[0090] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0091] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0092] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0093] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0094] The specific embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0095] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0096] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the prerequisite for each other's existence.

[0097] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0098] The present disclosure provides a cooking device comprising a pot and a feeding device, the feeding device comprising a seasoning box, a drive unit, a fluid control element, and a feeding adjustment mechanism. The drive unit is configured to pump liquid in the seasoning box into the pot; the fluid control element is disposed between the seasoning box and the drive unit and configured to disconnect or connect the seasoning box and the drive unit; the feeding adjustment mechanism is in communication with the drive unit and configured to, upon detecting liquid flowing through the fluid control element, trigger a count of the number of rotations of the drive unit and control the drive unit to stop when the counted number of rotations reaches a target number of rotations corresponding to a target amount of liquid added.

[0099] The cooking device disclosed herein utilizes a feeding adjustment mechanism to start counting the number of rotations of the driving unit only when it detects that liquid has flowed from the seasoning box into the driving unit, thereby achieving the purpose of precise liquid addition and avoiding errors in the amount of liquid added caused by factors such as delays in opening the fluid control element, which causes the feeding device to start counting the number of rotations when no liquid has flowed into the driving unit.

[0100] Specifically, the liquid adding process of the cooking device of the present disclosure may include:

[0101] Based on the liquid addition instruction, the drive unit is turned on;

[0102] When the driving unit is turned on, the fluid control element connects the seasoning box and the driving unit, and the feeding adjustment mechanism is triggered to detect whether there is liquid flowing when the driving unit is detected to be started;

[0103] After the fluid control element connects the seasoning box and the drive unit, the liquid in the seasoning box begins to flow out of the seasoning box. When the feeding adjustment mechanism detects that the liquid flows through the fluid control element, it triggers the counting of the number of rotations of the drive unit.

[0104] The liquid in the seasoning box continuously flows out of the seasoning box, passes through the fluid control element, and reaches the inlet end of the drive unit's hose. Under the rotation and squeezing action of the pressure roller on the drive unit's pump wheel, the liquid is pumped out from the inlet end of the drive unit's hose into the pot body. During the rotation of the drive unit's pump wheel, the feeding adjustment mechanism continuously counts the number of rotations of the drive unit.

[0105] When the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the volume of liquid extracted by the drive unit reaches the target liquid addition amount. At this time, the feeding adjustment mechanism can control the drive unit to stop and complete the liquid addition work.

[0106] In addition, compared with the prior art in which the volume of liquid drawn by the drive unit is obtained based on the speed and rotation time of the drive unit, the cooking device disclosed herein obtains the volume of liquid drawn by the drive unit based on the number of rotations of the drive unit. Compared with indirect detection based on the working time of the drive unit, this avoids the influence of the unstable speed of the drive unit on the amount of liquid added, thereby further improving the accuracy of liquid addition and making the actual amount of liquid added equal to or close to the target amount of liquid added.

[0107] In one embodiment of the present disclosure, the fluid control element includes a one-way valve, which is configured to connect the seasoning box and the driving unit when the pressure difference between the inlet end of the driving unit and the inside of the seasoning box reaches a preset value, so that the one-way valve can automatically open under the negative pressure provided by the driving unit, without the need to separately control the fluid control element, thereby making the control process of the feeding device simpler.

[0108] In one embodiment of the present disclosure, the feeding adjustment mechanism includes a liquid shortage alarm, which is configured to issue a liquid shortage alarm when it detects that no liquid flows for a continuous period reaching a preset time. This allows the liquid shortage alarm to issue a liquid shortage alarm when there is no liquid in the seasoning box or the target liquid addition amount cannot be met, reminding the user to add liquid to the seasoning box.

[0109] In one embodiment of the present disclosure, the dosing adjustment mechanism further includes a calibration module configured to calibrate the set unit dosing volume of the drive unit. This allows the calibration module to calibrate the set unit dosing volume of the drive unit after the drive unit has been operating for a period of time, thereby ensuring that the set unit dosing volume of the drive unit more closely matches its actual unit dosing volume, thereby reducing errors in dosing accuracy caused by the set unit dosing volume.

[0110] For ease of understanding, refer to Figures 1 to 13 , the specific structure and working principle of the cooking device of the present invention are explained in detail with reference to an embodiment.

[0111] See also Figures 1 to 6 The present disclosure provides a cooking device, comprising a main body 20, a pot body 21 (i.e., a pot) disposed on the main body 20, and a feeding device 10.

[0112] exist Figure 1 In the cooking device shown, a pot body 21 is provided on the main body 20. The pot body 21 is used to hold food and cooperate with other functional components on the main body 20 to cook the food.

[0113] The feeding device 10 of the present disclosure can be used to hold cooking liquids such as seasonings, oil, and water. When cooking in the cooking device, the feeding device 10 delivers cooking liquids such as seasonings, oil, and water into the pot body 21 through its liquid infusion pipe 17, so that the main body 20 can cook the ingredients in the pot body 21.

[0114] The feeding device 10 is communicatively connected to the main unit 20 to enable data transmission between the two. In some application scenarios, the user can manipulate the display area on the main unit 20 to select or set the current operation step, which may include a liquid addition instruction. The main unit 20 transmits the selected liquid addition instruction to the feeding device 10, which then executes the liquid addition operation according to the instruction. This enables automatic liquid addition, improving the automation level of the cooking device.

[0115] Specifically, the feeding device 10 includes a seasoning box 11, a driving unit 131, a fluid control element and a feeding adjustment mechanism.

[0116] The seasoning box 11 is used to contain liquids. Specifically, it can contain any liquid such as liquid mixed seasoning, oil, water, etc., wherein the mixed seasoning includes at least one liquid mixture such as salt, ginger, garlic, light soy sauce, soy sauce, chili, etc.

[0117] The seasoning box 11 is provided with a liquid outlet 111 (please refer to the liquid outlet 111 for details). Figure 3 ),by Figure 3 Taking the direction in FIG. 1 as an example, the liquid outlet 111 is opened at the bottom of the seasoning box 11 so that the liquid seasoning in the seasoning box 11 flows out of the seasoning box 11 under the driving of the driving unit.

[0118] like Figure 7 and Figure 8 As shown, in one embodiment of the present disclosure, at least two seasoning boxes 11 can be provided in the feeding device. Different seasoning boxes 11 can contain different liquids, including liquid mixed seasonings, oil, water, etc. Among them, the liquid mixed seasonings can include at least one of salt water, ginger water, garlic water, light soy sauce, soy sauce, and chili water. Ginger water, garlic water, and chili water are made by grinding solid seasonings such as ginger, garlic, and chili into powder and then adding water. Multiple seasoning boxes 11 can realize the partitioning and placement of multiple seasonings to meet different needs.

[0119] Since some seasonings are used frequently or in larger quantities at one time, while some seasonings are used less frequently or in smaller quantities at one time, the capacities of the seasoning boxes 11 are different.

[0120] According to another embodiment of the present disclosure, only one seasoning box 11 may be provided in the feeding device of the present disclosure, so that the feeding device is dedicated to adding one liquid.

[0121] Furthermore, to facilitate the user's addition of liquid to the seasoning box 11, according to one embodiment of the present disclosure, the seasoning box 11 includes a housing and a lid. The housing can be open, and the lid can be removably sealed to the open opening of the housing. In this way, when the seasoning box 11 is low on seasoning, the user can open the lid and add seasoning to the box, then close the lid again after adding.

[0122] Further, a vent hole can be provided on the cover, the vent hole being communicated with the inside of the seasoning box. Thus, it can be ensured that when the liquid in the seasoning box 11 is extracted, the air pressure inside and outside the seasoning box can be balanced.

[0123] After adding liquid seasoning to the seasoning box 11, when the user cooks, the driving unit pumps the liquid seasoning in the seasoning box 11 into the pot, completing the adding process. That is, the driving unit 131 of the feeding device of the present disclosure is configured to pump the liquid in the seasoning box 11 into the pot.

[0124] In some embodiments of the present application, the drive unit 131 can be implemented as a fluid delivery mechanism such as a peristaltic pump or electromagnetic pump. A peristaltic pump consists of three parts: a drive motor, a pump impeller, and a hose. The drive motor drives the pump impeller, which is equipped with multiple rollers. The drive unit pumps the fluid by alternately squeezing and releasing the hose through the rollers.

