Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and in particular relates to a gas stove control method, a device, a storage medium and a gas stove. Background Art

[0002] Gas stoves refer to kitchen appliances that use liquefied petroleum gas (liquid), artificial gas, natural gas and other gas fuels for direct fire heating. Gas stoves are also called gas stoves, stove plates, stoves, and stoves. Everyone knows how popular they are. When a gas stove is working, gas enters the stove from the air inlet pipe, enters the burner after being adjusted by the gas valve, and is mixed with a portion of air. These mixed gases are ejected from the fire holes of the ignition distributor and ignited by the ignition device to form flames. These flames are used to heat the cooker placed on the pot support.

[0003] With the advancement of science and technology, many gas stoves with additional functions have appeared on the market, such as the Chinese patent with application number 202111520975.3, which discloses a pot-moving low-fire burner, including a burner group for generating an inner ring flame and an outer ring flame; a valve body, which is connected to the burner group through a gas pipe assembly and is used to supply gas to the burner group; it also includes an infrared emitting device, which generates a signal through the infrared emitting device to control the switch of the control valve on the gas pipe assembly to switch the gas supply mode of the burner group. When the pot is close to the burner, the inner ring flame and the outer ring flame can act on the pot together to improve the combustion efficiency of the burner, and when the pot is far away from the burner, only the inner ring flame can be kept burning and the outer ring flame can be extinguished.

[0004] The shortcomings of this solution are:

[0005] (1) This solution will add infrared transmitting and receiving devices to the gas stove, which will increase the cost and also require additional heat insulation and fireproof structures to prevent the infrared transmitting and receiving devices from being damaged by high temperatures.

[0006] (2) This solution controls small fires only by reducing the gas supply through a control valve, which can easily cause the fire to be larger or smaller, and the control is not precise.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] The main purpose of the present invention is to solve the above technical problems and to provide a gas stove control method, device, storage medium and gas stove.

[0009] To achieve the above object, the technical solution of the present invention is:

[0010] The first technical solution of the present invention is a gas stove control method, which specifically includes:

[0011] Determine the current state of the cooker;

[0012] Check whether the pot has been removed from the gas stove. If so, proceed to the next step;

[0013] Detect whether the gas valve is kept open, and if so, control the gas stove to enter energy-saving mode;

[0014] The energy-saving mode is that the computer board controls the gas valve opening to be adjusted to a first opening to maintain a preset first firepower.

[0015] Furthermore, the gas stove is provided with a first temperature sensor for detecting the temperature of the cookware, and a second temperature sensor for detecting the temperature of the cookware and / or the burner is provided above the gas stove. When the first temperature received by the computer board is in a downward trend and the second temperature is in an upward trend, it is determined that the cookware is removed from the gas stove.

[0016] Furthermore, in the energy-saving mode, the computer board continuously receives the first temperature detected by the first temperature sensor, and controls the opening of the gas valve according to the first temperature.

[0017] Furthermore, if the first temperature is greater than a preset value, the computer board controls the gas valve to reduce its opening; if the first temperature is less than the preset value, the computer board controls the gas valve to increase its opening.

[0018] Furthermore, the gas stove is provided with a flame detector, and the flame detector is connected to the computer board of the gas stove. If it is detected that the flame of the gas stove has been extinguished, the computer board controls the gas valve to close.

[0019] Furthermore, when the time for the gas stove to enter the energy-saving mode once reaches a preset time, the computer board controls the gas valve to close.

[0020] The second technical solution of the present invention is a gas stove control device, comprising one or more processors and a computer-readable storage medium storing an executable program. When the one or more processors execute the executable program, the one or more processors are used to implement the gas stove control method as described above.

When the pot is temporarily removed from the fire, the user does not need to free up his hands to operate the gas stove, nor does he need to repeatedly turn the fire on and off. The operation is simple and can effectively reduce the waste of gas.

[0028] 2. In the gas stove control method of the present invention, the gas stove will automatically adjust the gas valve opening to maintain the first firepower in the energy-saving mode to prevent the firepower from being unstable or even extinguished due to gas pressure fluctuations or air fluctuations, which is safe and reliable.

