Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and in particular to a disinfection device and a sink device. Background Technology

[0002] In kitchen hygiene scenarios, knives, cutting boards, and other kitchen utensils often retain moisture and bacteria after use, requiring them to be dried in a specific device. Existing disinfection devices consist of a disinfection chamber and a drying module, with a drain hole at the bottom of the disinfection chamber for wastewater discharge. To prevent wastewater from flowing into the drying module, a stepped structure is typically used between the drying module and the drain hole, meaning the air outlet of the drying module is higher than the drain hole.

[0003] However, if the drainage speed is slower than the water inflow speed, or if the drain outlet is blocked, the water level inside the cavity will gradually rise and eventually invade the drying module, causing electrical malfunctions such as short circuits in the heating element and damage to the fan, posing a safety hazard. Summary of the Invention

[0004] This invention provides a disinfection device and a water tank device, which aims to solve the technical problem of water backflow into the drying module and causing electrical damage due to untimely drainage during the cleaning and disinfection process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A disinfection device includes a main body and a drying module. The main body has a disinfection chamber and an air duct, an exhaust port and a drain port connected to the disinfection chamber. The exhaust port of the drying module is connected to the air duct.

[0007] The ventilation duct is equipped with a first water-proof structure, which includes a floating component and a first sealing component. The floating component rises or falls with the water level in the disinfection chamber to seal or detach from the first sealing component, thereby closing or opening the ventilation duct.

[0008] The air duct is also equipped with a second water-proof structure, which is located between the drying module and the first water-proof structure and is used to intercept water that leaks through the first water-proof structure.

[0009] Furthermore, the main body includes a box and an air duct component. The box is provided with a disinfection chamber and a drain outlet. The space enclosed by the box and the air duct component is connected to form an air passage. The side wall of the air duct component is provided with a protective wall that is recessed inward. The top of the protective wall is provided with a first ventilation opening. The drying module is connected to the air passage through the first ventilation opening. The protective wall constitutes a second leak-proof structure.

[0010] Furthermore, it also includes a third leak-proof structure, which includes an adapter and a second sealing element sleeved outside the adapter. The adapter is rotatably installed in the installation cavity enclosed by the protective wall, and the adapter is movably sealed to the inner wall of the installation cavity through the second sealing element.

[0011] The adapter is provided with a flow cavity and a second vent connected to the flow cavity. The air outlet of the drying module is connected to the flow cavity. The drying module is driven to the adapter. By rotating the drying module, the first vent and the second vent can be connected to each other or staggered.

[0012] Furthermore, the outer wall of the adapter is provided with a first positioning part, which is located on the rotation axis of the adapter. The inner wall of the protective wall facing the first positioning part is provided with a second positioning part, which cooperates with the recess of the first positioning part to limit the radial displacement of the adapter.

[0013] Furthermore, when the drying module is rotated and connected to the air duct component in the first direction, the first vent and the second vent are interconnected.

[0014] When the drying module rotates in the second direction and disengages from the air duct, the first vent and the second vent disconnect from each other, wherein the first direction and the second direction are opposite to each other.

[0015] Furthermore, the air duct is provided with a partition that divides the air duct into a first cavity and a second cavity. The partition has a connecting port that connects the first cavity and the second cavity. The side wall of the first cavity is provided with a protective wall. The second cavity is provided with a floating component and is connected to the disinfection cavity. The connecting port is provided with a first sealing component.

[0016] Furthermore, the floating component is a float, the radial dimension of which is greater than the radial dimension of the connecting port, and the distance between the opening of the connecting port and the inner wall of the second cavity is less than the radius of the float.

[0017] Furthermore, a buffer pad is provided at the bottom of the disinfection chamber.

[0018] Furthermore, the top of the main body is provided with a cover plate, which has several placement openings that connect to the disinfection chamber, and the placement openings constitute an exhaust vent.

[0019] A water tank device includes a tank body, the tank body having a receiving groove and an overlapping area located at the outer edge of the receiving groove, and also includes a disinfection device as described above, the overlapping area having a clearance opening for receiving the main body.

