Description

Technical Field

[0001] The present invention relates to the technical field of integrated stoves, and in particular to an integrated stove capable of distributing air volume and a control method thereof. Background Art

[0002] At present, most of the smoke exhaust methods of integrated stoves on the market are side suction and downward exhaust, that is, the smoke is collected by the machine head on the back of the stove and then discharged by the wind cabinet component integrated under the stove. Compared with traditional range hoods, the range hood part of integrated stove products is subject to more design restrictions, and the position of the air inlet is usually immutable. The main reason is that the space requirements of embedded integrated stove products force the design space of the range hood module to be very small.

[0003] In order to ensure the required air volume for users, the impeller of the integrated stove wind cabinet component is designed with a larger diameter and a higher speed during operation, but it brings about a lot of working noise and is more difficult to control than traditional range hoods. Secondly, the range hood of the integrated stove is side suction and downward exhaust, and its air inlet is closer to the source of oil smoke. It has a better suction and exhaust effect for the small amount of oil smoke generated during cooking, but the amount of oil smoke evaporated during stir-frying is large and has a large kinetic energy. The side suction and downward exhaust method has a worse smoke suction and exhaust effect than traditional European or Chinese range hoods, and is prone to smoke overflow and oil smoke that cannot be completely exhausted during stir-frying, which is harmful to health and pollutes the kitchen environment.

[0004] In addition, existing integrated stove products are mostly designed with a single fan and single air inlet solution, that is, when the fan is working, air enters both the left and right sides of the product's air inlet at the same time. When the user only uses a single-sided stove head, the air inlet on the non-working side will cause energy loss, and because the air inlet cannot be split left and right, the larger air inlet area will also cause the air flow rate on the left and right sides of the air inlet to become smaller under the premise of a fixed air volume, resulting in insufficient dynamic pressure, and the reaction result is a poor smoking effect. Summary of the invention

[0005] The present invention aims to solve at least one of the problems existing in the existing related technologies to a certain extent. To this end, the present invention proposes an integrated stove with distributed air volume, which can realize intelligent distribution of air volume and improve the problems of energy waste, low air flow rate, low dynamic pressure, poor left and right smoking effect and smoke overflow during stir-frying caused by the inability of the range hood to achieve left and right diversion when the integrated stove product is used as a single stove.

[0042] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0043] Example 1

[0044] like Figure 1-3 As shown, this embodiment provides an integrated stove capable of distributing air volume, including a stove module 1, a head assembly 2, a diversion assembly 3, a wind cabinet assembly (not shown in the figure), an identification module 4, a control module (not shown in the figure), an oil net structure 5 and a frame 6, wherein the stove module 1 is installed on the top of the frame 6, and it has two burners 11 arranged side by side on the left and right, so that the user can use a single stove or a double stove. The head assembly 2 is arranged on the top of the frame 6 and is located at the rear side of the stove module 1, and the head assembly 2 has a smoke collecting chamber (not shown in the figure), an air inlet (not shown in the figure) connected to the smoke collecting chamber, and a storage table 21 located above the air inlet, and an oil net structure 5 is provided at the air inlet.

[0045] The flow divider assembly 3 includes a flow divider 31 and a driver 32. The flow divider 31 is vertically arranged in the smoke collecting chamber and one end of which is movably connected to the head assembly 1. The flow divider 31 divides the smoke collecting chamber into a left air duct 201 and a right air duct 202. The left and right sides of the air inlet are respectively connected to the entrance of the left air duct 201 and the entrance of the right air duct 202; the driver 32 is arranged on the head assembly 2 and its output end is connected to the flow divider 31 through a swing arm 33, so that the driver 32 can push the flow divider 31 to rotate through the swing arm 33 to adjust the ventilation area of ​​the left air duct 201 and the right air duct 202. The wind cabinet assembly is arranged in the frame 6, and it selectively connects the outlet of the left air duct 201 and / or the outlet of the right air duct 202. The identification module 4 is arranged on the head assembly 2, and is used to obtain the oil fume parameters on the left and right sides of the air inlet, or to obtain the oil fume parameters of the left air duct 201 and the right air duct 202. The control module is electrically connected to the identification module 4, the driver 32 and the wind cabinet assembly respectively. The control module is used to control the working status of the wind cabinet assembly and the driver 32 according to the oil fume parameters detected by the identification module 4, and can accurately identify the use status of the two burners 11 according to the oil fume parameters.

