Description

  The present invention includes an intake port for sucking indoor air, a blowout port for circulating and discharging air sucked from the intake port into the room, a suction unit for sucking the air through the intake port, and a circulation from the blowout port. The present invention relates to an air conditioner including a heater that heats exhausted air.

  A general bathroom is provided with an air conditioner for ventilating the bathroom. In recent years, there are many bathroom air conditioners that have a bathroom drying function that dries clothing by heating the air in the bathroom, as well as simply ventilating the bathroom.

In a bathroom air conditioner, a sirocco fan is often used as a fan for absorbing air in the bathroom. The sirocco fan has a structure in which air is sucked from the center of rotation to the circumferential direction by rotating a disk-shaped fan having a plurality of blades disposed on the peripheral edge. Since the bathroom air conditioner using a sirocco fan can reduce the thickness (height) of the equipment due to its structure, it is easy to design the apparatus body compactly. For this reason, the air blower using a sirocco fan has a feature that it can be easily installed on a bathroom ceiling or the like where installation space is limited (see, for example, Patent Document 1).
JP 2004-340407 A (page 4-6, FIG. 1)

  An air conditioner using a sirocco fan is characterized in that the speed of air introduced into the main body case varies depending on the thickness direction of the sirocco fan. Specifically, when a sirocco fan is installed in the main body case so that the drive part of the sirocco fan is located at the top, and the sirocco fan is rotated to suck in air from below, the sucked air is It is introduced into the main body case as a flow directed obliquely upward from the portion. Thus, the air introduced into the main body case has a tendency that the amount of air introduced on the upper side in the thickness direction of the sirocco fan is larger than the amount of air introduced on the lower side in the thickness direction.

  For this reason, there is a possibility that the air introduced into the main body case may be introduced into the heater in a state where the air flow is uneven due to the difference in the air flow introduced. In places where the wind speed of the air introduced into the heater is low, there is a problem that the temperature of the air (warm air) is heated by the heater and the temperature of the air (warm air) rises higher than in other places. In places where the wind speed is high, noise such as wind noise is generated. There was a problem that it occurred.

  This invention is made | formed in view of the said problem, and makes it a subject to provide the air conditioner which can reduce the noise in a heater and can equalize the temperature of the warm air heated.

  In order to solve the above-described problems, an air conditioner according to the present invention heats the air blown from the air outlet, the air outlet that sucks in air, the air outlet that blows air sucked from the air inlet into the room, and the air Heating means, and air blowing means for sucking air through the air inlet and blowing the sucked air to the heating means, and the heating means diffuses the air blown from the air blowing means. It has the diffusion member which ventilates to the said heating means, It is characterized by the above-mentioned.

  Moreover, the said heating means may have a heater part which heats the air ventilated by the said air blowing means, and the said diffusion member may be arrange | positioned at intervals above the said heater part.

  Further, a plurality of the heater units may be disposed in the heating unit, and an opposing space for passing the air may be formed between one adjacent heater unit and another heater unit. .

  Furthermore, a guide member that guides the air blown to the heating unit by the blowing unit to the side of the diffusion member of the air conditioner according to the present invention may be provided.

  In the air conditioner according to the present invention, since the diffusing member that diffuses the air blown out by the blowing unit is provided, the air blown out by the blowing unit can be diffused and uniformly guided to the heating unit. The unevenness of the amount of introduced air introduced into the heating means can be reduced by the diffusion of air by the diffusing member, so that the noise of the air in the heating means can be suppressed.

  In particular, since the diffusing member is disposed above the heater portion with an interval, the air diffused by the diffusing member can easily flow into the heater portion through the space between the diffusing member and the heater portion. As described above, since air easily flows into the heater part evenly, it becomes easy to equalize the air volume of the air passing through the heater part, and it is possible to suppress the temperature unevenness of the warm air heated by the heater part. .

  Furthermore, since a facing space is formed between one heater unit and the other heater unit, the air volume guided to one heater unit is different from the air volume guided to the other heater unit. In this case, air can be dispersed from one heater part to the other heater part via the facing space. For this reason, it becomes easy to make uniform the air volume of the air which passes a heater part as a whole, and it becomes possible to further suppress the temperature nonuniformity of the warm air heated by the heater part.

  Moreover, since the air volume of the air passing through the heater portion is easily uniformized, it is possible to reduce the noise of the air passing through the heating means.

