At the same time, because Chinese families have the habit of frying and cooking, a lot of oil smoke is generated when cooking, so the range hood has become one of the indispensable kitchen equipment for ordinary families, and the smoke extraction effect and easy cleaning of the range hood have also become the key points that home users pay special attention to.

[0003] However, most of the existing range hoods are T-shaped, and the T-shaped range hoods have the following main problems: since the oil smoke generally enters the range hood from the bottom and is then discharged, some grease will condense on the surface of the oil net after long-term use. If it is not cleaned for a long time, oil droplets may drip from the oil net onto the stove or even into the pot. At the same time, the T-shaped range hood with poor exhaust effect will also cause the wall to be covered with grease, making it difficult to clean. Summary of the invention

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0028] Embodiment 1 of the present invention provides a concealable oil screen, such as Figure 1 As shown, it includes a sliding flip structure 1, a filter assembly 2 and a frame 3, wherein the sliding flip structure 1 is arranged in the frame 3, and the filter assembly 2 is rotatably connected to the sliding flip structure 1. The sliding flip structure 1 can drive the filter assembly 2 to flip downward and unfold to increase the depth of the smoking chamber, and flip upward to store the filter assembly 2 into the frame 3.

[0029] Among them, the oil condensing plate 12 is mainly used to block oil smoke, collect oil and guide oil; the filter assembly 2 is mainly used to filter oil smoke, increase the air intake area and guide oil.

[0030] In this way, by adopting the above structure, the present invention comprises a concealed oil net composed of a filter assembly 2 and a sliding flip structure 1. When the filter assembly 2 is flipped downward and opened, it can not only increase the air intake area to facilitate filtering of oil fumes, but also move the negative pressure area downward, closer to the oil fumes, and absorb the oil fumes faster. At the same time, the oil condensing plate 12 can block the oil fumes from escaping backwards and protect the wall from being soiled by the oil fumes. In addition, since the back of the oil condensing plate 12 does not contact the oil fumes, when the filter assembly 2 is flipped upward and closed, there is no grease adhesion, the number of cleaning times is greatly reduced, and the user experience is improved.

[0031] The sliding flip structure 1 includes a sliding component 11 and an oil condensing plate 12. The sliding component 11 is vertically arranged in the frame 3 along the up and down direction. One end of the oil condensing plate 12 is pivotally connected to the frame 3, and the other end is rotatably connected to one end of the filter component 2. The other end of the filter component 2 is arranged on the sliding component 11 and can slide along the direction of the sliding component 11.

[0032] The sliding assembly 11 includes a sliding rail and a sliding block. The sliding rail is vertically arranged in the frame 3. The sliding block is slidably arranged in the sliding rail and is connected to one end of the filter assembly 2. The sliding flipping structure 1 also includes a driving unit. The output end of the driving unit is connected to the oil condensing plate 12 for driving the oil condensing plate 12 to rotate. The oil condensing plate 12 drives the filter assembly 2 to flip up and down. The driving unit is a motor assembly.

[0033] The oil condensing plate 12 is bent inward at the connection with the filter assembly 2 to form an oil collecting angle 13, and the filter assembly 2 is bent inward at the connection with the oil condensing plate 12 to form an oil guiding angle 21. The bending angle of the oil guiding angle 21 is 122° (range 100°-140°), which fully ensures that the filter assembly 2 guides the grease away in the open or closed state. In the open state, the oil condensing plate 12 blocks the fumes from escaping backwards and protects the wall from being stained by the fumes; in the closed state, the back does not contact the fumes, so there is no grease adhesion, the number of cleaning times is greatly reduced, and the user experience is improved; the bending angle of the oil collecting angle 13 is 45° (range 30°-80°), which is used to catch the grease flowing down from the filter assembly 2 and prevent the grease from dripping to the outside of the range hood.

[0034] When the oil condensing plate 12 is in a closed state, it can catch the dripping oil of the filter assembly 2, and the oil collecting angle 13 can prevent the grease from flowing out of the oil condensing plate 12. When the oil condensing plate 12 is turned up and reaches a stable state, it tilts upward and forms an oblique angle with the horizontal plane (in the range of 30°-60°), so that the grease dripping onto the oil condensing plate 12 can be discharged.

[0035] The filter assembly 2 is one of an arc filter, an oblique straight filter and a conical filter.

