Description

A kind of micro-wave oven with the function that blows on automatically

Technical field

The utility model relates to field of mechanical technique, particularly relates to a kind of micro-wave oven with the function that blows on automatically.

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.

At present, as shown in Figure 1, micro-wave oven generally includes: comprise the body 10 of front casing 11, shell 12 and outside framework 13, form the cavity 20 of culinary art chamber, and the inner electric control chamber 30 that various electric components are installed.

Front casing 11 forms the front portion of body 10, is provided with door of microwave oven 14 in the above, realizes the opening and closing of cavity 20 inside by this fire door 14.Outside framework 13 forms the bottom surface and the back of bodies 10, realizes protection to cavity 20 and electric control chamber 20 with shell 12, front casing 11.

Described electric component comprises: be used to generate the magnetron 31 of microwave, be used for providing to magnetron 31 high-tension transformer 32 of high pressure, and be used for blowing fan 33 that body 10 inner various electric components are cooled off.

To come cooking food can only be that the temperature of food is risen in view of depending merely on microwave, therefore usually as shown in Figure 2, the heater of being made by heating tube, the auxiliary heating source of conduct uses 40 is installed on microwave oven cavity 20 tops, by heater 40, food was toasted as the quilt fire, thereby increase appetite of people, in addition, when utilizing heating using microwave, drive the heater 40 that uses as auxiliary heating source, can shorten the cooking time of food.

In recent years, electromagnetic oven has obtained popularizing more and more widely as a kind of novel kitchen range in kitchen tools market.It has broken the heating principle that traditional naked light cooking method adopts magnetic field induction electric current (being called eddy current again), electromagnetic oven is to produce alternating magnetic field by the electronic circuit board part, when when containing irony pan bottom and place boiler face, pan promptly cuts the alternation magnetic line of force and partly produces the electric current (being eddy current) of alternation in the pan bottom metal, eddy current makes the random motion of pan iron molecule high speed, molecule runs foul of each other, friction and produce heat energy (so: the thermal source that electromagnetic oven is cooked comes from pan bottom rather than electromagnetic oven heating conduction itself to pan, so the thermal efficiency all exceeds nearly 1 times than the efficient of all cookers), make utensil heating at a high speed voluntarily itself, be used for heating and cooking food, thereby reach the purpose of cooking.Have quick heating, thermal efficiency height, the flames of anger, no flue dust, no pernicious gas, to surrounding environment do not produce heat radiation, volume is small and exquisite, safe and advantage such as appearance looks elegant, the overwhelming majority that can finish family cooks task.Therefore, in some countries that electromagnetic oven is popularized, the refreshing ＂ and the green stove and accessory ＂ of ＂ for the ＂ culinary art of people's reputation.

But, because in order to reach Fast Heating or to reach the purpose of thorough heating, behind the microwave oven heating food, boiling hot excessively after food heating often occurring and finishing, could eat after causing needs to place the cold of drying in the air, therefore cause the user to waste the plenty of time wait, even the consequence that when the user neglects, can cause the user to scald.

Therefore, press at present and develop a kind of micro-wave oven, can realize to select after micro-wave oven heats the function that blows on automatically of certain time length,, strengthen the experience of user the micro-wave oven product to save user's time.

The utility model content

In view of this, the purpose of this utility model provides a kind of micro-wave oven with the function that blows on automatically, can be by increasing simple parts, realize to select after micro-wave oven heats the function that blows on automatically of certain time length, save user time, make things convenient for the user to live and greatly expanded the function of existing micro-wave oven, concrete great production practices meaning.

For this reason, the utility model provides a kind of micro-wave oven with automatic blowing function, comprise shell 1 and cooking cavity 2, described cooking cavity 2 is positioned at shell 1, the bottom of described cooking cavity 2 is provided with cooking tray 3, at least one fan 4 is set on the described cooking cavity 2, and described fan 4 is connected with external power supply.

Preferably, described fan 4 is positioned on the left side wall of described cooking cavity 2.

Preferably, be provided with timing circuit between described fan 4 and the external power supply, with the rotation running time of control fan 4.

Preferably, the circuit of the circuit of described micro-wave oven and described fan 4 is formed parallel circuit, connects timing circuit then, is controlled by timing circuit, and timing circuit connects external power supply again.

The technical scheme that is provided by above the utility model as seen, the utlity model has the micro-wave oven of automatic blowing function, can be by increasing simple parts, promptly in cooking cavity 2, increase fan 4 is set, according to the existing electric component of micro-wave oven is the basis, realizes can selecting after micro-wave oven heats the function that blows on automatically of certain time length, has simple installation, greatly expanded the function of existing micro-wave oven, concrete great production practices meaning.
