Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a cabinet assembly and an air conditioner. BACKGROUND

[0002] As a core component of an air conditioning system, the installation quality of a ducted air conditioner directly affects the stability and service life of the equipment. Among them, the water pan and the drain pipe of the ducted air conditioner are key functional components for condensate water discharge, and the structural reliability thereof has an important influence on the overall performance of the machine.

[0003] In the related art, the ducted air conditioner includes a water pan and a drain pipe arranged on the water pan, and the drain pipe extends to the outside of the cabinet of the ducted air conditioner. However, although there is a clear prohibition of lifting the pipe sign on the equipment, during actual installation operation, the installer still has the operation behavior of holding the drain pipe to carry the ducted air conditioner, which can cause damage to the connection between the drain pipe and the water pan, resulting in condensate water leakage problems, and seriously affecting the use performance of the equipment and the user experience.

[0004] Correspondingly, there is a need in the art for a new technical solution to solve the above problems. UTILITY MODEL CONTENT

[0005] In order to solve at least one of the above problems in the prior art, that is, to solve the technical problem that in actual installation operation, the installer has the operation behavior of holding the drain pipe to carry the ducted air conditioner, which can cause damage to the connection between the drain pipe and the water pan, resulting in condensate water leakage problems, and seriously affecting the use performance of the equipment and the user experience.

[0006] In a first aspect, the present application provides a cabinet assembly, which includes: a cabinet, a first through hole being formed in a side wall of the cabinet; and a water pan, arranged in the interior of the cabinet, the water pan including a windward side and a drainage side connected with the windward side, a connection between the windward side and the drainage side being recessed inward to form an avoiding gap; and a drain connector, arranged in the water pan, for draining water accumulated in the water pan, wherein the drain connector is located in the avoiding gap and extends outward to the inside of the first through hole.

[0007] In the case of adopting the above technical solution, the windward side of the water pan and the connection between the windward side and the drainage side are recessed inward to form an avoiding gap, and the drain connector is arranged in the avoiding gap and completely located inside the cabinet, which eliminates the exposed drain pipe in the related art, fundamentally eliminates the operation behavior of the installer holding the drain connector to carry the ducted air conditioner, and can reduce the possibility of damage to the drain connector and the water pan during carrying, and reduce the possibility of condensate water leakage.

[0008] In some embodiments, the length of the avoiding gap is greater than 30 mm and less than 120 mm along the extension direction of the windward side.

[0009] By limiting the length of the avoidance gap to the above range, it is ensured that the avoidance gap has sufficient space to accommodate the drain connector and its connecting pipeline, ensuring that the condensed water can be smoothly drained, and avoiding the problem of poor drainage or water accumulation due to insufficient space. At the same time, it can prevent the water pan from being excessively recessed, ensuring the drainage function while maintaining the overall structural strength of the water pan, avoiding stress concentration or structural deformation caused by excessive recessing.

[0010] In some embodiments, the cabinet comprises a bottom plate, wherein a region corresponding to the drain connector on the bottom plate is provided with a mounting gap.

[0011] By providing a mounting gap, it is convenient for the operator to connect the drain connector 300 with the connecting pipeline, and it is also convenient for subsequent maintenance and maintenance operation

[0012] In some embodiments, the cabinet further comprises a mounting cover plate, wherein the mounting cover plate is detachably mounted on the mounting gap.

[0013] The mounting cover plate closes the mounting gap during equipment operation, preventing dust, debris, and other foreign matter from entering the cabinet interior and affecting normal operation of the equipment. The design of the mounting cover plate makes the drain connector area flush with the outer surface of the cabinet, improving the overall integrity and aesthetics of the equipment appearance. When it is necessary to connect the drain connector with the connecting pipeline, the mounting cover plate is removed, facilitating the installation personnel to operate.

[0014] In some embodiments, the cabinet further comprises a first side wall near the avoidance gap, and the first through hole is provided on the first side wall; wherein the first side wall extends along the avoidance gap, or the first side wall is a planar plate structure.

[0015] By making the first side wall a planar plate structure, the overall integrity and aesthetics of the air duct machine appearance can be ensured, and by making the first side wall extend along the avoidance gap, different installation requirements can be met.

[0016] In some embodiments, the water pan and the drain connector are integrally foamed and formed.

