Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner and a pipeline sealing component thereof. Background Art

[0002] Split-type air conditioners typically feature an indoor unit and an outdoor unit, connected by interconnecting piping. Because the piping needs to adapt to different building structures and indoor unit installation locations, the location where the interconnecting piping enters the indoor unit varies significantly. To address this issue, related art incorporates multiple knockout holes in various locations within the indoor unit housing. During installation, these knockout holes are removed as needed to create access holes, which are then connected to the indoor unit through the access holes.

[0003] However, once the knockout hole is knocked out, it cannot be restored. When the installation position of the indoor unit needs to be changed, the original knockout hole will affect the sealing of the air conditioner, causing dust, foreign matter, etc. to enter the air conditioner. Utility Model Content

[0004] In view of the above problems, the present invention is proposed to provide an air conditioner and its pipeline sealing assembly that overcome the above problems or at least partially solve the above problems, aiming to solve the problem that the pipeline access hole of the existing air conditioner cannot be reused.

[0005] Specifically, the present invention provides the following technical solutions:

[0006] A pipeline sealing assembly for an air conditioner comprises a base plate and a baffle.

[0007] A first pipeline hole is provided on the substrate, and the length of the first pipeline hole is greater than the width.

[0008] The baffle is formed by detachably joining a first baffle and a second baffle, and a second pipeline hole is provided at the joint, the second pipeline hole matches the pipeline of the air conditioner, and the second pipeline hole is slidably connected to the base plate through the baffle.

[0009] On a projection plane parallel to the substrate, the second pipeline hole is located inside the first pipeline hole, and the baffle covers the first pipeline hole.

[0010] Optionally, the first pipeline hole extends along a first direction.

[0011] The second pipeline hole is slidably arranged along the first direction.

[0012] Optionally, a sliding groove extending along the first direction is provided on the inner side of the base plate, and the baffle is slidably installed on the inner side of the base plate through the sliding groove.

[0013] Optionally, the first baffle is slidably mounted on the base plate via the sliding groove, and the second baffle is detachably fixedly connected to the first baffle.

[0014] Optionally, the first baffle and the second baffle are both slidably connected to the sliding groove.

[0015] Optionally, the first end of the first baffle away from the second pipeline hole is fixedly arranged, and the second end of the first baffle away from the first end is telescopically arranged along the first direction.

[0016] The third end of the second baffle away from the second pipeline hole is fixedly arranged, and the fourth end of the second baffle away from the third end is telescopically arranged along the first direction.

[0017] Optionally, the first direction is the length direction of the air conditioner.

[0018] On the other hand, the present application also provides an air conditioner, comprising a housing, a pipeline and the above-mentioned pipeline sealing assembly. The substrate is arranged on the housing.

[0019] Optionally, the housing forms the substrate.

[0020] Optionally, an air duct and a heat exchanger located in the air duct are further provided in the shell.

[0025] The utility model relates to an air conditioner and its pipeline sealing assembly, which are provided with a first pipeline hole and a second pipeline hole with a larger length. The pipeline is inserted into the second pipeline hole, and the shape and size of the second pipeline hole match the pipeline to achieve sealed installation. The second pipeline hole changes its position by sliding along the length direction of the first pipeline hole, thereby changing the access position of the pipeline and achieving matching with different building structures and installation positions. When the installation position of the air conditioner is changed, the second pipeline hole can be slid again to adapt to the new access position. On the other hand, the second pipeline hole is formed by splicing the first baffle and the second baffle. When connecting the pipeline, it is only necessary to pass the pipeline through the first pipeline hole with a larger length, and then splice the first baffle and the second baffle together. The pipeline does not need to pass through the second pipeline hole with a smaller size, which is more convenient to operate and achieves the effect of improving installation efficiency.

[0043] Figure 1 Schematic diagram of the structure of an air conditioner according to an embodiment of the present invention. Figure 1 As shown, and reference Figure 2-9 The embodiment of the present invention provides a pipeline sealing assembly 100 for an air conditioner, comprising a base plate 110 and a baffle 120 .

[0044] A first pipeline hole 130 is provided on the base plate 110. The length L of the first pipeline hole 130 is greater than the width W. The baffle 120 is formed by detachably joining a first baffle 122 and a second baffle 124. A second pipeline hole 140 is provided at the joint. The second pipeline hole 140 mates with the air conditioner pipeline 200 and is slidably connected to the base plate 110 through the baffle 120.

