Description

Technical Field

[0001] This invention relates to the field of integrated stove technology, and in particular to an integrated stove smoke guiding system and device. Background Technology

[0002] Currently, the mainstream kitchen fume extraction devices on the market, namely range hoods, mainly come in three forms: top-mounted, deep-well ring-suction, and side-mounted. It is well known that the smaller the distance between the source of cooking fumes and the range hood's air intake, the higher its fume extraction rate. Traditional top-mounted range hoods are installed above the stove. Due to their structural limitations, the distance between them and the source of cooking fumes is typically 50-100cm. The negative pressure area they create is relatively far from the source of cooking fumes, making them susceptible to the influence of ambient wind and easily causing the spread of cooking fumes, polluting the indoor environment and causing discomfort. Furthermore, most stoves have two burners. When only one burner on one side is in use, it usually leads to an imbalance of fumes and smoke above the stove, resulting in a high concentration of fumes on one side and a low concentration on the other. The high-concentration fumes need to rotate at a certain angle to enter the air duct in the center of the range hood. During this process, some fumes inevitably flow away before entering the air duct, resulting in poor suction. If the suction effect is increased by increasing the air volume, the increased air volume will increase energy consumption and noise, making it inconvenient for users to use the range hood.

[0003] Given the shortcomings of existing technologies, there is an urgent need to research an integrated stove smoke guiding system and device to solve the above problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention guides the oil fumes generated by the stove in operation, preventing the oil fumes from flowing out of the range hood from the side without changing the structure of the range hood itself, thereby ensuring the range hood's suction effect and improving its suction efficiency.

[0005] This invention provides an integrated stove smoke guiding system, comprising:

[0006] The stove includes a first burner and a second burner arranged at intervals;

[0007] The air outlet system includes a first air outlet disposed on the first burner and a second air outlet disposed on the second burner.

[0008] When the first burner is in working condition and the second burner is in closed condition, the second air outlet corresponding to the second burner can discharge air at a first preset flow rate, forming a negative pressure area above the second burner to guide the oil fumes generated by the first burner toward the second burner.

[0009] When the second burner is in operation and the first burner is off, the first air outlet corresponding to the first burner can discharge air at a first preset flow rate, forming a negative pressure area above the first burner to guide the oil fumes generated by the second burner toward the first burner.

[0010] Furthermore, the first air outlet is located in the central area of ​​the first burner, and the second air outlet is located in the central area of ​​the second burner.

[0011] Furthermore, the air outlet path of the first air outlet is inclined toward the side away from the switch of the stove, and the air outlet path of the second air outlet is also inclined toward the side away from the switch of the stove.

[0012] Furthermore, the air outlet system also includes a first air outlet duct, a second air outlet duct, at least one fan, and at least one air inlet duct;

[0013] One side outlet end of the first air outlet pipe is the first air outlet, and the first air outlet is equipped with a first check valve; one side outlet end of the second air outlet pipe is the second air outlet, and the second air outlet is equipped with a second check valve.

[0014] The at least one air inlet pipe is connected to the first end of the at least one fan, and the second end of the at least one fan is connected to the first air outlet pipe and the second air outlet pipe respectively;

[0015] The at least one air inlet pipe is located away from the first burner and the second burner.

[0016] Furthermore, it also includes a detection device and controller for communication connections;

[0017] The detection device is used to determine whether a pot is present on the first burner and / or the second burner.

[0018] The controller is used for:

[0019] In response to triggering a preset smoke guiding command of the air outlet system, the working status information of the stove is obtained;

[0020] If the working status information indicates that either the first burner or the second burner is in a working state, and the other burner is in a closed state, the cookware information detected by the detection device is obtained;

[0021] If the cookware information indicates that there is no cookware on the stovetop that is in the off state, the air outlet system is controlled to enter the smoke guiding mode. The smoke guiding mode is used to allow the air outlet corresponding to the stovetop in the off state to emit air at a first preset flow rate.

