Description

Technical Field

[0001] A stove, especially a stove with automatic fire control. Background Art

[0002] Food is the paramount necessity of the people, and cooking is the first step in dealing with food. Being able to cook delicious food for people to enjoy is a blessing to the world. However, the way of using fire for cooking depends on people, and not everyone is an experienced cook. For example, current gas stoves rely on people to manually control the knob of the gas stove to control the supply amount of gas to adjust the heat of the gas stove. However, for novice cooks, it is difficult to accurately control the size of the heat and the length of the fire output time, so novice cooks are prone to burning or undercooking the ingredients, which not only affects the taste of the food but also causes waste of ingredients or cooking time. Summary of the Utility Model

[0003] In view of the above problems, the present utility model provides a stove with automatic fire control, which can automatically control the fire for cooking food, thereby accurately mastering the heat of the gas stove and the length of the fire output time to assist in cooking food of high quality and avoiding waste of ingredients or cooking time caused by improper control of the heat of the gas stove.

[0004] The stove with automatic fire control of the present utility model includes:

[0005] A gas stove having a stove base pipeline and an electronic igniter;

[0006] An electronically controlled gas valve connected to the stove base pipeline for connecting a gas input source and controlling a gas flow rate of the gas input source to input a gas into the stove base pipeline according to a valve opening degree;

[0007] A control circuit electrically connected to the electronically controlled gas valve.

[0008] The control circuit of the present utility model can control the state of a fire generated by the gas stove according to a control script. By controlling the gas flow rate into the gas stove with the electronically controlled gas valve, it can control the gas flow rate more precisely than manually turning the knob, and thus more precisely control the heat of the gas stove. For example, when the control circuit controls the gas valve to have a large opening and controls the electronic igniter to ignite and generate a spark according to the control script, it controls the gas stove to generate a large fire. When the control circuit controls the gas valve to have a small opening and controls the electronic igniter to ignite and generate a spark according to the control script, it controls the gas stove to generate a small fire. When the control circuit controls the gas valve to be completely closed and controls the electronic igniter not to ignite and no spark is generated according to the control script, it controls the gas stove to stop generating the fire. In this way, the control script has planned the heat and the duration of the fire generated by the gas stove, and the control circuit controls the fire according to the control script.

[0036] Please refer to Figure 1 As shown, the present utility model provides a stove 1 for automatically controlling the firepower, which includes a control circuit 10, a gas stove 20 and an electric control gas valve 30.

[0037] The gas stove 20 has a stove base pipeline 21 and an electronic igniter 22, and the control circuit 10 is electrically connected to the electronic igniter 22 and the electric control gas valve 30 of the gas stove 20 respectively. The electric control gas valve 30 is connected to the stove base pipeline 21 of the gas stove 20, and the electric control gas valve 30 is for connecting a gas input source 2. Thus, the electric control gas valve 30 controls a gas flow rate of the gas input source 2 inputting a gas to the stove base pipeline 21 according to a valve opening degree. When the valve opening degree is fully open, the gas flow rate is maximized, and when the valve opening degree is closed, the gas flow rate is zero.

[0038] The control circuit 10 of the present utility model controls the valve opening degree of the electric control gas valve 30 and an ignition state of the electronic igniter 22 according to a control script.

[0039] For example, in an embodiment, the valve opening degree of the electric control gas valve 30 may have states such as closed, low fire, high fire, etc., and the ignition state of the electronic igniter 22 has a state of generating sparks during ignition and a state of not generating sparks without ignition. For the electronic igniter 22, the so-called sparks generated by the ignition state are an electric arc generated by the discharge between a first electrode E1 and a second electrode E2 of the electronic igniter 22 due to a high potential difference.

[0040] When the valve opening of the electronically controlled gas valve 30 is closed and the electronic igniter 22 is in a state of not generating a spark, the gas stove 20 is in a state of stopping gas supply and extinguishing the fire.

[0041] When the valve opening of the electronically controlled gas valve 30 is in the small-fire state and the electronic igniter 22 is in a state of generating a spark, the gas stove 20 is ignited and presents a small-fire state.

[0042] When the valve opening of the electronically controlled gas valve 30 is in the large-fire state, the gas stove 20 presents a large-fire state.

[0043] In other embodiments, the valve opening of the electronically controlled gas valve 30 can further have more opening states. For example, a medium-fire state is further provided between the small-fire and large-fire states. According to the above logic, when the valve opening of the electronically controlled gas valve 30 is in the medium-fire state, the gas stove 20 presents a medium-fire state.

