Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a steam-heated food processor and a pulping method of the steam-heated food processor. Background Art

[0002] Food processors often use heating tubes, electromagnetic heating, steam heating and other methods to process food. Among them, steam-heated food processors do not cause tube sticking problems and can meet the heating requirements of different cooking methods. It is a more advanced heating technology. However, during the steam heating process, the steam will condense into water and mix in the slurry, increasing the amount of water in the slurry, causing the slurry to turn white, affecting the concentration and uniformity of the slurry, and reducing the taste and quality of the finished slurry.

[0003] Therefore, in the process of food processing, in order to shorten the steam heating process and ensure that the slurry temperature is sufficient to prevent the problem of undercooked slurry, some manufacturers will add heating tubes to compensate for the slurry heating. In addition, some food processors will also use high-speed motors to grind the ingredients to improve the fineness of the grinding.

[0004] However, the method of compensating heating through heating pipes is costly, the installation structure is complex, and there is a risk of pipe sticking, which will lose the advantage of steam heating. In addition, although high-speed motors have high speeds and better crushing effects, they have high motor power, high energy consumption, and high heat generation, which can easily cause slurry overflow during the pulping process. Summary of the invention

[0005] In order to solve the above problems, the present application provides a steam-heated food processor and a pulping method for a steam-heated food processor, which can assist in heating the slurry through the heat generated by the motor-driven blades. It has a simple structure and low cost, and can control the motor speed in real time according to the slurry temperature. It is beneficial to reduce energy consumption while ensuring the doneness of the ingredients.

[0006] To achieve the above-mentioned purpose, on the one hand, the present application proposes a pulping method of a steam-heated food processor, the steam-heated food processor comprising a cup body, a blade, a motor, a steam heating device, and a temperature sensor, the blade being arranged in the cup body, and the motor driving the blade to rotate to crush or stir food, comprising:

[0007] Steam heating stage: controlling the steam heating device to steam heat the food in the cup;

[0008] In the steam heating stage, the rotation speed of the motor is adjusted, and the motor drives the blade to rotate to increase the temperature of water generated by steam condensation during the steam heating process.

[0009] In one example, according to the temperature of the slurry in the cup, the rotation speed of the motor is adjusted, specifically including: adjusting the rotation speed of the motor to be negatively correlated with the temperature of the slurry in the cup.

[0010] In one example, according to the temperature of the slurry in the cup, the rotation speed of the motor is adjusted, specifically including: when the temperature of the slurry in the cup is less than or equal to T0, adjusting the motor rotation speed to N1 for auxiliary heating; when the temperature of the slurry in the cup is greater than T0, adjusting the motor rotation speed to N2 for auxiliary heating; where T0, N1, and N2 are preset parameter values, and N1 > N2.

[0011] In one example, before adjusting the motor rotation speed to N2 for auxiliary heating, the method further includes: determining that the temperature of the slurry in the cup is not greater than T1; where T0 < T1; according to the temperature of the slurry in the cup, the rotation speed of the motor is adjusted, specifically further including: when the temperature of the slurry in the cup is greater than T1, adjusting the motor rotation speed to N3 for heat preservation; where N1 > N2 > N3.

[0012] In one example, the method further includes: when the temperature of the slurry in the cup is greater than T1 + 1°C, controlling the motor to stop working; when the temperature of the slurry in the cup is greater than T0 and less than T1, controlling the motor to resume working at the rotation speed N2.

[0013] In one example, the method further includes: when it is determined that the running time corresponding to the motor running at the rotation speed N2 reaches t1, or when it is determined that the running time corresponding to the motor running at the rotation speed N3 reaches t2, or when it is determined that the total running time corresponding to the motor running at the rotation speeds N1, N2, and N3 reaches t3, controlling the motor to stop working; where t3 > t1 > t2.

[0014] In one example, before controlling the steam heating device to perform steam heating on the ingredients in the cup, the method further includes: controlling the motor to perform pre - grinding on the ingredients; determining the weight of the ingredients according to the current of the motor in the pre - grinding stage; determining the grinding time for the ingredients according to the weight of the ingredients, and grinding the ingredients according to the grinding time; where the weight of the ingredients is positively correlated with the grinding time.

[0015] In one example, the N1 is 15000 RPM to 17000 RPM.

