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] The indoor unit casing of existing ceiling-mounted air conditioners is usually composed of a chassis, a return air grille, and a panel connected in sequence. After the three are connected, they form a casing with a cavity. The cavity is hollow, which results in poor overall structural stability. Utility Model Content

[0013] In some embodiments of this utility model, a first insertion structure is provided at one end of the support rod connected to the base plate, and a second insertion structure is provided on the base plate to be inserted into the first insertion structure. The first insertion structure and the second insertion structure are inserted into each other to connect the support rod to the base plate.

[0014] In some embodiments of this utility model, the thickness of the support rod gradually decreases from one end near the side plate to the end away from the side plate.

[0015] In some embodiments of this utility model, the return air grille includes a first sub-return air grille and a second sub-return air grille connected in sequence.

[0032] like Figures 1-6As shown, this utility model provides an indoor unit 10, including a panel 100, a return air grille 200, a chassis 300, and a support frame 400. The panel 100, the return air grille 200, and the chassis 300 are connected in sequence. 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. The side plate 310 connects the return air grille 200 and the bottom plate 320. The return air grille 200 and the panel 100 are both parallel to the bottom plate 320. The support frame 400 includes a support rod 410 and a connecting rod 420. One end of the support rod 410 is connected to the panel 100, and the other end of the support rod 410 is connected to the bottom plate 320. One end of the connecting rod 420 is connected to the support rod 410, and one end of the connecting rod 420 is connected to the side plate 310. The support rod 410 and the connecting rod 420 form a "T"-shaped structure.

[0033] The panel 100, return air grille 200 and chassis 300 are connected in sequence, and the three together form an indoor unit housing with a receiving cavity and return air intake, and the support frame 400 is set in the receiving cavity.

[0034] It should be noted that since the chassis 300 includes a side plate 310 and a bottom plate 320, which are connected in sequence and perpendicular to each other, they form an "L"-shaped structure. In addition to the support rod 410 being connected to the bottom plate 320, the support frame 400 also has a connecting rod 420 connected to the side plate 310. This allows the support frame 400 and the chassis 300 to be connected in two different directions, thereby improving the connection stability between the support frame 400 and the chassis 300. After the panel 100 is connected to the support frame 400, the structural stability of the indoor unit 10 is guaranteed.

[0035] Understandably, the indoor unit 10 has a "T"-shaped support frame 400 between the chassis 300 and the panel 100. The two ends of the support rod 410 of the support frame 400 are connected to the parallel panel 100 and the base plate 320, respectively, to support both. At the same time, one end of the connecting rod 420 of the support frame 400 is connected to the support rod 410, and the other end is connected to the panel 100. By connecting the support frame 400 to the perpendicular side plate 310 and the base plate 320, the connection stability between the support frame 400 and the chassis 300 can be improved. Furthermore, by connecting the support frame 400 to the panel 100, the structural stability of the indoor unit 10 can be improved.

[0036] In some embodiments, the indoor unit 10 further includes a filter device 500, which is connected to the connecting rod 420. The filter device 500 is located on the side of the return air grille 200 near the bottom plate 320 and is spaced apart from the bottom of the return air grille 200.

[0037] The filter device 500 is located on the side of the return air grille 200 near the bottom plate 320 and is spaced apart from the bottom of the return air grille 200. That is, the filter device 500 is located below the return air grille 200, so that the incoming air from the return air grille 200 can be filtered to ensure that all the air entering the indoor unit 10 for ventilation is filtered by the filter device 500.

[0038] Specifically, the return air grille 200 is connected to the panel 100 and parallel to the base plate 320. One end of the connecting rod 420 is connected to the side plate 310, and the other end is connected to the support rod 410. The connecting rod 420 is located below the return air grille 200 and is parallel to the base plate 320. That is, the connecting rod 420 is parallel to the return air grille 200. The filter device 500 is connected to the connecting rod 420 along the length of the connecting rod 420, so that the filter device 500 is parallel to the base plate 320, and thus the filter device 500 is parallel to the return air grille 200.

[0039] The filter device 500 can be a simple filter screen or a filter purification device with purification function, such as a HEPA filter screen.

[0040] In some embodiments, the connecting rod 420 is provided with a mounting groove 411 on at least one side, and each mounting groove 411 corresponds to a filter device 500.

[0041] It should be noted that, in order to ensure that the filter device 500 is located below the return air grille 200 when connected to the connecting rod 420, the mounting groove 411 should not be located on the side of the connecting rod 420 facing the return air grille 200, that is, it should not be located at the top of the connecting rod 420. At the same time, in order to ensure that the filter device 500 has sufficient filtration area for the air intake of the return air grille when connected to the connecting rod 420, the mounting groove 411 should not be located at the bottom of the connecting rod 420. Therefore, the mounting groove 411 can be provided on one side of the connecting rod 420, or the mounting groove 411 can be provided on both sides.

[0042] The mounting groove 411 is generally set along the length of the connecting rod 420. When the filter device 500 is inserted into the mounting groove 411, it is parallel to the base plate 320 and also parallel to the return air grille 200.

[0043] Furthermore, when the filter device 500 is inserted into the mounting groove 411, the connection between the filter device 500 and the mounting groove 411 can be improved by connecting screws between the side wall of the mounting groove 411 and the filter device 500.

[0044] In some embodiments, the indoor unit 10 includes a plurality of filter devices 500, the orthographic projection of which on the return air grille 200 completely covers the return air grille 200.

[0045] It should be noted that the orthographic projection of multiple filter devices 500 on the return air grille 200 completely covers the return air grille 200. That is, the graphic formed by the orthographic projection of multiple filter devices 500 on the return air grille 200 completely covers the return air grille 200. By setting multiple filter devices 500, the area that a single filter device 500 cannot cover is covered, thereby ensuring that the airflow entering from the return air grille 200 can be filtered before entering the heat exchange area of ​​the indoor unit 10.

