Problems solved by technology

[0002] At present, the gas water heaters with DC speed-adjustable fans used in the market generally control the variable current by pre-setting the fan speed curve. This method requires pre-sampling the whole machine and then determining the matching between the fan speed or current and the combustion of the whole machine. relationship, when the difference of the fan itself is large, the matching relationship of the curve will have a large deviation, which cannot optimally meet the requirements of combustion stability and working conditions; another control method is to use the preset wind speed curve to control each load Compensation for the wind speed at different stages, this method is cumbersome, and a large number of tests need to be done in the early stage of the design to confirm and improve, and the requirements for the consistency of the fan are relatively high

Embodiment 1

[0025] Embodiment 1 of the present invention provides a burner capable of detecting the pressure of the air chamber, such as figure 1 As shown, it includes a burner housing 1, one or more fire row groups 2, and a pressure detection assembly. The inside of the burner housing 1 is a combustion chamber 11. In the chamber 11, one side of each fire row group 2 is provided with an ejection port 21, and the burner housing is provided with an air inlet 12, and the burner housing 1 is respectively provided with an air inlet 12 The primary air chamber 3 communicates with the secondary air chamber 4, the primary air chamber 3 communicates with the injection port 21, the secondary air chamber 4 communicates with the combustion chamber 11, and the pressure detection assembly is arranged on the burner housing 1 is used to detect the pressure of primary air chamber 3 and secondary air chamber 4.

[0026] Wherein, one side of the burner housing 1 is also provided with a gas inlet 13 correspo...

Embodiment 2

[0041] Embodiment 2 of the present invention provides a pressure-following control method for controlling the air volume of a gas water heater, which is applied to a gas water heater. The gas water heater includes a burner capable of detecting the pressure of the air chamber as described in Embodiment 1. The method is as follows:

[0042] According to the instantaneous gas secondary pressure P 3 and the preset theoretical gas secondary pressure P 3 ’ Whether it is consistent, determine whether the gas water heater is in working condition.

[0043] In the working state of the gas water heater, according to the inlet air pressure P 0 Respectively with the current primary air chamber pressure P 1 , Secondary air chamber pressure P 2 The difference determines the first instantaneous pressure difference ΔP 0-1 , the second instantaneous pressure difference ΔP 0-2 ; According to the first instantaneous pressure difference ΔP 0-1 and the second instantaneous pressure difference...

Abstract

The invention discloses a burner capable of detecting the pressure of an air chamber and a control method thereof, which comprises a burner housing, one or more fire row groups, and a pressure detection assembly, one or more fire row groups are arranged in the combustion chamber, The burner housing is respectively provided with a primary air chamber and a secondary air chamber which communicate with the air inlet, the primary air chamber communicates with the injection port, and the secondary air chamber communicates with the combustion chamber. Detect the pressure of the primary air chamber and the secondary air chamber; the present invention can adjust in real time according to the combustion feedback to make the system reach the best combustion condition, and adjust the speed of the fan by adaptively adjusting the combustion, even if the difference of the fans is large It can also be adjusted in real time to meet the comfort and stability requirements of the whole machine.

Description

technical field [0001] The invention belongs to the technical field of gas water heaters, and in particular relates to a burner capable of detecting the pressure of an air chamber and a control method thereof.
