[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] First, see Figure 1 , define the length direction of the integrated stove 10 as the X direction, define the width direction of the integrated stove 10 as the Y direction, and define the height direction and the vertical direction of the integrated stove 10 as the Z direction.

[0039] First, see Figure 1 The present application provides a head assembly 100, which is applied to an integrated stove 10. The integrated stove 10 includes a lower machine 200, a stove body 300 and a head assembly 100. The lower machine 200 mainly provides a storage cabinet space and a space for installing a range hood. The stove body 300 is mainly used to provide a stove head for cooking. The head assembly 100 is mainly used to cooperate with the range hood to generate negative pressure to absorb the oil smoke generated during cooking. It is not difficult to understand that the head assembly 100, the stove body 300 and the lower machine 200 are sequentially arranged along the Z direction and relatively fixedly connected to improve the stability of the integrated stove 10.

[0040] In some embodiments, the head assembly 100 includes a smoke collecting hood 110, which has a smoke collecting chamber 111 and an air inlet 121 connected to the smoke collecting chamber 111. The smoke collecting chamber 111 is connected to the flue of a range hood installed in the lower machine 200. In this way, the oil smoke generated during the cooking process can enter the smoke collecting chamber 111 along the air inlet 121 under the action of the negative pressure of the range hood, and finally be discharged through the flue.

[0041] In some embodiments, along the Z direction, the air inlet 121 is located on the side of the head assembly 100 away from the stove body 300. In this way, the wall of the smoke hood 110 of the head assembly 100 extending along the Z direction prevents the flame of the stove body 300 from being directly sucked into the air inlet. At the same time, the wall of the smoke hood 110 facing the stove body 300 guides the flow of oil smoke, so that the oil smoke rises along the wall of the smoke hood 110 and is then sucked into the accommodating space of the smoke hood 110.

[0042] As the function and appearance of the integrated stove 10 change, in some embodiments, the head assembly 100 also includes a smoke baffle 120, which is arranged on the top of the smoke hood 110, and at least part of the smoke baffle 120 and the stove body 300 are opposite to each other in the Z direction, so as to form a stopping and guiding effect on the oil smoke generated during the cooking process, reduce the escape of the oil smoke, make the oil smoke gather, and suck the oil smoke away under the negative pressure of the range hood.

[0043] It should be noted that the smoke shield 120 and the smoke hood 110 may be an integrated independent component, or the smoke shield 120 and the smoke hood 110 may be two components disposed separately, and the smoke shield 120 and the smoke hood 110 are relatively fixedly connected. In this way, the air inlet 121 may be disposed on the smoke shield 120 or the integrated hood.

[0044] See also Figure 1 , Figure 2 , Figure 3 In a specific embodiment, the air inlet 121 is located on the smoke baffle 120, and the air inlet 121 is located on the front side of the smoke baffle 120, that is, the air inlet 121 is located on the wall of the smoke baffle 120 along the Y direction toward the stove body 300.

[0045] In some embodiments, the smoke baffle 120 is tilted relative to the smoke hood 110 toward the stove body 300, so that the wall of the smoke baffle 120 facing the stove body 300 forms a stopping and gathering effect on the oil smoke along the Z direction, and the oil smoke further enters the smoke collecting chamber 111 through the air inlet 121 under the action of the range hood.

[0046] The structure of the smoke collecting chamber 111 affects the effect of absorbing oil smoke. In the related art, the cross-sectional profile of the smoke collecting chamber 111 is often a square structure, so that when the oil smoke enters the smoke collecting chamber 111, the oil smoke flows along the cavity wall of the smoke collecting chamber 111, that is, the cavity wall of the smoke collecting chamber 111 guides the flow of the oil smoke. However, after the oil smoke enters the smoke collecting chamber 111 through the air inlet 121, it cannot be gathered, which causes the efficiency and effect of the oil smoke absorption of the head assembly 100 to deteriorate.

