Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a gas stove. Background Art

[0002] When a gas stove is in use, a large amount of smoke will be generated after the gas is burned. In the relevant calculation work of the smoke, the smoke needs to be accurately collected, so as to calculate the excess air coefficient based on the collected smoke. By timely detecting the excess air coefficient during the combustion process, it can effectively prevent too much air from mixing in, increasing heat loss and reducing thermal efficiency; at the same time, too little air mixed in will also worsen the combustion, causing environmental pollution and energy waste. For this reason, during the operation of the gas stove, it is necessary to calculate the excess air coefficient so as to take measures to automatically adjust the combustion conditions.

[0003] The premise for ensuring the accuracy of the calculation of the excess air coefficient is that the position of the gas collection device must be accurate. However, in the actual use of the gas stove, the size of the pot is uncertain, and the size of the pot directly affects the position of the gas collection device. The problem with the prior art is that the gas collection device is in a fixed position and cannot be adjusted, resulting in low accuracy in collecting smoke by the gas collection device.

The push rod 18 of the push rod motor is connected to the smoke probe, and the push rod motor drives the push rod 18 to drive the smoke probe to move horizontally to different positions in the strip opening 111 to collect smoke samples at different positions.

[0038] By providing a strip opening 111 on the panel 11 and providing a first driving device 20 transmission-connected to the gas collection device 12 under the panel 11, it is beneficial to automatically adjust the horizontal position of the gas collection device 12 in the strip opening 111 according to the size of the cookware 17, thereby facilitating the gas collection device 12 to collect more accurate smoke data, thereby improving the accuracy of smoke collection by the gas collection device 12, so that the combustion state of the gas stove 10 can be automatically adjusted according to the smoke data subsequently, so that the gas stove 10 always operates under the best combustion conditions.

Through the cooperation of the track structure 22 and the first bracket structure 19, the horizontal movement of the gas collection device 12 in the strip opening 111 can be achieved.

[0048] For example, the track structure 22 can be in the form of a slide rail or a guide rail, and can be fixed below the panel 11 by means of screws, snaps or welding. The first bracket structure 19 can be provided with a slider or a roller that matches the track structure 22, so that the first bracket structure 19 can slide or move smoothly along the track structure 22. The first driving device 20 is fixedly connected to the first bracket structure 19, and drives the first bracket structure 19 to move on the track structure 22, thereby driving the gas collection device 12 to move horizontally in the strip opening 111 to adapt to pots 17 of different sizes.

[0049] By setting a track structure 22 under the panel 11 and connecting the track structure 22 to the panel 11 and the first support structure 19 respectively, it is beneficial for the first support structure 19 to slide or move along the track structure 22, thereby facilitating the gas collection device 12 to move horizontally in the strip opening 111 to adapt to cookware 17 of different sizes, thereby improving the accuracy and adaptability of smoke collection.

For example, the track structure 22 can be a sliding rail or a guide rail fixed under the panel 11, for sliding or moving the first support structure 19 and the second support structure 23 along a specific direction.

[0053] Optionally, a second support structure 23 is provided below the panel 11, and the second support structure 23 is connected to the track structure 22, so that the second support structure 23 can slide or move along the track structure 22. The second support structure 23 can be used to support or fix other components.

[0054] For example, the second support structure 23 can be a slider or a slide seat slidably connected to the track structure 22. By sliding or moving the second support structure 23 along the track structure 22, the gas collection device 12 can be driven to move horizontally under the panel 11 to adapt to pots 17 of different sizes, thereby improving the accuracy of smoke collection and analysis.

[0055] By arranging the second support structure 23 connected to the track structure 22 under the panel 11, it is beneficial to support or fix other components.

[0056] In an exemplary embodiment, referring to Figure 1 , Figure 2 and Figure 3 The gas stove 10 also includes a second driving device 21, which is arranged below the panel 11, fixedly connected to the second support structure 23, and connected to one end of the gas collection device 12.

[0060] For example, the controller 15 can calculate the vertical distance that the gas collection device 12 needs to move according to the preset control strategy, and convert the distance into a control signal and send it to the second driving device 21. After receiving the control signal, the second driving device 21 can drive the gas collection device 12 connected to the output end of the second driving device 21 to move vertically along the strip opening 111 by a corresponding distance, thereby ensuring that the gas collection device 12 can accurately collect the flue gas generated by the combustion of the gas.

[0061] By arranging a second driving device 21 under the panel 11 and fixing the second driving device 21 to the second support structure 23 and connecting it to one end of the gas collection device 12 at the same time, it is beneficial to drive the gas collection device 12 to move vertically in the strip opening 111, so as to automatically adjust the height position of the gas collection device 12 according to the change of the size of the pot 17, thereby ensuring that the gas collection device 12 can accurately collect the smoke generated by the combustion of the gas, thereby improving the intelligence level of the gas stove 10.

