Description

Technical Field

[0001] The invention relates to the technical field of heating and refrigeration, and in particular to a rapid ice-making structure of an ice-making machine. Background Art

[0002] The ice maker uses an evaporator to cool the air. The refrigerant circulates to lower its surface temperature. Water freezes after contacting the evaporator. After ice making is completed, the heating device heats the evaporator. As the temperature rises, the adhesion between the ice cubes and the evaporator decreases, thereby achieving rapid ice removal. In this way, people can quickly get the ice cubes they need. Therefore, ice makers are convenient and efficient, and are widely favored by people.

[0003] However, existing ice makers still have some problems: First, when making bullet ice, the inner wall of the ice cube is limited by the shape of the evaporator tube, and the inner wall of the ice cube is a grooved cylindrical shape that matches the evaporator tube. When this ice cube is put into the beverage, due to the presence of voids inside, the contact area between the ice cube and the beverage is significantly increased compared to solid ice cubes, so the speed of heat interaction is faster, which causes this bullet ice cube to melt more easily during use.

[0004] In daily life scenarios, for example, when making a cup of iced coffee or iced tea, if the user cannot finish the drink quickly, the ice cubes will continue to get smaller until they are completely melted during the waiting time due to the rapid melting speed of the ice cubes. This is a very undesirable situation for those who like to savor the drink slowly and enjoy the cool taste. In order to keep the drink cold, the user has to make more ice cubes, which not only increases the workload of the ice maker, but also leads to energy waste, because the ice maker needs to consume electricity to make more ice cubes, and too many ice making times will increase power consumption.

[0005] In addition, during the ice-making process, different degrees of freezing force will be formed on the contact surface between the bullet ice and the evaporator tube due to temperature differences and the freezing of water. In some parts of the evaporator tube, the freezing force is stronger due to factors such as slightly lower local temperature or surface roughness. The cylindrical shape of the bullet ice is prone to twisting when subjected to uneven freezing force. When the defrosting process begins, this twisting tendency will cause the bullet ice to rotate on the evaporator tube. That is, when the initial defrosting force acts on one side of the bullet ice, due to the limitation of its shape, the bullet ice cannot be directly detached smoothly, but will rotate along the surface of the evaporator tube.

[0006] This rotation increases the contact time between the bullet ice and the evaporation tube, making it easier to melt. When holding small parties or outdoor activities, if this bullet ice is used to cool drinks, ice cubes need to be frequently replenished, which affects the continuity of the activities. For some companies, if this easy-to-melt bullet ice is used, operating costs will increase because more ice reserves are required and ice cubes need to be checked and replenished more frequently, which undoubtedly increases labor and material costs.

[0007] Secondly, after using the ice maker, the user needs to drain the remaining water and condensed water inside it. This is because when making ice, the low temperature of the evaporator causes a large amount of water vapor in the surrounding air to condense. At the same time, some of the ice-making water will remain inside the machine after the ice-making cycle is completed. These factors together lead to a large amount of water stored inside.

[0008] Secondly, from a safety perspective, water splashing onto sockets, wires or other electrical equipment will increase the risk of electrical short circuits, thereby affecting the power supply of the entire household. What is more serious is that the electric sparks generated by the short circuit will ignite surrounding flammable materials, causing a fire, posing a huge threat to household property and personal safety.

[0009] To this end, the present invention proposes a rapid ice-making structure for an ice-making machine. Summary of the Invention

[0010] The object of the present invention is to provide a rapid ice-making structure for an ice-making machine to solve the problems raised in the above background technology.

[0011] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a rapid ice-making structure for an ice maker, comprising a main unit, an evaporator installed inside the main unit, a plurality of evaporation tubes installed below the evaporator, a partition fixedly connected to the inner wall of the evaporator provided inside each of the evaporation tubes, a cold and hot combined de-icing assembly provided below the evaporator, the cold and hot combined de-icing assembly comprising a plurality of through grooves, each of the through grooves being opened at the bottom of each corresponding evaporation tube, and the shape of the through grooves matching the flow path of the cooling medium.

[0012] Preferably, the bottom of the partition extends downward to above the through groove, the through groove is configured to be U-shaped, and the edges thereof are all rounded.

[0013] Preferably, the outer surface of each evaporation tube is fixedly connected with a plurality of fins arranged in an annular shape and at equal intervals. The fins are all arranged in a trapezoidal shape and are located at one end of the evaporation tube close to the evaporator.

[0014] Preferably, the inner wall of each evaporation tube is provided with a plurality of protrusions, and the tube wall of each evaporation tube is provided with a plurality of gas grooves arranged in an annular shape and at equal intervals.

