Description

Technical Field

[0001] This disclosure generally relates to the field of thermodynamics. In particular, but not exclusively, this disclosure relates to ice makers. Furthermore, embodiments of this disclosure disclose a removable evaporator assembly for use in an ice maker, which is used with a mechanism for easily removing a metal plate from the evaporator assembly. Background Technology

[0002] Ice is formed by exposing water to sub-zero temperatures. When water is exposed to freezing temperatures, it changes from a liquid to a solid state. Ice of different shapes and sizes can be produced using molds of predetermined shapes. First, water to be frozen is poured into a mold of a predetermined shape. The mold is then exposed to sub-zero temperatures that cause the water in the mold to freeze. As the water solidifies, it takes the shape of the mold and thus produces ice blocks in that shape. Typically, household refrigerators use ice trays with a more conventional cubic shape, where both the refrigerator and the ice tray are suitable for producing small quantities of ice. However, certain industries, such as the food, beverage, and cold storage industries, use large quantities of ice with specific requirements in terms of shape and size. Smaller-sized ice is often used in the food / beverage industry, such as restaurants and hotels. In recent years, the demand for ice in the food and beverage industry has increased. Therefore, the food / beverage industry needs to produce large quantities of ice in a short period of time. The availability of ice in different shapes in the food and beverage industry also seems to satisfy consumers.

[0003] Typically, ice is produced by pouring water or liquid into molds of a predetermined shape, which are then subjected to sub-zero temperatures to form ice. However, this process is time-consuming and tedious, making it difficult to produce large quantities of ice. Furthermore, conventionally produced ice may crack during collection.

[0004] With technological advancements, automatic ice makers have been developed and are used in many industries. These automatic ice makers minimize human intervention by producing ice of the desired shape and size. Ice makers are often suited for industries that require large quantities of ice, such as the food or beverage industries. An ice maker includes a fluid tank that stores water to be frozen. Water from the fluid tank is pumped to a water flow pipe. The water from the water flow pipe further flows to multiple cooling surfaces on an evaporator. The multiple cooling surfaces of the evaporator may include a first conductive plate and a second conductive plate. A refrigerant pipe may be positioned between the first and second conductive plates. Furthermore, the first conductive plate, the second conductive plate, and the refrigerant pipe may be connected by a thermal bonding process such as soldering or brazing. As the refrigerant flows through the refrigerant pipe, the water flowing on the outer surfaces of the first and second conductive plates turns into ice because heat from the water is absorbed by the refrigerant pipe through the first and second conductive plates. The first and second conductive plates form a cooling surface that cools and freezes the water flowing on them. As water freezes on the cooling surface, the forming ice takes the shape of refrigerant tubes and forms semi-cylindrical ice blocks. The ice is further collected by circulating hot water on the inner surfaces of the metal plates and refrigerant tubes. Fresh water partially melts the ice forming on the surfaces of the first and second conductive plates, causing it to fall into the storage container.

[0005] In the aforementioned evaporator design, the first and second conductive plates are securely connected to the refrigerant pipes by soldering. The first and second conductive plates are configured to face each other, and the refrigerant pipes are positioned between them. Because the refrigerant pipes, the first and second conductive plates are securely welded together, the evaporator cannot be easily disassembled. Furthermore, due to the constant water flow on the surface of the refrigerant pipes during the collection cycle, bacterial formation on the refrigerant pipes becomes urgent. Cleaning the outer surface of the refrigerant pipes is generally impossible due to inaccessibility. Since all components of the evaporator are welded together, disassembling the evaporator to clean the bacterial formation on the refrigerant pipe surfaces is also impossible. Therefore, extremely strong cleaning agents are often used to remove the bacterial formation on the refrigerant pipes, and these agents sometimes mix with the water flow during the collection cycle, thus contaminating the formed ice. Because the bacteria formed on the surface of the refrigerant pipes cannot be cleaned due to inaccessibility, the water flowing over the contaminated surface will also be contaminated. When the same contaminated water is reused for ice formation, the resulting ice will be extremely unsanitary.

[0006] Furthermore, in conventional evaporator assemblies as described above, heat from the flowing water is typically absorbed by the refrigerant in the refrigerant tubes via intermediate surfaces such as the first and second conductive plates. These plates are typically made of low-conductivity metals such as stainless steel, which is not a good conductor, thus significantly reducing the overall efficiency of the evaporator assembly. Consequently, the total cold storage energy of the refrigerant required to cool the flowing water is significantly increased. Moreover, since heat transfer between the refrigerant tubes and the flowing water occurs through the intermediate first and second conductive plates, the operating temperature of the refrigerant flowing through the refrigerant tubes must be significantly reduced, or the duration of refrigerant circulation through the refrigerant tubes must be significantly increased to allow ice to form on the first and second conductive plates. Therefore, conventional evaporator assemblies typically require more time to produce ice, and the subsequent operating temperature of the refrigerant will be significantly lower. Consequently, the overall operating cost of the evaporator assembly is significantly increased.

