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 in a humid environment, natural dish draining is inefficient, and dishes are often kept in a humid environment, which can easily breed bacteria. Therefore, drying sinks have emerged in the industry, combining sinks with drying components. However, drying components generally only dry the dish basket, or only the sink.

[0004] In solutions where the drying component only dries the dish basket, an air outlet is provided on the sink that blows air toward the dish basket. The air outlet is connected to the drying component, and the hot air provided by the air outlet dries the tableware and kitchenware in the dish basket. This type of drying sink can only dry the tableware and kitchenware in the dish basket, but cannot dry the sink itself. As a result, the sink is in a humid environment and cannot dry out in time, which can easily lead to bacterial growth and mold, affecting the dish basket inside the sink, resulting in secondary contamination of the dishware and other items in the basket. In solutions where the drying component only dries the sink, the drying component only heats the sink itself and cannot dry the dish basket, resulting in slow drying of the dishware and other items in the basket and low drainage efficiency. Summary of the Invention

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0055] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0056] 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.

[0057] 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 the convenience of users.

[0058] 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.

[0059] To keep the drying tank dry and clean, Figure 3As shown, the drying sink also includes a drying assembly 300. A heating chamber 3120 is formed within the drying assembly 300 and is located below the sink 100. The heating chamber 3120 is capable of providing hot air, heating the sink 100 and blowing air toward the basket assembly 200 to dry both the sink 100 and the basket assembly 200. Because the heating chamber 3120 is located below the sink 100, it can utilize the heat from the hot air to heat the sink 100, thereby drying the sink 100 and preventing mold or bacterial growth from prolonged exposure to humidity. The heating chamber 3120 can also provide hot air into the basket assembly 200 to dry items such as tableware and kitchenware within the basket assembly 200.

[0060] The drying sink can heat the sink 100 and dry the bowl basket assembly 200. The hot air for drying the bowl basket assembly 200 is generated by a heating chamber 3120 located below the sink 100. When drying the bowl basket assembly 200, the heat remaining in the heating chamber 3120 can continue to dry the sink 100, thereby improving heat utilization. This eliminates the need for two drying assemblies to dry the bowl basket assembly 200 and the sink 100 separately, reducing costs and ensuring a dry, clean drying sink, creating a healthy kitchen environment.

[0061] In this embodiment, the heating chamber 3120 is provided to provide hot air to dry the bowl-basket assembly 200 and the sink 100 to prevent the sink 100 or the bowl-basket assembly 200 from becoming moldy or breeding bacteria.

[0062] In some embodiments, such as Figure 2 As shown, the sink 100 includes a sink body 110 and an air outlet structure 120. The air outlet structure 120 is disposed on the sink body 110 and is in communication with the heating chamber 3120. When the basket assembly 200 is placed in the sink body 110, the basket assembly 200 communicates with the air outlet structure 120, allowing hot air generated in the heating chamber 3120 to enter the basket assembly 200 through the air outlet structure 120.

[0063] It is understandable that when the bowl basket assembly 200 is not placed in the sink body 110, if the drying assembly 300 is started, hot air can be blown into the sink body 110 through the air outlet structure 120, and cooperate with the bottom heating cavity 3120 to dry the sink body 110, thereby improving the drying efficiency.

[0064] like Figure 3 As shown, a heating element 320 and a fan 330 are provided in the heating chamber 3120. The heating element 320 is used to heat the gas in the heating chamber 3120 to form hot air, and the fan 330 is used to drive the hot air flow to achieve the purpose of drying the water tank 100 or the bowl basket assembly 200.

[0065] 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.

[0066] like Figure 4 As shown, a heating air duct 3122 and a tank drying air duct 3124 are provided in the heating chamber 3120, and the heating element 320 is provided in the heating air duct 3122 to generate hot air; the end of the heating air duct 3122 can be connected to the tank drying air duct 3124, so that the hot air enters the tank drying air duct 3124, so as to fully exchange heat with the water tank 100 and achieve the purpose of drying the water tank 100.