[0062] In an exemplary embodiment, referring to Figure 1 , Figure 2 and Figure 3 The gas stove 10 also includes: a gas detection device, which is arranged below the panel 11 and connected to the gas collection device 12, and is used to detect smoke information in the smoke; a controller 15, which is respectively communicated with the first drive device 20, the second drive device 21 in the gas stove 10 and the gas detection device.

[0064] Among them, the gas collection device 12 can guide the collected flue gas to the gas detection device for detection.

[0065] The controller 15 may be a control unit for receiving smoke information detected by the gas detection device and controlling the actions of the first drive device 20 and the second drive device 21 according to the smoke information. For example, the controller 15 may be a main control chip or a single chip microcomputer of the gas stove 10 .

[0066] Optionally, when the gas stove 10 is working, the gas collection device 12 collects the smoke generated by the combustion of the gas, and guides the smoke to a gas detection device disposed under the panel 11 of the gas stove 10 and connected to the gas collection device 12 for detection. The gas detection device detects smoke information in the smoke, and sends the detected smoke information to a controller 15 that is communicatively connected to the gas detection device. The controller 15 controls the actions of the first drive device 20 and the second drive device 21 that are communicatively connected to the controller 15 according to the received smoke information, thereby causing the gas collection device 12 to move horizontally and vertically.

[0067] For example, when the gas stove 10 is ignited, the flue gas probe provided under the panel 11 of the gas stove 10 begins to collect the flue gas generated by the combustion of the gas, and guides the flue gas to the oxygen sensor connected to the flue gas probe for detection. The oxygen sensor detects the oxygen content information in the flue gas, and sends the detected oxygen content information to the main control chip of the gas stove 10 that is communicatively connected to the oxygen sensor. The main control chip calculates the value of the excess air coefficient α based on the received oxygen content information. When the value of the excess air coefficient α is not within the set range (such as the range between 1.3 and 1.8), the main control chip controls the action of the first push rod motor and the second push rod motor that are communicatively connected to it. The first push rod motor drives the flue gas probe connected to it to move horizontally, and the second push rod motor drives the flue gas probe connected to it to move vertically until the value of the excess air coefficient α is within the set range.

[0068] By setting up a gas detection device to detect smoke information and sending the detection result to the controller 15, the controller 15 controls the first drive device 20 and the second drive device 21 to adjust the position of the gas collection device 12 according to the smoke information, which is beneficial to adjust the position of the gas collection device 12 in real time according to the actual combustion situation, thereby facilitating the improvement of the accuracy of smoke collection, and further achieving precise control of the combustion state, thereby improving the combustion efficiency of the gas stove 10.

[0069] In an exemplary embodiment, referring to Figure 1 , Figure 2 and Figure 3 The gas detection device includes: an air pump 29 , which is arranged below the panel 11 and connected to the gas collection device 12 ; an oxygen content sensor 28 , which is arranged below the panel 11 and connected to the air pump 29 .

[0070] Among them, the vacuum pump 29 can be a device for extracting and transporting gas. For example, the vacuum pump 29 can be arranged under the panel 11 of the gas stove 10, connected to the gas collection device 12 for collecting flue gas, and used to extract the flue gas collected by the gas collection device 12 and transport it to the oxygen content sensor 28.

[0071] Among them, the oxygen content sensor 28 can be a device for detecting the oxygen content in the gas. For example, the oxygen content sensor 28 can be arranged under the panel 11 of the gas stove 10 and connected to the vacuum pump 29 through a pipeline to detect the oxygen content in the flue gas transported by the vacuum pump 29.

[0072] Optionally, after the gas collection device 12 collects the flue gas generated by the combustion of the gas, the flue gas is transported to the exhaust pump 29 provided below the panel 11 of the gas stove 10. The exhaust pump 29 extracts the flue gas collected by the gas collection device 12 and transports it to the oxygen content sensor 28 provided below the panel 11 of the gas stove 10. The oxygen content sensor 28 detects the flue gas transported by the exhaust pump 29 to obtain information on the oxygen content in the flue gas.

[0073] For example, after the gas collection device 12 collects the flue gas generated by the combustion of the gas, it transmits the flue gas to the exhaust pump 29 through a pipeline. The exhaust pump 29 extracts the flue gas collected by the gas collection device 12 through suction, and transmits the extracted flue gas to the oxygen content sensor 28 through another pipeline. The oxygen content sensor 28 analyzes the flue gas transmitted by the exhaust pump 29 to obtain oxygen content information such as the volume fraction or mass fraction of oxygen in the flue gas.

