The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0019] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0020] Please see Figure 1 and Figure 2 , Figure 1 The ice maker 1000 shown omits the top outer shell. This application embodiment provides an evaporator shaping device 100, which is used to correct and shape the evaporator 300 that has been assembled and deformed in the ice maker 1000, so that the evaporator 300 can maintain a suitable posture and shape to ensure the ice-making effect.

[0021] Furthermore, the ice maker 1000 includes an inner liner assembly 200 and an evaporator 300. The space above the inner liner assembly 200 is the ice-making area 201, and the evaporator 300 is disposed in the ice-making area 201. When the evaporator 300 is installed in the ice-making area 201, the top outer casing of the ice maker 1000 (such as...) has not yet been installed. Figure 1As shown), the top of the inner liner assembly 200 has a flat surface 202 for placing the evaporator shaping device 100, and a snap-fit ​​structure 203 for fastening and connecting with the outer casing of the ice maker 1000. The snap-fit ​​structure 203 can also be connected with the evaporator shaping device 100 to have a limiting function, so as to facilitate the shaping operation of the evaporator shaping device 100.

[0022] The evaporator 300 consists of a main pipe 301 and a cooling head 302. The main pipe 301 connects to the inlet and outlet pipes and capillary tubes. Due to material handling or welding issues, the main pipe 301 may be significantly misaligned, causing the cooling head 302 to be too low, too high, or tilted, leading to problems such as ice buildup, excessively short ice particles, and misaligned ice particles. Therefore, the main pipe 301 of the evaporator 300 needs to be reshaped during the production and assembly process.

[0023] Please refer to this as an example. Figure 3 The evaporator shaping device 100 includes a support plate 10, a pry bar 20, and a pressure bar 30. The support plate 10 has a plate-like structure, and the pry bar 20 has a mounting groove 221. The support plate 10 is partially inserted into the mounting groove 221, and the extension direction of the pry bar 20 is perpendicular to the length direction X of the support plate 10. The pressure bar 30 is rotatably connected to the pry bar 20. The pry bar 20 is used to pry up the downward deformed evaporator 300, and the pressure bar 30 is used to press down the upward deformed evaporator 300.

[0024] With the above structural arrangement, the support plate 10 is connected to the pry bar 20 to form a support structure for the pry bar 20, so that the pry bar 20 can rotate relative to the inner liner assembly 200 to pry up the deformed evaporator 300. The pressure bar 30 is rotatably connected to the pry bar 20, so that the pressure bar 30 can rotate relative to the inner liner assembly 200 to press down the deformed evaporator 300. In this way, the evaporator shaping device 100 can restore the deformed evaporator 300 to ensure the ice-making effect.

[0025] In some embodiments, please refer to Figure 3 The pry bar 20 includes a first gripping part 21, a plugging part 22, and a prying part 23 connected together. The plugging part 22 is disposed between the first gripping part 21 and the prying part 23, and the plugging part 22 has a mounting groove 221 extending through it along the length X of the support plate 10. The pressure bar 30 includes a second gripping part 31 and a pressing part 32 connected together. The end of the pressing part 32 away from the second gripping part 31 is rotatably connected to the prying part 23; as Figure 1 and Figure 2 As shown, when the lifting part 23 and the pressing part 32 are arranged opposite to each other, a shaping space Q1 is formed, which is used to accommodate the evaporator 300.

[0026] Combination Figure 1As shown, the support plate 10 spans the top plane 202 of the inner liner assembly 200. The support plate 10 is connected to the pry bar 20, and the support plate 10 constitutes a rotational support structure for the pry bar 20. Along the width direction Y of the support plate 10, the support plate 10 has a first side portion 11 and a second side portion 12, wherein the first side portion 11 is close to the prying portion 23, and the second side portion 12 is close to the first grip portion 21.

