Description

  The present invention relates to a far-infrared irradiation apparatus that irradiates far-infrared rays to dry a floor surface and a washstand of a collective toilet and heat the collective toilet.

  In facilities used by a large number of people, such as highway service areas, parking areas, stations, movie theaters, and halls, collective toilets equipped with a plurality of washstands and toilets are installed (for example, see Patent Document 1). ).

  In such a collective toilet, a hot air dryer or a heating appliance is often installed near the washstand recently (for example, see Patent Documents 2 and 3).

JP 2008-202288 A JP 2008-61732 A JP 2010-16428 A

  While the user of the collective toilet is washing his hands and face with the wash basin, water droplets may fly around. Immediately after the user has washed his / her hand in the washbasin or while moving to the location where the hot air dryer is installed, the user may shake his / her wet hand and the water droplet may fly or the water drop may drip from the wet hand. When it rains or snows, the user may enter the collective toilet with the shoe soles wet. In addition, cleaning staff may sprinkle water on the floor to perform cleaning.

  In such a case, the upper surface and the floor surface of the washstand become wet and this state continues for a while, which may cause a problem in terms of safety and hygiene.

  Moreover, the heater installed in the collective toilet is used only in winter when the temperature is below a certain temperature, and there is a problem that the operation rate is low.

  Then, an object of this invention is to provide the far-infrared irradiation apparatus which can dry the wet floor surface of a collective toilet, and the upper surface of a washstand in a short time, and has a high operation rate.

  The far-infrared irradiation device of the present invention includes a traveling rail, a heater unit, a drive unit, an operation unit, and a control unit. The heater unit includes a far-infrared generator and a reflector. The drive unit includes an elevating part and a traveling part. The traveling rail is installed horizontally in the collective toilet. In the far infrared ray generator, when the operation unit receives the operation mode of the apparatus main body, the control unit controls the heater unit and the drive unit according to the operation mode received by the operation unit. The operation mode includes, for example, a drying mode and a heating mode. When the controller receives the drying mode from the operation unit, the controller emits far infrared rays from the far infrared generator of the heater unit, and lowers the heater unit to the vicinity of the floor surface or the upper surface of the washstand by the lifting unit of the drive unit. The heater unit is moved along the traveling rail by the traveling unit. Thereby, since a far infrared ray can be irradiated to the floor surface of a collective toilet, the wet floor surface and the upper surface of a washstand can be dried in a short time.

  In addition, when the operation unit receives the heating mode, the control unit emits far infrared rays from the far infrared generator of the heater unit, raises the heater unit to the vicinity of the ceiling by the lifting unit of the drive unit, and causes the traveling unit to The heater unit is moved to a predetermined position, for example, the upper part of the washstand, and the movement of the heater unit is stopped. Thereby, since a far infrared ray can be irradiated to the washstand of the collective toilet, the user of the washstand can be warmed.

  The far-infrared irradiation device includes a moisture detection unit. The control unit controls the heater unit and the drive unit according to the moisture detection result on the detection target surface such as the floor surface of the collective toilet or the upper surface of the washstand detected by the moisture detection unit. For example, if the moisture detection unit detects moisture on the floor or the top of the washstand during drying by receiving a drying mode and irradiating the top surface of the floor or washstand with far infrared rays, It is moved along the movement route, and the floor surface and the upper surface of the washstand are subsequently dried. On the other hand, when the moisture detector no longer detects moisture on the floor surface or the top surface of the wash basin, the floor surface or top surface of the wash basin is dry. Raise and move to home position. Thereby, when the floor surface or the upper surface of the washstand is dried, the heater unit can be automatically moved to the home position 6.

  The heater unit of the far infrared irradiation device includes a fan. When the control unit accepts the drying mode by the operation unit, the control unit causes the far-infrared generator to emit far-infrared rays, and further causes the fan to blow in a direction in which the reflection plate reflects far-infrared rays.

