[0056] The present application will be further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended for the purpose of interpretation of the present application and are not limiting of the present application. In addition, it should be noted that, for the purpose of description, only the parts related to the present application are shown in the drawings and not all the structures.

[0057] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements.

[0058] In the present application, unless otherwise explicitly specified and limited, the "upper" or "lower" of the first feature to the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the "upper", "above" and "on" of the first feature to the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The "below", "under" and "under" of the first feature to the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0059] In the description of the present embodiment, the terms "upper", "lower", "left", "right" and other orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used to distinguish in the description, and have no special meaning.

[0060] The present embodiment provides an air outlet structure of an integrated stove, which can change the direction of the air outlet pipe 27 without increasing parts, and the air outlet structure of the integrated stove is more flexible to install. As shown in Figure 1 and Figure 2As shown, the air outlet structure of the integrated stove includes a frame mechanism 10, a negative pressure mechanism 20, and a flue assembly 30. The frame mechanism 10 includes a frame assembly 11 and an air outlet protective cover 12. The upper and front sides of the frame assembly 11 are open, and mounting holes 111 are provided on both the left and right sides of the frame assembly 11. The air outlet protective cover 12 can be selectively installed in one of the two mounting holes 111. The negative pressure mechanism 20 is installed inside the frame assembly 11. The negative pressure mechanism 20 includes a housing 21, a wind drive assembly 22, a sealing plate 26, and an air outlet duct 27. The left and right sides of the housing 21... Each side has an adapter 211. The sealing plate 26 and the air outlet 27 can be interchangeably installed on the two adapters 211. The air outlet 27 is connected to the external exhaust pipe through the mounting hole 111 on the corresponding side. The wind drive assembly 22 is located inside the housing 21 and can generate negative pressure. The air outlet 2212 of the wind drive assembly 22 can be selectively connected to one of the two adapters 211. An air inlet 213 is opened on the rear side of the housing 21. The flue assembly 30 is located on the rear side of the frame assembly 11 and has a flue outlet 31 at its lower end. The air inlet 213 is connected to the flue outlet 31.

[0061] The air outlet structure of the aforementioned integrated stove has mounting holes 111 on both sides of the frame assembly 11. The air outlet protective cover 12 can be selectively installed in one of the two mounting holes 111, and the other mounting hole 111 serves as a connection hole to the external exhaust duct. In the negative pressure mechanism 20, adapter interfaces 211 are provided on both sides of the housing 21. The sealing plate 26 and the air outlet pipe 27 can be interchangeably installed in the two adapter interfaces 211. The air outlet pipe 27 is connected to the external exhaust duct through the mounting hole 111 on the corresponding side. The air outlet 22 of the wind drive assembly 22... 12 can selectively connect to one of the two adapters 211. When the position of the external exhaust duct changes, the air outlet protective cover 12 is moved to the other air outlet 2212, the positions of the air outlet pipe 27 and the sealing plate 26 are swapped, and the air outlet 2212 of the wind drive assembly 22 is connected to the other adapter 211. This allows the air outlet direction of the integrated stove to be changed without the need for spare parts. It is easy to operate and flexible to install. Moreover, when the product leaves the factory, there is no need to know the location of the customer's external exhaust duct, which provides convenience for customers to purchase the product.

[0062] Preferably, such as Figure 1 As shown, the two mounting holes 111 are symmetrically arranged in the left and right directions of the rack assembly 11, and the two adapters 211 are symmetrically arranged on both sides of the housing 21. This symmetrical arrangement improves the aesthetics of the appearance and facilitates the switching of the air outlet protective cover 12 between the two mounting holes 111. Furthermore, the fan drive assembly 22 is rotated 180°, with the rotation center aligned with the left and right symmetrical lines of the housing 21. After rotation, the symmetrical arrangement makes it easier to realign the air outlet 2212.

[0063] Since the air outlet 2212 needs to be communicated with the corresponding mounting hole 111, and the mounting hole 111 on the other side needs to be connected with the air outlet protective cover 12, since the air outlet protective cover 12 is flat, the installation can be realized by setting a step at the mounting hole 111, but since the air outlet pipe 27 has a certain length and its axis is set at an angle with the mounting hole 111, the same setting cannot better realize the connection strength of the air outlet pipe 27 and the mounting hole 111.

