Technical Field

The present invention relates to an intake and an air supply of a range hood used in a kitchen, and to an intake range hood having an intake and an air supply at the same time and a cooling means provided with a cooling means.

Prior art

In general, when food is cooked in a kitchen, odors and smoke are inevitably generated.

Therefore, if there is no separate exhaust means, the smell and smoke generated during cooking will diffuse into the room, contaminating the air in the room, and the inconvenience of having to open and ventilate the window frequently is accompanied. It took a considerable amount of time to discharge completely, which did not provide an efficient method for air purification.

In order to solve this problem, by installing an exhaust duct equipped with an exhaust fan in the upper part of the cooking facilities of the kitchen, such as a gas range, various smells, smoke, and cooking heat generated during cooking are discharged to the outside through the exhaust duct. Although this is used, there is a significant distance between the cooking facilities of the kitchen and the exhaust duct has a problem that various pollution sources generated during cooking can not be sucked through the exhaust duct quickly and diffuse into the room to contaminate the indoor air.

In order to overcome the limitation of the method of removing various pollutants generated during cooking by a simple exhaust method, a range hood has been created to prevent the spread of the pollutants indoors by forming an air curtain (air curtain). Air film is formed by spraying air downward toward the cooking facility (hereinafter referred to as 'downward method') or by spraying air upward toward the range hood in the cooking facility (hereinafter referred to as 'upward method'). In other words, the air barrier blocks the various pollutants from cooking facilities that are mostly discharged through the exhaust pipe and diffuse into the room.

However, in the case of such a conventional air curtain (air curtain) there was a problem that does not effectively block the pollutant generated during cooking because the blocking effect is less than expected.

In other words, in the case of the downward method, as the jet pressure of the jet air forming the air membrane approaches the cooking facility, it is rapidly reduced by the rising hot air and various pollutants generated in the cooking facility. There was a problem that a significant portion spread into the room.

Also, in the case of the upward method, as the rising blown air moves to the upper part, the blowing pressure drops sharply due to the effect of gravity, so that the air layer is not properly formed in the upper part, and the rising air flows with the hot air generated in the cooking facility. In particular, the face part) had a problem causing severe discomfort.

The object of the present invention created to solve the above problems is as follows.

First, it is an object of the present invention to provide a means for preventing the spread of various pollution sources generated during cooking.

Secondly, it is another object of the present invention to provide a means for collecting various pollutants generated during cooking and at the same time forming an air curtain (air curtain) surrounding the collected pollutant.

Third, another object of the present invention is to provide a means for descending the air flow forming the air film while turning in a predetermined direction.

Fourthly, another object of the present invention is to provide a means for forming a descending air flow to turn and also ascending the air flow including a source of pollution rising inside the down air while turning in a predetermined direction under the influence of the air flow.

Fifth, another object of the present invention is to provide a means for adjusting the turning direction of the downdraft.

Sixth, another object of the present invention is to provide a means capable of heating a raised air stream at the same time as providing a cooled down air stream.

The configuration of the present invention created to achieve the above object is as follows.

The present invention provides air intake means for collecting contaminated air in a room; And air supply means for ejecting downdraft air flow around the air intake means. In the range hood, the air intake means comprises: an intake pipe serving as a passage of the collected air; And an intake fan for introducing air into the intake pipe, wherein the air supply means includes an air supply pipe installed around the intake pipe; An air supply fan for ejecting a downdraft through the air supply pipe; And cooling means installed in the air supply pipe to cool the downdraft, wherein the downdraft descends while maintaining a downward slope in a predetermined direction to impart a turning force to the updraft. It is related with the provided rise range hood.

Hereinafter, with reference to the accompanying drawings will be described in detail a specific embodiment of the present invention.

2 is a front sectional view of a specific embodiment of the present invention, and includes an intake means 100 for collecting contaminated air in a room, and an air supply means 200 for ejecting a downdraft around the intake means 100. In the range hood, the intake means 100 includes an intake pipe 110 which is a passage of the collected air and an intake fan 120 for introducing air into the intake pipe 110, and the air supply means 200 includes the intake pipe. Cooling means for cooling the downdraft is installed in the air supply pipe 210 is installed around the 110, the air supply fan 220 for ejecting the downdraft through the air supply pipe 210 and the air supply pipe 210 ( 300).

3 is a side cross-sectional view of a specific embodiment of the present invention. Referring to FIGS. 2 and 3, an air supply means 200 is provided around the intake means 100, and a cooling means is provided inside the air supply means 200. 300).

As shown in FIGS. 2 and 3, the intake means 100 includes an intake pipe 110 serving as a passage of air collected and ascended, and an intake fan 120 serving as a power source for introducing air into the intake pipe 110. do.

The intake pipe 110 serves as a passage of the collected air, and there is no particular limitation on the shape and size thereof, and the intake pipe 110 may be a structure capable of effectively collecting and passing air including a contaminated source that is installed at an upper portion of the cooking facility.

Therefore, it is desirable to design as wide a cross-sectional area of the inlet as possible as shown in Figs.