[0007] This disclosure is intended to overcome one or more of the foregoing limitations or any other limitations associated with conventional technology. Summary of the Invention

Detailed Implementation

[0045] The features and technical advantages of this disclosure have been extensively outlined above to facilitate a better understanding of the following description of its contents. Additional features and advantages of this disclosure, which form the subject matter of this disclosure, will be described below. Those skilled in the art will understand that the disclosed concepts and specific embodiments can be readily used as a basis for modifications or designs for other devices intended to carry out the same purposes of this disclosure. Those skilled in the art will also recognize that such equivalent constructions do not depart from the spirit and scope of this disclosure. The novelty features, as well as other objects and advantages considered to be features of this disclosure in terms of its structure, will be better understood from the following description when considered in conjunction with the accompanying drawings. However, it should be clearly understood that each drawing in the accompanying drawings is provided for illustrative and descriptive purposes only and is not intended to limit the scope of this disclosure.

[0046] In this document, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation or embodiment of the subject matter described as "exemplary" herein is not necessarily to be construed as superior to or more advantageous than other implementations.

[0047] While this disclosure is readily adaptable to various modifications and alternatives, specific embodiments of this disclosure have been illustrated by way of example in the accompanying drawings and will be described below. However, it should be understood that this disclosure is not intended to limit it to the specific forms disclosed, but rather, it will cover all modifications, equivalents, and alternatives falling within its scope.

[0048] The terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a component that includes a list of parts includes not only those parts but may also include other parts not expressly listed or inherent to such a component. In other words, one or more elements in a device or component expressed by “comprising…” do not exclude the presence of other elements or additional elements in the component without further constraints.

[0049] This disclosure discloses a mechanism for a removable metal plate in an evaporator component of an ice maker. Conventionally, heat from flowing water is absorbed by the refrigerant in the refrigerant tube through an intermediate surface. This intermediate surface can be the surface of the refrigerant tube itself and the surface of either the first or second metal plate. Because heat transfer between the refrigerant tube and the flow of water occurs through the intermediate plate, the operating temperature of the refrigerant flowing through the refrigerant tube must be significantly reduced. This reduces the efficiency of the ice maker and increases the overall operating cost of the evaporator assembly. Furthermore, the refrigerant tube, the first metal plate, and the second metal plate of the evaporator are firmly welded together because the evaporator cannot be disassembled. Additionally, the constant water flow on the surface of the refrigerant tube during the collection cycle leads to bacterial formation on the refrigerant tube, resulting in the formation of unsanitary ice.

[0050] Therefore, this disclosure discloses an evaporator assembly for an ice maker. The evaporator assembly includes a first metal plate and a second metal plate that receive a refrigerant pipe. The first and second metal plates define a plurality of protrusions extending from a first main surface. Each of the plurality of protrusions defines a groove in a second main surface opposite to the first main surface of the corresponding first and second metal plates. One or more grooves defined in the second main surface of the first metal plate include a plurality of first connectors, and one or more grooves defined in the second main surface of the second metal plate include a plurality of second connectors. The second main surface of each of the first and second metal plates contacts the refrigerant pipe when the first and second metal plates are joined. At least one of the first and second metal plates is movable relative to the other such that the plurality of first connectors and the plurality of second connectors engage with each other to secure the first and second metal plates when at least one of the first and second metal plates moves in a first direction. The plurality of first connectors and the plurality of second connectors disengage from each other and separate the first and second metal plates when the first and second metal plates move in a second direction.

