Description

Control method and control structure of gas stove for restaurant equipped with a plurality of burners {controll system and method of plural-bunner-installed gas range for restaurant}

The present invention is a gas range equipped with a plurality of burners, in particular an electronic control unit for controlling a plurality of burners individually, a solenoid valve for supplying gas to the burner step by step and manual ignition and extinguishable by manual operation in case of power failure By opening and closing the valve, it is easier to operate the gas range and the manufacturing cost can be significantly reduced. In the event of a power failure or an opening / closing valve failure, it can be continuously used by a manual valve. It relates to a gas stove for a restaurant having a.

A common gas range is to cook various foods on top of a plurality of divided burners by using liquefied petroleum gas (LP Gas) or liquefied natural gas (LN Gas) as fuel.

Such a gas range is conventionally provided with a cock for supplying fuel, ie gas, to each of the burners described above, and a manual rotary knob for adjusting the gas supply amount by the gas cock.

In addition, the above-mentioned gas range is a domestic gas range having two or four conventional craters, while a gas range used in restaurants typically use 10 or 20 or more bulbs, so a large gas range is used. Various foods will be cooked quickly and in large quantities.

However, in the conventional gas stove described above, in a large restaurant where many food containers are to be cooked at once or a large number of guests are processed at once, a cooking range of a gas range for cooking food, for example, a gas in which more than 10 burners are formed. In the case of using a range, it is difficult for the cook to control the strength and cooking time of the food container placed on each crater.

In particular, according to the type of food to be cooked, the strength of the thermal power must be adjusted step by step, and when cooking time of foods cooked in each crater is different while cooking several foods at the same time, each crater is controlled individually. In this case, in large cases, the labor cost of the cook is also high in the case of a large restaurant because it is necessary to prepare food by attaching people to the crater.

On the other hand, the adjustment of the strength and time of the thermal power in the cooking of food is an important factor controlling the food taste, so in the case of restaurants is a very important problem for management.

Therefore, as in Patent Registration No. 290016 introduced in Korea, a plurality of combustion ports and gas burners installed at the centers of the combustion burners, an igniter for igniting the gas emitted from the gas burners, and gas pipes connected to the respective gas burners are provided. In the gas range comprising a valve for controlling the flow of gas, the gas pipe connected to the gas burner is composed of a strong fire gas pipe for supplying a relatively large amount of gas and a weak fire gas pipe for supplying a relatively small amount of gas, The strong and weak fire gas pipes are connected to the gas burner through a nozzle block having a nozzle tip, and each of these strong and low fire gas pipes is provided with an electronic solenoid on-off valve for controlling the flow of gas. Each gas burner is equipped with a temperature sensing rod for detecting the ignition state. Automatic gas range and its gas with a plurality of cooking ports and burners connected to the air temperature control rod and the gas open / close valve and connected to the electronic control unit to selectively turn on / off the strong and weak fire gas pipes according to the set time. Range control method has been devised.

In addition, the gas range is provided with a separate combustion port and the container support to form a fire tray tray to concentrate the flame to the container, or to receive the soup overflowing from the container.

However, the above-described automatic gas range has a problem in that the automatic gas range cannot be used in case of breakdown, power failure or power failure of the main circuit due to the control of the cooking apparatus by the automatic operation.

That is, due to the characteristics of the microwave oven, which generates high heat, the automatic gas range due to the electrical connection structure frequently causes a failure in the control unit. In this case, since a separate means for manually controlling the cooking apparatus is not provided, During a power outage, the entire gas range will not be available.

In addition, the automatic gas cooker can be cooked only by a constant fire power (strong and weak fire), so it is not possible to handle various menus due to the characteristics of traditional foods that need to be cooked by various fire power, and to cook foods other than the menu. If there is a problem that can not use the gas range. In other words, there is a disadvantage that can handle only a few foods that can be cooked only by a predetermined firepower.

In addition, the configuration for concentrating the flame to the container is to reduce the oxygen supply to reduce the heat supply, and because it does not heat enough to the top of the container, while the food inside the container is not cooked at the same time from the bottom to the top Since it is gradually heated and cooked, it causes a decrease in the taste of the food.

In addition, the configuration of the means for adjusting the weak and strong fire and the means for receiving the soup overflowing to the top of the container is very complicated and composed of a plurality of components, the manufacturing process is very complicated, but the manufacturing cost is very high will be.

The present invention has been made to eliminate the above problems, an electronic control unit for arranging a plurality of burners in a step-by-step cascade and individually controlling a plurality of burners, and supplying gas to the burner step by step By separately installing solenoid valve and manual opening and closing which can be ignited and extinguished by manual operation in case of power failure,

The operation of the gas range is easier, but the manufacturing cost can be significantly reduced, and a large number of cooking vessels can be simultaneously cooked according to the automatic operation, and the switch can be manually operated only according to the needs of the cooker. The present invention provides a control method and a control structure of a gas stove for a restaurant equipped with a plurality of burners, which can be used, and can be continuously used by a manual valve in the event of a power failure or an open / close valve. There is a purpose.

