A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0050] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0051] See also Figures 1 to 7 The present invention provides a kitchen appliance, which may be a range hood, an integrated stove, an integrated range hood, or other household appliances with a smoking function. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collecting assembly, the smoke collecting assembly includes a first smoke collecting hood 211, a second smoke collecting hood 212, and a smoke blocking member 220, and the second smoke collecting hood 212 is movably connected to the first smoke collecting hood 211.

[0052] The first smoke collecting hood 211 has a smoke collecting chamber with a front opening, and the second smoke collecting hood 212 is movably arranged at the opening of the smoke collecting chamber. A smoke inlet connected to the smoke collecting chamber is opened on the front side of the second smoke collecting hood 212, 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, it protrudes from the front side of the first smoke collecting hood 211; the smoke barrier 220 is arranged at the smoke inlet, and an air inlet channel 200 is formed between the smoke barrier 220 and the smoke inlet, and when the second smoke collecting hood 212 is in the open position, at least part of the smoke barrier 220 is located behind the smoke inlet.

[0053] When opened, the second smoke hood 212 protrudes from the front side of the first smoke hood 211, so that the second smoke hood 212 and the first smoke hood 211 form a larger smoke collection area, and the smoke inlet on the second smoke hood 212 is closer to the stove, thereby improving the smoking effect. When closed, the second smoke hood 212 is located inside the first smoke hood 211, with a neat appearance and strong integrity.

[0054] The gas enters the smoke collecting chamber from the air inlet channel 200, and the smoke shield 220 compresses the negative pressure at the smoke inlet toward the air inlet channel 200, effectively distributing and diffusing the negative pressure area from the smoke inlet to the periphery of the smoke shield 220, thereby increasing the negative pressure around the entire smoke collecting chamber area. At the same time, the oil smoke first passes through the smoke shield 220 before entering the smoke collecting chamber, which can reduce the speed of the oil smoke and effectively prevent the oil smoke from escaping from both sides, significantly improving the smoking effect. The smoke shield 220 also cools and condenses the oil smoke, causing the oil stains in the oil smoke to condense on the smoke shield 220, thereby increasing the oil stain adsorption and filtration effect.

[0055] Among them, the air inlet channel 200 is the space between the smoke barrier 220 and the smoke inlet. There is a certain interval between the smoke barrier 220 and the smoke inlet, so that the oil smoke can enter the smoke inlet, that is, the air inlet channel 200 connected to the smoke inlet is formed. The gas enters the smoke collecting chamber from the air inlet channel 200, and the air inlet port of the air inlet channel 200 is the port through which the wind flows from the air inlet channel 200 to the smoke collecting chamber. It can be only on the upper side of the smoke barrier 220, or it can be above and on the left and right sides of the smoke barrier 220, or it can be arranged in a ring around the circumference of the smoke barrier 220, with a larger air inlet area.

[0056] The air inlet ports of the air inlet channel 200 can be evenly distributed or unevenly distributed around the circumference of the smoke barrier 220. In the present embodiment, the air inlet area of ​​the air inlet channel 200 gradually decreases from top to bottom. The upper air inlet area is large, and the lower air inlet area is small, so that a negative pressure area is formed below the smoke barrier 220, which improves the smoking efficiency. The smoke enters the smoke inlet from the bottom of the air inlet channel 200, and part of the smoke enters the smoke inlet from the top or left and right sides of the air inlet channel 200. In other embodiments, the air inlet area of ​​the air inlet channel 200 gradually increases from top to bottom; or, the air inlet area of ​​the air inlet channel 200 gradually decreases or increases from left to right.

[0057] In this embodiment, when the second smoke collecting hood 212 is in the open position, the smoke shield 220 is completely located behind the smoke inlet. When opened, the smoke shield 220 is far away from the stove, which prolongs the path for the gas to reach the smoke shield 220. After passing through the smoke inlet, the gas collides with the smoke shield 220. The smoke shield 220 compresses the negative pressure at the smoke inlet toward the air inlet channel 200, effectively distributing and diffusing the negative pressure area from the smoke inlet to the periphery of the smoke shield 220, and increasing the negative pressure around the entire smoke collecting chamber area. At the same time, the collision of oil smoke and the smoke shield 220 can reduce the oil smoke speed, making it easier to be adsorbed by the negative pressure, effectively preventing the oil smoke from escaping from both sides, and significantly improving the smoking effect.