[0074] By providing an exhaust pump 29 and an oxygen content sensor 28, the exhaust pump 29 extracts the flue gas collected by the gas collection device 12 and transmits it to the oxygen content sensor 28, which is beneficial for the oxygen content sensor 28 to accurately detect the oxygen content in the flue gas, thereby facilitating the gas stove 10 to accurately adjust the combustion state according to the detected oxygen content and improve the combustion efficiency.

[0075] In an exemplary embodiment, referring to Figure 1 , Figure 2 and Figure 4 The gas stove 10 also includes a damper adjustment device, which is arranged below the panel 11 and is used to adjust the air intake of the damper structure of the burner 24 in the gas stove 10.

[0077] The burner 24 may be a device for burning gas in the gas stove 10 , and the burner 24 may be connected to the stopcock 27 and the pulse igniter 30 respectively.

[0078] The damper structure may be a structure in the burner 24 for adjusting the amount of air intake. For example, the damper structure may be an adjustable door-shaped structure at the air inlet of the burner 24 for adjusting the amount of air intake.

[0079] The air intake of the air door structure of the burner 24 is regulated by providing an air door regulating device, which is helpful to ensure that the gas stove 10 always operates under the best combustion condition.

[0080] In an exemplary embodiment, referring to Figure 1 , Figure 2 and Figure 4The gas stove 10 also includes: a third driving device 26, which is arranged below the panel 11, is communicated with the controller 15, and is connected to the air door adjustment device; a third bracket structure 31, which is arranged below the panel 11 and is fixedly connected to the panel 11 and the third driving device 26 respectively.

[0081] Among them, the third driving device 26 can be a device for driving the damper adjustment device to adjust the air intake volume of the damper structure of the burner 24. For example, the third driving device 26 can be a stepper motor, which drives the damper gear piece 25 to rotate through the stepper motor, thereby adjusting the opening of the damper structure.

[0082] The controller 15 may calculate the excess air ratio α according to the data detected by the oxygen sensor, and send a control signal to the third drive device 26 .

[0083] Among them, the damper adjustment device can be a device for adjusting the air intake amount of the burner 24. For example, the damper adjustment device can include a damper gear piece 25, a damper spring 32, etc., and the opening of the damper structure is adjusted by changing the rotation angle of the damper gear piece 25.

[0084] The third support structure 31 may be a support for supporting and fixing the third driving device 26 , for example, the third support structure 31 may be a stepping motor support.

[0085] Optionally, after receiving the oxygen content data in the flue gas detected by the oxygen sensor, the controller 15 calculates the value of the excess air coefficient α, and then compares the value with the preset range of the excess air coefficient α. If it is not within the preset range of the excess air coefficient α, the controller 15 sends a control signal to the third drive device 26. After receiving the control signal, the third drive device 26 drives the damper adjustment device to adjust the opening of the damper structure of the burner 24, thereby adjusting the air intake of the burner 24, so that the excess air coefficient α is maintained within the preset range of the excess air coefficient α.

[0086] For example, when the controller 15 calculates that the excess air coefficient α is less than 1.3, the controller 15 sends a control signal to open the air door to the third drive device 26. After receiving the signal, the third drive device 26 drives the air door adjustment device (such as the air door gear piece 25) to rotate by its own rotation. The air door gear piece 25 rotates a certain angle, so that the opening of the air door structure of the burner 24 increases, and the air intake of the burner 24 increases until the excess air coefficient α reaches the optimal range of 1.3 to 1.8. In this process, the third bracket structure 31 plays a role in supporting and fixing the third drive device 26.

[0087] By setting up the third driving device 26 and the third support structure 31, the third driving device 26 drives the damper adjustment device to adjust the damper opening of the burner 24 under the control of the controller 15, which is beneficial to automatically adjust the air intake volume of the burner 24 according to the calculated value of the excess air coefficient, thereby facilitating the gas stove 10 to always operate in the optimal combustion state and improve the combustion efficiency.

[0088] In an exemplary embodiment, referring to Figure 1 , Figure 2 and Figure 4 The third driving device 26 is provided with a gear structure 261; the damper adjusting device includes a damper gear piece 25 and a damper spring 32; the damper gear piece 25 is respectively connected to the damper structure and the gear structure 261 of the burner 24, and is respectively fixedly connected to the damper spring 32 and the nozzle 33 in the gas stove 10.

[0089] The gear structure 261 may be a gear on the third driving device 26 for driving the damper gear piece 25 to rotate. For example, the gear structure 261 may be a gear located at the head of the stepping motor.

[0090] Among them, the damper gear piece 25 can be a gear piece in the damper adjustment device for adjusting the opening of the damper structure of the burner 24. For example, the damper gear piece 25 can be a gear piece installed at the air inlet of the burner 24, one end of which is connected to the gear structure 261 of the third drive device 26, and the other end is fixedly connected to the damper spring 32 and the nozzle 33 in the gas stove 10.

