Abstract
The present invention for controlling an inflow time schedule of an ice machine includes a water inflow mechanism and a water amount control switch. The ice machine further includes a control axle, and the movement stroke of the control axle includes at least a closing locus linked to the water amount control switch for letting the water inflow mechanism to stop water inflow, and at least two opening loci which are located in the pathway of the closing locus and are linked to the water amount control switch for letting the water inflow mechanism to start water inflow. Since one closing locus is located between two opening loci, the water inflow of the water inflow mechanism will be separated into at least two times, so as to achieve a sectional water supplying effect, thereby reducing the wave motion of water in the ice tray and providing a smooth water supply.
Description
- The present invention is related to a water inflow control structure of an ice machine, and more particularly to a control structure for controlling water inflow amount and inflow time schedule of an ice machine.
- Ice machine is commonly used by restaurants or the general domestic refrigerators. Generally, the ice machine at least has an ice tray and a water inflow mechanism, wherein the water inflow mechanism is connected to a water source for proving water to the ice tray, then the water in the ice tray waits for being frozen, and the ice cubes are removed for repeating the ice making process. There are many water supplying manners for the water inflow mechanism. For example, R.O.C. Patent No. I277715, entitled “Automatic ice making device and refrigerator with thereof”, includes an ice tray and a water storage tank, and also a water pump for providing the water in the water-storage tank to the ice tray. The action of the water pump is controlled by a sensor, which is used to detect the position of the ice tray. But, this patent does not provide the method and structure for controlling water supply, so that the water supply is completed by batch. Another example of R.O.C. Patent No. I274133, entitled “Refrigerator” includes a water supplying tank, an ice tray and a water supplying machine, whose driving time is set by the user. Through altering the duration for supplying water, the water supplying amount can be altered. However, the water supplying is also completed by batch. Further, because the water supplying amount is larger and the flowing speed is faster, the wave motion of the water surface might be bigger, so that the detecting signal might have error, and thus, the water inflow mechanism might also have erroneous action, thereby occurring the problem of insufficient or excess water amount. Therefore, there is the need to improve thereof.
- Consequently, the object of the present invention is to provide a water supplying mechanism capable of smoothly supplying water, so as to avoid the water surface from waving too much as supplying water.
- The present invention provides a water inflow control structure of an ice machine for controlling the inflow time schedule of the ice machine. The ice machine includes a water inflow mechanism and a water amount control switch for controlling an inflow time schedule of the water inflow mechanism. The ice machine further includes a control axle, and the movement stroke of the control axle includes at least a closing locus which is linked to the water amount control switch for letting the water inflow mechanism to stop water inflow, and at least two opening loci which are located in the pathway of the closing locus and are linked to the water amount control switch for letting the water inflow mechanism to start water inflow. Since one closing locus is located between two opening loci, the water inflow of the water inflow mechanism will be separated into at least two times, so as to achieve a sectional water supplying effect, thereby reducing the wave motion of water in the ice tray and providing a smooth water supply.
- The foregoing aspects and many of the attendant advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

Thecontrol system 1 can set to have an ice making procedure, wherein the water in the ice tray 4 waits for being frozen, the drivingmotor 3 drives the driving gear set 31 to rotate theice sweep shaft 5 for removing theice cubes 9 in theice tray 4, and thewater inflow mechanism 6 re-supplies water to the ice tray for repeating the ice making process. The ice machine further includes a wateramount control switch 2, which has abutton 21 for controlling thewater inflow mechanism 6 to be open or close. The wateramount control switch 2 is connected to thecontrol axle 7. Thecontrol axle 7 has a movement stroke including at least aclosing locus 71 and at least twoopening loci 72, wherein theclosing locus 71 is linked to the wateramount control switch 2 for letting thewater inflow mechanism 6 to stop water inflow, and theopening loci 72 are located in the pathway of the closing locus and are linked to the wateramount control switch 2 for letting thewater inflow mechanism 6 to start water inflow. Through the drivingmotor 3 driving thecontrol axle 7 to rotate, thecontrol axle 7 can have a linkage with the wateramount control switch 2 for deciding the time schedule of water inflow, so as to control the water inflow mechanism to start or stop water supplying. Furthermore, thecontrol axle 7 is linked with the ice sweepingshaft 5, or thecontrol axle 7 can be connected with the ice sweepingshaft 5 for simplifying the driving process and also achieving a synchronization effect. - Please refer to

Following the actions of thecontrol axle 7, theclosing locus 71 will reject to thebutton 21 of the wateramount control switch 2, so that the water inflow mechanism stops the water inflow. Continuously, thecontrol axle 7 moves to force theopening locus 72 to move to thebutton 21, and at this time, compared with theclosing locus 71, theopening locus 72 gives a releasing space to thebutton 21, so that the wateramount control switch 2 makes thewater inflow mechanism 6 to start water supplying. Furthermore, following the rotation of thecontrol axle 7, theclosing locus 71 between twoopening loci 72 again forces thewater inflow mechanism 6 to stop water supplying, and then, the anotheropening locus 72 will continuously release thebutton 21 so as to make thewater inflow mechanism 6 to start water supplying. Therefore, a sectional water supplying mode is formed. Here, the number of theopening locus 72 is not limited and can be adjusted according to practical demands. Moreover, the wateramount control switch 2 also can have multiple water amount control positions, so that, between the totally open position and the close position, a partial amount position for water supplying can be formed. For matching to the wateramount control switch 2 with the multiple water amount control positions, thecontrol axle 7 can further include at least atransitional locus 74 connected between theclosing locus 71 and theopening locus 72, so that theclosing locus 71 and theopening locus 72 can be smoothly connected and thetransitional locus 74 can let thewater control switch 2 to locate at a position to provide less amount of water. - Please refer