Obviously, the drawings described below are only some embodiments. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. In the accompanying drawings:

[0030] Figure 1 It is a flow chart of the present invention.

[0031] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] [Example 1]

[0034] This embodiment provides a gas stove control method, which specifically includes:

[0035] Check whether the pot has been removed from the gas stove. If so, proceed to the next step;

[0036] Detect whether the gas valve is kept open, and if so, control the gas stove to enter energy-saving mode;

[0037] The energy-saving mode is that the computer board controls the gas valve opening to be adjusted to a first opening to maintain a preset first firepower.

[0038] The first firepower is preferably the minimum firepower that the gas stove can stably control.

[0039] There are many ways to determine whether the pot has been removed from the gas stove, such as using visual recognition technology, setting a visual recognition module above the gas stove for recognition; or setting a gravity sensing module on the gas stove to sense the weight of the pot; or setting an infrared transmitting and receiving module to determine whether the pot is on the gas stove by reflecting infrared rays from the pot, etc. However, the above solutions are costly and require additional new components, occupying the already crowded equipment space, which is not conducive to the overall design.

[0040] In this embodiment, the following scheme is used to determine the current state of the cookware and whether the cookware has been removed from the gas stove:

[0041] The gas stove is provided with a first temperature sensor for detecting the temperature of the pot, and a second temperature sensor for detecting the temperature of the pot and / or the burner is provided above the gas stove. Preferably, the first temperature sensor is a contact temperature sensor, and the second temperature sensor is a non-contact temperature sensor; more preferably, the first temperature sensor is a thermocouple, and the second temperature sensor is an infrared temperature sensor.

[0042] This embodiment analyzes the current state of the cookware according to the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor. It should be noted that for a household gas stove, the flame temperature of the gas can reach more than 1000°C during normal combustion, and the temperature of the pot body and the pot is generally around 100-250°C during normal cooking. When the cookware is in different states, the first temperature detected by the first temperature sensor and the second temperature detected by the second sensor are different.

[0043] The first temperature sensor uses a thermocouple. When the thermocouple is in contact with the pot body, the first temperature is the current temperature of the pot body. When the pot body leaves the thermocouple, the first temperature will reflect the current temperature of the thermocouple itself. The second temperature sensor uses an infrared temperature sensor. When the pot body is located in the gas stove, the second temperature is the temperature of the pot body or the food in the pot. When the pot body is removed from the gas stove, the infrared temperature sensor directly measures the temperature of the flame. Since the flame has no entity and there are measurement errors, the first temperature will be slightly lower than the actual temperature of the flame, but much higher than the temperature of the pot body and the pot of 100-250°C in the normal cooking state.

[0044] Furthermore, when the first temperature received by the computer board is in a downward trend and the second temperature is in an upward trend, it is determined that the pot is removed from the gas stove.

[0045] The thermocouple is located in the inner flame of the flame. On the one hand, the temperature of the inner flame is lower than that of the outer flame. On the other hand, the heating area of ​​the pot is large, and most of its position is heated by the outer flame with a higher temperature. Therefore, the temperature of the thermocouple itself is lower than that of the pot body. Therefore, when the first temperature detected by the first temperature sensor is in a downward trend, it drops from the temperature of the pot body to the temperature of the thermocouple itself, indicating that the pot is separated from the first temperature sensor; and if the second temperature is in an upward trend, it rises from the temperature in the pot to near the flame temperature, indicating that the second temperature sensor is currently directly measuring the flame temperature, indicating that the pot is removed from the gas stove. It should be noted that the temperature described above and below in this specification is in a downward trend or an upward trend, including but not limited to the temperature continuously dropping or rising at a certain speed, and the sudden and discontinuous change of temperature such as sudden rise and drop. Based on the actual operation of the user, the separation of the pot from the gas stove may be removed within a period of time, or it may be a quick and instantaneous separation. The first temperature may drop continuously or drop suddenly, and the second temperature may rise continuously or rise suddenly at the same time.

[0046] Preferably, when it is detected that the first temperature is in a downward trend and the second temperature is in an upward trend, the energy-saving mode is entered after a first preset time. Because the user may only perform a short operation of removing the pot from the fire, frequent adjustments of the gas stove and the range hood are not conducive to cooking and will also accelerate the wear of the gas stove and the range hood. The first preset time is preferably 5-15 seconds.

