Description

Technical Field

[0001] The present invention relates to the technology of air purifiers, and particularly to an air purifier capable of sucking cooking fumes. Background Art

[0002] An air purifier, also known as an "air cleaner", air freshener, or purifier, refers to a product that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, decoration pollutants such as formaldehyde, bacteria, allergens, etc.), and effectively improve the air cleanliness. With the rapid development of modern industrial technology, air pollution is becoming more and more serious, and more and more families are using air purifiers.

[0003] Most of the existing air purifiers do not have the function of sucking cooking fumes. When stir-frying in the kitchen, the cooking fumes are usually discharged from the room through a range hood. However, the range hood is often fixed and cannot be easily moved, so its use is not flexible and convenient enough. In modern life, cooking is not necessarily carried out on a gas stove, but can also be done in an air fryer, an electric cooking pot, etc. These appliances also generate cooking fumes, and if not purified in time, it will also affect people's physical health.

[0004] After investigation, the existing Chinese patent with the patent number CN201320537683.5, "A Range Hood with an Air Purifier", includes a range hood body. The body includes an air inlet, an air outlet, and a mounting plate. The air inlet and the air outlet are connected to form an exhaust passage. A power supply, a circulation fan, a sterilization device, an electrostatic dust removal device, an air filtration device, a computer display screen, and a switch are arranged on the mounting plate. The air filtration device is arranged inside the air inlet, the fan is arranged inside the air outlet, the electrostatic dust removal device is installed between the circulation fan and the air outlet, and the sterilization device is installed between the air filtration device and the circulation fan. The air filtration device is an air purifier. This range hood has the function of purifying air, but its shape is the same as that of a traditional range hood and is also fixed on the gas stove, unable to move, and its use is not flexible and convenient enough. It can only purify the cooking fumes on the gas stove and cannot effectively purify the cooking fumes in other places. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an air purifier with a simple and reasonable structure, convenient and flexible use, and capable of sucking cooking fumes in view of the above technical status.

The rear side of the main housing 11 is formed into an installation cavity for installing the motor wind wheel assembly 8. The motor wind wheel assembly 8 is fixed in the installation cavity through a bracket. At the bottom position of the main housing 1, there is an electrical box 4. There is at least one socket 5, which is installed on the front cover plate 6 and electrically connected to the electrical box 4. The filter 9 consists of two groups of filter meshes 91 and one group of metal oil meshes 92 for filtering oil stains and grease. The metal oil mesh 92 is arranged at the forefront. In the main housing 11, there is a positioning plate 113 for positioning the filter 9 and a partition plate 111 for placing the oil stain box 7. On both sides of the oil stain box 7, there are convex L-shaped blocks 71. On the left and right sides of the inner wall of the main housing 11, there are corresponding side L-shaped slots 112. The oil stain box 7 can be detachably placed in the main housing 11 and is located directly below the metal oil mesh 92.

[0028] On the left and right sides of the front end of the upper middle part of the main housing 11, there are longitudinally arranged concave parts 114 as air inlets a. Correspondingly, on the upper middle part of the front sides of the left and right side plates 12 and 13, there are strip-shaped concave parts 121 and 131. On the lower parts of the front sides of the left and right side plates 12 and 13, there are hand holes 122 and 132 for facilitating manual upward opening of the front panel. The air outlet b is opened at the left rear position of the top cover 15. A corresponding air outlet channel is opened on the rear side of the main housing 11. A circuit board 20 is also installed at the upper end of the main housing. On the right rear side of the top cover 15, there is a touch button switch 10.

[0029] When the purifier is in the conventional air purification mode, as Figure 1 、 2 shown, the front panel 2 is closed. Air enters the housing 1 from the air inlets a on both sides of the housing 1. The purified air is filtered by the filter 9 and discharged from the air outlet b at the top of the housing 1. The flow direction of the air is as shown by the arrow in Figure 2 .

[0030] When the purifier is in the oil fume purification mode, as Figure 3 、 4 、5 shown, the cooking utensil in this embodiment is an air fryer A. Insert hands from the hand holes 122 and 132 on both sides of the housing 1, and rotate the front panel 2 to open it above the air fryer A. The rising oil fume is blocked by the front panel 2 and directly enters the housing 1 from the front end of the housing 1. After being filtered by the metal oil mesh 92, the condensed oil stains drip into the oil stain box 7. The purified air is discharged from the air outlet b at the top of the housing 1. The flow direction of the oil fume is as shown by the arrow in Figure 4 . The front panel 2 and the oil stain box 7 can be conveniently disassembled for easy cleaning.

[0031] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
