Description
Technical Field
The invention relates to a lampblack collection supporting tool which is arranged on a range hood and used for improving the lampblack collection efficiency.
Background
Fig. 17 is a perspective view showing an installation state of a conventional hood.
Referring to fig. 17, a hood 100 for collecting soot generated during cooking and discharging the soot to the outside is provided above a cooking device 120 of a cooking table 110 provided in a cooker or a kitchen. The hood 100 generally includes a hood (hood) body 101 that collects soot and guides the soot to an exhaust port, and a fan (not shown) that applies suction force to suck the soot, and is classified into a deep type (boot type), a slim type, a shallow type (flat type), and the like according to the form of the hood body. The range hood 100 shown in fig. 17 is a slim type range hood that is thin by reducing the internal volume of the funnel body 101, and is described in patent documents 1 and 2, for example. In the slim type hood 100, the flow regulating plate 103 is disposed to be spaced just below the suction port opened in the lower surface of the funnel body 101, so that the suction air speed is increased and the suction force of the soot is increased.
The deep type range hood absorbs rising oil smoke by the air funnel main body with a wide opening on the lower surface and a large inner volume. The shallow range hood can be installed even in a place with a low ceiling height by designing the arrangement or type of the fan to make the height of the air scoop body small.

Referring to fig. 1, the soot collection support tool 10 of the present embodiment is attached to a range hood 100, and the range hood 100 is installed above a cooking tool 120 such as a gas range provided on a cooking table 110 such as a cooker. Referring to fig. 2, the hood 100 is elongated in shape having a rectifying plate 103 disposed in a manner to be spaced apart from and below an inlet 102 on the lower surface of a funnel body 101. Here, the lower surface of the air scoop body refers to a region including the suction port 102. As shown in fig. 1, when the range hood 100 is disposed such that two adjacent side surfaces of the outer side surfaces of the funnel main body 101 abut against the wall surface W, the soot collection support tool 10 is disposed in a region along the remaining two side surfaces of the funnel main body 101. Alternatively, in the case where the hood 100 is a slim type having the rectifying plate 103, as shown in fig. 2, the soot collection support tool 10 is disposed outside the gap 104 formed on the outer periphery of the rectifying plate 103.
The soot collection support tool 10 includes a soot guiding member 20 and a mounting member 30 for mounting the soot guiding member 20 to the air funnel main body 101. The smoke guide member 20 is a plate-like body made of a flame retardant material such as aluminum, which is lightweight and has appropriate rigidity. More specifically, as shown in fig. 3, a rib 22 is formed on a flat plate portion 21 of the plate-like body in consideration of improvement in strength and design, and a bead 23 is provided on a peripheral edge portion. Therefore, any one surface of the flat plate portion 21 functions as a guide surface S for guiding the oil smoke to the suction port. Alternatively, the beads 23 are formed to be tapered in outer diameter at the corner portions 24 in order to fix the mounting member 30. Further, the lampblack guide member 20 of the present embodiment is constituted by a first plate-like portion 20a and a second plate-like portion 20b which are slidably combined so that the length can be adjusted. As shown in fig. 4, the first plate-like portion 20a and the second plate-like portion 20b are slidably connected by inserting the other bead 23b into the bead 23 a. Therefore, the cooking fume guide member 20 can adjust the length between the stretched state shown in fig. 3 (a) and the shortened state shown in fig. 3 (B) by sliding the first plate-like portion 20a and the second plate-like portion 20B to adjust the overlapping amount of the two.
The mounting member 30 is made of a plate-like member such as soft iron that can be plastically deformed, and in the present embodiment, as shown in fig. 5 (a), includes: a cylindrical portion 31 formed by winding one edge portion of a rectangular plate-like member with a gap 31a therebetween, a T-shaped attachment portion 32 connected to a longitudinal center portion of the cylindrical portion 31, and support piece portions 33 connected to both ends of the cylindrical portion 31. A separate space is provided in which a portion between the mounting portion 32 and the support piece portion 33 is cut out. The T-shaped mounting portion 32 has a vertically drawn portion connected to the cylindrical portion 31 and a horizontally drawn portion provided with cut-and-raised portions 32a and 32b for holding the magnet 35. The mounting portion 32 can be bent at the base of the vertically drawn portion with respect to the cylindrical portion 31.
