[0028] See also Figures 1 to 6 The present application provides a disinfection cabinet 100, which includes a disinfection inner container 10 and a heating element 20. The disinfection inner container 10 is provided with a bottom plate 11 and a disinfection chamber 101. Tableware is stored in the disinfection chamber 101. The heating element 20 is provided on the side of the bottom plate 11 facing the disinfection chamber 101. The heating element 20 can emit heat to the disinfection chamber 101 to dry the tableware in the disinfection chamber 101. In the prior art, the heat from the side of the heating element 20 facing the disinfection chamber 101 can directly rise to the tableware for drying. Part of the heat from the side of the heating element 20 facing the bottom plate 11 is reflected into the disinfection chamber 101 through the bottom plate 11, and the other part is emitted outward through the bottom plate 11, resulting in a large heat loss.
[0029] Furthermore, the disinfection cabinet 100 further includes a heat-conducting structure 30, which is located below the heating element 20. The heat-conducting structure 30 can fully absorb the heat of the heating element 20 on the side facing the bottom plate 11. In the prior art, a pull-out basket is usually provided in the disinfection liner 10, and the pull-out basket is used to place tableware. The pull-out basket near the heating element 20 directly receives the heat radiated by the heating element 20. Therefore, after part of the heat of the heating element 20 is absorbed by the heat-conducting structure 30, the temperature of the pull-out basket near the heating element 20 can also be reduced, thereby avoiding the problem of melting of tableware in the pull-out basket due to excessive temperature, and also avoiding excessive temperature of the pull-out basket near the heating element 20 after drying, which may cause burns to the human body, thereby promoting safe use.
[0030] Furthermore, the disinfection cabinet 100 also includes an energy storage structure 40, which includes a first energy storage box 41. The first energy storage box 41 is attached to the heat-conducting structure 30 and is provided with a first energy storage cavity 411. The first energy storage box 41 is located below the bottom plate 11. One end of the heat-conducting structure 30 is close to the heating element 20, and the other end is arranged between the bottom plate 11 and the first energy storage box 41. In this way, when the heating element 20 is turned on, the heat-conducting structure 30 can transfer part of the heat to the bottom plate 11 and continue to dissipate into the disinfection cavity 101 through the bottom plate 11, and transfer another part of the heat to the first energy storage box 41, and store the heat through the first energy storage box 41. At the same time, the heat dissipated outward by the bottom plate 11 can also be transferred to the first energy storage box 41 through the heat-conducting structure 30, thereby reducing heat loss. During the drying and opening process of the disinfection cabinet 100, when the heating element 20 is on standby or turned off, the heat in the energy storage structure 40 can be slowly released into the disinfection cavity 101, thereby extending the drying time. When the disinfection cabinet 100 is not turned on for drying, the disinfection cabinet 100 can also be kept dry by releasing heat from the energy storage structure 40. The energy storage structure 40 stores and fully utilizes the heat that would otherwise be lost to the outside, thereby improving energy efficiency.
[0031] In summary, a heat conducting structure 30 and an energy storage structure 40 are provided in the disinfection cabinet 100, so that the heat emitted by the heating element 20 toward the bottom plate 11 and lost to the outside can be fully absorbed and reused through the heat conducting structure 30, and the excess heat can be stored through the energy storage structure 40, so as to further reduce heat loss, improve energy efficiency, and achieve long-term energy saving.
[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, in an optional embodiment, the heat-conducting structure 30 is provided with a first heat-conducting portion 31, and one end of the first heat-conducting portion 31 is wrapped around the side of the heating element 20 facing the bottom plate 11. In this way, the heat-conducting structure 30 itself has a high thermal conductivity, and the heat of the heating element 20 facing the bottom plate 11 is fully absorbed through the first heat-conducting portion 31. The first heat-conducting structure 30 is wrapped around the heating element 20, so that the heat of the heating element 20 facing the bottom plate 11 is concentrated, so as to increase the thermal expansion pressure of the heating element 20 facing the bottom plate 11, so as to accelerate the heat dissipation into the disinfection chamber 101, and improve the temperature rise rate in the disinfection chamber 101.
