Description

Technical Field

[0001] This invention relates to the field of ice maker technology, and more particularly to a spray component and an ice maker. Background Technology

[0002] Currently, ice makers in related technologies spray water into the ice grid through spray holes during ice making. However, during the spraying process, the water flow from the spray holes is usually in a single direction, resulting in a deep pit in the middle of the ice block after ice making, which affects the quality of ice making. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a spraying component that can significantly reduce the depth of the pit in the center region of ice blocks, thereby improving ice-making quality.

[0004] The present invention also proposes an ice maker.

[0005] According to a first aspect of the present invention, a spray member includes: ontology; A spray structure is provided on the main body. The spray structure includes a spray inlet, a spray outlet, a spray channel, a first deflection channel, and a second deflection channel. The spray channel is located between the spray inlet and the spray outlet. A first end of the spray channel is connected to the spray inlet, and a second end of the spray channel is connected to the spray outlet. Along a first direction, the first deflection channel and the second deflection channel are respectively located on both sides of the spray channel. One end of the first deflection channel is connected to the first end, and the other end of the first deflection channel is connected to the second end. One end of the second deflection channel is connected to the first end, and the other end of the second deflection channel is connected to the second end.

[0006] According to the spray component of the present invention, since the two ends of the first deflection channel are respectively connected to the first end and the second end of the spray channel, and the two ends of the second deflection channel are respectively connected to the first end and the second end of the spray channel, the water path between the spray inlet and the spray outlet is divided into three paths. Specifically, when making ice, water flows in from the spray inlet. Since the water flow in different paths is random and the force of the water flow in different paths is different (pressure, velocity, flow rate, kinetic energy), the water flow will switch left and right to spray out, so that the water flow sprayed from the spray outlet forms a diffused water curtain and oscillates left and right within a certain range, increasing the spray range. Compared with vertical spraying in a single direction, the impact force of the water flow can be reduced, thereby significantly reducing the depth of the pit in the center area of ​​the ice block and improving the ice-making quality.

[0007] According to an embodiment of the present invention, at least one of the first deflection channel and the second deflection channel comprises: The diversion section is connected to the first end; The deflection section is located on the side of the diversion section near the second end. One end of the deflection section is connected to the diversion section, and the other end of the deflection section extends toward the side where the spray channel is located and is connected to the second end.

[0008] In other words, after the water enters from the spray inlet, it is first diverted and randomly enters the first or second deflection channel. It then flows through the diversion section and the deflection section in sequence, and then converges at the second end of the spray channel. Finally, it is sprayed out through the spray outlet. The spray shape changes from left to right, which increases the spray range and reduces the impact force of the water flow, thereby effectively reducing the depth of the pit in the center of the ice block.

[0009] According to one embodiment of the present invention, the flow area of ​​the deflection section is smaller than the flow area of ​​the diversion section.

[0010] Because the deflection section is located near the second end of the spray channel, the flow area of ​​the deflection section is set to be relatively small. When the water flows from the diversion section into the deflection section, it can pressurize the water flow, so that the water flow sprayed from the spray outlet can reach the spray height, ensuring that the water flow can enter the ice grid assembly for ice making.

[0011] According to one embodiment of the present invention, the diversion section includes: The first segment is connected to the first end; The second segment is located between the first segment and the deflection segment, with one end of the second segment connected to the first segment and the other end of the second segment connected to the deflection segment; The circulation area of ​​the second segment is smaller than that of the first segment.

[0012] Because the flow area of ​​the second section is smaller than that of the first section, the water flow can be pressurized during the flow of the first or second deflection channel, so that the water flow from the spray outlet can reach the spray height and ensure that the water flow can enter the ice grid assembly for ice making.

[0013] According to one embodiment of the present invention, the flow area of ​​the spray outlet is S, wherein 4mm 2 ≤S≤7mm 2 .

[0014] By limiting the flow area of ​​the spray outlet to 4mm 2 Up to 7mm 2 This design ensures that the water jet from the spray nozzles reaches the required height while reducing the depth of the pit in the center of the ice block, thus ensuring ice-making quality.

