Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and more specifically to a three-chamber dual-filter range hood. Background Technology

[0002] A range hood is a type of kitchen appliance that primarily extracts cooking fumes. Grease adheres to the grease filter in the range hood, accumulates, and drips into the grease cup. The grease is then separated, and the filtered fumes are released into the air.

[0003] Existing range hoods use a single-layer filter structure, which can separate oil and fumes, but the separation effect is lacking. In addition, existing technologies cannot quickly capture the extremely dense oil fumes generated during cooking, which spread rapidly. Therefore, the oil fume filtration effect is insufficient. Utility Model Content

[0004] In view of this, the present invention provides a three-cavity dual-filter range hood.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a three-cavity dual-filter range hood, comprising: a smoke collection hood, the first side plate of the smoke collection hood being provided with a main air inlet and two auxiliary air inlets, the two auxiliary air inlets being provided on both sides of the main air inlet, the smoke collection hood forming a main smoke collection chamber and auxiliary smoke collection chambers, the main smoke collection chamber corresponding to the main air inlet, each auxiliary smoke collection chamber corresponding to one auxiliary air inlet, the main smoke collection chamber and the auxiliary smoke collection chambers being connected within the smoke collection hood;

[0006] The main air inlet is equipped with a first filter and a second filter, with the second filter located behind the first filter; the first filter has a first filter hole, and the second filter has a second filter hole.

[0007] In the direction perpendicular to the main air inlet, the first and second filter screen holes partially overlap.

[0008] In a preferred embodiment of this utility model, the first filter mesh and the second filter mesh are staggered.

[0009] In a preferred embodiment of this utility model, both the first and second filter mesh holes are elongated and parallel to each other.

[0010] As a preferred embodiment of this utility model, a gap D is left between the first filter and the second filter in the direction perpendicular to the main air inlet.

[0011] As a preferred embodiment of this utility model, a secondary oil filter screen is provided at the secondary air inlet, and an oil baffle plate is provided behind the secondary oil filter screen.

[0012] As a preferred embodiment of this utility model, a gap is left between the oil baffle and the secondary oil filter screen in the direction perpendicular to the secondary air inlet.

[0013] As a preferred embodiment of this utility model, the oil baffle is provided with a first supporting edge, and the oil baffle is fixedly installed inside the smoke collection hood through the first supporting edge.

[0014] As a preferred embodiment of the present invention, the smoke collection hood has a second side plate, with the first side plate and the second side plate facing each other; the second side plate is integrally formed with the oil baffle, and the first oil baffle protrudes from the second side plate toward the first side plate.

[0015] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0016] 1. This utility model has a first oil filter and a second oil filter at the main air inlet. The double-layer filter design provides better oil fume separation.

[0017] 2. This utility model has one main air inlet and two secondary air inlets, which provides a wider smoke extraction area and better absorbs the large amount of dense oil fumes generated during cooking. The oil fumes enter from the secondary air inlets, impact the secondary oil filter, and pass through the filter holes of the secondary oil filter to impact the oil baffle plate. The grease accumulates on the secondary oil filter and the oil baffle plate, achieving good oil and smoke separation.

[0018] 3. This utility model has a good oil fume separation effect, which reduces the amount of oil fume entering the core component area of ​​the range hood, thereby increasing the service life and effectiveness of the core components. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0031] Please refer to the three-chamber dual-filter range hood. Figure 1-6 As shown, it includes: a smoke hood 100 and a housing 200, which are internally connected. A wind power system (not shown in the figure) is installed inside the housing 200.

[0032] The first side plate 110 of the smoke hood 100 is provided with a main air inlet 111 and two secondary air inlets 112. The two secondary air inlets 112 are located on both sides of the main air inlet 111. The smoke hood 100 is characterized in that a main smoke collection chamber 101 and a secondary smoke collection chamber 102 are formed inside the smoke hood 100. The main smoke collection chamber 101 corresponds to the main air inlet 111, and each secondary smoke collection chamber 102 corresponds to one secondary air inlet 112. The main smoke collection chamber 101 and the secondary smoke collection chamber 102 are connected inside the smoke hood 100.

[0033] The main air inlet 111 is equipped with a first oil filter screen 210 and a second filter screen 220, with the second filter screen 220 located behind the first oil filter screen 210; the first oil filter screen 210 has a first filter screen hole 211, and the second filter screen 220 has a second filter screen hole 221.

[0034] In the direction perpendicular to the main air inlet 111, the first filter screen hole 211 and the second filter screen hole 221 partially overlap.

[0035] This technology features a double-layered oil filter at the main air inlet 111, which can better improve the oil and smoke separation effect;

[0036] Furthermore, the first filter mesh 211 and the second filter mesh 221 are staggered.