[0091] Among them, the damper spring 32 can be an elastic part in the damper adjustment device for fixing the damper gear piece 25. For example, the damper spring 32 can be a spring installed at the air inlet of the burner 24 and used to fix the damper gear piece 25 on the nozzle 33 of the gas stove 10.

[0092] Among them, the damper structure of the burner 24 can be a structure at the air inlet of the burner 24 for adjusting the air intake amount. For example, the damper structure of the burner 24 can be an air inlet baffle structure that cooperates with the damper gear piece 25.

[0093] The nozzle 33 in the gas stove 10 may be a component on the gas stove 10 for spraying gas. For example, the nozzle 33 in the gas stove 10 may be a gas nozzle 33 installed on the burner 24 .

[0094] Optionally, after receiving the signal from the controller 15, the third driving device 26 starts to rotate according to the analyzed data. The pinion gear at the head of the third driving device 26 rotates accordingly, driving the damper gear piece 25 connected thereto to rotate. When the damper gear piece 25 rotates, one end cooperates with the damper structure of the burner 24 to adjust the opening of the damper structure, thereby changing the air intake of the burner 24; the other end is fixedly connected to the nozzle 33 in the gas stove 10 through the damper spring 32, so that the damper gear piece 25 can remain stable while rotating.

[0095] The damper gear piece 25 is respectively connected to the damper structure of the burner 24 and the gear structure 261 of the third drive device 26, and is fixedly connected to the damper spring 32 and the nozzle 33 of the gas stove 10, which is beneficial for the third drive device 26 to accurately adjust the damper opening, while ensuring the stability of the adjustment process of the damper gear piece 25, thereby facilitating the automatic optimization control of the excess air coefficient during the combustion process of the gas stove 10.

[0096] In an exemplary embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the gas stove 10 includes the following three parts:

[0097] (1) Automatic adjustment mechanism of flue gas probe:

[0098] Description of mechanism composition: This mechanism is mainly composed of a flue gas probe (gas collection device 12), a probe housing (gas collection device housing 13), a preset track (track structure 22), a first push rod motor (first drive device 20), a second push rod motor (second drive device 21), a motor bracket (first bracket structure 19 and second bracket structure 23), a motor push rod (push rod 18), etc.

[0099] Assembly position description: the track (track structure 22) is installed at a preset position on the bottom surface of the stove panel 11 (panel 11); the probe housing is covered over the flue gas probe; the first motor bracket (first bracket structure 19) is horizontally installed at a preset position on the bottom surface of the stove panel 11, and then the first push rod motor is installed in the first motor bracket, and the push rod 18 is installed in the first push rod motor; the second push rod motor is vertically installed in the second motor bracket (second bracket structure 23), and then the second motor bracket is installed in the track.

[0100] Movement principle: After the first push rod motor receives the signal, the first push rod motor moves in the vertical direction after the processor calculates the displacement value; after the second push rod motor receives the signal, the second push rod motor moves in the horizontal direction after the processor calculates the displacement value.

[0101] (2) Automatic damper adjustment mechanism:

[0102] Description of the mechanism composition: This mechanism is mainly composed of a stepper motor (third driving device 26), a stepper motor bracket (third bracket structure 31), a damper gear piece 25, a damper spring 32, etc.

[0103] Assembly position description: The damper gear piece 25 is installed at the air inlet of the burner 24 and is fixed by the nozzle 33 and the damper spring 32; the stepper motor is installed in the stepper motor bracket, and the stepper motor bracket is installed in the fixed position of the burner 24.

[0104] Rotation principle: After the stepper motor receives the signal from the data processor, it starts to rotate according to the analyzed data, and the small gear (gear structure 261) located at the head of the stepper motor can drive the damper gear piece 25 to start rotating, thereby realizing the automatic adjustment function of the air intake at the damper.

[0105] (3) Electronic control and data processing module:

[0106] It is mainly composed of a display screen, an oxygen sensor (oxygen content sensor 28), and a data processor (controller 15).

[0107] The formula for calculating the excess air coefficient α is: α=21 / (21-O2´).

[0108] The O2´ value is provided by the oxygen sensor, and the excess air coefficient α is controlled between 1.3 and 1.8. Based on this, the excess air coefficient α can be calculated by simply reading the O2´ value. In addition, if the oxygen content exceeds 14%, the flue gas probe needs to be moved up and down, and then automatically adjusted according to the set range.

[0109] By automatically adjusting the position of the smoke probe according to the size of the pot 17, the detection data can be made more accurate and reliable; during the use of the gas stove 10, the excess air coefficient α can be continuously monitored, and the collected data is analyzed and processed in the main chip, and then the excess air coefficient α automatic adjustment device is used to make corresponding adjustments, so that the gas stove 10 always works in the best combustion conditions.