  Further, since the guide member that guides the air blown by the blowing means to the heating means is provided at the side end portion of the diffusing member, the air that tries to escape sideways along the diffusing member is received by the guide member. To the department. For this reason, air can be actively sent to the end of the heater part where the amount of air flowing in is reduced, and it becomes possible to reduce temperature unevenness of the warm air warmed by the heater part and to heat the air. Efficiency can be improved.

  Furthermore, the holding strength of the diffusing member can be improved by the presence of the guide member, and the generation of noise due to the vibration of the diffusing member can be suppressed.

  Hereinafter, the case where the air conditioner according to the present invention is used as a bathroom air conditioner will be described.

The sirocco fan 9 has a plurality of blades 9b disposed on the periphery of a disk-shaped base 9a, and a rotating shaft 8a of the fan motor 8 is fixed to the center of the base 9a. When a driving force is applied to the rotating shaft 8a by driving the fan motor 8, the sirocco fan 9 rotates together with the rotating shaft 8a, and the air in front of the base 9a is moved to the side of the sirocco fan 9 via the blades 9b of the sirocco fan 9. And inhale.

  The main body case 3 is a box having an opening opened downward, and a fan storage portion 12 for installing the fan unit 2 and a damper storage portion 13 for storing the damper 4 are formed. .

  As shown in FIG. 3, the fan storage portion 12 is a substantially cylindrical recess having a diameter larger than the diameter of the sirocco fan 9, and the fan motor 8 is installed on the upper surface portion of the main body case 3. A structure in which the center of the base 9a of the sirocco fan 9 is fixed to the tip of the rotation shaft 8a by storing the sirocco fan 9 in the fan storage portion 12 with the rotation shaft 8a protruding from the opening formed at the center. It has become.

  Between the side wall surface 12 b of the fan housing portion 12 and the outer peripheral side 9 c of the sirocco fan 9, a conduction path 20 for guiding the sucked air to the damper housing portion 13 is formed.

  The damper storage portion 13 is a recess capable of rotatably storing the damper 4, and a heater 6 described later is installed below the damper storage portion 13. Further, an exhaust port 16 is provided on the side wall of the damper storage portion 13 for discharging the air guided to the damper storage portion 13 to the outside of the bathroom.

  The damper 4 has a substantially rectangular shape in a plan view, and has a gently curved shape with a central convex portion in a side view as shown in FIG. A shaft 4 a is formed at the lower end of the damper 4, and both ends of the shaft 4 a are pivotally supported on the side wall of the damper storage portion 13. Further, a rib 4b is formed on the lower surface of the damper 4, and a guide hole 4c for guiding the protruding portion 19 of the cam 18 that is rotated according to the operation mode of the bathroom air conditioner 1 is formed on the rib 4b. ing. When the cam 18 rotates, the stop position of the projection 19 changes according to the rotation angle, and the rotation angle of the damper 4 is adjusted.

  As shown in FIGS. 1 and 2, the fan cover 5 is installed so as to cover the lower surface of the main body case 3. The fan cover 5 is formed with a suction hole 5a for guiding air to the center of the sirocco fan 9, and a blowout hole 5b for circulating the air carried to the damper storage part 13 indoors. . The suction hole 5 a is a circular opening formed so as to face the front surface of the base 9 a of the sirocco fan 9, and the blowout hole 5 b is a substantially rectangular opening formed so as to face the damper storage portion 13. By installing the fan cover 5 on the lower surface of the main body case 3, the lower surface of the conduction path 20 is constituted by the fan cover 5.

  A heater 6 is installed in the blowout hole 5 b of the fan cover 5. As the heater 6, a PTC (Positive Temperature Coefficien) heater is used. The PTC heater has a resistance change characteristic in which the resistance value changes depending on the temperature. When the temperature exceeds a predetermined value (Curie temperature), the resistance value is suddenly increased to suppress the flow of electricity. The structure keeps the temperature constant.

  As shown in FIGS. 3 and 4, the heater 6 includes a pair of heater portions 41 and 42, a casing 43 in which the heater portions 41 and 42 are installed, and a diffusion member formed integrally with the casing 43. 44.

  The heater parts 41 and 42 have the long plate-shaped heat transfer member 45 having the above-described resistance change characteristic, and a plurality of heat dissipation plates 46 that release the heat of the heat transfer member 45 into the air. The heat dissipating plate 46 is installed on both sides of the heat transfer member 45 in a direction orthogonal to the longitudinal direction of the heat transfer member 45, and between the adjacent heat dissipating plate 46 and the heat dissipating plate 46. A gap through which air introduced into the heater 6 passes is formed.

