As shown in fig. 14, 16 and 21, the water injection assembly 300 includes a positioning seat 330, and a main body of the positioning seat 330 is penetrated in a positioning channel 701 of the base 700. The positioning seat 330 is provided with a water inlet channel 335, and the water inlet channel 335 is smooth, such as a structure without a protrusion or a groove, so that water is not easy to remain in the water inlet channel 335. The water inlet channel 335 has a water inlet 3351 and a water outlet 3352, and water enters the water inlet channel 335 through the water inlet 3351 and flows into the ice maker 200 through the water outlet 3352.

As shown in fig. 16 and 21, the end (e.g., rear end) of the positioning seat 330, which is far away from the door body 800, forms a water inlet 3351, and the end (e.g., front end) of the water injection assembly 300, which is near the door body 800, forms a water outlet 3352. The positioning seat 330 is configured to be inclined downward in a direction from one end away from the door body 800 to one end close to the door body 800 (e.g., in a direction from the rear end to the front end).

For example, referring to fig. 14, 15 and 16, in the height direction of the case 100, the water inlet 3351 of the water inlet channel 335 is disposed higher than the water outlet 3352 of the water inlet channel 335 with an acute angle γ (as shown in fig. 14) between the central axis of the water inlet channel 335 and the rear sidewall of the housing 110.

In this way, water flowing into the water inlet channel 335 from the water inlet 3351 can be discharged through the water outlet 3352 by gravity and further flows into the ice maker 200, and is not easily remained in the water inlet channel 335. In addition, the water inlet efficiency of the water injection assembly 300 can be prevented from being affected by freezing due to water residue near the water outlet 3352 of the water inlet channel 335.

In some embodiments, as shown in fig. 15, the main body of the positioning seat 330 is penetrated in the positioning channel 701 of the base 700, and the water outlet 3352 of the water inlet channel 335 is positioned at the upper portion inside the freezing chamber 121, thereby reserving enough space for the installation of the ice maker 200 to facilitate the installation of the ice maker 200.

In some embodiments, the water outlet 3352 of the water inlet channel 335 is in direct communication with the ice maker 200. Alternatively, in some embodiments, ice maker 200 has water fill port 210, and water outlet 3352 of water inlet channel 335 communicates with ice maker 200 through water fill port 210.

As shown in fig. 15, since the water injection assembly 300 is disposed close to the air duct 101, the water injection assembly 300 may be affected by the low temperature air in the air duct 101 to reduce the temperature, which may cause icing or frosting in the water inlet channel 335.

In some embodiments, as shown in fig. 20 and 21, the refrigerator 1 further includes a heating device 600, the heating device 600 being disposed at an outer circumferential side of the positioning seat 330 and configured to heat the positioning seat 330. Therefore, when the water inlet channel 335 is frozen or frosted, the ice or frost in the water inlet channel 335 can be melted by the heating device 600, so that the influence of the air duct 101 on the water inlet channel 335 can be reduced, and the water in the water inlet channel 335 can be ensured to flow into the ice maker 200.

In some embodiments, as shown in fig. 15 and 16, the refrigerator 1 further includes a heat insulating layer 601, and the heat insulating layer 601 is disposed between the heating device 600 and the inner wall of the fourth installation cavity 144 and configured to insulate heat transfer between the heating device 600 and the air duct 101, so that heat generated by the heating device 600 is used for melting ice or frost in the water inlet channel 335, which is high in energy utilization efficiency and is beneficial to reducing power consumption of the refrigerator 1.

For example, the insulation layer 601 may be a rectangular sponge sheet including two sides, one of which is provided with a glue layer through which the rectangular sponge sheet can be firmly attached to the outside of the heating device 600.

In some embodiments, as shown in fig. 21, the positioning seat 330 includes a plug portion 333 and an abutment portion 332. The insertion portion 333 is inserted into the positioning channel 701, and the water inlet channel 335 is defined inside the insertion portion 333. The heating device 600 is provided on the outer peripheral side of the insertion portion 333. The abutting portion 332 is disposed at an end of the insertion portion 333 away from the door 800. When the positioning seat 330 is inserted into the positioning channel 701 of the base 700, the abutment portion 332 can abut the positioning seat 330 against an end (e.g. a rear end) of the base 700 away from the door 800, so as to limit the positioning seat 330.

In some embodiments, as shown in fig. 21, the abutment 332 is formed in a substantially rectangular plate structure with a via hole provided thereon.

In some embodiments, as shown in fig. 21, the positioning seat 330 further includes a water inlet nozzle 331, where the water inlet nozzle 331 is disposed on a side of the abutting portion 332 away from the door 800, and corresponds to a position of the via hole on the abutting portion 332. The water inlet 331 is tubular and has a water inlet 3311. The water inlet port 3311 communicates with the water inlet channel 335 through the through hole on the abutting portion 332.