[0125] Continue to see Figures 2 to 13 In this embodiment, the feeding device disclosed herein includes a base 13, a drive unit 131 mounted within the base 13, and a buffer chamber 1321 disposed on the base. A fluid control element is disposed between the buffer chamber 1321 and the seasoning box 11, and the fluid control element is configured to connect or disconnect the buffer chamber 1321 and the seasoning box 11. The buffer chamber 1321 and the liquid inlet of the drive unit 131 are connected via a flexible hose, and the liquid outlet of the drive unit 131 is further connected via a flexible hose to a liquid infusion tube 17, which extends through the base 13 to the outside of the base 13 to direct liquid into the pot.

[0126] As previously mentioned, the feeding device of the present disclosure includes multiple seasoning boxes 11 to accommodate different types of seasonings. To simplify the structure, in this embodiment, instead of providing a separate drive unit for each seasoning box 11, several seasoning boxes 11 share a single drive unit 131. The feeding device then adds the liquid in the corresponding seasoning box 11 to the pot according to the recipe configuration.

[0127] For this purpose, see Figure 7In this embodiment, the feeding device of the present disclosure further includes a turntable 12 and a drive motor. The turntable 12 is rotatably mounted on a base 13 and has a plurality of slots for accommodating a plurality of seasoning boxes 11. A communication port is provided at the bottom of the slots, communicating with the liquid outlet 111 of the seasoning box 11. The drive motor is configured to drive the turntable 12 to rotate relative to the base 13 until the liquid outlet 111 of the target seasoning box 11 in the recipe configuration is docked with the buffer chamber 1321 on the base via a fluid control element. When liquid addition is completed, the fluid control element disconnects the liquid outlet of the target seasoning box from the buffer chamber 1321 on the base to prevent liquid leakage.

[0128] Furthermore, in order to prevent dust from the external environment from falling into the turntable 12 and contaminating the liquid, Figure 7 The feeding device of the present disclosure further includes a protective cover 16, which is sleeved on the outer wall of the turntable 12 and rotates with the turntable.

[0129] Similarly, for dust protection considerations, continue to refer to Figure 7 In this embodiment, the feeding device disclosed herein is further provided with an upper cover 15 , which is configured to cover the seasoning box 11 and dock with the protective cover 16 .

[0130] See also Figure 8 and Figure 9 In this embodiment, the fluid control element disclosed herein is a one-way valve 14, which is disposed at the liquid outlet 111 of the seasoning box and is opened only when liquid needs to be added and closed when liquid does not need to be added.

[0131] According to one embodiment of the present disclosure, the one-way valve 14 of the present disclosure is configured to connect the seasoning box 11 and the driving unit 131 when the pressure difference between the inlet end of the driving unit 131 and the inside of the seasoning box 11 reaches a preset value.

[0132] Specifically, the one-way valve 14 includes a valve body 141 , a plunger 142 and a spring 143 . The valve body 141 is sealed and fixed to the box body, and the spring 143 is connected to the plunger 142 and the valve body 141 respectively.

[0133] When the one-way valve 14 is in a stationary state, the plunger 142 of the one-way valve 14 is in a sealed closed position relative to the valve body 141, thereby disconnecting the seasoning box 11 and the driving unit 131; under the action of the suction force (the negative pressure provided by the driving unit 131), the plunger 142 of the one-way valve 14 moves to an open position relative to the valve body 141, thereby connecting the seasoning box 11 and the driving unit 131.

[0134] After the plunger 142 is no longer affected by the suction force, the spring 143 resets the plunger 142 and lifts it up. The plunger 142 is again in the sealed closed position relative to the valve body 141 , thereby disconnecting the seasoning box 11 and the driving unit 131 .

[0135] It should be noted that, based on meeting the assembly process and functional requirements, the fluid control element only needs to be disposed between the seasoning box 11 and the drive unit 131 and be able to disconnect or connect the seasoning box 11 and the drive unit 131. The fluid control element disclosed herein may be an electromagnetic one-way valve.

[0136] As described in the background, existing dosing devices use the drive unit's rotational speed and rotation time to determine the volume of liquid pumped by the drive unit. Dosing stops when the liquid volume reaches the target dosage. However, due to the drive unit's structural characteristics, its rotational speed cannot be guaranteed to be continuously stable, which can easily lead to inaccurate dosing. Furthermore, fluid control components such as the one-way valve 14 may experience delays in opening, resulting in a discrepancy between the liquid volume measured by the dosing device and the actual volume of liquid pumped, further contributing to inaccurate dosing.

[0137] To this end, the feeding device 10 of the present disclosure is also provided with a feeding adjustment mechanism, which is communicated with the driving unit 131 and is configured to trigger the counting of the number of rotations of the driving unit 131 when liquid is detected flowing through the fluid control element, and control the driving unit 131 to stop when the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount.

[0138] in, Figure 1 The reference numeral 10 represents only the hardware portion of the feeding device 10. The software portion of the feeding device 10 may be arranged together with the hardware portion of the feeding device 10, or may be arranged on the main body 20, or may be part of the electronic processing system of the entire cooking device.

[0139] The feeding adjustment mechanism is used to adjust the amount of liquid added by the drive unit 131. Specifically, when the feeding adjustment mechanism detects liquid flowing through the fluid control element, it triggers the counting of the number of rotations of the drive unit 131. When the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the drive unit 131 is controlled to stop and stop adding liquid. The number of rotations refers to the number of rotations of the rotating shaft of the drive unit 131. Since the rotating shaft drives the pump impeller under the drive of a motor or other driving mechanism, the number of rotations of the rotating shaft is also the number of rotations of the pump impeller.

[0140] Since it is difficult to ensure a stable rotation speed of the driving unit 131 when a general motor controls the driving unit 131 , a large error may occur when the rotation speed and rotation time are used to obtain the volume of liquid pumped out by the driving unit 131 as described above.

[0141] However, the feeding adjustment mechanism of the present disclosure utilizes the number of rotations of the counting driving unit 131 to control the driving unit 131 to stop feeding only after the target number of rotations reaches the target feeding amount.

[0142] Since the volume of liquid brought out by the driving unit 131 when it rotates one circle is basically unchanged, the method of obtaining the target liquid addition amount by counting the number of rotations is not affected by the stability of the speed of the driving unit 131, thereby ensuring that the actual liquid addition amount is close to or equal to the target liquid addition amount, thereby achieving the purpose of precise liquid addition.

[0143] As mentioned above, the one-way valve 14 is opened under the negative pressure provided by the drive unit 131, and it takes a certain amount of time for the drive unit 131 to provide negative pressure. Therefore, there is a time difference between the opening of the one-way valve 14 and the start-up of the drive unit. During this time difference, no liquid actually enters the drive unit 131. However, since the number of rotations of the drive unit 131 has begun to be counted, the obtained liquid volume does not match the actual liquid volume extracted, resulting in the problem that the actual liquid addition amount does not reach the target liquid addition amount.

[0144] That is, if the number of rotations of the driving unit 131 within the time required for opening the fluid control element is also counted in the counted number of rotations, an error will occur, thereby affecting the liquid addition accuracy.

[0145] Therefore, the feeding adjustment mechanism of the present invention triggers the counting of the number of rotations of the driving unit 131 only when it detects that liquid flows through the fluid control element, avoiding the opening time of the fluid control element from affecting the feeding process, thereby improving the feeding accuracy.

[0146] The liquid adding process of the feeding device of the present disclosure may include:

[0147] Based on the liquid adding instruction, the driving unit 131 is turned on;

[0148] When the driving unit 131 is turned on, the fluid control element connects the seasoning box 11 and the driving unit 131, and the feeding adjustment mechanism is triggered to detect whether there is liquid flowing when the driving unit 131 is detected to be started;

[0149] After the fluid control element connects the seasoning box 11 and the driving unit 131, the liquid in the seasoning box 11 begins to flow out of the seasoning box 11. When the feeding adjustment mechanism detects that the liquid flows through the fluid control element, it triggers the counting of the number of rotations of the driving unit 131.

[0150] The liquid in the seasoning box 11 continuously flows out of the seasoning box 11, passes through the fluid control element, and reaches the inlet end of the hose of the drive unit 131. Then, under the rotation and squeezing action of the pressure roller on the pump wheel of the drive unit 131, the liquid is pumped out from the inlet end of the hose of the drive unit 131 into the pot body. During the rotation of the pump wheel of the drive unit 131, the feeding adjustment mechanism continuously counts the number of rotations of the drive unit 131.

