Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a smoke collection device and a kitchen appliance. Background Technology

[0002] Common kitchen appliances such as range hoods and integrated stoves have smoke extraction functions. Their smoke extraction principle is based on aerodynamics. The motor drives the impeller to rotate, which expels the air inside the volute and creates negative pressure. Atmospheric pressure then draws the air in the kitchen space, carrying the fumes, into the air inlet, and then exhausts the fumes outdoors through the duct and exhaust pipe.

[0003] Existing range hoods achieve their smoke-collecting function by installing a flip-up plate on the body. When the range hood is not in operation, the flip-up plate covers the air inlet of the body to maintain the complete appearance of the range hood. When the range hood is in operation, the flip-up plate is driven by a flip-up drive mechanism to flip and open the air inlet, allowing the fumes to enter the smoke collection chamber inside the body.

[0004] For ease of operation, the control panel of a range hood is usually mounted on a flip plate, and the wiring harness connecting the control panel needs to be connected to the main control board of the unit. Since the flip plate is a moving part, the wiring harness swings along with it when it opens and closes, making it prone to wear or breakage. Utility Model Content

[0056] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0057] See Figures 1 to 3 This utility model provides a kitchen appliance, which can be a range hood, integrated stove, or integrated range hood, or other household appliances with smoke extraction functions. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collection device, which includes a smoke collection hood 10 and a flip-up plate 20. The smoke collection hood 10 and the flip-up plate 20 are connected by a hinge assembly 30. A fan is provided inside the housing 100 or the smoke collection hood 10 to extract cooking fumes and discharge them through a smoke guide channel within the housing 100. Exemplarily, the housing 100 is located on top of the smoke collection hood 10.

[0058] The smoke hood 10 has an air inlet that communicates with the smoke collection chamber of the smoke hood 10. For example, the air inlet is located on the front side of the smoke hood 10 and extends downward at an angle from front to back.

[0059] The hinge assembly 30 includes a hinge seat 31 and a swing arm 32. The hinge seat 31 is fixedly mounted on the smoke hood 10, and one end of the swing arm 32 is rotatably connected to the hinge seat 31. The flip plate 20 is fixedly connected to the other end of the swing arm 32. The hinge assembly 30 is used to connect the smoke hood 10 and the flip plate 20. The hinge seat 31 is fixedly mounted on the smoke hood 10 to provide support. One end of the swing arm 32 is rotatably connected to the hinge seat 31, and the other end of the swing arm 32 is fixedly connected to the flip plate 20, allowing the flip plate 20 to rotate relative to the smoke hood 10.

[0060] For example, one end of the swing arm 32 is rotatably connected to the hinge seat 31 via a pin 33, which extends along the rotation axis 301, allowing the swing arm 32 to rotate about the rotation axis 301. The hinge seat 31 and the smoke hood 10 can be connected via fasteners. The hinge seat 31 has a receiving opening 311 to receive the swing arm 32.

[0061] For example, the swing arm 32 includes an arcuate segment 321 and a straight segment 322 connected to each other. The end of the arcuate segment 321 away from the straight segment 322 is rotatably connected to the hinge seat 31, and the end of the straight segment 322 away from the arcuate segment 321 is connected to the flip plate 20.

[0062] For example, the smoke collection device further includes a drive mechanism for driving the tilting plate 20 to move. For example, the drive mechanism includes a push rod and a push rod motor. One end of the push rod is hinged to the smoke collection hood 10, and the other end of the push rod is hinged to the tilting plate 20. The push rod motor is used to drive the push rod to extend or retract, so that the push rod can drive the tilting plate 20 to rotate about the rotation axis 301.

[0063] The smoke collection device also includes a wiring harness 40, one end of which is connected to a controller inside the smoke collection hood 10, and the other end of which is connected to a control board on the flip plate 20. A power cord is electrically connected to the controller. The flip plate 20 is equipped with control components, such as a control panel or control buttons, which are electrically connected to the control board.

[0064] See Figures 3 to 12 The smoke collection device also includes a wiring structure 50, which is detachably connected to the swing arm 32. This facilitates installation, disassembly, or replacement. For example, the wiring structure 50 is snap-fitted, fastened, or magnetically connected to the swing arm 32.

[0065] In this embodiment, the wiring structure 50 is engaged with the swing arm 32. One of the wiring structure 50 and the swing arm 32 has a first slot 323, and the other has a first buckle 51. The first buckle 51 can be engaged into the first slot 323, thereby securing the wiring structure 50 and the swing arm 32 together. For example, the wiring structure 50 includes multiple first buckles 51, and the swing arm 32 has multiple first slots 323. During installation, the first buckles 51 are aligned with the first slots 323, and the wiring structure 50 is pressed to engage the first buckles 51 into the first slots 323. The wiring structure 50 can be engaged with the swing arm 32 along the rotation axis 301, thus fixing the wiring structure 50 to the swing arm 32. The snap-fit ​​connection not only reduces the use of fasteners, but also the routing channel 52 formed by the routing structure 50 is a net space for routing, with no structural features or fasteners occupying the routing channel 52, ensuring a larger routing channel 52 and minimizing the routing structure 50.