  Thereby, since far-infrared rays are irradiated to the floor surface and the upper surface of the washstand and wind is blown, the floor surface and the upper surface of the washstand can be dried in a shorter time.

  The heater unit of the far-infrared irradiation device detects a certain range of users by the human detection unit. When the human detection unit detects a user after the operation unit accepts the drying mode, the control unit moves or raises the heater unit to the drive unit until the human detection unit no longer detects the user.

  As a result, even when the user approaches the heater unit while the floor surface of the collective toilet or the upper surface of the wash basin is being dried by the heater unit, the heater unit does not collide with the user, and the floor surface or the wash basin The top surface can be safely dried.

  When the operation unit receives the follow-up heating mode input and the human detection unit detects the user, the control unit of the far-infrared irradiation device causes the travel unit to travel on the travel rail to follow the user.

  Thus, while the user is in the collective toilet, the user can be irradiated with far-infrared rays, so that the user can be prevented from feeling cold.

  The far-infrared irradiation device includes a pair of auxiliary rails installed orthogonal to the traveling rails, and an auxiliary traveling unit that is installed on the traveling rails and travels along the pair of auxiliary rails.

  In this configuration, the heater unit can be moved not only in the direction along the traveling rail but also in the direction along the auxiliary rail. Thereby, since the movable range of a heater unit spreads, it becomes possible to dry the whole inside of a collective toilet, such as a floor surface and the upper surface of a washstand.

  According to the present invention, the far-infrared irradiation device can dry the wet floor of the collective toilet and the upper surface of the washstand in a short time, and since the far-infrared irradiation device can be used as a drying device and a heating device, The operating rate of the apparatus can be increased.

The detailed configuration of the heater unit 4 will be described later.

  The auxiliary traveling unit 5L and the auxiliary traveling unit 5R are shown in FIG. 1B, along the auxiliary rails 6L and 6R, the traveling rail 2, the drive unit 3 and the heater unit 4 attached to the traveling rail 2. Move in the Y direction (front-rear direction in FIG. 1A). The auxiliary traveling unit 5L is connected to one end of the traveling rail 2 by a housing 511L. The auxiliary traveling unit 5R is connected to the other end of the traveling rail 2 by a housing 511R.

  The auxiliary rails 6L and 6R are tracks for the auxiliary traveling unit 5L and the auxiliary traveling unit 5R to move in the Y direction shown in FIG. The auxiliary rails 6 </ b> L and 6 </ b> R are made of a steel material having a U-shaped cross section, and are horizontally installed near the ceiling of the collective toilet where the far-infrared irradiation device 1 is installed. Further, the auxiliary rails 6L and 6R are installed orthogonal to the traveling rail 2.

  The auxiliary traveling unit 5L includes an auxiliary traveling unit 51L (not shown in FIG. 1). The auxiliary traveling unit 51L includes a motor 512L, wheels 513L and 514L, and a gear (not shown).

  In the vicinity of the auxiliary rails 6L and 6R, there are provided electric wires (not shown) for supplying electric power to the auxiliary traveling unit 5L and the auxiliary traveling unit 5R, respectively.

  In the auxiliary traveling unit 5L, the wheel 513L is driven by a motor 512L via a gear (not shown). Similarly, in the auxiliary traveling unit 5R, the wheel 513R is driven by a motor 512R via a gear (not shown). At this time, the auxiliary traveling unit 5L and the auxiliary traveling unit 5R travel on the auxiliary rails 6L and 6R in the Y direction by the wheels 513L, 514L, 513R, and 514R. As a result, the drive unit 3 and the heater unit 4 move in the Y direction. The auxiliary traveling unit 5L and the auxiliary traveling unit 5R are driven to travel in the same direction at the same timing.

  As shown in FIGS. 1A to 1C, the bottom surface 3T of the drive unit 3 is inclined with respect to the horizontal plane. That is, it is inclined with respect to the upper surface 4J and the bottom surface 4T of the heater unit 4 suspended from the heater unit 4 at a predetermined distance.