[0051] The following paragraphs refer to Figures 1 to 11 This disclosure describes the content of this publication. Figure 1 The illustration shows a front perspective view of the removable evaporator assembly (100), and Figure 2The illustration shows a top perspective view of a removable evaporator assembly (100). The evaporator assembly (100) includes a refrigerant pipe (3) disposed or positioned between a first metal plate (1) and a second metal plate (2). The first metal plate (1) and the second metal plate (2) are configured to define a plurality of first protrusions (1x) and a plurality of second protrusions (2x), respectively. The first metal plate (1) and the second metal plate (2) may define a plurality of protrusions (1x and 2x) extending from a first main surface (19), wherein each of the plurality of protrusions (1x and 2x) may define a groove (S) in a corresponding second main surface (20) opposite to the first main surface (19) of the corresponding first metal plate (1) and the second metal plate (2). A first metal plate (1) and a second metal plate (2) are formed or stamped such that a plurality of first protrusions (1x) on the first metal plate (1) and a plurality of second protrusions (2x) on the second metal plate (2) extend vertically through the length of the first metal plate (1) and the second metal plate (2), respectively. The plurality of first protrusions (1x) defined on the first metal plate (1) and the plurality of second protrusions (2x) defined on the second metal plate (2) may be equidistant from each other, and the plurality of first protrusions (1x) and the plurality of second protrusions (2x) may have a V-shape. The plurality of first protrusions (1x) and the plurality of second protrusions (2x) extending vertically along the first metal plate (1) and the second metal plate (2) may serve as walls defining a plurality of ice-forming surfaces (Z) for forming a plurality of ice blocks. Furthermore, multiple cuts (16) can be engraved in the internal sections of the first metal plate (1) and the second metal plate (2), and the multiple cuts (16) extend horizontally through the length of the first metal plate (1) and the second metal plate (2) or extend horizontally at at least one position along the length of the first metal plate (1) and the second metal plate (2). Figure 9[Clearly visible]. Cutouts (16) etched in the first metal plate (1) and the second metal plate (2) can be constructed at the top of the V-shaped protrusions (1x and 2x) and along the ice-forming surface (Z) of the first metal plate (1) and the ice-forming surface (Z) of the second metal plate (2). Cutouts (16) etched in the first metal plate (1) and the second metal plate (2) can each have a semi-circular shape, and cutouts (16) can form a complete circular channel when the first metal plate (1) and the second metal plate (2) are aligned together. Circular cutouts (16) can extend along the central region of the evaporator assembly (100), and cutouts (16) etched into the first metal plate (1) and the second metal plate (2) can be configured to compactly accommodate refrigerant pipes (3). Refrigerant pipes (3) protrude outward from cutouts (16) in the first metal plate (1) and the second metal plate (2). The refrigerant tube (3) receives dispersed water to form ice (11) on the refrigerant tube (3), giving the ice (11) formed on the refrigerant tube (3) a semi-circular shape. The semi-circular cutouts (16) etched into the first metal plate (1) and the second metal plate (2) may have the same diameter as the refrigerant tube (3) or a diameter slightly larger than the size of the refrigerant tube (3), such that the refrigerant tube (3) is suitably accommodated inside the cutouts (16). The front end of the first metal plate (1) may be configured to define at least one first flange (17), and the second metal plate (2) may also be configured to define at least one second flange (18). The first flange (17) and the second flange (18) may be defined in a direction perpendicular to the ice-forming surface (Z). The first flange (17) and the second flange (18) may be integral parts of the first metal plate (1) and the second metal plate (2), respectively, and may be formed by stamping or deformation in a direction perpendicular to the ice-forming surface (Z). Figure 1 As can be seen, the first flange (17) and the second flange (18) can extend between the refrigerant pipes (3). Furthermore, each of the plurality of first flanges (17) may define a first hole (5a) or opening extending through the first flange (17), and each of the plurality of second flanges (18) may define a second hole (5b) extending through the second flange (18). [From...] Figure 8[Clearly visible in the image]. The first hole (5a) on the first flange (17) and the second hole (5b) on the second flange (18) can be configured to be oriented along the same axis when the first flange (17) and the second flange (18) are positioned adjacent to each other. The first hole (5a) on the first flange (17) and the second hole (5b) on the second flange (18) can accommodate a second fastener (5). In an embodiment, the second fastener (5) is a clamping screw. The second fastener (5) can be defined with threads that match the threads of the first hole (5a) and the second hole (5b). The second fastener (5) can be fastened into the first hole (5a) on the first flange (17) and the second hole (5b) on the second flange (18), such that the first flange (17) is securely connected to the second flange (18). Furthermore, the second flange (18) can be defined with a third hole (4a) extending through the second flange (18). The third hole (4a) can be configured to receive the first fastener (4), and the thread of the third hole (4a) can engage with the thread defined on the first fastener (4). Further reference is made to... Figure 2 The rear end of the first metal plate (1) can be constructed or deformed to form a U-shaped shell (21), and the rear end of the second metal plate (2) can be an elongated member housed within the shell (21) of the first metal plate (1).