[0020] The beneficial effects of this invention are:

[0021] 1. The present invention proposes a disinfection device, comprising a main body and a drying module. The main body has a disinfection chamber and an air duct and an exhaust port connected to the disinfection chamber. The exhaust port of the drying module is connected to the air duct. The air duct is provided with a first leak-proof structure and a second leak-proof structure. The first leak-proof structure includes a floating component and a first sealing component. The second leak-proof structure is located between the drying module and the first leak-proof structure. By utilizing the buoyancy of the floating component as a driving force, it can automatically seal and adhere to the first sealing component to close the air duct when a water ingress risk occurs without external power control, thus preventing water from flowing into the drying module due to drainage failure. At the same time, the addition of the second leak-proof structure between the drying module and the first leak-proof structure forms a double leak-proof mechanism. Even if the first leak-proof structure leaks a small amount, it can be intercepted by the second leak-proof structure, further improving the leak-proof performance of the disinfection device.

[0022] 2. The disinfection device proposed in this invention has a first ventilation opening at the top of the protective wall, which means that the water leaking from the first waterproof structure must be higher than the protective wall before entering the first ventilation opening. The vertical height of the protective wall constitutes the interception height of the second waterproof structure, forming a second waterproof barrier.

[0023] 3. The disinfection device proposed in this invention includes a third leak-proof structure comprising an adapter and a second sealing element sleeved outside the adapter. The adapter achieves dynamic sealing between itself and the installation cavity through the second sealing element to open and close the air passage. At the same time, the third leak-proof structure, the first leak-proof structure, and the second leak-proof structure together constitute a multi-layer leak-proof protection system.

[0024] 4. The disinfection device proposed in this invention has the drying module installed and disassembled in opposite directions, namely a first direction and a second direction. This allows the airflow path to be automatically opened when the user performs a tightening operation and to be automatically cut off when the user performs a loosening operation. This simplifies the product structure, reduces the failure rate, avoids the risk of water spillage due to forgetting to close the airflow path when disassembling the module for cleaning, and improves the safety of the device during use.

[0025] 5. The disinfection device proposed in this invention has a distance between the orifice of the connecting port and the inner wall of the second cavity that is smaller than the radius of the float. This limits the horizontal displacement range of the float and prevents the float from deviating too much from the connecting port under the impact of water flow. This ensures that the central axis of the float always tends to be aligned or nearly aligned with the central axis of the connecting port, preventing the float from getting stuck outside the connecting port during its ascent and failing to form a sealing fit with the first sealing element. It also prevents the float from failing to fall back down due to being stuck when the water level drops.

[0026] 6. The disinfection device proposed in this invention has a buffer pad at the bottom of the disinfection chamber to absorb the impact energy when items are placed in, thereby reducing the impact noise generated during operation and improving the user experience; at the same time, since direct rigid contact between the items and the hard bottom of the disinfection chamber is avoided, the blade edge of the knife and the bottom surface of the cutting board are protected from wear or cracking caused by hard impact, thus extending the service life of the appliance.

[0027] 7. The disinfection device proposed in this invention has a cover with several placement openings on the top of the main body, which allows users to store and retrieve items without frequently opening and closing the cover, improving operational convenience and effectively preventing the risk of foreign objects falling.

Detailed Implementation

[0044] The following is combined Figures 1 to 14 The present invention will be described in detail below.

[0045] This embodiment provides a disinfection device, including a main body and a drying module 40. The main body is provided with a disinfection chamber 101 and an air duct 30, an exhaust port and a drain port 102 connected to the disinfection chamber 101. The air outlet of the drying module 40 is connected to the air duct 30.

[0046] The ventilation duct 30 is provided with a first water-proof structure, which includes a floating element 501 and a first sealing element 502. The floating element 501 rises or falls with the water level in the disinfection chamber 101 to seal or detach from the first sealing element 502, thereby closing or opening the ventilation duct 30.

[0047] The air duct 30 is also equipped with a second water-proof structure, which is located between the drying module 40 and the first water-proof structure, and is used to intercept water that leaks through the first water-proof structure.

