Description

Technical Field

[0001] The invention relates to the technical field of refrigeration, in particular to an ice storage type ice making machine. Background Art

[0002] An ice maker is a convenient and efficient refrigeration device that can quickly produce ice cubes to meet the needs of various iced drinks and delicacies.

[0003] But there are still some problems with the existing ice making machines:

[0004] First, from the perspective of ice-making efficiency, the existing technology forms ice cubes through cooling of the copper tube under the condenser. However, the area of ​​the copper tube used for ice making is only its circumference. This limited contact area seriously restricts the speed of ice making. Due to the small contact area, the efficiency of heat exchange is relatively low. During the ice-making process, it takes a long time for the refrigeration capacity to completely freeze the water into ice, which increases the time required for ice making. For users, the slow ice-making speed of the ice maker will greatly reduce their demand for use. Secondly, because the contact area between the copper tube and the water is only the circumference, the heat transfer of the outer layer of water during the freezing process is not uniform and rapid enough, which will also lead to uneven density of the outer layer of ice cubes, with more gaps inside or the ice crystal structure not being tight enough, and the ice cubes will melt faster when used.

[0005] In the process of ice cubes falling off, when the copper tube heats the ice cubes, although the ice cubes can fall off the copper tube, the inner wall of the ice cubes will become hot due to direct contact with the copper tube. In the process of ice cubes falling, the residual heat of the copper tube will continue to heat the upper part of the ice cubes. Since the upper part of the ice cubes is heated for a longer time when they fall, the resulting ice cubes are easier to melt. This easy melting characteristic is very disadvantageous for both the storage and use of ice cubes.

[0006] Finally, the small ice-making area leads to a long ice-making time, and the unreasonable use of heat during the heating process will increase the energy consumption of the ice maker, resulting in unnecessary waste of energy.

[0007] Secondly, when the ice cubes fall, the prior art will use a specific mechanism to push the ice cubes into the ice storage bin. As the ice cubes accumulate in the ice storage bin, the cold air sinks, making the ambient temperature of the upper ice cubes relatively high. Since the heat exchange area between the upper ice cubes and the outside world is large, this accelerates the heat transfer process. Therefore, the continuous heat exchange causes the upper ice cubes to melt continuously, which on the one hand causes waste of ice cubes and reduces the effective ice making capacity of the ice maker. On the other hand, if the melted water accumulates in the ice storage bin, it will increase the humidity in the ice storage bin. The high humidity environment will cause the water molecules on the surface of the ice cubes to interact with the tiny flaws or roughness on the surface of the bin wall, and the water molecules will gradually solidify and adhere to the bin wall. As time goes by, the solidified ice cubes will become more and more, gradually forming a thicker ice layer on the bin wall. This ice layer will not only reduce the effective volume of the ice storage bin, reducing the amount of ice cubes that can be stored, but also when it is necessary to take out the ice cubes, the ice cubes solidified on the bin wall will also cause inconvenience to the operation, and require additional tools or manpower to clean, increasing the cost of use and the difficulty of operation.

[0008] Although adding a refrigeration mechanism dedicated to ice storage inside the ice storage bin can alleviate the above problems to a certain extent, the significantly increased cost is also a factor that cannot be ignored. For ice machine manufacturers, adding a refrigeration mechanism means higher production costs, which will lead to an increase in the selling price of the ice machine, thereby reducing its competitiveness in the market. For consumers, the purchase cost will increase. At the same time, the operation of the refrigeration mechanism also requires additional energy, which will further increase the cost of use.

[0009] To this end, the present invention proposes an ice storage type ice making machine. Summary of the invention

[0020] Preferably, the speed-increasing fins are all inclined toward a side close to the evaporation tube, the cross-sectional area of ​​the microchannel gradually decreases from top to bottom, and the opening directions of the speed-increasing fins are all set to face downward.

