[0041] 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.

[0042] 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.

[0043] Please see Figures 1 to 10 One embodiment of this application provides an ice maker including an ice maker body 10 and an electronic control board assembly 20. The electronic control board assembly 20 is disposed within the ice maker body 10 and electrically connected to the ice maker body 10. The electronic control board assembly 20 not only provides power to other actuators within the ice maker body 10 but also coordinates the functions of each actuator. For example, the electronic control board assembly 20 is electrically connected to the controller of the ice maker body 10 and other actuators. The controller can regulate the electronic control board assembly 20 based on user input to the ice maker (e.g., to its user interface), input from various sensors located within the ice maker, and / or other suitable input commands. The electronic control board assembly 20 then converts the signals received from the controller into electrical control signals that can be understood by each actuator.

[0044] For the ice maker body 10, such as Figure 2 and Figure 3 As shown, in some embodiments, the ice maker body 10 includes a base 11, multiple protective shells 12, a body shell 13, a door assembly 14, an ice storage basket, an ice-making and ice-removing mechanism, a water supply assembly, and a refrigeration circulation assembly. The ice-making and ice-removing mechanism, the water supply assembly, and the refrigeration circulation assembly are all electrically connected to the electronic control board assembly 20.

[0045] The base 11, multiple protective shells 12, and the main body housing 13 are all included. The main body housing 13 is fixed to the base 11, and the multiple protective shells 12 are detachably connected to different sides of the main body housing 13 to enclose it. Optionally, the outer wall of the main body housing 13 is provided with multiple threaded holes and / or multiple snaps, and each protective shell 12 can be fixed to the outer wall of the main body housing 13 by means of, but not limited to, threads and / or snaps.

[0046] Meanwhile, the base 11, the housing 13, and multiple protective shells 12 together form an installation space that can accommodate the electronic control board assembly 20.

[0047] like Figure 6 As shown, the casing 13 defines an internal cavity, which can be divided into an ice-making area 13a, an ice storage area 13b, and a water recycling area 13c located below the ice storage area 13b. There is a height difference between the ice-making area 13a, the ice storage area 13b, and the water recycling area 13c. The ice-making area 13a can accommodate the ice-making and ice-removing mechanisms; the ice storage area 13b can accommodate the ice storage basket; and the water recycling area 13c can store the water used for ice making after the ice-making process.

[0048] For door assembly 14 and ice storage basket, such as Figure 3 As shown, in some embodiments, the door assembly 14 includes a door outer shell 141, a door inner shell 142, and a water-receiving plate 143. Specifically,

[0049] The door housing 141 is movably connected to the front protective housing 12. Optionally, the bottom of the door housing 141 is provided with a pivot (not shown), and the front protective housing 12 is provided with a retaining seat (not shown) at a position corresponding to the pivot. The retaining seat has a rotating hole that matches the shape of the pivot, and the pivot can be movably inserted into the rotating hole, realizing the movable connection between the door assembly 14 and the body housing 13. Compared with traditional drawer-type or side-opening methods, the flip-type opening and closing method is more suitable for operation in confined spaces, which can improve the flexibility of the ice maker.

[0050] The door outer shell 141 serves as a connection structure for the ice storage basket, which is detachably connected to the side of the door outer shell 141 facing the inner door shell 142. Optionally, the side of the door outer shell 141 facing the ice storage area 13b is provided with a first hook, the cross-sectional shape of which is approximately L-shaped. The side of the ice storage basket facing the door outer shell 141 is provided with a second hook, the cross-sectional shape of which is approximately inverted U-shaped. The second hook overlaps with the first hook, which not only achieves a detachable connection between the ice storage basket and the door outer shell 141, but also facilitates the assembly and disassembly of the ice storage basket in the vertical direction.

[0051] The inner shell 142 and the outer shell 141 are disposed opposite to each other, and a hollow cavity is defined between the outer shell 141 and the inner shell 142. The hollow cavity can impede heat transfer, reduce the influence of the external ambient temperature on the internal temperature of the cavity, reduce the workload of the compressor, and improve the energy efficiency of the ice maker. Optionally, the outer shell 141 is generally a cover structure that expands outward in the middle, and the periphery of the outer shell 141 facing the ice storage area 13b is provided with a recessed step. The shape of the inner shell 142 matches the inner contour shape formed by the recessed step, and the periphery of the inner shell 142 is provided with a protruding step that matches the recessed step. The protruding step can be fixed to the recessed step by adhesive, so that the inner shell 142 is embedded in the outer shell 141, so that the outer shell 141 and the inner shell 142 are disposed opposite to each other.