  As shown in FIGS. 2A and 2B, when the wire 322 is wound up by the winch 321 of the elevating unit 32, the upper surface 4J of the heater unit 4 and the bottom surface 3T of the drive unit 3 are in contact with each other in parallel. become. As a result, the bottom surface 4T of the heater unit 4 is parallel to the bottom surface 3T of the drive unit 3 and is held by the drive unit 3 in an inclined state with respect to the horizontal plane. Therefore, in the state where the heater unit 4 is wound up, far infrared rays can be irradiated obliquely downward. At this time, the bottom surface 4T of the heater unit 4 is installed so as to have a height that does not hit the user of the collective toilet (for example, a height of 2 m or more from the floor surface).

  The configuration of the heater unit 4 is as follows. As shown in FIGS. 3A to 3C, the heater unit 4 includes a housing 42, a far-infrared generator 43, a reflector 44, a side reflector 45, a side reflector 46, a partition reflector 47, A protective net 48 and a heat insulating material 49 are provided. In addition, the heater unit 4 is provided with a moisture detection sensor 51 that is a moisture detection unit, human detection sensors 52A to 52D that are human detection units, and a temperature sensor 53 that is a temperature detection unit outside the housing 42. . A warning lamp 541 and a speaker 542 are attached to the upper surface 4J of the heater unit 4.

  The casing 42 has a trapezoidal cross section in the longitudinal direction, and an opening 42K corresponding to the bottom surface is opened. A tubular (bar-shaped) far-infrared generator 43 is provided inside the housing 42. Far-infrared rays radiated from the far-infrared generator 43 are reflected by the reflecting plate 44, the side reflecting plate 45, the side reflecting plate 46, and the partition reflecting plate 47 installed inside the housing 42, and are emitted from the radiating unit. Is done. Each reflector is made of a metal such as aluminum or a metal film such as aluminum on a material such as aluminum or plastic. These reflectors are preferably processed so as to increase the reflectivity of far-infrared rays by performing chemical treatment, electrolytic treatment, or mechanical polishing.

  The reflector 44 is bent with a predetermined curvature, reflects the far infrared rays emitted from the far infrared generator 43 and irradiates a certain region from the opening of the heater unit 4. For example, when bending is performed as shown in FIG. 3, the far-infrared irradiation angle can be limited to within 20 ° with respect to the longitudinal direction (vertical direction) of the heater unit 4. Note that the curvature of the reflecting plate 44 varies depending on the size of the heater unit 4 and the size of the region irradiated with far-infrared rays, and thus may be obtained by calculation or experiment.

  The side reflector 45, the side reflector 46, and the partition reflector 47 reflect the far infrared rays emitted from the far infrared generator 43, and according to the inclination angle that sets the far infrared irradiation region in the longitudinal direction of the heater unit 4. Limit. For example, as shown in FIG. 3, a partition reflecting plate 47 is provided in addition to the side reflecting plate 45 and the side reflecting plate 46, and each reflecting plate is 20 ° with respect to the longitudinal direction (vertical direction) of the heater unit 4. By setting it as an inclined surface, the radiation angle of far-infrared rays can be limited within 30 ° with respect to the longitudinal direction (vertical direction) of the heater unit 4.

  The radiating portion 42K of the housing 42 is provided with a lattice-shaped protective net 48 to prevent a person from touching a portion heated when the far-infrared generator 43 is energized, such as the far-infrared generator 43 and the reflector 44. ing. A heat insulating material 49 is attached between the housing 42 and each reflector.

  The far-infrared generator 43 has a halogen lamp coated with black far-infrared radiation ceramics. In a halogen lamp, a filament made of tungsten is disposed at a substantially central portion in a bulb made of quartz glass, and a halogen gas and an inert gas such as argon or nitrogen are enclosed. The halogen lamp has the following characteristics.

  The filament of the halogen lamp has a small heat capacity and can raise the temperature at a speed several times higher than other far infrared heaters such as ceramic heaters and infrared heaters equipped with nichrome wire coils.

