Description

Technical Field

[0001] The present invention relates to the technical field of cooking equipment, and in particular to an oil fume treatment device and an integrated stove. Background Art

[0002] An integrated stove is a kitchen appliance that integrates multiple functions into one, such as: "smoke + stove + storage", "smoke + stove + disinfection", "smoke + stove + steaming / baking" and other combinations of functions.

[0003] In the prior art, integrated stoves include a fume treatment device, which is used to exhaust cooking fumes. After being fixed to the integrated stove frame, the fume treatment device exhausts fumes in one direction, thus differentiating the integrated stoves into left- and right-flow models.

[0004] However, the division of integrated stoves into two models will lead to an increase in the number of stock keeping units (SKUs), increasing the inventory management burden and cost pressure. Summary of the Invention

[0005] An embodiment of the present invention provides an oil fume treatment device and an integrated stove to solve the problem that the number of stock keeping units (SKUs) increases after the integrated stoves are divided into two models, thereby increasing the inventory management burden and cost pressure.

[0010] In a possible embodiment, the smoke chamber assembly includes a smoke exhaust piece, which is arranged in the smoke collecting chamber, and the smoke exhaust piece is provided with a first smoke exhaust channel connected to the first air outlet and a second smoke exhaust channel connected to the second air outlet. The volute assembly is rotatably connected to the smoke exhaust piece, and the volute outlet is connected to the first smoke exhaust channel or the second smoke exhaust channel.

[0011] In this way, when the driving component drives the volute component to rotate, so that the volute outlet is connected to the first smoke exhaust channel, the volute outlet can be connected to the first air outlet through the first smoke exhaust channel; or, when the driving component drives the volute component to rotate, so that the volute outlet is connected to the second smoke exhaust channel, the volute outlet can be connected to the second air outlet through the second smoke exhaust channel.

[0012] In a possible embodiment, a control unit is further included, and the drive assembly includes a push rod motor and a drive arm, the push rod motor is installed on the smoke collecting component, the push rod motor is movably connected to the drive arm, the drive arm is connected to the volute assembly, and the push rod motor is electrically connected to the control unit.

[0013] With this arrangement, the control unit controls the extension and retraction of the push rod of the push rod motor, the push rod drives the drive arm to move, and the drive arm drives the volute assembly to rotate, thereby achieving high performance indicators of the integrated stove, such as intelligence.

[0014] In a possible embodiment, the smoke exhaust member is provided with an arc guide portion connected to both the inlet end of the first smoke exhaust channel and the inlet end of the second smoke exhaust channel;

[0015] The volute assembly includes a volute and a rotating bracket. The end of the volute is provided with an arc outlet section, and the volute outlet is provided on the arc outlet section. The rotating bracket is provided with a first connecting platform that is rotatably connected to the smoke collecting part. The first connecting platform, the arc outlet section and the arc guide part are concentrically arranged.

[0016] With such an arrangement, by using the center of the circle where the first connecting platform, the arc outlet section and the arc guide portion coincide as the rotation center, the stability of the volute assembly during rotation can be improved, the deviation can be reduced, and the left and right air outlet reversing function of the volute assembly can be realized.

[0017] In a possible embodiment, the arc guide portion is provided with two flange structures in the width direction of the oil fume treatment device, and the two flange structures form a track, and the arc outlet section rotates along the track.

[0018] With this arrangement, the arc outlet section of the volute can rotate along the track, which can play a guiding role, improve the stability during rotation, and also seal the volute outlet. In addition, the flange structure can also enhance the strength of the arc guide portion.

[0019] In a possible embodiment, the volute is provided with a second arc segment connected to the arc outlet segment, the radius of the second arc segment is equal to the radius of the arc outlet segment, the second arc segment and the arc outlet segment are concentrically arranged, and the second arc segment is used to block the first smoke exhaust channel when the volute outlet is connected to the second smoke exhaust channel.

[0020] In a possible embodiment, the rotating bracket is provided with a second connecting platform connected to the volute, a plurality of connecting ribs are provided between the second connecting platform and the first connecting platform, and ventilation holes are provided between two adjacent connecting ribs.

[0022] In a possible embodiment, the smoke chamber assembly is provided with a limiting seat, an electric lock is provided in the limiting seat, and the volute assembly is provided with a limiting plate, and the limiting plate is configured to abut against the limiting seat and be fixed by the electric lock when the volute outlet of the volute assembly is connected to the first air outlet or the second air outlet.

[0023] With such a configuration, when the volute outlet of the volute assembly is connected to the first air outlet or the second air outlet, the volute assembly is firmly fixed and not loosened through the limiting plate and the limiting seat, thereby improving the stability of the system during operation and preventing position displacement due to vibration or airflow impact during operation.

[0024] In a possible embodiment, a detection component is provided on the smoke chamber assembly, and the detection component is used to determine whether the volute assembly is in place.

[0025] This arrangement can locate the rotation angle of the volute assembly, avoid position deviation, and improve operational stability.

[0026] In a possible implementation manner, a sealing strip is provided on the edge of the volute outlet.

[0027] Such a setting can ensure that there is no air leakage when the air outlet direction of the volute assembly is automatically reversed, thereby improving operating efficiency.

[0028] In a possible embodiment, in the height direction of the oil fume treatment device, the center of the inlet end of the first smoke exhaust channel is arranged on a side of the center of the inlet end of the second smoke exhaust channel away from the bottom of the smoke collecting chamber;

[0030] With this arrangement, the oil drainage function inside the volute is achieved by simply opening and closing an oil leakage hole on the volute, which simplifies the structural design, improves reliability, and reduces manufacturing costs and maintenance difficulty.

[0031] In a possible implementation, a bearing is fixed to the smoke collecting member, a rotating disk is provided on the rotating bracket, and the driving assembly is connected to a rotating shaft, which passes through the inner ring of the bearing and the rotating disk.

[0032] Such an arrangement effectively reduces direct contact between the rotating disk and the smoke collecting member through the use of bearings, lowers the friction coefficient, reduces wear, extends the service life, and reduces the load borne by the push rod motor.

[0033] In a possible implementation manner, the smoke collecting member is provided with a through hole for the rotating shaft to pass through, and a boss structure is provided around the through hole.

[0034] In a possible implementation, a first oil leakage hole is provided in the first smoke exhaust channel, a second oil leakage hole is provided in the second smoke exhaust channel, and a third oil leakage hole is provided between the first smoke exhaust channel and the second smoke exhaust channel.

[0035] In a possible implementation manner, one of the first air outlet and the second air outlet is open, and the other air outlet is closed.

[0037] In a second aspect, an embodiment of the present invention provides an integrated stove, comprising the oil fume treatment device described in the first aspect.

[0038] An embodiment of the present invention provides an oil fume treatment device and an integrated stove. By driving the volute assembly through a driving assembly, the volute outlet of the volute assembly can be connected to the first air outlet or the second air outlet, and the air outlet direction of the volute assembly can be automatically reversed, so that the integrated stove does not need to be divided into left-row models and right-row models, and the variety of products is reduced, thereby reducing the number of stock keeping units (SKUs), reducing the inventory management burden and cost pressure. When the air outlet direction of the volute assembly is automatically reversed, the volute assembly does not need to be manually disassembled, thereby avoiding the problem of difficult installation of the volute outlet.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features.

In addition, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0079] As described in the background, the division of integrated stoves into two models increases the number of stock-keeping units (SKUs), increasing the burden of inventory management and cost pressure. Research has found that this problem arises because the fume treatment device, once fixed to the integrated stove frame, cannot reverse its airflow direction. To meet the needs of different users, the integrated stoves are divided into left-row and right-row models. However, this division increases the number of stock-keeping units (SKUs), increasing the burden of inventory management and cost pressure.

[0080] The number of SKUs refers to the total number of product types.

[0081] In order to solve the above problems, an embodiment of the present invention provides an oil fume treatment device and an integrated stove, in which a driving component is provided. The driving component drives the volute component to move, so that the volute outlet of the volute component can be connected to the first air outlet or the second air outlet of the smoke collecting component, and the air outlet direction of the volute component can be automatically reversed, so that the integrated stove does not need to be divided into left-row models and right-row models, and the types of goods are reduced, thereby reducing the number of stock units (SKUs), reducing the inventory management burden and cost pressure, and improving production efficiency and market response speed.

[0082] The oil fume treatment device and the integrated stove provided by the embodiments of the present invention are described in detail below with reference to specific embodiments.

[0083] Example 1

[0084] First, see Figure 1 , define the length direction of the integrated stove as the X direction, define the width direction of the integrated stove as the Y direction, and define the height direction and vertical direction of the integrated stove as the Z direction.

[0085] First, embodiments of the present invention provide an oil fume treatment device for use in an integrated stove. The integrated stove comprises a lower unit 100, a stove body 200, and a head assembly 300. The lower unit 100 primarily provides storage cabinet space and space for the oil fume treatment device. The stove body 200 primarily houses the stove head for cooking. The head assembly 300 is primarily used in conjunction with the oil fume treatment device to generate negative pressure to absorb cooking fumes. As will be appreciated, the head assembly 300, stove body 200, and lower unit 100 are sequentially arranged along the Z direction and relatively fixedly connected to enhance the stability of the integrated stove.

