[0037] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0038] Example 1

[0039] refer to Figure 1 The present embodiment provides an automatic feeding device for liquid seasoning, comprising a seasoning box 1 for holding liquid seasoning, a transfer box 2, a power assembly (not shown in the figure) and a controller (not shown in the figure). In the present embodiment, there are five seasoning boxes 1, each of which has a liquid inlet and a liquid outlet, and each seasoning box 1 holds a different type of liquid seasoning, wherein the liquid seasoning can be a conventional liquid seasoning, such as soy sauce, cooking oil, vinegar, cooking wine, etc., or a solid seasoning (or seasoning that is not easy to flow) dissolved in water and used as a liquid seasoning, such as water starch, salt water, and diluted sauce.

[0040] The feed inlet of transfer box 2 is connected to the liquid outlet of each seasoning box 1, and is used to receive the liquid seasoning flowing out of any seasoning box 1. A weighing detection component (not shown) is provided at the bottom of transfer box 2. This weighing detection component is used to weigh the seasoning in transfer box 2. The seasoning weight can be the amount of liquid seasoning flowing into transfer box 2 or the amount of liquid seasoning flowing out of transfer box 2.

[0041] The power assembly is used to transport the liquid seasoning in each seasoning box 1 to the transfer box 2. In this embodiment, the power assembly includes a first power source 31. A first power source 31 is respectively provided between the feed port of the transfer box 2 and the liquid outlet of each seasoning box 1. That is, the number of first power sources 31 is the same as the number of seasoning boxes 1, and the two are arranged in a one-to-one correspondence so that the transfer box 2 can be connected to different seasoning boxes 1 through different first power sources 31. In other embodiments, the number of first power sources 31 can be designed to be one, and the feed port of the transfer box 2 is respectively connected to the liquid outlets of all seasoning boxes 1 through the same first power source 31, so that all seasoning boxes 1 share one first power source 31. In this case, a solenoid valve or a manual switch valve can be added to the liquid outlet of each seasoning box 1.

[0042] The second power source 4 is connected to the discharge port of the transfer box 2 and the discharge mechanism 5, respectively, for delivering the liquid seasoning in the transfer box 2 to the cooking pot via the discharge mechanism 5. In this embodiment, the first power source 31 and the second power source 4 can each be a peristaltic pump, an electromagnetic pump, a diaphragm pump, or a vacuum pump. The controller is electrically connected to the first power source 31 and the second power source 4 in the weighing detection assembly and the power assembly.

[0043] Furthermore, each seasoning box 1 is provided with a liquid level detection assembly (not shown) for detecting liquid parameters, including liquid pressure and / or liquid height; a controller is electrically connected to the liquid level detection assembly and is configured to calculate the remaining weight in the seasoning box 1 and / or the actual amount of material discharged from the seasoning box 1 based on the liquid level parameters. Of course, a liquid level detection assembly (not shown) for detecting liquid parameters may also be provided on the transfer box 2, and the controller may calculate the actual amount of material fed into the transfer box 2 based on the liquid level parameters. In this case, the liquid level detection assembly on each seasoning box 1 may or may not be omitted.

[0044] refer to Figure 4 This embodiment further provides a control method for a liquid seasoning automatic feeding device, which uses the liquid seasoning automatic feeding device described above. The control method includes the following steps:

[0045] S1, start the automatic feeding device for liquid seasoning;

[0046] S2, obtaining seasoning information for cooking food, the seasoning information including at least one of seasoning type, set amount, start time, and order of seasoning;

[0047] Specifically, after starting the device, the user selects the food to be cooked according to cooking needs, and the controller in the device determines the seasoning information based on the food to be cooked, where the seasoning information includes at least one of the seasoning type, set amount, start time and order of seasoning.

