(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is an explanatory view showing an installation state of the automatic faucet device 10 in the present embodiment. The automatic faucet device 10 according to the present embodiment is installed in a wash basin A such as a hospital room or a toilet in an office. Either the water that is the first water discharge or the hot water of the second water discharge can be automatically discharged from the water discharge port 22.

  As shown in FIG. 1, the faucet body B of the automatic faucet device 10 is disposed on the washstand A. The faucet body B is formed in a substantially inverted U-shape, and its base end is attached to a horizontal place at the back of the washstand A, and a spout that discharges water toward the washstand A at the front end. 22 is formed. In addition, a sensor 14 that detects an operation of the user inserting a hand below the spout 22 is disposed below the tip of the faucet body B.

  In the present embodiment, the automatic faucet device 10 uses the first water discharge as water and the second water discharge as hot water. However, the first water discharge selectively discharged from the water discharge port 22, The type of water discharge of 2 is not necessarily limited to water and hot water, it is not limited to water and hot water, the water flow rate is large or small, hot water temperature difference, temperature control and flow control, or automatic water faucet device that can discharge alkaline water As such, it can be made strong or weak in alkalinity. Furthermore, it is good also as those combination, and it should just select at least 2 types of water discharge and can discharge.

  Further, as shown in FIG. 1, an operation unit C is provided at a position close to the faucet body B to select either water or hot water by a switch operation and discharge water. FIG. 2 is a plan view showing the configuration of the switch of the operation unit C. FIG.

  As shown in FIG. 2, the operation unit C has three push button type operation switches arranged in parallel, and the first operation switch on the faucet body B side switches to water by a push operation. A switch 15 (first water discharge setting unit). Moreover, the 2nd operation switch arrange | positioned in the center is the hot water switch 23 (2nd water discharge setting part) which switches to hot water by pushing operation. Further, the third operation switch on the side opposite to the faucet body B is a manual water discharge switch 24. For example, when storing water, the manual water discharge switch 24 is pushed and operated to hold the hand over the sensor. The water can be forcibly discharged from the water outlet 22 or stopped.

  The water changeover switch 15 (first water discharge setting unit) is set so that water can be discharged from the water discharge port 22 by a push operation, and when water can be used, a water usage indicator located above the water changeover switch 15. The LED 19 is turned on for display.

  The hot water changeover switch 23 (second water discharge setting unit) is set to enable hot water to be discharged from the water discharge port 22 by a push operation. When hot water can be used, a water usage indicator located above the hot water changeover switch 23. The LED 20 is turned on for display.

  FIG. 3 is a block diagram illustrating a configuration of a main part including the control unit 11 of the automatic faucet device 10 according to the present embodiment. As shown in FIG. 3, the automatic faucet device 10 is composed of an input unit and an output unit with a control unit 11 having a CPU 12 as a center.

  The control unit 11 mainly includes a microprocessor, a memory unit 13 (EEPROM), an input / output interface, and the like.

  The input unit includes a sensor 14 that detects the behavior of the user's hand, a water changeover switch 15 as a first water discharge selection unit, a hot water changeover switch 23 as a second water discharge selection unit, and a power input unit 16. is doing.

  As described above, the sensor 14 detects the behavior of the user's hand on the washstand A and generates a detection signal. The automatic faucet device 10 transmits a detection signal detected by the sensor 14 to the control unit 11 described later, and the control unit 11 that has received the detection signal receives the water supply side electromagnetic valve 17 or the hot water supply side electromagnetic valve 18 described later. And water or hot water is discharged from the water outlet 22.

  As described above, the water changeover switch 15 and the hot water changeover switch 23 are disposed in the operation portion C in the vicinity of the faucet body B (see FIGS. 1 and 2).

  In this embodiment, the power input unit 16 is a plug that is plugged into an AC 100V outlet. By inserting the plug into the AC 100V outlet, the automatic faucet device 10 is turned on.

  The output unit is driven by a command from the control unit 11 to discharge water from the water discharge port 22, and a water supply side electromagnetic valve 18 that discharges hot water whose temperature is adjusted to a predetermined temperature from the water discharge port 22. The water use display LED 19 and the hot water use display LED 20 are provided.

