[0039] The present embodiment provides an integrated stove, which can improve the convenience of loading, unloading and repairing the fan assembly inside the integrated stove, and improve the sealing performance of the connection between the fan assembly and the casing.

[0040] like Figures 1 to 5 As shown, in this embodiment, the integrated stove includes a housing 1, a gas stove 7, a hood module and a functional module 8. The gas stove 7 is installed on the top of the housing 1 and is used to cook food; the hood module includes a hood head 6 and a fan assembly 3, the hood head 6 is installed on the top of the housing 1 and located at the rear side of the gas stove 7, and the hood head 6 has a smoke inlet 61 and a smoke collecting cavity connected to the smoke inlet 61; the housing 1 is provided with an air duct 43, and an outer wall of the housing 1 is provided with a smoke exhaust port 122 connected to the air duct 43; the fan assembly 3 includes a fan body 31 and an air outlet pipe 32, the fan body 31 is installed in the air duct 43 and the air inlet is connected to the air duct 43, the air outlet of the fan body 31 is sealed and connected to the air outlet pipe 32, and the air outlet pipe 32 passes through the smoke exhaust port 122 in a sealed manner.

[0041] In this embodiment, the integrated stove further includes a seal 2, which is arranged around the smoke outlet 122 and has a conical ring-shaped seal ring portion 21, which is passed through the smoke outlet 122, and the small end of the seal ring portion 21 faces the outside of the housing 1 and the large end faces the inside of the air duct 43. The outer diameter of the air outlet pipe 32 is smaller than the inner diameter of the small end of the seal ring portion 21 and larger than the inner diameter of the large end of the seal ring portion 21, and the air outlet pipe 32 passes through the seal ring portion 21 from the inside to the outside.

[0042] The integrated stove provided in the present embodiment is provided with a seal 2 having a seal ring portion 21 installed at the smoke exhaust port 122, and the seal ring portion 21 is a conical ring structure with a large inner end and a small outer end, so that when the fan assembly 3 is assembled into the air duct 43, the air outlet pipe 32 can pass through the seal ring portion 21 from the inside to the outside. Since the inner diameter of the outer end of the seal ring portion 21 is smaller than the outer diameter of the air outlet pipe 32, when the air outlet pipe 32 passes through the seal ring portion 21, the small end of the seal ring portion 21 can wrap the air outlet pipe 32, so that the air outlet pipe 32 and the housing 1 are sealed at the smoke exhaust port 122, and the fan assembly 3 and the housing 1 are ensured. The assembly seal at the smoke exhaust port 122; at the same time, since the small end of the sealing ring portion 21 can wrap the air outlet pipe 32 when the air outlet pipe 32 passes through the sealing ring portion 21 from the inside to the outside, there is no need for alignment or other operations of the seal 2, which effectively improves the assembly efficiency of the fan assembly 3 on the casing 1; furthermore, since the seal 2 is installed at the smoke exhaust port 122, when the fan assembly 3 is disassembled, the seal 2 will not be removed with the air outlet pipe 32, which can effectively prevent the seal 2 from falling or being lost, and effectively ensure that the fan assembly 3 can be repeatedly disassembled and assembled, thereby improving the convenience of maintenance and cleaning of the fan assembly 3.

[0043] In this embodiment, the range hood 6, the gas stove 7 and the functional module 8 can be set with reference to the prior art, which is not the focus of this embodiment and is not limited or elaborated in this embodiment. Among them, the functional module 8 can be, but not limited to, a steam oven, a dishwasher, a disinfection cabinet, a cabinet, etc.

[0044] like Figures 1 to 3 As shown, the housing 1 has two housing side panels 11 spaced apart in the left and right directions, and the smoke exhaust port 122 is arranged on the housing side panels 11, thereby facilitating the docking convenience between the integrated stove and the public flue, and improving the convenience of installation and use of the integrated stove. In other embodiments, the housing 1 may also be provided with the above-mentioned smoke exhaust port 122 on its housing back panel.

