Air heating equipment based on electric water heater

Abstract

The invention discloses air heating equipment based on an electric water heater. The air heating equipment based on the electric water heater comprises an electric water heater body and a heating box.The electric water heater body communicates with the heating box through a first hot water main pipe. The end, located in the electric water heater body, of the first hot water main pipe is fixedly connected with a fixed sleeve. A one-way valve is inserted into the fixed sleeve. Two sliding rods are symmetrically and fixedly connected to the top of the fixed sleeve. The sliding rod is slidably sleeved with a sliding block. One end of the sliding block is fixedly connected with the one-way valve. The sliding rod is sleeved with a first spring. The two ends of the first spring are fixedly connected with the sliding block and the fixed sleeve correspondingly. A hot water branch pipe is arranged in the electric water heater body. According to the air heating equipment based on the electric water heater, when hot water in the electric water heater is not used in time, heat returns into the heating box in time to achieve cyclic utilization of hot air, heat energy of the hot water is well utilized, and thus energy is saved.

Description

technical field [0001] The invention relates to the technical field of electric water heater equipment, in particular to a warm air equipment based on an electric water heater. Background technique [0002] Electric water heaters refer to water heaters that use electricity as energy for heating. They are one of the three major water heaters alongside gas water heaters and solar water heaters. ), instant heating type, quick heating type (also known as semi-storage type). Electric water heaters are smaller in size and larger in power, so they are indeed faster than storage-type electric water heaters in terms of heating speed, but they cannot achieve instant heat in spring and autumn, and they need to be preheated, that is, they need to wait. The dual-mode electric water heater can be used in the instant heating mode in spring, summer and autumn, and it can be heated immediately when it is turned on. [0003] However, after the existing electric water heater heats the cold w...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the prior art, after the electric water heater heats the cold water, when the hot water is not used in time, the heat will be slowly lost, and then the water heater will reheat the cooled hot water again. Due to the problem that the thermal energy resources in the country are not well utilized, a kind of heating equipment based on electric water heaters is proposed
