[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] In the prior art, after removing the water filling box from the ice maker, the user will then fill the water box with an appropriate amount of water and then replace the water filling box on the ice maker. Generally speaking, the water filling box needs to be placed flat on the ice maker to ensure that the water falls evenly onto the ice mold. Accordingly, the water inlet of the water filling box is set on a side parallel to the thickness direction to ensure the water filling amount. However, when the water filling box is replaced in the ice maker, the water inlet will also be placed horizontally. This requires the user to ensure that the water inlet is above the ice mold when installing the water filling box before laying the water filling box flat on the ice maker. Alternatively, after laying the water filling box flat on the ice maker, the user can slowly push the water filling box to the predetermined position while pushing the water filling box to the predetermined position. However, the above installation steps are very demanding for the user. Generally speaking, the user will inevitably deviate from the expected operation, which can cause the water in the water filling box to overflow or even spill outside the ice maker, causing ice contamination or reducing the ice production amount, affecting the ice making effect, and thus reducing the user's user experience.

[0037] The utility model provides a water filling box.

[0038] Please refer to Figures 1 to 3 In one embodiment of the present invention, the water filling box includes a first wall body 100 and a second wall body 200 that are opposite to and spaced apart from each other. The first wall body 100 and the second wall body 200 are jointly constructed to form a water filling chamber 500 and a water inlet 400 connected to the water filling chamber 500. The first wall body 100 is provided with a water outlet 110 connected to the water filling chamber 500. A water retaining portion 300 is protruded from one side of the first wall body 100 facing the second wall body 200, and the water outlet 110 and the water inlet 400 are respectively arranged on opposite sides of the water retaining portion 300.

[0039] The technical solution of the present invention is to open a water inlet 400 on a side wall between the first wall body 100 and the second wall body 200, the water inlet 400 is connected to the water injection chamber 500, and a water retaining portion 300 adjacent to the water inlet 400 is provided on the first wall body 100, and the water retaining portion 300 is protruded from the first wall body 100 provided with the water outlet 110 toward the second wall body 200. During the installation of the water filling box, the first wall 100 faces downward and the second wall 200 faces upward, and the water filling box is installed to the predetermined position by pushing the water filling box horizontally. At this time, the water retaining portion 300 will intercept the water flowing from the water filling chamber 500 toward the water inlet 400, thereby preventing the water in the water filling chamber 500 from overflowing from the water inlet 400. In this way, the user's concerns about the water in the water filling chamber 500 overflowing from the water inlet 400 can be reduced, and the water filling box can be installed to the predetermined position more conveniently, avoiding the situation where the overflow of water from the water filling chamber 500 increases the difficulty of cleaning and reduces the amount of ice making, thereby improving the user's experience.

[0040] It should be noted that the water inlet 400 is located on a side wall parallel to the thickness direction of the water filling box and extends in a direction perpendicular to the thickness direction. Similarly, in the extension direction parallel to the water inlet 400, the water retaining portion 300 also extends the same length as the water inlet 400, or at least extends to the two side walls of the water filling box opposite to each other along the extension direction of the water inlet 400. This ensures that water flowing from the water inlet 400 into the water filling chamber 500 can only flow through the gap between the water retaining portion 300 and the second wall 200, thereby intercepting water flowing from the water filling chamber 500 toward the water inlet 400. It can be understood that the water retaining portion 300 is located between the water inlet 400 and the water outlet 110, that is, to ensure that water in the water filling chamber 500 can only flow out through the water outlet 110 after flowing into the water filling chamber 500 through the water inlet 400. The location of the water outlet 110 is based on the maximum water injection volume required to be supplied by the water filling box and the distance between the first wall 100 and the second wall 200.

[0041] Among them, for the water filling box with the water inlet 400 at the same position, the relevant technology also includes setting a sealing cover at the water inlet 400. When a predetermined amount of water is injected into the water filling box, the sealing cover seals the water inlet 400, and then the water filling box is installed to the predetermined position. The water filling box of this technical solution does not need to be provided with a sealing cover, thereby reducing the operation of removing and installing the sealing cover on the water filling box and improving the convenience of adding water. In addition, during the installation of the water filling box, the water filling box is usually installed to the predetermined position by a flat push method. At this time, the opening direction of the water inlet 400 is generally the direction in which the water filling box is pushed. Of course, the opening direction of the water inlet 400 can also intersect with the direction in which the water filling box is pushed.

