BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided pottery cooker that simultaneously grills hamburgers and the like from both sides.

[0002]

2. Description of the Related Art Heretofore, as a double-sided pottery cooker of this type, one shown in Japanese Patent Application No. 63-329899 by the present applicant has been known.

The double-sided pottery cooker disclosed in the above publication has a lower griddle having a heat source in the lower part thereof, and a shaft support portion which is disposed above the lower griddle with a predetermined gap between the lower griddle and the rear griddle when not in use. And an upper griddle which is rotated to a position apart from the lower griddle while drawing an arc around the upper griddle and which suspends and supports the upper griddle and which extends to the opposite side of the upper griddle with the shaft support portion interposed therebetween. The front end was constituted by a beam forming a handle on the front surface of the upper griddle, and a weight hanging from the rear end of the beam.

In this structure, when the upper griddle is used, the handle formed at the front end of the beam is grasped,
When the beam is pulled toward the lower front part with the shaft support as a fulcrum, the upper griddle supported by the beam comes down above the lower griddle. At this time, the beam supports the upper griddle in front of the shaft support, but supports the weight behind the shaft support, so that when one moves down, the other moves up to balance.

On the other hand, a preset gap is formed between the upper griddle and the lower griddle, and by placing a hamburger or the like having a predetermined thickness on the lower griddle, the hamburger can be provided with a predetermined thickness from both sides. Bake.

[0006]

In the above-mentioned conventional double-sided grill cooking device, the upper griddle has to be raised and lowered manually, which is a problem.

Further, if the raising and lowering is automated, it is conceivable that a hand or a finger may be caught between the upper griddle and the lower griddle which are maintained at a high temperature, and such an accident must be eliminated.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a double-sided grill cooker capable of automatically raising and lowering the upper griddle while maintaining safety.

[0009]

In order to achieve the above object, the invention according to claim 1 provides a lower griddle having a heating plate having a heating means disposed on the upper surface thereof, and a grip for projecting forward from a front end portion. A heating plate having a handle and having heating means is disposed on the lower surface, and an upper griddle supported so as to be able to approach and separate while drawing an arc with respect to the lower griddle about a support shaft at the rear end, A drive mechanism for rotating the upper griddle in a predetermined direction about the support shaft to move the upper griddle closer to and away from the lower griddle, and an upper griddle provided by a gripping handle of the upper griddle by the drive mechanism. And a control switch for instructing the drive of the.

[0010]

In the invention according to claim 1 configured as described above, the drive mechanism causes the upper griddle to rotate in a predetermined direction about the support shaft so that the upper griddle approaches and separates from the lower griddle. However, when instructing this drive, the operation switch is arranged on the grip handle that projects forward from the front end of the upper griddle, and the operator must place his hand on the grip handle in front of the upper griddle. To operate.

That is, when the operator puts his / her hand on the grip handle of the rotationally driven upper griddle and operates the operation switch, the upper griddle is rotationally driven in a predetermined direction by the drive mechanism in front of the operator.

[0012]

As described above, according to the present invention, the upper griddle is rotationally driven only by operating the operation switch, and at this time, the operator's hand is placed at a position apart from between the upper griddle and the lower griddle. Since the upper griddle cannot be driven unless it is placed, it is possible to provide a double-sided grill cooker that can be operated easily while maintaining safety.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 are views showing the appearance of a double-sided pottery cooker according to an embodiment of the present invention. The double-sided pottery cooker shown in the present embodiment has two upper griddles 20a and 20b arranged on one lower griddle 10, and the lower griddle 10 and the upper griddle 20 each have an electric heater as a heat source.

In the figure, the lower griddle 10 holds a lower hot plate 12 having an electric heater built in above the double-sided grill cooker main body 11 in a state of being exposed upward. An upper griddle 20 is held above.

The upper griddle 20 is the lower griddle 10
Parallel side frames 21a extending in the front-back direction of the
21b, the side frames 21a, 21b are connected at the front end portion by a gripping handle 22 and at the rear end portion by a cross frame 23 in which a middle turning hook 23a is formed. 24 are formed.

