Detailed Implementation

[0020] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0021] This application provides a packaging box 100 for use with an indoor air conditioner unit 200 (such as a ducted air conditioner). The indoor air conditioner unit 200 is configured to work in conjunction with a panel embedded in the ceiling. The panel has ventilation openings, and the air outlet of the indoor air conditioner unit 200 is connected to the ventilation openings of the panel to achieve airflow. Therefore, this panel is an air outlet panel. The ventilation openings of the panel and the air outlets of the indoor air conditioner unit 200 need to be aligned to ensure good airflow performance; otherwise, the airflow performance will be greatly reduced, seriously affecting the user experience.

[0022] like Figure 1 As shown, the packaging box 100 includes: a packaging body 1 and a positioning box 2 detachably connected to the packaging body 1. The positioning box 2 is configured to cooperate with the indoor unit 200 of the air conditioner to determine the opening size of the ceiling panel, such as... Figure 3 As shown.

[0023] The packaging box 100 provided in this application embodiment includes a detachable packaging body 1 and a positioning box 2. It can not only serve as packaging for the indoor unit 200 of the air conditioner, but also allow the positioning box 2 to be removed during subsequent installation. The positioning box 2 and the indoor unit 200 of the air conditioner are used to determine the opening size of the ceiling panel, thereby reducing the installation difficulty and complexity of the air conditioning equipment and reducing the need for carpenters to make two or more trips to modify the ceiling size due to inaccurate positioning of the ceiling panel opening.

[0024] The panel can be a standard engineering panel, i.e., a panel with an air outlet grille. The air outlet grille can be connected to the indoor unit of the air conditioner via ductwork or canvas, so a certain gap needs to be reserved between the indoor unit 200 and the ceiling.

[0025] Alternatively, the panel can be an electrically controlled air outlet panel, i.e., an electric panel. Electric panels can be equipped with dampers to guide and sweep air, improving user comfort. Electric panels are relatively thicker, generally exceeding the thickness of the ceiling. Therefore, a certain gap needs to be left between the indoor unit 200 and the ceiling to allow space for the installation of the electric panel.

[0026] In some exemplary embodiments, the positioning box 2 is provided with a first positioning structure, which is configured to cooperate with the indoor unit 200 of the air conditioner to determine the reserved distance between the ceiling and the indoor unit 200 of the air conditioner, such as... Figure 4 As shown.

[0027] In this way, the reserved gap (i.e., positioning in the height direction) and the opening size (i.e., positioning in the length and width direction) between the ceiling and the indoor unit 200 of the air conditioner can be effectively determined. Thus, after the indoor unit 200 of the air conditioner is hoisted, it is convenient for the ceiling workers to quickly and accurately install the ceiling and the subsequent panel installation.

[0028] In some exemplary embodiments, such as Figures 5 to 7 As shown, the positioning box 2 is provided with a connecting part 211 for attaching and fixing to the indoor unit 200 of the air conditioner. The first positioning structure includes: a foldable positioning part 212 connected to the connecting part 211, the foldable positioning part 212 being configured to be able to be in an unfolded state (e.g., Figure 1 and Figure 5 (as shown) and folded state (as shown) Figure 2 , Figure 6 and Figure 7 Switch between )

[0029] like Figure 1 and Figure 5 As shown, with the foldable positioning part 212 in the unfolded state, the foldable positioning part 212 is flush with the connecting part 211. Figure 2 and Figure 7 Since the foldable positioning part 212 is in a folded state, at least a portion of the foldable positioning part 212 protrudes from the connecting part 211 along the thickness direction of the panel to determine the reserved gap between the ceiling and the indoor unit 200 of the air conditioner.

