Description

Water chiller of water purifier {WATER COOLING DEVICE OF CLEAN WATER APPARATUS}

The present invention relates to a water cooler of the water purifier, and more particularly, to improve the structure in which the cooling coil and refrigeration cycle pipes built in the water storage tank are connected through the fixing member to increase water stability and to facilitate the connection work. It relates to a water chiller of the water purifier.

In general, the water purifier allows the user to drink clean drinking water by filtering foreign substances contained in the water, and the water cooling device using the cooling coil and the water heating device using the electric heater are installed.

The conventional water purifier of the water purifier includes a storage tank for storing water, a cooling coil accommodated in the storage tank to cool the water, and both ends of which extend through the upper plate of the storage tank to the outside, and both ends of the cooling coil. A fixing member for fixing to the top plate of the water storage tank is provided.

However, the conventional fixing member for firmly fixing the cooling coil to the water storage tank has a body portion 12 is formed with a female screw 15, as shown in Figure 1, the head portion formed integrally with the body portion 12 After passing through the cooling coil 8 connected to the copper pipe 7 in the lower part of the through-hole 16 of the fixing member 10 made of a (14), and the silicone resin-based sealing member 18 is provided to the cooling The coil 8 was firmly fixed to the upper plate 2 of the water storage tank, and at the same time, it was intended to prevent leakage. As a result of using the sealing member 18 provided in this way for a long time, an odor is generated, and thus, the water storage tank. There was a problem that the water stored in the water is inappropriate to drink as drinking water is lowered water stability.

As described above, the fixing member 10 of the conventional water cooling apparatus includes a plurality of sealing members 18, a pair of press-fitting sleeves 6, and rubber packings 4 attached to the fixing members 10, as described above. Since the components had to be combined, not only there was inconvenience in the connection work process, but also, there was a problem that the work time was delayed.

In addition, in the conventional water cooling device, the cooling coil has a double pipe, that is, a structure in which the inner pipe of the same material is inserted into the outer pipe of SUS material and is bent, so that the water stored in the water storage tank is cooled by indirect cooling. There is a limit to improving the cooling efficiency, and for this reason there is a problem that the power consumption increases.

Therefore, to solve the above problems, the object of the present invention is to provide a water cooling device of a water purifier that can improve the water stability by improving the structure of the fixing member to prevent the occurrence of odor in advance.

In addition, another object of the present invention is to provide a water cooling device of the water purifier that can make the connection work more easily by improving the piping connection structure of the cooling coil and the refrigeration cycle.

The storage tank 100 temporarily stores the water flowing from the outside, and the cooling coil 120 is disposed in a floating state, and thus the cooling coil 120 performs the evaporator function. The water stored in the reservoir tank 100 is cooled.

The cooling coil 120 performs the evaporator function of the refrigeration cycle as described above, and is bent spirally to increase the heat exchange efficiency. The cooling coil 120 having a spiral is made of a single pipe using a suspipe (stainless steel pipe, also known as a sus pipe) to directly exchange heat with water in the water storage tank 100. This is to avoid problems such as corrosion even in the state accommodated.

On the other hand, a predetermined portion of the cooling coil 120 to which the fixing member 130 is coupled is formed with protrusions 122 on both sides by pressing with a press (not shown) or the like, whereby the fixing member 130 is the protrusion ( 122 is secured to the top plate 102 of the water storage tank 100 without being pushed into the spiral side of the cooling coil 120.

3 and 4, the fixing member 130 is formed of a plastic injection molding and fixed to the upper plate 102 of the water storage tank 100 through the fixing nut 160. The through hole 134 is drilled in the longitudinal direction of the fixing member 130, so that the end portions 121L and 121R of the cooling coil 120 pass through the through hole 134. It extends to the outside. In addition, an installation hole 104 is drilled in the upper plate 102 of the water storage tank 100 to install the fixing member 130.
