[0001] The utility model belongs to ice drink production technology, concretely relates to a beverage manufacturing machine for making snow mud and the like. BACKGROUND

[0002] The ice drink in the form of mud and paste, such as snow mud, is condensed into ice on the surface of the evaporator by the evaporator during production, and the ice condensed on the surface of the evaporator is scraped down by the reamer rotating with the motor until the ice drink is in the form of snow mud when it is kept. The production method of the existing beverage manufacturing machine has a constant rotating speed of the reamer, which is not suitable for the form of the beverage at different production stages, resulting in slow ice formation at the initial production stage and easy formation of large ice blocks at the keeping stage. SUMMARY

[0003] The technical problem to be solved and the technical task proposed by the utility model are to overcome the defects of slow ice formation at the initial production stage and easy formation of large ice blocks at the keeping stage caused by the constant rotating speed of the reamer in the prior art, and to provide a beverage manufacturing machine, which aims to promote rapid ice formation of the beverage at the initial production stage and avoid the condensation into large ice blocks at the later keeping stage.

[0004] To achieve the above-mentioned purpose, the beverage manufacturing machine of the utility model comprises:

[0005] The evaporator is horizontally fixed in a cylindrical shape;

[0006] The reamer is rotatably sleeved on the evaporator;

[0007] The stirring power device comprises a motor and a transmission shaft driven by the motor, the transmission shaft is coaxially arranged in the center of the evaporator, the front end of the transmission shaft extends to the front side of the evaporator and is connected with the reamer;

[0008] The barrel is detachably sleeved outside the evaporator and the reamer through the through hole at the rear end, the part of the rear end of the barrel in contact with the machine body is kept sealed, and the barrel is provided with a charging port and a discharging port;

[0009] The signal collector is used for collecting the data of the working condition of the beverage manufacturing machine;

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

[0011] Accordingly, the beverage manufacturing machine can change the rotating speed of the reamer according to the data of the working condition, which is suitable for quickly producing the ice drink and keeping the ice drink in a suitable state.

[0012] Preferably, the signal collector comprises a temperature sensor, and the controller controls the rotating 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 form of the beverage, which is beneficial to control the ice drink in an ideal form.

[0013] Preferably, the feeding port is located at the rear end of the top of the barrel, the discharging port is located at the front end of the bottom of the barrel, and the temperature sensor is sealingly assembled to the front end surface of the evaporator and protrudes into the inner cavity of the barrel. In this way, the temperature of the beverage collected by the temperature sensor is the actual temperature after cooling, rather than the temperature of the raw material just added, the collected signal is more accurate, and the temperature of the ice beverage discharged from the discharging port can be truly reflected. Moreover, arranging the temperature sensor on the front end surface of the evaporator can avoid interference with the rotation of the reamer.

[0014] Preferably, the front end surface of the evaporator is provided with a bearing seat, the transmission shaft is rotatably assembled to the bearing seat through a bearing, the bearing seat protrudes from the front end surface of the evaporator, and the temperature sensor is lower than the bearing seat in 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. Moreover, since the temperature sensor is lower than the bearing seat in the axial direction of the evaporator, interference with the rotation of the reamer can be avoided.

[0015] Preferably, the motor is a direct current motor, the signal collector includes a motor condition sensor, and the controller controls the rotating speed of the motor according to the data collected by the motor condition sensor. Since the working parameters of the motor change when the load changes, for example, when the beverage is liquid, the resistance to the reamer is small, the working current of the motor is also small, the output power of the motor is also small, and the heat generated by the motor is small; when the beverage is a mixture of snow and liquid, the resistance to the reamer increases, the working current of the motor also increases, the output power of the motor also increases, and the heat generated by the motor increases. Therefore, the working parameters of the motor indirectly reflect the form of the ice beverage, and the rotating speed of the motor and the reamer can be controlled by collecting the working data of the motor.

[0016] Preferably, the reamer includes at least two stirring arms, the stirring arms 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 a shaft connecting portion, the shaft connecting portion is assembled to the transmission shaft, the pushing surface and the stirring arm have a notch at the abutting position, the notch has an axial edge close to the front end surface of the evaporator. In this way, the cooperation relationship between the reamer and the evaporator is ensured, and the axial edge can scrape the ice condensed on the front end surface of the evaporator as the reamer rotates, so that the error in the data collected by the temperature sensor due to the ice block condensed at the front end surface of the evaporator can be avoided.

