Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a range hood. Background Art

[0002] There are many types of existing range hoods, such as top-suction range hoods, side-suction range hoods, T-type range hoods, etc. The side-suction range hood usually includes a smoke collecting hood and a duct hood, the smoke collecting hood has a smoke collecting cavity, the smoke collecting cavity includes an upper cavity and a lower cavity that are connected to each other, the upper cavity is located above the lower cavity and extends forward relative to the lower cavity, the front side wall of the lower cavity is provided with a smoke inlet, the top wall of the upper cavity is provided with a connecting port, the smoke collecting hood is installed on the top wall of the upper cavity and is connected to the connecting port.

[0003] In order to facilitate cooking for users, a light board assembly for downward lighting is usually installed inside the upper cavity, and the bottom wall of the upper cavity has a light-transmitting portion located below the light board assembly. After the oil smoke flows into the lower cavity from the smoke inlet, it flows upward into the air duct cover. During this process, the oil smoke easily flows into the upper cavity and adheres to the surface of the lamp board assembly. The oil stains attached to the outer surface of the fan in the air duct cover are also easy to drip downward onto the lamp board assembly after accumulation. The oil stains attached to the lamp board assembly are not only easy to cause pollution and corrosion to the lamp board assembly, but may also penetrate into the interior of the lamp board assembly and directly affect the normal use of the lamp board assembly. For this reason, it is usually necessary to install a protective cover inside the upper cavity, and set the protective cover on the outer periphery of the lamp board assembly to reduce the risk of the lamp board assembly being contaminated and corroded by oil smoke. However, in this structure, the provision of the protective cover is likely to increase the production cost of the range hood. In addition, since the protective cover is located in the upper cavity, and the protective cover and the inner wall of the upper cavity need to be sealed well, the installation of the protective cover is relatively cumbersome and inconvenient. In addition, the provision of the protective cover is also likely to increase the thickness of the upper cavity, resulting in an increase in the height and volume of the entire range hood.

[0035] Reference Figures 1 to 6 In one embodiment of the utility model, a range hood is provided, comprising a smoke collecting hood 100 and an air duct cover 400. The smoke collecting hood 100 has a smoke collecting cavity 200. A smoke inlet 210 is provided on the front side wall of the smoke collecting cavity 200. A connecting port 220 communicating with the smoke collecting cavity 200 is provided on the top wall of the smoke collecting hood 100. The air duct cover 400 is mounted on the top wall of the smoke collecting hood 100 and communicated with the connecting port 220. The smoke collecting hood 100 has an extension portion 300 extending forward, the extension portion 300 is located in front of the connecting port 220 and has an installation cavity 301 independent of the smoke collecting cavity 200, a light board assembly 310 is installed in the installation cavity 301, and a bottom plate 320 of the installation cavity 301 has a light-transmitting portion located below the light board assembly 310.

[0036] By adopting the range hood of the embodiment of the utility model, the top wall of the smoke hood 100 is provided with a connecting port 220 connected to the smoke collecting cavity 200, the air duct cover 400 is installed on the top wall of the smoke hood 100 and is connected to the connecting port 220, and an extension portion 300 extending forward is provided on the smoke hood 100, the extension portion 300 is located at the front side of the connecting port 220 and is provided with a mounting cavity 301 which is independent of the connecting port 220, and the light board assembly 310 is directly installed in the mounting cavity 301 instead of being installed in the smoke hood 100, thereby not only reducing There is a risk that oil smoke enters the installation cavity 301 from the smoke collecting hood 100 and causes the lamp panel assembly 310 to be contaminated and corroded by the oil smoke. At the same time, the design of the smoke collecting cavity 200 including the upper cavity and the lower cavity in the prior art can also be eliminated, that is, there is no need to set up the upper cavity, which greatly reduces the height of the smoke collecting hood 100, thereby reducing the overall height of the range hood. In addition, the structure does not need to additionally install a protective cover for shielding the lamp panel assembly 310, thereby also reducing the height of the smoke collecting hood 100, making the structure simpler and reducing the production cost of the range hood.

[0037] It can be understood that the bottom plate 320 of the above-mentioned installation cavity 301 has a light-transmitting portion located below the light board assembly 310. Specifically, the bottom plate 320 of the installation cavity 301 can be provided with a light-transmitting hole for the light board assembly 310 to emit light downward. In addition, the bottom plate 320 of the installation cavity 301 can also directly adopt a glass panel. This structure not only makes it convenient for the light board assembly 310 to emit light downward, but also improves the aesthetics of the range hood.

