Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker used for boiling and steaming, for example.

[0002]

2. Description of the Related Art As a cooking machine of this type, for example, a boiling noodle machine for business use, a heating source such as a heater is arranged corresponding to each of a plurality of heating tanks provided in a sink, and each heating source is arranged. Is known to heat and boil the hot water in the corresponding hot water tank.

When cooking boiled noodles using such a boiled noodle machine, a cook immerses a noodle basket called Tebo containing raw noodles, which is a food ingredient, in the boiling water in a water bath, When the noodles have boiled, the noodle basket is pulled up from the bath and the ingredients are transferred to a bowl or the like. Further, when boiling the noodles, the heating output of the heating source is set to a maximum.

[0004]

By the way, since the conventional boiled noodle cooking machine has a structure in which the control of the heating output by the heating source depends on human operation, the noodles are boiled and the noodle basket is removed from the bath. It is extremely troublesome for the cook to operate the output adjustment knob of the heater to reduce the output of the heating source each time it is pulled up, and even if the noodles are not boiled, the heating source should be heated to the maximum. It is customary to leave it in the output state. For this reason, there is much waste such as electricity consumption for heating the hot water in the hot water tank, and the running cost is high.

Particularly in a commercial boiling noodle cooking machine having a plurality of hot water tanks, the situation in which a plurality of hot water tanks are properly used according to the number of orders of the customer continues, so that the cook pulls up the noodle basket from the hot water tank. In addition, the heater and the like corresponding to the hot water tank when not in use are rarely closed, and the waste of the gas fuel is great.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a heating cooker capable of suppressing running costs by automatically adjusting the heating output when the heating tank is not used.

[0007]

[Means for Solving the Problems] The above-mentioned problems are solved by a heating tank installed in a cooker main body, a heating means for heating a heating medium in the heating tank, and cooking in a heating tank containing food ingredients. The cooking container used and arranged above the heating tank,
A container mounting member that detachably holds the cooking container, and a container mounting member that supports the container mounting member, and the cooking container is mounted on the container mounting member. Container elevating and lowering drive means for descending to a predetermined cooking position, and ascending and cooking of the food at the predetermined cooking position through the container mounting member to a predetermined standby position on the heating tank. Heating output adjusting means for increasing the heating output by the heating means when the cooking container is lowered to the predetermined cooking position, and decreasing the heating output by the heating means when the cooking container is moved up to the predetermined standby position. And a heating cooker characterized in that

In this heating cooker, when a cooking container containing food is placed on the container placing member, the cooking container is moved up and down through the container holding member to move the cooking container to a predetermined cooking position in the heating tank. When the cooking container is lowered to the predetermined cooking position while the cooking container is immersed in the heating medium in the heating tank, the heating output of the heating device is automatically adjusted by the heating output adjusting device. And the food is cooked properly.

On the other hand, when the cooking of the food is completed, the container elevating and lowering means automatically lifts the cooking container together with the container mounting member from the heating tank and ascends to a predetermined standby position. At this time, the heating output of the heating means is automatically reduced by the heating output adjusting means. Therefore, the thermal energy related to heating is saved, and the running cost can be significantly reduced.

Further, the container elevating / lowering drive means supports a slide structure which is vertically movable with respect to the main body of the cooking machine, and supports the container mounting member so as to be axially held by the slide structure. And a motor that rotates by receiving the output of a detection rod that detects that the cooking container is placed on the container placement member by an axial displacement and a position detector that detects the axial displacement of the detection rod. And a reciprocating mechanism that converts the rotation of the motor into a linear motion and transmits the linear motion to the slide structure.
A heating output operation member of the heating means, and a cam member that converts the slide displacement force into an operation force of the heating output operation member and transmits the sliding displacement force when the slide structure slides vertically. It may be configured.

In this case, since the container elevating and lowering driving means and the heating output adjusting means can be constituted by substantially mechanical parts, electrical failure due to moisture, dirt and the like is unlikely to occur.