[0046] The driver 32 of this embodiment can drive the diverter 31 to swing between a vertical position, a left position, and a right position. Figure 3 As shown, when it is identified that the burners 11 on the left and right sides are used at the same time, the driver 32 pushes the diverter 31 to a vertical position through the swing arm 33, so that the wind speed of the left air duct 201 and the right air duct 202 is stable and the wind pressure is uniform, ensuring that the smoking effect of the air inlets on the left and right sides is optimal. At this time, due to the vertical setting of the diverter 31, the turbulence of the flowing gas in the air duct can be reduced, thereby reducing the working noise.

[0047] like Figure 6 As shown, when it is identified that the left burner 11 is working and the right burner 11 is not working, the driver 32 controls the diverter 31 to rotate toward the right air duct 202, so that the diverter 31 is in a rightward position. At this time, the ventilation area of ​​the right air duct 202 is reduced and the ventilation area of ​​the left air duct 201 is increased, so that the smoking air volume on the left side of the air inlet becomes larger and the smoking air volume on the right side becomes smaller. Under the condition of a certain air volume, the air flow rate on the left side of the air inlet increases, and the dynamic pressure on the left side of the air inlet is increased, which significantly improves the smoking effect on the left side, achieves the best smoke exhaust, and effectively solves the problem of smoke overflow during stir-frying. On the contrary, if Figure 7 As shown, when it is identified that the left burner 11 is not working and the right burner 11 is working, the driver 32 controls the diverter 31 to rotate toward the left air duct 201 so that the diverter 31 is in a left position. At this time, the ventilation area of ​​the left air duct 201 is reduced and the ventilation area of ​​the right air duct 202 is increased. When the air volume is constant, the air flow rate on the right side of the air inlet is increased, which increases the dynamic pressure on the right side of the air inlet and significantly improves the smoking effect on the right side.

[0048] It can be seen that the integrated stove of the present embodiment divides the smoke collecting chamber into the left duct 201 and the right duct 202 with variable ventilation areas by adding a diversion component 3 in the smoke collecting chamber, and obtains the oil fume parameters of the left and right sides of the air inlet or the left and right ducts 201 and 202 through the identification module 4. The control module can control the working state of the driver 32 according to the obtained oil fume parameters, so as to realize the intelligent distribution of the air volume of the left and right ducts 201 and 202, thereby improving the energy waste, low air flow rate, low dynamic pressure, poor left and right smoking effect, and overflow of smoke from stir-frying caused by the inability of the range hood to realize left and right diversion when the integrated stove product is used as a single stove, thereby realizing optimal smoke exhaust and effectively solving the problem of overflow of smoke from stir-frying. In addition, by vertically arranging the diverter member 31 of the diverter assembly 3 in the smoke collecting chamber, when the diverter member 31 is in a vertical position, the wind speed of the left air duct 201 and the right air duct 202 is stable and the wind pressure is uniform, thereby ensuring that the smoking effect of the air inlets on the left and right sides is optimal, and at the same time, the turbulence of the flowing gas in the air duct can be reduced, thereby reducing the working noise.

[0049] like Figure 1-3 As shown, the head assembly 2 includes a storage table 21, a back plate 22 and a smoke shield 23. A cavity (not shown in the figure) with forward and upward openings is provided on the front of the back plate 22. The upward opening of the cavity constitutes an air inlet, and the upward opening runs through the top of the cavity, so that the smoke intake area of ​​a single air inlet is larger, which is suitable for collecting smoke from two burners 11. The smoke shield 23 is connected to the forward opening of the cavity and together defines a smoke collecting chamber. The storage table 21 is set at the upper end of the front of the back plate 22, and is used to place items and also to shield smoke to prevent oil smoke from escaping upward.