[0030] In this way, when the positioning box 2 is not needed, it can be in the unfolded state, avoiding interference with the indoor air conditioner unit 200 packaged inside the packaging box 100. This also helps reduce the volume of the packaging box 100, facilitating storage and transportation. During subsequent installation, the positioning box 2 can be removed, and the foldable positioning part 212 can be switched to the folded state, then connected to the indoor air conditioner unit 200 to complete the hoisting of the indoor air conditioner unit 200. This is equivalent to pre-installing the panel on the indoor air conditioner unit 200 (using the positioning box 2 to simulate the panel's space occupation), allowing the panel's length, width, and thickness to be determined. Therefore, when ceiling installers install the ceiling later, they can more accurately determine the opening size of the ceiling and the reserved distance between the ceiling and the indoor air conditioner unit 200, thus enabling quick and accurate ceiling installation. When installing the panel later, the positioning box 2 is removed, and then the panel is installed.

[0031] In some exemplary embodiments, such as Figure 1 As shown, the positioning box 2 is provided with a pre-cut line 213, which is partially corresponding to the circumferential edge of the foldable positioning part 212. The pre-cut line 213 can be, but is not limited to, a pinhole line (i.e., a line formed by multiple pinholes spaced apart to facilitate cutting) or a local thinning line (i.e., a line formed by thinning to facilitate cutting).

[0032] Since the foldable positioning part 212 is in the unfolded state, a portion of the circumferential edge of the foldable positioning part 212 is connected to the connecting part 211 by a pre-cut line 213.

[0033] Based on the pre-cut line 213 being cut, the circumferential edge of the foldable positioning part 212 is partially disconnected from the connecting part 211, so that the foldable positioning part 212 can be switched to the folded state.

[0034] When the positioning box 2 is not needed, it can be unfolded and fill the space enclosed by the pre-cut line 213, which helps to improve the sealing of the packaging box 100 and also helps to improve the strength of the positioning box 2. When the positioning box 2 is needed, the circumferential edge of the foldable positioning part 212 is partially cut along the pre-cut line 213, so that the foldable positioning part 212 is bent and deformed, and switched to the folded state.

[0035] In some exemplary embodiments, such as Figure 5 As shown, the pre-cut line 213 includes a first sub-pre-cut line 2131, a second sub-pre-cut line 2132 and a third sub-pre-cut line 2133. The first sub-pre-cut line 2131 and the second sub-pre-cut line 2132 are arranged at intervals and both extend along the length direction of the foldable positioning part 212. The third sub-pre-cut line 2133 extends along the width direction of the foldable positioning part 212.

[0036] The first sub-pre-cut line 2131 and the second sub-pre-cut line 2132 can be symmetrically arranged. The foldable positioning part 212 can be roughly rectangular, with a regular structure, which is convenient for processing and forming, and also convenient for dimensional measurement.

[0037] In some exemplary embodiments, one of the foldable positioning part 212 and the connecting part 211 is provided with a positioning protrusion, and the other is provided with a positioning recess. When the foldable positioning part 212 switches to the folded state, the positioning protrusion is embedded in the positioning recess to restrict the foldable positioning part 212 from switching to the unfolded state.

[0038] This helps improve the reliability of the foldable positioning part 212 in the folded state. Of course, other methods can also be used to ensure the reliability of the foldable positioning part 212 in the folded state, such as fixing it with tape.

[0039] For example, such as Figure 2 and Figure 6 As shown, the positioning protrusion can be, but is not limited to, a positioning flange 2121 on the edge of the foldable positioning part 212. The length of the positioning flange 2121 is greater than the width of the main body of the foldable positioning part 212, such that both ends of the positioning flange 2121 protrude from both ends of the main body of the foldable positioning part 212. The positioning recess includes two positioning openings 216 located at the middle of the length direction of the foldable positioning part 212. The portions of the positioning flange 2121 that protrude from the main body of the foldable positioning part 212 are respectively embedded into the corresponding positioning openings 216, thereby achieving the positioning of the foldable positioning part 212.

