[0002] An integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, gas stove, steam oven, disinfection cabinet, and storage cabinet.

[0003] In an existing technology regarding an integrated stove, a range hood assembly is provided in the lower machine of the integrated stove, and the two upper smoke hoods of the integrated stove are simultaneously connected to the range hood assembly through pipes, so that the oil smoke of the two smoke hoods is discharged together by the range hood assembly. However, the range hood assembly can only match one connection method. If the layout positions of the two smoke hoods on the integrated stove change, it can only be done by replacing the air duct pipe connecting the smoke hood and the range hood assembly, resulting in poor space optimization. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a range hood assembly and an integrated stove, which can match different connection modes and air inlet positions and have better adaptability.

[0005] The utility model is realized through the following technical solutions.

[0006] A range hood assembly includes an outer shell and a volute fan arranged in the outer shell, the outer shell having multiple air inlet surfaces provided with air inlets, and suction surfaces formed on both sides of the volute fan, one of the suction surfaces facing at least one of the air inlet surfaces, and the other suction surface facing at least two of the air inlet surfaces.

[0007] As a further improvement of the present invention, the air inlet of the air inlet surface is used to connect to the air duct pipe, and the air inlet not connected to the air duct pipe is provided with a sealing plate.

[0008] As a further improvement of the present invention, the air inlet surface of the volute fan is formed to be convex outward, and air inlet holes are provided on the air inlet surface.

[0009] As a further improvement of the present invention, mounting seats are provided on both sides of the volute blower, and brackets for supporting the mounting seats are provided in the outer shell.

[0010] As a further improvement of the present invention, the outer shell is rectangular, and two sides of the volute fan correspond to the corners of the outer shell respectively.

[0011] An integrated stove comprises a lower range hood module equipped with the range hood assembly, two lower functional modules connected to the lower range hood module, and two upper smoke collection modules respectively located above the corresponding lower functional modules. The two upper smoke collection modules and the two air inlet surfaces of the range hood assembly are connected to air duct pipes for discharging oil smoke into the range hood assembly.

[0012] As a further improvement of the present invention, the lower range hood module has at least three first assembly parts, the lower functional module has a second assembly part, and the second assembly parts of two lower functional modules are connected to any two first assembly parts of the lower range hood module.

[0013] As a further improvement of the present invention, the first assembly part and the second assembly part are detachably connected.

[0014] As a further improvement of the present invention, the second assembly parts of the two lower functional modules are respectively connected to the two opposite first assembly parts of the lower range hood module.

[0015] As a further improvement of the present invention, the second assembly parts of the two lower functional modules are respectively connected to the two adjacent first assembly parts of the lower range hood module.

[0016] Beneficial effects of the utility model:

[0017] 1. The volute fan is set with double suction surfaces, which increases the smoking range. One suction surface faces at least one air inlet surface, and the other suction surface faces at least two air inlet surfaces. It can match different connection methods and air inlet positions and has better adaptability.

[0018] 2. Since the air inlet corresponding to the suction surface is different depending on the connection, the flow direction of the oil smoke after entering the bellows is also different. Setting it in an outward convex shape can better allow the oil smoke to enter the volute fan, improving the exhaust efficiency. At the same time, compared with a flat surface, it can also increase the area of ​​the air inlet surface, thereby increasing the area of ​​the volute fan to absorb oil smoke, thereby further improving the exhaust efficiency.

[0019] 3. The air inlet that is not connected to the air duct is blocked by a sealing plate to avoid leakage of oil smoke and facilitate operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0029] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0030] An integrated stove, referring to Figure 1-7 , including a lower range hood module 1, two lower functional modules 2, two upper smoke collection modules 3, and a stove plate 4. The two upper smoke collection modules 3 are located above the stove plate 4, and the lower range hood module 1 and the two lower functional modules 2 are located below the stove plate 4. More specifically, the two lower functional modules 2 are connected to the lower range hood module 1, forming a complete lower unit of the integrated stove. The two upper smoke collection modules 3 correspond to the two lower functional modules 2 respectively. The two upper smoke collection modules 3 and the lower range hood module 1 are both connected to an air duct 31. The upper smoke collection modules 3 absorb the fumes generated by cooking, and the fumes entering the upper smoke collection modules 3 are discharged to the lower range hood module 1 through the air duct 31.

[0031] In this embodiment, by separating the lower range hood module 1 and the lower functional module 2 from the lower machine as a whole, on the one hand, the volume occupied by the two lower functional modules 2 can be maximized, and the lower functional module 2 that occupies sufficient space can have better performance and configuration, such as being able to be configured with larger models and more functional ovens, dishwashers, etc.; on the other hand, the volume occupied by the lower range hood module 1 can also be maximized, thereby having better oil fume suction performance, such as being configured with a more powerful range hood component 12.

[0032] In this embodiment, the lower range hood module 1 has at least three first assembly portions 1a, and the lower functional module 2 has one second assembly portion 2a. The second assembly portions 2a of two lower range hood modules 1 connect to any two first assembly portions 1a of the lower range hood module 1. Therefore, in this embodiment, because the lower range hood module 1 has multiple different first assembly portions 1a for connecting to the second assembly portions 2a of the lower functional modules 2, the lower unit of the integrated stove can be configured in a variety of structural shapes to suit different kitchen layouts.

[0033] In this embodiment, the first assembly portion 1a and the second assembly portion 2a are detachably connected. The two upper smoke collection modules 3 have the same structure, and the two lower functional modules 2 have the same structure. Due to the detachable connection between the first assembly portion 1a and the second assembly portion 2a, the overall modularity of the lower unit is higher, which has greater advantages in production costs. At the same time, the highly modular structure also facilitates transportation and saves logistics costs.

