Technical Field

[0001] The invention belongs to the field of air-conditioning chassis, and in particular relates to a chassis and a cabinet-type air-conditioner formed therefrom. Background Art

[0002] Nowadays, the indoor unit of a general cabinet air conditioner needs to be connected to three connecting pipes and a power cord to realize the normal operation of the indoor unit. Two of the connecting pipes are connected to the outdoor unit, one drain pipe is used to drain condensed water, and the power cord is connected to the power supply to provide power for the operation of the indoor unit.

[0003] At present, the three connecting pipes and the power cord are all led out through knock-out holes set on the left and right side panels or the rear side panels of the cabinet air conditioner. When setting the knock-out holes, the positions of the components inside the cabinet air conditioner shell need to be considered. In order to avoid exposing the components inside the shell, the apertures of the knock-out holes are relatively small.

[0004] In the prior art, the pipelines in the cabinet air conditioner can only be connected from a pre-set knock-out hole with a smaller aperture, which limits the external connection direction of the power cord and the drain pipe. At the same time, the adjustable range of the connecting pipe and the power cord after installation is small, resulting in the cabinet air conditioner can only be installed in a specific position, and the installation position cannot be selected and adjusted independently. Summary of the invention

[0005] The present invention aims to solve at least one of the problems in the related art to a certain extent. To this end, the present invention aims to provide a chassis and a cabinet air conditioner formed therefrom, which improve the stability and firmness of the chassis while allowing the external connection holes on the side walls to be opened larger, thereby making the range of choices for the external connection direction of the pipeline wider and the installation position more optional.

[0006] In order to achieve the above object, the present invention proposes the following technical solution: a chassis, comprising:

[0007] A connection surface for supporting equipment, and a chassis side wall connected to the connection surface;

[0008] A sink cavity is provided in the connection surface, and the bottom surface of the sink cavity is used as the placement surface of the chassis;

[0009] The side wall of the chassis is provided with an external connection hole for leading out pipelines, and the external connection hole is communicated with the connection surface.

[0010] Furthermore, a transit hole connected to the external connection hole is provided on the connection surface, and the aperture of the transit hole is smaller than the aperture of the external connection hole.

[0011] Furthermore, a first wiring groove for leading out pipelines is formed between the side wall of the sink cavity and the side wall of the chassis.

[0012] Furthermore, a transfer elbow is provided in the first wiring trough, the aperture of the transfer elbow is matched with the aperture of the transfer hole, and the transfer elbow is sleeved with the transfer hole.

[0013] Furthermore, the side wall of the sink cavity is provided with an inner cavity hole connected to the external hole, and the aperture of the inner cavity hole is smaller than the aperture of the external hole.

[0014] Furthermore, a raised rib is provided at the bottom of the sink cavity, and a second wiring groove for leading out pipelines is formed between the raised rib and the side wall of the sink cavity.

[0015] Furthermore, the cavity shape of the sink cavity is a symmetrical structure centered on the center of the chassis.

[0016] Furthermore, there are two sink cavities, and the two sink cavities are symmetrically distributed with the center of the chassis as the center.

[0017] Furthermore, it also includes a reinforcement module, which is arranged on one side of the side wall of the chassis, and the reinforcement module is a hollow groove on one side of the placement surface of the chassis, and a first reinforcing rib is arranged in the hollow groove.

[0018] A cabinet air conditioner comprises any one of the above-mentioned chassis.

[0019] Compared with the prior art, the above-mentioned technical solution provided by the present application has the following advantages: the bottom surface of the sink cavity provided in the present application is the placement surface of the chassis. When the chassis is placed on the ground, the bottom surface of the sink cavity is in contact with the ground, so that the gravity of the chassis and the equipment above it can be distributed between the side walls of the chassis and the bottom surface of the sink cavity, and no longer relies solely on the bottom edge of the side walls of the chassis for load-bearing; the sink cavity provided in the present application increases the stability of the chassis when it is placed, and enables the external connection holes on the side walls of the chassis to be enlarged, so that the range of options for the external connection direction of the power cord and the drain pipe is larger. When connecting the pipes after sales, the external connection direction and position can be better selected according to actual needs and conditions, so that the installation position of the cabinet air conditioner has a wider range of options.

Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0033] Please refer to the attached Figure 1-4 The present application provides a chassis, comprising a connecting surface 1 for supporting equipment, and a chassis side wall 7 connected to the connecting surface 1; a sinking cavity 4 is provided in the connecting surface 1, and the bottom surface of the sinking cavity 4 is used as the placement surface of the chassis; the chassis side wall 7 is provided with an external connection hole 5 for leading out pipelines, and the external connection hole 5 is connected to the connecting surface 1.

