Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automated structure for cleaning the bathtub and opening and closing the bathtub lid of a bathing device having automatic heating means.

Conventional Structure and Problems Conventionally, when cleaning a bathtub, a user would regularly use detergent and a scrub brush to remove dirt and grime adhering to the inner wall of the bathtub. Regarding opening and closing of the bath lid, as shown in Figs. By detecting the magnetic coupling with the sensor 4, the open/closed state of the bath cover can be detected in a place away from the bathroom (such as the kitchen), and if it detects that it has been forgotten to close, it will go to the bathroom and close it again. Ta. Therefore, it is inconvenient to use and has the unreasonable problem of performing unnecessary operations.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and eliminates the complexity of bathtub cleaning by automatically cleaning the bathtub and opening/closing the bath lid of a bath device having an automatic water supply/drainage machine (+, y). The purpose is to eliminate the problem of forgetting to close the bath lid.

Structure of the Invention In order to achieve the above object, the bath device of the present invention includes a bathtub having a bathing space, a bathtub lid storage space that includes a bathtub cleaning means for cleaning the bathtub, and a bathtub lid that can be opened and closed. A control signal from a bath controller and a detection signal from an entry confirmation sensor that confirms whether or not a person is in the bathroom are inputted to the bath lid control means for controlling the bathtub cleaning means and the bath lid control means. A heating controller is provided to control the heating.

With this configuration, for each preset period,
To automatically wash a bathtub when a bath lid is closed, and to automatically close the bath lid when no one is in the bathroom.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on FIGS. 3 to 8. Note that the same parts as in Fig. 1 are given the same numbers. In FIG. 3, FIG. 4, and FIG. 5, the bath lid 1 has the following:
The bathtub cleaning means S is connected to send cleaning water from a cleaning water tank 8 from a storage space 6 of the bath lid 1 to a cleaning pump 7 using a sprinkler or the like. Further, the bathtub 3 is connected so that pumped water sent under the control of an electric water supply valve 9 is supplied through a hot water supply port 10 and drained by an electric drain valve 12 installed in a drain pipe 11. Further, a heating control means 13 such as a gas instantaneous water heater for heating the hot water in the bathtub 3 is connected to a forced circulation pump 14.
It is connected to the bathtub 3 by a circulation pipe 17 equipped with a water level sensor 15 such as a pressure sensor and a hot water temperature sensor 16 such as a thermistor. The heating control means 13 has a heating controller 20 therein that controls a gas valve 19 etc. that adjusts the amount of gas to the burner 18, and this heating controller 20 is connected to a bath controller 21 installed in the bathroom. , connected to receive control signals and send control signals to the electric water supply valve 9, electric drain valve 12, cleaning pump 7, bath lid control means 22 for automatically opening and closing the bath lid 1, and forced circulation pump 14, respectively. and the magnetic sensor 4
It is connected to input detection signals from a water level sensor 15 and a hot water temperature sensor 16. Bath controller 21
is connected to a remote controller 23 installed in a place other than the bathroom (such as the kitchen), and configured to transmit and receive information such as a heating start signal and a water supply signal. The remote controller also has numeric keys 24 . The bath controller 21 has a control key 25, a buzzer 261, a display means 27, and, as shown in FIG. It has a control key 29.

As shown in Fig. 8, two sets of optical coupling circuits for the light emitting elements 31.32 and the infrared receiving elements 33.34 are provided on both sides of the bathroom entrance aOυ-. It is connected to send a detection signal to the bath controller 21.

In the above configuration, when the bathtub 3 is to be boiled from an empty state, the user first presses the remote controller 23 using the number keys 24. Using the control keys 25 and the like, the boiling point temperature, boiling time, boiling water level, etc. are input while looking at the display means 27. The remote controller 23 periodically sends control signals to the bath controller 2-1 based on these input control information, and receives and monitors monitor information. bath controller 2
1 first closes the electric drain valve 11, and if the bath lid 1 is open, sends a closing signal to the bath lid control means 22 and opens the electric water supply valve 9. Next, at the same time that a certain amount of water is supplied to the bathtub 3, the heating controller performs a heating operation, the gas amount to the burner 18 is controlled by the gas valve 19, the circulation pump 14 is operated, and the water level sensor 15. A detection signal from the hot water temperature sensor 16 is sent to the bath controller 21. After boiling, when taking a bath, the optical coupling circuit of the bathroom entrance part 30, which is necessary for entering the bathroom, is cut off, and when entering the bathroom, the optical coupling circuit of the light emitting element a1 and the light receiving element 33 is cut off. After cutting off, the optical coupling circuit between the light emitting element 32 and the light receiving element 34 is cut off. The opposite is true when leaving the bathroom. Therefore, the heating controller 20 can always detect the presence of a person in the bathroom by inputting this detection signal. You can close the bath lid when you leave the bathroom. In addition, by switching the control key 29 of the bath lid to manual mode using the bath remote control 21, the bath cover can be opened and closed manually.

After bathing (when the bathtub 3 is empty), press the cleaning control key 25 on the remote controller 23 to close the bath lid 1.
After closing the cleaning water tank 8, the cleaning pump 7 closes the cleaning water tank 8.
The washing water is force-fed to the bathtub washing means 5, and is sprayed onto the inner wall of the bathtub to wash it.

Therefore, it is no longer necessary to go to the bathroom every time you take a bath and close the bath lid, or to open and close the bath lid manually every time you take a bath, and you can also clean the bathtub with one touch from the remote controller, making it easy to use. This will reduce heat radiation loss caused by forgetting to close the bathtub lid.

Effects of the Invention As described above, according to the bath device of the present invention, there is provided a bathtub having a bathing space and a storage space for a bathtub lid that includes a bathtub cleaning means for cleaning the bathtub, and the opening and closing of the bathtub lid is controlled. A control signal from a bath controller and a detection signal from an entry confirmation sensor that confirms whether or not a person is in the bathroom are input to control the bathtub cleaning means and the bathtub lid control means. By installing a heating controller, the bathtub can be automatically cleaned at regular intervals and the bathtub lid can be opened and closed automatically, further improving usability such as eliminating the complexity of bathtub cleaning and preventing forgetting to close the bathtub lid. The effect of doing so can be obtained.