[0033] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, further, the heat-conducting structure 30 is also provided with a second heat-conducting part 32 connected to the first heat-conducting part 31, and the second heat-conducting part 32 is arranged at one end of the first heat-conducting part 31 away from the heating element 20, and the second heat-conducting part 32 is arranged between the bottom plate 11 and the energy storage structure 40. The heat absorbed by the first heat-conducting part 31 can be transferred to the second heat-conducting part 32, and the second heat-conducting part 32 can transfer the heat to the bottom plate 11, and the heat is dissipated into the disinfection chamber 101 by the second heat-conducting part 32 and / or the bottom plate 11 to achieve the reuse of heat and reduce heat loss. At the same time, the second heat-conducting part 32 can also transfer heat to the energy storage structure 40 to achieve the storage of excess heat, and the heat lost to the outside of the bottom plate 11 can also be transferred to the energy storage structure 40 through the second heat-conducting part 32, so as to further reduce heat dissipation and improve energy efficiency.
[0034] like Figure 2 , Figure 3 and Figure 6 As shown, in an optional embodiment, a cover body 50 is provided on the side of the heating element 20 facing the disinfection chamber 101. The cover body 50 is covered on the heating element 20 and together with the first heat conducting part 31, a heat chamber 102 is formed. The heating element 20 is arranged in the heat chamber 102. In this way, the heating element 20 is fully wrapped, so that the heat emitted by the heating element 20 is more concentrated, and the heat loss is further reduced. At the same time, the thermal expansion pressure in the heat chamber 102 is further increased, so that the heat rises faster, thereby improving the heating rate in the disinfection chamber 101.
[0035] like Figure 3 and Figure 6 As shown, in a specific embodiment, the first heat conducting part 31 includes a plurality of heat conducting sheets 311 arranged at intervals, and each heat conducting sheet 311 is arranged at an angle with the second heat conducting part 32. In this way, the plurality of heat conducting sheets 311 can transfer heat together to improve the heat transfer efficiency. At the same time, the sheet-like structure of the heat conducting sheet 311 has a large surface area, which is conducive to the full absorption of heat. In order to facilitate processing, the heat conducting sheet 311 and the second heat conducting part 32 are arranged vertically.
[0036] In a specific embodiment, the second heat conducting part 32 is configured as a heat conducting plate. The plate-shaped structure has a large surface area and can be fully fitted with the bottom plate 11 to transfer heat evenly, which is beneficial for the bottom plate 11 to evenly transfer heat to the disinfection chamber 101, promote uniform increase in temperature in the disinfection chamber 101, and facilitate uniform drying of tableware.
[0037] In a specific embodiment, the heating element 20 is configured as a heating tube. Along the first direction, the size of the first heat-conducting portion 31 along the second direction gradually decreases from the edge of the heating tube toward the center of the heating tube. This configuration is conducive to forming a wrapping state of the first heat-conducting portion 31 on the heating tube, so that the first heat-conducting portion 31 can adapt to the shape of the heating tube, increase the contact area of the first heat-conducting portion 31 toward the heating tube, and promote sufficient absorption and transfer of heat.
[0038] The first direction, the second direction and the axial direction of the heating tube are arranged at angles in pairs. For ease of explanation, the first direction is the direction of one side of the cross section of the disinfection cabinet 100, the second direction is the height direction of the disinfection cabinet 100, the axial direction of the heating tube is the direction of the other side of the cross section of the disinfection cabinet 100, the first direction, the second direction and the axial direction of the heating tube are arranged perpendicularly in pairs, the first direction is the x-axis, the axial direction of the heating tube is the y-axis, and the second direction is the z-axis.