[0040] In some exemplary embodiments, the length direction of the foldable positioning part 212 is aligned with the width direction of the vent. The distance between the two ends of the foldable positioning part 212 along its length and the edge of the positioning box 2 can be equal. This makes the structure of the positioning box 2 more regular and easier to process and shape.

[0041] Along the length of the foldable positioning part 212, the minimum distance G between the end of the foldable positioning part 212 and the edge of the positioning box 2 is greater than 200mm. This helps to improve the stability and reliability of the foldable positioning part 212 in the folded state and reduces the risk of deformation of the positioning box 2.

[0042] In some exemplary embodiments, the portion of the foldable positioning part 212 protruding from the connecting part 211 in the folded state has a dimension H greater than 200 mm in the length direction of the foldable positioning part 212.

[0043] This helps improve the stability and reliability of the foldable positioning part 212 in the folded state and reduces the risk of deformation of the positioning box 2.

[0044] In some exemplary embodiments, the foldable positioning part 212 is provided with at least one pre-fold line 2122 (e.g., Figure 7 As shown, the pre-fold line 2122 is configured to guide the foldable positioning part 212 to switch to the folded state. This facilitates the installer to quickly and accurately switch the foldable positioning part 212 to the folded state along the pre-fold line 2122. The pre-fold line 2122 can be, but is not limited to, a pinhole line, a local thinning line, a crease line, a marking line, etc.

[0045] In some exemplary embodiments, such as Figures 1 to 4 As shown, the positioning box 2 includes two independent positioning covers 21, and the two positioning covers 21 have the same dimensions along the width direction of the vent. The dimensions of the two positioning covers 21 along the length direction of the vent may be the same or different.

[0046] like Figure 3 As shown, the two positioning covers 21 are configured to be connected to the indoor unit 200 of the air conditioner and are arranged at intervals along the length of the vent. The opening width of the ceiling to the panel is determined by the dimensions of the two positioning covers 21 along the width of the vent, and the opening length of the ceiling to the panel is determined by the distance between the ends of the two positioning covers 21 that are far apart from each other along the length of the vent.

[0047] In other words, let's designate the two positioning covers 21 as the first positioning cover and the second positioning cover, respectively. The end of the first positioning cover furthest from the second positioning cover corresponds to one end of the panel's length direction, and the end of the second positioning cover furthest from the first positioning cover corresponds to the other end of the panel's length direction. Therefore, the distance between the ends of the first and second positioning covers furthest from each other corresponds to the length of the panel, i.e., the length of the opening between the ceiling and the panel. The dimensions of both the first and second positioning covers along the width of the vent correspond to the width of the panel, i.e., the width of the opening between the ceiling and the panel.

[0048] Thus, the positioning box 2 has a simple structure and is easy to manufacture. Furthermore, after the two positioning covers 21 are removed, they can be individually fitted with the indoor unit 200 of the air conditioner, regardless of the length of the indoor unit 200. Therefore, it can be used for the installation of indoor units 200 of different lengths, improving the versatility of the positioning box 2. Moreover, the manufacturer does not need to provide an additional, larger positioning template to determine the panel opening size, thus helping to reduce costs.

[0049] In some exemplary embodiments, such as Figure 1 As shown, the main packaging body 1 includes a box body 11 and two sealing covers 12. The two sealing covers 12 are arranged along the width direction of the box body 11 and connected to the box body 11. The two positioning covers 21 are arranged along the length direction of the box body 11 and connected to the box body 11.

[0050] In this way, the positioning cover 21 can also cooperate with the sealing cover 12, which helps to improve the sealing performance of the packaging box 100. Furthermore, this solution is equivalent to improving the original packaging box 100 by replacing the two sealing covers 12 with positioning covers 21, which can be removed to serve as positioning boxes 2, without the need for additional positioning boxes 2 or positioning templates, thus reducing costs and increasing efficiency.