[0016] In one example, the method further includes: in the steam heating stage, while adding steam to the cup, starting the motor.

[0017] On the other hand, the present application also proposes a steam - heated food processor, and the steam - heated food processor includes:

[0018] Cup body;

[0019] A host connected to the cup body;

[0020] A motor, wherein the motor is arranged in the main machine, a motor shaft of the motor extends into the cup body, a blade is arranged on one side of the motor shaft extending into the cup body, and the motor drives the blade to rotate through the motor shaft;

[0021] A motor bracket is arranged at an opening at one end of the cup body connected to the main machine, and the motor shaft passes through the motor bracket; wherein the motor bracket and the motor shaft are both made of metal materials so that the heat of the motor can be transferred to the slurry through the motor shaft and the motor bracket.

[0022] The steam-heated food processor and the pulping method of the steam-heated food processor proposed in the present application at least have the following beneficial effects:

[0023] 1. During the steam heating stage, determine the motor speed that is appropriate for the current situation, so that the motor speed can be changed flexibly, and always provide appropriate auxiliary heating and temperature rise for the slurry to eliminate the water generated by steam condensation during the heating stage, give full play to the role of motor auxiliary heating, and avoid condensed water mixed into the slurry and stratification and whitening, so that the slurry has a uniform texture, better concentration and taste. Promote the pulping process of the food processor, and maximize the pulping efficiency and shorten the pulping time while ensuring that the slurry is cooked to a qualified degree.

[0024] 2. Based on the detection of slurry temperature, the motor speed can be controlled in real time and adjusted reasonably to avoid the problem of slurry overflow caused by excessive motor speed when the slurry temperature is high, and to avoid the problem of insufficient heat for the slurry caused by too low motor speed when the slurry temperature is low.

[0025] 3. The heat generated by the motor itself and the heat generated by the friction between the motor-driven blade and the food can be used to assist in heating the slurry, thus realizing energy recycling and being beneficial to energy saving and consumption reduction. No additional auxiliary heating device is required, the structure is simple, the cost is low, and it is beneficial to product promotion.

[0026] 4. By controlling the motor speed and reasonably adjusting the motor speed, the motor can be prevented from running continuously at a high speed, which may damage the motor. At the same time, the energy consumption of the food processor can be reduced, thus achieving the goal of energy saving and consumption reduction.

[0027] 5. By setting several fixed motor speed values, frequent adjustment of the motor speed can be avoided, which may cause damage to the motor, and is conducive to extending the service life of the motor.

[0028] 6. By setting preset conditions and controlling the motor to stop working in time, it can prevent the motor from working too long and causing damage to the motor, thus extending the service life of the motor.

[0029] 7. Anti-stick coating is applied on the motor bracket and the motor shaft to avoid slurry adhesion during heating and eliminate the risk of pipe sticking.

[0030] 8. Set the thermal equilibrium state of the slurry temperature. By adjusting the speed of the motor, the prepared slurry is always kept at an appropriate temperature. While reducing the energy consumption of the motor, it avoids the slurry temperature being too low and the slurry temperature being too high, which causes boiling and overflowing, so that the user can drink it later.

[0031] 9. Automatically adjust the full-force crushing time required for ingredients during the crushing and boiling stage to ensure that the ingredients have sufficient time to be crushed and the crushing degree of the ingredients is guaranteed, avoiding the subsequent rapid rise in slurry temperature, which leads to a shortening of the motor working time and has an adverse effect on the crushing degree of the ingredients.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0042] For the convenience of description, the "front", "back", "left", "right", "up" and "down" in the following text refer to the directions relative to the user when the steam heating food processor is in use.

[0043] Figure 1 This is a schematic structural diagram of a steam-heated food processor provided in an embodiment of the present application.

