Control method of bidirectional radio frequency water heater and water heater

Abstract

The invention relates to a control method of a bidirectional radio frequency water heater and the water heater. The water heater comprises a water heater control unit and a remote control terminal which can be in communication connection with the water heater control unit. The control method comprises the steps that the remote control terminal is in communication connection with the water heater control unit through a radio frequency communication module, and data transmission is conducted once every set time after communication is established. The radio frequency communication module obtains the current running state of the water heater from the water heater control unit every T1 time, and running parameters, displayed on a display screen of the remote control terminal, of the water heater are refreshed. According to the control method of the bidirectional radio frequency water heater provided by the invention, effective bidirectional communication is achieved, the running state of the water heater can be displayed on the remote control terminal, good use experience is brought to a user, meanwhile, power consumption is reduced to the maximum extent, and the service time of a battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method of a two-way radio frequency water heater and the water heater. Background technique [0002] At present, most of the solar heat pump water heaters on the market are operated by wire controllers. Since wire controllers need to arrange wire grooves in the wall before installing the water heater, or plan wire grooves in the wall before building decoration and construction, it is convenient for installation, which brings a lot of inconvenience. After the renovation, the solar heat pump water heater is installed again, and the wire controller communication line can only be placed outside, which not only affects the overall visual effect of the building, but also has certain safety hazards. Therefore, we propose to use the remote control instead of the wire controller. In addition, long-distance wiring is susceptible to external environmental interference...

Problems solved by technology

[0002] At present, most of the solar heat pump water heaters on the market are operated by wire controllers. Since wire controllers need to arrange wire grooves in the wall before installing the water heater, or plan wire grooves in the wall before building decoration and construction, it is convenient for installation, which brings a lot of inconvenience. After the renovation, the solar heat pump water heater is installed again, and the wire controller communication line can only be placed outside, which not only affects the overall visual effect of the building, but also has certain safety hazards. Therefore, we propose to use the remote control instead of the wire controller

In addition, long-distance wiring is susceptible to external environmental interference such as lightning strikes, and is easily bitten by small animals or eroded by corrosive liquids

Once the communication fails, it may cause safety hazards in the water heater, such as the water temperature is too high and the user is scalded, etc.

[0003] Most water heater remote controllers on the market generally use infrared remote control or 2.4GHZ communication mode, which can only realize the one-way control function, and cannot display the running status of the water heater in real time. Users cannot grasp the operating parameters of the water heater well, which is not conducive to users water heater control

Moreover, using infrared remote control or 2.4GHZ communication method consumes a lot of power, the remote control distance is also quite limited, and the ability to penetrate walls is weak. It is very inconvenient to live in a living space with a large facing area and many walls, and it is impossible to achieve long-term effective communication.

For the existing two-way communication remote control, the power consumption is generally relatively large, and the power loss is serious. The battery even needs to be replaced once a month. Users need to replace the battery frequently, which seriously affects the user experience.