[0015] According to one embodiment of the present invention, the flow area of ​​the spray outlet near the spray channel is smaller than the flow area of ​​the spray outlet away from the spray channel.

[0016] In other words, the opening area of ​​the spray outlet is smaller at the end near the spray channel and larger at the end away from the spray channel, thus forming an flared structure from the inside out. This increases the spray range of the water jet from the spray outlet, making the water flow into a diffused water curtain, and oscillating back and forth within a certain range, reducing the impact force of the water flow, and thus reducing the depth of the pit in the center of the ice block.

[0017] According to one embodiment of the present invention, the flow area of ​​the spray inlet at the end near the spray channel is smaller than the flow area of ​​the spray inlet at the end away from the spray channel.

[0018] In other words, the opening area of ​​the spray inlet is smaller at the end near the spray channel and larger at the end away from the spray channel, thus forming an flared structure from the inside out. This can pressurize the water flow entering the spray inlet, allowing the water flow from the spray outlet to reach the spray height.

[0019] According to one embodiment of the present invention, the flow area of ​​the first end is smaller than the flow area of ​​the second end.

[0020] In other words, the channel wall of the spray channel extends from the inside out and forms a flared structure, which can guide the water flow into the spray channel, ensure the amount of water sprayed out, and help shorten the ice-making time and improve the ice-making efficiency.

[0021] According to one embodiment of the present invention, the body further includes a water storage chamber, the water storage chamber being connected to the spray inlet, and the spray element further includes: A connector is provided on the body and located outside the water storage cavity. The connector has a water inlet that communicates with the water storage cavity.

[0022] Because the water flows into the water storage chamber before entering the spray nozzle, it can buffer the water flow, reduce the flow velocity, and thus reduce the kinetic energy of the water flow, so that the mist water flow sprayed from the spray nozzle has sufficient pressure to ensure the spray height.

[0023] According to one embodiment of the present invention, the spray element further includes: A buffer pipe is provided inside the water storage chamber and connected to the water inlet. The buffer pipe has a buffer port on the side away from the spray channel, and the buffer pipe is connected to the water storage chamber through the buffer port.

[0024] This extends the water flow path, effectively buffering the water flow, reducing its velocity and kinetic energy, and ensuring sufficient pressure for the mist-like water jet from the spray nozzle to maintain the spray height.

[0025] An ice maker according to a second aspect of the present invention includes a spray component as described in the first aspect of the present invention; a body having a water storage chamber connected to the spray inlet. An ice-making module is located on the machine body. The ice-making module includes an ice tray assembly and an evaporator. The ice tray assembly is located on the top of the spray component and is positioned opposite to the spray outlet. The evaporator is located on the side of the ice tray assembly away from the spray component.

[0026] According to an embodiment of the ice maker of the present invention, specifically, during ice making, the water in the water storage chamber flows towards the spray inlet. After entering the spray inlet, it is divided by the spray channel, the first deflection channel, and the second deflection channel, and finally converges at the top and is sprayed out through the spray outlet. Because the water flow in different water channels is random and the forces of the water flow in different water channels are different (e.g., pressure, velocity, flow rate, kinetic energy), the water flow will switch left and right to spray out, thereby making the water flow sprayed from the spray outlet into a diffused water curtain, and oscillating left and right within a certain range, increasing the spray range and reducing the impact force of the water flow. The sprayed mist-like water flow enters the ice grid assembly and makes ice under the action of the evaporator. After ice making is completed, the ice blocks fall and detach, reducing the depth of the pit in the center area of ​​the ice blocks.

[0027] According to one embodiment of the present invention, the ice maker further includes: A water supply pipe is connected to a connector of the spray unit; A pump body is disposed on the machine body and connected to the water supply pipe. The pump body includes an inlet, which is connected to the water storage chamber. A filter screen is provided at the inlet; The filter screen includes multiple openings, and the flow area of ​​any one of the openings is smaller than the flow area of ​​the spray inlet.

