Description

Technical Field

[0001] The utility model belongs to the technical field of air source heat pumps, in particular to a noise reduction and silencing device for air source heat pumps. Background Art

[0002] Air source heat pumps use air as a heat source, transferring heat from outdoor air to indoor air in winter and transferring indoor heat to outdoor in summer.

[0003] During use, the existing air source heat pump needs to use a fan to exchange ventilation with the outside air. During the ventilation process, a large amount of dust will adhere to the surface of the filter that protects the fan. Long-term ventilation will affect the use efficiency of the air source heat pump. The dust on the surface of the filter cannot be automatically cleaned and needs to be manually scrubbed, wasting manpower.

[0004] For example, (authorization announcement number CN219318787U) an air source heat pump noise reduction and silencer device, when in fixed use, by rotating the screw rod, the tension rod connected to the screw rod side wall drives the lower clamp plate to move upward, and the upward moving lower clamp plate and the upper clamp plate fixed to the side wall of the silencer box fix the connecting shaft of the side wall of the noise reduction plate, thereby realizing the rapid fixation of the noise reduction plate. This device has this problem: during use, the air source heat pump is placed inside the silencer device, and the silencer device needs to be disassembled to clean the dust on the surface, which reduces the use efficiency.

[0008] In a further embodiment, a top frame is fixed to the top of one of the sound insulation covers, and a fixing nail is threadedly connected to the top of the top frame.

[0009] In a further embodiment, a plug-in plate that can be inserted into the top frame is fixed to the top of another of the sound insulation covers, and a threaded groove is provided at the top of the plug-in plate.

[0010] In a further embodiment, two mounting plates are mounted on the sides of the bottom frame.

[0011] In a further embodiment, a mounting block with a hollow structure is fixed to the sides of the two sound insulation covers that are away from each other.

[0012] In a further embodiment, a fixing block is fixed inside each of the two mounting blocks.

[0013] In a further embodiment, second telescopic rods are installed on both sides of the two fixing blocks.

[0014] In a further embodiment, a clamping plate is installed on one side of the moving portion of each of the two second telescopic rods.

[0015] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

A soundproof cover 2 for reducing and silencing the air source heat pump is fixed between the two vertical plates 5. The linear motor 12 arranged on the side of the fixed plate 13 drives the two movable plates 23 on the outer periphery of the bidirectional screw rod to move toward each other, thereby driving the vertical plates 5 inside the movable groove 11 to move synchronously, so that the two soundproof covers 2 are displaced to wrap the air source heat pump body 10 at the upper end of the mounting seat 14, and the soundproof cover 2 is used to reduce and silence the air source heat pump body 10 to prevent damage to the air source heat pump.

[0031] At the same time, during the synchronous displacement of the two partition covers 2, the connecting column 18 arranged inside the mounting groove 3 is used, through the connecting plate 17 arranged on the side of the connecting column 18, and the first telescopic rod 19 on the side of the connecting plate 17 is used to adjust the brush plate 23 to gradually approach the surface of the filter screen, so as to automatically brush off the dust on the surface of the filter screen, so as to facilitate the cleaning of the dust on the surface of the filter screen during the noise reduction and silencing process, thereby improving the use efficiency. The vertical sides of the two sound insulation covers 2 are provided with mounting grooves 3, and the inner walls of the two mounting grooves 3 are connected with connecting columns 18.
