[0107] This application provides a control method and a cooking machine for a cooking machine. The control method and the cooking machine of this application will be described in detail below with reference to the drawings. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0108] Figure 1 Shown is a schematic structural diagram of an embodiment of the cooking machine 10 of this application.

[0109] AsFigure 1 As shown, the cooking machine 10 includes a cooking cup assembly 11 and a control device 12.

[0110] The cooking cup assembly 11 is used to hold ingredients, which can be used for cooking and made into slurry. The control device 12 is used to control the cooking machine 10 to cook the ingredients. In Figure 1 In the illustrated embodiment, the control device 12 is assembled inside the cooking cup assembly 11.

The water tank 16 is used to hold water, the slurry receiving cup 17 is used to hold the completed slurry, and the waste water recovery container 171 is used to receive the waste water generated during the cooking process. When cooking the ingredients, after the ingredients are placed in the cooking cup assembly 11, the water in the water tank 16 is injected into the cooking cup assembly 11, and operations such as heating, whipping, and crushing are performed on the ingredients. The ingredients are made into slurry. After completion, the slurry flows into the slurry receiving cup 17, and the waste water flows into the waste water recovery container 171. Figure 1 The cooking machine shown is only an exemplary embodiment, and this application is not limited to Figure 1 the cooking machine shown and can be other types of cooking machines.

[0111] Figure 2 Shown is a schematic structural diagram of another embodiment of the cooking machine 10 of this application.

[0112] The cooking cup assembly 11 includes a cooking cup 13, a heat exchange cavity 14 provided outside the side wall of the cooking cup 13, and a coolant injection assembly 15 connected to the heat exchange cavity 14. The control device 12 is electrically connected to the coolant injection assembly 15 and is used to execute the control method of the cooking machine provided in this application.

[0113] The cooking cup 13 is used to hold ingredients. The coolant injection assembly 15 is used to store coolant and inject the coolant into the heat exchange cavity 14. The heat exchange cavity 14 is used to allow the coolant to flow, so that the coolant exchanges heat with the slurry in the cooking cup 13 and reduces the temperature of the slurry.

[0114] In some embodiments, the material of the cooking cup 13 is one of copper, aluminum, stainless steel, and glass.

[0115] In some embodiments, the material of the heat exchange cavity 14 is one of copper, aluminum, stainless steel, and glass.

[0116] In some embodiments, the thickness of the wall of the cooking cup 13 is h, where 0.1 mm ≤ h ≤ 16 mm.

[0117] The higher the thermal conductivity of the materials of the cooking cup 13 and the heat exchange cavity 14, and the thinner the wall of the cooking cup 13, the faster the slurry cools down.

[0118] The coolant injection assembly 15 includes a liquid storage tank 151 and a driving device 152. The liquid storage tank 151 is used to store coolant. The coolant can be water, phase change coolant, oil, etc. When the coolant is water, the liquid storage tank 151 can be a water tank 16. The driving device 152 is used to drive the coolant stored in the liquid storage tank 151 to the heat exchange cavity 14. The driving device 152 includes a water pump. Figure 2 The line segment A in it represents the flow direction of the coolant. The coolant exchanges heat with the slurry in the cooking cup 13 in the heat exchange cavity 14, and then flows out of the heat exchange cavity 14 and back to the liquid storage tank 151, so as to circulate.

[0119] The cooking machine 10 further includes a heating assembly 18, a stirring knife assembly 19, and an exhaust system 131.

The cooking machine 10 further includes a motor drivingly connected to the stirring knife assembly 19 for driving the stirring knife assembly 19 to work. The exhaust system 131 can blow air into the cooking cup 13 to reduce the temperature of the slurry in the cooking cup 13. The exhaust system 131 can be arranged at the top of the cooking cup 13.

[0120] Figure 3 The figure shows a flowchart of an embodiment of the control method 20 of the cooking machine of the present application.

[0121] The control method 20 of the cooking machine includes: step 21 to step 23.