[0052] One or more grooves (S) defined in the second main surface (20) of the first metal plate (1) accommodate a plurality of first connectors (6a), and one or more grooves (S) defined in the second main surface (20) of the second metal plate (2) accommodate a plurality of second connectors (6b). The inner surfaces of each of the V-shaped first protrusion (1x) and second protrusion (2x) may be respectively provided with a plurality of first connectors (6a) and a plurality of second connectors (6b). For example, from... Figure 2As can be seen, each of the V-shaped first protrusions (1x) on the first metal plate (1) has a plurality of first connectors (6a) on its inner surface. The plurality of first connectors (6a) can extend through the length of each of the first protrusions (1x) on the first metal plate (1). Furthermore, the plurality of first connectors (6a) can be C-shaped members with mechanical coupling devices (7). In this embodiment, the mechanical coupling device (7) is a first tensioning member (7a). The plurality of first connectors (6a) can be firmly connected to the inner surface of the first protrusions (1x) by a thermal bonding process, such as welding. Similarly, each of the V-shaped second protrusions (2x) on the second metal plate (2) has a plurality of second connectors (6b) on its inner surface. The plurality of second connectors (6b) can extend through the length of each of the second protrusions (2x) on the second metal plate (2). Furthermore, the plurality of second connectors (6b) may be C-shaped members with mechanical engagement devices, wherein the mechanical engagement devices are second tensioning members (7b). The plurality of second connectors (6b) may be securely connected to the inner surface of the second protrusion (2x) by a thermal bonding process, such as welding.

[0053] The refrigerant pipe (3) is fitted between the first metal plate (1) and the second metal plate (2) such that the refrigerant pipe (3) is received within a cutout (16) provided in the first metal plate (1) and the second metal plate (2). The first metal plate (1) and the second metal plate (2) are also held together by a plurality of first connectors (6a) and a plurality of second connectors (6b). A first tensioning member (7a) from the plurality of first connectors (6a) frictionally contacts a second tensioning member (7b) from the plurality of second connectors (6b). Assembling the evaporator assembly (100) includes aligning the first metal plate (1) and the second metal plate (2) adjacent to each other along the refrigerant pipe (3). The next step includes sliding at least one of the first metal plate (1) and the second metal plate (2) along a first direction (X) such that the plurality of first connectors (6a) and the plurality of second connectors (6b) removably engage with each other to secure the first metal plate (1) and the second metal plate (2). When assembling the first metal plate (1), the second metal plate (2), and the refrigerant pipe (3), the first metal plate (1) or the second metal plate (2) can be slid on another plate such that a plurality of second connectors (6b) are removably engaged with a plurality of first connectors (6a) and such that the extension at the rear end of the second metal plate (2) is accommodated within the housing (21) of the first metal plate (1). Therefore, the tension between the first tensioning member (7a) and the second tensioning member (7b) ensures that the plurality of first connectors (6a) and the second connectors (6b) remain together. Thus, the first connectors (6a) housed in the protrusions (1x) of the first metal plate (1) and the plurality of second connectors (6b) housed in the protrusions (2x) of the second metal plate (2) ensure that the first metal plate (1) and the second metal plate (2) are held together by the tension between the first tensioning member (7a) and the second tensioning member (7b). Once the first metal plate (1) and the second metal plate (2) are held together by a plurality of first connectors (6a) and a plurality of second connectors (6b), the first fastener (4) can be further fastened into the first hole (5a) of the first flange (17) and the second hole of the second flange (18), thereby connecting the first metal plate (1) and the second metal plate (2).

[0054] In this embodiment, the first metal plate (1) and the second metal plate (2) are made of a low thermal conductivity material, such as stainless steel, and the refrigerant pipe (3) is made of a metal with high thermal conductivity, such as nickel-coated copper. In this embodiment, limiting the amount of copper used in the refrigerant pipe (3) ensures a minimum amount of copper per kg capacity of the ice maker and thus achieves an efficient and economical design of the evaporator assembly (100).

[0055] Figure 3 and Figure 4The diagram shows a side view and a front perspective view of the evaporator assembly (100) during a cooling cycle. As shown, multiple water flow channels (8) can be constructed on top of the evaporator assembly (100). The water flow channels (8) can be configured to disperse water onto the ice-forming surface (Z) of the first metal plate (1), the ice-forming surface (Z) of the second metal plate (2), and the refrigerant pipe (3). Furthermore, the refrigerant can be properly circulated through the refrigerant pipe (3). From the fluid tank (14) [from Figure 10 [See image] Water can be pumped into multiple water flow pipes (8). Water from the water flow pipes (8) flows through multiple openings at the bottom of the water flow pipes (8) onto multiple ice-forming surfaces (Z). From Figure 3 The flow of water during the cooling cycle is clearly visible. Furthermore, the water flows over multiple ice-forming surfaces (Z) and comes into direct contact with the surfaces (B) of multiple refrigerant pipes (3). Because the water from the water flow pipes (8) is directly guided to the surfaces (B) of the refrigerant pipes (3), ice forms at a faster rate. Furthermore, the overall operating efficiency of the evaporator assembly (100) increases because the surfaces (B) of the refrigerant pipes (3) are in direct contact with the flowing water. When water encounters the surfaces (B) of the refrigerant pipes (3), the water freezes into ice and forms hemispherical ice blocks on either side of the refrigerant pipes (3). As water continues to flow over the surfaces (B) of the refrigerant pipes (3), additional ice layers form on top of the existing ice layers.