In some embodiments, as shown in FIG. 21, both the water inlet channel 335 and the water inlet nozzle 331 are tubular. The diameter of the cross section of the water inlet channel 335 is larger than the diameter of the water inlet opening 3311. Therefore, when water flows into the water inlet channel 335 from the water inlet port 3311, water and air coexist in the water inlet channel 335, and thus, negative pressure is not easily formed in the water inlet channel 335, so that water in the water inlet channel 335 can smoothly flow into the ice maker 200, and thus, ice formation in the water inlet channel 335 can be prevented.

In some embodiments, as shown in fig. 20, the water injection assembly 300 further includes a sponge block 305, the sponge block 305 being disposed between the abutment 332 and the rear end of the base 700.

As shown in fig. 16, the sponge block 305 has a first surface and a second surface, the first surface and the second surface being disposed opposite to each other in the thickness direction of the sponge block 305, the first surface being closer to the door than the second surface. The first surface of the sponge block 305 abuts against one side of the abutting portion 332 near the door 800, and the second surface of the sponge block 305 abuts against both the rear end of the base 700 and one end (e.g., the rear end) of the heating device 600 far from the door 800.

Because the sponge block 305 has a heat insulation effect, the heat generated by the heating device 600 can be completely used for melting ice or frost in the water inlet channel 335, so that the energy utilization rate is high and the power consumption of the refrigerator 1 is reduced.

In addition, the sponge block 305 may also play a role of sealing to prevent the cold air in the freezing chamber 121 from leaking outside, so that dew at the rear sidewall of the case 100 may be prevented.

In some embodiments, as shown in fig. 18, 19 and 20, the water injection assembly 300 further includes a water injection tube 320 and an adapter 303. The adapter 303 defines an adapter cavity 304 therein, and the adapter cavity 304 extends through both ends of the adapter 303. The adapter 303 is configured to connect the water injection pipe 320 with the water inlet 331.

For example, referring to fig. 20, the inner diameter of the adapter 303 is slightly smaller than the outer diameter of the water injection pipe 320 and the outer diameter of the water inlet nozzle 331, so that an interference fit can be achieved between the adapter 303 and the water injection pipe 320, and between the adapter 303 and the water inlet nozzle 331. In this way, a reliable connection between the water injection pipe 320 and the adapter 303, and between the water inlet nozzle 331 and the adapter 303 can be achieved.

The water flows from the water injection pipe 320 into the ice maker via the switching cavity 304, the water inlet nozzle 331 and the water inlet channel 335 in sequence.

In some embodiments, as shown in fig. 20, the adaptor 303 is a flexible tube, so that the connection direction of the water injection pipe 320 can be changed by the adaptor 303, thereby facilitating the arrangement of the water injection pipe 320.

In some embodiments, as shown in fig. 22, the heating device 600 includes a connection terminal 610, a heating wire 620, an aluminum foil 630, and a wire harness 640. The heating wire 620 is provided at the outer circumferential side of the insertion portion 333. The heating device 600 includes two layers of aluminum foils 630, one layer of aluminum foil 630 is disposed between the heating wire 620 and the plug portion 333, and the other layer of aluminum foil 630 is disposed on a side (e.g., an outer side) of the heating wire 620 away from the plug portion 333. One end of the wire harness 640 is extended between the two aluminum foils 630 and connected to the heating wire 620, and the other end of the wire harness 640 is located outside the two aluminum foils 630 and connected to the connection terminal 610, so that the heating wire 620 can be powered through the connection terminal 610 and the wire harness 640.

In some embodiments, as shown in fig. 22, the aluminum foil 630 is rectangular in shape and the heater wire 620 is disposed in a circuitous manner between the two layers of aluminum foil. The two layers of aluminum foils are adhered and connected. The aluminum foil 630 is adhered to the outer circumferential side of the insertion portion 333, thereby achieving connection of the heating device 600 with the positioning seat 330.

In some embodiments, the heater wire 620 operates intermittently (e.g., power is intermittently supplied to the heater wire 620 by connecting the terminal 610 to a power supply). For example, the heating wire 620 may be operated in synchronization with the compressor of the refrigerator 1. When the compressor is operated, the temperature of the freezing chamber 121 is lowered, and the heating wire 620 is powered by the power supply, so that the heating wire 620 starts to be heated. When the compressor stops operating, the temperature of the freezing chamber 121 increases, and the power supply stops supplying power to the heating wire 620, so that the heating wire 620 stops heating. In this way, the water in the water inlet channel 335 can be prevented from frosting or icing due to too low temperature, and the power supply to the heating wire 620 is interrupted, so that the water in the water inlet channel 335 is prevented from being too high due to the overheating of the heating wire 620, and the power consumption of the refrigerator 1 can be reduced.