[0047] In order to solve such technical defects, in one embodiment of the present application, the smoke collecting chamber 111 has a guide structure 112, and the guide structure 112 is arranged at a position of the smoke collecting chamber 111 relative to the air inlet 121 along the Y direction, so as to guide and gather the oil smoke entering from the air inlet 121 through the guide structure 112. After the oil smoke enters the smoke collecting chamber 111 through the air inlet 121, it can be concentrated at a certain position in the smoke collecting chamber 111 under the action of the guide structure 112, and then discharged through the flue under the action of the negative pressure fan, so that the range hood can improve the efficiency and effect of oil smoke removal under the same power, and further reduce the power consumption of the range hood. In the process of oil smoke flow, the guide structure 112 generates a certain flow resistance to the flow of oil smoke, further reduces the pressure before the oil smoke enters the air inlet 121 of the range hood, reduces the impact of oil smoke on the range hood, improves the stability of the integrated stove 10, and reduces the working noise of the integrated stove 10.

[0048] See also Figure 4 In some embodiments, along the transverse cross section, the flow guiding structure 112 includes at least two flow guiding sections connected in sequence. The cavity wall of the flow guiding section forms a guide for the oil smoke, so that the oil smoke flows along the cavity wall of the flow guiding section and gathers in the smoke collecting cavity 111, and then continues to flow along the smoke collecting cavity 111 to the smoke duct. At the same time, the flow guiding section forms a certain resistance to the flow of the oil smoke, so as to reduce the flow pressure of the oil smoke flowing along the smoke collecting cavity 111, and further reduce the power consumption of the integrated stove 10.

[0049] It should be noted that there may be two guide sections in the embodiment of the present application, and the two guide sections are connected in sequence along the X direction. Alternatively, there may be three or more guide sections, and three or more guide sections are connected in sequence along the X direction. The embodiment of the present application does not make specific requirements on the number of guide sections. In addition, the transverse cross section in the embodiment of the present application is parallel to the horizontal plane.

[0050] In some embodiments, the contour shapes of two adjacent guide sections are different to adjust the flow path of the oil smoke and facilitate the gathering of the oil smoke after flowing along the guide sections.

[0051] For example, along the transverse cross section, the contour shape of the guide section can be a straight line, a curve, or a combination of a straight line and a curve, etc., which is not required in the embodiments of the present application. Of two adjacent guide sections, the contour shape of one guide section can be a straight line, and the contour shape of the other guide section can be a curve.

[0052] In some embodiments, the two ends of the guide structure 112 are respectively connected to the two sides of the air inlet 121, so that the oil smoke enters the smoke collecting chamber 111 through the air inlet 121. After entering the air inlet 121, the oil smoke gradually gathers directly under the guidance of the guide structure 112.

[0053] See also Figure 4 In a specific embodiment, there are three guide sections, namely a first guide section 1121, a second guide section 1122 and a third guide section 1123. The first guide section 1121, the second guide section 1122 and the third guide section 1123 are connected in sequence along the X direction. One end of the first guide section 1121 is connected to the air inlet 121, and one end of the third guide section 1123 is connected to the air inlet 121.

[0054] In some embodiments, the contour shapes of at least two guide segments are both curves, and the bending directions and curvature radii of adjacent guide segments are different.

[0055] In the transverse cross section, the contours of the first guide segment 1121 , the second guide segment 1122 and the third guide segment 1123 are all curves.

[0056] The first guide segment 1121 and the third guide segment 1123 are bent toward the air inlet 121 along the Y direction relative to the air inlet 121, and the second guide segment 1122 is bent away from the air inlet 121 along the Y direction relative to the air inlet 121. That is, the first guide segment 1121 and the second guide segment 1122 have different bending directions, and the second guide segment 1122 and the third guide segment 1123 have different bending directions.

[0057] See also Figure 4 , the curvature of the first guide section 1121 is greater than that of the second guide section 1122, and the curvature of the third guide section 1123 is greater than that of the second guide section 1122. That is, the curvature radius of the second guide section 1122 is greater than the curvature radius of the first guide section 1121 and the curvature radius of the third guide section 1123, respectively.

[0058] The embodiment of the present application controls the flow path of the oil smoke through such a guide structure 112 to guide the oil smoke and enable the oil smoke to gather quickly. At the same time, the adjacent guide sections have different bending directions and different curvature radii, which helps to break the turbulence formed by the flow of oil smoke, further reducing the impact of the oil smoke on the smoke collecting chamber 111, thereby reducing the working noise of the head assembly 100 and the integrated stove 10.