[0027] Please see Figure 4 and Figure 5 During the shaping of the evaporator 300, the pressure rod 30 can be rotated above the pry bar 20 first. By adjusting the angle of the pry bar 20, the prying part 23 can be inserted below the main pipe 301 of the evaporator 300. Figure 5 As shown, if the initial orientation of the evaporator 300 is downward deformation, the prying part 23 abuts against the lower part of the main pipe 301 of the evaporator 300, and the support plate 10 is tilted and pried up relative to the inner liner assembly 200. That is, the first side 11 of the support plate 10 abuts against the top plane 202 of the inner liner assembly 200, and the second side 12 separates from the top plane 202 of the inner liner assembly 200. By pressing down the first gripping part 21, under the support of the support plate 10, the prying part 23 pushes the main pipe 301 of the evaporator 300 upward and resets it until the second side 12 of the support plate 10 is in contact with the top plane 202 of the inner liner assembly 200.

[0028] like Figure 6 As shown, if the initial orientation of the evaporator 300 is upward deformation, the support plate 10 can be placed flat on the top plane 202 of the inner liner assembly 200, that is, the first side 11 and the second side 12 of the support plate 10 both abut against the top plane 202 of the inner liner assembly 200. By rotating the pressure rod 30 in the opposite direction, the pressure rod 30 is positioned above the main pipe 301 of the evaporator 300. Continuing to press down the second gripping part 31, the pressing part 32 presses down and resets the main pipe 301 of the evaporator 300.

[0029] In this embodiment, by providing a support plate 10 with a certain width, firstly, the structural strength of the support plate 10 can be enhanced, the deformation of the support plate 10 during the rotation of the pry bar 20 can be reduced, and the shaping accuracy can be guaranteed. Secondly, the rotation angle of the pry bar 20 can be limited, thereby limiting the degree of correction of the evaporator main pipe 301 by the prying part 23, and preventing incomplete or excessive correction. Specifically, the posture of the evaporator 300 when the first side 11 and the second side 12 of the support plate 10 are both attached to the top plane 202 of the inner liner assembly 200 is the normal working state of the evaporator 300.

[0030] In some embodiments, please refer to Figure 3The first side 11 of the support plate 10 is close to the prying part 23. The first side 11 is provided with a second arc-shaped surface 111, which is used for the support plate 10 to rotate in contact with the external structure. As an example, the second arc-shaped surface 111 is used to abut against the top plane 202 of the inner liner assembly 200 to facilitate the adjustment of the angle at which the pry bar 20 is inserted obliquely into the main pipe 301 of the evaporator 300, and to facilitate the rotation of the support plate 10 relative to the inner liner assembly 200 when the pry bar 20 pries the main pipe 301 of the evaporator 300 upward.

[0031] In some embodiments, please refer to Figure 2 and Figure 6 The first side 11 of the support plate 10 is close to the prying part 23. The first side 11 has a groove 112 for connecting with an external structure to limit the position of the support plate 10. As an example, the top of the inner liner assembly 200 has a snap-fit ​​structure 203 for fastening with the outer shell of the ice maker 1000. The groove 112 on the first side 11 allows the groove 112 to be adapted to the snap-fit ​​structure to achieve the positioning of the support plate 10 relative to the inner liner assembly 200, preventing the support plate 10 from sliding in its length direction X or width direction Y during the shaping process, thus affecting the shaping effect.

[0032] In some embodiments, please refer to Figure 3 The pry bar 20 also includes an inclined portion 24, which connects the insertion portion 22 and the prying portion 23. A pressing portion 32 is rotatably connected between the inclined portion 24 and the prying portion 23. Specifically, the inclined portion 24 extends inclined downwards toward the insertion portion 22, so that the prying portion 23 is located below the insertion portion 22. By providing the inclined portion 24, the pry bar 20 can better adapt to the installation position of the evaporator 300 in the inner liner assembly 200, further improving the alignment accuracy.

