Description

TECHNICAL FIELD

[0001] The utility model relates to the field of home appliances, in particular to an indoor unit of an air conditioner. BACKGROUND

[0002] A household wall-mounted air conditioner usually consists of an indoor unit and an outdoor unit. During installation, the indoor unit and the outdoor unit need to be connected by a refrigerant pipeline to realize the circulation of refrigerant in the air conditioning system. In addition, the power supply line and control line of the outdoor unit also need to be connected to the indoor unit. The indoor unit is usually also equipped with a drain pipe for draining condensed water. These pipelines are usually wrapped together with thermal insulation materials and extend from the indoor unit to the outdoor unit.

[0003] In order to facilitate the installation personnel to flexibly adjust the wiring scheme according to the actual installation environment, the indoor unit of the air conditioner usually has multiple pipeline ports pre-set on both sides or the bottom of the shell, and is equipped with detachable baffles for shielding. The installation personnel can selectively remove the baffles at the corresponding positions to enable the pipeline ports according to the on-site wiring requirements. However, when the user needs to change the installation position of the indoor unit and enable other pipeline ports, the original pipeline ports will be exposed, which not only destroys the overall aesthetics of the indoor unit, but also may cause dust accumulation and insect intrusion, affecting the normal operation of the equipment. In addition, since the existing indoor unit of the air conditioner adopts an integrated shell design, the replacement process is complex and costly, and the user cannot effectively close the idle pipeline ports by replacing the shell.

[0047] Figure 1 And Figure 6 Fig. 1 and Fig. 2 respectively show a schematic diagram of an air conditioner indoor unit 10 according to an embodiment of the utility model, wherein Figure 1 Fig. 1 shows the front side of the air conditioner indoor unit 10, Figure 6 Fig. 2 shows the rear side of the air conditioner indoor unit 10.

[0048] Referring to Figure 1 And Figure 2 As shown in Fig. 1 and Fig. 2, the embodiment provides an air conditioner indoor unit 10, which comprises a casing 20, a lower trim plate 30, two side trim plates 40 and two end plates 50. Since the existing air conditioner indoor unit adopts an integrated casing design, when the user needs to enable other pipeline ports due to changing the installation position of the indoor unit and other reasons, the original pipeline port that has been enabled will be in an exposed state, and the user is difficult to close the idle pipeline port by replacing the casing.

[0049] In order to overcome this problem, the embodiment particularly provides the lower trim plate 30 and the two end plates 50 outside the casing 20 of the air conditioner indoor unit 10, wherein the casing 20 comprises a bottom plate 22 located at the bottom and two side plates 24 located at the two lateral sides, the lower trim plate 30 is detachably arranged below the bottom plate 22, and the two side trim plates 40 are respectively detachably arranged outside one side plate 24. Referring to Figure 3 And Figure 4As shown, the lower trim panel 30 includes a first panel body 32 formed with a first line port on the rear side edge, and a line port baffle 34 arranged at the first line port to shield the first line port. Each side trim panel 40 includes a second panel body 42 formed with a second line port on the rear side edge, and a line port baffle 44 arranged at the second line port to shield the second line port.

[0050] When the user installs the air conditioner indoor unit 10 and needs to enable a line port, the user can remove the line port baffle 34 on the lower trim panel 30 or the line port baffle 44 on one of the side trim panels 40 according to the actual installation environment, so that the line including the refrigerant pipe, the drain pipe, and the connection line of the air conditioner outdoor unit can be accessed to the air conditioner indoor unit 10 from below through the first line port on the lower trim panel 30, or from the side through the second line port on the side trim panel 40. Since the lower trim panel 30 and the two side trim panels 40 of the present embodiment are detachable relative to the cabinet 20, when the user needs to enable other line ports for reasons such as changing the installation position of the air conditioner indoor unit 10, the idle line ports can be closed by replacing only one lower trim panel 30 or side trim panel 40, without replacing the entire cabinet 20.

[0051] Reference is made to Figure 6 and Figure 7 As shown, the bottom plate 22 of the cabinet 20 of the present embodiment forms an avoiding opening at a position opposite to the first line port, and the two side plates 24 each form an avoiding opening at a position opposite to the second line port. The line can pass through the avoiding openings of the cabinet 20 and be accessed to the air conditioner indoor unit 10.

