  The heat exchange element 7 is provided in the main body case 2 at a position where the air supply path 13 and the exhaust path 14 intersect. The heat exchange element 7 exchanges heat between the air supplied into the room and the air discharged to the outside.

  The main body case 2 is installed with the first side surface 8 up (top surface) and the second side surface 9 down (bottom surface). That is, the indoor suction port 3, the exhaust port 4, the outside air suction port 5, and the air supply port 6 are provided on the upper surface of the main body case 2. Accordingly, air is sucked from the upper part of the main body case 2 and blown out from the upper part of the main body case 2.

  With such a configuration, the workability at the time of product installation can be improved.

  Furthermore, as shown in FIG. 3, the air supply fan 10 and the exhaust fan 11 may be provided above the heat exchange element 7. That is, the air supply fan 10 and the exhaust fan 11 may be provided closer to the first side surface 8 than the heat exchange element 7.

  Moreover, the structure of providing the humidification unit 15 connected to the air supply opening 6 may be sufficient.

  Hereinafter, the humidifying unit 15 will be described in detail with reference to FIGS. 4 and 5.

  The humidifying unit 15 has an inlet 16, an outlet 17 and a humidifying unit 30.

  The inlet 16 is provided, for example, on the side of the humidifying unit case 37 and communicates with the air supply port 6.

  The outlet 17 is provided, for example, in the upper part of the humidifying unit case 37, and supplies the air humidified by the humidifying unit 30 into the room.

  The humidifying unit 30 has a blowing up air passage 34, a bottom 35, a humidifying unit outlet 36, and a humidifying unit case 37.

  The humidifying part case 37 has, for example, a cylindrical shape.

  The humidifying unit 30 humidifies the air sucked from the inlet 16.

  In addition, the humidifying unit 30 may include a centrifugal crushing unit 60. At this time, the humidifying part case 37 incorporates the centrifugal crushing part 60 partitioned by the inner wall 32.

  The centrifugal crushing unit 60 includes, for example, a pumping pipe 61, a centrifugal crushing disk 62, and a crushing motor 63.

  The pumping pipe 61 is rotated based on the operation of the crushing motor 63 to wind up the water stored in the bottom portion 35.

  The centrifugal crushing disc 62 breaks up the water wound up by the pumping pipe 61. Air droplets passing through the centrifugal crushing unit 60 are humidified by the water droplets crushed by the centrifugal crushing disc 62.

  The blow-up air passage 34 is a region partitioned by the inner wall 32 and the side surface of the humidifying unit case 37, and the air humidified by the centrifugal crushing unit 60 passes through. The air passing through the upwind air path 34 is blown out from the centrifugal crushing section 60 toward the bottom 35 and then blown toward the outlet 17.

  The bottom portion 35 has a function as a water storage portion in which water for humidification is stored. In the humidifying part case 37, the bottom part 35 is provided below the centrifugal crushing part 60.

  The humidifying part drainage port 36 is provided in the bottom part 35, and communicates with the humidifying part drainage path 38 (see FIG. 8). After the operation of the humidifying unit 15 is finished, the water accumulated in the bottom portion 35 is drained from the humidifying portion drain 36 as the drainage 44 from the humidifying portion. The drainage 44 from the humidifying part is drained to the outside from the humidifying part outlet 36 through the humidifying part drain 38.

  Here, the flow of air in the humidifying unit 15 will be described.

  First, the air blown out from the air supply port 6 of the main body case 2 flows into the humidifying part case 37 from the inflow port 16. The air drawn in from the inlet 16 is humidified by the centrifugal crushing unit 60. The air humidified by the centrifugal crushing unit 60 is blown toward the bottom 35, and then supplied to the room from the outlet 17 through the upstream air passage 34.

  With this configuration, the room can be humidified by humidifying the outside air supplied from the outlet 17 into the room. In addition, since the moisture generated in the humidifying unit 30 falls to the bottom 35 by gravity, it is possible to obtain an effect that it is difficult for the heat exchange element 7 to flow back to the heat exchange type ventilation device 1 and the water to be applied to the heat exchange element 7.

  In addition, although the method of centrifuging and humidifying water was demonstrated as a humidification method by the humidification part 30, the humidification method is not restricted to this.

  Further, a solenoid valve (not shown) or the like controlled by the control unit 18 may be provided in the humidifying unit drain 36, for example, to switch between water storage and drainage. That is, when the humidifying unit 15 is operated, the solenoid valve may be closed and the water may be stored, and when the water accumulated in the bottom 35 may be drained, the solenoid valve may be opened and the humidifying unit drain 36 may be drained. Thereby, when storing water becomes unnecessary in the bottom part 35, it can drain rapidly.

  In addition, the humidifying unit 15 may be removable from the main body case 2. Thereby, the presence or absence of a humidification unit can be selected as needed. Therefore, when the humidifying unit is not provided, space saving can be achieved as compared with the case where the humidifying unit and the main body case are integrated (impossible to be removed).

  The humidifying unit 15 may be attached to the upper portion or the side portion of the main body case 2.

Second Embodiment
As shown in FIG. 5, the outlet 17 of the humidifying unit may be configured to be provided on the upper side of the humidifying unit case 37. That is, the blowing air from the humidifying unit 15 may be blown out in the lateral direction. According to this configuration, in the narrow space where the heat exchange type ventilation device 1 is installed, the blowing direction of the air supply duct can be selected to be either upward or lateral, and the workability can be further improved.

Third Embodiment
In addition, the humidifying unit 15 may include the heating unit 40 on the upstream side of the humidifying unit 30. The heating unit 40 heats the air sucked from the inlet 16, and the humidifying unit 30 located downstream of the heating unit 40 humidifies the air heated by the heating unit 40.

  By providing the heating unit 40 on the upstream side and the humidifying unit 30 on the downstream side of the humidifying unit 15, the air to be humidified can be heated in advance to efficiently humidify the room.

  Here, the heating unit 40 will be described with reference to FIG.

  As shown in FIG. 6, the heating unit 40 includes a heating member 41 and an inclined member 42.

  For example, a radiator or a heater may be used as the heating member 41. When a radiator is used, the radiator may be connected to a hot water pipe (hot water supply pipe) for floor heating, for example, and hot water may flow in the pipe of the radiator to heat the air passing through the heating unit 40. Thereby, air can be heated using the existing heat source effectively.

  In addition, cold water may be allowed to flow into the pipe of the radiator. Thus, the air passing through the heating unit 40 can condense the radiator and dehumidify the air supplied into the room. That is, the humidifying unit 15 can have a function as a dehumidifier.

  The condensed water 43 shown in FIG. 5 is the condensed water generated when cold water flows in the pipe of the radiator.

  The inclined member 42 is provided downstream of the inlet 16 and upstream of the heating member 41. Further, the inclination member 42 is inclined downward from the inflow port 16 toward the humidifying unit 30 side. That is, the inlet 16 side is high, and the humidification part 30 side is low. At this time, since the condensed water 43 generated by the heating member 41 is guided by the inclined member 42 toward the humidifying unit 30, particularly the bottom 35, it flows back to the heat exchange type ventilator 1 and water is applied to the heat exchange element 7. It is possible to obtain the effect of difficulty.

  In addition, the shape of the inclination member 42 is not restricted to what is shown in FIG.5 and FIG.6, In order to suppress the backflow to the heat exchange type ventilator 1, suppose that it can set suitably.
