Is connected to the air intake duct 47 via a duct connecting member 7 having an opening 7a.

Further, in a proper place inside the washroom B and outside the toilet C, a blower operation unit (hereinafter referred to as a remote controller) 52 for controlling the ventilation operation of the bathroom A, the washroom B, and the toilet C by the indoor air conditioner 1 52 , 53, and signal lines 49, 5
0 is connected to the control unit (not shown) of the indoor air conditioner 1.

2 and 3 are cross-sectional views showing a ventilation state in the indoor air conditioner of the present invention. As shown in FIG. 2, the indoor air conditioner 1 has a configuration in which the ventilation unit 1b is fixed to the side surface of the bathroom unit 1a inserted into the opening 30 of the ceiling 10 by an appropriate method such as a screw, and the ventilation is performed with the bathroom unit 1a. The space of the unit 1b communicates with the opening 79.

The bathroom unit 1a is provided with a makeup panel 11 so as to face the inside of the bathroom A, and the makeup panel 11 is provided with a bathroom suction port 9 for sucking air in the bathroom A, A ventilation path 18 is formed from the bathroom suction port 9 to the exhaust port 39 described later via the ventilation unit 1b. A blower 3 including a motor 2 and a blower fan 12 is provided in the ventilation path 18.

A shutter 80 that opens and closes the ventilation path 18 is provided in the opening 79 that forms the ventilation path 18, and a stepping motor 81 that drives the shutter 80 is provided on the rotation axis of the shutter 80.

Further, as shown in FIG. 3, the intake duct 46
From the exhaust port 3 through the opening 6a and the ventilation unit 1b
A ventilation path 19 reaching 9 is also formed. Inside the duct connection member 6, a plate-shaped damper 82 that opens and closes by a suction force generated when the blower 3 is driven, and a screw 83 that suppresses the opening degree of the damper 82. Is provided.

Note that the intake duct 47 is also the same.
The ventilation unit 1b passes from the intake duct 47 through the opening 7a.
A ventilation path 20 is formed to reach the exhaust port 39 via the, and a damper 82 and a screw 83 are also provided inside the duct connection member 7.

The operation of the indoor air conditioner of the present invention having the configurations shown in FIGS. 1, 2 and 3 will be described in detail below.

When the ventilation operation is not performed, the shutter 80 and the damper 82 are closed, and the ventilation paths 18, 19, 20 are not formed.

Then, when the ventilation operation switch (not shown) of the remote controller 52 provided in the proper place in the washroom B or the remote controller 53 provided in the proper place outside the toilet C is turned on,
The blower 3 operates, and the air in the bathroom A, the washroom B, and the toilet C is sucked by the blower fan 12 from the bathroom suction port 9, the washroom suction port 15, and the toilet suction port 17,
The air is exhausted from the exhaust port 39 through the ventilation paths 18, 19 and 20 to the outside through the exhaust duct 51 via the duct connecting member 38.

At this time, the shutter 80 is opened by the electric signal applied to the stepping motor 81, and the damper 8 is opened.
Ventilation paths 18, 19, 20 are formed by opening 2 by the suction force generated by the blower 3.

FIG. 4 is an enlarged view of the damper 82 portion. As shown in FIG. 4, the damper 82 is opened by the suction force generated by the blower 3, but its opening is suppressed when it hits the tip portion 83a of the screw 83 incorporated in the duct connecting members 6 and 7. By changing the position of the screw 83, the tip 8
Since the position of 3a also changes, the opening degree of the damper 82 can be changed. Therefore, when it is desired to increase the ratio of the ventilation air volume of the washroom B to the total ventilation volume of the indoor air conditioner 1, the position of the screw 83 inside the duct connecting member 6 is moved to the side where the opening degree of the damper 82 is increased. On the contrary, when it is desired to reduce the proportion of the ventilation air flow in the washroom B, the position of the screw 83 inside the duct connection member 6 may be moved to the side where the opening degree of the damper 82 becomes smaller. Further, the ventilation air volume of the toilet C may be adjusted by the same adjustment method.

FIG. 5 is an enlarged view of the shutter 80 portion.
As shown in FIG. 5, since the opening degree of the shutter 80 can be freely changed by an electric signal applied to the stepping motor 81, the ratio of the ventilation air volume of the bathroom A to the total ventilation volume of the indoor air conditioner 1. The opening of the shutter 80 may be increased to increase the number of openings, and conversely, the opening of the shutter 80 may be decreased to decrease the ventilation air volume of the bathroom A.

Therefore, if the function of changing the electric signal applied to the stepping motor 81 is provided to either the remote controller 52 or 53, the ventilation air volume balance can be changed even after the indoor air conditioner 1 is installed. Become.

In addition, if the function of displaying the electric signal applied to the stepping motor 81 is added to either the remote controller 52 or 53, the ventilation air volume can be adjusted while confirming the current position of the shutter 80. Therefore, it becomes easier to change the ventilation air volume balance.

Further, as shown in FIG. 2, the air flow rate detecting means 90 is provided in the middle of the ventilation path 18, the ventilation air volume in the ventilation path 18 is measured, and the value can be displayed on either the remote controller 52 or 53. By doing so, the ventilation air volume can be adjusted while directly checking the actual ventilation air volume instead of the opening degree of the shutter 80, which makes it easier to change the ventilation air volume balance.

6 and 7 are block diagrams showing a control mode of the indoor air conditioner in the embodiment of the present invention.

As shown in FIG. 6, the air volume signal detected by the air volume detection means 90 is sent to the control section 91, and based on the signal, the control section 91 sends an operation signal to the blower 3 and the stepping motor 81. The method. As a result, the outputs of the blower 3 and the stepping motor 81 are automatically determined so that the ventilation air volume is set in advance, so that the work of changing the ventilation air volume balance can be omitted.

Further, as shown in FIG. 7, a target value input section 92 for inputting a target value of ventilation air volume is provided to either the remote controller 52 or 53, and a target value signal from the target value input section 92 is sent to the control section 91. If a control method is adopted in which an operation signal is sent to the blower 3 and the stepping motor 81 based on the target value signal and the air volume signal from the air volume detection means 90,
The operator only needs to specify the desired ventilation air volume, and the work of changing the ventilation air volume can be performed automatically, and the highly accurate ventilation air volume balance can be easily adjusted.

The above description relates to only one embodiment of the present invention, and does not mean that the present invention is limited to the above description. For example, damper 8
2 and the screw 83 may be disposed inside the toilet suction port 15 or the toilet suction port 17.

Further, the damper 82 may be structured like the shutter 80 which is driven by an electric signal.

Further, although the stepping motor 81 is used as the driving means of the shutter 80, other driving means may be used, for example, a motor capable of forward and reverse rotation is used as the shutter 8.
The same effect can be obtained even when the shutter 80 is used as a driving unit of 0 and the opening of the shutter 80 is detected by a position sensor.

Furthermore, the function of changing the electric signal applied to the stepping motor 81, the function of displaying the value of the electric signal currently applied to the stepping motor 81, the function of displaying the signal detected by the air volume detecting means 90, and the like. , Remote control 52 or 53 to input the target value of ventilation air volume
However, they may be separated from each other if necessary.
