Description

Technical Field

[0001] The invention belongs to the technical field of ice making machines, and in particular relates to a household combined multifunctional ice making machine. Background Art

[0002] At present, ice cubes have become an auxiliary material in life, and miniaturized ice-making devices have gradually entered households. Especially in the hot summer, people can make ice conveniently while sitting at home and enjoy the cool taste brought by ice cubes to drinks and beer.

[0003] With the growing demand for product diversification and personalization among consumer groups, especially in scenarios where there are children in the family, in addition to conventional needs, users hope to make diversified ice cubes through DIY methods to enhance the user experience and the fun of the product. In the prior art, most household ice makers on the market only have a single ice-making system, and can usually only make ice cubes of standard shapes by using pure water, which cannot meet the personalized needs of users for ice cubes of different shapes and flavors. In addition, traditional ice makers use a flip motor to drive the water box to flip when defrosting. First, the water is drained and the ice cubes fall into a space for temporary storage, and then the shovel on the flip water box is used to push the ice cubes out of this space and make them fall into the ice storage room. The working mode of this ice maker has slow drainage and low defrosting efficiency, thereby reducing the ice making efficiency. Summary of the invention

[0004] The object of the present invention is to provide a household combined multifunctional ice maker to solve the problems of single ice making function, ice making efficiency and ice removing efficiency in the prior art.

[0018] The technical solution of the present invention has the following beneficial effects:

[0019] 1. The ice-making pump extracts water from the inside of the box and sends the water into the U-shaped tube through the second output pipe. The water is diverted by the U-shaped tube to the evaporators at both ends. The evaporators at both ends start making ice at the same time, which increases the ice-making speed. The diversion holes, heat conducting plates, water inlet grooves, and water outlets are all distributed on both sides, so that the water flow can start making ice at the same time on the heat conducting plates on both sides, further improving the ice-making efficiency; therefore, the evaporators set on both sides can make four groups of ice at the same time.

[0043] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] Embodiment 1:

[0045] refer to Figure 1-Figure 6 A household combined multifunctional ice maker comprises a box body 10 and a base 103. A waste water tank 13 is installed at the lower left of the box body 10. A water pump 16, a compressor 22, a condenser 23, a first ice making valve 24, a second ice making valve 25, and an ice-removing valve 26 are installed on the base 103. The water pump 16 is on the left side of the compressor 22, and the condenser 23 is on the right side of the compressor 22. A raw water tank 14 is arranged above the condenser 23. The output end and input end of the water pump 16 are respectively connected to a first output pipe 17 and an input pipe 18. One end of the input pipe 18 is connected to the lower part of the raw water tank 14, and one end of the first output pipe 17 is connected to the box body 10.

[0046] An ice pump 15 and a wastewater pump 20 are installed at the bottom of the box 10. A third output pipe 21 is installed at the output end of the wastewater pump 20. The third output pipe 21 is connected to the wastewater tank 13. A second output pipe 19 is installed at the output end of the ice pump 15. The second output pipe 19 extends to the inside of the box 10. One end of the second output pipe 19 is connected to a U-shaped pipe 41. Evaporators 40 are installed at both ends of the U-shaped pipe 41. A pad 102 is installed on the upper right side of the box 10, and a DIY ice making group is installed on the pad 102.

[0047] In the water circulation process of the ice maker in the above scheme, the raw water tank 14 stores water for making ice. When the ice maker is working, the water in the raw water tank 14 is firstly extracted by the water pump 16 through the input pipe 18, and the water is transported to the inside of the box body 10 through the first output pipe 17. There is a water level float in the box body 10 (not clearly indicated in the figure), and the float senses and controls the start and stop of the water pump 16. When the water in the box body 10 reaches a certain height, the water pump 16 stops pumping water; then the ice making pump 15 extracts the water in the box body 10, and sends the water into the U-shaped tube 41 through the second output pipe 19, and the water is diverted by the U-shaped tube 41 to the evaporators 40 at both ends. The evaporators 40 at both ends start to make ice at the same time, thereby increasing the ice making speed. When the ice maker is used for a long time, scale will be present inside. After flushing and cleaning the inside of the box body 10, the waste water pump 20 is started to pump the water used for cleaning the inside of the box body 10 into the waste water tank 13 through the third output pipe 21. It is worth noting that: the waste water tank 13 is detachable to facilitate dumping of the water inside the waste water tank 13; or a pump body is installed on the waste water tank 13 to pump the water inside the waste water tank 13 to the sewer for discharge.

