Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a weighing method of a food processor and the food processor. Background Art

[0002] With the progress of society and the development of science and technology, more and more food processing machines have emerged on the market, and many types of food processing machines have greatly facilitated people's daily lives. However, most of the current food processing machines do not have a weighing function, so they cannot identify the amount of material placed by the user, which may cause the amount of material placed by the user during pulping to not match the amount of pulping water. When the amount of material is too much and the amount of pulping water is too little, on the one hand, the machine may not be able to completely crush the material, seriously affecting the pulping effect and taste of the pulp; on the other hand, too much material will put a greater load on the machine's motor and other driving devices, reducing the life of the motor, and too much material is likely to increase the noise of the pulping process, which is not conducive to user experience. When the amount of material is too little and the amount of pulping water is too much, not only will the slurry prepared by the machine be insufficiently concentrated, but there is also a risk of slurry overflow, which will also affect the taste of the slurry and user experience.

[0003] Furthermore, existing food processors, in addition to being unable to identify the amount of material, typically also cannot identify the amount of water used for pulping. If the machine runs out of water during pulping, a common practice is to add water a second time. However, this second addition often requires interrupting the continuous pulping process, which impacts the pulping process to some extent, is less user-friendly, and results in a poor user experience.

[0004] This shows that the existing technology needs to be further improved and enhanced. Summary of the Invention

[0034] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] In addition, in the description of the present invention, it should be understood that the terms "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0038] In the present invention, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0039] like Figure 1As shown, the present invention provides a food processor, comprising a main unit 100 with a weighing function, a detachable component 110 removably mounted on the main unit 100, and the main unit 100 including a fixed component 120 and a main control chip (not shown). The fixed components in this embodiment may be, for example, a blending cup, a drive motor, and a pulp discharge rotary valve, all of which are fixed to the body of the food processor; the detachable component 110 may, for example, include an upper cover 111 and a water tank 112, the upper cover 111 being used to open or close the processing chamber of the blending cup; the water tank 112 can provide water for the pulping process of the food processor, and since the water tank 112 is detachable, it is convenient for the user to add water to or pour out the water in the water tank 112.

[0040] In addition, the food processor provided by the present invention may further include a position detection element (not shown in the figure), which includes a first detection portion (not shown in the figure) provided on the main unit 100 and a second detection portion (not shown in the figure) correspondingly provided on the detachable component 110. The first detection portion and the second detection portion cooperate to detect whether the detachable component 110 is properly assembled. The provision of the position detection element enables real-time detection of the assembly status of the detachable component 110, thereby facilitating the machine to execute the weighing method described below, facilitating accurate measurement of material weight and water weight, and improving the pulping effect of the machine.

[0041] It should be noted that the position detection element in this embodiment can have a variety of different implementations. Specifically, for example, the first detection part can be a magnet provided on the water tank 112 and the upper cover 111, and the second detection part can be a Hall element or a reed switch that can cooperate with the magnet; the first detection part can also be a protrusion provided on the water tank 112 and the upper cover 111, and the second detection part can also be a micro switch that can cooperate with the protrusion; in addition, the first detection part can also be a metal contact provided on the water tank 112 and the upper cover 111, and the second detection part can also be a pin provided corresponding to the metal contact; and the positions of the first detection part and the second detection part can also be interchangeable.

[0042] In this way, the coordination between the first and second detection units enables the food processing machine to accurately detect the assembly status of detachable components 110, such as the upper cover 111 and the water tank 112. When the upper cover 111 and the water tank 112 are placed in the machine, the first and second detection units can coordinate, and the position detection element can send a detection signal to the main control chip. When the upper cover 111 and the water tank 112 are not placed in the machine, the first and second detection units cannot coordinate, and the position detection element cannot send a detection signal to the main control chip. The main control chip determines the assembly status of the detachable component 110 based on the presence or absence of the detection signal, which can ensure the reliability of the position detection of the detachable component 110 and improve the intelligence of the machine.