[0021] Preferably, surfaces of the first heat exchange fin and the second heat exchange fin are coated with a hydrophobic coating.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention improves the problems of low ice making efficiency and fast melting speed of ice cubes in the prior art through an efficient and energy-saving ice-removing assembly. First, the raised stripes increase the cooling area of ​​the evaporating tube and the ice cubes, thereby enhancing the cooling effect. At the same time, due to its inclined posture, when the ice cubes are heated to fall off, the ice cubes are not only subject to gravity, but also to a downward guiding force. This guiding force can accelerate the speed at which the ice cubes fall off the evaporating tube, effectively improving the problem of excessive heating melting the ice cubes in the prior art.

[0024] Compared with the prior art, the high-efficiency and energy-saving de-icing assembly increases the refrigeration area, so that water can be frozen into ice faster, which greatly shortens the time required for ice making and can better meet the needs of users for ice cubes. At the same time, the quality of ice cubes is also improved, with more uniform density and tighter ice crystal structure, which melts more slowly during use. In the process of ice cube shedding, the problem of ice cube melting caused by heating is reduced, and the storage and use performance of ice cubes is improved. In addition, due to the shortened ice making time and more reasonable heat utilization, the energy consumption of the ice maker is also effectively reduced, saving energy.

[0025] Among them: since the surface of the striped protrusion is provided with a plurality of friction concave points, these friction concave points are sunken, so during the melting process of ice cubes, the ice inside the friction concave points melts and forms water, which plays a lubricating role, which helps the ice cubes to move on the surface of the evaporator, making it easier for the ice cubes to fall off the evaporator;

[0026] Among them: because the edge of the stripe protrusion is provided with a micro-channel, its cross-sectional area gradually decreases from top to bottom, so the micro-channel can increase the speed of ice cube sliding down. When the ice cube slides down on the surface of the stripe protrusion, the shape of the micro-channel can reduce the resistance of the ice cube sliding down, so that the ice cube can leave the evaporator more quickly, thereby improving the overall working efficiency of the body;

[0027] The speed-up fins are offset toward the center of the evaporator tube, and their openings are facing downward. First, the speed-up fins increase the contact area and enhance the cooling effect. Second, when the ice cubes slide down, the ice pieces in the openings inside the speed-up fins are blocked and broken. Under the guidance of the speed-up fins and the striped protrusions, the broken ice pieces will continue to slide down and impact the surface of the ice cubes, providing them with tiny kinetic energy, which helps the ice cubes fall off the evaporator more quickly.

[0028] Among them: the dovetail groove reduces vibration and improves stability by limiting the movement of ice cubes, thereby reducing the loss of kinetic energy and helping the ice cubes move more smoothly on the evaporator;

[0029] While achieving the above beneficial effects, the present invention also has the following advantages:

[0030] First, the inner wall of the ice cubes produced by the energy-efficient deicing assembly has a groove shape under the guidance of the striped protrusions, that is, its surface area is increased, and thus the contact area with the beverage is increased, so that the heat transferred from the beverage to the ice cubes per unit time is increased, thereby being able to reduce the temperature of the beverage more quickly;

[0031] Second, when the beverage comes into contact with ice cubes, due to the temperature difference, the hotter beverage around it will flow into the groove, forming local convection. This convection will accelerate the transfer of heat, causing the overall temperature of the beverage to drop faster.

[0032] Third, the grooves increase the complexity of the internal structure of the ice cube, making the heat transfer path inside the ice cube longer. When the ice cube is in the external environment, the heat needs to go through more paths to reach the inside of the ice cube, thereby delaying the melting process of the entire ice cube.

[0033] 2. The cold air naturally sinks to the bottom of the ice storage bin, and as the subsequent cold air continues to be generated and sinks, the cold air at the bottom enters the output bin through the input bin under pressure, and then is discharged to the top of the ice storage bin, forming a cold air circulation system, thereby automatically and continuously freezing the ice stored in the ice storage bin without the need for a driving source;

[0034] Compared with the prior art, the upper ice cubes will be continuously cooled by circulating cold air due to the large contact area and the continuous loss of cold air. The unpowered cold air circulation component can continuously cool the upper ice cubes by circulating cold air, thereby reducing the heat exchange with the outside world, thereby greatly reducing the melting speed of the ice cubes. In addition, the unpowered cold air circulation component does not require an additional refrigeration mechanism, thereby improving the storage capacity while reducing a certain cost, thereby making the overall more competitive in the market and more economical for consumers to purchase and use.