In some embodiments, as shown in fig. 21, the positioning socket 330 further includes a receiving slot 334. The outer circumferential surface of the insertion portion 333 is recessed inward to form an accommodation groove 334. The extending direction of the accommodating groove 334 coincides with the extending direction of the insertion portion 333. One end (e.g., a rear end) of the receiving groove 334 away from the door body 800 extends to the abutting portion 332, and one end (e.g., a front end) of the receiving groove 334 near the door body 800 extends to the water outlet 3352 of the water inlet channel 335. The one end of the wire harness 640 is positioned in the receiving groove 334 and connected to the heating wire 620, and the other end of the wire harness 640 is protruded from the front end of the receiving groove 334 and connected to the connection terminal 610. Thus, the volume of the heating device 600 assembled with the water injection assembly 300 can be reduced, and the space utilization of the refrigerator 1 can be improved.

In addition, the receiving groove 334 may also protect the harness 640 from damage.

In some embodiments, as shown in fig. 23 and 24, the base 700 includes a guide portion 720, a first sealing plate 710, and a second sealing plate 730, the first sealing plate 710 being closer to the door body 800 than the second sealing plate 730.

The guide portion 720 is inserted into the fourth mounting cavity 144, and the positioning channel 701 is disposed along the extending direction of the guide portion 720 and penetrates through two ends of the guide portion 720 along the extending direction.

The first sealing plate 710 is disposed at one end (e.g., a front end) of the guide portion 720 near the door body 800. The first sealing plate 710 is located in the fourth mounting chamber 144 and abuts against the freezing chamber 121. So that the contact area between the base 700 and the freezing chamber 121 can be increased, and the sealing effect of the freezing chamber 121 can be improved.

The second sealing plate 730 is disposed at an end (e.g., rear end) of the guide portion 720 remote from the door body 800. The second sealing plate 730 is located in the fourth mounting cavity 144 and abuts the housing 110. A side surface of the second sealing plate 730, which is far from the door body 800, is parallel to the rear sidewall of the housing 110, so that a larger contact area is provided between the second sealing plate 730 and the housing 110, thereby being beneficial to improving the sealability of the housing 110.

In some examples, the base 700 further includes a sealing gasket disposed between the rear side of the second sealing plate 730 and the housing 110, by which the sealing effect between the second sealing plate 730 and the housing 110 may be improved.

If the first sealing plate 710 is directly abutted against the freezing chamber 121, leakage of cold air is likely to occur, and thus, there is a high demand for sealability between the first sealing plate 710 and the freezing chamber 121.

In some embodiments, as shown in fig. 16, the freezing chamber 121 further includes a mounting stage 123, the mounting stage 123 being disposed on an outer side of the freezing chamber 121 away from a side wall of the door 800.

The mounting table 123 includes a first wall surface 1231, a second wall surface 1232, and a third wall surface 1233. The first wall surface 1231 extends in the height direction of the refrigerator 1. The second wall surface 1232 is located at the bottom end of the first wall surface 1231 and extends in a direction away from the door body 800. The third wall surface 1233 is located at the top end of the first wall surface 1231 and extends in a direction toward the door body 800.

The first seal plate 710 is adapted to the contour of the mounting table 123. As shown in fig. 23 and 24, the first sealing plate 710 includes a first sealing portion 711, a second sealing portion 712, and a third sealing portion 713. The shape of the first sealing part 711 is adapted to the shape of the first wall surface 1231. The shape of the second sealing part 712 is adapted to the shape of the second wall surface 1232. The third sealing portion 713 is adapted to the shape of the third wall surface 1233.

In this way, by bringing the first sealing portion 711 into contact with the first wall surface 1231, bringing the second sealing portion 712 into contact with the second wall surface 1232, and bringing the third sealing portion 713 into contact with the third wall surface 1233, the contact area between the first sealing plate 710 and the freezing chamber 121 can be increased, which is advantageous in improving the sealing performance of the freezing chamber 121.

In some embodiments, as shown in fig. 23 and 24, the first seal plate 710 further includes a first spacing bead 714. The first limiting rib 714 is disposed on a surface (e.g., a front side) of the first sealing plate 710 near the door body 800, and extends toward a direction near the door body 800.

As shown in fig. 16, the mounting table 123 is provided with a first limiting groove adapted to the first limiting rib 714. The first limiting rib 714 is matched with the first limiting groove, so that when the first sealing plate 710 is installed on the mounting table 123 in a butt joint mode, the base 700 can be limited, displacement of the base 700 before foaming of the foaming layer 140 can be avoided, and the reliability of assembly is improved.

In some embodiments, as shown in fig. 23 and 24, the second sealing plate 730 further includes a second stop rib 731. The second limiting rib 731 is disposed on a side surface (e.g., a rear side surface) of the second sealing plate 730 away from the door body 800, and extends toward a direction away from the door body 800. The second stop rib 731 is substantially rectangular in front projection on the rear side of the second seal plate 730.

As shown in fig. 16, the housing 110 includes a second limiting groove that mates with the second limiting rib 731. The second limiting groove is a rectangular groove slightly larger than the second limiting rib 731. The second limiting rib 731 is matched with the second limiting groove, so that when the second sealing plate 730 is installed on the housing 110 in a abutting manner, the base 700 can be limited, and therefore the base 700 can be prevented from being displaced before the foaming layer 140 is foamed, and the reliability of assembly is improved.

