Accordingly, a connection guide 93 is formed at the cooling fan 130 (refer to FIG. 3) of the fan motor assembly 100 to form a connection flow path 94 through which air on the cooling flow path moves to the upper flow path 76. Is provided.

Hereinafter, the fan motor assembly 100 will be described in detail.

3 is a perspective view of a fan motor assembly according to the present invention, and FIG. 4 is a cross-sectional view taken along line II ′ of FIG. 3.

Referring to FIGS. 3 and 4, the fan motor assembly 100 according to the present invention generates a driving force and is coupled to a drive motor 110 having a pair of shafts from side to side and a left side of the drive motor 110. A ventilation fan 120 for providing a sound pressure to flow air into the ventilation flow path, a cooling fan 130 coupled to the right side of the driving motor 110 to provide a sound pressure to flow air to the cooling flow path; A flow path guide for guiding the flow of the fans 120 and 130 and a pair of brackets for fixing the flow path guide are included.

In detail, the ventilation fan 120 is disposed to communicate with the first exhaust port in the upper portion of the cavity 12 to discharge the polluted gas introduced into the main body 10, and the cooling fan 130. Is arranged to communicate with the intake port 86 at the upper portion of the electrical compartment 62 so that electrical components such as the magnetron 54 and the high-pressure transformer 52 can be cooled.

Meanwhile, the flow path guide includes a first flow path guide 140 for guiding the flow of air on the ventilation fan 120 side and a second flow path guide 150 for guiding the flow of air on the cooling fan 130 side. Included.

When the second ventilation outlet 154a of 150 is installed upward, the first outlet 154b faces forward, and the air discharged through the cooling outlet 154b passes through the first communication hole. It is prevented from entering the electrical equipment chamber 62 through the 63.

Therefore, when changing the position of the second ventilation outlet 154a, the cooling outlet toward the electric chamber 62 is opened, and the other two outlets are shielded by the cover member 158, thereby cooling the cooling fan. Some of the air sucked into the 130 is always moved to the electric chamber 62 side.

In addition, the air moved to the electrical equipment chamber 63 cools some electrical components of the electrical equipment chamber 63, and passes through the cavity 20 through the second communication hole 13 and the third communication hole. After being moved to the exhaust passage 84, it is finally discharged to the outside of the main body 10 through the second exhaust port 88.

Meanwhile, some of the air moved toward the upper flow path 76 cools the driving motor 110. In addition, the air moved toward the upper flow path 110 is finally discharged to the outside of the main body 10 through the first exhaust port 78 through the filter member.

As a part of the cooling passage flows into the upper passage 76, the driving motor 110 may be cooled by relatively low temperature air so that the driving motor 110 may be quickly cooled. do.

In addition, since a portion of the cooling passage is discharged to the outside after flowing into the upper passage 76, the cubic feet per minute (CFM) of the upper passage 76 is increased.

In addition, in addition to the air blown by the ventilation fan 120, a portion of the air blown by the cooling fan 130 is configured to pass through the filter member located on the upper flow path (76) The air discharged to the outside of the main body 10 is further cleaned.
