[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to 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 used to limit the present invention.

[0024] Embodiment 1

[0025] The embodiment of the present invention provides an oil fume machine with a hidden filter, as Figure 1 shown, including a box body 1, a filter 2, an oil guide plate 3, a drive assembly 4 and a sliding assembly 5;

[0026] A door panel 11 and a smoke suction port are provided on the box body 1. The sliding assembly 5 is arranged on the box body 1. One end of the filter net 2 is slidably connected to the box body 1 through the sliding assembly 5 and moves up and down relative to the door panel 11 to cover the smoke suction port. One end of the oil guide plate 3 is rotatably arranged on the box body 1, and the other end is rotatably connected to the bottom of the filter net 2. The driving assembly 4 is arranged inside the box body 1 and is in transmission connection with the oil guide plate 3. The driving assembly 4 is used to drive the oil guide plate 3 to rotate and drive the filter net 2 to move up and down, so as to realize the hiding and showing of the filter net 2. An auxiliary filtering assembly 6 for assisting in removing oil stains is also arranged on the filter net 2.

[0027] In this way, when the range hood is in use, the driving assembly 4 drives the oil guide plate 3 to rotate, so that the filter net 2 moves downward relative to the door panel 11, so that the filter net 2 covers the smoke inlet, and at this time, the range hood can be operated; when the range hood stops working, the driving assembly 4 drives the oil guide plate 3 to rotate, driving the filter net 2 to move upward relative to the door panel 11, so that the filter net 2 is hidden behind the door panel 11, avoiding oil stains remaining on the filter net 2.

[0028] At the same time, an auxiliary filtering assembly 6 is also provided, which can assist in removing the oil stains accumulated on the filter net 2.

[0029] In order to collect the oil stains of the filter net 2, as Figure 1 shown, an oil receiving ring 7 is further included. The oil receiving ring 7 is arranged around the wall of the smoke inlet for collecting the oil stains of the filter net 2.

[0030] An oil cup is also included, which is arranged on the box body 1 and communicated with the oil receiving ring 7.

[0031] In this way, when the range hood is operating, the oil stains on the filter net 2 can flow into the oil receiving ring 7 or into the oil cup to be collected.

[0032] In order to assist in removing the residual oil stains on the filter net 2, as Figure 3 and Figure 4 shown, the auxiliary filtering assembly 6 includes a heating device 61. The heating device 61 is arranged on the side of the filter net 2 away from the door panel 11 to provide heat to melt the residual oil stains on the filter net 2 and flow them onto the oil receiving ring 7.

[0033] In this way, when the range hood is not working, the filter net 2 is hidden, the heating device 61 is started, and the heat melts the residual oil stains on the filter net 2 and collects them.

[0034] In order to further strengthen the removal effect of the residual oil stains on the filter net 2, as Figure 3 and Figure 4As shown, the auxiliary filtering component 6 further includes an auxiliary fan 62, and the auxiliary fan 62 is arranged on the heating device 61, that is, the auxiliary fan 62 and the heating device 61 are arranged on the filter net 2, and the heating device 61 is located between the filter net 2 and the auxiliary fan 62. The heating device 61 is a PTC heating device; the auxiliary fan 62 is used for auxiliary air intake, or the air reaches the filter net 2 after being heated by the heating device 61, so that the residual oil stains are melted and flow onto the oil receiving ring 7.

[0035] In this way, when the range hood works, the filter net 2 covers the smoking port, the auxiliary fan 62 rotates forward for auxiliary air intake, and the heating wire on the heating device 61 plays a role in secondary filtering; the filtered oil stains flow into the oil collecting cup through the oil guiding plate 3;

[0036] When the range hood does not work, the filter net 2 is hidden behind the door panel 11. At this time, the auxiliary fan 62 rotates reversely, the heating device 61 is started, the air of the auxiliary fan 62 becomes hot air after passing through the heating device 61, reaches the filter net 2, and melts the residual oil stains on the filter net 2. The residual oil stains flow onto the oil receiving ring 7 or the oil guiding plate 3 and are finally collected in the oil cup, so that the filter net is kept clean without adhering oil stains, the cleaning times of the filter net are reduced, and the beauty of the filter net is ensured.

[0037] As Figure 2 shown, the filter net 2 is of a triangular prism structure and is horizontally arranged. A first air inlet 21 is opened at the upper part of any side surface of the filter net 2, and a filter plate 22 of an integral structure extends from the upper part of the side surface close to the first air inlet 21. A plurality of second air inlets 221 for air intake are arranged side by side on the filter plate 22, and the filter plate 22 is slidably connected with the box body 1.

[0038] In this way, the filter net 2 is provided with air inlets at both the top and the side, which can integrate the advantages of side suction and top suction and improve the smoking effect.

[0039] In order to avoid generating excessive noise during the operation of the auxiliary fan 62, the bearing of the auxiliary fan 62 is a hydrodynamic bearing, which is used to reduce the fan noise.

[0040] As Figure 3 shown, the sliding component 5 includes vertical slide rails on both sides of the door panel 11, and the filter net 2 is slidably connected with the slide rails through sliders.

[0041] As Figure 1 shown, the driving component 4 includes a motor 41, and the motor 41 is arranged in the box body 1 and is connected with the oil guiding plate 3, and is used to drive the oil guiding plate 3 to rotate.