[0122] Step 21, control the cooking machine 10 to make slurry.

[0123] When making the slurry, solid ingredients are put into the cooking cup 13, and water is injected from the water tank 16. In some other embodiments, solid ingredients and water are put into the cooking cup 13 by the user. According to the cooking function selected by the user, slurry making can be juice, soy milk, milkshake, etc. The slurry making process can include a heating stage, a boiling stage, a crushing stage, etc.

[0124] Step 22, after the slurry making is completed, determine the flow rate of the coolant according to the desired temperature of the slurry, the finished product temperature when the slurry making is completed, and the slurry quality of the slurry.

[0125] After the slurry is made, its finished product temperature, i.e., the real-time temperature of the slurry at the moment of completion of production, is usually relatively high, and the slurry needs to be cooled down to meet the drinking requirements of users. The desired temperature is the temperature that the slurry is expected to reach, which is usually lower than the finished product temperature. The quality of the slurry affects the amount of heat released required for slurry cooling. The flow rate of the coolant, i.e., the flow rate of the coolant in the heat exchange cavity 14. For slurries that require the same amount of heat release, the greater the flow rate of the coolant, the faster the coolant flows, the faster the heat is released, and the faster the slurry cools down. The lower the desired temperature, the higher the finished product temperature, and the greater the slurry quality, the greater the flow rate should be. A mathematical model or corresponding relationship table between the desired temperature, finished product temperature, slurry quality, and flow rate can be established in advance through experiments. Substituting the desired temperature, finished product temperature, and slurry quality into this mathematical model or corresponding relationship table can directly obtain the flow rate. Through the desired temperature, finished product temperature, and slurry quality, the appropriate flow rate of the coolant can be determined so that the slurry can be cooled down within a reasonable time.

[0126] In some embodiments, step 22 includes: determining the flow rate of the coolant according to the desired temperature, finished product temperature, slurry quality, and specific heat capacity of the coolant. In this way, the flow rate of the coolant can be determined more accurately.

[0127] In some embodiments, before step 22, the control method 20 further includes: obtaining the desired temperature input by the user. Determining the flow rate of the coolant according to the desired temperature input by the user, so as to cool down the slurry, can make the slurry more meet the user's needs. The cooking machine 10 includes a control panel for interacting with the user, and the user can input the desired temperature through the control panel.

[0128] Step 23, control the coolant injection component 15 to make the coolant flow in the heat exchange cavity 14 at the flow rate until the temperature of the slurry drops to the desired temperature.

[0129] The control device 12 controls the driving device 152 to pump the coolant out of the liquid storage tank 151 at the flow rate determined in step 22, send it into the heat exchange cavity 14, and make the coolant circulate in the heat exchange cavity 14 at this flow rate to exchange heat with the slurry in the cooking cup 13 and reduce the temperature of the slurry. The cooking machine 10 includes a temperature measuring element for measuring the temperature of the slurry. During the process of the coolant circulating and flowing, continuously monitor the temperature of the slurry. When the temperature of the slurry reaches the desired temperature, control the coolant to stop flowing, and the slurry cooling is completed. The cooled slurry flows into the receiving cup 17, so that the user can obtain the slurry at the desired temperature.

[0130] In some embodiments, by determining the flow rate of the coolant according to the desired temperature of the slurry, the finished product temperature when the slurry is made, and the quality of the slurry, and according to the specific conditions of the current slurry, the corresponding flow rate of the coolant is determined, and the coolant injection assembly 15 is controlled to make the coolant flow in the heat exchange cavity 14 at this flow rate, so that the coolant exchanges heat with the slurry, so that for different slurries, the temperature of the slurry can be quickly reduced to the desired temperature according to the user's needs, avoiding the slurry temperature being too high and being unfavorable for the user to directly drink, making the slurry temperature more in line with the user's needs.

