Side-suction range hood

Abstract

When the side-suction range hood is not needed for extracting smoke, the oil fume deflector is flipped over and stored between the closed smoke collecting plate and the smoke collecting hood; when extracting smoke is needed, the smoke collecting plate is switched from the closed state to the open state, so that the oil fume deflector is flipped over to the bottom of the smoke inlet to form an oil fume blocking state. The oil fume deflector is located below the smoke inlet and can block smoke rising from the bottom. The oil fume deflector can move the negative pressure area of the smoke collecting hood from the original smoke inlet position forward to the circumferential outer side of the oil fume deflector, especially to the left and right sides of the oil fume deflector, so that the negative pressure area is better adapted to the double burner position on the stove, so that most of the oil fume directly enters the negative pressure areas on the left and right sides of the oil fume deflector after rising, thereby avoiding the smoke leakage phenomenon caused by the excessively long oil fume path and improving the extraction effect.

Description

Technical Field

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

[0002] The smoke inlet of the existing side-suction range hood is mostly on the side of the smoke collecting hood and located in the middle of the side. The smoke collecting hood is provided with a smoke collecting plate structure. When the smoke collecting plate structure is flipped upward, the smoke inlet can be opened to increase the smoke collecting range.

[0003] Since oil smoke rises upward during cooking, the oil smoke path of the side-suction range hood has to turn (i.e. it first moves upward and then flows backward into the smoke inlet). This is because when the stove is cooking with fire, the exhaust gas after combustion will be mixed in the oil smoke, the temperature is very high, and the rising speed is very fast. The rapidly rising oil smoke is difficult to be captured by the side air inlet, causing the oil smoke to escape. Summary of the Invention

DETAILED DESCRIPTION

[0058] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0059] Example 1

[0060] like Figures 1-10As shown, the side-suction range hood provided by the embodiment of the present invention includes: a smoke collecting hood body 1, a smoke collecting plate 2 and a smoke deflector 3. A smoke inlet is provided on the front of the smoke collecting hood body 1. The smoke collecting plate 2 is rotatably connected or slidably connected to the smoke collecting hood body 1, so that the smoke collecting plate 2 can switch between a closed state and an open state. When the smoke collecting plate 2 is in the closed state, the smoke inlet is blocked. When the smoke collecting plate 2 is in the open state, the smoke inlet is exposed. In this embodiment, the smoke collecting plate 2 is rotatably connected to the smoke collecting hood body 1. The smoke collecting plate 2 can be rotated to be parallel to the front of the smoke collecting hood body 1 and cover the front of the smoke collecting hood body 1 to block the smoke inlet. At this time, the smoke collecting plate 2 is in a closed state, and the range hood does not extract smoke. The smoke collecting plate 2 is connected above the smoke inlet of the smoke collecting hood body 1. The smoke collecting plate 2 can be flipped forward relative to the smoke collecting hood body 1. The angle between the smoke collecting plate 2 and the front of the smoke collecting hood body 1 gradually increases and eventually reaches an open state. The smoke collecting plate 2 can prevent oil smoke from escaping to the front side.

[0061] like Figure 1 and Figure 2 As shown, in this embodiment, the oil fume deflector 3 is rotatably connected to the smoke collecting hood body 1 and the smoke collecting plate 2 respectively. The oil fume deflector 3 can be rotated to between the smoke collecting hood body 1 and the smoke collecting plate 2 and be in a stored state when the smoke collecting plate 2 is in a closed state. In the stored state, the oil fume deflector 3 can be parallel to the smoke collecting plate 2. The oil fume deflector 3 is stored between the smoke collecting hood body 1 and the smoke collecting plate 2. The oil fume deflector 3 is not exposed and is more beautiful. When it is necessary to smoke, the smoke collecting plate 2 can be flipped upward to the open state, and then the oil smoke deflector 3 can be flipped to the bottom of the smoke inlet to block the oil smoke. The oil smoke deflector 3 is located below the smoke inlet. In the left and right directions, the length of the oil smoke deflector 3 is roughly equal to the length of the smoke inlet, and the length of the oil smoke deflector 3 is smaller than the length of the smoke collecting plate 2. The oil smoke deflector 3 can block the smoke rising from the bottom. The oil smoke deflector 3 can make the negative pressure area of the smoke collecting hood 1 move forward from the original smoke inlet position to the circumferential outside of the oil smoke deflector 3, especially on the left and right sides of the oil smoke deflector 3, so that the negative pressure area is better adapted to the double burner position on the stove, so that most of the oil smoke rises and directly enters the negative pressure areas on the left and right sides of the oil smoke deflector 3. The negative pressure area is as follows Figure 1 The positions indicated by the two arrows in the middle can avoid the smoke leakage caused by the long oil smoke path and improve the smoke extraction effect.

