Description

  The present invention relates to a fryer for frying food with cooking oil. More specifically, a mode for washing the fryer oil tank can be selected without error, and the risk of emptying the oil tank can be surely prevented. It relates to the proposal.

In kitchens in the restaurant industry such as hamburger shops and restaurants, fryer is widely used to fry a large amount of various foods such as potatoes and chicken with cooking oil. In this fryer, cooking oil stored in an oil tank built in a main body is heated by an electric heater, a gas heater, or the like, and a basket containing food such as potatoes is submerged in cooking oil in the oil tank to frying the food.
There are two types of baskets in which the food is stored: a type in which a user manually immerses the cooking oil in cooking oil in an oil tank; and a type in which the basket is automatically taken in and out of cooking oil. Furthermore, in some cases, the endless conveyor of the metal mesh on which the food is placed is immersed in the cooking oil stored in the long oil tank and moved to produce a large amount of fried food.

  Since the present invention relates to the prevention of airing at the time of washing an oil tank in a fryer, a fryer generally used in a restaurant will be described with reference to FIG. That is, the fryer 1 according to the embodiment shown in FIG. 5 includes a box-shaped cabinet 10 having an operation panel 14 on the front surface, an oil tank 12 accommodated in the cabinet 10, and an edible cooking oil stored in the oil tank 12. Is provided with a heater unit 20 for heating the container 50 to a temperature of about 150 to 180 ° C., and a lifter 30 for taking in and out the basket 50 containing the ingredients into and out of the oil tank 12. The operation panel 14 of the cabinet 10 is provided with a display 16 for displaying cooking oil temperature and error messages. The operation panel 14 is also provided with a temperature raising button SW1, a temperature lowering button SW2, and a setting button SW3 for arbitrarily setting the temperature of the cooking oil. The operation panel 14 is provided with a cooking start button SW4 and a cooking end button SW5 for taking the basket 50 into and out of the oil tank 12.

  The heater unit 20 includes an electrical box 22 whose both ends are rotatably supported at the rear of the oil tank 12, and extends from the electrical box 22 to the vicinity of the bottom of the oil tank 12 so that cooking oil in the oil tank 12 is supplied. An electric heater 24 for heating and a swing handle 26 extending substantially horizontally from one end of the electrical box 22 to the operation panel 14 side are provided. When cleaning the oil tank 12, the user grips the swing handle 26 and rotates it clockwise, whereby the electrical box 22 rotates together with the electric heater 24, and the electric heater 24 is moved above the oil tank 12. Can swing up. An oil temperature sensor 28 made up of a thermistor for detecting the temperature of cooking oil is disposed near the base end of the electric heater 24.

  The lifter 30 automatically carries the basket 50 into the oil tank 12 at the start of cooking of the food and automatically carries out the basket 50 from the oil tank 12 at the end of cooking of the food. The lifter 30 includes a movable member 32 disposed over the oil tank 12 from the back side of the electrical box 22 and a motor (not shown) disposed inside the cabinet 10. The movable member 32 includes two support columns 32a erected from the inside of the cabinet 10 on the back side of the electrical box 22, and a frame member 32c is provided forward from a plate member 32b fixed to the upper ends of the two support columns 32a. It is drooping. And the nail | claw part 52 provided in the front-end | tip of the said basket 50 is hooked by the said frame member 32c, The said basket 50 is hooked by the frame member 32c. The movable member 32 can move up and down freely, and its vertical position is adjusted by the motor inside the cabinet 10. A controller for controlling the operation of the flyer 1 is provided inside the cabinet 10.

  The above-mentioned fryer fries various ingredients with hot cooking oil, and is used every day for business such as restaurants, so the inner surface of the oil tank storing the cooking oil and the periphery of the opening are time-lapsed. Large amount of oil stains. For this reason, it is necessary to clean the fryer oil tank regularly or irregularly from the viewpoint of food hygiene. The oil tank is washed after all cooking oil stored in the oil tank is drained (for this reason, a drain cock for oil discharge is provided at the bottom of the oil tank), and water is stored inside and a designated detergent is used. A method is employed in which the washing water is boiled with a heater and boiled for a certain period of time.

