These and / or other aspects and advantages of the present invention will become apparent and easy to understand from the description of the embodiments in conjunction with the accompanying drawings below, wherein: FIG. 1 is an oil fume according to an embodiment of the present invention 2 is a schematic diagram of a cyclone generated by the range hood shown in FIG. 1; FIG. 3 is a schematic diagram of a range hood according to another embodiment of the present invention; FIG. 4 is shown in FIG. 3 FIG. 5 is a schematic structural diagram of a range hood according to another embodiment of the present invention; FIG. 6 is a schematic diagram of a cyclone generated by the range hood shown in FIG. 5.

The embodiments of the present invention are described in detail below, and the illustrations of the embodiments are presented in the accompanying drawings, wherein the same or similar symbols throughout the specification refer to the same or similar elements or elements having the same or similar functions . The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention, and should not be construed as limiting the present invention.

Range hoods generally generate a certain negative pressure at the exhaust port through the rotating impeller, which attracts nearby air inflows. However, in fact, this attraction decreases rapidly as it moves away from the smoking port. At the standard installation height of the range hood, the range hood The suction of the cooker reaches the surface of the cooktop is very weak. In the numerical simulation research, the inventor of the case found that the range of the low-pressure area generated by the range hood is very small through the pressure distribution chart, and the area near the cooktop has almost no relationship with the surrounding environment. The pressure difference causes the oil fume to not get enough power to move toward the exhaust port, and the direction of the suction power generated by the range hood is divergent. The range hood sucks a lot of air from other directions, not just the oil fume from below. Although the range hood has a relatively stable exhaust air volume, due to the mixing of clean air, the amount of fume emissions is not large.

Specifically, during the cooking process, the oil fume diffuses in all directions, the farther it is from the source of the oil fume, the larger the cross-sectional area of the oil fume movement, and the more difficult it is to converge into a small cross-section airflow to pass through the exhaust port of the range hood. The hood's gathering power to the fumes becomes weaker and weaker, resulting in the hood not being able to effectively gather the fumes, which results in a high fumes exudation rate. If the fumes cannot be pumped away in time, the fumes will diffuse around due to the influence of gravity. Sucked away by a range hood.

In the design of the range hood in the related art, in order to improve the removal rate of the range hood, the power of the range hood is increased by increasing the number of exhaust vanes to increase the exhaust volume of the range hood. However, this method cannot increase the suction range of the range hood, and increases the exhaust air volume while increasing the exhaust air volume of clean air. The true exhaust air volume volume cannot be increased correspondingly. Moreover, the disadvantage of this method is that the energy consumption of the product is very large, and the noise is greater.

To this end, the present invention provides an oil fume rotation device for a range hood. The oil fume rotation device of the range hood has a simple structure, reliable connection of various components, convenient assembly and disassembly, and can form a strong and powerful cyclone, thereby expanding the range hood. The suction range of the body reduces the power requirement of the range hood and reduces energy consumption, thereby reducing the working noise of the range hood and improving the quality of the range hood.

The following specifically describes the fume turning device S2 for a range hood according to an embodiment of the present invention with reference to the accompanying drawings of FIGS. 1 to 6.

The oil fume spinner S2 of the range hood according to the present invention includes a wind deflector 100, which has an air duct (not shown), and the air deflector 100 is provided with an air inlet (not shown) communicating with the air duct. (Illustrated) and the air outlet 10c, the air deflector 100 uses the airflow emitted from the air outlet 10c to form a tornado-like cyclone for collecting oil fume.

In other words, the oil fume spin concentrator S2 is mainly composed of the air deflector 100. When the oil fume spin concentrator S2 is in use, the air fume deflector 100 of the oil fume spin concentrator S2 can be fixed on the hood body S1 of the range hood S. It can also be fixed on the cooktop T, and can also be fixed on the rear wall corresponding to the range hood S to form a back plate.