[0022] Furthermore, the operating modes of the air outlet system also include an air compensation mode; the controller is also used for:

[0023] If the working status information indicates that the first burner and / or the second burner are in working status, obtain the current firepower value of the first burner and / or the second burner;

[0024] Based on a preset correspondence, a second preset flow rate corresponding to the current firepower value of the first air outlet and / or the second air outlet is determined; the preset correspondence is used to indicate the correspondence between the firepower value and the air flow rate value.

[0025] Control the air outlet system to switch to the air compensation mode so that the first air outlet and / or the second air outlet output air at the second preset flow rate.

[0026] Furthermore, the method for determining the preset correspondence includes:

[0027] Obtain the theoretical and actual firepower values ​​of each of the multiple firepower values ​​within a preset firepower value range; wherein, the theoretical firepower value is the theoretical maximum firepower value at the current firepower level, and the actual firepower value is the actual firepower value at the current firepower level.

[0028] Based on the difference between the theoretical firepower value and the actual firepower value, determine the airflow required to increase the actual firepower value to the theoretical firepower value;

[0029] Each actual firepower value is associated with and stored in relation to the airflow required for that actual firepower value, thus obtaining the preset correspondence.

[0030] Furthermore, the controller is also used for:

[0031] If the working status information indicates that the first burner and / or the second burner have switched from the working state to the off state, and there is a pot on the first burner and / or the second burner, start the timer;

[0032] If the timed duration is detected to be less than the preset duration, the air outlet system is controlled to switch to the burner cooling mode. The burner cooling mode is used to allow the first air outlet and / or the second air outlet to output air at a third preset flow rate; wherein the third preset flow rate is less than the first preset flow rate.

[0033] Furthermore, after the step of acquiring the cookware information detected by the detection device, the controller is also used to:

[0034] If the cookware information indicates that there is a cookware on the stovetop that is in the off state, clear the current preset smoke guiding command and control the air outlet system to remain in the off state or in the stovetop cooling mode.

[0035] This invention also protects an integrated stove smoke guiding device, applied to the integrated stove smoke guiding system as described above, the device comprising:

[0036] A response unit is used to respond to a preset smoke guiding command that triggers the air outlet system and obtain the working status information of the stove.

[0037] The first execution unit is configured to acquire the cookware information detected by the detection device if the working status information indicates that either the first burner or the second burner is in a working state and the other burner is in a closed state.

[0038] The second execution unit is used to control the air outlet system to enter the smoke guiding mode if the cookware information indicates that there is no cookware on the first or second burner that is in the off state. The smoke guiding mode is used to allow the air outlet corresponding to the burner in the off state to emit air at a first preset flow rate.

[0039] Implementing the embodiments of the present invention has the following beneficial effects:

[0040] In this invention, the first burner, the second burner, and the air outlet system work together to ensure that when either the first or second burner is in operation and the other burner is off, and there is no pot on the off burner, the air outlet system can be controlled to discharge air at a first preset flow rate from the air outlet corresponding to the off burner. This creates a negative pressure area above the off burner, guiding the fumes generated by the operating burner. Without altering the structure of the range hood itself, this prevents fumes from flowing out of the range hood from the side, thus ensuring the range hood's suction effect and improving its suction efficiency.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0049] Figure 1 This is a flowchart illustrating a method executed by a stove control system according to an embodiment of this application. This specification provides method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server products, the method can be executed sequentially according to the embodiments or drawings, or in parallel (e.g., in a parallel processor or multi-threaded processing environment).

[0050] See appendix Figures 1-3This embodiment provides an integrated stove smoke guiding system, including: a stove, the stove including a first burner 1 and a second burner 2 arranged at intervals; an air outlet system including a first air outlet on the first burner 1 and a second air outlet on the second burner 2; when the first burner 1 is in working state and the second burner 2 is in closed state, the second air outlet corresponding to the second burner 2 can discharge air at a first preset flow rate, forming a negative pressure area above the second burner 2 to guide the oil fumes generated by the first burner 1 toward the second burner 2; when the second burner 2 is in working state and the first burner 1 is in closed state, the first air outlet corresponding to the first burner 1 can discharge air at a first preset flow rate, forming a negative pressure area above the first burner 1 to guide the oil fumes generated by the second burner 2 toward the first burner 1.

