[0032] Figure 3 1 is a flowchart of a refrigerator control method according to an embodiment of the present invention. DETAILED DESCRIPTION

[0033] The present invention will be described in detail below in conjunction with 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 a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0034] In one embodiment of the present invention, a refrigeration appliance is provided. The refrigeration appliance may be a refrigerator, a freezer, a commercial display cabinet, etc. Preferably, in this embodiment, the refrigeration appliance is a refrigerator, and the specific embodiment of the present invention is described below using a refrigerator as an example.

[0035] Reference Figure 1 and Figure 2 In this embodiment, the refrigerator 100 includes a compartment 2, a refrigeration system, an ice maker, and a water injection pipe 4. The refrigeration system supplies cold to the compartment 2. The ice maker is disposed in the compartment 2. The ice maker includes an ice mold 3. The water injection pipe 4 may include a water injection port 44 for injecting water into the ice mold 3.

[0036] The refrigeration system may include an evaporator chamber provided with an evaporator. The refrigeration system may provide cooling to the compartment 2 through the evaporator chamber in an air-cooling or direct-cooling manner.

[0037] In this embodiment, the refrigerator 100 includes a box body 1, the box body 1 has a refrigerator compartment and a freezer compartment, and the refrigerator 100 also includes a refrigerator compartment door for opening and closing the refrigerator compartment, and a freezer compartment door for opening and closing the freezer compartment. The compartment 2 refers to the freezer compartment of the refrigerator 100, the ice maker is arranged in the freezer compartment, and the refrigeration system supplies cold to the freezer compartment through the evaporator compartment in the form of air cooling or direct cooling.

[0038] In other embodiments of the present invention, the refrigerator 100 has a relatively independent ice-making chamber. The compartment 2 refers to the ice-making chamber, and the ice-making machine is arranged in the ice-making chamber. The ice-making chamber can be arranged in the box body 1, or in the refrigerator or freezer, or in the refrigerator door or freezer door. The evaporator chamber of the refrigeration system can directly supply cold to the ice-making chamber, or supply cold to the freezer, and then the freezer supplies cold to the ice-making chamber.

[0039] Reference Figure 2 In this embodiment, the refrigerator 100 may further include: a heating element 6, which is used to heat the water injection pipe 4;

[0040] a temperature sensor 5 for detecting the temperature of the water injection pipe 4 ; and a controller for communicating with the heating element 6 and the temperature sensor 5 , and for controlling the operation of the heating element 6 according to the temperature of the water injection pipe 4 detected by the temperature sensor 5 .

[0041] The heating element 6 can be arranged on the water injection pipe 4. Preferably, in this embodiment, the heating element 6 is a heating wire. The heating wire can be directly coiled and arranged outside the water injection pipe 4. A sleeve can also be arranged outside the water injection pipe 4, and the heating wire can be arranged on the sleeve. Aluminum foil can also be arranged between the heating element 6 and the water injection pipe 4, so that the heating element 6 can heat the water injection pipe 4 more quickly and evenly.

[0042] The temperature sensor 5 can be arranged on the water injection pipe 4. The controller can control the temperature sensor 5 to detect the temperature of the water injection pipe 4 in real time, or control the temperature sensor 5 to start and detect the temperature of the water injection pipe 4 after receiving a specific signal, such as receiving a signal to start the ice maker.

[0043] By detecting the temperature of the water injection pipe 4 through the temperature sensor 5, the controller can more accurately control the operation of the heating element 6. For example, if the temperature sensor 5 detects that the temperature of the water injection pipe 4 is lower than 0°C, it indicates that ice may form in the water injection pipe 4, and the controller can control the heating element 6 to start heating the water injection pipe 4. Such an arrangement can reduce energy loss and extend the service life of the heating element 6 while achieving effective ice melting in the water injection pipe 4.

[0044] Preferably, in this embodiment, the controller is also used to: when the temperature sensor 5 detects that the temperature of the water injection pipe 4 is lower than 0°C, control the heating element 6 to turn on, and after the heating element 6 is turned on, when the temperature sensor 5 detects that the temperature of the water injection pipe 4 is higher than a predetermined temperature, control the heating element 6 to turn off. The predetermined temperature at which the heating element 6 is turned off can be determined by experiments or other means. With such a configuration, it is possible to control the turning on and off of the heating element 6 according to the actual temperature of the water injection pipe 4, and accurately control the temperature node at which the heating element 6 is turned on and the temperature node at which it is turned off.

