Among them, some cooking devices, in order to achieve precise temperature control to better control the cooking temperature of food materials, detect the temperature of the cooking liquid by setting a sensor, but the temperature detection method still has the following problems: first, the cooking device cannot determine whether the temperature measurement structure of the sensor is in contact with the liquid. When the liquid added by the user, i.e., water, is too little, or when the sensor is not placed in the liquid, the sensor cannot detect the liquid because it is not in contact with the liquid, which leads to inaccurate temperature measurement or even failure of temperature measurement; second, the installation and placement structure of the sensor causes it to form a situation where it blocks the user from performing cooking operations, affecting the user from performing cooking operations such as placing food materials, taking out food materials or adding liquid, making the user's operation inconvenient, and the user is also prone to bumping into the sensor, causing the sensor to be damaged; the above problems need to be further solved to improve the reliability and accuracy of the sensor temperature measurement, and at the same time improve the convenience of the user in cooking operations.

[0022] In the control method of the aforementioned cooking device, when the cooking cover forms an open structure to the cooking cavity, the temperature measuring component is folded back on the cooking cover so that the temperature measuring component does not contact the liquid in the cooking cavity;

[0030] and / or, the cooking mode is set to a low-temperature cooking mode, in which the working state of the heating element is controlled at least by the temperature of the liquid in the cooking cavity detected by the temperature measuring component, so that the liquid in the cooking cavity is always in a non-boiling state;
[0031] And / or, the distance from the end position of the temperature measuring component to the side wall of the cooking cavity in the radial direction of the cooking cavity is set to be smaller than half of the distance from the end position of the temperature measuring component to the central axis position of the cooking cavity in the radial direction of the cooking cavity, so that the end position of the temperature measuring component is relatively far away from the food placed at the center position of the cooking cavity.
[0032] Compared with the prior art, the present invention has the following beneficial effects:
[0033] The temperature measuring component of the present solution realizes contact temperature measurement of the liquid in the cooking cavity, and the detected temperature is the actual cooking temperature of the food, thereby achieving the effect of accurate temperature measurement, which is beneficial to control the working state of the heating element based on the temperature detected by the temperature measuring component, thereby achieving the effect of accurate temperature control, so as to better improve the cooking effect of the food and improve the cooking taste.
[0034] The temperature measuring component of the present scheme can be used to detect and determine whether the temperature measuring component is in contact with the liquid in the cooking cavity under the protruding structure to realize contact temperature measurement, and to determine whether the temperature detected by the temperature measuring component is the temperature of the liquid, thereby ensuring that the temperature measuring component is a structure that performs contact temperature measurement on the liquid in the cooking mode, thereby improving the reliability of the temperature measuring component in contacting the liquid for temperature measurement, and improving the accuracy of detecting the liquid temperature, thereby preventing problems such as inaccurate temperature measurement and temperature measurement failure caused by the temperature measuring component not contacting the liquid.
[0035] This solution also improves the accuracy and reliability of the judgment by setting up a temperature sensing component, and jointly realizing the judgment of whether the temperature measuring component is in contact with liquid to measure the temperature through the temperature sensing component and the temperature measuring component. It can effectively judge whether the temperature measuring component is in contact with liquid to measure the temperature, thereby improving the accuracy and reliability of the temperature measurement by the temperature measuring component.
[0036] This solution compares the temperature value detected by the temperature measuring component with the temperature value detected by the temperature sensing component, and reliably determines whether the temperature measuring component is in contact with liquid through comparison, thereby improving the reliability and accuracy of the judgment.
[0037] This solution realizes controlling the start of the cooking mode based on a structure that determines whether the temperature measuring component is in contact with liquid to perform temperature measurement, realizes the effect that the temperature measuring component is in contact with liquid to perform temperature measurement in the cooking mode, realizes the detection of the actual cooking temperature of the cooking, and then realizes controlling the state of the cooking mode based on the detected cooking temperature, and controls the working state of the heating element, and realizes the effects of precise temperature measurement and precise temperature control in the cooking mode.
[0038] The structural setting of the temperature measuring component of the present scheme enables the temperature measuring component to switch between a raised structure and a folded structure. The temperature measuring component can contact the liquid in the cooking cavity for contact temperature measurement under the raised structure. The temperature measuring component will not form a structure that blocks the user from performing cooking operations in the folded structure, so that the user will not collide with the temperature measuring component when performing cooking operations, thereby improving the reliability and safety of the temperature measuring component and at the same time improving the convenience of the user in performing cooking operations.
[0039] In this solution, the temperature measuring component can switch between a raised structure and a folded structure, so that when the cooking cover forms an open structure with respect to the cooking cavity and the user performs cooking operations, the user is not likely to collide with the temperature measuring component, which can effectively prevent the temperature measuring component from being damaged due to collision.
[0040] In this solution, the temperature measuring component can realize contact temperature measurement of the liquid in the cooking cavity, so that the detected temperature is the actual temperature of the cooking food, the detected temperature deviation is small, the temperature is more accurate, and the accuracy of the cooking temperature of the cooking food can be effectively improved, the effect of precise temperature control can be achieved, and it is beneficial to improve the cooked taste of the food.
[0041] The structure of the temperature measuring component in the present solution allows the temperature measuring component to be moved in a directional manner to move away from the food when the food blocks the temperature measuring component, thereby effectively preventing the temperature measuring component from entering the food or the food from adhering to the temperature measuring component, so that the end position of the temperature measuring component can effectively contact the liquid for temperature measurement, thereby improving the accuracy and reliability of temperature measurement.
