Control method for gas burner water heater and gas water heater using the method

Abstract

The invention relates to a control method of a gas heater, which comprises a heater body. The invention also comprises at least two remote control units. The control method comprises the following steps: the step 1: an operation token and a distribution module are arranged in a communication module; the step 2: a master control module judges whether a local control order is input into an operation control module, if the local control order is input, the master control module receives and executes the local control order sent by the operation control module, and the step 2 is cycled; and if the local control order is not input, the next step is executed; the step 3: the master control module judges whether a primary remote control order of the operation token is input or not, if the primary remote control order is input, the step 4 is executed; if not, a distribution module distributes the operation token to the remote control unit that applies for the operation token first according to the chronological sequence and a first receiving module receives the primary remote control order of the remote control unit, and finally, the step 3 is cycled; the step 4: the master control module executes the primary remote control order of the operation token and a timer is opened; after the timing time of the timer becomes due, the operation token is released, and the step 2 is back. The invention has the advantages that the multipoint control method to the heater is realized and the collision problem of the multipoint control is solved.

Description

technical field [0001] The invention relates to a control method of a gas water heater and a gas water heater using the method. Background technique [0002] Gas water heaters are used to heat water quickly by burning gas, and are widely used in daily life. Considering the safety problems caused by gas leakage, gas water heaters are generally not installed directly in the bathroom, but installed in the kitchen or other places away from the bathroom, which brings a trouble to the user, that is, the user is in the shower or away from the water heater. Where there is no water, there is no way to adjust the water temperature or control the heater. The earlier ordinary gas water heaters were mostly controlled by wires. If the user needs to control the water heater in the bathroom or in a place far away from the installation location of the gas water heater, it is necessary to arrange a long distance of wires, which not only increases the cost, but also easily causes electric sho...

AI Technical Summary

Problems solved by technology

[0004] But above-mentioned wireless remote control device is used to control water heater and mostly is one-way one-to-one control mode, and promptly remote controller has only one, and, one-to-one control mode has limited the scope of use of remote controller, along with modern family water heater It is widely used. In addition to bathrooms, water is often supplied by water heaters in other places. In this way, it is necessary to implement a multi-point control remote control device so that users who use water in different places can perform remote wireless remote control on water heaters. , convenient for daily use; in addition, the above-mentioned patent documents do not mention how to solve the conflict between the control module on the water heater body and the remote control when they are operated at the same time

[0005] In addition, the above-mentioned patent documents mentioned that when using a wireless remote control device to control the water heater, the user can only send control signals through the remote control, but cannot know the current working status of the water heater through the remote control, and often has a certain degree of blindness when adjusting.
