[0031] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. For example, although the following embodiments of the present application are described in combination with the air duct machine, this is not intended to limit the protection scope of the present application, and the present application can also be applied to other devices without deviating from the principles of the present application.

[0032] It should be noted that in the description of the present application, the terms indicating the direction or positional relationship of the terms "middle", "upper", "lower", "vertical", "inner", "outer" and the like are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0033] In the present application, "a plurality of" means two or more.

[0034] In addition, it should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected. It can be mechanically connected, or electrically connected. It can be directly connected, or indirectly connected through an intermediate medium. It can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] The present application provides a shell assembly and an air conditioner, which facilitates the installation of electrical components.

[0036] In combination Figure 1 and Figure 4 As shown in the drawings, the air duct machine provided by the present application comprises a case 100 and an electrical box cover 200.

[0037] The case 100 comprises a bottom plate 101 and a first side plate 102 arranged at one end of the bottom plate 101, and part of the wall of the first side plate 102 is recessed inwardly to form an electrical installation slot 103.

[0038] The electrical box cover 200 is detachably arranged at the opening of the electrical installation slot 103, and can close or open the electrical installation slot 103. When the electrical box cover 200 is installed at the opening of the electrical installation slot 103, the electrical box cover 200 can close the electrical installation slot 103; when the electrical box cover 200 is detached from the opening of the electrical installation slot 103, the electrical box cover 200 can open the electrical installation slot 103.

[0039] In combination Figure 1 , Figure 3 and Figure 5 As shown in the drawings, the electrical box cover 200 comprises a raised portion 201 corresponding to the electrical installation slot 103, and the raised portion 201 protrudes towards the side away from the electrical installation slot 103 to form a containing groove 202.

[0040] When adopting the above technical solution, the electrical enclosure of the duct air conditioner provided in this application is integrated with the first side panel 102 of the enclosure. Specifically, a portion of the wall of the first side panel 102 is recessed inward to form an electrical mounting groove 103, which is used to accommodate the electrical components of the duct air conditioner. By constructing the electrical mounting groove 103 on the first side panel 102, this application replaces the separately installed electrical enclosure, reducing the number of screws required for enclosure installation and avoiding the cumbersome steps of separately installing the enclosure. This simplifies the assembly process and improves production efficiency.

[0041] The electrical enclosure cover 200 and the electrical mounting slot 103 define the installation space for electrical components. By making the raised portion 201 of the electrical enclosure cover 200 protrude towards the side away from the electrical mounting slot 103 to form a receiving slot 202, the installation space for electrical components can be expanded. The receiving slot 202 provides additional installation area for electrical components (such as cables, control modules, etc.), significantly increasing the effective space for electrical component installation. For example, electrical components that were originally limited by the internal dimensions of the electrical mounting slot 103 can be flexibly arranged using the extended space of the receiving slot 202, thereby supporting the installation of more or larger electrical components. In addition, by providing the raised portion 201, some structures that originally needed to be embedded in the electrical mounting slot 103 can be transferred to the outside, allowing the wall thickness of the electrical mounting slot 103 to be reduced, reducing its occupation of the internal space of the chassis 100. This facilitates a more compact internal layout of the chassis 100 and frees up more space for other core components (such as heat exchangers, fans, etc.), improving the integration and functionality of the overall design.

[0042] The electrical box cover 200 and the electrical mounting groove 103 enclose and define the installation space for electrical components. This installation space can also be called the electrical mounting cavity. The space of the electrical mounting cavity is composed of two parts: the electrical mounting groove 103 and the receiving groove 202.

[0043] In some embodiments, combined with Figure 6 and Figure 7 As shown, the electrical mounting groove 103 is manufactured on the first side plate 102 by deep drawing or bending process. Figure 6 The electrical mounting slot 103 is manufactured using a bending process. Figure 7 The electrical mounting slot 103 is manufactured using a deep drawing process. By using deep drawing or bending processes, the electrical mounting slot 103 is directly manufactured on the first side plate 102, eliminating the need to manufacture separate electrical enclosure components, reducing the number of molds and production steps, and significantly lowering manufacturing costs.

[0044] Deep drawing is a sheet metal forming process that uses a punch and die to stretch a flat metal blank into a hollow part with a large depth. The core is to make the material plastic deformation by drawing force to form the required groove or cavity. Bending is a processing method that applies force to metal sheets by a press or bending machine to make plastic bending at a specific location.

