Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art

[0002] A refrigerator consists of a refrigerator compartment and a freezer compartment, with the refrigerator compartment's temperature lower than the freezer's. Refrigerators with ice-making functions also include a water storage box and an ice maker, with the water storage box located in the refrigerator compartment and the ice maker located in the freezer compartment. Water in the water storage box flows through pipes to the ice maker, providing the ice maker with the water it needs to make ice. However, due to the lower temperature in the freezer compartment, water in the pipes near the freezer compartment can freeze, causing blockages and disrupting the ice maker's water supply.

[0003] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Summary of the Invention

[0004] In view of the problems pointed out in the background technology, the present invention provides a refrigerator to prevent the water in the pipeline between the water storage box and the ice maker from freezing.

[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 reduces heat exchange between the refrigerating chamber 100, the freezing chamber 200 and the outside world.

[0079] The refrigerator has an ice-making module configured to provide ice cubes to a user.

[0080] The ice making module includes a water storage box. The water storage box is arranged in the refrigeration chamber 100.

[0081] 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.

[0082] The refrigerator includes a water delivery module 400, which is configured to guide the water in the water storage box to the ice maker. Figures 3 to 8 . Figure 3 A cross-sectional view of a refrigerator. Figure 4 for Figure 3 A magnified view of the middle part, Figure 5 is a structural diagram of the water delivery module 400. Figure 6 This is a structural diagram of the water delivery module 400 viewed from the bottom side. Figure 7 is a cross-sectional view of the water delivery module 400. Figure 8 This is a structural diagram of the water delivery module 400 without omitting the pre-buried pipeline 430 .

[0083] The water delivery module 400 includes a pre-buried pipeline 430 . The pre-buried pipeline 430 is disposed in the foaming layer 300 .

[0084] The water delivery module 400 includes a pipeline 460. This pipeline 460 is located within the pre-buried pipeline 430, eliminating the need for space in the refrigerator compartment 100 or freezer compartment 200. The pipeline 460 within the foam layer 300 is located within the pre-buried pipeline 430, providing excellent insulation. The pre-buried pipeline 430 provides space for the installation of the pipeline 460.

[0085] A first end of the pipeline 460 is connected to the water storage box, and a second end of the pipeline 460 is connected to the ice maker. The water in the water storage box flows into the ice maker through the pipeline 460.

[0086] 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 pipe 460, 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.

[0087] To address the aforementioned technical issues, water delivery module 400 includes a heater 440, which is located within pre-buried pipe 430. Heater 440 is configured to heat pipe 460 to prevent freezing of pipe 460, thereby improving ice-making reliability. The pre-buried pipe provides space for heater 440.

[0088] In some embodiments, reference Figure 8 The heating element 440 is a heating wire, which is wound around the outer periphery of the pipe 460. The heating wire is energized to heat the pipe 460.

[0089] Since the pipeline 460 is close to the freezing chamber 200 and has a high risk of freezing, a heating wire is wound around at least the pipeline 460 close to the freezing chamber 200 to increase the reliability of preventing the pipeline from freezing.

[0090] In some embodiments, a temperature sensor is provided on the pipeline 460 , and the temperature sensor is configured to detect the temperature of the pipeline 460 .

[0091] When the temperature of the pipeline 460 is lower than the first set temperature value, there is a risk of freezing of the pipeline 460, and the heating wire is started to heat the pipeline 460 to prevent the pipeline 460 from freezing.

[0092] When the temperature of the pipeline 460 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 of the pipeline 460, the heating wire is turned off, and heating of the pipeline 460 is stopped.

[0093] In some embodiments, when the heating wire works for a first set time, the heating wire automatically turns off and stops heating the pipeline 460 .

[0094] In some embodiments, the first end of the embedded pipeline 430 is connected to the outer wall of the refrigerating chamber 100, and the second end of the embedded pipeline 430 is connected to the outer wall of the freezing chamber 200 to prevent the embedded pipeline 430 from moving when the refrigerator is foaming.

[0095] In some embodiments, reference Figure 4 、 Figures 5 to 7 The pre-buried pipe 430 includes a first section 431. The first section 431 is located within the foam layer 300 on the back side of the refrigeration chamber 100, with one end connected to the outer wall of the refrigeration chamber 100. The arrangement of the first section 431 fully utilizes the space on the back side of the refrigeration chamber 100, resulting in a compact structure.

[0096] A first extension portion 435 is provided at the end of the first embedded pipe section 431. The first extension portion 435 extends flatly toward the outer periphery of the end of the first embedded pipe section 431. The first extension portion 435 is fixedly connected to the outer wall of the refrigerator compartment 100, increasing the contact area with the outer wall of the refrigerator compartment 100 and improving connection reliability.

[0097] The pre-buried pipe 430 includes a second section 432. This section 432 is located within the foam layer 300 between the refrigerator compartment 100 and the freezer compartment 200. One end of the second section 432 is connected to the outer wall of the freezer compartment 200. This arrangement fully utilizes the space above the freezer compartment 200, resulting in a compact structure.