The air deflector 100 defines an air duct. The air deflector 100 is provided with an air inlet and an air outlet 10c. The air inlet and the air outlet 10c are respectively communicated with the air duct. When the range hood S is in operation, the air guide The air around the wind plate 100 enters the air duct of the wind deflector 100 through the air inlet to form an airflow, and then is discharged through the air outlet 10c. The exhausted airflow drives the air and oil fume around the fume swirling device S2 and the stove T. And generate a strong shear force on it, so as to form a tornado-like cyclone, to prevent oil fume from spreading around.

Specifically, when the range hood S is working, the range hood body S1 sucks oil fume, so that there is a pressure difference between the cooktop T and the range hood body S1 in the up-down direction, that is, when the range hood body S1 is working, it is in the up-down direction. The area near and above the hood body S1 is a low pressure area, and the area near the cooktop T is a high pressure area, so that the pressure difference is transmitted to form a bottom-up thrust. At the same time, the air from the air deflector 100 of the oil fume spinner S2 exits. The converged airflow discharged from the gas port 10c merges the air and oil fume between the cooktop T and the hood body S1, and generates a strong shear force on the confluence area, that is, it meets the conditions of tornado-like cyclone formation, thereby driving The surrounding air and oil fume form a tornado-like cyclone that spirals upward, that is, the airflow discharged from the air outlet 10c of the wind deflector 100 has a strong force to push the surrounding matter into the cyclone and perform a spiral upward movement. Because of the tornado-like cyclone It has a hollow tube shape, with a rapid upward airflow inside, like a natural material rapid transportation pipeline, so it can prevent oil fume from spreading around.

The tornado-like cyclone has a strong gathering force, which can control oil fume from spreading around, and the suction of the range hood S can be directed to the source of the fume of the cooktop T, attracting the fume to the fume suction port of the hood body S1, The suction range of the hood body S1 is enlarged, which greatly reduces the power demand of the hood body S1, thereby reducing energy consumption, and also reducing the working noise of the range hood S.

Therefore, according to an embodiment of the present invention, the range hood spin-collection device S2 of the range hood passes the air inlet 100 and the air outlet 10c that communicate with the air duct on the air guide plate 100, so that the airflow from the air guide plate 100 exits. The gas port 10c is discharged, which has strong and strong shearing force on the surrounding air and oil fume, thereby driving the surrounding air and oil fume to flow, and finally tornado-like cyclones are formed, ensuring that the oil fume spirals upward under the strong and powerful suction of the cyclone, which can avoid oil fume Diffusion to the surroundings, expanding the suction range of the range hood S, thereby reducing the power requirements of the range hood S, reducing energy consumption, thereby reducing the working noise of the range hood S, and improving the quality of the range hood S.

Among them, the oil fume spin collection device S2 also includes a fan (not shown), and the fan is connected to the wind deflector 100 for supplying air into the air duct to form an air flow.

That is to say, the oil fume spiral concentrator S2 is mainly composed of the air deflector 100 and a fan. For example, the oil fume spiral concentrator S2 is mainly composed of a plurality of air deflectors 100 and a fan. A fan may be arranged in 100, or the fan is arranged outside a plurality of air deflectors 100, and the plurality of air deflectors 100 share a fan; for example, the oil fume spinner S2 is mainly composed of a wind deflector 100 and a fan In the composition, the air deflector 100 is provided with air outlets 10c arranged in the vertical direction, so that the air flow discharged from the air outlets 10c forms a wind curtain arranged in the vertical direction.

Specifically, when the user is cooking food, the range hood S is turned on to work. The external air flows into the air duct from the air inlet of the air deflector 100 under the action of the fan, and then from the air outlet 10c on the air deflector 100. Exhaust, the airflow discharged from the air outlet 10c on the air deflector 100 drives the surrounding air and oil fume, and has strong and strong shear force on the surrounding air and oil fume. Finally, a tornado is formed in the area around the air deflector 100. Cyclone-shaped cyclones concentrate the oil fume in the middle area between the air deflector 100, the range hood S body, and the cooktop T, that is, the oil fume collects from the surroundings in the middle area. Due to the strength of the airflow, the surrounding oil fume is pushed into the middle area. And spirally rise, and finally discharged from the hood of the range hood S, instead of spreading around.

