Description

Technical Field

[0001] The present invention relates to the technical field of stove control, and in particular to a stove and a dry-burning prevention control device and a control method thereof. Background Art

[0002] An anti-dry-burn gas stove is a gas stove that automatically detects the temperature of the bottom of the pot and automatically cuts off the gas supply when the temperature is too high. It can prevent dry-burning caused by forgetting to turn off the fire during cooking or water evaporation, and avoid safety accidents such as fire.

[0003] In the prior art, a dry-burn prevention gas stove usually adds a temperature-sensing column in the middle of the burner, which senses the temperature of the pot bottom through the temperature-sensing column. When the temperature of the pot bottom is too high, the gas supply to the burner is automatically cut off. The existing temperature measurement protection strategy has the following problems: the types of pots used by users during cooking are different, such as non-metallic pots, aluminum pots, flat pans or round-bottomed pots. For non-metallic pots, during the timing operation, the temperature of the pot bottom detected by the temperature-sensing column is too high, which can easily cause the stove high-temperature protection to shut down in the middle, affecting the user experience; for pots such as aluminum pots whose bottoms are prone to concave deformation, it is easy for the top of the temperature-sensing column to not be in place, causing the dry-burn prevention to be falsely triggered; in scenes such as frying and flipping the pot, it is easy for the temperature-sensing column to collide with the bottom of the pot and be damaged.

This embodiment can be applied to a gas stove equipped with an anti-dry-burning function. Figure 2 is a structural schematic diagram of a stove with an anti-dry-burning control device provided by an embodiment of the present invention, Figure 3 It is an exploded view of a stove with an anti-dry-burning control device provided in an embodiment of the present invention.

[0035] See also Figure 2 and Figure 3As shown, the stove of the present application includes a pot rack 1, a water receiving tray 2, a burner 3, an anti-dry burning module 11, a burner head 4, a stove chassis 5 and a stove panel 13. Among them, the pot rack 1 is used to support the pot to be tested, and the bottom surface of the pot abuts against the upper surface of the pot rack 1. The pot rack 1 is placed above the water receiving tray 2, and the water receiving tray 2 is used to support the limited pot rack. The upper part of the burner head 4, the lower part of the water receiving tray 2 and the stove panel 13 are fixedly connected by fasteners; the lower part of the burner head 4 is fixedly connected to the stove chassis 5 by fasteners. The anti-dry burning module 11 includes: an anti-dry burning probe 111, which is arranged in the hollow part of the burner head of the burner 3. The anti-dry burning probe 111 can use a temperature sensor and / or a thermistor to detect the bottom temperature of the pot of the pot to be tested. In this embodiment, classified by material, the cookware to be tested includes but is not limited to any of the following: non-metallic pots and metal pots, wherein non-metallic pots include but are not limited to: casserole pots, stone pots, ceramic pots or glass pots; metal pots include but are not limited to: aluminum pots, iron pots or stainless steel pots; classified by shape, the cookware to be tested includes but is not limited to: flat pans or round bottom pots; classified by function, the cookware to be tested includes but is not limited to: woks, steaming pots or stew pots.

[0036] See also Figure 1 As shown, the control device of the present application includes: a detection module 100 , a driving component 200 and a control module 300 .

[0037] Among them, the detection module 100 is used to obtain static detection data and dynamic detection data of the pot to be tested. In this embodiment, the static detection data is the data fed back after the static characteristics of the pot to be tested, such as shape, material or type, are detected. The dynamic detection data is the data fed back after the action state detection is performed on the pot to be tested. In this embodiment, different types of sensors or other detection elements can be set at the position facing the bottom surface of the pot to be tested, for collecting detection data at the corresponding position. Typically, the detection module 100 includes but is not limited to at least one of the following: an image sensor, an ultrasonic sensor, a displacement sensor, a strain force detection sensor, an acceleration sensor, a capacitive sensor, a resistance sensor or a magnetoelectric sensor.