[0056] As from Figure 4 As can be seen, multiple semi-cylindrical ice blocks are formed around the surface (B) of the refrigerant pipe (3), the ice-forming surface (Z) of the first metal plate (1), and the ice-forming surface (Z) of the second metal plate (2). (See image from...) Figure 3As can be seen, during the cooling cycle, the water flow is first directed to multiple ice-forming surfaces (Z) and the surface (B) of the refrigerant pipe (3). The water flows onto the refrigerant pipe (3), where the refrigerant in the refrigerant pipe (3) absorbs heat from the water and causes the water to freeze on the surface (B) of the refrigerant pipe (3). Thus, ice forms directly on the surface of the refrigerant pipe (3). Furthermore, when additional water circulates through the ice-forming surfaces (Z) of the first metal plate (1) and the second metal plate (2), the water further freezes on the already formed ice layer on the refrigerant pipe (3). Thus, ice gradually forms in layers. As the ice layer formed around the refrigerant pipe (3) increases, the ice gradually takes on a semi-cylindrical shape. Water gradually flows over all the surfaces (B) of the refrigerant pipe (3). Water that is not frozen or solidified on the first surface (B1) of the refrigerant pipe (3) flows to the next or second surface (B2) of the refrigerant pipe (3). Furthermore, only a certain amount of water flowing on the second surface (B2) freezes, while excess water flows to the third surface (B3) via the ice-forming surface (Z). This water flow continues through all surfaces (B) of the refrigerant pipe (3). Any remaining water that does not freeze or solidify on the last surface (B4) of the refrigerant pipe (3) flows into the fluid tank (14) / water tank located below the evaporator assembly (100).

[0057] Therefore, ice forms gradually layer by layer until a complete semi-cylindrical ice block is obtained. Since the refrigerant tube (3) is directly used as the base surface (B) for ice formation, the heat transfer between the water flowing on the refrigerant tube (3) and the refrigerant inside the refrigerant tube (3) is sufficient. Furthermore, since the surface (B) of the refrigerant tube (3) itself is directly used as the ice-forming surface, there is minimal heat loss while the water freezes into ice. Therefore, the rate or time required for ice formation is greatly increased, and the overall operating efficiency of the evaporator assembly (100) is also improved.

[0058] Figure 5 and Figure 6 The illustration shows a side view of the evaporator assembly (100) during the collection cycle. (See diagram.) Figure 5As can be seen, a fresh water pipe (9) is provided on top of the evaporator assembly (100). Defrosting fluid is supplied to the fresh water pipe (9) by means of a pump from the defrosting fluid tank or any other suitable device. The defrosting fluid can circulate between the first metal plate (1) and the second metal plate (2) so that the defrosting fluid falls directly onto the inner surface of the refrigerant pipe (3) and the inner surfaces of the first metal plate (1) and the second metal plate (2). The defrosting fluid is fresh water and is generally at a high temperature. The defrosting fluid is dispersed such that the defrosting fluid is in direct contact with the inner surface of the refrigerant pipe (3) and the inner surfaces of the first metal plate (1) and the second metal plate (2). The defrosting fluid is sprayed onto the multiple refrigerant pipes (3) by a suitable device. The defrosting fluid is sprayed onto the multiple refrigerant pipes (3) only when it is completely frozen. At the beginning of the defrosting cycle, hot refrigerant fluid begins to flow through the refrigerant pipes (3), and the total temperature of the refrigerant pipes (3) rises when the hot defrosting fluid comes into contact with the refrigerant pipes (3). The temperature rise of the refrigerant pipes (3) causes the ice formed on the surfaces (B) of the multiple refrigerant pipes (3) to partially melt. As the ice partially melts from the surfaces (B) of the refrigerant pipes (3), the ice separates from the surfaces (B) of the multiple refrigerant pipes (3). Figure 5 As can be seen, the ice blocks that are separating from the refrigerant pipe (3) are gradually falling.

[0059] In embodiments of this disclosure, the defrosting fluid can circulate directly through multiple refrigerant lines (3) during the collection cycle.

