[0034] Example 1

[0035] With the development of society and the economy and the gradual improvement of people's living standards, people are paying more and more attention to the quality of their homes, especially kitchen health. They are increasingly aware of kitchen fumes, and range hoods, as an indispensable kitchen appliance in modern homes, can quickly remove the exhaust gases and cooking fumes produced by the stove and vent them outdoors, thus purifying the kitchen environment. However, some homes do not have a shared exhaust duct in the kitchen, making it inconvenient to vent outdoors. Therefore, the demand for internal exhaust range hoods is increasing.

[0036] This embodiment provides a kitchen appliance, such as Figures 1-3 As shown, the kitchen appliance includes a main body 1, which has a smoke inlet 121 and a smoke outlet 13. A fan 15 is installed inside the main body 1. When the fan 15 is turned on, a negative pressure is generated at the smoke inlet 121, which can draw in the fumes produced during cooking. When the fumes pass through the fan 15, they are thrown against the inner wall of the fan 15 housing by the centrifugal force of the fan impeller, thereby achieving a purification effect on the fumes and preventing indoor air pollution.

[0037] However, the purification function of internal exhaust range hoods can only be achieved through the centrifugal action of the fan 15. The purification method is singular and the effect is not good. The exhaust gas will also affect the indoor air quality and raise the room temperature, which seriously affects the user experience.

[0038] like Figure 2 and Figure 3 As shown, in order to solve the above problems, the kitchen appliance provided in this embodiment also includes a purification component 2. The purification component 2 includes a purification tank 21, which contains a purification liquid. A purification channel 14 is provided in the main body 1. The air outlet of the fan 15 and the smoke outlet 13 are connected through the purification channel 14. The smoke is purified by the purification liquid in the purification channel 14.

[0039] like Figure 2 As shown, when the fan 15 of this kitchen appliance starts, it draws in flue gas through the inlet 121. After passing through the fan 15, the flue gas enters the purification channel 14 through the outlet and impacts the purification liquid. This causes larger oil fume particles in the flue gas to fall into the purification liquid. As the flue gas passes through the purification liquid, it agitates a large amount of the liquid, ensuring thorough contact between the liquid and the flue gas. The oil fume particles are captured and mixed into the purification liquid, thus completing the purification of the flue gas. Simultaneously, the purification liquid also cools the gas, preventing the gas discharged through the outlet 13 from raising the room temperature.

[0040] This kitchen appliance can purify fumes, improve indoor air quality, and prevent room temperature from rising, thus optimizing the user experience.

[0041] Specifically, the kitchen appliance also includes a flow guiding component 3, which includes a baffle 31. The bottom end of the baffle 31 extends into the purified liquid or is flush with the surface of the purified liquid. The flue gas can be purified by passing through the purified liquid under the guidance of the baffle 31.

[0042] Understandably, the baffle 31 is designed so that after the flue gas flows out of the outlet driven by the fan 15, it can flow along the baffle 31 towards the purification liquid. This ensures that the flue gas impacts the purification liquid to form waves, guaranteeing full contact between the oil fumes in the flue gas and the purification liquid. Furthermore, the waves that capture oil fume particles fall back into the purification tank 21 due to gravity, while the purified flue gas continues to move upwards, improving the purification effect. Moreover, the bottom end of the baffle 31 extends into the purification liquid or is flush with the liquid surface, allowing the flue gas to pass through the baffle 31 more easily while ensuring full contact between the flue gas and the purification liquid. This avoids increasing the resistance to flue gas flow and affecting the flue gas adsorption effect of the inlet 121.