[0051] In this embodiment, the integrated stove's smoke guiding system mainly guides the oil fumes generated on the first burner 1 and the second burner 2. Specifically, the first burner, the second burner, and the air outlet system work together to ensure that when either the first or second burner is in operation and the other burner is in a closed state, and there are no cookware on the closed burner, the air outlet system can be controlled to output air at a first preset flow rate from the air outlet corresponding to the closed burner. This creates a negative pressure area above the closed burner, guiding the oil fumes generated by the operating burner. Without altering the structure of the range hood itself, this prevents oil fumes from flowing out of the range hood from the side, thus ensuring the range hood's suction effect and improving its suction efficiency.

[0052] In this embodiment, as long as the first burner 1 and the second burner 2 are spaced apart, the first burner 1 can guide the oil fumes generated by the second burner 2, or the second burner 2 can guide the oil fumes generated by the first burner 1.

[0053] In this embodiment, the fumes generated by the stove can be processed by the range hood, and the air intake of the range hood is located in the middle of the range hood; the first burner 1 and the second burner 2 are located on both sides of the air intake; when the first burner 1 guides the second burner 2, a negative pressure area is formed above the first burner 1, and the fumes generated by the second burner 2 move towards the first burner 1 under the action of the negative pressure area. During the movement, they are drawn into the range hood by the air intake located between the first burner 1 and the second burner 2; when the second burner 2 guides the first burner 1, a negative pressure area is formed above the second burner 2, and the fumes generated by the first burner 1 move towards the second burner 2 under the action of the negative pressure area. During the movement, they are drawn into the range hood by the air intake located between the first burner 1 and the second burner 2.

[0054] In this embodiment, the negative pressure area formed by the first burner 1 is the area from the first burner 1 to the range hood, and the negative pressure area formed by the second burner 2 is the area from the second burner 2 to the range hood.

[0055] In this embodiment, the burner mentioned includes a first burner 1 and a second burner 2; the air outlet mentioned includes a first air outlet and a second air outlet.

[0056] In some possible embodiments, the first air outlet is located in the central area of ​​the first burner 1, and the second air outlet is located in the central area of ​​the second burner 2. By setting the air outlets in the central area of ​​the burner, it can be ensured that the air emanating from the air outlets acts on the burner at the optimal position, thereby achieving the best air compensation effect and the guiding effect on the fumes.

[0057] In this embodiment, the central area of ​​the stove is the area enclosed by a ring of burners.

[0058] In some possible embodiments, the air outlet path of the first air outlet is inclined toward the side away from the switch of the stove, and the air outlet path of the second air outlet is inclined toward the side away from the switch of the stove. By inclining the air outlet path toward the side away from the switch of the stove, the air outlet can be prevented from being directed toward the operator, thereby preventing the flame of the stove from being directed toward the operator, thus ensuring the safety of the integrated stove smoke guiding system.

[0059] In this embodiment, the air outlet of the first air outlet is oriented towards the side away from where the operator is standing, and the air outlet of the second air outlet is oriented towards the side away from where the operator is standing.

[0060] In some possible embodiments, the air outlet system further includes a first air outlet duct 3, a second air outlet duct 4, at least one fan 5, and at least one air inlet duct 6; one side outlet end of the first air outlet duct 3 is a first air outlet, and the first air outlet is equipped with a first check valve; one side outlet end of the second air outlet duct 4 is a second air outlet, and the second air outlet is equipped with a second check valve; at least one air inlet duct 6 is connected to the first end of at least one fan 5, and the second end of at least one fan 5 is connected to the first air outlet duct 3 and the second air outlet duct 4 respectively; at least one air inlet duct 6 is located away from the first burner 1 and the second burner 2, and by setting up mutually cooperating fans 5, air inlet duct 6, first air outlet duct 3 and second air outlet duct 4, it can be ensured that the first air outlet and the second air outlet can work independently and avoid mutual interference.

