[0001] The invention belongs to ice drink making technology, and in particular relates to a beverage making machine and a beverage making method for making slush and the like. Background Art

[0002] When making ice drinks such as muddy and paste-like slush, the evaporator condenses the beverage in the barrel into ice on the surface of the evaporator, and the motor drives the reamer to rotate and scrape off the ice condensed on the surface of the evaporator until the ice drink reaches a stable shape and appears as slush, which is maintained. In the production method of the existing beverage making machine, the rotation speed of the reamer is constant, which is not suitable for the shape of the beverage at different production stages, resulting in slow freezing in the initial stage of production and easy formation of large ice cubes in the maintenance stage. Summary of the invention

[0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defects of the prior art that the reamer rotates at a constant speed, resulting in slow freezing in the initial stage and easy formation of large ice cubes in the holding stage, and to provide a beverage making machine and a beverage making method, which are intended to promote rapid freezing of the beverage in the initial stage of beverage production and avoid condensation into large ice cubes in the later holding stage.

[0004] To achieve the above object, the beverage making machine of the present invention comprises:

[0005] The evaporator is cylindrical and fixedly arranged laterally;

[0006] A reamer rotatably mounted on the evaporator;

[0007] A stirring power device, comprising a motor and a transmission shaft driven by the motor, wherein the transmission shaft is coaxially arranged through the center of the evaporator, and the front end of the transmission shaft extends to the front side of the evaporator and is connected to a reamer;

[0008] The barrel is detachably mounted on the evaporator and the reamer through the through hole at the rear end, the rear end of the barrel in contact with the body is kept sealed, and the barrel is provided with a feeding port and a discharging port;

[0009] A signal collector, used to collect data on the working condition of the beverage making machine;

[0010] The controller controls the speed of the motor according to the data collected by the signal collector.

[0011] Accordingly, the beverage making machine can change the rotation speed of the reamer according to the data change of its working condition, which is suitable for quickly making ice drinks and keeping the ice drinks in a suitable state.

[0012] Preferably, the signal collector includes a temperature sensor, and the controller controls the speed of the motor according to the temperature data collected by the temperature sensor. The temperature sensor can directly collect the temperature of the beverage and directly reflect the shape of the beverage, which is conducive to controlling the ice drink in an ideal shape.

[0013] Preferably, the feed port is located at the rear end of the top of the barrel, the discharge port is located at the front end of the bottom of the barrel, and the temperature sensor is sealed and assembled on the front end face of the evaporator and protrudes from the inner cavity of the barrel. In this way, the beverage temperature collected by the temperature sensor is the actual temperature after cooling, not the temperature of the raw materials just added. The collected signal is more accurate and can truly reflect the temperature of the iced beverage discharged from the discharge port. Moreover, arranging the temperature sensor on the front end face of the evaporator can avoid interference with the rotation of the reamer.

[0014] Preferably, the front end face of the evaporator is provided with a bearing seat, the transmission shaft is rotatably assembled on the bearing seat via the bearing, the bearing seat protrudes from the front end face of the evaporator, and the temperature sensor is lower than the bearing seat along the axial direction of the evaporator. In this way, the temperature sensor can be immersed in the beverage to directly and truly collect the temperature of the beverage. In addition, since the temperature sensor is lower than the bearing seat along the axial direction of the evaporator, interference with the rotation of the reamer can be avoided.

[0015] Preferably, the motor is a DC motor, the signal collector includes a motor condition sensor, and the controller controls the speed of the motor according to the data collected by the motor condition sensor. Due to different loads, the working parameters of the motor will change. For example, when the beverage is a liquid, the resistance to the reamer is small, the working current of the motor is also small, the motor output power is also small, and the motor heat generation is small. When the beverage is a mixture of slush and liquid, the resistance to the reamer increases, the working current of the motor also increases, the motor output power also increases, and the motor heat generation is large. Therefore, the working parameters of the motor indirectly reflect the shape of the ice drink, and the speed of the motor and the reamer is controlled by collecting the working data of the motor.

