Description

Disinfection cabinet

Technical Field

The invention relates to the technical field of kitchen equipment, in particular to a disinfection cabinet.

Background

Most of disinfection cabinets in the market at present are disinfected by high temperature or ozone, occasional ultraviolet disinfection cabinets are combined with high temperature or ozone, and few independent ultraviolet disinfection cabinets exist, because the disinfection range of ultraviolet illumination disinfection in the cabinet body is limited, so that incomplete disinfection is easily caused, and certain defects exist.

In order to solve the above problems, the invention patent with patent application number CN201710355512.3 (publication number CN107961386A) discloses a disinfection cabinet, which comprises an inner container, wherein an ultraviolet lamp tube and a reflector are arranged in the inner container. The reflector can collect and reflect the ultraviolet light beams emitted by the ultraviolet lamp tube, so that the illumination intensity of the ultraviolet light is enhanced.

In addition, for the disinfection lamp tube, a quartz glass tube cover is generally required to be sleeved on the periphery of the disinfection lamp tube, so that the disinfection lamp tube is protected, and a user is prevented from colliding with the disinfection lamp tube when taking and placing tableware. However, on the one hand, the sterilizing light loses a part of energy when penetrating through the quartz glass, and on the other hand, the heat dissipation of the sterilizing lamp tube is hindered, and the service life is reduced.

Disclosure of Invention

The first technical problem to be solved by the invention is to provide a disinfection cabinet which can reflect light and protect a disinfection lamp tube by a set of device aiming at the current situation of the prior art.

The second technical problem to be solved by the invention is to provide a disinfection cabinet which reflects disinfection light when a drawer is closed and protects a disinfection lamp tube when the drawer is opened.

The third technical problem to be solved by the invention is to provide a disinfection cabinet with high disinfection efficiency and good disinfection effect.

The technical scheme adopted by the invention for solving the first technical problem is as follows: a disinfection cabinet, which comprises

A cabinet body having a sterilization chamber;

at least one drawer capable of being drawn in and out of the disinfection chamber; and

the disinfection lamp tube is arranged on the inner wall of the cabinet body;

the method is characterized in that: also comprises

The reflecting protective cover is arranged around the periphery of the disinfection lamp tube, an opening extending along the length direction of the disinfection lamp tube is arranged on the peripheral wall, and the reflecting protective cover can rotate around the disinfection lamp tube and at least has two states:

in the second state, the opening of the reflective protective cover faces the wall surface where the disinfection lamp tube is installed, and the disinfection lamp tube is shielded by the reflective protective cover.

In order to further solve the second technical problem, the disinfection cabinet further comprises

The transmission assembly is arranged between the drawer and the reflective protective cover and can transmit the action of the drawer to the reflective protective cover so as to drive the reflective protective cover to be converted into a first state or a second state in the closing or opening process of the drawer.

In order to transmit the action of the drawer to the reflective protection cover, there are roughly two schemes:

the first scheme is that a plurality of drawers correspond to a reflective protective cover, and the transmission assembly comprises

The base is fixed relative to the cabinet body;

the rotating shaft penetrates through the base and extends along the height direction of the cabinet body;

when one of the drawers is opened, the corresponding door control switch controls the electromagnet to be electrified;

and under the other open state of the drawer, the corresponding door control switch controls the electromagnet to be powered off.

In order to limit the descending position of the rotating shaft by using gravity when the power is off, the driving device also comprises

The limiting piece is fixed relative to the cabinet body and is positioned below the electromagnet;

In order to realize multi-angle diffuse reflection of the disinfection light and avoid light intensity dead angles, a plurality of bosses or grooves which are arranged at intervals are formed on the inner wall of the light-reflecting protective cover.

In order to facilitate the processing of the boss, the boss is formed by locally pressing the peripheral wall of the reflective protective cover inwards.

In order to ensure the multi-angle reflection effect, the outer circumference of the cross section of the boss is gradually reduced from the inner wall of the light reflection shield to the end part of the boss.
