Due to the limited volume in high-level water tank, when a large amount of heating demand is realized in the prior art, external water tank circulation heating form is often used. But the form of the external water tank, because the volume of external water tank is too large, the water in the whole external water tank is heated synchronously in the circulation process, so it needs a long time to provide the hot water that meets the demand, and therefore it is urgent to solve.

Because the water flow channel increases the water flow distance, the water in the first end and the second end of water flow channel will not mix quickly, therefore, the water in the first end of water flow channel is still in the state of relatively low temperature, thereby realizing that the water in water flow channel forms temperature gradually increasing partition between the first end and the second end.

DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] For the convenience of understanding, the specific structure and working mode of the utility model are further described as follows in combination with the drawings:

[0021] The specific structure of the utility model refers to Figures 1-2 The main structure includes solar hot water assembly 20 and heat preservation water tank 10, wherein the inner cavity of heat preservation water tank 10 is provided with water flow channel 12 that can increase the flowing distance of water in heat preservation water tank 10. In addition, the water inlet end of solar hot water assembly 20 is communicated with the first end of water flow channel 12 through first water delivery pipe 22, and first water delivery pipe 22 is provided with first water pump 23, and the water outlet end of solar hot water assembly 20 is communicated with the second end of water flow channel 12 through first return water pipe 21. The second end of water flow channel 12 is also communicated with user water delivery pipe 40 for supplying water to users, and the first end of water flow channel 12 is communicated with water replenishing pipe 51.

[0022] The application adopts the intermittent water circulation heating mode in the heat preservation water tank 10. When in use, the solar water heating assembly 20 is used to heat the water in its own tank. After the water temperature in the tank is heated to a certain temperature, the first water pump 23 is started to make the water at the first end of the water flow channel 12 enter the solar water heating assembly 20 for re-heating. At the same time, the water heated by the solar water heating assembly 20 is circulated to the second end of the water flow channel 12. Because the water flow channel 12 increases the flow distance of the water, the water at the first end and the second end of the water flow channel 12 will not be quickly mixed, so the water at the first end of the water flow channel 12 is still in a relatively low temperature state, thereby forming a temperature gradually increasing partition between the first end and the second end of the water flow channel 12. Because the water supply pipe 40 for the user is connected to the second end of the water flow channel 12, the heated water can be used after the solar water heating assembly 20 supplies water to the second end of the water flow channel 12 for the first time, without waiting for the solar water heating assembly 20 to uniformly heat all the water in the heat preservation water tank 10, thereby reducing the waiting time for the heat preservation water tank 10 to produce hot water that meets the demand. In addition, the water supplied from the heat preservation water tank 10 into the solar water heating assembly 20 each time is the water with the lowest temperature in the heat preservation water tank 10, which has a larger temperature difference with the solar water heating assembly 20, so that better heat exchange effect can be achieved, and the heating effect of the water in the heat preservation water tank 10 is improved.

[0023] It is worth mentioning that in the present application, the first water pump 23 is installed on the first water supply pipe 22 instead of the first water return pipe 21, which makes the water in the heat preservation water tank 10 circulate outward in a suction manner. Compared with the extrusion outward circulation mode in which the first water pump 23 is installed on the first water return pipe 21, the water in the heat preservation water tank 10 has a small mixing force, which is beneficial to maintaining the temperature difference between the water at the first end and the second end of the water flow channel 12.

[0024] In addition, the volume of the tank of the solar water heating assembly 20 does not need to be set too large in order to achieve the rapid rise of the water temperature in the tank of the solar water heating assembly 20.

[0025] Specifically, as shown in FIG. 1, the heat preservation water tank 10 is connected to the solar water heating assembly 20 through the first water supply pipe 22 and the first water return pipe 21. The first water supply pipe 22 is connected to the first end of the water flow channel 12, and the first water return pipe 21 is connected to the second end of the water flow channel 12. The first water pump 23 is installed on the first water supply pipe 22. Figure 2As shown, the inner cavity of the heat preservation water tank 10 is divided into at least three vertically arranged flow channel cavities by the partition plate 11, the top and bottom of the middle flow channel cavity are respectively communicated with adjacent flow channel cavities, and all the flow channel cavities together form the water flow channel 12; the water supplement pipe 51 is communicated with the high-position water supplement tank 50. The water flow channel 12 is formed in this way, and due to the vertical arrangement of the flow channel cavities, the water in the water flow channel 12 will not flow upward under the action of the water pumping force of the first water pump 23, which reduces the water mixing degree between adjacent flow channel cavities and is more conducive to maintaining the temperature difference of the water at the first end and the second end of the water flow channel 12, thereby realizing temperature zoning of the water in the water flow channel 12. In addition, the high-position water supplement tank 50 is arranged, when the water in the heat preservation water tank 10 is lost, new water is automatically supplemented into the first end of the low-temperature zone of the water flow channel 12, which will not cool the water in the second end of the high-temperature zone of the water flow channel 12, and can also ensure that the heat preservation water tank 10 is always in a full water state, thereby realizing stable circulation of the water between the heat preservation water tank 10 and the solar water heating assembly 20. Of course, in actual implementation, the high-position water supplement tank 50 can also be replaced by a normally open pressurized water pipe.