Further, the heating means is composed of a gas burner arranged below the heating tank, and a partition wall for directing combustion gas from the gas burner to the outer surface of the peripheral wall of the heating tank is arranged so as to surround the heating tank. A fin may be provided on the outer surface of the peripheral wall of the heating tank so as to face the combustion gas passage between the tank and the partition wall.

In this case, the partition wall prevents the flame and the combustion gas from the gas burner from escaping to the outside of the heating tank, while the fins contact the combustion gas, so that the heating efficiency is improved.

When the noodle basket 2 is placed, the container placing member 3 is pivotally moved counterclockwise in FIG. 7 with the upper end opening edge 65c of the tube body 65 as a fulcrum, and is moved to the detection rod 66. On the other hand, an upward displacement force is generated.

In the lower part of the tube body 65, the tube body 65
Together with the slider structure 60, a plate-shaped slider 64
The upper end 64a of the is connected and fixed. This slider 6
4, the limit switch 67 is attached, and the upward displacement of the detection rod 66 is detected to detect the motor 6
It is designed to activate 2.

Inside the upper end 65a of the tube 65,
As shown in FIG. 7, an annular upper spring seat 101 is fixed. Further, the male screw portion 102 formed on the outer peripheral surface of the upper end portion 66a of the detection rod 66 has a lower spring seat 103 at the lower end and a female screw portion 104 formed on the inner peripheral surface thereof. The screw body 69 is screwed.

The lower spring seat 103 is displaced in the vertical direction by screwing, and the spring force of the coil spring 68 is adjusted.

By placing the noodle basket 2 on the container placing member 3, the arm portion 32 of the container holding member 3 is moved to the tubular body 6.
Since the upper end opening edge 65c of 5 is used as a fulcrum to rotate in the counterclockwise direction in FIG. 7, the noodle basket 2 is pulled up to the tip of the detection rod 66 via the tip side of the arm portion 32 due to the load. The force will act. As a result, the limit switch 67 performs a detection operation (here, OFF),
In response to this, the motor 62 is started. The rotation shaft 62a of the motor 62 is rotated by 180 ° each time it is started.

By rotating the knob 70 for adjusting the load of the noodle basket, the sensitivity of detecting the placement of the noodle basket according to the weight of the noodle basket 2 can be adjusted. For example, when the weight of the noodle basket 2 is relatively small, the noodle basket 2 is placed on the container placing member 3 by operating the knob 70 to extend the compression length of the coil spring 68 and weaken the spring force. The detection rod 66 when it is opened easily moves axially against the spring force.

Referring to FIG. 6, the base end of a crank lever 71 is fixed to the rotary shaft 62a of the motor 62, while the tip end of the crank lever 71 is reciprocated with the crank lever 71. The lower end of the connecting lever 72 that constitutes the movement mechanism 63 is connected via a pivot 73.

The upper end of the connecting lever 72 is connected to the lower end of the slider 64 via a pivot 74. The reciprocating mechanism 6 is driven by the rotation of the motor 62.
By moving the slider 64 downward by a predetermined amount through the tube 3, the pipe body 65 moves downward together with the detection rod 66, and accordingly, the noodle basket 2 moves down to a predetermined cooking position in the oil tank 4. It is configured.

Below the reciprocating mechanism 63, there is arranged a position sensor 75 for detecting that the tip end side (the pivot 73 side) of the crank lever 71 has rotated 180 ° to the bottom dead center position. With the detection operation of the sensor 75, the rotation of the motor 62 is stopped until a fixed time required for boiling the noodles elapses. This fixed time is arbitrarily set by operating the dial (FIG. 1) 91 for the timer device 90 (FIG. 3) housed in the control box 13a.

The heating output adjusting means 8 includes a cam plate 81 fixed to the slider 64 and a valve drive lever 82 as a heating output operating member driven by the cam plate 81.
It has and.