When performing boiling cleaning of the oil tank in the above-described fryer, conventionally, various settings for boiling cleaning of the oil tank (heater temperature setting, heating time, etc.) are stored in the microcomputer of the controller built in the fryer. Then, after the detergent was put into the oil tank, the above settings were called from the microcomputer to perform boiling. However, in this case, the following drawbacks are pointed out.
(1) The memory for cooking stored in the microcomputer of the controller occupies one storage capacity only by setting to store the mode of boiling cleaning of the oil tank.
(2) Since the setting for boiling cleaning of the oil tank exists in the cooking memory of the controller, the user may accidentally select the setting for boiling the oil tank regardless of the situation in which the user should cook fried food. is there. At this time, since cooking oil is present in the oil tank, not cleaning water, the temperature of the cooking oil is lowered. This is because the boiling temperature setting of the wash water is considerably lower than the cooking temperature setting with cooking oil.
(3) Contrary to the case of (2) above, although the cooking oil is replaced with washing water to wash the oil tank, for example, the cooking oil temperature setting of 180 ° C. is erroneously called up in the cooking mode. Then, there is a danger that the washing water in the oil tank will boil and the water will completely evaporate and empty the oil tank.

  The invention of Japanese Patent No. 4474573 has been proposed as means for preventing the above-described state. In this invention, in addition to the cooking time (cooking time) adjustment mode in the controller built in the fryer, the boilout (oil bath boiling washing) mode is stored as a special mode, and the temperature of the oil bath is controlled. The cooking time adjustment mode can be selected. And in the normal mode, when the operation switch is turned on, the temperature control of the cooking oil in the oil tank is started, the menu in which the cooking time is set is called, the cooking time is started, and the predetermined cooking time is counted up. Sound an alarm and exit cooking mode. If the temperature is not controlled, the boil-out mode can be selected on the condition that the boiling cleaning of the oil tank is started.

Japanese Patent No. 4474573

  Although the invention of the above-mentioned Japanese Patent No. 4474573 overcomes the above-mentioned drawbacks of the fryer, this invention still has a risk of performing an artificial mistake in boiling for oil tank cleaning. That is, the patent is only that the condition for shifting to the boilout (oil bath boiling) mode is “temperature control is not performed”. For this reason, for example, even when cooking for frying food is finished and the heater is de-energized, and the temperature control is cut off, high temperature cooking oil still exists in the oil tank. In this situation, if the user selects the boilout mode by mistake, the temperature control is not performed, so the condition is cleared and the boilout mode is started. Of course, the set temperature of the heater in the boil-out mode is lower than the set temperature of the heater in the cooking time mode, so even if there is no actual harm that the cooking oil boils, the meaning that the boil-out mode can be selected is lost. End up. Moreover, there is a possibility that the user misunderstands that cleaning water is contained in the oil tank and the oil tank cleaning is started, which is not preferable.

  Further, the special mode of the Japanese Patent No. 4474573 includes modes for setting various programs, and the boilout mode is set along with these modes. For this reason, in the normal mode of the operation panel, the heater generates heat when the operation switch is turned on and the temperature control is executed. In the boilout mode, the heater generates heat and the temperature is selected by selecting the special mode. This causes inconsistency that control is executed. In particular, in this patent, the heating of the flyer heater is performed by gas combustion, so this mismatch can lead to a serious accident. For example, if the special mode is selected in an empty state where cooking oil and cleaning water are not contained in the oil tank, and the user mistakenly selects the boilout mode when changing various settings, the oil tank is There is a possibility of flying, which is extremely dangerous.

In order to solve the above-mentioned problems and achieve the intended purpose, the invention according to claim 1 is an oil tank for storing cooking oil for frying food and an oil tank attached to the oil tank to bring the cooking oil to a desired temperature. A heater unit for heating, a food moving means for detaching the food from the cooking oil after being immersed in the cooking oil, a controller having a program for controlling the heater unit and the food moving means, and starting the program of the controller In a fryer equipped with a switch to be operated and an operation panel having a light emitting element for displaying the current state of various controlled objects,
The operation panel includes a switch for instructing the start of cleaning of the oil tank, and a light emitting element that is lit only when the operation of the oil tank cleaning switch is valid,
The controller stores a cooking program for performing normal fried cooking and an oil tank cleaning program for cleaning the oil tank,
When the cooking program on the operation panel is operated to start the cooking program, temperature control of the cooking oil according to the content of the cooking program is started.
The oil tank cleaning program is started by operating the oil tank cleaning switch on the operation panel on the condition that the temperature of the cooking oil is equal to or lower than a predetermined safe temperature, and is added to the oil tank instead of the cooking oil. The main point is to start the temperature control of the washed water.
According to the first aspect of the invention, when program controlling a lifter on which food is placed or an endless conveyor, the program is executed only when the user consciously selects the oil tank cleaning program. Since it can be executed, the risk of emptying the oil tank is prevented.