[0042] The end position of the temperature measuring component of the present solution can effectively avoid being inserted into food materials, and can effectively prevent food materials from adhering to the end position of the temperature measuring component, thereby enabling the end position of the temperature measuring component to be effectively kept in a clean state, which not only makes the temperature detected by the temperature measuring component more accurate, but also makes the temperature measuring component easier to maintain and clean.
[0043] The position of the temperature measuring component of the present solution makes it difficult for it to contact the food in the cooking cavity when it is in a raised structure. The end position of the temperature measuring component is relatively close to the side wall of the cooking cavity, so that the end position of the temperature measuring component can effectively form a structure in direct contact with the liquid. At the same time, the end position of the temperature measuring component is not easy to contact the food, and the end position of the temperature measuring component can be effectively kept in a clean state, which not only makes the temperature detected by the temperature measuring component more accurate, but also makes the temperature measuring component easier to maintain and clean.
[0044] In this solution, the state of the low-temperature cooking mode can be controlled by the structure in which the temperature measuring component contacts the liquid for temperature measurement, and low-temperature cooking of meat ingredients can be achieved through the low-temperature cooking mode, thereby achieving the effects of precise temperature measurement and precise temperature control, which is beneficial to improving the low-temperature cooking effect of meat ingredients and improving the taste of low-temperature cooking.

[0050] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.
[0051] Embodiment: The control method of the cooking device 1 of the present invention is as follows: Figures 1 to 4As shown in the structure, the cooker 1 is mainly used for cooking food materials. The present solution particularly relates to a cooker 1 with a low-temperature cooking function. The cooker 1 starts a cooking mode, and mainly starts the low-temperature cooking mode to perform low-temperature cooking on meat food materials. In the low-temperature cooking mode, the effects of precise temperature measurement and precise temperature control are achieved, which can effectively improve the low-temperature cooking effect on food materials.
[0052] The control method of the cooker 1 is that the cooker 1 comprises a cooking pot 20 and a cooking cover 10. The cooking pot 20 is provided with a cooking cavity 201. The cooking cavity 201 is used to hold food and liquid, and the liquid is water. The cooking cover 10 is used to open and close the cooking cavity 201. The cooking cover 10 can be provided with a rotatable installation structure. For example, the cooking cover 10 can be rotatably or swingably installed on a cooking base. The cooking base is provided with an installation cavity for installing and placing the cooking pot 20. When the cooking cover 10 is subjected to an external force to perform a rotational movement, an opening structure and a closing structure of the cooking cavity 201 can be formed. When the cooking cover 10 forms an opening structure of the cooking cavity 201, a user can perform cooking operations on the cooking cavity 201. When the cooking cover 10 forms a closing structure of the cooking cavity 201, the cooking operation can be controlled. The cooker 1 starts working to perform cooking, and also includes a temperature measuring component 40 and a heating element 30. The temperature measuring component 40 is installed on the cooking cover 10 for temperature measurement. The heating element 30 is located on the outer side of the cooking chamber 20 for heating. The heating element 30 can be set as a heating plate, an electromagnetic coil plate, etc. The temperature measuring component 40 is mainly installed on the cooking cover 10 to perform synchronous rotation with the cooking cover 10, so that the temperature measuring component 40 enters the cooking cavity 201 or separates from the cooking cavity 201, thereby realizing the temperature measurement effect of the temperature measuring component 40 on the liquid in the cooking cavity 201. The cooker 1 adjusts the working state based on the temperature of the liquid detected by the temperature measuring component 40, thereby realizing effective cooking of the ingredients based on accurate temperature measurement, improving the cooking taste of the ingredients, and improving the user experience.
[0053] The cooking device 1 of this scheme also includes the following control method:
[0054] The control method includes controlling the cooker 1 to start a cooking mode;
[0055] Before starting the cooking mode or in the cooking mode, at least including a control start pre-check mode;
[0056] In the pre-check mode, it includes controlling the temperature measuring component 40 to measure the temperature and feeding back the temperature value to compare with the preset temperature value, and judging whether the temperature measuring component 40 and the liquid in the cooking cavity 201 are in contact with each other according to the comparison result, and judging whether the temperature detected by the temperature measuring component 40 is the temperature value of the liquid in the cooking cavity 201, so as to control the state of the cooking mode.
[0057] Among them, the preset temperature value is mainly set in the controller, and the preset temperature value can be used to form a preset threshold value. The temperature measuring component 40 is used to measure the temperature and the temperature value fed back is compared with the preset temperature value, so as to determine whether the temperature measuring component 40 contacts the liquid for temperature measurement, and whether the fed back temperature value is the temperature value of the liquid, and then the state of the cooking mode is controlled based on the judgment result.
[0058] The states of the cooking modes include start, stop, continue, stop, etc.
[0059] In the present solution, in the pre-check mode, the controller also controls the heating element 30 to start working to heat the cooking pot 20. After the preset time T1, the temperature measuring component 40 detects the temperature and feeds back the temperature value W1. At this time, the temperature value fed back by the temperature measuring component 40 is compared with the preset temperature value, that is, at this time, it is determined whether the temperature value W1 is greater than or equal to the preset temperature value W0; by comparing the temperature value W1 with the preset temperature value W0, it is determined whether the liquid transfers the temperature to the temperature measuring component 40 during the heating process, and then it is determined whether the temperature measuring component 40 contacts the liquid to measure the temperature, so as to control the state of the cooking mode according to the comparison result.
[0060] Regarding the comparison result, if yes, it is determined that the cooking cover 10 forms a closing structure for the cooking cavity 201 and a portion of the temperature measuring component 40 is located in the cooking cavity 201 to be in contact with the liquid in the cooking cavity 201, and the temperature value W1 is determined to be the temperature value of the liquid in the cooking cavity 201. At this time, the controller controls to start the cooking mode or the controller controls the cooking mode to continue; in the cooking mode, the temperature measuring component 40 forms a structure for contact temperature measurement of the liquid in the cooking cavity 201.
