Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, specifically to a heating cooking stove and its control method, and cooking equipment. Background Technology

[0002] Currently, when cooking utensils are heated on a flat stovetop, the pot vibrates as the food inside heats up and the water boils. After heating for a period of time, the pot's position shifts significantly, leading to reduced heating efficiency or uneven heating of the food. Existing solutions to this problem involve increasing the roughness of the stovetop surface to increase friction and reduce pot displacement. While this has some effect, it does not effectively improve heating efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a heating cooking stove and its control method and cooking equipment, which can detect the misalignment of the pot in a timely manner, and adjust the position of the heating source to keep the pot and the heating source aligned in the center, thereby effectively improving the heating effect and increasing the heating efficiency, so as to solve the technical problems mentioned in the background above.

[0004] In a first aspect, the present invention provides a heating cooking stove, comprising:

[0005] The receiving surface is used to support heated cooking utensils.

[0006] A heating unit is located below the receiving surface and is used to heat the cooking appliance to be heated;

[0007] The motion mechanism, connected to the heating unit, is used to drive the heating unit to move;

[0008] A position detection device, installed on the receiving surface, is used to detect the position signal of the cooking appliance to be heated;

[0009] The controller is connected to the position detection device and the motion mechanism respectively. It is used to determine the current position of the cooking appliance to be heated based on the position signal detected by the position detection device, and drive the motion mechanism to move the heating unit to the current position to heat the cooking appliance.

[0010] The heating and cooking stove provided by this invention can detect the misalignment of the cooking appliance in real time by using a position detection device. By controlling the motion mechanism to adjust the position of the heating unit, the cooking appliance and the heating unit are aligned. Maintaining the alignment of the two during the heating process can effectively improve the heating effect and increase the heating efficiency.

[0011] In one optional embodiment, the position detection device includes: a plurality of position detection units, each position detection unit being distributed at different positions on the surface of the receiving surface.

[0012] This invention improves the accuracy of position detection of the cooking appliance to be heated by arranging several position detection units at different positions on the receiving surface, thereby further enhancing heating efficiency.

[0013] In one optional implementation, with the center of the preset standard heating area on the receiving surface as the center, each position detection unit is set along the radial direction outside the preset standard heating area, which is the area covered by the heating unit at the initial position.

[0014] This invention reduces the number of position detection units required by placing each unit along the radial direction of the outer edge of a preset standard heating area. This accelerates the calculation of the current position of the cooking appliance to be heated, enabling rapid acquisition of the appliance's offset status and improving heating efficiency. Furthermore, it avoids interference or heating of the detection units by the heating area, reducing the risk of damage and ensuring their normal operation.

[0015] In one alternative implementation, the positions of each position detection unit are arranged according to one of the following structures: an annular angular matrix, a rectangular coordinate matrix, and a polar coordinate matrix.

[0016] This invention arranges the position detection units based on the structure of a circular annular angular matrix, a rectangular coordinate matrix, and a polar coordinate matrix, which can quickly obtain the coordinates of the cooking appliance to be heated, and the position calculation process is simple and convenient.

[0017] In one alternative implementation, the spacing between the position detection units in the same radial direction decreases as the radius increases.

[0018] The present invention sets up detection units in the same radial direction with the interval decreasing as the radius increases. This can meet the requirements for the number and accuracy of detection units both inside and outside the heating area, and ensure the detection accuracy of the central heating area while reducing the overall number of detection units.

[0019] In one alternative implementation, the position detection unit includes one or more of the following: an electromagnetic induction sensor, a laser sensor, a radar sensor, an infrared sensor, and a radio frequency identification sensor.

[0020] This invention employs multiple position detection units, which can effectively improve the detection accuracy of cooking appliances to be heated.

[0021] In one optional implementation, the heating unit is heated by electromagnetic heating.

[0022] This invention uses electromagnetic heating, which can reduce heat transfer loss during the heating process of cooking utensils and effectively improve heating efficiency.

