Abstract

PURPOSE:To enable multiple changing-over operations of discharged water temperature to be conducted under a less number of operations at an operating part and improve convenience in use by a method wherein the hot water and the fed water are mixed before they reach the water discharging port and then the water is discharged under a specified temperature. CONSTITUTION:When any one of water button 35a, proper hot water button 35b and hot water button 35c is depressed singly, water discharging operation corresponding to that button is carried out. That is, if the operation is the single operation of the proper hot water button 35b, the most appropriate temperature (42 deg.C) for the taking a bath is instructed as a temperature of the discharged hot water, the flow rates of the water and hot water are calculated in response to the temperature and discharged. If either the water button 35a or the hot water button 35c is singly operated, the water is discharged only under the single water or the single hot water operation, respectively. In turn, if the proper temperature hot water button 35b and the water button 35a are concurrently depressed or depressed in sequence, a lower temperature (40 deg.C) than 42 deg.C of the most appropriate hot water temperature is instructed. Flow rates of water and hot water are adjusted in response to the instructed low temperature and the water and hot water are discharged. If the water button 35a and the hot water button 35c are applied, either the eater or the hot water is alternatively discharged under the predetermined period.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spouting device that mixes hot water and feed water while reaching a spout to spout water at a designated temperature.

[0002]

2. Description of the Related Art A water discharge device of this type is equipped with a dial type temperature setting mechanism provided at a water discharge port such as a faucet, as seen in a known hot and cold water mixing faucet. When this dial is rotated to the high temperature side or the low temperature side, the reference position of the wax (temperature sensitive body) is changed by the amount of the rotation, and the water discharge temperature is set accordingly. And
Water is discharged at this set temperature.

In recent years, in place of the above-mentioned wax (temperature sensitive body) type temperature setting mechanism, there has been proposed a technique of setting the discharge water temperature by a button operation in order to electrically change the mixing ratio of hot water. Kaihei 2-71026). In this button operation type temperature setting mechanism, a button for temperature setting is pressed to directly set the water discharge temperature.

[0004]

Generally, since the water spouting device is used in a bathroom, a sink, etc., it is possible to spout water or high-temperature hot water into the water spouting device, and it is also uncomfortable when taking a bath or washing dishes. It is required to be able to spout water by switching from so-called hot water of a suitable temperature (suitable hot water) to hot water or hot water. Moreover, the switching of the discharged water, that is, the switching of the discharged water temperature is frequently performed. For this reason, the following problems have been pointed out in the above conventional water discharge device.

In the water discharger having a dial type temperature setting mechanism, the dial must be rotated every time the water discharge temperature is changed. In this case, if the desired water discharge temperature is greatly different, for example, when changing the water discharge from water to hot water having a higher temperature or suitable water, a dial operation with a large amount of rotation is required. As a result, such a complicated dial operation is required every time the water discharge is changed frequently.

On the other hand, in the water spouting device having a button operation type temperature setting mechanism, although the operation at the time of switching the water spouting is simple because it is a button operation, there are the following problems in setting the water spouting temperature. You may want to slightly change the spouting temperature while spouting hot water for bathing or washing dishes. In order to immediately change the water discharge temperature, a small button dedicated to changing the water discharge temperature is required. As a result, even if the operation itself is a simple button operation, the number of buttons increases, which is complicated. Also, when it is desired to switch the water discharge temperature alternately, the corresponding button must be operated alternately, which is also complicated.

That is, it cannot be said that the conventional water discharger has sufficient usability when switching the water discharge temperature.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to make it possible to diversify the discharge water temperature with a small number of operations of the operation section and to improve the usability.

[0009]

Means for Solving the Problems In order to achieve such an object, the means adopted by the present invention is a discharge water temperature for adjusting the temperature of the discharge water by mixing the supply hot water and the supply water while reaching the discharge outlet. In a water spouting device having an adjusting unit and a spouting water temperature instructing unit for instructing the spouting water temperature adjusting unit to instruct the temperature of the spouting water from the spouting port, the spouting water temperature instructing unit changes the temperature of the supply hot water to the temperature of the supply water. An appropriate temperature instructing operation section for instructing a predetermined temperature as a water discharge temperature, a water instructing operation section for instructing a temperature of the supply water or a temperature close to the temperature as a discharge water temperature, and a temperature of the hot water supply or the temperature. A hot water instruction operating unit that indicates an approximate temperature as the discharge water temperature, and an appropriate temperature decrease that indicates a temperature lower than the predetermined temperature as the discharge water temperature when the appropriate temperature instruction operation unit and the water instruction operation unit are operated within a predetermined time. Indicator and location When the appropriate temperature instruction operation section and the hot instruction operation unit in time is operated, and its gist in that it comprises a suitable temperature increase instruction unit for instructing the predetermined temperature than the temperature higher as the water discharge temperature.

