In the related art, some storage equipment such as refrigerators and drinking water equipment have ice making function, but the ice cubes made in the above equipment have low transparency due to the existence of bubbles and other impurities.

[0065] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are exemplary only, and are not intended to limit the present application.

[0066] The ice-making device, the storage equipment and the water dispenser according to the embodiments of the present application are described below with reference to Figs. 1-10.

[0067] It should be noted that the storage equipment in the present embodiment can be understood as a general refrigeration storage equipment, including but not limited to a refrigerator, a freezer, a display cabinet, a beverage cabinet, a wine cabinet, a cold fresh cabinet and a refrigeration vending machine, etc. having an ice-making function, and the storage equipment has various structural forms and a wide range of applications.

[0068] The water dispenser in the present embodiment can be understood as a general refrigeration water dispenser, and the water dispenser is used for extracting purified water or making ice. The ice generated by the ice-making device or the ice generated and stored by the ice-making device is transferred to the water dispenser, and the user can obtain the ice from the water dispenser. The water dispenser includes but is not limited to a direct drinking machine, a pipeline machine, a table-type heat purification integrated machine, a tea bar machine and an instant heating water purifier, etc. having an ice-making function, and is a household water dispenser or a commercial water dispenser.

[0069] The ice-making device can be a small electric appliance for making ice alone, or can be an ice-making module of the storage equipment or the water dispenser.

[0070] As shown in Fig. 1, the ice-making device according to the present embodiment includes an ice-making container 2, a cold source 4 and an energy emission source 5.

[0071] The ice-making container 2 forms at least one containing cavity 21 for making ice; the cold source 4 is used for supplying cold to the containing cavity 21; and the energy emission source 5 is used for outputting energy radiation to the containing cavity 21.

[0072] The energy emitting source 5 can be a light source, an infrared emitter, a heating device, an ultrasonic wave emitting source, or a microwave source.

[0073] For example, the energy emitting source 5 can be installed in the inner container, or the energy emitting source 5 can be installed in the ice making container 2, or the energy emitting source 5 can be partially installed in the inner container and partially installed in the ice making container 2.

[0074] The ice making container 2 forms at least one containing cavity 21, for example, the number of containing cavities 21 can be 1, 3, 6, 10, 20, or more, and the containing cavity 21 is the main place for ice making, and one containing cavity 21 can make one ice block. During the freezing process, the liquid medium 6 such as water, juice, tea, beverage, etc. is injected into the containing cavity 21, and then cooled by the cold provided by the cold source 4, and finally solidified into ice.

[0075] The liquid medium 6 contains various impurities, such as fruit particles, tea leaves, or air bubbles, etc. Among them, air bubbles are the main factor affecting the transparency of ice.

[0076] The containing cavity 21 can be spherical, cubic, or other irregular shape combinations. When the containing cavity 21 is spherical, the ice making device can make spherical ice blocks, and when the containing cavity 21 is cubic, the ice making device can make cubic ice blocks. The volume of the containing cavity 21 can be 20ml, 35ml, or 50ml, or different volumes of containing cavities 21 are combined to meet the needs of different ice using scenarios.

[0077] The liquid medium 6 needs to go through a cooling stage, a crystallization stage, and a freezing stage during the freezing process. The temperature of the liquid medium 6 gradually decreases to the freezing point in the cooling stage. In the crystallization stage, the liquid gradually freezes to solid. In the freezing stage, the water content in the ice block gradually decreases to zero, and the hardness of the ice block increases.

[0078] The cold source 4 can be a refrigeration system of a storage device or a water dispenser, or the cold source 4 can be a refrigeration device owned by the ice making device, such as a semiconductor refrigeration sheet.

[0079] The cold source 4 provides cold to the liquid medium 6 in the containing cavity 21. The refrigeration system can be directly connected to the ice making container 2, and the cold air of the refrigeration system is forced to flow to provide cold air to the containing cavity 21. Alternatively, the ice making device is placed in the freezing compartment of the storage device, and the cold air in the freezing compartment provides cold to the containing cavity 21 by natural convection. Alternatively, the semiconductor refrigeration sheet directly exchanges heat with the ice making container 2 to provide cold to the containing cavity 21.

