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

In the figure, reference numeral 1 denotes an indoor unit, and the indoor unit 1 accommodates an indoor heat exchanger 3. The indoor 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 through which hot water flows, and the heat exchanger 3a is arranged on the windward side of the heat exchanger 3b.

This air passage is for guiding the air conditioned by the indoor heat exchanger 3 into the conditioned chamber 23, and a blower fan 99 is arranged in the air passage.

When the refrigerant is circulating in the refrigerant pipe 4,
By reducing the pressure 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. Further, when the warm water is circulating in the warm water pipe 5, the indoor heat exchanger 3b heats the air, so that the inside of the conditioned chamber 23 is heated.

When the refrigerant and hot water are circulated in the indoor heat exchanger 3 at the same time, the air that has been 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. The air at this time is dehumidified (water content is removed) according to the cooling capacity during cooling.

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

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

The electric expansion valve 6 can electrically change the throttle amount of the refrigerant using a step motor or the like, and the throttle amount is such that the evaporation temperature of the refrigerant in the indoor heat exchanger 3 falls 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.

A muffler 10 is provided to reduce the noise of the refrigerant circulating in the refrigeration cycle.

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

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

The heating amount (combustion amount) of the heater 11 is a predetermined value (for example, 62) of the temperature of the hot water flowing through the indoor heat exchanger 3.
It is automatically controlled so that the temperature becomes ℃, 52 ℃, etc.).

In the above structure, when the interior unit 1 is used to air-condition the inside of the controlled room 23, the damper 3
1 closes the opening 32 (FIG. 1). The damper 31 is opened / closed (or its opening is controlled) by a step motor (or an ordinary electric motor), and when the damper 31 closes the opening 32, the conditioned air is blown into the conditioned chamber 23 through the air outlet 29 of the bag 25. It is blown out and air-conditioned there.

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

On the other hand, when the damper 31 closes the air outlet 29 of the top bag 25, the conditioned air is guided to the duct hoses (auxiliary air passages) 33 to 35 through the opening 32.
Futon 3 through the attachments 36-38 at its tip.
Blown between 9 and 41 to dry the futons 39 to 41.

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

However, this embodiment is characterized by the connection structure between the duct hoses 33 to 35 and the opening 47 of the partition plate 46.

As described above with reference to FIGS. 3 and 4, the cuff 72 of the bellows hose 45 is connected to the opening 47 of the partition plate 46, and the tip portion 72a of the cuff 72 is connected.
Faces into the closet 24.

As shown in FIG. 5, the front end portion 72a facing the inside of the push-in 24 is provided with two opening portions 112 and 113 with a thin partition wall portion 111 interposed therebetween. The opening 112 from the tip has an opening 112a on the tip surface side of the cuff 72,
A catch groove 112b is provided in the inner portion on the partition side.

In the catch groove 112b, a connecting member 115 provided on the inner circumference of the cuff 114 of the duct hose 33 is provided.
Is received, and the cuff 114 and the tip portion 72a are connected by this. That is, the thickness t of the connector 115
Is formed to be slightly thinner than the groove width w of the catch groove 112b so that it fits snugly in the catch groove 112b.

The thin partition wall portion 111 has an opening 11
A concave portion 111a that bulges on the 3 side is provided, and the connecting body 1
A protrusion 115a that engages with the recess 111a is provided on the portion 15.

When the connecting body 115 of the cuff 114 is fitted into the catch groove 112b, first, as shown by the arrow in FIG. 5, the connecting body 115 is opened through the opening 112a.
Push in 2.

At this time, the projection 115a provided on the connecting member 115 presses the thin partition wall portion 111 toward the opening portion 113 side and bends it toward the opening portion 113 side. In this state, when the cuff 114 is rotated counterclockwise in the figure, the protrusion 115a of the connecting body 115 causes the thin partition wall portion 111 to move.
While being bent, fit into the catch groove 112b. That is, at the stage of fitting the connecting body 115 into the catch groove 112b, the thin partition wall portion 111 remains curved.

When the connecting body 115 is completely fitted in the catch groove 112b, the projection 115a of the connecting body 115 is fitted in the recess 111a of the thin partition wall portion 111, and the thin partition wall portion 11 is formed.
1 restores the original state from the curved state.

As a result, as shown in FIGS. 6a and 6b, the cuff 114 and the tip portion 72a are connected. According to this, since the cuff 114 and the tip portion 72a are in a locked state, these structures constitute so-called locking means.

The state of connection between the cuff 114 and the duct hose 33 will be described with reference to FIG. 6a.
14 is an inner sleeve 121 connected to the duct hose 33.
And the outer sleeve 1 connected to the tip portion 72a of the cuff 72
23, and these 121 and 123 can rotate relative to each other.

As shown in FIG. 5, the inner and outer sleeves 121 and 123 are connected by a connecting member 125 fitted in a notch 123a of the outer sleeve 123. Specifically, the connecting member 125 is As is clear from 6a, it engages with the stepped portion 121a of the inner sleeve 121 to prevent it from coming off in the axial direction.

According to this, when extending the duct hose 33, the spiral winding 33 wound around the duct hose 33.
Even if the duct hose 33 is twisted in the circumferential direction due to the twisting action of a (FIG. 6A), the twist is transmitted only to the inner sleeve 121 and not to the outer sleeve 123.

Therefore, even if the duct hose 33 is twisted, an unreasonable force does not act on the connecting portion between the duct hose 33 and the tip portion 72a.

Although the present invention has been described based on the embodiment, the present invention is not limited to the connection between the tip portion 72a of the cuff 72 and the cuff 114 of the duct hose 33, but the duct hose 33. It goes without saying that this can be applied between the attachment and the attachment 36.