The rear end of the support frame 24 is supported by both sides of the double-sided pottery cooker body 11 and penetrated by a support shaft (support shaft) 13 arranged in the lateral direction, and the support frame 24 is supported by the support shaft 13. It is possible to rotate within a predetermined range around. In addition, an upper heating plate 25 having an electric heater built therein is supported on the support frame 24 so as to be movable by a small distance in a direction perpendicular to the surface formed by the support frame 24. By changing the relative position to the heat plate 25, the gap between the lower heat plate 12 and the upper heat plate 25 when the support frame 24 is rotated to a position parallel to the lower heat plate 12 is adjusted. A contact member 26 perpendicular to the side frames 21 is fixed to the side of the lower heating plate 12 from the vicinity of the front ends of the side frames 21a and 21b.
6 contacts the front side peripheral member of the lower heating plate 12 in a state where the support frame 24 is pulled down on the lower griddle 10,
And the lower heating plate 12 are held in parallel with each other.

The hook 23a of the cross frame 23 is formed so as to project in a state in which the upper griddle 20 is pulled down on the lower griddle 10 while being inclined slightly rearward from the vertical direction, and the tip of the hook 23a is pivoted. Possible links 3
1 is connected to a drive mechanism 30 provided on the back surface of the double-sided pottery cooker body 11.

The link 31 is pivotally connected to the hook 23a at its upper end and pivotally connected to the moving plate 32 at its lower end, and the moving plate 32 is further connected to the piston shaft 33a of the hydraulic cylinder 33. Are connected. The moving plate 32 is slidably held at both ends by a rail member 34 arranged in the vertical direction, and the rail member 34 has an upper portion thereof to immobilize a cylinder 33b of a hydraulic cylinder 33. Since it is held, the moving plate 3 moves in accordance with expansion and contraction of the piston shaft 33a.
2 moves vertically along the rail member 34.

As shown in FIG. 5, each of the hydraulic cylinders 33 has a hydraulic cylinder 33R corresponding to the right front upper griddle 20b and a hydraulic cylinder 33L corresponding to the front left upper griddle 20a, and is driven by a motor M. The pressure oil supplied from the hydraulic pump P via the in-line check valve CV is supplied to the four electromagnetic solenoid valves SV1.
From SV4, the oil is supplied to and discharged from the respective oil chambers of the hydraulic cylinders 33L and 33R, and the piston shaft 33a is expanded and contracted. Here, each electromagnetic solenoid valve SV1
SV4 has an electromagnetic solenoid S (SL1 to SL4, SR1
Up to SR4), each electromagnetic solenoid S changes its position by moving the valve toward the center when the exciting coil is energized. In addition, for supplying and discharging pressure oil to and from the oil chambers of the hydraulic cylinders 33L and 33R, it is necessary to connect one chamber to the hydraulic line on the high pressure side and the other chamber to communicate with the hydraulic line on the low pressure side. Electromagnetic solenoid SL
Combination of 1, SL4 and electromagnetic solenoid SL2, SL
The combination 3 and the combination of the electromagnetic solenoids SR1 and SR4 and the combination of the electromagnetic solenoids SR2 and SR3 are energized.

In addition to the above, in the hydraulic circuit, a relief valve RV interposed between a high pressure side hydraulic line and a low pressure side hydraulic line, and a pressure gauge PM for measuring the high pressure side hydraulic pressure are provided.
And a cock C that connects the oil chambers of the hydraulic cylinders 33 to each other.

The energization of the exciting coil in the electromagnetic solenoid S is controlled by the sequence circuit 40 shown in FIG. 6, and the sequence circuit 40 is connected to the commercial AC power source via the main power source switch 41. , PW
2, an up switch URSW and a down switch DRSW as operation switches arranged on the gripping handle 22 of the upper griddle 20a, and an up switch ULSW as an operation switch arranged on the gripping handle 22 of the upper griddle 20b. And down switch DLSW, and timer switch TL
The electric power is supplied to the motor M and the electromagnetic solenoid S from the power supply paths PW1 and PW2 in accordance with SW and TRSW to control the supply and discharge of hydraulic pressure to the hydraulic cylinders 33L and 33R.