[0048] S3, when the start time of any seasoning is reached, the power component is started to transfer the liquid seasoning in the seasoning box 1 containing the seasoning to the transfer box 2;

[0049] Specifically, assuming that a variety of different seasonings need to be added, the order of adding all the seasonings is different, and they are arranged in the order of the first seasoning, the second seasoning, and the last seasoning. Correspondingly, the seasoning box containing the first seasoning is the first seasoning box, the seasoning box containing the second seasoning is the second seasoning box, and the seasoning box containing the last seasoning is the last seasoning box. In this embodiment, the power assembly includes a first power source 31. The number of the first power source 31 is equal to that of the seasoning box 1 and they are arranged one-to-one. Figure 1 .

[0050] When the controller detects that the first seasoning reaches the start time of addition, the first power source 31 corresponding to the first seasoning or the first seasoning box is started, and the first power source 31 transports the first seasoning in the first seasoning box to the transfer box 2.

[0051] S4, obtaining the weight of the seasoning in the transfer box 2, and obtaining the liquid level parameters of the transfer box 2 or the seasoning box 1 containing the seasoning, the liquid level parameters including the liquid pressure and / or the liquid height;

[0052] Specifically, while starting the first power source 31 corresponding to the first seasoning or the first seasoning box, the weight of the seasoning in the transfer box 2 is obtained through the weighing detection component. The weight of the seasoning at this time is the weight of the first seasoning flowing into the transfer box 2; and the liquid level parameters of the transfer box 2 or the seasoning box 1 containing the seasoning are obtained through the liquid level detection component, so as to obtain the liquid level parameters of the first seasoning box 1 through the liquid level detection component on the first seasoning box 1. The liquid level parameters include the liquid height. The controller can calculate the remaining weight of the first seasoning box 1 and / or the actual discharge amount flowing out of the first seasoning box 1 based on the liquid height.

[0053] In step S5 , when the weight of the seasoning in the transfer box 2 reaches the set amount of the seasoning, the power assembly is turned off, and then the second power source 4 is started to transfer the liquid seasoning in the transfer box 2 to the cooking pot.

[0054] Specifically, in S51, when the weight of the seasoning obtained by the controller through the weighing detection component reaches the set amount of the first seasoning, the first power source 31 is turned off, and the first seasoning is now added to the transfer box 2.

[0055] In this embodiment, the on / off control of the second power source 3 includes but is not limited to any of the following methods:

[0056] In the first method, S52, after the first seasoning is dispensed into transfer box 2, second power source 4 is activated to deliver the first seasoning from transfer box 2 to outlet mechanism 5 located near the cooking pot, where it then flows into the cooking pot. Once the first seasoning in transfer box 2 has been dispensed, second power source 4 is deactivated. Alternatively, this determination can be based on whether second power source 4 is idling, or by determining whether the amount discharged from transfer box 2 is greater than or equal to the set amount of the first seasoning, as determined by a weighing detection component.

[0057] When the controller detects that the time has come to begin dosing the second, third, and so on, seasoning, it then dispenses the second, third, and so on seasoning according to the dosing logic for the first seasoning (i.e., steps S1 to S52), and so on, until all required seasonings have been dispensed, automatically ending the dosing process. In this manner, the second power source 3 is turned on and off as many times as the number of seasonings to be dispensed.

[0058] In the second method, S53, after the first seasoning is added to transfer box 2, if the controller detects that it is time to start adding the second, third, and finally, seasoning, the controller then adds the second, third, and finally seasoning according to the same logic as for the first seasoning (i.e., steps S1 to S51), until all required seasonings have been added to transfer box 2. The seasonings can then be mixed evenly, or optionally stirred, before the second power source 3 is activated to transport all seasonings in transfer box 2 to the outlet mechanism 5 located near the cooking pot, completing the automatic feeding process. In this method, the second power source 3 is turned on and off only once, saving energy while reducing its workload and extending its service life.

[0059] refer to Figure 5 , further, the control method also includes:

[0060] S61, calculating the actual discharge amount according to the liquid level parameter;

[0061] S62: Determine whether the weighing detection component needs to be calibrated based on the relationship between the weight of the seasoning in the transfer box 2 and the set value, wherein the set value is ±10% of the actual discharge amount.

