Description

Technical Field

[0001] This utility model relates to the technical field of water purifiers, and in particular to an ice-making module and a water purifier. Background Technology

[0002] An ice maker is a refrigeration machine that produces ice by cooling water through an evaporator with a refrigerant supplied by a refrigeration system. In other words, it uses a refrigeration system, with water as the carrier, to produce ice when the water is powered on and passes through a certain device.

[0003] A water purifier combines an ice maker and a water dispenser, enabling it to make ice. However, the ice-making module in existing water purifiers takes up a lot of space, resulting in a larger overall size. Utility Model Content

[0004] The main purpose of this invention is to propose an ice-making module and a water purifier, which aims to reduce the size of the ice-making module.

[0005] To achieve the above objectives, the ice-making module proposed in this utility model includes:

[0006] An ice storage box, wherein the ice storage box is provided with an ice outlet, the ice outlet being located at the front of the ice-making module;

[0007] An ice maker is located above the ice storage box, and the axial direction of the ice maker is consistent with the front-back direction of the ice making module.

[0008] An evaporator located within the cavity of the ice maker;

[0009] An ice dispensing assembly includes an ice dispensing motor and an ice dispensing screw. The ice dispensing screw is connected to the ice dispensing motor to dispense ice blocks from the ice storage box through the ice outlet. The ice dispensing screw extends along the front-back direction of the ice-making module.

[0010] In one embodiment, the ice-discharging screw is inclined upwards along the direction close to the ice outlet.

[0011] In one embodiment, the length of the ice-discharging screw in the front-to-back direction of the ice-making module is L1, and the length of the evaporator in the front-to-back direction of the ice-making module is L2, where 1.2L2≤L1≤1.7L2.

[0012] In one embodiment, the shortest distance between the ice-making box and the outer peripheral wall of the ice-discharging screw in the horizontal direction of the ice-making module is s1, and the radius of the ice-discharging screw is r, where s1 < r.

[0013] In one embodiment, the ice storage box includes a first cavity and a second cavity, the second cavity being located below the first cavity, and the cavity wall of the first cavity being inclined downward toward the first cavity so that the ice in the second cavity flows into the first cavity, and the ice dispensing screw is located in the first cavity.

[0014] In one embodiment, the maximum distance between the cavity wall of the first cavity and the outer peripheral surface of the ice-discharging screw is s2, and the radius of the ice-discharging screw is r, where s2 ≤ 2 / 3r.

[0015] In one embodiment, the ice-making module further includes a transfer assembly, which includes a transfer motor, an ice shovel box, and an ice shovel plate. The ice shovel box is located between the ice-making box and the ice storage box. The transfer motor is driven to the ice-making box to rotate the ice-making box, so as to drop the ice blocks in the ice-making box into the ice shovel box. The ice shovel plate is installed on the ice-making box. When the transfer motor drives the ice-making box to rotate, the ice shovel plate shovels the ice blocks in the ice shovel box into the ice storage box.

[0016] In one embodiment, the opening of the ice scoop box is larger than the opening of the ice maker box, and the ice maker box is at least partially located inside the ice scoop box.

[0017] In one embodiment, the sidewall of the ice scooping box facing the ice dispensing screw is arc-shaped, and the projections of the ice scooping box and the ice dispensing screw in the vertical direction of the ice-making module at least partially overlap. When the transfer motor drives the ice-making box to rotate, the ice scooping plate scoops the ice from the ice scooping box into the ice storage box and falls directly above the ice dispensing screw.

[0018] In one embodiment, the shortest distance between the outer peripheral wall of the ice-discharging screw and the ice-scooping box is s3, and the radius of the ice-discharging screw is r, where s3 ≤ 1 / 2r.

[0019] This utility model also proposes a water purifier, including the ice-making module described above.

[0020] In this invention, the water in the ice-making box is cooled by an evaporator to produce ice. An ice-discharging motor then drives an ice-discharging screw, which in turn discharges the ice from the ice storage box through the ice outlet. The ice-making box is positioned above the ice storage box, meaning they are stacked. Compared to existing technologies where the ice-making and ice storage boxes are spaced apart in the front-back direction of the ice-making module, this stacked arrangement reduces the front-back and left-right dimensions of the ice-making module. Furthermore, the axial direction of the ice-making box is aligned with the front-back direction of the ice-making module, and the ice-discharging screw also extends along the front-back direction of the ice-making module. This means the extension direction of the ice-discharging screw is aligned with the extension direction of the ice-making section of the evaporator. Compared to existing technologies where the ice-discharging screw and evaporator are intersected, this aligning the extension direction of the ice-discharging screw with the axial direction of the ice-making box further reduces the left-right dimensions of the ice-making module.