As a result, the air duct is connected to the fan, thereby forming airflow in the air duct and exhausting from the air outlet 10c of the air deflector 100, driving the air around the air deflector 100 and oil fume to form a tornado-like cyclone, ensuring that oil fume is in the cyclone. Under the action of strong and powerful suction, it can hover upwards to prevent the fume from spreading to the surrounding area and expand the suction range of the range hood S, thereby reducing the power requirements of the range hood S, reducing energy consumption, and thereby reducing the working noise of the range hood S. Improve the quality of the range hood S.

In addition, according to an embodiment of the present invention, the oil fume spinning device S2 also includes a controller (not shown), and the controller is connected to the fan to control the rotation speed of the fan.

Specifically, the oil fume spinning device S2 is mainly composed of a wind deflector 100, a fan, and a controller. The controller is electrically connected to the control board of the fan, and the speed of the fan can be controlled by the controller, thereby adjusting the degree of wind and unit time. The amount of airflow in the interior can further adjust the intensity of the tornado-shaped cyclone formed in the area between the air deflector 100, the range hood S body, and the cooktop T, and the control is flexible.

The range hood has a hood body S1. Optionally, the air deflector 100 extends substantially vertically from the lower edge of the hood body S1 to the cooktop T.

Specifically, the range hood S is mainly composed of the range hood body S1 and the range hood spin-up device S2. The range hood body S1 is installed above the cooktop T and is vertically spaced from the range T. The range hood spin-collection device S2 is arranged below the hood body S1, that is, the hood fusing device S2 is located between the hood body S1 and the cooktop T. The air deflector 100 of the hood fusing device S2 generally forms a plate extending in the vertical direction. The installation method of the fume spin concentrator S2 installed on the hood body S1 can fix the air deflector 100 of the fume spin concentrator S2 on the rear edge of the hood body S1. If the fume spin concentrator S2 is installed on the stove The installation method on the table T can set the air deflector 100 of the fume turning device S2 adjacent to the rear edge of the hood body S1. When the user is cooking, because the fume turning device S2 is located on the hood body S1, The trailing edge is far away from the user, so it will not affect the user's operation, and it will not interfere with other structures. It is safe and convenient in use.

When cooking on the stove T, the user can turn on the range hood S, and at the same time, the range hood S2 can be turned on. The surrounding air enters the air duct of the air deflector 100 of the range hood S2 through the air inlet to form an airflow. Then, the airflow discharged from the air outlet 10c of the air deflector 100 of the oil fume swirling device S2 drives the surrounding air and oil fume to form a tornado-shaped cyclone between the cooktop T and the oil fume suction port.

Specifically, when the range hood S is working, the range hood body S1 sucks oil fume, so that there is a pressure difference between the cooktop T and the range hood body S1 in the up-down direction, that is, when the range hood body S1 is working, it is in the up-down direction. The area near and above the hood body S1 is a low pressure area, and the area near the cooktop T is a high pressure area, so that the pressure difference is transmitted to form a bottom-up thrust. At the same time, the air from the air deflector 100 of the oil fume spinner S2 exits. The converged airflow discharged from the gas port 10c merges the air and oil fume between the cooktop T and the hood body S1, and generates a strong shear force on the confluence area, that is, it meets the conditions of tornado-like cyclone formation, thereby driving The surrounding air and oil fume form a tornado-like cyclone that spirals upward, that is, the airflow discharged from the air outlet 10c of the wind deflector 100 has a strong force to push the surrounding matter into the cyclone and perform a spiral upward movement. Because of the tornado-like cyclone It has a hollow tube shape, with a rapid upward airflow inside, like a natural material rapid transportation pipeline, so it can prevent oil fume from spreading around.