[0045] On a projection plane 600 parallel to the substrate 110 , the second pipeline hole 140 is located inside the first pipeline hole 130 , and the baffle 120 covers the first pipeline hole 130 .

[0046] The pipeline 200 of the air conditioner usually includes a refrigerant pipe (such as an air pipe, a liquid pipe, etc.), an electric cable, a drain pipe, etc., and a heat-insulating protective layer can also be set on the outer ring of the pipeline 200. The pipeline 200 is set between the indoor unit and the outdoor unit, and usually needs to pass through a perforation set on the wall of the building. When the air conditioner is an embedded air conditioner and is embedded in a furniture cabinet (such as a cupboard, a TV cabinet, a wardrobe, etc.), the pipeline 200 also needs to pass through a perforation set on the partition. Whether it is a perforation on the wall or a perforation on the partition, the position is relatively fixed. When installing the indoor unit, the pipeline 200 needs to be reasonably routed to facilitate the connection of the pipeline 200 to the indoor unit.

[0047] In this embodiment, the substrate 110 can be disposed on the housing 300 of the indoor unit. If the air conditioner is a built-in air conditioner, the substrate 110 can also be disposed on the frame of the indoor unit (a built-in air conditioner may not have a complete housing 300). Of course, the substrate 110 can also be formed by the housing 300 or the frame, that is, the substrate 110 is a partial structure on the housing 300 or the frame.

[0048] The first pipeline hole 130 can be a straight long waist hole, or an overall arc-shaped hole, a curved hole, or a circular ring hole, and can be set according to actual needs. The length direction of the first pipeline hole 130 is its extension direction. For example, when the first pipeline hole 130 is a circular ring hole, the length direction is a concentric circle passing through the center of the ring. Since the first pipeline hole 130 has a relatively large length, on the one hand, it allows a larger selection space for the access position of the pipeline 200. On the other hand, the hardness of the pipeline 200 is generally large, and due to the conditions at the construction site, the accuracy of the pipeline 200 when manually bent is not high. The larger length of the first pipeline hole 130 can absorb the error when manually bending the pipeline 200, making it easier to operate and install the pipeline 200.

[0049] The width of first pipeline hole 130 is greater than or equal to the diameter of pipeline 200 to facilitate passage of pipeline 200 through first pipeline hole 130. In some embodiments, a connector is provided at the end of pipeline 200 for docking with the air conditioner heat exchanger 500. The width of first pipeline hole 130 should also be greater than the diameter of the connector to facilitate passage of the connector.

[0050] Second pipeline hole 140 is formed by the first baffle 122 and the second baffle 124. After pipeline 200 passes through first pipeline hole 130, first baffle 122 and second baffle 124 are aligned on opposite sides of pipeline 200 to form second pipeline hole 140. First baffle 122 and second baffle 124 wrap around the outer circumference of the cross-section of pipeline 200.

[0051] The first baffle 122 and the second baffle 124 can be removably fixedly connected by plugging, snapping, fasteners, or other means. Of course, the first baffle 122 and the second baffle 124 can also be connected separately to the base plate 110 to achieve splicing. To connect the pipeline 200, simply pass the pipeline 200 through the longer first pipeline hole 130 and then splice the first baffle 122 and the second baffle 124 together. The pipeline 200 does not need to pass through the smaller second pipeline hole 140, making the operation more convenient and improving installation efficiency.

[0052] The shape and size of second pipeline hole 140 match pipeline 200 to minimize the gap between pipeline 200 and the wall of second pipeline hole 140, thereby achieving a sealed installation and preventing dust, foreign matter, etc. from entering the air conditioner. If second pipeline hole 140 is a circular hole, the seam between first baffle 122 and second baffle 124 should extend through the diameter of the circular hole.

[0053] In this embodiment, the baffle 120 can be attached to the outside or inside of the base plate 110. The second pipeline hole 140 can slide along the length of the first pipeline hole 130. In other words, the first baffle 122 and the second baffle 124 can slide along the base plate 110 at least at the joint.

