[0075] In some embodiments, a refrigerator is provided, including a refrigerating chamber 100. A refrigerating space for storing food is formed in the refrigerating chamber 100. The refrigerator includes a refrigerating door configured to close or open the refrigerating chamber 100.

[0076] The refrigerator includes a freezing chamber 200 , in which a freezing space for storing food is formed. The refrigerator also includes a freezing door configured to close or open the freezing chamber 200 .

[0077] The refrigerating chamber 100 and the freezing chamber 200 are arranged side by side or up and down. Figure 1 and Figure 2 , the refrigerating chamber 100 is arranged above the freezing chamber 200. Figure 1 This is a structural diagram observed from the front of the refrigerator. Figure 2 This is a structural diagram viewed from the back of the refrigerator.

[0078] The refrigerator includes a foam layer 300, which is arranged between the refrigerator body and the inner container. The foam layer 300 is arranged outside the refrigerating chamber 100 and the freezing chamber 200, and the foam layer 300 reduces the heat exchange between the refrigerating chamber 100 and the freezing chamber 200 and the outside.

[0079] The refrigerator includes a refrigerant heat exchange system, which includes a compressor, an evaporator, a condenser, a throttling device, etc.

[0080] The air exchanges heat through the evaporator and becomes cold air, and the cold air flows into the refrigerating chamber 100 and the freezing chamber 200 to cool the refrigerating chamber 100 and the freezing chamber 200.

[0081] The evaporator is provided with a heating wire configured to heat the evaporator to limit frost formation on the evaporator.

[0082] The defrosting function of the refrigerator evaporator is a conventional technical means in this field and will not be elaborated in detail in this article.

[0083] The refrigerator has an ice-making module configured to provide ice cubes to a user.

[0084] The ice making module includes a water storage box. The water storage box is arranged in the refrigeration chamber 100.

[0085] The ice making module includes an ice making machine. The ice making machine is arranged in the freezing chamber 200. The water storage box is configured to provide the ice making machine with water required for making ice.

[0086] The refrigerator includes a water delivery module 400, which is configured to guide the water in the water storage box to the ice maker. Figure 3 and Figure 4 、 Figure 7 and Figure 8 . Figure 3 A cross-sectional view of a refrigerator. Figure 4 for Figure 3 A magnified view of the middle part, Figure 7 This is a structural diagram of the water delivery module 400 viewed from the top. Figure 8 This is a structural diagram of the water delivery module 400 viewed from the bottom.

[0087] The water delivery module 400 includes a pre-buried pipeline 430 . The pre-buried pipeline 430 is disposed in the foaming layer 300 .

[0088] The water delivery module 400 includes a water pipeline 440. This pipeline 440, via a pre-buried pipeline 430, is configured to direct water from the water storage box to the ice maker. The pre-buried pipeline 430 provides installation space for the water pipeline 440. In other words, the water pipeline 440, via the pre-buried pipeline 430, is installed within the foam layer 300, eliminating the need to occupy space in the refrigerator compartment 100 or freezer compartment 200, thereby enhancing thermal insulation.

[0089] Since the temperature of the freezing chamber 200 is low, when the water in the water storage box flows into the ice maker through the water pipe 440, there is a risk that the water in the pipe near the freezing chamber 200 will freeze, causing the pipe to be blocked, thereby affecting the normal water supply to the ice maker.

[0090] To solve the above technical problems, the water delivery module 400 includes an air pipeline 460. The air pipeline 460 is configured to transfer heat generated by the heating wire used to defrost the evaporator to the embedded pipeline 430 to heat the water pipeline 440, prevent the water pipeline 440 from freezing, and thus improve the ice making reliability of the ice maker.

[0091] The heat generated by the heating wire when the evaporator is defrosted is used to heat the water pipe 440, and the residual heat is utilized. No electrical components are required around the water pipe 440, and the structure is simple and reliable.

[0092] In some embodiments, one end of the air line 460 is connected to the pre-buried pipe 430, and the other end of the air line 460 is connected to the chamber 240 where the evaporator is located. The heating wire used to heat and defrost the evaporator is located in the same chamber 240 as the evaporator. When the heating wire is heated, the air temperature in the chamber 240 increases. The hot air in the chamber 240 flows into the pre-buried pipe 430 through the air line 460, thereby heating the water line 440 and preventing it from freezing.

