Description

Technical Field

[0001] This invention relates to the field of heating system technology, specifically to a central heating system based on an air source heat pump system. Background Technology

[0002] For example, Chinese patent CN104315592A discloses an air source heat pump floor heating system, including an air source heat pump unit, a manifold, and an indoor bottom radiant heating system. The indoor bottom radiant heating system is buried under the indoor floor and includes a floor heating return pipe and a floor heating supply pipe. The floor heating return pipe and the floor heating supply pipe are arranged in a spiral shape and are spaced apart.

[0003] However, the above solutions have the following shortcomings: existing heating systems mostly use wall heating, floor heating, or radiators to heat rooms. However, wall heating and floor heating take a long time to heat up initially because their pipes are buried in the walls or floors. Radiators, on the other hand, are installed on the outer surface of the walls, which speeds up the heating process, but the surface temperature of radiators is high, and users may get burned if they accidentally touch them. Therefore, we have introduced a central heating system based on an air source heat pump system. Summary of the Invention

[0004] The purpose of this invention is to provide a central heating system based on an air source heat pump system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A central heating system based on an air source heat pump includes an air source heat pump body and a connecting box. A support pipe is fixedly connected inside the connecting box. Several sets of impellers are provided inside the support pipe. The impellers are fixedly sleeved on the outside of a connecting shaft. The connecting shaft is movably connected inside the support pipe. One end of the connecting shaft extends out of the support pipe and is fixedly connected to a fan. A heat-conducting pipe is provided at the end of the fan away from the support pipe. One end of the heat-conducting pipe is fixedly connected to the lower end of the support pipe, and the other end extends out of the connecting box and communicates with a heating pipe. The heating pipe is fixedly connected to the connecting box.

[0007] The heat pipe has several sets of connecting slots on the side away from the fan. The connecting slots are located inside the connecting box. Two sets of movable plates are movably connected inside the connecting box. Adsorption nets are provided on the side of the two sets of movable plates near the heat pipe. The two ends of the adsorption nets are fixedly connected to the two sets of movable plates respectively. Adsorption cotton strips are provided on the upper side of the movable plates. The adsorption cotton strips are fixedly connected to the connecting box. The lower end of the adsorption cotton strips extends into the movable plates and connects with the adsorption nets. The upper end of the adsorption cotton strips extends into the liquid storage chamber, which is located in the upper part of the connecting box.

[0008] Preferably, a connecting pipe is fixedly connected to one side of the air source heat pump body, and the end of the connecting pipe away from the air source heat pump body is fixedly connected to the connecting box and communicates with the support pipe.

[0009] Preferably, a connecting rod is fixedly connected to both the upper and lower ends of the movable plate. The connecting rod is movably connected to the connecting groove. A sliding rod is fixedly connected to one side of the lower connecting rod. The sliding rod is movably connected to the guide groove, which is opened in the connecting box. A spring is fixedly connected to the guide groove, and the other end of the spring is fixedly connected to the sliding rod.

[0010] Preferably, a sealing cap is snapped into the upper end of the liquid storage chamber, and a filter screen is fixedly connected to the upper end of the connecting box.

[0011] Preferably, the end of the heating pipe furthest from the connecting box is fixedly connected to the water tank, a water guide pipe is fixedly connected to the upper end of the water tank, and the end of the water guide pipe furthest from the water tank is fixedly connected to the air source heat pump body.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: When hot water passes through the support pipe, it drives the fan to rotate, allowing the surface temperature of the heat-conducting pipe to be carried into the external environment by the airflow, thus directly heating the external environment. Simultaneously, after passing through the heat-conducting pipe, the hot water enters the heating pipe, which can then heat the floor or walls, achieving rapid room heating. Furthermore, since the heat-conducting pipe is located inside the connecting box, users will not suffer burns. When the fan rotates, the movable plate opens, allowing the airflow to carry the fragrance liquid into the external environment, thus regulating the air while providing heating. After heating is complete, the movable door automatically closes to prevent external objects from entering the connecting box and affecting the normal operation of the fan.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-7 The present invention provides a technical solution:

[0023] Example 1:

[0024] A central heating system based on an air source heat pump system includes an air source heat pump body 1 and a connecting box 5. A support pipe 11 is fixedly connected inside the connecting box 5. The diameter of the support pipe 11 is smaller than that of the connecting pipe 4. When hot water enters the support pipe 11 from the connecting pipe 4, the water flow speed increases and drives the impeller 10 to start rotating. Several sets of impellers 10 are provided inside the support pipe 11. The impellers 10 are fixedly sleeved on the outside of the connecting shaft 22. The connecting shaft 22 is movably connected inside the support pipe 11. One end of the connecting shaft 22 extends out of the support pipe 11 and is fixedly connected to a fan 8. A heat conduction pipe 7 is provided at one end of the fan 8 away from the support pipe 11, and the other end extends out of the connecting box 5 and is connected to the heating pipe 9.

[0025] The heat pipe 7 is corrugated. One end of the heat pipe 7 is fixedly connected to the lower end of the support pipe 11. When hot water enters the heat pipe 7, it will heat it. At this time, the airflow blown out by the fan 8 will be heated after passing through the heat pipe 7. At the same time, when the airflow blown out by the fan 8 enters the connecting groove 12, the two sets of movable plates 13 located in the connecting groove 12 are blown open. The heating pipe 9 is fixedly connected to the connecting box 5.

