Description

Technical Field

[0001] The invention belongs to the technical field of range hoods, and in particular relates to a side-suction range hood. Background Art

[0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Usually, range hoods include top suction type and near (side) suction type. The near suction type range hood uses the principle of vortex wind pressure to absorb most of the oil smoke close to the stove in an arc form, which can reduce the adverse effects on human health.

[0003] Current close-suction range hoods, such as the Chinese utility model patent "A Close-Suction Range Hood", whose patent number is ZL201721290314.5 (authorization announcement number is CN207539970U), disclose a close-suction range hood, including a shell and a fan system, the shell includes a panel located at the front end and inclined to the horizontal direction, the panel is provided with an opening to become the air inlet of the range hood, the front side of the panel is provided with a smoke screen, the smoke screen is rotatably connected to the upper part of the panel, so that the smoke screen can rotate outward to open the air inlet of the range hood or rotate inward to close the air inlet of the range hood.

[0004] The above patent has the following defects:

[0005] After the smoke damper opens the air inlet, the top edge of the smoke damper is higher than the top of the box body, and a cabinet is usually installed on the top of the box body. At this time, the top edge of the smoke damper is easy to interfere with the bottom of the cabinet or the door of the cabinet. For this reason, a certain gap is left between the top of the box body and the bottom of the cabinet. The existence of the gap makes it easy for dust to accumulate and is difficult to clean, which brings inconvenience and cleaning problems to users.

[0006] Therefore, it is necessary to further improve the existing close-suction range hood. Summary of the invention

[0007] The first technical problem to be solved by the present invention is to provide a side-suction range hood in which the top edge of the smoke baffle is not higher than the top of the box body after the air inlet is opened, in view of the current status of the above-mentioned prior art.

[0008] The second technical problem to be solved by the present invention is to provide a side-suction range hood that keeps the smoke baffle plate stable after the air inlet is closed.

[0009] The third technical problem to be solved by the present invention is to provide a side-suction range hood that prevents the smoke baffle from shaking after the air inlet is fully opened.

[0010] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a side-suction fume suction device, comprising:

[0011] A housing having an air inlet in an upper area of ​​a front side thereof;

[0012] a smoke shield, arranged at a position of the housing corresponding to the air inlet, and arranged to be able to rotate forward relative to the housing to open the air inlet or rotate backward relative to the housing to close the air inlet, wherein when the air inlet is in a closed state, the top edge of the smoke shield is located below the top surface of the housing or is flush with the top surface of the housing;

[0013] It is characterized by also including:

[0014] A linkage member, located behind the smoke baffle, and mounted on the housing via a mounting shaft extending in the left-right direction;

[0015] A driving assembly, used to drive the linkage member to rotate around the axis of the mounting shaft, wherein the power output end of the driving assembly is rotationally connected to the power input end of the linkage member, the rotation center of the rotation connection between the driving assembly and the linkage member is point D, and the rotation center of the rotation connection between the linkage member and the housing is point E;

[0016] A connecting rod is located behind the smoke shield, a first end of which is rotatably connected to the smoke shield, a second end of which is rotatably connected to the linkage member, and a rotation center is F, and the rotation centers D, E and F are three vertices of a triangle. The connecting rod moves forward and backward under the drive of the linkage member to rotate the smoke shield forward and backward; and

[0017] The movable rod is located behind the smoke shield and gradually tilts backward from top to bottom. The lower end of the movable rod is installed on the mounting shaft and can rotate around the axis of the mounting shaft. The upper end of the movable rod is rotatably connected to the smoke shield through a connecting shaft extending along the left and right directions. The connecting shaft is located above the first end of the connecting rod.

[0018] The driving component can be in the form of a motor or an electric push rod, but preferably, the driving component is an electric push rod mechanism, which includes a push rod housing and a push rod that performs linear reciprocating motion relative to the push rod housing, the free end of the push rod is rotatably connected to the linkage member, the end of the push rod housing away from the push rod is rotatably connected to the casing, and the rotation center of the rotational connection between the push rod and the linkage member is D.