[0058] In other embodiments, the upper portion of the smoke barrier 220 is located in front of the smoke inlet, and the lower portion of the smoke barrier 220 is located behind the smoke inlet. In other embodiments, the upper portion of the smoke barrier 220 is located behind the smoke inlet, and the lower portion of the smoke barrier 220 is located in front of the smoke inlet.

[0059] When the smoke shield 220 is entirely located behind the smoke inlet, the air inlet port of the air inlet channel 200 is arranged in a ring shape around the circumference of the smoke shield 220; or, the air inlet port of the air inlet channel 200 is located above and on the left and right sides of the smoke shield 220.

[0060] The smoke shield 220 can be an integrally formed structure or a split structure. The edge of the smoke shield 220 can be bent backwards, which not only plays a role in guiding wind, but also facilitates processing and production.

[0061] In some embodiments, the smoke shield 220 is a windshield. In some embodiments, the smoke shield 220 is an oil screen. In some embodiments, the smoke shield 220 is not a plate-like structure, but a columnar, block-like or windshield curtain.

[0062] The smoke barrier 220 may be a flat plate or a bent plate. With the plane where the smoke inlet is located as the reference plane, when the smoke barrier 220 is a flat plate, the smoke barrier 220 may be parallel to the reference plane, or may be arranged at an acute angle to the reference plane so that the air inlet area of ​​the air inlet channel 200 gradually decreases from top to bottom. When the smoke barrier 220 is a bent plate, the smoke barrier 220 may be L-shaped, Z-shaped, S-shaped or other shapes, as long as part of the smoke barrier 220 is located behind the smoke inlet.

[0063] In this embodiment, the smoke shield 220 includes a first plate 221 and a second plate 222 connected to each other, and the angle between the first plate 221 and the second plate 222 is between 110° and 130°. Specifically, the second plate 222 is disposed at the bottom end of the first plate 221, and the angle between the first plate 221 and the second plate 222 is 120°.

[0064] The smoke shield 220 is fixedly or movably connected to the second smoke collecting hood 212 , or the smoke shield 220 is fixedly or movably connected to the first smoke collecting hood 211 .

[0065] In this embodiment, the smoke shield 220 is connected to the second smoke hood 212. In order to make full use of the space, part of the front surface of the second smoke hood 212 is recessed inward to form a receiving cavity, and the smoke inlet is opened on the bottom wall of the receiving cavity. The smoke shield 220 does not protrude from the front surface of the second smoke hood 212 to ensure the appearance of integrity.

[0066] The smoke shield 220 is fixedly connected to the second smoke hood 212 and is detachable, which is convenient for installation, disassembly and replacement. In this embodiment, one end of the smoke shield 220 is rotatably connected to the second smoke hood 212, and the other end of the smoke shield 220 is clamped, threaded or magnetically connected to the second smoke hood 212.

[0067] Specifically, a mounting bracket 240 is provided on the second smoke hood 212, a plug port 241 is provided on the mounting bracket 240, and a plug pin 225 is provided at the bottom end of the smoke shield 220, and the plug pin 225 is plugged into the plug port 241 and can rotate in the plug port 241. The mounting bracket 240 and the second smoke hood 212 can be detachably connected or integrally formed. In other embodiments, the bottom end of the smoke shield 220 can be rotatably connected to the second smoke hood 212 via a rotating shaft.