[0067] In some embodiments, both ends of the trough body drying air duct 3124 are connected to the heating air duct 3122 to form a circulating flow channel. The air flow entering the trough body drying air duct 3124 flows back to the heating air duct 3122 for heating and then enters the trough body drying air duct 3124 again, thereby improving the heat utilization rate and improving the drying effect of the water tank body 110 through the circulating flow channel; in addition, the trough body drying air duct 3124 is connected to the heating air duct 3122 to form a circulating flow channel, and no exhaust is required when drying the water tank 100, which can simplify the structure, reduce costs, and avoid exhaust causing unstable air pressure inside the cabinet where the water tank 100 is installed.

[0068] In order to increase the effective heat exchange area of ​​the tank drying air duct 3124 to the bottom of the water tank 100, the tank drying air duct 3124 includes a connected direct current zone 31241 and a recirculation zone 31242. The direct current zone 31241 is connected to the end of the heating air duct 3122, and the recirculation zone 31242 is connected to the head end of the heating air duct 3122. The flow directions of the airflow in the direct current zone 31241 and the recirculation zone 31242 are set at an angle to realize the reflux of the airflow in the tank drying air duct 3124 to the heating air duct 3122 without increasing the size of the heating air duct 3122.

[0069] It should be noted here that, Figure 4 The center line a is the boundary line between the DC area 31241 and the recirculation area 31242. Line a is an auxiliary schematic line for convenient explanation of the DC area 31241 and the recirculation area 31242, and is not a structural contour line.

[0070] To ensure uniform temperature in the water tank 100, in some embodiments, a first flow guide structure is provided within the drying air duct 3124 of the tank body. The first flow guide structure is configured to guide the airflow in the direct flow area 31241 into the recirculation area 31242 after deflection, and to cause the airflow in the direct flow area 31241 to flow in a straight line. The straight flow of air in the direct flow area 31241 provides low resistance, high flow velocity, and reduced eddy currents, resulting in even airflow distribution and, in turn, uniform heating of the water tank 100.

[0071] In some embodiments, along the flow direction of the airflow, the width of at least part of the direct current zone 31241 gradually increases, so as to further reduce the airflow resistance, so that the airflow can flow quickly in the direct current zone 31241 and achieve the effect of full diffusion; and the direct current zone 31241 has a large area, which can increase the effective heat exchange area with the water tank 100, and the heat exchange effect is good, which is conducive to uniform heating of the water tank 100, so as to achieve uniform and rapid temperature increase over a large area of ​​the water tank body 110.

[0072] In some embodiments, the width of the recirculation zone 31242 gradually decreases along the flow direction of the airflow. It is understood that the temperature of the drying airflow in the direct flow zone 31241 is greater than the temperature of the drying airflow in the recirculation zone 31242. To improve the uniformity of the temperature rise of the water tank body 110, the gradual contraction of the recirculation zone 31242 can gradually converge the airflow in the recirculation zone 31242 and slow down the airflow flow rate, thereby improving the heat exchange between the airflow in the recirculation zone 31242 and the water tank body 110, thereby increasing the temperature of the water tank body 110 at the corresponding position of the recirculation zone 31242, and thus achieving a uniform temperature rise of the water tank body 110.

[0073] In order to improve the temperature rise rate and temperature uniformity of the water tank body 110, the projected area of ​​the direct current zone 31241 on the horizontal plane is larger than the projected area of ​​the recirculation zone 31242 on the horizontal plane, so as to increase the effective heat exchange area between the direct current zone 31241 and the water tank body 110, and ensure that most positions of the water tank body 110 can be rapidly and evenly heated under the action of the airflow in the direct current zone 31241.

