Chinese patent 201420150578.0 discloses a kind of operator guards of pull-down enabling micro-wave oven, and comprise gate arm, roll wheel assembly and spring, described gate arm is placed on the roller of roll wheel assembly, and gate arm one end is connected with door for microwave oven body, and the other end is provided with hook; Roll wheel assembly one end is connected with door for microwave oven body, the other end is provided with hook, be connected by spring between gate arm hook with roll wheel assembly hook, described roll wheel assembly is provided with an installing plate, installing plate is positioned at below gate arm, described installing plate is equipped with interlock switch, and the wire harness of interlock switch is extremely connected with the arbitrary of micro-wave oven transformer input; When door for microwave oven body closes, gate arm drives interlock switch, makes interlock switch be in closure state; When door for microwave oven body is opened, gate arm is separated with interlock switch, makes interlock switch be in open mode.This utility model avoids manual operation and meets accident, and improves the degree of protection of micro-wave oven.But this utility model is only applicable to the protection of pull-down enabling micro-wave oven, and be not suitable for the protection of side-pull type enabling micro-wave oven.
Utility model content
The purpose of this utility model is the protective device providing a kind of side-pull type enabling micro-wave oven, avoids manual operation side-pull type enabling micro-wave oven and meets accident, improve the degree of protection of micro-wave oven.
For achieving the above object, the utility model is by the following technical solutions:
A protective device for side-pull type enabling micro-wave oven, comprises fine motion interlock switch, also comprises support plate, turning cylinder and turning joint, and described fine motion interlock switch is arranged on below door for microwave oven body, and described fine motion interlock switch and described support plate form interlock and coordinate; The wire harness of described fine motion interlock switch is connected with micro-wave oven computer board controller; Described support plate one end is provided with described turning cylinder, and the described support plate other end is connected with micro-wave oven front panel, base plate respectively; Described turning joint is arranged on described door for microwave oven body, and described turning joint lower end is provided with installing plate, and described installing plate is connected with described turning cylinder; When door for microwave oven body closes, described support plate drives described fine motion interlock switch, makes fine motion interlock switch be in closure state; When door for microwave oven body is opened, described support plate separates with fine motion interlock switch, makes interlock switch be in open mode.
As further preferred embodiment of the present utility model, described support plate is provided with limited block near described turning cylinder one end.Limited block can limit turning joint and rotate, and keeps oven door opening angle to remain on certain limit.
The beneficial effects of the utility model: the protective device of a kind of side-pull type enabling micro-wave oven that the utility model provides is by inner for a fine motion interlock switch dislocation fire door in three fine motion interlock switches of conventional mounting inside side-pull type enabling door for microwave oven panel, people is by finger or all cannot touch this fine motion interlock switch with instrument, only have dynamic interlock switch ability action under door is in a closedown situation, avoiding manual operation meets accident; This protective device improves side-pull type enabling micro-wave oven degree of protection, and safety problem when avoiding consumer to use side-pull type enabling micro-wave oven, solves a fly in the ointment of conventional microwave oven protected mode.