[0052] In some alternative embodiments, as shown in Figure 3 The line port baffle 34 of the lower trim panel 30 forms a first arc-shaped rib 342 on the upper surface at the joint with the first panel body 32. When the user needs to enable the first line port on the lower trim panel 30, the line port baffle 34 can be cut along the first arc-shaped rib 342 on the upper surface of the lower trim panel 30. Since the lower trim panel 30 of the present embodiment is detachable relative to the cabinet 20, the user can first detach the lower trim panel 30 from the air conditioner indoor unit 10, and then remove the line port baffle 34, to reduce the operation difficulty.

[0053] In some alternative embodiments, the upper surface of the middle part of the line port baffle 34 of the lower trim panel 30 further forms a second arc-shaped rib 344. The second arc-shaped rib 344 is located inside the first arc-shaped rib 342 and defines a small range area. If the user cuts along the second arc-shaped rib 344 on the upper surface of the lower trim panel 30, only a small part of the first line port will be exposed. This design is to facilitate the user to pass the line connecting the air conditioner outdoor unit and the indoor unit power line through the line port from two different positions, and to reduce the exposure area of the line port through which the indoor unit power line with smaller diameter passes.

[0054] Similar to the design at the pipeline port baffle 34 on the lower panel 30, in some alternative embodiments, the inner surface of the pipeline port baffle 44 of each side panel 40 forms a first arc-shaped rib 442 at the interface with the second panel body 42. Meanwhile, in some alternative embodiments, the inner surface of the middle portion of the pipeline port baffle 44 of each side panel 40 forms a second arc-shaped rib 444. It is understood that the inner surface of the side panel 40 described in the present embodiment refers to the surface facing the side panel 24 of the casing 20, and correspondingly, the outer surface refers to the surface facing the outside of the air conditioner indoor unit 10.

[0055] The protruding height of each of the first arc-shaped rib 342, 442 and the second arc-shaped rib 344, 444 on the lower panel 30 and the side panel 40 can be designed as 1.5-2 mm, and the thickness thereof can be designed as 0.5-1 mm.

[0056] In order to reduce the difficulty of dismounting the pipeline port baffle 34, in some alternative embodiments, the thickness of the pipeline port baffle 34 of the lower panel 30 at the interface with the first panel body 32 can be less than that of the first panel body 32, so as to reduce the difficulty of cutting the pipeline port baffle 34. Similarly, the thickness of the pipeline port baffle 44 of each side panel 40 at the interface with the second panel body 42 can also be less than that of the second panel body 42.

[0057] In order to make the surface of the air conditioner indoor unit 10 more simple and beautiful, in some alternative embodiments, the lower surface of the pipeline port baffle 34 of the lower panel 30 at the interface with the first panel body 32 is a smooth plane. In other words, in the present embodiment, there is no gap formed by point-to-point connection at the interface between the pipeline port baffle 34 and the first panel body 32 of the lower panel 30, so that the position of the first pipeline port on the lower panel 30 cannot be seen from the appearance.

[0058] Similarly, in some alternative embodiments, the outer surface of the pipeline port baffle 44 of each side panel 40 at the interface with the second panel body 42 is a smooth plane, so that the position of the second pipeline port on the side panel 40 cannot be seen from the appearance.

[0059] In some alternative embodiments, referring to Figs. 2 and 3, the upper surface of the lower panel 30 forms at least one first fixing member 322 and at least one first clamping hook 324; and the bottom plate 22 forms a first fixing hole at the position opposite to each first fixing member 322 and a first clamping hole at the position opposite to each first clamping hook 324. Figure 3 Figure 7 In some alternative embodiments, referring to Figs. 2 and 3, the upper surface of the lower panel 30 forms at least one first fixing member 322 and at least one first clamping hook 324; and the bottom plate 22 forms a first fixing hole at the position opposite to each first fixing member 322 and a first clamping hole at the position opposite to each first clamping hook 324.

[0060] ​Each first fixing member 322 in the embodiment has a protruding portion protruding to the side of itself, and is configured to be clamped and fixed with the lateral side of the first fixing hole when extending into the first fixing hole, thereby clamping 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.

[0061] Each first clamping hook 324 extends rearward and extends into a first clamping hole, thereby limiting the further rearward movement of the lower trim panel 30 relative to the bottom plate 22 and preventing the lower trim panel 30 from falling off after the lower trim panel 30 is installed in place relative to the bottom plate 22.