[0098] The second extension portion 436 is provided at the end of the second pre-buried pipe section 432. The second extension portion 436 extends flatly toward the outer periphery of the end of the second pre-buried pipe section 432. The second extension portion 436 is fixedly connected to the outer wall of the freezer compartment 200, increasing the contact area with the outer wall of the freezer compartment 200 and improving connection reliability.

[0099] In some embodiments, the first pre-buried pipe section 431 and the second pre-buried pipe section 432 are integrally formed. In other words, the periphery of the pre-buried pipe 430 has no gaps, thereby preventing the foaming material from entering the interior of the pre-buried pipe 430 during foaming.

[0100] In other embodiments, referring to Figure 9 Pre-buried pipeline 430 includes a first pre-buried sub-pipeline 433, which is an open structure with a first opening. Pre-buried pipeline 430 also includes a second pre-buried sub-pipeline 434, which is an open structure with a second opening. First pre-buried sub-pipeline 433 and second pre-buried sub-pipeline 434 are fastened together, with the first opening and the second opening butting against each other to form pre-buried pipeline 430.

[0101] The pre-buried pipeline 430 has a two-stage structure, which facilitates the installation of the pipeline 460. During installation, the first pre-buried sub-pipeline 433 and the second pre-buried sub-pipeline 434 are first in a separate state. For example, the pipeline 460 is installed into the first pre-buried sub-pipeline 433 through the first opening, and then the second pre-buried sub-pipeline 434 is snapped onto the first pre-buried sub-pipeline 433 to complete the installation.

[0102] In some embodiments, reference Figure 7 and Figure 8 The pipeline 460 includes a first pipeline 410. One end of the first pipeline 410 is connected to the water storage box.

[0103] The pipeline 460 includes a second pipeline 420. One end of the second pipeline 420 is connected to the ice maker. The first pipeline 410 is connected to the second pipeline 420. The water in the water storage box flows into the ice maker through the first pipeline 410 and the second pipeline 420.

[0104] In some embodiments, the first pipeline 410 and the second pipeline 420 are detachably connected, which facilitates the disassembly and maintenance of the pipeline 460.

[0105] In some embodiments, since the second pipeline 420 is close to the freezing chamber 200, a heating element 440 is provided to heat the second pipeline 420 to prevent the pipeline 460 from freezing while maintaining low energy consumption.

[0106] In some embodiments, pre-buried pipe 430 is a plastic pipe, which provides excellent thermal insulation. First pipe 410 is a plastic pipe, and second pipe 420 is a metal pipe. Metal pipes have good thermal conductivity, and heating element 440 heats the metal pipe with high thermal efficiency, thus reliably preventing second pipe 420 from freezing.

[0107] In some embodiments, reference Figure 7 and Figure 8 The water delivery module 400 also includes a connector 450, which is disposed in the pre-buried pipeline 430. A through hole is provided in the connector 450, one end of the first pipeline 410 is inserted into the through hole, and one end of the second pipeline 420 is inserted into the through hole.

[0108] 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 .

[0109] In some embodiments, reference Figure 7 and Figure 8 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 .

[0110] The connecting piece 450 includes a second joint 452 . One end of the second pipeline 420 is inserted into the second joint 452 to achieve fixation between the second pipeline 420 and the connecting piece 450 .

[0111] 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.

[0112] In some embodiments, the inner diameter of the second pre-buried pipeline section 432 is larger than the inner diameter of the first pre-buried pipeline section 431 , the first pipeline 410 is disposed in the first pre-buried pipeline section 431 , and the second pipeline 420 and the connector 450 are disposed in the second pre-buried pipeline section 432 .

[0113] The inner diameter of the second section 432 of the pre-buried pipeline is large, which provides sufficient space for the installation of the heating element 440 and the connecting element 450.

[0114] In some embodiments, reference Figure 4 The pre-buried pipeline 430 extends in an inclined posture, and the second pipeline 420 extends along the pre-buried pipeline 430. The second pipeline 420 is in an inclined posture, which is convenient for water transportation.

[0115] In some embodiments, reference Figure 4 and Figure 8The second pipeline 420 includes a second pipeline section 421, which runs obliquely along the pre-buried pipeline 430. The second pipeline section 421 constitutes the main pipeline portion of the second pipeline 420. The upper end of the second pipeline section 421 is connected to the lower end of the first pipeline 410. For example, the upper end of the second pipeline section 421 is connected to the second joint 452 of the connector 450.

[0116] The second pipeline 420 includes a second pipeline section 422, which extends downward from the lower end of the second pipeline section 421 to connect to the ice maker. The second pipeline section 422 is in a vertical position to facilitate water injection into the ice maker.

[0117] In some embodiments, reference Figure 8 The first pipeline 410 includes a first pipeline section 411, and the first pipeline section 411 extends into the refrigerating chamber 100 to be connected to the water storage box.

[0118] The first pipeline 410 includes a first pipeline second section 412 , and the first pipeline second section 412 extends at the back side of the refrigeration chamber 100 .

[0119] The first pipeline 410 includes a third first pipeline section 413 . The third first pipeline section 413 extends into the foam layer 300 between the refrigerating chamber 100 and the freezing chamber 200 to be connected to the second pipeline 420 .

