Description

Technical Field

[0001] This invention relates to the field of household goods technology, and in particular to a chopstick sterilizer. Background Technology

[0002] A chopstick sterilizer is a small kitchen appliance that integrates sterilization, drying, and storage functions. It uses ultraviolet light combined with high-temperature hot air drying to hygienically treat tableware such as knives, chopsticks, and spoons to prevent bacterial growth and cross-contamination.

[0003] Existing chopstick sterilizers typically feature a fixed or detachable chopstick holder within the sterilization chamber, storing the tableware vertically. For example, the chopstick sterilizer disclosed in patent CN218685350U employs this structure. This design has significant drawbacks: the limited distance between the chopstick holder and the top surface of the sterilization chamber makes it inconvenient to place and retrieve tableware; for shorter tableware such as small knives and forks, fruit forks, spoons, or children's chopsticks, their length is less than the height of the chopstick holder, making them difficult to remove after placement. Even with a detachable chopstick holder, additional disassembly and assembly are required, making the process cumbersome and resulting in a poor overall user experience, urgently requiring optimization. Summary of the Invention

[0004] To overcome the problems existing in related technologies, the present invention provides a chopstick sterilizer.

[0005] The purpose of this invention is to provide a chopstick sterilizer: It includes a box body with a disinfection chamber, and a door cover installed at the opening end of the disinfection chamber for opening and closing the disinfection chamber; The bottom end of the door cover is rotatably connected to the box body, and a bracket is provided on the back of the door cover, the bracket including two connecting seats spaced apart; A first disinfection basket is provided between the two connecting seats, and the two ends of the first disinfection basket are respectively connected to the corresponding connecting seats. The door cover has an open state and a closed state; When closed, the door covers the disinfection chamber, and the first disinfection basket is stored inside the disinfection chamber; When in the open position, the door opens the disinfection chamber and brings the first disinfection basket out of the disinfection chamber.

[0006] In a preferred embodiment of the present invention, the bracket is provided with an arc-shaped sliding groove, and a first slider is provided in the arc-shaped sliding groove. The first slider is disposed on the end face of the short side of the first disinfection basket. When in the closed state, the first slider abuts against one end of the arc-shaped groove; When in the open state, the first slider abuts against the other end of the arc-shaped groove; During the opening and closing of the door, the first disinfection basket moves along the arc-shaped groove under the action of gravity and always remains horizontal.

[0007] In a preferred embodiment of the present invention, a second disinfection basket is further included, which is located above the first disinfection basket; The second disinfection basket is slidably installed inside the disinfection chamber and can move toward the opening end of the disinfection chamber.

[0008] In a preferred embodiment of the present invention, to further improve convenience, the movement method of the second disinfection basket can be further optimized. Specifically, a support member is provided inside the disinfection chamber, and the support member includes two guide rails correspondingly disposed on the side walls of the disinfection chamber; The guide rail is inclined, with the side of the guide rail away from the opening of the disinfection chamber being the high point and the side of the guide rail close to the opening of the disinfection chamber being the low point. The two ends of the second disinfection basket are respectively supported on the corresponding guide rails and slide in cooperation with the guide rails; When closed, the door cover abuts against the second disinfection basket, limiting its movement. When in the open state, the door cover separates from the second disinfection basket, and the second disinfection basket moves towards the opening of the disinfection chamber along the guide rail under the influence of gravity. When the door cover is open, the second disinfection basket automatically moves outward under the influence of gravity; when the door cover is closed, the door cover pushes the second disinfection basket inward. This design allows the second disinfection basket to slide along the guide rail under gravity when the cover is opened, realizing the function of automatically moving the second disinfection basket outward during the opening operation; when the cover is closed, the door cover pushes the second disinfection basket to move in the opposite direction, realizing the function of the second disinfection basket retracting in conjunction with the opening operation, making the operation more convenient for users.

[0009] In a preferred embodiment of the present invention, a second slider is provided on the guide rail, and the second slider is disposed on the end face of the short side of the second disinfection basket. When in the open position, the second slider is located at the lowest point of the guide rail.