[0039] In a specific embodiment, the heat-conducting structure 30 can be made of heat-conducting materials such as copper and aluminum.
[0040] In a specific embodiment, the first energy storage box 41 is provided with a first opening, and the side wall of the first energy storage box 41 is bent toward the first opening to form a first bending section. The second heat conducting part 32 can extend from the first opening into the first energy storage cavity 411, so that the second heat conducting part 32 and the first energy storage cavity 411 can directly exchange heat, and the heat transfer is faster, reducing intermediate losses. The second heat conducting part 32 is fitted with the first bending section, and the first bending section is pressed between the second heat conducting part 32 and the bottom plate 11, which is conducive to the limited assembly of the first bending section. The second heat conducting part 32 is fitted with the bottom plate 11 on the surface of the first opening facing the disinfection cavity 101 to achieve heat transfer toward the bottom plate 11.
[0041] When the disinfection cabinet 100 is in the drying on state, the heat-conducting structure 30 absorbs the heat of the heating element 20 and transfers part of the heat to the first energy storage box 41 for storage to further reduce heat loss. When the temperature in the disinfection chamber 101 reaches the drying temperature preset by the user, the heating element 20 stops working, and the temperature in the disinfection chamber 101 gradually decreases. When the temperature in the disinfection chamber 101 is lower than the temperature in the first energy storage box 41, the first energy storage box 41 can release heat to the disinfection cabinet 100 to slow down the temperature drop in the disinfection chamber 101, delay the time for the heating element 20 to be turned on again, effectively reduce the time the heating element 20 is turned on, and help reduce energy efficiency and achieve energy-saving drying.
[0042] When the disinfection cabinet 100 is in the drying closed state, the heating element 20 does not work. At this time, the first energy storage box 41 can absorb the heat in the first energy storage cavity 411 through the heat-conducting structure 30 and release the heat into the disinfection cavity 101, so that the disinfection cavity 101 can have a certain temperature, which is conducive to keeping the disinfection cavity 101 dry and reducing the growth of bacteria. At the same time, the heat stored in the first energy storage box 41 is limited, and the bottom plate 11 and the heat-conducting structure 30 each have a large heat-conducting area, which can release the heat evenly, so that the local temperature of the pull-out basket near the heating element 20 is relatively mild, avoiding burns when users take tableware.
[0043] like Figures 1 to 4 As shown, in a further embodiment, the energy storage structure 40 further includes a second energy storage box 42, which is disposed on the side of the bottom plate 11 facing the disinfection chamber 101 and is provided with a second energy storage chamber 421, and the first energy storage chamber 411 and the second energy storage chamber 421 together form an energy storage space. This arrangement further increases the energy storage space, increases heat storage, and further reduces heat loss.
[0044] Furthermore, the bottom plate 11 is provided with a first circulation hole, the heat-conducting structure 30 is provided with a second circulation hole 321, and the first energy storage chamber 411 and the second energy storage chamber 421 are connected through the first circulation hole and the second circulation hole 321, so that the heat in the first energy storage chamber 411 can flow to the second energy storage chamber 421 for storage. When the heat in the first energy storage box 41 is consumed to the point where the temperature of the first energy storage chamber 411 is close to the temperature of the disinfection chamber 101, the second energy storage box 42 can continue to release heat to extend the drying effect. When the disinfection cabinet 100 is powered off, the long-term drying function can still be achieved through the heat release of the first energy storage box 41 and the second energy storage box 42.
[0045] like Figure 5 As shown, in a specific embodiment, the second heat conducting portion 32 is provided with a second flow hole 321 .