[0066] Along the extending direction of the swing arm 32, multiple first slots 323 are spaced apart on opposite sides of the width direction of the swing arm 32 to ensure uniform force distribution on the swing arm 32. Along the extending direction of the wiring structure 50, multiple first buckles 51 are spaced apart on opposite sides of the width direction of the wiring structure 50 to ensure uniform force distribution on the wiring structure 50.

[0067] The wiring structure 50 forms or is connected to a wiring channel 52 for threading the wire harness 40. Exemplarily, the wiring structure 50 has a wiring channel 52. Exemplarily, the wiring structure 50 has a detachable wiring section with a wiring channel 52.

[0068] The wiring channel 52 has an inlet 521 and an outlet 522, with the outlet 522 located relative to the inlet 521 near the rotation axis 301 of the swing arm 32. Exemplarily, the inlet 521 and outlet 522 are located at opposite ends of the wiring structure 50. Exemplarily, the inlet 521 is located at one end of the wiring structure 50, and the outlet 522 is located on the side of the wiring structure 50 away from the swing arm 32, to prevent interference between the wire harness 40 and the hinge seat 31.

[0069] The cable routing structure 50 includes a mounting portion 53 disposed at the cable outlet 522. The mounting portion 53 has a mounting groove 54, which communicates with the cable routing channel 52 and is used to mount a second fixing member. The second fixing member is used to fix the wire harness 40. Exemplarily, the second fixing member is a cable tie 60. The cable tie 60 can fix the wire harness 40 at the cable outlet 522, thus fixing the wire harness 40 to the cable routing structure 50. The cable tie 60 is easy to install, simple and reliable to fix, and low in cost. The cable tie 60 shown in the attached figure is not fully secured; it is only for illustration. In actual use, the cable tie 60 is fully secured to the wire harness 40.

[0070] At least a portion of the wiring channel 52 extends along the swing arm 32. While maintaining a compact structure, the space of the swing arm 32 is fully utilized, ensuring stable positioning of the wire harness 40. Exemplarily, the wiring structure 50 includes an interconnected arc-shaped portion and a straight portion. An inlet 521 is provided at the end of the straight portion away from the arc-shaped portion, and an outlet 522 is provided on one side of the arc-shaped portion at the end away from the straight portion. The arc-shaped portion of the wiring structure 50 connects to the arc-shaped segment 321 of the swing arm 32, and the straight portion of the wiring structure 50 connects to the straight segment 322 of the swing arm 32. The outer contour of the wiring structure 50 is substantially consistent with the outer contour of the swing arm 32.

[0071] In this embodiment, the wiring structure 50 includes a base plate and side plates disposed on opposite sides of the base plate. The base plate and the side plates form a U-shaped wiring channel 52. A plurality of first latches 51 are disposed on the side of the side plate away from the base plate. The placement of the first latches 51 does not occupy the space of the wiring channel 52, thereby minimizing the layout of the wiring structure 50.

[0072] The smoke collection device also includes a cable protection structure 70, which forms or connects to a cable routing space 71 for threading the cable harness 40. The cable routing space 71 communicates with the cable routing channel 52. Specifically, the cable routing space 71 communicates with the cable inlet 521 of the cable routing channel 52. One end of the cable harness 40 is connected to the control board on the flip plate 20, and the other end of the cable harness 40 passes through the cable routing space 71 and enters the cable routing channel 52 of the cable routing structure 50 from the cable inlet 521. The cable protection structure 70 not only guides the cable harness 40 but also protects the cable harness 40 on the flip plate 20.

[0073] The cable protection structure 70 is detachably connected to the flip plate 20; and / or, the cable protection structure 70 is detachably connected to the wiring structure 50. This facilitates installation, disassembly, or replacement. Exemplarily, the cable protection structure 70 is fixed by snap-fit, fastener connection, or magnetic connection. In this embodiment, one end of the cable protection structure 70 is snap-fitted to the wiring structure 50, and the other end of the cable protection structure 70 is detachably connected to the flip plate 20 by fasteners.

[0074] Of the cable protection structure 70 and the wiring structure 50, one is provided with a second slot 55, and the other is provided with a second latch 72. The second latch 72 can be engaged into the second slot 55 to secure the cable protection structure 70 and the wiring structure 50. For example, one end of the cable protection structure 70 is provided with the second latch 72, and the wiring structure 50 includes the second slot 55. During installation, the second latch 72 is aligned with the second slot 55, and the second latch 72 is engaged into the second slot 55 by pressing the cable protection structure 70.

