Abstract
The utility model relates to a transmission mechanism of a mode stirrer of a microwave device, which comprises a wheel shaft connected with an impeller of the mode stirrer, a motor, a motor bracket and a metal shielding cover. The utility model is characterized in that engineering plastics are adopted by the wheel shaft of the impeller, a transmission shaft of the motor is a metal shaft, a plastic wheel shaft is fixedly reconnected with the metal transmission shaft of the motor or the outer end of the plastic wheel shaft is fixedly connected with a gear which is re-meshed with a gear on the metal transmission shaft of the motor or the outer end of the plastic wheel shaft is fixedly connected with a belt pulley which is connected with a belt pulley group on the metal transmission shaft of the motor by a belt.
Description
The utility model relates to a kind of driving mechanism of mode stirrer (claiming microwave stirrer again) of microwave device.
The utility model is the improvement to international application no PCT/CN00/00478 (international filing date on November 20th, 2000) denomination of invention " multifunction microwave device ", the applicant has proposed to blow with centrifugal blower the wheel rotation of mode stirrer in this international application, adopt this mode to promote mode stirrer deficiency is also arranged, the one, increase by a typhoon machine product cost is increased, the 2nd, make the volume of product increase the occupation space increase.
Well-known microwave oven mainly is by the magnetron launched microwave when working, by waveguide microwave is imported in the furnace chamber food is heated, for making the capacity of furnace evenly also for the food in the furnace chamber is evenly heated, the general rotating disk that drives by motor that on drop-bottom, is equipped with, with dial rotation food owing to can increase motor power, also make motor driving mechanism complexity and energy even poor, therefore people imagine and adopt many mouthfuls of couplings, and install mode stirrer (claiming microwave stirrer again) object to be processed additional need not rotation and just can obtain more uniform energy in wave guide box.Drive mode stirrer by motor, but because the rotating shaft of motor shaft and mode stirrer is an one, if adopt metal shaft, can and microwave action produce spark and destroy chamber structure, and rotating shaft is passed hearth wall and is had the space and produce microwave leakage and motor is produced destruction; If motor drive shaft or impeller shaft are adopted engineering plastics, then can directly be penetrated by microwave because of plastics, and every hole microwave greater than 3mm just can release, cause microwave to hit motor, so can not adopt the plastic shaft of diameter greater than 3mm, if adopt the engineering plastics axle of diameter, can not use because of insufficient strength or non-refractory less than 3mm.Therefore the kind of drive that directly drives the mode stirrer impeller shaft with motor is not used for actual product always.
The purpose of this utility model be to provide a kind of can with motor directly drive mode stirrer rotating shaft, and can reduce product cost, save the space, motor can not be subjected to microwave to hit the driving mechanism of the mode stirrer that destroys.
The purpose of this utility model realizes with the following methods.The driving mechanism of this mode stirrer comprises wheel shaft, motor, motor bracket, the metallic shield that is connected with the impeller of mode stirrer, the wheel shaft that it is characterized in that impeller adopts engineering plastics, the transmission shaft of motor is a metal shaft, the plastics wheel shaft is fixedlyed connected with the metal drive shaft of motor again, or the affixed gear in the outer end of plastics wheel shaft, this gear again with the motor metal drive shaft on gear engagement, or the affixed belt pulley in the outer end of plastics wheel shaft, this belt pulley is connected with belt pulley on the motor metal drive shaft by belt.
Below in conjunction with embodiment's accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model embodiment 1 structural representation
Fig. 2 is the utility model embodiment 2 structural representations
Fig. 3 is the utility model embodiment 3 structural representations
Among the figure: the transmission pulley 11-drivign belt 12-wave guide box on the belt pulley 10-transmission shaft on the driving gear 9-wheel shaft on the driving gear 8-transmission shaft on the wheel shaft 3-motor bracket 4-metallic shield 5-mode stirrer impeller 6-motor drive shaft 7-wheel shaft of 1-motor 2-mode stirrer
Embodiment 1 shown in Figure 1 is that the wheel shaft (2) of mode stirrer adopts engineering plastics such as teflon, motor drive shaft (6) is a metal shaft, transmission shaft (6) is fixedlyed connected with plastics wheel shaft (2), the big I of the diameter of plastics wheel shaft (2) is by the necessary requirement Intensity Design, because plastics wheel shaft (2) is to be connected with metal drive shaft (6) outside wave guide box (12), during microwave work, microwave by plastics wheel shaft (2) can so just can not produced destruction to motor (1) by metal drive shaft (6) reflection.Embodiment 2 shown in Figure 2 is affixed gears in outer end (7) of the wheel shaft (2) of mode stirrer, this gear (7) again with the motor metal drive shaft on gear (8) engagement, during microwave work, microwave by plastics wheel shaft (2) is the direct internal structure of impact motor (1) not, but is reflected by metallic shield (4).Embodiment 3 shown in Figure 3 is affixed belt pulleys in outer end (9) of the wheel shaft (2) of mode stirrer, and this belt pulley (9) is connected with belt pulley (10) on the motor metal drive shaft by belt.Microwave by plastics wheel shaft (2) when the mode that is in transmission connection of the wheel shaft (2) of this motor (1) and mode stirrer also can be avoided microwave work effectively is directly to the destruction of the internal structure of motor (1).
The kind of drive of three kinds of different mode stirrers can be adapted to can adopt different driving mechanisms according to different situations in the different microwave devices in the utility model.
Claims (1)
1, a kind of driving mechanism of mode stirrer, comprise the wheel shaft (2) that is connected with the impeller (5) of mode stirrer, motor (1), motor bracket (3), metallic shield (4), the wheel shaft (2) that it is characterized in that impeller (5) adopts engineering plastics, the transmission shaft (6) of motor (1) is a metal shaft, plastics wheel shaft (2) is fixedlyed connected with the metal drive shaft (6) of motor again, or the affixed gear in the outer end of plastics wheel shaft (2) (7), this gear (7) again with the motor metal drive shaft on gear (8) engagement, or the affixed belt pulley in the outer end of plastics wheel shaft (2) (9), this belt pulley (9) is connected with belt pulley (10) on the motor metal drive shaft by belt (11).
