[0037] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0038] First, referring to Figure 1 , the length direction of the integrated cooker 10 is defined as the X direction, the width direction of the integrated cooker 10 is defined as the Y direction, and the height direction, vertical direction of the integrated cooker 10 is defined as the Z direction.

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

[0040] In some embodiments, the head assembly 100 includes a smoke collecting cover 110, the smoke collecting cover 110 has a smoke collecting cavity 111 and an air inlet 121 communicating with the smoke collecting cavity 111. The smoke collecting cavity 111 communicates with a flue of an extractor hood installed in the lower machine 200. In this way, oil fume generated during cooking can enter the smoke collecting cavity 111 along the air inlet 121 under the action of negative pressure of the extractor hood and finally be discharged through the flue.

[0041] In some embodiments, along the Z direction, the air inlet 121 is located on a side of the head assembly 100 away from the cooker main body 300. In this way, the wall surface of the smoke collecting cover 110 of the head assembly 100 extending along the Z direction prevents the flame of the cooker main body 300 from being directly sucked into the air inlet. Meanwhile, the wall surface of the smoke collecting cover 110 facing the cooker main body 300 guides the flow of oil fume, so that the oil fume rises along the wall surface of the smoke collecting cover 110 and is then sucked into the accommodation space of the smoke collecting cover 110.

[0042] With the change of the function and appearance of the integrated cooker 10, in some embodiments, the head assembly 100 further comprises a smoke baffle 120, which is arranged on the top of the smoke collecting cover 110. At least part of the smoke baffle 120 and the main body 300 are opposite in the Z direction to form a stop and guide effect on the oil smoke generated during cooking, reduce the dispersion of the oil smoke, so that the oil smoke is gathered and is sucked away under the negative pressure of the smoke exhaust machine.

[0043] It should be noted that the smoke baffle 120 and the smoke collecting cover 110 can be an independent component, or the smoke baffle 120 and the smoke collecting cover 110 can be two components arranged separately, and the smoke baffle 120 and the smoke collecting cover 110 are relatively fixedly connected. In this way, the air inlet 121 can be arranged on the smoke baffle 120 or the integrated cover.

[0044] Referring to 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 surface of the smoke baffle 120 facing the main body 300 in the Y direction.

[0045] In some embodiments, the smoke baffle 120 is arranged obliquely relative to the side of the smoke collecting cover 110 facing the main body 300. In this way, the wall surface of the smoke baffle 120 facing the main body 300 forms a stop and gathering effect on the oil smoke in the Z direction. The oil smoke further enters the smoke collecting cavity 111 through the air inlet 121 under the action of the smoke exhaust machine.

[0046] The structure of the smoke collecting cavity 111 affects the effect of sucking the oil smoke. In the related art, the cross-sectional profile shape of the smoke collecting cavity 111 often adopts a square structure. In this way, the oil smoke enters the smoke collecting cavity 111, and the oil smoke flows along the cavity wall of the smoke collecting cavity 111, that is, the cavity wall of the smoke collecting cavity 111 forms a guiding effect on the flow of the oil smoke. However, after the oil smoke enters the smoke collecting cavity 111 through the air inlet 121, the oil smoke cannot be gathered, which leads to poor efficiency and effect of the head assembly 100 in sucking the oil smoke.

[0047] To solve such technical defects, in an embodiment of the present application, the smoke collecting cavity 111 has a flow guide structure 112, which is arranged at a position opposite to the air inlet 121 along the Y direction, so as to guide and concentrate the oil fume entering from the air inlet 121 through the flow guide structure 112. After the oil fume enters the smoke collecting cavity 111 through the air inlet 121, it can be concentrated at a certain position in the smoke collecting cavity 111 under the action of the flow guide structure 112, and then be discharged through the flue under the action of the negative pressure fan. In this way, the oil fume extractor can improve the oil fume extraction efficiency and effect under the same power, and further reduce the power consumption of the oil fume extractor. During the flow of the oil fume, the flow guide structure 112 generates a certain flow resistance to the flow of the oil fume, further reduces the pressure of the oil fume before entering the air inlet 121 of the oil fume extractor, reduces the impact of the oil fume on the oil fume extractor, improves the stability of the integrated cooker 10, and reduces the working noise of the integrated cooker 10.

[0048] Referring to Figure 4 In some embodiments, along the transverse cross section, the flow guide structure 112 includes at least two flow guide sections connected in sequence. The flow guide sections are formed by the cavity walls of the flow guide sections to guide the oil fume, so that the oil fume flows along the cavity walls of the flow guide sections and is concentrated in the smoke collecting cavity 111, and then continues to flow to the flue along the smoke collecting cavity 111. At the same time, the flow guide sections form a certain resistance to the flow of the oil fume, so as to reduce the flow pressure of the oil fume flowing along the smoke collecting cavity 111, and further reduce the power consumption of the integrated cooker 10.