In use, as shown in fig. 5 (B), the mounting portion 32 is bent with respect to the cylindrical portion 31, and the angle formed by the mounting portion 32 and the support piece portion 33 is set to be substantially perpendicular. Then, as shown in fig. 6, the beads 23 of the smoke guide 20 are inserted into the cylindrical portion 31 from the narrow portions of the corner portions 24 by the gap 31a of the cylindrical portion 31. Accordingly, the mounting member 30 is integrally mounted to the smoke guide 20, and the support piece 33 of the mounting member 30 abuts against the flat plate portion 21 of the smoke guide 20, whereby the posture of the smoke guide 20 can be stably maintained.
The usage procedure of the soot collection support tool 10 of the present embodiment configured as described above is as follows. First, the length of the smoke guide member 20 is adjusted by sliding the first plate-like portion 20a and the second plate-like portion 20b according to the size of the funnel body of the range hood to be attached. Next, as shown in fig. 6, (B) of fig. 5 shows, the mounting member 30 having the mounting portion 32 bent at a right angle is mounted to the smoke guide 20. Then, as shown in fig. 7, the soot collection and support tool 10 is attached to the lower surface of the air funnel main body on the outer side of the flow regulating plate by the magnet 35 of the attachment member 30. Thus, since the soot collection support tool 10 is attached to the air funnel main body 101 by the attachment member 30 in a posture in which the soot guide member 20 hangs down in the vertical direction, the guide surface S formed by one surface of the flat plate portion 21 is held in a posture (first posture) extending vertically downward from the air funnel main body.
Fig. 8 is a diagram illustrating the reason why the soot collection efficiency is improved by the soot collection support tool according to the first embodiment of the present invention. The reason why the soot collection efficiency is improved by the soot collection support tool of the present embodiment will be described with reference to the drawings.
It is estimated that the soot U1 generated during cooking rises while being diffused, and it is considered that the probability of the soot U1 reaching the range L1 where the suction force of the funnel main body 101 reaches is high as shown in fig. 8 (a). On the other hand, it is estimated that, for the soot U2 that does not reach the fixed range L1, a regular ascending airflow is rarely generated around the soot U2 and is rather in a turbulent state in many cases, and therefore, although there is a possibility that the soot U2 may linearly ascend toward the air funnel main body 101, the probability of the soot U2 curving and advancing in all directions is high. That is, conventionally, although it can be said that the soot U1 within the certain range L1 that the suction force of the hood 100 reaches can be reliably sucked, the soot U2 outside the certain range L1 cannot necessarily be sucked.
In contrast, in the range hood 100 to which the soot collection support tool 10 of the present embodiment shown in fig. 8 (B) is attached, the soot U1 'reaching the vicinity of the funnel main body 101 can reliably reach the funnel main body 101 because the traveling direction thereof is restricted by the guide surface S as long as it reaches the soot U2' of the first collection range L2 defined by the soot guide member 20. That is, according to the lampblack collection support tool 10 of the present embodiment, since the range in which lampblack can be reliably sucked can be expanded to the first collection range L2 exceeding the fixed range L1 reached by the suction force of the range hood 100, the collection efficiency of lampblack is improved.
[ second embodiment ]
Fig. 9 is a partially enlarged sectional view showing a state in which a soot collection support tool according to a second embodiment of the present invention is attached to a range hood, and fig. 10 is a view explaining a reason why soot collection efficiency is improved by the soot collection support tool according to the second embodiment of the present invention.
