The present invention relates to an ice-making state detection device of an ice maker, and in particular, by using a detection device mounted on the bottom of the ice-making bowl, the ice-making is completed while the ice-driving means are activated by the sensing device to detect the ice-making machine. Relates to a device.

Conventionally, in the ice maker, the ice maker does not have an ice state detecting device which detects the ice state of frozen ice in the ice tray, so that the consumer operates the ice driving means to ice the ice of the ice tray, so it is inconvenient to use. There were flaws such as failure to meet the expectations of the detainees.

Therefore, the present invention has been installed to install the ice-making state detection device in the lower part of the ice tray of the ice maker to solve the above-mentioned drawback to detect the ice-making state while operating the ice-driving means means to ice the ice Referring to the configuration and operation effects in detail as follows.

In the overall structure of the ice maker 1 for twisting the ice tray 2 to ice the ice tray 2, the ice tray 2 is provided on the rotating shaft 3 of the ice driving device (not shown) mounted in the main body of the ice maker 1. ), And the other side is fixed to the guide (4a) of the heat transfer control protective plate (4) bolted to the main body fixing portion (1a) of the ice maker (1) by the operation of the ice making device (2) The sensing part connected to the ice driving device is composed of a reed switch 6, a thermal element 7, a magnet 8, and a resistor 9 in the groove 5a of the body 5, such as silicone rubber. (10) An ice making state sensing device (X) formed by hardening a material (AL, etc.) having good thermal conductivity (11, etc.) surrounding the groove (10) and the inside of the groove (5a) and the protector (11) by integrating and hardening it integrally. ) Is bolted to the lower part of the ice making bowl (2) by using a heat insulating material (12) and a fixing plate (13), which are fixing and heat insulating means. The sex, reference numeral 14 is a wire, 15 is a silicon tube.

Here, the ON time of the sensing unit 10 which is the ice making state detecting device X is -10 ° C, and the OFF time is + 40 ° C. In addition, the thermal light of the reed switch 6 is a material in which the magnetic flux density decreases when the temperature rises and, on the contrary, the saturation magnetic flux density increases when the temperature decreases.

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

Guide of soft cut control protective plate 4, in which a rotating shaft 3 of an ice driving device (not shown in the drawing) mounted in the main body of the ice maker 1 and a fixing part 1a of the main body of the ice maker 1 are bolted. In the ice maker 1 in which both sides of the ice maker 2 are fixed to 4a and ice is separated by the operation of the ice maker, the ice maker and the wires are formed on the lower surface of the ice maker 2 of the ice maker 1. 14 is a defrosting detection device (X) in which the protection device for preventing damage to parts (11, etc.) made of a material (AL, etc.) connected to the detection unit (10) connected to the inside is protected and grooved (5a) of the object (5) ) Is bolted to the insulator 12 and the fixing plate 13 so that when ice making is completed in the ice making bowl 2 of the ice maker 1 by a predetermined refrigerant cycle (temperature around the ice making vessel is about -10 ° C.) The temperature sensing element 7 of the sensing unit 10, which is the sensing device X, senses this and at the same time the thermal light of the THERMALITE in the center of the reed switch 6 is detected. When the speaker flux density reaches the maximum value, the magnet switch (8) installed on both sides of the reed switch (6) is connected between the reed switch contact points (closed circuit), and the reed switch (6) is turned on so that the silicon tube (15) The ice wire driving device of the ice maker 1 operates the electric wire 14 installed in the ice maker 1. When the ice driving device is operated in this way, one side is fixed to the rotating shaft 3 attached to the ice driving device, and the other side is a guide 4a of the protection plate member 4 for heat transfer control bolted to the main body fixing device 1a of the ice maker. The ice is iced while twisting by the rotation of the ice tray 2 fixed to it. At the same time as the ice is iced, a low source is applied to the resistance 9 in the sensing unit 10 to generate heat (at this time, if the resistance is not driven, the contact point of the reed switch 6 does not rise to a temperature where the contact point of the reed switch 6 falls (+ 4 ° C). The thermal light of the lead switch 6 is heated to reduce the density of inclusion flux. When the saturation magnetic flux density is reduced as described above, the reed switch 6 is turned off and maintained in the off state until it reaches -10 ° C again. At the same time as the above-described reed switch is turned off, the driving of the resistor 9 is stopped.

Here, the sensing unit 10 is wrapped in a protective device 11 made of a material having good thermal conductivity such as AL, so that when the ice tray is twisted, the sensing unit 10, such as the thermo sensor 7, the magnet 8, the resistance 9, It can prevent damage, and also the ice making state detection device (X) is attached to the lower surface of the ice making bowl (2) by using the heat insulating material (12) and the fixing plate 13, the ice making state detection device (X) due to deformation of the warpage, etc. Since it is possible to prevent the departure and deformation of) and not directly affected by the temperature change of the freezer compartment, that is, it is not affected by heat transfer, and thus the operating state of the sensing unit 10 is accurately performed.

As seen from the above, the present invention, while the sensing unit 10 is protected by the protective device 11 on the lower surface of the ice making bowl 2, the ice-making state detecting device X built as a heat insulating material 12 and the fixing plate 13. Since it is a fixed structure, the assembling structure is simple as well as the ice driving device is operated by the sensing means, so that the ice is made, which is a very practical design that improves the reliability and convenience of the device.
