Description
Technical field
The present invention relates to a kind of micro-wave oven.Particularly relate to a kind of by a cooling fan, the ventilation hood type microwave furnace of the fire door of cooled microwave stove being set in inside, distribution chamber.
Background technology
Micro-wave oven on the market has varied now.Micro-wave oven normally is placed on the desktop and uses.But in the micro-wave oven that occurs, the ventilation hood type microwave furnace that possesses fume exhausting function is arranged recently.This micro-wave oven is positioned at the top of culinary art facility, such as the top of gas furnace etc., in order to discharge oil smoke and the heat that they produce.Fig. 1 is the mobile state side section schematic diagram of the ventilation hood type microwave furnace inner air of conventional art.
As shown in Figure 1, in the ventilation hood type microwave furnace, cavity combining body 10 forms framework.Positive upper end at cavity combining body 10 has ventilation grill 15, and ventilation grill 15 plays the ventilation channel effect of air.In addition, a side of micro-wave oven possesses distribution chamber 20.
In the distribution chamber 20, be provided with as various electronic units such as magnetrons 21.In addition, the side in distribution chamber 20 forms air inflow aperture 11a, is communicated with cooking cavity (figure slightly).Cooking cavity is the space that is used to cook.Distribution chamber 20 also possesses cooling fan 23,25.Cooling fan 23,25 is made up of the 1st cooling fan 23 and the 2nd cooling fan 25.The 1st cooling fan 23 is located at the rear end, top in distribution chamber 20.The 2nd cooling fan 25 is located at the lower end, the back side in distribution chamber 20.
Possess 20 back sides, distribution chamber of the 2nd cooling fan 25 and form between the backboard 17 of micro-wave oven back appearance, press above-below direction formation path 19.The oil smoke that produces in the time of can discharging the culinary art of culinary art machine such as gas furnace by path 19.The inside in distribution chamber 20 is provided with draft fan assembly (figure slightly).Under the effect of draft fan assembly, flow air in path 19 is discharged from by ventilation grill 15.
Under the conventional art, in the ventilation hood type microwave furnace, the air flow condition to inside, distribution chamber is described as follows.
At first, under the effect of the 1st cooling fan 23,, flow to the air of micro-wave oven inside, flow to distribution chamber 20 by ventilation grill 15.Flow to the air of 20 inside, distribution chamber, under the effect of the 1st cooling fan 23 and the 2nd cooling fan 25, circulation distribution chamber 20, cooling comprises the various electronic units of magnetron 21.
Behind the cooling electronic components, part of air is by air inflow aperture 11a, to the cooking cavity internal flow.After entering cooking cavity inside, air can absorb the steam of cooking cavity inside, and under the effect of the 1st cooling fan 23 and the 2nd cooling fan 25, the flow export (figure slightly) by the cooking cavity end face outwards flows out.
But there are the following problems to possess the tradition ventilation cover type micro-wave oven of said structure.
When cooking, in cooking cavity, produce a lot of heats, so the temperature of cooking cavity and fire door 13 can rise.But, when designing, traditional ventilation hood type microwave furnace do not consider the cooling of fire door 13, therefore, when opening and closing fire door 13, the user scalded by fire door 13 easily.
In addition, in order to cool off magnetron 21 electronic units such as grade in the distribution chamber 20, two cooling fans 23,25 have been adopted.Therefore, not only increase power consumption, but also aggravated the noise that cooling fan 23,25 produces.