[0062] like Figure 3 and Figure 4As shown, the oil fume deflector 3 includes a first side and a second side that are opposite to each other, a rotating shaft structure 31 is provided at the first side, and a first hinge structure is provided at the second side; the side-suction range hood includes a sliding connection groove 11 and a second hinge structure, one of the sliding connection groove 11 and the second hinge structure is provided on the smoke collecting hood body 1, and the other is provided on the smoke collecting plate 2; the first hinge structure is hinged to the second hinge structure; the rotating shaft structure 31 is slidably connected in the sliding connection groove 11, and the rotating shaft structure 31 can rotate in the sliding connection groove 11, so that the oil fume deflector 3 can switch between the oil fume blocking state and the storage state under the drive of the smoke collecting plate 2.

[0063] Because the oil fume deflector 3 is connected to the smoke collecting hood body 1 and the smoke collecting plate 2 respectively, when the smoke collecting plate 2 is switched from a closed state to an open state by rotating, the oil fume deflector 3 can be pulled forward to rotate the oil fume deflector 3 from the storage state to the oil fume blocking state. Conversely, when the smoke collecting plate 2 is rotated from an open state to a closed state, the smoke collecting plate 2 can push the oil fume deflector 3 backward and rotate it from the oil fume blocking state to the storage state. Through a reasonable linkage structure, the smoke collecting plate 2 drives the oil fume deflector 3 to move, which can avoid setting a driving mechanism for the oil fume deflector 3 separately.

[0064] like Figure 5 and Figure 6 As shown, specifically, in one implementation of this embodiment, the second hinge structure is provided on the smoke collecting plate 2, and the sliding connection groove 11 is provided on the smoke collecting hood body 1, and the sliding connection groove 11 is located below the smoke inlet. The number of sliding connection grooves 11 can be two, and the two sliding connection grooves 11 are spaced apart, and the two ends of the rotating shaft structure 31 on the first side are respectively slidably connected to the two sliding connection grooves 11.

[0065] The second side of the oil fume deflector 3 is hinged to the smoke collecting plate 2 through a first hinge structure and a second hinge structure, and the first side of the oil fume deflector 3 is provided with a rotating shaft structure 31. The length of the rotating shaft structure 31 is slightly larger than the length of the first side in the left and right directions. The two ends of the rotating shaft structure 31 are slidably connected between the two sliding connecting grooves 11, and the cross-section of the rotating shaft structure 31 can be circular. The rotating shaft structure 31 can rotate relative to the sliding connecting groove 11. The sliding connecting groove 11 can be located inside the smoke collecting hood body 1. The sliding connecting groove 11 is located on the lower side of the smoke inlet, and the extension direction of the sliding connecting groove 11 can be parallel to the front of the smoke collecting hood body 1. When the smoke collecting plate 2 switches from a closed state to an open state, the rotating shaft structure 31 slides upward along the sliding connection groove 11, and while sliding, the first hinge structure and the second hinge structure rotate relative to each other, so that the oil smoke deflector 3 that is parallel to the front of the smoke collecting hood body 1 flips forward to an oil smoke blocking state; conversely, when the smoke collecting plate 2 switches from an open state to a closed state, the rotating shaft structure 31 slides downward along the sliding connection groove 11, and the oil smoke deflector 3 can rotate and slide into the interior of the smoke collecting hood body 1.

[0066] like Figure 3 As shown, the sliding connection groove 11 can be located below the smoke inlet. When the oil fume deflector 3 is in the storage state, the first side is lower than the second side, and when the oil fume deflector 3 switches from the storage state to the oil fume blocking state, the angle a between the back of the oil fume deflector 3 and the front of the smoke hood body 1 can be in the range of 0-90° (excluding 90°), thereby preventing the oil fume deflector 3 from getting stuck. The two sliding connection grooves 11 can also be located on the left and right sides of the smoke inlet. When the oil fume deflector 3 is in the storage state, the first side is higher than the second side, and when the oil fume deflector 3 switches from the storage state to the oil fume blocking state, the angle a between the front of the oil fume deflector 3 and the front of the smoke hood body 1 can be in the range of 0-90° (excluding 90°), thereby preventing the oil fume deflector 3 from getting stuck and unable to rotate normally.

