Description

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 in the treatment process. Therefore, it has a strong chlorine odor, and residual chlorine reacts with humic substances and the like to generate trihalomethane harmful to the human body. Furthermore, in the summer, a lot of algae called blue-green algae are generated in the lakes and waters that are raw water, and the water has a musty odor. These events are particularly noticeable in populated urban areas, where water purifiers are used in many homes. These conventional water purifiers have tried to remove these defective components by utilizing the adsorption action of activated carbon.

[0003]

However, in the purification method by activated carbon adsorption, it is very short period of time to effectively remove the bad components in the tap water. Especially in trihalomethanes, the adsorption rate is poor and the desorption is fast, so if used for a certain period or longer, the trihalomethanes adsorbed on the activated carbon will be desorbed, and the concentration will be higher than that of the raw tap water. Therefore, in order to effectively purify water, the activated carbon must be replaced within a very short period of time. Therefore, the regeneration of activated carbon is considered. Since the amount of adsorption of activated carbon decreases as the temperature rises, the difference in adsorption depending on the temperature is used. The substance adsorbed at room temperature is heated to a high temperature to be desorbed and regenerated. However, the activated carbon regeneration rate varies greatly depending on the regeneration means. The adsorption difference due to temperature is large in temperature difference, that is, it is better that the temperature is high, but energy is required to obtain the high temperature. Therefore, if a new heating device is provided for activated carbon regeneration, the entire device becomes large and bulky. In addition, there is a problem that much energy is consumed.

The present invention is intended to solve the above problems, and it is a first object of the present invention to provide a water purifier with a water heater for efficiently regenerating activated carbon and effectively removing defective components for a long period of time. A second object is to provide a water purifier with a water heater using a means for increasing the efficiency of the object, and a water purifier with a water heater with the means for making the first and second objects more effective. The third purpose 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, the first means is to pass steam to a water purifying vessel having activated carbon and having pores at the bottom. It is provided with 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 the water flow between the water purification unit and the hot water supply unit.

As a second means, in addition to the first construction, a control device for opening and closing the vent valve with a certain pressure is provided.

As a third means, in addition to the first and second structures, a blade for stirring 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 the water is heated, which effectively removes the bad components in the tap water for a long period of time. You can get delicious water or hot water.

According to the second structure, the heating steam used for regenerating the activated carbon retains boiling steam by closing the ventilation valve, and when the ventilation valve is opened when a slight pressure is applied, a substance separated from the activated carbon is stored in the container. It's easier to get out of, and as a result the regeneration rate is better.

According to the third structure, the activated carbon is stirred, the specific surface area is effectively utilized, and the adsorption is effectively performed. Also, during regeneration, the desorption is effectively performed by stirring, and the heat is quickly transferred to the entire activated carbon, so that the regeneration is efficient.

Is a heater for heating the water in the water storage container 2, and 7 is a temperature sensor for sensing the water temperature in the water storage container 2. 8 is a tap water inlet, 9 is a fibrous activated carbon for water purification (felt-like finely chopped), 10 is a hollow fiber membrane for water purification, 1
Reference numeral 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 as it is. Reference numeral 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 is a pipe for sending room temperature purified water to the water storage container 2, 18 is an intake for taking boiled hot water, 19 is a pump, and 20 is a pipe.

The operation of the water purifier with a hot water supply device constructed as described above will be described with reference to FIG. First,
Tap water enters the purified water 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 the pump 11 through the pipe 12 to the switching valve 13. When using water, it flows through the pipe 14 from the switching valve 15 to the water outlet 16. Further, when adding water 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, if a switch not shown in the figure is turned on, the pump 19 operates and hot water flows from the water intake 18 through the pipe 20 to the outlet 16 through the switching valve 15. The switching valve 15 can be switched between water and hot water by a switch not shown in the figure. Further, the boiling water switching valve 13 is opened to the water use side, and boiling steam enters from the fine holes of the water purification container 3 through the pipe in the bottom plate 4. The boiling steam heats the fibrous activated carbon 9 to desorb the adsorbed substance and regenerate it.

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

The difference from the first embodiment is that when the boiling water is boiled, the switching valve 13 is opened to the side where water is used, 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 to desorb the adsorbed substance and regenerate it. At this time, if 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 rises slightly. As a result, the substance desorbed from the fibrous activated carbon 9 will come out of the container more quickly, and the regeneration rate will increase. If the opening and closing are repeated, the regeneration efficiency is further improved.

As described above, according to this embodiment, in addition to the structure of the first embodiment, by providing the control device for opening and closing the ventilation valve, the activated carbon can be efficiently regenerated and the tap water can be used for a long period of time.
