Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to an oil fume treatment device and an integrated stove. Background Technology

[0002] An integrated cooktop is a kitchen appliance that integrates multiple functions into one unit, such as a combination of "fume hood + cooktop + storage", "fume hood + cooktop + disinfection", or "fume hood + cooktop + steaming / baking".

[0003] In related technologies, integrated cooktops include a fume extraction device used to remove cooking fumes. Once fixed within the cooktop's frame, the fume extraction device exhausts smoke in one direction, allowing the integrated cooktop to be categorized into left-exhaust and right-exhaust models.

[0004] However, dividing integrated cooktops into two models leads to an increase in the number of stock keeping units (SKUs), which increases the burden of inventory management. Utility Model Content

[0005] This utility model provides an oil fume treatment device and an integrated stove to solve the problem that dividing the integrated stove into two models would lead to an increase in the number of stock keeping units (SKUs) and increase the burden of inventory management.

[0006] In a first aspect, embodiments of the present invention provide an oil fume treatment device, comprising:

[0007] A smoke collection device, the smoke collection device having a smoke collection chamber and a first air outlet and a second air outlet communicating with the smoke collection chamber;

[0008] A smoke exhaust device is disposed in the smoke collection chamber, and the smoke exhaust device is provided with a first smoke exhaust channel communicating with the first air outlet and a second smoke exhaust channel communicating with the second air outlet;

[0009] A volute assembly is disposed within the smoke collection chamber and is rotatably connected to the smoke exhaust component. The volute assembly is provided with a volute outlet and a functional component. The functional component is configured to drive the volute assembly to rotate so that the volute outlet of the volute assembly communicates with the first smoke exhaust channel or the second smoke exhaust channel.

[0010] In one possible implementation, the smoke exhaust component is provided with a first connecting plate and a second connecting plate, and the functional component includes a first functional plate and a second functional plate. The first functional plate is detachably connected to the first connecting plate when the volute outlet of the volute assembly is in communication with the second smoke exhaust channel, and the second functional plate is detachably connected to the second connecting plate when the volute outlet of the volute assembly is in communication with the first smoke exhaust channel.

[0011] With this configuration, when the fume treatment device is in the left exhaust mode, the volute outlet of the volute assembly is connected to the first exhaust channel, and the bent part of the second functional plate is connected to the second connecting plate of the exhaust component, which can make the volute assembly firmly fixed and not loose.

[0012] When the fume treatment device is in the right exhaust mode, the volute outlet of the volute assembly is connected to the second exhaust channel, and the bent part of the first functional plate is connected to the first connecting plate of the exhaust component, which can make the volute assembly firmly fixed and not loose.

[0013] In one possible implementation, the volute assembly has a first sealing end and a second sealing end in the circumferential direction of the volute outlet. The first sealing end is detachably connected to the second connecting plate when the volute outlet of the volute assembly is in communication with the second smoke exhaust channel, and the second sealing end is detachably connected to the first connecting plate when the volute outlet of the volute assembly is in communication with the first smoke exhaust channel.

[0014] With this configuration, when the fume treatment device is in the left exhaust state, the volute outlet of the volute assembly is connected to the first exhaust channel, the second functional plate is connected to the second connecting plate of the exhaust component, and the second sealing end of the volute assembly is connected to the first connecting plate of the exhaust component. Through the second functional plate of the volute assembly, the second sealing end of the volute assembly, and the rotation center of the volute assembly, three-point fixation can be formed to strengthen the stability of the volute assembly.

[0015] When the fume treatment device is in the right exhaust mode, the volute outlet of the volute assembly is connected to the second exhaust channel. The bent part of the first functional plate is connected to the first connecting plate of the exhaust component by screws. The first sealing end of the volute assembly is connected to the second connecting plate of the exhaust component by screws. The first functional plate of the volute assembly, the first sealing end of the volute assembly, and the rotation center of the volute assembly can form a three-point fixation to strengthen the stability of the volute assembly.

[0016] In one possible implementation, the smoke exhaust component is provided with an arc-shaped guide portion that communicates with both the inlet end of the first smoke exhaust channel and the inlet end of the second smoke exhaust channel;

[0017] The volute assembly includes a volute and a rotating bracket connected to the volute. The end of the volute is provided with an arc-shaped outlet section, and the volute outlet is located on the arc-shaped outlet section. The rotating bracket is provided with a first connecting platform that is rotatably connected to the smoke collecting component. The rotation center of the first connecting platform, the center of the arc-shaped outlet section, and the center of the arc-shaped guide portion coincide.

[0018] This configuration ensures that the volute assembly is subjected to uniform force during rotation, reduces offset caused by eccentricity, and improves the stability of the volute assembly during rotation.

