An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 23 denotes a conditioned room. The harmonized room 23 is provided with a closet 24 and a top bag 25, and the top bag 25 is provided with the indoor unit 1 also serving as a futon dryer. 100 is a sliding door with a closet 24.

The indoor unit 1 is connected to an outdoor unit 2 (FIG. 2) as described later, and these constitute a refrigeration cycle. A connection duct 26 is connected to the indoor unit 1, and one end of the connection duct 26 is connected to a discharge port 27 of the indoor unit 1 and the other end is connected to an outlet 29 of the top bag 25.

The main duct 2 is provided inside the connecting duct 26.
8 is provided, and in the middle of the main air passage 28, a damper 31 is provided.
Is provided.

The damper 31 is connected to the air outlet 29 of the top bag 25,
Alternatively, an opening (hot air outlet) provided in the connection duct 26
32 is for closing one and opening the other. An elastic bellows hose 45 is connected to the opening 32 of the connection duct 26, and a cuff 72 is provided at one end of the hose 45, and the cuff 72 is attached to the partition plate 4.
6 is connected to the opening 47.

The partition plate 46 is formed by cutting out a part of a ceiling plate 48 of the closet 24 and fitted into the cutout portion. The partition plate 46 has an air communication hole 49 in addition to the opening 47. Is provided.

When the cuff 72 is connected to the opening 47, the tip of the cuff 72 protrudes into the closet 24 through the opening 47. Duct hoses (auxiliary air passages) 33 to 35 are connected to the ends, and attachments 36 to 38 are connected to the ends of the duct hoses 33 to 35. The attachments 36 to 38 ~ 41.

A flap (wind direction changing plate) 30 is provided near the outlet 29 of the connecting duct 26. 20
0 is a temperature sensor.

FIG. 2 is a circuit diagram of the refrigeration cycle.

In this figure, reference numeral 1 denotes an indoor unit, in which an indoor heat exchanger 3 is housed. The indoor side heat exchanger 3 includes a heat exchanger 3a in which a refrigerant pipe 4 through which a refrigerant (CFC) flows is incorporated;
The heat exchanger 3b is provided with a hot water pipe 5 into which hot water flows, and the heat exchanger 3a is arranged more upstream in the air path than the heat exchanger 3b.

The air passage is for guiding the air conditioned by the indoor heat exchanger 3 into the conditioned room 23, and a blower fan 99 is disposed in the air passage.

When the refrigerant is circulating in the refrigerant pipe 4,
When the pressure is reduced by the electric expansion valve 6, the refrigerant evaporates in the indoor heat exchanger 3a and cools the air (at this time, a part of the water in the air is condensed and drained). The inside is cooled. When the hot water is circulating in the hot water pipe 5, the air is heated by the indoor heat exchanger 3b, so that the inside of the conditioned room 23 is heated.

When the refrigerant and the hot water are simultaneously circulated through the indoor heat exchanger 3, the air once cooled is heated again. Therefore, by adjusting the cooling capacity and the heating capacity, the indoor heat exchange is performed. The temperature of the air after passing through the vessel 3 can be controlled. At this time, the air is dehumidified (removed of water) according to the cooling capacity during cooling.

Reference numeral 2 denotes an outdoor unit, in which a refrigerant compressor 7, an outdoor heat exchanger 8, an accumulator 9 and the like are housed.
The refrigeration cycle (refrigerant circulates in the direction of the solid arrow) is connected to the indoor heat exchanger 3, the electric expansion valve 6, and the like.

The cooling capacity of the indoor heat exchanger 3 depends on the compressor 7
Can be changed by changing the number of revolutions. When a DC motor (or DC brushless motor) is used as the drive source of the compressor 7, the number of rotations of the compressor 7 can be changed by changing the voltage of DC power supplied to the compressor. When an induction motor is used as the power source, the number of rotations can be changed by changing the frequency of AC power supplied to the compressor using an inverter device.

The electric expansion valve 6 is capable of electrically changing the throttle amount of the refrigerant by using a step motor or the like. The throttle amount controls the evaporation temperature of the refrigerant in the indoor heat exchanger 3 within a predetermined range. Adjusted to fit inside. The evaporation temperature is the temperature of the refrigerant pipe at the outlet of the indoor heat exchanger 3.

Reference numeral 10 denotes a muffler. The muffler 10 reduces the noise of the refrigerant circulating in the refrigeration cycle.