[0044] The key point of the present utility model is that the control script executed by the control circuit 10 can be pre-programmed to plan the cooking intensity (such as extinguishing the fire, small fire, large fire, etc.) and the length of the fire output time of the gas stove 20. And the control circuit 10 can automatically control the fire 40 according to the control script to assist the user of the present utility model to control the fire properly and cook delicious dishes.

[0045] In one embodiment, the control script includes a small-fire setting, a large-fire setting, a fire-extinguishing setting, and at least one schedule. When the control circuit 10 controls the valve opening of the electronically controlled gas valve 30 and the ignition state of the electronic igniter 22 according to the control script, the control circuit 10 determines when to use the small-fire setting, the large-fire setting, or the fire-extinguishing setting to control the valve opening of the electronically controlled gas valve 30 and the ignition state of the electronic igniter 22 according to each schedule.

[0046] For example, in one embodiment, the control script includes a fried-rice schedule and a fried-egg schedule. The user can first edit the control script to set whether to execute the fried-rice schedule or the fried-egg schedule first, or only execute one of them. In other words, the user can freely use their creativity or cooking skills to program the content of the control script. In this example, the fried-egg schedule can be as shown in Table 1 below:

[0047]

[0048] Table 1

[0049] The present utility model does not limit the manner in which the control script programs the at least one schedule. In this example, the control circuit 10 starts timing from zero for one second count. When the second count is between 0 and 5 seconds, the control circuit 10 uses the high-fire setting to control the gas valve opening and the ignition state, so that the gas stove 20 starts frying eggs with a larger fire. When the second count is between 5 and 20 seconds, the control circuit 10 uses the low-fire setting to control the gas valve opening and the ignition state, so that the gas stove 20 slowly fries eggs with a smaller fire. And when the second count is equal to 20 seconds, the control circuit 10 uses the fire-off setting to control the gas valve opening and the ignition state, so that the gas stove 20 stops firing.

[0050] In addition, as Figure 1 shown, in this embodiment, the stove 1 is further provided with a communicator 50, an exhaust fan 60, a camera 70, a stop button 80 and a transformer 90. The control circuit 10 is also electrically connected to the communicator 50, the exhaust fan 60, the camera 70, the stop button 80 and the transformer 90 respectively.

[0051] The communicator 50 is for connecting and cooperating with an external control device 3 of the present case. The control circuit 10 receives the control script provided by the external control device 3 through the communicator 50, and the control circuit 10 executes the control script provided by the external control device 3. Specifically, the communicator 50 can be a wired or wireless network module. For example, the communicator 50 can be a digital modular remote I / O of model ADAM-6024. Thus, the communicator 50 is connected to a network to connect to the external control device 3 through the network. And, the control circuit 10 can receive the remote control from the external control device 3 through the communicator 50. When the control circuit 10 receives a remote control signal generated by the external control device 3 through the communicator 50, the control circuit 10 controls the gas valve opening of the electronically controlled gas valve 30 and the ignition state of the electronic igniter 22 according to the remote control signal. In this embodiment, when the control circuit 10 receives the remote control signal while executing the control script, the control circuit 10 will stop executing the control script and give priority to executing the remote control of the external control device 3.

[0052] The present utility model does not limit the form and installation position of the exhaust fan 60. The exhaust fan 60 is aligned with the gas stove 20 to effectively extract oil fumes. When the control circuit 10 controls the gas stove 20 to generate the fire 40 according to the control script, it should represent that cooking has started. Therefore, the control circuit 10 will start to control the exhaust fan 60 to rotate to extract oil fumes.

[0053] The transformer 90 of the present utility model is power - connected to a power source 4 to convert a high - voltage alternating current received by the transformer 90 from the power source 4 into a low - voltage direct current, and the transformer 90 outputs the low - voltage direct current to the control circuit 10 as the power supply required for the operation of the control circuit 10. In this embodiment, the high - voltage alternating current can be the 220 - volt mains power, and the low - voltage direct current can be 12 - volt direct current. The transformer 90 is used for voltage transformation and conversion from 220 - volt alternating current to 12 - volt direct current.

