Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically a heating device based on solar energy and an air source heat pump. Background Technology

[0002] Solar heating refers to a system that converts dispersed solar energy into readily usable hot water using collectors (such as flat-plate solar collectors), and then delivers the hot water to heating terminals (such as underfloor heating systems and radiator systems) to provide room heating. Air source heat pump heating is an energy-saving device that utilizes high-grade energy to move heat from a low-grade heat source (air) to a high-grade heat source. This heat is used to heat water, which is then delivered to heating terminals to provide warmth.

[0003] Solar heating and air source heat pump heating each have their own advantages and disadvantages, and their advantages and disadvantages can often complement each other. Solar energy does not require electricity and is very economical, but it cannot work without sunlight. Air source heat pumps use electricity and are not as energy-efficient as solar energy, but their use is not restricted. When there is no sun, air source heat pumps can be used to supplement heating.

[0004] The best results are achieved by combining solar heating and air-source heat pump heating. However, the installation of both systems is currently extremely inconvenient, requiring a large area and resulting in a very messy layout. Furthermore, current heating systems are not easy to adjust the hot water temperature, leading to unsatisfactory room heating.

[0005] Therefore, there is a need to provide a heating device based on solar energy and air source heat pumps. Utility Model Content

[0006] The purpose of this invention is to provide a heating device based on solar energy and an air source heat pump to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A heating device based on solar energy and an air source heat pump includes a base plate that can be installed on the roof of a household requiring heating. The base plate includes a front end for installing the air source heat pump and a rear end for installing an insulated water tank. It also includes a transition section connecting the front and rear ends for installing quick-connect components. Support frames are provided at the two side edges of the front end, and the top of the support frames is used to install solar energy components.

[0009] Preferably, the support frame includes vertical frames located at the two edges of the front end, and a slanted frame located at the top of the vertical frames, on which solar panels are mounted.

[0010] Preferably, the interior of the insulated water tank is divided into several cavities, and adjacent cavities are separated by insulation material.

[0011] Preferably, the plurality of cavities includes a first cavity, a second cavity, and a third cavity, which are separated from each other by insulation panels.

[0012] Preferably, the quick-connect assembly has an internal communication system consisting of valves and connecting water pipes. This communication system extends to the outside of the quick-connect assembly to form corresponding interfaces, which are used to connect to several cavities of the insulated water tank, the solar panel, and the air source heat pump. This communication system controls the on / off relationship between the several cavities of the insulated water tank and the solar panel and air source heat pump.

[0013] Preferably, the quick-connect assembly is provided with a water mixing device, which includes a mounting base installed in the quick-connect assembly and a water mixing tank installed on the mounting base. The water mixing tank is provided with a stirring rod assembly that is driven and connected to a stirring motor.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5As shown, this utility model includes a base plate 1, with through holes at the corners of the base plate. The base plate 1 is fixed to the roof surface through the through holes and common fasteners such as bolts.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, the base plate 1 includes a front end portion 11 located at the front and a rear end portion 12 located at the rear, as well as a transition portion 13 connecting the front end portion 11 and the rear end portion 12; an air source heat pump 4 is installed on the front end portion 11, an insulated water tank 5 is installed on the rear end portion 12, and a quick-connect assembly 6 is installed on the transition portion 13. Furthermore, support frames 2 are provided at the two side edges of the front end portion 11, and the support frames 2 are used to install solar panels 3, specifically, as shown... Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, the support frame 2 includes vertical frames 21 located at the two edges of the front end 11 and inclined frames 22 connected to and installed at the upper end of the front end 11. Solar panels 3 are installed on the inclined frames 22. In this embodiment, the height of the inclined frames 22 is higher than that of the installed air source heat pump 4, so that the solar panels 3 and the air source heat pump 4 are installed at different heights on the same roof surface. Therefore, this utility model can save installation space. At the same time, the structure of the inclined frames 22 allows the solar panels 3 to be installed at a higher position, much higher than the height of direct installation on the roof surface in the traditional method, making it easier for the solar panels 3 to receive sunlight.

[0030] In this embodiment, the air source heat pump 4, the insulated water tank 5 and the solar panel 3 are systematically connected by the quick-connect component 6, so that the insulated water tank 5 can rhythmically perform a whole set of heating operations such as heating the water tank and supplying water to the residents below the roof.