[0042] Specifically, the driving assembly 4 further includes a driving gear 42 and a driven gear 43. The driving gear 42 is arranged on the output shaft of the motor 41. The driven gear 43 is arranged in the box body 1 and meshes with the driving gear 42. The driven gear 43 is also connected to the oil guiding plate 3 and is used to drive the oil guiding plate 3 to rotate under the drive of the driving gear 42, and make the filter net 2 move up and down.

[0043] In this way, the driving assembly 4 and the oil guiding plate 3 form a rocker-slider mechanism, and the oil guiding plate 3 is the rocker. That is, the motor 41 in the driving assembly 4 drives the driving gear 42 to rotate, and the driving gear 42 makes the driven gear 43 rotate, thereby driving the oil guiding plate 3 to rotate and driving the filter net 2 to move up and down, realizing the opening and hiding of the filter net 2.

[0044] Working process: When the range hood is in use, the motor 41 in the driving assembly 4 drives the driving gear 42 to rotate, and the driving gear 42 makes the driven gear 43 rotate, thereby driving the oil guiding plate 3 to rotate and driving the filter net 2 to move downward relative to the door panel 11, so that the filter net 2 covers the smoke inlet. At this time, the range hood can be operated, and the auxiliary fan 62 rotates forward to assist in air intake. The heating wire on the heating device 61 plays a role in secondary filtration; the filtered oil stains flow into the oil cup through the oil guiding plate 3;

[0045] When the range hood stops working, the motor 41 in the driving assembly 4 drives the driving gear 42 to rotate, and the driving gear 42 makes the driven gear 43 rotate, thereby driving the oil guiding plate 3 to rotate and driving the filter net 2 to move upward relative to the door panel 11, so that the filter net 2 is hidden behind the door panel 11. At this time, the auxiliary fan 62 rotates in reverse, and the heating device 61 is started. The air from the auxiliary fan 62 becomes hot air after passing through the heating device 61, reaches the filter net 2, and melts the residual oil stains on the filter net 2. The residual oil stains flow to the oil receiving ring 7 or the oil guiding plate 3 and are finally collected in the oil cup, so that the filter net remains clean without adhering oil stains, reducing the cleaning times of the filter net and ensuring the beauty of the filter net.

[0046] When the present invention is in use, by slidably arranging the filter net in the box body and moving it up and down relative to the door panel, the filter net covers the smoking port when the range hood is working and is hidden behind the door panel when it is not working, effectively avoiding the problem of the filter net being exposed for a long time and adhering oil stains and accumulating dirt; moreover, the present invention is also provided with an auxiliary fan and a heating device, so that the range hood can assist in air intake and secondary filtration when in use, and can melt and collect the residual oil stains through hot air when the range hood is not in use, which can keep the appearance of the filter net clean and has good aesthetics; at the same time, the hidden filter net structure of the present invention is simple, easy to install and convenient to maintain.

For example, Figure 5 As shown, the driving component 4 includes a motor 41, and also includes a driving rod 44 and a connecting rod 45. The driving rod 44 is arranged on the output shaft of the motor 41. The other end of the driving rod 44 is rotatably connected with the connecting rod 45. The connecting rod 45 is rotatably connected with the filter net 2. The driving rod 44 rotates under the drive of the motor 41, drives the connecting rod 45 to rotate, thereby driving the filter net 2 to move up and down, and making the oil guide plate 3 rotate.

[0049] In this way, the motor 41 rotates, drives the driving rod 44 to rotate, thereby driving the connecting rod 45 to rotate, making the filter net 2 move up and down relative to the door panel 11, and driving the oil guide plate 3 to rotate.

[0050] Working process: When the range hood is in use, the motor 41 in the driving component 4 drives the driving rod 44 to rotate, thereby driving the connecting rod 45 to rotate, making the filter net 2 move downward relative to the door panel 11, and driving the oil guide plate 3 to rotate, so that the filter net 2 covers the smoke inlet. At this time, the range hood can be operated, and the auxiliary fan 62 rotates forward to assist in air intake. The heating wire on the heating device 61 plays a role in secondary filtration; the filtered oil stains flow through the oil guide plate 3 into the oil collecting cup;

[0051] When the range hood stops working, the motor 41 in the driving component 4 drives the driving rod 44 to rotate, thereby driving the connecting rod 45 to rotate, making the filter net 2 move upward relative to the door panel 11, and driving the oil guide plate 3 to rotate, so that the filter net 2 is hidden behind the door panel 11. At this time, the auxiliary fan 62 rotates in reverse, and the heating device 61 is started. The air from the auxiliary fan 62 becomes hot air after passing through the heating device 61, reaches the filter net 2, and melts the residual oil stains on the filter net 2. The residual oil stains flow onto the oil receiving ring 7 or the oil guide plate 3, and are finally collected in the oil collecting cup, so that the filter net remains clean without adhering oil stains, reducing the cleaning times of the filter net and ensuring the beauty of the filter net.

[0052] When the present invention is in use, by sliding the filter net in the box body and moving it up and down relative to the door panel, the filter net covers the smoking port when the range hood is working, and is hidden behind the door panel when not working, effectively avoiding the problem of the filter net being exposed for a long time and adhering oil stains and accumulating dirt; moreover, the present invention is also provided with an auxiliary fan and a heating device, so that the range hood can assist in air intake and secondary filtration when in use, and can melt and collect the residual oil stains through hot air when the range hood is not in use, which can keep the appearance of the filter net clean and has good aesthetics; at the same time, the hidden filter net structure of the present invention is simple, easy to install and convenient to maintain.
