Abstract

PURPOSE:To provide a function to perform not only exhaust of air at the interior of a room but also exhaust of air in the ceiling of a house and to improve facility by a method wherein a slide panel slid along with vertical movement of a panel within a outer casing is protruded in a panel and a communicating hole with a suction port in a ceiling during superposition of a panel with an opening is formed in the slide panel. CONSTITUTION:An outer casing 11 of a ventilating fan incorporates a blower 10a, has an opening 13 on the indoor side 12, and is formed by a box body. When a panel 20 is superposed with the opening 13 and the blower 10a is run in a state that a suction port 14 in a ceiling is communicated with a communicating port 23 outdoor air is sucked in a space 9 in a ceiling through a suction gallery 24, ad air in the space 9 in the ceiling is discharged to the outdoor side. This constitution enables dehumidification of the space 9 in the ceiling and reduces a room temperature during a summer season. Only indoor air is discharged in a way that the panel 20 is lowered down, the suction port 14 in the ceiling is sealed with a slide panel 22, and the communicating port 23 is positioned on the indoor side 12. Further, through vertical movement of the panel 20, the open air through an exhaust duct 18 during a winter season is shut off and cold air is prevented from entrance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ventilation fan that performs an exhaust function in a room and attic.

[Conventional technology]

Conventionally, this type of ventilation fan has been installed on the ceiling (as shown in Figure 12).
An opening (2) is provided in 11 etc., an outer casing (4) with a blower (3) installed inside is attached to this opening, and an exhaust duct (6) is connected to the discharge port (51) provided on the side wall of this outer casing. After that, a suction grill (7) is attached to the opening f21 from the indoor side, and the air inside the room is exhausted to the outside through the exhaust duct (6) by operating the air blower R (3). (
For example, see Utility Model Application Publication No. 57-108020).

[Problem to be solved by the invention]

Conventional ventilation fans such as those mentioned above only have the function of exhausting indoor air, but cannot exhaust the hot air, moisture, etc. from behind the ceiling (1), and are insufficient to protect and manage the house. There was a problem.

This invention was made to solve the problem,
To provide an easy-to-use ventilation fan that can exhaust not only indoors but also the ceiling of a house, has a sufficient ventilation function for a house, and is convenient to use.

[Means to solve the problem]

The ventilation fan according to the present invention is arranged in the ceiling of a house, etc. with an internal blower, and has an outer casing made of a box having an opening on the indoor side, and an in-ceiling suction provided on the side wall of the outer casing. The panel includes an opening and a discharge port, and a panel that covers the opening from the indoor side, and a slide plate that slides in the outer casing by vertical movement of the panel is provided on the panel, and the panel covers the opening on the slide plate. A communication hole is provided which communicates with the inlet in the ceiling during polymerization.

In addition, an outer casing consisting of a box with a blower installed inside and arranged in the ceiling of a house, etc. and having an opening on the indoor side, and an inlet and an outlet in the ceiling provided on the side wall of this outer casing. , a grill that covers the opening from the indoor side, an indoor suction port is provided in the grille, and a damper is provided in the outer casing to arbitrarily open and close either the indoor suction port or the ceiling suction port. This is what I did.

[Effect]

In this invention, an outer casing made of a box body with a feeder ff1fi installed inside the ceiling of a house, etc. and having an opening on the indoor side, and an inlet in the ceiling provided on a side wall of the outer casing. and a discharge port, and a panel that covers the opening from the indoor side,
A slide plate is protruded from the panel and slides when the panel moves up and down within the outer casing, and a communication hole is provided in the slide plate to communicate with the inlet in the ceiling when the panel overlaps with the opening. When the panel is lowered, the inlet in the ceiling is sealed with a slide plate, indoor air is sucked in through the communication hole in the panel, and exhausted through the outlet, and when the panel is raised, the panel and the opening overlap and the ceiling is closed. The internal suction port opens, and air from the ceiling is sucked in through the ceiling suction port and exhausted to the discharge port.

In addition, an outer casing consisting of a box with a blower installed inside and arranged in the ceiling of a house, etc. and having an opening on the indoor side, and an inlet and an outlet in the ceiling provided on the side wall of this outer casing. , a grill that covers the opening from the indoor side, an indoor suction port is provided in the grille, and a damper is provided in the outer casing to arbitrarily open and close either the indoor suction port or the ceiling suction port. Therefore, by opening and closing the damper, either the attic exhaust or indoor air can be vented as desired.
