[0032] In related technologies, refrigerators use an internal ice-making system to make ice, which provides water through a water tank assembly located within the inner liner. In these systems, the water tank body and the supporting components typically employ a sliding fit to facilitate water filling. However, this sliding fit increases the precision required for the sliding parts, leading to higher requirements for the corresponding molds and increased manufacturing costs. Furthermore, during long-term use, the surfaces of the sliding fit are prone to wear due to friction between the sliding parts. This also reduces the overall reliability of the ice-making system.

[0033] Regarding the problems in related technologies, such as Figures 1-4 As shown, this utility model provides a refrigerator, including a water tank body 10 and a water tank support 20. The water tank support 20 is provided with a receiving groove 21 for accommodating the water tank body 10. The bottom wall of the water tank body 10 is provided with a first limiting part 101, and the bottom wall of the receiving groove 21 is correspondingly provided with a second limiting part 210 that cooperates with the first limiting part 101. The cooperation between the first limiting part 101 and the second limiting part 210 restricts the horizontal movement of the water tank body 10 within the receiving groove 21. The ice-making system in the refrigerator requires the injection of water for ice making into the water tank body 10, which places relatively flexible requirements on the water tank body 10. In this embodiment, the cooperation of the first limiting part 101 and the second limiting part 210 achieves the limitation of the water tank body 10. This limiting cooperation effectively reduces the precision requirements of the components, thereby reducing the complexity of the mold and lowering the overall manufacturing cost of the product. Furthermore, this limiting cooperation effectively improves the overall service life and reliability of the product.

[0034] Specifically, such as Figure 2 As shown, the water tank body 10 is constructed as a long and flat box structure with a water storage space inside. The water tank bracket 20 is used to accommodate and support the water tank body 10. The water tank bracket 20 is connected to the main structure of the refrigerator through the embedded part 30 or other components, so that the position of the water tank body 10 is stable and water can be added stably.

[0035] The width of the receiving groove 21 is slightly greater than or equal to the width of the water tank body 10, which facilitates the installation of the water tank body and enables effective positioning through the receiving groove 21.

[0036] In a specific configuration, the first limiting part 101 and the second limiting part 210 engage in a cooperative manner to achieve the limiting position. For example, this can be achieved through a combination of magnetic attraction and a positioning post. Specifically, the first limiting part 101 has a protruding positioning post structure, with a ring-shaped neodymium magnet wrapped around the base of the positioning post. A positioning hole is correspondingly provided at the bottom of the receiving groove 21, and an iron-nickel alloy sheet is provided at the bottom of the positioning hole. Coordination and limiting are achieved through magnetic attraction. Other limiting structures are also possible, such as a snap-fit ​​limiting structure or a limiting structure where a boss and a groove engage. See the following embodiments for details.

[0037] Understandably, by employing the cooperation of two limiting parts, the drawbacks of excessive cost and short service life associated with sliding fit structures are avoided. In other words, the method in this embodiment, through the cooperation of two limiting parts, effectively reduces the processing and manufacturing difficulty of components and lowers the overall manufacturing cost of the product.

[0038] In some embodiments, such as Figure 2 , Figure 4 As shown, the first limiting part 101 includes a limiting boss disposed on the bottom wall of the water tank body 10, and the second limiting part 210 includes a limiting groove disposed on the bottom wall of the receiving groove 21. After the water tank body 10 is filled with water, its overall center of gravity is located above the receiving groove 21. In order to maintain the stability of the water inside, it is necessary to limit the overall position of the water tank body 10 to avoid horizontal displacement and shaking. This embodiment can effectively achieve the limiting by using the limiting boss and the limiting groove, and this method can effectively reduce the manufacturing cost of the product.

[0039] Specifically, on the one hand, the combination of the limiting boss and the limiting groove can effectively achieve limiting and facilitate the installation and removal of the water tank body 10. On the other hand, the boss and the water tank body 10, as well as the limiting groove and the receiving groove 21, are all formed in one step by injection molding, without the need for subsequent processing (such as drilling or bonding). Moreover, the boss / groove structure only modifies the mold cavity and does not increase the number of mold sets, which can effectively reduce the cost of forming the structure and thus reduce the overall cost of the product.

[0040] Understandably, the limiting boss and the limiting groove have matching shapes and dimensions to prevent the limiting boss from wobbling circumferentially after it is engaged with the limiting groove. For example, if the limiting boss is a long, rectangular structure, the corresponding limiting groove should be a square, recessed groove. If the limiting boss is a trapezoidal columnar structure, the corresponding limiting groove should be a trapezoidal groove to achieve the desired fit.

