Following facts and the discovery of problem and understanding are made by the application based on inventor:
The microwave cooking devices such as such as drawer-type microwave oven, during work, electrical part can produce substantial amounts of heat, needs to arrange
Electrical part is cooled down by air channel.In prior art, functional electrical part such as fan component, magnetron, transformator is installed
At culinary art cavity rear, cooling air channel is also arranged on cooking cavity rear.
Owing to drawer-type microwave oven is typically mounted in cabinet, and embedded product typically requires because of safety requirement, outer housing
Airtight, therefore air outlet typically can only be located at culinary art cavity front, and so, electrical part is located at cooks cavity rear, and air outlet
Being located at culinary art cavity front, the air channel causing hot blast is longer, hot blast can after drawer type microwave furnace interior is detained longer time,
Just discharge from air outlet, and hot blast be detained during this period of time in, heat can be absorbed again again, thus reduces whole drawer
The heat dispersion of type micro-wave stove, have impact on the service life of drawer-type microwave oven.
To this end, the present invention proposes the drawer-type microwave oven 1 of a kind of perfect heat-dissipating, length in service life.
Below with reference to Fig. 1-Fig. 6, drawer-type microwave oven 1 according to embodiments of the present invention is described.

Pipe 360, transformator 330 is located in the first air-out passage 10, and magnetron 360 is located in the second air-out passage 20.Drawer 400 can push away
It is arranged on drawing at least one in shell 100 and culinary art cavity 200, to open and close cooking chamber, here, drawer 400
May be mounted on shell 100 or culinary art cavity 200, or, drawer 400 can be separately mounted to shell 100 and culinary art cavity
On 200.
Drawer-type microwave oven 1 according to embodiments of the present invention, by being located at the antetheca of culinary art cavity 200 by air outlet 201
Top, and vortex fan 500 and electrical part 300 are arranged on the outer top wall surface of culinary art cavity 200, and transformator 330 set
In the first air-out passage 10, magnetron 360 is located in the second air-out passage 20, and so, electrical part 300 is arranged in neighbouring air-out
The position of mouth 201, is discharged by air outlet 201 after the air cooling transformator 330 that the first air outlet 503 flows through, send from second
After the air cooling magnetron 360 that air port 504 is flow through enter cooking chamber, take away culinary art produce oil smoke and water vapour, then from
Air outlet 201 is discharged, thus shortens the flow path of hot blast, accelerates the rate of cooling to electrical part 300, improves heat radiation
Performance, extends the service life of drawer-type microwave oven 1.
According to some embodiments of the present invention, as Figure 4-Figure 6, air channel also includes bottom air inlet passage 31, sidepiece wind
Road 32, air channel, rear portion 33 and air-suction channel 34.Bottom air inlet passage 31 is positioned at the lower section of cooking chamber, and 31 points of bottom air inlet passage
Do not connect with air inlet 202, sidepiece air channel 32 and air channel, rear portion 33.Sidepiece air channel 32 is positioned at the sidepiece of cooking chamber, and sidepiece wind
Road 32 connects with air-suction channel 34.Air channel, rear portion 33 is positioned at the rear portion of cooking chamber, and air channel, rear portion 33 connects with air-suction channel 34,
Vortex fan is positioned at air-suction channel 34.
Thus, vortex fan 500 is by air from the suction air channel, bottom of the antetheca of culinary art cavity 200, and air respectively flows through
The lower section of cooking chamber, the sidepiece of cooking chamber and the rear of cooking chamber also enter vortex fan 500, and then, portion of air is from
One air outlet 503 flows through the top of cooking chamber, cools down transformator 330, then discharges from air outlet 201, and another part air is from the
Two air outlets 504 flow through the top of cooking chamber and cool down magnetron 360, enter back into cooking chamber, finally discharge from air outlet 201.
Alternatively, as shown in Fig. 2, Fig. 4 and Fig. 5, vortex fan 500 has the first inlet scoop 501 and the second inlet scoop
502, the first inlet scoop 501 connects with the first air outlet 503 and air channel, rear portion 33 respectively, and the second inlet scoop 502 is respectively with second
Air outlet 504 connects with sidepiece air channel 32.
Thus, the cold wind flowing into air-suction channel 34 respectively from sidepiece air channel 32 and air channel, rear portion 33 is divided into two-way, the first via
Cold wind is entered the first air-out passage 10 by the first air outlet 503 and cools down transformator 330, then discharges drawer from air outlet 201
Type micro-wave stove 1, the second road cold wind is entered the second air-out passage 20 by the second air outlet 504, enters culinary art after cooling magnetron 360
The oil smoke in cooking chamber and water vapour are also taken away in room, are then discharged out cooking chamber, are finally discharged drawer-type microwave oven by air outlet 201
1。
In some specific embodiments of the present invention, as shown in Figure 2 and Figure 5, electrical part 300 also includes computer board assembly
310, filter band 320, high-voltage capacitance 340 and stirring motor 350, computer board assembly 310 is located in air-suction channel 34, and computer board
Assembly 310 is arranged adjacent to the second inlet scoop 502, and filter band 320 is located in air-suction channel 34, and filter band 320 is inhaled adjacent to first