[0019] In one possible implementation, a rotating shaft is also included, and a rotating disk fixedly connected to the first connecting platform is provided on the rotating bracket. A bearing is installed on the smoke collecting component, and the rotating shaft passes through the bearing and the rotating disk.

[0020] This configuration allows the rotating bracket to rotate relative to the smoke collection component via a rotating disk, rotating shaft, and bearings.

[0021] In one possible implementation, the rotating bracket is provided with a second connecting platform connected to the volute, and a plurality of connecting ribs are provided between the second connecting platform and the first connecting platform, with ventilation holes provided between adjacent connecting ribs.

[0022] This configuration allows airflow to be introduced from the side of the volute closest to the first side plate, providing effective heat dissipation for the motor as the airflow passes through it.

[0023] In one possible implementation, in the height direction of the fume treatment device, the center of the inlet end of the first exhaust channel is located on the side away from the bottom of the fume collection chamber from the center of the inlet end of the second exhaust channel.

[0024] The starting end of the volute is provided with a volute tongue segment and a first arc segment connected to the volute tongue segment. The radius of the first arc segment is smaller than the radius of the arc exit segment. A sealing plug and a volute oil leakage hole are provided on the first arc segment. The sealing plug is detachably installed in the volute oil leakage hole.

[0025] This design allows for the drainage of oil from the inside of the volute through a single oil drain hole, simplifying the structural design and reducing manufacturing costs and maintenance difficulty.

[0026] In one possible implementation, the sealing plug is connected to an anti-loss component, which is fixedly connected to the volute.

[0027] This design, with the sealing plug connected to the anti-loss component, prevents the sealing plug from falling off and being lost after it is pulled out of the oil leakage hole in the volute.

[0028] In one possible implementation, a sealing strip is provided at the edge of the volute outlet.

[0029] With this configuration, when the volute outlet is connected to the first smoke exhaust channel, the sealing strip seals the gap between the volute outlet and the first smoke exhaust channel to ensure no air leakage.

[0030] When the volute outlet is connected to the second smoke exhaust channel, the sealing strip seals the gap between the volute outlet and the second smoke exhaust channel to ensure no air leakage.

[0031] Secondly, this utility model embodiment provides an integrated stove, including the oil fume treatment device described in the first aspect.

[0032] This utility model provides an oil fume treatment device and an integrated stove. By manually driving the functional component, the volute assembly can be rotated, which can connect the volute outlet of the volute assembly with the first or second exhaust channel. This can realize the reversal of the exhaust direction of the volute assembly, so that the integrated stove does not need to be divided into left-row and right-row models. The variety of products is reduced, thereby reducing the number of stock keeping units (SKUs) and reducing the burden of inventory management. Attached Figure Description

Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0062] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0063] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0065] As described in the background section, dividing integrated cooktops into two models increases the number of stock keeping units (SKUs), thus increasing the burden of inventory management. Research has found that this problem arises because once the fume extraction device is fixed within the integrated cooktop frame, its airflow cannot be redirected. To meet the needs of different users, integrated cooktops are divided into left-row and right-row models. However, this division increases the variety of products, leading to a higher number of SKUs and thus a heavier inventory management burden.

[0066] The number of SKUs refers to the total number of product types.

[0067] To address the aforementioned problems, this utility model provides an oil fume treatment device and an integrated stove. It includes a functional component that can be manually driven to rotate the volute assembly. This allows the volute outlet of the volute assembly to connect with either the first or second exhaust channel, enabling the airflow direction of the volute assembly to be reversed. This eliminates the need to differentiate between left- and right-exhaust models for the integrated stove, reducing the variety of products and thus decreasing the number of stock keeping units (SKUs), thereby lowering the burden and cost of inventory management.

[0068] The fume treatment device and integrated stove provided in this utility model embodiment will be described in detail below with reference to specific embodiments.

[0069] First, see Figure 1 Define the length direction of the integrated stove as the X direction, the width direction as the Y direction, and the height and vertical direction as the Z direction.

[0070] This utility model embodiment provides an oil fume treatment device applied to an integrated stove. The integrated stove includes a lower unit 100, a stove body 200, and a fan assembly 300. The lower unit 100 mainly provides storage cabinet space and space for installing the oil fume treatment device. The stove body 200 mainly provides the burner for cooking. The fan assembly 300 is mainly used in conjunction with the oil fume treatment device to generate negative pressure to absorb the oil fumes generated during cooking. It is easy to understand that the fan assembly 300, the stove body 200, and the lower unit 100 are arranged sequentially along the Z direction and relatively fixedly connected to improve the stability of the integrated stove.

