Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically providing an indoor air conditioning unit and an air conditioner. Background Technology

[0002] In the air conditioning industry, product compactness and portability are crucial for improving user experience, reducing transportation costs, and expanding installation scenarios. However, current air conditioner structural designs have certain limitations.

[0003] Traditional air conditioners typically have their electrical enclosure located on the right side of the frame. While this layout meets the installation requirements of electrical components to some extent, it also presents significant problems. Because the electrical enclosure occupies space, the overall size of the frame is forced to increase, resulting in a substantial increase in the length of the entire unit. This increased length not only makes the air conditioner appear bulky and occupies more indoor space, affecting the aesthetics and harmony of the installation environment, but also causes considerable inconvenience to operators during actual handling and installation. It increases the difficulty of moving and installation time, and may even prevent successful installation in confined spaces.

[0004] Furthermore, excessively large size and weight increase transportation costs and reduce the product's market competitiveness. At the same time, with consumers increasingly demanding smaller and lighter home appliances, the traditional structural design of air conditioners is no longer sufficient to meet market needs.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0033] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the following embodiments are described in conjunction with an air conditioner indoor unit, the air conditioner indoor unit provided by the present invention is also applicable to other products that need to solve the problem of excessive length and weight of the entire unit due to improper placement of the electrical enclosure, making it difficult to meet the requirements for miniaturization and lightweighting.

[0034] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Based on the background art, this invention addresses the problem that existing air conditioners are too long and heavy due to improper placement of the electrical enclosure, making it difficult to meet the requirements for miniaturization and lightweight design. The present invention provides an indoor air conditioner unit that effectively solves the problem of existing air conditioners being too long and heavy due to improper placement of the electrical enclosure, thus failing to meet the requirements for miniaturization and lightweight design. This is achieved by fixing the electrical enclosure to the evaporator and positioning it between the two ends of the evaporator along its length.

[0036] like Figures 1 to 3 As shown, this utility model provides an indoor air conditioning unit, including a frame 1 and a cover 2 covering the outside of the frame 1. An evaporator 3 and an electrical box 4 are arranged inside the cover 2. The evaporator 3 is fixed on the frame 1, and the electrical box 4 is fixed on the evaporator 3 and located between the two ends of the evaporator 3 along the length direction of the evaporator 3.

[0037] The indoor air conditioner unit provided by this utility model mainly consists of a frame 1 and a cover 2. The cover 2 is the part that wraps around the outside of the frame 1, serving to protect the internal components and form the overall appearance.

[0038] In existing air conditioner designs, the electrical box 4 is improperly positioned, such as being placed at one end of the evaporator 3, resulting in an excessively large indoor unit in length. This invention employs a stacked layout, placing the electrical box 4 along the length of the evaporator 3 between the two ends. This reduces additional space occupation, making the overall structure of the indoor unit more compact. This allows for more functions to be implemented within a limited space or for the indoor unit's volume to be reduced, effectively controlling the length of the indoor unit and better meeting the requirements of miniaturization.

[0039] Furthermore, the electrical box 4 is fixed to the evaporator 3, which in turn is fixed to the frame 1, forming a relatively stable structural system. This multi-layered fixing method helps improve the stability of the entire indoor unit structure, reduces the loosening or displacement of components due to vibration or other reasons during operation, thereby reducing the probability of malfunctions and extending the service life of the indoor unit.

[0040] Preferably, such as Figure 2 and Figure 3 As shown, the electrical box 4 includes a box body 41 and a bracket 42. The box body 41 is mounted on the bracket 42, and the bracket 42 is mounted on the evaporator 3.

[0041] Since the electrical box 4 is connected to the evaporator 3 through the bracket 42, the shape, size and installation method of the bracket 42 can be flexibly designed when facing evaporators 3 of different specifications, sizes or shapes, so that the electrical box 4 can be adapted to various types of evaporators 3, which improves the universality and interchangeability of air conditioner indoor unit parts and reduces mold cost and R&D cost in the production process.

[0042] As an intermediate connector, bracket 42 can evenly distribute the weight and force of electrical box 4 onto evaporator 3, avoiding the problem of local stress concentration caused by electrical box 4 being directly fixed to a certain point on evaporator 3, reducing the possibility of deformation or damage to evaporator 3 due to uneven force, and improving the stability and reliability of the entire structure.

[0043] Furthermore, the design of the bracket 42 allows for a certain space between the electrical box 4 and the evaporator 3, which facilitates air circulation. Air can then circulate within this space, better dissipating the heat generated by the electrical box 4 during operation, improving heat dissipation efficiency, and preventing overheating of the electrical box 4 from affecting the performance and lifespan of electronic components.

