Control method of water heater

Abstract

The invention discloses an active non-contact control method of a water heater. The water heater comprises a water heater body, a multi-stage heating mode controller in the water heater body, a human body infrared induction module and a human body infrared receiving module, wherein the human body infrared receiving module is arranged on the water heater body and connected with a control circuit inside the water heater body through a wireless module or a serial port; data are transmitted between the human body infrared induction module and the human body infrared receiving module through a wireless module or a serial port, and corresponding control instructions are received through the human body infrared receiving module and transmitted to the control circuit inside the water heater body, so that the temperature of the water heater can be controlled, and not only are the safety and the comfort degree of a human body during usage of the water heater improved, but also the service life of the water heater is prolonged.

Description

【Technical field】 [0001] The invention relates to a control method for a water heater. 【technical background】 [0002] At present, most water heaters usually use buttons or knobs to complete the relevant control of the water heater. The buttons or knobs are all set on the water heater, but with this control method, the distance between the water heater and people is very close, and in the humid environment of the bathroom, it is easy. Risk of electric shock. During the bathing process, related adjustments are made to the water heater. Due to the residual water on the hands, when the hands are in direct contact with the buttons or knobs of the water heater, it is also easy to cause the risk of electric shock. In the environment of bathing in the bathroom, people's vision is not good, which will make it difficult to touch the buttons or knobs. [0003] Although there are also infrared devices on the market to control the related actions of water heaters, the current way ...

Problems solved by technology

However, in the above-mentioned method of using infrared to control the operation of the water heater, the main body of specific perception is the infrared device, that is, passive control, not the human body itself. Controlling the water heater sometimes even causes great inconvenience when people use the water heater

[0004] In addition, the heating power of existing water heaters is relatively single, and generally there is only one heating power. When the water in the water heater is heated to a certain temperature, the heating is stopped, and when the water temperature drops to a certain temperature, for instant water heaters, Generally, the power of the electric heater is relatively large. Once the heating water starts to heat up quickly, the electric heater will be automatically turned off due to the short heating time. For the inner tank of the water heater, the rapid and sharp temperature rise will cause the inner tank to expand rapidly, reducing the service life of the inner tank, and because the water temperature is not constant, the human body will feel hot and cold when bathing, and it cannot be adjusted according to the body's temperature. Subjective feeling to adjust the heating power of the water heater, thereby adjusting the water temperature of the water heater
