Detection means is provided, and control means for controlling the adjusting means based on the detection information of the detection means is provided so that the hot water state becomes the set target hot water state in response to the start command. The present invention relates to a bathtub hot-watering device provided with a notifying means for notifying that the control of the adjusting means by the control means has been completed as a set target hot-water state has been reached.

[Conventional technology]

In the bathtub hot water device as described above, for example, the control means is started by operating a hot water switch, etc., and automatically adjusts the hot water state to the set target hot water state, that is, Heating of bathtub water or hot water supply to the bathtub is performed.

Conventionally, each time the control means is activated and the hot water state reaches the set target hot water state, the completion of the adjustment of the hot water state is notified by a buzzer or the like.

[Problems to be solved by the invention]

During bathing or the like, the control means may be activated only by a slight decrease in the bathtub water level or temperature. In such a case, in the above-described related art, the completion of the adjustment of the hot water state is frequently notified, and thus there is a possibility that the user may feel uncomfortable.

In order to solve this problem, when the notification operation is performed, it is conceivable to prohibit the notification operation for a predetermined time thereafter (see Japanese Utility Model Laid-Open No. 61-169352).

However, in this case, even when the adjustment amount of the hot water filling state is large and the notification operation is to be performed, the notification operation is not performed within the predetermined time.

An object of the present invention is to provide a bathtub filling device capable of appropriately notifying completion of adjustment of a filling condition while avoiding frequent notification operations.

[Means for solving the problem]

In order to achieve this object, a first characteristic configuration of the bathtub hot-water filling device according to the present invention is that the notifying means is configured so that the notifying means changes from a hot-water state when the control means is activated to a set target hot-water state. The informing operation is performed only when the adjustment amount of the filling state by the adjusting means is larger than the set amount.

The second to fourth characteristic configurations specify preferred specific configurations when implementing the first characteristic configuration.

A second characteristic configuration is that the adjusting unit heats the bathtub water, the target setting unit sets a target temperature of the bathtub water, the detecting unit detects the temperature of the bathtub water, and the control unit detects the temperature of the bathtub water. Controlling the adjusting means so that the temperature of the bathtub becomes a set target temperature, and the notifying means sets a difference between the set target temperature and the temperature of the bathtub water when the control means is activated to a set value or more. That is, it is configured to perform the notification operation only when.

A third characteristic configuration is that the adjusting means supplies hot water to the bathtub, the target setting means sets a target water level of the bathtub water, the detecting means detects a water level of the bathtub water, and the control means makes a control of the bathtub water. The adjusting means is controlled so that the water level becomes a set target water level, and the notifying means is configured such that a difference between the set target water level and the water level of the bathtub water when the control means is activated is equal to or more than a set value. That is, the notification operation is performed only at the time.

In a fourth characteristic configuration, the adjusting means performs heating of the bathtub water and hot water supply to the bathtub, the target setting means sets a target temperature and a target water level of the bathtub water, and the detecting means sets a temperature and a water level of the bathtub water. Detecting, the control means controls the adjusting means so that the temperature of the bathtub water is at the set target temperature, and the water level of the bathtub water is at the set target water level, and the notifying means is configured to control the setting target temperature with the set target temperature. The difference from the temperature of the bathtub water when the control means is activated is equal to or more than a set value,
Alternatively, the notification operation is performed only when the difference between the set target water level and the water level of the bathtub water when the control unit is activated is equal to or larger than a set value.

[Action]

The difference between the hot water state and the target hot water state when the control means is activated corresponds to the adjustment amount of the hot water state. Then, a threshold value set in advance to determine whether the adjustment amount is large corresponds to the set amount.

For example, when the bath is filled with no bath water in the bathtub, the adjustment amount becomes larger than the set amount, and the notification operation is performed when the bath is completed.

On the other hand, when the adjustment amount is smaller than the set amount,
The notification operation is not performed even when the bathing is completed.

〔The invention's effect〕

Since the notification operation is performed only when the adjustment amount of the bathing state is larger than the set amount, a bathtub bath that can appropriately notify the completion of the bathing state adjustment while avoiding frequent notification operations. The device has been obtained.