[0045] Smoke outlets 122 are provided on both shell side plates 11, and the seals 2 are provided one-to-one with the smoke outlets 122. The air outlet pipe 32 is provided through the seal 2 on one side, and the integrated stove further comprises a cover 5, which blocks the smoke outlet 122 on the other side. Thus, the installation state of the fan assembly 3 can be selected according to the position of the public flue in the installation environment of the integrated stove, thereby improving the installation flexibility and versatility of the integrated stove, and by providing the cover 5, smoke leakage from the unused smoke outlet 122 can also be avoided.

[0046] Further, the fan assembly 3 has a first installation state and a second installation state. When the fan assembly 3 is in the first installation state, the air outlet duct 32 of the fan assembly 3 is inserted into the seal 2 corresponding to the left smoke exhaust port 122, and the cover 5 blocks the right smoke exhaust port 122. When the fan assembly 3 is in the second installation state, the air outlet duct 32 of the fan assembly 3 is inserted into the seal 2 corresponding to the right smoke exhaust port 122, and the cover 5 blocks the left smoke exhaust port 122.

[0047] like Figures 3 to 6 As shown, in order to improve the convenience of forming the air duct 43, in this embodiment, a bellows 4 is provided inside the housing 1, and an air duct 43 is formed inside the bellows 4, so that the shape of the bellows 4 can be specifically set according to the shape of the air duct 43, so as to better ensure the sealing of the air duct 43. The bellows 4 has an air outlet side plate 41 directly opposite to the smoke exhaust port 122, and a pipe through hole 411 is provided on the air outlet side plate 41. The smoke exhaust port 122 is connected to the air duct 43 through the pipe through hole 411, and the air outlet side plate 41 is sealed and butted with the end face where the smoke exhaust port 122 is located, so as to ensure the sealing of the connection between the air duct 43 and the smoke exhaust port 122.

[0048] In order to improve the sealing convenience between the bellows 4 and the casing 1, in this embodiment, the large end of the sealing ring portion 21 is radially extended outward with a mounting ring portion 22, and the mounting ring portion 22 is clamped between the air outlet side plate 41 and the inner side wall of the casing 1. By providing the mounting ring portion 22, when the integrated stove is assembled, the mounting ring portion 22 is clamped between the casing 1 and the bellows 4, and then the casing 1 and the bellows 4 are fixed, so that the sealing member 2 can be stably installed on the casing 1, reducing the risk of the sealing member 2 falling off; at the same time, the mounting ring portion 22 is clamped between the inner side wall of the casing 1 and the air outlet side plate 41, so that the mounting ring portion 22 can seal the gap between the casing 1 and the air outlet side plate 41, avoid the smoke in the bellows 4 from leaking from the gap at the connection between the bellows 4 and the casing 1, and avoid the additional setting of a sealing structure to seal the connection between the casing 1 and the bellows 4, simplify the sealing structure of the integrated stove at the smoke outlet 122, and reduce costs.

[0049] In other embodiments, other sealing structures may be used to seal between the air outlet side panel 41 and the casing 1. For example, a sealing ring structure is additionally provided between the air outlet side panel 41 and the inner wall of the casing 1, and the pipe through hole 411 and the smoke exhaust port 122 are both located on the inner side of the sealing ring.

[0050] The thickness of the sealing ring portion 21 gradually decreases in the direction away from the mounting ring portion 22, that is, the thickness of the sealing ring portion 21 gradually decreases from the large end to the small end of the sealing ring portion 21, so as to increase the flexibility at the small end of the sealing ring portion 21 while ensuring the overall structural strength of the seal 2, thereby avoiding the setting of the conical ring portion 21 to hinder the air outlet pipe 32 from passing through the sealing ring portion 21, thereby improving the assembly smoothness of the fan assembly 3.

