Description

Beverage mixing machine

Technical Field

The present disclosure relates to the technical field of beverage dispensing machines, and in particular to a beverage dispensing machine.

Background

The stirring motor of the existing beverage mixing machine is linked with a power supply, and once the existing beverage mixing machine is powered on, stirring can be always operated. The stirring operation is to maintain the temperature of ice water in the water tank to be about 0 ℃ so as to ensure the heat exchange effect of the cooling pipeline of the beverage mixing machine. However, the heat generated during the continuous operation of stirring accelerates the melting of the ice plate, increases the energy consumption during the standby period when the beverage is not sold, and meanwhile, the continuous operation of stirring can cause the water flow to continuously wash the ice plate, which is not beneficial to maintaining the shape of the ice plate, and the long-time operation of the motor can obviously reduce the service life.

Therefore, there is a need for a beverage dispenser that at least partially solves the problems of the prior art.

In the description of the present invention, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be inferred therefrom without exceeding the requirements of the prior art, because such terms are used for descriptive purposes only and are intended to be broadly construed. The various devices, systems, and methods described herein may be used alone or in combination with other devices, systems, and methods.

The utility model discloses a beverage mixing machine.

As shown in fig. 1, in a preferred embodiment, the beverage dispenser 100 includes a water tank 10, a carbonator tank 11, a syrup bag 12, an evaporator coil 20, a refrigeration unit 30, a blending unit 40, a control unit 60, a nozzle unit 70, and a water supply unit 80. Wherein the water tank 10 is used to store water required for cooling the beverage. An evaporator coil 20 is disposed in the tank 10, the evaporator coil 20 containing a refrigerant (e.g., freon) for cooling the water in the tank 10. A refrigeration unit 30 is connected to the evaporator coil 20 for cooling the evaporator coil 20 to form an ice bank on the surface of the evaporator coil 20 to enable the water temperature in the tank 10 to approach 0 c. The stirring device 40 is used to stir the water in the water tank 10 to make the temperature of the water in the water tank 10 uniform. The carbonator tank 11 is used to store carbonated water required for preparing a beverage at normal temperature. The syrup bag 12 is used to store syrup required for preparing a beverage at an ordinary temperature. The nozzle arrangement 70 is used to release the beverage when the user is taking a cup. The water supply device 80 serves to deliver the carbonated water in the carbonator tank 11 and the syrup in the syrup bag 12 to the nozzle device 70 through the low temperature environment of the water tank 10 so that a user can obtain a low temperature brewed beverage. The control device 60 is coupled to the cooling device 30, the stirring device 40, the nozzle device 70 and the water supply device 80 to control the operations of these devices.

Specifically, the evaporator coil 20 includes a refrigerant inlet 20a and a refrigerant outlet 20 b. The refrigerant circulates in the direction of the arrows in fig. 1. The refrigeration device 30 includes a capillary throttle 31, a compressor 32, a condenser 33, and a fan 34. The compressor 32 is coupled to a control 60 and the suction line of the compressor 32 is connected to the refrigerant outlet 20b of the evaporator coil 20 for compressing the refrigerant into a high temperature, high pressure gas. The condenser 33 has one end connected to the discharge pipe of the compressor 32 and the other end connected to the capillary throttle 31. The refrigerant is formed into a high-temperature and high-pressure liquid in the condenser 33. The capillary throttle 31 includes a first end 31a and a second end 31b, wherein the first end 31a is connected to the refrigerant inlet 20a of the evaporator coil 20 and the second end 31b is connected to the condenser 33. The refrigerant passes through the capillary restriction 31 to become a low temperature and low pressure liquid and then becomes a low temperature and low pressure gas in the evaporator coil 20. Wherein the refrigerant absorbs heat from the environment as it changes from liquid to gas in the evaporator coil 20, i.e., from the water in the tank 10, causing the water in the tank 10 to drop in temperature and form an ice sheet on the outer surface of the evaporator coil 20. The fan 34 is connected to the control device 60 for dissipating heat to the condenser 33. The fan 34 is operated substantially in synchronism with the compressor 32.

The stirring device 40 includes a stirrer 41 and a stirring motor 42. Wherein an agitator 41 is provided in the water tank 10, an agitator motor 42 is coupled to the control device 60, and an output shaft of the agitator motor 42 is connected to the agitator 41 to drive the agitator 41 to operate. It will be appreciated that the agitation by the agitator 41 can make the temperature of the water in the water tank 10 uniform while facilitating the uniformity of the shape of the ice sheets.

