Water heater rapid-heating and thermostatic-controlling device

Abstract

A water heater rapid-heating and thermostatic-controlling device comprises a water heater housing, wherein a water storage cavity is arranged in the water heater housing; a heating device is fixedly arranged at the right end of the water storage cavity; a sealing block is arranged at the lower end of the water storage cavity in an up-down movable manner; a water level sensor is fixedly arranged atthe left end of the water storage cavity; a water inlet pipe is arranged at the lower end of the water heater housing and communicates with the water storage cavity; and a water inlet valve is arranged in the water inlet pipe. The water heater rapid-heating and thermostatic-controlling device is simple in structure and convenient to operate; when the water storage cavity is added with water, theheating device switches to the high-power heating mode according the water weight, so that the rapid supply of hot water in the water storage cavity can be achieved; when the water storage volume of the water storage cavity is higher than the water level of the water level sensor, the heating device switches to the low-power heating mode through the thermal expansion and contraction of a temperature measuring liquid in a temperature measuring box; and when the water temperature of the water storage cavity drops to the minimum temperature, the heating operation is performed by low power, so that the water in the water storage cavity can be thermostatically controlled by low power, and the consumption of electric energy can be reduced.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a rapid heating and constant temperature device for a water heater. Background technique [0002] During the use of the water heater, when the hot water in the water tank is transported outward, the water tank is constantly replenished with cold water and heated at the same time. Due to the mixing of cold water and hot water, the water temperature drops, which affects people's experience of using hot water. As a result, at the same time, it is necessary to reheat the hot water in the water tank, which takes a lot of time. At the same time, it needs to consume a lot of power to use the constant temperature of the water, and the water in the water tank cannot be heated in time, which affects the use. In order to solve the above problems, The present invention has been proposed. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned technologies, the...