[0067] In another implementation of this embodiment, the second hinge structure can be provided on the smoke collecting hood body 1, and the sliding connection groove 11 is provided on the smoke collecting plate 2. The first hinge structure on the oil fume deflector 3 is hinged to the second hinge structure of the smoke collecting hood body 1, and the oil fume deflector 3 and the smoke collecting hood body 1 only rotate relative to each other, while the rotating shaft structure 31 on the oil fume deflector 3 is slidably connected to the sliding connection groove 11 on the smoke collecting plate 2, and the oil fume deflector 3 and the smoke collecting plate 2 both rotate and slide. The oil fume deflector 3 in the storage state can be stored in the two openings on the smoke collecting plate 2 that are oppositely arranged. Similarly, in this embodiment, when the oil fume deflector 3 is in the oil fume blocking state, the angle between it and the smoke collecting plate 2 is not 90°, so as to avoid the oil fume deflector 3 from getting stuck and unable to rotate normally.

[0068] The side-suction range hood is provided with a second driving mechanism 6, which is connected to the smoke collecting plate 2 and is used to drive the smoke collecting plate 2 to rotate so that the smoke collecting plate 2 can be switched between an open state and a closed state, thereby making the range hood more intelligent and avoiding manual opening of the smoke collecting plate 2 and contamination of the user's hands.

[0069] like Figure 3 As shown, specifically, the second driving mechanism 6 includes a connecting rod 21 and a second push rod motor, the second push rod motor is arranged on the smoke collecting hood body 1, the connecting rod 21 includes a first end and a second end, the position between the first end and the second end of the connecting rod 21 is hinged to the smoke collecting hood body 1, the first end of the connecting rod 21 is connected to the smoke collecting plate 2, and the second end is hinged to the driving end of the second push rod motor, and the second push rod motor swings by driving the connecting rod 21 to swing the smoke collecting plate 2 to an open state or a closed state.

[0070] like Figure 7 、 Figure 17 and Figure 25 As shown, side baffles 4 are provided on the left and right sides of the smoke collecting plate 2. The side baffles 4 can be perpendicular to the smoke collecting plate 2. A gap is provided between the edge of the oil smoke deflector 3 and the side baffles 4 along the left-right direction. The side baffles 4 are used to increase the pressure in the negative pressure areas on the left and right sides of the oil smoke deflector 3. The front of the smoke collecting hood 1 has a clearance hole to prevent the side baffles 4 from rotating. When the smoke collecting plate 2 is in the closed state, the side baffles 4 are stored inside the smoke collecting hood 1.

[0071] The oil fume deflector 3 has through holes 32 running through both sides thereof, and a negative pressure area is formed on the back side of the oil fume deflector 3. Part of the smoke can be sucked into the back side of the oil fume deflector 3 through the air vents and then directly absorbed by the smoke inlet.

[0072] like Figure 8 and Figure 18 Specifically, when the fume deflector 3 is in the fume blocking state, one of the through holes 32 may be located near one of the two edges spaced apart on the fume deflector 3 and close to the smoke collecting plate 2 along the front-to-back direction, thereby absorbing fume escaping forward. Another of the through holes 32 may be located near one of the two edges spaced apart on the fume deflector 3 and close to the smoke collecting hood 1, thereby absorbing fume escaping backward.

[0073] like Figure 9 As shown, there may be a through hole 32 located in the middle of two edges spaced apart on the oil smoke deflector 3, which can absorb the smoke flowing from bottom to top.

[0074] like Figure 10As shown, the oil fume deflector 3 can be a flat structure, or it can have a concave structure 33 that is concave from one side to the other side. When the oil fume deflector 3 has a concave structure 33, the overall anti-bending ability of the oil fume deflector 3 is improved and it is not easy to deform.

[0075] like Figure 22 As shown, a sinking platform 12 is provided at the edge of the smoke inlet, which is sunken toward the inner side of the smoke collecting hood body 1. When the oil fume deflector 3 is in the storage state, the sinking platform 12 toward the inner and lower side can provide storage space for the oil fume deflector 3, so that after the smoke collecting plate 2 is flush with the front of the smoke collecting hood body 1, the oil fume deflector 3 can be stored between the sinking platform 12 and the smoke collecting plate 2.