[0023] In a second aspect, the present invention provides a method for controlling a heating cooking stove, based on the heating cooking stove of the first aspect, the method comprising:

[0024] Acquire the position signal detected by the position detection device;

[0025] Based on the position signal, determine the current position of the cooking appliance to be heated;

[0026] The motion mechanism is driven to move the heating unit to the current position to heat the cooking appliance.

[0027] The heating cooking stove control method provided by this invention can detect the position of the cooking appliance to be heated in real time, promptly identify the misalignment, and improve the heating effect of the heating cooking stove by adjusting the position of the heating unit; during the heating process, the cooking appliance to be heated and the heating unit are always kept aligned, thereby improving the heating efficiency.

[0028] In one optional embodiment, the position detection device includes: a plurality of position detection units, each position detection unit being distributed at different positions on the surface of the receiving surface, for acquiring position signals detected by the position detection device, including:

[0029] Obtain the detection results of each detection unit at each location;

[0030] The screening and detection results are the set of target location detection units where cooking appliances to be heated exist;

[0031] A position signal is generated based on the set position corresponding to each target position detection unit in the target position detection unit set.

[0032] The position signal of this invention is generated by detecting the cooking appliance to be heated based on several detection units arranged at different positions on the surface of the receiving surface, which can effectively characterize the position information of the cooking appliance to be heated.

[0033] In one optional implementation, the screening detection result is a set of target location detection units indicating the presence of a cooking appliance to be heated, including:

[0034] Obtain the set position of each location detection unit;

[0035] Using the center of the preset standard heating area on the receiving surface as the center, the detection units at each position are grouped along the radial direction according to their respective positions;

[0036] The detection results of each position detection unit in each group are extracted sequentially along the radial direction until the first detection result is obtained that the first position detection unit has a cooking appliance to be heated;

[0037] Centered on the first position detection unit, the detection results of other adjacent position detection units are traversed until all position detection units whose detection results indicate the presence of cooking appliances to be heated are selected, thus forming a target position detection unit set.

[0038] The present invention groups the position detection units and, after determining the first position detection unit of the cooking appliance to be heated, it traverses and filters the detection results of the other adjacent position detection units. This process is simple and convenient, and can quickly obtain the detection results.

[0039] In one optional implementation, the detection results of each detection unit in each group are extracted sequentially along the radial direction, including:

[0040] Extract the detection units at each location in the current group sequentially along the radial direction;

[0041] The detection results of each detection unit in the current group are obtained by scanning each detection unit at an odd-numbered interval or at an even-numbered interval.

[0042] This invention can quickly and effectively extract the detection results of each position detection unit by scanning at odd-numbered intervals or based on even-numbered intervals, and quickly obtain the position of the corresponding cooking appliance to be heated.

[0043] Thirdly, the present invention provides a cooking apparatus, comprising: a cooking utensil and a heating cooking stove as described in the first aspect or any corresponding embodiment thereof.

[0044] In one alternative implementation, the cooking appliance is an iron metal appliance or an electromagnetic heating coil appliance.

[0045] This invention uses iron metal utensils or electromagnetic heating coils, which can reduce heat loss during heating and improve heating effect. Attached Figure Description

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] During the use of cooking equipment, when cooking utensils are heated on a flat stovetop, the utensils may vibrate and shift, resulting in reduced heating efficiency and uneven heating of food. This invention provides a heating cooking stove and its control method, as well as the cooking equipment itself. Through a position detection device on the heating cooking stove, the position of the cooking utensils to be heated can be detected in real time, promptly identifying any misalignment. By adjusting the position of the heating unit, the cooking utensils can be aligned with the heating unit, effectively improving the heating effect and increasing heating efficiency.