[0131] In some embodiments, the control method 20 further includes: determining the specific heat capacity of the slurry according to the cooking function of the cooking machine 10; step 22 includes: determining the flow rate of the coolant according to the desired temperature, the finished product temperature, the slurry quality, and the specific heat capacity of the slurry.

[0132] The specific heat capacity of the slurry, that is, the heat required for a unit mass of the slurry to rise or fall by 1 degree Celsius, depends on the specific composition of the slurry (such as the proportions of water, protein, fat, fiber, etc.) and state (such as temperature, pressure, etc.). Different slurries with different specific heat capacities require different amounts of heat when cooling. The cooking machine 10 includes a variety of functions, and these functions will process slurries with different compositions, structures, and physical properties. Therefore, the slurries obtained when the cooking machine 10 executes different functions often have different specific heat capacities. According to the cooking function of the cooking machine 10, the specific heat capacity of the slurry can be determined. When determining the flow rate of the coolant, considering the specific heat capacity of the slurry makes the flow rate of the coolant adapt to the cooking function, and the flow rate of the coolant can be determined more accurately. A mathematical model or a corresponding relationship table between the desired temperature, the finished product temperature, the slurry quality, the specific heat capacity of the slurry, and the flow rate can be established in advance through experiments. Substituting the desired temperature, the finished product temperature, the slurry quality, and the specific heat capacity of the slurry into this mathematical model or corresponding relationship table, the flow rate can be directly obtained.

[0133] Table 1 shows an embodiment of the corresponding relationship table between the desired temperature, the finished product temperature, the slurry quality, the specific heat capacity of the slurry, and the flow rate.

[0134]

[0135]

[0136] Table 1

[0137] Table 1 shows the corresponding relationships among the desired temperature, the finished product temperature, the slurry mass, the specific heat capacity of the slurry, and the flow rate when using a coolant with the same specific heat capacity (such as water) within the same cooling duration. It can be seen from Table 1 that the greater the difference between the finished product temperature and the desired temperature, the greater the slurry mass, the smaller the specific heat capacity of the slurry, and the faster the flow rate of the coolant needs to be in order to achieve the cooling effect within the same cooling duration. If a faster cooling effect is required, the flow rate of the coolant can be increased.

[0138] In some other embodiments, the flow rate of the coolant can be determined by formula (1).

[0139] v = m * c1 * (T2 - T1) / [t * c2 * (T4 - T3) * K] Formula (1)

[0140] Wherein, v is the flow rate of the coolant, m is the slurry mass, c1 is the specific heat capacity of the slurry, T2 is the finished product temperature of the slurry, T1 is the desired temperature, c2 is the specific heat capacity of the coolant, T4 is the temperature after heat exchange between the coolant and the slurry, T3 is the initial temperature of the coolant, K is the system cooling constant, and t is the cooling duration. The system cooling constant K is related to the hardware conditions of the system, and its value range is 0.1 - 1. The cooling duration t can be the expected value input by the user or the system setting value. For example, for soy milk with a mass of 600 g and a finished product temperature of 100 °C that needs to be cooled to 60 °C, with the initial temperature of the coolant being 25 °C and the temperature after heat exchange of the coolant being 60 °C, and the cooling duration t being 4 minutes, and k = 0.8, the coolant flow rate v ≈ 200 g / min can be obtained through formula (1).

[0141] The flow rate of the coolant obtained through formula (1) can enable the slurry to achieve the cooling effect within the set cooling duration. The flow rate of the coolant can also be determined to be greater than the rate obtained through formula (1). In this way, the slurry can be cooled more quickly, and the longest cooling duration of the slurry is the cooling duration t.

[0142] In some embodiments, the determining of the flow rate of the coolant includes:

[0143] After the slurry is made, determine the flow rate of the coolant based on the desired temperature, the finished product temperature, and the slurry mass as the initial flow rate;

[0144] Step 23 includes:

[0145] Control the coolant injection component 15 to make the coolant flow in the heat exchange cavity 14 at the initial flow rate for a set duration;

[0146] The determining of the flow rate of the coolant further includes:

[0147] After the set duration, obtain the current temperature of the slurry;

[0148] According to the current temperature, the desired temperature, and the quality of the slurry, re-determine the flow rate of the coolant as the adjusted flow rate, where the adjusted flow rate is less than the initial flow rate.

