Liquid heat-cooking device
View Patent ↗A fryer is set up in a cooking area of a restaurant or the like for use, and allows a standby temperature of cooking oil to be switched according to congestion of customers in a hall of the restaurant. The congestion of customers is evaluated by counting per unit time the count of an entrance switch when a customer enters the hall. When the count number per unit time is equal to or greater than a predetermined count, the oil temperature in a oil vessel of the fryer is set at a standby temperature T 1 (degrees Celsius) allowing food materials to be quickly heated or fried. On the other hand, if the count is smaller than p 1 times, the oil temperature is set at a standby temperature T 2 (degrees Celsius) which is lower than the standby temperature T 1 thereby conserving energy.
1. A liquid heat-cooking device comprising:
a cooking vessel that accommodates liquid;
a heating means that heats the liquid in the cooking vessel;
a temperature detecting means that detects a temperature of the liquid;
a customer-congestion detecting means that detects customer congestion in a predetermined area;
a temperature setting means that sets a standby temperature of the liquid according to a detection result of the customer-congestion detecting means; and
a heat controlling means that controls an operation of the heating means so that the liquid is at the standby temperature set by the temperature setting means, wherein
the temperature setting means,
sets a first standby temperature when the detection result of the customer-congestion detecting means indicates a value equal to or greater than a predetermined value, and
sets a second standby temperature lower than the first standby temperature when the detection result of the customer-congestion detecting means indicates a value smaller than the predetermined value.
2. The liquid heat-cooking device according to claim 1 , wherein
the customer-congestion detecting means includes a press-count calculating means that detects a press of a switch for opening and closing a door at an entrance of the predetermined area and calculates the press count per unit time, and
the temperature setting means,
sets the first standby temperature when the press count per the unit time calculated by the press-count calculating means is equal to or greater than a predetermined count, and sets the second standby temperature when the press count is smaller than the predetermined count.
3. The liquid heat-cooking device according to claim 1 , wherein
the customer-congestion detecting means includes an opening/closing-count calculating means that detects an opening/closing count of a door at an entrance of the predetermined area and calculates an opening/closing count of the door per unit time, and
the temperature setting means,
sets the first standby temperature when the opening/closing count of the door per the unit time calculated by the opening/closing-count calculating means is equal to or greater than a predetermined count, and sets the second standby temperature when the opening/closing count is smaller than the predetermined count.
4. The liquid heat-cooking device according to claim 1 , wherein
the customer-congestion detecting means includes a head-count calculating means that detects the number of people passing through an entrance of the predetermined area and calculates the number of passing people per unit time, and
the temperature setting means,
sets the first standby temperature when the number of passing people per the unit time calculated by the head-count calculating means is equal to or greater than a predetermined head count, and sets the second standby temperature when the number of passing people is smaller than the predetermined head count.
