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 outlet 29 of the top bag 25,
Alternatively, one of the openings 32 provided in the connection duct 26 is closed and the other is opened. An elastic bellows hose 45 is connected to the opening 32 of the connection duct 26, and a cuff 72 is connected to one end of the hose 45, and the cuff 72 is connected to the opening 47 of the partition plate 46. 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.

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

In FIG. 1, 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 on the windward side of 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 at a predetermined value (for example, 62).
° C, 52 ° C, etc.).

In the above structure, 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 of the damper 31 is controlled to the intermediate position, the air-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.

FIGS. 3 and 4 are views for explaining the attachments 36 (-38) constituting the main part of the present embodiment.

The attachment 36 (.about.38) is made of resin and has a flat insertion portion inserted between the cylindrical connection port 36a connected to the duct hose 33 (.about.35) and the futon 39 (.about.41). 36b.

As is clear from FIG. 3, the attachment 36 is formed by connecting a pair of front and back elements 51a and 51b with a plurality of screws 53, and the head of the screw 53 extends from the surface of the attachment 36. The screw hole of the attachment 36 is counterbored so as not to protrude.

The pair of elements 51a and 51b have the same shape, and when an element of the same shape is superimposed on the front element 51a, the element constitutes the back element 51b.

For example, the screw hole 5 is inserted in the element 51a of the table.
3a, a boss 54 is provided at that position of the back element 51b coupled thereto, and the boss 5
4 is formed with an internal thread, and by screwing a screw 53 into the internal thread, the two are connected.

Accordingly, when considering the manufacturing stage of the attachment 36, only one die is required for manufacturing the elements 51a and 51b, so that the manufacturing cost required for the die can be reduced.

When the respective elements 51a and 51b are overlapped, a bag-like space for guiding warm air is formed therein. Hot air is introduced from the connection port 36a of the attachment 36, passes through the space, and passes through the insertion portion 3a.
6b is blown out from the plurality of hot air outlets 55 between the futons 39 to 41.

As shown in FIGS. 4A to 4C, the hot air outlet 55 is provided in the concave groove 61 on the surface of the insertion portion 36b, and is also provided on the peripheral edge 63 of the insertion portion 36b. To 41, the hot air outlet 55 does not come into close contact with the futons 39 to 41.

In the internal space near the connection port 36a, projections 65a and 65b for distributing warm air introduced from the connection port 36a to the left and right are provided.
5 is integrally formed inside the elements 51a and 51b.

According to this, not only the introduced warm air is efficiently distributed to the left and right, but also the protrusions 65a, 65b
Contact, the strength of the attachment 36 can be improved. Further, the thickness t of the attachment 36
As shown in FIG. 4c, the attachment 36 is thinned toward the tip so that the attachment 36
Can be easily inserted. Since the head of the screw 53 does not protrude from the surface of the attachment 36, there is no fear of damaging the fabric of the futons 39 to 41.

According to this embodiment, since the attachment 36 diffuses and supplies air widely and uniformly between the futons 39 to 41, the futons 39 to 41 can be dried efficiently. To play.

FIG. 5 shows an operation section of the futon dryer. The operation unit 81 includes a rotary timer 82, a lamp 83 that is turned on when the timer 82 is used, a lamp 84 that is turned on when the air conditioner is on, and whether the air conditioner is used as an air conditioner or a futon dryer. The switch 85 includes a switch 85 for switching whether to use the futon and a switch 86 for switching depending on the type of futon.

The changeover switch 86 is switched as follows. That is, when the detection value of the temperature sensor 200 (FIG. 1) in the connection duct 28 is, for example, 50 ° C., it is switched to the “cotton” side, and when it is 45 ° C., “wool”
Is switched to the side.

In the futon dryer described above, it is necessary to cool the futon which has been heated by drying. In this embodiment, after the set time of the timer 82 (FIG. 5) has expired, by operating both heat exchangers 3a and 3b with reference to FIG.
Can be cooled.

According to this, as compared with the case where only air is blown for cooling the futon, as shown in FIG. 6, the cooling can be performed while keeping the humidity low.

When the final operation mode of the indoor unit 1 is cooling (summer), the operation time for futon cooling is as follows:
The timer set by the user is set to about 1/4 of 82 hours, and when the final operation mode of the indoor unit 1 is heating (in winter), the operation time for futon cooling is set by the user. It is set to about 1/8 of the time of the timer 82. This is to ensure that the futon is sufficiently cooled in summer and not so much in winter.

[0046]

As is apparent from the above description, according to the present invention, even when the futon is folded, the attachment can be easily inserted between the futons, and the futon can be efficiently placed. Can be dried.
