Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub hot water supply device equipped with a bath hot water filling display device.

[0002]

2. Description of the Related Art A bathtub hot water supply apparatus having a remote control display device for water level setting, which has been used recently, has a panel portion having a bathtub pattern in the display portion of the remote controller, and a plurality of level display elements are provided in the horizontal portion of the bathtub pattern. By adopting a lighting display method in which the bathtub water level setting display position is moved up and down by pressing the water level setting key and the setting is changed, the display element is lighted accordingly. In this case, the number of water level setting keys attached to the display section of the remote controller is one in order to simplify the key operation and the number of keys for the entire remote controller. That is, the water level is set by operating only a single water level setting key.

[0003]

However, the conventional bathtub water level setting display of the remote control is a display method in which the display element that has been displayed until now disappears at the moment when the water level setting key is pressed. There was a drawback that it was difficult to determine the relative relationship with the water level.

In view of the above situation, the present invention provides a bathtub hot water supply apparatus which solves the above problems by causing a plurality of display elements for displaying the bathtub water level setting to perform at least an identification lighting for lighting the initial water level and the current water level. It is intended to be provided.

[0005]

According to the present invention, there is provided a water level detecting means for detecting the water level of a bathtub, a water level setting means for setting the water level of the bathtub, and a plurality of displays corresponding to the water level set by the water level setting means. An element, and a control device for controlling the hot water supply to the bathtub by comparing the detected water level of the water level setting means and the set water level of the water level setting means, and for displaying the set water level of the water level setting means on the plurality of display elements. When the water level setting means is operated, the control device displays the set water level before the setting operation and the set water level after the setting operation on the plurality of display elements in different lighting states.

Further, water level detecting means for detecting the water level of the bathtub, water level setting means for setting the water level of the bathtub, a plurality of display elements corresponding to the water level set by the water level setting means, and detection of the water level setting means The water level and the set water level of the water level setting means are compared to control hot water supply to the bathtub, and a control device for displaying the set water level of the water level setting means on the plurality of display elements is provided. When the operation is performed, the set water level after the setting operation is lit and displayed on the plurality of display elements, and the set water level before the setting operation is blinked on the plurality of display elements for a predetermined time.

[0007]

With the above-mentioned structure, when the water level of the bathtub is automatically set when the water level is set by pressing the water level setting key, which serves as the water level setting means of the remote controller, the display element of the lamp structure is turned on. The initial water level setting can be known by turning on the display element of the preset water level and turning on the display element by the water level setting key that has just been pressed.

In this case, when a new display element lights up in response to the operation of the water level setting key (current water level setting), the lighting of the display element which has been set up to now is switched to blinking lighting.
In addition, at this time, if the key pressing operation of the water level setting key is continuously performed a plurality of times within the predetermined time, the blinking of the first display element is kept as it is and the lighting is shifted to another display element for the number of times of pressing, It makes it easier to distinguish the correlation with the current water level.

On the other hand, for the bathtub, the detected water level of the water level detecting means and the set water level of the water level setting means are compared to control hot water supply to perform desired filling of water.

The present invention will be described below with reference to the drawings of the embodiments.

FIG. 1 and FIG. 2 show a bath water heater having a bath water filling function, and 1 is a remote controller of a water heater (not shown) having a bath water filling function.
A bathtub pattern 2 is displayed on the display portion of the operation panel 1a of the remote controller 1.
And a plurality of display elements 3 for indicating the water level are arranged in the vertical direction on its side, and a clock display unit 4, an additional heating display unit 5, a bath temperature display unit 6, and a hot water temperature display unit are provided. 7
Etc. are provided, and a water level setting key 8 serving as a water level setting means is provided near the bathtub pattern 2 on the operation unit, and a time adjustment key 9, an automatic operation switch 10 and a bath temperature serving as an up / down key are provided. A key 11, a hot water supply temperature key 12, a switch 13 for exclusive use of reheating, and the like are arranged. Further, the microcomputer 14 serving as a control device has the water level setting key 8 on the input side.
An automatic operation switch 10, a bath temperature key 11, a hot water supply temperature key 12, an operation part of a dedicated heating switch 13, a hot water supply temperature sensor 15, a water flow switch 16 and a bath pouring counter 1

With these configurations, the bathtub water heater is provided.

Next, the bathtub water level setting will be described with reference to the flow chart shown in FIG. 3. First, when the water level setting key 8 is pressed as bathtub water level setting processing, the automatic bath operation is turned on in advance.
, The microcomputer 14 determines whether there is a water level setting input. The first water level setting key operation requires input (because it is assumed that the previous water level setting was made), and since the 10-second timer is not working, the current water level setting value is the current water level setting. It is stored in the memory (initial water level setting). Then 10
The timer starts operating when the second timer is set. At this time, since there is no water level UP flag at first, it proceeds to the right and determines whether the current water level setting is MIN (whether it is at the lowest position). For example, if the lighting position of the display element for initial water level setting is not the lowest, it is not MIN, so the currently set water level is 1
The rank becomes smaller, and the display element corresponding to the initial water level setting starts blinking and the display element corresponding to the currently set water level becomes lit (see FIG. 4).

Next, when the first water level setting key operation is performed (10 seconds has elapsed), the display element corresponding to the initial water level setting, which is the display element for the initial water level setting, is turned off and the water level UP flag is reset. Only the display element corresponding to the current set water level lights up.

After the first operation of the water level setting key, 1
If the second key operation is performed within 0 seconds, the display element corresponding to the initial water level setting remains blinking, the display element that is turned on by the first water level setting key operation is turned off, and the display element at the position below it is turned off. It will be turned on. Of course, the current water level setting will be one rank lower.

When the water level setting key is further operated and the currently set water level is the minimum value (MIN), the water level UP flag is set and the currently set water level is increased by one rank, and the water level is increased by one of the lowest display elements. Lights up. Then, when the operation of the water level setting key 8 is further repeated, the currently set water level is increased by one rank, and the lighting of the display element is moved up one by one. Of course, when the currently set water level is MAX, the water level UP flag is reset, and thereafter, the currently set water level decreases by one rank, and the lighting of the display element shifts downward. At the time when 10 seconds have passed since the last key operation was stopped, the initial water level setting display element is turned off and the water level UP flag is also reset. This means that there is no water level UP flag at the first key operation.

Here, as pouring into the bathtub 26,
As shown in FIG. 5, the hot water flowing out of the hot water supply heat exchanger 27 heated by the ignition of the gas burner 21 flows into the bathtub 26 through the bath pouring counter 17. The water level accumulated in the bathtub 26 is detected by a water level detecting means 25 serving as a water pressure sensor, and a predetermined amount of molten metal is poured under the control of the microcomputer 14.

[0017]

As described above, the bath water heater of the present invention uses a remote controller or the like to display the water level using a plurality of display elements, and it is possible to set the original water level (initial water level) and the current water level. The display element for the current water level is turned on, and the display element for the one (the original water level setting display element) is switched to blinking, and the display element for the current water level setting is turned on to determine the correlation between the current water level and the original water level. To ensure. Further, when the water level setting is sequentially changed within a predetermined time (within 10 seconds of one key operation), the display element corresponding to the currently set water level is turned on for each operation while the original display element is kept blinking.
That is, it becomes clear how many steps the current setting position is changed. Further, after a predetermined time has elapsed (after confirmation) of the setting operation, the original blinking display is extinguished, so that useless display is eliminated.
