DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoke exhaust system for a kitchen. More specifically, the present invention relates to a smoke exhaust system for efficiently exhausting smoke generated during cooking from a range hood.

[0002]

2. Description of the Related Art Conventionally, various measures have been taken for smoke emission around a cooking range of a kitchen and the like. Generally, a range hood is arranged above a cooking range of a cooking table and cooking is performed. A method has been adopted in which oil smoke or the like generated therein is collected in a range hood and discharged outside the room by a fan.

However, in the case of a range hood, FIG.
As shown schematically, the exhaust flow (A) and the indoor air flow (B) are shown schematically, and a part of the exhaust flow easily leaks to the side of the range hood (A), and the side of the range hood (A). However, there is a disadvantage that the exhaust air flow once collected by the indoor air (B) flowing from the air leaks from the front of the range hood (A).

For this reason, as a measure for blocking the flow of air on the side of the range hood, for example, a range hood having a panel plate on a side surface, an auxiliary hood detachable from the range hood, and the like have been proposed. There is also known a hood in which two １ ／ cylindrical hoods are stacked so that the inner hood can be rotated and pulled out.

[0005]

However, in the case of the conventionally proposed range hood having a panel plate on the side surface, there is a problem that the presence of the panel plate hinders the work on the worktop. On the other hand, auxiliary hoods are detachable and can be folded and stored.However, it is not easy to put on and take off and store the auxiliary hood. It will be no different. In addition, if the panel plate and the auxiliary hood are left attached, the fire extinguishing work in the event of a fire also becomes an obstacle. Furthermore, in the case of a cylindrical hood that can be pulled out, although it is easy to store it when not in use, its cylindrical shape is not effective in blocking the side airflow, and it is not effective in actual use. Smoke efficiency is not always satisfactory.

[0006] Moreover, these smoke collecting means are all for use in the range hood itself or directly in the range hood.
There was also a problem that its application range was limited. The present invention has been made in view of the above circumstances, eliminates the disadvantages of conventional smoke exhaust equipment including a range hood, is extremely easy to store and draw out, and has excellent smoke collection performance. It aims to provide new smoke exhaust equipment.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a range hood provided with a panel guard for smoke collection which covers a lower side of a range hood disposed above a cooking range.

[0008]

In the smoke exhaust system of the present invention, a panel guard that covers the lower side of the range hood is housed in the space inside the top bag connected to the range hood, and the panel guard can be pulled down as necessary. it can. When not needed, the panel guard can be easily stored in the top bag, so that it does not hinder cooking and fire extinguishing work.

Since the panel guard is not directly attached to the range hood, it can be used with any range hood, and a panel guard with the highest smoke collection efficiency is selected according to the shape of the range hood. Can be prepared. Moreover, since a relatively large space in the top bag can be used, it is possible to provide a mechanism for lowering the panel guard and facilitating the storage operation.

An embodiment will be described below with reference to the accompanying drawings, and the smoke exhaust system of the present invention will be described in more detail.

[0011]

FIG. 1 is a perspective view showing an example of a smoke exhaust system according to the present invention. For example, as exemplified in FIG. 1, in the present invention, a panel guard (3) is disposed in a top bag (2) disposed adjacent to the left and right sides of the range hood (1) so as to be retractable and retractable. . The top bag (2) may be provided with the panel guard (3) in advance, or the panel guard (3) may be attached to an existing top bag for construction.

As a mechanism for pulling down or pulling up the panel guard (3) and storing it in the top bag (2), for example, the mechanisms shown in FIGS. 2 (a) and 2 (b) can be exemplified. That is, a handle (4) is provided at the bottom edge of the panel guard (3), the grip (5) of the handle (4) is gripped, the wire (6) is pulled, and the spring (8) is pulled through the pulley (7). Release the attached stopper (9) and pull down the panel guard (3). On the other hand, when the panel guard (3) is to be stored, the panel guard is pushed up in a state where the stopper (9) is released by also grasping the grip portion (5), and after confirming that the panel guard is completely stored, The panel guard (3) is fixed by projecting the stopper (9).

The panel guard (3) having such a stopper release mechanism is provided with a mechanism illustrated in FIG. 3, for example, in the top bag (2), so that the panel guard (3) can be lowered and stored more easily. It can be.
That is, in this example, the storage space (1) in the top bag (2) is used.
At 0), a weight (11) equal to or slightly less than the panel guard (3) is connected to the panel guard (3) by a wire (12) and suspended via a pulley (13). . Thus, even when pushing up the panel guard (3), almost no force is required. Also, when the panel guard (3) is pulled down as illustrated in FIG. 4, the operation can be easily performed with a small force due to the weight of the panel guard (3). Then, a fall prevention stopper (14) may be provided at the upper end of the panel guard (3) and the lower end of the storage space (10) so that the panel guard (3) falls to a predetermined position.

Needless to say, the stopper release mechanism and the suspension mechanism in the storage space (10) are not limited to the above examples, and various modes are possible. Also, the shape and the like of the panel guard can be selected to be efficient according to the configuration of the range hood and the entire kitchen. The material is not particularly limited as long as it is a fire-resistant material. For example, a fire-resistant glass or the like may be used to give a sense of openness.

The following is a test example in which the smoke exhaust efficiency of one embodiment of the present invention and the conventional equipment as a comparative example are compared with each other in the exhaust gas smoke collection efficiency. That is, as an embodiment of the present invention, a smoke exhaust system was configured as illustrated in FIG. The panel guard (3) used was a right-angled isosceles triangle, and the positional relationship with the range hood (1) and the cooking range (15) and dimensions were as shown in FIG.

Further, as a comparative example, a configuration in which the panel guard (3) was removed from the configuration of FIG. 5 was used. In the smoke exhaust system as described above, the collection efficiency of the exhaust gas from the cooking range (15) was measured over time in the range hood (3). The results are as shown in FIG. 6. In the case of the comparative example without the panel guard (3), the exhaust gas collection efficiency was 83% on average, while the lower side of the range hood (1) was covered. In the embodiment of the present invention provided with the triangular panel guard (3), it was confirmed that exhaust gas could be collected with a high efficiency of 95%. This is because the range hood (1) is controlled by the panel guard (3) as shown in FIG.
The inflow of room air from the side of the hood decreases, and the inflow of air from the front of the range hood (1) instead increases, so that the exhaust flow (A) is pushed back and flows out of the range hood (1). This is because it becomes difficult. Of course, the panel guard (3) is also effective in preventing the exhaust flow (A) from flowing out from the side of the range hood (1).

[0017]

As described above in detail, according to the present invention, there is provided a new smoke exhaust system which is extremely easy to store and withdraw, can be applied to any range hood, and has excellent smoke collecting performance. You.
