[0060] Embodiment 1
[0061] See also Figures 1 to 10 , this embodiment provides a kitchen appliance, which may be a household appliance with a smoke extraction function, such as a range hood, an integrated stove, or an integrated range hood. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collection component, the smoke collection component includes a smoke collection hood, the smoke collection hood includes a first smoke collection hood 211 and a second smoke collection hood 212, and the second smoke collection hood 212 is movably connected to the first smoke collection hood 211. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collection structure, the smoke collection structure includes a smoke collection component and an air guide component, the smoke collection component includes a first smoke collection hood 211 and a second smoke collection hood 212, the air guide component includes an air guide plate 310, the second smoke collection hood 212 is movably connected to the first smoke collection hood 211, and the air guide plate 310 is movably connected to the first smoke collection hood 211. A fan is provided in the housing 100 or in the smoke collection hood, for sucking oil smoke and discharging it through a smoke guide channel in the housing 100.
[0062] In this embodiment, the first smoke hood 211 is fixedly arranged, and the second smoke hood 212 is movably connected to the first smoke hood 211 and can move between an open position and a closed position. In other embodiments, the first smoke hood 211 and the second smoke hood 212 are both movably arranged relative to the rear plate of the smoke hood, and the rear plate of the smoke hood can be fixed to a wall or a cabinet. The first smoke hood 211 and the second smoke hood 212 can move independently or in conjunction.
[0063] Specifically, a smoke collecting chamber is formed inside the first smoke collecting hood 211, and a mounting port 2111 connected to the smoke collecting chamber is provided in front of the first smoke collecting hood 211. The second smoke collecting hood 212 is movably arranged at the mounting port 2111, and the second smoke collecting hood 212 can move between an open position and a closed position. When the second smoke collecting hood 212 is in the open position, the second smoke collecting hood 212 protrudes from the front side of the first smoke collecting hood 211. The second smoke collecting hood 212 and the first smoke collecting hood 211 form a larger smoke collecting area, and the air inlet 2122 on the second smoke collecting hood 212 is closer to the stove, thereby improving the smoking effect. When the second smoke collecting hood 212 is in the closed position, the second smoke collecting hood 212 is located inside the first smoke collecting hood 211, and has a neat appearance and strong integrity.
[0064] The second smoke collecting hood 212 is provided with an air inlet 2122 connected to the smoke collecting chamber, and the air inlet 2122 may be provided on the front surface and / or the top surface of the second smoke collecting hood 212. In this embodiment, the front side of the second smoke collecting hood 212 is provided with an air inlet 2122 connected to the smoke collecting chamber. The oil smoke enters the smoke collecting chamber from the air inlet 2122, and after the oil smoke collides with the second smoke collecting hood 212, part of the oil smoke may condense on the second smoke collecting hood 212 and flow downward along the second smoke collecting hood 212.
[0065] A first oil guide structure 213 is provided in the smoke collecting chamber around the mounting opening 2111, and the first oil guide structure 213 guides the oil to flow from the upper side of the mounting opening 2111 to the left and right sides of the mounting opening 2111, so that the oil will not drip onto the second smoke collecting hood 212. The bottom end of the front surface of the second smoke collecting hood 212 is located in the mounting opening 2111 or at the rear side of the mounting opening 2111, so that the oil on the second smoke collecting hood 212 can flow into the smoke collecting chamber, and the oil on the second smoke collecting hood 212 is prevented from dripping onto the stove.
[0066] In this embodiment, when the second fume hood 212 is in the closed position, the front surface of the second fume hood 212 is flush with the surface where the mounting opening 2111 is located, that is, the bottom end of the front surface of the second fume hood 212 is located in the mounting opening 2111, and the oil flowing down the second fume hood 212 can flow into the first fume hood 211. When the second fume hood 212 is in the closed position, the bottom end of the front surface of the second fume hood 212 is located at the rear side of the mounting opening 2111, and the oil flowing down the second fume hood 212 can flow into the first fume hood 211.
[0067] Specifically, the first oil guide structure 213 includes a first oil guide plate 2131 and a second oil guide plate 2132. The first oil guide plate 2131 is disposed on the upper side of the mounting opening 2111 and has a first oil guide groove 2133 with an opening facing upward. The second oil guide plate 2132 is distributed on the left and right sides of the mounting opening 2111 and has a second oil guide groove 2134. Both ends of the first oil guide groove 2133 are connected to the second oil guide groove 2134. The oil accumulates in the first oil guide groove 2133 and flows along the first oil guide groove 2133 to the second oil guide groove 2134, and flows downward along the second oil guide groove 2134 to the bottom of the first fume hood 211. The cross-sectional shape of the first oil guide groove 2133 is V-shaped or U-shaped, and the cross-sectional shape of the second oil guide groove 2134 is V-shaped or U-shaped.