[0034] When the chassis of the present application is placed on the ground, the bottom surface of the sink cavity 4 is in contact with the ground, so that the gravity of the chassis and the equipment above it can be distributed between the chassis side wall 7 and the bottom surface of the sink cavity 4, rather than relying solely on the bottom edge of the chassis side wall for load bearing; the sink cavity 4 provided in the present application increases the stability of the chassis when it is placed, and enables the external connection hole 5 on the chassis side wall 7 to be opened larger, so that the range of choices for the external connection direction of the power cord and the drain pipe is larger, and when the after-sales wiring is connected, the external connection direction and position can be better selected according to actual needs and conditions, so that the installation position of the cabinet air conditioner can be selected in a wider range. In addition, compared with the structure of the air conditioner side wall for pipeline extraction in the prior art, the solution of the chassis side wall for pipeline extraction in the present application makes the pipeline and its extraction hole concentrated in the chassis at the bottom of the air conditioner, thereby making the wiring of the air conditioner neat and orderly.

[0035] The chassis structure of the present application is suitable for the indoor unit of a cabinet air conditioner. In order to facilitate the transportation of the cabinet air conditioner, the chassis should not be prepared with heavy sheet metal parts, but can only be prepared with light injection molded parts. The chamber structure of the sink cavity 4 makes it easier to demold the chassis after injection molding, and significantly improves the firmness of the chassis itself.

[0036] The external hole 5 of the present application is connected with the connection surface 1. The connection here has two meanings. The first one refers to the fact that there are components such as wiring grooves or transfer elbows 6 between the external hole 5 and the connection surface 1. Through these components, the external hole 5 and the connection surface 1 are connected to realize the pipeline lead-out. The second one refers to the fact that the external hole 5 and the connection surface 1 are connected in structure. At this time, the pipeline is led out through the external hole 5 after reasonable wiring above or inside the connection surface 1. In the above two cases, the pipelines in the equipment of the present application first pass through the connection surface 1 and then are led out through the external hole 5, so that the pipelines are led out from top to bottom. The whole wiring process is neat and orderly, avoiding the sharp bending of the pipeline that may be caused by the pipeline being directly led out from the equipment through the external hole 5, ensuring that the function of the pipeline is not affected.

[0037] The pipelines in this application include power lines and drainage pipes. In actual applications, the specific types and numbers of pipelines can be set according to the specific needs of the equipment above the chassis.

[0038] The change of the chassis structure of the present application makes the leading out of the pipelines in the chassis more neat and orderly. The specific wiring of the leading out of the pipelines in the present application is introduced below through Examples 1-3:

[0039] Example 1

[0040] In this embodiment, a transfer hole 2 connected to the external hole 5 is provided on the connection surface 1, and the diameter of the transfer hole 2 is smaller than the diameter of the external hole 5. In this embodiment, the pipeline is led out through the transfer hole 2 and the external hole 5 in sequence.

[0041] In the existing cabinet air conditioner, the pipelines are directly led out through the knock-out holes on the side panels of the air conditioner. In order to fix the pipelines and prevent them from shaking during the operation of the air conditioner, it is necessary to additionally provide a movable baffle on the inner wall of the side panel where the knock-out holes are located. After the power cord and the drain pipe are assembled, the baffle is moved to fix them. The additional installation of the baffle on the side panel of the air conditioner reduces the production efficiency of the air conditioner and increases the production cost.

[0042] The aperture of the transfer hole 2 of the present application is smaller than that of the external hole 5. Since the aperture of the transfer hole 2 is smaller, it can be used to fix the pipeline. When the pipeline fixed by the transfer hole 2 is led out through the external hole 5, there is no need to fix the pipeline at the position of the external hole 5. Compared with the solution of setting a baffle on the inner wall of the side plate of the air conditioner to fix the pipeline in the prior art, the chassis lead-out pipeline method designed in the present application not only provides a new pipeline lead-out structure, so that the installation position of the cabinet air conditioner can be selected in a wider range, but also does not need to add a baffle to fix the pipeline, thereby improving the production efficiency of the air conditioner and reducing the production cost at the same time.

[0043] In order to smoothly lead out the fixed pipeline from the external connection hole 5, a first wiring groove for leading out the pipeline is formed between the side wall of the sink cavity 4 and the side wall 7 of the chassis in this embodiment, and the pipeline fixed by the transfer hole 2 is led out to the external connection hole 5 through the first wiring groove. Among them, the width and shape of the first wiring groove are specifically determined according to the chamber shape of the sink cavity 4, and any space formed between the side wall of the sink cavity 4 and the side wall 7 of the chassis can be used as a part of the first wiring groove.

