Description

Technical Field

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

[0002] A range hood typically includes a fume hood and a wind cabinet. The fume hood has a fume collection chamber and a fume inlet connected to the fume collection chamber. The wind cabinet is mounted on top of the fume hood and has an air chamber connected to the fume collection chamber. A fan for extracting oil fumes is installed in the air chamber. When the range hood is operating, oil fumes flow from the smoke inlet through the fume collection chamber into the wind cabinet, and are finally discharged into the exhaust duct by the fan. During this process, oil stains are easily adsorbed onto the inner wall of the wind cabinet. Since the wind cabinet is typically mounted on the top wall of the fume hood, the oil stains adsorbed onto the inner wall of the wind cabinet tend to flow downward to the top wall of the fume hood and accumulate at the right angle formed by the lower periphery of the wind cabinet and the top wall of the fume hood, making the wind cabinet difficult to clean. In addition, some oil stains are easily adsorbed and accumulated on the inner wall of the fan's volute, which not only easily leads to a low fume extraction efficiency of the fan, but also makes it difficult to clean the fan, further increasing the difficulty of cleaning the wind cabinet.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] Reference Figures 1 to 7 One embodiment of the present invention provides a range hood, which includes a smoke collecting hood 100, a wind cabinet 200, a fan 300 and an oil guide structure. The smoke collecting hood 100 has a smoke collecting chamber 110, a front wall of the smoke collecting hood 100 is provided with a smoke inlet 120 connected to the smoke collecting chamber 110, and a top wall 140 of the smoke collecting hood 100 is provided with a mounting port 130 connected to the smoke collecting chamber 110. The wind cabinet 200 is installed on the top wall 140 of the smoke collecting hood 100 so that the lower periphery of the wind cabinet 200 is inserted into the mounting port 130, the wind cabinet 200 has an air cavity 210 connected to the smoke collecting chamber 110, a fan 300 is installed in the air cavity 210, and an oil dripping hole 320 is provided at the bottom of the volute 310 of the fan 300. The oil guide structure is installed in the smoke collecting chamber 110, the upper end of the oil guide structure is connected to or abuts the periphery of the installation port 130, and the lower end of the oil guide structure extends to or abuts the inner wall of the smoke collecting chamber 110; wherein, the oil guide structure is partially located below the oil drip hole 320.

[0036] In the range hood of the embodiment of the present invention, by directly inserting the lower periphery of the wind cabinet 200 into the installation opening 130 of the top wall 140 of the smoke collecting hood 100, the oil stains adsorbed on the inner wall of the wind cabinet 200 can flow downward along the inner wall of the wind cabinet 200 to the inside of the smoke collecting chamber 110, and are not easily accumulated at the connection between the wind cabinet 200 and the top wall 140, thereby greatly reducing the difficulty of cleaning the wind cabinet 200. In addition, by opening an oil dripping hole 320 at the bottom of the volute 310 of the fan 300 and arranging an oil guiding structure in the smoke collecting chamber 110, the oil adsorbed and accumulated in the volute 310 can drip onto the oil guiding structure through the oil dripping hole 320, and the oil guiding structure can guide the oil to flow downward to the inner wall of the smoke collecting hood 100 and flow along the inner wall of the smoke collecting hood 100 to the bottom of the smoke collecting chamber 110. This not only reduces the impact of the oil accumulation in the volute 310 on the operation of the fan 300, but also makes the cleaning of the fan 300 easier, thereby further reducing the difficulty of cleaning the wind cabinet 200.

[0037] Furthermore, when the range hood is in use, oil smoke flows from the smoke inlet 120 into the smoke collecting chamber 110 and then flows upward into the wind chamber 210. During this process, the oil smoke is not only easily adsorbed on the inner wall of the wind cabinet 200, but is also easily accumulated on the surface of the volute 310 of the fan 300. Therefore, by adopting the above-mentioned structure, at least part of the oil stains accumulated on the surface of the volute 310 of the fan 300 can drip downward to the oil guide structure, and thus the oil stains can be guided to the bottom of the smoke collecting chamber 110 through the oil guide structure. Thus, the range hood of the embodiment of the present invention can not only guide the oil stains adsorbed and accumulated on the inner wall of the wind cabinet 200 and the volute 310 into the smoke collecting chamber 110, but can also guide part of the oil stains adsorbed and accumulated on the surface of the volute 310 into the interior of the smoke collecting chamber 110.

