Similarly, the blood pressure sensor is configured to detect the blood pressure of the bather in a non-contact state with the bather. Similarly, the electrocardiogram sensor is configured to detect the bather's electrocardiogram without contact with the bather.

  The position information of the person in the bathroom 14 detected by the human sensor as the biological information sensor 52 is transmitted to the control unit 46. Further, the information on the heart rate of the bather detected by the heart rate sensor as the biological information sensor 52 is transmitted to the control unit 46. Further, the blood pressure information of the bather detected by the blood pressure sensor as the biological information sensor 52 is transmitted to the control unit 46. Further, the bather's electrocardiogram information detected by the electrocardiogram sensor as the biological information sensor 52 is transmitted to the controller 46. The control unit 46 processes the position detection signal output from the human sensor, thereby specifying the position of the person in the bathroom 14. Further, in the control unit 46, the heart rate of the bather is measured by processing the heart rate detection signal output from the heart rate sensor. Similarly, in the control part 46, the blood pressure of the bather is measured by processing the blood pressure detection signal output from the blood pressure sensor. Similarly, in the control part 46, the electrocardiogram of a bather is measured by processing the electrocardiogram detection signal output from the electrocardiogram sensor. The control unit 46 outputs signals corresponding to the bather's position information, bather's heart rate information, bather's blood pressure information, and bather's electrocardiogram information from the communication unit 48 to the control unit 54, respectively. The control unit 46 also outputs a signal corresponding to the operation of each button or the like from the communication unit 48 to the control unit 54 when the operation of each button or the like is performed on the operation unit 44.

This is input to the part 58.

  The biological information sensor 52 functions as a bathing state detection unit that detects a predetermined bathing state in which a bather in the bathtub 18 may become abnormal. For example, when the controller 58 detects that there is no movement of the bather for a predetermined time or more based on the position information of the bather in the bathtub 18 detected by the human sensor as the biological information sensor 52, It is determined that a predetermined bathing state in which a bather in 18 can become abnormal. Alternatively, when the heart rate of the bather detected by the heart rate sensor as the biological information sensor 52 becomes equal to or higher than a first threshold value as an example of a predetermined heart rate, the control unit 58 It is determined as a predetermined bathing state in which the bather can become abnormal. Alternatively, when the blood pressure of the bather detected by the blood pressure sensor as the biological information sensor 52 is equal to or higher than a second threshold value as an example of the predetermined blood pressure, the bather in the bathtub 18 may become abnormal. Judged as a bathing condition. Alternatively, when the information read from the electrocardiogram of the bather detected by the electrocardiogram sensor as the biological information sensor 52 satisfies a certain condition, the bather in the bathtub 18 is determined to be in a predetermined bathing state that may become abnormal. . When it is determined that the bathing state is a predetermined state, the control unit 58 operates the moving device 30 and moves the distal end portion 32 </ b> A of the lever 32 to a position far from the drain port 22 (see FIG. 3) by the actuator 34. As a result, the lever 32 pulls the chain 26 in the direction of arrow A to move the drain plug 24 from a position where the drain port 22 is closed to a position where the drain port 22 is opened.

  In the present embodiment, when the absolute value of the bather's heart rate is equal to or greater than the first threshold value, the moving device 30 is operated. However, the change (increase) in the bather's heart rate is a predetermined amount. The mobile device 30 may be operated when the heart rate becomes equal to or greater than the change value (rise value). Similarly, in the present embodiment, when the absolute value of the bather's blood pressure becomes equal to or greater than the second threshold, the moving device 30 is operated. The moving device 30 may be activated when the blood pressure change value (increased value) is exceeded.

  The control unit 58 operates the actuator 34 to move the tip 32A of the lever 32 to a position far away from the drain port 22 (see FIG. 3), and then operates the actuator 34 when a predetermined condition is satisfied. Return the tip 32A of the lever 32 to the original position (see FIG. 1). In this embodiment, the control unit 58 (1) when a predetermined time (for example, 12 hours) has elapsed since the actuator 34 was operated, (2) the operation switch (not shown) of the remote controller 40 is turned off and on. When both of the state operations are performed, (3) when the bath automatic button (not shown) of the remote controller 40 is pressed to perform automatic hot water filling, when any one of the conditions is satisfied, the actuator 34 is operated to return the tip 32A of the lever 32 to the original position (see FIG. 1).

  Next, the operation and effect of this embodiment will be described.