  75 to 95% of the input power is converted into light and heat, of which 6 to 12% is visible light and heat, and the rest is infrared, and energy efficiency is high.

  The far-infrared radiation ceramics coated on the halogen lamp generates heat by absorbing visible light and near-infrared radiation emitted from the halogen lamp, and emits far-infrared radiation having a peak in a wavelength region of 2.5 μm to 15 μm. For example, far infrared rays having peak values of about 3 μm and about 6 μm are emitted. Further, wavelengths of far infrared rays suitable for heating and evaporating water are about 3 μm and about 10 μm. The far-infrared radiation emitted by the far-infrared generator 43 has a peak value at about 3 μm and about 6 μm as described above, and thus the radiance of far-infrared rays of about 3 μm and about 10 μm is high. Accordingly, it is possible to efficiently dry the heating and floor surface by irradiating a large amount of far infrared rays having a wavelength suitable for heating and evaporating water. Further, since the heat capacity is small like the filament of the halogen lamp, the temperature can be raised in a short time.

  The far-infrared ray irradiation device 1 detects moisture such as the floor surface of the collective toilet or the upper surface of the wash basin, which is the detection target surface, by the moisture detection sensor 51, and determines whether the floor surface or the upper surface of the wash basin is dry. Check. For example, the moisture detection sensor 51 outputs a light beam to the floor surface of the collective toilet, and detects moisture on the floor surface based on the reflectance.

  Further, the far-infrared irradiation device 1 detects the approach or passage of the user to the heater unit 4 by the human detection sensors 52A to 52D. For example, the human detection sensors 52A to 52D output a light beam to the surroundings and detect the user based on the presence or absence of reflection of the light beam. The human detection sensors 52A to 52D detect a person whose distance from the center of the heater unit 4 is within a certain range (for example, 1.5 m).

  Further, the far-infrared irradiation device 1 measures the ambient air temperature with the temperature sensor 53.

  Next, the heater unit 4 may be configured to include a fan. The heater unit 4 shown in FIG. 4 includes fans 711F to 714F, fans 711B to 714B, movable mechanisms 721F and 722F, and movable mechanisms 721B and 722B in addition to the configuration shown in FIG.

The fans 711F to 714F are arranged along the longitudinal direction of the radiating portion 42K and are connected to the movable mechanisms 721F and 722F. The movable mechanisms 721F and 722F have a built-in motor, and switch the fans 711F to 714F from the folded state to the unfolded state or from the unfolded state to the folded state.

  Similarly, the fans 711B to 714B are arranged along the longitudinal direction of the radiating portion 42K and are connected to the movable mechanisms 721B and 722B. The movable mechanisms 721B and 722B have a built-in motor, and switch the fans 711B to 714B from the folded state to the expanded state or from the expanded state to the folded state.

  Next, a control system of the far infrared irradiation device 1 will be described. In the following description, the heater unit 4 is configured to include the plurality of fans shown in FIG.

  As shown in FIG. 5, in the far infrared irradiation device 1, the drive unit 3 includes a traveling unit 31, an elevating unit 32, an internal communication unit 33, an external communication unit 34, and a control unit 35.

  The heater unit 4 includes a moisture detection sensor 51, human detection sensors 52 </ b> A to 52 </ b> D, a temperature sensor 53, a notification unit 54, a blower unit 71, a movable unit 72, an internal communication unit 41, and a far infrared generator 43. The notification unit 54 includes a warning light 541 and a speaker 542. The air blower 71 includes fans 711F to 714F and fans 711B to 714B. The movable part 72 includes movable mechanisms 721F and 722F and movable mechanisms 721B and 722B.

  The auxiliary traveling unit 5L includes an auxiliary traveling unit 51L and an internal communication unit 52L. The auxiliary traveling unit 5R includes an auxiliary traveling unit 51R and an internal communication unit 52R.

