The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 4 is the example structure plane of the interlock of door for microwave oven of the present invention.Fig. 5 is the working state figure of the embodiment of the invention course of work.
As shown in the figure, door 6 is used to open and close the cooking room of inside cavity, is provided with door bolt 7 at the back side of door 6.Door bolt 7 is generally supporting by elastomeric element, can carry out lifting along direction as shown in Figure 4.The top and bottom of door bolt 7 form towards the rear of door 6 is outstanding respectively, are formed with first pressing face 54 and second pressing face 56 respectively on the front end of the door bolt 7 that downward distal process goes out.First pressing face 54 and second pressing face 56 have certain area respectively, and can be by button 81 below.The angle that the elongated surfaces of first pressing face 54 and second pressing face 56 intersects is more a little bit smaller than the right angle.In addition, blocking surface 57 is arranged on door bolt 7, blocking surface 57 is positioned on the position opposite with first pressing face 54.Blocking surface 57 tilts towards the forward lower part of door bolt 7.
On a side of the front panel 4 of cavity front door bolt groove 5 is arranged, door bolt groove 5 is used for door bolt 7 and comes in and goes out.Door bolt groove 5 is formed on the position corresponding to door bolt 7, and the number of door bolt groove 5 is corresponding to the number of door bolt 7.
The back side of front panel 4 is provided with door bolt plate 20.As shown in Figure 4, door bolt plate 20 forms along prolonging up and down, is installed in the back side of front panel 4.On the position corresponding to the door bolt plate 20 of door bolt groove 5 guide pass 72 is arranged, the inboard front end of guide pass 72 is provided with and stops holder 74, stops that holder 74 is used to be stuck in the blocking surface 57 of door bolt 7.
Be provided with monitor switch 32 in the inboard of the guide pass 72 of door bolt plate 20 lower ends in addition.Wherein the button 81 of monitor switch 32 is positioned on the position apart from guide pass 72 direction of advance certain distances.That is to say that when being arranged on monitor switch 32 on the door bolt plate 20, button 81 will be towards guide pass 72.
On the top and bottom of door bolt plate 20, be respectively arranged with interlocking switch 30.Wherein, the button 81 that is arranged on the interlocking switch 30 of lower end is positioned at distance and stops the position of holding in the palm 74 specific ranges, that is to say, button 81 is positioned at the position of distance cardinal principle perpendicular to the side's of advancing specific range of guide pass 72.
Wherein, be slightly less than 90 degree towards the extended line of button 81 projected directions of monitor switch 32 with towards the angle that the button 81 outstanding direction extended lines of interlocking switch 30 form.In the time of in door bolt 7 is inserted into door bolt groove 5, each extended line is respectively preferably respectively perpendicular to first pressing face 54 and second pressing face 56.
Effect to the interlock of door for microwave oven of the present invention with said structure describes below.
In micro-wave oven, door 6 is covering outer and cooking room optionally, and in the cooking, the microwave that prevents cooking room inside is to external leaks.For this reason, when closing door 6 the time, the blocking surface 57 of door bolt 7 will be stuck in and stop in the holder 74.At this moment,, press blocking surface 57 towards the below, door 6 is not opened by being arranged on the elastic force that elastomeric element provided of door bolt 7 of door 6 inside.
To closing door 6, the process of pressing the button 81 of monitor switch 32 and interlocking switch 30 describes below.
If close door 6, door 6 will be combined closely in front on the plate 4.The upper and lower side of giving prominence at the door bolt 7 at door 6 back sides inserts towards the rear of front panel 4 by door bolt groove 5 respectively.
As shown in Figure 4, along with the front end of guide pass 72 guiding door latches 7.Because towards upper angled, the elastic force that makes door bolt 7 overcome elastomeric element moves to top guide pass 72 from the bottom of door bolt plate 20.
In addition, the front end of door bolt 7 that is to say, if second pressing face 56 has passed through the end of guide pass 72, by the restoring force of elastomeric element, door bolt 7 is moved towards the bottom, makes the blocking surface 57 of door bolt 7 be stuck in and stops in the holder 74.
Meanwhile, first pressing face 54 of door bolt 7 and second pressing face 56 are pressed the button 81 of monitor switch 32 and interlocking switch 30 respectively.As shown in Figure 5, monitor switch 32 and interlocking switch 30 are driven, and perceive the closed condition of door 6.
When opening door 6 the time, open door 6 strength by the user, make door bolt 7 overcome the elastic force of elastomeric element, make blocking surface 57 from stopping in the holder 74.In addition, along with the front end of guide pass 72 guiding door latches 7, the front end of door bolt 7 is broken away to the outside of front panel 4.By said structure, door 6 breaks away from front panel 4 and is opened, and will no longer press on the button 81 of monitor switch 32 and interlocking switch 30.