[0075] The other end of the cable protection structure 70 is detachably connected to the flip plate 20 via fasteners. The cable protection structure 70 has fastener holes 73, and the flip plate 20 has a mounting plate 21 with through holes. During installation, the fastener holes 73 are aligned with the through holes, and the fasteners pass through the through holes and are threaded into the fastener holes 73. This snap-fit ​​connection not only reduces the use of fasteners, but also ensures that the cable routing space 71 formed by the cable protection structure 70 is a net routing space, with no structural features or fasteners occupying the routing space 71, thus guaranteeing a large routing space 71 while minimizing the cable protection structure 70.

[0076] To ensure structural strength, the area where fastener holes 73 are made on the wire protection structure 70 is locally thickened so that the wire protection structure 70 will not break due to the fastener holes 73.

[0077] In this embodiment, the fastener can be a screw or a riveted component, etc.

[0078] The wiring space 71 includes interconnected wiring channels 711 and transition areas 712. The wiring channels 711 are connected to the inlet 521 of the wiring channel 52. The transition area 712 is an open area with the opening located on the side of the cable protection structure 70. The transition area 712 facilitates the storage of the wire harness connector and the wire harness 40.

[0079] A bottom shell 22 is provided on the flip plate 20, and the bottom shell 22 covers the inside of the flip plate 20. The wire harness 40 extends from one side of the bottom shell 22 and runs into the inlet 521 of the wiring structure 50. The wire protection structure 70 covers the flip plate 20, so that the wire harness 40 located on the outside of the bottom shell 22 is blocked.

[0080] See Figures 13 to 20 The wiring structure 50 has a first constraint position 501 for fixing the wire harness 40. A second constraint position 101 for fixing the wire harness 40 is determined on the smoke hood 10 based on the movement trajectory of the first constraint position 501, ensuring that the movement angle of the wire harness 40 is within a set range. When the swing arm 32 rotates, it drives the wiring structure 50 to rotate. The wire harness 40 at the first constraint position 501 rotates with the swing arm 32, while the wire harness 40 at the second constraint position 101 remains stationary. Because the second constraint position 101 is determined on the smoke hood 10 based on the movement trajectory of the first constraint position 501, ensuring that the movement angle of the wire harness 40 is within a set range, the swing range of the wire harness 40 is minimized, preventing twisting, wear, or breakage, and guaranteeing the lifespan and reliability of the wire harness 40. The specific value of the set range can be set according to actual needs, as long as the swing range of the wire harness 40 is minimized.

[0081] As described above, the wiring channel 52 has an inlet 521 and an outlet 522, with the outlet 522 located near the rotation axis 301 of the swing arm 32 relative to the inlet 521. A second fixing member for securing the wire harness 40 is provided at the outlet 522 of the wiring structure 50. Exemplarily, the second fixing member is a cable tie 60, which secures the wire harness 40 at the outlet 522. Exemplarily, the second fixing member is a pressure plate, which is used to press the wire harness 40 and is detachably connected to the wiring structure 50. Therefore, in this embodiment, the first constraint position 501 is located at the outlet 522.

[0082] The swing arm 32 rotates around the rotation axis 301 between the closed and open positions, thus its movement trajectory is an arc. Since the wiring structure 50 is fixedly mounted on the swing arm 32, and the first constraint position 501 fixes the wire harness 40, its trajectory is also an arc. Exemplarily, the movement trajectory of the first constraint position 501 forms a first arc 201 on the first plane 202. The rotation axis 301 is perpendicular to the first plane 202 and intersects it at a rotation point 203. The first arc 201 and the rotation point 203 enclose a fan-shaped area. The projection of the second constraint position 101 onto the first plane 202 lies within the fan-shaped area enclosed by the first arc 201 and the rotation point 203.

[0083] For example, at the first constraint position 501, the wire harness 40 is secured by a cable tie 60; after determining the second constraint position 101 on the smoke hood 10 according to the movement trajectory of the first constraint position 501, the wire harness 40 is secured at the second constraint position 101 by the cable tie 60. Therefore, a suspended segment 41 is formed in the wire harness 40 between the first constraint position 501 and the second constraint position 101. In some embodiments, the length of the suspended segment 41 is equal to the distance between the first constraint position 501 and the second constraint position 101. In some embodiments, the length of the suspended segment 41 is greater than the distance between the first constraint position 501 and the second constraint position 101 to prevent the wire harness 40 from being pulled. The distance between the first constraint position 501 and the second constraint position 101 is L1, the length of the suspended segment 41 is L2, and the slack ratio E is defined as L2 / L1. Optionally, E is greater than 1 and less than or equal to 2. The rotation angle of the swing arm 32 is positively correlated with E; the larger the rotation angle of the swing arm 32, the larger the value of E, to ensure that the wire harness 40 is not pulled and to extend its service life.