[0035] An ice maker is a refrigeration machine that uses a refrigerant supplied by a refrigeration system to cool water through an evaporator to produce ice. In other words, it uses a refrigeration system, with water as the carrier, to produce ice when electricity is applied. A water purifier combines an ice maker and a water dispenser, thus enabling it to make ice. However, the ice-making module in existing water purifiers occupies a significant amount of space, resulting in a larger overall size for the water purifier.

[0036] Reference Figure 1 and Figure 2 This utility model proposes an ice-making module, comprising:

[0037] An ice storage box 10 is provided with an ice outlet 13, which is located at the front of the ice-making module.

[0038] An ice maker 20 is located above the ice storage box 10, and the axial direction of the ice maker 20 is consistent with the front-back direction of the ice making module.

[0039] Evaporator 30, which is located inside the cavity of the ice-making box 20;

[0040] An ice dispensing assembly includes an ice dispensing motor 41 and an ice dispensing screw 42. The ice dispensing screw 42 is connected to the ice dispensing motor 41 to dispense ice blocks from the ice storage box 10 through the ice outlet 13. The ice dispensing screw 42 extends along the front-back direction of the ice making module.

[0041] In this invention, the water in the ice-making box 20 is cooled by the evaporator 30 to produce ice. Then, the ice-discharging motor 41 drives the ice-discharging screw 42 to rotate, causing the screw to discharge the ice from the ice storage box 10 through the ice outlet 13. The ice-making box 20 is located above the ice storage box 10, meaning the ice-making box 20 and the ice storage box 10 are stacked. Compared to the prior art where the ice-making box 20 and the ice storage box 10 are spaced apart in the front-back direction of the ice-making module, this invention's solution... The stacked arrangement of 10 reduces the size of the ice-making module in both the front-back and left-right directions. Furthermore, the axial direction of the ice-making box 20 is consistent with the front-back direction of the ice-making module, and the ice-discharging screw 42 also extends along the front-back direction of the ice-making module. That is, the extension direction of the ice-discharging screw 42 is consistent with the extension direction of the ice-making part of the evaporator 30. Compared with the existing technical solution in which the ice-discharging screw 42 and the evaporator 30 are arranged in an intersecting manner, the technical solution of this application makes the extension direction of the ice-discharging screw 42 consistent with the axial direction of the ice-making box 20, thereby reducing the size of the ice-making module in the left-right direction.

[0042] When the ice in the ice storage box is idle, some of the ice may melt, and the melted water may stick to adjacent ice blocks, causing multiple ice blocks to clump together. This could prevent the ice dispensing screw from discharging the ice. Therefore, in this embodiment, the ice dispensing screw 42 is inclined upwards along the direction close to the ice outlet 13. By inclining the ice dispensing screw 42, the projection of the ice dispensing screw 42 in the front-back direction of the ice-making module is reduced, thus reducing the size of the ice dispensing module in the front-back direction. By also inclining the bottom of the ice storage box 10 corresponding to the ice dispensing screw 42, the volume of the ice storage box 10 is increased. At the same time, it allows the ice blocks in the ice storage box 10 to gather at the bottom of the ice dispensing screw 42 and then be transported to the ice outlet 13. At the same time, the ice blocks in the ice storage box 10 are all gathered at the bottom of the ice dispensing screw 42, so that all the ice blocks can be gathered together. This allows the ice dispensing screw 42 to rotate and cause the ice blocks in the ice storage box 10 to tumble together. This makes it less likely for the ice blocks in the ice storage box 10 to melt and re-stick together, thereby reducing the possibility of the ice blocks re-sticking together after melting and improving the ice making efficiency of the ice making module.

[0043] Reference Figure 2 Furthermore, the length of the ice-discharging screw 42 in the front-back direction of the ice-making module is L1, and the length of the evaporator 30 in the front-back direction of the ice-making module is L2, where 1.2L2≤L1≤1.7L2. It should be noted that L1 is the projected length of the ice-discharging screw 42 in the front-back direction of the ice-making module, not the length along its own axis. If L1 > 1.7L2, it indicates that the projected length of the ice-discharging screw 42 in the front-back direction of the ice-making module is too large, meaning the tilt angle of the ice-discharging screw 42 is small, resulting in an excessively large size of the ice-making module in the front-back direction, which is detrimental to miniaturization. If L1 < 1.2L2, it indicates that the projected length of the ice-discharging screw 42 in the front-back direction of the ice-making module is too small, meaning the tilt angle of the ice-discharging screw 42 is large, resulting in an excessively large size of the ice-making module in the vertical direction, which is also detrimental to miniaturization. Therefore, by limiting 1.2L2≤L1≤1.7L2 within a reasonable range, the dimensions of the ice-making module in both the vertical and horizontal directions are balanced, which is beneficial for the miniaturization of the ice-making module. At the same time, the relatively large range of 1.2L2 to 1.7L2 facilitates the installation of the ice-dispensing screw 42, reduces the tilting error of the ice-dispensing screw 42, and thus reduces the manufacturing and installation errors of the ice-making module, thereby reducing the production cost of the ice-making module.