[0042] Regarding the forming method of the water retaining portion 300 on the first wall 100, in one embodiment, please refer to Figure 2 and Figure 3, the water retaining portion 300 and the first wall body 100 are integrally formed. It can be understood that the integral forming method can enhance the connection strength between the water retaining portion 300 and the first wall body 100, so that it can withstand multiple water flow impacts and ensure the reliability of the water retaining portion 300 placing the water in the water injection chamber 500 to prevent water from overflowing. At the same time, the water retaining portion 300 and the first wall body 100 are integrally formed, and the joint between the two is relatively tight, which reduces the possibility of water seeping out from the joint, and is beneficial to stabilizing the water level in the water injection box and preventing water from overflowing. In addition, the integral forming method of the water retaining portion 300 and the first wall body 100 simplifies the manufacturing process. Technicians can complete the production of the water retaining portion 300 and the first wall body 100 at the same time through a one-time molding process, without the need for additional assembly steps. In another embodiment, the water retaining portion 300 and the first wall body 100 are separately formed. It is understandable that the split molding method allows the water retaining portion 300 to be designed and manufactured independently of the first wall body 100, and technicians can adjust the shape, size and material of the water retaining portion 300 according to actual needs to meet different usage scenarios and performance requirements. At the same time, if the water retaining portion 300 is damaged or worn, the user or maintenance personnel only needs to remove the damaged water retaining portion 300 and then install a new water retaining portion 300 without replacing the entire water injection box. In addition, the design of the water injection box may require the water retaining portion 300 to have specific functions or characteristics (such as different materials, colors or surface treatments). The split molding method of the water retaining portion 300 and the first wall body 100 allows these specific needs to be realized without causing too much impact on the structure of the entire water injection box.

[0043] In one embodiment, please refer to Figure 2 、 Figure 3 and Figure 5The water retaining portion 300 includes a water retaining wall 310, which is arranged opposite to the water injection cavity 500 and extends between the first wall body 100 and the second wall body 200. It should be noted that the water retaining wall 310 is arranged in a plate shape, and the water inlet 400 is formed between the sides of the first wall body 100 and the second wall body 200, so that the water injection cavity 500 is a cavity with a uniform thickness or a similar uniform thickness. The water retaining wall 310 is arranged to protrude from the first wall body 100, so that the water retaining wall 310 can stably prevent water in the water injection cavity 500 from overflowing from the water inlet 400. In addition, the thickness of the connection between the water retaining wall 310 and the first wall body 100 is uniform, which can ensure the stability and sealing of the connection between the water retaining wall 310 and the first wall body 100, thereby ensuring the reliability of the water retaining wall 310 in intercepting the water flow from the water injection cavity 500 to the water inlet 400. Of course, in other embodiments, the water retaining portion 300 can also be configured as a convex rib, the extension direction of the convex rib is parallel to the extension direction of the water inlet 400, and is protruded from the first wall body 100 to the second wall body 200; or, in the side wall between the first wall body 100 and the second wall body 200, the opening position of the water inlet 400 is spaced a certain distance from the first wall body 100, and the water inlet 400 also extends toward the water injection chamber 500 with a water inlet section having a thickness less than the thickness of the water injection chamber 500, so that the water retaining portion 300 is formed as a water retaining step between the water injection chamber 500 and the water inlet 400, adjacent to the first wall body 100.

[0044] Further, in this embodiment, please refer to Figures 2 to 4 The water retaining portion 300 further includes a diversion wall 320, which is connected to the water retaining wall 310 and extends toward the water inlet 400. In the direction in which the diversion wall 320 extends, the distance between the diversion wall 320 and the second wall 200 gradually increases. It is understood that during the process of flowing from the water inlet 400 to the water injection chamber 500, the width of the flow channel corresponding to the diversion wall 320 gradually decreases in the direction in which the first wall 100 and the second wall 200 are distributed. Thus, during the process of adding water to the water injection chamber 500, the diversion wall 320 and the second wall 200 can divert water into the gap between the water retaining wall 310 and the second wall 200, thereby improving the convenience of adding water. At the same time, the water flowing into the water injection chamber 500 first flows along the second wall 200, preventing the water from flowing out of the water outlet 110 during the process of adding water to the water injection chamber 500. In addition, when water flows in the flow channel with gradually decreasing width, the water flow will be weakened, thereby reducing the impact of the water filling process on the cavity wall of the water filling chamber 500 and improving the structural stability of the water filling box. Of course, in other embodiments, the distance between the drainage wall 320 and the second wall 200 can also be kept constant, or the distance between the drainage wall 320 and the second wall 200 can be gradually increased in the direction of water filling toward the water filling chamber 500.