Each of the up switches URSW, ULSW and the down switches DRSW, DLSW is composed of a self-reset type push button switch protruding toward the inner surface side with respect to the support frame 24 of the gripping handle 22, and a timer (not shown). The switches TRSW and RLSW are arranged on the front side of the double-sided pottery cooker body 11.

Next, the operation of this embodiment having the above configuration will be described. Initially, the main power switch 41 is turned off, and the upper griddles 20a and 20b are pulled down to face the lower griddle 10. In this state, it is assumed that the upper griddles 20a and 20b are raised upward to burn the hamburger.

First, in order to raise the right upper griddle 20a, the cook presses the up switch URSW while holding the gripping handle 22 on the front side of the upper griddle 20a. Then, as shown in FIG. 6, the connection position of the switching contact in the up switch URSW changes to energize the exciting coil of the relay MR1 and energize the exciting coils of the electromagnetic solenoids SR2 and SR3.

As a result, in the relay MR1, the make contact MR1-1 of the relay MR1 becomes conductive and the motor M starts to rotate, and the electromagnetic solenoid SR2 moves the electromagnetic solenoid valve SV3 to the left in FIG.
The electromagnetic solenoid SR3 moves the electromagnetic solenoid valve SV4 to the right in the figure. Therefore, the oil chamber on the right side of the hydraulic cylinder 33R in the figure is connected to the hydraulic line on the high pressure side, the oil chamber on the left side in the figure is connected to the hydraulic line on the low pressure side, and the piston shaft 33a thereof begins to extend.

The other end of the piston shaft 33a of the hydraulic cylinder 33R is connected to the moving plate 32, and the moving plate 32 moves downward as the piston shaft 33a extends. A link 31 is connected to the moving plate 32, and the other end of the link 31 is pivotally connected to the end of the hook 23a. Therefore, when the moving plate 32 moves downward, the link 31 also moves downward, and the hook 23a rotates clockwise in FIG.

Since the hooks 23a rotate the cross frame 23 clockwise around the support shaft 13, the support frame 24 connected to the cross frame 23 rotates clockwise around the support shaft 13. Move,
The upper griddle 20a supported by the support frame 24 is gradually separated from the lower heating plate 12 and caused.

On the other hand, when the cook is on the left upper griddle 20a
When the grip handle 22 on the front surface of the relay is held and the up switch ULSW is pressed, the exciting coil of the relay ML1 is energized and the exciting coils of the electromagnetic solenoids SL2, SL3 are energized. Then, similarly, the piston shaft 33a in the hydraulic cylinder 33L extends and the upper griddle 20b is caused.

Once both upper griddles 20a, 20b have been raised, the cook is in the lower hot plate 1 of the lower griddle 10.
A hamburger having a predetermined thickness is placed on the table 2, and after placing a required amount, the cooker presses the down switch DRSW so as to grasp the grasping handle 22 on the front side of the upper griddle 20a on the right side. Then, as shown in FIG. 6, the connection position of the switching contact in the down switch DRSW changes to energize the exciting coil of the relay MR2 and energize the exciting coils of the electromagnetic solenoids SR1 and SR4.

As a result, in the relay MR2, the make contact MR2-1 of the relay MR2 becomes conductive and the motor M starts to rotate, and the electromagnetic solenoid SR1 moves the electromagnetic solenoid valve SV3 to the right in FIG.
The electromagnetic solenoid SR4 moves the electromagnetic solenoid valve SV4 to the left in the figure. Therefore, the oil chambers on the left and right sides of the hydraulic cylinder 33R in the drawing are connected to the high pressure side hydraulic line, and the oil chambers on the right side in the drawing are connected to the low pressure side hydraulic line, and the piston shaft 33a thereof begins to contract.

