TECHNICAL FIELD
[0001] The utility model relates to the field of disinfection cabinet, in particular to a disinfection cabinet. BACKGROUND
[0002] The disinfection cabinet comprises a cabinet body, a support rod and a supporting plate, the support rod is arranged on the inner wall of the cabinet body, and the supporting plate is supported on the support rod at the edge. During the disinfection and drying of tableware, the tableware is placed on the supporting plate, and water drops on the tableware will first flow along the upper surface of the supporting plate to the edge of the supporting plate, and then part of the water drops will flow to the support rod, causing part of the support rod to accumulate water. Since the heating area in the cabinet body is mainly concentrated in the center position, that is, close to the center position of the supporting plate, the heat at the position of the support rod is insufficient, therefore, after the disinfection and drying process of the tableware is completed, the support rod is often relatively humid, and if secondary drying is not performed in time, bacteria will easily breed. SUMMARY
[0003] Therefore, it is necessary to provide a disinfection cabinet aiming at the problem that the support rod is still relatively humid after the disinfection and drying process of tableware is completed.
[0004] A disinfection cabinet comprises a cabinet body, a support rod and a semiconductor refrigeration sheet.
[0005] A disinfection chamber is arranged in the cabinet body, and a first exhaust hole is arranged on the side wall of the disinfection chamber.
[0006] An exhaust groove is arranged in the support rod, a second exhaust hole and a third exhaust hole are arranged on the outer wall of the support rod, the second exhaust hole and the third exhaust hole both penetrate the exhaust groove, the support rod is arranged on the side wall of the disinfection chamber, so that the third exhaust hole is located at the first exhaust hole and communicates with the first exhaust hole.
[0007] The semiconductor refrigeration sheet has a hot end and a cold end, the hot end is arranged on the support rod, and the cold end is located outside the disinfection chamber, so as to cool the hot air at the first exhaust hole.
[0008] A sponge is arranged on the cold end.
[0009] The hot end is at least partially located at the second exhaust hole.
[0010] A plug-in pipe is arranged at the third exhaust hole, and the plug-in pipe is plugged in the first exhaust hole.
[0011] The cold end is fixed on the cabinet body, and the cold end clamps the plug-in pipe.
[0012] The support rod of this utility model is further provided with a water collection trough, which is spaced apart from the venting trough. The top side wall of the water collection trough is provided with a water collection hole, which extends to the outer wall of the support rod. The outer wall of the support rod is provided with a support rib, which is located at the edge of the water collection hole.
[0013] The hot end of this invention is located at least partially on the bottom outer wall of the support rod.
[0014] The exhaust groove of this invention extends along the axial direction of the support rod and passes through both ends of the support rod.
[0015] The disinfection cabinet of this utility model also includes a tray, the edge of which is supported on the supporting ribs, so that the second exhaust hole and the water collection hole are spaced apart on the tray.
[0016] The top wall of the exhaust groove of this invention is located above the supporting rib, and the water collection hole is located between the supporting rib and the exhaust groove.
[0017] The beneficial effects of this utility model are as follows:
[0018] The heating element heats the entire support rod, causing the water on it to evaporate and improving its drying effect. Furthermore, the high air temperature and humidity at the support rod location cause the evaporating water vapor to spontaneously flow into the exhaust duct through the second exhaust port, and then exit the disinfection chamber through the third and first exhaust ports. This prevents excessive humidity at the support rod location, ensuring that the evaporation efficiency of the water on the support rod remains consistently high.
[0019] At the same time, the cold end can reduce the temperature of the air flowing out of the first exhaust port, preventing users from being scalded by the hot air flowing out of the first exhaust port. Based on the cooling effect of the cold end, the temperature difference between the support rod and the outside of the disinfection room can be further increased, so as to further accelerate the discharge of water vapor formed by evaporation at the support rod to the outside of the disinfection room.

[0046] Embodiment:
[0047] Referring to Figure 1 , Figure 4 and Figure 7 , the present embodiment provides a disinfection cabinet, comprising a cabinet body 1, a support rod 2, a semiconductor refrigerating sheet 3 and a supporting plate 4.