Further, the means adopted in addition to this, the hot water temperature adjusting means for mixing the hot water and the hot water to reach the hot water outlet to adjust the temperature of the hot water, and the hot water temperature adjusting means, In a water discharge device having a water discharge temperature instructing means for instructing a water discharge temperature from a water outlet, the water discharge temperature instructing means indicates a predetermined temperature from the temperature of the hot water supplied to the temperature of the water supplied as a water discharge temperature. An appropriate temperature instruction operation unit, a water instruction operation unit that indicates the temperature of the supply water or a temperature close to the temperature as the discharge water temperature, and a hot water instruction that indicates the temperature of the supply hot water or a temperature close to the temperature as the discharge water temperature Operation part,
When the water instruction operating unit and the hot water instruction operating unit are operated within a predetermined time, the water discharge temperature instructed by the water instruction operating unit and the water discharge temperature instructed by the hot water instruction operating unit are alternately instructed as the water discharge temperature. The gist of the present invention is to provide a hot and cold water alternate instruction unit.

[0011]

In the water discharger having the above structure, when the appropriate temperature instruction operating portion, the water instruction operating portion, and the hot water instruction operating portion of the water discharge temperature instructing means are individually operated to operate, the operating instruction operating portion operates. The discharge water temperature adjusting means is instructed to the discharge water temperature adjusting means, and the discharge water temperature adjusting means mixes the supplied hot water and the supplied water to adjust the discharge water temperature. Then, it is possible to discharge water from the water outlet at the adjusted temperature. That is, when the proper temperature instruction operating unit is operated independently to operate, a predetermined temperature from the temperature of the supplied hot water to the temperature of the supplied water is instructed to the water discharge temperature adjusting means as the water discharge temperature, and water is discharged at this temperature. When the water instruction operating unit is operated independently to operate, the temperature of the supply water or a temperature close to the temperature is instructed to the water discharge temperature adjusting means as the water discharge temperature, and the water is discharged at this temperature. When the hot water instruction operating unit operates independently, water is discharged at the temperature of the hot water supplied or at a temperature close to the temperature.

On the other hand, when both the proper temperature instruction operating portion and the water instruction operating portion are operated within a predetermined time and both instruction operating portions operate, a temperature lower than the predetermined temperature instructed by the proper temperature instruction operating portion is lowered to the proper temperature. The water discharge temperature adjusting means is instructed by the instruction unit, and water is discharged at this temperature. Similarly, when the appropriate temperature instruction operating unit and the hot water instruction operating unit are operated within a predetermined time and both of these instruction operating units are activated, a temperature higher than the predetermined temperature instructed by the appropriate temperature instruction operating unit is increased to the appropriate temperature increasing instruction unit. Then, the water discharge temperature adjusting means is instructed to discharge water at this temperature. As a result, it is possible to switch the spouting water temperature to five types with the three instruction operation units, that is, the appropriate temperature instruction operation unit, the water instruction operation unit, and the hot water instruction operation unit.

Further, the water discharger having a separate structure adjusts the water discharge temperature as described above in accordance with the independent operation of each instruction operating portion of the water discharge temperature indicating means, like the water discharger described above.
Allows water discharge at the adjusted temperature. When both the water instruction operating unit and the hot water instruction operating unit are operated within a predetermined time and both of the instruction operating units operate, the water discharge temperature instructed by the water instruction operating unit and the water discharge temperature instructed by the hot water instruction operating unit Are alternately instructed to the water discharge temperature adjusting means as the water discharge temperature by the hot and cold water alternate instruction section. Therefore, the discharge water temperature adjusting means that receives this instruction,
When adjusting the discharge water temperature by mixing the hot water supply and the water supply, the adjustment temperature is alternately switched. As a result, it is possible to perform simple switching and alternate switching of the water discharge temperature with the three instruction operating sections, the proper temperature instruction operating section, the water instruction operating section, and the hot water instruction operating section.