[0060] In embodiments of this disclosure, the cooling cycle and the collection cycle can be operated for predetermined time periods, wherein the predetermined time periods can be the minimum time required for ice to form during the cooling cycle and the minimum time required for the ice to separate from the refrigerant line (3) during the collection cycle. The water level can be controlled during the cooling cycle, and the evaporator temperature can be controlled by a control unit during the defrosting cycle.

[0061] In embodiments of this disclosure, the surface of the refrigerant tube (3) may be coated with nickel or any other suitable non-corrosive, durable, food-grade electrolytic coating to prevent erosion and / or corrosion, thereby avoiding the formation of bacteria on the surface (B) of the refrigerant tube (3).

[0062] Multiple cooling and collection cycles can be completed, and the evaporator assembly (100) must be cleaned after a predetermined number of cycles. After multiple cooling and collection cycles, if the evaporator is not properly cleaned, a large amount of bacteria may accumulate on the surface (B) of the refrigerant pipe (3) and on the rear surfaces (Z) of the first metal plate (1) and the second metal plate (2). Therefore, disassembly and cleaning of the evaporator assembly (100) becomes necessary. Furthermore, due to the continuous flow of water through the multiple first connectors (6a) and second connectors (6b), a large amount of calcium in the water may accumulate on the connectors (6) and other joints of the evaporator assembly (100). For example, a large amount of calcium may deposit between the first flange (17), the second flange (18), and the connector (6), thus making disassembly difficult. Therefore, the evaporator assembly (100) is disassembled for cleaning as described below.

[0063] Reference Figure 6 The angle of incidence of the defrosting fluid is in the range of 18 to 22 degrees. The angle of incidence is defined between: a line perpendicular to the top surface of the refrigerant pipe (3); and a line tangent to the surface of the refrigerant pipe (3) that contacts at least one of the first metal plate (1) and the second metal plate (2). Typically, the defrosting fluid flows between the first metal plate (1) and the second metal plate (2), such as from… Figure 6 As indicated by the dotted line, the defrosting fluid contacts the outer surface of the refrigerant pipe (3) and heats the refrigerant inside the refrigerant pipe (3). Subsequently, the ice (11) is partially heated and released from the evaporator assembly (100) in the manner described above. Furthermore, the first metal plate (1) and the second metal plate (2) are spaced apart such that the incident angle (X) of the defrosting fluid can be between 18 degrees and 22 degrees, preferably 20 degrees. Therefore, the defrosting fluid falling on the refrigerant pipe (3) is exposed to a larger surface area of ​​the refrigerant pipe (3). Therefore, the rate at which the defrosting fluid heats the refrigerant inside the refrigerant pipe (3) is significantly higher. Therefore, the ice is heated at a faster rate and separates from the outer surface of the refrigerant pipe (3). Since the above-described configuration of the first metal plate (1) and the second metal plate allows the incident angle (X) of the defrosting fluid to be equal to 20 degrees, the rate of ice collection is significantly increased. Furthermore, because the collection cycle is faster and the amount of ice produced is significantly higher with the above configuration, the number of cooling and collection cycles per day increases dramatically. Experiments showed that the collection cycle with this configuration only takes about 45 seconds.

[0064] Now refer to Figure 7 and Figure 8 , Figure 7 and Figure 8 The diagrams show both an assembled top perspective view and a disassembled view of the evaporator assembly (100). Furthermore, Figure 9The illustration shows a front perspective view of the evaporator assembly (100) after disassembly. Figure 7 As shown, the second fastener (5) is initially not fastened to the first hole (5a) of the first flange (17) and the second hole (5b) of the second flange (18). (See diagram from...) Figure 7 As can be seen, the second fastener (5) can be rotated counterclockwise and can be completely removed from the first flange (17) and the second flange (18). Figure 8 and Figure 9 As can be seen, once the second fastener (5) is removed, the first fastener (4) can be rotated clockwise. In this embodiment, the first fastener (4) is referred to as a pull-out screw. The first fastener (4) is constructed as a single third hole (4a) through the second flange (18). The first flange (17), constructed adjacent to and behind the second flange (18), does not include any holes for receiving the first fastener (4). Therefore, tightening the first fastener (4) brings it into direct contact with the first flange (17). Figure 7 and Figure 8 As can be seen, when the first fastener (4) is further tightened, the rear end of the first fastener (4) pushes against the first flange (17), thereby causing the first flange (17) to separate or disconnect from the second flange (18) along the second direction (Y). When the first flange (17) is pushed open along the second direction (Y) due to the tightening of the first fastener (4), the first metal plate (1) also slides backward. Therefore, the first tensioning member (7a) of the first connector (6a) slides away from the second tensioning members (7b) of the plurality of second connectors (6b), and the first metal plate (1) disconnects from the second metal plate (2). Therefore, when excessive calcium or other mineral deposits hinder the disassembly of the evaporator assembly (100), the first fastener (4) assists in disassembling the first metal plate (1) from the second metal plate (2).

