Meanwhile, the actuator 51 may overheat during operation. In this embodiment, the circulation module 50 may perform the function of self-cooling the overheated actuator 51. For this purpose, the rotating shaft member 52 may be provided with a cooling fan 54.

At this time, the cooling fan 54 may be disposed adjacent to the actuator 51 on the outside of the internal frame 10. Accordingly, the driving force generated from the actuator 51 rotates not only the circulation fan 53 but also the cooling fan 54, thereby generating air flow around the actuator 51. Accordingly, the circulation module 50 according to this embodiment can cool the actuator 51 by itself.

Meanwhile, although not shown in the drawing, a separate power transmission member such as a gear may be additionally provided between the actuator 51 and the rotating shaft member 52.

Referring again to FIGS. 2 to 4, a duct frame 60 may be provided between the actuator 51 and the internal frame 10. In the illustrated embodiment, the duct frame 60 is provided on the outer portion of the upper plate 16 of the inner frame 10.

At this time, a plurality of intake holes 65a may be provided. The plurality of intake holes 65a may be spaced apart from each other around the actuator 51 as shown in FIG. 3 .

When the cooling fan 53 inside the intake unit 65 rotates, external air is sucked into the intake unit 65 through the intake hole 65a. The external air sucked in during the above process passes around the actuator 51 and can cool the actuator 51. Of course, the air flow direction may be reversed. More specifically, the air inside the intake unit 65 is discharged to the outside of the intake unit 65 through the intake hole 65a by the cooling fan 53, so that the discharged air cools the actuator 51. It may be configured.

Meanwhile, referring to FIGS. 3 and 4 , a discharge portion 66 may be provided on one side of the intake portion 65, for example, in the front portion with respect to FIG. 3 .

In addition, even if the first heating object A1 in the internal cooking space S1 is made of a material that is not heated by induction heating, the heating ability of the moving heat source 140 is sufficiently used to heat the first heating object A1. can be heated.

In this way, the cooking appliance 101 according to the second embodiment of the present invention heats the first heating object (A1) in the internal cooking space (S1) together with the internal heat source 122 and the moving heat source 140, thereby enabling more rapid heating. Cooking can be performed.

Referring to FIG. 16, the moving frame 130 and the moving heat source 140 may be spaced apart from the coupling plate 102b of the housing 102 so that an object can be placed on one side of the moving frame 130. . In other words, the moving frame 130 and the moving heat source 140 may be disposed adjacent to the external cooking space (S2) provided outside the housing 102. Hereinafter, this position is referred to as the second position. The second location may be located further away from the internal cooking space S1 than the first location.

Even if the moving frame 130 and the moving heat source 140 are located in the second position, the internal heat source 122 heats the surrounding air and the circulation fan 157 heats the heated air around the internal heat source 122 in the first position. By circulating toward the object A1, the first heating object A1 can be heated.

The mobile heat source 140 located at the second position may heat the second heating object A2 in the external cooking space S2. The second heating object A2 may be, for example, a cooking utensil such as a pot containing food to be cooked. At this time, the second heating object A2 may be supported by the moving frame 130.

In this way, in the cooking appliance 101 according to the second embodiment of the present invention, the internal heat source 122 heats the first heating object A1 in the internal cooking space S1, and the mobile heat source located at the second position By heating the second heating object A2 in the external cooking space S2 (140), a plurality of cooking operations can be performed simultaneously.

As described above, in the cooking appliance according to an embodiment of the present invention, an internal heat source heats a first heating object disposed in the internal cooking space, and a moving heat source located at the first position heats a predetermined heating object disposed inside the housing. By heating, rapid cooking can be performed.

In addition, in the cooking appliance according to an embodiment of the present invention, an internal heat source heats a first heating object disposed in the internal cooking space, and a moving heat source located at a second position heats a second heating object disposed in the external cooking space. By doing so, multiple cooking operations can be performed simultaneously.

Furthermore, the cooking appliance according to an embodiment of the present invention is configured so that a movable heat source can move between the first position and the second position, so it has the function of quickly cooking one cooking object and a plurality of cooking objects simultaneously. Since it provides the ability to cook while minimizing the space it occupies, the usability of surrounding space can be increased and the overall weight of the cooking appliance can be reduced.

At this time, the cooking appliance according to an embodiment of the present invention can efficiently heat the first heating object or cool the actuator of the circulation module by circulating the air inside the housing using the circulation module.