[0062] Specifically, after step S52, the actual discharge amount of the first seasoning box 1 is calculated based on the liquid level parameters of the first seasoning box 1, and then it is determined whether the weight of the seasoning in the transfer box 2 is within the set value range. If so, it is determined that the weighing detection component does not need to be calibrated. Optionally, in order to further improve the detection accuracy, it is possible to separately detect and determine whether the weight of the seasoning flowing from each seasoning box 1 into the transfer box 2 is within the range of ±10% of the actual discharge amount of each seasoning box 1. If more than half (or not less than 2 / 3) are within the range, it is further determined that the weighing detection component does not need to be calibrated. Otherwise, the weighing detection component needs to be calibrated. Thus, by cooperating with the weighing detection component at the bottom of the transfer box 2 and the liquid level detection component on the seasoning box 1, it is possible to determine whether the weighing detection component needs to be calibrated, thereby making the feeding accuracy of the device higher.

[0063] Example 2

[0064] refer to Figure 2This embodiment differs from the first embodiment in that the power components are different, and the device further includes an air pressure detection component. In this embodiment, there are five seasoning boxes 1, and the liquid outlets of all seasoning boxes 1 are directly connected to the feed inlet of the same transfer box 2. A weighing detection component (not shown) is provided at the bottom of the transfer box 2. This weighing detection component is used to weigh the weight of the seasoning in the transfer box 2, where the weight of the seasoning can be the amount of liquid seasoning flowing into the transfer box 2 or the amount of liquid seasoning flowing out of the transfer box 2. The second power source 4 is respectively connected to the discharge port of the transfer box 2 and the discharge mechanism 5, and is used to transport the liquid seasoning in the transfer box 2 to the cooking pot through the discharge mechanism 5.

[0065] The power assembly is used to transport the liquid seasoning in each seasoning box 1 to the transfer box 2. In this embodiment, the power assembly includes a gas generator 32 and a control switch 33. The gas generator 32 is an air pump electrically connected to the controller. The air outlet of the gas generator 32 or the air pump is respectively connected to the air inlet of all the seasoning boxes 1.

[0066] The control switch 33 can be a solenoid valve electrically connected to the controller, or it can be a manual switch valve. In this embodiment, the control switch 33 is taken as a solenoid valve as an example. A control switch 33 is provided between the air outlet of the gas generator 32 and the air inlet of each seasoning box 1, that is, the number of control switches 33 is the same as the number of seasoning boxes 1, and the two are arranged in a one-to-one correspondence, so that the gas generator 32 can be connected to the air inlets of different seasoning boxes 1 through different control switches 33.

[0067] refer to Figure 2 The power assembly also includes a first one-way valve 34, which is provided between the gas outlet of the gas generator 32 and the control switch 33. The first one-way valve 34 is a gas one-way valve, which is used to guide the air flowing out of the gas generator 32 to any control switch 33 in one direction. In this way, when the gas generator 32 (i.e., the air pump) is switched from start to stop, it can prevent the formation of negative pressure inside the seasoning box 1, thereby preventing the liquid seasoning flowing into the transfer box 2 from being drawn back into the seasoning box 1. Of course, the power assembly can also include a second one-way valve 35, which is provided at the liquid outlet of each seasoning box 1. The second one-way valve 35 is a liquid one-way valve, which is used to guide the liquid seasoning flowing out of the seasoning box 1 into the transfer box 2 in one direction. In this way, even if negative pressure is formed inside the seasoning box 1, it can effectively prevent the liquid seasoning in the transfer box 2 from being drawn back into the seasoning box 1.

[0068] Furthermore, each seasoning box 1 is provided with a liquid level detection component (not shown in the figure) for detecting liquid parameters, and the liquid level parameters include liquid pressure and / or liquid height; the controller is electrically connected to the liquid level detection component, and is used to calculate the remaining weight in the seasoning box 1 and / or the actual discharge amount flowing out of the seasoning box 1 based on the liquid level parameters.

