Embodiment 1

[0030] The present invention provides such figure 1 A method for controlling a gas water heater with a storage tank is shown, comprising the following steps:

[0031] S1. After confirming that there are no flammable and explosive items around the water heater, power on the water heater;

[0032] S2. After the water heater is powered on, the sensor function self-inspection module performs a self-inspection on all the sensors of the water heater to detect whether each sensor is normal. If any abnormality is found, the alarm unit will alarm;

[0033] S3. After the self-test of the sensor shows that everything is normal, the harmful gas detection unit will detect harmful gas in the surrounding environment of the water heater. If an abnormality is found, the alarm unit will give an alarm, and the ambient temperature sensor will detect the external temperature. When the temperature is 71°C temperature, the alarm unit gives an alarm, and the harmful gases detected by the harmful gas...

Abstract

The invention discloses a method for controlling a fuel gas water heater with a storage tank. The method for controlling the fuel gas water heater with the storage tank comprises the following steps that the water heater is electrified; after the water heater is electrified, self-inspection is conducted on all sensors of the water heater by a sensor function self-inspection module, it is detectedwhether each sensor is normal or not, and if abnormalities are found, an alarm is given by an alarm unit; and after self-inspection of the sensors is completed and it is shown that everything is normal, harmful gas detection is conducted on the surrounding environment of the water heater by a harmful gas detection unit, if abnormalities are found, an alarm is given by the alarm unit, and the external temperature is detected by an environment temperature sensor. According to the method for controlling the fuel gas water heater with the storage tank, through data of comparison between the fuel gas amount consumed by heating of water of the same amount and the past normal amount consumed, it is judged whether a flammable vapor incident occurs; and a breakdown caused by abnormalities of a flammable vapor (FV) sensor can be avoided. According to the method for controlling the fuel gas water heater with the storage tank, the fuel gas amount and water amount are controlled accurately, data obtained through the method are more accurate, and probability of mistaken measuring is lowered.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to a method for controlling a gas water heater with a storage tank. Background technique [0002] In gas furnace systems, various types of sensors are commonly used to provide information that controls the operation of the system. For example, in a domestic water heater, an immersion sensor can be used inside the tank to monitor the water temperature. Commercial water heaters typically run at a higher temperature than residential units and may have a pair of immersion sensors, one at the top and one at the bottom of the tank. Bottom and top sensors are usually monitored relative to a set temperature and temperature range. The heating is usually stopped when the water temperature reaches the set temperature and starts when the temperature falls below the temperature range. Water heaters are also often equipped with flammable vapor (FV) sensors to detect the presen...
