Description

[Detailed Description of the Invention] The present invention relates to a window ventilation fan that is improved to prevent rainwater, etc. from entering into the electrical equipment storage section.

Conventionally, in a window ventilation fan, a phase advancing capacitor for electrical components such as a motor is provided in the storage part, and the phase advancing capacitor is connected to the motor using a cord wire, but if rainwater enters the ventilation fan body, The rainwater flows down along the cord wire and intensively infiltrates into the storage section, resulting in a problem of wetting the phase advancing capacitor, resulting in low electrical safety.

Accordingly, an object of the present invention is to provide a window ventilation fan that can prevent rainwater from entering the electrical equipment housing and improve electrical safety.

An embodiment of the present invention will be described below with reference to the drawings.

1 is a ventilation fan main body; 2 is a mounting frame connected to the lower part of the ventilation fan main body 1 and attached to a window together with the ventilation fan main body 1; and 3 is a panel plate mounted on the inside of this mounting frame 2.

The ventilation fan main body 1 is composed of a main frame 4 and a cover 5 attached to the indoor side of the main frame 4, and the main frame 4 and the cover 5 have cylindrical parts 4a-95a that butt against each other and constitute a wind guide pipe 6.
The husband and wife are formed as one.

7 is a support frame integrally molded inside the cylindrical portion 4a of the main frame 4;
A motor 8 is disposed and fixed thereto, and a blower blade 9 is connected to a rotating shaft 8a of the motor 8 by a spin nut 1-10.

A protective net 11 is attached to the indoor side of the cover 5.

Reference numeral 12 denotes an oil sump container, which is stored in a storage step 5b formed at the lower part of the cover 5 so as to be accessible and removable.

13 is an insect guard attached to the outdoor side of the main frame 4.

Reference numeral 14 denotes an electrical equipment storage section, which, as shown in FIGS. 2 and 3, includes a rectangular box-shaped base frame 15 that is integrally protruded from the lower part of the main frame 4 and has an open front surface, and an opening of the base frame 15. The base frame 15 includes a front cover 16 that closes, and clamping protrusions 17, 17 are integrally provided in the base frame 15 to protrude.

A plurality of protrusions 15a are formed on the inner surface of the base frame 15 for abutting the front cover 16.

A projection 15 is provided at the tip of the upper wall 15b of the base frame 15.
A canopy-like protrusion 18 protrudes forward from the lower wall 15C, and an engagement hole 19 is formed in the lower wall 15C.

On the other hand, a retaining piece 20 is provided protruding from the lower end of the front cover 16.

The front cover 16 is opened in the base frame 15 so that the upper end of the front cover 16 is covered by the protrusion 18 by the engagement of the engagement piece 20 and the engagement hole 19 and by the screws 21. attached to the edge.

Reference numeral 22 denotes an electrical component, such as a phase advancing capacitor for the motor 8, which is provided in the electrical component housing 14 with clamping protrusions 17, 17.
It is stored in such a way that it is sandwiched between the front cover 16 and the front cover 16.

23 is an insertion hole formed in the upper wall 15b of the base frame 15;
A rising piece 24 is erected at the edge of this.

25 is a recess formed in the lower part of the support frame 7, 26 is a hooking projection protruding from the rib portion 7a of the support frame 7, and 27 is a main frame 4.
A concave portion 28 formed in the lower part of the cylindrical portion 4a is a hooking pin which is a hooking member, and the hooking pin 28 is placed in the main frame 4 at a position away from directly above the electrical component storage portion 14 and from the upper end of the rising piece 24. It is protruded from a low position.

Reference numeral 29 denotes a cord wire whose one end is connected to a terminal (not shown) of the motor 8, and the other end of which is inserted into the electrical component storage section 14 through L23 and inserted into the electrical component storage section 14. The phase advance capacitor 22 is connected to the phase advancing capacitor 22.

As shown in FIG. 2, the middle portion of the cord wire 29 is fitted into the recesses 25 and 27, and the hooking protrusion 26. Hanging pin 28. The hook is held on the rising piece 24.

Therefore, the midway portion of the cord wire 29, especially the midway portion A that is hooked and held by the hooking pin 28 in this case, is located at a position that avoids being directly above the electrical component storage portion 14, and serves as the cord wire introduction portion of the storage portion 14. It is arranged so as to be at a lower position than the rising piece 24 of.

The operation of this embodiment having the above configuration will be explained.

Now, let us consider a case where rainwater infiltrates into the ventilation fan body 1 through the window.

In this case, rainwater adhering to the ventilation fan main body 1 and the support frame 7 may flow down the cord wire 29.

Then, the rainwater flows from the high part to the low part of the cord line 29, and when it reaches part A on the way,
It is dripped from part A in the middle.

The reason for this is that the midway portion A is hooked and held by the hooking pin 29, and the cord wire 29 is held at a lower position than the rising piece 24 corresponding to the cord wire introduction portion of the electrical component storage portion 14.
This is because .

Therefore, even if rainwater runs down the cord wire 29, the electrical component storage section 1
It will not lead you to within 4.

Since the part where the rainwater drips, that is, the midway part A, is located at a position that avoids directly above the electrical component storage part 14,
The problem of dripping rainwater falling into the electrical component housing section 14 can also be eliminated, and as a whole, rainwater can be reliably prevented from entering the electrical component housing section 14, thereby improving electrical safety.

In particular, in this embodiment in which the front cover 16 is covered by the eave-like protrusion 18 formed on the base frame 15, even if rainwater directly adheres to the upper surface of the electrical component storage section 14 from outside, It is possible to prevent rainwater from entering the electrical component storage section 14, and to further enhance electrical safety.

In the above embodiment, the code wire that connects the motor 8 and the phase advancing capacitor 22 has been described, but it is of course applicable to the code wire that connects other electrical components. It goes without saying that the electrical components stored in the electrical component storage section are not limited to phase advancing capacitors, but may also be power switch devices or the like.

As is clear from the above explanation, the present invention provides a hook member at a position that avoids directly above the electrical equipment storage part of the ventilation fan body and is lower than the cord wire introduction part of the storage part. Since the hooking member is configured to hook and hold the middle part of the cord wire, it is possible to reliably prevent rainwater from entering the electrical component storage compartment, eliminating the conventional problem of electrical components getting wet with rainwater, and thereby preventing electrical A window ventilation fan that can improve safety can be provided.