[0038] It can be understood that in order to guide the oil stains on the oil guiding structure to the bottom of the smoke collecting chamber 110, in addition to extending the lower end of the oil guiding structure to be adjacent to or abutting the inner wall of the smoke collecting chamber 110, in some embodiments, the lower end of the oil guiding structure can also be extended toward the bottom of the smoke collecting chamber 110. At this time, the oil stains on the oil guiding structure can be directly guided to the bottom of the smoke collecting chamber 110, or, in some embodiments, a part of the lower end of the oil guiding structure can be extended toward the bottom of the smoke collecting chamber 110, and the other part can be extended to be adjacent to or abutting the inner wall of the smoke collecting chamber 110. As a result, a part of the oil stains on the oil guiding structure can flow directly to the bottom of the smoke collecting chamber 110 along the oil guiding structure, and the other part of the oil stains can flow along the oil guiding structure to the inner wall of the smoke collecting chamber 110, and then flow along the inner wall of the smoke collecting chamber 110 to the bottom of the smoke collecting chamber 110, thereby enabling the oil guiding structure to also guide the oil stains to the bottom of the smoke collecting chamber 110. The specific setting method of the oil guiding structure is not specifically limited in the present invention.

[0039] Reference Figures 1 to 7 In some embodiments, the periphery of the installation opening 130 has a first connecting portion 131 that bends downward toward the smoke collecting chamber 110 , and the lower periphery of the wind cabinet 200 abuts against and is connected to the first connecting portion 131 .

[0040] By adopting the above structure, a downwardly bent first connecting portion 131 is provided on the periphery of the installation opening 130. During installation, the lower periphery of the wind cabinet 200 can be inserted into the installation opening 130 and connected to the first connecting portion 131. This not only makes the installation of the wind cabinet 200 more convenient, but also makes the installation of the wind cabinet 200 more secure. In addition, since the lower periphery of the wind cabinet 200 is inserted into the installation opening 130, oil stains adsorbed on the inner wall of the wind cabinet 200 can flow downward along the inner wall of the wind cabinet 200 into the interior of the smoke collecting chamber 110, and are not easily accumulated at the connection between the wind cabinet 200 and the top wall 140, thereby greatly reducing the difficulty of cleaning the wind cabinet 200.

[0041] It can be understood that the lower periphery of the wind cabinet 200 is connected to the first connecting portion 131. Specifically, the lower periphery of the wind cabinet 200 and the first connecting portion 131 can be connected by fasteners such as screws or bolts, or the lower periphery of the wind cabinet 200 and the first connecting portion 131 can also be connected by a snap-fit structure or other connecting structure. The present invention does not make specific limitations on this.

[0042] Reference Figures 1 to 7 In some embodiments, the upper surface of the top wall 140 of the smoke hood 100 has a limiting groove 141 arranged around the outer periphery of the mounting opening 130, and the lower periphery of the wind cabinet 200 has an abutting portion 220 bent toward the air cavity 210, and the inner end of the abutting portion 220 is bent downward to form a second connecting portion 230, and the abutting portion 220 abuts against the bottom wall of the limiting groove 141, and the second connecting portion 230 is inserted into the mounting opening 130 and connected to the second connecting portion 230.

[0043] By adopting the above structure and providing the second connecting portion 230, the connection between the wind cabinet 200 and the smoke hood 100 can be made more convenient. By providing the limiting groove 141, during installation, the lower end of the wind cabinet 200 can be inserted into the installation opening 130 and the abutting portion 220 of the wind cabinet 200 abuts against the bottom wall of the limiting groove 141. As a result, the bottom wall of the limiting groove 141 can limit and support the wind cabinet 200, further making the connection between the first connecting portion 131 and the second connecting portion 230 simpler and more convenient. In addition, in the above structure, oil stains adsorbed on the inner wall of the wind cabinet 200 can flow downward along the inner wall of the wind cabinet 200, pass through the abutting portion 220 and the second connecting portion 230, and then flow into the interior of the smoke collection chamber 110. The oil stains are not easy to flow and accumulate at the connection between the wind cabinet 200 and the smoke hood 100, thereby reducing the difficulty of cleaning the wind cabinet 200.