[0026] Further, the partition plate 11 is made of heat insulation material, which can reduce the heat conduction between the water in adjacent flow channel cavities and is conducive to maintaining the temperature difference of the water at the first end and the second end of the water flow channel 12.

[0027] Of course, in actual implementation, the water flow channel 12 can adopt a spiral structure such as a mosquito coil disc, and the spiral structure of the water flow channel 12 is horizontally arranged, which can also achieve the effect of maintaining the temperature difference of the water at both ends of the water flow channel 12, and does not need to arrange the high-position water supplement tank 50 to continuously supplement water into the water flow channel 12. Of course, this arrangement structure will make the mixing degree of the water in the water flow channel 12 larger, so the temperature difference between the two ends of the water flow channel 12 will be smaller.

[0028] On the basis of the above, Figure 1 and Figure 2 As shown, the air energy water heating assembly 30 is further included, the water inlet end of the air energy water heating assembly 30 is communicated with the first end of the water flow channel 12 through the second water supply pipe 32, and the second water pump 33 is installed on the second water supply pipe 32, and the water outlet end of the air energy water heating assembly 30 is communicated with the second end of the water flow channel 12 through the second water return pipe 31. Since the solar water heating assembly 20 is greatly affected by the weather and is difficult to realize stable heating capacity. In this application, the air energy water heating assembly 30 is also added to the heating operation of the water in the heat preservation water tank 10. The pipeline arrangement structure of the air energy water heating assembly 30 in this application realizes the zoning of the water in the water flow channel 12 between the first end and the second end, and the temperature gradually increases. Specifically, the air energy water heating assembly 30 can adopt the air source heat pump in the prior art.

[0029] It is worth mentioning that in the embodiment provided with the air energy water heating assembly 30, the solar water heating assembly 20 is still preferred to work in actual implementation of the present application, and the air energy water heating assembly 30 is used to assist heating when the solar water heating assembly 20 is insufficient to heat due to the rainy and snowy weather. In addition, when the low-valley electricity is abundant at night, the air energy water heating assembly 30 can be used to heat and store in the heat preservation water tank 10, so as to realize partial heat storage of the low-valley electricity, and the stored heat source can be used as a heat source for heating together with the solar water heating assembly 20 during the daytime,

[0030] In addition, as shown in Figure 1 The valve is installed on the first water supply pipe 22, the second water supply pipe 32, the first water return pipe 21 and the second water return pipe 31, and the air energy water heating assembly 30 or the solar water heating assembly 20 can work alone by simultaneously closing the valves on the first water supply pipe 22 and the first water return pipe 21 or simultaneously closing the valves on the second water supply pipe 32 and the second water return pipe 31.

[0031] On the basis, the user water pump 41 is installed on the user water supply pipe 40, the middle part of the water flow channel 12 is communicated with the heating water return pipe 60, and the valve is installed on the heating water return pipe 60, so that the water in the heat preservation water tank 10 can be used not only for living but also for heating. By opening the user water pump 41, the heated water enters the user heating equipment through the user water supply pipe 40, and returns to the heat preservation water tank 10 through the heating water return pipe 60 after heating heat exchange. Since the water after heating circulation still has a certain temperature, the middle part of the heating water return pipe 60 is connected with the water flow channel 12, so as to prevent the water at the first end of the water flow channel 12 from being heated and the water at the second end of the water flow channel 12 from being cooled.

[0032] Of course, for those skilled in the art, the present application is not limited to the details of the above exemplary embodiments, but also includes the same or similar structures that can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0033] In addition, it should be understood that although the present application is described in the form of embodiments, each embodiment does not contain only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be properly combined to form other embodiments that can be understood by those skilled in the art.