[0051] Of course, the two positioning covers 21 can also be located in other positions on the packaging box 100, such as being spaced apart relative to each other along the width direction of the box body 11, or located on the side plate and / or bottom plate of the box body 11.

[0052] In some exemplary embodiments, the positioning cover 21 is connected to the packaging body 1 via a pre-cut line. This allows the positioning cover 21 to be easily removed along the pre-cut line. The pre-cut line can be, but is not limited to, a pinhole line, a local thinning line, or a crease line.

[0053] In some exemplary embodiments, each positioning cover 21 is provided with a connecting portion 211 and a first positioning structure, so that both positioning covers 21 can be used to position the reserved gap between the indoor unit 200 of the air conditioner and the ceiling. Of course, only one positioning cover 21 may be provided with a connecting portion 211 and a first positioning structure.

[0054] In some exemplary embodiments, the positioning cover 21 is provided with a second positioning structure, which is configured to position the positioning cover 21 relative to the indoor unit 200 of the air conditioner. This facilitates the quick and accurate installation of the positioning cover 21 and the indoor unit 200 of the air conditioner.

[0055] In some exemplary embodiments, such as Figure 3 As shown, the second positioning structure includes a first positioning hole 214, which is aligned with the connection hole of the indoor unit 200 and connected by fasteners. This facilitates the positioning cover 21 to be positioned and connected to the indoor unit 200, ensuring the reliable fit between the positioning cover 21 and the indoor unit 200.

[0056] The connection hole of the indoor unit 200 can be an existing functional hole. During installation, the fastener of this connection hole can be removed, the positioning cover 21 can be installed, and then the fastener can be locked. When installing the panel, the fastener and positioning cover 21 can be removed again, and then the fastener can be reset. In this way, there is no need to drill additional holes in the indoor unit 200, nor is it necessary to prepare additional fasteners for fixing the positioning cover 21.

[0057] Alternatively, the connection hole of the indoor unit 200 can be an additional connection hole for connecting the positioning cover 21, which is then secured with additional fasteners. These fasteners and the positioning cover 21 can be removed during subsequent panel installation.

[0058] The number of first positioning holes 214 is not limited, and there can be one or more. Two sets of first positioning holes 214 can be provided at intervals on the positioning cover 21, located on both sides of the foldable positioning part 212. Each set of first positioning holes 214 can have one or more.

[0059] In some exemplary embodiments, such as Figure 3 As shown, the second positioning structure includes a second positioning hole 215, which is aligned with the hanger connection hole of the indoor unit 200 for connecting the hanger rod. The hanger connection hole is located in the hanger lug. There are typically two sets of hanger lugs, each set including multiple lugs.

[0060] The number of second positioning holes 215 is not limited, and there can be one or more. Two sets of second positioning holes 215 can be provided at intervals on the positioning cover 21, located on both sides of the foldable positioning part 212 respectively.

[0061] In some exemplary embodiments, the packaging box 100 is a cardboard box, such as a corrugated cardboard box. The positioning cover 21 is a paper cover, such as a corrugated cardboard cover.

[0062] This application also provides an air conditioning device, including: an indoor air conditioning unit 200, a packaging box 100 as described in any of the above embodiments, and a panel.

[0063] The indoor unit 200 of the air conditioner is equipped with an air outlet. The indoor unit 200 is suspended from the ceiling. The indoor unit 200 is located inside the packaging box 100. The panel is embedded in the ceiling and is used in conjunction with the indoor unit 200. The panel has ventilation openings that communicate with the air outlet.

[0064] The air conditioning equipment provided in this application embodiment has all the above-mentioned beneficial effects because it includes the packaging box 100 of any of the above embodiments, and will not be repeated here.

[0065] In some exemplary embodiments, there are multiple air outlets, including side air outlets and bottom air outlets, and multiple panels, including side panels corresponding to the side air outlets and bottom panels corresponding to the bottom air outlets.

