Description

Technical Field

[0001] This utility model relates to the field of fume exhaust pipes, specifically a novel airflow-type fume exhaust pipe for kitchens. Background Technology

[0002] An airflow-type fume extraction duct is a duct system used to exhaust kitchen fumes. It relies on the suction generated by a range hood or fan to create airflow within the duct, collecting the fumes at their source and transporting them outdoors. A common example is a centrifugal range hood, where a motor drives an impeller to rotate at high speed, causing the fumes to be thrown into the duct by centrifugal force and then discharged through the duct.

[0003] In existing technologies, flues are generally fully enclosed except for the inlet and outlet. Therefore, when determining whether a flue needs cleaning, one can only rely on personal experience, which is not accurate enough. Furthermore, during monitoring and inspection, it is also impossible to effectively determine whether the flue has been effectively cleaned. Utility Model Content

[0004] The purpose of this utility model is to provide a novel kitchen airflow-type fume exhaust pipe in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel kitchen airflow-type fume exhaust duct, comprising a flue spliced ​​by connecting flanges, with a sealing ring provided between the spliced ​​connecting flanges, an opening on one side plate of the flue, a viewing window fixedly installed on the inner wall of the opening, a pushing mechanism penetrating to the inner wall of the flue installed above the opening on the side plate of the flue, a fixing seat fixedly installed on the inner wall of the side plate of the flue, the fixing seat being connected to a baffle via a rotation reset mechanism, the baffle being used to cover the side of the viewing window located in the inner cavity of the flue, and outwardly protruding wing plates integrally formed on both sides of the baffle, the wing plates abutting against the output end of the pushing mechanism, and a receiving groove for accommodating the baffle and wing plates being provided on the inner wall of the flue.

[0006] As a further embodiment of this utility model: the pushing mechanism includes a guide rod fixedly connected to the flue side plate, the guide rod being located directly above the opening, a sliding plate being slidably connected to the outer wall of the guide rod, and a push rod penetrating into the flue cavity being fixedly installed on one side of both ends of the horizontal bar portion of the sliding plate.

[0007] As a further improvement of this utility model: a circular hole is provided on the side plate of the flue for the push rod to slide, and a sealing ring is installed on the inner wall of the circular hole.

[0008] As a further embodiment of this utility model: the rotational reset mechanism includes a rotating shaft rotatably connected to the inner side of the fixed seat, a rotating seat rotatably mounted on the outer circumference of the rotating shaft, the other end of the rotating seat being fixedly connected to the baffle, grooves being provided at both ends of the rotating seat, the end of the groove near the rotating seat being an open mechanism, a torsion spring being engaged between one end of the inner wall of the groove and the inner side of the rotating seat, and the torsion spring being sleeved on the outer circumference of the rotating shaft.

[0009] As a further improvement of this utility model, the inner side of the fixing seat and one end of the inner wall of the groove are both provided with a snap-fit ​​groove that matches the end of the torsion spring.

[0010] As a further improvement of this utility model, a counterweight is embedded in the lower back end of the baffle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 In this embodiment of the utility model, a novel kitchen airflow-type fume exhaust pipe includes a flue 1 spliced ​​by connecting flanges 2. A sealing ring is provided between the spliced ​​connecting flanges 2. An opening 3 is provided on one side plate of the flue 1. A viewing window 4 is fixedly installed on the inner wall of the opening 3. A pushing mechanism that penetrates to the inner wall of the flue 1 is installed above the opening 3 on the side plate of the flue 1. A fixing seat 8 is fixedly installed on the inner wall of the side plate of the flue 1. The fixing seat 8 is connected to a baffle 10 through a rotation reset mechanism. The baffle 10 is used to block the side of the viewing window 4 located in the inner cavity of the flue 1. The baffle 10 has outwardly protruding wing plates 12 integrally formed on both sides. The wing plates 12 abut against the output end of the pushing mechanism. A receiving groove is provided on the inner wall of the flue 1 to accommodate the baffle 10 and the wing plates 12.