[0010] In a preferred embodiment of the present invention, a limiting part is provided on the bottom surface and / or top surface of the first slider. During the movement of the first disinfection basket along the arc groove, the limiting part remains in contact with the inner wall of the arc groove, and the first disinfection basket cannot rotate around the central axis of the first slider. The bottom and / or top surfaces of the second slider are provided with limiting parts. During the movement of the second disinfection basket along the guide rail, the limiting parts remain in contact with the inner wall of the guide rail, and the second disinfection basket cannot rotate around the central axis of the second slider. Preferably, the limiting part is designed as a plane.

[0011] In a preferred embodiment of the present invention, the high point of the guide rail is provided with a clearance opening for the second slider to move out, so as to allow the second disinfection basket to be disassembled and assembled; when the door is closed, the second slider is located between the high point and the low point. Alternatively, the top surface of the guide rail is provided with a clearance opening for the second slider to move out, so as to allow the disinfection basket to be disassembled and assembled. When the door is closed, the slider is located at the highest point of the guide rail.

[0012] In a preferred embodiment of the present invention, through holes are symmetrically arranged on both sides of the bottom of the disinfection chamber, and a connecting rod is inserted through the through hole. The connecting rod is used to improve the stability of opening the lid and avoid the lack of restraint when the lid is rotated. The connecting rod is slidably engaged with the through hole. One end of the connecting rod extends out of the through hole and is hinged to the connecting seat on the same side. The other end is provided with a limit stop. The sliding engagement between the connecting rod and the through hole can generate damping force, reduce the falling speed of the door cover, and prevent the door cover from falling too fast and causing impact damage to the rotating parts of the door cover and the box body. The limiting block is used to prevent the connecting rod from coming off. When the door cover is in the open state, the limiting block abuts against the box body.

[0013] In a preferred embodiment of the present invention, an outer flange is provided on the outer periphery of the opening end of the disinfection chamber, and the through hole is formed on the outer flange. Specifically, the through hole is located at the junction of the outer flange and the inner wall of the disinfection chamber, and the through hole is connected to the disinfection chamber. This design allows the through hole to serve as an exhaust channel, discharging the hot airflow blown into the disinfection chamber.

[0014] In a preferred embodiment of the present invention, both the first and second sterilization baskets are elongated, allowing tableware to be laid flat and stored within them. This facilitates the removal of small, elongated tableware such as knives, forks, fruit forks, spoons, or children's chopsticks, and better accommodates tableware of different lengths.

[0015] In a preferred embodiment of the present invention, a plurality of drainage vents are evenly provided on the first and second disinfection baskets. The drainage vents not only allow water to drain from the tableware, but also ensure that the hot air and disinfection light inside the disinfection chamber act more evenly on the surface of the tableware, thus guaranteeing the disinfection and drying effect.

[0016] In a preferred embodiment of the present invention, the box body includes an outer shell and an inner shell, both of which are open at the front end. A panel is provided on the outer periphery of the front end of the inner shell, and the panel covers the open end of the outer shell. The inner wall of the inner shell forms a sterilization chamber for accommodating tableware, and the inner wall of the outer shell, the outer wall of the inner shell, and the panel together form a cavity for airflow circulation. The door cover is mounted on the panel; The inner shell has an air inlet and an air outlet that are respectively connected to the cavity. The air inlet is used to guide the airflow from the cavity into the disinfection cavity, and the air outlet is used to discharge the airflow from the disinfection cavity back into the cavity, thereby forming a hot air circulation. The outer shell has a fresh air inlet that connects the outside to the cavity, which is used to replenish the cavity with fresh air; A drying component is installed at the air inlet. The drying component can draw airflow from the cavity and heat it, and then send the hot airflow into the disinfection cavity to achieve hot air circulation drying.

[0017] This design achieves the recycling and reuse of hot air through a dual-cavity design. The high-temperature hot air recovered by the cavity can be used to preheat newly introduced fresh air, which greatly reduces the power consumption of the heating element. At the same time, the recovered hot air itself has drying capabilities and is still higher than the ambient temperature after mixing with fresh air, which can more efficiently evaporate moisture on the surface and in the crevices of tableware.

