もあった。However, there is a limit to the adsorption capacity of the adsorbent, and if it exceeds the limit, harmful substances and the like pass through without being adsorbed.
Further, there are differences in the adsorption capacity and adsorption rate of various substances to be removed contained in tap water with respect to the adsorbent. For this reason,
With the use of water purifiers, the problem arises that some substances have been removed, but others cannot be removed due to their reduced capacity. Particularly, carcinogenic trihalomethane has a small adsorption capacity for activated carbon and has a low adsorption rate, so that the above-mentioned drawbacks are easily exposed. In addition, since residual chlorine contained in tap water becomes chlorine ions in the activated carbon portion, the bactericidal effect is lost, and there is a problem that bacteria propagate in this portion and become unsanitary.

It is known that when a certain amount of heat energy is applied to this adsorbate, it is desorbed from the adsorbent. Although various methods can be considered as the method of applying thermal energy in this case, it was experimentally confirmed that heating by steam is most effective. The results are shown in Table 1. According to this, it is not completely regenerated by heating with hot water. Also, hot air regeneration with hot air requires treatment at high temperature for a considerably long time. On the other hand, with steam, almost 100% regeneration effect is shown in a short time.

Since the water that flows into the inside has a small amount of colloidal substances and particulate substances, the surface of the adsorbent 24 is not covered with these substances so that the adsorption capacity is not deteriorated. Further, even when the purified water is not supplied, water is accumulated inside the filtering device 3 and the steam generating portion 2, but this water is absorbed by the adsorbent 2 such as activated carbon.
Since 4 does not pass through the water purifying unit 1 in which the accommodating and arranging is performed, chlorine for disinfection in tap water is not removed, and no germs propagate therein.

力が低下するようなことがない。At the time of regeneration, the water supply on-off valve 17 is closed as means for sending the steam generated in the steam generating section 2 to the water purifying section 1.
The hot water switching valve 13 is connected to the clean water outlet 20 and the steam outlet 8.
And the water in the steam generating part 2 is heated by the heating device 6. As a result, the internal pressure rises with the generation of steam, the water in the water purification unit 1 is pushed out, and is discharged to the hot water switching valve 13 and the steam discharge port 8. When the water is pushed out, the adsorbent 24 in the water purification section 1 is heated by the steam that continues to flow, and the adsorbent 24 is regenerated by this thermal energy. The steam that has passed through the water purification unit 1 is discharged to the hot water switching valve 13 and the steam discharge port 8. Here, since the water that has passed through the filtering device 3 passes through the water purification unit 1, there are few substances that hinder the regeneration on the surface of the adsorbent 24, and the regeneration efficiency is high. In addition, in order to make the steam flow during regeneration from the upper side to the lower side, the water purification unit 1
Condensed water of vapor rarely accumulates inside, and trihalomethane is less likely to be generated in the accumulated water. Therefore, despite the regeneration operation, there is no possibility that the ability to remove trihalomethane will deteriorate due to returning.

It may be made of a shape memory alloy or the like. Further, although the heating device 6 is used as the means for aerating the steam in the above embodiment, the ventilation means is not limited to this, and the air may be supplied by means such as another blower.

This is used as a water purifier, remove only the water purifier 1 whose adsorption capacity has decreased from the water purifier body (not shown),
It is configured such that it can be connected to a steam generating unit 2 as a device different from the water purifier main body via a connecting unit 7. In this case, as the connecting portion 7, there is a rubber tube or the like as a simple one, but a screw or the like may be used. With this configuration, the water purifier body can be made compact, and by performing regeneration only when necessary, even when there are a plurality of water purifier bodies, only one regenerator is required, which is economical.

２２はともに蒸気発生部２の上部に設けられる。FIG. 4 shows still another embodiment in which the steam shutoff valve 12 as the outflow prevention means is replaced with a water shutoff method. This is provided with a water sealing portion 15 formed of a U-shaped pipe 15a between the steam generating portion outlet 22 and the purified water supply port 4. As for the positional relationship of the pipes in this case, the water purification part inlet 19 is the lower part of the water purification part 1, the water purification part outlet 20 is the upper part of the water purification part 1, and both the steam generation part inlet 21 and the steam generation part outlet 22 generate steam.

るようになっている。In the operating state, the steam generated in the steam generating section 2 is condensed and gradually accumulated in the water sealing section 15 consisting of the U-shaped pipe 15a, and the level of the water in the water purifying section 1 increases. When the difference H becomes equal, it is water-sealed at that time, and all the generated steam flows through the steam generating unit inlet 21 into the water purifying unit 1 from the water purifying unit outlet 20 and flows out from the water purifying unit inlet 19. It is discharged to the outside of the system through the regeneration switching valve 16 and the steam discharge port 8. With this structure, even if the internal pressure becomes high due to abnormal excessive temperature rise due to a failure of the heating device 6 or switching to the steam discharge port 8 side due to a failure of the switching valve 16 during regeneration. By pushing out the water in the V-shaped pipe 15a, the internal pressure can be released to the outside, and the worst situation of explosion due to excessive temperature rise can be prevented.

This is directly discharged from the steam discharge port 8, and this method is the simplest in the apparatus. In addition, FIG. 5B shows a case where all of the discharged amount is condensed and discharged. This is to attach a heat exchanger 23 to the tip of the steam outlet 8 so that the desorption substance due to regeneration, for example, the condensation temperature of trihalomethane is lower than 61.2 ° C. As a result, trihalomethane etc. also condense in water,
There is no danger that it will be volatilized again into the air and inhaled by the people around it, adversely affecting health.

的で安全な水が供給できることとなる。This eliminates the need for heat insulation of the water purifying section 1 so that the apparatus itself becomes compact and the water purifying section 1 is regenerated at the time of regeneration.
Since there is high-temperature water on the outside of the container, the temperature of the container of the water purification unit 1 also becomes high, and almost all of the heat quantity of the steam is given to the adsorbent 24 without condensation of the steam in the container, resulting in high regeneration efficiency. The control means of the present invention is shown in FIG.
Regardless of the amount of purified water used, the heating device 6 heats for a constant time L 1 and a constant temperature T 1 each time a constant time L 0 elapses. Further, in parallel with this, when the cumulative amount of purified water used reaches a certain amount M, heating is performed for a certain time L 2 to a constant temperature T 2 . If L 1 is the time for the propagation of various bacteria in the device and T 1 is the temperature at which the bacteria can be sterilized, this heating can always keep the device free of the bacteria. Further, if a fixed amount M is set as a limit usage amount of trihalomethane or the like flowing out from the adsorbent 24, and a fixed time T 2 and a constant temperature L 2 are temperatures and times required for desorbing the substance from the adsorbent 24. Due to this heating, the purified water from the water purification unit 1 does not contain harmful substances such as trihalomethane, so that sanitary and safe water can always be supplied.