[0044] It is understandable that the inner end of the abutting portion 220 is bent downward to form the second connecting portion 230 , wherein the inner end of the abutting portion 220 specifically refers to the end of the abutting portion 220 located in the air cavity 210 .

[0045] Reference Figures 1 to 7 In some embodiments, the oil guide structure includes a first oil guide plate 400 located below the oil drip hole 320, the upper end of the first oil guide plate 400 is connected to the periphery of the mounting port 130, and the lower end of the first oil guide plate 400 is connected to the front inner wall of the smoke collecting chamber 110.

[0046] In the above structure, by connecting the upper end of the first oil guide plate 400 to the periphery of the mounting port 130 and connecting the lower end of the first oil guide plate 400 to the front inner wall of the smoke hood 100, the oil adsorbed on the inner wall of the wind cabinet 200 can flow downward to the upper end of the first oil guide plate 400 and flow downward along the first oil guide plate 400 to the front inner wall of the smoke hood 100. In addition, since the first oil guide plate 400 is located below the oil drip hole 320, the oil accumulated in the volute 310 of the fan 300 can drip downward to the first oil guide plate 400 through the oil drip hole 320 and flow downward along the first oil guide plate 400 to the front inner wall of the smoke hood 100. It can be seen that by adopting the above structure, the oil accumulated on the inner wall of the wind cabinet 200 and the oil accumulated in the volute 310 of the fan 300 can flow to the front inner wall of the smoke collecting chamber 110 through the first guide plate, and then the oil can flow downward along the front inner wall of the smoke collecting chamber 110 to the bottom of the smoke collecting chamber 110, thereby better guiding the oil inside the wind cabinet 200 and reducing the difficulty of cleaning the wind cabinet 200.

[0047] Reference Figures 1 to 7In some embodiments, the first oil guide plate 400 includes a first oil guide surface 410 and a second oil guide surface 420. The first oil guide surface 410 is connected to the front edge of the smoke inlet 120 and is arranged to be tilted backward from top to bottom. The first oil guide surface 410 is located below the oil drip hole 320 and is spaced apart from the rear inner wall of the smoke collection chamber 110. The second oil guide surface 420 is connected to the lower end of the first oil guide surface 410 and is arranged to be tilted forward from top to bottom. The lower end of the second oil guide surface 420 is connected to the front inner wall of the smoke collection chamber 110.

[0048] By adopting the above structure, a first oil guiding surface 410 and a second oil guiding surface 420 are set on the first oil guide plate 400. The first oil guiding surface 410 is located below the oil dripping hole 320 and is connected to the front edge of the smoke inlet 120, so that the oil adsorbed on the inner wall of the wind cabinet 200 can flow downward to the first oil guiding surface 410, and the oil located in the volute 310 can drip to the first oil guiding surface 410 through the oil dripping hole 320, and some of the oil located on the outer surface of the volute 310 can also drip downward to the first oil guiding surface 410. By arranging the first oil guide surface 410 to be tilted backward from top to bottom, the first oil guide surface 410 can guide the oil to flow backward to the second oil guide surface 420, and guide the oil to the front inner wall of the smoke collecting chamber 110 through the second oil guide surface 420, and then the oil can flow downward along the front inner wall of the smoke collecting chamber 110 to the bottom of the smoke collecting chamber 110, thereby facilitating the guidance of the oil in the wind cabinet 200, making the cleaning of the wind cabinet 200 more convenient. In addition, by arranging the first oil guide surface 410 to be tilted backward from top to bottom and spaced apart from the rear inner wall of the smoke collecting chamber 110, and arranging the second oil guide surface 420 to be tilted forward from top to bottom, not only can the first oil guide surface 410 absorb the oil stains in the wind cabinet 200 to a large extent, but the second oil guide surface 420 can also guide the oil smoke flowing into the smoke collecting chamber 110 from the smoke inlet 120, so that the oil smoke at the smoke inlet 120 can flow upward along the second oil guide surface 420 into the wind chamber 210, thereby improving the oil smoke extraction efficiency of the range hood.

