As shown in Figures 1 to 3, the cooking device is a hood-integrated cooktop in which an exhaust device, which is a hood that exhausts air containing contaminants generated in the process of cooking food to the outside, is coupled to the lower part of the cooktop 10. It can be. In the drawing, the cooktop 10 is shown as an induction electric cooktop, but it is not limited thereto. In other words, there may be no limitation on the type of cooktop 10. For example, the cooktop 10 may be a highlight among electric cooktops. In the case of induction, the top plate 20 is not heated by using a magnetic field to allow current to flow, and the cooking vessel 1 is directly heated, so the top plate 20 is not hot, which can reduce the risk of burns. However, only metal containers that attach magnets can be used as the cooking container (1), and glass, ceramics, or aluminum cannot be used. In the case of highlighting, electricity flows through the nichrome wire under the ceramic plate and heats the top plate and cooking vessel with that heat, so the top plate becomes hot, so there may be a risk of burns.

The communication hole 40 may be formed at a location corresponding to the heat sink 13. This means that when the external air sucked into the plurality of suction holes 36 by the hood fan 70 is discharged to the exhaust duct 60 through the communication hole 40, the heat sink ( 13) This may be mainly for cooling. That is, since more heat is generated in the heat sink 13 than in the plurality of electrical components 11, the communication hole 40 is formed at a position corresponding to the heat sink 13 and is discharged through the communication hole 40. The air discharged into the duct 60 can pass through the upper part of the heat sink 13. Since two heat sinks 13 are provided inside the cooktop 10, two communication holes 40 can also be provided to correspond to the number of heat sinks 13. However, it is not limited to this. That is, although the drawing shows that two communication holes 40 are formed to correspond to the two heat sinks 13 in order to efficiently cool the two heat sinks 13, the number of communication holes 40 is It is not necessary to correspond to the number of heat sinks 13.

The suction duct 50 has a first flow path (P1) through which air containing contaminants generated in the process of cooking food is sucked into the suction port 21 by the hood fan 70 and delivered to the discharge duct 60. can be formed. Since the inside of the cooktop 10, where the plurality of electrical components 11 and the heat sink 13 are disposed, is separated by the extension duct 51, the first flow path P1 can be separated from the inside of the cooktop 10. . (See Figures 4 and 5)

The discharge duct 60 may be provided in the lower part of the lower plate 30. The discharge duct 60 may include a hood fan installation portion 61 where the hood fan 70 is installed.

The hood fan 70 may be installed in the hood fan installation portion 61 of the discharge duct 60. When contaminants are generated during the process of cooking food, the hood fan 70 may be operated to suck air containing the contaminants into the intake port 21. Since the hood fan 70 has high air volume and fixed pressure characteristics and has a low operating RPM, noise generated when the fan is driven can be reduced.

You can. The air discharged through the discharge duct 60 may be discharged to the outside of the cooking appliance through the discharge port 63.

As described above, the first flow path (P1) and the second flow path (P2) may form independent flow paths. Accordingly, the air moving along the first flow path (P1) and the air moving along the second flow path (P2) may be combined in the discharge duct 60 and discharged through the discharge port 63.

The first flow path (P1) and the second flow path (P2) form independent flow paths, and the first flow path (P1) through which air containing contaminants moves is connected to the inside of the cooktop 10 by the extension duct 51. Because they are separated, contaminants can be prevented from entering the cooktop 10.

As described above, since there is no need to install a separate cooling fan to cool the plurality of electrical components 11 and the heat sink 13 disposed inside the cooktop 10, design constraints can be reduced and manufacturing costs can be reduced. . In addition, the hood fan 70 has high air volume and fixed pressure characteristics and a low operating RPM compared to a separate cooling fan for cooling the plurality of electrical components 11 and the heat sink 13 disposed inside the cooktop 10. Since the inside of the cooktop 10 is cooled, cooling performance can be improved and noise generated when the fan is driven can be reduced.

As described above, a plurality of first suction holes 37 are formed only in the portion corresponding to the heat sink 13 rather than the entire first side wall 32, and a plurality of third suction holes 39 are additionally formed. Cooling performance can be improved by focusing on cooling the heat sink 13, which generates more heat than the plurality of electrical components 11.

Figure 12 is a diagram showing a cooling fan provided inside a cooktop according to an embodiment.

As shown in FIG. 12, a cooling fan 90 may be provided on the opposite side of the communication hole 40 from the heat sink 13. The cooling fan 90 can improve the efficiency with which external air sucked through the plurality of suction holes 36 cools the heat sink 13. That is, the air outside the cooking appliance is sucked into the plurality of suction holes 36 only by the hood fan 70, cools the heat sink 13, and is then discharged into the discharge duct 60 through the communication hole 40. If the cooling fan 90 is added, the efficiency of cooling the heat sink 13 can be improved. (see Figure 6)

In the above description of the cooking appliance with reference to the attached drawings, the specific shape and direction are mainly explained, but various modifications and changes are possible by those skilled in the art, and such modifications and changes are included in the scope of rights of the disclosed invention. It should be interpreted as
