Description

This disclosure relates to a commercial fryer that heats cooking oil in an oil vat and cooks food by placing it in the oil vat.

The fryer heats cooking oil contained in an oil vat to a predetermined cooking temperature using heating means such as a burner or a pulse burner, thereby cooking foods such as potatoes placed in the oil vat.
As disclosed in Patent Document 1, the control means for the heating means is capable of executing a first cooking mode in which the heating means is controlled at a predetermined first heat amount when the cooking oil contained in the oil tank is a predetermined first oil amount and the food to be cooked is a predetermined first rated amount, and a second cooking mode in which the heating means is controlled at a predetermined second heat amount greater than the first heat amount when the cooking oil is a predetermined second oil amount greater than the first oil amount and the food to be cooked is a predetermined second rated amount greater than the first rated amount.

JP 2020-22576 A

Conventional fryers such as those described in Patent Document 1 have the advantage that they can be used as needed between a first cooking mode that eliminates the waste of cooking oil and suppresses deterioration of the cooking oil, and a second cooking mode that can cook a large amount of food at once. However, because the rated amount of food to be cooked differs for each cooking mode, there is a risk that a cook will mistakenly put in the wrong rated amount of food for the cooking mode selected.

The present disclosure therefore aims to provide a fryer that can prevent the rated amount of food that does not correspond to the cooking mode from being mistakenly put in.

In order to achieve the above object, a first configuration of the present disclosure includes an oil tank capable of accommodating cooking oil;
An oil storage section capable of storing a predetermined amount of cooking oil and adding it to the oil tank;
A heating means provided in the oil tank for heating cooking oil;
A control means for controlling the heating means;
A display means for displaying a control state by the control means;
an oil booster pipe connected from the oil booster reservoir to the oil tank;
An oil booster opening/closing means for manually opening and closing the oil booster pipe;
an oil increase detection means for detecting an open/close state of the oil increase opening/ closing means,
The control means controls the heating means in a predetermined first cooking mode for heating and cooking a predetermined first rated amount of food when cooking oil is not added to the oil vat from the oil addition reservoir, and controls the heating means in a predetermined second cooking mode for heating and cooking a predetermined second rated amount of food, which is greater than the first rated amount, when cooking oil is added to the oil vat from the oil addition reservoir.
The control means, when cooking oil is not added to the oil vat from the oil addition storage section, causes the display means to display the first cooking mode and the first rated amount, and when cooking oil is added to the oil vat from the oil addition storage section, causes the display means to display the second cooking mode and the second rated amount,
The control means is characterized in that when it detects via the oil increase detection means that the oil increase opening/closing means has changed from an open state to a closed state, it switches the display of the display means from a display indicating the first cooking mode and the first rated amount to a display indicating the second cooking mode and the second rated amount .
A second configuration of the present disclosure includes an oil tank capable of accommodating cooking oil;
An oil storage section capable of storing a predetermined amount of cooking oil and adding it to the oil tank;
A heating means provided in the oil tank for heating cooking oil;
A control means for controlling the heating means;
A display means for displaying a control state by the control means;
A filtering tank for filtering the cooking oil in the oil tank;
an oil supply pipe connecting the filtering tank and the oil supply reservoir;
A pump provided in the fuel supply pipe;
a fuel filler opening/closing means for manually opening and closing the fuel filler pipe;
a fuel supply detection means for detecting an open/close state of the fuel supply opening/closing means;
An overflow path that guides the cooking oil overflowing from the oil storage section to the oil tank ,
The control means controls the heating means in a predetermined first cooking mode for heating and cooking a predetermined first rated amount of food when cooking oil is not added to the oil vat from the oil addition reservoir, and controls the heating means in a predetermined second cooking mode for heating and cooking a predetermined second rated amount of food, which is greater than the first rated amount, when cooking oil is added to the oil vat from the oil addition reservoir.
The control means, when cooking oil is not added to the oil vat from the oil addition storage section, causes the display means to display the first cooking mode and the first rated amount, and when cooking oil is added to the oil vat from the oil addition storage section, causes the display means to display the second cooking mode and the second rated amount,
The control means drives the pump when the fuel supply opening/closing means is detected to be in an open state by the fuel supply detection means, and stops driving the pump when the control means detects that the fuel supply opening/closing means is in a closed state.
The control means is characterized in that when it detects that the oil supply opening/closing means has changed from an open state to a closed state while the display means is displaying the second cooking mode and the second rated amount, it switches the display of the display means to display the first cooking mode and the first rated amount .