[0018] In a preferred embodiment of the present invention, the air inlet is located in the middle of the top surface of the inner shell, and the drying assembly includes an air duct body, a fan, and an electric heating assembly; preferably, the fan is a centrifugal fan, and the electric heating assembly is a PTC heating element. The air duct body has an air inlet on one short side that communicates with the cavity, and the fan is installed at the air inlet to draw airflow from the cavity. The bottom surface of the air duct body is provided with an air outlet, and the air outlet is connected to the air inlet; preferably, the air outlet is embedded in the air inlet. The air duct body is provided with a heating cavity section, an air gathering cavity section and a flow distribution cavity section in sequence along the direction away from the air inlet. The air outlet is located at the bottom of the air gathering cavity section and the flow distribution cavity section. The electric heating component is fixed in the heating cavity section and is used to heat the airflow. The cross-sectional area of ​​the air-gathering cavity gradually decreases along the direction away from the air inlet. The air-gathering cavity is used to converge and accelerate the airflow. The diversion cavity is provided with several air guide plates at intervals along the direction away from the air inlet, and the height of each air guide plate increases sequentially along the direction away from the air inlet. The air guide plates are used to intercept and divert the converged airflow, so that the air outlet is more uniform.

[0019] During use, the airflow entering through the air inlet is heated by the electric heating component in the heating chamber section, and then converges and accelerates in the air gathering chamber section. When passing through the air guide plate, part of the airflow is guided to the air outlet, and the remaining airflow flows to the next air guide plate. This design improves the uniformity of airflow distribution by optimizing the cavity design of the air duct and the progressively increasing height design of the air guide plate, thereby improving drying efficiency and reducing energy consumption.

[0020] In a preferred embodiment of the present invention, the air guide plate is disposed on the inner wall surface of the air duct body on the side opposite to the air outlet, the two sides of the air guide plate are in contact with the inner wall of the air duct body, and an air passage is formed between the air guide plate and the air outlet.

[0021] In a preferred embodiment of the present invention, the air outlet is equipped with an air distribution plate, and the air distribution plate is provided with a plurality of air supply holes evenly distributed thereon.

[0022] In a preferred embodiment of the present invention, the top surface of the air-gathering cavity section is an air-guiding surface, and the air-guiding surface has a first arc surface and a second arc surface along the direction away from the air inlet. The first and second arc surfaces bend in opposite directions, achieving secondary airflow guidance and optimizing the convergence and diffusion effects of the airflow. Preferably, the first arc surface is a convex arc surface, and the second arc surface is a concave arc surface, with the first and second arc surfaces smoothly connected to enhance the airflow convergence capability and lay the foundation for the subsequent interception and diversion of the flow in the diversion cavity.

[0023] In a preferred embodiment of the present invention, the side of the air guide plate facing the air inlet is either a sloping air guide surface with its bottom end inclined away from the air inlet, or a convex air guide arc surface. The side of the air guide plate facing the air inlet is used to smoothly guide the airflow delivered by the air gathering chamber towards the air outlet, and the increasing height design of the air guide plate makes the airflow more evenly distributed.

[0024] In a preferred embodiment of the present invention, an ultraviolet disinfection lamp is installed inside the disinfection chamber to disinfect the tableware inside the chamber with ultraviolet light, which, together with hot air drying, achieves dual hygiene treatment.

[0025] In a preferred embodiment of the present invention, a tool slot is provided on the top of the outer casing, and the tool slot communicates with the cavity. This allows the hot airflow in the cavity to flow over the surface of the tool, achieving simultaneous drying and sterilization of the tool.

[0026] In a preferred embodiment of the present invention, the air outlet is located on the back of the inner housing, the fresh air inlet is located on the top of the back of the outer housing, and an installation space for accommodating the drying assembly is formed between the top surface of the inner housing and the top surface of the outer housing.