[0151] When the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the volume of liquid extracted by the driving unit 131 reaches the target liquid addition amount. At this time, the feeding adjustment mechanism can control the driving unit 131 to stop and complete the liquid addition work.

[0152] To prevent mixing of different liquids, the fluid control element can be turned off when the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount. The drive unit is then controlled to operate until all liquid in the pipeline from the fluid control element to the pot body is emptied into the pot body. This way, when other liquids are added, the liquid in the pipeline from the fluid control element to the pot body will not contain the previously added liquid, ensuring that the different liquids do not mix and preventing contamination between the different liquids. Although the feeding device adds some liquid, the amount of this liquid is relatively small and will not affect the cooking process of the cooking device.

[0153] It should be noted that the number of rotations of the drive unit is not limited to an integer; it can also be a fraction. As mentioned above, the pump wheel of drive unit 131 is equipped with multiple pressure rollers. During the rotation of the pump wheel, each pressure roller squeezes the hose once, and drive unit 131 extracts liquid once. Therefore, during one rotation of the pump wheel, the number of liquid extractions by drive unit 131 is equal to the number of pressure rollers. Therefore, when the number of pressure rollers is n, the minimum unit of rotation is 1 / n.

[0154] Based on this, when calculating the target number of rotations corresponding to the target liquid addition amount, if the result of dividing the target liquid addition amount by the set unit liquid addition volume of the drive unit 131 is an integer multiple of 1 / n rotations, this result can be directly used as the target number of rotations.

[0155] If the result of dividing the target liquid addition amount by the set unit liquid addition volume of the driving unit 131 is not an integer multiple of 1 / n revolution, the integer multiple of 1 / n revolution with the smallest difference can be used as the target number of rotations.

[0156] To facilitate understanding, let's use an example: For example, if the target liquid dosage is 50ml, the unit liquid dosage volume set for drive unit 131 is 0.065ml, the number of rollers in drive unit 131 is 3, and the minimum unit of rotation is 1 / 3 of a revolution. In this case, the target liquid dosage of 50ml divided by the unit liquid dosage volume set for drive unit 131, 0.065ml, yields 769.23 revolutions, which is not an integer multiple of 1 / 3 of a revolution. Therefore, the target number of revolutions can be set to 769 + 1 / 3 revolutions, which is an integer multiple of 1 / n revolutions that minimizes the difference between 769.23 revolutions and 769.23 revolutions.

[0157] According to one embodiment of the present disclosure, the feeding adjustment mechanism of the present disclosure includes a rotation detection element, a liquid detection element and a control unit.

[0158] The rotation detection element is configured to detect the number of rotations of the driving unit 131 .

[0159] According to one embodiment of the present disclosure, the rotation detection element is a grating code disk disposed on the shaft of the drive unit 131. Each time the shaft of the drive unit 131 rotates a certain angle, the grating code disk receives a fixed pulse, allowing the control unit to determine the number of rotations of the drive unit 131 based on the rotation angle of the shaft.

[0160] Based on the structure of the drive unit, when the number of pressure rollers is n, the minimum unit of the number of rotations is 1 / n circle. Therefore, the grating code disk can be set so that the shaft of the drive unit 131 receives a fixed pulse every time it rotates 360 / n°, so that the minimum unit of the number of rotations of the drive unit 131 obtained by the control unit and the above-mentioned target number of rotations are both 1 / n circle.

[0161] According to another embodiment of the present disclosure, the rotation detection element of the present disclosure includes at least one magnetic member and a Hall sensor, the magnetic member is arranged on the rotating shaft of the driving unit, and the Hall sensor is arranged on the housing of the driving unit. The magnetic member is configured to generate a periodically changing magnetic field at the Hall sensor under the drive of the rotating shaft, and the Hall sensor is configured to obtain the number of rotations of the driving unit based on the measured number of magnetic change cycles.

[0162] Specifically, since the magnetic part will generate a periodically changing magnetic field at the Hall sensor under the drive of the rotating shaft, the magnetic field strength value of the magnetic part at each angle can be obtained in advance. Then, during actual detection, the Hall sensor obtains the rotation angle of the magnetic part based on the fluctuation curve of the magnetic field strength change, and then obtains the number of rotations of the drive unit.

[0163] During one rotation cycle of the magnetic part, the curve of the change in magnetic field strength detected by the Hall sensor must have a maximum or minimum value of the magnetic field. Therefore, the number of measured maximum or minimum values ​​can also be used as the number of rotations of the drive unit. At this time, the minimum unit of the number of rotations obtained is 1 circle.

[0164] The liquid detection element is disposed between the fluid control element and the driving unit 131 and is configured to detect whether liquid is flowing.

[0165] According to one embodiment of the present disclosure, the liquid detection element of the present disclosure can be a photoelectric sensor 133 arranged at the buffer cavity 1321. The photoelectric sensor 133 includes a transmitting end and a receiving end. The transmitting end is configured to send a light signal to the receiving end. The optical path of the light signal runs through the pipeline between the fluid control element and the driving unit 131. The receiving end is configured to determine whether liquid is flowing when receiving the light signal.

[0166] Specifically, the optical signal sent by the transmitting end passes through the buffer cavity 1321 and reaches the receiving end. However, the receiving end cannot receive the optical signal when liquid is flowing through it. Therefore, if no optical signal is received, it can be determined that liquid is flowing; if an optical signal is received, it can be determined that no liquid is flowing. Of course, to facilitate the optical signal to pass through the buffer cavity 1321, the area on the wall of the buffer cavity 1321 where the optical signal passes can be made transparent.

[0167] According to another embodiment of the present disclosure, the liquid detection element of the present disclosure is a pressure sensor disposed on the pipe wall of the pipe between the fluid control element and the driving unit 131 .

[0168] If liquid flows through the pipe between the fluid control element and the drive unit 131, the pressure sensor will detect the liquid pressure. If liquid flows through the pipe between the fluid control element and the drive unit 131, the pressure sensor will not detect the liquid pressure. Therefore, the pressure sensor can determine whether liquid is flowing based on whether it receives liquid pressure.

[0169] The control unit is communicatively connected to the rotation detection element, the liquid detection element, and the drive unit 131. The communication connection can be a wired connection, including at least one of an electrical connection and an electrical signal connection, or a wireless connection via Bluetooth, WiFi, or the like, as long as the functional elements can communicate with each other.

[0170] The control unit is configured to trigger the rotation detection element to count the number of rotations of the drive unit 131 when the liquid detection element detects liquid flowing through, and control the drive unit 131 to stop when the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount.

[0171] Specifically, during the liquid addition process, the control unit detects whether the driving unit 131 is turned on. When it is detected that the driving unit 131 is turned on, the liquid detection element is triggered to detect whether liquid is flowing;

[0172] When the liquid detection element detects whether liquid is flowing, it continuously sends a detection signal to the control unit to indicate whether liquid is flowing.

[0173] After the control unit receives a detection signal from the liquid detection element indicating that liquid has flowed, the control unit triggers the rotation detection element to count the number of rotations of the driving unit 131;

[0174] During the process of counting the number of rotations of the driving unit 131, the rotation detection element continuously sends the counted number of rotations to the control unit;

[0175] When the number of rotations counted by the control unit reaches the target number of rotations corresponding to the target liquid addition amount, the driving unit 131 is controlled to stop, and the liquid addition is completed.

[0176] It should be noted that, in one embodiment of the present disclosure, before the control unit detects whether the drive unit 131 is turned on, the control unit can also obtain the target number of rotations of the drive unit 131 based on the target liquid addition amount and the unit liquid addition volume of the drive unit 131. The specific calculation method has been described in detail in the previous article and will not be repeated here.

[0177] It is understandable that when the amount of liquid in the seasoning box is insufficient, the feeding device may suffer from a lack of liquid during operation.

[0178] To this end, according to one embodiment of the present disclosure, the feeding and regulating mechanism of the present disclosure also includes a liquid shortage alarm, which is communicatively connected to the liquid detection element and is configured to issue a liquid shortage alarm when the liquid detection element detects that no liquid flows for a continuous period reaching a preset time.