According to the present disclosure, when cooking oil is not added to the oil vat, the control means causes the display means to display the first cooking mode and the first rated amount, and when cooking oil is added to the oil vat, causes the display means to display the second cooking mode and the second rated amount, thereby preventing the erroneous addition of a rated amount of food that does not correspond to the cooking mode.
In particular, in the first configuration , the display of the cooking mode and rated amount automatically switches even when cooking oil is added to the oil tank by manual operation, effectively preventing the erroneous addition of a rated amount of food that does not correspond to the second cooking mode.
In particular, in the second configuration , the display of the cooking mode and rated amount automatically switches even when fuel is added after manual filtering, effectively preventing the erroneous introduction of a cooked part with a rated amount that does not correspond to the first cooking mode.

Basket hangers 29, 29 for suspending and supporting the baskets 9, 9 are fixed to the protective covers 28. The outlet 19 of the overflow section 18 is provided below the basket hangers 29.

A filtering tank 30 having a filter at the bottom is provided at the bottom of the vessel body 2. An oil drain pipe 31 is connected to the bottom of the oil vat 3, and cooking oil in the oil vat 3 can be drained through the oil drain pipe 31 to the filtering tank 30. The oil drain pipe 31 is provided with an oil drain valve 32 that can be opened manually.
A filtering pump 35 is provided at the bottom of the device body 2. The suction side of the filtering pump 35 is connected to the bottom of the filtering tank 30 via a suction pipe 36. The discharge side of the filtering pump 35 branches into a first fuel supply pipe 37 and a second fuel supply pipe 38. The first fuel supply pipe 37 is connected to the fuel supply pipe 15 upstream of the fuel supply valve 16. The first fuel supply pipe 37 is provided with a first fuel supply valve 39 that is manually opened and closed. The first fuel supply valve 39 is provided with a fuel supply open/close detector (e.g., a reed switch) 56 that detects the open/close state.
The second oil supply pipe 38 is connected to the lower part of the oil tank 3. The second oil supply pipe 38 is provided with a second oil supply valve 40 that can be opened and closed manually.

An oil tank 45 using a 18L can is provided below the oil tank 3. The oil tank 45 is placed on a stand 46 provided on the vessel body 2. The stand 46 is provided with a heater 47 for heating the oil tank 45 and a tank temperature sensor 48 for detecting the temperature of the oil tank 45.
The lower end of an oil supply pipe 49 is inserted into the oil supply tank 45. The upper end of the oil supply pipe 49 is connected to the oil tank 3 above the second cooking section 8. An oil supply pump 50 and an oil supply solenoid valve 51 are provided in the oil supply pipe 49 from the upstream side.

A fry controller 60 is provided on the upper front surface of the device body 2. The fry controller 60 has an operation panel 61. As shown in Fig. 3, the operation panel 61 is provided with a power switch 62, a plurality of cooking buttons 63, 63..., and displays 64, 64 for the selected cooking mode and maintenance menu, etc., as well as a mode selection button 65 for selecting a cooking mode, and rated amount display lamps 66A, 66B for displaying the rated amount. The rated amount display lamp 66A corresponds to the first rated amount, and the rated amount display lamp 66B corresponds to the second rated amount.
A burner controller 70 is provided at the bottom of the device body 2. The burner controller 70 controls the ON/OFF of the pulse burner 4 according to the cooking mode instructed by the fry controller 60 to cook food such as potatoes. Detection signals from the first and second oil surface temperature sensors 11 and 12, the cooking temperature sensor 13, the oil refill temperature sensor 17, the tank temperature sensor 48, the oil refill opening/closing detection unit 55, the oil supply opening/closing detection unit 56, etc. are input to the burner controller 70. Based on these detection signals and instructions from the operation panel 61, the burner controller 70 controls the pulse burner 4, the gas solenoid valve 22, the fan 24, the electric heater 33, the filtering pump 35, the heat retention heater 47, the oil refill pump 50, the oil refill solenoid valve 51, etc.