[0043] Furthermore, since the detachable component 110 often requires frequent removal and placement, and this frequent removal and placement can significantly impact the weighing process of the food processor described below, this embodiment allows the position detection element to detect the status of the detachable component 110 at regular intervals, t, thereby improving the sensitivity of the position detection element and reducing potential detection errors. The time t is preferably 1 second, and this embodiment does not limit the specific value of the time t.

[0044] In one embodiment, referring to Figure 2-4 As shown, the present invention also provides a weighing method for a food processor, which may include at least the following steps:

[0045] (a) Material adding stage: adding materials into the host 100.

[0046] (b) In-place detection stage: according to the assembly status of the detachable component 110 , the weight of the detachable component 110 is determined.

[0047] (c) Material weighing stage: The main control chip calculates the weight of the material based on the weight of the detachable component 110, the weight of the fixed component and the weight of the entire machine after it is in place.

[0048] (d) Water weighing stage: the main control chip calculates the weight of the water based on the weight of the detachable component 110, the weight of the fixed component, the weight of the material, and the weight of the entire machine after it is in place.

[0049] (e) Slurrying stage: the material and water are stirred and mixed to prepare a slurry.

[0050] It should be noted that in the food processor provided in this embodiment, since the blending cup is a fixed component, when the water tank 112 in the detachable component 110 is in the assembled state, the main control chip cannot simultaneously identify the weight of the material in the blending cup and the amount of water in the water tank 112. Therefore, preferably, this embodiment can first weigh the weight of the material and then weigh the amount of water. Furthermore, during the entire weight calculation process, the main control chip monitors the assembly status of the upper cover 111 and water tank 112 in the detachable component 110 in real time.

[0051] In addition, in order to make the host 100 have a weighing function, for example, one or more weighing sensors can be set at the bottom of the host 100 to perform weighing calculations. In addition, the main control chip in this embodiment pre-stores the weight M of the upper cover 111. 上 , the weight M of the empty water tank 112 箱 、Total weight of water tank 112 M 水总 , the weight of the fixed component M固 , the weight M of the whole machine after the detachable component 110 is in place, and the initial weight M of the whole machine detected by the weighing sensor when the machine is powered on 初 .

[0052] Furthermore, during the in-place detection phase, since there are various assembly conditions for the detachable component 110, the detachable component 110 has different weights in different conditions. Specifically:

[0053] ① When the upper cover 111 and the water tank 112 are not placed, the position detection element has no detection signal, and thus the weight of the detachable component 110 is zero.

[0054] ② When the upper cover 111 is not placed and the water tank 112 is placed, the position detection element can detect the signal of the water tank 112. At this time, the main control chip prompts the user to remove the water tank 112, and until the position detection element can no longer detect the signal of the water tank 112, the main control chip calculates M 水总 =M 初 -M. It should be noted here that before the machine starts pulping, the user is often required to add water to the water tank 112. However, since the amount of water cannot be directly weighed, it is necessary to use M 初 The difference between M and M 水总 Calculate. Among them, M 初 M corresponds to the weight of the whole machine when the water tank 112 is placed, and M corresponds to the weight of the whole machine when the water tank 112 is removed.

[0055] ③ When the upper cover 111 is placed and the water tank 112 is not placed, the position detection element can detect the signal of the upper cover 111. At this time, the weight of the detachable component 110 is M 上 .

[0056] ④ When the upper cover 111 and the water tank 112 are placed, the position detection element can detect the signal of the water tank 112 and the signal of the upper cover 111. At this time, the weight of the detachable component 110 is M 上 +M 水总 =M 上 +M 初 -M. It should be noted that M represents the real-time weight of the entire machine, a value that changes with the assembly state of the detachable component 110 and the weight of the material. Therefore, the actual value of M in this case is different from that in the second case.

[0057] As a preferred embodiment of the present invention, the weight of the material is the difference between the weight of the entire machine after it is in place and the weight of the detachable component 110 and the weight of the fixed component. Accordingly, since there are many different assembly conditions of the detachable component 110 during the material weighing stage, the weight of the material M in different conditions 物There are many ways to calculate , specifically:

[0058] (1) When the upper cover 111 is not placed and the water tank 112 is not placed, the position detection element has no detection signal and the weight of the detachable component 110 is zero, then M 物 =M 初 -M 固 .

