However, conventional ventilators such as the above have problems with reduced stability and safety in use as the heat generated from the ventilator motor is not properly dissipated in a high-temperature, dry desert climate, resulting in reduced cooling performance.

The present invention has been proposed to solve the above-mentioned conventional problems, and the purpose of the present invention is to provide a ventilation fan that exhausts indoor air to the outside, and is suitable for a high-temperature and dry desert climate, so that stability and safety in use can be secured even when used for a long time.

In order to achieve the above object of the present invention, the ventilator according to the present invention comprises: a ventilator body having a ventilation room between an intake port through which indoor air is sucked in and an exhaust port through which outdoor air is exhausted; a ventilator motor which receives power to generate rotational force; and a ventilator fan which is rotatably provided in the ventilation room and receives the rotational force generated by the ventilation motor to rotate and provide air transfer pressure during the ventilation; wherein, on the outer surface of the motor housing constituting the ventilation motor, a plurality of cooling plates having a length radially oriented toward the outside and auxiliary cooling tubes formed in a 'corn' shape are respectively provided to cool the motor housing by heat exchange in the process of capturing indoor air flowing into the intake port from the outside of the cooling plates and guiding it to the surface of the motor housing.

The ventilator according to the present invention, which is constructed in this manner, efficiently cools the ventilator motor through heat exchange between cooling plates and auxiliary cooling tubes respectively provided on the outer surface of the motor housing located indoors of a facility and exhaust air exhausted from the indoors to the outside.

Hereinafter, with reference to the attached drawings, a ventilator according to a preferred embodiment of the present invention will be described in detail as follows.

The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer explanation. It should be noted that in each drawing, the same parts are sometimes drawn with the same reference numerals. Detailed descriptions of well-known functions and configurations that are judged to unnecessarily obscure the gist of the present invention are omitted.

FIGS. 1 to 7 are drawings showing a ventilator (1) according to an embodiment of the present invention. The ventilator (1) according to the present embodiment is applied to a ventilator (3) in which a ventilator motor (3) is placed inside a facility to ventilate the interior of the facility, and efficiently cools the ventilator motor through heat exchange of exhaust air exhausted from the interior to the exterior. Accordingly, even when used for a long time in a high-temperature and dry desert climate, the ventilator motor (3) is prevented from being damaged by heat, thereby ensuring stability and safety in use.

A ventilator (1) according to this embodiment comprises a ventilator body (2) having a ventilator room (A) between an intake port (21) through which indoor air is sucked in and an exhaust port (22) through which air is exhausted to the outdoors; a ventilator motor (3) that receives power and generates rotational force; and a ventilator fan (4) that is rotatably provided in the ventilator room (A) and rotates by receiving the rotational force generated by the ventilator motor (3) to provide air transfer pressure during the ventilation.

That is, the ventilation fan (4) provided in the ventilation room (A) of the ventilation body (2) receives the rotational force generated by the ventilation motor (3) and rotates to form a suction pressure for indoor air inside the ventilation room (A) and a discharge pressure to the outside.

Accordingly, the indoor air is exhausted to the outside, thereby performing the indoor ventilation function.

The ventilation body (2) described above is formed in a 'pipe' shape with the center being penetrated to form the intake port (21), the exhaust port (22) and the ventilation room (A), and may be formed with a joining flange (23) formed to extend outward from the outer end on the side of the intake port (21) and be joined and fixed to the facility.

That is, the intake port (21), the exhaust port (22), and the ventilation room (A) can be formed by being fixed to a facility (ceiling, wall, etc.) through the above-mentioned connecting flange (23) to spatially connect the interior and exterior.

The ventilation fan (4) described above is configured to form an air transfer pressure from the intake port (21) toward the exhaust port (22) when rotating; its configuration and structure may be suitably applied by a configuration and structure selected by a user from among conventionally known technologies.

In the above, the ventilation motor (3) is controlled and driven by a control means (71) configured to control the power of the power supply unit (72), thereby generating rotational force to rotate the ventilation fan (4); as for its configuration and structure, a configuration and structure selected by a user from among conventionally known technologies can be suitably applied.

Meanwhile, the ventilation body (2) above may be provided with connecting supports (24) that are connected to the motor housing (31) of the ventilation motor (3) on the intake port (21) side to support the ventilation motor (3).

That is, the ventilation motor (3) can be placed on the intake port (21) side through the connecting supports (24).

Accordingly, indoor air that enters the intake port (21) and is then discharged through the exhaust port (22) can cool the ventilation motor (3).

Accordingly, by cooling the heat generated during operation, it is possible to prevent damage such as short-circuiting of fuses, connection cables, etc. during long-term use, thereby implementing stability and safety in use.