[0038] The driving component 200 is used to drive the anti-dry-burning module 11 to move. In the present embodiment, the driving component 200 is connected to the anti-dry-burning module 11 in a transmission manner to drive the anti-dry-burning module 11 to move in a direction toward or away from the bottom surface of the pot to be tested. Exemplarily, when the driving component 200 drives the anti-dry-burning module 11 to move in a direction toward the bottom surface of the pot to be tested, if the anti-dry-burning probe 111 of the anti-dry-burning module 11 abuts against the bottom surface of the pot, the driving component 200 stops driving; when the driving component 200 drives the anti-dry-burning module 11 to move in a direction away from the bottom surface of the pot to be tested, the driving component 200 can increase the distance between the anti-dry-burning probe 111 and the bottom surface of the pot according to the calibration data, or directly drive the anti-dry-burning probe 111 to hide inside the burner.

[0039] The control module 300 is connected to the detection module 100, the drive component 200 and the anti-dry-burning module 11 respectively, and is used to send a drive control signal to the drive component 200 according to the static detection data and the dynamic detection data, so that the drive component 200 drives the anti-dry-burning module 11 to move in the direction toward or away from the pot to be tested, and / or adjusts the working state and the protection temperature threshold of the anti-dry-burning module 11 according to the static detection data and the dynamic detection data. Among them, the working state includes but is not limited to: turning off the anti-dry-burning module 11, and maintaining the anti-dry-burning module 11 to perform temperature measurement on the bottom of the pot to be tested. The protection temperature threshold is the temperature that triggers the anti-dry-burning protection action (such as shutdown) set based on the temperature measurement data of the anti-dry-burning module 11.

[0040] In this embodiment, a drive control signal is sent to the drive component 200 based on the static detection data and the dynamic detection data, so that the drive component 200 drives the anti-dry-burning module 11 to move in a direction toward or away from the cookware to be tested, including: identifying the cooking scene based on the static detection data and the dynamic detection data, and determining the drive control signal based on the cooking scene.

[0041] Specifically, during the cooking process, the detection module 100 feeds back static detection data and dynamic detection data to identify the material, shape or type of the cookware, and identifies the cooking scene based on at least one of the material, shape or type of the cookware and the dynamic detection data. If the current cooking scene is a cooking scene with easily deformable pots (for example, an aluminum pot), the control driving component 200 drives the anti-dry-burning probe 111 to rise and abut against the bottom of the pot; if the type of the pot to be tested is a cooking scene with non-easily deformable pots (for example, a casserole pot), the pot movement is identified based on an ultrasonic sensor, a displacement sensor, a strain force detection sensor or an acceleration sensor. When the type of the pot to be tested is a cooking scene with non-easily deformable pots and the pot to be tested has no continuous movement, it is determined that the current cooking scene is casserole cooking, and the control driving component 200 drives the anti-dry-burning probe 111 to abut against the bottom of the pot, and increases the protection temperature threshold of the anti-dry-burning module 11; when the type of the pot to be tested is a cooking scene with non-easily deformable pots and the pot to be tested has continuous movement, it is determined that the current cooking scene is cooking with an inverted pot, and the control driving component 200 drives the anti-dry-burning probe 111 to descend to the inside of the burner 3. By automatically identifying the static and dynamic detection data of the cookware, and adjusting the position, working status and protection temperature threshold of the anti-dry-burning module based on different detection data, the problem that the existing anti-dry-burning module is difficult to be compatible with different cookware, which leads to false triggering of the anti-dry-burning protection or collision damage of the temperature measuring element, is solved. The temperature measurement protection accuracy of the anti-dry-burning module is improved, misjudgment is reduced, the applicability of the anti-dry-burning module to different cookware is enhanced, the anti-dry-burning effect is improved, false triggering or collision damage of the anti-dry-burning module is avoided, the user experience is improved, and the service life is extended.

