Description

Hood movable range hood using infrared sensor {HOOD MOVING TYPE RANGE HOOD USING INFRARED SENSOR}

The present invention relates to a lazy hood, and more particularly, to a hood movable range hood using an infrared sensor suitable for preventing steam, smoke, etc. generated during cooking of food from leaking out of the hood and leaking into the food making facility or the user. will be.

In general, the range hood installed in the kitchen is for discharging gas, steam, smoke, etc. generated during food cooking to the outside.

Such a range hood is fixedly mounted to a gas range and a predetermined height and has the following disadvantages.

First, the gas generated when cooking the food is spread upward and gradually spread to the surroundings. At this time, the gas is sucked into the hood by riding on the wall to the front (user side) and contaminates the indoor air.

There is a method of lowering the height of the hood for this purpose, but this has the disadvantage that the user is limited by the space to be provided for cooking food.

The present invention is to solve the above problems and problems, the hood using an infrared sensor suitable for preventing the steam, smoke, etc. generated during cooking of food to escape from the hood to the user making food or indoors. The object is to provide a movable range hood.

Specific means of the present invention for achieving the above object,

In the range hood for discharging the gas generated when cooking food in the kitchen,

A hood 20 having a hood chamber 22 extended downwardly and an outlet 24 communicating with the hood chamber 22;

A centrifugal fan (30) and a fan motor (32) mounted on an upper portion of the hood (20) to forcibly suck the gas introduced into the hood chamber (22) and discharge the gas into the outlet (24) of the hood (20);

Sensing means for sensing the presence of a person in front of the hood 20;

A transfer motor 40 mounted on the front surface of the hood 20 to forward and reverse rotation according to the sensing means;

A transfer screw 50 directly connected to the transfer motor 40;

Screwed to the transfer screw 50 is characterized in that it comprises a gas blocking plate 46 to move up and down in front of the hood chamber 22 in accordance with the rotation direction of the output end of the transfer motor 40.

1 and 2 are side cross-sectional views of a range hood according to an embodiment of the present invention, in which a person is approaching or retracted from the range hood.

<Explanation of symbols for main parts of drawing>

24: outlet 30: centrifugal fan

32: fan motor 40: transfer motor

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 and 2 are side cross-sectional views of the range hood according to the embodiment of the present invention when the person approaches the range hood or withdraws from the hood side.

As shown, reference numeral 20 denotes a hood, and the hood 20 includes a hood chamber 22 which is enlarged downwardly and an outlet 24 in communication with the hood chamber 22.

The centrifugal fan 30 and the fan to the upper portion of the hood 20 to forcibly suck the gas (food smell, steam, etc.) coming up to the hood chamber 22 side when cooking food to the outlet 24 of the hood 20 The motor 32 is mounted.

In addition, an infrared sensor 60 is installed on the front surface of the hood 20 as a sensing means for sensing the presence of a person and controlling the rotation of the transfer motor 40 to be described later.

A motor bracket 44 is mounted on an upper portion of the front of the hood 20, and the motor bracket 44 is fixedly installed with a transfer motor 40 that is rotated forward and backward according to the infrared sensor 60. One end of the transfer screw 50 is directly connected to the transfer motor 40, the other end of the transfer screw 50 is rotatably supported by the bracket 46, and the transfer motor 40 is connected to the transfer screw 50. Gas blocking plate 46 which moves up and down from the inclined front surface of the hood chamber 22 in accordance with the rotation direction of the output end of the) is connected by screwing.

The operating state of this embodiment configured as described above will be described.

When a person approaches the range hood 10 side as shown in FIG. 1, the infrared sensor 60 detects this, and when the feed motor 40 is driven to rotate the feed screw 50 forward, The gas blocking plate 46 screwed to the transfer screw 50 rises upwards to be in the hood chamber 22.

In such a state, the person can cook the food in a state where the food is easily accessible.

Since food does not need to be close to the range hood when the food is cooked or cooked further, in this case, if the person falls to some extent from the range hood, the infrared sensor 60 detects it again.

Therefore, this time, the reverse rotation drive signal is transmitted to the transfer motor 40, so that the gas blocking plate 46 screwed to the transfer screw 50 is lowered in the hood chamber 22 to have a state as shown in FIG. do.

As a result, the front of the hood 20 has an effect that the front of the hood is drooped downward by the amount of the gas blocking plate 46, so that all the smoke and odor generated from the food is sucked into the hood chamber 22.

As a result, the efficiency of the hood 20 is increased to further improve the comfort of the room.

As described above, according to the present invention, by installing a gas barrier plate that is automatically adjusted up and down on the front side of the range hood to effectively capture the smoke or odor generated when cooking food in the range of the kitchen to realize the comfort of the kitchen or indoors. Can be.