[0044] like Figure 1 As shown, the food processor mainly includes a cup body 1, a main unit 2, a motor 3, a motor bracket 31, a motor shaft 32, and a blade 33. Specifically, the upper and lower ends of the cup body 1 are respectively provided with openings, the upper opening is used to put food into the cavity of the cup body, and one end of the lower opening is connected to the main unit 2; a motor bracket 31 is provided at the lower opening of the cup body 1; the motor 3 is arranged in the main unit 2, and the motor shaft 32 of the motor 3 passes through the motor bracket 31 and extends into the cup body 1; a blade 33 is provided on the side where the motor shaft 32 extends into the cup body 1, and the motor 3 drives the blade 33 to rotate through the motor shaft 32 to crush the food. Among them, the motor bracket 31 and the motor shaft 32 are both made of metal materials, so that the heat of the motor 3 can be transferred to the slurry through the motor shaft 32 and the motor bracket 31 to assist in heating the slurry.

[0045] The steam-heated food processor can assist in heating the slurry by using the heat generated by the motor itself and the heat generated by the friction between the motor-driven blade and the food. This method realizes the recycling of energy and is conducive to energy saving and consumption reduction.

[0046] Furthermore, the food processor does not need to be equipped with an additional auxiliary heating device, has no complicated structure, is relatively simple to implement, and has a low cost, which is conducive to product promotion.

[0047] In one embodiment, the motor bracket and the motor shaft may be made of metal aluminum. Aluminum has good thermal conductivity and facilitates heat conduction.

[0048] In one embodiment, the upper surface of the motor bracket and the outer surface of the portion of the motor shaft extending into the cup body are provided with an anti-stick coating. Since the upper surface of the motor bracket and the outer surface of the portion of the motor shaft extending into the cup body can directly contact the slurry, the provision of the anti-stick coating can prevent the slurry from adhering to the motor bracket and the motor shaft during the heating process.

[0049] The steam heating food processor comprises three stages during its working process: a preheating stage, a pre-crushing stage and a crushing and boiling stage.

[0050] In the preheating stage, the food processor quickly heats the food and the slurry through high-temperature steam, and heats the slurry to a fixed temperature.

[0051] In the pre-crushing stage, the food processor controls the motor to work at a low speed to perform preliminary crushing of the food materials to reduce the crushing noise in the subsequent crushing and boiling stages.

[0052] In the crushing and boiling stage, the food processor heats the ingredients through high-temperature steam. Figure 2As shown, the food processor controls the motor to first run at full speed to crush the food materials to ensure that the degree of crushing of the food materials meets the requirements. After that, the speed of the motor is adjusted according to the real-time slurry temperature. The motor drives the blade to rotate to heat the water generated by steam condensation during the steam heating process, eliminate the condensed water generated during the steam heating process, avoid reducing the slurry concentration and the slurry turning white and stratifying, so that the produced slurry has a mellow taste, rich fragrance and delicious taste.

[0053] and Figure 1 Corresponding to the steam-heated food processor shown, the present application also provides a pulping method for a steam-heated food processor.

[0054] Figure 3 The flow chart of the pulping method of the steam-heated food processor provided in the embodiment of the present application specifically includes the following steps:

[0055] S301: In the steam heating stage, the steam heating device is controlled to steam heat the food in the cup.

[0056] The steam heating food processor includes a cup body, a blade, a motor, a steam heating device and a temperature sensor. The cup body is used to hold food and slurry, the steam heating device is used to steam heat the food in the cup body, the motor is used to drive the blade to rotate and crush the food, and the temperature sensor is used to sense the temperature of the slurry in the cup body.

[0057] In the steam heating stage, the steam heating food processor can use steam to steam heat the food in the cup body by controlling the steam heating device based on the control of the user. It should be noted that the "steam heating stage" mentioned in the embodiments of the present application is included in the crushing and boiling stage of the steam heating food processor, and the following descriptions, unless otherwise specified, are all related descriptions of the crushing and boiling stage.

[0058] S302: In the steam heating stage, the speed of the motor is adjusted according to the temperature of the slurry in the cup body, so as to utilize the heat generated by the motor-driven blade rotation for auxiliary heating.

[0059] In the embodiment of the present application, the steam-heated food processor can obtain the temperature of the slurry in the cup body in real time through the temperature sensor during the steam heating stage. Afterwards, the steam-heated food processor can adjust the speed of the motor in real time according to the slurry temperature, so as to assist in heating the slurry through the heat generated by the rotation of the blade driven by the motor.

[0060] Through this method, the heat generated by the motor body and the heat generated by the high-speed friction between the blade and the food can be used to auxiliary heat the slurry, realize the secondary utilization of energy, and achieve the purpose of energy saving and consumption reduction.

