Description

[Technical Field]

[0001] This application relates to the field of range hoods, and more particularly to foam bases for packaging range hoods. [Background Technology]

[0002] The existing foam packaging for range hoods has a very simple structure, and its load-bearing and impact resistance needs to be improved. In particular, as range hoods become increasingly thinner, damage to the range hood body frequently occurs during long-distance transportation due to the unsatisfactory load-bearing and impact resistance of the foam packaging.

[0003] Unless there is sufficient evidence to support it, the prior art described herein does not imply an admission that such prior art was known to a person skilled in the art prior to the filing date of this application. [Summary of the Invention]

[0004] One objective of this application is to provide an improved range hood assembly and a foam base for packaging a range hood, addressing at least one of the above-mentioned technical problems and / or other possible technical problems not mentioned in this application.

[0005] According to a first aspect of this application, embodiments of this application provide a foam base for packaging a range hood, comprising a receiving groove, wherein a long strip-shaped support extends upward from the bottom of the first groove wall to form a support member; the long strip-shaped support member is lower than the first groove wall; the long strip-shaped support member is configured to support a first end edge of the range hood; the first groove wall is configured to stop the first end edge; the long strip-shaped support member is provided with a plurality of notches. It should be noted that "a plurality of notches" can be understood as two or more notches.

[0006] The elongated support member has several notches. Therefore, while effectively supporting the first edge of the range hood, the elongated support member also reduces the contact area between the first edge of the range hood and the elongated support member, reducing stress concentration and minimizing or avoiding the risk of the range hood falling and deforming during transportation.

[0007] In one or more embodiments, the notch in the width direction of the foam base does not penetrate the elongated support member. This reduces stress concentration while ensuring the strength of the elongated support member, reducing or avoiding the risk of deformation from falls during transport of the range hood.

[0008] In one or more embodiments, the notch extends through the top wall of the elongated support member, forming a top opening. This helps reduce stress concentration and minimizes or avoids the risk of the range hood falling and deforming during transportation.

[0009] In one or more embodiments, the notch extends through the inner wall of the elongated support member, forming a sidewall opening. This helps reduce stress concentration and minimizes or avoids the risk of deformation from falls during transport of the range hood.

[0010] In one or more embodiments, the top opening and side wall opening corresponding to the same notch are interconnected. This helps to reduce stress concentration and reduce or avoid the risk of deformation from falling during the transportation of the range hood.

[0011] In one or more embodiments, the notches are arranged sequentially along the length of the foam base. This helps to reduce stress concentration and minimize or avoid the risk of deformation from falls during transport of the range hood.

[0012] In one or more embodiments, each of the notches is generally serrated. This helps to reduce stress concentration and reduce or avoid the risk of deformation from falls during the transportation of the range hood.

[0013] In one or more embodiments, a gap is provided between the elongated support member and the first groove wall. This reduces or avoids interference between the elongated support member and the first groove wall, improving structural stability.

[0014] According to a second aspect of this application, embodiments of this application provide a range hood assembly, including a range hood and a foam base as described in any of the above claims; the range hood includes a housing and a smoke collection hood; a hanging hole is provided on the top edge of the rear wall of the housing; the hanging hole is located above the top wall of the housing; the housing is placed in the receiving groove of the foam base; and an elongated support member supports the top edge of the rear wall of the housing. Thus, the elongated support member effectively supports the top edge of the rear wall of the housing while reducing the contact area between the top edge of the rear wall of the housing and the elongated support member, reducing stress concentration, and reducing or avoiding the risk of drop and deformation during the transportation of the range hood.

[0015] In one or more embodiments, a foam top cover is included; the foam top cover and the foam base are spaced apart to form a receiving space suitable for accommodating and placing the range hood.

[0016] It should be noted that, unless otherwise specified, directional expressions such as "upward," "above," "downward," and "from bottom to top" appearing in this application are based on the usual usage state of the corresponding objects.

[0017] It should be noted that the terms "first" and "second" appearing in this specification are for descriptive purposes only and are not used to indicate relative importance; moreover, they do not define the number of features they define; furthermore, they do not define the logical or sequential relationship between the features they define.

[0030] This application proposes an embodiment of a foam base for packaging range hoods, such as... Figure 1 and 2 As shown. This embodiment of the foam base 1 for packaging a range hood is integrally molded from foam material. This embodiment of the foam base 1 for packaging a range hood has a receiving groove. The receiving groove has a first groove wall 5 and a second groove wall 6 facing each other. The receiving groove also has a left groove wall and a right groove wall facing each other. The first groove wall 5, the right groove wall, the second groove wall 6, and the left groove wall are sequentially connected to form the side walls of the receiving groove. This foam base 1 is used to hold the range hood and provides protection for its transportation. Specifically, the range hood is placed inside the receiving groove of the foam base 1. First, the foam base 1 is placed so that the opening of the receiving groove of the foam base 1 faces upwards, approximately as shown. Figure 1 As shown, so that the range hood can be placed from top to bottom into the receiving groove of the foam base 1.

