Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] In air conditioners, especially those with the compressor located in the indoor unit, the core components such as the compressor, condenser, and evaporator are housed inside the casing. For aesthetic purposes and airflow, a grille is typically installed at the front of the casing. This grille not only serves a decorative function but also protects the internal electrical components and allows airflow for heat exchange. The grille is usually directly fixed to the casing with screws or other fasteners. While this method is simple and straightforward, in practice, due to various factors (such as installation precision, material properties, and manufacturing tolerances), a certain gap usually remains between the grille and the casing. When the air conditioner is running, vibrations from the compressor and other components are transmitted to the grille, causing resonance or noise, thus affecting the user experience. Utility Model Content

[0003] The main purpose of this utility model is to propose an air conditioner that aims to solve the problems of vibration, resonance, and collision noise caused by the gap between the grille and the rear panel.

[0004] To achieve the above objectives, this utility model proposes an air conditioner comprising:

[0005] The casing has an air vent area;

[0006] Grille elements, installed in the air vent area; and

[0007] An elastic buffer is provided between the housing and the grille.

[0008] In one embodiment, the elastic buffer includes a first elastic buffer that is clamped between the edge of the air vent area and the edge of the grille.

[0009] In one embodiment, the first elastic buffer is disposed at the edge of the air vent area.

[0010] In one embodiment, the air vent area is located on the side of the housing, and the first elastic buffer is located at the lower edge of the air vent area.

[0011] In one embodiment, the first elastic buffer is provided in multiple portions at intervals along the lower edge of the air vent area.

[0012] In one embodiment, the lower edge of the air vent area is provided with a slot portion, the upper end of the air vent area is provided with a fastening portion, the lower end of the grille is provided with a plug-in portion corresponding to the slot portion, and the upper end of the grille is provided with a snap-fit ​​portion corresponding to the fastening portion.

[0013] In one embodiment, the air vent area includes a ventilation opening that penetrates the housing and a dummy air vent recessed relative to the outer surface of the housing. The elastic buffer includes a second elastic buffer, and the dummy air vent and the grille together clamp the second elastic buffer.

[0014] In one embodiment, the second elastic buffer is disposed on the grille and corresponds to the middle of the dummy air vent.

[0015] In one embodiment, the grid member is provided with limiting ribs around the second elastic buffer member.

[0016] In one embodiment, the elastic buffer is made of elastic sponge material.

[0017] In one embodiment, the elastic buffer is adhered to the housing or the grille.

[0018] In one embodiment, the air conditioner includes an indoor unit and an outdoor unit. The indoor unit includes the casing, the grille, and the elastic buffer. The air conditioner also includes a flexible refrigerant pipe. The indoor unit and the outdoor unit are connected through the flexible refrigerant pipe to form a refrigerant circuit, and refrigerant is pre-injected into the refrigerant circuit.

[0019] In one embodiment, the compressor of the air conditioner is located in the indoor unit of the air conditioner.

[0020] The technical solution of this utility model is to set an elastic buffer between the casing and the grille. The elastic buffer generates elastic force to support the grille, thereby reducing the contact between the air intake grille and the casing. Compared with the original grille, which directly contacts the casing through gaps caused by various factors, the grille contacts the elastic buffer to form an effective buffer system, thus improving the vibration and noise problems of the grille in related technologies.

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 scope of protection of the present utility model.

[0034] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text implies three parallel solutions. For example, "wind vent area and / or B" includes the wind vent area solution, solution B, or a solution that simultaneously satisfies both the wind vent area and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] In air conditioners, especially those with the compressor located in the indoor unit, the core components such as the compressor, condenser, and evaporator are housed inside the casing. For aesthetic purposes and to facilitate air circulation, a grille is usually installed at the front of the casing. This grille not only serves a decorative function but also protects the internal electrical components and allows air to pass through for heat exchange.

[0037] The grille is usually fixed directly to the housing with screws or other fasteners. Although this fixing method is simple and direct, it has some problems. When the air conditioner is running, the vibration generated by the compressor and other components is transmitted to the grille, causing the grille to resonate or make noise, which affects the user experience.

[0038] To address these issues, some existing technologies attempt to improve the rigidity and stability of the air intake grille and rear panel by strengthening their structural design, thereby reducing deformation and displacement caused by vibration and thus reducing collision noise. However, in practical applications, due to various factors (such as installation accuracy, material properties, manufacturing tolerances, etc.), there is usually still a certain gap between the grille and the housing. The size of this gap may vary depending on the design and manufacturing process, thus limiting its vibration damping and noise reduction effect.

[0039] Therefore, this utility model provides an air conditioner structure that can effectively reduce vibration and noise transmission, especially by improving the fixing and buffering method between the grille and the casing, so as to achieve stable installation of the grille and effective vibration and noise reduction.

