DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water discharge device for adjusting a water discharge temperature from a water discharge port at a specified temperature, and an operation panel attached to the water discharge device.

[0002]

2. Description of the Related Art A water discharge device of this kind is disclosed in
As shown in No. 26, there is provided an operation panel for setting the water discharge temperature by button operation, and a temperature adjustment mechanism (water tap) for actually adjusting the water discharge temperature based on the button operation on this panel. Then, the setting and change of the water discharge temperature are realized by a simple operation of pressing a button.

[0003]

Generally, since the water discharge device is used in a bathroom, a sink, or the like, the water discharge temperature is frequently changed according to the state of use. In this case, it is not always possible to perform the pressing operation while visually confirming the buttons for setting the temperature (the “warm button” and the “hot button” in the above-mentioned public information). For example, when the face is being washed or the hair is being washed, the user may perform the pressing operation by fumbling with the help of memorizing the approximate arrangement of the buttons on the operation panel.

In such a case, for example, in order to lower the water discharge temperature, it is intended to press the warm button, but the two buttons may be pressed simultaneously or successively. In order to avoid such erroneous operation of the button by the user's intention, it is necessary to constantly pay attention to ensure that the finger touches the button intended to be pressed, which is troublesome.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a water discharging device which can easily avoid an erroneous operation when performing a water discharging temperature changing operation.

[0006]

In order to achieve the above object, a means adopted by the present invention is to provide a water discharge temperature adjusting means for adjusting a water discharge temperature from a water discharge port when a predetermined operation is performed. A water discharge device comprising: a water discharge temperature increase instruction operation unit for instructing a rise, and a water discharge temperature decrease instruction operation unit for instructing the water discharge temperature adjustment unit to lower the water discharge temperature when a predetermined operation is performed, wherein The gist of the present invention is to provide an instruction invalidating means for invalidating a water discharge temperature change instruction from both the instruction operation units when the water discharge temperature increase instruction operation unit and the water discharge temperature decrease instruction operation unit are operated. .

In addition, the following means are employed. As one of them, in providing the water discharge temperature increase instruction operation unit and the water discharge temperature decrease instruction operation unit on the operation panel, the water discharge temperature increase instruction operation unit and the water discharge temperature decrease instruction operation unit are separated from each other by at least the width of the finger of the person. It was decided to provide.

In addition, the operation panel is provided with a temperature display means in addition to the water discharge temperature increase instruction operation unit and the water discharge temperature decrease instruction operation unit, and the temperature display means is provided with the water discharge temperature increase instruction operation unit and the water discharge temperature decrease instruction operation unit. And arranged between them.

Further, a temperature display means provided between the water discharge temperature increase instruction operation unit and the water discharge temperature decrease instruction operation unit and provided on the operation panel is provided from the water discharge temperature decrease instruction operation unit to the water discharge temperature increase instruction operation unit. A display device group that individually displays the detected water discharge temperatures in ascending order.

[0010]

In the water discharge device having the above structure, when the water discharge temperature increase instruction operation unit or the water discharge temperature decrease instruction operation unit is operated, the water discharge temperature adjusting means is instructed to increase or decrease the water discharge temperature, and the instruction is received. The water discharge temperature is adjusted by adjusting the water discharge temperature from the water discharge port by the water discharge temperature adjusting means.

When the water discharge temperature increase instruction operation unit and the water discharge temperature decrease instruction operation unit are operated within a predetermined time, the instruction disabling means invalidates the water discharge temperature change instruction from both instruction operation units. Therefore, even if an erroneous operation of operating either one of the instruction operation units simultaneously or one after another is performed to operate one of the instruction operation units, the water discharge temperature is not changed. Therefore, such erroneous operation can be avoided even when the two instruction operation units remain close to each other.

[0012] In providing the two instruction operation sections on the operation panel, the water discharge device having an interval at least as large as the width of a human finger prevents such erroneous operation by providing such an interval between the two instruction operation sections. Make it possible.

