Description

Technical Field

[0001] This utility model belongs to the technical field of air source heat pump water heaters, specifically relating to an air source heat pump water heater with low water level laminar flow water injection technology. Background Technology

[0002] Air source heat pump water heaters are widely used due to their high efficiency and energy saving. In existing technologies, to improve the thermal stratification effect in the water tank and the water intake experience, some products have introduced low-water-level laminar flow water injection technology. This technology aims to reduce disturbance to the internal water temperature layer by injecting water smoothly and slowly when the water level is low.

[0003] During hot water output, water pressure and water flow stability are key performance indicators. Currently, most water heaters use a fixed inner diameter design for their outlet pipes, the core problem of which is that the inner diameter of the outlet pipe cannot be adjusted. At high water levels, the static pressure is high, resulting in ideal water pressure; however, as the water level drops, the driving pressure becomes insufficient, leading to a decrease in water flow and a significant drop in water pressure within the fixed pipe diameter, and even intermittent water flow, seriously affecting user comfort. Utility Model Content

[0004] To address the problem that the inner diameter of the water outlet pipe cannot be adjusted in existing technologies, this utility model provides an air source heat pump water heater with low-water-level laminar flow water injection technology. Its purpose is to adjust the inner diameter of the water inlet of the water outlet pipe by adding a mechanical structure to the water outlet pipe.

[0005] The technical solution adopted in this utility model is as follows: An air-source heat pump water heater with low-water-level laminar flow water injection technology, characterized in that it comprises: The host computer is hollow inside.

[0007] Preferably, the fixed ring has an annular groove inside, a first sliding groove inside, and a second sliding groove on the outer surface of the fixed ring.

The sliding post is also provided in the second sliding groove, which is slidably connected to the second sliding groove. The sliding post guides the arc block to slide along the trajectory of the second sliding groove.

[0008] Preferably, the rotating member includes: A rotating ring is disposed on the outer surface of the fixed ring, and the rotating ring is rotatably connected to the fixed ring; A telescopic component is provided inside the rotating ring. One end of the telescopic component is fixedly connected to the rotating ring, and the other end of the telescopic component passes through the second sliding groove and is fixedly connected to the arc block.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1.

A buoyancy plate 8 is provided on inner diameter adjustment module 6, which is fixedly connected to buoyancy plate 8.

The inner diameter adjustment module 6 includes: A fixing ring 61 is fixedly connected at one end to the water outlet pipe 5 and at the other end to the buoyancy plate 8. Rotary shrink mechanism 7 is mounted on fixed ring 61 and is rotatably connected to fixed ring 61.

[0018] Preferably, the buoyancy plate 8 is disc-shaped, and the bottom of the buoyancy plate 8 is provided with a horn cover 11, which is connected to the water outlet 10. The inside of the horn cover 11 is provided with a filter screen 12, which is fixedly connected to the horn cover 11.

[0019] Preferably, the fixed ring 61 has an annular groove 62 inside, a first sliding groove 63 inside, and a second sliding groove 64 on the outer surface of the fixed ring 61. The first sliding groove 63 is opened in the annular groove 62, and the second sliding groove 64 communicates with the annular groove 62. The rotating retraction mechanism 7 includes: Arc block 71 is disposed in an annular groove 62 and is slidably connected to an annular groove 62; Rotating component 73 is mounted on fixed ring 61 and passes through second sliding groove 64 to be fixedly connected to arc block 71. The arc block 71 is provided with a sliding post 72, which is fixedly connected to the arc block 71. The sliding post 72 is also provided in the second sliding groove 64, and the sliding post 72 is slidably connected to the second sliding groove 64. The sliding post 72 guides the arc block 71 to slide along the trajectory of the second sliding groove 64.

[0020] Preferably, the rotating member 73 includes: A rotating ring 74 is disposed on the outer surface of a fixed ring 61, and the rotating ring 74 is rotatably connected to the fixed ring 61. The telescopic component 75 is located inside the rotating ring 74. One end of the telescopic component 75 is fixedly connected to the rotating ring 74, and the other end of the telescopic component 75 passes through the second sliding groove 64 and is fixedly connected to the arc block 71.

[0021] Preferably, the telescopic component 75 includes: a sleeve rod 76, a spring 77, and a sleeve 78; the sleeve rod 76 is fixedly connected to the rotating ring 74, the sleeve 78 is sleeved on the sleeve rod 76, the sleeve 78 is slidably connected to the sleeve rod 76, the sleeve rod 76 passes through the second sliding groove 64 and is fixedly connected to the arc block 71, the sleeve rod 76 is also slidably connected to the second sliding groove 64, the spring 77 is located between the sleeve rod 76 and the sleeve 78, and the spring 77 is fixedly connected to both the sleeve rod 76 and the sleeve 78.

[0023] Preferably, a sealing ring 9 is provided between the rotating ring 74 and the fixed ring 61.

[0024] The specific operating procedure of this utility model is based on the following working principle: First, the system employs a low-level laminar flow water injection technology. Since hot water is less dense than cold water, this technology injects cold water from the bottom of the storage tank 2 and extracts hot water from the top. This inlet and outlet method effectively avoids turbulence caused by the mixing of hot and cold water, thereby reducing heat loss and lowering reheating energy consumption. The buoyancy plate 8 at the top floats with the water level, ensuring that the inlet of the outlet pipe 5 is always located at the top of the tank to extract the hottest water.

[0025] When the inner diameter of the water outlet pipe 5 needs to be adjusted, it is achieved by manually rotating the rotating ring 74. Rotating the rotating ring 74 clockwise causes the internal telescopic component 75 and the arc block 71 to rotate synchronously. The arc block 71 slides from the outside to the inside along the trajectory of the first sliding groove 63 on the fixed ring 61, while the spring 77 inside the telescopic component 75 extends. When the sliding column 72 reaches the end of the sliding groove, the multiple arc blocks 71 converge and fit together, forming a complete ring, thereby reducing the effective inner diameter of the water outlet pipe 5. Conversely, rotating the rotating ring 74 counterclockwise causes the arc blocks 71 to slide outward along the trajectory, thus increasing the pipe diameter.

[0026] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
