[Conventional technology]

In conventional cooking appliances, for example, the lid body connected to the main body case via a hinge member and configured to open and close the top opening of the main body case is detachable from the hinge member.
No. 46-35878 is known.

In this device, both ends of a crank-shaped clamp made of a resilient wire such as a wire are rotatably attached to a hinge member to which an electric heater is attached, which is disposed inside the lid. By the toggle action of this clamp, the rear wall surface of the lid body positioned on the clamp mounting surface of the hinge member is connected to the clamp located on the inside of this rear wall surface and the clamp mounting surface located on the outside. It is designed to be removably sandwiched between the two.

In this conventional cooking appliance, the lid can be attached to and removed from the hinge member by manually rotating the clamp, and therefore the lid can be washed separately with water.

[Problem that the invention attempts to solve]

However, according to this conventional technology, since the clamp is placed inside the lid, the clamp is directly exposed to the heat from the electric heater when the cooker is used, resulting in deterioration of the spring properties. May cause damage. In addition, the clamp is likely to be soiled by oil or the like from the food being cooked. When operating this dirty clamp, it is inconvenient to first open the lid and then rotate the clamp inside the lid.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a box-shaped main body case with an open top surface, a box-shaped main body case with an open bottom surface, and a heat source passage part on the rear wall. A lid body that opens and closes the opening, a lower hinge member located outside and connected to the rear of the main body case, and an upper hinge member rotatably connected to the upper part of this member via a hinge shaft. a hinge rotatably connecting the lid body and the main body case; and a heat source attached to the upper hinge and disposed inside the lid body through the heat source passage part, the lid body is detachably attached to the upper hinge member, and a locking protrusion having a locking groove and protruding rearward on the rear wall of the lid body is provided, and the locking protrusion is inserted and removed. A cover fixing hole is formed in the front surface of the upper hinge member, and a support member for attachment/detachment having a release side operation part at one end and a stop side operation part at the other end is connected to each operation part of the upper hinge member. The support member has a cutout groove facing the cover fixing hole and slopes facing opposite to each other in the middle part of the support member. About 3

A spring is attached to bias the support member to a position where the opening of the notch groove always faces the cover fixing hole.

[Effect]

In order to attach the lid to the upper hinge member of the cooker of the present invention, first place the lid so that the heat source passage passes through the heat source, and then attach the rear wall of the lid to the upper hinge member. Insert the locking protrusion of the lid body into the lid locking hole of the upper hinge member so as to overlap. Next, by pushing the stop-side operation part of the support member for attachment/detachment operation and moving the support member against the elastic force of the spring, the lid stop protrusion of this member is brought into engagement with the above-mentioned lock protrusion. Pass it through the stop groove and get over it. Immediately thereafter, the support member is pulled back by the elastic force of the spring, and at the same time, the lid stopper projection and the locking groove of the locking protrusion are engaged with each other. Thereby, the lid body is attached to the upper hinge member so that it will not come off in the forward direction.

To remove the lid from the upper hinge member, the removal operation portion of the support member is pushed and the member is moved, thereby removing the lid retaining protrusion from the retaining groove of the retaining protrusion. At the same time, the restraint of the lid body is released, the open part of the notch groove of the support member is opposed to the lid stopper hole, and the locking protrusion is disposed in the open part. Therefore, after this, the lid can be removed by pulling it forward.

The upper and lower hinge members that make up the above-mentioned hinge are both located outside the main case and the lid, and since the upper hinge member is provided with a support member for attaching and detaching the lid, the support member is ultimately attached to the main case and the lid. It is placed outside the lid. Therefore, the support member for attaching and detaching operations is prevented from being directly exposed to heat from the heat source, oil from cooking food, etc.
Therefore, thermal damage and staining of the support member can be prevented and the life of the support member can be extended. Since the support member is located outside the lid, the support member can be operated without opening the lid to easily attach and detach the lid from the hinge member, and the lid can be easily removed by removing the lid. can be cleaned.
