Description

Technical Field

[0001] The utility model belongs to the field of oil fume filters, and in particular relates to an oil fume filter which can realize self-cleaning. Background Art

[0002] Potato chips are made by slicing potatoes and then frying them. The preparation process includes material selection, cleaning, peeling, trimming, slicing, rinsing, rinsing, drying, frying, seasoning, inspection, weighing and packaging.

[0003] The frying process of potatoes will inevitably produce a lot of oil smoke. Therefore, the use of range hoods is also a key component in the production line of potato chips and plays a vital role. During use, the range hood uses a fan to extract the oil smoke to the outside, and the airflow discharged from the range hood to the outside still contains a certain amount of oil smoke and water vapor, which seriously pollutes the outdoor environment.

[0004] Therefore, the fumes from the frying process need to be filtered before they can be discharged outdoors. Utility Model Content

[0006] Technical solution: The utility model can realize a self-cleaning oil fume filter, comprising a box body with an oil fume filtering device inside and an exhaust pipe located at the upper end of the box body, and spray pipes for flushing the oil fume filtering device are provided in the box body and at the upper and lower ends of the oil fume filtering device respectively.

[0007] Furthermore, a spray ball is provided on the spray pipe of the filter located at the upper end of the oil fume filtering device.

[0008] Furthermore, the filter is provided with an H-shaped spray pipe extending from the spray pipe at the lower end of the oil fume filter device, and nozzles are provided at the ends of the H-shaped spray pipe. Preferably, the spray pipe at the lower end of the oil fume filter device is connected to the box body through a T-shaped connecting plate.

[0009] Furthermore, the smoke exhaust pipe of the filter is provided with an oil return groove at the end of the box body, and the oil return groove is arranged between the box body and the smoke exhaust pipe through a connecting box.

[0010] Furthermore, an oil return pipe is connected to the oil return groove of the filter, and the other end of the oil return pipe penetrates the box body and extends into the box body.

[0011] Furthermore, the oil fume filtering device is slidably mounted on the box body via a slide plate disposed on the inner side of the box body.

[0012] Furthermore, the filter box body is rotatably provided with a box door for facilitating the removal and placement of the oil fume filtering device. The box door is provided with a plurality of connecting plates with connecting holes. The box door is connected to the box body in a locking manner via a connecting rod that passes through the connecting plates.

[0013] Furthermore, a box plate is extended from the filter box body corresponding to the box door, and the lock is arranged on the box plate.

[0014] Furthermore, the filter box is also provided with a fan for exhausting smoke.

[0015] Beneficial effect: Compared with the prior art, the utility model has the advantages that the oil fume filter can not only filter and discharge the oil fume generated during the frying process, but also can realize self-cleaning of the oil fume filtering device, thereby increasing the service life of the oil fume filter.

[0020] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the utility model can realize a self-cleaning oil fume filter, comprising a box body 2, and an exhaust pipe 3 arranged at the upper end of the box body 2. A fan for exhausting smoke is implemented in the box body 2, through which the oil fume is sucked into the box body 2 and discharged through the exhaust pipe 3.

[0022] Among them, the box body 3 is provided with a box door, such as Figure 2As shown, a supporting slide plate is provided on the side wall of the box body 2 for the box door, so that the oil fume filter device 1 can be slidably arranged in the box body 2 through the slide plate, and is stably supported by the box door. The box door is rotatably arranged on the box body 2, and a plurality of connecting plates 11 with connecting holes are provided on the box door. The box door and the box body 2 are fixedly connected by a connecting rod 12 passing through the connecting hole and locked with a lock 13 provided on the box body 2. Box plates 14 are extended on both sides of the box body 2 corresponding to the box door, and the lock 13 is provided on the box plate 14 to lock the rotatably arranged box door. Through the setting of the box door, the oil fume filter device 1 in the box body 2 can be conveniently taken and placed. The oil fume filtering device 1 used in the present invention can be any filter device that is commonly used on range hoods in the art and can achieve oil fume filtering, without specific limitation. For example, the oil fume filtering device mentioned in the application number 2017212411545, entitled "A replaceable cleaning device for range hoods", or other filter devices known in the art can be used.

[0023] like Figure 3 and Figure 4 As shown, a spray pipe 4 is provided on the housing 2 of the oil fume filter, corresponding to the upper and lower ends of the oil fume filter device 1, so as to achieve the effect of cleaning the upper and lower ends of the oil fume filter device 1. A spray ball 5 is provided on the end of the spray pipe 4 located at the upper end of the oil fume filter device 1, and an H-shaped spray pipe 6 is connected to the spray pipe 4 located at the lower end of the oil fume filter device 1. The four ends of the H-shaped spray pipe 6 are provided with nozzles to achieve large-area cleaning of the oil fume filter device 1. The water inlet end of the spray pipe 4 is connected to the water pipe through a valve. In order to further improve the stable connection of the spray pipe 4, the spray pipe 4 located at the lower end of the oil fume filter device 1 is fixedly connected to the housing 2 through a T-shaped connecting plate 7.

[0024] In addition to the above, the utility model is also provided with an oil return groove 8 between the box body 2 and the smoke exhaust pipe 3, and the oil return groove 8 is connected between the box body 2 and the smoke exhaust pipe 3 through a connecting box 9 that is arranged through the upper and lower parts, and the oil return groove 8 is connected with the bottom end of the smoke exhaust pipe 3.
