Technical Field

[0001] The utility model belongs to the technical field of water heater end covers, in particular to an air energy water heater with a noise reduction end cover. Background Art

[0002] Air-source water heaters, also known as air-source heat pump water heaters, absorb low-temperature heat from the air, vaporize it through a fluorine medium, compress it through a compressor, increase the pressure and temperature, and then convert it into water through a heat exchanger to heat the water. The compressed high-temperature heat energy is then used to heat the water.

[0003] The existing air energy water heater end cover cannot play a role in noise reduction, resulting in the air energy water heater generating noise during use, affecting the user experience. To this end, we propose an air energy water heater with a noise reduction end cover. Utility Model Content

A hexagonal shaft is fixedly connected to the inner wall of the end cover body. The hexagonal shaft passes through the frame and the sound insulation cotton and is used to fix the installation angle of the frame and the sound insulation cotton.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model reduces the noise of the water heater body through the sound insulation cotton, and at the same time uses the hexagonal axis to limit the installation angle of the skeleton, so that each leg of the skeleton can be aligned with the fixing component installed on the inner wall of the end cover body. The skeleton is firmly fixed to the inner wall of the end cover body through the fixing component, which is convenient for fixing and replacing the sound insulation cotton.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example 1

[0020] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the air-energy water heater with a noise reduction end cover includes a water heater body 1 and an end cover body 2 installed at the end of the water heater body 1. The inner wall of the end cover body 2 is installed with a detachable frame 7 through a fixing component. Sound insulation cotton 8 for noise reduction is arranged between the frame 7 and the end cover body 2. The inner wall of the end cover body 2 is fixedly connected with a hexagonal shaft 3, which passes through the frame 7 and the sound insulation cotton 8 and is used to fix the installation angle of the frame 7 and the sound insulation cotton 8.

[0021] It should be noted that the end cover body 2 is installed with a water inlet pipe 21 and a water outlet pipe 22 , and the sound insulation cotton 8 is provided with a through hole whose size is adapted to the water inlet pipe 21 and the water outlet pipe 22 .

[0022] Specifically, the water heater body 1 is noise-reduced by the sound-insulating cotton 8, and the hexagonal shaft 3 is used to limit the installation angle of the skeleton 7, so that each leg of the skeleton 7 can be aligned with the fixing component installed on the inner wall of the end cover body 2. The skeleton 7 is firmly fixed to the inner wall of the end cover body 2 through the fixing component, which facilitates the fixation and replacement of the sound-insulating cotton 8.

[0023] like Figure 2 、 Figure 3 and Figure 4 As shown, one end of the hexagonal shaft 3 away from the end cover body 2 is fixedly connected to a threaded rod 4, and the threaded rod 4 is threadedly connected to a threaded sleeve 5. The outer ring of the threaded sleeve 5 is fixed with a rubber sleeve 6, and the rubber sleeve 6 is in conflict with the frame 7.

[0024] Specifically, the threaded rod 4 is matched with the threaded sleeve 5 , and the skeleton 7 is firmly fixed in the hexagonal shaft 3 , and the rubber sleeve 6 is used to prevent the threaded sleeve 5 from causing wear to the skeleton 7 .

[0025] Example 2

[0026] like Figure 3 and Figure 4 As shown, the air-energy water heater with a noise reduction end cover, compared with Example 1, the fixing component of this embodiment includes a positioning shaft 9 fixed on the inner wall of the end cover body 2, the outer ring of the positioning shaft 9 is rotatably sleeved with a ring 10, the outer wall of the ring 10 is fixedly connected with a baffle 11, and the skeleton 7 is provided with a positioning hole 71; the positioning hole 71 includes a circular portion and a rectangular portion, the circular portion is adapted to the size of the positioning shaft 9, and the rectangular portion is adapted to the size of the baffle 11.

[0027] Specifically, the baffle 11 can rotate around the positioning shaft 9. After the positioning shaft 9 and the baffle 11 pass through the positioning hole 71, the baffle 11 is rotated so that it is misaligned with the rectangular part of the positioning hole 71. At this time, the skeleton 7 cannot be separated from the end cover body 2, and the sound insulation cotton 8 can be firmly fixed in the inner wall of the end cover body 2. When the baffle 11 is aligned with the rectangular part of the positioning hole 71, the skeleton 7 can be disassembled from the end cover body 2.

[0028] like Figure 3 As shown, one end of the positioning shaft 9 away from the end cover body 2 is fixedly connected to an elastic piece 12 , and one side of the elastic piece 12 is fixedly connected to an anti-sliding block 13 , which is in contact with the baffle 11 .

[0029] Specifically, the elastic piece 12 pushes the anti-sliding block 13 so that the baffle 11 will not rotate around the positioning axis 9 in the absence of external interference.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
