Description

Technical Field

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

[0002] A gas stove is a kitchen appliance that uses direct flames to heat the stove using a gaseous fuel, such as liquefied petroleum gas (liquid), manufactured gas, or natural gas. Also known as a gas stove, hob, cooktop, or cooker, gas stoves are incredibly popular. When a gas stove is operating, gas enters the stove through the inlet pipe, passes through the gas valve, and enters the burner. It mixes with air and is then ejected from the flame holes in the distributor, where it is ignited by the ignition device to form a flame. This flame is then used to heat the cookware placed on the pot holder.

[0003] Chinese cooking emphasizes the control of heat, which easily produces a large amount of oil smoke, which contains a large number of carcinogens and has a serious impact on human health. Therefore, range hoods have gradually become an indispensable kitchen appliance in every household.

[0004] With the advancement of science and technology, the interconnection of everything has become a new technological development trend. Numerous methods and devices for combined control of gas stoves and range hoods have emerged on the market. For example, Chinese patent number CN201410576395.X discloses a coordinated control system for a gas stove and range hood. This system utilizes a programmable infrared detection module, coupled with a single-chip microcomputer-programmed temperature control module, to detect, process, and generate alarms in real time regarding the temperature in the cookware. This effectively prevents accidents such as oil spontaneous combustion and dry pot burnout caused by negligence. This system transmits and processes the operating status of the gas stove via a wireless control module, which then controls the operation of the gas stove and range hood via a linkage control module. This system enables automatic control of water boiling, cooking, and steaming modes, such as automatically shutting off the gas stove and delaying the range hood shutoff after the water boils. On the one hand, this control method does not involve adjusting the gas stove; on the other hand, adjusting the range hood is too monotonous, consisting solely of selecting function levels.

[0005] In view of this, the present invention is proposed. Summary of the Invention

Obviously, the drawings described below are only some embodiments. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without inventive effort. 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 rather 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 solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to 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 linkage control method for a gas stove and a range hood, wherein a first temperature sensor for detecting the temperature of a pot is provided on the gas stove, and a second temperature sensor for detecting the temperature of the pot and / or the burner is provided on the range hood. 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.

[0035] The linkage control method of the gas stove and range hood is as follows:

[0036] Acquire a first temperature detected by a first temperature sensor and a second temperature detected by a second temperature sensor;

[0037] The operating states of the gas stove and the range hood are controlled in a preset manner according to the first temperature and the second temperature.

[0038] When the user is cooking, the first temperature sensor directly measures the first temperature of the bottom of the pot by contact, and the second temperature sensor remotely measures the second temperature inside the pot. Generally, the first temperature and the second temperature are close. Due to different measurement methods and positions, there is often a certain difference between the two. Therefore, it is a more accurate method to control the gas stove and range hood by combining the first temperature and the second temperature.

[0039] This embodiment analyzes the current state of the cookware based on the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor, thereby controlling the operating states of the gas stove and range hood. It should be noted that for a household gas stove, the flame temperature of the gas during normal combustion can reach over 1000°C, while the temperature of the pot body and the interior of the pot during normal cooking is generally around 100-250°C. Therefore, the first temperature detected by the first temperature sensor and the second temperature detected by the second sensor will differ depending on the cookware's state.

[0040] 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. Due to the lack of a physical flame and 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 in the normal cooking state of 100-250°C.

[0041] The thermocouple is located within the inner flame of the flame. On the one hand, the inner flame is cooler than the outer flame. On the other hand, the pot has a larger heating surface area, and most of its area is heated by the higher-temperature outer flame. Therefore, the thermocouple itself is at a lower temperature than the pot body. Therefore, when the first temperature detected by the first temperature sensor is on a downward trend, dropping from the pot body temperature to the thermocouple's own temperature, it indicates that the pot has separated from the first temperature sensor. On the other hand, if the second temperature is on an upward trend, rising from the pot's inner temperature to near the flame temperature, it indicates that the second temperature sensor is currently directly measuring the flame temperature, indicating that the pot has been removed from the gas stove. It should be noted that the temperature trends described above and below in this specification include, but are not limited to, a continuous decrease or increase in temperature at a certain rate, as well as sudden, discontinuous changes in temperature, such as a sudden rise or fall. Depending on the user's actual operation, the pot may be separated from the gas stove over a period of time or quickly and instantaneously. The first temperature may experience a continuous decrease or a sudden drop, while the second temperature may simultaneously experience a continuous increase or a sudden rise.