[0015] Preferably, the plurality of protrusions are all arranged at the upward bending portion of the inner wall of the bottom side of the evaporation tube, the gas grooves are filled with air, and the gas grooves are all arranged at the upper middle portion of the evaporation tube.

[0016] Preferably, during the ice making process, the upper limit of the water level does not exceed the top of the fin.

[0017] Preferably, a flip cover is installed on the top of the main unit, an ice discharging structure is installed inside the main unit and below the evaporator, and an ice storage box is provided inside the main unit and on a side away from the evaporator.

[0018] Preferably, a drainage groove is provided inside the main unit, a buckling ring is installed below the drainage groove, and a buckling plug is installed below the main unit, and the buckling plug can seal the buckling ring at one end close to the buckling ring.

[0019] Preferably, an elastic guide assembly is provided inside the main unit, and the elastic guide assembly includes a sealing disk fixedly connected to the inside of the drain groove, the sealing disk penetrates the surface and is provided with diversion holes arranged equidistantly in a ring shape, a spring is fixedly connected below the sealing disk, an elliptical plug is fixedly connected below the spring, and an elastic one-way valve is installed below the sealing disk and at the center of the diversion hole.

[0020] Preferably, grooves are provided on both sides of the drainage groove, and a convex rod is fixedly connected to the outer surface of the elliptical plug and extends into the groove. The elliptical plug is slidably connected to the inside of the groove through the convex rod. A notch is provided on the top of the elliptical plug, and the spring is installed inside the groove. A spherical protrusion is installed at the bottom of the elastic one-way valve, and the elastic one-way valve is set as an elastic starting mechanism. The bottom of the elliptical plug is set to an elliptical shape, and the top of the elliptical plug is set to a hemispherical shape.

[0021] Preferably, the elastic one-way valve is arranged with its opening direction facing the side close to the middle of the drainage groove.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By providing a through groove at the bottom of the evaporating tube, the area that can be formed into ice is significantly increased. The larger ice area makes the structure of the ice cube more complete, thereby optimizing the heat exchange characteristics of the ice cube. When put into the beverage, compared with the traditional bullet ice, the contact area between the ice cube and the beverage is relatively reduced. According to the principle of heat conduction, the smaller the contact area, the slower the heat exchange rate, thereby effectively reducing the melting rate of the ice cube during use. This feature can ensure that the ice cube remains solid for a longer time, maintains the low temperature of the beverage, and improves the user's drinking experience, whether it is for individuals to slowly enjoy iced coffee or iced tea at home or for providing cold drinks to customers.

[0023] Among them: when shedding ice, the increased ice area makes the center of gravity distribution of the ice body more reasonable. When the shedding force acts on the ice cube, due to the reasonable center of gravity, the ice cube can more stably accept the effect of the shedding force, avoiding the twisting or irregular movement that is easy to occur in the traditional bullet ice during the shedding process due to shape and center of gravity problems.

[0024] Among them: From the perspective of the overall operating efficiency of the ice maker, the structural improvement of the present invention avoids the situation in which traditional ice makers need to make ice frequently to compensate for the rapid melting of ice cubes. Reducing the number of ice making times not only reduces the workload of the ice maker, but also reduces the power consumption of the ice maker. For home users, it can save electricity costs, and for enterprises, it can reduce operating costs, including reducing the loss of ice makers and labor costs.

[0025] Among them: the fins can enhance the heat conduction capacity between the evaporating tube and the surrounding environment. From the principle of heat exchange, heat transfer is proportional to the surface area. The presence of fins enables the evaporating tube to absorb heat from the surrounding environment more efficiently, thereby accelerating the ice-making process.

[0026] The presence of the bumps changes the flow of the medium inside the evaporator tubes. According to the principles of fluid mechanics, the bumps disturb the medium, making the flow more complex and turbulent, thereby helping to disrupt the laminar flow of the water flow and thereby improving heat exchange efficiency. Furthermore, the bumps can guide the formation of ice cubes to a certain extent, making the ice cubes more evenly distributed around the evaporator tubes during growth. This avoids irregular ice shapes caused by localized excessively fast or slow ice growth, further improving ice quality.

[0027] Among them: when the ice-shedding process begins, the gas in the air tank expands due to the increase in temperature. According to the ideal gas state equation, when the temperature rises, the pressure will increase while the amount of gas substance remains unchanged. The increased pressure will produce an outward pressure on the ice, which can push the ice to fall off faster.

