[0009] Wherein, the shielding plate can rotate between a first position and a second position;

[0010] When in the first position, the upper end of the shielding plate can abut against the abutting portion and be magnetically connected to the magnetic component, and the limiting portion at the lower part of the shielding plate can abut against the plate body;

[0011] In the second position, a gap is formed between the upper end of the shielding plate and the abutting portion, and the limiting portion at the lower portion of the shielding plate abuts against the rear wall of the main body to close the smoke outlet of the main body.

[0012] In the above-mentioned head assembly, the rear wall of the main body has a convex cavity protruding toward the rear side, and the convex cavity has a first wall and a second wall. The second wall is vertically arranged, and the first wall and the second wall form an angle of 150°-170°. In the first position, the first wall is parallel to the filter net, and the second wall is parallel to the main board of the baffle.

[0017] An integrated stove comprises the above-mentioned head assembly.

[0018] A method for cleaning a head assembly comprises the following steps:

[0019] S1. Ensure that the power supply of the integrated stove has been cut off and the device has been fully cooled to normal temperature;

[0020] S2.

[0024] Compared with the prior art, this application has the following advantages:

[0025] When certain specific operations are required, such as cleaning and maintenance, the baffle can be rotated from the first position to the second position. During the rotation, the baffle rotates around the positioning axis. When it reaches the second position, a gap is formed between the upper end of the baffle and the abutment portion, so that part of the area originally blocked by the baffle can be opened, which is convenient for related operations, such as cleaning of components such as the filter. At the same time, the limiting portion at the lower part of the baffle abuts against the rear wall of the main body and closes the smoke outlet of the main body. This step is mainly to prevent external impurities, tools, cleaning agents, etc. from entering the interior of the main body through the smoke outlet when performing specific operations, to ensure that the internal environment of the main body is relatively closed, and to avoid unnecessary pollution or interference during maintenance and cleaning.

[0043] The following is combined with Figure 1-Figure 7 The present application is further described with specific embodiments:

[0044] First of all, it should be noted that in the description of this application, if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and other directional words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application; in addition, if the terms "first", "second", "third" and other numerical quantifiers appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", and "connected" appear, they should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, a limited connection such as an interference fit, a transition fit, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0045] like Figures 1 to 7 As shown, a head assembly includes: a main body 2, a filter 3, and a baffle 4. The main body 2 has a smoke inlet 21 on the front side and a smoke outlet 22 located at the bottom of the main body 2. The bottom of the main body 2 has a plate body 23 that constitutes the lower boundary of the smoke inlet 21; the filter 3 is fixed to the front side of the main body 2 and blocks part of the smoke inlet 21. The lower end of the filter 3 is provided with a supporting portion 31, and at least one magnetic component 311 is fixed to the supporting portion 31; the baffle 4 is located at the bottom of the filter 3, and the baffle 4 includes a main board 41, side edges 42 located on both sides of the main board 41, and a limiting portion 43 located at the bottom of the main board 41. A card slot 421 is provided in the middle of the side edge 42. A positioning shaft 5 is fixed to the side wall 25 of the main body 2. 4 is clamped on the positioning shaft 5 through the clamping groove 421, so that the shielding plate 4 can rotate relative to the positioning shaft 5, and the shielding plate 4 can be separated from the positioning shaft 5, and the two ends of the limiting portion 43 are connected to the lower end of the side 42 to form a receiving groove 44; wherein, the shielding plate 4 can rotate between the first position and the second position; in the first position, the upper end of the shielding plate 4 can abut on the abutting portion 31 and be magnetically connected with the magnetic component 311, and the limiting portion 43 of the lower part of the shielding plate 4 can abut on the plate body 23; in the second position, a gap 6 is formed between the upper end of the shielding plate 4 and the abutting portion 31, and the limiting portion 43 of the lower part of the shielding plate 4 abuts against the rear wall 24 of the main body 2, and closes the smoke outlet 22 of the main body 2.

[0046] In the present application, under normal working conditions, the shielding plate 4 is in the first position, and the shielding plate 4 is clamped on the positioning shaft 5 fixed on the side wall 25 of the main body 2 through the clamping groove 421 in the middle of the side edges 42 on both sides, so as to realize the rotatable connection with the main body 2. At this time, the upper end of the shielding plate 4 can be abutted against the abutting part 31 at the lower end of the filter 3, and the magnetic connection is realized by means of at least one magnetic component 311 fixed on the abutting part 31, so as to ensure the stable fixation of the upper end of the shielding plate 4. At the same time, the limiting part 43 at the lower part of the shielding plate 4 can be abutted against the plate body 23 constituting the lower boundary of the smoke inlet 21. Such a setting enables the shielding plate 4 to play a certain shielding and protective role on the area below the smoke inlet 21 when in the first position, so as to prevent the abnormal flow or leakage of oil smoke in this area, and ensure that the oil smoke can enter the interior of the main body 2 through the smoke inlet 21 relatively smoothly, and be discharged from the smoke outlet 22 at the lower part of the main body 2 after other subsequent treatments.

[0047] When certain specific operations are required, such as cleaning and maintenance, the baffle plate 4 can be rotated from the first position to the second position. During the rotation, the baffle plate 4 rotates around the positioning axis 5. When it reaches the second position, a gap 6 is formed between the upper end of the baffle plate 4 and the abutment portion 31, so that part of the area originally blocked by the baffle plate 4 can be opened to facilitate related operations, such as cleaning of components such as the filter 3. At the same time, the limiting portion 43 at the lower part of the baffle plate 4 abuts against the rear wall 24 of the main body 2 and closes the smoke outlet 22 of the main body 2. This step is mainly to prevent external impurities, tools, cleaning agents, etc. from entering the interior of the main body 2 through the smoke outlet 22 when performing specific operations, thereby ensuring that the internal environment of the main body 2 is relatively closed and avoiding unnecessary pollution or interference during maintenance and cleaning.

[0048] The shielding plate 4 is designed to be clamped on the positioning shaft 5 through the clamping groove 421, so that the shielding plate 4 can rotate relative to the positioning shaft 5 to adapt to different working conditions and operating requirements, and can also be detached from the positioning shaft 5, which is convenient for completely removing the shielding plate 4 when necessary for more in-depth cleaning or component replacement. This connection method combining detachable and rotating greatly improves the overall maintainability of the head assembly. The shielding plate 4 plays different protective roles in different positions. In the first position, it protects the area below the smoke inlet 21 to ensure the normal flow of oil smoke; in the second position, it closes and protects the smoke outlet 22 to prevent external impurities from entering the interior of the main body 2. This multi-faceted protective function enables the head assembly to better protect the internal environment and ensure the working effect during the entire working process and maintenance stage.

[0049] The operation of rotating the shielding plate 4 between the first position and the second position is relatively simple, and the position conversion can be completed by only applying a proper external force to rotate it around the positioning axis 5 .

[0050] Specifically, Figure 2 , Figure 3 , Figure 4 As shown, the rear wall 24 of the main body 2 has a convex cavity 241 protruding toward the rear side, and the convex cavity 241 has a first wall 2411 and a second wall 2412. The second wall 2412 is vertically arranged, and the first wall 2411 and the second wall 2412 form an angle α, and the angle α is 150°-170°. In the first position, the first wall 2411 is parallel to the filter net 3, and the second wall 2412 is parallel to the main board 41 of the baffle plate 4.

[0051] During the operation of the integrated stove, the oil smoke needs to flow along a specific path inside the main body 2 so as to be efficiently inhaled.

[0052] When in the first position, since the first wall 2411 is parallel to the filter 3 and the second wall 2412 is parallel to the main board 41 of the shielding plate 4, this parallel relationship enables the oil smoke to continue to flow along the direction that is more in line with the first wall 2411 and the second wall 2412 after passing through the filter 3. It is like laying a "track" for the oil smoke, making it flow more smoothly and naturally, reducing the resistance caused by sudden changes in direction or air flow turbulence, and thus improving the efficiency of oil smoke exhaust.

