Description

[Detailed description of the invention] The present invention relates to a fryer for frying foods.

Generally, the oil temperature for frying is limited to the order of 10,000°C, and frying will rarely be carried out under oil salts of less than 10,000°C or more than 200°C as the temperature is too low or too high.

In this case, in the flier where the oil temperature is set for each digit, the digit of 100o0 of the set oil temperature is only 1.

The present invention has been made based on this viewpoint, and its feature is that the oil temperature can be set in order to improve operability by eliminating the need to set the 100°C digit when setting the oil temperature. The setting means consists of two setting sections for arbitrarily setting the digits of 10°C and 1°C.The digit of 10,000 is fixed to 1.

A flyer according to an embodiment of the present invention will be described below.

Incidentally, microwave heating is also used in this fryer in order to shorten the frying time. In other words, in general, the dielectric loss of food is sufficiently large compared to the dielectric loss of oil, so when microwaves are applied to a place where food and oil exist, most of the microwaves are absorbed by the food, and therefore microwave heating is difficult. In the combined fryer, the food is heated with oil from the outside and heated with microwaves from the inside, so the frying time of the food is considerably shortened.

In FIGS. 1 and 2, 1 is an oil tank, 2 is a door, 3 is a heater installed at the bottom of the oil tank 1 to heat the oil 4 put in the oil tank 1, and 5 is a built-in thermistor to keep the oil temperature. 6 is a magnetron that oscillates microwaves, 7, 7 is food, 8 is a basket in which the food is placed, 9

Reference numerals 14b denote first and second regulating portions that respectively regulate the rotation of the drive rod.

When the motor 12 is energized, the rotational force of the motor 12 causes the drive rod 13 to rotate counterclockwise until it hits the second regulating portion 14M, and the rotation rods 9a and 9b turn clockwise. ``Therefore, the above-mentioned car 8 rises.Meanwhile,
When the motor 12 is de-energized, the rotational force of the motor 2 is lost, and the car 8 is thereby lowered by its own weight.This lowering is caused by the rotation of the drive rod 13 clockwise and the first regulation. The tortoise 56 is a car switch that is turned on at the end of the rotary rod 9b when the car 8 is lowered.

Part 32 is 1℃ for arbitrarily setting the 1℃ digit of oil temperature.
This is the digit setting section.

Each of the digit setting sections 31G and 32 has four switches 3.
3, 33, . . . and outputs a 4-bit binary code by turning the switch on or off. Therefore, for example, oil spill
To set it to 300, press 4 in 1000 digit setting section 3 1.
Switch the four switches 33, 33, ... from the left to "off, off, on, off," and use the 1°C digit setting section 32 to switch the four switches 33, 33, ... from the left to "off, off, on, off."
"On". Then, the 10°C digit setting sections 31 and 1
The °C digit setting unit 32 outputs 4-bit binary codes "0010" and "0011" representing 2 and 3, respectively. 3M frying time Key group for setting microwave time 35 is a start key, 36 is a cutting knob that can be cut in two positions, ``1 cut'' and ``frying''.

Next, the operation of the flyer described above is explained using the COM shown in FIG.
The explanation will be based on a 2G program flowchart.

Normally, the knob 36 of the operating section 29 is in the "off" position.
In this case, the program cycles through steps S1, S2, and S3. In the SI step, a signal corresponding to the switching position of the knob 36 is written in the position register PST of the rCOM 20, and in the S2 step, it is determined whether the knob 36 is in the "off" position or not based on the contents of the position register PST. S
In step 3, all registers and flags in the French COM20 are cleared, and the first to third switch signals R
The output of I to R3 is completely stopped. Therefore, when performing a frying operation, the knob 36 is first switched to the "fly" position.

Then, the program exits the cycle of steps S1, S2, and S3 and proceeds to steps S4 to S7. In step S4, the current key operation on the key group 34 of the operation unit 29 is detected, and if the frying time and microwave time are set, these are set in the frying register F of the ACOM 20.
RY and microwave register MCR. Usually, the frying time is set longer than the microwave time. In step S5, the set oil temperature is written to the oil overflow register BS of the mountain COM20.

In this case, if the set oil temperature is 123℃, the IOC
1000 digit setting part 3 1 to 4 as 0 digit "2"
The bit binary signal “0010” is written, and the 1°C digit “3” is written.
" is a 4-bit binary signal from the 1°C digit setting section 32 "
0011" is written. Furthermore, loo. C digit “1”
The fixed 4-bit binary signal "000" written in the ROM (read-only memory) of COM20.
1'' is transferred and written to the oil overflow register BS.

Thus, the set oil temperature 12300 is written in the oil overflow register BS. In step S6, the third switch signal R3 is output, and the motor 12 is driven, so that the car 8 rises to come out of the oil.

At this time, the car switch 15 is turned off. In step S7, the oil overflow detected by the oil overflow detector 5 is detected by the detection register D.
It is written in the ET and displayed on the display 27. S8
In the step, the detected oil temperature in the detection register DET is "set oil temperature in the oil overflow register BS 12yo - predetermined temperature 7℃"
It is determined whether the temperature is within the desired temperature range from "set oil temperature in oil overflow register BS to 123 degrees centigrade to predetermined temperature of 7 degrees Celsius".

