Description

Technical Field

[0002] A variable frequency chiller is a refrigeration device that uses variable frequency technology to adjust the operating speed of the compressor. It can automatically adjust the cooling capacity according to actual needs, thereby achieving energy saving. The noise generated by the variable frequency chiller during operation may affect the surrounding environment, especially in places that require a quiet environment. Therefore, a noise reduction structure is required for the variable frequency chiller during operation.

[0003] According to the utility model of authorization announcement number CN213627912U, a noise reduction device for a compressor unit is disclosed, including: a compressor body, a base, and a mounting cover. The compressor body and the mounting cover are both installed above the base, and the compressor body is located inside the mounting cover. Although the device uses a sealing rubber bag to stick on the inside of the mounting cover to form a noise reduction device, and reduces the noise generated during the practical operation of the chiller through the noise reduction device and the shock-absorbing gasket, the device does not have the ability to be easily disassembled and assembled. The installation and disassembly process is very cumbersome and requires a lot of operator time. At the same time, relying on sealing like capsule pasting cannot ensure the firmness of the noise reduction device during operation, and it is easy to cause noise leakage due to cracking, which reduces the use effect of the noise reduction structure for the chiller. To this end, we provide a noise reduction structure for a variable frequency chiller to solve the above problems. Utility Model Content

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] The present embodiment provides a noise reduction structure for a variable frequency chiller, which is used to reduce the noise of the variable frequency chiller. The noise of the variable frequency chiller body 201 is degraded by the sound insulation board 205 in the noise reduction mechanism 2. The mounting block 203 is driven by rotating the bidirectional threaded rod 202 to clamp the variable frequency chiller body 201, and the sound insulation board 205 can be quickly installed by using the placement groove 204. At the same time, the limit on the sound insulation board 205 can be released by pulling the limit rod 207, and then it can be quickly disassembled. The bidirectional threaded rod 202 is then reversed to move the mounting block 203 away, so that the ability to load and unload is convenient, and the sound insulation board 205 can be prevented from detaching when blocking noise, effectively improving the use effect of the device.

[0022] Reference Figure 1 and Figure 2 A noise reduction structure for a variable frequency chiller includes a support plate 1. A noise reduction mechanism 2 is provided inside and above the support plate 1. The noise reduction mechanism 2 includes a variable frequency chiller body 201. The variable frequency chiller body 201 is located above the support plate 1. The inside of the support plate 1 is rotatably connected to a bidirectional threaded rod 202. The left end of the bidirectional threaded rod 202 is fixedly connected to a rotating handle 210. The outer surface of the rotating handle 210 is fixedly connected to a grip 211. The cooperation of the rotating handle 210 and the grip 211 can provide a good force point for the bidirectional threaded rod 202, thereby increasing the convenience when the bidirectional threaded rod 202 needs to be rotated, thereby improving the convenience of the device when in use.

[0023] Reference Figure 2 The outer surface of the bidirectional threaded rod 202 is threadedly connected to two mounting blocks 203. The outer surface of the bidirectional threaded rod 202 is sleeved with an auxiliary bearing 212. The auxiliary bearing 212 is embedded in the inside of the support plate 1. The auxiliary bearing 212 can reduce the friction generated by the bidirectional threaded rod 202 during rotation, making the bidirectional threaded rod 202 more sensitive when rotating. At the same time, it can also reduce the wear rate of the bidirectional threaded rod 202 and increase the durability of the bidirectional threaded rod 202.

[0024] Reference Figure 2 Each mounting block 203 is slidably connected to the inside of the support plate 1. Two placement grooves 204 are provided inside each mounting block 203. A firm block 213 is fixedly connected to the front of each mounting block 203. Each firm block 213 is slidably connected to the inside of the support plate 1. The firm block 213 can move simultaneously with the mounting block 203 and use the friction force generated by itself on the support plate 1 during the movement to improve the stability of the mounting block 203 during movement and prevent jamming.