The cam plate 81 is formed with a cam groove 83 for displacing the vertical displacement force of the slider 64 in the forward / backward operation direction of the plunger 52a of the valve 52.
As shown in FIG. 5, the entire front shape of the cam groove 83 is substantially S-shaped, and the upper side 83 a of the cam groove 83 is located.
Is for guiding the drive lever 82 to the right in FIG. 5 so that the plunger 52a of the valve 52 advances and opens. On the lower side 83b, the plunger 52a of the valve 52 is retracted. It is configured as a guide for pushing the drive lever 82 to the left in FIG. 5 so as to perform the closing operation.

Each of the front panel portions of the left and right long box portions 12, 12 corresponds to the pair of front and rear hot water tanks 4, 4 on the left side.
The timer time setting dial 91 and the timer time display section 92 are provided. The timer time display section 92 also serves as a reset switch when the container mounting member 3 is inadvertently touched to operate the container elevating and lowering drive means 6.

Next, the operation of the boiling noodle machine having the above structure will be described.

Here, the case of using one bath 4 will be described as a representative.

First, when the drain valve 46 is closed and the water supply handle (not shown) is opened, the hot water W taken from the outside and passed through the water supply path 15 is supplied from the faucet 16. The hot water W reaches the sink surface 11a through the hot water supply hole 18 and is supplied into the hot water tank 4 through the opening 11d of the sink surface 11a, so that the hot water W can be filled to a predetermined level in the hot water tank 4. Further, the timer operation dial 91 is operated to set the boiling time of the noodle M at that time. After that, when the pilot burner ignition knob 54 is operated, the pilot burner 53 is ignited and the hot water W in the oil tank 4 is preheated to a predetermined temperature.

When the noodle basket 2 containing the noodles M is fitted into the ring portion 31 of the container placing member 3 at the standby position and placed, the container placing member 3 causes the arm portion 32 to move due to its weight. The upper end opening edge 65c of the pipe body 65 in contact
With the fulcrum as a fulcrum, it turns counterclockwise.

Due to the rotational displacement of the tube body 65 in the counterclockwise direction, the detection rod 66, to which the tip of the arm portion 32 is fixed, is displaced upwards against the downward spring force of the coil spring 68. Limit switch 67 is turned off
Since the placement of the noodle basket is detected, the motor 62 is activated. Of course, when the limit switch 67 is turned on, the motor 62
May be set to start.

As the rotating shaft 62a of the motor 62 rotates, the tip of the crank lever 71 at the top dead center position is shown in FIG.
The slider 64 turns 180 degrees to the bottom dead center position indicated by the chain line, so that the slider 64 moves downward via the connecting lever 72. Due to the descending displacement of the slider 64, the tube body 65 also descends together with the detection rod 66, so that the noodle basket 2 placed on the container placing member 3 has the openings 11c and 11d as shown in FIG. It passes through and descends into the hot water tank 4.

When the crank lever 71 pivots about 180 ° and shifts to the bottom dead center position, the position sensor 75 detects the rotation and the rotation of the motor 62 is stopped, while the timer time corresponding to the boiling time is measured. Be started.

Thus, the noodle basket 2 is placed on the container mounting member 3
When the noodles are placed on the noodle basket 2, the noodle basket 2 automatically descends to the predetermined cooking position in the hot water tank 4, and the noodles M are sufficiently immersed in the hot water W.

On the other hand, as the slider 64 moves downward, the cam plate 81 also moves downward, so that the tip end portion 82a of the valve drive lever 82 engaged with the cam groove 82 of the cam plate 81 is moved to the cam groove. It is guided by the upper side 83a of 83 and pulled rightward as shown in FIG. 5 (B).
Therefore, the valve 5 is connected via the coupling member 55.
The second plunger 52a is pulled, and the open / close valve 52 of the gas burner 5 is opened.

