optional solution for the aforementioned drying tank, the drying air path includes a heating air duct, a bowl drying air duct, and a tank drying air duct. The heating air duct is used to provide hot air. The bowl drying air duct can be connected to the bowl assembly. The tank drying air duct is in heat exchange cooperation with the bottom of the tank. The air direction switching component can selectively connect the heating air duct to the bowl drying air duct or the tank drying air duct.

[0011] As an alternative to the above-mentioned drying tank, the heating air duct has a first air outlet and a second air outlet, the first air outlet being connected to the drying air duct of the tank body, and the second air outlet being connected to the drying air duct of the bowl basket.

[0020] And / or, the bowl drying air duct is located on one side of the water tank and the air flows from bottom to top.

[0021] As an alternative to the aforementioned drying tank, the drying assembly includes an air duct shell, which, together with the outer wall of the tank, forms the drying air path.

[0022] As an alternative to the aforementioned drying tank, the drying assembly further includes a heating element disposed within the drying air duct. A water leakage hole is provided on the bottom surface of the drying air duct below the heating element, and at least the bottom end of the heating element on the windward side is sealed to the drying air duct.

[0023] As an alternative to the above-mentioned drying water tank, the bottom surface of the heating element on the windward side is provided with a first mating surface, and the inner wall of the drying air passage includes a second mating surface, wherein the first mating surface is parallel to and abuts against the second mating surface;

[0024] And / or, the inner bottom surface of the drying air passage is recessed to form a groove, and a partition is provided in the groove.

[0040] 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 present 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, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. 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.

[0043] 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] 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.

[0045] To facilitate users in washing tableware, kitchen utensils, or food, a faucet (not shown in the figure) is installed on the sink body 110. The faucet is connected to the indoor water system for user convenience.

[0046] 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.

[0047] To prevent the drying sink from being damp for a long time and thus breeding bacteria or mold, the drying sink also includes a drying component 300. The drying component 300 includes a drying air path and an air direction switching component. The drying air path is used to provide drying airflow, and the air direction switching component can switch the air outlet direction of the drying air path so that the drying air path can be connected to the dish rack assembly 200, or to heat the bottom outer wall of the sink 100, so as to dry the dish rack assembly 200 or the sink 100 as needed.

[0048] When the dish rack assembly 200 is placed inside the sink 100, and it is necessary to dry the tableware or kitchen utensils inside the dish rack assembly 200, the drying assembly 300 is activated. The drying airflow is connected to the dish rack assembly 200, and the drying airflow provided by the drying assembly 300 blows into the dish rack assembly 200 to dry the tableware and kitchen utensils inside, improving drying efficiency and preventing bacteria growth due to prolonged exposure to a damp environment. When it is necessary to dry the inner wall of the sink 100, the drying assembly 300 is activated, and the drying airflow blows towards the bottom outer wall of the sink 100. The drying airflow exchanges heat with the bottom outer wall of the sink 100, heating the temperature of the sink 100, thereby achieving the purpose of drying the sink 100.

[0049] In this embodiment, the drying component 300 can dry both the dish rack component 200 and the sink 100, keeping them dry and clean, which is conducive to creating a healthy kitchen environment; moreover, the drying sink has a simple structure, which helps to reduce costs and improve product competitiveness.

[0050] In some embodiments, the water tank 100 includes a water tank body 110 and an air outlet structure 120, which is disposed on the water tank body 110, and the drying air path is connected to the air outlet structure 120. When the dish basket assembly 200 is disposed inside the water tank body 110, the dish basket assembly 200 is connected to the air outlet structure 120, so that the drying airflow in the drying air path can enter the dish basket assembly 200 through the air outlet structure 120.

[0051] like Figure 3 As shown, the drying assembly 300 also includes a heating element 320 and a fan 330 disposed in the drying air duct. The fan 330 is used to drive the airflow in the drying air duct, and the heating element 320 is used to heat the airflow to form hot air. The drying air duct 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 and the like in the dish rack assembly 200.

[0052] 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.

[0053] In some embodiments, such as Figures 4-7As shown, the drying air path includes a heating air duct 3122, a bowl drying air duct 3112, and a trough drying air duct 3124. A heating element 320 is disposed within the heating air duct 3122 to provide drying airflow. The bowl drying air duct 3112 is connected to the bowl assembly 200 via the air outlet structure 120. The trough drying air duct 3124 is heat-exchange coupled to the bottom of the water trough 100. The heating air duct 3122 is located upstream of the bowl drying air duct 3112. The airflow switching component can selectively connect the heating air duct 3122 to either the bowl drying air duct 3112 or the trough drying air duct 3124.