The water feeding device 80 includes a cooling water pipe 81, a cooling pulp pipe 82, and a pumping assembly (not shown). A cooling water pipe 81 is provided in the water tank 10 for delivering carbonated water required for preparing a beverage. The water inlet 81a of the cooling water pipe 81 is connected to the carbonization tank 11. The water outlet 81b of the cooling water pipe 81 is connected to the pumping assembly. A chilled slurry tube 82 is also provided in the tank 10 for delivering syrup needed to brew the beverage. The inlet 82a of the coolant slurry pipe 82 is connected to the syrup bag 12. The water outlet 82b of the coolant paddle 82 is connected to a pumping assembly. The pumping assembly is coupled to the control device 60, with its pipe inlets connected to the water outlet 81b of the cooling water pipe 81 and to the water outlet 82b of the cooling syrup pipe 82, and its pipe outlets connected to the nozzle device 70 for pumping carbonated water and syrup to the nozzle device 70, so that the carbonated water and syrup are mixed in the nozzle device 70 to prepare the beverage. The carbonated water at normal temperature from the carbonator 11 is cooled by the water in the water tank 10 while passing through the cooling water pipe 81, and the syrup at normal temperature from the syrup bag 12 is cooled by the water in the water tank 10 while passing through the cooling syrup pipe 82, so that the beverage dispenser 100 can provide a prepared beverage at a low temperature. Generally, carbonated water is mixed with syrup in a predetermined ratio to prepare a beverage at a temperature of about 2 ℃.

As shown in fig. 1 and 2, the nozzle device 70 includes a valve 71, a push rod 72, a micro switch 73, and a nozzle 74. The push rod 72 is connected to a micro switch 73, and when the user needs to perform a cup-making operation, the push rod 72 is operated (e.g., the push rod 72 is pushed), and when the push rod 72 is operated, the micro switch 73 is closed. The microswitch 73 is coupled to the control device 60, and when the microswitch 73 is in the closed mode, the microswitch 73 sends a cup opening signal to the control device 60, so that the beverage dispenser 100 is informed of the user's need for a beverage. Thus, the push rod 72 functions for user operation to trigger a cup-out signal. The valve 74 is coupled to the control device 60. After the push rod 72 is operated, the control device 60 receives a cup-opening signal, and then the control device 60 controls the valve 71 to open to release the beverage. The beverage enters the cup via the nozzle 74. Preferably, the valve 74 is configured as a solenoid valve. Preferably, the control device 60 controls the operation of the pumping assembly upon receiving the cup beating signal.

It will be appreciated that the beverage dispenser 100 may include a plurality of syrup packs 12 to store syrups of different flavors. Accordingly, the beverage dispenser 100 includes a plurality of nozzle assemblies 70 and a plurality of watering assemblies 80 so that the beverage dispenser 100 can provide multiple flavors of brewed beverages.

As shown in fig. 1, the beverage dispenser 100 is also provided with an ice control 50. Ice control 50 is coupled to control 60. An ice maker 50 is provided in the water tank 10. An ice maker 50 is provided to the evaporator coil 20. The ice controller 50 includes at least one ice layer control terminal that can signal in an aqueous environment and cannot signal in an ice environment. The signal from the ice control terminal is used to reflect the thickness of the ice layer to which the evaporator coil 20 is attached.

Specifically, as shown in fig. 3, ice control 50 is positioned to evaporator coil 20 by bracket 21 extending obliquely from evaporator coil 20. The bracket 21 includes a bracket arm 22 that extends obliquely from the evaporator coil 20. Ice controller 50 includes a first ice layer control terminal 51, a second ice layer control terminal 52, and a common terminal 53. The first ice layer control terminal 51 can emit the first signal in the water environment and cannot emit the first signal in the ice environment. The second ice layer control terminal 52 can emit the second signal in the water environment and cannot emit the second signal in the ice environment. The common terminal 53 is used to receive the first signal and the second signal and transmit the first signal and the second signal to the control device 60. The first ice layer control terminal 51, the second ice layer control terminal 52 and the common terminal 53 are sequentially arranged on the holder arm 22. Since the bracket arm 22 extends obliquely from the evaporator coil 20, i.e., the direction of extension of the bracket arm 22 is not parallel to the direction of extension of the evaporator coil 20, different positions on the bracket arm 22 are at different distances from the evaporator coil 20. As shown in fig. 3, of the three terminals, the first ice layer control terminal 51 is closest to the evaporator coil 20, the common terminal 53 is farthest from the evaporator coil 20, the second ice layer control terminal 52 is farther from the evaporator coil 20 than the first ice layer control terminal 51, and the common terminal 53 is farther from the evaporator coil 20 than the second ice layer control terminal 52.