[0053] Specifically, Figure 1-7 As shown, it also includes a storage rack 7, at least two hand-tightening nuts 8 are threadedly connected to the first wall 2411, the storage rack 7 includes a storage plate 71 and a connecting frame 72, the connecting frame 72 is fixed to the lower plate surface of the storage plate 71, the connecting frame 72 has a connecting wall 721, the connecting wall 721 can be tightly attached to the first wall 2411, and the storage plate 71 remains in a horizontal state, a bayonet 7211 is provided on the connecting wall 721, the bayonet 7211 is provided on the hand-tightening nut 8, the front end of the storage plate 71 is against the top of the main body 2, and the rear end of the storage plate 71 does not exceed the upward extension line of the second wall 2412.

[0054] The at least two hand-tightening nuts 8 threadedly connected on the first wall 2411 cooperate with the bayonet 7211 on the connecting frame 72 of the rack 7 to achieve the installation of the rack 7. This installation method does not require complicated tools. The user only needs to tighten the hand-tightening nut 8 by hand and snap it into the bayonet 7211 of the connecting wall 721 to complete the installation. The operation is simple and fast, and even non-professionals can easily complete it, which greatly reduces the difficulty of installation and improves the convenience of users when installing or disassembling the rack 7 by themselves.

[0055] The cooperation of the multiple hand-tightening nuts 8 and the bayonet 7211 forms a multi-point connection between the rack 7 and the first wall 2411 of the main body 2. Compared with a single-point connection, this multi-point connection can more evenly distribute the weight of the items carried by the rack 7.

[0056] The connecting wall surface 721 of the connecting frame 72 can be closely attached to the first wall 2411, further enhancing the stability of the storage rack 7 during use, and ensuring that the storage rack 7 can remain stable when placing items, and will not shake or fall over easily.

[0057] The front end of the storage plate 71 is against the top of the main body 2, and the rear end does not exceed the upward extension line of the second wall 2412. This design makes the spatial layout of the storage rack 7 very reasonable. It fully utilizes the space near the convex cavity 241 of the rear wall 24 of the main body 2. The storage rack 7 will not exceed the range of the main body 2 due to being too large, causing space waste or collision and interference with other components.

[0058] Specifically, Figure 2 As shown, both ends of the filter screen 3 are against the rear wall 24 of the main body 2 .

[0059] When the two ends of the filter screen 3 are against the rear wall 24 of the main body 2, a stable support structure is formed. At this time, the abutting relationship between the filter screen 3 and the rear wall 24 of the main body 2 can better resist these external forces and reduce the displacement caused by the external force.

[0060] Specifically, Figure 3 , Figure 4 As shown, two connecting ears 32 are provided on the filter 3, and the two connecting ears 32 are distributed at both ends of the abutment portion 31. Screw holes 251 corresponding to the connecting ears 32 are opened on the side wall 25 of the main body 2. When in the first position, the shielding plate 4 can shield the connecting ears 32.

[0061] The connecting ear 32 on the filter 3 and the corresponding screw hole 251 on the side wall 25 of the main body 2 can be firmly connected by bolts and other connecting parts. This connection method makes the installation of the filter 3 on the front side of the main body 2 more secure. When in the first position, the baffle plate 4 can cover the connecting ear 32, making the appearance of the entire head assembly more neat and unified.

[0062] Specifically, in the first position, the lower end of the filter 3 is farther away from the outer edge 252 of the side wall 25 of the main body 2 relative to the upper end of the filter 3, and the upper end of the baffle plate 4 is farther away from the outer edge 252 of the side wall 25 of the main body 2 relative to the lower end of the baffle plate 4. The filter 3, the baffle plate 4, and the side wall 25 of the main body 2 form a smoke gathering area 9, wherein the outer edge 252 of the side wall 25 is the edge portion of the side wall 25 of the main body 2 away from the rear wall 24.

[0063] During the operation of the integrated stove, the generated oil smoke will diffuse within a certain range. At this time, the lower end of the filter 3 is farther away from the outer edge 252 of the side wall 25 of the main body 2 than the upper end, and the upper end of the baffle 4 is farther away from the outer edge 252 of the side wall 25 of the main body 2 than the lower end. Together with the side wall 25 of the main body 2, the three together form a smoke gathering area 9. This special shape and layout enables the oil smoke to be effectively gathered in this area. After the oil smoke enters this area, the formation of the smoke gathering area 9 guides the direction of the oil smoke airflow, and it is easier to be inhaled by being blocked by the side walls 25 on both sides.

