BACKGROUND OF THE INVENTION Field of the Invention
The present invention relates to an electric cold and hot water dispenser, and more particularly, to an electric cold and hot water dispenser with a detachable cold water reservoir, in which a conventional cold water reservoir constructed to have cold and hot water pipes connected therewith and to have a refrigerant circulation coil constructed in an integral type therewith is easily separated for easy washing, in which washing and cleaning can be provided by oneself so as to, at all times, provide a clean spring water for drinkables, and in which an effective sanitary management can be made and a cost reduction can be effected.
Description of the Related Art
As an urbanization and industrialization is gradually developed, an environmental contamination is problematically appeared, and as a modern person's life is abundant, cleanness and health are highlighted as high concerns. Accordingly, a water-purifying apparatus and the like for purifying service water for drinkables have been increasingly popularized.
Recently, spring water is provided in such a manner that after a relatively good quality of water is gathered from a nature so as to be stored in a predetermined airtight tank and be supplied for each of consuming houses within a predetermined distribution time limit.
Such spring water is provided in an electric cold and hot water dispenser installed for a user's easy manipulation, in such a manner that water supplied from a spring water reservoir can be rapidly cooled or heated so as to provide the cooled or heated spring water. FIG. 1 is a perspective view illustrating a conventional integral type of an electric cold and hot water dispenser.

Herein, the hot water pipe 16 represents all pipes connected until the hot water is provided from the hot water reservoir connection pipe 13 and the hot water reservoir 15, and the cold water pipe 14 also represents all pipes connected until the cold water is provided.
Specifically, the conventional electric cold and hot dispenser 10 has drawbacks in which, since the cold water reservoir 11 has the refrigerant circulation coil 12 welded thereto, it cannot be separated from the cold and hot water dispenser 10, and in which since the cold water reservoir 11 is connected integrally with the hot water reservoir connection pipe 13 and the cold water pipe 14, a possible careless sanitation management can result in a problematic insanitation caused by bacterium, etc.
Further, the conventional electric cold and hot dispenser has a drawback in which, at the time of washing the cold water reservoir 11 or connection valves of the hot water pipe 16 and the cold water pipe 14, a regular washing service should be requested, and accordingly washing service times is relatively rare in comparison with personal washing times thereby resulting in a more critical problematic insanitation.
Furthermore, the conventional electric cold and hot dispenser has a drawback in which a cost burden is caused by a washing service request.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to an electric cold and hot water dispenser with a detachable cold water reservoir that substantially obviates one or more problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide an electric cold and hot water dispenser with a detachable cold water reservoir, in which the cold water reservoir is constructed to have a refrigerant circulation coil separated therefrom and hot and cold water pipes easily separated therefrom, so as to allow easy washing and cleaning.
Another object of the present invention is to provide an electric cold and hot water dispenser with a detachable cold water reservoir in which connection pipes of a cold water pipe are constructed to be easily separated from a connector even without disassembling the cold and hot water dispenser such that unsanitary dusty impurities can be eliminated from the connection pipes.

DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to accompanying drawings.
FIG. 2 is a perspective view illustrating an electric cold and hot water dispenser with a detachable cold water reservoir according to one preferred embodiment of the present invention.
Referring to FIG. 2, the inventive electric cold and hot water dispenser with a detachable cold water reservoir includes a detachable cold water reservoir 21 be easily separated and detached from a cooling reservoir 21a having a refrigerant circulation coil 22 welded thereto and having hot and cold water pipes 26 and 24 connected therewith; the cooling reservoir 21a for supporting the cold water reservoir 21; the refrigerant circulation coil 22 encompassing the cooling reservoir 21a, for cooling water supplied; a hot water reservoir connection pipe 23 connected to a lower part of the cold water reservoir 21 and the cooling reservoir 21a so as to supply a hot water reservoir 25 with hot water; a cold water pipe 24 connected to the lower part of the cold water reservoir 21 and the cooling reservoir 21a so as to supply water cooled by the refrigerant circulation coil 22; and the hot water reservoir 25 for storing the hot water therein prior to providing the hot water for the hot water pipe 26.
Herein, the hot water pipe 26 represents all pipes connected until the hot water is provided from the hot water reservoir connection pipe 23 and the hot water reservoir 25, and the cold water pipe 24 represents all pipes connected until the cold water is provided.
In particular, the inventive electric cold and hot water dispenser, unlike the conventional electric cold and hot water dispenser, is constructed to have the cold water reservoir 21 detachably connected within the cooling reservoir 21a encompassed by the refrigerant circulation coil 22.
For example, the cold water reservoir 21 can be mainly separated into upper and lower parts. The upper and lower parts have all concentric configurations, but a radius of the upper part is larger than that of the lower part. And, the radius of the lower part of the cold water reservoir 21 is almost the same as that of the cooling reservoir 21a for supporting the cold water reservoir 21.
Further, in a fitting part of the cold water reservoir 21 with the cooling reservoir 21a, that is, in a coupling part between the upper and lower parts of the cold water reservoir 21, a groove is formed, and the lower part of the cold water reservoir 21 having a rounded surface connected with the groove is fittingly connected with the cooling reservoir 21a.
