[0027]
In the above configuration, when performing the drying operation of the clothes in the bathroom B, when the drying operation switch (not shown) of the operation unit 80 is turned on, the control device 30 receives the operation signal and receives the heat source from the control device 30. An operation command is output to the heat pump (not shown), the circulation motor (not shown), and the exhaust motor 44, and the heat source device (not shown) is operated. The air in the bathroom B passes through the heat exchange section 18 from the suction port 34 provided in the decorative board 36 by being supplied and driving the circulation motor (not shown) to rotate the circulation impeller 11. The heated air is blown out from the outlet 35 into the bathroom B as warm air, and the exhaust motor 44 is driven to rotate the exhaust impeller 42, so that the air in the bathroom B is discharged from the inlet 34. The casing 10 passes through the opening 58 provided in the casing 9 and the opening 57 provided in the casing 10 and enters the casing 10, and the air in the lavatory C is supplied to the suction port 3, the connection duct 2, and the intake connection 22 a. , And air in the toilet (not shown) enters the casing 10 through a suction port (not shown), a connection duct 2 ′, and a suction connection portion 22 b, and further, the respective air After passing through the exhaust blower casing 41, the air is discharged outside through the exhaust connection portion 21, the check valve 20, and the exhaust duct 1, and the clothes are dried.
[0028]
At this time, the check valve 20 opens the air path and forms an air flow by rotating the shielding portion 24 about a rotation shaft 25 provided on the shielding portion 24 by the pressure through which the air passes. I do.
[0029]
When the drying operation switch (not shown) of the operation unit 80 is turned off, the operation signal is received by the control device 30 and the heat source device (not shown), the circulation motor (not shown), and the exhaust When a stop command is output to the motor 44 and the heat source unit (not shown) is stopped, the supply of hot water to the heat exchange unit 18 is stopped, the circulation motor (not shown) is stopped, and the circulation impeller 11 is stopped. , The circulation of the air in the bathroom B stops, and the exhaust motor 44 stops to stop the rotation of the exhaust impeller 42, thereby stopping the discharge of air to the outside. As a result, drying of the clothes is stopped.
[0030]
At that time, the backflow prevention valve 20 loses the pressure through which the air passes, so that the shielding portion 24 rotates around the rotation shaft 25 by the weight of the blocking portion 24 to close the air passage.
[0031]
The blocking unit 24 blocks the wind from outside by being in close contact with the sealing surface 28 provided on the cylindrical unit 23, and connects to the ventilation device 47, the device body 31, the bathroom B, the washroom C, and the toilet (not shown). To prevent backflow.
[0032]
When the heating operation of the bathroom B is performed, when a heating operation switch (not shown) of the operation unit 80 is turned on, the control device 30 receives the operation signal and receives a heat source device (not shown) from the control device 30; When an operation command is output to a circulation motor (not shown) and a heat source unit (not shown) is operated, hot water is supplied from the hot water inlet pipe 19 to the heat exchange unit 18 and the circulation motor (not shown) is turned on. When the circulation impeller 11 is driven to rotate, the air in the bathroom B is heated by passing through the heat exchange unit 18 from the suction port 34 provided in the decorative board 36, and is heated as hot air from the outlet 35. The air is blown out into the bathroom B, and the interior of the bathroom B is heated.
[0033]
When performing ventilation operation of the bathroom B, the washroom C, and the toilet (not shown), when the ventilation operation switch (not shown) of the operation unit 80 is turned on, the control device 30 receives the operation signal and performs control. An operation command is output from the device 30 to the exhaust motor 44, and the exhaust motor 44 is driven to rotate the exhaust impeller 42, so that the air in the bathroom B is supplied from the suction port 34 to the opening provided in the casing 9. The air enters the casing 10 through the opening 58 provided in the casing 58 and the casing 58, and the air in the lavatory C enters the casing 10 through the suction port 3, the connection duct 2, and the suction connection section 22 a. The air in the toilet (not shown) enters the casing 10 via the suction port (not shown), the connection duct 2 ', and the intake connection portion 22b, and the air is further exhausted. After passing through the inside of the air blower casing 41, the air is discharged to the outside through the exhaust connection part 21, the check valve 20, and the exhaust duct 1, and is discharged into the bathroom B, the washroom C, and the toilet (not shown). Ventilation is provided.
[0034]
At this time, the check ring 20 is rotated by the pressure passing through the air around the rotating shaft 25 provided on the shield 24, as in the case of performing the above-described drying operation. , Open the air passage and form air flow.
[0035]
Further, when the ventilation operation is stopped, the check valve 20 is closed by the self-weight of the blocking unit 24 due to the absence of the pressure through which the air passes, as in the case of stopping the drying operation. By turning around the rotation shaft 25 and closing the air path, the blocking portion 24 is in close contact with the sealing surface 28 provided on the cylindrical portion 23, thereby blocking the wind from the outside, and the ventilation device 47, Backflow to the apparatus main body 31, the bathroom B, the washroom C, and the toilet (not shown) is prevented.
[0036]
FIG. 6 is a cross-sectional view of a check valve according to another embodiment showing an example of use of the check valve, which is an embodiment in which the check valve is attached to the intake connection portion 22a or 22b in FIG.
[0037]
As shown in FIG. 6, the check valve 20 includes a cylindrical portion 23 formed as an air passage for sending air, and a shutoff portion 24 for shutting off air. The outer periphery of the cylindrical portion 23 has a stepped shape. The small diameter is provided with a claw portion 32, and the large diameter is provided with a substantially round hole 26, 26 ', which is detachably attached to the intake connection portion 22a or 22b. ing.

By being fitted to the projected portion 27 ′, it is detachably attached.
[0039]
In the above configuration, when performing the drying operation of the clothes in the bathroom B or the ventilation operation of the bathroom B, the lavatory C, and the toilet (not shown), the check valve 20 is configured such that the shielding portion 24 is formed by the pressure through which the air passes. By rotating about a rotating shaft 25 provided in the shielding portion 24, an air passage is opened to form an air flow, and the air in the toilet C and the air in the toilet (not shown) are respectively connected to the connection duct. 2 or the connection duct 2 ′, the check valve 20, the intake connection portion 22 a or the intake connection portion 22 b, enters the casing 10, further passes through the exhaust blower casing 41, and then connects to the exhaust connection portion 21 and the exhaust duct 1. It is discharged outside through the inside.
[0040]
When the drying operation of the clothes in the bathroom B or the ventilation operation of the bathroom B, the washroom C, and the toilet (not shown) is stopped, the check valve 20 is turned off by the absence of the pressure through which the air passes. Then, the airflow path is closed by rotating about the rotation shaft 25 by the own weight of the blocking unit 24.
[0041]
The blocking section 24 is in close contact with a sealing surface 28 provided on the cylindrical section 23 to block the wind from the outside, to prevent a back wind to the washroom C and a toilet (not shown), and to prevent moisture in the bathroom. To the toilet C and the toilet (not shown).