[0061] In this embodiment, the first air outlet and the second air outlet in the air outlet system are independent of each other. The air outlet system includes a first fan and a second fan. Along the direction of air flow, the first air inlet pipe, the first fan, the first air outlet 3 and the first air outlet are connected in sequence. Along the direction of air flow, the second air inlet pipe, the second fan, the second air outlet 4 and the second air outlet are connected in sequence. Both the first fan and the second fan are communicatively connected to the controller.

[0062] In this embodiment, the first check valve can prevent external air from flowing to the first air outlet duct 3, and the second check valve can prevent external air from flowing to the second air outlet duct 4.

[0063] In this embodiment, the first burner 1 and the second burner 2 are both mounted on the cooktop panel. The motor and the air inlet pipe are both mounted below the cooktop panel. The first air outlet pipe 3 protrudes through the cooktop panel and extends above the cooktop panel. That is, the first air outlet of the first air outlet pipe 3 faces the pot mounted on the first burner 1, and the second air outlet of the second air outlet pipe 4 faces the pot mounted on the second burner 2.

[0064] Specifically, the air inlet of the air inlet pipe is oriented away from the stove.

[0065] In this embodiment, the first air outlet of the first air outlet pipe 3 protrudes higher than the burner position of the first burner 1 on the stove panel, and there is a gap between the first air outlet and the pot set on the first burner 1; the second air outlet of the second air outlet pipe 4 protrudes higher than the burner position of the second burner 2 on the stove panel, and there is a gap between the second air outlet and the pot set on the second burner 2.

[0066] In some other possible embodiments, the first air outlet and the second air outlet in the air outlet system are independent of each other. When there is only one fan 5, the first air outlet and the second air outlet can work independently or work together through a control valve.

[0067] In this embodiment, both the first burner 1 and the second burner 2 include a combustion system 10 corresponding to each other. The combustion system of the first burner 1 and the combustion system of the second burner 2 are independent of each other and do not interfere with each other.

[0068] Specifically, the combustion system is located below the cooktop panel and is connected to the burner.

[0069] In some possible embodiments, a detection device and a controller for communication connections are also included;

[0070] The detection device is used to determine whether there are cookwares on the first burner 1 and / or the second burner 2;

[0071] The controller is used for:

[0072] S101: In response to the preset smoke guiding command that triggers the air outlet system, obtain the working status information of the stove;

[0073] In this embodiment, the preset smoke guiding command is a smoke guiding command issued by the operator. The smoke guiding command can be voice information, text information, or operation of the integrated stove control switch. The controller can respond to the preset smoke guiding command that triggers the air outlet system. The controller can obtain the working status information of the first burner 1 and the working status information of the second burner 2.

[0074] S102: If the working status information indicates that either the first burner 1 or the second burner 2 is in working condition, and the other burner is in off condition, obtain the cookware information detected by the detection device.

[0075] In this embodiment, if the working status information indicates that either the first burner 1 or the second burner 2 is in a working state, and the other burner is in a closed state, then the first condition for the exhaust system to operate in the smoke guiding mode is met. If there is no pot on the burner in the closed state, then the second condition for the exhaust system to operate in the smoke guiding mode is met. When the first condition for the exhaust system to operate in the smoke guiding mode is met, the pot information detected by the detection device is obtained to determine whether the second condition is met.

[0076] In this embodiment, the detection device is a contact-type in-situ detection sensor, such as a contact switch or pressure sensor, or a non-contact in-situ detection sensor, such as a distance detection sensor. The specific structure of the detection device is not limited here, as long as it can detect whether there is a pot on the stove.

[0077] Preferably, a cookware presence detection sensor 11 for acquiring cookware information is provided on the first burner 1, and a cookware presence detection sensor 11 for acquiring cookware information is provided on the second burner 2.

[0078] S103: If there is no cookware on the stove head that is in the off state according to the cookware information indicator, control the air outlet system to enter the smoke guiding mode. The smoke guiding mode is used to make the air outlet corresponding to the stove head in the off state emit air at a first preset flow rate.

