Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a water purifier with a chiller.

[0002]

2. Description of the Related Art A known example closest to the present invention is disclosed in JP-A-4-3.
There is a 20777 publication.

In the conventional water purifier with a chiller, although there is a switching means for directly purifying water from the water purifier and a cooling water for purifying water from the water purifier through the cooler, the direct intake of the cooling water is possible. Therefore, when the cooling water is not used for a long period of time, bacteria are generated in the cooling water, and when it is drunk as it is, it causes diarrhea and the like.

[0004]

In the above structure, the cooling water must be used frequently or kept at a low temperature that can prevent the generation of bacteria.

In the present invention, the water purification element of the water purifier uses activated carbon to remove residual chlorine and harmful organic substances, but a hollow fiber membrane is attached to the inside of the cooler to remove turbidity and bacteria. Even in the case of purified water, the water is taken in through the hollow fiber membrane in the cooler at the final stage by the action of the special switching valve that distinguishes between the two.

[0006]

[Means for solving the problem] In the case of pure water only, water is taken through activated carbon as a water purification element in the water purifier and the hollow fiber membrane in the water cooler, and in the case of cooling water, tap water is purified by the action of the switching valve. After passing through the activated carbon of the vessel, it enters the cooling tank, and the cooling water pressed by the tap water pressure and cooled in advance by the Peltier element is taken in through the hollow fiber membrane in the water cooler.

In the present invention, the purification of tap water is installed by dividing it into both the activated carbon in the water purifier and the hollow fiber membrane in the water cooler, both of which are used when the purified water is used by the action of a special switching valve. Water purifier → route to hollow fiber membrane in cooling tank, and when using cold water, route to water purifier → cooler → hollow fiber membrane, in each case having the function of removing turbidity and bacteria at the final stage The main feature is to arrange a hollow fiber membrane.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment in which cooling water is used. Tap water flows from the faucet 1 into the water purifier 2 through the water purifier inlet 4 by the hose 3, and the activated carbon 5 removes residual chlorine and harmful organic substances. To be removed. The purified water thereafter flows into the cooler 7 from the passage 6 through the switching valve 19, is cooled in the cooling chamber 9 by the Peltier element 8, and is gradually cooled while being circulated by the circulation pump 10. The heat radiating side of the Peltier element is air-cooled by a heat radiating fin 31 by a fan 11 driven by a motor 30 shared with the circulation pump 10. The purified water flows into the water cooler 7 through the passage 12 through the switching valve 19, is guided to the upper portion of the water cooler 7 through the passage 13 in the water cooler 7, and is cooled in advance by the tap water pressure. From the cold water at the bottom of the water cooler, through the communication hole 14 at the bottom of the water cooler, through the hollow fiber membrane 15 built in at the top of the water cooler 7, the turbidity and bacteria in the water are physically filtered, and Water is taken.

Inside the water cooler 7, a hollow portion 17 is provided near the upper center.
The hollow fiber membrane 15 surrounded by is attached. On the upstream side of the water cooler 7, a switching valve 1 rotated by a lever 18
A communication hole 22 is provided at the opening 20 when the water is purified and at the opening 21 when the cold water is rotated by 180 degrees so as to communicate with the respective openings.

FIG. 2 shows the position of the switching valve 19 in the case of pure water only, and the water purified by the activated carbon 5 is the lever 18
By the rotation of, the opening 20 and the communication port 22 are communicated with each other, and water is taken from the purified water / cold water faucet 16 through the passage 23, the communication pipe 24 in the water cooler 7, and the hollow fiber membrane 15.

As can be seen from these examples, the intake of the common hollow fiber membrane 15 is the same for both pure water and cooling water.
It is designed to be taken in through water, and the pores made of polysulfone etc. with a diameter of 0.1 or less physically remove not only turbidity but also Escherichia coli and general bacteria. It is possible to get clean drinking water.

[0013]

EFFECTS OF THE INVENTION According to the present invention, clean water intake that is not contaminated by bacteria or the like that has passed through the same hollow fiber membrane in the same water cooler in both cases of purifying water and cooling water intake The cooling water can be obtained without impairing the original function of the water purifier.
