Description

Technical Field

[0001] This utility model relates to the field of air conditioner equipment technology, and in particular to an air conditioner anti-noise device and an air conditioner. Background Technology

[0002] Currently, when air conditioner indoor units are heating in low-temperature conditions, the main structure of the indoor unit is made of a plastic shell. In some locations, the gaps between the panel, bottom shell, and foam are too small, causing these components to compress and shift due to thermal expansion, resulting in abnormal noise. This phenomenon is particularly prominent at the air outlet of the indoor unit. Under the combined effect of shell compression caused by heat and airflow vibration, the abnormal noise at the air outlet is generally continuous. It only disappears after the unit has been running for a while and the parts have reached a certain temperature, allowing the plastic components to deform and heal. However, this process takes time, severely impacting the user experience and failing to meet user comfort requirements. Therefore, there is an urgent need for an air conditioner noise prevention device to solve the problem of abnormal noise caused by structural deformation at the air outlet of the indoor unit during heating mode.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] This utility model provides an air conditioner noise prevention device and an air conditioner, which aims to solve the problem of abnormal noise caused by heat deformation of the air outlet structure of the indoor unit of the air conditioner under the heating state.

[0033] To illustrate this solution more clearly, an example of the connection structure of an air conditioner casing in the prior art is provided. (Refer to...) Figure 1 The air conditioner shown in the figure has a bottom housing 10 and a front panel housing 20. After installation, there is an assembly gap 11 between the two housings. When the air conditioner is in auxiliary heating mode, since the housings are typically molded as a single piece of plastic, this assembly gap 11 gradually narrows as the housings heat up. This process generates friction and squeezing deformation, producing abnormal noise. Furthermore, after the assembly gap 11 is compressed, the airflow from the air conditioner causes the housings to vibrate and rub against each other. Because the bottom housing 10 and the front panel housing 20 have different structures, their vibration frequencies are different, also producing abnormal noise, affecting the user experience. Therefore, this air conditioner anti-noise device was designed.

[0034] Reference Figures 2 to 8The air conditioner noise prevention device of this utility model includes: a first air conditioner housing; a second air conditioner housing, assembled and connected to the first air conditioner housing, the second air conditioner housing having an air outlet 21 and a slide rail 22, the air outlet 21 being located near the first air conditioner housing and the slide rail 22 extending in a direction close to the first air conditioner housing; and a filler 30 slidably disposed on the slide rail 22; wherein, an assembly gap 11 is provided between the first air conditioner housing and the second air conditioner housing, and when the air conditioner is in heating mode, the filler 30 slides into the assembly gap 11.

[0035] The second air conditioner housing has an air outlet 21 and a slide rail 22. The air outlet 21 is located close to the first housing. A slide rail 22 is provided at the edge of the air outlet 21, extending along the direction close to the first air conditioner housing. Specifically, the slide rail 22 can be made of extruded plastic or metal and then connected to the second air conditioner housing by clips or bolts to provide good sliding performance and wear resistance. The slide rail 22 provides a sliding guide channel for the filler 30, ensuring that the filler 30 can slide smoothly along the direction of the air outlet 21. Furthermore, the filler 30 is a structural component with elastic or flexible properties, and can be made of materials such as elastic plastic or silicone. Its shape is designed to conform to the contour of the assembly gap 11 between the first and second air conditioner housings. Due to the thickness and elasticity of the filler 30, it can be adjusted to fit into or disengage from the assembly gap 11 during sliding.

[0036] Specifically, when the air conditioner is in heating mode, due to the low temperature of the indoor unit, the assembly gap 11 between the first and second air conditioner housing components is small, making them prone to relative movement and abnormal noise due to thermal expansion and contraction. To address this, the air conditioner's control system drives the filler 30 to slide along the slide rail 22, embedding it into the assembly gap 11 between the first and second air conditioner housing components. Specifically, when the air conditioner is in heating mode, each plastic housing component first expands and compresses the assembly gap 11, causing it to disappear, or, if the assembly gap 11 exists, the housing components come into contact. This process requires a certain amount of time, known as the initial expansion time. The initial expansion time has a mathematical relationship with the current ambient temperature and the air conditioner's heating temperature; this mathematical relationship was established through multiple actual experimental measurements. When in use, the air conditioner's control system predicts the length of the initial expansion time based on the above mathematical formula, and sends a signal to the drive device after the initial expansion time has elapsed. The drive device drives the slider to move along the slide rail 22, pushing the filler 30 into the assembly gap 11 or abutting against the housing. The elastic properties of the filler 30 and its cooperation with the slide rail 22 ensure that it is in close contact with the junction of the two housings, that is, the inner surface of the housings on both sides near the assembly gap 11, thereby maximizing the thermal expansion displacement limit of the housings on both sides of the assembly gap 11, thereby slowing down or eliminating the relative movement of parts caused by thermal expansion and contraction, and significantly reducing the occurrence of abnormal noise.