  The water supply side electromagnetic valve 17 is opened by a drive command from the control unit 11, thereby supplying water from the water supply pipe to the water discharge port 22 and allowing the water to be discharged from the water discharge port 22. The hot water supply side electromagnetic valve 18 is opened by a drive command from the control unit 11 to supply hot water in which water and hot water are mixed at a predetermined ratio to a faucet body B by a hot water mixing valve (not shown). The hot water can be discharged from the water port 22.

  With the above configuration, the automatic faucet device 10 receives the detection signal of the sensor 14 and drives the water supply side electromagnetic valve 17 to discharge water from the water outlet 22 or drives the hot water supply side electromagnetic valve 18. The hot water is discharged from the water outlet 22.

  Moreover, the control part 11 can perform the automatic water discharge process by priority water discharge mode. In the priority water discharge mode, when the presence of a user is detected by the sensor 14, either water or hot water is set regardless of the setting state of the water switch 15 or the hot water switch 23 at the end of the previous water discharge. This mode gives priority to water discharge.

  For this purpose, the memory unit 13 of the control unit 11 uses an electrically rewritable EEPROM. For example, priority is given to either water or hot water for each unit setting time set in one-hour intervals. Water discharge information is stored. In the priority water discharge mode, either water or hot water is discharged from the water outlet 22 based on the priority water discharge information written in the memory unit 13. At the time of shipment (default state), the priority water discharge information stored in the memory unit 13 is set so that the priority water discharge within all unit setting times is water.

  In such a configuration, the feature of the automatic faucet device 10 in the present embodiment is that it is possible to execute a priority period setting process in which water or hot water is preferentially discharged at regular intervals and set in advance. is there.

  Here, the priority period setting process preliminarily sets in advance the priority water discharge of either water or hot water for each predetermined period in the priority water discharge mode on the condition that a predetermined priority setting start trigger is detected. It is processing. And the automatic faucet device 10 of this embodiment can set the said priority period setting process by pushing operation of the water changeover switch 15 or the hot water changeover switch 23 by manual operation.

  Thus, the control part 11 with which the automatic faucet apparatus 10 which concerns on this embodiment is equipped with is the water switching as a 1st water discharge setting part at the time of the last water discharge end, if a user's predetermined | prescribed operation | movement is detected by the sensor 14. Regardless of the setting state using the hot water changeover switch 23 as the switch 15 or the second water discharge setting unit, it is possible to execute the automatic water discharge process in the priority water discharge mode for preferentially discharging water or hot water, The said control part 11 performs the priority period setting process which presets the water discharge kind for every fixed period in the said priority water discharge mode on condition that the predetermined priority setting start trigger was detected, the said water change switch 15 or the hot water change switch It can be executed based on 23 operations.

  Moreover, the said fixed period is made into the unit priority water discharge period corresponding to the frequency | count of pushing operation of the water switch 15 or the hot water switch 23 which is a water discharge setting part on a one-to-one basis. In this embodiment, this unit-priority water discharge period corresponds to one hour of pressing operation of the water changeover switch 15 or the hot water changeover switch 23. Therefore, if the number of operations is 24, the priority period setting process can be performed throughout the day. The unit priority water discharge period is not necessarily limited to 1 hour, and may be set as appropriate, such as a 2-hour unit, a 3-hour unit, or an 8-hour unit. In that case, the number of pressing operations of the water changeover switch 15 or the hot water changeover switch 23 is naturally reduced.

  In the priority period setting process, the control unit 11 defines the period set according to the number of operations of the water changeover switch 15 or the hot water changeover switch 23 and the operated water and hot water changeover switches 15 and 23. The water discharge type (water or hot water) to be performed is stored in the memory unit 13 (EEPROM) as priority water discharge information indicating the water discharge type to be prioritized in the unit priority water discharge period (1 hour or 30 days).