First, looking at the control method according to the operation of the gas range according to the present invention,

It can be selectively used by dividing into automatic operation step by input unit and manual operation step by rotary knob,

In the automatic operation step, the control unit proceeds to the ignition stage, the strong fire stage for the set time, the weak fire stage for the set time, the fire extinguishing stage, the end display stage by the control unit,

The manual operation step includes a first switching step of canceling and turning off the automatic operation step simultaneously with the rotation of the rotary knob, a gas supply step of supplying gas from the gas cock according to the rotation of the rotary knob, and ignition by the igniter simultaneously with the gas supply. The step, the cooking step by the thermal power control by the rotary knob, the fire extinguishing step by the reverse rotation of the rotary knob after cooking, the second switching step of supplying power to the automatic operation step at the same time with the fire extinguishing proceeds sequentially.

In addition, the control structure of the gas range by the control method described above,

A plurality of craters 2, 2 'are formed on the upper part of the main body 1, and a control unit (1) in which burners 3 and 3' in the crater 2, 2 'are formed on one side of the main body 1; 4) In the gas range equipped with a plurality of burners that can be controlled automatically by (4 '),

The upper part of the main body 1 is formed stepwise back and forth by the step 5, the rear side of the main body 1 protrudes the frying prevention jaw 6 in the upper part,

Known soup holders 7 and 7 'are placed in the above-described craters 2 and 2', and the gas supplied to the burner 3 and 3 'which is discharged is branched from the main supply pipe 8. To be provided by the automatic supply pipe (9) and the manual supply pipe (10), respectively,

In the automatic supply pipe (9), the gas switch 11 by the solenoid valve and the gas amount regulator 12 by another solenoid valve are formed continuously,

The manual supply pipe 10 is coupled to a known valve cock 14 having a rotary knob 13,

The gas is supplied to the burners 3 and 3 'through the automatic supply pipe 9 by the time and the thermal power designated by the controllers 4 and 4'.

By rotating the rotary knob 13 is configured to enable the use of automatic or manual selective gas range to supply gas to the burners (3) (3 ') through the manual supply pipe (10).

In addition, the above-described gas amount regulator 12 uses a conventional solenoid valve, and is seated on the seat hole 18 in which the opening / closing rod 17 which is lifted by the power supply of the coil 16 in the valve body 15 is seated. As a separate cut groove 19 is formed, the amount of gas to be distributed in accordance with the lifting and lowering of the opening and closing bar 17 is adjusted.

In addition, the electric rotary switch 13 is provided with a gas switch 11 and the switch 20 for supplying power to the gas regulator 12, the electric switch 11 and the gas switch 11 at the same time as the rotary knob 13 is rotated. By configuring the power supply to the gas volume controller 12) and thereby, the automatic supply pipe (9) is automatically closed when switching manually.

In addition, a separate adjustment hole 29 is further formed on the side of the seat hole 18 of the above-described gas amount regulator 12, and the adjustment hole 30 having an inclined surface for opening and closing the adjustment hole 29 is coupled to the b. The four bars 32 may be screwed to the threaded holes 31 formed on the side surfaces of the valve body 15 so that the jaws 29 may be gradually opened and closed by the rotation of the threaded rods 32.

In the drawings, reference numerals 21, 21 'are vents, 22 is a soup bowl, 23 is an igniter, 24 is an ignition detector, 25 is a display unit, 26 is a control unit, 27 is an input unit, and 28 is a power switch.

The operation of the gas range according to the present invention having the above configuration will be described in more detail with reference to the accompanying drawings.

First, in the gas range according to the present invention, the heights of the predetermined number of craters 2, 2 'and the burners 3, 3' are different from each other by the step 5 formed in the upper portion of the main body 1. By doing so, when a plurality of cooking vessels are arranged in succession, the handling of cooking vessels on the rear side is improved by the fact that the cooking vessels, etc. are not easily put in by the cooking vessels on the front side.

The frying prevention jaw 6 formed at the rear upper end of the main body 1 has a broth boiled and splashed or flowed from the container placed on the broth holders 7 and 7 'of the rear crater 2, 2'. It is intended to prevent the wall from becoming dirty by flowing to the rear side of 1) or by bouncing on the interior wall.

Further, as is well known, the soup tray 22 inserted into and detachably inserted into the lower side of the main body 1 includes various soups and food dregs which are poured into the bottom of the soup tray 7 and 7 '. Falling to the soup bowl 22 is to be collected at a time as the cause of the formation of the kitchen cleanliness.

