Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically providing an indoor air conditioning unit and an air conditioner. Background Technology

[0002] An air conditioner indoor unit typically consists of a casing and a front panel. The top of the casing usually has an air intake grille, through which indoor air can enter the casing when the air conditioner is running. The front panel is located on the front side of the casing and is used to isolate the interior of the indoor unit from the external environment, and also serves a decorative purpose, enhancing the overall appearance of the indoor unit.

[0003] However, currently, the front panel is usually fixed directly to the front of the casing, without any matching structure between the front panel and the casing. After the entire machine has been assembled for a long time, the front panel will deform due to prolonged use. In addition, since there is no matching structure between the front panel and the casing, a large gap can easily appear between the front panel and the top of the casing.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem of flash gaps forming between the front panel and the cover due to front panel deformation in the prior art.

[0006] In a first aspect, the present invention provides an indoor air conditioner unit, the indoor air conditioner unit including a housing and a front panel, the front panel being detachably disposed on the front side of the housing, the side of the front panel facing the housing being provided with at least one first mating structure, and the front side of the housing being correspondingly provided with at least one second mating structure, the first mating structure and the second mating structure being engaged and connected, and when the front panel is installed to the housing, at least a portion of the first mating structure extends into the second mating structure and is in contact with at least a portion of the second mating structure.

[0007] In the preferred technical solution of the above-mentioned air conditioner indoor unit, there are multiple first docking structures, and the multiple first docking structures are disposed on the front panel near its top side, and at least a portion of the multiple first docking structures are arranged along the length direction of the front panel.

[0008] In the preferred technical solution of the above-mentioned air conditioner indoor unit, the first docking structure includes a first part and a second part connected to each other. The first end of the first part is connected to the side of the front panel facing the cover. The second part extends from the second end of the first part in a direction away from the top of the cover. When the front panel is installed to the cover, at least the second part extends into the second docking structure and is in contact with at least a part of the second docking structure.

[0009] In the preferred technical solution of the above-mentioned air conditioner indoor unit, the second docking structure includes a groove with the groove opening upward. When the front panel is installed onto the cover, at least the second part extends into the groove from top to bottom and fits against at least a part of the inner wall of the groove.

[0010] In the preferred technical solution of the above-mentioned air conditioner indoor unit, the top of the casing is provided with an air inlet grille, the groove includes a groove bottom and a side wall arranged circumferentially along the groove bottom, the side wall includes a first side wall and a second side wall opposite to each other, and a third side wall disposed between the first side wall and the second side wall, at least a portion of the third side wall is located outside the air inlet grille, and the second portion is at least in contact with a portion of the inner wall of the third side wall.

[0011] In the preferred embodiment of the above-mentioned air conditioner indoor unit, the third sidewall is parallel to the second part.

[0012] In the preferred embodiment of the above-mentioned air conditioner indoor unit, the ends of the first sidewall and the second sidewall away from the bottom of the slot are connected to the bottom of the air inlet grille.

[0013] In the preferred embodiment of the above-mentioned air conditioner indoor unit, the first docking structure is provided with a reinforcing rib on the side facing the top of the cover.

[0014] In the preferred embodiment of the above-mentioned air conditioner indoor unit, at least one snap-fit ​​part is provided on the inner side of the front panel facing the cover, and at least one slot is provided on the cover accordingly, and the snap-fit ​​part is engaged with the slot.

[0015] In the technical solution of this utility model, the front panel of the air conditioner indoor unit is detachably mounted on the front side of the casing. At least one first mating structure is provided on the side of the front panel facing the casing, and at least one second mating structure is correspondingly provided on the front side of the casing. The first and second mating structures engage with each other. When the front panel is installed onto the casing, at least a portion of the first mating structure extends into the second mating structure and is in close contact with at least a portion of the second mating structure. In this way, through the cooperation and contact between the first and second mating structures, the casing not only provides sufficient support for the front panel but also pulls the front panel towards the casing. Therefore, even if the front panel deforms, the cooperation of the first and second mating structures effectively prevents the formation of gaps between the front panel and the casing.