[0079] In this embodiment, by coordinating the first burner 1, the second burner 2, and the air outlet system, when either the first burner 1 or the second burner 2 is in working condition and the other burner is in a closed condition, and there is no pot on the closed burner, the air outlet system can be controlled to discharge air at a first preset flow rate from the air outlet corresponding to the closed burner. This creates a negative pressure area above the closed burner, guiding the fumes generated by the working burner and preventing them from flowing out of the range hood from the side, thus ensuring the range hood's suction effect and improving its suction efficiency.

[0080] In this embodiment, if the controller determines that there is no pot on the stove in the off state based on the pot information, it determines that the air outlet system meets the second condition for entering the smoke guiding mode. At this time, the controller controls the air outlet system to enter the smoke guiding mode to guide the oil fumes generated by the stove in the working state, so as to prevent the oil fumes from flowing from the side of the range hood to the outside of the range hood, thus ensuring the suction effect of the range hood and improving the suction efficiency of the range hood.

[0081] In some possible embodiments, if the cookware information indicates that there is no cookware on the burner that is in the off state, the controller controls the air outlet system to enter the smoke guiding mode. After the step of ensuring that the air outlet corresponding to the burner in the off state emits air at a first preset flow rate in the smoke guiding mode, the controller is further configured to:

[0082] If the working status information indicates that the burner in the working state switches from the working state to the off state, the air outlet corresponding to the other burner in the off state is controlled to continuously output air at a first preset flow rate for a first preset duration.

[0083] In some possible embodiments, if the cookware information indicates that there is no cookware on the burner that is in the off state, the controller controls the air outlet system to enter the smoke guiding mode. After the step of ensuring that the air outlet corresponding to the burner in the off state emits air at a first preset flow rate in the smoke guiding mode, the controller is further configured to:

[0084] If the burner that was in the off state according to the working status information switches to the working state, the control air supply system switches from the smoke guiding state to the off state.

[0085] In some possible embodiments, the operating mode of the air supply system also includes an air compensation mode; the controller is also used to:

[0086] S105: If the working status information indicates that the first burner 1 and / or the second burner 2 are in working status, obtain the current firepower value of the first burner 1 and / or the second burner 2.

[0087] In this embodiment, the air supply system can also perform air compensation to improve the combustion efficiency of the burner and reduce combustion costs.

[0088] In this embodiment, if the working status information indicates that the first burner 1 is in working state, the air supply system can perform air compensation for the first burner 1; or if the working status information indicates that the second burner 2 is in working state, the air supply system can perform air compensation for the second burner 2; or if both the first burner 1 and the second burner 2 are in working state, the air supply system can perform air compensation for both the first burner 1 and the second burner 2 simultaneously.

[0089] S106: Determine the second preset flow rate corresponding to the current firepower value of the first air outlet and / or the second air outlet according to the preset correspondence; the preset correspondence is used to indicate the correspondence between the firepower value and the air flow rate value.

[0090] In this embodiment, a second preset flow rate corresponding to the current firepower value of the first air outlet and / or the second air outlet is determined by a preset correspondence. The fan corresponding to the first air outlet can perform air compensation for the first burner 1 with the second preset flow rate, and the fan corresponding to the second air outlet can perform air compensation for the second burner 2 with the second preset flow rate.

[0091] S107: Control the air outlet system to switch to air compensation mode so that the first air outlet and / or the second air outlet outputs air at a second preset flow rate.

[0092] In this embodiment, the corresponding second preset flow rate is determined based on the current firepower value of the burner, and then the air outlet is controlled to output air at the second preset flow rate to achieve air compensation for the burner, so that the fuel in the burner can be fully burned, the burner can achieve the optimal firepower effect, reduce the combustion cost of the burner, and improve the user experience.

[0093] In some possible embodiments, after the step of controlling the air outlet system to switch to air compensation mode so that the first air outlet and / or the second air outlet outlet emits air at a second preset flow rate, the controller is further configured to:

[0094] In response to a preset shutdown command to shut down the air supply system, the air supply system is controlled to switch from air compensation mode to the off state.

[0095] Alternatively, if the working status information indicates that the first burner 1 and / or the second burner 2 have switched from the working state to the off state, the control air supply system shall switch from the air compensation mode to the off state.

