For example, it is conceivable to use a magnetic sensor as an open / close detection unit for a bathroom door, which is less affected by impact and water adhesion. There is a gap between the frame of the bathroom door and the shoji screen due to manufacturing tolerances and a gap for providing a waterproof material. The magnetic field detected by the magnetic sensor decreases as the distance from the magnet increases. Therefore, it is conceivable to use a magnet having a strong magnetic force, but there is a risk that the size of the magnet will increase and the cost will increase. It is also possible to increase the sensitivity of the magnetic sensor, but since noise detection is also increased, there is a risk that stable opening / closing detection accuracy cannot be obtained.

The bathroom door unit 20 includes a bathroom door 30 and an open / close detection unit 60. Further, the bathroom door unit 20 includes a control unit 80. The bathroom door 30 is installed between the dressing room 1 and the bathroom 6. The bathroom door 30 includes a frame body 32 and a shoji screen 40.

The frame 32 forms an entrance / exit 32a between the dressing room 1 and the bathroom 6. The doorway 32a has, for example, a substantially rectangular shape. The frame body 32 has a substantially rectangular frame shape formed of, for example, an aluminum material. The frame body 32 includes a lower frame portion 33 arranged on the floor surface, a first vertical frame portion 34 rising upward from one side in the longitudinal direction of the lower frame portion 33, and the other side in the longitudinal direction of the lower frame portion 33. It has a second vertical frame portion 35 that rises upward from the top, and an upper frame portion 36 that connects the upper ends of the first vertical frame portion 34 and the second vertical frame portion 35. The doorway 32a is a portion surrounded by a lower frame portion 33, a first vertical frame portion 34, a second vertical frame portion 35, and an upper frame portion 36. The first vertical frame portion 34 is located, for example, on the shaft portion side of the shoji 40 and extends in the vertical direction.

The second vertical frame portion 35 faces the first vertical frame portion 34 in the horizontal direction (horizontal direction). The second vertical frame portion 35 is arranged on the side opened by the shoji 40. The second vertical frame portion 35 is a first plate portion 35a located on the bathroom 6 side and extending laterally from the wall portion 6a of the bathroom 6, and a second plate extending from the first plate portion 35a toward the dressing room 1 side. It has a portion 35b and. The second vertical frame portion 35 is formed by the first plate portion 35a and the second plate portion 35b in an L-shaped cross section.

In the second vertical frame portion 35, the second plate portion 35b faces the door end portion 46 of the shoji 40 in the lateral direction. The second vertical frame portion 35 has a unit mounting hole 35c on the upper end side (upper frame portion 36 side) to which the sensor unit 70 described later is mounted.

As shown in FIG. 7, in the second vertical frame portion 35, the first plate portion 35a is connected to the wall portion 6a of the bathroom 6 by the joiner 50. The joiner 50 is formed of a magnetic material such as iron or nickel, and extends in the vertical direction on the back surface side of the wall portion 6a and the first plate portion 35a. The joiner 50 connects the wall portion 6a and the second vertical frame portion 35, and suppresses water from leaking from the bathroom 6 to the outside.

The shoji 40 is supported so as to be openable and closable with respect to the frame body 32. The shoji 40 has, for example, a first door portion 42 and a second door portion 45. The first door portion 42 has a shaft support portion 43 pivotally supported by the frame body 32. The shaft support portion 43 extends in the vertical direction along the first vertical frame portion 34. The shaft support portion 43 is pivotally supported by the lower frame portion 33 and the upper frame portion 36 of the frame body 32 in the vertical direction.

The second door portion 45 has a door tip portion 46 provided at a position laterally separated from the shaft support portion 43. The door tip portion 46 extends in the vertical direction along the second vertical frame portion 35. That is, in the shoji 40, the shaft support portion 43 is located at one side end of the shoji 40, and the door tip portion 46 is located at the other side end of the shoji 40. When the shoji 40 is closed, the door tip portion 46 is close to the second plate portion 35b of the second vertical frame portion 35.

The door tip portion 46 has a sliding portion 46a slidably engaged with the upper frame portion 36 and the lower frame portion 33 at the upper end portion and the lower end portion (upper sliding portion in FIGS. 5 and 6). Only 46a is shown). The shoji 40 opens and closes the doorway 32a by moving the sliding portion 46a toward the first vertical frame portion 34 with respect to the frame body 32 with the shaft support portion 43 as the axis.