[0028] Among them: the downward extension of the partition will occupy a certain amount of space, thereby reducing the internal space of the evaporator tube. According to the principles of fluid mechanics, when the flow rate remains unchanged, the reduction in the space in the pipe will lead to an increase in flow rate. During the ice-making process, this increase in flow rate can increase the flow speed of the refrigerant medium in the evaporator tube, thereby enhancing the heat exchange effect, thereby accelerating the ice-making speed and improving the working efficiency of the ice-making machine. It also helps to improve the quality of ice making, making the crystals of ice cubes more uniform and fine.

[0029] Among them: the design of the through groove of the present invention helps to improve the shape of the ice, so that the prepared ice cubes have additional ice shape area. When the user bites the ice cubes, the raised ice cubes can disperse the bite force, making it easier for the user to bite, thereby improving the taste.

[0030] 2. By snapping the plug against the elliptical plug, the elastic one-way valve's restriction on the diversion hole is unlocked, and the water flow is guided under the elliptical guidance of the elastic one-way valve to avoid water splashing. The benefit of this improvement is that it greatly enhances the user experience. In home use scenarios, such as family gatherings or daily beverage making, users no longer need to worry about the surrounding environment getting wet when draining after using the host. There is no need to spend extra time cleaning the countertop where the host is placed, nearby cabinet surfaces, the ground and other areas, and it will not wet other electrical appliances in the kitchen, such as microwave ovens and ovens, which reduces the user's maintenance burden.

[0031] Among them: when a large amount of accumulated water inside the ice maker begins to be discharged, the diversion hole can disperse the concentrated water flow, which helps to reduce the local pressure and flow rate of the water flow, allowing the water to flow through the buckle ring more smoothly and orderly.

[0032] When water strikes the elastic one-way valve, it is reflected by the valve and the inner wall of the drain channel, causing the water to flow toward the center and converge at the bottom of the elliptical plug. This design effectively controls the flow direction and prevents disordered diffusion of the water.

[0033] While achieving the above-mentioned beneficial effects, the present invention also has the following advantages: from a cost perspective, the elastic guide component is low-cost, and while solving the problem of splashing water, it will not add too much cost burden to the production of the host. Moreover, the spring in the structure is protected by the elliptical plug. At the same time, under the restriction of the opening direction of the elastic one-way valve, the water flow will not touch the spring, which makes the maintenance cost of the entire structure very low. This low-cost, low-maintenance cost structure is very suitable for use in home hosts. At the same time, its easy-to-operate feature also facilitates user use. Both ordinary home users and corporate employees can operate it easily, and it has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0048] It should be noted that the evaporator 12 and the evaporation tube 121 only provide the function of forming and melting ice cubes, and the structure and working principle of the evaporator 12, the evaporation tube 121 and the partition 122 belong to the existing technology, so they will not be described in detail later. Similarly, the ice discharge structure in the present invention only provides the function of allowing ice cubes to be moved to the inside of the ice storage box, and the structure and working principle of the ice discharge structure also belong to the existing technology, so they will not be described in detail later.

[0049] Example 1, please refer to Figures 1 to 5As shown, a fast ice-making structure of an ice maker includes a main unit 11, an evaporator 12 is installed inside the main unit 11, and a plurality of evaporation tubes 121 are installed below the evaporator 12. A partition 122 fixedly connected to the inner wall of the evaporator 12 is provided inside each evaporation tube 121. A cold and hot combined de-icing component 2 is provided below the evaporator 12. The cold and hot combined de-icing component 2 includes a plurality of through grooves 21. The through grooves 21 are all opened at the bottom of each corresponding evaporation tube 121, and the shape of the through grooves 21 matches the flow path of the cooling medium.

[0050] Please refer to Figures 4 to 8 As shown, the outer surface of each evaporation tube 121 is fixedly connected with a plurality of fins 22 arranged in a circular and equidistant manner. The fins 22 are all arranged in a trapezoidal shape, and the fins 22 are all located at one end of the evaporation tube 121 close to the evaporator 12. The inner wall of each evaporation tube 121 is installed with a plurality of protrusions 23, and the tube wall of each evaporation tube 121 is provided with a plurality of gas grooves 24 arranged in a circular and equidistant manner.

[0051] Specifically, when the user pours water into the main unit 11, the ice-making process starts immediately. First, the evaporator 12 starts to cool. The cooling medium in the evaporator 12 undergoes a phase change in the refrigeration cycle and absorbs heat, thereby gradually reducing the temperature of the evaporator 12. Since there is a heat conduction relationship between the evaporator 12 and the evaporation tube 121 below, the temperature of the evaporation tube 121 also decreases under the influence of the cooling of the evaporator 12. At this time, water begins to freeze on the surface of the evaporation tube 121.

