[0034] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those commonly understood by those skilled in the art of the technical field of this application. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0035] Most existing disinfection cabinets place heating elements at the bottom of the inner tank to heat and dry the tableware in the cavity. This may cause users to hit the heating elements when placing tableware, or even damage them; and some smaller tableware may accidentally fall onto the heating elements during use, causing them to be damaged. At the same time, it is also possible that some tableware that is not resistant to high temperatures, such as plastic, may be burned or melted when accidentally dropped, and in serious cases, may cause accidents such as smoke or fire.

[0036] In response to this, some manufacturers use the method of adding a protective cover to the outside of the heating element to protect the heating tube; in this way, even if the tableware falls due to improper placement, or residual liquid on the tableware drips, it will be intercepted by the protective cover to prevent it from directly contacting the heating element and damaging the heating element. However, it is precisely because the protective cover is above the heating element that it has a certain blocking effect on the heat dissipation of the heating element. Although some methods use holes in the protective cover to increase the diffusion amount. However, the area between the heat dissipation holes on the protective cover will still block the heating element, thereby consuming some heat. In addition, when the heating tube is heated, the heat is dissipated into the gallbladder cavity through the protective cover and the openings, causing the protective cover itself to be too hot. When cleaning, burns and other problems are inevitable.

[0037] Based on the above problems, an embodiment of the present application provides a heating structure for a disinfection cabinet, which not only protects the heating element, but also reduces the impact on heat transfer and improves heat utilization, and can ensure that the temperature of the protective cover is appropriate to avoid scalding. The heating structure for the disinfection cabinet is described in detail below.

[0038] See also Figure 1 , Figure 2 , Figure 7 and Figure 8An embodiment of the present application provides a heating structure 100 for a disinfection cabinet, including a mounting bracket 110, a heating tube 120 and a protective cover 130. The mounting bracket 110 is configured with an assembly cavity 1101 and a cooling cavity 1102 connected to the assembly cavity 1101. The heating tube 120 is mounted on the mounting bracket 110 and accommodated in the assembly cavity 1101. The protective cover 130 is rotatably arranged on the mounting bracket 110. The protective cover 130 has a shielding state and a cooling state. In the shielding state, the protective cover 130 shields the heating tube 120; in the cooling state, the protective cover 130 releases the shielding of the heating tube 120 and is at least partially located in the cooling cavity 1102.

[0039] It can be understood that the mounting bracket 110 is used to ensure the mounting reference and mounting stability of the heating tube 120 and the protective cover 130, and the assembly cavity 1101 is used to protect the heating tube 120; at the same time, the setting of the protective cover 130 further ensures that the heating tube 120 is not affected by the collision of tableware. Specifically, due to the rotation setting of the protective cover 130, it is convenient to adjust the position of the protective cover 130 relative to the heating tube 120. When heating is not required, the protective cover 130 can be rotated to cover the heating tube 120, thereby increasing the protection of the heating tube 120. At this time, when taking and placing tableware, it is ensured that the tableware in the disinfection cabinet will not easily bump into the heating tube 120 and cause damage to the heating tube 120. When heating and drying are required, the protective cover 130 can be rotated to remove the shielding of the heating tube 120, and the heat of the heating tube 120 can be fully dissipated to the dishes in the disinfection cabinet, thereby improving the heat utilization rate; at the same time, due to the setting of the cooling cavity 1102, the protective cover 130 can be rotated to the cooling cavity 1102, and at least partially located in the cooling cavity 1102, so as to keep the protective cover 130 cool, avoid the problem of overheating of the protective cover 130 caused by the heat of the heating tube 120, and avoid scalding problems as much as possible. In this way, the service life and safety of use can be extended.

[0040] Exemplarily, the cooling chamber 1102 is located below the heating tube 120, and a coolant is stored in the cooling chamber 1102; in the cooling state, at least part of the protective cover 130 is immersed in the coolant. In this way, the protective cover 130 rotates to the bottom of the heating tube 120 in the cooling state to contact the coolant; and rotates to the top of the heating tube 120 in the shielding state to shield the heating tube 120. The coolant can be water. At this time, the cooling chamber 1102 can be connected to a water supply structure to ensure that the water in the cooling chamber 1102 is as low as possible to meet the heat dissipation of the protective cover 130.