[0025] Reference Figure 2 and Figure 3Two sound insulation plates 205 are provided on the outer surface of the variable frequency chiller body 201, and each sound insulation plate 205 is slidably connected to the inside of the placement groove 204. The front of one sound insulation plate 205 is fixedly connected to two sliding blocks 206, and the two sliding blocks 206 are slidably connected to the inside of the other sound insulation plate 205. The inside of each mounting block 203 is slidably connected to two limit rods 207, and the ends of each group of limit rods 207 that are away from each other are fixedly connected to a stopper 214, and the sides of the two stoppers 214 that are away from each other are fixedly connected to an auxiliary handle 215. Relying on the cooperation of the stopper 214 and the auxiliary handle 215, a good force position can be provided for the limit rod 207, which increases the convenience when pulling the limit rod 207 and improves the convenience of the device.

[0026] Reference Figure 3 The outer surface of each auxiliary handle 215 is fixedly connected with a reinforcement ring 216, and the ends of the two sets of reinforcement rings 216 that are close to each other are fixedly connected to the side of the block 214 that is away from each other. The reinforcement ring 216 can increase the fixed connection area between the block 214 and the auxiliary handle 215, thereby making the connection between the two parties more secure, preventing the possibility of breakage at the connection after long-term use, and increasing the firmness of the device.

[0027] Reference Figure 3 and Figure 4 The ends of the two groups of limit rods 207 that are close to each other extend to the inside of the sound insulation board 205. The outer surface of each group of limit rods 207 is fixedly connected with a retaining ring 208. The ends of the two groups of retaining rings 208 that are away from each other are fixedly connected with a return spring 209. The ends of the two groups of return springs 209 that are away from each other are fixedly connected to the inner side wall of the mounting block 203. The inner top wall of the support plate 1 is fixedly connected with two groups of dampers 217. The bottom end of each group of dampers 217 is fixedly connected with a buffer block 218. Each group of buffer blocks 218 is slidably connected to the inside of the support plate 1. Through the cooperation of the dampers 217 and the buffer blocks 218, an effective damping effect can be provided for the support plate 1, thereby reducing the shaking generated by the variable frequency chiller body 201 during operation, and further improving the noise reduction effect of the variable frequency chiller body 201.

[0028] Reference Figure 4 The outer surface of each group of buffer blocks 218 is fixedly connected with a stabilizing block 219, and each stabilizing block 219 is slidably connected to the inside of the support plate 1. The stabilizing block 219 can move simultaneously with the buffer block 218 and rely on itself to limit the moving distance of the buffer block 218, thereby improving the protection capability during use.

[0029] Working principle: When in use, first connect the variable frequency chiller body 201 to the power supply. When the variable frequency chiller body 201 needs to be installed with noise reduction, place the variable frequency chiller body 201 on the upper surface of the support plate 1. Then rotate the handle 210 to drive the two-way threaded rod 202 to rotate. At the same time, the auxiliary bearing 212 can increase the sensitivity of the two-way threaded rod 202 during rotation, so that the two mounting blocks 203 are close to each other and clamp the two sides of the variable frequency chiller body 201, thereby fixing the position of the variable frequency chiller body 201. Then insert the sound insulation board 205 into the placement slot 204 and limit it with the limit rod 207. The telescopic ability of the reset spring 209 can improve the effect of the limit rod 207 when limiting. Then, the two sound insulation boards 205 are combined through the sliding block 206, so that the sound insulation board 205 can be quickly installed. At the same time, the damper The damping effect produced by the cooperation of 217 and the buffer block 218 can reduce the shaking generated during the operation of the variable frequency chiller body 201, further increasing the effect of noise reduction. When disassembly is required, pull the two auxiliary handles 215, thereby driving the block 214 and the limit rod 207 to move, so that the limit rod 207 is moved out of the sound insulation board 205, and then the sound insulation board 205 is moved out of the placement groove 204, and the handle 210 is reversed to release the mounting block 203 from the clamping of the variable frequency chiller body 201, thereby realizing the ability of convenient loading and unloading, increasing the convenience during use, and also preventing the sound insulation board 205 from detaching, further improving the effect during use.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