[0044] Reference Figure 3Preferably, the shortest distance between the ice-making box 20 and the outer peripheral wall of the ice-dispensing screw 42 in the horizontal direction of the ice-making module is s1, and the radius of the ice-dispensing screw 42 is r, where s1 < r. Understandably, if s1 ≥ r, it indicates that the horizontal distance between the ice-making box 20 and the ice-dispensing screw 42 is too large, resulting in an excessively large lateral dimension of the ice-making module, which is detrimental to miniaturization. Therefore, by setting s1 < r, the horizontal distance between the ice-dispensing screw 42 and the side wall of the ice-making box 20 is reasonably set, thereby reducing the lateral dimension of the ice-making module, making the internal structure of the ice-making module more compact, and thus facilitating miniaturization.

[0045] Reference Figure 4 and Figure 5 In one embodiment, the ice storage box 10 includes a first cavity 11 and a second cavity 12. The second cavity 12 is located below the first cavity 11, and the cavity wall of the first cavity 11 is inclined downward toward the first cavity 11 so that the ice in the second cavity 12 flows into the first cavity 11. The ice dispensing screw 42 is located inside the first cavity 11. That is, the ice dispensing screw 42 is located at the lowest position of the ice storage box 10, so that all the ice in the ice storage box 10 can be collected at the ice dispensing screw 42. At the same time, when the ice dispensing screw 42 rotates, it can not only transport the ice in the ice dispensing screw 42 to the ice outlet 13, but also move the remaining ice in the ice storage box 10 together, thereby preventing the ice in the ice storage box 10 from sticking together, thus improving the ice making effect and ice transportation efficiency of the ice making module. The second cavity 12 is used to contain ice blocks that fall from the ice scoop box 52 into the first cavity 11 and then overflow from the first cavity 11, thereby increasing the volume of the ice storage box 10.

[0046] Specifically, the maximum distance between the cavity wall of the first cavity 11 and the outer circumference of the ice-discharging screw 42 is s2, and the radius of the ice-discharging screw 42 is r, where s2 ≤ 2 / 3r. Understandably, if s2 > 2 / 3r, it indicates that the gap between the ice-discharging screw 42 and the cavity wall of the first cavity 11 is too large, causing ice blocks to get stuck between them. This makes it easy for the ice-discharging screw 42 to break the ice blocks during rotation, leading to ice block breakage and making transportation impossible. Therefore, setting s2 ≤ 2 / 3r ensures that the ice blocks only rest on the cavity wall of the ice-discharging screw 42 and the first cavity 11. This prevents the ice blocks from sticking together again during rotation, thus improving the integrity of the ice blocks and enhancing the ice-making effect of the ice-making module.

[0047] Furthermore, the bottom wall of the first cavity 11 is spaced apart from the ice-discharging screw 42. On the one hand, s2≤2 / 3r prevents ice from getting stuck between the ice-discharging screw 42 and the first cavity 11. On the other hand, the ice-discharging screw 42 separates a space inside the ice storage box 10, allowing the water from the melting ice in the ice storage box 10 to flow into this space. This prevents excessive water in the ice storage box 10 from accelerating the melting speed of the ice in the ice storage box 10, and also reduces the chance of the ice in the ice storage box 10 re-adheding after melting. This improves the ice-making effect and efficiency of the ice-making module.

[0048] In one embodiment, the ice-making module further includes a transfer assembly, which includes a transfer motor 51, an ice scoop box 52, and an ice scooping plate 53. The ice scoop box 52 is located between the ice-making box 20 and the ice storage box 10. The transfer motor 51 is connected to the ice-making box 20 to drive the ice-making box 20 to rotate, so as to drop the ice blocks in the ice-making box 20 into the ice scoop box 52. The ice scooping plate 53 is installed on the ice-making box 20. When the transfer motor 51 drives the ice-making box 20 to rotate, the ice scooping plate 53 scoops the ice blocks in the ice scoop box 52 into the ice storage box 10.

