Description

Range hood that prevents oil fumes from overflowing

technical field

The utility model relates to an oil fume removing device, in particular to a range hood which utilizes an air curtain generator to generate an air curtain to achieve the effect of isolating oil fume.

Background technique

The range hood is usually installed in the kitchen. It can remove the oily fume generated during cooking, and prevent the oily fume from remaining on the kitchen wall and causing oil stains, or being inhaled by the human body to affect the health of the body.

The main structure of the range hood in the prior art is that an exhaust port is formed on the top of the casing, a smoke inlet opening is formed on the bottom of the casing, and an intake fan and a filter screen are arranged inside the casing. , the user can start the intake fan to attract the oily fume from the opening of the smoke inlet to the filter screen, the filter screen absorbs the oil particles and impurities in the oily fume, and then discharges it through the exhaust port.

However, the presence of oily fume in the space will cause diffusion. If the food is only cooked on a low fire, less oily fume will be produced, and the oily fume produced can be smoothly drawn away by the intake fan, and the diffusion phenomenon is not obvious; if the food is cooked on a high fire When deep-frying or fast-frying, a large amount of oily smoke will be generated instantly. At this time, the intake fan can only extract part of the oily smoke, and the rest will spread to the surroundings. The diffusion phenomenon is more obvious, so there will still be oil stains remaining in the kitchen There are problems such as being in the space or being inhaled by the human body and affecting health. Therefore, the range hood of the prior art has the disadvantage of being unable to effectively prevent the diffusion of the oil fume.

Utility model content

In view of the problem that the range hood in the prior art cannot effectively prevent the diffusion of oil fume, resulting in oil stains remaining in the kitchen space or being inhaled by the human body and affecting health, the utility model improves these problems through the following technical means.

The utility model relates to a range hood which can prevent oil smoke from overflowing, which comprises a row of range hood bodies, a plurality of flow dividers and an air curtain generator;

The range hood body has a casing, the casing is a hollow casing, an air intake fan is arranged inside, a smoke inlet opening is formed at the bottom of the casing, and an exhaust port is formed at the top, so The smoke inlet opening communicates with the exhaust port and the intake fan; the splitter is a hollow shell, and an air outlet is formed at the bottom of the shell, and each splitter is respectively arranged on three adjacent inner wall surfaces of the casing. The air outlet is set facing downward; the air curtain generator is set on the casing, and communicates with each flow divider through an air flow duct.

Preferably, the diameter of the air outlet of the splitter is smaller than the inner diameter of the splitter housing.

Preferably, the flow divider is an elongated shell, the long axis of the flow divider is arranged transversely inside the casing, and a plurality of deflectors are arranged inside the flow divider. One side edge is connected to the inner wall surface of the flow divider, and the bottom ends of each deflector are respectively bent towards the two ends of the long axis of the flow divider.

Preferably, an air guide tube is arranged on the top surface of the flow divider along its long axis, the air guide tube communicates with the air flow duct of the air curtain generator, and a plurality of air holes are formed at the bottom end of the air guide tube. Each air hole communicates with the inside of the flow divider.

Preferably, the range hood that can prevent oil fumes from overflowing in the present utility model includes a three-diverter; the bottom end of the casing is a hollow rectangle, and the three-diverters are respectively arranged on three adjacent inner wall surfaces of the casing superior.

Through the above-mentioned technical means, a flow divider is provided on the inner side wall of the casing, and the air curtain generator communicates with each flow divider with an air flow pipe, which can generate air flow and guide it to each flow divider with an air flow pipe, and pass through each flow guide The flow sheet divides the airflow evenly and blows it downward from the air outlet to form an air curtain that can isolate the oil fume from overflowing. Each air curtain and the kitchen wall where the range hood body is installed form a shielding space, which can prevent the cooking. The oily fume will not spill out of the shielded space, effectively preventing the oily fume from spreading laterally, so that the oily fume can pass through the intake fan and be discharged from the exhaust port, thereby achieving the purpose of providing users with a clean kitchen and preventing users from inhaling the oily fume.

Detailed ways

Below, in conjunction with the accompanying drawings and preferred embodiments of the utility model, the technical means adopted by the utility model to achieve the intended purpose of the utility model will be further elaborated.

The utility model is a range hood that can prevent oil fumes from overflowing, as shown in Figure 1, it includes a row of range hood bodies 10, three diverters 20 and an air curtain generator 30;

The range hood body 10 has a casing 11, the top of the casing 11 is formed with an exhaust port 111, the bottom of the casing 11 is formed with a smoke inlet opening 112, and the bottom of the casing 11 is provided with an outlet connected to the exhaust port 111. At least one intake fan and at least one filter screen (not shown in the figure), the smoke inlet opening 112, the exhaust port 111 and the intake fan communicate with each other. As shown in the preferred embodiment in the figure, the bottom side wall of the casing 11 formed as a hollow rectangular body;

The flow divider 20 is a hollow shell, and an air outlet 201 is formed at the bottom of the casing. The diameter of the air outlet 201 is smaller than the inner diameter of the casing of the flow divider 20. Each flow divider 20 is respectively arranged on three adjacent inner wall surfaces of the casing 10. Above, the air outlet 201 is set facing downward, please refer to Fig. 2 and Fig. 3. In the specific embodiment shown in the figure, the flow divider 20 is an elongated shell, and the two side walls of the shell are formed between The spacing is tapered from the top end to the bottom end, and the flow divider 20 is arranged horizontally inside the casing 10 with the long axis, and a plurality of flow guide vanes 21 are arranged inside the flow divider 20, and the flow guide vanes 21 are connected by one side edge of the sheet body On the inner side wall of the flow divider 20 , the bottom ends of the deflectors 21 are bent towards both ends of the long axis of the flow divider 20 .

The air curtain generator 30 is a blower, which is installed on the casing 11 , and the air curtain generator 30 communicates with each flow divider 20 through the airflow duct 31 . In the preferred embodiment shown in the figure, it is further provided with three air guide tubes 32, each air guide tube 32 is respectively arranged on the top surface of each flow divider 20 and arranged along its long axis direction, the air guide tube 32 is a hollow tube The bottom end of the body is formed with a plurality of air holes, and each air hole communicates with the inside of the flow divider 20, and the middle section of the pipe body communicates with the air flow duct 31.
