Description
Technical field
The present invention relates to a kind of door gear of micro-wave oven.Furtherly, relate to a kind of button, can open the switching device of the door for microwave oven of door for microwave oven more accurately by door.
Background technology
Micro-wave oven is in heating clamber inside, by the device of microwave heating of food.But, if when the microwave of the inner heated food of heating clamber leaks toward the outside, can bring fatal influence to human body.So as shown in Figure 1, the door 2 of heating clamber is sealed during heating.
Consider the radiation of microwave, the structure of door 2 is designed to pin door with door bolt (diagram is omitted), make a structure that keeps closing state.So, in the micro-wave oven of state shown in Figure 1,, need the button 6 that is provided with by below control panel 4 in order to open door 2.That is, when pressing button 6, pin the door bolt of door and untied, door 2 is opened.
As shown in Figure 2, the back of control panel 4 be provided with untie door bolt untie parts 10, this unties parts 10 is that the center can rotate with hinge axis 16.And the bottom of control panel 4 is formed with a plurality of bullport 4a.Also have, the rear of button 6 forms the inner protruding end 6a that inserts of a plurality of oriented bullport 4a.
As shown in Figure 3, Figure 4, protruding end 6a is the bullport 4a that runs through control panel 4, and can promote to untie parts 10.And, be positioned at button 6 centers protruding end 6a around, being inserted with can be the button 6 spring s of resiliency supported forwards.
When rearward pressing button 6, the rearward end of protruding end 6a rearward moves, and promotes the bottom 12 of untiing parts 10.At this moment, be center rotation with hinge axis 16 when untiing parts 10, a side of untiing parts 10 protrude form separate the beginning 14 also thereupon rotation separate the latch that opens the door, door 2 is opened.
According to the prior art with spline structure, button 6 is forwards rebounded by spring s after rearward squeezing and opening once more.But embodiment as shown in Figure 3, Figure 4 when at the center spring s only being set, produces the situation that protruding end 6a is buckled in smooth and easy motion forwards among the bullport 4a.Particularly, when pressing the side, both sides of button 6, this phenomenon takes place frequently.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of at the breakdown action that can make door simultaneously smoothly, can carry out the switching device of the door for microwave oven of on-off action repeatedly.
The technical solution adopted in the present invention is: a kind of switching device of door for microwave oven, include in the bottom of the control panel of door for microwave oven side and rearward protrude the mounting groove of formation, the button that is provided with on the mounting groove, integrally formed most the protruding end of rearward protruding at the back side of button, the protruding end makes the parts action of opening door when rearward mobile, the bottom of mounting groove is formed with corresponding with the protruding end, and most the bullports that the protruding end is connected, in the two sides of mounting groove to the direction of button, prolong according to certain gradient, and a pair of elasticity muscle that leading section supports simultaneously on the face of the left and right sides of button.The elasticity muscle be arranged on antarafacial with button on corresponding position for well.And the elasticity muscle is contacted with the back side of button on the outer peripheral face of the outermost protruding end of most protruding ends.
According to aforesaid the present invention, under the effect of the symmetrically arranged a pair of elasticity muscle of the antarafacial of button, the same elasticity forwards of the left and right sides part of button is outstanding.So the anticipation effect of the global reliability that improves button actions is arranged.

The specific embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify the present invention and how to realize.
Fig. 5 is corresponding to Fig. 4, represents the schematic cross-sectional view that concerns between button of the present invention and the control panel.
As shown in Figure 5, bottom one side at the control panel 30 of micro-wave oven is provided with button 20.That is, control panel 30 rearward protrudes and is formed with mounting groove 34, and button 20 is arranged on the inside that control panel 30 rearward protrudes the mounting groove 34 that forms, and can forwards move at certain intervals.And the back side of button 20 is formed with most protruding ends 22.On the corresponding position in mounting groove 34 bottoms of control panel 30 and protruding end 22, be formed with the bullport 32 that is come in and gone out in protruding end 22 of through hole.And, be formed with a pair of elasticity muscle 40a, the 40b that protrudes to button 20 directions in the inside of mounting groove 34.
Elasticity muscle 40a, 40b are that the back from mounting groove 34 tiltedly prolongs to button 20 square necks, and its leading section is supported by the outermost surface of most protruding ends 22 on the button 20.Elastic rod muscle 40a, 40b are to be that button 20 provides elastic restoring force with what have that certain flexible material makes.And, elasticity muscle 40a, 40b is arranged on symmetrical position, button 20 both sides on.
So, when pressing button 20, even by toward the position of lopsidedness, also can by a pair of elasticity muscle 40a, 40b with button 20 all forwards elasticity rebound.
Below, the action of the button of the present invention 20 of structure describes to having as above.
The user will rearward press button 20 in order to open the door of micro-wave oven.When the mounting groove 34 that is provided with a pair of elasticity muscle 40a, 40b to inside was pressed button 20, a pair of elasticity muscle 40a, 40b be the elasticity modification rearward, and button 20 is rearward compressed into thereupon.
Rearward move the protruding end 22 that the antarafacial of button 20 forms, and connects bullport 32, touches the parts (untiing latch) that are used to open door for microwave oven, is untied the closed condition of door for microwave oven by the latch that touch protruding end 22, so that open door.
Open micro-wave oven behind the door by the process of the above, the user decontrols button 20, and at this moment, button 20 is supported by both side ends, and by a pair of elasticity muscle 40a, 40b forwards elasticity bounce back into original position.That is, according to the present invention, a pair of elasticity muscle 40a, 40b that button 20 is set at its antarafacial bounce back into original position with the same elasticity forwards in the left and right sides.
The present invention is arranged on the antarafacial of button 20, simultaneously a pair of elasticity muscle 40a, the 40b of the antarafacial both sides of resiliency supported button 20, and give the structure of the same elastic force of button about 20 simultaneously.
In aforesaid basic fundamental of the present invention field, the people with common knowledge has many other modification.These should rely on the claim item that adds with the present invention and explain.
