Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adjusting device for adjusting a gap between upper and lower heating surfaces in a heating cooker for baking hamburgers and the like (food to be heated) from both upper and lower sides.

[0002]

[Prior art]

 Conventionally, this type of double-sided heating cooker has a pair of upper and lower griddles, and both griddles are connected by a hinge at the back side position. Usually, the upper griddle is kept open upward, and when cooking, it faces the lower griddle with a slight gap, and a hamburger or the like is sandwiched between them to allow cooking. . At this time, the gap between the two griddles is slightly smaller than the thickness of the hamburger, etc., so that the hamburger, etc. can be 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 conversely, underbaking may occur. For this reason, conventionally, there has been developed one in which an adjusting device for adjusting the gap is interposed between both griddles. These were placed around the griddle so as not to impair the cooking area, and they were usually placed in multiple locations so that the entire gap was almost uniform.

[0004]

[Problems to be solved by the device]

 However, since the conventional gap adjusting device is generally operated individually, it is necessary to repeat the adjusting operation, which requires time and effort for adjustment. In addition, it is difficult to adjust the space evenly, and therefore, there is a problem that the baking amount varies depending on the place where the hamburger is placed.

The present invention has been developed and devised in view of such circumstances, and an object thereof is to provide an apparatus 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 is for double-sided baking including a lower griddle on which a food to be heated is placed and an upper griddle that is openably and closably attached to the lower griddle. In the heating cooker, the side edge of one of the two griddles can come into contact with the other griddle when the upper griddle is closed, and the protruding height between the two griddles can be adjusted to adjust the distance between the griddles. A plurality of adjusting members capable of adjusting the gap are arranged at a plurality of positions, and the protruding members of the gap adjusting members are connected so as to be capable of being linked.

[0007]

[Action]

 Therefore, according to the above configuration, since the gap adjusting members are linked to each other in an interlocking manner, the operation of adjusting the protrusion amount of each gap adjusting member is performed in synchronization by operating one adjusting member. . As a result, the gap between both griddles is adjusted at the same time.

[0008]

[Effect of device]

 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.

【Example】

 Embodiments embodying the present invention will be described below in detail with reference to the drawings. 1 to 5 show a first embodiment of the present invention. The heating cooker of this embodiment has a lower griddle 1 and a vertical opening / closing operation as shown in FIGS. A control unit 3 for controlling the heating condition is arranged on the front side of the lower surface of the lower griddle 1. The griddle plates 1a and 2a of both griddles 1 and 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 will be described below. An outer cylinder 6 is fixedly fitted to the shaft 5, and an arm 7 extends forward from the outer cylinder 6. On the other hand, a support 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 that it can rotate 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 has a slight gap between the two griddles 1 and 2. And the cooking position (the cooking position is held by cam plates 11 to 14 described later) facing each other and the upright fully opened position. At 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, an adjustment mechanism for adjusting the gap between the two griddles 1 and 2 will be described (see FIG. 1). A pair of left and right cam plates 11 are provided on the front wall surface 18 and the rear wall surface 19 of the upper griddle 2. ~ 14 are arranged. Of the cam plates 11 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 plates 11 to 14 are eccentrically attached to both ends thereof, so that the corresponding cam plates can be interlocked 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 the angular displacement of the cam plates 11 and 12 can be made. The amount of protrusion can be changed accordingly. On the other hand, a joint block 40 is fixed near the center of rotation of both cam plates 11 and 12, and one end side of link pieces 22 and 23 for interlocking the left and right cam plates 11 and 12 has a nut. Are connected by etc. On the other hand, the other end sides of both link pieces 22 and 23 extend in directions approaching each other and are connected as shown in FIG. That is, the bolt 25 is penetrated with the washer 24 interposed between the link pieces 22 and 23, and the bolt 25 is tightened together with the pullout arm 26 by the nut. 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 the knob piece 27, the pivotal movements of the cam plates 11 and 12 are simultaneously performed via the link pieces 22 and 23. The knob piece 27 has a locking pin 28 projecting from the rear 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. , Can be selectively engaged with the locking pin 28.

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

The first embodiment is configured as described above. For example, when a hamburger or the like 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 to select a predetermined adjustment hole 29 to engage the locking pin 28 with the desired adjustment hole 29. The link pieces 22 and 23 are synchronously displaced as the pulling arm 26 is raised and lowered, 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, the eccentric cam portion 21 of each of the cam plates 11 to 14 can obtain the amount of protrusion of the upper griddle 2 from the griddle plate 2a at the same time, and substantially the same amount of protrusion can be obtained. The gap between the 1 and 2 becomes uniform. Further, since all the cam plates 11 to 14 can be rotated only by performing the adjusting operation at one place, the adjusting work can be completed in a short time.

Thus, when the clearance adjustment 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 the hamburger plate or the like is sandwiched by both griddle plates 1a and 2a. For example, the hamburger steaks are baked by both griddle plates 1a and 2a that have been electrically heated in advance. However, since the gaps are set as desired, the appropriate contact condition for the hamburg steaks, etc. is almost over the entire heating area. Got over. Therefore, hamburgers and the like can be in good working condition regardless of where they are placed.

6 and 7 show a second embodiment of the present invention. In the second embodiment, a mechanism for interlocking the left and right cam plates 11, 12 is achieved by a combination of a rack and a pinion gear. It was something I tried to do. That is, the pinion gear 33 is rotatably mounted between the cam plates 11 and 12 on the front wall surface 18 of the upper griddle 2. 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. Has been done. Further, one end sides of both rack bars 31, 32 are inserted into the joint block 40 and fastened with nuts or the like. Further, in order to guide the displacement operation of both rack bars 31, 32, guide members 34, 35 are provided on the front wall surface 18 so as to correspond to the rack bars 31, 32. Then, as shown in FIG. 6, the guide members 34 and 35 are pivotally supported as a whole by being fixed to the pins 37 at substantially central positions thereof, and the side edges facing the rack bars 31 and 32 are bent. It is a guide piece 36 that guides the rack bars 31 and 32.

The lower end side of the pullout arm 26 is fixed to the rotary shaft 38 of the pinion gear 33, and a knob piece 27 is provided on the upper end side thereof. A locking pin 28 projects from the rear surface of the knob piece 27 in the same manner as in the first embodiment, and can be selectively engaged with each adjusting hole 29 arranged in an arc shape with respect to the front wall surface 18. .

Note that in FIG. 6, a cover for covering both the cam plates 11 and 12 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 different directions in synchronization with each other. 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, and the front and rear members are connected by the connecting rod 20, so that all the cam plates 11 to 14 are connected. Rotate in synchronism with each other, so the gap between the griddles is maintained almost even.

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

FIG. 8 shows a third embodiment of the present invention. In the third embodiment, both cam plates 11, 12 are linked by a connecting rod 39, and the connecting rod 39 and both cam plates 11, 12 are linked together. A joint block 40 for connecting the and is fixed to the cam plates 11 and 12 by a pin 41 so as to be freely rotatable. Further, the pull-out 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 configured as described above, the pulling arm 26 is displaced by holding the gripping piece 27, and the locking pin 28 is engaged with the desired adjusting hole 29. 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 other structures are almost the same as those of the first and second embodiments, and thus the same operational effect can be exhibited.