Further, the door tip portion 46 has a case mounting hole 46b on the upper end side to which the magnet case 61 described later is mounted. The case mounting hole 46b is provided at a position corresponding to the unit mounting hole 35c of the second vertical frame portion 35. In this example, the case mounting hole 46b is open to the bathroom 6 side with the shoji 40 closed.

The first door portion 42 and the second door portion 45 are, for example, substantially rectangular flat plates. The vertical lengths of the first door portion 42 and the second door portion 45 are substantially the same as or slightly shorter than the vertical length of the doorway 32a. The lateral lengths of the first door portion 42 and the second door portion 45 are substantially the same as or slightly shorter than half the lateral length of the doorway 32a. As a result, the doorway 32a can be closed by arranging the first door portion 42 and the second door portion 45 side by side.

In this example, the shoji 40 is a folding door in which the first door portion 42 and the second door portion 45 are bendable. The first door portion 42 and the second door portion 45 rotate toward the bathroom 6 side when moving to the open position.

Next, the open / close detection unit 60 will be described.

The open / close detection unit 60 detects the open / closed state of the shoji 40. As shown in FIG. 3, the open / close detection unit 60 is provided on the upper end side of the frame body 32 and the shoji 40. The open / close detection unit 60 is provided, for example, at a height of about 1800 mm to 1900 mm from the floor surface of the bathroom 6. The open / close detection unit 60 has a magnet 62 and a sensor unit 70.

The magnet case 61 is attached to the case mounting hole 46b of the second door portion 45. The magnet case 61 is made of, for example, a resin material. As shown in FIGS. 5 and 7, the magnet case 61 includes a main body portion 61a, an engaging portion 61b provided in the main body portion 61a and engaged with the case mounting hole 46b, and a storage portion 61c for accommodating the magnet 62. , Have.

The magnet case 61 is attached to the door tip portion 46 of the shoji 40 by engaging the engaging portion 61b with the case mounting hole 46b in a state where the magnet 62 is housed in the storage portion 61c. That is, a magnet 62 is provided on the door tip 46 of the shoji 40.

The magnet 62 is formed in a columnar shape in which, for example, the S pole and the N pole are located in the axial direction (longitudinal direction). Then, the magnet 62 is housed in the storage portion 61c of the magnet case 61 so that the circular surface 62a faces the second vertical frame portion 35. More specifically, in the magnet 62, the circular surface 62a faces the sensor unit 70 attached to the second vertical frame portion 35. In the magnet 62, for example, a circular surface 62a having an N pole faces the sensor unit 70. As a result, as shown in FIG. 8, the magnet 62 emits a magnetic force line M toward the sensor unit 70. The magnet 62 may have an S pole facing the sensor unit 70 as long as the sensor unit 70 can detect the magnetic field. Further, the magnet 62 is not limited to a columnar shape, and may be formed into a prismatic shape.

The sensor unit 70 is provided on the frame body 32. Specifically, the sensor unit 70 is provided inside (the back surface side) of the second vertical frame portion 35 facing the door end portion 46 of the shoji 40 in the frame body 32. The sensor unit 70 is screwed to the unit mounting hole 35c of the second vertical plate portion 35. As a result, the sensor unit 70 faces the magnet 62 in the lateral direction. The sensor unit 70 includes a casing 71 and an element 76.

The casing 71 is made of, for example, a resin material. The casing 71 has a cover 72 and a sensor case 73 provided on the back surface of the cover 72. The casing 71 is attached to the second vertical plate portion 35, and the cover 72 covers the unit mounting hole 35c.

The magnetic sensor 75 is provided inside the sensor case 73. In this example, as shown in FIG. 7, two magnetic sensors 75 are provided side by side in a direction perpendicular to the opening / closing direction C (sliding direction) of the shoji 40. These magnetic sensors 75 are held in the sensor case 73 by the case cap 74. The magnetic sensor 75 is, for example, a Hall sensor having an element 76 (Hall element). The magnetic sensor 75 may be an MR sensor having a magnetoresistive effect element.

The element 76 of the magnetic sensor 75 detects the magnetic field of the magnet 62. The magnetic sensor 75 is connected to the control unit 80 by a signal line 78, and transmits the detected magnetic field to the control unit 80. When the shoji 40 is closed, the distance between the magnet 62 and the element 76 is short, so that a large magnetic field is detected. On the other hand, when the shoji 40 is open, the distance between the magnet 62 and the element 76 is long, so that a magnetic field having a small value is detected. The control unit 80 determines whether the shoji 40 is closed or open based on the value of this magnetic field.