[0050] Preferably, hanging plates 231 are provided on the left and right sides of the back of the smoke baffle 23, and positioning columns are provided on the inner sides of the left and right side walls of the cavity. During installation, the hanging plates 231 are engaged with the positioning columns, and the smoke baffle 23 covers the front opening of the cavity.

[0051] like Figure 3-5 As shown, in this embodiment, the diverter 31 is a guide plate, which is vertically arranged in the middle position of the smoke collecting chamber, so that when the guide plate is in a vertical position, the ventilation areas of the left air duct 201 and the right air duct 202 are equal, and when the diverter 31 is in a vertical state, the oil droplets thereon can be drained to the wind cabinet assembly to prevent the oil smoke from being deposited on the guide plate.

[0052] Preferably, the upper end of the diverter 31 is rotatably connected to the middle of the upper end of the back of the baffle plate 23, and a slide groove 301 is provided on the side of the diverter 31 close to the swing arm 33. The slide groove 301 is arranged along the length direction of the diverter 31 and opens toward the swing arm 33. The end of the swing arm 33 away from the driver 32 is slidably connected to the slide groove 301. In this way, the driver 32 and the diverter 31 are reliably connected by transmission through the cooperation of the swing arm 33 and the slide groove 301, so as to ensure that the driver 31 can drive the diverter 31 to rotate through the swing arm 33. In addition, when the swing arm 33 drives the diverter 31 to move to a vertical position, the swing arm 33 and the slide groove 301 are also arranged vertically, so that the oil droplets attached thereto can be drained to the wind cabinet assembly to prevent the oil smoke from being deposited on the swing arm 33.

[0053] Preferably, by reasonably designing the length and width of the guide plate and controlling the rotation angle of the guide plate, the air volume of the left air duct 201 and the right air duct 202 can be accurately distributed, so that the air volume of the air duct on one side is the largest and the air volume on the other side is the smallest. The flow divider 31 of this embodiment includes a connecting section 3111, a middle section 3112 and a free section 3113 connected in sequence, the connecting section 3111 can be rotatably connected to the middle of the upper back end of the baffle plate 23, and the width of the free section 3113 is smaller than the width of the middle section 3112. In this way, by designing the width of the free section 3113 to be smaller than the width of the middle section 3112, it is beneficial to reduce the weight of the free section 3113, and it is easier to drive the free section 3113 of the flow divider 31 to swing.

[0054] More preferably, a notch 311 is provided on one side of the diverter 31 close to the swing arm 33, and the notch 311 is located between the connecting section 3111 and the driver 32, and the slide groove 301 and the swing arm 33 are both arranged at the notch 311. In this way, by adding the notch 311, installation space is reserved for the assembly of the slide groove 301 and the swing arm 33.

[0055] In this embodiment, the driver 32 is installed inside the smoke collecting chamber and connected to or close to the smoke baffle 23, so as to hide the driver 31 inside the head assembly 1 and facilitate the transmission connection between the driver 31 and the diverter 31.

[0056] In this embodiment, the diverter component 3 also includes a guide member 34, which is arranged at the notch 311 and is fastened to the diverter 31. A groove opening toward the swing arm 33 is provided on the guide member 34, and the groove constitutes a slide groove 301. In this way, by providing a groove constituting the slide groove 301 on the guide member 34, the slide groove 301 and the diverter 31 are formed into a split structure, which facilitates the processing of the slide groove 301 and helps to improve the strength of the slide groove 301.

[0057] like Figure 5As shown, preferably, two flanges 311 extending outward are integrally formed on one side of the upper end of the diverter 31 near the notch 311, and the two flanges 312 are arranged side by side and in opposite directions. The guide member 34 is fastened to the two flanges 312 by screws respectively to ensure the connection strength and firmness of the guide member 34.

[0058] In other embodiments, the slide groove 301 may be welded to the connecting section 3111 of the diverter 31 , or the slide groove 301 may be integrally formed and disposed on the connecting section 3111 of the diverter 31 .

