Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath facility, more specifically, a water heater, a heater for heating a bathroom or a dressing room, and a hot water heater based on an automatic filling command from a command means. The present invention relates to a hot water supply control means that is activated to start hot water filling of a bathtub and, when the amount of hot water supplied to the bathtub reaches a set amount, performs hot water filling control for stopping hot water supply to the bathtub.

[0002]

2. Description of the Related Art In a conventional bath facility of this type, a heater is configured to be activated only by manual operation.

[0003]

However, according to the above-mentioned conventional technique, when the bath is used, it may not be heated due to unavoidable forgetting operation.

An object of the present invention is to ensure that heating is performed when a bath is used and that the bath can be comfortably used.

[0005]

According to the present invention as set forth in claim 1, an automatic heating control means is provided to perform heating control for operating a heater when a hot water filling command is issued. That is, since it is configured to perform automatic heating, the bathroom and dressing room are always heated when the bath is used after the filling of water is completed. As a result, according to the present invention, the bath and dressing room are reliably heated when the bath is used, and the bath can be used comfortably.

According to the second aspect of the present invention, a heating switch is provided so that the automatic heating is performed only in the cold season when heating is required, such as in winter, and is not performed when the heating is unnecessary such as in summer. As a result, it has become possible to reduce running costs by preventing unnecessary heating while automatically performing heating in cold seasons such as winter to comfortably use the bath.

According to the third aspect of the present invention, whether or not heating is required is detected by the inspection means, and the heating control based on the automatic filling command is executed only when the detection result indicates that the heating is required. Therefore, by automatically operating and stopping the automatic heating based on the automatic filling command, you can always heat the bathroom and dressing room when you need to heat in cold weather such as winter, and you can comfortably use the bath, while in summer etc. When heating is not needed, it is possible to reduce running costs by preventing unnecessary heating.

By the way, in the bath facility, the temperature of water supplied to the water heater is low and the temperature of the bathtub and the changing room is low in cold seasons such as winter when heating of the bathroom and changing room is required. The water heater is provided with a water temperature sensor that detects the temperature of the water when performing appropriate temperature hot water supply, while the heater is provided with a heating temperature sensor when performing appropriate temperature heating. .

In view of the above point, according to the present invention of claim 4, since the inspection means is a means for detecting whether or not heating is required by using the water supply temperature to the water heater as a parameter, the heating is performed. Whether or not is necessary can be performed by using existing devices, and the structure can be simplified and the cost can be reduced.

Further, in view of the above point, according to the present invention of claim 5, since the means for detecting whether or not the heating is necessary by using the room temperature as a parameter is provided as the inspection means, the necessity of the heating is provided. The presence or absence can be checked by using existing devices, and the structure can be simplified and the cost can be reduced.

By the way, if the window is opened during heating, the room temperature cannot be set to a predetermined room temperature, and the heating efficiency is remarkably lowered, resulting in a great energy loss.

Focusing on the above point, according to the present invention of claim 6, a window inspection means is provided to detect opening and closing of the window, and the opening of the window is detected by the window inspection means. Then, the notification control means operates the notification means to notify the user of the fact that the window is open. Therefore, if the window is open during heating, the user is notified of that fact. You can urge the user to close the window. as a result,
According to the present invention, heating can be performed with little loss.

According to the seventh aspect of the present invention, when the notification control is executed, the execution of the heating control based on the automatic water filling command is stopped so that the heating in the state where the window is open is stopped. Since it is configured, it is possible to prevent useless heating even when the user is in a condition such that the window cannot be closed and operated due to absence.

According to the present invention of claim 8, the first remote controller provided in the dressing room and the second remote controller provided in a place other than the dressing room are provided with informing means to open the window during automatic heating. Since the notification is made, the notification performance for the user can be made excellent.

Is. That is, the opening / closing of the window W is determined by the degree of increase in the room temperature caused by operating the bathroom heater A based on the automatic water filling command.

Next, the operation of the automatic heating control will be described. As shown in FIG. 7, when the hot water filling flag is turned on, the heating switch S is turned on, and the inspection means Y detects that the detected temperature is below the set temperature, heating is started. With the start of this heating, we check the opening and closing of the window,
When the window W is opened upon completion of the check, the buzzer 70 is sounded to perform the notification control, and then the water filling flag is turned off.
On the other hand, if it is closed, it is determined whether or not the set time has timed up. If the time is up, the water filling flag is turned off and then heating is stopped.

The buzzer 70 is a heater remote controller A1.
And a main remote controller (second remote controller) B1.

[Other Embodiments] In the above embodiment, the inspection means Y is a means for detecting whether or not heating is required by using the feed water temperature as a parameter. However, as the inspection means, as shown in FIG. It may be a means for detecting the presence or absence of heating with room temperature as a parameter. That is, if the room temperature is equal to or lower than the set temperature (for example, 10 ° C.), it is detected that heating is necessary.

In the above embodiment, the opening / closing of the window W is discriminated by the degree of increase in the room temperature due to the operation of the heater A. However, the window W is provided with a position detection switch such as a limit switch or a proximity switch. The opening / closing of the window W may be determined.

In the above-mentioned embodiment, the water heater B is a two-can / three-water heater, but the water heater B may be a one-can / three-water heater.

In the above-described embodiment, the bathroom heater is shown as the heater A, but the heater A targets the dressing room C1 for heating, or the bathroom C and the dressing room C1. It may be one.

Although the window W is shown as the window of the bathroom C in the above embodiment, the window W may be the window of the dressing room C1 or the windows of the bathroom C and the dressing room C1.
