Description

Hot and cold water dispenser}

The present invention relates to a device for dispensing drinking water, and more specifically, to improve the structure of the cold water supply system of the water distributor to increase the cooling efficiency, and to facilitate the separation and installation of the installed reservoir, so that the washing and exchange installation is easy. It relates to a cold and hot water exhauster to provide a more hygienic water supply.

Modern society enjoys the benefits of abundant material civilization with the development of industry, but due to the enormous energy consumption and use of material resources caused by industrial development, the environment of the earth is getting worse day by day, which is essential for our life. Due to the indispensable pollution of air and water, it is emerging as a serious problem that threatens human life as a whole.

Therefore, the supply of clean water, which is directly connected to our lives, is very important in protecting our lives, and the device for supplying the cleaner water has become an indispensable necessity in our lives due to the distrust of tap water. .

In general, the cold and hot water water distributor is divided into a press-type water distributor using a built-in water filter and directly connected to tap water, and a bucket-type cold / hot water water distributor using water that is sanitarily purified and supplied in a bucket of a predetermined standard. It is a useful household tool to provide drinking water more conveniently and hygienically by enabling the immediate distribution and use of cold or hot water or room temperature water.

6 is an internal configuration diagram illustrating the main components and functions of a conventional bucket cold / hot water dispenser. The main components of such a bucket water distributor are installed in a case forming a body, and supply cold water. Cold water supply system including a reservoir (2) to serve as a cold water container for the water and the hot water supply system for supplying hot water is divided into accessories.

The hot water supply system is composed of a hot water tank (3), a heater (4) for heating the water in the hot water tank (3) and a hot water temperature automatic controller (5) for automatically adjusting the temperature of the hot water.

In addition, the cold water supply system is a device for circulating the refrigerant by a conventional cooling cycle to cool the water compressor (6) for compressing the refrigerant in the gas state at high pressure; A heat dissipation plate (7) for cooling the gaseous refrigerant of the high temperature and high pressure compressed by the compressor (6) and converting it into a liquid refrigerant liquid; A dryer 8 for removing moisture and dirt contained in the refrigerant inside the pipe; A capillary tube 9 for reducing the pressure of the refrigerant liquid passing through the dryer 8 to a constant pressure; An evaporator (10) for expanding and evaporating a refrigerant having a low temperature and low pressure in a liquid state through the capillary tube (9) to absorb external heat; It consists of a suction pipe 11 for connecting the refrigerant passing through the evaporator 10 back to the compressor 6 to circulate.

Cooling water is a lower end of the reservoir (2) is heat exchanged in the state in close contact with the evaporator 10, that is, the cooling tube circulating around the integral cold water container is heat of the water contained in the reservoir This is to reduce the temperature of the water to provide the cooling water.

Reference numeral 12 is a cold water temperature automatic controller which maintains the temperature of the cooling water within a predetermined temperature range by detecting the temperature of the cooling water tank to interrupt the power of the compressor, and 13 is installed inside the water reservoir 2 to allow room temperature water. And baffle to separate the coolant from mixing with each other.

That is, the reservoir 2 is divided by the baffle 13 to form a cooling water container to maintain the temperature of the upper temperature and lower cooling water.

In the cold / hot water machine operated in such a configuration, the reservoir 2 is installed on the inner upper portion of the water distributor and supports the bucket 1 housed inverted on the upper side, the water supplied from the bucket 1 It is a part that plays a very important function of temporarily storing and cooling it or supplying it to the hot water tank (3) while maintaining an appropriate amount.

In order to maintain clean state at all times and to supply more hygienic water, the cold and hot water dispenser must periodically clean the inside of the dispenser, especially the reservoir 2.

However, in the conventional conventional cold and hot water distributor, the reservoir 2 has a fixed structure that cannot be easily separated and separated from the main body of the distributor. Particularly, the conventional evaporator 10 is formed around the reservoir 2. The wound copper tube was directly welded with the reservoir to form a fixed structure, which was virtually impossible to separate, and the user could not easily wash the inside of the reservoir, thus including various problems.

That is, the reservoir is a part in direct contact with the bucket supplied from the outside, there is a high risk of contamination due to the infiltration of foreign matters when replacing the bucket, it is pointed out as a problem in the hygienic water supply because there is no self-sterilization or cleaning function.

Therefore, in order to wash the reservoir, there was an inconvenience, such as moving the entire body of the water distributor.