[0061] Compared with the method of compensatory heating through heating pipes in the prior art, this method can provide supplementary heat for the slurry to ensure that the slurry temperature is sufficient. At the same time, this method does not have the risk of pipe sticking and can form a good combination with steam heating.

[0062] Furthermore, the auxiliary heating achieved by the method does not require the addition of an additional auxiliary heating device, has a simple structure and low cost.

[0063] In addition, the method can control the motor speed in real time based on the detection of the slurry temperature, so as to reasonably adjust the motor speed according to the slurry temperature, to avoid the problem that the motor speed is too high when the slurry temperature is high, which easily leads to slurry overflow, and to avoid the problem that the motor speed is too low when the slurry temperature is low, which cannot provide sufficient heat for the slurry.

[0064] In addition, by controlling the motor speed and reasonably adjusting the motor speed, the motor can be prevented from continuously running at a high speed, which can reduce the energy consumption of the food processor and achieve the purpose of energy saving and consumption reduction.

[0065] In one embodiment, when the steam-heated food processor adjusts the speed of the motor according to the temperature of the slurry in the cup body, the speed of the motor can be adjusted to be in a negative correlation with the temperature of the slurry in the cup body. That is, the higher the slurry temperature, the lower the speed of the motor should be, and the lower the slurry temperature, the higher the speed of the motor should be.

[0066] When the slurry temperature is high, the motor does not need to provide too much auxiliary heat for the slurry, and too high a speed can easily cause the slurry to boil and overflow. Therefore, the motor speed should be lower at this time to prevent the slurry from splashing and overflowing.

[0067] When the slurry temperature is low, the motor needs to be rotated at a high speed to provide more auxiliary heat to ensure that the slurry has enough heat and reaches a sufficient temperature, so that the slurry will not be undercooked. Therefore, the motor speed should be high at this time.

[0068] By establishing the negative correlation between the motor speed and the slurry temperature, the corresponding motor speed suitable for the current situation can be reasonably determined according to the slurry temperature, so that the motor speed can be flexibly changed, and the appropriate auxiliary heating can always be provided for the slurry, giving full play to the role of motor auxiliary heating.

[0069] At the same time, properly adjusting the motor speed can prevent the motor from continuously running at a high speed, which would result in greater energy consumption.

[0070] In one embodiment, the steam-heated food processor can divide the slurry temperature into different ranges, and determine the appropriate speed of the corresponding motor according to the different slurry temperatures, so as to accurately adjust the speed of the motor.

[0071] In one possible implementation, Figure 2 As shown, according to the slurry temperature, the method of adjusting the motor speed can be specifically:

[0072] When the slurry temperature in the cup is less than or equal to T0, the motor speed is adjusted to N1 for auxiliary heating; at this time, the slurry temperature is low. In order to provide more heat to the slurry and promote its temperature rise, the motor speed should be higher, thereby obtaining a larger auxiliary heating power, providing a larger auxiliary heating effect on the slurry, and accelerating the increase of the slurry temperature;

[0073] When the slurry temperature in the cup body is greater than T0, the motor speed is adjusted to N2 for auxiliary heating; at this time, the slurry temperature is relatively high and the motor does not need to provide too much auxiliary heating. Therefore, the motor can be controlled to run at a relatively low speed to obtain a smaller auxiliary heating power. This can also avoid situations such as overflow of the slurry due to thermal inertia caused by excessive motor speed at high temperatures.

[0074] Among them, T0, N1, and N2 are preset parameter values, and N1>N2, which can be set specifically according to needs, and this application does not limit this.

[0075] It can be seen that this method divides the slurry temperature according to the temperature T0, and determines the motor speed corresponding to the slurry temperature in each temperature range, so that the motor speed can be accurately adjusted.

[0076] Furthermore, through this method, appropriate auxiliary heating can be provided for the slurry according to different slurry temperatures to promote the slurry making process of the food processor, and the slurry making efficiency can be improved as much as possible and the slurry making time can be shortened while ensuring that the slurry is cooked to a qualified degree.

[0077] In addition, by setting two motor speed values, frequent adjustment of the motor speed can be avoided, which may cause damage to the motor, and is beneficial to extending the service life of the motor.