[0028] By installing a filter screen at the pump inlet, the water in the water storage chamber can be filtered, preventing impurities in the water storage chamber from clogging the pump body, water supply pipe, or spray inlet, thus ensuring the reliability and stability of the ice maker's operation.

[0029] Since the flow area of ​​any opening in the filter screen is smaller than that of the spray inlet, it can effectively prevent impurities in the water storage chamber from clogging the spray inlet, ensuring that water can be smoothly discharged from the spray outlet for spraying and ice making.

[0030] According to one embodiment of the present invention, the ice maker further includes: A temperature sensing element is installed at the outlet of the evaporator to detect the outlet temperature of the evaporator.

[0031] Understandably, if ice blocks are not completely detached during an ice-making cycle, large chunks of ice will form in the next cycle, ultimately preventing the ice maker from properly detaching ice and rendering it inoperable. By installing a temperature sensor at the evaporator outlet, the evaporator outlet temperature will be abnormally low when detachment is abnormal. In this case, the ice-making system will directly execute an anti-large ice program until the remaining ice blocks melt and fall off.

[0032] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: Since the two ends of the first deflection channel are connected to the first and second ends of the spray channel, respectively, and the two ends of the second deflection channel are also connected to the first and second ends of the spray channel, the water path between the spray inlet and the spray outlet is divided into three paths. Specifically, when making ice, the water flows in from the spray inlet. Because the water flow in different paths is random and the forces (pressure, velocity, flow rate, kinetic energy) of the water flow in different paths are different, the water flow will switch left and right to spray out, so that the water flow sprayed from the spray outlet forms a diffused water curtain and oscillates left and right within a certain range, increasing the spray range. Compared with vertical spray in a single direction, it can reduce the impact force of the water flow, thereby significantly reducing the depth of the pit in the center area of ​​the ice block and improving the ice-making quality.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0051] The following is combined with Figures 1 to 10 The spray component 1 and ice maker 9 provided in the embodiments of the present invention will be described in detail through specific embodiments and application scenarios.

[0052] Firstly, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment of the invention provides a spray component 1, which includes a body 10 and a spray structure 18. The spray structure 18 is disposed on the body 10. The spray structure 18 includes a spray inlet 12, a spray outlet 14, a spray channel 20, a first deflection channel 30, and a second deflection channel 40. The spray channel 20 is disposed between the spray inlet 12 and the spray outlet 14. The first end 22 of the spray channel 20 is connected to the spray inlet 12, and the second end 24 of the spray channel 20 is connected to the spray outlet 14. Along a first direction, the first deflection channel 30 and the second deflection channel 40 are respectively disposed on both sides of the spray channel 20. One end of the first deflection channel 30 is connected to the first end 22, and the other end of the first deflection channel 30 is connected to the second end 24. One end of the second deflection channel 40 is connected to the first end 22, and the other end of the second deflection channel 40 is connected to the second end 24.

[0053] The spray component 1 provided in this embodiment of the invention includes a body 10 and a spray structure 18. Specifically, the spray structure 18 includes a spray inlet 12, a spray outlet 14, a spray channel 20, a first deflection channel 30, and a second deflection channel 40. Along a first direction, the first deflection channel 30 and the second deflection channel 40 are located on opposite sides of the spray channel 20, that is, the first deflection channel 30 and the second deflection channel 40 are located on the left and right sides of the spray channel 20, respectively. Optionally, the first deflection channel 30 is located on the left side of the spray channel 20, and the second deflection channel 40 is located on the right side of the spray channel 20. Alternatively, the first deflection channel 30 is located on the right side of the spray channel 20, and the second deflection channel 40 is located on the left side of the spray channel 20. The specific configuration can be adjusted according to actual needs.