[0045] Specifically, in this embodiment, please refer to Figures 2 to 4 , the drainage wall 320 extends obliquely relative to the second wall 200, and is set at an acute angle to the water retaining wall 310. It can be understood that the angle between the drainage wall 320 and the water retaining wall 310 is an acute angle, then the second wall 200, adjacent to the position of the water inlet 400, still maintains a shape parallel to the first wall 100, and in the process of adding water to the water injection box, the water flow will first encounter the drainage wall 320, prompting the water flow to flow toward the second wall 200 along its extension direction, thereby ensuring that the path for the water flow to enter the water injection chamber 500 is clearer and more orderly. In addition, it is also possible to avoid making changes to the second wall 200, ensuring that after the water injection box is installed in the predetermined position, the second wall 200 and the shape of the ice maker and other equipment can be kept in a shape-matching setting, thereby ensuring the compactness of the equipment. Among them, in this embodiment, please refer to Figure 3 The drainage wall 320 is connected to the side of the water retaining wall 310 near the second wall 200. After being guided by the drainage wall 320, the water flows directly into the water injection chamber 500 along the drainage direction, specifically sliding along the second wall 200 without being disrupted by the water retaining wall 310. This prevents the water in the water injection chamber 500 from overflowing or spilling out of the water outlet 110 during the water filling process. Of course, in other embodiments, the drainage wall 320 can also be parallel to the first wall 100, and the portion of the second wall 200 corresponding to the drainage wall 320 extends outward in an inclined manner away from the drainage wall 320.

[0046] In one embodiment, please refer to Figures 2 to 4 The water retaining wall 310 is connected to the side of the second wall 200 near the water inlet 400, and has an angle α with the first wall 100, where α satisfies: 75°≤α≤115°. Taking the side of the water retaining wall 310 facing the water injection chamber 500 as a reference, the angle α between the first wall 100 and the water retaining wall 310 can be 90°, that is, the water retaining wall 310 is perpendicular to the first wall 100, or α is an obtuse angle less than or equal to 115°, or α is an acute angle greater than or equal to 75°. In this way, the water flow is buffered and dispersed after contacting the water retaining wall 310, thereby reducing the risk of water directly rushing towards the water outlet 110 or overflowing the water injection chamber 500 due to inertia. It is also possible to provide an adapted water retaining wall 310 according to water injection boxes of different specifications and water volumes, thereby improving the deformation resistance and durability of the water injection box while ensuring water retaining stability. Specifically, α is 80°, 90°, 100°, or 110°.

[0047] In one embodiment, please refer to Figures 2 to 4, define the distance between the water retaining part 300 and the second wall 200 as L1, and define the minimum distance between the first wall 100 and the second wall 200 as L2, and L1 and L2 satisfy: 0.1≤L1 / L2≤0.3. It should be noted that L2 represents the minimum thickness of the water injection cavity 500, which is usually the distance from the connection between the water retaining wall 310 and the first wall 100 to the second wall 200. L1 / L2 is limited to be greater than or equal to 0.1 and less than or equal to 0.3, ensuring that the protrusion height of the water retaining wall 310 from the first wall 100 to the second wall 200 can intercept the water flow from the water inlet 400. At the same time, during the process of adding water to the water injection box, it also prevents the water retaining wall 310 from forming too much resistance to the water adding process, thereby ensuring the convenience of water adding. Specifically, L1 / L2 can take values ​​of 0.15, 0.2, 0.25 or 0.3, etc. Of course, in other embodiments, L2 can be defined by taking the position where the water retaining wall 310 is connected to the first wall 100 as the starting point and the position of the second wall 200 relative to the water retaining wall 310 as the end point, and L1 is defined as the protrusion distance of the water retaining portion 300 from the first wall 100 toward the second wall 200.

