Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a ventilation shutter device designed to deal with the problem of oil dripping from the shutter plate.

(Prior Art) In conventional ventilation shutter devices, for example, ventilation fan shutter devices, oil contained in the air discharged by the blower adheres to the shutter plate, and this oil gradually flows down and drips into the house. There was a problem of staining the exterior walls of the building. To solve this problem, it is conceivable to provide a container-shaped oil receiver below the shutter plate.

(Problem to be solved by the invention) In the case of the above idea, the oil dripping from the shutter board can be collected and collected by a container-shaped oil receiver, so the problem of staining the exterior walls of the house, etc. is solved. However, when removing the oil pan to discard accumulated oil or carrying the removed oil pan, the oil pan is tilted and the oil inside spills, staining the floor etc. There was a problem.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to prevent the oil pan from being damaged even if the oil pan is tilted when removing the oil pan where oil has accumulated or when carrying the removed oil pan. The purpose of the present invention is to provide a practically superior ventilation shutter device that prevents oil from spilling.

[Structure of the invention] (Means for solving the problems) The ventilation shutter device of the invention is provided with an oil pan having a groove in a removable manner at a position below the shutter plate of the outer frame, and an oil receiver having a groove in the inside of the groove. This is characterized by forming a plurality of pleats extending in parallel with each other at small intervals.

(Function) The ventilation shutter device of the present invention receives oil dripping from the shutter plate into the grooves of the oil receiver and holds it within the minute gaps between the plurality of pleats by surface tension.

(Example) Hereinafter, an example in which the present invention is applied to a shutter device for a ventilation fan will be described with reference to the drawings. First, in FIG. 2, reference numeral 1 denotes an outer frame, in which a blower (not shown) is installed, and a plurality of shutter plates, for example, two shutter plates, are pivotally mounted on the outdoor side opening on the exhaust side so that they can be opened and closed. There is. Reference numeral 3 denotes, for example, two cushion members attached to the upper end of the lower shutter plate 2, which receive the lower end of the upper shutter plate 2 when the shutter plate 2 is closed and cushion the impact. There is. 4 is a flange formed by bending upward from the lower end of the outer frame 1, as shown in FIG.
Reference numeral 5 denotes an oil receiver, which is extruded from a soft resin and has a long shape, and has an upwardly directed groove 7 formed in its main body 6 over its entire length.
Reference numeral 8 denotes a mounting piece provided on the outside of one side wall 6a of the main body portion 6 downward from its upper end, and an insertion groove 8a is formed between this and the side wall 6a. Here, the oil receiver 5 is removably attached to a position below the shutter plate 2 by fitting the insertion groove 8a into the flange 4 of the outer frame 1, and in this attached state, both ends thereof are attached to the outer frame 1. inner wall portion 1a, 1 of
Close to a. Reference numeral 9 denotes a cushion portion provided at the rear edge of the upper end of the side wall portion 6a of the main body portion 6 on the side opposite to the mounting piece 8 (on the groove portion 7 side), and is used to attach the oil pan 5 to the outer frame 1 as described above. In this state, the lower ends of the shutter plates 2 in the closed state come into contact with each other. Reference numeral 10 denotes a plurality of pleats, which extend horizontally in parallel from the main body 6, i.e., the side wall 6a of the oil pan 5, into the groove 7 over its entire length, and between each of the pleats 10. A minute interval 11 is formed between.

Next, the operation of the above configuration will be explained.

When a switch (not shown) is turned on, a blower (not shown) starts operating, and the shutter plate 2 is opened by wind pressure, so that dirty air in the room flows along the shutter plate 2 and is discharged. The oil contained in the air adheres to the shutter plate 2.

When you turn the switch off, the blower stops and
The shutter plate 2 is closed, and the lower end portions of the shutter plate 2 abut against the cushion member 3 and the cushion portion 9, respectively, and are stopped. Then, the oil adhering to the shutter plate 2 becomes oil droplets 12 as shown in FIG. fall on top of. This oil sequentially flows down and enters the minute gaps 11 between the pleats 10, where it is held by its surface tension.

In contrast to the above, if the insertion groove 8a of the oil pan 5 is removed upward from the flange 4, the oil pan 5 can be removed from the outer frame 1.
Therefore, when discarding the accumulated oil as described above, the oil receiver 5 is removed and carried. In this case,
Although the oil pan 5 may be tilted, the oil will not spill from the oil pan 5 because the oil is held within the interval 11 between the pleats 10 due to its surface tension. Then, after discarding the oil and removing the oil by washing etc., the oil receiver 5 is attached to the outer frame 1 by fitting the insertion groove 8a into the flange 4 of the outer frame 1 again, as shown in FIG. Return to original state.

[Effects of the invention] As is clear from the above description, according to the invention, a plurality of folds extending parallel to each other at slight intervals are formed in the groove of the oil pan, so that oil flows down from the shutter plate. Oil can be held between multiple folds by surface tension, so even if the oil pan is removed from the outer frame, folded, or tilted while being carried, oil will not spill and floor surfaces will not be soiled. It has the practical effect of being possible.
