Several through holes 13a communicate with the inner space of cavity 20 is set on the substantial middle position of plate 13 in the back, and the back of described rear board 13 be provided with and rear board 13 between the convection current case 31 in the certain space of formation.
The inboard, space that convection current case 31 possesses is provided with convection heater 32 and temperature sensor 33, make thermal current that described convection heater 32 produces convection fan 34 and be provided with to cavity 20 inside in the inboard of convection current case 31, be provided with the convection current case motor 35 that drives convection fan 34 in the back of convection current case 31, convection fan 34 adopts the mode that is coupling to be connected with convection current case motor 35.
Be provided with the case lid 37 of protection convection current case 31 and convection current case motor 35 at the rear of convection current case 31.Described case lid 37 is fixed on the rear board 13 when surrounding convection current casees 31 and convection current case motor 35.
Be provided with a plurality of suction hole 37a that suck outside air in the back of case lid 37.
Be provided with magnetron 41 that produces microwave and the Air Blast fan 43 and the fan electromotor 44 that drives Air Blast fan 43 that the high voltage transformer 42 of high tension voltage is provided and cools off the various electrical equipments of shaft 10 inside to magnetron 41 in the inside of electric control chamber.
Fan electromotor 44 is fixedly installed on rear board 13 sides, and Air Blast fan 43 around be provided with screen board, flow in order to the guiding air.
But as above the convection-microwave oven of the prior art of She Zhiing is owing to be arranged on the thickness of rear convection current case 31 and convection current case lid 37, and the front and back length of its integral body increases, and trouble not only is installed, and needs the bigger space that is provided with.
Particularly when products export, because volume is excessive, the open ended quantity of container will reduce, and has therefore increased cost of transportation.
And, because the structure of the inner generation of micro-wave oven high temperature hot gas is too complicated with the structure of carrying out convection current, has therefore not only improved the manufacturing cost of whole goods, and increased workload again.
Summary of the invention
In order to solve above problem, the purpose of this invention is to provide a kind of convection-microwave oven, when it has minimized the front and back length of micro-wave oven, can provide the hot gas of higher temperature to the inside of heating clamber.
In order to achieve the above object, technical scheme of the present invention provides a kind of convection-microwave oven, include the shaft that shell, rear board with a plurality of through holes that constitutes top and two sides and the front panel that constitutes front portion structure are formed, wherein: also include the internal convection case that is fixed on the certain space of formation on the rear board, be provided with through hole on the face around the described convection current case, the rear board of convection current case is provided with a plurality of suction holes; In the space of described convection current case, be set with convection current case motor, convection fan on the position of suction hole and be arranged on convection current case convection heater on every side; Described convection current case motor is arranged in the inner space of convection current case by the motor guides device; Described convection current case motor adopts dual-axle motor, and its front axle is provided with convection fan, and side shaft is provided with for convection current case motor and has the blower fan of thermolysis thereafter.
Effect of the present invention is that this convection-microwave oven need not to be equipped with case lid, when can save the manufacturing expense of case lid thus, can save the installation procedure of case lid.Secondly, because convection-microwave oven is not established case lid, length before and after therefore can shortening.Because it is perfect that its heat radiation is provided with, therefore can avoid the overheated damage that causes parts.

The specific embodiment
Below, with reference to the embodiment of accompanying drawing 3,4 detailed descriptions convection-microwave oven of the present invention.
At first, as shown in Figure 3 and Figure 4, the convection-microwave oven structure in the embodiments of the invention comprises: shaft 100, cavity 200, convection current case 310, convection current case motor 350 and convection fan 340 and convection heater 320 constitute.
The shaft 100 that forms the micro-wave oven outward appearance comprises: the rear board 130 of front panel 110, the shell 120 that constitutes both sides and top structure and formation back structure constitutes.
Plate 130 is provided with the through hole 131 that heating clambers a plurality of and in cavity 200 inner spaces communicate in the back.Certainly, the back of cavity 200 is provided with a plurality of through holes 201 equally.
Convection current case 310 has certain space in inside when the through hole 131 that surrounds rear board 130 forms the position, the front of convection current case 310 is close to around the back of described rear board 130 on every side.
Face is provided with the 1st suction hole 311 of a plurality of absorption outside airs around the convection current case 310.
And convection current case motor 350 and convection fan 340 are positioned at the inner space of convection current case 310.
Convection current case motor 350 and convection fan 340 offer high temperature hot gas by each through hole 131 of rear board 130 inside of heating clamber.
Convection current case motor 350 can directly be fixedly installed on the inner face of described convection current case 310, but preferably utilizes the motor guides device to install in addition, utilizes motor guides device 351 to install and fix motor 350 in the present invention.
The medial surface that motor guides device 351 can be arranged on convection current case 310 also can be arranged on the back of rear board 130.
When convection current case motor 350 starts, need make the discharge of hot gas smooth more.
Particularly in the inner space of the convection current case 310 that is provided with convection current case motor 350 owing to be provided with convection heater 320, so temperature inside will be very high.Impaired for fear of convection current case motor 350 high temperature, should make the hot gas smoothness of discharge.
Certainly, be provided with convection fan 340 in convection current case 310 inside, convection fan 340 will be expelled to heating clamber inside with the hot gas that convection heater 320 produces by the air of convection current case motor 350 inflow convection current casees 310 inside, therefore reduce the temperature in space to a certain extent.
But, in an embodiment of the present invention, in order further to improve the exothermal efficiency of described convection current motor 350, increase in the back of the convection current case 310 of convection current case motor 350 rear sides and to be provided with the 2nd suction hole 312 of drawing outside air.
Meanwhile, in an embodiment of the present invention, described convection current case motor 350 adopts dual-axle motor, appends on the axle at convection current case motor 350 rears and is provided with blower fan 360.The front axle of dual-axle motor is provided with convection fan, and side shaft is provided with the blower fan that has thermolysis for the convection current motor thereafter.
At this moment, blower fan 360 is delivered to forcing ambient air on the convection current case motor 350.
Thus, even convection current case motor 350 is because its heat release and owing to the heat release of convection heater 320 is heated intensification when starting, owing to be arranged on the wind-force effect of the convection fan 340 in the same space with convection current case motor 350, the hot gas of convection current case motor 350 provides inside to heating clamber with the hot gas of convection heater 320, so heating clamber can obtain the hot gas of higher temperature.
Certainly, motor 350 can utilize the blower fan 360 that is arranged on its rear side to dispel the heat, and can farthest prevent impaired.
Not only case lid of the prior art can be removed according to embodiments of the invention, and entire length can be reduced thus.
