- the microcomputer 6 reads the output voltage of the thermistor 4 and turns on the triac 93 via the gate drive circuit 7 for a certain period of time (for example, 4 seconds) when the detected temperature has cooled to, for example, about 5 ° C.
- the triac 93 turns ON, the solenoid valve 3 opens and water is poured into the ice tray.
- the microcomputer 6 detects ice making and turns on the triacs 91 and 92 via the gate drive circuit 7. Then, the electric heater 1 is heated, and the AC motor 2 is driven.
- an object of the present invention is to provide an automatic ice making device that does not perform multiple water supply to an ice making tray and that reduces the cost of a control unit without impairing the ice making ability. .
- the automatic ice making device of the present invention comprises: an ice tray; an ice sensor for detecting that ice has been generated in the ice tray; a heater for heating the ice tray to peel ice from the ice tray; Motor for rotating the discharge member for discharging the collected ice; a position detection switch for detecting the rotational position of the discharge member; an ice storage amount detection switch for detecting the amount of ice discharged from the ice tray cover; and an ice tray.
- a water supply valve for supplying water to the motor; and a controller for energizing a motor and the heater and controlling the water supply valve. Then, the controller drives the motor when the ice storage amount detection switch detects that the amount of the stored ice is equal to or less than a predetermined amount, and when the ice sensor detects that the temperature is equal to or lower than a predetermined temperature.
- FIG. 1 is a cross-sectional view of a main part of an ice making unit of an automatic ice making device according to an embodiment of the present invention.
- FIG. 2 is a block diagram of a main part of the automatic ice making device according to the embodiment.
- FIG. 3 is an operation flowchart in the embodiment.
- FIG. 4 is a block diagram of a system of a conventional automatic ice making device.
- the present invention is not limited by the embodiment.
- FIG. 1 is a cross-sectional view of a main part of an ice making unit of an automatic ice making device according to a first embodiment of the present invention
- FIG. 2 is a block diagram of a main part of the automatic ice making device of the same embodiment
- FIG. 3 is an automatic ice making of the same embodiment. It is an operation
- the ice making unit 11 includes an ice tray 12, an ice sensor 14, a heater 15, a discharge member 16, and a motor.
- the ice sensor 14 also serves as a thermistor for detecting the temperature of the ice tray.
- the heater 15 is provided at a position where the ice tray 12 can be heated in order to peel off the ice 13.
- the ice tray 12 is formed on the outer bottom portion.
- the motor 17 operates with an AC power supply.
- the motor 17 rotates the discharging member 16.
- the position detection switch 18 detects the rotation position of the discharge member 16.
- the position detection switch 18 is off at the standby position.
- the ice storage amount detection switch 19 detects that a predetermined amount or more of ice has been stored in an ice storage box (not shown) below the ice tray 12.
- the water supply valve 20 operates by alternating current and opens and closes a water supply path.
- the heater 15 and the motor 17 are supplied with electric power via a first relay switch 22.
- the water supply valve 20 is supplied with power via the second relay switch 23.
- the controller 21 controls ON / OFF of the first relay switch 22 and the second relay switch 23 according to a signal from the ice sensor 14.
- the fuse 24 is activated when the ice tray is overheated.
- Guide plate 25 slides the ice and makes an ice tray 1
- step 1 When the controller 21 detects in step 1 that the ice storage amount detection switch 19 is in the off state, the controller 21 reads the output voltage of the ice sensor 14 in step 2. In step 2, when the detected temperature T becomes 9 ° C. or less, the controller 21 turns on the first relay switch 22 in step 3.
- the temperature of the ice tray 12 has been raised by the heater 15, and the ice in the portion in contact with the ice tray 12 has begun to melt. Therefore, the ice 13 is easily separated from the ice tray 12.
- step 4 the controller 21 reads the output voltage of the ice sensor 14, and when the detected temperature T becomes 10 ° C or more, in step 5, the first relay switch 22 is turned off and the heater 15 Turn off the power. Then, proceed to step 6 to start time measurement by the first timer.
- step 7 when the time period of the first timer has elapsed for 2 minutes or more, the process proceeds to step 8, in which the second relay switch 23 is turned on, the water supply knob 20 is driven, the water supply path is opened, and the ice making tray 12 is opened. Start water supply to. Then, the process proceeds to step 9, and the second timer starts counting time.
- step 10 when the time period S2 of the second timer has passed 5 seconds, the process proceeds to step 11, and the second relay switch 23 is turned off. Therefore, the controller 21 drives the water supply valve 20 for only 5 seconds to supply water to the ice tray.
- One cycle of the ice making operation is completed by the above series of operations. By repeating this cycle, the ice box is filled with ice.
- the ice storage amount detection switch 19 is turned on, so that the process stands by in step 1 and the ice making is interrupted.
- step 2 it waits until the temperature T detected by the ice sensor 14 becomes ⁇ 9 ° C. or less. That is, the ice is reliably produced, the ice 13 is discharged, and the power is also supplied, so that the water is not supplied twice. This eliminates the problem that water overflows from the ice tray 12.
- the stop of the motor 17 is performed by the position detection switch 18, a drive circuit for driving the motor 17 in the controller 21 is not required. Further, since the controller 21 has a simple configuration that only controls the first relay switch 22 and the second relay switch 23, the cost can be reduced.
- the automatic ice making device of the present invention can realize a series of ice making cycles with a simple configuration, it can be applied as a low-cost and highly reliable automatic ice making device for refrigerators.