This schematic gas range is a plurality of burners (3) (3 ') in the plan view as shown in Figure 2 is a continuous formation at regular intervals,

Each burner (3) 3 'is connected by an automatic supply pipe (9) and a manual supply pipe (10) from a main supply pipe (8) for supplying gas to each burner (3) (3') inside the main body (1). It can be seen that it is formed.

Here, the electrical supply pipe 9 is a gas switch 11 and the gas volume regulator 12 is coupled to the middle portion of the tube, the gas switch 11 to control the communication or blocking of gas, In the gas amount regulator 12, the amount of gas communicated is controlled. By mounting a conventional solenoid valve, the gas amount regulator 12 is operated while the gas switch 11 is opened to burner (3) (3 '). By controlling the amount of gas supplied to the power of the thermal power is controlled.

In addition, the manual feed pipe 10 as described above allows gas to be supplied to the burners 3 and 3 'via the valve cock 14 to which the rotary knob 13 exposed to the outside of the main body 1 is coupled. ,

When the rotary knob 13 is rotated while the gas switch 11 is closed, the gas is supplied from the main supply pipe 8 through the valve cock 14 to supply the gas to the burners 3 and 3 '. Therefore, the ignition is made.

In addition, the valve cock 14 described above is known, and since the amount of gas communicated according to the amount of rotation of the rotary knob 13 is determined, the amount of rotation of the rotary knob 13 rotated by the cooker is determined from the crater. The intensity of firepower generated is determined.

The gas range of the present invention is that the path and the action step of the gas by the automatic and manual operation as shown in Figure 4 is completely different,

First, referring to the automatic operation step, when power is applied by the power switch 28, the power is applied to each part.

After inputting a desired menu or time to the input unit 27 formed on one side of the main body 1 in the state of applying the power, when the start button is pressed, the control unit 26 recognizes the start signal and the igniter 23. To burn the burner (3) (3 ').

At this time, the gas supplied from the main supply pipe 8 at the same time as the start signal of the input unit 27 is supplied to the burners 3 and 3 'through the gas switch 11 and the gas amount regulator 12 formed in the automatic supply pipe 9. Therefore, the burners 3 and 3 'are ignited by the ignition attempt of the igniter 23.

After the ignition step, the food is continuously cooked in a strong fire state by the time specified by the input unit 27, and after a certain time, the gas volume controller 12 is operated to be in a low fire state.

This weak fire state is applied when the moxibustion of various foods or when heated to a low heat, the gas volume controller 12 receives a signal from the control unit 26 to adjust the amount of gas communicated to the low fire state It is.

After the predetermined period of time, such a weak payment stage, the gas switch 11 is operated by the control unit 26 again to cut off the supply of gas, so that the burners 3 and 3 'are automatically extinguished.

In addition, as the burner is extinguished as described above, the separate display unit 25 generates a flashing lamp or a buzzer sound through the speaker, thereby allowing the cook to recognize the cooking completion state more easily.

When the ignition detector 24 does not ignite due to unstable operation of the igniter 23 while gas is being supplied, the ignition detector 24 sends a signal to the control unit 26 to perform continuous ignition attempts by the igniter 23. It is to make it.

Since the configuration of the display portion 25 and the ignition detector 24 has the same purpose as that of the conventional art, more detailed description thereof will be omitted.

Here, the operation relationship between the gas switch 11 and the gas amount regulator 12 is described in detail by the illustration of Figure 5a and 5c,

As shown in FIG. 5A, in a state in which both the gas switch 11 and the gas amount regulator 12 are closed, the gas supplied is not communicated, and thus the gas fire is extinguished. As shown in FIG. 5B, the gas switch 11 is illustrated. When the power is applied to the coil 16 of the) and the opening rod 17 is raised, a gap is generated between the opening rod 17 and the seat hole 18, so that the gas is communicated through the gap.

As such, the gas communicated through the gas switch 11 reaches the gas volume controller 12 and its traffic is controlled. As shown in the drawing, the opening and closing rod 17 of the gas volume controller 12 is lowered. And gas is communicated only through the cutout groove 19 formed between the sheet hole 18 and the sheet hole 18 so that the amount of gas communicated is relatively small, so that the gas fire is ignited in a weak state.

In addition, as shown in FIG. 5C, when power is applied to both the gas switch 11 and the gas amount regulator 12 so that all the opening and closing rods 17 are raised, the inside of the valve is opened so that the amount of gas communicated is maximum. The gas fire is ignited in a strong fire state.

Therefore, by the organic operation of the gas switch 11 and the gas amount regulator 12 will be responsible for the fire or weak fire of the gas fire as well as the fire extinguishing function.