[0149] Step 23 further includes:

[0150] Control the coolant injection assembly 15 to flow the coolant in the heat exchange cavity 14 at the adjusted flow rate. During the flow of the coolant, when a certain period of time has elapsed after the initial moment when the coolant starts to flow (for example, when 1 minute has elapsed after the initial moment), obtain the current temperature of the slurry again, and determine the flow rate of the coolant according to the current temperature to adjust the flow speed of the coolant. It can be adjusted once until it cools down to the desired temperature. In some other embodiments, at multiple different moments, obtain the current temperature multiple times and adjust the flow rate of the coolant multiple times. In some embodiments, the flow rate of the coolant can be re-determined using formula (1). The period of time t can always use a fixed value, such as 4 minutes. Or the period of time that has already been cooled can be subtracted from the initially set period of time as the new period of time for calculating the flow rate. For example, if the initially set period of time is 4 minutes and the flow rate is re-determined after 1 minute, the period of time can be 3 minutes for calculating the flow rate.

[0151] During the flow of the coolant, as the temperature of the slurry drops, the flow rate of the coolant re-determined according to the current temperature of the slurry after the temperature reduction will also decrease accordingly. Controlling the coolant to flow at the re-determined flow rate can save the energy consumption of the cooking machine for recycled coolant and save the coolant for non-recycled coolant.

[0152] In some embodiments, the determining of the flow rate of the coolant includes:

[0153] Determine the flow rate as the initial flow rate according to the temperature difference between the initial temperature before the heat exchange between the coolant and the slurry and the set initial temperature rise after the heat exchange between the coolant and the slurry, or the set initial temperature difference before and after the heat exchange of the coolant.

[0154] Step 23 includes:

[0155] Control the coolant injection assembly 15 to flow the coolant in the heat exchange cavity 14 at the initial flow rate;

[0156] The determining of the flow rate of the coolant further includes: during the flow of the coolant, obtain the actual temperature difference before and after the heat exchange between the coolant and the slurry; according to the actual temperature difference, re-determine the flow rate as the adjusted flow rate;

[0157] Step 23 includes: controlling the coolant injection assembly 15 to make the coolant flow in the heat exchange cavity 14 at an adjusted flow rate.

[0158] In some embodiments, determining the specific heat capacity of the slurry according to the cooking function of the cooking machine 10 includes: before starting to make the slurry, obtaining the mass of the solid ingredients for making the slurry and the amount of water for making the slurry in the cooking cup 13; and determining the specific heat capacity of the slurry according to the mass of the ingredients and the amount of water.

[0159] The cooking function of the cooking machine 10 determines the way of making the slurry and its composition. The slurry is formed by mixing various solid ingredients (such as fruits, vegetables, nuts, etc.) and a certain amount of water. Different ingredients have different specific heat capacities. Therefore, the types and quantities of the ingredients will directly affect the overall specific heat capacity of the slurry. For example, the water content of fruits and vegetables is different, and the fat content of nuts is also different, all of which will affect the specific heat capacity of the slurry. Therefore, before making the slurry, it is necessary to accurately measure the mass of each solid ingredient in the cooking cup 13.

[0160] Water itself has a specific heat capacity, and the amount of water added will directly affect the total mass and overall specific heat capacity of the slurry. Therefore, before making the slurry, it is also necessary to accurately measure the amount of water added.

[0161] The mass of the ingredients and the amount of water can be input by the user or obtained by measuring the change in the weight of the cooking cup 13.

[0162] A mathematical model or corresponding relationship table between the mass of the ingredients, the amount of water, and the specific heat capacity of the slurry can be established in advance through experiments. Substituting the mass of the ingredients and the amount of water into this mathematical model or corresponding relationship table can directly obtain the specific heat capacity of the slurry.