The tornado-like cyclone has a strong gathering force, which can control oil fume from spreading around, and the suction of the range hood S can be directed to the source of the fume of the cooktop T, attracting the fume to the fume suction port of the hood body S1, It is finally discharged from the fume exhaust outlet, which expands the suction range of the hood body S1, greatly reducing the power demand for the hood body S1, thereby reducing energy consumption, and also reducing the working noise of the hood S.

Therefore, according to the range hood S of the embodiment of the present invention, the hood body S1 is provided with the hood spin collection device S2, so that the airflow is discharged from the air outlet 10c of the air deflector 100 of the hood spin collection device S2, The air and oil fume have strong and strong shearing force, which drives the surrounding air and oil fume to flow, and eventually forms a tornado-like cyclone, ensuring that the oil fume spirals upward under the strong and powerful suction of the cyclone, which can prevent the oil fume from spreading to the surrounding area and expanding the smoking The suction range of the range hood S, thereby reducing the power requirements of the range hood S, reducing energy consumption, thereby reducing the working noise of the range hood S, and improving the quality of the range hood S.

In some embodiments of the present invention, the upper end of the air deflector 100 is connected to the lower edge of the rear side of the hood body S1, and the lower end of the air deflector 100 is spaced from the surface of the cooktop T.

That is, the air deflector 100 forms a plate extending in the vertical direction and the upper edge of the air deflector 100 is connected to the rear edge of the lower end of the hood body S1. The lower end of the air deflector 100 is spaced from the surface of the cooktop T. The side surface of the air deflector 100 facing the cooktop T (the front side surface as shown in FIG. 1 and FIG. 3) is provided with an air outlet 10c, so that the airflow can be discharged forward from the air outlet 10c of the air deflector 100. Further, the air and oil fume in the area between the air deflector 100 and the range hood S body, and in the front side of the cooktop T are formed to form a columnar cyclone.

In other specific embodiments of the present invention, the wind deflector 100 is mounted on the cooktop T.

In other words, the air deflector 100 of the oil fume spin device S2 extends a certain distance along the vertical direction between the hood body S1 and the cooktop T, and the lower end of the air deflector 100 of the oil fume spin device S2 is fixed to the upper surface of the cooker T On the rear edge, the upper end of the air deflector 100 of the oil fume swirling device S2 is arranged adjacent to the lower end of the hood body S1, so as to ensure that the airflow discharged from the air outlet 10c of the oil fume swirling device S2 can drive the surrounding air and oil fume. In order to form a tornado-like cyclone between the cooktop T and the oil fume suction inlet, the oil fume is prevented from spreading to the surroundings, and the effect of sucking oil fume is improved.

As a result, the air deflector 100 is disposed between the hood body S1 and the surface of the cooktop T and extends in a vertical direction. The lower end of the air deflector 100 can be fixed on the surface of the cooktop T. The upper end of the plate 100 is spaced from the hood body S1, which is convenient for assembling and disassembling. When the user needs to clean the oil fume spin device S2, it is only necessary to separate the lower end of the air deflector 100 of the oil fume spin device S2 from the surface of the stove T. It can be removed for easy operation; and it is assembled with the stove T as a whole without affecting the layout of the hood body S1.

Advantageously, the upper end of the cyclone is adjacent to the oil fume intake, and the lower end of the cyclone is adjacent to the cooktop T. That is, when the range hood S is in operation, a tornado-like cyclone is formed between the upper side of the cooktop T and the lower side of the oil fume suction port. The cyclone gathers the surrounding air flow (oil fume) and spirals upward, then passes through the oil fume suction port, After entering the smoke machine body S1, it can be finally discharged to the outside after being filtered by the filtering device, which has high feasibility.