[0027] In a preferred embodiment of the present invention, the door cover is rotatably coupled with the panel via a shaft, and the panel is provided with a shaft hole for mounting the shaft. A locking pin is provided on the top of the door cover, and a latch is provided on the panel or inner shell to cooperate with the locking pin, so as to realize the stable closing and convenient opening of the door cover; preferably, the latch is a self-locking rebound device. In the closed state, the pin is inserted and self-locking rebounds to fix the door cover. Alternatively, a magnetic component A is provided at the top of the door cover, and a corresponding magnetic component B is provided on the panel or inner shell. In the closed state, magnetic component A and magnetic component B are magnetically attracted to each other. Alternatively, when closed, the door cover remains in contact with the box body due to the gravity of the first disinfection basket.

[0028] Preferably, in the closed state, the door cover is kept in contact with the box body by the gravity of the first disinfection basket. At the same time, corresponding magnetic components are provided on the top of the door cover and the outer flange of the inner shell to prevent the door cover from being opened accidentally.

[0029] The beneficial effects of this invention are as follows: The device includes a box body with a sterilization chamber, and a door cover installed at the opening of the sterilization chamber for opening and closing. The bottom end of the door cover is rotatably connected to the box body, and a bracket is provided on the back of the door cover. The bracket includes two spaced-apart connecting seats. A first sterilization basket is provided between the two connecting seats, and both ends of the first sterilization basket are connected to the corresponding connecting seats. The door cover has an open state and a closed state. When closed, the door cover covers the sterilization chamber, and the first sterilization basket is stored inside the sterilization chamber. When open, the door cover opens the sterilization chamber and brings the first sterilization basket out of the sterilization chamber. This design allows the first sterilization basket to move out of the sterilization chamber when the door cover is open, improving the convenience of taking out and putting away tableware.

[0040] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Example

[0041] The purpose of Example 1 is to provide a convenient chopstick sterilizer. like Figure 1-6 As shown, this embodiment provides a chopsticks sterilizer: It includes a box body 500 with a disinfection chamber 521, and a door cover 900 installed at the opening end of the disinfection chamber 521 for opening and closing the disinfection chamber 521; The bottom end of the door cover 900 is rotatably connected to the box body 500, and a bracket is provided on the back of the door cover 900. The bracket includes two connecting seats 910 spaced apart. A first disinfection basket 700 is provided between the two connecting seats 910, and the two ends of the first disinfection basket 700 are respectively connected to the corresponding connecting seats 910; the disinfection basket is used to place tableware, which are small, long kitchen utensils such as knives, forks, spoons or chopsticks; The door cover 900 has an open state and a closed state; When closed, the door cover 900 covers the disinfection chamber 521, and the first disinfection basket 700 is stored inside the disinfection chamber 521. When in the open state, the door cover 900 opens the disinfection chamber 521 and brings the first disinfection basket 700 out of the disinfection chamber 521; When the door cover 900 is opened, this design can move the disinfection basket to the outside of the disinfection chamber 521, improving the convenience of taking out and putting away tableware.

[0042] In this embodiment, the bracket is provided with an arc-shaped sliding groove 911, and a first slider 710 is provided in the arc-shaped sliding groove 911. The first slider 710 is provided on the end face of the short side of the first disinfection basket 700; specifically, the first slider 710 is provided in the middle of the end face of the short side of the first disinfection basket 700. When in the closed state, the first slider 710 abuts against one end of the arc-shaped groove 911; When in the open state, the angle between the door cover 900 and the horizontal plane is no greater than 20 degrees, and the first slider 710 abuts against the other end of the arc groove 911; preferably, when in the closed state, the door cover 900 is vertical; when in the open state, the door cover 900 is horizontal. During the opening and closing of the door cover 900, the first disinfection basket 700 moves along the arc-shaped slide groove 911 under the action of gravity and always remains horizontal.

[0043] In this embodiment, a second disinfection basket 800 is also included, which is located above the first disinfection basket 700; The second disinfection basket 800 is slidably installed inside the disinfection chamber 521 and can move toward the opening end of the disinfection chamber 521.

