Description

Technical Field

[0001] The utility model belongs to the technical field of oil fume purification, and more specifically, particularly relates to a rolling curtain type water retaining structure for a self-cleaning oil fume purifier and the oil fume purifier. Background Art

[0002] In a building, kitchen exhaust enters a public flue. The oil smoke in the public flue contains a large amount of oily particles. If these oily particles are directly discharged into the atmosphere without being treated, they will cause serious pollution to the atmosphere. In the prior art, there are also technical solutions to solve the corresponding problems. For example, the Chinese invention patent with publication number CN113465001A sets an oil fume purification device outside the public flue. The liquid oil generated after decomposition by the electrostatic adsorption device first settles into the guide groove under the action of gravity, and then flows into the oil collection box through the guide groove for collection, while the clean air is discharged through the flue outlet (10). At the same time, in order to ensure the improvement of the oil fume purification efficiency and avoid short circuit and fire of the equipment, a cleaning nozzle is arranged in the oil fume purification box to realize the self-cleaning function of the equipment.

[0003] When the equipment is self-cleaning, spray liquid will be generated. In order to prevent the spray liquid from entering the flue, the prior art uses a plurality of oil guide grooves arranged in the same direction in an alternating manner in multiple layers in the installation cavity of the oil guide device. However, after analysis, it is found that the oil guide grooves will block the flue gas and affect the flow of flue gas during normal fume purification. In order to solve this problem, a structure is needed to block the spray liquid from entering the flue without affecting the normal flow of flue gas. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a water retaining structure for a self-cleaning oil fume purifier and an oil fume purifier thereof, so as to solve the technical problems described in the background technology.

[0026] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0027] Embodiment 1:

[0028] A rolling curtain type water retaining structure for a self-cleaning oil fume purifier is mainly used to prevent dripping spray liquid from entering the flue when the oil fume purifier is sprayed and cleaned. Figure 1 As shown, the water retaining structure includes a vertical flue 2 connected to the flue inlet 1. In order to retain water and catch the falling spray liquid, a water collecting tank 3 is provided on the inner wall of the vertical flue 2. Figure 2-Figure 5 As described above, a curtain sheet 4 is arranged near the water collecting tank 3, and the curtain sheet 4 is slidably installed through two tracks 5, and the tracks 5 are installed through a bracket. A reel 6 for retracting and releasing the curtain sheet 4 is connected to the curtain sheet 4, and the reel 6 is connected to a driving mechanism for driving the axial rotation thereof, and the driving mechanism can be manually driven, such as a rocker, or automatically driven, such as a motor.

[0029] Normally, such as Figure 3 Figure 5As shown, the driving mechanism retracts the curtain 4 to the first mode through the reel 6, so that the oil smoke discharged from the flue inlet 1 flows upward to the oil smoke purifier above the vertical flue 2 for purification. This method has no obstruction and will not hinder the flow of smoke, which is conducive to the purifier's adsorption of oil smoke. When the oil smoke purifier above the vertical flue 2 needs to be sprayed and cleaned, as shown in FIG. Figure 2 Figure 4 As shown, the driving mechanism releases the curtain sheet 4 to the second mode through the reel 6, at which time the curtain sheet 4 blocks the flue inlet 1, and the positive projection of the curtain sheet 4 can completely cover the flue inlet 1, so that the spray liquid dripping from the vertical flue 2 flows into the water collection tank 3 along the curtain sheet 4, and finally a drain pipe 11 is installed on the water collection tank 3, and the spray liquid collected in the water collection tank 3 is discharged to the outside by the drain pipe 11. This water retaining structure adopts an active closing method to prevent the spray liquid from entering the flue.

[0030] It should be noted that the curtain piece 4 is a collection of multiple sheet units connected, and its structure is similar to the rolling door structure well known to those skilled in the art, and is not a single curtain piece 4 unit. In addition, the curtain piece 4 unit is a hard sheet, and when unwinding, the curtain piece 4 is restricted by the track 5, and then the reel 6 rotates, so as to push the curtain piece 4 into the track 5, so as to achieve the purpose of unfolding the curtain piece 4.

[0031] In this embodiment, the driving mechanism adopts automatic driving, such as Figure 6 As shown, the driving mechanism includes a tubular motor 7 located in the reel 6 , on which a motor driving wheel 8 and a motor crown wheel 9 are provided. The reel 6 is driven to rotate by the tubular motor 7 to realize the rolling and retracting of the curtain piece 4 .

[0032] Considering that the water retaining structure is located in the vertical flue 2, a shell cover 10 is provided on the reel 6, and a window for passing the curtain sheet 4 is provided on the shell cover 10. In this way, the reel 6 and its internal structure can be less affected by the oil smoke and dripping spray liquid.

[0033] About the installation part:

[0034] The flue inlet 1 is compatible with the smoke exhaust port of the building's public flue, making it easy to install and use. Figure 1 As shown, the flue inlet 1 is square, the vertical flue 2 is square tube-shaped, and the water collecting trough 3 is a U-shaped groove arranged on the inner wall of the vertical flue 2 and surrounded by it. Such a design can not only be integrated, but also the flue inlet 1 and the vertical flue 2 are square, which can be conducive to matching with the shape of the curtain piece 4.

[0035] There are also many ways to arrange the curtain piece 4, and this embodiment shows two:

[0036] One is in the second mode, such as Figure 4As shown, the curtain sheet 4 is horizontally arranged above the flue inlet 1 , and the spray liquid can enter the water collecting tank 3 from the edge of the curtain sheet 4 .

[0037] The other is in the second mode, such as Figure 2 As shown, the curtain piece 4 is arranged obliquely above the flue inlet 1. This manner is a preferred manner. The obliquely arranged curtain piece 4 can help guide the discharge of the spray liquid and avoid the spray liquid from accumulating on the curtain piece 4.

[0038] Embodiment 2:

[0039] A fume purifier, this embodiment adopts the water retaining structure in the first embodiment, such as Figure 7 As shown, the mechanism is that a flue outlet 12 is arranged above the vertical flue 2, and an oil fume purifier is arranged between the water retaining structure and the flue outlet 12, and the oil fume purifier is equipped with a spray-type self-cleaning device. Among them, the oil fume purifier can use an electrostatic adsorption device, which is a plurality of electrode sheets that are interlaced and non-contacting with each other. When the oil fume passes through, it is adsorbed by generating an electrostatic field. The spray-type self-cleaning device can use a nozzle, which is connected to a water pump through a pipeline, and sprays and rinses the oil fume purifier by spraying water or cleaning liquid.

[0040] This oil fume purifier is directly installed on the public flue of the building. Considering that rainwater will enter the flue on rainy days, a protective cover 13 is provided at the corresponding flue outlet 12. The protective cover 13 is used to block the top of the flue outlet 12 and guide the airflow of the flue outlet 12 to be discharged outward along the edge of the protective cover 13.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