[0086] The length direction of the oil fume treatment device is the same as the length direction of the integrated stove, the width direction of the oil fume treatment device is the same as the width direction of the integrated stove, and the height direction of the oil fume treatment device is the same as the height direction of the integrated stove.

[0087] The side of the oil fume treatment device in the +X direction is the left side of the oil fume treatment device, and the side of the oil fume treatment device in the -X direction is the right side of the oil fume treatment device.

[0088] In a possible implementation, the oil fume treatment device includes a fume chamber assembly.

[0089] See also Figure 2 and Figure 3 As shown, the smoke chamber assembly includes a smoke collecting member 10, which has a smoke collecting chamber and a first air outlet 106 communicating with the smoke collecting chamber (see Figure 12 As shown), the first air outlet 106 and the second air outlet 107 are arranged opposite to each other in the X direction.

[0090] The smoke collecting element 10 is installed inside the frame 1000 of the lower computer 100. The smoke collecting element 10 is located on one side of the frame 1000 in the -Y direction.

[0091] The smoke collection element 10 may include a front panel 101, a rear panel 102, a left panel 103, a right panel 104, and a cover panel 105. The front panel 101 and the rear panel 102 are positioned opposite each other in the Y direction, and the left panel 103 and the right panel 104 are positioned opposite each other in the X direction. The cover panel 105 is connected to one side of the front panel 101, the rear panel 102, the left panel 103, and the right panel 104 in the +Z direction. The front panel 101, the rear panel 102, the left panel 103, the right panel 104, and the cover panel 105 form a smoke collection chamber. A first air outlet 106 is provided on the left panel 103. A second air outlet 107 is provided on the right panel 104.

[0092] The oil fume treatment device further comprises a volute assembly which is movably arranged in the smoke collecting chamber and is provided with a volute outlet 304 .

[0093] Among them, see Figure 4 and Figure 5As shown, the volute assembly may include a volute 30. An impeller 50 is provided in the volute 30 (see Figure 19 As shown) and a motor, the motor drives the impeller 50, and the impeller 50 generates negative pressure to absorb the oil smoke generated during cooking.

[0094] In some examples, 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 relative to each other in the Y direction. The first side plate 301 is arranged on one side of the +Y direction, the second side plate 302 is arranged on one side of the -Y direction, and the surrounding plate 303 is connected between the first side plate 301 and the second side plate 302.

[0095] For some examples, see Figure 6 As shown, the volute 30 is formed using a multi-segment arc method. The volute 30 is provided with a 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 outlet segment 3035. One end of the first arc segment 3031 is connected to the tongue segment 3030, the other end of the first arc segment 3031 is connected to the third arc segment 3033, the fourth arc segment 3034 is connected between the third arc segment 3033 and the second arc segment 3032, and one end of the arc outlet segment 3035 is connected to the second arc segment 3032.

[0096] The center of the arc exit segment 3035 is point a, the center of the second arc segment 3032 is point a, the center of the fourth arc segment 3034 is point b, the center of the third arc segment 3033 is point c, and the center of the first arc segment 3031 is point d. The point where the second arc segment 3032 and the arc exit segment 3035 intersect is point e. Figure 6 In the example, the horizontal line passes through points a and e.

[0097] The starting end of the outer contour of the volute 30 includes a volute tongue segment 3030 and a first circular arc segment 3031 .

[0098] The end of the outer contour of the volute 30 includes a circular arc outlet section 3035 .

[0099] The enclosure 303 includes a volute tongue segment 3030 , a first circular arc segment 3031 , a third circular arc segment 3033 , a fourth circular arc segment 3034 and a second circular arc segment 3032 . The enclosure 303 does not include a circular arc outlet segment 3035 .

[0100] The volute outlet 304 is disposed on the arc outlet segment 3035. In some examples, the arc length of the volute outlet 304 may be equal to the arc length of the arc outlet segment 3035.

[0101] 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 .

[0102] The oil fume treatment device also includes a drive assembly. The drive assembly is installed on the smoke chamber assembly, and the drive assembly is connected to the volute assembly. The drive assembly is configured to drive the volute assembly to move so that the volute outlet 304 of the volute assembly is connected to the first air outlet 106 or the second air outlet 107. With such a setting, the air outlet direction of the volute assembly can be automatically reversed, so that the integrated stove does not need to be divided into left-row models and right-row models, and the variety of goods is reduced, thereby reducing the number of stock keeping units (SKUs), reducing the inventory management burden and cost pressure, and improving production efficiency and market response speed. In addition, when the air outlet direction of the volute assembly is automatically reversed, the volute assembly does not need to be manually disassembled, which can avoid the problem of difficult installation of the volute outlet 304.

[0103] It should be noted that when the volute outlet 304 of the volute assembly is connected to the first air outlet 106, the oil fume treatment device is in the left air outlet state. When the volute outlet 304 of the volute assembly is connected to the second air outlet 107, the oil fume treatment device is in the right air outlet state.

[0104] In one possible implementation, see Figure 4 、 Figure 8 and Figure 9 As shown, the smoke chamber assembly further includes a smoke exhaust member 20. The smoke exhaust member 20 is disposed in the smoke collecting chamber and is located on one side of the smoke collecting chamber in the -Z direction.

[0105] The smoke exhaust member 20 is provided with a first smoke exhaust passage 206 communicating with the first air outlet 106 and a second smoke exhaust passage 207 communicating with the second air outlet 107. The volute assembly is rotatably connected to the smoke exhaust member 20, and the volute outlet 304 is connected to the first smoke exhaust passage 206 or the second smoke exhaust passage 207. In this configuration, when the drive assembly drives the volute assembly to rotate so that the volute outlet 304 is connected to the first smoke exhaust passage 206, the volute outlet 304 can communicate with the first air outlet 106 through the first smoke exhaust passage 206; or, when the drive assembly drives the volute assembly to rotate so that the volute outlet 304 is connected to the second smoke exhaust passage 207, the volute outlet 304 can communicate with the second air outlet 107 through the second smoke exhaust passage 207.

[0106] The smoke exhaust element 20 may be in an L-shape.

[0107] See also Figure 8 and Figure 9As shown, the smoke exhaust element 20 includes a bottom plate 201, a left upper plate 202, and a right upper plate 203. The bottom plate 201 can be formed by bending a single plate toward the left upper plate 202 and the right upper plate 203. Symmetrical semicircular structures 208 are provided on both sides of the bottom plate 201 in the Y direction. The two semicircular structures 208 form arc guides. The left upper plate 202 is located on the +Z side of the right upper plate 203.

[0108] The smoke exhaust part 20 also includes a first partition 204 and a second partition 205, which are arranged in a cavity surrounded by the bottom plate 201, the upper left plate 202 and the upper right plate 203. The first partition 204 and the second partition 205 can separate a first smoke exhaust channel 206 and a second smoke exhaust channel 207 in the cavity surrounded by the bottom plate 201, the upper left plate 202 and the upper right plate 203.

[0109] The end of the first smoke exhaust channel 206 connected to the volute outlet 304 is the inlet 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 of the second smoke exhaust channel 207. The inlet of the first smoke exhaust channel 206 and the inlet of the second smoke exhaust channel 207 are both connected to the arc guide portion.

[0110] In the height direction of the oil fume treatment device, the center of the inlet end of the first smoke exhaust channel 206 is set on the side of the center of the inlet end of the second smoke exhaust channel 207 away from the bottom of the smoke collecting chamber, that is, the center of the inlet end of the first smoke exhaust channel 206 is set on the +Z direction side of the center of the inlet end of the second smoke exhaust channel 207.

[0111] 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.

[0112] In one possible embodiment, a first oil leakage hole 2111 is provided in the first smoke exhaust channel 206, a second oil leakage hole 2121 is provided in the second smoke exhaust channel 207, and a third oil leakage hole 2131 is provided between the first smoke exhaust channel 206 and the second smoke exhaust channel 207. When the oil fume treatment device is in the left air outlet state, the oil in the oil fume can be discharged through the first oil leakage hole 2111 and finally discharged into the oil cup. When the oil fume treatment device is in the right air outlet state, the oil in the oil fume can be discharged through the second oil leakage hole 2121 and finally discharged into the oil cup. The third oil leakage hole 2131 is located between the first oil leakage hole 2111 and the second oil leakage hole 2121, and can assist in draining the oil on the side wall of the smoke exhaust component 20. This arrangement can prevent the deposition of oil when the air outlet direction of the volute assembly is automatically reversed.

[0113] The bottom plate 201 of the smoke exhaust member 20 is provided with three oil collecting portions, all of which are recessed toward the -Z direction.

[0114] 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, which are arranged sequentially along the X-direction. A first oil leakage hole 2111 is provided in the first oil collecting section 211, located at the lowest point of the first oil collecting section 211 in the Z-direction. A second oil leakage hole 2121 is provided in the second oil collecting section 212, located at the lowest point of the second oil collecting section 212 in the Z-direction. A third oil leakage hole 2131 is provided in the third oil collecting section 213, located at the lowest point of the third oil collecting section 213 in the Z-direction.

