All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present application, and are not of specific significance per se. Thus, "module" and "component" may be used in combination.

The ice making apparatus will be described in detail with reference to fig. 2 and 3.
Fig. 2 shows a refrigeration system of an ice making apparatus, wherein the refrigeration system further comprises an ice cube preparation system and a cold water preparation system, and the compressor 1 is the power of the whole refrigeration system and is used for driving the refrigerant in the pipeline system to circulate back and forth, so that the purpose of refrigeration is achieved through cold heat exchange. The compressor works on the principle that the pressure of gas is increased by controlling and compressing the gas. The method comprises the following specific steps: the compressor sucks low-temperature low-pressure refrigerant gas from the suction pipe; the motor is operated to drive the piston or the rotor and the like to compress the piston or the rotor; the compressed high-temperature and high-pressure refrigerant gas is discharged to the exhaust pipe to provide power for the refrigeration cycle, so that the refrigeration cycle of compression, condensation (heat release), expansion and evaporation (heat absorption) is realized. The compressor is an indispensable component in the refrigeration system, and can lift low-pressure gas into high-pressure gas, which is the core of the whole system. The compressors may be classified into a volumetric type compressor and a speed type compressor according to various principles.
In an alternative embodiment, the ice cube preparation system and the cold water preparation system are heat exchanged via a plate heat exchanger 2.
As shown in fig. 2, the refrigeration system is divided into two parts by the plate heat exchanger 2, the left side is an ice block preparation system, and the right side is a cold water preparation system, and the two parts exchange heat through the plate heat exchanger 2. The plate heat exchanger is a high-efficiency heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes. Thin rectangular channels are formed between the various plates through which heat is exchanged. The plate heat exchanger is ideal equipment for liquid-liquid and liquid-vapor heat exchange. The heat exchanger has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small occupied area, wide application, long service life and the like. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, and the occupied area is one third of that of the tubular heat exchanger.
In an alternative embodiment, as shown in fig. 2, the ice cube preparation system comprises a condenser 3, a condensing fan 4, a dry filter 5, a first capillary tube 6 and a first evaporator 7, wherein:
the inlet of the condenser 3 is connected with the outlet of the compressor 1, and is used for receiving the high-temperature and high-pressure refrigerant gas compressed by the compressor 1 and condensing the high-temperature and high-pressure refrigerant gas;
the condensing fan 4 is arranged at one side of the condenser 3, and the air outlet direction of the condensing fan 4 is opposite to the condenser 3 and is used for condensing and radiating the high-temperature high-pressure refrigerant gas;
the drying filter 5 is arranged at one side of the outlet of the condenser 3 and is used for filtering moisture and impurities from the condensed and radiated low-temperature high-pressure refrigerant liquid;
the first capillary tube 6 is connected with the drying filter 5 and is used for carrying out flow limiting and depressurization on the filtered low-temperature high-pressure refrigerant liquid to obtain low-temperature low-pressure refrigerant liquid;
the inlet of the first evaporator 7 is connected with the first capillary tube 6, and the outlet is connected with the inlet of the compressor 1 through the plate heat exchanger 2, so as to evaporate the low-temperature low-pressure refrigerant liquid to take away heat.
In the embodiment of the present application, the filter drier 5 at the outlet of the condenser 3 is used for filtering impurities such as scale, welding slag, etc. possibly existing in the refrigeration system, and absorbing moisture existing in the refrigeration system. When operating at 0 ℃, if the water in the condenser is not absorbed and discharged in time, it may cause an "ice plug" to form at the throttle valve, affecting the liquid supply of the refrigeration system, and possibly even causing decomposition of the refrigerant, corrosion of metals, generation of dirt, and emulsification of the lubricating oil. Therefore, the drying filter is arranged behind the condenser, so that the problems can be avoided, and the influence on the refrigerating effect and the service life of the unit is reduced.