[0071] The length of the fume treatment device is the same as the length of the integrated stove, the width of the fume treatment device is the same as the width of the integrated stove, and the height of the fume treatment device is the same as the height of the integrated stove.

[0072] The side of the fume treatment device facing the +X direction is the left side of the fume treatment device. The side of the fume treatment device facing the -X direction is the right side of the fume treatment device.

[0073] In one possible implementation, see Figure 1 , Figure 2 and Figure 3 As shown, the fume treatment device includes a fume collection component 10.

[0074] The smoke collection component 10 has a smoke collection chamber and a first air outlet 106 and a second air outlet 107 communicating with the smoke collection chamber. The first air outlet 106 and the second air outlet 107 are arranged opposite to each other in the X direction.

[0075] The smoke collection component 10 is installed inside the frame 1000 of the lower-level machine 100. The smoke collection component 10 is located on one side of the frame 1000 in the -Y direction.

[0076] The smoke collection component 10 may include a front plate 101, a rear plate 102, a left side plate 103, a right side plate 104, and a cover plate 105. The front plate 101 and the rear plate 102 are arranged opposite each other in the Y direction, and the left side plate 103 and the right side plate 104 are arranged opposite each other in the X direction. The cover plate 105 is connected to one side of the front plate 101, the rear plate 102, the left side plate 103, the right side plate 104, and the cover plate 105 in the +Z direction. The front plate 101, the rear plate 102, the left side plate 103, the right side plate 104, and the cover plate 105 form a smoke collection chamber. A first air outlet 106 is provided on the left side plate 103. A second air outlet 107 is provided on the right side plate 104.

[0077] See Figure 3 , Figure 4 and Figure 5 As shown, the fume treatment device also includes a fume exhaust component 20.

[0078] The shape of the smoke exhaust component 20 can be L-shaped.

[0079] The smoke exhaust component 20 is installed inside the smoke collection chamber, and the smoke exhaust component 20 is located on one side of the smoke collection chamber in the -Z direction.

[0080] The smoke exhaust component 20 is provided with a first smoke exhaust channel 206 connected to the first air outlet 106 and a second smoke exhaust channel 207 connected to the second air outlet 107.

[0081] The smoke exhaust component 20 includes a base plate 201, a first connecting plate 202, and a second connecting plate 203. The base plate 201 can be formed by bending a plate towards the first connecting plate 202 and the second connecting plate 203. The base plate 201 has symmetrical semi-circular arc structures 208 on both sides in the Y direction, and the two semi-circular arc structures 208 form an arc guide portion. The first connecting plate 202 is located on one side of the second connecting plate 203 in the +Z direction.

[0082] The smoke exhaust component 20 also includes a first partition 204 and a second partition 205. The first partition 204 and the second partition 205 are disposed in the cavity formed by the bottom plate 201, the first connecting plate 202 and the second connecting plate 203. The first partition 204 and the second partition 205 can separate the first smoke exhaust channel 206 and the second smoke exhaust channel 207 in the cavity formed by the bottom plate 201, the first connecting plate 202 and the second connecting plate 203.

[0083] First smoke exhaust channel 206 and volute outlet 304 (see...) Figure 6 As shown, one end of the connection is the inlet end of the first smoke exhaust channel 206. The end of the second smoke exhaust channel 207 connected to the volute outlet 304 is the inlet end of the second smoke exhaust channel 207. Both the inlet ends of the first smoke exhaust channel 206 and the inlet ends of the second smoke exhaust channel 207 are connected to the arc-shaped guide portion.

[0084] In the height direction of the fume treatment device, the center of the inlet end of the first exhaust duct 206 is located on the side away from the bottom of the smoke collection chamber from the center of the inlet end of the second exhaust duct 207. That is, the center of the inlet end of the first exhaust duct 206 is located on the side of the center of the inlet end of the second exhaust duct 207 in the +Z direction.

[0085] The fume treatment device also includes a volute assembly. The volute assembly is provided with a volute outlet 304.

[0086] The volute assembly is located inside the smoke collection chamber and is rotatably connected to the smoke exhaust component 20.

[0087] See Figure 3 As shown, the volute assembly may include a volute 30. An impeller 50 and a motor are disposed within the volute 30. The motor drives the impeller 50, which generates negative pressure to draw away cooking fumes.

[0088] The rotation center of the volute 30 coincides with the center of the arc guide portion. The rotation axis of the volute 30 extends along the Y direction.

[0089] See in some examples Figure 6 As shown, the volute 30 includes a first side plate 301, a second side plate 302, and a surrounding plate 303. The first side plate 301 and the second side plate 302 are arranged opposite to each other in the Y direction. The first side plate 301 is located on one side in the +Y direction, and the second side plate 302 is located on one side in the -Y direction. The surrounding plate 303 connects the first side plate 301 and the second side plate 302.

