  In addition, when attaching the main body case 5 via the spacer member 7, the process of forming the opening 52 etc. in the wall 51 is the same as the form which attaches the main body case 5 directly.

  First, in order to attach the spacer member 7 to the main body case 5, the main body case 5 is fitted into the opening 7 a of the spacer member 7, and the mounting flange portion 8 of the main body case 5 is abutted against the flange receiving portion 12 of the spacer member 7.

  Next, the screw 11b is passed through the main body mounting hole 9 of the mounting flange portion 8 and the screw 11b is tightened into the screw hole 13 of the spacer member 7, so that the spacer member 7 is connected to the back side of the mounting flange portion 8 of the main body case 5 with the screw 11b. To fix.

  Next, the main body case 5 to which the spacer member 7 is attached is fitted into the opening 52 of the wall 51, and the screw 11 a is passed through the spacer mounting hole 14 of the spacer member 7 from the guide hole 10 of the mounting flange portion 8. By tightening to 51, the main body case 5 is fixed to the wall 51 with the screw 11a through the spacer member 7.

  Then, the front panel 6 is attached to the main body case 5. An outdoor hood 56 is attached to the air supply duct 54 and the exhaust duct 55.

  Here, the spacer mounting hole 14 of the spacer member 7 includes a guide tube portion 14 a connected to the guide hole 10 of the mounting flange portion 8. Thereby, when the screw 11a is inserted into the spacer mounting hole 14 located on the back side of the spacer member 7 from the guide hole 10 of the mounting flange portion 8, the screw 11a can be prevented from dropping and the screw 11a can be easily inserted. Can do.

  When the dimension between the wall 51 and the outer wall 53a is shallow, the entire body case 5 cannot be embedded in the wall 51, so that the body case 5 is attached to the wall 51 via the spacer member 7. Thus, the main body case 5 is floated from the wall 51 in accordance with the thickness of the spacer member 7. Thereby, a part of the back side of the main body case 5 is embedded in the wall 51, and the front panel 6 and the spacer member 7 are exposed from the wall 51 to the room side.

  Therefore, even when the dimension between the wall 51 and the outer wall 53a is shallow and the entire body case 5 cannot be embedded inside the wall 51, the body case 5 is not exposed and heat exchange is performed without impairing the appearance. A mold ventilator 1 can be installed.

  And since the difference in the dimension between the wall 51 and the outer wall 53a can be dealt with whether or not the spacer member 7 is attached, it becomes possible to deal with one type of device, the cost can be reduced, and the attachment method is also the same. Therefore, workability can be improved.

  Further, the outer shape of the spacer member 7 is slightly smaller than the outer shape of the front panel 6, so that when the heat exchange ventilator 1 attached to the wall 51 through the spacer member 7 is viewed, the heat exchange ventilator An effect of making it visually inconspicuous can be obtained by forming a shadow on one side surface.

<Operation example of heat exchange type ventilator>
Next, the operation of the heat exchange type ventilator 1 attached to the wall 51 as described above will be described with reference to each drawing. During the ventilation operation, the air inlet shutter 43 opens the air supply fan intake port 20a, and the exhaust port shutter 44 opens the exhaust port 31.

  In the heat exchanging ventilator 1, when the fan motor 18 is rotationally driven in response to an operation at an operation unit (not shown), the impeller 19 of the supply fan 2 and the impeller 21 of the exhaust fan 3 rotate.

  When the impeller 19 of the air supply fan 2 rotates, outdoor air (outside air OA) is sucked from the air supply fan suction port 20a on the back side of the main body case 5 through the air supply duct 54. The outside air sucked from the air supply fan inlet 20a passes through the air supply fan case 20 and blows out from the air supply fan outlet 20b to the air supply filter attachment air passage 27.

  The outside air blown out to the air supply filter mounting air passage 27 passes through the air supply filter 33, passes through the air supply inflow portion 24 a of the heat exchange element 4, passes through the air supply air passage 4 a, and communicates from the air supply outflow portion 24 b with the air supply opening communication Blow out on the road 28.

  Then, the outside air blown out to the air inlet communication passage 28 is blown out into the room as the air supply SA from the air outlet 15 of the front panel 6.

  When the impeller 21 of the exhaust fan 3 rotates, indoor air RA is sucked from the exhaust fan suction port 22a through the suction port 16 of the front panel 6. The indoor air sucked from the exhaust fan inlet 22a passes through the exhaust fan case 22 and blows out from the exhaust fan outlet 22b to the exhaust filter attachment air passage 29.

  The room air blown out to the exhaust filter attachment air passage 29 passes through the exhaust filter 34, passes through the exhaust air inlet 25 a of the heat exchange element 4, passes through the exhaust air passage 4 b, and then goes from the exhaust air outlet 25 b to the exhaust port communication air passage 30. Blow out.

  Then, the room air blown out to the exhaust port communication air passage 30 is discharged from the exhaust port 31 on the back side of the main body case 5 to the outside as an exhaust gas EA through the exhaust duct 55.

  Now, the air in the air-conditioned room has a lower temperature than the outside air in summer and a higher temperature than the outside air in winter. In the heat exchanging element 4, heat is exchanged between the outside air passing through the supply air passage 4a and the indoor air passing through the exhaust air passage 4b, so that in summer, between the high temperature outside air and the cooled indoor air. Heat exchange is performed and the temperature of the outside air is lowered. In winter, heat is exchanged between the low-temperature outside air and the heated indoor air, and the temperature of the outside air is raised.

