Description

Technical Field

[0001] This utility model relates to the field of home appliances, and in particular to an indoor unit of an air conditioner. Background Technology

[0002] A typical residential wall-mounted air conditioner consists of two parts: an indoor unit and an outdoor unit. During installation, the indoor and outdoor units are connected via refrigerant piping to allow refrigerant circulation within the air conditioning system. Additionally, the outdoor unit's power and control cables must be connected to the indoor unit. The indoor unit usually also has a drain pipe to remove condensate. These piping lines are typically encased in insulation material and extend from the indoor unit to the outdoor unit.

[0003] To facilitate flexible wiring adjustments by installers based on the actual installation environment, air conditioner indoor units typically have multiple pre-installed pipe ports on both sides or the bottom of the casing, covered by removable baffles. Installers can selectively remove the baffles at the appropriate locations to access the pipe ports, depending on the on-site wiring requirements. However, when users need to change the installation location of the indoor unit and access other pipe ports, the original pipe ports will be exposed. This not only detracts from the overall aesthetics of the indoor unit but may also lead to dust accumulation and insect intrusion, affecting the normal operation of the equipment. Furthermore, because existing air conditioner indoor units use an integrated casing design, the replacement process is complex and costly, making it difficult for users to effectively seal unused pipe ports by replacing the casing.

[0049] Figure 1 and Figure 6 These are schematic diagrams of an indoor unit 10 of an air conditioner according to an embodiment of the present invention, wherein... Figure 1 The front of the indoor unit 10 of the air conditioner is shown. Figure 6 The rear side of the indoor unit 10 of the air conditioner is shown.

[0050] refer to Figure 1 and Figure 2As shown, this embodiment provides an indoor unit 10 for an air conditioner, which includes a casing 20, a lower trim panel 30, two side trim panels 40, and two end panels 50. Because existing indoor units for air conditioners use an integrated casing design, when users need to use other pipe outlets due to reasons such as changing the installation location of the indoor unit, the existing pipe outlets will be exposed, and it is difficult for users to close the unused pipe outlets by replacing the casing.

[0051] To overcome this problem, this embodiment specifically provides a lower trim panel 30 and two end panels 50 on the outer side of the casing 20 of the indoor unit 10 of the air conditioner. The casing 20 includes a bottom plate 22 at the bottom and two side panels 24 on the lateral sides. The lower trim panel 30 is detachably disposed below the bottom plate 22, and the two side panels 40 are detachably disposed on the outer side of each side panel 24. (Reference) Figure 3 and Figure 4 As shown, the lower trim panel 30 includes a first plate 32 having a first pipe opening formed on its rear side, and a pipe opening baffle 34 disposed at the first pipe opening to cover the first pipe opening. Each side trim panel 40 includes a second plate 42 having a second pipe opening formed on its rear side, and a pipe opening baffle 44 disposed at the second pipe opening to cover the second pipe opening.

[0052] When a user installs the indoor unit 10 of the air conditioner and needs to enable a pipeline port, the user can remove the pipeline port baffle 34 on the lower trim panel 30 or the pipeline port baffle 44 on one of the side trim panels 40, depending on the actual installation environment. This allows pipelines, including refrigerant pipes, drain pipes, and the connection lines of the outdoor unit of the air conditioner, to be connected to the indoor unit 10 from below through the first pipeline port on the lower trim panel 30, or from the side through the second pipeline port on the side trim panel 40. Since the lower trim panel 30 and the two side trim panels 40 in this embodiment are all detachable from the casing 20, when the user needs to enable other pipeline ports due to reasons such as changing the installation position of the indoor unit 10, the unused pipeline ports can be closed by replacing only one lower trim panel 30 or side trim panel 40, without having to replace the entire casing 20.