[0061] Regarding the comparison result, if no, it is determined that the temperature measuring component 40 and the liquid in the cooking cavity 201 are not in contact with each other, and the temperature value W1 is not the temperature value of the liquid in the cooking cavity 201. At this time, the controller controls not to start the cooking mode or the controller controls the cooking mode to stop.
[0062] Specifically, with respect to the temperature value information part fed back by the temperature measuring component 40 and the comparison result part, after the preset time length T1, the temperature measuring component 40 detects the temperature and feeds back the temperature value W1, and at this time, it is judged whether the temperature value W1 is greater than or equal to the preset temperature value W0; it can be understood that after the preset time length T1, if the temperature value W1 fed back by the temperature measuring component 40 is less than the preset temperature value W0, it can be judged that the temperature measuring component 40 does not contact the liquid, resulting in the temperature generated by the liquid in the cooking cavity 201 during the heating process not being transmitted to the temperature measuring component 40. At this time, the temperature measuring component 40 is in the air state to detect the temperature of the air in the cooking cavity 201, rather than contacting the liquid to detect the temperature. Therefore, it can be judged that the temperature measuring component 40 does not constitute a structure in contact with the liquid in the cooking cavity 201, and does not form a contact temperature measurement structure. At this time, the temperature value W1 is not the temperature value of the liquid in the cooking cavity 201, but the temperature value of the air; it can also be understood that It is understood that after the preset time T1, if the temperature value W1 fed back by the temperature measuring component 40 is greater than or equal to the preset temperature value W0, it can be determined that the temperature measuring component 40 is in contact with the liquid, and the temperature generated by the liquid in the cooking cavity 201 during the heating process is transmitted to the temperature measuring component 40. At this time, the temperature measuring component 40 achieves a heating effect in the state of contacting the liquid, so that the temperature value W1 satisfies or is greater than or equal to the preset temperature value W0. Therefore, it can be determined that the temperature measuring component 40 and the liquid in the cooking cavity 201 are in contact with each other for contact temperature measurement, and the temperature value W1 is the temperature value of the liquid in the cooking cavity 201; that is, based on the temperature value W1 fed back by the temperature measuring component 40, it can be determined whether the temperature measuring component 40 is in contact with the liquid in the cooking cavity 201. When the temperature measuring component 40 is in contact with the liquid, the temperature measuring component 40 can effectively detect the temperature of the liquid, that is, the actual cooking temperature, so as to control the state of the cooking mode based on the temperature of the liquid.
[0063] Among them, when it is determined that the temperature measuring component 40 is in contact with the liquid for contact temperature measurement, the cooking mode can be controlled to start or the cooking mode can be controlled to continue. In the cooking mode, the temperature measuring component 40 performs contact temperature measurement on the liquid to achieve the effect of accurate temperature measurement and accurate temperature control.
[0064] When it is determined that the temperature measuring component 40 and the liquid are not in contact with each other, the cooking mode can be controlled not to be started or the cooking mode can be controlled to be stopped.
[0065] Optionally, the size of the preset time length T1 is affected by the heating power of the heating element 30 and the amount of water in the cooking cavity 201. In this embodiment, when the heating power of the heating element 30 is set to 1200 watts to 2000 watts, the preset time length T1 is set to be in the range of 30 seconds to 120 seconds. After the cooker 1 works for the preset time length T1, the temperature measuring component 40 detects the temperature and feeds back the temperature value W1. Similarly, the size of the preset temperature value W0 is also affected by the heating power of the heating element 30 and the amount of water in the cooking cavity 201. Under the above definition, the preset temperature value W0 is set to be in the range of 40 degrees to 60 degrees. The temperature value W1 is compared with the preset temperature value W0 to determine whether the temperature measuring component 40 is in contact with the liquid.
[0066] In the present solution, the cooker 1 further comprises a temperature sensing component 50 for contact temperature measurement of the outer surface of the cooking pot 20, and the temperature sensing component 50 detects the temperature of the outer surface of the cooking pot 20; the control method further comprises, in the pre-check mode, the controller controls the heating element 30 to start working to heat the cooking pot 20, after the preset time T2, the temperature measuring component 40 detects the temperature and feeds back the temperature value N1, and the temperature sensing component 50 detects the temperature of the cooking pot 20 and feeds back the temperature value N2, wherein the temperature value N2 is greater than or equal to the temperature value N1, and at this time, it is judged whether the difference between the temperature value N2-N1 is less than the preset temperature value N0; by comparing the difference between the temperature value N2 and the temperature value N1 with the size of the preset temperature value N0, it is further judged whether the liquid is heated within the preset time T2 and whether the temperature of the liquid is transmitted to the temperature measuring component 40, so as to achieve the effect of double judgment on whether the temperature measuring component 40 contacts the liquid, and then the state of the cooking mode is controlled based on the comparison result.
[0067] If so, it is determined that the cooking cover 10 forms a closing structure for the cooking cavity 201 and a portion of the temperature measuring component 40 is located in the cooking cavity 201 to be in contact with the liquid in the cooking cavity 201, and the temperature value N1 is determined to be the temperature value of the liquid in the cooking cavity 201. At this time, the controller controls to start the cooking mode or the controller controls the cooking mode to continue. In the cooking mode, the temperature measuring component 40 forms a structure for contact temperature measurement of the liquid in the cooking cavity 201.
