Description

Technical Field

[0001] The utility model relates to an oil fume purification device, in particular to an oil fume extractor. Background Art

[0002] As an indispensable kitchen appliance in every family, the range hood sucks in oil fume from the air inlet through the high-speed rotating impeller in the volute, filters the oil fume with the impeller, and discharges the filtered oil fume from the air outlet to complete the kitchen air purification work. Reasonable air inlet setting is conducive to improving the oil fume absorption effect, reducing the escape of oil fume, and improving the air quality in the kitchen.

[0003] Range hoods are usually divided into top suction type and side suction type. Side suction range hoods usually include a range hood housing and an oil net assembly. The housing is provided with an air inlet, and oil smoke will enter the range hood from the air inlet and then be discharged from the exhaust port, as disclosed in Chinese patent application number 201922359240.1. In this type of range hood, oil smoke will adhere to the surface of the air inlet and condense into oil droplets. If the oil is not guided smoothly, it will eventually drip onto the stove surface, causing pollution. Therefore, further improvement is needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a range hood with smooth oil conduction to effectively prevent oil stains from dripping onto the stove and causing pollution in view of the deficiencies in the above-mentioned prior art.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a range hood, comprising:

[0006] The housing comprises an upper front plate and a side front plate located at the front side of the housing as a whole, wherein the side front plates have two arranged at intervals on the left and right and are respectively located under the upper front plate, and the side front plates have a first surface facing forward; and

[0007] The air inlet assembly comprises a panel bracket arranged between an upper front plate and a side front plate, and an air inlet is provided on the panel bracket; the characteristics are:

[0008] At the upper end portion where the panel bracket overlaps the upper front plate, the panel bracket protrudes forward from the first surface toward the outer surface outside the shell.

[0009] The outer surface of the upper end of the panel bracket protrudes from the second surface of the side panel, so that when the oil on the lower surface of the upper front plate flows here, it can be received by the panel bracket, thereby ensuring that the oil can flow down smoothly and effectively preventing the oil from dripping onto the stove and causing pollution.

[0010] To facilitate the fixation of the panel bracket and the shell, the lower end of the upper front panel is bent backward and downward to form a first mounting edge, the left end of the left side front panel is bent backward and right to form a second mounting edge, and the right end of the right side front panel is bent backward and left to form a third mounting edge. The periphery of the panel bracket is correspondingly provided with a flange bent backward, and the flange cooperates with the corresponding mounting edge to fix the panel bracket and each front panel.

[0011] Furthermore, a first vertical line is made at the position where the upper front plate is bent to form the first mounting edge, and the forwardmost protruding position of the upper end portion of the panel bracket is tangent to the first vertical line or extends forward beyond the first vertical line, thereby facilitating that when the oil stains on the lower surface of the upper front plate flow to this point, they can be received by the panel bracket and flow down smoothly.

[0012] Furthermore, the air inlet assembly also includes a filter screen arranged at the air inlet, so that the oil smoke can be filtered before entering the fan system.

[0013] To facilitate installation of the filter, the panel bracket is provided with an annular press profile inwardly formed at the edge of the air inlet, and the filter is fixed to the panel bracket through the press profile.

[0014] In order to facilitate the guidance of oil smoke to quickly enter the air inlet, the panel bracket is gradually recessed from the periphery to the air inlet and toward the inside of the shell.

[0015] Furthermore, the forward surface of the panel bracket from the periphery to the edge of the air inlet is the second surface, and at the upper end where the filter screen overlaps the panel bracket, the outer surface of the filter screen facing the outside of the shell protrudes forward from the second surface, so that when the oil stains on the panel bracket flow here, they can be received by the filter screen and flow down smoothly.

[0016] Furthermore, a second vertical line is made at the position where the panel bracket is bent to form a pressed shape, and the forwardmost protruding position of the upper end of the filter is tangent to the second vertical line or extends forward beyond the second vertical line. When the oil stains on the panel bracket flow to this point, they can be received by the filter and flow down smoothly.

[0017] Preferably, the upper front panel includes a first front panel and a second front panel, the first front panel extends up and down, the second front panel extends backward from the lower end of the first front panel and extends gradually downward from front to rear, and an interactive control module is arranged on the first front panel.

[0018] Preferably, in order to facilitate smoke collection and avoid smoke backflow and odor transfer when shutting down the range hood, the range hood also includes a smoke baffle that can open and close the air inlet.

[0019] Compared with the prior art, the advantages of the present invention are: the outer surface of the upper end of the panel bracket protrudes from the second surface of the side panel, so that the oil stains on the lower surface of the upper front plate can be received by the panel bracket when they flow to this place, thereby ensuring that the oil stains can flow down smoothly and effectively preventing the oil stains from dripping onto the stove and causing pollution; the outer surface of the filter screen protrudes from the second surface of the panel bracket, so that the oil stains on the panel bracket can be received by the filter screen when they flow to this place, thereby ensuring that the oil stains can flow down smoothly.