[0120] The three-section structure of the first pipeline 410 fully utilizes the back space of the refrigerating chamber 100 and the space of the foaming layer 300 between the refrigerating chamber 100 and the freezing chamber 200, while also facilitating connection with the water storage box and the ice maker.

[0121] In some embodiments, reference Figure 2 and Figure 4 The rear wall of the refrigerator compartment 100 is provided with a plurality of first stoppers 110, spaced apart along the extending direction of the first pre-buried pipe section 431. The first stoppers 110 serve to limit the first pre-buried pipe section 431, preventing it from shifting during refrigerator operation. For example, the first stoppers 110 may be configured as pipe clamps.

[0122] In some embodiments, a second stopper 240 is provided on the top wall of the freezer compartment 200. The second stopper 240 limits the second section 432 of the pre-buried pipe to prevent the second section 432 from moving when the refrigerator is heated. For example, the second stopper 240 is a pipe clamp structure.

[0126] In other words, the covering portion 500 blocks the first opening 210 , and the first end of the second pipe 420 extends through the first opening 210 and the second opening 530 to be connected to the ice maker.

[0127] When the second pipeline 420 needs to be replaced, the cover 500 is removed, and the second pipeline 420 is pulled from the inside of the freezing chamber 200 to separate the second pipeline 420 from the connector 450 and take the second pipeline 420 out of the embedded pipeline 430.

[0128] When installing the second pipe 420, the second pipe 420 is extended from the interior of the freezing chamber 200 through the first opening 210 into the embedded pipe 430, and one end of the second pipe 420 is inserted into the connector 450 to complete the installation. After the second pipe 420 is installed, the cover 500 is installed.

[0129] The first opening 210 is an elongated opening, and the end opening of the pre-buried pipeline 430 is also an elongated opening. The second opening 530 is located at one end of the elongated opening. When removing or installing the second pipeline 420, the second pipeline 420 enters and exits the pre-buried pipeline 430 along the elongated opening, which facilitates the removal and installation of the second pipeline 420.

[0130] In some embodiments, reference Figure 14 A protrusion 230 is provided on the inner top wall of the freezing chamber 200 , and the protrusion 230 surrounds the first opening 210 .

[0131] Reference Figure 15 The cover portion 500 includes a cover body portion 510, which is a flat plate-shaped structure and is provided with a first opening 210. The cover portion 500 includes a cover flange portion 520, which extends from the peripheral edge of the cover body portion 510 toward the top wall of the freezer compartment 200. The cover flange portion 520 is buckled onto the raised portion 230, and the cover body portion 510 covers the first opening 210.

[0132] In other embodiments, referring to Figure 10 The pipeline 460 is a whole metal pipe, a first end of the metal pipe is connected to the water storage box, and a second end of the metal pipe is connected to the ice maker.

[0133] Pipeline 460 is set as a whole pipe, compared to Figure 8 The two-section pipeline shown has a simple structure of the entire pipeline.

[0134] In this embodiment, the pre-buried pipeline 430 is configured as follows Figure 9 The two-half pre-buried pipeline shown facilitates the installation of the entire pipeline 460.

[0135] In other embodiments, the heating element 440 is configured to heat a portion of the metal pipe close to the freezing chamber 200 or close to the refrigerating chamber 100 .

[0136] For example, refer to Figure 10 The first heating element 441 heats the portion of the metal pipe close to the freezing chamber 200. Since the metal pipe has good thermal conductivity, the heat can be quickly transferred to the entire pipe 460, thus preventing the pipe 460 from freezing.

[0137] For example, refer to Figure 10 The second heating element 442 heats the portion of the metal pipe close to the refrigerating chamber 100. Since the metal pipe has good thermal conductivity, the heat can be quickly transferred to the entire pipe 460, thus preventing the pipe 460 from freezing.

[0138] For example, refer to Figure 10 A first heating element 441 and a second heating element 442 are simultaneously provided on the metal pipe. By setting the heating time and the opening sequence of the first heating element 441 and the second heating element 442, the pipe 460 is effectively prevented from freezing.

[0139] In other embodiments, the water delivery module 400 includes an outer pipeline, and a receiving cavity is formed inside the outer pipeline.

[0140] The water delivery module 400 includes an inner pipeline which passes through the receiving cavity and is configured to guide the water in the water storage box to the ice maker.

[0141] The water delivery module 400 includes a heating element 440. The heating element 440 is disposed in the outer pipeline and is configured to heat the inner pipeline to prevent the pipeline from freezing.

[0142] The external piping provides installation space for the internal piping and heating element 440, resulting in a compact overall structure for the water delivery module 400. The external piping is strategically positioned based on the refrigerator's structural layout to fully utilize the refrigerator's structural space. This allows the water storage box in the ice-making module to deliver water to the ice maker while preventing pipe blockage due to ice formation.

[0143] In other embodiments, the external pipeline is arranged in the foam layer 300 of the refrigerator, which has a good heat preservation effect and further prevents the pipeline from freezing.

[0144] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0145] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