[0048] In one embodiment, please refer to Figure 1 and Figure 2 A water level warning portion 210 is provided on the first wall 100 and / or the second wall 200, and the water outlet 110 and the water inlet 400 are respectively provided on opposite sides of the water level warning portion 210. It should be noted that the user can observe the water level in the water filling chamber 500 through the water level warning portion 210. At this time, the posture of the water filling box is that the water inlet 400 faces upward, and the thickness direction of the water filling chamber 500 is horizontal. The water level warning portion 210 can be set as a transparent part on the first wall 100 or the second wall 200, or it can be set as an electronic display screen, which identifies the water level through a sensor and displays it on the water level warning portion 210. Specifically, the water level warning portion 210 in this embodiment is used to provide the user with a maximum amount of water to add to the water filling box. Exceeding this amount may result in: water overflowing from the water outlet 110 during the water filling process; or excessive water in the water filling box, which may overfill the ice mold 602; or water overflowing from the water inlet 400 during the installation of the water filling box. Thus, by providing the water level warning portion 210, overflowing during use is avoided, allowing the user to precisely control the amount of water added, thereby improving user convenience. In this embodiment, the water level warning portion 210 is disposed on the second wall 200. After the water filling box is installed in the predetermined position, the water level warning portion 210 can be exposed outside the device for installation, making it easier for the user to observe the water level in the water filling box.

[0049] In one embodiment, please refer to Figures 2 to 5, the water outlet 110 is arranged adjacent to the water inlet 400. Referring to the above description of adding water to the water filling box, when adding water to the water filling box, the water inlet 400 is facing upward, and the water outlet 110 is arranged adjacent to the water inlet 400, so that water can be added to the water filling chamber 500 as much as possible, that is, the amount of water that can be stored in the water filling chamber 500 is increased. Without loss of generality, during the installation of the water filling box, it is necessary to push the water filling box horizontally. At this time, the water inlet 400 of the water filling box is at the front, and the water outlet 110 is arranged adjacent to the water inlet 400. During the installation of the water filling box, the water flowing out of the water outlet 110 can fall into the lower ice mold 602, preventing the water from spilling outside the ice maker, thereby improving the installation convenience of the water filling chamber 500. Of course, in other embodiments, a sealing plate can also be provided on the water outlet 110 . After the water filling box is installed to the predetermined position, the sealing plate can be pushed open by the protrusion on the device, and the water in the water filling chamber 500 can flow out from the water outlet 110 .

[0050] On the other hand, in one embodiment, please refer to Figure 2 and Figure 4 The water retaining portion 300 is arranged near the water outlet 110, which can increase the volume of the water injection chamber 500, thereby increasing the amount of water that the water injection box can accommodate. In addition, referring to the installation process of the water injection box, the water retaining portion 300 is arranged near the water outlet 110. In the process of pushing the water injection box horizontally, the water inlet 400 is arranged forward. Similarly, the water retaining portion 300 intercepts the water flow at a position near the water inlet 400, ensuring that the water outlet 110 can smoothly discharge water. At the same time, it is also beneficial to ensure that the center of the water injection box is in the middle, which facilitates pushing the water injection box to the predetermined position.

[0051] In one embodiment, please refer to Figure 2 、 Figure 4 and Figure 5 In the water injection chamber 500, the first wall 100 extends obliquely toward the water outlet 110, and the location of the water outlet 110 is the farthest point from the first wall 100 to the second wall 200. The first wall 100 extends obliquely toward the water outlet 110, which can guide the water flow to flow more smoothly toward the water outlet 110, reduce the turbulence and eddy currents of the water flow in the water injection chamber 500, and make the water flow more orderly and efficient. At the same time, because the water outlet 110 is located at the farthest point from the first wall 100 to the second wall 200, when the water flows along the first wall 100, it will gradually converge near the water outlet 110 and be discharged, which helps to shorten the drainage path and speed up the drainage speed, thereby improving the drainage efficiency. Similarly, the inclined first wall 100 can also reduce water retention within the water injection chamber 500. When the water is guided by the inclined wall, it is easier to flow along a predetermined path and be discharged, thus avoiding the formation of dead water or water accumulation areas within the water injection chamber 500, thereby ensuring the ice making quality of the ice maker. Of course, in other embodiments, the side of the first wall 100 facing the water injection chamber 500 can also be set flat.

