That is, the wind direction louver 12 is rotatable in the vertical direction on the other long side (front side in the drawing) with the one long side (back side in the drawing) as the central axis. Since the stepping motor 11 is provided in the vicinity of the bottom surface of the main body case 3, the wind direction louver 12 is rotated from the central axis to open the air outlet 7 provided on the lower surface of the main body case 3. I.e. open, or closed, i.e. closed. In the open state, the wind direction louver 12 functions as a louver that regulates the upper and lower blowing directions of the circulating airflow blown from the inside of the main body case 3 through the blowout port 7. Further, in the closed state, it functions as a cover that blocks the circulating airflow that blows out from the inside of the main body case 3 through the air outlet 7.

  Further, the wind direction louver 12 is provided with a blocking projection 17 that also serves as a wind direction rectifying plate that adjusts the wind direction in the left and right direction by rectification at the front end portion (front side in FIG. 3) in the blowing direction.

  The blocking protrusion 17 has a plate shape and a plate surface parallel to the blowing direction so as not to be resistant to the blown airflow.

The infrared ray traveling toward the light receiving unit 15 is blocked.

  Further, on the left and right sides of the blocking projection 17, wind direction rectifying plates 18 a, 18 b, 18 c, 18 d, and 18 e that are curved in the left and right end directions toward the front end part so that the blowing air diffuses in the left and right direction from the central part of the wind direction louver 12. , 18f are arranged. The details of the function of each part of the wind direction louver 12 will be described later.

  Next, the configuration of the main body control means 16 will be described with reference to FIG.

  As shown in FIG. 4, the main body control means 16 includes a main body control microcomputer 19, a circulation fan motor drive section 20, a heat exchanger drive section 21, a spray means drive section 22, an infrared light emission drive section 23, An infrared light reception signal input unit 24, a wind direction louver driving unit 25, and a communication unit 26 are provided. In addition, the remote controller 4 includes remote control control means 27.

The circulation fan motor drive unit 20 is connected to the main body control microcomputer 19 and performs drive control of the circulation fan motor 10 based on a signal from the main body control microcomputer 19. The drive control here includes ON / OFF of the power supply, setting / control of the rotational speed of the fan, and the like.
The heat exchanger drive unit 21 is connected to the main body control microcomputer 19 and performs drive control of the heat exchanger 9 based on a signal from the main body control microcomputer 19. The drive control here includes power ON / OFF, heater temperature control, and the like.

  The spraying means drive unit 22 constitutes spraying means for spraying mist together with the electromagnetic valve 13 and is connected to the main body control microcomputer 19 to control the opening / closing and the open / close ratio of the electromagnetic valve 13 based on a signal from the main body control microcomputer 19. To do.

  The infrared light emission drive unit 23 is connected to the main body control microcomputer 19 and performs light emission control of the infrared light emission unit 14 based on a signal from the main body control microcomputer 19. The light emission control here includes ON / OFF of light emission. However, the infrared light emission drive unit 23 may always emit light when energized without being controlled by the main body control microcomputer 19.

  The infrared light receiving signal input unit 24 receives a signal from the infrared light receiving unit 15. That is, when infrared rays from the infrared light emitting unit 14 are received, the fact is notified to the infrared light receiving signal input unit 24 and transmitted to the main body control microcomputer 19.

  The wind direction louver drive unit 25 is connected to the main body control microcomputer 19 and rotates the stepping motor 11 based on a signal from the main body control microcomputer 19. The rotation drive angle can be freely determined within a predetermined range based on a signal from the main body control microcomputer 19, that is, the wind direction louver 12 can be swung or stopped.

  The communication unit 26 controls communication with the remote control control unit 27 and notifies the main body control microcomputer 19 of a signal from the remote control control unit 27.

  Based on information transmitted from the remote control means 27 of the remote controller 4 via the communication cable 5 and the communication unit 26, the main body control microcomputer 19 performs drive control of the circulation fan motor 10, heating control of the heat exchanger 9, Spray control of the electromagnetic valve 13, opening / closing control of the wind direction louver 12, infrared light emission control of the infrared light emitting unit 14, and the like are performed.

  The above is the overall configuration of the bathroom heating dryer 2.

  Next, operation | movement of the bathroom heating dryer 2 is demonstrated, referring FIG.

  When energization of the bathroom heater / dryer 2 is started, the main body control microcomputer 19 starts operating (S1).

  When an operation command for spraying the mist of the bathroom heater / dryer 2 is transmitted from the remote control means 27 to the main body control means 16 (S2), an infrared light emission signal is transmitted from the main body control microcomputer 19 to the infrared light emission drive unit 23, The infrared light emitting unit 14 emits infrared light (S3).

  Then, the presence or absence of infrared light (hereinafter referred to as IR) is detected by the infrared light receiving unit 15 (S4).

  The detected IR information is transmitted to the main body control microcomputer 19 via the infrared light receiving signal input unit 24, and the main body control microcomputer 19 determines the presence or absence of IR (S5).

  Here, when IR is not detected, it can be recognized that the wind direction louver 12 is in a closed state. Then, the main body control microcomputer 19 drives the stepping motor 11 by the wind direction louver driving unit 25 and performs an operation of opening the wind direction louver 12 to a specified opening degree (S6).