[0053] refer to Figure 6 and Figure 7 As shown, in this embodiment, the bottom plate 22 of the casing 20 forms a clearance opening directly opposite the first pipeline inlet, and the two side plates 24 each form a clearance opening directly opposite the second pipeline inlet. The pipeline can pass through the casing 20 and connect to the indoor unit 10 of the air conditioner through the clearance openings.

[0054] In some alternative implementations, refer to Figure 3As shown, the pipe inlet baffle 34 of the lower trim panel 30 forms a first arc-shaped rib 342 on its upper surface where it connects with the first panel 32. When the user needs to access the first pipe inlet on the lower trim panel 30, the pipe inlet baffle 34 can be cut off along the first arc-shaped rib 342 on the upper surface of the lower trim panel 30. Since the lower trim panel 30 in this embodiment is detachable from the housing 20, the user can first remove the lower trim panel 30 from the indoor unit 10 of the air conditioner, and then remove the pipe inlet baffle 34 to reduce the difficulty of operation.

[0055] In some alternative embodiments, a second arcuate rib 344 is formed on the upper surface of the middle portion of the pipe inlet baffle 34 of the lower trim panel 30. The second arcuate rib 344 is located inside the first arcuate rib 342 and defines a small area. If the user cuts along the second arcuate rib 344 on the upper surface of the lower trim panel 30, only a small portion of the first pipe inlet will be exposed. This design facilitates the user passing the pipe connecting the outdoor unit of the air conditioner and the indoor unit power cord through two different pipe inlets, respectively, and reduces the exposed area of ​​the pipe inlet through which the smaller diameter indoor unit power cord passes.

[0056] Similar to the design of the pipe inlet baffle 34 on the lower trim panel 30, in some optional embodiments, the pipe inlet baffle 44 of each side trim panel 40 forms a first arcuate rib 442 on the inner surface where it contacts the second panel 42. Simultaneously, in some optional embodiments, the inner surface of the middle portion of the pipe inlet baffle 44 of each side trim panel 40 forms a second arcuate rib 444. It can be understood that the inner surface of the side trim panel 40 described in this embodiment refers to the surface facing the side panel 24 of the housing 20, while the outer surface refers to the surface facing the outer side of the indoor unit 10 of the air conditioner.

[0057] The protrusion height of the first arc-shaped ribs 342, 442 and the second arc-shaped ribs 344, 444 on the lower trim panel 30 and the side trim panel 40 can usually be designed to be 1.5-2mm, and their thickness can usually be designed to be 0.5-1mm.

[0058] To reduce the difficulty of disassembling the pipe opening baffle 34, in some optional embodiments, the thickness of the pipe opening baffle 34 of the lower trim panel 30 at the junction with the first panel 32 can be less than that of the first panel 32, thereby reducing the difficulty of cutting the pipe opening baffle 34. Similarly, the thickness of the pipe opening baffle 44 of each side trim panel 40 at the junction with the second panel 42 can also be less than that of the second panel 42.

[0059] To make the surface of the indoor unit 10 of the air conditioner more concise and aesthetically pleasing, in some optional embodiments, the lower surface of the pipe inlet baffle 34 of the lower trim panel 30 at the junction with the first plate 32 is a smooth plane. In other words, in this embodiment, there is no gap formed by the point-discontinuous connection at the junction of the pipe inlet baffle 34 and the first plate 32 of the lower trim panel 30, so the position of the first pipe inlet on the lower trim panel 30 cannot be seen from the appearance.

[0060] Similarly, in some alternative embodiments, the outer surface of the pipe port baffle 44 of each side panel 40 where it meets the second panel 42 is a smooth plane, so the position of the second pipe port on the side panel 40 is not visible from the outside.

[0061] In some alternative implementations, refer to Figure 3 and Figure 7 As shown, at least one first fastener 322 and at least one first hook 324 are formed on the upper surface of the lower trim panel 30; and the bottom plate 22 forms a first fixing hole at the position opposite each first fastener 322 and a first locking hole at the position opposite each first hook 324.