The control unit 35 controls the heater unit 4 and the auxiliary traveling units 5L and 5R via the internal communication unit 33.

  Next, an installation example of the far infrared irradiation device 1 will be described. FIG. 6A shows a case where the far-infrared irradiation device 1 is provided in a large bathroom 10. FIG. 6B shows a case where the far infrared irradiation device 1 ′ is provided in the collective toilet 15 that is smaller than the collective toilet 10.

  As shown in FIG. 6A, the collective toilet 10 has a rectangular parallelepiped shape, and the wall 10N and the wall 10S, and the wall 10E and the wall 10W face each other. In the collective toilet 10, a plurality of urinals 11S, a plurality of washstands 11W, and a plurality of booths 11B in which urinals are installed are installed across two passages 10A and 10B. The auxiliary rail 6L of the far infrared irradiation device 1 is installed in the vicinity of the ceiling 10T of the collective toilet 10 along the wall 10E. The auxiliary rail 6R is installed in the vicinity of the ceiling 10T of the collective toilet 10 along the wall 10W. The traveling rail 2 is installed in parallel with the wall 10N and the wall 10S. Moreover, the traveling rail 2, the auxiliary rail 6L, and the auxiliary rail 6R are installed horizontally.

  By installing the far-infrared irradiation device 1 as described above, the heater unit 4 is moved in the three directions of the collective toilet 10 in the left-right direction (X direction), the front-rear direction (Y direction), and the up-down direction (Z direction). be able to. 6A adjusts the lengths of the auxiliary rails 6L and 6R so that the heater unit 4 does not move to the installation area of the booth 11B of the collective toilet 10.

  Next, as shown in FIG. 6B, the collective toilet 15 has a rectangular parallelepiped shape, and the wall 15N and the wall 15S, and the wall 15E and the wall 15W face each other. The collective toilet 15 is narrower than the collective toilet 10, and a plurality of urinals 11S and a plurality of wash basins 11W and a plurality of booths 11B in which urinals are installed are installed across one passage 15A. Thus, it is only necessary to move the heater unit 4 in two directions, ie, the left and right direction (X direction) and the up and down direction (Z direction) of the collective toilet 15 with one passage. In such a case, a far-infrared irradiation device 1 ′ that can move the heater unit 4 in two directions may be installed. That is, the far-infrared irradiation device 1 'is obtained by deleting the auxiliary traveling unit 5L, the auxiliary traveling unit 5R, the auxiliary rail 6L, and the auxiliary rail 6R of the far-infrared irradiation device 1. The far-infrared irradiation device 1 ′ operates in the same manner as the far-infrared irradiation device 1 except that the moving direction is one direction less.

  Next, the operation when the far infrared irradiation device 1 is provided in the collective toilet 10 will be described.

  In the far-infrared irradiation device 1, any one of a drying mode, a heating mode, and a follow-up heating mode can be set. The operator can change or select the operation mode by operating the remote controller 7.

  The home position of the heater unit 4 of the far-infrared irradiation device 1 is the upper part of the washstand 11W as shown in FIG. 6A, and the wire 322 is wound up by the winch 321 as shown in FIG. is there. When the heating mode is set, the heater unit 4 is located at the home position.

  As shown in FIG. 7, the control unit 35 of the far-infrared irradiation device 1 operates until the operation mode setting signal transmitted from the remote controller 7 is received by the external communication unit 34 (S1: N). (S2).

  When the external communication unit 34 receives the operation mode setting signal transmitted from the remote controller 7 (S1: Y), the control unit 35 of the far infrared irradiation device 1 performs the operation mode processing according to the setting signal.

  When performing the heating mode (S3: Y), the control unit 35 performs the processing after step S10.

  Control part 35 performs processing after Step S20 shown in Drawing 8 (A), when performing follow-up heating mode (S3: N, S4: Y).

  When performing the drying mode (S3: N, S4: N, S5: Y), the control unit 35 performs the processing after step S31 shown in FIG.