[0093] In some embodiments, a fan (not shown) is provided in the air pipeline 460 , and the fan is used to provide gas circulation power so that the hot air in the chamber 240 flows into the embedded pipeline 430 .

[0094] In some embodiments, reference Figure 7 The air pipe 460 is a flat structure, and the width of the air pipe 460 extends along the length direction of the pre-buried pipe 430. In this way, the hot air input from the air pipe 460 into the pre-buried pipe 430 can be dispersed as quickly as possible, thereby improving the air heating efficiency in the pre-buried pipe 430 and thereby improving the heating efficiency of the water pipe 440.

[0095] In some embodiments, reference Figure 2 and Figure 5 The evaporator is arranged at the top of the freezer compartment 200, the gas pipe 460 is arranged in the foam layer 300 between the refrigeration compartment 100 and the freezer compartment 200, and the pre-buried pipe 430 has at least a partial pipe section located in the foam layer 300 between the refrigeration compartment 100 and the freezer compartment 200.

[0096] In other words, at least part of the pipeline sections of the air pipeline 460 and the pre-buried pipeline 430 are arranged in the foam layer 300 at the top of the freezer compartment 200, and the evaporator is arranged at the top of the freezer compartment 200. The pre-buried pipeline 430, the air pipeline 460 and the chamber 240 where the evaporator is located are close to each other. The air pipeline 460 is set to a short length, which can realize the diversion of hot air and make full use of the space of the foam layer 300 between the refrigeration compartment 100 and the freezer compartment 200, and the structure is compact.

[0097] In some embodiments, reference Figure 10The water pipeline 440 includes a first pipeline 410, and a first end of the first pipeline 410 is connected to the water storage box.

[0098] The water pipe 440 includes a second pipe 420, a first end of the second pipe 420 is connected to the ice maker, and a second end of the second pipe 420 is connected to the second end of the first pipe 410. The water in the water storage box flows into the ice maker through the first pipe 410 and the second pipe 420.

[0099] The water pipe 440 includes a connector 450, and the first pipe 410 and the second pipe 420 are connected by the connector 450 to achieve water communication between the first pipe 410 and the second pipe 420. The two-section structure of the water pipe 440 facilitates the disassembly and assembly of the water pipe 440.

[0100] In some embodiments, reference Figure 4 and Figure 7 The first pipeline 410 is arranged in the foam layer 300 and does not occupy the space of the refrigeration chamber 100.

[0101] The second pipeline 420 is arranged in the pre-buried pipeline 430 and does not occupy the space of the freezing chamber 200. The pre-buried pipeline 430 provides an installation space for the second pipeline 420.

[0102] In other words, the first pipeline 410 is located outside the pre-buried pipeline 430 and is directly disposed in the foam layer 300 and cannot be disassembled. The second pipeline 420 is located inside the pre-buried pipeline 430 and is removable.

[0103] The air line 460 is configured to transfer heat generated by the heating wire used to defrost the evaporator to the pre-buried pipe 430, thereby heating the second pipe 420. The first pipe 410 is located near the refrigerator compartment 100, while the second pipe 420 is located near the freezer compartment 200. This makes the second pipe 420 susceptible to ice formation. The pre-buried pipe 430 provides installation space for the second pipe 420 and also provides a hot air storage space. The hot air introduced by the air line 460 is collected in the pre-buried pipe 430, fully enveloping the second pipe 420, improving its heating efficiency and preventing ice formation.

[0104] In some embodiments, a temperature sensor is provided on the second pipe 420 , and the temperature sensor is configured to detect the temperature of the second pipe 420 .

[0105] When the temperature of the second pipeline 420 is lower than the first set temperature value, there is a risk of freezing in the second pipeline 420, and the heating wire used to defrost the evaporator is started. The heat generated by the heating wire flows into the embedded pipeline 430 through the gas pipeline 460, heating the second pipeline 420 to prevent the pipeline from freezing.

[0106] When the temperature of the second pipeline 420 is higher than the second set temperature value, the second set temperature value is greater than the first set temperature value, and there is no risk of freezing in the second pipeline 420, the heating wire used to defrost the evaporator is turned off, and heating of the second pipeline 420 is stopped.

