DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water discharge device capable of changing a water discharge amount.

[0002]

2. Description of the Related Art A water discharge device of this kind is disclosed in
As shown in No. 26, the operation panel is provided with a "less button" and a "many button" for adjusting the amount of water discharge, and presses each of these buttons to change the amount of water discharge to a smaller or larger amount.

[0003]

If the amount of water discharge can be changed in this way, there is a demand to visually recognize the changed amount of water discharge on a display device. It should be noted that the water discharge amount is generally displayed as a graph because it does not give a real feeling even when a numerical value such as 2 liters or 30 liters is displayed as in the display of the water discharge temperature.

[0004] In order to respond to the request for visualizing the amount of water discharged through the graph display of the amount of water discharged, a display device for displaying the amount of water discharged graphically may be provided on the operation panel. By the way, for example, a bathroom is provided with a plurality of water outlets such as a shower, a bath currant, and a wash basin, and a changeable water discharge amount range is different for each water spout.

Accordingly, a display device for the water discharge amount may be provided on the operation panel for each water outlet, and the display range of the graph display on each display device may be adjusted to the corresponding water outlet, but the operation panel is correspondingly large. However, it is not preferable because the installation position is restricted. In addition, since the target of water discharge is a single water outlet in many cases, only the display device corresponding to the water discharge target which is the target of water discharge is actually used to display the water discharge amount. The water mouth display device will not be used.

Therefore, by using a display device having a wide display range of the graph display, it is possible to realize a downsized operation panel and a graph display of the amount of water discharged from all the water outlets. However, when the water outlet whose changeable water discharge amount range is a small amount range is a water discharge target, the graph display of the water discharge amount from this water discharge port becomes small, making it difficult to see, and the visibility is reduced. Further, when the water discharge amount is changed, it is difficult to determine how the water discharge amount changes.

[0007] In recent years, shower water spouting has been changed to a water spouting form (straight), for example, a water spouting form (straight) for spouting water in a straight form, and a water spouting form (foam) for spouting water in a foam form by including bubbles. There have been proposed ones that can be appropriately changed from a water discharge form (supply) in which water is discharged in a rod shape with a certain head or a water discharge form (mist) in which water is discharged in a mist form. As described above, even when the water discharge mode can be changed, there is a request to visually check the water discharge amount on a display device, as in the case of the water discharge port, and a similar problem is pointed out.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to improve the visibility of a water discharge amount display with a small number of display devices.

[0009]

Means for Solving the Problems A first means adopted by the present invention for achieving the above object is a water discharge device having a plurality of water discharge ports capable of changing a water discharge amount, wherein A storage means for storing a reference water discharge amount, a water discharge port determining means for determining a water discharge target to be discharged, and a water discharge amount discharged from the determined water discharge target water discharge port, wherein the determined water discharge target water discharge port is The gist of the invention is to provide a display means for displaying a graph as a relative water discharge amount relative to the reference water discharge amount stored in the storage means.

[0010] A second means employed is a water discharging apparatus having a water discharging port capable of changing a water discharging mode and changing a water discharging amount for each water discharging mode, wherein the water discharging mode of the water discharging port is changed. A storage means for storing a reference water discharge amount, a water discharge form determining means for determining a discharged water discharge form, and a water discharge amount discharged in the determined water discharge form, and the storage means for the determined water discharge form. The gist of the present invention is to provide a display means for displaying a graph as a relative water discharge amount relative to the stored reference water discharge amount.

[0011]

According to the water discharge device having the above configuration, when the amount of water discharged from the water discharge target water outlet determined as the water discharge target by the water discharge port determination means is graphically displayed on the display means, the standard stored in the storage means with respect to the water discharge target water discharge port is used. As a relative water discharge amount with respect to the water discharge amount, the water discharge amount from the water discharge target water discharge port is graphically displayed.

Therefore, even if the range of water discharge amount that can be changed at each water outlet is different for each water outlet, the water discharge amount from each water outlet can be graphically displayed in the same display range through the relative display with the reference water discharge amount. Becomes possible.