[0062] In some optional embodiments, each first fixing member 322 can be arranged near the front side of the lower trim panel 30, and each first clamping hook 324 can be arranged near the rear side of the lower trim panel 30. When a user needs to disassemble the lower trim panel 30, the lower trim panel 30 can be pulled downward from the front side to make each first fixing member 322 near the front side disengage from the first fixing hole, and then the lower trim panel 30 can be pulled forward and downward to make each first clamping hook 324 disengage from the first clamping hole. When a user needs to assemble the lower trim panel 30, the first clamping hook 324 can be aligned with the first clamping hole first, and then the lower trim panel 30 can be pushed rearward and upward until the first clamping hook 324 engages with the first clamping hole.

[0063] In some optional embodiments, each first clamping hook 324 extends rearward and upward at an inclination, and forms an opening between the upper surface of the lower trim panel 30 and the first clamping hook 324, the opening gradually increases from the front to the rear, thereby facilitating the assembly of the lower trim panel 30 at a large inclination angle and aligning the first clamping hook 324 with the first clamping hole.

[0064] In some optional embodiments, each first fixing member 322 abuts at least one lateral side of the first fixing hole, and the upper side and the lower side of the protruding portion are both inclined surfaces.

[0065] The lateral side of the first fixing hole refers to the left side or the right side of the first fixing hole. Each first fixing member 322 in the embodiment abuts at least one lateral side of the first fixing hole and can prevent the lateral movement of the lower trim panel 30 relative to the bottom plate 22 of the case 20. A plurality of first fixing members 322 are usually distributed on the lower trim panel 30 along the lateral direction, and at least two first fixing members 322 are usually designed to abut two opposite sides of the corresponding first fixing hole, that is, one first fixing member 322 abuts the left side of the first fixing hole, and the other first fixing member 322 abuts the right side of the first fixing hole. The upper side and the lower side of the protruding portion being both inclined surfaces can play a guiding role when disassembling or assembling the lower trim panel 30, thereby reducing the difficulty of disassembling or assembling the lower trim panel 30 and avoiding the damage and breakage of the first fixing member 322.

[0066] 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.

[0067] 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.

[0068] from Figure 8 As can be seen from the text, the funnel shape described in this embodiment does not refer to the width of the first card hole gradually decreasing from front to back, but rather to a portion of the first card hole decreasing in width from front to back. To facilitate guiding the first hook 324 to align with the first card hole, the portion of the first card hole that decreases in width from front to back is usually located near the rear side of the first card hole, so that the front part of the first card hole has a larger area and width.

[0069] refer to Figure 3 and Figure 7 As shown, in some alternative embodiments, at least one first limiting member 328 is also formed on the upper surface of the lower trim panel 30, each first limiting member 328 being configured to extend into a first fixing hole and abut against the front side of the first fixing hole.

[0070] Since the first fixing member 322 can only prevent the lower trim panel 30 from moving laterally, this embodiment also forms at least one first limiting member 328 on the upper surface of the lower trim panel 30. 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 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.

[0071] In some alternative embodiments, at least one first positioning element 326 is also formed on the upper surface of the lower trim panel 30; and the base plate 22 forms a first positioning hole at a position opposite to each first positioning element 326. Each first positioning element 326 abuts against at least one side of the first positioning hole.

[0072] In this embodiment, the first positioning holes on the bottom plate 22 of the housing 20 are arranged longitudinally, so they have left and right sides as well as front and back sides. The first positioning member 326 abuts against at least one side of the first positioning hole, thereby preventing the lower decorative plate 30 from moving relative to the housing 20 in at least one direction.

[0073] 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, which is not defined here.

[0074] Reference Figure 4 As shown, in some optional embodiments, a plurality of second hooks 422 are formed on the inner surface of each side decorative plate 40; and a second hole is formed in the side plate 24 at a position facing each second hook 422. Each second hook 422 extends inward and extends into a second hole. By engaging and fixing the plurality of second hooks 422 with the second holes, the side decorative plate 40 is detachably fixed to the side plate 24 of the housing 20.

[0075] In some optional embodiments, at least two second hooks 422 are formed at intervals in the front and back on the lower side of the side decorative plate 40. The two second hooks 422 located on the lower side of the side decorative plate 40 and arranged at intervals in the front and back can better support and fix the side decorative plate 40, and prevent the side decorative plate 40 from shaking relative to the side plate 24 of the housing 20.