[0041] Alternatively, the cooling chamber 1102 may be air-cooled, in which case the cooling chamber 1102 may be disposed not only below the heating tube 120 but also at the side, etc., as long as it can avoid the direction in which the heating tube 120 directly acts on the gallbladder cavity.

[0042] See also Figures 1 to 3 In some embodiments, along the radial direction of the heating tube 120, a plurality of heat dissipation protrusions 133 arranged at intervals along the axial direction of the heating tube 120 are convexly provided on the side of the protective cover 130 facing away from the heating tube 120. The provision of the heat dissipation protrusions 133 increases the contact area between the protective cover 130 itself and the cooling amount in the cooling chamber 1102, thereby increasing the cooling effect. In some specific embodiments, the protective cover 130 has an inner side 1301 and an outer side 1302, the inner side 1301 faces the heating tube 120, and the heat dissipation protrusions 133 are formed by being recessed from the inner side 1301 toward the outer side 1302. In other words, a plurality of heat dissipation protrusions 133 arranged at intervals can be integrally formed directly on the protective cover 130 by stamping to meet the heat dissipation and cooling requirements.

[0043] Alternatively, a plurality of heat dissipation fins arranged at intervals along the axial direction of the heating tube 120 may be protruded from the side of the protective cover 130 facing away from the heating tube 120 , as long as the heat dissipation effect can be enhanced.

[0044] like Figures 1 to 3 As shown, in actual use, the heating tube 120 is arranged in the horizontal direction, and the X-axis direction can be the axial direction of the heating tube 120, and the Z-axis direction is the vertical direction. The length of the protective cover 130 is along the axial direction of the heating tube 120, so that the heating tube 120 can be fully shielded in the shielding state to improve the protection. If the heating tube 120 is not easily damaged, it is equivalent to extending the service life. The protective cover 130 includes a connecting portion 132 and an arc portion 131, and the two ends of the arc portion 131 along the X-axis direction are connected to the connecting portion 132, and the connecting portion 132 is used for rotatable connection with the mounting bracket 110 to meet the support and rotation of the protective cover 130. The shape of the arc portion 131 is compatible with the heating tube 120, and is used to shield the heating tube 120 or to contact the cold in the cooling chamber 1102 for cooling. At the same time, due to the arrangement of the arc-shaped portion 131, when the arc-shaped portion 131 is rotated to a certain position, the heat of the heating tube 120 can be reflected so that the heat can be more fully dissipated into the gallbladder cavity.

[0045] Alternatively, the connecting portion 132 may be connected to only one end of the arc portion 131 along the X-axis direction, as long as the protective cover 130 can be stably assembled.

[0046] Furthermore, the aforementioned plurality of heat dissipation protrusions 133 are arranged on the arc portion 131. The length of each heat dissipation protrusion 133 extends along the arc bending direction of the arc portion 131 (i.e., the circumferential direction of the heating tube 120). Such an arrangement may also be equivalent to providing a plurality of spaced ribs on the protective cover 130, and may also increase the structural strength of the protective cover 130 itself. Alternatively, each heat dissipation protrusion 133 may be hemispherical.

[0047] like Figure 3 As shown, further, taking the arc portion 131 connected to two connecting portions 132 as an example, the two connecting portions 132 can be fan-shaped or fan-shaped. The two connecting portions 132 have connecting flanges 1321 extending along the axial direction of the heating tube 120 on opposite sides, and the two ends of the arc portion 131 can be pressed on the connecting flanges 1321 on the same side.

[0048] Please continue reading Figures 1 to 3 In an optional embodiment, the mounting bracket 110 includes a mounting box body 111 and a support seat 112; the mounting box body 111 is enclosed to form an assembly cavity 1101, and the mounting box body 111 is recessed at the bottom of the assembly cavity 1101 along the radial direction of the heating tube 120 toward the side away from the heating tube 120 to form a cooling cavity 1102, and the support seat 112 is installed on the mounting box body 111, and connects the heating tube 120 and the protective cover 130. Such a setting simplifies the structure and facilitates production. The mounting box body 111 includes two first side plates 1111 that are opposite and spaced apart in the X-axis direction, two second side plates 1112 that are opposite and spaced apart in the Y-axis direction, and a bottom plate 1113 connected between the two first side plates 1111 and the two second side plates 1112. In this way, an assembly cavity 1101 with an open top can be enclosed. The bottom plate 1113 can be stamped to form a groove as the cooling cavity 1102, and the notch of the groove is connected to the assembly cavity 1101. The support seat 112 can be connected to the bottom plate 1113, and is close to the edge of the notch, and is not arranged in the groove. The support seat 112 is used to support the heating tube 120 and the protective cover 130.