[0048] refer to Figure 1-Figure 6 and Fig.15 The first ice-making valve 24 is connected to a capillary tube 27 , the capillary tube 27 on the first ice-making valve 24 is connected to the evaporator 40 , and the second ice-making valve 25 is connected to the DIY ice-making group through the capillary tube 27 .

[0049] The working process of compressor 22 making ice: after compressor 22 works, high-temperature and high-pressure gas is compressed by compressor 22, and after heat exchange in condenser 23, it becomes low-temperature and high-pressure liquid, and after residual moisture is filtered out by drying filter, the first ice-making valve 24 is normally opened, and after throttling through capillary 27, a high-pressure liquid is formed in evaporator 40, and the pressure is instantly lost to form low-temperature gas for ice-making and heat exchange; after heat exchange is completed, air is sucked by compressor 22, forming a reciprocating cycle working state. When the user wants to enable the DIY ice-making group to make DIY ice, the first ice-making valve 24 is closed, and the second ice-making valve 25 is opened. After the low-temperature and high-pressure liquid passes through capillary 27 and throttling, a high-pressure liquid is formed in the DIY ice-making group, and the pressure is instantly lost to form low-temperature gas for ice-making and heat exchange, and after heat exchange is completed, air is sucked by the compressor, forming a reciprocating cycle working state.

[0050] Deicing process: Deicing valve 26 opens, capillary 27 forms a pressure barrier, so the high-temperature and high-pressure gas pressed out by compressor 22 will flow to deicing valve 26 and enter evaporator 40 or DIY ice making group to melt ice cubes and form deicing. (Note: ice making and deicing by compressor 22 is an existing technical solution).

[0051] Further references Figure 7 A downwardly recessed collecting tank 11 is provided at the bottom of the box body 10 , and an ice-making pump 15 and a wastewater pump 20 are installed below the collecting tank 11 .

[0052] In a further embodiment, the water inside the box 10 quickly gathers on the collection tank 11. The rapid gathering property helps to reduce the retention time of water on the inner wall of the box 10, and the two ends above the collection tank 11 are inclined, which can further improve the water gathering effect and facilitate the ice pump 15 and the wastewater pump 20 to pump water. The ice pump 15 can directly extract clean water from the collection tank 11 to make ice, and the wastewater pump 20 can extract and discharge the treated wastewater from the collection tank 11. This layout reduces the resistance of water flow and improves the working efficiency of the pump.

[0053] refer to Figure 10-13The evaporator 40 includes a water distribution trough 42, which is connected to the U-shaped tube 41. A plurality of diversion holes 421 are evenly distributed at the bottom of the water distribution trough 42. A diversion trough 43 is provided below the water distribution trough 42. Water outlets 431 are provided at both ends of the diversion trough 43. A cold pipe 44 is installed below the diversion trough 43. The cold pipe 44 is in a U-shaped structure. The capillary 27 is connected to the cold pipe 44. Heat conducting plates 45 are provided on both sides of the cold pipe 44. A guide block 47 is installed at the bottom of the heat conducting plate 45. Water inlet grooves 471 are symmetrically provided on both sides of the guide block 47. A water guide groove 48 is installed below the guide block 47. The deicing valve 26 is connected to the cold pipe 44 through a pipeline; when the deicing valve 26 is opened, the capillary 27 forms a pressure barrier, so the high-temperature and high-pressure gas pressed out by the compressor 22 will flow into the cold pipe 44 in the direction of the deicing valve 26 to complete deicing.

[0054] In the above scheme, the ice pump 15 continuously extracts water from the inside of the box 10, and the water is diverted by the U-shaped tube 41 to the water distribution grooves 42 at both ends. The water fills the water distribution grooves 42, and is discharged from the diversion hole 421 into the diversion groove 43. The water flows downward from the water outlet 431, and the water is evenly in contact with the surface of the heat conducting plate 45; the low-temperature and high-pressure liquid enters the cold pipe 44 through the capillary 27, and the heat conducting plates 45 on both sides of the cold pipe 44 absorb the heat of the cold pipe 44, so that ice cubes gradually solidify on the surface of the heat conducting plate 45 to form ice cubes; The flowing unsolidified water flows along the heat conducting sheet 45 to the water inlet groove 471 and then enters the water guide groove 48. The water guide groove 48 discharges the unsolidified water back into the box 10, thereby forming a reciprocating cycle of the waterway. The circulation mechanism ensures the full utilization of water resources and also helps to maintain the low temperature state of the water in the box 10. The reciprocating water will become cold water, which will be pumped by the ice making pump 15 again and enter the evaporator 40, greatly reducing the working energy consumption of the compressor 22. Since the diverter hole 421, the heat conducting sheet 45, the water inlet groove 471, and the water outlet 431 are all distributed on both sides, the water flow can start making ice on the heat conducting sheets 45 on both sides at the same time, further improving the ice making efficiency; therefore, the evaporators 40 arranged on both sides can make four groups of ice at the same time.

