Abstract

PURPOSE:To obviate oil sagging and to improve the efficiency of oil recovery by providing the filter which is formed by pressing a parallel punching K to a corrugated shape and is specified in opening rate with punching holes in specific positions and is provided with oil discharging holes at a rear bracket of the filter of a range hood. CONSTITUTION:The filter 2 which is formed by pressing the parallel punching K to the corrugated shape and has 19.5 to 30.5% opening rate is provided with the punching holes 1 in the positions shown in B. A rear bracket 8 of the filter is provided with the holes 11 in the case of mounting of the filter 2 to a range hood 7. As a result, the oil 10 recovered and gathered in the lower part of the filter 1 flows from the holes 11 and is fully recovered into an oil recovery container 12. Then, oil sagging does not occur any more. The efficiency of capturing the oil is improved and the cleanability is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a grease filter used in a kitchen range hood.

[0002]

2. Description of the Related Art Conventional punching filters have a drawback of causing oil dripping during use, and the disadvantages of lath net type filters are remarkable. Recently, instead of these filters, cut and raised slit type filters have begun to be used, but they have a drawback of causing clogging of the slit portion.

[0003]

The problem to be solved by the present invention is to eliminate the oil dripping of the punching filter and improve the oil recovery efficiency.

[0004]

As means for solving this problem, in the present invention, since the oil collected in the punching hole portion is collected in this portion to cause oil dripping, the punching hole By collecting the oil collected in the part in the oil recovery container more and more, the oil dripping is eliminated and the oil collection efficiency is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1 of the present invention, a parallel punching K is corrugated to form a filter 2 having an opening ratio of 19.5% to 30.5%. When oil is dripping at the position shown in FIG. 2A, oil dripping occurs, but when the punching hole 1 is provided at the position shown in B, oil dripping is eliminated and oil recovery efficiency is improved. This is confirmed by experiments. As shown in FIG. 3C, the conventional grease filter 3 has a gap at the portion 5 when two sheets are used and loses at this portion. On the other hand, the corrugated filter 2 of the present invention is used.
In the case of 1, the type is changed to E, F, and G, and the gap 5 is not generated by combining them. D is a diagram using two G types, which can be stacked like 6 and there is no need to worry about the gap 5. When using one E type,
When using three sheets, use the G type at both ends and the F type in the center. When the filter 2 is attached to the range hood 7, in the case of the filter rear catch 8, the oil collected and collected in the lower part of the filter overflows from the rear catch 8 and does not enter the oil sump 9 to the outside. It causes dripping. As a means for solving this, as shown by I in FIG. 5, a hole 11 is provided in the filter rear receiver 8 so that the oil 10 flows through the hole 11 and all the oil is recovered in the oil recovery container 12. . Figure 6
Is an oil guide 13 for the purpose of improving the oil recovery efficiency of an ordinary punching filter 14, which is made of a heat resistant silicone resin or the like, and is attached to the punching filter 14 as shown in FIG. Punching filter
14 is that the staggered type J has more oil spills, and the parallel type K has less oil spills. This is also confirmed by experiments. Further, as shown by L in FIG. 8, the slits 15 are cut in one horizontal row at the bottom of the filter 14 and the slits 15 are provided at several positions with the mouths facing downward. 14 will float and the oil 10 collected by the filter 14 will be efficiently drilled.
It is a grease filter that can collect in the oil recovery container 12 from 11. Also, the cut-and-raised slit object causes a trouble of cutting a hand during cleaning, whereas the punching type is the filter having the best cleaning property.

[0006]

The effect of the invention is to eliminate oil dripping,
It is intended to provide a grease filter having good cleanability, which maximizes the oil collecting efficiency and the oil collecting efficiency at the same time.