[0042] Optionally, the control module 300 of the present invention is configured to adjust the working state and protection temperature threshold of the anti-dry-burning module according to at least one of the material, shape or type of the cookware and the dynamic detection data, specifically including the following control strategies:

[0043] In some embodiments, the control module 300 is configured to: identify the cooking scene according to the material detection data, the shape detection data and the dynamic detection data, and adjust the working state and the protection temperature threshold of the anti-dry burning module according to the cooking scene. Specifically, when the cooker is working, the control module 300 can determine the material of the cooker according to the material monitoring data of the cooker. Since the temperature of the bottom of the cooker of different materials is different during the cooking process, the control module 300 will adjust the anti-dry burning protection temperature threshold according to the material of the cooker. For example, if it is detected that the material of the cooker to be tested is a non-metallic material, since the non-metallic cooker has poor thermal conductivity, the bottom temperature of the non-metallic cooker will be higher during the cooking process, so it is necessary to increase the anti-dry burning protection temperature threshold; while the metal cooker has good thermal conductivity, and the difference between the bottom temperature of the metal cooker and the temperature of the food in the cooker during the cooking process is small. If it is detected that the material of the cooker to be tested is a metal material, it is necessary to lower the anti-dry burning protection temperature threshold, so as to avoid the occurrence of misjudgment of the anti-dry burning module 11. At the same time, the control module 300 determines the shape of the pot and whether the pot is moving according to the shape monitoring data and the dynamic detection number. If the pot is moving, it is determined that the user is moving the pot, such as the user is shaking the pot or transferring the pot, and the anti-dry-burning module 11 is turned off to prevent the pot from colliding with the anti-dry-burning module 11 and damaging the pot or the anti-dry-burning module 11. If the control module 300 determines that the pot is stationary, the anti-dry-burning module 11 will be turned on and abut the bottom of the pot to detect the temperature of the bottom of the pot to prevent dry burning.

[0044] In other embodiments, the control module 300 is configured to: identify the cooking scene according to the material detection data and the dynamic detection data, and adjust the working state and the protection temperature threshold of the anti-dry burning module according to the cooking scene. Specifically, when the cooker is working, the control module 300 can determine the material of the cooker according to the material monitoring data of the cooker. Since the temperature of the bottom of the cooker of different materials is different during the cooking process, the control module 300 will adjust the anti-dry burning protection temperature threshold according to the material of the cooker. For example, if it is detected that the material of the cooker to be tested is a non-metallic material, the bottom temperature of the non-metallic cooker will be higher during the cooking process due to the poor thermal conductivity of the non-metallic cooker. Therefore, it is necessary to increase the anti-dry burning protection temperature threshold; while the thermal conductivity of the metal cooker is good, and the difference between the bottom temperature of the metal cooker and the temperature of the food in the cooker during the cooking process is small. If it is detected that the material of the cooker to be tested is a metal material, it is necessary to lower the anti-dry burning protection temperature threshold, so as to avoid the occurrence of misjudgment of the anti-dry burning module 11. At the same time, the control module 300 determines whether the cooker is moving according to the dynamic detection data. If the cookware is moving, it is determined that the user is moving the cookware, for example, the user is shaking the cookware or transferring the cookware, and the anti-dry-burning module 11 is turned off to prevent the cookware from colliding with the anti-dry-burning module 11 and damaging the cookware or the anti-dry-burning module 11. If the control module 300 determines that the cookware is stationary, the anti-dry-burning module 11 is turned on and abuts against the bottom of the cookware to detect the temperature of the bottom of the cookware to prevent dry-burning.