[0054] When the heating air duct 3122 is connected to the dish rack drying air duct 3112, the drying airflow in the heating air duct 3122 enters the dish rack drying air duct 3112 and enters the dish rack assembly 200 through the air outlet structure 120 to dry the tableware and kitchen utensils in the dish rack assembly 200.

[0055] When the heating air duct 3122 is connected to the tank drying air duct 3124, the drying airflow in the heating air duct 3122 enters the tank drying air duct 3124 to fully exchange heat with the bottom of the tank body 110, thereby drying the tank body 110 and keeping the tank body 110 dry, preventing the tank body 110 from becoming moldy or breeding bacteria due to moisture.

[0056] In some embodiments, the heating duct 3122 is located at the bottom of the water tank 100 to utilize the waste heat of the heating duct 3122 to dry the water tank 100 and improve heat utilization.

[0057] In some embodiments, 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 flow upward under its own characteristics after entering the bowl drying air duct 3112, reducing heat and air volume loss.

[0058] To improve the drying effect and facilitate the drying tank body 110, combined with Figure 3 , Figure 4 and Figure 6 As shown, the drying assembly 300 includes an air duct shell 310, which, together with the outer wall of the water tank body 110, forms a drying air path. This arrangement reduces the size and material usage of the air duct shell 310, lowering costs. Furthermore, the drying airflow within the drying air path directly contacts the water tank body 110, facilitating heat transfer to the water tank body 110 for drying, thus improving heat utilization and preventing heat waste.

[0059] 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 contains an inlet air duct 3111 and a dish rack drying air duct 3112. The bottom air duct housing 312 contains a connecting air duct 3123, a heating air duct 3122, and a trough drying air duct 3124. The inlet air 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 either the dish rack drying air duct 3112 or the trough drying air duct 3124. When drying the dish rack assembly 200, such as... Figure 7 As shown, the heating air duct 3122 is connected to the dish rack drying air duct 3112. 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 in the heating air duct 3122, hot air is generated and enters the dish rack drying air duct 3112, then is blown towards the dish rack assembly 200 by the outlet air structure 120. When it is necessary to dry the contents of the water tank body 110, such as... Figure 8 As shown, the heating air duct 3122 is connected to the tank drying air duct 3124. The airflow enters the heating air duct 3122 through the air inlet 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 tank drying air duct 3124 to heat the tank body 110 and achieve the purpose of drying the tank body 110.

[0060] It is understandable that the side air duct shell 311 and one side wall of the water tank body 110 form a bowl drying air duct 3112. The heat of the drying airflow in the bowl drying air duct 3112 is exchanged with the water tank body 110 through direct contact, which will heat the water tank body 110 and can achieve the purpose of drying the water tank body 110 to a certain extent.

[0061] Since the sink body 110 is generally embedded in the cabinet, at least part of the drying air path is located in the cabinet. On the one hand, the heat of the airflow in the drying air path can have a certain drying effect on the cabinet and reduce the humidity in the cabinet. On the other hand, the cabinet can prevent the heat from dissipating further, so as to reduce the instantaneous heat and improve the heat utilization rate.

[0062] To prevent airflow in the 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 drying duct 3124 is connected to the heating duct 3122 to form a circulation channel. The airflow entering the drying duct 3124 flows back to the heating duct 3122 for heating and then re-enters the drying duct 3124. The circulation channel improves the drying effect on the water tank body 110.

[0063] To enable 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 heating air duct 3122 has a first air outlet and a second air outlet 3114. The first air outlet is connected to the trough drying air duct 3124, and the second air outlet 3114 is connected to the bowl drying air duct 3112. The drying assembly 300 also includes a reversing lever 340 and a reversing drive. The reversing lever 340 is movably disposed within the drying air path and can switch between a first position blocking the second air outlet 3114 and a second position blocking the first air outlet. The output end of the reversing drive is connected to the reversing lever 340, and the reversing drive can drive the reversing lever 340 to move relative to the drying air path to switch between the first position and the second position, thereby changing the flow direction of the drying airflow.