Next, regarding the water discharge switching control (routine) performed by the water discharger 1 of the present embodiment having the above-mentioned configuration,
A description will be given based on the flowchart of FIG. In addition, when each button such as a water button, a suitable hot water button, and a hot water button is used when explaining the routine, each button (water button 35a, water button 35a, Suitable hot water button 35b, hot water button 35
It is assumed that c) has been operated.

The water discharge switching routine shown in FIG. 4 is repeatedly executed after the power is turned on. First, the initial processing executed only when the power is turned on, that is, the internal register of the CPU is cleared. Then, as shown in FIG. 4, each button (water button 35
It is determined whether or not any one of a, the appropriate hot water button 35b, and the hot water button 35c has been pressed alone (step 10).
0: Hereinafter, the step will be simply referred to as S). If it is determined that one of the buttons has been pressed alone (affirmative determination), the process proceeds to S110, and if the determination is negative, the process proceeds to S200. Note that S100
The negative judgment in (2) is made when two of the above buttons are simultaneously pressed and when two of the above buttons are successively pressed within a predetermined time (for example, within 1 second). It

If an affirmative determination is made in S100, it is subsequently determined whether or not the button pressed alone is the suitable hot water button 35b (S110). And the hot water button 35
When it is determined that b is singly pressed, it is assumed that the optimum temperature for bathing or showering, for example 42 degrees, is designated as the temperature of hot water to be discharged, and the temperature is set to RO.
It is read from M42 (S120). The optimum temperature (water discharge temperature) is preset and stored in the ROM 42 as the temperature of the suitable hot water. When the above determination is made, a control signal is output from the electronic control unit SS to the discharge water temperature setting panel 35 to turn on the LED below the numeral 42 in the display lamp group 35g. The same applies to the water discharge temperature setting panel 37.

Thereafter, the flow rates of water and hot water are calculated based on the temperature of the suitable hot water that has been read (S130). Then, the flow rate adjustment amounts of the flow rate adjusting valves 15 and 17 corresponding to the calculated flow rates, that is, the drive amounts of the actuator 19 and the actuator 21 are obtained, and a drive signal is output to each actuator (S140). Receiving this signal, each actuator is driven and each flow rate adjusting valve adjusts the flow rate, so that the calculated flow rate of water and hot water flows into the merging flow path 23,
A suitable hot water having the above-mentioned water discharge temperature (42 degrees) is discharged from the water discharge destination switched and controlled by the water discharge switching unit 27. In calculating the flow rates of water and hot water (actuator drive amount), in addition to the temperature of the appropriate hot water read, the temperature of the water itself in the inflow pipe 3 and the inflow pipe 5 from the flow rate sensors 7, 9 and the temperature sensors 11, 13 and The flow rate, the temperature of the hot water itself, the flow rate, the water discharge temperature detected by the temperature sensor 25 provided in the merging flow path 23, the adjusted water discharge amount in each of the currant portions 31, 33 or the shower head S, and the like are considered.

The spouting destination determined by the spouting water switching unit 27 is the washing place currant AK if the pressed appropriate hot water button is the button of the spouting water temperature setting panel 35, and the spouting water temperature setting panel 3 is provided.
If it is the 7 button, it will be Bascaran BK. Further, by operating a water discharge destination selection button or the like (not shown) on the operation panel P, it is possible to switch to the shower head S in addition to each of the currants. Further, the switching control of the water discharge destination is interrupted when the suitable hot water button of the water discharge temperature setting panel 35 or the water discharge temperature setting panel 37 is pressed or when the water discharge destination selection button on the operation panel P is pressed. It is processed.

After the water is discharged in this way, each curran portion 3
1, 33 or the shower head S, whether or not the water discharge amount is zero, that is, the water is stopped, or whether or not another button (in this case, the water button 35a, the hot water button 35c) is newly pressed. A judgment is made (S150). Here, if a negative determination is made, it is assumed that the water discharge state up to now is continued, and the processing of S130 and thereafter is repeatedly executed, and if a positive determination is made, the water discharge state up to now is canceled or changed to another water discharge state. The process ends.

On the other hand, if a negative determination is made in S110, the water button 35a or the hot water button 35c other than the suitable hot water button 35b is independently pressed in combination with the determination of the single button operation in S100. It can be judged that it was done. Therefore, in this case, a drive signal is output to each actuator of each flow rate adjusting valve as follows (S16).
0), flow rate adjustment and water discharge are performed.