[0179] It should be noted that the preset duration can be a specific value or a range of values. The preset duration is set to take into account factors such as the presence of bubbles in the liquid or the delay in opening the fluid control element, so as to avoid frequent alarms of the feeding device that affect the user experience.

[0180] During the operation of the feeding device, the liquid detection element will continuously send a detection signal to the liquid shortage alarm whether there is liquid flowing.

[0181] When there is no liquid in the seasoning box 11, the detection signals of the liquid detection element are all signals indicating that there is no liquid flowing. As mentioned above, during the normal liquid addition process, since it takes some time for the pipeline control element to open, the liquid detection element will also detect that there is no liquid flowing for a period of time, but this time will not be too long. Therefore, when the duration of no liquid flowing reaches the preset time, it can be considered that there is no liquid in the seasoning box 11.

[0182] Therefore, the liquid shortage alarm can obtain the duration of no liquid flow based on the detection signal of no liquid flow. When the duration of no liquid flow reaches a preset duration, it can be considered that there is no liquid in the seasoning box 11, and a liquid shortage alarm is issued to remind the user to add liquid to the seasoning box 11.

[0183] When the liquid in the seasoning box 11 cannot meet the target liquid addition amount, the driving unit 131 will first extract the liquid in the seasoning box 11; after the liquid in the seasoning box 11 is completely extracted, the liquid detection element will detect a detection signal of continuous no liquid flowing.

[0184] When the airtightness of the feeding device 10 is relatively poor, bubbles may be mixed into the liquid. When bubbles are mixed into the liquid, the liquid detection element may also detect a signal that no liquid is flowing. However, when bubbles are mixed into the liquid, the duration of the signal that no liquid is flowing is generally short, which is significantly different from the duration of no liquid flowing when the liquid in the seasoning box 11 does not meet the target liquid addition amount.

[0185] At this time, the liquid shortage alarm can also obtain the duration of no liquid flow based on the detection signal of no liquid flow. If the duration of no liquid flow does not reach the preset time, when the signal of liquid flow is detected, it can be determined that bubbles have been mixed with the liquid, and the liquid shortage alarm will not issue a liquid shortage alarm.

[0186] When the duration without liquid flow reaches a preset duration, it can be considered that the liquid in the seasoning box 11 has been pumped out, and the liquid shortage alarm will sound a liquid shortage alarm to remind the user to add liquid to the seasoning box 11.

[0187] Specifically, there are two types of liquid shortage situations. One is that there is no liquid in the seasoning box 11 when the feeding device starts working. The other is that after the feeding device starts adding liquid and the driving unit 131 draws away all the liquid in the seasoning box 11, the seasoning box 11 becomes liquid-deficient.

[0188] The preset durations in these two cases may be the same or different.

[0189] According to one embodiment of the present disclosure, the feeding device of the present disclosure sets the preset time length when there is no liquid in the seasoning box 11 to 3 seconds when the feeding device starts working. That is, after the driving unit 131 is started, if no liquid flows out within 3 seconds, it is determined that there is no liquid in the seasoning box 11.

[0190] In another embodiment of the present disclosure, after the feeding device starts to feed, and the driving unit 131 draws out all the liquid in the seasoning box 11, the preset time for the seasoning box 11 to be short of liquid is set to 1 second, that is, after the driving unit 131 starts pumping liquid, if no liquid flows out for 1 second, it is determined that the liquid in the seasoning box 11 has been pumped out.

[0191] Specifically, the liquid shortage alarm can provide a liquid shortage alarm by emitting a sound signal, a light signal, or the like.

[0192] When the liquid shortage alarm sends out a liquid shortage alarm signal, the control unit can also control the driving unit 131 to stop so as to suspend the liquid addition.

[0193] When the liquid in the seasoning box 11 cannot meet the target liquid addition amount, the driving unit 131 will pump liquid for a period of time. Since this part of the liquid has been pumped into the pot body, in order to prevent repeated liquid addition, when the liquid shortage alarm sounds a liquid shortage alarm, the control unit needs to save the currently counted number of rotations.

[0194] When the user adds liquid and the driving unit 131 is restarted, the control unit may use the previously saved counted number of rotations as the initial value of the counted number of rotations, thereby avoiding repeated addition of liquid.

[0195] Since the currently counted number of rotations includes the number of rotations during the duration when no liquid flows, the counted number of rotations does not match the actual amount of liquid extracted.

[0196] To this end, according to one embodiment of the present disclosure, when the liquid shortage alarm of the feeding device of the present disclosure sends a liquid shortage alarm signal, the control unit subtracts the number of rotations during the continuous period without liquid flow from the currently counted number of rotations and saves it as the counted number of rotations, so that the counting can be continued on the same basis after the liquid addition is completed and the driving unit is restarted, thereby further improving the accuracy of the liquid addition amount.

[0197] As previously mentioned, the volume of liquid pumped out per rotation of the drive unit 131 remains essentially constant. However, over time, the power of the drive unit 131's motor decreases, and the friction of the drive unit 131's hose increases. These factors can cause the actual unit liquid filling volume of the drive unit 131 to decrease. In other words, the currently set unit liquid filling volume of the drive unit 131 may not match its actual unit liquid filling volume. Consequently, even if the drive unit has reached the target number of rotations, the actual amount of liquid pumped out may not reach the target liquid filling volume, which can also affect the liquid filling accuracy of the dosing device.

[0198] To this end, according to one embodiment of the present disclosure, the feeding adjustment mechanism of the present disclosure also includes a calibration module, which is configured to calibrate the set unit liquid filling volume of the drive unit 131 so as to make it infinitely close to or even equal to the current actual unit liquid filling volume of the drive unit, thereby ensuring that the actual liquid filling amount obtained after the drive unit rotates the target number of revolutions is infinitely close to or even equal to the target liquid filling amount, so as to improve the liquid filling accuracy of the hydraulic equipment.

[0199] According to one embodiment of the present disclosure, the calibration module includes a duration recording element and a first calibration unit. The duration recording element is configured to record the total operating hours of the drive unit 131. The first calibration unit is communicatively connected to the duration recording element and is configured to correct a set unit liquid filling volume for the drive unit based on the life decay curve of the drive unit and the total operating hours of the drive unit.

[0200] Because the lifespan decay of the same type of drive unit is essentially the same, the unit liquid addition volume can be calibrated based on the lifespan decay curve of that drive unit. The method for obtaining the lifespan decay curve of this type of drive unit can include obtaining the unit liquid addition volume of multiple identical drive units at different total operating hours, and fitting a scatter plot between the total operating hours and the unit liquid addition volume of the multiple identical drive units to obtain the lifespan decay curve. The total operating hours are the sum of the operating hours of the drive unit during all liquid addition processes since it was first put into use.

[0201] It should be noted that there are many forms of life decay curves.

[0202] According to one embodiment of the present disclosure, the life decay curve of the drive unit of the present disclosure is a curve in which the unit liquid volume decays with the square of the total working time. For details, see formula (1):

[0203] v=kt 2 +b formula (1)

[0204] Where v is the unit liquid addition volume, k is the correlation coefficient between the unit liquid addition volume and the total working time, t is the total working time, and b is the volume constant.

[0205] The life decay curve is set in the form of a curve in which the unit liquid volume decays with the square of the total working time, which can better conform to the actual life decay of the driving unit 131, and the calibration result has high accuracy.

[0206] According to another embodiment of the present disclosure, the calibration module of the present disclosure includes a mass measurement element and a second calibration unit.

[0207] The mass measuring element is configured to measure the mass of the liquid drawn out when the driving unit 131 rotates a set number of times.

[0208] The mass measuring element can be a weighing element such as an electronic scale. The pot is placed on the mass measuring element and weighed. The weight of the pot itself and the material currently contained in the pot is subtracted from the weighing result to obtain the weight of the liquid extracted by the drive unit.

[0209] The second calibration unit is in communication with the mass measuring element and is configured to correct the set unit liquid filling volume of the driving unit 131 based on the mass of the liquid extracted by the driving unit 131 when the driving unit 131 rotates a set number of times and the density of the liquid measured by the mass measuring element.

[0210] Specifically, when calibrating the set unit liquid addition volume of the driving unit 131, first add a sufficient amount of liquid with a known density to the seasoning box 11, and then use the above-mentioned rotation detection element, liquid detection element and control unit to control the driving unit 131 to rotate a set number of circles.