[0048] The main body has an internal sterilization chamber 101 for accommodating items to be processed (such as knives, cutting boards, etc.), an exhaust vent for expelling hot air from the sterilization chamber 101, and a drain outlet 102 connected to an external drainage pipe. When drying is required, airflow enters the sterilization chamber 101 through the air duct 30 and exits through the exhaust vent; when cleaning or drainage is required, wastewater is discharged through the drain outlet 102.

[0049] The drying module 40 generates hot air to dry the items inside the sterilization chamber 101. The drying module 40 includes a fan 402, a filter 401 located at the air inlet of the fan 402, and a heating element 403 located at the air outlet of the fan 402. The filter 401 filters impurities from the air, preventing them from entering the fan 402 and the heating element 403 and causing dust accumulation or blockage. The heating element 403 is preferably a PTC ceramic heating element, which heats up rapidly, has high thermal efficiency, and possesses automatic temperature control characteristics, effectively ensuring the stability and safety of the drying process.

[0050] The airflow path 30 is a channel structure used to guide airflow from the drying module 40 to the disinfection chamber 101. One end of the airflow path 30 is connected to the disinfection chamber 101, allowing the airflow to act on the items inside the chamber, and the other end is connected to the air outlet of the drying module 40. The function of the airflow path 30 is to construct an airflow transmission channel, and at the same time, it serves as the mounting carrier for the first and second leak-proof structures, ensuring that the leak-proof function can be effective within the airflow path.

[0051] The first leak-proof structure utilizes buoyancy to respond to changes in water level, thereby automatically opening and closing the air passage 30. As the first leak-proof barrier to prevent backflow of water, when the water level is below a threshold, the floating component 501 is in a low position, and the air passage 30 is open; when the water level rises to the threshold, the floating component 501 is driven to rise by buoyancy and fits against the first sealing component 502, blocking the air passage 30 and cutting off the path of water flow to the drying module 40.

[0052] The first leak-proof structure includes a floating element 501 and a first sealing element 502. The floating element 501 is an object with a density less than water that can move with the rise and fall of the liquid level. The shape of the floating element 501 can be a sphere, cylinder, cube, or irregular float, and its material can be solid plastic, hollow metal sphere, or foam material, as long as it can generate sufficient buoyancy in water. The first sealing element 502 is a sealing element fixed within the air passage 30, used to cooperate with the floating element 501 to form a sealed interface. The material of the first sealing element 502 can be rubber, silicone, polyurethane, or other elastomers. The function of the first sealing element 502 is to provide a sealing contact surface. When the floating element 501 abuts against the first sealing element 502, a sealed fit is formed between the two, thereby blocking the passage of fluid.

[0053] The second leak-proof structure is a passive interception component located between the drying module 40 and the first leak-proof structure. Its function is to provide a second leak-proof barrier when the first leak-proof structure fails to completely seal (due to foreign object obstruction, wear, or excessive instantaneous water pressure causing minor leakage). The second leak-proof structure is located in the path of water intrusion into the drying module 40. Even if a small amount of water leaks from the first leak-proof structure, it will be intercepted by the second leak-proof structure, ensuring the electrical safety of the drying module 40.

[0054] When the user flushes the disinfection chamber 101 or the water level in the chamber rises to the first water level line due to blockage of the drain outlet 102 (e.g.) Figure 9 As shown, water enters the air passage 30, and the floating component 501 begins to rise due to the buoyancy of the water. As the water level continues to rise, the floating component 501 gradually approaches and eventually comes into contact with the first sealing component 502, forming a seal that closes the air passage 30 and prevents the water level from spreading further along the air passage 30 towards the drying module 40. During this process, if a very small amount of water still seeps out through the gaps in the first leak-proof structure, this water will encounter the second leak-proof structure on its way to the drying module 40. The seeping water will be intercepted by the second leak-proof structure and will not be able to contact the drying module 40. When the water level drops, the floating component 501 loses sufficient buoyancy support and falls back to its original position under the action of gravity, reopening the air passage 30 and restoring the drying function.

