Problems solved by technology

At this time, in the process of burning the combustible gas, the combustible gas and the combustion-supporting gas are consumed together, but because of the lack of combustion-supporting gas, the combustion efficiency of the combustible gas will be reduced and the combustible gas cannot be fully combusted, and the remaining combustible gas is directly discharged from the water heater. Discharge into the user's room, thereby reducing the safety of the water heater and endangering the personal and property safety of the user

Embodiment Construction

[0031] A combustion efficiency control method and device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] To make the description clearer, a water heater that heats water by burning combustible gas is taken as an example for description. Such as figure 1 As shown, when the user uses the water heater 1, the switch of the water heater is turned on (not shown in the figure), and the temperature of the water outlet during use is set; the valve 2 arranged on the gas pipe 3 is opened, and combustible gas is introduced into the water heater 1, The main ...

Abstract

The invention discloses a method and a device for controlling burning efficiency. The method and the device for controlling burning efficiency belong to the field of burning equipment and are designed for solving the problem that effective controlling of burning efficiency cannot be realized in the prior art. The method for controlling burning efficiency includes detecting concentration of gas to be tested at an exhaust port; judging whether the concentration exceeds the preset concentration value or not; improving rotation speed of a fan if the concentration exceeds the preset concentration value; keeping the fan working normally at the constant rotation speed if the concentration is within the preset concentration value; judging whether the rotation speed exceeds the preset maximum rotation speed or not; keeping the fan rotating at the current speed and switching off a main valve, a sectional valve and a proportional valve for inputting combustible gas if the rotation speed exceeds the preset maximum rotation speed; and detecting the concentration of the gas to be tested at the exhaust portion if the rotation speed is within the preset maximum rotation speed.

Description

technical field [0001] The invention relates to the field of combustion equipment, in particular to a method and device for controlling combustion efficiency. Background technique [0002] Electrical products that burn combustible gas for heating have become indispensable in home life, such as water heaters, etc., but because combustible gas needs to be burned, and the combustible gas may be toxic, it poses a certain threat to personal and property safety. Therefore, how to ensure higher safety performance has always been the focus of manufacturers' research. [0003] In the prior art, taking a water heater as an example, a combustible gas is continuously introduced and burned, so as to heat the water passed into the water heater for use by users. When the user uses it, because the combustible gas is continuously fed into the water heater, the ratio of the combustible gas and the combustion-supporting gas will be out of balance, that is, the combustible gas is excessively s...