[0049] It is understood that the first oil guide surface 410 and the second oil guide surface 420 can be formed by bending the first oil guide plate 400, thereby simplifying and facilitating the production and processing of the first oil guide plate 400. Alternatively, in some embodiments, the first oil guide plate 400 can be formed by splicing two plates together, which is not specifically limited in this invention.

[0050] Reference Figures 1 to 7 In some embodiments, the lower end of the second oil guiding surface 420 is connected to the upper edge of the smoke inlet 120, and the smoke inlet 120 is installed with an oil net 121, the oil net 121 and the second oil guiding surface 420 are in contact with each other, or the oil net 121 is partially located below the second oil guiding surface 420.

[0051] By adopting the above structure, since the lower end of the second oil guiding surface 420 is connected to the upper edge of the smoke inlet 120, and the second oil guiding surface 420 is arranged to be tilted backward from top to bottom, the oil smoke at the smoke inlet 120 can directly flow upward along the second oil guiding surface 420 toward the wind cavity 210. In addition, the second oil guiding surface 420 can also guide the oil to flow to the oil net 121, so that the oil can flow downward along the oil net 121 to the bottom of the smoke collecting chamber 110.

[0052] Reference Figures 1 to 7 In some embodiments, the front edge of the first oil guiding surface 410 is bent upward to form a front bending portion 430, and the front bending portion 430 is connected to the front edge of the mounting opening 130; the left edge of the first oil guiding surface 410 is bent upward to form a left bending portion 440, and the left bending portion 440 is connected to the left edge of the mounting opening 130; the right edge of the first oil guiding surface 410 is bent upward to form a right bending portion 450, and the right bending portion 450 is connected to the right edge of the mounting opening 130.

[0053] By adopting the above structure, the arrangement of the front bending portion 430, the left bending portion 440 and the right bending portion 450 can not only better guide the oil stains on the inner wall of the wind cabinet 200 to the first oil guide plate 400, but also make the installation of the first oil guide plate 400 simpler and more convenient.

[0054] It can be understood that the front bending portion 430 is connected to the front edge of the mounting port 130, the left bending portion 440 is connected to the left edge of the mounting port 130, and the right bending portion 450 is connected to the right edge of the mounting port 130, wherein the front bending portion 430 and the front edge of the mounting port 130, the left bending portion 440 and the left edge of the mounting port 130, and the right bending portion 450 and the right edge of the mounting port 130 can be connected specifically by fasteners such as screws or bolts, or can also be connected by a snap-on structure or other connecting structure, and the present invention does not make specific limitations on this.

[0055] In some embodiments, the periphery of the mounting opening 130 includes a first connecting portion 131 that bends downward toward the smoke collection chamber 110. The lower periphery of the wind cabinet 200 abuts against and is connected to the first connecting portion 131. The front bend portion 430, the left bend portion 440, and the right bend portion 450 are all connected to the first connecting portion 131. This further simplifies and facilitates the installation of the first oil guide plate 400. Specifically, the front bend portion 430, the left bend portion 440, and the right bend portion 450 can be connected to a side surface of the first connecting portion 131 facing away from the mounting opening 130. Alternatively, the front bend portion 430, the left bend portion 440, and the right bend portion 450 can abut against the inner surface of the wind cabinet 200 and be connected to the first connecting portion 131 through the peripheral wall of the wind cabinet 200. The specific connection method of the front bend portion 430, the left bend portion 440, and the right bend portion 450 is not specifically limited in this utility model.

[0056] Reference Figures 1 to 7 In some embodiments, the oil guide structure includes two second oil guide plates 500 connected to the first oil guide plate 400, wherein the upper end of one second oil guide plate 500 is connected to the left edge of the mounting port 130, and the upper end of the other second oil guide plate 500 is connected to the right edge of the mounting port 130, and the lower ends of the two second oil guide plates 500 extend downward toward the bottom of the smoke hood 100.