In the fryer 1 configured as described above, the amount of food to be cooked at one time is set to two types, a first rated amount and a second rated amount that is larger than the first rated amount, and cooking is possible in a first cooking mode corresponding to the first rated amount and a second cooking mode corresponding to the second rated amount. The cooking oil tank 14 is filled with cooking oil (refilled oil amount).
(First cooking mode)
First, when cooking the first rated amount of food, cooking oil (first oil amount) is stored in the oil tank 3 up to the top of the first cooking section 7, as shown by the diagonal lines in Fig. 4 (A). In this state, when the cook turns on the power switch 62 of the operation panel 61, the burner controller 70, which has confirmed the cooking oil up to the top of the first cooking section 7 by the first oil surface temperature sensor 11, rotates the fan 24 for a predetermined time to supply air, and then intermittently burns the mixed gas in the combustion chamber 5 to operate the pulse burner 4 on and off. That is, the mixed gas is ignited in the combustion chamber 5 to cause it to explode and burn in the combustion chamber 5, and the combustion exhaust is forcibly discharged to the tail pipe 6 due to the pressure increase in the combustion chamber 5 caused by the combustion. Then, fuel gas and combustion air are sucked into the combustion chamber 5, which is under negative pressure due to the discharge of the combustion exhaust. By repeating this on and off operation, the cooking oil stored in the oil tank 3 is heated.
Burner controller 70 monitors the detected temperature obtained from cooking temperature sensor 13. When it is confirmed that the temperature of the cooking oil has reached a predetermined cooking temperature (e.g., 160° C.), fry controller 60 notifies the user by, for example, outputting a display indicating that cooking is OK on display unit 64 of operation panel 61.

Next, the cook selects the first cooking mode with the mode selection button 65. The fry controller 60 then causes the display unit 64 to indicate that it is in the first cooking mode, and turns on the rated amount display lamp 66A to indicate that the first rated amount is being used.
When this notification is given, the cook puts a basket containing the first rated amount of food into the oil vat 3. At this time, the first cooking mode is displayed on the display unit 64 of the operation panel 61, and the rated amount display lamp 66A is lit, so that the cook is less likely to put in the wrong amount of food.
When the cook presses the cooking start button (here, the cooking button 63 on the left side), the burner controller 70 heats and cooks the food to be cooked for a first cooking time preset in correspondence with the first rated amount and with the first heat amount of the pulse burner 4. When the first cooking time is up, the fry controller 60 sounds an alarm to notify the end of cooking. The cook then lifts the basket 9 out of the oil vat 3. If the cook wishes to continue cooking at the first rated amount, the cook can simply add the food to be cooked and press the cooking start button, and the same control process will be repeated.

(Switching from the first cooking mode to the second cooking mode)
When switching from the first cooking mode to the second cooking mode, it is necessary to increase the amount of cooking oil from the oil increase tank 14 .
Therefore, when the cook manually opens the oil refill valve 16, the cooking oil in the oil refill tank 14 is supplied to the upper end of the second cooking section 8 of the oil vat 3 through the oil refill pipe 15, as shown by the diagonal lines in Fig. 4(B), and the oil refill tank 14 becomes empty. The opening operation of the oil refill valve 16 is detected by the burner controller 70 through the oil refill opening/closing detector 55.
When the oil refill valve 16 is closed and this closing operation is detected by the burner controller 70 via the oil refill opening/closing detector 55, the fry controller 60 displays on the display 64 that the cooking mode is the second cooking mode, turns off the rated amount indicator lamp 66A, and turns on the rated amount indicator lamp 66B, thereby announcing that the cooking mode has been switched to the second rated amount. This mode switching notification may be made immediately upon detecting the opening and closing of the oil refill valve 16, or may be made after a predetermined oil refill completion time (e.g., one minute) is counted from the opening to the closing of the valve, and the valve is confirmed to be closed after the time has elapsed. An oil refill completion time may be set to be counted for a while after the valve is closed.
On the other hand, when burner controller 70 confirms via second oil surface temperature sensor 12 that the cooking oil supplied to oil tank 3 has reached the upper end (second oil amount) of second cooking section 8, it monitors the detected temperature obtained from cooking temperature sensor 13. Then, when it confirms that the temperature of the cooking oil has reached a predetermined cooking temperature, fry controller 60 notifies the user by, for example, outputting a display indicating that cooking is OK on display 64 of operation panel 61.