  When the heating mode is started (S3: Y), the control unit 35 first moves the heater unit 4 to the home position if it is not in the home position (S10). When the control unit 35 moves the heater unit 4 to the home position, the control unit 35 transmits a control signal to the internal communication units 52L and 52R via the internal communication unit 33 to drive the auxiliary travel units 51L and 51R to travel. The rail 2 is moved. The control unit 35 outputs a control signal to the traveling unit 31 to move the drive unit 3 and the heater unit 4. Further, the control unit 35 outputs a control signal to the elevating unit 32 to raise the heater unit 4.

  Subsequently, the control unit 35 measures the ambient air temperature with the temperature sensor 53 (S11). If the temperature measured by the temperature sensor 53 exceeds 10 degrees (S12: Y), the control unit 35 stops the far-infrared generator 43 if the far-infrared generator 43 is in operation (S13), and the step The process after S11 is performed.

  When the temperature sensor 53 measures the temperature, the temperature sensor 53 outputs temperature information to the control unit 35 via the internal communication unit 41 and the internal communication unit 33. Further, the control unit 35 outputs an on / off control signal to the far-infrared generator 43 via the internal communication unit 33 and the internal communication unit 41.

  On the other hand, if the temperature measured by the temperature sensor 53 is not less than 5 degrees and not more than 10 degrees (S12: N, S14: Y), the control unit 35 causes the human detection sensors 52A to 52D to move within a certain range from the heater unit 4. When a user is detected (S15: Y), the far-infrared generator 43 is turned on to irradiate the user with far-infrared rays (S16). Thereby, since far infrared rays hit a user, a user can feel warmth.

  The human detection sensors 52 </ b> A to 52 </ b> D output a signal corresponding to the detection result of the user to the control unit 35 via the internal communication unit 41 and the internal communication unit 33.

  The control unit 35 turns on the far infrared ray generator 43 to irradiate the user with far infrared rays (S16) until the human detection sensors 52A to 52D do not detect the user (S17: N).

  When the human detection sensors 52A to 52D do not detect the user (S17: Y), the control unit 35 turns off the far-infrared generator 43 and stops the emission of far-infrared (S18), and the processing after step S11. I do.

  Moreover, if the temperature measured with the temperature sensor 53 is less than 5 degree | times (S12: N, S14: N), the control part 35 will always turn on the far infrared ray generator 43, and will irradiate a far infrared ray (S19). . At this time, the washstand 11W and the wall 10N around the washstand 11W are warmed by far infrared rays, and heat is released from the washstand 11W and the wall 10N. Therefore, the user can feel warmth by the far infrared rays hitting the user and the heat radiated from the washstand 11W and the wall 10N.

  When the far-infrared generator 43 is always turned on in step S19, the control unit 35 measures the temperature and monitors the fluctuation of the temperature (S11), and performs the above processing according to the temperature.

  Next, when the follower heating mode is started (S4: Y), the control unit 35 first moves the heater unit 4 to the home position unless the heater unit 4 is located at the home position, as shown in FIG. 8A. (S20).

  Subsequently, the control unit 35 measures the ambient temperature with the temperature sensor 53 (S21). If the temperature measured by the temperature sensor 53 exceeds 10 degrees (S22: Y), the control unit 35 stops the far-infrared generator 43 if the far-infrared generator 43 is operating (S23), and the step The process after S21 is performed.

  On the other hand, when the temperature measured by the temperature sensor 53 is 10 degrees or less (S22: N), the control unit 35 detects a user within a certain range from the heater unit 4 by the human detection sensors 52A to 52D. (S24: Y), the far infrared ray generator 43 is turned on, and the user is irradiated with far infrared rays (S25). Further, the control unit 35 causes the heater unit 4 to follow this user (S26). That is, the control unit 35 operates the traveling unit 31 and the auxiliary traveling units 51L and 51R to move the heater unit 4 together with the user so that the human detection sensors 52A to 52D continuously detect the user. Thereby, since far-infrared rays always hit this user, a user can always feel warmth.