[0048] Among them, the cabinet body 1 is provided with a disinfection chamber 11, the disinfection chamber 11 is provided with an ultraviolet lamp and a heater, usually the ultraviolet lamp is located at the top of the disinfection chamber 11, the heater is located at the bottom of the disinfection chamber 11. The support rod 2 is installed on the side wall of the disinfection chamber 11, the edge of the supporting plate 4 can be supported on the support rod 2, and the tableware is supported on the upper surface of the supporting plate 4 during the disinfection and drying process. Among them, based on the installation position of the existing heater in the disinfection chamber 11, the heat generated by the heater is mainly conducted to the middle position of the supporting plate 4 through the air for the drying of tableware, and in contrast, the heat conducted to the support rod 2 is relatively small.
[0049] Referring to Figures 13-18 , the support rod 2 is in a strip shape, the support rod 2 is provided with an exhaust groove 21, and the outer wall of the support rod 2 is provided with a second exhaust hole 22 and a third exhaust hole 23, both of which are communicated with the exhaust groove 21. Figure 2 and Figure 3 , after the support rod 2 is installed on the side wall of the disinfection chamber 11, the exhaust groove 21 can be communicated with the disinfection chamber 11 through the second exhaust hole 22. Referring to Figures 7-9The first exhaust hole is arranged on the side wall of the sterilization chamber 11. After the support rod 2 is arranged on the side wall of the sterilization chamber 11, the third exhaust hole 23 is arranged at the first exhaust hole and communicates with the first exhaust hole. Thus, the exhaust groove 21 can communicate with the outside of the sterilization chamber 11 through the third exhaust hole 23 and the first exhaust hole.
[0050] Referring to Figures 10-12 The semiconductor refrigeration sheet 3 has a hot end 31 and a cold end 32. The hot end 31 can be used for heating, and the cold end 32 can be used for refrigeration. The hot end 31 is arranged on the support rod 2 to allow the hot end 31 to heat the support rod 2. Referring to Figures 4-9 The cold end 32 is arranged on the cabinet 1 and located outside the sterilization chamber 11. The cold air generated by the cold end 32 can flow to the vicinity of the first exhaust hole.
[0051] Referring to Figure 3 , Figure 6 and Figure 9 During the sterilization and drying of the tableware, part of the water droplets on the surface of the tableware flow along the upper surface of the supporting plate 4 to the support rod 2, causing water accumulation on the support rod 2. At this time, the hot end 31 can be in contact with the support rod 2 and conduct heat, thereby assisting in heating the entire support rod 2 and promoting the evaporation of the water on the support rod 2, thereby improving the drying effect of the support rod 2.
[0052] Based on the heating effect of the hot end 31, the air at the support rod 2 has a high humidity and a high temperature. Thus, a large humidity difference and temperature difference are formed between the air at the support rod 2 and the air outside the sterilization chamber 11. After the water on the support rod 2 evaporates, the water can spontaneously flow into the exhaust groove 21 through the second exhaust hole 22 and then be discharged from the sterilization chamber 11 through the third exhaust hole 23 and the first exhaust hole. Thus, the humidity of the air at the support rod 2 can be prevented from being too high, and the evaporation efficiency of the water on the support rod 2 can always be maintained at a high level. Furthermore, the cold end 32 can cool the high-temperature air discharged from the first exhaust hole, thereby preventing the high-temperature air from scalding the user. Furthermore, based on the cooling effect of the cold end 32, the temperature difference between the air at the support rod 2 and the air outside the sterilization chamber 11 can be further increased, thereby accelerating the discharge of the water vapor formed by the evaporation of the water at the support rod 2 to the outside of the sterilization chamber 11.
[0053] In some other embodiments, a sponge is arranged on the cold end 32. During the refrigeration of the cold end 32, condensate water can be formed at the first exhaust hole. At this time, the sponge can absorb the condensate water, thereby preventing the condensate water from dripping.
[0054] Based on the foregoing analysis, the water vapor formed by the evaporation at the support rod 2 needs to first enter the exhaust groove 21 through the second exhaust hole 22 before being discharged from the sterilization chamber 11 through the third exhaust hole 23 and the first exhaust hole. Based on this, referring to Figure 12, the hot end 31 is at least partially located at the second exhaust hole 22. Based on this, the water vapor will be heated again by the hot end 31 when entering the exhaust groove 21 through a part of the second exhaust hole 22, ensuring that the air in the exhaust groove 21 can maintain a high temperature before reaching the first exhaust hole, so as to avoid the formation of condensate as much as possible before the air leaves the exhaust groove 21.
