Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air guide plate assembly, an indoor unit, and an air conditioner. Background Technology

[0002] Cabinet-type air handling units are generally quite tall, and gaps can easily form between the various injection-molded structural components during assembly, affecting the overall appearance and precision of the unit. The main reasons for these gaps are: 1. The dimensions of the injection-molded structural components are over one meter, amplifying the deformation issues that occur during the injection molding process, making it easier for gaps to exist when assembling with other components; 2. The injection-molded structural components undergo thermal expansion and contraction during the cooling and heating processes of the air handling unit, causing changes in the fit clearances.

[0003] The air guide plates of existing cabinet-type air handling equipment are prone to deformation due to their length exceeding 1 meter during injection molding. Current solutions generally require the use of sheet metal parts for support and correction of deformation, which is costly, structurally complex, and wastes assembly time. The air guide plate and the front panel are spliced ​​together with zero clearance, making it difficult to control deformation in the length direction. There are also gaps between the air guide plates and the front panel. When the air guide plates are closed, there are uneven gaps between the air guide plates and between the air guide plates and the left and right side panels, resulting in poor consistency and affecting the appearance. Utility Model Content

[0004] This utility model provides an air guide plate assembly, an indoor unit, and an air conditioner to solve the defects in the prior art where the air guide plate, when spliced, is prone to gap fit problems or deformation under thermal expansion and contraction.

[0005] This utility model provides an air guide plate assembly, including: Front panel, having a first overlapping portion; Multiple air guide plates are rotatably mounted on the front panel, and each air guide plate has a second overlapping portion on the side near the front panel, and a third overlapping portion on the side of each air guide plate near the adjacent air guide plate; wherein, The second overlapping portion is adapted to overlap with the first overlapping portion, and there is a first gap between the second overlapping portion and the first overlapping portion. Two adjacent air guide plates are adapted to overlap each other through the third overlapping portion, and there is a second gap between two adjacent third overlapping portions.

[0006] According to the air guide plate assembly provided by this utility model, the first overlapping portion includes a first stepped surface; the second overlapping portion includes a second stepped surface, adapted to overlap with the first stepped surface, and the first gap is located between the side of the second stepped surface facing the front panel and the side of the first stepped surface facing the air guide plate. The overlapping and fitting via the stepped surfaces, with a certain gap (i.e., the first gap) between the two stepped surfaces, reduces the adverse effects caused by the air guide plate deforming due to thermal expansion and contraction and pressing against the front panel.

[0007] According to the air guide plate assembly provided by this utility model, the third overlapping portion includes: a third stepped surface, adapted to overlap with another third stepped surface of an adjacent air guide plate, and the second gap is located between the sides of the two adjacent third stepped surfaces facing the adjacent air guide plate. The overlapping and fitting via the stepped surfaces, with a certain gap (i.e., the second gap) between the two stepped surfaces, reduces the adverse effects caused by the air guide plate deforming due to thermal expansion and contraction and squeezing other air guide plates.

[0008] According to the air guide plate assembly provided by this utility model, there is a top gap between the top of the air guide plate and the front panel, and a bottom gap between the bottom of the air guide plate and the front panel.

[0009] According to the air guide plate assembly provided by this utility model, the top gap is smaller than the bottom gap. The top of the air guide plate is the main viewing area of ​​the machine, and the bottom is a non-main viewing area. Therefore, the top gap of the air guide plate is designed to be smaller than the bottom gap to ensure the appearance effect of the main viewing area.

[0010] According to the air guide plate assembly provided by this utility model, the air guide plate is further provided with a hanging column; the air guide plate assembly further includes: an air outlet frame, provided with a hanging plate, and the hanging column is rotatably inserted into the hanging plate.

[0011] According to the air guide plate assembly provided by this utility model, the hanging column is movably engaged with the hanging plate along the axial direction. This allows the air guide plate to deform downwards during the thermal expansion and contraction process of the machine, using the bottom gap allowance to compensate for the deformation caused by thermal expansion and contraction, thereby controlling the change in the top gap and ensuring the consistency of the appearance of the main viewing area.

[0012] According to the air guide plate assembly provided by this utility model, multiple hanging columns are arranged along the length direction of the air guide plate; multiple hanging plates are arranged along the length direction of the air outlet frame.

[0013] This utility model also provides an indoor unit, including: the air guide plate assembly of this utility model.

[0014] This utility model also provides an air conditioner, including: the air guide plate assembly or indoor unit of this utility model.

