Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0038] Next, the embodiments of this specification are described in detail.

[0039] The present application provides a refrigerator, comprising a freezing part (not shown), a refrigerating part (not shown) and an ice maker (not shown). The ice makers are respectively arranged in the freezing part and the refrigerating part. The refrigerator of the present application can increase the ice making capacity of the refrigerator, enrich the use functions of the refrigerator, and improve people's use experience and market competitiveness by arranging the ice maker.

[0040] The present application also provides an ice-making machine as described above, which includes an anti-mistake installation structure to improve the assembly efficiency of the ice-making machine.

[0041] The present application also provides an error-proof installation structure as described above. Figures 1 to 4 As shown, the error-proof installation structure of the present application includes a first mounting member 1, a second mounting member 2, a first matching member 3 and a second matching member 4. The first mounting member 1 is assembled with the first matching member 3, and the second mounting member 2 is assembled with the second matching member 4. The first mounting member 1 and the second mounting member 2 are similar parts to each other, and the first matching member 3 and the second matching member 4 are similar parts to each other.

[0042] In one embodiment, the first mounting member 1 includes a first protrusion 11 (see Figure 1 The first matching member 3 includes a first avoidance portion 31 (see Figure 2 The first protrusion 11 cooperates with the first avoidance portion 31 so that the first mounting member 1 can only cooperate with the first matching member 3. This arrangement effectively prevents the first mounting member 1, the second mounting member 2, the first matching member 3 and the second matching member 4 from being misassembled, thereby saving assembly time and improving work efficiency.

[0043] In one embodiment, the first mounting member 1 and the second mounting member 2 are components with similar outer contours, the first protrusion 11 is located at the corner of the first mounting member 1, and the position of the second mounting member 2 corresponding to the corner of the first mounting member 1 is a groove 22. The first matching member 3 and the second matching member 4 are components with similar inner contours, that is, the position where the first matching member 3 matches the first mounting member 1 and the position where the second matching member 4 matches the second mounting member 2 are similar areas. The first avoidance portion 31 is located at the corner of the first matching member 3 to accommodate the first protrusion 11. The position of the second matching member 4 corresponding to the corner of the first matching member 3 is a convex block 45, and the convex block 45 matches the groove 22.

[0044] Since the first mounting member 1 is provided with the first protrusion 11 at the corner, and in order to prevent the first protrusion 11 from conflicting with other components, such as the protrusion 45, during installation, the first mounting member 1 can only be provided on the first matching member 3. If the first mounting member 1 is provided on the second matching member 4, the first protrusion 11 will conflict with the protrusion 45, and the first mounting member 1 cannot be smoothly installed. Such a configuration can prevent wrong installation, thereby saving assembly time and improving work efficiency.

[0045] Since the groove 22 at the corner of the second mounting member 2 does not conflict with the first avoidance portion 31, the second mounting member 2 can be matched with the first matching member 3 in addition to the second matching member 4. In this way, the installation position of the second mounting member 2 can be increased to meet the installation requirements of multiple second mounting members 2.

[0046] like Figures 5 to 10 As shown, in one embodiment, the error-proofing installation structure includes a mounting substrate 5. The first mounting member 1 and the second mounting member 2 are respectively arranged on the mounting substrate 5, and in the height direction of the mounting substrate 5, part of the first mounting member 1 is located above the second mounting member 2. The second mounting member 2 includes a second protruding portion 21, and the second matching member 4 includes a second avoiding portion 41. In the height direction of the mounting substrate 5, the first protruding portion 11 is located above the second protruding portion 21. The second protruding portion 21 cooperates with the second avoiding portion 41, so that the second matching member 4 is smoothly assembled on the second mounting member 2.

[0047] In this embodiment, the difference between the first mounting member 1 and the second mounting member 2 is only that the position of the first protrusion 11 on the first mounting member 1 is different from the position of the second protrusion 21 on the second mounting member 2. Fig. 9 and Fig.10 After the first matching piece 3 and the second matching piece 4 are matched with the first mounting piece 1 and the second mounting piece 2, the first matching piece 3 and the second matching piece 4 are arranged flush with each other in the height direction of the mounting substrate 5 to save the installation space.

[0048] Further, the first matching piece 3 includes a first main body 32, and the second matching piece 4 includes a second main body 42. The first main body 32 and the second main body 42 are mirror images of each other, and the difference between the first matching piece 3 and the second matching piece 4 lies in the first avoidance portion 31 and the second avoidance portion 41.