In the ventilator (1) according to this embodiment, on the outer surface of the motor housing (31) constituting the ventilator motor (3), a plurality of cooling plates (5) having a length radially oriented toward the outside and an auxiliary cooling tube (6) formed in a 'corn' shape are respectively provided to cool the motor housing (31) by heat exchange in the process of capturing indoor air flowing into the intake port (21) from the outside of the cooling plates (5) and guiding it to the surface of the motor housing (31).

That is, indoor air exhausted from the inside to the outside through the cooling plates (5) and the auxiliary cooling tube (6) provided on each outer surface of the motor housing (31) is captured through the auxiliary cooling tube (6), thereby maximizing contact with the cooling plates (5) formed on the surface of the motor housing (31), thereby increasing heat exchange efficiency and thus increasing cooling performance.

Accordingly, the ventilation motor (3) is efficiently cooled, and in particular, the ventilation motor (3) is prevented from being damaged by heat even when used for a long time in a hot and dry desert climate.

In the above, the cooling plates (5) can be provided in multiple radial arrangements on the outer surface and rear end surface of the motor housing (31).

That is, the cooling plates (5) are provided on each surface of the motor housing (31) except for the area facing the ventilation fan (4), so that the cooling area can be efficiently increased.

The cooling plates (5) arranged on the outer surface of the motor housing (31) above are arranged to have a length in the direction in which air sucked into the intake port (21) of the ventilation body (2) moves, so that the contact area with indoor air flowing into the intake port (21) can be efficiently increased.

In the ventilator (1) according to the present embodiment, which is formed in this manner, the auxiliary cooling tube (6) is formed as an 'inclined tube' with an inner diameter through which the motor housing (31) is arranged with a gap at both ends; however, the inner diameter gradually decreases as it goes toward the ventilator body (2).

That is, as the auxiliary cooling tube (6) is formed as an 'inclined tube' whose inner diameter gradually decreases as it moves in the direction in which indoor air is sucked into the intake port (21), heat exchange occurs as indoor air is captured inside the auxiliary cooling tube (6) and concentrated in a vortex shape.

Accordingly, the cooling efficiency of the auxiliary cooling tube (6) is improved.

Therefore, the cooling quality of the ventilation motor (3) is improved through efficient cooling of the auxiliary cooling tube (6) connected to the motor housing (31).

In the above, a connecting opening (61) may be formed in the auxiliary cooling tube (6) so that a portion (such as a power connection portion) protruding outward from the outer surface of the motor housing (31) passes through it.

That is, the auxiliary cooling tube (6) can be stably placed without damaging the portion protruding outwardly of the motor housing (31) through the connecting opening (61).

In the ventilator (1) according to the present embodiment formed as described above, one end of the auxiliary cooling tube (6) is provided with fastening pieces (62) whose ends are fastened to the outer surface of the motor housing (31).

That is, the auxiliary cooling tube (6) is fixedly supported to the motor housing (31) through the above-mentioned connecting pieces (62).

The above-mentioned fastening members (62) can be extended from the end with a small inner diameter in the auxiliary cooling tube (6) and fastened to the motor housing (31); the fastening configuration and fastening structure of the motor housing (31) and the fastening member (61) can be suitably applied by a fastening configuration and fastening structure selected by a user from among conventionally known technologies.

In the ventilator (1) according to the present embodiment, which is formed in this manner, the end portion of the auxiliary cooling tube (6) with a small inner diameter can be formed to be tailored to come into contact with a plurality of cooling plates (5) formed on the outer surface of the motor housing (31).

That is, the end of the auxiliary cooling tube (6) is brought into contact with the cooling pieces (5), thereby increasing the heat exchange efficiency for the cooling pieces (5), thereby improving the cooling performance.

In addition, in the process of indoor air being induced and passing through the gaps between the cooling plates (5) in the inner side of the auxiliary cooling tube (6) to the intake port (21), the air can move while cooling the inner side of the auxiliary cooling tube (6).

At this time, the inner surface of the auxiliary cooling tube (6) is formed as an inclined surface, so that air flow in a vortex shape can occur.

Accordingly, the cooling performance of the auxiliary cooling tube (6) can be maximized.

As described above, the ventilation fan (1) according to the present embodiment is characterized by a technical configuration in that it is suitable for application to a high-temperature, dry desert climate, as the contact between the exhaust air and the indoor air through the cooling plates (5) and the auxiliary cooling tube (6) respectively provided in the motor housing (31) is maximized, thereby efficiently cooling the ventilation motor (3).

The above-described embodiment of the present invention is merely exemplary, and those skilled in the art will readily appreciate that various modifications and equivalent other embodiments are possible. Therefore, it will be readily understood that the present invention is not limited to the forms mentioned in the above detailed description. Accordingly, the true technical protection scope of the present invention should be determined by the technical idea of the appended claims.
