Description
Technical field
The present invention relates to the micro-wave oven technical field, particularly relate to a kind of micro-wave oven with novel axial-flow fan.
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.
In general, micro-wave oven is divided into single function for microwave oven and multifunction microwave oven, single function for microwave oven is to adopt microwave heating, promptly be a kind ofly to seal, connect the power supply of magnetron after placed within of the food, make it produce high-frequency microwave, by waveguide high-frequency microwave is shone on the food, makes about 2,400,000,000 5 thousand ten thousand times of hydrone internal vibration in a second of food, by the frictional heat that produces between hydrone to cooking food, heating; It is the micro-wave oven of one that multifunction microwave oven adopts microwave heating and other mode of heatings, and common mode of heating has light wave heating and electrothermal tube heating, is also referred to as barbecue type microwave oven.
Fig. 1 is the stereochemical structure decomposing schematic representation of a kind of built-in microwave oven of prior art.As shown in Figure 1, the cavity 1 inner cooking room 4 that forms of this built-in microwave oven.In cooking room 4, finish the heating process of gratin.Side at the cavity 1 on cooking room 4 next doors is provided with electric control chamber 5.
Electric control chamber 5 is provided with the component locations that produces microwave, forms chassis 7 in electric control chamber 5 bottoms.In electric control chamber 5, chassis 7 is provided with high-tension transformer 8.One sidewall of cavity 1 is provided with magnetron 9, and magnetron 9 is to the internal irradiation electromagnetic wave of cooking room 4.Magnetron 9 obtains high voltage from high-tension transformer 8, produces microwave.In electric control chamber 5, also be provided with high-voltage capacitance 10.
In addition, the rear of electric control chamber 5 is provided with demarcation strip 12, and demarcation strip 12 is used to divide electric control chamber 5 and forms the stream of carrying out ventilation function with the backplate 13 of micro-wave oven.
Be provided with air guide passage 15 above the described cavity 1.Air guide passage 15 is from the internal upper part steering current of micro-wave oven.In air guide passage 15, the part that is equivalent to electric control chamber 5 tops is provided with the fan electromotor 18 that is used to drive cooling fan 17.Cooling fan 17 sucks air by air guide passage 15 from the outside, supply air to electric control chamber 5.The heat that electric control chamber 5 air supplied cooling high-tension transformer 8, magnetron 9 and high-voltage capacitance 10 produce, a part is transported to the inside of cooking room 4 and removes the steam that is produced in gastronomical process.
The last surface rear end of air guide passage 15 is provided with and is used for exhaust axial-flow fan 20.Described exhaust is provided with in order to carry out ventilation function with axial-flow fan 20 bodies 19, and the hot gas that cooker produced such as gas burner or the cigarette that are arranged on the built-in microwave oven below are discharged to the outside.
In existing micro-wave oven, exhaust can drive by user's operation with axial-flow fan 20, also can exhaust automatically be driven with axial-flow fan 20 by hot gas of producing in the gastronomical process such as perception gas burner etc.Participate in shown in Figure 1ly, exhaust is finished by temperature relay 11 with the function that axial-flow fan 20 automatically drives.
The hot gas that produces in the gastronomical process such as gas burner is transferred, and then the temperature on chassis 7 will rise, thereby is set at temperature relay 11 perception on chassis 7, will drive this exhaust when to a certain degree above with axial-flow fan 20 operations when temperature rises to.
But for above-mentioned built-in microwave oven, in the lump referring to Fig. 2, described exhaust is provided with two exhaust outlets 21 with the top of axial-flow fan 20, described exhaust outlet 21 be shaped as V-arrangement.Hot gas that cooker produced such as gas burner exhaust will be arranged on built-in microwave oven by these two exhaust outlets 21 with axial-flow fan 20 below or cigarette are when discharge the outside so, described exhaust outlet 21 can form air-flows such as hot gas or cigarettes and hinder, form noise during wedge angle position that the exhaust outlet 21 that makes air communication cross described V-arrangement has, make exhaust produce vibrations simultaneously with axial-flow fan 20, form noise pollution therefore for the environment at micro-wave oven place, badly influence user's daily life, reduced micro-wave oven user's product use experience.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of micro-wave oven with novel axial-flow fan, noise generated by air flow and vibrations when its exhaust that has can reduce exhaust with axial-flow fan, make the micro-wave oven peace and quiet move, guarantee the normal use of micro-wave oven, strengthen micro-wave oven user's product use experience greatly, be of great practical significance.
For this reason, the invention provides a kind of micro-wave oven with novel axial-flow fan, include axial-flow fan 20, described axial-flow fan 20 is provided with at least one exhaust outlet 21, and described exhaust outlet 21 has the edge part of arc.
Preferably, the top of described axial-flow fan 20 is provided with two exhaust outlets 21, described exhaust outlet 21 bottom margins be shaped as arc.
Preferably, the shape of described exhaust outlet 21 surrounding edges all is an arc.
By above technical scheme provided by the invention as seen, compared with prior art, the present invention proposes a kind of micro-wave oven with novel axial-flow fan, noise generated by air flow and vibrations when its exhaust that has can reduce exhaust with axial-flow fan, make the micro-wave oven peace and quiet move, guarantee the normal use of micro-wave oven, strengthen micro-wave oven user's product use experience greatly, be of great practical significance.