[0065] Figure 10An exploded view of the evaporator assembly (100) is shown. Once the evaporator assembly (100) is disassembled as described above, the first metal plate (1), the second metal plate (2), and the refrigerant pipe (3) can be easily cleaned. Since the evaporator assembly (100) is completely disassembled, all parts and surfaces of the evaporator assembly (100) can be easily accessed, and a thorough cleaning of each component in the evaporator assembly (100) can be achieved. Therefore, regular maintenance of the evaporator assembly (100) ensures that no bacteria form on the ice-forming surface (Z) or on the refrigerant pipe (3), resulting in unsanitary operating conditions. The above-described configuration of the connector (6), flanges (17 and 18), first fastener (4), and second fastener (5) allows the user to disassemble the evaporator assembly (100) for regular cleaning and maintenance, thereby ensuring a high level of hygiene within the evaporator assembly (100).

[0066] Figure 11 and Figure 12 This is a front perspective view illustrating an embodiment of the evaporator assembly (100). Similar to the preferred embodiment described above, the evaporator assembly (100) herein also includes a first metal plate (1) and a second metal plate (2). The first metal plate (1) and the second metal plate (2) define a plurality of protrusions (1x and 2x) extending from a first main surface (19), wherein each of the plurality of protrusions (1x and 2x) may define a groove (S) in a corresponding second main surface (20) opposite to the first main surface (19) of the corresponding first metal plate (1) and the second metal plate (2). The first metal plate (1) and the second metal plate (2) have a similar structure as described above. Furthermore, a plurality of cutouts (16) may be etched into the internal sections of the first metal plate (1) and the second metal plate (2). Cutouts (16) etched in the first metal plate (1) and the second metal plate (2) can be constructed at the top of the V-shaped protrusions (1x and 2x) and along the ice-forming surface (Z) of the first metal plate (1) and the ice-forming surface (Z) of the second metal plate (2). Circular cutouts (16) can extend along the central region of the evaporator assembly (100), and cutouts (16) etched in the first metal plate (1) and the second metal plate (2) can be configured to compactly accommodate the refrigerant pipe (3).

[0067] The front end of the first metal plate (1) may be configured to define at least one first flange (17), and the second metal plate (2) may also be configured to define at least one second flange (18). The first flange (17) and the second flange (18) may be defined in a direction perpendicular to the ice-forming surface (Z). The first flange (17) and the second flange (18) may be integral parts of the first metal plate (1) and the second metal plate (2), respectively, and may be formed by stamping or deforming in a direction perpendicular to the ice-forming surface (Z). In this particular embodiment, the first flange (17) and the second flange (18) may each be configured as a single component extending through the height of the evaporator assembly (100). The first flange (17) may be configured to partially extend over the second flange (18) to define an intermediate section in which the first flange (17) and the second flange (18) contact each other. In one embodiment, the first flange (17) may extend on the second flange (18) such that an intermediate overlapping section may be defined along the center of the evaporator assembly (100). A first hole (5a) or opening may be defined on the intermediate overlapping section such that the first hole (5a) extends through the first flange (17), and the second flange (18) may define a second hole (5b) extending through the second flange (18). The first hole (5a) on the first flange (17) and the second hole (5b) on the second flange (18) may be configured to be oriented along the same axis when the first flange (17) and the second flange (18) are positioned adjacent to each other. The first hole (5a) on the first flange (17) and the second hole (5b) on the second flange (18) may receive a second fastener (5). The second fastener (5) can be fastened into the first hole (5a) of the first flange (17) and the second hole (5b) of the second flange (18), so that the first flange (17) is securely connected to the second flange (18). In addition, the second flange (18) can define a third hole (4a) extending through the second flange (18). The third hole (4a) can be configured to receive the first fastener (4).

