Description

Technical Field

[0001] The present invention relates to the technical field of heat pump units, and particularly to an anti-corrosion dehumidifying heat pump unit for swimming pools. Background Technique

[0002] A swimming pool is a special place for people to carry out swimming activities. People can move or compete in it. Most swimming pools are built on the ground. According to the water temperature, they can be divided into general swimming pools and warm water swimming pools, which are divided into indoor and outdoor types. When an indoor pool is in use, the water is usually insulated. At this time, the water naturally evaporates into the air, resulting in an increase in indoor air humidity. In order to reduce humidity and improve comfort, it is usually necessary to dehumidify through a dehumidifying heat pump unit.

[0003] When a traditional dehumidifying heat pump unit is in use, the dehumidifying heat pump unit is usually directly placed in a suitable position, and then the dehumidifying heat pump unit is directly started to condense the water vapor in the air. At this time, the condensed water flows randomly, which is not convenient for centralized collection and discharge. For this reason, we propose an anti-corrosion dehumidifying heat pump unit for swimming pools to solve the above problems. Summary of the Invention

The compressor 3 is fixedly connected to the expansion valve 5 through a connecting pipe 7. A filtering device 9 is arranged below the evaporator 8. The compressor 3 can directly drive the coolant to circulate in the condenser 4, the expansion valve 5, the connecting pipe 7 and the evaporator 8 to achieve refrigeration. At this time, the exhaust fan inside the outer shell 1 drives air into the evaporator 8, and the evaporator 8 condenses the water vapor in the pool air to reduce the humidity in the pool air. During use, the heat conduction pipeline 87 composed of titanium alloy blocks can reduce the corrosion caused by additives in the pool.

[0017] As a further embodiment of the above invention: The evaporator 8 includes heat-conducting fins 81, a connecting plate 82, a shielding body 86, and a heat-conducting pipe 87. A fixing groove 85 is formed in the heat-conducting fin 81. The heat-conducting fin 81 is fixedly connected to the connecting plate 82 through the formed fixing groove 85. The heat-conducting fins 81 are evenly distributed up and down on the outside of the connecting plate 82, and the connecting plates 82 are evenly distributed in the heat-conducting fins 81.

The bottom of the first rubber block 863 and the top of the second rubber block 864 are in close contact with the heat-conducting fin 81. Through this setting, the wavy heat-conducting fin 81 can condense and concentrate the water vapor in the air. Then, the condensed water droplets are guided into the collection box 91 through the flow guide grooves 84 formed in the connecting plate 82 for collection. At the same time, the V-shaped plate 862 and the baffle 861 are installed on both the front and rear sides of the heat-conducting fin 81 through the first rubber block 863 and the second rubber block 864, preventing the condensed water droplets from flowing out from both the front and rear sides of the heat-conducting fin 81 and ensuring that the water droplets can accurately flow into the collection box 91.

Through holes 962 are arranged in the top plate 961 in a uniformly distributed manner. An external thread pipe 964 is fixedly connected to the position of the through hole 962 opened at the bottom of the top plate 961. An internal thread pipe 965 is threadedly connected to the outside of the external thread pipe 964. The bottom of the internal thread pipe 965 is fixedly connected to a fixing shell 966. A water outlet hole is opened at the bottom of the fixing shell 966. A filtering main body 967 is arranged inside the fixing shell 966.

The bottom of the sealing frame 963 is in close contact with the support frame 95 and the fixing rod 97 respectively. Through this setting, the condensed water can be collected by the collection box 91. During the collection process, water droplets enter the external thread pipe 964 through the through holes 962 opened in the top plate 961. After that, the water droplets flow into the bottom of the collection box 91 after being filtered by the filtering main body 967, and finally are discharged through the drain valve 10. After long-term use, the first bolt 94 and the second bolt 98 are removed. Then, the fixing plate 92 and the top plate 961 can be removed from the collection box 91. The fixing shell 966 is rotated. After the fixing shell 966 is removed, the filtering main body 967 can be maintained and replaced. Finally, the fixing plate 92 and the top plate 961 are reinstalled into the collection box 91 and sealed by the sealing plate 93 and the sealing frame 963 to prevent water leakage.

[0019] During specific implementation: When this pool dehumidification heat pump unit is in use, first place the pool dehumidification heat pump unit in a suitable position, and then connect the power supply. At this time, start the expansion valve 5 and the compressor 3 through the external controller. The compressor 3 drives the refrigerant to circulate in the compressor 3, the condenser 4, and the evaporator 8 through the connecting pipe 7 and the heat conduction pipe. At this time, the air blower in the housing 1 drives the air to flow, and the air in the swimming pool hall flows into the evaporator 8. At this time, the water vapor in the air encounters the cooled heat conduction fins 81. At this time, the water vapor releases heat when cooled and liquefies into small water droplets attached to the heat conduction fins 81. As the small water droplets increase, the small water droplets merge with each other to form large water droplets. At this time, the large water droplets flow downward under the action of gravity through the wavy design of the heat conduction fins 81. At the same time, some large water droplets enter the inclined groove 83 opened by the heat conduction fins 81 and are guided. Finally, the large water droplets contact the connecting plate 82. As the large water droplets gather, the large water droplets flow downward through the diversion groove 84 provided by the connecting plate 82 and finally drip onto the surface of the top plate 961 in the collection box 91. At the same time, when the water droplets gather at the position of the connecting plate 82, the baffle 861 fixed to the side of the heat conduction fins 81 by the first rubber block 863 and the second rubber block 864 can prevent the water from flowing out from the side, ensuring that the water can accurately enter the collection box 91 through the diversion groove 84 opened by the connecting plate 82. As the water on the surface of the top plate 961 gradually increases, the water flows downward through the through hole 962 opened by the top plate 961 into the external thread pipe 964, and then flows downward through the external thread pipe 964 into the filter body 967. After passing through the filter body 967, the water flows through the water outlet hole opened at the bottom of the fixed shell 966 and into the collection box 91. As the water in the collection box 91 increases, open the drain valve 10 to drain the water. After long-term use, directly remove the first bolt 94 and the second bolt 98, and then remove the fixing plate 92 forward. After that, the top plate 961 can be removed forward from the collection box 91. At this time, rotate the fixed shell 966, and the fixed shell 966 drives the internal thread pipe 965 to rotate outside the external thread pipe 964, and remove the external thread pipe 964 from the outside of the internal thread pipe 965. Then remove the sealing ring 968 and the filter body 967 from the fixed shell 966, maintain or replace the filter body 967. After that, put the filter body 967 and the sealing ring 968 into the fixed shell 966, and thread the internal thread pipe 965 onto the outside of the external thread pipe 964 until the sealing ring 968 is in close contact with the external thread pipe 964 and the sealing body respectively, preventing the water from flowing out without being sealed by the sealing body, ensuring the filtration of the water and preventing the drain valve 10 from being blocked.
