Abstract

A water storage type electric water heater capable of controlling power on and off by utilizing infrared induction comprises a shell, an upper liner, a lower liner, a water outlet pipe, a temperature sensor, a heating pipe and a control device, wherein the temperature sensor and the heating pipe are connected with the control device; the lower liner is provided with a cold water inlet pipe and a blow-off pipe, the control device comprises a power panel, a display control panel and an infrared receiving head, and the display control panel is connected with the power panel; the temperature sensor and the heating tube are connected with the power panel, and the infrared receiving head is connected with the power panel. By adopting the structure, when people use the electric heating infrared receiving head, the infrared receiving head transmits a signal to the power panel when detecting a person, and the power panel cuts off the power supply, so that the electric heating infrared receiving head is used by people in a state without electricity, potential safety hazards are eliminated, and personal safety is ensured; when people leave, the infrared receiving head transmits signals to the power panel, and then the power is switched on.

Description

A storage-type electric water heater capable of using infrared induction to control power on and off

technical field

The invention relates to an electric water heater, in particular to a storage type electric water heater.

Background technique

In the current prior art, a water storage type electric water heater includes a casing, an upper tank, a lower tank, a water outlet pipe, a temperature sensor, a heating pipe and a control device, and the temperature sensor and the heating tube are connected to the control device; The cold water inlet pipe and the sewage pipe; the outlet pipe is provided with an anti-electric wall. Existing problem is: adopt the measure of passive electric shock prevention, people use under electrified situation, there is potential safety hazard.

Contents of the invention

The object of the present invention is to provide a water storage electric water heater which can control the power on and off by means of infrared induction, which can automatically cut off the power supply when people use it, and automatically turn on the power when people leave.

The present invention is achieved in the following way: a water storage electric water heater capable of controlling power on and off by means of infrared induction, including a casing, an upper tank, a lower tank, a water outlet pipe, a temperature sensor, a heating pipe and a control device, a temperature sensor and a heating pipe It is connected with the control device; there are cold water inlet pipes and sewage discharge pipes on the lower tank, and the control device includes a power board, a display control board and an infrared receiving head,

The display control board is connected to the power board; the temperature sensor and the heat pipe are connected to the power board, and the infrared receiving head is connected to the power board.

The storage-type electric water heater capable of using infrared induction to control power on and off is special in that: the power board includes a single-chip microcomputer and a relay, the relay is connected to the heating pipe, and the temperature sensor is connected to the single-chip microcomputer.

The water storage type electric water heater capable of using infrared induction to control power on and off is special in that: the power board includes a single-chip microcomputer and a thyristor, the thyristor is connected to the heating tube, and the temperature sensor is connected to the single-chip microcomputer.

The present invention is a water storage type electric water heater that can use infrared induction to control power on and off. Due to the adoption of such a structure, when people use it, when the infrared receiving head detects a person, the signal is transmitted to the power board, and the power board cuts off the power supply. So that people can use it in the state of no electricity, eliminating potential safety hazards and ensuring personal safety; when people leave, the infrared receiving head transmits the signal to the power board, and then the power is turned on.
