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 is communicated with the cooling assembly 12; the injection pipe 14 is used to inject the low-temperature fluid into the exhaust duct 20 of the range hood 100; the exhaust pipe 16 is detachably installed in the exhaust duct 20 The condensing plate 18 is detachably arranged inside the exhaust pipe 16 ; the collecting groove 19 is detachably arranged on the inner wall of the exhaust duct 20 and is located between the injection pipe 14 and the condensation plate 18 .

In the oil fume separation device 10 according to the embodiment of the present invention, after the oil fume exchanges heat with the low-temperature fluid in the exhaust flue 20 , the oil fume after the heat exchange and cooling treatment is more likely to condense to the condensing plate 18 , and the condensed oil fume flows along the condensing plate 18 . The inner wall of the fume 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 the oil fume on the fan, thereby reducing the cleaning burden of the user, and the user can lift the fume exhaust pipe 16 upward, take out the collection The tank 19 and the condensing plate 18 are cleaned, the structure is simple, and the disassembly is convenient.

Specifically, the injection pipe 14 injects the low-temperature fluid into the exhaust duct 20 of the range hood 100, and the low-temperature fluid exchanges heat with the soot in the exhaust duct 20 to reduce the temperature of the soot particles and increase the viscosity of the cold soot particles, thereby reducing the temperature of the soot particles. The oil fume is separated from the gas flow, and then condensed to the condensing plate 18 , and the condensed oil fume particles are left along the condensing plate 18 and flow to the collecting tank 19 .

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

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

In some embodiments, the number of injection pipes 14 is multiple, and the outlets of the plurality of injection pipes 14 face the outlet direction of the flue gas exhaust duct 20 .

In this way, the direction of the low-temperature fluid sprayed by the injection pipe 14 and the flow direction of the oil fume are both directed toward the outlet direction of the flue exhaust duct 20 , which is beneficial to the heat exchange between the low-temperature fluid and the oil fume.

Specifically, the plurality of injection pipes 14 pass through the side wall of the flue exhaust duct 20 , enter the flue exhaust duct 20 from the side wall of the flue exhaust duct 20 , and after entering the flue exhaust duct 20 , bend toward the outlet of the flue exhaust duct 20 to face the exhaust duct 20 . The low temperature fluid is sprayed in the outlet direction of the flue 20 . In one embodiment, the number of injection pipes 14 is 6, and the side walls of the flue gas exhaust duct 20 are pierced at equal angular intervals. Of course, the number of injection pipes 14 is not limited to 6, and can also be 1, 2, or 2 Other quantities such as more than one can be designed with appropriate quantities and distribution intervals under actual needs.

In certain embodiments, the condensing panels 18 are disposed obliquely with respect to the axial axis 162 of the exhaust duct 16 .

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

Specifically, when the condensing plate 18 is inclined, the oil fume condensed on the condensing plate 18 will remain in the inclined direction under the action of gravity and flow to the collection tank 19 to prevent the oil fume particles from falling directly and affecting cooking. The cleaning cycle of the oil fume separation device 10 is extended.

In certain embodiments, the exhaust pipe 16 is a retractable pipe.

In this way, when the smoke exhaust device needs to be cleaned, the retractable pipe structure facilitates the disassembly of the lower smoke exhaust pipe 16 from the flue exhaust duct 20, the structure is simple, the disassembly and installation are convenient, and the user experience is improved.

Specifically, referring to FIG. 2 , when disassembling, lift the smoke exhaust pipe 16 upward to separate it from the flue exhaust duct 20 , and take out the condensing plate 18 and the collecting tank 19 for cleaning. The retractable pipe structure is convenient for disassembly.

Referring to FIG. 5, in certain embodiments, the cooling assembly 12 includes:

water tank 122;

a water pump 124, the inlet of which is in communication with the water tank 122; and

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

In this way, the fluid flowing out from the outlet of the atomizer 126 is a low-temperature liquid. After entering the injection pipe 14, the injection pipe 14 injects the low-temperature liquid into the exhaust duct 20 for heat exchange with the oil fume to increase the viscosity of the oil fume particles. It is separated from the oil fume flow to reduce the content of oil fume in the exhaust gas.

Specifically, the water pump 124 sucks the water in the water tank 122 and pressurizes it so that the water flow flows to the atomizer 126, the atomizer 126 atomizes the water flow, and the low-temperature liquid sprayed from the spray pipe 14 is the atomized water mist , which is conducive to heat exchange with oil fume. Although the water in the water tank 122 is at room temperature, the temperature of the oil fume generated during the cooking process is higher than the normal temperature. Therefore, the temperature of the low-temperature fluid processed by the cooling assembly 12 is lower than the temperature of the oil fume. Of course, the water in the water tank 122 can also be cooled water that is 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 is in communication with the outlet of the water pump 124 , and the outlet of the refrigerator 128 is in communication 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 are separated from the oil fume flow.

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

Referring to FIG. 7 , in some embodiments, the cooling assembly 12 includes a cooling fan 129 that communicates with the injection pipe 14 .

In this way, the cooling fan 129 provides low-temperature gas with a certain speed, and is ejected 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 the same as the room temperature, but the oil fume in the exhaust duct 20 is generated due to the high temperature of the oil in the pot during cooking, and the temperature of the oil fume is higher than 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 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, so that the oil fume particles are separated from the oil fume flow.

Referring to FIGS. 1 to 5 , a range hood 100 according to an embodiment of the present invention includes the range hood 10 according to any one of the above embodiments.

In the range hood 100 according to the embodiment of the present invention, after the oil fume exchanges heat with the low-temperature fluid in the flue exhaust duct 20 , the oil fume that has undergone heat exchange and cooling treatment is more likely to condense to the condensing plate 18 , and the condensed oil fume flows along the condensing plate 18 through the exhaust air. 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 on the fan, thereby reducing the cleaning burden of the user, and the user can lift the smoke exhaust pipe 16 upward and take out the collection tank 19 and the condensing plate 18 are cleaned, the structure is simple, and the disassembly is convenient.

In some embodiments, the range hood 100 includes a fume collecting hood 30 and a flue exhaust duct 20 installed on the fume collecting hood 30 .

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

Specifically, the oil fume generated during cooking 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 jet pipe 14 in the exhaust duct 20 .

In some embodiments, the range hood 100 includes a smoke exhaust fan (not shown), the smoke exhaust fan is connected to the outlet of the smoke exhaust pipe 16, the gear position of the smoke exhaust fan is adjustable, and the efficiency of the cooling assembly 12 to generate 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 the low-temperature fluid according to the air volume generated by the exhaust fan, which can save resources and improve the operation efficiency of the range hood 100 .

Specifically, when there is a lot of oil fume generated during cooking, the user can adjust the air volume of the fume exhaust fan, increase the wind power of the fume exhaust fan, and improve the efficiency of oil fume suction. In order to perform heat exchange, the cooling component 12 increases the rate of generating low-temperature fluid to meet the demand of heat exchange at this time; and when the amount of oil fume is small, the user adjusts the air volume of the fan to reduce it. When so much low-temperature fluid is required for heat exchange, the cooling component 12 reduces the rate of generating the low-temperature fluid, avoids wasting resources, and reduces the cost of use by users.
