Embodiment Construction

[0040] In the prior art, whether it is electromagnetic induction wireless charging or magnetic resonance wireless charging, its working radius is usually only between a few centimeters and tens of centimeters. For some large household appliances, such as refrigerators, when using any of the above wireless charging methods to supply power to the electrical devices inside the household appliance, due to the limited working radius, it is difficult to cover all areas inside the household appliance with electromagnetic signals.

[0041] In the embodiment of the present invention, a repeater is set within the coverage area of ​​the electromagnetic signal emitted by the wireless power supply device, and the electromagnetic signal emitted by the wireless power supply device is transmitted through the repeater, which can expand the working radius of the wireless power supply device and expand the coverage of the electromagnetic signal scope.

[0042] In order to make the above objects,...

Abstract

A household electrical appliance comprises a wireless power supply device, at least one repeater and a power utilization device. The wireless power supply device emits an electromagnetic signal when power-on; the repeater is arranged in the coverage range of the electromagnetic signal emitted by the wireless power supply device, and transmits the electromagnetic signal when receiving the signal; and an electromagnetic signal receiver is arranged in the power utilization device, and generates current to supply power to the power utilization device when the electromagnetic signal is detected. Thus, the working radius of the wireless power supply device can be increased.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a household appliance. Background technique [0002] With the continuous development of the electronics industry, more and more manufacturers pay attention to wireless charging technology. When charging, there is no need to use wires to connect with electronic products, which can bring better user experience to users. [0003] Wireless charging technology can generally be divided into electromagnetic induction wireless charging, magnetic resonance wireless charging, radio wave wireless charging and electric field coupling wireless charging. In the prior art, widely used wireless charging technologies include electromagnetic induction wireless charging and magnetic resonance wireless charging. [0004] The basic principle of electromagnetic induction wireless charging is the principle of electromagnetic induction. A primary coil is provided at the transmitting end and a seco...
