Description

[Technical Field]

[0001] This application relates to the field of range hoods. [Background Technology]

[0002] In Asia, the traditional cooking method of stir-frying results in fumes with a particularly high oil content. Therefore, range hoods, used to extract cooking fumes, have become an essential household appliance. As people's demands for quality of life continue to rise, range hoods are constantly being upgraded and improved.

[0003] Currently, range hoods with smoke guide plates are increasingly favored by consumers due to their simple appearance and ease of cleaning. However, existing smoke guide plate designs still have some shortcomings. For example, traditional flat smoke guide plates have a simple structure, and air intake relies on the air intake gap formed by the interval between the smoke guide plate and the range hood body. The air intake area is limited, making it difficult to effectively guide and collect fumes, resulting in some fumes escaping and affecting the smoke extraction effect.

[0004] Unless there is sufficient evidence to support it, the prior art described herein does not imply an admission that such prior art was known to a person skilled in the art prior to the filing date of this application. [Summary of the Invention]

The outer surface of the smoke guide plate is divided into a left guide surface and a right guide surface by the air inlet. The left guide surface extends upward from left to right to the air inlet. The right guide surface extends upward from right to left to the air inlet. The oil cup is detachably suspended from the outer surface of the smoke guide plate and located below the air inlet. The oil cup is designed to collect grease dripping from the air inlet. When the oil cup is suspended on the outer surface of the guide plate, a left airflow inlet is formed between the left edge of the oil cup and the left guide surface, penetrating the air inlet. A right airflow inlet is formed between the right edge of the oil cup and the right guide surface, penetrating the air inlet. The front and / or rear edges of the guide plate are integrally formed with oil channels suitable for collecting grease from the inner surface of the guide plate.

It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application. Various embodiments may share the same view or multiple views for description, but not all features appearing in the same view should be interpreted as features that an embodiment must possess. Instead, they can be combined in any suitable manner as long as they are not technically mutually exclusive. Moreover, for the sake of brevity, different embodiments of different aspects may be presented in the same specific design; however, such presentation does not mean that embodiments of these aspects should appear together.

[0033] This application proposes an embodiment of a top-mounted range hood, comprising a housing 6 and a smoke collection hood 7 arranged sequentially from top to bottom, such as... Figure 1 and 2 As shown. This top-mounted range hood is shaped like an inverted T. A centrifugal fan is installed inside the casing 6. The smoke collection hood 7 has an open, downward-facing smoke collection chamber 8.

[0034] This embodiment of a top-mounted range hood includes a smoke guide plate 2 and an open-top oil cup 1. The smoke guide plate 2 is disposed within the smoke collection chamber 8, as shown below. Figure 1 and 2 As shown. Among them, Figure 2 This is a visual effect seen by a user standing directly in front of the top-mounted range hood and looking horizontally at it when it is suspended on the kitchen wall. From this angle, the oil cup 1 is visible, while the smoke guide plate 2 is obscured by the smoke collection chamber 8 and is not visible.

[0035] An air inlet 3 extending along the depth direction of the top-mounted range hood is provided in the middle of the smoke guide plate 2. "Depth direction of the top-mounted range hood" refers to... Figure 1 As shown by the double-headed arrow D, which is perpendicular to the kitchen wall, the air inlet 3 is elongated.

[0036] The outer surface of the smoke guide plate 2 is divided into a left guide surface 4 and a right guide surface 5 by the air inlet 3, as shown below. Figure 1 , 3 As shown in Figure 4. The left guide surface 4 extends upward from left to right to the air intake 3. The right guide surface 5 extends upward from right to left to the air intake 3.

[0037] The right edge of the left guide surface 4 and the left edge of the right guide surface 5 are positioned opposite each other, spaced apart by the air inlet 3. Both the right edge of the left guide surface 4 and the left edge of the right guide surface 5 serve as the edges of the air inlet 3. Figure 4 As shown. Specifically, the right edge of the left guide surface 4 serves as the left edge of the air inlet 3; the left edge of the right guide surface 5 serves as the right edge of the air inlet 3.

[0038] Oil cup 1, detachably suspended on the outer surface of the smoke guide plate 2 and located below the air inlet 3, is suitable for collecting grease dripping from the air inlet 3, such as... Figures 1 to 3 As shown. When the oil cup 1 is suspended on the outer surface of the guide plate 2, the left edge of the oil cup 1 and the left guide surface 4 form a left airflow inlet that penetrates the air inlet 3, and the right edge of the oil cup 1 and the right guide surface 5 form a right airflow inlet that penetrates the air inlet 3. It should be noted that "the left edge of the oil cup 1 and the left guide surface 4 form a left airflow inlet that penetrates the air inlet 3, and the right edge of the oil cup 1 and the right guide surface 5 form a right airflow inlet that penetrates the air inlet 3" is a breakthrough from the conventional understanding that "the oil cup is only used for collecting oil". This application ingeniously integrates the oil cup and the fume extraction channel together, proposing a completely new technical approach.