Further, in the water discharge device having the temperature display means provided on the operation panel in addition to the two instruction operation parts, the temperature display means is disposed between the water discharge temperature increase instruction operation part and the water discharge temperature decrease instruction operation part. With this arrangement, it is possible to avoid the erroneous operation by increasing the interval between the two instruction operation units.

Further, the water discharge device in which the temperature display means between the two instruction operation sections is constituted by a group of display devices is provided. Are individually displayed in ascending order, so that the water discharge temperature decrease instruction operation unit is disposed on the side where the water discharge temperature is low and the water discharge temperature increase instruction operation unit is disposed on the side where the water discharge temperature is high. As a result, the interval between the two instruction operation units is further increased, and the erroneous operation is reliably avoided. In addition, it is possible to avoid other erroneous operations (inadvertently pressing the other instruction operation unit while groping around it in an attempt to operate one instruction operation unit).

The water discharge temperature setting panel 37 of the Baskaran BK has the same configuration. Further, the operation panel P is also provided with these buttons and indicator lights.

Next, the water discharge control (routine) and the water discharge temperature change control (routine) performed by the water discharge device 1 of the present embodiment having the above-described configuration will be described with reference to the flowcharts of FIGS. When using the water button, the hot water button, the hot water button, or the like in describing the routine, for convenience of description, the buttons (water button 35) on the water discharge temperature setting panel 35 of the washing area Kallang AK are used.
a, the appropriate hot water button 35b, and the hot water button 35c) will be described.

The water discharge routine shown in FIG. 4 is repeatedly executed from the time when the power is turned on. First, an initial process to be executed only when the power is turned on, that is, the internal register of the CPU is cleared. Then, as shown in FIG.
The water button 35a and the appropriate hot water button 3 on the water discharge temperature setting panel 35
5b, it is determined whether or not the appropriate hot water button 35b of the hot water button 35c is pressed (Step 110: hereinafter, the steps are simply referred to as S).

Here, if it is determined that the pressed button is the appropriate hot water button 35b, it is assumed that an optimum temperature for bathing or showering, for example, 42 degrees, is designated as the temperature of hot water to be discharged, and that temperature is determined. Is read from the ROM 42 as data used for flow rate calculation described later (S120). The optimum temperature (water discharge temperature) is set and stored in advance in the ROM 42 as a suitable hot water temperature. When the above determination is made, the control signal is output from the electronic control unit SS to the water discharge temperature setting panel 35, and the LED of the numerical value 42 in the indicator light group 35g is turned on. Water discharge temperature setting panel 3
7 is the same.

Thereafter, the water discharge temperature change amount TW0 written in a predetermined address of the RAM 43 is read in a water discharge temperature change routine described later, and the water discharge temperature change amount TW0 is added to the appropriate hot water temperature to determine the water discharge temperature TW. (S12
5). The flow rates of water and hot water are calculated based on the water discharge temperature TW (S130). Since the initial value zero is set to the water discharge temperature change amount TW0 when the power is turned on, the appropriate hot water button 35
If the water discharge temperature is not changed by the temperature increase instruction button 35i or the like after the operation of b, the appropriate hot water temperature (42 degrees) read in S120 becomes the water discharge temperature TW. The water discharge temperature change amount TW0 is a positive or negative number. If the value is positive, the water discharge temperature TW increases, and if the value is negative, the water discharge temperature TW decreases.

Then, the flow control amounts of the flow control valves 15 and 17 corresponding to the calculated flow rates, that is, the drive amounts of the actuators 19 and 21 are obtained, and a drive signal is output to each actuator (S14).
0). In response to this signal, each actuator is driven and each flow rate adjustment valve adjusts the flow rate, so that the calculated flow rate of water and hot water flows into the merging flow path 23 and from the water discharge destination switched and controlled by the water discharge switching section 27. If there is no change in the water discharge temperature, a suitable hot water having a suitable hot water temperature (42 degrees) is discharged as the water discharge temperature. Further, when the water discharge temperature is changed as will be described later, the water having the water discharge temperature TW determined from the appropriate hot water temperature and the water discharge temperature change amount TW0 is discharged. In calculating the flow rates of water and hot water (actuator drive amount), the water discharge temperature T
In addition to W, the temperature and flow rate of the water itself and the temperature and flow rate of the hot water in the inflow pipes 3 and 5 from the flow rate sensors 7 and 9 and the temperature sensors 11 and 13, and the temperature sensor 25 provided in the merging flow path 23. Water temperature detected from the water, each curan part 31,3
3 or the adjusted water discharge amount in the shower head S is considered.

