Referring to FIGS. 1-5 , the oil fume separation device 10 according to the embodiment of the present invention is used in a range hood 100 . The oil fume separation device 10 includes a cooling assembly 12 , an injection pipe 14 , a smoke exhaust pipe 16 , a condensation plate 18 and a collection tank 19 . The cooling assembly 12 is used to generate low-temperature fluid; the injection pipe 14 communicates with the cooling assembly 12; the injection pipe 14 is used to inject low-temperature fluid toward the exhaust duct 20 of the range hood 100; the exhaust pipe 16 is detachably mounted on the exhaust duct 20 Above; the condensing plate 18 is detachably arranged inside the exhaust pipe 16 ;

In the oil fume separation device 10 according to the embodiment of the present invention, after the oil fume is heat-exchanged with the low-temperature fluid in the flue exhaust duct 20, the oil fume treated by heat exchange and cooling is more likely to condense to the condensation plate 18, and the condensed oil fume flows along the condensation plate 18 The inner wall of the smoke exhaust pipe 16 flows to the collection tank 19, and the oil fume is effectively separated before the oil fume passes through the fan, which reduces the adhesion of oil fume to the fan, thereby reducing the cleaning burden of the user, and the user can lift the smoke exhaust pipe 16 upwards to take it out for collection. Groove 19 and condensation plate 18 are cleaned, simple in structure, easy to disassemble.

Specifically, the injection pipe 14 injects low-temperature fluid into the exhaust duct 20 of the range hood 100, and the low-temperature fluid exchanges heat with the oil fumes in the exhaust duct 20 to reduce the temperature of the oil fume particles and increase the viscosity of the oil fume cold particles. The oil fume is separated from the air flow, and then condensed to the condensation plate 18, and the condensed oil fume particles stay along the condensation plate 18 and flow to the collection tank 19.

Further, when the oil fume separation device 10 according to the embodiment of the present invention is applied to the range hood 100 , the oil fume separation device 10 can be installed on the existing range hood 100 as a whole, or can be used as a part of the new range hood 100 .

In the embodiment of the present invention, the low-temperature fluid means that the temperature of the fluid is lower than the temperature of the oil fume relative to the temperature of the oil fume generated during cooking. The fluid can be a liquid, or a gas, or a mixture of a liquid and a gas stream.

In some embodiments, there are multiple injection pipes 14 , and the exits of the plurality of injection pipes 14 are directed towards the exit of the flue exhaust duct 20 .

In this way, the direction of the low-temperature fluid ejected from the injection pipe 14 and the flow direction of the oil fume are both toward the outlet of the flue 20 , which is beneficial for heat exchange between the low-temperature fluid and the oil fume.

Specifically, a plurality of injection pipes 14 are pierced through the side wall of the exhaust duct 20, enter the exhaust duct 20 from the side wall of the exhaust duct 20, and after entering the exhaust duct 20, bend toward the exit direction of the exhaust duct 20 so as to move toward the outlet of the exhaust duct 20. The outlet direction of the flue 20 injects cryogenic fluid. In one embodiment, the number of injection pipes 14 is 6, and the side walls of the exhaust duct 20 are pierced at equiangular intervals. Of course, the number of injection pipes 14 is not limited to 6, and can also be 1, 2, or 2. More than one and other quantities, the appropriate quantity and distribution interval can be designed according to actual needs.

In some embodiments, the condensing plate 18 is inclined relative to the axial axis 162 of the exhaust pipe 16 .

In this way, after the oil fume condenses to the condensation plate 18, the inclined condensation plate 18 is conducive to the oil fume to flow down along the condensation plate 18, flow through the inner wall of the exhaust pipe 16, and then flow to the collection tank 19, which is beneficial to collect the condensed oil fume.

Specifically, when the condensing plate 18 is inclined, the oil fume condensed on the condensing plate 18, under the action of gravity, stays along the inclined direction and flows to the collection tank 19, so as to avoid the direct falling of the oil fume particles and affect the cooking. Extend the cleaning cycle of the oil fume separation device 10.

In some embodiments, the exhaust pipe 16 is a telescoping pipe.

In this way, when the smoke exhaust device needs to be cleaned, the telescopic pipe structure facilitates the removal of the smoke exhaust pipe 16 from the smoke exhaust duct 20 , the structure is simple, the disassembly and installation are convenient, and it is beneficial to improve user experience.

Specifically, please refer to Fig. 2, when disassembling, lift the exhaust pipe 16 upwards to separate it from the exhaust duct 20, and take out the condensation plate 18 and the collection tank 19 for cleaning, and the telescopic pipe structure is convenient for disassembly.

The atomizer 126 , the inlet of the atomizer 126 communicates with the outlet of the water pump 124 , and the outlet of the atomizer 126 communicates with the injection pipe 14 .

In this way, the fluid flowing out from the outlet of the atomizer 126 is a low-temperature liquid, and after entering the injection pipe 14, the injection pipe 14 sprays the low-temperature liquid into the exhaust duct 20 for heat exchange with the oil fume, so that the viscosity of the oil fume particles increases Separated from the oil fume flow, reducing the content of oil fume in the exhaust gas.

