Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, in particular to a noise reduction structure for a dehumidifier. Background Art

[0002] Dehumidifier, also known as dehumidifier, dryer, dehumidifier, is a device used to reduce the relative humidity in the air. It can be generally divided into two categories: civil dehumidifier and industrial dehumidifier. The compressor plays a core role in the dehumidifier and is the "heart" of the refrigeration system. Its main function is to increase the low-pressure refrigerant gas to high-pressure gas to provide power for the refrigeration cycle. The compressor drives the piston to compress the refrigerant gas through the operation of the motor to change the refrigerant from a low-temperature and low-pressure state to a high-temperature and high-pressure state, thereby realizing a refrigeration cycle of compression-condensation (heat release)-expansion-evaporation (heat absorption). When the compressor is working, due to the effects of gas force, inertia force, friction force and other loads, it may stimulate the vibration of components such as the compressor casing, the entire machine chassis, the piping system and the supporting structure, thereby generating noise. Utility Model Content

[0006] As a further optimization scheme, the buffer assembly includes a bracket, which is installed at the bottom of the inner cavity of the dehumidifier. The upper and lower parts of the bracket are fixedly connected with a group of limit rods, and each group of limit rods has two. The outer wall of the recessed part of the rotating wheel slides and is clamped on the outer wall of the limit rod. The length of the limit rod is shorter than the elastic member. One end of the elastic member is connected to the middle of the bracket, and the other end of the elastic member is connected to the middle of the connecting frame.

[0007] As a further optimization scheme, a sound-absorbing component is installed at the position of the outer wall of the compressor where the limit component is not installed. The sound-absorbing component includes sound-absorbing cotton and a sleeve rod. The sound-absorbing cotton is attached to the outer wall of the compressor. One end of the sleeve rod passes through the sound-absorbing cotton and is connected to the compressor. The outer wall of the other end of the sleeve rod is sleeved with a sleeve.

[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] See also Figure 1-4The utility model provides a technical solution: a noise reduction structure for a dehumidifier, the noise reduction structure is installed on the compressor 2 inside the dehumidifier 1, and multiple groups of noise reduction structures are installed on the outer wall of the compressor 2. The noise reduction structure includes a limit assembly 3, and the limit assemblies are multiple and evenly arranged on the outer wall of the compressor 2; corresponding to the multiple limit assemblies 3, multiple groups of buffer assemblies 4 are provided, and an elastic member 6 is provided between the limit assembly 3 and the buffer assembly 4, and the vibration generated by the compressor 2 is suppressed by the elastic member 6.

[0026] Compressor 2 is the main equipment in dehumidifier 1. Compressor 2 generates airflow to absorb moisture, which is the main source of noise in dehumidifier 1. When compressor 2 vibrates, the shaking force drives limit component 3 to produce a small range of displacement on buffer component 4. The elasticity of elastic part 6 resists the vibration and buffers the vibration force. The vibration force cannot be transmitted to other parts such as the outer casing of dehumidifier 1. Dehumidifier 1 will not generate noise from self-vibration of the body, thereby reducing the noise generated when the dehumidifier is working.

[0027] In some embodiments, the limiting assembly 3 includes a connecting ring 31 , which has two upper and lower connecting rings 31 . The two connecting rings 31 are connected by a connecting frame 32 . There are four connecting frames 32 , corresponding to the position of the buffer assembly 4 . A rotating wheel 33 is installed on each of the four connecting frames 32 .

[0028] The connecting ring 31 is a connecting medium for the limiting assembly to be installed on the compressor 2. Using two connecting rings 31 can increase the stability of the installation on the compressor 2. The connecting frame 32 is used to install the rotating wheel 33, and the rotating wheel 33 slides on the buffer assembly 4 for buffering.

[0029] In some embodiments, the buffer assembly 4 includes a bracket 41, which is installed at the bottom of the inner cavity of the dehumidifier 1. A group of limit rods 42 are fixedly connected to the upper and lower parts of the bracket 41, and each group of limit rods 42 has two. The outer wall of the recessed part of the wheel 33 slides and is clamped on the outer wall of the limit rod 42. The length of the limit rod 42 is shorter than the elastic member (6). One end of the elastic member 6 is connected to the middle of the bracket 41, and the other end of the elastic member 6 is connected to the middle of the connecting frame 32.

[0030] The bracket 41 is placed on the limit rod 42, and the rotating wheel 33 can slide on the outer wall of the limit rod 42 to guide the movement trajectory of the limit assembly 3. The length of the limit rod (42) is shorter than the elastic member 6 to prevent the limit rod 42 from being too long and pressing against the mounting frame 32 during vibration, causing it to get stuck. When the mounting frame 32 moves, it pushes the elastic member 6 to deform, and the elasticity of the elastic member 6 offsets the vibration force on the mounting frame 32.

[0031] In some embodiments, a sound absorbing component 5 is installed at the outer wall of the compressor 2 where the limit component 3 is not installed. The sound absorbing component 5 includes sound absorbing cotton 51 and a sleeve rod 53. The sound absorbing cotton 51 is attached to the outer wall of the compressor 2. The sleeve rod 53 passes through one end of the sound absorbing cotton 51 and is connected to the compressor 2. The outer wall of the other end of the sleeve rod 53 is sleeved with a sleeve 52.

[0032] The sound-absorbing cotton 51 is sleeved on the outer wall of the sleeve rod 53 and connected to the outer wall of the compressor 2. The sleeve 52 is sleeved on the outer wall of the sleeve rod 53 to seal the outer wall of the sleeve rod 53 to prevent the sound-absorbing cotton 51 from falling and fix the installation of the sound-absorbing cotton 51 on the outer wall of the compressor 2.

[0033] In some embodiments, two of the four buffer components 4 are diagonally distributed, and the diagonal arrangement can allow the vibration forces to be relatively offset in the same direction.

[0034] In some embodiments, the rotating wheel 33 is a silent roller, which produces less noise and minimizes noise.

[0035] In some embodiments, the connection between the limit assembly 3 and the buffer assembly 4 lifts the compressor 2 up into the air, and after being suspended in the air, the compressor 2 is prevented from directly contacting the dehumidifier 1 and from vibrating with the casing.

[0036] In some embodiments, the limiting rod 42 is made of polyetheretherketone, which has good wear resistance.

[0037] In some embodiments, the number of the limiting components 3 and the buffer components 4 is at least four, and four can meet the buffering requirements in the vibration direction. Multiple installations have better noise reduction effects.

[0038] In some embodiments, the limiting assembly 3 and the buffer assembly 4 are detachable, and the detachable effect allows for repair and replacement.

[0039] Working principle: When the compressor 2 is working, it generates vibration, which drives the connecting ring 31 at the corresponding position to shake, and the connecting ring 31 drives the connecting frame 32 to move. The connecting frame 32 drives the rotating wheel 33 to move on its corresponding buffer component 4. The rotating wheel 33 slides on the outer wall of the limiting rod 42. At the same time, the mounting frame 32 pushes the elastic member 6 to deform. The elasticity of the elastic member 6 offsets the vibration force on the mounting frame 32. The vibration force generated by the compressor 2 is offset by the cooperation of the limiting component 3 and the buffer component 4, avoiding the resonance between the dehumidifier casing and the dehumidifier.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