[0042] In some embodiments, the preset method includes: 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 maintains the current state without adjustment, and the power of the range hood is increased to ensure the cooking process while preventing oil smoke from overflowing.

[0043] In some embodiments, if the first temperature is on a downward trend and the second temperature is on an upward trend, it means that the pot is separated from the gas stove and has been moved out of the range of the gas stove, resulting in the second temperature sensor actually measuring the temperature of the flame. This situation indicates that the user is plating dishes or performing other operations at this time. At this time, the user has not chosen to turn off the gas stove, indicating that it will continue to use it later and no smoke will be generated. In order to save gas and electricity, the gas stove is controlled to reduce the firepower and the range hood is controlled to reduce the power. Preferably, the gas stove firepower and range hood power are controlled to the lowest level to maintain minimum gas and electricity consumption. When the user puts the pot back on the gas stove, the second temperature will be on an upward trend, and it is determined that the pot has been moved back to the gas stove. The gas stove firepower and range hood power are automatically restored to the original set values. 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 range hood are not conducive to cooking and will also accelerate the wear of the gas stove and range hood. The first preset time is preferably 5-15 seconds.

[0044] In some embodiments, in energy-saving mode, a first temperature detected by a first temperature sensor is continuously received, and the size of the gas stove flame is adjusted based on the first temperature. In energy-saving mode, the first temperature sensor is always located within the flame. Therefore, even though it is not in contact with any object, the first temperature sensor can still detect the first temperature. The first temperature in this case is the temperature reached by the first temperature sensor itself at the first power level. Laboratory measurements can provide a preset value or preset range for the first temperature that should be reached in energy-saving mode under normal conditions. The preset value or preset range varies depending on the material of the first temperature sensor.

[0045] In some embodiments, if the first temperature is greater than a preset value or the upper limit of a preset range, the gas valve is controlled to reduce its 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 gas valve is controlled to increase its opening and slightly increase the firepower; if the first temperature is equal to the preset value or within the preset range, the gas valve is controlled to maintain its current opening and maintain the current firepower.

[0046] In some embodiments, the gas stove is equipped with a flame detector. If the flame is detected to be extinguished, the gas valve is controlled to close. Inevitably, the gas stove may accidentally go out due to various reasons such as low gas supply pressure, ambient air flow, overflowing pot, etc., so this configuration can make the kitchen environment safer.

[0047] In some embodiments, the time the gas stove enters energy-saving mode is also counted. Because users sometimes forget to turn off the gas stove, leaving it on for extended periods of time wastes resources and poses significant safety risks. Therefore, when the gas stove enters energy-saving mode for a single time, the computer board controls the gas valve to close. Preferably, the second preset time is 10-60 seconds. The next time the user turns on the gas stove, they need to reset the rotary switch and rotate it again to ignite.

[0048] In some embodiments, if the first temperature remains stable and the second temperature is on an upward trend, it means that the pot is still in contact with the gas stove, and the temperature inside the pot is on an upward trend, especially if the temperature rises instantly. This situation indicates that there is a high possibility of fire in the pot. To ensure safety, the gas stove is controlled to be turned off at this time. At the same time, in order to prevent the range hood from inhaling the flame and causing an internal fire, the range hood is also turned off simultaneously.

[0049] Furthermore, because some Chinese dishes intentionally ignite a fire in the pot to achieve a unique flavor, in some embodiments, a third preset time is set. If the first temperature remains stable, the second temperature is on an upward trend, and the second temperature remains high for a period of time exceeding the third preset time, the gas stove is controlled to shut down. Simultaneously, to prevent the range hood from drawing in the flames and causing a fire, the range hood is also turned off. Preferably, the third preset time is 1-10 seconds.