[0044] In this embodiment, to further improve convenience, the movement method of the second disinfection basket 800 can be further optimized. Specifically, a support member is provided inside the disinfection chamber 521, and the support member includes two guide rails 515 correspondingly disposed on the two side walls of the disinfection chamber 521; The guide rail 515 is inclined, with the side of the guide rail 515 away from the opening of the disinfection chamber 521 being the high point 5152 and the side of the guide rail 515 close to the opening of the disinfection chamber 521 being the low point 5151. The second disinfection basket 800 is supported on the corresponding guide rail 515 at both ends and slides with the guide rail 515. When closed, the door cover 900 abuts against the second disinfection basket 800, limiting the second disinfection basket 800; When in the open state, the door cover 900 is separated from the second disinfection basket 800. The second disinfection basket 800 moves along the guide rail 515 towards the opening of the disinfection chamber 521 under the influence of gravity. When the door cover 900 is open, the second disinfection basket 800 automatically moves outward under gravity. When the door cover 900 is closed, the door cover 900 pushes the second disinfection basket 800 inward. This design allows the second disinfection basket 800 to slide along the guide rail 515 under gravity when the cover is opened, achieving the function of automatic outward movement during opening operations. When the cover is closed, the door cover 900 pushes the second disinfection basket 800 to move in the opposite direction, achieving the function of synchronized inward movement of the second disinfection basket 800, making operation more convenient for users.

[0045] In this embodiment, a second slider 810 is provided on the guide rail 515, and the second slider 810 is disposed on the end face of the short side of the second disinfection basket 800; specifically, the second slider 810 is disposed in the middle of the end face of the short side of the second disinfection basket 800. When in the open state, the second slider 810 is located at the low point 5151 of the guide rail 515.

[0046] In this embodiment, a limiting part is provided on the bottom surface and / or top surface of the first slider 710. During the movement of the first disinfection basket 700 along the arc groove 911, the limiting part remains in contact with the inner wall of the arc groove 911, and the first disinfection basket 700 cannot rotate around the central axis of the first slider 710, so as to ensure the smoothness of the sliding of the first disinfection basket 700. The bottom and / or top surfaces of the second slider 810 are provided with limiting parts. During the movement of the second disinfection basket 800 along the guide rail 515, the limiting parts remain in contact with the inner wall of the guide rail 515, and the second disinfection basket 800 cannot rotate around the central axis of the second slider 810, so as to ensure the smoothness of the sliding of the second disinfection basket 800. Preferably, the limiting part is designed as a plane.

[0047] In this embodiment, the high point 5152 of the guide rail 515 is provided with a clearance opening 5153 for the second slider 810 to move out, so as to allow the second disinfection basket 800 to be disassembled and assembled; when the door cover 900 is in the closed state, the second slider 810 is located between the high point 5152 and the low point 5151. Alternatively, the top surface of the guide rail 515 is provided with a clearance opening 5153 for the second slider 810 to move out, so as to allow the disinfection basket to be disassembled and assembled. When the door cover 900 is in the closed state, the slider is located at the high point 5152 of the guide rail 515.

[0048] In this embodiment, through holes 514 are symmetrically arranged on both sides of the bottom of the disinfection chamber 521. A connecting rod 920 passes through the through hole 514. The connecting rod 920 is used to improve the stability of opening the cover and avoid the lack of restraint when the cover 900 rotates. The connecting rod 920 is slidably engaged with the through hole 514. One end of the connecting rod extends out of the through hole 514 and is hinged to the connecting seat 910 on the same side. The other end is provided with a limit stop 921. The sliding engagement between the connecting rod 920 and the through hole 514 can generate damping force, which slows down the falling speed of the door cover 900 and prevents the door cover 900 from falling too fast and causing impact damage to the rotating parts of the door cover 900 and the box body 500. The limiting block 921 is used to prevent the connecting rod 920 from coming out. When the door cover 900 is in the open state, the limiting block 921 abuts against the box body 500.