[0074] In some embodiments, the ratio of the projected area of ​​the DC zone 31241 on the horizontal plane to the projected area of ​​the heating chamber 3120 on the horizontal plane is greater than or equal to 60%, preferably greater than or equal to 70%. The larger the projected area of ​​the DC zone 31241, the larger the area of ​​the airflow will maintain a straight line flow after entering the DC zone 31241 from the heating duct 3122, which is conducive to ensuring uniform heating.

[0075] Exemplarily, typical but non-limiting values ​​of the ratio of the projected area of ​​the DC zone 31241 on the horizontal plane to the projected area of ​​the heating chamber 3120 on the horizontal plane are 60%, 65%, 70%, 75% or 80%.

[0076] It is understandable that, since the air flow resistance in the DC zone 31241 is small and the flow velocity is fast, the temperature of this part of the air flow is relatively high. In order to increase the temperature of the corresponding position of the water tank body 110 and the DC zone 31241, as shown in FIG. Figure 5As shown, a heat insulating member 314 is also provided between the DC zone 31241 and the water tank 100. The heat insulating member 314 can prevent the local temperature of the corresponding position of the water tank body 110 and the DC zone 31241 from being too high, so as to improve the uniformity of the heating temperature, and at the same time prevent the user from touching the water tank body 110 and getting burned.

[0077] Optionally, the heat insulating member 314 may be a heat insulating board, which is laid flat above the direct current zone 31241 and has a larger area to improve the heat insulating effect and prevent the local temperature of the water tank body 110 from being too high.

[0078] In some embodiments, the thermal insulation member 314 may be made of existing thermal insulation materials, such as ceramic fiberboard.

[0079] Optionally, the heat insulating plate may abut the bottom surface of the water tank body 110, or may be spaced apart from the bottom surface of the water tank body 110. Preferably, the heat insulating plate is spaced apart from the bottom surface of the water tank body 110 to form a first gap, which can prevent heat from the heat insulating plate from being directly transferred to the water tank body 110, thereby preventing the water tank body 110 from being overheated locally.

[0080] In some embodiments, the water tank body 110 is a generally rectangular tank, including a water tank bottom plate and water tank side plates arranged circumferentially around the water tank bottom plate. The water tank bottom plate is a rectangular plate, and the heating chamber 3120 is located below the water tank bottom plate, and the airflow and the water tank bottom plate cooperate in heat exchange. In other embodiments, the water tank body 110 can be a cylindrical tank body or other shapes.

[0081] To guide the airflow within the tank drying duct 3124, a first flow guide structure is provided within the tank drying duct 3124. This first flow guide structure is configured to deflect the airflow within the direct flow zone 31241 and direct it into the recirculation zone 31242, facilitating the return of the airflow within the tank drying duct 3124 to the heating duct 3122. Furthermore, the first flow guide structure directs the airflow within the direct flow zone 31241 to flow in a straight line, thereby reducing wind resistance, increasing air velocity, and improving the uniformity of the temperature rise within the tank body 110.

[0082] Among them, the deflection angle of the airflow in the direct flow zone 31241 when entering the recirculation zone 31242 can be set according to actual needs. For example, the deflection angle is less than or equal to 30 degrees to reduce the airflow velocity loss.

[0083] In some embodiments, the first guide structure includes a plurality of guide ribs, which are used to guide the flow of air to limit the flow direction of the air.

[0084] For example, Figure 4As shown, the guide ribs include a first rib 31243. The first rib 31243 extends linearly and is located within the direct current zone 31241. The first rib 31243 is used to guide the airflow within the direct current zone 31241 along a straight line. Optionally, multiple first ribs 31243 may be provided within the direct current zone 31241. These multiple first ribs 31243 divide the direct current zone 31241 into multiple air paths, further ensuring uniform heating of the water tank body 110.

[0085] In some embodiments, the distance between two adjacent first ribs 31243 gradually increases along the flow direction of the airflow in the direct current zone 31241 to reduce wind resistance and increase flow velocity.

