Description

  The present invention relates to a blower device having a fan case base portion on which a motor for rotating a fan is installed and a fan case main body portion placed on the fan case base portion so as to contain the fan.

  A general bathroom is provided with a bathroom air conditioner (blower) for ventilating the bathroom. In recent years, bathroom air conditioners have been used not only to ventilate bathrooms but also to ensure ventilation functions in buildings.

  The bathroom air conditioner includes a main body case, a sirocco fan (multi-blade fan) for inhaling air in the bathroom, a fan motor for rotating the sirocco fan, a fan case base where the fan motor is installed, a motor And a fan case main body mounted on the fan case base so as to include a sirocco fan pivotally supported on the fan case.

  The sirocco fan is a disk-shaped rotary fan in which a plurality of blades are disposed at the peripheral edge. The sirocco fan is rotatably installed in a fan case formed by a fan case main body and a fan case base. When the sirocco fan rotates, air is sucked into the fan case through a suction opening formed in the fan case main body.

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 is easy to install 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)

  However, as described above, the fan case that houses the sirocco fan is formed by two members, the fan case main body and the fan case base, and the end of the fan case main body is brought into contact with the fan case base. It is comprised by making it fix. For this reason, if a slight distortion occurs during molding of the fan case body and the fan case base, or if the contact part is displaced due to temperature change or aging, the contact between the fan body case and the fan base case There is a possibility that the adhesion of the contact portion may be impaired.

  In particular, since a fan motor is installed to rotate the sirocco fan with respect to the fan case base, the fan case base slightly bends due to the weight of the fan motor, and the fan main body case and the fan base case are in contact with each other. There was a risk that a gap would occur at the contact portion.

  As described above, when the adhesiveness of the contact portion between the fan case main body and the fan case base is impaired and a gap is generated in the contact portion between the fan case main body and the fan case base, air leaks from the gap. There has been a problem that noise such as whistling and wind noise may occur.

  Even when there is no gap, vibration is generated in the fan case main body or the fan case base due to air pulsation caused by the rotation of the sirocco fan or driving of the fan motor. There is a problem that noise such as vibration noise may be generated in the entire case through the contact portion between the fan case main body and the fan case base and transmitted to the entire fan case.

  The present invention has been made in view of the above-described problem, and can prevent generation of a gap and vibration transmission in a contact portion between the fan case main body and the fan case base, thereby suppressing noise in the fan case. It is an object to provide a blower that can be used.

  In order to solve the above-described problems, a blower according to the present invention includes a fan case base in which a fan motor for rotating a fan is installed and the fan installed above the fan motor. A fan case main body portion mounted on the fan case base portion, and the fan case main body portion is attached to the fan case base portion with an elastic member interposed at a contact portion with the fan case base portion. It is characterized by that.

  The fan case body may be suspended from the upper surface of a body case that houses the fan case body and the fan case base.

  Further, a second fan motor for rotating another fan installed below is provided at the fan case base, and the indoor air is sucked by one fan and blown into the room, and the other fan is blown out. Indoor air may be sucked in by a fan and discharged outside the room.

  According to the blower device of the present invention, the fan case main body is attached to the fan case base with the elastic member interposed at the contact portion with the fan case base relative to the fan case base on which the fan motor is installed. Therefore, for example, even if the fan case base is bent due to the weight of the fan motor provided at the fan case base, or the fan case base is slightly distorted due to changes over time, temperature deformation, etc., the fan case main body The elastic member provided on the fan case base and the contact portion expands and contracts so as to close the gap between the fan case main body portion and the fan case base, and the outflow of air from the contact portion can be prevented. For this reason, the air passing through the space (conduction path) formed by the fan case base and the fan case main body leaks outside through the clearance between the contact portions, and noise such as whistling noise and wind noise is generated. Can be prevented.

  In particular, when the fan case main body is suspended from the upper surface of the main body case, if the fan case base is bent due to the weight of the fan motor or the like, there is a gap between the fan case main body and the fan case base. Is likely to occur. For this reason, by interposing an elastic member at the contact portion between the fan case main body and the fan case base, it is possible to more effectively suppress the generation of gaps and prevent the generation of noise such as wind noise. It becomes possible.

  When not only the fan motor but also the second fan motor is installed on the fan case base, the fan case base is easily bent due to the weight of the two fan motors. For this reason, by interposing an elastic member at the contact portion between the fan case main body and the fan case base, it is possible to more effectively suppress the generation of gaps and prevent the generation of noise such as wind noise. It becomes possible.

  Furthermore, since the elastic member can also serve as a cushioning material, vibrations such as pulsation of airflow that can occur as the fan rotates from the fan case main body part to the fan case base part via the contact part. The transmission can be prevented by the elastic member. Further, it is possible to prevent the vibration accompanying the driving of the fan motor from being transmitted from the fan case base part to the fan case main body part via the contact part by the elastic member. For this reason, it is possible to prevent vibrations generated by the fan, the fan motor, and the like from being transmitted to the entire fan case via the contact portion, and it is possible to reduce the noise of the entire blower.