[0049] In this embodiment, an outer flange is provided on the outer periphery of the opening end of the disinfection chamber 521, and the through hole 514 is formed on the outer flange. Specifically, the through hole 514 is located at the junction of the outer flange and the inner wall of the disinfection chamber 521, and the through hole 514 is connected to the disinfection chamber 521. This design allows the through hole 514 to serve as an exhaust channel, discharging the hot airflow blown into the disinfection chamber 521.

[0050] In this embodiment, both the first sterilization basket 700 and the second sterilization basket 800 are elongated, allowing tableware to be laid flat and stored in the baskets. This facilitates the removal of small, elongated tableware such as small knives, forks, fruit forks, spoons, or children's chopsticks, and better accommodates tableware of different lengths.

[0051] In this embodiment, the first disinfection basket 700 and the second disinfection basket 800 are evenly provided with a plurality of drainage vents. The drainage vents not only allow water to drain from the tableware, but also allow the hot air and disinfection light inside the disinfection chamber 521 to act more evenly on the surface of the tableware, ensuring the disinfection and drying effect. Example

[0052] In existing chopstick sterilizers, the hot air vent is usually located at the top or bottom of the sterilization chamber 521. The hot air input from the hot air vent is directly discharged to the outside through the sterilization chamber 521 without being recycled, resulting in low drying efficiency. To ensure that the tableware is completely dried, the drying time needs to be extended, which further increases the energy consumption of the equipment.

[0053] Based on the above problems, the purpose of Example 2 is to further design the chopstick sterilizer based on Example 1, so as to improve drying efficiency and reduce energy consumption through hot air circulation.

[0054] like Figure 1-9 As shown, a hot air circulating chopstick sterilizer: The chopstick sterilizer included in Embodiment 1 includes a box body 500 comprising an outer shell 510 and an inner shell 520, both of which are open at the front end. A panel 600 is provided on the outer periphery of the front end of the inner shell 520, and the panel 600 covers and closes the opening end of the outer shell 510. Preferably, the panel 600 is provided with an installation opening, and the inner shell 520 is fitted into the installation opening. The inner shell 520 and the panel 600, and the outer shell 510 and the panel 600 are all assembled in a detachable connection manner. The inner wall of the inner shell 520 forms a sterilization chamber 521 for accommodating tableware, and the inner wall of the outer shell 510, the outer wall of the inner shell 520, and the panel 600 together form a chamber 511 for airflow circulation. The door cover 900 is mounted on the panel 600; The inner shell 520 is provided with an air inlet 523 and an air outlet 522 that are respectively connected to the cavity 511. The air inlet 523 is used to introduce the airflow of the cavity 511 into the disinfection cavity 521, and the air outlet 522 is used to discharge the airflow of the disinfection cavity 521 to the cavity 511, thereby forming a hot air circulation. The outer shell 510 is provided with a fresh air inlet 512 that connects the outside to the cavity 511, for supplying fresh air to the cavity 511; A drying component is installed at the air inlet 523. The drying component can extract the airflow in the cavity 511 and heat it, and then send the hot airflow into the disinfection cavity 521 to achieve hot air circulation drying.

[0055] This design achieves the recycling and reuse of hot air through a dual-cavity design. The high-temperature hot air recovered by cavity 511 can be used to preheat newly introduced fresh air, which greatly reduces the power consumption of the heating element. At the same time, the recovered hot air itself has drying capabilities and is still higher than the ambient temperature after mixing with fresh air, which can more efficiently evaporate moisture on the surface and in the crevices of tableware.