In some embodiments, as shown in fig. 16 and 20, the wire harness 640 may also be bent upward from a front end near the receiving groove 334 and connected to the connection terminal 610.

In this case, as shown in fig. 22 and 23, the base 700 further includes a first settling stage 740. A first countersink 740 is disposed on the first seal plate 710, the first countersink 740 being configured to receive the upwardly bent wire harness 640. For example, the first sinking stage 740 is formed by recessing a portion of the first sealing plate 710 close to the guide portion 720 in the extending direction of the guide portion 720 and toward a direction away from the door body 800.

As shown in fig. 16 and 23, the first settling platform 740 includes a terminal hole 741. The terminal hole 741 penetrates the first land 740. The terminal hole 741 is penetrated through the terminal 610, so that the power supply can be connected through the terminal 610, which is beneficial to shortening the length of the wire harness 640 and improving the safety of the refrigerator 1.

In some embodiments, as shown in fig. 23 and 24, the base 700 further includes a second counter plate 750, the second counter plate 750 being disposed on the second sealing plate 730. The second sinking stage 750 is formed by recessing a portion of the second sealing plate 730 adjacent to the guide portion 720 in the extending direction of the guide portion 720 and toward the direction adjacent to the door 800. The second counter 750 is configured to cooperate with the abutment 332 to limit the abutment 332, thereby facilitating reliable assembly of the water injection assembly 300 with the base 700.

In some embodiments, as shown in fig. 24, the aperture of the positioning channel 701 decreases in a direction toward the freezing chamber 121. In a longitudinal section passing through the axis of the positioning channel 701, an included angle between the inner wall of the positioning channel 701 and the axis of the positioning channel 701 is less than or equal to 2 °, so that when the plug portion 333 of the water injection assembly 300 is inserted into the base 700 from the rear side of the case 100, the tightness between the plug portion 333 and the inner wall of the positioning channel 701 increases as the aperture of the positioning channel 701 decreases.

For example, referring to fig. 24, in order to secure the sealing reliability between the insertion portion 333 and the positioning passage 701, an angle θ between both side walls of the positioning passage 701 is smaller than 3 ° in a longitudinal section passing through the axis of the positioning passage 701. For example, the included angle θ (see fig. 24) may be 0.5 °, 1 °, 1.5 °, 2 °, 3 °, or the like.

In some embodiments, as shown in fig. 20, the heating device 600 has a maximum radial dimension D1. As shown in fig. 24, an end of the guide portion 720 near the second sealing plate 730 has an inner diameter D2, D2 being approximately equal to D1.

The heat insulation layer 601 is heat insulation cotton and can be deformed under pressure, so that the water injection assembly 300 is easy to insert into the guide part 720 of the base. Also, since the aperture of the positioning passage 701 is reduced in a direction toward the freezing chamber 121, the mating of the insertion portion 333 and the guide portion 720 is relatively tight.

In some embodiments, as shown in fig. 17, the refrigerator 1 further includes an ice bank 104. The ice bank 104 is disposed below the ice outlet of the ice maker 200, and ice cubes made by the ice maker 200 are easily collected by the ice bank 104.

In some embodiments, as shown in fig. 25 and 26, the freezing chamber 121 may also be provided at a lower portion of the case 100. By disposing the freezing chamber 121 at the lower portion of the case 100, the length of the water injection pipe 320 can be shortened, which is advantageous in reducing the difficulty of assembling the water injection assembly 300.

Some embodiments of the present disclosure provide a refrigerator 1, the refrigerator 1 including a cabinet 100, an ice maker 200, a water injection assembly 300, and a heating device 600.

The cabinet 100 includes a freezing chamber 121 at an upper portion of the cabinet 100, and a refrigerating chamber 122 at a lower portion of the cabinet 100. The freezing chamber 121 includes a first mounting hole opened on a top wall of the freezing chamber 121. The refrigerating compartment 122 includes a second mounting hole opened at a sidewall (e.g., a right sidewall) of the refrigerating compartment 122.

In some embodiments, as shown in fig. 14, the ice maker 200 is disposed in the freezing chamber 121 at an inner top of the freezing chamber 121 and near a side of the freezing chamber 121 near the door 800. This facilitates the user to take ice through the dispenser on the door.

As shown in fig. 14, the water injection assembly 300 is disposed in the foaming layer 140. The ice maker 200 includes a water filling port 210, and the water filling assembly 300 is connected to the water filling port 210 through the first mounting hole.

As shown in fig. 27, 29 and 30, the water injection assembly 300 includes a fixing plate assembly 360, a water injection pipe 320, a heat conductive pipe sleeve 306, a bracket member 340 and a pipe fixing member 350.

In some embodiments, as shown in fig. 27 to 29, the water injection pipe 320 extends substantially in the height direction of the refrigerator 1. As shown in fig. 37, the refrigerator 1 further includes a water supply pipe 1221 and a water supply device 1222. The water supply pipe 1221 and the water supply device 1222 are both located in the refrigerating chamber 122. The water supply device 1222 includes a water storage box and a water pump 1221 in communication with the water storage box, the water pump configured to pump water from the water storage box into the water supply pipe 1221.