Moreover, it is good also as a structure which does not perform the suction of the air from another room, without providing the other room suction inlet 2c in the bathroom air conditioner 1. FIG.

  In the bathroom 43, a land pipe 53 for suspending laundry can be installed. By applying the warm air heated by the heater 18 of the bathroom air conditioner 1 to the laundry or the like hung on the land re-pipe 53, the laundry can be quickly dried.

  In addition, a bathroom door 54 is provided at the entrance of the bathroom 43, and an air inlet 54 a is formed in the lower part of the bathroom door 54. When the air in the bathroom 43 is sucked by the bathroom air conditioner 1, the air in the bathroom 42 is guided into the bathroom 43 through the air intake 54a as the air in the bathroom 43 is sucked. .

  Furthermore, an operation panel 55 for operating the bathroom air conditioner 1 is provided on the wall surface of the washroom 42. FIG. 8A shows an example of the operation panel 55. The operation panel 55 selects a display unit 55a, a heating mode button 55b for selecting a heating operation mode, a cool air mode button 55c for selecting a cool air operation mode, a ventilation mode button 55d for selecting a ventilation operation mode, and a drying operation mode. There are provided a drying mode button 55e for selecting and a 24-hour ventilation mode button 55h for selecting the 24-hour ventilation mode.

  Further, the operation panel 55 is provided with lamps 55f corresponding to the buttons 55b to 55e, for example, so that the user can confirm the selected operation mode, and corresponds to the buttons 55b to 55e of the selected operation mode. Thus, the lamp 55f is turned on. Further, a timer button 55g may be provided so that a desired operation mode can be started or ended at a set time.

  When the 24-hour ventilation mode button 55h provided on the operation panel 55 is selected, the bathroom air conditioner 1 operates in the 24-hour ventilation operation mode. In a given building, it is obliged to perform ventilation for 24 hours. In the 24-hour ventilation, it is necessary to ventilate the entire house or the volume of a predetermined area of the house by a predetermined number of ventilations (for example, 0.5 times / hour). For this reason, ventilation is performed in the building by providing the bathroom air conditioner 1 with a 24-hour ventilation operation mode.

  When the user operates the operation panel 55 to select the operation mode of the bathroom air conditioner 1, the control unit 60 in which the selected information is stored in the circuit board unit 4 as shown in FIG. Is transmitted to. The control unit 60 is configured by a CPU (Central Processing Unit), a memory, and the like. Under the control of the control unit 60, drive control of the heater 18, the ventilation fan motor 14d, the circulation fan motor 15d, and the opening / closing motor 30 is performed. Is done. The control unit 60 controls the heater 18 and the ventilation fan motor 14d according to the heating operation mode, ventilation operation mode, cool air operation mode and drying operation mode selected by the user in accordance with a program stored in a memory or the like (not shown). This is executed for the circulation fan motor 15d and the opening / closing motor 30.

  Next, operation | movement of the bathroom air conditioner 1 performed corresponding to the operation mode mentioned above is demonstrated.

<Ventilation mode / 24-hour mode>
When the user presses the ventilation mode button 55d on the operation panel 55 to select the ventilation operation mode, the control unit 60 executes a control operation in the ventilation operation mode.

  Specifically, the control unit 60 stops the circulation fan motor 15d, stops the rotation of the circulation sirocco fan 15a, and stops the heater 18. Further, the control unit 60 drives the ventilation fan motor 14d to rotate the ventilation sirocco fan 14a, and drives the opening / closing motor 30 to rotate the opening / closing shutter 33 to open the bottom opening 31.

  When the ventilation sirocco fan 14a rotates, the air in the bathroom 43 is sucked into the ventilation fan case 10 through the ventilation inlet 10f through the panel inlet 5a and the bottom opening 31 of the front panel 5.

  At the same time, the rotation of the ventilation sirocco fan 14a leads the air in the washroom 42 to the other room intake port 2c through the first other room exhaust duct 44, and the air in the toilet 41 passes through the first other room exhaust duct 44. And, it is led to the other-chamber suction port 2c through the second other-chamber exhaust duct 48, and is sucked into the ventilation fan case 10 from the ventilation suction port 10f.

  9 and 10, the air in the bathroom 43 guided through the bottom surface opening 31 is formed in the space between the outer surface of the circulation fan case 11 and the outer surface of the ventilation fan case 10 and the inner wall surface of the main body case 2. It shows a state of being led to the inside of the ventilation fan case 10 through the ventilation inlet 10f (arrow A1 in FIGS. 9 and 10). 9 and 10, the air in the toilet 42 and the toilet 41 guided through the other-room suction port 2c is connected to the outer surface of the circulation fan case 11, the outer surface of the ventilation fan case 10, and the main body case 2. The state of being led into the ventilation fan case 10 from the ventilation inlet 10f through the space between the inner wall and the inner wall surface is shown (arrow B1 in FIGS. 9 and 10).