[0052] The inner shell 142 is a mounting and fixing structure for the water receiving plate 143. The water receiving plate 143 is installed on the side of the inner shell 142 away from the outer shell 141 and partially extends into the ice storage area 13b. The water receiving plate 143 can support the ice storage basket.

[0053] The ice-making and ice-shoveling mechanism is located at the top of the ice-making area 13a and is configured to flip towards the window to scoop out the produced ice. Specifically, the ice-making and ice-shoveling mechanism includes a water container and an ice-shoveling plate. Both the water container and the ice-shoveling plate are located within the ice-making area 13a. The support shaft of the water container is connected to the output shaft of the motor in sequence via a drive shaft, a connecting rod, and an eccentric component. The motor is fixed to the housing 13 and located within the installation space, and is electrically connected to the control board assembly 20. The ice-shoveling plate is hinged to the side of the water container facing the ice storage area 13b.

[0054] For the water supply assembly: The water supply assembly includes a water tank, a circulation pump, and circulation piping. The water tank is adjacent to one side of the protective housing 12 and connected to the water recovery area 13c. The circulation pump is electrically connected to the control board assembly 20 and is connected to the water recovery area 13c and the water collection box via the circulation piping.

[0055] The ice-making cycle assembly includes a compressor, condenser, dryer filter, evaporator, and return gas connection pipe. The compressor and condenser are located within the installation space and are both fixed to the base 11; the condenser is connected to the compressor. The evaporator is fixedly connected to the housing assembly and located above the water tank; 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 to the compressor through the return gas connection pipe.

[0056] To facilitate readers' 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.

[0057] First, the circulating pump receives an electrical signal from the electronic control board assembly 20 and turns on, continuously pumping the ice-making water in the water tank to the water container until it overflows and stops supplying water.

[0058] Simultaneously, or after the water in the water tank overflows, the compressor receives a command from the electronic control board assembly 20 to turn on. The refrigerant is output from the compressor's exhaust port and enters the condenser. The refrigerant is condensed in the condenser and then enters the dryer filter to be dried. The dried refrigerant enters the evaporator to cool the evaporator. The evaporator cools the water in the water tank through multiple ice-making tubes. The water in the water tank is gradually cooled and eventually freezes into ice over time and as the refrigeration cycle progresses.

[0059] 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.

[0060] Secondly, the motor receives the instruction from the control board assembly 20 and is turned on. The motor drives the transmission shaft, connecting rod, and eccentric component to rotate the water box toward the window. The ice scraper plate descends as the water box rotates. The water in the water box is poured into the water recycling area 13c, which is convenient for subsequent circulation pump recycling. The ice blocks are slightly heated and melted so that they fall onto the ice scraper plate under the action of gravity.

[0061] Furthermore, 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.

[0062] Finally, the outward-flipping door assembly 14, along with the ice storage basket, flips synchronously to expose it to the outside environment; the ice storage basket is lifted and removed in a direction away from the first hook to remove the ice stored in the ice storage basket.

[0063] For the electronic control board assembly 20, such as Figures 3 to 6 As shown, it is located within the installation space and abuts against the surface of the housing 13 opposite to the ice-making area 13a. Exemplarily, the control board assembly 20 includes a control box 21 and a control board 22. The control box 21 includes a front cover 211 and a rear cover 212. The front cover 211 is detachably connected to the surface of the housing 13 opposite to the ice-making area 13a, and the rear cover 212 is fitted inside the front cover 211, forming an installation cavity (not shown). The control box 21 serves as the mounting support structure for the control board 22 and is located within the installation cavity. The control board 22 is electrically connected to the motor that drives the water tank to rotate, the circulation pump, and the compressor.

[0064] The rear cover 212 is provided with a wiring hole 21b communicating with the interior of the ice maker body 10, allowing the connecting wires of each actuator to pass through. Optionally, there are at least two wiring holes 21b, which are respectively arranged on opposite sides of the control box 21. Exemplarily, there are four wiring holes 21b, which are arranged in pairs on opposite sides of the control box 21.

[0065] like Figure 6As shown, in some embodiments, the surface of the housing 13 facing away from the ice-making area 13a has a slot 131, and the electrical control box 21 has a plug-in part 23, which is inserted into the slot 131. The electrical control box 21 is fixed to the housing 13 by a first fastener 31. Optionally, the plurality of protective shells 12 include a rear protective shell 12, which is disposed opposite to the surface of the housing 13 facing away from the ice-making area 13a. The surface of the housing 13 facing away from the ice-making area 13a has a slot 131 and a first nut post 132, which are spaced apart. The extension direction of the slot 131 is parallel to the rear protective shell 12, and the extension direction of the first nut post 132 is perpendicular to the rear protective shell 12. The front cover 211 has an assembly hole 211a on the side wall facing the housing 13. The first fastener 31 passes through the assembly hole 211a and is screwed to the first nut post 132 to achieve the assembly and fixation of the electronic control board assembly 20 and the body housing 13. Exemplarily, there are two slots 131 and two first nut posts 132. The two slots 131 and two first nut posts 132 are respectively located around the surface of the body housing 13 away from the ice-making area 13a. The two plug-in parts 23 are inserted into the two slots 131 one by one. The two first fasteners 31 pass through the two assembly holes 211a one by one and are screwed to the two first nut posts 132 respectively.