[0040] The air conditioner can be an integrated air conditioner or a split air conditioner (including an indoor unit and an outdoor unit). In this solution, it is a split air conditioner with the compressor located in the indoor unit.

[0041] Please see Figures 1 to 4In one embodiment of this utility model, the air conditioner includes a housing 100, a grille 200, and an elastic buffer 300. The housing 100 houses core components such as a compressor, condenser, and evaporator. An air vent area 110 is provided on the outer surface of the housing 100. To address the noise generated by the movement of the grille 200 relative to the housing 100, an elastic buffer 300 is provided between the housing 100 and the grille 200. The housing 100 and the grille 200 abut against the elastic buffer 300. When there is no external force (such as vibration), the elastic buffer 300 fills the gap between the grille 200 and the housing 100 due to various factors (such as installation accuracy, material properties, manufacturing tolerances, etc.) due to its own elasticity, thus providing support. When the air conditioner is running, the grille 200 is tightly attached to the housing 100, reducing the possibility of movement of the grille 200 relative to the housing 100, thereby improving the noise generated by the collision of the grille 200.

[0042] In one embodiment, the elastic buffer 300 is disposed on the housing 100.

[0043] In one embodiment, the elastic buffer 300 is disposed on the grid member 200. The method of fixing the elastic buffer 300 is not limited, and it can be glued, screwed, snap-fitted, etc. The elastic buffer 300 can be made of sponge, rubber, silicone, spring damper, etc.

[0044] The technical solution of this utility model is to set an elastic buffer 300 between the housing 100 and the grille 200. The elastic buffer 300 generates elastic force to support the grille 200, thereby reducing the contact between the air intake grille 200 and the housing, thus forming an effective buffer system to solve the vibration and noise problems of the grille 200 in the prior art. Furthermore, by installing the compressor inside the air conditioner indoor unit, the weight of the air conditioner outdoor unit can be reduced, making the installation of the outdoor unit more flexible. The reduced weight of the outdoor unit makes the installation process simpler and lowers the technical requirements for installation workers.

[0045] Specifically, the elastic buffer 300 includes a first elastic buffer 310, which is clamped between the edge of the air vent region 110 and the edge of the grille 200. The first elastic buffer 310 is located at the edge of the air vent region 110. By clamping the first elastic buffer 310, the connection between the air vent region 110 and the grille 200 becomes more stable. This stable connection helps reduce loosening or displacement caused by vibration or external forces, thereby improving the stability of the entire system.

[0046] The air vent area 110 is located on the side of the housing 100, which is rectangular in shape. The air vent area 110 is situated on the rear panel between the upper and lower top covers. The first elastic buffer 310 is located at the lower edge of the air vent area 110. The first elastic buffer 310 fills the space between the grille 200 and the housing 100. When the grille 200 tends to fall under the influence of gravity and moves towards the lower edge of the air vent area 110, the first elastic buffer 310 can absorb and disperse this vibration energy, preventing the grille 200 from colliding with the housing 100, thereby reducing noise levels and providing a quieter operating environment.

[0047] The air vent region 110 includes a vent 120 penetrating the housing 100 and a dummy air vent 130 recessed relative to the outer surface of the housing 100; a second elastic member is disposed on the dummy air vent 130. In one embodiment, the air vent region 110 is rectangular, and is further divided into two rectangular areas, namely the vent 120 and the dummy air vent 130, with the vent 120 being larger than the dummy air vent 130; the vent 120 has an air inlet, while the dummy air vent 130 is a complete panel without an air inlet; the first elastic member provides stable support for the grille 200 on the dummy air vent 130. Because the elastic member has a certain elasticity, it can deform under pressure, thereby absorbing and dispersing the weight and vibration from the grille 200.

[0048] Furthermore, for secure installation, the grille 200 has an insertion portion 210 and a snap-fit ​​portion 220 on opposite sides, respectively. The housing 100 has a slot portion 111 corresponding to the insertion portion 210 and a fastening portion 112 corresponding to the snap-fit ​​portion 220. The grille 200 is inserted into the slot portion 111 via the insertion portion 210 and the slot portion 111, and then snapped into place on the housing 100 via the snap-fit ​​portion 220 and the fastening portion 112. A dummy air vent 130 is located adjacent to the slot portion 111. The combined design of the insertion portion 210 and the snap-fit ​​portion 220 provides a dual fixing mechanism, ensuring a secure connection between the grille 200 and the housing 100. The insertion portion 210 allows the grille 200 to be easily inserted into the slot portion 111, while the snap-fit ​​portion 220, through its cooperation with the fastening portion 112, securely fixes the grille 200 to the housing 100. This dual-fixation method not only improves the stability of the grille 200 installation but also helps reduce vibration and noise, thereby enhancing the overall performance of the air conditioning system. The plug-in and snap-fit ​​design makes the installation process of the grille 200 extremely simple. Installers simply align the plug-in part 210 with the slot part 111 and insert it, then engage the snap-fit ​​part 220 with the fastening part 112. This installation method requires no additional tools or complicated procedures, greatly improving installation efficiency. Similarly, since the connection between the grille 200 and the housing 100 is achieved through plug-in and snap-fit, the grille 200 can be easily removed when maintenance or replacement is required. This reduces maintenance costs and time.