[0054] In this embodiment, the substrate 110 may be a plane (eg Figure 6 As shown in FIG), it can also be a curved surface (such as a cylindrical surface). When the substrate 110 is a cylindrical surface, as shown in FIG. Figure 7 As shown, baffle 120 can be a cylindrical surface concentric with the cylindrical surface, and projection surface 600 can be a concentric cylindrical surface. Regardless of how second pipeline hole 140 slides, it remains within first pipeline hole 130 on projection surface 600. In other words, the movement of second pipeline hole 140 is limited to along the length of first pipeline hole 130. Regardless of how second pipeline hole 140 slides, baffle 120 always covers first pipeline hole 130 on projection surface 600. This ensures that baffle 120 consistently seals and covers first pipeline hole 130, preventing dust, foreign matter, and other objects from entering the air conditioner.

[0055] In the pipeline sealing assembly 100 of the present invention, the second pipeline hole 140 slides along the length of the first pipeline hole 130 to adjust its position, thereby changing the connection position of the pipeline 200, thereby adapting to different building structures and installation locations. When the air conditioner is relocated, the second pipeline hole 140 can be adjusted to the new connection position by sliding it again.

[0056] In some embodiments of the pipeline sealing assembly of the present invention, as Figure 6As shown, the length L of the first pipeline hole 130 is greater than twice the width W. The longer the length of the first pipeline hole 130 is, the greater the selection space for the connection position of the pipeline 200 is.

[0057] In some embodiments of the pipeline sealing assembly of the present invention, as Figure 6 As shown, the first pipeline hole 130 extends along the first direction. The second pipeline hole 140 is slidably provided along the first direction.

[0058] In this embodiment, the first pipeline hole 130 can be a linear, elongated hole, with the first direction being the direction of extension of the line. The first direction can be horizontal, vertical, or inclined, as needed. A linear, elongated hole is relatively easy to manufacture. Since the sliding direction of the second pipeline hole 140 is linear, it also facilitates the installation of a sliding stop structure for the baffle 120 on the base plate 110. The sliding stop structure can be a slide groove 150, a guide rail, or the like.

[0059] In some embodiments of the pipeline sealing assembly of the present invention, as Figure 4-5 As shown, a slide groove 150 extending along a first direction is provided on the inner side of the base plate 110 , and the baffle 120 is slidably installed on the inner side of the base plate 110 through the slide groove 150 .

[0060] The inner side of base plate 110 points away from the mounting wall (or cabinet back panel) and toward the interior of the air conditioner. Baffle 120 can be located on either the outside or inside of base plate 110. When located on the outside of base plate 110, baffle 120 is located between base plate 110 and the wall (or cabinet back panel), making it difficult to operate. When baffle 120 is located on the inside of base plate 110, the installer can operate baffle 120 from the front, adjusting the position of second conduit hole 140, resulting in more efficient installation.

[0061] The chute 150 can be connected to the inner side of the base plate 110 by welding, bonding, fasteners, etc. It can also be integrally formed on the inner side of the base plate 110. The chute 150 has a simple structure, reliable connection, and low manufacturing cost.

[0062] In some embodiments of the pipeline sealing assembly of the present invention, as Figure 8 As shown, the first baffle 122 is slidably mounted on the base plate 110 via a sliding groove 150. The second baffle 124 is detachably fixedly connected to the first baffle 122.

[0063] The first baffle 122 and the second baffle 124 can both be slidably connected to the slide groove 150, or one of them can be slidably connected to the slide groove 150 to change the position of the second pipeline hole 140. In this embodiment, the second baffle 124 can be removably fixed to the first baffle 122 through plugging, snapping, fasteners, etc. This arrangement facilitates the installation of the first baffle 122 and the second baffle 124, improving installation efficiency.

[0064] In some embodiments of the pipeline sealing assembly of the present invention, as Figure 5 As shown, the first baffle 122 and the second baffle 124 are both slidably connected to the sliding groove 150 .

[0065] In this embodiment, when the first baffle 122 and the second baffle 124 slide in opposite directions, the second pipeline hole 140 can be opened, facilitating the insertion of the pipeline 200 through the first pipeline hole 130. When the first baffle 122 and the second baffle 124 slide in opposite directions, the second pipeline hole 140 contracts, fitting and wrapping around the outer circumference of the cross section of the pipeline 200.

[0066] In this embodiment, the first baffle 122 and the second baffle 124 can be mirror images, or the first baffle 122 and the second baffle 124 can be the same part, so as to reduce the number of parts and thus reduce manufacturing costs.