[0163] The specific heat capacity of the slurry can be simply and conveniently determined through the mass of the ingredients and the amount of water.

[0164] In some embodiments, the control method 20 includes: during the process of controlling the coolant injection assembly 15 to make the coolant flow in the heat exchange cavity 14 at a flow rate, controlling the stirring blade assembly 19 to stir the slurry.

[0165] Stirring the slurry by the stirring blade assembly 19 can reduce the temperature of the slurry. During the process of the coolant flowing in the heat exchange cavity 14, the stirring blade assembly 19 stirs the slurry simultaneously, so that while the slurry exchanges heat with the coolant to reduce the temperature, it can also be cooled by stirring, which can further reduce the temperature of the slurry and make the temperature of the slurry reach the temperature required by the user faster.

[0166] In some embodiments, controlling the stirring blade assembly 19 to stir includes: determining the stirring rate of the stirring blade assembly 19 according to the desired temperature, the finished product temperature, and the mass of the slurry; and controlling the stirring blade assembly 19 to stir the slurry according to the stirring rate.

[0167] The stirring rate of the stirring blade assembly 19 is determined according to the desired temperature of the slurry, the finished product temperature when the slurry is made, and the quality of the slurry. A mathematical model or a corresponding relationship table between the desired temperature, the finished product temperature, the slurry quality and the stirring rate can be established in advance through experiments. Substituting the desired temperature, the finished product temperature, and the slurry quality into the mathematical model or the corresponding relationship table, the stirring rate can be directly obtained.

[0168] Table 2 shows an embodiment of the corresponding relationship between the desired temperature, the finished product temperature, the slurry quality and the stirring rate.

[0169]

[0170] Table 2

[0171] Table 2 shows the corresponding relationship between the desired temperature, the finished product temperature, the slurry quality and the stirring rate when using a coolant with the same specific heat capacity and within the same cooling time. It can be seen from Table 2 that for slurries of the same mass, if the same cooling effect is to be achieved, the greater the flow rate of the coolant, the smaller the corresponding stirring rate. By stirring the slurry, the effect of assisting the slurry to cool down can be achieved.

[0172] While controlling the stirring of the stirring blade assembly 19, the flow rate of the coolant can be re-determined, and the flow rate of the coolant can be appropriately reduced. So that the same cooling effect can be achieved by cooling with the coolant alone and by cooling with the coolant and stirring simultaneously.

[0173] According to the desired temperature, the finished product temperature and the slurry quality, the stirring rate can be determined more accurately, so that the slurry temperature can be reduced to a temperature that meets the user's requirements.

[0174] In some embodiments, controlling the stirring blade assembly 19 to stir the slurry includes:

[0175] In the first time period during the process of controlling the coolant injection assembly 15 to make the coolant flow in the heat exchange cavity 14 at a flow rate, control the stirring blade assembly 19 to stir the slurry according to the previous stirring rate;

[0176] In the second time period during the process of controlling the coolant injection assembly 15 to make the coolant flow in the heat exchange cavity 14 at a flow rate, control the stirring blade assembly 19 to stir the slurry according to the later stirring rate; The second time period is after the first time period, and the previous stirring rate is greater than the later stirring rate.

[0177] In the first time period, the slurry temperature is relatively high. Stirring at a higher stirring rate can make the slurry reach a uniform state faster and accelerate the heat dissipation of the slurry.

[0178] In the second time period, the temperature of the slurry is relatively low, and the temperature of the slurry gradually stabilizes, with the heat dissipation rate slowing down, resulting in a relatively reduced demand for the stirring rate. Controlling the stirring blade assembly 19 to stir the slurry at a lower late-stage stirring rate can not only maintain the uniform state of the slurry but also reduce unnecessary energy consumption.

[0179] Stirring at a higher stirring rate in the first time period and at a lower stirring rate in the second time period, with the stirring rate decreasing as the heat dissipation process progresses, can accelerate the rate of temperature reduction of the slurry while saving energy.