[0031] In this embodiment of the foam base 1 used for packaging range hoods, a long strip-shaped support member 2 extends upward from the bottom of the first groove wall 5 at the groove bottom, such as... Figures 1 to 4 As shown. A long strip-shaped support member 2 is disposed near the first groove wall 5. The long strip-shaped support member 2 extends from the left groove wall of the receiving groove to the right groove wall of the receiving groove.

[0032] In addition to the elongated support member 2, the bottom of the groove in this embodiment of the foam base 1 for packaging the range hood also has a hollow support structure, such as... Figure 1 , 2 As shown in Figure 4, the elongated support member 2 and the perforated support structure work together to support the range hood placed within the receiving groove of the foam base 1. The perforated support structure helps reduce the amount of foam used, thereby lowering manufacturing costs.

[0033] The elongated support member 2 is lower than the first groove wall 5, such as... Figure 1 and 2 As shown. In other words, in the height direction of the foam base 1, the elongated support 2 is lower than the first groove wall 5. It should be noted that, with Figure 1 Using the xyz rectangular coordinate system as a reference, the x-axis direction is approximately the length direction of the foam base 1, the y-axis direction is approximately the width direction of the foam base 1, and the z-axis direction is approximately the height direction of the foam base 1.

[0034] The first groove wall 5 extends along the length of the foam base 1. The elongated support 2 also extends along the length of the foam base 1. In other words, both the elongated support 2 and the first groove wall 5 extend from the left groove wall to the right groove wall, as shown below. Figure 1 and 2 As shown.

[0035] The elongated support member 2 is configured to support the first end edge of the range hood. The first groove wall 5 is configured to stop the first end edge; that is, when the elongated support member 2 supports the first end edge of the range hood, the first groove wall 5 stops the first end edge. In other words, when the range hood is placed into the receiving groove, the elongated support member 2 supports the first end edge of the range hood, and the first groove wall 5 stops the first end edge, as shown below. Figure 3 As shown.

[0036] The elongated support member 2 is positioned adjacent to and lower than the first groove wall 5, thus forming a stepped structure together with the first groove wall 5. The top wall of the elongated support member 2 corresponds to the tread surface of this stepped structure, and the inner wall of the first groove wall 5 corresponds to the kick surface of this stepped structure. The tread surface and the kick surface of this stepped structure form a 90° angle. This stepped structure is used to support and limit the first edge of the range hood.

[0037] The first groove wall 5 and the second groove wall 6 are arranged facing each other and both extend along the length of the foam base 1, such as Figure 1 As shown. When the range hood is placed into the receiving groove, the first groove wall 5 stops the top of the range hood, and the second groove wall 6 stops the bottom of the range hood. Therefore, under the combined action of the first groove wall 5 and the second groove wall 6, the range hood placed in the receiving groove will not move in the width direction of the foam base 1. Figure 3 As shown, this provides protection for the transport of the range hood. The top of the range hood, stopped by the first groove wall 5, is the top of the range hood's casing. The bottom of the range hood, stopped by the second groove wall 6, is the bottom of the range hood's smoke collection hood.

[0038] The left and right tank walls are set facing each other, such as... Figure 1As shown. When the range hood is placed into the receiving groove, the left groove wall stops the left side of the range hood, and the right groove wall stops the right side of the range hood. Therefore, under the combined action of the left and right groove walls, the range hood placed in the receiving groove will not move along the length of the foam base 1, as shown. Figure 3 As shown, this provides protection for the transport of the range hood. The left side of the range hood, blocked by the left wall, includes the left side of the range hood housing and the left side of the range hood's smoke collection hood. The right side of the range hood, blocked by the right wall, includes the right side of the range hood housing and the right side of the range hood's smoke collection hood.

[0039] The long strip support 2 has several notches 3, such as Figure 1 , 2 As shown in Figure 4. In this embodiment, there are a total of six notches 3. In the width direction of the foam base 1, none of the notches 3 penetrate the elongated support member 2. Therefore, while the elongated support member 2 effectively supports the first edge of the range hood, it also reduces the contact area between the first edge of the range hood and the elongated support member 2, reducing stress concentration and reducing or avoiding the risk of deformation due to falling during transport. Preferably, the notch 3 penetrates two-thirds or less of the thickness of the elongated support member 2; or, the notch 3 penetrates between two-thirds and one-third of the thickness of the elongated support member 2.

[0040] Each notch 3 penetrates the top wall of the elongated support member 2, forming a top opening. Each notch 3 also penetrates the inner side wall 4 of the elongated support member 2, forming a side wall opening. The top opening and side wall opening corresponding to the same notch 3 are interconnected, as shown below. Figure 1 and 2 As shown. Each notch 3 has a serrated shape. Each notch 3 is arranged sequentially along the length of the foam base 1.

[0041] A gap is provided between the elongated support member 2 and the first groove wall 5, such as... Figure 1 and 2 As shown. In the width direction of the foam base 1, the width of the gap between the elongated support 2 and the first groove wall 5 is less than 1 cm.

