Description

Improvement of the partial pressure plate structure of the range hood

This creation is about the improvement of the partial pressure plate structure of a range hood, especially the improvement of the partial pressure plate structure of the range hood which can improve the speed of exhausting smoke.

According to the exhaust hood, the fan is driven by the motor, and the oil smoke under the hood is sucked through two smoking ports and discharged. The range hood has two smoking ports that are exposed and not aesthetically pleasing. In order to cover two smoking outlets, a manufacturer places a partial pressure plate at a space below the smoking opening, and shields the two smoking openings from the air, so that the oil smoke enters the smoking mouth from the periphery of the partial pressure plate, such as the applicant. The patent number of the application No. M524917 "Structure of the hood structure improvement" is applied.

However, the pressure dividing plate is disposed under the smoking mouth to block the direct suction of the smoking mouth, and the oil smoke must enter from the gap between the circumferential side of the pressure dividing plate and the casing, and then collect and discharge to the smoking port, and the transition is made. The action line of the soot makes the smoke exhaustion ineffective, and only has to increase the horsepower of the motor and increase the suction. However, this has led to an increase in manufacturing costs, which has affected the market competitiveness of products and is not in line with economic principles.

In view of this, the creator has made design improvements and has created this creation.

Therefore, the main purpose of this creation is to improve the structure of the partial pressure plate of the range hood that can improve the smoke exhausting effect.

The main feature of the present invention is that a plurality of penetrating smoke inlet holes are provided on the surface of the pressure dividing plate, and the smoke inlet holes are arranged to increase the smoke exhausting speed of the range hood.

The following technical examples are given below for the technical means and structure of the present invention for achieving the above-mentioned effects.

Referring to FIG. 1 to FIG. 3, the range hood 1 of the present embodiment has a casing 10, and one side of the casing 10 has a hood panel 20, and the hood panel 20 is spaced from the casing 10. There is an internal space 30 in which an oil smoke driving unit such as a combination of a wind and stomach 31, a motor, a fan blade and the like is disposed. The hood panel 20 is provided with two smoking ports 21, which are disposed corresponding to the position of the blades.

With a partial pressure plate 40, as shown in FIG. 4 to FIG. 6 , it is disposed outside the hood panel 20 , and is disposed on the side surface facing the hood panel 20 at the left and right sides of the upper and lower ends, respectively. A fixing device 41 and a second fixing device 42 are configured to be vacantly coupled to the hood panel 20. The first fixing device 41 is provided with a clamping hole 410 for fastening with a button post 22 of a shape similar to that disposed at the end of the hood panel 20 (refer to FIGS. 2 and 3). The second fixing device 42 fixes a magnet 420 with a bracket for adsorbing and fixing the surface of the hood panel 20. The main improvement of the present invention is that a plurality of penetrating inlet holes 43 are provided on the surface of the pressure dividing plate 40, and the inlet holes 43 are for the oil smoke to pass through and enter the smoking port 21, improving the conventional knowledge. The moving line of the soot must enter through the peripheral side of the partial pressure plate, resulting in a lack of smoking effect. The arrangement of the smoke inlet hole 43 can improve the exhaust smoke effect of the range hood with the partial pressure plate.

Next, referring to FIG. 5 and FIG. 6, the pressure dividing plate 40 can be embedded by a first partial pressure plate 40a and a second partial pressure plate 40b and welded together at appropriate positions. The first pressure-dividing plate 40a is located at the end of the hood panel 20, and the first pressure-receiving plate 40a is fixed (by welding or locking) with the first fixing device 41 and the second fixing device 42. A plurality of penetrating first inlet holes 43a are disposed on the surface of the first pressure dividing plate 40a, and a first flange 44 is bent toward the second pressure dividing plate 40b at the periphery of the plate surface. The second partial pressure plate 40b has a surface area slightly larger than the first partial pressure plate 40a. The second surface of the first inlet hole 43a corresponding to the first inlet hole 43a is also provided with a plurality of penetrating second inlet holes 43b. The second inlet hole 43b is aligned with the first inlet hole 43a to constitute the aforementioned inlet hole 43, as shown in FIG. A second flange 45 is bent around the periphery of the first pressure-dividing plate 40b, and the partition space formed by the second flange 45 is just for the first pressure-dividing plate 40a. And the first folded edge 44 of the periphery thereof is embedded, as shown in FIGS. 6a and 6b, and spot welding (spot welding c) can be performed at a position where the first portion is divided, and the first partial pressure plate 40a and the second partial pressure plate 40b are Together, they form a partial pressure plate 40. The pressure dividing plate 40 is composed of the first partial pressure plate 40a and the second partial pressure plate 40b. The first partial pressure plate 40a is welded or locked to fix the welding points or the screw heads of the first fixing device 41 and the second fixing device 42. It will be completely covered by the second partial pressure plate 40b, so that the welding points or the screw heads on the first partial pressure plate 40a are completely invisible from the outside, so that the surface of the partial pressure plate 40 can be made more beautiful.

As can be seen from the above description, this creation has at least the following effects in application:

1. It can improve the exhaust smoke effect of the range hood with partial pressure plate.

2. The partial pressure plate can be made more beautiful.

In summary, this creation is not only novel, but also practical and progressive. It proposes a new type of patent application according to law, and requests patents.