  The control unit 35 continues the processing of steps S24 to S26 until the user cannot be detected by the human detection sensors 52A to 52D.

  If the user cannot be detected by the human detection sensors 52A to 52D (S24: N), the control unit 35 performs the processing from step S20.

  Next, when the drying mode is started (S5: Y), the controller 35 first lowers the heater unit 4 by the elevating unit 32 as shown in FIG. 8B (S31). For example, the control unit 35 lowers the heater unit 4 until the height of the radiation unit 42K (bottom surface 4T) of the heater unit 4 reaches 1.0 m from the top surface of the floor surface 10Y or the washstand 11W. The control unit 35 outputs a control signal to the elevating unit 32 to lower the heater unit 4. Further, the far-infrared irradiation device 1 moves the heater unit 4 up and down while detecting the height from the upper surface of the floor surface 10Y and the washstand 11W with a sensor (not shown) provided in the heater unit 4.

  Subsequently, the control unit 35 turns on the far-infrared generator 43 and irradiates far-infrared rays on the floor surface 10Y and the upper surface of the washstand 11W (S32). In addition, the control unit 35 causes the heater unit 4 to move at a constant speed along a predetermined route by the traveling unit 31 and the auxiliary traveling units 51L and 51R (S33).

  For example, the control unit 35 moves the heater unit 4 along the route K1 shown in FIG. Further, in the case of the far-infrared irradiation device 1 ′, the heater unit 4 is moved along the route K 2 as shown in FIG. 9B. The far-infrared irradiation device 1 detects a traveling position on the traveling rail 2 and the auxiliary rails 6L and 6R with a sensor (not shown) provided on the driving unit 3 and the auxiliary traveling units 6L and 6R, and sets the normal route. Run.

  While the heater unit 4 is moving, the control unit 35 blinks the warning lamp 541 to warn surrounding workers and users that the heater unit 4 is moving. The control unit 35 may emit a warning sound or a warning message from the speaker 542 while the heater unit 4 is moving.

  In the drying mode, the control unit 35 detects people approaching the heater unit 4 using the human detection sensors 52A to 52D. This is to prevent the user from colliding with the heater unit 4 during execution of the drying mode. When the user is detected by any of the human detection sensors 52A to 52D (S34: Y), the control unit 35 starts measuring a certain time (for example, 5 seconds) with a timer (not shown). Then, the control unit 35 notifies the user from the speaker 542 until the predetermined time elapses, so that the user is warned to leave the heater unit 4 because it is dangerous (S35, S36: N). At this time, the control unit 35 may stop the movement of the heater unit 4.

  If the control unit 35 continues to detect the user with any of the human detection sensors 52A to 52D (S37: Y) even after a predetermined time has elapsed, the controller 35 causes the elevator unit 32 to hit the user with the heater unit 4. The height is raised to a certain height (for example, 2 m) (S38). At this time, the control unit 35 notifies the speaker 542 of a warning that the heater unit 4 is raised because it is dangerous. And the control part 35 waits in the position raised until it stops detecting a user with the human detection sensors 52A-52D.

  When the user moves and none of the human detection sensors 52A to 52D detects the user (S37: N), the controller 35 lowers the heater unit 4 by the elevating unit 32 and moves the heater unit 4. Is started (S39).

  Note that when the user is detected by any of the human detection sensors 52A to 52D, the control unit 35 moves the heater unit 4 using the traveling unit 31 and the auxiliary traveling units 51L and 51R until the user is not detected. It is also possible to make it.

  If the movement of the heater unit 4 is started in step S39 or if the user is not detected by the human detection sensors 52A to 52D in step S34 (S34: N), the control unit 35 performs the process of step S40.

