Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjusting device for adjusting a gap between upper and lower heating surfaces in a heating cooker for baking a hamburger (food to be heated) from both upper and lower sides.

[0002]

2. Description of the Related Art Conventionally, a heating cooker for double-sided baking of this type has a pair of upper and lower griddles, and both griddles are connected by a hinge at a rear position. And, usually, the upper griddle is held in the state of being opened upward, facing the lower griddle with a slight gap during heating,
A hamburger can be sandwiched between them for cooking. The gap between the two griddles at this time is slightly smaller than the thickness of the hamburger or the like, so that the hamburger or the like can be heated and cooked with a slight pressure.

However, the thickness of hamburgers and the like is not always uniform, and varies depending on the type of products sold. Therefore, if it is possible to set only a certain gap, overbaking may occur depending on the thickness of the hamburger or the like, or conversely, insufficient baking may occur. For this reason, conventionally, a device in which an adjusting device for adjusting a gap is interposed between both griddles has been developed. These were arranged around the griddle so as not to impair the cooking area, and they were usually arranged in a plurality of places so as to form a substantially uniform gap as a whole.

[0004]

However, the conventional gap adjusting devices are generally operated individually,
For this reason, it is necessary to repeat the adjustment operation, and it takes time to adjust. Also, it is difficult to adjust to a uniform gap,
For this reason, there is a problem in that the degree of baking varies depending on the location of the hamburger or the like.

The present invention has been developed and devised in view of such circumstances, and an object thereof is to provide a device capable of easily adjusting a gap between both griddles.

[0006]

[Means for Solving the Problems] The structure of the present invention for achieving the above object comprises a lower griddle on which a food to be heated is placed, and an upper griddle which is openably and closably attached to the lower griddle. In the heating cooker for double-sided baking, the side edge portion of one of the two griddles can contact the other griddle when the upper griddle is closed and has a protruding height thereof. An adjusting member capable of adjusting the gap between the griddles by adjustment is arranged at a plurality of positions, and the respective gap adjusting members are connected so that the projecting operation thereof can be interlocked.

[0007]

Therefore, according to the above construction, since the gap adjusting members are linked so as to be interlocked with each other, by operating one adjusting member, the adjusting actions of the protrusion amounts of the gap adjusting members are synchronized. Is done. Thereby, the gap between both griddles is adjusted at the same time.

[0008]

[Effects of the Invention] The effects of the present invention are as follows. Since the gap adjusting members are interlocked with each other, the adjusting members can simultaneously perform the adjusting operation by one adjusting operation. Therefore, the adjustment work can be smoothly performed in a short time. Further, since the gap between both griddles is automatically made uniform, no skill is required for the work.

[0009]

Embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 5 show a first embodiment of the present invention. The heating cooker of this embodiment is shown in FIGS.
As shown in FIG. 1, a lower griddle 1 and an upper griddle 2 that can be opened / closed in the vertical direction relative to the lower griddle 1 are provided, and a control unit 3 for controlling the heating condition is provided on the lower front side of the lower griddle 1. Are arranged. Both griddles 1, 2
The griddle plates 1a and 2a in FIG. 2 are provided with heating plates 1b and 2b along the same surface, and both have built-in electric heaters (not shown).

The upper griddle 2 is rotatably supported with respect to the main body case 4. The structure of the upper griddle 2 is described below. An outer cylinder 6 is fixedly fitted on the shaft 5, and an arm 7 extends forward from the outer cylinder 6. On the other hand, a supporting convex portion 8 is erected on the heating platen 2b of the upper griddle 2, and is connected to the tip of the arm 7 via a spherical bearing mechanism 9. As a result, the entire upper griddle 2 is suspended and supported so as to be rotatable in any direction.

