Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a lower filter support portion in which an oil receiver is disposed in a horizontally elongated manner at the lower part of the hood body, and a filter is formed in the oil receiver. and an upper filter support part provided at the upper part of the hood body.

[Technical background of the invention]

Traditionally, this type of range hood fan has a horizontally long oil receiver with a concave cross section,
An L-shaped receiving piece is positioned near the front wall and fixed thereto, and the front wall of the oil receiver and the receiving piece constitute a lower filter support portion. The lower end of the filter is supported between the front wall of the oil receiver and the receiving piece.

[Problems with background technology]

However, in the above configuration, since the lower end of the filter abuts against the front wall of the oil receiver over its entire length, a long groove is formed by the front wall of the oil receiver and the lower end of the filter. Oil that has flowed down from the filter tends to accumulate in this groove, so if it is used for a long period of time, the oil that has accumulated in this groove will overflow from the front wall of the oil receiver and drip onto the cooking table, microwave, etc. below. Not only did it stain them, but it also dripped into the cooking utensils during cooking, which was unsanitary.

[Purpose of invention]

Therefore, an object of the present invention is to provide a range hood fan in which no groove is formed between the oil receiver and the lower end of the filter, thereby preventing oil flowing down from the filter from overflowing from the oil receiver. It is in.

[Summary of the idea]

In the present invention, the lower filter support part is configured such that the filter lower end abutting part is separated from the inner wall surface of the oil receiver and both ends are open on the oil receiver. The groove is spaced apart from the inner wall surface of the oil receiver, and both ends of the groove formed between the lower end of the filter and the lower filter support are opened on the oil receiver.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 1, 1 is a hood main body, which consists of a box 2 whose front and bottom surfaces are open and a front hood 3 attached to the front of this box 2 by screws, for example. 2 and the front hood 3 form an intake port 4 on the lower surface of the hood main body 1. This hood main body 1 is located in a kitchen and is attached to a room wall 5 so as to be located above a range (not shown) placed on a cooking table. A blower device 10 is provided, which includes an attached outer frame 6, a fan 7 and a motor 8 disposed within the outer frame 6, a shutter 9 for opening and closing an exhaust port 6a formed in the outer frame 6, and the like. . Reference numeral 11 denotes a receiving piece portion curved at the upper front side of the box body 2 of the hood main body 1 so as to face diagonally downward to the rear side, and on the upper surface of this receiving piece portion 11 is an elastically deformable presser piece portion 12 made of, for example, a leaf spring. The receiving piece 11 and the holding piece 1 are fixed together.
2 constitutes an upper filter support portion 13. On the other hand, reference numeral 14 denotes an oil receiver disposed at the lower part of the inner side of the hood body 1, which is formed in the shape of an oblong box with an open top surface, and an oil drain hole 15 is formed in the bottom of the oil receiver. An oil sump container 16 is located in the lower part of 15.
is arranged in a removable manner. Now, 17 is a lower filter support part, and as shown enlarged in FIGS. 2 and 3, the upper piece part 17a is connected to the lower part 17.
The lower piece portion 17 is formed in a U-shaped groove shape that is longer than b.
b is fixed to the inner surface of the front wall of the oil receiver 14,
Therefore, in this embodiment, the lower filter support portion 17
is formed so that the filter lower end abutting part 18 located at the lower part of the lower piece part 17b is spaced from the inner surface of the front wall of the oil receiver 14, and both ends are open on the oil receiver 14, Furthermore, it is formed narrower than the lower end portion of the filter 19, which will be described later. Note that a plurality of filter support portions 17 exist in the longitudinal direction of the oil receiver 14 (however, only one is shown). Reference numeral 19 denotes a filter having a raised piece 19a bent slightly toward the front at its lower end, the upper end of which is elastically held between the receiving piece 11 and the holding piece 12 of the upper filter support part 13. , the lower end portion is inserted into the lower filter support portion 17, and the tip of the raised piece portion 19a is abutted against and supported by the filter lower end contact portion 18, so that the filter 19 can be inserted into and removed from the hood main body 1 in a forward-inclined state. Equipped with possible. In the installed state of the filter 19, the filter 1
The lower end of the oil receiver 9 is spaced apart from the inner surface of the front wall of the oil receiver 14 and located on the oil receiver 14 .

Next, the operation of the above configuration will be explained. When the oil adhering to the filter 19 flows down to the lower end of the filter 19, the oil flows from the lower end of the filter 19 into the oil receiver 14 at the part of the lower end that is detached from the lower filter support part 17. Fall directly. On the other hand, the oil that has flowed down to the part of the lower end of the filter 19 that is received by the lower filter support part 17 is temporarily received by the lower filter support part 17; Since both ends are open above the oil receiver 14, the oil flows laterally within the lower filter support 17,
The oil falls into the oil receiver 14 from the open ends of the lower filter support 17 . As a result, even if a groove is formed by the lower piece portion 17b of the lower filter support portion 17 and the lower end portion of the filter 19, oil is prevented from accumulating in the groove unlike in the past. That is, in the conventional configuration, the lower end of the filter was in contact with the front wall of the oil receiver, so the lower end of the filter and the front wall of the oil receiver caused a long length to be formed over the entire length of the lower end of the filter. However, in this embodiment, the groove formed by the lower filter support part 17 and the lower end of the filter 19 is smaller than the end of the filter 19. short,
Therefore, the oil flowing down into the groove flows laterally and reaches the open ends of the lower filter support part 17 in a relatively short time, so the oil does not accumulate in the groove and flows into the lower filter support part 17. It quickly falls into the oil receiver 14 from the open ends. The oil received in the oil receiver 14 as described above finally drips from the oil drain hole 15 and is collected in the oil sump container 16.

[Effect of idea]

As is clear from the above description, the present invention includes an oil receiver disposed in a horizontally elongated manner at the lower part of the hood body, and a filter is connected to a lower filter support portion formed in the oil receiver and inside the hood body. In the range hood fan installed and supported by an upper filter support part provided on the upper part of the oil receiver, the lower filter support part is spaced apart from the inner wall surface of the oil receiver, and both ends of the lower filter support part are separated from the inner wall surface of the oil receiver. Since it is shaped to open on the oil receiver, a groove is not formed between the oil receiver and the lower end of the filter, and the oil that has flowed down from the filter can be prevented from overflowing from the oil receiver. This has excellent practical effects.