[0180] In some embodiments, controlling the stirring blade assembly 19 to stir the slurry includes:

[0181] In the first time period during the process of controlling the coolant injection assembly 15 to make the coolant flow in the heat exchange cavity 14 at a flow rate, controlling the stirring blade assembly 19 to intermittently stir the slurry at a first stop time interval;

[0182] In the second time period during the process of controlling the coolant injection assembly 15 to make the coolant flow in the heat exchange cavity 14 at a flow rate, controlling the stirring blade assembly 19 to intermittently stir the slurry at a second stop time interval; the second time period is after the first time period, and the second stop time interval is greater than the first stop time interval.

[0183] In the first time period, the temperature of the slurry is relatively high. Intermittently stirring the slurry at a shorter time interval can make the slurry reach a uniform state faster and accelerate the heat dissipation of the slurry.

[0184] In the second time period, the temperature of the slurry is relatively low, and the temperature of the slurry gradually stabilizes, with the heat dissipation rate slowing down. Controlling the stirring blade assembly 19 to intermittently stir the slurry at a longer time interval can not only maintain the uniform state of the slurry but also reduce unnecessary energy consumption.

[0185] Intermittently stirring at a shorter time interval in the first time period and at a longer time interval in the second time period, with the time interval of intermittent stirring extending as the heat dissipation process progresses, can accelerate the rate of temperature reduction of the slurry while saving energy.

[0186] In some embodiments, the control method 20 further includes:

[0187] During the process of controlling the coolant injection assembly 15 to make the coolant flow in the heat exchange cavity 14 at a flow rate, obtaining the real-time temperature of the slurry. If the real-time temperature of the slurry is less than or equal to the desired temperature, controlling the stirring blade assembly 19 to stir the slurry; after stirring, obtaining the real-time temperature of the slurry again; if the real-time temperature is still less than or equal to the desired temperature, controlling the coolant injection assembly 15 to stop working.

[0188] During the process of heat exchange between the slurry and the coolant to reduce the temperature, the real-time temperature of the slurry is detected in real time to see if it reaches the desired temperature. If the real-time temperature of the slurry reaches the desired temperature, the slurry is stirred to make the inside of the slurry more uniform and prevent the temperature of different parts of the slurry from being inconsistent. After stirring, the temperatures of all parts of the slurry tend to be the same. If the real-time temperature of the slurry is still less than or equal to the desired temperature, it is considered that the slurry has been successfully cooled to the desired temperature. Otherwise, it is considered that the slurry has not been completely cooled to the desired temperature, and the slurry continues to be cooled. In this way, it is possible to more accurately determine whether the slurry has reached the desired temperature.

[0189] In some embodiments, the control method 20 further includes: during the process of controlling the coolant injection component 15 to make the coolant flow in the heat exchange cavity 14 at a flow rate, controlling the exhaust system 131 to blow air into the cooking cup 13.

[0190] Blowing air into the cooking cup 13 can reduce the temperature of the slurry. During the process of the coolant flowing in the heat exchange cavity 14, controlling the exhaust system 131 to blow air into the cooking cup 13 enables, while the slurry exchanges heat with the coolant to reduce the temperature, further reducing the temperature of the slurry by blowing air at the same time, so that the temperature of the slurry reaches the desired temperature faster. In addition, blowing air through the exhaust system 131 can accelerate the evaporation of water in the slurry and improve the quality and taste of the cooked food.

[0191] In some embodiments, controlling the exhaust system 131 to blow air into the cooking cup 13 includes: determining the air flow rate of the exhaust system 131 according to the desired temperature, the finished product temperature, and the mass of the slurry; controlling the exhaust system to blow air into the cooking cup 13 according to the air flow rate.

[0192] A mathematical model or a corresponding relationship table between the desired temperature, the finished product temperature, the mass of the slurry, and the air flow rate can be established in advance through experiments. Substituting the desired temperature, the finished product temperature, and the mass of the slurry into this mathematical model or corresponding relationship table can directly obtain the air flow rate.