The button pressed independently is the water button 3.
If it is determined to be 5a, it is determined that the water temperature is instructed as the discharge water temperature, and each flow rate adjustment valve is driven via each actuator. That is, the flow rate of the flow rate adjusting valve 17 in the inflow pipe 5 on the hot water side is zero, and the flow rate of the flow rate adjusting valve 15 in the inflow pipe 3 on the water side is equal to each of the calan parts 31, 3.
3 or a drive signal having a flow rate corresponding to the adjusted water discharge amount in the shower head S is output to each actuator. Receiving this signal, each actuator is driven and each flow rate adjusting valve adjusts the flow rate as described above, so that only water flows into the merging passage 23 and is discharged. When it is determined that the button pressed alone is the hot water button 35c, it is determined that the hot water temperature is instructed as the discharge water temperature, and each flow rate adjustment valve is driven via each actuator. That is, a drive signal is output to each actuator so that the flow rate of the flow rate adjusting valve 15 is zero and the flow rate of the flow rate adjusting valve 17 is a flow rate according to the adjusted water discharge amount in each curran portion or the like. Receiving this signal, each actuator is driven and each flow rate adjusting valve adjusts the flow rate, so that only the hot water flows into the merging flow path 23 and is discharged.

After that, the routine proceeds to S150 and the above-mentioned processing is carried out to end the present routine. The determination in S150 in this case (determination as to whether or not another button has been newly pressed) is as follows. That is, when the water button 35a is operated independently, it is determined whether the hot water button 35c or the suitable hot water button 35b is newly pressed as another button, and when the water button 35c is operated independently,
As another button, it is determined whether the water button 35a suitable hot water button 35b has been newly pressed.

If it is determined in S100 that none of the water button 35a, the appropriate hot water button 35b and the hot water button 35c has been pressed independently, that is, if two of the above buttons are pressed at the same time, Alternatively, if it is determined that two of these buttons have been successively pressed within the above-mentioned predetermined time, the processing from S200 onward is performed. First, S20
0, S210, the combination of the two buttons pressed, the combination of the suitable hot water button 35b and the water button 35a, the combination of the suitable hot water button 35b and the hot water button 35c,
It is continuously determined which one of the combination of the water button 35a and the hot water button 35c.

In S200, the suitable hot water button 35b and the water button 3
If it is judged that 5a and 5a are pressed simultaneously or successively, the above-mentioned optimum temperature (42 degrees) is set as the temperature of the hot water to be discharged.
Assuming that the temperature (40 degrees) lower by about 2 degrees is instructed, the water discharge temperature WT is changed to 40 degrees (S220). At this time, the discharge water temperature setting panel 3 is set from the electronic control unit SS.
5 and the discharge water temperature setting panel 37, a control signal is output to turn on the LED below the numerical value 40 in the display lamp groups 35g and 37g. Further, the change amount (2 degrees) of the water discharge temperature is stored in the ROM 42 in advance.

After that, the flow proceeds to S130, where the flow rates of water and hot water are calculated based on the changed discharge water temperature WT.
The processing of 140 and 150 (driving the flow rate adjusting valve 15 and the flow rate adjusting valve 17, water discharge, water stoppage, determination of necessity of changing the water discharge state, etc.) is performed. In the calculation of the flow rates of water and hot water, as described above, it goes without saying that the flow rates and the detected temperatures from the flow rate sensors and the temperature sensors are taken into consideration. The determination in S150 in this case (determination as to whether or not another button has been newly pressed) is as follows. That is, it is determined whether any one of the water button 35a, the suitable hot water button 35b, and the hot water button 35c is newly pressed alone, and whether the suitable hot water button 35b and the hot water button 35c are newly or simultaneously pressed. To do.

On the other hand, in S220, which is carried out after the negative determination in S200, the suitable hot water button 35b and the hot water button 35c.
If it is judged that and are pressed at the same time or one after another, the temperature of the hot water to be spouted is 2 from the above optimum temperature (42 degrees).
Assuming that a temperature as high as 44 degrees (44 degrees) is instructed, the water discharge temperature WT is changed to 44 degrees (S230). Also in this case, the LED below the numerical value 44 is turned on. After that, S1
After shifting to 30, the processing of S140 and 150 is sequentially executed. The determination in S150 in this case (determination as to whether or not another button has been newly pressed) is as follows. That is, the water button 35a, the suitable hot water button 35b,
It is determined whether any one of the hot water buttons 35c is newly pressed, and whether the appropriate hot water button 35b and the hot water button 35c are newly or simultaneously pressed.

