The frequency conversion controller is an electronic device used to adjust the speed of the motor. It controls the speed of the motor by changing the power supply frequency and voltage. In the air-energy water heater, the frequency conversion controller is usually used to control the speed of the compressor to adjust the flow rate of the refrigerant and the operating status of the compressor, thereby realizing the adjustment of the heating or cooling effect of the water heater.

[0003] The frequency conversion controller of the existing air-energy water heater is generally set on the wall of the room and is convenient for control and display, so that the data can be observed and manipulated intuitively. The frequency conversion controller is generally installed on the wall with a base plate by screws. Some are embedded in the wall, and some are protruding. Then the frequency conversion controller is clamped on the base plate by a plastic tough buckle, or it can be fixed to the base plate by screws. If it is a buckle, it is necessary to pry the frequency conversion controller outward to squeeze the buckle and bend it to deform to separate it from the frequency conversion controller. If the operation is improper, the buckle will break. If it is fixed with screws, it needs to be removed with a screwdriver, which makes the removal process slower. Utility Model Content

[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] See also Figures 1 to 4 In an embodiment of the utility model, a frequency conversion controller for an air-energy water heater that is easy to install includes an outdoor unit 1, an air-energy water heater body 2 and a frequency conversion controller body 3. The frequency conversion controller is arranged on a wall in a room, the housing is connected to the air-energy water heater body 2, the frequency conversion controller is connected to the air-energy water heater, and grooves 20 are provided on both sides of the frequency conversion controller body 3 for convenient finger holding to hold the frequency conversion controller body 3.

[0021] A backplane box 4 is provided on the indoor wall by screws, and the backplane box 4 is embedded in the interior of the indoor wall. Two groups of partitions 5 are vertically fixed inside the backplane box 4, and docking grooves 6 are opened on the two groups of partitions 5 to limit the card block 9. The positions of the two groups of partitions 5 facing away from the connecting grooves 6 are movably provided with connecting card bodies 7, and the connecting card bodies 7 are fixed to the side of the frequency conversion controller body 3. A card slot 8 is opened on the side of the connecting card body 7 close to the partition 5. A rubber layer 19 is provided on the inner wall of the card slot 8 for filling the gap between the card slot 8 and the card block 9, so that the frequency conversion controller body 3 is not easily shaken, and a card block 9 is movably provided inside the docking groove 6. The number of card blocks 9 is four, and every two card blocks 9 form a group. The card block 9 is movably connected to the inside of the card slot 8. A connecting rod 10 is fixed on the surface, and the opposite surfaces of a group of card blocks 9 are fixedly connected to the two ends of the connecting rod 10. Third springs 21 are fixed on the two sides of the inner wall of the back box 4 corresponding to the middle position of the connecting rod 10. The other end of the third spring 21 passes through the partition 5 and is movably connected to the surface of the connecting rod 10. There are two third springs 21. The third spring 21 is used to squeeze the connecting rod 10 so that the connecting rod 10 squeezes the connecting rod 10 after the elastic force of the first spring 14 is reduced, thereby moving the connecting rod 10 to drive the card block 9 away from the card slot 8, so as to achieve the purpose of separating the card block 9 from the card slot 8 on the connecting card body 7. The elastic force of the two third springs 21 is less than the elastic force of the first spring 14. Under the action of the first spring 14, the two connecting rods 10 are squeezed. 10 move away from each other and drive the card block 9 to be stuck in the inside of the card slot 8 through the docking slot 6. A movable plate 11 perpendicular to the connecting rod 10 is provided at the middle position of the connecting rod 10. A limit plate 12 movably sleeved on the surface of the movable plate 11 is vertically fixed to the bottom of the inner wall of the back plate box 4. The limit plate 12 mainly functions to limit the movable plate 11 so that the movable plate 11 can only move horizontally. A baffle 13 is fixed on the side of the movable plate 11 away from the connecting rod 10. In order to increase the contact area with the first spring 14 of the baffle 13, the elastic force of the first spring 14 can be improved. The surface of the baffle 13 is fixed with a first spring 14, and a pull ring 15 is movably sleeved on the surface of the first spring 14. A pull rod 16 is fixed to the bottom of the pull ring 15. The bottom end of the pull rod 16 passes through the back of the back plate box 4 And it extends to the bottom of the back box 4. A protrusion 17 is provided on the surface of the pull rod 16 near the pull ring 15. The surface of the pull rod 16 is located between the protrusion 17 and the bottom of the inner wall of the back box 4 and is movably sleeved with a second spring 18. In order to facilitate the pull rod 16 to quickly return to its original position, the elastic force of the second spring 18 is the same as the elastic force of the first spring 14. When installing, the frequency conversion controller body 3 is directly held by hand to make it close to the position of the connecting card body 7 of the back box 4. After the connecting card body 7 is inserted into the back box 4, the card block 9 is squeezed and contracted. When the card slot 8 reaches the position of the card block 9, the card block 9 is connected with the card slot 8 by the elastic force of the first spring 14, thereby stabilizing the connecting card body 7 and then stabilizing the frequency conversion controller body 3. When the frequency conversion controller body 3 needs to be removed,First, pull the pull rod 16 downward to engage the second spring 18 and drive the pull ring 15 downward. The downward movement of the pull spring will drive the first spring 14 in the squeezed state. The downward movement of the pull ring 15 drives the first spring 14 to bend and reduce the elastic force. At this time, the third spring 21 will squeeze the connecting rod 10. Through the above steps, the card block 9 is separated from the card slot 8. After separation, move the frequency conversion controller body 3 in the opposite direction to drive the connecting card body 7 to separate from the back box 4. The frequency conversion controller body 3 can be quickly and easily removed, achieving the purpose of convenient installation and quick removal of the frequency conversion controller body 3, greatly reducing the steps of installing and removing the frequency conversion controller, while reducing the operation time, and greatly improving the efficiency of installation and removal.