[0068] The first smoke collecting hood 211 or the second smoke collecting hood 212 is provided with a magnetic base 250, a magnetic member is provided on the magnetic base 250, and the top of the smoke barrier 220 is magnetically connected to the magnetic member. The magnetic base 250 can be provided in front of the smoke barrier 220, magnetically attracting the front surface of the smoke barrier 220; the magnetic base 250 can also be provided behind the smoke barrier 220, magnetically attracting the rear surface of the smoke barrier 220. In order to facilitate the adjustment of the angle of the smoke barrier 220, the magnetic base 250 can be provided as a retractable base.

[0069] In some embodiments, the smoke shield 220 is connected to the second smoke hood 212 by a buckle. Specifically, a slot is provided on the second smoke hood 212, and a buckle is provided on the smoke shield 220, and the buckle is connected to the slot. During installation, the smoke shield 220 is pressed onto the second smoke hood 212, so that the buckle is connected to the slot.

[0070] At least two smoke inlets are provided at the front side of the second smoke collecting hood 212, and a set of smoke shields 220 is provided corresponding to each smoke inlet. In this embodiment, two smoke inlets are provided, corresponding to the left and right burners of the stove. A set of smoke shields 220 is provided corresponding to each smoke inlet. For each smoke inlet, one smoke shield 220 may be provided, or two smoke shields 220 may be provided. When the smoke shield 220 is movable, the entire smoke shield 220 may be movable, or a part of the smoke shield 220 may be movable.

[0071] In some embodiments, the first smoke hood 211 includes a smoke hood rear plate, and the smoke shield 220 is fixedly connected or movably connected to the smoke hood rear plate. Specifically, the smoke hood rear plate is the rear plate of the first smoke hood 211.

[0072] It can be that when the second smoke collecting hood 212 is closed, the upper part of the smoke barrier 220 is located in front of the smoke inlet, and the lower part of the smoke barrier 220 is located behind the smoke inlet; when the second smoke collecting hood 212 is opened, the entire smoke barrier 220 is located behind the smoke inlet. It can also be that when the second smoke collecting hood 212 is closed, the upper part of the smoke barrier 220 is located in front of the smoke inlet, and the lower part of the smoke barrier 220 is located behind the smoke inlet; when the second smoke collecting hood 212 is opened, the upper part of the smoke barrier 220 is located in front of the smoke inlet, and the lower part of the smoke barrier 220 is located behind the smoke inlet. It can also be that when the second smoke collecting hood 212 is closed, the entire smoke barrier 220 is located behind the smoke inlet; when the second smoke collecting hood 212 is opened, the entire smoke barrier 220 is located behind the smoke inlet.

[0073] During the opening of the second smoke collecting hood 212 , the smoke shield 220 and the second smoke collecting hood 212 move synchronously on at least a portion of the path, and / or the smoke shield 220 and the second smoke collecting hood 212 move relative to each other on at least a portion of the path.

[0074] In some embodiments, the smoke collecting assembly includes a smoke shield 220 and an oil net, which is used to filter the oil smoke flowing through the smoke inlet. The oil net is arranged on the air inlet channel 200; or, the oil net is arranged in front of the smoke shield 220; or, the oil net is arranged behind the smoke shield 220. The setting position of the oil net is not limited, as long as it can filter the oil smoke. Since the external oil smoke can only enter the smoke collecting chamber through the air inlet channel 200, the oil net is arranged on the air inlet channel 200 to filter the oil smoke entering the air inlet channel 200.

[0075] The smoke shield 220 can be a windshield, and the oil net can be provided with one layer, or two layers or more. In the case of providing the oil net, the oil net can be connected to the smoke shield 220, or the oil net can be connected to the first smoke hood 211 or the second smoke hood 212.

[0076] When the smoke shield 220 is connected to the oil net, the smoke shield 220 and the oil net can be fixed as one, which can be a snap connection, a threaded connection or a magnetic connection. When the smoke shield 220 is connected to the oil net, the smoke shield 220 can be disassembled separately or as a whole with the oil net.