[0059] (2) When the upper cover 111 is not placed and the water tank 112 is placed, the position detection element can detect the signal of the water tank 112, and the weight of the detachable component 110 is M 水总 =M 初 -M, then M 物 =M 初 -M 固 -M 水总 .

[0060] (3) When the upper cover 111 is placed and the water tank 112 is not placed, the position detection element can detect the signal of the upper cover 111, and the weight of the detachable component 110 is M 上 , then M 物 =M 初 -M 固 -M 上 .

[0061] (4) When the upper cover 111 and the water tank 112 are placed, the position detection element can detect the water tank 112 signal and the upper cover 111 signal. The weight of the detachable component 110 is M 上 +M 水总 =M 上 +M 初 -M, then M 物 =M 初 -M 固 -M 水总 -M 上 .

[0062] Reference Figure 2-Figure 5 As shown, preferably, between the material weighing stage and the water weighing stage, the weighing method may further include:

[0063] Material detection stage: the main control chip detects whether the weight of the material is within a preset first range; if so, the food processor continues to work; if not, the user is prompted to take out or add some material and returns to the in-place detection stage.

[0064] In the material detection stage, if the first range is assumed to be [M 物min , M 物max ], then the main control chip is M 物 When judging the size of , there are several situations:

[0065] When M 物max ≥M 物 ≥M 物min When the position detection element continuously detects the assembly status of the water tank 112 and the upper cover 111, and when the upper cover 111 signal is not detected, the user is prompted to place the upper cover 111. If the upper cover 111 signal is detected, the water tank 112 signal is detected; when the water tank 112 signal is not detected, the user is prompted to place the water tank 112. If the water tank 112 signal is detected, the food processor continues to execute subsequent steps.

[0066] When M 物 >M 物max When the user places too much material, the machine prompts the user to take out some of the material and returns to the in-place detection stage until M 物 When within the first range, the machine continues to perform subsequent steps.

[0067] When M 物 <M 物min When the user places too little material, the machine prompts the user to add some material and returns to the in-place detection stage until M 物 When within the first range, the machine continues to perform subsequent steps.

[0068] After the material detection phase is completed, the machine enters the water weighing phase. At this time, since the water tank 112 and the upper cover 111 have been placed on the host 100, the main control chip can calculate the weight of the water M according to the weight of the detachable component 110, the weight of the fixed component, the weight of the material, and the weight of the entire machine after it is in place. 水 Specifically, M 水 =MM 非 -M 箱 -M 物 -M 上 .

[0069] This embodiment can calculate the weight of the material and the weight of the water by using the weight of the entire machine after it is in place, the weight of the detachable component 110, and the weight of the fixed component. This weight calculation method is simple in logic, and the weight of the material and the weight of the water can be determined only by difference calculation, thereby avoiding interference with the calculation process caused by too many times of taking and putting materials or water, and thus helping to reduce errors in the weight calculation process, thereby greatly improving the calculation efficiency and accuracy of the weight of the food processor.

[0070] Furthermore, after the water weighing stage, the weighing method may further include:

[0071] Water quantity detection stage: the main control chip detects whether the weight of the water is within a preset second range; if so, the food processor continues to work; if not, the user is prompted to remove or add some water, and the process returns to the in-place detection stage.

[0072] In the water volume detection phase, if the second range is assumed to be [M 水min , M 水max ], then the main control chip is M 水 When judging the size of , there are several situations:

[0073] When M 水max ≥M 水 ≥M 水min , the food processor continues with the next steps.

[0074] When M 水 >M 水max When the amount of water placed by the user is too much, the machine prompts the user to take out some water, and the machine continues to operate until M 水 When in the second range, the machine continues to perform subsequent steps.

[0075] When M 水 <M 水min When the amount of water placed by the user is too little, the machine prompts the user to add some water, and the amount of water remains until M 水 When in the second range, the machine continues to perform subsequent steps.

