Description

Water purifier cooling apparatus by direct cooling

The present invention relates to a cooling device for a water purifier, and more particularly, to form a separator in which a coolant is accommodated inside the water purifier, and to install a cooling pipe between the separators to obtain a fast and large amount of cooling water (negative water) of uniform water temperature. To a chiller for a direct cooled water purifier.

As a well-known example, as shown in FIG. 1, a conventional water purifier cooling device includes a reservoir 1 having a normal inlet and an outlet, and a cooling pipe 2 installed at one side of the reservoir 1. do.

Reservoir 1 is formed of a rectangular or circular barrel to store drinking water, the water is stored in the interior (4) and the cooling pipe in which the refrigerant flows to the outside (5) bordering the partition (3) After (2) penetrates the partition wall 3, it is provided in the shape of a coil near the inside 4 of the partition wall 3 to store a relatively large amount of water, cool it, and then take out the cooling water to drink it. Is formed.

However, the first cup to be taken out due to the problem of storing a large amount of water is cooler or the last glass, or when fresh water is added, the cooling pipe 2 has to be operated again. It was difficult to obtain cold water continuously because the speed of water became high.

In addition, when a large amount of water is stored, when not used for a long period of time, germs multiply and sanitary problems and cooling pipes 2 are installed near the interior 4 of the partition 3 so that the temperature gradient As a result, a problem arises in that only water near the cooling pipe 2 is unevenly cooled.

As another well-known example, as shown in FIG. 2, a reservoir 1 capable of storing water, a cooling pipe 2 wound along an outer circumferential surface of the reservoir 1, and a reservoir 1 Installed at least one of the inner circumferential surface of the includes a temperature sensor (5) for measuring the temperature of the water stored.

This configuration is a structure in which the refrigerant flowing through the cooling pipe (6) cools the water in the reservoir (1), when the temperature of the water rises by the temperature sensor (5) flows the refrigerant through the cooling pipe (2) To lower.

However, when there is no water in the reservoir 1 or when the water purifier is not used for a long time, the refrigerant continues to flow through the cooling pipe 2 wound by the operation of the temperature sensor 5. Therefore, an ice wall is formed on the inner and outer circumferential surfaces of the reservoir 1, and the temperature sensor 5 is buried by the ice wall, and thus a compressor, which is a device for circulating the refrigerant, does not operate.

In addition, in extreme cases, the water temperature is lowered only at the side of the wound cooling pipe (2), and the water temperature at the central portion of the reservoir (1) is 15 ?? It may rise above.

In addition, there is no flow of water, the water in the reservoir (1) is only partially filled with a fatal disadvantage that can not continuously supply cold water.

In one preferred embodiment, the cooling apparatus for a direct cooled water purifier according to the present invention solves all the above-mentioned problems and provides continuously cold water.

In the cooling apparatus for a direct cooling water purifier of the present invention, a plurality of separators are provided in a reservoir, and a cooling pipe having an independent expansion valve is installed between the separators to supply a refrigerant.

Accordingly, an object of the present invention is to provide cold water, which is maintained at a constant temperature at all times, even though cold water is taken out through rapid cooling.

Another object of the present invention is to provide a small reservoir that can be mounted on the water purifier.

Still other objects and effects of the present invention will become apparent from the following detailed description.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. Briefly described with reference to the accompanying drawings, Figure 3 shows a configuration of a conventional cooling device applied to the cooling device for a direct cooling water purifier according to the present invention, Figure 4 is one of the cooling device for a direct cooling water purifier according to the present invention. 5 shows a cooling pipe applied to the cooling device for a direct cooling water purifier according to the present invention, and FIGS. 6A, B, and C show a cooling pipe applied to the cooling device for the direct cooling water purifier according to the present invention. Various applications are shown.

First, referring to FIG. 3, a conventional cooling device applied to the present invention includes a compressor 10 which compresses a refrigerant in a gas state and phase-changes it into a liquid state of high temperature and high pressure. A condenser 12 for dissipating high heat contained outside and condensing with the compressed refrigerant, an expansion valve 14 for changing the refrigerant condensed in the condenser 12 to low temperature and low pressure, and the expansion valve 14 It includes a cooling pipe 16 for cooling the stored negative water by passing through the refrigerant through.

Compressor (10) serves as a pump for sucking the low-temperature, low-pressure refrigerant vapor evaporated to facilitate evaporation, and compresses the absorbed vapor into high-temperature, high-pressure steam to easily condense and the force of compression This continually plays the role of circulating the refrigerant into the pipeline in the water purifier.

The condenser 12 cools and liquefies the refrigerant vapor compressed at high temperature and high pressure in the compressor 10 connected by a pipeline. That is, the condenser 12 serves as a kind of heat exchanger that cools the heat absorbed from the low heat source in the evaporator to discharge to the high heat source, and also liquefies the refrigerant for continuous reuse.

Expansion valve 14, commonly referred to as a pressure reducing device is provided with a plurality of high-temperature, high-pressure refrigerant liquid from the condenser 12 through the pipe, that is, through the refrigerant distribution pipe (13). The role of the expansion valve 14 is to reduce the pressure to the evaporation pressure (evaporation temperature) required in the refrigerating device and to control the flow rate of the refrigerant liquid.

4 to 6, the cooling pipe 16 connected to the expansion valve 14 to flow the refrigerant and the negative water stored therein are stored, and the cooling pipe 16 is installed and stored therein. Cooling water storage device for cooling the drinking water, and to take out the cooled drinking water.

