Description

Kitchen ventilation equipment {range hood}

The present invention relates to a kitchen ventilator for collecting and collecting oil generated by condensing on the surface of a housing of a blowing fan.

Generally, a ventilator for a kitchen ventilator is a type of ventilating apparatus for discharging unburned gas, food odor, and the like generated in the course of cooking using a cooking utensil such as a gas range or an electric range, A hood 10 disposed on the upper surface of the cooking utensil S and a blower fan 20 provided in the hood 10 as shown in FIG.

The hood (10) is configured to communicate with an exhaust duct leading to the outdoors, and a filter (12) is provided at the bottom of the hood (10).

Such a kitchen ventilator has an air intake function to the hood 10 side by the operation of the air blowing fan 20 so that unburned gas generated in the cooking utensil R, (10), and then escapes through the exhaust duct to the outside.

On the other hand, at the time of heating and cooking food, a so-called oil mist in which steam due to evaporation of water, volatile oil components, fine dust, etc. are mixed is generated. Such oil mist is highly viscous and highly contaminated, The air is adhered to the blowing fan 20 and the various devices disposed in the hood 10 to adversely affect operation.

Therefore, in general, the filter 12 is provided at the bottom of the hood 10 so that a considerable amount of the oil mist is filtered by the filter 12 during the intake operation, It is preferable to increase the filtration level of the filter 12 in order to reduce the suction amount of the oil mist.

However, if the filtration level of the filter 12 is increased, the problem caused by the oil mist is reduced. However, since the intake resistance due to the filter 12 is relatively increased, The filtration level of the filter 12 must be limited to a certain value in order to prevent the intake resistance from increasing.

Therefore, in the past, a filter made of a mesh metal net was used.

The filter according to the prior art has a problem in that the filter has a low filtration performance although its suction resistance is smaller than that of a filter made of other fibers due to its shape characteristics.

In order to solve the problems of the prior art, a technology has been developed in which a filter material of a fiber material is added to a metal mesh filter. According to this, filtration performance is improved by the filter material of the fiber material, but the suction resistance is relatively increased Had a problem

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art as described above, and it is an object of the present invention to provide a fuel cell system in which a filter membrane of a fiber material is partially disposed only in a region having a high air- The present invention relates to a kitchen ventilation device capable of greatly reducing problems caused by oil mist.

According to an aspect of the present invention, there is provided a kitchen ventilating apparatus comprising a hood positioned above a cooking utensil, a blowing fan provided in a fan box disposed on the upper surface of the hood to perform an intake action, And left and right filter units mounted on the bottom of the hood.

Wherein each of the filter units includes an upper and a lower mesh network disposed at a lower portion and spaced apart from each other, a frame surrounding the edges of the upper and lower mesh networks, and an intake region formed between the upper and lower mesh networks, And a partially-covering partial filter film.

The partial filter membrane may be formed of a fiber material or a paper material in the form of a flat plate.

In a state in which the left and right filter units are mounted on the hood, the filter membrane is disposed at the center of the hood.

The frame of the filter unit has a structure in which an open fitting slot is formed on one side of the frame, and the partial filter film is inserted through the open fitting slot and fitted between the upper mesh network and the lower mesh network.

The partial filter membrane is formed in a zigzag shape bent many times, and a pair of stop bars can be attached to the front ends of the filter membranes facing each other.

The frame of the filter unit may have symmetrical shapes on both sides facing each other, and a closed fitting slot having a latching hole into which the latching bar is inserted may be formed at both ends of the frame.

As described above, according to the ventilator for a kitchen according to the present invention, since filtering performance is limited only to the central portion of the hood having a large suction amount of the oil mist, the phenomenon of contamination by the oil mist is more positively prevented, There is an advantage that the usability and the use efficiency are improved by preventing the phenomenon that the resistance is lowered.

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

The kitchen ventilator according to the present invention comprises left and right filter units 30 and 30 'mounted on the bottom of the hood (see FIG. 5).

2, 3 and 4, the filter unit 30 includes upper and lower mesh nets 32 and 32 'spaced apart from each other and upper and lower mesh nets 32 and 32' A frame 34 that partially surrounds an intake region formed by the mesh nets 32 and 32 'and is interposed between the upper and lower mesh nets 32 and 32' Film 36 as shown in FIG.

The partial filter film 36 is made of a fiber material or a paper material, and is preferably in the form of a flat plate.

The frame 34 of the filter unit 30 has an open fitting slot 34a at one side thereof and the partial filter film 36 is drawn through the open fitting slot 34a, And the lower mesh network 32 (32 ').

5, when the left and right filter units 30 and 30 'are mounted on the hood 10, the partial filter film 36 mounted on each of the filter units 30 and 30' I.e., on the left and right sides of the bridge 14, respectively.

The operation of the present invention configured as described above will be described as follows.

The air suction action by the blowing fan 20 is strongest at the center of the hood 10 and becomes weak at the edge due to the characteristic of the position of the blowing fan 20 disposed at the center of the hood 10, It can be seen that a large amount is also sucked from the center of the hood 10.

Therefore, in the state that the left and right filter units 30 and 30 'are mounted on the hood 10, the partial filter film 36 is formed on the center portion of the hood 10 (left and right sides of the bridge) The filtration density of the central portion of the hood 10 is increased by the partial filter membrane 36 and the suction action of the edge is smoothly performed.

Thus, according to the present invention, filtering performance is significantly improved instead of using a filter of the conventional mesh network type, but the filter performance is greatly improved.

Compared to the prior art in which a filter membrane made of a fiber material is used in addition to the entire metal mesh filter, the intake resistance is considerably low, so that the exhaust operation can be performed smoothly.

According to another embodiment of the present invention, a zig-zag partial filter film 38 is used which is bent many times as shown in Fig. 6, and a pair of stop bars 381 are attached.

As shown in FIG. 7, the frame 34 of the filter unit 30 is formed symmetrically with respect to both sides of the frame 34 opposite to each other, and the hooks 381 and 381 ' Respectively, and hooked holes 34c and 34c 'in the form of hooks, respectively, which can be fitted to the hooks 34c and 34c'.

In another embodiment of the present invention, the method of mounting the partial filter film 38 is as follows.

First, the gap between the two engagement rods 381 is narrowed so that the partial filter film 36 is folded. Then, the one-side engagement bar 381 is inserted into one of the engagement holes 34c of the closed- So that the partial filter film 38 is unfolded by pulling the other side stop bar 381 '.

After the partial filter film 38 is opened, the other side stop bar 381 'is caught by the other side stop hole 34c'. In this way, the partial filter film 38 is kept unfolded without being folded again (See Fig. 8)

According to another embodiment of the present invention as described above, not only the filtration density is partially increased by the partial filter membrane 38 in terms of function, but also the characteristic of the partial filter membrane 38 in a zigzag shape, Will not fall significantly.

In another embodiment of the present invention, as described above, the partial filter film 38 is provided with the latching rods 381 and 381 'at both ends thereof, and is inserted into the frame 34 to be unfolded This is because the zigzag-shaped partial filter film 38 tends to be folded by itself, so that it is difficult to attach the partial filter film 38 in a simple fitting manner.

Thus, with the so-called unfolding method after the fitting, it is easy to mount the zigzag-shaped partial filter film 38, and the unfolded state after mounting is stably maintained.
