[0028] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.
[0029] See also Figure 1 The present invention provides a refrigeration device 100, which may be a refrigerator. Refrigeration device 100 may include a housing 110, which may include a storage compartment. The storage compartment may include a freezer compartment 112. Of course, the storage compartment may also include a refrigerator compartment 111 and a temperature-changing chamber. Refrigeration device 100 may include a door 120 for opening and closing the storage compartment. Door 120 may include a freezer door for opening and closing the freezer compartment.
[0030] An ice maker and an ice storage box may be installed in the ice making chamber 113. The refrigeration device 100 may also include a water injection assembly, which may include a water injection pipe that partially extends into the ice making chamber to supply water to the ice tray. The water injection assembly may automatically supply water to the ice maker through an external water source.
[0031] In this embodiment, the refrigeration device 100 further includes a refrigeration system. The refrigeration system may include a compressor 210, an ice-making evaporator 251, and a freezing evaporator 241. The refrigeration device 100 may have a compressor compartment, and the compressor 210 may be installed in the compressor compartment. The refrigeration device 100 may also include an ice-making evaporator chamber and a freezing evaporator chamber, with the ice-making evaporator 251 disposed in the ice-making evaporator chamber and the freezing evaporator 241 disposed in the freezing evaporator chamber. The ice-making evaporator chamber may be in cold air communication with the ice-making chamber 113, and the freezing evaporator chamber may be in cold air communication with the freezing chamber 112.
[0032] In one embodiment of the present invention, the ice-making evaporator chamber can be set at any position in the refrigeration equipment 100, such as in the refrigerator compartment 111, the freezer compartment 112, or the ice-making compartment 113, and can be connected to the ice-making compartment 113 through a cold air pipe.
[0033] In this embodiment, part of the refrigerant from the compressor 210 flows through the refrigeration evaporator and then flows into the freezing evaporator 241 , and part of the refrigerant flows directly through the freezing evaporator 241 .
[0034] Specifically, the refrigerant flowing out of the compressor 210 passes through the condenser and is split through a one-inlet and multiple-outlet solenoid valve. A part of it directly enters the freezing evaporator 241 through the freezing capillary tube and then flows back to the compressor 210. A part of it passes through the ice-making capillary tube and the ice-making evaporator 251 and then flows through the freezing evaporator 241 and returns to the compressor 210.
[0035] In this embodiment, the refrigeration device 100 further includes an ice-making temperature sensor, which is used to detect the temperature in the ice-making chamber 113 and can be placed in the ice-making chamber 113 .
[0036] An embodiment of the present invention provides a water injection control method, which can be used in the above-mentioned refrigeration equipment 100.
[0037] See also Figure 2 , the water injection control method includes:
[0038] Detecting the temperature of the ice making chamber 113;
[0039] Obtaining the operating cycle T of the water injection pipe heating element of the ice maker;
[0040] Obtaining the activation rate K of the water injection pipe heater according to the temperature of the ice making chamber 113;
[0041] The water injection pipe heating element is controlled to operate cyclically with an operation cycle T. The opening time of the water injection pipe heating element in the operation cycle T is K*T, and the closing time is TK*T.
[0042] In this embodiment, the water injection pipe partially extends into the ice making chamber 113, and the water outlet of the water injection pipe is arranged above the ice making tray of the ice maker to supply water to the ice making tray. When the ice maker receives the water injection signal, the water injection device can automatically inject water into the ice making tray through the water injection pipe.
[0043] During the water filling process, the water filling can be turned on and off according to the filling time. However, due to the low temperature inside the ice-making chamber 113, the water outlet of the water filling pipe is prone to freezing, affecting water filling. If the water filling pipe is completely frozen, the ice-making process will be completely interrupted. If the water outlet of the water filling pipe is partially frozen, that is, the water outlet is blocked by ice, the water flow rate will be reduced, and the amount of water injected into the ice-making tray within the preset filling time will be reduced, resulting in smaller ice cubes, which will affect the user experience.
[0044] Therefore, the water injection pipe heating element can be installed near the water outlet of the water injection pipe. The water injection pipe can be heated by arranging the water injection pipe heating element, thereby preventing the water injection pipe from freezing.
[0045] In this embodiment, the water injection pipe heating element can have a preset operating cycle T. Within an operating cycle T, the water injection pipe heating element can be turned on for a period of time, then turned off for a period of time, and then enter the next operating cycle T, that is, turned on for a period of time, then turned off for a period of time, and so on.
[0046] In this embodiment, the activation time of the water filling pipe heater within a cycle is related to the temperature of the ice-making chamber 113. The activation rate K can increase as the temperature of the ice-making chamber 113 decreases. It is understood that the lower the temperature of the ice-making chamber 113, the greater the risk of the water filling pipe freezing. Therefore, the longer the activation time of the water filling pipe heater within an operating cycle T, the greater the risk of the water filling pipe freezing.
[0047] In this way, the technical solution of this embodiment can effectively prevent the freezing of the water injection pipe from affecting ice making, while reducing energy consumption and extending the service life of the water injection pipe heating element.