[0049] Specifically, the first main body 32 and the second main body 42 are both provided with a support end 321. The first avoidance portion 31 extends downward from the support end 321 on the first main body 32. The second avoidance portion 41 extends downward from the support end 321 on the second main body 42. And in the direction from top to bottom of the mounting substrate 5, the second avoidance portion 41 extends downward beyond the first avoidance portion 31, and the second protrusion 21 is located at the portion where the second avoidance portion 41 exceeds the first avoidance portion 31, that is, the second protrusion 21 is located below the first avoidance portion 31.

[0050] With such arrangement, if the first mating component 3 is mistakenly arranged on the second mounting component 2, since the second protrusion 21 is located below the first avoidance portion 31, the first mating component 3 cannot avoid the second protrusion 21, and the second protrusion 21 will press against the first main body portion 32, thereby making it impossible to install, thereby achieving the purpose of preventing the first mating component 3 from being installed incorrectly.

[0051] The first main body 32 and the second main body 42 each include a first bottom plate 322 and a second bottom plate 323 connected to the first bottom plate 322. The first avoidance portion 31 is located on the first bottom plate 322 and the second bottom plate 323, and the second avoidance portion 41 is located on the first bottom plate 322. In the width direction of the mounting substrate 5, the first protrusion 11 is located at the connection between the first bottom plate 322 and the second bottom plate 323, and the second protrusion 21 is located in the middle area of ​​the first bottom plate 322.

[0052] Specifically, in the height direction of the mounting substrate 5 , the projection of the first protrusion 11 covers the projection of the connection between the first bottom plate 322 and the second bottom plate 323 , and the projection of the second protrusion 21 overlaps with the projection of a portion of the first bottom plate 322 .

[0053] With such arrangement, if the second matching member 4 is mistakenly installed on the first mounting member 1, since the second avoiding portion 41 is only located on the first bottom plate 322, it cannot avoid the first protruding portion 11, and the first protruding portion 11 will hit the second bottom plate 323, thereby making it impossible to install, thereby achieving the purpose of preventing the second matching member 4 from being wrongly installed. In summary, the first matching member 3 can be correctly installed on the first mounting member 1, and the second matching member 4 can be correctly installed on the second mounting member 2, thereby saving time and improving work efficiency.

[0054] The first avoidance portion 31 and the second avoidance portion 41 are each an avoidance space, the first protrusion 11 extends into the first avoidance portion 31, and a portion of the first protrusion 11 exceeds the first bottom plate 322. The second protrusion 21 extends into the second avoidance portion 41, and a portion of the second protrusion 21 exceeds the first bottom plate 322.

[0055] The first protrusion 11 includes a first nozzle 111 and a first baffle 112. Part of the first nozzle 111 and the first baffle 112 are located in the first avoidance portion 31, and the first baffle 112 is located between the first nozzle 111 and the bottom side of the first avoidance portion 31. In this way, the first baffle 112 is used to block the bottom side of the first avoidance portion 31 to prevent the bottom side of the first avoidance portion 31 from hitting the first nozzle 111 and damaging the first nozzle 111 when the first matching member 3 is installed.

[0056] The second protrusion 21 includes a second nozzle 211 and a second baffle 212. Part of the second nozzle 211 and the second baffle 212 are located in the second avoidance portion 41, and the second baffle 212 is located between the second nozzle 211 and the bottom side of the second avoidance portion 41. In this way, the second baffle 212 is used to block the bottom side of the second avoidance portion 41 to prevent the bottom side of the second avoidance portion 41 from hitting the second nozzle 211 and damaging the second nozzle 211 when the second matching member 4 is installed.

[0057] like Figures 11 to 16As shown, in one embodiment, the first mating piece 3 and the second mating piece 4 are respectively fixedly arranged on the mounting substrate 5. Preferably, the first mating piece 3 and the second mating piece 4 are integrally formed with the mounting substrate 5. The first mating piece 3 includes a first main body portion 32, a first anti-error column 33 and a first interpenetrating portion, and the second mating piece 4 includes a second main body portion 42 and a second anti-error column 43. The first main body portion 32 and the second main body portion 42 are mirror images of each other.