[0090] See in some examples Figure 7As shown, the volute 30 is formed using a multi-segment arc method. The volute 30 includes a volute tongue segment 3030, a first arc segment 3031, a third arc segment 3033, a fourth arc segment 3034, a second arc segment 3032, and an arc exit segment 3035. One end of the first arc segment 3031 is connected to the volute tongue segment 3030, and the other end of the first arc segment 3031 is connected to the third arc segment 3033. The fourth arc segment 3034 connects the third arc segment 3033 and the second arc segment 3032. One end of the arc exit segment 3035 is connected to the second arc segment 3032.

[0091] The center of the circular exit segment 3035 is point a, the center of the second circular segment 3032 is point a, the center of the fourth circular segment 3034 is point b, the center of the third circular segment 3033 is point c, and the center of the first circular segment 3031 is point d. The point where the second circular segment 3032 and the circular exit segment 3035 intersect is point e. Figure 7 In the middle, the horizontal line passes through points a and e.

[0092] The starting end of the outer contour of the volute 30 includes the volute tongue segment 3030 and the first arc segment 3031.

[0093] The outer contour of the volute 30 includes an arc-shaped exit section 3035 at its end.

[0094] The enclosure 303 includes a volute tongue segment 3030, a first arc segment 3031, a third arc segment 3033, a fourth arc segment 3034, and a second arc segment 3032. The enclosure 303 does not include the arc exit segment 3035.

[0095] The volute outlet 304 is located on the arc-shaped outlet section 3035. In some examples, the arc length of the volute outlet 304 can be equal to the arc length of the arc-shaped outlet section 3035.

[0096] The radius of the first arc segment 3031 is smaller than the radius of the third arc segment 3033, the radius of the third arc segment 3033 is smaller than the radius of the fourth arc segment 3034, the radius of the fourth arc segment 3034 is smaller than the radius of the second arc segment 3032, and the radius of the second arc segment 3032 is equal to the radius of the arc exit segment 3035.

[0097] The volute assembly also includes a functional component configured to rotate the volute assembly, thereby connecting the volute outlet 304 of the volute assembly to the first exhaust duct 206 or the second exhaust duct 207. By manually driving the functional component, the volute assembly can be rotated, allowing the volute outlet 304 to connect to the first exhaust duct 206 or the second exhaust duct 207. This enables the airflow direction of the volute assembly to be reversed, eliminating the need to differentiate between left-exhaust and right-exhaust models for integrated cooktops. This reduces the variety of products, thereby reducing the number of stock keeping units (SKUs) and lowering inventory management burden and costs.

[0098] It should be noted that when the volute outlet 304 of the volute assembly is connected to the first exhaust duct 206, the fume treatment device is in the left exhaust state (see...). Figure 1 and Figure 3 (As shown). When the volute outlet 304 of the volute assembly is connected to the second exhaust duct 207, the fume treatment device is in the right exhaust state (see...). Figure 13 and Figure 14 (As shown).

[0099] In one possible implementation, see Figure 4 and Figure 5 As shown, a first oil drain hole 2111 is provided in the first exhaust duct 206, a second oil drain hole 2121 is provided in the second exhaust duct 207, and a third oil drain hole 2131 is provided between the first exhaust duct 206 and the second exhaust duct 207. When the fume treatment device is in the left exhaust mode, the oil in the fume can be drained through the first oil drain hole 2111 and finally discharged into the oil cup. When the fume treatment device is in the right exhaust mode, the oil in the fume can be drained through the second oil drain hole 2121 and finally discharged into the oil cup. The third oil drain hole 2131 is located between the first oil drain hole 2111 and the second oil drain hole 2121 and can assist in draining oil from the side wall of the exhaust component 20. This arrangement can prevent oil from accumulating when the exhaust direction of the volute assembly changes.

[0100] The bottom plate 201 of the smoke exhaust component 20 is provided with three oil collection parts. All three oil collection parts are recessed in the -Z direction.

[0101] The three oil collecting sections include a first oil collecting section 211, a third oil collecting section 213, and a second oil collecting section 212 arranged sequentially along the X direction. A first oil leakage hole 2111 is provided on the first oil collecting section 211, and the first oil leakage hole 2111 is located at the lowest point of the first oil collecting section 211 in the Z direction. A second oil leakage hole 2121 is provided on the second oil collecting section 212, and the second oil leakage hole 2121 is located at the lowest point of the second oil collecting section 212 in the Z direction. A third oil leakage hole 2131 is provided on the third oil collecting section 213, and the third oil leakage hole 2131 is located at the lowest point of the third oil collecting section 213 in the Z direction.