<During normal bathing>
As shown in FIG. 1, when hot water is applied to the bathtub 18, the tip end portion 32 </ b> A of the lever 32 moves to a position close to the drain port 22. Furthermore, in a state where the drain outlet 22 is blocked by the drain plug 24, for example, a bath automatic button (not shown) of the remote controller 40 is pressed, so that hot water is stored in the bathtub 18.

<When an abnormality is detected>
When the control unit 58 determines that an abnormality has been detected under a predetermined condition based on the biological information detected by the biological information sensor 52 (see FIG. 2 and the like), the control unit 58 enters the drainage mode. For example, when the controller 58 detects that there is no movement of the bather for a predetermined time or more based on the position information of the bather in the bathtub 18 detected by the human sensor as the biological information sensor 52, the biological information The bather detected by the blood pressure sensor as the biological information sensor 52 when the heart rate of the bather detected by the heart rate sensor as the sensor 52 is equal to or higher than the first threshold value as an example of the predetermined heart rate. The information that can be read from the electrocardiogram of the bather detected by the electrocardiogram sensor as the biological information sensor 52 satisfies a certain condition when the blood pressure of It is determined that an abnormality has been detected. Accordingly, the drain mode is set, and the control unit 58 operates the moving device 30 and moves the tip end portion 32A of the lever 32 to a position far from the drain port 22 by the actuator 34, as shown in FIG. As a result, the lever 32 pulls the chain 26 in the direction of arrow A, and moves the drain plug 24 from a position where the drain port 22 is closed to a position where the drain port 22 is opened. By opening the drain port 22, the hot water in the bathtub 18 is drained from the drain port 22.

  In such a drainage system 12, the control unit 58 activates the moving device 30 when the biological information sensor 52 detects a predetermined bathing state in which the bather in the bathtub 18 may become abnormal, and thereby the drainage port The drain plug 24 is moved from a position where the drain 22 is closed to a position where the drain port 22 is opened. Thereby, the hot water in the bathtub 18 is drained from the drain port 22. For this reason, it is possible to prevent the bather from drowning in the bathtub 18 when the bather loses consciousness, for example. Even in a bathtub provided with a normal drain plug 24 other than the automatic drain plug, the hot water in the bathtub 18 can be drained in the event of an abnormality.

  In the drainage system 12, the moving device 30 includes a lever 32 connected to the chain 26 on the upper portion 18 </ b> A side of the bathtub 18 (in this embodiment, on the upper side of the side portion 20). Then, by moving the lever 32 in a direction in which the chain 26 is pulled by the actuator 34, the drain plug 24 is moved from a position where the drain port 22 is blocked to a position where the drain port 22 is opened. For this reason, the hot water in the bathtub 18 can be drained using the chain 26 originally connected to the drain plug 24.

  Furthermore, in the drainage system 12, the biological information sensor 52 includes a heart rate sensor that detects the heart rate of the bather in the bathtub 18, a human sensor that detects the position of the bather, a blood pressure sensor that detects the blood pressure of the bather, And at least one electrocardiogram sensor for detecting a bather's electrocardiogram. The control unit 58 operates the moving device 30 based on the bathing state of the bather based on information detected by at least one of a heart rate sensor, a human sensor, a blood pressure sensor, and an electrocardiogram sensor. Thereby, for example, when the bather's heart rate and blood pressure are higher than allowable values, or when the bather does not move, the hot water in the bathtub 18 can be drained from the drain port 22.

  The drainage system 12 is provided with a remote controller 40 in which a speaker 50 that outputs sound is disposed in the bathroom 14, and the control unit 58 allows hot water in the bathtub 18 to flow before operating the moving device 30. You may make it alert | report to a bather from the speaker 50 that it drains. Thereby, it is avoided that the hot water in the bathtub 18 is suddenly drained without notifying the bather in advance.

  In the drainage system 102, as shown in FIG. 4, during normal bathing, the chain 104 is pulled out from the winding wheel 108, and the drainage port 22 is blocked with a drainage plug 24. The control unit 58 activates the moving device 106 when the biological information sensor 52 (see FIG. 5) detects a predetermined bathing state in which the bather in the bathtub 18 may become abnormal (when it is determined that abnormality has been detected). Let That is, as shown in FIG. 6, the control unit 58 rotates the motor 112 to rotate the winding wheel 108 in the arrow B direction. As a result, the chain 104 is wound around the winding wheel 108, and the drain plug 24 connected to the chain 104 moves from a position where the drain port 22 is blocked to a position where the drain port 22 is opened. As a result, the hot water in the bathtub 18 is drained from the drain port 22. For this reason, it is possible to prevent the bather from drowning in the bathtub 18 when the bather loses consciousness, for example. Even in a bathtub provided with a normal drain plug 24 other than the automatic drain plug, the hot water in the bathtub 18 can be drained in the event of an abnormality.

