[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] 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.

[0044] Please see Figures 1 to 6 One embodiment of this application provides an ice maker including a body 11, a base plate 12, and an ice-making circulation assembly 20. The base plate 12 is fixed to the bottom of the body 11 and encloses the body 11 to form an installation space (not shown in the figure), and the ice-making circulation assembly 20 is housed within the installation space. The body 11 has an inner cavity 10b, which is divided into an ice-making zone (not shown in the figure), an ice storage zone (not shown in the figure), and a water storage zone (not shown in the figure) according to different height ranges.

[0045] In addition, the ice maker also includes an ice-making and ice-removing mechanism 30, an ice storage basket 40, a water supply assembly (not shown in the figure), and a controller (not shown in the figure).

[0046] The ice-making and ice-shoveling mechanism 30 is located within the ice-making area and configured to flip towards the ice storage area to scoop out the produced ice blocks. Exemplarily, the ice-making and ice-shoveling mechanism 30 includes a water container and an ice-shoveling plate. The support shaft of the water container is connected in sequence to a motor located outside the ice storage area via a drive shaft, a connecting rod, and an eccentric component. The motor is electrically or communicatively connected to a controller. The ice-shoveling plate is hinged to the side of the water container facing the opening.

[0047] The ice storage basket 40 is located in the ice storage area and is connected to the body 11.

[0048] The water supply components include a circulation pump (not shown in the figure) and circulation piping (not shown in the figure). The circulation pump is housed within the installation space and is electrically or communicatively connected to the controller. One end of the circulation pump is connected to the water storage area, and the other end is connected to the water collection box via the circulation piping.

[0049] The ice-making circulation assembly 20 includes a refrigeration component 210. (Please refer to...) Figure 5 or Figure 6 See also Figure 4 The cooling component 210 includes a main body 2101 and a support portion 2102 extending outward from the bottom of the main body 2101. The support portion 2102 is mounted and fixed to the base plate 12, leaving the main body 2101 suspended. This suspended configuration of the cooling component 210 promotes airflow and prevents overheating due to poor heat dissipation. Exemplarily, both the cooling component 210 and the base plate 12 are made of metal. The support portion 2102 is mounted and fixed to the base plate 12 using screws and insulating washers.

[0050] In addition, the refrigeration cycle assembly also includes a condenser (not shown), a dryer filter (not shown), an evaporator (not shown), and a return gas connection pipe (not shown). The condenser is housed within the installation space and is fixedly mounted on the base plate 12. The evaporator is located above the water tank, and multiple ice-making tubes of the evaporator are inserted side-by-side into the water tank. The evaporator is connected to the condenser through the dryer filter and also connected to the main body 2101 through the return gas connection pipe.

[0051] In addition, such as Figure 4 or Figure 5 As shown, the refrigeration cycle assembly also includes a cooling fan 220. The cooling fan 220 is housed within the installation space and attached to one side of the condenser. The cooling fan 220 is electrically or communicatively connected to the controller.

[0052] The controller is configured to operate the ice maker based on user input to the ice maker (such as its user interface), input from various sensors located within the ice maker, and / or other suitable input.

[0053] To facilitate the reader's understanding of the ice-making principle of the ice maker involved in this application, the ice-making and ice-removal process of the ice maker is described below, using the compressor as an example in the ice-making circulation assembly 20. Specifically, as follows:

[0054] First, the circulation pump receives a command from the controller and turns on, continuously pumping the ice-making water in the ice storage area into the water container until it overflows.

[0055] Simultaneously, or after the water tank overflows, the compressor receives a command from the controller to activate. Refrigerant is discharged from the compressor's discharge port and enters the condenser, where it is condensed. The refrigerant then enters the dryer filter for drying. The dried refrigerant then enters the evaporator, cooling it. Meanwhile, the multiple ice-making tubes in the evaporator cool the water in the water tank. Over time and with the progress of the refrigeration cycle, the water in the water tank gradually cools and eventually freezes into ice. During the condensation process, the cooling fan adjusts its speed according to the condenser's temperature changes, accelerating airflow.

