Abstract

PURPOSE:To facilitate handling of a package for a filter set by folding a thin section part in a flat manner when a contaminated filter set is replaced, by a method wherein the thin section part is formed to the frame part of the filter set of a domestic ventilating fan to provide a hinge function. CONSTITUTION:A frame body 1 incorporates a motor horizontally supported by means of a support arm 2 and a blade 4 coupled directly to the motor, and is provided on the exhaust side of the frame body 1 with a shutter and on the suction side with a cover 6. A filter frame 9 is mounted to the front of the cover 6 in a manner to be removable by means of a lock claw 8 engaged with an engaging hole 7, and a U-shaped filter set 10 is removably mounted to the front of the filter frame 9. A thin section part 11 is formed to the filter set 10 so that a hinge function is provided for a frame part being bent to form a U-shaped fold. Thus, when the contaminated filter 10 is replaced, the filter set 10 is easily bent at the thin section parts 11 to bring it into a flat state.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ventilation fan used in the kitchen of a general household.

BACKGROUND OF THE INVENTION Conventionally, this type of ventilation fan has generally been constructed as shown in FIGS. 4 and 6, although no specific literature can be cited. A motor 102 is horizontally supported by a support arm 103 in a frame 101 that is inserted into a hole in a vertical wall (2, -7), and the motor 102 has blades 104 for sending air outside. A shutter 106 is provided on the exhaust side of the frame 101 to close when the ventilation fan is stopped.
Further, a cover 106 having a fan guide portion was provided on the intake side of the frame 101. A filter frame 107 is provided on the front surface of the cover 106, and a U-shaped filter assembly 108 for collecting oil dust is detachably provided on the front surface of the filter frame 107.

Problems to be Solved by the Invention In such a conventional configuration, when trying to replace a filter assembly that is contaminated with oil and dust, it is difficult to remove the filter assembly from the ventilation fan because the filter assembly is U-shaped. When removed, the filter assembly is bulky and difficult to carry, and the packaging of the filter assembly becomes large, resulting in increased transportation costs.

The present invention solves these problems, and aims to make the filter assembly easier to carry, reduce the packaging of the filter assembly, and reduce transportation costs.

Means for Solving the Problem In order to solve this problem, the present invention provides a U-shaped filter set that can be attached and detached to the filter frame, and this filter set has a thin wall portion on the frame portion located at the fold. It has a structure that also has a cooling function.

With this configuration, when it is time to replace the filter assembly that is contaminated with oil and dust, the filter assembly is bent at the thin part of the frame that has a cooling function, and the U-shaped filter assembly is replaced. I am amazed that it can be made flat.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, 1 is a frame that is installed by inserting it into a hole in a vertical wall, and a motor 3 is supported horizontally by a support arm 2.
and a blade 4 directly connected to a motor 3, a shutter 5 is provided on the exhaust side of the frame 1, and a cover 6 having a fan guide portion on the intake side is provided. Locking holes 7 are provided in the upper and lower parts of the cover 6. A filter frame 9 is provided on the front surface of the cover 6 and is removably attached to the upper and lower portions of the cover through locking claws 8 that engage with the retaining holes 7. A U-shaped filter set 10 that collects water is detachably provided. The filter set 1o is provided with a thin wall portion 11 in a frame portion forming a U-shaped fold in order to provide a cooling function.

With this configuration, air containing oil generated during cooking is discharged outdoors through the filter set 10, and most of the oil adheres to the filter set 1o, which is then replaced. The removed filter set 10 is folded and flattened by the thin wall portion 11 of the frame portion which has a cooling function.

As described above, according to this embodiment, the dirty filter set 10
When replacing the filter assembly 10, the effect can be obtained that the filter set 10 can be easily bent and flattened using the thin part 11 of the frame part which has a cooling function.

6.-1 Effects of the Invention From the above description of the embodiments, it is clear that according to the present invention, the frame portion of the filter assembly is provided with a thin wall portion to provide a hinge function, thereby preventing the filter assembly from becoming dirty. When replacing the filter assembly, the thin wall part of the filter assembly can be easily folded and flattened, making it easy to carry the filter assembly.Furthermore, the packaging of the filter assembly can be made smaller, reducing transportation costs. The effect is that it can be suppressed.
