Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub control device with hot water supply for detecting and notifying an abnormal state of a human body in a bathtub.

[0002]

2. Description of the Related Art A conventional controller for a bath kettle with a water heater is
As shown in FIG. 2, a water level detecting means 3 for detecting the water level of the bathtub 1, a control section 5 for controlling the operation of the device by judging an increase / decrease in the water level based on a signal from the water level detecting means 3, and the control section. 5 and a remote controller 6 that communicates with the remote controller 5 and displays the status.

[0003]

In recent years, fatal accidents in the bathtub of old people and young children are increasing, and the control device having the above-mentioned configuration detects the water level of the bathtub, but I could not detect the bathing condition due to movement changes,
When a person gets stuck while taking a bath due to sudden illness, no one in the family is aware of the abnormal state, and there is a problem that a fatal accident cannot be prevented.

The present invention solves the above-mentioned conventional problems, and an object thereof is to prevent a fatal accident in a bathtub.

[0005]

In order to solve the above problems, the present invention starts operation by a switch of a remote controller,
A human body detection unit that detects a change in water level that occurs when a person takes a bath, and a notification unit that detects and notifies an abnormal state of the human body when the human body detection unit has not changed the water level due to human movement for a predetermined time It is a thing. According to the above invention, a fatal accident can be prevented in advance by detecting an abnormal state of the human body in the bathtub and notifying it to a person outside the bathroom.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A human body detection unit for detecting a water level in a bathtub and a human body detection unit which starts operation by a switch of a remote controller and detects a fluctuation in water level caused by a signal from the water level detection unit when a person takes a bath. And the human body detection unit for a predetermined time,
It is provided with a notifying means for detecting and notifying an abnormal state of the human body when the water level does not change due to the movement of the person.

When an abnormal state of the human body in the bathtub is detected, the remote control buzzer in the kitchen can inform the person in the kitchen of the abnormal state of the human body in the bathroom.

Further, when an abnormal state of the human body in the bathroom is detected, the remote control speaker in the kitchen can inform the person in the kitchen by voice of the abnormality of the human body in the bathroom.

Further, the remote controller in the kitchen automatically raises the volume when notifying an abnormality of the human body in the bathroom.

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

(Embodiment 1) FIG. 1 is a block diagram of a controller for a bathtub with a water heater according to Embodiment 1 of the present invention. In the figure, 1 is a bathtub, 2 is a bathtub with a water heater connected to the bathtub, 3 is a water level detecting means for detecting the water level, 6 is a kitchen remote controller installed in the kitchen, 8 is a bathroom remote controller installed in the bathroom,
Reference numeral 5 denotes a control unit that communicates with the remote controls 6 and 8 and controls the bathtub 2 with a water heater.

When the control unit 5 receives the hot water signal from the remote controls 6 and 8 to the bathtub, the control unit 5 compares the signal from the water level detection means 3 with the set water level until the set water level set by the remote controls 6 and 8 is reached. Drop it into the bathtub and use remote control 6
And cook until the set temperature set in 8 and 8 is reached.

Then, the control unit 5 judges that a person is bathing when the change in the signal from the water level detecting means 3 increases by a predetermined amount or more, and when the change in the signal from the water level detecting means 3 decreases by a predetermined amount or more. Decides that he is out of the bath.

When the human body detecting switches 7 and 9 of the remote controllers 6 and 8 are pressed, the control unit 5 enters the human body bathing monitoring mode, and the human body detecting unit 4 detects that the water level is constant at a certain period when a person is taking a bath. Since the water level fluctuates, it is judged from the signal from the water level detection means 3 that the user is bathing, and if any abnormality occurs in the person in the bath, it is judged that the water level fluctuation is abnormal for a certain period of time so that the water level is abnormal. Further, when the control unit 5 receives a signal that the human body is in an abnormal state from the human body detection unit 4 during the human body bathing monitoring mode, the control unit 5 notifies the person in the kitchen by the notification means of the kitchen remote controller 6.

(Embodiment 2) The kitchen remote controller 6 has a built-in buzzer as a notification means, and when the control unit 5 receives a signal from the human body detecting unit 4 that the human body is in an abnormal state, the kitchen remote controller 6 A signal indicating that the human body is in an abnormal state is transmitted to the kitchen remote controller 6 and the kitchen remote controller 6 gives a notification by a built-in buzzer.

(Embodiment 3) The kitchen remote controller 6 has a built-in speaker as a notification means, and when the control unit 5 receives from the human body detection unit 4 a signal indicating that the human body is in an abnormal state, the kitchen remote controller 6 will be described. A signal indicating that the human body is in an abnormal state is transmitted to the kitchen remote controller 6, and the kitchen remote controller 6 informs by voice (for example, "an abnormal state has occurred in the bathroom").

(Embodiment 4) Although the kitchen remote controller 6 has a buzzer and a speaker as the notification means, the buzzer and the speaker have a volume switching function.
When the kitchen remote controller 6 receives a signal indicating that the human body is in an abnormal state from the control unit 5, the kitchen remote controller 6 automatically notifies the user by maximizing the volume of the buzzer and the speaker.

[0018]

As described above, according to the present invention, when an abnormal state occurs in the human body in the bathroom, the person in the kitchen is notified and the fatal accident in the bathroom is prevented.