[0037] In addition, in the cooling state, in order to prevent condensate formed at the air vent from dripping out of the assembly gap 11, the control system will also move the filler 30 to insert into the assembly gap 11, thereby sealing the assembly gap 11 and preventing condensate from dripping down, thus ensuring that the condensate has enough time to be discharged from the casing so as not to affect the user's experience.

[0038] Compared with the prior art, this utility model provides a filler 30 that can slide into the assembly gap 11 between the two housing parts of the air conditioner when the air conditioner is heating, which prevents the two housing parts from directly contacting each other due to thermal expansion. This avoids the problem of friction noise caused by airflow vibration at the air outlet 21 after the two housing parts come into contact.

[0039] In one embodiment, reference is made to Figure 2 and Figure 3The first air conditioner housing component is the bottom housing 10, and the second air conditioner housing component is the air conditioner panel housing 20. The slide rail 22 is located on the inner side of the air conditioner panel housing 20. The first air conditioner housing component, the bottom housing 10, serves as the bottom structure of the air conditioner, supporting the entire internal component frame. The second air conditioner housing component, the air conditioner panel housing 20, is mainly responsible for covering the panel's appearance and guiding the air outlet 21. During assembly, the slide rail 22 is located on the inner side of the air conditioner panel housing 20, arranged parallel to the width direction of the air outlet 21, and matches the structural design of the panel housing. The function of the slide rail 22 is to serve as a guide channel for the filler 30, ensuring that the filler 30 can slide smoothly along a predetermined trajectory within the panel housing. By placing the slide rail 22 on the inner side of the panel housing, precise sliding control is facilitated during subsequent adjustments and maintenance, without affecting the aesthetic appearance of the panel.

[0040] In one embodiment, reference is made to Figure 5 and Figure 6The air conditioner noise prevention device also includes a motor 40, which is located on the inner side of the air conditioner panel housing 20 and close to the slide rail 22. The motor 40 drives the filler 30 to slide on the slide rail 22. A drive gear 41 is provided on the output shaft of the motor 40. The filler 30 includes a protrusion structure 31 and at least one driven toothed belt 33. The driven toothed belt 33 is connected to the protrusion structure 31. The protrusion structure 31 is positioned close to the assembly gap 11 and has a protrusion 32 in the direction of the assembly gap 11. The driven toothed belt 33 is slidably disposed in the slide rail 22. The drive gear 41 meshes with the driven toothed belt 33. When the protrusion structure slides to its limit position close to the assembly gap 11, the protrusion 32 is embedded in the assembly gap 11. The motor 40 is located on the inner side of the air conditioner panel housing 20 and close to the slide rail 22. The motor 40 is a miniature DC motor, characterized by its compact size and fast response. A drive gear 41 is mounted on its output shaft, which meshes with a driven toothed belt 33 via gear transmission. The motor 40 automatically starts and stops according to the air conditioner's operating status via a controller, driving the drive gear 41 to rotate, thereby causing the driven toothed belt 33 to slide along the slide rail 22. Because the filler 30 is made of a flexible material, possessing a certain degree of elasticity and flexibility, the driven toothed belt 33 is connected to both ends along the length of the air outlet 21. The driven toothed belt 33 slides along the slide rail 22, causing the protrusion structure 31 to move accordingly. When the motor 40 drives the gear to rotate, the driven toothed belt 33 slides along the slide rail 22, pushing the protrusion structure 31 towards or away from the assembly gap 11, adjusting to the changes in the assembly gap 11 to prevent abnormal noise. This structural design automates the adjustment process and ensures smooth sliding, avoiding vibration and noise caused by manual operation, effectively improving the comfort of using the air conditioner. Furthermore, the protrusion structure 31 includes a structure with a protrusion 32, positioned towards the assembly gap 11. The protrusion 32 is used to embed into the assembly gap 11 for fastening. During the sliding process of the protrusion structure 31, the protrusion 32 gradually approaches the assembly gap 11. As the sliding limit is reached, the protrusion 32 embeds into the assembly gap 11, ensuring that the assembly surface of the air outlet 21 is tightly fitted or separated, thereby controlling and protecting against abnormal noise. The advantages of this structure are its excellent embedding effect and reliability, ensuring the accuracy and stability of the adjustment position, while also facilitating automatic adjustment.