[0039] The left guide surface 4 extends upwards from left to right to the air intake 3; the right guide surface 5 extends upwards from right to left to the air intake 3, as shown below. Figure 1 As shown. When the centrifugal fan is running, it creates negative pressure, generating oil fume airflow. Part of the oil fume airflow flows along the left guide surface 4, passes through the left airflow inlet, then flows into the air inlet 3, then into the casing 6, flows through the centrifugal fan, and then is discharged outside the top-mounted range hood and into the common flue; part of the oil fume airflow flows along the right guide surface 5, passes through the right airflow inlet, then flows into the air inlet 3, then into the casing 6, flows through the centrifugal fan, and then is discharged outside the top-mounted range hood and into the common flue.

[0040] The front and rear edges of the smoke guide plate 2 are each integrally formed with oil guiding channels suitable for collecting grease on the inner surface of the smoke guide plate 2, such as... Figure 1 , 3 As shown in Figure 4, the oil guiding channel extends downwards and at an angle from the left and right edges of the smoke guide plate 2 toward the oil cup 1; thus, the grease in the oil guiding channel converges toward the oil cup 1 under the action of gravity. The oil guiding channel is provided with an oil leakage hole, which is located above the oil cup 1; in other words, the oil leakage hole is located at the lowest point of the oil guiding channel. This oil leakage hole is designed to allow the grease in the oil guiding channel to flow through and into the oil cup 1. The oil guiding channel is integrally formed on the inner surface of the smoke guide plate 2. Specifically, the oil guiding channel is formed on the inner surface of the smoke guide plate 2 by stamping.

[0041] Oil guiding channels, including front oil guiding channel 11 and rear oil guiding channel 12, such as Figure 3 and 4 As shown. The front oil guide channel 11 is formed at the front edge of the smoke guide plate 2. The rear oil guide channel 12 is formed at the rear edge of the smoke guide plate 2.

[0042] The outer surface of the smoke guide plate 2 connects the front oil guide channel 11 and the rear oil guide channel 12. The outer surface of the smoke guide plate 2 protrudes upwards relative to the front oil guide channel 11 and the rear oil guide channel 12 to form a smoke collection cavity, such as... Figure 1 and 4 As shown.

[0043] Both the front oil guide channel 11 and the rear oil guide channel 12 serve as the edge of the air inlet 3, such as Figure 3 and 4 As shown. Specifically, the middle region of the wall of the front oil guide channel 11 is used as the front edge of the air inlet 3; the middle region of the wall of the rear oil guide channel 12 is used as the rear edge of the air inlet 3.

[0044] Oil leakage holes, including a first oil leakage hole 13 and a second oil leakage hole 14, such as Figure 3 As shown. A first oil drain hole 13 is located in the front oil guide channel 11. A second oil drain hole 14 is located in the rear oil guide channel 12. The front end of the oil cup 1 is detachably suspended from the front oil guide channel 11. The rear end of the oil cup 1 is detachably suspended from the rear oil guide channel 12, as shown. Figure 1 As shown.

[0045] The smoke collection chamber 8 is equipped with an exhaust port. A filter screen 9 is installed at the exhaust port of the smoke collection chamber 8. A smoke guide plate 2 is located below the filter screen 9, as shown below. Figure 1 As shown.

[0046] The filter screen 9 extends downwards from the periphery towards the center, converging downwards. The lowest point of the filter screen 9 is located directly above the air inlet 3. An oil drain hole 10 is provided at the lowest point of the filter screen 9. The oil drain hole 10 is used to drain the grease adhering to the filter screen 9. It should be noted that when the centrifugal fan is operating to extract fumes, the oil fume airflow, especially the oil fume airflow flowing in from the air inlet 3, may also pass through the oil drain hole 10 and flow into the top-mounted range hood. Specifically, the filter screen 9 is made by stamping from a single piece of metal. The filter screen 9 is shaped like an inverted frustum of a pyramid, such as... Figure 4 As shown.

[0047] The filter screen 9 is shaped like an inverted truncated pyramid. The left guide surface 4 extends upward from left to right to the air inlet 3, and the right guide surface 5 extends upward from right to left to the air inlet 3. Thus, the airflow channel formed between the filter screen 9 and the smoke guide plate 2 of the top-mounted range hood gradually narrows from both ends to the middle. The middle part is provided with an air inlet 3 and an oil outlet 10 suitable for the oil fume airflow to flow through in sequence. With this combination, the smoke extraction effect is good.

[0048] Filter screen 9 has several elongated oil fume holes, such as... Figure 4 As shown, each elongated fume vent has a guide flange extending along the direction of the fume airflow. Adjacent guide flanges together form grease guiding channels. Each grease guiding channel is adapted to guide the grease filtered by the filter screen 9 towards the grease drain hole 10. The grease that gathers at the grease drain hole 10 flows through the grease drain hole 10 and drips downwards, then passes through the air inlet hole 3, and finally falls into the grease cup 1.