[0035] Among them: the input bin can prevent ice from accumulating at the bottom of the ice storage bin and thus affecting the cold air circulation effect. Through the additional protrusion of the input bin, even if ice is accumulated at the bottom of the ice storage bin, the cold air can pass through the gap between the input bin and the ice, ensuring the normal circulation;

[0036] Among them: the existence of the guide plate inside the circulation channel reduces the space inside the circulation channel, thereby accelerating the cold air, that is, the space becomes smaller and the flow rate increases. At the same time, due to the increase in the initial speed of the cold air, the cold air can also overcome its own gravity and continue to approach the output bin;

[0037] While achieving the above beneficial effects, the present invention also has the following effects:

[0038] First, based on the water absorption and moisture absorption characteristics of the absorbent cotton cloth itself, the absorbent cotton cloth can absorb part of the cold air and play a role in locking water. When the air inside the circulation channel moves upward, it can take away part of the cold air. Since the absorbent cotton cloth can lock water, it also prevents water droplets from solidifying into ice layers. That is, the absorbent cotton cloth can circulate the cold air while preventing ice formation.

[0039] Secondly, when the first heat exchanger and the second heat exchanger are aligned, they can be regarded as a whole, that is, one end of the whole is in contact with the absorbent cotton cloth, and the other end is in contact with the outside world. Based on heat transfer, the temperature inside the circulation channel is continuously reduced by the whole, further enhancing the cooling effect of the whole machine.

[0040] Thirdly, since the side with a larger opening of the wind scoop faces the outside world and the side with a smaller opening contacts the second heat exchange plate, it can prevent hot air from flowing back in an environment with a temperature difference. If there is no wind scoop, the hot air from the outside will flow into the circulation channel along the second heat exchange plate, destroying the cold air environment of the ice storage bin.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] It should be noted that the evaporator 12 can adopt related products on the market, and its structure and working principle belong to the prior art, so the working principle of the evaporator 12 will be briefly described later. At the same time, the ice-discharging unit 14 is composed of a water basin, a rotating shaft and an ice-discharging shovel, and its main function is to push the ice cubes after the ice making is completed. At the same time, the ice-discharging unit 14 can also adopt related products on the market, and it has been known to the public, so it belongs to the prior art. At the same time, the ice-discharging unit 14 does not play a key role in the embodiment, so its function will be briefly described later.

[0057] Embodiment 1: Figures 1 to 3 As shown, the ice storage type ice maker includes a body 11, an evaporator 12 is installed inside the body 11, a plurality of evaporation tubes 121 are fixedly connected to the bottom of the evaporator 12, and a high-efficiency energy-saving ice-removing component 2 for enhancing the cooling and heating effects of the evaporator 12 is arranged inside the body 11. The high-efficiency energy-saving ice-removing component 2 includes a plurality of striped protrusions 21 fixedly connected to the outer surface of the evaporation tube 121, and the striped protrusions 21 are all inclined and spiral along the outer surface of the evaporation tube 121.

[0058] like Figures 1 to 6As shown, the high-efficiency and energy-saving ice removal component 2 also includes a plurality of friction dimples 22, which are arranged equidistantly in a spiral manner and symmetrically opened on the outer surface of the striped protrusion 21, and the outer surface of the striped protrusion 21 is symmetrically provided with dovetail grooves 23, and the outer surface of the striped protrusion 21 is arranged equidistantly in a spiral manner and symmetrically fixedly connected with a plurality of speed-increasing fins 24, and the edge of the striped protrusion 21 is fixedly connected with a microchannel 25.

[0059] It should be noted that the top of the body 11 is of detachable design, the side close to the evaporator 12 is a fixed end, and the side away from the evaporator 12 is a movable end. A control panel 13 is installed on the top of the body 11 and at the fixed end, and an ice lowering unit 14 is installed on the inner wall of the body 11 and below the evaporator 12. An ice storage bin 15 is installed below the movable end of the body 11. The evaporator 12 and the ice lowering unit 14 are both electrically controlled to start and stop by the control panel 13. The speed-up fins 24 are all inclined toward the side close to the evaporation tube 121, and the cross-sectional area of ​​the microchannel 25 gradually decreases from top to bottom. The opening direction of the speed-up fins 24 is set to face downward.