[0031] The housing 1 comprises a top plate 11, a left side plate 12, a right side plate 13, a rear plate 14, a first front plate 15 and a second front plate 16, wherein the top plate 11 extends in the front-to-back direction and is substantially horizontal. The left side plate 12 extends downward from the left end of the top plate 11, the right side plate 13 extends downward from the right end of the top plate 11, the rear plate 14 extends downward from the rear end of the top plate 11, and the first front plate 15 extends downward from the front end of the top plate 11. The left side plate 12, the right side plate 13, the rear plate 14 and the first front plate 14 are substantially vertical. The second front plate 16 extends backward from the lower end of the first front plate 15, and preferably can be gradually extended downward from the front to the back. The front end of the left side plate 12 is connected to the first front plate 15 and the second front plate 16 respectively, and the side end of the right side plate 13 is connected to the first front plate 15 and the second front plate 16 respectively. Thus, due to the inclined setting of the second front plate 16, a protruding "forehead" part is formed on the front side of the housing 1 as a whole. The first front plate 15 and the second front plate 16 together form an upper front plate.

[0032] The first front panel 15 may be provided with an interactive control module 4 for controlling the range hood gear position, power on and off, etc., such as a button, a touch screen, etc. Alternatively, the first front panel 15 may be eliminated and only the second front panel 16 may be provided, in which case the interactive control module 4 may be provided on the second front panel 16 or the fan frame 2.

[0033] The housing 1 further includes side front plates, including a third front plate 17 and a fourth front plate 18, wherein the third front plate 17 is formed by bending the front end of the left side plate 12 toward the right side plate 13 (i.e., toward the right), and the fourth front plate 18 is formed by bending the front end of the right side plate 13 toward the left side plate 12 (i.e., toward the left). The third front plate 17 and the fourth front plate 18 are both located below the second front plate 16, and the gap between the lower end of the second front plate 16 and the upper end of the third front plate 17 is as small as possible, and the gap between the lower end of the second front plate 16 and the upper end of the fourth front plate 18 is also as small as possible.

[0034] The range hood further includes an air intake assembly, which includes a panel bracket 51 and a filter 52. The panel bracket 51 is arranged between the lower end of the second front plate 16, the right end of the third front plate 17 and the left end of the fourth front plate 18, and the lower end of the panel bracket 51 can extend to the bottom of the entire housing 1. An air inlet 511 is provided on the panel bracket 51, and the filter 52 is arranged at the air inlet 511. The panel bracket 511 gradually sinks into the interior of the housing 1 from the periphery to the air inlet 511. The filter 52 is preferably a grille.

[0035] The third front plate 17 and the fourth front plate 18 are symmetrically arranged, and the front surfaces of both are recorded as the first surface 171, the front surface of the portion of the panel bracket 51 from the periphery to the edge of the air inlet 511 (i.e., the aforementioned recessed portion) is recorded as the second surface 512, and the downward surface of the second front plate 16 is recorded as the third surface 161. In this embodiment, the first surface 171 gradually tilts downward from the front to the back, the second surface 512 gradually tilts backward from the periphery to the middle air inlet 512, and the third surface 161 gradually tilts downward from the front to the back.

[0036] See also Figures 4 to 6 At the joint between the upper end of the panel bracket 51 and the second front plate 16, the outer surface of the panel bracket 51 toward the outside of the housing 1 protrudes forward from the first surface 171 ( Figure 5 The panel bracket 51 is provided to receive the grease on the third surface 161 when the grease flows to this point, thereby ensuring that the grease can flow down smoothly instead of dripping onto the stove.

[0037] At the joint between the upper end of the filter screen 52 and the panel bracket 51, the filter screen 52 protrudes forward from the second surface 512 ( Figure 6 The oil stains on the panel bracket 51 are shown by dotted lines in the figure, so that when the oil stains on the panel bracket 51 flow to this place, they can be received by the filter screen 52, thereby ensuring that the oil stains can flow down smoothly instead of dripping onto the stove.

[0038] After the oil stains on the first surface 171 gather, they flow down along the surface until they flow into the oil cup 6 at the bottom of the housing 1 .

[0039] See also Figure 7 and Figure 8 The lower end of the second front plate 16 is bent backward and downward to form a first mounting edge 191, the left end of the third front plate 17 is bent backward and rightward to form a second mounting edge 192, and the right end of the fourth front plate 18 is bent backward and leftward to form a third mounting edge 193. The periphery of the panel bracket 51 can be correspondingly provided with a flange 513 bent backward, so that each mounting edge and flange cooperates, and the panel bracket 51 can be fixed by screws, and the bottom of the panel bracket 51 is also fixed to the corresponding position of the shell 1 by screws.

[0040] The panel bracket 51 is formed with an annular pressed profile 514 inwardly at the edge of the air inlet 511 , and the filter 52 can be fixed to the panel bracket 51 (by means of screws) through the pressed profile 514 .

[0041] See also Figure 5 A first vertical line L1 is made at the bend at the lower end of the second front plate 16 (the position where the bend forms the first mounting edge 191). In order to ensure that the oil stains flow down smoothly, the forwardmost protruding position of the upper end of the panel bracket 51 needs to at least be tangent to the first vertical line L1, and preferably extend forward beyond the vertical line.

[0042] See also Figure 6 A vertical line L2 is made at the bending point corresponding to the upper end of the panel bracket 51 and the filter screen 52 (the position where the bending forms the pressed profile 514). In order to ensure that the oil and dirt flow down smoothly, the most forward protruding position of the upper end of the filter screen 52 needs to at least be tangent to this vertical line L2, and preferably extend forward beyond this vertical line.

[0043] The range hood further comprises a smoke baffle 7, which can flip open and close the air inlet 511. The smoke baffle 7 can be flipped relative to the housing 1 by a motion mechanism. The smoke baffle 7 and the motion mechanism are prior art and will not be described in detail here.