[0115] In one possible embodiment, in the height direction of the oil fume treatment device, the center of the inlet end of the first smoke exhaust channel 206 is set on the side of the center of the inlet end of the second smoke exhaust channel 207 away from the bottom of the smoke collecting chamber. It can be understood that the center of the inlet end of the first smoke exhaust channel 206 is higher than the center of the inlet end of the second smoke exhaust channel 207 in the Z direction.

[0116] The starting end of the volute 30 is provided with a volute tongue section 3030 and a first arc section 3031 connected to the volute tongue section 3030 . The radius of the first arc section 3031 is smaller than the radius of the arc outlet section 3035 .

[0117] See also Figure 4 and Figure 5 As shown, the first arc segment 3031 is provided with an on-off valve 43 and a volute oil leakage hole 307. The on-off valve 43 opens or closes the volute oil leakage hole 307. This arrangement enables the oil discharge function within the volute 30 to be achieved by opening and closing only one oil leakage hole on the volute 30, simplifying the structural design, improving reliability, and reducing manufacturing costs and maintenance difficulties.

[0118] In some examples, the switch valve 43 can be a solenoid valve. When the oil fume treatment device is in the left air outlet state, the solenoid valve is open, and the volute oil leakage hole 307 is in an open state. At this time, the volute oil leakage hole 307 is located at the lowest point of the volute 30 in the Z direction, serving to discharge oil and dirt inside the volute 30, and can be discharged to the oil cup through the second oil leakage hole 2121. When the oil fume treatment device is in the right air outlet state, the solenoid valve is closed, and the volute oil leakage hole 307 is closed. At this time, the lowest point of the volute 30 in the Z direction is located at the volute outlet 304 and is connected to the second exhaust channel 207. The oil and dirt inside the volute 30 can be discharged to the oil cup through the second oil leakage hole 2121.

[0119] In one possible embodiment, the arc guide portion is provided with two flange structures 209 along the width of the oil fume treatment device. These flange structures 209 form a track along which the arc outlet section 3035 rotates. This arrangement allows the arc outlet section 3035 of the volute 30 to rotate along the track, providing a guide and improving stability during rotation while also sealing the volute outlet 304. Furthermore, the flange structures 209 enhance the strength of the arc guide portion.

[0120] The flange structure 209 is arranged on the inner side of the semicircular arc structure 208 .

[0121] In a possible implementation, the oil fume treatment device further includes a control unit.

[0122] See also Figures 2 to 4 As shown, the drive assembly includes a push rod motor 61 and a drive arm 62. The push rod motor 61 is mounted on the smoke collector 10 and is movably connected to the drive arm 62. The drive arm 62 is connected to the volute assembly. The push rod motor 61 is electrically connected to the control unit. This arrangement allows the control unit to control the extension and retraction of the push rod of the push rod motor 61, which in turn drives the movement of the drive arm 62, which in turn drives the rotation of the volute assembly. This can achieve high performance indicators of the integrated stove, such as intelligence.

[0123] The push rod motor 61 is connected to the motor fixing base 60 by rotation, and the motor fixing base 60 is fixed on the front plate 101 of the smoke collecting component 10 .

[0124] In one possible implementation, see Figures 5 to 7 As shown, the volute assembly includes a volute 30 and a rotating bracket 40. The end of the volute 30 is provided with an arc outlet section 3035, and the volute outlet 304 is provided on the arc outlet section 3035. The rotating bracket 40 is provided with a first connecting platform 401 that is rotatably connected to the smoke collecting element 10. The first connecting platform 401, the arc outlet section 3035, and the arc guide portion are arranged concentrically. This arrangement, using the center of the circle where the first connecting platform 401, the arc outlet section 3035, and the arc guide portion coincide as the center of rotation, can improve the stability of the volute assembly during rotation, reduce deviation, and realize the volute assembly's left and right air outlet reversing function.

[0125] The first connecting platform 401 is circular in shape.

[0126] The rotating bracket 40 is provided with a second connecting platform 402 connected to the volute 30. A plurality of connecting ribs 403 are provided between the second connecting platform 402 and the first connecting platform 401, so that the rotating bracket 40 can be eccentrically truncated. It is understandable 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 welded and fixed to the first side plate 301 of the volute 30. The first connecting platform 401, the second arc segment 3032 and the arc outlet segment 3035 of the rotating bracket 40 are concentrically arranged to ensure that when the volute assembly rotates about the rotation center, the volute outlet 304 is always located on the same arc segment, avoiding eccentricity during rotation and resulting in non-sealing.

[0127] 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 during rotation.

[0128] Two adjacent connecting ribs 403 are provided with ventilation holes 404, which can introduce airflow from the side of the volute 30 close to the first side plate 301. When the airflow flows through the motor, it can provide effective heat dissipation for the motor.

[0129] The air inlet of the volute assembly mainly enters 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 inlet side.

[0130] In one possible implementation, see Figure 10 and Figure 11 As shown, the smoke collecting element 10 is fixed with a bearing 13, a rotating disk 44 is provided on the rotating bracket 40, and a rotating shaft 63 is connected to the drive assembly. The rotating shaft 63 passes through the inner ring of the bearing 13 and the rotating disk 44. This arrangement effectively reduces direct contact between the rotating disk 44 and the smoke collecting element 10 through the use of the bearing 13, thereby reducing the friction coefficient, reducing wear, extending the service life, and reducing the load borne by the push rod motor 61.

[0131] Among them, a fixing ring 14 is fixed on the smoke collecting member 10, and the fixing ring 14 has an interference fit with the outer ring of the bearing 13, thereby preventing the outer ring of the bearing 13 from loosening or displacement during operation, thereby improving the rigidity and reliability of the overall structure.

[0132] The shape of the rotating disk 44 can be circular. The axis of the first connecting platform 401 of the rotating bracket 40 is coaxially arranged with the axis of the rotating disk 44, and the rotating disk 44 is fixedly connected to the first connecting platform 401. The rotating disk 44 is provided with a protrusion 441, and the protrusion 441 is inserted into the inner ring of the bearing 13, so that the protrusion 441 is locked and connected to the end of the inner ring of the bearing 13, so that the rotating disk 44 and the inner ring of the bearing 13 rotate synchronously. With such an arrangement, the use of the bearing 13 effectively reduces the direct contact between the rotating disk 44 and the smoke collecting part 10, reduces the friction coefficient, reduces wear, extends the service life, and reduces the load borne by the push rod motor 61.

[0133] The inner ring of the bearing 13 is sleeved with the rotating shaft 63 through an interference fit. The rotating shaft 63 passes through the inner ring of the bearing 13 and the rotating disk 44. The rotating shaft 63 is locked on the rotating disk 44, ensuring the coaxiality and stability between the rotating disk 44 and the rotating shaft 63, reducing radial runout and axial movement during rotation, and improving rotation accuracy and running smoothness.

[0134] A portion of the rotating shaft 63 extends toward the side of the front plate 101 of the smoke collecting component 10 away from the volute 30, and extends beyond the front plate 101 of the smoke collecting component 10. A notch is provided at the end of the rotating shaft 63 away from the volute 30, and the driving arm 62 of the driving assembly is connected to the notch by screw locking, ensuring that the relative position of the driving arm 62 and the rotating shaft 63 is fixed, realizing precise control and positioning of the rotational motion, and avoiding deviation in the transmission process.

[0135] The smoke collecting member 10 is provided with a through hole 108 for the rotation shaft 63 to pass through (see Figure 3 As shown in FIG, a boss structure is provided around the through hole 108. The boss structure includes a plurality of frustums extending along the Y direction, which are used to enhance the strength of the front plate 101 when the volute 30 rotates and prevent deformation.

[0136] In a possible embodiment, one of the first air outlet 106 and the second air outlet 107 is open and the other is closed. In this configuration, the oil fume treatment device can exhaust smoke from one of the first air outlet 106 and the second air outlet 107 .

[0137] Among them, see Figure 2 and Figure 12 As shown, the smoke collector 10 is provided with a first seat 11 on one side in the +X direction and a second seat 12 on the other side in the -X direction. The first seat 11 is connected to the first air outlet 106, and the second seat 12 is connected to the second air outlet 107. The first seat 11 and the second seat 12 are used to communicate with the outside of the integrated stove.

[0138] The second arc segment 3032 and the arc outlet segment 3035 of the volute 30 are concentrically arranged. The second arc segment 3032 can block the first smoke exhaust channel 206 when the volute outlet 304 is connected to the second smoke exhaust channel 207 .

[0139] When the integrated stove leaves the factory, the oil fume treatment device can be set to the left air outlet state. The first seat 11 is connected to the outside of the integrated stove, and the second seat 12 is sealed by the sealing ring 121 and the blocking plate 122, so that the first air outlet 106 can be opened and the second air outlet 107 can be closed. With this arrangement, during the installation of the integrated stove, the entire machine can be installed into the cabinet without confirming the required air outlet direction. When the user requires left air outlet, it can be installed in the default factory state; when the user requires right air outlet, the oil fume treatment device is adjusted to the right air outlet state through the control unit. At this time, the second arc section 3032 of the volute 30 can block the first smoke exhaust channel 206, and the oil fume can be completely discharged into the second smoke exhaust channel 207. The right air outlet state can be achieved by simply removing the sealing ring 121 and the blocking plate 122 on the second seat 12. When the default left air outlet state is set, the second seat 12 is sealed by the sealing ring 121 and the blocking plate 122, so that the second air outlet 107 is closed. When it is adjusted to the right air outlet state, the second arc section 3032 of the volute 30 can block the first smoke exhaust channel 206, so that the first air outlet 106 is closed, so that there is no need for complicated adjustments during the installation of the integrated stove, reducing the risk of installation errors due to operational errors.