[0062] Each first fastener 322 in this embodiment has a protrusion protruding to its side and is configured to engage with the lateral side of the first fastening hole when inserted into it, thereby engaging and fixing the lower trim panel 30 relative to the bottom plate 22 in the longitudinal direction and preventing the lower trim panel 30 from falling off.

[0063] Each first hook 324 extends rearward and into a first hook hole, thereby both restricting the lower trim panel 30 from moving further rearward relative to the base plate 22 after the lower trim panel 30 is installed in place relative to the base plate 22, and preventing the lower trim panel 30 from falling off.

[0064] In some alternative embodiments, each first fastener 322 may be disposed near the front side of the lower trim panel 30, while each first hook 324 may be disposed near the rear side of the lower trim panel 30. When the user needs to remove the lower trim panel 30, the user can pull the lower trim panel 30 downward from the front to disengage each first fastener 322 near the front from the first fastening hole, and then pull the lower trim panel 30 forward and downward to disengage each first hook 324 from the first locking hole. When the user needs to install the lower trim panel 30, the user can first align the first hook 324 with the first locking hole and push the lower trim panel 30 upward and backward. After the first hook 324 abuts against the first locking hole, the user can push the lower trim panel 30 upward until the first hook 324 engages with the first locking hole to complete the installation.

[0065] In some alternative embodiments, each first hook 324 extends obliquely upward and rearward, forming an opening that gradually increases from front to back between the lower trim panel 30 and the upper surface of the lower trim panel 30, thereby facilitating the installation of the lower trim panel 30 at a larger angle and aligning the first hook 324 with the first latch hole.

[0066] In some alternative embodiments, each first fastener 322 abuts against at least one lateral side of the first fastening hole, and the upper and lower sides of the protrusion are both inclined surfaces.

[0067] The lateral side of the first fixing hole refers to the left or right side of the first fixing hole. In this embodiment, each first fixing member 322 abuts against at least one lateral side of the first fixing hole, thus preventing the lower trim panel 30 from moving laterally relative to the base plate 22 of the housing 20. Multiple first fixing members 322 are typically distributed laterally on the lower trim panel 30, with at least two first fixing members 322 usually designed to abut against two opposite sides of the corresponding first fixing hole; that is, one first fixing member 322 abuts against the left side of the first fixing hole, and the other first fixing member 322 abuts against the right side of the first fixing hole. The upper and lower sides of the protrusion are inclined surfaces, which can guide the removal or installation of the lower trim panel 30, reducing the difficulty of removing and installing the lower trim panel 30 and preventing damage or breakage of the first fixing members 322.

[0068] It should be noted that the "ambush" in this embodiment does not limit the first fixing member 322 to a tight fit with the side of the first fixing hole, but rather means that the two can be either tightly fitted or form an assembly gap of less than or equal to 0.5 mm. Typically, considering factors such as production errors or deformation during daily use, this assembly gap can be designed to be 0.2 mm, but the actual measured value is often greater or less than this value. The abutment in other embodiments of this utility model is similar to that in this embodiment, and therefore will not be described again.

[0069] Figure 8 This is a partially enlarged schematic diagram of the base plate 22 of the housing 20 at the clearance opening, and also shows two first locking holes located on both sides of the clearance opening. (Reference) Figure 8 As shown, in some optional embodiments, the first locking hole is funnel-shaped, with its width decreasing from front to back. In this embodiment, the funnel-shaped first locking hole can guide the first hook 324 to align with the first locking hole, thereby reducing the difficulty of installing the lower trim panel 30.

[0070] from Figure 8As can be seen, the funnel shape described in this embodiment does not refer to the overall width of the first card hole gradually decreasing from front to back, but rather to a part of the first card hole having a decreasing width from front to back. To facilitate guiding the first hook 324 to align with the first card hole, the part of the first card hole with a decreasing width from front to back is usually close to the rear side of the first card hole, so that the front part of the first card hole has a larger area and width.