[0058] Furthermore, the first error prevention column 33 is located in the middle area of ​​the first main body 32, and the second error prevention column 43 is located in the tail area of ​​the second main body 42. The first main body 32 includes a first insertion portion 324, and the second main body 42 includes a second insertion portion 421. On the first mating member 3, the space between the first insertion portion 324 and the first error prevention column 33 is the first avoidance portion 31, as shown in FIG. Fig.13 On the second fitting 4, the space between the second insertion portion 421 and the second error prevention column 43 is the second avoidance portion 41, as shown in the dashed box. Fig.13 Shown in the dashed box.

[0059] In this embodiment, the difference between the first mounting member 1 and the second mounting member 2 is that the first mounting member 1 is provided with a third anti-error column 12, and the position of the first protrusion 11 on the first mounting member 1 is different from the position of the second protrusion 21 on the second mounting member 2. The difference between the first mating member 3 and the second mating member 4 is that the position of the first anti-error column 33 on the first mating member 3 is different from the position of the second anti-error column 43 on the second mating member 4.

[0060] In the length direction of the first mating piece 3 or the second mating piece 4, the projection of the first error proofing column 33 overlaps with the projection of the first protrusion 11 and the third error proofing column 12, respectively, and the projection of the second error proofing column 43 overlaps with the projection of the second protrusion 21. The first error proofing column 33 and the second error proofing column 43 are mirror images of each other. The third error proofing column 12 corresponds to the tail area of ​​the first main body 32, and the second protrusion 21 corresponds to the middle area of ​​the second main body 42.

[0061] Such arrangement ensures that when the first mounting part 1, the second mounting part 2, the first matching part 3 and the second matching part 4 are installed incorrectly, a position conflict will occur between the parts, thereby providing a reminder for incorrect installation. Specifically, if the first mounting part 1 is installed incorrectly on the second matching part 4, due to the different areas of the first avoidance part 31 and the second avoidance part 41, the second anti-error column 43 abuts against the third anti-error column 12 to prevent the first mounting part 1 from being installed, thereby providing a reminder for incorrect installation. If the second mounting part 2 is installed incorrectly on the first matching part 34, due to the different areas of the first avoidance part 31 and the second avoidance part 41, the first anti-error column 33 abuts against the second protrusion 21 to prevent the second mounting part from being installed, thereby providing a reminder for incorrect installation.

[0062] The first protrusion 11 and the second protrusion 21 are both quick-insertion tube heads. Part of the first protrusion 11 extends into the first insertion portion 324. The second protrusion 21 and the second insertion portion 421 are arranged at intervals. Through such an arrangement, it is possible to determine whether the first mounting member 1, the second mounting member 2, the first matching member 3 and the second matching member 4 are incorrectly installed by checking the positional relationship between the first protrusion 11 and the first insertion portion 324 and the positional relationship between the second protrusion 21 and the second insertion portion 421.

[0063] In the error-proof installation structure of the present application, the first mounting member 1 and the second mounting member 2 are water injection end assemblies or ice trays, and the first matching member 3 and the second matching member 4 are accommodating shells or ice tray hanging boxes that cooperate with the water injection end assembly.

[0064] In the anti-misinstallation structure of the present application, the second mounting member 2 can be matched with the second matching member 4, and the first mounting member 1 and the first matching member 3 can be matched through the first protrusion 11 and the first avoidance portion 31, so that the first mounting member 1 can only be assembled with the first matching member 3, thereby ensuring that when the first mounting member 1 and the second mounting member 2 are assembled with the first matching member 3 and the second matching member 4, the special assembly relationship between the first protrusion 11 and the first avoidance portion 31 effectively prevents the first mounting member 1, the second mounting member 2, the first matching member 3 and the second matching member 4 from being misassembled, thereby saving time and improving work efficiency.

[0065] In the error-proof installation structure of the present application, the Z axis represents the height direction of the installation substrate 5, and the direction from top to bottom of the installation substrate 5 is the negative direction of the Z axis, and the X axis represents the width direction of the installation substrate 5. Figure 5 The length direction of the first matching piece 3 or the second matching piece 4 is Fig.14 As shown by the middle arrow A, the length direction of the first matching component 3 or the second matching component 4 is inclined relative to the height direction of the mounting substrate 5 or the width direction of the mounting substrate 5 .

Although the present application has been disclosed as a preferred embodiment as above, it is not used to limit the present application. Any technician familiar with this profession can use the technical content disclosed above to make some changes or modify it into an equivalent embodiment of equivalent changes without departing from the scope of the technical solution of the present application.
