Description

Technical Field

[0001] The invention relates to a cooking stove, and in particular to a pot identification method and structure, and a cooking stove with a pot identification function. Background Art

[0002] The bottom of the general-purpose cookware on the market is flat. Due to the preparation of the cookware, this type of stove is basically sold as a separate pot and stove. Since it is impossible to identify whether it is a non-matching cookware, the stove cannot accurately control the heating and temperature rise, which can easily cause the cookware to burn out and is more likely to affect the stove circuit board.

[0003] This type of stove appliance is usually equipped with a temperature detection device to directly (set a temperature detection point extending to the upper surface of the top of the casing) or indirectly (set a temperature detection point on the lower surface of the top of the casing) detect the temperature of the bottom of the pot. The cooking temperature of the food in the pot is confirmed by comparing the detected temperature value with the target / preset temperature value, so as to judge and adjust the operation of the heating module.

[0004] As mentioned above, when users can use pots of different specifications / materials on this type of stove appliance, due to the different materials / thicknesses of the pots, there will be a large deviation between the temperature inside the pot and the detection temperature of this type of stove appliance (the temperature on the outside of the bottom of the pot). The most critical thing is that the difference in deviation values ​​caused by different pots makes it impossible to achieve precise temperature control and obtain the accurate cooking temperature in the pot, resulting in the cooking effect not being guaranteed.

[0005] Of course, there are also stove appliances that are sold together with pots. In this way, when setting the temperature probe reading, the manufacturer uses the inner and outer side deviation values ​​of the bottom of the pot as compensation for the reading, so as to convert it to the temperature inside the pot, and achieve precise temperature control of the cooking environment / area; however, this type of product does not have the function of identifying and matching pots, and can only be judged manually. It is impossible to accurately confirm whether it is a matching pot, and the above-mentioned problem will also occur. Summary of the invention

[0043] Now, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] Based on the fact that the bottom of existing pots is a whole flat bottom, the present invention provides a pot identification method for a cooker that realizes the cooking function by heating in the form of electric heating, wherein the cooker comprises a pot and a stove, wherein the stove is provided with a main control panel and a temperature measuring point, and the bottom of the pot matched with the cooker of the present invention is a non-flat plane.

[0045] Combined with Figure 1 , attached Figure 1 : is a flow chart of a method for identifying a cookware according to the present invention, wherein the method for identifying a cookware comprises the following steps:

[0046] S10: presetting a predetermined heating area of ​​the stove, wherein the predetermined heating area includes: a first stove heating area and a second stove heating area;

[0047] Presetting the predetermined temperature measurement area of ​​the matching cooker bottom, the predetermined temperature measurement area includes: a first temperature measurement area corresponding to the first stove heating area, and a second temperature measurement area corresponding to the second stove heating area;

[0048] A temperature measuring device is pre-arranged in the stove heating zone, a first temperature measuring device is arranged in the first stove heating zone, and a second temperature measuring device is arranged in the second stove heating zone,

[0049] In the present invention, the first temperature measuring zone of the cookware matched with the stove is provided with a first pot bottom structure, and the second temperature measuring zone is provided with a second pot bottom structure. There is a predetermined gap between the first pot bottom structure and the first temperature measuring device, and the second pot bottom structure is in contact with the second temperature measuring device. The first temperature measuring device measures the spatial temperature at the first temperature measuring zone, and the second temperature measuring device measures the pot bottom temperature at the second temperature measuring zone.

[0050] S20: placing the pot in the heating area of ​​the stove, turning on the electric heating function of the stove to heat the stove for a predetermined time; wherein the predetermined time for turning on the electric heating function of the stove to heat the stove is 10-60s.

[0051] S30: By setting temperature measuring points in different predetermined heating areas on the cooker, the temperatures of different predetermined temperature measuring areas on the bottom of the cooker are correspondingly measured, and by the temperature difference between the different predetermined temperature measuring areas, it is determined whether the cooker currently placed on the cooker is a matching cooker.