[0047] In some embodiments, in the energy-saving mode, the computer board continuously receives the first temperature detected by the first temperature sensor and controls the opening of the gas valve according to the first temperature. In the energy-saving mode, the first temperature sensor is always located in the flame, so even though it is not in contact with any object, the first temperature sensor itself can still detect the first temperature, and the first temperature at this time is the temperature reached by the first temperature sensor itself under the first fire. According to laboratory measurements, the preset value or preset range of the first temperature that should be reached in the energy-saving mode under normal conditions can be obtained. Depending on the material of the first temperature sensor, the preset value or preset range is also different.

[0048] In some embodiments, if the first temperature is greater than a preset value or the upper limit of a preset range, the computer board controls the gas valve to reduce the opening and slightly reduce the firepower; if the first temperature is less than a preset value or the lower limit of a preset range, the computer board controls the gas valve to increase the opening and slightly increase the firepower; if the first temperature is equal to the preset value or is within the preset range, the computer board controls the gas valve to maintain the current opening and maintain the current firepower.

[0049] When the user puts the pot back on the gas stove, the computer board controls the gas valve to return to its previous opening to ensure that the gas valve opening matches the rotation angle of the rotary switch on the gas stove. If the fire needs to be adjusted, the user can do it himself. When the user puts the pot back on the gas stove, the second temperature will show a downward trend, and it is determined that the pot has been moved back to the gas stove.

[0050] In some embodiments, the gas stove is provided with a flame detector, which is connected to the computer board of the gas stove. If the flame of the gas stove is detected to be extinguished, the computer board controls the gas valve to close. Inevitably, the gas stove may be accidentally extinguished due to various reasons such as low gas supply pressure, ambient air flow, overflow of the pot, etc., so this setting can make the kitchen environment safer.

[0051] In some embodiments, the time when the gas stove enters the energy-saving mode is also counted, because the user sometimes forgets to turn off the fire, and leaving the gas stove on for a long time not only wastes resources but also poses a huge safety hazard. Therefore, when the time when the gas stove enters the energy-saving mode once reaches a first preset time, the computer board controls the gas valve to close. The next time the user turns on the gas stove, he needs to reset the rotary switch and rotate it again to ignite.

[0052] In some embodiments, while the gas stove is adjusted accordingly, the range hood is also automatically adjusted to achieve linkage of kitchen equipment, further freeing the user's hands and improving the user experience.

[0053] For example, in a kitchen equipped with a range hood, the second temperature sensor may be disposed on the range hood, and the second temperature sensor may remotely communicate with a computer board of the gas stove through a computer board of the range hood.

[0054] In some embodiments, if the first temperature is on a downward trend and the second temperature remains stable, it means that the pot is separated from the gas stove but has not been moved out of the range of the gas stove. This situation indicates that the user is flipping the pot at this time, and this process requires firepower and will produce a lot of oil smoke. Therefore, in this case, the gas stove is not adjusted, and the power of the range hood is increased to ensure the cooking process while preventing oil smoke from overflowing.

[0055] In some embodiments, if the first temperature remains stable and the second temperature is on an upward trend, it means that the cookware is still in contact with the gas stove, and the temperature inside the pot is on an upward trend, especially when the temperature rises instantly. This situation indicates that there is a high possibility of fire in the pot. To ensure safety, the gas stove computer board controls the gas valve to close. At the same time, to prevent the range hood from sucking in the flame and causing an internal fire, the range hood is also turned off simultaneously.

[0056] Furthermore, in Chinese cooking, some dishes are deliberately set on fire in order to achieve a special flavor. Therefore, in some embodiments, a second preset time is set. If the first temperature remains stable, the second temperature rises suddenly, and the second temperature remains high for a period of time that reaches the second preset time, the gas stove computer board controls the gas valve to close, and the range hood is also closed synchronously to prevent the range hood from sucking in the flame and causing internal fire. Preferably, the second preset time is 1-10 seconds.

[0059] Furthermore,