[0058] This invention provides a heating cooking stove, such as... Figure 1 As shown, it includes:

[0059] Surface 101 is used to receive and heat cooking utensils;

[0060] Heating unit 102 is disposed below receiving surface 101 for heating cooking utensils to be heated;

[0061] The motion mechanism 103 is connected to the heating unit 102 and is used to drive the heating unit to move;

[0062] A position detection device 104 is disposed on the receiving surface 101 and is used to detect the position signal of the cooking appliance to be heated.

[0063] The controller 105 is connected to the position detection device 104 and the motion mechanism 103 respectively. It is used to determine the current position of the cooking appliance to be heated according to the position signal detected by the position detection device 104, and drive the motion mechanism 103 to move the heating unit 102 to the current position to heat the cooking appliance.

[0064] In this embodiment, the receiving surface 101 is a high-strength, impact-resistant ceramic plate or crystal glass, including a microcrystalline plate or a stovetop. The microcrystalline plate is an example of the surface of an induction cooker. The heating unit 102 located below the receiving surface 101 is a high-frequency induction heating coil, i.e., an excitation coil, used to convert high-frequency alternating current into an alternating magnetic field. Passing through a magnetically permeable or ferrous cooking appliance, it generates a large number of dense eddy currents, which are then converted into heat to heat the food inside the appliance, resulting in high energy efficiency. This is only an example and is not intended to limit the application; the specific configuration of the receiving surface 101 and the heating unit 102 can be adapted according to actual application requirements.

[0065] In practical applications, the motion mechanism 103 can control the heating unit 102 to move in both horizontal and vertical directions within a plane. When a misalignment of the cooking appliance to be heated is detected, the motion mechanism 103 adjusts the heating unit 102 to the current position of the cooking appliance and heats it. This allows the heating unit 102 to adapt to the offset of the cooking appliance, track its real-time position, reduce misalignment, and improve heating efficiency. In a specific embodiment, as shown... Figure 2 As shown, by arranging a lead screw in the horizontal direction and a motion mechanism 103 in the vertical direction, the mechanism is connected to the heating unit 102 and controlled to move in the horizontal or vertical direction within a plane.

[0066] In this embodiment, the position detection device 104 includes a plurality of position detection units, each position detection unit being distributed at different positions on the surface of the receiving surface 101. Specifically, by arranging a plurality of position detection units and distributing them at different positions on the surface of the receiving surface 101, it helps to improve the detection accuracy of the position of the cooking appliance to be heated, and further improves the heating efficiency.

[0067] In this embodiment, with the center of the preset standard heating area on the receiving surface 101 as the center, each position detection unit is set along the radial direction outside the preset standard heating area. The preset standard heating area is the area covered by the heating unit 102 in its initial position. Specifically, by setting each position detection unit along the radial direction outside the preset standard heating area, not only can the number of position detection units be reduced, but the calculation of the current position of the cooking appliance to be heated can be accelerated, and the offset state of the cooking appliance to be heated can be obtained quickly, thereby improving heating efficiency. In addition, to a certain extent, it can also avoid interference or heating effects of the heating area on the detection unit, reduce the risk of damage to the detection unit, and ensure the normal operation of the detection unit.

[0068] In this embodiment, the positions of each position detection unit are arranged according to one of the following structures: an annular coordinate system, a rectangular coordinate matrix, or a polar coordinate matrix. Specifically, the position detection units are arranged based on the annular coordinate system, a rectangular coordinate matrix, or a polar coordinate matrix. This arrangement allows for rapid acquisition of the coordinates of the cooking appliance to be heated, and the position calculation process is simple and convenient. A schematic diagram of the position detection unit arrangement based on the above structure is shown below. Figure 3-5 As shown.