[0076] As a preferred embodiment of the present invention, the water level detection stage may further include: within a preset time T, detecting whether the water tank 112 is assembled in place to determine whether to issue a prompt signal for reminding the user to take out or add water;

[0077] Specifically, if the water tank 112 assembly status remains unchanged within a preset time T, the prompt signal is issued until the water tank 112 is detected to be not fully assembled. If the water tank 112 assembly status changes within the preset time T, the food processor continues to operate without issuing the prompt signal. T can be 5 seconds, 10 seconds, or other values, and this embodiment does not limit the specific value of the preset time T. Simply put, since the user must remove the water tank 112 from the main unit 100 to access or drain the water, this embodiment determines whether the user has accessed or drained the water tank 112 by determining whether the water tank 112 signal changes within the preset time T. In other words, if the water tank 112 signal changes within the preset time T, it is assumed that the user has removed the water tank 112 and performed the water access operation. If the water tank 112 signal does not change within the preset time T, it is assumed that the user forgot to remove the water tank 112 and did not perform the water access operation. In this case, the machine issues a prompt signal to prompt the user to access or drain the water.

[0078] However, it should be noted that after the preset time T is exceeded, the main control chip continues to control the machine to execute subsequent processing steps regardless of whether a change in the signal from the water tank 112 is detected.

[0079] In this embodiment, the material detection stage and the water quantity detection stage can determine and identify the weight of the material and water placed by the user in the machine. Based on the different states of the machine and in conjunction with corresponding detection logic, accurate detection of the material and water quantities can be achieved. Furthermore, when the material quantity or amount does not match, the user can be prompted to take appropriate placement actions to adjust and control the material and water quantities. This ensures that the machine can achieve good pulping results under all conditions, reduces the risk of pulp overflow and pulping noise, improves the material crushing effect and motor life, and greatly improves the user experience.

[0080] After the above steps of material weighing, material testing, water weighing, and water testing, the machine can clearly obtain the weight of the material and the weight of the water. Therefore, the machine can continue to perform the pulping water quantity calculation step based on the calculated material weight and water weight.

[0081] Specifically, in the pulping water volume calculation stage, the main control chip can calculate the pulping water volume M according to the weight of the material and the preset pulping parameters. 水_制 The pulping parameters include the minimum pulping material weight M 物min and the corresponding pulping water volume M 水_物min , and the proportional coefficient K, then M 水_制 =K*(M 物 / M 物min )*M水_物min Among them, it should be noted that the pulping water volume M 水_制 Should be lower than the water volume M in the water tank 112 水 , that is, M 水_制 ≤M 水 .

[0082] Furthermore, after the pulping water amount calculation stage, the weighing method may further include:

[0083] Pulping amount detection stage: the main control chip detects the pulping amount M according to the preset threshold ΔM and the pulping water amount M 水_制 Judgment function pulping amount M 制 Is it within the preset third range? If so, the main control chip controls the food processor to make pulp according to the function M 制 Perform pulping operation; if not, the main control chip reminds the user to take out or add part of the material; or the main control chip controls the food processor to make pulp according to the function corresponding to the weight of the material M 制 Perform pulping operation.

[0084] Specifically, it can be assumed that the third range is [M 水_制 -△M,M 水_制 +△M]. Wherein, △M is preferably 300ml. It should be understood that △M in this embodiment should be determined according to the specific capacity of the mixing cup in the machine and the design requirements of the product, etc., and this application does not limit this. Then:

[0085] When M 制 ≤M 水_制 -△M, it can be considered that the user has placed too much material, and the machine prompts the user to take out some of the material or select the function pulping amount M corresponding to the material weight. 制 Perform pulping operation.

[0086] When M 水_制 -△M <M 制 <M 水_制 When +△M, the machine performs pulping operation according to the actual functional pulping amount.

[0087] When M 制 ≥M 水_制 +△M, it can be considered that the material placed by the user is too little, and the machine prompts the user to add some material or select the function pulping amount M corresponding to the material weight. 制 Perform pulping operation.

