Description

[Detailed description of the invention] [Industrial application field] The invention relates to a filter mounting structure of a ventilation blower which is mounted on, for example, a ceiling surface or a wall surface and exhausts sucked air to the outside through a pipe.

[Related Art] Ventilation blowers configured to exhaust air to the outside of a room through a pipe are often configured as disclosed in, for example, Japanese Utility Model Publication No. 52-11899 and Japanese Utility Model Publication No. 52-85755. . These are mounted by inserting and fixing the main body of the ventilation blower to a pipe passed through a wall hole formed in the wall. However, in this type, there is a problem that the diameter of the wall hole becomes large, and a ventilation blower (a product is a ventilation fan) having a configuration as shown in FIG. ing. That is, the main body 1 which can be attached to a wall surface or a ceiling surface is covered with a detachable box-shaped grill 2, and the suction port 4 of the blower 3 of the main body 1 is connected to a pipe passing through the wall. I have.

In this ventilated blower, since the main body 1 is not inserted into the pipe, the pipe may have a small diameter and a small hole in the wall.

[Problem to be Solved by the Invention] In a conventional ventilated blower, a filter 6 in which a net material as shown in FIG. 8 is formed in a container shape is attached to a suction port 5 of a main body 1 in a cap state. There is a problem to be solved such that the filter 6 falls off relatively easily due to the operation of engaging and disengaging the grill 2 or vibration.

The present invention has been made to solve such a conventional problem, and its purpose is to provide a suction port 5 of a filter 6 made of a net material.
It is an object of the present invention to obtain a filter mounting structure for a ventilation blower, which can be stably mounted on a filter.

[Means for Solving the Problems] The filter mounting structure of the ventilated blower according to the present invention is a ventilated blower in which a filter in which a net material is formed into a container shape is detachably fitted to and attached to a suction port of the blower. The entire end surface of the fitting side and the entire inner and outer periphery of the end portion are integrally covered with a foamable cushioning material, and the suction port of the blower is formed in a cylindrical shape so that the fitting side of the filter can be fitted to the outside. Are fixed by elastic deformation of the cushion material.

In addition, another filter mounting structure of the ventilated blower of the present invention is a ventilation blower in which a filter formed of a net material formed into a container shape is detachably fitted to a suction port of the blower, and the suction port of the blower is fitted into the filter. The side has a cylindrical shape that can be fitted externally, and has several ribs that extend in the center line direction on the outer periphery thereof and that receive the fitting by expanding the filter.

[Function] In the filter mounting structure of the ventilated blower of the present invention, the filter is held at the suction port by the elastic force of the cushion material, and the end face of the filter which is easily deformed or damaged is protected by the cushion material. become.

In the filter mounting structure of another ventilated blower of the present invention, the strength of the suction port is increased by the rib, and the filter is mounted in a tensioned state by the rib.

FIG. 1 is a plan view of a ventilated blower according to the present invention, and FIG.
The figure shows the front view, and FIG. 3 shows the filter mounting structure.
4 to 7 show other embodiments of the filter mounting structure. First, the embodiment shown in FIGS. 1 to 3 will be described. This ventilation blower has the same basic configuration as the conventional ventilation blower shown previously in FIG. The structural feature lies in the filter mounting structure. That is, the suction port 5 of the main body 1 is formed in a cylindrical shape, and a filter 6 in which a net material such as a wire net or a resin net is formed in a container shape.
Are detachably fitted. This filter 6
A foamed cushioning material 7 having heat insulating properties is coated and integrated on the end face on the fitting side and the inner and outer peripheries of the end portion.

The filter 6 is attached to the suction port 5 by the cushion material 7 being shrunk and interposed between the outer periphery of the suction port 5 and the end of the filter 6. 5 is maintained in a stable state. In addition, the end face of the filter 6 that is easily deformed or damaged is protected by the cushion material 7.

The filter mounting structure of the other ventilation blower shown in FIGS. 4 to 7 is characterized in particular by the configuration on the suction port 5 side.
That is, the suction port 5 of the main body 1 is formed in a cylindrical shape capable of fitting the filter 6 to the outside, and several ribs 8 extending in the center line direction are formed on the outer periphery thereof. The open end face of the rib 8 is formed in an arc shape so that the filter 6 can be easily fitted.

In this embodiment, the filter 6 is attached to the suction port 5 by deforming the fitting side of the filter 6 by the rib 8. That is, the fitting side of the filter 6 is expanded by the rib 8, and the filter 6 comes into close contact with the outer periphery of the suction port 5 in a tensioned state as shown in FIG. There is also an advantage that the strength of the suction port 5 is increased by the ribs 8.

[Effects of the Invention] As described above, according to the filter mounting structure of the ventilated blower of the invention, the filter is stably held in the suction port by the elastic force of the cushioning material, is not easily dropped off, and is easily deformed or damaged. Can be protected by a cushion material, and can be provided with a fixing function by itself with a simple structure integrated with the filter.

In addition, according to the filter mounting structure of the ventilation fan according to the present invention, the suction port can be reinforced by the ribs, and the filter can be stably mounted in the tension state where the filter is expanded without providing a special structure. Can be.