[0054] Please refer to Figure 2 and Figure 3 as well. In this embodiment, the stove 1 of the present utility model is disposed on a table 5. A gas stove 20 is provided on the table 5, and a control box 6 is provided on one side of the table 5. The control circuit 10, the communicator 50, and the transformer 90 are provided inside the control box 6, and a stop button 80 is provided on the surface of the control box 6 for the user to press when they want to urgently stop the gas stove 20 from generating the fire 40. When the stop button is pressed to generate a stop signal to the control circuit 10, the control circuit 10 controls the valve opening of the electric control gas valve 30 to close, and the control circuit 10 controls the electronic igniter 22 to stop igniting. Specifically, when the control circuit 10 receives the stop signal, regardless of whether the control circuit 10 is executing the control script or receiving the remote control signal, the control circuit 10 will preferentially close the valve opening of the electric control gas valve 30 and stop the electronic igniter 22 from igniting according to the stop signal to stop the fire immediately and ensure safety without worry.

[0055] In this embodiment, a bracket 71 is fixed to the table 5, and the camera 70 is mounted on the table 5 by the bracket 71. The camera 70 faces the gas stove 20 to take a video signal, and the camera 70 outputs the video signal to the processor 10. The control circuit 10 receives the video signal from the camera, and the control circuit 10 outputs the video signal to the external control device 3 through the communicator 50. Thus, the external control device 3 can monitor the actual situation of the gas stove 20 firing through the streaming of the video signal to facilitate remotely controlling the operation of the gas stove 20 when necessary.

[0056] In addition, an electric control gas valve 30 and a pipeline connecting the gas input source 2 and the gas stove 20 through the electric control gas valve 30 are provided on the other side of the table 5. In this embodiment, the electric control gas valve 30 uses a compact motorized rotary actuator to adjust the valve opening of the electric control gas valve 30 according to a control signal output by the processor 10 (according to the control script).

[0057] Please refer to Figure 1 and Figure 4 , the gas stove 20 of the present utility model further has a fire detector 23. The fire detector 23 is electrically connected to the control circuit 10, and the fire detector 23 generates a fire detection signal to the control circuit 10. When the control circuit 10 desires to control the gas stove 20 to generate the fire 40 according to the control script, or desires to control the gas stove 20 to generate the fire 40 according to the remote control signal, however, at the same time, when the control circuit 10 determines that the gas stove 20 does not actually generate the fire 40 according to the fire detection signal, the control circuit 10 controls the electronic igniter 22 to ignite and generate a spark, so that the gas stove 20 can surely generate the fire 40. For example, during the cooking process, the fire 40 may sometimes be extinguished due to external environment, such as wind blowing, resulting in the fire 40 being extinguished under unexpected conditions. At this time, the fire detector 23 will detect the extinguishment of the fire 40, and the processor 10 will determine that the fire 40 of the gas stove 20 has been extinguished according to the fire detection signal. But at this time, the electronically controlled gas valve 30 is still in the open state, and gas is still supplied to the gas stove 20. And the processor 10 knows from the control script that cooking should still continue at this time, and the fire 40 should not be extinguished. Therefore, the processor 10 will control the electronic igniter 22 to re-ignite and generate a spark, so that the fire 40 of the gas stove 20 continues to burn, enabling cooking to continue. On the contrary, when the control circuit 10 determines that the gas stove 20 has actually generated the fire 40 according to the fire detection signal, or when the control circuit 10 determines that the gas stove 20 does not generate the fire 40 but the control circuit 10 desires to control the gas stove 20 to stop the fire, the control circuit 10 controls the electronic igniter 22 not to ignite.

[0058] The present utility model does not limit the form of the fire detector 23. In this embodiment, the fire detector 23 has a third electrode E3, and the third electrode E3 is disposed above the furnace base pipeline 21 in the gas stove 20 together with the first electrode E1 and the second electrode E2 of the electronic igniter 22. Preferably, the control circuit 10 is provided with a control chip, which is used to electrically connect the third electrode E3 of the fire detector 23 with the first electrode E1 and the second electrode E2 of the electronic igniter 22. One of the first electrode E1 and the second electrode E2 is grounded, and the other is used as a high-voltage ignition rod, while the third electrode E3 directly inputs the fire detection signal into the control chip. When the control chip determines that the fire 40 is burning according to the fire detection signal, the control chip outputs a combustion state signal. When the control chip determines that the fire 40 should burn but does not burn according to the fire detection signal, the control chip outputs an abnormal warning signal.

[0059] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, can make some changes or modifications to the above-disclosed technical content to form equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
