After the first connector is connected to the water collection tray, the gap between the return air grille and the panel is smaller.

Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an indoor unit and a ceiling-mounted unit. Background Technology

[0002] As an important branch of split-type air conditioners, ceiling-mounted units break the traditional limitations of wall-mounted units ("can only be wall-mounted") and floor-standing units ("can only be floor-standing"). They can be flexibly installed in either the ceiling or the floor, depending on the space layout and decoration requirements. For irregularly shaped spaces (such as sloping roof rooms or loft mezzanines), large-span spaces (such as open-plan living rooms and dining rooms), or scenarios with high requirements for decoration style (such as minimalist or industrial styles), their flexible installation method can better integrate into the overall design and avoid the damage to the aesthetics of decoration caused by traditional air conditioners.

[0003] Since the indoor unit of a ceiling-mounted air conditioner typically connects the return air grille to the panel and chassis to fix the return air grille, and a snap-fit ​​connection is used between the return air grille and the panel to ensure the removability of the return air grille, the return air grille and the panel are prone to loosening after assembly, resulting in a large assembly gap and affecting the product's aesthetics. Utility Model Content

[0004] The main objective of this utility model embodiment is to provide an indoor unit and a ceiling-mounted unit, aiming to improve the technical problem of large assembly gap between the indoor unit return air grille and the panel in the prior art of ceiling-mounted units.

[0005] An embodiment of this utility model provides an indoor unit, comprising:

[0006] panel;

[0007] Return air grille;

[0008] The chassis, the panel, the return air grille, and the chassis are connected in sequence;

[0009] A water tray is provided at the bottom of the panel and connected thereto;

[0010] The return air grille has a first connector at one end connected to the panel, and the first connector passes through the panel and connects to the water receiving tray.

[0011] In some embodiments of this utility model, the panel has a first folded edge at one end near the return air grille, and the water receiving tray has a second folded edge at one end near the return air grille. The second folded edge is located on the side of the first folded edge away from the return air grille. The first connector passes through the first folded edge and connects to the second folded edge, so that the return air grille abuts against the first folded edge.

[0012] In some embodiments of this utility model, a first through hole is provided on the first folded edge, and a second through hole is provided on the second folded edge, which is aligned with the first folded edge. The first connector passes through the first through hole and the second through hole in sequence and is connected to the second folded edge.

[0013] In some embodiments of this utility model, the first connector is configured to change from a first form to a second form under the action of an external force and return to the first form after the external force is removed. The first connector can pass through the first through hole and the second through hole in the first form, and return to the first form and lock with the second through hole after passing through the second through hole.

[0014] In some embodiments of this utility model, the first connector includes a first pin portion and a first spring-loaded latch portion. The first pin portion and the first spring-loaded latch portion are parallel to each other and spaced apart. When the first connector is in the first form, the first pin portion and the first spring-loaded latch portion are parallel to each other. When the first connector is in the second form, the first pin portion and the first spring-loaded latch portion are offset from each other to abut against each other. When the first connector is locked and connected to the second through hole in the first form, the first pin portion abuts against one side of the second through hole, and the first spring-loaded latch portion is fastened to one side of the second through hole.

[0015] In some embodiments of this utility model, a third through hole is provided on the first folded edge, the third through hole and the first through hole are offset along the height direction of the first folded edge, and a fourth through hole is provided on the second folded edge, which is aligned with the third through hole;

[0016] The return air grille is also provided with a second connector, which is sequentially inserted into the third through hole and the fourth through hole.

[0017] In some embodiments of this utility model, a plurality of first through holes and a plurality of third through holes are provided on the first folded edge, and a first through hole is provided between every two adjacent third through holes;

[0018] Alternatively, a third through hole may be provided between every two adjacent first through holes.

[0019] In some embodiments of this utility model, a third connector is provided at the end of the return air grille away from the panel, as the first connector is connected to the water receiving tray and the third connector is connected to the chassis.