[0046] In a specific embodiment, the space of the second energy storage box 42 is smaller than the space of the first energy storage box 41, and the second energy storage box 42 is provided with a second opening toward the first energy storage box 41, the first circulation hole and the second circulation hole 321 can be respectively communicated with the second opening, and the end at the second opening is connected to the second heat conducting part 32, and the heat in the second energy storage box 42 can be transferred from the second heat conducting part 32 to the bottom plate 11, and then dissipated from the bottom plate 11 to the disinfection chamber 101. Since the contact area between the second energy storage box 42 and the second heat conducting part 32 is relatively small, the heat in the second energy storage box 42 can be slowly transferred to the second heat conducting part 32 to achieve slow release of heat, so that the disinfection chamber 101 can maintain a dry effect for a long time.
[0047] In some embodiments, at least two heating elements 20 are provided, and at least two heating elements 20 are arranged at intervals, and a second energy storage box 42 is provided between any two adjacent heating elements 20. In this way, the space between two adjacent heating elements 20 can be fully utilized to improve the utilization rate of the space.
[0048] In a specific embodiment, the first energy storage box 41 and the second energy storage box 42 can respectively use heat-insulating materials, such as polyurethane, polystyrene foam, etc.
[0049] In a specific embodiment, the first energy storage box 41 and the second energy storage cavity 421 are respectively filled with energy storage media, such as air, water, oil, etc.
[0050] like Figure 2 As shown, in an optional embodiment, an adjustment mechanism 60 is provided at the first circulation hole or the second circulation hole 321, and the adjustment mechanism 60 is used to adjust the on-off of the first energy storage cavity 411 and the second energy storage cavity 421 to achieve precise control of heat transfer therebetween.
[0051] Further, the regulating mechanism 60 is configured to control the first energy storage chamber 411 and the second energy storage chamber 421 to be connected in response to the temperature of the first energy storage chamber 411 reaching the first temperature, and to control the first energy storage chamber 411 and the second energy storage chamber 421 to be disconnected when the temperature of the first energy storage chamber 411 is lower than the first temperature. Specifically. When the temperature in the first energy storage chamber 411 reaches the first temperature, the heat in the first energy storage chamber 411 can enter the second energy storage chamber 421 for storage, thereby increasing the storage space for heat. When the temperature in the first energy storage chamber 411 is lower than the first temperature, the heat in the first energy storage chamber 411 is insufficient, and at this time, the connection between the first energy storage chamber 411 and the second energy storage chamber 421 is disconnected in time, so that the heat in the second energy storage chamber 421 will not flow back to the first energy storage chamber 411. By setting the specific first temperature, the regulation of the regulating mechanism 60 has a clear basis, making the regulation more precise.
[0052] like Figure 5As shown, in a specific embodiment, the adjustment mechanism 60 includes a first metal sheet 61 and a second metal sheet 62, the first metal sheet 61 is arranged in the first energy storage cavity 411, and the second metal sheet 62 is arranged in the second energy storage cavity 421; the thermal expansion coefficient of the first metal sheet 61 is smaller than the thermal expansion coefficient of the second metal sheet 62, and the deformation of the first metal sheet 61 is greater than the deformation of the second metal sheet 62, so that the second metal sheet 62 can be pushed open by the deformation of the first metal sheet 61.
[0053] Furthermore, the first metal sheet 61 can be bent and deformed toward the second metal sheet 62 after the first energy storage cavity 411 reaches the first temperature, and the second metal sheet 62 can rotate under the push of the first metal sheet 61 to open the first circulation hole or the second circulation hole 321. In this way, the first metal sheet 61 can be deformed according to the temperature change, so that when the temperature in the first energy storage cavity 411 reaches above the first temperature, the second metal sheet 62 can be pushed open, so that the second metal sheet 62 cancels the blockage of the first circulation hole or the second circulation hole 321, and the connection between the first energy storage cavity 411 and the second energy storage cavity 421 is realized; and the first metal sheet 61 is reset when the temperature in the first energy storage cavity 411 is lower than the first temperature, and the second metal sheet 62 can restore the blockage of the first circulation hole or the second circulation hole 321 after the first metal sheet 61 is reset, so that the first energy storage cavity 411 and the second energy storage cavity 421 are disconnected. The whole process does not require electrical control, and the structures of the first metal sheet 61 and the second metal sheet 62 are simple and compact, which can reduce the occupied space.