[0048] Furthermore, in one embodiment of the present invention, the water injection control method further includes:
[0049] When the water injection pipe is in the water injection state, the operation cycle of the water injection pipe heating element is T1;
[0050] When the water injection pipe is in a non-water injection state, the operation cycle of the water injection pipe heating element is T2, and T2 is greater than T1.
[0051] In this embodiment, by detecting the water injection state of the water injection pipe, when the water injection pipe is in different states, the water injection pipe heating element is controlled to operate in different operation cycles.
[0052] When the water pipe is filling, the outlet must be non-freezing, and the amount of water in the pipe is high, so the possibility of freezing is also greater. When the water pipe is not filling, less water remains at the outlet, so the possibility of freezing is lower. Even if a small area of freezing occurs, its impact on the water injection is relatively small.
[0053] Therefore, when the water injection pipe of the ice maker is in the water injection state, the operating cycle of the water injection pipe heating element is shorter than the operating cycle of the water injection pipe heating element when the water injection pipe is in the non-water injection state. In this way, in the water injection state, the time that the water injection pipe heating element is closed can be further reduced, thereby reducing the risk of freezing of the water injection pipe.
[0054] Furthermore, in one embodiment of the present invention, the water injection control method further includes:
[0055] When a defrosting signal of the ice-making evaporator 251 corresponding to the ice-making chamber 113 is received, the water injection pipe heating element is controlled to be turned off.
[0056] In this embodiment, an independent ice-making evaporator 251 may be provided in the refrigeration device 100 to cool the ice-making chamber 113. In a specific embodiment, an ice-making evaporator chamber may be provided inside the ice-making chamber 113 to install the ice-making evaporator 251. The ice-making chamber 113 is provided inside the freezer chamber 112, and an insulating partition may be provided between the ice-making chamber 113 and the freezer chamber 112.
[0057] A defrost heater is installed in the ice-making evaporator chamber. During the defrost process, the defrost heater is turned on to heat the ice-making evaporator 251 while the supply of refrigerant to the ice-making evaporator 251 is stopped. In this way, the temperature in the ice-making evaporator chamber will rise, and the temperature in the ice-making chamber 113 will also rise.
[0058] Especially when the ice-making evaporator chamber is arranged in the ice-making chamber 113, the temperature in the ice-making chamber 113 is greatly affected by the temperature in the ice-making evaporator chamber. During the defrosting process, the temperature in the ice-making chamber 113 is high. At this time, the risk of freezing of the water injection pipe is low. Therefore, turning off the water injection pipe heating element during the defrosting process can further reduce energy consumption and reduce the impact of the water injection pipe heating element on the temperature of the ice-making chamber 113.
[0059] Furthermore, in one embodiment of the present invention, the water injection control method further includes:
[0060] When the water injection end signal is received, the water injection pipe heater is controlled to run for a preset time and then shut down.
[0061] In this embodiment, within a preset time period, the water injection pipe heating element can operate in a predetermined operating cycle T. Specifically, at this time, the water injection pipe heating element is in a non-water injection state, and it can operate in an operating cycle T2.
[0062] When the water injection is completed, there is a lot of water remaining in the water injection pipe, so freezing is most likely to occur at this time.
[0063] By controlling the water injection pipe heating element to continuously heat the water injection pipe after the water injection is completed, the risk of freezing of the water injection pipe can be effectively reduced.
[0064] Furthermore, in one embodiment of the present invention, the water injection control method further includes:
[0065] When it is detected that ice making ends after a preset time, the water injection pipe heating element is controlled to turn on.
[0066] In this embodiment, the next round of ice making typically begins after ice making is complete, i.e., water supply to the ice tray begins. Because a frozen water inlet pipe significantly impacts water filling, the water inlet pipe heater can be activated in advance to heat the water inlet pipe after detecting the end of ice making after a preset time. At this point, the water inlet pipe heater can operate at a preset operating cycle T, specifically, operating cycle T2, which is the non-water filling state.
[0067] In this way, the impact of freezing of the water injection pipe can be effectively avoided, and water can be injected immediately after ice making is completed, so the ice making efficiency is higher.
[0068] In another embodiment of the present invention, the water injection control method includes:
[0069] When a water injection signal is received, the water injection pipe heater is controlled to run for a preset time and then start water injection.
[0070] In this embodiment, the water injection pipe heater is not turned on before ice making is completed, but turned on after ice making is completed. In this way, the water injection pipe is prevented from freezing during water injection and affecting the water volume.
[0071] See also Figure 3 One embodiment of the present invention further provides a refrigeration device 100, comprising a memory 202 and a processor 201, wherein the memory 202 and the processor 201 are communicatively connected via a communication bus 204. The memory 202 stores a computer program executable by the processor 201. When the processor 201 executes the computer program, the steps of the water injection control method described in the above embodiment are implemented. The refrigeration device 100 also includes a communication interface 203 connected to the communication bus 204 for communicating with other devices within the refrigeration device 100.
[0072] An embodiment of the present invention further provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of the water injection control method in the above embodiment are implemented.
[0073] To sum up, the water injection control method provided by the present invention controls the periodic opening and closing of the water injection pipe heating element according to the temperature of the ice making chamber, thereby effectively avoiding the risk of the water injection pipe freezing, while reducing the energy consumption of the water injection pipe heating element and improving its service life.