[0057] By adopting the above structure, the oil stains adsorbed on the left inner wall and the right inner wall of the wind cabinet 200 can flow to the second oil guide plate 500 and flow downward along the second oil guide plate 500 to the bottom of the smoke collecting hood 100, thereby enabling the second oil guide plate 500 to cooperate with the first oil guide plate 400 to more comprehensively guide the oil stains on the inner wall of the wind cabinet 200 to the bottom of the smoke collecting chamber 110, reducing the accumulation of oil stains in the wind cabinet 200 and reducing the difficulty of cleaning the wind cabinet 200.

[0058] Reference Figures 1 to 7 In some embodiments, the rear end of the second oil guide plate 500 is connected to or abuts the rear inner wall of the smoke collecting hood 100, one of the two second oil guide plates 500 is connected to the left edge of the smoke inlet 120, and the other is connected to the right edge of the smoke inlet 120. The first oil guide plate 400 and the two second oil guide plates 500 divide the smoke collecting chamber 110 into a smoke inlet area 111 and two isolation areas 112. The smoke inlet area 111 connects the smoke inlet 120 and the air cavity 210, and the two isolation areas 112 are correspondingly located on the left and right sides of the smoke inlet area 111 and are isolated from each other.

[0059] By adopting the above structure, the first oil guide plate 400 and the second oil guide plate 500 can not only cooperate to guide the oil stains in the wind cabinet 200 downward to the bottom of the smoke collecting chamber 110, but also cooperate to guide the oil smoke at the smoke inlet 120 into the smoke inlet area 111 and guide the oil smoke upward into the wind chamber 210, which greatly improves the flow rate of the oil smoke and thus greatly improves the working efficiency of the range hood. In addition, the first oil guide plate 400 and the two second oil guide plates 500 divide the smoke collecting chamber 110 into a smoke inlet area 111 and two isolation areas 112. The two isolation areas 112 are located on the left and right sides of the smoke inlet area 111 respectively and are isolated from each other. This can prevent the oil smoke in the smoke inlet area 111 from flowing into the isolation areas 112, so that the isolation areas 112 can be used to install components such as wires and connecting rod mechanisms, and prevent the components in the isolation areas 112 from being contaminated by oil smoke. This not only reduces the difficulty of cleaning the range hood, but also reduces the risk of components such as wires and connecting rod mechanisms being damaged by oil smoke contamination, which is beneficial to extending the service life of the range hood.

[0060] Reference Figures 1 to 7 In some embodiments, the second oil guide plate 500 has a third oil guide surface 510, a fourth oil guide surface 520 and a fifth oil guide surface 530. The third oil guide surface 510 is connected to the edge of the mounting port 130 and extends downward. The fourth oil guide surface 520 is connected to the lower ends of the three oil guide surfaces and is inclined from top to bottom toward the left edge or the right edge of the smoke inlet 120. The fifth oil guide surface 530 is connected to the lower end of the third oil guide surface 510 and extends downward toward the bottom of the smoke collecting chamber 110. The front edge of the fifth oil guide surface 530 is connected to the left edge or the right edge of the smoke inlet 120.

[0061] By adopting the above structure, by setting the third oil guide surface 510, the fourth oil guide surface 520 and the fifth oil guide surface 530 on the second oil guide plate 500, not only can the smoke collecting chamber 110 be better separated, but the oil smoke at the smoke inlet 120 can be guided upward more smoothly into the wind chamber 210, and the oil stains on the inner wall of the wind cabinet 200 can be guided downward more smoothly to the bottom of the smoke collecting chamber 110.

[0062] It can be understood that the third oil guide surface 510, the fourth oil guide surface 520 and the fifth oil guide surface 530 can be specifically formed by bending the second oil guide plate 500, thereby making the production and processing of the second oil guide plate 500 more convenient. Alternatively, the third oil guide surface 510, the fourth oil guide surface 520 and the fifth oil guide surface 530 can also be formed by splicing two or three plates together, which is not specifically limited in the present invention.

[0063] In some embodiments, an oil cup 150 can be detachably installed at the bottom of the smoke hood 100. The oil cup 150 has an oil collecting trough that is interconnected with the smoke collecting chamber 110. Thus, the oil flowing to the bottom of the smoke collecting chamber 110 can drip into the oil collecting trough. Since the oil cup 150 can be detachably installed at the bottom of the smoke hood 100, the oil in the oil cup 150 can be conveniently handled, which is beneficial to improving the user experience.

[0064] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