[0015] This utility model provides an air guide plate assembly, comprising: a front panel and a plurality of air guide plates. The front panel has a first overlapping portion; the plurality of air guide plates are rotatably disposed on the front panel, and each air guide plate has a second overlapping portion on the side near the front panel, and a third overlapping portion on the side of each air guide plate near an adjacent air guide plate. The second overlapping portion is adapted to overlap with the first overlapping portion, and a first gap exists between the second overlapping portion and the first overlapping portion. Two adjacent air guide plates are adapted to overlap each other through the third overlapping portion, and a second gap exists between two adjacent third overlapping portions. The air guide plate assembly provided by this utility model uses an overlapping fit between the front panel and the air guide plates, as well as between the air guide plates themselves, and the gaps between the overlapping portions allow for reduced fitting problems caused by deformation when the air guide plates deform due to thermal expansion and contraction, thereby eliminating the need for sheet metal parts for supporting and correcting deformation as in the prior art, thus reducing costs, simplifying the structure, and reducing assembly time.

[0016] Furthermore, the indoor unit provided by this utility model includes the air guide plate assembly in the above embodiments of this utility model, and therefore has the same advantages as above.

[0017] Furthermore, the air conditioner provided by this utility model includes the air guide plate assembly or indoor unit in the above embodiments of this utility model, and therefore has the same advantages as above. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this embodiment, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to 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 embodiment based on the specific circumstances.

[0032] In this embodiment of the utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] The following is combined with Figures 1 to 8 This invention describes an air guide plate assembly. The air guide plate assembly includes: a front panel 1 and a plurality of air guide plates 2.

[0034] The front panel 1 has a first overlapping portion 11; a plurality of air guide plates 2 are rotatably disposed on the front panel 1, and the air guide plate 2 has a second overlapping portion 21 on the side of the air guide plate 2 close to the front panel 1, and a third overlapping portion 22 on the side of the air guide plate 2 close to another air guide plate 2 adjacent to it.

[0035] The second overlapping portion 21 is adapted to overlap with the first overlapping portion 11, and there is a first gap 41 between the second overlapping portion 21 and the first overlapping portion 11. Two adjacent air guide plates 2 are adapted to overlap each other through a third overlapping portion 22, and there is a second gap 42 between two adjacent third overlapping portions 22.

[0036] Specifically, the front panel 1 has an area for mounting an air guide plate 2, which is rotatably mounted on the front panel 1 for adjusting the airflow direction.

[0037] The front panel 1 has a first overlapping portion 11 located on the inner side of the front panel 1. The left and right sides of the air guide plate 2 each have a second overlapping portion 21 and a third overlapping portion 22. The second overlapping portion 21 is adapted to overlap and cooperate with the first overlapping portion 11, and adjacent air guide plates 2 are overlapped and cooperated with each other through the third overlapping portion 22. Figure 2 In the structure shown, the air guide plate 2 is in the closed state, with one side of the air guide plate 2 overlapping the front panel 1 and the other side overlapping the adjacent air guide plate 2. For example... Figure 1 In the structure shown, the air guide plate 2 is in the open state. The overlapping method described above ensures that the gaps are blocked, hindering light transmission and achieving an aesthetically pleasing effect.

[0038] In such Figure 5 and Figure 6 In the structure shown, when the air guide plate 2 is in the closed state, there is a first gap 41 between the first overlapping part 11 and the second overlapping part 21, and a second gap 42 between the two third overlapping parts 22. This allows the fitting problems caused by the deformation to be reduced when the air guide plate 2 is deformed due to thermal expansion and contraction. For example, the air guide plate 2 can avoid the phenomenon of being difficult to close completely or getting stuck due to deformation.

[0039] Preferably, the lengths of the first gap 41 and the second gap 42 are greater than 1 mm.

[0040] Furthermore, since there are gaps between the air guide plates 2 and between the air guide plate 2 and the front panel 1, the sheet metal parts used for supporting and correcting deformation in the prior art can be omitted, thereby reducing costs, simplifying the structure, and reducing assembly time. The indoor unit of this utility model omits the vertical oscillating blade air guide, directly using a double air guide plate 2 mode to guide the airflow. It adopts an injection-molded structure, does not rely on sheet metal parts for support and correction, has a thin wall thickness, and has minimal impact on the airflow volume. The vertical oscillating blade air guide structure is omitted; the air guide plate 2 serves a guiding function when open and a decorative function when closed, resulting in low cost and a simple structure.

[0041] This utility model provides an air guide plate assembly, which includes: a front panel 1 and a plurality of air guide plates 2. The front panel 1 has a first overlapping portion 11; the plurality of air guide plates 2 are rotatably disposed on the front panel 1, and each air guide plate 2 has a second overlapping portion 21 on the side of the air guide plate 2 close to the front panel 1, and a third overlapping portion 22 on the side of the air guide plate 2 close to another adjacent air guide plate 2. The second overlapping portion 21 is adapted to overlap with the first overlapping portion 11, and a first gap 41 is formed between the second overlapping portion 21 and the first overlapping portion 11. Two adjacent air guide plates 2 are adapted to overlap each other through the third overlapping portion 22, and a second gap 42 is formed between two adjacent third overlapping portions 22. The present invention provides an air guide plate assembly in which the front panel 1 and the air guide plate 2, as well as the air guide plate 2 and the air guide plate 2 are connected by an overlapping joint. Furthermore, there is a gap between the overlapping parts, so that when the air guide plate 2 is deformed due to thermal expansion and contraction, the fitting problems caused by deformation can be reduced by the first gap 41 and the second gap 42. This eliminates the need for sheet metal parts that support and correct deformation in the prior art, thereby reducing costs, simplifying the structure, and reducing assembly time.