When the opening / closing valve 52 of the gas burner 5 is opened, the gas supplied from the opening / closing valve 52 to the gas burner 5 is ignited and burned by the pilot burner 53, and the hot water W in the hot water tank 4 is heated and boils. Therefore, the noodles M in the noodle basket 2 are boiled. The cook may wait for the elapse of the timer time corresponding to the time until the noodle M is boiled.

Even if the flame or combustion gas generated by the gas burner 5 tries to escape to the outside of the oil tank 4, it is blocked by the partition wall 42 around the hot water tank 4, while the fins 41 swirl along the outer surface of the peripheral wall 4a. Since the temperature rises, the heating efficiency is improved, the boiling of the hot water W is quick, and the noodles are guaranteed to boil well.

After that, when the timer set time elapses, the motor 62 is restarted. Rotating shaft 62 of motor 62
Along with the rotation of a, the tip of the crank lever 71, which is now at the bottom dead center position, is pivotally displaced by 180 ° and returns to the top dead center position shown by the solid line in FIG. 64 goes up. This slider 64
The pipe 65 also rises together with the detection rod 66 due to the upward movement of the noodle basket 2. Therefore, the noodle basket 2 placed on the container placing member 3 also moves upward and is pulled up from the hot water tank 4 through the opening 11c. To be

When the noodle basket 2 is taken out from the container mounting member 3 with the tube 65 raised to the initial standby position together with the detection rod 66, the detection rod 66 causes the coil spring 68 to move.
Since it is lowered by the spring force of, the limit switch 67 is turned on at the lower end of the detection rod 66 and the rotation of the motor 62 is stopped. Note that the motor 62 is stopped by the limit switch 6
It may be configured to automatically stop when the tip of the crank lever 71 returns to the top dead center position without waiting for the turning on of 7.

On the other hand, since the cam plate 81 also moves upward as the slider 64 moves upward, the tip end portion 82a of the valve drive lever 82 engaged with the upper side 83a of the cam groove 82 of the cam plate 81. Is the lower side 8 of the cam groove 83
It is guided by 3b and driven leftward as shown in FIG. Therefore, the plunger 52a of the valve 52 is retracted via the coupling member 55, the opening / closing valve 52 is closed, and a standby state until the next boiled noodle is reached. Combustion of the gas burner 5 is stopped by closing the open / close valve 52.

As described above, when the timer time corresponding to the optimum boiling time elapses, the noodle basket 2 is automatically pulled up from the water bath 4, so that the cooker does not have to worry about how much the noodle M is boiled. However, the properly boiled noodle M can be taken out, and can be directly transferred to the next cooking step.

When the noodle basket 2 is pulled up, the open / close valve 52 of the gas burner 5 is automatically closed. Therefore, even if the cook does not operate the valve 52 every time the noodles are boiled, Fuel gas consumption will be saved.

By the way, the container elevating and lowering driving means 6 and the heating output adjusting means 8 are not limited to the above-mentioned constitutions. The detection rod 66, the crank lever 71, the connecting lever 72 and the like are mechanically configured, while the heating output adjusting means 8 is provided with the coupling member 55,
By mechanically configuring the cam plate 81, the drive lever 82, etc., there is an advantage that the occurrence of a failure due to moisture such as steam or dirt can be avoided as much as possible. However, in this invention,
It does not prevent using an electromagnetic valve as the opening / closing valve 52 and the like.

The heating means 5 is not limited to the one using a gas burner, but a heater can be used to obtain the same effect.

Further, although the pilot burner 53 is always ignited and the combustion output of the gas burner 5 is controlled to be turned on and off, the heating output is adjusted, but the combustion of the gas burner 5 is not stopped. It may be configured such that high heat is used when cooking and low heat when not in use. Further, without using the pilot burner 53, the combustion of the gas burner 5 may be set to a high flame when cooking and to a low flame when not in use.

FIG. 8 shows another embodiment of the present invention, and is a perspective view showing the vicinity of the adjacent hot water tanks 4 with the fins 41 on the outer surface of the hot water tank omitted.