  The casing 43 is a quadrangular columnar frame whose upper surface and bottom surface are released. As shown in FIGS. 3 and 4, the heater portions 41 and 42 are arranged such that the end portion of one heat radiating plate is the end portion of the other radiating plate. Is stored in the casing 43 so as to face the surface. A facing space 47 is formed between the heater portion 41 and the heater portion 42, and the gap formed in the heater portion 41 and the gap formed in the heater portion 42 are communicated via the facing space 47. Yes.

  A diffusion member support portion (guide member) 48 whose central portion extends upward is formed on the upper end surface of the casing 43, and the diffusion member 44 has a bottom surface 44a in a state orthogonal to the diffusion member support portion 48. Is installed on the diffusing member support 48 so as to face the facing space 47.

  The diffusion member 44 is disposed above the heater portions 41 and 42 with a space therebetween, and a space 60 is formed between the diffusion member 44 and the heater portions 41 and 42. Note that the height H of the diffusing member 44 is defined to be approximately equal to the width L of the heat radiating plate 46.

  As shown in FIG. 3, the heater portions 41 and 42 are arranged so as to be in a direction substantially orthogonal to the blowing direction of the sirocco fan 9 (in the direction of arrow H in FIG. 3) in plan view. Further, the diffusing member 44 is disposed substantially parallel to the longitudinal direction of the heater portions 41 and 42 (the direction of arrow I in FIG. 3).

  A front panel 7 is installed on the lower surface of the main body case 3 on which the fan cover 5 is installed. In the front panel 7, an inlet (intake port) 30 is formed at a position corresponding to the inlet hole 5 a of the fan cover 5, and an outlet 15 is formed at a position corresponding to the outlet hole 5 b of the fan cover 5. . A filter 31 for preventing dust from being sucked is detachably attached to the suction port 30. The bathroom air conditioner 1 is fixed to the ceiling surface 33 so that the main body case 3 protrudes in the direction of the ceiling, and is installed in the bathroom with only the front panel 7 exposed on the ceiling surface 33 of the bathroom.

  Next, the case where the bathroom air conditioner 1 comprised in this way operates is demonstrated.

  When operating the bathroom air conditioner 1, the user selects an operation mode by operating an operation panel 50 (see FIG. 5) installed in a dressing room in the bathroom. Specifically, a heating mode for heating the bathroom, a ventilation mode for ventilating the bathroom, a drying mode for drying clothes by placing a laundry pipe (not shown) in the bathroom as a drying room, and a cool breeze that introduces a cool breeze into the bathroom Select a mode. Further, in a building such as an apartment where ventilation for 24 hours is required, operation in the 24-hour ventilation mode is performed when the operation mode of the bathroom air conditioner 1 is not selected.

  By operating the bathroom air conditioner 1 in the heating mode, the interior of the bathroom can be preheated (so-called preheating), so that the bather (user) can take a comfortable bath without feeling cold at the start of the bathroom. Can be done. In addition, the bather can comfortably bathe without feeling cold even when the body is washed in a washing place by warming the bathroom by reducing the amount of warm air blown into the bathroom during bathing (so-called bath heating). be able to.

  Moreover, by operating the bathroom air conditioner 1 in the ventilation mode, it becomes possible to install laundry pipes in the bathroom and dry clothes hung in the bathroom.

  Furthermore, by operating the bathroom air conditioner 1 in the ventilation mode, moisture in the bathroom can be positively discharged to the outdoors, so that generation of mold or the like in the bathroom can be suppressed.

  Further, by operating the bathroom air conditioner 1 in the cool breeze mode, the room temperature air can be sent into the bathroom, so that the bathroom air conditioner can be used like a fan in summer and the like.

  In addition, when the operation is performed in the 24-hour ventilation mode, it is possible to efficiently discharge volatile organic compounds such as formaldehyde that may be diffused from the interior material of the building to the outdoors. This 24-hour ventilation function is required to be installed in a building having a living room.

  When the operation mode is selected by the user, the selected operation mode is transmitted to the control unit 51 installed in the bathroom air conditioner 1 as shown in FIG. The controller 51 controls the rotation angle of the cam 18 by driving the cam driving motor 52 in accordance with the selected operation mode, and adjusts the rotation position of the damper 4 to full open, half open, or full closed. To do. Further, the control unit 51 drives the fan motor 8 of the fan unit 2 to adjust the rotational speed of the sirocco fan 9 to either strong or weak according to the selected operation mode, and also turns the heater 6 on / off. Take control.