[0068] If not, it is determined that the temperature measuring component 40 and the liquid in the cooking cavity 201 are not in contact with each other, and the temperature value N1 is not the temperature value of the liquid in the cooking cavity 201. At this time, the controller controls not to start the cooking mode or the controller controls the cooking mode to stop, or at this time the controller controls not to start the cooking mode and controls the sound module to feedback a prompt message or the controller controls the cooking mode to stop and controls the sound module to feedback a prompt message.
[0069] Specifically, for the part where the temperature measuring component 40 and the temperature sensing component 50 measure the temperature and feedback the temperature information, after the preset time T2, the temperature measuring component 40 detects the temperature and feedbacks the temperature value N1, and the temperature sensing component 50 detects the temperature of the cooking pot 20 and feedbacks the temperature value N2, wherein the temperature value N2 is greater than or equal to the temperature value N1, and at this time, it is determined whether the difference between the temperature values N2-N1 is less than the preset temperature value N0; it can be understood that after the preset setting T2, at this time, the temperature measuring component 40 and the temperature sensing component 50 are both To detect the temperature and feedback the temperature value, if the difference between the temperature values N2-N1 is less than the preset temperature value N0, it can be determined that the temperature measuring component 40 is in contact with the liquid to perform contact temperature measurement, the heating element 30 heats the cooking pot 20 to increase the temperature of the cooking pot 20, the cooking pot 20 transfers the temperature to the liquid to heat the liquid, and finally transfers the temperature to the temperature measuring component 40. At this time, it is determined that the temperature measuring component 40 achieves a heating effect in the state of contacting the liquid, thereby satisfying the difference between the temperature values N2-N1. If the value is less than the preset temperature value N0, the temperature difference between the temperature value N1 of the temperature measuring component 40 and the temperature value N2 of the temperature sensing component 50 is relatively small, so that the temperature is transferred from the cooking chamber 20 to the liquid and then to the temperature measuring component 40 through the liquid, so that the temperature measuring component 40 contacts the liquid and then detects the cooking temperature; if the difference between the temperature values N2-N1 is greater than or equal to the preset temperature value N0, it can be judged that the temperature measuring component 40 is not a structure that is in contact with the liquid for contact temperature measurement. At this time, the temperature of the liquid is not transferred to the temperature measuring component 40, resulting in a large temperature difference between the temperature value N1 of the temperature measuring component 40 and the temperature value N2 of the temperature sensing component 50, so that the difference between the temperature values N2-N1 is greater than or equal to the preset temperature value N0, resulting in the temperature measuring component 40 being unable to detect the temperature of the liquid, that is, unable to detect the cooking temperature, but detecting the temperature of the air in the cooking chamber 201, then it can be judged that the temperature measuring component 40 is not in contact with the liquid, and the temperature value N1 fed back is not the temperature value of the liquid.
[0070] Among them, when it is determined that the temperature measuring component 40 is in contact with the liquid for contact temperature measurement, the cooking mode can be controlled to start or the cooking mode can be controlled to continue. In the cooking mode, the temperature measuring component 40 forms a structure for contact temperature measurement of the liquid in the cooking cavity 201, thereby achieving the effect of precise temperature measurement and precise temperature control.
[0071] Among them, when it is determined that the temperature measuring component 40 and the liquid are not in contact with each other, the cooking mode can be controlled not to be started or the cooking mode can be controlled to stop; or at this time the controller controls not to start the cooking mode and controls the sound module to feedback a prompt message or the controller controls the cooking mode to stop and controls the sound module to feedback a prompt message.
[0072] Among them, the sound module can be a buzzer to send out an alarm sound to remind the user, or a voice device to send out a voice to remind the user, mainly to remind the user to determine that there is too little water in the cooking pot 20, and to add additional water to the cooking pot 20 so that the water level in the cooking pot 20 can form a structure of mutual contact with a part of the end position of the temperature measuring component 40.
[0073] Optionally, the size of the preset time T2 is affected by the heating power of the heating element 30 and the amount of water in the cooking cavity 201. In this embodiment, when the heating power of the heating element 30 is set to 1200 watts to 2000 watts, the preset time T2 is set to be in the range of 50 seconds to 180 seconds. After the cooker 1 works for the preset time T2, the temperature measuring component 40 detects the temperature and feeds back the temperature value N1, and the temperature sensing component 50 detects the temperature and feeds back the temperature value N2. Similarly, the size of the preset temperature value N0 is also affected by the heating power of the heating element 30 and the amount of water in the cooking cavity 201. Under the above definition, the preset temperature value N0 is set to be in the range of 30 degrees to 50 degrees. The difference between the temperature values N2-N1 is used to compare the size with the preset temperature value N0 to determine whether the temperature measuring component 40 is in contact with the liquid.
[0074] It can be understood that the heating element 30 directly or indirectly heats the cooking pot 20, so that the temperature value N2 is greater than or equal to the temperature value N1, and the temperature of the outer surface of the cooking pot 20 is always greater than or equal to the temperature of the liquid in the cooking cavity 201.
[0075] In this solution, in the cooking mode, after the preset time T3, when the temperature value E1 fed back by the temperature measuring component 40 is equal to the preset temperature value E0, the heating element 30 is controlled to enter the intermittent heating mode until the cooking mode ends. In this way, the temperature of the liquid is maintained at the preset temperature value when the heating element 30 is in the intermittent heating mode, thereby achieving a constant temperature cooking effect on the food.
[0076] Specifically, in the cooking mode, after the preset time T3, when the temperature value E1 fed back by the temperature measuring component 40 is equal to the preset temperature value E0, it can be understood that when the temperature value E1 detected by the temperature measuring component 40 reaches the preset temperature value E0 in the cooking mode, the preset temperature value E0 is also the preset cooking temperature value, that is, a reasonable preset temperature for cooking ingredients. At this cooking temperature, the ingredients can be effectively cooked. If the actual cooking temperature exceeds the preset cooking temperature value, it will result in poor cooking effect on the ingredients. Therefore, under the above conditions, the heating element 30 is controlled to enter the intermittent heating mode until the cooking mode ends. In the intermittent heating mode, the temperature value E1 of the liquid can be maintained below the preset temperature value E0, thereby achieving the effect of precise temperature control to cook the ingredients.