[0096] In some possible embodiments, the methods for determining the preset correspondence include:

[0097] S1061: Obtain the theoretical firepower value and actual firepower value of each of the multiple firepower values ​​within the preset firepower value range; wherein, the theoretical firepower value is the theoretical maximum firepower value at the current firepower, and the actual firepower value is the actual firepower value at the current firepower.

[0098] S1062: Determine the airflow required to increase the actual firepower value to the theoretical firepower value based on the difference between the theoretical firepower value and the actual firepower value;

[0099] S1063: Associate and store each actual firepower value with the airflow required for that actual firepower value to obtain a preset correspondence.

[0100] In this embodiment, by pre-associating and storing the actual firepower value with the airflow required for the actual firepower value, the second preset flow rate corresponding to the current firepower value can be quickly determined, thereby achieving rapid air compensation for the stove head and improving the response speed.

[0101] In some possible embodiments, the controller is also used to:

[0102] S108: If the working status information indicates that the first burner 1 and / or the second burner 2 have switched from the working state to the off state, and there are pots and pans on the first burner 1 and / or the second burner 2, start the timer;

[0103] In this embodiment, the controller can also control the air supply system to cool the cookware on the burner, so that the cookware can be cooled down quickly, avoiding burns to the operator and improving the safety of the integrated stove.

[0104] In this embodiment, the working state of the burner includes working state, off state, and just turned off state; if the first burner 1 and / or the second burner 2 switches from the working state to the off state, it indicates that the first burner 1 and / or the second burner 2 is in the just turned off state, and the timer is started at this time.

[0105] S109: If the timed duration is detected to be less than the preset duration, control the air outlet system to switch to the burner cooling mode. The burner cooling mode is used to make the first air outlet and / or the second air outlet emit air at a third preset flow rate; wherein the third preset flow rate is less than the first preset flow rate.

[0106] In this embodiment, if the controller detects that the timing duration is less than the preset duration, it controls the air outlet system to switch to the burner cooling mode and controls the burner cooling mode to carry out the preset cooling duration; it controls the first burner 1 and / or the second burner 2 to switch to the off state; by obtaining the timing duration of the burner being turned off, the cookware on the burner can be cooled when the burner is turned off, so as to achieve rapid cooling of the cookware and improve the user experience.

[0107] In some possible embodiments, if the timer duration is detected to be longer than the preset duration, it indicates that the first burner 1 and / or the second burner 2 have switched from the just-turned-off state to the turn-off state; at this time, if a preset cooling command to trigger the air outlet system is obtained to control the air outlet system to switch to the burner cooling mode, the current preset cooling command is cleared and the air outlet system is kept in the off state.

[0108] In some other possible embodiments, if the working status information indicates that the first burner 1 and / or the second burner 2 have switched from the working state to the off state, and there are no pots or pans on the first burner 1 and / or the second burner 2, the timer is not started, that is, the air outlet system is controlled to remain in the off state.

[0109] In some possible embodiments, after the step of acquiring the cookware information detected by the detection device, the controller is further configured to:

[0110] S104: If a cookware is present on a burner that is in the off state according to the cookware information indicator, the current preset smoke guiding instruction is cleared, and the air outlet system is controlled to remain in the off state or in the burner cooling mode. After the controller receives the preset smoke guiding instruction, if a cookware is present on a burner that is in the off state, the air outlet system will not enter the smoke guiding mode to prevent the cooker with a cookware from guiding the fumes to the outside of the range hood, further preventing the fumes from flowing outside the range hood and ensuring the smoke extraction effect of the range hood.

[0111] The controller of the integrated stove's smoke guiding device is used for:

[0112] S101: In response to the preset smoke guiding command that triggers the air outlet system, obtain the working status information of the stove;

[0113] S102: If the working status information indicates that either the first burner 1 or the second burner 2 is in working condition, and the other burner is in off condition, obtain the cookware information detected by the detection device.

[0114] S103: If there is no cookware on the stove head that is in the off state according to the cookware information indicator, control the air outlet system to enter the smoke guiding mode. The smoke guiding mode is used to make the air outlet corresponding to the stove head in the off state emit air at a first preset flow rate.