[0045] In other embodiments of the present invention, after the controller controls the heating element 6 to turn on according to the temperature of the water injection pipe 4 detected by the temperature sensor 5, the controller can also start the timing at the same time to calculate the cumulative turning-on time of the heating element 6. When the heating element 6 is turned on for a preset time, the heating element 6 is controlled to turn off.

[0046] Reference Figure 2 Further, in this embodiment, the water injection pipe 4 includes an adjacent first section 41 and a second section 42. The first section 41 is a section of the water injection pipe 4 at a first distance from the water injection port 44. The second section 42 is a section of the water injection pipe 4 at a second distance from the water injection port 44. The second distance is greater than the first distance. The heating element 6 includes a first heating element 61 and a second heating element 62. The first heating element 61 is used to heat the first section 41. The second heating element 62 is used to heat the second section 42. The temperature sensor 5 includes a first temperature sensor 51 and a second temperature sensor 52. The first temperature sensor 51 is used to detect the temperature of the first section 41. The second temperature sensor 52 is used to detect the temperature of the second section 42.

[0047] The controller is used for: when the first temperature sensor 51 detects that the temperature of the first section 41 is lower than 0°C, controlling the first heating element 61 to turn on; after the first heating element 61 is turned on, when the first temperature sensor 51 detects that the temperature of the water injection pipe 4 is higher than a first predetermined temperature, controlling the first heating element 61 to turn off; when the second temperature sensor 52 detects that the temperature of the second section 42 is lower than 0°C, controlling the second heating element 62 to turn on; after the second heating element 62 is turned on, when the second temperature sensor 52 detects that the temperature of the water injection pipe 4 is higher than a second predetermined temperature, controlling the second heating element 62 to turn off.

[0048] Such an arrangement can realize independent heating control of different sections of the water injection pipe 4, and control the opening and closing of the corresponding heating element 6 according to the actual temperature conditions of the different sections of the water injection pipe 4. It can reduce energy loss and extend the service life of the heating element 6 while realizing effective ice melting in the water injection pipe 4.

[0049] Preferably, the first distance is 0-60 mm, and the second distance is 60-160 mm. After the water injection pipe 4 is filled with water, due to the internal pressure of the water injection pipe 4, the residual water in the water injection pipe 4 is often not easy to gather at the water injection port 44, but is easy to gather at a certain distance from the water injection port 44. Therefore, the second section 42 farther from the water injection port 44 generally has a higher probability of freezing and a more serious freezing situation than the first section 41 closest to the water injection port 44. Therefore, the second heating element 62 needs to generate more heat than the first heating element 61 to ensure that the ice in the second section 42 melts.

[0050] Preferably, in this embodiment, the second predetermined temperature is higher than the first predetermined temperature. Preferably, the first predetermined temperature is 60°C. The second predetermined temperature is 120°C. In this way, the second heating element 62 can heat the water injection pipe 4 to a higher temperature, so that the second heating element 62 can generate enough heat to ensure that the ice in the second section 42 of the water injection pipe 4 is fully melted.

[0051] Furthermore, in this embodiment, the controller is also used to control the first heating element 61 to be turned on at a first power, and control the second heating element 62 to be turned on at a second power, wherein the second power is greater than the first power. Preferably, the first power is 5W. The second power is 7W. In this way, the second heating element 62 can heat the water injection pipe 4 with a greater heating power, so that the second heating element 62 can generate enough heat to ensure that the ice at the second section 42 of the water injection pipe 4 is fully melted.

[0052] Reference Figure 2 , Further, in this embodiment, the water injection pipe 4 also includes a third section 43, the third section 43 is adjacent to the second section 42, the third section 43 is a section of the water injection pipe 4 at a third distance from the water injection port 44, the third distance is greater than the second distance, an insulation layer 7 is provided outside the compartment 2, the first section 41 is at least partially located in the compartment 2, the third section 43 is placed in the insulation layer 7, the heating element 6 also includes a third heating element 63, and the temperature sensor 5 also includes a third temperature sensor,

[0053] The controller is used to: when the third temperature sensor 53 detects that the temperature of the third section 43 is lower than 0°C, control the third heating element 63 to turn on; after the third heating element 63 is turned on, when the third temperature sensor 53 detects that the temperature of the water injection pipe 4 is higher than the third predetermined temperature, control the first heating element 61 to turn off.