[0055] Further references Fig.13 A V-shaped partition plate 422 is installed on one side of the middle of the water distribution tank 42.

[0056] In a further embodiment, the water entering the water distribution trough 42 from the U-shaped tube 41 will first contact and collide with the V-shaped partition 422 for guidance, so that the water flow is more evenly distributed in the water distribution trough 42 and discharged from the diversion hole 421, thereby improving the water distribution efficiency. When the water flow enters the water distribution trough 42 at a high speed from the U-shaped tube 41, the V-shaped partition 422 plays a buffering role, reducing the direct impact of the water flow on the inner wall of the water distribution trough 42. This helps to reduce noise and extend the service life of the water distribution trough.

[0057] Further, a plurality of triangular grids 46 are evenly distributed on the surface of the heat conducting sheet 45. One ice cube is produced between every two grids 46, that is, ice cubes are formed between the grids 46.

[0058] refer to Figure 7-Figure 9 An ice discharge port 12 is provided at one end of the box body 10 , and blocks 101 are provided on the inner walls of both sides of the box body 10 . An ice collecting plate 60 is obliquely installed on the block 101 , and a through hole 61 is opened at one end of the bottom surface of the ice collecting plate 60 .

[0059] In the above scheme, during the ice-shedding process, the heat conducting sheet 45 absorbs the high-temperature heat in the cold pipe 44, and the ice cubes slide down from the heat conducting sheet 45 and contact the surface of the guide block 47. The guide block 47 guides the ice cubes into the box body 10, that is, the ice cubes fall into the ice collecting plate 60 for storage; the two ends of the ice collecting plate 60 are inclined, and the inclined part can help the ice cubes to be concentrated under the ice collecting plate 60; the ice stored for a long time on the ice collecting plate 60 will melt, and the melted water will flow to the through hole 61 in the inclined direction due to the inclined installation of the ice collecting plate 60, and then fall from the through hole 61 and return to the inside of the collecting tank 11 for recycling; the water discharged from the through hole 61 can avoid water retention on the ice collecting plate 60 and reduce the melting rate of the ice cubes on the ice collecting plate 60.

[0060] Further references Fig. 9 A motor 63 is installed on the end of the box body 10 away from the ice discharge port 12. The bottom of the ice collecting plate 60 is in an arc shape. A screw rod 64 is installed on the output end of the motor 63. The screw rod 64 is concentric with the bottom arc of the ice collecting plate 60, and the screw rod 64 extends to the ice discharge port 12.

[0061] In a further embodiment, the ice cubes stored on the ice collecting plate 60 are distributed between the spiral plates on the spiral rod 64. By starting the motor 63, the spiral rod 64 rotates, and the spiral plates push the ice cubes to the ice discharge port 12 for discharge.

[0062] Embodiment 2 (combined with embodiment 1):

[0063] refer to Figure 2-Figure 6 and Fig.14 The DIY ice making set comprises an ice making box 50, a cold box 51 is arranged inside the ice making box 50, one end of the cold box 51 is connected to the capillary tube 27, the other end of the cold box 51 is connected to the de-icing valve 26 pipeline, a separation box 52 is placed on the cold box 51, and a plurality of ice grooves 53 are arranged in the separation box 52.

[0064] In the above scheme, the above description is as follows: when the user wants to activate the DIY ice making group for DIY ice making, water is filled in the ice trough 53, the first ice making valve 24 is closed, and the second ice making valve 25 is opened. The low-temperature and high-pressure liquid enters the cold box 51 after being throttled by the capillary 27. The separation box 52 absorbs the heat on the cold box 51, and the water stored in the ice trough 53 begins to condense to produce ice cubes. Similarly, in the deicing state, the deicing valve 26 is opened, the capillary 27 forms a pressure barrier, and the high-temperature and high-pressure gas pressed by the compressor 22 will flow to the direction of the deicing valve 26 and enter the cold box 51 to melt the ice cubes and form deicing. Handles are provided at both ends of the separation box 52. The separation box 52 is removed from the cold box 51 by the force of the handles, and the separation box 52 is turned over to make the ice cubes in the ice trough 53 fall out.

[0065] Further references Fig.14 The ice groove 53 is in the shape of a circle, an ellipse or a polygon.