[0084] The second constraint position 101 is located on one side of the first plane 202. The distance between the second constraint position 101 and the first plane 202 should not be too large or too small. If the distance between the second constraint position 101 and the first plane 202 is too large, it will occupy a large space. If the distance between the second constraint position 101 and the first plane 202 is too small, it will cause the wire harness 40 to be easily bent.

[0085] When the swing arm 32 is in the closed position, the first constraint position 501 is located at the first point 204. When the swing arm 32 is in the open position, the first constraint position 501 is located at the second point 205. A first straight line is formed between the first point 204 and the second point 205. The midpoint of the first straight line is taken as the reference point 206. The projection of the second constraint position 101 on the first plane 202 lies within a circular area centered on the reference point 206 and with a set radius r. The set radius r can be set according to actual needs. The reason for setting a circular area centered on the reference point 206 and with radius r is to ensure that the swing range of the harness 40 is small within the error range.

[0086] For example, the projection of the second constraint position 101 on the first plane 202 coincides with the reference point 206. When the swing arm 32 rotates around the rotation axis 301 between the closed position and the open position, the first constraint position 501 moves between the first point 204 and the second point 205. By setting the projection of the second constraint position 101 on the first plane 202 to coincide with the reference point 206, the amplitude of the up-and-down swing of the suspended segment 41 of the wire harness 40 is made basically symmetrical, further reducing the pulling on the wire harness 40, avoiding wear or breakage of the wire harness 40, and ensuring the life and reliability of the wire harness 40.

[0087] After determining the second constraint position 101 on the smoke hood 10, the cable tie 60 can be installed on the smoke hood 10 to secure the wire harness 40. The smoke hood 10 includes an outer shell and components such as a reinforcing plate and an oil receiving plate disposed within the outer shell.

[0088] The second constraint position 101, determined by the motion trajectory of the first constraint position 501, may be located on the outer shell, on the reinforcing plate, on the oil receiving plate or other plates, or even at a certain location in space.

[0089] The smoke hood 10 is provided with a first fixing member for fixing the wire harness 40. The position of the first fixing member can be selected according to actual needs. Preferably, the first fixing member is located at the second constraint position 101. Through the cooperation of the first fixing member and the wiring structure 50, the wire harness 40 is positioned and guided, so that the range of motion of the wire harness 40 is small, and the wire harness 40 is prevented from swinging significantly with the flip plate 20.

[0090] In this embodiment, a positioning groove 11 is provided on the smoke hood 10. The positioning groove 11 has a notch 112 facing the swing arm 32, and the second constraint position 101 is located at the bottom of the positioning groove 11. By providing the positioning groove 11, the wire harness 40 is positioned and guided, so as to guide the wire harness 40 to extend smoothly between the first constraint position 501 and the second constraint position 101.

[0091] A first fixing member is disposed at the bottom of the positioning groove 11. Exemplarily, the first fixing member is a cable tie 60. The bottom of the positioning groove 11 is provided with a mounting protrusion 12, and the mounting protrusion 12 is provided with a mounting hole 121 for mounting the cable tie 60. Exemplarily, the first fixing member is a wire clamping plate, which is used to clamp the wire harness 40 and is detachably connected to the smoke hood 10.

[0092] A clearance space 13 is provided on the smoke hood 10, and the swing arm 32 is located within the clearance space 13 to prevent interference between the swing arm 32 and the smoke hood 10. The notch 112 of the positioning groove 11 faces the clearance space 13. A flange 14 is provided at the edge of the notch 112 of the positioning groove 11. The flange 14 is folded towards the side away from the wire harness 40 to prevent the sharp edge from causing wear to the wire harness 40.

[0093] The sidewall of the positioning groove 11 is inclined to form a guide slope 111. The guide slope 111 guides the wire harness 40 from one side of the positioning groove 11 to the second constraint position 101, that is, to the second fixing member, so as to fix the wire harness 40. By setting the guide slope 111, the wire harness 40 can extend smoothly into the positioning groove 11 to prevent the wire harness 40 from bending.

[0094] The smoke-collecting assembly provided in this embodiment determines a first point 204 and a second point 205 based on the movement trajectory of the first constraint position 501, specifically an arc-shaped trajectory. A first straight line is formed by connecting the first point 204 and the second point 205. The midpoint of the first straight line is taken as a reference point 206. A straight line perpendicular to the first plane 202 is drawn from the reference point 206 and denoted as the second straight line. An appropriate position is selected on the second straight line as the second constraint position 101. The distance between the second constraint position 101 and the reference point 206 is set according to the actual situation.
