Next, the working principle will be described with reference to FIG. 5 and FIG. 6 . During cold air operation, the heat exchange medium compressed by the compressor and turned into a high temperature state is sent to the outdoor heat exchanger of the outdoor unit. At the outdoor heat exchanger, outside air flows through the outdoor heat exchanger under the action of the outdoor fan, and the heat exchange medium is cooled while it absorbs heat from the heat exchange medium. The heat exchange medium evaporates and gasifies in the indoor heat exchanger 25 of the indoor unit 1 through the expansion valve, and the indoor air flows through the indoor heat exchanger 25 under the action of the indoor fan 26 to absorb the heat of the indoor air. As a result, the indoor air becomes colder, realizing cooling of the room. When heating the room, contrary to the cold wind operation, it is realized by the reverse circulation of the heat exchange medium. The compressed heat exchange medium is sent to the indoor heat exchanger 25 of the indoor unit 1, and the indoor air flowing through the indoor heat exchanger 25 is warmed to heat the room. The heat exchange medium then evaporates in the outdoor heat exchanger of the outdoor unit through the expansion valve, and the outdoor air flows through the outdoor heat exchanger under the action of the outdoor fan for heat exchange, thereby absorbing heat from the outdoor air and returning to the compressor. Under the action of the indoor fan 26, the indoor air flows through the indoor heat exchanger 25, thereby realizing the absorption of the heat of the indoor air.

The entire surface of the heat exchanger 25 sucks the indoor air, and therefore, the heat exchange efficiency of the indoor heat exchanger 25 is high and the coefficient of performance is also improved.

The dehumidification device (not shown) installed on the right side of the main body 2 of the indoor unit 1 sucks the air to be dehumidified from the suction port 13 of the main body 2 through the filter 13 . In a dehumidifier, for example, during humidification operation, moisture in indoor air is absorbed, dry air is discharged outdoors, and humid air is discharged indoors. Conversely, it is also possible to perform a dehumidification operation in which humid air is discharged outside and dry air is discharged indoors. The blower port 4 of the cold and warm air generated by the operation of the compressor and the blower port 7 of the dehumidification device are separately installed on the left and right, so the installation positions of the suction port and the blower port of the indoor air are not mixed, so even if they are operated at the same time, there is no problem. A short circuit occurs due to the flow of wind.

As can be seen from the above description, the present invention is such an air conditioner, that is, a main body is provided with a suction port on the front and top of the casing, a grille opening formed on the upper part of the front, and an air outlet formed on the lower part of the front. The main body is formed by installing a front panel formed with a suction port. A heat exchanger and a fan for driving air blowing are installed in the above-mentioned body, and there is a filter from the front of the above-mentioned opening to the back of the upper suction port of the above-mentioned body shell. The air conditioner is equipped with a dehumidification device for dehumidification and humidification of indoor air. A large liquid crystal display device facing downwards and showing the operating status is installed in the approximate center of the body. Because the liquid crystal display The device faces downward at the central position, so the display content of the liquid crystal display device is very easy to observe.

In addition, a space is provided between the above-mentioned large liquid crystal display device and the heat exchanger, and a suction port is provided slightly above the liquid crystal display device, and the airflow sucked from the suction port flows through the periphery of the liquid crystal display device and flows toward the heat exchanger. , and thus, the efficiency of heat exchange with room air at the heat exchanger is improved.

In addition, the air outlet of the above-mentioned dehumidification device blowing into the room is arranged laterally with the air outlet of the above-mentioned body shell, so the blowing of cold and warm air into the room and the air blowing of the dehumidification device into the room are carried out on the same surface, so it can prevent short circuits.

In order to allow regeneration air to pass through, A hole that accounts for about half (about 180 degrees) of the area is opened on the bottom surface. On the side opposite to this hole, a hole 57c of about 60 mm through which the air flowing through the moisture absorbing impeller 39 passes is provided. In addition, on the surface opposite to the mounting surface of the moisture absorption impeller 39, there is a standing wall 57b of a housing for the moisture absorption fan 51 that sucks in room air through the moisture absorption impeller 39. As shown in FIG. On the downstream side of the passage, there is a passage leading to the damper device 58 for passage switching, and holes are provided at many places for installing a metal housing 60 in which a regeneration heater 42 for heating the air for regeneration is installed. .