  In the drying mode, the control unit 35 detects moisture on the floor surface 10Y of the collective toilet 10 and the upper surface of the wash basin 11W by the moisture detection sensor 51 in step S40. This is to confirm whether the floor surface 10Y of the collective toilet 10 and the upper surface of the washstand 11W are wet or dry. The moisture detection sensor 51 outputs the moisture detection result to the control unit 35 via the internal communication unit 41 and the internal communication unit 33.

  When the detection result of the moisture detection sensor 51 is equal to or greater than a preset threshold value, that is, when the floor surface 10Y is wet (S40: Y), the control unit 35 performs the processing after step S33. That is, the control unit 35 continuously irradiates the floor surface 10Y with far infrared rays from the far infrared ray generator 43 while moving the heater unit 4 at a constant speed.

  It is also possible to set the air blowing unit 71 to operate at the same time so as to blow air to the floor surface 10Y. By doing in this way, the floor surface 10Y of the collective toilet 10 and the upper surface of the wash basin 11W can be further dried in a short time by far infrared rays and wind.

  On the other hand, when the detection result of the moisture detection sensor 51 is less than a preset threshold value, that is, when the upper surface of the floor surface 10Y or the washstand 11W is dry (S40: N), the control unit 35 is a traveling unit. 31, by increasing the moving speed of the auxiliary travel parts 51L, 51R, up to a place where the detection result of the moisture detection sensor 51 is equal to or greater than a preset threshold, that is, to a place where the floor surface 10Y or the top surface of the wash basin 11W is wet. The heater unit 4 is moved at a high speed (S41).

  If the control unit 35 does not dry the upper surface of the floor surface 10Y and the wash basin 11W in all the regular routes (S42: N), and there is a place wet on the upper surface of the floor surface 10Y and the wash basin 11W (S40: Y). ), The processing after step S33 is performed.

  As a result of moving the heater unit 4, the control unit 35 turns off the far-infrared generator 43 when the floor surface 10Y and the upper surface of the wash basin 11W are dry in all routes (S42: Y). Irradiation of far-infrared rays to the upper surface of 10Y and the washstand 11W is stopped. Further, when the air blowing unit 71 is operated, the air blowing unit 71 is stopped and the air blowing unit 71 is folded by the movable unit 72. Further, the control unit 35 turns off the warning lamp 541 (S43). And the control part 35 raises the heater unit 4 by the raising / lowering part 32, and moves the heater unit 4 to a home position by the traveling part 31 (S44).

  Thus, since the far-infrared irradiation apparatus 1 irradiates far-infrared rays on the floor surface 10Y of the collective toilet 10 and the upper surface of the washstand 11W, the water on the upper surface of the floor surface 10Y and the washstand 11W is evaporated in a short time. Can be dried.

  The heater unit 4 of the far-infrared irradiation device 1 ′ has a configuration in which the elevating unit 32 winds up the wire 322 and performs rewinding to raise and lower the heater unit 4. . For example, auxiliary rails are provided at both ends of the traveling rail 2 in the direction of the ceiling and floor of the collective toilet. In addition, auxiliary drive units are provided at both ends of the traveling rail 2. The auxiliary drive unit is configured to move up and down the auxiliary rail. Thereby, the traveling rail 2, the drive unit 3, and the heater unit 4 can be moved up and down between the ceiling and the floor of the collective toilet along the auxiliary rail.

  In this case, the heater unit 4 may be provided with a mechanism that changes the orientation of the heater unit 4 with respect to the drive unit 3. Thereby, the direction of the heater unit 4 can be changed between the heating mode and the drying mode. Further, even in the drying mode, by changing the direction of the heater unit 4 periodically, the irradiation range of the far infrared rays can be expanded, and a wide range can be dried.

  In addition, when air temperature becomes more than predetermined temperature (for example, 25 degree | times) in summer etc., the ventilation part 71 provided in the heater unit 4 is operated, and it replaces with heating mode or tracking heating mode, and ventilation mode or tracking ventilation mode is changed. It can also be configured to run and hit the user. Thereby, a user can feel cool and the operating rate of the far-infrared irradiation device 1 can be further improved.
