Description

Description: TECHNICAL FIELD The present invention relates to a ventilation fan commonly used for a living room that requires a grill and for a kitchen that does not require a grill.

[Conventional technology]

FIG. 4 shows a conventional ventilation fan of this type. In the figure, (1) is a main body that penetrates an outer wall (not shown) that separates the room from the outside, and (2) is the inside of the main body (1). Attached living room oil pans, (2a) and (2b) are multiple recesses formed above and below the living room oil pan (2), (2c) is a suction port, and (3) is the inside of the main body (1). A kitchen oil pan attached to, a suction port (3a), a blade (4) mounted inside the main body (1) and driven by an electric motor (not shown), and a blade (4) of the electric motor (4). Blade stoppers to prevent it from coming off from the rotary shaft (not shown) of the
A grid grill covering the front of the suction port (2c) of (2), (6a)
(6b) is a plurality of projections that are formed on the side of the grill (6) on the side of the room oil pan (2), and are fitted into the upper and lower recesses (2a) and (2b), and (7) is the kitchen oil pan (3). Is an oil sump that is connected to the lower part of the and stores the oil dripping from the kitchen oil pan (3).

In the case of a ventilation fan for a living room configured as described above, a grill that covers the front part of the ventilation fan is required in order to attach importance to the indoor landscape. Therefore, an oil sump (7) for storing the dripping oil is attached.

[Problems to be solved by the invention]

Since the conventional ventilation fan is configured as described above, it is necessary to prepare a dedicated oil pan for each of the living room and the kitchen, which causes problems such as an increase in the number of parts, complicated assembly, and high cost. there were.

In addition, there is a problem that the oil attached to the recess for mounting the grill tends to collect in that portion and is difficult to drip into the oil receiver.

The present invention has been made to solve the above problems, and an object thereof is to provide an inexpensive and easily assembled ventilation fan that does not require the preparation of dedicated oil pans for living rooms and kitchens. To do.

[Means for solving problems]

A common ventilation fan for a living room and a kitchen according to the present invention is provided with a horizontal groove in the upper part of the front surface of the oil receiver, horizontal paragraph concave parts in the lower part, and left and right vertical grooves communicating with these horizontal grooves and paragraph concave parts, and a grill. A horizontal projection fitted into the horizontal groove is provided on the upper part of the back surface, and a horizontal projection that fits into the paragraph recess is provided on the lower part of the back surface of the grill.

[Action]

In the present invention, the grill is attached when the ventilation fan is used for the living room, the grill is removed when the ventilation fan is used for the kitchen, and the oil pan connected to the oil sump is used as a common component.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. In the figure, the same reference numerals as those in FIG. 4 indicate the same or corresponding parts, (8) is an oil receiver for living room / kitchen, (8a) is an oil receiver (8)
The horizontal grooves formed on the upper part of the front surface of (8b) are the vertical grooves formed on the left and right of the front surface, (8c) is the suction port formed on the front surface,
d) is a paragraph recess formed at the lower front of the oil pan (8), (9) is a grid-like grill that covers the front of the suction port (8c), and (9a) is the upper and lower parts of the rear of the grill (9). The horizontal projection (9a) on the upper side is fitted into the horizontal groove (8a) of the oil receiver (8) to fix the grill (9) to the oil receiver (8), and The horizontal projections (9a) enter the paragraph recesses (8d) of the oil receiver (8) to position the lower part of the grill (9).

When configured as described above, when used in a room, etc., the horizontal protrusion (9a) on the upper part of the grill (9) is fitted into the horizontal groove (8a) on the upper part of the oil pan (8), and the grill (9) Horizontal protrusion (9a) at the bottom of
The grill (9) is attached to the front surface of the oil pan (8) by inserting the oil into the paragraph recess (8d) at the bottom of the oil pan (8). At this time, on the grill (9), the horizontal projection on the top has the horizontal groove of the oil receiver (8).
Since it is fitted in (8a), there is no concern that the grill (9) will come off the front of the oil pan (8) unless the entire grill (9) is moved to the front side. Also, when used for kitchen, remove the grill (9) from the oil pan (8), but when grilling fish etc. in the kitchen, oil smoke is generated, the surface of the oil pan (8), horizontal groove (8a) and Part of the oil adheres to the vertical groove (8b), but these oils are guided by the surface of the oil receiver (8) and the vertical groove (8b) to descend, and are formed in the lower portion shown in FIG. It is guided from the lower end of the oil drainer (8e) into the oil sump (7) through the recessed portion (8d).

〔The invention's effect〕

As described above, according to the present invention, the horizontal groove is provided in the upper part of the oil receiving front surface, the horizontal paragraph concave part is provided in the lower part, the vertical groove communicating with these horizontal groove and the paragraph concave part is provided on the left and right, and the above-mentioned upper part of the rear face of the grill is provided. With a simple structure in which a horizontal projection that fits into the horizontal groove is provided, and a horizontal projection that fits into the above-mentioned recessed section is provided in the lower part of the rear surface of the grill, the grill can be securely attached to the front surface of the oil receiver. Not only does it function as a grill mounting groove that allows easy attachment and detachment of the grill, but it also works effectively with or without the grill, such as when it is removed, it acts as an oil receiver that guides the oil to the oil sump. The effect that it is possible to provide the ventilation fan for the living room and the kitchen, which is easy and inexpensive to assemble, and can easily discharge the oil adhering to the groove for attaching and detaching the grill. A.