[0041] In one embodiment, reference is made to Figure 2 and Figure 3The air conditioner panel housing 20 has a first surface 24 and a second surface 25 connected on its inner side, with an included angle between them. The first surface 24 is located near the assembly gap 11. The slide rail 22 is disposed on the first surface 24 and the second surface 25. The driven toothed belt 33 is made of flexible material. Specifically, the connection between the first surface 24 and the second surface 25 is achieved through a curved surface to facilitate the guidance of the sliding component. The slide rail 22 is disposed on these two surfaces and arranged along the length of the air outlet 21 to ensure that the driven toothed belt 33 slides smoothly along a predetermined trajectory during adjustment. Because the driven toothed belt 33 is made of flexible material, it has a certain degree of elasticity, and the flexible toothed belt conforms to the first surface 24, the second surface 25, and the curved surface between them.

[0042] In one embodiment, reference is made to Figures 4 to 8 The air outlet 21 has a slide rail 22 at each end along its length, and the protrusion structure 31 extends along the length of the air outlet 21. A driven toothed belt 33 is connected to each end of the protrusion structure 31 along the length of the air outlet 21. The air conditioner anti-noise device of this utility model also includes a first limiting wall 221 and a second limiting wall 222 spaced apart. The slide rail 22 is formed by the first limiting wall 221 and the second limiting wall 222 clamped together. A slide rail 22 is provided at each end of the air outlet 21 along its length to guide the sliding of the protrusion structure 31. The protrusion structure 31 extends along the length of the air outlet 21, and a driven toothed belt 33 is connected to each end. Specifically, the driven toothed belt 33 is located at both ends of the length of the air outlet 21 to ensure the movement stability of the protrusion structure 31. Each slide rail 22 is formed by a first limiting wall 221 and a second limiting wall 222 sandwiched together. The first limiting wall 221 is close to the air outlet 21, and the second limiting wall 222 is away from the air outlet 21, forming a sliding channel with limiting on both sides. This structure ensures that the slider does not deviate from the trajectory during sliding, avoiding jamming or displacement, thereby ensuring the accuracy of adjustment and the smoothness of operation.

[0043] In one embodiment, reference is made to Figure 4 and Figure 5The first limiting walls 221 of the two slide rails 22 located at both ends of the air outlet 21 along its length are arranged close to each other, while the second limiting walls 222 are arranged far apart from each other. The second limiting walls 222 are also provided with mounting guide surfaces 223, which are located away from the air conditioning panel housing 20. These guide surfaces 223 guide the driven toothed belt 33 into the slide rails 22. Specifically, the guide surfaces 223 are located away from the air conditioning panel housing 20 and towards the direction of movement of the sliding component, ensuring that the driven toothed belt 33 accurately enters the slide rails 22 during assembly, avoiding installation misalignment or jamming. This structure simplifies the assembly process, improves the positioning accuracy of the sliding component, and ensures the reliability and stability of the adjustment device. Furthermore, the second limiting wall 222 has a recess on the side near the slide rail 22 that moves away from the slide rail 22, and the driven toothed belt 33 has a protrusion on the side near the second limiting wall 222. Due to the presence of the guide surface 223, it is easier to insert the protrusion on the driven toothed belt 33 into the recess on the second limiting wall 222 during assembly. The cooperation between the recess and the protrusion structure makes the operation of the driven toothed belt 33 in the slide rail 22 more stable, which greatly reduces the probability of misalignment and derailment of the driven toothed belt 33 and the slide rail 22 when the air conditioning anti-noise device is working, especially when the filler 30 slides.

[0044] In one embodiment, reference is made to Figure 2 and Figure 3 The air conditioner panel housing 20 has a guide slope 26 near the protrusion 32. When the protrusion structure slides to its limit position near the assembly gap 11, the protrusion 32 abuts against the guide slope 26. The guide slope 26 near the protrusion 32 of the air conditioner panel housing 20 near the assembly gap 11 guides the protrusion 32 to embed into the assembly gap 11. When the protrusion structure 31 slides along the slide rail 22 to its limit position, the protrusion 32 abuts against the guide slope 26. Specifically, the guide slope 26 is a surface inclined to the surface of the air conditioner panel housing 20 near the assembly gap 11, i.e., there is an included angle between them. The guide slope 26 is located on the inner side of the panel housing, cooperating with the movement path of the protrusion 32. When the protrusion 32 contacts the guide slope 26, it can effectively guide the protrusion structure 31 into the predetermined position, ensuring that the action of embedding or leaving the assembly gap 11 is smooth and accurate. This structure not only improves the reliability of adjustment, but also reduces possible offset or jamming during sliding, thereby improving the overall adjustment accuracy and mechanical life.

[0045] This utility model also provides an air conditioner including the air conditioner anti-noise device as described in the above embodiments. This air conditioner can effectively alleviate noise through the adjustable filler 30 in heating mode, and can also automatically adjust the gap of the air outlet 21 in cooling mode to prevent condensation formation, thereby improving the overall performance of the air conditioner and the user experience. Furthermore, because the air conditioner anti-noise device is easy to assemble, adjust, and maintain, this air conditioner has good practicality and promotional value.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
