Abstract

PURPOSE:To obtain safe, cool tasty water by adding a mineral eluting material into a cooling tank. CONSTITUTION:When drinking water flows into a cooling tank 2, an electronic cooling element 5 connected with the cooling tank 2 is actuated to cool drinking water. At the same time, a mineral eluting material 4 such as coral sand and lime stone is added. Minerals such as calcium and magnesium are eluted from the mineral eluting material 4. Cooled drinking water enriched with minerals flows into a water purifying apparatus, where odorous components, trihalogenomethane, residual chlorine, bacteria, colloidal components, and others are removed by hollow fibers 14 and activated carbon 13. In this way, safe, cool tasty water can be obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier with a cooling function for purifying drinking water after cooling it with a water purifier.

[0002]

2. Description of the Related Art Stains and mold odors in tap water supplied to homes tend to increase due to contamination of river water. From the viewpoint of health and safety, problems such as microbial contamination of elevated tanks in buildings and condominiums and generation of red water, as well as asbestos, trihalomethane, and other carcinogens in drinking water have been pointed out. It is getting higher.
For this reason, water purifiers and mineral water have become widespread.

[0003] Also, as can be seen from the report of the Tasty Water Study Group of the Ministry of Health and Welfare, the water temperature at which it feels delicious is said to be 20 ° C or less, and so-called chillers for cooling and supplying drinking water are commercially available, and chilled water is also available. An apparatus that combines cold water and a water purifier to supply cold, safe, and delicious drinking water has also been proposed (JP-A-4-61982, JP-A-4-41982).
-320777 each gazette etc.).

In order to further enhance minerals such as calcium and magnesium, a water purifier in which coral sand, limestone or the like is filled in a cartridge and installed in a flow path has been proposed (Japanese Utility Model Publication No. 60-144992). etc).

[0005]

However, the combination of the above-mentioned chiller and a water purifier in which a cartridge is filled with a mineral-eluting substance such as coral sand or limestone can provide cold and safe mineral-rich delicious water. When used as water for tea, coffee, black tea, etc., since the water temperature is low, it is necessary to heat the water, which consumes a large amount of heating energy and is a wasteful method.

It has been reported that the water used for tea, coffee, and black tea is preferably water with a low mineral content.

[0007]

A water purifier according to a first aspect of the present invention is a water purifier with a cooling function for purifying drinking water after cooling the stored water, wherein a mineral elution substance is added to the cold storage tank. And

The water purifier according to claim 2 is characterized in that the water inlet of the water purifier is provided with means for switching between drinking water and cooling water inside the cold storage tank.

The water purifier according to claim 3 is characterized by comprising a hollow fiber membrane and activated carbon.

The water purifier according to claim 4 is characterized in that the mineral substance is a mineral-eluting substance such as coral sand or limestone.

The present invention will be specifically described below. When the drinking water flows into the cold storage tank, the electronic cooling element connected to the cold storage tank operates to cool the drinking water. At the same time, mineral substances are added to the cold storage tank.

The cooled mineral-rich drinking water flows into the water purifier, and the hollow fiber membrane filter and the activated carbon in the water purifier remove odorous components, trihalomethanes, residual chlorine, bacteria, colloid components, etc., and keep them safe and cool. It becomes delicious water.

It is also possible to select drinking water and cooling water by the switching means provided at the water inlet of the water purifier and purify the water by the water purifier.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is an explanatory view showing an example of a water purifier with a cooling function of the present invention. Reference numeral 1 is an opening / closing valve by which drinking water flows into and is cut off from the main body. The inflowing drinking water flows into the cold storage tank 2 from the cold storage tank inlet port 3 by the switching cock 9 or directly into the water purifier 12 through the drinking water internal pipe 10.

The drinking water that has flowed into the cold storage tank 2 is cooled by the electronic cooling element 5 and is discharged from the mineral-eluting substance 4.
Minerals such as calcium and magnesium are eluted and become mineral-rich drinking water.

A heat radiation fin 6 and a heat radiation fan 7 are connected to the electronic cooling element 5.

The water purifier is composed of activated carbon 13 and hollow fiber membrane 14, and has odor components, trihalomethane, residual chlorine, bacteria,
Colloidal substances are removed. From the above, when cold water is used, by switching the switching cock 9 to the cold water side, delicious water that has been cooled and becomes rich in minerals is obtained, and when the switching cock 9 is switched to the normal temperature side, delicious water at room temperature is obtained. .

According to this embodiment, when the switching cock 9 is switched to the cold water side, the cooled mineral-rich water from the cold storage tank flows into the water purifier 12, and the activated carbon 13 of the water purifier 12 is discharged.
With the hollow fiber membrane 14, the odor component, trihalomethane,
Residual chlorine, bacteria, colloidal components are removed, and safe and cooled delicious water is discharged from the spout 15.
This is suitable for drinking as it is.

When the switching cock 9 is switched to the room temperature side,
Drinking water directly flows into the water purifier 12, and the activated carbon 13 and the hollow fiber membrane 14 of the water purifier 12 remove odorous components, trihalomethanes, residual chlorine, bacteria, and colloidal components, and safe and delicious water flows out from the spout 15. To be done. It is suitable for heating and drinking tea, coffee, tea water, or cooking water.

[0021]

According to the present invention, the drinking water cooled by the electronic cooling element and made mineral-rich by the minerals eluted from the mineral-eluting substance flows into the water purifier, and the hollow fiber membrane filter and the activated carbon in the water purifier. Odor components, trihalomethanes, residual chlorine, bacteria, colloid components, etc. are removed, and safe, cold and delicious water can be obtained.

Further, when cold water such as tea, coffee or black tea or water rich in mineral is not required, safe and delicious room temperature water which does not pass through the cold storage tank can be obtained.