The water discharge destination determined by the water discharge switching unit 27 is the water discharge temperature setting panel 3 if the pressed hot water button is a button of the water discharge temperature setting panel 35.
If the button is 7, it becomes the Baskaran BK. Further, the operation is switched to the shower head S in addition to each of these curls by operating a water discharge destination selection button (not shown) on the operation panel P. Further, the switching control of the water discharge destination is performed when the appropriate hot water button on 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 thus discharged, each of the curan parts 3
It is determined whether the water discharge amount has been set to zero in the shower head 1, 33 or the shower head S, that is, whether the water has been stopped, or whether other buttons (in this case, the water button 35a and the hot water button 35c) have been newly pressed. A determination is made (S150). Here, if a negative determination is made, the water discharge state up to now is continued, and the processing from S130 on is repeated. If an affirmative determination is made, the current water discharge state is stopped or changed to another water discharge state. The process ends.

On the other hand, if a negative determination is made in S110 described above, it can be determined that either the water button 35a or the hot water button 35c other than the appropriate hot water button 35b has been pressed alone. Therefore, in this case, a drive signal is output to each actuator of each flow control valve as follows (S16).
0), adjust the flow rate and discharge water.

The button pressed alone is the water button 3
If it is determined that the temperature is 5a, it is determined that the temperature of water is instructed as the water discharge temperature, and each flow rate adjustment valve is driven via each actuator. That is, the flow rate of the flow control valve 17 in the inflow pipe 5 on the hot water side is zero, and the flow rate of the flow control valve 15 in the inflow pipe 3 on the water side is equal to each of the curran portions 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. In response to 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 flow path 23 and is discharged. When it is determined that the button pressed alone is the hot water button 35c, it is determined that the temperature of the hot water has been instructed as the water discharge temperature, and the respective flow control valves are driven via the respective actuators. That is, a drive signal is output to each actuator in which the flow rate of the flow rate adjustment valve 15 is zero and the flow rate of the flow rate adjustment valve 17 is a flow rate corresponding to the adjusted water discharge amount in each of the curran sections. In response to this signal, each actuator is driven and each flow rate adjusting valve adjusts the flow rate, so that only hot water flows into the merging flow path 23 and is discharged.

Thereafter, the flow shifts to S150, performs the above-described processing, and terminates the present routine. In this case, the determination in S150 (determination of whether or not another button has been newly pressed) is as follows. That is, when the water button 35a is operated alone, it is determined whether the hot water button 35c or the appropriate hot water button 35b is newly pressed as another button, and when the water button 35c is operated alone,
It is determined whether the water button 35a or the appropriate hot water button 35b has been newly pressed as another button.

Next, the water discharge temperature change control (routine) will be described with reference to the flowchart of FIG. The water discharge temperature change routine of FIG. 5 is executed when the temperature decrease instruction button 35h or the temperature increase instruction button 35i is operated. First, the normal operation for changing the water discharge temperature TW is performed when the temperature decrease is performed. It is determined whether the instruction button 35h or the temperature increase instruction button 35i is solely operated, or whether an erroneous operation has been performed such that the two instruction buttons are simultaneously or successively pressed in a short time (for example, 0.5 seconds). A determination is made (S200).

Here, at S200, the temperature lowering instruction button 3
If it is determined that either 5h or the temperature increase instruction button 35i has been pressed alone, it is determined that the normal operation has been performed, and the following water discharge temperature changing process is performed to change the water discharge temperature TW (S210 to S230).