[0056] In the above refrigeration cycle, the refrigerant flowing through the evaporator returns to the compressor through the corresponding pipeline. After ice making is complete, the refrigerant stops working in the evaporator.

[0057] Secondly, the motor receives the controller's command and is activated. The motor drives the transmission shaft, connecting rod, and eccentric component to rotate the water box toward the ice storage area. The ice scraper plate descends as the water box rotates, and the water in the water box is poured into the water storage area for subsequent circulation pump use. The ice blocks are slightly heated and melted so that they fall onto the ice scraper plate under gravity.

[0058] Finally, as the motor reverses, the water box flips back to its original position, the ice scraper lifts up to scrape out the ice, and the ice rolls down and collects in the ice storage basket.

[0059] It is understood that the embodiments of this application do not specifically limit the shape of the ice-making component, as long as it can meet the condition that the operating temperature is lower than the dew point temperature of the surrounding air to produce liquid. For example, the ice-making component can also be a condenser, an evaporator, or the inner liner assembly of the machine body, etc.

[0060] For base plate 12, please refer to Figure 6 and Figure 5 In some embodiments, the base plate 12 is provided with a first sink 121, and the support portion 2102 of the refrigeration component 210 is fixedly installed on the bottom wall of the first sink 121. The first sink 121 is located below the ice-making circulation assembly 20 and collects the liquid generated during the operation of the ice-making circulation assembly 20. It should be noted that the liquid generated during the operation of the ice-making circulation assembly 20 mentioned here is the condensate generated when the outer wall of each component of the ice-making circulation assembly 20 is lower than the dew point temperature of the surrounding air during ice making. However, the flow direction of this condensate is not controllable, and the condensate does not easily flow to the designated drainage location. For this reason, the first sink 121 is provided on the base plate 12, wherein the height of the bottom wall of the first sink 121 is lower than the height of the base plate 12. This structural arrangement allows the first sink 121 to collect condensate, thereby improving the situation of damage to electrical components or leakage of the ice maker caused by condensate accumulation.

[0061] Furthermore, the orthographic projection of the ice-making circulation assembly 20 on the horizontal plane at least partially overlaps with the orthographic projection of the first trough 121 on the horizontal plane. For example, at least a portion of the structure of the main body 2101 coincides with the orthographic projection of the first trough 121 on the horizontal plane. Since the locations where condensate is generated by the ice-making circulation assembly 20 are widely distributed, by increasing the overlap area of ​​the first trough 121 relative to the refrigeration circulation assembly, the water collection area of ​​the first trough 121 is increased, further reducing the possibility of condensate flowing to other electrically charged components.

[0062] Furthermore, please combine Figure 6 See also Figure 4A portion of the bottom wall of the first trough 121 is recessed downwards to form a second trough 123. The second trough 123 can collect condensate collected from the first trough 121, preventing the condensate from overflowing and flowing to other live components. Furthermore, the second trough 123 is located below the main body 2101, and the orthographic projection of the main body 2101 on the horizontal plane at least partially overlaps with the orthographic projection of the second trough 123 on the horizontal plane. For example, at least a portion of the structure of the main body 2101 coincides with the orthographic projection of the second trough 123 on the horizontal plane. Thus, the second trough 123 can be positioned below the main body 2101, where condensate is prone to form, for better condensate collection.

[0063] like Figure 4 As shown, in some embodiments, a first transition slope 120 is provided between the base plate 12 and the first sink 121, and a second transition slope 122 is provided between the first sink 121 and the second sink 123. The slopes of both the second transition slope 122 and the first transition slope 120 satisfy a range of 15° to 60°. For example, the slopes of the second transition slope 122 and the first transition slope 120 can specifically be 15°, 18°, 20°, 25°, 32°, 36°, 38°, 40°, 45°, 48°, 52°, 56°, 58°, 60°, or any two of the aforementioned values. In this technical solution, arranging the transition slopes at 15° to 60° helps to disperse stress and ensure the structural stability of the transition section.