In addition, in the ignition process by the aforementioned weak fire, as shown in the other embodiments of FIGS. 7 and 8, another adjustment hole 29 is further formed on the side of the seat hole 18 in which the opening and closing rod 17 in the valve is seated. The screw rod 32 capable of gradually opening and closing the adjusting hole 29 is screwed to the valve body 15, and the screw rod 32 screwed to the screw hole 31 of the valve body 15. The adjustment hole 29 is gradually opened and closed by the jaws 30 of the inclined surface formed at the end of the screw rod 32 by rotation.

Therefore, when the screw rod 32 is fully advanced and the adjusting hole 30 completely closes the adjusting hole 29, the gas flows only through the cutout groove 19 of the seat hole 18, so that the gas is in the least weak state. Will be

When the screw rod 32 is artificially rotated, gas is also distributed through the adjusting hole 29 at the same time, so that a larger amount of gas is supplied to maintain a relatively strong weak fire.

Therefore, the cooker can arbitrarily adjust the intensity of the weak fire according to the characteristics of the food, which enables the cooking of various foods, as well as the intensity of the most suitable state.

The above automatic operation step can be cooked only at a predetermined time and firepower, so it is very fast and convenient to cook a limited menu, but it is not applicable to foods that need to adjust the fire power at the moment while requiring various firepower. In order to switch to the manual operation stage to arbitrarily adjust the strength of the fire and to be the most suitable cooking example,

In the manual driving step, as shown in FIG. 6, the switch 20 that is in contact with the rotary knob 13 reacts with the rotation of the rotary knob 13, and the reaction of the switch 20 is performed by the gas switch. (11) and by the first switching step of automatically shutting off the power applied to the gas amount regulator 12 is automatically switched to the manual operation step.

As described above, when gas flows into the manual feed pipe 10 from the main feed pipe 8 at the same time as the rotary knob 13 rotates, the valve cock 14 moves the gas to the burner 3, 3 'side. The amount of gas delivered is to be proportional to the amount of rotation of the rotary knob 13.

In addition, when the rotary knob 13 is rotated for a predetermined period or more, the burner 3 and 3 'are ignited by the igniter 23 automatically by the conventional configuration and method.

Therefore, since the intensity of the thermal power can be arbitrarily changed according to the rotation amount of the rotary knob 13, the cooking can be performed by an arbitrary operation as in the prior art, so that various and detailed cooking is possible.

In addition, after the cooking by the manual operation as described above is finished, if the rotary knob 13 is reversed again so that the switch 20 is operated by the rotary knob 13, the switch 20 is sensitive. The control unit 26 recognizes the signal and proceeds to the second switching step in which the automatic driving means is switched to the ready state in the state where the temporary power is applied.

Hereinafter, a cooking example will be described as an example of the operation method of the gas range according to the present invention.

First, as an example of cooking by automatic operation, the cooker turns on the power switch 28 of the gas range and selects a menu to be cooked in a preset order by operating the input unit of the burner.

In addition, as described above, the selected menu is a preset heating time of the strong and weak fires most suitable for the food.

As described above, when the selection of the menu is made, the start button is pressed, and the fire is ignited at the same time as the start button is operated, and the fire is raised to the fireball.

Therefore, when the food is heated by a strong fire, a predetermined time elapses and then automatically switches to a low fire and undergoes a cooking process such as moxibustion or broth.

In addition, even the above-described weak fire process is terminated by the passage of time to automatically extinguish the burner by cutting off the supply of gas.

The input unit may be combined with a variety of functions, that is, a timer selection switch for specifying and adjusting the heating time of the preselectable menu and the liquid fire, and after the cooking is finished, You can also indicate this.

Since the ignition time of the crater designated by the ordinary reservation circuit is reserved in advance, it may be configured to enable more convenient cooking.

In addition, when the fire is extinguished by the ignition failure and the overflow of the soup during cooking, it is possible to change the design of the control unit to automatically detect the detection and re-ignition with a warning sound.

In addition, the cooking example by manual operation simply rotates only the rotary knob 13 as in the conventional gas stove operating method, so that the ignition and fire control as well as the function of fire extinguishing can be performed in parallel. And time can be set to the cooker arbitrary.

Therefore, as described above, the cooking time and the power of the firepower can be used to simultaneously heat and control a plurality of cooking vessels, and if necessary, the desired cooking tools and burners can be manually switched to cook individual menus and food. You can do it.

As described above, the control method and the control structure of a gas stove for a restaurant equipped with a plurality of burners are easier to operate the gas range and can significantly reduce the production cost thereof. The container can be cooked at the same time, and the switch can be used to manually operate only the necessary crater according to the cooker's needs.In the event of a power failure or an opening / closing valve failure, it can be continuously used by a manual valve, which greatly increases the efficiency. There is an improved effect.