[0044] As a preferred embodiment, the transit hole 2 can be located outside the cavity of the sink cavity 4. At this time, the transit hole 2 is located on the connecting surface 1, and the external hole 5 is located between the connecting surface 1 and the placement surface of the chassis, so that the pipeline in the equipment passes through the transit hole 2, the first wiring groove and the external hole 5 are led out, and the pipeline is led out from top to bottom without excessive or large bends, ensuring that the pipeline is smoothly led out.

[0045] As a preferred embodiment, in this embodiment, a raised rib 42 is provided at the bottom of the sink cavity 4, and the raised rib 42 can be a cross-shaped raised rib located at the bottom of the sink cavity 4. The provision of the raised rib 42 facilitates demolding of the chassis after injection molding, and at the same time improves the strength of the entire sink cavity 4. At the same time, the raised rib 42 is located on one side of the placement surface of the chassis to form a cavity, which can also be used as part of the first wiring groove.

[0046] Example 2

[0047] This embodiment includes all the structures in Implementation 1. On this basis, this embodiment provides a transfer elbow 6 in the first lead groove, the aperture of the transfer elbow 6 is adapted to the aperture of the transfer hole 2, and the transfer elbow 6 is sleeved with the transfer hole 2.

[0048] In this embodiment, the aperture of the transfer elbow 6 is substantially the same as that of the transfer hole 2. After the transfer hole 2 fixes the pipeline, the transfer elbow 6 can continue to fix the pipeline to prevent the pipeline from being dispersed in the first wiring groove. The pipeline fixed by the transfer hole 2 and the transfer elbow 6 is then led out through the external hole 5.

[0049] In this embodiment, the transfer elbow 6 is located in the first wiring groove and is sleeved with the transfer hole 2. The specific sleeve connection method can be threaded connection or the like. The transfer elbow 6 is a hollow arc-shaped structure, including at least one obtuse bend, and the position of the end of the transfer elbow 6 relative to the transfer hole 2 can be freely adjusted by rotating the sleeve, ensuring that the transfer elbow 6 is always located between the transfer hole 2 and the external connection hole 5 to be led out.

[0050] After the pipeline is fixed for the first time through the transfer hole 2, it is fixed for the second time by the transfer elbow 6, and finally led out through the external hole 5. By setting the length of the transfer elbow 6, the second fixation of different ranges of the pipeline can be achieved. The existence of the transfer elbow 6 further ensures that the pipeline is led out neatly and orderly, avoiding transition bending in the first wiring groove. The transfer elbow 6 is nested outside the pipeline, and can also protect the pipeline from external damage.

[0051] Example 3

[0052] In this embodiment, the side wall of the sink cavity 4 is provided with an inner cavity hole connected to the external hole 5, and the diameter of the inner cavity hole is smaller than the diameter of the external hole 5. In this embodiment, the pipeline is led out through the inner cavity hole and the external hole 5 in sequence.

[0053] In the present application, the aperture of the inner cavity hole is smaller than that of the external hole 5. Since the aperture of the inner cavity hole is smaller, it can be used to fix the pipeline. When the pipeline fixed by the inner cavity hole is led out through the external hole 5, there is no need to fix it at the position of the external hole 5, and there is no need to add a baffle. Compared with the solution of adding a baffle for fixing in the prior art, the chassis structure of the present application reduces the production process and reduces the production cost.

[0054] In order to allow the fixed pipeline to be smoothly led out from the external connection hole 5, a raised rib 42 is provided at the bottom of the sink cavity 4 in this embodiment, and a second wiring groove for leading out the pipeline is formed between the raised rib 42 and the side wall of the sink cavity 4. The pipeline in the device passes through the second wiring groove to reach the inner cavity hole, and then leads out through the external connection hole 5. The width and shape of the second wiring groove are specifically determined according to the shape and position of the raised rib 42. For example, the raised rib 42 can be a cross-shaped raised rib located at the bottom of the sink cavity 4.

[0055] The raised ribs 42 not only form the second wiring groove, but also facilitate demoulding of the chassis after injection molding, and at the same time improve the strength of the entire sink cavity 4.