[0044] Preferably, such as Figure 4 and Figure 5As shown, a positioning post 411 is provided on the first side of the housing 41, and a mounting ear 412 is provided on the second side of the housing 41. A positioning hole 421 adapted to the positioning post 411 is provided on the bracket 42. The housing 41 is positioned by inserting the positioning post 411 into the positioning hole 421, and is fixedly connected to the bracket 42 by the first fastener (not shown in the figure) passing through the mounting ear 412.

[0045] The design of the positioning pin 411 and the positioning hole 421 provides a precise positioning reference for the installation of the housing 41 on the bracket 42. During installation, the operator only needs to accurately insert the positioning pin 411 into the positioning hole 421 to quickly and accurately determine the installation position of the housing 41, avoiding installation position deviations caused by manual visual inspection or estimation, and greatly improving installation accuracy.

[0046] Furthermore, initial positioning is achieved by inserting the positioning pin 411 into the positioning hole 421, and then the first fastener is used to pass through the mounting ear 412 and fix it to the bracket 42, forming a double fixing structure. This double fixing method is more stable than the single fixing method, and can effectively prevent the enclosure 41 from loosening or shifting due to vibration, shaking or other reasons during use, ensuring the reliability and stability of the connection between the electrical box 4 and the bracket 42.

[0047] In the actual installation process, the positioning pin 411 of the box 41 is first inserted into the positioning hole 421 on the bracket 42 to achieve the initial positioning of the box 41 on the bracket 42 and ensure the accuracy of the installation position of the box 41; then, the first fastener (such as screw, bolt, etc.) is passed through the hole on the mounting ear 412 and fixedly connected to the bracket 42, so that the box 41 is firmly installed on the bracket 42.

[0048] Furthermore, when the electrical box 4 needs repair, replacement, or upgrade, simply remove the first fastener. Then, due to the certain clearance between the positioning pin 411 and the positioning hole 421, the box 41 can be easily removed from the bracket 42. This design makes the maintenance and disassembly process more convenient and quick, reducing maintenance time and workload.

[0049] Preferably, a second fastener (not shown in the figure) is provided on the second side of the housing 41, and the housing 41 is also fixedly connected to the bracket 42 by the second fastener.

[0050] When connected by a single fastener, the force at the connection point is mainly concentrated on that fastener. However, by adding a second fastener (such as a screw or bolt), a multi-point fixed connection is formed between the housing 41 and the bracket 42, which can distribute the various forces borne by the housing 41 (such as its own weight and the force generated by vibration during operation) to more fixed points. This multi-point fixing method greatly enhances the strength of the connection between the housing 41 and the bracket 42, effectively preventing the housing 41 from loosening or falling off during use, and ensuring the stability of the electrical box 4 during the operation of the air conditioner indoor unit.

[0051] Preferably, such as Figure 2 and Figure 3 As shown, the evaporator 3 includes fins 31 and a first tube sheet 32 ​​and a second tube sheet 33 respectively disposed on both sides of the fins 31 along the length direction of the fins 31. The first tube sheet 32 ​​and the second tube sheet 33 are both fixed on the frame 1, and the two ends of the bracket 42 are connected to the first tube sheet 32 ​​and the second tube sheet 33 respectively.

[0052] The first tube sheet 32 ​​and the second tube sheet 33 are fixed to the frame 1, providing two stable support points for the evaporator 3. The bracket 42 connects to these two tube sheets at both ends, effectively creating a connection structure for the electrical box 4 based on the stable support system of the evaporator 3. This multi-point connection method makes the connection between the electrical box 4, the evaporator 3, and the frame 1 more robust, effectively resisting vibrations and shaking generated during the operation of the indoor unit, reducing component loosening, displacement, or even damage caused by vibration, and improving the stability and reliability of the entire indoor unit structure.

[0053] Furthermore, by connecting bracket 42 to the first tube sheet 32 ​​and the second tube sheet 33 of the evaporator 3, the space on both sides of the evaporator 3 is fully utilized, allowing the electrical box 4 to be compactly installed near the evaporator 3 without occupying excessive space inside the indoor unit. This compact layout helps reduce the overall size of the indoor unit, making it more adaptable to different installation environments.

[0054] Preferably, the first end of the bracket 42 is fixedly connected to the first tube sheet 32 ​​by a third fastener (not shown in the figure), and the second end of the bracket 42 is fixedly connected to the second tube sheet 33 by a fourth fastener (not shown in the figure).

