Description

Technical Field

[0001] The utility model relates to the technical field of heating and refrigeration equipment, in particular to a split air source heat pump water heater unit. Background Art

[0002] The split air source heat pump water heater is a new type of energy-saving and environmentally friendly equipment, mainly composed of an outdoor unit and an indoor unit. The outdoor unit mainly includes a compressor, a four-way valve, a gas-liquid separator and an evaporator, while the indoor unit mainly includes components such as a heat exchanger, a fan and a heat dissipation fin. This design makes the installation and maintenance of the equipment more convenient, and also improves the stability and reliability of the equipment. During operation, the heat in the air is pumped into the water heater through the heat pump to achieve the heating process. The heat pump compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant through the action of the compressor, and then condenses it into a liquid state after passing through the condenser. Finally, it is throttled and reduced in pressure and temperature by the expansion valve, and then enters the evaporator again to absorb heat. In this way, the heat transfer is completed in a cycle. The working principle of the heat pump The main advantage of the split air source heat pump water heater is its efficient energy utilization and environmental performance. Compared with traditional electric heating equipment, it can save a lot of electricity and will not produce any pollution.

[0003] When the outdoor unit of the existing split air source heat pump water heater unit dissipates heat, the heat exchanger is dissipated through the fins. The fan can take away the heat inside the heat exchanger to form a circulating airflow, thereby increasing the heat dissipation effect of the heat exchanger. However, the outdoor unit is installed outdoors without protection. In the spring in northern my country, there will be a lot of poplar cotton and willow catkins. The falling poplar cotton and willow catkins may adhere to the cooling fins, affecting the heat dissipation effect of the heat exchanger, resulting in a significant reduction in the heating and cooling effects of the air source heat pump water heater unit. In order to solve this technical problem, the utility model proposes a split air source heat pump water heater unit. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5As shown, a split air source heat pump water heater unit includes a frame 1, a blocking grid 2 and a scraper hook 3. A heat exchanger 4 is installed inside the frame 1. The frame 1 can carry and support the required components. Heat exchange is carried out through the heat exchanger 4, and heat energy is transferred from one fluid to another fluid to realize heat energy, improve combustion efficiency, reduce energy consumption and environmental pollution. A plurality of fans 5 are arranged inside the heat exchanger 4, and a plurality of heat dissipation fins 6 are symmetrically arranged outside the heat exchanger 4. The blocking grid 2 is located outside the heat exchanger 4, and the blocking grid 2 is installed on one side of the frame 1. The blocking grid 2 can block poplar cotton and catkins outside the outdoor unit to increase the stability of the heat exchanger 4 during operation. One side of the frame 1 is connected to two groups of bases 7, and each group of bases 7 has two, one of which is a base 7. A motor 8 is arranged on the outside, and the inner wall of each group of bases 7 is rotatably connected with a rotating shaft 9, one of which is connected to the output shaft of the motor 8. A group of sprockets 10 are installed on the outside of the rotating shaft 9, and the sprockets 10 are meshed with chains 11. A plurality of bases 2 12 arranged at equal distances are installed on the outside of the chain 11, and a support shaft 13 is movably connected to the inside of the base 2 12 at a fixed point. The outer surface of the support shaft 13 is connected to one side of a plurality of scraper hooks 3, and the plurality of scraper hooks 3 are in sliding contact with the inner wall of the blocking fence 2. The sprocket 10 is driven to rotate by the rotation of the motor 8, and the chain 11 is driven to rotate after the sprocket 10 rotates. The scraper hook 3 moves simultaneously with the chain 11, and the poplar cotton and catkins blocked on the blocking fence 2 are removed during the movement of the scraper hook 3, so that the blocking fence 2 has good air permeability.

[0023] A group of base three 16 is connected to one side of the frame 1, and a baffle 17 is connected to the inner side of the base three 16. The base three 16 can support the baffle 17 to increase the stability of the baffle 17. A plurality of scraping grooves 18 compatible with the scraping hook 3 are opened on the inner side of the baffle 17. After the scraping hook 3 removes the poplar cotton and willow catkins adhered to the blocking fence 2, it will adhere to the scraping hook 3. When the scraping hook 3 moves to the baffle 17 position, the hook enters the scraping groove 18. The scraping groove 18 can remove the poplar cotton and willow catkins on the scraping hook 3, making it convenient for the scraping hook 3 to scrape the poplar cotton and willow catkins on the blocking fence 2 again.

[0024] One end of the support shaft 13 outside the second base 12 is connected to a support plate 14, one side of the support plate 14 is connected to a tension spring 15, and the other end of the tension spring 15 is connected to one side of the second base 12, and is blocked when the scraper hook 3 contacts the scraper groove 18. The scraper hook 3 will tilt and swing backward, and the tension spring 15 can drive the scraper hook 3 to reset.

[0025] A plurality of heat dissipation fins 6 are installed on the outside of the heat exchanger 4 , and the plurality of heat dissipation fins 6 are arranged at equal distances. The heat dissipation fins 6 can increase the heat dissipation performance of the heat exchanger 4 and improve the heat dissipation performance of the heat exchanger 4 .

[0026] A plurality of fans 5 are installed inside the heat exchanger 4, and the plurality of fans 5 are arranged at equal distances. A plurality of protective covers 20 are installed on the upper surface of the heat exchanger 4, and the protective covers 20 are located above the fans 5. Debris dropped when the fans 5 rotate may damage the blades of the fans 5, and debris hit by the blades of the fans 5 may splash out and may also damage the heat exchanger 4. The protective cover 20 can prevent debris from entering the interior of the heat exchanger 4, thereby increasing the safety of the fans 5. The appearance of the protective cover 20 is similar to an L-shape, which can prevent rainwater from entering the interior of the outdoor unit on rainy days. A sound-absorbing damping plate 21 is connected to the outside of the protective cover 20, which can reduce the mechanical resonance amplitude of the outdoor unit during operation, reduce the sound waves generated by the mechanical vibration of the outdoor unit, and thus reduce the noise of the outdoor unit during operation.

[0027] A loading plate 19 is installed on the upper surface of the frame 1, and the motor 8 is connected to one side of the loading plate 19. The loading plate 19 can support the motor 8 to increase the stability of the motor 8. When the cotton wool and catkins float toward the outdoor unit, they are blocked outside by the blocking grid 2. When there are too many cotton wool and catkins stuck to the outside of the blocking grid 2, the motor 8 is started, and the motor 8 drives the rotating shaft 9 to rotate. At the same time, the rotating shaft 9 drives the sprocket 10 to rotate, and the sprocket 10 drives the chain 11 to rotate. At the same time, the scraper hook 3 moves with the chain 11. When the scraper hook 3 moves, the cotton wool and catkins on the blocking grid 2 are removed. When the scraper hook 3 moves to the scraping groove 18 position, the cotton wool and catkins on the scraper hook 3 are blocked by the scraping groove 18 and detached from the hook.