In order to solve the same problems as described above and achieve the intended purpose, the invention according to claim 4 is an oil tank for storing cooking oil for frying food, and a desired cooking oil attached to the oil tank. A heater unit for heating to a temperature, a controller incorporating a timer for operating the heater unit for a selected time, a timer switch for selectively instructing the timer to a time, and a light emitting element for displaying the current status of various control targets In a fryer equipped with an operation panel having
The operation panel includes a switch for instructing the start of cleaning of the oil tank, and a light emitting element that is lit only when the operation of the oil tank cleaning switch is valid,
The controller stores a cooking program for performing normal fried cooking and an oil tank cleaning program for cleaning the oil tank,
When the power of the fryer is turned on, the cooking program in the controller is started, and then when the operation switch of the operation panel is turned on, temperature control of the cooking oil is started only for a time set in the timer,
When the operation switch is not turned on, the oil tank cleaning program is started by operating the oil tank cleaning switch of the operation panel on the condition that the temperature of the cooking oil is equal to or lower than a predetermined safe temperature. And
Then, the gist of starting the temperature control of the washing water added to the oil tank instead of the cooking oil by turning on the operation switch.
According to the invention of claim 4, when the flyer that does not have the lifter or the endless conveyor is controlled by the timer, the program can be executed only when the user consciously selects the oil tank cleaning program. The danger of emptying the oil tank is prevented.

  The present invention has been proposed in view of the above-mentioned drawbacks inherent in the prior art patents, and has been proposed to overcome this drawback, with a light emitting element (LED) that independently selects an oil bath cleaning mode. By providing a switch on the operation panel, it is easy for the user to visually understand, and only when the temperature of the oil tank is below a predetermined safe temperature, the oil tank cleaning program can be selected and executed. Therefore, an effective effect of reducing the risk of emptying the oil tank is obtained.

It is the schematic which shows the control circuit of the fryer with a lifter concerning Example 1 of this invention with the operation panel incidental to this. It is a flowchart figure which shows the operation state at the time of carrying out program control of the fryer with a lifter shown in FIG. It is the schematic which shows the control circuit of the flyer which concerns on Example 2 of this invention with the operation panel incidental to this. It is a flowchart figure which shows the operation state at the time of carrying out timer control of the flyer shown in FIG. It is a partially transparent perspective view which shows the whole structure of the common flyer provided with the lifter.

  Next, with regard to a fryer according to a preferred embodiment of the present invention, control contents that can effectively prevent oil tanks from being blown will be described with reference to the accompanying drawings. Since the flyer in which the present invention is implemented is basically the flyer having the structure described in FIG. 5, the description of the above-described configuration is omitted. In the first embodiment of the present invention, the flyer with a lifter shown in FIG. 5 is controlled by a program, and in the second embodiment, a flyer without the lifter shown in FIG. 5 is controlled by a timer. Moreover, regarding the fryer of Example 1, it may replace with the lifter of a basket and may make it drive | work in an oil tank on various endless metal-mesh conveyors.

[Example 1]
FIG. 1 shows an example of a flyer-equipped controller according to the first embodiment and an operation panel attached to the flyer. FIG. 2 is a flowchart when the controller shown in FIG. 1 is program-controlled. The heater unit 20 in the flyer uses an electric heater 24 shown in FIG. 5 as a heating source. However, a gas burner or an oil burner may be used as a heating source, and the bottom of the oil tank 12 may be heated by the flame of the gas burner. The supply of gas or the like to the gas burner or oil burner is controlled by opening / closing an electromagnetic valve, and the ignition of the burner is also performed by electric means. As shown in FIG. 1, the memory in the controller 40 of the lifter with lifter according to the first embodiment is equipped with a control program 42 for electrically controlling the heater unit 20 and the lifter 30, and various types of cooking are performed. A cooking program 44 for issuing a control command corresponding to the food and an oil tank cleaning program 46 for issuing a control command for boiling cleaning of the oil tank 12 are stored.

  The controller 40 is electrically connected to various switches and displays of the operation panel 14 provided in the cabinet 10 of the flyer 1. On the left side of the operation panel 14 shown in FIG. 1, there are provided an operation switch 48 with a light emitting source using LEDs and a display 54 for displaying the temperature of cooking oil stored in the oil tank 12. A cooking program selection switch 56 is provided at the right center of the operation panel 14 to select a different cooking program according to various ingredients. In the illustrated example, the cooking program selection switches 56 are grouped into six panels, and each of the selection switches 56 has an LED light source. Below the cooking program selection switch 56, an oil tank cleaning switch 58 for giving an instruction to the oil tank cleaning program 46 is provided. The oil tank cleaning switch 58 also has a built-in LED light source, and emits light to illuminate the switch 58 when the operation is effective. A display 60 for displaying the remaining cooking time according to the selected cooking program is provided above the cooking program selection switch 56.

