Description

TECHNICAL FIELD The present invention relates to a fryer for commercial use in which cooking oil is heated in an oil tank, and ingredients are put into the oil tank and cooked.

The fryer heats the cooking oil contained in the oil tank to a predetermined cooking temperature by means of a heating means such as a burner or a heating element, thereby cooking the foodstuff put into the oil tank. For example, in Patent Document 1, a small amount of cooking oil of about 30 to 40 pounds is stored in an oil tank, and a basket containing a rated amount (680 g) of potatoes is put into the oil and cooked. A fryer is disclosed which is adapted to be replenished with cooking oil from time to time.

Japanese Patent No. 5340962

In such a fryer, cooking is normally performed in a first cooking mode in which a first rated amount (for example, 680 g) of food is heated with a first amount of cooking oil (for example, 35 pounds). During busy hours, a second cooking mode in which the amount of cooking oil and food is increased to heat a second rated amount (e.g., 900 g) of food with a second amount of oil (e.g., 45 pounds) of cooking oil. I need to do the cooking. Therefore, although most of the day can be covered by the first cooking mode, it is necessary to increase the size of the oil bath for the second cooking mode. As a result, the size of the entire fryer increases, leading to an increase in cost. In addition, since the oil tank becomes bulky upward, it is difficult to take in and out the food to be cooked and to clean it, which may adversely affect cooking performance and maintainability.

Therefore, the present invention can suppress an increase in cost by suppressing an increase in the size of the oil tank even if cooking in both the first cooking mode and the second cooking mode is possible, and at the same time, the ease of cooking and the ease of maintenance are not impaired. It is intended to provide a fryer that does not

The oil supply pipe 26 is provided with an oil supply valve 27 which is an electromagnetic valve.

A controller 30 as control means is provided at the front lower portion of the body. This controller 30 monitors the cooking oil temperature detected by a temperature control thermistor 31 provided in the oil tank 2 according to a menu selected by an operation panel (not shown) provided on the front of the vessel body, and controls the temperature of the pulse burner 3. ON/OFF control is performed to cook food such as potatoes. This cooking will be explained based on the flow chart of FIG.
Here, the amount of food to be cooked at one time is of two types, a first rated amount (eg 680 g) and a second rated amount (eg 900 g) which is larger than that. When cooking the food to be cooked, the oil tank 2 stores cooking oil (approximately 35 pounds) up to the upper end (L1 shown in FIG. 1) of the first cooking portion 6 . In this state, when the operation switch on the operation panel is turned on in S1, the controller 30 rotates the fan 18 for a predetermined time to supply air, and then intermittently burns the mixed gas in the combustion chamber 4 in S2 for pulse combustion. Operate the device 3. That is, a spark plug provided in the combustion chamber 4 ignites the mixed gas to cause explosive combustion in the combustion chamber 4, and the pressure rise in the combustion chamber 4 accompanying the combustion forces the combustion exhaust to the tail pipe 5. The cooking oil stored in the oil tank 2 is heated by repeating the operation (ON/OFF operation) of discharging the fuel gas and the combustion air into the combustion chamber 4, which becomes negative pressure due to the discharge of the combustion exhaust gas. .

Next, the controller 30 monitors the detected temperature obtained from the temperature control thermistor 31, and when it is confirmed in S3 that the temperature of the cooking oil has reached a predetermined cooking temperature (for example, 180 to 182° C.), the operation panel In this case, the user is notified by outputting a display indicating that cooking is OK.
When this notification is given, the cook puts the basket containing the food to be cooked into the oil tank 2.例文帳に追加At this time, since a small amount of the first rated amount of the food to be cooked is put into the first cooking portion 6, the food to be cooked is positioned below the oil surface of the first cooking portion 6 and is entirely covered with cooking oil. I will get caught.
Then, in S4, the cooking mode by operating the operation panel is discriminated. Here, when the first cooking mode is selected and the cooking start button provided on the operation panel is pressed in S5, the controller 30 controls in S6 the first cooking preset corresponding to the first rated quantity. The food is cooked with the time and the first heat quantity of the pulse burner 3 . Then, when the time is up in S7, an alarm is sounded in S8 to notify the completion of cooking. The cook lifts the basket out of the oil tank 2. In the case of continuing to cook with the first rated amount, if the food to be cooked is put in and the cooking start button is pressed, the processing from S5 onwards is repeated.