[0016] Furthermore, the front panel is provided with multiple first mating structures, which are located near the top side of the front panel, and at least a portion of the multiple first mating structures are arranged along the length of the front panel. That is to say, when the front panel and the cover are assembled, multiple sets of first mating structures and second mating structures cooperate with each other, thereby better supporting and pulling the front panel and better avoiding the formation of gaps between the front panel and the cover.

[0017] Furthermore, the first mating structure includes a first part and a second part connected to each other. The first end of the first part is connected to the side of the front panel facing the housing. The second part extends from the second end of the first part in a direction away from the top of the housing, thereby forming a hook-like structure that is generally open downwards. The second mating structure includes a body with a groove formed thereon, the groove opening upwards. When the front panel is installed onto the housing, at least the second part extends from top to bottom into the groove and abuts against at least a portion of the inner wall of the groove. That is, the second part is inserted into the groove and abuts against the inner wall of the groove. In this case, the contact area between the groove and the second part is larger, thereby better supporting and pulling the second part, and thus better preventing the formation of a gap between the front panel and the housing due to insufficient support provided by the housing.

[0018] Furthermore, a reinforcing rib is provided on the side of the first docking structure facing the top of the cover. This reinforcing rib can effectively enhance the strength of the first docking structure and improve the reliability of the fit between the first docking structure and the second docking structure.

[0019] Furthermore, at least one snap-fit ​​part is provided on the inner side of the front panel facing the cover, and at least one corresponding slot is provided on the cover. The snap-fit ​​part and the slot are engaged and connected. During installation, the snap-fit ​​part is matched and connected with the corresponding slot, so that the front panel can be detachably set on the front side of the cover to cover the components set inside the cover and improve the overall aesthetics of the machine.

[0020] Secondly, this utility model also provides an air conditioner, which is equipped with an indoor air conditioning unit as described in any of the aforementioned solutions.

[0021] It should be noted that this air conditioner has all the technical effects of the aforementioned indoor air conditioner unit, which will not be repeated here. Attached Figure Description

[0036] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0037] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," and "right," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] Currently, because there is no matching structure between the front panel and the casing, specifically, as... Figure 1 and Figure 2As shown, the inner side of the front panel 100 is typically provided with a raised rib 200, and the upper part of the cover 300 is correspondingly provided with a support rib 400. When assembled, the raised rib 200 and the support rib 400 overlap each other. However, the raised rib 200 and the support rib 400 only overlap, and the cover 300 cannot provide any support for the front panel 100. After prolonged use, a large gap is likely to appear between the front panel 100 and the top of the cover 300. To address this, the air conditioner indoor unit of this application extends at least a portion of the first mating structure provided on the side of the front panel facing the cover into a second mating structure provided on the front side of the top of the cover, and at least a portion of the second mating structure is in contact with each other. In this way, the cover can provide sufficient support for the front panel and also pull the front panel towards the cover, thereby effectively preventing the formation of a gap between the front panel and the cover.

[0040] The following is combined Figures 3 to 8 This paper describes possible implementations of the indoor unit of the air conditioner according to this utility model.

[0041] like Figures 3 to 8 As shown, the indoor unit of the air conditioner includes a casing 2 and a front panel 1. The casing 2 is generally a hollow, elongated structure, which typically houses components such as a heat exchanger and an indoor fan. An air inlet grille 21 is located on its top, and the air inlet grille 21 includes multiple horizontal ribs 211 and multiple vertical ribs 212, which are arranged alternately. When the indoor unit is running, air from the indoor space enters the casing 2 through the air inlet grille 21 under the action of the indoor fan, exchanges heat with the heat exchanger inside, and then returns to the indoor space, thus adjusting the temperature of the indoor space. The front panel 1 is generally a plate-like structure, and its shape and size are roughly equivalent to the front side of the casing 2. It is typically detachably mounted on the front side of the casing 2. This front panel 1 isolates the interior of the casing 2 from the external environment, shielding and protecting the components inside. Simultaneously, the front panel 1 also serves a decorative function, for example, by designing its shape, pattern, and material to enhance the overall aesthetics of the device. In this embodiment, the front panel 1 faces the side of the casing 2 (approximately...) Figure 3At least one first docking structure 11 is provided on the inner side of the front panel 1, and at least one second docking structure 22 is provided on the front side of the air intake grille 21. The first docking structure 11 and the corresponding second docking structure 22 are engaged and connected. When the front panel 1 is installed onto the cover 2, at least a portion of the first docking structure 11 extends into the second docking structure 22 and is in close contact with at least a portion of the second docking structure 22. In this way, the contact area between the cover 2 and the front panel 1 is increased through the engagement and contact between the first docking structure 11 and the second docking structure 22. This allows the cover 2 to provide sufficient support for the front panel 1 and pull the front panel 1 towards the cover 2. Thus, even if the front panel 1 is deformed, the engagement of the first docking structure 11 and the second docking structure 22 can effectively prevent the formation of gaps between the front panel 1 and the cover 2.