[0019] The linkage member may be in the form of an arc rod or a circular plate structure, but preferably, the linkage member is a polygonal rotating plate, and the rotation centers D, E and F are respectively located at corresponding corners of the rotating plate.

[0020] The movable rod is a straight rod.

[0021] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: the movable rod and the linkage are arranged along the left-right direction, and the lower part of the movable rod is provided with an extension part which limits the rotation of the linkage and then limits the backward movement of the connecting rod, and the extension part extends in the direction of the linkage, and when the air inlet is in a closed state, the extension part is located under the linkage and is against the linkage.

[0022] In order to filter the oil smoke, the casing has a chamber inside, in which an inner panel is arranged side by side with the surface where the air inlet is located, a filter is installed on the inner panel at a position corresponding to the air inlet, and the inner panel is provided with a through groove for at least the movable rod to pass through.

[0023] The surface where the air inlet is located can be arranged vertically or inclined. However, in order to absorb most of the oil smoke close to the stove in an arc form, the surface where the air inlet is located gradually tilts backward from top to bottom.

[0024] In order to keep the left and right sides of the smoke shield synchronized during rotation, the connecting rod and the linkage member form a transmission mechanism, which has two groups and is respectively arranged on the left and right sides of the smoke shield, and the mounting shaft is passed through the linkage members of the two groups of transmission mechanisms.

[0025] In order to reliably keep the top edge of the smoke shield unchanged when the air inlet is in the open state, a limiter is also included to limit the upper end of the movable rod from rotating downward. When the air inlet is in the open state, the limiter abuts against the corresponding position of the movable rod. Thus, the existence of the limiter prevents the upper end of the movable rod from continuing to rotate downward, that is, it cannot drive the smoke shield to continue to move downward, and keeps the height of the top edge of the smoke shield unchanged.

[0026] In order to adjust the opening of the smoke shield according to actual needs, when the air inlet is in the open state, the smoke shield has a first position and a second position. When the smoke shield is in the first position, the lower end of the smoke shield swings forward to reach the second position. In this way, when the smoke shield is in the second position, the air inlet is in a fully opened state; in addition, when the smoke shield is in the first position and the second position, the height of the top edge of the smoke shield remains unchanged.

[0027] The technical solution adopted by the present invention to solve the third technical problem is as follows: the movable rod and the linkage are arranged in sequence along the left-right direction, the linkage is provided with a convex portion extending in the direction of the movable rod, the convex portion is located on the movable rod, and when the smoke baffle is in the second position, the linkage rotates until its convex portion abuts against the position of the movable rod located on the mounting shaft. The existence of the aforementioned limit portion prevents the upper end of the movable rod from continuing to rotate downward, and the existence of the aforementioned convex portion prevents the upper end of the movable rod from continuing to rotate upward, thus ensuring that the movable rod is in a stable state, thereby ensuring that the smoke baffle does not shake, and when the range hood is working, the smoke baffle does not shake due to the influence of the oil smoke airflow.

[0028] There are many structural forms of the linkage, which can be in the form of an arc rod, a circular plate, or a polygonal plate. However, preferably, the linkage is a polygonal rotating plate, and the convex portion is formed on the first side edge of the rotating plate. In order to keep the smoke shield stable after the air inlet is closed, the movable rod and the linkage are arranged along the left-right direction, and the lower part of the movable rod is provided with an extension portion that limits the rotation of the linkage and then limits the backward movement of the connecting rod. The extension portion extends in the direction of the linkage. When the air inlet is in a closed state, the extension portion is located below the rotating plate and abuts against the second side edge of the rotating plate away from the first side edge.

[0029] In order to make the smoke shield more stable when the smoke shield is in the second position, the rotation center of the first end of the connecting rod rotatably connected to the smoke shield is A. When the smoke shield is in the second position, the connecting rod is arranged along the length direction of the connecting line AE.