[0069] Furthermore, each seasoning box 1 is provided with an air pressure detection component (not shown in the figure) for detecting the internal pressure thereof, and the controller is electrically connected to the air pressure detection component.

[0070] In this embodiment, a switch valve for controlling the opening and closing of the feed inlet of transfer box 2 is provided. This switch valve can be configured to automatically open the feed inlet of transfer box 2 when pressure is greater than or equal to a valve opening threshold, allowing the liquid seasoning in seasoning box 1 to be discharged into the transfer box under the action of air pressure; or to automatically close the feed inlet of transfer box 2 when pressure is less than the valve opening threshold, preventing the liquid seasoning in seasoning box 1 from flowing into the transfer box. Of course, the switch valve can also be configured as an electric switch valve.

[0071] refer to Figure 4 This embodiment further provides a control method for a liquid seasoning automatic feeding device, which uses the liquid seasoning automatic feeding device described above. The control method includes the following steps:

[0072] S1, start the automatic feeding device for liquid seasoning;

[0073] S2, obtaining seasoning information for cooking food, the seasoning information including at least one of seasoning type, set amount, start time, and order of seasoning;

[0074] Specifically, after starting the device, the user selects the food to be cooked according to cooking needs, and the controller in the device determines the seasoning information based on the food to be cooked, where the seasoning information includes at least one of the seasoning type, set amount, start time and order of seasoning.

[0075] S3, when the start time of any seasoning is reached, the power component is started to transfer the liquid seasoning in the seasoning box 1 containing the seasoning to the transfer box 2;

[0076] Specifically, assuming that a variety of different seasonings need to be added, the order of adding all the seasonings is different, and they are arranged in the order of the first seasoning, the second seasoning, and the last seasoning. Correspondingly, the seasoning box containing the first seasoning is the first seasoning box, the seasoning box containing the second seasoning is the second seasoning box, and the seasoning box containing the last seasoning is the last seasoning box. In this embodiment, the power component includes an air generator 32 and multiple control switches 33 (such as solenoid valves). The number of control switches 33 is equal to that of seasoning boxes 1 and they are arranged one-to-one. Figure 2 .

[0077] When the controller detects that the first seasoning has reached the start time, it starts the air generator 32 and opens the control switch 33 corresponding to the first seasoning or the first seasoning box. At this time, the other control switches 33 are in the closed state. The air generator 32 drives air into the first seasoning box through the corresponding control switch 33. As air continues to enter the first seasoning box, the internal pressure increases, thereby driving the first seasoning in the first seasoning box to flow out.

[0078] In this embodiment, the specific steps of transferring the liquid seasoning in the seasoning box 1 containing the seasoning to the transfer box 2 include:

[0079] S31, obtaining pressure information of the seasoning box 1 of the seasoning product, the pressure information including internal pressure and liquid pressure;

[0080] Specifically, the liquid pressure of the first seasoning box is obtained by a liquid level detection component on the first seasoning box, and the internal pressure of the first seasoning box is obtained by a pressure detection component on the first seasoning box;

[0081] S32 , determining whether the sum of the internal pressure and the liquid level pressure reaches a valve opening threshold; if so, the switch valve in the transfer box 2 is opened, and the liquid seasoning flows into the transfer box 2 .

[0082] Specifically, when the sum of the internal pressure and the liquid level pressure reaches the valve opening threshold, the on-off valve in transfer box 2 opens, and the first seasoning in the first seasoning box 1 flows into transfer box 2. Thus, by controlling the opening and closing of the on-off valve in transfer box 2 based on the relationship between the sum of the internal pressure and the liquid level pressure and the valve opening threshold, this ensures that after transfer box 2 is opened, the liquid seasoning can flow into transfer box 2 more stably, which helps improve the weighing accuracy at transfer box 2.

