The present invention relates to a device for changing a set water level in a bath apparatus in which supply of water is automatically stopped.

(Prior Art) As this type of bath apparatus, for example, Japanese Patent Application Laid-Open No. 63-21442
There is one shown in Japanese Patent Publication No. In this type of bath apparatus, the set water level is usually adjusted by an adjustment volume provided inside the control device at the time of setting, and it is difficult for the user to subsequently change the set water level. there were. On the other hand, recently, a bath remote controller provided in a bathroom provided with a device for changing a set water level has been proposed.

(Problems to be Solved by the Invention) Such a set water level changing device is preferably intuitively intuitive and easy to use so that the set water level can be changed in as many stages as possible, and can be easily operated by elderly people and children. . However, such a set water level changing device is
Generally, it must be installed in a small-sized bath remote controller, so if the number of setting steps is increased, the interval between graduations will be narrow and it will be difficult to see, and if the interval between graduations is increased, the number of setting steps will be reduced, so one step However, there is a problem that the desired set water level cannot always be obtained due to a large change in the set water level at the time.

An object of the present invention is to solve such a problem.

(Means for Solving the Problems) To this end, the setting water level changing device of the bath apparatus according to the present invention is provided in the bathtub 10 or in a portion communicated therewith, as illustrated in the accompanying drawings. A water level sensor 54 for detecting the water level of the water, a switching solenoid valve 41 provided in a conduit 40 for supplying hot water or water into the bathtub 10, and the opening and closing when the water level detected by the water level sensor 54 reaches a set water level. solenoid valve
In a bath device comprising a control device 50 for closing 41,
A bath remote control device 60 for controlling the operation of the bath device via the control device 50, and a pair of operating members 61a, provided in the bath remote control device, for changing the set water level to a plurality of upper and lower stages around a reference water level, 61b, a water level display indicating the scale corresponding to the number of stages of the set water level and the scale corresponding to the changed set water level, the number being smaller than the number of stages of the set water level centered on the reference position corresponding to the reference water level provided in the bath remote control device 60 A control water level display unit A comprising
50, by operating the pair of operation members 61a and 61b in combination, changes the correspondence between the scale indicated by the water level display I and the set water level, and shifts the position indicated by the water level display I by a plurality of scales. Is the gist.

(Operation) At the beginning of the operation, the set water level is set at the position of the reference water level, and the water level display I appears at the reference position. If one of the operation members 61a is operated from this state, the set water level is sequentially changed from the reference position to each stage in the upward direction, and accordingly, the water level display I also sequentially appears at the position of the scale corresponding to the changed set water level. . By operating the other operation member 61b, the set water level is sequentially changed in each step in the downward direction, and the water level display I also appears at the position of the scale corresponding thereto. If the water level display I reaches the highest or lowest position of each scale, even if each of the operation members 61a and 61b is operated alone, neither the set water level nor the position of the water level display I will be changed earlier. .

When the two operating members 61a and 61b are operated in combination, the correspondence between the scale indicated by the water level display I and the set water level is changed, and the position of the water level display I is shifted downward or upward by a predetermined plurality of scales. Next, if each of the operation members 61a and 61b is operated alone, the set water level and the position of the water level display I are again changed to the same direction as described above.

As described above, since the water level display I is shifted downward or upward by a predetermined number of scales and then moves again, the number of scales provided in the bath remote control device 60 is smaller than the number of stages of the set water level. , Each stage of the set water level is displayed.

(Effects of the Invention) As described above, according to the present invention, all the stages of the set water level can be displayed on a scale smaller than the number of stages of the set water level, so that the set water level change width in one stage is reduced. Therefore, even if the number of setting steps is increased, the number of scales provided in the bath remote controller is reduced, and the display of the set water level becomes easy to see. Further, in the present invention, the set water level is changed stepwise by a pair of operation members and a display appears at a position corresponding to the set water level of a plurality of scales provided in the bath remote control device.
As described above, in combination with the fact that the number of scales is small, it is possible to obtain a set water level changing device of a bath device that is intuitive and easy to use.
