Abstract
Description
Technical Field
[0001] This utility model relates to the field of water purifiers, and in particular to a soundproof door panel for a water purifier and a water purifier including the same. Background Technology
[0002] As people's living standards improve, commercial water purifiers are increasingly being installed in offices and large entertainment venues. These purifiers rely on water pumps for water purification, and these pumps generate significant noise. This noise is particularly noticeable during quiet lunch breaks, where even slight pump noise can be disruptive. Current technologies typically reduce noise leakage by improving the water purifier's sealing, but sound waves are penetrating, especially low-frequency sound waves. Simply relying on sealing can only reduce high-frequency noise leakage to a certain extent and is insufficient to effectively reduce the overall noise impact. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art in that it is difficult to effectively reduce noise by relying on sealing, and to provide a soundproof door panel for a water purifier and a water purifier including the same.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] This utility model provides a soundproof door panel for a water purifier, comprising a door panel body connected to the outer shell of the water purifier. The soundproof door panel further includes a sound insulation layer connected to and covering the inner wall and / or outer wall of the door panel body. The sound insulation layer includes a first cover plate and several support plates. The several support plates are inclinedly disposed between the first cover plate and the wall surface of the door panel body. The inclination directions of each pair of adjacent support plates are opposite, and several cavities are formed between the pairs of adjacent support plates. The projection of the several cavities in the direction perpendicular to the wall surface of the door panel body covers the inner wall of the door panel body.
[0006] In this design, as sound passes through the door panel, it causes the air in the sound insulation layer cavity to vibrate. The air vibration within the cavity rubs against the inner wall, converting most of the sound energy into heat energy, thus absorbing noise and reducing its propagation to the outside. Compared to sealing, which only reduces the path of sound waves along the air, sound waves are penetrating. By absorbing sound energy through the sound insulation layer, the propagation of noise can be effectively reduced.
[0007] Preferably, one end of each pair of adjacent support plates is connected to form an included angle so that the cross-section of the cavity is triangular.
[0008] In this scheme, multiple reflections increase the propagation time of sound waves in the cavity, thereby further improving the absorption effect.
[0009] Preferably, the included angle between any two adjacent support plates is 30 to 60 degrees.
[0010] In this design, a support plate angle of 30 to 60 degrees can achieve better sound absorption.
[0011] Preferably, a plurality of the support plates extend continuously from one end of the door panel body to the other end of the door panel body along the length or width direction of the door panel body.
[0012] In this design, continuous support plates form a rigid overall frame, distributing vibration energy evenly and preventing localized concentrated vibrations. Furthermore, compared to dividing the space into several small cavities, larger cavities are better at absorbing low-frequency noise.
[0013] Preferably, the sound insulation layer further includes a second cover plate, which is disposed between the support plate and the wall of the door panel body, and the first cover plate, the support plate and the second cover plate are integrally formed.
[0014] In this solution, by setting a second cover plate, the connection area between the support plate and the main body of the door panel can be increased, thereby improving the convenience and tightness of the connection between the sound insulation layer and the main body of the door panel.
[0015] Preferably, the soundproof door panel of the water purifier further includes an adhesive layer, and the soundproof layer is connected to the wall surface of the door panel body through the adhesive layer.
[0016] In this solution, the adhesive layer serves two purposes: firstly, it connects the sound insulation layer to the main body of the door panel; secondly, the adhesive layer itself has thickness and also provides sound insulation.
[0017] Preferably, the thickness of the sound insulation layer is 5-10 mm.
[0018] In this solution, a sound insulation layer thickness of 5-10mm can meet the sound insulation requirements while avoiding excessive overall weight of the water purifier's soundproof door panel.
[0019] Preferably, the sound insulation layer is made of ultrafine glass wool.
[0020] In this solution, the ultrafine glass wool is a porous fiber that has the effect of sound absorption and noise reduction.
[0021] This utility model also provides a water purifier, which includes the soundproof door panel of the water purifier as described above.
[0022] In this solution, as sound passes through the main body of the door panel, it causes the air in the sound insulation layer cavity to vibrate. The air vibration inside the cavity rubs against the inner wall of the cavity, thereby converting most of the sound energy into heat energy, achieving the effect of absorbing noise and reducing the transmission of noise to the outside.
[0023] Preferably, the water purifier includes an opening for installing a soundproof door panel, the soundproof door panel being sealed to the opening.
[0024] In this solution, the overall sealing of the water purifier can also isolate noise to a certain extent. Therefore, the sound insulation effect can be further improved by sealing on the basis of sound insulation and sound absorption.
[0025] The positive and progressive effects of this utility model are as follows:
[0026] This utility model discloses a soundproof door panel for a water purifier and a water purifier including the same. As sound passes through the main body of the door panel, the air in the cavity of the soundproof layer vibrates. The air vibration in the cavity rubs against the inner wall of the cavity, thereby converting most of the sound energy into heat energy, achieving the effect of absorbing noise and reducing the transmission of noise to the outside.

[0038] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment as an example.