[0102] In one possible implementation, in the height direction of the fume treatment device, the center of the inlet end of the first exhaust channel 206 is located on the side away from the bottom of the smoke collection chamber from the center of the inlet end of the second exhaust channel 207. It can be understood that the center of the inlet end of the first exhaust channel 206 is higher than the center of the inlet end of the second exhaust channel 207 in the Z direction.

[0103] The volute 30 has a volute tongue segment 3030 and a first arc segment 3031 connected to the volute tongue segment 3030 at its starting end. The radius of the first arc segment 3031 is smaller than the radius of the arc exit segment 3035.

[0104] See Figure 3 , Figure 9 and Figure 10 As shown, a sealing plug 431 and a volute oil leakage hole 307 are provided on the first arc segment 3031. The sealing plug 431 is detachably installed in the volute oil leakage hole 307.

[0105] The sealing plug 431 can be made of rubber or silicone, etc.

[0106] In some examples, the sealing plug 431 can be engaged in the oil leakage hole 307 of the volute. The sealing plug 431 is interference-fitted with the oil leakage hole 307 of the volute.

[0107] When the fume treatment device is in the left exhaust mode, the sealing plug 431 is pulled out of the oil drain hole 307 of the volute housing, and the oil drain hole 307 is in the open state. At this time, the oil drain hole 307 is located at the lowest point of the volute housing 30 in the Z direction, which serves to drain the oil inside the volute housing 30. The oil can be discharged to the oil cup through the second oil drain hole 2121. When the fume treatment device is in the right exhaust mode, the oil drain hole 307 of the volute housing is higher than the volute housing outlet 304 in the Z direction. The sealing plug 431 is inserted into the oil drain hole 307, and the oil drain hole 307 is closed. The lowest point of the volute housing 30 in the Z direction is located at the volute housing outlet 304 and is connected to the second exhaust channel 207. The oil inside the volute housing 30 can be discharged to the oil cup through the second oil drain hole 2121. With this configuration, the function of draining oil inside the volute housing 30 is realized through only one oil drain hole on the volute housing 30, which simplifies the structural design and reduces manufacturing costs and maintenance difficulty.

[0108] It should be noted that when the fume treatment device is in the right exhaust mode, the sealing plug 431 is engaged with the oil leakage hole 307 of the volute to prevent gas leakage.

[0109] In one possible implementation, see Figure 10 As shown, the sealing plug 431 is connected to an anti-loss component 432, which is fixedly connected to the volute 30. This configuration, by connecting the sealing plug 431 to the anti-loss component 432, prevents the sealing plug 431 from falling off and being lost after it is pulled out of the oil leakage hole 307 in the volute.

[0110] In some examples, the anti-loss component 432 can be an anti-loss plug. The anti-loss plug can be made of silicone or rubber, etc.

[0111] The volute 30 is provided with a fixing hole 308, and the anti-loss plug can be stuck in the fixing hole 308 to fix the anti-loss plug to the volute 30.

[0112] In one possible implementation, the arc-shaped guide portion is provided with two flange structures 209 in the width direction of the fume treatment device (see...). Figure 4 As shown, two flanged structures 209 form a track, and the arc-shaped exit section 3035 rotates along the track. This arrangement allows the arc-shaped exit section 3035 of the volute 30 to rotate along the track, serving as a guide and improving stability during rotation. It also provides a seal for the volute exit 304. Furthermore, the flanged structure 209 enhances the strength of the arc-shaped guide section.

[0113] The flange structure 209 is located on the inner side of the semi-circular arc structure 208.

[0114] In one possible implementation, see Figures 6 to 8 As shown, the volute assembly includes a volute 30 and a rotating bracket 40 connected to the volute 30. The end of the volute 30 is provided with an arc-shaped outlet section 3035, and the volute outlet 304 is provided on the arc-shaped outlet section 3035. The rotating bracket 40 is provided with a first connecting platform 401 that is rotatably connected to the smoke collecting component 10. The rotation center of the first connecting platform 401, the center of the arc-shaped outlet section 3035, and the center of the arc-shaped guide portion coincide, ensuring that the volute assembly is subjected to uniform force during rotation, reducing the offset caused by eccentricity, and improving the stability of the volute assembly during rotation.

[0115] The first connecting platform 401 and the second connecting platform 402 can be circular in shape.

[0116] The rotating bracket 40 is provided with a second connecting platform 402 that connects to the volute 30. Multiple connecting ribs 403 are provided between the second connecting platform 402 and the first connecting platform 401, allowing the rotating bracket 40 to be eccentrically shaped like a frustum. It can be understood that the second connecting platform 402 and the first connecting platform 401 are spaced apart in the Y direction. The second connecting platform 402 of the rotating bracket 40 is fixed to the first side plate 301 of the volute 30. The first connecting platform 401, the second arc segment 3032, and the arc exit segment 3035 of the rotating bracket 40 are concentrically arranged, ensuring that when the volute assembly rotates around its center of rotation, the volute exit 304 always lies on the same arc segment, preventing eccentricity during rotation and thus avoiding sealing issues.

