[0036] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

[0037] In the description of the present utility model, unless otherwise clearly specified and defined, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0038] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above the", and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below the", and "under the" second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0039] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", and "right" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] As Figure 1 and Figure 2 shown, the embodiment of the present utility model first provides an oil fume purification device for a cooking device. The cooking device includes, but is not limited to, kitchen appliances such as steam ovens, ovens, steam - baking integrated machines, etc., which generate oil fumes or steam during the cooking process. The cooking device includes an inner container and a heat dissipation air duct 200. The inner container has a cooking cavity, and high - temperature steam or high - temperature air is contained in the cooking cavity to perform steam - baking cooking on food, and oil fumes or steam are generated during the cooking process. The oil fumes and steam contain particulate matters, and the particulate matters generally include solid particulate matters and liquid particulate matters. After the cooking is completed, the cooking device uses a fan 400 to extract the oil fumes and steam in the inner container and discharge them into the oil fume purification device.

[0041] The oil fume purification device includes a purification container 1, which has a liquid inlet 11 for entering the cleaning liquid, a purification chamber 12 for containing the cleaning liquid, an inlet 13 for communicating with the inner container, and an outlet 14 for communicating with the heat dissipation air duct 200. The cleaning liquid is used to wash the oil fume entering the purification chamber 12 from the inlet 13 and absorb the particulate matter in the oil fume. The liquid inlet 11 is arranged above the inlet 13. By utilizing the characteristics of the downward flow of the cleaning liquid and the upward floating of the oil fume, along the flow direction, the cleaning liquid and the oil fume can intersect and be more fully integrated, improving the cleaning efficiency; the cleaning liquid washes and purifies the oil fume, and the particulate matter concentration in the oil fume is greatly reduced, and part of the oil fume is condensed and mixed into the cleaning liquid. At this time, the gas generated after the oil fume is purified can enter the heat dissipation air duct 200 through the outlet 14 and be discharged into the external environment.

[0042] It should be noted that the cleaning liquid in the purification chamber 12 can be clean water, which is easy to obtain and will not cause adverse effects on the components of the cooking appliance and the cooked food due to the generation of evaporation gas; the cleaning liquid in the purification chamber 12 can also be a liquid added with an alkaline treatment agent, and its absorption and purification effect is better, both of which are within the protection scope of this application.

[0043] In one embodiment, the liquid inlet 11 is arranged at the top of the purification container 1, the inlet 13 is arranged on the side of the purification container 1, and the oil fume purification device further includes an extended inlet pipe 2, which is arranged in the purification chamber 12. One end of the extended inlet pipe 2 is communicated with the inlet 13, and the other end extends below the liquid inlet 11. In this way, the cleaning liquid flows from top to bottom, and the extended inlet pipe 2 extends below the liquid inlet 11, ensuring that the cleaning liquid and the oil fume intersect at a certain angle sufficiently, and the cleaning effect is better.

[0044] Preferably, the oil fume purification device further includes an atomizing nozzle 9 to increase the uniformity of the delivery of the cleaning liquid. As Figure 4 shown, the purification container 1 forms a raised spray chamber 15 at the liquid inlet 11 to accommodate the atomizing nozzle 9. The spray chamber 15 is communicated with the purification chamber 12. The nozzle end of the atomizing nozzle 9 is arranged in the spray chamber 15 to spray the cleaning liquid towards the purification chamber 12. The atomizing nozzle 9 adopts a pressure nozzle, which can form a jet or a mist of the cleaning liquid to increase the contact area between the cleaning liquid and the oil fume, have a better condensation effect on the oil fume, save the amount of the cleaning liquid, and accelerate the purification speed. In order to ensure the pressure reliability of the pressure nozzle, the atomizing nozzle 9 has a mounting seat 91, and a sealing ring 92 is sleeved on the mounting seat 91. The spray chamber 15 is provided with a stepped mounting groove 151 at one end of the liquid inlet 11, and the mounting seat 91 sleeved with the sealing ring 92 is embedded in the mounting groove 151 to achieve a better sealing effect. The specific structure and atomization principle of the atomizing nozzle 9 can be set with reference to the prior art, and will not be elaborated in this embodiment.

