Operation method of gas water heater with function of prompting that liquefied petroleum gas is about to be burnt out

Abstract

The invention discloses an operation method of a gas water heater with a function of prompting that liquefied petroleum gas is about to burn out. The water heater comprises a water quantity sensor; a water outlet temperature sensor is arranged at the water outlet end of the water heater; a water inlet temperature sensor is arranged at the water inlet end of the water heater; the current actual output heat Qs of the water heater is calculated through data collected by the water inlet temperature sensor, the water outlet temperature sensor and the water volume sensor; the current detected output heat Qr of the water heater is calculated and obtained by controlling the frequency of the rotating speed of a fan motor of the air amount required by combustion through the water heater or judging the current of a gas proportional valve for controlling the gas amount; when Qr is larger than Qs by a certain difference value and lasts for a certain time, low gas supply pressure caused by insufficient vaporization capacity of the liquefied petroleum gas can be judged. According to the gas water heater, liquefied petroleum gas in a household steel cylinder is more fully burnt out, preparation for replacing the steel cylinder is prompted to be made in time, the popularization rate and economical efficiency of the gas water heater are improved, and the use comfort and convenience are improved.

Description

technical field [0001] The invention relates to the technical field, in particular to an operating method of a gas water heater with a function of prompting that liquefied petroleum gas is about to be burned. Background technique [0002] In the prior art, the use of liquefied petroleum gas gas water heaters often causes insufficient vaporization of liquefied petroleum gas in winter due to low ambient temperature, thus causing the gas water heaters to fail to work normally. [0003] And in the process of use, there will be shutdown faults and error reports, which will cause great confusion to users. At the same time, there will still be more liquefied petroleum gas cylinders that have been replaced. The liquefied petroleum gas can still be maintained for a long time under lower load conditions. A case of time burning. [0004] Therefore, how to make the liquefied petroleum gas gas water heater fully burn up the liquefied petroleum gas in the household steel cylinder, and pr...