[0077] When the oil net is connected to the first smoke hood 211, the first smoke hood 211 and the oil net may be fixedly connected or movably connected. The fixed connection may be a snap connection, a threaded connection or a magnetic connection, and the movably connected may be a sliding connection or a rotating connection. In some embodiments, the first smoke hood 211 includes a smoke hood rear plate, and the smoke shield 220 is fixedly connected or movably connected to the smoke hood rear plate. Specifically, the smoke hood rear plate is the rear plate of the first smoke hood 211.

[0078] When the oil net is connected to the second fume hood 212, the first fume hood 212 and the oil net may be fixedly connected or movably connected. The fixed connection may be a snap connection, a threaded connection or a magnetic connection, and the movable connection may be a sliding connection or a rotating connection.

[0079] In some embodiments, the angle of the smoke barrier 220 is adjustable in the left-right direction around the first smoke hood 211; and / or the position of the smoke barrier 220 is adjustable along the front-back direction of the first smoke hood 211. By adjusting the smoke barrier 220, the air inlet area of ​​the air inlet channel 200 can be changed. When the smoke barrier 220 is connected to the second smoke hood 212, the adjustment structure for adjusting the position is arranged between the smoke barrier 220 and the second smoke hood 212; when the smoke barrier 220 is connected to the oil net, the adjustment structure for adjusting the position is arranged between the smoke barrier 220 and the oil net. The adjustment structure can adopt existing structures, such as a cylinder, a push rod motor, etc., to change the angle and position of the smoke barrier 220.

[0080] In some embodiments, the adjustment structure includes a screw rod, which passes through the smoke barrier 220 and is connected to the threaded hole on the second smoke collecting hood 212 or the oil net. By rotating the screw rod, the length of the screw rod outside the threaded hole can be changed, thereby changing the position of the smoke barrier 220. Generally, the longer the length of the screw rod outside the threaded hole, the farther the smoke barrier 220 is from the first smoke inlet, and the larger the air inlet area of ​​the air inlet channel 200.

[0081] It is understandable that a mounting hole is provided on the smoke barrier 220, and a screw rod is passed through the mounting hole. In order to limit the smoke barrier 220, a limiting sleeve can be sleeved on the screw rod, and the limiting sleeve and the head of the screw rod clamp the smoke barrier 220. The limiting sleeve can be an elastic ring sleeved on the screw rod.

[0082] In order to further adjust the position of the smoke barrier 220, two limiting sleeves can be provided on each screw rod, and the two limiting sleeves are distributed on the front and rear sides of the smoke barrier 220 to clamp the smoke barrier 220. Not only can the position of the smoke barrier 220 be changed by rotating the screw rod, but also the position of the smoke barrier 220 can be changed by sliding the two limiting sleeves on the screw rod, which has a larger adjustment range.

[0083] In some embodiments, the smoke shield 220 is rotatably connected to the second smoke hood 212 or the oil net through a rotating shaft, and the smoke shield 220 and the second smoke hood 212 or the oil net can be locked by a locking member. When the angle of the smoke shield 220 needs to be adjusted, the locking member is loosened, the smoke shield 220 is rotated to the desired position, and then the locking member is locked.

[0084] The locking member can be a bolt and a nut. The smoke shield 220 is provided with a first mounting hole for passing the bolt, and the second smoke collecting hood 212 or the oil net is provided with a second mounting hole for passing the bolt. Both the first mounting hole and the second mounting hole are long holes, which facilitate alignment after adjusting the angle of the smoke shield 220. The bolt is locked with the nut after passing through the first mounting hole and the second mounting hole.

[0085] In some embodiments, the smoke barrier 220 is connected to the first smoke collecting hood 211. The smoke barrier 220 and the first smoke collecting hood 211 can be fixedly connected or movably connected. When the smoke barrier 220 is fixedly connected to the first smoke collecting hood 211, in the closed state, the bottom of the smoke barrier 220 is located in front of the smoke inlet, and the top of the smoke barrier 220 is located behind the smoke inlet. As the second smoke collecting hood 212 is opened, the smoke barrier 220 is completely located behind the smoke inlet and the air inlet area of ​​the air inlet channel 200 is gradually reduced from top to bottom. When the smoke barrier 220 is movably connected to the first smoke collecting hood 211, as the second smoke collecting hood 212 is opened, the smoke barrier 220 can move forward and backward to form an air inlet channel 200 between the smoke barrier 220 and the smoke inlet.

