Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, and in particular to a stove control method, device and system. Background Technology

[0002] Most household gas stoves on the market currently use a manually adjustable air damper. During cooking, due to varying kitchen environments, limited understanding of gas stoves, and safety concerns, most users don't actively adjust the air damper. Existing air damper adjustment mechanisms are all manual. When harmful fumes such as CO and nitrogen oxides are produced, or when backfire occurs, the size of the air damper inlet and outlet needs to be adjusted, i.e., rotated around the nozzle axis.

[0003] However, most users lack sufficient understanding of the damper structure of stoves and their adjustment angle, making it impossible for them to adjust the stove according to the concentration of harmful gases and the risk of backfire in actual situations. Summary of the Invention

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] To facilitate understanding of this embodiment, the application scenarios and design concepts of this application embodiment will be briefly introduced below.

[0057] When existing stoves produce harmful gases or pose a risk of backfire during operation, most users lack sufficient understanding of the stove's damper structure and adjustment angle, making it impossible to effectively adjust the damper according to the actual concentration of harmful gases and the risk of backfire.

[0058] Based on this, embodiments of this application provide a stove control method, device, and system.

[0059] Example 1

[0060] This application provides a stove control method, which is applied to a control unit 7 in a stove control system. The stove control system also includes a temperature sensing mechanism 1, a smoke concentration sensing mechanism 2, a motor 3, a belt drive mechanism 4, and a damper assembly 5. The temperature sensing mechanism 1 is used to detect the temperature of the central area of ​​the stove panel, and the smoke concentration sensing mechanism is used to detect the smoke concentration generated by the burner. Figure 7 As shown, the temperature sensing mechanism 1, the smoke concentration sensing mechanism 2, and the motor 3 are respectively connected to the control unit 7, and the motor 3 is connected to the damper assembly 5 through the belt drive mechanism 4.

[0061] Combination Figure 1 As shown, the method includes:

[0062] S110, obtain the first temperature value of the cooktop panel and the first concentration of harmful gas in the environment;

[0063] S120, based on the comparison relationship between the first temperature value and the preset tempering temperature threshold, and the comparison relationship between the first harmful gas concentration and the preset harmful gas concentration threshold, the motor is controlled to rotate to drive the belt drive mechanism to increase or decrease the opening angle of the damper assembly.

[0064] In this embodiment, based on the comparison between the first temperature value of the cooktop panel 81 and the first concentration of harmful gas in the environment with their respective thresholds, the motor 3 is controlled to rotate forward or backward to drive the belt drive mechanism 4 to rotate the damper assembly 5, thereby increasing or decreasing the opening angle of the damper assembly 5. In this way, the damper assembly 5 is automatically adjusted based on the temperature of the cooktop panel 81 and the concentration of harmful gas in the environment, eliminating the need for manual adjustment, resulting in a high degree of automation and improving the user experience.

[0065] In conjunction with the first aspect, step S120 specifically includes:

[0066] S121, if T1≥T0 and W1<W, control the motor to rotate in the opposite direction, drive the belt drive mechanism to rotate to reduce the opening and closing angle of the damper assembly.

[0067] In this embodiment, if the first temperature threshold T1 is greater than or equal to the preset backfire temperature threshold T0, and the first harmful gas concentration W1 is less than the preset harmful gas concentration threshold W, it indicates that the air inflow into the stove 8 is too large, causing the flame to backfire inwards, thereby increasing the temperature of the stove panel 81. In this case, the opening angle of the damper assembly 5 should be reduced to decrease the amount of air flowing to the burner 6.

[0068] S122, if T1 < T0 and W1 ≥ W, control the motor to rotate in the forward direction, drive the belt drive mechanism to rotate to increase the opening and closing angle of the damper assembly.

[0069] If the first temperature threshold T1 is less than the preset backfire temperature threshold T0, and the first harmful gas concentration W1 is greater than or equal to the preset harmful gas concentration threshold W, it indicates that the air inflow into the stove 8 is too small, resulting in incomplete combustion and overflow into the cooking environment, thereby increasing the concentration of harmful gases. In this case, the opening angle of the damper assembly 5 should be increased to increase the amount of air flowing to the burner 6.

[0070] In this embodiment, the opening and closing angle of the damper assembly 5 is achieved by the motor 3 driving the belt transmission mechanism 4 to move the main damper plate 51 and the auxiliary damper plate 52 in the damper assembly 5, thereby increasing or decreasing the opening and closing angle of the damper assembly 5.

