Description
Technical field
The present invention relates to a kind of micro-wave oven.Particularly relate to the cross-flow fan setting structure of the micro-wave oven on rear side of a kind of microwave oven cavity.
Background technology
In general, micro-wave oven to be put into by food and after sealing, switch on power to the magnetron that can produce high frequency waves, and by consequent microwave irradiation on food, make formation cook the molecule of thing 1 internal vibration in second 2,400,000,000 5 thousand ten thousand times, utilize the cookware that the frictional heat produced is cooked food whereby.
The easy control temperature of micro-wave oven, each position due to food can generate heat and can cooking uniformity all size and variform food simultaneously, and has and save cooking time and the multiple advantage such as easy and simple to handle, so be widely used in general family.
As shown in Figure 1, micro-wave oven has the outward appearance of general lineal hexahedral shape, is by forming the external shell 12 of micro-wave oven outward appearance and can shielding the entirety that the door 20 before external shell 12 forms selectively.
Above external shell 12 and two sides are integrally formed, and are fixedly connected on bottom panel and rear board (not shown).
In the inside of micro-wave oven, be formed with the cavity 12 of the lineal hexahedral shape of the front openings can putting into food in order to cooking food, to cavity 12 inside place the container of food is housed after, by microwave irradiation on food, with this, food is cooked.
In the inside bottom surface of described cavity 12, have the pallet 14 that can support the container that food is housed, pallet 14 is connected with the motor (not shown) producing revolving force and rotates, and cooking uniformity is positioned over the food on pallet 14 thus.
The front of cavity 12 opening is provided with door 20.Door 20 is arranged for benchmark rotationally with the hinge 22 being positioned at cavity 12 above top and the bottom, side, thus can selectively before shielding cavity 12.After door 20 shields cavity 12, the microwave produced during micro-wave oven work would not leak into the outside of described cavity 12.
Being provided with below of door 20 be approximately
the door lock 24 of shape vertical section.Door lock 24 will be inserted into the door lock insert port 16 li be formed at before cavity 12.Door lock insert port 16 is formed on the position corresponding with door lock 24, from having longitudinally longer rectangular shape during forward observation.
At the rear side of door lock insert port 16, micro switch (not shown) is installed.Micro switch (not shown) plays the effect optionally making lamp (not shown) be energized, and door lock 24 is inserted into door lock insert port 16 li, is controlled the power supply of turn-on lamp (not shown) by the interference of door lock 24 end.Forwards rotary door 20 and by door lock 24 from after door insert port 16 is drawn, the interference of door lock 24 pairs of micro switch (not shown) can be removed, thus the power supply of turn-on lamp (not shown) and put bright light (not shown).
The right side of cavity 12 or upside have the control part 30 comprising multiple action button 32 and display part 34.Control part 30 is connected with the multiple parts being arranged on microwave oven electric control chamber 6 inside, controls micro-wave oven thus by controlling these parts.
At present, in order to expand the function of micro-wave oven, the top of microwave oven cavity is provided with the barbecue tube for roasting food, the rear side of microwave oven cavity is provided with the fan that heat barbecue tube produced is distributed in the diverse location of microwave oven cavity, as the axial-flow fan arranged in the posterior lateral of microwave oven cavity simultaneously.But, when carrying out roasting, square baking tray food container can be used.When placing baking tray in furnace chamber, the heat-transfer effect of horizontal axial-flow fan directly can be had influence on.Once centre is provided with baking tray, namely furnace chamber becomes upper and lower two regions, and its air intake position is divided into two parts by baking tray.Also just mean that after putting baking tray, in stove, top and the bottom are each integral, the heat of bottom has been wasted most.Cause the result of overall thermal cycle weak effect.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of middle wind can avoiding causing during horizontal fan large, the phenomenon that both sides are calm, and the phenomenon that air-flow is not smooth, reduces hot blast to the cross-flow fan setting structure of the micro-wave oven of the distortion of fan.
The technical solution adopted in the present invention is: a kind of cross-flow fan setting structure of micro-wave oven, include microwave oven cavity, the arranged outside of the rear wall of described microwave oven cavity has the fan volute being longitudinally provided with axial-flow fan in inside, described microwave oven cavity rear wall has the air inlet corresponding with the exhaust outlet in described fan volute and the air outlet corresponding with the air intake vent in described fan volute, the exhaust outlet place of fan volute is provided with roasting pipe structure.