[0045] Since the cleaning liquid continuously enters through the liquid inlet 11, the oil fume purification device sets a maximum liquid storage depth for the purification container 1. The inlet 13 is located above the maximum liquid storage depth to prevent the cleaning liquid from flowing back into the inlet 13, which may cause the abnormal transportation of the oil fume to be cleaned or damage to the equipment.

[0046] To ensure the reliability of the maximum liquid storage depth, the oil fume purification device further includes a water level detection component 7 and a discharge pipe 8 for discharging the cleaning liquid. One end of the discharge pipe 8 is connected to the discharge port 14. The discharge pipe 8 is provided with a liquid discharge pump 81, and the water level detection component 7 is communicatively connected to the liquid discharge pump 81. The water level detection component 7 is used to detect the liquid level of the cleaning liquid in the purification chamber 12. When the liquid level of the cleaning liquid exceeds the maximum liquid storage depth, the water level detection component 7 can send a signal, and the liquid discharge pump 81 receives the signal and starts to work, discharging the excess cleaning liquid through the discharge pipe 8 to keep the liquid level in the purification container 1 at a certain height.

[0047] To better guide the flow of the oil fume, the extended inlet pipe 2 extends obliquely downward from the end connected to the inlet 13 to the bottom of the purification chamber 12. This downward-sloping structure conforms to the flow direction of the oil fume, which can accelerate the entry of the oil fume into the purification container 1 and improve the purification efficiency. As Figure 1 shown in the figure, the angle α in the figure is the inclination angle of the extended inlet pipe 2. The size of the angle α is preferably 7°, which can fully guide the flow of the oil fume and ensure that it converges with the cleaning liquid at a certain angle.

[0048] The inner diameter of the extended inlet pipe 2 gradually increases from the end connected to the inlet 13 to the end, and the extended inlet pipe 2 is in a trumpet shape. The oil fume is dispersed during the process of flowing along the extended inlet pipe 2, and the contact with the cleaning liquid is more sufficient.

[0049] In one embodiment, the oil fume purification device further includes a heating component 3, and the heating component 3 is used to heat the cleaning liquid entering the liquid inlet 11. At high temperatures, some of the oil and grease particles in the oil fume will change their shape, undergo hydrolysis, and dissolve in water. To facilitate this solubility, the heated cleaning liquid can absorb more oil fume particles, reduce the particle concentration of the discharged oil fume, and thus improve the purification and absorption effect of the purification container 1.

[0050] In one embodiment, the cleaning liquid can come from the water tank 300 of the cooking equipment. The oil fume purification device is further provided with a liquid inlet pipe 4. One end of the liquid inlet pipe 4 is connected to the water tank 300, and the other end is connected to the liquid inlet 11. The cooking water in the water tank 300 is used as the cleaning liquid, which simplifies the structure of the oil fume purification device. At this time, the heating component 3 is connected to the liquid inlet pipe 4, and the heating component 3 heats the liquid inlet pipe 4 to achieve the purpose of heating the cleaning liquid through heat exchange in the liquid inlet pipe 4. In this way, the heating of the heating component 3 will not affect the water tank 300.

[0051] The oil fume purification device is provided with a connecting intake pipe 5. One end of the connecting intake pipe 5 is connected to the inner tank, and the other end is connected to the inlet 13 to realize the transportation of oil fume. The fan 400 is located inside the connecting intake pipe 5. A smoke detection member 51 is arranged inside the connecting intake pipe 5. The smoke detection member 51 is located at the inlet 13 and is used to detect oil fume.

[0052] The liquid inlet pipe 4 is provided with a liquid inlet pump 41 to increase the power for transporting the cleaning liquid. The smoke detection member 51 is communicatively connected to the liquid inlet pump 41. When the smoke detection member 51 detects that oil fume enters at the inlet 13, it sends a signal. The liquid inlet pump 41 receives the signal and starts to work to ensure the timeliness of the cleaning liquid.