[0049] When the centrifugal fan is running, it creates negative pressure, generating an airflow of oily fumes. This airflow flows through the exhaust port of the smoke collection chamber 8 into the casing 6, then through the centrifugal fan, and finally exits the top-mounted range hood into the common flue. A filter screen 9 is installed at the exhaust port of the smoke collection chamber 8, which helps to significantly reduce the grease content of the oily fumes flowing into the common flue.

[0050] Oil cup 1 is elongated. Oil cup 1 extends along the depth of the top-mounted range hood, such as... Figure 1 As shown, the oil cup 1 blocks the air inlet 3 from bottom to top. However, the oil cup 1 does not completely seal the air inlet 3; the oil fumes from both sides of the oil cup 1 can flow into the air inlet 3.

[0051] The smoke guide plate 2 is a single piece. It is formed by stamping from a single sheet of metal. A flange extending upwards is formed around the perimeter of the smoke guide plate 2. The edge outline of the smoke guide plate 2 is square, as shown... Figure 1 , 3 As shown in Figure 4.

[0052] The smoke hood 7 is equipped with a fixed bracket 15, such as... Figure 4 As shown. The top of the fixing bracket 15 is fixed to the smoke hood 7. Specifically, the top of the fixing bracket 15 is provided with screw holes, and screws are passed through the screw holes to fix the top of the fixing bracket 15 to the smoke hood 7. The bottom of the fixing bracket 15 is used to detachably suspend the smoke guide plate 2. There are four fixing brackets 15. The bottom of the two rear fixing brackets 15 is used to rotatably suspend the rear part of the smoke guide plate 2; the bottom of the two front fixing brackets 15 is suitable for suspending the front part of the smoke guide plate 2 by means of a snap-fit ​​connection.

[0053] The smoke guide plate 2 and the smoke collection chamber 8 form a ring of air inlets, such as Figure 1 As shown. When the centrifugal fan is running, it creates negative pressure and generates oil fume airflow. Part of the oil fume airflow flows through the air inlet ring, then into the casing 6, through the centrifugal fan, and then is discharged outside the top-mounted range hood and into the common flue.

[0054] The oil leak hole is equipped with a support suitable for suspending the oil cup 1, such as... Figure 3 As shown. Specifically, a first support member is provided inside the first oil drain hole 13, and a second support member is provided inside the second oil drain hole 14. A first suspension member matching the first support member is provided at the front end of the oil cup 1. A second suspension member matching the second support member is provided at the rear end of the oil cup 1. The first suspension member is provided with a hook suitable for hanging on the first support member, and the second suspension member is provided with a hook suitable for hanging on the second support member. Of course, the cooperation between the first suspension member and the first support member, and the cooperation between the second suspension member and the second support member, can also refer to other existing feasible cooperation structures, such as snap-fit ​​cooperation, magnetic cooperation, etc. Furthermore, the cooperation between the first suspension member and the first support member can also be different from the cooperation between the second suspension member and the second support member. For example, the first suspension member and the first support member can adopt a magnetic cooperation, while the second suspension member and the second support member can adopt a snap-fit ​​cooperation.

[0055] Exemplarily, this application proposes another embodiment of a top-mounted range hood, wherein the filter screen 9 is in the shape of an inverted pyramid. Thus, the airflow channels formed between the filter screen 9 and the smoke guide plate 2 in this top-mounted range hood gradually narrow from both ends towards the middle, while the middle section is provided with an air inlet 3 and an oil outlet 10 suitable for the sequential flow of cooking fumes. This combination results in good smoke extraction. This embodiment focuses on illustrating the differences from the above embodiments; similar or identical parts of this embodiment can be referred to in the above embodiments.

[0056] Exemplarily, this application proposes another embodiment of a top-mounted range hood, wherein the left guide surface 4 arches upward from left to right and extends to the air inlet 3; and the right guide surface 5 arches upward from right to left and extends to the air inlet 3. This embodiment focuses on illustrating the differences from the above embodiments; for the same or similar parts of this embodiment, please refer to the above embodiments.

[0057] Exemplarily, this application proposes another embodiment of a top-mounted range hood, which is equipped with a lifting device. This lifting device is adapted to drive the smoke guide plate 2 to move up and down, so that the smoke guide plate 2 can switch between different positions. Thus, the smoke guide plate 2 can be positioned either within the smoke collection chamber 8 or moved down outside the smoke collection chamber 8. This embodiment focuses on illustrating the differences from the above embodiments; similar or identical parts of this embodiment can be referred to in the above embodiments.

[0058] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this application, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this application are intended to be illustrative and not limiting, unless explicitly stated otherwise.