[0076] Example 2

[0077] like Figures 11-18 As shown, based on the embodiment 1, the structure of the oil smoke deflector 3 in this embodiment is different from the structure of the oil smoke deflector 3 in the embodiment 1. In this embodiment, as Figure 11 As shown, the oil fume deflector 3 includes at least two oil fume baffles connected in sequence along the first side toward the second side, and the two adjacent oil fume baffles are hinged, the first side is located on the oil fume baffle at the head end, and the second side is located on the oil fume baffle at the end, and at least two of the oil fume baffles can be unfolded when the oil fume deflector 3 is in the oil fume blocking state, and folded when the oil fume deflector 3 is in the storage state.

[0078] like Figure 13-16As shown, the oil fume deflector 3 in this embodiment is formed by hingedly connecting a plurality of oil fume baffles, and can be folded together in the storage state, thereby reducing the space occupied during storage. For example, the sliding connection groove 11 can be located on the smoke collecting hood body 1, the second hinge structure is located on the smoke collecting plate 2, and the oil smoke deflector 3 is formed by two oil smoke baffles hingedly connected, namely the inner oil smoke baffle 34 and the outer oil smoke baffle 35, the first side is located on the inner oil smoke baffle 34, the rotating shaft structure 31 is slidably connected in the sliding connection groove 11, and the second side is located on the outer oil smoke baffle 35, and in order to avoid the inner oil smoke baffle 34 and the outer oil smoke baffle 35 from getting stuck during the folding process, the rotation angle of the inner oil smoke baffle 34 and the outer oil smoke baffle 35 is less than 180°, and the rotation angle between the inner oil smoke baffle 34 and the front of the smoke collecting hood body 1 is less than 90°, that is, when the oil smoke deflector 3 is in the oil smoke blocking state, the angle b formed by the inner oil smoke baffle 34 and the outer oil smoke baffle 35 is less than 180°, and the angle c between the inner oil smoke baffle 34 and the front of the smoke collecting hood body 1 is less than 90°. When the oil fume deflector 3 switches from the oil fume blocking state to the storage state, the smoke collecting plate 2 flips backward, pushing the outer oil fume baffle 35, and the inner oil fume baffle 34 and the outer oil fume baffle 35 hinge position move upward, so that the angle between the outer oil fume baffle 35 and the inner oil fume baffle 34 gradually decreases, and the rotating shaft structure 31 at the first side edge of the inner oil fume baffle 34 slides upward, and the front of the outer oil fume baffle 35 and the front of the inner oil fume baffle 34 gradually merge, finally causing the oil fume deflector 3 to fold and move to the storage state.

[0079] The number of the oil smoke baffles can also be three, four or even more.

[0080] Example 3

[0081] like Figures 19-25 As shown, the difference from Example 1 is that, in this embodiment, the oil fume deflector 3 can be connected only to the smoke collecting hood body 1, or only to the smoke collecting plate 2, and the rotation of the smoke collecting plate 2 relative to the smoke collecting hood body 1 will not affect the rotation of the oil fume deflector 3.

[0082] Specifically, the side-suction range hood includes a first driving mechanism, the oil fume deflector 3 is connected to the first driving mechanism, and the first driving mechanism is used to drive the oil fume deflector 3 to switch between the oil fume blocking state and the storage state.

[0083] like Figure 21-24 As shown, for example, the oil fume deflector 3 can be hinged to the fume hood body 1, and a first drive mechanism can be connected to the fume hood body 1. The first drive mechanism drives the oil fume deflector 3 to rotate relative to the fume hood body 1, so that the oil fume deflector 3 is in the oil fume blocking state or the retracted state. When the oil fume deflector 3 is in the oil fume blocking state, a gap exists between the oil fume deflector 3 and the smoke collecting plate 2, and thus, negative pressure areas exist on the left, right, and front sides of the oil fume deflector 3.

[0084] Specifically, in one practicable embodiment, the first driving mechanism may include a first push-pull module, which may include a first push-rod motor 15. The first push-rod motor 15 pushes and pulls the oil fume deflector 3 to rotate the oil fume deflector 3. Specifically, a fixing base 14 may be provided on the smoke hood body 1, and a hinge shaft 36 on the oil fume deflector is rotatably connected to the fixing base 14. The smoke hood body 1 may also be provided with a push rod bracket 13. One end of the first push rod motor 15 is hinged to the push rod bracket 13, and the other end is hinged to the oil fume deflector.

