Wireless transmission-based data processing system and household electrical appliance

Abstract

The invention is suitable for a household electrical appliance and provides a wireless transmission-based data processing system. The system includes an external device disposed outside the householdelectrical appliance, and a built-in device disposed inside the household electrical appliance. The external device includes a first signal processing unit and a first transmission unit which are interconnected; the built-in device includes a second signal processing unit and a second transmission unit which are interconnected; the first transmission unit at least includes a first electromagneticinduction coil, and the second transmission unit at least includes a second electromagnetic induction coil; the external device transmits target data to the built-in device through the first electromagnetic induction coil, and receives first feedback data from the built-in device; the built-in device receives the target data through the second electromagnetic induction coil, and transmits the first feedback data to the external device; and the built-in device can also convert electrical energy into electromagnetic radiation through the second electromagnetic induction coil, and the first electromagnetic induction coil can receive the electromagnetic radiation and converts the electromagnetic radiation into the electrical energy to supply power for the external device.

Description

technical field [0001] The invention belongs to the field of home appliances, in particular to a data processing system based on wireless transmission and a home appliance. Background technique [0002] Because of its high intelligence, household appliances are widely used in people's daily life, bringing great convenience to users' lives. [0003] In the prior art, household appliances often include a shell, inside the shell is a processing mechanism such as a control panel and other instructions and information of the equipment, and outside the shell is often a mechanism that can be directly operated by the user, such as a control panel. During normal operation, the internal and external parts need to exchange data, communicate, etc. The traditional method is to connect the two electrically to achieve communication. In this way, holes need to be drilled on the shell, which will affect the appearance on the one hand. On the other hand, more processes are also required. An...

Problems solved by technology

[0003] In the prior art, household appliances often include a shell, inside the shell is a processing mechanism such as a control panel and other instructions and information of the equipment, and outside the shell is often a mechanism that can be directly operated by the user, such as a control panel. During normal operation, the internal and external parts need to exchange data, communicate, etc. The traditional method is to connect the two electrically to achieve communication. In this way, holes need to be drilled on the shell, which will affect the appearance on the one hand. On the other hand, more process

Another method is to set up Bluetooth in the external mechanism to achieve internal and external communication, but because the shell separates the two parts, the external mechanism cannot be powered by the control board, and an additional power supply is required to ensure its normal operation. Because of the addition of Bluetooth and power supply, the production cost has increased a lot, and the cost will inevitably be reflected in the price of the product. For consumers, the practicability is not very high.
