Hereinafter, the configuration of the present invention using the accompanying drawings to be described in more detail.

As shown in FIGS. 1 and 2, an exhaust fan 2 is provided inside the case 1, and an exhaust port 3 is provided above the exhaust fan 2. The gas is sucked from the inlet port 4 and discharged to the outside through the exhaust port 3, and an air supply fan 5 is formed on the front surface of the first air supply port using air moved by the air supply fan 5. The air curtain is formed at (6) to block the pollutants, excess heat and odor, and the air jet function is directed to the exhaust port (3) by the air jet function in the second air inlet 6a of the air jet type. Guiding to is the same as the conventional configuration.

However, the exhaust fan 2 used a BLDC motor (Brushless Motor (BLDC)) with high power consumption, low electrical and mechanical noise, and no wear.

In addition, as shown in FIG. 4, the inlet 4 is provided with an LED lamp 10 made of a crystal LED.

The LED lamp 10 has a power consumption of 1W, the illumination is to install two LED lamps 10 of 49.4 Lux.

Then, the electric damper 20 is formed between the exhaust fan 2 and the exhaust port (3).

The electric damper 20 is electrically connected to interlock with the controller 40, which will be described later. The electric damper 20 acts to open during operation and closes during non-operation so that the polluted air does not flow back to the room during non-operation.

On the other hand, the coating part 30 forms the aluminum anodizing coating part 31 on the outside of the case 1 for protecting the outer side of the 1st, 2nd mechanism 6 and 6a, and to protect the intake port 4, and The ceramic coating 32 is formed on the outside of the case 1 so that oil, water, and gas generated when cooking food are adhered to the case 1, so that the cloth can be sufficiently washed with water. Equipped to.

In addition, the controller 40 adjusts the input voltage as shown in FIG. 3 to adjust the operation step up to four steps, the air volume button 41 and the stop button 42 which can stop the operation and the lighting ON / OFF It is provided with the lighting button 43 which can be made, and the timer button 44 which sets a time so that a power may be turned OFF at a predetermined time.

Here, the air volume button 41 has a different input voltage for each stage. A voltage of 2.0V is applied in one stage, 2.5V in two stages, 3.0V in three stages, and 3.5V in four stages.

In addition, in the operation step of the air volume button 41, the third and fourth stages can set the input voltage by using the dip switch 40a formed inside the controller 40. In 4 stages, it can be adjusted to 3.5V, 4.0V, 4.5V.

In addition, the control unit 40 may further configure a regular ventilation mode 45, wherein the input voltage of the normal ventilation mode 45 is applied at 1.4 V, and the normal ventilation mode 45 is exhausted. It works in conjunction with the fan (2).

Here, the buttons of the control unit 40 are turned on when pressed once and turned off when pressed again, but in the case of the air volume button 41, when pressed once, the second stage is turned on by two stages, and when pressed again, the button is turned off.

Looking at a preferred embodiment of the simultaneous / exhaust type hood of the present invention having the configuration as described above are as follows.

First, as shown in FIG. 2, power (not shown) is applied to the concurrent class / exhaust hood 50 to inhale and discharge contaminants such as oil, water, and gas generated during food cooking to the outside. Then, when the air volume button 41 is pressed, the exhaust fan 2 and the air supply fan 5 made of a BLDC motor operate, and the exhaust fan 2 sucks and pollutes through the intake port 4 to operate. At the same time, it passes through the electric damper 20 to be discharged to the exhaust port 3, and the air sucked from the air supply fan 5 forms an air curtain in the first air supply port 6 to form pollutants, excess heat, and odor. In the second air supply 6a, the pollutants, the excess heat, and the smell are induced in the air supply 6 direction.

In addition, by pressing the illumination button 43 of the control unit 40, two LED lamps 10 made of a crystal LED having a power consumption of 1 W and illuminance of 49.4 Lux are provided in the case 1 in which the intake port 4 is formed. Lights up.

In general, in the case of a three-wavelength lamp, the power consumption is 15W and the illuminance is 52 Lux, while the difference in the illuminance is low and the power consumption is low, so that energy can be emitted while saving energy.

In addition, the exhaust fan 2 made of the BLDC motor, the electrical and mechanical noise is relatively small compared to the general AC motor can be used without the user feel uncomfortable.

Meanwhile, the simultaneous class / exhaust type hood 50 of the present invention uses the control unit 40 formed with the air volume button 41 to change the operation step by varying the input voltage according to the use purpose and the installation environment. Can be used according to the purpose.