[0085] In other embodiments, the first push-pull module may include a motor, and the hinge shaft 36 between the oil fume deflector 3 and the smoke collecting hood body 1 is connected to the motor, and the motor is used to drive the hinge shaft 36 to rotate, thereby realizing the flipping movement of the oil fume deflector 3.

[0086] Of course, the oil fume deflector 3 can also be hinged on the smoke collecting plate 2, and the first driving mechanism is also fixed on the smoke collecting plate 2 and drives the oil fume deflector 3 to flip.

[0087] Example 4

[0088] like Figures 26-30 As shown, the difference from embodiment 1 is that, in this embodiment, the oil fume deflector 3 can be connected only to the smoke collecting hood body 1, or only to the smoke collecting plate 2.

[0089] Specifically, the oil fume deflector 3 can be hinged to the smoke collecting plate 2. The side-suction range hood includes an elastic member, one end of which is connected to the oil fume deflector 3 and the other end is connected to the smoke collecting plate 2. The elastic member can cause the oil fume deflector 3 to have a tendency to rotate backward. When the smoke collecting plate 2 switches from a closed state to an open state, the distance between the smoke collecting plate 2 and the smoke collecting hood body 1 increases, and the elastic member is used to drive the oil fume deflector 3 to rotate backward to the oil fume blocking state. The smoke collecting hood body 1 is provided with a stop structure. When the smoke collecting plate 2 is switched from an open state to a closed state, the oil smoke deflector 3 abuts against the stop structure and prevents the oil smoke deflector 3 from moving backward relative to the smoke collecting hood body 1. The angle between the oil smoke deflector 3 and the smoke collecting plate 2 gradually decreases. When the smoke collecting plate 2 is fully rotated to the closed state, the oil smoke deflector 3 is in a retracted state. The oil smoke deflector 3 is flipped by the opening and closing of the smoke collecting plate 2 driven by the elastic member, avoiding the need to set an additional driving mechanism for the oil smoke deflector 3, making the overall structure simpler.

[0090] like Figure 27 and Figure 28As shown, in another embodiment of this embodiment, the oil fume deflector 3 is hinged to the smoke hood body 1, and the side-suction range hood includes an elastic member, one end of which is connected to the oil fume deflector 3 and the other end is connected to the smoke hood body 1. The elastic member can cause the oil fume deflector 3 to have a tendency to rotate forward. When the smoke collecting plate 2 switches from a closed state to an open state, the distance between the smoke collecting plate 2 and the smoke collecting hood body 1 increases, and the elastic member is used to drive the oil fume deflector 3 to rotate forward to an oil fume blocking state; when the smoke collecting plate 2 switches from an open state to a closed state, the smoke collecting plate 2 can push the oil fume deflector 3 toward the direction of the smoke collecting hood body 1 to a retracted state. When the oil fume deflector 3 is in the oil fume blocking state, a gap exists between the oil fume deflector 3 and the smoke collecting plate 2, and then, negative pressure areas exist on the left, right, and front sides of the oil fume deflector 3.

[0091] like Figure 30 As shown, the elastic member can be a tension spring, a compression spring or a torsion spring 5. In this embodiment, a torsion spring 5 is used, and the torsion spring 5 is arranged at the hinge shaft 36 of the oil smoke deflector 3.

[0092] Furthermore, in order to make the angle formed between the oil fume deflector 3 and the front of the smoke collecting hood body 1 in the oil fume blocking state to be a preset angle value, a limiting structure can be provided on the smoke collecting hood body 1 or the baffle, and when the baffle rotates to abut against the limiting structure, it no longer rotates. In this embodiment, the bottom edge of the oil fume deflector 3 is hinged to the inner side of the smoke inlet of the smoke collecting hood body 1, and the elastic member can drive the oil fume deflector 3 to rotate toward the outer side of the smoke inlet, and the lower edge of the smoke inlet forms the above-mentioned limiting structure. At the same time, it should be noted that when the oil fume deflector 3 is in the oil fume blocking state, the angle e between the front of the oil fume deflector 3 and the back of the smoke collecting plate 2 is not equal to 90°, so as to avoid the smoke collecting plate 2 and the oil fume deflector 3 being stuck vertically, and the smoke collecting plate 2 being unable to drive the oil fume deflector 3 to flip.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
