[0002] An air conditioner, also called an air regulator, refers to a device that adjusts and controls parameters such as the temperature, humidity, and flow rate of the air environment in a building or structure through artificial means. An air conditioner usually consists of structures such as a compressor, a condenser, an evaporator, and a one-way valve capillary tube assembly. When the outdoor unit of an air conditioner is working, it will emit a relatively large noise, and generally noise reduction is carried out on the outdoor unit of the air conditioner when installing it.

[0003] When installing an air conditioner inside a house, the outdoor unit of the air conditioner is generally installed outside the house through a steel structure frame. When the outdoor unit of the air conditioner is working, it will vibrate, and the rotation of the cooling fan of the outdoor unit of the air conditioner will also generate noise. The noise generated by the vibration of the outdoor unit of the air conditioner will transmit noise to the inside of the house through the steel structure frame fixed on the outer wall of the house. Therefore, a ventilation air conditioner noise reduction device that can reduce the noise generated by the vibration of the outdoor unit of the air conditioner is needed.

[0004] In view of this, the utility model provides a ventilation air conditioner noise reduction device. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages and provide a ventilation air conditioner noise reduction device that can reduce the noise generated by the vibration of the outdoor unit of the air conditioner.

[0006] By using a placement block and a shock pad, the contact area between the outdoor unit body of the air conditioner and the placement rack is reduced, and then the vibration of the outdoor unit body of the air conditioner is weakened through the shock pad, reducing the situation of noise transmission from the vibration of the outdoor unit body of the air conditioner to the inside of the house. At the same time, the sound insulation strip on the inner wall of the sleeve ring weakens the noise emitted from the heat dissipation air outlet of the outdoor unit body of the air conditioner.

[0007] Therefore, the utility model provides a ventilation air conditioner noise reduction device, which includes an outdoor unit body of the air conditioner. A placement rack for installing the outdoor unit body of the air conditioner is installed at the bottom of the outdoor unit body of the air conditioner. A shock pad for damping the bottom of the outdoor unit body of the air conditioner is installed at the top of the placement rack. A sliding component that slides on the top of the placement rack is installed at the bottom of the shock pad. A noise reduction component that is sleeved on the heat dissipation air outlet of the outdoor unit body of the air conditioner is slidably installed at the top of the placement rack.

[0008] As a further improvement of this technical solution, the sliding component includes a chute opened at the top of the placement rack. Two placement blocks are slidably installed inside the chute, and the two placement blocks slide inside the chute to adjust to a suitable distance for supporting and placing the outdoor unit body of the air conditioner.

[0009] As a further improvement of the technical solution, after the two placement blocks are adjusted to an appropriate distance, they are fixedly installed at the bottom of the shock pad to buffer and weaken the vibration of the installed air conditioner outdoor unit body.

[0010] As a further improvement of the technical solution, the noise reduction component includes a first sliding block slidably installed inside the chute. A collar sleeving the heat dissipation air outlet of the air conditioner outdoor unit body is fixedly installed at the top of the first sliding block. A fitting ring for tightly installing the collar on the air conditioner outdoor unit body is installed on one side of the collar close to the air conditioner outdoor unit body. A sound insulation strip for sound insulation of the heat dissipation air outlet of the air conditioner outdoor unit body is installed on the inner wall of the collar.

[0011] As a further improvement of the technical solution, there are two placement racks, and the two placement racks are installed on both sides of the bottom of the air conditioner outdoor unit body for support and fixation. A second sliding block for installing the collar is fixedly installed on the outer surface of the collar.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] In this ventilation air conditioner noise reduction device, the four placement blocks on the two placement racks slide in the chute to an appropriate distance for installing the air conditioner outdoor unit body, so that the bottom of the air conditioner outdoor unit body is installed on the placement rack through the shock pad. The bottom of the air conditioner outdoor unit body is installed and placed through the four placement blocks, reducing the contact area between the air conditioner outdoor unit body and the placement rack. Then, the vibration of the air conditioner outdoor unit body is weakened by the shock pad, reducing the noise transmitted from the vibration of the air conditioner outdoor unit body to the interior of the house. Further, by moving the first sliding block and the second sliding block in the chutes on the two placement racks, the collar is sleeved on the heat dissipation air outlet of the air conditioner outdoor unit body, and the noise emitted from the heat dissipation air outlet of the air conditioner outdoor unit body is weakened by the sound insulation strip on the inner wall of the collar, achieving the effect of noise reduction.

[0020] When installing an air conditioner inside a house, the outdoor unit of the air conditioner is generally installed outside the house through a steel structure frame. When the outdoor unit of the air conditioner works, it will vibrate, and the rotation of the cooling fan of the outdoor unit of the air conditioner will also generate noise. The noise generated by the vibration of the outdoor unit of the air conditioner will transmit noise to the inside of the house through the steel structure frame fixed on the outer wall of the house. There is a need for a ventilation air conditioner noise reduction device that can reduce the noise generated by the vibration of the outdoor unit of the air conditioner.