  Thus, since the automatic water faucet device 10 according to the present embodiment sets the priority water discharge by pushing the water and hot water switch 15 and 23 in advance, each time the user uses the water and hot water switch, Since the frequency | count of operating 15 and 23 can be reduced, usability improves. Moreover, since the preferential water discharge can be set using the existing water and hot water changeover switches 15 and 23 provided in advance in the automatic faucet device 10, the configuration of the automatic faucet device 10 does not become complicated.

  By the way, when performing a priority period setting process, it is conditional on the control part 11 detecting a predetermined priority setting start trigger.

  In the present embodiment, the priority setting start trigger is a signal indicating that the water changeover switch 15 and the hot water changeover switch 23 are simultaneously pressed and operated. When the control unit 11 detects such a signal, the priority period setting process is performed. Is accepted. In addition, as a priority setting start trigger, it is good also as detecting the long press signal of the manual water discharge switch 24, for example, and operation by the operation part C with which the automatic water faucet apparatus 10 is equipped beforehand may just become a priority setting start trigger. .

  The above-described priority water discharge mode is started when the plug as the power input unit 16 is inserted into an AC 100V outlet and the automatic faucet device 10 is turned on. Accordingly, the priority water discharge mode can be started without the user being aware of it, which is convenient.

  Hereinafter, the procedure of the priority period setting process in the present embodiment will be specifically described with reference to the drawings. FIG. 4 is an explanatory diagram showing a processing flow of a priority period setting process in which the automatic water faucet device 10 according to the present embodiment can set the priority water discharge every hour in one day. In the process in FIG. 4, it is assumed that the automatic faucet device 10 is in a power-on state.

  As shown in FIG. 4, the control unit 11 first determines whether or not there is an input of a setting start trigger to the priority water discharge mode (the water changeover switch 15 and the hot water changeover switch 23 are pressed and held) (step S11). ) If a setting start trigger is input, the process shifts to the priority period setting mode in step S12, and enters the priority period setting acceptance state by manual setting. On the other hand, when there is no setting start trigger input, the process proceeds to step S20, and a priority water discharge mode based on the already set priority water discharge or a water discharge process based on the default priority water discharge is performed.

  In the priority period setting process according to the present embodiment, the priority water discharge information indicating the type of priority water discharge corresponds to one frame to 24 frames in a one-to-one correspondence with the unit setting period “1 hour”. Are stored in the memory unit 13 as a table like a setting table denoted by reference numeral 100. That is, a flag for priority water discharge information for water priority or hot water priority is set in each frame. In the default state (factory shipment state), all 1 to 24 frames are given priority to water.

  Accordingly, when the mode is shifted to the priority period setting mode in step S12, the control unit 11 develops a 24-frame setting table in which one hour corresponds to one frame in the memory unit 13 in step S13, and the water changeover switch 15 or With the first push operation of the hot water switch 23 as a starting point, for example, when the hot water switch 23 is pushed for the first time, priority water discharge information that sets “hot water” as the priority water discharge is set in one frame (step S14). When the switch 15 is pressed, priority water discharge information for setting “water” as the priority water discharge is set (step S15). When the processing from step S13 to step S15 is repeated N times, priority water discharge for N frames is set in the setting table 100.

  In step S <b> 16, the control unit 11 determines whether or not the number of pressing operations of the water changeover switch 15 and the hot water changeover switch 23 has reached a predetermined number of times (N = 24). If it is determined that the button has been pressed 24 times, it is determined that the setting has been completed, and the priority period setting process is terminated.

  In this case, when the total number of operations of the water changeover switch 15 and the hot water changeover switch 23 reaches a predetermined 24 times corresponding to 24 hours, the superior priority period process is completed. 15 and the hot water changeover switch 23 are counted, and the setting is completed when the number of operations exceeds 24. Therefore, the setting of the priority period setting process can be performed easily and reliably.