[0054] Since the two ends of the first deflection channel 30 are connected to the first end 22 and the second end 24 of the spray channel 20, respectively, and the two ends of the second deflection channel 40 are connected to the first end 22 and the second end 24 of the spray channel 20, the water path between the spray inlet 12 and the spray outlet 14 is divided into three paths. Specifically, when making ice, the water flows in from the spray inlet 12. Since the water flow in different paths is random and the force of the water flow in different paths is different (e.g., pressure, velocity, flow rate, kinetic energy), the water flow will switch left and right to spray out, so that the water flow sprayed from the spray outlet 14 is a diffused water curtain, and it oscillates left and right within a certain range, increasing the spray range. Compared with vertical spray in a single direction, it can reduce the impact force of the water flow, thereby significantly reducing the depth of the pit in the center area of ​​the ice block and improving the ice-making quality.

[0055] Optionally, the spray outlet 14 has a rectangular cross-sectional shape.

[0056] Optionally, the number of spray structures 18 can be multiple, and the specific number can be arranged according to the number of ice grids.

[0057] In some embodiments, such as Figure 2 As shown, at least one of the first deflection channel 30 and the second deflection channel 40 includes a diversion section 50 and a deflection section 60. The diversion section 50 is connected to the first end 22. The deflection section 60 is located on the side of the diversion section 50 closer to the second end 24. One end of the deflection section 60 is connected to the diversion section 50, and the other end of the deflection section 60 extends toward the side where the spray channel 20 is located and is connected to the second end 24.

[0058] In this embodiment, at least one of the first deflection channel 30 and the second deflection channel 40 is defined as including a diversion section 50 and a deflection section 60. Specifically, one end of the diversion section 50 is connected to the first end 22 of the spray channel 20, and the other end of the diversion section 50 is connected to the deflection section 60. The deflection section 60 extends to the side where the spray channel 20 is located and is connected to the second end 24 of the spray channel 20. That is, after the water flows in from the spray inlet 12, it is first diverted and randomly enters the first deflection channel 30 or the second deflection channel 40. It then flows through the diversion section 50 and the deflection section 60 in sequence, and then converges at the second end 24 of the spray channel 20. Finally, it is sprayed out through the spray outlet 14. The spray with the shape switching left and right increases the spray range and reduces the impact force of the water flow, thereby effectively reducing the depth of the pit in the center area of ​​the ice block.

[0059] In some embodiments, the flow area of ​​the deflection section 60 is smaller than the flow area of ​​the diversion section 50.

[0060] In this embodiment, since the deflection section 60 is close to the second end 24 of the spray channel 20, the flow area of ​​the deflection section 60 is set to be small. When the water flows from the diversion section 50 into the deflection section 60, it can pressurize the water flow, so that the water flow sprayed from the spray outlet 14 can reach the spray height, ensuring that the water flow can enter the ice grid assembly 110 for ice making.

[0061] In some embodiments, such as Figure 2 As shown, the diversion section 50 includes a first section 52 and a second section 54. The first section 52 is connected to the first end 22. The second section 54 is located between the first section 52 and the deflection section 60, with one end of the second section 54 connected to the first section 52 and the other end of the second section 54 connected to the deflection section 60. The flow area of ​​the second section 54 is smaller than that of the first section 52.

[0062] In this embodiment, the diversion section 50 is defined as including a first section 52 and a second section 54. Specifically, the first section 52 is connected to the first end 22 of the spray channel 20, and the second section 54 is located between the first section 52 and the deflection section 60. That is, after the water flows in from the spray inlet 12, it is first diverted and randomly enters the first deflection channel 30 or the second deflection channel 40. It then flows through the first section 52, the second section 54 and the deflection section 60 in sequence, and then converges at the second end 24 of the spray channel 20. Finally, it is sprayed out through the spray outlet 14. The spray shape changes from left to right, which increases the spray range and reduces the impact force of the water flow, thereby effectively reducing the depth of the pit in the center area of ​​the ice block.

[0063] Since the flow area of ​​the second section 54 is smaller than that of the first section 52, the water flow can be pressurized during the flow of the first deflection channel 30 or the second deflection channel 40, so that the water flow sprayed from the spray outlet 14 can reach the spray height and ensure that the water flow can enter the ice grid assembly 110 for ice making.