[0049] In one embodiment, the first elastic member is disposed between the insertion portion 210 and the slot portion 111; in another embodiment, the first elastic member is disposed between the snap-fit ​​portion 220 and the fastening portion 112, and also between the snap-fit ​​portion 220 and the fastening portion 112. The second elastic member mainly provides support and cushioning for the dummy air vent 130, while the first elastic member provides additional cushioning for the connection between the insertion portion 210 and the slot portion 111. This dual-cushioning design makes the connection between the entire grille 200 and the housing 100 more stable, and at the same time can more effectively absorb and disperse vibrations, improving the vibration damping performance of the air conditioning system.

[0050] Specifically, the slot portion 111 is located relatively close to the bottom of the housing 100, and the first elastic member includes at least two, which are spaced apart from the slot portion 111 in the width direction of the housing 100.

[0051] In one embodiment, there are two first elastic members, and a slot portion 111 is disposed between the two first elastic members; in another embodiment, there are two slot portions 111, and the two first elastic members and the two slot portions 111 are arranged alternately in sequence.

[0052] Specifically, the first elastic element is set as an elastic sponge and is bonded to the housing 100.

[0053] Furthermore, the elastic buffer 300 includes a second elastic buffer 320, which is held together by the dummy air vent 130 and the grille 200. Since the second elastic buffer is located on the dummy air vent 130, rather than the vent 120, it does not obstruct airflow into or out of the indoor unit. This ensures the normal ventilation and heat dissipation functions of the air conditioning system. The second elastic buffer is located on the grille 200, allowing installers to simply place the grille 200 on the dummy air vent 130 and secure it, simplifying installation.

[0054] In one embodiment, the length of the second elastic member is similar to the length of the dummy air vent 130, that is, the lengths of the second elastic member and the dummy air vent 130 are approximately the same.

[0055] To save materials and reduce costs, in one embodiment, the second elastic member is rectangularly positioned in the center of the dummy air vent 130. By placing the second elastic member in the center of the dummy air vent 130, the needs for support and cushioning can be precisely met, while avoiding unnecessary material waste. Since the elastic member only needs to cover the critical part of the dummy air vent 130, the amount of material used can be significantly reduced. Although the length of the second elastic member is less than the length of the dummy air vent 130, it still provides stable support for the grille 200 because it extends to the edge of the dummy air vent 130 in the width direction. This ensures that the grille 200 can evenly distribute and absorb vibrations when subjected to pressure.

[0056] Specifically, the second elastic element is made of elastic sponge and is bonded to the grid element 200. This makes installation easier and the manufacturing of the second elastic element easier.

[0057] Specifically, the air vent area 110 is recessed into the surface of the housing 100, and the thickness of the second elastic element is greater than the depth of the recess in the air vent area 110. Because the thickness of the elastic element is greater than the depth of the recess, when the grille 200 is subjected to pressure, the elastic element can undergo greater deformation to absorb and disperse this pressure, thereby enhancing the support stability of the grille 200. The recessed air vent area 110 does not compromise the overall aesthetics of the indoor air conditioning unit; once the grille 200 is installed, the user can hardly see the elastic element and the air vent area 110.

[0058] Furthermore, the grille 200 is provided with limiting ribs 230 around the second elastic buffer 320. The limiting ribs 230 can limit the collapse deformation of the second elastic buffer 320 and maintain the supporting force of the second elastic buffer 320 on the dummy air vent 130 and the grille 200.

[0059] The second elastic element prevents the grille 200 from moving vertically (X-direction) relative to the surface of the housing 100, while the first elastic element helps reduce the direct transmission of vibration from the insertion part 210 to the slot part 111, i.e., movement parallel to the surface of the housing 100 (Y-direction). When the grille 200 is subjected to external force, the first elastic element can deform, thereby absorbing some vibration energy and reducing the impact of vibration on the housing 100 and internal components. The first elastic element is usually hidden between the insertion part 210 and the slot part 111, without compromising the overall aesthetics of the air conditioner indoor unit. Once the grille 200 is installed in place, the user can hardly see the presence of the first elastic element, thus maintaining the cleanliness and hygiene of the air conditioner indoor unit.

[0060] Furthermore, the indoor and outdoor units of the air conditioner are connected by flexible refrigerant pipes 400, forming a refrigerant circuit, which is pre-filled with refrigerant. The indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit are connected using flexible refrigerant pipes 400, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when users install the equipment themselves, they only need to fix the indoor and outdoor units separately, without needing to install refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual user installation.

[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
