Air conditioner with noise reduction device

Abstract

This utility model discloses an air conditioner with a noise reduction device, comprising an outdoor unit; a bracket for fixing a main frame to a wall or base, and a secondary frame for supporting the outdoor unit; and a noise reduction mechanism including a shock absorber disposed between the secondary frame and the outdoor unit, a steel cable connecting the two secondary frames, and a counterweight suspended from the steel cable. This utility model provides an air conditioner with a noise reduction device. When the outdoor unit is operating, the vibration it generates is reduced by the shock absorber, thereby reducing the vibration of the secondary frame. When the secondary frame vibrates, the vibration is transmitted to the counterweight through the steel cable, causing the counterweight to sway, thus counteracting the vibration and further reducing it, thereby reducing resonance and lessening noise caused by vibration.

Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to air conditioners with noise reduction devices. Background Technology

[0002] Air conditioner outdoor units are typically mounted on building walls or air conditioning installation platforms using brackets. When the outdoor unit operates, it vibrates, creating resonance with the bracket and transmitting this vibration to the wall, thus generating noise. One way to reduce this noise is to mitigate the resonance. Utility Model Content

[0003] To solve the above problems, this technical solution provides an air conditioner with a noise reduction device.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] Air conditioners with noise reduction devices, including

[0006] Air conditioner outdoor unit;

[0007] The bracket includes a main frame for fixing to a wall or base, and a secondary frame for supporting the outdoor unit of the air conditioner.

[0008] The noise reduction mechanism includes a shock absorber disposed between the sub-frame and the outdoor unit of the air conditioner, a steel cable connecting the two sub-frames, and a counterweight suspended on the steel cable.

[0009] As described above, in an air conditioner with a noise reduction device, the two steel cables are connected in a cross shape to the front and rear ends of the two sub-frames, and the counterweight is suspended at the intersection of the two steel cables.

[0010] As described above, in an air conditioner with a noise reduction device, the end of the steel cable is provided with a threaded post, and the subframe is provided with a mounting hole for inserting the threaded post. The threaded post cooperates with a nut, and the distance between its insertion into the mounting hole is adjusted to adjust the tension of the steel cable.

[0011] The air conditioner with noise reduction device as described above also includes a fall protection mechanism, which includes a fixing hole on the main frame and a connecting cable connecting the fixing hole and the counterweight.

[0012] As described above, in an air conditioner with a noise reduction device, the main frame is hinged to the sub-frame, and the main frame has a cavity for the sub-frame to be embedded in.

[0013] As described above, in an air conditioner with a noise reduction device, the main frame and the sub-frame are fixedly connected, and a shock-absorbing pad is provided between the main frame and the wall.

[0014] As described above, the air conditioner with a noise reduction device has a base frame on the outdoor unit. The two ends of the shock absorber pass through the base frame and the sub-frame respectively and are fixed by nuts. A washer is provided between the nut and the base frame or the sub-frame.

[0015] The beneficial effects of this application are:

[0016] This invention provides an air conditioner with a noise reduction device. When the outdoor unit of the air conditioner is working, the vibration it generates is reduced by a shock absorber, thereby reducing the vibration of the sub-frame. When the sub-frame vibrates, it is transmitted to the counterweight through a steel cable, causing the counterweight to sway, thereby canceling out the vibration and further reducing the vibration, thus reducing the generation of resonance and reducing the noise caused by vibration.

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0018] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Air conditioners with noise reduction devices, including

[0021] Air conditioner outdoor unit 1;

[0022] The bracket 2 consists of a main frame 21 for fixing to a wall or base, and a secondary frame 22 for supporting the outdoor unit 1 of the air conditioner.

[0023] The noise reduction mechanism 3 includes a shock absorber 31 disposed between the sub-frame 22 and the air conditioner outdoor unit 1, a steel cable 32 connecting the two sub-frames 22, and a counterweight 33 suspended on the steel cable 32.

[0024] This invention provides an air conditioner with a noise reduction device. When the outdoor unit of the air conditioner is working, the vibration it generates is reduced by a shock absorber, thereby reducing the vibration of the sub-frame. When the sub-frame vibrates, it is transmitted to the counterweight through a steel cable, causing the counterweight to sway, thereby canceling out the vibration and further reducing the vibration, thus reducing the generation of resonance and reducing the noise caused by vibration.

[0025] Furthermore, as a preferred embodiment of this solution and not a limitation, the two steel cables 32 are connected in a crisscross pattern to the front and rear ends of the two sub-frames 22, and the counterweight 33 is suspended at the intersection of the two steel cables 32. The steel cables can tighten the two sub-frames, making them less prone to swaying, while also providing support for the counterweight. The counterweight is fixed to the steel cables and can accept the vibration transmitted by the steel cables.

[0026] Furthermore, as a preferred embodiment of this solution and not a limitation, the end of the steel cable 32 is provided with a threaded post 321, and the subframe 22 is provided with a mounting hole 221 for inserting the threaded post 321. The threaded post 321 cooperates with a nut, and the distance of its insertion into the mounting hole 221 is adjusted to adjust the tension of the steel cable 32. This can accommodate installation errors.

[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a fall arrest mechanism 4, which includes a fixing hole 41 provided on the main frame 21 and a connecting cable 42 connecting the fixing hole 41 and the counterweight 33. This prevents falls that could lead to accidents.

[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, the main frame 21 and the sub-frame 22 are hinged, and the main frame 21 is provided with a cavity 211 for the sub-frame 22 to be inserted. This facilitates folding and saves space.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the main frame 21 and the sub-frame 22 are fixedly connected, and a shock-absorbing pad 34 is provided between the main frame 21 and the wall to increase the shock absorption effect.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the outdoor unit 1 of the air conditioner is provided with a base frame 11, and the two ends of the shock absorber 31 pass through the base frame 11 and the sub-frame 22 respectively, and are fixed by nuts. A washer 35 is provided between the nut and the base frame 11 or the sub-frame 22 to increase the shock absorption effect.

[0031] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
