(Embodiment 1)
FIG. 1 shows a ventilation device installed on a ceiling provided with a main body opening 1 serving as a suction port on the lower surface, an exhaust port 2 formed on a side, and a blower 5 including a centrifugal blower blade 3 and a motor 4 inside. 6 shows a state in which the ventilation device louver 6a is installed. The ventilator louver 6a includes a decorative panel 8 provided in the main body opening 1 and having a suction opening 7 communicating with the room. The decorative panel 8 is attached by an attachment spring 9 so as to cover the main body opening 1 of the ventilation device 6. And the 1st filter 10a and the 2nd filter 10b are arrange | positioned in the ventilation downstream of the decorative panel 8. FIG.

  As shown in FIG. 1, the decorative panel 8 is formed in a dish-like shape with an outer periphery raised, and is disposed under the main body opening 1 of the ventilator 6 so as to cover the main body opening 1. The space 8 a is provided between the opening 1 and the decorative panel 8. The first filter 10 a and the second filter 10 b are arranged inside the decorative panel 8.

  The decorative panel 8 has a first filter passage air passage 8b that ventilates the ventilation device 6 through the first filter 10a from the space 8a, and ventilation from the space 8a without passing through the first filter 10a. A non-first filter passage air passage 8c that ventilates the inside of the device 6 is provided.

  Furthermore, the area of the first filter 10 a is smaller than the opening area of the main body opening 1.

  As a result, a non-first filter passage air passage 8c through which air is ventilated from the space 8a into the ventilation device 6 without passing through the first filter 10a is formed. And it is set as the structure provided with the 2nd filter 10b in the non 1st filter passage air path 8c.

  As shown in FIG. 2, the first filter 10a is arranged in the center of the decorative panel 8, and the first filter 10a is located outside the first filter 10a and on the blower side, that is, downstream of the outer periphery of the first filter 10a. An annular second filter 10b surrounding the outer periphery is provided. That is, the second filter 10b is provided in the non-first filter passage air passage 8c.

  Here, the first filter 10 a is detachably attached to the decorative panel 8 by the mounting bracket 12 so as to provide a space 8 a between the suction opening 7 of the decorative panel 8. As shown in FIG. 3, a plurality of louver lattices 13 are provided in the suction opening 7 of the decorative panel 8. Each of the first filter 10 a and the second filter 10 b is formed from a plurality of filter lattices 14. Further, the plurality of louver gratings 13 in the suction opening 7 and the plurality of filter gratings 14 in the first filter 10a and the second filter 10b have a structure in which the direction and the interval coincide with each other.

  Furthermore, the first filter 10a and the second filter 10b are each integrally formed of a black resin. On the other hand, the decorative panel 8 is formed of a resin mixed with an antistatic agent.

  When the ventilator 6 installed on the ceiling surface with the above configuration is operated, indoor air is sucked into the decorative panel 8 through the suction opening 7 of the decorative panel 8 by the blower 5, and the decorative panel 8 is sucked from the suction opening 7. The air sucked into the air passes through the first filter passage air passage 8b through the first filter 10a from the space 8a provided between the suction opening 7 and the first filter 10a. After passing, the air is drawn into the ventilation device 6 through the main body opening 1 and then discharged to the outside from the side exhaust port 2.

  As described above, when the first filter 10a is not clogged, the air sucked from the suction opening 7 of the decorative panel 8 passes through the first filter 10a, so that large dust and dirt are removed. The blower 5 in the ventilator 6 is prevented from becoming dirty.

  On the other hand, when the first filter 10a is clogged for a long period of time, a space 8a is provided between the suction opening 7 of the decorative panel 8 and the first filter 10a, and the first filter 10a extends from the space 8a to the first filter 10a. In addition to the first filter passage air passage 8b that ventilates into the ventilator 6 through the filter 10a, the non-first filter passage air passage 8c that vents from the space 8a into the ventilator 6 without passing through the first filter 10a. Therefore, the main body opening 1 communicates with the space 8a provided between the suction opening 7 of the decorative panel 8 and the first filter 10a by the non-first filter passage air passage 8c. .