  On the other hand, when it has not reached 24 times yet, the time for which the water changeover switch 15 or the hot water changeover switch 23 is pushed is measured, and it is determined whether or not one minute has passed without being pushed (step S17). . If the push operation is performed before 1 minute elapses, it is determined that the priority water discharge of the N frame is set by the push operation of the water changeover switch 15 or the hot water changeover switch 23 described in step S14 and step S15. Then, it increments as N = N + 1 (step S19), the processing of step S13 and step S14 or step S15 in the N + 1 frame is performed, and either water or hot water in the N + 1 frame is set, and again in step S16 Move on to processing.

  If the controller 11 determines in step S17 that one minute has passed without the water switch 15 or the hot water switch 23 being pushed, the process proceeds to step S18, where the water switch 15 and the hot water switch 23 are switched. Even if the total number of operations is less than the predetermined 24 times, the remaining period corresponding to the number of times obtained by subtracting the total number of operations from 24 times is the last time the water changeover switch 15 is operated. Or the water or hot water corresponding to the water discharge setting part different from the hot water changeover switch 23 is stored in the memory part 13 as the priority water discharge, and the priority automatic setting mode is completed.

  That is, in the process of step S17, when one minute has elapsed when the number of operations is less than 24 times, the control unit 11 completes the setting and sets the water changeover switch 15 and the hot water changeover switch 23. Since it is determined that the operation will not be performed in the future, the priority water discharge in all the frames up to 24 frames after the N frame is set as the priority water discharge opposite to the water discharge type set in the N frame. is there.

  For example, when one of the water and hot water changeover switches 15 and 23 is operated 12 times in order and one minute has passed without the switch operation after the 13th frame being performed, the water and hot water switching is performed until the 12th frame. Depending on the operation of the switches 15 and 23, water or hot water is set as the priority water discharge, but from the 13th frame to the 24th frame, the discharge type opposite to the 12th priority water discharge last set is stored as the priority water discharge. Is done. For example, if the water discharge type set in the 12th frame is “hot water”, “water” is set as the priority water discharge in the 13th to 24th frames.

  Thus, according to the present embodiment, the priority period for one day can be set without performing the pushing operation of the water and hot water changeover switches 15 and 23 all 24 times. That is, it is also possible to set the priority water discharge in an appropriate period according to the number of operations and omit the subsequent setting operation. Accordingly, the number of setting operations using the water / hot water changeover switches 15 and 23 can be reduced.

  As described above, in the priority period setting process in the present embodiment, starting from the first pressing operation of the water changeover switch 15 or the hot water changeover switch 23, the control unit 11 determines whether the water changeover switch 15 or the hot water changeover switch 23 is active. Each time the push operation is performed, the priority water discharge information based on the order and the number of times of pushing the water changeover switch 15 and the hot water changeover switch 23 is sequentially rewritten in 1 to 24 frames which are all water-priority in the default state. Can be remembered.

  For example, if the water selector switch 15 is pressed in the first, the water selector switch 15 is pressed in the second, and the hot water selector switch 23 is pressed in the third, the water in the first frame of the setting table 100, the water in the second frame, the third frame Then hot water is determined as the priority water discharge. Thus, priority water discharge is set in the frame order of the setting table 100 in the order in which either the water changeover switch 15 or the hot water changeover switch 23 is pushed. Whether water or hot water in the frame is to be preferentially discharged is determined by selection of the water switch 15 or the hot water switch 23 corresponding to the frame order.

  More specifically, if the priority time setting mode is entered and the hot water changeover switch 23 is first pressed (first time) is 9:15 (hereinafter referred to as “9:15”). For example, during one hour from 9:15 to 10:15 (the first frame of the setting table 100), “hot water” becomes the set water discharge, and the next (second) operation of pressing any one of the switches The water discharge type corresponding to the type is priority water discharge up to 10:15 to 11:15 (second frame of the setting table 100). For example, when the water changeover switch 15 is operated, “water” is set as the priority water discharge for one hour from 10:15 to 11:15 (second frame of the setting table 100). Thus, after this setting processing, “hot water” is automatically discharged from 9:15 to 10:15, and “water” is automatically discharged from 10:15 to 11:15.