[0016] Preferably, the reamer includes at least two stirring arms, which extend in a spiral shape along the cylindrical surface of the evaporator, the front end of the stirring arm is widened to form a pushing surface, the inner edge of the pushing surface is connected to the shaft connecting portion, the shaft connecting portion is assembled to the transmission shaft, and the adjacent part of the pushing surface and the stirring arm has a notch, the notch has an axial edge, and the axial edge is close to the front end surface of the evaporator. Accordingly, the matching relationship between the reamer and the evaporator is ensured, and as the reamer rotates, the axial edge can scrape the ice condensed on the front end surface of the evaporator to avoid ice condensation here causing errors in the data collected by the temperature sensor.

[0017] Preferably, the reamer includes a support ring and at least two support rods, the support ring is sleeved on the rear end of the evaporator, the support rod extends forward from the support ring and is connected to the stirring arm at the intersection with the stirring arm, and the notch is located at the front end of the support rod. Accordingly, the rigidity of the reamer can be increased to prevent the reamer from being deformed by resistance when rotating. In addition, the notch is located at the front end of the support rod, which can increase the rigidity at the notch.

[0018] The beverage manufacturing method of the present invention comprises: an evaporator condenses the beverage in the barrel into ice on the surface of the evaporator, and a motor drives a reamer to rotate to scrape off the ice condensed on the surface of the evaporator, and the method is characterized in that:

[0019] The initial stage of making ice drinks causes the motor to rotate with the reamer at a slower speed;

[0020] Using a signal collector to collect data on the working condition of the beverage making machine;

[0021] The controller is used to control the motor to change the speed of the reamer according to the changes in the data collected by the signal collector.

[0022] Accordingly, the rotation speed of the reamer can be changed according to the data change of the working condition of the beverage making machine, which is suitable for quickly making ice drinks and keeping the ice drinks in a suitable state.

[0023] Preferably, the data changes are the temperature value of the beverage and / or the working current of the motor. When the temperature value of the beverage decreases and / or the working current of the motor increases, the controller controls the motor to increase the speed of the reamer. When the temperature value of the beverage increases and / or the working current of the motor decreases, the controller controls the motor to reduce the speed of the reamer.

[0024] In the initial stage of making ice drinks, when the reamer rotates faster, the beverage is not conducive to condensing into ice on the evaporator surface due to the high temperature of the beverage. Therefore, in the initial stage of making ice drinks, the motor is driven by the reamer to rotate at a slower speed, so that the beverage in contact with the evaporator surface has sufficient cooling time to condense into ice. After the slush is formed, the temperature of the beverage decreases. If the reamer is rotated at a lower speed, thicker ice will be formed on the evaporator surface, which is not conducive to the reaming of the reamer and will also increase the motor load, causing damage to the motor. Therefore, by collecting the temperature value of the beverage and / or the working current of the motor to control the motor speed, an ideal slush ice drink can be obtained, and the motor load and the risk of motor damage can be reduced.

[0025] Preferably, when the temperature of the beverage decreases or / and the current of the motor increases, the controller controls the evaporator to reduce the cooling power, and when the temperature of the beverage increases or / and the current of the motor decreases, the controller controls the evaporator to increase the cooling power. Accordingly, the liquid beverage can be quickly cooled in the initial stage of making an iced beverage, and the formation of large ice cubes can be avoided in the later holding stage.

[0026] Preferably, different types of beverages are selected as needed, and the method is automatically executed for different types of beverages respectively.

[0027] Preferably, the operating temperature and operating current of the motor are detected in real time, and when the actual operating temperature value of the motor is greater than the set safety temperature value, or when the actual operating current value of the motor is greater than the set safety current value, the power supply circuit of the motor and the refrigeration system is disconnected.