[0043] like Figure 2 and Figure 3 As shown, the flow guiding component 3 also includes a connecting pipe 32 and a vertical plate 33. The connecting pipe 32 is connected to the air outlet, and the vertical plate 33 is connected to the bottom end of the baffle 31. The connecting pipe 32, baffle 31, vertical plate 33, purification tank 21, and main body 1 together form a purification channel 14. The connecting pipe 32 is provided with a flange, which can be fixedly connected to the flange at the air outlet of the fan 15 to ensure the reliability of the connection and avoid air leakage that would affect the ability of the smoke inlet 121 to adsorb oil fumes. The purification channel 14 formed by the connecting pipe 32, baffle 31, vertical plate 33, purification tank 21, and main body 1 is equivalent to placing the purification liquid in the purification channel 14. When the flue gas flows in the purification channel 14, it must pass through the purification liquid, ensuring the purification effect of the purification liquid on the flue gas.

[0044] In this embodiment, the purification tank 21 is disposed inside the main body 1 and located at the front end of the main body 1. The bottom surface of the connecting pipe 32 is connected to the side wall of the purification tank 21. The baffle 31 is connected to both the connecting pipe 32 and the side wall of the purification tank 21, with the bottom end of the baffle 31 spaced apart from the bottom surface of the purification tank 21. The vertical plate 33 is connected to the bottom end of the baffle 31 and extends upward. The vertical plate 33 is connected to the inner wall of the main body 1 to form a channel. That is, all the flue gas from the fan 15 passes through the gap between the baffle 31 and the bottom surface of the purification tank 21, and then through the channel between the vertical plate 33 and the inner wall of the main body 1 before being discharged from the smoke outlet 13.

[0045] It is worth noting that the smoke outlet 13 can be set at the front end, sides and top surface of the main body 1, and the smoke outlet 13 needs to be connected to the channel between the vertical plate 33 and the inner wall of the main body 1 to ensure that the purified smoke can be discharged through the smoke outlet 13.

[0046] In this embodiment, the purification component 2 further includes a diversion plate 22, which is disposed downstream of the baffle 31. The diversion plate 22 is partially disposed below the liquid surface of the purification liquid, and the lowest end of the diversion plate 22 is lower than the lowest end of the baffle 31.

[0047] The function of the diversion plate 22 is to reduce the cross-sectional area of ​​the purification channel 14 at the bottom of the baffle 31. On the one hand, it can increase the flow rate of the flue gas, and on the other hand, it can increase the height and degree of the waves agitated by the flue gas after the purification liquid is impacted by the flue gas, thereby further increasing the mixing degree between the oil fumes in the flue gas and the purification liquid, thus improving the purification effect.

[0048] like Figure 2 and Figure 3 As shown, the diversion plate 22 includes a first diversion part 221 and a partition part. The first diversion part 221 is located below the partition part and connected to the partition part. The first diversion part 221 is at least partially located below the liquid surface of the purified liquid. The first diversion part 221 is inclined to divert the flue gas.

[0049] Because the flue gas encounters significant resistance when impacting the purification liquid, its flow direction is easily altered, hindering its exit from the purification channel 14. The first guide section 221 of the guide plate 22 is located below the liquid surface. This inclined design allows the flue gas to continue flowing along the purification channel 14, minimizing the reduction in the fume extraction capacity of the inlet 121 due to changes in the flue gas flow direction.

[0050] It is worth noting that the first diversion section 221 is inclined from top to bottom, tilting upstream of the flue gas in the purification channel 14. When the flue gas impacts the purification liquid, it can flow upward under the guidance of the first diversion section 221. The second diversion section 222 can be set at an angle to the first diversion section 221. If the first diversion section 221 is vertical, the second diversion section 222 and the first diversion section 221 can also be on the same plane to increase the diversion range of the diversion plate 22 and improve the diversion effect.

[0051] In this embodiment, the guide plate 22 and the bottom surface of the purification tank 21 are spaced apart. It is understood that since the guide plate 22 is partially located above the surface of the purified liquid, when the flue gas impacts the purified liquid, some of the purified liquid will bypass the guide plate 22 and fall to the other side of the guide plate 22. At this time, the gap between the guide plate 22 and the bottom surface of the purification tank 21 ensures that the liquid level on both sides of the guide plate 22 remains constant, preventing the liquid level of the purified liquid on the side of the guide plate 22 near the baffle 31 from dropping due to a decrease in the amount of purified liquid, which could cause the baffle 31 to detach from the surface of the purified liquid and affect the purification effect of the flue gas.