[0211] The specific method of controlling the driving unit 131 to rotate a set number of times using the above-mentioned rotation detection element, liquid detection element and control unit is that when the control unit detects that the driving unit 131 is started, it triggers the liquid detection element to detect whether liquid is flowing through. When the liquid detection element detects that liquid is flowing through, the control unit triggers the rotation detection element to count the number of rotations of the driving unit 131. When the counted number of rotations reaches the set number of rotations, the driving unit 131 is controlled to stop.

[0212] After the driving unit 131 is controlled to rotate a set number of times, the mass of the liquid pumped out by the driving unit 131 rotating the set number of times can be measured by the mass measuring element.

[0213] The cooking device obtains the current unit liquid volume of the driving unit according to formula (2):

[0214]

[0215] Where V is the current unit liquid filling volume of drive unit 131, m is the mass of liquid pumped out by drive unit 131 after a set number of rotations, as measured by the mass measuring element, ρ is the density of the liquid, and T is the set number of rotations. Finally, the set unit liquid filling volume of drive unit 131 is corrected to the current unit liquid filling volume.

[0216] Since the above process obtains the current unit liquid filling volume of the currently used driving unit 131 and is not affected by the error caused by the individual structural differences of the driving unit, the obtained calibration result can better fit the actual working condition of the driving unit 131 itself.

[0217] The present disclosure also provides another feeding device, which includes a seasoning box, a driving unit and a feeding adjustment mechanism.

[0218] The seasoning box is used to hold liquid. The drive unit is used to pump the liquid in the seasoning box into the pot. The feeding adjustment mechanism is used to adjust the amount of liquid added by the drive unit. Specifically, when the drive unit is detected to be activated, the number of rotations of the drive unit is triggered to be counted. When the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the drive unit is controlled to stop.

[0219] Compared with the prior art which uses the rotation speed and rotation time of the driving unit to obtain the volume of liquid drawn out by the driving unit, the feeding device disclosed in the present invention obtains the volume of liquid drawn out by the driving unit based on the number of rotations of the driving unit. Compared with indirect detection based on the working time of the driving unit, it avoids the influence of the unstable rotation speed of the driving unit on the amount of liquid added, thereby improving the accuracy of liquid addition and making the actual amount of liquid added equal to or close to the target amount of liquid added.

[0220] According to one embodiment of the present disclosure, the feeding adjustment mechanism of the present disclosure includes a rotation detection element and a control unit. The rotation detection element is configured to detect the number of rotations of the driving unit. The control unit is in communication with the rotation detection element and is configured to trigger the rotation detection element to count the number of rotations of the driving unit when it detects that the driving unit is started. When the number of rotations counted by the rotation detection element reaches the target number of rotations corresponding to the target liquid addition amount, the driving unit is controlled to stop. The specific implementation of the rotation detection element and the control unit is the same as the corresponding elements in the previous feeding device mentioned above. Those skilled in the art can fully implement it based on the above description, and will not be repeated here.

[0221] The present disclosure also provides a feeding control method, which is applied to a feeding device comprising a seasoning box, a drive unit, a fluid control element, and a feeding adjustment mechanism. The drive unit is configured to pump liquid in the seasoning box into a pot body, the fluid control element is disposed between the seasoning box and the drive unit and is configured to disconnect or connect the seasoning box and the drive unit, and the feeding adjustment mechanism is in communication with the drive unit.

[0222] It should be noted that the specific structures and working principles of the seasoning box, drive unit, fluid control element and feeding adjustment mechanism are the same as those described above. Those skilled in the art can fully implement them based on the above description. In order to keep the text concise, they will not be repeated here.

[0223] The feeding control method disclosed herein comprises the following main steps:

[0224] The feeding regulating mechanism triggers counting of the number of rotations of the driving unit when detecting that liquid flows through the fluid control element;

[0225] When the number of rotations counted by the feeding regulating mechanism reaches the target number of rotations corresponding to the target liquid feeding amount, the driving unit is controlled to stop.

[0226] For ease of understanding, refer to Figure 14 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0227] In this embodiment, the feeding control method includes the following steps:

[0228] S101: Determine whether the feeding adjustment mechanism detects that the driving unit is started. If so, execute step S102; otherwise, return to continue executing step S101.

[0229] Since liquid will flow out of the fluid control element only after the driving unit is turned on, the feeding adjustment mechanism can be triggered to detect whether liquid flows only when it detects that the driving unit is started.

[0230] S102: The feeding adjustment mechanism is triggered to detect whether liquid flows through the fluid control element.

[0231] When the driving unit is detected to be started, the feeding regulating mechanism starts to detect whether liquid flows through the fluid control element. Specifically, a liquid detection element such as the above-mentioned photoelectric sensor can be selected to detect whether liquid flows through the fluid control element.

[0232] S103: Determine whether the feeding adjustment mechanism detects that liquid flows through the fluid control element. If so, execute step S104; otherwise, return to execute step S103.

[0233] As described above, in order to ensure that the counted number of rotations does not include the number of rotations of the drive unit during the opening time of the fluid control element, the feeding adjustment mechanism can trigger the counting of the number of rotations of the drive unit when it detects that liquid flows through the fluid control element.

[0234] S104: The feeding adjustment mechanism triggers the counting of the number of rotations of the driving unit.

[0235] When liquid is detected flowing through the fluid control element, the feeding adjustment mechanism starts counting the number of rotations of the driving unit. Specifically, the rotation detection element such as the grating code disk can be used to count the number of rotations of the driving unit.

[0236] S105: Determine whether the number of rotations detected by the feeding adjustment mechanism reaches the target number of rotations corresponding to the target liquid feeding amount. If yes, execute step S106; otherwise, return to execute step S105.

[0237] S106: The feeding adjustment mechanism controls the driving unit to stop.

[0238] When the counted number of rotations does not reach the target number of rotations corresponding to the target liquid addition amount, the volume of liquid pumped out by the driving unit has not yet reached the target liquid addition amount, so the driving unit needs to continue adding liquid.

[0239] When the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the volume of liquid extracted by the drive unit can be considered to be the target liquid addition amount. At this time, the drive unit can be controlled to stop and the liquid addition work is completed.

[0240] It can be seen that in the feeding control method disclosed in the present invention, the feeding adjustment mechanism starts counting the number of rotations of the driving unit only when it detects that liquid flows into the driving unit from the seasoning box, thereby achieving the purpose of precise liquid addition and avoiding the error in the amount of liquid added caused by the feeding device starting to count the number of rotations when no liquid flows into the driving unit due to factors such as the delay in opening the fluid control element.

[0241] Furthermore, compared to the prior art method of using the drive unit's rotational speed and rotation time to determine the volume of liquid pumped by the drive unit, the disclosed method of controlling the liquid pumping volume based on the number of rotations of the drive unit is used. This indirectly detects the volume of liquid pumped by the drive unit based on the operating time of the drive unit, thereby avoiding the impact of unstable drive unit rotational speed on the amount of liquid pumped, thereby further improving the accuracy of liquid pumping and ensuring that the actual amount of liquid pumped is equal to or close to the target amount of liquid pumped. Of course, the target number of rotations corresponding to the target amount of liquid pumped can be pre-stored in the pumping control mechanism or calculated.

[0242] According to one embodiment of the present disclosure, in the feeding control method, when the feeding adjustment mechanism detects liquid flowing through, before triggering the counting of the number of rotations of the driving unit, the method further includes:

[0243] The feeding adjustment mechanism calculates the target number of rotations that the driving unit of the feeding device needs to rotate according to the target liquid feeding amount and the set unit liquid feeding volume of the driving unit.

[0244] For ease of understanding, refer to Figure 15 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0245] In this embodiment, the feeding control method includes the following steps:

[0246] S201: The feeding adjustment mechanism calculates the target number of rotations that the driving unit of the feeding device needs to rotate according to the target liquid feeding amount and the set unit liquid feeding volume of the driving unit.

[0247] The method for calculating the target number of rotations is described above. Steps S202 to S207 refer to the above-mentioned steps S101 to S106 and are not described in detail here.

[0248] Since the seasoning box may be short of liquid during the execution of the feeding control method, a liquid shortage alarm needs to be issued to remind the user to add liquid to the seasoning box.