[0038] Reference Figures 1 to 6 In some embodiments, the installation cavity 301 has a top plate 330, the top plate 330 and the top wall of the smoke hood 100 are an integrated structure, and the air duct cover 400 is at least partially installed on the top plate 330; two support members 340 are installed in the installation cavity 301, the upper end of the support member 340 abuts against the top plate 330, and the lower end of the support member 340 abuts against the bottom plate 320, and the lamp board assembly 310 is installed on the support member 340 and is spaced apart from the top plate 330.

[0039] By adopting the above structure, the top plate 330 of the installation cavity 301 and the top wall of the smoke hood 100 are an integrated structure, and the air duct cover 400 is at least partially installed on the top plate 330, thereby increasing the installation area between the air duct cover 400 and the smoke hood 100, and facilitating the stable installation of the air duct cover 400. By arranging two support members 340 in the installation cavity 301, the upper end of the support member 340 abuts against the top plate 330, and the lower end of the support member 340 abuts against the bottom plate 320, and the light board assembly 310 is installed on the support member 340 and arranged between the top plate 330, so that the support member 340 can support the top plate 330, and avoid the gravity of the air duct cover 400 acting on the top plate 330 and squeezing the light board assembly 310 in the installation cavity 301, thereby strengthening the structural strength of the extension part 300, and protecting the light board assembly 310, and avoiding damage to the light board assembly 310 due to squeezing.

[0040] It can be understood that during the oil fume extraction process, since the air duct cover 400 is at least partially installed on the top plate 330, when the oil on the surface of the fan assembly 410 in the air duct cover 400 accumulates and drips downward, it can directly drip on the upper surface of the top plate 330 and flow backward along the top plate 330 toward the connecting port 220, and finally flow into the smoke collecting chamber 200. Therefore, the top plate 330 can not only prevent the oil on the fan assembly 410 from dripping directly downward onto the lamp board assembly 310, but also play a drainage role for the oil, guiding the oil to flow into the smoke collecting chamber 200.

[0041] It is understandable that, referring to Figures 1 to 6In some embodiments, the top plate 330 is arranged to be tilted downward in the front-to-back direction, so that the oil droplets accumulated on the top plate 330 can flow smoothly along the top plate 330 to the inside of the smoke collecting chamber 200, thereby reducing the risk of difficulty in cleaning the range hood or generation of odor due to a large amount of oil droplets accumulated on the top plate 330 and unable to be discharged, which is beneficial to optimizing the kitchen environment and improving the user experience.

[0042] It is understandable that, referring to Figures 1 to 6 The top plate 330 of the installation cavity 301 and the top wall of the smoke hood 100 are an integrated structure. Specifically, the top plate 330 and the top wall of the smoke hood 100 are an integrated structure. The top plate 330 is located on one side of the communication port 220. The rear edge of the top plate 330 faces the communication port 220 and forms the front edge of the communication port 220. Of course, in addition to this, the top plate 330 can also be welded to the top wall of the smoke hood 100 to form an integrated structure, and the utility model does not make specific limitations on this.

[0043] It is understandable that the number of the above-mentioned support members 340 is two, which is only for Figures 1 to 6 As an exemplary illustration, the number of the support members 340 may be two, one, three, four or more, and the present invention does not specifically limit this.

[0044] Reference Figures 1 to 6 In some embodiments, one of the supports 340 is arranged in the left-right direction and is located at the rear side of the light board assembly 310 .

[0045] In the above structure, since the upper end of the support member 340 abuts against the top plate 330, and the lower end of the support member 340 abuts against the bottom plate 320, by arranging the support member 340 along the left-right direction on the rear side of the lamp board assembly 310, it can not only support the top plate 330, but also isolate the oil fume, thereby blocking the oil fume entering the installation cavity 301 from the smoke hood 100, and further reducing the risk of oil fume adhering to the lamp board assembly 310 and causing contamination and corrosion to the lamp board assembly 310.