The water inlet end of the water injection pipe 320 extends into the pipe fixing member 350, and the water supply pipe 1221 of the refrigerating chamber 122 extends into the pipe fixing member 350 through the second mounting hole. In this way, the water inlet end of the water injection pipe 320 is connected to the water supply pipe 1221 in the refrigerating chamber 122 by the pipe fixing member 350. The water outlet end of the water injection pipe 320 is positioned above the outer top wall of the freezing chamber 121, and is connected with the water injection port 210 of the ice maker 200 by penetrating the first mounting hole.

In this way, the ice making water may be delivered to the water inlet end of the water injection pipe 320, flow to the water outlet end of the water injection pipe 320 through the water injection pipe 320, and then enter the ice maker 200 through the water injection port 210, thereby supplying water to the ice maker 200.

In some embodiments, as shown in fig. 27, 29 and 30, the heat conductive sleeve 306 is sleeved over a portion of the pipe section of the water injection pipe 320 above the freezer compartment 121. As shown in fig. 32, L1 is one end of the heat conduction pipe sleeve 306, and L2 is the other end of the heat conduction pipe sleeve 306.

In some embodiments, as shown in fig. 22, the heating device 600 may include a heating wire 620 and a wire harness 640. The heating wire 620 is disposed at an outer circumferential side of the heat conductive pipe sleeve 306, and is configured to heat the heat conductive pipe sleeve 306. The harness 640, coupled to the heating wire 620, is configured to power the heating wire 620. The heat conducting pipe sleeve 306 can transfer the heat generated by the heating device 600 to the water injection pipe 320, so that the water in the water injection pipe 320 can be heated, which is beneficial to preventing the water in the pipe section of the water injection pipe 320 from freezing.

In some embodiments, as shown in fig. 30 and 31, the fixed plate assembly 360 includes a fixed plate 361, a first stopper 362, and a second stopper 363. For example, the first limiting member 362 is a limiting tube, and the second limiting member 363 is a limiting bracket.

The fixed plate 361 is disposed at an outer top wall of the freezing chamber 121, and the first and second stoppers 362 and 363 are each disposed on a top surface of the fixed plate 361.

The first stopper 362 has a lumen 3626 provided therein, and the lumen 3626 communicates with the freezing chamber 121. The first stopper 362 is configured to accommodate the heat conductive pipe sleeve 306 to isolate the foaming glue from penetrating into the freezing chamber 121 when the refrigerator 1 is foamed.

The second limiting member 363 is configured to limit a pipe section of the water injection pipe 320, which is located at the top of the freezing chamber 121 and is not sleeved with the heat conduction pipe sleeve 306, above the freezing chamber 121, and space the pipe section from the freezing chamber 121 by a first predetermined distance D3, where the first predetermined distance D3 may be adaptively set according to actual needs.

In some embodiments, referring to fig. 30 and 31, the first stop 362 includes a boss 3621, a cover 3622, a first catch 3623, and a second catch 3624.

The boss 3621 is formed on the fixed plate 361. That is, the boss 3621 is integral with the fixed plate 361. A lumen 3626 is defined between the boss 3621 and the fixed plate 361. One end of the pipe 3626 in the extending direction corresponds to the position of the first mounting hole so that the pipe 3626 communicates with the freezing chamber 121.

The protruding portion 3621 has two side edges, which are respectively located at the connection portions of the protruding portion 3621 and the fixing plate 361, and the first catch 3623 is provided at one side edge of the protruding portion 3621. For example, the first stop 362 includes a first catch 3623. Alternatively, the first limiting member 362 includes two first buckles 3623, and the two first buckles 3623 are respectively disposed at two side edges of the protruding portion 3621.

The cover 3622 is fitted over the boss 3621, and covers an end edge of the other end of the lumen 3626 of the boss 3621 in the extending direction.

The second catch 3624 is disposed on the cover 3622 and mates with the first catch 3623. The second buckles 3624 are the same as the first buckles 3623 in number and are arranged in one-to-one correspondence. In this way, the fitting connection of the boss 3621 and the cover 3622 can be achieved by the engagement of the first catch 3623 and the second catch 3624.

The middle portion of the cover 3622 is provided with a middle hole 3625 provided through the cover 3622 in the thickness direction. The aperture of the central bore 3625 is larger than the outer diameter of the thermally conductive sleeve 306 to enable the thermally conductive sleeve 306 to pass through the central bore 3625 and lumen 3626.

In addition, since the aperture of the middle hole 3625 is slightly larger than the outer pipe diameter of the heat conducting pipe sleeve 306, the gap between the middle hole 3625 and the heat conducting pipe sleeve 306 is smaller, so that the foaming glue can be prevented from entering the freezing chamber 121 through the first mounting hole when the refrigerator 1 is foamed.

