Disinfection cabinet with thermo-drive overlap lock and other household electrical appliance

Abstract

A disinfection cabinet which lock are driven up by heating power and other household electrical appliance, said heating power driving lock device uses the element of bimetal films temperature distortion, controls the switch of door through simple mechanical gearing, when the temperature of bimetal films reaches a certain level, the bimetal films occur deformation to starting lock device and locking the door; when the temperature decreases certain level, the door is released. The structure of said device in the invention is simple and easy to install; power consumption is small, power is low; use is safe and reliable during work process; the invention need not artificial unlock and lock, it controls the switch of heating power driving lock through signals of computer control panel and perimeter temperature of bimetal films.

Description

technical field [0001] The invention relates to a disinfection cabinet and other household electrical appliances adopting heat-driven snap-on. Background technique [0002] National Standard GB17988-2004 of the People's Republic of China "Safety and Sanitation Requirements for Tableware Disinfection Cabinets" stipulates in 6.1.22.101 that "ozone disinfection cabinets (rooms) and ultraviolet disinfection cabinets (rooms) should be equipped with door switches. When the maximum gap opened is greater than 2cm, the ozone generator and ultraviolet lamp stop working immediately, and the ozone generator and ultraviolet lamp can be restarted when the door is closed again. Ozone concentration ≥ 40mg / m 3 The door of the ozone disinfection cabinet (room) and ultraviolet disinfection cabinet (room) should be equipped with a brake lock switch, so that the door of the disinfection cabinet (room) can only be opened after the disinfection cabinet (room) completes the disinfection cycle. [...

AI Technical Summary

Problems solved by technology

[0003] The two states given by this standard may cause harm to the human body if the locks of the prior art are used in specific implementation:

[0004] The first is to open the door and cut off the power so that the ozone generator and the ultraviolet lamp stop working. However, if the ozone concentration in the ozone disinfection cabinet (room) and ultraviolet disinfection cabinet (room) is still above the dangerous concentration when the door is opened, it will Injury to the human body occurs;

[0005] The second is to refuse to open the door without completing the work cycle, which actually specifies that only electronic locks can be used, because only electronic locks can communicate with the control devices of the ozone disinfection cabinet (room) and ultraviolet disinfection cabinet (room). linkage

[0008] Most of the existing disinfection cabinet (or similar electrical appliances) door switches are contact power-off type. The contact power-off type can be easily opened during high-temperature disinfection or ozone disinfection. Although the disinfection cabinet and other household appliances The electrical components will stop working, but the high temperature and (or) a large amount of ozone generated during the period will not decrease and (or) disappear instantly. At this time, it is very easy to cause high temperature burns to the human body and (or) high concentration ozone leakage to the human body.