After the chiller 30 is activated, the refrigerant in the evaporator coil 20 continuously absorbs heat from the water in the tank 10 and forms an ice bank on the outer surface of the evaporator coil 20. As the temperature of the water in the tank 10 continues to drop with the extended operation time of the refrigerating apparatus 30, the thickness of the ice sheet on the outer surface of the coil 20 gradually increases. When the ice sheet is covered to the first ice layer control terminal 51, the first ice layer control terminal 51 is surrounded by the ice environment and cannot emit the first signal. The common terminal 53 is now unable to transmit the first signal to the control 60 so that the control 60 can know that the thickness of the ice sheet has reached (greater than or equal to) the distance (e.g., the first distance) of the first ice layer control terminal 51 from the evaporator coil 20. When the ice sheet is covered to the second ice layer control terminal 52, the second ice layer control terminal 52 is surrounded by the ice environment and cannot emit the second signal. The common terminal 53 is now unable to transmit the second signal to the control 60 so that the control 60 can know that the thickness of the ice sheet has reached (is greater than or equal to) the distance (e.g., the second distance) of the second ice layer control terminal 52 from the evaporator coil 20.

It can be understood that when the thickness of the ice layer reaches the second distance, the first ice layer control terminal 51 and the second ice layer control terminal 52 are both in an ice environment, and thus the common terminal 53 cannot receive the second signal and cannot receive the first signal at the same time.

It will be appreciated that if the control device 60 can receive the first signal, it indicates that the ice sheet thickness is less than the first distance. If the control device 60 can receive the second signal, it indicates that the thickness of the ice sheet is less than the second distance. The control device 60 may receive the second signal at the same time as the first signal.

As described above, when the control unit 60 receives the cup beating signal, the water supply unit 80 needs to pump the carbonated water and syrup at normal temperature into the water tank 10, which heats the water in the water tank 10 to melt the ice sheets (the thickness of the ice sheets is reduced).

In the present application, the beverage dispenser 100 is considered to have been provided with a conventional ice slab stock when the ice slab thickness reaches the first distance, and the beverage dispenser 100 is configured to normalize the ice slab thickness to the first distance. When the slab thickness reaches the second distance, the beverage dispenser 100 is deemed to have sufficient slab stock. The stirring device 40 is advantageous in making the shape of the ice sheet uniform so that the signals from the first ice layer control terminal 51 and the second ice layer control terminal 52 are reliable.

To solve the technical problem proposed in the background art and achieve the purpose of energy saving, the control device 60 is configured such that, after the control device 60 receives the first signal, the control device 60 controls the operation of the refrigeration device 30 and the stirring device 40. That is, when the ice sheet stock is insufficient, the refrigerating device 30 operates to refrigerate to increase the thickness of the ice sheet, while the agitating device 40 operates to make the temperature of water in the water tank 10 uniform. The control device 60 controls the operation of the refrigeration device 30, and specifically controls the operation of the compressor 32 and the fan 34. The control device 60 controls the operation of the stirring device 40, and particularly, the stirring motor 42.

The control device 60 is further configured such that the control device 60 controls the refrigeration device 30 to stop operating when the control device 60 does not receive the second signal. That is, when the ice sheet reserve is sufficiently large, the refrigeration unit 30 stops operating to save energy. At the same time, the beverage dispenser 100 also needs to ensure that the common terminal 53 is not surrounded by ice, so that the control unit 60 is always aware of the thickness of the ice sheet. Typically, the control device 60 receives the signal transmitted from the common terminal 53 at a certain sampling period, and therefore, the control device 60 is configured to control the refrigeration device 30 to stop operating when the second signal is not received within a second predetermined receiving period (e.g., 1-3 sampling periods).

The control device 60 is further configured such that, when the control device 60 receives the cup beating signal, the control device 60 controls the stirring device 40 to operate for at least a first operation period. That is, when a liquid of a normal temperature enters the water tank 10, the agitating device 40 operates to make the temperature of the water in the water tank 10 uniform, that is, to make the cooling water pipe 81 and the coolant pipe 82 sufficiently heat-exchange with the water in the water tank 10 to cool the brewed beverage. Preferably, the first operating time period is 5-40 minutes.