When the second rated amount of food, which is larger than the first rated amount, is put in while the first cooking mode is selected, the small amount of the first oil stored in the first cooking unit 6 reaches the level of the first oil. The food to be cooked is exposed from the Therefore, the operator can immediately grasp that the amount is incorrect and can redo the cooking.

On the other hand, when cooking the second rated amount of food, the oil tank 2 needs to store cooking oil (approximately 45 pounds) up to the upper end of the second cooking portion 7 . At this time, if the second cooking mode is selected in S4, the controller 30 opens the oil replenishment valve 10 in S9 to supply the cooking oil in the oil tank 8 to the oil tank 2 through the outlet pipe 9, Cooking oil is supplied up to the upper end (L2 shown in FIG. 1) of the second cooking portion 7 . The amount of oil reaching the second cooking section 7 can be confirmed by an oil surface thermistor 32 provided in the oil tank 2 .
Next, the controller 30 monitors the detected temperature obtained from the temperature control thermistor 31, and when the temperature of the cooking oil reaches a predetermined cooking temperature (for example, 180 to 182° C.) in S10, the operation panel indicates that cooking is OK. Notify by outputting the display of

When this notification is given, the cook puts the basket containing the food to be cooked into the oil tank 2.例文帳に追加At this time, the second rated amount of the food to be cooked is put into the second cooking portion 7, which has a large amount of oil, so that the entire food to be cooked is submerged below the oil surface of the second cooking portion 7. Become. Moreover, even if the amount of oil is large, the second cooking portion 7 is widened in a reverse tapered shape, so that the oil surface is less bulky.
Then, when the cooking start button is pressed in S11, the controller 30 controls in S12 the second cooking time preset corresponding to the second rated amount and the second heat amount of the pulse combustor 3 to be cooked. Cook things with heat. This second amount of heat is set to be larger than the first amount of heat in the first cooking mode. When the time is up in S13, an alarm is sounded in S14 to notify the completion of cooking. The cook lifts the basket out of the oil tank 2. In the case of continuing to cook with the second rated amount, if the food to be cooked is put in and the cooking start button is pressed, the processing from S11 onwards is repeated.

On the other hand, the controller 30 monitors the position of the oil level in the oil tank 8 with the oil level sensor 15 during operation, and when the oil level in the oil tank 8 falls below a predetermined position due to replenishment of cooking oil to the oil tank 2, 3, the electric heater 13 is operated to melt the solid oil in the oil container 11 and the oil supply pump 14 is operated to supply the cooking oil in the oil container 11 to the oil tank 8 . At this time, if a predetermined position detection signal is not obtained from the oil level sensor 15 even after a predetermined period of time has passed since the oil supply pump 14 was operated, the controller 30 determines that the solid oil in the oil container 11 has run out. It makes a decision, stops the oil supply pump 14, and informs that fact.

In addition, when shifting from the second cooking mode to the first cooking mode with a small amount of cooking, a pipe to a spare tank (not shown) is connected to the drain oil valve 23, and the oil drain valve 23, which is a three-way valve, is operated. , the cooking oil in the oil tank 2 may be drained to the reserve tank until the oil level drops to the upper end of the first cooking section 6 . Alternatively, the water may be discharged to the filtering tank 21 instead of the reserve tank.
Furthermore, when filtering the cooking oil in the oil tank 2 , after turning off the operation switch, the oil drain valve 23 is operated to discharge the cooking oil in the oil tank 2 to the filtering tank 21 . When the filtering switch on the operation panel is operated, the filtering pump 24 starts operating to suck the cooking oil drained into the filtering tank 21 through the suction pipe 25 and return it to the oil tank 2 through the oil supply pipe 26. - 特許庁As a result, the filter provided on the bottom surface of the filtering tank 21 can filter the cooking oil.