[0059] Preferably, the flow dividing component 3 further comprises a slider 35, which is arranged at one end of the swing arm 33 away from the driver 32, and the swing arm 33 is slidably connected to the slide groove 301 through the slider 35, so that the swing arm 33 and the flow dividing member 31 are reliably slidably connected by the arrangement of the slider 35. In this embodiment, the slider 35 comprises an integrally formed connecting portion and a spherical portion, wherein the connecting portion is fastened to the end of the swing arm 33 away from the driver by screws, and the spherical portion is slidably connected to the slide groove 301.

[0060] like Figure 4-5 As shown, preferably, the diversion component 3 also includes a fixing seat 36, and the fixing seat 36 is connected to the middle of the upper end of the front side wall of the smoke collecting chamber (i.e., the back of the baffle plate 23), and an installation cavity is formed in the fixing seat 36 or between the fixing seat 36 and the front side wall of the smoke collecting chamber, and the fixing seat 36 is provided with a through hole 362 facing the swing arm 33 and connected to the installation cavity. The driver 32 is fixed in the installation cavity, and its output end passes through the through hole 362 and is connected to the swing arm 33. Therefore, by adding a fixing seat 36 and forming an installation cavity in the fixing seat 36 or between the fixing seat 36 and the front side wall of the smoke collecting chamber, it is convenient to install the driver 32, and at the same time, the driver 32 is hidden in the installation cavity, so that the driver 32 is prevented from being disturbed by oil smoke, and the performance and service life of the driver 32 are improved.

[0061] In this embodiment, the fixing seat 36 has a cavity 361 opening toward the smoke baffle 23, the fixing seat 36 is fixed to the back of the smoke baffle 23 and abuts against the smoke baffle 23, and the cavity 361 and the smoke baffle 23 jointly define a relatively sealed installation cavity, so that by designing the installation cavity to be jointly defined by the smoke baffle 23 and the cavity 361 of the fixing seat 36, the smoke baffle 23 can be fully utilized while reducing the processing material of the fixing seat 36. Of course, in other embodiments, the fixing seat 36 can be designed as two separate upper and lower parts, the upper and lower parts are connected to each other, and an installation cavity is defined between the upper and lower parts.

[0062] Preferably, a positioning portion 363 facing the diverter 31 is provided on the fixed seat 36 or the back of the smoke baffle 23 of the head assembly 2. In this embodiment, the positioning portion 363 is provided on the fixed seat 36 and is located above the mounting cavity to avoid affecting the operation of the swing arm 33 due to the setting of the positioning portion 363. One end of the diverter 31 close to the air inlet is rotatably connected to the positioning portion 363.

[0063] like Figure 2 As shown, preferably, the identification module 4 can be designed to include two oil fume parameter detection units electrically connected to the control module, and the two oil fume parameter detection units are respectively arranged in the left air duct 201 and the right air duct 202, or the two oil fume parameter detection units 41 are respectively arranged on the left and right sides of the air inlet. In this embodiment, the two oil fume parameter detection units are respectively arranged in the left air duct 201 and the right air duct 202, so that the oil fume parameters in the left air duct 201 and the right air duct 202 can be detected respectively through the two oil fume parameter detection units.

[0064] Preferably, the oil fume parameter detection unit is a temperature measurement unit or an oil fume concentration detection unit. When the oil fume parameter detection unit is a temperature measurement unit, the oil fume parameter corresponds to the oil fume temperature. When the oil fume parameter detection unit is an oil fume concentration detection unit, the oil fume parameter corresponds to the oil fume concentration. In this way, the oil fume concentrations in the left air duct 201 and the right air duct 202 can be detected respectively by two oil fume concentration detection units, so that the control module can accurately identify the working status of the two burners 11 according to the detected oil fume concentration values.

[0065] When the two burners 11 are working at the same time, the oil fume concentrations generated may be different or the same due to the different foods cooked by the two burners 11. When the oil fume concentrations generated by the two burners 11 are different, the control module can control the driver 32 to work so that the diverter 31 is slightly offset toward the side with less oil fume concentration. In this way, the dynamic pressure on the side with greater oil fume concentration can be greater through air volume distribution, which is conducive to improving the smoking effect on the side with greater oil fume concentration.