[0013] On the other hand, the water discharge device according to the second means, when the water discharge amount in the water discharge form determined by the water discharge form determination means is graphically displayed by the display means, the reference discharge means stored in the storage means with respect to the determined water discharge form. The water discharge amount in the determined water discharge form is displayed as a graph as the relative water discharge amount with respect to the water amount.

Therefore, even if the range of water discharge amount that can be changed in each water discharge mode is different for each water discharge mode, the water discharge amount in each water discharge mode is displayed in a graph in the same display range through the relative display with the reference water discharge amount. It becomes possible.

[0015]

In order for the water discharged in the water discharge form determined by this water discharge form map to be discharged from the shower head S, the code corresponding to the shower head S in the water discharge destination map is set to the value 1.
Is done when is written. The writing of the code of the value 1 into the water discharge form map can be performed by using the singing designation button 57 and the straight designation button 5 on the operation panel P.
8. When the foam designation button 59, the mist designation button 60, or the water discharge mode selection button 84 of the shower head S is pressed, an interruption process is performed. Also, in the initial processing, a code of value 1 (water discharge mode selection) is written only for a straight water discharge mode that is frequently used.

Next, the reference water discharge amount relating to the water discharge port or water discharge form determined in S110 is stored in the backup RAM 44.
(S120), the read reference water discharge amount is
The display is performed by continuously lighting only the display segment 52d of the water discharge amount display 52 (S130). For example, S
If it is determined in step 110 that the water discharge destination is the shower head S and that the water discharge mode is the squatting water discharge mode, the process proceeds to step S12.
The reference water discharge amount (10 liters / minute) relating to the water discharge mode of singing at 0 is read from the backup RAM 44,
Only the display segment 52d of the water discharge amount indicator 52 is displayed continuously. When it is determined that the water discharge mode is straight, 12 liters / minute is read as the reference water discharge amount. Only 52d is displayed continuously. That is, regardless of the water outlet and the water discharge mode, the water discharge amount display 52
Only the display segment 52d is displayed continuously.

Thereafter, the set water discharge amount Q0 relating to the water discharge port or water discharge form determined in S110 is set to the backup RA.
It is read from M44 (S140), and the set water discharge amount Q0 read in S140 is converted into a relative water discharge amount with respect to the reference water discharge amount read in S120 (S150). For example, if it is determined in step S110 that the mode is the squatting water discharge mode, the set water discharge amount Q0 relating to the squatting water discharge mode is read in S140 and converted into a relative water discharge amount.

The set water discharge amount Q0 is determined by the water discharge lowering instruction button 35h and the water discharge increase instruction button 35i on the water discharge setting panel 35 of each curan, and the water discharge amount increase instruction button 64 and the water discharge amount lower instruction button 65 on the operation panel P. The data is updated and written to a predetermined address in the backup RAM 44 each time a manual operation is performed. In addition, this writing
Interruption processing is performed when the corresponding button is operated, and the setting is made according to each water outlet and water discharge mode.

Next, the converted relative water discharge amount is displayed by blinking the display segments 52a to 52g in the water discharge amount display 52 in combination (S16).
0), the processing of this routine is temporarily ended. For example, S1
In step 10, the form of spouting water is determined, and if the set water discharge amount Q0 read in S140 is 14 liters / minute, it is displayed as follows.

In step S130, the reference water discharge amount (10 liters / minute) relating to the form of water discharge is displayed by turning on only the display segment 52d of the water discharge amount display 52. Therefore, the set water discharge amount Q0 for this reference water discharge amount is displayed. The relative water discharge amount of 14 liters / minute is displayed by blinking all the display segments 52a to 52f.

In step S110, the form of water discharge of the foam is determined. If the set water discharge amount Q0 read in step S140 is 14 liters / minute, the reference water discharge amount for the form of water discharge of foam is 8 liters / minute. The relative water discharge amount of the set water discharge amount Q0 (14 liters / minute) with respect to the reference water discharge amount is displayed by blinking all display segments 52a to 52g.