[0140] In one possible embodiment, the smoke chamber assembly is provided with a limit seat, an electric lock is provided in the limit seat, and the volute assembly is provided with a limit plate, and the limit plate is configured to abut against the limit seat and be fixed by the electric lock when the volute outlet 304 of the volute assembly is connected with the first air outlet 106 or the second air outlet 107. In this way, when the volute outlet 304 of the volute assembly is connected with the first air outlet 106 or the second air outlet 107, the limit plate abuts against the limit seat and is fixed by the electric lock, which can make the volute assembly firmly fixed and not loose, thereby improving the stability of the system during operation and preventing position displacement due to vibration or airflow impact during operation.

[0141] Among them, the electric lock can fix the limit plate after power is off and can unlock the limit plate after power is on.

[0142] In some examples, the electric lock may be an electromagnetic lock. The electromagnetic lock includes a body and a latch. When the electromagnetic lock is powered off, the latch pops out of the body; when the electromagnetic lock is powered on, the latch retracts into the body.

[0143] See also Figure 4 、 Figure 15 and Figure 16 As shown, the limiting seat of the smoke chamber assembly includes a first limiting seat 21 and a second limiting seat 22.

[0144] The first limiting seat 21 is mounted on the upper left plate 202 of the smoke exhaust member 20 , and a first electromagnetic lock 23 is disposed in the first limiting seat 21 .

[0145] The second limiting seat 22 is installed on the upper right plate 203 of the smoke exhaust member 20. A second electromagnetic lock 24 is provided in the second limiting seat 22 (see Figure 14 shown).

[0146] The limiting plates of the volute assembly include a first limiting plate 41 and a second limiting plate 42. The first limiting plate 41 and the second limiting plate 42 are located on one side of the enclosing plate 303 of the volute 30. The first limiting plate 41 is connected to the first side plate 301 and the second side plate 302 of the volute 30, respectively. The second limiting plate 42 is connected to the first side plate 301 and the second side plate 302 of the volute 30, respectively.

[0147] See also Figure 17 As shown, the first limiting plate 41 and the second limiting plate 42 have the same structure. Both the first limiting plate 41 and the second limiting plate 42 are provided with a resistance portion 411 and a locking portion 412. The resistance portion 411 and the locking portion 412 are located in different planes, and a locking hole 4121 is provided on the locking portion 412.

[0148] See also Figure 4 、 Figure 12 、 Figure 15 and Figure 16 As shown, when the oil fume treatment device is in the left air outlet state, the first electromagnetic lock 23 and the second electromagnetic lock 24 are both powered off, the latches of the first electromagnetic lock 23 and the second electromagnetic lock 24 are both ejected, the abutment portion 411 of the second limiting plate 42 abuts against the second limiting seat 22, and the latch of the second electromagnetic lock 24 is inserted into the locking hole 4121 of the second limiting plate 42, so that the volute assembly can be firmly fixed and not loosened. It should be noted that in this state, the abutment portion 411 of the first limiting plate 41 does not contact the first limiting seat 21, and the latch of the first electromagnetic lock 23 is not inserted into the locking hole 4121 of the first limiting plate 41.

[0149] See also Figure 13 and Figure 14 As shown, when the oil fume treatment device is in the right air outlet state, the first electromagnetic lock 23 and the second electromagnetic lock 24 are both powered off, the latches of the first electromagnetic lock 23 and the second electromagnetic lock 24 are both ejected, the abutment portion 411 of the first limiting plate 41 abuts against the first limiting seat 21, and the latch of the first electromagnetic lock 23 is inserted into the locking hole 4121 of the first limiting plate 41, which can securely fix the volute assembly. It should be noted that in this state, the abutment portion 411 of the second limiting plate 42 does not contact the second limiting seat 22, and the latch of the second electromagnetic lock 24 is not inserted into the locking hole 4121 of the second limiting plate 42.

[0150] By energizing the first electromagnetic lock 23 and the second electromagnetic lock 24 and controlling the driving assembly by the control unit, the air outlet direction of the volute assembly can be quickly switched, thereby reducing manual intervention and improving operational efficiency.

[0151] In a possible embodiment, a detection component is provided on the smoke chamber assembly to determine whether the volute assembly is in place. This arrangement can locate the rotation angle of the volute assembly, avoid position deviation, and improve operational stability.

[0152] The detection component may be a micro switch or a photoelectric switch.

[0153] For some examples, see Figure 4 、 Figure 15 and Figure 16 As shown, the detection component can be a microswitch. The smoke chamber assembly can be provided with two microswitches, namely a first microswitch 25 and a second microswitch 26. The first microswitch 25 is mounted on the upper left plate 202 of the smoke exhaust member 20, and the second microswitch 26 is mounted on the upper right plate 203 of the smoke exhaust member 20.

[0154] When the first limit plate 41 contacts the first micro switch 25 and the first micro switch 25 is connected, it can be determined that the volute assembly is rotated into place and that the oil fume treatment device is in the right air outlet state.

[0155] When the second limit plate 42 contacts the second micro switch 26 and the second micro switch 26 is connected, it can be determined that the volute assembly has rotated into place and that the oil fume treatment device is in the left air outlet state.

[0156] In one possible embodiment, a sealing strip is provided at the edge of the volute outlet 304. This arrangement can ensure that there is no air leakage when the air outlet direction of the volute assembly is automatically reversed, thereby improving operating efficiency.

[0157] The volute outlet 304 may be in an arc shape.

[0158] For some examples, see Figure 5 and Figure 18 As shown, a first arc-shaped slot 305 and a second arc-shaped slot 306 are respectively provided on both sides of the volute outlet 304 in the Y direction. The first arc-shaped slot 305 is secured with a first sealing strip 33 , and the second arc-shaped slot 306 is secured with a second sealing strip 34 .

[0159] See also Figures 19 to 21As shown, in the arc-shaped extension direction of the volute outlet 304, a third sealing strip 35 and a fourth sealing strip 36 are provided at both ends of the volute outlet 304. The third sealing strip 35 is fixed to the surrounding plate 303 of the volute 30 through the first pressure plate 31, and the fourth sealing strip 36 is fixed to the surrounding plate 303 of the volute 30 through the second pressure plate 32.

[0160] The third sealing strip 35 and the fourth sealing strip 36 both extend along the Y direction. The third sealing strip 35 close to the volute tongue section 3030 is parallel to the circumference 303 of the volute 30 , and the fourth sealing strip 36 away from the volute tongue section 3030 is perpendicular to the tangent of the second arc section 3032 of the volute 30 .

[0161] 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 to form a continuous sealing structure to ensure that there is no air leakage when the air outlet direction of the volute assembly is automatically reversed.

[0162] The first and second pressing plates 31, 32 respectively abut against both ends of the first sealing strip 33, preventing the first sealing strip 33 from slipping out of the first arc-shaped slot 305. The first and second pressing plates 31, 32 respectively abut against both ends of the second sealing strip 34, preventing the second sealing strip 34 from slipping out of the second arc-shaped slot 306. This arrangement ensures the stability of the sealing structure.

[0163] In some examples, when the volute assembly rotates from the right air outlet state to the left air outlet state, the drive assembly drives the volute assembly to rotate along the +W direction (clockwise) to the first preset angle, the fourth sealing strip 36 at the volute outlet 304 conflicts with the upper left plate 202 of the smoke exhaust member 20, the conflicting portion 411 of the second limit plate 42 conflicts with the second limit seat 22, the pin of the second electromagnetic lock 24 is inserted into the locking hole 4121 of the second limit plate 42, the second limit plate 42 contacts the second micro switch 26, and the second micro switch 26 is connected. The second micro switch 26 can be used to determine that the volute assembly has rotated to the right position, and at the same time, it can be determined that the oil fume treatment device is in the left air outlet state. At this time, the third sealing strip 35 at the volute outlet 304 conflicts with the bottom plate 201 of the smoke exhaust member 20, so that all the oil fume discharged from the volute assembly is blown into the first smoke exhaust channel 206.

[0164] Through the coordinated design of the second limit plate 42, the second limit seat 22, the second electromagnetic lock 24 and the second micro switch 26, the rotation angle of the volute assembly in the +W direction can be accurately positioned to avoid position deviation when the oil fume treatment device is in the left air outlet state, and to achieve firm locking of the volute assembly, thereby improving operational stability and preventing position displacement due to vibration or airflow impact during operation.

