Technical Field

[0001] The present invention belongs to the technical field of range hoods, and in particular relates to an odor-suppressing range hood capable of achieving a full-area fresh air effect. Background Art

[0002] During Chinese cooking, large particles (oil droplets, water vapor) from cooking fumes are extracted by the range hood and exhausted outdoors, reducing the air pollution caused by the fumes. However, during cooking, especially stir-frying and deep-frying, small molecules produced by the food and heated oils release volatile organic compounds (VOCs) into the indoor environment, causing the kitchen to be filled with food odors. In addition, foul odors from sewers, public flues, etc. can easily spread throughout the kitchen, seriously endangering people's health.

[0003] Existing range hoods mostly solve the problem of kitchen fumes and odors by increasing the range hood exhaust volume and improving the kitchen gas environment through air flow, but they cannot fully and effectively achieve kitchen air purification. Summary of the Invention

[0004] The purpose of the present invention is to provide an odor-suppressing range hood that can achieve a full-area fresh air effect, effectively solving the problem that existing external exhaust range hoods cannot fully and effectively achieve kitchen air purification.

[0012] Furthermore, in the ozone device, the oil filter is used to condense and settle the air inhaled by the range hood to prevent oil and dirt in the air from entering the wind cabinet; the ozone generator is used to generate ozone to purify odor molecules in the air; and the negative pressure wind wheel is used to transfer the filtered air mixed with ozone to the outlet of the wind cabinet.

[0013] Furthermore, the outlet of the box is connected to the inlet of the wind cabinet, the outlet of the wind cabinet is connected to the inlet end of the activated carbon adsorption device through a check valve, and the outlet end of the activated carbon adsorption device is connected to the inner exhaust pipe.

[0014] Furthermore, the inner pipe is connected to the kitchen space.

[0015] Furthermore, the range hood is provided with a full-area fresh air gear.

[0016] Furthermore, the power supply device is fixed on the inner wall of the wind cabinet.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are:

[0018] (1) The present invention adds an ozone generator and a negative oxygen ion generator inside the range hood, and sets the range hood's full-area fresh air gear to enable the ozone generator and the negative oxygen ion generator to work simultaneously, purify the absorbed kitchen air, and release the purified air into the kitchen environment, thereby achieving a full-area fresh air effect.

DETAILED DESCRIPTION

[0026] Example 1: A range hood capable of achieving full-range fresh air effect, with a full-range fresh air gear, which is used for operation when not cooking. Figure 1 As shown, the range hood provided in this embodiment includes a housing 1, an air cabinet 2, and an internal exhaust duct 3. A check valve 4 is mounted on the top of the air cabinet 2. This check valve 4 is externally connected to an activated carbon adsorption device 5, which is connected to the internal exhaust duct 3. Specifically, the outlet of the housing 1 is connected to the inlet of the air cabinet 2, which is connected to the inlet of the activated carbon adsorption device 5 via the check valve 4. The outlet of the activated carbon adsorption device 5 is connected to the internal exhaust duct 3, which in turn is connected to the kitchen space.

[0027] like Figure 2 As shown, an ozone device and a volute assembly are installed within the wind cabinet 2. The ozone device includes an oil filter 6, an ozone generator 7, and a negative pressure impeller 8. The volute assembly includes a volute 9, which is a conventional structure found in traditional range hoods. The ozone device is housed within the volute 9. In the ozone device, the oil filter 6 is used to condense and settle the air drawn into the range hood, preventing oil contaminants in the air from entering the wind cabinet. The ozone generator 7 is used to generate ozone to purify odor molecules in the air. The negative pressure impeller 8 rotates, delivering the filtered air mixed with ozone to the outlet of the wind cabinet 2.

[0028] like Figure 3 As shown, a negative ion generator is installed inside the outlet of the wind cabinet 2. The negative ion generator includes a power supply device 10, a sealing box 15, an ionization anode needle 11 and a conductive sheet 12. The power supply device 10 is fixed to the inner wall of the wind cabinet 2. The power supply device 10 is connected to the conductive sheet 12, and the conductive sheet 12 is connected to the ionization anode needle 11. When power is supplied by the power supply device 10, a microcurrent is transmitted between the ionization anode needle 11 and the conductive sheet 12, ionizing the ozone-mixed air passing through them, generating negative oxygen ions, and then eliminating a portion of the ozone gas. The negative oxygen ions will adsorb PM2.5 in the mixed gas and settle.

[0029] In this embodiment, if Figure 4As shown, the activated carbon adsorption device 5 includes an activated carbon honeycomb structure 13 and a fixing device 14 for fixing the activated carbon honeycomb structure 13. After passing through the negative ion generator, the mixed air is transferred upward through the check valve 4. After contacting the activated carbon adsorption device 5, most of the ozone and bacteria are adsorbed. Finally, the purified air is released into the kitchen through the internal exhaust pipe 3.

[0030] The working process of the present invention is as follows: the range hood is adjusted to the full-range fresh air gear, which is used for working when not cooking. The internal purification device is started, and the kitchen air enters the wind cabinet through the box body and first passes through the ozone device. The oil filter 6 in the ozone device will condense and settle the inhaled cooking air to prevent air oil from entering the wind cabinet 2. The ozone generator will mix the generated ozone with the filtered air to purify the odor molecules in the air. The negative pressure wind wheel 8 rotates and transmits the mixed air to the outlet through the volute device. The negative ion generator at the outlet is energized by the power supply device 10. A microcurrent will be transmitted between the ionization anode needle 11 and the conductive sheet 12, ionizing the mixed air passing therethrough to generate negative oxygen ions, thereby eliminating part of the ozone gas. The negative oxygen ions will adsorb PM2.5 in the mixed gas and settle. Then the mixed air will be transmitted upward through the check valve 4. After contacting the activated carbon adsorption device 5, most of the ozone and bacteria will be adsorbed. Finally, the purified air will be released into the kitchen through the internal exhaust pipe 3.

[0031] The range hood provided by the present invention can generate the micromolecules required for air purification by itself when working, and only needs to be powered by a power supply. It can eliminate the residual odor and PM2.5 after cooking in the kitchen, thereby achieving the effect of kitchen air purification. The released negative oxygen ions are beneficial to human comfort, and the present invention can also perform sterilization and disinfection in the kitchen.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