[0071] In conjunction with the first aspect, after step S121, the method further includes:

[0072] S1311, obtain the first opening angle of the damper assembly and the second temperature value of the cooktop panel.

[0073] S1312, if T2 < T0 and A1 > A b This controls the motor to stop running.

[0074] Where T2 is the second temperature value, A1 is the first angle, and A b The first angle threshold is preset.

[0075] During the process of starting the motor 3 to drive the belt drive mechanism 4 to rotate and reduce the opening angle of the damper assembly 5 in the event of backfire, the second temperature value T2 of the cooktop panel 81 and the first angle A1 of the damper assembly are detected in real time. Based on the comparison between the second temperature value T2 and the preset backfire temperature threshold T0, and the comparison between the first angle A1 and the first angle threshold A0, the system detects the second temperature value T2 and the first angle threshold A1. b By comparing the relationship, it is determined whether the backfire phenomenon has disappeared. If the backfire phenomenon has disappeared, the control motor 3 stops running and no longer continuously reduces the opening and closing angle of the damper assembly 5.

[0076] In conjunction with the first aspect, after step S122, the following also includes:

[0077] S1321, obtain the second opening angle and the second harmful gas concentration of the damper assembly.

[0078] S1322, if W2 < W and A2 < A a This controls the motor to stop running.

[0079] Where W2 is the concentration of the second harmful gas, A2 is the second angle, and A a As a preset second angle threshold, A a >A b .

[0080] When insufficient air intake in the stove 8 leads to incomplete combustion and gas overflow, and the motor 3 is controlled to rotate forward to increase the opening angle of the damper assembly 5, the second opening angle of the damper assembly 5 and the concentration of the second harmful gas in the cooking environment are continuously monitored. When the smoke concentration in the cooking environment is effectively controlled, the motor 3 is controlled to stop running and the opening angle of the damper assembly 5 is no longer continuously increased.

[0081] Example 2

[0082] In conjunction with the first aspect, the stove control system also includes a thermoelectric generator module 9 installed on the stove burner 6, and a temperature sensing mechanism 1 is used to monitor the current temperature value of the burner. The temperature sensing mechanism 1 and the thermoelectric generator module 9 are respectively connected to the control unit 7.

[0083] Combination Figure 2 As shown, the method includes:

[0084] S210, obtain the current temperature value of the burner.

[0085] S220, determine whether the current temperature value is greater than the preset cooking temperature threshold.

[0086] If so, proceed with steps S230-S240.

[0087] S230, determines the temperature required for cooking.

[0088] S240 controls the operation of the thermoelectric power generation module to generate electricity through thermoelectricity.

[0089] In this embodiment, the current temperature value of the burner 6 is acquired in real time and compared with a preset cooking temperature threshold. When the temperature value is greater than the cooking temperature threshold, it indicates that the burner temperature has risen to meet the cooking requirements. At this time, step S240 is executed to control the thermoelectric generator module to operate, so as to generate an electromotive force through the temperature difference between the upper and lower parts of the thermoelectric generator module 9, so as to convert thermal energy into electrical energy.

[0090] As one feasible approach, the thermoelectric power generation module 9 is electrically connected to the control unit 7 (in combination with...) Figure 7 As shown), the generated electrical energy is output to the control unit 7 to power the control unit 7.

[0091] Understandably, if the result after step S220 is negative, the temperature of the burner 6 is not high enough, and the temperature difference between the heat absorbed and the heat released by the thermoelectric power generation module 9 is small. Therefore, the thermoelectric power generation module 9 will not be started at this time.

[0092] Example 3

[0093] This application provides a stove control device, which is applied to the control unit 7 in the stove control system.

[0094] Combination Figure 3 As shown, the device includes an acquisition module 10 and a control module 20.

[0095] The acquisition module 10 is used to acquire the first temperature value of the stove panel and the first concentration of harmful gas in the environment.

[0096] The control module 20 is used to control the motor to rotate based on the comparison between the first temperature value and the preset tempering temperature threshold, and the comparison between the current harmful gas concentration and the preset harmful gas concentration threshold, so as to drive the belt drive mechanism to adjust the opening and closing angle of the damper assembly.

[0097] Thirdly, this application provides a cooktop control system, including a control unit 7, which is used to perform the method described above.

[0098] Combination Figure 4 As shown, in this embodiment, the temperature sensing mechanism 1 is located on the range hood body and is used to detect the temperature of the central area of ​​the cooktop panel and the temperatures of the two burners. Alternatively, multiple temperature sensing mechanisms 1 can be provided, each corresponding to a specific area. For example, a first temperature sensing mechanism can detect the temperature of the central area of ​​the cooktop panel, a second temperature sensing mechanism can detect the temperature of the first burner, and a third temperature sensing mechanism can detect the temperature of the second burner. The aforementioned temperature sensing mechanisms can be thermocouple sensors, thermistor sensors, IC temperature sensors, etc.