[0049] It should be noted that the flow guide sections in the embodiments of the present application can be two, and the two flow guide sections are connected in sequence along the X direction. Alternatively, the flow guide sections can be three or more, and the three flow guide sections or more flow guide sections are connected in sequence along the X direction. The number of flow guide sections is not specifically required in the embodiments of the present application. In addition, the transverse cross section in the embodiments of the present application is parallel to the horizontal plane.

[0050] In some embodiments, the profile shapes of two adjacent flow guide sections are different, so as to adjust the flow path of the oil fume and facilitate the concentration of the oil fume after flowing along the flow guide sections.

[0051] For example, along the transverse cross section, the profile shape of the flow guide section can be a straight line, a curve, or a combination of the two, and the present application does not require this. Among the two adjacent flow guide sections, the profile shape of one flow guide section can be a straight line, and the profile shape of the other flow guide section can be a curve.

[0052] In some embodiments, the two ends of the flow guide structure 112 are respectively connected with the two sides of the air inlet 121, so that the oil fume enters the smoke collecting cavity 111 through the air inlet 121, and the oil fume gradually concentrates under the guiding action of the flow guide structure 112 after entering the air inlet 121.

[0053] Referring toFigure 4 In a specific embodiment, the flow guide section is three, which are the first flow guide section 1121, the second flow guide section 1122 and the third flow guide section 1123. The first flow guide section 1121, the second flow guide section 1122 and the third flow guide section 1123 are sequentially connected along the X direction. One end of the first flow guide section 1121 is connected with the air inlet 121, and one end of the third flow guide section 1123 is connected with the air inlet 121.

[0054] In some embodiments, the profile shape of at least two flow guide sections is a curve, and the bending directions of adjacent flow guide sections are different, and the radii of curvature are different.

[0055] In the transverse cross section, the profile shape of the first flow guide section 1121, the second flow guide section 1122 and the third flow guide section 1123 is a curve.

[0056] Among them, the first flow guide section 1121 and the third flow guide section 1123 bend towards the air inlet 121 along the Y direction relative to the air inlet 121, and the second flow guide section 1122 bends away from the air inlet 121 along the Y direction relative to the air inlet 121. That is to say, the bending directions of the first flow guide section 1121 and the second flow guide section 1122 are different, and the bending directions of the second flow guide section 1122 and the third flow guide section 1123 are different.

[0057] Referring to Figure 4 , the bending degree of the first flow guide section 1121 is greater than the bending degree of the second flow guide section 1122, and the bending degree of the third flow guide section 1123 is greater than the bending degree of the second flow guide section 1122. That is, the radius of curvature of the second flow guide section 1122 is greater than the radius of curvature of the first flow guide section 1121 and the radius of curvature of the third flow guide section 1123, respectively.

[0058] The embodiments of the present application control the flow path of the oil fume by such a flow guide structure 112, so as to guide the oil fume and make the oil fume quickly gather. At the same time, the bending directions of adjacent flow guide sections are different, and the radii of curvature are different, which helps to break the turbulent flow formed by the oil fume in the flow, further reduces the impact of the oil fume on the smoke collecting cavity 111, and thus reduces the working noise of the machine head assembly 100 and the integrated stove 10.

[0059] In some embodiments, along the direction (Y) from the front side to the back side of the smoke collection cavity 111, the distance between the two sides of the flow guide structure 112 and the air inlet 121 is smaller than the distance between the middle region of the flow guide structure 112 and the air inlet 121. In this way, due to the smaller distance between the two sides of the flow guide structure 112 and the air inlet 121, the flow rate of the oil fume at the two sides of the flow guide structure 112 is increased, and the air inlet amount of the air inlet 121 is increased. At the same time, the oil fume can be uniformly distributed in the middle region of the flow guide structure 112 under the action of the flow guide structure 112, so as to reduce the uneven flow of the oil fume and reduce the diffusion of the oil fume inside and outside the smoke collection cavity 111, thereby improving the oil fume suction efficiency and effect.

[0060] For example, referring to Figure 4 , the first flow guide section 1121 and the third flow guide section 1123 are located on the two sides of the second flow guide section 1122 along the X direction, and the second flow guide section 1122 is located in the middle region of the flow guide structure 112.

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

[0062] Along the X direction, the distance between the part of the first flow 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 flow guide section 1121 close to the second flow guide section 1122 and the air inlet 121; the distance between the part of the third flow 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 flow guide section 1123 close to the second flow guide section 1122 and the air inlet 121; the distance between the part of the second flow guide section 1122 close to the first flow guide section 1121 and the air inlet 121 is smaller than the distance between the part of the second flow guide section 1122 close to the center region of the flow guide structure 112 and the air inlet 121; the distance between the part of the second flow guide section 1122 close to the third flow guide section 1123 and the air inlet 121 is smaller than the distance between the part of the second flow guide section 1122 close to the center region of the flow guide structure 112 and the air inlet 121. In this way, the profile shape of the flow guide structure 112 in the cross section forms a horn shape, which is helpful for the oil fume to be gathered.