[0249] According to one embodiment of the present disclosure, in the feeding control method, when the feeding adjustment mechanism detects that liquid flows through the fluid control element, before triggering the counting of the number of rotations of the driving unit, the method further includes:

[0250] When the feeding regulating mechanism detects that the driving unit is started, it triggers to detect whether there is liquid flowing;

[0251] When the feeding regulating mechanism detects that the driving unit is started, the triggering detection of whether liquid flows through further includes:

[0252] When the duration of no liquid flow reaches a preset value, the feeding regulating mechanism will issue a liquid shortage alarm.

[0253] Before the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the feeding adjustment mechanism further includes:

[0254] When the duration of no liquid flow detected by the feeding regulating mechanism reaches a preset value, the feeding regulating mechanism controls the driving unit to stop and subtracts the number of rotations within the duration of no liquid flow from the counted number of rotations.

[0255] For ease of understanding, refer to Figure 16 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0256] In this embodiment, the feeding control method includes the following steps:

[0257] S301: Determine whether the feeding adjustment mechanism detects that the driving unit is started. If so, execute step S302; otherwise, return to continue executing step S101.

[0258] S302: The feeding regulating mechanism is triggered to detect whether there is liquid flowing.

[0259] Steps S301 and S302 may refer to steps S101 and S102.

[0260] S303: Determine whether the feeding adjustment mechanism detects that liquid flows through the fluid control element. If so, execute step S306; otherwise, execute step S304.

[0261] As described above, in order to ensure that the counted number of rotations does not include the number of rotations of the drive unit during the opening time of the fluid control element, the feeding adjustment mechanism can trigger the counting of the number of rotations of the drive unit when it detects that liquid flows through the fluid control element.

[0262] S304: Determine whether the duration of no liquid flow detected by the feeding regulating mechanism has reached a preset value. If so, execute step S305; otherwise, return to execute step S304.

[0263] S305: The feeding regulating mechanism issues a liquid shortage alarm and controls the driving unit to shut down.

[0264] As described above, when the dosing device begins operation and the seasoning box is completely empty of liquid, the dosing adjustment mechanism will continuously detect that no liquid is flowing through the fluid control element. During normal dosing, since the pipeline control element takes some time to open, the dosing adjustment mechanism will also detect that no liquid is flowing for a period of time. However, this period of time will not be too long. Therefore, when the period of no liquid flow reaches a predetermined time, it can be determined that there is no liquid in the seasoning box.

[0265] Therefore, the feeding adjustment mechanism needs to obtain the duration of no liquid flow based on the detection signal of no liquid flow. When the duration of no liquid flow reaches the preset duration, it can be considered that there is no liquid in the seasoning box at all, and a liquid shortage alarm is issued to remind the user to add liquid to the seasoning box.

[0266] After the feeding adjustment mechanism issues a liquid shortage alarm and controls the driving unit to stop, the feeding adjustment mechanism can continue to detect whether the driving unit is started. After detecting that the driving unit is started, the feeding control method described above is continued to be executed to re-add liquid.

[0267] S306: The feeding adjustment mechanism triggers the counting of the number of rotations of the driving unit.

[0268] When it is detected that liquid flows through the fluid control element, the feeding adjustment mechanism starts counting the number of rotations of the driving unit.

[0269] Step S306 may refer to step S104 and will not be described in detail here.

[0270] S307: Determine whether the number of rotations detected by the feeding adjustment mechanism reaches the target number of rotations corresponding to the target liquid feeding amount, otherwise execute step S308, if yes, execute step S310.

[0271] As described above, when the counted number of rotations does not reach the target number of rotations corresponding to the target liquid addition amount, the volume of liquid pumped out by the driving unit has not yet reached the target liquid addition amount, so the driving unit needs to continue adding liquid.

[0272] When the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the volume of liquid extracted by the drive unit can be considered to be the target liquid addition amount. At this time, the drive unit can be controlled to stop and the liquid addition work is completed.

[0273] S308: The duration of no liquid flow detected by the feeding regulating mechanism reaches a preset value.

[0274] S309: The feeding regulating mechanism issues a liquid shortage alarm, controls the driving unit to stop, and subtracts the number of rotations during the duration of no liquid flow from the counted number of rotations and saves the result.

[0275] As described above, after the addition of liquid begins, when the duration of no liquid flow detected by the addition adjustment mechanism reaches a preset duration, it can be considered that the liquid in the seasoning box has been pumped out.

[0276] At this time, the feeding adjustment mechanism can issue a liquid shortage alarm, and can also control the drive unit to shut down, and subtract the number of rotations during the continuous period of no liquid flow from the counted number of rotations. By subtracting the number of rotations during the continuous period of no liquid flow from the currently counted number of rotations, the counted number of rotations can be made more accurate.

[0277] After the feeding adjustment mechanism issues a liquid shortage alarm, controls the drive unit to stop, and subtracts the number of rotations during the duration without liquid flow from the counted number of rotations, the feeding adjustment mechanism can continue to detect whether the drive unit is started. After detecting that the drive unit is started, it continues to execute the above-mentioned feeding control method to continue adding liquid.

[0278] The order of judging step S307 and judging step S308 can be interchanged or performed simultaneously. As long as the conditions of step S307 are met before step S308, step S309 can be executed when the conditions of step S308 are met.

[0279] S310: The feeding adjustment mechanism controls the driving unit to stop.

[0280] As described above, when the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the volume of liquid extracted by the drive unit can be considered to be the target liquid addition amount. At this time, the drive unit can be controlled to stop and the liquid addition work is completed.

[0281] After the driving unit is controlled to stop, the feeding adjustment mechanism can continue to detect whether the driving unit is started. After detecting that the driving unit is started, the feeding control method is continued to be executed, and the cycle repeats.

[0282] Moreover, the preset time lengths in the two situations where there is no liquid in the seasoning box and the liquid in the seasoning box cannot meet the target liquid addition amount can be the same or different.

[0283] Although the volume of liquid brought out by the drive unit during one rotation of the drive unit remains basically unchanged during one liquid addition process, after many liquid addition processes, as the usage time increases, the power of the drive unit's motor will continue to decrease, and the friction of the drive unit's hose will continue to increase. These will cause the actual unit liquid addition volume of the drive unit to continue to decrease.

[0284] Therefore, in one embodiment of the present disclosure, the feeding control method further includes, before the feeding adjustment mechanism calculates the target number of rotations that the driving unit of the feeding device needs to rotate based on the target liquid feeding amount and the set unit liquid feeding volume of the driving unit:

[0285] The feeding adjustment mechanism calibrates the set unit feeding volume of the drive unit.

[0286] For ease of understanding, refer to Figure 17 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0287] In this embodiment, the feeding control method includes the following steps: before the feeding adjustment mechanism detects that the driving unit is started, it may also include:

[0288] S401: The feeding adjustment mechanism calibrates the set unit liquid feeding volume of the driving unit.

[0289] By calibrating the set unit liquid addition volume of the driving unit, the gap between the set unit liquid addition volume of the driving unit and its actual unit liquid addition volume can be reduced, thereby improving the liquid addition accuracy.

[0290] Steps S402 to S407 refer to the above-mentioned steps S101 to S106 and are not described again here.

[0291] According to one embodiment of the present disclosure, in the feeding control method, the feeding adjustment mechanism calibrates the set unit liquid feeding volume of the driving unit, including:

[0292] The feeding adjustment mechanism amends the set unit liquid feeding volume of the driving unit based on the life attenuation curve of the driving unit and the recorded total working hours of the driving unit.

[0293] For ease of understanding, refer to Figure 18 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0294] In this embodiment, the feeding control method includes the following steps:

[0295] S501: The feeding adjustment mechanism records the total working time of the driving unit.

[0296] S502: The feeding adjustment mechanism corrects the set unit liquid feeding volume of the driving unit based on the life decay curve of the driving unit and the recorded total working time of the driving unit.

[0297] The total operating time of a drive unit is the cumulative operating time of the drive unit from the time it is put into use to the time calibration step S502 is executed. As described above, since the life decay of the same type of drive unit is substantially the same, the unit liquid filling volume can be calibrated based on the life decay curve of the drive unit. The method for obtaining the life decay curve of the drive unit can include obtaining the unit liquid filling volumes of multiple drive units of the same type at different total operating times, and fitting a scatter plot between the total operating time and the unit liquid filling volumes of the multiple drive units of the same type to obtain the life decay curve.