[0059] In some embodiments, along the direction (Y) from the front side to the rear side of the smoke collecting chamber 111, the distance between the two sides of the guide structure 112 and the air inlet 121 is smaller than the distance between the middle area of ​​the guide structure 112 and the air inlet 121. In this way, since the distance between the two sides of the guide structure 112 and the air inlet 121 is smaller, the flow velocity of the oil smoke on the two sides of the guide structure 112 is increased, as well as the air intake of the air inlet 121. At the same time, the oil smoke can be evenly distributed in the middle area of ​​the guide structure 112 under the action of the guide structure 112, so as to reduce the uneven flow of the oil smoke, reduce the diffusion of the oil smoke inside and outside the smoke collecting chamber 111, and improve the efficiency and effect of oil smoke removal.

[0060] For example, see Figure 4 The first guide section 1121 and the third guide section 1123 are located on both sides of the second guide section 1122 along the X direction. The second guide section 1122 is located in the middle area of ​​the guide structure 112 relative to the guide structure 112 .

[0061] Among them, along the Y direction, the distance between the first guide section 1121 and the air inlet 121 is smaller than the distance between the second guide section 1122 and the air inlet 121; the distance between the third guide section 1123 and the air inlet 121 is also smaller than the distance between the second guide section 1122 and the air inlet 121.

[0062] Along the X direction, the distance between the part of the first guide section 1121 close to the air inlet 121 and the air inlet 121 is smaller than the distance between the part of the first guide section 1121 close to the second guide section 1122 and the air inlet 121; the distance between the part of the third guide section 1123 close to the air inlet 121 and the air inlet 121 is smaller than the distance between the part of the third guide section 1123 close to the second guide section 1122 and the air inlet 121; the distance between the part of the second guide section 1122 close to the first guide section 1121 and the air inlet 121 is smaller than the distance between the central area of ​​the second guide section 1122 close to the guide structure 112 and the air inlet 121; the distance between the part of the second guide section 1122 close to the third guide section 1123 and the air inlet 121 is smaller than the distance between the central area of ​​the second guide section 1122 close to the guide structure 112 and the air inlet 121. In this way, the contour shape of the guide structure 112 in the cross section forms a trumpet shape, which is helpful to gather the oil smoke.

[0063] In some embodiments, the smoke collecting chamber 111 further has a smoke collecting structure 113 on the side opposite to the air inlet 121, the smoke collecting structure 113 is connected to the smoke baffle 120 and forms a smoke collecting area 1131 with the smoke baffle 120, and the smoke collecting area 1131 is located between the air inlet 121 and the smoke collecting chamber 111. The smoke collecting area 1131 can collect the oil smoke entering from the air inlet 121 and enter the smoke collecting chamber 111.

[0064] See also Figure 5 Along the Y direction, the smoke collecting structure 113 is arranged on the side of the smoke baffle 120 away from the stove body 300, and the smoke collecting structure 113 is connected to the air inlet 121 and the smoke collecting chamber 111 respectively, so as to form a flow path of the oil smoke in the head assembly 100. The inner wall of the smoke collecting structure 113 and the wall surface of the smoke baffle 120 facing the smoke collecting structure 113 together form a smoke collecting area 1131. The oil smoke enters the smoke collecting area 1131 through the air inlet 121, and flows under the guidance of the inner wall of the smoke collecting area 1131, and can form a vortex to drive the oil smoke from the air inlet 121 into the smoke collecting area 1131. At the same time, it can form a gathering effect on the oil smoke at each position, so that the oil smoke can be relatively concentrated, and then discharged through the smoke collecting chamber 111 and the flue in sequence, so that the efficiency and effect of the oil smoke absorption of the head assembly 100 can be improved.

[0065] The oil smoke enters the smoke collecting area 1131 through the air inlet 121. Due to the high temperature, the oil smoke flows toward the top and gathers in the smoke collecting area 1131. At the same time, it continuously flows along the inner wall of the smoke collecting area 1131 to form a vortex, so as to drive more oil smoke into the smoke collecting area 1131 and improve the smoke collecting effect. In the embodiment of the present application, the oil smoke is promoted to gather through the joint action of the smoke collecting structure 113 and the guide structure 112, and the efficiency and effect of oil smoke removal are further improved.