[0088] The main control chip in this embodiment can calculate the amount of pulping water required during the actual pulping process based on the weight of the material and the pulping parameters. Then, during the pulping amount detection phase, the main control chip determines whether to continue the pulping operation by judging the functional pulping amount. This setting method allows the machine to match the corresponding pulping water amount and pulping amount according to the size of the material, thereby reducing the risk of pulp overflow during the pulping process, increasing the life of the motor, reducing pulping noise, improving the user experience, and increasing the intelligence of the machine. It also helps to improve the material crushing effect and improve the taste of the pulp, thereby improving the pulping effect of the machine.

[0089] Furthermore, it should be noted that during the actual pulping process, the pulping water needs to be divided into multiple inflows as it enters the mixing cup, allowing for sufficient mixing of the material and water in the mixing cup, thereby improving the pulping effect of the machine. Furthermore, considering the appearance and overall integrity of the machine, after the water tank 112 is placed, the fixed components of the machine are integrated with the water tank 112. During the water inflow process, the main control chip cannot identify the amount of water entering through the weighing sensor. Therefore, the food processing machine provided in this application can monitor the amount of pulping water by providing a flow meter on the main unit 100.

[0090] It should be understood that in order to accurately monitor the water intake of the machine, in addition to setting a flow meter, this embodiment can also monitor the pulping water volume by setting a driving water pump on the host 100 to drive the pulping water volume, and allowing the main control chip to measure the driving time of the driving water pump. Specifically, a specific water intake volume M can be preset for the main control chip. 水Q , and the water inflow time T corresponding to the water inflow 水Q Thus, in the normal pulping process, the pulping water intake M 水n The corresponding water inflow time is T 水n =(M 水n / M 水Q )*T 水Q , the machine only needs to control the water inlet time of the driving water pump to monitor the amount of pulping water.

[0091] To ensure the weighing accuracy of the machine, the food processor provided in this application needs to be calibrated with the weighing sensor or other related accessories before leaving the factory. For example, the detachable component 110 can be removed first, and then after the machine is powered on, a combination of buttons can be pressed to put the machine into calibration mode. For specific calibration operations, please refer to the following instructions:

[0092] First, place the calibration module on the machine for weighing. If the test result is within the error range, the weighing sensor is considered normal. If the test result is outside the error range, the calibration deviation is entered through the operation interface to complete the calibration. Next, remove the calibration module and the machine obtains the weight M of the fixed component. 固 Then, place the cover 111 again and get the weight M. 上 Stored in the main control chip; further, place the empty water tank 112 and obtain the weight M 箱 Stored in the main control chip; finally, the machine is powered on again and the calibration before leaving the factory is completed.

[0093] Due to issues such as deviations in the assembly of the load cells and the accuracy and quality of the load cells themselves, a calibration module is required to calibrate them to ensure the accuracy of the load cell measurements and the reliability of the machine, thereby improving the user experience. Furthermore, the fixed and detachable components 110 of the machine differ in weight. By weighing and identifying the relevant components and storing them in the system, the user can accurately detect the amount of material and water placed during use, avoiding misjudgments. Furthermore, this embodiment uses a combination of buttons to enter calibration mode, which can largely prevent users from accidentally entering the calibration mode during operation, thereby maintaining the stability of the machine.

[0094] To sum up, the weighing method of the food processing machine provided in the present application, since the main machine has a weighing function, can weigh and measure the materials, water, detachable parts and fixed parts placed on the main machine, so that the user can grasp the correspondence between the material quantity and the pulping water quantity during the pulping process, and achieve a perfect match between the material quantity and the pulping water quantity, avoiding problems such as reduced motor life, slurry overflow, poor material crushing, loud pulping noise, insufficient slurry concentration affecting taste, and secondary water addition caused by placing too much or too little material, thereby greatly improving the pulping effect of the machine and the user experience, making the machine more humane and intelligent.

[0095] In one embodiment, the food processor provided in the present application may further include a memory, a processor, and execution instructions stored in the memory and running on the processor, wherein when the execution instructions are executed by the processor, the food processor can perform the weighing method described above.