[0055] Referring to Figures 7-9 , Figure 16 and Figure 17 , as a preferred, the third exhaust hole 23 is provided with a plug-in pipe 231, the end of the plug-in pipe 231 communicates with the third exhaust hole 23, and the plug-in pipe 231 is plugged in the first exhaust hole, thereby ensuring that the third exhaust hole 23 can be aligned and communicated with the first exhaust hole. Moreover, the plug-in cooperation of the plug-in pipe 231 and the first exhaust hole also increases the connection stability of the support rod 2 on the side wall of the disinfection chamber 11.
[0056] Referring to Figure 8 , Figure 9 and Figure 11 , in this embodiment, the cold end 32 is in the form of a fin and is fixed on the cabinet 1, so that the cold end 32 can clamp the plug-in pipe 231. In this way, the cold end 32 not only can directly contact with the plug-in pipe 231 to more effectively cool the high-temperature air in the plug-in pipe 231, but also further improves the stability of the plug-in pipe 231 at the first exhaust hole.
[0057] Preferably, the exhaust groove 21 extends along the axial direction of the support rod 2 and penetrates to both ends of the support rod 2, so as to allow the user to place long-shaped tableware such as chopsticks in the exhaust groove 21 to obtain the heating and drying of the hot end 31. Compared with placing such long-shaped tableware on the supporting plate 4, such long-shaped tableware is less likely to fall in the exhaust groove 21.
[0058] Referring to Figures 13-18 , as a preferred embodiment, the support rod 2 is further provided with a water collecting groove 24. As a specific example, the water collecting groove 24 also extends along the axial direction of the support rod 2, and the end of the water collecting groove 24 can be sealed by a sealing cover. Among them, the water collecting groove 24 and the exhaust groove 21 are arranged in a horizontal direction, and the water collecting groove 24 and the exhaust groove 21 are separated by a partition plate. The top side wall of the water collecting groove 24 is provided with a water collecting hole 241, and the water collecting hole 241 penetrates to the outer wall of the support rod 2. At the same time, the outer wall of the support rod 2 is provided with a support rib 25, and the support rib 25 is located at the edge of the water collecting hole 241.
[0059] Referring to Figure 3 , Figure 6 and Figure 9, the lower surface edge of the tray 4 is supported on the support rib 25 to prevent the tray 4 from blocking the water collecting hole 241 and the second air outlet hole 22, and to ensure that the second air outlet hole 22 and the water collecting hole 241 are spaced apart on the tray 4. For a portion of the water droplets falling from the tableware, the flow path is as indicated by the dashed arrow in Figure 9 Specifically, the water droplets first flow along the upper surface of the tray 4 to the side edge of the tray 4, then flow to the lower surface of the tray 4, and are blocked by the support rib 25, and then flow along the support rib 25 and the outer wall of the support rod 2 to the water collecting hole 241, and finally are collected into the water collecting groove 24 through the water collecting hole 241. The above structure can effectively reduce the occurrence of water droplets falling from the upper surface of the tray 4 to the lower surface of the tray 4. Based on the heating effect of the hot end 31, the water droplets in the water collecting groove 24 evaporate and can leave the water collecting groove 24 through the water collecting hole 241. Since the water collecting hole 241 and the second air outlet hole 22 are both on the support rod 2, they are close to each other, and the water vapor can quickly pass through the second air outlet hole 22 into the air outlet groove 21 after leaving the water collecting groove 24, and finally leave the sterilization chamber 11.
[0060] Considering the effect of gravity, the water droplets in the water collecting groove 24 are concentrated at the bottom of the water collecting groove 24. In order to accelerate the evaporation of the water droplets in the water collecting groove 24, the hot end 31 is at least partially located at the bottom outer wall of the support rod 2, especially the portion where the bottom of the water collecting groove 24 is located. Since a portion of the second air outlet hole 22 is located at the bottom of the air outlet groove 21 in the embodiment, the hot end 31 almost completely covers the entire bottom outer wall of the support rod 2 in the embodiment.
[0061] Continuing to refer to Figure 9 In the embodiment, the top wall of the air outlet groove 21 is located above the support rib 25, and the water collecting hole 241 is located between the support rib 25 and the air outlet groove 21, so that the water droplets flowing along the support rib 25 are limited between the support rib 25 and the air outlet groove 21, and a portion of the outer wall of the support rod 2 limits the water droplets, so that the water droplets flowing along the support rib 25 can all finally enter the water collecting groove 24 through the water collecting hole 241.
[0062] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
[0063] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