[0028] The present invention uses an evaporator to condense the beverage in the barrel into ice on the surface of the evaporator, and a motor drives a reamer to rotate to scrape off the ice condensed on the surface of the evaporator; in the initial stage of making ice drinks, the motor drives the reamer to rotate at a slower speed; a signal collector is used to collect data on the working condition of the beverage making machine; a controller is used to control the motor to drive the reamer to change the speed according to the changes in the data collected by the signal collector. Accordingly, the speed of the reamer can be changed according to the changes in the data on the working condition of the beverage making machine, which is suitable for quickly making ice drinks and keeping the ice drinks in a suitable state. In addition, the motor can be prevented from being overloaded and the risk of motor damage can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The terms "including" and "having" and any variations thereof in the specification and claims of the present invention are intended to cover non-exclusive inclusions. For example, a method or product comprising a series of technical features is not necessarily limited to those technical features clearly listed, but may also include other technical features that are not clearly listed and can be included in the method or product.

[0045] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", etc. are based on the directions or positional relationships shown in the 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Among them, "upper" and "lower", "left" and "right", "front" and "back" are opposite directions.

[0046] The present invention is described in detail below in conjunction with specific embodiments and accompanying drawings.

[0047] Figure 1-3 A beverage making machine is shown, which is used for making ice drinks such as muddy and paste-like slush. The beverage making machine comprises a machine body 100, a refrigeration system, a stirring power device, a reamer 400 and a barrel 500.

[0048] The refrigeration system includes a compressor 220, a condenser, and an evaporator 210. When working, the refrigerant flows and changes its physical state in the refrigeration system through the delivery of the compressor to achieve refrigeration. Specifically, the refrigerant evaporates and absorbs heat in the evaporator to achieve refrigeration, and the refrigerant condenses in the condenser to generate heat. The compressor 220 and the condenser are located in the body 100, and the evaporator 210 is arranged horizontally on the upper side of the water collecting box 110 of the body in a cylindrical shape.

[0049] The stirring power device includes a motor 310 and a transmission shaft 320 driven by the motor. The motor 310 is located in the body 100 . The transmission shaft 320 is coaxially arranged in the center of the evaporator 210 . The front end of the transmission shaft 320 extends to the front side of the evaporator 210 .

[0050] The reamer 400 is a spiral member, which is rotatably mounted on the evaporator 210 and connected to the front end of the transmission shaft 320. Therefore, the reamer can rotate around the evaporator under the drive of the motor, scrape the ice-like food condensed on the surface of the evaporator into slush and stir the slush to make it uniform.

[0051] The barrel 500 is used as a container for containing food. The rear end of the barrel 500 has a through hole, and the barrel can be detachably sleeved on the outside of the evaporator 210 and the reamer 400 through the through hole at the rear end. In other words, in the assembled state, the evaporator 210 and the reamer 400 are located in the barrel 500. The evaporator cools the food, and the reamer scrapes and stirs the food. The rear end of the barrel 500 is sealed at the part in contact with the fuselage. For example, a sealing ring 501 is configured here. When the barrel is assembled in place, the sealing ring 501 is squeezed to achieve sealing. In order to maintain the seal, after the barrel is installed in place, the barrel is locked here with a locking pin 120 or other locking structures as shown in the figure. The rear end of the top of the barrel 500 is provided with a feeding port 502 for feeding into the barrel, and the front end of the bottom of the barrel 500 is provided with a discharge port 503 that can be opened and closed. Generally, a valve 504 is configured for the discharge port, and the discharge port is opened or closed by the valve.

[0052] The beverage making machine, such as Figure 6 The device shown includes a signal collector and a controller 700. The signal collector is used to collect data on the working condition of the beverage making machine. The controller controls the speed of the motor according to the data collected by the signal collector. Accordingly, the beverage making machine can change the speed of the reamer according to the data changes of its working condition, which is suitable for quickly making ice drinks and keeping the ice drinks in a suitable state.

[0053] Specifically, the signal collector includes a temperature sensor 610, and the controller 700 controls the speed of the motor according to the temperature data collected by the temperature sensor 610. The temperature sensor can directly collect the temperature of the beverage and directly reflect the shape of the beverage, which is conducive to controlling the ice drink in an ideal shape.

