Embodiment approach 1

[0027] use Figure 1 ~ Figure 4 The ventilator 30 according to Embodiment 1 will be described.

[0028] Such as figure 1 , figure 2 As shown, the ventilator 30 according to Embodiment 1 protrudes from the ceiling opening 3 of the ceiling 2 of the room 1 (for example, a high-humidity bathroom, etc.), and is installed in the ceiling 4 . The ventilation device 30 includes a frame 5 , a fan 9 and a decorative panel 20 . The appearance of the frame 5 is box-shaped, such as a substantially rectangular parallelepiped, with an opening 6 on its lower surface, and a frame outlet 8 for connecting to a pipe 7 communicating with the outdoors on one side. Furthermore, a fan 9 is provided inside the frame 5 . The blower 9 is composed of a centrifugal blower blade 10 , a scroll-shaped housing 11 that surrounds the outer peripheral portion of the centrifugal blower blade 10 , and a motor 12 . In addition, the centrifugal fan 10 is fixed to the rotating shaft 28 of the motor 12 .

Embodiment approach 2

[0049] use Figure 5 The ventilator 50 according to Embodiment 2 will be described. In addition, the same code|symbol is used for the same structure as Embodiment 1, and detailed description is abbreviate|omitted.

[0050] Such as Figure 5 As shown, in the ventilator 50 according to Embodiment 2, the first circulation port 18 and the second circulation port 19 are provided with shielding portions 27 for adjusting the opening area, that is, the opening ratio. For example, by sliding the shielding portion 27, the openings of the first circulation port 18 and the second circulation port 19 can be enlarged or reduced to adjust the aperture ratio. In addition, as a configuration for adjusting the aperture ratio, a method of opening and closing the shielding portion 27 or a method of attaching the shielding portion 27 are conceivable, but any configuration is acceptable as long as the aperture ratio can be adjusted. The shielding portion 27 may be included only in either one of ...

Abstract

A ventilation device (30) is provided with a box-shaped frame (5), a centrifugal blower (9), and a decorative panel (20). The decorative panel (20) is provided with a panel suction port (21) in the central section thereof and a panel discharge port (22) in the peripheral edge section thereof. The blower (9) is arranged within the frame (5) and comprises a casing (11) and centrifugal blower blades (10) that are arranged within the casing (11). The casing (11) has a scroll shape and comprises, in the lower surface thereof, a blower suction port (15) that communicates with the panel suction port (21). The side wall (13) of the casing (11) comprises: a first circulation port (18) in an area on the downstream side in the direction of rotation of the centrifugal blower blades (10) on the side opposite from a blower discharge port (14); and a second circulation port (19) in an area that does not overlap with the first circulation port (18) in a planar view. The first circulation port (18) and the second circulation port (19) each communicate with the panel discharge port (22).

Description

technical field [0001] The invention relates to a ventilating device which is embedded in an opening of a ceiling and is connected with a pipe arranged in the ceiling and communicated with the outdoors to ventilate the room. Background technique [0002] In the prior art, there is known a ventilating device that, in addition to exhausting indoor air to be ventilated to other spaces outside the room, also supplies air from other spaces outside the room to the room while exhausting the room air used as the object of ventilation. Ventilation and drying are performed more efficiently by exhausting the indoor air to be ventilated (for example, refer to Patent Document 1). [0003] Refer to the following Figure 6 Such a ventilator will be described. [0004] Such as Figure 6 As shown, the ventilation device 101 is installed in the roof interior space or the ceiling interior space of the building. The air supply type ventilator 102 for supplying air to the ventilator 101 is als...