[0055] In this embodiment, the floating component 501 and the first sealing component 502 are integrated inside the air passage 30. The buoyancy of the water itself is used as the driving force, and the air passage 30 can be automatically shut off when the risk of water ingress occurs without the need for external power control, so as to prevent water from flowing into the drying module 40 due to drainage failure. At the same time, since a second leak-proof structure is added between the drying module 40 and the first leak-proof structure, a double leak-proof mechanism is formed. Even if the first leak-proof structure leaks a little, it can be intercepted by the second leak-proof structure, which further improves the leak-proof performance of the disinfection device.

[0056] like Figure 3 and Figure 11 As shown, the main body includes a box 10 and an air duct component 20. The box 10 is provided with a disinfection chamber 101 and a drain outlet 102. The space enclosed by the box 10 and the air duct component 20 is formed by their interconnection to form an air passage 30. The side wall of the air duct component 20 is provided with a protective wall 201 that is recessed inward. The top of the protective wall 201 is provided with a first ventilation opening 202. The drying module 40 is connected to the air passage 30 through the first ventilation opening 202. The protective wall 201 forms a second leak-proof structure.

[0057] The box body 10 and the air duct component 20 are connected to each other by means of snap-fit, screw-fit, adhesive or welding, and the internal cavity formed by the two together after connection is the air duct 30.

[0058] The drain outlet 102 is connected to a drain connector assembly 80, which includes an odor-proof drain 801 and a housing 802. The odor-proof drain 801 is located inside the housing 802, which is connected to the drain outlet 102, thus pressing the odor-proof drain 801 tightly against the drain outlet 102. The internal channel of the housing 802 is connected to the drain pipe. The odor-proof drain 801 opens unidirectionally along the drainage direction of the disinfection chamber 101 to prevent odors from flowing back into the drain pipe.

[0059] The top of the protective wall 201 is provided with a first vent 202, which means that the water leaking from the first leak-proof structure must be higher than the protective wall 201 before entering the first vent 202. Therefore, the vertical height of the protective wall 201 constitutes the interception height of the second leak-proof structure, forming a second leak-proof barrier.

[0060] like Figure 12 and Figure 13 As shown, the disinfection device also includes a third leak-proof structure, which includes a connector 601 and a second sealing member 602 sleeved outside the connector 601. The connector 601 is rotatably installed in the installation cavity enclosed by the protective wall 201, and the connector 601 is movably sealed to the inner wall of the installation cavity by the second sealing member 602.

[0061] The adapter 601 is provided with a flow cavity 6011 and a second vent 6012 connected to the flow cavity 6011. The air outlet of the drying module 40 is connected to the flow cavity 6011. The drying module 40 is connected to the adapter 601. By rotating the drying module 40, the first vent 202 and the second vent 6012 can be connected or disconnected.

[0062] The adapter 601 is rotatably installed in the mounting cavity, and the outer wall of the adapter 601 and the inner wall of the mounting cavity form a relative rotational relationship. The second seal 602 is located between the adapter 601 and the inner wall of the mounting cavity. Its function is to fill the assembly gap between the two, so that a dynamic seal is formed between them, preventing water from flowing into the external environment through the gap between the adapter 601 and the mounting cavity.

[0063] The position of the second vent 6012 changes with the rotation of the adapter 601. When the drying module 40 is rotated, the adapter 601 rotates, causing the second vent 6012 to overlap or misalign with the first vent 202. If they overlap, the air passage 30 opens, and hot air can enter the disinfection chamber 101. Figure 3 As shown; if the two are misaligned, air duct 30 will be closed, as... Figure 8 As shown. The shape and number of the second vent 6012 can be set according to the actual ventilation area requirements, for example, it can be a circular hole, a long groove or multiple evenly distributed small holes.

[0064] The transmission connection between the drying module 40 and the adapter 601 refers to the mechanical connection method by which the rotational motion of the drying module 40 is transmitted to the adapter 601, including but not limited to snap-fit ​​and spline engagement. Specifically, for example... Figure 12 As shown, the outer shell of the drying module 40 is provided with driving teeth, and the adapter 601 is provided with corresponding driven teeth 6013. The driving teeth and driven teeth 6013 mesh with each other, thereby realizing the synchronous driving of the adapter 601 to rotate when the drying module 40 rotates.