[0165] When the volute assembly rotates from the left air outlet state to the right air outlet state, the driving assembly drives the volute assembly to rotate along the -W direction (counterclockwise) to the second preset angle, the volute outlet 304 is in a horizontal position, the third sealing strip 35 at the volute outlet 304 conflicts with the right upper plate 203 of the smoke exhaust part 20, the conflicting portion 411 of the first limit plate 41 conflicts with the first limit seat 21, the pin of the first electromagnetic lock 23 is inserted into the locking hole 4121 of the first limit plate 41, the first limit plate 41 contacts the first micro switch 25, the first micro switch 25 is connected, and the first micro switch 25 can be used to determine that the volute assembly has rotated to the right position, and at the same time, it can be determined that the oil fume treatment device is in the right air outlet state. At this time, the fourth sealing strip 36 at the volute outlet 304 conflicts with the bottom plate 201 of the smoke exhaust part 20, so that all the oil fume discharged from the volute assembly is blown into the second smoke exhaust channel 207.

[0166] Through the coordinated design of the first limit plate 41, the first limit seat 21, the first electromagnetic lock 23 and the first micro switch 25, the rotation angle of the volute assembly in the -W direction can be accurately positioned to avoid position deviation when the oil fume treatment device is in the right air outlet state, and to achieve firm locking of the volute assembly, thereby improving operational stability and preventing position displacement due to vibration or airflow impact during operation.

[0167] The integrated stove in the embodiment of the present invention, since it includes the oil fume treatment device in the aforementioned embodiment, can reduce the number of stock keeping units (SKUs), reduce the inventory management burden and cost pressure, and improve production efficiency and market response speed.

[0168] Among them, the integrated stove has a "+" key and a "-" key.

[0169] The control method of the integrated stove in the above embodiment is described in detail below with reference to the accompanying drawings.

[0170] See also Figure 22 As shown, an embodiment of the present invention provides a control method for an integrated stove, the control method comprising the following steps:

[0171] S100: Determine the required air outlet direction.

[0172] The desired air outlet direction can be determined according to the user's needs. When the user requires left air outlet, the desired air outlet direction is the left air outlet direction. When the user requires right air outlet, the desired air outlet direction is the right air outlet direction.

[0173] S200. When the air outlet direction of the integrated stove is inconsistent with the required air outlet direction, the driving assembly is controlled to drive the volute assembly to move so that the volute outlet 304 of the volute assembly is connected to the first air outlet 106 or the second air outlet 107 of the smoke collecting element 10.

[0174] In some examples, the integrated stove is shipped with the air outlet direction set to the left, i.e., the air outlet direction of the integrated stove is set to the left. The desired air outlet direction is set to the right. By controlling the drive assembly to drive the volute assembly to move via the control unit, the volute outlet 304 of the volute assembly can be connected to the second air outlet 107 of the smoke collector 10, thereby switching the air outlet direction of the integrated stove from the left to the right.

[0175] In other embodiments, the integrated stove is shipped with the air outlet direction set to the right, i.e., the air outlet direction of the integrated stove is set to the right. The desired air outlet direction is set to the left. By controlling the control unit to drive the volute assembly to move, the volute outlet 304 of the volute assembly can be connected to the first air outlet 106 of the smoke collector 10, thereby switching the air outlet direction of the integrated stove from the right to the left.

[0176] The control method of the integrated stove provided in an embodiment of the present invention determines the required air outlet direction. When the air outlet direction of the integrated stove is inconsistent with the required air outlet direction, the driving component is controlled to drive the volute component to move, so that the volute outlet 304 of the volute component can be connected with the first air outlet 106 or the second air outlet 107 of the smoke collecting component 10, thereby realizing automatic reversal of the air outlet direction of the integrated stove, avoiding manual disassembly operation, and thus saving time and effort.

[0177] Furthermore, the integrated stoves do not need to be differentiated into left-row and right-row models, thereby reducing the number of stock keeping units (SKUs), alleviating inventory management burdens and cost pressures, and improving production efficiency and market responsiveness. When the integrated stove's airflow direction automatically reverses, the volute assembly does not need to be manually disassembled, thus avoiding the difficulty of installing the volute outlet 304.

[0178] In one possible embodiment, the volute assembly includes a smoke exhaust piece 20, which is provided with a first smoke exhaust channel 206 connected to the first air outlet 106 of the smoke collecting piece 10 and a second smoke exhaust channel 207 connected to the second air outlet 107 of the smoke collecting piece 10, and the volute assembly is rotatably connected to the smoke exhaust piece 20.

[0179] Step S200 includes the following steps: when the air outlet direction of the integrated stove is inconsistent with the required air outlet direction, controlling the drive assembly to rotate the volute assembly so that the volute outlet 304 of the volute assembly is connected to the first smoke exhaust channel 206 or the second smoke exhaust channel 207. In this configuration, when the air outlet direction of the integrated stove is inconsistent with the required air outlet direction, controlling the drive assembly to rotate the volute assembly can connect the volute outlet 304 of the volute assembly to the first smoke exhaust channel 206 or the second smoke exhaust channel 207 of the smoke exhaust member 20, thereby achieving automatic reversal of the air outlet direction of the integrated stove.

[0180] The smoke exhaust member 20 is provided with an electric lock on both sides of the integrated stove in the longitudinal direction. In some examples, the electric lock is an electromagnetic lock. The two electromagnetic locks include a first electromagnetic lock 23 and a second electromagnetic lock 24.

[0181] The volute assembly is provided with two limiting plates, which include a first limiting plate 41 and a second limiting plate 42 .

[0182] The first electromagnetic lock 23 and the second electromagnetic lock 24 are simultaneously energized and attracted to draw the latch back into the body. There are no latches in the locking holes 4121 of the first limiting plate 41 and the locking holes 4121 of the second limiting plate 42. The volute assembly is in an unlocked state and can rotate.

[0183] The smoke exhaust member 20 is provided with a micro switch on both sides of the integrated stove in the longitudinal direction. The two micro switches include a first micro switch 25 and a second micro switch 26.

[0184] When the "left exhaust" mode is selected, the left airflow direction becomes the desired airflow direction. The microswitch away from the left airflow direction is the second microswitch 26; that is, the microswitch away from the desired airflow direction is the second microswitch 26; the electromagnetic lock away from the left airflow direction is the second electromagnetic lock 24; that is, the electromagnetic lock away from the desired airflow direction is the second electromagnetic lock 24. The microswitch toward the left airflow direction is the first microswitch 25; that is, the microswitch toward the desired airflow direction is the first microswitch 25; the electromagnetic lock toward the left airflow direction is the first electromagnetic lock 23; that is, the electromagnetic lock toward the desired airflow direction is the first electromagnetic lock 23.

[0185] When the "right exhaust" mode is selected, the right airflow direction is the desired airflow direction, and the microswitch away from the right airflow direction is the first microswitch 25, that is, the microswitch away from the desired airflow direction is the first microswitch 25; the electromagnetic lock away from the right airflow direction is the first electromagnetic lock 23, that is, the electromagnetic lock away from the desired airflow direction is the first electromagnetic lock 23. The microswitch close to the right airflow direction is the second microswitch 26, that is, the microswitch close to the desired airflow direction is the second microswitch 26; the electromagnetic lock close to the right airflow direction is the second electromagnetic lock 24, that is, the electromagnetic lock close to the desired airflow direction is the second electromagnetic lock 24.

[0186] Figure 23 This is another flow chart of the control method of the integrated stove according to an embodiment of the present application. Figure 23 is Figure 22 On this basis, further refine the operation steps.

[0187] In a possible implementation, step S100 includes:

[0188] S101. When the integrated stove is powered on and initialized, within 10 seconds, press the "+" key and the "-" key for 3 seconds to enter the left-outlet and right-outlet reversing mode.

[0189] S102. The screen of the integrated stove always displays the word "Left Row". Press the "+" or "-" key for less than 3 seconds to switch back and forth between "Right Row" and "Left Row".

[0190] Among them, after selecting a wind mode, you can enter the wind mode without any other operation within 5 seconds.

[0191] S103. If there is no other operation within 5 seconds after selecting the "left exhaust" mode, the left air outlet mode is entered.

[0192] S104: If there is no other operation within 5 seconds after selecting the "right exhaust" mode, the system enters the right air outlet mode.

[0193] It should be pointed out that the reversing mode can only be entered if the operation is performed within 10 seconds of power-on initialization. This can prevent the reversing mode from being triggered due to improper user operation during use, thereby affecting cooking.

[0194] In a possible embodiment, after step S100 and before step S200, the method further includes: controlling the two electric locks to be powered on so that the latch pins of the electric locks are disengaged from the limit plates. In this manner, the volute assembly is in an unlocked state and can rotate.

[0195] Specifically, after entering the left air outlet mode, the process proceeds to step S301a: S301a: controlling the first electromagnetic lock 23 and the second electromagnetic lock 24 to be energized.

[0196] After entering the right air outlet mode, the process proceeds to step S302a: S302a: Control the first electromagnetic lock 23 and the second electromagnetic lock 24 to be energized.

[0197] In a possible implementation, after step S301a, the method further includes:

[0198] S301b, determine whether the second micro switch 26 is connected.

[0199] When the second micro switch 26 is connected, the process proceeds to step S301c. When the second micro switch 26 is disconnected, the process proceeds to step S301d.

[0200] In some examples, S301c, determine whether the first micro switch 25 is connected.

[0201] When the first micro switch 25 is connected, the process proceeds to step S301e. When the first micro switch 25 is disconnected, that is, when the first micro switch 25 is disconnected, the process proceeds to step S301f.