[0056] It can be seen from the above embodiments 1-3 that the external hole 5 of the present application is connected to the connecting surface 1, and the pipeline in the equipment first passes through the connecting surface 1 and then is led out through the external hole 5. The wiring can be carried out by using the second wiring groove formed in the internal space of the sink cavity 4, or by using the first wiring groove formed by the side wall of the sink cavity 4 and the side wall of the chassis. The pipeline is led out from top to bottom, and the entire wiring process is neat and orderly, avoiding the sharp bending of the pipeline that may be caused by leading the pipeline directly from the equipment through the external hole, thereby ensuring that the function of the pipeline is not affected.

[0057] It is worth noting that in the above embodiment 3, a transfer elbow 6 as in embodiment 2 can also be arranged inside the sink cavity 4. In this case, the aperture of the transfer elbow 6 matches the aperture of the inner cavity hole, and the transfer elbow 6 is sleeved with the inner cavity hole. The pipelines of the equipment above the chassis are led out through the transfer elbow 6, the inner cavity hole and the external connection hole 5 in sequence.

[0058] It is worth noting that, when the inner cavity hole is far from the external hole 5 in Example 3, a transfer elbow 6 can also be arranged between the inner cavity hole and the external hole 5. At this time, the aperture of the transfer elbow 6 matches the aperture of the inner cavity hole, and the transfer elbow 6 is sleeved with the inner cavity hole. The pipelines of the equipment above the chassis are led out through the inner cavity hole, the transfer elbow 6 and the external hole 5 in sequence.

[0059] It is worth noting that the pipelines in the above embodiments include power lines and drainage pipes, and the specific numbers of the transfer holes 2, the inner cavity holes, the transfer elbows 6 and the external connection holes 5 can be adjusted according to the number of specific pipelines. No further details will be given here.

[0060] As a specific embodiment, as shown in the attached Figure 1 As shown, the cavity shape of the sink cavity 4 in the present application is a symmetrical structure centered on the center of the chassis. The symmetrical cavity structure can ensure that the chassis is subjected to uniform force and ensure the stability of the chassis placement.

[0061] As another specific embodiment, in the present application, there are two sinker cavities 4, and the two sinker cavities 4 are symmetrically distributed around the center of the chassis, ensuring that the chassis is evenly stressed and the stability of the chassis placement is ensured. The chassis including two sinker cavities in the injection molding mold design is easier to design, reducing the design difficulty during the chassis injection molding process.

[0062] It is worth noting that the cavity position and shape setting of the sink cavity 4 need to ensure that the first wiring groove or the second wiring groove in Examples 1-3 can be formed. At the same time, in the embodiment where a switching elbow is provided, it is also necessary to reserve rotation space for the switching elbow 6.

[0063] In order to further improve the sturdiness of the chassis, the present application also includes a reinforcement module 8, which is arranged on one side of the chassis side wall 7, and the reinforcement module 8 is a hollow groove on one side of the placement surface of the chassis, and a first reinforcing rib 81 is arranged in the hollow groove.

[0064] In order to further improve the firmness of the chassis, a second reinforcing rib 41 is provided between the side wall of the sink cavity and the reinforcement module 8 and / or the side wall 7 of the chassis. Figure 4 shown.

[0065] Please refer to the attached Figure 5-6 The present application also provides a cabinet air conditioner, including a chassis of any of the above embodiments, and the chassis of any of the above embodiments is applied to the indoor unit of the cabinet air conditioner, and an air inlet baffle 82 is arranged on the front of the reinforcement module to form an air inlet of the indoor unit.

[0066] Finally, through the specific embodiment 4 and the attached Figure 1-6 Further explanation of this application:

[0067] Example 4

[0068] A chassis comprises: a connection surface 1 for supporting equipment, and a chassis side wall 7 connected to the connection surface 1; a sink cavity 4 is provided in the connection surface 1, and the bottom surface of the sink cavity 4 is used as the placement surface of the chassis; and an external connection hole 5 for leading out pipelines is provided on the chassis side wall 7. In this embodiment, the pipelines are specifically power lines and drainage pipes.

[0069] A transit hole 2 connected to the external hole 5 is provided on the connection surface 1, and the aperture of the transit hole 2 is smaller than the aperture of the external hole 5. In this embodiment, a first wiring groove for leading out pipelines is formed between the side wall of the sink cavity 4 and the side wall 7 of the chassis, and a switching elbow 6 is provided in the first wiring groove. The transit hole 2 of this embodiment is located at the center of the connection surface 1, and the transit hole 2 specifically includes a knock-out hole 21 and a threaded hole 22, which are used to lead out the power cord and the drain pipe, respectively. The aperture of the knock-out hole 21 is slightly larger than the outer diameter of the power cord, and the aperture of the threaded hole 22 is slightly larger than the outer diameter of the drain pipe.

