Description
Technical field
The utility model relates to door lock mechanism, especially relates to a kind of safety door latch mechanism preventing steam and microwave leakage.
Background technology
In the kitchen appliances such as existing micro-wave oven, electric steam box and electric oven, be generally all designed to the door-opening mode of sliding door type, for this door-opening mode, all there is corresponding gate interlock structure.The cabinet front plate that the gate interlock structure of existing routine generally comprises a body and coordinates with door body, door body is provided with gate stop, cabinet front plate is installed gate interlock support, gate interlock support is installed the microswitch triggered by gate stop.
If the patent No. is " a kind of gate interlock structure " disclosed in the Chinese utility model patent of ZL 201420477422.3 (Authorization Notice No. is CN 204060197 U), this gate interlock structure installs gate stop support on door body, gate stop is arranged on gate stop support rotationally, gate interlock support is provided with the moving block that can trigger microswitch, be provided with between gate stop support and gate stop can oppress gate stop and and then moving block is had continue to trigger the first elastic component of microswitch trend, gate interlock support is also provided with and makes the moving block triggering microswitch have the trend of rotating backward and depart from the second elastic component of microswitch.The advantage of this gate interlock structure is that the first elastic component can be oppressed gate stop and be made moving block trigger microswitch at closing time, door body can not be opened easily, security is high, in addition, under the effect of the second elastic component, door body is subject to the opposition of moving block at closing time, and during enabling, door body is subject to the thrust of moving block, opens the door and closes the door and be more comfortable.But after adopting elastic component, the comparatively complexity of the structure of this gate interlock, manufacturing cost is higher.
And for example the patent No. is " universal oven port interlocking mechanism for microwave oven " disclosed in the Chinese utility model patent of ZL 201020545967.5 (Authorization Notice No. is CN 201925981 U), this interlocking mechanism comprises switch base, gate stop and header board, switch base can place multiple switch, the position of corresponding each switch is provided with the action key of this switch of operation, on the fire door that gate stop is located at micro-wave oven and opening with fire door, this switch base of Guan Eryu combines or departs from, this gate stop has at least one hook portion, for triggering these switches by touching these action keys, header board is for being fixed on the cavity of micro-wave oven by switch base.Because this door interlocking mechanism is all located at gate stop for two hook portions touching microswitch action key, header board is formed the recess stretched into for gate stop, if so with the round shape object of little iron wire and so on, push down two recesses because of carelessness simultaneously, under micro-wave oven starting state, likely cause microwave error starting under door opening state, thus bring potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, provides the safety door latch mechanism preventing steam and microwave leakage that a kind of compact conformation is succinct, security is high.
