Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a range hood that can purify smoke. Background Technology

[0002] Range hoods, appliances that quickly remove and vent harmful fumes from stoves and cooking processes outdoors, have become indispensable household kitchen appliances. After a period of use, although most of the fumes are removed, some remain around the range hood. This causes grease to accumulate on the hood's exterior, creating an unpleasant odor and breeding bacteria. If users don't clean the hood regularly, the grease buildup becomes increasingly difficult to remove. Cooking near such a range hood for extended periods can pose a health risk. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a range hood that can purify smoke.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A range hood capable of purifying fumes includes a range hood housing, a wind box cover for protecting the exhaust pipe is provided on the top of the range hood housing, a plurality of air inlets are provided on one side of the wind box cover on the top of the range hood housing, and a fumes purification box is installed on the inner wall of the top of the range hood housing at the air inlets.

[0006] The flue gas purification box has an internal cavity, a fan is installed on the inner wall of the flue gas purification box, and a negative ion generating mechanism is installed on one side of the fan.

[0007] In addition, a preferred structure is that a plurality of first through holes are evenly opened around the air inlet at the top of the range hood housing, and an installation port is opened at the top of the side wall of the range hood housing and on one side of the smoke purification box, and an air guide block is installed at the installation port.

[0008] In addition, a preferred structure is that the air guide block has multiple air guide openings evenly distributed along the transverse direction.

[0009] In addition, a preferred structure is that multiple mounting columns are symmetrically arranged on the inner wall of the flue gas purification box, multiple exhaust ports are evenly arranged in the transverse direction on one side wall of the flue gas purification box, and multiple second through holes for installing fans are evenly opened on the bottom wall of the flue gas purification box.

[0010] In addition, a preferred structure is that the top of the fan is provided with an air inlet, the fan is provided with an air outlet on one side of the air inlet, and fixing plates are symmetrically provided on both sides of the fan casing.

[0011] Furthermore, in a preferred configuration, the negative ion generating mechanism includes a mounting base, which is disposed on the bottom wall of the flue gas purification box. An mounting plate is mounted on the mounting base, and a negative ion generator is disposed on the mounting plate.

[0012] The beneficial effects of this utility model are as follows: By setting a smoke purification box inside the range hood casing, and blowing air through the fan inside the smoke purification box, the air blown out will pass through a negative ion generating mechanism, thereby making the air blown out of the range hood casing carry negative ions. The negative ions are free around the range hood casing, and the air carrying negative ions reacts with the particles, harmful substances, and bacteria that grow on grease in the smoke around the range hood casing, thereby reducing odors, killing bacteria, and purifying the air.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-6A range hood capable of purifying fumes includes a range hood housing 1, a wind box cover for protecting the exhaust pipe on the top of the range hood housing 1, multiple air inlets 11 on one side of the top of the range hood housing 1, a fumes purification box 2 installed on the inner wall of the top of the range hood housing 1 at the air inlets 11, a cavity inside the fumes purification box 2, a fan 4 installed on the inner wall of the fumes purification box 2, and a negative ion generating mechanism 5 installed on one side of the fan 4 for generating negative ions.

[0022] Furthermore, the top of the range hood housing 1 is provided with a plurality of first through holes 12 evenly distributed around the air inlet 11, and the top of the side wall of the range hood housing 1 is provided with an installation port 13 located on one side of the smoke purification box 2. An air guide block 3 is installed at the installation port 13, and a plurality of air guide ports 31 are evenly distributed horizontally on the upper edge of the air guide block 3. The air guide block 3 facilitates the exhaust of the air blown out by the fan 4 to the outside.

[0023] In addition, multiple mounting columns 21 are symmetrically arranged on the inner wall of the flue gas purification box 2, multiple exhaust ports 22 are evenly arranged in the transverse direction on one side wall of the flue gas purification box 2, and multiple second through holes 23 for installing the fan 4 are evenly arranged on the bottom wall of the flue gas purification box 2. Air with negative ions is blown out from the exhaust port 22.

[0024] The fan 4 has an air inlet 42 on its top and an air outlet 43 on one side of the air inlet 42. The fan 4 has fixing plates 41 symmetrically arranged on both sides of its housing. The negative ion generating mechanism 5 includes a mounting base 51, which is set on the bottom wall of the flue gas purification box 2. A mounting plate 52 is installed on the mounting base 51, and a negative ion generator 53 is set on the mounting plate 52. The negative ion generator 53 is used to generate negative ions.

[0025] In this embodiment, when the range hood is working, the fan 4 operates, and the negative ion generator 53 generates a certain concentration of negative ions. The fan 4 draws air in through the air inlet 11, the air enters the air inlet 42, and then exits from the air outlet 43, causing the air to be blown towards the negative ion generator 5 on one side and discharged from the exhaust outlet 22. The air is blown out from the air guide 31 on the air guide block 3 to one side of the range hood casing 1. During this process, the air carries the negative ions generated by the negative ion generator, thus achieving that the air blown out from the air guide block 3 carries negative ions, allowing the negative ions to circulate around the range hood casing 1. The air carrying negative ions reacts with the particles, harmful substances, and bacteria that grow on grease in the smoke around the range hood casing 1, thereby reducing odors, killing bacteria, and purifying the air.

[0026] In this invention, a smoke purification box 2 is installed inside the range hood casing 1. The fan 4 inside the smoke purification box 2 blows air through the negative ion generating mechanism 5, thereby making the air blown out of the range hood casing 1 carry negative ions. The negative ions circulate around the range hood casing 1 and react with particles, harmful substances, and bacteria growing on grease in the smoke around the range hood casing 1, thereby reducing odors, killing bacteria, and purifying the air.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
