In addition, it is preferable that the lighting unit emits light of different colors according to the operating state of the hood. For example, light of a first color may be output when the head is moved, and light of a second color may be output when gas is sucked. In addition, it is also possible for the lighting unit to output light having a different color according to the determined number of heat sources.

8 is a flowchart of a method of operating a cooking appliance system according to an embodiment of the present invention.

Referring to FIG. 8 , in the cooking appliance system according to an embodiment of the present invention, when one or more heat sources of a cooktop, for example, an induction heating cooking appliance are turned on (S810), the hood also cleans the air The function can be ready.

The cooking appliance system according to an embodiment of the present invention may determine which heat sources are turned on and the number thereof (S820).

When there is only one turned on heat source (S820), a head of a hood may be moved over the one turned on heat source (S830), and when there are a plurality of turned on heat sources (S820), the plurality of turned on heat sources The head may be moved to an intermediate position (S835).

The cooking appliance system according to an embodiment of the present invention may detect gas through a gas sensor after the head is moved (S830 and S835) (S840).

The hood and cooking appliance system according to an embodiment of the present invention may detect a heat source through a heat sensor or move the head 1110 to a position of the heat source when the cooking appliance heat source is turned on. have.

The hood and cooking appliance system according to an embodiment of the present invention may perform different corresponding operations according to the determined number of heat sources.

When there is one determined heat source, as shown in FIG. 11 , the head 1110 including the intake port may be moved over the determined one heat source.

Also, when there are a plurality of the determined heat sources, the head 1210 may be moved to an intermediate position of the determined plurality of heat sources 1201 and 1202 as shown in FIG. 12A .

According to the present invention, upon detection of a heat source, the hood, at least the head, can be moved to an optimal position.

In addition, the hood and cooking appliance system according to an embodiment of the present invention may detect gas through a gas sensor after the head is moved. When the gas is sensed, the gas may be inhaled.

When the determined heat source is one, gas intake can be started at the current position without moving the head.

In addition, when there are a plurality of the determined heat sources, as shown in FIG. 12B , the head 1210 may reciprocate between the plurality of determined heat sources 1201 and 1202 to suck gas.

That is, the head 1210 may suck gas while sequentially moving over the currently operating heat sources 1201 and 1202 .

That is, according to an embodiment of the present invention, it is possible to perform gas suction and air cleaning functions in different positions and operations according to the number of the determined heat sources.

Referring to FIG. 13 , the hood according to an embodiment of the present invention may include a lighting unit 1312 for outputting light. Preferably, the lighting unit 1312 includes the lighting unit 1312 , the intake port 1311 . can be placed around

The lighting unit 1312 may include one or more light sources and may output one or more color lights.

Gas inhalation can be visualized through the lighting of the lighting unit 1312, and harmful vapors and inhalation performance can be visualized.

In addition, it is possible to maximize the visual effect of the cooking situation.

In addition, it is preferable that the lighting unit 1312 irradiate light of different colors according to the operating state of the hood.

14 is a side view showing the air flow of the hood employing a preferred embodiment according to the present invention is shown.

Referring to FIG. 14 , when a user drives the hood according to an embodiment of the present invention while cooking food using the cooking device 10 , the gas 70 is formed between the cooking device 10 and the upper structure ( 30) do not stray from the in-between.

Referring to Figure 14, the top line (Top Line) means the height to the average nose of a 20 to 50-year-old female adult adult, for example, the bottom line means the height from the height of 1430mm to the nose of a 2-year-old to 4-year-old child (Bottom Line), for example, it is possible to remove harmful gases between the height of 880mm.

According to at least one of the embodiments of the present invention, it is possible to provide a hood and a cooking appliance system capable of effectively removing harmful gases generated during cooking.

In addition, according to at least one of the embodiments of the present invention, there is an advantage that harmful gas can be inhaled and blocked at an optimal position.

In addition, according to at least one of the embodiments of the present invention, it is possible to intuitively grasp the operating state.

In addition, according to at least one of the embodiments of the present invention, it is possible to provide a hood and a cooking appliance system with improved user convenience.

On the other hand, although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the technical field to which the present invention belongs without departing from the gist of the present invention as claimed in the claims In addition, various modifications may be made by those of ordinary skill in the art, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.

Cooking equipment: 100
Hood: 200
Head: 210
Intake: 211
