[0029] In order to make the purpose, scheme and beneficial effects of the present application more clear, the present application is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0030] The present application proposes a range hood embodiment, comprising a body and a guide plate fixed to the body. The range hood is configured to extract the oil smoke generated by cooking on a stove below. The guide plate is configured to be detachably fixed to the body. The guide plate is in the shape of a thin plate, such as Figure 1 The outer surface of the guide plate is rectangular and exposed. When the guide plate is fixed to the machine body, the guide plate is suitable for guiding the oil smoke airflow to flow into the range hood.
[0031] The machine body includes a housing 1, a fume hood 2 and an oil cup 10 which are arranged in sequence from top to bottom. Figure 1 As shown. A fan is arranged in the housing 1. The oil cup 10 is a long strip oil cup with an opening facing upward. The oil cup 10 is hung at the bottom end of the smoke hood 2 to collect the grease filtered out by the range hood. The guide plate is fixed to the smoke hood 2. Specifically, the guide plate is detachably fixed to the smoke hood 2. The smoke hood 2 is provided with a smoke collecting cavity with an opening facing forward. The guide plate is detachably fixed in the smoke collecting cavity of the smoke hood 2.
[0032] The machine body is provided with a light source. The light source is configured to project light downward. The light source is arranged on the top wall of the smoke hood 2. The light source is embedded in the smoke hood 2, with only the light-transmitting surface exposed. Figure 2 As shown. The light source is an LED lamp 3. Specifically, the number of LED lamps 3 may be one, which is in a strip shape; or the number of LED lamps 3 may be two, which are symmetrically arranged; however, it should be noted that the arrangement of the LED lamps 3 is not limited to the above.
[0033] The range hood is a side suction range hood. The guide plate is arranged to be tilted downward from front to back, and the top of the guide plate is arranged below the light source. Figure 1 and 2 Specifically, the orthographic projections of the light source and the top of the guide plate on the same horizontal plane are arranged in sequence from front to back; in other words, when a user stands in front of the range hood to cook, the light source is closer to the user than the top of the guide plate. As a result, the guide plate avoids the position directly below the light source, making it easier for the light source to project light downwards and provide lighting for the stove below.
[0034] The body is provided with an air inlet, which is located at the rear side of the guide plate, and the air inlet is provided with a filter. The guide plate completely blocks the air inlet located at the rear side thereof. Specifically, in the horizontal direction from front to rear, the guide plate completely blocks the air inlet located at the rear side thereof. An air flow channel 4 is formed between the top of the guide plate and the light source, such as Figure 1 and 2As shown. The airflow channel 4 passes through the air inlet. The left end of the guide plate is separated from the fume hood 2 to form a left oil fume channel. The right end of the guide plate is separated from the fume hood 2 to form a right oil fume channel. The left oil fume channel, the airflow channel 4 and the right oil fume channel are sequentially connected, forming a U-shaped airflow inlet as a whole, as shown. Figure 1 As shown, the U-shaped airflow inlet is formed between the guide plate and the smoke collecting hood 2, and the U-shaped opening of the U-shaped airflow inlet is arranged backward and downward. The U-shaped airflow inlet is connected to the air inlet. The bottom end of the guide plate is arranged above the oil cup 10. Since the guide plate is fixed to the body, it is inclined. Figure 1 and 2 As shown, the grease attached to the inner surface of the guide plate flows downward along the inner surface of the inclined guide plate under the action of gravity, and finally flows into the oil cup 10. When the fan is running, negative pressure is formed to generate airflow, and the outer surface of the guide plate is suitable for guiding the airflow to flow into the U-shaped airflow inlet, then into the air inlet, then upward into the casing 1, and then discharged into the common flue.
