Description

[0001] Water purifier with circulating sterilizing system [0002]

The present invention relates to a water purifier provided with a circulating sterilization system for sequentially sterilizing a circulation duct, a water intake duct, and a water storage tank with a temperature rising while water discharged from a water storage tank passes through a heating device.

Recently, the use of water purifiers that provide cold or hot water in homes or offices is increasing. Such a common water purifier is periodically inspected to confirm whether it is suitable for drinking for a certain period of time. Particularly, as users' interest in the safety of drinking water supplied from a water purifier has increased, it has become an important task to provide a water purifier incorporating a sterilizing function in the market.

The raw water stored in the water storage unit installed in the water purifier is already subjected to filtration through the plurality of filter units. However, if a very small amount of foreign matter such as bacteria remains in the filtered water, Water inside the compartment may be contaminated.

In order to solve such a problem, a sterilizing water purifier has been developed in which a sterilizing liquid such as chlorine oxide is injected into a water reservoir for automatically sterilizing a water storage portion of a water purifier and a system for draining the sterilized water is added. However, such a sterilizing water purifier requires a separate drain pump separately for draining the water inside the water storage unit, which causes a problem that the manufacturing cost increases greatly. Further, even if the sterilization of the water reservoir is performed, there is a further problem in that an additional sterilization apparatus is required near the discharge cock where the water is discharged to the outside.

Korean Patent Laid-Open Publication No. 10-2010-0136797 discloses an apparatus for sterilizing water to be transferred to the discharge cock, in which a silver-ion filter unit using silver powder is mounted inside the discharge cock, The contents of a cold / hot water heater capable of enhancing the effect are disclosed. However, according to the above-mentioned prior art, since the system for sterilization is not provided in the moving pipe of the raw water disposed inside the cold / hot water heater, the sterilization problem of the raw water can not be fundamentally solved and the manufacturing process of the silver filter is added. There was a problem that the cost became complicated.

Korean Patent Publication No. 10-2010-0136797 (published on December 29, 2010).

The present invention has been developed in order to overcome the limitations and problems of the prior art as described above. Specifically, the water stored in the water storage tank rises along the circulation duct provided with the heating device, The internal construction of the water purifier and the sterilization of the internal piping.

According to an aspect of the present invention, there is provided a water circulation system comprising: a water storage tank for storing water; an inflow circulation tube through which water stored in the water storage tank flows; a discharge circulation tube extending in a direction parallel to the extending direction of the inflow circulation tube; A circulation duct including a bending circulation pipe connected to one side of the inflow circulation pipe and one side of the discharge circulation pipe and bent to have a predetermined curvature and a circulation duct connected to the water reservoir at one side and to the discharge cock at the other side, Wherein the discharge circulation pipe is provided with a projection disposed in an inner space of the water intake pipe and protruding inward from an outer surface of the water intake pipe, And a guide hole for guiding the water to be moved toward the circulation sterilization system. A counterflow water purifier is provided.

According to the present invention, since the water stored in the water storage tank is heated to a high temperature while passing through a discharge circulation line equipped with a heating device, the inner structure of the water purifier and the internal pipe can be efficiently sterilized by circulation of the hot water .

Further, since the guide hole for guiding the movement of water in the direction of the discharge cock is formed at one side of the discharge circulation duct, sterilization can be smoothly performed to the end of the discharge cock.

In addition, the water heated by the heating device sequentially passes through the circulation duct, the water intake duct, and the water storage tank, and sterilizes the respective constitutions, so that it is possible to supply completely sterilized water to the user.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby.

FIG. 1 is a schematic perspective view showing the internal structure of a part of a water purifier according to the present invention, and FIG. 2 is a schematic sectional view taken along line I-I 'of FIG. Fig. 3 is a schematic enlarged view of an enlarged portion A of Fig. 2, and Fig. 4 is a schematic enlarged view of an enlarged view of a portion B of Fig.

As shown in the figure, the water purifier 1 according to an embodiment of the present invention includes a cold water tank 10 for storing cold water and a hot water tank 15 connected to the cold water tank 10 for storing hot water . The cold water tank 10 and the hot water tank 15 are connected to each other by a moving pipe that provides a water passage so that the water stored in the cold water tank 10 can be moved to the hot water tank 15.

The cold water tank (10) is disposed above the bracket (50) for partitioning the inner space of the water purifier (1). The bracket 50 is fixedly mounted to a housing forming an outer surface of the water purifier 1 through a fastening member such as a screw or a bolt. The water stored in the cold water tank 10 is transferred to the circulation pipe 20 through the inlet hole 11 formed in the lower surface of the cold water tank 10. That is, the inlet hole 11 may be defined as an initial point where water stored in the cold water tank 10 flows into the circulation duct 20. In addition, the water stored in the cold water tank 10 may be introduced into the circulation line 20 in a state in which the amount of water movement is controlled by the adjustment adapter 21a.