[0053] In some embodiments, the smoke detection member 51 is communicatively connected to the heating member 3. When the smoke detection member 51 detects that oil fume enters at the inlet 13, it sends a signal. The heating member 3 receives the signal and starts to work to ensure the timeliness of heating the cleaning liquid. Of course, in order to prevent the heating member 3 from heating the liquid inlet pipe 4 empty, the time when the smoke detection member 51 sends a signal to the heating member 3 is slightly later than the time when it sends a signal to the liquid inlet pump 41, ensuring that the heating member 3 starts to work after there is cleaning liquid flowing in the liquid inlet pipe 4.

[0054] In one embodiment, the connecting intake pipe 5 includes a main pipeline 52 and a gas distribution joint 53. One end of the main pipeline 52 is connected to the inner tank, and the other end is connected to the gas distribution joint 53. The gas distribution joint 53 has a plurality of outlets 531, as Figure 3 shown. The purification container 1 is provided with a plurality of inlets 13. The outlets 531 and the inlets 13 are in one-to-one correspondence and connected. The number of outlets 531 can be set to 2 or more, not limited by the drawings of this embodiment. The gas distribution joint 53 can evenly distribute the oil fume, accelerate the amount of oil fume entering, and improve the cleaning efficiency.

[0055] The plurality of inlets 13 are arranged at intervals in the horizontal direction. Correspondingly, the oil fume purification device is provided with a plurality of extended intake pipes 2. The plurality of extended intake pipes 2 and the plurality of inlets 13 are in one-to-one correspondence and connected, so as to respectively guide the oil fume entering through the plurality of inlets 13 and better align with the liquid inlet 11.

[0056] The discharge port 14 and the inlet 13 of the oil fume purification device are arranged at opposite ends of the purification container 1, so that the oil fume can fully contact the cleaning liquid during the flow in the purification container 1. In order to improve the cleanliness of the purified gas, the oil fume purification device is further provided with an exhaust filter screen 61. The exhaust filter screen 61 is arranged at the discharge port 14. The exhaust filter screen 61 can filter large-diameter particulate matter and perform secondary purification on the gas about to be discharged. The gas after secondary purification enters the heat dissipation air duct 200 through the exhaust pipe 10 and is discharged.

[0057] In one embodiment, the fume purification device further includes a liquid drainage filter screen 62, as Figure 5 shown. A liquid drainage port 16 for discharging the cleaning liquid is provided at the bottom of the purification chamber 12, and the liquid drainage filter screen 62 is disposed at the discharge port 14. The liquid drainage filter screen 62 can adsorb and filter the particulate matters deposited in the cleaning liquid, improving the cleanliness of the discharged cleaning liquid.

[0058] To realize the circular application of the purification liquid, the fume purification device further includes a liquid supply tank. The water tank 300 partitions a part of the space to form the liquid supply tank, simplifying the structure and reducing the space occupation. The cleaning liquid circulates between the purification container 1 and the liquid supply tank, which is more environmentally friendly and will not affect the cooking water in the water tank 300.

[0059] The embodiment of the present utility model further provides a cooking device, as Figure 6 shown. The cooking device includes the fume purification device as described above. The cooking device further includes an inner container and a heat dissipation air duct 200. The purification container 1 of the fume purification device communicates with the inner container and the heat dissipation air duct 200. The purification container 1 of the fume purification device has a liquid inlet 11 for entering the cleaning liquid, a purification chamber 12 for accommodating the cleaning liquid, an inlet 13 for communicating with the inner container, and a discharge port 14 for communicating with the heat dissipation air duct 200. The cleaning liquid is used to wash the fume entering the purification chamber 12 from the inlet 13 and absorb the particulate matters in the fume. The liquid inlet 11 is disposed above the inlet 13. By using the characteristics that the cleaning liquid flows downward and the fume floats upward, along the flow direction, the cleaning liquid and the fume can meet and be more fully mixed, improving the cleaning efficiency; the cleaning liquid washes and purifies the fume, and the particulate matter concentration in the fume is greatly reduced, and part of the fume is condensed and mixed into the cleaning liquid. At this time, the gas generated after the fume is purified can enter the heat dissipation air duct 200 through the discharge port 14 and be discharged to the external environment, and the particulate matter content in the gas is less, improving the user experience of using the cooking device.

[0060] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modification, equivalent substitution and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
