Description
Technical field
The present invention relates to field of mechanical technique, particularly relate to a kind of built-in microwave oven.
Background technology
Micro-wave oven is to produce microwave by electric current, and microwave irradiation surface of heating object in the cavity is come device that article are heated.As everyone knows, micro-wave oven is a kind of modernization cooking kitchen range with microwave heating of food.The microwave that it adopted is a kind of electromagnetic wave.This electromagnetic energy is not only much bigger than common radio wave, but also characteristics are arranged very much, and microwave at a touch metal just reflects, and metal has no idea to absorb or conduct it at all; Microwave can pass insulating materials such as glass, pottery, plastics, but can consumed energy; And contain the food of moisture, and microwave not only can not see through, and its energy can be absorbed on the contrary.Based on these characteristics, micro-wave oven is heat food well, has obtained utilization widely in daily life.
Along with development of times, rise day by day kitchen articles such as gas furnace or kraut refrigerator are designed to damascene structures, make between household appliances and the kitchen furniture and coordinate mutually, give whole aesthetic feeling.Micro-wave oven also just is designed to embedded, i.e. built-in microwave oven.
Referring to Fig. 1, Fig. 2, existing a kind of built-in microwave oven includes housing 1, is positioned at the front panel 4 in housing 1 front, door for microwave oven 5 and escutcheon 6, control panel 10, in housing 1, be formed with culinary art cavity 2 and electric apparatus room 3, described culinary art cavity 2 is positioned at the left side of housing, the right side of housing 1 is described electric apparatus room, magnetron 7, high-tension transformer 8 and high-voltage capacitor are installed in this electric apparatus room, and the periphery of described escutcheon 6 is designed to the rectangle sheet frame.
In the lump referring to Fig. 3, the periphery upper side of described escutcheon 6 is provided with air inlet 61, on described housing 1 rear board, have air outlet 62, after the air of micro-wave oven outside enters from the air inlet 61 of escutcheon 6 upper sides, to carrying out radiating and cooling in the micro-wave oven, form hot-air at last and emit from the air outlet 62 on housing 1 rear board.
But, when being placed in the cabinet in view of built-in microwave oven, the rear board of housing 1 is towards the inner space of cabinet, so the hot-air that the air outlet 62 from housing 1 rear board comes out discharges towards cabinet inside, and cabinet is generally the structure of inner sealing, sluggish in air circulation, therefore the hot-air that comes out from air outlet 62 makes the air themperature of cabinet inside constantly rise easily, can't well be dispelled the heat, thereby formation disaster hidden-trouble, and when micro-wave oven catches fire because of breaking down, flame comes out along air outlet 62, direct and cabinet inner surface comes in contact burning, and the user who is positioned at housing 1 the place ahead can't in time find flame, causes the generation of fire.
In addition, under the long-term exhaust of hot air of air outlet 62 is impacted, the easy temperature distortion of the inner surface of cabinet, the coating of inner surface etc. comes off easily, therefore cabinet is caused damage.