  When the sucked air is guided to the inside of the ventilation fan case 10 by the rotation of the ventilation sirocco fan 14a, the opening / closing unit 22 is provided at the end of the fan cover 13, and the two bottom openings 31 are formed in the main body. Since it is ensured at the left and right corners of the case 2, it is possible to increase the amount of air sucked from the bathroom 43 and to ensure a sufficient amount of air sucked.

  In particular, the bottom opening 31 is formed by the opening / closing unit frame 32 so as to be located in a space (gap) provided between the main body case 2 and the circulation fan case 11 and along the outer periphery of the circulation fan case 11. In addition, since the suction opening area from the bathroom 43 can be ensured wider than before, the suction air volume from the bathroom 43 can be increased more than before.

  The air sucked into the ventilation fan case 10 is guided through the conduction path 10e formed in the ventilation fan case 10 toward the side opening 10a serving as the outlet of the conduction path 10e. The airflow passing through the conduction path 10e in the direction of the side opening 10a gradually increases the width of the passage, so that the wind speed increases.

  At this time, since the first ventilation rectification member 19a and the second ventilation rectification member 19b are provided in the conduction path 10e, the turbulence of the air flow accompanying the increase in the wind speed is prevented from occurring in the first ventilation rectification member 19a and the second ventilation rectification rectification. The current can be rectified by the member 19b, and the disturbance of the airflow in the conduction path 10e can be suppressed to achieve smooth air discharge, and the generation of noise due to the disturbance of the airflow can be suppressed.

  Further, foamed rubber 16 is provided on the entire periphery of the bottom opening peripheral portion 10 b of the ventilation fan case 10. For this reason, for example, the circulation fan case 11 is bent due to the weight of the ventilation fan motor 14d and the circulation fan motor 15d provided in the circulation fan case 11, or the circulation fan case 11 is slightly changed due to a change with time, temperature deformation, or the like. Even if there is a risk of distortion, the foamed rubber 16 provided at the contact portion between the ventilation fan case 10 and the circulation fan case 11 expands and contracts so as to close the gap between the ventilation fan case 10 and the circulation fan case 11. Thus, the outflow of air from the contact portion can be prevented. For this reason, it can prevent that the air which passes the conduction path 10e leaks out of the ventilation unit 3 from the clearance gap between contact parts, and noises, such as a whistling sound and a wind noise, generate | occur | produce.

  In particular, in the bathroom air conditioner 1, the ventilation fan case 10 is suspended so as to secure a certain space distance L from the ceiling surface at the upper end of the main body case 2, and therefore the ventilation fan motor 14d and the circulation fan motor 15d. If the circulation fan case 11 bends due to the weight, etc., a gap is likely to occur at the contact portion between the ventilation fan case 10 and the circulation fan case 11. For this reason, by attaching the foamed rubber 16 to the entire periphery of the bottom opening peripheral portion 10b of the ventilation fan case 10, the generation of gaps can be more effectively suppressed and the generation of noise such as wind noise can be prevented. Is possible.

  In addition, when the ventilation fan case 10 and the circulation fan case 11 are fixed in a state where another member such as the first floor plate portion 17a or the second floor plate portion 17b is bonded to the upper surface of the circulation fan case 11, the flexure fan case 10 is bent. The circulation fan case 11 tends to cause a gap between the circulation fan case 11 and the floor plate portions 17a and 17b or between the ventilation fan case 10 and the floor plate portions 17a and 17b. For this reason, it becomes possible to suppress generation | occurrence | production of a gap | interval effectively by interposing the foamed rubber 16 in a contact part.

  Further, in order to guide the wiring of the ventilation fan motor 14d and the like to the outside of the blower unit 3, even if the cable is intentionally passed through the contact portion between the ventilation fan case 10 and the circulation fan case 11, foamed rubber Since the gap that can be generated by the cable can be closed by the expansion / contraction of 16, the generation of the gap can be effectively suppressed.

  Further, since the foamed rubber 16 also serves as a cushioning material, vibrations such as airflow pulsation accompanying rotation of the ventilation sirocco fan 14a are transmitted from the ventilation fan case 10 to the circulation fan case 11 via the contact portion. This can be prevented by the foamed rubber 16. Furthermore, the foamed rubber 16 can prevent the vibration of the ventilation fan motor 14d from being transmitted from the circulation fan case 11 to the ventilation fan case 10 via the contact portion. For this reason, it can prevent that the vibration of the ventilation fan case 10 or the circulation fan case 11 which generate | occur | produced in the ventilation fan unit 14 is transmitted to the whole ventilation unit 3 via a contact part, and the bathroom air conditioner 1 It is possible to reduce the overall noise.

  The air led to the side opening 10a serving as the outlet of the conduction path 10e through the conduction path 10e is exhausted from the exhaust grill 50 to the outside through the exhaust duct 51 (arrow C1 in FIGS. 9 and 10). ).