[0046] It is understandable that one of the support members 340 is arranged along the left-right direction and located at the rear side of the light board assembly 310, which is only for Figures 1 to 6 As an exemplary illustration, when the number of the support members 340 is two or more, the number of the support members 340 arranged on the rear side of the light panel assembly 310 may be one, or may be two, three, four or more, and the present invention does not make any specific limitation on this.

[0047] It can be understood that in order to achieve a more comprehensive effect of shielding oil smoke, one of the support members 340 can be set on the rear side of the light board assembly 310 and extended in the left and right directions to abut the left and right ends of the installation cavity 301, or multiple support members 340 can be set on the rear side of the light board assembly 310 and multiple support members 340 can be arranged side by side in the left and right directions to abut the left and right ends of the installation cavity 301.

[0048] Reference Figures 1 to 6 In some embodiments, the front side wall of the installation cavity 301 is a baffle 350, which has a connecting portion 351 and a shielding portion 352. The connecting portion 351 is clamped between the top plate 330 and the bottom plate 320, and the shielding portion 352 is connected to the front end of the connecting portion 351. The upper edge of the shielding portion 352 extends upward and shields the top plate 330, and the lower edge of the shielding portion 352 extends downward and shields the bottom plate 320.

[0049] In the above structure, by providing the blocking bar 350, the connecting portion 351 of the blocking bar 350 is sandwiched between the top plate 330 and the bottom plate 320, thereby achieving stable installation of the blocking bar 350. By providing the shielding portion 352 at the front end of the connecting portion 351, the upper edge of the shielding portion 352 extends upward and shields the top plate 330, and the lower edge of the shielding portion 352 extends downward and shields the bottom plate 320, thereby making the front side edges of the top plate 330 and the bottom plate 320 both blocked by the shielding portion 352, so that there is no connection gap at the front end of the extension portion 300, thereby improving the aesthetics of the smoke hood 100.

[0050] It is understandable that the baffle 350 can be specifically made of aluminum bars. Since the aluminum bars are light and soft, they can reduce the weight of the smoke hood 100, making the range hood more lightweight. In addition, the aluminum bars can be oxidized into different colors as needed, thereby further improving the aesthetics of the range hood.

[0051] It can be understood that the above-mentioned baffle 350 has a connecting portion 351 and a shielding portion 352, wherein the connecting portion 351 and the shielding portion 352 can specifically be an integrally formed structure, thereby facilitating the production and processing of the baffle 350, while reducing the number of parts that need to be assembled, facilitating the assembly of the range hood, and improving the production efficiency of the range hood.

[0052] It can be understood that the above-mentioned connecting portion 351 is clamped between the top plate 330 and the bottom plate 320. In order to make the installation of the baffle 350 more firm and stable, the connecting portion 351 can be fixedly installed on the top plate 330 by means of a snap connection, a threaded connection, a welding connection, etc. Of course, in addition to this, the connecting portion 351 can also be fixedly installed on the bottom plate 320 by means of a snap connection, a threaded connection, a welding connection, etc., or the connecting portion 351 can be fixedly installed on the top plate 330 and the bottom plate 320 at the same time, and the present invention does not make any specific limitation on this.

[0053] Reference Figures 1 to 6 In some embodiments, a connecting frame 360 ​​is installed on the upper surface of the top plate 330 , and the connecting frame 360 ​​has a mounting portion 361 extending upward, and the air duct cover 400 is sleeved on the outer periphery of the connecting frame 360 ​​and connected to the mounting portion 361 .

[0054] By adopting the above structure, the connecting frame 360 ​​is installed on the upper surface of the top plate 330, and the air duct cover 400 is mounted on the outer periphery of the connecting frame 360 ​​and connected to the mounting portion 361 of the connecting frame 360. This not only facilitates the air duct cover 400 to be firmly installed on the top plate 330, but also allows the connecting frame 360 ​​to be shielded by the air duct cover 400, thereby making the appearance of the range hood more neat and beautiful.

[0055] It is understandable that, referring to Figures 1 to 6 In some embodiments, a fan assembly 410 is installed in the air duct cover 400, and the fan assembly 410 is fixedly connected to the connecting frame 360 ​​through a fan bracket 420. Therefore, the connecting frame 360 ​​can not only be used to install and fix the air duct cover 400, but also can be used to support and fix the fan assembly 410. Of course, in addition to this, the fan assembly 410 can also be fixedly connected to the inner wall of the air duct cover 400 through the fan bracket 420, and the utility model does not make specific limitations on this. Specifically, refer to Figures 1 to 6 In some embodiments, the number of fan brackets 420 connected to the fan assembly 410 is at least two, wherein at least one fan bracket 420 is connected to the connecting frame 360 ​​, and at least one fan bracket 420 is connected to the air duct cover 300 .