[0037] like Figure 4 As shown, the direction perpendicular to the reading plane is the same as the direction perpendicular to the main air inlet 111. The first filter mesh 211 and the second filter mesh 221 are arranged alternately from left to right, and the first filter mesh 211 and the second filter mesh 221 partially overlap, as shown in the figure. Figure 6 As shown, the first filter screen hole 211 is partially blocked by the second oil filter screen 220, and the second filter screen hole 221 is partially blocked by the first oil filter screen 210. Figure 6 The shaded area with the diagonal line is the overlapping area 201 of the first filter hole 211 and the second filter hole 221;

[0038] When fumes are drawn in through the main air inlet 111, they collide with the first oil filter 210, then pass through the first oil filter 210 and collide with the second oil filter 220, and then pass through the second filter hole 221 into the main smoke collection chamber 101. During this process, grease adheres to the first oil filter 210 and the second oil filter 220. Compared with a single-layer oil filter, the oil and smoke separation effect is better.

[0039] Continue as Figure 4 As shown, the first filter mesh 211 and the second filter mesh 221 are both elongated and parallel to each other. Compared with the traditional round-hole oil filter mesh, the first filter mesh 211 and the second filter mesh 221 have a larger area, which can absorb more and faster oil fumes. The double-layer filter mesh setting can ensure the oil and fume separation effect.

[0040] Furthermore, such as Figure 5 As shown, in the direction perpendicular to the main air inlet 111, there is a gap D between the first oil filter screen 210 and the second filter screen 220;

[0041] Figure 5 The direction from top to bottom is perpendicular to the main air inlet 111. The gap between the first oil filter 210 and the second filter 220 is D. The setting of the gap D can ensure that after the oil fumes pass through the first filter hole 211, they enter the gap D and then pass through the second filter hole 221 into the main smoke collection chamber 101.

[0042] If there is no gap D, the second oil filter 220 will be directly superimposed on the back of the first oil filter 210. In this case, the oil fumes can only enter the main smoke collection chamber 101 through the superimposed part of the first filter hole 211 and the second filter hole 221, which will affect the overall speed of oil fume extraction.

[0043] Furthermore, the first oil filter screen 210 and the second oil filter screen 220 are respectively made of sheet metal. In order to facilitate the positioning of the first oil filter screen 210 and the second oil filter screen 220, a pin 212 is provided at the first oil filter screen 210 and a shaft hole 222 is provided at the second oil filter screen 220. During assembly, the pin 212 passes through the shaft hole 222, so that the positions of the first oil filter screen 210 and the second oil filter screen 220 are initially positioned.

[0044] Furthermore, such as Figure 7 As shown, a secondary oil filter screen 230 is provided at the secondary air inlet 112, and an oil baffle plate 240 is provided on the rear side of the secondary oil filter screen 230.

[0045] A gap is left between the oil baffle 240 and the secondary oil filter 230 in the direction perpendicular to the secondary air inlet 112.

[0046] Furthermore, the oil baffle 240 is provided with a first support edge 241. The oil baffle 240 is fixedly installed in the smoke hood 100 through the first support edge 241. Specifically, the first support edge 241 is fixedly connected to a sheet metal part inside the smoke hood 100 by means of screws, thereby fixing the oil baffle 240 in the smoke hood 100.

[0047] During use, some oil fumes are drawn in through the secondary air inlet 112. The oil fumes collide with the secondary oil filter 230 and pass through the mesh of the secondary oil filter 230 into the gap between the oil baffle 240 and the secondary oil filter 230. Then, they collide with the oil baffle 240, and finally, the oil fumes enter the main oil collection chamber 101 from the secondary smoke collection chamber 102. During this process, grease accumulates on the secondary oil filter 230 and the oil baffle 240, achieving a good oil and smoke separation effect.

[0048] In addition, the oil baffle 240 can be installed inside the smoke hood 100, or it can be integrally formed into the smoke hood 100; specifically, such as Figure 8 As shown, the smoke hood 100 has a second side plate 120, and the first side plate 110 and the second side plate 120 are positioned opposite each other vertically; the second side plate 120 is integrally formed with the oil baffle 240, and the oil baffle 240 protrudes from the second side plate 120 toward the first side plate 110; after the second side plate 120 is installed, the oil baffle 240 corresponds to the auxiliary oil filter screen 230.

[0049] Similarly, during use, some oil fumes are drawn in from the secondary air inlet 112. The oil fumes collide with the secondary oil filter 230 and pass through the mesh of the secondary oil filter 230 into the gap between the oil baffle 240 and the secondary oil filter 230. Then, they collide with the oil baffle 240, and finally, the oil fumes enter the main oil collection chamber 101 from the secondary smoke collection chamber 102. During this process, the grease will rapidly separate from the secondary oil filter 230 and the oil baffle 240, achieving a good oil and smoke separation effect.
