Description

Method for controlling table frier}

The present invention relates to a control method of a table fryer which puts water and oil, such as cooking oil, together in a restaurant such as a restaurant or a restaurant, and fry a predetermined food while heating with a heater.

Generally, when cooking fried food, oil such as cooking oil is placed in a frying pan of a predetermined shape, and the food is heated while the frying barrel is heated outside or by heating the oil to a high temperature using an electric heater mounted inside the frying pan. It's supposed to be fried.

At this time, the frying crumb occurs in the process of frying the food in oil, some of the fried crumbs are suspended in the oil layer, and the rest sinks to the bottom of the frying pan. The fried flakes floating in the oil layer can be easily picked up by the user using a strainer. However, the fry crumbs that sank to the bottom of the fry can not be part of the fry even if they are squeezed with a strainer, and will remain. The remaining fried crumbs are excessively fried by high temperature oil and carbonized, resulting in deterioration such as discoloration of the oil, and deterioration of the cooking state of the food according to the deterioration of the oil, as well as frequent oiling. There was a variety of problems, such as the need to replace the oil consumption increases.

Recently, table fryers have been proposed and used using characteristics of oil and water, that is, oil and water are naturally arranged up and down by a difference in specific gravity.

Table fryers using the characteristics of the oil and water, when water and oil are put together in the frying barrel due to the difference in specific gravity, the water is located in the lower portion of the frying barrel, the oil is located in the upper portion.

Therefore, the frying crumbs generated when the food is fried while heating the oil at a high temperature are accumulated in the water at the bottom, and thus the frying flakes accumulated in the water are not carbonized even when the table fryer is used for a long time, thereby preventing the deterioration of the oil.

However, the above-described conventional table fryer immediately supplies power to the heater when the power switch is turned on regardless of the water level, so that the heater generates heat. Therefore, if the water level is high because there is too much water stored in the frying pan, the water is heated by the heat generated by the heater to generate steam, and the generated steam rises to the top to scatter oil, causing safety accidents such as burns. Done. In addition, even if the heater is exposed to the atmosphere due to no water and oil in the frying pan, when the user accidentally turns on the power switch, the heater is supplied with power and generates heat, which causes the heater to overheat and disconnect frequently. It is occurring.

And the table fryers have to wash the frying pan almost every day due to hygiene problems, but in the past, when washing the inside of the greasy frying pan, boiling water was prepared and put in the frying pan, and the user had a lot of inconvenience. In addition, the safety accidents such as burns frequently occurred due to carelessness of the user in the process of putting boiling water into the frying pan and washing.

Accordingly, an object of the present invention is to provide a control method of the table fryer to determine the water level of the water stored in the frying container when the frying is cooked, so that the user can put the water within a predetermined predetermined level in the frying container. .

Another object of the present invention is to provide a control method of the table fryer so that the heater does not generate heat when the water level of the fry box is higher or lower than a predetermined level.

Still another object of the present invention is to provide a control method of a table fryer which can clean the inside of a frying pan by heating the washing water placed in the frying container when the washing mode is selected.

Still another object of the present invention is to set the washing water level at a position higher than the installation position of the heater in the washing mode, and to prevent the heater from being damaged by heating the heater only when the washing water is stored above the set washing water level. It is to provide a control method of the table fryer.

In the control method of the table fryer of the present invention having the above object, it is determined whether the cooking mode or the washing mode is set, and when the cooking mode is set, it is determined whether or not the level of the frying pan is a predetermined level. It determines whether the start switch signal is input when the level of the fryer reaches the set level, and when the start switch signal is input, it judges the set temperature and present temperature of the oil stored in the fryer and The heating of the heater is controlled to be maintained at the set temperature, and when the washing mode is set, the washing temperature is set, the temperature of the washing water stored in the frying pan is judged, and the heating of the heater is maintained so that the determined washing water temperature becomes the set washing temperature. It is characterized by controlling.

In the initial stage of power-on, the table fryer is initially checked and an error is generated to determine whether an error has occurred.

