Description

  In order to avoid accidents during bathing, the present invention incorporates a human sensor, a photoelectric sensor, and a bathtub stopper / removal device that dynamically captures the movement of the bathtub and washing area in the bathroom. It relates to automatic equipment.

  Fatal accidents at home are concentrated in the bathroom, and the number of accidental deaths in the bathroom exceeds about 14,000 per year, especially among the elderly who are taking a sudden bath. Typical cases in the bathtub include losing consciousness due to seizures such as heart disease, convulsions, and seizures while taking a bath alone, and drowning due to submergence of the head, and a fall accident in a washroom.

  Factors that prevent the body from moving due to disturbance of consciousness during bathing account for 80% of cardiovascular diseases such as heart infarction and brain diseases such as intracerebral hemorrhage. There is an example where it was too late for a family member to find an accident because they did not come out of the bathroom. Such an accident is not limited to the elderly, but the subject may be an infant whose feet slipped, and even a healthy young person may be drowning from a coma while taking a bath in a drunken state after drinking.

  Conventionally, a method has been proposed in which a bathing monitoring device is floated in a bathtub, and when a calm state is formed so as to become a trap while the waves decay, an alarm sounds and the bather's body movement is monitored and an alarm is issued. However (see Patent Document 1) Since the wave in the bathtub becomes quiet in 2 to 3 seconds, there is a problem that there are many false alarms.

  There is a method in which the bathing time is set with a timer in advance, and when the time elapses, a call button is installed in the bathroom, or if the bather is aware of his / her abnormality, he / she presses the call button to inform the family living together (Patent Document 2 And Patent Document 3). However, there is no guarantee that a person who has actually become sick will press the call button calmly.

  Regardless of the intention of the bather, there is a system in which a camera is installed in the bathroom and the housekeeper monitors the inside of the bathroom. There is an advantage that the state of the bather is obvious and reliable. Some of the images in the bathroom are displayed outside the bathroom after being subjected to a correction treatment such as mosaic (see Patent Document 5), but these have privacy problems such as lack of consideration for the shame of the bathing subject. The monitoring side needs to pay attention to it, and there is a drawback that the time of the monitoring person is restricted.

  In combination with a telephone notification system using an anomaly detection device, it has been proposed to report anomalies to a specific person at a remote location. However, in the case of a submergence accident, if there is a quick response, the resuscitation rate is high, and there is a need for a device that is suitable for this situation.

  When introducing a device proposed so far into a general home, the device is installed in an existing bathtub, which is not practical and the construction cost is high for replacement and expansion, thus preventing the spread of the device.

  In the current situation where there are many accidents in the bathroom, drowning due to submergence in the bathtub and the accident of falling over the washing area are the most common, but in the prior art, only an accident in the bathtub is proposed, and there is no proposal for an accident in the washing area. An object of the present invention is to realize a device that simultaneously solves an accident in a bathtub and an accident in a washing place.

  The present invention provides a simple automatic accident prevention apparatus in a bathroom that allows a bather to quickly detect an accident in a bathtub or a washing place, prevent a serious accident in advance, and is excellent in cost.

  In the present invention, photoelectric sensors are installed in a part of a bathtub 6 and a washing place 7 in a bathroom as shown in FIG.

  Send to the mobile phone or the emergency call system of each body via a wireless network.

  Turn on the lighting switch 1A in the bathroom. When the bather 8 enters the room and passes, the human sensor 2 detects the timer 2B. At the same time, the photoelectric sensor projector 3 and the photoelectric sensor receiver 4 operate, and the reflected light 4D detects the bather 8 and a melody sounds. It keeps ringing while the bather 8 is in the washing place 7 and the bathtub 6. The structure is such that the entire system ends when it passes through the human sensor 2 when leaving the room.

  If a fall or submergence accident occurs, the bather 8 goes out of the detection range of the projection light 3C emitted from the photoelectric sensor projector 3, and the melody disappears and is converted into a different danger signal sound by the detection relay. Inform. Moreover, it is a structure that can automatically transmit a danger signal to a mobile phone or the like (emergency call system) in conjunction with it.

  As described above, the present invention has a structure in which the stopcock detaching device 9 operates simultaneously with the notification of the danger signal, drains hot water in the bathtub in 1 to 2 minutes, and avoids the worst drowning.

  The automatic accident prevention apparatus in the bathroom of the present invention has a structure in which the bather can adjust the detection distance and the measurement range and the operation area of the wide-angle light projection with the photoelectric sensor. The photoelectric sensor includes the photoelectric sensor projector 3 and the light receiver 4. It is configured. The amount of light reaching the light receiver 4 is changed by the projection light 3C, and the light receiver 4 detects this change, converts it into an electrical signal, and outputs it. The human sensor 2 is a sensor that detects infrared rays. At the same time, it is drained by a stopcock desorption device and exhibits the effect of preventing a serious accident.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  1 and 2, when the lighting switch 1A of the bathing entrance 1 is input, the human sensor 2 is activated, the timer 2B provided in the bathroom, the photoelectric sensor 3, the stopcock attaching / detaching device 9, the speaker 5, and the mobile phone Or linked to the emergency call system.

  When the bather 8 passes through the bathroom entrance 1, the human sensor switch 2 detects and interlocks with the timer 2 </ b> B and the entire system. Photoelectric sensor projector 3 The photoelectric sensor receiver 4 is installed in the bathtub 6 and the washing place 7. There are a method of installing it upward about 20 cm to 30 cm from the upper part of the bathtub 6 (FIG. 4), and a method of installing the photoelectric sensor projector 3 light receiver 4 on the ceiling (FIG. 3). Both are installed according to the site environment. The timer 2B presets the bathing time, and notifies the elapsed time measured by the notification means speaker 5 through the notification means speaker 5.

  In order to prevent the drowning of the bather 8 by detecting the submergence of the bather 8 at the same time as warning to the outside of the house or notifying the mobile phone etc. The stopper removal device 9 of the bathtub 6 is activated, the drain valve 12 is opened, the hot water in the bathtub 6 is drained in a short time to avoid drowning, and the worst situation is avoided.

  As shown in FIGS. 5 and 6, when the stop lever detaching device 9 is set to push down the manual lever 20 during bathing, the insertion / removal protrusion rod 14 enters and is fixed to the protrusion insertion / removal port 15 in the rotation stop plate 16. When the danger signal of the occurrence of the accident is caught, the insertion / removal projection rod 14 is released by the cylindrical coil 13, and the rotation stop plate 16 returns to the original position. The drainage valve 12 is drawn out from the drainage port 11 through the connected chain 10 and drained to ensure safety from the worst state of the bather 8. Needless to say, the drain valve 12 of the stopcock removal apparatus 9 can be equipped with a solenoid valve in the drain port 11 in addition to the above.

  The in-bathroom behavior detection device main body 21 includes a sensor unit, a signal processing circuit, a control unit, an in-bathroom alarm generation unit, and an out-bathroom notification unit.

  The timer 2B described in the previous section “0014” will be described. The bather 8 falls within the detection range of the photoelectric sensor projector 3 even though the bather 8 falls into a consciousness disorder in the bathtub 6 and the washing place 7 and is in a critical state. You may not be able to confirm the dangerous state. In such a case, the bathing time by the timer 2B is set as the role of the safety net, and the bathing elapsed time is notified to the bather 8 and the housekeeper in the house by the speaker 5.