[0066] In this way, air conditioning equipment can have side air outlet mode, bottom air outlet mode, and dual air outlet mode, which helps to enrich the types of air outlet modes of air conditioning equipment and improve the user experience.

[0067] In some exemplary embodiments, the lower panel is further provided with a return air opening, which corresponds to and communicates with the return air vent of the indoor air conditioning unit 200. The packaging box 100 includes at least a positioning box 2 for determining the opening size of the ceiling relative to the lower panel.

[0068] Because the bottom panel integrates both bottom air supply and return functions, it is usually quite large, which can easily lead to problems such as inaccurate positioning of the ceiling opening, affecting air supply. Therefore, at least by using the positioning box 2 to position the ceiling opening of the bottom panel, the installation difficulty of the bottom panel can be effectively reduced.

[0069] Of course, the front panel can also be positioned to locate the ceiling openings using positioning box 2.

[0070] An example is described below.

[0071] The air conditioning unit includes an indoor unit 200, a packaging box 100, a front panel, and a bottom panel. The indoor unit 200 has a side air outlet, a bottom air outlet, and a return air outlet. The front panel has a front ventilation opening and a front damper, while the bottom panel has a bottom ventilation opening, a bottom damper, a return air opening, and a return air grille. The packaging box 100 includes a main packaging body 1 and a positioning box 2. The positioning box 2 is used to determine the opening size of the bottom panel in the ceiling and the reserved distance between the bottom of the indoor unit 200 and the ceiling. Since an access panel is usually reserved at the bottom of the ceiling, the length of the bottom panel will be greater than the length of the indoor unit 200, but the size of the bottom ventilation opening can be aligned with the bottom air outlet.

[0072] like Figure 1 As shown, the main packaging body 1 includes a box body 11 and two sealing covers 12, which are arranged along the width direction of the box body 11 and connected to the box body 11. The positioning box 2 includes two independent positioning covers 21, which are arranged along the length direction of the box body 11 and connected to the box body 11.

[0073] like Figure 2 , Figures 5 to 7 As shown, both positioning covers 21 are provided with a connecting part 211, a first positioning structure, and a second positioning structure. The first positioning structure includes a foldable positioning part 212 connected to the connecting part 211, and the foldable positioning part 212 is configured to switch between an unfolded state and a folded state.

[0074] When the foldable positioning part 212 is in the unfolded state, it is flush with the connecting part 211. When the foldable positioning part 212 is in the folded state, at least a portion of it protrudes from the connecting part 211 along the thickness direction of the panel to determine the reserved gap between the ceiling and the indoor unit 200 of the air conditioner. The positioning cover 21 has a pre-cut line 213, which is partially corresponding to the circumferential edge of the foldable positioning part 212. The pre-cut line 213 includes a first sub-pre-cut line 2131, a second sub-pre-cut line 2132, and a third sub-pre-cut line 2133. The first and second sub-pre-cut lines 2131 and 2132 are spaced apart and both extend along the length direction of the foldable positioning part 212, while the third sub-pre-cut line 2133 extends along the width direction of the foldable positioning part 212. The first and second sub-pre-cut lines 2131 and 2132 are symmetrically arranged.

[0075] One of the foldable positioning part 212 and the connecting part 211 is provided with a positioning protrusion, and the other is provided with a positioning recess. When the foldable positioning part 212 is switched to the folded state, the positioning protrusion is embedded in the positioning recess to restrict the switching of the foldable positioning part 212 to the unfolded state. The positioning protrusion is a positioning flange 2121 on the edge of the foldable positioning part 212, and the positioning recess includes two positioning openings 216 located at the middle of the length direction of the foldable positioning part 212.

[0076] The second positioning structure includes a first positioning hole 214 and a second positioning hole 215. The first positioning hole 214 is positioned and aligned with the connection hole of the indoor unit 200 of the air conditioner and connected by fasteners. The second positioning hole 215 is positioned and aligned with the rod connection hole of the indoor unit 200 of the air conditioner for connecting the rod.

