Description

This disclosure relates to a ventilation fan that is installed in an opening formed in a wall surface, etc.

Ventilating fans that are installed in openings formed in the walls of buildings are known. This type of ventilating fan is equipped with a cylindrical air tunnel that is inserted into the opening, a main frame that is provided at one end of the air tunnel in a flange-like shape to close the gap between the opening and the air tunnel, support legs fixed to the main frame, an electric motor supported by the support legs, and blades rotatably connected to the electric motor. The fan exhausts air from one side of the opening to the other side by rotating the blades with the electric motor, thereby providing ventilation.

Some ventilation fans include electrical components such as a capacitor and circuitry. The electrical components are housed in a box-like storage compartment to protect them from dust and moisture.

JP 2010-112622 A

The location where the storage unit for storing electrical components is attached is preferably flat, taking into consideration the ease of installation and the stability of the installed state. Therefore, it was attached to one side of the main body frame facing the cylindrical portion. When the ventilation fan is attached to the opening, the storage unit is located in the gap between the cylindrical portion and the opening.

In recent years, as the shape of the air tunnel has become more complex and the ventilator itself has become smaller, it has become difficult to provide a flat surface on the side of the main frame facing the cylindrical section on which the storage section can be attached.

This disclosure was made in consideration of the above, and aims to provide a ventilator fan that makes it easy to secure space for a storage section to store electrical components.

In order to solve the above-mentioned problems and achieve the objectives, the ventilation fan disclosed herein comprises a cylindrical air tunnel section having an inner surface and an outer surface which is the opposite surface facing the inner surface , a main body frame provided in a brim-like shape at one end of the air tunnel section, support legs fixed to the main body frame or the air tunnel section, an electric motor supported by the support legs, blades rotatably connected to the motor and directly facing the inner surface of the air tunnel section, a storage section integrally molded with the outer surface of the air tunnel section, and electrical components stored inside the storage section.

The present disclosure has the effect of providing a ventilator that makes it easy to secure space for a storage section for storing electrical components.

FIG. 1 is a front view of a ventilation fan according to a first embodiment; FIG. 1 is a side view of a ventilation fan according to a first embodiment; FIG. 1 is a side view of the ventilation fan according to the first embodiment with the cover removed;

The following describes in detail the ventilation fan according to the embodiment with reference to the drawings. Note that the disclosure is not limited to the embodiment.

Embodiment 1.
Fig. 1 is a front view of a ventilation fan according to embodiment 1. Fig. 2 is a side view of the ventilation fan according to embodiment 1. Fig. 3 is a side view of the ventilation fan according to embodiment 1 with a cover removed. The ventilation fan 10 includes a main body frame 1, an air duct 2, support legs 3, a motor 4, blades 5, and a storage section 6.

The main body frame 1 is provided in a flange-like shape at one end of the air tunnel 2. The surface of the main body frame 1 facing the air tunnel 2 is called the back surface 1b, and the opposite surface is called the front surface 1a. The main body frame 1 has flat areas on both the front surface 1a and the back surface 1b.

The support legs 3 are fixed to the main body frame 1. The electric motor 4 is fixed to the support legs 3 at a position inside the air tunnel section 2. The blades 5 are connected to the output shaft of the electric motor 4 and are rotatable.

In the ventilation fan 10, the blades 5 are rotated by the electric motor 4, generating an airflow from one side of the air tunnel 2 to the other side.

The storage section 6 has a box-shaped main body 6b with an opening 6a formed on one side for storing electrical components such as a capacitor and a circuit inside, and a lid 6c for covering the opening 6a. The storage section 6 is provided on the outer surface of the air tunnel section 2. Of the storage section 6, the main body 6b is integrally molded with the air tunnel section 2. By covering the opening 6a with the lid 6c, the electrical components inside can be protected from dust and moisture.

According to the configuration described above, the storage section 6 can be provided on a curved surface such as the outer surface of the wind tunnel section 2. On the other hand, if the storage section 6 is not molded integrally with the wind tunnel section 2 but is provided separately and attached, it needs to be attached to a flat area such as the back surface 1b of the main body frame 1 in consideration of ease of attachment. Therefore, by integrally molding the storage section 6 with the outer surface of the wind tunnel section 2, the freedom of selection of the location to provide the storage section 6 is improved compared to when the storage section 6 is provided separately. This makes it easier to secure space to provide the storage section 6.

If it becomes easier to secure space for the storage section 6, it will be possible to provide a larger storage section 6. This will allow more electrical components to be installed in the ventilator 10. By providing more electrical components, it will be possible to improve the performance of the ventilator 10.

Conversely, if it is easy to secure space for the storage section 6, it is possible to make the ventilator fan 10 smaller than a ventilator fan with a separate storage section of the same size.

In addition, since the storage section 6 is integrally molded with the air tunnel section 2, there is no need to fix the storage section 6, which reduces the number of steps required to assemble the ventilator fan 10.

The storage section 6 may have any shape that allows electrical components to be stored therein. If dust and moisture are not a problem due to the environment in which the ventilation fan 10 is installed, the storage section 6 may be omitted to reduce the number of components.

The material of the storage section 6 may be the same as that of the main body frame 1 and the air tunnel section 2, as long as it can be molded as a single unit.

The storage section 6 may also be provided on the back surface 1b of the main body frame 1, and the main body 6b may be molded integrally with the main body frame 1. In this case, the storage section 6 can also be provided in a non-flat area of the back surface 1b, making it easier to secure space for the storage section 6.

In addition, multiple storage sections 6 may be provided. By providing multiple storage sections 6, each storage section 6 can be made smaller. Therefore, it becomes easier to secure space for providing the storage sections 6. Also, it becomes possible to separate the types of electrical components stored in each storage section 6, such as a storage section 6 that stores a capacitor and a storage section 6 that stores a circuit. In addition, when multiple storage sections 6 are provided, some of the storage sections 6 may be molded integrally with the main body frame 1, and some of the storage sections 6 may be molded integrally with the air tunnel section 2.

Furthermore, by providing multiple storage compartments 6, it becomes possible to mount more electrical components on the ventilator 10. By providing more electrical components, it becomes possible to improve the performance of the ventilator.

The configurations shown in the above embodiments are merely examples, and may be combined with other known technologies, or the embodiments may be combined with each other. In addition, parts of the configurations may be omitted or modified without departing from the spirit of the invention.