[0056] In this embodiment, the air inlet 523 is located in the middle of the top surface of the inner shell 520, and the drying assembly includes an air duct body 100, a fan 300, and an electric heating assembly 400; preferably, the fan 300 is a centrifugal fan, and the electric heating assembly 400 is a PTC heating element. The air duct body 100 has an air inlet 110 on one short side that communicates with the cavity 511. The fan 300 is installed at the air inlet 110 to draw airflow from the cavity 511. The bottom surface of the air duct body 100 is provided with an air outlet 150, and the air outlet 150 is connected to the air inlet 523; preferably, the air outlet 150 is embedded in the air inlet 523. The air duct body 100 is provided with a heating cavity section 120, an air concentrating cavity section 130 and a flow diversion cavity section 140 in sequence along the direction away from the air inlet 110. The air outlet 150 is located at the bottom of the air concentrating cavity section 130 and the flow diversion cavity section 140. The electric heating component 400 is fixedly installed in the heating cavity section 120 and is used to heat the airflow. The cross-sectional area of ​​the air-gathering cavity section 130 gradually decreases along the direction away from the air inlet 110. The air-gathering cavity section 130 is used to converge and increase the airflow. The diversion cavity section 140 is provided with several air guide plates 141 at intervals along the direction away from the air inlet 110, and the height of each air guide plate 141 increases sequentially along the direction away from the air inlet 110. The air guide plates 141 are used to intercept and divert the converged airflow, so that the air outlet 522 can discharge more evenly.

[0057] In use, the airflow entering through the air inlet 110 is heated by the electric heating component 400 in the heating chamber section 120, and then converges and accelerates in the air concentrating chamber section 130. When passing through the air guide plate 141, part of the airflow is guided to the air outlet 150 by the air guide plate 141, and the remaining airflow flows to the next air guide plate 141. This design improves the uniformity of airflow distribution by optimizing the chamber design of the air duct and the progressively increasing height design of the air guide plate 141, thereby improving drying efficiency and reducing energy consumption.

[0058] In this embodiment, the air guide plate 141 is disposed on the inner wall surface of the air duct body 100 on the side opposite to the air outlet 522. The two sides of the air guide plate 141 are attached to the inner wall of the air duct body 100, and an air passage is formed between the air guide plate 141 and the air outlet 150.

[0059] In this embodiment, an air distribution plate 200 is installed at the air outlet 522, and the air distribution plate 200 has a plurality of air supply holes evenly distributed on it. The air distribution plate 200 is used to perform secondary distribution of the split airflow, further improving the uniformity of the air outlet.

[0060] In this embodiment, the top surface of the air-gathering cavity section 130 is a guide surface, which is used to guide the airflow to smoothly transition to the diversion cavity section 140 and avoid airflow turbulence. The guide surface has a first arc surface 131 and a second arc surface 132 along the direction away from the air inlet 110. The first arc surface 131 and the second arc surface 132 have opposite curvature directions, achieving secondary airflow guidance and optimizing the convergence and diffusion effects of the airflow. Preferably, the first arc surface 131 is a convex arc surface, and the second arc surface 132 is a concave arc surface, with the first arc surface 131 and the second arc surface 132 smoothly connected to enhance the airflow convergence capability and lay the foundation for the subsequent interception and diversion of the flow in the diversion cavity section 140.

[0061] In this embodiment, the side of the air guide plate 141 facing the air inlet 110 is either a sloping air guide surface with its bottom end facing away from the air inlet 110, or a convex air guide arc surface. The side of the air guide plate 141 facing the air inlet 110 is used to smoothly guide the airflow delivered by the air gathering chamber section 130 towards the air outlet 522. The progressively increasing height design of the air guide plate 141 further ensures more even airflow distribution.

[0062] In this embodiment, an ultraviolet disinfection lamp is installed in the disinfection chamber 521 to disinfect the tableware in the disinfection chamber 521 with ultraviolet light, and achieves dual hygiene treatment in combination with hot air drying.

[0063] In this embodiment, a tool slot 513 is provided on the top of the outer shell 510, and the tool slot 513 communicates with the cavity 511. This allows the hot airflow in the cavity 511 to flow over the surface of the tool, achieving simultaneous drying and sterilization of the tool. Of course, for further sterilization of the tool, an ultraviolet sterilization lamp can be installed inside the cavity 511.

[0064] In this embodiment, the air outlet 522 is located on the back of the inner housing 520, and the fresh air inlet 512 is located on the top of the back of the outer housing 510. An installation space for accommodating the drying component is formed between the top surface of the inner housing 520 and the top surface of the outer housing 510, and the installation space is located in the cavity 511. Example
