2. Description of the Related Art Generally, in a cassette type stove,
GOTOKU is a soup saucer-shaped base member with supporting protrusions fixed to it.In a normal installation state, the supporting protrusions are placed on the hob body in the up and down position facing upwards, but they are bulky when packed. For the purpose of lowering the temperature, it is possible to invert it upside down and place it on the hob body with the support projection facing downward.In such an inverted placement state, gas is ejected from the burner and burned. If this is done, a good combustion state may not be obtained.

In view of the above points, a technique has been proposed for preventing the reverse mounting of the stack. As an example, in Japanese Utility Model Laid-Open No. 1-136811, an interference member is provided on the hob body to prevent a part of the gotok in the inverted state from being placed on the hob body in a flat state. There is disclosed a structure in which an interference member for disabling the rotation operation of the instrument cock knob in the state of being installed or inverted is provided, or an interference member for disabling the setting of the gas cylinder is provided.

[0004]

However, in the above-described structure in which the cassette type stove is prevented from being reversely placed, an interference member as a separate component for interfering with a part of the stove is provided. Since it is attached to the main body of the hob by means of screws and cut-and-raised pieces, there is a problem in that holes for forming screws and cut-and-raised pieces are formed on the outer surface of the hob body to impair the appearance.

Further, in the case where the interference member is of a fixed type, when assembling various other parts to the main body of the stove,
It becomes an obstacle and the assembly work becomes complicated, which is disadvantageous in terms of cost. On the other hand, when packing, etc., the movable member is provided so that the interfering member can be moved to reversely mount it. There is a problem that it is difficult to ensure a reliable reverse mounting prevention function with such a mechanism.

Therefore, in view of this point, the present invention has a simple structure so that the interference member for preventing reversal mounting of the product is not obstructive at the time of assembling, and the screw for fixing the interference member and the cut and raised. It is an object of the present invention to provide a cassette-type cooking stove that does not need to be formed to enhance the appearance, and that does not require a moving operation to ensure a reliable operation.

[0007]

The cassette type hob of the present invention, which has solved the above-mentioned problems, is provided with an interference member which is slidable in the vertical direction by its own weight, and the lower end portion of the interference member is a hob. To a length such that the lower end of the filter body comes out of contact with the bottom surface of the hob body, the interference member moves upward by contacting the placing surface when the hob is in use, and the upper end stops at a predetermined height lower than the upper surface of the hob body. When the Gotoku is placed on the hob body in the normal vertical position with the support protrusion facing upward, the upper end of the interference member does not contact the Gotok and the Gotoku can be placed flat on the hob body. On the other hand, when the gotoku is placed on the hob body in the upside-down position with the support projection facing downward, the gotoku support projection interferes with the upper end portion of the interference member to raise and tilt a part of the gotoku. It is characterized by being in a state.

Further, the lower end of the interference member may be enlarged, and it is preferable that the upper end of the interference member is enlarged. You may arrange | position the said interference member in the leg part of a stove main body, penetrating this.

In the above-described cassette type cooking stove, the interference member moves up and down by its own weight, and when the cooking stove is assembled, the interference member is lowered to facilitate the assembly without interfering with other assembly parts. To be able to do it. Also, when the burner is ignited and used, when placed on a mounting surface such as a table, the lower end of the interference member abuts against the mounting surface and is pushed up, and the upper end position becomes high, and When it is placed upside down, a part of it interferes with the upper end of the interference member and is lifted and becomes an inclined state, notifying the user that it is not in a normal state of placement, and resetting it to a normal state Can be installed flat and prevent reverse mounting.

Further, since it is not necessary to fix the above-mentioned interference member, no screw or cut-and-raised appearance appears in the external appearance, and the assembling work can be facilitated, which is advantageous in terms of cost.

[0011]

According to the cassette type cooking stove of the present invention, in the conventional gotoku reversal placement preventing mechanism, the interference member is fixed to the cooking stove main body in a case other than the time of use such as packing. Also, the anti-reverse placement prevention function of Gokutoku works,
In the present invention, since the interference member is vertically movable by its own weight, it is possible to reversely mount the product by lowering it to a position where it does not interfere during packaging, etc., so that the space is small and it does not get in the way. There is an effect. Further, since the interference member moves by its own weight, it is not necessary to perform a setting and resetting operation for moving the interference member, and when the stove is placed on a table or the like, the interference member moves by contacting the mounting surface,
The normal reversal placement preventing position is moved to the non-interference position by pushing due to its own weight or interference when it is lifted from the table or the like, and a reliable operation can be obtained with a simple structure.

When the lower end portion of the interference member is formed to be enlarged, the lower end portion of the interference member does not fall into the gap or the groove formed on the mounting surface, and the anti-reverse mounting function of the stack can be secured.

Further, in the case where the upper end portion of the interference member is formed to be enlarged, even when the mounting position of the profitable member is slightly displaced when the reversely mounts the profitable member, the sloped mounting of the profitable member due to the interference with the interference member can be performed. , Its preventive function can be secured.