[0066] In some embodiments, the lowest position of the smoke collecting structure 113 is higher than the highest position of the air inlet 121. Alternatively, the lowest position of the smoke collecting structure 113 is flush with the highest position of the air inlet 121. In this way, the smoke collecting area 1131 formed by the smoke collecting structure 113 can collect more oil smoke, further preventing the collected oil smoke from flowing back through the air inlet 121, so that the collected oil smoke is discharged as completely as possible, thereby improving the oil smoke suction effect.

[0067] See also Figure 5 , along the Z direction, the lowest position of the smoke collecting structure 113 may be the upper edge of the air inlet 121 . Alternatively, the lowest position of the smoke collecting structure 113 is higher than the upper edge of the air inlet 121 .

[0068] See also Figure 5 In some embodiments, along the transverse cross section, the cross-sectional area of ​​the smoke collecting area 1131 is larger than the cross-sectional area of ​​the smoke collecting cavity 111 on the side close to the air inlet 121 .

[0069] In the embodiment of the present application, the transverse cross-section is parallel to the horizontal plane, and the larger cross-sectional area of ​​the smoke collecting area 1131 can more effectively collect the oil smoke into the smoke collecting area 1131 through the air inlet 121, and continue to flow and gather under the action of the guide structure 112. In this way, the smoke collecting structure 113 can collect more oil smoke, further improving the efficiency and effect of the head assembly 100 in removing oil smoke.

[0070] The transverse cross-sectional area of ​​the smoke collecting chamber 111 on the side close to the air inlet 121 is relatively small. When the oil smoke flows along the air inlet 121, the smoke gathering area 1131 and the smoke collecting chamber 111, the flow areas at various positions are different. In addition, when the oil smoke flows from the smoke gathering area 1131 to the smoke collecting chamber 111, the cross-sectional area of ​​the oil smoke decreases and the flow rate of the oil smoke increases, thereby improving the efficiency and effect of the oil smoke removal of the head assembly 100.

[0071] In some embodiments, the smoke collecting structure 113 is a curved surface structure extending in the vertical direction, and the curved surface structure is curved toward the side away from the air inlet 121. By setting the curved surface structure, the surface area of ​​the smoke collecting area 1131 is increased, that is, the overall space occupancy of the smoke collecting area 1131 is increased, so as to collect more oil smoke. Furthermore, the setting of the smoke collecting area 1131 can form a certain resistance to the flow of oil smoke while collecting oil smoke, so as to reduce the pressure of oil smoke entering the smoke collecting chamber 111, thereby reducing the impact of oil smoke on the range hood, and further reducing the noise of the integrated stove 10 during operation.

[0072] It should be noted that the curved surface structure in the embodiment of the present application is a curved surface as a whole, and its surface may be an uneven or smooth curved surface. The embodiment of the present application does not make specific requirements for this.

[0073] See also Figure 5 In a specific embodiment, the smoke collecting structure 113 is an arc-shaped curved surface structure extending in the vertical direction. The arc-shaped curved surface structure is easy to process. At the same time, the oil smoke condenses on the arc-shaped curved surface, which is also convenient for users to clean. In the embodiment of the present application, the arc-shaped curved surface structure facilitates the flow of oil smoke, and the oil smoke will flow along the arc-shaped curved surface to the bottom of the head assembly 100 after condensation.

[0074] In some embodiments, the radius of curvature of the arc-shaped curved surface structure is 60-80 mm. For example, the radius of curvature of the arc-shaped curved surface structure can be 60 mm, 65 mm, 69 mm, 70 mm, 73 mm, 76 mm, 78 mm, 80 mm, etc. This embodiment of the application does not make specific requirements for this.

[0075] Combination Figure 3 , Figure 4 and Figure 6 In the embodiment of the present application, the smoke collecting hood 110 includes a first hood body 114 and a second hood body 115. The first hood body 114 and the second hood body 115 are jointly arranged to form a smoke collecting chamber 111. The smoke collecting structure 113 is arranged on the second hood body 115 and connected to the second hood body 115. The second hood body 115 is a planar structure.

