Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and more particularly to an oil fume extractor. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It can quickly remove waste from the stove and fumes produced during cooking and exhaust them outdoors, reducing pollution and purifying the air.

[0003] For example, Chinese utility model patent application number 202421564867.5 discloses a range hood, including: a shell with an internal fume extraction channel and a guide plate, the guide plate including a main flow section extending upwards in a rear-to-front direction, the main flow section having a smoke inlet communicating with the fume extraction channel; and a diversion structure disposed in the fume extraction channel for dividing the fume extraction channel into a left channel and a right channel, the diversion structure including a rotating part rotatably disposed in the fume extraction channel, the rotating part being used to adjust the size of the left channel and the right channel, at least a portion of the rotating part being located above the smoke inlet, and a clearance structure being provided between the front edge of the rotating part and the portion of the main flow section located above the smoke inlet.

[0004] The aforementioned patent pertains to a side-suction range hood, which has the problem of smoke rising upwards when there is a large amount of cooking fumes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a range hood that solves the problem of oil fumes escaping upwards in side-suction range hoods.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a range hood, including a smoke collection hood, the smoke collection hood including a side suction part, and a main smoke inlet provided on the front side of the side suction part, characterized in that: the smoke collection hood also includes a top suction part, the top suction part is provided with a smoke collection cavity, the smoke collection cavity is formed by the bottom of the top suction part being recessed upwards, the range hood also includes a smoke baffle, the smoke baffle having a first state and a second state, when the smoke baffle is in the first state, it is located on the front side of the side suction part and closes the main smoke inlet; when the smoke baffle is in the second state, it is located in the smoke collection cavity and makes the top suction part form a ring suction, and at this time the main smoke inlet is open.

[0007] By incorporating a top-mounted suction unit and a baffle plate that can move relative to the smoke collection hood and switch positions, the top-mounted suction unit can create a ring-like suction effect when the baffle plate is inside the smoke collection chamber. At the same time, the smoke inlet on the side suction unit becomes the main smoke inlet. This allows for the rapid and large-volume intake of cooking fumes using the main smoke inlet of the side suction unit, as well as the absorption of cooking fumes escaping upwards from the side suction unit. Furthermore, the baffle plate allows for switching between different smoke extraction modes, making it convenient to handle different cooking scenarios.

[0008] To create a circumferential suction effect in the top suction section, the top suction section includes a first smoke inlet on the front side of the smoke collection chamber, a second smoke inlet on the rear side of the smoke collection chamber, a third smoke inlet on the left side of the smoke collection chamber, and a fourth smoke inlet on the right side of the smoke collection chamber. The first smoke inlet is located on the front side of the smoke baffle, the second smoke inlet is located on the rear side of the smoke baffle, the third smoke inlet is located on the left side of the smoke baffle, and the second smoke inlet is located on the right side of the smoke baffle.

[0009] Preferably, the smoke baffle is rotatably connected to the smoke collection hood via a rotating shaft that extends along the left and right direction of the range hood, thereby allowing the smoke baffle to easily switch between two states.

[0010] Furthermore, the side suction portion extends longitudinally, while the top suction portion extends laterally forward from the top of the side suction portion.

[0011] Furthermore, the front side of the side suction unit gradually tilts backward from top to bottom to conform to the rising path of the oil fumes, making it easier to inhale the oil fumes.

[0012] Furthermore, the angle between the smoke baffle and the external mounting base when the smoke baffle is in the first state is α, and the angle between the smoke baffle in the first state and the second state is β, and β≥α+90° is satisfied.

[0013] Therefore, when the smoke baffle is in the second state, it is tilted downwards from front to back, and the oil on the smoke baffle can flow backwards into the smoke collection hood and be collected, thus preventing the oil from dripping directly downwards.

[0014] The height of the front end of the top suction unit is X3, and the height of the smoke collection hood is X4, satisfying the following conditions: X3≥10mm, X4≤10X3. This ensures sufficient smoke collection space in the smoke collection chamber of the top suction unit and facilitates the installation of control panels, while the side suction unit has a certain height to ensure effective smoke extraction and avoids the smoke collection hood from being too high and compressing the cooking space.