[0045] In some other embodiments, the control module 300 is configured to: identify the cooking scene according to the type detection data and the dynamic detection data, and adjust the working state and protection temperature threshold of the anti-dry burning module according to the cooking scene. Specifically, when the cooker is working, the control module 300 can identify the material and shape of the cooker according to the type monitoring data of the cooker. Since the temperature of the bottom of the cooker of different materials is different during the cooking process, the control module 300 will adjust the anti-dry burning protection temperature threshold according to the material of the cooker. For example, if it is detected that the material of the cooker to be tested is a non-metallic material, the bottom temperature of the non-metallic cooker will be higher during the cooking process due to the poor thermal conductivity of the non-metallic cooker, so it is necessary to increase the anti-dry burning protection temperature threshold; while the metal cooker has good thermal conductivity, and the difference between the bottom temperature of the metal cooker and the temperature of the food in the cooker during the cooking process is small. If it is detected that the material of the cooker to be tested is a metal material, it is necessary to lower the anti-dry burning protection temperature threshold, so as to avoid the occurrence of misjudgment of the anti-dry burning module 11. At the same time, the control module 300 determines the shape of the pot and whether the pot is moving according to the type monitoring data and the dynamic detection number. If the pot is moving, it is determined that the user is moving the pot, such as the user is shaking the pot or transferring the pot, and the anti-dry-burning module 11 is turned off to prevent the pot from colliding with the anti-dry-burning module 11 and damaging the pot or the anti-dry-burning module 11. If the control module 300 determines that the pot is stationary, the anti-dry-burning module 11 will be turned on and abut the bottom of the pot to detect the temperature of the bottom of the pot to prevent dry burning.

[0046] Optionally, the control module 300 of the present invention is further configured to: identify the deformable pot cooking scene, the non-deformable pot cooking scene or the inverted pot cooking according to at least one of the pot material, the pot shape or the pot type, and the dynamic detection data, and match the deformable pot cooking scene, the non-deformable pot cooking scene and the inverted pot cooking with corresponding drive control signals, specifically including the following control strategies:

[0047] In some embodiments, the control module 300 is configured to: determine whether the cookware to be tested is a deformable cookware based on the material or type of the cookware, and when the cookware to be tested is a deformable cookware, control the drive component 200 to drive the anti-dry-burning module 11 to move in a direction toward the cookware to be tested until the anti-dry-burning module 11 abuts against the bottom of the cookware to be tested; and / or, when the type of the cookware is a non-deformable cookware and continuous movement of the cookware is identified based on dynamic detection data, drive the anti-dry-burning module 11 to move in a direction away from the cookware to be tested.

[0048] Optionally, the detection module 100 includes: a motion detection unit for collecting dynamic detection data of the cookware to be tested; the detection module 100 also includes at least one of the following: a material detection unit, a shape detection unit, and a type detection unit. Among them, the material detection unit is used to obtain material detection data of the cookware to be tested; the shape detection unit is used to obtain shape detection data of the cookware to be tested; and the cookware type detection unit is used to obtain type detection data of the cookware to be tested.

[0049] Optionally, the shape detection unit includes but is not limited to: an ultrasonic sensor or an image sensor. The number of ultrasonic sensors is greater than or equal to 2. Preferably, 3 or four ultrasonic sensors are provided. Multiple ultrasonic sensors are evenly arranged on the surface of the water receiving tray facing the side of the pot to be tested, and the projection of the ultrasonic sensor on the kitchen panel falls within the circumferential range of the inner circle of the pot rack. The control module is configured to determine the shape of the pot according to the shape detection data. Specifically, during the cooking process, the ultrasonic sensor emits ultrasonic waves to identify the real-time distance from the bottom surface of the pot supported by the pot rack, and identifies the shape of the pot to be tested according to the distance and changes in the distance at various places in the space.

[0050] Optionally, the material detection unit includes at least one of the following: an electrical detection unit, an optical detection unit, and a thermal conductivity detection unit.