  In this way, priority water discharge information for up to 24 frames of the setting table 100 is determined according to the first to 24th operations of the water changeover switch 15 or the hot water changeover switch 23, and is set to 1 over 24 hours. Priority water discharge every hour can be set at once. In addition, as described above, even if the setting by pressing the water changeover switch 15 or the hot water changeover switch 23 is stopped halfway, the subsequent time zone (the frame of the setting table 100) is automatically set, and the priority after the setting is made. Since it will be reflected in water discharge, setting operation will not be troublesome. If it is desired to always use “hot water”, only the hot water switch 23 needs to be operated 24 times.

  After the setting, the water discharge type set in units of one hour is automatically discharged preferentially until a new setting is made.

  If the setting is made by mistake, in the present embodiment, the water changeover switch 15 and the hot water changeover switch 23 can be reset again by simultaneously pressing and holding them again. After resetting, it can be set again according to the processing flow in FIG. Note that when a predetermined time elapses after resetting, the default state may be restored. For example, after setting the priority water discharge period, if you change your mind and want to always set it to “water”, you can wait for a predetermined time after resetting.

  As described above, in the automatic water faucet device 10 according to the present embodiment, once the priority period is set and the priority water discharge setting for every 24 hours is performed at once, the automatic water faucet device 10 is based on the priority water discharge information set for each time. Since automatic water discharge is repeated thereafter, it is very convenient to use because it saves the trouble of setting every day.

  By the way, in the priority period setting process described above, when the water changeover switch 15 or the hot water changeover switch 23 is pressed to set the priority water discharge information in the unit setting period (1 hour), the push operation is accepted. Can be confirmed by the setter. That is, when the water changeover switch 15 or the hot water changeover switch 23 is received, the control unit 11 lights or blinks the water use display LED 19 or the hot water use display LED 20 provided in the operation unit C. When water is set to priority discharge in the Nth operation (N frame), the water use indicator LED 19 is lit and the setter can confirm that water has been set as priority discharge in that frame. .

  When the priority period setting is completed, the control unit 11 can notify the setter of the priority water discharge information set in the 1 to 24 frames of the setting table 100 according to the priority water discharge information. The use display LEDs 20 are sequentially turned on.

  That is, from one frame of the setting table 100 to 24 frames in order, the water use display LED 19 or the hot water use display LED 20 is turned on according to the priority water discharge information set in each frame. For example, if the priority water discharge of one frame is “hot water”, the hot water use display LED 20 is turned on. If the priority water discharge of two frames is “water”, then the water use display LED 19 is turned on. -The water use display LED 19 or the hot water use display LED 20 lights in order of 24 frames. Thus, since the setting result can be confirmed immediately after the setting of the priority period, the setter can reliably perform the priority period setting process.

  In the first embodiment described above, the unit-priority water discharge period is set to 1 hour, so that the automatic faucet device 10 does not have a time counting function for recognizing time in particular. Preferential water discharge can be set finely every hour within one day from the time when is pressed for a long time.

(Second Embodiment)
Below, the 2nd Embodiment of this invention is described, referring FIG. FIG. 5 is an explanatory diagram showing a processing flow of priority period setting processing of the automatic faucet device according to the second embodiment.

This embodiment is different from the first embodiment in that the unit setting period is 30 days instead of 1 hour.
As shown in FIG. 5, 1 to 12 frames are set in the setting table 101 used here, and preferential water discharge information indicating the type of preferential water discharge is stored in association with each frame. That is, from 1 frame to 12 frames can be set in a one-to-one correspondence with “about 30 days” which is the unit setting period in the present embodiment, and monthly priority water discharge can be set all over the year. It has become.

  In FIG. 5, the control unit 11 first determines whether or not there has been an input of a setting start trigger for shifting to the priority water discharge mode (step S21), and if there has been an input of a setting start trigger, the process proceeds to step S22. If the process is shifted and there is no input, the process shifts to step S30 to shift to a mode without the priority water discharge mode to perform the water discharge process. Also in this case, the priority setting start trigger is that the control unit 11 detects a signal in which the water changeover switch 15 and the hot water changeover switch 23 are simultaneously pressed for a long time.