[0065] In use, when the first vent 202 and the second vent 6012 are staggered, the drying module 40 and the air duct 30 are completely disconnected. Even if the water level in the disinfection chamber 101 exceeds the height corresponding to the first vent 202, for example, if the water level rises to such a height... Figure 10 As shown by the second water level line, water cannot flow into the flow cavity 6011 through the first vent 202, thus preventing water from entering the drying module 40. Therefore, the third leak-proof structure, together with the first and second leak-proof structures, constitutes a multi-layer leak-proof protection system. The first leak-proof structure relies on the buoyancy of the water level to form an initial barrier, the second leak-proof structure extends the water flow path through the vertical height of the protective wall 201, and the third leak-proof structure achieves the opening and closing of the air passage 30 through dynamic sealing.

[0066] like Figure 8 As shown, the outer wall of the adapter 601 is provided with a first positioning part 701, which is located on the rotation axis of the adapter 601. The inner wall of the mounting cavity facing the first positioning part 701 is provided with a second positioning part 702. The second positioning part 702 cooperates with the recess of the first positioning part 701 to limit the radial displacement of the adapter 601. Specifically, the first positioning part 701 is a convex part and the second positioning part 702 is a concave part. The two cooperate to achieve radial positioning of the adapter 601 in the mounting cavity, ensuring axial stability and no offset when the adapter 601 rotates, thereby ensuring the control of the relative position of the first vent 202 and the second vent 6012.

[0067] When the drying module 40 is rotated and connected to the air duct component 20 in the first direction, the first vent 202 and the second vent 6012 are connected to each other; when the drying module 40 is rotated and disconnected from the air duct component 20 in the second direction, the first vent 202 and the second vent 6012 are disconnected from each other, wherein the first direction and the second direction are opposite to each other.

[0068] like Figure 12As shown, the air duct component 20 has a first snap-fit ​​portion 90, and the drying module 40 has a second snap-fit ​​portion inside the air outlet. The first snap-fit ​​portion 90 and the second snap-fit ​​portion are rotated to achieve the assembly and disassembly of the drying module 40 and the air duct component 20. The first snap-fit ​​portion 90 is an annular flange, and the second snap-fit ​​portion is a matching annular groove. The drying module 40 can be rotated in a first direction or a second direction to make the annular flange engage or disengage from the annular groove, thus completing the assembly or disassembly.

[0069] When the drying module 40 is rotatably connected to the air duct component 20 in the first direction, the drying module 40 drives the adapter 601 to rotate within the mounting cavity, causing the second vent 6012 to gradually move until it coincides with the position of the first vent 202. At this time, the first vent 202 and the second vent 6012 are connected, and the airflow generated by the drying module 40 can enter the air passage 30 through the second vent 6012 and the first vent 202, such as... Figure 3 As shown. At the same time, the drying module 40 and the air duct component 20 are assembled, that is, the annular flange is fully embedded in the annular groove to prevent the drying module 40 from detaching from the box body 10.

[0070] When the drying module 40 rotates in the second direction and disengages from the air duct component 20, the drying module 40 drives the adapter 601 to rotate within the mounting cavity, causing the second vent 6012 to deviate from the position of the first vent 202 until the two are completely misaligned. Figure 8 As shown. At the same time, the drying module 40 and the air duct component 20 are disassembled, that is, the annular flange is disengaged from the annular groove.

[0071] When the drying function needs to be activated, the operator aligns the drying module 40 with the installation position of the air duct component 20 and rotates it in the first direction. As the rotation angle increases, the drive unit inside the drying module 40 drives the adapter 601 to rotate until the second vent 6012 on the adapter 601 is completely aligned with the first vent 202 on the air duct component 20. At this time, the air passage 30 is opened (e.g., Figure 3 (As shown). Conversely, when it is necessary to disassemble the drying module 40 to clean the disinfection chamber 101, rotate the drying module 40 in the second direction to drive the adapter 601 to rotate, so that the second vent 6012 is misaligned with the first vent 202 (as shown). Figure 8 As shown), the air path 30 is pre-cut off before or at the same time as the drying module 40 is completely removed, ensuring that the air path 30 is only opened when the drying module 40 is correctly installed, and the air path 30 is immediately closed during the process of rotating the module out.

