Since it is composed of point parts, there is a problem that the number of parts is large and the structure and assembly are complicated, resulting in high cost. Not only that, since the door 1 is opened to the front side as shown in FIG. 6, a space corresponding to the width of the door 1 is required on the front side of the outer structure when the food is to be put in or taken out. . Therefore, it has a large occupied area and is unsuitable for placing in a narrow space. Moreover, the glass retainer of the door 1 is made of metal and faces the cooking chamber 3 and becomes hot. However, since it is opened and exposed to the front side as described above, when the food to be cooked is put in or out of the cooking chamber 3. In addition, there is a risk that the fingers may come into contact with the above-mentioned glass retainer in a high temperature state and get burned.

Therefore, an object of the present invention is to provide a cooker which can form an outer shell with a small number of parts, has a small occupied area when a food item is put in and out, and is less likely to be burned when the food item is put in and out. It is in.

[Means for Solving the Problems]

In order to solve the above-mentioned object, the cooker according to the present invention is

A case body having a cylindrical shape and accommodating a cooking chamber structure, a pair of left and right fixed side plates, a viewing window formed of a window frame and a transparent plate, and a part of a heating plate that closes the entrance / exit of the case body are used for cooking in the present invention. Configure the outer structure of the vessel. For this reason, a part of the case body doubles as the case front plate, which is required in the conventional technique, and the viewing window cannot be opened and closed. It can also serve as an edge.

Then, the cylindrical case body is pivotally operated from the fixed position to the open position around the pivot with the pivoting members connected to both ends thereof. In the fixed position, the viewing window faces the opening of the cooking chamber structure, and the entrance / exit of the case body opposes a part of the reflector of the cooking chamber structure, and the entrance / exit is closed by this part. . The peep window facing the opening allows the state of the food to be cooked on the grill to be visually recognized through the window. Then, when the case main body is rotated from the fixed position to the open position, the doorway faces the openings, and it becomes possible to put in and out the food to be cooked facing the grill in the cooking chamber through the doorways and the openings. A part of the reflector faces the viewing window.

As described above, the case main body provided concentrically with the cooking chamber structure is rotated so that the entrance and exit of the case body face the opening of the cooking chamber structure so that the food can be taken in and out. You don't need a door with a peephole to open to. Therefore, a space for opening and closing the door is not required on the front side of the outer shell structure, and the portion that is heated hot when the food to be cooked is put in or out is not exposed to the outside.

By doing so, it is movably supported along the front-rear direction.

A pair of rod-shaped electric heaters are used as the heat source 19, which are located above and below the grill 18 and are supported between the main frames 12 and 13. That is, the heat source 19 has its both ends having the glass 19a passed through the through holes 23 respectively provided in the main frames 12 and 13, and is connected to the main frames 12 and 13 via the glass 19a. Incidentally, reference numeral 24 in FIG. 1 denotes a conductive plate which electrically connects a pair of upper and lower heat sources 19 electrically in series.

Further, in FIG. 1, FIG. 4 and FIG. 5, reference numeral 25 denotes a pair of left and right fixed side plates, which have a flange over the entire circumference and form a circular shape. The legs 26 made of resin are respectively screwed to the outer surface of the plate portion of each fixed side plate 25, and the resin handles 27 for carrying are respectively screwed to the upper outer surface of each fixed side plate 25. In addition, one of the fixed side plates
A time switch 28 is screwed to 25, and a power cord 29 is inserted and attached. The time switch 28 determines the energization time of the heat source 19, and 28a in FIGS. 1 to 3 is an operation knob of the time switch 28.

These fixed side plates 25 are connected to the cooking chamber structure 11 via the connecting plate 30.
I support you. That is, the connecting plates 30 formed by bending a sheet metal are screwed to the outer surfaces of the main frames 12 and 13, and the connecting plates 30 are screwed to the inner surface of the fixed side plate 25. The connecting plate 30 secures a space between the fixed side plate 25 and the main frame 13 for housing the switch 28.

And, the connecting plates fixed on both sides of the cooking chamber structure 11 respectively.
Axis 31 is attached to each of 30. That is, Axis 31
Is a stepped screw, and the threaded portion is inserted into the shaft mounting hole 30a located on the center line of the cooking chamber structure 11, and the nut 32 is screwed into this threaded portion to attach it to the connecting plate 30. Has been. A rotating member 33 is rotatably supported on the pivot 31.