[0076] It is not difficult to understand that the smoke collecting chamber 111 is formed by connecting the first cover body 114 and the second cover body 115 which are separately arranged, so as to facilitate the installation of the smoke collecting hood 110. Among them, the second cover body 115 is located on the side away from the stove body 300 along the Y direction, so as to facilitate the integrated stove 10 to fit the wall during installation, and the overall appearance of the smoke collecting hood 110 is flat. In addition, the second cover body 115 is a planar structure that supports the connection of the smoke collecting structure 113 to provide good structural stability and strength, so as to ensure that the entire smoke collecting hood 110 remains stable and not easily deformed during operation.

[0077] It should be noted that the second cover body 115 and the smoke collecting structure 113 are an integrated structure. In this way, the second cover body 115 and the smoke collecting structure 113 are an integrated independent component, and there is no gap between the second cover body 115 and the smoke collecting structure 113 to prevent oil smoke leakage. At the same time, the number of accessories used for connecting the second cover body 115 and the smoke collecting structure 113 can be reduced, the difficulty of assembling the smoke collecting hood 110 can be reduced, and the time and cost of production and installation can be reduced.

[0078] In some embodiments, see Figure 5 and Figure 6 The end of the smoke collecting structure 113 away from the second cover body 115 has a connecting portion 1132, which is bent toward the side away from the first cover body 114 and is detachably connected to the smoke baffle 120. In this way, the connecting portion 1132 of the smoke collecting structure 113 supports and connects the smoke baffle 120, so that the connection between the smoke baffle 120 and the smoke collecting hood 110 is stable.

[0079] The head assembly 100 provided in the embodiment of the present application includes: a smoke collecting hood 110 and a smoke baffle 120 arranged above the smoke collecting hood 110, the smoke collecting hood 110 has a smoke collecting chamber 111 extending in a vertical direction, and the front side of the smoke baffle 120 has an air inlet 121 connected to the smoke collecting chamber 111; the smoke collecting chamber 111 has a guide structure 112 at a position opposite to the air inlet 121, and the guide structure 112 guides the oil smoke entering from the air inlet 121, and makes the oil smoke quickly and evenly gathered in the smoke collecting chamber 111 and then discharged through the flue under the action of the negative pressure fan. In this way, the oil smoke removal efficiency and effect of the range hood can be improved under the same power, and the power consumption of the range hood can be further reduced. During the flow of oil smoke, the guide structure 112 generates a certain flow resistance to the flow of oil smoke, further reducing the pressure of the oil smoke before it enters the air inlet 121 of the range hood, reducing the impact of the oil smoke on the range hood, improving the stability of the integrated stove 10, and reducing the working noise of the integrated stove 10.

[0080] In addition, see Figure 7 and Figure 8The researchers conducted a fluid field analysis on the head assembly 100 without the guide structure 112 and the head assembly 100 with the guide structure 112, and obtained the following results: Under the same conditions, the oil fume volume of the head assembly 100 in the embodiment of the present application increased, the oil fume extraction efficiency improved, and the performance of the head assembly 100 was better than that of the head assembly 100 without the guide structure 112. At the same time, Figure 7 and Figure 8 It can be seen that the oil smoke in the smoke collecting chamber is more evenly distributed.

[0081] See also Fig. 9 and Fig.10 The researchers conducted a fluid field analysis on the head assembly 100 without the smoke-collecting structure 113 and the head assembly 100 with the smoke-collecting structure 113, and obtained the following results: Under the same conditions, the amount of oil smoke in the head assembly 100 in the embodiment of the present application increased, the oil fume extraction efficiency was improved, and the performance of the head assembly 100 was better than that of the head assembly 100 without the smoke-collecting structure 113.

[0082] By measuring the oil fume pressure drop at the air inlet 121 and the bottom of the smoke collecting chamber 111, the pressure drop of the head assembly 100 without the smoke collection structure 113 is 61.1Pa, and the pressure drop of the head assembly 100 in the embodiment of the present application is 56.5Pa. The reduced pressure drop of the head assembly 100 can reduce the energy consumption of the integrated stove 10 and improve the overall performance of the integrated stove 10.