First, the change amount ΔT of the water discharge temperature desired by the user is determined based on the number of operations and the operation frequency of the temperature lowering instruction button 35h (S210). For example, if the temperature lowering instruction button 35h is operated alone twice in succession, the user determines that the user wants the water discharge temperature one degree lower than the current water discharge temperature TW, and determines ΔT = −1 degree. The degree of change in the water discharge temperature is stored in the ROM 42 in advance in association with the number of times of operation of the instruction button, the operation frequency, and the like. Next, the water discharge temperature change amount TW0 up to the previous time written in the predetermined address of the RAM 43 is read (S22).
0). Thereafter, the desired temperature change amount ΔT (= −1) is added to the previous water discharge temperature change amount TW0 to update the same, and the updated water discharge temperature change amount TW0 is written to the above address of the RAM 43 (S230). End the routine. For example, if the previous water discharge temperature change amount TW0 is 2 degrees, the updated water discharge temperature change amount TW0 is 1 degree (= 2-1).

When the water discharge temperature change amount TW0 is updated and written in this way, the water discharge temperature TW is changed by adding the updated water discharge temperature change amount TW0 to the appropriate hot water temperature (42 degrees) at S125 in the water discharge routine. Thereafter, in S130, the flow rates of water and hot water are calculated based on the changed water discharge temperature TW. As a result, water is discharged from the water discharge destination of each of the callan units at the changed water discharge temperature TW. Water discharge temperature change amount TW after update
If 0 is 1 degree as described above, 44 degrees before the water discharge temperature change processing (the previous water discharge temperature change amount T becomes 42 degrees of the appropriate hot water temperature).
(The temperature obtained by adding two degrees of W0) to 43
Degree (the discharged water temperature change amount TW0 after updating to the appropriate hot water temperature of 42 degrees)
(The temperature obtained by adding 1 degree of

When the water discharge temperature TW is changed as described above, a control signal corresponding to the changed water discharge temperature TW is output from the electronic control unit SS to each water discharge temperature setting panel, and the numerical value of the indicator lamp group is changed. LED is turned on. For example, if the water discharge temperature TW after the change is 41 degrees as described above, the control signal is output to the LED of numerical value 40 and the LED of numerical value 42, and both LEDs are turned on.

On the other hand, in S200, the temperature lowering instruction button 35
h, when it is determined that both of the temperature increase instruction buttons 35i are pressed simultaneously or successively, the routine is terminated without performing the water discharge temperature change process assuming that the erroneous operation has been performed. Therefore, since the water discharge temperature change amount TW0 is maintained at the previous value, the water discharge temperature TW is not changed in S125 in the water discharge routine, and water is discharged at the water discharge temperature TW.

In the description of each routine described above, each button (water button 35) on the water discharge temperature setting panel 35 will be described.
a, the appropriate hot water button 35b and the hot water button 35c) have been described, but the same applies to the case where each button of the water discharge temperature setting panel 37 or the operation panel P is operated.

As described above, the water discharge device 1 of the present embodiment
If the normal operation of pressing either the temperature decrease instruction button 35h or the temperature increase instruction button 35i for changing the water discharge temperature TW is performed alone, the water discharge temperature T
W is changed and water is discharged at the changed water discharge temperature TW. On the other hand, if an erroneous operation is performed such that the two instruction buttons are pressed simultaneously or successively, this operation is invalidated and the water discharge temperature TW is not changed. As a result, according to the water discharge device 1 of the present embodiment, even if there is an erroneous operation in the operation of changing the water discharge temperature, such an erroneous operation can be easily avoided by invalidating such an operation. In addition, even with a conventional water discharging device in which both instruction buttons are arranged close to each other, the conventional water discharging device can be made a device capable of avoiding erroneous operation by a simple improvement of adding the above-described processing. .

In the water discharging apparatus 1 of this embodiment, the button indicators 35d to 35f are provided on the left shoulder of each 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 turned on, the type of water discharge including the current temperature of water discharge can be visually recognized. Therefore, the operability at the time of the water discharge switching can be improved. Further, since the temperature of the discharged water is visually recognized by turning on the LED of each numerical value in the indicator light group 35g, the operability at the time of the water discharge switching can also be improved.