The soot collection support tool 10 of the present embodiment is configured to: when the mounting portion 32 is mounted to the air funnel main body 101 with the magnet 35 while the bending angle of the mounting portion 32 with respect to the cylindrical portion 31 of the mounting member 30 is increased to 180 degrees, the oily fume guiding member 20 is held in the second posture in which the guide surface S of the oily fume guiding member 20 extends horizontally outward from the air funnel main body 101.
According to the lampblack collection supporting tool of the second embodiment, the lampblack collection efficiency is also improved. The reason for this is as follows.
As shown in fig. 10 (a), when the cooking fumes U3 generated during cooking rise and reach within a certain range L3 where the suction force of the air funnel main body 101 reaches, it is considered that the probability of the cooking fumes being sucked by the range hood 100 is high. On the other hand, it is considered that the possibility that the cooking fumes U4 outside the fixed range L3 and outside the air scoop main body 101 in the horizontal direction are sucked into the air scoop main body 101 is extremely low. That is, although it is possible to reliably suck the soot U3 within the certain range L3 that the suction force of the hood 100 reaches, it is difficult to suck the soot U4 horizontally outside the air funnel main body 101.
In contrast, in the range hood 100 to which the soot collection support tool 10 of the present embodiment shown in fig. 10 (B) is attached, the soot U3 'reaching the vicinity of the funnel main body 101 is extremely likely to reach the funnel main body 101 because the traveling direction of the soot U4' located on the outer side of the funnel main body 101 in the horizontal direction is limited by the guide surface S, as long as it is within the second collection range L4 defined by the soot guide member 20 below the guide surface S. That is, according to the lampblack collection support tool 10 of the present embodiment, it is possible to increase the possibility that lampblack located on the outer side in the horizontal direction of the funnel main body 101 reaches the funnel main body 101. For this reason, it is considered that the present embodiment also improves the soot collection efficiency.
[ third embodiment ]
Fig. 11 is a partially enlarged sectional view showing a state in which a soot collection support tool according to a third embodiment of the present invention is attached to a range hood, and fig. 12 is a view explaining a reason why soot collection efficiency is improved by the soot collection support tool according to the third embodiment of the present invention.
In the lampblack collection supporting tool 10 of the present embodiment, the bending angle of the mounting portion 32 with respect to the cylindrical portion 31 of the mounting member 30 is set to 135 degrees, and when the mounting portion is mounted to the air funnel main body 101 by the magnet 35, the lampblack guide member 20 is held in the third posture in which it is inclined and extends downward and outward, so that the angle θ of the guide surface S of the lampblack guide member 20 with respect to the vertical direction is 45 degrees.
The reason why the soot collection efficiency is improved by the soot collection support tool of the third embodiment is as follows.
As shown in fig. 12 (a), when the cooking fumes U5 generated during cooking rise and reach within a certain range L5 where the suction force of the air funnel main body 101 reaches, it is considered that the probability of the cooking fumes being sucked by the hood 100 is high. On the other hand, it is considered that the possibility that the cooking fumes U6 outside the fixed range L5 and outside the lower side of the air scoop main body 101 are sucked into the air scoop main body 101 is very low. That is, although the soot U5 within the certain range L5 that the suction force of the hood 100 reaches can be reliably sucked, it is difficult to suck the soot U6 located on the lower outer side of the air funnel main body 101.
In contrast, in the range hood 100 to which the soot collection support tool 10 of the present embodiment shown in fig. 12 (B) is attached, the soot U5 ' reaching the vicinity of the funnel main body 101 is limited by the guide surface S even in the soot U6 ' located on the lower outer side of the funnel main body 101 as long as it is within the third collection range L6 defined by the soot guide member 20, and therefore the soot U5 ' is extremely likely to reach the funnel main body 101. That is, according to the soot collection support tool 10 of the present embodiment, it is possible to increase the possibility that soot located on the lower outer side of the funnel main body 101 reaches the funnel main body 101. For this reason, it can be understood that the present embodiment also improves the soot collection efficiency.