In this embodiment, the lower portions of at least two hot water tanks among the plurality of hot water tanks 4 are connected to each other by the communication pipe 4a.
The drainage pipes 44 are not provided at the bottom of each hot water tank 4, but the hot water baths 4 that are communicated with each other are not provided with drainage pipes 44 and those not provided. Existing. In this embodiment, all of the four hot water tanks 4 are communicated with each other by the communication pipes 4a, and the drain pipe 44 is provided only in one hot water tank. Note that the other configurations are the same as those of the embodiment shown in FIGS.

With this structure, the hot water supplied to one hot water tank 4 is also supplied to all the hot water tanks 4 by the communication pipe 4a, and the hot water in each hot water tank 4 can be set to the same amount. Moreover, when the hot water is drained, the hot water in the hot water tank in which the drain pipe 44 is not provided flows through the communication pipe 4a into the hot water tank in which the drain pipe 44 is provided,
Drained from 4. For this reason, the drain pipes 44
Since the length of the path leading to the noodles becomes long, when some of the noodles remain in the hot water tank in which the drainage pipe 44 is not provided, it becomes difficult for the noodles to be discharged from the drainage pipe 44. It is possible to suppress the inconvenience that noodles flow into 44 and become clogged. Moreover, for the hot water tank 4 in which the drainage pipe 44 is not provided, the position and shape of the burner 5 arranged below the drainage pipe 44 can be selected independently of the drainage pipe 44, so the position and shape with the highest heating efficiency can be selected. The overall heating efficiency is improved.

It should be noted that the lower portions of the baths 4 are connected to each other by a communication pipe 4a.
9, the same effect can be obtained even if the hot water tanks are communicated with each other by the communication portion 4b formed over the entire height direction in a part of the circumferential direction of the hot water tanks 4 as shown in FIG. You can

FIG. 10 shows still another embodiment of the present invention. In this embodiment, each hot water tank 4 is formed by partitioning the inside of a large rectangular sink 400 with, for example, a cross-shaped partition 401. A partition wall 42 is formed to surround the sink 400, and the sink 4 is formed on the outer surface of the sink 400.
00 and the partition wall 42, which is a space 48 serving as a flow path for combustion gas.
The fin 41 is formed to face. In addition, below each of the hot water tanks 4, the burners 5 are respectively arranged as in the above-described embodiment. With such a configuration, the heating efficiency can be increased.

In this case, it is desirable that the space for disposing the burner 5 be also divided for each hot water tank from the viewpoint of preventing the thermal influence of the combustion gas of the adjacent burner. Further, in order to prevent the heat transfer from the adjacent hot water tank 4 as much as possible to prevent the thermal effect of the adjacent hot water tank 4 and to realize independent heating control for each hot water tank, a partition 401 for partitioning each hot water tank is provided. It is desirable that the partition for partitioning the space for arranging each burner is made of a heat insulating material.

According to the first aspect of the present invention, when the cooking container containing the food is placed on the container placing member, the cooking container is automatically moved down to the predetermined cooking position in the hot water tank. On the other hand, the heating output is increased, and the heating output is automatically reduced when the food temperature rises and rises with the completion of cooking, so the cooker may intentionally adjust the heating each time he removes the cooking container. Even if it is not necessary, it is possible to suppress the waste of energy for heating, and thus it is possible to reduce the running cost.

According to the second aspect of the present invention, the ascending / descending drive means is composed of the slider structure, the detection rod, the reciprocating mechanism, etc., and the heating output adjusting means is composed of the heating output adjusting member and the cam member. As compared with the case where electric parts are used for the parts in this part, the failure caused by moisture or the like is reduced.

According to the third aspect of the present invention, the gas burner is used as the heating means, and the partition wall for directing the combustion gas from the gas burner to the outer surface of the peripheral wall of the heating tank is provided so as to surround the heating tank. Since the fins are provided on the outer surface of the peripheral wall of the heating tank facing the combustion gas passage between the partition wall and the partition wall, the heating efficiency can be improved.