[0107] In some embodiments, when the heating wire works for a first set time, the heating wire automatically turns off and stops heating the second pipe 420 .

[0108] In some embodiments, the second pipeline 420 is detachably disposed within the pre-buried pipeline 430. The detachable configuration of the second pipeline 420 facilitates disassembly and maintenance of the second pipeline 420.

[0109] In some embodiments, reference Figure 5 and Figure 15 The second pipe 420 is configured to be installed and removed through the inner side of the freezing chamber 200. In other words, the second pipe 420 is installed into the pre-buried pipe 430 from the inside of the freezing chamber 200, or the second pipe 420 is taken out from the inside of the freezing chamber 200.

[0110] In some embodiments, the first pipe 410 is a plastic pipe. The plastic pipe is disposed in the foam layer 300 and is non-detachable. The plastic pipe has a good heat preservation effect, does not freeze, and does not occupy space in the refrigeration chamber 100.

[0111] The pre-buried pipe 430 is a plastic pipe. The pre-buried pipe 430 is arranged in the foam layer 300 and cannot be disassembled. It has a good heat preservation effect and does not occupy the space of the refrigerator compartment 100 and the freezer compartment 200.

[0112] The second pipeline 420 is a metal pipe. The metal pipe has good thermal conductivity and is highly reliable in preventing the second pipeline 420 from freezing.

[0113] In some embodiments, reference Figure 4 and Figure 10 The water delivery module 400 also includes a connector 450, which is arranged at one end of the pre-buried pipeline 430. A through hole is provided in the connector 450, and the second end of the first pipeline 410 is inserted into the through hole. The second end of the second pipeline 420 is inserted into the through hole.

[0114] The connecting piece 450 is an outsourced part and is a pipe joint. The first pipe 410 and the second pipe 420 are connected via the connecting piece 450 .

[0115] In some embodiments, reference Figure 4 and Figure 10 The connecting piece 450 includes a first joint 451 . One end of the first pipeline 410 is inserted into the first joint 451 to fix the first pipeline 410 and the connecting piece 450 .

[0117] The connecting member 450 includes a connecting pipe section 453. The connecting pipe section 453 is provided between the first connector 451 and the second connector 452 to achieve water communication between the first pipeline 410 and the second pipeline 420.

[0118] In some embodiments, the outer diameter of the first joint 451 is greater than the outer diameter of the connecting pipe section 453 , and the outer diameter of the second joint 452 is greater than the outer diameter of the connecting pipe section 453 .

[0119] Reference Figures 7 to 9 The pre-buried pipeline 430 is provided with an extension pipe section 431 on one end where the connector 450 is provided. The extension pipe section 431 is located at the outer end side of the pre-buried pipeline 430 and extends toward the direction close to the first pipeline 410.

[0120] The connecting pipe section 453 passes through the inner cavity of the extension pipe section 431. The connecting pipe section 453 is interference-fitted with the inner cavity of the extension pipe section 431. The first connector 451 is located at one end of the extension pipe section 431 and is located outside the embedded pipeline 430. The second connector 452 is located at the opposite end of the extension pipe section 431 and is located inside the embedded pipeline 430.

[0121] The extended pipe section 431 is limited between the first joint 451 and the second joint 452 , and the connecting piece 450 is fixed to the end of the embedded pipeline 430 .

[0122] In some embodiments, reference Figure 9 The pre-buried pipeline 430 is provided with a notch 432 on one end where the connector 450 is provided. A shielding portion 433 is provided at the notch 432 . The shielding portion 433 is connected to the pipe wall of the pre-buried pipeline 430 .

[0123] When installing the connecting piece 450, first remove the shielding part 433 from the embedded pipeline 430, place the connecting piece 450 into the embedded pipeline 430 through the notch 432, and the connecting pipe section 453 is located in the inner cavity of the extension pipe section 431. The first joint 451 is located outside the embedded pipeline 430, and the second joint 452 is located inside the embedded pipeline 430. Then, fix the shielding part 433 to the pipe wall of the embedded pipeline 430 to limit the connecting piece 450 and realize the fixed installation of the connecting piece 450 on the embedded pipeline 430.

[0124] In some embodiments, reference Figure 8 The shielding portion 433 constitutes a part of the side wall of the embedded pipeline 430. The shielding portion 433 is fixed by means of buckles, bonding, etc.
