Abstract
The utility model relates to a protection structure of a pull-down door-opening type microwave oven. The protection structure comprises a door arm, a roller assembly and a spring, wherein the door arm is arranged on a roller of the roller assembly; one end of the door arm is connected with a microwave oven body, and a hook is arranged at the other end of the door arm; one end of the roller assembly is connected with the microwave oven body, and a hook is arranged at the other end of the roller assembly; the hook of the door arm is connected with the hook of the roller assembly through the spring; a mounting plate is arranged on the roller assembly and is positioned below the door arm; an interlock switch is mounted on the mounting plate; a wire harness of the interlock switch is connected with any pole of the input end of a microwave oven transformer; when the microwave oven body is closed, the door arm drives the interlock switch, so that the interlock switch is in a closed state; when the microwave oven body is opened, the door arm is separated from the interlock switch, so that the interlock switch is in an opened state. According to the protection structure of the pull-down door-opening type microwave oven, an accident caused by manual operation is avoided, so that the protection level of the microwave oven is improved.
Description
Technical field
The present invention relates to the open the door protection structure of micro-wave oven of a kind of pull-down, be specifically related to a kind of protection structure that prevents pull-down from opening the door micro-wave oven surprisingly opens.
Background technology
The protected mode of conventional microwave oven is commonly called as triple protection, i.e. induction, chain, monitoring, and door for microwave oven panel inner side is generally provided with three fine motion interlock switches.For side opening door type micro-wave oven, by gate stop, coordinate trace to drive interlock switch; For pull-down micro-wave oven, door body is provided with convex tendon and coordinates the connecting rod pilot hole on door face board to drive interlock switch.Micro-wave oven is put in the family, may occur that children play to it, if children use instrument or finger to inject the entrance of gate stop or connecting rod pilot hole, just likely can cause that three microswitches move simultaneously simultaneously, there is the unexpected generation such as micro-wave oven startup, electric shock.This shows, the triple protection that conventional microwave oven is commonly called as is also not perfectly safe, and to consumer, uses and has brought potential safety hazard.In prior art, for this potential safety hazard, there is no good solution simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of protection structure that prevents pull-down from opening the door micro-wave oven surprisingly opens.
For addressing the above problem, the protection structure that the utility model provides a kind of pull-down to open the door micro-wave oven, comprises an arm, roll wheel assembly and spring, and described door arm is placed on the roller of roll wheel assembly, and door 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, door arm hook is connected by spring between linking up with roll wheel assembly, it is characterized in that: described roll wheel assembly is provided with an installing plate, installing plate is positioned at an arm below, on described installing plate, interlock switch is housed, the wire harness of interlock switch is extremely connected with the arbitrary of micro-wave oven transformer input; When door for microwave oven body is closed, door arm drives interlock switch, makes interlock switch in closure state; When door for microwave oven body is opened, door arm separates with interlock switch, makes interlock switch in open mode.
Concrete, door arm rest door arm hook one end is provided with a limited block.
Concrete, on interlock switch, be connected with a fork.
Beneficial effect of the present invention is: a kind of pull-down that the utility model provides micro-wave oven safeguard structure that opens the door is an interlock switch dislocation box house in three interlock switches of door for microwave oven panel inner side by conventional mounting, and people is by finger or all cannot touch this interlock switch with instrument.Only have the door of working as by door arm, just can drive interlock switch to move in the situation of closing, avoided manual operation to meet accident.This protection structure has improved micro-wave oven degree of protection, and the safety problem while avoiding consumer to use micro-wave oven has solved a fly in the ointment of conventional microwave oven protected mode.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with regard to the specific embodiment of the present utility model, be described in further detail, wherein:
Fig. 1 is open the door each modular construction schematic diagram of protection structure of micro-wave oven of a kind of pull-down of the present invention;
Fig. 2 is that a kind of pull-down of the present invention opens the door the protection structure of micro-wave oven in the close the door schematic diagram of state of micro-wave oven;
Fig. 3 is a kind of pull-down of the present invention protection structure of micro-wave oven schematic diagram in microwave oven door-opening state that opens the door;
Fig. 4 is the open the door partial enlarged drawing of protection structure of micro-wave oven of a kind of pull-down of the present invention.
The specific embodiment
Shown in accompanying drawing 1-3, the present invention is the open the door protection structure of micro-wave oven of a kind of pull-down, comprises an arm 1, roll wheel assembly 2 and spring 3, and described door arm 1 is placed on the roller of roll wheel assembly 2, and door arm 1 one end is connected with door for microwave oven body, and the other end is provided with hook; Roll wheel assembly 2 one end are connected with door for microwave oven body, the other end is provided with hook, door arm 1 hook is connected by spring 3 between linking up with roll wheel assembly 2, described roll wheel assembly 2 is provided with an installing plate 4, installing plate 4 is positioned at an arm 1 below, on described installing plate 4, interlock switch 5 is housed, the wire harness of interlock switch 5 is extremely connected with the arbitrary of micro-wave oven transformer input; Door arm 1 is provided with a limited block 6 by door arm hook one end, is connected with a fork 7 on interlock switch 5.
When door for microwave oven body is closed, under the effect of spring 3, door arm 1 moves to interlock switch 5 tops backward with respect to door body, now the limited block 6 on door arm 1 promotes fork 7, fork 7 drives interlock switch 5, make interlock switch 5 in closure state, now transformer input conducting, can start micro-wave oven.When door for microwave oven body is opened, door arm 1 travels forward with door body, and limited block 6 separates with fork 7, and fork 7, not at compaction interlock switch 5, makes interlock switch 5 in open mode, and now the input of transformer cannot conducting.Even also cannot touch interlock switch 5 from the external world by connecting rod pilot hole, micro-wave oven cannot be opened.
The above; only for the better specific embodiment of the present invention, but protection domain of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore protection domain of the present invention is as the criterion with the protection domain of claims.