[0066] Example 2

[0067] The difference between this embodiment and the first embodiment is that the structure of the diverter 31 is different, and the connection mode between the diverter 31 and the head assembly 1 and the swing arm 33 is different, so that the movement mode of the diverter 31 is different. Figure 8-9 As shown, a transversely arranged limiting groove 203 is provided in the middle of the upper end of the front side wall of the smoke collecting chamber (i.e., the back of the smoke baffle 23), and a sliding portion 313 facing the limiting groove 203 is provided at the upper end of the diverter 31. The sliding portion 313 is slidably connected to the limiting groove 203. The driver 32 and the swing arm 33 are located below the limiting groove 203, and the end of the swing arm 33 away from the driver 32 is connected to the middle or lower end of the diverter 31.

[0068] It can be seen that by sliding the upper end of the diverter 31 to connect the middle part of the upper end of the back of the smoke baffle 23, and the middle part or the lower end of the diverter 31 is driven by the driver 32 through the swing arm 33 to rotate left and right, when the driver 32 pushes the diverter 31 to rotate left and right, the upper end of the diverter 31 can synchronously slide left and right along the length direction of the limit groove 203. In this embodiment, the sliding direction of the upper end of the diverter 31 is designed to be opposite to the rotation direction of the lower end of the diverter 31, so that when the lower end of the diverter 31 is in the left position or the right position, the unit air intake area of ​​the air duct on the side with greater air volume and dynamic pressure is reduced, which is conducive to increasing the air intake speed, but is not conducive to reducing the smoking noise.

[0069] Preferably, a transversely arranged limiting member 232 is fixedly connected to the back side of the smoke baffle 23 , and the limiting member 232 has a clamping groove arranged along the length direction thereof, and the clamping groove 3 constitutes the limiting groove 203 .

[0070] Preferably, the flow divider 31 of this embodiment includes a connecting surface 3114 and a flow divider surface 3115 connected to each other, and a sliding portion 313 is provided at the upper end of the connecting surface 3114. The fixing seat 36 is connected to the middle of the upper end of the front side wall of the smoke collecting chamber and is located below the limiting groove 203. The driver 32 is fixed in the installation cavity and its output end passes through the through hole 362 and is connected to the swing arm 33. The end of the swing arm 33 away from the driver 32 is connected to the connecting surface 3114 through a riveted shaft.

[0071] Preferably, a positioning portion 363 facing the diverter 31 is provided on the back of the fixed seat 36 or the smoke baffle 23 of the head assembly 2. In this embodiment, the positioning portion 363 is provided on the fixed seat 36 and above the mounting cavity to avoid affecting the operation of the swing arm 33 due to the setting of the positioning portion 363. A guide groove 314 is provided on the connecting surface 3114 of the diverter 31 at a position corresponding to the positioning portion 363. The guide groove 314 is arranged along the length direction of the diverter 31. The positioning portion 363 is movably inserted into the guide groove 314. In this way, the movement of the diverter 31 is better guided by the cooperation between the positioning portion 363 and the guide groove 314.

[0072] Example 3

[0073] like Fig.10As shown, the difference between this embodiment and embodiment 2 is that this embodiment omits the matching structure of the positioning portion 363 and the guide groove 314, and changes the movement mode of the diverter 31, that is, the sliding direction of the upper end of the diverter 31 is designed to be the same as the rotation direction of the lower end of the diverter 31, so that when the lower end of the diverter 31 is in the left position or the right position, when the diverter 31 moves to the left position or the right position, the upper unit air inlet area of ​​the air duct on the side with larger air volume and dynamic pressure is larger, which is beneficial to increase the smoke intake area when a single stove is used and improve the smoke collection effect.

[0074] Example 4

[0075] like Fig.11 As shown, this embodiment provides a control method for an integrated stove, which is applied to the integrated stove shown in any one of Embodiments 1-3, and the control method comprises the following steps:

[0076] S1, ignition of stove module 1;

[0077] S2, obtaining a first oil fume parameter on the left side of the air inlet or the left air duct 201, and simultaneously obtaining a second oil fume parameter on the right side of the air inlet or the right air duct 202, wherein the oil fume parameter is the oil fume temperature or the oil fume concentration;

[0078] Specifically, the first oil fume parameter on the left side of the air inlet or the left air duct 201 is obtained through the left oil fume parameter detection unit, and the second oil fume parameter on the right side of the air inlet or the right air duct 202 is obtained through the right oil fume parameter detection unit.

