Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device such as an electric roaster or a gas roaster.

[0002]

In Japanese Utility Model Publication No. 47-41251, a stand for supporting a container body, an upper and lower hinges rotatably provided at the ends of the stand, an upper lid provided on the upper hinge, and a lower hinge provided on the lower hinge. An electric cooker equipped with a heater, a container body with an elongated hole for allowing the heater to be inserted and removed, and a container lid provided at the base of the heater to cover the elongated hole of the container body when the heater is inserted It is shown.

The stand is formed by bending a wire and has a mounting portion extending in the front-rear direction, a leg portion in contact with the floor surface, and a portion to which a hinge is attached. The bottom of the container body has a basin shape having a step, and the central portion of the container body surrounded by the step projects downward from the step. The container body is supported across the left and right mounting parts by placing the step parts at the left and right sides of the central part of the bottom part on the mounting part of the stand and pushing it horizontally. In this supporting state, the lower heater and the container lid are inserted into the container body through the elongated holes, and the container lid covers the elongated holes from the inside of the container body. Further, the container body can be detached from the stand by pulling it forward from the supported state.

[0004]

However, according to the above-mentioned conventional example, since the container lid covering the elongated hole of the container body is inserted into the elongated hole, the hole edge of the elongated hole and the peripheral edge of the container lid are formed. Between them, a play gap of a considerable size is necessarily formed in order to make it easy to put the container lid in and out of the slot. Therefore, during cooking, the outside air easily flows into the container body through the gap, which causes a problem of poor thermal efficiency. In addition, since the conventional stand does not have a structure that regulates the horizontal position of the container body supported by the stand by the relationship between the elongated hole and the heater passing through the stand, the container body is placed on the mounting portion of the stand. There is a high possibility that the heater will be caught in the elongated hole when it is placed and pushed backward, and the container body must be attached while aiming at the position, which is a troublesome problem. Further, in the above-mentioned conventional example, since the stand does not have a handle, when carrying the electric cooker as a whole, it is necessary to grip the legs contacting the floor surface of the stand, which is inconvenient in handling. There is also a problem. An object of the present invention is to provide a cooker which can improve thermal efficiency, can be easily attached to a main body case into which a heat source is inserted, and can be easily carried.

[0005]

In order to achieve the above-mentioned object, a cooker according to the present invention comprises a main body case having a box-like shape having an opened upper surface and a rear wall having a horizontally long heat source passage portion. A lid that opens and closes an upper surface opening of the main body case, a hinge that rotatably supports the lid, and a closing plate that is attached to the hinge and that overlaps the outer surface of the rear wall to close the heat source passage portion from the outside. A heat source attached to the hinge and disposed in the main body case through the heat source passage portion; and a base provided with the rear portion connected to the hinge and in which the main body case can be freely inserted and removed from the front side,
The base has a handle attached to each of the left and right ends of the base to stop the left and right movements of the body case on the base.

[0006]

In the cooker of the above construction, since the handles are provided on both the left and right sides of the base on which the main body case is placed, the entire cooker can be easily carried by grasping the handles. The main body case is attached to the base by locating the main body case between the left and right handles and pushing the base case from the front side toward the rear side. Then,
The heat source attached to the hinge along with this pushing is inserted into the inside of this case through the heat source passage portion of the main body case, and the closing plate attached to the hinge is attached to the rear of the main body case when the pushing is completed. The heat source passage is closed from the outside by overlapping the outer surface of the wall. Moreover, the handles located on both the left and right sides of the body case by such attachment prevent the body case from moving in the left-right direction. Therefore, in the pushing operation of the main body case, the left and right handles regulate the movement of the main body case in the left-right direction so that the heat source passage portion and the heat source are aligned with each other. Further, as described above, since the heat source passage portion is closed from the outside of the main body case by the closing plate, the gap formed between the heat source passage portion and the closing plate can be reduced. Therefore, it is possible to reduce outside air from flowing into the main body case through the heat source passage during cooking.