[0069] Specifically, Figure 3 This is a schematic diagram of the arrangement of position detection units based on a circular annular angular structure according to an embodiment of the present invention. As shown in the diagram, the position detection units are arranged outside a circle with radius R within a preset standard heating area 301. The detailed arrangement process includes: setting the radius of the preset standard heating area 301 to be R, with a value ranging from 80mm to 220mm, and the arrangement area of ​​the position detection units within a circular annulus from R to R+6cm; dividing the R+1cm circular annulus area into n equal parts according to the radius, it should be noted that the number of parts n is determined by adjusting the diameter of the position detection units, and the specific value is not limited here, but determined according to actual application requirements. After the circular annulus area is equally divided, one position detection unit is arranged in each of the n equally divided areas within the R+1cm circular annulus area; moving outward along the radial direction, for every 1cm increase in radius, the corresponding circular annulus area is again equally divided and the corresponding position detection unit is arranged. It should be noted that the above arrangement of position detection units based on a circular annular angular structure is only an example and is not a limitation, and should be adapted according to actual application requirements.

[0070] Specifically, Figure 4 and Figure 5 These are schematic diagrams of the position detection unit arrangement based on the rectangular coordinate matrix structure and the polar coordinate matrix structure according to embodiments of the present invention. In actual applications, the arrangement of the position detection unit is determined with reference to the above structural diagram. It is divided into a grid within the preset standard heating area 301 circle, which can quickly obtain the current coordinates of the cooking appliance. The coordinates include the offset direction and offset position of the cooking appliance.

[0071] In this embodiment, the spacing between the detection units at each location in the same radial direction decreases as the radius increases. Specifically, the detection units are arranged in a manner where the spacing decreases as the radius increases in the same radial direction. This arrangement can meet the requirements for the number of detection units and detection accuracy both inside and outside the heating area, reducing the overall number of detection units while ensuring the detection accuracy of the central heating area.

[0072] In this embodiment, the position detection unit includes one or more of the following: an electromagnetic induction sensor, a laser sensor, a radar sensor, an infrared sensor, and a radio frequency identification sensor. In a specific embodiment, the position detection unit may employ an electromagnetic induction sensor. The process of detecting the position of the cooking appliance to be heated based on the electromagnetic induction sensor includes: when no cooking appliance is placed on the heating stove, i.e., when no heating operation is being performed on the cooking appliance, the state of the electromagnetic induction sensor remains unchanged, and the state is recorded as 0; when the cooking appliance is placed on the heating stove and heated, electromagnetic induction occurs between the cooking appliance and the heating stove, at which point the electromagnetic induction sensor senses a corresponding current change, and the state changes from 0 to 1. This is merely an example and is not intended to be limiting. The specific type of position detection unit is determined based on the material of the cooking appliance to be heated in the actual application. Using multiple types of position detection units can effectively improve the detection accuracy of the cooking appliance to be heated.

[0073] In this embodiment, the heating unit 102 uses electromagnetic heating. Specifically, electromagnetic heating reduces heat transfer loss during the heating process of the cooking appliance, effectively improving heating efficiency.

[0074] This invention provides a method for controlling a heating cooking stove, which controls the heating cooking stove based on the above or any corresponding embodiment, such as... Figure 6 As shown, the method includes:

[0075] Step S101: Obtain the position signal detected by the position detection device.

[0076] In this embodiment, the position detection device includes: a plurality of position detection units, each of which is distributed at a different position on the surface of the receiving surface.

[0077] Step S102: Determine the current position of the cooking appliance to be heated based on the position signal.

[0078] Step S103: Drive the motion mechanism to move the heating unit to the current position to heat the cooking appliance.

[0079] The heating cooking stove control method of this invention can detect the misalignment of the cooking appliance in real time by detecting the position of the cooking appliance to be heated, and improve the heating effect of the heating cooking stove by adjusting the position of the heating unit. During the heating process, the cooking appliance to be heated and the heating unit are always kept aligned, thereby improving the heating efficiency.

[0080] This invention provides a method for controlling a heating cooking stove, which controls the heating cooking stove based on the above or any corresponding embodiment, such as... Figure 7 As shown, the method includes:

[0081] Step S201: Obtain the position signal detected by the position detection device.

