The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
As shown in Figure 4, the convection-microwave oven of the preferred embodiment of the present invention is made of micro-wave oven body 100, cavity 200, electronic components chamber 300, convection section and bonnet 140.
Micro-wave oven body 100 forms the outward appearance of micro-wave ovens, is made of the front panel 110 that forms the micro-wave oven leading flank, the shell 120 that forms micro-wave oven two sides and upper side and the rear board 130 that forms the micro-wave oven trailing flank.
Also include the bonnet 140 that is arranged on electronic components chamber 300 rear sides on the micro-wave oven body 100.
Cavity door 111 is installed on the front panel 110, and described cavity door 111 is used to open and close the inside of cavity 200 when forming the leading flank of micro-wave oven bodies 100.
Protect cavity 200 and electronic components chamber 300 with front panel 110, rear board 130, bonnet 140 in the time of the two sides of shell 120 formation micro-wave oven bodies 100 and upper side.
Rear board 130 is arranged on the trailing flank of cavity 200, is formed with a plurality of intercommunicating pores 201 that are communicated with the inner space of cavity 200 on its central part roughly, and the back of rear board 130 is provided with the convection section with any space.
Rear board 130 utilizes hear resistance and the strong stainless steel material of corrosion resistance to make.This is in order to prevent because the heat that the cooking room 210 of cavity 200 inside produces makes rear board 130 distortion, and prevents to be corroded owing to salinity and moisture that gratin produces.
Convection section is arranged on the rear side of micro-wave oven body 100, provides heat of high temperature by described convection section to cooking room 210.
Convection section is made of convection cell 410, convection heater 420, convection cell motor 430 and adverse current fan 450.
Convection cell 410 is arranged on the rear side of the rear board 130 of micro-wave oven body.
Convection heater 420 is arranged on the inner space of convection cell 410, heating and the hot gas of high temperature is provided.
By convection fan 440, the hot gas of the high temperature that is produced by convection heater 420 is provided to cooking room inside by each hot gas supply hole of cavity 210.
Convection cell motor 430 is fixed on the back of convection cell 410, and the mode combination that combines with axle with convection fan 440, and its effect is to be used to drive convection fan 440.
Adverse current fan 450 is arranged on the rear side of convection cell 410, is used for heat release convection cell motor 430 and produces heat.
Convection cell cover cap 500 is arranged on the rear side of convection section, is used to protect the member in the convection section.
Electronic components chamber 300 is arranged on the opposite side space in the micro-wave oven body 100, and its inside is provided with various electronic components such as high-tension transformer 310, magnetron 320.
At this moment, the rear space in the electronic components chamber 300 is provided with the Air Blast fan 330 and the fan electromotor 340 of the heat that is used for 300 inside, ejected electron accessory chamber.
The rear side of electronic components chamber 300 is provided with bonnet 140, protects the member of 300 inside, electronic components chamber with shell 120.
Convection cell cover cap 500 forms one with bonnet 140 in the embodiments of the invention.
Furtherly, utilize single material and make convection cell cover cap 500 and bonnet 140 in the mode of one with single operation.
Convection cell cover cap 500 with the manufacture process of bonnet 140 is: after utilizing heat melts to be used to make the material of convection cell cover cap 500 and bonnet 140, utilize casting technique to inject the product of producing required shape behind the casting mold.
Though convection cell cover cap 500 can be made by the single casting process with bonnet 140, in order to produce in batches and in order to reduce manufacturing expense, to come to make of casting technique.
In order to reduce the manufacturing expense of product, convection cell cover cap 500 uses material-stainless cheap material of comparing rear board 130 to make with bonnet 140.The cheap ferrous materials of the convection cell cover cap 500 of the preferred embodiment of the present invention and bonnet 140 usefulness is made.
In addition, convection cell cover cap 500 and bonnet 140 do not contact with cooking room 210 because different with shell 120 and rear board 130, so seldom corrosion such as salinity that is produced by cooking room 210 and moisture.
The shell 120 and the rear board 130 that are directly exposed to cooking room 210 must be made by the higher material-stainless steel of price, just can prevent to be subjected to corrosiveness and be out of shape, convection cell cover cap 500 uses cheap material, the manufacturing expense that can reduce product with bonnet 140.
The following describes the assembling process of the outward appearance of aforesaid convection-microwave oven:
At first shown in Fig. 5 a, the rear side of the cavity 200 in the rear side position of shell 120 is attached to rear board 130 on the shell 110.Then shown in Fig. 5 b, the rear side of plate 130 is provided with convection section in the back.Shown in Fig. 5 c, connect the convection cell cover cap 410 and the bonnet 140 that form one mutually then.
Convection cell cover cap 410 is arranged on the rear board 130 at this moment, is used for around the convection section that is positioned at rear board 130 rear sides.
Meanwhile, bonnet 140 be connected shell 120 around a part of position on, and be arranged on the rear side of electronic components chamber 300, protect the internals of electronic components chamber 300 with shell 120.
By said process, finish the assembling process of the outward appearance of convection-microwave oven.
Convection cell cover cap 410 forms one with bonnet 140 in the embodiments of the invention, and convection cell cover cap 410 has used structure of the prior art, and certainly, bonnet 140 also can be made use in addition.
As shown in Figure 6, an alternative embodiment of the invention has other bonnet 140.
Specifically, make convection cell cover cap 500 and bonnet 140 in an alternative embodiment of the invention respectively, and convection cell cover cap 500 is arranged on the rear side of rear board 130, protect the internals of convection section; Bonnet 140 is arranged on the rear side of electronic components chamber 300, the internals of protection electronic components chamber 300.
At this moment, convection cell cover cap 500 with the manufacture process of bonnet 140 is: after utilizing heat melts to be used to make the material of convection cell cover cap 500 and bonnet 140, utilize casting technique to inject the product of producing required shape behind the casting mold.
Utilize the material more cheap to make in order to reduce convection cell cover cap 500 with the manufacturing expense of bonnet 140 than stainless steel.
According to a further embodiment of the invention, the cheap ferrous materials of convection cell cover cap 500 and bonnet 140 usefulness is made respectively.
As mentioned above, the rear board 130 that links to each other with cooking room uses the high stainless steel material manufacturing of price, be not exposed to bonnet 140 cooking room, that be arranged on electronic components chamber 300 rear sides and use the material manufacturing more cheap, the manufacturing expense that can reduce product than stainless steel.
Though the front is described the present invention in detail, persons of ordinary skill in the art may appreciate that and to make change miscellaneous and modification under the prerequisite in not breaking away from the claim scope.