[0086] In some embodiments, the guide ribs include a second rib 31245, which is disposed at the junction of the direct flow zone 31241 and the recirculation zone 31242. The second rib 31245 may be a curved plate to guide the airflow to change its direction and enter the recirculation zone 31242. The curved plate can gradually change the flow direction of the airflow and prevent turbulence. The second rib 31245 is disposed at the end of the direct flow zone 31241, that is, opposite the end of the direct flow zone 31241 that communicates with the heating duct 3122.

[0087] In some embodiments, the guide ribs include a third rib 31244 disposed in the recirculation zone 31242. The third rib 31244 is configured to guide airflow within the recirculation zone 31242. For example, the third rib 31244 can be a straight flat plate or an arc-shaped plate. Optionally, multiple third ribs 31244 can be provided within the recirculation zone 31242. Multiple third ribs 31244 divide the recirculation zone 31242 into multiple air paths, further ensuring uniform heating of the water tank body 110.

[0088] Optionally, the guide ribs can be integrally formed with the heating chamber 3120, or can be fixed to the inner wall of the heating chamber 3120 by welding or screw connection.

[0089] In some embodiments, the heat insulation plate and the guide rib plate are detachably connected to facilitate replacement of the heat insulation plate. For example, the top ends of the heat insulation plate and the guide rib plate are connected by screws.

[0090] like Figure 3 and Figure 6As shown, the drying assembly 300 further includes an insulating chamber 3130 located below the heating chamber 3120. The insulating chamber 3130 has an air outlet slit 3133 communicating with the outside world, which allows air to be discharged toward the circumferential sidewalls of the water tank 100. The insulating chamber 3130, located at the bottom of the heating chamber 3120, insulates the heating chamber 3120 and reduces heat loss. The hot air in the heating chamber 3120 raises the temperature of the air in the insulating chamber 3130, causing the hot air to flow upward. This causes the high-temperature air within the insulating chamber 3130 to flow toward the air outlet slit 3133, where it is discharged toward the circumferential sidewalls of the water tank 100, heating the circumferential sidewalls. This heats the bottom and circumferential sidewalls of the water tank 100, effectively utilizing the heat to improve the drying effect on the water tank body 110.

[0091] It can be understood that the insulation chamber 3130 is not connected to the heating chamber 3120. When the hot air enters the heating chamber 3120, part of the heat in the heating chamber 3120 is transferred toward the insulation chamber 3130, causing part of the gas in the insulation chamber 3130 to be heated and flow upward. The hot air will be discharged from the air outlet gap 3133 to heat the circumferential side wall of the water tank body 110.

[0092] The heat insulation cavity 3130 also has an air supply port connected to the outside. Under the action of heat convection, the air supply port is used to enter the heat insulation cavity 3130, and the air outlet slit 3133 is used to discharge air toward the water tank body 110. The location and number of the air supply port are not limited here.

[0093] To enhance the heating effect on the circumferential sidewalls of the water tank body 110, the air outlet slits 3133 extend around the circumference of the water tank body 110. The air outlet slits 3133 can be arranged around the water tank body 110 in a circle, i.e., an annular slit; or they can be arranged around the water tank body 110 in less than a circle. The air outlet slits 3133 can be arranged continuously or in multiple intervals around the water tank body 110.

[0094] In some embodiments, the flow area of ​​the air outlet slit 3133 gradually decreases along the air outlet direction of the air outlet slit 3133, so that the air flow can fully contact the circumferential side wall of the water tank body 110, thereby improving the heat exchange effect.

[0095] In some embodiments, combined Figure 3As 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.

[0096] In some embodiments, the air duct shell 310 includes a side air duct shell 311, a bottom air duct shell 312 and an insulation shell 313. The side air duct shell 311 is located on one side of the sink body 110, and the two form an air inlet duct 3111 and a bowl basket drying duct 3112; the bottom air duct shell 312 is located below the sink body 110, and forms a heating cavity 3120 with the sink body 110 to accelerate heat conduction and avoid heat loss; the insulation shell 313 is arranged below the bottom air duct shell 312, and forms an insulation cavity 3130 with the bottom air duct shell 312.