  In the first embodiment, the lifter with lifter shown in FIG. 5 is programmed to operate, and the operation over time by this program control will be described with reference to the flowchart of FIG. In step 10, the power switch for turning on / off the energization of the entire electric system of the flyer 1 is turned on. In this case, the operation switch 48 of the operation panel 14 may be turned on to the ON side. If this is left unattended, there is a disadvantage that the temperature control of the oil tank 12 starts suddenly when the operation switch 48 is turned on. Therefore, even if the operation switch 48 is ON, if the power switch is turned ON in Step 10, the ON operation of the operation switch 48 is invalidated and it is assumed that the operation switch 48 is in the OFF state. . Next, in step 12, it is confirmed whether or not the operation switch 48 is turned on. If the result is affirmative (YES), the LED of the operation switch 48 is turned on in step 14 and the operation panel 14 in step 16 is turned on. The LEDs of all cooking program selection switches 56 flash to prompt the user to select a cooking program to be activated. At this time, the heater unit 20 is not energized, and therefore the temperature control of the cooking oil in the oil tank 12 is not performed. Further, even when the oil tank cleaning program 46 is selected as will be described later, it is not executed unless the temperature of the oil tank 12 itself is equal to or lower than a predetermined safe temperature (for example, 100 ° C. or lower).

  Next, in step 18, it is confirmed whether or not the cooking program selection switch 56 is turned on. If this is affirmed (YES), the cooking program 44 by the selected cooking menu is started by going directly to step 20, and step At 22, temperature control of cooking oil in the oil tank 12 is started by energizing the heater unit 20. When the ON operation of the cooking program selection switch 56 is denied (NO) in step 18, the process proceeds to step 24, and the temperature of the oil tank 12 becomes equal to or lower than a predetermined safe temperature (here, 100 ° C.). Make sure that If the confirmation result is affirmative (YES), the process proceeds to step 25, and the LED of the oil tank cleaning switch 58 on the operation panel 14 is blinked to let the user know that the oil tank 12 can be cleaned. When the user visually recognizes that the LED of the oil tank cleaning switch 58 is blinking in step 25, the cooking oil in the oil tank 12 is replaced with water, and a necessary detergent is added to prepare the oil tank 12 for cleaning.

  If the confirmation result in step 24 is negative (NO), in step 26, the LED of the oil tank cleaning switch 58 is turned off. Accordingly, the user needs to replace the cooking oil in the oil tank 12 with water when the oil tank 12 contains hot cooking oil and cannot be washed. Can visually perceive. After blinking the LED of the oil tank cleaning switch 58 in step 25, the process proceeds to step 27 to check whether the oil tank cleaning switch 58 is ON. If the confirmation result is affirmative (YES), the oil tank cleaning program 46 is started in step 28, and then the routine proceeds to step 22, where the heater unit 20 is energized and temperature control of the cleaning water is started.

  As described above, when the user turns on the cooking program selection switch 56 and selects the activation of the cooking program 44, the temperature control of the oil tank 12 is immediately started, and the oil tank cleaning program 46 can never be selected or activated. There is no such thing. Actually, when the user cleans the oil tank 12, the operation switch 48 of the operation panel 14 is turned off to stop the temperature control by the heater unit 20, and then the cooking oil is recovered from the oil tank 12. . Next, after a required amount of water and detergent are put into the oil tank 12, the operation switch 48 is turned on and the oil tank cleaning program 46 is selected to clean the oil tank 12. In this case, if the oil tank cleaning program 46 can be selected from the cooking program 44, the cooking oil and water are exchanged while the temperature control by the heater unit 20 is continued. End up. When the oil and water are exchanged, the oil tank 12 is emptied even for a short time. However, since the temperature control is continued, the oil tank 2 may be empty. There is sex.