[0063] In some embodiments, the side of the smoke collection cavity 111 opposite to the air inlet 121 also has a smoke gathering structure 113, the smoke gathering structure 113 is connected with the smoke baffle 120 and forms a smoke gathering area 1131 between the smoke gathering structure 113 and the smoke baffle 120, and the smoke gathering area 1131 is located between the air inlet 121 and the smoke collection cavity 111. The smoke gathering area 1131 can gather the oil fume entering the air inlet 121 and enter the smoke collection cavity 111.

[0064] Referring to Figure 5 , along the Y direction, the smoke gathering structure 113 is arranged on the side of the smoke blocking plate 120 away from the main body 300, and the smoke gathering structure 113 is respectively communicated with the air inlet 121 and the smoke collecting cavity 111 to form the flow path of the oil fume in the machine head assembly 100. The inner wall of the smoke gathering structure 113, the wall surface of the smoke blocking plate 120 facing the smoke gathering structure 113 together enclose the smoke gathering area 1131. The oil fume enters the smoke gathering area 1131 through the air inlet 121 and flows under the guidance of the inner wall of the smoke gathering area 1131, which can form a vortex to drive the oil fume into the smoke gathering area 1131 from the air inlet 121, and can also gather the oil fume at different positions to make the oil fume relatively concentrated, and then pass through the smoke collecting cavity 111 and the flue in turn. In this way, the efficiency and effect of the machine head assembly 100 in sucking the oil fume can be improved.

[0065] The oil fume enters the smoke gathering area 1131 through the air inlet 121, and the oil fume flows like the top due to high temperature and gathers in the smoke gathering area 1131, and continuously flows along the inner wall of the smoke gathering area 1131 to form a vortex to drive more oil fume into the smoke gathering area 1131 to improve the smoke gathering effect. In the embodiment of the present application, the oil fume is gathered by the combined action of the smoke gathering structure 113 and the flow guiding structure 112, and the efficiency and effect of the oil fume suction are further improved.

[0066] In some embodiments, the lowest position of the smoke gathering structure 113 is higher than the highest position of the air inlet 121. Alternatively, the lowest position of the smoke gathering structure 113 is flush with the highest position of the air inlet 121. In this way, the smoke gathering area 1131 formed by the smoke gathering structure 113 can gather more oil fume, and further prevent the gathered oil fume from flowing back through the air inlet 121, so that the gathered oil fume is discharged as much as possible, and the oil fume suction effect is improved.

[0067] Referring to Figure 5 , along the Z direction, the lowest position of the smoke gathering structure 113 can be the upper edge of the air inlet 121. Alternatively, the lowest position of the smoke gathering structure 113 is higher than the upper edge of the air inlet 121.

[0068] Referring to Figure 5 , in some embodiments, along the transverse cross section, the cross-sectional area of the smoke gathering area 1131 is greater than the cross-sectional area of the side of the smoke collecting cavity 111 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 gathering area 1131 can more effectively gather the oil fume through the air inlet 121 into the smoke gathering area 1131, and continuously flow and gather under the action of the flow guiding structure 112. In this way, the smoke gathering structure 113 can collect more oil fume, and further improve the efficiency and effect of the machine head assembly 100 in sucking the oil fume.

[0070] The transverse cross-sectional area of the smoke collecting cavity 111 close to the air inlet 121 is relatively small. During the flow of the oil fume along the air inlet 121, the smoke collecting area 1131 and the smoke collecting cavity 111, the flow areas at different positions are different, and during the flow from the smoke collecting area 1131 to the smoke collecting cavity 111, the cross-sectional area of the oil fume flow decreases, and the flow rate of the oil fume increases, so that the efficiency and effect of the oil fume suction of the hood assembly 100 are improved.

[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 away from the air inlet 121. By arranging the curved surface structure, the surface area of the smoke collecting area 1131 is increased, that is, the overall space ratio of the smoke collecting area 1131 is increased, so as to collect more oil fume. Further, the arrangement of the smoke collecting area 1131 can form a certain resistance to the flow of the oil fume while collecting the oil fume, so as to reduce the pressure of the oil fume entering the smoke collecting cavity 111, thereby reducing the impact of the oil fume on the range hood, and further reducing the noise of the integrated cooker 10 during operation.

[0072] It should be noted that the curved surface structure in the embodiments of the present application is a curved surface as a whole, and the surface thereof can be uneven or smooth. The embodiments of the present application do not make specific requirements thereon.