[0064] In the prior art, after the oil smoke contacts the top, it tends to escape toward both sides.

[0065] At the same time, this design can leave more space in the front area of ​​the head assembly. The baffle plate 4 and the filter screen 3 will be recessed inward, roughly corresponding to the height of the frying pan, leaving more space for flipping the pan when stir-frying.

[0066] An integrated stove comprises the above-mentioned head assembly.

[0067] A method for cleaning a head assembly comprises the following steps:

[0068] S1. Ensure that the power supply of the integrated stove has been cut off and the device has been fully cooled to normal temperature;

[0069] In step S1, it is clearly required to ensure that the power supply of the integrated stove has been cut off and the equipment has been fully cooled to room temperature. This is the first step in the entire cleaning process. By cutting off the power supply, the safety risks of electric shock, burns, etc. to the operator caused by sudden startup of the equipment due to accidental touching of the switch or electrical failure can be completely eliminated. The cooling of the equipment to room temperature avoids the possibility of burns to the operator due to high-temperature components, provides a safe and reliable environment for subsequent cleaning operations, and fully guarantees the personal safety of the operator during the cleaning process.

[0070] S2. Act precisely on the lower end of the shielding plate 4, and by applying moderate and uniform manual pressure, the shielding plate 4 is prompted to perform a smooth rotational movement around the rotation axis of the positioning shaft 5 set on the inner side wall 25 of the main body 2, and the pressure is continuously applied until the shielding plate 4 is accurately rotated to the second position. At this time, a specific gap 6 is formed between the upper end of the shielding plate 4 and the abutment portion 31 at the lower end of the filter 3, and the limiting portion 43 at the lower part of the baffle plate and the rear wall 24 of the main body 2 are in a tight abutment state, thereby ensuring that the smoke outlet 22 at the lower part of the main body 2 has been closed;

[0071] In step S2, emphasis is placed on precisely acting on the lower end of the shielding plate 4 and applying moderate and uniform manual pressure to cause it to rotate. This precise and standardized operation method helps to avoid damage to the shielding plate 4 and its connection structure with the inner wall 25 of the main body 2 due to excessive force, uneven force or improper operation. The shielding plate 4 is rotated to the correct position through a smooth rotational motion, which not only ensures that the shielding plate 4 can be smoothly switched to the second position for easy cleaning, but also maintains the structural integrity of the shielding plate 4 and related components, thereby extending the service life of the components.

[0072] S3, cleaning the inner wall of the main body 2;

[0073] During the cleaning process, the internal cleaning agent can be received and recovered through the receiving groove 44 on the shielding plate 4, thereby reducing the cleaning agent and grease from entering the volute.

[0074] S4. After the cleaning operation of the main body 2 is completed, the shielding plate 4 is disassembled and cleaned to ensure that the shielding plate 4 is restored to a clean state and meets the requirements for reuse after the cleaning is completed;

[0075] During the entire cleaning process, the shielding plate 4 is rotated to the second position and the smoke outlet 22 is closed. After the interior is cleaned, the shielding plate 4 is removed separately for cleaning to avoid secondary contamination.

[0076] S5. After the shielding plate 4 has been thoroughly cleaned and meets the cleaning standards, it is reinstalled on the positioning shaft 5 of the inner wall 25 of the main body 2 in accordance with the correct installation steps, so that it can be smoothly and accurately rotated from the second position to the first position, and achieve a stable magnetic connection with the magnetic component 311 fixed on the abutment portion 31; at the same time, the limiting portion 43 at the lower part of the shielding plate 4 again abuts against the plate body 23 forming the lower boundary of the smoke inlet 21.

[0077] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although the present application has been described in detail in this specification with reference to the above embodiments, a person of ordinary skill in the art should understand that a person of ordinary skill in the art can still modify or make equivalent substitutions to the present application, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