[0054] like Figure 4 , Figure 5 As shown, the temperature sensor 610 is sealed and assembled on the front end face 212 of the evaporator 210 and protrudes from the inner cavity of the barrel 500 to prevent the beverage in the barrel from leaking into the evaporator. Moreover, the beverage temperature collected by the temperature sensor is the actual temperature after cooling, not the temperature of the raw materials just added. The collected signal is more accurate and can truly reflect the temperature of the iced beverage discharged from the discharge port. Moreover, arranging the temperature sensor on the front end face of the evaporator can avoid interference with the rotation of the reamer.

[0055] In the beverage making machine, the front end face 212 of the evaporator 210 is provided with a bearing seat 211, the transmission shaft 320 is rotatably assembled on the bearing seat 211 via a bearing, the bearing seat 211 protrudes from the front end face 212 of the evaporator, and the temperature sensor 610 is lower than the bearing seat 211 along the axial direction of the evaporator. In this way, the temperature sensor can be immersed in the beverage to directly and truly collect the temperature of the beverage. In addition, since the temperature sensor is lower than the bearing seat along the axial direction of the evaporator, interference with the rotation of the reamer can be avoided.

[0056] In the beverage making machine, the motor 310 is a DC motor, the signal collector includes a motor condition sensor 620, and the controller 700 controls the speed of the motor according to the data collected by the motor condition sensor. Due to different loads, the working parameters of the motor will change. For example, when the beverage is a liquid, the resistance to the reamer is small, the working current of the motor is also small, the motor output power is also small, and the motor heat generation is small. When the beverage is a mixture of slush and liquid, the resistance to the reamer increases, the working current of the motor also increases, the motor output power also increases, and the motor heat generation is large. Therefore, the working parameters of the motor indirectly reflect the form of the ice drink, and the speed of the motor and the reamer is controlled by collecting the working data of the motor.

[0057] The beverage making machine, reamer 400 as Figure 5 As shown, at least two stirring arms 410 are included, and the stirring arms 410 extend in a spiral shape along the cylindrical surface of the evaporator 210. The front end of the stirring arms 410 is widened to form a pushing surface 420. The inner edge of the pushing surface 420 is connected to the shaft connecting portion 430, and the shaft connecting portion 430 is assembled on the transmission shaft 320. There is a notch 440 at the junction of the pushing surface 420 and the stirring arms 410. The notch 440 has an axial edge 450, and the axial edge 450 is close to the front end surface 212 of the evaporator. Accordingly, the matching relationship between the reamer and the evaporator is ensured, and as the reamer rotates, the axial edge can scrape the ice condensed on the front end surface of the evaporator to avoid ice condensation here causing errors in the data collected by the temperature sensor.

[0058] like Figure 5As shown, the reamer 400 of the beverage making machine includes a support ring 460 and at least two support rods 470. The support ring 460 is sleeved on the rear end of the evaporator 210. The support rods 470 extend forward from the support ring 460 and are connected to the stirring arm 410 at the intersection. The notch 440 is located at the front end of the support rod 470. Accordingly, the rigidity of the reamer can be increased to prevent the reamer from being deformed when encountering resistance when rotating. In addition, the notch is located at the front end of the support rod, which can increase the rigidity at the notch.

[0059] In view of the above beverage making machine, ice drinks such as slush are made by the following method:

[0060] The liquid beverage is added to the barrel, and the evaporator condenses the beverage in the barrel into ice on the surface of the evaporator, and the motor drives the reamer to rotate and scrape off the ice condensed on the surface of the evaporator. In addition, in the initial stage of making ice drinks, the motor drives the reamer to rotate at a slower speed; the signal collector is used to collect data on the working condition of the beverage making machine; the controller is used to control the motor to drive the reamer to change the speed according to the changes in the data collected by the signal collector. Accordingly, the speed of the reamer can be changed according to the changes in the data on the working condition of the beverage making machine, which is suitable for quickly making ice drinks and keeping the ice drinks in a suitable state.