[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 rods extend forward from the support ring and are connected to the stirring arms at the intersection positions, and the notch is located at the front end of the support rod. In this way, the rigidity of the reamer can be increased to avoid deformation of the reamer when it rotates. Moreover, the notch is located at the front end of the support rod, so that the rigidity at the notch can be increased.

[0018] The beverage manufacturing machine works according to the following method: the evaporator condenses the beverage in the barrel into ice on the surface of the evaporator, and the motor drives the reamer to rotate to scrape off the ice condensed on the surface of the evaporator, characterized in that:

[0019] The motor drives the reamer to rotate at a slow speed in the initial stage of making ice drinks;

[0020] The signal collector collects data of the working condition of the beverage manufacturing machine;

[0021] The controller controls the motor driving the reamer to change the speed according to the change of the data collected by the signal collector.

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

[0023] Preferably, the change of the data is the temperature value of the beverage and / or the working current of the motor, and the controller controls the motor driving the reamer to increase the speed when the temperature value of the beverage decreases and / or the working current of the motor increases, and the controller controls the motor driving the reamer to decrease the speed when the temperature value of the beverage increases and / or the working current of the motor decreases.

[0024] In the initial stage of making ice drinks, the reamer rotates faster, and since the temperature of the beverage is higher, it is not conducive to the condensation of the beverage into ice on the surface of the evaporator, therefore, the motor drives the reamer to rotate at a slow speed in the initial stage of making ice drinks, so that the beverage in contact with the surface of the evaporator has sufficient cooling time to condense into ice. After the formation of slush, the temperature of the beverage decreases, and if the reamer rotates at a lower speed, a thicker ice will be formed on the surface of the evaporator, which is not conducive to the scraping of the reamer, and will also increase the load of the motor, 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 speed of the motor, the ideal slush ice drink can be made, and the risk of damage to the motor can be reduced.

[0025] Preferably, the controller controls the evaporator to reduce the refrigeration power when the temperature value of the beverage decreases and / or the working current of the motor increases, and the controller controls the evaporator to increase the refrigeration power when the temperature value of the beverage increases and / or the working current of the motor decreases. Accordingly, the liquid beverage can be quickly cooled in the initial stage of making ice drinks, and large ice blocks can be avoided in the later keeping 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 working temperature and working current of the motor are detected in real time, and when the actual working temperature value of the motor is greater than the set safe temperature value or when the actual working current value of the motor is greater than the set safe current value, the power supply circuit of the motor and the refrigerating system is disconnected.

[0028] The beverage manufacturing machine of the utility model is characterized in that: the beverage in the material cylinder is condensed into ice on the surface of the evaporator by the evaporator, the ice condensed on the surface of the evaporator is scraped down by the motor rotating with the reamer; the motor rotates with the reamer at a slow rotating speed in the initial stage of ice beverage preparation; the signal collector collects the data of the working condition of the beverage manufacturing machine; the controller controls the motor to change the rotating speed of the reamer according to the change of the data collected by the signal collector. Accordingly, the rotating speed of the reamer can be changed according to the data change of the working condition of the beverage manufacturing machine, so that the ice beverage can be quickly prepared and kept in a suitable state. Moreover, the risk of excessive load of the motor and damage of the motor can be avoided. BRIEF DESCRIPTION OF DRAWINGS

Among them, the directions of "upper" and "lower", "left" and "right", "front" and "rear" are opposite.

[0046] The utility model will be described in detail below in combination with specific embodiments and drawings.