[0077] The intermittent heating mode is a mode in which the heating element 30 repeatedly cycles between stopping heating for a period of time and starting heating for a period of time to perform an intermittent heating effect, so as to keep the temperature of the liquid below a preset temperature value E0.
[0078] Optionally, the preset time T3 is set in the range of 20 minutes to 50 minutes. In this range, the heating element 30 can be in a continuous heating mode or an intermittent heating mode. When the temperature value E1 fed back by the temperature measuring component 40 reaches the preset temperature value E0, it means that the temperature of the liquid has reached the cooking temperature required in the cooking mode. The preset temperature value E0 can be set to a temperature value in the range of 55 degrees to 85 degrees. It can be understood that the setting of the preset temperature value E0 is set to different temperature values due to different ingredients. The cooking temperature needs to be set according to the different ingredients, that is, the preset temperature value E0 is set accordingly, thereby realizing the control of the temperature value E1 and achieving the precise temperature control effect in the cooking mode.
[0079] In the present solution, in the cooking mode, it also includes that after the preset time T4, the temperature measuring component 40 detects the temperature and feeds back the temperature value R1, and the temperature sensing component 50 detects the temperature and feeds back the temperature value R2, wherein the temperature value R2 is greater than or equal to the temperature value R1, and at this time, it is judged whether the difference between the temperature values R2-R1 is less than or equal to the preset temperature value R0; by comparing the corresponding difference between the temperature values R2-R1 with the size of the preset temperature value R0, it is possible to judge the temperature value of the liquid during the heating process, that is, the actual cooking temperature, so as to control the working state of the heating element 30 based on the cooking temperature.
[0080] If yes, the heating element 30 is controlled to stop working or to enter an intermittent heating mode, thereby preventing the temperature of the liquid from being too high and preventing the liquid from boiling.
[0081] If not, the heating element 30 is controlled to continue working to heat the liquid, so that the temperature value of the liquid can continue to rise, that is, the temperature value R1 continues to increase, until it is determined that the difference between the temperature values R2-R1 is less than or equal to the preset temperature value R0, the heating element 30 is controlled to stop working or the heating element 30 is controlled to enter the intermittent heating mode, so as to achieve the control of the temperature of the liquid, that is, the cooking temperature.
[0082] Specifically, in the cooking mode, it also includes that after the preset time T4, the temperature measuring component 40 detects the temperature and feeds back the temperature value R1, and the temperature sensing component 50 detects the temperature and feeds back the temperature value R2, wherein the temperature value R2 is greater than or equal to the temperature value R1, and at this time, it is determined whether the difference between the temperature values R2-R1 is less than or equal to the preset temperature value R0; that is, after the preset time T4, T4 can be set to be in the range of 25 minutes to 50 minutes, at this time, the temperature measuring component 40 and the temperature sensing component 50 both detect the temperature and feed back the temperature value, and when the difference between the temperature values R2-R1 is less than or equal to the preset temperature value R0, the temperature value N1 of the temperature measuring component 40 and the temperature value N2 of the temperature sensing component 50 are equal to or equal to the preset temperature value R0. 2 are relatively close in size, and the temperature difference between the two is relatively small, which means that the temperature of the liquid is close to the cooking temperature required in the cooking mode. At this time, the food can be cooked at the current cooking temperature, and the heating element 30 is controlled to stop working or the heating element 30 is controlled to enter the intermittent heating mode to keep the temperature of the liquid at the preset temperature value R0 to cook the food; it can be understood that when the difference between the temperature values R2-R1 is greater than the preset temperature value R0, the temperature difference between the temperature value N1 of the temperature measuring component 40 and the temperature value N2 of the temperature sensing component 50 is still relatively large, and the temperature value W1 of the liquid is relatively low, and the heating element 30 needs to be continuously heated to keep the liquid warm.
[0083] Optionally, the preset temperature value R0 is set in the range of 20 degrees to 30 degrees, so that the temperature value N1 of the temperature measuring component 40 and the temperature value N2 of the temperature sensing component 50 are relatively close, and the temperature difference between the two is relatively small. At this time, the working state of the heating element 30 can be better controlled to keep the temperature of the liquid at the current cooking temperature to cook the ingredients, which can better improve the cooking taste of the ingredients.
[0084] Among them, if it is judged that the difference between the temperature values R2-R1 is less than or equal to the preset temperature value R0, the heating element 30 is controlled to stop working or the heating element 30 is controlled to enter the intermittent heating mode, and the temperature measuring component 40 and the temperature sensing component 50 continue to measure the temperature. When the difference between the temperature values R2-R1 is greater than the preset temperature value R0, the heating element 30 is controlled to resume heating to heat the liquid, so that the temperature of the liquid can be maintained at the preset temperature value R0 to cook the food, thereby achieving a constant temperature cooking effect for the food.
[0085] Among them, if it is judged that the difference between the temperature values R2-R1 is greater than the preset temperature value R0, the heating element 30 is controlled to continue working, until it is judged that the difference between the temperature values R2-R1 is less than or equal to the preset temperature value R0, the heating element 30 is controlled to stop working or the heating element 30 is controlled to enter the intermittent heating mode, so that the temperature of the liquid can be maintained at the preset temperature value R0 to cook the food, thereby achieving a constant temperature cooking effect for the food.