  Since the air in the bathroom 43 is exhausted to the outdoors by the ventilation fan unit 14, the air in the washroom 42 is sucked from the air intake 54 a provided in the bathroom door 54. In this way, by operating the bathroom air conditioner 1 in the ventilation operation mode, steam and moisture in the bathroom 43 can be actively exhausted to the outside, so that condensation in the bathroom 43 can be suppressed, It becomes possible to suppress the occurrence of mold.

  Even when the user presses the 24-hour ventilation mode button 55h on the operation panel 55 and the bathroom air conditioner 1 performs the operation in the 24-hour operation mode, the control unit 60 is in the above-described ventilation operation mode. Similarly to the operation, the circulation fan motor 15d is stopped, the ventilation fan motor 14d is driven to rotate the ventilation sirocco fan 14a, the opening / closing motor 30 is driven to rotate the opening / closing shutter 33, and the bottom opening 31 is opened. Let

  Thus, when the control part 60 starts the operation | movement of 24 hours ventilation operation mode, air will flow like the ventilation operation mode mentioned above, and it becomes possible to ventilate a building. In addition, since air flows in the same manner as in the ventilation operation mode, the turbulence of the airflow in the main body case 2 is suppressed by the first ventilation rectification member 19a and the second ventilation rectification member 19b even when performing ventilation for 24 hours. In addition, the foamed rubber 16 can prevent the occurrence of a gap between the ventilation fan case 10 and the circulation fan case 11, and can further suppress the generation of noise.

  In the 24-hour ventilation operation mode, the ventilation fan motor 14d of the ventilation fan unit 14 is normally operated continuously to perform ventilation, but the ventilation requirement of 0.5 times / hour is set as the number of ventilations of the building. It is good also as a structure which operates the ventilation fan unit 14 intermittently so that it may satisfy | fill.

  In addition, since the 24-hour ventilation is not necessarily intended to ventilate only the bathroom 43, for example, when the bathroom air-conditioning apparatus 1 is operated in the 24-hour ventilation mode, the rotation angle of the open / close shutter 33 is decreased to the bottom surface. The opening amount of the opening 31 may be reduced. In this way, by reducing the opening amount of the bottom surface opening 31, the amount of air sucked from the other chamber through the first other chamber exhaust duct 44 and the second other chamber exhaust duct 48 than the amount of air sucked from the bathroom 43. Therefore, the ventilation efficiency of the entire building can be improved.

  Further, when the operation is performed in the 24-hour ventilation mode, since the rotation time of the ventilation sirocco fan 14a of the ventilation fan unit 14 tends to be longer regardless of day and night, noise is reduced by reducing the rotation speed of the ventilation sirocco fan 14a. It is also possible to suppress the occurrence of.

  Further, when the bathroom air conditioner 1 is provided with a plurality of other-chamber inlets 2c, an electric shutter or the like is provided in the other-chamber exhaust duct connection portion 52 or the like to change the opening of the shutter. May be. Thus, by changing the opening degree of the shutter, the amount of air sucked from other rooms can be adjusted, and the amount of air ventilated in the entire house can be kept at a predetermined amount.

<About heating mode>
When the heating mode button 55b is pressed by the user on the operation panel 55 and the heating operation mode is selected, the control unit 60 executes a control operation in the heating operation mode.

  Specifically, the control unit 60 stops the ventilation fan motor 14d to stop the rotation of the ventilation sirocco fan 14a. Further, the controller 60 drives the opening / closing motor 30 to rotate the opening / closing shutter 33 to close the bottom opening 31. Further, the control unit 60 drives the circulation fan motor 15d to rotate the circulation sirocco fan 15a and energize the heater 18.

  When the circulation sirocco fan 15a rotates, the air in the bathroom 43 is sucked from the circulation inlet 13b of the fan cover 13 through the panel inlet 5a of the front panel 5 (FIG. 11). The air sucked from the circulation inlet 13b is sucked into the circulation fan case 11 by the circulation sirocco fan 15a (arrow A2 in FIG. 11).

  The air sucked into the circulation fan case 11 is guided to the circulation guide portion 12 through a conduction path 11 e formed in the circulation fan case 11.

  At this time, since the first circulation rectification member 20a and the second circulation rectification member 20b are provided in the conduction path 11e, the turbulence of the air flow accompanying the increase in the wind speed is prevented from occurring in the first circulation rectification member 20a and the second circulation rectification member. It can be adjusted by the member 20b, and it is possible to suppress the turbulence of the airflow in the conduction path 11e to realize a smooth air discharge, and to suppress the generation of noise due to the turbulence of the airflow.

  Further, since the foamed rubber 16 is provided on the entire periphery of the bottom opening peripheral edge portion 10b of the ventilation fan case 10, the foamed rubber 16 also serves as a cushioning material, such as the pulsation of airflow caused by the rotation of the circulating sirocco fan 15a. It is possible to prevent vibrations and vibrations accompanying driving of the circulation fan motor 15d from being transmitted from the circulation fan case 11 to the ventilation fan case 10 via the contact portion. For this reason, it can prevent that the vibration which generate | occur | produced in the circulation fan case 11 is transmitted to the whole ventilation unit 3, and it becomes possible to aim at the noise reduction of the whole bathroom air conditioner 1. FIG.

