The specific embodiment
Below, with reference to Fig. 3 and Fig. 4 the micro-wave oven according to the embodiment of the invention is specifically described.
At first, Fig. 3 shows is internal structure according to the micro-wave oven of the 1st embodiment of the present invention.
That is, the micro-wave oven according to the 1st embodiment of the present invention is to be made of following components substantially: cavity 100; Shell 200; Electronic component; Vibrationproof portion.
Here, above-mentioned cavity 100 forms the culinary art chamber, and constitutes the main body of micro-wave oven.The shape of cavity 10 of micro-wave oven that the shape of above-mentioned cavity 100 and electricity storage chamber in the past are positioned at upside is identical.
In addition, above-mentioned shell 200 constitutes the outward appearance of micro-wave oven, and forms around above-mentioned cavity, and is formed with electricity storage chamber at the upper space of above-mentioned cavity 100.
In addition, above-mentioned electronic component comprises magnetron 310 and high voltage transformer 320.Above-mentioned magnetron 310 and high voltage transformer 320 be installed on respectively above-mentioned cavity 100 above.
At this moment, above-mentioned high voltage transformer 320 is positioned at the rear side of electricity storage chamber with respect to above-mentioned magnetron 310.
In addition, the position that emits microwave in the above-mentioned magnetron 310 possesses waveguide pipe 311 is arranged, and the effect of above-mentioned waveguide pipe 311 is: above-mentioned microwave is provided to the culinary art chamber interior.
In addition, above-mentioned vibrationproof portion is arranged between the top and above-mentioned shell 200 of above-mentioned high voltage transformer 320.The effect of above-mentioned vibrationproof portion is: prevent that the vibration that produces in the above-mentioned high voltage transformer 320 is delivered in the above-mentioned shell 200.
Above-mentioned vibrationproof portion is made of vibrationproof member 410 and Support bracket 420.
Above-mentioned vibrationproof member 410 be with rubber etc. can sound-absorbing and the material that reduces to vibrate make, and be close to the upper central position of being fixed in high voltage transformer 320.
In addition, above-mentioned Support bracket 420 is to make with solid materials such as metal material or plastic materials, and is the center with the position at above-mentioned vibrationproof member 410 places, and an end is fixed in the top rear side of above-mentioned shell 200, and the other end is fixed in magnetron 310.
At this moment, above-mentioned Support bracket 420 constitutes the plane with the position that above-mentioned vibrationproof member 410 is close to, two lateral end of above-mentioned Support bracket, and formation gradually is inclined upwardly.
This is for above-mentioned Support bracket 420 is close on the above-mentioned vibrationproof member 410 fully.
Therefore, even, also can utilize vibrationproof member 410 to make vibration attenuation, can prevent that therefore vibration is delivered in the shell 200 because the operation of high voltage transformer 320 produces vibration.
But in the aforesaid structure according to the 1st embodiment of the present invention, if the vibration of high voltage transformer 320 is bigger, Support bracket 420 itself can produce vibration.