[0064] Specifically, when the reversing lever 340 is in the first position, the heating air duct 3122 is connected to the drying air duct of the tank body, and the drying airflow enters the drying air duct 3124 of the tank body to dry the tank body 110; when the reversing lever 340 is in the second position, the heating air duct 3122 is connected to the drying air duct 3112 of the dish basket, and the drying airflow enters the dish basket assembly 200 through the dish basket drying air duct 3112 and the air outlet structure 120 to dry the tableware or kitchen utensils in the dish basket assembly 200.

[0065] To facilitate the switching of the position of the reversing lever 340, the reversing lever 340 is rotatably connected to the drying diversion. The reversing drive can drive the reversing lever 340 to rotate relative to the drying air path, so as to switch between the first position and the second position, simplifying the structure and reducing costs.

[0066] Optionally, the commutation drive can be a rotary motor, with the output end of the rotary motor connected to one end of the commutation lever 340 to drive the commutation lever 340 to rotate.

[0067] To ensure the reliability of the air outlet direction switching of the drying air duct, in some embodiments, a first limiting part is provided at the first air outlet. The first limiting part can abut against the reversing lever 340 located in the second position to prevent the reversing lever 340 from continuing to move, so as to ensure the closing effect of the reversing lever 340 on the first air outlet.

[0068] In some embodiments, a second limiting part is provided at the second air outlet 3114, which can abut against the reversing lever 340 at the first position to ensure the closing effect of the reversing lever 340 on the second air outlet 3114.

[0069] Since the end of the drying air duct 3124 is connected to the heating air duct 3122, the drying air duct 3124 includes a direct flow zone and a return flow zone. The direct flow zone is connected to the outlet section of the heating air duct 3122, and the return flow zone is connected to the inlet end of the heating air duct 3122. The airflow direction in the direct flow zone and the return flow zone is set at an angle to change the airflow direction and make the airflow return to the heating air duct 3122.

[0070] In order to improve the drying efficiency and heating uniformity of the water tank body 110, the width of the direct current zone gradually increases along the flow direction of the airflow, so that the drying airflow can flow quickly in the direct current zone and diffuse rapidly, so as to achieve uniform and rapid temperature rise of the water tank body 110 over a large area.

[0071] In some embodiments, the width of the recirculation zone gradually decreases along the airflow direction. It is understood that the temperature of the drying airflow in the direct flow zone is higher than that in the recirculation zone. To improve the uniformity of temperature rise in the water tank body 110, the gradual contraction of the recirculation zone allows the drying airflow in the recirculation zone to gradually converge and slow down the airflow velocity, thereby improving the heat exchange between the airflow in the recirculation zone and the water tank body 110, thus raising the temperature of the water tank body 110 at the corresponding location in the recirculation zone and ensuring a uniform temperature rise in the water tank body 110.

[0072] In some embodiments, 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 connecting port 3113.

[0073] 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.

[0074] 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.

[0075] In some embodiments, the connecting ventilation duct 3123 is located above the heating ventilation duct 3122, and at least part of the connecting port 3113 is directly opposite the heating ventilation duct 3122, so that part of the airflow passing through the 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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 contamination to tableware or kitchen utensils. Specifically, the air inlet is connected to the air inlet duct 3111.

[0080] 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.

[0081] In some embodiments, such as Figure 2 As shown, a support portion 111 protrudes from the inner wall of the sink body 110. The support portion 111 supports the dish rack assembly 200, and the air outlet structure 120 is disposed on the support portion 111. By providing the support portion 111, on the one hand, the dish rack assembly 200 can be supported, simplifying the way the dish rack 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 structure 120.

[0082] 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.

[0083] In some embodiments, the support portion 111 is 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 assembly 200 within the sink body 110.

[0084] 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.

[0085] 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.

[0086] In some other embodiments, the top and bottom surfaces of the support 111 may be inclined to improve the water diversion effect.

[0087] To prevent some water from entering the drying air duct and being unable to drain, in this embodiment, as follows: Figure 9 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.

[0088] 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.

[0089] 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.

[0090] 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 on its windward side and the drying airflow 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] To improve the drying effect, in some embodiments, combined with Figure 2 and Figure 3 As 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.

[0096] 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 cabinet remains dry.

[0097] In some embodiments, such as Figure 4 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] Optionally, the support member 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.

[0112] like Figure 5 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.

[0113] 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.