[0017] The integral foaming molding eliminates the connection gap between the water pan and the drain connector, avoids the condensate leakage problem caused by loose connection, and ensures the sealing and reliability between the water pan and the drain connector. At the same time, the integral foaming molding makes the water pan and the drain connector form a continuous whole structure, reduces the connecting parts and sealing materials required in the traditional assembly method, reduces the complexity of the structure, and significantly improves the mechanical strength and impact resistance of the local area. In addition, the integral foaming molding structure has completed the integration of the water pan and the drain connector when leaving the factory, and does not need additional assembly during on-site installation, simplifying the installation process, improving the installation efficiency, avoiding the problems such as misalignment and poor sealing that may occur during on-site assembly, and improving the consistency of installation quality.

[0018] In some embodiments, the material of the drain connector is polycarbonate.

[0019] By making the material of the drain connector polycarbonate, it can withstand the high temperature environment during foaming and resist the long-term erosion of condensate water and mechanical stress during use, ensuring the long-term reliability of the drain connector.

[0020] In some embodiments, the material of the water pan is foamed polystyrene.

[0021] The polystyrene foam board is light and has good thermal insulation performance, which can play a certain heat preservation role and reduce the overall weight of the water pan. At the same time, foamed polystyrene has good aging resistance and water resistance, which can keep the material performance stable in long-term use and prolong the service life of the water pan. In addition, the water pan made of foamed polystyrene has good shock absorption and buffering performance, which can reduce vibration and noise during equipment operation.

[0022] In a second aspect, the application provides an air conditioner, which comprises the above-mentioned cabinet assembly.

[0023] The air conditioner provided by the application fundamentally eliminates the operation behavior of the installer holding the drain connector to carry the ducted air conditioner, can reduce the possibility of damage to the drain connector and the water pan during carrying, reduce the possibility of condensate leakage, and improve the user experience.

[0024] In some embodiments, the air conditioner further comprises a heat exchanger, which is inclinedly arranged above the water pan, and the projection of the heat exchanger on the water pan falls into the water pan.

[0025] The water pan can receive and collect the condensate water dripping from the heat exchanger. BRIEF DESCRIPTION OF DRAWINGS

[0039] In the present application, “a plurality of” means two or more.

[0040] In addition, it needs to be explained that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected. It can be mechanical connection, or electrical connection. It can be direct connection, or indirect connection through intermediate medium, or internal communication of 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.

[0041] As the core component of air conditioning system, the installation quality of ducted air conditioner directly affects the stability of equipment operation and service life. Among them, the water pan and the drain pipe of the ducted air conditioner as the key functional components of condensate water discharge, the structural reliability has important influence on the performance of the whole machine.

[0042] In the related art, the ducted air conditioner includes a water pan and a drain pipe arranged on the water pan, and the drain pipe extends to the outside of the cabinet of the ducted air conditioner. However, although there is a clear prohibition of lifting pipe sign on the equipment, in the actual installation operation, the installation personnel still have the operation behavior of holding the drain pipe to carry the ducted air conditioner, which will cause damage to the connection between the drain pipe and the water pan, causing condensate leakage problem, and seriously affecting the use performance of the equipment and user experience.

[0043] The present application provides a cabinet assembly and an air conditioner, which can eliminate the operation behavior of holding the drain pipe to carry the ducted air conditioner, can reduce the possibility of damage to the drain joint and the water pan during carrying, and reduce the possibility of condensate leakage.

[0044] In a first aspect, the present application provides a cabinet assembly.

[0045] In combination Figure 1 And Figure 2 As shown in the cabinet assembly provided by the present application includes a cabinet 100, a water pan 200 and a drain joint 300.

[0046] The side wall of the cabinet 100 is provided with a first through hole 101.

[0047] The water pan 200 is arranged in the interior of the cabinet 100, and the water pan 200 includes a windward side 201 and a drain side 202 connected with the windward side 201, and the connection between the windward side 201 and the drain side 202 is inwardly recessed to form a relief gap 203. The water pan 200 has a water receiving groove with an opening facing upward, for receiving and discharging the condensate water dripping from the heat exchanger.

