The above situation can be effectively prevented by using the wireless power transmission device 13.

Among them, there are various power transmission methods of the wireless power transmission device 13, and the following description will be given by way of example:

for example, in one example, the wireless power transmission device 13 may transmit electric energy using the principle of electromagnetic induction. In such an example, the transmitting element 131 includes a transmitting coil and the receiving element 132 includes a receiving coil. In such a case, the transmitting coil is connected to a power supply device, the power supply device can provide alternating current to the transmitting coil, the transmitting coil generates a constantly changing magnetic field after receiving the alternating current, and the receiving coil is used for generating current when sensing the change of the magnetic field, so that the capability of electric transmission is realized.

Thus, the distance between the emitter 131 and the receiver 132 can be made closer, and the power transmission efficiency is high.

Since the intensity of the magnetic field generated by the emitting element 131 decreases with increasing distance, that is, in the case that the receiving element 132 is spaced far from the emitting element 131, the intensity of the magnetic field sensed by the receiving element 132 decreases, which results in a decrease in the amount of electric energy generated by the receiving element 132, and thus is not beneficial to the transmission of the electric energy. And through the setting of pivot 111, receiving piece 132 is located pivot 111 end, so can make the interval distance of emitting piece 131 with receiving piece 132 nearer, so receive piece 132 can fully induce the magnetic field, and then make the volume of the electric energy that receiving piece 132 produced increase to make transmission of electricity efficiency higher.

In this manner, the power storage 1123 facilitates power supply to the balancers 17 on the two balancing rings 16 to operate the balancers 17 on different balancing rings 16. Thus, a uniform power supply can be formed, the cost is low, and the mass production of the household appliance 100 is facilitated.

It will be appreciated that in other embodiments, where the power storage 1123 is mounted on a balancer 17, each balancer 17 may have a separate power storage 1123, which may form a self-contained power supply that is not susceptible to power outages from other factors.

Referring further to fig. 1, in some embodiments, the household appliance 100 includes a base plate 20 and a vibration damping structure 21, wherein the vibration damping structure 21 connects the base plate 20 and the body 10.

In this manner, the vibration transmitted to the outside of the home appliance 100 can be further reduced.

During the rotation of the cavity 11, vibration may be generated, which may affect the operation of the household appliance 100, and the vibration may generate noise, which may affect the normal life of the user. Through the arrangement of the shock absorption structure, the vibration can be reduced, and further, the operation of the household appliance 100 is more stable.

Specifically, the vibration damping structure 21 includes a supporting pillar 211 provided on the base plate 20 and an elastic member 212 provided on the supporting pillar 211, one end of the elastic member 212 is connected to the supporting pillar 211, and the other end of the elastic member 212 is connected to the body 10. Thus, when the body 10 vibrates, the vibration force is transmitted to the elastic member 212, and then the vibration force and the elastic force of the elastic member 212 are offset, so as to reduce the vibration force transmitted to the outside of the household appliance 100.

The elastic member 212 may be a spring, a leaf spring, or other elastic material. The specific type of the elastic member 212 is not limited herein. In the present embodiment, the elastic member 212 is a spring.

It is understood that in other embodiments, the vibration damping structure 21 may also adopt a hydraulic pressure, an oil pressure, or the like to reduce the transmission of vibration. The details may be set differently depending on the situation. And are not limited herein.