  Note that the state in which the rotational position of the damper 4 is fully closed means that the air that flows through the conduction path 20 by rotating the damper 4 to a position that closes the exhaust port 16 is supplied to the outlet 15 as shown in FIG. 2 (refer to the air flow indicated by arrows A to B in FIG. 2), and the fully open state means that the damper 4 is turned to a position where the air outlet 15 is closed as shown in FIG. This means a state in which the air flowing through the conduction path 20 is guided to the exhaust port 16 (see the air flow indicated by arrows A to C in FIG. 6A), and the half-open state means the conduction path. A state in which the damper 4 is rotated to an intermediate position shown in FIG. 6B in order to guide the air flowing through both the blowout port 15 and the exhaust port 16 (an arrow in FIG. 6B). A to arrow B and arrows A to C).

  Next, the operation of the bathroom air conditioner 1 will be described separately for each operation mode.

<In the heating mode>
When the heating mode is set by the user, as shown in FIG. 2, the control unit 41 turns the damper 4 to the fully closed position, sets the rotation speed of the sirocco fan 9 to be strong, and turns the heater 6 on. Turn it on. When the rotation speed of the sirocco fan 9 is set to be strong, the air in the bathroom is sucked into the main body case 3 from the suction port 30 as the sirocco fan 9 rotates.

  The sucked air passes between the blades 9 b of the sirocco fan 9 and is guided to the conduction path 20 and then guided to the damper storage portion 13. In the damper storage part 13, since the damper 4 is rotated to the fully closed position, the exhaust port 16 is closed by the damper 4 as shown in FIG. For this reason, the air guided to the damper accommodating portion 13 changes the air flow direction downward along the lower surface 4 e of the damper 4 and flows to the heater 6.

  Here, the air introduced into the main body case 3 by the sirocco fan 9 has a tendency that the amount of air introduced on the upper side in the thickness direction of the sirocco fan 9 tends to be larger than the amount of air introduced on the lower side in the thickness direction. The air guided to the heater 6 along the damper 4 may enter the heater 6 in a state where the air volume is uneven.

  However, since the diffusion member 44 is formed in the heater 6, as shown in FIG. 7, the airflow guided to the heater 6 can be diffused by the diffusion member 44, and the diffused airflow is positively The other airflow can be led to the other heater part (in the direction of arrow E in the figure). In this way, the airflow that may cause a deviation in the air volume can be actively diffused by the diffusion member 44 and guided to the heater 6 in a state where the airflow is rectified, so that noise of air introduced into the heater 6 can be reduced. Can be suppressed.

  In particular, by diffusing air with the diffusing member 44, it is possible to prevent air with a high wind speed from flowing into only one heater section 41 along the damper 4, so the amount of air flow introduced into the heater 6 Can be reduced as a whole.

  Further, since the space 60 is formed between the diffusion member 44 and the heater portions 41 and 42, the air diffused by the diffusion member 44 easily spreads from one side of the diffusion member 44 to the other through the space 60. Become. For this reason, it is possible to guide the air volume diffused by the diffusing member 44 to the heater portions 41 and 42 evenly through the space 60.

  The air introduced into the heater 6 flows to the outlet 15 through a gap formed between the heat radiating plate 46 and the heat radiating plate 46. At this time, since the heat of the heat transfer member 45 is released by the heat radiating plate 46, the air passing through the gap is heated by the heat radiating plate 46 and becomes warm air.

  In addition, a facing space 47 is formed between the heater portion 41 and the heater portion 42, and the gap formed in the heater portion 41 and the gap formed in the heater portion 42 are communicated via the facing space 47. Therefore, when the air volume passing through the gap between one heater section 41 and the air volume passing through the gap between the other heater sections 42 are different, the air having a large air volume passes through the facing space 47 and is opposed. Will flow into the gap (arrow F in the figure). For this reason, it becomes easy to equalize the air volume of the air passing through the gap, and it is possible to suppress temperature unevenness of the warm air heated by the heater 6.

  In addition, since the air volume of the air passing through the gap is easily made uniform, it is possible to make it difficult to generate noise of the air passing through the gap.