  When shifting to the priority period setting mode in step S22, the control unit 11 develops a setting table of 24 frames in which 30 days correspond to one frame in the memory unit 13 in step S23, and the water changeover switch 15 or the hot water switch 15 Starting from the first push operation of the changeover switch 23, for example, when the hot water changeover switch 23 is first pushed, priority water discharge information for setting “hot water” as the preferential discharge is set in one frame (step S24). When 15 is pushed, priority water discharge information with “water” as the priority water discharge is set (step S25). When the processing from step S23 to step S25 is repeated N times, priority water discharge for N frames is set in the setting table 101.

  In the memory unit 13 (EEPROM), water is given priority in the default state, and water is discharged preferentially in all frames from 1 to 12 in the setting table 101.

  Next, in step S26, the control unit 11 determines whether or not the total number of operations of the water changeover switch 15 and the hot water changeover switch 23 has reached a predetermined number of times of 12 (N = 12) (step S26). S26). If the button is pressed 12 times, it is determined that the setting is completed, and the priority period setting process is terminated.

  In this way, the priority automatic setting mode is automatically completed when the total number of operations of the water changeover switch 15 and the hot water changeover switch 23 reaches twelve predetermined times. By simply counting the number of operations, the priority period setting process can be set easily and reliably.

  On the other hand, in the step S26, when the push operation is not performed up to 12 times, the time during which the water changeover switch 15 or the hot water changeover switch 23 is pushed is measured, and whether or not one minute has passed without being pushed. Judgment is made (step S27). If there is a push operation before 1 minute has elapsed, it is determined that priority water discharge has been set in the N frame, and N is incremented as N + 1 (step S29). Then, the processing in step S23 and step S24 or step S25 in the N + 1 frame is performed, and when either water or hot water in the N + 1 frame is set, the process proceeds to step S26.

  If the controller 11 determines in step S27 that one minute has passed without the water switch 15 or the hot water switch 23 being pushed, the process proceeds to step S28, where the water switch 15 and the hot water switch 23 are switched. Even if the total number of operations is less than the predetermined 12 times, the remaining period corresponding to the number of times obtained by subtracting the total number of operations from 12 times is the water switch 15 that has been operated last. Or the water or hot water corresponding to the water discharge setting part different from the hot water changeover switch 23 is stored in the memory part 13 as the priority water discharge, and the priority automatic setting mode is completed.

  That is, in the process of step S27, when one minute has elapsed when the number of operations is less than 12 times, the control unit 11 determines that the water changeover switch 15 or the hot water changeover switch 23 will not be operated in the future. The priority water discharge in all the frames up to 24 frames after the N frame is set as the priority water discharge opposite to the one set in the N frame.

  Thus, in the second embodiment, since the unit priority water discharge period is about 30 days, even if the automatic faucet device is not equipped with a calendar function, the priority water discharge according to the season is set throughout the year. can do.

  For example, if the priority period setting process is performed on January 1, if any one of the water and hot water changeover switches 15 and 23 is operated 12 times in order, the setting is made approximately every month from this setting time point through about one year. The water discharge type (water or hot water) according to the contents is automatically discharged. In this setting process, when the water and hot water switch 15 and 23 are sequentially pressed and the water switch 15 is pressed for the 10th time and left for one minute or longer, the 11th and 12th frames have “ Priority water discharge information corresponding to “hot water” is stored. That is, about November and December, “hot water” is automatically discharged.

  As described above, since the automatic faucet device 10 according to the present embodiment can set the priority water discharge every month for approximately one year in advance according to the user's preference, There is no need to switch the setting to hot water, making it easier to use. Also in this case, since the priority water discharge can be set by using the existing water and hot water changeover switches 15 and 23 as they are in the automatic faucet device 10, the automatic faucet device 10 is not complicated.

  As described above, the present invention has been described through the preferred embodiments. However, the configuration can be changed as appropriate without departing from the spirit of the invention. For example, the configuration of the automatic water faucet device 10 can be changed as appropriate. Also, the unit priority water discharge period can be set as appropriate even in the period in which the set priority water discharge is performed.