As the beverage dispenser 100 continues to brew and discharge the beverage, the carbonated water and syrup at the normal temperature continue to enter the water tank 10, causing the water temperature in the water tank 10 to continue to rise. At this time, the control device 60 receives the cup beating signal and controls the stirring device 40 to operate. After the stirring device 40 operates for the first operation period, the control device 60 is configured to: if the control device 60 does not receive the first signal within the first predetermined receiving time (for example, 1 to 3 sampling periods), the control device 60 controls the stirring device 40 to stop working, that is, the normal temperature liquid entering the water tank 10 does not affect the normal reserve amount of the ice plate, so that the stirring device 40 is not required to continuously work to save energy; if the control device 60 receives the first signal within the first predetermined receiving time period, the control device 60 controls the stirring device 40 to continue to operate until the control device 60 does not receive the first signal within the first predetermined receiving time period, that is, the normal temperature liquid entering the water tank 10 affects the normal storage amount of the ice sheets (if a large amount of beverages are sold), at which time the stirring device 40 operates, and the refrigerating device 30 is also activated (as described above) to increase the storage amount of the ice sheets and make the temperature of the water in the water tank 10 uniform.

The control device 60 is further configured such that when the control device 60 does not receive the first signal and does not receive the cup making signal within a first predetermined receiving time period (e.g., 1-3 sampling periods), the control device 60 controls the stirring device 40 to stop operating. That is, when the ice plate is sufficiently stored and no liquid at normal temperature enters the water tank 10, the water in the water tank 10 is almost 0 ℃, and the stirring device 40 does not need to work, so that energy can be saved.

The control device 60 is further configured to control the stirring device 40 to operate for a second operation time period when the control device 60 does not receive the cup beating signal for a third preset receiving time period. That is, during the period of no beverage being sold, the beverage dispenser 100 will start the operation of the stirring device 40 at regular time with the third preset receiving time period as a period, so as to make the water temperature in the water tank 10 uniform. Preferably, the second operating time period is 30-60 minutes. Preferably, the third preset receiving time period is 3-6 hours.

In particular use, when the beverage dispenser 100 is installed and powered on, the control unit 60 determines that the evaporator coil 20 has not formed an ice sheet based on the first ice layer control terminal 51 and the common terminal 53 of the ice control 50. At this time, the control device 60 controls the compressor 32 of the refrigeration apparatus 30, the fan 34, and the agitator motor 42 of the agitator 40 to start operating. As the refrigeration unit 30 operates, the temperature of the evaporator coil 20 gradually decreases. As the water temperature in the tank 10 is pulled below freezing, the evaporator coil 20 begins to adhere to the ice layer. When the ice layer on the ice controller 50 covers the first ice layer control terminal 51, the stirring motor 42 stops operating, and when the ice layer on the ice controller 50 covers the second ice layer control terminal 52, the control device 60 controls the compressor 32 and the fan 34 of the refrigerating device 30 to stop operating, and the primary freezing is finished.

As the beverage is sold or heat is lost, the ice layer begins to melt. When the ice layer melts on the first ice layer control terminal 51 of the ice controller 50 (i.e. the ice layer covering the terminal 51 melts), the control device 60 controls the refrigerating apparatus 30 to start running until the ice layer covers the second ice layer control terminal 52, and the control device 60 controls the compressor 32 and the fan 34 of the refrigerating apparatus 30 to stop running. The refrigeration unit 30 thus operates in cycles.

When a beverage is to be dispensed, the operator pushes the push rod 72, the microswitch 73 is closed and a cup opening signal is sent to the control device 60. At this time, the control device 60 controls the stirring motor 42 to continuously operate for 5 to 40 minutes. Thereafter, if the control device 60 determines that the ice layer has covered the first ice layer control terminal 51, the stirring motor 42 stops operating; if the control device 60 determines that the first ice layer control terminal 51 is not covered with the ice layer, the stirring motor 42 continues to operate until the first ice layer control terminal 51 is covered with the ice layer.

During the period of no beverage being sold, the control unit 60 does not sense the closure signal (cup beating signal) of the microswitch 73 for 3 to 6 hours continuously, and the control unit 60 starts the agitator motor 42 to operate for 30 to 60 minutes, agitating the water in the water tank 10, thereby ensuring the shape of the ice sheet on the evaporator coil 20.

When the first signal of the first ice layer control terminal 51 and the cup beating signal of the micro switch 73 are simultaneously inputted to the control device 60, the cup beating signal of the micro switch 73 controls the operation of the stirring motor 42, that is, the cup beating signal preferentially controls the operation of the stirring motor.