[0052] During the ice-making process, the internal structure of the evaporation tube 121 has an important influence on the ice-making efficiency.

[0053] Please refer to Figure 6 As shown, when the cooling medium flows in the evaporator tube 121, since the bottom of the partition 122 extends downward to the top of the through groove 21, this design causes the partition 122 to occupy a certain space inside the evaporator tube 121. According to the principles of fluid mechanics, when the flow rate of the cooling medium remains unchanged, the reduction in space will lead to an increase in flow rate. This increase in flow rate is of great significance to the ice-making process. It can significantly enhance the heat exchange efficiency between the cooling medium and the tube wall of the evaporator tube 121, which means that the evaporator tube 121 can absorb heat from the surrounding water more quickly, thereby accelerating the ice-making process.

[0054] At the same time, the presence of the through grooves 21 significantly increases the area where ice can be formed, making the structure of the formed ice cubes more complete. This complete structure optimizes the heat exchange characteristics of the ice cubes.

[0055] Specifically, when ice cubes are put into beverages, their contact area with the beverage is relatively reduced compared to traditional bullet ice. According to the principle of heat conduction, the smaller the contact area, the slower the heat exchange rate. This feature effectively reduces the melting rate of ice cubes during use. During ice making, the through groove 21 provides more favorable conditions for the formation of ice, enabling the ice to grow more evenly around the evaporation tube 121, thereby avoiding ice quality problems caused by unreasonable local structure, such as uneven crystallization or inconsistent density inside the ice cube.

[0056] At the same time, the presence of the fins 22 also produces positive changes in the heat exchange environment around the evaporation tube 121.

[0057] Specifically, from the perspective of heat exchange, the fins 22 have a larger surface area. According to the relationship that heat transfer is proportional to surface area, the fins 22 can enhance the heat conduction capacity between the evaporation tube 121 and the surrounding environment, which enables the evaporation tube 121 to absorb heat from the surrounding environment more efficiently, thereby further accelerating the ice-making process. Moreover, the trapezoidal design of the fins 22 helps to guide the direction of heat transfer, so that heat can be absorbed more concentratedly, which not only improves the ice-making efficiency, but also makes the temperature distribution during the ice-making process more uniform, avoiding the problem of uneven ice quality due to local temperature differences, and ensuring that the quality of the ice cubes produced is more stable and reliable.

[0058] In addition, when the medium flows in the evaporation tube 121, the protrusions 23 will disrupt the laminar flow state of the medium, making the flow state of the medium complex and turbulent, thereby promoting the contact between the medium and the evaporation tube 121, further accelerating the ice-making process. At the same time, the protrusions 23 guide the formation direction of the ice cubes to a certain extent, so that the ice cubes can be more evenly distributed around the evaporation tube 121 during the growth process, avoiding the problem of irregular ice shape caused by local ice cubes growing too fast or too slow, and further improving the quality of the ice cubes.

[0059] After ice making is completed, the medium inside the evaporator 12 begins to condense and releases heat to gradually melt the ice on the surface of the evaporation tube 121. Under the action of gravity, the ice begins to fall.

[0060] During this process, since the temperature of the evaporation tube 121 increases, according to the ideal gas state equation, when the amount of gas substance remains unchanged, the temperature increase will lead to an increase in pressure.

[0061] Therefore, the air in the gas tank 24 expands due to heat, and the increased pressure will produce an outward pressure on the ice cubes. This pressure will generate an additional force to partially push the ice cubes, thereby accelerating the ice cubes to fall off the evaporation tube 121, effectively reducing the residence time of the ice cubes on the evaporation tube 121, avoiding the problem of ice cubes melting due to long-term contact, and thus improving the ice removal efficiency.

[0062] Finally, after ice making is completed, the ice discharging structure pushes the ice cubes into the ice storage box, completing an ice making operation.

[0063] It should be noted that the bottom of the partition 122 extends downward to the top of the through groove 21. The through groove 21 is set to be U-shaped, and its edges are rounded. Several protrusions 23 are set at the upward bend of the inner wall of the bottom side of the evaporator tube 121. The gas groove 24 is filled with air, and the gas grooves 24 are all set at the upper middle part of the evaporator tube 121. During the ice making process, the upper limit of the water level does not exceed the top of the fin 22. A flip cover is installed on the top of the main unit 11, and an ice discharge structure is installed inside the main unit 11 and below the evaporator 12. An ice storage box is provided inside the main unit 11 and on the side away from the evaporator 12. The cooling medium in the evaporator 12 can be specifically implemented as Freon.