The rotating member 33 is provided with reinforcing flanges on the upper and lower edges of a strip-shaped metal plate, fixing holes 33a at the bent portions at both ends, and U-shaped cam grooves 34 on both sides of the pivot 31. Has been formed. The left and right rotating members 33 are formed by the same press die. The shaft portions 18a of the mesh 18 are slidably inserted into the cam grooves 34 on the rear side of the rotating member 33.

Further, as shown in FIGS. 2 and 3, a connecting hole 35 is provided below the front cam groove of the rotating member 33, and the rotating hole provided in the connecting plate 30 is provided in this hole 35. A stepped screw 37 that is inserted through the restriction hole 36 is screwed. Rotation restriction hole 36
Is an arcuate hole centered on the shaft mounting hole 30a, and the diameter of the non-threaded portion of the stepped screw 37 is a rotation regulating hole.
The width is approximately equal to the width of 36 and is guided along the rotation restricting hole 36. And by this structure,
By the play caused by the fitting of the pivot 31 and the rotating member 33,
The rotating member 33 is prevented from rotating while swinging around the pivot 31, so that the case body described later can be smoothly rotated.

Reference numeral 38 is a cylindrical case body with both ends open,
The diameter thereof is larger than the diameter of the cooking chamber structure 11 having a cylindrical shape, and the case main body 38 houses the cooking chamber structure 11. Both ends of the rotating member 33 are connected to both ends of the case body 38, respectively. This connection is made by a screw 39 which is inserted through an end portion of the case body 38 and screwed into the fixing hole 33a of the rotating member 33. Therefore, the case body 38 is rotatable about the pivot 31 via the rotating member 33, but the rotation restricting hole 36 restricts the rotation from the fixed position to the open range. Moreover, the openings at both ends of the case body 38 are closed by the fixed side plates 25, respectively.

Further, the case main body 38 has a non-openable viewing window 40 that is located on the front side and faces the opening 17 in the position shown in FIG.

In addition, the case body 38, the viewing window 40 fixed to this,
The pair of left and right fixed side plates 25 and the reflection plate 16 as the bottom plate form the outer structure of an oven toaster. The viewing window 40 includes a window frame 41 and a transparent plate 42 made of heat-resistant glass or the like, which sandwiches the transparent plate 42 between the hole edge 43a of the window hole 43 provided in the case body 38 and the window frame 41 overlapping with this. The window frame 41 and the hole edge 43.
It is provided by fixing to a. The window frame 41
Is fixed without using screw parts by inserting a tongue projecting from the back surface into a slit provided in the hole edge 43a and bending it, but using fixing parts such as screws. The window frame 41 may be fixed. A resin handle 44 is screwed to the lower edge of the observation window 40, for example. The handle 44 is used when rotating the case body 38, and may be provided so as to project on the outer peripheral surface of the case body 38.

Further, the case body 38 is located on the front side in the open position state shown in FIG.
Is located away from the viewing window 40. This entrance
In the state where the case main body 38 is in a fixed position, 45 is opposed to the reflection plate 16 as the bottom plate and is closed.

In the round oven toaster having the above-described configuration, a case body 38 having a cylindrical shape and accommodating the cooking chamber structure 11, a pair of left and right fixed side plates 25, a viewing window 40 including a window frame 41 and a transparent plate 42, and a reflection plate. Since 16 constitutes the outer structure of the toaster oven, a part of its case body 38,
That is, in FIG. 1, the portion between the lower edge of the observation window 40 and the front edge of the entrance / exit 45 also serves as the case front plate, which is required in the conventional technique. Furthermore, since the viewing window 40 is fitted into the window hole 43 and cannot be opened, the transparent plate 42 is also held by the hole edge 43a of the window hole 43 in the case body 38. Therefore, the total number of parts forming the outer shell structure is reduced to 6 points, the structure and the assembly are simplified, and the manufacturing cost can be reduced.