[0020] In some embodiments of this utility model, the chassis includes a side plate and a bottom plate connected in sequence, the side plate and the bottom plate are perpendicular to each other, the end of the side plate away from the bottom plate is connected to the return air grille, and the bottom plate is parallel to the return air grille and the panel.

[0021] In some embodiments of this utility model, a ceiling-mounted unit is also provided, which includes the aforementioned indoor unit.

[0022] An embodiment of this utility model provides an indoor unit and a ceiling-mounted unit. The indoor unit connects to the water tray by setting a first connector on the return air grille, which passes through the panel. That is, by connecting the return air grille to the water tray on the inner side of the panel, it is equivalent to moving the connection between the return air grille and the end of the panel to a more inner part of the panel, thereby reducing the distance between the return air grille and the panel. After the first connector is connected to the water tray, the gap between the return air grille and the panel is smaller. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] like Figures 1-8 As shown, this utility model provides an indoor unit 10, including a panel 100, a return air grille 200, a chassis 300, and a water tray 400. The panel 100, the return air grille 200, and the chassis 300 are connected in sequence. The water tray 400 is disposed at the bottom of the panel 100 and connected thereto. The end of the return air grille 200 connected to the panel 100 has a first connector 210, which passes through the panel 100 and connects to the water tray 400.

[0038] It should be noted that the return air grille 200 is located on one side of the panel 100. When the first connector 210 passes through the panel 100 and connects to the water tray 400, compared to the first connector 210 of the return air grille 200 being directly connected to the end of the panel 100 (the end closest to the return air grille 200), the connection position is moved to the inside of the panel 100, thereby making the return air grille 200 fit more tightly against the panel 100, thus reducing the gap between the return air grille 200 and the panel 100.

[0039] It is understood that the indoor unit 10 of this utility model connects the return air grille 200 to the water tray 400 by setting a first connector 210 through the panel 100. That is, by connecting the return air grille 200 to the water tray 400 on the inner side of the panel 100, it is equivalent to moving the connection between the end of the return air grille 200 and the panel 100 to a more inner part of the panel 100, thereby reducing the distance between the return air grille 200 and the panel 100. After the first connector 210 is connected to the water tray 400, the gap between the return air grille 200 and the panel 100 is smaller.

[0040] In some embodiments, the panel 100 has a first folded edge 110 at one end near the return air grille 200, and the water tray 400 has a second folded edge 420 at one end near the return air grille 200. The second folded edge 420 is located on the side of the first folded edge 110 away from the return air grille 200. The first connector 210 passes through the first folded edge 110 and connects to the second folded edge 420 so that the return air grille 200 abuts against the first folded edge 110.

[0041] It is understandable that by setting the second folded edge 420 on the side of the first folded edge 110 away from the return air grille 200, the connection position between the return air grille 200 and the water tray 400 is closer to the interior of the panel 100, thereby eliminating the gap between the return air grille 200 and the panel 100. Even if the connection between the return air grille 200 and the water tray 400 is loose, its impact on the gap between the return air grille 200 and the panel 100 can be minimized.

[0042] The connection between the second folded edge 420 and the first connector 210 can be one or more of the following methods: plug-in, snap-fit, screw connection, and magnetic connection.

[0043] Specifically, the first connector 210 is screwed to the second flange 420. The first connector 210 is a boss, and the screw passes through the second flange 420 and extends into the boss to be threadedly connected to the screw hole in the boss.

[0044] In some embodiments, a first through hole 111 is provided on the first folded edge 110, and a second through hole 422 aligned with the first folded edge 110 is provided on the second folded edge 420. The first connector 210 passes through the first through hole 111 and the second through hole 422 in sequence and is connected to the second folded edge 420.

[0045] It should be noted that a first through hole 111 is provided on the first folded edge 110 and a second through hole 422 is provided on the second folded edge 420, so that the first connector 210 passes through the first through hole 111 and the second through hole 422 in sequence. The purpose is to make the first connector 210 as close as possible to the center of the panel 100, so that the return air grille 200 is closer to the first folded edge 110.