[0052] Further, in this embodiment, please refer to Figure 2 、 Figure 4 and Figure 5 The first wall 100 is recessed to form two symmetrically arranged water outlet grooves 120. Each water outlet groove 120 is provided with a water outlet 110. The symmetry axes of the two water outlet grooves 120 are parallel to the opening direction of the water inlet 400. Without loss of generality, taking the water filling box installed in the ice maker as an example, the water filling box discharges water respectively through two parallel and symmetrically arranged water outlet grooves 120. Correspondingly, the ice mold 602 at the bottom of the water filling box can also have parallel and symmetrically arranged ice trays. In this way, by providing two symmetrical water outlet grooves 120, the water outlet efficiency of the water filling box is improved, thereby improving the ice making efficiency. In addition, the two water outlets 110 can reduce the impact and turbulence of the water flow in the water filling chamber 500, making the water flow more stable and uniform. At the same time, the two water outlet grooves 120 arranged in opposition can also disperse the water flow and balance the pressure, which helps to reduce the noise and vibration generated by the water flow during the discharge process. Of course, in other embodiments, the side of the first wall 100 facing the water injection cavity 500 may be recessed to form a water outlet groove 120 , and water may be discharged through the water outlet groove 120 and the water outlet 110 .

[0053] For details, please refer to Figure 2 and Figure 4 In the present embodiment, for each water outlet trough 120, combined with the arrangement of the water outlet 110 adjacent to the water retaining portion 300, it can be understood that the deepest part of the bottom of the water outlet trough 120 (i.e., the position of the water outlet 110) is also arranged adjacent to the water retaining portion 300. In this way, the side wall of the water outlet trough 120 adjacent to the water retaining portion 300 also extends toward the second side wall, and is even perpendicular to the extension direction of the second side wall, thereby forming a certain interception effect on the flow of water toward the water outlet 110, thereby improving the effect of preventing water from overflowing in the water injection chamber 500. Similarly, the side of the water retaining portion 300 connected to the first wall body 100 is also adjacent to the side wall of the water outlet trough 120, showing that there is a certain distance between the side wall of the trough 120 and the diameter of the water retaining wall 310, and the side wall within this distance range extends at an angle so that the water retaining wall 310 and the trough wall of the water outlet trough 120 are smoothly connected through the side wall. In this way, when the water flow in the water injection chamber 500 is intercepted and overflows from the water inlet 400, the side wall of the water outlet trough 120 and the water retaining wall 310 can work together and prevent the water flow from being stirred up at the connection between the two, thereby improving the anti-overflow effect.

[0054] The present invention also provides an ice maker, comprising a body and a water filling box. The specific structure of the water filling box is similar to that of the above embodiments. Since the present ice maker adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The water filling box is mounted on the body.

[0055] In one embodiment, please refer to Figure 6 The body includes a supporting shell 601, an ice mold 602 and a collection box 603. The water injection box is arranged on the upper part of the supporting shell 601. The ice mold 602 is movably arranged at the lower part of the water injection box and is opposite to the water outlet 110. The collection box 603 is arranged on the supporting shell 601 and is located below the ice mold 602. Without loss of generality, the water filling box is detachably mounted on the support shell 601. After the user adds an appropriate amount of water to the water filling box, the water filling box is mounted in a predetermined position on the support shell 601. The water in the water filling box then flows downward from the water outlet 110 and falls onto the lower ice mold 602. After the ice mold 602 freezes and forms ice cubes, the ice cubes on the ice mold 602 are rotated or pushed to fall into the lower collection box 603. For the rotation method, the ice mold 602 has an ice dispensing knob 605 exposed outside the support shell 601. By rotating the ice dispensing knob 605, the ice mold 602 can be flipped and the ice cubes fall into the collection box 603. The user then removes the collection box 603 from the support shell 601 and removes the ice cubes. The collection box 603 may be provided with an ice scraper 604, which the user uses to remove the ice cubes according to the desired amount. In this way, the water injection and ice removal processes of ice making are completed through the action of gravity, thereby improving the convenience of using the ice maker.

[0056] The present invention also provides a refrigerator, which includes an ice maker. The specific structure of the ice maker refers to the above embodiments. Since the present refrigerator adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