[0202] It should be noted that after step S301a, when the second microswitch 26 is connected and the first microswitch 25 is disconnected, the air outlet direction of the integrated stove is consistent with the required air outlet direction, that is, the air outlet direction of the integrated stove is leftward. The first microswitch 25 and the second microswitch 26 can be used to determine whether the air outlet direction of the integrated stove is consistent with the required air outlet direction, thereby eliminating the need to rotate the volute assembly and manually determining whether the air outlet direction of the integrated stove is consistent with the required air outlet direction.

[0203] After step S301a, when the second micro switch 26 is not connected, the air outlet direction of the integrated stove is inconsistent with the required air outlet direction, that is, the air outlet direction of the integrated stove is the right air outlet direction.

[0204] In some examples, S301e triggers a reversing function failure reminder.

[0205] Among them, after a reversing function failure occurs, the reversing function of the integrated stove can be repaired, and maintenance efficiency can be improved.

[0206] It should be pointed out that after step S301a, when the second microswitch 26 is connected and the first microswitch 25 is connected, that is, when the microswitch in the air outlet direction away from the demand is connected and the microswitch in the air outlet direction close to the demand is connected, the reversing function failure reminder is triggered.

[0207] In some examples, S301f controls the first electromagnetic lock 23 and the second electromagnetic lock 24 to be powered off. This configuration allows the latch of the second electromagnetic lock 24 to be inserted into the second limiting plate 42. It is understood that the latch of the second electromagnetic lock 24 away from the left air outlet direction can be inserted into the second limiting plate 42, that is, the latch of the second electromagnetic lock 24 away from the desired air outlet direction can be inserted into the second limiting plate 42. This ensures that the volute assembly is firmly fixed and does not loosen, thereby improving the stability of the integrated stove during operation and preventing positional displacement due to vibration or airflow impact during operation.

[0208] After step S301f, the process also includes: S301g, controlling the solenoid valve to be in an open state.

[0209] When the volute outlet 304 of the volute assembly is connected to the first smoke exhaust channel 206, the solenoid valve can be controlled to be in the open state. With this configuration, the volute oil leakage hole 307 is located at the lowest point of the volute 30 in the Z direction, which serves to drain oil from the volute 30 and discharge it to the oil cup through the second oil leakage hole 2121.

[0210] After step S301g, the following further steps are included: S301h, the words "left row" on the screen continue to flash. The integrated stove has entered the "left row" mode.

[0211] The continuous flashing may be flashing at a preset time interval within a preset time period. For example, the words "Left Row" on the screen flash continuously at intervals of 1 second within 5 minutes.

[0212] In some examples, S301d, a forward current is input to the push rod motor 61. This configuration causes the volute assembly to rotate clockwise, so that the volute outlet 304 of the volute assembly can be connected to the first smoke exhaust channel 206.

[0213] The current value of the forward current input to the push rod motor 61 is a first preset value. In some examples, the first preset value may be 5A.

[0214] After step S301d, the method further includes: S301i, determining whether the current value of the push rod motor 61 exceeds a first preset value.

[0215] When the current value of the push rod motor 61 exceeds the first preset value, the process goes to step S301g.

[0216] When the current value of the push rod motor 61 does not exceed the first preset value, step S301d is continued.

[0217] In some examples, S301g, determine whether the second micro switch 26 is connected.

[0218] When the second micro switch 26 is connected, the process proceeds to step S301c.

[0219] When the "left row" mode is selected, step S200 may include: when the current value of the push rod motor 61 is greater than the first preset value and the second micro switch 26 is connected, that is, the current value of the push rod motor 61 is greater than the first preset value and the micro switch away from the required air outlet direction is connected, the abutment portion 411 of the second limit plate 42 abuts against the second limit seat 22, the second limit plate 42 contacts the second micro switch 26, the volute assembly stops rotating, and the volute assembly rotates to a preset angle, which can determine that the volute assembly has rotated into place. In this way, by dual detection of the second micro switch 26 and the current value of the push rod motor 61, it is determined that the volute assembly has rotated into place, which can improve detection reliability.

[0220] It should be noted that when the abutment portion 411 of the second limiting plate 42 abuts against the second limiting seat 22 , the resistance encountered by the volute assembly increases, so the current value of the push rod motor 61 increases, and the current value of the push rod motor 61 becomes greater than the first preset value.

[0221] When the second microswitch 26 is disconnected, the process proceeds to step S301k. When the current of the push rod motor 61 is greater than the first preset value and the second microswitch 26 is disconnected, the abutting portion 411 of the second limit plate 42 is not in contact with the second limit seat 22, the second limit plate 42 is not in contact with the second microswitch 26, and the volute assembly is not fully rotated. This may cause the volute assembly to become stuck due to foreign matter during rotation.

[0222] In some examples, S301k, trigger a first self-repair mode.

[0223] In the first self-repair mode, a reverse current is applied to the push rod motor 61 for 3 seconds, causing the volute assembly to rotate counterclockwise. After 3 seconds, a forward current is applied to the push rod motor 61, causing the volute assembly to rotate clockwise. The current values for both the reverse and forward currents are 5A.

[0224] After step S301k, the process also includes: S301m, determining whether the number of reciprocating rotations of the volute assembly exceeds 3 times.

[0225] When the volute assembly reciprocates no more than three times, that is, when the first self-repair mode is triggered no more than three times, the process proceeds to step S301i. When the volute assembly reciprocates more than three times, that is, when the first self-repair mode is triggered more than three times, the process proceeds to step S301n.

[0226] Through the first self-repair mode, the adaptability and stability of the integrated stove can be improved, and the influence of foreign interference in abnormal situations inside the integrated stove can be reduced.

[0227] In some examples, at step S301n, the first self-repair mode is exited. After step S301n, the process proceeds to step S301e.

[0228] In a possible implementation, after step S302a, the method further includes:

[0229] S302b: Determine whether the first micro switch 25 is connected.

[0230] When the first micro switch 25 is connected, the process proceeds to step S302c.

[0231] When the first micro switch 25 is not connected, the process proceeds to step S302d.

[0232] In some examples, S302c, determine whether the second micro switch 26 is connected.

[0233] When the second micro switch 26 is connected, the process proceeds to step S301e. When the second micro switch 26 is not connected, that is, when the second micro switch 26 is disconnected, the process proceeds to step S302f.

[0234] It should be noted that after step S302a, when the first microswitch 25 is connected and the second microswitch 26 is disconnected, the air outlet direction of the integrated stove is consistent with the required air outlet direction, that is, the air outlet direction of the integrated stove is the right air outlet direction.

[0235] In some examples, S301e triggers a reversing function failure reminder.

[0236] Among them, after a reversing function failure occurs, the reversing function of the integrated stove can be repaired, and maintenance efficiency can be improved.

[0237] It should be pointed out that after step S302a, when the first microswitch 25 is connected and the second microswitch 26 is connected, that is, when the microswitch in the air outlet direction away from the demand is connected and the microswitch in the air outlet direction close to the demand is connected, the reversing function failure reminder is triggered.

[0238] In some examples, S302f, the first electromagnetic lock 23, and the second electromagnetic lock 24 are powered off. This configuration allows the latch of the first electromagnetic lock 23 to be inserted into the first limit plate 41. It is understood that the latch of the first electromagnetic lock 23 away from the right air outlet direction can be inserted into the first limit plate 41, that is, the latch of the first electromagnetic lock 23 away from the desired air outlet direction can be inserted into the first limit plate 41. This ensures that the volute assembly is firmly fixed and does not loosen, improving the stability of the integrated stove during operation and preventing positional displacement due to vibration or airflow impact during operation.

[0239] After step S302f, the method further includes: S302g, controlling the solenoid valve to be in a closed state.

[0240] When the volute outlet 304 of the volute assembly is connected to the second smoke exhaust channel 207, the solenoid valve can be controlled to be in the closed state. In this configuration, the volute oil leakage hole 307 is closed, and the lowest point of the volute 30 in the Z direction is located at the volute outlet 304, which is connected to the second smoke exhaust channel 207. The oil in the volute 30 can be drained from the second oil leakage hole 2121 to the oil cup.

[0241] After step S302g, in step S302h, the words "right row" on the screen continue to flash, indicating that the integrated stove has entered the "right row" mode.

[0242] The continuous flashing may be flashing at a preset time interval within a preset time period. For example, the words "Right Row" on the screen flash continuously at intervals of 1 second within 5 minutes.

[0243] In some examples, S302d, a reverse current is input to the push rod motor 61. This configuration causes the volute assembly to rotate clockwise, so that the volute outlet 304 of the volute assembly can be connected to the second smoke exhaust channel 207.

[0244] The current value of the reverse current input to the push rod motor 61 is a second preset value. In some examples, the second preset value may be 5A.

[0245] After step S302d, the method further includes: S302i, determining whether the current value of the push rod motor 61 exceeds a second preset value.

[0246] When the current value of the push rod motor 61 exceeds the second preset value, the process goes to step S302g.

[0247] When the current value of the push rod motor 61 does not exceed the second preset value, the process continues with step S302d.

[0248] In some examples, S302g: determine whether the first micro switch 25 is connected.

[0249] When the first micro switch 25 is connected, the process proceeds to step S302c.