[0097] Optionally, the bottom air duct housing 312 includes a first bottom plate and a first side plate, wherein the first side plate is arranged around the circumference of the first bottom plate to enclose a heating chamber 3120 with the water tank body 110. The first side plate is connected to the water tank body 110 to fix the bottom air duct housing 312 to the water tank body 110.

[0098] To simplify the structure, the air outlet gap 3133 is not provided at the location where the side air duct shell 311 is provided on the outside of the water tank body 110 .

[0099] Optionally, the insulation shell 313 includes a second bottom plate 3131 and a second side plate 3132. The second side plate 3132 is arranged around the circumference of the second bottom plate 3131 to cooperate with the bottom air duct shell 312 to form an insulation cavity 3130. The second side plate 3132 extends upward and is higher than the bottom surface of the sink body 110, and forms an air outlet gap 3133 with the circumferential side wall of the sink body 110.

[0100] In some embodiments, the top end of the second side plate 3132 is tilted toward the water tank body 110 so that the flow area of ​​the air outlet gap 3133 gradually decreases, while also preventing foreign matter from falling into the air outlet gap 3133 .

[0101] Optionally, the first bottom plate is connected to the second bottom plate 3131 to fix the heat insulation shell 313 at the bottom air duct shell 312 to stabilize the structure.

[0102] For example, an insulating air duct is provided in the insulating cavity 3130, which guides the airflow in a zigzag direction toward the air outlet slit 3133. By providing the insulating air duct, the airflow path is extended, the airflow residence time in the insulating cavity 3130 is increased, and the heat preservation and heat exchange effect is improved.

[0103] Optionally, a rib plate is provided on the second bottom plate 3131 , and the rib plate and the first bottom plate form a heat-insulating air duct.

[0104] In some embodiments, an insulation member is provided within the insulation cavity 3130 to provide insulation and reduce heat loss. The insulation member can be made of existing insulation materials. The provision of the insulation member does not affect the airflow within the insulation cavity 3130. For example, the insulation member is configured to form an insulated air duct that zigzags airflow toward the outlet slit 3133.

[0105] In some embodiments, the drying assembly 300 further includes an air direction switching assembly, which can switch the blowing direction of the drying assembly 300, so that the drying assembly 300 can be switched to communicate with the air outlet structure 120, so that the air flow is blown toward the bowl basket assembly 200, thereby achieving the purpose of drying tableware, kitchen utensils and other items in the bowl basket assembly 200, or, as needed, the air flow generated by the drying assembly 300 is located in the heating chamber 3120 to flow, so as to heat the bottom of the water sink 100, thereby achieving the purpose of drying the inner wall of the water sink 100.

[0106] Specifically, if Figure 7 and Figure 8 As shown, the drying component 300 also includes a bowl basket drying duct 3112, which is connected to the air outlet structure 120. The wind direction switching component is arranged in the heating chamber 3120, and is used to selectively connect the air outlet end of the heating duct 3122 with the trough drying duct 3124 or the bowl basket drying duct 3112.

[0107] When the bowl basket assembly 200 is placed in the sink 100 and the tableware or kitchenware in the bowl basket assembly 200 needs to be dried, Figure 8 As shown, the drying assembly 300 is started, and the wind direction switching assembly connects the bowl basket drying duct 3112 and the heating duct 3122. The bowl basket drying duct 3112 is connected to the bowl basket assembly 200 through the air outlet structure 120. The 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, kitchen utensils and other items in the bowl basket assembly 200, thereby improving the drying efficiency and preventing the tableware, kitchen utensils and other items from being in a humid environment for a long time and breeding bacteria. When the inner wall of the sink 100 needs to be dried, as shown in FIG. Figure 4 As shown, the drying component 300 is started, the wind direction switching component connects the tank drying air duct 3124 and the heating air duct 3122, and the tank drying air duct 3124 exchanges heat with the bottom surface of the water tank body 110, thereby achieving the purpose of drying the water tank 100.

