Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to an air conditioner cabinet and an air conditioner. Background Art

[0002] In cabinet air conditioners, a duct assembly is typically installed downstream of the blower motor and fan. This assembly can include guide vanes or other components with a rectifying function. When installing the duct assembly on the duct mounting plate, the entire duct wall of the duct assembly must mate with a full-circle annular flange on the front surface of the duct mounting plate.

[0003] During the assembly process, the duct mounting plate needs to be laid flat, and then the duct wall needs to be installed on the outer or inner periphery of the annular flange from top to bottom. However, if the fit between the two is too tight, it will be difficult to insert the two parts during installation because the two parts cannot completely match the designed size and shape. If the fit between the two is too loose, a large gap will be generated around the entire rear end of the duct wall, resulting in a large amount of air leakage. Utility Model Content

[0004] The first aspect of the present invention aims to provide an air-conditioning cabinet unit to solve the technical problem of the difficulty in installing on the existing air duct wall.

[0005] The first aspect of the present invention provides an air conditioning cabinet, comprising an air duct mounting plate and an air duct assembly, wherein the air duct assembly has an air duct wall;

[0006] The air duct mounting plate has a first sealing flange and a second sealing flange. In the assembled state, the outer side wall of the first sealing flange is sealed to the mounting end of the air duct wall, and the inner side wall of the second sealing flange is sealed to the mounting end.

[0007] The first sealing flange and the second sealing flange form an insertion gap, and the insertion gap is configured to accommodate the installation end of the air duct wall.

[0008] The beneficial effects brought by the utility model air conditioning cabinet are:

[0009] By providing a first sealing flange and a second sealing flange, the first sealing flange can be sealed with the mounting end from the inner side of the mounting end, and the second sealing flange can be sealed with the mounting end from the outer side of the mounting end. Moreover, compared with the existing solution in which the annular ridge of the entire circumference is nominally connected to the mounting end but cannot ensure whether it is sealed, this sealing can ensure that sealing is indeed achieved at the mating position, so that the area that is not directly sealed with the mounting end by the first sealing flange and the second sealing flange is only controlled in the area where the insertion gap is located, thereby reducing the scope of possible air leakage.

[0010] Moreover, an insertion gap is provided between the corresponding ends of the first sealing flange and the second sealing flange for the installation end of the duct wall to be inserted, so that the duct wall does not need to overcome the large fitting resistance with the sealing ridge during the process of being placed on the duct mounting plate, thereby reducing the difficulty of operation.

[0011] In an optional technical solution, the insertion gap is configured to allow the air duct wall to move from the first sealing flange to the second sealing flange.

[0012] By configuring the insertion gap to accommodate movement of the duct wall, the mounting end can be first placed over the outside of the first sealing flange during assembly. During this process, the inner sidewall of the mounting end and the outer sidewall of the first sealing flange do not come into contact, allowing a portion of the mounting end to be inserted into the insertion gap. Furthermore, as the duct wall moves toward the duct mounting plate, the inner sidewall of the mounting end and the inner sidewall of the second sealing flange do not come into contact, eliminating the need to overcome friction caused by dimensional errors between the two, significantly reducing the labor load during assembly. The duct wall can then be moved a short distance toward the second sealing flange to mate with the mounting end, thereby also achieving alignment with the first sealing flange. This eliminates the need to forcibly squeeze the duct wall over the outer side of the annular flange of the duct mounting plate, ensuring a reliable direct sealing area and improving assembly efficiency.

[0013] In an optional technical solution, the first sealing flange includes a first sealing fitting portion, and the outer side walls of the first sealing fitting portion are sealed and fitted to the inner side wall of the air duct wall; the second sealing flange includes a second sealing fitting portion, and the inner side walls of the second sealing fitting portion are sealed and fitted to the inner side wall of the air duct wall.

[0014] The first sealing fitting portion and the second sealing fitting portion are respectively sealed to the inner wall and the outer wall of the air duct wall to ensure that the air duct wall and the first sealing flange and the sealing flange have sufficient sealing area, thereby improving the reliability of the seal.

[0015] In an optional technical solution, both the first sealing fitting portion and the second sealing fitting portion have openings, and the openings of the first sealing fitting portion and the second sealing fitting portion are opposite to each other.

