Description

TECHNICAL FIELD

[0001] The present application relates to the field of electric water heaters, in particular to a single-inlet double-outlet waterway structure and an electric water heater. BACKGROUND

[0002] The patent with publication number CN214367965U is an electrically controlled double-outlet water faucet applied by the applicant, which comprises a vertical pipe, a threaded pipe, a water outlet arm, an electric control box, a circuit board arranged in the electric control box, a water outlet nozzle arranged on the water outlet arm, a thick / thin film heating tube, a heating tube body, a shell made of heat-conducting material, a preheating heat exchange tube, a water outlet connector, a top water distribution seat, a base, a cold water path electromagnetic valve and a hot water path electromagnetic valve. The heating tube body is arranged in the thick / thin film heating tube, and the spiral water guide groove and the thick / thin film heating tube form a heating water path. The preheating heat exchange tube is attached to the shell. The shell, the heating tube body, the thick / thin film heating tube, the water outlet connector, the top water distribution seat, the base and the preheating heat exchange tube form a water path main body, which is inserted into the vertical pipe. The water outlet connector is located in the water outlet arm and communicates with the water outlet nozzle. The connecting pipe on the water outlet arm is connected to the upper end of the vertical pipe. The threaded pipe is connected to the lower end of the vertical pipe.

[0003] The electrically controlled double-outlet water faucet needs to be used in combination with an external host. The cold water path electromagnetic valve and the hot water path electromagnetic valve are used to control the on-off of the cold water path and the hot water path. The size of the water flow needs to be controlled by the external host.

[0004] The patent with publication number CN215806657U is an automatic throttle valve applied by the applicant, which is suitable for the field of electric water heaters and comprises a shell, a valve core, a motor, a flow sensor rotor, a first Hall element, a second Hall element and a positioning magnet. The shell is provided with a water inlet pipe, a water outlet pipe and a valve core cavity. In use, the dynamic sheet is rotated by the motor. The output shaft of the motor drives the positioning magnet to rotate in the process of rotation. The second Hall element can sense the position of the positioning magnet, so as to determine the rotation amplitude of the output shaft of the motor. Under normal circumstances, the first Hall element cooperates with the flow sensor rotor to obtain the water flow in the water inlet pipe in real time, so as to control the opening time of the valve core according to the need. Under normal circumstances, the motor will automatically reset. When the power is off and restarted, if the positioning magnet is not in the specified position, the second Hall element will continuously send a signal to the control center, so as to drive the output shaft of the motor to rotate until the positioning magnet moves to the specified position, thereby completing the reset after power failure.

[0005] The automatic throttle valve is used in the electric water heater. By controlling the relative angle of the dynamic valve sheet and the positioning valve sheet, the size of the water flow can be controlled, so that the electric water heater can independently control the water flow, without the need to be used in combination with an external host.

[0006] The user uses normal temperature water, and does not need to control the rotation amplitude of the motor output shaft to control the water flow, and the user can obtain water of a specific temperature, and only when the user needs hot water of a specific temperature, the water flow of the inlet water needs to be controlled, so that the water flow is matched with the power of the heating pipe in the electric heating water hole head, so that water of a specific temperature is obtained.

[0007] In the prior art, the flow sensor is arranged in the inlet water pipe, and the flow sensor needs to work as long as the faucet discharges water, whether it is normal temperature water or hot water that needs to be heated, which reduces the service life of the flow meter, and thus the prior art needs to be improved.