[0083] S4, obtaining the weight of the seasoning in the transfer box 2, and obtaining the liquid level parameters of the transfer box 2 or the seasoning box 1 containing the seasoning, the liquid level parameters including the liquid pressure and / or the liquid height;

[0084] Specifically, while starting the air generator 32 corresponding to the first seasoning or the first seasoning box, the weight of the seasoning in the transfer box 2 is obtained through the weighing detection component. The weight of the seasoning at this time is the weight of the first seasoning flowing into the transfer box 2; and the liquid level parameters of the transfer box 2 or the seasoning box 1 containing the seasoning are obtained through the liquid level detection component, so as to obtain the liquid level parameters of the first seasoning box 1 through the liquid level detection component on the first seasoning box 1. The liquid level parameters include the liquid height. The controller can calculate the remaining weight of the first seasoning box 1 and / or the actual discharge amount flowing out of the first seasoning box 1 based on the liquid height.

[0085] In step S5 , when the weight of the seasoning in the transfer box 2 reaches the set amount of the seasoning, the power assembly is turned off, and then the second power source 4 is started to transfer the liquid seasoning in the transfer box 2 to the cooking pot.

[0086] Specifically, in S51, when the weight of the seasoning obtained by the controller through the weighing detection component reaches the set amount of the first seasoning, the air generator 32 and the control switch 33 corresponding to the first seasoning box are turned off, and the first seasoning is put into the transfer box 2.

[0087] In this embodiment, the on / off control of the second power source 3 includes but is not limited to any of the following methods:

[0088] In the first method, S52, after the first seasoning is dispensed into the transfer box 2, the second power source 4 is activated to transport the first seasoning from the transfer box 2 to an outlet mechanism 5 located near the cooking pot. The seasoning then flows from the outlet mechanism 5 into the cooking pot. After the first seasoning in the transfer box 2 is dispensed, the second power source 4 is turned off. Alternatively, this can be determined based on whether the second power source 4 is idling, or when the weighing detection component detects that the discharge volume from the transfer box 2 is greater than or equal to the set dispensing volume for the first seasoning. If so, the first seasoning is dispensed. When the controller detects that the start time for dispensing the second, third, and last seasonings has arrived, the second, third, and last seasonings are dispensed according to the dispensing logic for the first seasoning (i.e., steps S1 to S52), until all required seasonings are dispensed, and the automatic dispensing process ends.

[0089] In the second method, S53, after the first seasoning is added to the transfer box 2, if the controller detects that the time has come to start adding the second, third, and finally, seasoning, the controller then adds the second, third, and finally, seasoning according to the same logic as for the first seasoning (i.e., steps S1 to S51), until all required seasonings are added to the transfer box 2. The seasonings can then be mixed evenly, or optionally, before the second power source 3 is activated to transport all seasonings in the transfer box 2 to the outlet mechanism 5 located near the cooking pot, completing the automatic feeding process.

[0090] refer to Figure 5 , further, the control method also includes:

[0091] S61, calculating the actual discharge amount according to the liquid level parameter;

[0092] S62: Determine whether the weighing detection component needs to be calibrated based on the relationship between the weight of the seasoning in the transfer box 2 and the set value, wherein the set value is ±10% of the actual discharge amount.

[0093] Specifically, after step S52, the actual discharge volume of the first seasoning box 1 is calculated based on the liquid level parameters of the first seasoning box 1. It is then determined whether the weight of the seasoning in the transfer box 2 is within a set value range. If so, it is determined that the weighing and detection assembly does not need to be calibrated. Optionally, to further improve detection accuracy, the weight of the seasoning flowing from each seasoning box 1 into the transfer box 2 can be individually detected and determined to be within a range of ±10% of the actual discharge volume of each seasoning box 1. If more than half (or not less than 2 / 3) are within the range, it is further determined that the weighing and detection assembly does not need to be calibrated. Otherwise, the weighing and detection assembly needs to be calibrated.

[0094] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