[0078] In one embodiment, when the slurry is cooked to a qualified degree, the slurry temperature is sufficient, and at this moment, the motor does not need to provide auxiliary heating. Thus, in this case, the steam-heated food processor can adjust the speed of the motor according to the preset slurry cooked temperature.

[0079] In a possible implementation, the cooking temperature of the slurry may be T1, and a certain temperature range where this temperature is located may be regarded as a thermal equilibrium state of the slurry, that is, a heat preservation state.

[0080] If the slurry temperature in the cup is not greater than T1, it means that the slurry is not cooked and the motor needs to continue to provide auxiliary heating. Therefore, the steam heating food processor can adjust the motor speed for auxiliary heating according to the real-time collected slurry temperature.

[0081] If the slurry temperature in the cup is greater than T1, Figure 2 As shown, it means that the slurry temperature is sufficient and the slurry is cooked to the required degree, that is, the slurry has been made. At this time, the slurry no longer needs too much auxiliary heating, so the steam heating food processor can adjust the motor speed to N3 to keep the slurry warm. At this time, the auxiliary heating effect of the motor is small, and its auxiliary heating power is consistent with the heat dissipation power, which is mainly used to maintain the slurry temperature in a thermal equilibrium state.

[0082] Among them, T0<T1,N1> N2>N3, T1 and N3 can be set specifically according to needs, and this application does not limit this.

[0083] After the slurry is cooked to a satisfactory degree, the motor speed can be adjusted to a lower value to avoid wasting energy on the motor and to keep the slurry warm by using the less heat generated by the motor. In addition, reducing the motor speed can prevent the slurry from overflowing due to the high-speed rotation of the blade, which is conducive to the good preservation of the slurry.

[0084] In one embodiment, N1 is 15000 RPM (Revolutions Per minute, RPM) to 17000 RPM, N2 is 12000 RPM to 14000 RPM, and N3 is 8000 RPM to 10000 RPM. It can be seen that compared with the existing food processors that stir at a low speed during the boiling stage, the motor speed of the steam-heated food processor in the crushing and boiling stage is automatically adjusted according to the slurry temperature.

[0085] In one embodiment, the thermal equilibrium state of the slurry may be T1~T1+1°C. When the slurry temperature is within this temperature range, it indicates that the slurry is in a thermal equilibrium state.

[0086] Therefore, when the steam-heated food processor collects the slurry temperature in real time, if it is determined that the slurry temperature is greater than T1+1°C, it means that the slurry temperature is too high. At this time, the steam-heated food processor can control the motor to stop working and terminate the auxiliary heating function of the motor, so that the slurry temperature drops to below T1+1°C and returns to a thermal equilibrium state.

[0087] In addition, if the temperature of the slurry in the cup body drops from T1 to T0~T1, it means that the slurry temperature is out of thermal equilibrium and the temperature is low. Therefore, the steam heating food processor can adjust the motor to resume operation at a speed of N2 to provide auxiliary heating to the slurry to increase the slurry temperature.

[0088] Similarly, if the slurry temperature in the cup body is less than T0, it also means that the slurry temperature is too low. At this time, the motor can be adjusted to perform auxiliary heating at a speed of N1 to increase the slurry temperature.

[0089] By setting the thermal equilibrium state of the slurry temperature, the motor speed can be continuously adjusted according to the real-time detected slurry temperature, so that the prepared slurry is always maintained at an appropriate temperature, avoiding low slurry temperature and avoiding excessive slurry temperature causing boiling and overflow, so that the user can drink it later.

[0090] In one embodiment, if the food material is sufficiently crushed and the slurry is cooked to a satisfactory degree, the motor may be controlled to stop working according to preset conditions in order to avoid the motor running for too long and causing damage to the motor.

[0091] In one possible implementation, Figure 4 As shown, the preset conditions may include:

[0092] First, the motor runs at a speed of N2 for a corresponding running time of t1, that is, the slurry temperature is continuously maintained above T0, and the maintenance time reaches t1;

[0093] Second, the motor runs at a speed of N3 for a corresponding running time of t2, that is, the slurry temperature is maintained above T1 and the maintenance time reaches t2;

[0094] Third, the total running time corresponding to the motor running at speeds N1, N2, and N3 reaches t3;

[0095] If the operation of the motor meets any of the above three conditions, it means that the cookedness of the slurry is qualified and the running time of the motor has reached the standard, and the motor can be controlled to stop working. Among them, t3>t1>t2, the specific values ​​of t1, t2, and t3 can be set as needed, and this application does not limit this.

