Abstract
The invention discloses a ventilation structure of a microwave oven cavity, comprising a microwave oven cavity and a turntable arranged in the cavity. The bottom panel of the cavity is provided with an air inlet communicated with an electric control chamber from the outside of the cavity bottom, and the top panel of the cavity is provided with an air exhaust communicated with the outside of the microwave oven. The turntable is provided with a plurality of communicating holes. According to the invention, the original air inlet formed on the side of the cavity is plugged, and the intake from the cavity bottom is used as a replacement. Because the specific gravity of moist heat gas is light, food move to the top of the cavity when heating, the intake from the cavity bottom with the characteristics of large inlet air area and uniform passage in the cavity can take the moist heat gas away, in favor of heat dissipation of the cavity. Simultaneously, because of plugging the original air inlet, the flow around the fan is eliminated, so that the turbulent flow is reduced, and the noise is greatly reduced.

In the inside bottom surface of described cavity 12, have the pallet 14 that can support the container that food is housed, pallet 14 links with the motor (not shown) that produces revolving force and rotates, and evenly cooks the food that is positioned on the pallet 14 thus.
The place ahead of cavity 12 openings is provided with door 20.Door 20 is that benchmark is provided with rotationally with the hinge 22 that is positioned at one side top and the bottom, cavity 12 fronts, thus the front of shielding cavity 12 selectively.Door 20 has shielded after the cavity 12, and the microwave that is produced during micro-wave oven work just can not leak into the outside of described cavity 12.
Be provided with approximately in the back of door 20 and be
The door lock 24 of shape vertical section.Door lock 24 will be inserted into the door lock that is formed at cavity 12 fronts and insert 16 li in mouth.Door lock insert mouthfuls 16 be formed on door lock 24 corresponding positions on, have vertically long rectangular shape during from forward observation.
The rear side that inserts mouth 16 at door lock is equipped with micro switch (not shown).Micro switch (not shown) plays the effect that optionally makes lamp (not shown) energising, and door lock 24 is inserted into door lock and inserts 16 li in mouth, controls the power supply of turn-on lamp (not shown) by the interference of door lock 24 ends.Forwards rotary door 20 and with door lock 24 from door insert mouthfuls 16 draw after, the interference of 24 pairs of micro switch of door lock (not shown) can be removed, thus the power supply of turn-on lamp (not shown) and light lamp (not shown).
The right side of cavity 12 or upside have the control part 30 that comprises a plurality of action buttons 32 and display part 34.Control part 30 is connected with a plurality of parts that are installed in microwave oven electric control chamber 6 inside, controls micro-wave oven by controlling these parts thus.
As shown in Figure 2, existing furnace cavity structure is, wind is sucked into electric control chamber 6 from the air vent of back plate 1, through entering stove microwave oven cavity 12 by the air inlet (not shown) behind the fan, transformer and the magnetron that are positioned at electric control chamber 6, in cavity 12 hot and humid gas is taken away from steam vent 3 again.Therefore, there is following problem:
1, since the wind direction at air inlet place be not from the fan to the cavity 12 reaching the purpose of uniform flow field, but from cavity 12 to fan, so just near blade, form serious turbulent flow from the wind of the air vent suction of back plate 1 with fan, make the noise increase;
2, the wind that enters cavity 12 from air inlet causes cavity 12 top dewfall phenomenons serious because inlet and outlet position restriction can not be taken away all hot and humid gas in the cavity 12.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and can take away hot and humid gas to greatest extent, helps the cavity heat radiation, reduces the aeration structure of the microwave oven cavity of noise simultaneously.
The technical solution adopted in the present invention is: a kind of aeration structure of microwave oven cavity, include microwave oven cavity and be arranged at the rotating disk that is used for support food in the cavity, have the air inlet that is communicated with electric control chamber from the outside of cavity bottom on the bottom panel of described cavity, have exhaust outlet on the end face of described cavity with the micro-wave oven external communications.
Have most through holes on the described rotating disk that is used for support food.
The aeration structure of microwave oven cavity of the present invention, original air inlet that is formed on the cavity side is blocked up, change by the cavity bottom air intake, because the proportion of hot and humid gas is lighter, during heat food, can move to furnace chamber top, so from bottom air inlet, the bottom air inlet area is bigger on the one hand, the cavity inner flow passage is even on the other hand, can take away hot and humid gas to greatest extent, help the heat radiation of cavity.Simultaneously, owing to after blocking up original fresh air inlet upward, eliminated near the streaming of fan, thereby reduced turbulent flow, noise has obtained very big reduction.