  Thereafter, the air guided to the circulation guide portion 12 through the conduction path 11e is heated by the heater 18 provided in the circulation guide portion 12, and then the air outlet 13a of the fan cover 13 and the panel of the front panel 5. It blows out in the bathroom 43 through the blower outlet 5b (arrow B2 of FIG. 11).

  Thus, by operating the bathroom air conditioner 1 in the heating operation mode, it is possible to heat the bathroom 43 while circulating the air in the bathroom 43 and to raise the temperature in the bathroom. By operating the bathroom air conditioner 1 in the heating operation mode, the inside of the bathroom 43 can be warmed in advance (so-called preheating), so that the user can comfortably bathe without feeling cold at the start of bathing. It becomes possible. Also, by warming the bathroom 43 by reducing the amount of warm air blown into the bathroom 43 during bathing (so-called bath heating), the user does not feel cold even when washing the body in the bathroom wash area. You can bathe comfortably.

  In the above-described embodiment, the ventilation fan motor 14d is stopped and the ventilation sirocco fan 14a is not rotated. However, in order to exhaust air sucked from other rooms such as the washroom 42, the opening / closing shutter 33 opens the bottom surface. You may make it rotate ventilation sirocco fan 14a in the state which obstruct | occluded 31. FIG. By rotating the ventilation sirocco fan 14a with the bottom opening 31 closed, the warmed air in the bathroom 43 is less likely to be sucked in by the ventilation fan unit 14, so the warm air is discharged outside the bathroom 43 (escape) Can be prevented.

  Even when the ventilation sirocco fan 14a is rotated with the bottom opening 31 closed, at this time, the first ventilation rectification member 19a and the second ventilation rectification member 19b provided in the conduction path cause the conduction path. It is possible to achieve smooth air discharge by adjusting the turbulence of the air flow 10e, and to suppress the generation of noise due to the turbulence of the air flow.

  Furthermore, even when the ventilation sirocco fan 14a is rotated with the bottom opening 31 closed, the foamed rubber 16 is provided on the entire periphery of the bottom opening peripheral edge 10b of the ventilation fan case 10. However, it can be expanded and contracted so as to close the gap between the ventilation fan case 10 and the circulation fan case 11, and the outflow of air from the contact portion can be prevented. For this reason, it can prevent that the air which passes the conduction path 10e leaks out of the ventilation unit 3 from the clearance gap between contact parts, and noises, such as a whistling sound and a wind noise, generate | occur | produce.

  Further, since the foamed rubber 16 also serves as a cushioning material, vibration generated in the ventilation fan unit 14 can be prevented from being transmitted to the entire blower unit 3, and the entire bathroom air conditioner 1 can be silenced. It becomes possible to plan.

<Dry mode and cool breeze mode>
When the user presses the drying mode button 55e on the operation panel 55 to select the drying operation mode, the control unit 60 executes a control operation in the drying operation mode.

  Specifically, the control unit 60 drives the ventilation fan motor 14d to rotate the ventilation sirocco fan 14a. Further, the control unit 60 drives the opening / closing motor 30 to rotate the opening / closing shutter 33 to open the bottom surface opening 31. Further, the control unit 60 drives the circulation fan motor 15d to rotate the circulation sirocco fan 15a and energize the heater 18.

  When the ventilation sirocco fan 14a rotates, the air in the bathroom 43 is sucked into the ventilation fan case 10 from the ventilation inlet 10f through the panel inlet 5a and the bottom opening 31 of the front panel 5 (FIG. 12). Arrow A1).

  At the same time, the rotation of the ventilation sirocco fan 14a leads the air in the washroom 42 to the other room intake port 2c through the first other room exhaust duct 44, and the air in the toilet 41 passes through the first other room exhaust duct 44. Then, the air is guided to the other-chamber suction port 2c through the second other-chamber exhaust duct 48, and is sucked into the ventilation fan case 10 from the ventilation suction port 10f (arrow B1 in FIG. 12).

  At this time, since the opening / closing unit 22 is provided at the end of the fan cover 13 and the two bottom surface openings 31 are secured at the left and right corners of the main body case 2, the amount of air sucked from the bathroom 43 can be increased. It is possible to secure a sufficient suction air volume.

  In particular, the bottom opening 31 is formed between the main body case 2 and the circulation fan case 11 so as to be positioned in a space (gap) provided along the outer periphery of the circulation fan case 11. Since the suction opening area from can be ensured wider than before, the amount of suction air from the bathroom can be made larger than before.

  The air sucked into the ventilation fan case 10 is guided to the conduction path 10e in the ventilation fan case 10. The air velocity passing through the conduction path 10e to the side opening 10a gradually increases the width of the passage, so that the wind speed increases.