In this case, if the detected temperature is sufficiently low, the program reaches step S9 and the appropriate temperature flag GD is cleared.
In the following SIO step, the detected temperature is the set oil temperature 123.
It is determined whether or not the oil temperature is above .degree. C. In this case, of course, it is lower than the set oil temperature, so the program reaches the SII step. In this step, the second switch signal R2 is output and the heater 3 starts heating the oil.In the next step S2, it is determined whether the appropriate temperature flag GD is 1 or not. Since it is 0, ~ the program is SI
Returning to step SI, S2, S4 to S12 steps are cycled (hereinafter such cycle will be referred to as the first loop).

As a result, the heating of the oil progresses, and the detected oil temperature reaches ``12300 Mt.7''.
When the temperature falls within the range of 123°C to 17°C, the program exits the first loop at step S8 and returns to Si3.
Proceed to step. In this step, the appropriate temperature flag GD is set to 1. However, if the detected oil temperature is still lower than the set oil temperature, the program continues with SI0, SII.
After the steps, the process reaches step S12. Here, since the appropriate temperature flag GD is set to 1, the program then moves to S.
Proceed to step 14. In this step, it is determined whether or not the start key 35 is currently being operated, but since it is not being operated at the moment, the program then returns to the SI step and SI, S2, S4-S8, SI3, SIP-S
12, S14 steps are cycled (hereinafter, such a cycle will be repeated in the second step).
(referred to as a loop). Then, when the detected oil temperature becomes equal to or higher than the set oil temperature, the program exits the second loop at the SIO step and reaches step S15.

In this step, the output of the second switch signal R2 is stopped, and therefore heating of the oil by the heater 3 is stopped.
Next, the program goes through steps S12 and S14 and the SI
Return to step S1, S2, S4-S8, S139SI
Steps D, SI5, SI2, and SI4 are cycled (hereinafter, such a cycle will be referred to as the third loop). Then, set the oil temperature to 123
In order to maintain the temperature at q0, the program enters the third loop or the second loop depending on whether the detected oil temperature is equal to or higher than the set oil stripe of 123°C.

During this period, the detected oil temperature changed from "123℃-7℃" to "123℃".
The temperature is within the desired temperature range. Then, use the key group 34 to set the desired frying time of 4 minutes and microwave time of 2 minutes. Five transfer registers MCR are written.
Next, when the start key 31 is operated, the program exits the second loop at step S14 and reaches step S16. In this step, the output of the third switch signal R3 is stopped and the car 8 begins to descend under its own weight. ``The program remains at step SI7 until the car 8 is lowered and the car switch 15 is turned on, that is, until the foods 7, 7... are in the oil to be fried (oil heated), and the car switch 15 is turned on. Then, the process goes to steps SI8 and SI9.In step S18, weaving for every 4 minutes for the fly time and every 1/2 second for the microwave time is started in the fly register FRY and the microwave register MCR. , is output and microwave heating starts.In step SI9, "Detected oil overflow is detected at the detection register DET".
and the remaining frying time is displayed on the display 27. The path from the next S20 step to the S21 step or from the S20 step to the S22 step is the same as the path from the SIO step to the SII step or from the SIO step to the SI5 step. Subsequently, in step S23, it is determined whether the remaining fly time is 0 in the fly register FRY, but since it is not 0 now, the program proceeds to step S24.

In this step, it is determined whether the remaining microwave time is 0 in the microwave register MCR, but since this time is not 0 at the moment, the program returns to step SI9 and executes SI9, S20, S21 (or S22). ), S23, S
Cycle through 24 steps. Then, when the remaining microwave time becomes 0, the program exits this circulation state in step S24 and proceeds to step S25.

In this step, the time reduction in the microwave resistor MCR is stopped, the output of the first switch signal RI is stopped, and the microphone-q wave heating is stopped. After that, the program returns to step SI9, SI9, S20, S21, (
or S22), the steps S23 to S25 are cycled,
Next, when the remaining fly time becomes 0, such a circular state is returned to S23.
The process exits in step S26. In this step, the frying register FRY is stopped, the third switch signal R3 is output, the basket 8 is raised, and the foods 7, 7, etc. are drawn out of the oil, and the frying operation is stopped. finish.

Further, in step S26, if the first switch signal R is being output, the output of this signal is stopped, and a buzzer (not shown) is sounded to notify the end of the process. In response to this notification, the cook opens the door 2 and removes the food 7, 7.
...Take it out. Thereafter, the program L returns to the SI step and enters the second or third loop.

Then, when the knob 36 is returned to the "off" position, SI, S2,
Cycle through S3 steps. As is clear from the above description, according to the present invention, there is provided an oil tank containing oil, a heater for heating the oil, a setting means for setting the oil temperature, and a setting means for controlling the heater based on the oil overflow set by the setting means. The setting means consists of two setting sections for arbitrarily setting the digits of 100○ and 1℃, and the digit of 100:00 is fixed to 1, so the oil temperature is There is no need to set the 10th and 0th digits when making settings, and therefore a flyer with extremely excellent operability can be provided.
