Description

How to open / close the hood hood

The present invention relates to a method for opening and closing a range of intake hoods, and in particular, allowing the front surface of the intake port of the range hood to be half or fully open, and using the range burner formed on the front side according to the use of the range burner of the gas oven to open the inlet half. The use of the hood hood inlet opening and closing method to increase the suction power by the hood fan that rotates at a constant rotational speed by fully opening the inlet front during use.

In general, when the gas appliance is used, it is possible to prevent the indoor pollution caused by the smell of food by installing a range hood to suck the heat and odor generated during cooking of food and discharge it to the outside.

4 is a perspective view of a conventional stove hood, the stove hood 20 is provided at a predetermined distance from the upper portion of the gas oven 10, the operation portion 22 is provided on the front of the stove hood (20) It is installed, the filter 24 for filtering steam and oil, etc. is attached to the inside, the hood fan 26 linked with the motor is mounted to the upper portion of the filter 24, by the hood fan 26 It consists of an exhaust pipe 28 which discharges the inhaled heat to the outside.

The stove hood configured as described above puts a bowl containing food on the stove burner 11 installed on the gas oven 10 when the user wants to cook in the gas oven 10, and the gas oven The operation switch installed in the operation unit of the stove 10 is turned on to ignite the burner to start cooking food.

In addition, when cooking food in the range burner 11, the switch for driving the motor on the operation unit 22 of the range hood 20 is installed at a certain distance to the upper portion of the gas oven (10). In order to drive the motor, the exhaust pipe 28 is used to control the heat and steam generated when cooking food in the range burner 11 by the rotation of the hood fan 26 interlocked with the motor, and the odor generated from the food. Through the outside.

However, even if the stove hood as described above uses two holes on the front of the stove burner 11 of the gas oven, the heat and food odor are sucked through the suction part 21 by the rotation of the hood fan 26. Therefore, there is a problem in that the suction force is lowered by being distributed and suctioned along the area of the suction part 21 where the hot air and food smell that are sucked are wide.

The present invention is to solve the above problems, the front half of the inlet of the hood hood to be fully open or in accordance with the use of the stove burner of the gas oven when using the range of the burner in the front half of the inlet of the range hood It keeps inhaling heat and food odor through a small area, and in the whole use of the range burner, it opens the front of the intake port so that it can be inhaled to increase the suction power by the hood fan rotating at a certain speed. It is an object of the present invention to provide a method for opening and closing a suction port.

According to the present invention for achieving the above object, the user turns on the stove burner switch of the gas oven for cooking, and then turns on the range hood switch to discharge the heat and food odor generated during cooking to the outside. A first step of determining whether the entire burner is ignited, a second step of maintaining the current half opening of the inhaler if the entire burner is not ignited in the first step, and the entire range of burner in the first step When the ignition is ignited, the control unit rotates the motor forward and thus the barrier film is folded along the guide surface to open the suction part of the range hood to inhale heat, and then the control unit determines whether the range burner has been extinguished. If the burner was extinguished in step 3, the control unit rotates the motor in reverse to move the barrier to one side of the center of the range hood. Moves along the guide surface which extends characterized in that it includes a fourth step for returning to the original position the protection film.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a block diagram schematically showing the configuration of the stove hood according to the present invention, the stove burner switch 30 for turning on or off the stove burner 11 and the stove hood 20 for sucking food smell or heat on Or the range hood switch 32 which is turned off is connected to the control part 34, respectively.

In addition, the motor 36 capable of forward / reverse rotation and the blocking film 38 that is opened and closed by driving of the motor 36 are configured to be controlled by the controller 34.

FIG. 2 is a view illustrating a stove hood according to the present invention, in which an operation unit 22 is installed on the front surface of the stove hood 20, and a filter fan 24 for filtering steam and oil, and a hood fan interlocked with a motor. (26) is mounted, and is composed of an exhaust pipe (28) for discharging the heat sucked by the hood fan (26) to the outside.

In addition, the top of the hood fan 26 is installed, the drive shaft 40 is formed across both rear ends of the hood hood 20, the motor 36 is mounted to one side of the drive shaft 40, The other side is rotatably inserted at the end, the guide surface 42 is extended to the center one side along both sides of the range hood 20, the blocking film 38 moving along the guide surface 42 is the drive shaft 40 It is configured to connect with.

Therefore, when the user uses the range burner 11, the range burner 11 is generally used at about 1 or 2 holes on the front, and the suction part 21 of the range hood 20 is kept half open. When the range burner 11 is fully ignited, the drive shaft 40 interlocked with the motor 36 rotates while the motor 36 is rotated forward under the control of the controller 34. As a result, the blocking film 38 covering the suction part 21 is wound to completely open the suction part 21.

On the other hand, when the burner 11 that has been ignited as a whole is extinguished, the motor 36 starts to rotate in reverse. As a result, the driving shaft 40 is also rotated in reverse to move the blocking film 38 along the guide surface 42. The suction part 21 is half closed.

The range hood of the present invention as described above will be described in detail with reference to the flowchart of FIG. 3.

The user turns on the range burner switch 30 installed in the operation part of the gas oven 10 to ignite the range burner 11 to start cooking food (101), and then heat and food smell generated during cooking. When the range hood switch 32 is turned on in order to discharge it to the outside (102), the control unit 34 determines whether the entire range of the burner 11 is ignited or the range burner 11 in accordance with the ON signal of the range burner switch 30. ) Only to determine whether the ignition (103),

Therefore, if only the burner 11 of the front is ignited, the control unit 34 sucks food smell and heat through the intake port 21 of the range hood 20, which is currently half open, and the burner 11 ) If the whole is ignited and cooking food, the control unit 34 controls the motor 36 to rotate forward (105), and the driving shaft 40 rotates forward according to the driving of the motor 36, and the blocking film 38 The suction unit 21 is completely opened by winding (106).

On the other hand, the control unit 34 determines whether the off signal is applied from the range burner 11 after fully opening the suction unit 21 (107), when the off signal according to the digestion of the range burner 11 is applied The controller 34 reversely rotates the motor 36 (108). Accordingly, the driving shaft 40 driven by the driving of the motor 36 is reversely rotated to move the blocking film 38 along the guide surface 42. The suction part 21 is returned to its original half open position (109).

As described above, according to the present invention, when using the range burner of the gas oven, the front half of the stove burner is kept in the open state of the intake port of the hood by inhaling heat and food odor through a small area, In the whole use, the suction port can be opened and the suction can be increased to increase the suction force by the hood fan.