[0064] In order to solve the above problems, as shown in Figure 1 The rack mechanism 10 also includes an air outlet protective ring 13, which is selectively installed on any mounting hole 111, and the air outlet pipe 27 is connected with the air outlet protective ring 13. Through the above setting, the air outlet protective ring 13 improves the connection strength with the air outlet pipe 27, and at the same time ensures the consistency of the left and right side plates of the rack assembly 11.

[0065] Specifically, the air outlet protective ring 13 includes a ring-shaped elongated portion 132 and a flange portion 131, which are coaxially arranged and the flange portion 131 is formed by extending the edge of one end of the ring-shaped elongated portion 132 outward, the flange portion 131 is installed on the stepped surface of the mounting hole 111, and the ring-shaped elongated portion 132 is adapted to the inner diameter of the mounting hole 111 to extend into the mounting hole 111, and one end of the air outlet pipe 27 extends into the ring-shaped elongated portion 132 and is fixed. The above setting makes the connection of the air outlet pipe 27 depend on the air outlet protective ring 13, and the setting of the ring-shaped elongated portion 132 increases the connection strength and the range of the connection surface of the air outlet pipe 27, making the connection of the air outlet pipe 27 more convenient, and at the same time allowing the air outlet pipe 27 to have a certain deviation in the length direction.

[0066] Preferably, as shown in Figure 1 The air outlet protective ring 13 also includes a limiting portion 133, which is formed by extending the edge of one end of the ring-shaped elongated portion 132 away from the flange portion 131 inward, and a plurality of limiting protrusions 271 are protruded on the outer periphery of one end of the air outlet pipe 27, when installed, one end of the air outlet pipe 27 is inserted into the limiting portion 133 by its own deformation, the limiting portion 133 can limit the plurality of limiting protrusions 271, and then limit one end of the air outlet pipe 27.

[0067] Preferably, as shown in Figure 2 The negative pressure mechanism 20 also includes a sealing member 23, which is arranged between the sealing plate 26 and the box body 21, and between the air outlet pipe 27 and the box body 21, to ensure the sealing of the inside of the box body 21 when the air-driven assembly 22 operates to generate negative pressure, and to ensure that the negative pressure of the flue gas in the flue gas suction assembly 30 is sufficient.

[0068] Preferably, as shown in Figure 2As shown, the negative pressure mechanism 20 further comprises a clamping member 24, which is L-shaped in cross section. One of the two bent portions of the clamping member 24 abuts against one end of the air outlet pipe 27 connected to the box 21, and the other bent portion of the clamping member 24 protects the outer edge of the mounting end of the air outlet pipe 27 and the sealing member 23. On the one hand, the connection strength of the air outlet pipe 27 and the box 21 is improved, and when a fixing member 82 such as a screw is used for mounting, the fixing member 82 abuts against the clamping member 24, thereby avoiding abrasion and damage to the air outlet pipe 27. On the other hand, the plurality of clamping members 24 form a surrounding shape on the sealing member 23 and the one end of the air outlet pipe 27 connected to the box 21, thereby better protecting the sealing member 23 and the air outlet pipe 27.

[0069] In this embodiment, the one end of the air outlet pipe 27 connected to the box 21 is rectangular, and the four clamping members 24 are integrally formed in a ring shape. In other embodiments, the one end of the air outlet pipe 27 connected to the box 21 can also be circular or polygonal.

[0070] Optionally, as shown in Figure 2 , Figure 3 and Figure 4 , the air driving assembly 22 comprises a volute 221, a motor 222, an impeller 223, and a bracket connecting member 224. The volute 221 forms the air outlet 2212. The motor 222 is mounted inside the volute 221. The impeller 223 is mounted inside the volute 221 and coaxially connected to the motor 222. The motor 222 can drive the impeller 223 to rotate to form a negative pressure inside the volute 221. The bracket connecting member 224 is mounted on the upper and lower sides of the volute 221. Two volute connecting members 212 are mounted on the bottom of the box 21. The volute 221 can be flipped by 180° so that the bracket connecting member 224 can be mounted on the corresponding volute 221 connecting plate. Through the above arrangement, the motor 222 drives the impeller 223 to rotate to discharge gas from the air outlet 2212 to form a negative pressure in the box 21. When it is necessary to change the air outlet direction, the air driving assembly 22 is flipped by 180°, and the volute 221 is still fixed by the volute 221 connecting plate.

[0071] Optionally, as shown in Figure 3 , the air driving assembly 22 further comprises a wind guide ring 225 and a locking nut 226. The wind guide ring 225 is fixedly connected to the volute 221, and the locking nut 226 is coaxially accommodated in the inner cavity of the volute 221. The arrangement of the wind guide ring 225 and the locking nut 226 is common in the prior art, and will not be described here.