[0042] It should be noted that, alternatively, the top of the casing 2 may not have an air inlet grille 21, but only an air inlet, with the second mating structure 22 positioned in front of the air inlet on the casing 2. Of course, the second mating structure 22 can also be positioned in other possible locations on the front of the casing 2. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific position of the second mating structure 22 according to the specific application scenario, as long as it can match and connect with the corresponding first mating structure 11 when the front panel 1 is installed on the front of the casing 2, and prevent the formation of a gap between the front panel 1 and the casing 2 through its cooperation with the first mating structure 11.

[0043] like Figures 3 to 5 , Figure 7 , Figure 8 As shown, the front panel 1 faces the side of the housing 2 (approximately) Figure 3 Two first docking structures 11 are provided on the inner side of the front panel 1. Both first docking structures 11 are located near the top of the front panel 1 and arranged along its length. Correspondingly, two second docking structures 22 are provided on the front side of the air intake grille 21, arranged sequentially along its length. It should be noted that in this embodiment, the length direction of the front panel 1 and the length direction of the air intake grille 21 are parallel to each other, and are approximately [missing information]. Figure 5 The direction indicated by the middle arrow. When the front panel 1 and the cover 2 are assembled, at least a portion of each of the two first mating structures 11 extends into the corresponding second mating structure 22 and is respectively in contact with at least a portion of the corresponding second mating structure 22. In this way, multiple sets of first mating structures 11 and second mating structures 22 cooperate with each other, thereby better supporting and pulling the front panel 1 and better preventing the formation of gaps between the front panel 1 and the cover 2.

[0044] It should be noted that the inner side of the front panel 1 can also be provided with three, four, or more first docking structures 11. Correspondingly, the front side of the air intake grille 21 is provided with a corresponding number of second docking structures 22, as long as the first docking structure 11 and the corresponding second docking structure 22 can be connected when the front panel 1 is installed on the front side of the cover 2. It should also be noted that when there are multiple first docking structures 11, all of the first docking structures 11 can be arranged along the length direction of the front panel 1, or only a portion of the first docking structures 11 can be arranged along the length direction of the front panel 1. Taking the provision of three first docking structures 11 on the inner side of the front panel 1 as an example, all three first docking structures 11 can be arranged sequentially along the length direction of the front panel 1. Obviously, it is also possible that two of the first docking structures 11 are arranged sequentially along the length direction of the front panel 1, and the third first docking structure 11 is located below the first two first docking structures 11.

[0045] like Figures 3 to 5 , Figure 7 , Figure 8 As shown, the first docking structure 11 is generally a flat structure, including a first part 111 and a second part 112 connected to each other. The first end of the first part 111 is connected to the side of the front panel 1 facing the housing 2 (approximately). Figure 3 The inner side of the front panel 1 is connected to the first part 111, and the second end of the first part 112 is connected to the first end of the second part 112. The second end of the second part 112 extends from the second end of the first part 111 in a direction away from the top of the cover 2 and away from the front panel 1 (approximately). Figure 8 The first docking structure 11 extends downward and to the right, thereby forming a hook-shaped structure that is generally open downward. The second docking structure 22 includes a groove 221 with its opening facing upward. The groove 221 includes a bottom 2211 and sidewalls arranged circumferentially along the bottom 2211. The sidewalls include a first sidewall 2212 and a second sidewall (not shown) that are opposite each other, and a third sidewall 2213 disposed between the first sidewall 2212 and the second sidewall. The side opposite to the third sidewall 2213 is configured as an opening. The first sidewall 2212, the second sidewall, the third sidewall 2213 and the bottom 2211 are all generally plate-like structures, thus forming a groove 221 with its opening facing upward.