[0250] When the "right row" mode is selected, step S200 may include: when the current value of the push rod motor 61 is greater than the second preset value and the first micro switch 25 is connected, that is, the current value of the push rod motor 61 is greater than the second preset value and the micro switch away from the required air outlet direction is connected, the interference portion 411 of the first limit plate 41 conflicts with the first limit seat 21, the first limit plate 41 contacts the first micro switch 25, the volute assembly stops rotating, and the volute assembly rotates to a preset angle, which can determine that the volute assembly has rotated into place. In this way, by dual detection of the first micro switch 25 and the current value of the push rod motor 61, it is determined that the volute assembly has rotated into place, which can improve detection reliability.

[0251] It should be noted that when the abutment portion 411 of the first limiting plate 41 abuts against the first limiting seat 21 , the resistance encountered by the volute assembly increases, so the current value of the push rod motor 61 increases, and the current value of the push rod motor 61 becomes greater than the second preset value.

[0252] When the first microswitch 25 is disconnected, the process proceeds to step S302k. When the current of the push rod motor 61 is greater than the second preset value and the first microswitch 25 is disconnected, the abutting portion 411 of the first limit plate 41 is not in contact with the first limit seat 21, the first limit plate 41 is not in contact with the first microswitch 25, and the volute assembly is not fully rotated. This may cause the volute assembly to become stuck due to foreign matter during rotation.

[0253] In some examples, S302k, trigger a second self-repair mode.

[0254] In the second self-repair mode, a forward current is applied to the push rod motor 61 for 3 seconds, causing the volute assembly to rotate clockwise. After 3 seconds, a reverse current is applied to the push rod motor 61, causing the volute assembly to rotate counterclockwise. Both the reverse and forward currents have a current value of 5A.

[0255] After step S302k, the method further includes: S302m, determining whether the number of reciprocating rotations of the volute assembly exceeds 3 times.

[0256] Among them, when the number of reciprocating rotations of the volute assembly does not exceed 3 times, that is, when the number of times the second self-repair mode is triggered does not exceed 3 times, step S302i is entered.

[0257] When the volute assembly reciprocates more than three times, that is, when the second self-repair mode is triggered more than three times, step S302n is entered.

[0258] In some examples, at step S302n, the second self-repair mode is exited. After step S302n, the process proceeds to step S301e.

[0259] Example 2

[0260] See also Figure 24 and Figure 25 As shown, the difference between the second embodiment and the first embodiment is that: on the basis of the first embodiment, the integrated stove further includes a water inlet 71. The water inlet 71 is used to inject water into the volute 30. In some examples, the water inlet 71 can be a water inlet pipe.

[0261] The water inlet member 71 can enter the smoke collecting chamber from the bottom of the front plate 101 of the smoke collecting member, so that the water outlet end of the water inlet member 71 is arranged in the smoke collecting chamber.

[0262] A water inlet valve is provided on the water inlet member 71. When the water inlet valve is opened, water can be injected into the volute 30. When the water inlet valve is closed, water injection into the volute 30 can be stopped.

[0263] In some examples, an air inlet is provided on one side of the second side plate 302 of the volute 30. After passing through the bottom of the smoke exhaust member 20, the water inlet member 71 bends toward the air inlet and extends into the interior of the volute 30.

[0264] The bent portion of the water inlet member 71 is fixed to the smoke exhaust member 20 via a clamp 77 .

[0265] exist Figure 24 and Figure 25In the left-hand air outlet state, the fume treatment device is in the left-hand air outlet state. When the integrated stove's fume treatment device is in the left-hand air outlet state, the oil leakage hole of the volute 30 (volute oil leakage hole 307) is located at the lowest point of the volute 30 in the Z direction. At this time, the oil leakage hole of the volute 30 is located on the side of the impeller 50 near the bottom of the smoke collection chamber. The volute outlet 304 is higher than the oil leakage hole of the volute 30 in the Z direction, forming a semi-enclosed water storage area within the volute 30.

[0266] It should be pointed out that in Figure 24 The area below the dotted line L is the water storage area.

[0267] In some examples, Figure 26 In the embodiment, the air inlet of the volute 30 is provided with an air guide ring 72. The air guide ring 72 can be annular.

[0268] The inner ring of the air guide ring 72 is provided with a circular guide opening 722. The guide opening 722 is circular in shape. Along the +Z direction, the area of the guide opening 722 gradually decreases, and the air guide ring 72 can guide the airflow into the volute 30.

[0269] After the oil leakage hole of the volute 30 is closed by the on-off valve 43 and water is injected into the volute 30 by the water inlet 71, the water level in the volute 30 can rise to the lowest point of the guide opening 722 of the air guide ring 72 in the Z direction. At this time, the water in the volute reaches a predetermined height, and some blades of the impeller 50 can be immersed in the water. The inner wall of the volute 30 in the water storage area is closest to the center of the impeller 50, which can reduce water consumption and conserve resources. The impeller 50 can be cleaned by moving it within the volute 30, eliminating the need to disassemble the volute 30 and impeller 50, thereby saving time and effort.

[0270] It should be noted that when the oil fume treatment device of the integrated stove is in the right air outlet state, it is necessary to adjust the oil fume treatment device to the left air outlet state and then clean the impeller 50.

[0271] See also Figure 26 As shown, a limiting protrusion 721 is provided at the starting end of the air guide ring 72 close to the volute 30 , and a fifth sealing strip 73 is provided between the limiting protrusion 721 and the volute 30 . The fifth sealing strip 73 is in an arc shape.

[0272] The air guide ring 72 and the volute 30 can be fixedly connected by multiple bolts. The bolts can pass through the fifth sealing strip 73, so that the fifth sealing strip 73 can be fixed between the limiting protrusion 721 of the air guide ring 72 and the volute 30, and the gap between the limiting protrusion 721 and the volute 30 can be sealed, thereby preventing the water in the volute 30 from flowing out of the gap after exceeding the impeller 50.

[0273] In a possible embodiment, the integrated stove further includes a heating element 74, which is connected to the volute 30. The heating element 74 is used to heat the water in the water storage area.

[0274] In some examples, heating element 74 may be a ceramic heater.

[0275] In a possible implementation, the integrated stove further includes a liquid level detection component 75 , which is used to detect the height of water in the volute 30 .

[0276] The liquid level detection component 75 is connected to the volute 30 . In some examples, the liquid level detection component 75 may be a liquid level sensor.

[0277] A temperature sensor 76 may be provided in the volute 30 , and the temperature sensor 76 is used to detect the temperature of the water in the volute 30 .

[0278] The cleaning control method of the integrated stove in the above-mentioned embodiment 2 is described in detail below with reference to the accompanying drawings.

[0279] See also Figure 27 As shown, an embodiment of the present invention provides a cleaning control method for an integrated stove, comprising the following steps:

[0280] S410 , when the oil leakage hole of the volute 30 is located on the side of the impeller 50 close to the bottom of the smoke collecting chamber, control the switch valve 43 to close the oil leakage hole of the volute 30 .

[0281] Among them, when the oil fume treatment device of the integrated stove is in the left air outlet state, that is, when the air outlet direction of the integrated stove is the left air outlet direction, the oil leakage hole of the volute 30 is located on the side of the impeller 50 close to the bottom of the smoke collecting chamber, and the switch valve 43 is controlled to close the oil leakage hole of the volute 30.

[0282] When the oil fume treatment device of the integrated stove is in the right air outlet state, that is, when the air outlet direction of the integrated stove is the right air outlet direction, "left exhaust" is selected in the reversing mode, so that the air outlet direction of the integrated stove is the left air outlet direction, so that the oil leakage hole of the volute 30 is located on the side of the impeller 50 close to the bottom of the smoke collecting chamber, and the switch valve 43 is controlled to close the oil leakage hole of the volute 30.

[0283] S420, control the water inlet valve to open the water inlet member 71. In this way, water can be injected into the volute 30.

[0284] S430, controlling the impeller 50 to move in the volute 30. With this arrangement, the impeller 50 can be cleaned without disassembling the volute 30 and the impeller 50, thereby saving time and effort.

[0285] The impeller 50 can be driven to move by a motor.

[0286] In a possible implementation, after step S420 and before step S430, the method further includes:

[0287] The heating element 74 is controlled to heat the water in the volute 30 to a preset temperature. In this way, the impeller 50 can be cleaned by hot water, which can improve the cleaning effect.

[0288] A temperature sensor 76 is provided in the volute 30. When the water in the volute 30 is heated to a preset temperature, the heating of the water in the volute 30 is stopped.

[0289] In a possible implementation, after step S420 and before step S430, the process further includes: when the level of water in the volute 30 reaches a preset level, stopping injecting water into the volute 30 .

[0290] The liquid level detection component 75 is located in the volute 30. When the level of water in the volute 30 reaches a preset level as detected by the liquid level detection component 75, water injection into the volute 30 is stopped. This arrangement can prevent excessive water from overflowing from the air inlet of the volute 30.

[0291] In a possible implementation, step S430 includes controlling the impeller 50 to intermittently rotate in the volute 30 .

[0292] The impeller 50 can be driven by a motor to rotate intermittently. In some examples, the impeller 50 is driven by a motor to rotate for 10 seconds and then stop for 5 seconds, thereby achieving intermittent rotation of the impeller 50. This arrangement allows the impeller 50 to fully contact the water, thereby improving the cleaning effect.