  At this time, since the first ventilation rectification member 19a and the second ventilation rectification member 19b are provided in the conduction path 10e, the turbulence of the air flow accompanying the increase in the wind speed is prevented from occurring in the first ventilation rectification member 19a and the second ventilation rectification rectification. The air can be rectified by the member 19b, and the disturbance of the airflow in the conduction path 10e can be suppressed to achieve smooth air discharge, and the generation of noise due to the disturbance of the airflow can be suppressed.

  Further, foamed rubber 16 is provided on the entire periphery of the bottom opening peripheral portion 10 b of the ventilation fan case 10. For this reason, the circulation fan case 11 is bent due to the weight of the ventilation fan motor 14d and the circulation fan motor 15d provided in the circulation fan case 11, or the circulation fan case 11 is slightly distorted due to a change with time, temperature deformation, or the like. The foamed rubber 16 provided at the contact portion between the ventilation fan case 10 and the circulation fan case 11 expands and contracts so as to close the gap between the ventilation fan case 10 and the circulation fan case 11, The outflow of air from the contact portion can be prevented. For this reason, it can be prevented that the air passing through the conduction path 10e leaks out of the blower unit 3 from the gap between the contact portions, and noise such as whistling noise and wind noise is generated.

  In particular, in the bathroom air conditioner 1, the ventilation fan case 10 is suspended so as to secure a certain space distance L from the ceiling surface at the upper end of the main body case 2, and therefore the ventilation fan motor 14d and the circulation fan motor 15d. If the circulation fan case 11 bends due to the weight, etc., a gap is likely to occur at the contact portion between the ventilation fan case 10 and the circulation fan case 11. For this reason, by attaching the foamed rubber 16 to the entire periphery of the bottom opening peripheral portion 10b of the ventilation fan case 10, the generation of gaps can be more effectively suppressed and the generation of noise such as wind noise can be prevented. Is possible.

  In addition, when the ventilation fan case 10 and the circulation fan case 11 are fixed in a state where another member such as the first floor plate portion 17a or the second floor plate portion 17b is bonded to the upper surface of the circulation fan case 11, the flexure fan case 10 is bent. The circulation fan case 11 tends to cause a gap between the circulation fan case 11 and the floor plate portions 17a and 17b or between the ventilation fan case 10 and the floor plate portions 17a and 17b. For this reason, it becomes possible to suppress generation | occurrence | production of a gap | interval effectively by interposing the foamed rubber 16 in a contact part.

  Further, even when the cable is passed through the contact portion between the ventilation fan case 10 and the circulation fan case 11 in order to guide the wiring of the ventilation fan motor 14d and the like to the outside of the blower unit 3, the expansion / contraction of the foam rubber 16 is increased. Therefore, the gap that can be generated by the cable can be closed, so that the generation of the gap can be effectively suppressed.

  In addition, since the foamed rubber 16 also serves as a cushioning material, vibrations such as pulsation of the airflow caused by the rotation of the ventilation sirocco fan 14a are transferred from the ventilation fan case 10 to the circulation fan case 11 through the contact portion. Transmission can be prevented by the foamed rubber 16. Furthermore, the foamed rubber 16 can prevent the vibration of the ventilation fan motor 14d from being transmitted from the circulation fan case 11 to the ventilation fan case 10 via the contact portion. For this reason, the foamed rubber 16 can prevent the vibration of the ventilation fan case 10 or the circulation fan case 11 generated in the ventilation fan unit 14 from being transmitted to the entire blower unit 3 through the contact portion. It is possible to reduce the noise of the entire air conditioner 1.

  Then, the air guided to the side opening 10a serving as the outlet of the conduction path 10e through the conduction path 10e is exhausted from the exhaust grill 50 to the outside through the exhaust duct 51 (arrow C1 in FIG. 12). .

  On the other hand, when the circulation sirocco fan 15 a rotates, the air in the bathroom 43 is sucked from the circulation inlet 13 b of the fan cover 13 through the panel inlet 5 a of the front panel 5. Air sucked from the circulation inlet 13b is drawn into the circulation fan case 11 by the circulation sirocco fan 15a (arrow A2 in FIG. 12).

  The air sucked into the circulation fan case 11 is guided to the circulation guide portion 12 through a conduction path 11 e formed in the circulation fan case 11.

  At this time, since the first circulation rectification member 20a and the second circulation rectification member 20b are provided in the conduction path 11e, the turbulence of the air flow accompanying the increase in the wind speed is prevented from occurring in the first circulation rectification member 20a and the second circulation rectification member. It can be adjusted by the member 20b, and it is possible to suppress the turbulence of the airflow in the conduction path 11e to realize a smooth air discharge, and to suppress the generation of noise due to the turbulence of the airflow.