In another aspect, the present invention is to control the heating of the heater to determine the level of the frying tank in the state of maintaining the oil temperature of the frying tank and stops the heater and generates an alarm when the determined water level is above the preset full water level, Before the washing temperature is set in the washing mode, the water level of the frying pan is first detected, and when the detected water level is higher than the preset washing water level, the washing temperature is set and the washing water temperature is determined.

In the control method of the present invention applied to the table fryer 100 having such a configuration, as shown in FIG. 4, the controller 300 is initially supplied with operating power by turning on the power switch 151. In operation 402, the state of each component of the table fryer 100 is initially checked to determine whether an error has occurred in step 404. For example, it is determined whether disconnection or the like of the heater 220 has occurred.

When an error occurs as a result of the determination in step 404, the controller 300 outputs an alarm in step 406, that is, controls the display lamp driver 370 to light up the display lamp 157 indicating an abnormality. In addition, the alarm sound output unit 380 controls the alarm sound to alert the user that there is an abnormality in the table fryer 100, takes a predetermined action, and then returns to the step 402 to perform the initial check. Repeat the operation.

When no error occurs as a result of the determination of step 404, the controller 300 sets the operation mode set according to the operation of the mode selection switch 290 of the command input unit 310 in step 408, that is, a predetermined frying process. It is determined whether the cooking mode for cooking or the washing mode for washing the frying pan 130 is set.

When the cooking mode is set by the mode selection switch 310 as a result of the determination of step 408, the controller 300 determines that the water level detector 330 has a low water level sensor 210 and a full water level sensor 211 in step 410. Determining the current level in the frying pan 130 to detect, and selectively lights up the display lamp 157 of the display lamp drive unit 370 according to the determined current level to the user to raise the level of the frying pan 130 to the appropriate level Make it adjustable. That is, the low water level sensor 210 is installed above the low water level and the low water level sensor 211 is installed to be able to adjust the water level of the frying pan 130 below the high water level.

In the next step 412, the controller 300 determines whether or not the level of water stored in the frying pan 130 is adjusted to the proper level, and when the determination result is not adjusted to the appropriate level, the controller 300 is step 410 Returning to) to determine the current level in the frying pan 130, and selectively lighting the display lamp 157 according to the determined level, and determining whether the level of the frying tub 130 has been adjusted to an appropriate level. Repeat it.

In this state, when the water level of the frying pan 130 is adjusted to an appropriate level, the controller 300 determines whether a signal of the start switch 155 is input from the command input unit 310 in the next step 414, When the signal of the start switch 155 is not input, the process returns to the step 410 to determine whether the level of the frying pan 130 is adjusted to an appropriate level, and starts when the level is adjusted to an appropriate level. The operation of determining whether or not a signal of the switch 155 is input is repeatedly performed.

That is, the user puts water into the frying pan 130, the water level does not stop after reaching the low water level position where the low water level sensor 210 is installed, the water level can be more than the high water level installed by the high water level sensor 211. Therefore, in the present invention, even when the water level is higher than the low water level in the fry container 130, the water level is lower than the full water level, the start switch 155 when the water level is continuously detected until the signal of the start switch 155 is input. Receive the signal of).

In this state, the user adjusts the water level in the fry container 130 to an appropriate water level above the low water level and below the full water level, presses the start switch 155 after adding oil to the upper portion of the water, and the controller 300 performs the step 414. In step 416, the input of the start switch 155 is determined, and in step 416, the user determines the set temperature of the oil set in the temperature setting unit 340 by the temperature setting button 153, and in step 418 the temperature detecting unit After 320 determines the temperature of the current oil detected by the temperature sensor 240, and compares the set temperature and the current temperature in step 420.

When the set temperature is higher than the present temperature as a result of the comparison of the step 420, the controller 300 supplies power to the heater 220 in step 422 to heat the heat and oil, and the set temperature is lower than the present temperature. In this case, in step 424, the power of the heater 220 is cut off to maintain the temperature of the oil at the set temperature while stopping the heat generation so that the user can enjoy the fried food of the predetermined food at the set temperature.