When this notification is given, the cook puts the basket 9 containing the second rated amount of food into the oil vat 3. At this time, the second cooking mode is displayed on the display unit 64 of the operation panel 61, and the rated amount display lamp 66B is lit, so that the cook is less likely to put in the wrong amount of food.
When the cook presses the cooking start button, the burner controller 70 heats and cooks the food for a second cooking time preset in accordance with the second rated amount and with a second amount of heat greater than the first amount of heat in the first cooking mode. This second amount of heat is obtained by operating the electric heater 33 in addition to the pulse combustor 4. However, the second amount of heat may be obtained by increasing the gas input only with the pulse combustor 4 without using the electric heater 33.
When the second cooking time is up, the fry controller 60 sounds an alarm to notify the completion of cooking. The cook then removes the basket 9 from the oil tank 3. If the cook wishes to continue cooking at the second rated amount, he or she can simply add food and press the cooking start button, and the same control process will be repeated.

(Switching from the second cooking mode to the first cooking mode)
When switching from the second cooking mode to the first cooking mode, which uses a smaller amount of oil, the cook opens the oil drain valve 32 from the second oil amount state shown in Figure 4 (B) and drains all of the cooking oil in the oil tank 3 into the filtering tank 30, as shown by the diagonal lines in Figure 5 (A).
Next, the first fuel supply valve 39 of the first fuel supply pipe 37 is opened, the second fuel supply valve 40 of the second fuel supply pipe 38 is closed, and the fuel boost valve 16 of the fuel booster pipe 15 is closed. Then, the burner controller 70 detects the opening of the first fuel supply valve 39 by the fuel supply open/close detection unit 56 and drives the filtering pump 35. Thus, the cooking oil in the filtering tank 30 is filtered and then supplied to the fuel booster tank 14 via the first fuel supply pipe 37 and the fuel booster pipe 15. When the fuel booster tank 14 becomes full, the cooking oil is supplied to the oil tank 3 via the overflow unit 18 as shown in FIG. 5B.
Then, when filtering is performed until the filtering tank 30 is empty, as shown in Fig. 4(A), the second amount of cooking oil supplied to the oil reserve tank 14 is supplied to the oil vat 3 via the overflow part 18, leaving only the amount of oil increased from the first amount of oil. That is, the first amount of cooking oil used in the first cooking mode is stored in the oil vat 3.

Then, when filtering is completed and the cook closes the first oil supply valve 39, the burner controller 70 detects this closure via the oil supply opening/closing detection unit 56, and stops driving the filtering pump 35.
Then, the fry controller 60, which has received information from the burner controller 70 that the first fuel supply valve 39 has been closed by the fuel supply open/close detector 56, displays on the display 64 that the mode is the first cooking mode, turns off the rated amount indicator lamp 66B, and turns on the rated amount indicator lamp 66A. This mode change notification may also be made immediately upon detecting the opening and closing of the first fuel supply valve 39, or may be made after a predetermined fuel supply completion time (for example, one minute) is counted from the time the valve is opened to the time it is closed, and the notification is made after it is confirmed that the valve has been closed after the time has elapsed. A fuel supply completion time that is counted for a while after the valve is closed may also be set.

On the other hand, during operation in the first and second cooking modes, the burner controller 70 monitors the detected temperature obtained from the tank temperature sensor 48 and controls the heat retention heater 47 to be turned ON/OFF so that a predetermined heat retention temperature is maintained in the top-up oil tank 45.
When the first and second oil surface temperature sensors 11, 12 detect a decrease in the amount of cooking oil required in either the first or second cooking mode, or when a predetermined number of cooking times is reached, the oil top-up pump 50 is driven to open the oil top-up solenoid valve 51. Then, the cooking oil liquefied in the oil top-up tank 45 is directly supplied to the oil vat 3 via the oil top-up pipe 49.

Thus, the fryer 1 of the above embodiment includes an oil tank 3 capable of accommodating cooking oil, an oil booster tank 14 (oil booster storage section) capable of storing a predetermined amount of cooking oil and boosting it to the oil tank 3, a pulse burner 4 (heating means) provided in the oil tank 3 for heating the cooking oil, a burner controller 70 (control means) for controlling the pulse burner 4, and an operation panel 61 (display means) for displaying a control state by the burner controller 70. When no cooking oil is boosted from the oil booster tank 14 to the oil tank 3, the burner controller 70 controls the pulse burner 4 in a predetermined first cooking mode for heating and cooking a predetermined first rated amount of food to be cooked, and when cooking oil is boosted from the oil booster tank 14 to the oil tank 3, the burner controller 70 controls the pulse burner 4 in a predetermined second cooking mode for heating and cooking a predetermined second rated amount of food to be cooked that is greater than the first rated amount. When cooking oil is not added to the oil vat 3 from the oil booster tank 14, the burner controller 70 causes the operation panel 61 to display the first cooking mode and the first rated amount, whereas when cooking oil is added to the oil vat 3 from the oil booster tank 14, the burner controller 70 causes the operation panel 61 to display the second cooking mode and the second rated amount.
This configuration makes it possible to prevent the rated amount of food that does not correspond to the cooking mode from being mistakenly put in.