In some embodiments, referring to fig. 30 and 31, the second stop 363 includes at least two legs 3631, a first lumen 3632, and a second lumen 3633.

The bottom of each leg 3631 is fixed to the fixed plate 361, and the top of each leg 3631 is connected to the first lumen 3632. At least two legs 3631 are integrally formed with the first lumen 3632. The first cavity 3632 has an upward opening and the second cavity 3633 has a downward opening so that the second cavity 3633 cooperates with the first cavity 3632 to form a full cavity configured to retain a tube segment of the water injection tube 320 that is not sleeved with the heat conducting tube sleeve 306 above the freezing chamber 121 such that the tube segment is spaced a first predetermined distance from the freezing chamber 121.

In this way, the water in the water injection pipe 320 may be spaced apart from the freezing chamber 121 by the first predetermined distance D3 when passing through the top of the freezing chamber 121, which is advantageous for increasing the thickness of the foaming layer 140 between the water injection pipe 320 and the freezing chamber 121. In addition, the water in the water injection pipe 320 is prevented from condensing into ice due to being too close to the freezing chamber 121 by the heat insulation effect of the foaming layer 140.

In some embodiments, as shown in fig. 32, the heat conductive sleeve 306 is an aluminum tube, and thus, the heat conductive sleeve 306 has good plastic properties and heat conductive properties.

For example, the inner tube diameter of the thermally conductive sleeve 306 may be slightly larger than the outer tube diameter of the water injection tube 320. For example, the inner diameter of the thermally conductive sleeve 306 is 0.1mm to 1.2mm larger than the outer diameter of the water injection pipe 320. For example, the inner diameter of the thermally conductive sleeve 306 is 0.1mm, 0.2mm, 0.3mm, 0.5mm, 0.75mm, or 1.0mm greater than the outer diameter of the water injection tube 320.

Because the gap between the heat conduction pipe sleeve 306 and the water injection pipe 320 is small (only 0.1mm to 1.2 mm), the water injection pipe 320 is not easy to be separated from the heat conduction pipe sleeve 306 when the heat conduction pipe sleeve 306 is bent, and thus the assembly reliability of the heat conduction pipe sleeve 306 and the water injection pipe 320 is improved.

In some embodiments, as shown in fig. 32, the thermally conductive sleeve 306 includes a plurality of bent segments, e.g., the thermally conductive sleeve 306 may be configured in a zig-zag fashion, etc. Thus, the space can be reasonably utilized, and the space utilization rate of the refrigerator 1 can be improved.

In some embodiments, the water outlet end of the water injection pipe 320 and the pipe wall thickness at the turn are greater than the pipe wall thickness of the other pipe sections of the water injection pipe 320. Thus, not only the reliability of the water injection pipe 320 can be ensured, but also the cost can be reduced.

In some embodiments, since the aluminum tube has good heat conduction performance, the heating device 600 may be directly attached to the heat conduction pipe sleeve 306, so that the heating efficiency of the heat conduction pipe sleeve 306 may be improved.

For example, the heating device 600 may be attached to a portion of the outer wall of the heat conductive pipe sleeve 306 to heat the heat conductive pipe sleeve 306, and the portion of the outer wall of the heat conductive pipe sleeve 306 may transfer heat generated by the heating device 600 to various positions of the heat conductive pipe sleeve 306, so that the assembly between the heating device 600 and the heat conductive pipe sleeve 306 may be simplified. In addition, the thermally conductive sleeve 306 may also transfer heat to the water injection tube 320, thereby facilitating the prevention of water within the water injection tube 320 from freezing.

In some embodiments, as shown in fig. 27 and 33 to 35, the bracket member 340 is provided on a rear sidewall of the freezing chamber 121 (e.g., a sidewall of the freezing chamber 121 remote from the door 800). The holder member 340 is configured to restrain the water injection pipe 320 at the rear of the rear sidewall of the freezing chamber 121 and to space the water injection pipe 320 from the freezing chamber 121 by a second predetermined distance D4.

In some examples, the bracket member 340 is a foam member as shown in fig. 33, the bracket member 340 including a bracket member body 345 and a tube channel 344. The pipe passage 344 is provided at a side of the holder member body 345 remote from the freezing chamber 121. The bracket member body 345 has a first face 341, a second face 342, and a third face 343.

For example, as shown in fig. 33, the first face 341 is parallel to the rear sidewall of the freezing chamber 121, and the second face 342 is parallel to the sidewall of the freezing chamber 121 (e.g., the left sidewall or the right sidewall of the freezing chamber 121). The second face 342 is perpendicular to the first face 341, and a step is formed between the second face 342 and the first face 341.

As shown in fig. 33, the first surface 341 and the second surface 342 are both provided with a glue layer, the first surface 341 is adhered to the rear sidewall of the freezing chamber 121 by the glue layer, and the second surface 342 is adhered to one of two sidewalls of the freezing chamber 121 perpendicular to the door 800 (for example, on the right sidewall 1212 of the freezing chamber 121 as shown in fig. 33) by the glue layer, so that the connection of the bracket member body 345 and the freezing chamber 121 can be achieved. The glue layer may be, for example, a 3M double sided glue.