[0064] In some embodiments, the flow area of ​​the spray outlet 14 is S, where 4mm 2 ≤S≤7mm 2 .

[0065] In this embodiment, the range of values ​​for the flow area of ​​the spray outlet 14 is defined. Specifically, the flow area of ​​the spray outlet 14 is within 4 mm. 2 Up to 7mm 2 Between. It is understandable that if the flow area of ​​the spray outlet 14 is too small, i.e. less than 4mm... 2 If the water pressure from the spray outlet 14 is too high, the resulting ice blocks will have deep pits, affecting the ice-making effect. If the flow area of ​​the spray outlet 14 is too large, i.e., greater than 7mm... 2 If the pressure of the water jet from the spray outlet 14 is too low, it cannot reach the required spray height, and therefore cannot enter the ice grid assembly 110 to make ice.

[0066] By limiting the flow area of ​​the spray outlet 14 to 4 mm 2 Up to 7mm 2 In between, it can ensure that the water flow from the self-spraying outlet 14 can smoothly reach the required height while reducing the depth of the pit in the center of the ice block, thus ensuring the quality of ice making.

[0067] Optionally, the flow area of ​​the spray outlet 14 is 4 mm. 2 5mm 2 6mm 2 and 7mm 2 Any one of them.

[0068] In some embodiments, the flow area of ​​the spray outlet 14 near the spray channel 20 is smaller than the flow area of ​​the spray outlet 14 away from the spray channel 20.

[0069] In this embodiment, since the flow area of ​​the end of the spray outlet 14 near the spray channel 20 is smaller than the flow area of ​​the end of the spray outlet 14 away from the spray channel 20, that is, the opening area of ​​the spray outlet 14 near the spray channel 20 is smaller and the opening area of ​​the end away from the spray channel 20 is larger, the spray outlet 14 is formed into an flared structure from the inside to the outside, which can increase the spray range of the water flow from the spray outlet 14, so that the water flow is a diffused water curtain, and oscillates back and forth within a certain range, reducing the impact force of the water flow, and thus reducing the depth of the pit in the center area of ​​the ice block.

[0070] In some embodiments, the flow area of ​​the spray inlet 12 near the spray channel 20 is smaller than the flow area of ​​the spray inlet 12 away from the spray channel 20.

[0071] In this embodiment, since the flow area of ​​the end of the spray inlet 12 near the spray channel 20 is smaller than the flow area of ​​the end of the spray inlet 12 away from the spray channel 20, that is, the opening area of ​​the spray inlet 12 near the spray channel 20 is smaller and the opening area of ​​the end away from the spray channel 20 is larger, the spray inlet 12 is formed into an flared structure from the inside to the outside, which can pressurize the water flow entering the spray inlet 12, so that the water flow sprayed from the spray outlet 14 can reach the spray height.

[0072] In some embodiments, the flow area of ​​the first end 22 is smaller than the flow area of ​​the second end 24.

[0073] In this embodiment, since the flow area of ​​the first end 22 of the spray channel 20 is small and the flow area of ​​the second end 24 is large, that is, the channel wall of the spray channel 20 extends from the inside to the outside and forms a flared structure, which can guide the water flow entering the spray channel 20, ensure the amount of water sprayed out, and help shorten the ice-making time and improve the ice-making efficiency.

[0074] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the main body 10 also has a water storage chamber 16, which is connected to the spray inlet 12. The spray component 1 also includes a connector 70, which is located on the main body 10 and outside the water storage chamber 16. The connector 70 has a water inlet 72, which is connected to the water storage chamber 16.

[0075] In this embodiment, the spray component 1 is further defined as including a connector 70. Specifically, the connector 70 includes a water inlet 72, which is connected to a water storage chamber 16, and the water storage chamber 16 is connected to a spray inlet 12. Specifically, when making ice, the water flow first enters the water storage chamber 16 through the water inlet 72, then enters the spray inlet 12, and after being split by the spray channel 20, the first deflection channel 30, and the second deflection channel 40, it converges at the top and finally sprays out through the channel spray outlet 14.