[0066] To facilitate the installation and fixation of the electronic control board assembly, in some embodiments, the surface of the housing 13 facing away from the ice-making area 13a is provided with supporting ribs, and the front cover 211 abuts against the supporting ribs. By providing supporting ribs on the surface of the housing 13 facing away from the ice-making area 13a to support the front cover 211, when the connecting harnesses of each actuator are plugged into and fixed to the electronic control board 22, excessive plugging force during plugging can be prevented from causing warping and damage to the electronic control board assembly. At the same time, the supporting ribs have a certain slope in their extension direction due to the need for demolding.

[0067] Please combine Figure 10 See also Figure 4The front cover 211 has a recessed portion of its sidewall facing the fuselage housing 13, which is recessed towards the rear protective shell 12 to form an inner recess 2111. The position of the inner recess 2111 corresponds to the first nut post 132, and the cross-sectional shape of a portion of the inner recess 2111 matches the end cross-sectional shape of the first nut post 132. For example, the number of inner recesses 2111 is the same as the number of first nut posts 132, so that two portions of the two first nut posts 132 are respectively fitted into the two inner recesses 2111. Each inner recess 2111 has a aforementioned mounting hole 211a, and each first fastener 31 passes through the mounting hole 211a and is screwed to the first nut post 132. The advantage of this design is that when the control board assembly 20 is inserted into the ice maker body 10 through the plug-in part 23, the positioning cooperation between the first nut post 132 and the recessed part 2111 can prevent the control board assembly 20 from falling off in the opposite direction to the insertion direction, so that the subsequent first fastener 31 can fasten the control board assembly 20 and the body housing 13.

[0068] like Figure 6 As shown, the top surface of the housing 13 extends outward to form a perimeter 133, and the rear protective shell 12 is detachably connected to this perimeter 133. A slot 131 is located at the junction of the perimeter 133 and the surface of the housing 13 facing away from the ice-making area 13a. In this technical solution, the slot 131 is arranged at the junction of the perimeter 133 and the housing 13, allowing the inserted plug 23 to receive better support on two or more contact surfaces, and to distribute the load on the electronic control board assembly 20 through two or more contact surfaces, thereby reducing loosening of the electronic control board assembly 20 during use.

[0069] Please combine Figures 7 to 10 See also Figure 4 or Figure 5 In some embodiments, the front cover 211 includes a main body 2101 and a shield 2102. The rear cover 212 is fitted into the main body 2101 and forms a mounting cavity with the main body 2101. The shield 2102 surrounds the periphery of the main body 2101 and can shield the electrical control box 21. The aforementioned wiring hole is provided in the main body 2101 and communicates with the mounting cavity, and the aforementioned plug-in portion 23 is provided on the top of the shield.

[0070] For example, the cross-sectional shape of the shield 2102 and the main body 2101 is approximately inverted U-shaped. The main body 2101 includes a top wall 21021, which is located on top of the main body 2101. A portion of the shield 2102 is integrally connected to the top wall 21021. The rear cover 212 includes an upper wall 2120, which is disposed opposite to the top wall 21021. The length of the upper wall 2120 is less than or equal to the length of the top wall 21021. When the electronic control board assembly is assembled on the housing 13, the top surface of the housing 13 is affected by the low temperature of the ice-making area 13a, causing condensate to drip onto the electronic control board assembly. By providing a shield 2102 that extends beyond or is flush with the rear cover 212, the condensate can be prevented from splashing into the mounting cavity.

[0071] Furthermore, please combine Figure 8 Referring also to 5, the upper wall 2120 gradually slopes upward toward the fuselage. In this technical solution, even if residual condensate flows to the rear cover 212 through the shield 2102, the residual condensate can still be discharged outside the electrical control box 21 because the upper wall 2120 is inclined.

