Description

Technical Field

[0001] The utility model relates to an oil fume purification device, in particular to an installation structure of a power device and a range hood applying the installation structure. Background Art

[0002] As an essential kitchen appliance in every family, the range hood sucks oil fume from the air inlet through an impeller rotating at high speed in the volute, filters the oil fume by the impeller, and discharges the filtered oil fume from the air outlet to complete the purification of kitchen air. A reasonable air inlet setting is beneficial to improving the oil fume suction effect, reducing the escape of oil fume, and improving the kitchen air quality.

[0003] In order to reduce noise and improve the user experience, currently, kitchen appliances, especially range hoods, have gradually emerged with the fan placed in the ceiling, with the human ear far from the sound source, and are equipped with sound-absorbing and noise-reducing air ducts to make the kitchen quieter and allow people to immerse themselves in the joy of cooking. Currently, the fans on the ceiling are mainly connected to the top of the room with screw rods, and the screw rods are composed of metal expansion screws and screw rods, as disclosed in the Chinese patent with the application number 202221537478.4.

[0004] This structure is a suspension structure. In the part connecting the power device (fan), there is only positioning in the vertical height direction, and it is not fixed in the horizontal direction. After the power device is placed, there will be a shaking phenomenon, especially when the vibration is obvious, the shaking is even more obvious. Moreover, the fan platform is connected by four screw rods, and two installation workers are required to cooperate to complete the installation, which requires more personnel. In addition, the screw connection itself has no shock-absorbing design, and there is a risk of the expansion screw loosening and falling off during long-term vibration.

[0005] Therefore, further improvement is still needed. Summary of the Utility Model

[0006] The first technical problem to be solved by the utility model is to provide an installation structure of a power device aiming at the deficiencies of the above-mentioned existing technology, which improves the installation convenience and ensures the stability after installation.

[0007] The second technical problem to be solved by the utility model is to provide a range hood applying the above installation structure.

[0008] The technical solution adopted by the utility model to solve the above first technical problem is: an installation structure of a power device, including a power device and an installation structure for installing the power device, the installation structure including a hanging bracket and a hanging ear fixed to the power device; characterized in that:

[0009] The hanger includes a first hanger body extending horizontally, a second hanger body extending vertically, and a strengthening bracket connected between the first hanger body and the second hanger body, thus forming a triangular hanger as a whole. The second hanger body is used to be fixed to an external vertical wall.

[0010] The hanger further includes a lug formed at the lower end of the first hanger body. The lug extends horizontally towards the power device, and the hanging ear is fixed to the lug.

[0011] By using a triangular hanger, the triangular structure is stable and there will be no obvious shaking. It is firm after installation and can be adaptively installed in the vertical direction, enabling the power device to effectively adapt to other components and making the overall performance of the machine reach the best. The first hanger body is used for guiding, and the horizontal lug is used for pre-support, so that only one installer is required to complete the installation, saving manpower.

[0012] Furthermore, there are two lugs which are formed at the opposite ends of the first hanger body. A notch is formed between the two lugs, and the hanging ear can be inserted from the end of the hanger or the notch, which can meet the installation in a small space.

[0013] Furthermore, for the convenience of fixing the hanger and the power device, the installation structure further includes a screw. The screw passes through the lug and the hanging ear from bottom to top, thereby fixing the hanger and the hanging ear, and further fixing the hanger to the power device.

[0014] Furthermore, the installation structure further includes a shock pad. The shock pad is arranged between the lug and the hanging ear and between the lug and the screw. Thus, the shock pad can be effectively used for shock absorption, avoiding the transmission of the vibration of the whole machine under large resistance to the hanger, thereby ensuring the stability of the hanger installation.

[0015] Furthermore, the installation structure further includes a support plate and a lead screw. The hanging ear is supported on the support plate. The lead screw extends into the interior of the support plate from bottom to top, and the lead screw is threadedly connected to the support plate. Thus, the rotation of the lead screw can drive the support plate to move up and down, and the height of the hanging ear can be adjusted by the lead screw, and then the installation height of the power device can be adjusted.

[0016] Furthermore, to ensure smooth rotation of the lead screw, a thrust bearing is installed at the upper end of the lead screw located inside the support plate.

[0017] Furthermore, to ensure that at least part of the lead screw is located inside the support plate, a cover plate is sleeved on the outer periphery of the lead screw. The cover plate is lower than the upper end of the lead screw, and the cover plate is located at the bottom of the support plate.

[0018] Further, for further shock absorption, a rubber ring is provided under the support plate. The mounting structure further includes screws and shock pads. The screws pass through the lug, rubber ring, support plate, shock pad, and hanging ear from bottom to top, thereby fixing the hanging bracket and the hanging ear.

