Water heater outlet water temperature control device and control method thereof

Abstract

The invention discloses a water heater outlet water temperature control device and a control method thereof. The device comprises a water heater shell, a temperature controller and a heat source selection device, wherein the temperature controller and the heat source selection device are arranged outside the water heater shell, an insulating plate is arranged on the outer side of the water heatershell, a sealing cavity is formed in the water heater shell, a proportional flow control mechanism is arranged in the sealing cavity, the proportional flow control mechanism internally comprises a core valve and left and right electromagnetic soft irons installed on the two sides of the core valve, left and right coils are evenly wound on the left and right electromagnetic soft irons, the water heater shell and the valve seat are provided with a water inlet and a water outlet, and the water inlet and the water outlet are connected through a hose. According to the device, a heat source is automatically selected through the set temperature, after the heat source is selected, the water outlet temperature of the water outlet controls the current and voltage of the left coil and the right coilthrough the temperature controller, and therefore the effect that the water outlet temperature is constant is achieved by controlling movement of the core valve.

Description

technical field [0001] The invention belongs to the technical field of water heater control, and in particular relates to a water heater outlet temperature control device and a control method thereof. Background technique [0002] With the continuous progress of the times, water heaters have become one of the indispensable devices in people's lives. After years of development, water heaters currently on the market include solar water heaters, gas energy water heaters, electric water heaters, and air energy water heaters. etc., the hot water port and the cold water port in the water heater are connected through the water mixing valve, the cold and hot water are mixed at the water mixing valve, and discharged through the water outlet for the user to use. , the temperature of the outlet water should not be adjusted. During the bathing process, the water temperature will be uneven, cold and hot. This kind of water temperature change will make people feel uncomfortable, and it is...
