The present invention relates to a blocking plate opening and closing device of the hood for kitchen, in particular, when the blocking plate installed under the hood cover of the hood is standing vertically or inclined when the hood is in operation, heat and contaminated air generated in the oven range is diffused into the room. And a blocking plate opening and closing device for a kitchen hood to prevent backflow of external contaminated air and cold air by covering the lower filter part when the hood is not in operation.

In general, the range hood installed in the kitchen is for discharging pollutants such as smoke, odor, oil vapor, etc. generated during cooking of food to the outside.

The range hood is installed at a predetermined height in the upper part of the oven range, and the gas generated when cooking food rises upwards and gradually spreads to the surroundings, and the gas is leaked toward the front user by riding the wall to the rear to the rear. Contaminates.

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.

1 and 2 is a longitudinal cross-sectional view showing the configuration and operation of a conventional kitchen movable hood device, as shown in the range hood for discharging the gas generated when cooking food in the kitchen, A hood (20) having a hood (22) and a discharge opening (24) in communication with the hood chamber (22), which is enlarged downwardly; 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; The gas blocking plate 46 is screwed to the transfer screw 50 and moves upward and downward from the front surface of the hood chamber 22 according to the rotation direction of the output end of the transfer motor 40.

In addition, a motor bracket 44 is mounted on the front upper portion of the hood 20, and the motor bracket 44 is fixedly installed with a transfer motor 40 which 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, and 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. The gas barrier plate 46, which moves up and down from the inclined front surface of the hood chamber 22, is connected by screwing in accordance with the output end rotational direction thereof.

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 to control the rotation of the transfer motor 40.

In the conventional kitchen movable hood device as shown in FIG. 1, when a person approaches the range hood 10 side, the infrared sensor 60 detects this, whereby the transfer motor 40 is driven and transported. When the screw 50 is rotated forward, the gas blocking plate 46 screwed to the transfer screw 50 rises upward to be positioned 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.