  Further, since the foamed rubber 16 is provided on the entire periphery of the bottom opening peripheral edge 10b of the ventilation fan case 10, the foamed rubber 16 also serves as a cushioning material, and the vibration of the circulation fan unit 15 is caused to pass through the contact part. Thus, it is possible to prevent the circulation fan case 11 from being transmitted to the ventilation fan case 10. For this reason, it can prevent that the vibration which generate | occur | produced in the circulation fan case 11 is transmitted to the whole ventilation unit 3, and it becomes possible to aim at the noise reduction of the whole bathroom air conditioner 1. FIG.

  After that, the air guided to the circulation guide part 12 through the conduction path 11e is heated by the heater 18 provided in the circulation guide part 12, and then the air is passed through the outlet 13a and the panel outlet 5b of the front panel 5. Through the bathroom 43 (arrow B2 in FIG. 12).

  Thus, by operating the bathroom air conditioner 1 in the dry mode, the inside of the bathroom 43 can be heated by the circulation fan unit 15 while the air in the bathroom 43 is discharged to the outdoors by the ventilation fan unit 14. It becomes possible to dry clothes hung on the land pipe 53 in 43. In addition, a part of the air in the bathroom 43 is exhausted to the outside, and ventilation in the bathroom 43 is performed by taking in air in the washroom 42 and the like from the air intake 54a. Drying of can be promoted.

  In addition, when the cool wind mode button 55c of the operation panel 55 is pressed by the user and the cool wind operation mode is selected, the control unit 60 performs the same control operation as the dry operation mode described above except that the heater 18 is stopped. Execute. For this reason, even when the bathroom air conditioner 1 is operated in the cool air operation mode, the first ventilation rectification member 19a and the second ventilation rectification member are connected to the conduction path 10e in the same manner as the operation in the dry operation mode described above. 19b, and the conduction path 11e is provided with the first circulation rectification member 20a and the second circulation rectification member 20b, and these rectification members suppress the turbulence of the air flow in the conduction path 10e and the conduction path 11e. Thus, smooth air discharge can be realized, and generation of noise due to turbulence of the airflow can be suppressed.

  Further, since the foamed rubber 16 is provided on the entire periphery of the bottom opening peripheral edge portion 10b of the ventilation fan case 10, the ventilation fan motor 14d and the circulation fan motor 15d provided in the circulation fan case 11 are circulated by weights and the like. Even if the fan case 11 may be bent or the circulation fan case 11 may be slightly distorted due to changes over time, temperature deformation, or the like, the fan case 11 is provided at the contact portion between the ventilation fan case 10 and the circulation fan case 11. The foamed rubber 16 expands and contracts so as to block the gap between the ventilation fan case 10 and the circulation fan case 11, and the outflow of air from the contact portion can be prevented. For this reason, it is possible to prevent the air passing through the conduction path 10e from leaking to the outside of the blower unit 3 from the gap between the contact portions and generating noise such as whistling noise and wind noise.

  In addition, since the foamed rubber 16 also serves as a cushioning material, vibrations such as pulsation of airflow generated by the rotation of the ventilation sirocco fan 14a are transmitted from the ventilation fan case 10 to the circulation fan case 11 through the contact portion. It is possible to prevent the vibration accompanying the driving of the ventilation fan motor 14d and the circulation fan motor 15d from being transmitted from the ventilation fan case 10 to the circulation fan case 11. For this reason, it can prevent that the vibration produced by the ventilation fan unit 14 or the circulation fan unit 15 is transmitted to the whole ventilation unit 3 via an abutment part, and the noise reduction of the whole bathroom air conditioner 1 is carried out. Can be achieved.

  By operating the bathroom air-conditioning apparatus 1 in the cool air operation mode, it is possible to exhaust high-humidity air in the bathroom 43 and blow out cool air according to the temperature in the bathroom 43 while circulating the air in the bathroom 43. Therefore, the bathroom air conditioner 1 can be used as a fan in the summer.

  As described above, in the bathroom air conditioner 1 provided with the blower according to the present invention, the foamed rubber 16 is provided on the entire periphery of the bottom opening peripheral portion 10b of the ventilation fan case 10, so that, for example, circulation There is a possibility that the circulation fan case 11 is bent due to the weight of the ventilation fan motor 14d and the circulation fan motor 15d provided in the fan case 11, or that the circulation fan case 11 is slightly distorted due to a change with time, temperature deformation, or the like. However, the foamed rubber 16 provided at the contact portion between the ventilation fan case 10 and the circulation fan case 11 expands and contracts so as to close the gap between the ventilation fan case 10 and the circulation fan case 11, and the The outflow of air can be prevented. For this reason, it can be prevented that the air passing through the conduction path 10e leaks out of the blower unit 3 from the gap between the contact portions, and noise such as whistling noise and wind noise is generated.

  In particular, as in the bathroom air conditioner 1 shown in the present embodiment, when the ventilation fan case 10 is suspended so as to ensure a certain spatial distance L from the ceiling surface at the upper end of the main body case 2, If the circulation fan case 11 is bent due to the weight of the ventilation fan motor 14d or the circulation fan motor 15d, a gap is likely to be generated at the contact portion between the ventilation fan case 10 and the circulation fan case 11. For this reason, by attaching the foamed rubber 16 to the entire periphery of the bottom opening peripheral portion 10b of the ventilation fan case 10, the generation of gaps can be more effectively suppressed and the generation of noise such as wind noise can be prevented. Is possible.

