These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0056] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0057] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0058] Unless otherwise stated, the term "multiple" means two or more.

[0059] As can be seen from the background technology, the volute is an important component of the air duct of an indoor ceiling-mounted air conditioner. Its main function is to guide the airflow and generate appropriate resistance in the air duct to achieve effective air distribution and noise reduction.

[0060] In practical applications, the volute and the bottom tray of the indoor unit are integrated into one piece. This design facilitates processing through injection molding and also helps to achieve a tight connection between the volute and the chassis, thereby improving the structural strength and stability of the entire unit.

[0061] In related technologies, a pad can be placed on the surface of the volute to reduce the noise blown by the cross-flow fan onto the volute. Since the volute is integrated with the air conditioning chassis, the pad on its surface will be soaked in the condensate collected by the air conditioning chassis and affected by the wind. The pad is at risk of corrosion and breakage, and the pad debris will fall from the air outlet into the room, causing adverse effects on the indoor environment.

[0062] However, since the volute and the air conditioner chassis are integrally injection molded parts, the volute cannot be disassembled separately. The entire indoor unit needs to be disassembled to repair or replace the gasket, which is complicated and has high maintenance costs.

[0063] To address the aforementioned problems, this application provides an indoor air conditioning unit and air conditioning equipment. The indoor air conditioning unit includes an air conditioning top shell for connection to an indoor mounting surface; an air conditioning chassis connected to the bottom of the top shell, with an air intake area; a volute located on the side of the chassis facing the top shell, close to the air intake area, with a first mounting component and a second mounting component; and an air intake grille located within the air intake area, with a first end detachably connected to the second mounting component and a second end detachably connected to the chassis. The volute is detachably connected to the chassis via the first mounting component, allowing for individual disassembly. Furthermore, the air intake grille, volute, and top shell are also detachably connected. Maintenance can be performed by sequentially disassembling the air intake grille and volute without disassembling the entire indoor unit, significantly reducing the complexity and cost of maintenance and component replacement.

[0064] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0065] Combination Figures 1 to 3 As shown, one embodiment of this application provides an air conditioner indoor unit, including an air conditioner top cover 100, an air conditioner chassis 200, a volute 300, and an air inlet grille 400. The air conditioner top cover 100 is used to connect to an indoor mounting surface; the air conditioner chassis 200 is connected to the bottom of the air conditioner top cover 100, and the air conditioner chassis 200 is provided with an air inlet area 201.

[0066] It should be noted that the air conditioner top cover 100 and the air conditioner chassis 200 can constitute the housing structure of the air conditioner indoor unit. The housing structure of the air conditioner usually has a bottom surface and a top surface that are arranged opposite each other, a front side and a rear side that are arranged opposite each other, and a left side and a right side that are arranged opposite each other.

[0067] Combination Figure 1 As shown, the bottom and top surfaces of the shell structure can be along... Figure 1 The Z-axis distribution is in the middle, and the shell structure is oriented towards Figure 1 The Z-axis side is the top surface of the shell structure, and the shell structure faces away from it. Figure 1 The Z-axis side is the bottom surface of the shell structure.

[0068] The front and rear sides of the shell structure can be along Figure 1 The X-axis distribution is in the middle, and the shell structure is oriented towards Figure 1 The side in the X direction is the front of the shell structure, and the shell structure faces away from it. Figure 1 The side in the X direction is the rear side of the shell structure.

[0069] The left and right sides of the shell structure can be along Figure 1 The Y-axis distribution is in the middle, and the shell structure is oriented towards Figure 1 One side in the Y direction can be the left side of the shell structure, and the shell structure is away from... Figure 1 One side in the Y direction can be the right side of the shell structure.

[0070] Taking a ceiling-mounted air conditioner as an example, the air conditioner's top casing 100 is typically used to connect to an indoor mounting surface. This indoor mounting surface can be the ceiling, in which case the top surface of the casing structure connects to the ceiling. Alternatively, the indoor mounting surface can also be a vertical wall, in which case the rear side of the casing structure connects to the wall.

[0071] The air conditioner chassis 200 is connected to the bottom of the air conditioner top shell 100. The air conditioner chassis 200 and the air conditioner top shell 100 can be configured to form a flow channel for airflow to enter and exit. The inlet of the flow channel is connected to the air intake area 201.

[0072] The air conditioner top cover 100 and the air conditioner chassis 200 are surrounded by an air outlet 600 on the front side of the shell structure. The air outlet 600 faces the indoor area, and the outlet of the air duct is connected to the air outlet 600.