[0015] Compared with the prior art, the advantages of this utility model are as follows: by setting a top suction part and a baffle plate that can switch positions relative to the smoke collection hood, when the baffle plate is in the smoke collection chamber, the top suction part can form a ring suction effect, while the smoke inlet on the side suction part becomes the main smoke inlet. This allows for the rapid and large-scale intake of oil fumes using the main smoke inlet of the side suction part, as well as the absorption of oil fumes escaping upwards from the side suction part. In addition, the baffle plate can be used to switch the smoke extraction mode to conveniently cope with different cooking scenarios. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0022] See Figures 1-4 A range hood includes a smoke collection hood 1, which includes a side suction part 11 and a top suction part 12, forming a "7" shape. The side suction part 11 extends longitudinally, while the top suction part 12 extends laterally forward from the top of the side suction part 11. Preferably, the front side of the side suction part 11 can gradually tilt backward from top to bottom.

[0023] The side suction part 11 is provided with a main smoke inlet 111 on the front side, and the top suction part 12 is provided with a smoke collection chamber 121, which is formed by the bottom of the top suction part 12 being recessed upward.

[0024] The range hood also includes a baffle plate 2 that can move relative to the smoke collection hood 1. The baffle plate 2 has a first state and a second state. When it is in the first state, it is located in front of the side suction part 11 and closes the main smoke inlet 111. When it is in the second state, it is located inside the smoke collection chamber 121 and makes the top suction part 12 perform a ring suction. "Ring suction" means that the fumes are sucked in from the gap between the periphery of the baffle plate 2 and the wall of the smoke collection chamber 121 formed by the top suction part 12.

[0025] The top suction unit 12 includes a first smoke inlet 122 on the front side of the smoke collection chamber 121, a second smoke inlet 123 on the rear side of the smoke collection chamber 121, a third smoke inlet 124 on the left side of the smoke collection chamber 121, and a fourth smoke inlet 125 on the right side of the smoke collection chamber 121. The first smoke inlet 122 is located on the front side of the smoke baffle 2, the second smoke inlet 123 is located on the rear side of the smoke baffle 2, the third smoke inlet 124 is located on the left side of the smoke baffle 2, and the second smoke inlet 125 is located on the right side of the smoke baffle 2. These smoke inlets together constitute auxiliary smoke inlets.

[0026] In this embodiment, the smoke baffle 2 is rotatably connected to the smoke collection hood 1 via a rotating shaft 21, thereby allowing switching between a first state and a second state. Its driving mechanism can be a commonly used type such as a motor or an electric actuator. The rotating shaft 21 can be positioned at the junction between the top suction section 12 and the side suction section 11.

[0027] See Figure 4 When the smoke baffle 2 is in the first state, the angle between it and the external mounting base (usually a vertical wall) is α, where 0° < α < 90°. The angle between the smoke baffle 2 in the first state and the second state is β, that is, the rotation angle of the smoke baffle 2 from the first state to the second state is β. If β ≤ α + 90°, when the smoke baffle 2 is in the second state, the smoke baffle 2 gradually tilts upward from front to back, and the oil on the smoke baffle 2 flows downward from the front end of the smoke baffle 2. If β ≥ α + 90°, when the smoke baffle 2 is in the second state, the smoke baffle 2 gradually tilts downward from front to back, and the oil on the smoke baffle 2 flows downward from the rear end of the smoke baffle 2. Preferably, this method avoids the oil dripping from the front, and when the oil flows downward from the rear end, it can enter the interior of the smoke collection hood 1.

[0028] The height of the front end of the top suction unit 12 is X3, and the overall height of the fume hood 1 is X4, satisfying the following relationship: X3≥10mm, X4≤10X3. This ensures sufficient smoke collection space in the smoke collection chamber 121 inside the top suction unit 12, and facilitates the installation of control panels, etc., while the side suction unit 11 has a certain height to ensure the smoke extraction effect, and avoids the fume hood 1 being too high and compressing the cooking space.

[0029] See Figures 1-2When the user simply steams or boils food, the amount of oil smoke is relatively small, so the micro-steaming mode can be turned on. In the micro-steaming mode, the baffle plate 2 is in the first state of closing the main smoke inlet 111, and the oil smoke channel rises to the smoke collection chamber 121 and enters the inside of the smoke collection hood 1 from the front, back, left and right directions of the smoke collection chamber 121.

[0030] See Figure 3 When the user starts cooking, the amount of oil fumes is relatively large. The smoke baffle 2 opens to the lower surface of the smoke collection chamber 121. The main oil fume channel is close to the side suction part 11 and enters the inside of the smoke collection hood 1 through the main smoke inlet 111. At the same time, the oil fumes that are not sucked up by the main smoke inlet 111 rise to the smoke collection chamber 121 and the excess oil fumes are sucked up by the smoke collection chamber 121.