[0086] In this solution, with respect to the structural part of the cooking device 1, the temperature measuring component 40 realizes the effect of switching between the protruding structure and the folded structure. When in the protruding structure, the liquid in the cooking pot 20 can be contact-measured for temperature. When in the folded structure, the temperature measuring component 40 does not form a structure that blocks the user from performing cooking operations on the cooking cavity 201. The specific structure is as follows:
[0087] When the cooking cover 10 is in an open structure with respect to the cooking cavity 201, the temperature measuring component 40 is in a folded structure on the cooking cover 10 so that the temperature measuring component 40 does not contact the liquid in the cooking cavity 201. When the cooking cover 10 is opened, the cooking cover 10 drives the temperature measuring component 40 to separate from the cooking cavity 201 and enter the external space of the cooking pot 20, so that the temperature measuring component 40 cannot contact the liquid in the cooking cavity 201, so that the temperature measuring component 40 and the liquid do not contact each other. At the same time, the temperature measuring component 40 is formed in a folded structure on the cooking cover 10, so that the temperature measuring component 40 does not constitute a protruding structure relative to the bottom end surface of the cooking cover 10, but constitutes a folded structure to be folded and placed on the cooking cover. 10; when the cooking cover 10 forms a closing structure for the cooking cavity 201, the temperature measuring component 40 is in a convex structure on the cooking cover 10 to form a structure in which the temperature measuring component 40 and the liquid in the cooking cavity 201 are in contact with each other, so that the temperature measuring component 40 can detect the temperature of the liquid in the cooking cavity 201. When the cooking cover 10 is closed, the temperature measuring component 40 rotates with the cooking cover 10 to enter the cooking cavity 201 from the external space of the cooking chamber 20, thereby realizing a structure in contact with the liquid in the cooking cavity 201. The contact structure forms a contact temperature measurement effect. The cooker 1 can control the working state based on the temperature measurement structure to achieve a cooking effect of precise temperature control of the food.
[0088] Among them, the temperature measuring component 40 is configured to be switchable between a raised structure and a folded structure, that is, when the temperature measuring component 40 is needed to contact the liquid for temperature measurement, the temperature measuring component 40 will switch and deform from the folded structure to the raised structure; when the temperature measuring component 40 is not needed to contact the liquid for temperature measurement, the temperature measuring component 40 will switch and deform from the raised structure to the folded structure, so that the temperature measuring component 40 is in the folded structure to facilitate the user to perform cooking operations on the cooking cavity 201, such as adding water, adding ingredients, stirring, putting in or taking out ingredients and other cooking operations.
[0089] The switching structure of the temperature measuring component 40 between the protruding structure and the folded structure can be specifically configured as follows:
[0090] In the first structural mode, a flexible portion with a soft structure is provided on the temperature measuring component 40 so that when the flexible portion is deformed, the temperature measuring component 40 can switch between a convex structure and a folded structure. The flexible portion can be set to a soft and deformable structure, or a soft and deformable structure that can reset and rebound under deformation. When the user applies an external force to the temperature measuring component 40, the flexible portion of the temperature measuring component 40 is deformed so that the temperature measuring component 40 is bent from a convex structure and gradually folded to form a folded structure. Under the folded structure of the temperature measuring component 40, when the user applies an external force again, the temperature measuring component 40 can be deformed from the folded knot to a convex structure. Alternatively, when the force applied to the temperature measuring component 40 disappears, the flexible portion is elastically reset and deformed to switch from the folded structure to a convex structure. This can achieve the switching effect of the temperature measuring component 40 between the convex structure and the folded structure.
[0091] Among them, a clamping structure can be set between the cooking cover 10 and the temperature measuring component 40, so that the temperature measuring component 40 is clamped on the cooking cover 10 in the folded structure and maintained in the folded structure. When the temperature measuring component 40 is separated from the clamping structure, the temperature measuring component 40 can be switched from the folded structure to a protruding structure; or a magnetic attraction structure can be set, such as a magnetic part is set on the cooking cover 10 to generate a magnetic attraction force on the temperature measuring component 40 to magnetically attract the temperature measuring component 40 to the cooking cover 10 and maintain it in the folded structure.
[0092] In the second structural mode, the temperature measuring component 40 is set to be rotatably mounted on the cooking cover 10 so that when the temperature measuring component 40 rotates, it can switch between the protruding structure and the folded structure. The upper end of the temperature measuring component 40 is rotatably mounted on the cooking cover 10, so that the temperature measuring component 40 can perform independent rotational movement relative to the cooking cover 10. For the power of the rotational movement of the temperature measuring component 40, a motor can be set to provide power for driving, or the user can manually apply an external force to drive it, both of which can achieve the switching effect of the temperature measuring component 40 forming a switching effect between the protruding structure and the folded structure through rotational movement.
[0093] In order to further improve the accuracy and stability of the temperature measurement by the temperature measuring component 40 and prevent the end position of the temperature measuring component 40 from being blocked by the adhesion or contact of the food, in this solution, when the temperature measuring component 40 is in a convex structure, the temperature measuring component 40 is in a convex structure extending toward the cooking cavity 201, and when the temperature measuring component 40 is blocked by the food, the temperature measuring component 40 can be moved in a direction away from the food or in a direction toward the side wall of the cooking cavity 201 to at least make the end position of the temperature measuring component 40 away from the food; a part of the main body of the temperature measuring component 40 can be set to be soft and deformable In the structure, when the cooking cover 10 is used to cover and close the cooking cavity 201, the end of the temperature measuring component 40 contacts the food. At this time, the food forms a blocking force, and under the action of the blocking force, the end of the temperature measuring component 40 is moved toward the side wall of the cooking cavity 201 to at least keep the end of the temperature measuring component 40 away from the food. This can prevent the food from adhering to the end of the temperature measuring component 40, ensure that the end of the temperature measuring component 40 is kept in a clean state and kept in direct contact with the liquid for temperature measurement, thereby improving the accuracy and stability of temperature measurement.
