[0004] [Patent Document 1] JP 2010-112622 A Summary of the Invention [Problem to be solved by the invention]

[0005] The location where the storage unit for storing electrical components is to be attached is preferably flat, taking into consideration the ease of installation and the stability of the installed state. Therefore, the storage unit is attached to the surface 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.

[0006] In recent years, as the shape of the air tunnel section has become more complex and the ventilation fan itself has become smaller, it has become difficult to secure a flat surface on which the storage section can be attached on the side of the main frame facing the cylindrical section.

[0007] The present disclosure has been made in consideration of the above, and has an object to provide a ventilation fan in which it is easy to ensure space for providing a storage section for storing electrical components. [Means for solving the problem]

[0008] In order to solve the above problems and achieve the object, the ventilator according to the present disclosure comprises: It has an inner surface and an outer surface which is the opposite surface facing the inner surface. A cylindrical air tunnel, a main body frame provided at one end of the air tunnel in a flange-like shape, a support leg fixed to the main body frame or the air tunnel, an electric motor supported by the support leg, and a rotor connected to the electric motor for rotation. , which faces directly the inner surface of the wind tunnel The fan comprises a blade, a storage section integrally molded on the outer surface of the air tunnel section, and an electric component stored inside the storage section. Effect of the Invention

[0009] According to the present disclosure, it is possible to obtain an exhaust fan in which it is easy to ensure space for providing a storage section for storing electrical components. [Brief description of the drawings]

[0010] [Figure 1] FIG. 1 is a front view of a ventilation fan according to a first embodiment; [Diagram 2] FIG. 1 is a side view of a ventilation fan according to a first embodiment; [Diagram 3] FIG. 1 is a side view of the ventilation fan according to the first embodiment with the cover removed; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, a ventilation fan according to an embodiment will be described in detail with reference to the drawings. However, the present disclosure is not limited to the embodiment.

[0012] Embodiment 1 Fig. 1 is a front view of the exhaust fan according to the first embodiment. Fig. 2 is a side view of the exhaust fan according to the first embodiment. Fig. 3 is a side view of the exhaust fan according to the first embodiment with a cover removed. The exhaust fan 10 includes a main body frame 1, an air duct 2, support legs 3, an electric motor 4, blades 5, and a storage section 6.

[0013] 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.

[0014] 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 2. The blades 5 are connected to the output shaft of the electric motor 4 and are rotatable.

[0015] In the ventilation fan 10, the blades 5 are rotated by the electric motor 4, thereby generating an airflow from one side of the air tunnel 2 to the other side.

[0016] The storage section 6 has a box-shaped main body 6b with an opening 6a formed on one side thereof for storing electrical components such as a capacitor and a circuit inside, and a lid 6c for closing 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 closing the opening 6a with the lid 6c, the electrical components inside can be protected from dust and moisture.

[0017] 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, when the storage section 6 is provided and attached separately from the wind tunnel section 2 without being integrally molded with the wind tunnel section 2, it is necessary to attach it 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.

[0018] If it becomes easier to secure the space for providing the storage section 6, it will be possible to provide a larger storage section 6. This will allow more electrical components to be mounted on the ventilator fan 10. By providing more electrical components, it will be possible to improve the performance of the ventilator fan 10.

[0019] Conversely, if it is easy to secure the space for providing storage section 6, it is possible to make ventilator 10 smaller than a ventilator fan having a separate storage section of the same size.

[0020] Furthermore, since the storage section 6 is molded integrally with the air tunnel section 2, the task of fixing the storage section 6 is not required, and the number of steps in assembling the ventilator fan 10 can be reduced.

[0021] The storage section 6 may have any shape as long as it can store electrical components therein. In addition, if dust and moisture are not a problem due to the environment in which the ventilator fan 10 is installed, the storage section 6 may not be provided with a lid 6c, thereby reducing the number of components.

[0022] 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, so long as it can be molded integrally.

[0023] Moreover, the storage section 6 may be provided on the back surface 1b of the main body frame 1, and the main body 6b may be integrally molded with the main body frame 1. In this case as well, the storage section 6 can be provided in a non-flat area of ​​the back surface 1b, making it easier to secure space for the storage section 6.

[0024] Also, a plurality of storage sections 6 may be provided. By providing a plurality of 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. Also, when a plurality of storage sections 6 are provided, some of the storage sections 6 may be integrally molded with the main body frame 1, and some of the storage sections 6 may be integrally molded with the air tunnel section 2.

[0025] Furthermore, if multiple storage sections 6 are provided, it becomes possible to mount more electric components in the ventilation fan 10. By providing more electric components, it becomes possible to improve the performance of the ventilation fan.

[0026] 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. Also, parts of the configurations may be omitted or modified without departing from the spirit of the invention. [Explanation of symbols]