[0048] The drain connector 300 is arranged on the water pan 200 and is used to drain the accumulated water in the water pan 200. The drain connector 300 is located in the avoiding gap 203 and extends outward to the inner side of the first through hole 101. The drain connector 300 is arranged on the water pan 200 and is in communication with the water receiving groove of the water pan 200. The condensed water in the water receiving groove flows out along the drain connector 300.

[0049] In the technical solution, the connection part between the windward side 201 and the drain side 202 of the water pan 200 is inwardly recessed to form the avoiding gap 203. The drain connector 300 is arranged in the avoiding gap 203 and is completely located on the inner side of the cabinet 100. Thus, the exposed drain pipe in the related art is eliminated. The operation behavior of the installer holding the drain connector 300 to carry the air pipe machine is fundamentally eliminated. The possibility of damage to the drain connector 300 and the water pan 200 during carrying is reduced. The possibility of condensed water leakage is reduced.

[0050] In some embodiments, the length of the avoiding gap 203 along the extension direction of the windward side 201 is greater than 30 mm and less than 120 mm. For example, the length of the avoiding gap 203 along the extension direction of the windward side 201 is 35 mm, 50 mm, 60 mm, 100 mm, 110 mm, or the like. The length of the avoiding gap 203 can be flexibly set according to actual needs.

[0051] By limiting the length of the avoiding gap 203 in the above range, the minimum length limit of 30 mm ensures that the avoiding gap 203 has enough space to accommodate the drain connector 300 and the connecting pipeline, ensures that the condensed water can be smoothly drained, and avoids the problem of poor drainage or water accumulation due to insufficient space. The maximum length limit of 120 mm prevents the water pan 200 from being excessively recessed. While ensuring the drainage function, the overall structural strength of the water pan is maintained, and stress concentration or structural deformation due to excessive recess is avoided. At the same time, the length range of 30 mm to 120 mm of the avoiding gap 203 provides enough operation space for the installer, which facilitates the connection, fixation, and subsequent maintenance of the drain connector 300 and the connecting pipeline.

[0052] In some embodiments, in combination with Figure 1 As shown, the cabinet 100 includes a bottom plate 102. A region of the bottom plate 102 corresponding to the drain connector 300 is provided with a mounting gap 1021.

[0053] The drain connector 300 is in communication with the connecting pipeline and drains the condensed water to the outside of the cabinet 100 through the connecting pipeline. By arranging the mounting gap 1021, the operator can conveniently connect the drain connector 300 and the connecting pipeline, and facilitate subsequent maintenance and maintenance operations.

[0054] In some embodiments, in combination with Figure 3As shown, the cabinet 100 further comprises a mounting cover plate 103, wherein the mounting cover plate 103 is detachably mounted on the mounting gap 1021.

[0055] The mounting cover plate 103 seals the mounting gap 1021 during operation of the device, preventing dust, debris, and the like from entering the interior of the cabinet and affecting normal operation of the device. The design of the mounting cover plate 103 makes the area of the drain connector 300 flush with the outer surface of the cabinet 100, improving the overall integrity and aesthetics of the appearance of the device. When it is necessary to connect the drain connector 300 to the connecting pipeline, the mounting cover plate 103 is removed, facilitating the operation of the installer.

[0056] Optionally, the mounting cover plate 103 and the mounting gap 1021 are detachably connected by bolts or buckles. By using the detachable connection mode of bolts or buckles, the assembly process of the mounting cover plate 103 and the mounting gap 1021 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 and one fit", while 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.

[0057] In some embodiments, in combination with Figure 2 , Figure 4 and Figure 5 As shown, the cabinet 100 further comprises a first side wall 104 adjacent to the avoidance gap 203, and the first through hole 101 is arranged on the first side wall 104. The first side wall 104 extends along the avoidance gap 203, or the first side wall 104 is a planar plate structure. By arranging the first through hole 101, the drain connector 300 is provided with multiple connection modes, such as being connected to the connecting pipeline in a bent manner or being connected to the connecting pipeline in a straight line, so that it can adapt to various installation environments. By making the first side wall 104 a planar plate structure, the overall integrity and aesthetics of the appearance of the air duct machine can be ensured, and by making the first side wall 104 extend along the avoidance gap 203, different installation requirements can be met.