[0193] While controlling the exhaust system 131 to blow air into the cooking cup 13, the flow rate of the coolant can be re-determined, and the flow rate of the coolant can be appropriately reduced. This enables achieving the same cooling effect by cooling solely through the coolant and by cooling through the coolant and blowing air simultaneously.

[0194] According to the desired temperature, the finished product temperature, and the mass of the slurry, the air flow rate can be accurately determined, and thus the cooling process of the slurry can be accurately controlled.

[0195] In practical applications, according to the actual situation of the slurry, one or a combination of cooling methods such as cooling through the coolant, cooling through stirring, and cooling through blowing can be flexibly selected.

[0196] In some embodiments, the control method 20 further includes: determining the required capacity of the coolant according to the desired temperature, the finished product temperature, and the slurry quality; if the capacity of the coolant in the liquid storage tank 151 does not reach the required capacity, generating a capacity shortage reminder signal.

[0197] A mathematical model or a corresponding relationship table between the desired temperature, the finished product temperature, the slurry quality, and the required capacity of the coolant can be pre-established through experiments. Substituting the desired temperature, the finished product temperature, and the slurry quality into the mathematical model or the corresponding relationship table can directly obtain the required capacity of the coolant.

[0198] If the capacity of the coolant in the liquid storage tank 151 does not reach the required capacity, effective heat exchange may not be possible, thus affecting the temperature control of the slurry and the quality of the finished product. At this time, a capacity shortage reminder signal is generated to remind the user to replenish the coolant in a timely manner.

[0199] The reminder signal can be presented to the user in various ways, such as sound alarm, light flashing, or screen display, etc. The purpose is to ensure that the user can timely discover the problem of insufficient coolant and take corresponding measures to replenish it, thereby ensuring the normal operation of the cooking machine 10 and the quality of the slurry.

[0200] In this way, it can prevent the slurry from not being able to be reduced to the desired temperature due to insufficient coolant, and improve the user experience.

[0201] Figure 4 The figure shows a schematic structural diagram of another embodiment of the cooking machine 10 of the present application.

[0202] The coolant injection assembly 15 includes a liquid storage tank 151 and a refrigeration assembly 153 provided on the liquid storage tank 151. The control method 20 further includes: during the process of controlling the cooking machine 10 to make slurry, controlling the refrigeration assembly 153 to refrigerate the coolant.

[0203] The refrigeration assembly 153 is provided on the outer shell of the liquid storage tank 151. The refrigeration assembly 153 can cool down the coolant stored in the liquid storage tank 151, so that when the coolant enters the heat exchange cavity 14, it can absorb more heat. The refrigeration assembly 153 includes a semiconductor refrigeration cavity and a compression refrigeration cavity.

[0204] During the process of making slurry, refrigerating the coolant makes the temperature of the coolant lower after the slurry making is completed. When the coolant flows into the heat exchange cavity 14, the temperature is lower, and it can absorb more heat of the slurry, which can accelerate the cooling speed of the slurry.

[0205] Figure 5 The figure shows a schematic structural diagram of another embodiment of the cooking machine 10 of the present application.

[0206] The coolant injection assembly 15 includes a water tank 16 for storing water, a water pump 152 connecting the cooking cup 13 and the water tank 16, as well as connecting the heat exchange cavity 14 and the water tank 16. The coolant is the water in the water tank 16.

[0207] Step 21 includes: according to the cooking function of the cooking machine 10, controlling the water pump 152 to inject the water in the water tank 16 into the cooking cup 13; Step 23 includes: controlling the water pump 152 to inject the water in the water tank 16 into the heat exchange cavity 14.