On the left side of the casing L57, there is a damper device 58 composed of two transparent resin casings in which the damper 60 is incorporated. On the housing L59 of the damper device 58 on the housing L57 side, an inlet 59a for entering the dry air from the moisture absorbing fan 51 is provided for entering the inlet 59b for the air that is separated from moisture by the moisture absorbing impeller 39 and becomes humid. The pipe connection port 59c provided at the outlet of the outdoor exhaust. In addition, a hub for the damper 60 bearing is provided at the center, and a support portion for the reduction gear 63 of the damper driving motor 62 is provided nearby. The other casing R61 of the damper unit 58 is provided with a room exhaust port 61a for returning air to the room, and a hole for installing a motor for driving the damper 60 is provided in the vicinity thereof. The damper 60 has a hub having a bearing in the center, gears are arranged on about 1/4 of the outer periphery, and a wall for switching the passage of air is provided.

The assembly step of the dehumidification device 24 is to install the motor mounting plate on which the regenerative fan 41 and the motor are fixed on the predetermined position of the housing L56 through screws, make the side of the gear on the outer periphery of the moisture absorption impeller 39 face the side of the housing L56, and insert Attach to the shaft of the housing L56. Furthermore, the reduction gear 50 is also installed at a predetermined position. The metal housing 60 incorporating the regenerative heater 42 is assembled at a predetermined position of the housing R57, and the housing R57 is combined with the housing L56 and fixed with screws. At this time, through the notch 56b of the housing L56, the moisture-absorbing impeller 39 can be rotated by hand, and it can be checked by hand whether there is deviation, bumping, etc. during the rotation. Furthermore, a metal mounting plate on which the motor of the moisture absorption fan 51 is mounted is fixed to a predetermined position on the side of the metal cover 60 of the housing R57 with screws. Finally, the damper device 58 equipped with the damper 60, the damper motor 62, etc. is installed on the housing L56, and the assembly of the dehumidifier 24 is completed.

Next, the function and structure of the dehumidifier and the air flow and humidification operation will be described. The air sucked from the room is sucked from the suction port 5 on the front of the front panel 3 and the suction port on the body shell 2 top, and is drawn to the left side of the moisture absorption impeller 39 through the filter 13 . The two faces of moisture-absorbing impeller 39 are formed with each ventilation path formed with the angle shown in Fig. 16, in order to prevent air from leaking at the position contacting with the turntable, seal with the rubber seal that fits the turntable surface with its shape. When the air inhaled by the hygroscopic fan 51 flows through the area A of 1/2 (180 degrees) of the side of the turntable as shown in FIG. Then it becomes dry air. The dry air flows through the exhaust pipe 52 and is discharged outdoors under the action of the multi-blade fan driven by the motor of the moisture absorption fan 51 . Under the action of the motor of the regenerative fan 41, the sucked air flows through the area of 1/8 (45 degrees) of the side of the moisture absorption impeller 8 shown in the area B and area D of Fig. 16, and leaves the moisture absorption impeller 39 on the right. The side surface returns in a U shape and is led to the regenerative heater 42; when passing through area B, the same as above, the moisture in the air will be adsorbed on the hygroscopic material of the turntable. But, because the hygroscopic impeller 39 rotates at a slow speed, this area B arrives after the air passes through the area A. Therefore, the moisture absorption efficiency of the area B to moisture is not higher than that of the area A. And when flowing through the area D, since the area D comes after the area C of the moisture absorbing impeller 39, the temperature of the ceramic parts constituting the moisture absorbing impeller 39 has not been sufficiently reduced, so the adsorption of moisture in the area D is also small. The air flowing through areas B and D is heated to a high temperature when passing through the regenerative heater 42, and then flows from the right side of the moisture absorption impeller 39 through the area C shown in FIG. (90 degrees) area of the area flows to the left. At this time, the moisture adsorbed on the hygroscopic material of the moisture absorbing impeller 39 is separated from the hygroscopic material by heating. As a result, air containing a large amount of moisture enters the regeneration fan 42 from the right side of the moisture absorbing impeller 39 and is blown out from the air outlet 7 into the room.

With the above-described functions and structures, dry air is discharged outside, and moisture is stored indoors to perform humidification.

During the assembly process of the dehumidifying device 24 assembled as above, the hygroscopic impeller 39 can be checked and confirmed by hand through the gap 56b of the housing R56, so that the inspection can be carried out as early as possible, and the time can be greatly shortened in case of any failure. The time required to perform the decomposition.

In addition, the driving motor 49 of the moisture-absorbing impeller 39 is installed outside the casing, so maintenance can be performed without disassembly, avoiding waste of time.

As can be seen from the above description, the present invention belongs to a rotating body coated with a hygroscopic material that can absorb and separate moisture in the air, a hygroscopic fan that sucks in indoor air, and a heating system that heats the air that separates moisture from the hygroscopic material. body, and a regenerative fan that sends heated air into the dehumidification device, the indoor unit of the air conditioner, wherein the drive motor that drives the above-mentioned rotating body coated with hygroscopic material is arranged outside the casing, and a gap is provided, Therefore, it is possible to check by hand through the gap to detect problems as early as possible. In the event of a bad situation, the time required for disassembly can be greatly shortened. By installing the drive motor of the moisture-absorbing impeller outside the housing, maintenance can be performed without disassembly , to avoid wasting time.