[0117] The second connecting platform 402 and the volute 30 can be connected by screws. The connecting rib 403 can be welded to the second connecting platform 402 and the first connecting platform 401 respectively.

[0118] The connecting rib 403 between the second connecting platform 402 and the first connecting platform 401 can strengthen the strength of the rotating bracket 40 and improve the stability of the volute 30 when it rotates.

[0119] Two adjacent connecting ribs 403 are provided with ventilation holes 404, which can introduce airflow from the side of the volute 30 near the first side plate 301. When the airflow flows through the motor, it can provide effective heat dissipation for the motor.

[0120] The air intake of the volute assembly mainly comes from the side where the second side plate 302 of the volute 30 is located. The side where the first side plate 301 of the volute 30 is located is the non-main air intake side.

[0121] In one possible implementation, see Figure 11 and Figure 12 As shown, the fume treatment device also includes a rotating shaft 63, a rotating disk 44 fixedly connected to the first connecting platform 401 on the rotating bracket 40, a bearing 13 installed on the fume collecting component 10, and the rotating shaft 63 passing through the bearing 13 and the rotating disk 44. This arrangement allows the rotating bracket 40 to rotate relative to the fume collecting component 10 via the rotating disk 44, the rotating shaft 63, and the bearing 13.

[0122] The smoke collecting component 10 is fixed with a retaining ring 14 by screws. The retaining ring 14 is equipped with a bearing 13 inside, and the retaining ring 14 and the outer ring of the bearing 13 are interference fit.

[0123] The rotating disk 44 can be circular. The axis of the first connecting platform 401 of the rotating bracket 40 is coaxial with the axis of the rotating disk 44, and the rotating disk 44 and the first connecting platform 401 can be fixedly connected by screws. The rotating disk 44 is provided with a protrusion 441 (see...). Figure 6 As shown, the protrusion 441 is inserted into the inner ring of the bearing 13, so that the protrusion 441 is locked to the end of the inner ring of the bearing 13, so that the rotating disk 44 rotates synchronously with the inner ring of the bearing 13.

[0124] The axis of bearing 13 coincides with the axis of rotating disk 44, and rotating shaft 63 passes through the inner ring of bearing 13 and rotating disk 44. The inner ring of bearing 13 is fitted with rotating shaft 63 by interference fit. Rotating shaft 63 and rotating disk 44 can be fixed with screws.

[0125] The smoke collecting component 10 is provided with a through hole 108 for mounting the retaining ring 14 (see...). Figure 2 As shown, a boss structure is provided around the through hole 108. The boss structure includes multiple frustums extending along the Y direction. The frustums are used to enhance the strength of the front plate 101 when the volute 30 rotates and prevent deformation.

[0126] In one possible implementation, one of the first air outlet 106 and the second air outlet 107 is open, while the other air outlet is closed. With this configuration, the fume treatment device can exhaust smoke from one of the first air outlet 106 and the second air outlet 107.

[0127] Among them, see Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, when the fume treatment device is in the left exhaust state, the volute outlet 304 of the volute assembly is connected to the first exhaust channel 206. The fume collector 10 has a first seat 11 on one side in the +X direction, which is connected to the first exhaust port 106 of the fume collector 10. The first seat 11 is used to connect to the outside of the integrated stove. The second exhaust port 107 of the fume collector 10 is sealed by the second sealing ring 1212 and the second sealing plate 1222, allowing the first exhaust port 106 to open and the second exhaust port 107 to close.

[0128] See Figure 5 , Figure 6 , Figure 13 and Figure 14 As shown, when the fume treatment device is in the right exhaust mode, the volute outlet 304 of the volute assembly is connected to the second exhaust channel 207. The fume collector 10 has a second seat 12 on one side in the -X direction, which is connected to the second exhaust port 107 of the fume collector 10. The second seat 12 is used to connect to the outside of the integrated stove. The first exhaust port 106 of the fume collector 10 is sealed by the first sealing ring 1211 and the first sealing plate 1221, allowing the second exhaust port 107 to open and the first exhaust port 106 to close.

[0129] It should be noted that when the fume treatment device is in the left-exhaust mode, the second seat 12, the first sealing ring 1211, and the first sealing plate 1221 are not required. When the fume treatment device is in the right-exhaust mode, the first seat 11, the second sealing ring 1212, and the second sealing plate 1222 are also not required. This arrangement reduces the cost of the fume treatment device.