Here, a member formed of a magnetic material is not arranged between the element 76 and the magnet 62. As a result, the element 76 does not have the magnetic flux generated from the magnet 62 pulled by another member made of a magnetic material. Therefore, since the magnetic flux that escapes from the element 76 is not generated, the magnetic field can be detected stably.

On the other hand, behind the element 76, a joiner 50 made of a magnetic material is arranged. That is, a joiner 50 made of a magnetic material is provided on the opposite side of the sensor unit 70 from the magnet 62. In other words, the magnet 62, the sensor unit 70, and the joiner 50 are arranged side by side in the lateral direction (opening / closing direction C).

In this case, the joiner 50 is located behind the entire element 76. In other words, when the element 76 is viewed from the front (opening / closing direction C), the entire element 76 overlaps with the joiner 50. As a result, a large amount of magnetic flux generated from the magnet 62 can be directed to the joiner 50, so that the element 76 can stably detect the magnetic field even if the magnetic force of the magnet 62 is weak, for example.

Further, as shown in FIG. 7, the dimension L1 between the joiner 50 and the element 76 is shorter than the dimension L2 between the magnet 62 and the element 76 (L1 <L2). As a result, even if the distance between the magnet 62 and the element 76 is large, the magnetic flux toward the element 76 can be efficiently collected.

Next, the opening / closing determination control of the shoji 40 performed by the control unit 80 will be described.

The control unit 80 controls the operation of the bathroom equipment such as the bathroom air conditioner 10, the bathtub cleaning device 11, and the bathroom cleaning device 12. The control unit 80 may control the operation of equipment in the dressing room such as the dressing room air conditioner 4. The control unit 80 operates the equipment in the bathroom based on the operations of the first remote controller 5, the second remote controller 13, and the third remote controller 15.

Here, if the equipment in the bathroom is operated with the shoji 40 open, the effect of the equipment in the bathroom may not be fully exhibited. For example, when the bathroom air conditioner 10 is operated with the shoji 40 open, the bathroom 6 and the dressing room 1 are in communication with each other, so that the air conditioning of the bathroom 6 may not be sufficiently adjusted. Further, for example, when the bathtub cleaning device 11 or the bathroom cleaning device 12 is operated with the shoji 40 open, the cleaning water may leak from the bathroom 6 to the dressing room 1.

On the other hand, it is desirable that the bathroom equipment is operated in a state where the shoji 40 is completely closed, but it may not cause any trouble even if the shoji 40 is operated in a slightly open state. Since the bathroom door 30 may be provided with a water blocking member (not shown) between the frame 32 and the shoji 40, for example, the bathroom door 30 is substantially closed even if the shoji 40 is not completely closed. It may be in a state.

Assuming that the bathroom equipment cannot be operated unless the shoji 40 is completely closed, for example, when the bathroom equipment is operated by the third remote controller 15 located away from the bathroom 6, the bathroom equipment is operated. Because it cannot be used, it may be inconvenient to use.

Therefore, the control unit 80 determines that the shoji 40 is in the closed state even when it is slightly open. Specifically, the control unit 80 has a magnetic flux density threshold value in a state where the shoji 40 is slightly opened from the fully closed state. This magnetic flux density threshold value is stored (stored) in advance in the storage unit 80a of the control unit 80. The magnetic flux density threshold may be common to all the in-bathroom appliances, or may be individually set for each of the bathroom air conditioner 10, the bathtub cleaning device 11, and the bathroom cleaning device 12. Further, the storage unit 80a stores a processing program for opening / closing determination control performed by the control unit 80.

The magnetic flux density threshold value can be set by experiment or simulation in consideration of, for example, the size of the bathroom 6, the location of the equipment in the bathroom, the performance of the equipment in the bathroom, and the like. For example, the magnetic flux density threshold is a shoji with a minimum permissible range of functional efficiency by comparing the functional efficiency of the equipment in the bathroom when the shoji 40 is fully closed and the functional efficiency when the shoji 40 is open. It can be set based on the position of 40.

In the case of the bathroom air conditioner 10, the heating efficiency when the shoji 40 is fully closed, the heating efficiency when the shoji 40 is slightly opened, and the heating efficiency when the shoji 40 is further opened are measured. Then, the magnetic field of the magnet 62 detected by the magnetic sensor 75 at the position of the shoji 40 when the heating efficiency of the bathroom air conditioner 10 is within the minimum allowable range can be set as the magnetic flux density threshold.