[0016] With such an arrangement, the contact areas between the first sealing contact portion and the second sealing contact portion and the mounting end can be increased, thereby improving the sealing performance of the air duct wall.

[0017] In an optional technical solution, the second sealing flange further includes a first extension portion, and the first extension portion extends outward or forward from an end portion of the second sealing fitting portion.

[0018] By setting the first extension part, on the one hand, the air duct wall can be guided early when the mounting end moves toward the second sealing flange. On the other hand, the first extension part can be set outside the mounting end to hinder the airflow from flowing outward from this part of the air duct wall.

[0019] In an optional technical solution, the inner side wall of the first extension portion is a plane, and the inner side wall of the first extension portion is tangent to the end portion of the inner side wall of the second sealing fitting portion to which it is connected.

[0020] By setting the inner side wall of the first extension portion to be a plane and making the inner side wall of the first extension portion tangent to the end of the second sealing fitting portion, the mounting end can be smoothly guided into the second sealing fitting portion, thereby improving the convenience of operation.

[0021] In an optional technical solution, the central angle of the second sealing portion is less than 180°.

[0022] By setting the central angle of the second sealing portion to be less than 180°, the spacing between the free ends of the first extensions can be increased, thereby widening the insertion gap and making it easier to insert the mounting end between the first extensions. Furthermore, before the mounting end contacts the second sealing portion, i.e., before the mounting end moves into position, it can be disengaged from the first extensions, at least avoiding contact with both opposing first extensions. This reduces resistance to movement of the mounting end between the first extensions.

[0023] In an optional technical solution, the air duct wall is a cylindrical structure, and the first sealing fitting portion and the second sealing fitting portion are both arc-shaped.

[0024] The duct wall is a cylindrical structure, which is easy to process and helps ensure that the airflow is evenly affected by the duct wall at different circumferential angles when moving in the duct wall, thereby reducing airflow energy loss.

[0025] In an optional technical solution, the first sealing flange is located above the second sealing flange.

[0026] By placing the first sealing flange above the second sealing flange, the weight of the duct assembly can be primarily borne by the first and second sealing flanges. Furthermore, the weight of the duct assembly exerts pressure on the first and second sealing flanges, causing them to deform, increasing their contact area with the duct wall and improving sealing.

[0027] In an optional technical solution, the mounting end is fixedly connected to a sealing member, and the sealing member is configured to seal the insertion gap after the air duct wall is installed in place.

[0028] By arranging a sealing member to be fixedly connected to the mounting end, the insertion gap can be blocked, thereby achieving full circumferential sealing and improving the sealing performance between the air duct wall and the air duct mounting plate.

[0029] The second aspect of the present invention aims to provide an air conditioner to solve the technical problem of difficulty in installing on the air duct wall.

[0030] The air conditioner provided in the second aspect of the present invention comprises an air conditioner outdoor unit and any one of the above-mentioned air conditioner cabinet units, wherein the air conditioner outdoor unit is connected to the air conditioner cabinet unit via a refrigerant connecting pipe.

[0031] By arranging the above-mentioned air-conditioning cabinet in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned air-conditioning cabinet, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example 1:

[0043] Figure 1 This is a schematic diagram of the structure of the air conditioning cabinet provided in Example 1 of the present utility model; Figure 2 This is a schematic diagram of the structure of the separated air duct components of the air conditioning cabinet provided in the first embodiment of the present invention; Figure 3 A schematic diagram of the installation process of the air duct wall of the air conditioner cabinet provided in the first embodiment of the present invention; Figure 4 This is a structural diagram of the air duct assembly of the air conditioner cabinet provided by the first embodiment of the present invention, separated and viewed from another direction; Figure 1-Figure 4 As shown, the air conditioning cabinet provided by the first embodiment of the present invention includes an air duct mounting plate 100 and an air duct assembly 200 , and the air duct assembly 200 has an air duct wall 210 ;

[0044] The air duct mounting plate 100 has a first sealing flange 110 and a second sealing flange 120. The first sealing flange 110 is located inside the air duct wall 210. In the assembled state, the outer wall of the first sealing flange 110 is sealed to the mounting end of the air duct wall 210, and the inner wall of the second sealing flange 120 is sealed to the mounting end.

