Description

Heating cooker technical field

The present invention relates to a heating cooker in which a surface heater is attached in contact with a cooking base material, and a demonstration workbench provided with the heating cooker.

Background art

As shown in Fig. 5, a banana-thin pancake (6) packed with bean jam is known. book

In order to bake the pancake, a pair of template plates (21) (22) which are rotatably connected to be openable and closable are used as shown in FIG. The mold plates (21) and (22) are provided with mold holes (23) and (24) which form a banana-shaped space when closed.

Pour the pancake dough into both mold holes (23) and (24) and add bean paste. When the dough is slightly burned, close the templates (21) and (22) and bake.

The dough in both mold holes (23) and (24) is united and baked into a banana shape.

A gas or electric heater is often used as a heat source for heating the template (21) (22). However, when performing pancake demonstration sales at department stores, etc., in order to prevent the floor air conditioning load from becoming excessive, and from the viewpoint of safety, a flat-type electric heater (32) using a resistance heating wire (32) should be used. Hereinafter, this is referred to as a surface heater).

As shown in FIG. 4, the surface (3) is formed by winding a resistance heating wire (32) around a heat-resistant insulating plate (31) such as mica. The surface heater (3) is covered on both sides with a metal outer plate (34) such as a stainless steel plate via an insulating material, and penetrates the outer plate (34) to project the connection terminals (33) and (33). Has been established.

The resistance heating wires (32) are not wound at equal pitch, The pitch winding becomes coarser toward the center of (31). This is because when the resistance heating wire (32) is wound at a constant pitch, heat is trapped in the center of the surface (3), the temperature rises from both ends, and the template () (22) is evenly heated. It is not possible.

The mask (3) is fixed to the back of each template (21) (22) (see Fig. 3).

When the entire surface of the surface heater (3) is in close contact with the template (21) (22), the heat generated by the surface heater (3) is efficiently transmitted to the template (21) (22), 3) Excessive temperature rise of itself is suppressed and power consumption can be suppressed. In addition, the exterior plate (34) on the surface of the surface heater (3) does not discolor and maintains its beauty.

When a gap is formed between the surface heat sink (3) and the template, the portion where the gap is generated loses heat transfer to the template (21) (22) ′, and wastefully consumes power. . Not only that, heat is stored inside the surface heater (3), and the exterior plate (34) turns dark brown due to high heat, deteriorating the aesthetic appearance. The resistance heating wire (S2>) on the surface (3) 'may break, and the surface heater (3) may need to be replaced.

Therefore, the surface (3) must be fixed to the template (21) (22) so as to be as flat as possible. However, it is impossible to penetrate the surface heater (3) with bolts and screw them directly to the template (21) (22) because the internal resistance heating wire (32) is broken.

For this reason, conventionally, as shown in FIG. 6, a plurality of locations on the outer peripheral portion of the surface heater (3) are pressed and fixed by the holding bracket (42) and the port (41). The greater the number of pressed points, the higher the degree of adhesion between the surface heater (3) and the firing mold.

However, when the number of Porto (41) increases, it takes time to remove the mask (3).

Carbide sticks to the mold plates (21) and (22) in layers due to the burning of the edible oil or cake material applied to the mold holes (23) and (24). This stuck To prevent the char from exfoliating and mixing into the pancakes, it is necessary to periodically remove the stuck char. This carbide is removed by immersing the templates (21) and (22) in a tank of a strong cleaning solution such as caustic soda. It is necessary to remove overnight (3).

For this reason, mounting and removing the surface heater (3) is required to be easy and hassle-free, and the conventional method of mounting the surface heater does not satisfy this requirement.

Further, when the outer peripheral edge of the surface heater (3) is fixed to the template (21) by the presser fitting (42) and the bolt (41), when the surface heater (3) thermally expands, the surface of the template (21) is removed. The growth in is prevented. As a result, the central portion of the surface heater (3) bends so as to float from the rear surface of the template (21), and a gap is formed between the surface heater (3) and the template (21).

The present invention discloses a cooking device for baking pancakes that can solve the above problems, and a workbench equipped with the cooking device. Of course, besides the purpose of baking pancakes, any cooking device that uses a heater for heating can be used.

Disclosure of the invention

In the heating cooker of the present invention, the back plate (20) of a heating base material (2) such as a pair of pancakes (2ϋ (ϋ)) is bent shallowly and gently to form a concave. It is characterized in that the surface is pressed and pressed against the bottom of the concave surface (3).

The cooking cooking demonstration work table of the present invention includes a pair of template plates (21) and (22) as one set, one side of which is connected with a hearse, and one or more sets of template plates () and (Π) (2) With the (2) and (3) open, they are spaced apart from each other so as not to interfere with the adjacent set of templates, and the two templates (21) and (22) are urged by a panel in the closing direction.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Figure 1 shows a workbench (1) for demonstration sale of banana-shaped pancakes, and templates (21) and (22) for baking pancakes.