[0052] The method of judging whether the pot currently placed on the cooker is a matching pot specifically comprises the following steps: when it is determined that the temperature difference between the first temperature measuring area and the second temperature measuring area is greater than or equal to a preset temperature difference threshold, the pot currently placed on the cooker is judged to be a matching pot; otherwise, the pot currently placed on the cooker is judged not to be a matching pot.

[0053] Specifically, the first temperature measuring device reads the temperature of the first temperature measuring zone after heating, and the second temperature measuring device reads the temperature of the pot bottom in the second temperature measuring zone after heating. Based on the gap between the first pot bottom structure of the matching cookware and the first temperature measuring device, the temperature measured by the first temperature measuring device has a certain temperature difference with the temperature measured in the second temperature measuring zone. Therefore, a temperature difference threshold is preset. When it is determined that the temperature difference between the first temperature measuring zone and the second temperature measuring zone is greater than or equal to the preset temperature difference threshold, it is judged as a matching cookware. Otherwise, it is judged as an unmatched cookware.

[0054] In this embodiment, after determining that both are matching cookware, the following steps are further included:

[0055] S40: Execute a preset cooking operation according to the judgment result of the cookware.

[0056] Specifically, when it is determined that the cooker is not a matching cooker, the cooker performs an error reminder operation, which may include emitting a buzzer reminder, entering a standby state, flashing a light reminder, etc. If it is determined that the cooker is a matching cooker, the read temperature is converted into the temperature inside the cooker, and operations such as automatic cooking and adjusting the fire size of the cooker are performed.

[0057] The pot identification method sets temperature measuring points at different positions in the heating area of ​​the stove, and can judge whether the placed pot is a matching pot based on the temperature difference. Based on the one-to-one correspondence between the matching pot and the stove, precise temperature control can be achieved to obtain the accurate cooking temperature in the pot to ensure the correct execution of the automatic cooking program. At the same time, in the case of a mismatched pot, an error reminder operation is also performed to remind the user to replace it with a matching pot, so as to reduce the risk of damage to the cooker due to the mismatch between the pot and the stove.

[0058] In another embodiment of the present invention, Figure 2 And attached Figure 3A pot identification structure is provided, which is applied to a cooker that realizes a cooking function by heating in the form of electric heating. The cooker includes a pot 10 and a stove 20, and the pot identification structure includes: a first temperature measuring device and a second temperature measuring device arranged in a heating area of ​​the stove, and a first pot bottom structure and a second pot bottom structure arranged at the bottom of the pot; wherein the first pot bottom structure is configured so that when the pot 10 is placed on the stove 20, there is a predetermined gap between the first temperature measuring device and the first pot bottom structure, and the first temperature measuring device is used to measure the temperature of the space within the predetermined gap; the second pot bottom structure is configured so that when the pot 10 is placed on the stove 20, the second temperature measuring device is in contact with the second pot bottom structure, and the second temperature measuring device is used to measure the pot bottom temperature of the second pot bottom structure; the pot 10 is placed in the heating area of ​​the stove 20, the electric heating function of the stove 20 is turned on to heat the stove for a predetermined time, and the temperature difference between the temperatures read by the first temperature measuring device and the second temperature measuring device is used to determine whether the pot currently placed on the stove is a matching pot 10.

[0059] By configuring the first pot bottom structure to leave a predetermined gap with the first temperature measuring device, and configuring the second pot bottom structure to contact the second temperature measuring device, and utilizing the temperature difference between the corresponding temperature readings of the first temperature measuring device and the second temperature measuring device, accurate identification of the pot 10 is achieved, ensuring one-to-one application of the stove 20 and the pot 10, and providing a basis for accurate temperature control of the stove 20, thereby effectively avoiding the problem of poor taste of cooked food due to wrong selection of the pot, and at the same time avoiding damage to the cooking device caused by mismatch between the pot 10 and the stove 20.

[0060] In this embodiment, the cooker 20 includes a housing 21, on which a main control board 22 is disposed for setting a heating time, a heating temperature, and performing a cooking operation. The first temperature measuring device and the second temperature measuring device include temperature sensors. The first temperature measuring device and the second temperature measuring device are electrically connected to the main control board 22.