In some embodiments of the present invention, the wind deflector 100 is an integrated plate. Specifically, the entire air deflector 100 can be tiled on the wall of the rear wall, or the upper edge of the air deflector 100 can be connected to the lower edge of the hood body S1, or the lower edge of the air deflector 100 and the cooktop can be connected. The back of T is connected, Then, the front side surface of the entire air deflector 100 is provided with an air outlet 10c opening forward to exhaust air forward, and the airflow discharged from the air outlet 10c has a strong and strong shear force on the oil fume from the oil fume, thereby driving the surroundings. The air and oil fume form a cylindrical cyclone extending from the source of the oil fume to the oil fume intake.

As a result, the wind deflector 100 is provided as a whole plate, which can be visually integrated with the hood body S1, which is not only convenient to install, but also easy to clean and improve the user experience. It can also be pasted on the entire wind deflector 100. Decorative pieces such as drawing paper have a decorative effect, improve the aesthetics, and further improve the user experience.

In addition, the wind deflector 100 can protect the wall, facilitate cleaning, and also produce decorative effects. The appearance is beautiful, making the entire kitchen environment more elegant, increasing the user's fun in cooking food, and improving User experience.

In other specific embodiments of the present invention, the wind deflector 100 is a plurality of plates arranged at intervals in the left-right direction. That is to say, the oil fume spinner S2 is mainly composed of a plurality of air deflectors 100 spaced apart from each other in the left and right directions, that is, a plurality of air deflectors 100 are arranged in the same plane and spaced left and right apart. The plate 100 forms a plate extending in the vertical direction. Each air deflector 100 can be disposed at the rear edge of the hood body S1 and defines an air duct therein. Each air deflector 100 also has an air inlet that communicates with the air duct. And the air outlet 10c, for example, each air deflector 100 may be provided with one or more air outlets 10c arranged in a vertical direction, so that the airflow discharged from the air outlet 10c drives the surrounding air and oil fume to flow on the cooktop A cylindrical cyclone is formed between T and the hood body S1.

Optionally, the fan is disposed outside the wind deflector 100 and communicates with the air duct through the wind deflector 100.

Specifically, in this embodiment, the oil fume spinner S2 includes a plurality of air deflectors 100, a fan, and a controller. The controller and the fan are disposed outside the plurality of air deflectors 100 and are electrically connected to control the fan. The fan has multiple air outlets. The multiple air outlets can communicate with the air inlets of multiple air deflectors 100 through air ducts. When the oil fume spin device S2 works, external air flows in the fan. Use it to enter the fan to form high-speed airflow, then enter the air deflectors 100 through multiple air ducts, and finally exit from the air outlets 10c of the multiple air deflectors 100, that is, the multiple air deflectors 100 share a fan. It is possible to ensure that the air volume of each air deflector 100 is equal, thereby ensuring the quality of the tornado-shaped cyclone formed in the front area of the plurality of air deflectors 100, which is beneficial to improving the quality of the range hood S.

Optionally, the fan is arranged in the air duct. In other words, the air deflector 100 forms a hollow structure, and the air inlet and the air outlet 10c are respectively disposed on the wall of the air deflector 100 and are respectively communicated with the air duct of the air deflector 100. Advantageously, the fan is disposed in the air duct and adjacent to it. The air inlet is provided, and the airflow entering the air duct from the air inlet is accelerated by the fan, and is finally discharged from the air outlet 10c. Therefore, the fan is installed in the air duct and is arranged adjacent to the air inlet, which can ensure the suction force of the fan 200 to the external airflow, thereby ensuring the air flow entering the air duct 10a, and avoiding entering the air duct 10a. The airflow is attenuated between the fan 200 and the air inlet, reducing airflow loss.

According to an embodiment of the present invention, the air outlet 10c is at least one slot and / or multiple holes.

For example, the air outlet 10c may be formed as a slot extending in the vertical direction, wherein the number of the slot may be one or more, the slot is communicated with the air duct, and the surrounding air enters the fume spin device S2 through the air inlet. The airflow is formed in the air duct, and then the airflow exhausted from the slot of the oil fume swirling device S2 forms a wind curtain extending in a vertical direction. The air curtain drives the surrounding air and oil fume to flow between the cooktop T and the oil fume suction port. A tornado-like cyclone is formed.