[0042] This application also proposes an embodiment of a range hood assembly, including a range hood and the aforementioned foam base 1 embodiment for packaging the range hood, as shown below. Figure 3 and 4 As shown. During assembly, first place the foam base 1 with the opening of the receiving groove of the foam base 1 facing upwards, so that the range hood can be placed into the receiving groove of the foam base 1 from top to bottom.

[0043] The range hood includes a housing 8 and a smoke collection hood 9. A centrifugal fan is installed inside the housing 8. The housing 8 and the smoke collection hood 9 are connected together. The shape and size of the receiving groove match the shape and size of the rear wall of the range hood. Thus, the receiving groove is suitable for the rear wall of the range hood to be fitted into it, such as... Figure 3 As shown.

[0044] In operation, the range hood is suspended on the kitchen wall, with the casing 8 and the smoke collection hood 9 arranged sequentially from top to bottom, the smoke collection hood 9 suspended below the casing 8. When the centrifugal fan is running, it generates negative pressure, forming an airflow of oily fumes. The oily fumes first flow into the smoke collection hood 9, then into the casing 8, then out of the range hood and into the exhaust duct, and finally into the common flue.

[0045] A hanging hole 14 is provided on the top edge 13 of the rear wall of the housing 8. The hanging hole 14 is suitable for use with wall hooks in the kitchen to hang the range hood on the kitchen wall. The hanging hole 14 is located at the top of the top wall of the housing 8, such as... Figure 5 As shown. The electrical box 11 is fixed to the top wall of the housing 8. An exhaust port 12 is provided on the top wall of the housing 8. The exhaust pipe of the centrifugal fan is connected to the lower side of this exhaust port 12. A duct seat is connected to the upper side of this exhaust port 12. The duct seat is used to connect and fix one end of the smoke exhaust pipe. The other end of the smoke exhaust pipe is connected to the common flue.

[0046] It should be noted that the range hood assembly embodiment proposed in this application shows the packaging state of the range hood during transportation. The rear wall of the range hood faces downwards and is placed in the receiving groove of the foam base 1. Specifically, the rear wall of the housing 8 is arranged horizontally and placed downwards into the receiving groove, as shown below. Figure 3 and 4 As shown, the top edge 13 of the rear wall of the housing 8 rests on the top wall of the long strip support 2.

[0047] The casing 8 and the smoke hood 9 are of a single integrated structure, such as... Figure 3 and 4 As shown. In other words, the range hood body is placed in the receiving groove of the foam base 1. The long strip support 2 supports the top edge 13 of the rear wall of the housing 8.

[0048] When the range hood is placed in the receiving groove of the foam base 1, the elongated support 2 supports the first edge of the range hood from bottom to top. This first edge is the top edge 13 of the rear wall of the housing 8. In other words, the elongated support 2 supports the top edge 13 of the rear wall of the housing 8 from bottom to top, as... Figure 3 As shown.

[0049] When the range hood is placed in the receiving groove of the foam base 1, the hollow support structure supports the rear wall of the range hood from bottom to top. At this time, the hollow support structure and the long strip support 2 jointly support the range hood, as shown... Figure 3 As shown.

[0050] Preferably, this range hood assembly embodiment includes a foam top cover 7. The foam top cover 7 and the foam base 1 are spaced apart to form a receiving space suitable for accommodating and placing the range hood, such as... Figure 6 As shown. Further, this range hood assembly embodiment also includes a foam side panel (not shown in the figure). The foam side panel connects between the foam top cover 7 and the foam base 1. The foam top cover 7, foam base 1, and foam side panel together form a receiving space suitable for accommodating and placing the range hood. Further, this range hood assembly embodiment also includes a cardboard box (not shown in the figure). After placing the range hood into the receiving space formed by the foam top cover 7, foam base 1, and foam side panel, the assembled range hood, foam top cover 7, foam base 1, and foam side panel are placed together into the cardboard box, thus finally completing the assembly of this range hood assembly embodiment.

[0051] Exemplarily, this application proposes another embodiment of a range hood assembly, in which, in addition to the housing 8 and the smoke collection hood 9, a decorative cover 10 is also placed within the receiving space formed by the space between the foam top cover 7 and the foam base 1. Specifically, the housing 8 is placed inside the decorative cover 10, as shown below. Figure 7 As shown. This embodiment focuses on illustrating the differences from the above embodiments; for the same or similar parts of this embodiment, please refer to the above embodiments.

[0052] Exemplarily, this application proposes another embodiment of a smoke hood assembly, in which the housing 8 and the smoke hood 9 adopt a separate structure. A long strip-shaped support member 2 supports the top edge 13 of the rear wall of the housing 8 from bottom to top. Both the housing 8 and the smoke hood 9 are placed within an accommodating space. The separate housing 8 and smoke hood 9 allow for more flexible placement, helping to save space, reduce foam usage, and save costs. This embodiment focuses on illustrating the differences from the above embodiments; similar or identical parts of this embodiment can be referred to in the above embodiments.

[0053] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this application, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this application are intended to be illustrative and not limiting, unless explicitly stated otherwise. In practice, multiple features can be combined with each other where technically feasible and according to actual needs. Various substitutions, modifications, and alterations are also conceived without departing from the spirit and scope of this application.
