Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for filling a bathtub with water, more specifically, a water heater is provided, and the water heater is operated to fill the bathtub based on an automatic water filling command from a command means. The present invention relates to an apparatus provided with hot water supply control means for executing hot water filling control that starts hot water supply and stops hot water supply to a bathtub when the amount of hot water supply to the bathtub reaches a set amount.

[0002]

2. Description of the Related Art In this type of bath filling device, it is convenient that a predetermined amount of hot water can be placed in the bath by simply issuing an automatic filling command by operating a filling switch.
Conventionally known as such a bath filling device is a device that causes the hot water supply control means to execute only the filling control based on an automatic filling command.

[0003]

However, according to the above conventional technique, if the window of the bathroom or dressing room is closed,
Even in the cold season such as winter, it is possible to prevent the bathroom and dressing room from being over-cooled due to the outside air entering the bathroom and dressing room. Although it is possible to use it comfortably, if you forget to close the window or if you misunderstand that you closed it, you will not be able to warm it sufficiently even if you heat it, and you will not be able to use the bath comfortably.

An object of the present invention is to enable automatic water filling with the window closed.

[0005]

According to the present invention as set forth in claim 1, the notifying control means operates the notifying means if the window is opened and closed based on the automatic filling command. Since it is configured, the user can be prompted to close the window and the window closing operation can be encouraged.

As a result, according to the present invention, when the bath is used,
It is possible to avoid the coldness of the bathroom and dressing room as much as possible, and to use the bath comfortably.

According to the second aspect of the present invention, since a heater is provided to heat the bathroom or dressing room at the same time when the automatic filling of water is started, it is comfortable to use the bath in cold weather such as winter. It can be anything.

Furthermore, since the degree of increase in the room temperature is small when the window is open, the opening / closing of the window is discriminated based on the degree of increase in the room temperature accompanying the heating. No configuration is required on the window to determine

As a result, according to the present invention, the opening / closing of the window can be easily discriminated by effectively utilizing the heating for comfortable use of the bath.

According to the third aspect of the present invention, since the heater is configured to heat the room by circulating the air, the entire room can be heated uniformly.

According to the fourth aspect of the present invention, since the room heating and the room drying are performed by the heater, the room is heated when the bath is used, but the room is heated after the bath is used. By performing the drying, it is possible to maintain the bathtub and the dressing room, which tend to be wet, in a dry state, and prevent the durability of the bathtub and the dressing room from being deteriorated due to the humidity.

According to the fifth aspect of the present invention, the notifying means is provided in the undressing room to notify the user of the open / closed state of the window before entering the bathroom. I was able to inform the user of the open / closed state of the window, and I was able to use the bath more comfortably.

According to the fifth aspect of the present invention, since the notification means is incorporated in the first remote controller provided in the dressing room and the second remote controller provided in a place other than the dressing room, the notification performance for the user is improved. Can be excellent.