[0046] Understandably, by having multiple small-area filter devices 500 completely cover the return air grille 200, compared to using a single filter device 500 with a larger coverage area to cover the return air grille 200, it is possible to replace only the filter device 500 in the damaged area when the filter device 500 in a certain area is damaged, resulting in lower maintenance and replacement costs.

[0047] In some embodiments, the indoor unit 10 is provided with a plurality of support frames 400, which are spaced apart from each other along the width direction of the base plate 320.

[0048] In some embodiments, a first plug-in structure is provided at one end of the support rod 410 that is connected to the base plate 320, and a second plug-in structure is provided on the base plate 320 that is plugged into the first plug-in structure. The first plug-in structure and the second plug-in structure are plugged into each other to connect the support rod 410 to the base plate 320.

[0049] The first plug-in structure can be one of a concave structure and a convex structure set on the end plate of the support rod 410, and the second plug-in structure is the other of the concave structure and the convex structure. The two are joined together to form a plug-in, which can quickly connect the support rod 410 and the base plate 320, and can also achieve quick positioning and quick connection through the concave-convex fit.

[0050] Specifically, the first insertion structure is a connecting shaft, and the second insertion structure is a connecting hole that mates with the connecting shaft.

[0051] Furthermore, the connecting shaft is a polygonal or irregularly shaped shaft, and the connecting hole is matched and set accordingly. Compared with the circular shaft and circular hole, it cannot rotate, which can prevent the support rod 410 from shaking.

[0052] Furthermore, the end of the support rod 410 is provided with multiple connecting shafts, which are spaced apart from each other. The base plate 320 is provided with multiple connecting holes that match each other. By connecting the multiple connecting shafts with the multiple connecting holes one by one, the support rod 410 can be prevented from rotating relative to the base plate 320, the support rod 410 can be prevented from shaking, and the stability of the connection between the support rod 410 and the base plate 320 can be improved.

[0053] In some embodiments, the support rod 410 is connected to the base plate 320 by screws.

[0054] In some embodiments, the support rod 410 is connected to the base plate 320 by a snap-fit ​​connection.

[0055] In some embodiments, the thickness of the support rod 410 gradually decreases from one end near the side plate 310 toward the end away from the side plate 310.

[0056] It should be noted that the thickness direction of the support rod 410 is the same as the width direction of the base plate 320. The heat exchange area of ​​the indoor unit 10 is located below the panel 100. After the airflow enters from the return air grille 200, it flows along the length direction of the base plate 320, first passing through the support rod 410, and then flowing to the heat exchange area.

[0057] Understandably, the width of the support rod 410 gradually decreases from the end closest to the side plate 310 toward the end furthest from the side plate 310. That is, the thickness of the support rod 410 gradually decreases along the airflow direction after entering the return air grille 200 and then into the main body of the indoor unit 10. This causes the support rod 410 itself to form an air guiding structure, guiding the airflow passing through the support rod 410 and avoiding the formation of turbulence at the end of the support rod 410.

[0058] In some embodiments, the return air grille 200 includes a first sub-return air grille 210 and a second sub-return air grille 220 connected in sequence. The first sub-return air grille 210 and the second sub-return air grille 220 are vertical or inclined. The first sub-return air grille 210 is connected to the side plate 310, the second sub-return air grille 220 is connected to the panel 100, and the second sub-return air grille 220 is parallel to the bottom plate 320.

[0059] Generally, the first sub-return air grille 210 and the second sub-return air grille 220 are set vertically or obliquely, forming an "L" shaped structure.

[0060] Furthermore, the return air grille 200 also includes a grille side plate 230. The first sub-return air grille 210 and the second sub-return air grille 220 are both connected to the grille side plate 230. The grille side plate 230 is connected to one side of the first sub-return air grille 210 and the second sub-return air grille 220, forming an integral structure with the first sub-return air grille 210 and the second sub-return air grille 220.

[0061] Furthermore, the grille side panel 230, the first sub-return air grille 210, and the second sub-return air grille 220 are integrally formed structures.

[0062] In some embodiments, the indoor unit 10 further includes a water tray 600, which includes a first water receiving part 610. The first water receiving part 610 is disposed close to the panel 100 and is parallel to the panel 100. One end of the support rod 410 is connected to the panel 100, and the other end is also connected to the first water receiving part 610.

[0063] It is understandable that one end of the support rod 410 is connected to both the panel 100 and the first water receiving part 610, which can improve the connection stability between the support rod 410 and the panel 100 and the first water receiving part 610, thereby improving the structural stability of the indoor unit 10.

[0064] Furthermore, the support rod 410 is connected to the panel 100 and the first water receiving part 610 by screws. One end of the panel 100 has a first connecting piece, and one end of the first water receiving part 610 is provided with a second connecting piece. The screws pass through the first connecting piece and the second connecting piece in sequence and are connected to the end of the support rod 410, thereby realizing that the end of the support rod 410 is simultaneously connected to the first water receiving part 610 and the panel 100.

[0065] In some embodiments, the water receiving tray 600 further includes a second water receiving portion 620 connected to the first water receiving portion 610. The first water receiving portion 610 and the second water receiving portion 620 are perpendicular or inclined to each other, and the second water receiving portion 620 is located on the side of the support rod 410 away from the side plate 310.

[0066] Specifically, the first water receiving part 610 and the second water receiving part 620 can be connected by a connector. One end of the connector is connected to one end of the first water receiving part 610 and is arranged perpendicularly or obliquely to the first water receiving part 610. The second water receiving part 620 is connected to the connector.

[0067] 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.

[0068] 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.