[0073] In some embodiments, the air conditioner top cover 100 is provided with a volute portion 110.

[0074] The volute section 110 helps guide and control the airflow path, ensuring that air can effectively flow out of the indoor unit of the air conditioner. This design optimizes aerodynamic performance and improves the efficiency and performance of the air conditioner.

[0075] Part of the volute 110 corresponds to the air inlet area 201, forming an air inlet channel. A heat exchanger 800 is installed inside the air inlet channel. After air enters the air inlet channel from the air inlet area 201, it exchanges heat with the heat exchanger 800 and can be converted into cold air or hot air.

[0076] An air outlet channel 700 is formed between the volute 110 and the volute tongue 300. The air outlet channel 700 is connected to the air inlet channel, together forming a flow channel. The airflow after heat exchange in the heat exchanger 800 flows to the air outlet channel 700 and finally flows out from the air outlet 600.

[0077] In some embodiments, a cross-flow fan (not shown in the figure) is also provided in the flow channel. The cross-flow fan can drive the airflow from the air inlet area 201 into the flow channel and drive the airflow after heat exchange with the heat exchanger 800 to flow out from the air outlet 600, thereby achieving the regulation of the indoor temperature.

[0078] In some embodiments, the volute 300 is disposed on the side of the air conditioner chassis 200 facing the air conditioner top cover 100, and the volute 300 is close to the air intake area 201.

[0079] The volute 300's placement and positioning optimize airflow, reducing airflow resistance and improving air conditioning efficiency by guiding airflow. Simultaneously, the volute 300's proximity to the air inlet helps better control airflow direction, reducing turbulence and noise.

[0080] In some embodiments, the volute tongue 300 is provided with a first mounting member, which is detachably connected to the chassis.

[0081] The detachable connection allows the volute tongue 300 to be disassembled for cleaning, repair, or replacement without affecting other components. This design greatly simplifies the maintenance process and reduces maintenance costs.

[0082] In some embodiments, the volute 300 is provided with a second mounting member, the air intake grille 400 is disposed in the air intake area 201, and the first end of the air intake grille 400 is detachably connected to the second mounting member, and the second end of the air intake grille 400 is detachably connected to the air conditioner top cover 100.

[0083] The detachable design of the air intake grille 400 allows it to be easily removed for cleaning or replacement, ensuring unobstructed airflow and preventing the accumulation of dust and debris. Meanwhile, its connection to the volute 300 and the air conditioning top cover 100 ensures structural integrity and smooth airflow.

[0084] The detachable connection between the volute 300 and the air conditioner chassis 200, as well as the detachable connection between the air intake grille 400 and the volute 300 and the air conditioner top cover 100, forms a modular design. This design allows for independent disassembly and maintenance of each component, reducing the impact on the entire indoor air conditioning unit.

[0085] Specifically, the air conditioner indoor unit provided in this application embodiment allows for easy individual maintenance and replacement of the volute 300 and air inlet grille 400 without disassembling the entire indoor unit, significantly reducing the complexity and cost of maintaining and replacing parts.

[0086] Combination Figure 4 As shown, in some embodiments, the first mounting component is provided with a first connecting hole, and the air conditioner chassis 200 is provided with a first connecting post 210; the air conditioner indoor unit also includes a locking screw (not shown in the figure), which passes through the first connecting hole and is connected to the first connecting post 210.

[0087] The first connecting post 210 mates with the first connecting hole, providing a clear positioning and fixing point for the connection between the volute tongue 300 and the air conditioning chassis 200, thus providing a stable connection foundation.

[0088] The use of locking screws provides a holding force, ensuring a more secure and reliable connection between the volute 300 and the chassis. The use of locking screws also simplifies the disassembly and installation process, requiring only tightening or loosening of the screws.

[0089] In the specific connection, the locking screw passes through the first connecting hole, and the screw head of the locking screw abuts against the surface of the first mounting part. The first connecting post 210 is provided with a threaded hole, and the screw body of the locking screw is threadedly connected to the first connecting post 210 through the threaded hole. As the engagement length between the screw body and the first connecting post 210 increases, the locking screw can fasten the first mounting part and the first connecting post 210 together.

[0090] This connection method ensures that the connection between the volute 300 and the chassis relies not only on friction or simple snap-fit, but also on mechanical locking with screws. This connection method improves stability and durability, reducing the risk of loosening during vibration or long-term use.

