Abstract
Description
Technical Field
[0001] This invention relates to a wok rotation setting mode, and more particularly to a wok rotation setting mode in an intelligent cooking machine. Background Technology
[0002] In existing technology, the temperature sensor fixedly installed on the outer wall of the wok of the smart cooking machine measures the temperature of the wok wall by contact. The wok drives the temperature sensor to rotate synchronously by rotating continuously in one direction for several revolutions or rotating alternately in the forward and reverse directions for several revolutions. The signal line of the temperature sensor is usually led out through a conductive slip ring. The shortcomings of this structure are: not only does it require installation space for the conductive slip ring, making installation complicated and increasing production costs, but the conductive slip ring may also experience poor contact due to wear after long-term use. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a wok rotation setting mode in an intelligent cooking machine that allows the temperature sensor to rotate synchronously with the wok several times without the need for components such as conductive slip rings, and can also lead out the signal line.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0005] A wok rotation setting mode is provided for a smart cooking machine, which includes the following:
[0006] 1) Put the ingredients to be cooked into the wok;
[0007] 2) The temperature sensor probe for detecting the temperature of the wok is attached to the outer wall of the wok and rotates synchronously with the wok.
[0008] 3) Start the wok rotation device so that the wok rotates alternately in the forward and reverse directions during the cooking process. The forward and reverse rotation limit angles are defined by the set initial position as the starting point. The signal line of the temperature sensor is allowed to rotate a certain number of times in the forward or reverse direction, corresponding to the cumulative rotation angle.
[0009] Preferably, the angle of the wok's forward or reverse rotation is acquired by a Hall effect sensor and the acquired information is sent to the main control circuit. The main control circuit calculates the actual rotation angle of the wok and compares the actual rotation angle with the forward or reverse limit angle to calculate the remaining rotation angle of the wok to continue forward or reverse rotation without breaking the signal line.
[0010] Preferably, the temperature probe is tightly attached to the outer wall of the wok via a connector. The signal line is divided into a fixed section and a movable section. The fixed section rotates synchronously with the wok, and the upper end of the movable section is connected to the lower end of the fixed section. The remaining part of the movable section is wound around the wok's rotating shaft assembly as the wok rotates.
[0011] Preferably, when the wok rotation device is restarted, the main control circuit can control the wok to rotate in the opposite direction to the current actual rotation angle, so that the wok returns to the initial position.
[0012] Preferably, the initial position is the position of the wok when the moving segment is not entangled. A limit detection device is provided on the frame of the cooking machine corresponding to the initial position. The limit detection device is used to make the wok accurately return to the initial position when the power of the cooking machine is cut off.
[0013] Preferably, if a power outage during the rotation of the wok causes a difference between the actual rotation angle calculated by the main control circuit and the actual rotation angle of the wok, the wok is made to return to its initial position after restarting by taking this difference into account:
[0014] 1) The main control circuit controls the wok to rotate in the opposite direction to the actual rotation angle, corresponding to the rotation angle value.
[0015] 2) After that, control the wok to continue rotating until the limit detection device is triggered.
[0016] Preferably, the angle values of the forward and reverse rotation of the wok are set within 360 degrees.
[0017] The temperature sensor of this invention performs contact temperature measurement on a wok and rotates it synchronously with the wok. By setting forward and reverse rotation limit angles, Hall effect sensors detect the forward or reverse rotation angle of the wok during cooking. After receiving the angle value information, the main control circuit calculates the actual rotation angle and compares it with the forward or reverse rotation limit angle. This ensures that the wok rotates without breaking the signal line of the temperature sensor, guaranteeing the normal and stable operation of the signal line. As a result, there is no need to install components such as conductive slip rings to lead out the signal line, effectively reducing costs and saving installation space. Attached Figure Description
[0018] Figure 1 This is a schematic diagram of the structure of the wok provided by the present invention.
[0019] Figure 2 This invention provides Figure 1 Enlarged diagram of point A in the middle.
[0020] In the diagram: 1. Wok; 2. Temperature sensor; 21. Temperature probe; 22. Signal line. Detailed Implementation
[0021] The wok rotation setting mode in the intelligent cooking machine provided by this invention allows the temperature sensor 2 to rotate synchronously with the wok 1 without the need for a conductive slip ring to lead out the signal line 22 of the temperature sensor 2 (the temperature probe 21 of the temperature sensor 2 is in contact with the wok 1 to measure the temperature). By setting this mode, the cooking machine can work normally and stably without the signal line 22 being torn off as the wok 1 rotates. This effectively reduces production costs, saves installation space, and simplifies the structure.