[0130] In one possible implementation, see Figure 4 and Figure 6 As shown, the smoke exhaust component 20 is provided with a first connecting plate 202 and a second connecting plate 203. The functional components include a first functional plate 41 and a second functional plate 42. The first functional plate 41 is used to be detachably connected to the first connecting plate 202 when the volute outlet 304 of the volute assembly is connected to the second smoke exhaust channel 207. The second functional plate 42 is used to be detachably connected to the second connecting plate 203 when the volute outlet 304 of the volute assembly is connected to the first smoke exhaust channel 206.

[0131] The first functional board 41 and the second functional board 42 have the same structure. The structure of the second functional board 42 can be referenced from the structure of the first functional board 41.

[0132] See Figure 15As shown, both the first functional plate 41 and the second functional plate 42 include two connecting parts 411 and one bending part 412.

[0133] The two connecting portions 411 of the second functional plate 42 are respectively connected to the first side plate 301 and the second side plate 302 of the volute 30 by screws. Specifically, see Figure 3 and Figure 16 As shown, when the fume treatment device is in the left exhaust state, the volute outlet 304 of the volute assembly is connected to the first exhaust channel 206, and the bent part 412 of the second functional plate 42 is connected to the second connecting plate 203 of the exhaust component 20 by screws, which can make the volute assembly firmly fixed and not loose.

[0134] The two connecting portions 411 of the first functional plate 41 are respectively connected to the first side plate 301 and the second side plate 302 of the volute 30 by screws. Specifically, see 14 and Figure 17 As shown, when the fume treatment device is in the right exhaust state, the volute outlet 304 of the volute assembly is connected to the second exhaust channel 207, and the bent part 412 of the first functional plate 41 is connected to the first connecting plate 202 of the exhaust component 20 by screws, which can make the volute assembly firmly fixed and not loose.

[0135] It should be noted that when the air outlet direction of the volute assembly changes from left to right, the screws connecting the second functional plate 42 and the second connecting plate 203 are removed. Then, by manually driving the first functional plate 41 and the second functional plate 42, the volute assembly can be rotated, so that the volute outlet 304 of the volute assembly can be connected to the second smoke exhaust channel 207. The first functional plate 41 abuts against the first connecting plate 202, and the bent part 412 of the first functional plate 41 is connected to the first connecting plate 202 by screws.

[0136] When the air outlet direction of the volute assembly changes from right to left, the screws connecting the first functional plate 41 and the first connecting plate 202 are removed. Then, by manually driving the first functional plate 41 and the second functional plate 42, the volute assembly can be rotated, so that the volute outlet 304 of the volute assembly can be connected to the first smoke exhaust channel 206. The second functional plate 42 abuts against the second connecting plate 203, and the bent part 412 of the second functional plate 42 is connected to the second connecting plate 203 of the smoke exhaust component 20 by screws.

[0137] It should also be noted that when the volute assembly is installed with the exhaust component 20, the first functional plate 41 and the second functional plate 42 can be used as handles for easy handling. When the volute assembly rotates relative to the exhaust component 20, the first functional plate 41 and the second functional plate 42 can act as cranks. When the volute assembly is fixed relative to the exhaust component 20, the first functional plate 41 and the second functional plate 42 can act as locking components. This arrangement gives the first functional plate 41 and the second functional plate 42 three functions, improving integration and reducing costs.

[0138] In one possible implementation, a sealing strip is provided at the edge of the volute outlet 304. When the volute outlet 304 is connected to the first smoke exhaust channel 206, the sealing strip seals the gap between the volute outlet 304 and the first smoke exhaust channel 206 to ensure no air leakage. When the volute outlet 304 is connected to the second smoke exhaust channel 207, the sealing strip seals the gap between the volute outlet 304 and the second smoke exhaust channel 207 to ensure no air leakage.

[0139] The volute outlet 304 can be arc-shaped.

[0140] See Figure 6 and Figure 18 As shown, the volute outlet 304 is provided with a first arc-shaped groove 305 and a second arc-shaped groove 306 on both sides in the Y direction. The first arc-shaped groove 305 is fitted with a first sealing strip 33, and the second arc-shaped groove 306 is fitted with a second sealing strip 34.

[0141] See Figure 6 As shown, in the circumferential direction of the volute outlet 304, the two ends of the volute outlet 304 are a first sealing end 3041 and a second sealing end 3042, respectively. That is, the volute assembly has a first sealing end 3041 and a second sealing end 3042 in the circumferential direction of the volute outlet 304.