  In the drainage system 102, the hot water in the bathtub 18 can be drained using the chain 104 originally connected to the drain plug 24. Furthermore, since the chain 104 is wound up by the rotation of the winding wheel 108, it is easy to apply force to the chain 104 with less torque than the lever 32 (see FIG. 1) of the first embodiment.

  In the drainage system 102 of the second embodiment, the winding wheel 108 is exposed in the bathtub 18, but the present invention is not limited to this configuration. For example, in the drainage system, a winding car or a motor as a moving device is arranged inside the side wall 20A of the side part 20, a chain is inserted into a hole formed in the side wall 20A, and the chain is rotated by rotation of the winding car. It is good also as a structure wound up. In this drainage system, the winding wheel and the motor as the moving device are hidden inside the side portion 20, and only the chain is projected into the bathtub 18 from the hole of the side wall 20A. Can be improved.

[Third Embodiment]
Next, the bathroom system 130 provided with the drainage system 132 according to the third embodiment of the present invention will be described with reference to FIGS. 7 and 8. In addition, about the same component as 1st and 2nd embodiment mentioned above, the same number is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 7, in the drainage system 132 of the present embodiment, the drainage port 22 is opened from the position where the drainage port 22 is closed instead of the moving device 30 (see FIG. 1) of the drainage system 12 of the first embodiment. A moving device 136 is provided as a moving means for moving the drain plug 24 to the position where it is to be moved. One end of the chain 134 as a connecting member in the longitudinal direction is attached to the upper part 18A side of the bathtub 18 (in this embodiment, the upper side of the side wall 20A). The head 24 </ b> B of the drain port 22 is connected to the head.

  The moving device 136 is disposed on the lower side in the vertical direction with respect to the drain port 22 of the bottom portion 19 of the bathtub 18. More specifically, the moving device 136 includes a motor 138 as a drive unit supported by the support unit 142 below the drain port 22 of the bathtub 18 in the vertical direction, and a rod that moves in the vertical direction by the rotation of the motor 138. 140. For example, the rod 140 is configured to move upward in the vertical direction by the forward rotation of the motor 138 and push up the drain plug 24 from the drain port 22 (see FIG. 8). Moreover, the support part 142 is being fixed to the installation surface 144 in which the bathtub 18 is installed as an example. The control unit 58 (see FIG. 5) controls the operation of the motor 138.

  In the drainage system 132, as shown in FIG. 7, during normal bathing, the rod 140 moves downward in the vertical direction from the position where the drainage plug 24 blocks the drainage port 22. In this state, hot water is stored in the bathtub 18 by the drain plug 24 closing the drain port 22. The control unit 58 (see FIG. 5) detects a predetermined bathing state in which the bather in the bathtub 18 may become abnormal (when it is determined that abnormality has been detected) by the biological information sensor 52 (see FIG. 5). The moving device 136 is activated. That is, as shown in FIG. 8, the control unit 58 rotates the motor 138 to move the rod 140 upward in the vertical direction indicated by the arrow C. Thus, the drain plug 24 is pushed up from the drain port 22 by being pushed by the rod 140, and the drain port 22 is opened (the drain plug 24 is detached from the drain port 22). As a result, the hot water in the bathtub 18 is drained from the drain port 22. For this reason, it is possible to prevent the bather from drowning in the bathtub 18 when the bather loses consciousness, for example. Even in a bathtub provided with a normal drain plug 24 other than the automatic drain plug, the hot water in the bathtub 18 can be drained in the event of an abnormality.

  In addition, the rod 140 is returned to the original position (refer FIG. 7) by reverse rotation of the motor 138, when predetermined conditions are satisfy | filled similarly to the drainage system 12 (refer FIG. 1) of 1st Embodiment.

  In the drainage system 132 described above, the rod 140 is provided below the drainage port 22 of the bathtub 18 in the vertical direction, so that the design of the bathtub 18 is not impaired. Further, since the rod 140 is moved upward and downward by the rotation of the motor 138, the drain plug 24 can be forcibly pushed up from the drain port 22 with a strong force regardless of the strength of the chain 134.

  In the first to third embodiments, one biological information sensor 52 is provided in the remote controller 40, but the present invention is not limited to this configuration. For example, any number of biological information sensors may be installed at other positions such as a bathroom ceiling or in a bathtub.