For example, the third surface 343 is a side surface of the bracket member body 345 away from the first surface 341, and the third surface 343 is parallel to the first surface 341. The pipe passage 344 is provided on the third face 343 and extends in the height direction of the refrigerator 1 (up-down direction as shown in fig. 33), and the pipe passage 344 penetrates the bracket member body 345 in the height direction of the refrigerator 1. The tube channel 344 is configured to retain the water injection tube 320 on the bracket member body 345. The pipe passage 344 is spaced apart from the freezing chamber 121 by a second predetermined distance D4 of about 70mm. In this way, the water in the water injection pipe 320 can be prevented from freezing due to being too close to the freezing chamber 121.

In some embodiments, as shown in fig. 27, 28, 36 and 37, the tube holder 350 includes a body member 355, a tab 351, a first fastener 352 and a second fastener 353.

The projection of the main body member 355 on the right side wall of the refrigerating chamber is substantially rectangular, the length direction of the main body member 355 is parallel to the height direction of the refrigerator 1, and the insertion piece 351 is provided at the bottom of the main body member 355 in the length direction. The side wall (e.g., right side wall) of the refrigerating chamber 122 is provided with a plugging slot matched with the plugging piece 351, and the preliminary fixing of the pipe fixing frame 350 on the refrigerating chamber 122 can be realized through the matching of the plugging piece 351 and the plugging slot.

The pipe fixing member 350 includes two first fastening members 352, and the two first fastening members 352 are symmetrically disposed at both sides of the body member 355 in the width direction. The second fastening member 353 is disposed at the top of the body member 355 in the longitudinal direction.

Correspondingly, two first buckling parts and one second buckling part are also arranged on the side wall of the refrigerating chamber 122. The two first fastening parts are matched with and correspond to the two first fasteners 352 one by one. The one second fastening portion is matched with the second fastening member 353.

Thus, the mounting of the fixing frame 350 on the refrigerating compartment 122 can be achieved by the engagement of the first fastening member 352 with the first fastening portion and the engagement of the second fastening member 353 with the second fastening portion.

The pipe fixing member 350 has a first opening 3551 and a second opening 3552, the first opening 3551 being provided at a top wall of the body member 355, and the second opening 3552 being provided at a lower portion of the body member 355 near a side wall of the door body 800. The second opening 3552 corresponds to the position of the second mounting hole described above so that the tub cavity 354 communicates with the refrigerating compartment 122.

The body member 355 defines a receiving cavity 354, the receiving cavity 354 extending along the length of the body member 355. The vessel lumen 354 is configured to receive the water inlet end of the water injection tube 320. The water inlet end of the water injection pipe 320 extends into the cavity 354 through the first opening 3551, and the water supply pipe 1221 sequentially extends into the cavity 354 through the second mounting hole and the second opening 3552, and is connected to the water injection pipe 320.

In some embodiments, each component of the water injection assembly 300 is fixed in the foaming layer 140 after foaming of the foaming gel in the foaming layer 140 is completed during assembly of the refrigerator 1, so that reliability and stability of each component of the water injection assembly 300 can be improved.

Some embodiments of the present disclosure provide a refrigerator 1, as shown in fig. 4 and 38, the refrigerator 1 includes a cabinet 100, an ice maker 200, a water injection pipe 320, a mounting box 400, and a water valve assembly 500.

In some embodiments, as shown in fig. 38, the cabinet 100 includes a compressor compartment 130, the compressor compartment 130 being disposed below the cabinet 100. The compressor compartment 130 is separated from other compartments (e.g., the freezer compartment 121 or the refrigerator compartment 122) in the cabinet 100 by a foaming layer 140.

In some embodiments, as shown in fig. 39-41, a mounting box 400 is disposed in the compressor compartment 130. The mounting box 400 defines a first accommodating cavity 401 and a second accommodating cavity 402, and the mounting box 400 includes a box body 410 and a box cover 420, where the box body 410 is adapted to the box cover 420.

In some embodiments, as shown in fig. 41 and 42, a water valve 501 is disposed in the second receiving chamber 402, the outer contour of the water valve 501 being adapted to the second receiving chamber 402. Therefore, by installing the water valve 501 in the second accommodating cavity 402 and closing the box body 410 and the box cover 420, the water valve 501 can be limited in the second accommodating cavity 402, and at this time, six degrees of freedom of the water valve 501 are limited, so that the water valve 501 can be prevented from loosening, which is beneficial to improving the working stability of the water valve 501.

In some embodiments, as shown in fig. 42, the wiring assembly 530 includes a water valve wiring terminal 533, a first wire 531, and a second wire 532.