As shown in the drawing, the water purifier 1 according to the present invention has been described in which water passing through the cold water tank 10 moves along the circulation duct 20 to perform sterilization. However, For example, it is possible that the water passing through the hot water tank 15 moves along the circulation duct 20 to perform the sterilizing action.

However, in the present specification, the internal structure of the water purifier 1 or the internal pipe is sterilized by water stored in the water tank 10 for convenience of explanation.

The circulation duct 20 includes an inlet circulation pipe 21 and a discharge circulation pipe 23 which are made of a straight piping and a pipe connecting one side of the inflow circulation pipe 21 and one side of the discharge circulation pipe 23, And a bending circulation pipe 22 bent to have a curvature. That is, the entire shape of the circulation duct 20 may be formed in a U-shape. In the drawing, the inflow circulation pipe 21, the bending circulation pipe 22 and the discharge circulation pipe 23 are formed as separate components and assembled to each other. However, the present invention is not limited to this, (20) may be integrally manufactured.

The discharge circulation pipe 23 is provided with a heating device 24 for heating water to be moved in the cold water tank 10. Specifically, the water stored in the cold water tank 10 is transferred to the discharge circulation pipe 23 while passing through the inflow circulation pipe 21 and the bending circulation pipe 22 in order. At this time, the water moved to the discharge circulation pipe 23 is heated by the heating device 24, and the hot water acts as sterilizing water. The heating device 24 is formed to surround the outside of the discharge circulation pipe 23. A heat conduction plate 24a made of a conductive material such as aluminum may be disposed between the heating device 24 and the discharge circulation pipe 23. The heat conduction plate 24a transfers the heat energy generated in the heating device 24 to the water flowing along the discharge circulation pipe 23. Therefore, the natural convection phenomenon occurs in the water moving along the discharge circulation pipe 23 by the heating device 24, and the high temperature water can smoothly move according to the phenomenon.

The width of the discharge circulation pipe (23) is larger than the width of the inflow circulation pipe (21) and the bending circulation pipe (22). In other words, the cross-sectional diameter of the discharge circulation pipe 21 is relatively larger than the cross-sectional diameter of the bending circulation pipe 22. The fact that the plurality of circulation pipes constituting the circulation duct 20 have different widths is related to reducing noise generation.

Specifically, when the cross-sectional diameter of the discharge circulation pipe 23 is reduced, the thermal contact area between the discharge circulation pipe 23 and the heating device 24 surrounding the discharge circulation pipe 23 becomes small. Accordingly, if the cross-sectional diameter of the discharge circulation pipe 23 is reduced, the amount of heat generated per unit area of the discharge circulation pipe 23 by the heating device 24 becomes relatively large. This phenomenon causes a larger noise when the sterilizing mode of the water purifier 1 is operated.

The applicant of the present invention studied the correlation between the cross-sectional diameter of the discharge circulation pipe 23 and the noise through actual experiments, and as a result, the experimental results as shown in the following table were derived.

Sectional diameter of discharge circulation pipe (mm) Section diameter of inflow circulation tube and bending circulation tube (mm) Size of noise (dB) 9.52 9.52 40 12.7 9.52 36

In general, the cross-sectional diameter of the circulation duct 20 is 8 mm to 10 mm, preferably 9.52 mm, in consideration of the speed of water and the frictional force acting on water. At this time, the water passing through the discharge circulation pipe 23 has a noise level of about 40 dB and the temperature rises. However, in the present invention, when the same experiment is performed by changing the sectional diameter of the discharge circulation pipe 23 from 9.52 mm to 11 mm to 14 mm, preferably 12.7 mm, water passing through the discharge circulation pipe 23 The results show that the effect of the same temperature rise occurs with a noise level of about 36dB.

That is, if the cross-sectional diameter of the discharge circulation pipe 23 is relatively larger than that of the inflow circulation pipe 21 and the bending circulation pipe 22, the calorific value per unit area of the discharge circulation pipe 23 becomes small, There is an effect that the magnitude of the noise decreases when the temperature rises. However, if the discharge circulation pipe 23 has a cross-sectional diameter larger than 14 mm, the movement of water from the bending circulation pipe 22 to the discharge circulation pipe 23 is not smooth, 23) is most effective to have a cross-sectional diameter of 11 mm to 14 mm, preferably 12.7 mm.

A guide hole 23a is formed at one side of the discharge circulation pipe 23, which is a path through which water passing through the circulation duct 20 flows to the water intake duct 30. The guide hole 23a may be defined as a hole formed toward the direction of the discharge cock 40, which can be operated by the user. The water discharged from the guide hole 23a moves to the water intake duct 30. Specifically, the discharge circulation pipe 23 is arranged to pass through one surface of the water intake duct 30 such that the guide hole 23a is formed inside the water intake duct 30. That is, one side of the discharge circulation pipe 23 is disposed inside the water intake duct 30, and a protrusion protruding inward from the outer surface of the water intake duct 30 is formed.