[0019] Further, to limit the positions of the support plate and the hanging ear and ensure the installation efficiency, the mounting structure further includes a limit support member. The limit support member includes a horizontal limit support portion located on the lug and a vertical limit support portion extending upward from the end of the horizontal limit support portion close to the second hanging bracket body. The support plate is arranged on the horizontal limit support portion of the limit support member, and the vertical limit support portion abuts against the corresponding ends of the support plate and the hanging ear.

[0020] The first technical solution adopted by the present invention to solve the above-mentioned second technical problem is: an oil fume suction machine, characterized in that: the power device mounting structure as described above is applied, and there are two sets of the hanging brackets and the hanging ears, which are respectively arranged on opposite sides of the power device.

[0021] The second technical solution adopted by the present invention to solve the above-mentioned second technical problem is: an oil fume suction machine, characterized in that: the power device mounting structure as described above is applied, mounting holes are provided on the lugs, the mounting structure further includes screws, the screws pass through the lugs and the hanging ears from bottom to top, thereby fixing the hanging brackets and the hanging ears. The mounting holes are oblong or long waist-shaped holes, and the length direction of the mounting holes is the direction in which the first hanging bracket body extends horizontally, thereby facilitating the adjustment of the position of the power device in the horizontal direction, making it better match the installation of other parts of the oil fume suction machine and achieving the best overall performance.

[0022] Compared with the prior art, the advantages of the present invention are as follows: by using a triangular hanging bracket, the triangular structure is stable, there will be no obvious shaking, and it is stable after installation. It can be adaptively installed in the vertical direction, enabling the power device to effectively match other components and achieving the best overall performance; the first hanging bracket body is used for guiding, and the horizontal lug is used for pre-support, so that only one installer is required to complete the installation, saving manpower; through the setting of the hanging bracket and the support plate, it is convenient to adjust the height and horizontal position of the power device, thereby effectively matching other components and making the overall performance of the machine reach the best.

[0033] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions.

[0034] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed by the present utility model can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0035] See Figures 1 to 3, A range hood, comprising an air inlet assembly 3, a power device 1, and a connecting pipe 4 connected between the air inlet assembly 3 and the power device 1. The power device 1 includes a box body 11 and a fan system (not shown) disposed within the box body 11. The power device 1 is for installation above a ceiling. The air inlet assembly 3, the connecting pipe 4, etc. of the range hood are prior arts, as can be seen from the Chinese patents disclosed in the applicant's application numbers 202322035585.8, 202222680884.2, etc.

[0036] The above-mentioned air inlet assembly 3, power device 1, and connecting pipe 4, as well as other components not shown, constitute the range hood body. The range hood further includes an installation structure for hanging the range hood body onto an external installation base, such as a vertical wall 100. The installation structure includes a hanging bracket 21. In this embodiment, to avoid using the traditional screw connection scheme, metal expansion screws are used to fix the hanging bracket 21, and the hanging bracket 21 is directly fixed to the concrete wall 100 of the room.

[0037] There are two symmetrical hanging brackets 21, which are respectively disposed on opposite sides of the power device 1. In this embodiment, they are on the left and right sides. The hanging bracket 21 is integrally triangular in shape, including a first hanging bracket body 211 extending horizontally, a second hanging bracket body 212 extending longitudinally, and a strengthening bracket 213 connected between the first hanging bracket body 211 and the second hanging bracket body 212. Among them, the first hanging bracket body 211 extends horizontally back and forth (this direction is the length direction of the first hanging bracket body 211), the second hanging bracket body 212 extends upward from the rear end of the first hanging bracket body 211, and the strengthening bracket 213 is disposed between the front end of the first hanging bracket body 211 and the upper end of the second hanging bracket body 212. The above-mentioned hanging bracket 21 is preferably an integrally formed structure. The two first hanging bracket bodies 211 are respectively located on the left and right sides of the box body 11 of the power device 1, the second hanging bracket body 212 is located above the rear side of the box body 11 of the power device 1, and they can be fixed to each other by screws. The strengthening bracket 213 is located above the left and right sides of the box body 11 of the power device 1.

[0038] By adopting the above-mentioned triangular hanging bracket 21, since the hanging bracket 21 is fixed to the vertical wall 100, the installation height can be adjusted according to the installation height requirement of the power device 1, and the stability of the hanging bracket 21 can be ensured, without any swaying in the horizontal or vertical direction, ensuring that there is no swaying due to collision during installation. When connecting the hanging bracket 21 and the power device 1, a rubber pad 24 (to be described in detail below) is provided in the middle to prevent direct contact between the box body 11 and the hanging bracket 21, avoiding the slight vibration transmitted to the hanging bracket 21 part when the fan system installed in the box body 11 rotates at a high speed under a large resistance, thereby ensuring the reliability of the installation of the hanging bracket 21.

[0039] See Figures 4 to 10, the first hanger body 211 has a certain height as a plate member with a certain longitudinally extending height (this direction is the height direction of the first hanger body 211). The hanger 21 further includes lugs 214 formed at the lower end of the first hanger body 211. There are two lugs 214 formed at the opposite ends (front and rear ends) of the first hanger body 211. The lugs 214 on the two hangers 21 extend laterally towards each other.