[0036] like Figure 2As shown, when the filter assembly 2 is an arc-shaped filter, the cross-section of the filter is an arc-shaped one, because the arc distance between two points is the longest. Compared with the square filter of the previous T-type machine, the arc-shaped filter increases the air intake area and improves the air intake volume.

[0037] like Figure 3 As shown, when the filter assembly 2 is an oblique straight filter, the cross section of the filter is a straight line.

[0038] like Figure 4 As shown, when the filter assembly 2 is a conical filter, the cross section of the filter is conical.

[0039] The enclosing plate 4 is also included. The enclosing plate 4 is arranged on both sides of the filter assembly 2 to collect smoke, forming a small smoke collecting cavity, and secondary smoke collection to prevent oil smoke from escaping. The bottom shape of the enclosing plate 4 is adapted to the shape of the filter assembly 2, and the top shape is triangular and when the filter assembly 2 is turned down, it abuts against the oil condensing plate 12 to collect smoke.

[0040] When the present embodiment is in the open state, the driving unit works, the oil condensing plate 12 rotates backward, and flips the filter assembly 2 down, so that the filter assembly 2 extends downward, is closer to the oil smoke, and absorbs the oil smoke faster. The oil condensing plate 12 moves the negative pressure area downward, and absorbs the oil smoke faster, preventing the oil smoke from escaping and enhancing the smoking effect. When the present embodiment is in the closed state, the driving unit works, the oil condensing plate 12 rotates forward, and flips the filter assembly 2 upward. The oil condensing plate 12 finally tilts upward and maintains a state of being at an oblique angle to the horizontal plane, and then guides the grease on the filter assembly 2 to the oil condensing plate 12 through the oil guide angle 21, and the grease on the filter assembly 2 is caught by the oil collecting angle 13 on the oil condensing plate 12 and the grease is discharged through the inclined oil condensing plate. Example

[0041] like Figure 5-8 As shown, Embodiment 2 of the present invention provides a range hood, which includes the concealable oil net and frame 3, a fan assembly, a smoke collecting chamber 5, an oil receiving assembly 6 and an oil cup 7, wherein the fan assembly is arranged inside the frame 3, the smoke collecting chamber 5 is arranged below the frame 3, the oil receiving assembly 6 is arranged in the frame 3 and below the fan assembly, the sliding and flipping structure 1 is installed on the inner wall of the frame 3, the oil cup 7 is arranged at the lower edge of the frame 3 for receiving the oil stains condensed when the concealed oil net is received in the frame 3, and the other end of the oil receiving assembly 6 is connected to the oil cup 7.

[0042] The oil receiving assembly 6 includes an oil receiving box and an oil outlet pipe. The oil receiving box is installed inside the frame 3 and is located below the fan assembly. The oil receiving box is connected to the oil cup 7 through the oil outlet pipe.

[0043] In the present embodiment, when the range hood is started, the driving unit works, the oil condensing plate 12 rotates backward, and the filter assembly 2 slides down and flips down along the slide rail, so that the filter assembly 2 extends downward and is closer to the oil smoke, and the oil smoke is sucked away faster. The oil condensing plate 12 moves the negative pressure area downward, and the filter assembly 2 is like an accelerated rising slide rail, so that the oil smoke is accelerated to rise when it hits the filter assembly 2, and a large amount of oil smoke is sucked away in a concentrated manner. The smoke collecting hood only needs to hold a small amount of oil smoke, so the two cooperate with each other to prevent the oil smoke from escaping and enhance the smoking effect.

[0044] When the range hood is turned off, the drive unit works, the oil condensing plate 12 rotates forward, the filter assembly 2 moves upward along the slide rail, the oil condensing plate 12 covers the bottom of the range hood and tilts upward to maintain an oblique angle with the horizontal plane. The oil condensing plate 12 can not only catch the dripping oil of the filter assembly 2, but also catch the grease that drips from the oil collecting box on the top of the range hood and cannot be caught, and guides the grease on the filter assembly 2 and the oil condensing plate 12 to the oil cup 7. In addition, since the back of the oil condensing plate 12 does not contact the oil smoke, there is no grease adhesion. Compared with the traditional T-type machine, the number of times the filter and the smoke collecting chamber are cleaned is reduced, thereby improving the user experience.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