[0068] In some embodiments, the first oil guide groove 2133 extends parallel to the left and right directions of the first fume collecting hood 211, and some oil can be accumulated in the first oil guide groove 2133. In some embodiments, the first oil guide groove 2133 gradually tilts downward from the middle to the left and right ends, so that the oil flows to the two ends of the first oil guide groove 2133, which facilitates the oil to flow into the second oil guide groove 2134.
[0069] Since the second fume hood 212 is movably disposed at the mounting opening 2111 , there is a gap between the second fume hood 212 and the mounting opening 2111 , and the first oil guide structure 213 is disposed to prevent oil from flowing into the gap between the second fume hood 212 and the mounting opening 2111 , thereby preventing oil from dripping onto the second fume hood 212 .
[0070] Furthermore, the first oil guide structure 213 further includes a third oil guide plate 2135 disposed at the lower side of the installation opening 2111. The third oil guide plate 2135 is folded toward the inside of the smoke collecting chamber and extends downwardly from front to rear. The oil dripping from the second smoke collecting hood 212 into the installation opening 2111 flows along the third oil guide plate 2135 into the bottom of the first smoke collecting hood 211.
[0071] In this embodiment, the third oil guide plate 2135 is in contact with the inner wall of the front plate of the first fume collecting hood 211 to guide the oil to flow downward along the front plate of the first fume collecting hood 211 to the bottom of the first fume collecting hood 211 .
[0072] The top of the first smoke hood 211 is provided with an air outlet 2113 connected to the smoke collecting chamber. Oil guide side plates 214 are provided on both sides of the air outlet 2113 in the smoke collecting chamber. The second smoke hood 212 is located between the two oil guide side plates 214. The oil guide side plates 214 guide the oil to flow from top to bottom. After the oil smoke enters the smoke hood, it flows outward from the air outlet 2113. During the flow, the oil smoke contacts the oil guide side plates 214 and condenses on the oil guide side plates 214. The condensed oil droplets flow from top to bottom along the oil guide side plates 214. The second smoke hood 212 is located between the two oil guide side plates 214. Since the oil flows along the oil guide side plates 214, it will not drip onto the second smoke hood 212.
[0073] Specifically, the top of the oil guide side plate 214 is connected to the top plate of the first fume hood 211, the front end of the oil guide side plate 214 is connected to the front plate of the first fume hood 211, the rear end of the oil guide side plate 214 is connected to the rear plate of the first fume hood 211, and the bottom end of the oil guide side plate 214 is connected to the bottom plate of the first fume hood 211, so that a channel for the flow of oil smoke is formed between the two oil guide side plates 214, which is more convenient for the oil smoke to condense on the oil guide side plate 214. At the same time, an installation cavity is formed between the side of the oil guide side plate 214 away from the second fume hood 212 and the first fume hood 211, and a drive assembly for driving the air guide plate 310 can be installed in the installation cavity. By setting the oil guide side plate 214, the drive assembly is isolated from the oil smoke and kept clean.
[0074] The oil guide side plate 214 includes a first side plate 2141 and a second side plate 2142 arranged at an obtuse angle, wherein the first side plate 2141 is located at the upper part of the second smoke collecting hood 212, and the second side plate 2142 is located at the side of the second smoke collecting hood 212. The structural arrangement of the oil guide side plate 214 can fully utilize the internal space of the smoke collecting chamber.
[0075] The bottom end of the front surface of the second smoke collecting hood 212 is provided with an oil guide bottom plate 215, which is located in the smoke collecting cavity and extends downward from front to back. The oil flowing down from the second smoke collecting hood 212 can flow along the oil guide bottom plate 215 and drip to the bottom of the first smoke collecting hood 211.
[0076] The smoke collecting assembly further includes an oil cup 250, which is disposed at the bottom of the first smoke collecting hood 211. The first smoke collecting hood 211 is provided with an oil guide channel 2112 connected to the oil cup 250, so that the oil in the first smoke collecting hood 211 can flow into the oil cup 250. The oil guide channel 2112 can be a round hole, a long hole, etc., which is not limited here.
[0077] The smoke collecting assembly further includes a windshield 220. An air inlet 2122 communicating with the smoke collecting chamber is provided on the front side of the second smoke collecting hood 212. The windshield 220 is disposed at the air inlet 2122. An air inlet channel 201 is formed between the windshield 220 and the air inlet 2122. The air inlet channel 201 is the space between the windshield 220 and the air inlet 2122. There is a certain interval between the windshield 220 and the air inlet 2122, that is, the air inlet channel 201 is formed.