[0077] The positioning cover 21 is rectangular, and the length direction of the positioning cover 21, the length direction of the foldable positioning part 212, and the width direction of the lower air outlet are consistent.

[0078] During installation, remove the two positioning covers 21 from the packaging box 100, cut along the pre-cut line 213, and switch the foldable positioning part 212 to the folded state. Then align the second positioning hole 215 of the positioning cover 21 with the hanging rod connection hole of the air conditioner indoor unit 200, align the first positioning hole 214 of the positioning cover 21 with the connection hole of the air conditioner indoor unit 200, and tighten the screws to connect the positioning cover 21 to the air conditioner indoor unit 200. Figure 3 and Figure 4As shown. After the two positioning covers 21 are connected to the bottom ends of the indoor unit 200, and then the indoor unit 200 is hoisted to the ceiling, the two positioning covers 21 simulate the state after the bottom panel is installed, which is equivalent to the pre-installation of the bottom panel. Therefore, the length C and width A of the space occupied by the two positioning covers 21 can determine the length and width of the opening in the ceiling. The protrusion height B of the foldable positioning part 212 of the positioning cover 21 can determine the reserved distance between the indoor unit 200 and the ceiling. A certain design deviation is allowed according to the design. That is, the length C and width A of the space occupied by the two positioning covers 21 can be equal to or approximately equal to the length and width of the opening in the ceiling; the protrusion height B of the foldable positioning part 212 can be equal to or approximately equal to the reserved distance between the indoor unit 200 and the ceiling.

[0079] Therefore, the workers installing the ceiling can install it according to the positioning results. After the ceiling is installed, the workers installing the panels will remove the two positioning covers 21 and then install the lower panel, which can be locked to the indoor unit 200 of the air conditioner with fasteners.

[0080] Please refer to the following: Figure 8 and Figure 9 As shown, the relevant dimensions of the two positioning covers 21 after they are connected to the indoor unit 200 of the air conditioner are as follows: A: This refers to the width of the opening that needs to be made in the ceiling for the bottom panel. It is generally determined based on the actual design, i.e., the actual width of the bottom panel.

[0081] B: This is the reserved gap between the bottom surface of the indoor unit 200 and the upper surface of the ceiling, which is equal to or approximately equal to the thickness of the lower panel inside the ceiling when the lower panel is locked to the indoor unit 200.

[0082] C: This is the length of the hole that needs to be made in the ceiling for the lower panel. It is generally determined based on the actual design, i.e., based on the actual length of the lower panel.

[0083] D1 and D2: These are the distances between the center of the second positioning hole 215 and the edge of the positioning cover 21, which should be determined according to actual requirements.

[0084] E1 and E2: The distance between the center of the first positioning hole 214 and the edge of the positioning cover 21. The number of the first positioning holes 214 can be two or more on one side. To ensure the fixing strength, it can be confirmed according to the actual needs of the connection holes reserved in the indoor unit of the air conditioner 200.

[0085] F1 and F2: These represent the lengths by which the positioning cover 21 folds inwards into the main packaging body 1, i.e., the dimensions of the positioning cover 21 along the length of the main packaging body 1. For aesthetic and symmetrical design, F1 and F2 are taken as their maximum values. If there is a large difference between F1 and F2, and there is no need for symmetry, the values ​​can be determined according to the actual situation. It is recommended that A:F1≥1:1 and A:F2≥1:1.

[0086] G: The distance from the end of the foldable positioning part 212 along its length to the edge of the positioning cover 21 is recommended to be greater than 200mm.

[0087] H: The length of the portion of the foldable positioning part 212 that protrudes from the connecting part 211 in the folded state along the width direction of the lower vent, which is recommended to be greater than 200mm.

[0088] J: The length of the foldable positioning part 212 is calculated according to actual requirements, J=A-2G.