[0076] Because the water flows into the water storage chamber 16 before entering the spray inlet 12, it can buffer the water flow, reduce the flow velocity, and thus reduce the kinetic energy of the water flow, so that the mist water flow sprayed from the spray outlet 14 has sufficient pressure to ensure the spray height.

[0077] Optionally, the body 10 and the connector 70 are integrated into one structure, which helps to improve the connection strength between the body 10 and the connector 70, reduce the number of parts, and also helps to improve the overall sealing of the spray component 1, ensuring the ice-making quality.

[0078] Optionally, the water inlet 72 is connected to the water storage chamber 92 of the ice maker 9.

[0079] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the spray unit 1 also includes a buffer pipe 80, which is located in the water storage chamber 16 and connected to the water inlet 72. The buffer pipe 80 has a buffer port 82 on the side away from the spray channel 20, and the buffer pipe 80 is connected to the water storage chamber 16 through the buffer port 82.

[0080] In this embodiment, the spray component 1 is further defined as including a buffer pipe 80. Specifically, the buffer pipe 80 is located inside the water storage chamber 16 and is connected to the water inlet 72.

[0081] A buffer port 82 is provided on the side of the buffer pipe 80 away from the spray channel 20, that is, the buffer port 82 is provided at the bottom of the buffer pipe 80, and the buffer port 82 is connected to the water storage chamber 16. In other words, when making ice, the water first enters the buffer pipe 80 through the inlet 72, and then flows into the water storage chamber 16 through the buffer port 82 at the bottom of the buffer pipe 80. Then it flows upward into the spray inlet 12, and after being divided by the spray channel 20, the first deflection channel 30 and the second deflection channel 40, it converges at the top and finally sprays out from the channel spray outlet 14.

[0082] This extends the water flow path, effectively buffering the water flow, reducing its velocity and kinetic energy, and ensuring sufficient pressure for the mist-like water jet from the spray outlet 14 to guarantee the spray height.

[0083] Optionally, the wall of the water storage chamber 16 includes a backflow slope, which is disposed opposite to the spray inlet 12. At least a portion of the backflow slope is inclined toward the side where the connector 70 is located, and water on the backflow slope can flow into the inlet 72.

[0084] After ice making is completed, the residual water in the water storage chamber 16 can be guided by the return slope and flow back to the water storage chamber 92 through the water inlet 72, the water supply pipe 140 and the pump body 150. This not only avoids the growth of bacteria in the water storage chamber 16 due to the presence of a lot of residual water, but also enables the recycling of water, which is beneficial for water conservation.

[0085] Optionally, the angle between the return slope and the horizontal plane is α, where α ≥ 2°.

[0086] By setting the inclination angle of the return slope to be greater than or equal to 2°, the residual water in the water storage chamber 16 can flow along the inclination trend of the return slope and be discharged in a timely manner, thereby reducing the growth of bacteria in the water storage chamber 16.

[0087] Secondly, such as Figure 6 and Figure 8 As shown, this embodiment of the invention provides an ice maker 9, which includes a spray element 1, a body 90, and an ice-making module 100 as described in the first aspect embodiment above. The body 90 has a water storage chamber 92, which communicates with the spray inlet 12. The ice-making module 100 is disposed on the body 90. The ice-making module 100 includes an ice tray assembly 110 and an evaporator 120. The ice tray assembly 110 is disposed on the top of the spray element 1 and is disposed opposite to the spray outlet 14. The evaporator 120 is disposed on the side of the ice tray assembly 110 away from the spray element 1.

[0088] Since the ice maker 9 provided in this embodiment includes the spray component 1 as provided in the first aspect embodiment above, it has all the beneficial technical effects of the spray, which will not be described again here.

[0089] The ice maker 9 provided in this embodiment of the invention includes a spray component 1, a body 90 and an ice-making module 100. Specifically, the ice-making module 100 includes an ice tray assembly 110 and an evaporator 120. The ice tray assembly 110 is located on top of the spray component 1 and is disposed opposite to the spray outlet 14.