[0026] Several sets of connecting slots 12 are provided on the side of the heat pipe 7 away from the fan 8. The connecting slots 12 are opened in the connecting box 5. Two sets of movable plates 13 are movably connected in the connecting box 5. The two sets of movable plates 13 are provided with an adsorption net 17 on the side of the heat pipe 7. The adsorption net 17 will absorb the fragrance liquid transferred by the adsorption cotton strip 18. The two ends of the adsorption net 17 are fixedly connected to the two sets of movable plates 13 respectively. When the airflow blown out by the fan 8 enters the connecting slot 12, the two sets of movable plates 13 will be opened when they are in the connecting slot 12.

[0027] When the two sets of movable plates 13 are opened, the adsorption net 17 will also be opened. The upper side of the movable plate 13 is provided with adsorption cotton strips 18, which are fixedly connected to the connecting box 5. The lower end of the adsorption cotton strips 18 extends into the movable plate 13 and is connected to the adsorption net 17. The upper end of the adsorption cotton strips 18 extends into the liquid storage chamber 14, which is located in the upper part of the connecting box 5. The liquid storage chamber 14 contains fragrance liquid. At this time, the adsorption cotton strips 18 draw the fragrance liquid into its interior and guide it into the adsorption net 17. At this time, the airflow blown out by the fan 8 will carry the fragrance liquid from the connecting groove 12 into the external environment when passing through the adsorption net 17.

[0028] Example 2:

[0029] Based on Embodiment 1, in order to allow the two sets of movable plates 13 located in the connecting groove 12 to close again after the fan 8 stops rotating, a connecting pipe 4 is fixedly connected to one side of the air source heat pump body 1. The end of the connecting pipe 4 away from the air source heat pump body 1 is fixedly connected to the connecting box 5 and connected to the support pipe 11. When the air source heat pump body 1 starts to work, the hot water generated by the air source heat pump body 1 is discharged into the connecting pipe 4. The hot water entering the connecting pipe 4 is guided into the support pipe 11. At this time, the impeller 10 rotates and drives the fan 8 to rotate synchronously. The upper and lower ends of the movable plate 13 are fixedly connected to the connecting rod 16.

[0030] The connecting rod 16 is movably connected to the connecting groove 12. A slide rod 19 is fixedly connected to one side of the lower connecting rod 16. The slide rod 19 is movably connected to the guide groove 20, which is opened in the connecting box 5. A spring 21 is fixedly connected to the guide groove 20. The other end of the spring 21 is fixedly connected to the slide rod 19. When the movable plate 13 is opened, it will drive the connecting rod 16 connected to its upper and lower ends to move. When the connecting rod 16 connected to its lower end moves, it will drive the slide rod 19 to move synchronously. The slide rod 19 moves along the guide groove 20 to compress the spring 21.

[0031] A sealing cap 15 is snapped into the upper end of the liquid storage chamber 14. When it is necessary to add fragrance liquid to the liquid storage chamber 14, simply unscrew the sealing cap 15 and pour the fragrance liquid into the liquid storage chamber 14. After pouring, tighten the sealing cap 15 again. A filter screen 6 is fixedly connected to the upper end of the connecting box 5. The filter screen 6 can filter the air entering the connecting box 5. The end of the heating pipe 9 away from the connecting box 5 is fixedly connected to the water tank 3. A water guide pipe 2 is fixedly connected to the upper end of the water tank 3. The end of the water guide pipe 2 away from the water tank 3 is fixedly connected to the air source heat pump body 1. After passing through the heat conduction pipe 7, the hot water enters the heating pipe 9. The heating pipe 9 will absorb the heat of the hot water again and heat the room in the walls or floor. The hot water passing through the heating pipe 9 finally enters the water tank 3 for storage and then enters the air source heat pump body 1 through the water guide pipe 2 for circulation.

[0032] Working principle: When the air source heat pump body 1 starts working, the hot water generated by the air source heat pump body 1 is discharged into the connecting pipe 4. The hot water entering the connecting pipe 4 is guided into the support pipe 11. Since the diameter of the connecting pipe 4 is larger than the diameter of the support pipe 11, the water flow speed entering the support pipe 11 is accelerated. The hot water moves along the support pipe 11, driving several sets of impellers 10 to start rotating. The rotation of the impellers 10 drives the fan 8 to start rotating. After passing through the support pipe 11, the hot water will enter the heat conduction pipe 7. The hot water will heat the heat conduction pipe 7 when it enters it. At this time, the airflow blown by the fan 8 will be heated when it passes through the heat conduction pipe 7. At the same time, when the airflow blown by the fan 8 enters the connecting groove 12, the two sets of movable plates 13 will be opened when they are in the connecting groove 12. When the movable plates 13 are opened, they drive the connecting rods 16 connected to their upper and lower ends to move.

[0033] When the connecting rod 16 at its lower end moves, it drives the slide rod 19 to move synchronously. The slide rod 19 moves along the guide groove 20 to compress the spring 21. When the two sets of movable plates 13 are opened, the adsorption net 17 will be opened. Since the liquid storage chamber 14 contains fragrance liquid, the adsorption cotton strip 18 will suck the fragrance liquid into its interior and guide it into the adsorption net 17. At this time, the airflow blown out by the fan 8 will carry the fragrance liquid from the connecting groove 12 into the external environment when it passes through the adsorption net 17.

[0034] After passing through the heat pipe 7, the hot water enters the heating pipe 9, where it absorbs heat from the water again and heats the room through the walls or floor. The hot water passing through the heating pipe 9 is then stored in the water tank 3 and circulated through the water pipe 2 into the air source heat pump body 1. When the air source heat pump body 1 stops working, the sliding rod 19 returns to its original position under the elastic force of the spring 21, and the two sets of movable plates 13 seal the connecting groove 12 again.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