[0086] The smoke collecting assembly further includes an oil cup 230, which is disposed at the bottom of the first smoke collecting hood 211. The bottom end of the second smoke collecting hood 212 is located inside the first smoke collecting hood 211 and above the oil cup 230, so that oil can flow into the oil cup 230.

[0087] The surface of the smoke shield 220 forms an oil guide surface 223, and the oil guide surface 223 guides the oil to flow into the oil cup 230. The smoke shield 220 also cools and condenses the oil smoke, so that the oil stains in the oil smoke condense on the smoke shield 220, and the condensed oil stains flow downward along the smoke shield 220 into the oil cup 230. The smoke shield 220 plays an oil guide role, which can improve the cleanliness of the surface of the smoke collecting component. Figure 6 The dashed arrow in the middle shows the flow direction of the oil along the smoke shield 220 .

[0088] Specifically, both the front surface and the rear surface of the smoke barrier 220 can guide the oil and can serve as the oil guide surface 223. In this embodiment, since the front surface of the smoke barrier 220 directly contacts the oil smoke and cools and condenses the oil smoke, there is more oil on the front surface of the smoke barrier 220. By setting the front surface of the smoke barrier 220 to be concave toward the back of the smoke barrier 220 as the main oil guide surface 223, in the open state, the lower part of the oil guide surface 223 is tilted downward, so that the oil can flow into the oil cup 230.

[0089] Since the mounting bracket 240 is disposed at the bottom of the smoke barrier 220 , the oil flowing downward along the smoke barrier 220 flows onto the mounting bracket 240 and then flows downward along the mounting bracket 240 , and the mounting bracket 240 plays an oil guiding role.

[0090] In some embodiments, see Figure 8 The smoke barrier 220 is a windshield, and a fence hole 224 is provided on the windshield. The fence hole 224 increases the air intake of the windshield, thereby improving the smoking effect. The fence hole 224 can be provided at any position of the windshield as required. For example, the fence hole 224 is provided at the bottom of the smoke barrier 220, thereby increasing the air intake at the bottom of the smoke barrier 220. The fence hole 224 can be circular, oval or long strip. In the present embodiment, the fence hole 224 is long strip. The fence hole 224 can extend in the left-right direction of the smoke barrier 220, or can extend in the up-down direction of the smoke barrier 220.

[0091] On the premise that a smoke inlet is provided at the front side of the second smoke collecting hood 212, a second smoke inlet communicating with the smoke collecting chamber may be provided on the top surface of the second smoke collecting hood 212. When the second smoke collecting hood 212 is closed, it is located inside the first smoke collecting hood 211, and the second smoke inlet is located inside the first smoke collecting hood 211, so that the second smoke inlet can be protected to prevent dust accumulation. When the second smoke collecting hood 212 is opened, it protrudes from the front side of the first smoke collecting hood 211 and the second smoke inlet is located outside the first smoke collecting hood 211.

[0092] In some embodiments, a third smoke inlet is provided on the left side and / or right side of the second smoke collecting hood 212, and the third smoke inlet connects the outside with the smoke collecting chamber. The smoke inlet, the second smoke inlet and the third smoke inlet exist at the same time, forming a uniform negative pressure zone inside the smoke collecting assembly to the maximum extent, and adding a smoke inlet on the left side and / or right side of the second smoke collecting hood 212 can increase the negative pressure on the left and right sides, thereby improving the smoke leakage on the left and right sides.

[0093] The moving path of the second smoke hood 212 can be a straight line or a curve; in the present embodiment, the second smoke hood 212 rotates around a fixed axis, and the second smoke hood 212 flips forward while approaching the stove below. Specifically, the bottom end of the second smoke hood 212 is rotatably connected to the first smoke hood 211. A pin or a rotating shaft is provided at the rotating connection. In other embodiments, the second smoke hood 212 can move along a first straight line, and the first straight line extends downwardly from the back to the front, so that the second smoke hood 212 moves downward while protruding from the front side of the first smoke hood 211, approaching the stove below.