The discharge circulation pipe (23) and the water intake duct (30) extend in directions perpendicular to each other. Therefore, the water, which is moved up and down along the discharge circulation pipe 23, is moved in the lateral direction along the water intake duct 30 through the guide hole 23a. A part of the discharge circulation pipe 23 is arranged to be received in the water intake pipe 30 and a part of the discharge circulation pipe 23 accommodated in the water intake pipe 30 is inserted into the guide hole 23a, So as to guide the change of the moving direction of the water.

The center point of the guide hole 23a may be disposed at a position relatively lower than a center point of the width of the water intake duct 30. [ Specifically, the water passing through the discharge circulation pipe 23 and moving to the water intake duct 30 can move along the lower portion of the water intake duct 30. The water discharged from the discharge circulation pipe 23 is moved along the lower portion of the water intake duct 30 when the water is discharged to the discharge cock 40. When the water is returned from the discharge cock 40 to the cold water tank 10 And moves along the upper portion of the water intake duct (30), so that the flow of water can be smoothly performed inside the water intake duct (30).

The width W of the water intake duct 30 is relatively larger than the length L of the discharge circular duct 23 accommodated in the water intake duct 30. Therefore, the discharge cock 40 is passed between the discharge circulation pipe 23 accommodated in the water intake duct 30 and the inner end face of the water intake duct 30 on the basis of the cross-sectional diameter of the water intake duct 30 A hollow is formed as a passage through which a water is moved. Therefore, the water passing through the end of the discharge cock 40 can be smoothly moved to the cold water tank 10 through the hollow.

A plurality of return holes 12 are formed in the lower surface of the cold water tank 10, through which the water that has passed through the water intake duct 30 flows into the cold water tank 10. That is, the lower surface of the cold water tank 10 is provided with an inflow hole 11 which is a passage through which the water stored in the cold water tank 10 is transferred to the inflow circulation pipe 21, (See FIG. 4). The return hole 12 is a passage through which the cold water tank 10 is moved. Although the inlet holes 11 are formed at the center of the lower surface of the cold water tank 10 and the plurality of return holes 12 are formed so as to surround the inlet holes 11, And the position of the return hole 12 are not limited thereto, and various other embodiments are possible.

Hereinafter, a process of sterilizing the internal piping and the internal structure of the water purifier 1 while water stored in the cold water tank 10 passes through a plurality of pipelines will be described in detail.

FIG. 5 is a schematic water flow chart showing how water stored in the cold water tank is moved during the sterilization mode operation. FIG.

The operating mode of the water purifier 1 according to the present invention is such that the water intake mode in which the water stored in the water tank 10 is supplied to the user and the water stored in the water tank 10 sterilize the internal structure of the water purifier 1, And a sterilization mode returning to the bath (10).

First, when the water purifier 1 operates in the sterilization mode, the water stored in the cold water tank 10 flows into the circulation duct 20 through the inlet hole 11. A heating device 24 for applying heat to water is installed in the discharge circulation pipe 23 constituting one part of the circulation duct 20 and the heating device 24 is operated to be in the on state in the sterilization mode. The water heated to a high temperature by the heating device 24 passes through the guide hole 23a and is moved downwardly of the water intake duct 30. The water that has passed through the end of the discharge cock 40 along the downward direction of the water intake duct 30 is returned to move along the water intake duct 30 and the inner end surface of the water intake duct 30 and the discharge circular pipe 23, And then flows into the cold water tank 10 through the hollow formed between the projecting portions of the water tank 10.

When the water purifier 1 operates in the sterilization mode, the water stored in the cold water tank 10 is circulated through the circulation duct 20, the water intake duct 30, the discharge cock 40, the water intake duct 30, The inner structure of the water purifier 1 and the inner pipe can be sterilized while sequentially passing through the cold water tank 10.

Next, when the water purifier 1 is operated in the water intake mode, the heating device 24 is operated to be in the off state, and the water stored in the cold water tank 10 is circulated through the circulation pipe 20, And the discharge cock 40 to be supplied to the user.

The water purifier 1 according to the present invention may further include a controller (not shown) for determining the traveling path of the water stored in the cold water tank 10 by determining information on the operation mode. Also, in the present embodiment, the operation mode of the water purifier 1 is described as being divided into the water intake mode and the sterilization mode, but a plurality of operation modes may be set as necessary. For example, the operation mode of the water purifier 1 may further include a manual mode in which the water intake mode and the sterilization mode are changed according to a user's operation.

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.