[0082] Specifically, step S201 includes:

[0083] Step S2011: Obtain the detection results of each location detection unit.

[0084] Step S2012: Filter the detection results to identify the target location detection units where there are cooking appliances to be heated.

[0085] Step S2013: Generate a position signal based on the set position corresponding to each target position detection unit in the target position detection unit set.

[0086] In one specific embodiment, if the position detection unit uses an electromagnetic induction sensor, the process of obtaining the position signal of the corresponding cooking appliance to be heated through the position detection unit includes: acquiring all state results of the electromagnetic induction sensor, including states 0 and 1; filtering all detection results belonging to state 1, and determining the position information of the cooking appliance to be heated based on the filtered set of state 1 results, thereby generating a corresponding position signal. The position signal in this embodiment of the invention is generated by detecting the cooking appliance to be heated based on several detection units arranged at different positions on the receiving surface, effectively characterizing the position information of the cooking appliance to be heated.

[0087] In some optional implementations, step S2012 above includes:

[0088] Step a1: Obtain the setting position of each position detection unit.

[0089] Step a2: Using the center of the preset standard heating area on the receiving surface as the center, group the position detection units along the radial direction according to their respective positions.

[0090] Step a3: Extract the detection results of each position detection unit in each group sequentially along the radial direction until the first detection result is obtained as the first position detection unit where a cooking appliance to be heated is present.

[0091] Step a4: Taking the first position detection unit as the center, traverse the detection results of other adjacent position detection units until all the detection results are obtained as position detection units where there is a cooking appliance to be heated, thus forming a target position detection unit set.

[0092] The present invention groups the position detection units and, after determining the first position detection unit of the cooking appliance to be heated, it traverses and filters the detection results of the other adjacent position detection units. This process is simple and convenient, and can quickly obtain the detection results.

[0093] In some alternative implementations, step a3 above includes:

[0094] Step a31: Extract the detection units at each position in the current group sequentially along the radial direction.

[0095] Step a32: Scan each position detection unit in the current group based on odd-numbered sequential intervals or even-numbered sequential intervals to obtain the detection results of each position detection unit.

[0096] Specifically, along the radius R of the heating unit, the annular region is scanned into n equal parts in an odd or even order. For example, if n is 50 parts, only 25 scans are needed, saving half the time per scan. Along the radial direction, a single unit of annular scanning (R+2) is performed at intervals, further reducing the number of scans by half. This allows for the rapid identification of the first target point, followed by sequential scanning of the coordinates adjacent to that point to quickly determine the specific location or area of ​​the cooking appliance to be heated. This invention, through odd-order or even-order interval scanning, can quickly and effectively extract the detection results from each position detection unit, rapidly obtaining the position of the corresponding cooking appliance to be heated.

[0097] Step S202: Based on the position signal, determine the current position of the cooking appliance to be heated. For details, please refer to [link to relevant documentation]. Figure 6 Step S102 of the illustrated embodiment will not be described again here.

[0098] Step S203: Drive the motion mechanism to move the heating unit to the current position to heat the cooking appliance. See details below. Figure 6 Step S203 of the illustrated embodiment will not be described again here.

[0099] This invention provides a cooking device, such as... Figure 8 As shown, it includes: a cooking appliance 801 and a heating cooking stove 802 as described above or in any of its corresponding embodiments.

[0100] In this embodiment, the cooking appliance 801 is either an iron metal appliance or an electromagnetic heating coil appliance. It should be noted that the heating cooking appliance 802 uses electromagnetic heating and can only be used to heat materials with an iron-containing bottom; that is, the cooking appliance 801 must meet the aforementioned material requirements before it can be used for heating. This invention uses an iron metal appliance or an electromagnetic heating coil appliance, so the cooking appliance 801 not only meets the requirements for electromagnetic heating but also reduces heat loss during heating, effectively improving the heating effect.
