Because of the inability to move smoothly, the inhalation, such as a decrease in incidence is caused. The present invention is configured to separate the outside air supply fan with the odor intake fan in the stove hood, to configure the air control device on the duct of the outside air intake fan to regulate and supply the grease filter and the air curtain, and to heat the intake external cold air in the stove Heated by passing the grease filter heated by the high temperature exhaust air, the air curtain is formed by the exhaust to a certain temperature warmed state to prevent the closing according to the temperature difference and to save power, and the air curtain to the desired position because the temperature difference is small It is devised to effectively intake and exhaust the odor generated by preventing the formation and pressure difference between indoor and outdoor.

Description

Range hood for air cover with air curtain

The present invention relates to a stove hood, and in particular, the outside cold inlet air is sucked into the outside air supply fan and radiated into the room by an outside air supply regulator. The present invention relates to a supply / exhaust range hood provided with an air curtain to increase odor exhaust and air curtain effects.

As is well known, the conventional stove hood is installed at a certain height at the top of the gas stove of the kitchen, and the stove hood is operated by turning on / off the power to discharge the odor and heat generated from the heated food when cooking using the stove. As the motor in the hood rotates the exhaust fan, the odor and heat generated in the lower part of the hood are sucked and discharged through the exhaust duct.

Such a conventional range hood has a large distance from the hood and the odor generating position, that is, the heating part, and especially in an open state, so that even if a large suction amount is provided in the exhaust fan of the hood, the suction amount is limited. As indoor outdoor air in close proximity to the hood is sucked first, a problem arises in that a long distance odor is not inhaled and is not discharged. However, a fundamental problem in the range hood is that the suction force is limited by the air pressure difference between the indoor and outdoor. The above problem is caused by many more factors.

As a result, even though an expensive hood is installed, the air intake effect is low as described above, and in reality, it is a solution to release smoke and odor during cooking by opening a window or opening a door by relying on the hood. It is losing.

In order to improve the shortcomings of the range hood, the air curtain has been configured in the hood.

For example, the Korean Utility Model Registration No. 0018690 constitutes a odor intake fan that inhales and exhausts odors into the body of the stove hood, and a separate air supply fan is formed on the front of the hood body to suck in the warm air in the room. The air curtain is constituted by exhausting it again.

Accordingly, the air supply fan which is operated independently regardless of the odor intake fan draws the indoor air through the grille of the body and discharges it to the lower part of the body to derive the configuration and the effect that the air curtain is discharged to form the air in front of the hood.

This configuration will have the following problems.

In other words, in the modern society, a gap such as a double door is sealed in a house to prevent noise and maximize the heating effect.

Accordingly, the above-mentioned design is particularly sealed in the winter in a state in which the window is closed, so that the air pressure difference occurs in the interior when the indoor air is sucked from the hood while the intake air is minimized.

As a result, the odor to be sucked into the exhaust fan is greatly reduced by being sucked into the exhaust fan, which hinders the hood function and spreads the odor rapidly into the room by the differential pressure.

In addition, in the state where the differential pressure as described above, the air curtain is lowered and collides with the hot air heated in the lower range, and is directly raised to the intake air of the odor intake fan by the differential pressure, so that the air curtain is moved to draw a small arc. The effect of the curtain is to have a disadvantage that is largely limited disadvantages can not obtain the desired effect.

In order to improve the problem of the pre-registration proposal, Korean Utility Model Registration No. 20-0164752 consists of a range hood as the first and second class air chambers to intake air into each fan, and the indoor intake air is first-class by the air direction control plate. Through the fan in the air chamber, the air that was discharged through the fan in the second air-supply chamber was introduced into the room through the temperature exchange plate and the air purification plate to purify the indoor air.

As mentioned above, the pre-registration proposal has the characteristics of collecting foreign substances in the air by the temperature exchange plate and heating by the temperature exchange plate together with the inflow of external air, but as described above, it is difficult to manufacture due to the complicated structure, and especially high production cost. It has the disadvantage of taking it.

In addition, even in the configuration that passes through the temperature exchange plate and the air purification plate, the flow path is complicated, and the movement of air is not smooth, resulting in a decrease in suction amount and the like.

The present invention is designed to solve the above problems, and in particular, the outside hood with a odor absorbing fan in the stove hood, but separately configured,

The air control device is configured on the duct of the outside air intake fan, and is supplied by adjusting with grease filter and air curtain

The air curtain is formed by exhausting the intake external cold air through a heated grease filter for removing oil generated from food, smoke, etc. It is an object of the present invention to achieve the effect of preventing closure and saving power according to the conventional temperature difference, and to effectively inhale and remove the odor generated by preventing the formation of air curtain to the desired position and the pressure difference between indoor and outdoor due to the small temperature difference.