[0064] In some embodiments, the ratio of the projected area of ​​the second sink 123 on the horizontal plane to the projected area of ​​the first sink 121 on the horizontal plane is between 1 / 4 and 1 / 2. For example, the ratio can specifically be 1 / 4, 1 / 3, 2 / 5, 3 / 7, 4 / 9, 5 / 12, 1 / 2, or any two of the aforementioned values. In this technical solution, the ratio is limited to this range, which is suitable for both the area covered by the first sink 121 where condensate is generated in the refrigeration cycle assembly and the area covered by the second sink 123 where condensate is generated on the main body 2101.

[0065] like Figure 4 As shown, in some embodiments, the depth of the first settling tank 121 is between 2.5 mm and 6 mm. Specifically, the depth of the first settling tank 121 can be 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.6 mm, 3.8 mm, 4 mm, 4.5 mm, 5 mm, 5.4 mm, 6 mm, or a range between any two of the aforementioned values.

[0066] The depth of the second settling tank 123 is between 5mm and 10mm. Specifically, the depth of the second settling tank 123 can be 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm or any two of the aforementioned values.

[0067] In this technical solution, the second settling tank 123 has a deeper depth range than the first settling tank 121. On the one hand, the second settling tank 123 forms a larger water holding volume, which can further prevent the condensate in the first settling tank 121 from overflowing and flowing to other live parts. On the other hand, it also increases the distance between the bottom plate 12 and the bottom of the main body 2101, reducing the collision risk of the ice maker caused by falling vibration.

[0068] For body 11, such as Figure 1 and Figure 2 As shown, in some embodiments, the body 11 includes multiple protective shells 110 and an inner liner assembly 111. The inner liner assembly 111 includes a support frame and an inner liner. The cross-sectional shape of the inner liner is approximately inverted 7-shape, defining the aforementioned inner cavity 10b. An opening (not shown) is also provided on the inner liner to connect the inner cavity 10b with the external environment. The ice-making area is located at the top rear side of the inner liner, the ice-storing area is located in the middle of the inner liner and directly communicates with the aforementioned opening, and the water-storing area is located at the bottom of the inner liner. The shape of the support frame is adapted to the shape of the inner liner, and the support frame is fitted over the inner liner, with a portion of the inner liner overlapping the support frame. Multiple protective shells 110 correspond to different sides of the support frame and, together with the base plate 12, enclose the inner liner assembly 111 within it. The base plate 12, a portion of the support frame, and the multiple protective shells 110 together form the aforementioned installation space.

[0069] Continue as Figure 1 or Figure 2 As shown, in some embodiments, the body 11 further includes a door assembly 112. A plurality of protective shells 110 include a fourth protective shell 1106, which is correspondingly mounted and fixed to the front side of the inner liner assembly 111 and exposes an opening. The door assembly 112 is rotatably connected to the fourth protective shell 1106 to open or close the opening.

[0070] Continue as Figure 1 As shown, the aforementioned ice storage basket 40 is detachably connected to one side of the door assembly 112 and reciprocates through the opening as the door assembly 112 moves to accommodate or detach from the ice-making area. In specific implementation, when the door assembly 112 is flipped to open the opening, the ice storage basket 40 is exposed to the external environment through the opening, allowing the user to easily remove the ice blocks; when the door assembly 112 is flipped to close the opening, the ice storage basket 40 returns to its original position within the ice storage area through the opening.

