Description
Technical field
The utility model relates to a kind of micro-wave oven, particularly a kind of micro-wave oven interlocking switch device.
Background technology
Existing micro-wave oven interlocking switch device is shown in accompanying drawing 1-accompanying drawing 4, comprise support 21, be fixed on the gate stop 22 on the body, main interlocking switch 27, duplicate invoice lock-switch 25 and pilot switch 26, wherein main interlocking switch 27 and duplicate invoice lock-switch 25 are normal open switch, pilot switch 26 is a normally closed switch, and three switches are installed in respectively on support 21 relevant positions.Also be separately installed with the cam mechanism 28 of main interlocking switch 27 break-makes of control on the support 21, the cam mechanism 23 of control duplicate invoice lock-switch 25 break-makes and the cam mechanism 24 of control pilot switch 26 break-makes.
When using micro-wave oven closure fire door, the gib head 22.2 of gate stop 22 touches cam mechanism 24 earlier, and pilot switch 26 actions transfer off-state to by previous closure state; Then, the gib head 22.1 and 22.2 of gate stop touches cam mechanism 28 and cam mechanism 23 again, and main interlocking switch 27 and duplicate invoice lock-switch 25 transfer closure state to by off-state, and accompanying drawing 4 is seen in whole operating circuit conducting, and micro-wave oven is started working.When picking and placeing food, open fire door, because the above-mentioned cam mechanism of controlling three switches respectively is three mechanisms independently each other, have each other and delay, make can not the moving simultaneously of three switches: when pilot switch 26 returns to normal, (be closure state), main interlocking switch 27 and duplicate invoice lock-switch 25 also in action, are closure state, and this state causes short circuit, blowout especially easily.
In sum, the micro-wave oven interlocking switch apparatus structure complexity of this structure is provided with three cam mechanisms, parts are many, troublesome poeration, and security performance is poor.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and reasonable, flexible operation, effectively prevents short circuit and safe and reliable micro-wave oven interlocking switch device, to overcome weak point of the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of micro-wave oven interlocking switch device, comprise the gate stop that is arranged on the body, be arranged on main interlocking switch, duplicate invoice lock-switch and pilot switch on the furnace body support, main interlocking switch and duplicate invoice lock-switch are normal open switch, pilot switch is a normally closed switch, its architectural feature is that support is provided with cam mechanism, this cam mechanism comprises the cam that is hinged on the support, cam one end is connected with elastic reset spare, and the cam other end is arranged on the side or the end of gate stop slideway on the support.
Above-mentioned pilot switch is arranged on the cam top, and the duplicate invoice lock-switch is arranged on the cam below.
One end of the corresponding pilot switch of above-mentioned cam contact is provided with arc and presses the face that touches, and end was provided with flex point in face of this arc was pressed and touched.
The other end of the corresponding duplicate invoice lock-switch of above-mentioned cam contact is provided with crimping face, and this crimping face is hung on the top, contact.
Above-mentioned cam is curved or L shaped, and the middle part is provided with hinge hole, its our portion of opening gib head up or under gate stop.
When closing fire door, after the gib head of gate stop slipped over slideway, gate stop drove gib head and moves down under the spring action on the door body, gib head is pressed and to be touched the cam that joins with it or the contact on the switch: the following gib head of gate stop presses the cam in the cam mechanism, and then actuating cam rotates; In the cam rotation process, the arc of cam one end pressure is touched kept man of a noblewoman elder generation pressure and is touched the contact of pilot switch, and makes pilot switch enter off-state from normally off; Cam is rotated further then, and the crimping face pressure that is hung on the top, contact until the other end is touched on the contact of duplicate invoice lock-switch, and the duplicate invoice lock-switch enters closure state from normally open.Meanwhile, the last gib head of gate stop presses on the contact of main interlocking switch, and main interlocking switch enters closure state from normally open.Operating circuit is connected, and micro-wave oven is started working.
When opening fire door, the upper and lower gib head of gate stop moves on while retreating, cam is in the effect turning down of back-moving spring, disconnects respectively and the contacting of main interlocking switch and duplicate invoice lock-switch, and main interlocking switch and duplicate invoice lock-switch are by entering normally open from closure state; At this moment, the contact of pilot switch still presses the arc pressure of touching at cam to touch on the face, is in the relative time delay state, enters flex point position on the cam until the contact of pilot switch, and pilot switch enters normally off from off-state.Operating circuit blocks, and micro-wave oven quits work, and can effectively avoid circuit to be short-circuited, and burns out situation generations such as fuse.
The contact of pilot switch presses at arc that to touch the face slippage be delay time until the time that enters the flex point position in the utility model.
The utility model adopts a cam mechanism to substitute three cam mechanisms of the prior art, has reduced cost of manufacture.It is simple and reasonable, flexible operation, effectively prevent short circuit, and safe and reliable.