[0022] The rotating setting mode of the wok 1 includes the following:
[0023] (1) The food feeding part of the cooking machine or the user puts the food to be cooked into the wok 1;
[0024] (2) The temperature probe 21 is attached to the outer wall of the wok 1. During the cooking process of the wok 1, the temperature probe 21 rotates synchronously with the wok 1 and collects the temperature of the wok wall.
[0025] (3) The main control circuit of the cooking machine controls the wok rotation device to drive the wok 1 to rotate forward first and then switch to reverse rotation, or to rotate in reverse first and then switch to forward rotation. During the cooking process, the wok 1 always alternates between forward and reverse rotation. The forward rotation limit angle and reverse rotation limit angle are defined by the initial position set as the starting point of the wok 1 rotation. The signal line 22 is allowed to rotate forward or in reverse for a number of revolutions.
[0026] 1. Temperature sensor 2
[0027] Signal line 22 is divided into fixed section and movable section.
[0028] The fixed section rotates synchronously with the wok 1, and the upper end of the fixed section is connected to the temperature probe 21; the upper end of the movable section is connected to the lower end of the fixed section, and its lower end is electrically connected to the main control circuit. When the wok 1 rotates, the movable section rotates relative to the wok 1 and winds around the circumference of the wok 1 axis. A rotating shaft assembly is provided below the wok 1. The rotating shaft assembly includes a circular shaft coaxial with the wok 1. The movable section winds around the outer circumferential wall of the circular shaft as the wok 1 rotates.
[0029] The temperature probe 21 is attached tightly to the pot wall via a connector, and the connector is preferably one of the following two structures:
[0030] (1) The connector is a spring piece located outside the temperature probe 21. The temperature probe 21 is fixed in the groove on the pot wall by pressing the spring piece towards the pot wall. The fixed section of the signal line 22 extends along the outer wall of the wok 1 to the bottom of the wok 1 and is fixed to the outer wall of the wok 1. The movable section passes through the axial channel located below the wok 1 and is led out.
[0031] (2) Please refer to Figure 1and Figure 2 The connecting component is an arc-shaped plate 3 located outside the wok 1 and rotating synchronously with the wok 1:
[0032] The arc-shaped plate 3 is a strip-shaped structure extending from bottom to top and has elastic properties. The lower part of the arc-shaped plate 3 is fixed to the bottom of the wok 1. The temperature probe 21 is installed on the upper inner side of the arc-shaped plate 3 (inner side: the side facing the wok 1). In the vertical plane passing through the axis of the arc-shaped plate 3 and the wok 1, the curvature center of the arc-shaped plate 3 is set to be on the same side as the curvature center of the outer wall of the wok 1, and the curvature of the arc-shaped plate 3 is greater than the curvature of the outer wall of the wok 1. This ensures that when the wok 1 is placed in the cooking machine, the outer wall of the wok 1 abuts against the temperature probe 21, and the temperature probe 21 is pressed tightly against the wok wall under the action of the rebound force of the arc-shaped plate 3. The fixed section of the signal line 22 extends from the top to the bottom along the inner side of the arc-shaped plate 3 and is fixed to the arc-shaped plate 3. The movable section passes through the axial channel and is led out.
[0033] II. Contents of the rotating setting mode for wok 1 (3):
[0034] 1. The maximum angles for forward rotation and reverse rotation
[0035] The information of the forward rotation limit angle and the reverse rotation limit angle is pre-stored in the main control circuit, and the angle value corresponding to the two is the cumulative rotation angle (also known as the limit angle value).
[0036] The limit angle value is as follows: After determining the length of the active segment of the signal line 22 and the radius of the circular shaft for the active segment to be wound, the initial position is taken as the starting point of the rotation of the wok 1. Under the premise of ensuring that the signal line 22 works stably and does not break, the limit value of the number of rotations that the signal line 22 can rotate forward or backward with the wok 1 is measured, and the angle value is obtained by converting the limit value of the number of rotations.
[0037] The initial position is the position of wok 1 when signal line 22 is not tangled.
[0038] 2. Actual rotation angle
[0039] The actual rotation angle is the cumulative rotation angle value of the position of the wok 1 after a single unidirectional rotation during the cooking process, relative to its initial position.
[0040] The single unidirectional rotation refers to a single action process in which the wok 1 rotates in either the forward or reverse direction from the start to the stop during the cooking process.
[0041] III. The following is one application method of the rotating setting mode of wok 1.
[0042] A Hall effect detection device (such as a Hall sensor built into the wok rotation device) is set up to detect the angle value of a single unidirectional rotation of the wok 1 and send the angle value signal to the main control circuit, which then calculates the corresponding actual rotation angle.
[0043] After the main control circuit calculates the actual rotation angle, it accurately controls the wok 1 to rotate to the initial position as needed. Alternatively, it compares the actual rotation angle with the forward rotation limit angle or the reverse rotation limit angle to calculate the remaining angle value (called the remaining rotation angle) of the wok 1 when it continues to rotate from the current position to the position corresponding to the forward rotation limit angle or the reverse rotation limit angle.