As shown in FIGS. 2 and 3, a grease filter 30 of the present invention is constructed in a range hood to prepare a sink for a kitchen sink 15. Range hood 100 is configured to the upper portion and the hood hood 100 to the odor intake exhaust fan 10 connected to the exhaust duct 11 to the drive motor (or integrated with the fan not shown) to the user needs Turn on / off the power supply to start the range hood.

That is, when cooking food in the stove 15 of the kitchen, odors such as heat generated by the heating of the stove 15 and various odors generated from the food are generated, and at this time, the hood is operated to remove the odor. do.

For example, when the control on / off switch of the stove hood 100 is turned on, the odor intake exhaust fan 10 is operated and the air supply fan 20 is driven together by the control or is separated. Although operated by an on / off switch, it will be described in the present embodiment that the air supply fan 20 is set to the on state together.

At this time, before operating the range hood 100, the current season is determined by the difference between the indoor temperature due to the winter and summer, whether the air used in the air curtain is to use the outdoor air without heating or heated air by heat exchange It is determined whether or not to form an air curtain by operating the operation section 50 of the operation panel 101 of the range hood,

That is, when the air of the air curtain to the cold air in the summer season when the operation 50 is rotated as shown in Figure 5 the wire 48 is interlocked by the operation period 50 as shown in Figure 5 The working piece 44, which is hinged while the fixed working piece 44 is interlocked, moves the opening and closing plate 43 of the other end to the fastening pipe 38 of the grease filter 30 for winter at the summer outlet, thereby moving the fastening pipe ( 38) At the same time closing the lateral outlet opening the open air fastening pipe 36 side.

Accordingly, the outdoor air sucked into the outside air supply fan 20 is supplied to the external air fastening pipe 36 from the "ㅏ" -shaped control pipe 42, and the air supplied is discharged together with the air freshening pipe 36. The air curtain is radiated to the front of the range hood by radiating to the bent air guide plate 35 lowered from the upper assembly panel 31 of the grease filter 30 and spreading to both sides along the bent surface. It is configured to prevent the smell of the inside of the hood hood to leak out into the room and with this, by supplementing the amount of outdoor air discharged there is no air pressure difference between the outside is made easy to discharge the odor.

In addition, when there is a temperature difference between the indoor and outdoor in the winter, when the operation unit 50 is rotated, as shown in FIG. 5, the wire 48 is interlocked by the operation unit 50 as shown in FIG. The working piece 44 hinged while interlocking with each other moves the opening / closing plate 43 of the other end from the winter outlet to the fastening pipe 38 of the grease filter 30 for the summer, so that the outlet of the fastening pipe 38 is lateral. Opening and closing plate 43 moved with opening the closing the air fastening pipe (36) side.

Accordingly, the outdoor air sucked into the outside air supply fan 20 is supplied to the grease filter 30 from the " 자 " shaped control pipe 42, and the supplied air is heated in the heating chamber 37 of the grease filter 30. Will be configured to air curtain while being radiated to the air spinning ball 33 through.

At this time, the outdoor unit is heated to a predetermined temperature while passing through the heating chamber 37 of the grease filter 30 and exchanging the heating heat of the heat exchanger tube 34 discharging the odor and high heat, and the air thus warmed is air-spinning Radiating to 33 to minimize the indoor temperature difference is to improve the conventional closure by the temperature difference.

The suction force is exerted by the high-speed rotation of the odor intake exhaust fan 10 which rotates at high speed by the above, and the suction force is lowered through the plurality of heat exchange tubes 34 fastened up and down of the grease filter 30. At this time, the odor of the upper part is sucked in. At this time, the odor passing through the heat exchange tube 34 filters the food oil, etc. in the grease filter 30, and heat exchange tube 34 by heat exchange with the heat exchange tube 34. This is to be released to the outside by the intake force of the odor intake exhaust fan 10 while being heated.

As described above, the air curtain radiated to the air spinning hole 33 significantly reduces the difference with the room temperature, thereby minimizing the wind direction conversion due to the temperature difference and the collision with the high temperature rising from the stove, and thus the air curtain is formed in the desired position. The rising odor is to be easily inhaled by the odor intake exhaust fan 10 as the rising suction input while preventing the discharge to the outside of the hood.

In addition, the present invention also obtains the effect of providing a more comfortable kitchen by radiating fresh cold outdoor air as it is in summer, and the air curtain shows only the front side in the drawing.
