Embodiment 2

[0102] A control method for a heating gas water heater, including a control method in which the bathroom mode and the heating mode operate simultaneously. In this embodiment, the bathroom mode is first turned on, and then the heating mode is turned on, and the bathroom mode and the heating mode coexist. The main steps are as follows :

[0103] S100: The water heater is in the standby state when it is powered on, turn on the bathroom mode, set the bathroom water temperature T0, and turn on the water equipment;

[0104] S101: The inlet water temperature sensor 25 detects the inlet water temperature, the first water flow sensor 26 detects the inlet water flow rate, and the controller judges whether the starting conditions of the combustion system 2 are met at the same time according to the values ​​detected by the inlet water temperature sensor 25 and the first water flow sensor 26 ;

[0105] S102: If the starting conditions of the combustion system 2 are not met, the combustion...

Embodiment 3

[0114] A control method for a heating gas water heater, including a control method for simultaneous operation of the heating mode and the bathroom mode. In this embodiment, the heating mode is first turned on, and then the bathroom mode is turned on. The heating mode and the bathroom mode coexist. The control method is as follows :

[0115] S200: The water heater is powered on and is in the standby state, the water equipment is turned off, the controller controls the second two-position two-way valve 20 to close, and the heating mode is turned on, the controller makes the first two-position two-way valve 22 open, the first water pump 10 starts, and water enters The temperature sensor 25 detects the inlet water temperature, the first water flow sensor 26 detects the inlet water flow, and the controller judges whether the starting conditions of the combustion system 2 are met at the same time according to the values ​​detected by the inlet water temperature sensor 25 and the firs...

Embodiment 4

[0125] A method for controlling a heating gas water heater, including a method for controlling a bathroom mode, the steps of which are mainly as follows:

[0126] S300: The water heater is in the standby state when it is powered on, turn on the bathroom mode, set the bathroom water temperature T0, and turn on the water equipment;

[0127] S301: The inlet water temperature sensor 25 detects the inlet water temperature, the first water flow sensor 26 detects the inlet water flow, and the controller judges whether the starting conditions of the combustion system 2 are met at the same time according to the values ​​detected by the inlet water temperature sensor 25 and the first water flow sensor 26 ;

[0128] S302: If the starting conditions of the combustion system 2 are not met at the same time, do not start and return to step S301;

[0129] S303: If the start-up condition of the combustion system 2 is met, the controller controls the start-up of the combustion system 2;

Abstract

The invention discloses a heating gas water heater. The heating gas water heater comprises a shell, and a heat exchange system and a combustion system are arranged in the shell. The heat exchange system is provided with a water inlet end and a water outlet end, the water inlet end communicates with a water inlet formed in the shell through a main water inlet pipeline, and a first water flow sensorand a water inlet temperature sensor are arranged on the main water inlet pipeline; a bathroom water outlet, a heating water outlet and a heating water return opening are further formed in the shell,the heating water return opening communicates with the main water inlet pipeline through a heating water return pipeline, a first water pump used for heating water circulation is arranged on the heating water return pipeline, and a first three-way valve is arranged at the water outlet end; and the bathroom water outlet is connected with one port of the first three-way valve through a bathroom water pipeline, and the heating water outlet is connected with the other port of the first three-way valve through a heating water pipeline. According to the gas water heater, a bathroom can be heated while a user takes a bath, the situation that the user is in a low-temperature environment in the bath process is avoided, and the bath experience of the user is improved.

Description

technical field [0001] The present invention relates to the technical field of gas water heaters, and more specifically, to a heating gas water heater and a control method thereof. Background technique [0002] When users bathe in winter, the temperature of the bathroom is low, a large amount of water vapor is generated during the bathing process and ventilation must be maintained, and the heating function of the current gas water heater cannot be used at the same time as the bathroom function, which greatly affects the bathing experience of the user. Therefore, there is an urgent need to develop a gas water heater that can operate simultaneously with bathroom and heating to ensure that users have a comfortable bath. Contents of the invention [0003] The present invention provides a heating gas water heater to overcome the problems in the prior art that the heating function of the gas water heater cannot be used simultaneously with the bathroom function, and the temperatu...