[0068] Figure 13 This is a top view of an embodiment of the evaporator assembly (100), and Figure 14 It comes from Figure 13 An enlarged top view of the cross-section A of the evaporator. One or more slots (S) defined on the second main surface (20) of the first metal plate (1) accommodate a plurality of first connectors (6a), and one or more slots (S) defined on the second main surface (20) of the second metal plate (2) accommodate a plurality of second connectors (6b). The inner surfaces of each of the V-shaped first protrusion (1x) and second protrusion (2x) may be respectively provided with a plurality of first connectors (6a) and a plurality of second connectors (6b). As shown from... Figure 2As can be seen, each of the V-shaped first protrusions (1x) on the first metal plate (1) has a plurality of first connectors (6a) on its inner surface. The plurality of first connectors (6a) can extend through the length of each of the first protrusions (1x) on the first metal plate (1). Furthermore, the plurality of first connectors (6a) can be straight elongated members and can be tensioning members. The plurality of first connectors (6a) are constrained on a first locking bar (6y). Figure 17 [Clearly visible in the middle], and the first metal plate (1) extends through the length of the evaporator assembly (100). The first metal plate (1) can be constructed with a plurality of first locking bars (6y) having a plurality of first connectors (6a). The plurality of first connectors (6a) can be cut and formed to define elongated members acting as tension members. Similarly, a plurality of second connectors (6b) are provided on the inner surface of each of the V-shaped second protrusions (2x) on the second metal plate (2). The plurality of second connectors (6b) can be arranged through the length of each of the second protrusions (2x) of the second metal plate (2). Furthermore, the plurality of second connectors (6b) can be straight elongated members and can be tension members. The plurality of second connectors (6b) are defined on the second locking bars (6x) [from...] Figure 17 [Clearly visible in the image], and the second locking strip (6x) extends through the length of the evaporator assembly (100). Multiple second locking strips (6x) with multiple second connectors (6b) can be constructed for the second metal plate (2). The multiple second connectors (6b) can be cut and formed to define elongated members that function as tensioning members. Furthermore, during the assembly of the evaporator assembly (100), the first metal plate (1) slides relative to the second metal plate (2) in a first direction (X), such that the multiple first connectors (6a) and the multiple second connectors (6b) engage with each other to secure the first metal plate (1) and the second metal plate (2). The tension between the multiple first connectors (6a) and the multiple second connectors (6b) holds the first metal plate (1), the second metal plate (2), and the refrigerant pipe (3) together.

[0069] Figure 15 This is a top perspective view of an embodiment of an evaporator assembly (100) with multiple connectors (6a and 6b) in a first stage of disassembly, wherein the clamping screws have been removed. Figure 16 This is a top perspective view illustrating an embodiment of the evaporator assembly (100) in a disassembled state during the second stage of disassembly, wherein pull-out screws are tightened to separate the two plates (1 and 2), and Figure 17This is an exploded view of an embodiment of the evaporator assembly (100) after disassembly. The removal of the clamping screws and the tightening of the pull-out screws are similar to the process illustrated in the preferred embodiment described above.

[0070] Figure 18 and Figure 19 A side view and a perspective view of a vertical flow ice maker (101) having an evaporator assembly (100) are shown respectively. In embodiments of this disclosure, an evaporator assembly (100) and a fluid tank (14) may be provided in the ice maker (101). Ice blocks formed by the evaporator assembly (100) can slide by means of an ice chute (13) and can be obtained in a container (15) within the ice maker (101).

[0071] In embodiments of this disclosure, the configuration of the evaporator assembly (100) having connector (6), flanges (17 and 18), first fastener (4) and second fastener (5) makes it easy to assemble and disassemble the evaporator assembly (100) for regular cleaning and maintenance.

[0072] In embodiments of this disclosure, disassembling and cleaning the evaporator assembly (100) ensures and enables users to maintain a high standard of hygiene.

[0073] In embodiments of this disclosure, the overall heat transfer between the refrigerant pipe (3) and the fluid to be converted into ice is improved because the fluid is in direct contact with the refrigerant pipe (3).

[0074] In embodiments of this disclosure, the rate at which fluid is converted into ice is increased and ice blocks of the desired shape and size can be produced within a short time span.

[0075] In embodiments of this disclosure, the overall operating efficiency of the evaporator assembly (12) is improved by enabling ice to form directly on the refrigerant pipe (3).

[0076] In the embodiments of this disclosure, the above-described configuration of the first metal plate (1) and the second metal plate enables the incident angle (X) of the defrosting fluid to be equal to 20 degrees, thereby significantly improving the rate of ice collection.

[0077] In this embodiment, in the above configuration of the evaporator assembly (100), ice (11) is formed directly on the refrigerant pipe (3). Therefore, due to this configuration, the use of additional copper plates adjacent to the refrigerant pipe (3) used to form the ice can be avoided. Thus, the amount of copper used is minimized, and the overall manufacturing cost of the evaporator assembly (100) is economical. Furthermore, since the evaporator assembly (100) is configured to be removable by means of multiple first connectors (6a) and second connectors (6b), the above configuration of the evaporator assembly (100) allows for a reduction in the amount of tin used in manufacturing the evaporator assembly (100). In view of this, the problem of rusting of tin material is also mitigated, and higher hygiene standards can be achieved.