[0021] In this embodiment: First, when checking the oil stains inside the flue 1, a pushing force is applied to the pushing mechanism, which slides along the outer wall of the guide rod 5. The pushing mechanism applies a pushing force to the wing plate 12, which then drives the baffle 10 to rotate and open. After the baffle 10 is opened to a suitable degree, a handheld flashlight is used, and the light-emitting end of the handheld flashlight is attached to the viewing window 4. The light shines through the viewing window 4 onto the inner wall of the flue 1, and the oil stains inside the flue 1 can be seen, indicating whether cleaning is needed. This can also be used for inspection after the flue 1 has been cleaned and reassembled.

[0022] During the process of the baffle 10 being rotated open, the rotation reset mechanism rotates, and at this time the torsion spring 14 in the rotation reset mechanism twists and has a reset force.

[0023] After inspection, the mechanism is reset by pulling, at which point the torsion spring 14 is reset, and the baffle 10 and the wing plate 12 are rotated and reset into the receiving groove.

[0024] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The pushing mechanism includes a guide rod 5 fixedly connected to the side plate of the flue 1. The guide rod 5 is located directly above the opening 3. A sliding plate 6 is slidably connected to the outer wall of the guide rod 5. A push rod 7 that penetrates into the inner cavity of the flue 1 is fixedly installed on one side of the crossbar of the sliding plate 6. A round hole for the push rod 7 to slide is opened on the side plate of the flue 1. A sealing ring is installed on the inner wall of the round hole.

[0025] In this embodiment: when a thrust is applied to the pushing mechanism, the thrust acts on the sliding plate 6, and the sliding plate 6 moves along the outer wall of the guide rod 5 toward the flue 1. The moving sliding plate 6 drives the push rod 7 to slide along the round hole.

[0026] After the inspection is completed, a pulling force is applied to the sliding plate 6, which then drives the push rod 7 to reset.

[0027] Please refer to this carefully. Figure 3 , Figure 4 and Figure 5 The rotation reset mechanism includes a rotating shaft 15 rotatably connected to the inner side of the fixed seat 8. A rotating seat 9 is rotatably mounted on the outer periphery of the rotating shaft 15. The other end of the rotating seat 9 is fixedly connected to the baffle 10. The two ends of the rotating seat 9 are provided with grooves 13. The end of the groove 13 near the rotating seat 9 is an open mechanism. A torsion spring 14 is engaged between the inner wall of the groove 13 and the inner side of the rotating seat 9. The torsion spring 14 is sleeved on the outer periphery of the rotating shaft 15.

[0028] In this embodiment: when the pushing mechanism is pushed, the push rod 7 applies a compressive force to the wing plate 12. The wing plate 12 is driven by the force to rotate the baffle 10 and the rotating seat 9 synchronously around the rotating shaft 15. At this time, the fixed seat 8 remains stationary. When the rotating seat 9 rotates, the end of the torsion spring 14 that is engaged with the rotating seat 9 moves accordingly, while the end of the torsion spring 14 that is engaged with the fixed seat 8 remains stationary. At this time, the torsion spring 14 is twisted and has a restoring force. When the pushing mechanism is reset, the torsion spring 14 drives the rotating seat 9 to reset, and the rotating seat 9 can drive the baffle 10 and the wing plate 12 to reset.

[0029] Please refer to this carefully. Figure 5 Both the inner side of the fixing seat 8 and one end of the inner wall of the groove 13 are provided with snap-fit ​​grooves that match the end of the torsion spring 14.

[0030] In this embodiment, the snap-fit ​​groove accommodates both ends of the torsion spring 14, so that the torsion spring 14 can be twisted as the rotating seat 9 rotates.

[0031] Please refer to this carefully. Figure 4 and Figure 5 A counterweight 11 is embedded in the lower back end of the baffle 10.

[0032] In this embodiment, the design of the counterweight 11 can help the baffle 10 to be reset better after rotation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