[0061] In the method, the data changes are the temperature value of the beverage and / or the working current of the motor. When the temperature value of the beverage decreases and / or the working current of the motor increases, the controller controls the motor to increase the speed of the reamer. When the temperature value of the beverage increases and / or the working current of the motor decreases, the controller controls the motor to reduce the speed of the reamer.

[0062] In the initial stage of making ice drinks, when the reamer rotates faster, the beverage is not conducive to condensing into ice on the evaporator surface due to the high temperature of the beverage. Therefore, in the initial stage of making ice drinks, the motor is driven by the reamer to rotate at a slower speed, so that the beverage in contact with the evaporator surface has sufficient cooling time to condense into ice. After the slush is formed, the temperature of the beverage decreases. If the reamer is rotated at a lower speed, thicker ice will be formed on the evaporator surface, which is not conducive to the reaming of the reamer and will also increase the motor load, causing damage to the motor. Therefore, by collecting the temperature value of the beverage and / or the working current of the motor to control the motor speed, an ideal slush ice drink can be obtained, and the motor load and the risk of motor damage can be reduced.

[0063] In the method, when the temperature of the beverage decreases or / and the current of the motor increases, the controller controls the evaporator to reduce the cooling power, and when the temperature of the beverage increases or / and the current of the motor decreases, the controller controls the evaporator to increase the cooling power. Accordingly, the liquid beverage can be quickly cooled in the initial stage of making an iced beverage, and the formation of large ice cubes can be avoided in the later holding stage.

[0064] In the method, the beverage maker is given the function of making different ice drinks, and the user can select the corresponding function button or working mode to start the working mode of the corresponding beverage as needed. Different types of beverages are selected as needed, and the above method is automatically executed for different types of beverages.

[0065] In addition, the motor is equipped with protection means, such as real-time detection of the working temperature and working current of the motor, and disconnecting the power supply circuit of the motor and the refrigeration system when the actual working temperature value of the motor is greater than the set safety temperature value, or when the actual working current value of the motor is greater than the set safety current value. Disconnecting the power supply circuit of the motor and the refrigeration system can be done by directly disconnecting the power supply circuit of the motor and the refrigeration system by a corresponding switch such as a temperature switch or an overcurrent switch, or by controlling the disconnection of the power supply circuit of the motor and the refrigeration system by a controller.

[0066] According to the beverage making machine and method, when making beverages, liquid beverage is added to the barrel, the corresponding working mode is started, the evaporator condenses the beverage in the barrel into ice on the surface of the evaporator, and the motor drives the reamer to rotate and scrape off the ice condensed on the surface of the evaporator. In the initial stage, the motor drives the reamer to rotate at a slower speed, and the slower speed is a set value. At the same time, the temperature sensor is used to collect the temperature of the beverage, and the motor condition sensor is used to detect the working current of the motor. When the temperature value of the beverage decreases or / and the working current of the motor increases, the controller controls the motor to increase the speed of the reamer, and when the temperature value of the beverage increases or / and the working current of the motor decreases, the controller controls the motor to reduce the speed of the reamer. In addition, when the temperature value of the beverage decreases or / and the working current of the motor increases, the controller controls the evaporator to reduce the cooling power, and when the temperature value of the beverage increases or / and the working current of the motor decreases, the controller controls the evaporator to increase the cooling power. Accordingly, the liquid beverage can be quickly cooled in the initial stage of making ice drinks, and the formation of large ice cubes can be avoided in the later holding stage.

[0067] The change in the beverage temperature is preferably compared with a set temperature value, that is, the difference between the actual measured temperature value and the set temperature value. When the temperature difference increases, it is considered that the beverage temperature increases, and when the temperature difference decreases, it is considered that the beverage temperature decreases. Similarly, the actual working current of the motor is preferably compared with a set current value, that is, the difference between the actual measured current value and the set current value. When the current difference increases, it is considered that the motor current increases, and when the current difference decreases, it is considered that the motor current decreases.