[0090] Specifically, during ice making, the water in the water storage chamber 92 flows towards the spray inlet 12. After entering the spray inlet 12, it is divided by the spray channel 20, the first deflection channel 30, and the second deflection channel 40. Finally, after converging at the top, it is sprayed out through the spray outlet 14. Because the water flow in different water channels is random and the force of the water flow in different water channels is different (e.g., pressure, velocity, flow rate, kinetic energy), the water flow will switch left and right to spray out, so that the water flow sprayed from the spray outlet 14 forms a diffused water curtain and oscillates left and right within a certain range, increasing the spray range and reducing the impact force of the water flow. The sprayed mist-like water flow enters the ice grid assembly 110 and is iced under the action of the evaporator 120. After ice making is completed, the ice blocks fall and detach, reducing the depth of the pit in the center area of ​​the ice blocks.

[0091] Optionally, the ice tray assembly 110 includes multiple ice trays, each of which is opposite to a multiple spray outlet 14. The shape of each ice tray can be set according to actual needs, including but not limited to circular, square, rectangular, triangular or oval shapes.

[0092] Optionally, the ice-making module 100 also includes a compressor 130.

[0093] In some embodiments, such as Figure 7 and Figure 8 As shown, the ice maker 9 also includes a water supply pipe 140, a pump body 150, and a filter screen 160. The water supply pipe 140 is connected to the connector 70 of the spray unit 1. The pump body 150 is located on the machine body 90 and is connected to the water supply pipe 140. The pump body 150 includes an inlet 152, which communicates with the water storage chamber 92. The filter screen 160 is located at the inlet 152. The filter screen 160 includes multiple mesh openings, and the flow area of ​​any mesh opening is smaller than the flow area of ​​the spray inlet 12.

[0094] In this embodiment, the ice maker 9 further includes a water supply pipe 140, a pump body 150, and a filter screen 160. Specifically, the two ends of the water supply pipe 140 are connected to the pump body 150 and the connector 70 of the spray element 1, respectively. The pump body 150 is mounted on the machine body 90. During ice making, the pump body 150 starts working, drawing water from the water storage chamber 92 into the water storage chamber 92.

[0095] By installing a filter screen 160 at the inlet 152 of the pump body 150, the water in the water storage chamber 92 can be filtered to prevent impurities in the water storage chamber 92 from clogging the pump body 150, the water supply pipe 140, or the spray inlet 12, thus ensuring the reliability and stability of the ice maker 9.

[0096] Since the flow area of ​​any opening of the filter screen 160 is smaller than the flow area of ​​the spray inlet 12, it can effectively prevent impurities in the water storage chamber 92 from clogging the spray inlet 12, ensuring that the spray outlet 14 can smoothly discharge water for spraying and ice making.

[0097] In some embodiments, the ice maker 9 further includes a temperature sensing element disposed at the outlet of the evaporator 120 for detecting the outlet temperature of the evaporator 120.

[0098] In this embodiment, the ice maker 9 is further defined as including a temperature detection element, specifically, the temperature detection element is located at the outlet of the evaporator 120. It is understood that if ice is not completely detached during an ice-making cycle, large blocks of ice will form in the next ice-making cycle, ultimately causing the ice maker 9 to fail to detach ice properly and lose its ice-making function. By installing a temperature detection element at the outlet of the evaporator 120, when detachment is abnormal, the outlet temperature of the evaporator 120 will be abnormally low. At this time, the ice-making system directly executes an anti-large ice program until the remaining ice melts and falls off.

[0099] Optionally, the anti-icing procedure can be an immediate de-icing procedure.

[0100] Optionally, the temperature sensing element can be a temperature probe.

[0101] Optionally, the spray component 1 is made of PP plastic material, with a processing accuracy of ±0.1mm, a temperature resistance of -20~50℃, and resistance to acid and alkali corrosion.

[0102] Optionally, such as Figure 8 , Figure 9 and Figure 10 As shown, the ice maker 9 also includes a partition 170, which is located on the side of the ice tray assembly 110 away from the evaporator 120. The partition 170 has a communication port that communicates with the opening of the ice tray.

