Problems solved by technology

Although the hot water circulation device of this structure can realize the function of zero cold water, there is such a defect: the water of the gas water heater is supplied to the user after passing through the electric water heater, and the heat will be dispersed, resulting in the water temperature not being very high, which cannot meet the needs of the user. Some requirements; in addition, because the water of the electric water heater comes through the gas water heater, when the gas water heater cannot be used normally, the above-mentioned hot water circulation device cannot provide hot water to the user

Abstract

The invention relates to a hot water circulation device and a control method thereof, wherein the hot water circulation device comprises a controller, a cold water pipe, a flow sensor, a circulating water pipe, a gas water heater, an electric water heater, a water pump, a first temperature sensor, and a second temperature sensor , the first on-off valve and the second on-off valve. The hot water circulation device of the present invention can be effectively utilized to realize that users can obtain hot water at a higher temperature, use hot water immediately, and use hot water uninterruptedly.

Description

technical field [0001] The invention relates to the field of hot water equipment, in particular to a hot water circulation device and a control method thereof. Background technique [0002] Existing hot water circulation devices usually include a gas water heater, a circulation pump, a circulating water pipe and an electric water heater. The electric water heater is provided with a water inlet and a water outlet. The water outlet is connected with the water inlet of the electric water heater, and a plurality of water outlets are arranged on the circulating water pipe. Although the hot water circulation device of this structure can realize the function of zero cold water, there is such a defect: the water of the gas water heater is supplied to the user after passing through the electric water heater, and the heat will be dispersed, so that the water temperature will not be very high, which cannot meet the needs of the user. Some requirements; In addition, because the water o...