[0091] In some embodiments, the first mounting component includes a first horizontal mounting portion 310, a first connecting hole is formed on the first horizontal mounting portion 310, and the first horizontal mounting portion 310 is disposed on the side of the air conditioner chassis 200 away from the air conditioner top cover 100.

[0092] Understandably, the horizontal setting of the first horizontal mounting section 310 facilitates the opening of the connection hole and the installation of the locking screw, which helps to ensure the stability of the connection and improve the accuracy and efficiency of the installation.

[0093] The first horizontal mounting part 310 is located on the side of the air conditioning chassis 200 away from the top cover, that is, the first horizontal mounting part 310 is located on the outside of the air conditioning chassis 200. During disassembly and assembly, the operator can more easily access the first horizontal mounting part 310 and the locking screw, reducing obstacles during disassembly, making the installation and disassembly of the volute tongue 300 more convenient, and the maintenance and replacement process faster and more efficient.

[0094] In some embodiments, the first mounting component further includes a first vertical mounting portion 320, the top end of which is connected to the volute tongue 300, and the bottom end of which is connected to one end of the first horizontal mounting portion 310; the bottom of the air conditioner chassis 200 is provided with a first abutting portion 220 extending away from the air conditioner top cover 100; the surface of the first horizontal mounting portion 310 facing the air conditioner chassis 200 abuts against the bottom surface of the first abutting portion 220.

[0095] Understandably, the first vertical mounting part 320 and the first horizontal mounting part 310 form an L-shaped support structure to facilitate a stable connection between the first horizontal mounting part 310 and the volute tongue 300.

[0096] The first abutment portion 220 provides a structure for support and positioning, allowing the first horizontal mounting portion 310 to make close contact with it. The first horizontal mounting portion 310 contacts the bottom surface of the abutment portion, providing an effective support point, increasing the stability and vibration resistance of the first mounting member, ensuring that the first mounting member can maintain a stable position during installation, and preventing displacement due to vibration or other external forces.

[0097] In some embodiments, the bottom of the air conditioning chassis 200 is provided with a second abutment portion 230, and the second abutment portion 230 and the first abutment portion 220 are arranged in parallel; the first horizontal mounting portion 310 abuts against the surface of the second abutment portion 230 toward the first abutment portion 220.

[0098] The first horizontal mounting part 310 abuts against the second abutting part 230, and the abutting surface between the first horizontal mounting part 310 and the second abutting part 230 is perpendicular to the abutting surface between the first horizontal mounting part 310 and the first abutting part 220. This can provide additional support and positioning functions, increase the support area of ​​the mounting part, and improve its vibration resistance and displacement resistance.

[0099] Specifically, by setting the first horizontal mounting part 310 to contact the two abutment parts, the connection between the first horizontal mounting part 310 and the air conditioning chassis 200 can be more stable.

[0100] Combination Figure 5 As shown, in some embodiments, both ends of the volute tongue 300 in the extension direction are provided with positioning protrusions 330; the air conditioner chassis 200 is provided with a baffle 240 extending toward the air conditioner top shell 100, the baffle 240 is provided with a positioning groove 241 corresponding to the positioning protrusion 330, and the positioning protrusion 330 is embedded in the positioning groove 241.

[0101] Understandably, the extension direction of the cochlear tongue 300 is... Figure 1 The Y-axis is parallel.

[0102] The positioning protrusion 330 provides a structure for positioning and fixing. The positioning groove 241 cooperates with the positioning protrusion 330 to provide a simple and effective positioning and fixing mechanism, ensuring that the volute tongue 300 can be quickly positioned during installation and achieve a stable installation by embedding into the groove.

[0103] The positioning protrusion 330 is embedded in the positioning groove 241. This embedded design ensures that the connection between the volute tongue 300 and the chassis does not rely solely on screws or other fasteners. Even after the locking screws are removed, the volute tongue 300 remains connected to the chassis, preventing it from falling off. This design improves the safety and reliability of installation, especially during maintenance or replacement.

[0104] For example, the positioning groove 241 can be along the front-rear direction of the housing structure (i.e., Figure 1 The positioning groove 241 extends in the X direction and is connected to the outside at one end facing the rear side of the housing structure.

[0105] When disassembling the volute tongue 300, the positioning protrusion 330 can slide along the extension direction of the positioning groove 241. When the positioning protrusion 330 slides to the end of the positioning groove 241 facing the rear side of the housing structure, the volute tongue 300 can be removed. When installing the volute tongue 300, the positioning protrusion 330 can be inserted into the positioning groove 241 from the end of the positioning groove 241 facing the rear side of the housing structure.