[0041] In conjunction with the above embodiments, such as Figure 4 , Figure 5 As shown, a limiting groove 102 is formed inside the water tank body 10 at the position corresponding to the limiting boss. The limiting groove 102 is used to accommodate the water pump (not shown in the figure) installed inside the water tank body 10 and restrict the horizontal movement of the water pump. The water pump installed inside the water tank body 10 is used to transport the water stored inside to the ice maker to realize the ice making operation. In conventional equipment, the water pump is usually installed in an open installation method. This method is prone to improper installation. When improperly installed, the water pump will generate a lot of noise when it is working. In this embodiment, the setting of the limiting groove 102 can effectively limit the water pump body, effectively prevent improper installation, and thus improve the stability of the overall structure.

[0042] Specifically, a limiting groove 102 is formed by the downward indentation of the bottom wall of the water tank body 10, and a limiting boss is formed on the bottom wall of the water tank body 10. The limiting boss can cooperate with the limiting groove to achieve limiting, while the limiting groove 102 can effectively limit the water pump and avoid the situation of improper installation.

[0043] During installation, the pump body needs to be located at the lowest point of the bottom wall of the water tank body 10, specifically at the lowest point of the limiting groove 102. The structural dimensions of the limiting groove 102 are approximately the same as those of the pump body, ensuring that the pump can be precisely installed within the limiting groove 102, effectively preventing improper installation.

[0044] In conjunction with the above embodiments, such as Figure 5 As shown, the limiting trough 102 includes a first sidewall 103 and a second sidewall 104 disposed opposite to each other; the first sidewall 103 has a contoured stepped portion for cooperating with part of the pump body structure of the water pump; the second sidewall 104 has a ramp structure. The limiting trough 102 is located inside the water tank body 10 and needs to limit the water pump. In this embodiment, the cooperation of the contoured stepped portion and the ramp structure facilitates the installation of the water pump and makes the water pump more stable.

[0045] Specifically, the first sidewall 103 and the second sidewall 104 are located along the length of the water tank body 10. The limiting groove 102 and the limiting boss are located at one end along the length of the water tank body 10. This allows the limiting boss to effectively prevent the water tank body 10 from shaking after it cooperates with the limiting groove. Furthermore, the contoured step in the limiting groove 102 can cooperate with the corresponding structure on the water pump to achieve stable limiting of the water pump.

[0046] Furthermore, the ramp structure provides guidance during the installation of the water pump, which facilitates the installation process.

[0047] Understandably, the structural constraints on the two opposite sidewalls of the limiting trough 102 facilitate the installation of the water pump and provide a stable limiting effect after the water pump is installed, thus making the water pump assembly more stable.

[0048] In some embodiments, such as Figure 4 As shown, the water tank body 10 also includes a water tank cover 11, which has a water inlet. A flip cover 110 is hinged to the water inlet via a pivot. Ice water needs to be added to the water tank body 10 periodically. In this embodiment, the flip cover 110 allows the water inlet to be opened and closed, and the overall manufacturing cost of the water tank is reduced by using the flip cover.

[0049] Specifically, the flip cover 110 can completely cover the water inlet, and a sealing strip is set around the edge of the water inlet so that the flip cover 110 can seal the water inlet when the body is closed.

[0050] Understandably, in related technologies, the water tank cover 11 usually adopts a sliding cover method to open and close the water inlet. The sliding cover method increases the cost of the product. In this embodiment, the flip cover 110 can effectively reduce the production cost of the product.

[0051] In some embodiments, such as Figure 6 , Figure 7 As shown, the receiving tank 21 has a first limiting sidewall 22 and a second limiting sidewall 23 disposed opposite to each other, and the outer wall of the second limiting sidewall 23 has a notch structure 231 to form a loading and unloading notch for loading and unloading the water tank body 10 on the side of the receiving tank 21 near the second limiting sidewall 23. The water tank body 10 needs to have a stable structure after water is added and when the water pump is working. In this embodiment, the cooperation of the first limiting sidewall 22 and the second limiting sidewall 23 makes the limiting of the water tank body more stable.

[0052] Specifically, the coverage area of ​​the first limiting sidewall 22 is greater than that of the second sidewall 104, and both the first limiting sidewall 22 and the second limiting sidewall 23 have inclined bevel structures on the edge near the opening of the limiting groove. Thus, the two limiting sidewalls cooperate to form a parallelogram-like loading and unloading notch, which facilitates the loading and unloading of the water tank body 10.

[0053] It is understandable that the water tank body 10 is usually installed on the inner liner of the refrigerator. In order not to affect the internal storage space, it is usually set relatively compactly. In this embodiment, the structure of the loading and unloading notch can facilitate manual force application, thereby facilitating the installation and disassembly of the water tank body 10.

[0054] In conjunction with the above embodiments, such as Figure 6 As shown, along the direction perpendicular to the inner wall surface of the first limiting sidewall 22, the ratio of the overlapping area of ​​the projected area of ​​the first limiting sidewall 22 and the projected area of ​​the water tank body 10 is greater than 0.5. After the water tank body 10 is filled with water, it needs to have a stable limiting environment. In this embodiment, by limiting the projected area of ​​the first sidewall 103, the contact area between the first limiting sidewall 22 and the water tank body is larger, thereby providing a more stable limiting environment.