[0045] The first sealing flange 110 and the second sealing flange 120 form an insertion gap 130 , and the insertion gap 130 is configured to accommodate the installation end of the air duct wall 210 .

[0046] By providing the first sealing flange 110 and the second sealing flange 120, the first sealing flange 110 and the second sealing flange 120 are respectively sealed with the mounting end from the inner side and the outer side of the mounting end. Moreover, compared with the existing solution in which the annular ridge of the entire circumference is nominally connected to the mounting end and whether it is sealed cannot be ensured, this sealing can ensure that sealing is indeed achieved at the mating position, so that the area that is not directly sealed with the mounting end by the first sealing flange 110 and the second sealing flange 120 is only controlled in the area where the insertion gap 130 is located, thereby reducing the scope of possible air leakage.

[0047] Moreover, an insertion gap 130 is provided between the corresponding ends of the first sealing flange 110 and the second sealing flange 120 for the installation end of the duct wall 210 to be inserted, so that the duct wall 210 does not need to overcome the large fitting resistance with the sealing flange during the process of being placed on the duct mounting plate 100, thereby reducing the difficulty of operation.

[0048] It should be noted that the first sealing flange 110 and the second sealing flange 120 being provided on the air duct mounting plate 100 is not limited to being provided directly on the plate of the air duct mounting plate 100 itself, but may also include situations where the first sealing flange 110 and the second sealing flange 120 are provided on other parts fixedly connected to the air duct mounting plate 100. Specifically, in this embodiment, the air duct wall 210 is provided with air guide vanes 220, and the installation of the air duct wall 210 on the air duct mounting plate 100 also completes the mechanical installation process of the air guide vanes 220.

[0049] In this embodiment, the insertion gap 130 is adapted for the installation end of the air duct wall 210 to be inserted, which means that the width of the insertion gap 130 is correspondingly greater than or equal to the thickness of the portion of the installation end inserted into the insertion gap 130 .

[0050] like Figure 3 As shown, optionally, the insertion gap 130 is configured to allow the duct wall 210 to move from the first sealing flange 110 to the second sealing flange 120 .

[0051] The insertion gap 130 is set to allow the air duct wall 210 to move. During the assembly process, the mounting end is first placed on the outside of the first sealing flange 110. The inner side wall of the mounting end and the outer side wall of the first sealing flange 110 do not contact each other, so that a part of the mounting end is inserted into the insertion gap 130. Figure 3As shown, the central angle of the first sealing contact portion 111 is less than 180°. During the movement of the duct wall 210 toward the duct mounting plate 100, the inner sidewall of the mounting end and the outer sidewall of the second sealing flange 120 do not come into contact. This means there is no need to overcome friction caused by dimensional errors between the two, significantly reducing the labor load during assembly. The mounting end is then moved a short distance toward the second sealing flange 120 to engage the second sealing flange 120. This eliminates the need to forcibly squeeze the duct wall 210 against the outer side of the annular flange of the duct mounting plate 100, ensuring a reliable direct sealing area and improving assembly efficiency.

[0052] like Figure 1-Figure 3 As shown, optionally, the first sealing flange 110 includes a first sealing fitting portion 111, and the outer side walls of the first sealing fitting portion 111 are sealed and fitted to the inner side wall of the air duct wall 210; the second sealing flange 120 includes a second sealing fitting portion 121, and the inner side walls of the second sealing fitting portion 121 are sealed and fitted to the inner side wall of the air duct wall 210.

[0053] The first sealing fitting portion 111 and the second sealing fitting portion 121 are respectively sealed to the inner wall and the outer wall of the air duct wall 210 to ensure that the air duct wall 210 and the first sealing flange 110 and the second sealing flange 120 have sufficient sealing area, thereby improving the reliability of the seal.

[0054] Specifically, in this embodiment, the central angle corresponding to the first sealing portion 111 is less than 180°, and the central angle corresponding to the second sealing portion 121 is less than or equal to 180°. The air conditioning cabinet in this embodiment can be an air conditioning cabinet with an axial flow fan. In this embodiment, the central angle of the first sealing portion 111 can be in the range of greater than or equal to 150° to less than 180°, and further, can be 160°, 170°, 165°, or 175°.