[0094] In the present embodiment, when the cooking cover 10 forms an open structure with respect to the cooking cavity 201 and the temperature measuring component 40 is in a folded structure, the temperature measuring component 40 is configured to be a structure that does not block the user from performing cooking operations on the cooking cavity 201. When the cooking cover 10 forms an open structure with respect to the cooking cavity 201, the temperature measuring component 40 is set to be in a folded structure. At this time, the temperature measuring component 40 is in a folded structure relative to the bottom end surface of the cooking cover 10 and does not form a convex structure. In this way, the temperature measuring component 40 does not form a structure that blocks the user from performing cooking operations on the cooking cavity 201. It can be understood that if the temperature measuring component 40 is in a convex structure when the cooking cover 10 forms an open structure with respect to the cooking cavity 201, the temperature measuring component 40 will form a structure that blocks the user from manually performing cooking operations on the cooking cavity 201, making it inconvenient for the user to perform cooking operations, and at the same time, it is easy to form a collision effect on the temperature measuring component 40, which is easy to cause the temperature measuring component 40 to be damaged by collision, resulting in reduced safety and stability of the temperature measuring component 40.
[0095] In order to improve the accuracy of judging whether the temperature measuring component 40 is in contact with the liquid, in the present solution, in the cooking mode, it also includes controlling to start the pre-check mode multiple times, and judging multiple times through the pre-check mode whether the temperature measuring component 40 is in contact with the liquid in the cooking cavity 201 in the cooking mode, wherein if at least one of the multiple judgments shows that the temperature measuring component 40 and the liquid in the cooking cavity 201 are not in contact with each other, the cooking mode is controlled to stop; that is, after the controller controls the cooking mode to start, it also controls to start the pre-check mode multiple times, and judging whether the temperature measuring component 40 is in contact with the liquid in the cooking cavity 201 through the multiple pre-check modes. The structures in contact with each other are detected and judged multiple times to ensure that during the cooking mode, the temperature measuring component 40 is always in contact with the liquid through detection and judgment. If during the cooking mode, it is determined once that the temperature measuring component 40 and the liquid in the cooking cavity 201 are not in contact with each other, the cooking mode is controlled to stop, ensuring that the temperature measuring component 40 is in contact with the liquid during the entire working time of the cooking mode, thereby effectively realizing the control of the cooking mode state or the working state of the heating element 30 based on the temperature measuring structure of the temperature measuring component 40, and realizing accurate temperature measurement and accurate temperature control of the food for cooking.
[0096] And / or, in the present embodiment, the cooking mode is set to a low-temperature cooking mode. In the low-temperature cooking mode, the working state of the heating element 30 is controlled at least by the temperature of the liquid in the cooking cavity 201 detected by the temperature measuring component 40, so that the liquid in the cooking cavity 201 is always in a non-boiling state. The controller controls the working state of the heating element 30 based on the temperature value detected and fed back by the temperature measuring component 40. The working state of the heating element 30 includes starting heating, stopping heating, continuous heating, intermittent heating, increasing or reducing power heating, etc., and then the temperature of the liquid in the cooking cavity 201 is controlled based on the working state of the heating element 30 to achieve the effect of precise temperature control; wherein, in the low-temperature cooking mode, different temperature values can be set based on different ingredients, and the upper limit of the temperature value of the liquid can be set to 85 degrees, so that the temperature value of the liquid detected by the temperature measuring component 40 is always less than or equal to 85 degrees, thereby achieving the effect of low-temperature cooking, forming a state in which the liquid never boils, and meeting the low-temperature cooking requirements of the ingredients.
[0097] And / or, in the present solution, with respect to the position setting portion of the temperature measuring component 40, in order to further prevent the temperature measuring component 40 from being adhered to or contacting the food and in order to further improve the accuracy of the temperature measuring component 40 in measuring the temperature, it is mainly set that the distance from the end position of the temperature measuring component 40 in the radial direction of the cooking cavity 201 to the side wall surface of the cooking cavity 201 is less than half of the distance from the end position of the temperature measuring component 40 in the radial direction of the cooking cavity 201 to the central axis position of the cooking cavity 201, so that the end position of the temperature measuring component 40 is relatively far away from the food placed at the center position of the cooking cavity 201, and the end position of the temperature measuring component 40 is relatively close to the side wall surface position of the cooking cavity 201, forming a position relatively far away from the cooking cavity 201. As for the structure of the position where the central axis is located, it can be understood that when food is added into the cooking cavity 201, the food is generally placed at the position where the central axis of the cooking cavity 201 is located or at a position near the position where the central axis is located. In this scheme, the position where the temperature is measured at the end position of the temperature measuring component 40 is relatively far away from the central axis position of the cooking cavity 201, so that when the cooking cover 10 is used to cover and close the cooking cavity 201, the temperature measuring component 40 is not easy to be inserted into or contact the food, which can ensure that the temperature measuring component 40 is not blocked by the adhesion or contact of the food. In this way, the end position of the temperature measuring component 40 can be kept in a relatively clean state to contact the liquid for temperature measurement, which greatly improves the accuracy and reliability of the temperature measurement by the temperature measuring component 40.
[0098] It is understandable that when the end position of the temperature measuring component 40 contacts the food, the food will form an adhesion or contact effect on the end position of the temperature measuring component 40, causing the temperature detected by the end position of the temperature measuring component 40 to be affected by the food, resulting in a temperature measurement deviation problem. The end position of the temperature measuring component 40 is kept in a clean state for temperature measurement, which not only makes the temperature measurement more accurate, but also makes the temperature measuring component 40 easier to maintain and clean, and the temperature measuring component 40 will not be blocked by the blocking force due to contact with the food, resulting in collision damage, thereby improving the safety and reliability of the temperature measuring component 40.