[0060] Specifically, the operator needs to add water to the ice storage bin 15, and then start the evaporator 12 through the control panel 13. At this time, the evaporator 12 and the evaporation tube 121 begin to refrigerate. Due to the refrigeration effect of the evaporation tube 121, the surface temperature thereof gradually decreases. At this time, water begins to condense into ice on the low-temperature surface of the evaporation tube 121. Due to the existence of the structure of the high-efficiency and energy-saving de-icing component 2, the contact area with water is greatly increased, that is, the ice cubes will fit tightly in the gap between the dovetail groove 23 and the speed-up fin 24, and the inside of the friction concave point 22 will also be filled with ice points. Then, more water can contact the low-temperature surface and condense into ice per unit time, thereby improving the ice-making efficiency. Compared with the traditional ice-making machine, the high-efficiency and energy-saving de-icing component 2 makes the ice-making process more efficient, that is, multiple parts are involved in ice-making, thereby improving the ice-making speed.

[0061] In addition, this ice-making method has other advantages. The increased contact area means that more ice can be produced under the same energy consumption. Therefore, the efficient and energy-saving ice-removing component 2 can meet the demand for ice cubes more quickly, reduce waiting time, and improve overall operational efficiency.

[0062] When the evaporator 12 switches from cooling to heating, the evaporator 12 electrically controls the ice storage bin 15 to start, and the ice cubes attached to the evaporation tube 121 and the high-efficiency and energy-saving ice removal component 2 begin to melt. Since the striped protrusions 21 are inclined, the ice cubes will obtain a downward component force, which is the initial driving force for the ice cubes to start moving downward. At the same time, after the ice point inside the friction depressions 22 melts into water, a lubricating layer is formed on the surface of the ice cubes and the striped protrusions 21. This lubricating effect greatly reduces the friction of the ice cubes when they move, and the water film formed by this part of the melted water attached to the surface of the striped protrusions 21 can isolate part of the heat, thereby preventing the evaporation tube 121 from excessively melting the ice cubes, and ensuring that the ice cubes continue to move downward in a suitable state.

[0063] Under the guidance of the striped protrusions 21 and the lubrication of the friction dimples 22, the ice cube rotates and descends along the trajectory of the striped protrusions 21. During this process, the ice flakes inside the acceleration fins 24 collide with the bottom of the acceleration fins 24 as the ice cube moves, causing the ice flakes to break. The broken ice flakes move with the ice cube as a whole under their own gravity, the lubrication generated by the melting of the ice point inside the friction dimples 22, and the guidance of the striped protrusions 21. When the broken ice flakes impact the ice cube, the ice cube gains a small amount of kinetic energy. This process is very critical because after the broken ice flakes are pressed downward by the ice cube, the ice cube is mainly heated, thereby effectively preventing the ice cube itself from being continuously heated by the evaporation tube 121, thereby ensuring the integrity and solid structure of the ice cube.

[0064] In addition, since the surface of the striped protrusion 21 is provided with a microchannel 25, and its cross-sectional area gradually decreases, when the ice cube moves on the surface of the striped protrusion 21, the shape of the microchannel 25 makes the component of the supporting force on the ice cube in the direction perpendicular to the surface of the striped protrusion 21 gradually decrease. According to Newton's second law, the resultant force on the ice cube in the horizontal direction increases, and the acceleration also increases accordingly. At the same time, the dovetail groove 23 ensures the stable movement of the ice cube and prevents it from vibrating and losing kinetic energy. Under normal circumstances, the ice cube is only affected by gravity when it falls naturally, and the acceleration is the gravitational acceleration g. In the present invention, in addition to gravity, the ice cube is also affected by the inclination of the striped protrusion 21. Due to the combined influence of various factors such as the component force brought by the friction pits 22, the acceleration effect brought by the lubrication of the melted water to reduce the friction, the increase in kinetic energy brought by the impact of the broken ice flakes, the increase in the horizontal force brought by the microchannel 25 structure, and the dovetail groove 23 stabilizing structure to prevent kinetic energy loss, this design makes the ice cubes fall slightly faster than normal natural fall. Therefore, the high-efficiency and energy-saving ice-removing component 2 reduces the risk of ice cubes being overheated and melted on the surface of the evaporator tube 121, thereby improving the quality of the ice cubes and ensuring that the ice cubes are collected in a better solid form. Secondly, the rapid descent can improve the overall working efficiency of the ice maker and shorten the ice-making cycle.