[0056] It is understandable that, referring to Figures 1 to 6 The connecting frame 360 ​​has a mounting portion 361 extending upward. Specifically, the connecting frame 360 ​​can be set as an L-shaped angle frame, which has a simple structure and is easy to produce.

[0057] It can be understood that the connecting frame 360 ​​is installed on the upper surface of the top plate 330. Specifically, the connecting frame 360 ​​can be fixedly installed on the upper surface of the top plate 330 by welding, or the connecting frame 360 ​​can also be fixedly installed on the upper surface of the top plate 330 by means of a snap connection or a threaded connection, etc. This utility model does not make any specific limitation on this.

[0058] Reference Figures 1 to 6 In some embodiments, the lower side of the air duct cover 400 has a first folded edge 401 bent inward, the inner side of the first folded edge 401 has a second folded edge 402 bent upward, the first folded edge 401 abuts against the upper surface of the top plate 330, and the second folded edge 402 is connected to the mounting portion 361.

[0059] By adopting the above structure, the first folded edge 401 and the second folded edge 402 are provided on the lower side of the air duct cover 400, so that the lower side of the air duct cover 400 is bent inward to form a U-shaped structure, thereby improving the structural strength of the air duct cover 400, and further improving the structural strength of the range hood. In addition, the air duct cover 400 can be abutted against the top plate 330 through the first folded edge 401, and connected to the mounting portion 361 of the connecting frame 360 ​​through the second folded edge 402, thereby increasing the contact area between the air duct cover 400 and the top plate 330, and making the installation of the air duct cover 400 more firm and stable.

[0060] Reference Figures 1 to 6 In some embodiments, the number of connecting frames 360 is three, one of which is arranged along the left-right direction and connected to the front side plate of the air duct cover 400, one of which extends along the front-to-back direction close to the connecting port 220 and connected to the left side plate of the air duct cover 400, and one of which extends along the front-to-back direction close to the connecting port 220 and connected to the right side plate of the air duct cover 400.

[0061] By adopting the above structure, the three connecting frames 360 are mutually surrounded to form a U-shape, thereby being able to connect and fix the front side plate, the left side plate and the rear side plate of the air duct cover 400, so that the installation of the air duct cover 400 is more firm and stable.

[0062] It is understandable that the number of the above-mentioned connecting frames 360 is three, which is only for Figures 1 to 6As an exemplary illustration, the number of the connecting frames 360 may be three, four, five, six or more, and the present invention does not make any specific limitation on this. It is only necessary that when the number of the connecting frames 360 is three or more, at least one connecting frame 360 ​​is arranged along the left-right direction and connected to the front side plate of the air duct cover 400, at least one connecting frame 360 ​​extends along the front-to-back direction close to the connecting port 220 and connected to the left side plate of the air duct cover 400, and at least one connecting frame 360 ​​extends along the front-to-back direction close to the connecting port 220 and connected to the right side plate of the air duct cover 400.

[0064] By adopting the above structure, the rear edge of the top plate 330 is bent downward to form an oil guide plate 331, and the oil guide plate 331 is connected to or abutted against the front inner wall of the smoke collecting chamber 200. As a result, when the oil smoke in the smoke collecting chamber 200 flows upward and adheres to the top plate 330, or when the oil stains on the surface of the fan assembly 410 directly drip downward to the top plate 330, the oil droplets on the top plate 330 can flow along the oil guide plate 331 to the inside of the smoke collecting chamber 200, that is, it can play a role in guiding the flow of oil droplets, thereby avoiding a large amount of oil stains accumulating on the top plate 330 and being difficult to clean.

[0065] It is understandable that when the oil guide plate 331 is connected to the front inner wall of the smoke collecting chamber 200, the oil guide plate 331 can be fixedly connected to the front inner wall of the smoke collecting chamber 200 by snap connection, threaded connection or other connection methods, which is not specifically limited in the present invention.