For another example, the air outlets 10c may form a plurality of holes spaced apart in a vertical direction. The holes may be arranged in a row extending in the vertical direction, or may be arranged in multiple rows and multiple rows. Cooperate to drive the surrounding air and oil fume to form a tornado-like cyclone between the cooktop T and the oil fume intake.

In some specific embodiments of the present invention, the air outlets 10c are a row, that is, the air deflector 100 is an integrated plate, and the air outlets 10c on the air deflector 100 are located between two furnace eyes and exhaust forward, If the two stove eyes on the stove T work at the same time, the middle air outlet 10c of the air deflector 100 can be shared, that is, the airflow exhausted from the middle air outlet 10c forms a shear force on the oil fume sources on both sides, so that the stove T Two tornado-shaped cyclones are formed between the two furnace eyes and the hood body S1 to ensure the hood effect of the range hood S.

In other specific embodiments of the present invention, the air outlets 10c are multiple rows, and adjacent rows are spaced apart from each other in the left-right direction.

Specifically, the projection of the hood body S1 of the range hood S on the horizontal plane is substantially rectangular, and the air deflector 100 of the range hood spin-collection device S2 of the range hood forms a rectangular plate extending in the vertical direction. The rear part of the lower end of the hood body S1 is spaced from each other in the left-right direction, and the air deflector 100 is provided with a plurality of air ports 10c spaced apart in the left-right direction.

For example, the range hood concentrator S2 of a range hood includes two spaced-apart air deflectors 100, in which the air deflector 100 on the left and the right deflector 100 can respectively wind out to the corresponding positions. The source of soot at the furnace mouth forms a shearing force along the tangential direction to form a columnar cyclone, thereby improving the effect of the soot of the range hood S.

If there are two stove openings on the cooktop T, the air outlet 10c of the left air baffle plate 100 of the two air baffle plates 100 is located on the left side of the leftmost stove opening on the cooktop T, and the air outlet of the right air baffle plate 100 10c is located on the right side of the rightmost oven port on the stove top T. The two air deflectors 100 respectively emit air. If the user uses two ovens to cook food at the same time, the air from the two air deflectors 100 can be driven separately. The surrounding air and oil fume flow, thereby forming two tornado-like cyclones between the two stove ports of the cooktop T and the hood body S1, thereby ensuring the effect of the range hood of the range hood S.

For another example, the air deflector 100 is an integrated plate. The front side of the air deflector 100 is provided with two rows of air outlets 10c spaced apart in the left-right direction. Among them, the air outlet 10c on the left side faces forward and is located on the left side of the furnace. On the left side, the air outlet 10c on the right side opens forward and is on the right side of the right furnace mouth.

When the range hood is operating, the airflow from the left air outlet 10c of the air deflector 100 can form a strong shear force on the fume source on the left side and the surrounding air. Finally, the left side of the fume source on the left side and the hood body S1 A tornado-like cyclone is formed between them; the airflow from the air outlet 10c on the right side of the wind deflector 100 can form a strong and strong shear force on the soot source and the surrounding air on the right side. A tornado-like cyclone is formed between the bodies S1.

It should be explained here that the rear portion of each air deflector 100 located on the surface of the cooktop T can be understood as the area between the horizontal line where the center of each oven mouth is located and the rear edge of the cooktop T, that is, on the surface of the cooktop T In the front-to-rear direction, each air deflector 100 is located in an area enclosed by an imaginary straight line formed by the centers of a plurality of furnace mouths and the rear edge of the surface of the cooktop T. The air outlet 10c on the air deflector 100 The opening direction can be set according to the design requirements to ensure that the airflow discharged from the air outlet 10c can form a tangential shear force on the source of oil fume and the surrounding air, thereby driving the oil fume and the surrounding air to form a cylindrical cyclone that spirals upward.

The following specifically describes a range hood spin-up device S2 of a range hood according to an embodiment of the present invention in combination with a plurality of embodiments.