[0208] The water pump 152 can inject the water in the water tank 16 into the cooking cup 13 or into the heat exchange cavity 14. When making the slurry, the water pump 152 injects the water in the water tank 16 into the cooking cup 13 and mixes it with the ingredients in the cooking cup 13 to form the slurry. When the slurry needs to be cooled after being made, the water pump 152 injects the water in the water tank 16 into the heat exchange cavity 14 to exchange heat with the slurry in the cooking cup 13 and cool down the slurry.

[0209] The water in the water tank 16 can be used both in the process of making the slurry and in the process of cooling the slurry, improving the utilization rate of the water tank 16 and the space utilization rate of the cooking machine 10. The water in the water tank 16 can also be used to clean the cooking cup 13 after the slurry is made.

[0210] The heat exchange cavity 14 includes a water inlet 141 and a water outlet 142. The water inlet 141 is connected to the outlet of the water pump 152, and the water outlet 142 is connected to the water tank 16.

[0211] Controlling the water pump 152 to inject the water in the water tank 16 into the heat exchange cavity 14 includes: controlling the water pump 152 to inject the water in the water tank 16 into the heat exchange cavity 14 so that the water circulates between the water tank 16 and the heat exchange cavity 14.

[0212] Figure 5 The line segment A in... indicates the flow direction of the water. The water pump 152 pumps the water out of the water tank 16 and injects it into the heat exchange cavity 14 from the water inlet 141. After the water exchanges heat with the slurry, it flows out of the heat exchange cavity 14 from the water outlet 142. The water flowing out of the heat exchange cavity 14 flows into the water tank 16 for recycling. The heat exchange cavity 14 may include multiple water inlets 141 and / or multiple water outlets 142.

[0213] The water circulates between the water tank and the heat exchange cavity, enabling the water to be reused and saving energy.

[0214] Figure 6 The figure shows a schematic structural diagram of another embodiment of the cooking machine 10 of the present application.

[0215] As Figure 6As shown, the water outlet 142 is located above the waste water recovery container 171, and the waste water recovery container 171 is used to receive the water flowing out of the heat exchange cavity 14.

[0216] The water flowing out of the heat exchange cavity 14 no longer flows into the water tank 16, but into the waste water recovery container 171. The waste water recovery container 171 collects the water, which can be used for other purposes. Setting up the waste water recovery container 171 can save water resources and be more environmentally friendly.

[0217] Figure 7 As shown is a schematic structural diagram of another embodiment of the cooking machine 10 of the present application.

[0218] The cooking machine 10 includes a main body 30, and the cooking cup assembly 11 is separately arranged from the main body 30. The liquid storage tank 151 and the driving device 152 are arranged on the main body 30. The main body 30 further includes a motor 31 for driving the stirring blade assembly 19 to work. The main body 30 includes a connection port 32. When the cooking cup assembly 11 is assembled to the main body 30, the connection port 32 is respectively docked with the water inlet 141 and the water outlet 142, so that the coolant stored in the liquid storage tank 151 can enter the heat exchange cavity 14 through the water inlet 141 and flow back to the liquid storage tank 151 from the heat exchange cavity 14 through the water outlet 142.

[0219] Figure 8 As shown is a schematic structural diagram of another embodiment of the cooking machine 10 of the present application.

[0220] The cooking cup assembly 11 and the main body 30 are separately arranged. The driving device 152 is arranged on the main body 30. The driving device 152 is a water pump. The water in the water tank 16 is used for cooling the slurry.

[0221] Figure 9 As shown is a schematic structural diagram of another embodiment of the cooking machine 10 of the present application.

[0222] The cooking machine 10 includes an instant heating component 191, which is arranged on the upper water pipeline between the water pump 152 and the cooking cup 13. The instant heating component 191 can heat the water flowing through it. When making the slurry, the instant heating component 191 is turned on to increase the temperature of the water entering the cooking cup 13, which can speed up the slurry making speed and shorten the slurry making time. Specifically, in the early stage of making the slurry, a small amount of hot water can be added, and in the later stage of making the slurry, after the ingredients are cooked and the enzymes are inactivated, a large amount of hot water can be added.