[0065] The fallen ice cubes will fall onto the inner wall of the machine body 11 and will be pushed into the ice storage bin 15 by the ice shovel when the ice storage bin 15 is restarted.

[0066] It should be noted that, under the guidance of the striped protrusions 21, the ice cube will form a concave groove on one side of the evaporation tube 121, and the ice cube with the groove is less likely to melt than the ice cube without the groove.

[0067] According to the principle of heat conduction, the thermal conductivity of the air in the groove is much lower than that of ice. When heat tries to transfer into the ice, the air in the groove hinders the rapid transfer of heat. Moreover, due to the existence of the groove, the heat transfer path on the surface of the ice becomes more complicated, and it cannot directly penetrate into the interior of the ice like on a flat surface, thereby slowing down the melting rate.

[0068] At the same time, when this kind of ice cube is put into a drink, the groove increases the contact area between the ice cube and the drink. According to the principle of heat exchange, the rate of heat exchange is proportional to the contact area, that is, an increase in the contact area means an increase in the flux of heat exchange.

[0069] Therefore, grooved ice cubes can absorb heat from the beverage more quickly, causing the beverage temperature to drop faster. The presence of the grooves allows the ice cubes to form more cooling "cores" in the beverage. The temperature of the beverage around these "cores" will drop rapidly, and then diffuse the low temperature throughout the beverage through convection, further improving the refrigeration efficiency.

[0070] Embodiment 2: Figure 1 and Figure 2 as well as Figure 8 and Fig. 9 As shown, on the basis of the first embodiment, a non-powered cold air circulation component 3 for improving the ice storage capacity by circulating cold air is arranged below the movable end of the body 11, and the non-powered cold air circulation component 3 includes a plurality of input bins 31, and the plurality of input bins 31 are all arranged in a rectangular shape and are fixedly connected to the four corners of the inner wall of the ice storage bin 15 at equal intervals. The top of the ice storage bin 15 is symmetrically fixedly connected to an output bin 32, and circulation channels 33 are provided on the inner walls on both sides of the ice storage bin 15. The circulation channels 33 are respectively connected to the input bin 31 and the output bin 32, and the inner wall of the circulation channel 33 and its vertical end are linearly and equidistantly arranged and fixedly connected to a plurality of guide plates 34.

[0071] like Figure 8 and Fig. 9 As shown, the outer surfaces of the input bin 31 and the output bin 32 are both installed with filter screens, and the guide plates 34 are all inclined, and the inclination angle increases gradually from bottom to top, so that the space inside the circulation channel 33 is continuously reduced.

[0072] like Figure 8 and Fig.10As shown, the unpowered cold air circulation component 3 also includes two placement shells 35, which are symmetrically installed on the inner surface of the ice storage bin 15. Water-absorbent cotton cloth 36 is installed inside the placement shells 35. A first rectangular groove is opened on one side of the placement shells 35 close to the inner surface of the ice storage bin 15, and a plurality of first heat exchange plates 37 are installed inside the first rectangular groove.

[0073] The body 11 is linearly and equidistantly arranged and symmetrically penetrated with a plurality of second rectangular grooves, each of which is equipped with a second heat exchange plate 38. The outer surface of the body 11 and the center point of the second heat exchange plate 38 are fixedly connected with a plurality of air scoops 39.