[0072] like Figures 5 to 10 As shown in any of the accompanying drawings, the front cover 211 includes a cover portion 2103. The cover portion 2103 protrudes from the side of the shielding portion 2102 and is adjacent to the wiring hole 21b, and the cover portion 2103 can shield the wiring hole 21b. Exemplarily, a notch forming part of the wiring hole 21b is formed on the side wall adjacent to the top wall 21021. The cover portion 2103 is generally ear-shaped and includes a first ear plate 21031 and a second ear plate 21032 connected to each other, and the first ear plate 21031 and the second ear plate 21032 are respectively connected to the adjacent side wall of the notch. In this technical solution, the first ear plate 21031 is inclined downward, and the condensate dripping onto the shielding cover 2102 can slide down the first ear plate 21031 and out of the wiring hole 21b, thereby preventing the condensate from entering the mounting cavity along the wiring hole 21b. Furthermore, the second ear plate 21032 has at least two fixing holes spaced apart to facilitate the constraint of the connection harnesses of each actuator.

[0073] It is understood that the embodiments of this application do not specifically limit the structure of the cover 2103 or the connection method between the cover 2103 and the shielding part 2102, as long as the cover 2103 can shield the wiring hole 21b to prevent condensate from entering the mounting cavity along the wiring hole 21b. For example, in some other embodiments, the cover 2103 is an independent structural component, which is fixed to the side of the shielding part 2102 by means of, but not limited to, screwing, fastening, or bonding.

[0074] Please combine Figure 9 See also Figure 7To facilitate the installation and fixation of the electronic control board 22, in some embodiments, the side wall surface of the front cover 211 facing the mounting cavity is provided with positioning posts 2112, snap fasteners 2113, and multiple second nut posts 2114. The electronic control board 22 has multiple through holes 22a and multiple second nut posts 2114. The positioning posts 2112 pass through the positioning holes, and the electronic control board 22 is fastened to the snap fasteners 2113. Multiple second fasteners 32 pass through the multiple through holes 22a one by one and are screwed and fixed to the multiple second nut posts 2114 respectively. In this technical solution, the electronic control board 22 is pre-positioned by the positioning posts 2112 and snap fasteners 2113, which reduces the assembly difficulty of subsequently screwing the electronic control board 22 to the front cover 211 with the second fasteners 32.

[0075] Furthermore, the plurality of through holes 22a includes a first through hole 221a, which is located at a corner of the electronic control board 22. The rear cover 212 has a recessed sidewall facing the mounting cavity to form a guide post 2121, which abuts against the surface of the electronic control board 22. The guide post 2121 has a guide hole, through which a second fastener 32 passing through the first through hole 221a is exposed.

[0076] Next, to facilitate the reader's understanding of the electronic control board assembly involved in this application, its assembly process will be described in detail. Specifically, as follows:

[0077] The first step is to position and install the electronic control board 22 on the front cover 211 by the positioning post 2112, and to achieve the pre-installation of the electronic control board 22 by the snap fastener 2113 inside the front cover 211.

[0078] The second step is to tighten multiple second fasteners 32 to lock the electronic control board 22 to the second nut post 2114 of the front cover 211;

[0079] The third step is to insert the plug-in part 23 into the slot 131 and embed the first nut post 132 into the recess 2111 to achieve the pre-installation of the combined structure of the electronic control board 22 and the front cover 211.

[0080] Fourth step, tighten the first fastener 31 to lock the combined structure of the electronic control board 22 and the front cover 211 onto the surface of the body shell 13 away from the ice-making area 13a; wherein, some of the first fasteners 31 pass through the corner of the electronic control board 22 while locking the front cover 211, to reinforce the electronic control board 22, avoiding the need to tighten the corner separately and thus adding installation steps.

[0081] The fifth step is to plug and fix the connection harnesses of each actuator to the control board 22, and use straps to pass through the fixing holes to constrain the connection harnesses of each actuator.

[0082] The sixth step is to insert the rear cover 212 into the front cover 211 and tighten the second fastener 32 to complete the assembly and fixation of the rear cover 212.

[0083] Step 7: Lock the rear protective shell 12 onto the body shell 13 to complete the assembly and fixation of all parts of the ice maker.

[0084] In summary, in the ice maker of this application, the control board assembly 20 is inserted into the slot 131 via the plug-in part 23, and the relative movement between the control board assembly 20 and the ice maker body 10 is restricted by the first fastener 31, thereby assembling and fixing the control board assembly 20 to the ice maker body 10. Therefore, when disassembling and assembling the control board assembly 20, it is only necessary to remove one of the protective shells 12 and then remove the first fastener 31 to easily remove the control board assembly.

[0085] In addition, a guide post 2121 is provided at the corner position of the rear cover 212 corresponding to the corner position of the electronic control board 22, so as to facilitate the screwing and fixing of the rear cover 212 to the front cover 211; on this basis, the guide post 2121 abuts against the corner position of the electronic control board 22, thereby completing the reinforcement of the corner position of the electronic control board 22, and also eliminating the need for additional separate reinforcement of the corner position of the electronic control board 22 during installation.