[0044] When the power to the cooking machine is cut off or there is a sudden power outage:
[0045] When power is lost, wok 1 will continue to rotate a certain angle due to inertia (called the power-off angle difference) before stopping. That is, the actual rotation angle corresponding to the position of wok 1 when it stops does not match the actual rotation angle calculated by the main control circuit. Therefore, when the power supply is restored and the wok rotation device is restarted, wok 1 needs to be rotated to the initial position. To ensure that wok 1 is accurately positioned in the initial position, the following method is adopted:
[0046] A limit detection device is installed on the frame of the cooking machine corresponding to the initial position, and a detection plate is correspondingly provided on the wok 1. First, the main control circuit calculates the actual rotation angle when the power is off, and causes the wok 1 to rotate in the opposite direction to the actual rotation angle by the angle value corresponding to the actual rotation angle; then, the wok 1 is controlled to continue rotating until the detection plate triggers the limit detection device.
[0047] The following is a specific application of the rotating setting mode for wok 1:
[0048] Users set the recipe for the dish to be cooked through the operating interface of the cooking machine. The recipe includes the rotation angle corresponding to the alternating forward and reverse rotation of the wok 1 (hereinafter referred to as the rotation parameter of the wok 1). The main control circuit controls the rotation of the wok 1 according to the rotation parameter of the wok 1.
[0049] The parameter values in the rotation parameters of wok 1 are preferably set as follows: the rotation angle value corresponding to the first action is set with the initial position as the reference point, and the rotation angle value corresponding to each subsequent action is set with the position of wok 1 when the previous action is completed as the reference point.
[0050] Install wok 1 in its initial position, start the wok rotation device, and the main control circuit controls the rotation of wok 1 according to the following steps:
[0051] Step 1: The main control circuit compares the rotation angle value of the first action in the rotation parameters of wok 1 with the corresponding forward rotation limit angle or reverse rotation limit angle. When the rotation angle value is within the range of the corresponding limit angle value, the circuit controls wok 1 to execute the first action and rotate accordingly.
[0052] Step 2: When the wok 1 completes the first action, the main control circuit compares the corresponding actual rotation angle with the forward rotation limit angle or the reverse rotation limit angle, calculates the corresponding remaining rotation angle, and judges the rotation angle value corresponding to the second action to determine whether the rotation angle value is within the corresponding remaining rotation angle range.
[0053] Step 3: When the rotation angle value corresponding to the second action in the rotation parameters of wok 1 is within the corresponding remaining rotation angle range, control wok 1 to rotate according to the second action.
[0054] Step 4: When wok 1 completes the second action, the corresponding actual rotation angle is compared with the forward rotation limit angle value or the reverse rotation limit angle value to calculate the corresponding remaining rotation angle. Then, the rotation angle value corresponding to the next action is judged to determine whether the rotation angle value is within the corresponding remaining rotation angle range. If the result is yes, wok 1 is controlled to rotate according to the third action, and so on, until wok 1 completes all actions in the wok 1 rotation parameters.
[0055] The following is another application method provided by this invention:
[0056] In the recipe for the dish to be cooked, set the rotation parameters of wok 1 to rotate alternately in both forward and reverse directions within 360 degrees, and select the extreme angle value greater than 360 degrees.
[0057] The main control circuit controls the wok 1 to rotate according to the set rotation parameters of the wok 1, as described in the above application method.
[0058] To further improve reliability, two limiting blocks are set on the frame of the cooking machine, one of which is an initial limiting block and the other is a forward rotation limiting block or a reverse rotation limiting block (the present invention is a forward rotation limiting block). At the same time, a protrusion is provided at the position corresponding to the initial position of the wok 1.
[0059] The forward rotation limit stop is set at the frame position corresponding to the rotation angle value corresponding to the rotation parameter when the wok 1 rotates forward from the initial position to that angle.
[0060] The reversing limit stop is set at the frame position corresponding to the angle when the wok 1 rotates in the opposite direction from the initial position according to the rotation angle value corresponding to the rotation parameters.
[0061] The initial limit stop is set at the position of the frame when the wok 1 is in the initial position.
[0062] During the cooking process of wok 1, when wok 1 rotates forward or backward until the protrusion touches the forward rotation limit block, the main control circuit controls wok 1 to stop rotating and change direction, and at the same time clears the angle value signal collected by the Hall detection device to zero; after wok 1 changes direction and rotates, when the protrusion touches the initial limit block, the main control circuit controls wok 1 to stop rotating and change direction again, and similarly, clears the angle value signal collected by the Hall detection device to zero, and so on, until wok 1 completes the cooking work.
