Description

Bottled Water Station with Removable Reservoir

The present invention relates to a bucket-type water distributor in the form of supplying water while supporting and supporting the bucket upside down, more specifically, to wash and replace the installation to facilitate the separation and installation of the reservoir installed in the water distributor The present invention relates to a bucket type water dispenser having a separable reservoir for maximizing the cooling efficiency of the water as well as providing more hygienic water supply.

Bucket type water dispenser is a useful living tool that can be conveniently used by distributing the water supplied in a bucket of a predetermined standard hygienically purified water, cold water or hot water or room temperature.

7 is an internal configuration diagram illustrating the main components and functions of a conventional bucket-type cold / hot water dispenser. The main component of such a bucket-type dispenser includes a cold water container installed inside a case forming a body. It is roughly divided into a reservoir (2), a cold water supply system for supplying cold water, and an accessory device for a hot water supply system for supplying hot water.

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 cooling water by circulating the refrigerant by a conventional cooling cycle as a 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) to convert 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 which expands and evaporates a refrigerant having a low temperature and low pressure liquid state through the capillary tube 9 to absorb external heat; The refrigerant passing through the evaporator 10 is connected to the compressor (6) is composed of a connecting pipe 11 to be circulated.

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 lower cooling water tank.

In the cold / hot water machine having 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, and maintains an appropriate amount of water supplied from the bucket 1. While temporarily storing and cooling or supplying the hot water tank (3) is a very important function.

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

By the way, in the conventional conventional cold and hot water distributor, the reservoir is made of a fixed state structure that can not be easily separated and separated from the main body of the distributor, so that the user can not easily wash the interior, and thus contains 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.

In order to improve this problem, a water distributor having a configuration capable of separating the reservoir as shown in FIG. 8 is proposed.

According to the prior art configuration, the cooling probe 22 formed to protrude from the lower side is installed to protrude upward from the heat insulating material 21 having excellent heat insulation inside the main body case 20.

The reservoir 24 has a protrusion 25 protruding into the barrel in a state where the cooling portion on the lower side 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 was a problem that the cooling efficiency is significantly reduced.

As another conventional technique, the configuration shown in FIG. 9 has been proposed.

That is, the bottom of the reservoir 31 is drilled so that the cylindrical cold probe 32 is directly penetrated into the inside of the reservoir 31, and the cylindrical probe fitting 33 at 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.

The sealing ring 33 is fitted to the inside thereof to prevent leakage.

However, the prior art has a problem in the sealing function according to the structure of the sealing ring installation and the characteristics of the material of the sealing ring 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 sliding insertion into 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. Therefore, it poses a fatal problem in the tank.

In order to improve the above problems, in the present invention, by easily separating the reservoir installed in the water distributor, making the washing and exchange easy to install and excellent in sealing function, and providing the water more hygienically and the reservoir It is an object of the present invention to provide a bucket-type water distributor having a separable reservoir to maximize the cooling efficiency of the water by direct contact cooling method while producing a plastic injection molding.