[0298] After recording the total operating hours of the drive unit, the dosing adjustment mechanism uses the previously acquired lifespan decay curve to adjust the set unit dosing volume of the drive unit to the unit dosing volume corresponding to the total operating hours in the lifespan decay curve. This calibration process is not only relatively simple, but also produces highly accurate results.

[0299] Since the volume of liquid extracted by the drive unit can be determined by the mass of the liquid extracted by the drive unit and the density of the liquid, and the above-mentioned rotation detection element, liquid detection element and control unit can be used to control the set number of rotations of the drive unit, the set unit liquid addition volume of the drive unit can be calibrated according to the mass of the liquid extracted by the set number of rotations of the drive unit and the density of the liquid.

[0300] According to one embodiment of the present disclosure, the charging adjustment mechanism calibrates the set unit charging volume of the driving unit, including:

[0301] The feeding adjustment mechanism corrects the set unit feeding volume of the driving unit based on the mass of the liquid extracted when the driving unit rotates a set number of times and the density of the liquid.

[0302] For ease of understanding, refer to Figure 19 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0303] In this embodiment, the feeding control method includes the following steps:

[0304] S601: The feeding adjustment mechanism controls the driving unit to rotate a set number of circles.

[0305] S602: The feeding adjustment mechanism corrects the set unit feeding volume of the driving unit based on the mass of the liquid extracted when the driving unit rotates a set number of times and the density of the liquid.

[0306] Before calibration, it is necessary to add a sufficient amount of liquid with a known density into the seasoning box, and then the drive unit can be controlled to rotate a set number of times. After controlling the drive unit to rotate a set number of times, the mass of the liquid extracted by the drive unit when it rotates a set number of times can be measured, and then the mass of the liquid extracted by the drive unit when it rotates a set number of times measured by the mass measuring element is divided by the density of the liquid to obtain the volume of the liquid extracted by the drive unit when it rotates a set number of times. Then the volume of the liquid extracted by the drive unit when it rotates a set number of times is divided by the set number of times to obtain the current unit liquid addition volume of the drive unit, and then the set unit liquid addition volume of the drive unit can be corrected to the current unit liquid addition volume. Since what is obtained is the current unit liquid addition volume of the drive unit currently in use, it is not affected by the error caused by the individual structural differences of the drive unit, so the obtained calibration result can be more in line with the actual working condition of the drive unit itself.

[0307] According to one embodiment of the present disclosure, the charging adjustment mechanism calibrates the set unit charging volume of the driving unit, including:

[0308] The feeding adjustment mechanism corrects the set unit liquid addition volume of the drive unit according to the slope of the liquid mass change curve. The liquid mass change curve is a curve between the mass of liquid extracted by the drive unit and the number of rotations of the drive unit. The feeding adjustment mechanism determines that the calibration has failed if the slopes of each point in the liquid mass change curve are not exactly the same.

[0309] For ease of understanding, refer to Figure 20 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0310] In this embodiment, the feeding control method includes the following steps:

[0311] S701: The feeding adjustment mechanism controls the rotation of the driving unit and obtains the liquid quality change curve.

[0312] The method for controlling the rotation of the driving unit by the feeding adjustment mechanism refers to the above method for controlling the driving unit to rotate a set number of times. The liquid mass change curve is a curve between the mass of the liquid extracted by the driving unit and the number of rotations of the driving unit.

[0313] As mentioned above, since the minimum unit of the number of rotations is 1 / nth of a circle, the minimum sampling interval of the liquid mass change curve is also 1 / nth of a circle.

[0314] Liquid mass change curve Figure 21 As shown, in Figure 21 In the figure, the portion where the mass of the liquid pumped out by the driving unit changes is the liquid mass change curve.

[0315] S702: Determine whether the slopes of the points in the liquid mass change curve are exactly the same. If not, execute step S703; if so, execute step S704.

[0316] S703: Determine that the calibration has failed.

[0317] Since the slope of each point in the liquid mass change curve represents the mass of liquid pumped out with each rotation of the control drive unit, if the slopes of the points in the liquid mass change curve are not exactly the same, it proves that the mass of liquid pumped out with each rotation of the drive unit is different. However, during a calibration process, the volume of liquid pumped out with each rotation of the drive unit is the same. This must be due to foreign matter mixed in the liquid, which causes the different mass of liquid pumped out with each rotation of the drive unit. Because of the foreign matter mixed in the liquid, the liquid mass change curve obtained this time will produce errors when used to set the unit liquid addition volume of the drive unit. Therefore, the calibration is judged to have failed. It is necessary to remove the foreign matter in the feeding device pipeline and recalibrate.

[0318] S704: The feeding adjustment mechanism corrects the set unit liquid feeding volume of the driving unit according to the slope of the liquid mass change curve.

[0319] When there's no foreign matter in the liquid, the slope of each point on the liquid mass change curve (the mass of liquid pumped by the drive unit divided by the number of rotations of the drive unit) is the mass of liquid pumped per rotation of the drive unit. This mass of liquid pumped per rotation is then divided by the density of the liquid to determine the current unit liquid volume of the drive unit. The set unit liquid addition volume of the drive unit is then corrected to the current unit liquid volume. Because this method obtains the liquid mass change curve for the currently used drive unit and is unaffected by errors caused by individual structural differences in the drive unit, the resulting calibration result is more accurately aligned with the actual operating conditions of the drive unit itself.

[0320] The present disclosure also provides another feeding control method, which is applied to a feeding device. The feeding device includes a seasoning box, a driving unit and a feeding adjustment mechanism. Please refer to the above description of the seasoning box and the driving unit, which will not be repeated here.

[0321] When the feeding regulating mechanism detects that the driving unit is started, it triggers the counting of the number of rotations of the driving unit;

[0322] When the number of rotations counted by the feeding regulating mechanism reaches the target number of rotations corresponding to the target liquid feeding amount, the driving unit is controlled to stop.

[0323] For ease of understanding, refer to Figure 22 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0324] In this embodiment, another feeding control method disclosed herein includes the following steps:

[0325] S801: Determine whether the feeding adjustment mechanism detects that the driving unit is started. If so, execute step S802; otherwise, return to continue executing step S801.

[0326] Since the liquid will be pumped out only after the driving unit is turned on, the feeding adjustment mechanism can trigger the counting of the number of rotations of the driving unit only when it detects that the driving unit is started.

[0327] S802: The feeding adjustment mechanism triggers the counting of the number of rotations of the driving unit.

[0328] When liquid is detected flowing through the fluid control element, the feeding adjustment mechanism starts counting the number of rotations of the driving unit. Specifically, the above-mentioned rotation detection element can be used to count the number of rotations of the driving unit.

[0329] S803: Determine whether the number of rotations detected by the feeding adjustment mechanism reaches the target number of rotations corresponding to the target liquid feeding amount. If so, execute step S804; otherwise, return to execute step S803.

[0330] S804: The feeding adjustment mechanism controls the driving unit to stop.

[0331] When the counted number of rotations does not reach the target number of rotations corresponding to the target liquid addition amount, the volume of liquid pumped out by the driving unit has not yet reached the target liquid addition amount, so the driving unit needs to continue adding liquid.

[0332] When the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, the volume of liquid extracted by the drive unit can be considered to be the target liquid addition amount. At this time, the drive unit can be controlled to stop and the liquid addition work is completed.

[0333] After the driving unit is controlled to stop, the feeding adjustment mechanism can continue to detect whether the driving unit is started, and after detecting that the driving unit is started, continue to execute subsequent steps, and repeat the process.

[0334] As can be seen, the feeding control mechanism in the disclosed feeding control method obtains the volume of liquid pumped by the drive unit by counting the number of rotations of the drive unit. Compared to existing adjustment methods that use the drive unit's rotation speed and rotation time to obtain the volume of liquid pumped by the drive unit, the disclosed feeding control method can avoid the impact of unstable drive unit rotation speed on liquid feeding accuracy, thereby improving the liquid feeding accuracy of the feeding control method.

[0335] The present disclosure also provides another feeding control method, which is applied to a feeding device. The feeding device includes a seasoning box, a driving unit and a feeding adjustment mechanism. Please refer to the above description of the seasoning box and the driving unit, which will not be repeated here.