The workbench (1) is configured by providing legs (12) in a rectangular shallow bottom housing (11) having an upper surface opening. One or more sets of rectangular templates (21) and (22) are set in the housing (11).

The template plates (21) and (22) are rectangular with a length of about 57 cm, a width of about 18.5 cm, and a thickness of 2 cm. It is made. However, it is needless to say that the embodiment can be made of a general template material such as iron, copper, and gunmetal.

The mold plates (21) and (22) constitute a pair, and the two mold plates (21) and (Π) use brackets (25) and (26) protruding from the longitudinal side edges of the common rotation support shaft. It is connected to (27) so that it can be opened and closed.

When the mold plates (21) and (、) are closed, the mold plates (21) and (22) have mold holes (23) that form a mold cavity corresponding to the shape of the banana-shaped pancake (6) in FIG. ) (24) is provided.

The support shaft (27) is positioned at a distance such that the template (21) (22) does not hit the template of the adjacent set when the template (21) (22) is opened. Supported by (1). A handle (7) is protruded from one of the templates (21) and (22) of each set, and a closing lock is provided at a free end of each of the templates (21) and (22). Means (71) are provided. Holding the handle (7), rotate the template (21) on the handle side to the mating template (22) side about the rotation support shaft (27) as shown in Fig. (22) can be closed and locked by the hook means (71).

Torsion springs (28) and (29) are fitted on both ends of the rotation support shaft (27), respectively. One torsion panel (28) closes one template (22) in the closing direction, and the other torsion spring. (29) urges the other template (21) in the closing direction. This facilitates the opening and closing operations of the template (21) (22).

However, the strength of the torsion panel (28) (29) 'is not strong enough to erect the template (2Ϊ) (22), but is a spring force enough to reduce the force required for manual rotation.

The forces of the torsion panels (28) and (29) are balanced, and the stencils (21) and (Π) are locked in the closed state, and the rotating support shaft (27) is locked as shown by the two-dot chain line in FIG. Even if you release your hand from the handle (7) while standing upright, you can keep upright.

On the mold plates (21) and (22), the surface opposite to the mold hole (referred to as the "back surface") is a surface heater.

It is the heating surface according to (3). The back surface (20) is shallowly concave with a gentle arc from the side edges along the longitudinal direction to the center in the width direction. The maximum depth of the recess on the back (20) is about 2-3 mm in width.

The surface heater (3) is flat and has a width substantially equal to the width of the template (2 1) (22), as in the conventional case shown in FIG. 4, and the length is the template (21) (22) It is a rectangle that is slightly shorter than that, and has a thickness of about 5 mm.

The surface heater (3) is pressed by a bar-shaped pressing member (4) so that the center in the width direction is in close contact with the rear surface of the template (21) (Π) over the entire length. Presser member

Both ends of (4) are screwed (41) to both ends of the template (21) (Π).

The holding member (4) is curved so that the center part hangs down a little. If the surface heater (3) is pressed down by screwing and elastically deforming the surface heater (3), the surface heater (3) can be more effectively brought into contact with the template (21) (22). If the screw holes of the holding member (4) are elongated, it is possible to cope with the expansion due to the thermal expansion of the holding member (4).

The means for pressing the holding member (4) is not limited to screwing. For example, an end of the pressing member (4) may be hooked by a hook (not shown) rotatably or undulatingly attached to an end of the template (21) (22).

The surface heater (3) is elastically deformed by being pressed by the holding member (4) and closely adheres to the back surface (20) which is a curved concave surface of the heating base material (2). The surface heater (3) presses the back surface (20) over the entire surface due to the reversion force of the surface heater (3) to return to the flat original shape.

A heat insulating cover (5) for preventing the heat of the surface heater (3) from escaping to the outside is attached to the template (21) (22) (see FIG. 2). The heat retaining cover (5) is a flat housing having side plates (51) on four sides of a cover plate (50) corresponding to the sizes of the template plates (21) and (22) at right angles to the cover plate (50). The working plate (51>) is screwed to the side surface of the template (21) (22).

To make pancakes, apply power to the surface heater (3) and heat both mold plates (21) and (22) heated to about 180 ° C to the bottom plate (13) of the workbench (1). To open.

Pour the pancake dough into the mold holes (23) and (24) of the template plates (21) and (22), and further put the bean jam inside one of the template plates (22).

When the surface in contact with the mold holes (23) and (24) of the dough is slightly burned, hold the handle (8) with the handle (8) and rotate the handle plate (21) around the rotation support shaft (27). Flip it over and place it on the mating template (22) side.