[0054] like Figure 5 As shown, in a specific embodiment, the first flow hole is larger than the second flow hole 321, the second heat conducting part 32 can be directly exposed to the second energy storage cavity 421, the second metal sheet 62 is rotatably connected to the surface of the second heat conducting part 32 facing the second energy storage cavity 421, and the first metal sheet 61 is connected to the surface of the second heat conducting part 32 facing the first energy storage cavity 411. This arrangement is simple to assemble.
[0055] In a specific embodiment, the thermal expansion temperature range of the first metal sheet 61 is 50°C to 80°C, that is, the first temperature is the thermal expansion temperature of the first metal sheet 61. In this way, the appropriate thermal expansion temperature range can ensure that the heat in the first energy storage cavity 411 is circulated to the second energy storage cavity 421 in a timely manner, so as to achieve more effective storage of heat. If the thermal expansion temperature is large, it is easy to cause the first metal sheet 61 to remain undeformed when the temperature is high, and the excess heat cannot be stored in the second energy storage box 42 in time, resulting in heat loss; if the thermal expansion temperature is small, it is easy to cause the first metal sheet 61 to deform when the temperature of the first energy storage cavity 411 is low, so that the heat in the first energy storage cavity 411 cannot be well stored.
[0056] Exemplarily, the thermal expansion temperature of the first metal sheet 61 is 50°C, 60°C or 80°C.
[0057] When the disinfection cabinet 100 is in the drying on state, the heating element 20 continues to work, and the second heat conducting part 32 continuously transfers heat to the first energy storage cavity 411. The heat in the first energy storage cavity 411 continues to rise, and the temperature in the first energy storage cavity 411 reaches the first temperature, that is, the first metal sheet 61 reaches its own thermal expansion temperature. The first metal sheet 61 bends and deforms to push the second metal sheet 62 to rotate, so as to open the second circulation hole 321, so as to connect the first energy storage cavity 411 with the second energy storage cavity 421. The heat in the first energy storage cavity 411 can be transferred to the second energy storage cavity 421, so as to realize the storage of heat in the second energy storage cavity 421.
[0058] When the disinfection cabinet 100 is in the drying closed state, when the drying is just closed, the temperature in the first energy storage chamber 411 is consistent with that in the second energy storage chamber 421, and the first metal sheet 61 and the second metal sheet 62 are still in the open state. The first energy storage chamber 411 and the second energy storage chamber 421 release heat to the outside through the heat conduction structure 30 to keep the disinfection chamber 101 in a dry state. With the continuous release of heat, the temperature in the first energy storage chamber 411 and the second energy storage chamber 421 continues to decrease. When the temperature in the first energy storage chamber 411 is lower than the first temperature, the first metal sheet 61 returns to its original state under the pressure of the second metal sheet 62, and the second metal sheet 62 blocks the second flow hole 321, and the first energy storage chamber 411 and the second energy storage chamber 421 are disconnected. At this time, since the contact area between the first energy storage box 41 and the second heat conduction part 32 is greater than the contact area between the second energy storage box 42 and the second heat conduction part 32, the heat in the first energy storage box 41 is dissipated to the disinfection chamber 101 faster than the heat in the second energy storage box 42. The first energy storage box 41 continues to emit heat until the temperature in the first energy storage box 41 is consistent with the temperature in the disinfection chamber 101. At this time, the second energy storage box 42 continues to release heat to the outside. Since the contact area between the second energy storage box 42 and the second heat conducting part 32 is small, the second energy storage box 42 transfers heat to the bottom plate 11 through the second heat conducting part 32, and then transfers it to the disinfection chamber 101 from the bottom plate 11. The heat can be released slowly to keep the disinfection chamber 101 dry for a long time.
