The following describes the control procedure of ice machine fan action of the present invention: Fig. 7 is the fan control action flow chart of ice machine of the present invention.Ice machine of the present invention is supplying water, and ice making moves ice, and in the middle of the circulation of full ice action, only the ON/OFF action of primary air fan is carried out in control.And, only when carrying out ice making action, drive fan.
Under the state of supply water, control part sends command signal and gives fan electromotor drive division 330 in ice-making tray 45, makes the fan electromotor (the 220th stage) of fan electromotor drive division 330 drive fan case apparatus 80 inside.Under the control action in the 220th stage, fan electromotor drive division 330 provides power supply to fan electromotor, and therefore, the motor of fan case device 80 inside begins to drive.
When fan electromotor began to drive, the cold air of refrigerator inside supplied to cold air stream 64f by suction inlet 72.Be drawn into the cold air of cold air stream 64f inside, flow to passing away road 66 by fan case device 80.Cold air through passing away road 66 passes through outlet 68 once more, supplies to the bottom of ice-making tray 45.
By said process, supply with ice-making tray 45 cold air rapidly, the water that is contained in the inside becomes ice cube.On the one hand, in the time of the driving of control part 320 control fan case devices 80, change by temperature-detecting device 300 detected temperatures.
Temperature-detecting device 300 detects ice-making tray 45 temperature inside and changes in ice-making tray 45 1 sides.Specifically, detect the water that is contained in ice-making tray 45 and whether become ice fully.That is, when the water that is contained in ice-making tray 45 inside was formed ice cube, the temperature of ice-making tray dropped to below the uniform temperature x.So control part 54 confirms whether the temperature that detects by temperature-detecting device 300 drops to (the 203rd stage) below the uniform temperature x.
Satisfied for the 203rd stage condition the time, control part 54 judges that ice makings finish.So judging does not need cool-air feed once more.Control part 54 just stops the driving (the 206th stage) of fan case device 80 by fan electromotor drive division 330.
Through the 206th stage, stop after the fan case device 80, the ice that moves that control part 54 is just controlled the ice cube of ice-making tray 45 inside moves (the 209th stage).At first, control part 54 provides power supply and driving for heater 90 by heater-driven portion 360.Because in ice-making process, ice cube is attached to ice-making tray 45 the insides, and air-heater 90 just slightly melts away the bottom of ice cube.
The ice that moves of finishing for the 209th stage moves, and control part 54 drives feed water valves by feed water valve drive division 340, supplies with water (the 212nd stage) for ice-making tray 45.Judge by testing the ice bar whether the amount of the ice that produces reaches full ice state (the 215th stage).The 212nd stage and the 215th stage almost carry out simultaneously.
In the 215th stage, when the amount of ice making reaches full ice state, no longer carry out the ice making action.That is, the hypomere of ice-making tray 45 is provided with the container of keeping ice cube in addition, and above-mentioned full ice state just is meant and guarantees that ice cube fills the state in container.If when producing ice cube once more under full ice state, receptacle does not have enough container splendid attire ice cubes.
Therefore, the 215th stage was before full ice state is removed, and did not carry out any freezing, and moved ice, the holding state of the action of supplying water.The user takes out ice cube, and when completely the ice state was removed, control part 54 just returned to for the 200th stage, carried out above-mentioned action repeatedly.
Through the 212nd stage, water has been supplied in ice-making tray 45 the insides, and fan case device 80 carries out the ice making action when driving once more, finishes the ice making action and just moves along with moving ice.
The present invention moves ice carrying out an ice making, supplies water, and completely ices in the middle of the circulation of sensed activation, only drives the ON/OFF action of primary air fan case apparatus 80.Particularly, 80 in fan case device drives when carrying out the ice making action, prevents that fan case device 80 from carrying out action unnecessary at other course of action.Therefore, the present invention only carries out the primary air fan device and reduces action unnecessary in the middle of a circulation.
In the middle of embodiments of the invention, when ice machine drove at first, the user must supply with water to ice-making tray 45.This is because the present invention supplies water to move and carries out after ice making and moving the ice action.But, carry out first time ice making, move after the ice action, automatically perform water supply action according to the 212nd stage.