[0051] The thickness of the sealing ring portion 21 at the large end is equal to the thickness of the mounting ring portion 22, so as to improve the processing convenience of the sealing member 2. The thickness of the sealing ring portion 21 at the small end is equal to 60% to 85% of the thickness of the mounting ring portion 22. Further, the wall thickness of the small end of the sealing ring portion 21 is 2 mm to 5 mm, so as to avoid the sealing ring portion 21 being too thick and causing the elasticity to be reduced, thereby affecting the wrapping and sealing of the air outlet pipe 32, and also to avoid the sealing ring portion 21 being too thin and causing the air outlet pipe 32 to be wrapped loosely.

[0052] In order to better ensure the wrapping performance of the small end of the sealing ring portion 21 on the air outlet pipe 32, the difference between the inner diameter of the small end of the sealing ring portion 21 and the diameter of the air outlet pipe 32 is 0.5mm~1.2mm, so as to ensure that the small end of the sealing ring portion 21 is in a state of radially outward tension and deformation when the air outlet pipe 32 passes through, thereby ensuring the tightness of wrapping the air outlet pipe 32 and at the same time not causing major obstacles to the air outlet pipe 32 being inserted into or exiting the sealing ring portion 21.

[0053] Furthermore, in a natural state, the inner wall surface of the sealing ring portion 21 has an inclination angle of 15° to 25° relative to the horizontal plane, so that the axial length of the sealing ring portion 21 is more appropriate. At the same time, when the air outlet pipe 32 passes through the sealing ring portion 21, the sealing ring portion 21 can be squeezed and deformed to increase the contact area between the air outlet pipe 32 and the sealing ring portion 21, thereby further increasing the sealing reliability.

[0054] In order to better guide the air outlet pipe 32 to be inserted into the smoke exhaust port 122, in the present embodiment, the hole wall of the pipe through hole 411 is connected with a guide ring portion 42 along the direction away from the smoke exhaust port 122, that is, the guide ring portion 42 extends toward the inside of the bellows 4, and the inner diameter of the guide ring portion 42 gradually increases along the direction away from the smoke exhaust port 122, thereby making the channel formed by the guide ring portion 42 a bell-mouth structure that gradually increases inward, which is beneficial to guiding the air outlet pipe 32 from the inside to the outside through the sealing ring portion 21, thereby further improving the assembly smoothness of the fan assembly 3.

[0055] The included angle between the guide ring 42 and the air outlet side plate 41 is preferably 30° to 60°. The guide ring 42 and the air outlet side plate 41 are preferably connected by a circular arc smooth transition to avoid scratches on the air outlet pipe 32 caused by the edges.

[0056] In this embodiment, the bellows 4 includes a longitudinal box portion and a transverse box portion, the longitudinal box portion is vertical and located at the rear side of the functional module 8, and the transverse box portion is transversely arranged below the functional module 8. A longitudinal air duct is formed inside the longitudinal box portion, and a transverse air duct is formed inside the transverse box portion. The upper end of the longitudinal air duct is connected to the smoke collecting chamber, and the lower end of the longitudinal air duct is connected to the transverse air duct. The fan assembly 3 is installed in the transverse air duct, and the rotating shaft of the fan body 31 is arranged vertically. That is, in the embodiment, the bellows 4 is arranged in an L-shaped manner, the air duct 43 in the bellows 4 is an L-shaped air duct 43, and the fan body 31 is arranged horizontally in the transverse air duct, thereby reducing the occupation of the fan assembly 3 to the rear space of the functional module 8, thereby reducing the size of the integrated stove in the front-to-back direction, improving the compactness of the structure of the integrated stove, or on the basis of the unchanged size of the integrated stove in the front-to-back direction, increasing the size of the functional module 8 in the front-to-back direction, and improving the design flexibility of the functional module 8; at the same time, the fan assembly 3 is installed in the transverse air duct, which is more conducive to the loading and unloading of the fan assembly 3.

[0057] In other embodiments, the wind box 4 may also mainly include a longitudinal box portion, and the fan assembly 3 is disposed in the longitudinal box portion and the rotating shaft of the fan assembly 3 is disposed along the front-to-back direction.