  Moreover, even if the oil tank cleaning switch 58 is selected, the selection is made effective by satisfying the condition that the oil tank 12 is at a safe temperature of 100 ° C. or lower, for example. When the oil tank cleaning program 46 is selected, the other cooking programs 44 cannot be selected. This is because when the user selects the cooking program by mistake in a state where cleaning water is stored in the oil tank 12, the set temperature of the oil tank 12 is set to 180 ° C., for example. This is to prevent a dangerous situation where the washing water in the oil tank 12 boils. In the fryer with a lifter that performs the program operation as described above, since the start switch of each program discloses the temperature control and the OFF operation of the operation switch 48 stops the temperature control, the oil tank cleaning program 46 always controls the temperature. It is safe because you will select the previous one.

[Example 2]
FIG. 3 shows an example of a flyer controller according to the second embodiment and an operation panel attached to the controller. This flyer does not include the lifter 30 shown in FIG. 5 or the above-described endless conveyor of the wire mesh, and only the heater unit 20 is the object of basic electrical control. FIG. 4 is a flowchart when the controller shown in FIG. 3 is controlled by a timer. The lifter controller 40 according to the second embodiment is provided with a timer 62 that sets heating time stepwise to turn on or off the energization of the heater unit 20. The oil temperature in the oil tank 12 is monitored by the thermistor 28, and the controller 40 turns the heater unit 20 on and off to keep it at a predetermined minimum temperature. Further, the memory of the controller 40 stores an oil tank cleaning program 46 for issuing a control command for boiling cleaning of the oil tank 12. In addition, a cooking program 44 for cooking according to the ingredients is also provided.

  The controller 40 is electrically connected to various switches and displays of the operation panel 14 provided in the cabinet 10 of the flyer 1. On the left side of the operation panel 14 shown in FIG. 3, there are provided an operation switch 48 with a light emitting source using LEDs and a display 54 for displaying the temperature of cooking oil stored in the oil tank 12. In addition, a timer operation switch 64 is provided at the center on the right side of the operation panel 14 for setting the time for frying food with cooking oil in units of minutes or seconds. In the illustrated example, the timer operation switch 64 includes a setting panel and a start switch for 1 minute, 3 minutes, 1 second, and 10 seconds, and each timer operation switch 64 has a light-emitting source using LEDs. Below the timer operation switch 64, an oil tank cleaning switch 58 for giving an instruction to the oil tank cleaning program 46 is provided. The oil tank cleaning switch 58 also has a built-in LED light source, and emits light to illuminate the switch 58 when the operation is effective. Above the timer operation switch 64, a display 60 is provided for displaying the remaining cooking time by the selected timer.

  In the second embodiment, a flyer not having a lifter is operated by a timer, and the operation over time by this timer control will be described with reference to the flowchart of FIG. In step 10, the power switch for turning on / off the energization of the entire electric system of the flyer 1 is turned on. In this case, the operation switch 48 of the operation panel 14 may be turned on to the ON side. If this is left unattended, there is a disadvantage that the temperature control of the oil tank 12 starts suddenly when the operation switch 48 is turned on. Therefore, even if the operation switch 48 is ON, if the power switch is turned ON in Step 10, the ON operation of the operation switch 48 is invalidated and it is assumed that the operation switch 48 is in the OFF state. . Next, in step 12, the cooking program 44 is activated. At this time, the LED illumination of the oil tank cleaning switch 58 is turned off.

  Next, the routine proceeds to step 14, where it is confirmed whether or not the operation switch 48 is ON. If the confirmation result is YES (affirmative), the process jumps to step 16 to start cooking oil temperature control in the oil tank 12. If the confirmation result in step 14 is negative (NO), it is confirmed in step 18 whether the oil temperature in the oil tank 12 is equal to or lower than a predetermined safe temperature (for example, 100 ° C.). If the temperature is equal to or lower than the safe temperature, the process proceeds to step 20, and it is confirmed whether the oil tank cleaning switch 58 is ON. If the ON of the oil tank cleaning switch 58 is affirmed (YES), it is confirmed in step 22 whether the cooking program 44 is activated, and if it is affirmed (YES), the oil tank cleaning program 46 is executed in step 24. At the same time, the LED of the oil tank cleaning switch 58 is turned on.

  If it is negative (NO) in step 18 that the oil temperature in the oil tank 12 is not lower than a predetermined safe temperature (for example, 100 ° C.), the process proceeds to step 26 and the oil tank cleaning switch 58 is turned on. Check if it was done. If the ON operation is affirmed (YES), the buzzer 66 provided on the operation panel 14 is sounded in step 28 to make the user audibly notice that the oil tank cleaning operation is invalid, and then go to step 12 above. Iterate over the returning loop. If the activation of the cooking program 44 is denied (NO) in step 22, the process proceeds to step 30, and the oil tank cleaning switch 58 is continuously turned off, assuming that the program to be activated is the cooking program 44.