[0072] In this embodiment, the installation and disassembly of the drying module 40 are directly converted into the opening and closing of the air duct 30. Specifically, since the first direction and the second direction are opposite to each other, the air duct 30 is automatically opened when the user performs the operation of tightening the drying module 40, and the air duct 30 is automatically cut off when the user performs the operation of loosening the drying module 40. This avoids the risk of water overflow caused by forgetting to close the air duct 30 when disassembling the module for cleaning, and improves the safety of the device during use.

[0073] like Figure 8 As shown, the air passage 30 is provided with a partition 100 that divides the air passage 30 into a first cavity 301 and a second cavity 302. The partition 100 is provided with a connecting port 1001 that connects the first cavity 301 and the second cavity 302. The side wall of the first cavity 301 is provided with a protective wall 201. The second cavity 302 is provided with a floating member 501 and is connected to the disinfection chamber 101. The connecting port 1001 is provided with a first sealing member 502.

[0074] The separator 100 divides the air passage 30 into a first cavity 301 and a second cavity 302. The first cavity 301 is located above the second cavity 302. The function of the first cavity 301 is to provide a space for the protective wall 201 and to extend the path of water flow to the first vent 202. The second cavity 302 provides a space for the floating component 501 to move and a water level sensing area. The separator 100 can be connected to other walls of the air passage 30 (such as the box 10 or the air duct component 20) by means of integral molding, welding, snap-fit, etc., to ensure that there are no other unintended channels between the first cavity 301 and the second cavity 302 except for the connecting port 1001.

[0075] In this embodiment, the duct component 20 is provided with a mounting plate, which has mounting holes. The outer wall of the partition 100 is sealed to the mounting plate. The duct component 20 is also provided with a pressure plate 110, which has a through hole communicating with the communication port 1001. One end of the pressure plate 110 is connected to the duct component 20. When the duct component 20 is connected to the box body 10, the other end of the pressure plate 110 is connected to the box body 10. Thus, the pressure plate 110 presses the partition 100 tightly against the mounting plate, ensuring that the partition 100 is stably fixed in the air passage 30. This prevents the partition 100 from detaching from the mounting hole when the floating component 501 rises and abuts against the first sealing component 502, thereby ensuring the sealing stability between the floating component 501 and the first sealing component 502.

[0076] like Figure 8 As shown, a receiving space 120 is also provided between the protective wall 201 and the pressure plate 110 to expand the volume of the first cavity 301 to accommodate more water, thereby slowing down the rate of water level rise and reducing the possibility that the water level will exceed the horizontal height corresponding to the first ventilation opening 202.

[0077] like Figure 5and Figure 8 As shown, the floating component 501 is a float. The radial dimension of the float is greater than the radial dimension of the connecting port 1001, and the distance between the opening of the connecting port 1001 and the inner wall of the second cavity 302 is less than the radius of the float.

[0078] The radial dimension of the float is set to be larger than that of the connecting port 1001 to ensure that when the float rises, its surface can completely fit the first seal 502, thus preventing the float from entering the first cavity 301 through the connecting port 1001 during the rising process due to its small radial dimension, which would cause the first leak-proof structure to fail.

[0079] The distance between the opening of the connecting port 1001 and the inner wall of the second cavity 302 (including such as Figure 6 and Figure 9 The dimensions A, B, and C shown are smaller than the radius R of the float, i.e., R < A, R < B, and R < C. This limits the range of the float's horizontal displacement, preventing the float from deviating too much from the connection port 1001 under the impact of water flow. This ensures that the central axis of the float always tends to be aligned or nearly aligned with the central axis of the connection port 1001, preventing the float from getting stuck outside the connection port 1001 during its ascent and failing to form a sealing fit with the first seal 502, and preventing the float from failing to fall back down due to being stuck when the water level drops.