[ fourth embodiment ]
Fig. 13 is a perspective view showing a soot collection support tool and a hood according to a fourth embodiment of the present invention separately.
In the soot collection support tool 40 of the present embodiment, the soot guide member 41 attached to the air funnel main body 101 is formed in a long shape, and the bent portion 42 set in the middle is bent at a right angle to form the portions 41a and 41b corresponding to the two adjacent side surfaces of the air funnel main body 101. In this way, the smoke guide member 20 corresponding to the plurality of side surfaces of the air funnel main body 101 may be made of one member.
[ fifth embodiment ]
Fig. 14 is a perspective view showing a smoke collection support tool and a smoke exhaust ventilator of a fifth embodiment of the present invention separately.
The soot collection support tool 50 of the present embodiment is configured by a plurality of members 51a and 51c corresponding to two adjacent side surfaces of the air funnel main body 101 and a member 51b corresponding to a corner portion therebetween, and is attached to the soot guide member 51 of the air funnel main body 101. In this way, the smoke guide member 51 may be configured by a plurality of members 51a to 51c according to the size of the air funnel main body 101 and the like.
[ other embodiments ]
Fig. 15 is a perspective view showing a state in which the soot collection support tool of the present invention is attached to a deep type hood. Many deep hoods 200 do not include a rectifying plate, and most of the openings of the lower surface of the funnel main body 201 having a large internal volume are formed. The soot collection support tool 10 of the present invention can be applied to a deep type hood 200 as shown in the drawing, and thus, the soot collection efficiency is improved.
Fig. 16 is a side view showing various modifications of the lampblack guide member according to the present invention. The form of the soot guide member of the soot collection support tool can be variously modified in addition to the flat plate shape. Specifically, in the soot collection support tool 61 shown in fig. 16 (a), the cross-sectional shape of the soot guide member 61a is formed in an arc shape. Therefore, the volume of the space capable of storing the oil smoke can be enlarged. In the soot collection support tool 62 shown in fig. 16 (B), the sectional shape of the soot guide member 62a is a curved surface that is convex upward. Therefore, the volume of the space for storing the oil smoke can be enlarged. In the soot collection support tool 63 shown in fig. 16 (C), the sectional shape of the soot guide member 63a is a curved surface that is convex downward. Therefore, the volume of the space for storing the oil smoke can be enlarged. In the soot collection support tool 64 shown in fig. 16 (D), the soot guide member 64a is formed by bending a plate-like member into a triangular prism shape. This allows the guide surface to be formed by the inclined surface having high strength.
In the above-described embodiment, the smoke guide member is made of a plate-like body made of aluminum, but the invention is not limited thereto, and other metals, plastics, paper, and composite materials thereof may be used as the material. In this case, flame retardant processing may be performed as needed.
In the above-described embodiment, the attachment member is attached to the lower surface of the air scoop body by the magnet, but may be attached to the inner surface or the outer surface of the side plate of the air scoop body. In this case, the bending angle of the mounting portion with respect to the cylindrical portion of the mounting member is appropriately changed. For example, in the first embodiment, by using the mounting member in a state where the mounting portion is not bent (see fig. 5 a), the first posture in which the guide surface extends vertically downward can be obtained.
Further, the mounting member may be prepared by bending the mounting portion at a predetermined angle in advance.
In the above-described embodiment, the attachment member is configured to be attached to the air scoop body using a magnet, but an adhesive, a tape, a hook-and-loop fastener, or the like may be used as the attachment means.
Further, the soot collection support means is installed along both side surfaces of the hood, but may be installed only along either side surface. Or the oil smoke collecting and supporting tool can be arranged along three sides or more sides of the oil smoke exhaust ventilator according to the arrangement condition.
Further, the type of the hood to be installed may be any of a slim type, a deep type, a shallow type, and other forms.
In the third embodiment, the guide surface of the oil smoke guide member is inclined by 45 degrees, but the angle at which the guide surface is inclined may be set to any angle between 0 and 90 degrees depending on the installation situation or the like.
