FIG. 3 is a block diagram showing a control system of this embodiment. Reference numeral 28 denotes a control unit which includes a microcomputer 30 having a built-in memory 29, a transformer 31 and a buzzer 32.
And a power board 33 having the same. The power board 33 includes a motor 4, a compressor 7, a condenser 8, a heater 26, a temperature sensor 27, and a microcomputer 3
The microcomputer 30 is provided with an operation panel 34.

The operation panel 34 includes a menu name display panel 35 displayed by LEDs, a menu key 36 for selecting the type of ice cream to be manufactured, a start key 37 for starting cooking, and an operation stop and setting menu. It has a cancel key 38 for canceling, and a takeout key 39 which is input when taking out the material container 15 from the cooking chamber 3 when the ice cream is completed. Among them, the take-out key 39 is one of the characteristic constitutions of the present invention, and accepts an input only after the ice cream is completed, and allows the heater 26 to be energized during the input. Note that the menus exemplified in the present embodiment are not particularly limited to the number and types of the menus.

Next, a method for producing ice cream in such an ice cream production machine will be described.
The fitting portion 19 of the material container 15 is attached so as to match the fitting receiving portion 18 of the cooking chamber 3, the rotating shaft 10 is made to pass through the boss portion 17, and the stirring blade 20 is attached to the tip of the rotating shaft 10.
Milk, which is used as a material for ice cream, in a material container 15;
Set sugar, whipped cream, egg yolk, and operate panel 34
When the "Ice cream" menu is selected and the start key 37 is pressed, the microcomputer 30 reads the ice cream menu program from the memory 29 and the operation starts.

First, while rotating the stirring blade 20 at a low speed by driving the motor 4, the heater 26 is energized to stir and heat sterilize the material. (= 70 to 80 ° C.), the heater 26 is stopped, and the motor 4 is continuously rotated at a low speed to actively radiate and cool the hot air of the material. When the temperature of the cooking chamber 3 detected by the temperature sensor 27 reaches a predetermined temperature, while rotating the motor 4 at a low speed as it is,
By driving the compressor 7 and the condenser 8, the cooking chamber 3 is maintained at a freezing temperature (= −20 ° C.) and solidified as ice cream. When the end of the cooking time is detected by the timer (6), the completion of the ice cream is notified by the buzzer (7), and the operation is completed.

In the step of freezing the material, the material container 15 is cooled, and the air remaining in the gap S with the cooking chamber 3 freezes, but the flow of air is blocked by the seal member 25 provided on the upper surface of the cooking chamber. As a result, the condition of icing stops to some extent, and the material container 15 does not become unremovable.

If there is ice on the material container 15 so that the material container 15 cannot be taken out, the take-out key 39 is input. This key 39 is energized to the heater 26 only during input,
The ice can be thawed by keeping inputting until the material container 15 can be removed. Further, since the take-out key 39 accepts an input only after the completion of the ice cream, even if the input is erroneously performed during the ice cream manufacturing process, the power supply to the heater 26 can be avoided.

The structure of the take-out key 39 is as follows.
Various specifications are conceivable, such as a method in which the energization time to the heater is managed by a timer by inputting the number of times and a method in which the heater is energized until the temperature of the material container detected by the temperature sensor starts to increase.

[0020]

As described above, the present invention is constructed and provided with a seal member for preventing air from entering into the gap between the outer surface of the material container and the inner surface of the cooking chamber, so that the material container is frozen to the cooking chamber. Possibility is reduced, and the material container can be easily taken out.

Further, even if the material container is frozen in the cooking chamber, a take-out key is provided which is energized to the heater while the input is being made, so that the ice can be thawed immediately and the material container can be quickly removed. Is what you can do.