[0067] In some embodiments of the pipeline sealing assembly of the present invention, as Figure 9 As shown, the first end 122a of the first baffle 122 away from the second pipeline hole 140 is fixedly arranged, and the second end 122b of the first baffle 122 away from the first end 122a is telescopically arranged along the first direction.

[0068] The third end 124 a of the second baffle 124 away from the second pipeline hole 140 is fixedly disposed, and the fourth end 124 b of the second baffle 124 away from the third end 124 a is telescopically disposed along the first direction.

[0069] In this embodiment, the first baffle 122 and the second baffle 124 have a telescopic structure. The telescopic structure can be a folding structure (such as a folding fan), a pull-out structure (such as a telescopic antenna), or a flexible structure (such as an elastic material), and can be configured as needed.

[0070] When the first baffle 122 and / or the second baffle 124 are integrally slidably connected to the base plate 110, to ensure that the baffle 120 covers the first pipeline hole 130 in all circumstances, the first baffle 122 and / or the second baffle 124 need to have a larger size and area. Furthermore, sufficient accommodation space must be provided on the base plate 110 to ensure that the sliding movement of the first baffle 122 and / or the second baffle 124 is not impeded. In this embodiment, by providing a retractable first baffle 122 and second baffle 124, their size and area can be significantly reduced, and no additional accommodation space is required on the base plate 110.

[0071] In some embodiments of the pipeline sealing assembly of the present invention, as Figure 2 As shown, the first direction is the length direction of the air conditioner.

[0072] In this embodiment, the first conduit hole 130 extends in the longitudinal direction of the air conditioner. If the air conditioner is a vertically mounted cabinet unit, the first direction may extend vertically. If the air conditioner is a horizontally mounted wall unit, the first direction may extend horizontally. When the first direction is aligned with the longitudinal direction of the air conditioner, the length of the first conduit hole 130 can be increased, thereby increasing the choice of connection locations for the conduit 200.

[0073] In some embodiments of the air conditioner of the present invention, as Figure 1 As shown, the air conditioner includes a housing 300 , a pipeline 200 , and a pipeline sealing assembly 100 according to any one of the above embodiments or a combination of the above embodiments. A substrate 110 is disposed on the housing 300 .

[0074] One or more pipeline sealing assemblies 100 may be provided on the air conditioner, and may be provided as needed, for example, one at each end of the air conditioner in the longitudinal direction.

[0075] By providing the pipeline sealing assembly 100 , the air conditioner can be adapted to different building structures and installation locations, and the installation location of the air conditioner can be changed multiple times without replacing the pipeline sealing assembly 100 .

[0076] In some embodiments of the air conditioner of the present invention, the housing 300 forms a substrate 110. The substrate 110 and the housing 300 may be integrally formed, or the substrate 110 may be a partial structure of the housing 300.

[0077] In some embodiments of the air conditioner of the present invention, as Figure 3 As shown, an air duct 400 and a heat exchanger 500 located in the air duct 400 are further provided in the housing 300 .

[0078] The refrigerant pipe of the pipeline 200 passes through the first pipeline hole 130 and the second pipeline hole 140 and is connected to the heat exchanger 500 .

[0079] In some embodiments of the air conditioner of the present invention, as Figure 1-3 As shown, the air conditioner is a built-in air conditioner.

[0080] The air inlet 420 and the air outlet 440 of the air duct 400 are both located at the front side of the air conditioner, and the air inlet 420 is spaced apart and arranged above the air outlet 440. The first pipeline hole 130 is located at the upper side of the air duct 400.

[0081] Embedded air conditioners can be embedded and installed in buildings or furniture cabinets (such as cabinets, TV cabinets, wardrobes, etc.). Because they are covered by buildings or furniture cabinets on all sides, they can usually only be set up as a front-to-front air-outlet structure.

[0082] In this embodiment, the first pipeline hole 130 is located above the air duct 400, effectively utilizing the redundant space at the top of the air conditioner body to arrange the pipeline 200. Furthermore, since the first pipeline hole 130 is located above the air duct 400, components such as the heat exchanger 500 and fan are not located in front of the first pipeline hole 130. The operator can observe the location of the first pipeline hole 130 from the front of the air conditioner, facilitating installation. Furthermore, when installing the pipeline 200, the operator can use the air duct 400 as a work area for bending, fixing, and docking the pipeline 200, further improving installation efficiency.

[0083] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