The upper griddle 2 supported as described above is opened and closed by raising and lowering the handle 10 provided at the front part thereof, and the operating range thereof is such that both griddles 1 and 2 have a slight gap. And a cooking position (the cooking position is held by cam plates 11 to 14 described later) facing each other and an upright fully opened position. In the fully open position, the counter balancer 17 connected to the lever 15 formed on the outer cylinder 6 via the connecting arm 16 holds the entire upper griddle 2 in the upright state.

Next, the adjusting mechanism for adjusting the gap between the two griddles 1 and 2 will be described (see FIG. 1). The front wall surface 18 and the rear wall surface 19 of the upper griddle 2 have a pair of left and right cam plates 11 to 11. 14 are arranged. These cam plates 1
Among the reference numerals 1 and 12, corresponding ones on the front and rear wall surfaces are connected to each other by a connecting rod 20. That is, the connecting rod 20 penetrates the front and rear wall surfaces 18 and 19, and the cam plate 11
-14 are eccentrically attached to both ends thereof, whereby the front and rear corresponding cam plates can interlock with each other.

The left and right cam plates 11 and 12, both of which are arranged on the front side of the griddle and which are arranged on the rear side of the griddle, have a line-symmetrical shape. Each of them is formed in a substantially arc shape, and an eccentric cam portion 21 is formed on the peripheral surface. A part of the peripheral edge of the eccentric cam portion 21 projects downward from the griddle plate 2a of the upper griddle 2 and can come into contact with the upper surface of the griddle plate 1a of the lower griddle 1, and according to the angular displacement of the cam plates 11 and 12. The amount of protrusion can be changed. On the other hand, both cam plates 11,
Joint blocks 40 are fixed near the center of rotation of the cam 12, respectively.
One end sides of link pieces 22 and 23 for interlocking 2 are connected by a nut or the like. On the other hand, both link pieces 2
The other ends of the reference numerals 2 and 23 extend in directions approaching each other and are connected as shown in FIG. That is, the bolt 25 penetrates between the link pieces 22 and 23 with the washer 24 interposed, and is fastened by the nut together with the pullout arm 26. The pull-out arm 26 extends almost right above, and a knob piece 27 is attached to the upper end thereof as shown in FIG. Therefore,
By raising and lowering this knob piece 27, both link pieces 22, 2
The rotational movements of the cam plates 11 and 12 are carried out in synchronism with each other. Further, the knob piece 27 has a locking pin 28 protruding to the back surface of the drawer arm 26, while a plurality of adjustment holes 29 are vertically formed at corresponding positions of the front wall surface 18 of the upper griddle 2. The locking pin 28 can be selectively engaged.

The front wall surface 18 of the upper griddle 2
A U-shaped cover 30 is attached to the lower side of the so as to cover both cam plates 11 and 12.

The first embodiment is constructed as described above. For example, when a hamburger is cooked by heating, the gap between the griddles 1 and 2 is adjusted according to the thickness of the hamburger before cooking. Work is done. In this case,
The knob piece 27 is gripped and the pull-out arm 26 is raised and lowered, and a predetermined adjusting hole 29 is selected to engage the locking pin 28 with a desired adjusting hole 29. Drawer arm 26 described above
Both the link pieces 22 and 23 are synchronously displaced in accordance with the raising and lowering, and the left and right cam plates 11 and 12 are synchronously angularly displaced in conjunction with this. Further, since the cam plates 11 and 12 are connected by the connecting rod 20 even before and after the griddle, as a result, the four cam plates 11 to 14 are angularly displaced in synchronization. Therefore, each cam plate 11-1
The eccentric cam portion 21 of 4 is the griddle plate 2 a of the upper griddle 2.
Since the amount of protrusion from the griddles 1 and 2 is substantially the same and the amount of protrusion is substantially the same, the gap between the griddles 1 and 2 at the cooking position is uniform. Further, since all the cam plates 11 to 14 are rotated only by performing the adjusting operation at one place, the adjusting work can be completed in a short time.

