である。[Problems to be Solved by the Invention] However, if the tap water valve is operated while the "raw water / purified water" switching lever is set to the purified water side, the entire electronic circuit is always operated even when the water purifier is not used. Since the electric power is supplied, the electric power consumption increases, and as a result, it becomes necessary to frequently replace the internal battery. Such battery replacement is very troublesome, and also poses a risk of electric shock in view of the installation environment of the water purifier. In addition, the structure of the water purifier itself becomes difficult because it facilitates the battery replacement work and at the same time maintains the water resistance of the battery replacement part, resulting in an increase in the cost of the water purifier. Therefore, an object of the present invention is to provide a water purifier having such a filter material exchange display function, which does not require battery replacement at its power source.

Further, the signal processing unit 30 converts the flow rate signal generated by the purified water detecting unit 20 into a quantitative signal such as a pulse signal to continuously calculate the integrated value of the purified water amount. This integration operation starts when the filter medium is installed in the water purifier, and a replacement signal is generated when the integrated value corresponding to the replacement time of the filter medium is reached. Incidentally, the purified water detection unit 20 and the signal processing unit 30 may be mechanically integrated, for example, when a suitable gear mechanism is driven by the water flow in the water purifier as a power, and when it is time to replace the filter medium. The exchange signal may be generated by driving an appropriate switch.

Further, the charging section 52 is provided with an overcharge prevention circuit 54, for example, when the output voltage of the power supply section 50 reaches a value corresponding to the saturation voltage of the storage battery, the power supply control section 60 causes the overcharge prevention circuit 54 to operate. An overcharge prevention signal is sent to and the charging operation of the storage battery is suppressed.

In, the power generation unit 51 is configured by connecting a plurality of solar battery cells 52 in series and parallel to each other on the upper surface of the water purifier. As a result, the electromotive force generated in each solar battery cell 52 is superposed, so that a comparatively high voltage power can be obtained. This electric power is supplied to the charging unit 53 to charge each storage battery of the power storage unit 54.

The constant voltage circuit 73 is formed by the 71 and the capacitor 72, etc., and the power is supplied from the power generation unit 51 to the input terminals C1 and C2 of the constant voltage circuit 73 to provide charging power of a constant voltage between the charging terminals C3 and C4. .

It is formed in any one of a serial connection, a parallel connection, and a serial / parallel connection. For example, switches X N and Z N
Are all driven in the conductive state and all the switches Y N are driven in the non-conductive state, the respective storage batteries are formed in parallel. The connection form of such a storage battery is determined in the power supply control unit 60.

維持される。The power supply control unit 60 normally continuously monitors the output voltage of the power supply unit 50 by using several thresholds, and when the output voltage of the power supply unit 50 decreases, the connection form of the storage batteries G N is connected in series. When the output voltage rises, the connection form of the storage batteries G N is changed to the parallel direction to suppress the output voltage rise. Therefore, each threshold value is preferably set based on the connection form of the storage battery, whereby the output voltage of the power supply unit 50 is always maintained in an appropriate range.

が、電源部50の出力電圧は高くなる。For example, when all the storage batteries G N have been sufficiently charged and then the surroundings of the water purifier become dark and the charging action deteriorates,
Since the integrated value is normally displayed in the water purifier, the output voltage of the power supply unit 50 gradually decreases. When the output voltage of the power supply unit 50 reaches the lower value of the above range with the passage of time, the power supply control unit 60 collectively outputs the connection switching signal c to the power storage unit. As a result, in the power storage unit 54, the connection form of each storage battery G N is changed from parallel connection to serial-parallel connection. As a result, the storage battery capacity of the entire power storage unit decreases, but the output voltage of the power supply unit 50 increases.

Be changed. After that, the dark state continues, and for example, when the output voltage of the power supply unit 50 drops to a predetermined value within the above range or lower, the power supply control unit 60 provides the voltage drop signal d to the signal processing unit 40 and generates it. The power is supplied only to the minimum necessary parts for indicating the replacement of the filter media, such as storage of the integrated value of the purified water volume.

動作を抑止する。On the contrary, when the area around the water purifier becomes bright and each storage battery G N is charged, the power supply control unit 60 is connected every time the output voltage of the power supply unit 50 reaches the upper value of the above voltage range. The switching signal c is generated, and the connection form of the storage batteries is changed in the order of serial connection, serial / parallel connection, and parallel connection. But,
When the output voltage of the power supply unit 50 reaches a voltage equivalent to the saturation state of the storage battery in the parallel connection in which the overall storage battery capacity is maximum, the power supply control unit 60 sends the overvoltage prevention signal e to the charging unit. The charge is supplied to the switch Se to suppress the charging operation of each storage battery G N.

全性をも提供することができる。As described above, according to the present invention, a solar cell is provided on the surface of a water purifier used in a bright environment at least during use, and the electromotive force of the solar cell is used as a power source. The replacement of the filter medium can be displayed without requiring an external power source including the battery for use. Further, since the electric power generated by the solar cell is configured to be stored in the storage battery having a plurality of connection forms, the replacement display operation of the filter medium can be sufficiently compensated even if the surroundings of the water purifier are dark for a long time. . Therefore, it is possible to realize a water purifier that is structurally compact at low cost, and avoid all electric shock accidents and water damage to the inside of the water purifier that can be expected when changing batteries, so that the water purifier can be installed. Safety can also be provided under circumstances.