[0055] like Figure 1-Figure 3 As shown, optionally, the first sealing bonding portion 111 and the second sealing bonding portion 121 both have openings, and the openings of the first sealing bonding portion 111 and the second sealing bonding portion 121 are opposite to each other.

[0056] With such a configuration, the contact areas between the first sealing contact portion 111 and the second sealing contact portion 121 and the mounting end can be increased, thereby improving the sealing performance of the air duct wall 210 .

[0057] like Figure 3 As shown, optionally, the air duct wall 210 is a cylindrical structure, and the first sealing fitting portion 111 and the second sealing fitting portion 121 are both arc-shaped structures.

[0058] The air duct wall 210 is a cylindrical structure, which is easy to process and helps ensure that the airflow is evenly affected by the air duct wall 210 at different angles in the circumferential direction when moving in the air duct wall 210, thereby helping to reduce airflow energy loss.

[0059] Of course, in other implementations, if the mounting end is not circular, but rather elliptical, for example, the first sealing and affixing portion 111 and the second sealing and affixing portion 121 may also be elliptical arcs that match the circular arc. Alternatively, the mounting end may be a square with four corners facing up, down, left, and right, or a regular octagonal or hexagonal structure with corners facing up, down, left, and right.

[0060] like Figure 2-Figure 4 As shown, optionally, the second sealing flange 120 also includes a first extension portion 122, which extends from the end of the second sealing fitting portion 121, and the minimum spacing between the inner wall of the first extension portion 122 and the outer wall of the first sealing fitting portion 111 is greater than or equal to the thickness of the mounting end.

[0061] By setting the first extension portion 122, on the one hand, the air duct wall 210 can be guided in advance when the mounting end moves toward the second sealing flange 120. On the other hand, the first extension portion 122 can be set outside the mounting end to hinder the airflow from this part of the air duct wall 210 to flow outward.

[0062] The first extension portion 122 extends from the end of the second sealing portion 121. In a direction away from the end of the second sealing portion 121, the two first extension portions 122 can be arranged in parallel or with a gradually increasing distance therebetween.

[0063] Of course, in another implementation, the second sealing flange 120 may not be provided with the first extension portion 122 so as not to hinder the first sealing fitting portion 111, the second sealing fitting portion 121 from directly fitting with the mounting end to achieve a sealing effect.

[0064] like Figure 2-Figure 4 As shown, optionally, the free ends of the two first extension portions 122 and the two ends of the first sealing flange 110 are collinearly arranged.

[0065] Since the inner side wall of the mounting end can cooperate with the first sealing fitting portion 111 of the first sealing flange 110 to achieve sealing, and the free end of the first extension portion 122 is set to be collinear with the two ends of the first sealing flange 110, there is no need to set the first extension portion 122 on the outside of the overlapping area between the inner side wall of the mounting end and the first sealing fitting portion 111 of the first sealing flange 110, thereby reducing material consumption.

[0066] Since the first extension portion 122 extends from the end of the second sealing portion 121, the end of the first extension portion 122 facing away from the second sealing portion 121 is the free end of the first extension portion 122. In this embodiment, the free ends of the two first extension portions 122 and the two ends of the first sealing flange 110 are collinearly disposed.

[0067] like Figure 2-Figure 4 As shown, optionally, the inner side wall of the first extension portion 122 is a plane, and the inner side walls of the first extension portion 122 are respectively tangent to the end portions of the inner side walls of the second sealing and fitting portions 121 to which they are connected.

[0068] By setting the inner side wall of the first extension portion 122 to be a plane and making the inner side wall of the first extension portion 122 tangent to the end of the second sealing fitting portion 121, the installation end can be smoothly guided into the second sealing fitting portion 121, thereby improving the convenience of operation.

[0069] like Figure 3 As shown, optionally, the central angle of the second sealing portion 121 is less than 180°.

[0070] By setting the central angle of the second sealing portion 121 to be less than 180°, the spacing between the free ends of the first extensions 122 can be increased, thereby increasing the width of the insertion gap 130 and making it easier for the mounting end to be inserted between the first extensions 122. Furthermore, before the mounting end contacts the second sealing portion 121, that is, before the mounting end moves into position, it can be disengaged from the first extensions 122, at least avoiding contact with both of the two oppositely disposed first extensions 122, thereby reducing resistance to movement of the mounting end between the first extensions 122.