[0042] In one embodiment of this utility model, the first overlapping portion 11 includes a first stepped surface; the second overlapping portion 21 includes a second stepped surface adapted to overlap with the first stepped surface, and the first gap 41 is located between the side of the second stepped surface facing the front panel 1 and the side of the first stepped surface facing the air guide plate 2. Figure 5 and Figure 6 In the structure shown, both the first overlapping part 11 and the second overlapping part 21 adopt a stepped surface structure, which is used for overlapping and fitting. When the two stepped surfaces overlap, there is a certain gap (i.e., the first gap 41), which reduces the adverse effects caused by the deformation of the air guide plate 2 due to thermal expansion and contraction, which would then compress the front panel 1. It should be understood that the first gap 41 is located along the width direction of the air guide plate 2 between the first stepped surface and the second stepped surface (i.e., the first gap 41 is located between the side of the second stepped surface facing the front panel 1 and the side of the first stepped surface facing the air guide plate 2), mainly to reduce the lateral deformation of the air guide plate 2 caused by thermal expansion and contraction.

[0043] In one embodiment of this utility model, the third overlapping portion 22 includes: a third stepped surface adapted to overlap with another third stepped surface of an adjacent air guide plate 2, and a second gap 42 located between the two adjacent third stepped surfaces on their sides facing the adjacent air guide plate 2. Figure 5 and Figure 6In the structure shown, the third overlapping part 22 adopts a stepped surface structure, and the two stepped surfaces overlap and fit together. When the two stepped surfaces overlap, there is a certain gap (i.e., the second gap 42), which reduces the adverse effects caused by the deformation of the air guide plate 2 due to thermal expansion and contraction, which would then compress other air guide plates 2. It should be understood that the second gap 42 is located between two adjacent third stepped surfaces along the width direction of the air guide plate 2 (i.e., the second gap 42 is located between the sides of two adjacent third stepped surfaces facing the adjacent air guide plate 2), mainly to reduce the lateral deformation of the air guide plate 2 caused by thermal expansion and contraction.

[0044] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, there is a top gap 43 between the top of the air guide plate 2 and the front panel 1, and a bottom gap 44 between the bottom of the air guide plate 2 and the front panel 1. Preferably, the top gap 43 is smaller than the bottom gap 44. The air guide plate assembly in this embodiment is adapted to an air conditioning unit. The top of the air guide plate 2 is the main viewing area of ​​the machine, and the bottom is a non-main viewing area. Therefore, the top gap 43 of the air guide plate 2 is designed to be smaller than the bottom gap 44 to ensure the appearance effect of the main viewing area.

[0045] In one embodiment of this utility model, such as Figure 7 and Figure 8 As shown, the air guide plate 2 is also provided with a hanging post 23. The air guide plate assembly also includes: an air outlet frame 3, which is provided with a hanging plate 31, and the hanging post 23 is rotatably inserted into the hanging plate 31. Preferably, the hanging post 23 is inserted from the bottom of the hanging plate 31 and is axially movable with the hanging plate 31. In this embodiment, the hanging posts 23 are inserted into the hanging plates 31 on both sides of the air outlet frame 3 from below, which allows the air guide plate 2 to deform downwards during the thermal expansion and contraction process of the machine. The bottom gap 44 is used to compensate for the deformation caused by thermal expansion and contraction, thereby controlling the change of the top gap 43 and ensuring the consistency of the appearance of the main viewing area.

[0046] In one embodiment of this utility model, multiple hanging posts 23 are arranged along the length of the air guide plate 2; multiple hanging plates 31 are arranged along the length of the air outlet frame 3. In this embodiment, the multiple hanging posts 23 and multiple hanging plates 31 are interlocked to ensure the stable connection of the air guide plate 2 and smooth opening / closing. Furthermore, the interlocking connection structure of the hanging posts and hanging plates 31 facilitates processing and assembly.

[0047] This utility model also provides an indoor unit. The indoor unit includes the air guide plate assembly described in the above embodiments of this utility model. The air guide plate assembly provided by this utility model is suitable for air conditioning cabinet units and adopts a vertical air guide plate 2 structure.

[0048] The present invention provides an indoor unit that includes the air guide plate assembly in the above embodiments of the present invention, and therefore has the same advantages as described above.

[0049] This utility model also provides an air conditioner. The air conditioner includes: the air guide plate assembly or indoor unit as described in the above embodiments of this utility model.

[0050] The present invention provides an air conditioner that includes the air guide plate assembly or indoor unit in the above embodiments of the present invention, and therefore has the same advantages as described above.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
