[0006]

However, as shown in FIGS. 4 and 5, the conventional louver 1 for blowing air is not provided with an air purifying function. For this reason, for example, when outside air is sent into the vehicle, dust and the like also enter the vehicle at the same time, and there is a concern that the interior of the vehicle becomes unsanitary.

The present invention has been made to solve the above problems. An object of the present invention is to provide a blower louver with an air purifying function to suppress intrusion of dust and the like into a room such as a vehicle from a blower opening.

[0008]

A blower louver according to the present invention is for sending air into a room such as a vehicle. Then, an air cleaning means is provided in the louver for blowing air. Here, the air purifying unit refers to a unit having a function of purifying air by removing foreign substances such as dust mixed in the air. Further, in the specification of the present application, not only a substantially closed space such as a vehicle interior but also a partially open space is defined as being included in the concept of the “indoor”.

By providing the air purifying means in the louver for ventilation as described above, even if air containing foreign matter such as dust is fed into the louver for ventilation, the foreign matter can be removed. Thus, clean air can be sent into the room such as the vehicle interior through the louver for air blowing, and it becomes possible to effectively prevent the room from becoming unsanitary.

It is preferable that an opening / closing member for opening / closing an air passage is provided in the louver.
Further, the air purifying means may be a filter arranged so as to close the air passage when the air passage is opened by the operation of the opening / closing member.

As described above, by disposing the filter so as to close the passage in response to the opening of the air passage by the opening / closing member, the air sent into the louver passes through the filter and passes through the air outlet. It will be sent indoors. This makes it possible to remove foreign matter such as dust mixed in the air sent into the louver by the filter. As a result, clean air is sent into the room through the louver. Further, by operating the filter in conjunction with the opening / closing member, it becomes possible to automatically perform air cleaning simply by operating the opening / closing member to open the air passage. Thereby, it is possible to easily perform air cleaning without a new operation for air cleaning.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment and a modification of the present invention will be described below with reference to FIGS.
FIG. 1 is a side view showing a blower louver 1 according to the present invention. FIG. 1A shows a state in which the air passage in the louver 1 is closed, and FIG. 1B shows a state in which the air passage is opened.

Referring to FIGS. 1 (a) and 1 (b), the blower louver 1 includes a casing 2, a flap 3, a filter 4, a dial 5, and connecting members 6a, 6b. The casing 2 is formed of a resin hollow member having both ends opened, and the opening on the side where the dial 5 is installed serves as a blower port.

The dial 5 is made of, for example, a resin, and is rotatably mounted on the outer surface of the casing 2. The connecting members 6a and 6b are also made of resin or the like, and connect the flap 3 and the filter 4 to the dial 5.
One ends of the connecting members 6a and 6b are rotatably connected to each other,
The other end of the connecting member 6a is rotatably connected to the dial 5.

Here, using FIG. 2A, FIG.
The structure of the flap 3 and the filter 4 in the state described above will be described in detail.

Referring to FIG. 2A, flap 3 is made of, for example, a plate-like resin, and a filter 4 is provided coaxially with flap 3. More specifically, the flap 3 and the filter 4 are provided coaxially so as to be substantially orthogonal to each other. Then, the shaft and the other end of the connecting member 6b are connected.

The filter 4 in the embodiment shown in FIG.
It is formed by attaching a net inside a resin frame member. Here, the flap 3 and the filter 4 can be integrally formed by using the same material for the frame member of the filter 4 and the flap 3. Specifically, the nets can be integrally formed by placing the nets in a mold in advance and performing insert molding. Note that a filter different from the type shown in FIG. 2 may be used as the filter 4.

Next, referring to FIGS. 1B and 2B, a state in which the air passage in the louver 1 is closed as shown in FIGS. 1A and 2A. The operation of opening the air passage from the opening will be described.

As shown in FIG. 1B, FIG.
The dial 5 is rotated according to the arrow 7 from the state shown in FIG. Thereby, the connecting members 6 a and 6 b are respectively operated to rotate, and the flap 3 and the filter 4 are operated to rotate according to the arrow 9. Thereby, as shown in FIG. 2B, the filter 4 is disposed so as to close the air passage in the louver 1. In this state, air is sent through the louver 1 into a room such as a vehicle according to the arrow 8 in FIG.

At this time, since the filter 4 is disposed so as to close the air passage in the louver 1 as described above, the air passes through the filter 4 and is sent into the room. Thus, foreign matter such as dust in the air can be removed by the filter 4, and clean air can be sent into the room.

Further, since the filter 4 can be automatically rotated by rotating the flap 3, a new operation for exhibiting the air cleaning function is not required. Therefore, the operation itself does not become complicated. Further, since the flap 3 and the filter 4 can be integrally formed as described above, the cost can be reduced. Further, it is considered that by adding a germicidal / antifungal function to the filter 4 itself, it becomes possible to more effectively exert the air cleaning function.

Next, a modification of the flap 3 will be described with reference to FIG. FIGS. 3A and 3B are diagrams schematically showing a structure of a modified example of the flap 3.

Referring to FIGS. 3A and 3B, in this modification, the flap 3 includes a plurality of plate members 3a to 3e. Each of the plate members 3a to 3e has an axis, and is rotatable around the axis. Filters 4a to 4d are provided at one ends of the plate members 3a to 3e.
Are respectively attached. These filters 4a to 4d
Preferably has flexibility.

In the state shown in FIG.
The inside air passage is closed by the plate members 3a to 3e. In order to open the air passage in the louver 1, the plate-like member 3a needs to be moved from the state shown in FIG.
To 3e are respectively rotated according to the arrows. Thereby, as shown in FIG. 3 (b), the plate members 3a to 3e
Are separated from each other, and the filters 4a to 4d are respectively arranged so as to close the air passage in the louver 1. As a result, foreign substances such as dust can be removed from the air passing through the air passage in the louver 1 as in the case shown in FIG. 1 or FIG. Thereby,
The same effect as that shown in FIG. 1 or FIG. 2 can be expected.

It should be noted that a flap 3 having a structure other than that shown in FIGS. 1 to 3 can be employed as long as it can open and close the air passage in the louver 1. In the above-described case, the filters 4, 4a to 4, which operate in conjunction with the flap 3,
Although 4d has been described, the filters 4, 4a to 4d
It may not necessarily be connected to the flap 3, and may be attached to a member other than the flap 3, such as the casing 2. Further, air purifying means other than the filters 4, 4a to 4d may be provided in the louver 1.