[0108] 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.

[0109] In some embodiments, a sterilization component is provided in the bowl basket drying duct 3112, and the sterilization component is used to sterilize the hot air to avoid secondary contamination of the items in the bowl basket assembly 200. Optionally, the sterilization component includes a sterilizing ultraviolet lamp.

[0110] To achieve selective communication between the heating air duct 3122 and the bowl-drying air duct 3112 or the tank-drying air duct 3124, in some embodiments, the heating air duct 3122 has a first air outlet 31226 and a second air outlet 3114. The first air outlet 31226 communicates with the tank-drying air duct 3124, while the second air outlet 3114 communicates with the bowl-drying air duct 3112. The drying assembly 300 also includes a reversing paddle 340 and a reversing drive. The reversing paddle 340 is movably disposed within the heating chamber 3120 and is switchable between a first position blocking the second air outlet 3114 and a second position blocking the first air outlet 31226. The output end of the reversing drive is connected to the reversing paddle 340, which is capable of driving the reversing paddle 340 to move relative to the heating chamber 3120 between the first position and the second position, thereby changing the flow direction of the drying airflow.

[0111] 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 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 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.

[0112] To facilitate the switching of the reversing paddle 340, the reversing paddle 340 is rotatably connected to the heating chamber 3120. The reversing drive can drive the reversing paddle 340 to rotate relative to the heating chamber 3120 to switch between the first position and the second position, simplifying the structure and reducing costs.

[0113] Optionally, the reversing drive member can be a rotary motor, and the output end of the rotary motor is connected to one end of the reversing paddle 340 to drive the reversing paddle 340 to rotate. Wherein, the rotary motor is arranged below the bottom air duct shell 312.

[0114] In order to ensure the reliability of switching the air outlet direction of the heating air duct 3122, in some embodiments, a first limiting portion is provided at the first air outlet 31226, and the first limiting portion can abut against the reversing paddle 340 located in the second position to prevent the reversing paddle 340 from continuing to move, so as to ensure the closing effect of the reversing paddle 340 on the first air outlet 31226.

[0115] In some embodiments, a second limiting portion is provided at the second air outlet 3114 , and the second limiting portion can abut against the reversing paddle 340 at the first position to ensure that the reversing paddle 340 has a closing effect on the second air outlet 3114 .

[0116] In some other embodiments, the reversing paddle 340 can be slidably connected to the heating chamber 3120 and can also be switched between the first position and the second position. Correspondingly, the first air outlet 31226 and the second air outlet 3114 are arranged along the sliding path of the reversing paddle 340.

[0117] In some embodiments, the bowl basket drying duct 3112 extends from bottom to top and is located on one side of the sink 100, so that the hot air heated by the heating duct 3122 can flow upward due to its own characteristics after entering the bowl basket drying duct 3112, thereby reducing heat and air volume loss.

[0118] 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.

[0119] 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.

[0120] In some embodiments, reference Figure 7 As shown, the air inlet duct 3111 extends from top to bottom. In other words, air enters from the top of the air inlet duct 3111, ensuring the integrity of the air intake and preventing secondary contamination of the tableware. Specifically, the airflow within the air inlet duct 3111 flows from top to bottom, and the bottom end of the air inlet duct 3111 is connected to the heating chamber 3120 through the first connecting port 3113.

[0121] In some embodiments, a control component 400 is provided on the top of the sink 100, and an air inlet is provided on the control component 400, which is connected to the air inlet duct 3111. On the one hand, the air flow entering the heating chamber 3120 is clean air from the outside of the cabinet, avoiding the inhalation of humid gas in the cabinet and causing secondary pollution to tableware or kitchen utensils; on the other hand, the external air flow can pass through the inside of the control component 400 before entering the heating chamber 3120 for heating, which can play a role in heat dissipation for the control component 400.