Specifically, the water pump 124 sucks the water in the water tank 122 and pressurizes the water to flow to the atomizer 126, and the atomizer 126 atomizes the water flow, and the low-temperature liquid ejected from the spray pipe 14 is atomized water mist , which is conducive to heat exchange with oil fume. Although the water in the water tank 122 is normal temperature water, the temperature of the cooking fume is higher than normal temperature. Therefore, the temperature of the low-temperature fluid processed by the cooling unit 12 is lower than the temperature of the cooking fume. Certainly, the water in the water tank 122 may also be cooled water lower than normal temperature.

Referring to FIG. 6 , in some embodiments, the cooling assembly 12 includes a refrigerator 128 , the inlet of the refrigerator 128 communicates with the outlet of the water pump 124 , and the outlet of the refrigerator 128 communicates with the inlet of the atomizer 126 .

In this way, the refrigerator 128 can further reduce the temperature of the low-temperature fluid, which is conducive to more sufficient heat exchange with the oil fume, so that the oil fume particles can be separated from the oil fume flow.

Specifically, the refrigerator 128 lowers the temperature of the water flow to be lower than normal temperature before atomizing, so that the temperature difference between the low-temperature fluid ejected from the injection pipe 14 and the oil fume increases, and the heat exchange between the low-temperature fluid and the oil fume is more sufficient. , can reduce the temperature of the soot particles to a greater extent, increase their viscosity and separate them from the soot airflow, further reduce the soot particles in the exhausted soot airflow, and help protect the air quality.

In this way, the cooling fan 129 provides low-temperature gas with a certain speed, which is sprayed from the injection pipe 14 to the exhaust duct 20 , so that the low-temperature gas exchanges heat with the oil fume in the exhaust duct 20 .

Specifically, in one example, the temperature of the low-temperature gas provided by the cooling fan 129 is consistent with the room temperature, but the oily fume in the flue 20 is produced because the temperature of the oil in the pot is too high during cooking, and the temperature of the oily fume is higher than that of the room temperature. room temperature. Therefore, the temperature of the low-temperature gas provided by the cooling fan 129 is lower than the temperature of the oil fume in the flue exhaust duct 20 .

Referring to FIG. 8 , in some embodiments, the cooling assembly 12 includes a refrigerator 128 , the inlet of the refrigerator 128 communicates with the air outlet of the cooling fan 129 , and the outlet of the refrigerator 128 communicates with the inlet of the injection pipe 14 .

In this way, the refrigerator 128 further reduces the temperature of the low-temperature gas, which is conducive to more sufficient heat exchange with the oil fume, and separates the oil fume particles from the oil fume flow.

In the range hood 100 according to the embodiment of the present invention, after the oil fume is heat-exchanged with the low-temperature fluid in the exhaust duct 20, the oil fume treated by heat exchange and cooling is more likely to condense to the condensation plate 18, and the condensed oil fume flows along the condensation plate 18 through the exhaust. The inner wall of the smoke pipe 16 flows to the collection tank 19, and the oil fume is effectively separated before the oil fume passes through the fan, which reduces the adhesion of the oil fume to the fan, thereby reducing the cleaning burden of the user, and the user can lift the smoke exhaust pipe 16 upwards to take out the collection tank 19 and condensation plate 18 are cleaned, simple in structure, easy to disassemble.

In some embodiments, the range hood 100 includes a smoke collection hood 30 and a smoke exhaust duct 20 installed on the smoke collection hood 30 .

In this way, the fume collecting hood 30 first collects the oil fume into the fume collecting hood 30, and then the oil fume enters the exhaust duct 20 and the exhaust pipe 16 to condense the oil fume. The setting of the fume collecting hood 30 can collect more oil fume, Improve smoke exhaust effect.

Specifically, the cooking fume first enters the fume collecting hood 30 , then rises to the exhaust duct 20 , and flows toward the outlet of the exhaust duct 20 together with the low-temperature fluid ejected from the injection pipe 14 in the exhaust duct 20 .

In some embodiments, the range hood 100 includes a smoke exhaust fan (not shown in the figure), the smoke exhaust fan is connected to the outlet of the smoke exhaust pipe 16, the gear of the smoke exhaust fan is adjustable, and the cooling assembly 12 produces low-temperature fluid. Adjust accordingly according to the gear of the air volume of the exhaust fan.

In this way, the cooling assembly 12 can adjust the production rate of low-temperature fluid according to the air volume generated by the smoke exhaust fan, which can save resources and improve the operating efficiency of the range hood 100 .

Specifically, when there is a lot of cooking fume, the user can adjust the gear of the air volume of the smoke exhaust fan to increase the wind power of the smoke exhaust fan and improve the efficiency of extracting the fume. After performing heat exchange, the cooling assembly 12 increases the rate of generating low-temperature fluid to meet the heat exchange requirements at this time; and when the amount of oil fume is small, the user adjusts the air volume of the fan to reduce it. With so much cryogenic fluid needed for heat exchange, the cooling assembly 12 reduces the rate of producing cryogenic fluid, avoiding waste of resources and reducing user costs.
