JPH06201172A - Filter for range hood - Google Patents

Abstract

PURPOSE:To provide a filter for a range hood, which can moderate the leakage of a noise. CONSTITUTION:A filter for a range hood is composed as follows, that is, it has a range hood body 4 and a filter 8. For the range hood body 4, an opening part 1 is formed on the undersurface thereof and an exhaust fan 7 having a suction port 5 forward is provided at the inside thereof. The filter 8 is opposed to the opening part 1 and the suction port 5 and is obliquely provided. Ventilating holes 9 on the filter 8 are made gradually small pointing to the lower part from above so that the more they approach the suction port 5 of the exhaust fan 7, the more they are made small.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is directed to the suction port of an exhaust blower having a front suction port provided inside the main body of a range hood having an opening formed on the lower surface and the opening on the lower surface of the main body. The present invention relates to a range hood filter provided.

[0002]

2. Description of the Related Art In recent years, along with the widespread use of range hoods, there has been an increasing demand for filters capable of preventing the noise of the blower from leaking during operation of the range hood.

A conventional range hood filter of this type will be described below with reference to FIGS. 3 and 4. As shown in the figure, an adapter 1 having an opening 11 formed on the lower surface and connected to a duct 12 communicating with the outdoors on the upper surface
3, a hood body 14 provided with a suction port 15 on the front surface and a discharge port 16 communicating with the adapter 13 on the upper surface.
The exhaust blower 17 is provided, and the exhaust blower 1 is provided.
The filter 19 is provided with the ventilation holes 18 of the same size, which are provided to be inclined and are opposed to the suction port 15 of No. 7 and the opening 11 formed on the lower surface of the hood body 14 at equal intervals.

[0004]

In the structure of such a conventional range hood filter, since the vent holes 18 of the same size are formed at equal intervals, the exhaust blower 17 is operated from the exhaust blower 17 during operation of the range hood. There is a problem that the generated noise leaks from the vent hole 18 formed in the lower portion of the filter 19 provided near the exhaust blower 17 and makes the user feel the ears.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a range hood filter capable of mitigating noise leakage.

[0006]

In order to achieve the above object, a range hood filter according to the present invention has an opening formed in the lower surface and an exhaust blower having an intake port in the front thereof is provided inside the range hood. And a filter provided to face the opening and the intake port and are inclined, and the ventilation hole of the filter is formed in order from the upper part to the lower part so that it becomes smaller as it gets closer to the intake port of the exhaust blower. It will be configured.

[0007]

According to the present invention, since the ventilation hole of the filter through which the noise generated from the exhaust blower passes when the range hood is operated is formed to be smaller toward the lower portion closer to the intake port of the exhaust blower, the noise is reduced. The lower part of the filter is more reflected than the upper part of the filter, and the noise passing through the ventilation holes in the lower part of the filter is reduced.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in the drawing, an opening 1 is formed on the lower surface, and an intake port 5 is provided on the front surface inside a hood body 4 provided with an adapter 3 connected to a duct 2 communicating with the outdoors on the upper surface. An exhaust blower 7 having a discharge port 6 communicating with the adapter 3 is provided, and a filter 8 is provided so as to face the intake port 5 of the exhaust blower 7 and the opening 1 formed on the lower surface of the hood body 4 and incline. The ventilation hole 9 is formed so as to become smaller toward the intake port 5 of the exhaust blower 7 from the upper portion to the lower portion of the filter 8, and a handle 10 is provided at the lower portion.

When the range hood is operated in the above configuration, the exhaust blower 7 is driven, air containing oil smoke is sucked through the opening 1 formed in the lower surface of the hood body 4, and oil is removed when passing through the filter 8. The air taken in through the intake port 5 of the exhaust blower 7 is sent into the adapter 3 through the discharge port 6 and is discharged outdoors through the duct 2.

A part of the noise generated from the exhaust blower 7 is dissipated from the intake port 5 toward the filter 8. The vent hole 9 provided in the filter 8 is closer to the intake port 5 of the exhaust blower 7. Filter 8 to be smaller
Since it is made smaller from the top to the bottom,
In the lower part of the filter 8, the noise is reflected and the noise passing through the filter 8 is mitigated, and the noise passes through the upper part of the filter 8 which is located farther from the intake port 5. Inlet 5 and filter 8
The space formed between the upper parts of the above becomes an air chamber, and the noise passing through the filter 8 is also alleviated.

[0011]

EFFECT OF THE INVENTION The main body of a box-shaped range hood having an opening formed on the lower surface and an air blower having an intake port in the front, and a main body of the range hood that is inclined so as to face the opening and the intake port. It is equipped with a filter, and the ventilation hole of the filter is made smaller from the top to the bottom so that it becomes smaller as it gets closer to the intake port of the exhaust blower. It is possible to provide a filter for a range hood in which the noise emitted toward the air is reduced and the noise is reduced through the filter.