If a negative determination is made in S220 subsequent to S200, it can be determined that the water button 35a and the hot water button 35c are simultaneously or successively pressed.
It is instructed to switch the temperature of the hot water to be spouted alternately between the water temperature and the hot water temperature, and the spout water switching cycle is set to the ROM 4
It is read from 2 (S240). This water discharge switching cycle is also stored in the ROM 42 in advance, like the amount of change in the water discharge temperature (2 degrees).

After reading the water discharge switching cycle, water or hot water is alternately discharged in the cycle (S250). That is,
The flow rate of the flow rate adjusting valve 17 is set to zero and the flow rate of the flow rate adjusting valve 15 is set to a flow rate according to the adjusted water discharge amount in each of the curran portions 31, 33, and vice versa. 0 and setting the flow rate of the flow rate adjusting valve 17 to a flow rate according to the adjusted water discharge amount in each of the currant portions 31, 33, etc.) are alternately executed in the read water discharge switching cycle. Then, the process proceeds to S150,
Determine whether it is necessary to change the water discharge, water stop, or water discharge status. The determination in S150 in this case (determination as to whether or not another button has been newly pressed) is as follows. That is, it is determined whether any one of the water button 35a, the suitable hot water button 35b, and the hot water button 35c is newly pressed, and the suitable hot water button 35b and the hot water button 35c or the suitable hot water button 35b and the water button 35a are simultaneously pressed. Alternatively, it is determined whether or not a new pressing operation has been performed one after another.

In the explanation of the above-mentioned routine, the case where each button (water button 35a, suitable hot water button 35b, hot water button 35c) of the discharge water temperature setting panel 35 is operated has been explained. Panel P
The same applies when the corresponding button of is operated.

As described above, the water discharger 1 of this embodiment
Is a water button 35a, a suitable hot water button 35b, a hot water button 35
If any one of c is pressed alone, water is discharged according to the button. That is, if the appropriate hot water button 35b is operated alone, the optimum temperature (42 degrees) for bathing or the like is designated as the temperature of hot water to be discharged, and the flow rates of water and hot water are calculated based on this temperature and the water is discharged. If either the water button 35a or the hot water button 35c is operated independently, water alone or hot water alone is discharged.

On the other hand, a suitable hot water button 35b and a water button 35a
If and are pressed at the same time or one after another, the temperature of the hot water to be spouted is lower than the optimum hot water temperature of 42 degrees (40
Degree). Then, the flow rates of water and hot water are adjusted based on the instructed lower temperature, and water is discharged. Further, with the suitable hot water button 35b and the hot water button 35c, the temperature of the hot water to be discharged is higher than the optimum hot water temperature of 42 degrees (44 ° C).
Degree) and calculate the flow rate and discharge water based on this temperature.

Further, when the water button 35a and the hot water button 35c are pressed simultaneously or successively, the temperature of the hot water to be discharged is alternately instructed at a predetermined water discharge switching cycle, Water or hot water is alternately discharged in this water discharge switching cycle.

As a result, by operating the three buttons, in addition to simple water, hot water, and hot water discharge switching, water discharge switching to hot water at a temperature lower or higher than the hot water temperature, and alternate water and hot water. It is possible to perform various kinds of water discharge switching such as water discharge switching. Therefore, according to the water discharger 1 of the present embodiment, usability can be improved by diversifying the switching of the water discharge temperature with a few button operations.

Further, in the water discharger 1 of this embodiment, button indicators 35d to 35f are provided on the left shoulders of the water button 35a, the appropriate hot water button 35b, and the hot water button 35c, and when the corresponding button is pressed. This button indicator light 35d
Since 35f is configured to be turned on, the type of water discharge including the current temperature of the water discharge can be visually recognized. Therefore, it is possible to improve the operability when switching the water discharge. Furthermore, since the temperature of the hot water being spouted is visually confirmed by turning on the LED below each numerical value in the display lamp group 35g, it is possible to improve the operability when switching the spouting.

Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment and can be implemented in various modes without departing from the scope of the present invention. Of course.

For example, the temperature of the suitable hot water (42 degrees) is set to RO beforehand.
