As shown in FIGS. 1 to 4, the anti-freeze type washing machine 100 according to an embodiment of the present invention includes a body 110, an upper cap 120, a lower cap 130, (140), a piston (150), and a plurality of fastening screw rods (160).

The body 110 has a structure in which the upper and lower portions thereof are open and cylindrical and made of a transparent material. The body 110 may be made of a transparent acrylic material capable of visually confirming the amount of water introduced and collected from the fluid reservoir storing the oil.

The upper cap 120 is a disc-shaped structure that is fastened and fixed in such a manner that one side of the body of the body 110 is hermetically covered. The upper cap 120 may further include an upper valve 121 connected to the center of the disk. Here, the upper valve 121 connected to the upper cap 120 may be connected to a lower floor of a fluid reservoir for storing oil into which moisture is introduced. The upper cap 120 may be made of aluminum, and may be anodized as a surface treatment for hardness and corrosion prevention.

The lower cap 130 has a disk shape corresponding to the upper cap 120 and is fastened and fixed in a form of hermetically covering the other open side of the body 110. [ The lower cap 130 is connected to the piston rod 151 and further connected to a drain valve 131 for discharging moisture collected in the body 110. Here, the lower cap 130 is made of aluminum, and can be surface-treated by anodizing as a surface treatment for hardness and corrosion prevention. Further, in order to prevent the piston rod tube 151 connected to the lower cap 130 from shaking, the inner diameter of the piston rod on the piston rod side is reduced to improve the clearance.

The compression spring 140 is a structure of a spring disposed in the lower cap 130 in a state of being housed in the body 110. The compression spring 140 normally supports the piston 150, which will be described later, with the tension of the spring. When the ice is frozen, the compression spring 140 plays the role of returning the piston 150, which is expanded and pushed, back to its original state. Here, the compression spring 140 maintains the air flow passage on the lower side so as not to affect the squeezing of the air when the piston 150 moves.

The piston 150 has a structure in which a piston rod 151 formed through the center of the lower cap 130 is connected to the center and is disposed in contact with the upper portion of the compression spring 140. The piston 150 may have a double-disc structure in which an O-ring 152 is formed at the center of the piston 150 to prevent leakage of moisture trapped in the body 110. In addition, a detent ring 153 is formed on the upper surface of the double-type disk structure so that the double-type disk structure can be easily assembled. That is, it is possible to improve the assemblability of the piston 150 of the dual type disc structure. An inner magnet 154 protruding from one side of the upper surface of the piston 150 of the dual type disk structure is formed. The inner magnet 154 has an inherent function of magnetic component, And collects the iron component contained in the water introduced from the fluid storage tank storing the iron component. Here, the piston 150 may be made of an aluminum material, and may be surface-treated by anodizing as a surface treatment for hardness and corrosion prevention.

The plurality of fastening screw rods 160 is a fastening structure for firmly fastening and fixing the upper and lower caps 120 and 130 to each other. As shown in FIG. 3, the plurality of tightening screw rods 160 connect and fasten the upper and lower caps 120 and 120 to each other, And a fastening structure that is threaded on the inner surface of the upper cap 120 through the lower portion of the cap 130. [ In the present invention, four fastening screw rods 160 are formed as an example in which the fastening screw rods 160 surround the body 110.

FIG. 5 is a diagram illustrating a procedure of a freeze test of a freeze prevention type walker according to an embodiment of the present invention. As shown in the left side of FIG. 5, when the freeze prevention type washing machine 100 according to the present invention is filled with water (fresh water) and then stored in the freezer, one day passes, As a result, there was no external breakage, and it was confirmed that the piston 150 was pushed about 10 mm. The anti-freeze type washing machine 100 according to the present invention is an example of a size of Ø84 × 103.5H (excluding the valve and the relative assembly part), an inner volume of 94 ml, a freezing prevention volume of 24 ml 13 mm), it was confirmed that the expansion volume was expanded by 19 ml (about 20% expansion).

FIG. 6 is a view illustrating a defrosting test process of the anti-freeze type walk dog according to an embodiment of the present invention. As shown in FIG. 6, as the defrosting progresses, the piston 150 is gradually raised, there is no further movement in the last section, and the force is forced to move by hand but not moved. (Volume: 3 ml), and the upper valve 121 was opened. 6, it was confirmed that the body body 110 was widened by about 1.5 mm (3 ml), and it was confirmed that there was no problem in breakage at the time of thawing.

The present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics and scope of the invention.
