Description

Tank type hot and cold water purifier

The present invention relates to a tank cold water purifier. More specifically, the present invention is a tank-type cold and hot water purifier that discharges the raw water stored in the raw water tank through the filter to separate the room temperature / cold / hot water purification, and further improved in hygienic aspects as well as convenience in installation and use and maintenance. It relates to a tank type cold and hot water purifier.

Generally, a water purifier is a device for purifying raw water, such as tap water, with drinking water suitable for the provisions of Article 5 (3) of the Drinking Water Management Act. Osmotic pressure, ion exchange resin, depending on the raw water supply method can be divided into water direct type and storage type.

First, a filter filtration formula obtains purified water by passing raw water through a filter, and a distillation formula obtains purified water by collecting steam according to the heating of raw water. ion-exchanged water knowledge by using the ion exchange resin is a special polymerization sum material was substituted for harmful ion, such as within the Mg ^{2 +,} Ca ^{2 +} in the raw water and harmless ions such as Na ⁺ to obtain an integer.

In addition, the water direct type directly connects the water purifier to the water supply pipe where raw water is supplied, and passes the filter at the supply pressure of the raw water to obtain purified water, and the storage type stores the raw water of a certain capacity in a separate raw water tank to the gravity or pump. The water is passed through the filter at a supply pressure of. Therefore, a separate raw water tank is not required for a direct water purifier, but a raw water tank for supplying and storing raw water is essential for a storage type water purifier, and thus a storage type water purifier is often called a tank type water purifier.

On the other hand, the tank unit 100 of the cold / hot water purifier according to the present invention in the above description is a hot water tank (T3) in addition to the connection structure for transferring the purified water of the purified water tank to the cold water tank (T2) and warm water tank (T3) ) And another connection structure for connecting the cold water tank (T2) to provide a warm water delivery port (136). In this case, preferably, at least one check valve 138 may be mounted at the warm water delivery port 136 to allow only the flow of warm water flowing from the warm water tank T3 to the cold water tank T2, although the drawing Although not shown, a separate auxiliary pump for supplying the warm water of the warm water tank (T3) to the cold water tank (T2) may be used.

The reason for connecting the hot water tank (T3) and the cold water tank (T2) through the check valve 138 and the auxiliary pump as described above is the cold water tank (T2) and the water purification tank (T1) using the warm water In order to sterilize the user, the user operates the auxiliary pump at an appropriate time and delivers the purified water of the purified water tank (T3) to the cold purified water tank (T2) and purified water tank (T1) to cool the purified water tank (T2) and purified water tank. (T1) It is possible to autoclave the inside.

At this time, the cold water tank (T2) is integrally provided on one side lower end of the purified water tank (T1) is divided into a circulation plate 122 capable of water circulation is a high temperature sterilization action of the purified water tank (T1) using convection. It is to facilitate. In other words, the room temperature purified water having a low specific gravity is stored in the purified water tank T1 during normal use of the cold purified water purifier according to the present invention, and the cold purified water tank T2 has a relatively high specific gravity cold stored water, so there is little room for mixing. On the other hand, when the warm water of the warm water tank (T3) flows into the cold water tank (T2), the warm water with the lowest specific gravity rises to sterilize the whole of the clean water tank (T1) including the cold water tank (T2).

Therefore, the cold water purifier according to the present invention can more effectively sterilize the purified water tank T1 and the cold purified water tank T2.