[0103] In this embodiment, it is understood that the ice tray assembly 110 is usually a metal part, such as an aluminum structural part. During the circulating water spraying process, the water will directly contact the bottom surface of the ice tray assembly 110 and freeze. As a result, after the ice making is completed, the ice blocks in multiple ice trays stick together and cannot be separated, making it difficult to remove the ice and affecting the user experience.

[0104] By installing a partition 170 below the ice tray assembly 110, the circulating water is separated from the bottom surface of the ice tray assembly 110. During ice making, this effectively solves the problem of ice cubes sticking together in multiple ice trays due to the circulating water directly contacting the bottom surface of the ice tray assembly 110 and freezing. It also facilitates quick and easy ice removal after ice making, thus shortening the ice making time. Furthermore, after ice removal, the ice cubes are clearly separated, making it easier for users to remove ice and improving the user experience.

[0105] Optionally, partition 170 includes plastic components.

[0106] Understandably, plastic parts have a low thermal conductivity. In other words, installing plastic parts with low thermal conductivity under the ice tray assembly 110 prevents water from contacting the metal surface of the ice tray assembly 110 during the circulating water spraying process and freezing, which would eventually cause multiple ice cubes to stick together and become inseparable, thus ensuring that the produced ice cubes are distinct.

[0107] Optionally, the ice maker 9 also includes a water receiving box 190, which has a communicating water receiving chamber and an ice removal port. The spray nozzle 1 is disposed in the water receiving chamber, which is used to collect the water falling from the spray nozzle. After ice making is completed, the ice blocks enter the ice storage chamber 180 through the ice removal port.

[0108] Optionally, such as Figure 9 and Figure 10 As shown, the partition 170 includes a plate body 172 and a baffle 174. The plate body 172 is connected to the side of the ice grid assembly 110 away from the evaporator 120, and the plate body 172 has a communication opening. The baffle 174 is located on the side of the plate body 172 near the de-icing opening. During the spray ice-making process, as the ice freezes, the depth of the pit becomes shallower, but the flow rate of the spray water remains constant, resulting in a large amount of water splashing outwards along the perimeter of the pit. By setting the baffle 174, the outward splashing water flow can be blocked, thereby limiting the splashing direction of the water flow and reducing the risk of the ice in the ice storage chamber 180 melting due to the spray water splashing into the ice storage chamber 180.

[0109] Optionally, at least a portion of the baffle 174 is arc-shaped, and the end of the baffle 174 away from the plate body 172 bends inward to further restrict the water flow and prevent spray water from splashing into the ice storage chamber 180.

[0110] Optionally, such as Figure 10 As shown, the baffle 170 also includes multiple guide columns 176, which are spaced apart and arranged inside the baffle 174. Because water splashing is very severe in the latter half of ice making, a water curtain will form on the baffle 174. When the water curtain converges at a certain point and falls, a large volume of water will drop into the ice storage chamber 180. By setting multiple guide columns 176, the water flow is prevented from connecting horizontally to form a water curtain. Furthermore, the guide columns 176 have downward protrusions, which further facilitate the downward flow of water.

[0111] Optionally, such as Figure 10As shown, the partition 170 also includes an extension plate 178. Along the length of the plate body 172, the extension plate 178 is disposed on at least one side of the plate body 172, and extends along the length of the plate body 172 and toward the side away from the plate body 172. During ice making, the water flows upward along the wall due to the Coanda effect. At this time, there is only a thin layer of plastic (plate body 172) between the water flow and the metal ice grid assembly 110, resulting in poor heat insulation. This leads to ice formation on the sides, ultimately causing the ice to stick to the partition 170 for too large an area, making it difficult to remove the ice.

[0112] By providing an extension plate 178 on at least one side of the plate body 172 along its length, water flow is prevented from flowing upwards along the wall due to the Coanda effect, thus preventing difficulties in ice removal due to side icing, ensuring smooth ice removal, and helping to shorten ice-making time and improve ice-making efficiency.
