Abstract

The utility model provides a microwave oven with heated air circulation function, includes cavity (1) and heated air circulation mechanism, wherein heated air circulation mechanism includes heating tube (2), hot-blast fan (5), sealed cowling (14), cooling fan (10), heat insulating board (15), motor element and back shroud (13), wherein hot-blast fan (5), sealed cowling (14), cooling fan (10), heat insulating board (15), motor element and back shroud (13) install in proper order at the cavity rear portion, its characterized in that above-mentioned heating tube (2) are arranged in cavity (1). The utility model discloses because the heating tube is arranged in the cavity, consequently, temperature rise is fast in the cavity during culinary art, and food heating is fast, and in addition, among the heat transfer process, the loss is little, and heating efficiency is high, need not install the heating tube cover moreover, has simplified the structure greatly.

Description

Micro-wave oven with hot air circulation function
Technical field
The utility model is a kind of micro-wave oven, particularly a kind of micro-wave oven with hot air circulation function.
Background technology
At present, commercially available micro-wave oven with hot air circulation function, its structure as shown in Figure 1, comprise cavity 1, heat-generating pipe support 4, hot blast fan 5, heat-generating pipe 2, heating tube cover 7, heat insulation foam 8, thermal insulation board 9, cooling fan 10, electric machine support 11, motor 12 and back shroud 13, wherein above-mentioned heat-generating pipe support 4, hot blast fan 5, heat-generating pipe 2, heating tube cover 7, heat insulation foam 8, thermal insulation board 9, cooling fan 10, electric machine support 11, motor 12 and back shroud 13 are installed in the cavity outside successively, the back plate of cavity 1 is provided with thermal hole, motor 12 is used to drive hot blast fan 5 and cooling fan 10 rotates, during micro-wave oven work, heat-generating pipe 6 begins heating, hot-air enters in the cavity by thermal hole, because the hot blast fan rotates, accelerate entering of hot-air, simultaneously the cold air of cavity 1 inside by 5 sucking-offs of hot blast fan after again through heat-generating pipe heating becoming hot-air, enter again in the cavity 1, so form hot air circulation, improve the firing rate of food.Cooling fan 10 sucks outside cold air by the wind inlet on the back shroud 13, is used to cool off thermal insulation board 9, electric machine support 11, motor 12 and back shroud 13.The micro-wave oven defective of said structure is: because heat-generating pipe is positioned at the cavity outside, the interior temperature of cavity rises slowly during work, and heat food is also slower; In addition, in the heat transfer process, have certain loss, for example the back plate of fan, heating tube cover and cavity unavoidably all will absorb heat, therefore greatly reduces the micro-wave oven efficiency of heating surface.
The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of heating fast, the efficient height, and the micro-wave oven with hot air circulation function simple in structure is to overcome weak point of the prior art.
A kind of micro-wave oven by this purpose design with hot air circulation function, comprise cavity and hot air circulation mechanism, wherein hot air circulation mechanism comprises heat-generating pipe, hot blast fan, seal closure, cooling fan, thermal insulation board, electric machine assembly and back shroud, wherein hot blast fan, seal closure, cooling fan, thermal insulation board, electric machine assembly and back shroud are installed in the cavity rear portion successively, it is characterized in that above-mentioned heat-generating pipe places in the cavity.
Above-mentioned cavity back shroud is provided with several inlet scoops and several air outlets, and several air outlets are positioned at the periphery of several inlet scoops.
The periphery of inlet scoop is provided with the inclined-plane on the above-mentioned cavity back shroud, and several air outlets are arranged on the inclined-plane.
The utility model places in the cavity owing to heat-generating pipe, and therefore, the interior temperature of cavity rises soon during culinary art, and food heats soon, and in addition, in the heat transfer process, loss is little, efficiency of heating surface height, and do not need to install heating tube cover, simplify the structure greatly.