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

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

[0049] The stirring power device comprises a motor 310 and a transmission shaft 320 driven by the motor 310, the motor 310 is located in the body 100, the transmission shaft 320 is coaxially arranged in the center of the evaporator 210, and 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 sleeved 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 driving of the motor, and the ice food condensed on the surface of the evaporator is scraped into slush and stirred to be 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 is detachably sleeved on the evaporator 210 and the reamer 400 through the through hole of the rear end of the barrel, 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 part of the rear end of the barrel 500 in contact with the body is sealed, such as the sealing ring 501 arranged here, when the barrel is assembled in place, the sealing ring 501 is pressed to achieve sealing. In order to maintain the sealing, when the barrel is installed in place, the barrel is locked by the locking pin 120 or other locking structures as shown. The rear end of the top of the barrel 500 is provided with a feeding opening 502 for feeding the barrel, and the front end of the bottom of the barrel 500 is provided with an openable and closable discharging opening 503. Generally, a valve 504 is arranged for the discharging opening, and the discharging opening is opened or closed through the valve.

[0052] The beverage maker, as shown in the figure, comprises a signal collector and a controller 700. The signal collector is used to collect data of the working condition of the beverage maker. The controller controls the rotating speed of the motor according to the data collected by the signal collector. Accordingly, the beverage maker can change the rotating speed of the reamer according to the data of the working condition, so as to quickly prepare ice drinks and keep the ice drinks in a suitable state. Figure 6

[0053] Specifically, the signal collector comprises a temperature sensor 610, and the controller 700 controls the rotating 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, directly reflect the state of the beverage, and is beneficial to control the ice drinks in the ideal state.

[0054] As shown in the figure, Figure 4 , Figure 5 ​​As shown, the temperature sensor 610 is sealed and mounted on the front end face 212 of the evaporator 210 and protrudes from the inner cavity of the feed cylinder 500, preventing beverage from leaking into the evaporator. Furthermore, the temperature sensor collects the actual temperature of the cooled beverage, not the temperature of the freshly added raw material, resulting in a more accurate signal that truly reflects the temperature of the chilled beverage discharged from the outlet. Moreover, placing the temperature sensor on the front end face of the evaporator avoids interference with the rotation of the reamer.

[0055] In this beverage making machine, the front end face 212 of the evaporator 210 is equipped with a bearing housing 211. The drive shaft 320 is rotatably mounted on the bearing housing 211 via a bearing. The bearing housing 211 protrudes from the front end face 212 of the evaporator. The temperature sensor 610 is lower than the bearing housing 211 along the axial direction of the evaporator. This allows the temperature sensor to be immersed in the beverage, directly and accurately collecting the beverage's temperature. Furthermore, because the temperature sensor is lower than the bearing housing along the axial direction of the evaporator, interference with the rotation of the reamer can be avoided.

[0056] This beverage making machine uses a DC motor (310) and a signal acquisition unit including a motor status sensor (620). The controller (700) controls the motor speed based on the data collected by the motor status sensor. The motor's operating parameters change depending on the load. For example, when the beverage is liquid, the resistance to the shovel is low, resulting in a lower motor current, lower output power, and less heat generation. Conversely, when the beverage is a mixture of slush and liquid, the resistance to the shovel increases, leading to a higher motor current, higher output power, and greater heat generation. Therefore, the motor's operating parameters indirectly reflect the form of the iced beverage. By collecting the motor's operating data, the speed of the motor and the shovel is controlled.

[0057] This beverage making machine has a 400mm reamer. Figure 5 As shown, the evaporator 210 includes at least two stirring arms 410, which extend spirally along the cylindrical surface of the evaporator 210. The front end of the stirring arm 410 is widened to form a pushing surface 420. The inner edge of the pushing surface 420 is connected to a shaft connecting part 430, which is mounted on a drive shaft 320. The pushing surface 420 and the stirring arm 410 have a notch 440 at their adjacent points. The notch 440 has an axial edge 450, which is close to the front end face 212 of the evaporator. This ensures the fit between the reamer and the evaporator. Furthermore, as the reamer rotates, the axial edge can scrape away ice condensed on the front end face of the evaporator, preventing ice buildup from causing errors in the data collected by the temperature sensor.

[0058] like Figure 5As shown, the reamer 400 of the beverage maker comprises a support ring 460 sleeved at the rear end of the evaporator 210, at least two support rods 470 extending forward from the support ring 460 and connected with the stirring arm 410 at the intersection, and the notch 440 located at the front end of the support rod 470. In this way, the rigidity of the reamer can be increased to avoid deformation when the reamer is blocked during rotation. Moreover, the notch is located at the front end of the support rod, which can increase the rigidity of the notch.

