臭を除去していた。2. Description of the Related Art Since tap water in recent years has been sterilized with chlorine, it contains a large amount of free chlorine and has a lot of chlorine odor. Therefore, in the conventional hot water supply apparatus, free chlorine and trihalomethane in the water were released into the atmosphere by maintaining the boiling for several minutes, and the odor of the tap water in the tap water was removed.

m and the deviation (σ) are 0.12. x + 3σ = 0.99
Therefore, it can be said that 1.0 ppm of free chlorine has a sufficiently high concentration.

生が少ない。そこで以下の試験を行った。However, when activated carbon is used in the water heater, it is conceivable that fragments of activated carbon or fine powder of activated carbon will be mixed in the hot water. Since hot water is often used for drinking in a hot water supply device, if a product lacking activated carbon or fine powder is mixed with hot water, it will be unattractive and you cannot enjoy tea or the like. Activated carbon may rub against each other when the water heater is transported or carried. As shown in FIG. 2 (a) , the sharpened activated carbon 21 rubs during transportation and the like, and the activated carbon is easily chipped off to generate broken carbon 22, but as shown in FIG. 2 (b).
As described above, the spherical activated carbon 23 is not easily chipped. In addition, since activated carbon made from synthetic resin raw material is made from pure raw material,
The structure of activated carbon is easily crystallized and becomes dense. for that reason,
It is harder than activated carbon made from raw materials containing impurities, and produces less fine powder due to friction between activated carbon during transportation. Therefore, the following test was conducted.

And crushed charcoal 29 made from coconut shells. As shown in FIG. 1, 150 g of each activated carbon was attached to a hot water supply device, and the hot water supply device was attached to a shaker that reciprocated twice with an amplitude of 10 cm per second and shaken for 10 hours. For measurement of cracks and fine powder of activated carbon, use ultrapure water as the solution,
Otherwise, after boiling water in the same manner as in Condition 2 of Experimental Example 1,
2000 ml was sampled. The sampled hot water was filtered through a membrane filter having 0.4 μm pores, and the powder drop from the activated carbon was determined by the weight change before and after the filtration. The results are shown in (Table 2).

そこで以下の試験を行った。However, when activated carbon is used in the water heater, it is conceivable that activated carbon fragments or activated carbon fine powder may be mixed into the hot water. Since hot water is often used for drinking in a hot water supply device, if a product lacking activated carbon or fine powder is mixed with hot water, it will be unattractive and you cannot enjoy tea or the like. Activated carbon may rub against each other when the water heater is transported or carried. As shown in FIG. 2, activated carbon has a pointed end is rubbing during transportation, but lacks easily the end of the activated carbon
Sphere-like activated carbon is difficult missing. In addition, since activated carbon made from synthetic resin raw materials is made from pure raw materials, the structure of activated carbon is easily crystallized and becomes dense. Therefore, it is harder than the activated carbon made from the raw material containing impurities, and the generation of fine powder is less likely due to the friction between the activated carbons during transportation.
Therefore, the following test was conducted.

It was attached to a shaker that reciprocates twice per second in cm, and was shaken for 10 hours. Then, for the measurement of cracks and fine powder of activated carbon, ultrapure water was used as the solution, and the boiling water was boiled by the same method as in Condition 2 of Experimental Example 1, and then 2000 ml was sampled. The sampled hot water was filtered through a membrane filter having 0.4 μm pores, and the powder drop from the activated carbon was determined by the weight change before and after the filtration. The results are shown in (Table 4).

Therefore, as the activated carbon used in the hot water supply apparatus as in this embodiment, spherical activated carbon made of synthetic resin is effective.

Is discharged to the discharge pipe 60. At this time, if the switch 69 is operated to open the switching valve 61 in the passage on the side of the water inlet 62, hot water is supplied from the water inlet 62 to the outside. At this time, if the valve is opened on the circulation path side, hot water is poured into the activated carbon layer 72 through the circulation port 63. Most of the hot water poured into the activated carbon layer 72 circulates through the activated carbon layer 72 into the container 52.

The main body 51 of the water heater is energized, the push button 66 is pushed down, and the pump 57
Is operated to supply hot water through the circulation port 63 at a flow rate of 1200 ml / m.
Let's circulate in. At this time, the free chlorine concentration in the hot water changed as shown in FIG. In this experiment, the free chlorine concentration was quantified according to the residual chlorine item of the water purification test method, the DPD method. The vertical axis is the free chlorine concentration, and the horizontal axis is the heating time. FIG. 6A shows a change in the concentration of free chlorine caused only by ordinary heating, and FIG.
For about a minute, c is about 5.5 when the hot water temperature is from 73.5 ° C to 95 ° C.
And d indicates the change in free chlorine concentration when circulated from 83.5 ° C. to 95 ° C. for about 3.5 minutes. As is clear from FIG. 6, the inclination is larger as the circulation from the high temperature is higher, and the removal performance of free chlorine is higher. That is, it can be said that the higher the temperature is, the shorter the time is effective. Then, water having a free chlorine concentration of 1.0 ppm could be reduced to 0.1 ppm or less by circulation for about 8 minutes.
