Water heater with hot water circulating system

Abstract

The invention discloses a water heater with a hot water circulating system. The inner structure of the whole box body is protected by a stainless steel box body; a cold water inlet tube is connected to an inlet water non-return valve; the inlet water non-return valve is connected to a municipal water supply cold water tube; a hot water outlet tube is connected to an electromagnetic water valve, ahot water circulating water outlet tube and the hot water circulating pump are connected, and are jointed at a joint, a jointed water tube is connected to a water flow inductor, the water flow inductor and a water consumption portion of a feeding terminal are connected through the hot water circulating water outlet tube, a terminal water consumption portion is connected to a return water non-return valve through a return water tube, and the return water non-return valve is connected to a return water tube, so that a hot water circulating pipeline is accomplished to realize hot water cycle. A hot water circulating system is provided with a circulating pump device inside the water heater; while the hot water circulating pump needs to automatically start, the water flow inductor controls start and stop of the hot water circulating pump; and the hot water circulating system is suitable for all water storage type water heaters. The hot water circulating system therein greatly improves waterconsumption efficiency, is more attractive, and saves space.

Description

technical field [0001] The present invention relates to a water heater, in particular to a water storage water heater without a hot water circulation system; Background technique [0002] Water storage water heaters are divided into many types, including air energy balcony wall-mounted type, solar balcony wall-mounted type, toilet wall-mounted type, horizontal type and vertical type, electric heating type, electric heating and air energy combination type, and electric heating and air energy combination type. Combined solar energy is suitable for all water storage water heaters. The advantage of storage water heaters is that they do not need to consider the weather conditions and set the temperature to heat automatically, and provide hot water for home and work at any time. However, the disadvantages of storage water heaters are obvious. When hot water is used, it needs to be released for a period of time to drain the cold water in the pipeline before hot water will flow out....

[0002] Water storage water heaters are divided into many types, including air energy balcony wall-mounted type, solar balcony wall-mounted type, toilet wall-mounted type, horizontal type and vertical type, electric heating type, electric heating and air energy combination type, and electric heating and air energy combination type. Combined solar energy is suitable for all water storage water heaters. The advantage of storage water heaters is that they do not need to consider the weather conditions and set the temperature to heat automatically, and provide hot water for home and work at any time. However, the disadvantages of storage water heaters are obvious. When hot water is used, it needs to be released for a period of time to drain the cold water in the pipeline before hot water will flow out. This is especially obvious when using it in winter, and it is a waste of water resources. Adding an external circulating pump is not only unsightly but also takes up a lot of external space
