[0028]
The electrical box 52 is provided with a control device (not shown) for controlling the bathroom heating device 1 by controlling electric components such as the heat source device 3 and the bathroom heater 2, and this control device is connected to the signal line 8. And connected to the heat source unit 3 and the remote controller 7.
[0029]
FIG. 8 is a front view of the remote controller. In FIG. 8, the remote controller 7 is provided with a display unit 61 for displaying on / off of driving, heating temperature, timer time, and angle of the louver 17 and an operation unit 62 with operation switches. The unit 62 includes operation switches 63 to 66 for turning on / off the operation of the bathroom heater 2 in each operation mode of heating, drying, ventilation, and cool air, a temperature switch 67 for setting a set temperature, and a timer switch for setting a timer time. 68 and a wind direction switch 69 for changing the angle of the louver 17 to set the blowing direction to an appropriate direction or to swing the louver 17.
[0030]
Next, the operation of the bathroom heater in each operation mode will be described.
[0031]
When the heating switch 63 is turned on and the heating operation mode is commanded, the control device executes the heating operation in which the circulation fan 43 is operated with the ventilation fan 54 stopped. In this heating operation mode, hot water is circulated and supplied to the heat exchanger 38 by controlling the opening and closing of the thermal valve 42 so that the temperature in the bathroom A is maintained within a preset temperature range. Then, as shown by a solid line arrow in FIG. 5, the air in the bathroom A is sucked through the suction port 14, and the air heated by the heat exchanger 38 is blown out from the blowout port 15 to the bathroom A to perform the heating operation.
[0032]
When the ventilation switch 65 is turned on and the ventilation operation mode is commanded, the control device stops the circulation fan 43, closes the thermal valve 42, and executes the ventilation operation for operating the ventilation fan 54. In this ventilation operation mode, air drawn from the dressing room C through the bathroom A and the intake duct 5 is exhausted to the outside through the exhaust duct 6 as indicated by broken line arrows in FIG. At this time, since the operation of the circulation fan 43 is stopped, the direction of the louver 17 is closed. When the set time elapses after the ventilation operation is commanded or the ventilation switch 65 is operated again, the ventilation operation is terminated.
[0033]
When the cool breeze operation switch is turned on and the cool breeze operation mode is commanded, the control device closes the thermal valve 42 and executes the cool breeze operation that operates the circulation fan 43 and the ventilation fan 54. In this cool breeze operation mode, as shown by the solid line arrow in FIG. 5, the air sucked from the bathroom A is returned to the bathroom A through the ventilation path 37 without being heated, and as shown by the broken line arrow in FIG. A part of the air sucked from the air and the air sucked from the dressing room C through the intake duct 5 are discharged to the outside through the exhaust duct 6. The direction of the louver 17 is set to be the same as that in the heating operation, for example. When the set time elapses after the cool wind operation is commanded or when the cool wind switch 66 is operated again, the cool wind operation is terminated.
[0034]
When the drying switch 64 is turned ON and the drying operation mode is commanded, the control device executes a drying operation for operating the circulation fan 43 and the ventilation fan 54. In this drying operation mode, the opening and closing of the thermal valve 42 is controlled so that the temperature in the bathroom A is maintained within a preset temperature range for drying, and the heat exchanger 38 is used as a heat medium. Circulate hot water. And as shown to the solid line arrow of FIG. 5, while sucking the air of the bathroom A through the suction inlet 14, the air heated by the heat exchanger 38 is blown out to the bathroom A from the blower outlet 15, and it shows to the broken line arrow of FIG. As described above, a part of the air sucked from the bathroom A and the air sucked from the dressing room C through the intake duct 5 are discharged to the outside through the exhaust duct 6. In this drying operation mode, for example, when clothes and the like are suspended in the bathroom A and dried, the air blowing direction into the bathroom A is directed to an object to be dried such as clothes by a louver motor (not shown). Adjust the direction of the louver 17. Moist air that evaporates from the object to be dried and contains moisture is sucked from the suction port 14, heated by the heat exchanger 38, and blown out again into the bathroom A. Discharged to the outdoors. When the set time elapses after the drying operation is commanded or when the drying switch 64 is operated again, the drying operation is terminated.
[0035]
As described above, the bathroom heater 2 of the present embodiment is provided with two openings on the main body side plate 18, and these openings can be connected to either the intake duct 5 or the exhaust duct 6, and Since the outlet of the ventilation fan case 56 can be selected and directed, the duct piping work can be facilitated by properly using the opening for intake and exhaust according to the arrangement of the duct piping.
[0036]
Furthermore, since the connection adapter 28 can be connected to the duct connection parts 24 and 25 by being inverted 180 degrees, as shown in FIGS. 9 to 11, the connection adapter 28 can be attached to the main body in three ways. is there. By selecting and installing the extending directions of the intake duct 5 and the exhaust duct 6, it is possible to simplify the arrangement of the duct piping and facilitate the piping work.
[0037]
As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this.
[0038]
In the present embodiment, the curved pipe-shaped connection adapter 28 bent at 90 degrees is used, but a straight pipe-shaped connection adapter or a curved pipe-shaped connection adapter having an angle of 90 degrees or more may be used.
[0039]
In this embodiment, the bathroom A and the dressing room C are ventilated. However, as shown in FIG. 12, only the bathroom A can be ventilated without ventilating the dressing room C. In that case, it is necessary to close the opening of the duct connecting portion 24 (or 25) for the intake duct, and after the intake mounting frame 26 is attached to the duct connecting portion 24 (or 25), a closing plate (not shown) is attached. Install and close.
[0040]
【The invention's effect】
As described above, in the bathroom heater of the present invention, a ventilation chamber containing a ventilation fan and a ventilation fan having a ventilation fan case is formed inside a box-shaped main body case installed behind the ceiling of the bathroom. In addition, a heat exchanger chamber in which a heat exchanger and a circulation fan are accommodated is formed, and in the bathroom heater that performs heating and ventilation of the bathroom, the ventilation fan is arranged at a corner portion in the main body case, The ventilating fan case outlet is arranged to be selectable in any one of two orthogonal directions, and a plurality of side plates orthogonal to the main body case correspond to the venting fan case outlet. Each of the openings for connecting ducts is provided, and a connection adapter is provided in one of the openings of the main body case facing the discharge port of the ventilation fan case. And an exhaust duct connected to, and, the other opening of the body case, connect the intake duct through a connection adapter, or from the configured for closing at the closing plate, the arrangement of the exhaust duct and the intake duct It can be changed, and duct piping work can be facilitated and work efficiency can be improved.
[0041]
[0042]
In addition, since the duct piping work of the intake duct and the exhaust duct is facilitated, the efficiency of the installation work of the bathroom heater can be improved.
