Abstract

PURPOSE: To prevent steam and hot water discharged from a water purifying tank from being contact with a human body, etc., during the regeneration of an adsorbent by heating. CONSTITUTION: A water purifier regenerates the adsorbent housed therein by heating the water purifying tank 4. An intermediate tank 10 and a solenoid valve 11 are provided in the midway of a hot water discharge pipe 9 for discharging the steam and hot water generated during the regeneration of the adsorbent from the water purifying tank. After the steam and hot water are once stored in this intermediate tank 10 and they are cooled, the solenoid valve 11 is opened and water is discharged. Thus, high temp. steam and water are not discharged directly and danger causing a scald by coming into contact with them is prevented.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier which is connected to a faucet of a water pipe to remove harmful substances in drinking water, and more particularly, to safeguard hot water generated when an adsorbent is boiled and regenerated. It relates to a device for discharging.

2. Description of the Related Art FIG. 2 is a piping system diagram showing a conventional structure of a water purifier of this type. In the figure, the drinking water supplied to the water purification tank 4 from the water supply piping 3 connected to the faucet 1 of the water supply piping via the switching cock 2 is the adsorbent (not shown) made of activated carbon or the like contained in the water purification tank 4. After passing through, harmful substances (moldy odor, trihalomethane, residual chlorine content, etc.) are removed, and are supplied from the purified water pipe 6 to the sink 7 via the switching valve 5. On the other hand, when the adsorbent exceeds a certain water flow rate, the activity decreases due to the accumulation of harmful substances, but the adsorbent can be regenerated by releasing the harmful substances by boiling. Therefore, a heater 8 is arranged at the bottom of the water purification tank 4 and, for example, once a day, the heater 8 is kept in a water-stopped state with the faucet 1 closed.
To heat the water purification tank 4. As a result, the water accumulated inside the purified water tank 4 is boiled, and the adsorbent is boiled and regenerated.

Here, the switching valve 5 is composed of a thermo valve that senses the temperature and switches the flow path, and when the water temperature in the water purification tank 4 rises to a certain temperature, the valve element moves due to deformation of the built-in heat-sensitive part. Then, the outlet of the water purification tank 4 which is normally connected to the water purification pipe 6 is switched to the hot water discharge pipe 9. Therefore, when the water in the water purification tank 4 is heated by energizing the heater 8, steam or hot water generated by boiling of the water is guided to the hot water discharge pipe 9 through the switching valve 5 and discharged to the sink 7. To be done.

[0004]

In the water purifier described above, the inside of the water purification tank 4 is in a boiling state while the adsorbent is being regenerated, and steam or hot water is continuously discharged from the hot water discharge pipe 9. However, since the steam and hot water are extremely hot, it is extremely dangerous to touch the human body, and there is a problem that kitchen utensils and the like in the sink 7 are struck and damaged. Therefore, an object of the present invention is to provide a hot water discharge device of a water purifier in which steam or hot water discharged during regeneration of the adsorbent is prevented from directly contacting a human body or the like.

[0005]

In order to achieve the above-mentioned object, the present invention has a water purification tank equipped with a heater containing an adsorbent having a heat reproducibility, which is harmful to drinking water supplied to the water purification tank. While removing the substance with the adsorbent, in the water purifier in which the heater is energized to regenerate the adsorbent when the activity of the adsorbent is reduced, steam generated in the water purification tank during regeneration of the adsorbent, An intermediate tank for temporarily storing and cooling the steam or hot water and a valve for discharging the water in the intermediate tank are provided in the middle of the hot water discharge pipe for discharging the hot water.

[0006]

According to the present invention, steam or hot water can be temporarily stored in the intermediate tank and cooled, and then the valve can be opened to discharge the water in the intermediate tank. Never touch it directly.

1 is a piping system diagram showing an embodiment of the present invention. The same reference numerals are used for the parts corresponding to the conventional example, and the description of the same components will be omitted. In the illustrated embodiment, a cylindrical intermediate tank 10 is provided in the middle of the hot water discharge pipe 9.
Is inserted, and the solenoid valve 11 is provided downstream thereof, which is a difference from the conventional example. In such a configuration, the solenoid valve 11 is activated during regeneration of the adsorbent by energizing the heater 8.
Is closed, and the steam and hot water introduced from the clean water tank 4 to the hot water discharge pipe 9 through the switching valve 5 are once stored in the intermediate tank and cooled there. When the water in the intermediate tank 10 has cooled after, for example, about 2 hours have passed since the heater 8 was de-energized, the electromagnetic valve 11 is opened and drained by timer control. A manually operated valve such as a cock may be used as a valve in the middle of the hot water discharge pipe 9.

[0008]

According to the present invention, the steam and hot water generated during the regeneration of the adsorbent are temporarily stored in the intermediate tank so that they can be cooled and then drained. The risk of damage to the can be reliably prevented.
