Also provided is a nozzle 5 which is normally stored in a storage recess 6 and pulled out when in use.

Inside the main body 1 of the air conditioner with air shower, a partition wall 14 having spot vents 15 allows an air conditioner A having an air intake port 2 and an air conditioning outlet 3 on the bottom surface, and an air shower having a nozzle 5 on the bottom surface to be connected to each other. It is divided into D and
The air conditioner A is provided with a filter 21 and a room temperature thermistor 22 inside the intake port 2, and a refrigerant reciprocating pipe 71 is connected to the outdoor unit (not shown) in the flow path from the intake port 2 to the air conditioning outlet 3. An indoor heat exchanger 7 for air conditioning is connected to the indoor heat exchanger 7 for air conditioning, and an indoor heat exchanger 8 for heating is connected to a hot water heat source device (not shown) by a hot water reciprocating pipe line 81 having a hot water regulating valve 80 in the hot water supply pipe. An indoor fan 13 is arranged in order, and an indoor heat exchanger 7 for cooling
A heat exchanger temperature detection thermistor 9 is provided in contact with the heating indoor heat exchanger 8, and the louver 4 disposed at the air conditioning outlet 3 is connected to the arm 4 of the auto louver motor 41.
They are connected via 2.

A drain pan 10 is disposed below the indoor heat exchanger 7 for cooling and the indoor heat exchanger 8 for heating, and a drain reservoir 101 is continuously provided on the side of the drain pan 10. is provided with a detection electrode 11 and a drain pump 12 for detecting the liquid level of the stored drain;

During air conditioning operation, indoor air is sucked in from the intake port 2 (arrow F1), and cold air cooled by the cooling indoor heat exchanger 7 (during cooling) or heated indoor heat exchanger 8 is used.
The indoor fan 13 blows warm air (during heating) heated by the
2) It is something.

The air shower D is equipped with an air shower spot fan 17 equipped with a filter 18 at the intake port at one end, and is equipped with a hot air ceramic heater 19, a thermal fuse 190, and a heating prevention switch 191 inside. A shower case 16 is installed, and a nozzle 5 is rotatably connected to the other end of the air shower case 16 so that its angle with respect to the air shower case 16 can be adjusted. 7 and the air on the downstream side of the heating indoor heat exchanger 8 and blows it from the nozzle 5. When the air shower D is in operation, there is a risk that indoor air will be sucked from the air conditioning outlet 3.
At this time, by setting the indoor fan 13 to a gentle breeze operation, suction of indoor air can be suppressed.

The connecting end of the nozzle 5 to the air shower case 16 is supported by a rotating shaft 50 and rotated by a motor 51 to adjust the angle of the nozzle 5 with respect to the air shower case 16. A nozzle position detection device 52 for detecting an angle with respect to 16 is disposed.

The air shower D is capable of blowing out hot air or cold air as needed, and when operating to blow out hot air, the angle of the nozzle 5 with respect to the air shower case 16 is adjusted to move the nozzle 5 into the sanitary space. When hot air is required, the ceramic heater 19 is energized to heat the air from the spot fan 17 and blow hot air. However, depending on the strength of the operation mode and the intake air temperature, the hot water adjustment valve 80 is turned on when necessary to operate the heating indoor heat exchanger 8 of the air conditioner A, and the intake air temperature of the spot fan 17 is adjusted. is increased to make the temperature of the hot air blown out from the nozzle 5 sufficiently high (backup operation).

On the other hand, when cold air is required, the cold air obtained by operating the cooling indoor heat exchanger 7 of the air conditioner A is sucked into the air shower D through the spot vent 15, and is then sucked into the air shower D from the nozzle 5 by the spot fan 17. It blows air.

Next, the movement of the nozzle 5 of the air shower D will be explained in detail with reference to FIGS. 3 and 4. In the retracted state of the nozzle 5 shown in FIG. The angle θ0 formed by the center line l of the nozzle 5 when stored is a large value (for example, 90 degrees),
When drawing out the nozzle 5 shown in FIG. 4, that is, air shower D
When in use, the angle formed by the center line L of the air shower case 16 and the center line L of the nozzle 5 when stored is set to a predetermined angle θ1 (for example, 30 degrees) or less to reduce the flow path resistance of the air blow path. Then, the spot fan 17 and the ceramic heater 19 are energized and operated.

In FIGS. 5 and 6, a nozzle position detection device 52 that detects the angle θ of the nozzle 5 with respect to the air shower case 16 is connected to a disk 520 fixed to a drive shaft 510 of a motor 51, and a light emitting section and a light receiving section. It consists of a photointerrupter 522, with a notch 521 in a disk 520.
A photo interrupter 52 is provided with a disk 520 in between.
2, the light emitting part and the light receiving part are located, and the above notch 5
21 is formed so that one end of the notch 521 on the side far from the photointerrupter 522 coincides with the center line l of the nozzle 5, and is formed with a predetermined center angle θ1 (30 degrees).

In the stored state shown in FIG. 6, the light emitting part and the light receiving part of the photo interrupter 522 placed on the center line L of the air shower case 16 are blocked by the disk 520, and the angle θ0 from the photo interrupter 522 is
One end of the notch 521 on the far side from the photointerrupter 522 (coinciding with the center line l of the nozzle 5) is located at a position shifted by (90 degrees), and from there, the photointerrupter 5
A notch 521 is located on the 22 side.

Now, when the air shower D is in use (
(see FIG. 4), when the nozzle 5 is rotated to protrude and the angle formed by the center line L of the air shower case 16 and the center line L of the nozzle 5 becomes less than a predetermined angle θ1 (30 degrees),
The notch 521 coincides with the photointerrupter 522, and the photointerrupter 522 outputs a detection signal to enable the ceramic heater 19 to be energized.

Note that the center line L of the air shower case 16 and the nozzle 5 that enable electricity to be supplied to the ceramic heater 19
The predetermined angle θ1 formed by the center line 1 during storage is set to a value that does not reduce the amount of air blown, taking into consideration the overall structure of the air shower D (in this embodiment, θ1 = 30 degrees).

As mentioned above, it is ensured that the angle formed by the center line L of the air shower case 16 and the center line L of the nozzle 5 is below a predetermined angle θ1 (30 degrees) that does not reduce the air flow rate. There is no fear that the ceramic heater 19 will overheat by enabling the ceramic heater 19 to be energized after detecting that the amount of air is sufficient.

[0022] Here, in the above embodiment, the nozzle position detecting device uses a disk fixed to the drive shaft of the motor and a photointerrupter consisting of a light emitting part and a light receiving part. The configuration of the position detection device is not limited to this, and for example, a limit switch or the like may be used.