[0064] Example 2: Based on Example 1, please refer to Figure 9 and Figure 10 As shown, a drainage groove is provided inside the main unit 11, and a snap ring is installed below the drainage groove. A snap plug is installed below the main unit 11, and the snap plug can seal the snap ring at one end close to the snap ring. An elastic guide component 3 is provided inside the main unit 11, and the elastic guide component 3 includes a sealing disk 31 fixedly connected to the inside of the drainage groove. The sealing disk 31 penetrates the surface and has diversion holes 32 arranged in a ring-shaped and equidistant manner. A spring 33 is fixedly connected below the sealing disk 31, and an elliptical plug 34 is fixedly connected below the spring 33. An elastic one-way valve 35 is installed below the sealing disk 31 and at the center of the diversion hole 32.

[0065] It should be noted that grooves are provided on both sides of the drain groove, and a convex rod is fixedly connected to the outer surface of the elliptical plug 34 and extends into the groove. The elliptical plug 34 is slidably connected to the inside of the groove through the convex rod. A notch is provided on the top of the elliptical plug 34, and the spring 33 is installed inside the groove. A spherical protrusion is installed at the bottom of the elastic one-way valve 35. The elastic one-way valve 35 is set to an elastic starting mechanism. The bottom of the elliptical plug 34 is set to an elliptical shape, and the top of the elliptical plug 34 is set to a hemispherical shape. The elastic one-way valve 35 is set to open in a direction toward the side close to the middle of the drain groove. The elastic one-way valve 35 includes a valve body, a valve core, a rotating shaft and a torsion spring. The valve core is fixedly connected to the rotating shaft, the torsion spring is fixedly connected between the rotating shaft and the valve body, and the spherical protrusion is set at the bottom of the valve body. The spring 33 is in a contracted state in the initial state.

[0066] Specifically, based on the first embodiment, there will be water inside the host 11 after the ice making is completed. This water mainly comes from two parts. One part is the residual water that did not participate in the freezing process during the ice making process. Since it is difficult to achieve 100% conversion of water into ice during the ice making process, there will always be some water remaining; the other part is during the ice making process, due to the refrigeration of the evaporator 12, the internal temperature of the host 11 is reduced, and the water vapor in the air will condense into condensed water when it is cooled. These two parts of water remain together inside the host 11.

[0067] After the ice making operation is completed, the water inside the main unit 11 needs to be drained.

[0068] At this time, when the user needs to remove the snap-fit ​​plug from the snap-fit ​​ring, the upward pressure on the elliptical plug 34 disappears, and the spring 33 is no longer under pressure and is in an extended state. At this time, the spring 33 drives the elliptical plug 34 to slide toward the bottom of the host 11. As the elliptical plug 34 moves, the elliptical plug 34 no longer blocks the spherical protrusion under the elastic one-way valve 35. Due to the special structure of the elastic one-way valve 35, when the spherical protrusion is no longer blocked, the elastic one-way valve 35 opens based on the force of the torsion spring.

[0069] At this time, the water in the main unit 11 will flow downward through the sealing disk 31 and the diversion hole 32, and the diverted water will then continue to flow through the elastic one-way valve 35. Since the opening direction of the elastic one-way valve 35 is set to the side close to the middle of the drain groove, the water will be guided by the valve core of the elastic one-way valve 35 during the flow. When the water flow contacts the valve core, it will be reflected to the inner wall of the drain groove, and then guided by the inside of the drain groove and the side of the valve core close to the elliptical plug 34, the water will flow along the outer surface of the elliptical plug 34. Due to the elliptical design of the bottom of the elliptical plug 34, the water flow will not disperse, but will converge to one point for discharge.

[0070] When the drainage is completed, the user inserts the snap-fit ​​plug into the snap-fit ​​ring again. At this time, the snap-fit ​​plug blocks the snap-fit ​​ring so that the elliptical plug 34 is subjected to upward pressure. The elliptical plug 34 moves upward, and the spring 33 is compressed again. At the same time, the upward movement of the elliptical plug 34 will again block the spherical protrusion under the elastic one-way valve 35. The elastic one-way valve 35 is closed, and the entire elastic guide assembly 3 is reset, waiting for the next drainage operation.

[0071] It should be noted that the spring 33 will not be corroded by the water flow under the protection of the elliptical plug 34 and the setting of the opening direction of the elastic one-way valve 35, thereby reducing the rust phenomenon. The elliptical plug 34 has a certain shielding effect on the spring 33, preventing the water flow from directly impacting the spring 33. At the same time, the opening direction of the elastic one-way valve 35 makes the water flow mainly along a specific direction when passing through, rather than rushing towards the spring 33, further protecting the spring 33.

[0072] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