In addition, as shown in fig. 42, the water outlet connector 520 passes through a side wall of the case 410 to extend from the inside of the mounting case 400 to the outside of the mounting case 400. The water outlet connector 520 is connected to one end of the water injection pipe 320. The other end of the water injection pipe 320 is connected to the water injection port 210 of the ice maker 200. In this way, water can be delivered into the ice maker 200 through the water valve 501, and ice making is achieved.

For example, water may first enter the water valve 501 via the water valve inlet pipe 540 and the water inlet connector 510, then be delivered by the water valve 501 to the water outlet connector 520, and enter the water injection pipe 320, and finally flow through the water injection port 210 into the ice maker 200.

In some embodiments, referring to fig. 39, the water inlet fitting 510 extends out from the top wall of the cartridge 410 and the water outlet fitting 520 extends out from the bottom wall of the cartridge 410.

According to the refrigerator of some embodiments of the present disclosure, by disposing both the water valve 501 and the wiring assembly 530 in the installation box 400 and disposing the water receiving end of the water valve 501 (e.g., the portion of the water inlet joint 510 extending out of the box body 410 or the portion of the water outlet joint 520 extending out of the box body 410) outside the installation box 400 such that the water receiving end of the water valve 501 is located outside the installation box 400 and the water valve wiring terminal 533 is located inside the installation box 400, dry-wet separation can be achieved, and even if water leakage occurs at the water receiving end of the water valve 501, water does not contact the water valve wiring terminal 533, thereby preventing the water valve wiring terminal 533 from being shorted.

In addition, by providing the water valve terminal 533 in the mounting box 400, it is possible to prevent an electric shock caused by a user's erroneous touch on the water valve terminal 533.

The first connection part 412 is located at the other side of the box body 414 in the length direction, and the second connection part 422 is located at the other side of the box cover body 425 in the length direction.

In some embodiments, as shown in fig. 39 and 40, the cap 420 further includes a fixing plate 423, and the fixing plate 423 is disposed at one side of the cap body 425 in the width direction and extends in a direction away from the case. The fixing plate 423 is substantially rectangular, and the fixing plate 423 has a bar-shaped hole 424. The bar-shaped hole 424 is configured for a screw to pass through. Thus, the screw is inserted through the bar-shaped hole 424 to fix the mounting box 400 to the case 100.

In addition, screws may pass through any location of the bar-shaped holes 424, thereby allowing the position of the mounting box 400 relative to the case 100 to be adjustable.

In some embodiments, as shown in fig. 41 and 42, the mounting box includes a routing channel 403, the routing channel 403 being defined by the box 410 in cooperation with the cover 420. The trace channel 403 has a first trace port 4031 and a second trace port 4032. The first wiring port 4031 is disposed in the mounting box 400 and is communicated with the first accommodating cavity 401. The second trace port 4032 is disposed on a sidewall (e.g., a sidewall in a length direction) of the box body 414. The second wire 532 is embedded in the wiring channel 403 and passes through the second wiring port 4032 and out of the mounting box 400 to be connected to an external power supply.

In some embodiments, the routing channel 403 includes a first channel 4033, a second communication 4034, and a communication channel 4035 that communicates with the first channel 4033 and the second channel 4034, respectively. One end of the first channel 4033 is formed with a first wiring port 4031, one end of the first channel 4033 is communicated with one end of the second channel 4034 through a communication channel 4035, and the other end of the second channel 4034 is formed with a second wiring port 4032.

For example, the communication channel 4035 may be bent, and thus, the routing channel 403 may be provided as a U-shaped channel or an S-shaped channel. The shape of the routing channel 403 may be adaptively set according to the length of the second wire 532.

It will be appreciated that by providing the routing channel 403 in the mounting box 400, the routing of the second wires 532 may be optimized such that the routing of the second wires 532 is more orderly and the second wires 532 may be prevented from being entangled.

In some embodiments, referring to fig. 39, the second wire hole 4032 is provided at the bottom wall of the box 410, and the second wire 532 passes out from the bottom wall of the box 410.

In some embodiments, as shown in fig. 41 and 42, the cartridge 410 further includes a wire clip 413. The wire holder 413 is disposed in the first accommodating chamber 401. The wire clip 413 is configured to limit the second wire 532.

For example, the case 410 includes a wire clip 413; alternatively, the case 410 includes a plurality of wire clamps 413. Each wire clamping member 413 includes two hooks 4131, and the two hooks 4131 are spaced apart to define a wire clamping space 4132. The second wires 532 are embedded in the wire clamping space 4132, so that the limitation of the second wires 532 is realized.

It will be appreciated that the second wire 532 may be restrained by providing the wire clamping member 413 in the first accommodating chamber 401. In this way, when the user pulls the second wire 532 outside the case, the water valve connection terminal 533 can be prevented from moving synchronously with the second wire 532, so that the first wire 531 can be prevented from being poorly connected with the water valve 501 due to the movement of the water valve connection terminal 533.

The foregoing is merely a specific embodiment of the disclosure, but the protection scope of the disclosure is not limited thereto, and any person skilled in the art who is skilled in the art will recognize that changes or substitutions are within the technical scope of the disclosure.