[0071] Specifically, in this embodiment, the central angle of the second sealing contact portion 121 may be in the range of greater than or equal to 150° to less than 180°, and further, may be 160°, 170°, 165°, or 175°.

[0072] Of course, in another implementation, the central angle of the second sealing affixed portion 121 can also be 180°, then the two first extensions 122 are arranged in parallel, and the distance between the two first extensions 122 is the diameter of the outer wall of the mounting end. That is, when the mounting end moves from the first sealing flange 110 to the second sealing flange 120, there is a risk of friction between the mounting end and the first extension 122. However, this arrangement can still ensure that the mounting end can be moved into place. In addition, in this case, the first sealing flange 110 can be entirely the first sealing affixed portion 111, and the first sealing affixed portion 111 is a semicircular arc, that is, its central angle is 180°. However, this arrangement also allows the mounting end to be sealed over its entire 360° circumference, thereby improving sealing. Moreover, those skilled in the art should know that in this case, the shorter the length of the first extension 122, the shorter the distance over which this frictional resistance exists during movement.

[0073] like Figure 1-Figure 4 As shown, optionally, the first sealing flange 110 is located above the second sealing flange 120 .

[0074] By placing the first sealing flange 110 above the second sealing flange 120, the first and second sealing flanges 110, 120 can primarily bear the weight of the duct assembly 200. Furthermore, the weight of the duct assembly 200 exerts pressure on the first and second sealing flanges 110, 120, causing them to deform, thereby increasing their contact area with the duct wall 210 and improving sealing performance.

[0075] In this embodiment, the mounting end can also be fixedly connected to the first sealing flange 110 via screws. Since the weight is primarily borne by the first sealing flange 110 and the second sealing flange 120, the screw can primarily bear the torque to prevent the air duct assembly 200 from tipping over. Of course, the mounting end can also be fixedly connected to the second sealing flange 120 via screws.

[0076] Optionally, the mounting end is fixedly connected to a sealing member 140 , and the sealing member 140 is configured to seal the insertion gap 130 after the air duct wall 210 is installed in place.

[0077] By providing a seal 140 fixedly connected to the mounting end, the insertion gap 130 can be sealed, thereby achieving full circumferential sealing and improving the sealing performance between the air duct wall 210 and the air duct mounting plate 100.

[0078] Specifically, a sealing member 140, such as sponge or rubber, can be attached to the space of the duct wall 210 opposite the insertion gap 130. Furthermore, the sealing member 140 can be attached to the outside of the duct wall 210. Because the central angle of the second sealing portion 121 is less than 180° and the first extension 122 is tangential to the second sealing portion 121, the two first extensions 122 are larger on the outside and smaller on the inside. Therefore, as the duct wall 210 approaches the second sealing portion 121, the sealing member 140 can be gradually clamped by the first extensions 122 and secured between the first extension 122 and the outer wall of the duct wall 210.

[0079] Of course, in other implementations, the seal 140 may not be provided. Due to the above structure, the leakage location can be controlled to a smaller area where the insertion gap 130 is located, so the air leakage amount can be completely controlled within an acceptable range, and thus the sealing requirement can be met without the seal 140.

[0080] In addition to extending the first extension portion 122 at the end of the second sealing fitting portion 121 to use the space between the first extension portion 122 and the mounting end to clamp the seal 140, the second extension portion 122 may also be extended at the end of the first sealing fitting portion 111. The second extension portion extending from the end of the first sealing fitting portion 111 should obviously also be located within the inner side wall of the mounting end. At the same time, when the mounting end moves toward the second sealing flange 120, it will not interfere with the movement of the mounting end. For example, the second extension portion may extend from the end of the first sealing fitting portion 111 along the inner side wall of the mounting end. Figure 3 The extending direction shown is more specifically the extending direction Figure 3 The first extension portion 122 is shown to be parallel, and the length of the second extension portion may also be the same as that of the first extension portion 122 . The second extension portion and the inner side wall of the mounting end may be used to clamp the sealing member 140 .
