[0038] Hereinafter, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0039] As shown in Figure 1 , Figure 2 The embodiment of the present application provides an ice maker, comprising:

[0040] A compressor refrigeration system;

[0041] A water supply system;

[0042] An ice making system connected with the compressor refrigeration system and the water supply system, used for cooperating with the compressor refrigeration system and the water supply system to make ice;

[0043] A control system connected with the compressor refrigeration system, the water supply system and the ice making system, used for controlling the operation thereof;

[0044] The control system comprises a controller 5 and a temperature sensor 1, the temperature sensor 1 is arranged in the ice making system, used for sensing the ice making temperature in the ice making system, so that the controller 5 can judge whether the ice making system is frozen based on the ice making temperature.

[0045] Continuing to combine Figure 1 and Figure 2 The compressor refrigeration system comprises an evaporating pipe 2, and the evaporating pipe 2 is connected with an ice making assembly in the ice making system.

[0046] Specifically, the ice making assembly in the embodiment comprises an ice making bucket 3, and the evaporating pipe 2 is wound outside the ice making bucket 3. The temperature sensor 1 is arranged on the evaporating pipe 2.

[0047] As shown in Figure 2As shown, the inlet side of the evaporation tube 2 is located below the ice bucket 3, and the outlet side is located above the ice bucket 3. The temperature sensor 1 is arranged at a position adjacent to the inlet side of the evaporation tube 2, and can also be arranged at other positions below the evaporation tube 2.

[0048] When installing the temperature sensor 1, in this embodiment, it is fixed within the ice-making system using aluminum foil. Furthermore, an insulation assembly is provided over the ice bucket 3, evaporator tube 2, and temperature sensor 1. This insulation assembly includes an insulation cover 4, with an annular spacer forming an insulation layer between the insulation cover 4, the evaporator tube 2, and the temperature sensor 1. This annular spacer is filled with a foam material for insulation.

[0049] In practical application, combined with Figure 1 、 Figure 2 and Figure 3 As shown, the temperature sensor 1 is located in the ice bucket 3 of the refrigeration system. It is secured to the lower portion of the evaporator tube 2 wrapped around the refrigeration bucket using aluminum foil (i.e., near the evaporator inlet). This location is unique in that it can quickly detect signs of freezing in the ice bucket 3 and is the most direct indicator of temperature changes in the system. Furthermore, by using aluminum foil to mount the temperature sensor 1, the temperature sensor 1 can accurately read the temperature of the ice bucket 3 despite the cold-resistant and flame-retardant properties of aluminum foil. Furthermore, by securing the temperature sensor 1 to the refrigeration bucket and then assembling it with an insulation cover 4 over the ice bucket 3, evaporator tube 2, and temperature sensor 1, and injecting insulation material into the insulation cover 4, the ice bucket 3, and the evaporator tube 2 for foam protection, the accuracy of the collected temperature value can be more effectively ensured to be unaffected by external temperature fluctuations, preventing the controller 5 from misjudging or misinterpreting the collected temperature value based on inaccurately collected temperature values. Furthermore, the provision of this insulation assembly also serves as a secondary fixation for the temperature sensor 1 and other structural components.

[0050] Furthermore, the compressor refrigeration system also includes a compressor and a fan, the ice-making system includes an ice bucket 3, an ice scraper, and an ice squeezer, and the water supply system includes a water pump. When the control system determines that the ice-making system has a risk of freezing based on the temperature data sensed by the temperature sensor 1, the compressor and the fan are controlled to stop running, and the water pump is controlled to run at the same time to output normal temperature water to the ice bucket 3 to flush and heat the ice bucket 3 to prevent the ice bucket 3 from freezing.

[0051] For example, Figure 3 As shown, the controller 5 is provided with an interface 6 for connecting the temperature sensor 1. The temperature sensor 1 can be connected to the controller 5 through the interface 6 to upload the temperature collection data to the controller 5 in real time. Figure 4As shown, after the compressor is started for X minutes, the temperature sensor 1 starts to collect the temperature in X minutes and uploads to the controller 5, the controller 5 generates a first sensing signal T1 after taking the average of the temperature, if T1≥t℃, the controller 5 generates a second sensing signal T2 after taking the average of the temperature value collected by the temperature sensor 1 in X+1 minutes, and generates a third sensing signal T3 after taking the average of the temperature collected in X+2 minutes. The controller 5 enters the comparison process of the set anti-freezing threshold M1, M2 after analyzing and determining according to the first sensing signal, after comparison, if T1-T2≥M1 and T2-T3≥M2, the controller 5 controls to stop the compressor refrigeration to avoid further temperature reduction causing the ice making bucket 3 to freeze. If T1<t℃, the controller 5 generates fourth and fifth sensing signals T4, T5, and enters the set anti-freezing threshold M3 after determining according to the first sensing signal, any temperature value T4, T5 in two minutes satisfies T4-T5≥M3, the controller 5 controls to stop the compressor refrigeration to avoid further temperature reduction causing freezing. For example, after the temperature reaches the anti-freezing threshold, the controller 5 quickly stops the refrigeration system (the compressor and the fan stop running), starts the water supply system (the water pump continuously runs) to cool the ice making system, and continuously flushes the ice making system at room temperature through the heat exchange to increase the temperature, thereby playing a role in predicting freezing.

[0052] Based on the disclosure of each of the above embodiments, the water dispenser in the embodiment can make the temperature sensor 1 more quickly and accurately collect the ice making temperature of the ice making system by setting the temperature sensor 1 to be fixed at a lower position of the evaporative pipe 2 wound on the ice making bucket 3, i.e. adjacent to the inlet side of the evaporative pipe 2, and setting the heat preservation assembly outside the evaporative pipe 2, the temperature sensor 1 and the ice making bucket 3, and then uploading to the controller 5, so that the controller 5 can accurately determine whether the ice making bucket 3 has a freezing risk, and can control the refrigeration system and the water supply system to cooperate to heat the ice making system when it is determined that the ice making system has a freezing risk, thereby preventing the ice making system from freezing.

[0053] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application, the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements should also be considered to fall within the protection scope of the present application.
