Description

Electric grill with pollution control function {ELECTRIC GRILL CAPABLE OF CONTROLLING CONTAMINATION}

The present invention relates to an electric grill, and more specifically, to an electric grill that has an efficient smoke blocking and reduction effect by displaying the degree of pollution of inhaled smoke and controlling the inhalation operation of the electric grill accordingly.

An electric grill is a device that heats a grill pan with a heater to grill and cook meat, fish, shellfish, etc. on the grill pan. When cooking using an electric grill indoors, a considerable amount of odor and smoke are generated, and a large amount of fine dust, including oil vapor, is emitted.

Various types of electric grills have been developed to reduce the emission of smoke and fine dust, and recently, electric grills that suck smoke into the bottom of the grill pan and discharge purified air have been developed.

This electric grill is comprised of a fan provided inside a case of a certain size, a motor that rotates the fan according to the supply of power, and a switch to supply/cut off power to the motor. The user operates the switch as needed to supply power to the motor, which drives the fan to suck in the air on the grill, circulate it, and then discharge it.

Such a conventional electric grill requires the user to determine the level of pollution or the amount of smoke in the indoor air and operate it by directly operating the switch. This is not only cumbersome, but it is also difficult to accurately determine the level of pollution in the indoor air with the naked eye or sense of smell alone. There was a problem in that fans were not operated at an appropriate level even when pollution levels were rising, ultimately leaving behind or emitting polluted air.

Referring to FIG. 6, depending on the state of the pollution level, if the pollution level is in a clean state, the control unit 800 may display the phrase “fresh and clean” along with the color green on the display 900. If the pollution level is normal, the display 900 may display the phrase “slight moderate pollution” in orange color, and if the pollution level is above the standard value, the text “severe pollution” may be displayed in red color. At this time, the color, text, each level, and the type of stage can be changed and selected in various ways.

Figure 7 is a diagram showing the control operation of an electric grill according to the present invention. Referring to FIG. 7, the control unit 800 checks whether the electric grill 10 is in automatic mode or manual mode (S1), and in the case of manual mode, determines whether the electric fan 600 operates or suctions according to the user's operation. The intensity is determined, and in the case of automatic mode, operation or suction intensity is determined according to the measured value of the pollution level sensor 700.

The pollution level sensor 700 measures the pollution level of the inhaled air and sends the measured value to the control unit 800 (S2). The control unit 800 receives the pollution level of the air from the detection sensor 700 and determines the operation of the electric fan 600 according to the pollution level.

If the pollution level is in a clean state, the control unit 800 maintains the existing operating state of the electric fan 600 (S3). When the pollution level is in a clean state, the electric fan 600 maintains the current rotation speed, reduces it, or rotates at a set basic rotation speed.

If the pollution level is in the general pollution state, the control unit 800 increases the rotation speed of the electric fan 600 (S4). When the pollution level is in a normal pollution state, the amount of polluted air inhaled per unit time increases, making rapid purification possible.

If the contamination level is severe, the control unit 800 rotates the electric fan 600 at maximum speed (S5). When the level of pollution is severely polluted, more contaminated air can be inhaled and purified, allowing for more rapid purification.

In the above, the degree of contamination was divided into three states, and the rotation speed of the electric fan 600 was determined according to each state, but this is only an example and can be changed depending on the performance or capacity of the electric grill 10. do.