[0079] S3, determining whether the absolute value of the difference between the first oil fume parameter and the second oil fume parameter is greater than a preset value, if yes, proceeding to step S5, if no, proceeding to step S4;

[0080] Specifically, according to the first and second oil fume parameters obtained, the control module determines whether |first oil fume parameter-second oil fume parameter| is greater than a preset value. If |first oil fume parameter-second oil fume parameter|>preset value, it indicates that the stove module 1 is using one burner 11, that is, a single stove is used. If |first oil fume parameter-second oil fume parameter|≤preset value, it indicates that the stove module 1 is using two burners 11, that is, a double stove is used.

[0081] S4, control the flow divider 31 to be in a vertical position, and then return to step S1;

[0082] Specifically, when it is determined that the stove module 1 is using two burners 11, the diverter 31 is controlled to be in a vertical position to ensure that the wind speed in the left air duct 201 and the right air duct 202 is stable and the wind pressure is uniform, ensuring that the smoking effects of the air inlets on the left and right sides are the same and optimal. At this time, the diverter 31 is vertically arranged, which can reduce the turbulence of the flowing gas in the air duct, reduce the working noise, and avoid the deposition of oil smoke on the diverter 31.

[0083] S5, obtaining a first instantaneous oil fume parameter difference value on the left side of the air inlet or the left air duct 201, or obtaining a second instantaneous oil fume parameter difference value on the right side of the air inlet or the right air duct 202;

[0084] S6, determining whether the first instantaneous oil fume parameter difference or the second instantaneous oil fume parameter difference is greater than or equal to a reference value, if so, controlling the diverter 31 to be in a rightward position, otherwise, controlling the diverter 31 to be in a leftward position.

[0085] Specifically, when it is determined that the stove module 1 is using a single burner 11, by obtaining and analyzing the comparison result of the first instantaneous oil fume parameter difference on the left side of the air inlet or the left air duct 201 and the reference value, or obtaining and analyzing the comparison result of the second instantaneous oil fume parameter difference on the right side of the air inlet or the right air duct 202 and the reference value, it can be accurately identified whether the burner 11 on the left or the right is in use. When the first instantaneous oil fume parameter difference or the second instantaneous oil fume parameter difference is greater than or equal to the reference value, it indicates that the burner 11 on the left is in use. At this time, the diverter 31 is controlled to be in a right-biased position to make the air volume and dynamic pressure of the left air duct 201 larger, significantly improving the smoking effect on the left; conversely, the diverter 31 is controlled to be in a left-biased position to improve the smoking effect on the right.

[0086] It can be seen that the control method of this embodiment performs logical control on the driver 32 according to the different oil fume parameters generated by the two burners 11, so that the position of the diverter 31 is adapted to the working state of the two burners 11, thereby realizing the intelligent distribution of the air volume of the left air duct 201 and the right air duct 202, and improving the energy waste, low air flow rate, low dynamic pressure, poor left and right smoking effect and smoke overflow during stir-frying caused by the range hood’s inability to achieve left and right diversion when a single stove of an integrated stove is used, thereby realizing optimal smoke exhaust and effectively solving the problem of smoke overflow during stir-frying.

[0087] Preferably, before the stove module 1 is ignited, it is determined whether the working parameters of the driver 32 are equal to the preset parameters, wherein the working parameters are instantaneous current and the preset parameters are the no-load current of the driver. When the working parameters of the driver 32 are equal to the preset parameters, the diverter 31 is controlled to maintain a vertical position; when the working parameters of the driver 32 are not equal to the preset parameters, the driver 32 is controlled to work to push the diverter 31 to return to a vertical position. Therefore, by obtaining and determining whether the working parameters of the driver 32 are equal to the preset parameters before the stove module 1 is ignited, it can be ensured that the diverter 31 is in a vertical position when the stove module 1 is ignited.

[0088] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