[0099] Combination Figure 4 As shown, in this embodiment of the application, the smoke concentration sensing mechanism 2 is located at a position corresponding to the area where the range hood body and the burner 6 are located, and is used to detect the concentration of harmful gases in the cooking environment where the burner 6 is located.

[0100] Combination Figure 4 As shown in this embodiment, the cooktop 8 below the range hood body includes a cooktop panel 81 and a chassis 82, combined with... Figure 5 As shown, a motor 3 is installed inside the chassis 82. The output end of the motor 3 is connected to a belt drive mechanism 4. The belt drive mechanism 4 is connected to the main damper plate 51 and the auxiliary damper plate 52 in the damper assembly 5. Under the driving action of the motor 3, the belt drive mechanism 4 drives the main damper plate 51 to rotate, and the main damper plate 51 then drives the auxiliary damper plate 52 to rotate, so that the damper assembly 5 rotates relative to the bearing connected to the nozzle assembly, thereby increasing or decreasing the opening and closing angle of the damper. It can be understood that in this embodiment...

[0101] In conjunction with the third aspect, it also includes a thermoelectric power generation module 9, which specifically includes: a conductive element 91, a protective housing 92, and a mounting hole 93.

[0102] The top surface of the conductive element 91 is used to absorb heat from the stove burner, and the bottom surface is used to release heat.

[0103] A protective housing 92 is placed over the conductive element 91 and leads out a positive terminal 921 and a negative terminal 922; the positive terminal 921 and the negative terminal 922 are electrically connected to the control unit 7 respectively.

[0104] There are multiple mounting holes 93, which are opened on the protective shell 92, and the multiple mounting holes 93 are evenly distributed;

[0105] The thermoelectric power generation module 9 is fixedly installed on the burner head of the stove through the mounting hole 93 as a panel positioning plate. It generates an electromotive force based on the temperature difference between the top and bottom surfaces of the conductive element 91 and converts it into electrical energy.

[0106] In the embodiments of this application, combined with Figure 6 As shown, the thermoelectric power generation module 9 includes a ring of N / P elements. The top surface is a heat absorption surface, and the bottom surface is a heat release surface. The heat absorbed from the burner 6 is generated by the combustion on the top surface, and the temperature difference between the top surface and the bottom surface creates an electromotive force, converting thermal energy into electrical energy. This electrical energy powers the control components through the positive terminal 921 and the negative terminal 922. Simultaneously, the thermoelectric power generation module has evenly distributed mounting holes 93 in the center. These holes allow the module to be mounted on the burner head as a positioning plate for the cooktop panel 81, ensuring that the cooktop panel 81 does not shift or explode upon impact.

[0107] In conjunction with the third aspect, the end pipe of burner 6 is connected to the furnace head 61, combined with Figure 5 As shown, the burner head 61 is connected to the main nozzle 62 and the auxiliary nozzle 63. The main nozzle 62 is fitted with an interference fit first bearing 64, and the auxiliary nozzle 63 is fitted with an interference fit second bearing 65. The first bearing 64 is fitted with a main damper plate 51, and the second bearing 65 is fitted with an auxiliary damper plate 52. The main damper plate 51 can rotate around the first bearing 64, and the auxiliary damper plate 52 can rotate around the second bearing 65. The main damper plate 51 and the auxiliary damper plate 52 are connected by a first pulley 41. A motor 3 is provided on one side of the main damper plate 51, and a bushing 31 is provided at the end of the output shaft of the motor 3. An annular groove is provided on the bushing 31, and the bushing 31 is connected to the main damper plate 51 by the second pulley 42.

[0108] The bushing 31 and the main damper plate 51 and the auxiliary damper plate 52 are connected by belts for transmission. Compared with other transmission methods such as gear transmission, belt transmission is simple, can withstand lower loads, can ensure reduced system energy consumption, low noise generated by the device, and a strong user experience.

[0109] In conjunction with the third aspect, an encoder 32 is also installed inside the chassis 82. The encoder 32 is located on one side of the motor 3, and the control unit 7 is connected to the motor 3 through the encoder 32.

[0110] In this embodiment, the encoder 32 is placed on one side of the motor 3, and the control unit 7 is connected to the motor 3 through the encoder 32, which helps to improve the signal transmission rate and reduce the response time.