Next, a modified example of the water discharge device 1 of the above embodiment will be described with reference to FIGS. In the modified examples described below, as shown in the drawing, a button arrangement on a water discharge temperature setting panel and a display device for displaying temperature are different.

The water discharge temperature setting panel 35 of the modification shown in FIG.
Has a temperature decrease instruction button 35h and a temperature increase instruction button 35i for changing the water discharge temperature TW, which are provided below the numerical values (38, 46) at both ends of the indicator light group 35g. The water discharge temperature setting panel 35 of the modification shown in FIG.
Temperature decrease instruction button 35h and temperature increase instruction button 35i
Are disposed outside the numerical values (38, 46) at both ends of the indicator light group 35g. Further, the water discharge temperature setting panel 35 of the modified example shown in FIG.
Instead of g, a display device 35k that directly displays a numerical value of the temperature is used, and each instruction button is arranged and provided outside the display device 35k.

Even in the water discharge device 1 using each of the water discharge temperature setting panels 35 in the modified example, the erroneous operation at the time of changing the water discharge temperature is invalidated by each process in the above-described water discharge temperature change routine, and the erroneous operation is easily avoided. can do.

Further, in each of the water discharge temperature setting panels 35 in the modified example, a temperature lowering instruction button 35h and a temperature lowering button 35h are provided below or outside the numerical values at both ends of the display lamp group 35g or outside the display device 35k. Increase instruction button 3
5i are arranged and provided, so that these two instruction buttons are separated from each other by the width of the finger N of the person as shown in FIG. As a result, according to the water discharge device 1 having the water discharge temperature setting panel 35, the following erroneous operation can be avoided.

In order to change the water discharge temperature, for example, when pressing the temperature lowering instruction button 35h to lower the water discharge temperature, the user operates the button with a rough indication of the approximate position of the button on the panel. There is. In such a case, it is easy to accidentally press the other instruction button while groping around the button. However, such an erroneous operation can be avoided in each of the water discharge temperature setting panels 35 of the modified example in which each of the instruction buttons is separated by more than the width of the finger N of the person. Therefore, in the water discharge device 1 using each water discharge temperature setting panel 35 in the modified example, the process of S200 in the water discharge temperature changing routine described above (determination of whether or not both instruction buttons are pressed simultaneously or successively) is omitted. May be.

The embodiment of the present invention has been described above.
The present invention is not limited to such embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.

For example, the temperature (42 ° C.)
Although the configuration is such that the optimum hot water temperature is stored in the control panel M provided in the shower tower ST, the changed hot water temperature can be changed by the electronic control unit SS.
May be configured to be stored in the backup RAM 44. In this case, the appropriate hot water temperature is set and stored for each user of the water discharging device 1, and the set appropriate hot water temperature is operated by a predetermined button operation (for example, an operation of a suitable hot water temperature selection button provided on the operation panel P). By using, water can be spouted at a temperature suitable for the user's preference. Further, the degree of change of the water discharge temperature can be changed on the operation panel P in the same manner as the suitable hot water temperature, and the change can be stored in the backup RAM 44. Also in this case, the water discharge temperature can be changed according to the user's preference.

[0051]

As described in detail above, the water discharge device of the present invention is capable of erroneously operating such an operation when the respective operation sections for changing the water discharge temperature to be lower and higher are operated simultaneously or successively by mistake. As invalid and do not change the water discharge temperature.
As a result, according to the water discharge device of the present invention, such an erroneous operation can be easily avoided.

Further, when providing each operation section for changing the water discharge temperature to a relatively high and low level on the operation panel, the interval between the operation sections should be at least equal to or greater than the width of a human finger, and temperature display means should be provided between both operation sections. Thus, the two operation units are separated from each other so that the erroneous operation can be easily avoided. Further, by using a display device group that individually displays the detected water discharge temperatures in ascending order from the operation unit that lowers the water discharge temperature to the operation unit that raises the water discharge temperature, the interval between both operation units is further increased. As a result, not only an erroneous operation that both operation units are operated simultaneously or one after another, but also an erroneous operation that the other operation unit is erroneously operated while groping around to try to operate one operation unit Can also be easily avoided.