[0039] like Figures 1-3As shown, this embodiment provides a soundproof door panel 100 for a water purifier, which includes a door panel body 1 connected to the outer shell of the water purifier. The soundproof door panel 100 also includes a sound insulation layer 2, which is connected to and covers the inner wall of the door panel body 1, and can also be connected to the outer wall of the door panel body 1. Preferably, the sound insulation layer 2 is provided on both the inner and outer walls. The sound insulation layer 2 includes a first cover plate 21 and a plurality of support plates 22. The plurality of support plates 22 are inclinedly disposed between the first cover plate 21 and the wall surface of the door panel body 1. The inclination directions of each pair of adjacent support plates 22 are opposite, and a plurality of cavities 23 are formed between the pairs of adjacent support plates 22. The projection of the plurality of cavities 23 in the direction perpendicular to the wall surface of the door panel body 1 covers the inner wall of the door panel body 1.
[0040] Thus, as sound passes through the main body 1 of the door panel, it causes the air in the cavity 23 of the sound insulation layer 2 to vibrate. The air vibration inside the cavity 23 rubs against the inner wall of the cavity 23, thereby converting most of the sound energy into heat energy, achieving the effect of absorbing noise and reducing the propagation of noise to the outside. Compared with sealing, sealing only reduces the path of sound waves along the air, but sound waves have penetrating power. By absorbing sound energy through the sound insulation layer 2, the propagation of noise can be effectively reduced.
[0041] In this embodiment, each pair of adjacent support plates 22 can be spaced apart and not connected, so that the cross-section of the cavity 23 in the direction perpendicular to the door panel body 1 is trapezoidal. Alternatively, one end of each pair of adjacent support plates 22 can be connected to form an included angle, so that the cross-section of the cavity 23 in the direction perpendicular to the door panel body 1 is triangular. Preferably, as shown... Figure 3 As shown, one end of each pair of adjacent support plates 22 is connected to form an angle so that the cross-section of the cavity 23 is triangular. Compared with the conventional honeycomb cavity 23 that is parallel to the direction of the door panel body 1 and has a regular hexagonal shape, the cavity 23 with a triangular vertical cross-section can make its inner wall surface form a certain angle with the sound wave, which is conducive to multiple reflections, increasing the propagation time of the sound wave in the cavity 23 and further improving the absorption effect.
[0042] When two adjacent support plates 22 form an angle, the angle is preferably between 30 and 60 degrees. An angle of 30 to 60 degrees between the support plates 22 can achieve better sound absorption.
[0043] Specifically, the support plates 22 can be arranged in multiple rows, resulting in a smaller cavity 23 that can absorb high-frequency noise. Preferably, the support plates 22 extend continuously from one end of the door panel body 1 to the other end along the length or width direction of the door panel body 1. This creates a larger cavity 23, which is beneficial for absorbing low-frequency noise.
[0044] In this way, the continuous support plates 22 form an integral rigid frame, and the vibration energy is evenly distributed, avoiding localized concentrated vibration. At the same time, compared with being divided into several small cavities 23, the larger cavity 23 is conducive to absorbing low-frequency noise. Since most of the noise generated by the water pump of the water purifier is low-frequency noise, it can effectively reduce the noise propagation of the water purifier.
[0045] Specifically, such as Figure 3 As shown, the sound insulation layer 2 also includes a second cover plate 24, which is disposed between the support plate 22 and the wall surface of the door panel body 1. The first cover plate 21, the support plate 22 and the second cover plate 24 are integrally formed.
[0046] Thus, by setting the second cover plate 24, the connection area between the support plate 22 and the door panel body 1 can be increased, thereby improving the convenience and tightness of the connection between the sound insulation layer 2 and the door panel body 1.
[0047] In this embodiment, the first cover plate 21, the support plate 22, and the second cover plate 24 are integrally formed, so that the second cover plate 24 is the connection surface between the sound insulation layer 2 and the door panel body 1. This can avoid the formation of discontinuous connection surfaces between several support plates 22 and the door panel body 1, which would reduce the firmness and convenience of the connection.
[0048] Specifically, the soundproof door panel 100 of the water purifier also includes an adhesive layer, and the soundproof layer 2 is connected to the wall of the door panel body 1 through the adhesive layer.
[0049] In this way, the adhesive layer can connect the sound insulation layer 2 to the door panel body 1, and the adhesive layer itself also has thickness, which can also play a sound insulation role.
[0050] In this embodiment, the thickness of the sound insulation layer 2 is 5-10mm. A thickness of 5-10mm for the sound insulation layer 2 can meet the sound insulation requirements while avoiding excessive overall weight of the water purifier sound insulation door panel 100.
[0051] Furthermore, the sound insulation layer 2 is made of ultrafine glass wool. Ultrafine glass wool is a porous fiber that has the effect of sound absorption and noise reduction.
[0052] This embodiment also provides a water purifier, which includes the soundproof door panel 100 of the water purifier as described above.
[0053] In this way, as the sound passes through the main body 1 of the door panel, it will cause the air in the cavity 23 of the sound insulation layer 2 to vibrate. The air vibration in the cavity 23 rubs against the inner wall of the cavity 23, thereby converting most of the sound energy into heat energy, achieving the effect of absorbing noise and reducing the transmission of noise to the outside.
[0054] Specifically, the water purifier includes an opening for installing a soundproof door panel 100, which is sealed to the opening.
[0055] In this way, the overall sealing of the water purifier can also isolate noise to a certain extent. Therefore, the sound insulation effect can be further improved by sealing on the basis of sound insulation and sound absorption.
[0056] In this embodiment, the sealing connection can be achieved by setting a sealing ring between the soundproof door panel 100 of the water purifier and the opening, or by pasting a sealing strip.
[0057] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