[0122] The control component 400 is electrically connected to the drying component 300 to control the start and stop and working parameters of the drying component 300. It should be noted that the control component 400 is a prior art in this field, and this embodiment can adopt any structure of the control component 400 in the prior art, which will not be repeated here.

[0123] 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.

[0124] It can be understood that the air inlet duct 3111 and the bowl basket drying duct 3112 both extend in the up-down direction, which can cooperate with the curved extension of the air path in the bottom duct shell 312 to improve the dust deposition effect.

[0125] like Figure 9 As shown, a connecting air duct 3123 is also provided in the heating chamber 3120, and the connecting air duct 3123 connects the heating air duct 3122 and the air inlet duct 3111. At least one of the connecting air duct 3123 and the heating air duct 3122 is bent, 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 flow in the heating chamber 3120 changes its flow direction when passing through the connecting air duct 3123 and the heating air duct 3122, which is conducive to the deposition of impurities such as dust.

[0126] In some embodiments, the connecting air duct 3123 is located above the heating air duct 3122, and at least part of the connecting port 3113 is directly opposite the heating air duct 3122, so that part of the airflow passing through the 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] In some embodiments, such as Figure 10 and Figure 11 As shown, the waterproof portion includes an air outlet flow channel, at least a portion of which extends obliquely downward in the air outlet direction so as to achieve 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 assembly 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.

[0131] Optionally, the air outlet channels in the air outlet structure 120 all extend downwardly, or as shown in FIG. Figure 11 As shown, only a portion of the air outlet channel extends obliquely, and a portion of the air outlet channel close to the bowl basket assembly 200 can extend horizontally, which can also play the role of waterproofing and guiding the drying air flow.

[0132] 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 of the air outlet channel 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 of the air outlet channel. The provision of the air deflector not only shields the air outlet from the front of the air outlet channel to prevent water from entering the air outlet channel, but also guides the airflow downward.

[0133] 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 passage to prevent water from entering the drying assembly 300 through the air outlet passage. When the air outlet passage is outputting air, the airflow acts on the air guide plate to push the air guide plate to rotate, thereby opening the air outlet passage and causing the airflow to be discharged obliquely downward under the guidance of the air guide plate.

[0134] In some other embodiments, the air outlet structure 120 includes an air outlet 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.

[0135] To improve the uniformity of air flow, in some embodiments, Figure 12 and Figure 13 As shown, the air outlet structure 120 includes an air outlet channel and a diverter plate 123 disposed in the air outlet channel. The diverter plate 123 can divert the airflow in the air outlet channel into at least two paths, which is conducive to uniform air outlet.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] In some embodiments, such as Figure 2 、 Figure 11-13As 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.

[0141] 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.

[0142] In some embodiments, such as Figure 12 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.

[0143] In some embodiments, combined Figure 11 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] like Figure 13 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.

[0148] 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.

[0149] 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.

[0150] Optionally, the sealing member 122 may be a sealing strip, which has a simple structure and good sealing effect.

[0151] In order to prevent some water from entering the drying air duct and being unable to be discharged, in this embodiment, Figure 14 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] In order to improve the drying effect, in some embodiments, Figure 2 and Figure 3 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.

[0156] In order to facilitate the drainage of water on items such as tableware and kitchen utensils, a drain hole is provided on the bottom surface of the box body 220. Water dripping from items such as tableware and kitchen utensils can be drained through the drain hole to ensure that the bowl basket box is dry.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] 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 .

[0171] 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 on the heating element 320.

[0172] like Figure 15 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.

[0173] 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.

[0174] 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.

[0175] 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 .

[0176] 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.

[0177] 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 .

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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.

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.