In addition, the supporting part of the driving gear that transmits the rotational driving force of the above-mentioned motor to the above-mentioned rotating body coated with hygroscopic material is provided on the side of the housing on the same surface as the rotating body, so that the cooperation between the rotating body and the driving gear Status is easy to grasp.

Implementation form 3

Next, Embodiment 3 of the present invention will be described with reference to FIGS. 17 to 21. FIG.

As shown in Figure 17 and Figure 18, the refrigerant pipes 71, 72, drain hose 73, power cord 74 and ventilation pipe 75 are drawn from the indoor unit A (refer to Figure 25), and pass through the pipes opened on the wall 76 at the back of the indoor unit. The hole 77 leads to the outside. In the present invention, in particular, an auxiliary duct 78 shown in FIGS. 17 and 18 is connected to the outdoor side end of the ventilation duct 75 .

The auxiliary duct 78 is molded, for example, from hard resin, and has a connection portion 79 connected to the ventilation duct 75 and a substantially semicircular outlet-side end portion 80 . As can be seen from FIG. 20 , the outlet-side end portion 80 is twisted about 90 degrees with respect to the connecting portion 79 and formed.

In this example, since the cross-sectional shape of the ventilation duct 75 is roughly a semicircle, the connecting portion 79 is also made into a roughly semicircle correspondingly, but it is not limited to a roughly semicircle, as long as it is in line with The cross-sectional shape of the ventilation duct 79 may have a corresponding shape.

A rainproof rain cover 81 is installed on the outdoor surface of the wall 76, and various piping and ventilation ducts 75 and auxiliary pipelines 78 are led in the rain cover 81. The air discharged from the ventilation duct 75 and the auxiliary duct 78 by the indoor unit A is discharged to the outside through the vent 82 provided on the rainproof cover 81 .

When piping such as refrigerant pipes 71, 72, drain hose 73, and power cord 74 needs to be bent so as to intersect with the axis of the ventilation pipe 75 in the longitudinal direction, it is only necessary to twist the auxiliary pipe 78 approximately 90 degrees. The bottom of the semicircular outlet side end 80 can be bent along its torsion part, and various pipes can be bent to be compatible with the rain cover 81 without passing between the outlet side end opening 83 of the auxiliary pipe 78 and the rainproof cover 81. The air ducts 75 intersect and lead out, so the reduction of the circulation efficiency of air circulating in the ventilation ducts can be avoided.

In addition, in this embodiment, in order to adapt to the situation where the piping hole 77 is small and the ventilation duct 5 with a small diameter has to be used, the connecting portion 79 of the auxiliary duct 78 is provided with a large diameter portion 79a and a small diameter portion in a stepped shape. The connecting portion 79 of the portion 79b has cross-sections with different diameters. Therefore, when the diameter of the ventilating duct 75 to be connected is small, it can be directly connected to the ventilating duct 75 by simply cutting off the large-diameter portion 79 a.

In addition, in this embodiment, the outlet side end opening 83 of the auxiliary pipe 78 is cut obliquely, so when it is drawn out to the rainproof cover 81, even if it contacts the wall surface of the rainproof cover 81, it will not hinder Air circulation ensures good ventilation. In the illustrated example, the outlet-side end opening 83 is cut obliquely upward, but the direction is not limited as long as it is cut obliquely.

As described in detail above, in the air conditioner based on the present invention, such an auxiliary duct is connected to the outdoor side end of the ventilation duct, that is, the connecting portion connected to the ventilation duct has a twisted angle of about 90 degrees. The outlet side end is approximately semicircular, so that even if various pipes need to be bent to intersect with the axis of the ventilation duct in the longitudinal direction, there is no need to pass between the end surface of the outlet of the ventilation duct and the rain cover Since it is bent, it is possible to avoid a decrease in circulation efficiency when air circulates in the ventilation duct.

In addition, if the connection part of the auxiliary pipe connected to the ventilation pipe is made to have a cross-section with a different diameter, even if the piping hole for passing the ventilation pipe is small, a small ventilation pipe must be used. , and there is no need to prepare additional auxiliary pipelines.

In addition, if the opening of the outlet-side end of the above-mentioned auxiliary pipeline is cut obliquely, it has the following advantages, that is, when it is led out to the rainproof cover provided for preventing rain, even if the outlet-side end of the ventilation pipeline is in contact with the rainproof cover The wall contact will not hinder the circulation of air.
