The oil smoke absorption rate can reach more than 95%. At present, conventional integrated stoves are mostly equipped with a storage table at the head of the machine to form a smoke collection area to prevent the oil smoke from rising. When the oil smoke is large, there is still smoke leakage. Summary of the invention

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0053] During cooking, the oil smoke generated by the stove rises and fills the entire kitchen space. Integrated stoves use the principle of micro-aerodynamics, deep well exhaust or side suction exhaust, and use the principle of negative pressure generated by the exhaust to suck the oil smoke downwards. The oil smoke absorption rate can reach more than 95%. At present, conventional integrated stoves are mostly equipped with a storage table at the head of the machine to form a smoke collection area to prevent the oil smoke from rising. When the oil smoke is large, there is still smoke leakage.

[0054] To solve the above problems, please refer to Figures 1 to 3The first aspect of the present application proposes a head assembly 100. In the embodiment of the present application, the head assembly 100 includes a head 10, a storage platform 20 and a fan 30. A smoking port 121 is provided on one side of the head 10. The storage platform 20 is connected to the upper part of the head 10 and extends obliquely toward the side of the head 10 where the smoking port 121 is provided. A mounting cavity 20A is provided in the storage platform 20. The storage platform 20 is also provided with an air inlet 2211 and an air outlet 2212 communicating with the mounting cavity 20A. An air outlet slit 20B is provided at the end of the storage platform 20 away from the head 10, and the air outlet slit 20B is communicated with the air outlet 2212. Located in the mounting cavity 20A, the fan 30 is used to make the airflow entering from the air inlet 2211 flow to the air outlet 2212.

[0055] Among them, the front side of the machine head 10 is provided with a smoke inlet 121, and the smoke inlet 121 can be provided at the upper part of the machine head 10, so as to facilitate the recovery of the oil smoke flowing upward, and improve the oil smoke absorption rate. The machine head 10 includes a machine head 10 frame 206 and a smoke baffle 12, and the smoke baffle 12 is installed on the side of the machine head 10 frame 206 close to the storage table 20, and the smoke baffle 12 is provided with a smoke inlet 121. In this way, the machine head 10 frame 206 can support the machine head 10, and the smoke baffle 12 is provided at the front side of the machine head 10, and cooperates with the machine head 10 frame 206 to form an oil smoke channel of the machine head 10.

[0056] The storage table 20 is used to guide the escaped oil smoke back to the suction port 121. It can be understood that the storage table 20 is located on the side of the machine head 10 where the suction port 121 is provided to facilitate the guidance of oil smoke. The storage table 20 extends obliquely toward the side of the machine head 10 where the suction port 121 is provided, that is, the angle between the storage table 20 and the machine head 10 is an acute angle, a right angle or an obtuse angle. In the embodiment shown in the figure, the angle between the storage table 20 and the machine head 10 is an obtuse angle, and the storage table 20 is inclined upward, so that the smoke collection range is larger and the smoking effect is good.

[0057] In addition, the head 10 and the storage table 20 are in a plate shape as a whole. In this way, the volume occupied by the head assembly 100 as a whole can be reduced, which facilitates the use of the integrated kitchen appliance 1000. The smoke outlet 121 provided on the front side of the head 10 is in a rectangular shape, with the long side in the horizontal plane. The long side of the smoke outlet 121 can be as close as possible to the length of the head 10 on the side where the smoke outlet 121 is located while ensuring the strength of the head 10. In this way, the smoke intake surface can be increased and the oil smoke absorption rate can be improved.

[0058] Extending along the length direction of the storage platform 20, the air outlet slit 20B includes a smoke-collecting section 20a and a smoke-control section 20b connected to two opposite sides of the smoke-collecting section 20a. Figure 4 and Figure 5The smoke collecting section 20a is used to make the airflow flowing out of the air outlet 2212 be ejected toward the bottom of the storage table 20, and enter the smoking port 121 under the suction of the smoking port 121 to form a collecting airflow AA, and the collecting airflow AA collects the air containing the scattered oil smoke BA. Figure 6 and Figure 7 The smoke control section 20b is used to make the airflow flowing out of the air outlet 2212 form an induced airflow NA that flows along the surface of the storage table 20 toward the head 10 toward the smoking port 121, and the induced airflow NA draws air containing the escaped oil smoke BA into the smoking port 121.

