The initializing operation reads a time of the clock 813 and calculates a date and displays the date and time on the date/time window 821, displays how is a state (a state of remaining amount of the filtered water) of the sensors 612, 613 for grasping the filtered water condition within the filtered water container 6, and the micom 815 displays the state display of the control board as these so as to be matched to a changed condition also at the main loops of the program after the initialization. the micom 815 reads a value of the cleaning cycle variable from said main program and compares with the cleaning cycle value (in the embodiment, 48 hours in winter, 24 hours in other seasons, which are a time band having no filtered water demand; or it can be varied In accordance with.the environmental temperature) given by the program, and when it has come to the cleaning cycle, the cleaning cycle variable is initiali- zed and then a 'cleaning mode' is progressed, and when it is not, the cleaning cycle variable is incremented. The micom 815 reads a value of a delivering water cycle variable from said program and compares with a delivering water cycle value (in the embodiment, a time band having no filtered water demand every day) given by the program, and when it has come to the delivering cycle, the delivering water cycle variable is initalized and then a 'circulating mode' is progressed, and when it is not, the delivering water cycle variable is incremented. The micom 815 reads a sterilizing cycle from said main loop, and when compares with a sterilizing cycle value (approximately 30 minutes) given by the program, and when it has come to the sterilizing cycle, the sterilizing cycle is initialized and then a lamp lighting on signal is transmitted and the ultra-violet lamp 615 is lighted on for a predetermined time period (approximately 5 minutes) whereby a sterilization of the filtered water within the container 6 is executed.

The micom 815 reads a state of the water pressure sensor 612 from the main loop of said control program, ε. ~d when a low water level state LI of the filtered water, transmits a pump 3 driving signal to the drive 3' whereby turns on the power of the pump 3. When the pump 3 is deiven, the micom 815 returns to the main loop and then turns on/off the pump 3 in accordance with next two kinds conditions. that is, when the water pressure sensor 612 is a high water level state 12, a driving of the pump 3 is made to be stopped. When the water sensor 612 is not a high water level state L2 and simultaneously the ^r;ater level sensor 211 of the filtering tank 214 detects a water, the driving of the pump 3 is made to be stopped for a moment.

The micom 815 transmits a water supply valve 212 opening signal to the drive 212' together with said pump 3 on signal transmitting, and transmits a water supply valve 212 closing signal together with the pump 3 off signal. when the original water 250 is supplied to said filtering tank 214, a filtered water passed through the ceramic filter 234 is transferred to next equipment. through the water passing pipe 233 and the guiding pipe 231, a dirt and mud containing filtered water of a part is wasted to the drain line 242 through the drain 413, the complex processor 5 supplied with the filtered water makes to contact the filtered water to the activated carbon, the ion exchange resin, and the permanent magnet and sends to next equipment, and the filtered water passed through said equipments is stored to the container 6 and supplied at a time of the filtered water demand, and dirculated again for filtering or drained.

In case when the micom 815 reads the sensor 112 on signal and a cup 111 is appeared at beneath the discharging pipe 715 of the filtered water supply chamber 11, or when the filtered water supply demand Is grasped from the function selecting key 823-1 of the control board 824, executes a filtered water supply mode .

At the filtered water supply mode, ^"the micom 815 transmits a port 713-1 opening signal of the valve 713 and a pump 711 driving signal to the drives 713', 711' whereby supplies the filtered water within the container 6 to the cup 111 through the discharge pipe 715, and when a filtered water supply stop condition is given, it transmits the port 713-1 close signal of the valve 713 and the pump 711 stop signal whereby stops the supply of the filtered water.

The micom 815 checks whether or not the sensor 112 off signal that the cup 11 is not detected with the filtered water supply stop condition or a filtered water supplying time period (in the embodiment, a time period becoming to a cup amount is approximately 2 seconds) given by the program from a filtered water supply time point are elapsed, and when these conditions are satisfied, the supply of the filtered water is made to be stopped as above. In said filtered water supplying process, it will be happened a case spilling a small amount of the filtered water to the grill 14, and the spilled filtered water is wasted through the drain equipment 13 and the drain line 242. At said 'cleaning mode', the micom 815 progresses the 'cleaning step', 'water cleaning step¹ and the 'draining step¹ whereby clearly eliminates the piled dirt and mud on the ceramic filter 234 surface.

At said cleaning step, the micom 815 outputs a cleaning motor 236 driving signal to the drive 236' and then waits a time period of cleaning time (approximately 5 minutes in the embodiment) given by the program and stops the driving of the cleaning motor 238 and progresses the main teop.

The rotating power of said cleaning motor 236 is borne to the water tight supporter 230 through a transferring system made by the belt 238 and the pulley 235 whereby rotates the water passing pipe 233 connected to the guiding pipe 231 of the water tight means 232. The rotation of the water passing pipe 233 makes the ceramic filter 234 to be made with a friction wherebv separates the dirt and mud piled on the surface.

At said water cleaning step, the micom 815 outputs an operating signal to the dlrves 212", 222', 216' and executes a cleaning operation as below, and waits a cleaning time period (approximately 5 minutes) given by the program and progresses a draining step.

At said cleaning operation, the micom 815 closes (considering an opened case) and opens the drain valve 222 and the water cleaning valve 216. When said water cleaning operation is started, a water supplied from the water cleaning water supply pipe (which is connected to the service pipe) is spouted out from the water cleaning nozzle 215 whereby water cleans the interior of the ceramic filter 234 and the filtering tank 214, and the water cleaning water is overflowed the partitioning wall 221 and collected to the drain chamber 220, and drained through the drain pipe 223 connected to the drain line 242.

When these operations are progressed during the water cleaning time period, the filtering tank 214 interior becomes a clean state in proportional to a using time at beginning of the cleaning apparatus.

At said draining step, the micom 815 closes the water cleaning valve 216 and waits a draining time period (approximately 1 minutes) given by the program and makes the valves to return to a state before the cleaming mode and terminates the cleaning mode.

At said circulating mode, the micom 815 operates in following two kind's types in accordance with the designating state of the function key 823-2 of the control board 824.

When the function key 823-2 is set to a 'circulation' (a basic state), the drain valve 222 is opened and the original water within the filtering tank 214 is drained and the drain valve 222 is closed and then, an opening signal of the valve 713 port 713-2 and a driving signal of the pump 711 are transmitted to the drives 713', 711 whereby the filtered water is made to be transferred to the filtering tank 214, and when a state of the water level sensor 612 is grasped and it is a low water level L2, the port 713-2 is closed and a driving of the pump is stopped whereby the filtered water of a part is made to circulate to be filtered again. the filtered water circulated and transferred to said filtering tank is filtered again as an original water whereby cleaned and the. resolved and preserved quantity of oxygen is raised whereby a fresh sense required as a drinking water is promoted.

When a state of the function key 823-2 is a 'drain', an opening signal of the valve 713 port 713-3 and a driving signal of the pump 711 are transmitted to the drives 713', 711 whereby the filtered water within the container 6 is made to be flowed to the drain pipe 717 connected to the drain line 242, and when the micom 815 reads an off signal (no water present signal) of the water detecting sensor 613, the port is closed and a driving of the pump 711 Is stopped whereby the drain of the filtered water is completed.

When the micom 815 receives a ^rset' signal from the function selecting key 823-3 of the control board 824, correction routines such as the cycles, the executing time period, and the date provided by said program are respectively called and executed. And, it is possible to use by adding a cooling device, a heating device and the like of ^'the filtering water being not embodied in this invention, and in this case, the cooled or heated filtered water can be directly utilized.
