Description

[Detailed Description of the Invention] This invention relates to a ventilation fan whose main body is equipped with functionally independent dual blowers, and which enables double ventilation at the same time.

Most of the ventilation fans of this type mentioned above are housed inside the space behind the ceiling or within the wall structure, and the outer shell of the main body, which usually has dual blowers built in, is completely open on one side toward the indoor side. There is.

It is not necessary to close the opening corresponding to one blower, but it is necessary to close the portion corresponding to the other blower used for ventilation of another room.

Therefore, conventionally, a part of the opening is closed with a blind lid, and a grille with intake holes is attached to the entire opening.

However, the entire opening and grille are exposed on the room side, giving a sense of discomfort, and it is time-consuming and expensive to install the blind lid and grille twice.

This invention has a simple configuration of the opening in the outer shell of the main body.

It is an object of the present invention to provide a ventilation fan that has a less Japanese feel and can reduce costs, thereby solving the above-mentioned conventional problems.

Next, the configuration of the present invention will be specifically explained based on an embodiment shown in the drawings.

The ventilation fan shown in Fig. 1 as an application example of the present invention has dual blowers 2 and 3 built into a main body outer shell 1 formed in the shape of a rectangular box with an opening on one side facing the indoor side. The room where the main unit is installed and some other rooms are ventilated at the same time.

Two exhaust ports 4 are formed side by side on one side of the main body outer shell 1 in correspondence with the blowers 2 and 3, and an intake port 5 is formed on the side facing the blower 3 used for ventilation of other rooms. It is being

A mounting flange 7 protrudes outward from the edge of the opening of the main body shell 1, which can be brought into contact with the indoor side surface of the mounting frame 6 in the ceiling.

The inside of the main body outer shell 1 is divided into two parts by a central mounting plate 8, and for each part, blowers 2 and 3, which mainly consist of a motor 9, blades 10, and fan casings 11 and 12, are arranged side by side. .

The motor 9 of each blower 2, 3 is common, and is fixed to the mounting plate 8 with its rotating shaft horizontally, and the blades 10 of each blower 2, 3 are fixed to the mounting plate 8 with the rotating shaft extending horizontally. They are each installed.

The free end side of the mounting plate 8 is located slightly below a level that coincides with the lower end of the circumferential side that defines the opening of the main body outer shell 1, and substantially doubles the opening of the main body outer shell 1.

The blower 2 ventilates the room in which the main body is installed, and the corresponding opening S1 in the outer shell 1 of the main body serves as an air intake port.

In addition, as mentioned above, the other blower 3 is used for ventilation of other rooms, and the corresponding opening S2 of the main body outer shell 1 has no use for ventilation, and is used as a blind cover section to be described later. 13.

The blind lid part 13 is formed as a part of a panel 14 attached to the entire opening of the main body outer shell 1.

The panel 14 has an air intake hole 1 in a portion corresponding to the opening portion S1.
5 in the form of a grill part 16, and a blind lid part 13 in the part corresponding to the opening part S2, and there is a mounting plate 8 on the back at the boundary between the grill part 16 and the blind lid part 13. A partition wall 17 is protruding from the wall.

The panel 14 is attached to the body shell 1 in the same manner as a normal grill, ie, by latching or screwing.

Note that the partition wall 17 of the panel 14 is connected to the mounting plate 8 of the main body outer shell 1.
A channel 18 is formed at either the end of the mounting plate 8 or the end of the partition wall 17, as shown in FIG. ,
If the other end is fitted into this channel 18, the isolation will be more reliable.

As is clear from the above explanation based on the embodiments, the ventilation fan of the present invention performs double ventilation at the same time using two types of built-in blowers. Since it is equipped with a panel that has the functions of both a grill for use and a blind cover for closure, a grill larger than necessary is not exposed against the ceiling or wall, so it does not feel out of place. Moreover, since the blind cover, which was conventionally required, is installed as a single member integrated with the grille and does not need to be installed separately, it is possible to reduce the number of mounting parts and parts, and thus to reduce costs.

Claims (1)

[Scope of utility model registration request] One side of the outer shell of the main body, which is recessed in the wall and has one side open facing the room, and the inside is divided into two sections, each of which has a ventilation blower, is placed in the opening facing the room. A grill section with an intake hole is formed in the part corresponding to one blower, and a panel with a blind lid part is attached to the part corresponding to the other blower so that the blower can be used to ventilate another room. Ventilation fan with this configuration.