[0035] The top of the guide plate is provided with an anti-glare structure. The anti-glare structure is the end face 6 at the top of the guide plate. The end face 6 at the top of the guide plate is parallel to the light projection direction of the light source, thereby significantly reducing the glare of the end face 6 at the top of the guide plate. Specifically, the guide plate includes a glass plate 5, and the end face 6 at the top of the guide plate is integrally formed with the glass plate 5. The end face 6 at the top of the guide plate extends in the vertical direction, such as Figure 2 As shown. An upper arc transition surface is connected between the inner surface of the guide plate and the end surface 6, that is, an upper arc transition surface is connected between the inner surface of the glass plate 5 and the end surface 6. A lower arc transition surface is connected between the outer surface of the guide plate and the end surface 6, that is, a lower arc transition surface is connected between the outer surface of the glass plate 5 and the end surface 6. The upper arc transition surface and the lower arc transition surface are provided to reduce edges and corners to avoid scratching users.
[0036] The light-transmitting surface of the light source is arranged horizontally, such as Figure 2 As shown. The light source's light projection direction is vertically downward, that is, when the light source is turned on, the light emitted by it tends to be projected vertically downward as a whole. Of course, the light column generated by the vertical downward projection of the surrounding light source also has a certain amount of light extending toward the periphery.
[0037] For example, Figure 3 As shown, the present application proposes another embodiment of a range hood, wherein the guide plate comprises a metal plate 7, the top end of the metal plate 7 is bent toward the inner surface of the metal plate 7 to form a folded edge 8. The free end of the folded edge 8 is provided with a pressing edge 9. The light projection direction of the light source is as follows: Figure 3 As shown by the dotted arrow in FIG. 1 , the light projection direction is vertically downward. The upper surface of the folded edge 8 forms an angle α with the light projection direction of the light source, as shown in FIG. Figure 3As shown. α is a right angle or an acute angle. Either the upper surface of the folded edge 8 is horizontally arranged, α=90°; or the upper surface of the folded edge 8 is inclined downward from front to back, and α is an acute angle. It is precisely because the upper surface of the folded edge 8 is horizontally arranged or the upper surface of the folded edge 8 is inclined downward from front to back that the upper surface of the folded edge 8 reflects the light projected downward by the light source upward or backward, reducing the glare of the folded edge 8 itself. In addition, it should be noted that in the existing range hoods, the end surface of the top of the guide plate is most prone to glare; and in this embodiment, the top of the metal plate 7 is bent toward the inner surface of the metal plate 7 to form the folded edge 8, so that the problem of glare on the end surface itself no longer exists. Moreover, the folded edge 8 also has a certain diversion effect, which helps to improve the fume extraction effect. Furthermore, the folded edge 8 forms an acute angle with the inner surface of the metal plate 7, such as Figure 3 As shown; thus, the metal plate has a certain strengthening effect, which helps to improve the structural stability of the metal plate. This embodiment focuses on the differences from the above embodiment, and the same and similar parts of this embodiment can refer to the above embodiment.
[0038] Illustratively, the present application proposes another embodiment of a range hood, wherein the guide plate includes a metal plate 7, and the top end of the metal plate 7 is bent toward the inner surface of the metal plate 7 to form a folded edge 8. The upper surface of the folded edge 8 is configured to be suitable for reflecting the light projected by the light source in a vertically upward direction or an obliquely upward and backward direction, thereby reducing the glare of the folded edge 8 itself. In addition, it should be noted that in the existing range hoods, the end surface of the top end of the guide plate is most prone to glare; while in this embodiment, the top end of the metal plate 7 is bent toward the inner surface of the metal plate 7 to form the folded edge 8, so that the problem of glare on the end surface itself no longer exists. This embodiment focuses on the differences from the above-mentioned embodiments, and the same and similar parts of this embodiment can be referred to the above-mentioned embodiments.
[0039] The components of different embodiments may be combined with each other in any feasible manner to achieve the purpose of this application.
[0040] The above are only optional embodiments of some implementation scenarios of the present application. It should be noted that, for ordinary technicians in this technical field, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the technical concept of the present application also fall within the protection scope of the present application.