  Further, since the diffusing member 44 is installed at a position where the bottom surface 44a faces the facing space 47, the air diffused by the diffusing member 44 does not directly enter the facing space 47 but is guided to the gap between the heater portions 41 and 42. It will be. Since the air rectified in this way is guided to the gap, the heating efficiency of the heater 6 can be improved.

  Further, since the diffusing member 44 is installed in the casing 43 via the diffusing member support portion 48, it is possible to improve the holding strength of the diffusing member 44 and reduce the vibration of the diffusing member 44 due to the influence of the airflow, Generation | occurrence | production of the noise (what is called a tingling sound) etc. accompanying vibration can be suppressed.

  Further, since the diffusing member 44 is installed on the diffusing member support portion 48 in a state orthogonal to the diffusing member support portion 48, the air that escapes in the lateral direction (long direction) along the diffusing member 44 is diffused. The member support 48 can be received on the side of the casing and guided to the corners 49 of the heaters 41 and 42. For this reason, since air can be actively sent to the corners 49 of the heaters 41 and 42 where the amount of inflow air flows is reduced, it is possible to reduce the temperature unevenness of the warm air heated by the heater 6. At the same time, the heating efficiency of air can be improved.

  Further, since the height H of the diffusing member 44 is substantially equal to the width L of the heat radiating plate 46, it is possible to perform rectification without hindering the flow of air introduced into the heater 6 by the diffusing member 44. Become.

  In this way, the bathroom air conditioner 1 circulates the air introduced into the heater 6 into the bathroom by warming the air introduced into the heater 6 into warm air with uniform air volume and temperature.

<Ventilation mode and 24-hour ventilation>
When the ventilation mode is set by the user, the control unit 41 rotates the damper 4 to the fully open position and sets the rotation speed of the sirocco fan 9 to be strong as shown in FIG. Set 6 to OFF. When the rotation speed of the sirocco fan 9 is set to be strong, air in the bathroom is sucked into the main body case 3 through the suction port 30 as the sirocco fan 9 rotates.

  The sucked air passes between the blades 9 b of the sirocco fan 9 and is guided to the conduction path 20 and is guided to the damper storage portion 13.

  In the damper storage part 13, since the damper 4 is rotated to the fully open position, as shown in FIG. 6 (a), the tip of the damper 4 abuts on the fan cover 5, and the damper 4 closes the air outlet 15. It will be in the state. For this reason, the air led to the damper housing part 13 flows into the space on the upper surface 4d side of the damper 4 and is discharged from the exhaust port 16 to the outside of the bathroom.

  In addition, when performing ventilation for 24 hours, while the control part 41 rotates the damper 4 to a full open position, the rotational speed of the sirocco fan 9 is set to weak, and the heater 6 is turned off. In the 24-hour ventilation mode, there is a difference that the wind speed of the air introduced into the main body case 3 becomes weak, but air is sucked and discharged through the same route as that in the ventilation mode described above.

<Dry mode and cool breeze mode>
When the user sets the drying mode, as shown in FIG. 6B, the control unit 41 rotates the damper 4 to the half-open position and sets the rotation speed of the sirocco fan 9 to be strong. Set 6 to ON. When the rotation speed of the sirocco fan 9 is set to be strong, air in the bathroom is sucked into the main body case 3 through the suction port 30 as the sirocco fan 9 rotates.

  The sucked air passes between the blades 9 b of the sirocco fan 9 and is guided to the conduction path 20 and then guided to the damper storage portion 13.

  In the damper storage part 13, the damper 4 is rotated to the half-open position, so that the air guided to the damper storage part 13 is split up and down at the tip of the damper 4. The air that has flowed to the upper surface 4d side of the damper 4 is guided toward the exhaust port 16 along the upper surface 4d of the damper 4 as already described in the case of the ventilation mode and the 24-hour ventilation.

  Further, the air flowing toward the lower surface 4e of the damper is guided to the heater 6 along the lower surface 4e of the damper 4 as already described in the heating mode.

  Since the diffusion member 44 is formed in the heater 6, the airflow introduced into the heater 6 can be diffused by the diffusion member 44 to be guided to the heater 6 while reducing the deviation of the air volume, and is introduced into the heater 6. It is possible to suppress air noise.

  In particular, by diffusing air with the diffusing member 44, it is possible to prevent air with a high wind speed from flowing into only one heater section 41, so that the bias of the air volume introduced into the heater 6 is totally reduced. It is possible to reduce it.