[0076] In some optional embodiments, the end of the second hook 422 on the lower side of the side decorative plate 40 protrudes downward to be engaged and fixed with the lower side of the second hole. And at least one second hook 422 is further formed on the inner surface of the side decorative plate 40, the end of which protrudes upward and is higher than each second hook 422 on the lower side of the side decorative plate 40.

[0077] The protruding end of the second hook 422 is the claw structure that is engaged inside the side plate 24. In this embodiment, the protruding directions of the ends of the two second hooks 422 on the lower side of the side decorative plate 40 and the second hook 422 higher than it are opposite, forming a reverse buckling design, so that the side decorative plate 40 is fixed more firmly relative to the side plate 24 of the housing 20.

[0078] In some optional embodiments, at least one second positioning member 424 is further formed on the inner surface of the side decorative plate 40; and a second positioning hole is formed in the side plate 24 at a position facing each second positioning member 424. Each second positioning member 424 abuts against at least one side of the second positioning hole.

[0079] The shape 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 casing 20 in at least one of 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 a "work" character, a "king" character, or a "mouth" character to increase the contact area with the second positioning hole. Of course, the second positioning member 424 can also be of other shapes, and the multiple second positioning members 424 in this embodiment are not limited to the same shape, which is not defined here.

[0080] An air outlet facing the front lower side is usually provided at the lower front side of the casing 20. Since the lateral width of the air outlet is often narrower than the overall width of the casing 20, the bottom plate 22 of the casing 20 extends to the lateral two ends of the air outlet. In order to cover the bottom plates 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.

[0081] In this embodiment, the lower trim panel 30 is entirely located at the rear side of the air outlet, and the lateral two ends of the lower trim panel 30 are flush with the lateral two ends of the air outlet in the front-back direction. The two end plates 50 are detachably arranged below the bottom plate 22 and respectively extend from the front lateral end of the air outlet to the rear lateral end of the lower trim panel 30.

[0082] Since the air conditioner indoor unit 10 has a relatively large lateral width, if the lower trim panel 30 and the two end plates 50 are designed as an integral structure, since the two end plates 50 further extend forward relative to the two ends of the lower trim panel 30, the overall disassembly difficulty is relatively large. In order to facilitate the separate disassembly of the lower trim panel 30 and avoid deformation and damage of the whole due to disassembly, in this embodiment, the two end plates 50 and the lower trim panel 30 are particularly designed in a split structure.

[0083] In some optional embodiments, at least one third fixing member 52 and at least one third hook 54 are formed on the upper surface of each end plate 50; and a third fixing hole is formed on the bottom plate 22 at a position corresponding to each third fixing member 52, and a third engaging hole is formed at a position corresponding to each third hook 54.

[0084] Each third fixing member 52 has a protruding portion protruding towards its side, and is configured to be snap-fixed to the lateral side of the third fixing hole when inserted into a third fixing hole, so as to snap-fix the end plate 50 relative to the bottom plate 22 in the longitudinal direction and prevent the end plate 50 from falling off.

[0085] Each third hook 54 extends backward and is inserted into a third engaging hole, so as to limit the further backward movement of the end plate 50 relative to the bottom plate 22 and prevent the end plate 50 from falling off after the end plate 50 is installed in place relative to the bottom plate 22.

[0086] In some alternative embodiments, the lower surface of the protrusion of the third fixing member 52 may be a flat surface and fit tightly against the edge of the third fixing hole, so as to better fix the end plate 50.

[0087] In some alternative embodiments, similar to the first locking hole, the third locking hole may also be in the shape of a funnel 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 installation difficulty of the end plate 50.

[0088] Specifically, the third fixing hole and the third locking hole in this embodiment, as well as the "holes" described in other embodiments of the present invention, are not limited in shape to round holes or square holes, and are not even limited to holes with closed sides. In other words, the shape of the "holes" described in each embodiment of the present invention is not limited, and can be located at the edge of the bottom plate 22 or the side plate 24 of the casing 20 and do not have closed sides.

[0089] In some alternative embodiments, at least one third positioning member 56 is further formed on the upper surface of each end plate 50; and the bottom plate 22 forms a third positioning hole 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.

[0090] 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 casing 20 in at least one of the front-back direction and the lateral direction. The cross-sectional shape of the third positioning member 56 can also be in the shape of a "worker" character, a "king" character or a "square" character to increase the contact 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.

[0091] 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.