[0030] There are many structural forms of the limiting part, but preferably, the housing is provided with a mounting plate arranged vertically and along the front-to-back direction, the movable rod is located between the linkage member and the mounting plate, the mounting shaft is installed on the mounting plate, the limiting part is formed on the mounting plate and protrudes toward the movable rod, the first part of the movable rod below its mounting shaft is located below the limiting part, and when the air inlet is in the open state, the first part abuts against the limiting part. The mounting plate is formed with a mounting hole for the mounting shaft to be inserted therein, the aforementioned limiting part can also be a protrusion formed on the inner circumference of the mounting hole, and the mounting shaft is provided with an arc groove extending along its circumference for the protrusion to slide and limit therein.

[0031] In order to facilitate the installation of the fan in the range hood and improve the aesthetics, the inside of the casing is provided with a chamber connected to the air inlet, the mounting plate is located in the chamber and is arranged side by side with the left and right side wall panels of the casing, the top of the mounting plate is connected to the top wall of the chamber, and the limiting portion is formed on the rear edge of the mounting plate.

[0032] Compared with the prior art, the advantages of the present invention are: the side-suction range hood drives the lower part of the smoke baffle to rotate forward and backward through the cooperation of the driving assembly, the linkage and the connecting rod, and the upper end of the movable rod is rotatably connected to the smoke baffle, and the rotatable connection with the smoke baffle is located above the connection between the driving mechanism and the smoke baffle, the lower end of the movable rod is coaxially arranged with the linkage and can rotate around the axis of the mounting shaft, that is, the upper part of the smoke baffle rotates relative to the casing together with the movable rod, because the lower end of the movable rod coincides with the rotation center of the linkage, and the rotation center, the connecting rod and the rotation connection of the smoke baffle are The rotation center of the connected rod and the rotation center of the rotation connection between the movable rod and the smoke damper are the three vertices of the triangle to ensure that the smoke damper is more stable after opening. When the air inlet needs to be opened, the driving mechanism drives the lower part of the smoke damper to rotate forward. At this time, the movable rod moves downward under the action of the gravity of the smoke damper, and the smoke damper will move downward until its top edge is not higher than the top surface of the box body and remains stable. In this way, the gap between the top of the casing and the cabinet can be reduced, and there is no need to leave a gap between the top of the casing and the wall cabinet, thereby avoiding cleaning in the gap.

[0040] The present invention is further described in detail below with reference to the accompanying drawings.

[0041] like Figures 1 to 7As shown, the side-suction range hood of this embodiment includes a housing 1, a smoke baffle 2, a connecting rod 31, a linkage, a driving assembly and a movable rod 4. Among them, the housing 1 has a chamber 10 inside. The front panel of the housing 1 gradually tilts backward from top to bottom, and the upper area of ​​the front panel has an air inlet 101 connected to the chamber 10, then the surface where the air inlet 101 is located gradually tilts backward from top to bottom. In addition, an inner panel 12 arranged side by side with the surface where the air inlet 101 is located is provided in the chamber 10, and a filter 121 is installed on the inner panel 12 at a position corresponding to the air inlet 101.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, the smoke baffle 2 is arranged at a position of the housing 1 corresponding to the air inlet 101, and can rotate forward relative to the housing 1 to open the air inlet 101 or rotate backward to close the air inlet 101 under the drive of the driving assembly. When the air inlet 101 is in a closed state, the top edge of the smoke baffle 2 is located below the top surface of the housing 1 or is flush with the top surface of the housing 1. In this embodiment, as shown in FIG. Figure 1 and Figure 2 As shown, the top edge of the smoke baffle 2 is flush with the top surface of the housing 1. In addition, upper mounting seats 21 and lower mounting seats 22 are arranged at intervals from top to bottom on both left and right sides of the back of the smoke baffle 2. Specifically, the upper mounting seats 21 and lower mounting seats 22 on the same side are formed on the bracket 20.