[0072] Preferably, as shown in Figure 2As shown, the negative pressure mechanism 20 further comprises an intermediate connecting piece 25, and the air outlet 2212 is connected to the side wall of the box body 21 through the intermediate connecting piece 25. The above arrangement can prevent the direct connection between the outer wall of the air outlet 2212 and the side wall of the box body 21, prevent the deformation of the side wall of the box body 21 during installation, and ensure the uniformity of the outer shape of the left and right side walls of the box body 21.

[0073] Preferably, as Figures 2-4 As shown, the bracket connecting piece 224 is in the form of a groove with the groove opening facing away from the volute 221, and the volute connecting piece 212 is adapted to the outer shape of the groove opening. That is, the groove wall of the bracket connecting piece 224 plays a guiding and limiting role when it is installed on the volute connecting piece 212, so that when the two are connected, the groove wall assists in positioning in addition to the fasteners, reducing the connection load of the fasteners and improving the connection strength of the two.

[0074] Preferably, the bracket connecting piece 224 is installed at the farthest end from the air outlet 2212. Through the above arrangement, one of the two support points of the volute 221 is the connection between the air outlet 2212 and the box body 21, and the other is the bracket connecting piece 224. The distance between the two is the farthest, which ensures that when the volute 221 is supported, the two support points are located at two far points, thereby ensuring the stability of the volute 221 being supported, making the connection of the air driving assembly 22 more firm and reliable, and being able to reduce the vibration of the air driving assembly 22 and reduce the operating noise.

[0075] Preferably, as Figures 2-4 As shown, at least two auxiliary holes 2241 are formed on the bracket connecting piece 224 along the length direction thereof, the at least two auxiliary holes 2241 are arranged in a straight line, auxiliary protrusions 2211 are outwardly protruded on the upper and lower sides of the volute 221, the auxiliary protrusions 2211 are arranged in one-to-one correspondence with the auxiliary holes 2241, and the connecting line of the at least two auxiliary holes 2241 intersects with the axis of the volute 221. Through the above arrangement, when the auxiliary protrusions 2211 of the volute 221 are protruded, the projection point of the axis of the volute 221 in the horizontal direction is identified first during programming, and then a point for protruding an auxiliary protrusion 2211 is found at the farthest point from the air outlet 2212. After the two are connected into a straight line, the positions of the remaining auxiliary protrusions 2211 can be quickly found on the straight line for setting, facilitating the setting of the auxiliary protrusions 2211. After the auxiliary protrusions 2211 and the auxiliary holes 2241 are set, the bracket connecting piece 224 can be installed relatively quickly. In the present embodiment, the auxiliary protrusions 2211 and the auxiliary holes 2241 are connected by welding after installation. In other embodiments, the two can be connected by riveting or other connection methods after positioning, which is not limited herein.

[0076] Preferably, as Figure 4As shown, the bottom plate of the box body 21 is inclined to the center to make the oil stains flow down from below, and a horizontal mounting platform 216 is upwardly protruded on the bottom plate of the box body 21 for facilitating the installation of the volute connecting piece 212. The mounting platform 216 is provided with mounting protrusions 217, and the limiting holes on the volute connecting piece 212 are welded to the mounting protrusions 217. Through the above arrangement, a stable mounting plane is provided for the installation of the volute connecting piece 212, and the mounting protrusions 217 can facilitate the quick positioning of the volute connecting piece 212.

[0077] Preferably, the holes for screwing on the support connecting piece 224 are waist-shaped holes, which can provide a certain amount of fine adjustment for the installation of the support connecting piece 224.

[0078] Preferably, as shown in Figure 1 and Figure 5 , the rack mechanism 10 further comprises a bracket assembly 14, which comprises a bracket body 141 and a slide rail 142. The bracket body 141 is installed on the lower side of the rack assembly 11, and the slide rail 142 extends in the front-rear direction and is installed on the bracket body 141. The box body 21 is in sliding cooperation with the slide rail 142. Through the above arrangement, when the negative pressure mechanism 20 is installed, it can be installed along the slide rail 142, which is accurate and convenient and fast. It can be understood that, as shown in Figure 1 and Figure 6 , after the box body 21 is installed along the slide rail 142, the air inlet 213 and the flue outlet 31 can be accurately matched.

