Description

[0001] The present invention relates to a range hood filter,

The present invention relates to a filter for a stove hood, and more particularly to a filter for a stove hood in which a fall preventing means is provided so as not to fall when the filter is separated from the stove hood.

In the upper part of the heating mechanism of the kitchen, a cooking hood for quickly discharging the combustion gas, smoke and odor generated during cooking to the outside of the room is provided. A filter and an exhaust fan are installed in the cooking hood so as to filter soot and harmful substances from the combustion gas, smoke and odor, and to make the outside of the apartment through a duct. A filter is detachably installed in the intake port of the cooking hood It is periodically detached and cleaned or replaced.

The conventional filter is formed in a substantially rectangular shape and includes a mesh network and a rim installed at the edge of the mesh network. The protrusion protrudes from the rim at the rear end of the filter thus formed and is inserted into a mounting hole previously formed at the edge of the intake port of the cooking hood and protruding and protruding protrusions are formed at the front end thereof to protrude the protruding protrusion, The filter is installed if it is inserted into the formed mounting hole, and if the protruding projection is retracted, the filter can be separated from the cooking hood.

However, in the above-described structure, when the filter is separated, the protruding protrusions formed on the tip end are retracted, and the protrusions formed on the rear end are used as the axis to separate the filter while pulling it downward. There is a risk that the projections formed at the rear end may fall off from the mounting hole. Recently, the use of an electric range or an induction has been increasing. If the filter is struck on a tempered glass plate used for an electric stove or an induction as described above, it can be broken and a very dangerous situation occurs. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing an example of a filter adopting a fall prevention structure according to the present invention, FIG. 2 is an excerpt showing a coupling relation between a ring and a filter frame according to the present invention, FIG. FIG. 4 is an exemplary view showing a state in which the filter is prevented from falling by the present invention. FIG.

As shown in the drawing, the filter 100 for a hood according to the present invention has a structure in which a rim 140 is wrapped around an edge of a mesh net 120 that functions to substantially filter out foreign matter. The mesh network 120 may have a substantially rectangular shape and may be made of a metal. The rim 140 is hollow and has a cross-sectional shape, and one side is formed with a slit groove in the longitudinal direction, and the mesh net 120 is fitted and fixed in the slit groove.

 In the filter 100 formed as described above, the ring 200 is formed to protrude from the rear. When the filter 100 is installed in the intake port of the cooking hood, the annulus 200 is embedded in the mounting hole 142 formed at the edge of the intake port. Accordingly, even if the filter 100 is missed due to carelessness in the process of separating the filter 100 from the intake port, the ring 200 is prevented from falling down by being caught by the installation hole 142, thereby preventing falling.

The ring 200 is fixed to the fixing hole 142 formed in the rim 140. Two fixing holes 142 may be formed in the width direction of the filter 100. However, the fixing holes 142 may be formed as many times as required according to the specifications of the filter 100. In this configuration, the ring 200 separately provided for each of the fixing holes 142 can be fixed.

On the other hand, in order to fix the ring 200 to the fixing hole 142, the structure of the support table 220 is adopted in the present invention. The support 200 is formed to be erected on the support 220. The support 220 is formed to be longer than the width of the fixing hole 142 and is fitted inward from the outside of the fixing hole 142, And the ring 200 is exposed to the outside through the fixing hole 142 in this state. The support table 220 accommodated in the frame 140 is brought into contact with both edges of the fixing hole 142 at the inner surface of the frame 140 and then the screws are fastened to the support table 220 from the outside of the frame 140, Is fixed to the rim 140, and as a result, the ring 200 is installed in the fixing hole 142.
