Description

multifunctional ice machine

technical field

The invention relates to an ice making device, in particular to a multifunctional ice making machine.

Background technique

Existing ice machines for making edible ice cubes usually include an ice making device, an ice making bucket and its driving mechanism, a liquid supply system, an ice storage device and a control system. The ice making device includes a compressor, a condenser, a cooling fan, a refrigerant filter, a restrictor (capillary), an evaporator and an ice removal solenoid valve. The storage device includes an ice bucket and a sealed door of the ice bucket. The control system includes a microcomputer controller and sensors. When making ice, the liquid is sprayed from the liquid supply system to the evaporator or flows through the evaporator, and the ice making system starts at the same time, and the evaporator conducts heat exchange to make the water condense into ice. After the set ice making time has passed, the deicing solenoid valve is energized, the surface of the ice particles melts and the mold is released, and the ice cubes can be poured into the ice storage bucket, and the ice making device will start the next ice making cycle; in the ice storage bucket, Ice pellets are stored in ice storage buckets. Existing ice machines all contact the evaporator with the outer surface of the ice-making hopper for heat exchange, and the water in the ice-making hopper condenses and freezes from the outside to the inside, and the condensation inside is often not dense enough; and when deicing, The melted ice water is still attached to the surface of the ice cube, and if it is refreezed, it is easy to condense with the adjacent ice cubes again. In addition, the existing ice machines are only suitable for making ice with clean water. If the raw material is changed to milk tea, coffee, fruit juice and other beverages with sugar, the ice particles produced are polycrystalline and loose in texture, and they are easy to disperse when deicing. Crushed, and the sugar, coffee, fruit juice and other ingredients in it are easy to precipitate when freezing, which adds a lot of difficulty to ice making. It is also very inconvenient to use because of the special smell in the beverage, such as coffee and milk tea, which are difficult to remove in the liquid supply system.

Detailed ways

As shown in Figures 1 to 2, the present invention provides a multifunctional ice maker, including an ice maker, an ice bucket and its driving mechanism, a liquid supply system, an ice storage device, and a control system.

The ice-making device includes an ice-making evaporator 10, an ice-making compressor 11, an ice-making condenser 12, an ice-making cooling fan (not shown), an ice-making filter 14, an ice-making throttle 15 and a It is used to control the deicing solenoid valve 16 that sends the high-temperature refrigerant to the ice-making evaporator 10 . Most of the ice-making device is similar to the corresponding structure of the existing ice-making machine, and the main difference between it and the ice-making device of the existing ice-making machine is that the ice-making evaporator 10 protrudes downwards from several evaporation columns 100. When making ice, the low-temperature refrigerant flows through each evaporation column 100 in order to carry out heat exchange to remove heat and freeze.

The ice-making hopper 20 is located below the ice-making evaporator 10 and is connected to a driving mechanism (not shown in the figure). The ice-making hopper 20 corresponds to the evaporation column 100 of the ice-making evaporator 10. Driven to rise, the evaporation column 100 is inserted into the middle of the corresponding ice-making bucket 20 from top to bottom to make ice. The driving mechanism includes a motor (not shown in the figure) and a lifting frame 222. The ice making bucket 20 is placed on the lifting frame 222 and the lifting frame 222 can move under the drive of the motor.

The liquid supply system includes a liquid storage barrel 30, a liquid addition barrel (not shown), a liquid supply pump 32, and a pump located below the ice making bucket 20 so as to collect the overflow liquid from the ice making bucket 20 and guide it back to the liquid storage bucket 30. Return tank 33. After the filling barrel is filled with liquid, it is installed on the corresponding filling barrel seat (not shown in the figure), and the liquid level is controlled by the liquid storage barrel. In the ice bucket 20 , the remaining liquid overflowed from the ice making bucket 20 is collected into the return flow tank 33 and finally guided back into the liquid storage barrel 30 .

The ice storage device mainly includes an ice storage bucket 40 and a refrigeration system that keeps the ice storage bucket 40 at a lower temperature. The refrigeration system includes a refrigeration compressor 411, a refrigeration condenser 412, a cooling fan 413, a refrigeration filter 414, Refrigerating throttling device 415 (capillary tube), refrigerating evaporator 416, defrosting solenoid valve (not shown in the figure), circulation fan 418 and ice bucket sealing door. Through the operation of the refrigeration system, the ice storage bucket 40 is kept at a lower temperature to facilitate the preservation of ice particles. The ice storage device and the ice storage device of the existing ice machine have the difference between refrigerated and non-refrigerated and pre-hardened.

As shown in Figure 2, the control system includes a computer controller and several sensors, and the sensors include liquid level sensors and water injection sensors in the liquid supply system. The control system part can set the ice making time, temperature and the temperature in the ice bucket. The computer controller has a time delay command to pre-harden the ice pellets.

The ice-making raw material is not limited to clean water, and can also be liquids containing nutrients such as fruit juice, milk tea, and coffee.

When making ice, firstly, the driving mechanism lifts the ice-making bucket to the bottom of the ice-making evaporator 10, so that each evaporation column 100 of the ice-making evaporator 10 is inserted into the middle of the ice-making bucket 20 from top to bottom; Supply liquid into the ice-making hopper 20, and the injected liquid surrounds the evaporation column 100; restart the ice-making device, and circulate the low-temperature refrigerant to the ice-making evaporator 10, and exchange heat with the liquid in the evaporation column 100, so that The liquid condenses into ice from the inside out; when the set ice-making time is reached, the ice-making hopper 20 will be separated from the ice-making evaporator 10 by the driving mechanism and placed aside, according to the time delay of pre-hardened ice particles After instructing to pre-harden the ice particles for a predetermined time, the deicing solenoid valve 16 acts to lead the high-temperature refrigerant to the ice-making evaporator 10, so that the ice particles fall off the evaporation column 100 and fall into the ice storage bucket 40; Then, the driving mechanism again drives the ice-making bucket 20 to move below the ice-making evaporator 10 to perform the next ice-making cycle. And the operation of the refrigeration system of the ice storage device makes the ice storage bucket 40 remain at a low temperature of minus 1 to minus 25 degrees, so that the ice particles can continue to freeze and harden in the ice storage bucket 40, which is conducive to long-term preservation.

The multi-function ice maker of the present invention can use multiple ice-making evaporators 10, for example, two ice-making evaporators 10, and two ice-making hoppers 20 and their driving mechanisms are correspondingly provided.

Since the ice-making evaporator 10 has a plurality of downwardly protruding evaporation columns 100 and can be inserted into the ice-making bucket 20, the liquid in the ice-making bucket 20 is condensed and frozen from the inside to the outside, and the ice grains are hard; The liquid produced during ice still remains in the concave hole left by the evaporation column 100 in the middle of the ice particle. Adjacent ice particles condense into one; in addition, the present invention not only can use water to make ice, but also is suitable for using liquids containing nutrients such as fruit juice, coffee, milk tea, etc. to make ice, and the prepared ice particles can continue to freeze and harden when stored at low temperature.