Thus, when the clearance adjusting work is completed, a hamburger or the like is placed on the griddle plate 1a of the lower griddle 1 and the upper griddle 2 is closed, and both griddle plates 1a, 2 are closed.
If the hamburger or the like is sandwiched by a, the hamburger or the like is baked by both griddle plates 1a and 2a that have been electrically heated in advance. However, since the gap is set as desired, the hamburger or the like is properly contacted. The situation is obtained over almost the entire heating area. Therefore, hamburgers and the like can obtain a good cooking condition regardless of where they are placed.

6 and 7 show a second embodiment of the present invention. In the second embodiment, the left and right cam plates 11, 12 are both provided.
The mechanism for interlocking the gears was achieved by combining a rack and a pinion gear. That is, both cam plates 1 on the front wall surface 18 of the upper griddle 2
A pinion gear 33 is rotatably attached between the first and the second terminals. A pair of rack bars 31 and 32 are arranged so as to sandwich the pinion gear 33 from above and below, and rack teeth 31a and 32a that mesh with the pinion gear 33 are formed in the rack bars 31 and 32 along the longitudinal direction. ing. In addition, both rack bars 31, 32
One end side of is inserted into the joint block 40 and fastened with a nut or the like. Furthermore, both rack bars 3
In order to guide the displacement operation of the racks 1, 32, the front wall surface 18 has guide members 34, 3 corresponding to the rack bars 31, 32.
5 are provided. Then, as shown in FIG. 6, the two guide members 34, 35 have the pin 3 at the substantially central position.
7 is stopped, so that the side edges facing the rack bars 31, 32 are bent and the rack bars 31, 32 are bent.
It is a guide piece 36 for guiding 32.

The rotating shaft 38 of the pinion gear 33
The lower end side of the pullout arm 26 is fixedly attached to the, and a knob piece 27 is provided on the upper end side thereof. The locking pin 28 projects from the back surface of the knob piece 27 in the same manner as in the first embodiment, and each adjustment hole 2 is arranged in an arc shape with respect to the front wall surface 18.
9 can be selectively engaged.

In FIG. 6, both cam plates 11 and 12 are shown.
A cover for covering the portion is not shown.

In the second embodiment constructed as described above, when adjusting the gap between the griddles 1 and 2, the knob piece 27 is pinched and the pullout arm 26 is swung. As a result, the pinion gear 33 rotates and the upper and lower rack bars 31, 32 are guided by the corresponding guide members 34, 35 through meshing with the rack teeth 31a, 32a, and are displaced in synchronization with each other in different directions. Further, since both cam plates 11 and 12 are angularly displaced in conjunction with this, it is possible to change the protrusion amount of the eccentric cam portion 21 in synchronization. The left and right cam plates 11 and 12 are also arranged on the rear side of the griddle as in the first embodiment.
Since the front and rear members are connected by the connecting rod 20, all the cam plates 11 to 14 rotate in synchronization,
The gap between the griddles is kept almost uniform.

The other structure is almost the same as that of the first embodiment.
Therefore, the same effect can be exhibited.

FIG. 8 shows a third embodiment of the present invention. In the third embodiment, both cam plates 11 and 12 are linked by a connecting rod 39, and the connecting rod 39 and both cam plates 1 are connected.
The joint block 40 for connecting 1 and 12 is fixed to the cam plates 11 and 12 by a pin 41 so that they can be freely rotated. Further, the pullout arm 26 is fixed to the central portion of the connecting rod 39, and the locking pin 28 of the knob piece 27 is selectively engaged with the desired adjusting hole 29.

In the third embodiment constructed as described above, the pull-out arm 26 is displaced by holding the gripping piece 27, and the locking pin 28 is engaged with the desired adjusting hole 29, so that the left and right and The front and rear cam plates 11 to 14 rotate in synchronization with each other. This makes it possible to adjust the gap between both griddles to a desired gap.

The rest of the structure is almost the same as that of the first and second embodiments, so that the same effect can be obtained.