[0059] In view of the above beverage maker, the ice drink such as slush is made by the following method:

[0060] The liquid beverage is added into the cartridge, the beverage in the cartridge is condensed into ice on the surface of the evaporator by the evaporator, and the ice condensed on the surface of the evaporator is scraped down by the reamer rotating with the motor. Moreover, the motor with the reamer rotates at a relatively slow speed in the initial stage of making the ice drink; the data of the working condition of the beverage maker is collected by the signal collector; and the motor with the reamer changes the speed according to the change of the data collected by the signal collector by the controller. In this way, the speed of the reamer can be changed according to the change of the data of the working condition of the beverage maker, which is suitable for quickly making the ice drink and keeping the ice drink in a suitable state.

[0061] In the method, the change of the data is the temperature value of the beverage and / or the working current of the motor, the speed of the motor with the reamer is increased by the controller when the temperature value of the beverage is reduced and / or the working current of the motor is increased, and the speed of the motor with the reamer is decreased by the controller when the temperature value of the beverage is increased and / or the working current of the motor is decreased.

[0062] In the initial stage of making the ice drink, the reamer rotates at a relatively fast speed, which is not conducive to the condensation of the beverage into ice on the surface of the evaporator due to the high temperature of the beverage. Therefore, the motor with the reamer rotates at a relatively slow speed in the initial stage of making the ice drink, so that the beverage contacting the surface of the evaporator has sufficient cooling time to condense into ice. After the slush is formed, the beverage temperature is reduced, and if the reamer rotates at a relatively low speed, a relatively thick ice layer will be formed on the surface of the evaporator, which is not conducive to the scraping of the reamer and will increase the load of the motor, causing damage to the motor. Therefore, the temperature value of the beverage and / or the working current of the motor is collected to control the speed of the motor, so that the slush ice drink in an ideal state is made, and the load of the motor and the risk of damage to the motor are reduced.

[0063] In the method, the refrigeration power of the evaporator is reduced by the controller when the temperature value of the beverage is reduced and / or the working current of the motor is increased, and the refrigeration power of the evaporator is increased by the controller when the temperature value of the beverage is increased and / or the working current of the motor is decreased. In this way, the liquid beverage can be quickly cooled in the initial stage of making the ice drink, and large ice blocks can be avoided in the later keeping stage.

[0064] The method is used for the beverage maker to make different ice drinks, and the user can select the corresponding function button or working mode to start the working mode of the corresponding beverage. Different varieties of beverages can be selected, and the above method is automatically executed for different varieties of beverages.

[0065] Moreover, the motor is configured with a protection means, such as real-time detection of the working temperature and working current of the motor, and the power supply circuit of the motor and refrigeration system is disconnected 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. The power supply circuit of the motor and refrigeration system can be directly disconnected by a corresponding switch such as a temperature switch and an overcurrent switch, or can be controlled by a controller to disconnect the power supply circuit of the motor and refrigeration system.

[0066] According to the above beverage maker and method, when making a beverage, the liquid beverage is added to the barrel, and the corresponding working mode is started, and the beverage in the barrel is condensed on the surface of the evaporator by the evaporator, and the ice condensed on the surface of the evaporator is scraped off by the motor with the reamer rotating. In the initial stage, the motor with the reamer rotates at a slow speed, which is a set value. At the same time, the temperature of the beverage is collected by the temperature sensor, and the working current of the motor is detected by the motor condition sensor. When the temperature value of the beverage decreases or / and the current of the motor working increases, the controller controls the motor with the reamer to increase the speed, and when the temperature value of the beverage increases or / and the current of the motor working decreases, the controller controls the motor with the reamer to decrease the speed. Moreover, when the temperature value of the beverage decreases or / and the current of the motor working increases, the controller controls the evaporator to reduce the refrigeration power, and when the temperature value of the beverage increases or / and the current of the motor working decreases, the controller controls the evaporator to increase the refrigeration power. Accordingly, the liquid beverage can be rapidly cooled in the initial stage of making ice drinks, and large ice blocks can be avoided in the later maintenance stage.

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