[0079] Preferably, a sealing strip (not labeled) is arranged between the air inlet 213 and the flue outlet 31 to ensure the sealing performance.

[0080] Preferably, as shown in Figure 4 and Figure 5 , the slide rail 142 is inverted in the shape of a few characters, and the lower side of the box body 21 is provided with a box lower slide rail 215 arranged in the shape of Z. The vertical surface of the box lower slide rail 215 can slide along the vertical surface of the slide rail 142, and the two form a limit to prevent the box body 21 from moving in the left-right direction.

[0081] Preferably, as shown in Figure 1 and Figure 6 , the air outlet structure of the integrated cooker further comprises a negative pressure box limiting plate 70, which is installed on the front side of the bracket body 141 and abuts against the front side of the box body 21. Through the above arrangement, the front and rear sides of the box body 21 are limited, and from then on, the front, rear, left and right sides of the box body 21 are stably limited, which ensures the installation stability of the box body 21 and the entire negative pressure mechanism 20, and plays a role in overall shock absorption.

[0082] Preferably, as shown in Figure 1 , Figure 5 andFigure 6 As shown, the bracket body 141 is provided with an oil cup accommodating groove 1411, and the air outlet structure of the integrated cooker further comprises an oil cup 40, and the liquid collected in the negative pressure mechanism 20 and the flue assembly 30 can all fall into the oil cup 40. That is, even if the direction of the air duct changes, the oil cup 40 will not be affected in collecting oil. The negative pressure box limiting plate 70 is arranged to avoid the oil cup 40.

[0083] Specifically, as shown in Figure 1 Figure 5 and Figure 6 , the lower side of the flue assembly 30 is provided with a first through hole 32, and the air outlet structure of the integrated cooker further comprises an oil collecting assembly 80, which is installed on the rack assembly 11 and below the first through hole 32. The oil collecting assembly 81 has a first inclined surface recessed to the middle, and a second through hole 811 is formed at the lowest part of the first inclined surface. The oil cup 40 is installed on the rack assembly 11 and below the oil collecting assembly 80, and the second through hole 811 is arranged opposite to the oil cup 40. The air outlet structure of the integrated cooker described above is arranged by providing the first through hole 32 on the lower side of the flue assembly 30, and arranging the oil collecting assembly 80 below the first through hole 32. The oil collecting assembly 80 has a first inclined surface recessed to the middle, and a second through hole 811 is formed at the lowest part of the first inclined surface. The second through hole 811 is opposite to the oil cup 40. In this way, the oil stains of the flue assembly 30 can flow onto the oil collecting assembly 80 and then flow into the oil cup 40 along the first inclined surface and through the second through hole 811, so as to avoid the accumulation of oil stains in the flue assembly 30.

[0084] Preferably, as shown in Figure 1 , Figures 5-7 , the bracket assembly 14 further comprises an oil cup support 143, which is installed in the accommodating groove and used to support the oil cup 40. Through the above arrangement, the oil cup 40 is well supported by the oil cup support 143 when installed.

[0085] Preferably, as shown in Figure 6 and Figure 7 , the oil cup support 143 comprises a body 1431 and at least three bent portions 1432. The body 1431 is in the shape of a groove, and at least part of the oil cup 40 is accommodated in the body 1431. The bent portions 1432 are in the shape of L, and the vertical edges of the bent portions 1432 are connected to the body 1431, and the horizontal edges of the bent portions 1432 are connected to the bottom plate of the rack assembly 11. The part of the body 1431 above the horizontal edges of the bent portions 1432 is provided with an avoiding hole 14311. Through the above arrangement, the three bent portions 1432 are all downward, which can avoid the deformation or rupture of the oil cup 40 caused by the force transmitted from other components. In addition, the groove bottom and sidewall of the body 1431, as well as other supporting or guiding parts, are not in contact with the connecting members such as screws, so that the oil cup 40 can be more smoothly plugged and unplugged, and will not be damaged.