[0059] Based on the head assembly 100 of the embodiment of the present application, the fan 30 directs the airflow entering from the air inlet 2211 of the storage table 20 to the air outlet 2212, and at the same time, an air outlet slit 20B connected to the air outlet 2212 is formed at the end of the storage table 20 away from the head 10. The air outlet slit 20B includes a smoke-collecting section 20a and a smoke-control section 20b connected to the opposite ends of the smoke-collecting section 20a. The smoke-collecting section 20a located in the middle ejects the airflow flowing out of the air outlet 2212 toward the bottom of the storage table 20 to form an ejected airflow AA, thereby collecting the air containing the scattered oil smoke BA, which is equivalent to extending the length of the storage table 20, further increasing the area for preventing the oil smoke from rising, so as to further suppress the dispersion of the oil smoke, and at the same time, under the suction of the smoking port 121, the scattered oil smoke BA is suppressed and sent to the smoking port 121. At the same time, the smoke control sections 20b located on both sides make the airflow out of the air outlet 2212 form an induced airflow NA that flows along the surface of the storage table 20 toward the head 10 toward the inhalation port 121, so that the air containing the escaped oil smoke BA is quickly drawn into the inhalation port 121, thereby improving the efficiency of absorbing oil smoke. Therefore, through the cooperation of the smoke collecting section 20a and the smoke control section 20b of the air outlet slit 20B, the oil smoke escape is effectively suppressed, the oil smoke absorption rate is improved, and the user experience is improved.

[0060] Optionally, the opening width of the smoke gathering section 20a is greater than the opening width of the smoke control section 20b.

[0061] Among them, the air outlet slit 20B extends along the length direction of the storage table 20, so that it can be arranged opposite to the rectangular smoking port 121 to further increase the area for suppressing the escape of oil smoke. Since the oil smoke in the middle of the storage table 20 is usually greater than the oil smoke on both sides, the opening width of the smoke-collecting section 20a is set to be larger than the opening width of the smoke-control section 20b, so that the air flow angles of different sections of the air outlet slit 20B are different to meet different needs. That is, the air flow emission direction of the smoke-control section 20b located on both sides is closer to the direction of the smoking port 121 than the air flow emission direction of the smoke-collecting section 20a located in the middle. Therefore, the gathering airflow AA formed by the smoke-collecting section 20a can increase the area for suppressing the escape of oil smoke and improve the smoke-collecting effect, and the induced airflow NA formed by the smoke-control section 20b located on both sides can quickly flow the oil smoke to the smoking port 121, further improving the oil smoke absorption rate and enhancing the user experience.

[0062] Furthermore, the opening width of the smoke collecting section 20a is greater than or equal to 3 mm and less than or equal to 4 mm. The opening width of the smoke collecting section 20a can be 3 mm, 3.5 mm, 4 mm, etc., so that the airflow direction of the jet air curtain formed by the smoke collecting section 20a can collect the air containing the escaped oil smoke BA to a large extent, that is, further increase the smoke collecting area, so as to subsequently increase the oil smoke absorption amount of the smoke collecting port 121 and improve the oil smoke absorption rate of the kitchen appliance.

[0063] Optionally, the opening width of the smoke control section 20b is greater than or equal to 1.5 mm and less than or equal to 2 mm. The opening width of the smoke collection section 20a can be 1.5 mm, 1.8 mm, 2 mm, etc., so that at both sides of the storage table 20, the flow rate of the airflow flowing along the storage table 20 to the smoking port 121 under the effect of the wall effect after the fan 30 rotates can be further increased, so as to further reduce the diffusion of oil smoke to the opposite sides of the storage table 20.

[0064] Combined with reference Figures 7 to 9 Optionally, the storage table 20 includes a first shell 21, a second shell 22 and a cover plate 23, wherein the first shell 21 is connected to the machine head 10. The second shell 22 is connected to the first shell 21 and encloses the installation cavity 20A, and the second shell 22 is provided with the air inlet 2211 and the air outlet 2212. The cover plate 23 is provided on the surface of the second shell 22 away from the first shell 21 and covers the air outlet 2212, and the cover plate 23 extends to an end of the second shell 22 away from the machine head 10, and the air outlet slit 20B is formed between the cover plate 23 and the surface of the second shell 22 away from the first shell 21.

[0065] The first housing 21 can be fixed to the machine head 10 by means of detachable connection such as screws or buckles, so as to facilitate the subsequent maintenance and disassembly of the storage platform 20. The first housing 21 and the second housing 22 can be connected by means of detachable connection such as screws or buckles, so that the storage platform 20 can be disassembled, which is convenient for the production and processing of the storage platform 20 and the subsequent installation of the fan 30.

[0066] The cover plate 23 can be directly connected and fixed to the second housing 22 or connected to other components and then fixed to the second housing 22. The cover plate 23 covers the air outlet 2212 and extends to the end of the second housing 22 away from the head 10 to form an air outlet slit 20B with the second housing 22, so that the airflow discharged from the air outlet 2212 can be guided along the air outlet slit 20B. At the same time, by changing the shape of the cover plate 23, the gap between the cover plate 23 and the air outlet 2212 is changed, and then the opening width of the air outlet slit 20B is changed, so as to control the direction and flow rate of the jet air curtain.