[0049] In some specific embodiments, the two second side plates 1112 can be arranged to be tilted toward each other from top to bottom along the vertical direction, so that the distance between the two along the Y-axis direction gradually decreases from top to bottom. In this case, the two second side plates 1112 can serve as the radiation surface of the heat of the heating tube 120, and a plurality of radiation strips 113 can be arranged at intervals on the two second side plates 1112 to improve the radiation effect of heat.

[0050] like Figure 3 As shown, two support seats 112 are provided, and are arranged oppositely and at intervals along the axial direction of the heating tube 120. The axial ends of the heating tube 120 and the two ends of the protective cover 130 are respectively connected to the support seats 112 on the same side, so as to improve the support for the heating tube 120 and the protective cover 130. Furthermore, an elastic gasket 114 is installed between each support seat 112 and the installation box body 111. In this way, the support seat 112 can be in elastic contact with the installation box body to reduce the vibration generated by the disinfection cabinet during transportation or handling, and improve the protection of the heating tube 120 and the protective cover 130.

[0051] like Figure 3As shown, in some embodiments, the heating tube 120 includes a tube body 121 and a seat body 122 connected to the tube body 121, and the seat body 122 is connected to the support seat 112. The connecting portion 132 on the protective cover 130 can also be connected to the seat body 122. At this time, the protective cover 130 also includes a mounting ring 134 connected to the connecting portion 132, and the mounting ring 134 is sleeved on the seat body 122, and can rotate around the axis of the heating tube 120 relative to the seat body 122 to meet the position adjustment of the protective cover 130 relative to the heating tube 120.

[0052] See also Figure 1 , Figure 3 and Fig. 9 Exemplarily, the heating structure 100 for the disinfection cabinet further includes a driving mechanism 140, which is mounted on the support seat 112 and connected to the protective cover 130, and is used to drive the protective cover 130 to rotate. The setting of the driving mechanism 140 facilitates the control of the rotation state of the protective cover 130, and the rotation of the protective cover 130 can be linked to the use state of the disinfection cabinet itself. When taking and placing tableware in the disinfection cabinet, the driving mechanism 140 drives the protective cover 130 to rotate to a shielding state to protect the heating tube 120. When the disinfection cabinet needs to be heated, dried, and disinfected, the driving mechanism 140 drives the protective cover 130 to rotate to a cooling state to cool and dissipate the heat of the protective cover 130 to prevent it from overheating. At the same time, during heating and drying, the driving mechanism 140 can also drive the protective cover 130 to swing back and forth around the axis of the heating tube 120 to reflect the heat of the heating tube 120 in multiple directions and angles, so that the heat in the cavity is more sufficient and the temperature field is more uniform, which is more conducive to the disinfection and drying of tableware at different positions in the disinfection cabinet; this state can be called the radiation state.

[0053] like Figure 3 As shown, the driving mechanism 140 includes a power source 141 and a transmission unit 142 connected to the power source 141. The transmission unit 142 is rotatably sleeved on the seat body 122 of the heating tube 120 and is transmission-connected with the mounting ring 134 of the protective cover 130 to meet the rotation drive. The mounting ring 134 not only serves as the installation and positioning of the protective cover 130 relative to the heating tube 120, but also serves as a power transmission with the driving mechanism 140 to meet the rotation drive of the protective cover 130. Among them, the power source 141 is a motor. The support seat 112 is configured with a mounting cavity 1121, and the motor can be installed in the mounting cavity 1121.