As a prevailing technique for improving such a problem, a water distributor having a configuration capable of separating the reservoir as shown in FIG. 7 is proposed.

The prior art configuration is provided with a heat insulating material 21 having excellent heat insulating effect inside the main body case 20, the cooling probe 22 formed to protrude from the lower side is installed to protrude upward, the reservoir 24 is the lower side Has a projection 25 protruding into the barrel as the cooling part of the chamber is closed.

Therefore, during assembly, since the cooling probe 22 is inserted into and close to the lower side of the protrusion 25, heat exchange is performed.

However, such a conventional configuration is easy to wash or exchange installation by separating the reservoir 24 from the main body, but the material of the reservoir 24 is made of PVC material, the material having a relatively low thermal conductivity Therefore, there is a problem that the cooling efficiency is significantly lowered, and in particular, there is a problem that the heat efficiency is lowered by the heat exchange is made through the multi-step portion of the heat exchanger between the evaporator and the reservoir.

As another conventional technology proposed as a method for improving the cooling efficiency by improving this problem, the technical configuration as shown in FIG. 8 has been proposed.

That is, the bottom of the reservoir 31 is drilled so that the cylindrical cool probe 32 can be directly penetrated into the inside of the reservoir 31, and the cylindrical probe fitting 33 on the lower side of the reservoir 31 is When installed, it is mounted on the lower end of the reservoir 31 so as to be fitted into the cooling gland probe 32 to be sealedly coupled.

Inside the sealing ring 34 is fitted to prevent leakage.

However, the prior art has a problem in the sealing structure according to the installation structure of the sealing ring 34 and the change of the properties of the material of the sealing ring 34 for a long time use.

In other words, in the structure that is in direct contact with the low-temperature cooling part and is simply sealed by inserting the cooling part, there is a risk of leakage since the material cannot be completely sealed due to the separation caused by the difference in the coefficient of thermal expansion for each material. Therefore, it is raised as a fatal problem in the tank.

The present invention devised to improve such a problem proposes a new structure of the evaporator, and also the heat exchange part of the reservoir and the evaporator to make good heat exchange between the heat exchanger to facilitate the excellent heat exchange and excellent product performance and use The purpose is to provide a hot and cold water distributor that allows for more hygienic water supply.

It is to be supplied, it is to be distributed through the distribution faucet 310 by controlling the temperature with cold water and hot water, respectively, by the cooling device and the heating device installed therein.

Figure 2 is a partial cutaway showing the shape of the reservoir 200 to supply the cold water by controlling the temperature of the water contained inside by the heat exchange between the evaporator 100 and the evaporator 100 of the cooling device which is the main part of the present invention 3 is an exploded cross-sectional view illustrating an operating state of the evaporator of the present invention cooling device, FIG. 4 is a cross-sectional view of a separated state of the evaporator 100 and the reservoir 200, and FIG. 5 illustrates a combined state. It is a cross section.

In the hot and cold water dispenser of the present invention, a characteristic component of the cooling means is a cooling system 320 in which a refrigerant is circulated through heat exchange through the one-room evaporator 100 and the one-room evaporator 100 and the one-room evaporator 100. Easy to separate from the coupling and consists of a reservoir 200 to lower the temperature of the water contained in the heat exchange by direct contact.

The one-room evaporator 100 is in close contact with the bottom surface of the dome-shaped protrusion 210 of the reservoir 200, the upper outer surface is made of a dome-shaped roof 110 so that heat exchange is made, the refrigerant directly expands therein It is formed by forming a predetermined evaporation space 140 that can evaporate.

Referring to the configuration of the studio evaporator 100 in more detail, as shown in FIG. 3, the bottom surface of the flat bottom surface 130 and the reservoir 200 are easily fixed to the pedestal 340. Round dome-shaped roof 110 with excellent moldability and one-room enclosed space sealed by one cylindrical column side wall 120 to facilitate easy separation and expansion while increasing the heat exchange area. It is configured to form a one-room evaporation space 140, which is a relatively large space.

One side of the one-room evaporation space 140 is provided with a capillary tube 160 for introducing a refrigerant in a liquid state, and the other side is expanded and vaporized refrigerant is recovered again in the evaporation space 140, the cooling system 320 Suction pipe 150 is installed to lead to the compressor of the) to circulate the refrigerant.