[0033] In some embodiments, please refer to Figure 3 and Figure 6 The pressure rod 30 also includes a limiting part 33, which connects the second gripping part 31 and the pressing part 32. The limiting part 33 is used to abut against the external structure to limit the movement stroke of the pressing part 32. As an example, the limiting part 33 forms a stepped structure. When the pressure rod 30 is rotated to press down and shape the main pipe 301 of the upwardly deformed evaporator 300, if the limiting part 33 does not abut against the top plane 202 of the inner tank assembly 200, it means that the evaporator 300 has not been shaped properly and further pressing is required until the limiting part 33 abuts against the top plane 202 of the inner tank assembly 200. At this point, it means that the evaporator 300 has been shaped properly, preventing further pressing from causing the main pipe 301 of the evaporator 300 to deform downward and resulting in over-correction.

[0034] In some embodiments, please refer to Figure 3and Figure 6 The pressing part 32 extends towards the prying part 23 with a boss 321. The boss 321 has first arc-shaped surfaces 322 on both sides, which are used to fit and abut against the evaporator 300. The main pipe 301 of the evaporator 300 is typically curved to form a loop. Therefore, by providing the boss 321 structure and having the first arc-shaped surfaces 322 on both sides fit against the outer wall of the main pipe 301, the main pipe 301 can be prevented from being flattened, thus affecting the ice-making effect. Furthermore, the boss 321 fits between the two main pipes 301 of the evaporator 300, allowing for further adjustment of the distance between the two main pipes 301, preventing them from getting too close to each other during the shaping process and affecting the ice-making effect.

[0035] In some embodiments, please refer to Figure 3 A first buffer pad 25 is provided on the side of the lifting part 23 facing the pressing part 32; and / or, a second buffer pad 34 is provided on the side of the pressing part 32 facing the lifting part 23. By providing the buffer pad structure, damage to the main pipe 301 of the evaporator 300 by the lifting part 23 or the pressing part 32 can be further avoided.

[0036] In some embodiments, please refer to Figure 3 The pry bar 20 is provided with a first reinforcing rib 26, which connects the insertion part 22 and the first gripping part 21. During the pressing down of the first gripping part 21, the first reinforcing rib 26 reduces the deformation of the first gripping part 21 relative to the insertion part 22, ensuring a shaping effect. And / or, the upper side of the pressing part 32 is provided with a second reinforcing rib 35. During the pressing down of the second gripping part 31, the pressing part 32 compresses the main pipe 301 of the evaporator 300. The second reinforcing rib 35 enhances the structural strength of the pressing part 32, ensuring a shaping effect.

[0037] In some embodiments, please refer to Figure 3 and Figure 4 The support plate 10 is fitted with the insertion part 22 in the mounting groove 221, allowing the pry bar 20 to move relative to the support plate 10 along its length direction X. This allows for reshaping and adjusting the main pipe 301 of the evaporator 300 at different positions, providing a flexible structure. Furthermore, the movement of the pry bar 20 relative to the support plate 10 also allows the evaporator shaping device 100 to adapt to evaporators 300 of different sizes. In other embodiments, multiple pry bars 20 and multiple pressure rods 30 are used. Multiple pry bars 20 are mounted on the support plate 10, with one pressure rod 30 rotatably connected to one pry bar 20 to reshape the main pipe 301 of the evaporator 300 at different positions, improving shaping efficiency.

[0038] In some embodiments, please refer to Figure 3 and Figure 4The insertion part 22 is provided with a fixing hole 222, which connects to the mounting groove 221. The evaporator shaping device 100 also includes a fastener 40, which is connected to the support plate 10 through the fixing hole 222 to fix the pry bar 20 to the support plate 10. As an example, the fixing hole 222 is a screw hole, and the fastener 40 is a bolt. The bolt is screwed into the screw hole. By tightening the bolt, the end of the bolt abuts against the support plate 10, at which time the pry bar 20 is fixed relative to the support plate 10; by tightening the bolt, the end of the bolt moves away from the support plate 10, at which time the pry bar 20 can move relative to the support plate 10.