[0046] The number of first through holes 111, the number of second through holes 422, and the number of first connectors 210 are the same, and each second through hole 422 is set to correspond one-to-one with a first through hole 111.

[0047] The size and shape of the first through hole 111 are the same as those of the second through hole 422.

[0048] In the case of multiple first through holes 111, the multiple first through holes 111 are spaced apart from each other along the length direction of the first folded edge 110.

[0049] In some embodiments, the first connector 210 is configured to change from a first form to a second form under the action of an external force and return to the first form after the external force is removed. The first connector 210 can pass through the first through hole 111 and the second through hole 422 in the first form, and return to the first form and lock connected to the second through hole 422 after passing through the second through hole 422.

[0050] It should be noted that since the first connector 210 can pass through the first through hole 111 and the second through hole 422 in the first configuration, when the first connector 210 changes from the first configuration to the second configuration, the first connector 210 can separate from the second through hole 422 and thus disengage from the second through hole 422 and the first through hole 111.

[0051] It is understandable that by setting the first connector 210 as a deformable structure that can change under the action of external force, the first connector 210 and the water receiving tray 400 can be quickly disconnected and stably connected.

[0052] In some embodiments, the first connector 210 includes a first pin portion 211 and a first spring-loaded portion 212. The first pin portion 211 and the first spring-loaded portion 212 are parallel to each other and spaced apart. When the first connector 210 is in a first state, the first pin portion 211 and the first spring-loaded portion 212 are parallel to each other. When the first connector 210 is in a second state, the first pin portion 211 and the first spring-loaded portion 212 are offset from each other to abut against each other. When the first connector 210 is locked connected to the second through hole 422 in the first state, the first pin portion 211 abuts against one side of the second through hole 422, and the first spring-loaded portion 212 is fastened to one side of the second through hole 422.

[0053] It should be noted that the first pin portion 211 and the first spring-loaded portion 212 are spaced apart from each other so that they can be offset towards each other under the action of external force, thereby reducing the overall width of the first connector 210, so that the first connector 210 can pass through the first through hole 111 and the second through hole 422, and separate from the side of the second through hole 422.

[0054] Since the first spring-loaded part 212 and the first pin part 211 are parallel to each other, when the first connector 210 is in the first state, the first spring-loaded part 212 and the first pin part 211 respectively abut against the two sides opposite to the second through hole 422.

[0055] Generally, to ensure connection stability, the width of the first connector 210 is the same as the width of the first through hole 111 and the second through hole 422. That is, when the first connector 210 is in the first configuration, the first spring-loaded part 212 and the first pin part 211 abut against the opposite sides of the first through hole 111. The width of the first connector 210 is generally the distance from the side of the first spring-loaded part 212 away from the first pin part 211 to the side of the first pin part 211 away from the first spring-loaded part 212.

[0056] Furthermore, in order to facilitate the connection between the first connector 210 and the second through hole 422, the second through hole 422 is usually set as a square hole or a circular hole, that is, the width of the second through hole 422 is the same in both the vertical and horizontal directions, so that the width of the second through hole 422 is the same as the width of the first connector 210.

[0057] Furthermore, in some embodiments, in order to ensure that the first connector 210 has sufficient strength to ensure that the first snap-fit ​​part 212 and the first pin part 211 can be offset towards each other, it is necessary to increase the length of the first snap-fit ​​part 212 and the first pin part 211. However, simply increasing the length of the first snap-fit ​​part 212 and the first pin part 211 will cause the first snap-fit ​​part 212 to be too long and unable to be fastened to the second through hole 422. Therefore, this application provides a groove 201 on the folded edge of the return air grille 200, and sets the first snap-fit ​​part 212 and the first pin part 211 in the groove 201. The depth of the groove 201 increases the length of the first snap-fit ​​part 212 and the first pin part 211, while keeping the length of the first snap-fit ​​part 212 and the first pin part 211 protruding from the end of the return air grille 200 unchanged, ensuring that the first snap-fit ​​part 212 can be smoothly fastened to the side of the second through hole 422.