[0067] Further, the cover plate 23 includes a first connecting portion 231 and a first curved portion 232 connected to each other. The second shell 22 includes a second connecting portion 221 and a second curved portion 222 connected to each other, the second connecting portion 221 is connected to the first shell 21, the second connecting portion 221 is provided with the air inlet 2211 and the air outlet 2212, the first connecting portion 231 is connected to the surface of the second connecting portion 221, and the first curved portion 232 and the second curved portion 222 are arranged opposite to each other and enclose to form the air outlet slit 20B.

[0068] Among them, the first connecting portion 231 and the first curved portion 232 can be an integral structure, so as to ensure the structural strength of the cover plate 23, and further ensure the stability of the airflow passing through the air outlet slit 20B. Similarly, the second connecting portion 221 and the second curved portion 222 are also an integral structure. By forming the first curved portion 232 and the second curved portion 222 to cooperate to form the air outlet slit 20B, the air outlet slit 20B can form a jet air curtain more smoothly, ensuring the flow rate and stability of the jet air curtain, and further effectively suppressing the escape of oil smoke and improving the oil smoke absorption rate of kitchen appliances. It should be noted that the first curved portion 232 and the second curved portion 222 can be either circular arc segment profiles or other continuous curves or a combination of multiple continuous curves.

[0069] Combined with reference Figures 7 to 10Optionally, the storage table 20 further includes a flow guide member 25, the flow guide member 25 is connected to the second shell 22 and is located in the installation cavity 20A, and the flow guide member 25 is used to guide the airflow of the fan 30 to the air outlet 2212. The flow guide member 25 can be in a plate shape to facilitate processing and manufacturing, so that the plate-shaped flow guide member 25 is tilted to guide the airflow of the fan 30 to the air outlet 2212, thereby improving the air outlet efficiency. Alternatively, the flow guide member 25 can also be in a hood shape, and the hood-shaped flow guide member 25 is provided with a flow guide inlet 251 and a flow guide outlet 252, the flow guide inlet 251 is arranged opposite to the fan 30, and the flow guide outlet 252 is connected to the air outlet 2212. Thus, the volume of the flow guide member 25 can be gradually reduced along the direction from the flow guide inlet 251 to the flow guide outlet 252 to achieve the flow guide effect, or a guide surface can be formed inside the flow guide cover to guide the airflow from the flow guide inlet 251 to the flow guide outlet 252 and discharged from the air outlet 2212. In this way, the cover-shaped flow guide member 25 can cover the airflow of the fan 30 to improve the utilization rate of the airflow, thereby ensuring the stability of the subsequent formation of the jet air curtain. In addition, the contact area between the cover-shaped flow guide member 25 and the second shell 22 is large, so as to improve the stability of the flow guide member 25 after it is set.

[0070] Optionally, the air inlet 2211 is disposed on the surface of the second housing 22 facing away from the suction port 121 of the machine head 10. In this way, the air inlet 2211 is disposed on the top of the storage table 20, so that the oil smoke can be prevented from being sucked into the airflow without oil smoke from the top air inlet 2211, thereby reducing the pollution of the storage table 20 and avoiding the problem that the oil smoke pollutes the fan 30 and makes it difficult to clean.

[0071] Optionally, the air inlet 2211 is provided with a filter (not shown). In this way, the filter is provided at the air inlet 2211 to filter debris and prevent the debris from entering the interior of the storage table 20 through the air inlet 2211 and affecting the operation of the fan 30. In this way, the storage table 20 can be protected and the service life of the head assembly 100 can be increased. The filter can also be provided with a quick-release structure such as a buckle for easy cleaning and replacement.

[0072] Reference Figures 7 to 9 In another embodiment, the head assembly 100 includes a plurality of fans 30, which are arranged at intervals along the length extension direction of the first housing 21. The plurality of fans 30 can further increase the air volume of the air outlet slit 20B, thereby increasing the flow rate and stability of the jet air curtain after it is formed, thereby effectively suppressing the escape of oil smoke and improving the oil smoke absorption rate of the kitchen appliance.

[0073] Further, the second shell 22 includes a plurality of subshells 223, which are all connected to the first shell 21 and arranged at intervals along the length extension direction of the first shell 21. The plurality of subshells 223 and the first shell 21 enclose a plurality of installation cavities 20A, each of which is provided with an air inlet 2211 and an air outlet 2212, and a fan 30 is arranged in one installation cavity 20A. Along the length extension direction of the first shell 21, the air outlet 2212 of the subshell 223 located in the middle is communicated with the smoke gathering section 20a, and the air outlets 2212 of the subshells 223 located on both sides are communicated with the smoke control section 20b.

[0074] Among them, by setting multiple sub-shells 223 to cooperate with the first shell 21 to form multiple independent installation cavities 20A for installing multiple fans 30 respectively, so that each fan 30 can be installed and removed separately, which is convenient for subsequent maintenance and replacement.