[0034] For the connection method of lower range hood module 1 and lower function module 2, refer to Figure 3 In one embodiment, the second assembly parts 2a of the two lower functional modules 2 are respectively connected to the two first assembly parts 1a opposite to the lower range hood module 1, so that the integrated stove presents a straight-line structure, which is particularly suitable for kitchen spaces with a narrow width but a long length.

[0035] For the connection method of lower range hood module 1 and lower function module 2, refer to Figure 4 In another embodiment, the second assembly parts 2a of the two lower functional modules 2 are respectively connected to the two adjacent first assembly parts 1a of the lower range hood module 1, so that the integrated stove presents a corner structure, which is particularly suitable for kitchen spaces with a wider width. It can be set at the corner of the kitchen and can leave more space for other kitchen equipment such as refrigerators.

[0036] In this embodiment, the lower range hood module 1 includes a first lower frame 11, which is used to set the range hood assembly 12. The lower functional module 2 includes a second lower frame 21, which is used to set kitchen functional equipment 22, such as an oven, a steamer, a dishwasher, a disinfection cabinet, a storage cabinet, and other kitchen functional configurations. Among them, the side of the first lower frame 11 forms a first assembly part 1a, and the side of the second lower frame 21 forms a second assembly part 2a. The detachable connection between the first assembly part 1a and the second assembly part 2a corresponds to the detachable connection between the sides of the first lower frame 11 and the second lower frame 21. Specifically, a detachable connection structure can be set at the frame edge or frame corner, which not only facilitates connection and disassembly operations, but also has good connection firmness and stability.

[0037] In this embodiment, more specifically, the range hood assembly 12 includes a bellows 121 and a volute fan 122. The volute fan 122 is arranged in the bellows 121. The bellows 121 has multiple sides, and the bellows 121 is provided with an air inlet 1211 on the side corresponding to the first assembly part 1a in the lower range hood module 1. The side of the bellows 121 with the air inlet 1211 forms an air inlet surface, that is, the bellows 121 has at least three air inlet surfaces. Suction surfaces 1221 are formed on both sides of the volute fan 122. The setting position and setting angle of the volute fan 122 in the air box 121 make one of the suction surfaces 1221 of the volute fan 122 face at least one air inlet surface, and the other suction surface 1221 faces the other air inlet surface. That is to say, after any two first assembly parts 1a in the lower range hood module 1 and the second assembly surface of the lower functional module 2 are connected, the oil smoke that enters the air box 121 through the air duct pipe 31 can correspond to the suction surface 1221, so that the oil smoke can be quickly sucked into the volute fan 122, so that the range hood assembly 12 has efficient oil smoke exhaust performance while having high connection and installation adaptability.

[0038] In this embodiment, the air duct pipe 31 is located in the upper space of the second lower frame 21 and is close to the side of the second lower frame 21. The air inlet 1211 is arranged on the upper side of the bellows 121. By optimizing the position of the air inlet 1211, the space occupied by the air duct pipe 31 in the second lower frame 21 is minimized, thereby reducing the impact on the installation and setting of the kitchen functional equipment 22 in the second lower frame 21.

[0039] More specifically, in this embodiment, the air box 121 is rectangular, with air inlets 1211 disposed on three sides thereof, corresponding to two connection arrangements: the second assembly portions 2a of the two lower functional modules 2 are connected to the two opposing first assembly portions 1a of the lower range hood module 1, and the second assembly portions 2a of the two lower functional modules 2 are connected to the two adjacent first assembly portions 1a of the lower range hood module 1. The two sides of the volute fan 122 correspond to the corners of the air box 121, allowing one air inlet surface of the volute fan 122 to face one air inlet 1211, and the other air inlet surface to face both air inlets 1211.

[0040] In this embodiment, the air inlet 1211 corresponding to the first assembly portion 1a connected to the second assembly portion 2a is connected to the air duct 31, and the air inlet 1211 corresponding to the first assembly portion 1a not connected to the second assembly portion 2a is provided with a sealing plate 1212. The sealing plate 1212 blocks the air inlet 1211 not connected to the air duct 31, preventing oil smoke leakage and facilitating operation.

[0041] In this embodiment, the suction surface 1221 of the volute fan 122 is formed to be convex outward, and air inlet holes are provided on the suction surface 1221. The air inlet holes can be set into a honeycomb structure to improve the structural strength and stability of the suction surface 1221, so that the suction surface 1221 is formed into a structure that is convex outward and is less prone to aging and deformation. Since the suction surface 1221 corresponds to different air inlets 1211 depending on the connection, the flow direction of the oil smoke after entering the bellows 121 is also different. Setting it to an outward convex shape can better allow the oil smoke to enter the volute fan 122, improving the smoke exhaust efficiency. At the same time, it can also increase the area of ​​the air inlet surface compared to a flat surface, thereby increasing the area of ​​the volute fan 122 that absorbs oil smoke, thereby further improving the smoke exhaust efficiency. The specific structural shape of the suction surface 1221 is preferably an outward convex spherical surface or an arc surface.

[0042] In this embodiment, mounting seats 1223 are provided on both sides of the volute fan 122, and a bracket 1213 for supporting the mounting seats 1223 is provided in the bellows 121 to facilitate the installation of the volute fan 122. In addition, in order to improve the stability of the volute fan 122 in the bellows 121, the mounting seat 1223 and the bracket 1213 can be connected by fasteners.

[0043] In this embodiment, a smoke exhaust pipe 1214 is connected to the bottom of the bellows 121 , and the smoke exhaust pipe 1214 discharges the oil smoke sucked in by the volute blower 122 .

[0044] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