(Effects of invention related to two cooking modes)
Thus, according to the fryer 1 of the above embodiment, the controller 30 outputs a pulse when the amount of cooking oil contained in the oil tank 2 is the predetermined first oil amount and the amount of the food to be cooked is the predetermined first rated amount. A first cooking mode in which the combustor 3 is controlled with a predetermined first heat quantity to cook the food to be cooked; and a second cooking mode for cooking the food by controlling the pulse burner 3 with a second predetermined heat quantity larger than the first heat quantity when the second rated quantity is higher than the rated quantity. Since it is possible to cook the first rated amount of cooked part with a small amount of cooking oil, it is possible to suppress the contamination of the cooking oil and to take a long span for changing the cooking, while during the busy time zone , cooks with a large amount of cooking oil with a relatively high calorie, so that the temperature drop of the cooking oil due to cooking can be suppressed. Therefore, even if the second rated amount of food is continuously cooked, the quality of the food is not deteriorated, and the food can be smoothly provided. That is, it is possible to cook a large amount of food even during busy times such as lunchtime while maintaining the advantage of cooking with a small amount of cooking oil (cooking oil durability).

In the above embodiment, when the cook selects from the first cooking mode to the second cooking mode on the operation panel, the controller automatically replenishes the oil tank with cooking oil and cooks with the second cooking time and the second heat amount. Although it is designed to be executed, replenishment of cooking oil can also be performed manually. That is, the oil replenishing valve may be manually operated to replenish the cooking oil to the second cooking section, and then the second cooking mode may be selected to perform cooking with the set second cooking time and second heat amount. .
Conversely, the oil replenishment valve and the oil drain valve are electrically operated, and when the first cooking mode is changed to the second cooking mode, the controller automatically operates the oil replenishment valve to execute the second cooking mode. When shifting from the second cooking mode to the first cooking mode, the controller may automatically operate the oil drain valve to drain the cooking oil from the second cooking section and execute the first cooking mode in full auto mode. good.

Alternatively, the first cooking mode and the second cooking mode may be executed completely manually. That is, when cooking the first rated amount, the amount of cooking oil is set to the first amount by manually operating the oil drain valve or the like, and the pulse burner is set to the first heat amount to cook the food to be cooked. When cooking two rated amounts, the cooking oil is set to the second amount by manually operating the oil replenishment valve or the like, and the pulse burner is set to the second heat amount to cook the food.

Furthermore, in the invention relating to the two cooking modes, since the oil tank and replenishing means by the oil tank are not essential, when executing the second cooking mode by manual operation, from the external 18-liter can etc. to the second cooking section You can add cooking oil. As for the increase in the heat quantity in the second cooking mode, the heat quantity of the pulse combustor may be increased, or an auxiliary heat source such as an electric heater or burner may be used. When shifting from the second cooking mode to the first cooking mode, it is also possible to reduce the amount of heat in stages, such as reducing the amount of heat according to the temperature change of the cooking oil.
In addition to the pulse combustor, a burner or an electric heater can also be used as the heating means, and the shape of the oil tank is not limited to the reverse tapered shape of the second cooking section, and can be changed as appropriate.

(Effects of invention related to oil refilling means)
On the other hand, according to the fryer 1 of the above configuration, the oil container 11 containing the solid oil, the solid oil heating means (the electric heater 13) for heating the solid oil in the oil container 11, and the heated and liquefied oil container 11 an oil replenishing means for supplying the cooking oil inside to the oil tank 2, the oil replenishing means being an oil tank 8 installed above the oil tank 2, and an oil container 11 and the oil tank 8 being connected to supply oil. A supply path (supply pipe 12) capable of supplying the cooking oil in the oil container 11 to the oil tank 8 by the pump 14 is connected to the oil tank 8 and the oil tank 2 to supply the cooking oil in the oil tank 8 to the oil tank 2. A considerable amount of solid oil can be stored in the oil tank 8 installed above the oil tank 2 by including a lead-out path (outlet pipe 9) that can be supplied and an opening/closing means (oil replenishment valve 10) for opening and closing the lead-out path. can be stored in a liquefied state. Therefore, by replenishing the oil tank 8 from the oil container 11 at the timing when the cooking oil in the oil tank 8 has a certain margin, the volume reduction of the cooking oil in the oil tank 2 can be immediately dealt with. You can cook without Therefore, it is not necessary to operate the electric heater 13 all the time, and the running cost can be reduced. Moreover, deterioration of the cooking oil due to heating by the electric heater 13 can be suppressed.