In the next step 426, the controller 300 determines the water level detected by the water level detector 330 by the high water level sensor 211, and determines whether the water level determined by the water level sensor 211 is greater than or equal to the full water level in step 428. If the water level is not above the water level, the process returns to the step 416 to determine the set temperature and the present temperature, and to control the heating of the heater 220 according to the determined set temperature and the present temperature to maintain the temperature of the oil at the set temperature. Repeat it.

In this state, as the user performs the frying, frying flakes are generated, and the generated frying flakes accumulate in the lower water, and the water level rises. When the water level continues to rise and becomes above the full water level, the controller 300 In step 426, the water level is determined to be higher than the water level. In step 430, the heating of the heater 220 is stopped, and in step 432, the display lamp driver 370 is controlled to indicate that the current water level is higher than the water level. The alarm sound output unit 380 controls the alarm sound to output an alarm that the water level of the frying pan 130 is above the full water level, and allows the user to take a predetermined action. For example, the water stored in the frying pan 130 is slightly discharged through the water outlet valve 270 to take measures such as lowering the level of the frying pan 130 below the full water level.

In this state, when the water level of the frying pan 130 becomes a suitable water level below the full water level again, the controller 300 determines that the level of the frying pan 130 has been below the full water level in step 428, and the step 416. Returning to and determines the set temperature and the current temperature and repeats the operation of maintaining the temperature of the oil at the set temperature by controlling the heating of the heater 220 through the heater driving unit 350 according to the determined set temperature and the current temperature.

On the other hand, when the washing mode is set by the mode selection switch 290 as a result of the determination in step 408, the controller 300 detects the washing level sensor 230 by the water level detector 330 in step 434. The present water level in the fry container 130 is determined, and the display lamp 157 of the display lamp driving unit 37 is selectively lit to be displayed. In step 436, the current water level in the fry container 130 is the washing water level sensor ( It is determined whether 230) is above the installed washing level.

If the result of the determination of the step 436 is not equal to or greater than the washing water level, the process returns to step 434 to determine the current water level in the fry container 434, and selectively selects the display lamp 157 of the display lamp driving unit 37. Turn it on and let the user put water above the washing level.

In this state, when the water level of the frying pan 130 becomes more than the washing water level, the controller 300 determines whether or not the signal of the start switch 155 is input in step 438, When a signal is input in step 440 automatically set the washing temperature for washing the frying pan 130, for example, the temperature of the washing water is set to 98 ℃.

In the next step 442, the controller 300 determines the current temperature of the washing water detected by the temperature detector 320 by the temperature sensor 240, and compares the current temperature and the set temperature of the determined washing water in step 444. In comparison, when the set temperature is higher than the present temperature, the controller 300 supplies power to the heater 220 in step 446 to heat the heating and washing water, and when the set temperature is lower than the present temperature in step 448. By maintaining the temperature of the washing water at a set temperature while stopping the heat generation by cutting off the power of the heater 220 in the) it allows the user to simply wash the frying pan 130 with the washing water heated to the set temperature.

In addition, the temperature detector 320 may not accurately detect the temperature due to damage of the temperature sensor 240 in the state of operation as described above, and thus the controller 300 continuously generates the heater 220 to generate a temperature. For example, when the overheat temperature is 250 ° C. or higher, a thermostat, which is a temperature sensor installed on one side of the heater 220, detects an abnormal overheat, cuts off the power supply, and stops the operation of the table fryer 100. This prevents the occurrence of safety accidents.

As described in detail above, the present invention, in the cooking mode, it is possible to put the water within the predetermined proper level in the fry container, as well as to prevent the heater from heating when the temperature is higher or lower than the appropriate level. When the water level is high, it is possible to prevent the generation of water vapor in advance, as well as to prevent the carbonization by accumulating the generated fried debris in the water.

In addition, the present invention can be cleaned in the washing mode by heating the washing water put into the frying pan in the washing mode, the washing water level is set at a position higher than the installation position of the heater, the washing water above the set washing water level It is possible to prevent the heater from being damaged by letting the heater generate heat only when is stored.