On the other hand, if the set water discharge amount Q0 matches the reference water discharge amount, all the display segments 52a to 52d are displayed by blinking, and this blinking display is performed to display the reference water discharge amount. Display segment 52d
Give priority to lighting only. That is, when the set water discharge amount Q0 matches the reference water discharge amount, lighting of only the display segment 52d is interrupted.

As described above, the water discharge device 1 of the present embodiment
Determines the water discharge form at the time of the water discharge port or the shower water discharge set as the water discharge destination, and when displaying the graph of the water discharge amount from the determined water discharge port or the water discharge amount in the determined water discharge form, the water discharge port or A graph is displayed as a relative water discharge amount relative to the reference water discharge amount for the water discharge mode.

As a result, according to the water discharge device 1 of the present embodiment, regardless of the water discharge port or the water discharge form in which the changeable water discharge amount range is different, each water discharge port or water discharge form can be displayed relative to the reference water discharge amount. The amount of water discharged in the water discharge mode can be graphically displayed in the same display range, and the visibility can be improved. Moreover, while using only one display device,
The water discharge amount can be displayed for all water discharge ports and water discharge forms with good visibility. Therefore, it is possible to reduce the size of the operation panel P by saving the installation area of the display device.

Further, when the set water discharge amount Q0 in the determined water discharge port or water discharge form matches the reference water discharge amount, all the display segments 52a to 52d blink regardless of the water discharge form or water discharge form. In this case, the common recognition is performed when the set water discharge amount Q0 is equal to the reference water discharge amount, and the visibility can be improved.

Further, since the display of the set water discharge amount Q0 and the display of the reference water discharge amount as the relative water discharge amount relative to the reference water discharge amount are simultaneously performed, the comparison between the reference water discharge amount and the set water discharge amount Q0 can be determined at a glance. Moreover, the display of the set water discharge amount Q0 as a relative water discharge amount relative to the reference water discharge amount is made to blink, and the display of the reference water discharge amount is made to be continuously lit, so that the reference water discharge amount and the set water discharge amount Q0 can be more reliably compared. can do.

In addition, the water discharge amount of each water discharge port and water discharge form can be selected from seven levels of water discharge amount, and the water discharge amount display 52 can be configured from seven display segments to change the water discharge amount. The number of stages (seven levels) and the number of display segments on the water discharge amount display 52 were made to match. Therefore, control for displaying the set water discharge amount Q0 as a relative water discharge amount with respect to the reference water discharge amount can be simplified.

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

For example, in the above-described embodiment, in addition to the shower head S that can change the water discharge mode and the water discharge amount can be changed for each water discharge mode, the water discharge device provided with the wash area Karan AK and the bath curan BK that can change the water discharge amount. However, it is needless to say that a water spouting device provided with only the shower head S or a water spouting device provided with the washing place Karan AK and the bath Karan BK may be used.

Further, in the water discharge device 1 of this embodiment, the reference water discharge amount is a fixed value for each water discharge port and each water discharge mode. However, this reference water discharge amount is set for each water discharge port or each water discharge form. It can be configured to be changeable within the range.

In addition, when displaying the water discharge amount in each water discharge port or each water discharge mode, a water discharge lowering instruction button 3
Although the set water discharge amount Q0, which is set as the water discharge amount for 5 hours or the like, is displayed, the flow amount passing through the merging flow path 23 can be detected and used as the water discharge amount to be displayed.

Further, it has been described that the water discharge amount which can be changed can be selected from seven water discharge amounts for each water discharge port and water discharge form. However, the water discharge amount is not limited to seven steps and can be continuously changed. Further, although the water discharge amount indicator 52 is constituted by seven display segments, it may be constituted by, for example, five display segments. Alternatively, the number of stages (seven levels) in which the water discharge amount can be changed and the number of display segments of the water discharge amount display 52 are made to match, but it is a matter of course that they may be different.