[0052] It is worth noting that the kitchen appliance in this embodiment can be a range hood or an integrated stove with a fume extraction function. Both can use the purification component 2 to purify the inhaled fumes, thereby optimizing the indoor environment and preventing the room temperature from rising due to the gas discharged through the vent 13.

[0053] In this embodiment, the purifying liquid is water. Water has a high specific heat capacity, which allows it to maintain a low temperature for a long time, thus ensuring a good cooling effect. In some embodiments, the purifying liquid may also be other liquids, such as organic liquids that can dissolve oil fumes, are non-flammable, and non-toxic, to provide a better purification effect.

[0054] In this embodiment, the purification tank 21 is movably disposed within the main body 1. A push-pull opening (not shown in the figure) is provided on the side wall of the main body 1, allowing the purification tank 21 to enter and exit the main body 1 through the push-pull opening, facilitating cleaning and water replenishment by the user. It is worth noting that since the diversion plate 22 protrudes above the purification tank 21, the opening for pushing and pulling the purification tank 21 must ensure that both the purification tank 21 and the diversion plate 22 can pass through simultaneously. To ensure the integrity of the surface of the main body 1 when the purification tank 21 is pushed into the main body 1, the main body 1 is also provided with a flap (not shown in the figure), which closes the push-pull opening when the purification tank 21 is pushed into the main body 1.

[0055] Example 2

[0056] like Figures 1-3As shown, the kitchen appliance is an integrated stove. The main body 1 includes a burner head 12 and a panel 11. The burner head 12 is mounted on the panel 11, with a smoke inlet 121 and a smoke outlet 13. For ease of cooking, a burner 4 is also installed on the panel 11. When the user cooks using the burner 4, the generated fumes are drawn into the smoke inlet 121 of the burner head 12. Furthermore, under the negative pressure of the smoke inlet 121, the gas discharged from the smoke outlet 13 can also re-enter the burner head 12 under the same negative pressure. Since this gas has been cooled and purified by the purifying liquid, it pre-cools the fumes drawn into the burner head 12, thus promoting the deposition of oil fume particles.

[0057] Furthermore, the smoke outlet 13 is located on the opposite side of the burner head 12 relative to the burner 4. That is to say, when the gas discharged from the smoke outlet 13 is re-inhaled by the smoke inlet 121, its flow path will pass above the burner 4, forming an air curtain above the burner 4, so that the smoke generated during cooking can flow towards the burner head 12, improving the smoke extraction capacity and preventing the smoke from spreading and polluting the indoor air.

[0058] In this embodiment, the main body 1 also includes a cover plate 16, which is pivotally connected to the panel 11 to open or close the smoke outlet 13. When the user is not cooking, the cover plate 16 can close the smoke outlet 13. At this time, the panel 11 and the cover plate 16 form a complete plane, which can prevent water, debris, and other garbage from entering the smoke outlet 13 and contaminating the interior of the main body 1, reducing the difficulty of cleaning. It can also be used as a countertop to place tableware and other items, improving the versatility of the integrated stove. When the user is cooking, the cover plate 16 can open the smoke outlet 13, making it easier for the integrated stove to draw in smoke. Figure 2 The direction of the middle arrow indicates the direction of air circulation within the kitchen appliance.

[0059] Furthermore, the main body 1 also includes a driving member 17, which is configured to drive the cover plate 16 to rotate so that the gas passing through the smoke outlet 13 flows towards the smoke inlet 121. When the cover plate 16 is rotated to a preset angle under the drive of the driving member 17, the gas passing through the smoke outlet 13 can move towards the smoke inlet 121 under the guiding effect of the cover plate 16, so that more purified gas can be re-inhaled by the smoke inlet 121, which not only improves the pre-cooling effect of the smoke, but also enhances the air curtain, ensuring that the smoke generated during cooking does not diffuse, and improving the smoke extraction capacity.

[0060] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