[0070] In order to facilitate the arrangement of the knock-out hole 21 and the threaded hole 22, the present embodiment is provided with an opening surface 11 at the center of the connection end surface 1, the opening surface 11 is located between the connection surface 1 and the placement surface of the chassis, the outer side of the opening surface 11 is the sink cavity 4, and the knock-out hole 21 and the threaded hole 22 are arranged in the opening surface 11. A groove with an area much smaller than the chamber area of ​​the sink cavity is formed between the opening surface 11 and the side wall of the sink cavity 4, and the groove can be used to store the redundant part of the pipeline.

[0071] The shape of the sink cavity 4 is a symmetrical structure centered on the center of the chassis. The sink cavity 4 is arranged around the knock-out hole 21 and the threaded hole 22, and a gap is reserved. At the end of the gap facing the placement surface of the chassis, the transfer elbow 6 can be freely rotated to different directions, so that the drainage pipe passing through the transfer hole 2 can be extended in different directions. At the same time, the symmetrically arranged sink cavity 4 can ensure that the force on both sides of the chassis is balanced, and the placement stability of the chassis is enhanced.

[0072] The knock-out hole 21 can be knocked out when in use, and is used to lead out the power cord. The threaded hole 22 is threadedly connected to the adapter elbow 6 on one side of the placement surface close to the chassis, and the threaded hole 22 and the adapter elbow 6 are adapted to lead out the drain pipe. The thread can be a raised internal thread or a raised external thread set at one end of the threaded hole 22, or a thread on the inner wall of the threaded hole 22; the adapter elbow 6 is a hollow arc-shaped structure, and its aperture is equal to the aperture of the threaded hole 22; and the adapter elbow 6 includes at least one obtuse bend, and the adapter elbow 6 is located in the notch reserved in the sink cavity 4 inside the side wall 7 of the chassis. The threaded connection between the adapter elbow 6 and the threaded hole 22 can freely change the position of the end of the adapter elbow relative to the threaded hole 22, so that the drain pipe can be led out through the external holes 5 in different directions.

[0073] A cross-shaped raised rib 42 is arranged inside the cavity of the sink cavity 4. The design of the cross-shaped raised rib 42 facilitates demoulding of the chassis after the chassis is injection molded, and is also conducive to strengthening the overall strength of the sink cavity and the chassis.

[0074] In this embodiment, the overall structure of the chassis can be designed as a rectangle, wherein the connection surface 1 and the chassis side wall 7 form the main structure of the chassis, which is used to lead out various pipelines above the chassis; the reinforcement module 8 is located in front of the main structure, which is used to reinforce the chassis as a whole. The reinforcement module 8 is arranged on one side of the chassis side wall 7, and the reinforcement module 8 is a hollow groove on one side of the placement surface of the chassis, and a first reinforcing rib 81 is arranged in the hollow groove.

[0075] In this embodiment, the external connection hole 5 can be opened in the left side wall, the right side wall and the rear side wall of the chassis side wall, and the front side wall is connected to the side wall of the reinforcement module 8 through the second reinforcing rib 41. At the same time, the second reinforcing rib 41 is also provided between the side wall of the sink cavity and the chassis side wall 7. The first reinforcing rib 81 and the second reinforcing rib 41 are both used to enhance the firmness of the chassis in this application.

[0076] In this embodiment, the drain pipe with a larger outer diameter is led out through the threaded hole 22, the adapter elbow 6 and the external pipe in sequence, and the threaded hole 22 and the adapter elbow 6 are used to fix the drain pipe, replacing the baffle on the side wall of the chassis in the prior art; at the same time, the aperture of the external hole 5 is much larger than the threaded hole 22, so that the range of selectable external orientations of the drain pipe is increased.

[0077] In this embodiment, the power cord with a smaller outer diameter is led out through the knock-out hole 21 and the external connection hole 5 in turn, and the knock-out hole 21 is used to fix the power cord, replacing the baffle on the side wall of the chassis in the prior art; at the same time, the hole diameter of the external connection hole 5 is much larger than the knock-out hole 21, so that the range of selectable external connection orientations of the power cord is increased.

[0078] This embodiment expands the range of external connection options for power cords and drain pipes. When installing after-sales wiring and pipes, the external connection direction and position can be better selected according to actual needs and conditions, thereby making the range of installation location options for the cabinet air conditioner wider.

[0079] Please refer to the attached Figure 5-6 In this embodiment, when the chassis is located in the indoor unit of the cabinet air conditioner, an air inlet baffle 82 is provided on the front of the reinforcement module 8 to form an air inlet of the indoor unit.

[0080] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