[0046] Continue to refer to Figures 3 to 5 , Figure 7 , Figure 8 The first sidewall 2212 and the second sidewall extend vertically, and the ends of these two sidewalls away from the bottom of the tank 2211 (approximately) Figure 8The rear side of the first sidewall 2212 and the upper end of the second sidewall is connected to the bottom of the foremost transverse rib 211 of the air intake grille 21. Obviously, the upper ends of the first sidewall 2212 and the second sidewall can also be connected to the front side of the foremost transverse rib 211 of the air intake grille 21. The first sidewall 2212 and the second sidewall are located near the sides of the front panel 1 (approximately...). Figure 8 Both the first sidewall 2212 and the front edge of the second sidewall are set as inclined edges, inclined from the position near the front panel 1 to the direction away from the front panel 1 (approximately). Figure 8 The third sidewall 2213 is inclined downwards from left to right. Its two sides connect to the front sides of the first sidewall 2212 and the second sidewall, respectively, thus placing the third sidewall 2213 on the outside of the air intake grille 21. This makes it easier for the second part 112 to be inserted into the groove 221. The third sidewall 2213 is approximately inclined from the position near the front panel 1 towards the direction away from the front panel 1 (approximately...). Figure 8 A sloping edge (sloping downwards from left to right) is provided, the sloping angle of which is approximately the same as the sloping angle of the second part 112, and the two are parallel to each other. When the front panel 1 is installed onto the cover 2, the second part 112 extends from top to bottom into the groove 221, and the second part 112 is in contact with the inner wall of the third side wall 2213. That is, when the front panel 1 is installed onto the cover 2, the second part 112 is inserted into the groove 221 and is in contact with the inner wall of the third side wall 2213. In this case, the entire third side wall 2213 of the groove 221 is in full contact with the second part 112, and the contact area is large, so that the second part 112 can be better supported. Furthermore, the contact between the third side wall 2213 and the second part 112 can better pull the second part 112 toward the cover 2, thereby better supporting the front panel 1 and bringing the front panel 1 as close to the cover 2 as possible, avoiding the formation of a gap between the front panel 1 and the cover 2.

[0047] It should be noted that the third sidewall 2213 may also be located only in part on the outer side of the front of the air intake grille 21. For example, the lower half of the third sidewall 2213 may be located below the air intake grille 21, and the upper half may be located on the outer side of the air intake grille 21.

[0048] It should be noted that the third sidewall 2213 may not be parallel to the second part 112. Instead, only the inner wall of the third sidewall 2213 may be parallel to the second part 112, or a part of the inner wall of the third sidewall 2213 may be parallel to the second part 112, as long as the second part 112 can fit into the groove 221 when it is inserted into the groove.

[0049] It should be noted that the second part 112 can also extend from the second end of the first part 111 in a direction away from the top of the casing 2 and close to the front panel 1, according to... Figure 8 As shown in the diagram, the second part 112 extends downward and to the left from the second end of the first part 111, and a sidewall correspondingly fitted to the second part 112 is provided in the groove 221. Obviously, the first mating structure 11 may not consist of the first part 111 and the second part 112, but rather be an inclined plate-like structure with a magnetic attraction structure (such as a magnet) on it. A magnetically attracted structure (such as an iron sheet) is provided on the third sidewall 2213 of the groove 221. When the front panel 1 is installed onto the cover 2, the plate-like structure extends into the groove 221 and matches with the magnetically attracted structure, thereby providing sufficient support for the front panel 1 through the cover 2.