[0074] It should be noted that the side of the wind scoop 39 away from the second heat exchanger fin 38 gradually increases, the absorbent cotton cloth 36 is made of a water-absorbent material, specifically glass fiber cotton, and the surfaces of the first heat exchanger fin 37 and the second heat exchanger fin 38 are coated with a hydrophobic coating.

[0075] Specifically, after the ice cubes fall into the ice storage bin 15, as the ice cubes continue to accumulate, the space in which the cold air can move gradually decreases due to its natural sinking characteristics. At this time, since the input bin 31 is distributed in a rectangular shape at the four corners of the inner wall of the ice storage bin 15, its protruding structure provides a flow channel for the cold air when a large amount of ice cubes accumulate or even get blocked. Based on the principle of fluid continuity, when the mainstream channel of the cold air in the gaps between the ice cubes is blocked, it will look for other passable paths, and the space occupied by the input bin 31 becomes a "bypass" for the cold air, allowing the cold air to continue to flow.

[0076] Then, the cold air inside the circulation channel 33, which is continuously displaced by the subsequent cold air, begins to move slowly upward. Since the guide plates 34 are all inclined and their inclination angles gradually increase from bottom to top, this design causes the space inside the circulation channel 33 to continuously decrease. According to Bernoulli's principle, in an incompressible ideal fluid, when the flow rate increases, the static pressure of the fluid will decrease. When the cold air passes through the gradually narrowing space, its flow rate will continue to increase. This acceleration effect enables the cold air to move upward more effectively, and finally enters the output bin 32 through the circulation channel 33 and is discharged to the surface of the ice above, thereby realizing unpowered cold air circulation.

[0077] In this process, since the absorbent cotton cloth 36 is made of absorbent material and is connected to the circulation channel 33, and based on the water absorption characteristics of the absorbent cotton cloth 36 and its internal capillary structure, when the cold air flows through the circulation channel 33, the absorbent cotton cloth 36 can absorb part of the water vapor in the cold air. In the capillary structure, the liquid will rise or be absorbed in the small pipe due to the effect of surface tension. After the absorbent cotton cloth 36 absorbs the water vapor, it can prevent the water vapor from condensing into an ice layer while maintaining a low temperature, thereby preventing the water vapor from condensing into ice in a low temperature environment, and preventing the water vapor from gradually forming an ice layer inside the equipment, thereby preventing the ice storage efficiency from decreasing.

[0078] In addition, when the ice storage bin 15 is installed inside the machine body 11, the first heat exchanger fin 37 is in contact with the second heat exchanger fin 38, and the two can be regarded as a whole. One end of the whole is in contact with the absorbent cotton cloth 36, and the other end is in contact with the outside world. There is a wind scoop 39 at the end of the whole facing the outside world, and at the same time, the side of the wind scoop 39 away from the second heat exchanger fin 38 gradually increases. When the outside hot air approaches this structure, the side with a large opening of the wind scoop 39 faces the outside world, and the small side faces this whole. According to the gas diffusion principle, the outside hot air will be blocked when trying to enter. At the same time, the outside hot air and When this whole is in contact, it will continuously absorb cold air. According to the second law of thermodynamics, heat is always transferred from a high-temperature object to a low-temperature object. The temperature of the external hot air is higher than the temperature of the cold air in the ice storage bin 15. During the contact process, the special structure of the wind scoop 39 prevents large-scale backflow of external hot air, and only a small amount of heat exchange occurs at the contact interface. The result of this heat exchange is that the temperature of the external hot air decreases and the temperature of the cold air increases slightly, but the overall temperature of the cold air in the ice storage bin 15 is still at a relatively low level, which helps to improve the storage stability of ice cubes and reduce the melting rate of ice cubes.

[0079] Therefore, in this environment, ice can remain solid for a longer period of time, reducing the energy loss and degradation of ice quality caused by melting and refreezing of ice due to temperature changes. At the same time, this unpowered cold air circulation system does not require additional energy input, which is in line with the design concept of energy saving and high efficiency.

[0080] It should be noted that the absorbent cotton cloth 36 is installed inside the placement shell 35, that is, when the absorbent cotton cloth 36 reaches the limit of use, the user can replace it by himself.