In particular, here, the oil tank 8 is provided with a viewing portion (viewing window 28) for visually observing the storage state of the cooking oil. can. Therefore, it is possible to replenish the oil tank 8 with cooking oil at an appropriate timing, and it is less likely that the replenishment of the cooking oil will be delayed and the cooking will be hindered.
In addition, since exhaust heat from the pulse combustor 3 is transferred to the oil tank 8, the exhaust heat can be effectively used to maintain the liquefaction of the cooking oil in the oil tank 8.
Further, the oil tank 8 is provided with detection means (oil level sensor 15) for detecting the storage state of the cooking oil. When it is confirmed that the oil supply is correct, the electric heater 13 is operated and the oil supply pump 14 is operated, so that the oil tank 8 is appropriately replenished with cooking oil.
In addition, when the amount of cooking oil in the oil tank 8 does not exceed a predetermined amount even after a predetermined period of time has passed since the operation of the oil supply pump 14, the controller 30 notifies that the oil container 11 is empty. , a rapid replenishment of solid oil by the cook becomes possible.

On the other hand, the controller 30 controls the pulse burner 3 with a predetermined first heat amount when the amount of cooking oil contained in the oil tank 2 is a predetermined first oil amount and the amount of food to be cooked is a predetermined first rated amount. a first cooking mode in which the food is cooked with a second cooking oil amount that is greater than the first oil amount and a predetermined second rated amount that is greater than the first rated amount of cooking oil. , a second cooking mode in which the object to be cooked is cooked by controlling the pulse combustor 3 with a predetermined second heat quantity larger than the first heat quantity, and the oil tank 8 is at least Since the difference between the first rated amount and the second rated amount of cooking oil can be stored, the cooking oil to be put into the oil tank 2 is replenished from the oil tank 8 when shifting from the first cooking mode to the second cooking mode. Therefore, it is possible to immediately shift to the second cooking mode.

In addition, in the invention relating to the oil replenishing means, the pump that supplies cooking oil from the oil container to the oil tank may be manually operated at any timing, and the oil replenishing valve may be opened/closed automatically or manually. The oil tank may be detachable.
Moreover, the visual observation part is not limited to the observation window, and a water level gauge or the like can be adopted.
Furthermore, when there are a plurality of oil tanks, each oil tank may be replenished with cooking oil from one oil tank, or an oil tank may be provided for each oil tank. The oil container is not limited to one oil tank, and may be provided for each of a plurality of oil tanks. A configuration related to filtering can also be omitted.

(Effect of the invention related to the shape of the oil tank)
According to the fryer 1 of the above-described configuration, the oil tank 2 includes the first cooking section 6 formed in a deep shape and storing the first amount of oil, and the second cooking section 6 formed above the first cooking section 6 to store the first amount of oil. The second cooking portion 7 is formed in a reverse tapered shape expanding in the circumferential direction as it goes upward from the upper end of the first cooking portion 6. As a result, it is possible to secure the volume when shifting to the second cooking mode without increasing the volume of the oil tank 2 so much. Therefore, even if cooking in both the first cooking mode and the second cooking mode is possible, an increase in the size of the oil tank 2 can be suppressed and cost increase can be suppressed, and cooking performance and maintainability are not impaired.

In particular, here, when the first rated amount of cooking oil is stored in the first cooking section 6 and the first rated amount of food is put in, the entire food is submerged in the cooking oil. , When the second rated amount of food is put in, the food is exposed above the oil surface of the cooking oil, so that the cook is notified that the wrong amount of food has been put in. can minimize work time loss.

In addition, in the invention related to the shape of the oil tank, the configuration related to the oil tank, oil container, and filtering is not essential, and the first cooking mode and the second cooking mode with different rated amounts of the food to be cooked can be executed in one oil tank. If so, the configuration of the fryer is not limited to the above configuration.
