Problems solved by technology

However, there are some defects in this prior art: due to the need to control the switching state of at least two solenoid valves to control the gas intake volume during ignition, its operation is relatively cumbersome; the solenoid valve is fully opened when the water heater is working, so it cannot It is necessary or set working conditions to adjust the size of the burning gas; for different solenoid valve switch states, the intelligent controller cannot automatically adjust the gas volume on the gas intake path; due to the simultaneous ignition and solenoid valve opening carry out, there is still the possibility of deflagration

Embodiment Construction

[0029] see figure 2 , is the principle block diagram of the explosion-proof gas water heater of the present invention. The water heater includes a main controller 110, a main solenoid valve 120, a proportional regulating solenoid valve 130, several segmented solenoid valves 140, a gas distributor 150 with several air inlet holes, and an igniter 160 matched with an ignition needle.

[0030] Wherein, the main controller 110 is electrically connected to the main solenoid valve 120, the proportional regulating solenoid valve 130 and several section solenoid valves 140, and controls and coordinates the switch states of the solenoid valves.

[0031] The main solenoid valve 120 is installed on the gas passage (not marked), and is the master switch of the entire gas passage. It can operate by receiving instructions from the main controller 110 to control the opening and disconnection of the gas passage.

[0032] The proportional regulating solenoid valve 130 is installed on the gas ...

Abstract

The present invention discloses explosion protection gas burning water heater. It contains main controller, lighter, blower fan and main solenoid valve, wherein said main solenoid valve located gas burning gateway for controlling gas burning gateway switch and connected to main controller, acting according to main controller instruction; said water heater also including: ratio regulation solenoid valve for regulating valve port opening to control gas burning gateway air inflow and having scheduled valve port opening in ignition; gas burning dispenser having at least two air inlet zone; solenoid valve with at least two section connected to main controller, and according to main controller instruction to act for controlling gas-fired inlet position.

Description

technical field [0001] The invention relates to the field of gas water heaters, in particular to an explosion-proof gas water heater. Background technique [0002] For consumers, the safety performance of gas water heaters is an extremely important quality measure. However, the safety performance of gas water heaters currently on the market is generally not high, and there are many potential safety hazards. There are many factors that affect the safety of gas water heaters. One of the more common phenomena is deflagration when starting up and ignition, and even explosion in severe cases, resulting in accidents and loss of people's lives and property. [0003] There are many reasons for the deflagration, such as the exhaust gas left before the gas water heater is turned on; the frequent opening after the start-up fails to ignite, and the accumulation of a large amount of gas in a short period of time, etc. [0004] In order to avoid deflagration, some technical solutions ha...