[0021] As Figure 1-2 shown, the device includes an air conditioner outdoor unit body 1. A placing rack 2 for installing the air conditioner outdoor unit body 1 is installed at the bottom of the air conditioner outdoor unit body 1. A shock pad 3 for damping the bottom of the air conditioner outdoor unit body 1 is installed on the top of the placing rack 2. A sliding assembly 4 that slides on the top of the placing rack 2 is installed at the bottom of the shock pad 3. A noise reduction assembly 5 sleeved on the heat dissipation air outlet of the air conditioner outdoor unit body 1 is slidably installed on the top of the placing rack 2.

[0022] First, the specific structure of the sliding assembly 4 is disclosed. The sliding assembly 4 includes a chute 401 opened on the top of the placing rack 2. Two placing blocks 402 are slidably installed inside the chute 401. The two placing blocks 402 slide inside the chute 401 to adjust the distance for supporting and placing the air conditioner outdoor unit body 1 to a suitable position. After the two placing blocks 402 are adjusted to a suitable distance, they are fixedly installed at the bottom of the shock pad 3 to buffer and weaken the vibration of the installed air conditioner outdoor unit body 1.

[0023] The improvement of this embodiment lies in that: the distance can be adjusted inside the chute 401 by the two placing blocks 402 according to the different sizes of the air conditioner outdoor unit body 1. After the bottom of the air conditioner outdoor unit body 1 is placed on the shock pad 3 on the top of the placing blocks 402, the shock pad 3 is made of rubber material, which can buffer and weaken the vibration of the air conditioner outdoor unit body 1. Then, it is supported and placed by the placing rack 2 at the bottom of the placing blocks 402, so that only the placing blocks 402 are in contact between the bottom of the air conditioner outdoor unit body 1 and the placing rack 2, the contact surface is reduced, and the vibration of the air conditioner outdoor unit body 1 can be weakened by the shock pad 3, so that the noise transmitted to the inside of the house is reduced, solving the problem in the prior art that the air conditioner outdoor unit body 1 transmits vibration noise to the inside of the house through the placed steel structure placing rack 2.

[0024] Due to the problem of noise generated by the rotation of the fan blade of the motor at the heat dissipation air outlet of the air conditioner outdoor unit body 1 in the prior art, therefore, Figure 1 and Figure 3 show the second embodiment of the present invention.

[0025] The specific structure of the noise reduction component 5 is disclosed again. The noise reduction component 5 includes a first sliding block 501 slidably installed inside the chute 401. A collar 502 sleeving the heat dissipation air outlet of the air conditioner outdoor unit body 1 is fixedly installed on the top of the first sliding block 501. A fitting ring 503 for tightly installing the collar 502 on the air conditioner outdoor unit body 1 is installed on one side of the collar 502 close to the air conditioner outdoor unit body 1. A sound insulation strip 504 for sound insulation of the heat dissipation air outlet of the air conditioner outdoor unit body 1 is installed on the inner wall of the collar 502. There are two placement racks 2, and the two placement racks 2 are installed on both sides of the bottom of the air conditioner outdoor unit body 1 for support and fixation. A second sliding block 6 for installing the collar 502 is fixedly installed on the outer surface of the collar 502.

[0026] The improvement of this embodiment lies in that: after the air conditioner outdoor unit body 1 is installed on the placement rack 2, the first sliding block 501 and the second sliding block 6 slide in the two chutes 401 respectively. The first sliding block 501 and the second sliding block 6 are respectively slidably installed in the two chutes 401 through the clamping blocks extending outward on the outside, so that the collar 502 can move back and forth. The collar 502 is moved to the heat dissipation air outlet of the air conditioner outdoor unit body 1, so that the fitting ring 503 outside the collar 502 installs the collar 502 on the heat dissipation air outlet of the air conditioner outdoor unit body 1 through the adhesive liquid. The sound insulation strip 504 installed on the inner wall of the collar 502 weakens the transmission of the sound emitted from the heat dissipation air outlet of the air conditioner outdoor unit body 1. The collar 502 can make the air flow blown out from the air outlet more concentrated and smooth, change the air flow characteristics at the air outlet, reduce the noise generated by the direct impact of the air flow on the external environment, and the sound insulation strip 504 can further reduce the weakened noise, achieving the effect of weakening and reducing the noise emitted from the heat dissipation air outlet of the air conditioner outdoor unit body 1, and solving the problem of noise emitted from the heat dissipation air outlet of the air conditioner outdoor unit body 1 existing in the prior art.

[0027] In summary, the working principle of this solution is as follows:

[0028] The four placement blocks 402 on the two placement racks 2 slide in the chute 401 to a suitable distance for installing the air conditioner outdoor unit body 1, so that the bottom of the air conditioner outdoor unit body 1 is installed on the placement rack 2 through the shock-absorbing pad 3. The bottom of the air conditioner outdoor unit body 1 is installed and placed through the four placement blocks 402, reducing the contact area between the air conditioner outdoor unit body 1 and the placement rack 2. Then, the shock of the air conditioner outdoor unit body 1 is weakened through the shock-absorbing pad 3, reducing the noise transmitted from the vibration of the air conditioner outdoor unit body 1 to the interior of the house; then, the first sliding block 501 and the second sliding block 6 move in the chute 401 on the two placement racks 2, and the collar 502 is sleeved on the heat dissipation air outlet of the air conditioner outdoor unit body 1. The noise emitted from the heat dissipation air outlet of the air conditioner outdoor unit body 1 is weakened through the sound insulation strip 504 on the inner wall of the collar 502, achieving the effect of noise reduction.