[0051] Among them, the electrical detection unit is used to detect the conductive properties of the pot to be tested. Typically, the electrical detection unit includes but is not limited to: a capacitive sensor, a resistance sensor or a magnetoelectric sensor. Exemplarily, taking a capacitive sensor as an example, the capacitive sensor is arranged at the probe head of the anti-dry burning module 11, and the capacitive sensor and the bottom surface of the pot to be tested can form a capacitor plate, and the capacitance calculation formula is C=εS / (4πkd), wherein ε represents the dielectric constant (for a parallel plate capacitor, ε is the dielectric constant of the medium between the plates), S represents the area facing the capacitor plate, d represents the distance from the capacitor plate (i.e., the bottom surface of the pot), and k represents the electrostatic force constant. The control module of the present application is also configured to: determine the resistance and capacitance values ​​of the pot to be tested according to the material detection data collected by the electrical detection unit, and determine the material of the pot according to the resistance and capacitance values. Specifically, the presence or absence of capacitance can be used to determine whether the pot is a metal material (capacitor is detected) or a non-metallic material (capacitor is not detected), and further, the specific metal material (such as aluminum alloy or iron alloy) can be determined by the size of the capacitance value obtained by detection.

[0052] The optical detection unit is used to detect the radiation coefficient of the pot to be tested to a specific light wave. Typically, the optical detection unit includes but is not limited to: a radiometer or an infrared radiation detection unit. Exemplarily, taking the infrared radiation detection unit as an example, the infrared radiation detection module is arranged in the outer peripheral direction of the pot rack 1, abutting against the water receiving tray 2 or the upper surface of the panel 13, and detecting the radiation coefficient of the bottom surface of the pot. The control module 300 is also configured to: determine the radiation coefficient of the pot to be tested according to the material detection data collected by the optical detection unit, and determine the material of the pot according to the radiation coefficient. Specifically, the optical detection module can be arranged in the outer peripheral direction of the pot rack 1, abutting against the water receiving tray 2 or the upper surface of the panel 13, and the material of the pot can be determined by receiving and analyzing the radiation coefficient of the bottom surface of the pot. For example, when the radiation coefficient of the bottom surface of the pot to be tested is less than the radiation coefficient critical value (for example, 0.6), the pot to be tested is determined to be a non-metallic pot; when the radiation coefficient of the bottom surface of the pot to be tested is greater than or equal to the radiation coefficient critical value (for example, 0.6), the pot to be tested is determined to be a metal pot.

[0053] The thermal conductivity detection unit is used to detect the temperature change of the bottom of the electric cookware. Typically, the thermal conductivity detection unit includes but is not limited to: a temperature sensor, a thermocouple sensor or a thermistor sensor. Exemplarily, taking the temperature sensor as an example, the temperature sensor is arranged in the outer peripheral direction of the pot rack 1, abutting against the upper surface of the water receiving tray 2 or the panel 13, and detecting the temperature change of the bottom of the pot. The control module 300 is also configured to: determine the thermal conductivity of the pot to be tested according to the material detection data collected by the thermal conductivity detection unit, and determine the material of the pot according to the thermal conductivity. Specifically, the thermal conductivity detection unit measures the change of the temperature at the bottom of the pot through a temperature probe, and then analyzes the change of the temperature at the bottom of the pot to determine the thermal conductivity of the pot, thereby determining the material of the pot. For example, when the thermal conductivity is less than the critical value of the thermal conductivity, the pot to be tested is determined to be a non-metallic pot; when the thermal conductivity is greater than or equal to the critical value of the thermal conductivity, the pot to be tested is determined to be a metal pot.

[0054] Optionally, the motion detection unit includes at least one of the following: an ultrasonic sensor, a displacement sensor, a strain force detection sensor, or an acceleration sensor. The motion detection unit can identify at least one of the real-time distance from the bottom surface of the pot supported by the pot rack, the pressure borne by the pot rack 1, and the acceleration of the pot, and detect the pot motion and pot shape based on at least one of the real-time distance from the bottom surface of the pot supported by the pot rack, the pressure borne by the pot rack 1, and the acceleration of the pot.