[0099] Optionally, the distance from the end position of the temperature measuring component 40 to the side wall of the cooking cavity 201 in the radial direction of the cooking cavity 201 is set to be smaller than one third of the distance from the end position of the temperature measuring component 40 to the central axis position of the cooking cavity 201 in the radial direction of the cooking cavity 201. At this time, the end position of the temperature measuring component 40 is relatively farther away from the central axis position of the cooking cavity 201, and further relatively closer to the side wall position of the cooking cavity 201, so that the probability of the temperature measuring component 40 contacting the food is smaller, and the accuracy and stability of the temperature measurement of the temperature measuring component 40 are better improved.
[0100] In this solution, since the cooking mode is a low-temperature cooking mode, the liquid in the cooking cavity 201 will not boil, so that the food in the cooking cavity 201 will remain in the current position and will not move. The food will not move and contact the end position of the temperature measuring component 40 due to the boiling of the liquid. It can also ensure that the end position of the temperature measuring component 40 can always contact the liquid for temperature measurement, effectively eliminating the interference of the food on the temperature measurement of the temperature measuring component 40 and eliminating the problem of temperature measurement deviation.
[0101] In the present solution, the specific structural part of the temperature measuring component 40 includes a temperature measuring piece, and the temperature measuring piece is configured to be made of a metal material, such as stainless steel. The end position of the temperature measuring piece is configured as the end position of the temperature measuring component 40, and the end position of the temperature measuring piece contacts the liquid in the cooking cavity 201 to achieve a temperature measurement effect on the liquid.
[0102] Among them, in this scheme, the temperature measuring component 40 also includes a main body, which is connected to the temperature measuring component. The main body is configured to be a structure for switching between the folding structure and the protruding structure, and drives the temperature measuring component to perform synchronous movement to achieve switching between the protruding structure and the folding structure. The flexible part can be set on the main body, or the main body can be configured to be a structure that is rotatably mounted on the cooking cover 10, so that the main body can achieve rotational movement when subjected to external force such as manual operation force of the user to form a switching effect between the folding structure and the protruding structure.
[0103] In this solution, the temperature sensing component 50 is mainly located below the cooking pot 20. When the cooking pot 20 is installed and placed in place, the temperature sensing piece on the temperature sensing component 50 contacts the bottom surface of the outer surface of the cooking pot 20 to detect the temperature of the cooking pot 20. The temperature sensing component 50 is not configured to contact the liquid, so that the temperature sensing component 50 does not measure the temperature of the liquid. The temperature sensing piece is set to a metal material, such as stainless steel or aluminum.
[0104] Among them, the temperature sensing component 50 and the temperature measuring component 40 are both electrically connected to the controller, mainly the temperature sensing component and the temperature measuring component are electrically connected to the controller respectively, and respectively realize signal feedback transmission between the controller. At the same time, the heating component 30 is also electrically connected to the controller, so that the controller controls the working state of the heating component 30 based on the information feedback received from the temperature sensing component and the temperature measuring component, such as the heating component 30 starts heating, stops heating, performs intermittent heating, etc., so as to achieve precise temperature control effect in the cooking mode.
[0105] In this solution, in the low-temperature cooking mode, the temperature of the liquid in the cooking cavity 201 is mainly controlled to be maintained at a certain temperature point below 85 degrees. Specific temperature points can be set according to different ingredients to achieve low-temperature cooking effects on meat ingredients, which can be beef, chicken, etc.
[0106] The cooker 1 of the present solution can be a rice cooker, a pressure cooker, a steamer, etc. It only needs to have the function of steaming and configure the present solution to set structures such as the temperature measuring component 40 and the temperature sensing component 50 to achieve the low-temperature cooking function of the cooker 1.
[0107] Working principle: The cooking device 1 of the present invention is used to cook food materials. Food materials and water are placed in the cooking cavity 201. The food materials are mainly meat food materials. When the cooking device 1 is started, it includes starting a pre-check mode. The pre-check mode is used to determine whether the temperature measuring component 40 forms a contact structure with the liquid, i.e., the water, in the cooking cavity 201, and then determine whether the temperature detected by the temperature measuring component 40 is the temperature of the liquid, that is, whether it is the actual cooking temperature. At the same time, the temperature sensing component 50 can be combined to jointly realize the determination and detection of whether the temperature measuring component 40 is in contact with the liquid through the temperature sensing component 50 and the temperature measuring component 40. In the cooking mode, mainly in the low-temperature cooking mode, the temperature measuring component 40 contacts the liquid in the cooking cavity 201 in real time. The temperature of the body is measured to detect the actual cooking temperature, and the working state of the heating element 30 or the state of the cooking mode is controlled based on the temperature information detected by the temperature measuring component 40, so as to achieve the effect of precise temperature control, so that the liquid in the cooking cavity 201 can always be maintained at the required temperature under the low-temperature cooking function, forming a state where the liquid will never boil, which can effectively improve the taste of low-temperature cooking ingredients; in this solution, the temperature measuring component 40 can effectively detect the temperature of the liquid. The setting of the temperature measuring component 40 makes the reliability and accuracy of its temperature detection higher. At the same time, it will not form a structure that prevents the user from performing cooking operations on the cooking cavity 201, which is convenient for the user to perform cooking operations, greatly improving the user experience.
[0108] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made in form and detail without departing from the spirit and scope of the present invention, all of which are within the protection scope of the present invention.