The intake fan 120 serves as a power source for raising the air including the pollution source to the intake pipe 110. There is no restriction in addition to the shape or type of the intake fan 120, and the intake fan 120 having a predetermined shape may be selected and used in consideration of the shape and size of the range hood.

The air supply means 200 is an air supply pipe 210 installed around the intake pipe 110 as shown in FIGS. 2 and 3, an air supply fan 220 for ejecting the downdraft air through the air supply pipe 210, And cooling means 300 installed inside the air supply pipe 210 to cool the downdraft.

The function of the air supply means 200 forms an air curtain (air curtain) so that the pollutant generated in the cooking facility does not diffuse into the room, and the air containing the pollutant rises inside the formed air membrane so as to flow into the intake pipe 110. do.

The air supply pipe 210 ejects air descending around the intake pipe 110 to form an air film around the air intake pipe 110. Therefore, in order to reliably form the air film, the air supply pipe 210 preferably has a structure that completely surrounds the circumference of the intake pipe 110 as shown in FIGS. 2 and 3.

The air supply fan 220 serves as a power source for ejecting air descending through the air supply pipe 210 at a predetermined pressure. There is no separate restriction on the shape or type of the air supply fan 220, and the air supply fan 220 may be selected and used in consideration of the shape and size of the intake pipe 110, and FIGS. 2 and 3. As shown in the drawings, a plurality of air supply fans 220 may be used.

The cooling means 300 is installed inside the air supply fan 220 to lower the temperature of the air descending through the air supply pipe 210 as shown in FIGS. 2 and 3.

When the cooling means 300 is provided as described above, the temperature of the air descending through the air supply pipe 210 is lowered, thereby facilitating the formation of the downdraft. Therefore, the air film can be formed more firmly.

4 shows a thermoelectric element as a specific embodiment of the cooling means 300.

Thermoelectric element is a generic term for a device using a phenomenon in which heat and electricity are converted to each other. Here, a device using a Peltier effect is applied.

The Peltier effect means that the endothermic phenomenon occurs at one terminal and the exothermic phenomenon occurs at the other terminal according to the direction of the current when current is applied by connecting the two ends of different kinds of metals.

Therefore, as shown in FIGS. 2 to 4, the heat absorbing terminal 310 of the thermoelectric element used as the cooling means 300 is installed in the air supply pipe 210, and the heat generating terminal 320 of the thermoelectric element is the intake pipe 110. Is installed on.

As shown in FIG. 4, in the thermoelectric element, which is a specific embodiment of the cooling means 300, a plurality of heat exchange fins 330 are provided at predetermined intervals in order to increase the heat exchange effect.

Therefore, the air passing through the air supply pipe 210 is deprived of the heat contained in the heat exchange fin 330 while contacting the heat exchange fin 330 of the heat absorbing terminal 310, the temperature of the air is lowered.

In addition, the air rising through the intake pipe 110 contacts the heat exchange fins 330 installed in the intake pipe 110, and receives heat from the heat exchange fins 330, thereby increasing the temperature of the air.

As shown in FIG. 4, a plurality of heat exchange fins 330 are arranged in a predetermined direction while maintaining a predetermined interval, and a direction in which air is blown through the air supply pipe 210 is arranged in the heat exchange fins 330. It depends on the direction. In other words, when the airflow descending through the air supply pipe 210 meets the heat exchange fins 330, the downdraft flows along the arrangement direction of the heat exchange fins 330, so that heat exchange occurs between the downdraft and the endothermic terminal 310. As a result, the downdraft passing through the heat exchange fins 330 is not only lowered in temperature but also flows along the arrangement direction of the heat exchange fins 330.

Therefore, the downdraft flowed from the air supply pipe 210 is ejected along the arrangement direction of the heat exchange fins 330.

As the jet direction of the downdraft is determined along the arrangement direction of the heat exchange fin 330, the downdraft flows downward while turning in a predetermined direction as shown in FIG.

That is, the heat exchange fins 330 of the heat absorption terminal 310 are arranged in a predetermined direction so as to guide the flow of air to each of the front, rear, left and right inside the air supply pipe 210 and pass through each heat absorption terminal 310. One downdraft can be lowered while maintaining a downward slope in a predetermined direction as shown in FIG.

In addition, although not shown in detail in the accompanying drawings, the heat absorbing terminal 310 of the thermoelectric element may be installed to be rotatable at a predetermined angle.

In other words, the endothermic terminal can be rotated at a predetermined angle as shown in FIGS. 2 and 3 so as to change the arrangement direction of the heat exchange fins 330 of the endothermic terminal.

Therefore, the down slope of the downdraft can be adjusted according to the user's choice.

As shown in FIG. 2 and FIG. 3, a heat insulating partition 400 is installed between the intake pipe 110 and the air supply pipe 210.

The thermal insulation partition 400 prevents heat transfer between the air of the air supply pipe 210 cooled by the heat absorbing terminal 310 and the air of the air intake pipe 110 heated by the heat generating terminal 320.