[0106] In some embodiments, the baffle 240 provided on the surface of the air conditioner chassis 200 can be configured to form a receiving area for collecting condensate generated during the operation of the indoor unit of the air conditioner, so as to prevent the condensate from dripping.

[0107] The containment area can be equipped with a drain outlet, which can be connected to the air conditioner's drain pipe to drain the condensate collected within the containment area.

[0108] Combination Figure 4 As shown, in some embodiments, the first end of the air inlet grille 400 is provided with a connecting strip 410, and the connecting strip 410 is provided with a second connecting hole; the second mounting part includes a second horizontal mounting part 340, which is reused to form the base plate of the volute tongue 300, and the second horizontal mounting part 340 is provided with a second connecting column 341. The air conditioner indoor unit also includes a locking screw, which passes through the second horizontal mounting part 340 and is connected to the second connecting column 341.

[0109] The connecting strip 410 provides a structure for fixing and connecting the air intake grille 400, so that the air intake grille 400 can be securely installed on the second mounting piece.

[0110] The second horizontal mounting section 340 also serves as the base plate of the volute tongue 300, simplifying the structure while providing sufficient structural strength and stability.

[0111] The second connecting post 341 cooperates with the second connecting hole to provide a simple and effective connection mechanism. Combined with the use of locking screws, the connection between the air intake grille 400 and the volute tongue 300 is achieved through mechanical locking, which improves the stability and durability of the connection, reduces the risk of loosening during vibration or long-term use, and also makes the disassembly and installation process easier, simply by tightening or loosening the screws.

[0112] In the specific connection, the locking screw passes through the second connecting hole, and the screw head of the locking screw abuts against the surface of the connecting strip 410. The second connecting post 341 may be provided with a threaded hole, and the screw body of the locking screw is threadedly connected to the second connecting post 341 through the threaded hole. As the engagement length between the screw body and the second connecting post 341 increases, the locking screw can fasten the connecting strip 410 and the second connecting post 341 together, thereby realizing the fixed connection between the first end of the air intake grille 400 and the second mounting part.

[0113] It should be noted that the second end of the air intake grille 400 can also be connected to the air conditioner top cover 100 by locking screws or by clips, as long as a stable connection and detachability between the air intake grille 400 and the air conditioner top cover 100 can be achieved. This application embodiment does not impose any restrictions on this.

[0114] In some embodiments, the second mounting member further includes a second vertical mounting portion 350, a connecting strip 410 abutting against the second horizontal mounting portion 340 on the surface of the volute tongue 300, and a connecting strip 410 abutting against the second vertical mounting portion 350 on the surface of the connecting strip 410 away from the air intake grille 400.

[0115] The connecting strip 410 abuts against the second horizontal mounting part 340 on the surface of the volute tongue 300, ensuring that the connecting strip 410 can maintain a stable position during installation.

[0116] The connecting strip 410 has an extension 411 on its surface away from the air inlet grille 400. The extension 411 is perpendicular to the connecting strip 410 and abuts against the second vertical mounting part 350.

[0117] The abutment surfaces between the connecting strip 410 and the second horizontal mounting portion 340 and between the extension portion 411 and the second vertical mounting portion 350 are perpendicular, which can provide additional support and positioning functions, and also increase the support area of ​​the connecting strip 410, thereby improving its vibration resistance and displacement resistance.

[0118] In some embodiments, a volute tongue liner 500 is also included, which covers the outside of the volute tongue 300, and at least a portion of the volute tongue liner 500 covers the surface of the second mounting member facing the air intake grille 400.

[0119] By adding a volute tongue gasket 500 to the outside of the volute tongue 300, noise generated by airflow can be effectively absorbed and blocked, thereby improving the quietness of the air conditioner. The volute tongue gasket 500, covering the outside of the volute tongue 300, also protects the volute tongue 300, reduces the direct impact and wear of airflow on it, extends its service life, and improves the overall performance of the air conditioner.

[0120] Specifically, the volute tongue pad 500 can be attached to the surface of the volute tongue 300.

[0121] Part of the volute tongue gasket 500 covers the surface of the second mounting member. After the second mounting member is connected to the first end of the air intake grille 400, in the vertical direction, the volute tongue gasket 500 is located between the second mounting member and the first end of the air intake grille 400.