[0293] Figure 28 This is another flow chart of the control method of the integrated stove according to an embodiment of the present application. Figure 28 is Figure 27 On this basis, further refine the operation steps.

[0294] In a possible implementation, before step S410, the following steps are included:

[0295] S401. When the integrated stove is powered on, press the "cleaning button" for 3 seconds to enter the cleaning confirmation mode.

[0296] S402. The screen prompts the user to "Start cleaning, please empty the oil cup in time" and prompts the user to select "Yes" or "No".

[0297] Among them, press the "+" or "-" key to switch back and forth between "Yes" and "No".

[0298] S403, select "Yes" to enter the cleaning mode.

[0299] S404: Select "No" to exit the cleaning mode.

[0300] S405 , determining whether the micro switch away from the first smoke exhaust channel 206 is connected, that is, determining whether the second micro switch 26 is connected.

[0301] The micro switch far from the first smoke exhaust channel 206 is the second micro switch 26 , and the micro switch close to the first smoke exhaust channel 206 is the first micro switch 25 .

[0302] When the micro switch away from the first smoke exhaust channel 206 is disconnected, the process proceeds to step S406a. S406a: Determine that the air outlet mode is right, and set the initial value to 1. After step S406a, the process proceeds to step S408.

[0303] When the micro switch away from the first smoke exhaust channel 206 is connected, the process proceeds to step S406b. S406b: Determine that the air outlet mode is left, and set the initial value to 0. After step S406b, the process proceeds to step S407.

[0304] In some examples, S408: power on the two electric locks. This arrangement allows the latch of the electric lock to disengage from the limit plate, and the volute assembly is in an unlocked state, allowing the volute assembly to rotate.

[0305] The electric lock is an electromagnetic lock. The two electromagnetic locks include a first electromagnetic lock 23 and a second electromagnetic lock 24.

[0306] Exemplarily, the first electromagnetic lock 23 and the second electromagnetic lock 24 are controlled to be energized.

[0307] After step S408 , the process further includes: S409 , inputting a forward current to the push rod motor 61 . This configuration causes the volute assembly to rotate clockwise, so that the volute outlet 304 of the volute assembly is connected to the first smoke exhaust channel 206 .

[0308] The current value of the forward current input to the push rod motor 61 is a first preset value. In some examples, the first preset value may be 5A.

[0309] It should be noted that, according to steps S406a, S408, and S409, prior to step 410, when the microswitch away from the first smoke exhaust channel 206 is disconnected, that is, when the oil leakage hole of the volute 30 is not located on the side of the impeller 50 near the bottom of the smoke collecting chamber, the drive assembly is controlled to drive the volute assembly to rotate. With this arrangement, when the microswitch detects that the state of the volute assembly is not the desired state, the drive assembly can adjust the state of the volute assembly so that the oil leakage hole of the volute 30 is located on the side of the impeller 50 near the bottom of the smoke collecting chamber, thereby achieving intelligent cleaning.

[0310] After step S409 , the method further includes: S409 a , determining whether the current value of the push rod motor 61 exceeds a first preset value.

[0311] When the current value of the push rod motor 61 exceeds the first preset value, the process goes to step S409b.

[0312] When the current value of the push rod motor 61 does not exceed the first preset value, step S409a is continued.

[0313] In some examples, S409b: determine whether the micro switch away from the first smoke exhaust channel 206 is connected, that is, whether the second micro switch 26 is connected.

[0314] When the micro switch away from the first smoke exhaust passage 206 is connected, the process proceeds to step S409c. When the micro switch away from the first smoke exhaust passage 206 is disconnected, the process proceeds to step S409d.

[0315] In some examples, S409d, triggering a first self-repair mode.

[0316] In the first self-repair mode, a reverse current is applied to the push rod motor 61 for 3 seconds, causing the volute assembly to rotate counterclockwise. After 3 seconds, a forward current is applied to the push rod motor 61, causing the volute assembly to rotate clockwise. Both the reverse and forward currents can be 5A.

[0317] After step S409d, the method further includes: S409e, determining whether the number of reciprocating rotations of the volute assembly exceeds 3 times.

[0318] When the volute assembly reciprocates no more than three times, that is, when the first self-repair mode is triggered no more than three times, the process proceeds to step S409a. When the volute assembly reciprocates more than three times, that is, when the first self-repair mode is triggered more than three times, the process proceeds to step S409f.

[0319] Through the first self-repair mode, the adaptability and stability of the integrated stove can be improved, and the influence of foreign interference in abnormal situations inside the integrated stove can be reduced.

[0320] In some examples, S409f triggers a reversing function failure reminder.

[0321] Among them, after a reversing function failure occurs, the reversing function of the integrated stove can be repaired, and maintenance efficiency can be improved.

[0322] In some examples, S409c controls the two electric locks to be powered off. Specifically, controlling the first electromagnetic lock 23 and the second electromagnetic lock 24 to be powered off allows the latch of the second electromagnetic lock 24 to be inserted into the second limiting plate 42, thereby firmly fixing the volute assembly.

[0323] After step S409c, the process proceeds to step S407. S407: Determine whether the micro switch near the first smoke exhaust passage 206 is connected, that is, whether the first micro switch 25 is connected.

When a cleaning function failure occurs, the cleaning function of the integrated stove can be repaired, improving maintenance efficiency.

[0325] It should be noted that, according to steps S405, S406b, S407 and S407a, before step S410, it may include triggering a cleaning function fault reminder when both micro switches are connected.

[0326] When the micro switch near the first smoke exhaust channel 206 is disconnected, the process proceeds to step S407b : controlling the switch valve 43 to close the oil leakage hole 307 of the volute.

[0327] It should be noted that in steps S405, S406b, and S407, as well as S409b, S409c, and S407b, step 410 may include controlling the on-off valve 43 to close the volute oil leakage hole 307 when the microswitch away from the first smoke exhaust channel 206 is connected and the microswitch near the first smoke exhaust channel 206 is disconnected, and the oil leakage hole of the volute 30 is located on the side of the impeller 50 near the bottom of the smoke collection chamber. This configuration allows the on-off valve 43 to be controlled by the status of the two microswitches, thereby achieving intelligent cleaning.

[0328] After step S407b, the process proceeds to step S407c. S407c: Determine whether the volute oil leakage hole 307 is closed.

[0329] In some examples, the on-off valve 43 may be a solenoid valve. The solenoid valve is equipped with a photoelectric sensor mounted on the volute 30. The photoelectric sensor detects the valve core of the solenoid valve. When the photoelectric sensor detects the valve core of the solenoid valve, it indicates that the volute oil leakage hole 307 is closed. When the photoelectric sensor does not detect the valve core of the solenoid valve, it indicates that the volute oil leakage hole 307 is not closed, that is, the volute oil leakage hole 307 is open.

[0336] After step S420b, the process proceeds to step S420c. S420c: Determine whether the water level in the volute 30 reaches a preset level.

[0337] In some examples, when the electrical signal of the liquid level detection component 75 is a high level signal (e.g., 5V), it indicates that the water level in the volute 30 has reached a preset height. When the electrical signal of the liquid level detection component 75 is a low level signal (e.g., 0V), it indicates that the water level in the volute 30 has not reached the preset height.

[0338] When the height of the water in the volute 30 does not reach the preset height, step S420 is continued.

[0339] When the water level in the volute 30 reaches a preset level, the process proceeds to step S420d. S420d: Control the water inlet valve to close the water inlet member 71.

[0343] In some examples, when the electrical signal from the temperature sensor 76 is a high level signal (e.g., 5V), it indicates that the temperature of the water in the volute 30 has reached a preset temperature. When the electrical signal from the temperature sensor 76 is a low level signal (e.g., 0V), it indicates that the temperature of the water in the volute 30 has not reached the preset temperature.

[0344] When the temperature of the water in the volute 30 does not reach the preset temperature, step S420e is continued.

[0345] When the temperature of the water in the volute 30 reaches the preset temperature, heating is stopped and step S430 is executed.

[0346] After step S430, the process proceeds to steps S431, S420f and S420b. With this arrangement, the height and temperature of the water in the volute can be adjusted in a timely manner through steps S420f and S420 during the movement of the impeller.

[0352] When the initial value is not greater than 0, that is, when the initial value is 0, the process proceeds to step S435. S435: The screen prompts "Please clean the oil cup in time."

[0353] When the initial value is greater than 0, that is, when the initial value is 1, proceed to step S436.

[0354] In some examples, S436: power on the two electric locks. This arrangement allows the latch of the electric lock to disengage from the limit plate, placing the volute assembly in an unlocked state and allowing the volute assembly to rotate.

[0355] After step S436 , the process further includes: S437 , inputting a reverse current to the push rod motor 61 . This configuration causes the volute assembly to rotate counterclockwise, so that the volute outlet 304 of the volute assembly can communicate with the second smoke exhaust channel 207 .

[0362] In some examples, S437c controls the two electric locks to be powered off. Specifically, controlling the first electromagnetic lock 23 and the second electromagnetic lock 24 to be powered off allows the latch of the first electromagnetic lock 23 to be inserted into the first limiting plate 41, thereby firmly fixing the volute assembly.