[0061] The first pot bottom structure is a groove 11 arranged at the bottom of the pot 10, and the second pot bottom structure is a plane. There is a predetermined gap between the first temperature measuring device and the bottom of the groove 11 of the first pot bottom structure. The width of the predetermined gap is 0.5-5mm. The depth of the groove can be preferably 0.5-5mm. The groove 11 of the pot bottom can be a circular or annular groove 11 arranged on the contact surface between the pot bottom and the stove 20, so that there is a certain gap between the bottom of the groove 11 and the first temperature measuring device, and the predetermined gap is less than the depth of the pot bottom thickness, and the contact surface between the pot bottom and the cooked food is a plane. The circular or annular groove 11 can be adapted to the application scenario of matching the pot 10 to rotate or place in different directions on the stove 20. Alternatively, in another embodiment, the groove 11 can also be recessed and protruded inwardly from the inside of the pot bottom, and the depth of the gap between the bottom of the groove 11 and the first temperature measuring device is greater than the thickness of the pot bottom.

[0062] The first temperature measuring device measures the temperature in the space formed by the groove 11, and the second temperature measuring device measures the temperature at the plane of the bottom of the pot. Based on the temperature difference between the readings of the first temperature measuring device and the second temperature measuring device, it is identified whether the pot 10 currently placed on the stove 20 is a matching pot 10. Since the bottom of the pot of the market product is a whole flat bottom, after heating for a certain period of time, if the readings of the first temperature measuring device and the second temperature measuring device are basically the same, it can be identified as a non-matching pot. If the readings of the first temperature measuring device and the second temperature measuring device have a predetermined temperature difference or are close to the predetermined temperature difference, it can be identified as a matching pot 10. Then, the temperature measured at the bottom of the matching pot 10 can be accurately converted to determine the temperature inside the pot 10, providing a strong guarantee for realizing automatic cooking, and can accurately execute automatic cooking situations.

[0063] In one embodiment, the groove 11 is located at the center of the bottom of the cookware 10 , and / or the second temperature measuring device is arranged in a ring shape around the center line of the cookware 10 to facilitate alignment of the first temperature measuring device and the groove 11 .

That is, the first support column 24 is provided at the position of the pot groove 11 of the stove 20, and when the matching pot 10 is placed on the stove 20, the provided first temperature measuring device is not in contact with the groove 11. Preferably, the second support columns 25 are evenly distributed on the stove 20, and there are 3 second support columns 25. In one embodiment, the first support column 24 can be provided as 1, located at the center of the groove 11; or, the first support columns 24 can be 3, and the 3 first support columns 24 are evenly distributed.

[0065] In other embodiments, the first stove heating zone and the second stove heating zone are respectively provided with a first support ring and a second support ring, at least one of the first temperature measuring devices is provided in the first support ring, and at least one of the second temperature measuring devices is provided in the second support ring. That is, the first support ring is provided at the position of the cooker groove 11 of the stove 20, and when the matching cooker 10 is placed on the stove 20, the first temperature measuring device provided on the first support ring is not in contact with the groove 11; the second support ring is provided around the periphery of the first support ring, and the second support ring is in contact with the bottom of the cooker 10.

[0066] The cooking device uses electric heating to heat the food and can be an induction cooker, a thermistor, an electric ceramic cooker, an infrared cooker, etc. A heating element 23 is provided in the housing 21, and the electric heating method used can be an IH heating coil, a resistance heater, or an infrared heater.

[0067] The pot recognition structure and the cooker with the pot 10 recognition function of the present invention can judge the matching pot 10 by comparing the temperature difference between the first temperature measuring device and the second temperature measuring device after heating, thereby realizing the pot recognition function and providing a basis for the precise temperature control of the cooker; the temperature read by the first temperature measuring device and the second temperature measuring device is converted to the temperature inside the pot 10, so as to realize the precise temperature control of the cooking environment / part, obtain the accurate cooking temperature in the pot, ensure the cooking effect, and improve the user experience.