[0071] Referring to Figure 3 and Figure 7 As shown, in some alternative embodiments, at least one first limiting member 328 is further formed on the upper surface of the lower trim panel 30, and each first limiting member 328 is configured to extend into a first fixing hole and abut against the front side edge of the first fixing hole.

[0072] Since the first fixing member 322 can only prevent the lateral movement of the lower trim panel 30, at least one first limiting member 328 is additionally formed on the upper surface of the lower trim panel 30 in this embodiment. The first limiting member 328 is disposed close to the first fixing member 322 and extends into the first fixing hole together with the first fixing member 322, and abuts against the front side edge of the first fixing hole, thereby preventing the lower trim panel 30 from moving forward and cooperating with the first hook 324 to prevent the lower trim panel 30 from moving back and forth.

[0073] In some alternative embodiments, at least one first positioning member 326 is further formed on the upper surface of the lower trim panel 30; and a first positioning hole is formed on the bottom plate 22 at a position opposite to each first positioning member 326. Each first positioning member 326 abuts against at least one side edge of the first positioning hole.

[0074] In this embodiment, the first positioning holes on the bottom plate 22 of the housing 20 are longitudinally opened, and thus have left and right side edges as well as front and back side edges. The first positioning member 326 abuts against at least one side edge of the first positioning hole, thereby preventing the lower trim panel 30 from moving relative to the housing 20 in at least one direction.

[0075] The cross-sectional shape of the first positioning member 326 can be in the shape of "I", "king", or "square" to increase the contact area with the first positioning hole. Of course, the first positioning member 326 can also be of other shapes, and the multiple first positioning members 326 in this embodiment are not limited to the same shape, and are not limited herein.

[0076] Referring to Figure 4 As shown, in some alternative embodiments, a plurality of second hooks 422 are formed on the inner surface of each side trim panel 40; and a second card hole is formed on the side plate 24 at a position opposite to each second hook 422. Each second hook 422 extends inward and into a second card hole. The side trim panel 40 is detachably fixed to the side plate 24 of the housing 20 by clamping and fixing of the plurality of second hooks 422 and the second card holes.

[0077] In some optional embodiments, at least two second hooks 422 are formed at the lower side edge of the side trim panel 40 at intervals in the front and rear directions. The two second hooks 422 located on the lower side edge of the side trim panel 40 and arranged at intervals in the front and rear directions can better support and fix the side trim panel 40, and prevent the side trim panel 40 from shaking relative to the side plate 24 of the housing 20.

[0078] In some optional embodiments, the end of the second hook 422 on the lower side edge of the side trim panel 40 protrudes downward to be clamped and fixed with the lower side edge of the second hole. And at least one second hook 422 with an upward protruding end and higher than each second hook 422 on the lower side edge of the side trim panel 40 is further formed on the inner surface of the side trim panel 40.

[0079] The protruding end of the second hook 422 is the claw structure clamped inside the side plate 24. In this embodiment, the protruding directions of the two second hooks 422 on the lower side edge of the side trim panel 40 and the second hook 422 higher than it are opposite, forming a design of reverse buckling, so that the side trim panel 40 is fixed more firmly relative to the side plate 24 of the housing 20.

[0080] In some optional embodiments, at least one second positioning member 424 is further formed on the inner surface of the side trim panel 40; and a second positioning hole is formed on the side plate 24 at a position opposite to each second positioning member 424. Each second positioning member 424 abuts against at least one side edge of the second positioning hole.

[0081] The shape setting and function of the second positioning member 424 on the side trim panel 40 are similar to those of the first positioning member 326 on the lower trim panel 30, and are used to prevent the side trim panel 40 from moving relative to the housing 20 in at least one direction in the front-back direction and the up-down direction. The cross-sectional shape of the second positioning member 424 can also be in the shape of "I", "king", or "mouth" to increase the contact area with the second positioning hole. Of course, the second positioning member 424 can also be in other shapes, and the multiple second positioning members 424 in this embodiment are not limited to the same shape, which is not limited here.

