There are flow notches 924 and tapered grooves 926 (see FIGS. 2-4 ).

The working principle of the water heater of the utility model is as follows: when the water heater is required to generate steam, the situation is that the temperature in the bathroom is low, and the steam is used for preheating first, and the knob of the water flow regulating valve 9 is rotated by a certain angle, even if it is in the When the opening is 0, the water hole 922 of the spool 921 is completely blocked from the water inlet and outlet pipes, but there is a gap 924 on the side of the water inlet 923 of the water hole 922, and there is a tapered small groove 926 on the side of the water outlet 925. , water can enter the water hole 922 from the gap 924, and flow from the tapered small groove 926 to the water inlet pipe 41 of the heat exchange box 4 through the water hole 922. Since the tapered small groove 926 has a small diameter, the water valve 92 The overflow opening is much smaller than the overflow of the water temperature regulating valve in the water heater of the known technology, and the amount of water passing through the water heater is controlled, so the amount of water flowing through the water heater is much less than the amount of water in the high temperature state of the known water heater during a normal shower. But the firepower is not reduced, a small amount of water is heated and vaporized in the water tank, and becomes water vapor and splashes out from the hot water outlet, and steam is generated to preheat the bathroom.

In order to ensure the safety in use, a safety trap 106 can be installed on the right side of the above-mentioned diaphragm chamber 101 .

The working principle of the water heater in the known technology is as follows: when using the water heater, open the installed liquefied gas main switch, water inlet valve, and water outlet valve, and after the water flows through the water temperature regulating valve 11, the water flow resistance is around the diaphragm chamber 101 of the water-gas linkage valve 10 A water pressure difference is formed on both sides, and the water diaphragm expands to the left, pushing the valve stem 102 to move to the left, thereby pushing the piston 103 to move to the left, the spring 104 shrinks, and the valve port is opened. The switch in the ignition mechanism is closed. On the one hand, the high-voltage electric generator 34 in the pulse electric ignition mechanism 3 initiates a circuit action. On the other hand, the solenoid valve 6 is energized once and the intake valve 6 is opened. The casing 1 on the burner 2 generates high-voltage discharge, the indicator light 33 is on, the combustible gas is ignited and burned, the flame detection needle 35 is connected with the casing 1 of the burner 2 through the flame, and the solenoid valve 6 is energized to maintain the voltage. The high-voltage discharge stops, the indicator light 33 goes out, and the heat energy is passed to the cold water through the water pipe and the heat transfer sheet on the heat exchanger 4; when the water outlet valve or the water inlet valve is closed, the pressure difference between the left and right sides of the water diaphragm in the diaphragm chamber 101 disappears rapidly , the piston 103 moves to the right under the action of the spring 104, the intake valve port is closed, and the gas passage is cut off. At the same time, the valve stem 102 moves to the right, pushing the water diaphragm to reset and the shift fork 105 to move to the right, so that the switch is disconnected, and the solenoid valve 6 is de-energized Reset, cut off the gas passage, the flame goes out, and the water heater stops working.

The flameout protection principle of the water heater is as follows: if the flame goes out accidentally, the flame detection needle 35 and the shell 1 of the combustion chamber 2 cannot be electrically connected through the flame, the solenoid valve 6 loses the maintenance voltage and resets, and the gas passage is automatically cut off to ensure safe use .

The oxygen-deficient protection principle of the water heater is as follows: in the event of oxygen-deficient combustion, the flame will be elevated, and the flame detection needle 35 and the shell 1 of the burner 2 cannot be electrically connected through the flame, and the solenoid valve 6 will be reset when the power is off, and the gas will be cut off automatically. access, the fire is extinguished, and the water heater stops working to ensure personal safety.

Wherein the gas regulator 7 and the water temperature regulating valve 9 can allow the user to adjust the flow rate of gas and water respectively, control each other, cooperate with each other to adjust, and then the ideal hot water temperature can be obtained.

The utility model is connected with the remote control driving mechanism and installed on the water heater, and receives a specific wireless remote control signal, which can realize the water temperature adjustment and the split water heater separated from the fuselage, that is, the water heater is installed outside the bathroom, and the bather in the bathroom can adjust it at will with the remote control The water temperature in the bathroom is safe and convenient for users, helping people to freely and freely "bath" in the modern bathroom.