  That is, since the non-first filter passage air passage 8c that does not pass through the first filter 10a from the suction opening 7 into the ventilation device 6 is formed, when the first filter 10a is clogged, Since the air passage with little pressure loss, that is, the non-first filter passage air passage 8c can pass through, even if the pressure loss of the first filter 10a increases, the air enters the ventilation device 6 from the gap between the decorative panel 8 and the ceiling. The ceiling surface can be prevented from being soiled without inhaling.

  The first filter 10a is clogged by providing the first filter 10a on the downstream side of the air passage of the decorative panel 8 and providing a space between the suction opening 7 and the first filter 10a. However, it is difficult to see from the room and the appearance is not impaired.

  Further, since the area of the first filter 10a is smaller than the area of the main body opening 1, the non-flowing air from the space 8a in the decorative panel 8 into the ventilation device 6 without passing through the first filter 10a. A sufficient space for the first filter passage air passage 8c can be secured.

  In addition, since the second filter 10b is provided in the non-first filter passage air passage 8c, the second filter 10a provided in the non-first filter passage air passage 8c when the first filter 10a is clogged. The filter 10b can collect dust.

  Then, even if the first filter 10a is clogged and the pressure loss of the portion covered with the first filter 10a increases, the second filter 10b is disposed downstream of the outer periphery of the first filter 10a. Therefore, the air sucked from the suction opening 7 passes through the space 8a between the suction opening 7 and the first filter 10a, and is disposed at the outer periphery downstream of the first filter 10a. It is sucked into the filter 10b. Thus, since it can inhale in the ventilation apparatus 6 from the part covered with the 2nd filter 10b, the maintenance period of the 1st filter 10a can be lengthened.

  That is, even if the first filter 10a is clogged, an air passage with less pressure loss is formed on the outer peripheral side of the first filter 10a. Therefore, the first filter 10a is disposed closer to the blower than the first filter 10a. Since the air is sucked into the ventilation device 6 from the portion covered with the second filter 10b, dust can be collected by the second filter 10b, and the maintenance period of the first filter 10a can be extended.

  Therefore, even if the maintenance of the first filter 10a is not immediately performed, air passes through the space 8a provided between the first filter 10a and the suction opening 7, and then the outer periphery of the first filter 10a. Since air can be sucked in by the second filter 10b arranged annularly downstream, the maintenance period of the first filter 10a can be extended.

  Each of the first filter 10a and the second filter 10b is integrally molded with a black resin and attached to the inside of the decorative panel 8 formed in a dish shape. A plurality of the first filters 10a and the second filter 10b provided in the suction opening 7 of the decorative panel 8 Since the louver grid 13 and the plurality of filter grids 14 of the first filter 10a and the second filter 10b are made to coincide with each other in direction and interval, the pressure loss can be reduced as much as possible, so that the air volume is not impaired. Furthermore, with this configuration, it is possible to provide a low-cost design that makes it difficult for the first filter 10a and the second filter 10b to be visually recognized.

  Further, molding the decorative panel 8 with a resin containing an antistatic agent makes it difficult for dust to adhere to the decorative panel 8.

  Thus, according to the ventilator louver of Embodiment 1 of the present invention, a space is provided between the suction opening 7 and the first filter 10a, and the ventilator is provided from the space 8a via the first filter 10a. In addition to the first filter passage air passage 8b that ventilates the inside of the air filter 6, a non-first filter passage air passage 8c that ventilates the space 8a into the ventilation device 6 without passing through the first filter 10a is provided. Since the air flow path that does not pass through the first filter 10a, that is, the non-first filter passing air path 8c is formed between the suction opening 7 of the panel 8 and the main body opening 1, for example, the first filter 10a Even if it is clogged, air will not be sucked in through the gap between the ceiling and the decorative panel 8, so the ceiling will not be stained with dust and ventilation can be continued. As a result, the collection power is good. It is possible to provide a high design of the filter louver.

  In the first embodiment, the decorative panel 8 is formed of a resin containing an antistatic material. However, the decorative panel 8 may be changed to a structure in which a coating for preventing electrification is applied. The device louver can also provide a filter louver with good collection power and high design.

  The ventilator louver according to the present invention is widely useful for air conditioners mounted on a ceiling and equipped with a filter.