In other words, the air of the air supply pipe 210 cooled by the heat absorption terminal 310 blocks the heat transfer from the intake pipe 110.

The shape or type of the insulation barrier 400 is not particularly limited and may be freely selected and applied to an insulation material that can effectively block heat transfer.

5, a variable grill 500 is shown.

The variable grill 500 is installed at the outlet end of the air supply pipe 210 as shown in FIG. 5 and has a structure capable of rotating at a predetermined angle.

Therefore, the advancing direction of the descending air stream ejected from the air supply pipe 210 can be adjusted within a predetermined range.

In other words, the guide vane 510 constituting the variable grill 500 may be rotated at a predetermined angle to induce the downdraft in a direction desired by the user.

When the variable grill 500 is provided as described above, the direction in which the air flows down through the air supply pipe 210 is more reliably matched with the direction in which the heat exchange fins 330 are aligned with the direction in which the guide vanes 510 are arranged. It can be controlled, even if the arrangement of the heat exchange fin 330 can not be rotated at a predetermined angle can be directed to the desired direction of the downward slope of the downdraft only by the operation of the variable grill 500.

On the other hand, even when such a variable grill 500 is not provided, the downdrafts passing through the respective heat absorbing terminals 310 are arranged by arranging the heat exchange fins 330 of the heat absorbing terminals 310 in a predetermined direction as described above. Of course, as shown in Figure 1 it can be induced to maintain the downward slope in a predetermined direction.

As such, the variable grill 500 plays a role of controlling the downward slope of the downdraft.

That is, the overall downward inclination direction of the downdraft is determined by adjusting the arrangement direction of the heat exchange fins 330, and more precise direction adjustment is performed using the variable grill 500.

Technical effects according to the present invention of the above configuration is as follows.

First, it is possible to provide a means for preventing the spread of various pollutants generated during cooking into the room.

In other words, the present invention is not merely to collect and remove various pollutants generated during cooking, but to form an air film through an air supply pipe so that the pollutant does not diffuse into the room. It is blocked by the air film and is prevented from spreading indoors.

Secondly, it is possible to provide a means for collecting various pollutants generated during cooking and at the same time forming an air curtain (air curtain) surrounding the collected pollutant.

In other words, the downdraft discharged by the air supply pipe 210 forms an air film that surrounds the cooking facility and the intake pipe 110 so that most of the various pollutants generated in the cooking facility can be removed to the intake pipe. .

Third, it is possible to provide a means for the descending airflow forming the air film to descend while maintaining a downward slope in a predetermined direction.

In other words, according to the arrangement direction of the heat exchange fins 330 and the arrangement direction of the guide vane 510 of the variable grill 500, the downward inclination direction of the downdraft jetted from the air supply pipe 210 is controlled.

Fourth, the descending airflow descends while maintaining a downward slope in a predetermined direction, thereby giving a turning force to the rising airflow including the pollutant source rising inside the descending airflow.

In other words, the descending air flows while maintaining a downward slope around the upward air flow. The air flow including the pollutant rising therein is determined by the Coriolis effect caused by the downward air flow and the rotation of the earth. As you turn in the direction of the will rise.

Fifth, it is possible to provide a means for adjusting the downward inclination direction of the downdraft.

In other words, by configuring the heat exchange fins 330 and the guide vanes 510 to be rotatable within a predetermined range, the downward inclination direction of the downdraft can be adjusted.

Sixth, it is possible to provide a means capable of heating a raised air stream which is simultaneously provided with a cooled down air stream.

In other words, the heat absorbing terminal 310 of the thermoelectric element is installed in the air supply pipe 210, and the heat generating terminal 320 of the thermoelectric element is arranged in the intake pipe 110 to supply cooled downdrafts and to be collected into the intake pipe 110. The rising airflow to be heated can be heated.

In this way, the low temperature of the air flow and the high temperature and high humidity of the rising air to interact to induce the rise of the phenomenon can maximize the capture effect of contaminated air.

The dragon rise phenomenon is a phenomenon in which a columnar or funnel-like cloud accompanied by a severe whirlwind reaches to the ground or the sea surface from the cumulonimbus cloud, and is a mixture of water droplets, dust or sand rising from the sea surface or the ground. It is called as a yongoreum.

This phenomenon is caused by the latent heat in the cumulus cloud heating the air in the cloud to generate a strong rising air, the rising air is rotated by the Coriolis effect by the rotation of the earth to suck the surrounding air. In other words, the convergence phenomenon in which the surrounding air is sucked into the cumulonimbus by the strong rising air that rises while turning is the rising phenomenon.

According to the present invention, a turning force is applied to the updraft by a descending downdraft while maintaining a downward slope in a predetermined direction to induce rotation of the updraft, and a heating terminal 320 is installed inside the intake pipe 110 to raise the updraft. Heating to generate artificial melt rise phenomenon.

When such an artificial rise rises, the rising air strongly sucks the surrounding air, and as a result, the collection effect of various pollutants can be maximized.