[0058] In some embodiments, the return air grille 200 is further provided with a second connector 220, the first folded edge 110 is provided with a third through hole 113, the third through hole 113 and the first through hole 111 are offset along the height direction of the first folded edge 110, and the second folded edge 420 is provided with a fourth through hole 424 aligned with the third through hole 113; the second connector 220 is sequentially inserted into the third through hole 113 and the fourth through hole 424.

[0059] It should be noted that the third through hole 113 and the first through hole 111 are offset along the height direction of the first folded edge 110. Since the second through hole 422 is aligned with the first through hole 111 and the fourth through hole 424 is aligned with the third through hole 113, the fourth through hole 424 is offset along the height direction of the second folded edge 420 from the second through hole 422. The second plug-in 220 is inserted into the third through hole 113 and the fourth through hole 424 in sequence. That is, the second plug-in 220 and the first connector 210 are offset and connected to the water receiving tray 400, thereby increasing the connecting parts in the height direction of the two and improving the connection stability between the return air grille 200 and the water receiving tray 400. At the same time, the second plug-in 220 can also be used as a guide to guide the first connector 210 to quickly align with the first through hole 111.

[0060] The number, size, and shape of the fourth through hole 424 are the same as those of the third through hole 113.

[0061] In some embodiments, the first folded edge 110 is provided with a plurality of first through holes 111 and a plurality of third through holes 113, and a first through hole 111 is provided between every two adjacent third through holes 113; that is, on the second folded edge 420, a second through hole 422 is provided between every two adjacent fourth through holes 424.

[0062] In other embodiments, the first folded edge 110 is provided with a plurality of first through holes 111 and a plurality of third through holes 113, and a third through hole 113 is provided between every two adjacent first through holes 111; that is, on the second folded edge 420, a fourth through hole 424 is provided between every two adjacent second through holes 422.

[0063] In some embodiments, the second connector 220 is inserted into the third through hole 113 and the fourth through hole 424. The width of the second connector 220 is the same as that of the third through hole 113 and the fourth through hole 424. Referring to the above-described arrangement of the first through hole 111, the second through hole 422 and the first connector 210, the third through hole 113 and the fourth through hole 424 are made into square holes or circular holes, which facilitates a stable connection between the second connector 220 and the third through hole 113 and the fourth through hole 424.

[0064] In some embodiments, the second connector 220 is a "U"-shaped pin, that is, the transverse surface of the second connector 220 along the direction of the first fold 110 is "U"-shaped.

[0065] In some embodiments, a third connector 230 is provided at the end of the return air grille 200 away from the panel 100, as the first connector 210 is connected to the water tray 400 and the third connector 230 is connected to the chassis 300.

[0066] Specifically, the chassis 300 has a folded edge with a through hole, and the third connector 230 is inserted into the through hole. The third connector 230 can be inserted into the chassis 300 in either a vertical or horizontal direction.

[0067] In some embodiments, the chassis 300 includes a side plate 310 and a bottom plate 320 connected in sequence. The side plate 310 and the bottom plate 320 are perpendicular to each other. One end of the side plate 310 away from the bottom plate 320 is connected to the return air grille 200. The bottom plate 320 is parallel to the return air grille 200 and the panel 100.

[0068] Referring to the above embodiment of the return air grille 200, for example, a fourth folded edge 314 is provided at the end of the side plate 310 away from the bottom plate 320, and a fifth through hole 315 is provided on the fourth folded edge 314, and the third plug-in 230 is inserted into the fifth through hole 315 in the horizontal direction.

[0069] In some embodiments, the present invention also provides a ceiling-mounted unit, which includes the aforementioned indoor unit 10. Since the ceiling-mounted unit has the aforementioned indoor unit 10, that is, includes some or all of the embodiments of the aforementioned indoor unit 10, the corresponding ceiling-mounted unit has the beneficial effects of some or all of the embodiments of the aforementioned indoor unit 10.

[0070] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