[0055] It is understandable that when the water tank body is filled with ice-making water, its overall weight increases. During the ice-making process, the shaking may affect the limiting stability of the water tank body 10. In this embodiment, the limiting stability can be improved by increasing the contact area between the first side wall 103 and the water tank body.

[0056] In some embodiments, a pre-embedded part 30 is also included, and a snap-fit ​​structure 24 is provided between the pre-embedded part 30 and the water tank bracket 20. The water tank bracket 20 is disposed on one side of the pre-embedded part 30 through the snap-fit ​​structure 24. The pre-embedded part 30 is disposed on the inner liner of the refrigerator, and the water tank bracket 20 is connected and snapped together through the snap-fit ​​structure 24, which facilitates the installation of the water tank bracket 20.

[0057] Specifically, the embedded part 30 is embedded in the inner liner of the refrigerator, and the water tank bracket 20 is used to support the entire water tank body 10. A snap-fit ​​structure 24 is provided between the water tank bracket 20 and the embedded part 30, such as a snap-fit ​​structure 24 or a slot-fit structure 24. The snap-fit ​​structure 24 can facilitate the connection and positioning of the water tank bracket 20.

[0058] Furthermore, in order to improve the stability of the water tank bracket 20 connection, screw holes are provided on the water tank bracket 20, so that it can be made more stable by screw connection.

[0059] In conjunction with the above embodiments, such as Figure 4 , Figure 9As shown, the system also includes a funnel assembly 40, which comprises a funnel body 41 and a guide pipe 42. The funnel body 41 is connected to the embedded part 30 via a snap-fit ​​structure and is located on one side of the water tank body 10. The water tank body 10 is provided with a water outlet pipe 12, one end of which is connected to a water pump inside the water tank body 10, and the other end of which is located above the funnel body 41. The guide pipe 42 is connected to the outlet end of the funnel body 41. The snap-fit ​​structure includes snap-fit ​​spring pieces 43 located near the bottom and top of the funnel body 41. The embedded part 30 is provided with a snap-fit ​​groove and a pre-embedded channel 31. The snap-fit ​​groove engages with the snap-fit ​​spring pieces 43, and the guide pipe 42 extends out from the pre-embedded channel 31. The funnel body 41 is used for the transmission of ice-making water. In this embodiment, by providing snap-fit ​​spring pieces 43 at the top and bottom of the side wall of the funnel body 41, the installation of the funnel body 41 becomes more stable, improving the overall stability.

[0060] In the overall water system, the ice-making water in the water tank 10 is output by a water pump, input into the funnel body 41 through the outlet pipe 12, output through the guide pipe 42 after passing through the funnel body 41, and finally delivered to the ice maker to realize the ice-making operation.

[0061] In this embodiment, snap-fit ​​spring pieces 43 are provided at the top and bottom of the side wall of the funnel body 41. This makes the force on the funnel body 41 uniform when it is idle and during water transmission, avoiding the skewing of the funnel body 41 during installation and operation, and improving the stability of the overall structure.

[0062] In specific settings, such as Figure 8 As shown, a connecting pipe is also provided at the output port of the pre-embedded channel 31. The connecting pipe is connected to the ice maker to realize the ice making operation.

[0063] It is understandable that the funnel body 41 experiences significantly different forces in its working and idle states, especially when the input of ice-making water increases, resulting in a certain impact force. In this embodiment, the stability can be effectively improved by using two sets of snap-fit ​​spring clips 43.

[0064] In conjunction with the above embodiments, such as Figure 7 As shown, it also includes a bus box. A mounting groove 221 is provided on the side wall of the water tank bracket 20 where it connects to the embedded part 30. The mounting groove 221 is used to install the bus box 50. A limiting buckle 222 is provided on the side wall of the mounting groove 221, corresponding to a card interface on the bus box. The water pump and other internal components such as the motor need to be connected to the wiring harness. In this embodiment, modular installation can be achieved through the bus box. Each wiring harness leading out from the bus box has a plug-in terminal, which enables circuit continuity, thus facilitating the management of the overall wiring harness.

[0065] Specifically, a wire harness opening 223 is provided on one side of the mounting slot 221. The wire harness opening 223 is used for multiple wire harnesses to pass through. A limiting buckle 222 is provided on one side of the wire harness opening 223. The limiting buckle 222 facilitates the installation of the bus box and maintains the stability of the bus box.

[0066] Through the above description of the embodiments, those skilled in the art can clearly understand that the cooperation between the first limiting part 101 and the second limiting part 210 of the refrigerator in each embodiment achieves the limiting of the water tank body 10. The limiting cooperation method can effectively reduce the precision requirements of the components, thereby reducing the complexity of the mold and reducing the overall manufacturing cost of the product. Moreover, the limiting cooperation method can effectively improve the overall service life and reliability of the product.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