[0071] Please combine Figure 2See also Figure 3 or Figure 4 In some embodiments, the plurality of protective shells 110 include a first protective shell 1101 and a second protective shell 1103 disposed opposite to each other. One of the first protective shell 1101 and the second protective shell 1103 is disposed on the left side of the inner liner assembly 111, and the other is disposed on the right side of the inner liner assembly 111. The first protective shell 1101 has a plurality of first grille holes 110a. The second protective shell 1103 has a plurality of second grille holes 110b. The plurality of second grille holes 110b, the first settling tank 121, and the plurality of first grille holes 110a are connected to form an air passage. In this technical solution, the condensate in the first settling tank 121 can evaporate more quickly through the air passage, thereby preventing the accumulation of condensate and keeping the ice maker dry and clean. Furthermore, since the condensate is evaporated, the need for regular drainage is reduced, thereby reducing maintenance frequency and costs.

[0072] like Figure 4 As shown, in some embodiments, the cooling fan 220 is positioned closer to the second protective housing 1103 than the first protective housing 1101, and the cooling fan 220 is positioned opposite to the second protective housing 1103. Therefore, the cooling fan 220 can further accelerate the evaporation of condensate in the first settling tank 121, enabling the ice maker to operate normally in environments with higher condensation levels.

[0073] For ease of description, the following example will be provided with the first protective shell 1101 positioned on the right side of the inner liner assembly 111 and the second protective shell 1103 positioned on the left side of the inner liner assembly 111. The airflow pattern near the first settling tank 121 is as follows: outside air first enters the installation space through the first grille hole 110a, and under the suction of the cooling fan 220, it accelerates through the gap between the main body 2101 and the first settling tank 121 before being discharged through the second grille hole 110b. At the same time, the flowing airflow accelerates the reduction of the surface temperature of the condensate, thereby accelerating the evaporation of water.

[0074] Furthermore, such as Figure 3 As shown, the first protective shell 1101 is provided with a first partition wall 1102 extending into the installation space. The first partition wall 1102 divides the plurality of first grille holes 110a into a plurality of first upper grille holes and a plurality of first lower grille holes. The first sink 121, the plurality of first lower grille holes, and the plurality of second grille holes 110b are connected to form the aforementioned air passage. In this technical solution, the presence of the first partition wall 1102 can divide the air flowing into the first grille into two airflows, upper and lower. The lower airflow flows through the gap between the main body 2101 and the first sink 121 and is then carried away by the cooling fan 220, thereby ensuring that the area near the first sink 121 is always in a state of accelerated evaporation.

[0075] Furthermore, such as Figure 2 or Figure 3 As shown, the plurality of protective shells 110 also includes a rear protective shell 1104. The rear protective shell 1104 is disposed between the first protective shell 1101 and the second protective shell 1103. The rear protective shell 1104 has a plurality of third grille holes 110c. Some of the third grille holes 110c are connected to the installation space, while others are not connected to the air passage. For example, the rear protective shell 1104 is disposed on the rear side of the inner liner assembly 111. The rear protective shell 1104 has a second partition wall 1105 extending into the installation space. The second partition wall 1105 divides the plurality of third grille holes 110c into a plurality of second upper grille holes and a plurality of second lower grille holes. The plurality of second upper grille holes are connected to the installation space, while the plurality of second lower grille holes are not connected to the air passage. This can prevent the airflow entering from the second lower grille holes from interfering with the flow of the lower airflow, thereby ensuring that the lower airflow passes smoothly through the bottom wall of the first settling tank 121 to accelerate the evaporation of condensate.

[0076] In summary, the ice maker of this application has a first settling tank 121 on the base plate 12, wherein the bottom wall of the first settling tank 121 is lower than the height of the base plate 12. This structural design allows the first settling tank 121 to collect condensate, thereby improving the situation where condensate accumulation causes damage to electrical components or leakage of the ice maker. Furthermore, multiple second grille holes 110b, the first settling tank 121, and multiple first grille holes 110a are connected to form an air passage. The condensate in the first settling tank 121 can evaporate more quickly through the air passage, thereby preventing condensate accumulation and keeping the ice maker dry and clean. In addition, because the condensate is evaporated, the need for regular drainage is reduced, thus lowering maintenance frequency and costs.