[0080] If the distance between the opening of the connecting port 1001 and part of the inner wall of the second cavity 302 is greater than the radius of the float, a limiting structure can be added at the corresponding position on the inner wall of the second cavity 302, such as a protrusion 160 (e.g., Figure 8 As shown), limiting structures such as rubber strips are used to reduce the distance between the orifice and the inner wall of the second cavity 302.

[0081] To prevent the float from entering the disinfection chamber 101 when the water level drops, causing the first leak-proof structure to fail, the maximum radial dimension of the flow hole of the box 10 connected to the second chamber 302 is smaller than the radial dimension of the float. This ensures that the float is always constrained within the second chamber 302 during the water level drop, and ensures that the first leak-proof structure can operate stably.

[0082] like Figure 2As shown, a buffer pad 130 is provided at the bottom of the disinfection chamber 101. The buffer pad 130 is an elastic component set on the inner surface of the bottom of the disinfection chamber 101. Its material can be rubber, silicone, polyurethane foam, or other flexible materials with shock absorption and energy absorption properties. The buffer pad 130 can cover the entire bottom area of ​​the disinfection chamber 101, or it can be a strip structure distributed along the bottom edge, or a multi-protrusion structure 160 distributed in a dot matrix. The function of the buffer pad 130 is to act as an intermediate medium between the item, cutting board, etc., and the rigid inner wall of the disinfection chamber 101 when they are placed in it. It absorbs the impact energy generated during the falling or placement of the item through its own elastic deformation, thereby reducing the impact force.

[0083] Because a buffer pad 130 is installed at the bottom of the sterilization chamber 101, it absorbs the impact energy when items are placed in, thereby reducing the impact noise generated during operation and improving the user experience. At the same time, because direct rigid contact between items and the hard bottom of the sterilization chamber 101 is avoided, the blade edge and the bottom surface of the cutting board are protected from wear or cracking caused by hard impacts, thus extending the service life of the utensils.

[0084] like Figure 11 As shown, the top of the main body is provided with a cover plate 140, and the cover plate 140 has several placement openings 1401 that connect to the disinfection chamber 101. The placement openings 1401 constitute an exhaust port. The function of the cover plate 140 is to maintain a relatively sealed environment inside the disinfection chamber 101 to prevent hot air from flowing out of the disinfection chamber 101 too quickly during the drying process and to prevent foreign objects from entering.

[0085] The placement opening 1401 is an opening structure located on the cover plate 140, allowing items to be disinfected (such as knives, cutting boards, etc.) to pass through and enter the disinfection chamber 101. The number, shape, and size of the placement openings 1401 can be set according to actual disinfection needs and the specifications of the items to be treated. For example, it can be a long, narrow slit to accommodate knife insertion, or it can be rectangular to accommodate cutting boards. The placement opening 1401 communicates with the disinfection chamber 101, and its function is to provide a passage for kitchen utensils and other items, allowing users to place or remove items without opening the cover plate 140. At the same time, the placement opening 1401 allows airflow out of the disinfection chamber 101, so the placement opening 1401 can also serve as an exhaust vent to expel airflow from the disinfection chamber 101 and promote air circulation within the disinfection chamber 101. As can be seen, this embodiment provides a cover plate 140 with several placement openings 1401 on the top of the main body, so that users can store and retrieve items without frequently opening and closing the cover plate 140, which improves the convenience of operation and effectively prevents the risk of foreign objects falling.

[0086] When a user needs to perform disinfection, the items to be disinfected are inserted into the disinfection chamber 101 through the placement port 1401. At this time, the cover plate 140 covers the top of the main body, isolating the disinfection chamber 101 from the external environment except for the area of ​​the placement port 1401. During the drying or disinfection process, the airflow or disinfection medium circulates within the disinfection chamber 101, and excess airflow is discharged from the disinfection chamber 101 through the placement port 1401.

[0087] In kitchen washing and food processing scenarios, the sink is the core equipment used for washing tableware, cookware, and ingredients. Traditional sink systems typically only have basic storage and drainage functions, lacking effective in-situ disinfection and drying methods for cookware such as cutting boards and knives placed in or around the sink that are prone to bacterial growth. Users often need to move the cookware to a separate disinfection cabinet for processing, or let it air dry after use. This is not only cumbersome and takes up extra kitchen space, but air drying is also inefficient and can easily lead to bacterial growth due to the damp environment, posing a hygiene risk.