In the embodiment of the present application, the first capillary tube 6 at the inlet of the first evaporator 7 mainly has the functions of throttling, reducing pressure and adjusting flow rate. The high-temperature and high-pressure gas discharged from the compressor 1 is condensed and radiated by the condenser 3 to become low-temperature and high-pressure liquid, impurities in the system are filtered out by the dry filter 5, and the low-temperature and low-pressure liquid is obtained by the flow-limiting and pressure-reducing of the first capillary tube 6. The low-temperature low-pressure liquid evaporates in the first evaporator 7 (absorbs heat to take away heat in the refrigerator) to become low-temperature low-pressure gas, and then is compressed into high-temperature high-pressure gas through the compressor 1 to form circulation. The first capillary tube 6 also has a function of preventing wet compression and liquid impact and abnormal overheating.
In an alternative embodiment, as shown in fig. 2, the ice cube preparing system further includes a first bulb 8 and a second bulb 9, the first bulb 8 is disposed at an inlet side of the first evaporator 7 and is used for detecting a surface temperature of the first evaporator 7, the second bulb 9 is disposed at an outlet side of the first evaporator 7 and is used for detecting a gaseous temperature after evaporation of the refrigerant, and the surface temperature of the first evaporator 7 and the gaseous temperature after evaporation of the refrigerant are used as judging conditions to enable a controller to control the compressor 1 to start or stop.
As shown in fig. 2, the first bulb 8 at the inlet of the first evaporator 7 is closely adjacent to the first evaporator 7, and when the temperature of the surface of the first evaporator 7 is lower than a set temperature, the compressor 1 is started, and the refrigerant starts to circulate, thereby lowering the temperature of the ice making area. When the temperature of the surface of the first evaporator 7 reaches or exceeds the set temperature, the compressor 1 is stopped and the temperature of the ice making area is increased. The second bulb 9 at the outlet of the first evaporator 7 detects the gaseous temperature of the refrigerant after the refrigerant starts to circulate, and if the gaseous temperature of the refrigerant is lower than the set temperature, the compressor 1 continues to operate and the refrigerant continues to circulate. If the gaseous temperature of the refrigerant is higher than the set temperature, the compressor 1 is stopped and the circulation of the refrigerant is stopped.
In an alternative embodiment, as shown in fig. 2, the ice cube preparing system further comprises a first electromagnetic valve 10, the first electromagnetic valve 10 is disposed between the outlet of the compressor 1 and the inlet of the first evaporator 7, and the first electromagnetic valve 10 is used for controlling the flow direction of the refrigerant.
As shown in fig. 2, the first solenoid valve 10 may control the flow direction of the refrigerant between the compressor 1, the condenser 3, an expansion valve (not shown in the drawing), and the first evaporator 7, thereby implementing a refrigeration cycle. When refrigeration is required, the first solenoid valve 10 is opened, and the refrigerant flows from the compressor 1 to the condenser 3, and then passes through the expansion valve and the first evaporator 7 to complete the refrigeration cycle. When it is necessary to stop the cooling, the first solenoid valve 10 is closed, and the flow of the refrigerant is stopped, thereby stopping the cooling. In addition, the first solenoid valve 10 has a function of controlling the amount of refrigerant. When cooling is required, the first solenoid valve 10 is opened, and the flow rate of the refrigerant is increased, thereby improving the cooling effect. When it is necessary to stop the cooling, the first solenoid valve 10 is closed, and the flow rate of the refrigerant is reduced, thereby reducing the cooling effect.
The above is an ice cube preparation system, and a cold water preparation system is described below.
In an alternative embodiment, as shown in fig. 2, the cold water preparing system includes a second solenoid valve 11, a second capillary tube 12, a second evaporator 13, a cold water tank 14, and a circulation pump 15, wherein:

the second capillary tube 12 is connected to the outlet of the second evaporator 13, and is connected to the second electromagnetic valve 11 via the plate heat exchanger 2, for controlling the flow rate and pressure of the refrigerant, so as to promote the heat exchange between the refrigerant and the ice making system, so as to realize a refrigeration cycle.
In the embodiment of the present application, the circulating pump 15 disposed at the inlet of the second evaporator 13 mainly has the following effects: providing a liquid circulation: the circulation pump 15 circulates and conveys the refrigerant in the second evaporator 13 through a pipe system, so that the refrigerant can continuously flow, and a refrigeration cycle is formed.

In the embodiment of the present application, the actual water temperature and the actual water level in the cold water tank 14 are the judging conditions for the cold water preparation system to assist the ice making system in making ice, which will be described below.
In an alternative embodiment, the ice making apparatus further comprises a controller and a circulating water system, wherein:
