Embodiment 1
First, the configuration of the bathroom fan 1 will be described with reference to FIG. FIG. 1 is a schematic view showing the structure of a bathroom air blower 1. As shown in FIG. As shown in FIG. 1, the bathroom air blower 1 is installed on the ceiling of the bathroom and includes an air blower 2, a housing 3, a panel 4, and an operation panel 5.

  The blower unit 2 includes an inlet 2a, an outlet 2b, an air passage 2c connecting the inlet 2a and the outlet 2b, a fan 2d in the air passage 2c, and a motor (motor is not shown) for moving the fan 2d. ing. The outlet 2b is in the form of a slit extending in a direction parallel to the side wall 8 that strikes the back of the user 7 during bathing, and is provided close to the side wall 8.

  The operation panel 5 can control the operation of the bathroom fan 1, the amount of air blown, and the direction of air blown. The operation panel 5 electrically transmits a signal to the control unit of the blower unit 2 of the bathroom blower 1 to perform operation control of the bathroom blower 1 and control of the air blowing amount and the air blowing direction.

  The operation panel 5 is provided with a switch for the user to instruct the start and end of the air blowing. Generally, it is assumed that the user 7 instructs the start of air blowing in the bath 6 after washing the body in the washing place, so the operation panel 5 is in particular in the bathroom from the bath 6 to the user 7 It is desirable to arrange within the reach of

  Next, the operation of the bathroom fan 1 will be described with reference to FIGS. 1 and 2. FIG. 2 is a schematic top view of the positional relationship between the bathroom air blower 1 and the outlet 2b and the user 7 in the bath in the bath 6 as viewed from a ceiling surface.

  The operation of the bathroom fan 1 is such that when the user 7 operates the operation panel 5, the blower unit 2 is operated and the air is blown toward the user 7. The blower 2 sucks the air in the bathroom from the suction port 2a, and the air flow blown out from the fan 2d is blown out from the blowout port 2b into the bathroom again.

  The panel 4 of the bathroom fan 1 has a flat plate shape, and is rectangular in plan view. The suction port 2a and the blowout port 2b are provided so as to be opposed to each other at positions approaching the pair of opposing short sides of the panel 4, respectively. The inlet 2 a and the outlet 2 b are formed in the panel 4 with a predetermined distance (15 cm or more).

  At this time, the position and the blowing air direction of the blowing outlet 2b are set so that the wind blown from the blowing outlet 2b is blown to the lower bath 6 along the side wall 8 corresponding to the back face of the user 7 while bathing. I assume. By setting in this manner, as shown in FIG. 1, the wind blown out from the outlet 2 b descends along the side wall 8, and the air flow strikes a range centered on the back of the user 7 during bathing. The range mainly affected by the air flow is the range 9 indicated by a gray circle in FIG.

  As described above, since the air flow blown out from the outlet 2b of the bathroom fan 1 mainly strikes the top or back side of the user 7 during bathing, that is, the top of the head, the back of the head, the neck and the shoulder, While giving a refreshing sensation due to the cooling effect, the user 7 does not have the discomfort that the air flow hits the user's face from the front.

  Furthermore, the wind volume and the wind speed are reduced by the synergistic effect of not being blocked by the Coanda effect generated by the wind blown out from the outlet 2b along the side wall 8 and the rising air flow from the bath, to the user 7 during bathing. It can blow air. Moreover, the noise generated from the blower unit 2 can be reduced by reducing the air volume and the wind speed.

  Further, since the outlet 2b has a slit shape extending in a direction parallel to the side wall 8 corresponding to the back surface of the user 7 during bathing, it efficiently blows the area including the shoulders and the head of the user 7 during bathing. This makes it possible to give a better feeling of exhilaration without the discomfort that the air flow hits only a part of the user 7's body.

  Further, since the outlet 2b is provided in proximity to the side wall 8, the outlet 2b is positioned almost directly above the user 7 who is taking a bath, and along the side wall 8 almost directly below the outlet 2b. By blowing out the wind, the Coanda effect can be utilized to the maximum, and the refreshing feeling by the cooling effect of the air flow can be further improved. Further, by further reducing the air volume and the wind speed by the effective Coanda effect, it is possible to reduce the noise generated from the blower unit 2.

  In addition, the suction port 2a may be configured to suck air from another place (for example, a dressing room or outside air), and the air of the other place may be blown out toward the user 7 while taking a bath in the bathtub 6. . In that case, the low-temperature low-humidity air can be applied to the user 7 in the bath 6 in the bath 6 rather than the inside of the bathroom, and the cooling effect by the air blowing becomes even greater.

  The air blowing amount of the air blowing unit 2 may be variable. A specific variable means of the air flow rate is that the motor is a DC motor and the number of rotations is changed by several notches. It is also possible to switch the number of rotations of the motor in more stages, and furthermore, instead of switching the number of rotations stepwise, it may be changed continuously.

  Moreover, as a ventilation method of the bathroom which ventilates the user in bathing, the wind ventilated from the outlet of a bathroom air blower is ventilated toward one side wall which becomes the back side of the user in bathing, It is good also as a method of blowing to a lower bathtub along with. Such a method is used as control of the blowing direction of a bathroom fan. Specifically, the above-described air blowing method can be realized by outputting a program of the air blowing method from the memory to a microcomputer or the like mounted on a circuit board that controls a bathroom fan.

  In addition, as a bathroom fan system for blowing air from the bathroom fan to the user in bathing, the wind blown from the outlet of the bathroom air blower is blown toward one side wall which is the back side of the user in bathing; It is good also as a bathroom air-blowing system which ventilates a lower bathtub along a side wall. Such a system is used as control of the blowing direction of a bathroom fan. Specifically, the above-described air blowing system can be constructed by outputting a program of the air blowing method from a memory to a microcomputer or the like mounted on a circuit board that controls a bathroom fan. As another bathroom fan system, it is also possible to use a bathroom fan system in which the communication terminal and the control unit of the bathroom fan are connected by communication and the bathroom fan operates according to an operation command from the communication terminal.

  The bathroom fan according to the present invention is an appropriate installation mode, and the user in the bath can feel the refreshing feeling by taking an air flow without feeling discomfort, and the noise is small. It is installed on the ceiling and the like, and is useful as a bathroom air blower etc. that blows air toward the user during bathing.