  In addition, as described in the present embodiment, the ventilation fan case 10 and the circulation fan case 11 are fixed in a state where other members such as the floor plate portions 17a and 17b are bonded to the upper surface of the ceiling surface of the circulation fan case 11. The foamed rubber 16 can effectively close the gap that is likely to occur between the circulation fan case 11 and another member or between the ventilation fan case 10 and another member by the bent circulation fan case 11. It becomes.

  Further, even when it is necessary to pass the cable through the gap between the contact portions of the ventilation fan case 10 and the circulation fan case 11, the gap that may be generated by the cable due to expansion / contraction of the foam rubber 16 can be closed. Can be effectively suppressed.

  Further, since the foamed rubber 16 also serves as a cushioning material, it is possible to prevent the vibration of the ventilation fan unit 14 and the circulation fan unit 15 from being transmitted to the entire blower unit 3 through the contact portion. In addition, it is possible to reduce the noise of the entire bathroom air conditioner 1.

  As mentioned above, although embodiment of the bathroom air conditioner 1 was divided and classified for every operation mode, the air blower 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 conceived within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the present embodiment, the foam rubber 16 is provided on the entire periphery of the bottom opening peripheral edge portion 10b of the ventilation fan case 10, but the foam rubber 16 is not necessarily provided on the entire periphery of the bottom opening peripheral edge portion 10b. It should just be installed in the contact | abutting surface of the ventilation fan case 10 and the circulation fan case 11, and the space | gap is easy to produce. For example, as described in the present embodiment, when another member such as a floor plate portion is attached to the ceiling surface of the circulation fan case 11 or the like, a gap tends to be easily generated at the place where the other member is attached. Since it is strong, it is possible to effectively suppress the generation of gaps by installing the foamed rubber 16 in such a place.

  Furthermore, in the above-described embodiment, the explanation has been made using the unitized circulation fan unit 15 and the ventilation fan unit 14, but the rotary fan is not necessarily limited to the unitized one. A motor or the like may be configured separately. Furthermore, although the case where a sirocco fan was used as a fan for ventilation was described in the above embodiment, the rotary fan is not necessarily limited to a sirocco fan, and a multi-blade fan such as a radial fan is used. There may be.

  Moreover, although the ventilation fan unit 14 was shown and demonstrated in the said embodiment, the example of a structure arrange | positioned on the upper side of the circulation fan unit 15 was demonstrated, the circulation fan unit 15 is the ventilation fan unit 14 of this invention. It is good also as a structure arrange | positioned at an upper side.

  Furthermore, in the said embodiment, although the bathroom air conditioner 1 which performs ventilation and circulation of air by a separate sirocco fan using the circulation fan unit 15 and the ventilation fan unit 14 was demonstrated, the ventilation fan unit 14 and the circulation fan unit 15 may be shared by a single fan unit, and a damper or the like may be used to control air ventilation and circulation. Even in such a structure, the fan case base to which the fan motor and the sirocco fan are fixed and the fan case main body placed on the fan case base so as to contain the sirocco fan and the like are in contact with each other. By installing the foam rubber at the contact portion, the foam rubber expands and contracts so as to block the gap between the fan case base and the fan case main body, and noise such as whistling noise and wind noise can be prevented.

  Also in such a structure, the foamed rubber plays a role as a cushioning material, so the vibration of the fan unit (vibration such as pulsation of airflow generated by the rotation of the sirocco fan, vibration due to driving of the fan motor, etc.) Can be prevented from being transmitted to the entire blower unit through the abutting portion, and the entire bathroom air conditioner can be silenced.

  Furthermore, the foamed rubber described as the elastic member in the present embodiment is not limited to the one shown in the embodiment, and other rubber members (for example, rubber having no foaming property), silicon members, and the like. The elastic member may be used.

  Moreover, although the bathroom air conditioner 1 shown in the said embodiment was set as the structure which arrange | positions the rotating shaft 14e of the ventilation sirocco fan 14a and the rotating shaft 15e of the circulation sirocco fan 15a in the perpendicular direction, the rotating shaft of the ventilation sirocco fan 14a is set. 14e and the rotating shaft 15e of the circulation sirocco fan 15a may be arranged horizontally.

  Furthermore, although the bathroom air conditioner 1 shown in the said embodiment was set as the structure which arrange | positions the ventilation fan unit 14 and the circulation fan unit 15 up and down, the structure which arrange | positions the ventilation fan unit 14 and the circulation fan unit 15 on right and left It may be.

  Moreover, although the bathroom air conditioner 1 was demonstrated in embodiment mentioned above, the air blower which concerns on this invention is not limited to the air conditioner for bathrooms, Even if it is an air conditioner used other than a bathroom Good.