[0043] like Figure 6 As shown, a vertically arranged mounting plate 11 is arranged in the chamber 10, and the mounting plate 11 is arranged side by side with the left and right side wall panels of the housing 1, and the top of the mounting plate 11 is connected to the top wall of the chamber 10. The connecting rod 31 and the linkage member constitute a transmission mechanism, and there are two groups of transmission mechanisms, which are respectively arranged on the left and right sides of the smoke baffle 2 and are located behind the smoke baffle 2. Each group of transmission mechanisms corresponds to a mounting plate 11 and a movable rod 4. The above two groups of transmission mechanisms have the same structural form, and one of the transmission mechanisms is taken as an example for description below.

[0044] The movable rod 4, the linkage member and the mounting plate are arranged at intervals along the left-right direction, wherein the movable rod 4 is located between the linkage member and the mounting plate on the corresponding side. The mounting shaft 112 extending along the left-right direction is installed on the left and right mounting plates 11. The movable rod 4 is located behind the smoke baffle 2, and gradually tilts backward from top to bottom, and is a straight rod. The lower end of the aforementioned movable rod 4 is installed on the mounting shaft 112, and rotates around the rotation axis of the mounting shaft 112, and the rotation center of the lower end of the movable rod 4 and the mounting plate 11 is E. The upper end of the movable rod 4 is rotatably connected to the upper mounting seat 21 through a connecting shaft 113 extending left and right, and the rotation axis of the upper end of the movable rod 4 (i.e., the axis of the connecting shaft 113) extends along the left-right direction, and the connecting shaft 113 of the aforementioned movable rod 4 is located above the first end of the connecting rod 31, and the rotation center of the upper end of the movable rod 4 rotatably connected to the upper mounting seat 21 is B. The upper end of the movable rod 4 is rotatably connected to the upper mounting seat 21 on the back of the smoke damper 2, and the lower end of the movable rod 4 is rotatably connected to the mounting plate 11, that is, the smoke damper 2 can rotate along with the movable rod 4 around the axis of the mounting shaft 112, that is to say, the smoke damper 2 can move up and down. In this way, when the driving assembly drives the smoke damper 2 to rotate forward and open the air inlet 101, since the upper mounting seat 21 of the smoke damper 2 is rotatably connected to the upper end of the movable rod 4, the smoke damper 2 can rotate downward at this time, and the smoke damper 2 can move downward until its top edge is maintained below the top surface of the casing 1 or is flush with the top surface of the casing 1.

[0045] The linkage member in this embodiment is a polygonal rotating plate 34. The linkage members in each transmission mechanism are mounted on the mounting shaft 112, and the power output end of the drive assembly is drivingly connected to the power input end of the rotating plate 34 to drive the linkage member to rotate around the axis of the mounting shaft 112.

[0046] like Figure 2 and Figure 3As shown, the driving assembly is an electric push rod mechanism 33 located in the chamber 10, and the electric push rod mechanism 33 includes a push rod housing 331 and a push rod 332 that performs linear reciprocating motion relative to the push rod housing 331. The free end of the push rod 332 is rotatably connected to the linkage member, and the aforementioned rotating plate 34 is located between the push rod and the movable rod 4 along the left and right directions. The rotation center of the rotation connection between the push rod 332 and the rotating plate 34 is D, and one end of the push rod housing 331 away from the push rod 332 is rotatably connected to the housing 1. The connecting rod 31 is located behind the smoke baffle 2, and the first end of the connecting rod 31 is rotatably connected to the lower mounting seat 22 of the smoke baffle 2, then the first end of the connecting rod 31 is located below the upper end of the movable rod 4, and the second end of the connecting rod 31 is rotatably connected to the rotating plate 34, and the rotation center of the rotation connection is F, and the rotation centers D, E and F are the three vertices of the triangle, and are respectively located at the corresponding corners of the rotating plate 34. The rotation axis of the first end and the second end of the connecting rod 31 are extended in the left-right direction. In this way, under the drive of the electric push rod mechanism 33, the connecting rod 31 is driven to move forward and backward through the transmission of the linkage member to rotate the smoke shield 2 forward and backward. The rotation center of the upper end of the movable rod 4 and the upper mounting seat 21 is B, and the rotation center of the connecting rod 31 and the lower mounting seat 22 is A. The rotation center A, the rotation center B and the rotation center E are the three vertices of the triangle to ensure that the smoke shield is more stable after opening.