[0096] Among them, in the third case, the motor has a long cumulative total running time, but the slurry temperature does not meet the standard. This may be due to the failure of the temperature sensor and other reasons, resulting in inaccurate temperature measurement data. In this case, since the motor has been running for a long enough time, it can be considered that the actual slurry temperature has met the requirements, and the motor can be stopped.

[0097] By setting preset conditions and controlling the motor to stop working in time, the motor can be prevented from working too long and causing damage to the motor, thereby extending the motor's service life. In addition, this can also reduce the energy consumption of the motor's continuous operation, reduce the energy consumption of the entire machine, and achieve energy conservation and emission reduction.

[0098] In one embodiment, T0 is 3-5°C below the boiling point, and T1 is 0-2°C below the boiling point.

[0099] Correspondingly, since T0 is the lowest temperature of the slurry, t1 can be 120~240 seconds to ensure that the slurry has enough time to heat up. Since T1 is close to the boiling point, t2 can be 60~100 seconds, which can ensure that the slurry has a qualified degree of doneness in a shorter time.

[0100] In one embodiment, when the steam-heated food processor is crushing and boiling food, the weight of the food can be determined according to the current of the motor in the pre-crushing stage, and the time required for the motor to run at full speed and crush the food in the early stage of the crushing and boiling stage can be determined accordingly. The weight of the food is positively correlated with the required full-power crushing time, and the relationship can be linear. The heavier the weight of the food, the more full-power crushing time is required.

[0101] By determining the weight of the ingredients based on the current of the motor in the pre-crushing stage and automatically adjusting the full-force crushing time required for the ingredients in the crushing and boiling stage, it can be ensured that the ingredients have sufficient time to be crushed and the crushing degree of the ingredients is guaranteed, thereby avoiding the subsequent adverse effects on the crushing degree of the ingredients due to the rapid rise in slurry temperature, which leads to a shortening of the motor working time.

[0102] In one embodiment, the steam-heated food processor may include a storage module, in which the corresponding relationship between the motor current and the weight of the food in the pre-crushing stage is stored. Thus, the steam-heated food processor can obtain the corresponding weight of the food according to the motor current in the pre-crushing stage.

[0103] In one embodiment, the crushing time when the motor operates at full speed is 200-300 seconds.

[0104] In one embodiment, the steam heating device is started under the control of the user to deliver steam into the cup body. While performing steam heating, the steam heating food processor also controls the motor to drive the blade to rotate for auxiliary heating.

[0105] In one embodiment, Figure 5 As shown, the steam heating food processor can adjust the steam heating power of the steam heating device in real time according to the change of the slurry temperature. Among them, the steam heating power is negatively correlated with the slurry temperature. The higher the slurry temperature, the smaller the steam heating power.

[0106] Correspondingly, the steam-heated food processor can also be divided into slurry temperatures according to T0 and T1.

[0107] If the slurry temperature is less than or equal to T0, the steam heating device can be controlled to operate at power P1, if the slurry temperature is greater than T0 and less than or equal to T1, the steam heating device can be controlled to operate at power P2, and if the slurry temperature is greater than T1, the steam heating device can be controlled to operate at power P3. Among them, P1>P2>P3, P1, P2, P3 can be specifically set as needed, and this application does not limit this.

[0108] By adjusting the steam heating power of the steam heating device in real time according to the change of the slurry temperature, the slurry temperature can be increased by using a larger power when the slurry temperature is low, and the thermal equilibrium state of the slurry temperature can be maintained by using a smaller power when the slurry temperature is high.

[0109] This can flexibly adjust the changes in steam heating power, reduce the energy consumption of the steam heating device, reduce the energy consumption of the entire machine, and achieve energy conservation and emission reduction.

[0110] In addition, if Figure 5 As shown, the steam heating food processor can also determine the steam heating time of the steam heating device according to the pulping amount specified by the user, that is, t4. Among them, the pulping amount is positively correlated with the steam heating time.

[0111] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments.