Locking the pair of template plates (21) and (22) in an overlapping state by the locking means (71) When the dough is baked with the template plates (21) and (22) folded down to one side as described above, The bean jam shifts from the center of the pancake (6). Therefore, the templates (21) and (22) locked in the overlapping state are turned 180 ° to the opposite side. When the reversing operation of the template (21) (22) is repeated several times, the banana-shaped bakery (6) with the bean paste positioned at the center is baked.

The template plates (21) and (22) are heated by a surface heater (3) mounted on the back surface (20) of the template plate (3), which is elastically deformed by the pressing of the bar-shaped pressing member (4). (21) It is in close contact with the back surface (2Q), which is the curved concave surface of (22) The surface heater (3) itself comes into contact with the back surface (20) due to the elastic restoring force of the surface heater (3) trying to return to its original shape. Is pressed, so that the formation of a gap between the back surface (2) and the back surface is prevented.

As a result, the entire template (21) (22) is evenly heated without excess or shortage, and the pancake (6) is baked neatly without spotting.

Also, when a gap is partially formed between the surface heater (3) and the template (21) (22), the partial heat from the surface heater (3) to the template (21) (22) is reduced. Due to poor communication, some of the surface (evening (3) :) heats up excessively. However, in the case of the present invention: a cooking device, there is no fear of this. Therefore, the temperature of the surface heater (3) is maintained at 170 to 180 ° C. Therefore, the exterior plate (34) of the surface heater (3) turns dark brown due to excessive temperature rise and impairs the appearance, and the resistance heating wire (32) inside the surface heater (3) breaks. Can be prevented.

Since the temperature rise of the surface heater (3) itself does not exceed 200, it does not affect the elastic restoring force of the exterior plate (34) of the surface heater (3). The templates (21) and (22) are made of aluminum, which is lighter than iron, copper and gunmetal, and the templates (21) and (Π) are connected to each other by the torsion panel (28> (29)). It is biased in the closing direction .. Therefore, the reversing operation of the template (21) (22) with the handle (7) can be performed lightly.

In demonstration sales while showing the pancake manufacturing process at department stores, etc., The number of times that the templates (21) and (22) are turned over is hundreds of times, which is a considerable labor. The fact that the template (2 1) (22) can be turned over lightly can greatly reduce fatigue and can be easily applied to elderly people.

In addition, the operation of reversing the templates (21) and (22) is a performance that enhances the customer's willingness to purchase. It is a big factor to produce deliciousness.

In the embodiment of the present invention, the shapes of the mold holes (23) and (24) of the mold plates (21) and (Π) are not limited to the “banana shape”, but may be various shapes such as “maple shape” and “bale shape”. It can be implemented at

Further, in the embodiment, mating heated preform planar heater (3) is heated (2) was a mold cavity to bake pancakes (23) (24) with the template (21 :) (22) _sigma However, the heating base material (2) may be of any type, such as a flat iron plate, a grooved iron plate for grilling steak meat, etc., as long as the surface heater (3) can be directly pressed and contacted with the heating base material (2). Regardless.

Industrial applicability

The surface heater (3) is elastically deformed by pressing and is brought into close contact with the back surface (20) which is a curved concave surface of the heating base material (2). The surface heater (3) itself presses the back surface (20) by the elastic restoring force of the surface heater (3) to return to the original shape. Therefore, it is possible to suppress a gap from being formed between the back surface (20). .

For this reason, the heat generated by the surface heater (3) is efficiently transferred to the heating base material (2), so that power consumption is suppressed and energy saving is achieved. Also, the surface heater (3): prevents the temperature of the heater from becoming excessively high partially, causing the exterior plate (34) of the surface heater (3) to turn brown or to break the resistance heating wire (32). it can.

When the surface heater (3) and the heating base material (2) are rectangular, and the central part in the width direction of the surface heater (3) is pressed down by the bar-shaped pressing member (4) over the entire length, the pressed portion becomes At least, the surface heater (3) can be effectively brought into close contact with the back surface (20) and pressed. Also, as compared with the conventional method of mounting the surface heat sink (3.) on a template by using a large number of ports and holding brackets, it can be installed easily and without much trouble. Therefore, the cleaning operation of the template can be performed in a short time, which requires a step of removing the surface heater, a step of immersing the template in the cleaning liquid, and a step of attaching the surface heater again.

When baking confectionery dough in the mold space formed inside by closing the pair of template plates (21) and (22), it may be necessary to turn over the template plates (21) and (22). However, in the work table (1) of the present invention, since the templates (21) and (22) are urged in the closing direction by the torsion panels (28) and (29), the templates (21) and (22) 22) The weight is reduced. Therefore, the manual reversing operation of the template (21) ()) can be performed lightly.
