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]

2. Description of the Related Art In JP-B-46-35878 and JP-B-47-41251, a lid is rotatably attached to a rear portion of a support base as a stand via a hinge, and the lid is rotated. A main body case having an upper surface opening that can be opened and closed by means of a support base is detachably supported from its front side, and a pair of upper and lower heaters, which are separately arranged inside the main body case and the lid, are attached to the hinges. Electric cooker is shown.

The support base of this cooker is formed by bending a wire rod and has a mounting portion, a leg portion in contact with the floor surface, and a rising portion to which a hinge is attached. The bottom of the main body case is in the shape of a basin having a step, and the central portion of the main body case surrounded by the step projects below the step. The main body case is supported over the mounting part 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 support base and pushing it horizontally, and by pulling it forward from this supported state. It can be removed from the support base.

[0004]

However, according to the techniques described in the above publications, since the support base to which the main body case is attached and detached is formed by bending the wire rod, its mechanical strength is low. There is a problem of being small. At the same time, since the support base is composed of the wire rod body, the bottom surface of the case faces the installation surface of the cooker in the state of supporting the case. Therefore, there is a problem that the installation surface is easily heated by the radiant heat from the main body case that is heated by the heater during cooking. To prevent this, it is necessary to increase the height of the legs of the support base. A new problem arises that the vessel becomes larger.

An object of the present invention is to obtain a cooker which can improve the strength of the support base, can prevent heating of the installation surface while being compact, and can easily attach and detach the main body case to and from the support base.

[0006]

In order to achieve the above-mentioned object, the cooking device of the present invention has a box-shaped main body case having an open top surface which is provided at the peripheral portion thereof so as to be freely inserted and removed from the front side. Formed with a dish-shaped heat shield having an upright edge that supports the bottom wall of the main body case, and legs attached to the left and right ends of the heat shield through fasteners, respectively. The upper end of the rising edge is located above the upper end of the fixture.

[0007]

In the cooker having the above-mentioned structure, when the main body case is put in and taken out from the front side of the support base, the main body case is moved with its bottom wall along the rising edge of the heat shield plate of the support base. Therefore, this movement can be guided by the rising edge, and since the upper end of the rising edge is located higher than the upper end of the fixture with legs attached to the heat shield plate, the bottom wall of the main body case to be moved is fixed. Never get caught in. Since the support base places the bottom wall of the main body case on the rising edge of the heat shield plate and supports the main body case, the heat shield plate covers most of the bottom wall of the main body case when the main body case is supported. A space is formed between the dish-shaped heat shield plate and the bottom wall while covering from the lower side. Therefore, when there is no water in the main body case during cooking, most of the heat released downward from the bottom wall of the case can be blocked by the heat shield plate of the support base. Further, since the heat shield plate has a dish shape having an upright edge on the periphery thereof, its mechanical strength is large, and therefore the strength of the entire support base can be improved.

On the contrary, in order to attach the lid 19 to the hinge member 31, the lid 19 is inserted into the through hole 21 of the lid 19 through the heat source 38, and then the wall is applied to the closing plate 37. By this operation, the locking projection 24 is passed through the lid stop hole 43 and inserted into the notch groove 40 of the support member 39 (this state is shown in FIG. 6), and the lid stop pieces 37 are inserted in the left and right engagement holes 22. Insert each. Next, the operation portion 39b on the stop side of the support member 39 is pushed. Then, the supporting member 39 is moved to the right side in the drawing with the upward displacement as shown in FIG. 7 against the spring force of the coil spring 42, and the lid stopper projection 41 thereof is formed.
Moves over the locking groove 23 of the locking projection 24, and the support member 39 is slightly lowered so that the locking projection 24 and the lid stopper projection 41 are engaged with each other as shown in FIG. Then, at the same time when the support member 39 is lowered, the through hole 22 and the blocking plate 35 are formed.
The lid body 19 is engaged with the lid stopper piece 37 of the
It is attached to the hinge member 31 via 9. In addition, also in this case, there is a feeling of movement and sound.

As described above, since the lid 19 can be attached and detached based on the operation of the support member 39 located outside the lid 19, the work such as removing the lid 19 without opening can be simplified. Become. At the same time, the support member 39 is arranged outside the lid body 19, so that the member 39 is prevented from being contaminated with oil or the like produced from the food. Therefore, it is possible to prevent the hands from being soiled when the lid 19 is attached and detached, and the support member 39 prevents the heat source 38 from covering the lid 19.
Since the rear wall and the upper hinge fitting 33 are provided between them, they are not directly heated by the heat source 38 and their thermal damage can be prevented. Therefore, a cooker with a long life can be obtained as described above.

Further, not only can the lid 19 be removed, but the reflector 27 can be easily removed from the lid 19 without using a hand tool, and the main body case 13 can also be removed from the support base A by a hand tool. It can be easily removed without using it, and the grill 18 can also be easily removed from the main body case 13. Therefore, the main body case 13, the grill 18, the lid body 19, and the reflection plate 27 can be individually washed in a single-piece state and washed as a whole. At the same time, the support base A, the heat sources 11 and 38, the blocking plates 10 and 35, and the like are exposed by removing these detachable parts, so that they can be easily cleaned.

Further, when the main body case 13 is taken in and out from the front side of the support base A, the main body case 1
3, the bottom wall 13a is moved along the rising edge 1a of the heat shield plate 1, so that this movement can be guided by the rising edge 1a. Along with this, the upper end of the rising edge 1a is located higher than the upper ends of the screws 3 that attach the legs 2 to the heat shield plate 1 and the screws 5 that connect the lower hinge member 4, so that the main body case 13 to be moved is The bottom wall 13a does not get caught on the screws 3 and 5. Therefore, the main body case 13 can be easily attached to and detached from the support base A.