[0047] like Figure 6 As shown, the mounting plate 11 is provided with a limiting portion 111 capable of limiting the upper end of the movable rod 4 from rotating downward. Specifically, the limiting portion 111 is formed on the rear edge of the mounting plate 11 and protrudes toward the movable rod 4. The first portion 40 of the movable rod 4 located below the mounting shaft 112 is located below the limiting portion 111. When the air inlet 101 is in an open state, the first portion 40 abuts against the bottom edge of the limiting portion 111, thereby maintaining the height of the smoke shield 2 when it descends. When the air inlet 101 is in an open state, the smoke shield 2 has a first position and a second position. When the smoke shield 2 is in the first position, the lower end of the smoke shield 2 swings forward to reach the second position. The movable rod 4 and the rotating plate 34 are arranged in sequence along the left-right direction. In order to prevent the smoke shield 2 from shaking when the smoke shield 2 is in the second position, a first side edge 342 of the rotating plate 34 adjacent to the rotation center D and F is provided with a protrusion 341 extending toward the movable rod 4, and the protrusion 341 is located on the movable rod 4. When the smoke shield 2 is in the second position, the rotating plate 34 rotates to the position where its protrusion 341 is against the position of the movable rod 4 located on the mounting shaft 112; and the connecting rod 31 is arranged along the length direction of the connecting line AE.

[0048] like Figure 2As shown, the lower part of the movable rod 4 is provided with an extension portion 411 for limiting the rotation of the rotating plate 34 and thereby limiting the backward movement of the connecting rod 31. The extension portion 411 is formed on the bottom edge of the movable rod 4, and the extension portion 411 extends toward the rotating plate 34. When the air inlet 101 is in a closed state, the extension portion 411 is located under the rotating plate 34 and abuts against the second side edge 343 of the rotating plate 34 adjacent to the rotation center D and F.

[0049] The working process of the above-mentioned smoke baffle is as follows:

[0050] When the air inlet 101 needs to be opened, the electric push rod mechanism 33 works to drive the rotating plate 34 to rotate. Since the upper end of the movable rod 4 is rotatably connected to the upper mounting seat of the smoke baffle 2, and the lower end of the movable rod 4 is rotatably connected to the mounting plate 11 of the casing 1, the movable rod 4 slowly falls down under the gravity of the smoke baffle 2 (since the rotating plate 34 is still pressing the extension portion 411 of the movable rod 4 at this time, the upper end of the movable rod 4 slowly falls down), and the first part 40 of the movable rod 4 abuts against the limiting portion 111 on the mounting plate 11 and stops moving. At this time, the rotating plate 34 continues to push the connecting rod 31 to make the smoke baffle 2 continue to rotate forward. After reaching the second position, the air inlet 101 is in a fully open state; at this time, the protrusion 341 on the rotating plate 34 will press the movable rod 4, thereby fixing the movable rod 4.

[0051] When the air inlet 101 needs to be closed, the rotating plate 34 drives the connecting rod 31 to pull the smoke baffle 2 to rotate backward. Since the upper end of the movable rod 4 is rotationally connected to the upper mounting seat of the smoke baffle 2, and the lower end of the movable rod 4 is rotationally connected to the mounting plate 11 of the casing 1, the upper end of the movable rod 4 can slowly move backward. When it is close to the closed state, the rotating plate 34 will press on the extension part 411 on the movable rod 4, thereby completely tightening the smoke baffle 2 to close.
