-In above-mentioned embodiment, although the compound cooker was made into the gas range, in the oven 100 and the stove 200, the heat source (fuel) for heating a to-be-cooked object is not restricted to gas. For example, the composite cooker may use electric power as a heat source. And when using electric power as a heat source of the stove 200, it can replace with the burner 201, for example, can provide the IH heater which heats a pan etc. by induction heating, the sheathed heater which heats by resistance heating, etc. Moreover, when using electric power as a heat source of the oven 100, for example, a heater is provided as the heat generating unit 102, and heat for cooking is generated by the heater. When the heat generating unit 102 generates heat without combustion, all of the gas generated in the heat generating unit 102 may be circulated between the heating chamber 101 and the heat generating unit 102. According to this configuration, it is possible to reduce the exhaust heat due to the discharge of the gas generated in the heat generating unit 102 and perform cooking efficiently.

  The bottom plate portion 117 may not include the latching portion 120, and the opening / closing lid 115, the bottom plate portion 117, and the oven plate 118 may be integrated. According to this configuration, along with the sliding movement of the opening / closing lid 115, the oven pan 118 can be moved in a more stable state. In addition to the opening / closing lid 115, the bottom plate portion 117, and the oven plate 118, a support unit that can support the oven plate 118 (for example, the bottom portion 104 that does not include the vent hole 105 and the exhaust port 106) can be integrally slidably moved. It may be. According to such a configuration, the inclination of the oven pan 118 that moves together with the opening / closing lid 115 can be suppressed. Alternatively, the open / close lid 115, the bottom plate portion 117, and the support portion that can support the oven tray 118 may be configured to be slidable together, and the oven tray 118 may be configured separately.

  The upper wall part 110 and the side wall parts 111, 112, 113, 115 of the heating chamber 101 may not include the transparent part 130. However, when the wall portion of the heating chamber 101 has the transparent portion 130, the larger the area of the transparent portion 130, the easier it is to visually recognize the inside of the heating chamber 101, and the more the wall portion having the transparent portion 130, the heating chamber 101. It is preferable because the inside can be viewed from multiple sides. In addition, in order to visually recognize the inside of the heating chamber 101 in a multifaceted manner, it is preferable that there are two or more wall portions having the transparent portion 130. Moreover, in order to visually recognize the inside of the heating chamber 101 without bending, it is preferable that at least the upper wall portion 110 has the transparent portion 130. Therefore, in the heating chamber 101, the upper wall portion 110 and the side wall portions 111, 112, 113, and 115 may not all be the transparent portion 130, but the upper wall portion 110 and at least one side wall portion have the transparent portion 130. It is preferable. In this case, the entire wall portion does not have to be the transparent portion 130, and it is sufficient that the transparent portion 130 is formed at least partially.

The wall portion 110 may be integrated so that the integrated portion functions as an opening / closing portion. For example, when the upper wall portion 110 and the side wall portions 112 and 113 are integrally formed to be an opening / closing portion, if a rotation shaft is provided at the lower end portion of the side wall portion 112, the opening / closing portion is rotated. The oven pan 118 placed on the heating chamber 101 can be exposed.

  Further, the rear portion of the upper wall portion 110 and the rear wall portion 111 are integrated to form a first opening / closing portion, while the front portion of the upper wall portion 110 and the front wall portion 115 are integrated to form a second opening / closing portion. It can also be an opening / closing part. In this case, the two opening / closing parts can be opened on both the rear side and the front side.

  According to these configurations, the cooking object can be taken in and out of the heating chamber 101 without moving the oven pan 118 through the opening that opens when the opening and closing portion is opened. The length can be shortened. Moreover, according to this structure, since the opening / closing part can be opened / closed not only from the front of the top plate 15 but also from the back or side, particularly when the composite cooker 11 is made into an island type or a counter type, Usability can be improved. Further, according to this configuration, at least a part of the inner wall of the heating chamber 101 can be exposed to the outside by opening the opening / closing part, so that the heating chamber 101 can be easily cleaned.
