The supporter preferably has frame or network structure, both can the waterlogging caused by excessive rainfall ventilation, can pass through the ultraviolet ray again.

When the supporter with the roof of casing is fixed to be set up, the extending structure of supporter can be through setting up to the support body that stretches out and draws back, or through setting up the supporter is adjustably fixed in different positions in the inslot and is realized. These technical details may be implemented in various specific configurations by those skilled in the art, and thus are not described in detail in this embodiment.

The supporter preferably adopts stainless steel material, has sturdy and durable characteristics.

Obviously, in this embodiment, no rack or other device may be provided in the groove, in which case the shape of the groove matches the shape of the kitchen ware to directly hold the kitchen ware.

Preferably, a draining hole 6 is formed on the bottom surface of the housing, so that liquid or residue attached to the kitchenware can fall down from the draining hole to the lower part of the housing, thereby keeping the disinfection device, especially the interior of the disinfection device clean and sanitary.

In this embodiment, the groove is provided with an LED light source 5, which is arranged at the bottom of the groove as shown in fig. 2. The LED light sources may also be arranged at the sides of the groove, which avoids impurities falling onto the light sources and affecting the light.

In this embodiment, the LED light source is an ultraviolet LED light source, especially a deep ultraviolet LED light source, i.e. UVC-LED, and the ultraviolet light source can effectively kill harmful microorganisms such as bacteria and viruses. Adopt ultraviolet LED light source as the light source that disinfects in this patent, can utilize LED light source luminance height, the little advantage of power consumption at first to the LED light source has small advantage, consequently can arrange in a flexible way in sterilizing equipment's different positions and improve this patent sterilizing equipment's application range to different tableware disinfection under the characteristics that keep sterilizing equipment whole miniaturization.

In this embodiment, preferably, the LED ultraviolet light source is an LED lamp panel, which is fixedly or detachably mounted on the housing, and the structure of the lamp panel is convenient for mounting and controlling.

The light emitting surface of the LED light source faces the groove, so that ultraviolet rays for sterilization are projected into the groove. In the ultraviolet LED light source, although the light source itself is defined as a cold light source, the LED chip itself generates heat during operation. Therefore, heat dissipation devices are required to be arranged on the LED chip and the light source, and the service life of the LED light source is determined by the strength of the heat dissipation capability. The structure of the heat sink of the LED light source is related to the structure of the LED chip and the design of the light source. In the present embodiment, the LED side plate is configured to radiate heat from the back side, that is, a heat radiating surface is provided on the back side of the light emitting surface. In the kitchen ware sterilization device, in order to improve the sterilization effect, an ultraviolet LED light source with higher power is required, so that the heating value is higher, and the heat dissipation requirement is higher.

In the prior art, in order to improve the drying effect of the kitchen ware, a heating device is usually arranged, and the kitchen ware is dried in an accelerating manner by generating heat through the heating device. This requires additional heating circuitry, which not only increases the complexity of the device but also increases the power consumption level of the device.

In the present embodiment, it is known from energy conservation that the refrigerator inevitably emits heat during cooling. For example, when the semiconductor refrigeration sheet is selected, the refrigeration sheet has a refrigeration end and a heat dissipation end, the refrigeration end is connected or adjacent to the heat dissipation surface of the LED light source, and the heat dissipation end dissipates heat outwards, in the embodiment shown in fig. 2, the heat dissipation surface is arranged downwards.

In this patent, in order to reduce kitchen utensils and appliances sterilizing equipment's power consumption to reduce its occupation space, the heat that gives off to the heat dissipation end of refrigerator is through retrieving hot-blast mode recycle, blows to the inslot that holds kitchen utensils and appliances with the higher hot-blast of temperature, thereby does not increase the energy consumption when improving the effect of drying to inslot kitchen utensils and appliances, and does not obviously increase the occupation volume of relevant device.

Specifically, the heat radiating end of the refrigerator may be disposed upstream of the air flow path by forming the air flow path, and the tub may be disposed downstream of the air flow path, so that heat from the heat radiating end of the refrigerator may be taken into the tub through the air flow to perform a drying operation on the kitchenware received in the tub.

For this purpose, the air inlet of the fan 3 may be fixed to the bottom of the housing, which may preferably be further opened with an opening for allowing external air to enter the housing. The LED lamp has the advantages of compact structure, no mutual interference among all functions, good LED light source heat dissipation effect and good drying effect.

In this embodiment, it is further preferable that a baffle 9 is further disposed on a side portion of the light emitting surface of the LED light source, the baffle is shaped as shown in fig. 2 and includes an inner side surface 11 inclined outward, and the baffle guides the wind blown by the fan into the groove on the one hand, and on the other hand, since the light emitting device and the heat generating device are actually integrated together in the embodiment, the baffle further preferably has a light guiding function, and the light emitted by the LED light source is projected to a larger range in the groove by disposing a reflective layer on an inner side wall of the baffle.

Further preferably, in this embodiment, the kitchen sterilization device is further provided with a control circuit board 7, wherein the control board and the main electronic device are both installed on the side board, and the control circuit board is connected with the LED light source, the fan and the refrigerator to control the operations of these components. Further preferably, in this embodiment, the top surface of the casing is provided with a protective cover, one end of the protective cover is hinged to the casing, a magnet is installed on the protective cover, the control circuit board is connected to the magnetic switch, when the protective cover is closed, the magnet on the protective cover excites the magnetic switch, a trigger signal of the magnetic switch is transmitted to the control circuit board to turn on the ultraviolet lamp, and once the protective cover is opened, the ultraviolet lamp is immediately turned off to prevent ultraviolet leakage.
