[0002] With the development of science and technology and the improvement of people's living standards, products such as range hoods and ventilation fans have entered ordinary people's homes. Its main function is to extract and discharge the oil smoke generated when stir-frying, grilling, and cooking food through the range hood to prevent the oil smoke from being contaminated and attached to the walls and cracks around the kitchen. During the cooking process, a small amount of oil smoke will always escape from the front and around the machine, directly invading the cook's clothes, hair, and face, not only causing damage to the facial skin, but also inducing respiratory diseases if inhaled by the human body for a long time, directly affecting the user's health. Therefore, how to effectively prevent oil smoke from escaping from the surroundings of the cooker is an urgent problem to be solved. Summary of the invention

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown, a range hood with a retractable smoke collecting plate comprises a smoke collecting plate 1, a middle plate 2 and a lower plate 3. A smoke exhaust module 4 is provided on the back of the smoke collecting plate 1. A smoking cavity connected to the smoke exhaust module is provided inside the smoke collecting plate 1. A smoke collecting port 11 connected to the smoking cavity is provided on the lower side of the smoke collecting plate, and an oil leakage port is provided at the lower end of the smoking cavity. A stove is provided on the lower plate 3.

[0034] like Figure 3 and Figure 4 As shown, the smoke collecting plate 1 includes a first panel 12, and second panels are respectively provided on both sides of the back of the first panel. The second panel includes a sliding smoke collecting plate 14. The smoking cavity 17 is arranged between the second panels on both sides, and the smoking cavity 17 is connected to the smoke exhaust module; Figure 5 As shown, the side of the sliding smoke collecting plate 14 facing the first panel 12 is provided with a concave cavity 141, and the concave cavity is connected to the smoking cavity 17. When the sliding smoke collecting plates 14 on both sides are pulled out, the concave cavity 141 becomes a new smoke collecting port, which increases the smoke collecting port and expands the smoke collecting area.

[0035] like Figure 6As shown, when the sliding smoke collecting plate 14 is stretched outward, the back of the first panel 12 is exposed, and the width of the exposed portion is equal to the sliding displacement of the sliding smoke collecting plate 14, and the exposed portion is an unobstructed open area 142. A third fixed panel 15 is provided on the back of the second panel to cover the open area, ensuring that there is no air duct gap between the inner concave cavity and the air duct of the smoking cavity, thereby ensuring the smoking effect.

[0036] Optionally, the sliding smoke collecting plate 14 is slidably connected to the first panel, or is slidably connected to the third fixed panel 15 .

[0037] Example 2

[0038] This embodiment is improved on the basis of embodiment 1. Figure 3 , Figure 4 and Figure 7 As shown, a smoke collecting port 11 is arranged on the side of the smoking chamber facing the user; a fourth panel 16 is also arranged between the second panels on both sides, and a first panel lifting drive mechanism is arranged inside the fourth panel 16. The first panel lifting drive mechanism includes racks 164 arranged on both sides of the back of the first panel; it also includes a dual-axis motor 161, which is fixed to the fourth panel through a connecting block 165, and the dual-axis motor 161 has output shafts 162 on both sides, and gears 163 are respectively arranged at the ends of the output shafts on both sides, and the gears 163 are meshed with the racks 164. When the motor rotates, the output shaft drives the gear to rotate, and the gear drives the rack to move up and down, thereby driving the first panel 12 to rise or fall. When the first panel rises, the smoke collecting port 11 is exposed; when the first panel descends to the initial position, the smoke collecting port 11 is covered.

[0039] When the user uses the range hood, the first panel is raised to expose the smoke collecting port 11. When the range hood is not in use, the first panel is lowered to cover the smoke collecting port, thereby preventing the smoke collecting port from being polluted by the external environment and being blocked.

[0040] In some optional embodiments, the dual-axis motor may also be a single-axis motor, and correspondingly, there is one rack, one output shaft, and one gear.

[0041] Optionally, the sliding smoke collecting plate 14 is slidably connected to the third fixed panel 15 .

[0042] Example 3

[0043] like Figure 2 and Fig. 9 As shown, a waste oil emulsification module is provided inside the middle plate 2, and the waste oil emulsification module includes an emulsion storage tank 27, the bottom of which is connected to an oil collecting tank 272 through an emulsion output pipe 271, and the oil collecting tank is provided inside the lower plate, and the upper end of the oil collecting tank is connected to an oil collecting funnel 274 through an oil collecting pipe 273, and the oil collecting funnel is connected to the oil leakage port. Fig.10As shown, the lower end of the smoke collecting plate smoking cavity is a funnel-shaped structure with four high sides, a low oil leakage port, and an inclination from the four sides to the oil leakage port, so that the waste oil can flow smoothly into the oil collecting funnel along the four sides. The oil smoke enters the inner cavity of the smoke collecting plate from the smoke collecting port, where the smoke is extracted through the smoke exhaust module, and the waste oil flows into the oil collecting funnel through the inner cavity of the smoke collecting plate.

[0044] like Fig. 9 and Fig.11 As shown, a first motor 2721 is arranged outside the oil collecting tank, and the output shaft of the first motor is located inside the oil collecting tank, and a spiral stirring blade 2722 is arranged on the output shaft. The bottom of the oil collecting tank is connected to the waste oil output pipeline 275. After the emulsion and waste oil flow into the oil collecting tank, the first motor rotates, driving the spiral stirring blade to rotate, thereby stirring the emulsion and waste oil, making them fully mixed, and improving the emulsification efficiency. The emulsified waste oil is discharged through the waste oil output pipeline.

[0045] By setting up the waste oil emulsification module, the waste oil can be effectively collected, emulsified and finally discharged.

[0046] In order to improve the waste oil discharge efficiency, the outer wall of the waste oil output pipeline is also connected to a flushing water inlet pipeline 278. The waste oil output pipeline is flushed by the water flow input by the flushing water inlet pipeline, thereby promoting the discharge efficiency of the emulsified waste oil and reducing the deposition of waste oil in the waste oil output pipeline.

[0047] like Figure 8 and Fig.12 As shown, the emulsion storage tank is arranged in a housing 25, and a cavity corresponding to the emulsion storage tank is arranged in the housing 25; the housing 25 is connected to the middle plate 2 through a rotating shaft, so that the housing can be turned outward to expose the upper end of the emulsion storage tank. The emulsion storage tank 27 includes a storage tank body, and a top cover 276 is arranged on the top of the emulsion storage tank, and a top cover handle 277 is arranged on the top cover 276. The top cover is movably connected to the storage tank body, for example, threaded connection.

[0048] According to this embodiment, the user can add or replace the emulsion by rotating the shell, holding the handle, and unscrewing the top cover.

[0049] The present invention is not limited to the structures which have been described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