  Thereby, in the heat exchange type | mold ventilation apparatus 1, indoor ventilation can be performed, supplying outside air close | similar to indoor temperature. And the room 61 shown in FIG. 11 in which the heat exchange type ventilation apparatus 1 is installed is provided with an air volume that satisfies the predetermined ventilation frequency, whereby the room 61 is ventilated for 24 hours. The heat exchange element 4 may be a total heat exchange element that can exchange both temperature and humidity.

  When the heat exchange type ventilator 1 is used in summer or the like, foreign matter such as insects may enter the outside air sucked by the air supply fan 2. In the heat exchange type ventilator 1, foreign matter in the outside air is captured by the air supply filter 33 so as not to enter the air supply air passage 4 a of the heat exchange element 4.

  Since the foreign matter captured by the air supply filter 33 becomes clogged when it is attached to the filter portion 35, the foreign matter attached to the filter portion 35 is dropped downward by placing the filter portion 35 at an angle.

  As described above, the heat exchange element 4 has the inflow portion and the outflow portion inclined at 45 degrees when viewed from the front, and the air supply inflow portion 24a is positioned on the lower side. The filter 33 can be disposed at the inlet of the supply air inflow portion 24a of the heat exchange element 4 with the filter portion 35 inclined downward with respect to the air flow E shown in FIG.

  Thereby, in the air supply filter 33, the foreign matter adhering to the filter part 35 can be dropped down, the occurrence of clogging of the filter part 35 in a short period can be prevented, and the air path resistance can be reduced to increase the efficiency. it can.

  The air supply filter 33 is provided with a bug collecting plate 37 below the inclined filter unit 35, and foreign matter that has fallen from the filter unit 35 is collected by the insect collecting plate 37 and enters the air supply filter mounting air passage 27. There is no direct fall.

  Further, the insect collecting plate portion 37 is a flap portion 39 provided to prevent the fall of foreign matter or the like, and by forming an air passage through which air flows, the air passage resistance can be reduced and the efficiency can be increased. it can.

  Here, since the indoor air passes through the exhaust filter 34, there is little adhesion of foreign matters such as insects. Therefore, the structure for removing the adhering foreign matter, such as the air supply filter 33, is not particularly required.

  In addition, since the air supply filter 33 and the exhaust filter 34 may be clogged with dust or the like due to long-term use of the heat exchange type ventilator 1, regular replacement is necessary. In the heat exchange type ventilator 1 of this example, the air supply filter 33 is supported by the air supply filter guide member 41 so as to be slidable in the front-rear direction along the extending direction of the heat exchange element 4.

  Thereby, the air supply filter 33 is detachably attached from the front side of the main body case 5 by sliding back and forth along the extending direction of the heat exchange element 4.

  The air supply filter 33 is pulled out integrally with the insect collecting plate portion 37, and the insect collecting plate portion 37 is raised by the side guide 38 and the flap portion 39, so that foreign matter falls outside when being pulled out. Is preventing.

  The exhaust filter 34 is supported by the exhaust filter guide member 42 so as to be slidable in the front-rear direction along the extending direction of the heat exchange element 4. Thereby, the exhaust filter 34 is detachably attached from the front side of the main body case 5 by sliding it back and forth along the extending direction of the heat exchange element 4. Accordingly, the exhaust filter 34 is detachably attached to the inlet of the exhaust inflow portion 25a located on the upper side with respect to the heat exchange element 4 in which each inflow portion and outflow portion are inclined at 45 degrees when viewed from the front. Can be arranged.

  In this manner, by allowing the air supply filter 33 and the exhaust filter 34 to be attached and detached from the front side of the main body case 5, as shown in FIG. It can be set as the structure which can replace | exchange the air supply filter 33 and the exhaust filter 34. FIG.

  When the heat exchange type ventilator 1 is used in winter or the like, condensation may occur in the heat exchange element 4 due to a temperature difference between the outside air and the room air. That is, the indoor air passing through the exhaust air passage 4b of the heat exchange element 4 is cooled by the outside air passing through the supply air passage 4a, so that condensation mainly occurs in the exhaust air passage 4b.

  In the heat exchange type ventilator 1 of this example, the heat exchange element 4 is inclined at 45 degrees, and the supply air passage 4a and the exhaust air passage 4b are inclined. Thereby, the dew condensation water which generate | occur | produced in the exhaust air path 4b flows to the exhaust port communication air path 30 direction by the inclination of the exhaust air path 4b.

  The exhaust port communication air passage 30 is provided with a drain pan 32, and condensed water generated in the exhaust air passage 4 b of the heat exchange element 4 is collected by the drain pan 32. The condensed water collected by the drain pan 32 is drained to the outside from the exhaust port 31 through the exhaust duct 55 due to the inclination of the drain pan 32.

  In the heat exchange type ventilator 1 of the present example, the inlet of the exhaust inflow portion 25a positioned on the upper side with respect to the heat exchange element 4 in which each inflow portion and outflow portion are inclined at 45 degrees when viewed from the front. The exhaust filter 34 is detachably disposed.

  Thus, the exhaust outlet 25b of the heat exchange element 4 where the exhaust filter 34 is not disposed is positioned on the lower side, and the exhaust port communication air passage 30 communicating with the exhaust outlet 25b is disposed on the lower side of the main body case 5. Can do. Thus, the dew condensation water generated in the heat exchange element 4 can be collected in the drain pan 32 by arranging the exhaust filter 34 on the upper side. Then, the dew condensation water can be drained to the outside through the exhaust port 31 communicating with the exhaust port communication air passage 30.

<Operation example of shutter>