[0054] Preferably, the third distance is 160-220 mm. Since the temperature in the compartment 2 is relatively low and the insulation layer 7 has a certain effect of isolating the cold transfer, the section of the water injection pipe 4 located in the compartment 2 has a higher probability of freezing and a more serious freezing condition than the section of the water injection pipe 4 located in the insulation layer 7. Therefore, the third heating element 63 needs to generate less heat to melt the ice than the first heating element 61.

[0055] Preferably, in this embodiment, the third predetermined temperature is lower than the first predetermined temperature. Preferably, the third predetermined temperature is 40°C. In this way, the third heating element 63 can be turned off when heating the water injection pipe 4 to a temperature lower than that of other heating elements 6, which can reduce energy loss and extend the service life of the heating element 6 while achieving effective ice melting of the water injection pipe 4.

[0056] Furthermore, in this embodiment, the controller is also used to control the third heating element 63 to be turned on at a third power, and the third power is lower than the first power. Preferably, the third power is 3W. In this way, the third heating element 63 can heat the water injection pipe 4 at a relatively small heating power, and can reduce energy loss and extend the service life of the heating element 6 while achieving effective ice melting of the water injection pipe 4.

[0057] Reference Figure 2 and Figure 3 In this embodiment, a control method of the refrigerator 100 is also provided, which includes:

[0058] Obtaining a water injection signal for injecting water into an ice mold 3 of an ice maker;

[0059] When the water injection signal is obtained, it is detected whether the temperature of the water injection pipe 4 is lower than the preset temperature, and the water injection pipe 4 is used to inject water into the ice mold 3;

[0060] If so, the water injection pipe 4 is heated.

[0061] Furthermore, in this embodiment, the control method of the refrigerator 100 further includes: if not, injecting water into the ice mold 3 through the water injection pipe 4.

[0062] In this embodiment, the preset temperature in "detecting whether the temperature of the water injection pipe 4 is lower than the preset temperature" can be 0°C, or a temperature higher than 0°C, such as 1°C. After the water injection signal to the ice maker is obtained, the temperature sensor 5 is started to detect the temperature of the water injection pipe 4. When it is detected that the temperature of the water injection pipe 4 is lower than the preset temperature, it indicates that the water injection pipe 4 may be frozen, and then the heating element 6 is started to heat the water injection pipe 4. In this way, the operation of the heating element 6 can be controlled more accurately, and the energy loss can be reduced while the water injection pipe 4 is effectively thawed, thereby extending the service life of the heating element 6.

[0063] If it is detected that the temperature of the water injection pipe 4 is not lower than the preset temperature, it indicates that the water injection pipe 4 has not reached the freezing temperature, and ice cannot form in the water injection pipe 4. Therefore, it is unnecessary to heat the water injection pipe 4, and water can be injected into the ice mold 3 through the water injection pipe 4. In this way, the operation of the heating element 6 can be controlled more accurately, and the heating element 6 can be prevented from being started unnecessarily.

[0064] Reference Figure 2 Furthermore, in this embodiment, the control method of the refrigerator 100 further includes:

[0065] Detecting whether the temperature of the water injection pipe 4 is higher than a preset temperature;

[0066] If so, stop heating the water injection pipe 4.

[0067] The preset temperature in “detecting whether the temperature of the water injection pipe 4 is higher than the preset temperature” can be determined by experiments, etc. In this way, the temperature node at which the heating element 6 is turned off can be accurately controlled, and energy loss can be reduced while effectively melting ice in the water injection pipe 4.

[0068] Reference Figure 2 Furthermore, in this embodiment, the control method of the refrigerator 100 further includes:

[0069] After the heating of the water injection pipe 4 is stopped, water is injected into the ice mold 3 through the water injection pipe 4 .

[0070] That is, after heating is completed, even if there is ice in the water injection pipe 4, it has been fully melted, and water can be injected into the ice mold 3 through the water injection pipe 4, which can effectively avoid the water injection pipe 4 from being blocked by ice and ensure the water injection into the ice mold 3.

[0071] Furthermore, in the present invention, a computer-readable storage medium is also provided, on which a computer program is stored, wherein when the computer program is executed by a processor, the steps in the control method of the refrigerator 100 described in any of the above embodiments are implemented.

[0072] In summary, the refrigeration appliance, the control method of the refrigeration appliance and the storage medium of the present invention can solve the problem in the prior art that the water in the water injection pipe 4 is easy to freeze, resulting in the blockage of the water injection pipe 4 and the inability to inject water into the ice maker. The technical solution of the present application can accurately control the operation of the heating element 6, and while effectively melting ice in the water injection pipe 4, reduce energy loss and extend the service life of the heating element 6.