[0054] Optionally, at least a portion of the outer wall 1302 of the mounting ring 134 is configured with a plurality of teeth arranged at intervals around the axis of the heating tube 120, and the transmission unit 142 includes a driving gear 1421, which is meshed with the mounting ring 134 through a plurality of teeth. Alternatively, the transmission unit 142 includes a driving gear 1421 and a driven gear ring 1422, which are meshed with each other for transmission, the driven gear ring 1422 is connected to the mounting ring 134, and the driving gear 1421 is connected to the power source 141. The driven gear ring 1422 can also be a driven gear.

[0055] The wheel diameter of the driving gear 1421 is smaller than the diameter of the driven gear ring 1422 and the outer diameter of the mounting ring 134. The gear transmission setting facilitates the adjustment of the transmission ratio, thereby adjusting the rotation speed of the protective cover 130 to keep it in a stable and slow state, thereby avoiding the cooling water in the cooling chamber 1102 from being brought out or splashed out. In other embodiments, a belt transmission method can also be used, and the mounting ring 134 can be connected to a pulley to meet the rotation drive.

[0056] See also Figures 4 to 9 The present application also provides a disinfection cabinet, comprising a cabinet body 200, an inner tank 300 and the above-mentioned heating structure 100 for the disinfection cabinet. The cabinet body 200 has a cabinet bottom wall 210, the inner tank 300 is installed in the cabinet body 200 and has a tank bottom wall 310, there is an assembly space 400 between the tank bottom wall 310 and the cabinet bottom wall 210, and the tank bottom wall 310 is configured with a heat dissipation gap 311 penetrating in the vertical direction. The above-mentioned heating structure 100 for the disinfection cabinet is installed in the assembly space 400, the assembly cavity 1101 is connected to the tank cavity 3001 of the inner tank 300 through the heat dissipation gap 311, and the cooling cavity 1102 and the heat dissipation gap 311 are respectively arranged on both sides of the heating tube 120 in the vertical direction; in the shielding state, the protective cover 130 rotates to the top of the heating tube 120 and is located at the heat dissipation gap 311, and in the cooling state, the protective cover 130 rotates to the bottom of the heating tube 120.

[0057] By using the assembly space 400 between the cabinet 200 and the inner tank 300, the installation of the heating structure 100 (hereinafter referred to as the heating structure) for the disinfection cabinet does not need to occupy the space of the gallbladder cavity 3001, and will not affect the use of the lower pull-out basket in the gallbladder cavity 3001; and such an arrangement can cause the lower pull-out basket to be set lower, so as to make full use of the lower space of the gallbladder cavity 3001 and improve the utilization rate of the gallbladder cavity 3001 space. In addition, it is precisely because the heating structure is installed at the assembly space 400 that even if the tableware in the gallbladder cavity 3001 falls, it will directly fall on the gallbladder bottom wall 310, and will not directly act on the heating structure, further improving the protective effect of the heating tube 120. When the disinfection cabinet needs to be heated and dried, the protective cover 130 rotates to a position to avoid the heat dissipation gap 311, so that the heating tube 120 can be exposed to the heat dissipation gap 311, ensuring that the heat is fully dissipated from the heat dissipation gap 311 to the gallbladder cavity 3001. At the same time, the protective cover 130 swings back and forth to increase the uniformity of heat in the cavity 3001 and improve the drying effect; and the protective cover 130 can also rotate to the cooling cavity 1102 to cool it with coolant to prevent heat release. When it is necessary to take or put tableware, the protective cover 130 rotates to the heat dissipation gap 311 to cover the top of the heating tube 120 to prevent the tableware from hitting the heating tube 120 from the heat dissipation gap 311.

[0058] like Figure 5 and Figure 6 As shown, in some embodiments, the bottom wall 310 of the gallbladder is configured with a plurality of heat dissipation holes 312 arranged at intervals near the heat dissipation notch 311, and each heat dissipation hole 312 connects the assembly cavity 1101 and the gallbladder cavity 3001. The arrangement of the plurality of heat dissipation holes 312 increases the heat diffusion range, making it easier for the heating tube 120 to fully act on the tableware in the gallbladder cavity 3001.

[0059] The mounting bracket 110 may be connected to the cabinet 200, or to the inner container 300, or may be connected to both the cabinet 200 and the inner container 300. It only needs to ensure stable assembly of the heating structure.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