  As described above, in the fryer that performs the timer operation, when the operation switch 48 of the operation panel 14 is turned on, the temperature control of the cooking oil in the oil tank 12 is started immediately. When the operation switch 48 is turned OFF, the cooking oil temperature control is stopped, and the oil tank cleaning program 46 selects a state before the temperature control is performed. In the specific oil tank cleaning operation, the water temperature is first raised to the set temperature of the oil tank cleaning, and when it reaches the set temperature, the preset cleaning time is counted, and after completion of the counting, the buzzer is sounded and the display blinks End. Let Since the cleaning is completed at this time, the temperature control is stopped. By doing so, it is possible to eliminate unnecessary temperature adjustment when the user is performing other work and is not aware of the completion of cleaning. In addition, when the cleaning is completed and it is desired to continue the cleaning, the same cleaning as before can be performed by pressing the oil tank cleaning switch again.

  Incidentally, when the flyer with a lifter shown in FIG. 5 is subjected to the program operation described with reference to the flowchart shown in FIG. 2, there are some suggestions for improving some of the disadvantages associated therewith. The fryer provided with the lifter 30 sets cooking oil temperature and frying time as a program, and controls the lifting and lowering operation of the lifter 30 according to the program. As a result, the user can perform other operations while the food is being fried, and has the advantage that the food can be fried as much as possible evenly. However, in the latter case, the temperature of the cooking oil in the oil tank 12 when starting the program for lowering the lifter 30 greatly affects the quality of the food. For this reason, the lifter 30 is lowered with a certain temperature range with respect to the oil temperature stored in the program. However, it is difficult to set the temperature range to what extent. In other words, if the temperature range to be set is too narrow, the instruction timing for lowering the lifter by the program will be delayed. End up.

  Even if the user selects a program for lowering the lifter 30 in the controller 40 shown in FIG. 1, the lowering of the lifter is not immediately instructed by the oil temperature set in the program, but ± 3K ( The program operation is not started unless it becomes Kelvin). This is to suppress as much as possible the difference that occurs in the frying of the food depending on the amount of the food fried with oil. For example, when the technique disclosed in Japanese Patent Application Laid-Open No. 2007-244672 is adopted for the program operation, in order to minimize the temperature drop of the cooking oil in the oil tank 12 when the lifter 30 is lowered, The program operation is started after reaching a temperature range in which the heater unit 20 can be forcibly turned on simultaneously with the descent.

  By the way, the heating source of the fryer is the electric heater 24 of the heater unit 20, a gas burner, or the like, and this heating is performed in order to minimize the drop in oil temperature when food is put into cooking oil and fried cooking is started. Generally, the ON / OFF control of the source is performed on a small basis. However, even if the heating by the heating source is switched from ON to OFF, the cooking oil in the oil tank 12 continues to rise in temperature for a while due to residual heat. At this time, when the food to be fried is not put in, the oil temperature is controlled to -2K to + 8K (Kelvin) with the measured value with respect to the set temperature of the program, and when the outside air temperature is normal temperature, the temperature control interval is 5 minutes -10 minutes. If the temperature range within which the program can be started is narrow with respect to the temperature range to be controlled, the worst case from when the program is selected to when the program is started despite the oil temperature being controlled. In some cases, it may take as long as 5 minutes. Therefore, there is a problem that the user cannot take a urgent action as it is. In other words, the temperature range in which the program can be started can be handled by setting the temperature range to be equal to or higher than the control temperature range, but the purpose of the autolift flyer for uniforming the lifting cannot be sufficiently satisfied.

  Therefore, the temperature range at which the program can be started satisfies the specifications as an autolift fryer and is left as it is. When the user wants to cook quickly, the program can be forcibly started by pressing the program switch for 1 second again after selecting the program. The intention to hold the button for 1 second is to prevent erroneous operation and to recognize that cooking has started at the user's discretion. Note that the temperature at which the program can be forcibly started may be limited. For example, when the lift is not allowed (raw) when the lift is not sufficient (raw), the above operation is enabled when the temperature is higher than the set temperature, and disabled when the temperature is lower than the set temperature. Also good. In addition, when the program is forcibly started at the set temperature + 3K or more, the control disclosed in Japanese Patent Application Laid-Open No. 2007-244672 is not entered. This is because when the temperature is high, the heater is not forcibly turned on, priority is given to the temperature drop, and the frying is brought closer to the case where cooking is performed in the program start temperature range as much as possible.
