[0002] The cooking of food is diverse, and its emission components are complex and variable, with high viscosity and difficult to clean. Affected by multiple factors such as cooking oil, cooking methods, dishes, and cuisines, the oil fume emitted by the catering service industry belongs to a composite organic waste gas with a large air volume, low concentration, oily sticky particles, and high water vapor, making it difficult to purify and separate. Based on the physical phenomenon of gas liquefying when cooled, there has emerged a method of liquefying and removing the oil, water, and gas in the oil fume through condensation to achieve the effect of oil fume purification.

[0003] However, after the condensation component condenses and liquefies the oil and water molecules, although most of them will drip under the action of gravity, there is still a part of the oil stain that will adhere to the condensation component, resulting in difficult contact between the oil fume and the condensation component during use, and a significant reduction in the efficiency of oil stain removal. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an oil fume cleaning structure and a range hood, which can dynamically remove the oil stain on the condensation component without the user frequently cleaning the condensation component, effectively improving the condensation efficiency of the range hood.

[0008] In a further embodiment, the angle between the condensation component and the horizontal plane is 0° to 45°.

[0009] In a further embodiment, the spraying component includes an integrally formed main pipeline and several spraying heads, and the spraying heads are arranged at intervals on the main pipeline.

[0010] In a further embodiment, the spray heads face the same direction.

[0011] In a further embodiment, the spray heads of the spray assembly face a section perpendicular to the condensation channel.

[0012] In a further embodiment, an oil baffle is provided. The oil baffle is disposed below the condensation assembly and is inclined.

[0013] In a further embodiment, a waste liquid channel is formed in the housing. The waste liquid channel is disposed on the inclined side of the oil baffle.

[0014] In a further embodiment, the projection shape of the main pipeline is a closed figure.

[0030] Embodiment 1

[0031] See Figures 1 to 3, an embodiment of the present utility model discloses an oil fume cleaning structure, which is applied to a housing 1. An oil fume passage 11 is formed inside the housing 1. The projections of the upper opening and the lower opening of the oil fume passage 11 coincide with each other. A fan 2, a condensation component for condensing oil fume, and a spraying component are provided in the oil fume passage 11. The fan 2 is arranged above the spraying component, and the spraying component is arranged above the condensation component, so that the spraying component is used to wash the oil stains on the condensation component. In this embodiment, the condensation component includes a frame 3, a fin group 31, and at least one condensation pipe 32. The frame 3 is hollow to form a condensation channel. The fin group 31 is arranged at intervals in the condensation channel. The cross-sectional shape of the fin group 31 is wavy. The condensation pipe 32 is fixed on the frame 3 and passes through the fin group 31. By arranging the condensation component in the oil fume passage 11 through which the oil fume passes, the oil gas and water vapor in the oil fume are condensed and liquefied, reducing the pollution in the oil fume. In order to further increase the collision between the oil fume and the low-temperature metal, a velvet net 33 is fixed under the condensation component. The cold quantity on the condensation component can be transferred to the velvet net 33. The honeycomb and ant-hole shapes in the velvet net 33 can effectively increase the internal area, thereby prolonging the number of collisions between the passing oil fume and the velvet net 33, and realizing more sufficient condensation and purification of the oil fume. It should be noted that the function of the honeycomb and ant-hole structure of the velvet net 33 is to increase the number of collisions of the oil fume in it by increasing the collision area. The structure of the velvet net 33 includes but is not limited to the above two structures. Other structures of the velvet net 33 that can increase the collision area are also within the protection scope of this application.

[0032] Since the condensed oil droplets are sticky and easily adsorbed in the fin group 31 and the velvet net 33, resulting in a decrease in the condensation effect and the inability to sufficiently cool and condense the oil fume when passing through, this embodiment proposes to set a spraying component above the condensation component to periodically spray the condensation component to remove the attached oil stains and ensure the purification effect of the range hood.

[0033] Specifically, the spraying component proposed in this embodiment includes an integrally formed main pipeline 4 and several spray heads 41. The spray heads 41 are arranged at intervals on the main pipeline 4. The spraying component is erected in the oil fume passage 11. In order to fully clean the condensation channel, the spray heads 41 are arranged facing the condensation channel to ensure that the spraying water can directly collide with the condensation component to remove the attached oil stains.

[0034] Preferably, the included angle between the condensation component and the horizontal plane is 0° to 45°. By setting it as a whole inclined, the liquid droplets adhering to the fin group 31 can naturally flow to the bottom and drop under the action of gravity, reducing the cleaning burden.

[0035] Preferably, an oil baffle 5 is further provided at the bottom of the oil fume passage 11. The oil baffle 5 is arranged on the lower side of the condensation assembly, and the oil baffle 5 is inclined. A waste liquid passage 12 is formed in the housing 1, and the waste liquid passage 12 is arranged on the inclined side of the oil baffle 5. The inclined oil baffle 5 can not only guide the oil droplets and water droplets condensed during the operation of the device into the waste liquid passage 12, but also guide the flushing water into the waste liquid passage 12 when the spraying assembly cleans the condensation assembly, preventing the liquid droplets from falling onto the bottom cooking range and ensuring the environmental hygiene of the kitchen.

[0036] Preferably, the projection shape of the main pipeline 4 is a closed figure. By arranging the main pipeline 4 in a ring shape or a geometric shape, the positions of the spray heads 41 can be distributed more evenly, ensuring that the upper spraying assembly can fully clean the condensation assembly.

[0037] Embodiment 2

[0038] The embodiment of the present utility model also provides an oil fume extractor, including the oil fume cleaning structure described in any one of the above. This embodiment can achieve the same beneficial effects as the above embodiments, and will not be elaborated here.

[0039] In the present utility model, a fan and a condensation assembly are arranged in the vertical oil fume passage. Under the action of the fan, the oil fume contacts the condensation assembly, and liquefaction and condensation occur, so that the oil molecules and water molecules in the oil fume are removed in the form of liquid droplets. The vertical oil fume passage also improves the efficiency of the oil fume passing through, facilitating the rapid purification of the oil fume in the kitchen environment. By arranging a spraying assembly above the condensation assembly, the attached oil stains on the condensation assembly are removed regularly, avoiding the problem of poor condensation effect during subsequent use.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