[0031] like Figure 3As shown, the insulated water tank 5 of this utility model has a first cavity 51, a second cavity 52, and a third cavity 53 formed in sequence. The first cavity 51, the second cavity 52, and the third cavity 53 are not connected to each other. Specifically, the first cavity 51, the second cavity 52, and the third cavity 53 are separated by an insulation layer, dividing the insulated water tank 5 into the first cavity 51, the second cavity 52, and the third cavity 53 so that they can store water separately and be heated separately. The first cavity 51, the second cavity 52, and the third cavity 53 are systematically connected by quick-connect components 6, so that the first cavity 51, the second cavity 52, and the third cavity 53 can be connected in sequence. The second chamber 52 and the third chamber 53 can be controlled to heat water circulation through the air source heat pump 4 or the solar panel 3, respectively. The specific heating process is as follows: for example, by controlling the connection between the first chamber 51 and the air source heat pump 4, the heat generated by the compression operation of the air source heat pump 4 heats the water circulating in the first chamber 51. This cycle makes the water temperature in the first chamber 51 rise higher and higher until the required temperature is reached. The heating control process of the second chamber 52 and the third chamber 53 or the solar panel 3 is similar to the above. Dividing them into different chambers allows the first chamber 51, the second chamber 52 and the third chamber 53 to be heated at different temperatures, which can provide more flexible heating.

[0032] Furthermore, such as Figure 2 , Figure 3 , Figure 4 as well as Figure 6 As shown, the quick-connect assembly 6 of this utility model is provided with a valve 7 and a connecting water pipe 8. The connecting water pipe 8 is correspondingly connected to the interfaces provided on the outer surface of the quick-connect assembly 6. These interfaces are connected to the first cavity 51, the second cavity 52, and the third cavity 53, as well as the air source heat pump 4 and the solar panel 3. Inside the quick-connect assembly 6: the connecting water pipe 8 connecting to the external interfaces is systematically connected to form a communication system through the valve 7 and the power pump. The valve 7 and the power pump are connected to a unified controller, and the system control is realized through the controller; as Figure 2 and Figure 4 As shown, the opening and closing of valve 7 controls the connection between the first chamber 51, the second chamber 52, and the third chamber 53 and the air source heat pump 4 and the solar panel 3. For example, to connect the third chamber 53 and the solar panel 3, valve 7 connected to the third chamber 53 and the solar panel 3 can be opened, while valve 7 connected to the first chamber 51, the second chamber 52, and the air source heat pump 4 can be closed. At this time, under the action of the power pump, only the first chamber 51 and the solar panel 3 will have water circulation.

[0033] Furthermore, as an optimization of this embodiment, a mixing device 9 is also provided inside the quick-connect assembly 6. This mixing device 9 is used to mix water from the first cavity 51, the second cavity 52, and the third cavity 53 at different temperatures to obtain warm water at the required temperature. Specifically, the mixing device 9 includes a mounting base 92 fixed to the bottom surface of the quick-connect assembly 6, a mixing tank 91 mounted on the mounting base 92, and a stirring rod assembly 93 installed in the mixing tank 91. The mixing tank 91 is connected to a hot water supply quick-connect pipe 101 located on the outer side of the quick-connect assembly 6. A cold water supply quick-connect pipe 102 is also formed on the outer side of the quick-connect assembly 6. The cold water supply quick-connect pipe 102 is connected to the connecting water pipe 8 that flows back to the first cavity 51, the second cavity 52, and the third cavity 53 inside the quick-connect assembly 6. The hot water supply quick-connect pipe 101 and the cold water supply quick-connect pipe 102 are connected to the household to form circulating water for heating. More specifically, the stirring rod assembly 93 includes a rotating rod 931 rotatably mounted in the mixing tank 91 and stirring blades 932 disposed on the surface of the rotating rod 931. The stirring blades 932 are spiral blades arranged around the rotating rod 931. The rotating rod 931 is connected to a stirring motor 94. Starting the stirring motor 94 can quickly stir water at different temperatures and accelerate temperature adjustment.

[0034] In use, this utility model firstly controls the selection of either the air source heat pump 4 or the solar panel 3 to heat the water in the first cavity 51, the second cavity 52, or the third cavity 53 according to environmental conditions. For example, when it is cloudy and the solar panel 3 is not heating well, the air source heat pump 4 can be switched to heat the water. Moreover, the temperatures of the first cavity 51, the second cavity 52, and the third cavity 53 are different. For example, the water in the first cavity 51 is heated to the highest temperature, the second cavity 52 to the second highest temperature, and the third cavity 53 to the lowest temperature. Then, when heating is required, the water temperature is first adjusted by the mixing device 9, and finally, the water is connected to the household through the hot water supply quick-connect pipe 101 and the cold water supply quick-connect pipe 102 to achieve circulating heating.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