Further, the angle of the guide surface of the oil smoke guide member may be changed according to the position of the air funnel main body. For example, the guide surface may be set to be horizontal to 45 degrees and the guide surface may be set to be 45 degrees to vertical on the side of the front surface of the air scoop body in order to avoid interference with the cook.
In addition, the soot guiding member may be provided with two or more slidable portions.
[ examples ] A method for producing a compound
Examples 1 to 3 of the soot collection support tool corresponding to the first to third embodiments were prepared, and it was confirmed through experiments that the soot collection efficiency was improved in each of the examples.
[ test conditions ]
An elongated range hood (ASRL-3A-6016 LSI, manufactured by Fuji Industrial Co., Ltd.) having a rectifying plate was prepared, the left and rear surfaces of the air funnel body were partitioned by wall surfaces, and oil smoke collecting and supporting tools were attached along the open front and right surfaces, respectively. The fume guiding member is made of aluminum, and as for its outer dimension, the vertical dimension is about 11cm, and the horizontal dimension can be adjusted from about 52cm to about 89.5cm by sliding.
When the smoke guide member is attached, the smoke guide member is slid appropriately so as to adjust the horizontal dimension according to the dimensions of the front surface and the right side surface of the range hood. In addition, when the horizontal dimension of the smoke guide member is adjusted by sliding, the smoke guide member is slid so as to have the same length as the dimensions of the front and right side surfaces of the hood as much as possible, and it is considered that the smoke guide members attached to the front and right side surfaces of the hood do not interfere with each other.
For the smoke exhaust ventilator, a flame-retardant nonwoven fabric filter (weight per unit area 70 g/m)2) And a grease filter which is cut to a size of a degree of covering the grease filter and is adhered to the suction port installed right above the rectifying plate.
The gas stove is arranged below the range hood, and the frying pan is placed on the gas stove. Moreover, a dripping device for dripping water and oil is arranged on the frying pan. The distance from the upper surface of the frying pan to the lower surface of the range hood is about 70 cm.
[ test methods ]
Under the condition that the gas stove reaches the maximum fire power, water and oil are dropped to the heated frying pan through the dropping device. The dropping speed was: water 1.3 drops/sec and oil 1.0 drops/sec. The fan of the range hood is set to a "strong" mode, and the generated oil smoke is sucked through a non-woven fabric filter attached to the oil filter. This state was maintained for 20 minutes, and when 20 minutes elapsed, the heating of the wok was terminated and the operation of the range hood was stopped.
[ evaluation method ]
The weight change of the nonwoven fabric filter before and after the test was measured, and the weight of the adsorbed soot was calculated. Through evaluation, the larger the calculated weight is, the higher the oil smoke collection efficiency is.
[ test results ]
1) Example 1 (guide face vertically below): oil smoke collection amount is 7.685g
2) Example 2 (horizontal outward facing guide): oil smoke collection amount is 7.308g
3) Example 3 (guide surface inclined at 45 degrees to the lower outer side): the oil smoke collection amount is 8.584g
4) Comparative example (no soot collection support tool): oil smoke collection amount is 5.598g
[ examination ]
As is clear from the above results, the amount of soot collected by the range hood is increased in any of the embodiments by installing the soot collection support tool. In terms of the soot collection efficiency, the third posture in which the guide surface of the soot collection support tool is inclined downward and outward is preferable in example 3, and the first posture in which the guide surface is vertically downward and the second posture in which the guide surface is horizontally outward are preferable in this order in example 1. This is considered to be because the capacity of the collection range in which the hood can reliably suck the soot is maximized when the guide surface is disposed to be inclined downward and outward.
In carrying out the present invention, the third embodiment is preferably employed from the viewpoint of soot collection efficiency, but the first embodiment may be employed in consideration of ease of attachment to the range hood, reliability of maintenance of the posture of the soot guide member, and the like. In this case, a reliable improvement in the soot collection efficiency can also be obtained as compared with the comparative example.
