Transmission belt 730 can drive variable velocity zone wheel 720 to rotate under the drive of electrical machine belt pulley 710.Can be with when so driver 400 is run
Drive motor belt wheel 710 rotates, and electrical machine belt pulley 710 drives variable transmission belt 730 to move, and variable transmission belt 730 drives variable velocity zone
The rotation of wheel 720, speed change belt wheel 720 drive the synchronous axial system of driving pulley 100, thus can not only realize driver 400 to actively
The driving effect of belt wheel 100, and can be by setting electrical machine belt pulley 710 and the size of speed change belt wheel 720 to realize gear
The gear function of component 700.
For example, when needing gear component 700 to have deceleration transmission function, the diameter of speed change belt wheel 720 can be big
In the diameter of electrical machine belt pulley 710.So when 710 turns of a few circles of electrical machine belt pulley, speed change belt wheel 720 turns around, and realizes gear
The deceleration transmission effect of component 700, it is possible thereby to increase the torsion of the output of driver 400, it is strong to improve the load of driver 400
Degree.
In order to prevent variable transmission belt 730 from skidding, motor tooth 711 can be set in the outer peripheral face of electrical machine belt pulley 710, become
The outer peripheral face of speed belt wheel 720 sets gear teeth 721, and gear tooth 731, speed change are set in the inner peripheral surface of variable transmission belt 730
Driving cog 731 can engage with motor tooth 711 and gear teeth 721 respectively.Electrical machine belt pulley 710 and speed change belt wheel can so be avoided
720 occur to slide relatively with variable transmission belt 730, to improve electrical machine belt pulley 710 and speed change belt wheel 720 and variable transmission belt 730
The reliability of cooperation.Also, in transmission process, variable transmission belt 730 and electrical machine belt pulley 710 and speed change belt wheel 720 all the time with
The burden for multiple teeth, alleviating each tooth is shared in multiple tooth contacts, the load of transmission, so as to ensure that variable transmission belt
730 and electrical machine belt pulley 710 and speed change belt wheel 720 there is longer service life.
Fig. 2-Fig. 5 shows the micro-wave oven 1 according to a specific example of the invention.As Figure 2-Figure 5, drawer door switch
Device 30 can also include fixed mount 800, and driving pulley 100, speed change belt wheel 720 and driven pulley 200 can rotatably pacify
On fixed mount 800, driver 400 may be mounted on fixed mount 800.In other words, driving pulley 100, speed change belt wheel
720th, driven pulley 200 and driver 400 can be arranged on one in shaft 10 and drawer door 20 by fixed mount 800
On.It is possible thereby to make drawer door switch unit 30 form a stable entirety, drawer door switch unit 30 can be not only improved
The reliability of performance, and can be in order to the assembling of micro-wave oven 1.
Wherein, driving pulley 100 and speed change belt wheel 720 can be rotatably installed in fixed mount by active rotating shaft 110
On 800, driven pulley 200 can be rotatably installed on fixed mount 800 by driven spindle 210.