A plurality of expansion valves 14 are coupled to each other so as to be connected to the cooling pipes 16, which are the pipelines through which the refrigerant flows, and then extend.

In this way, the extended cooling pipe 16 is arranged such that the refrigerant inlet 16a and the refrigerant outlet 16b are bent to have a constant curvature. That is, the cooling pipe 16 extending from the refrigerant inlet 16a is bent and extended to have a constant radius, and the cooling pipe 16, which is extended again, is bent to a certain radius and extended to the refrigerant collecting pipe 18. It is collected and connected to the compressor 10. On the other hand, needless to say, the cooling pipe 16 applied to the present invention is preferably applied to the material of the copper tube, the above-mentioned radius can also be variously changed at the level of those skilled in the art, the present invention also one embodiment described above Note that it is not limited to this.

Cooling water storage device 20 is provided with a plurality of partition walls (20b) are assembled to form the inner receiving space (20a) for storing the negative water.

Such, the partition wall (20b) is assembled into a constituent each piece, regardless of the shape of a rectangle or square, round, etc., assembled in a variety of shapes, there is a fluid, preferably negative water is stored therein to completely block leakage It characterized in that the sealing. In addition, pipe insertion holes 20c are formed in the upper and lower sides of the partition wall 20b in the same number as the number of the cooling pipes 16 installed so that the cooling pipes 16 are inserted, and the negative water is supplied to the side surfaces thereof. A negative water inlet 22b and a negative water outlet 22c through which the cooled negative water is taken out are formed.

In the interior assembled with the partition wall 20b, that is, the inner receiving space 20a, a plurality of separators 22 are provided to be spaced apart from each other to provide a constant water storage space.

The separation membrane 22 has a through groove 22a formed so that the bent cooling pipe 16 passes through the separation membrane 22, and its shape may be variously changed according to the shape of the inner accommodation space 20a. In one embodiment according to the invention was applied in the shape of a rectangle.

On the other hand, the separator 22 is fixed to the lower side or the upper side of the partition wall (20b). For example, when fixed downward, a predetermined flow path is opened upward so that a predetermined flow path is formed, and when fixed upward, a constant space is opened downward.

In addition, the through groove 22a may also be formed in a square or a circle, or may be applied to pass the cooling pipe 16 into an open space without forming the through groove 22a.

Therefore, the water is sealed by the partition wall 20b so that no leakage occurs, and the cooling pipe 16 and the negative water pass through the open space of the separation membrane 22 installed therein, so that a constant amount of negative water is always cooled in the cooling pipe 16. It is in contact with the structure to allow instant cooling.

Here, I want to explain the role of the solenoid valve (not shown) applied to most of the cooling system.

The role can be understood as a manual on-off valve that automatically flows and shuts off the refrigerant flow in the cooling device, which can be automatically operated on a regular basis and can be operated by simple electrical operation.

The solenoid valve may be controlled by a thermostatic switch, a float switch, a low pressure switch, a high pressure switch, or a device capable of interrupting or recognizing other electric circuits. The solenoid valve applied in the present invention is a dual temperature controlled switch. do. In addition, it is preferable to install before the expansion valve 14 as an installation place. Therefore, when the negative temperature rises above the set temperature, the refrigerant in the cooling pipe 16 automatically flows to cool the negative water.

Next, the operation of the cooling device for such a direct cooling water purifier and the effects thereof will be described in detail.

Cooling water storage device 20 is applied to the present invention is formed so that the amount of stored negative water is relatively small. In other words, preferably 2-3 cups of water is stored.

Negative water is supplied to the negative inlet 22b formed on the side surface of the cooling water storage device 20. The supplied negative water is stored between a plurality of separators 22 installed, and the negative water is cooled by the operation of the cooling pipe 16.

As described in the foregoing, since the stored negative water is 2-3 cups, it is possible to cool rapidly by the cooling pipe 16 installed in plural numbers, so that it is always maintained at a constant temperature, preferably 6 ° C.

In addition, in order to achieve a more stable temperature gradient, in the present invention, a vortex forming protrusion 22e is formed on the pin-shaped flow path control protrusion 20d and the separator 22 on one side of the partition wall 20b so that the negative flow is evenly made. To lose.

Therefore, it is possible to maintain a uniform water temperature due to an appropriate temperature gradient, to enable the discharge of a large amount of low-temperature negative water due to the instant cooling action, there is always a hygienic effect by storing only a small amount of negative water used for drinking water.

In addition, the compressor 10 operates only when the negative water is discharged by the solenoid valve, thereby saving the maintenance cost.

That is, as will be clear from the above description, the present invention provides a cooling device for a direct-cooling water purifier to instantly cool a small amount of negative water, thereby drinking a large amount of the always-cooled drinking water.

Therefore, this invention can be implemented in other various forms, without deviating from the mind or main characteristic. For this reason, the above-described embodiments are merely examples in all respects and should not be interpreted limitedly. The scope of the present invention is shown by the scope of utility model claims, and is not limited by the specification text. Again, variations and modifications belonging to the equivalent scope of the utility model claims are all within the scope of the present invention.

As described in detail above, according to the cooling device for a direct cooling water purifier according to the present invention, the negative temperature of a constant temperature is always maintained by a cooling pipe that is independently installed to store only a small amount of negative water and to quickly cool a small amount of negative water. Be sure to Therefore, it is possible to continuously take out the negative water, it is hygienic by storing only a small amount of negative water, there is an effect that the maintenance cost is reduced by the compressor that operates only when the discharge of negative water.
