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 hot water supply device having a function of regenerating activated carbon.

[0002]

2. Description of the Related Art In recent years, tap water has been disinfected with hypochlorous acid during the treatment process. Therefore, chlorine odor is strong and trihalomethane harmful to the human body is produced by reacting with humic substances and the like by residual chlorine. In the summer months, algae called blue-green algae are generated in large quantities in lakes and marshes that serve as raw water, and tap water smells moldy. These events are particularly pronounced in populated urban areas, where many households use water purifiers. These conventional water purifiers attempt to remove these defective components by using the adsorption action of activated carbon.

[0003]

However, in the purification method by adsorption of activated carbon, it is very short to effectively remove defective components in tap water. In particular, trihalomethane has a low adsorption rate and is quickly desorbed. Therefore, when used for a certain period or more, the trihalomethane adsorbed on the activated carbon is released and comes out at a concentration higher than that of raw tap water. Therefore, in order to purify water effectively, it is necessary to exchange activated carbon in a very short period of time. Therefore, it is possible to regenerate activated carbon. Activated carbon has a smaller amount of adsorption as the temperature becomes higher. The substance adsorbed at room temperature is raised to a high temperature and desorbed to regenerate. However, the activated carbon regeneration rate varies greatly depending on the regeneration means. The difference in adsorption due to temperature is large when the temperature difference is large, that is, at a high temperature, but energy is required to obtain a high temperature. Therefore, if a new heating device is provided for the regeneration of activated carbon, the entire device becomes large and bulky. In addition, there is a problem that much energy is consumed.

The first object of the present invention is to solve the above-mentioned problems, and a first object of the present invention is to provide a water purifier with a hot water supply device for efficiently regenerating activated carbon and effectively removing defective components over a long period of time. A second object of the present invention is to provide a water purifier with a water heater using means for increasing the efficiency of the object, and to provide a water purifier with a water heater with means for making the first and second objects more effective. A third object is to provide a container.

[0005]

In order to achieve this object, in a water purifier with a water heater according to the present invention, as a first means, a water purifier containing activated carbon and having a pore at a bottom is passed through a steam purifier. A bottom plate having a pipe, a container for storing water, a hot water supply unit having a heater for heating water in the container, and a valve for switching water flow between the water purification unit and the hot water supply unit are provided.

As a second means, in addition to the first structure, a control device for opening and closing the ventilation valve at a certain pressure is provided.

As a third means, in addition to the first and second configurations, a blade for stirring the activated carbon and a motor for driving the blade are provided.

[0008]

According to the first aspect of the present invention, the activated carbon in the water purifying section is regenerated without waste of energy by the steam generated when heating the water, effectively removing the defective components in the tap water for a long time, and safely and safely. Delicious water or hot water is obtained.

According to the second configuration, the heating steam used for the regeneration of the activated carbon, the boiling steam is retained by closing the ventilation valve. And the playback rate is improved.

According to the third configuration, the activated carbon is agitated, the specific surface area is effectively used, and the adsorption is effectively performed. Also, during the regeneration, the heat is quickly transferred to the entire activated carbon that has been effectively desorbed by stirring, thereby improving the efficiency of the regeneration.

Is a heater for heating the water in the water storage container 2, and 7 is a temperature sensor for sensing the temperature of the water in the water storage container 2. 8 is an inlet for tap water, 9 is a fibrous activated carbon for water purification (felt-like thing cut finely), 10 is a hollow fiber membrane for water purification, 1
1 is a pump for sending water purified by the water purification container 3, 12 is a pipe, and 13 is a switching valve for switching between using purified water as hot water and water. 14 is a pipe, 15 is a switching valve for switching between normal temperature and hot water, and 16 is a water outlet. Reference numeral 17 denotes a pipe for sending normal-temperature purified water to the water storage container 2, reference numeral 18 denotes a water intake for taking boiled hot water, reference numeral 19 denotes a pump, and reference numeral 20 denotes a pipe.

The operation of the water purifier with the hot water supply device configured as described above will be described with reference to FIG. First,
Tap water enters the water purification container 3 through the inlet 8. In the water purification container 3, water is purified by the fibrous activated carbon 9 and the hollow fiber membrane 10. The purified water is sent by a pump 11 to a switching valve 13 through a pipe 12. When water is used, it flows from the switching valve 15 to the water outlet 16 through the pipe 14. When water is added to the water storage container 2, the switching valve 13 opens toward the pipe 17. The water in the water storage container 2 is heated by the heater 6, and when it boils, the temperature sensor 7
Is sensed and kept warm. When hot water is used, when a switch not shown in the figure is turned on, the pump 19 is operated and hot water flows from the water intake port 18 through the pipe 20 to the water outlet 16 from the switching valve 15. The switching valve 15 can switch between hot and cold water by a switch not shown. Further, the switching valve 13 at the time of boiling of the hot water is opened to the water use side, and the boiling steam enters from the pores of the water purification container 3 through the pipe in the bottom plate 4. The boiling steam heats the fibrous activated carbon 9, desorbs the adsorbed substances, and performs regeneration.

In this activated carbon regeneration mechanism, since the heat source for regeneration is the boiling steam of the hot water supply section, no extra regeneration energy is required. In addition, since it can be regenerated every time it is boiled, the frequency of regeneration is increased and the regeneration rate is good. Since the apparatus itself does not need to be separately provided as a reproducing apparatus, it can be compactly stored.

As described above, according to the present embodiment, a water purification container containing activated carbon and having a pore at the bottom, a bottom plate having a pipe through which steam passes, a container for storing water, and heating the water in the container are provided. By providing a hot water supply unit having a heater for heating and a valve for switching the water flow between the water purification unit and the hot water supply unit, harmful components of tap water can be effectively removed for a long period of time, and an energy-saving and compact water purifier with a hot water supply device can be realized.

The difference from the first embodiment is that the switching valve 13 at the time of boiling of hot water is opened to the water use side, and boiling steam enters from the pores of the water purification container 3 through the pipe in the bottom plate 4. The boiling steam heats the fibrous activated carbon 9, desorbs the adsorbed substances, and performs regeneration. At this time, when the control device 21 controls so that the vent valve 5 is not opened until the pressure reaches a pressure slightly higher than the normal pressure, the vent valve 5 is opened when the internal pressure of the container slightly increases. As a result, the substance desorbed from the fibrous activated carbon 9 comes out of the container more quickly, and the regeneration rate increases. If the opening and closing are repeatedly performed, the reproduction efficiency is further improved.

As described above, according to the present embodiment, in addition to the structure of the first embodiment, by providing a control device for opening and closing the ventilation valve, activated carbon can be efficiently regenerated, and the tap water Harmful components can be effectively removed.