In the case of the bathtub cleaning device 11 and the bathroom cleaning device 12, the cleaning water leaking to the dressing room 1 when the obstacle 40 is slightly opened between the start and end of the operation of the bathtub cleaning device 11 and the bathroom cleaning device 12. The amount and the amount of washing water leaking to the dressing room 1 when the obstacle 40 is further opened are measured. Then, the magnetic field of the magnet 62 detected by the magnetic sensor 75 at the position of the shoji 40 when the amount of washing water leaked to the dressing place 1 is within the minimum allowable range can be set as the magnetic flux density threshold.

The element 76 of the magnetic sensor 75 detects the magnetic field of the magnet 62 provided at the door end portion 46 of the shoji 40. When the shoji 40 is in the fully closed state, the distance between the magnet 62 and the element 76 is the smallest, so that the element 76 detects a magnetic field having a large value. When the shoji 40 is opened from the fully closed state, the magnetic field detected by the element 76 gradually decreases as the distance between the magnet 62 and the element 76 increases. The magnetic sensor 75 transmits the detected magnetic field to the control unit 80.

The control unit 80 determines that the shoji 40 is in the closed state when the magnetic field detected by the element 76 of the magnetic sensor 75 is equal to or higher than the magnetic flux density threshold value. As described above, this closed state includes a slightly open state in addition to the fully closed state. Then, when the control unit 80 determines that the shoji 40 is in the closed state, the control unit 80 permits the operation of the bathroom air conditioner 10, the bathtub cleaning device 11, and the bathroom cleaning device 12. Then, the bathroom air conditioner 10, the bathtub cleaning device 11, and the bathroom cleaning device 12 are operated based on the operations of the first remote controller 5, the second remote controller 13, and the third remote controller 15.

On the other hand, when the control unit 80 determines that the shoji 40 is in the open state, the control unit 80 prohibits the operation of the bathroom air conditioner 10, the bathtub cleaning device 11, and the bathroom cleaning device 12. In this case, the bathroom air conditioner 10, the bathtub cleaning device 11, and the bathroom cleaning device 12 do not operate even if the first remote controller 5, the second remote controller 13, and the third remote controller 15 are operated. As a result, it is possible to suppress the operation of the equipment in the bathroom with the shoji 40 open.

Since the first remote controller 5 is provided in the dressing room 1 and the second remote controller 13 is provided in the bathroom 6, when operating the first remote controller 5 and the second remote controller 13, the user has a shoji screen 40. You can recognize whether it is closed. Therefore, the operation prohibition of the equipment in the bathroom by the open / close determination control of the control unit 80 may be made only to the third remote controller 15 remote from the bathroom 6. That is, when operating the first remote controller 5 in the dressing room 1 or the second remote controller 13 in the bathroom 6 to operate the equipment in the bathroom, the shoji 40 may be open.

Thus, according to the bathroom door unit 20 according to the present embodiment, the frame 32 that forms the entrance / exit 32a between the bathroom 6 and the dressing room 1, the shoji 40 that can be opened and closed with respect to the frame 32, and the open / closed state of the shoji 40. It is provided with an open / close detection unit 60 for detecting the above. The open / close detection unit 60 includes a magnet 62, a casing 71, and a sensor unit 70 having an element 76 provided inside the casing 71 to detect the magnetic field of the magnet 62, and the obstacle 40 has a sensor unit 70. One member of the magnet 62 or the sensor unit 70 is provided, and the frame 32 is provided with the other member of the magnet 62 or the sensor unit 70 facing the one member, and the magnet is sandwiched between the sensor unit 70. A magnetic material is provided on the opposite side of 62.

As a result, the magnetic flux can be attracted from the magnet 62 to the magnetic material via the element 76. Therefore, it is possible to increase the magnetic flux density passing through the element 76 without selecting a material for increasing the magnetic force of the magnet 62 or increasing the size of the magnet 62. As a result, for example, a water blocking material for stopping water is provided between the shoji 40 and the frame 32, and even if the distance between the magnet 62 and the element 76 is large, the open / closed state of the shoji 40 can be detected. It can be detected with high accuracy by 60.

Further, the magnetic material is located behind the entire element 76. As a result, the magnetic flux of the magnet 62 can be effectively collected on the element 76.

Further, the dimension between the magnetic material and the element 76 is shorter than the dimension between the magnet 62 and the element 76. As a result, even if the distance between the magnet 62 and the element 76 is large, the magnetic flux can be gathered to the element 76 by the magnetic material.

Further, the magnet 62 is provided on the door tip portion 46 of the shoji 40, and the sensor unit 70 is provided on the frame body 32. As a result, since the sensor unit 70 is provided on the side of the frame 32 that does not move, the signal line 78 connected to the sensor unit 70 can be easily wired.