[0055] The third and fourth fasteners provide strong mechanical connection force, enabling the bracket 42 to be firmly fixed to the first tube sheet 32 ​​and the second tube sheet 33. Compared with some non-fastener connection methods (such as snap-fit ​​connections, adhesives, etc.), fastener connections have higher strength and reliability, and can withstand greater external forces, such as vibrations during the operation of the indoor air conditioning unit and collisions during transportation, effectively preventing the bracket 42 from loosening or separating from the tube sheet, and ensuring that the electrical box 4 is always in a stable position.

[0056] During the operation of the indoor unit of the air conditioner, the electrical box 4 is subjected to various dynamic and static forces. Through the multi-point connection of the third and fourth fasteners, these forces can be evenly distributed onto the first tube sheet 32 ​​and the second tube sheet 33, avoiding localized stress concentration. For example, when the electrical box 4 is subjected to vertical vibration, the third and fourth fasteners will share the force, making the stress on the tube sheet and support 42 more balanced, reducing problems such as fastener damage or tube sheet deformation caused by excessive stress, and further enhancing the stability of the connection.

[0057] For example, the third and fourth fasteners in this invention are screws or bolts.

[0058] Preferably, such as Figure 4 As shown, the first end of the bracket 42 is provided with a first flange 422 that bends toward the first tube plate 32, and the first flange 422 is engaged with the first tube plate 32.

[0059] The engagement between the first flange 422 and the first tube sheet 32 ​​forms a mechanical interlocking structure. When the first flange 422 is engaged in the corresponding slot or position of the first tube sheet 32, the two generate constraint forces in multiple directions. This ensures that the bracket 42 and the first tube sheet 32 ​​are tightly connected, greatly improving the stability of the connection and effectively preventing loosening caused by vibration or external impact.

[0060] Preferably, the second end of the bracket 42 is provided with a second flange (not shown in the figure) that bends toward the second tube sheet 33, and the second flange is engaged with the second tube sheet 33.

[0061] The first flange 422 engages with the first tube sheet 32, and the second flange engages with the second tube sheet 33, effectively fixing the bracket 42 from both ends simultaneously, forming a stable two-way support. During the operation of the indoor unit of the air conditioner, regardless of the direction of the force applied to the electrical box 4, such as horizontal pushing or pulling forces or vertical vibration and impact forces, this two-way engagement structure can effectively resist and prevent the bracket 42 from shaking, shifting, or falling off, greatly improving the stability of the entire connection structure and providing reliable support for the electrical box 4.

[0062] Furthermore, since both ends of the bracket 42 use a snap-fit ​​connection, the installation and disassembly procedures remain consistent. During installation, simply align the flanges at both ends of the bracket 42 with the snap-fit ​​positions on the first tube sheet 32 ​​and the second tube sheet 33, respectively, and apply appropriate pressure to snap both flanges into place. Then, use the third fastener to fix the first end of the bracket 42 to the first tube sheet 32 ​​and the fourth fastener to fix the second end of the bracket 42 to the second tube sheet 33 to complete the installation.

[0063] Preferably, the first tube sheet 32 ​​is a plastic tube sheet or a metal tube sheet, and the second tube sheet 33 is a plastic tube sheet or a metal tube sheet.

[0064] Plastic is a relatively inexpensive material, with lower raw material procurement costs compared to metal. Using plastic tubing in the mass production of air conditioner indoor units can effectively reduce manufacturing costs and enhance the product's market competitiveness. Metal, on the other hand, possesses high strength and rigidity, enabling it to withstand greater external forces. During the operation of the air conditioner indoor unit, the electrical box 4 and bracket 42 exert certain forces on the first tubing 32. The metal tubing ensures that no significant deformation or damage occurs under these forces, providing stable support for the electrical box 4 and guaranteeing the normal operation of the equipment.

[0065] For example, the first tube sheet 32 ​​in this invention is made of plastic, and the second tube sheet 33 is made of metal, thereby achieving a balance between strength and cost control. Of course, in other embodiments, both the first tube sheet 32 ​​and the second tube sheet 33 can be made of plastic or both can be made of metal. This invention does not limit the specific materials of the first tube sheet 32 ​​and the second tube sheet 33.

[0066] Preferably, the bracket 42 is provided with reinforcing ribs (not shown in the figure), which extend along the length of the bracket 42.

[0067] The reinforcing ribs and the main body of the support 42 form an organic whole, strengthening the connection and collaborative working ability between the various parts of the support 42. When subjected to external forces, the reinforcing ribs can transfer and coordinate the forces between the various parts, allowing the support 42 to bear the external forces as a whole, rather than each part bearing the force independently. This overall synergy improves the resistance of the support 42 to external forces and reduces structural failure caused by excessive local stress.

[0068] In addition, this utility model provides an air conditioner, which includes the above-mentioned indoor air conditioner unit.

[0069] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