[0336] The feeding regulating mechanism triggers counting of the number of rotations of the driving unit when detecting that liquid flows through the fluid control element;

[0337] The feeding regulating mechanism closes the fluid control element when the counted number of rotations reaches the target number of rotations corresponding to the target amount of liquid added;

[0338] The driving unit is continuously controlled to work, and all the liquid in the pipeline from the fluid control element to the pot body is drained into the pot body.

[0339] For ease of understanding, refer to Figure 23 , the above-mentioned feeding control method is described in detail with reference to an embodiment.

[0340] In this embodiment, the feeding control method includes the following steps:

[0341] S901: Determine whether the feeding adjustment mechanism detects that the driving unit is started. If so, execute step S902; otherwise, return to continue executing step S901.

[0342] S902: The feeding adjustment mechanism is triggered to detect whether liquid flows through the fluid control element.

[0343] S903: Determine whether the feeding adjustment mechanism detects that liquid flows through the fluid control element. If so, execute step S904; otherwise, return to execute step S903.

[0344] S904: The feeding adjustment mechanism triggers the counting of the number of rotations of the driving unit.

[0345] S905: Determine whether the number of rotations detected by the feeding adjustment mechanism reaches the target number of rotations corresponding to the target liquid feeding amount. If yes, execute step S906; otherwise, return to execute step S905.

[0346] Among them, steps S901 to S905 can refer to steps S101 to S105.

[0347] S906: The feeding regulating mechanism closes the fluid control element.

[0348] S907: The feeding adjustment mechanism continues to control the operation of the driving unit.

[0349] S908: Determine whether the liquid in the pipeline from the fluid control element to the pot body has been completely drained into the pot body. If so, execute step S909; otherwise, return to execute step S908.

[0350] S909: The liquid adding regulating mechanism controls the driving unit to stop.

[0351] It can be seen that in the feeding control method disclosed in the present invention, the feeding adjustment mechanism can first close the fluid control element when the counted number of rotations reaches the target number of rotations corresponding to the target liquid addition amount, and then control the drive unit to work until all the liquid in the pipeline from the fluid control element to the pot body is emptied into the pot body. In this way, when other liquids continue to be added, the liquid in the pipeline from the fluid control element to the pot body will not contain the previously added liquid, which can ensure that different liquids are mixed and avoid contamination between different liquids. Although the feeding device will add some more liquid, the amount of this liquid is relatively small and will not affect the normal cooking of the cooking equipment.

[0352] Application scenario 1 (sufficient liquid in the target seasoning box)

[0353] The user operates the display area on the cooking device and selects to execute a workflow including a liquid adding instruction;

[0354] After receiving the liquid addition command, the cooking device obtains a target number of rotations of the drive unit based on the target liquid addition amount of the liquid addition command, rotates the target seasoning box to dock with the buffer chamber based on the liquid addition command, and then turns on the drive unit. At this time, the fluid control element connects the seasoning box and the drive unit, and at the same time, the liquid detection element detects whether liquid is flowing through the fluid control element.

[0355] When the liquid flows through the fluid control element, the rotation detection element is triggered to count the number of rotations of the driving unit;

[0356] The liquid reaches the drive unit through the fluid control element and is pumped into the pot under the action of the drive unit;

[0357] When the counted number of rotations reaches the target number of rotations, it indicates that the volume of liquid drawn out by the driving unit has reached the target liquid addition amount, and the control unit controls the driving unit to stop, thereby completing the liquid addition task.

[0358] Repeat the above steps to perform the dosing task for another liquid.

[0359] Application scenario 2 (the target seasoning box is empty)

[0360] The user operates the display area on the cooking device and selects to execute a workflow including a liquid adding instruction;

[0361] After receiving the liquid addition command, the cooking device obtains a target number of rotations of the drive unit based on the target liquid addition amount of the liquid addition command, rotates the target seasoning box to dock with the buffer chamber based on the liquid addition command, and then turns on the drive unit. At this time, the fluid control element connects the seasoning box and the drive unit, and at the same time, the liquid detection element detects whether liquid is flowing through the fluid control element.

[0362] When the duration of no liquid flow detected by the feeding adjustment mechanism reaches a preset value, it indicates that the target seasoning box is empty, that is, there is no liquid in the target seasoning box. At this time, the feeding adjustment mechanism issues a liquid shortage alarm and controls the drive unit to shut down.

[0363] The user is notified of the lack of liquid alarm, and after adding liquid to the target seasoning box, the drive unit restarts and refills the liquid.

[0364] Application scenario 3 (the amount of liquid in the target seasoning box is insufficient to reach the target liquid addition amount)

[0365] The user operates the display area on the cooking device and selects to execute a workflow including a liquid adding instruction;

[0366] After receiving the liquid addition command, the cooking device rotates the target seasoning box until it mates with the buffer chamber according to the liquid addition command. Then, based on the target liquid addition amount in the liquid addition command, the target number of rotations of the drive unit is determined. Based on the liquid addition command, the drive unit is turned on. At this point, the fluid control element connects the seasoning box and the drive unit, and simultaneously, the liquid detection element detects whether liquid is flowing through the fluid control element.

[0367] When liquid flows through the fluid control element, the rotation detection element starts to detect the number of rotations of the driving unit;

[0368] Before the number of rotations of the driving unit reaches the target number of rotations, if the duration of no liquid flowing through the fluid control element detected by the feeding adjustment mechanism reaches a preset value, it means that the amount of liquid in the target seasoning box is insufficient, the feeding adjustment mechanism will issue a liquid shortage alarm, control the driving unit to stop, and save

[0369] When the user receives the liquid shortage alarm and adds liquid to the target seasoning box, the feeding device restarts the drive unit and continues to add liquid, and counts based on the current number of rotations until the number of rotations reaches the target number of rotations. At this time, the target liquid adding task is completed.

[0370] Application Scenario 4 (Calibration using the total operating time of the drive unit)

[0371] The user operates the display area on the cooking device to select to perform the calibration process, or the cooking device performs the calibration process by itself after working for a period of time;

[0372] When the cooking equipment is executing the calibration process, the feeding adjustment mechanism corrects the set unit liquid adding volume of the driving unit to the unit liquid adding volume value corresponding to the total working time in the life decay curve based on the total working time of the driving unit and the life decay curve of the driving unit, wherein the total working time of the driving unit is the cumulative working time of the driving unit from the start of being put into use to the execution of the calibration process.

[0373] Application Scenario 5 (Calibration using the weight and density of the liquid pumped out of the drive unit)

[0374] After adding a sufficient amount of calibration liquid to the seasoning box, the user operates the display area on the cooking device to select to execute the calibration process;

[0375] The cooking device activates the drive unit, and the liquid detection element detects whether liquid is flowing. If the liquid detection element detects liquid flowing, the control unit triggers the rotation detection element to count the number of rotations of the drive unit. When the counted number of rotations reaches a set number, the control unit stops the drive unit, and the mass measurement element measures the mass of the calibration liquid in the pot.

[0376] The cooking device obtains the current unit liquid volume of the driving unit according to formula (2):

[0377]

[0378] Where V is the current unit liquid volume of the driver unit, m is the mass of the calibration liquid in the pot measured by the mass measuring element, ρ is the density of the calibration liquid, and T is the set number of revolutions. Finally, the set unit liquid volume of the driver unit is corrected to the current unit liquid volume.

[0379] Application Scenario 6 (Adding an emptying step during the dosing process)

[0380] The user operates the display area on the cooking device and selects to execute a workflow including a liquid adding instruction;

[0381] After receiving the liquid addition command, the cooking device obtains a target number of rotations of the drive unit based on the target liquid addition amount of the liquid addition command, rotates the target seasoning box to dock with the buffer chamber based on the liquid addition command, and then turns on the drive unit. At this time, the fluid control element connects the seasoning box and the drive unit, and at the same time, the liquid detection element detects whether liquid is flowing through the fluid control element.

[0382] When the liquid flows through the fluid control element, the rotation detection element is triggered to count the number of rotations of the driving unit;

[0383] The liquid reaches the drive unit through the fluid control element and is pumped out from the inlet end of the drive unit's hose into the pot body under the rotation and squeezing action of the pressure roller on the drive unit's pump wheel;

[0384] When the counted number of rotations reaches the target number of rotations, the fluid control element is closed;

[0385] The driving unit continues to work until all the liquid in the pipeline of the cooking device is drained into the pot body, thus completing the feeding task for one liquid.

[0386] Repeat the above steps to perform the dosing task for another liquid.

[0387] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