  Further, since the space 60 is formed between the diffusion member 44 and the heater portions 41 and 42, the air diffused by the diffusion member 44 easily spreads from one side of the diffusion member 44 to the other through the space 60. Become. For this reason, it is possible to guide the air volume diffused by the diffusing member 44 to the heater portions 41 and 42 evenly through the space 60.

  Further, since the gap formed in the heater portion 41 and the gap formed in the heater portion 42 communicate with each other via the facing space 47, the air passing through the gap is transferred to another gap via the facing space 47. It becomes easy to equalize the air volume of the air passing through the gap. Thus, since the air volume of air is made uniform, it becomes possible to suppress temperature unevenness of warm air heated by the heater 6.

  Furthermore, since the air volume of the air passing through the gap is easily uniformed, it is possible to make it difficult to generate noise of the air passing through the gap.

  Further, since the diffusing member 44 is installed at a position where the bottom surface 44a faces the opposing space 47, the air diverted by the diffusing member 44 does not directly enter the opposing space 47 but is guided to the gap between the heater portions 41 and 42. As a result, the heating efficiency of the heater 6 can be improved.

  Further, since the diffusing member 44 is provided in the casing 43 via the diffusing member support portion 48, the holding strength of the diffusing member 44 can be improved, and vibration of the diffusing member 44 due to airflow resistance or the like can be prevented and vibration can be generated. Generation of the accompanying noise can be suppressed.

  Further, since the diffusing member 44 is installed on the diffusing member supporting portion in a state orthogonal to the diffusing member supporting portion 48, the diffusing member supporting portion 48 causes the casing 43 Can be received and guided to the corners of the heater portions 41 and 42. For this reason, air can be actively sent to the corners 49 of the heaters 41 and 42 where the amount of air inflowing air is reduced, and it is possible to reduce the temperature unevenness of the warm air heated by the heater 6. The air heating efficiency can be improved.

  Further, since the height of the diffusion member 44 is substantially equal to the width of the heat radiating plate 46, rectification can be performed without hindering the flow of air introduced into the heater 6 by the diffusion member 44.

  In this way, the bathroom air conditioner 1 warms the air introduced into the heater 6 to warm air with uniform air volume and temperature and circulates it in the bathroom.

  When the cool air mode is selected by the user, the setting of the rotational position of the damper 4 and the rotational speed of the sirocco fan 9 is the same setting as in the drying mode, except that the heater 6 is set to OFF. For this reason, even when the cool air mode is selected, the air introduced into the heater 6 is diffused by the diffusion member 44 in the same manner as in the drying mode described above, so that the air is uniformly distributed to the heater 6. As a result, noise can be reduced.

  As mentioned above, although embodiment of the bathroom air conditioner 1 was divided and demonstrated for every operation mode, the air conditioner which concerns on this invention is not limited to embodiment mentioned above. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, since the diffusion member only needs to be formed at a position where the bottom surface faces the opposing space, the upper end of the diffusion member may be bent in the air inflow direction. Further, the air flow may be diffused by the shape of the upper end of the diffusing member, and the shape is other than the shape shown in FIGS. 4A and 4B in the embodiment. There may be. By bending the tip or making it in another shape in this way, air turbulence at the tip of the diffusion member 44 can be suppressed, and noise such as wind noise can be further reduced.

  In the above-described embodiment, the configuration in which the diffusing member 44 is installed on the diffusing member support 48 in a state orthogonal to the diffusing member support 48 has been described. However, the diffusing member 44 is not necessarily provided on the diffusing member support 48. It is not limited to what is orthogonal. If the structure is such that the diffusing member support 48 can receive the air to escape laterally along the diffusing member 44 at the side of the casing 43 and guide it to the corners of the heaters 41, 42. The diffusing member 44 may be obliquely attached to the diffusing member support portion 48, or may have another configuration.

  Furthermore, in the above-described embodiment, the case where the sirocco fan 9 is used as a unit with the fan motor 8 is described. However, the fan is not necessarily limited to a unitized one. A fan, a motor, etc. may be comprised separately. Furthermore, in the embodiment, the case where a sirocco fan is used as a fan for blowing air has been described. However, the fan is not necessarily limited to a sirocco fan, and a multi-blade fan such as a radial fan is used. May be.

  In the above embodiment, the air conditioner that performs ventilation (circulation) and exhaust of air using one fan unit has been described. However, both the fan unit for ventilation and the fan unit for exhaust are provided.
