Embodiment 1

[0031] Such as figure 1 As shown, a central hot water circulation system includes: a gas water heater 1, a water storage tank 2, a water pipeline 3 and a cold water inlet pipe 4, the water storage tank 2 is only supplied with water by the gas water heater 1, and the water pipeline 3 The hot water is supplied by the water storage tank 2, and the water point 5 is provided on the water pipeline 3, and the cold water inlet pipe 4 provides cold water for the gas water heater 1 and the water point 5; it is characterized in that the gas water heater outlet 15 -Water storage tank-2 Gas water heater water inlet 16 constitutes a first circulation loop, said gas water heater outlet 15-water storage tank 2-water pipeline 3-gas water heater water inlet 16 constitutes a second circulation loop.

[0032] Wherein, a circulation pump 6 is provided on the water inlet end of the gas water heater 1 , and the circulation pump 6 is shared by the first circulation loop and the second circulation loo...

Embodiment 2

[0038] Such as figure 2 As shown, the structure of the central hot water circulation system provided by this embodiment is basically the same as that of Embodiment 1, the difference is that there are three water pipelines 3, and each water pipeline 3 is connected in parallel between the water storage tank 2 and the Between the circulating pumps 6, a cut-off valve is arranged on each water pipeline 3. In actual application, different water pipelines 3 are provided with water points in different rooms or on different floors.

[0039] Today's large-scale and villa-type users have more rooms and bathrooms, and the demand for instant heating is not necessarily the whole house. In this embodiment, layered control is realized by setting multiple water pipelines, that is, personalized control of each room of a large apartment can be realized, and instant heating can be realized according to people's needs, thereby achieving comfort and energy saving.

Embodiment 3

[0041] Such as image 3 As shown, the central hot water circulation system provided by this embodiment is basically the same in structure as the first embodiment, the difference is that a drying rack 11 is connected to the water pipeline 3, and the drying rack 11 is located at the water point 5 downstream. Here, upstream and downstream are defined by the water flow direction of the second circulation loop.

[0042] Because the water storage tank 2 stores a large amount of high-temperature domestic hot water, and the water temperature in the water storage tank 2 is much higher than the normal use hot water temperature. The central hot water circulation system provided in this embodiment can easily dry clothes by using high-temperature water by adding a drying rack 11 .

Abstract

The invention discloses a central hot water circulating system which comprises a gas water heater, a water storage tank, a water-using pipeline and a cold water inlet pipe. Water of the water storage tank is only supplied by the gas water heater, and the water of the water-using pipeline is supplied by the water storage tank; water-using points are arranged on the water-using pipeline, and the cold water inlet pipe supplies cold water to the gas water heater and the water-using points; and the central hot water circulating system is characterized in that a first circulating loop is form by the water outlet end of the gas water heater, the water storage tank, the water inlet end of the gas water heater, and the a second circulating loop is form by the water outlet end of the gas water heater, the water storage tank, the water-using pipeline and the water inlet end of the gas water heater. According to the central hot water circulating system, the two circulating loops are arranged, so that a large amount of hot water is kept in the water storage tank all the time, the effect that the hot water is simultaneously used by a plurality of hot water points can be achieved, and the effect that the water is instantly heated the moment all the external water-using points are opened can also be achieved.

Description

technical field [0001] The invention relates to the technical field of central hot water, in particular to a central hot water circulation system. Background technique [0002] Gas water heaters are one of the necessary devices in people's daily life. There are many types. Water heaters can provide people with safe and comfortable hot water all the time. After all, the instant gas water heater has a limited water output. When there are multiple water points that demand a large amount of hot water at the same time, there will be insufficient water and low water temperature. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a central hot water circulation system with simple structure, which can not only ensure the simultaneous use of hot water at multiple water points, but also provide instant heating. [0004] To achieve the above object, the present invention adopts the following technica...