Therefore, the cold water reservoir 21 can be fitted and assembled into the cooling reservoir 21a until the upper end of the cooling reservoir 21a is in contact with the groove part of the cold water reservoir 21, and when disassembled, an external force can be applied to the groove part so as to lift up and detach the cold water reservoir 21.
Accordingly, since the cold water reservoir 21 and the cooling reservoir 21a can be separated from each other, in case bacterium or unsanitary dusty impurities are held in the cold water reservoir 21 of a water purifying apparatus and the electric cold and hot water dispenser, whenever necessary, the cold water reservoir 21 can be pulled out for cleaning or washing.
Herein, the cold water reservoir 21 and the cooling reservoir 21a for supporting the cold water reservoir 21 can be formed of different materials.
For example, the cold water reservoir 21 is formed of plastic, and the cooling reservoir 21a supporting the plastic cold water reservoir 21 can be formed of metal or alloy such as stainless steel.
Further, the cold water reservoir 21 and the cooling reservoir 21a supporting the cold water reservoir 21 can be both all formed of the same material such as stainless steel.
Hereinafter, it can be appreciated in detail how the inventive electric cold and hot water dispenser can be separated.
FIG. 3 is a disassembled perspective view illustrating an electric cold and hot water dispenser with a detachable cold water reservoir according to one preferred embodiment of the present invention.
As shown in FIG. 3, the inventive electric cold and hot water dispenser includes the cold water pipe 24 for supplying the cold water cooled by the refrigerant circulation coil; a male screw 26a for connecting the cold water pipe 24 with the cold water reservoir 21 and the cooling reservoir 21a; a female screw 26b connected with the male screw 26a so as to connect the cold water reservoir 21 with the cold water pipe 24; and fitting members 25a, 25c installed between the female screw 26b and the male screw 26a so as to seal a water-leakage space of the cold water reservoir 21.
Further, the hot water reservoir connection pipe 23 and the hot water reservoir 25 connected therewith for storing the hot water can be easily separated from each other in a screwed connection way using connection screws 27a, 27b and fitting members 25b, 25d for sealing the water-leakage space of the cold water reservoir 21.
Furthermore, in the cold water pipe 24 and the cold water reservoir 21, there is provided a locking/unlocking cover 29 such that they can be easily locked or unlocked in the screwed connection way using the male screw 26a and the female screw 26b.
Furthermore, the refrigerant circulation coil 22 encompassing the cooling reservoir 21a can be separated from each other.
In the above-constructed electric cold and hot water dispenser according to the present invention, since the cold water reservoir can be easily separated from the hot and cold water pipes, whenever necessary, it can be easily washed.
Accordingly, water can be maintained to be in a clean and sanitary state with direct relation to our health.
FIGs. 4A to 4C are upper elevation views illustrating the electric cold and hot water dispenser with the detachable cold water reservoir according to one preferred embodiment of the present invention.
FIG. 4A illustrates the upper elevation view of the electric cold and hot water dispenser according to the present invention.
Referring to FIG. 4A, the cold water reservoir 21 and the cooling reservoir 21a are connected with the cold water pipe 24 in the screwed connection way using the fitting member, and also are connected with the hot water pipe 26 through the hot water reservoir connection pipe 23 in the screwed connection way of using the fitting member. It is illustrated that the electric cold and hot water dispenser is constructed in such a precise configuration that water leakage is prevented as in the conventional integral type of the electric cold and hot water dispenser.
FIG. 4B illustrates only the detachable cold water reservoir 21. In FIG. 4B, in a state before the hot and cold water pipes are connected with the cooling reservoir, there are illustrated hole-typed connection parts.
FIG. 4C individually illustrates only the cooling reservoir 21a for supporting the cold water reservoir 21. In FIG. 4C, the cooling reservoir 21a has a hole-typed connection part for the cold water pipe 24 through which the female screw 26b of the cold water pipe can be just pulled out, and has a hole-typed connection part for the hot water reservoir connection pipe 23 through which a hot water reservoir connection screw can be inserted.
FIG. 5 is a disassembled perspective view illustrating an electric cold and hot water dispenser with a detachable cold water reservoir according to another preferred embodiment of the present invention.
As shown in FIG. 5, the electric cold and hot water dispenser according to another embodiment of the present invention is, as in the embodiment of FIGs. 2 to 4, constructed such that the cold water reservoir 21 can be detachably separated from the cooling reservoir 21a, the cold water pipe 24 and the hot water reservoir connection pipe 23.
However, the electric cold and hot water dispenser of FIG. 5 is differentiated from the electric cold and hot water dispenser of FIG. 4 in its construction in that connection pipes of the cold water pipe 24 can be separated using a connector 28 such that the unsanitary dusty impurities (bacterium and rusts) can be eliminated from the connection pipes.
The connector 28 can be constructed in the screwed connection way or in a bolt-nut connection way such that the connection pipes of the cold water pipe 24 can be separated therefrom.
Accordingly, whenever necessary, the washing or cleaning can be made thereby improving a clean state in the water purifying apparatus or/and the electric cold and hot water dispenser.
As described above, the inventive electric cold and hot water dispenser is constructed such that the cold water reservoir can be easily separated so as to, upon necessary, easily perform the washing thereon.
