The present invention relates to an automatic ice maker attached to the refrigerator of the present invention. In particular, the automatic ice maker can be detachably attached to the refrigerator to utilize the internal space efficiently and to improve the operation system structure of the ice maker to perform a smooth ice making function. It relates to an automatic ice maker detachable to.

In the conventional case, an automatic ice maker mounted on the refrigerator is fixedly installed in the refrigerator's refrigerating compartment. When the ice making is completed, the automatic ice maker is applied to power the heater to separate the iced ice. As the ice maker occupies the limited internal space of, there is a problem such that the available internal space is reduced by that much, and there are various defects such as the power consumption is increased by the separation of the ice by the heater.

Therefore, the present invention allows the detachment of the defects of the thermo case and the ice making means to be selectively detached as necessary in order to solve the conventional drawback as described above, and also to improve the ice making (ice separation) means and the water supply driving means of the ice maker. When described in detail the configuration and operation effect by the accompanying drawings as designed to perform the operation smoothly as follows.

In the refrigerator (A) with an automatic ice maker (1) equipped with an ice maker (1) which performs an ice-making function while the ice making water collected by a predetermined water supply means is supplied to the ice tray (3) along the water supply hose (20) by the pump motor (M). , Protruding the support jaw 4a into the thermo case 4, and forming a fixing groove 1a and a fixing piece 1b in the ice maker, coupling the fixing groove to the supporting jaw, and fixing the fixing piece to the thermo case 4. Bolts to the icemaker 1 to be detachably coupled to the icemaker motor on the plate of the icemaker 1, transfer members A, B, C, D, (6, 6 ', 6 ", 6'). &Quot;) and the cam cap 8, in which the driving cap 7 is attached, are fixed to be interlocked so that the power of the moving motor is transmitted to the cam gear through the transmission members A, B, C, and D to operate the driving cam. Link device 9 made of links A and B (9a, 9b) is moved to shaft 9c while mounting water supply switch S6 and natural moving switch S2 in the up and down position in contact with drive cam 7. Fixed and the linkage Water supply prevention switch (S5) and the moving motor reverse rotation switch (S7) stacked up and down so as to be interlocked by (9), and the water supply switch (S6) and natural moving switch (S2), link by the rotation of the drive cam. The device 9 is operated and at the same time, the water supply prevention switch and the moving motor reverse switch are operated, and the manbeam (storage container full of ice) detection switch (S3) and the ice storage container departure detection switch (S1) are moved up and down. And a forced jaw switch S4 and a pressing piece 10 connected to the right side, while a fixing jaw 11a and a support hole 11b are formed on the upper side and the side, and a freezer shelf supporting guide 11c is formed. The support shelf 11 is detachably assembled to the thermo case 4 using the support jaw and the support hole, while the heat insulating material 13 is sealed on the outer periphery of the water supply hose 2 on which the heater 12 is wound. 14) is formed by foaming the foam liquid 15 in the description 16 Freezing compartment, 17 is a cooling air take-out cover, 18 is an ice storage container, the sensor arm 19, the lever 20 is a maker, 21 is a freezer shelf S8 is water detection switch, 22 is a fixing piece, 23 is a guide groove.

Referring to the effect of the present invention configured as described above are as follows.

The ice making water collected by the predetermined water supply means is supplied to the freezing chamber 16 through the water supply hose 20 by the pump motor M1. In this process, the heater 12 and the heat insulating material are formed on the outer periphery of the water supply hose 2. Since 13) is laid and the foaming liquid 15 is foamed in the case 14, the freezing of the ice-making water supplied to the freezing chamber 16 can be prevented.

In this way, the ice making water supplied to the freezing chamber 16 is supplied to the ice making plate 3 of the ice maker 1 and is formed of ice by cold air introduced through the cold air extracting cover 17.

When the ice making is completed as described above, when the ice making sensor (TRS) installed on the bottom surface of the ice making plate (3) reaches a temperature of minus -120 ° C, which is an operating sensing temperature range, the moving motor (5) passes through the predetermined reed switch contact. The power is supplied to) to automatically perform the ice breaking operation.

That is, as shown in FIG. 4, the driving force of the moving motor 5 is the cam gear 8 through the transmission members A, B, C, and D (6, 6 ', 6 ", 6'") made of gears. As shown in FIG. 6 of FIG. 6, which is attached to the cam gear 8, the link of the link device 9 built on the left side of the drive cam 7 is rotated by a predetermined distance. As one side of the A (9a) is moved while moving in the direction of the arrow X, the other side (part connected with the link B) of the link A 9a is moved along the guide groove 23 in the direction of the arrow Y around the axis 9c. Link B (9b) is interlocked and simultaneously press the button of the water supply prevention switch (S5) and the moving motor reverse rotation switch (S7).

At this time, the contact points held by the buttons of the water supply prevention switch (S5) and the moving motor reverse rotation switch (S7) installed to be stacked up and down are reversed (water supply prevention switch; NC-NO, and the moving motor reverse rotation switch NC-NO). The interlocked ice separates the ice formed in the ice tray 3, and the separated ice is loaded into the ice storage vessel 18, and the ice motor 5 is inverted to its original state according to the operation state of the ice motor reverse rotation switch S7. At the same time, as the driving cam 7 is reversed, the water supply switch S6 which is turned off is turned on (NO-NC) by the driving cam 7 so that the water supply pump M1 and the water supply detection switch S8 are turned on. In operation, the ice-making water is re-supplied to the ice-making dish through the water supply hose 2 for a predetermined time.

At this time, when the water supply switch S6 is turned off by the drive cam 7 again, the water supply pump motor M1 is stopped to stop the ice-making water supply and simultaneously switch the contact point of the natural moving switch S2 to NO-NC. As a result, the operation of the ice motor is stopped, and ice is formed by cold air introduced through the cold air extraction cover 17 as described above.

On the other hand, when the automatic deicing (freezing and ice) as described above is continuously repeated, a certain amount of ice is loaded in the ice storage vessel 18 is detected by the ice maker lever 20 connected to the arm sensor 19, the ice detection switch (S3) is switched to NO-NC to stop the operation of the ice maker (1).

In addition, when the ice storage bowl 18 is separated, the storage bowl is turned on by the arm sensor 19 connected to the fixing piece 22, so that the de-sense switch S1 is turned on to block the operation of the ice maker. When the storage vessel is removed, the ice maker is operated, that is, it is performed at the time of automatic defrosting to solve the problem of falling of the ice on the bottom of the freezer. Also, by installing the forced ice switch (S4) and the pressing piece (10) on the ice maker (1) While the operation state of the apparatus can be checked, the assembling structure of the ice maker having the above operation state is coupled with the fixing groove 1a of the ice maker 1 to the supporting jaw 4a of the thermostat 4. Since the fixing piece 1b is bolted to the thermo case 4, the ice maker 1 can be selectively detached as necessary, and the fixing jaw 11a having the guide 11c for supporting the freezer shelf 21 and the supporting jaw 11a are supported. Using the hole 11b to the thermo case 4 Stylized deionized allow assembly can be separated when not in use, the ice maker (1) from the freezer compartment 16 of the refrigerator (A) may be an inner space of the freezing chamber 16, more effectively.

As can be seen from the above, in the present invention, the ice maker 1 and the support shelf 11 are detachably attached to the thermo case 4 of the freezer compartment 16 so that the internal space can be used more efficiently. It is designed to smoothly perform automatic deicing action by improving the system structure such as ice removal and water supply driving means.