[0066] It can be understood that the oil guide plate 331 is connected to the front inner wall of the smoke collecting chamber 200. Figures 1 to 6 In some embodiments, the smoke hood 100 further includes a connecting plate 250, the front side wall of the smoke hood 100 is connected to the connecting plate 250, and the oil guide plate 331 is also connected to the connecting plate 250, that is, the front inner wall of the smoke hood 100 and the oil guide plate 331 are fixed together through the connecting plate 250, so that the structure of the smoke hood 100 is more stable and compact. Among them, the oil guide plate 331 and the connecting plate 250 can be fixedly connected by a snap connection, a threaded connection or other connection methods. Similarly, the connecting plate 250 and the front side wall of the smoke hood 100 can also be fixedly connected by a snap connection, a threaded connection or other connection methods, and the utility model does not make specific limitations on this.

[0067] Reference Figures 1 to 6In some embodiments, the upper edge of the smoke inlet 210 has a third folded edge 230 bent inwardly, and the third folded edge 230 and the front inner wall of the smoke collecting chamber 200 have an angle and form an oil guide groove 231 located above the smoke inlet 210. A fan assembly 410 is installed in the air duct cover 400. In the up and down direction, the projection of the rear end of the fan assembly 410 is located in the projection of the oil guide groove 231, or the projection of the rear end of the fan assembly 410 is located in front of the projection of the oil guide groove 231.

[0068] By adopting the above structure, when the oil on the surface of the fan assembly 410 accumulates into drops and drips downward, the oil droplets can directly drip into the oil guide groove 231, or drip on the front side of the oil guide groove 231 and flow downward in the front-to-back direction into the oil guide groove 231, and then flow along the oil guide groove 231 to the front inner wall of the smoke collecting chamber 200, and finally flow along the front inner wall of the smoke collecting chamber 200 to the bottom of the smoke collecting chamber 200. Specifically, the oil droplets accumulated on the surface of the fan assembly 410 can directly drip onto the top plate 330 or directly drip onto the front inner wall of the smoke collecting hood 100 located above the smoke inlet, and then flow downward into the oil guide groove 231 or the bottom of the smoke collecting chamber 200. In addition, the oil droplets accumulated on the surface of the fan assembly 410 can also directly drip into the oil guide groove 231, and then flow along the oil guide groove 231 to the front inner wall of the smoke collecting chamber 200, and finally flow downward to the bottom of the smoke collecting chamber 200. As a result, the structure can prevent the oil droplets accumulated on the surface of the fan assembly 410 from dripping downward directly onto the stove through the smoke inlet 210, thereby further reducing the risk of oil droplets contaminating the stove, making the kitchen environment cleaner and tidier, and helping to improve the user experience.

[0069] It is understandable that, referring to Figures 1 to 6 The other edges of the smoke inlet 210 are all provided with inwardly bent edges, which makes it easy to install an oil net for filtering oil smoke at the smoke inlet 210. In this structure, the setting of the third folded edge 230 can not only facilitate the formation of the oil guide groove 231, but also facilitate the installation of the oil net at the smoke inlet 210.

[0070] Reference Figures 1 to 6 In some embodiments, the front side wall of the smoke collecting chamber 200 has an oil guiding surface 240 arranged to be tilted backward along the up-down direction, the upper end of the oil guiding surface 240 is connected to or abuts against the oil guiding plate 331, the lower end of the oil guiding surface 240 is connected to the third folded edge 230, and the oil guiding groove 231 is located between the oil guiding surface 240 and the third folded edge 230.

[0071] By adopting the above structure, the oil droplets on the top plate 330 can flow downward along the oil guide plate 331 to the oil guide surface 240, and the oil droplets on the oil guide surface 240 can flow downward along the oil guide surface 240 to the oil guide groove 231. The setting of the oil guide surface 240 can further guide the oil droplets to flow downward, reducing the risk of a large amount of oil droplets accumulating on the inner wall of the smoke collecting chamber 200 and being unable to be discharged, resulting in difficulty in cleaning or generating odor, which is beneficial to optimizing the kitchen environment and enhancing the user experience.

[0072] It can be understood that the oil guiding surface 240 is arranged to be tilted backward along the up-down direction. Specifically, the oil guiding surface 240 can be an inclined surface arranged to be tilted backward along the up-down direction, or the oil guiding surface 240 can also be a curved surface arranged to be tilted backward along the up-down direction. The present invention does not make any specific limitation on this.

[0073] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