In particular, the fryer 1 further includes an oil booster pipe 15 connected from the oil booster tank 14 to the oil tank 3, an oil booster valve 16 (oil booster opening/closing means) that can manually open and close the oil booster pipe 15, and an oil booster opening/closing detection unit 55 (oil booster detection means) that detects the open/closed state of the oil booster valve 16, and when the burner controller 70 detects via the oil booster opening/closing detection unit 55 that the oil booster valve 16 has changed from an open state to a closed state, it switches the display on the operation panel 61 from a display indicating the first cooking mode and the first rated amount to a display indicating the second cooking mode and the second rated amount.
Therefore, even when the cooking oil is increased by manual operation, the display of the cooking mode and rated amount is automatically switched, which effectively prevents the erroneous addition of a rated amount of food that does not correspond to the second cooking mode.

The fryer 1 also includes a filtering tank 30 that filters the cooking oil in the oil tank 3, a first fuel supply pipe 37 (fuel supply pipe) that connects the filtering tank 30 and the fuel tank 14, a filtering pump 35 (pump) provided on the first fuel supply pipe 37, a first fuel supply valve 39 (fuel supply opening/closing means) that can be manually opened and closed by the first fuel supply pipe 37, a fuel supply opening/closing detection unit 56 (fuel supply detection means) that detects the open/closed state of the first fuel supply valve 39, and an overflow unit 18 (overflow path) that guides cooking oil that has overflowed from the fuel tank 14 to the oil tank 3. When the burner controller 70 detects via the fuel supply opening/closing detection unit 56 that the first fuel supply valve 39 has been opened, it drives the filtering pump 35, and when it detects that the first fuel supply valve 39 has been closed, it stops driving the filtering pump 35. On the other hand, when the burner controller 70 detects that the first fuel supply valve 39 has changed from an open state to a closed state while the operation panel 61 is displaying the second cooking mode and the second rated amount, it switches the display on the operation panel 61 to a display indicating the first cooking mode and the first rated amount.
Therefore, even when fuel is added after manual filtering, the display of the cooking mode and rated amount is automatically switched, effectively preventing the erroneous introduction of a cooked portion with a rated amount that does not correspond to the first cooking mode.

The following describes a modified example.
The display of the first and second cooking modes and the first and second rated amounts on the operation panel is not limited to the above-mentioned form. For example, the first and second cooking modes may also be displayed by lamps, or the first and second rated amounts may also be displayed on the display unit. An audio notification may also be used.
In the above embodiment, the display of the cooking mode and the rated amount are switched when the transition to the first cooking mode and the second cooking mode is completed, but in addition to this, the cooking mode and the rated amount after the switch may be displayed in a flashing manner during the transition of the cooking mode after the start of oil addition or the start of oil supply after filtering, and the flashing may stop when the transition of the cooking mode is completed to display the cooking mode and the rated amount. By displaying in a flashing manner in this manner, the cook can easily know that the transition of the cooking mode is in progress and cooking is not possible.
The display means for the cooking mode and the rated amount may be provided separately from the operation panel. For example, a display unit may be provided on the protective cover or exhaust pipe cover behind the oil vat.
In the above embodiment, when the oil refilling and the oil refilling after filtering are performed manually, this is detected and the display of each cooking mode and rated amount is switched, but the display of each cooking mode and rated amount may also be switched when the oil refilling and the oil refilling after filtering are performed automatically by operating the operation panel.

The fryer is not limited to one having a fry controller and a burner controller separately provided, but may be one having a single controller having both the functions of a fry controller and a burner controller.
The heating means may be formed only of a pulse combustor or only of an electric heater. The heating means may be formed only of a gas burner provided outside the oil vat. Furthermore, the heating means may be formed of a combination other than the combination of a pulse combustor and an electric heater.
In the above embodiment, a pair of oil tanks are provided on the left and right sides, but the number of oil tanks may be one, or conversely, three or more oil tanks may be provided.
The present disclosure is also applicable to a pressure fryer in which the opening of the oil tank is closed with a lid.