  And if it can confirm that IR can be detected (S7), the main body control microcomputer 19 will transmit a drive command to the fan motor drive part 20 for circulation, the heat exchanger drive part 21, and the spray means drive part 22. Thereby, the circulation fan motor 10, the heat exchanger 9, and the electromagnetic valve 13 are driven (S8), and the operation is performed until the stop command for the bathroom heating dryer 2 is transmitted from the remote controller control means 27 (S10 Yes). When the stop command is transmitted, the main body control microcomputer 19 transmits a drive stop command to the circulation fan motor drive unit 20, the heat exchanger drive unit 21, and the spray means drive unit 22, and the circulation fan motor 10 and heat exchange. The device 9 and the electromagnetic valve 13 are stopped driving, and the bathroom heating dryer 2 is stopped (S18).

By the way, it is conceivable that the wind direction louver 12 is closed regardless of a command from the main body control microcomputer 19 while the operation is continued. For example, the user manually closes it. In such a case, there is a possibility that the mist heated by the heater accumulates on the upper surface of the wind direction louver 12 in the closed state and drops from the gap between the wind direction louver 12 and the main body case 3. In such a case, the user may be in contact with a heated water droplet, and in the worst case, there is a possibility of causing a burn.
Assuming such a case, the main body control microcomputer 19 always detects IR similarly to S3, S4, and S5 (S11, S12, and S13) and can detect IR even when the operation is in an open state. If it disappears, it will be in an unexpected state, that is, an abnormal state, and an abnormal report will be issued outside (S17). Further, the failure to detect IR may be a failure or a closed state. If there is a possibility of the closed state, the main body control microcomputer 19 immediately stops the mist spraying and the heater. That is, the bathroom heating / drying machine 2 is stopped simultaneously with the abnormal notification (S18). For example, the abnormal alarm is displayed on the remote controller 4.

  Further, when IR is detected by IR detection at the time of operation command (S5), it is confirmed that the opening and closing of the wind direction louver 12 is normal. That is, the main body control microcomputer 19 drives the stepping motor 11 by the wind direction louver drive unit 25, and closes the wind direction louver 12 with the number of steps equal to or greater than the fully opened degree of opening (S19).

  Then, the infrared light emitting unit 14 emits IR (S20), and the infrared light receiving unit 15 detects IR (S21).

  The detected IR information is transmitted to the main body control microcomputer 19 via the infrared light reception signal input unit 24, and the main body control microcomputer 19 determines the presence or absence of IR (S22).

  If IR is not detected, it is determined that the wind direction louver 12 is in a closed state and is operating normally, and the main body control microcomputer 19 drives the stepping motor 11 by the wind direction louver driving unit 25 to designate the wind direction louver 12. The operation is performed up to the opening (S6).

  If IR is detected, the operation of the wind direction louver 12 is regarded as abnormal, and an abnormality is reported to the outside (S17). Then, the bathroom heater / dryer 2 is stopped (S18).

  As described above, the bathroom heater / dryer according to the present embodiment determines the open / closed state of the wind direction louver by the blocking protrusion that also serves as the wind direction control plate.

  That is, since the blocking protrusion can be configured in a small and integrated manner in, for example, forming the shape of the wind direction louver, it is possible to suppress water accumulation and prevent dripping due to blowing. In addition, since there is no gap due to the configuration, dust such as moisture and dust remains in the gap, and mold and bacteria do not propagate. In addition, it is possible to prevent the detection of the opening degree of the wind direction louver due to the wrong polarity when attaching the magnet or forgetting to attach it.

  Further, by providing the blocking projection at the center in the left-right direction, even when water droplets are generated, dripping from the side of the wind direction louver can be prevented.

  Further, by providing at the front end in the blowing direction, even when water droplets are generated during operation, it can be scattered from the front end while the water droplet size is very small due to the blowing air, and discomfort caused by dripping can be suppressed.

  In addition, since the blocking projection can also serve as the wind direction rectifying plate, no magnet mounting part is required, and when adopting a configuration that obtains a rectifying action, it is necessary to provide the blocking projection only to detect the opening and closing of the wind direction louver There is no.

  In addition to the presence / absence determination of infrared rays, the confirmation process is performed, so that mist is sprayed with the wind direction louver closed and water drops in a high temperature state, preventing accidents such as burns caused by dripping. it can.

As mentioned above, in this Embodiment 1, although the bathroom heating dryer 2 and the remote controller 4 were set as the structure connected by the communication cable 5, as long as the bathroom heating dryer 2 and the remote controller 4 can communicate,
Wireless communication using radio waves or infrared rays without using a communication cable may be used.

  Further, although the abnormal report is displayed on the remote controller 4, it may be reported using voice.

  Moreover, the arrangement | positioning position does not have a restriction | limiting, what is necessary is just to arrange | position so that the infrared rays light-receiving part 15 may not receive the infrared rays which the infrared rays light emission part 14 light-emits in the state where the wind direction louver 12 is closed.

  As described above, the bathroom heater / dryer of the present invention does not require a magnet, an accident such as a burn due to incorrect detection of a magnet, an undetected wind direction louver open / closed state due to forgetting to install, and a mold caused by a puddle of water, It is possible to prevent the propagation of various bacteria. Therefore, for example, it is expected to be utilized for sauna devices, humidifiers, plant growing facilities that are affected by the growth of fungi and germs, and the like that require prevention of accidents such as burns.