The cylindrical case body 38 is a rotating member connected to both ends thereof.
Along with the pivot 33, the pivot 33 is rotated from the fixed position to the open position. The state of the home position is shown in FIG. 4, and in this state, the viewing window 40 of the case main body 38 is located at the front side as shown by the alternate long and short dash line in FIG.
Of the case main body 38, as well as facing the opening 17 of
45 is positioned on the lower side and faces the reflection plate 16 of the cooking chamber structure 11 so as to be closed. Therefore, the opposite openings
Through the window 17 and the viewing window 45, the inside of the cooking chamber such as the state of the food on the grill 18 can be visually confirmed. Further, in the state where the case main body 38 is in the fixed position as described above, the shaft portion 18a of the grill 18 is engaged with the rear end portion of the cam groove 34 of the connecting plate 30,
The entire grill 18 is arranged so as to be housed inside the cooking chamber structure 11. (See Figure 2).

Then, when the food to be cooked is put in or taken out, the case main body 38 is rotated about the pivot 31 from the fixed position to the open position shown in FIG. Then, since the entrance / exit 45 is located on the front side and faces the opening 17 as shown by the chain double-dashed line in FIG. 2, the food to be cooked is directed to the grill 18 in the cooking chamber through the entrance / exit 45 and the opening 17. You can go in and out. Along with this, the viewing window 40 is arranged on the upper side and faces the reflection plate 14.

When the case body 38 is rotated as described above, the cam groove of the rotating member 33 is formed.
Since 34 is displaced to the state of the two-dot chain line, the shaft portion 18a of the mesh 18 slides along the guide hole 21 accordingly, and the engagement position with respect to the cam groove 34 is from the rear end portion of the cam groove 34. It changes to the front end. Therefore, the front side of the grill 18 is projected forward through the opening 17 and the inlet / outlet port 45. This makes it easier to put the cooking target in and out of the grill 18.

Of course, when the case main body 38 is rotated downward from the state shown in FIG. 5, the grill 18 is automatically immersed in the cooking chamber structure 11 in association with the downward rotation.

Moreover, when the case body 38 is rotated, the rotation member 33 that supports and rotates the case body 38 can swing about the pivot axis in the axial direction by the rotation restriction hole 36 and the stepped screw 37 that slides the rotation restriction hole 36. The inner circumference of the case body 38 is the main
It prevents you from competing against the outer surface of 2,13. As a result, the case main body 38 can be smoothly rotated while maintaining the concentricity with the central axis of the cooking chamber structure 11.

Then, rotate the case body 38 as described above and
By allowing 45 to face the opening 17, food to be cooked can be put in and taken out, so that there is no need for a door with a viewing window that opens to the front side. Therefore, since a space for opening and closing the door is not required on the front side of the outer structure, the exclusive area required for putting in and out the food to be cooked can be reduced, and it is suitable for use in a narrow space.

Along with this, as described above, the part that is heated hot when the food to be cooked is put in and out by the omission of the door is the cooking chamber structure 11
Since it is not exposed to the outside, there is little risk of being burned during handling, it is safe and the usability is improved.

The present invention is not limited to the above-described embodiment, and for example, the interlocking relationship between the grill 18 and the case body 38 may be eliminated. In this case, it is preferable that the opening 17 is provided in the front portion of the cooking chamber structure 11 so as to face upward in order to facilitate the loading and unloading of the food to be cooked. Further, the reflectors 14 to 16 may be integrated. Further, the heat source 19 may be a gas burner or the like, and may be arranged only above or below the grill 18. Moreover, the pivot 31 that pivotally supports the rotating member 33 may be directly attached to the main frames 12, 13 or the fixed side plate 25. When the fixed side plate 25 is made of heat-resistant resin, it can be formed integrally with the leg 26. Also, with the case body 38 in place, place the access port 45
Alternatively, the case main body 38 may be provided so as to be located above the 38 and the case main body 38 may be rotated downward so that the inlet / outlet port 45 faces the opening 17.

〔The invention's effect〕

According to the present invention having the above-described structure, a part of the case body which is cylindrical and rotatable is also used as a case front plate which is conventionally required, and the viewing window cannot be opened. Since the transparent plate can be held by the edge of the window hole in the case body, the number of parts of the outer structure can be reduced accordingly, and the structure can be simplified. And
By rotating the case body, the peep window and the entrance / exit can be selectively opposed to the opening of the cooking chamber structure, so that the door with the peep window can be omitted. For this reason, a space for opening and closing the door is not required on the front side of the outer shell structure, the exclusive area required for putting in and out the food to be cooked can be reduced, and it is also suitable for use in a narrow space. Further, by omitting the door with the peep window, the heated portion such as the inner surface of the peep window is not exposed to the outside when the cooked food is taken in and out, so that there is little possibility of being burned during handling.