The outdoor unit 2 includes a heater 11
(For example, a burner), a heat exchanger 12, a pump 13, a pusher tank 14, and a variable flow rate valve 15 (the flow rate of hot water can be electrically changed using a step motor or the like).
And the like are further housed, and these are connected to the indoor heat exchanger 3 in an annular manner by a hot water pipe 5 to form a hot water circulation circuit.

According to this, the amount of heat radiated by the indoor heat exchanger 3 can be controlled by changing the amount of heating in the heater 11 and the amount of hot water circulation by the variable flow rate valve 15. Reference numeral 16 denotes a reserve tank, which stores excess hot water in the hot water circulation circuit, and a portion overflowing from the tank 16 is drained as drain. Reference numeral 17 denotes a pressurized water injection valve, and 18 denotes a pressurized water injection device for injecting hot water (water) into the hot water circulation circuit. Numerals 19 and 20 denote inter-unit piping for refrigerant, and 21 and 22 denote inter-unit piping for hot water, connecting the indoor unit 1 and the outdoor unit 2.

The heating amount (combustion amount) of the heater 11 is determined by the temperature of the hot water flowing through the indoor heat exchanger 3 being a predetermined value (for example, 62).
° C, 52 ° C, etc.).

In the above configuration, when the interior of the conditioned room 23 is air-conditioned by using the indoor unit 1, the damper 3 is used.
1 closes the opening 32 (FIG. 1). The damper 31 is opened and closed (or the opening is controlled) by a step motor (or a normal electric motor). When the damper 31 closes the opening 32, the conditioned air flows into the conditioned room 23 through the outlet 29 of the top bag 25. It is blown out and air-conditions it.

At this time, the direction of the air blown into the conditioned chamber 23 is adjusted by the flap 30 described above. That is, the above-described flap 30 is driven by a step motor, and when the step motor is rotated by an arbitrary number of revolutions, the wind direction of the air-conditioned air is changed to an arbitrary direction, and the step motor is rotated by an arbitrary number of revolutions. When rotated alternately, the blowing direction of the conditioned air swings up and down.

On the other hand, when the damper 31 closes the outlet 29 of the top bag 25, the conditioned air is guided to the duct hoses (sub-airways) 33 to 35 through the openings 32.
Through the attachments 36 to 38 at the tip, the futon 3
It blows out between 9-41 and dries the futons 39-41.

When the opening degree of the damper 31 is controlled to the intermediate position, the conditioned air is guided to both the conditioned room 23 and the duct hoses 33 to 35, and air-conditions the conditioned room 23. Then, the futons 39 to 41 are dried.

According to this embodiment, the connection structure between the duct hoses 33 to 35 and the attachments 36 to 38 is characterized.

Referring to FIG. 3, duct hoses 33 (to 3)
At the end of 5), a cuff 101 is provided.
01 is connected to an attachment 36 (-38).
The cuff 101 is, as shown in FIG.
3 and an outer sleeve 83 connected to the attachment 36, and these 81 and 83 can be rotated mutually.

As shown in FIG. 3, the inner and outer sleeves 81 and 83 are connected by a lock member 85 fitted into a notch 83a of the outer sleeve 83. More specifically, as is apparent from FIGS.
It is engaged with the step portion 81a of the inner sleeve 81 to prevent it from coming off in the axial direction.

According to this, when the duct hose 33 is extended, the spiral winding 33 wound around it is extended.
a (FIG. 4a), even if the duct hose 33 is twisted in the circumferential direction due to the twisting action of the attachment 36a.
Are not integrally rotated in the circumferential direction.

That is, even if the duct hose 33 rotates in the circumferential direction, the twist is transmitted to the inner sleeve 81 but not to the outer sleeve 83. Therefore, the rotation of the duct hose 33 is not transmitted to the attachment 36 connected to the outer sleeve 83, and the duct hose 33
No twisting occurs at the connection portion (the portion of the cuff 101) between the cable and the attachment 36.

The outer sleeve 83 and the attachment 36
Any connection may be used, for example, a concave portion is provided on the inner periphery of the outer sleeve 83,
It is preferable that the connection is made by fitting the convex portion on the outer periphery of the attachment 36 into the concave portion.

[0040]

As is apparent from the above description, according to the present invention, the cuff is constituted by the inner and outer sleeves and the connecting member for connecting the inner and outer sleeves to each other so that they can rotate.
Even if the duct hose connected to the inner sleeve is twisted, the twist is not transmitted to the attachment connected to the outer sleeve, and the connection between the duct hose and the attachment becomes extremely simple.
