Moreover, the stability of power transmission can be improved by such a power transmission mode, and the power transmission mode is not easily influenced by the washing machine in the power transmission process, for example, the washing machine can generate vibration during working, if power transmission is performed through a lead, the lead can be driven to move when the vibration generated in the working process of the washing machine is large, and then the lead can be separated from the washing machine, so that the power transmission is abnormal. 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 transfer device 13 may employ the principles of electromagnetic induction for the transfer of electrical energy. 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.

In such an example, the transmitting element 131 includes a first resonance coil, and the receiving element 132 includes a second resonance coil. The first resonance coil and the second resonance coil can be driven to vibrate at the same frequency, the first vibration coil can radiate an electromagnetic field in the vibration process, and the second resonance coil can receive the magnetic field change and convert the magnetic field change into electric energy in the vibration process, so that the electric transmission capacity is realized.

For another example, in another example, the Wireless power transmission device 13 may transmit the electric energy by using a WIFI (Wireless Fidelity, wireless local area network) Wireless charging principle. In such an example, the transmitting element 131 includes a charging sensor and the receiving element 132 includes a router. The charging sensor is connected with the power supply equipment, and the power supply equipment can supply power for the charging sensor so that the charging sensor releases electric energy to the outside, and the router can add and receive the electric energy and generate current, so that the point transmission capability is realized.

It will be appreciated that the above description refers to the wireless power transfer means 13 and the specific power transfer being remote by way of example only. In other embodiments, the wireless power transmission device 13 may transmit power in other manners. For example, in another embodiment, the wireless power transmission device 13 may perform wireless charging using radio waves or ultrasonic waves. The design can be specifically designed according to actual conditions. And is not limited thereto. It is only necessary that the transmitting element 131 and the receiving element 132 cooperate to enable the transfer of electrical energy. And is not limited thereto.

In the present embodiment, the power transmission method of the wireless power transmission device 13 employs the electromagnetic induction principle.

Further, both the body 10 and the cavity 11 can be made of stainless steel. The stainless steel has advantages of high hardness and strong corrosion resistance, so that the lifespan of the body 10 can be increased. It will be appreciated that the body 10 may be made of more than stainless steel. The material of the body 10 is not limited herein, and may be selected according to actual conditions.

In some embodiments, the household appliance 100 includes a support bracket 112, the support bracket 112 is mounted in the cavity 11, and the receiving member 132 is disposed on the support bracket 112.

So configured, the fixing of the receiving member 132 is facilitated, facilitating the normal operation of the receiving member 132.

Referring to fig. 2, 4 and 5, in some embodiments, the household appliance 100 includes a rotating shaft 111, the rotating shaft 111 is installed in the cavity 11, the rotating shaft 111 can rotatably penetrate through the body 10, and the receiving member 132 is located at an end of the rotating shaft 111.

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 and receiving piece 132 nearer, so receiving piece 132 can be fully induced magnetic field, and then make the volume of the electric energy that receiving piece 132 produced increase to it is higher to make transmission of electricity efficiency.

The specific distance between the emitting element 131 and the receiving element 132 can be designed according to practical situations. And are not limited herein.

Further, the receiving member 132 and the end of the rotating shaft 111 can be connected by screwing, clipping, gluing, etc. This facilitates the mounting and dismounting of the receiver 132.

Specifically, as can be seen from the example of fig. 5, the supporting frame 112 includes a central portion 1121 and a plurality of connecting arms 1122 connected to the central portion 1121, the plurality of connecting arms 1122 are disposed around the supporting portion 141 at intervals, and the rotating shaft 111 is disposed at the central portion 1121. In the present embodiment, the number of the connecting arms 1122 is three. In other embodiments, the number of connecting arms 1122 can be two, three or less, etc. The specific number of connecting arms 1122 can be set as desired. And is not limited thereto.

Further, the connecting arm 1122 may be integrally formed with the central portion 1121 or may be formed separately. The specific setting can be according to different situations. And are not limited herein.

In particular, in the present embodiment, since vibration is generated during the rotation of the housing 11, the transmitting element 131 or the receiving element 132 may be displaced, and in the case that the receiving element 132 or the transmitting element 131 is displaced, the power transmission efficiency of the transmitting element 131 and the receiving element 132 may be affected, and thus the operation of the wireless power transmission device 13 may be affected. And the emitting element 131, the receiving element 132 and the rotating shaft 111 are coaxially arranged, so that under the condition that the washing machine works or is static, the emitting element 131, the receiving element 132 and the rotating shaft 111 cannot deviate or have smaller deviation, thereby improving the power transmission efficiency and being beneficial to the normal work of the wireless power transmission device 13.

Thus, when in maintenance and replacement, the cavity 11 does not need to be disassembled, and the wireless power transmission device 13 is convenient to install and debug.

Since the end of the rotation shaft 111 is located outside the body 10 and the receiving member 132 is located at the end of the rotation shaft 111, that is, in such a case, the receiving member 132 can be located outside the body 10, so that when the receiving member 132 is abnormal, a user can repair or replace the receiving member 132 conveniently, and the user does not need to remove the chamber 11 and then repair or replace the receiving member 132. Moreover, since the emitting element 131 is located on the body 10 and the receiving element 132 is located outside the body 10, the wireless power transmission device 13 can be conveniently installed and debugged by a user, that is, both installation and debugging can be performed outside the body 10, so that convenience and rapidness are achieved, and the user experience is improved.

Specifically, the body 10 is formed with a through hole 101, and the end of the rotating shaft 111 passes through the through hole 101 and is exposed out of the body 10. Wherein, the perforation 101 may be circular, rectangular, triangular, etc. The specific shape of the perforations 101 is not limited herein. It should be noted that the cross-sectional area of the through hole 101 is larger than that of the rotating shaft 111, so that the rotating shaft 111 can penetrate through the through hole 101 and be exposed out of the body 10.