[0058] like Figure 2 , Figure 7 and Figure 8As shown, in this embodiment, each shell side plate 11 is inwardly recessed to form a mounting recess 12, and the recessed area of ​​the mounting recess 12 forms a groove 121. The bottom of the groove 121 is provided with a smoke exhaust port 122, and the small ends of the cover 5 and the seal 2 are both arranged inside the groove 121. The arrangement of the mounting recess 12 can hide the cover 5, the seal 2, and the connection structure between the fan assembly 3 and the shell 1, thereby improving the appearance of the integrated stove, and at the same time, it can also prevent the cover 5 or the connection structure from protruding from the shell side plate 11 and affecting the installation of the integrated stove.

[0059] In order to improve the convenience of installation and disassembly of the cover 5, the cover 5 is interference-fitted on the outer side of the sealing ring part 21 from the outside to the inside to close the smoke exhaust port 122, so that the cooperation between the mounting ring part 22 and the cover 5 can not only realize the stable installation of the cover 5 in the mounting recess 12, but also realize the sealing between the cover 5 and the sealing ring part 21 through the interference fit between the sealing ring part 21 and the cover 5, thereby realizing the closure of the smoke exhaust port 122 by the cover 5, and effectively simplifying the installation structure of the cover 5.

[0060] Specifically, the cover 5 includes a cover plate portion 51 and a connecting ring portion 52 obliquely connected to the outer periphery of the cover plate portion 51 . The connecting ring portion 52 is interference fit on the outer side of the sealing ring portion 21 . The cover plate portion 51 is located on the side of the sealing ring portion 21 away from the bellows 4 .

[0061] Furthermore, in the natural state, in the longitudinal section, the inclination angle of the outer side surface of the sealing ring portion 21 relative to the horizontal plane is α1, and the inclination angle of the connecting ring portion 52 relative to the horizontal plane is α2, and α1<α2. This arrangement allows the sealing ring portion 21 to be squeezed inward when the connecting ring portion 52 is sleeved on the sealing ring portion 21, so that the sealing ring portion 21 is deformed, so that the outer side wall of the sealing ring portion 21 can fit closely to the inner side wall of the connecting ring portion 52, thereby ensuring that the cover 5 is stably installed on the sealing ring portion 21 and enhancing the sealing between the sealing ring portion 21 and the connecting ring portion 52. Furthermore, 0°<α2-α1≤5°, so as to avoid excessive deformation of the sealing ring portion 21 and damage to the sealing ring portion 21.

[0062] In order to further improve the installation stability and assembly efficiency of the cover 5, the cover 5 further includes an outer ring portion 53, which is connected to the outer periphery of the connecting ring portion 52 and is parallel to and spaced from the cover portion 51. The outer ring portion 53 abuts against the bottom of the groove 121 to provide positioning for the installation of the cover 5. That is, in this embodiment, the length of the outer wall of the sealing ring portion 21 in the axial direction of the air outlet pipe 32 is less than or equal to the spacing between the outer ring portion 53 and the cover portion 51, so as to ensure that the outer ring portion 53 can fit with the groove 121 and avoid the sealing ring portion 21 abutting against the cover portion 51 to affect the installation of the cover 5.

[0063] In order to ensure the installation stability of the cover 5, the outer ring portion 53 is detachably connected to the housing 1 to prevent the cover 5 from falling under vibration or external force, thereby ensuring the reliability of the cover 5. Specifically, the outer ring portion 53 is connected to the bottom of the groove 121 by fastening screws, and at least two fastening screws are arranged at intervals along the circumference of the outer ring portion 53 to ensure the installation reliability of the cover 5.

[0064] Furthermore, the outer ring portion 53 partially extends outward with a fixing ear portion 54, and a plurality of fixing ears 54 are arranged at intervals along the circumference of the outer ring portion 53. A fixing hole is arranged at the connection between the fixing ear portion 54 and the outer ring portion 53, and the fixing hole corresponds to a fastening screw one by one. The fastening screw passes through the fixing hole and is fastened to the housing 1. The provision of the fixing ear portion 54 can increase the size of the fixing hole while reducing the width of the outer ring portion 53, thereby increasing the size of the fastening screw, and ensuring the installation firmness of the cover 5.