[0088] To overcome the above problems, this embodiment provides a sink device that integrates a disinfection device with multiple leak-proof protection functions into the sink structure, thereby achieving integrated washing, disinfection, and drying. This solution utilizes the structural characteristics of the sink itself to provide an installation foundation for the disinfection device, thus solving the problems of traditional sinks having limited functionality and the inconvenience of installing independent disinfection equipment.

[0089] like Figure 14 As shown, this embodiment also provides a water tank device, including a tank body 150, the tank body 150 having a receiving groove 1501 and an overlapping area 1502 located on the outer edge of the receiving groove 1501, and also including any of the above embodiments of disinfection device, the overlapping area 1502 having a clearance opening for receiving the main body.

[0090] The tank body 150 refers to the structural component that forms the overall frame of the sink. The receiving tank 1501 is a recessed area used to hold items to be washed and washing water, and its bottom is connected to a drain pipe to discharge wastewater. The overlapping area 1502 refers to the extended platform or flange structure located on the outer edge of the receiving tank 1501. The clearance opening refers to a through hole made in the overlapping area 1502, the shape of which matches the body of the disinfection device. Its purpose is to accommodate the body of the disinfection device, so that after installation, the body of the disinfection device can at least partially pass through the overlapping area 1502, so that the placement opening 1401 faces upward, which is convenient for placing cutting boards, knives and other kitchen utensils.

[0091] The disinfection device is located in the cabinet space below the sink 150, making use of the unused cabinet space below the sink 150 to avoid occupying additional kitchen countertop or other cabinet storage space. The main body is connected to the overlapping area 1502 through the clearance opening, so that the disinfection device is connected to the sink 150.

[0092] When in use, insert a clean cutting board or knife into the sterilization chamber 101 through the placement port 1401, start the drying module 40, and hot air is evenly introduced into the sterilization chamber 101 through the air path 30 to dry the cutting board or knife. The hot air forms a circulating airflow in the sterilization chamber 101, continuously removing moisture from the surface of the kitchen utensils until drying is complete.

[0093] After multiple drying processes, residues may remain in the disinfection chamber 101, affecting subsequent disinfection effectiveness. At this point, the user rotates the drying module 40 in the second direction to detach it from the air duct component 20. During this rotation, the drying module 40 drives the adapter 601 to rotate, causing the first vent 202 and the second vent 6012 to be misaligned, thereby closing the air path 30 and preventing water from flowing out of the disinfection device through the first vent 202 and the second vent 6012. Then, the user pulls out the faucet assembly installed in the tank 150 and aligns it with the placement port 1401, using water flow to clean the disinfection chamber 101 and remove any remaining residue.

[0094] A large amount of water flows into the disinfection chamber 101 instantly, and when the water level rises to the first water level line (such as...). Figure 9 As shown), the floating component 501 rises under buoyancy and cooperates with the first sealing component 502, automatically sealing the air passage 30 and preventing water from flowing into the first cavity 301. At the same time, the second leak-proof structure intercepts a small amount of water droplets that may leak out. When the water level in the disinfection cavity 101 continues to rise to the second water level line (as shown), Figure 10 As shown in the figure, the second water level is higher than the horizontal height corresponding to the first vent 202. Even if the water level in the first cavity 301 rises to the second water level, the water cannot flow out because the first vent 202 is closed, thus preventing the cabinet from being soaked by water.

[0095] After the cleaning is completed and the water intake is stopped, the water in the disinfection chamber 101 is discharged through the drain outlet 102. The floating part 501 is disengaged from the first sealing part 502 as the water level drops, so that the water in the first chamber 301 is discharged into the disinfection chamber 101 through the second chamber 302 until all the water in the disinfection chamber 101 is discharged. The drying module 40 is rotated and snapped onto the air duct part 20 in the first direction, thereby driving the adapter 601 to rotate, so that the first vent 202 and the second vent 6012 are realigned, the air duct 30 is restored to unobstructed, and the next round of disinfection and drying cycle can begin.

[0096] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