FIG. 5 is a diagram illustrating the relationship between the positive pressure and the air flow rate according to the driving stage, and as shown in the drawing, the driving stage may be adjusted in consideration of the static pressure of the indoor environment according to the voltage, that is, the driving stage. Since the input voltage can be set differently using the dip switch 40a formed inside the control unit 40, it can be used in different environments such as high-rise or low-rise houses.

For example, as shown in FIG. 6, the dip switch 40a may adjust the voltage by using a combination of 0 and 1 to adjust the voltage. However, in the present invention, two dip switches 40a may be used. In the fourth stage, only three cases are used to adjust the input voltage value according to each case.

Referring to FIG. 5, it can be seen that all the driving stages determine the blowing amount in inverse proportion to the change in the static pressure. By using this, it is possible to adjust the blowing amount in a wide range according to various indoor environments.

In general, when the air volume increases, the noise is proportionally increased due to the friction of the air. Therefore, in consideration of this, the air volume may be increased in a place where the user does not have to worry about the noise. In this case, it is possible to meet the needs of the user by lowering the air flow as much as possible, that is, lowering the operation level.

In addition, even though air curtains are formed among the contaminants generated during food cooking, some of the contaminants scattered to the inside are adhered to the outside of the case 1 and adhered over time. At this time, a coating formed on the outside of the case 1 is applied. Since the contaminants remain unattached by the part 30, even after wiping with a cloth soaked with water after cooking the food, the contaminants can be removed from the case 1, thereby keeping the clean state at all times.

When water comes into contact with the aluminum anodizing coating 31 and the surface to which foreign matter is attached, the ceramic coating part coated with the eClean ceramic coating technology, which combines OH and H2O, pushes out contaminants on the surface and floats them on the water. This is because when the contaminants adhere to the case 1 by (32), foreign matters are easier to remove than the general coating.

On the other hand, when food cooking is completed and the operation is stopped, some contaminated air not discharged to the exhaust port 3 toward the intake port 4 due to the air pressure difference between the air in the exhaust port 3 and the intake port 4. At this time, the electric damper 20 which is interlocked with the controller 40 is operated at the same time as the end of the operation, thereby blocking the contaminants flowing back.

Here, the electric damper 20 has a leakage amount of about 2.8CMH when the static pressure of the general home is assumed to be 12 mmAq, as shown in FIG. 7.

This is approximately 0.0008 m / s in terms of speed, which is very small compared to the total air flow.

In addition, according to the recently announced government's indoor air quality management law (managed by the Ministry of Environment) for multi-use facilities, apartments that have been approved for business since January 2006 can provide natural ventilation or machinery that can provide 0.7 or more ventilations on a 24-hour basis. Ventilation equipment must be installed, the simultaneous class / exhaust hood 50 of the present invention is further provided with a constant ventilation mode 42 in the control unit 40 to be able to ventilate the room without a separate natural ventilation or mechanical ventilation equipment have.

In this case, the input voltage during the operation of the ventilation mode 45 is 1.4V. Referring to FIG. 6, it is possible to ventilate using the exhaust fan 2 to a value over 200CMH.

This is a condition that can be sufficiently ventilated indoors only by the air flow amount of 200CMH because the main cause of indoor air is contaminated by the cooking of food in the kitchen in the case of the apartment house.

Although the above-described embodiments have been described with respect to the most preferred embodiments of the present invention, it is not limited to the above embodiments, and various modifications are possible within the scope without departing from the technical spirit of the present invention. It is evident to those who have knowledge of.

As described above, in the simultaneous / exhaust type hood of the present invention, since the exhaust fan is composed of a BLDC motor, the electrical and mechanical noise is low and power consumption is low, so that the cost reduction effect can be achieved. Even when ventilating, the cost can be saved by BLDC motor with low power consumption.

In addition, the LED lamp with low power consumption can be used to reduce the cost of using the lamp, and can effectively block the flow of air backflowed by the electric damper formed between the exhaust port and the exhaust fan. It opens automatically when driving and can block backflow air when not driving.

And, by the coating portion formed on the outside of the case, foreign matters such as excess heat or oil generated during cooking can be easily cleaned using a cloth soaked in water and easy to maintain.

In addition, it is possible to adjust the input voltage of the third and fourth stages even when the indoor environment is installed elsewhere, it is a useful invention that can not only smooth the normal supply / exhaust, but also reduce the noise.
