TECHNICAL FIELD

[0003] The utility model relates to the technical field of range hood, specifically to oil fume separation and cleaning component and range hood. BACKGROUND

[0004] As the core component of the range hood, the oil fume separator is designed to separate oil fume during cooking. The design usually includes multiple layers of blocking structures to achieve separation effect by intercepting oil and gas mixture multiple times. The separated oil flows to the oil collection device along the blocking layer due to gravity. However, over time and with changes in cooking conditions, some oil will adhere to the blocking layer of the oil fume separator. At this time, the user needs to manually disassemble the oil fume separator for cleaning. There is a range hood in the prior art that discloses an automatic cleaning mechanism. The filter plate is easy to clean, and the cleaning mechanism is composed of a filter plate cover on one side of the machine body, an opposite side motor, a screw driven by the motor, a driving block on the screw, a support frame, a connecting frame and a scraping plate. The mechanism drives the scraping plate to move horizontally, removing oil and debris on the filter plate cover, allowing them to fall into the collection groove below. However, this left-right scraping cleaning method is only suitable for single-layer mesh covers and is not suitable for the oil fume separator with multiple layers of blocking structures mentioned in the present application. SUMMARY

[0005] The utility model aims to overcome the shortcomings of the prior art and develop an automatic cleaning system that can efficiently clean oil from oil fume separators with multiple blocking layers, solve the problem of oil adhesion and optimize user experience.

[0051] The technical scheme of the utility model is explained below in combination with the drawings and specific embodiments.

[0052] The present application generally relates to an oil fume separation cleaning device, a filter plate unit, a cleaning unit, a smoke collection part and a range hood. The "front side" and "rear side" of the present application generally refer to the side of the panel facing the direction of the airflow of the range hood as the front side, and the back as the rear side. Of course, the front and rear sides can be defined by the specific orientation in a certain component.

[0053] Referring to Figures 1 to 5 , Figures 16 to 23 , one embodiment of the oil fume separation cleaning device a of the present application includes two filter plate units 2, two cleaning units 3 and a driving mechanism 4; the two filter plate units 2 are arranged apart from each other, and each filter plate unit 2 includes a first filter plate 2.1 and a second filter plate 2.2; the two cleaning units 3 are respectively horizontally extended and movable to cooperate with the two filter plate units 2, and each cleaning unit 3 is at least provided with a front scraping part 301 coupled with the surface of each layer of filter plate on the air inlet side; the driving mechanism 4 includes a driver 4.1 and a rigid transmission member 4.2 connecting the two cleaning units 3 and the driver 4.1, and the driver 4.1 is at least partially installed between the two filter plate units 2; the driver 4.1 drives the two filter plate units 2 to scrape at least the surface of each layer of filter plate on the air inlet side to realize automatic cleaning of the oil fume separation device. In other embodiments, the filter plate unit 2 can include only one filter plate or three or more filter plates, and the number of layers can be selected according to the cleaning effect.

[0054] The oil fume separation and cleaning device a of the present application is provided with two filter plate units 2, each of which comprises one or more filter plates, and a driver 4.1 is at least partially mounted between the two filter plate units 2, which optimizes the space utilization and makes the overall structure more compact. The design of the two cleaning units 3 can effectively clean the surface of the filter plate. The design of the driving mechanism 4 enables the driver 4.1 to drive the two cleaning units 3 to work synchronously through the rigid transmission member 4.2, thereby achieving automatic scraping and cleaning of at least the air inlet side surface of each layer of filter plate. The modular design can facilitate the upgrading of the oil fume separation and cleaning device a and realize technical upgrading. The multi-layer design of the filter plate unit 2 can significantly enhance the oil fume separation effect, improve the filtering efficiency, and effectively block and filter particulate matter and oil in the oil fume. The cleaning unit 3 is equipped with a cleaning subunit (3.1, 3.2) corresponding to each layer of filter plate (2.1, 2.2), which can effectively ensure that the filter plate (2.1, 2.2) is fully cleaned.

[0055] Referring to Figures 1 to 4 , Figures 13 to 15 The driver 4.1 can include a motor 4.11 and a screw nut mechanism 4.12, the nut member 4.121 of the screw nut mechanism 4.12 is connected with the rigid transmission member 4.2, and the screw rod 4.122 of the screw nut mechanism 4.12 is mounted between the two filter plate units 2 along the length direction. Due to the arrangement of the two filter plate units 2 of the present application, a compartment is formed between them, and the arrangement and installation position of the driver 4.1 make the product structure compact and the driving connection more reliable. Specifically, in one embodiment, the nut member 4.121 is fixedly connected with a nut connecting seat 4.121', and the rigid transmission member 4.2 is fixedly connected with the nut connecting seat 4.121', such as through screws or other existing known connecting structures.

[0056] In order to facilitate installation, the rigid transmission member 4.2 can be provided with a movable channel. Specifically, the driving mechanism 4 is provided with a driving base 4.13, the motor 4.11 is mounted on the upper part of the driving base 4.13, the screw rod 4.122 of the screw nut mechanism 4.12 is mounted along the length direction of the driving base 4.13, the driving base 4.13 is at least partially mounted between the two filter plate units 2, and the two ends of the driving base 4.13 are provided with driving mounting portions 4.14. The use of the screw nut mechanism 4.12 for driving integrates the motor 4.11 and the screw nut mechanism 4.12 in the driving base 4.13, which provides a movable space for the rigid transmission member 4.2 to ensure smooth movement therebetween. This design not only simplifies the structure and improves the space utilization, but also ensures the accuracy and reliability of the transmission.

[0057] The transmission between the motor 4.11 and the screw rod 4.122 can be through a worm gear engagement, and of course, other coupling modes can also be used, such as the motor output shaft being fixedly connected with the screw rod 4.122. In addition, other known connection modes can also be used to achieve transmission coupling.

[0059] One embodiment of the rigid transmission member 4.2 is formed by sheet metal processing, such as by bending the two long sides to increase the structural strength. Of course, in other embodiments, the rigid transmission member 4.2 can also be processed by using other existing processes, such as die casting, extrusion molding, etc., and the material can be steel, aluminum alloy, etc.

[0060] Referring to Figures 10 to 13 , the middle part of the rigid transmission member 4.2 is in transmission coupling with the driver 4.1, and the two ends extend to the two sides of the filter plate support 1, and the rigid transmission member 4.2 is arranged at the rear side of the two filter plate units 2, and the rigid transmission member 4.2 is provided with a guide mechanism 4.3 on the two sides of the filter plate support 1, which can be connected as described above. The guide mechanism 4.3 can ensure stable transmission and realize efficient synchronous operation of the two cleaning units 3. Transmission coupling refers to the connection of the middle part of the rigid transmission member 4.2 with the output part of the driver 4.1, so that the driver 4.1 can drive the rigid transmission member 4.2 to move when the driver 4.1 works. For example, when the driver 4.1 adopts a motor and a screw nut mechanism, the rigid transmission member 4.2 is directly or indirectly connected with the nut of the screw nut mechanism; when the driver 4.1 adopts a linear motor or the like, the rigid transmission member 4.2 is connected with the conveying end.