[0055] Among them, the number of ultrasonic sensors is greater than or equal to 1. When the number of ultrasonic sensors is greater than or equal to 2, multiple ultrasonic sensors are evenly arranged within the inner circumferential range of the pot rack 1 to identify the real-time distance between the bottom of the pot and the transmitting end of the ultrasonic sensor; the control module is also configured to: determine the pot action and pot shape according to the real-time distance collected by at least two ultrasonic sensors. Specifically, during the detection process, the ultrasonic sensor emits ultrasonic waves to identify the real-time distance from the bottom of the pot supported by the pot rack, and identifies the pot action and pot shape according to the distance and change of each place in the space. For example, if the real-time distance between the bottom of the pot to be tested and the ultrasonic sensor continues to change, it is determined that the pot to be tested is moving; if the real-time distance between the bottom of the pot to be tested and the ultrasonic sensor does not change for a long time (for example, within 2 seconds), it is determined that the pot is in a stationary state.

[0056] The displacement sensor is used to detect the displacement of the bottom of the pot. The displacement sensor is set at the joint between the foot piece of the pot rack 1 and the water receiving tray 2, and the number of displacement sensors is consistent with the number of foot pieces of the pot rack 1. The control module 300 is also used to determine the pot movement according to the real-time displacement collected by the displacement sensor, and determine the cooking scene according to the pot movement. Specifically, during the detection process, the displacement sensor identifies the real-time displacement of the bottom surface of the pot, and identifies the pot movement according to the real-time displacement of the bottom surface of the pot. For example, if the bottom surface of the pot to be tested continues to move back and forth, it is determined that the user is flipping the pot.

[0057] The strain force detection sensor is used to detect the pressure exerted on the pot rack 1. The pressure exerted on the strain force detection sensor by the pot rack 1 can indirectly reflect the action of the pot. The strain force detection sensor is arranged at the joint between the foot piece of the pot rack 1 and the water receiving tray 2, and the number of the strain force detection sensors is consistent with the number of the foot pieces of the pot rack 1. The control module 300 is also used to determine the action of the pot according to the pressure data collected by the strain force detection sensor, and determine the cooking scene according to the action of the pot. Specifically, during the detection process, the strain force detection sensor detects the pressure exerted on the strain force detection sensor by the pot rack 1, and identifies the action of the pot according to the change of the pressure data. For example, if the pressure exerted on the strain force detection sensor is greater than the weight of the pot rack 1, and the pressure remains unchanged for a long time, it is determined that the pot is placed on the pot rack 1 and is stationary; if the pressure exerted on the strain force detection sensor is equal to the weight of the pot rack 1, it is determined that there is no pot on the pot rack 1.

[0058] The acceleration sensor is used to detect the acceleration of the pot. The acceleration sensor is set at the place where the foot of the pot rack 1 abuts the water receiving tray 2, and the number of acceleration sensors is consistent with the number of foot of the pot rack 1. The control module 300 is also used to determine the pot action according to the acceleration of the pot, and determine the cooking scene according to the pot action. Specifically, during the detection process, the acceleration sensor detects the acceleration of the pot, and the control module 300 identifies the pot action according to the acceleration of the pot. For example, if the acceleration sensor detects that the acceleration of the pot continues to change, it is determined that the user is flipping the pot.

[0059] Optionally, the type detection unit may be a wireless radio frequency detection unit. The control module of the present invention is configured to determine the type of the cookware according to the type detection data. Specifically, the wireless radio frequency detection unit includes an identification unit and an editable identification unit; the editable identification unit is provided on the cookware to be tested, and is used to store at least one of the cookware material, cookware shape or cookware type of the cookware to be tested, and the stored data is editable data; the identification unit is communicatively connected to the control module 300, or is integrated with the control module 300. The editable identification unit includes a near-field radio frequency identification tag, which can be provided on the handle, the pot handle or the auxiliary ear of the cookware; the identification unit includes a near-field radio frequency identifier, which can identify at least one of the cookware material, the cookware shape or the cookware type according to the near-field radio frequency identification tag.