As the piston shaft 33a of the hydraulic cylinder 33R contracts, the moving plate 32 begins to move upward,
The hook 23a is rotated counterclockwise in FIG. 1 via the link 31 connected to the moving plate 32. Then, the hook 23a rotates the cross frame 23 counterclockwise around the support shaft 13, so that the support frame 24 connected to the cross frame 23 moves counterclockwise around the support shaft 13. The upper griddle 20a which is rotated and supported by the support frame 24 is gradually approached toward the lower heating plate 12 and is pulled down.

While the upper griddle 20a approaches the lower hot plate 12 in this manner, the cook holds the gripping handle 22, so that his / her finger or hand can hold the upper griddle 20a and the lower hot plate. It will be held at a position apart from between 12 and 12, and safety is secured.

The upper griddle 20a on the right side is the lower heating plate 12.
Once moved up, do the same with the left upper griddle 20
b is also moved onto the lower heating plate 12.

Of course, in this state, the lower heating plate 12 and the upper heating plate 25 are heated, and the hamburger is simultaneously baked from both sides between them. On the other hand, when the cooking is started in this manner, the cooks use their respective timer switches TRS.
Turn on W and TLSW.

When the timer switch TRSW is turned on, the timer TR1 is energized and the timer TR1 starts counting time.
The time measured by the timer TR1 is preset to the baking time of the hamburger. When the timer TR1 measures the baking time and the same time is completed, the timed make contact TR-1 is turned on for a few seconds.

When the simultaneous limit make contact TR-1 is made conductive, the buzzer BZ1 and the relay RR1 are energized, the buzzer BZ1 makes a sound to inform the cooker that the baking is completed, and the relay RR1 makes the make contact RR1-1 conductive. Excuse me. The make contact point RR1-1 constitutes a self-holding circuit of the relay RR2, and when the make contact point RR1-1 becomes conductive, the make contact point RR1-1 becomes a time break contact point TR2-1 of the timer TR2 via the up switch URSW and the down switch DRSW. Series circuit consisting of exciting coil of relay RR2 and timer TR
Energize 2.

The timed make contact TR-1 of the timer TR1 for measuring the baking time becomes non-conducting after a few seconds, and the make contact RR-1 of the relay RR1 becomes non-conducting as well. Make contact RR-
Make contact RR2 of relay RR2 connected in parallel with 1
-1 is conducting. Therefore, even if the make contact RR-1 becomes non-conducting, the relay RR2 is in the ON state and holds itself.

On the other hand, another make contact RR of the relay RR2
Since 2-2 is also conductive, it is in the same state as when the up switch URSW is turned on, and the relay MR1 and the electromagnetic solenoids SR2 and SR3 are energized. While these are energized, the upper griddle 20a is gradually caused by the action of the hydraulic cylinder 33R as described above.

The timer TR2 is energized together with the exciting coil of the relay RR2.
Energizes the above-mentioned relay MR1 and the like and the upper griddle 20a
To measure the time it takes to trigger
When this time elapses, a timed break contact T for a predetermined time
R2-1 is made non-conductive. Timed break contact TR2-1
Is interposed in the power supply path to the relay RR2,
When the simultaneous break contact TR2-1 becomes non-conductive, the relay RR2 is turned off and the self-holding state is released. Therefore, the make contact RR2-1 of the relay RR2 also becomes non-conductive, and the raising operation of the upper griddle 20a also stops.

The same applies to the left upper griddle 20b. When the timer switch TLSW is turned on, the timer TL1 starts counting the baking time, and when the baking time is completed, the relay RL2 is kept in the ON state.
The self-holding state is maintained only for a predetermined time measured by the timer TL2, and the make contact RL2-2 of the relay RL2 connected in parallel with the up switch ULSW is made conductive.

As a result, the upper griddle 20b is automatically triggered after the completion of baking.

In the above-described embodiment, the drive mechanism 30 is composed of a hydraulic circuit, but the drive mechanism 30 may be composed of a gear mechanism using an electric motor as a drive source. As for the operation switch, a self-return type push button switch is arranged toward the inside of the grip handle 22, but the switch is turned on only when the grip handle 22 is put on a hand. However, other switches such as touch switches can also be used.

The heat source of the lower heating plate 12 and the upper heating plate 25 is not limited to the electric heater, but gas or the like may be used.