[0045] For the cabinet 100, which constitutes the main body part of the ducted air conditioner, it can provide the space required for installing various devices and provide certain support and fixing functions. The cabinet 100 includes a bottom plate 101 and a first side plate 102.

[0046] In some embodiments, the first side plate 102 is detachably connected to the bottom plate 101. The first side plate 102 is detachably connected to the bottom plate 101, and the electrical components can be pre-installed in the electrical component mounting groove 103 of the first side plate 102, without the need to assemble electrical components in the final assembly stage as in the related art, and when the electrical components are pre-installed, the first side plate 102 can be reversed with the electrical component mounting groove 103 facing upwards, and the electrical components can be installed into the electrical component mounting groove 103 from above, which is more convenient and helps to improve assembly efficiency.

[0047] In some embodiments, in combination Figure 2 As shown, the cabinet 100 further includes a second side plate 104, and the second side plate 104 and the first side plate 102 are located at opposite ends of the bottom plate 101. Among them, the bottom plate 101 and the second side plate 104 are integrally formed.

[0048] In this embodiment, the bottom plate 101 and the second side plate 104 are integrated into one whole component by the method of integral molding, and the first side plate 102 and the electrical component mounting groove 103 are integrated into one whole component by the method of integral molding, which is formed by a set of molds at one time, not only greatly reducing the number of screws used and simplifying the assembly process, but also significantly improving the production efficiency of the components and the whole machine. At the same time, the integral molding structure enhances the overall strength, avoids the loosening or deformation problems that may occur in traditional split design, and further improves the reliability and service life of the ducted air conditioner. In addition, the electrical components can be pre-installed in the electrical component mounting groove 103, and then the first side plate 102 is installed on the bottom plate 101, without the need to assemble electrical components in the final assembly stage as in the related art, and when the electrical components are pre-installed, the first side plate can be reversed with the electrical component mounting groove facing upwards, and the electrical components can be installed into the electrical component mounting groove from above, which is more convenient and helps to improve assembly efficiency.

[0049] Among them, integral molding is a manufacturing process, which means that structures that originally require multiple independent components to be assembled are processed into one whole at one time through molds and molding techniques (such as injection molding). This technology realizes the seamless integration of components by eliminating the connection links (such as screws, welding, gluing, etc.) in traditional assembly.

[0050] In some embodiments, the fixing side of the protrusion 201 is provided with a fixing edge 203, and the fixing edge 203 is used for fixedly connecting with the first side plate 102. Figure 5 As shown in FIGS. 1, 2, and 3, the cabinet further includes a third side plate 105 which is perpendicular to the first side plate 102, and the third side plate 105 is integrally formed with the first side plate 102, and the third side plate 105 partially or entirely covers one side of the cabinet. In this way, components can be integrated, and the number of screws can be further reduced.

[0051] In some embodiments, the distance between the bottom of the accommodating groove 202 and the bottom of the electrical appliance mounting groove 103 is greater than or equal to 60 mm. In this way, sufficient electrical appliance mounting cavity space can be reserved, the effective space for electrical appliance mounting can be ensured, and more or larger electrical appliance elements can be supported.

[0052] In some embodiments, the fixing side of the protrusion 201 is provided with a fixing edge 203, and the fixing edge 203 is used for fixedly connecting with the first side plate 102. Figure 4 Figure 5 Figure 6 As shown in FIGS. 1, 2, and 3, the fixing side of the protrusion 201 is provided with a fixing edge 203, and the fixing edge 203 is used for fixedly connecting with the first side plate 102.

[0053] In some embodiments, the fixing edge 203 of the electrical appliance cabinet cover 200 is detachably connected with the cabinet 100 through bolts or buckles. Through the detachable connection mode of the bolts or buckles, the assembly process of the fixing edge 203 and the cabinet 100 does not require complex tools or additional steps, and an operator can quickly complete the installation or disassembly. For example, the buckle design can realize the assembly effect of “one press and one fit”, and the bolt connection simplifies the positioning through the standardized interface, significantly reduces the time and labor cost required by the traditional welding or riveting process, and thus improves the overall production efficiency.

[0054] For example, the fixing edge 203 of the electrical appliance cabinet cover 200 is provided with a plurality of first connecting holes, the first side plate 102 is provided with a plurality of second connecting holes which are uniformly distributed along the edge of the electrical appliance mounting groove 103, the bolts pass through the corresponding first connecting holes and second connecting holes, and are fixed through the tightening action of the nuts, so as to realize the fixed connection of the electrical appliance cabinet cover 200 and the first side plate 102.