[0066] The ice trough 53 adopts a structural design of different shapes and is equipped with a replaceable separation box 52 mold structure, allowing users to replace the mold according to needs to make personalized ice cubes in heart shape, star shape, irregular shape, etc. In addition, users can add different drinks such as milk and cola into the mold to make ice cubes of various flavors, further enhancing the fun and applicability of the product.

[0067] Embodiment 3 (combined with embodiment 1):

[0068] refer to Figure 8 and Fig. 9 A notch 62 is symmetrically provided at one end of the ice collecting plate 60, a drainage end 49 is provided at the tail end of the water guide groove 48, and the drainage end 49 is above the notch 62, and the bottom of the water guide groove 48 gradually widens from left to right.

[0069] In the above scheme, the gradually widening water guide groove 48 can conveniently guide water to the drainage end 49 quickly, and the water flows out from the drainage end 49. Since the drainage end 49 is above the notch 62, the excess water from refrigeration will directly flow from the drainage end 49 into the notch 62, that is, the water directly enters the box 10 and gathers in the collection groove 11, which reduces the retention time of water in the water guide groove 48; it ensures that the excess water will not drip onto the ice collecting plate 60 during the refrigeration process, thereby effectively separating the flow direction of ice cubes and water. This not only keeps the ice collecting plate clean, but also avoids water from mixing into the ice cubes, thereby improving the purity and quality of the ice cubes.

[0070] Embodiment 4:

[0071] Electronic control system: This ice maker adopts PLC integrated intelligent electronic control system. Users can conveniently select different ice making modes and timing functions through the control panel or mobile application, simplifying the operation process and improving user experience.

[0072] The specific implementation process of the present invention is as follows:

[0073] Working process of water circuit: the water used for ice making is stored in the raw water tank 14. When the ice maker is working, the water in the raw water tank 14 is firstly extracted by the water pump 16 through the input pipe 18, and the water is transported to the inside of the box body 10 through the first output pipe 17. There is a water level float in the box body 10 (not clearly indicated in the figure). The float senses and controls the start and stop of the water pump 16. When the water in the box body 10 reaches a certain height, the water pump 16 stops pumping water; then the ice making pump 15 extracts the water in the box body 10, and sends the water into the U-shaped pipe 41 through the second output pipe 19; the water is diverted by the U-shaped pipe 41 to the water distribution troughs 42 at both ends. The water fills the water distribution groove 42, is discharged from the diversion hole 421 into the diversion groove 43, and the water flows downward from the water outlet 431, and the water evenly contacts the surface of the heat conductive plate 45; the low-temperature and high-pressure liquid enters the cold pipe 44 through the capillary 27, and the heat conductive plates 45 on both sides of the cold pipe 44 absorb the heat of the cold pipe 44, so that ice cubes gradually solidify on the surface of the heat conductive plates 45 to form ice cubes; and the flowing unsolidified water is drained along the heat conductive plates 45 to the water inlet groove 471 and then enters the water guide groove 48, and the water guide groove 48 discharges the unsolidified water back into the box body 10, thereby forming a reciprocating circulation of the water circuit.

[0074] The working process of ice making by compressor 22: After the compressor 22 works, high-temperature and high-pressure gas is compressed by the compressor 22, and after heat exchange with the condenser 23, it becomes low-temperature and high-pressure liquid, and after passing through the drying filter to filter the residual moisture, the first ice-making valve 24 is normally open, and after throttling through the capillary 27, a high-pressure liquid is formed in the cold pipe 44, and the pressure is instantly lost to form low-temperature gas for ice making and heat exchange; after the heat exchange is completed, the compressor 22 inhales air, forming a reciprocating cycle working state. When the user wants to enable the DIY ice-making group to make DIY ice, fill water in the ice tank 53, close the first ice-making valve 24, open the second ice-making valve 25, and the low-temperature and high-pressure liquid enters the cold box 51 after throttling through the capillary 27, and the separation box 52 absorbs the heat on the cold box 51, and the water stored in the ice tank 53 begins to condense to produce ice cubes. After the heat exchange is completed, the compressor inhales air, forming a reciprocating cycle working state.

[0075] Deicing process: Deicing valve 26 is opened, capillary 27 forms a pressure barrier, so the high-temperature and high-pressure gas pressed out by compressor 22 will flow to deicing valve 26 and enter cold pipe 44 or cold box 51 to melt ice cubes and form deicing. Heat conducting sheet 45 absorbs the high-temperature heat in cold pipe 44, ice cubes slide down from heat conducting sheet 45 and contact the surface of guide block 47, which guides ice cubes into box 10, that is, ice cubes fall into ice collecting plate 60 for storage. (Note: ice making and deicing by compressor 22 are existing technical solutions).