[0040] After the power device 1 is placed on the lugs 214 of the hanger 21, the hanger 21 can provide a pre - support for the power device 1. The power device 1 can slide in the horizontal direction, and at this time, the first hanger body 211 can play a guiding role. Thus, an installer can complete the installation, and the installer only needs to exert force when lifting the power device 1. This installation method is simple, convenient, and labor - saving.

[0041] A notch 215 is formed between the two lugs 214. This is to facilitate the installation of the power device 1. The power device 1 is placed on the hanger 21 for pre - support, reducing the installation space, so that the power device 1 can be fixed smoothly even in a relatively small space.

[0042] The lugs 214 are provided with mounting holes 216. The mounting holes 216 can be in the shape of a long strip or an oblong, and the length direction is the front - rear direction, that is, the direction in which the first hanger body 211 extends laterally. The mounting structure further includes a hanging ear 22 and a screw 23. The hanging ear 22 is fixed to the box body 11 of the power device 1. The hanging ear 22 can be in an inverted L - shape. The horizontal part is used to be fixed to the hanger 21, and the vertical part is used to be fixed to the box body 11. The screw 23 passes through the mounting hole 216 on the lug 214 and the hanging ear 22 from bottom to top. The screw 23 is threadedly connected to the hanging ear 22, thereby directly or indirectly fixing the hanger 21 and the hanging ear 22, and further fixing the hanger 21 to the box body 11. The mounting structure further includes a shock - absorbing pad 24, which is arranged between the lug 214 and the hanging ear 22 and between the lug 214 and the screw 23, such as it can be arranged between the upper surface of the lug 214 and the hanging ear 22, the lower surface of the lug 214, and around the hole of the lug 214 through which the screw 23 passes. The shock - absorbing pad 24 can be a rubber pad, which plays a role in shock isolation and prevents the vibration of the power device 1 from being transmitted to the hanger 21.

[0043] Since the mounting hole 216 is in the shape of an oblong, the front - rear position of the screw 23 relative to the lug 214 can be adjusted to ensure the best installation and matching position between the power device 1 and the air - inlet assembly 3.

[0044] At least one lug 214 on the first hanger body 211, which is the lug 214 near the second hanger body 212 in this embodiment, at least partially depresses downward to form a depression 2141, and the above-mentioned mounting hole 216 is located in the depression 2141. The mounting structure further includes a support plate 25, a limit support 26, a rubber ring 27 and a lead screw 28. The vertical cross-section of the limit support 26 is L-shaped, that is, it has a horizontal limit support portion 261 located in the depression 2141 of the lug 214 and a vertical limit support portion 262 extending upward from the depression 2141. The vertical limit portion 262 is located at the rear end of the horizontal limit support portion 261. Thus, when installing the power device 1, it can play a limiting role, playing two roles of limiting the horizontal height and the front-back distance from the wall. The hanging ear 22 is supported on the support plate 25. The support plate 25 is arranged at intervals above the horizontal limit support portion 261 of the limit support 26. A threaded hole 263 for installing the lead screw 28 is provided on the horizontal limit support portion 261 of the limit support 26. The lead screw 28 passes upward through the threaded hole 261 of the limit support 26 and extends into the interior of the support plate 25. The lead screw 28 is threadedly connected to the support plate 25. A thrust bearing 281 is installed at the upper end of the lead screw 28 inside the support plate 25 to ensure smooth rotation of the lead screw 28. A cover plate 282 is sleeved on the outer periphery of the lead screw 28. The cover plate 282 is lower than the upper end of the lead screw 28. The cover plate 282 is located at the bottom of the support plate 25. Thus, it can be ensured that part of the lead screw 28 is always inside the support plate 25. A slot (not shown, such as a slotted hole, a cross slot, etc.) that can be twisted by a tool is provided at the lower end of the lead screw 28. When twisting the lead screw 28 with a tool, the support plate 25 can move up and down in the height direction under the drive of the lead screw 28. Thus, the height of the hanging ear 22 is adjusted, and then the height of the power device 1 is adjusted. The vertical limit support portion 262 can be in contact with the rear end of the support plate 25 and the rear end of the hanging ear 22, limiting the front-back distance from the wall 100, which can ensure a successful installation at one time and greatly improve the installation efficiency.

[0045] The support plate 25 is provided with an opening 251 for the screw 23 to pass through. The screw 23 passes through the lug 214, the rubber ring 27, the support plate 25, the shock pad 24 and the hanging ear 22 from bottom to top. The screw 23 is threadedly connected to the hanging ear 22. Two shock-absorbing structures, namely the shock pad 24 and the rubber ring 27, are installed between the screw 23 and the hanging ear 22, greatly improving the shock-absorbing effect.