[0073] Referring to 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 convenient to process. At the same time, the oil fume condenses on the arc-shaped curved surface, which is also convenient for the user to clean. In the embodiments of the present application, the arc-shaped curved surface structure is beneficial to the flow of the oil fume, and the oil fume condenses on the arc-shaped curved surface and flows to the bottom of the hood assembly 100.

[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. The embodiments of the present application do not make specific requirements thereon.

[0075] In combination with Figure 3 , Figure 4 and Figure 6 In the embodiments of the present application, the smoke collecting cover 110 includes a first cover body 114 and a second cover body 115, the first cover body 114 and the second cover body 115 jointly enclose the smoke collecting cavity 111, the smoke collecting structure 113 is arranged on the second cover body 115 and connected with the second cover body 115, and the second cover body 115 is a planar structure.

[0076] It is easy to understand that the connection of the first cover body 114 and the second cover body 115 arranged in a split manner forms the smoke collecting cavity 111, facilitating the installation of the smoke collecting cover 110. The second cover body 115 is located on the side away from the main body 300 along the Y direction, facilitating the integration of the integrated cooker 10 with the wall during installation, and the overall appearance of the smoke collecting cover 110 is flat. In addition, the second cover body 115 is a planar structure, and the connection of the second cover body 115 and the smoke gathering structure 113 forms a supporting effect, so as to provide good structural stability and strength, and ensure that the entire smoke collecting cover 110 remains stable during operation and is not easily deformed.

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

[0078] In some embodiments, referring to Figure 5 and Figure 6 , the end of the smoke gathering structure 113 away from the second cover body 115 has a connecting portion 1132, the connecting portion 1132 is bent towards the side away from the first cover body 114, and is detachably connected with the smoke blocking plate 120. In this way, the connecting portion 1132 of the smoke gathering structure 113 forms a supporting and connecting effect on the smoke blocking plate 120, so as to stabilize the connection of the smoke blocking plate 120 and the smoke collecting cover 110.

[0079] The head assembly 100 provided by the embodiment of the present application comprises a smoke collecting cover 110 and a smoke blocking plate 120 arranged above the smoke collecting cover 110. The smoke collecting cover 110 has a smoke collecting cavity 111 extending in the vertical direction, and the front side of the smoke blocking plate 120 has an air inlet 121 communicating with the smoke collecting cavity 111. The smoke collecting cavity 111 has a flow guide structure 112 at the position opposite to the air inlet 121. The flow guide structure 112 guides the oil fume entering the air inlet 121, and makes the oil fume quickly and uniformly gather in the smoke collecting cavity 111, and then be discharged through the flue under the action of the negative pressure fan. In this way, the oil fume extraction efficiency and effect of the range hood can be improved under the same power, and the power consumption of the range hood is further reduced. In the process of oil fume flowing, the flow guide structure 112 generates a certain flow resistance to the flow of the oil fume, further reduces the pressure of the oil fume before entering the air inlet 121 of the range hood, reduces the impact of the oil fume on the range hood, improves the stability of the integrated cooker 10, and reduces the working noise of the integrated cooker 10.

[0080] In addition, referring to Figure 7 and Figure 8, the researchers carried out fluid field analysis on the hood assembly 100 without the flow guide structure 112 and the hood assembly 100 provided with the flow guide structure 112, and obtained the following results: under the same conditions, the oil fume amount of the hood assembly 100 in the embodiment of the application is increased, the oil fume suction efficiency is improved, and the performance of the hood assembly 100 is superior to that of the hood assembly 100 without the flow guide structure 112. Meanwhile, through Figure 7 and Figure 8 It can be seen that the oil fume distribution in the smoke collection cavity is more uniform.

[0081] Referring to Figure 9 and Figure 10 , the researchers carried out fluid field analysis on the hood assembly 100 without the smoke gathering structure 113 and the hood assembly 100 provided with the smoke gathering structure 113, and obtained the following results: under the same conditions, the oil fume amount of the hood assembly 100 in the embodiment of the application is increased, the oil fume suction efficiency is improved, and the performance of the hood assembly 100 is superior to that of the hood assembly 100 without the smoke gathering structure 113.

[0082] After measuring the oil fume pressure drop at the air inlet 121 and the bottom of the smoke collection cavity 111, the pressure drop of the hood assembly 100 without the smoke gathering structure 113 is 61.1 Pa, and the pressure drop of the hood assembly 100 in the embodiment of the application is 56.5 Pa. The pressure drop of the hood assembly 100 is reduced, which can reduce the energy consumption of the integrated cooker 10 and improve the overall performance of the integrated cooker 10.

[0083] In addition, the embodiment of the application can also provide an integrated cooker 10 comprising the hood assembly 100 in any of the above embodiments.

[0084] The integrated cooker 10 in the embodiment of the application, since comprising the hood assembly 100 in the above embodiments, can improve the oil fume suction efficiency and effect of the integrated cooker 10.