[0050] like Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, the first docking structure 11 faces the side of the top of the housing 2 (approximately). Figure 8 A reinforcing rib 113 is provided on the upper side of the first mating structure 11. The reinforcing rib 113 includes three parallel vertical ribs extending along the length of the first mating structure 11 from the first end of the first part 111 to a position near the second end of the second part 112. These vertical ribs effectively enhance the strength of the first mating structure 11 and improve the reliability of the fit between the first mating structure 11 and the second mating structure 22, thereby better preventing the formation of gaps between the front panel 1 and the cover 2. Obviously, the reinforcing rib 113 may also include only one or two vertical ribs, or four, five, or other numbers of vertical ribs. Obviously, the reinforcing rib 113 may also include transverse ribs. Of course, the reinforcing rib 113 may also be provided at other locations on the first mating structure 11, for example, on the side of the first mating structure 11 along its width direction, etc. Obviously, the first mating structure 11 may also not have a reinforcing rib 113.

[0051] like Figures 3 to 8As shown, two snap-fit ​​parts 12 are provided on the inner side of the front panel 1 facing the housing 2. Viewed along the length of the front panel 1, the two snap-fit ​​parts 12 are respectively located near the left and right sides of the front panel 1, and are situated outside the two first mating structures 11. The snap-fit ​​parts 12 are generally upward-opening, flat, hook-shaped structures, with pins 121 located near the ends of the snap-fit ​​parts 12. The housing 2 has two corresponding slots 23, which are generally flat structures, and each slot 23 has a shaft hole 231 formed on its corresponding sidewall. The front panel 1 is detachably mounted on the front side of the housing 2 through the snap-fit ​​parts 12 and the corresponding slots 23, and the pins 121 and the corresponding shaft holes 231. This allows the front panel 1 to conceal components inside the housing 2, improving the overall aesthetics of the device. It should be noted that one snap-fit ​​part 12 can be located on the outside of the two first mating structures 11, and the other snap-fit ​​part 12 can be located between the two first mating structures 11. Of course, both snap-fit ​​parts 12 can also be located between the two first mating structures 11. Obviously, three, four, or more snap-fit ​​parts 12 can be provided on the inner side of the front panel 1. Correspondingly, the air intake grille 21 is provided with a corresponding number of slots 23, as long as the snap-fit ​​parts 12 can engage with the corresponding slots 23 when the front panel 1 is installed on the front side of the cover 2.

[0052] Based on the above structure, when installing the front panel 1 onto the housing 2, firstly, insert the two snap-fit ​​parts 12 into the corresponding slots 23, so that the pin 121 matches the shaft hole 231. Then, rotate the front panel 1 so that the second parts 112 of the two first mating structures 11 are inserted from top to bottom into the corresponding grooves 221 and fit against the inner wall of the third side wall 2213. In this way, the front panel 1 is detachably set on the front side of the housing 2. Furthermore, the middle of the front panel 1 is matched with the two second mating structures 22 on the housing 2 through the two first mating structures 11. The housing 2 provides sufficient support to the front panel 1 through the matching of the two mating structures and pulls the front panel 1 toward the housing 2, thereby more effectively avoiding the formation of a gap between the front panel 1 and the housing 2.

[0053] In summary, in the preferred embodiment of this utility model, by inserting the first mating structure 11, which is disposed on the side of the front panel 1 facing the cover 2, into the corresponding second mating structure 22 disposed on the front side of the cover 2, and by making at least a portion of the first mating structure 11 and the second mating structure 22 fit together, the cover 2 provides support for the front panel 1 and can also pull the front panel 1 towards it, thereby effectively preventing the formation of a gap between the front panel 1 and the cover 2. By making the first mating structure 11 have a first part 111 and a second part 112 connected to each other, and making the second mating structure 22 have an upwardly open slot, when the front panel 1 is installed onto the cover 2, the second part 112 extends from top to bottom into the groove 221 and fits together with the inner wall of the third side wall 2213 of the groove 221, thereby better supporting and pulling the second part 112 and preventing the formation of a gap between the front panel 1 and the cover 2. By providing reinforcing ribs 113 on the first docking structure 11, the strength of the first docking structure 11 is enhanced, thereby improving the reliability of the fit between the first docking structure 11 and the second docking structure 22.

[0054] In addition, this utility model also provides an air conditioner equipped with the aforementioned indoor air conditioning unit.

[0055] It should be noted that this air conditioner has all the technical effects of the aforementioned indoor air conditioner unit, which will not be repeated here.

[0056] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.

[0057] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features but not others included in other embodiments, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims of this invention, any of the claimed embodiments can be used in any combination.

[0058] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