[0094] 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, a second smoke collection hood 212 and a smoke barrier 220, and the second smoke collection hood 212 is movably connected to the first smoke collection hood 211.

[0095] The air guide assembly includes an air guide plate 310, which is movably connected to the first smoke collecting hood 211. The first smoke collecting hood 211 supports the second smoke collecting hood 212 and the air guide plate 310, and the first smoke collecting hood 211 is connected to the housing 100. A fan is provided in the housing 100 to absorb oil smoke and discharge it through the smoke guide channel in the housing 100.

[0096] In the closed state, the second smoke hood 212 is located inside the first smoke hood 211, and at least part of the air guide plate 310 covers the second smoke hood 212, with a neat appearance and strong integrity; when switching from the closed state to the open state, the air guide plate 310 flips forward, the second smoke hood 212 flips forward and protrudes from the front side of the first smoke hood 211, and the air guide plate 310, the second smoke hood 212 and the first smoke hood 211 form a smoke collecting cavity. Since the second smoke hood 212 protrudes from the front side of the first smoke hood 211, the second smoke hood 212 is closer to the stove, improving the smoking effect; there is no need to reduce the distance between the smoke collecting cavity and the stove countertop, and the smoking effect is guaranteed without affecting the user's cooking operation and cooking utensils by the smoke collecting structure.

[0097] In the present embodiment, one air guide plate 310 is provided. At least part of the air guide plate 310 covers the second smoke collecting hood 212, and the air guide plate 310 may be completely covered by the second smoke collecting hood 212, or part of the air guide plate 310 may be covered by the second smoke collecting hood 212. In other embodiments, two or more air guide plates 310 may be provided. When two or more air guide plates 310 are provided, at least one air guide plate 310 may cover the second smoke collecting hood 212, and the other air guide plates 310 may not cover the second smoke collecting hood 212. The air guide plate 310 covers the second smoke collecting hood 212, and may completely cover the second smoke collecting hood 212, or may cover part of the second smoke collecting hood 212.

[0098] When in use, the position of the kitchen appliance is set as needed so that the smoke collecting chamber formed in the open state is just above the stove, so as to form a negative pressure area above the stove, which can effectively absorb the oil smoke into the smoke collecting chamber, thereby improving the smoke extraction effect of the range hood. Usually, the bottom of the smoke collecting chamber is the air inlet, which faces downward to face the stove, and the smoke flows into the smoke collecting chamber from bottom to top.

[0099] The air guide plate 310 and the second smoke collecting hood 212 can both move relative to the first smoke collecting hood 211. The two can move independently of each other, share a driving mechanism, or be linked to each other. The driving mechanism can be a conventional mechanism for driving the air guide plate 310 and the second smoke collecting hood 212 to flip.

[0100] In some embodiments, the kitchen appliance further includes a first detection component 410 and a second detection component 420. The first detection component 410 is disposed at the bottom of the housing 100. When the air guide plate 310 is in a closed state, the air guide plate 310 is in a closed position that does not block the first detection component 410. The first detection component 410 can obtain whether the stove in the detection area is ignited; the second detection component 420 is disposed on the front surface of the second smoke hood 212. When the air guide plate 310 is in an open state, the air guide plate 310 flips forward, and the second smoke hood 212 protrudes from the front side of the first smoke hood 211. The second detection component 420 can obtain whether the stove in the detection area is turned off.

[0101] In the closed state, the first detection component 410 can detect whether the stove is ignited; in the open state, the second detection component 420 can detect whether the stove is turned off; the first detection component 410 and the second detection component 420 cooperate to obtain the state of the stove in the detection area regardless of whether it is in the closed state or the open state, without being affected by the flipping angle of the air guide plate 310, taking into account both intelligent detection and a larger smoke collection chamber.