[0086] Optionally, such as Figure 1 , Figure 5 and Figure 6 As shown, the oil collecting assembly 80 includes a fixing member 82 and an oil collecting trough 81. The fixing member 82 is L-shaped and one side is mounted on the bracket assembly 14 (more specifically, on the bracket body 141). The bottom surface of the oil collecting trough 81 is mounted on the bracket assembly 14, and the other side of the fixing member 82 is fixedly connected to one side of the oil collecting trough 81. An installation notch 1413 is provided on the bracket assembly 14 (more specifically, the bracket body 141). Figure 2 The first inclined surface and the second through hole 811 coincide (not labeled). Both the first inclined surface and the second through hole 811 are provided in the oil collecting groove 81 and have an installation notch 1413. The second through hole 811 extends toward the oil cup 40. Through the above arrangement, the oil collecting groove 81 is well supported by the bracket body 141 and well fixed by the fastener 82. The second through hole 811 extends downward, which allows the second through hole 811 to be closer to the oil cup 40, preventing oil splashing. The fastener 82 is welded to the oil collecting groove 81, and the fastener 82 can be connected to the bracket assembly 14 by screws.

[0087] Furthermore, such as Figure 2 and Figure 6 As shown, the bottom surface of the housing 21 forms a second inclined surface, and a third through hole 214 is opened at the lowest point of the second inclined surface. A fourth through hole 1412 is opened on the bracket assembly 14 (more specifically, the bracket body 141). Both the third through hole 214 and the fourth through hole 1412 are directly opposite the oil cup 40. Oil can flow out from the volute oil drain hole 2213, pass through the second inclined surface, and fall into the oil cup 40 through the third through hole 214 and the fourth through hole 1412. With the above arrangement, the volute oil drain hole 2213 is provided on the wind drive assembly 22. The oil sludge formed inside the wind drive assembly 22 flows through the volute oil drain hole 2213, flows to the second inclined surface, collects in the third through hole 214, and then falls into the oil cup 40 through the fourth through hole 1412. From this point on, the oil sludge in the negative pressure mechanism 20 and the flue assembly 30 can flow into the oil cup 40. One oil cup 40 collects all the oil sludge, making it easier to clean the oil sludge.

[0088] Preferably, such as Figure 1 As shown, the air outlet structure of the integrated stove also includes an access door 60 and a rebound assembly 90. The rebound assembly 90 is installed on the front side of the frame assembly 11, and the access door 60 is pivotally connected to the frame assembly 11. Through the above arrangement, the opening and closing of the internal space of the frame assembly 11 can be achieved relatively easily. The structure of the rebound assembly 90 is quite common in the prior art and will not be described in detail here.

[0089] Optionally, such as Figure 1 and Figure 6As shown, the air outlet structure of the integrated cooker further comprises a toe kick plate 50 which is connected to the front end of the bottom of the left and right side surfaces of the rack assembly 11 in a plug-in manner, and the middle part of the toe kick plate 50 is provided with an oil cup socket 51 which is matched with the oil cup 40. The plug-in connection between the toe kick plate 50 and the rack assembly 11 makes it more convenient to disassemble and assemble.

[0090] The embodiment also provides a method for changing the air outlet direction of the integrated cooker, which is used for changing the air outlet direction of the air outlet structure of the integrated cooker, and comprises the following steps:

[0091] S10: dismounting the air outlet pipe 27 from the corresponding mounting hole 111 and dismounting the air outlet protective cover 12 from the corresponding mounting hole 111;

[0092] S20: dismounting the negative pressure mechanism 20 and pulling out the box body 21 along the slide rail 142;

[0094] S40: mounting the sealing plate 26 and the air outlet pipe 27 to the corresponding adapter 211 in a position changing manner;

[0095] S50: mounting the air outlet protective cover 12 to the other air outlet 2212;

[0096] S60: mounting the reorganized negative pressure mechanism 20 to the bracket assembly 14 again and connecting the air outlet pipe 27 with the other mounting hole 111.

[0097] The method for changing the air outlet direction of the integrated cooker adjusts the air outlet direction of the air outlet structure of the integrated cooker, and the air outlet direction of the integrated cooker can be changed by changing the air outlet protective cover 12 to the other air outlet 2212, changing the positions of the air outlet pipe 27 and the sealing plate 26, and connecting the air outlet 2212 of the air driving assembly 22 with the other adapter 211, without the need of spare parts, which is convenient to operate and flexible to install, and the position of the external air exhaust pipe of the customer does not need to be known when the product is shipped, which provides convenience for the customer to purchase the product.

[0098] More specifically, the toe kick plate 50, the maintenance door 60 and the negative pressure box limiting plate 70 should be dismounted correspondingly before S10, and these parts can be returned to the original positions after the reversing operation is completed.

[0099] The embodiment also provides an integrated cooker, comprising a cooker and the air outlet structure of the integrated cooker. The cooker is installed above the rack mechanism 10, and the air inlet 213 of the flue assembly 30 is arranged towards the cooker.