[0058] In some embodiments, the water pan 200 and the drain connector 300 are integrally foamed. The water pan 200 and the drain connector 300 integrally foamed means that the water pan 200 and the drain connector 300 are manufactured as a whole structure through a foaming process.

[0059] The one-piece foaming molding eliminates the connection gap between the water pan 200 and the drain connector 300, avoids the condensate leakage problem caused by loose connection, and ensures the sealing and reliability between the water pan 200 and the drain connector 300. At the same time, the one-piece foaming molding makes the water pan 200 and the drain connector 300 form a continuous whole structure, reduces the connecting parts and sealing materials required in the traditional assembly method, reduces the complexity of the structure, and significantly improves the mechanical strength and impact resistance of the local area. In addition, the one-piece foaming molding structure has completed the integration of the water pan 200 and the drain connector 300 when leaving the factory, and does not need additional assembly during on-site installation, simplifying the installation process, improving the installation efficiency, avoiding the problems such as misalignment and poor sealing that may occur during on-site assembly, and improving the consistency of installation quality.

[0060] The foaming process is a technology for forming a bubble structure inside a material through physical or chemical methods, and is widely used in the manufacture of lightweight and porous materials. The forming process of the bubble is first to dissolve the gas in the liquid polymer or heat the polymer to the molten state, while generating gas and forming a saturated solution, then forming countless tiny bubble nuclei through nucleation. Then it expands into a foam with the required foam structure, and finally the structure of the foam is fixed by assimilation, and the foam plastic product is obtained. Commonly used foaming materials include EPS (foamed polystyrene), EPP (foamed polypropylene) and PU (polyurethane) etc. Foaming process has the advantages of lightweight, heat insulation, sound insulation, impact resistance, etc., and is widely used in packaging, building, automobile, household appliances and other fields.

[0061] In some embodiments, the material of the drain connector 300 is polycarbonate. Polycarbonate (PC) is a colorless and transparent thermoplastic material with excellent impact resistance, heat resistance and stability. By making the material of the drain connector 300 polycarbonate, it can withstand the high temperature environment during foaming, resist the long-term erosion of condensate water and mechanical stress during use, and ensure the long-term reliability of the drain connector 300.

[0062] In some embodiments, the material of the water pan 200 is foamed polystyrene.

[0063] Polystyrene foam board (EPS) is lightweight and has good heat insulation performance, which can play a certain heat preservation role and reduce the overall weight of the water pan. At the same time, foamed polystyrene has good aging resistance and water resistance, which can keep the material performance stable in long-term use and prolong the service life of the water pan 200. In addition, the water pan 200 made of foamed polystyrene material has good shock absorption and buffering performance, which can reduce vibration and noise during equipment operation.

[0064] In a second aspect, the application also provides an air conditioner.

[0065] The air conditioner provided by the application comprises the cabinet assembly of any one of the above.

[0066] In the air conditioner provided by the application, the windward side 201 of the water pan 200 is connected to the drainage side 202, and the connection is inwardly recessed to form a relief gap 203. The drainage connector 300 is arranged in the relief gap 203 and is completely located on the inner side of the cabinet 100. Thus, the exposed drainage pipe in the related art is eliminated, the operation behavior of the installer holding the drainage connector 300 to carry the air pipe machine is fundamentally eliminated, the possibility of damage to the drainage connector 300 and the water pan 200 during carrying is reduced, the possibility of condensate leakage is reduced, and the use experience of the air conditioner is improved.

[0067] In some embodiments, in combination with Figure 1 As shown, the air conditioner further comprises a heat exchanger 400, which is arranged obliquely above the water pan 200, and the projection of the heat exchanger 400 on the water pan 200 falls into the water pan 200. The airflow flows through the heat exchanger 400, exchanges heat with the heat exchanger 400, and then enters the indoor space, thereby providing heat or cold to the indoor space. The condensate on the heat exchanger 400 flows downward along the heat exchanger to the bottom of the heat exchanger 400, and then drips into the water pan 200. Alternatively, the condensate on the heat exchanger 400 directly drips into the water pan 200, so that the condensate can be better collected.

[0068] It should be noted that the above preferred embodiments 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.

[0069] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means to be within the scope of the application and form different embodiments. For example, in the claims of the application, any one of the claimed embodiments can be used in any combination.