[0055] In some embodiments, the fixing side of the protrusion 201 is provided with a fixing edge 203, and the fixing edge 203 is used for fixedly connecting with the first side plate 102. Figure 4 Figure 5 As shown in FIGS. 1, 2, and 3, the first side plate 102 is further configured with a pipeline mounting port 1021, and the air duct machine further includes a pipe pressing plate 300 which is detachably mounted on the pipeline mounting port 1021, and the pipe pressing plate 300 is used for cooperating with the side wall of the pipeline mounting port 1021 to fix the refrigerant connecting pipe which passes through the pipeline mounting port 1021.

[0056] ​​​The pipeline mounting port 1021 is an opening on the first side plate 102 for the refrigerant connecting pipe of the heat exchanger to pass through. The heat exchanger is an important component in the ducted air conditioner, responsible for heat exchange. Through the pipeline mounting port 1021, the refrigerant connecting pipe of the heat exchanger can conveniently extend out of the cabinet 100 to connect with external pipelines. By setting the pipe pressing plate 300, the refrigerant connecting pipe can be pressed and fixed in cooperation with the pipeline mounting port 1021, ensuring that the refrigerant connecting pipe remains stable during the operation of the ducted air conditioner, avoiding loosening or falling off of the refrigerant connecting pipe due to vibration or other external forces, thereby ensuring the normal operation of the system.

[0057] In some embodiments, in combination with Figure 4 As shown, at least one first avoiding hole 1022 is arranged at the edge of the pipeline mounting port 1021, and a second avoiding hole 301 corresponding to the first avoiding hole 1022 is arranged at the edge of the pipe pressing plate 300, and the first avoiding hole 1022 and the corresponding second avoiding hole 301 can be combined to form a pipeline avoiding hole.

[0058] By arranging the first avoiding hole 1022 at the edge of the pipeline mounting port 1021, the refrigerant connecting pipe can be accurately and quickly positioned during installation, avoiding installation difficulties caused by mispositioning of the hole. The installer only needs to place the refrigerant connecting pipe in the corresponding first avoiding hole 1022 to complete the positioning of the refrigerant connecting pipe. The combined design of the first avoiding hole 1022 and the second avoiding hole 301 ensures that the pipeline can be stably fixed in the specified position after installation. The combined pipeline avoiding hole can limit the position of the refrigerant connecting pipe, preventing it from loosening or shifting during operation due to vibration or external forces, thereby improving the operation stability and reliability of the ducted air conditioner.

[0059] The first avoiding hole 1022 and the second avoiding hole 301 are both semicircular, and the first avoiding hole 1022 and the second avoiding hole 301 can be combined to form a circular pipeline avoiding hole.

[0060] In some embodiments, the pipe pressing plate 300 and the first side plate 102 of the cabinet 100 are detachably connected by bolts or buckles. By adopting the detachable connection mode of bolts or buckles, the assembly process of the pipe pressing plate 300 and the first side plate 102 does not require complex tools or additional steps, and the operator can quickly complete the installation or disassembly. For example, the buckle design can achieve the assembly effect of "one press, one fit", and the bolt connection simplifies the positioning through a standardized interface, significantly reducing the time and labor cost required by traditional welding or riveting processes, thereby improving the overall production efficiency.

[0061] The application further provides an air conditioner comprising the shell assembly. In the technical scheme, the assembly process of the air conditioner is simplified, and the production efficiency is improved. Meanwhile, the integral forming of the electrical installation groove enhances the overall structural strength, and avoids the problems of loosening and deformation in the transportation or use.

[0062] In some embodiments, the ducted air conditioner further comprises a partition plate, a fan and a heat exchanger, etc. The partition plate is arranged in the cabinet to divide the cabinet into a heat exchange cavity and a fan cavity. The partition plate divides the cabinet into the heat exchange cavity and the fan cavity, wherein the fan is arranged in the fan cavity, and the heat exchanger is arranged in the heat exchange cavity. In the operation process of the ducted air conditioner, the impeller of the fan is driven to rotate to generate airflow. The airflow enters the heat exchange cavity through the outlet of the volute, flows through the surface of the heat exchanger to exchange heat with the heat exchanger, and then enters the indoor to adjust the air quality in the indoor.

[0063] It should be noted that the preferred embodiments described above are only used to illustrate the principles of the application, and are not intended to limit the protection scope of the application. Those skilled in the art can adjust the above arrangement without departing from the principles of the application, so that the application can be applied to more specific application scenarios.