[0082] An air outlet facing the front lower direction is usually formed at the lower front side of the housing 20. Since the lateral width of the air outlet is often narrower than the overall width of the housing 20, the bottom plate 22 of the housing 20 extends to the lateral two ends of the air outlet. In order to cover the bottom plate 22 at the lateral two ends of the air outlet and make the appearance of the air conditioner indoor unit 10 more unified, referring to Figure 2 as shown, the air conditioner indoor unit 10 of this embodiment further includes two end plates 50.

[0083] In this embodiment, the lower trim panel 30 is entirely located behind the air outlet, and the two lateral ends of the lower trim panel 30 are flush with the two lateral ends of the air outlet in the front-to-back direction. The two end plates 50 are detachably disposed below the base plate 22 and extend from the lateral front end of the air outlet to the lateral rear end of the lower trim panel 30, respectively.

[0084] Because the indoor unit 10 of the air conditioner has a large lateral width, if the lower trim panel 30 and the two end panels 50 are designed as a single structure, the disassembly of the whole unit would be difficult due to the fact that the two end panels 50 extend forward relative to the two ends of the lower trim panel 30. In order to facilitate the individual disassembly of the lower trim panel 30 and avoid deformation or damage to the whole unit due to disassembly, this embodiment specifically adopts a separate design for the two end panels 50 and the lower trim panel 30.

[0085] In some alternative embodiments, at least one third fastener 52 and at least one third hook 54 are formed on the upper surface of each end plate 50; and the bottom plate 22 forms a third fastening hole at the position opposite each third fastener 52 and a third locking hole at the position opposite each third hook 54.

[0086] Each third fastener 52 has a protrusion that protrudes to its side and is configured to engage with the lateral side of a third fastening hole when inserted into it, thereby engaging and securing the end plate 50 relative to the base plate 22 in the longitudinal direction and preventing the end plate 50 from falling off.

[0087] Each third hook 54 extends rearward and into a third locking hole, thereby both restricting the end plate 50 from moving further rearward relative to the base plate 22 after the end plate 50 is installed in place relative to the base plate 22, and preventing the end plate 50 from falling off.

[0088] In some alternative embodiments, the lower surface of the protrusion of the third fastener 52 can be flat and fit tightly against the edge of the third fastening hole to better secure the end plate 50.

[0089] In some alternative implementations, similar to the first locking hole, the third locking hole may also be funnel-shaped with a decreasing width from front to back and guide the third locking hook 54 to align with the first locking hole, thereby reducing the difficulty of installing the end plate 50.

[0090] Specifically, the third fixing hole and the third locking hole in this embodiment, as well as the "holes" described in other embodiments of this utility model, are not limited in shape to be round or square holes, or even to holes with closed sides. In other words, the shape of the "holes" described in the various embodiments of this utility model is not limited, and they can be located at the edge of the bottom plate 22 or the side plate 24 of the housing 20 and do not have closed sides.

[0091] In some optional embodiments, at least one third positioning member 56 is further formed on the upper surface of each end plate 50; and a third positioning hole is formed in the bottom plate 22 at a position opposite to each third positioning member 56. Each third positioning member 56 abuts against at least one side of the third positioning hole.

[0092] The shape and function of the third positioning member 56 on the end plate 50 are similar to those of the first positioning member 326 on the lower trim panel 30, and are used to prevent the end plate 50 from moving relative to the housing 20 in at least one direction in the front-rear direction and the lateral direction. The cross-sectional shape of the third positioning member 56 can also be in the shape of a "work" character, a "king" character or a "mouth" character to increase the abutting area with the third positioning hole. Of course, the third positioning member 56 can also be of other shapes, and the multiple third positioning members 56 in this embodiment are not limited to the same shape, which is not limited herein.

[0093] 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 that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