[0049] Understandably, the ice maker 20 has an ice-making state and an ice-falling state. When the ice maker 20 is in the ice-making state, the opening of the ice maker 20 faces upward. At this time, the evaporator 30 cools the water in the ice maker 20 to make the corresponding ice cubes. Then, the transfer motor 51 drives the ice maker 20 to rotate so that the ice maker 20 switches from the ice-making state to the ice-falling state. The rotation angle of the ice maker 20 can be set according to actual needs. It is only necessary to let all the ice cubes in the ice maker 20 fall into the ice-shoveling box 52. When the ice maker 20 is in the ice-falling state, the opening of the ice maker 20 can be vertically downward or tilted downward so that the ice cubes in the ice maker 20 fall into the ice-shoveling box 52. Then, the transfer motor 51 changes the rotation direction so that the ice maker 20 rotates back, thereby switching the ice maker 20 from the ice-falling state to the ice-making state. At this time, the ice-shoveling plate 53 on the ice maker 20 shovels all the ice cubes in the ice-shoveling box 52 into the ice storage box 10. The ice scoop box 52 serves to transfer the ice, preventing the ice from breaking when it falls due to a large drop between the ice maker box 20 and the ice storage box 10. At the same time, there may still be some unfrozen water in the ice maker box 20. The ice scoop box 52 can prevent too much water from flowing into the ice storage box 10.

[0050] Specifically, the opening of the ice scooping box 52 is larger than the opening of the ice making box 20, and the ice making box 20 is at least partially located inside the ice scooping box 52. Understandably, since the ice scoop box 52 mainly serves as a transfer station for ice blocks, when the ice scoop box 52 contains ice blocks, the ice maker box 20 has already flipped upwards. That is, at this time, the ice scoop box 52 can be filled with ice blocks, and the ice blocks may even protrude from the upper surface of the ice scoop box 52. Therefore, the ice maker box 20 does not occupy the space of the ice scoop box 52 at this time. When the ice maker box 20 rotates back, the ice scoop plate 53 has already transferred all the ice blocks in the ice scoop box 52 to the ice storage box 10. That is, when the ice maker box 20 returns to the ice-making state, there are no large ice blocks in the ice scoop box 52. The ice fragments that the ice scoop plate 53 did not remove are not within the scope of consideration in this application. Therefore, the volume of the ice scoop box 52 does not need to be set too large. Therefore, placing the ice maker box 20 at least partially inside the ice maker box 52 reduces the space occupied by the ice maker box 20 and the ice scoop box 52, making the ice-making module structure more compact, which is conducive to the miniaturization of the ice-making module. The opening of the ice scoop box 52 is larger than the opening of the ice maker box 20 to prevent the ice cubes inside the ice maker box 20 from falling directly into the ice storage box 10 during the flipping process, which would cause the ice cubes to break. This reduces the ice breakage rate and improves the ice-making effect of the ice-making module.

[0051] When the ice-making module makes ice, only one ice block slides out of the ice outlet 13 at a time. If the ice block breaks, it becomes difficult to control the amount of ice dispensed, as it is impossible to control whether the next ice block sliding out of the outlet 13 is intact and what the integrity rate is. In one embodiment, the ice shovel box 52 is arc-shaped towards the side wall of the ice dispensing screw 42, and the projections of the ice shovel box 52 and the ice dispensing screw 42 in the vertical direction of the ice-making module at least partially overlap. When the transfer motor 51 drives the ice-making box 20 to rotate, the ice shovel plate 53 shovels the ice block from the ice shovel box 52 into the ice storage box 10, and it falls directly above the ice dispensing screw 42. That is, the ice dispensing screw 42 is at least partially located below the ice shovel box 52, thereby determining the dimension between the ice screw 42 and the ice shovel box 52 in the horizontal direction of the ice-making module, making the structure of the ice-making module more compact, which is beneficial for the miniaturization of the ice-making module. This also ensures that the ice blocks from the ice shovel 52 falling into the ice storage box 10 first land directly on the ice dispensing screw 42, thereby reducing the time loss of the ice blocks during the transfer process and improving the ice dispensing efficiency of the ice dispensing screw 42. At the same time, if the ice blocks fall directly from the ice shovel 52 into the ice storage box 10, the height difference is large, making the ice blocks easy to break. Therefore, letting the ice blocks fall directly onto the ice dispensing screw 42 also reduces the distance the ice blocks fall from the ice shovel 52, thereby reducing the breakage rate of the ice blocks and improving the accuracy of the ice dispensing amount.

[0052] Reference Figure 3Specifically, the shortest distance between the outer peripheral wall of the ice-dispensing screw 42 and the ice-scooping box 52 is s3, and the radius of the ice-dispensing screw 42 is r, where s3 ≤ 1 / 2r. By further limiting the distance between the outer peripheral wall of the ice-dispensing screw 42 and the ice-scooping box 52, the ice-making module structure becomes more compact, thereby further reducing the size of the ice-making module in the left-right direction, which is beneficial to the miniaturization of the ice-making module.
