That is, as shown in the illustrated embodiment it may be formed by cutting the outer edge of the end of the valve stem 230 to form a step. As such, when the area reducing part 231 is formed at one end of the valve stem 230, the contact area between the valve stem 230 and the valve body 200 may be reduced. Therefore, the valve stem 230 may move to reduce vibration and noise due to contact between the end of the valve stem 230 and the valve body 200. Accordingly, vibration and noise that may occur at the contact portion between the valve body 200 and the magnetic force generator 300 may be reduced. In this embodiment, the area reducing portion 231 is formed on the opposite side of the end of the valve stem 230 in contact with the outlet port 220 of the valve body 200. Alternatively, the area reducing unit 231 may be formed at the end of the valve stem 230 in contact with the outlet port 220 of the valve body 200.

However, the area reducing unit 231 may be in any form as long as the area of the end of the valve stem 230 and the valve body 200 can be reduced. In addition, although the area reduction part 231 is formed only at one end of the valve stem 230 in the illustrated embodiment, the area reduction part 231 may be formed at both ends.

The magnetic force generating unit 300 may be connected to the valve body 200 as shown in FIG. 2 and FIG. 3. To this end, as shown, the magnetic force generating unit 300 may have a main body insertion hole 340 into which the valve body 200 may be inserted. Then, one side of the valve body 200 inserted into the body insertion hole 340 may be connected to the magnetic force generating unit 300 by a connecting member such as a bolt as shown. However, the method of connecting the valve body 200 and the magnetic force generating unit 300 is not limited to the present embodiment and may be any method as long as the method of connecting the valve body 200 and the magnetic force generating unit 300.

The magnetic force generating unit 300 may include a coil 310, a cover 320, and a magnetic field forming plate 330 as shown in FIGS. 2 and 3. Coil 310 may be provided in the magnetic force generating unit 300 so as to wind the circumference of the valve stem 230 when the valve body 200 is inserted into the body insertion hole 340 as shown. Wires can be connected to the coil 310 as shown in the drawing so that electricity can be supplied to the coil 310 from the outside. Meanwhile, the cover 320 may cover the coil 310 as shown. In addition, the magnetic field forming plate 330 is provided at the lower end of the coil 310 as shown, when electricity is supplied to the coil 310 may form a magnetic field to generate a magnetic force.

The shock absorbing part 400 may be provided at the contact portion of the valve body 200 and the magnetic force generating part 300 as shown in FIGS. 2 and 3. As such, when the buffer unit 400 is provided at the contact portion between the valve body 200 and the magnetic force generating unit 300, the contact portion between the valve body 200 and the magnetic force generating unit 300 is moved by the movement of the valve stem 230. Vibration and noise that can occur can be reduced.

To this end, the buffer unit 400 may include a buffer member 410 and a buffer auxiliary member 420, as shown in the embodiment shown in Figs. The buffer member 410 may be provided at the contact portion of the valve body 200 and the magnetic force generating unit 300 as shown. To this end, the buffer member 410 may be formed with a body insertion hole 411 into which the valve body 200 can be inserted. On the other hand, as shown in the illustrated embodiment, the buffer member 410 may be an O-ring.

On the other hand, as shown in the illustrated buffer auxiliary member 420 may be a washer. However, the buffer auxiliary member 420 is not limited to the washer as in the present embodiment, as long as it can assist the buffer member 410 to reduce vibration and noise caused by the movement of the valve stem 230. .

Hereinafter, the operation of the defrosting solenoid valve 100 of the ice maker according to the present invention will be described in detail with reference to FIGS. 4A and 4B.

When ice making is performed in the ice maker 1 shown in FIG. 1, the outlet port 220 formed in the valve body 200 of the solenoid valve 100 is closed by the valve stem 230 as shown in FIG. 4A. . That is, since no magnetic field is formed in the magnetic field forming plate 330 because no electricity is supplied to the coil 310, the magnetic force due to the magnetic field does not act on the valve stem 230. Therefore, the valve stem 230 is lowered by the spring force of the spring 240 as shown, thereby closing the outlet port 220. Therefore, as shown in FIG. 1, the refrigerant, which has passed through the compressor 2 and has become a high temperature and high pressure, does not flow to the ice-breaking line 7 but flows to the condenser 3.

After the ice is finished, it is necessary to remove the ice generated in the ice making member 6 provided in the evaporator 5 of the ice maker 1 shown in FIG. In this case, as shown in FIG. 4B, the outlet port 220 formed in the valve body 200 of the solenoid valve 100 is opened. That is, electricity is supplied to the coil 310 to form a magnetic field on the magnetic field forming plate 330, whereby a magnetic force acts on the valve stem 230. As such, the valve stem 230 overcomes the spring force of the spring 240 by the magnetic force applied to the valve stem 230 and rises as shown in FIG. 4B. As a result, as shown in FIG. 4B, the outlet port 220 is opened, so that the refrigerant, which has passed through the compressor 2 of FIG. do. Thus, the high temperature and high pressure refrigerant which flowed through the ice-breaking line 7 passes the ice-making member 6 of the evaporator 5, and the ice produced in the ice-making member 6 melt | dissolves the contact part which contacts the ice-making member 6; . As a result, the ice is separated from the ice making member 6 and, although not shown, is dropped and stored in the ice storage.

On the other hand, the defrosting solenoid valve 100 of the ice maker according to the present invention is a buffer unit 400 including a buffer member 410 and a buffer auxiliary member 420, the valve body 200 and the magnetic force of the solenoid valve 100 It is provided in the contact part of the generation part 300. Therefore, as the valve stem 230 moves in the process of opening and closing the outlet port 220 of the valve body 200 by the valve stem 230 as described above, the valve body 200 and the magnetic force generating unit 300 Vibration and noise that may occur at the contact portion of the) may be absorbed by the buffer 400.

In addition, as the area reducing part 231 is formed at the end of the valve stem 230, the end of the valve stem 230 and the valve body due to the reduction in the contact area between the end of the valve stem 230 and the valve body 200. By reducing the vibration and noise due to the contact with the 200, it is possible to reduce the vibration and noise that may occur in the contact portion of the valve body 200 and the magnetic force generating unit (300).

As such, by the area reducing unit 231 of the buffer unit 400 and the valve stem 230, vibration and noise that may occur at the contact portion between the valve body 200 and the magnetic force generating unit 300 may be reduced. . In addition, since vibration and noise can be reduced, it is possible to smoothly flow the refrigerant flowing through the ice-breaking line 7. Then, since the flow of the refrigerant flowing through the ice-breaking line 7 can be smoothly performed, the ice-breaking operation can be performed smoothly.