[0142] See Figures 19 to 21 As shown, the first sealing end 3041 is provided with a third sealing strip 35, and the second sealing end 3042 is provided with a fourth sealing strip 36. The third sealing strip 35 is fixed to the surrounding plate 303 of the volute 30 by the first pressure plate 31, and the fourth sealing strip 36 is fixed to the surrounding plate 303 of the volute 30 by the second pressure plate 32.

[0143] Both the third sealing strip 35 and the fourth sealing strip 36 extend along the Y direction. The third sealing strip 35, which is closer to the volute tongue section 3030, is parallel to the surrounding plate 303 of the volute housing 30, while the fourth sealing strip 36, which is farther from the volute tongue section 3030, is perpendicular to the tangent of the second arc segment 3032 of the volute housing 30.

[0144] The sealing strip at the edge of the volute outlet 304 includes a first sealing strip 33, a second sealing strip 34, a third sealing strip 35, and a fourth sealing strip 36. It can be understood that the first sealing strip 33, the second sealing strip 34, the third sealing strip 35, and the fourth sealing strip 36 surround the edge of the volute outlet 304, forming a continuous sealing structure.

[0145] The first pressure plate 31 and the second pressure plate 32 abut against both ends of the first sealing strip 33, preventing the first sealing strip 33 from sliding out of the first arc-shaped groove 305; the first pressure plate 31 and the second pressure plate 32 abut against both ends of the second sealing strip 34, preventing the second sealing strip 34 from sliding out of the second arc-shaped groove 306. This arrangement ensures the stability of the sealing structure.

[0146] In one possible implementation, the second sealing end 3042 is used to be detachably connected to the first connecting plate 202 when the volute outlet 304 of the volute assembly is connected to the first smoke exhaust channel 206, and the first sealing end 3041 is used to be detachably connected to the second connecting plate 203 when the volute outlet 304 of the volute assembly is connected to the second smoke exhaust channel 207.

[0147] Among them, see Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, when the fume treatment device is in the left exhaust state, the volute outlet 304 of the volute assembly is connected to the first exhaust channel 206, the bent part 412 of the second functional plate 42 is connected to the second connecting plate 203 of the exhaust component 20 by screws, and the second sealing end 3042 of the volute assembly is connected to the first connecting plate 202 of the exhaust component 20 by screws. Through the second functional plate 42 of the volute assembly, the second sealing end 3042 of the volute assembly and the rotation center of the volute assembly, a three-point fixation can be formed to strengthen the stability of the volute assembly.

[0148] See Figure 4 , Figure 6 , Figure 13 and Figure 14 As shown, when the fume treatment device is in the right exhaust mode, the volute outlet 304 of the volute assembly is connected to the second exhaust channel 207. The bent part 412 of the first functional plate 41 is connected to the first connecting plate 202 of the exhaust component 20 by screws. The first sealing end 3041 of the volute assembly is connected to the second connecting plate 203 of the exhaust component 20 by screws. The first functional plate 41 of the volute assembly, the first sealing end 3041 of the volute assembly, and the rotation center of the volute assembly can form a three-point fixation to strengthen the stability of the volute assembly.

[0149] It should be noted that when the air outlet direction of the volute assembly changes from left to right, the screws connecting the second functional plate 42 and the second connecting plate 203, as well as the screws connecting the second sealing end 3042 and the first connecting plate 202, are removed. Afterwards, by manually driving the first functional plate 41 and the second functional plate 42, the volute assembly can be rotated in the -W direction (counterclockwise), so that the volute outlet 304 of the volute assembly can be connected to the second smoke exhaust channel 207. The first functional plate 41 abuts against the first connecting plate 202, and the bent part 412 of the first functional plate 41 is connected to the first connecting plate 202 by screws. The first sealing end 3041 abuts against the second connecting plate 203, and the first sealing end 3041 is connected to the second connecting plate 203 by screws.

[0150] When the air outlet direction of the volute assembly changes from right to left, the screws connecting the first functional plate 41 and the first connecting plate 202 are removed, as are the screws connecting the first sealing end 3041 and the second connecting plate 203. Then, by manually driving the first functional plate 41 and the second functional plate 42, the volute assembly can be rotated in the +W direction (clockwise), so that the volute outlet 304 of the volute assembly can be connected to the first smoke exhaust channel 206. The second functional plate 42 abuts against the second connecting plate 203, and the bent part 412 of the second functional plate 42 is connected to the second connecting plate 203 of the smoke exhaust component 20 by screws. The second sealing end 3042 abuts against the first connecting plate 202 and is connected to the first connecting plate 202 by screws.

[0151] The integrated stove in this embodiment of the utility model, by including the fume treatment device in the aforementioned embodiment, can reduce the number of stock keeping units (SKUs), thereby reducing the burden and cost of inventory management.

[0152] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