[0078] The air inlet channel 201 is connected to the air inlet 2122, and the windshield 220 compresses the negative pressure at the air inlet 2122 toward the air inlet channel 201, effectively distributing and diffusing the negative pressure area from the air inlet 2122 to the periphery of the windshield 220, thereby increasing the negative pressure around the entire smoke collecting chamber area. At the same time, the oil smoke can reduce its speed after colliding with the windshield 220, making it easier to be adsorbed by the negative pressure, thereby significantly improving the smoking effect. The windshield 220 also cools and condenses the oil smoke, causing the oil stains in the oil smoke to condense on the windshield 220, thereby increasing the oil stain adsorption and filtering effects.
[0079] The surface of the windshield 220 forms an oil guide surface, which guides the oil to flow from top to bottom to the second smoke collecting hood 212 or the first smoke collecting hood 211. The condensed oil flows downward along the windshield 220 until it flows into the oil cup 250. The windshield 220 plays an oil guide role, which can improve the cleanliness of the surface of the smoke collecting assembly. Specifically, the front surface and the rear surface of the windshield 220 can both play an oil guide role and can serve as oil guide surfaces.
[0080] In this embodiment, at least part of the front surface of the second smoke collecting hood 212 is recessed backward to form a receiving chamber 2121. The bottom wall of the receiving chamber 2121 is provided with an air inlet 2122. When the wind shield 220 is located in front of the air inlet 2122, the outer edge of the wind shield 220 and the inner wall of the receiving chamber 2121 form an air guide channel 202 connected to the air inlet channel 201. The gas enters the air inlet channel 201 from the air guide channel 202 and then enters the air inlet 2122. The air guide channel 202 guides the gas. The wind shield 220 compresses the negative pressure at the air inlet 2122 toward the air inlet channel 201, effectively distributing and diffusing the negative pressure area from the air inlet 2122 to the periphery of the wind shield 220, so that the negative pressure radiates to the air guide channel 202, thereby increasing the negative pressure around the entire smoke collecting area.
[0081] The cross-sectional area of the accommodating cavity 2121 gradually decreases from front to back, playing a role in guiding and compressing the air, increasing the wind speed and thus improving the smoking efficiency. The air inlet area of the air guiding channel 202 changes as the wind shield 220 moves relative to the air inlet 2122, and can adapt to different smoking conditions.
[0082] The bottom end of the wind shield 220 does not exceed the front side of the accommodating cavity 2121 to guide the oil to flow along the wind shield 220 to the bottom end of the wind shield 220, then flow along the side wall of the accommodating cavity 2121 to the bottom end of the second smoke hood 212 and then flow into the first smoke hood 211, and then flow into the oil cup 250.
[0083] In this embodiment, the wind shield 220 is movably connected to the first smoke collecting hood 211. The wind shield 220 can move relative to the air inlet 2122, and can be moved in at least one of the three directions of front-to-back direction, left-to-right direction, or up-to-down direction. For example, it can move in the front-to-back direction, or it can move in both the front-to-back direction and the left-to-right direction, or it can move in both the front-to-back direction and the up-to-down direction, or it can move in both the left-to-right direction and the up-to-down direction, which are not listed here one by one.
[0084] Since the wind shield 220 can move relative to the air inlet 2122, when there is a certain distance between the wind shield 220 and the air inlet 2122, the air inlet channel 201 is formed. During the movement of the wind shield 220 relative to the air inlet 2122, the air inlet area of the air inlet channel 201 changes to adapt to different smoking conditions. During the movement of the wind shield 220, the wind shield 220 and the second smoke collecting hood 212 move synchronously on at least part of the path; and / or, the wind shield 220 and the second smoke collecting hood 212 move relative to each other on at least part of the path.
[0085] The wind shield 220 can be switched between a use state and a non-use state. In the non-use state, the wind shield 220 closes the air inlet 2122 and the air inlet channel 201; in the use state, the air inlet channel 201 is opened and the size of the air inlet channel 201 is adjustable.
[0086] The smoke collecting assembly further includes a driving member 230 for driving the wind shield 220 to move. In this embodiment, during the movement of the wind shield 220, the upper end and the lower end of the wind shield 220 both move away from or close to the air inlet 2122, so that the air inlet port of the air inlet channel 201 is arranged in a ring shape around the periphery of the wind shield 220.
[0087] One end of the driving member 230 is movably connected to the first smoke hood 211, and the other end of the driving member 230 is movably connected to the windshield member 220. The lower end of the windshield member 220 is connected to the movable bracket 240, and the movable bracket 240 is movably connected to the first smoke hood 211. The driving member 230 itself is retractable. The driving member 230 can be an electric push rod, a cylinder, a hydraulic cylinder, etc. The windshield member 220 is fixedly connected to the movable bracket 240, and the windshield member 220 is driven to move by the extension of the driving member 230. The rotation axis of the windshield member 220 is the axis of the movable connection between the movable bracket 240 and the first smoke hood 211.
