[0002] The evaporation of water on the surface of an indoor constant temperature swimming pool will increase the indoor air humidity, affect human comfort, and cause indoor water vapor erosion. Therefore, the swimming pool needs to be dehumidified. The current variable frequency swimming pool constant temperature dehumidification heat pump unit can effectively control the humidity in the swimming pool room.
[0003] When dehumidifying, the existing variable frequency swimming pool constant temperature dehumidification heat pump unit needs to suck the new air and the old air into the duct through the return air duct for air exchange to achieve constant temperature dehumidification of the swimming pool. However, when the return air duct is exchanging air, the old air and the new air inhaled into the duct are easily condensed and mixed into water droplets after being sucked into the return air duct. The water droplets are easy to adhere to the inner wall of the return air duct, and the impurities contained in the water droplets are easy to cause dirt accumulation in the duct when the water droplets dry up. When the dirt accumulates on the wall of the return air duct, the return air effect of the return air duct will deteriorate and the difficulty of subsequent air circulation and purification will be increased.
[0004] Therefore, it is necessary to design a variable frequency swimming pool constant temperature dehumidification heat pump unit to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0021] See also Figure 1-4The utility model provides a variable frequency swimming pool constant temperature dehumidification heat pump unit, including a return air duct 1 fixedly connected to the unit, a plurality of air inlets 2 are provided at the bottom of the return air duct 1, a servo motor 3 is fixedly connected to one side of the return air duct 1, a bidirectional threaded rod 6 is fixedly connected to the output shaft of the servo motor 3, a rotating plate 4 is fixedly sleeved on one end of the bidirectional threaded rod 6 on one side of the servo motor 3, and two symmetrical connecting columns 5 are fixedly connected to the rotating plate 4 on the side away from the outer surface of the servo motor 3, the bidirectional threaded rod 6 is threadedly sleeved on the outer surfaces of both ends of the inner side of the return air duct 1 with threaded connecting blocks 9, the outer surfaces of the two threaded connecting blocks 9 are fixedly sleeved with connecting rings 8, and one of the two connecting rings 8 Two symmetrical limit blocks 10 are fixedly connected to the sides, and two stacked slide grooves are provided on the inner wall of the return air duct 1. Four limit blocks 10 are symmetrically slidably arranged in pairs inside the two slide grooves. The outer surfaces of the two connecting rings 8 are provided with rotation grooves 19, and scraping rings 17 are rotatably arranged on the two rotating grooves 19. The two scraping rings 17 are provided with two symmetrical elastic mechanisms, and the four elastic mechanisms are fixedly connected with plug blocks 16. The surface of the return air duct 1 is provided with a plurality of sockets 20, and the four plug blocks 16 are elastically arranged inside the plurality of sockets 20. When the return air duct 1 returns air through the plurality of air inlets 2, if water droplets or impurities are generated on the inner wall of the return air duct 1, the scraping rings 17 are opened to prevent the return air duct 1 from being damaged. Servo motor 3, at this time, the bidirectional threaded rod 6 will rotate, and the rotation of the bidirectional threaded rod 6 drives the two threaded connection blocks 9 to move toward or away from each other. Since a connecting ring 8 is fixedly sleeved on the two threaded connection blocks 9, and two limit blocks 10 sliding inside the two slide grooves are fixedly connected to the two connection rings 8, the two threaded connection blocks 9 will slide inside the return air duct 1 instead of rotating. At the same time, the rotation of the bidirectional threaded rod 6 drives the rotating plate 4 to rotate, and the rotating plate 4 drives the two connection columns 5 to rotate, and the four sleeve blocks 11 are respectively slidably sleeved on the two connection columns 5. When the two connection columns 5 rotate, the four sleeve blocks 11 will rotate, and the four sleeve blocks 11 are fixedly connected to the Some groove blocks 18 will rotate on the two rotating grooves 19 respectively, providing conditions for the two sets of blocks 11 on the same side to drive a scraping ring 17, a total of two scraping rings 17 to rotate. In summary, when the two-way threaded rod 6 and the two connecting columns 5 rotate, the two connecting rings 8 will move toward or away from each other, and when the two scraping rings 17 rotate, they will synchronously drive the scraping ring 17 to move toward or away from each other inside the return air duct 1, so as to utilize the rotation and the toward or away movement of the scraping ring 17 to scrape the water droplets inside the return air duct 1 and remove impurities, thereby avoiding the adhesion of water droplets and impurities on the water droplets to the inner wall of the return air duct 1, thereby causing the return air effect to deteriorate and increasing the difficulty of subsequent air purification.
[0022] Two elastic mechanisms are provided on the two scraping rings 17, and plug blocks 16 are provided on the elastic mechanisms. When the two scraping rings 17 move toward or away from each other and rotate, the two plug blocks 16 on the two scraping rings 17 will encounter multiple sockets 20 on the inner wall of the return air duct 1. The elastic spring 13 inside each sleeve 12 will push the pressing piece 14 and the plug column 15 to drive the plug block 16 to be inserted into the inside of the socket 20, and knock and vibrate the inner wall of the return air duct 1. By continuously reciprocating the multiple plug blocks 16 with the multiple sockets 20, the efficiency of water droplets and impurities being separated from the inner wall of the return air duct 1 is improved through multiple knocking and vibration.
[0023] Furthermore, arc surfaces are provided at both ends of the plug block 16, and multiple plug blocks 16 elastically slide on the outer surface of the scraping ring 17. The setting of the arc surfaces facilitates the active connection of multiple plug blocks 16 with multiple sockets 20 when the two scraping rings 17 move toward, away from and rotate.
[0024] Furthermore, the scraping ring 17 is a circular ring, and the outer surface of the scraping ring 17 fits with the inner wall of the return air duct 1 , which facilitates the scraping work of the two scraping rings 17 on the inner wall of the return air duct 1 .
[0025] It should be noted that in the above device, the width of the sleeve block 11 is smaller than the width of the connecting ring 8. In this way, when the four limit blocks 10 are respectively fixed to the two connecting rings 8 in pairs, when the two threaded connecting blocks 9 rotate, the sliding connection between the four limit blocks 10 and the two slide grooves can prevent the two connecting rings 8 from rotating following the rotation of the bidirectional threaded rod 6.
[0026] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
[0028] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