[0080] In the case that the ice making device can make ice independently, the cold source 4 can be a refrigeration device owned by the ice making device; in the case that the ice making device needs to be placed in the refrigeration compartment of the storage device to make ice, the ice making device can directly or indirectly use the cold energy of the storage device to make ice.

[0081] In the case that the energy emitting source 5 is a light source, the energy emitting source 5 can be visible light or invisible light with a certain wavelength, the light can change the surface tension of the ice-water interface, the light uses various optical effects to change the surface tension of the ice-water interface, for example, photo-thermal effect, most of the energy radiation output by the energy emitting source 5 passes through the liquid medium 6 and is incident on the ice-water interface, the ice-water interface absorbs light energy and the temperature rises under the irradiation of the energy radiation, and this temperature change can reduce the surface tension of the ice-water interface, thereby effectively reducing the adsorption force of the ice-water interface to the bubbles.

[0082] Since the energy emitting source 5 generates heat when working, the temperature inside the containing cavity 21 is higher closer to the energy emitting source 5, and therefore the position closer to the energy emitting source 5 in the containing cavity 21 freezes later. As the ice grows, the ice-water interface gradually approaches the position of the energy emitting source 5, and in the process of the ice-water interface approaching the energy emitting source 5, the energy radiation generated by the energy emitting source 5 can always pass through the unfrozen liquid medium 6 and be incident on the ice-water interface, so that the energy radiation can continuously reduce the surface tension of the newly generated ice-water interface. During the freezing process of the liquid medium 6 in the containing cavity 21, the air dissolved in the liquid medium 6 will continuously precipitate to form bubbles, and since the adsorption force of the ice-water interface is reduced under the action of the energy radiation, the amount of bubbles adsorbed on the ice-water interface is significantly reduced, and the free bubbles will be gradually expelled by the ice layer to the unfrozen area close to the energy emitting source 5, and then escape from the liquid medium 6, thereby significantly improving the transparency of the frozen ice block.

[0083] The positions of the energy emitting source 5 and the cold source 4 can be set according to actual conditions, for example, the energy emitting source 5 and the cold source 4 can be arranged oppositely, or the energy emitting source 5 and the cold source 4 can be arranged at a certain angle; or the cold source 4 is arranged at the center of the containing cavity 21, the ice making container 2 is transparent and placed in a light chamber, and the peripheral wall of the ice making container 2 can receive the energy radiation output by the energy emitting source 5.

[0084] For example, the energy emitting source 5 can be a light source, and the light source can be one or more light beads combined, so that the number of light beads can be adapted according to the required radiation intensity to adapt to various working scenarios.

[0085] As shown in FIG. 5 and FIG. 6, the ice making device comprises a thermal insulation layer 3, an ice making container 2 and a cold source 4, at least part of the wall of the ice making container 2 is not covered by the thermal insulation layer 3, the wall of the ice making container 2 not covered by the thermal insulation layer 3 exchanges heat with the cold source 4 to form a cooling section 22, the liquid medium in the containing cavity 21 is oriented to freeze layer by layer from the position close to the cooling section 22 to the position away from the cooling section 22, along the direction from the position close to the cooling section 22 to the position away from the cooling section 22, the ice strip, the ice crystal strip and the liquid medium strip are formed layer by layer in the containing cavity 21, the liquid medium solidifies to form the solid ice strip in the temperature zone less than -3℃, the liquid medium is in the ice water mixed state in the temperature zone between -3℃ and 0℃, and the liquid medium is in the liquid state in the temperature zone greater than 0℃, when the bubbles float through the ice crystal strip, the ice water interface of the solid ice in the ice crystal strip will have adsorption force to the bubbles, and part of the bubbles are adsorbed to the surface of the solid ice. Among them, the ice crystal strip can be divided according to the temperature and different ice water ratios in different temperature zones, for example, the first ice crystal layer with the most ice content in the temperature zone between -3℃ and -2℃, the second ice crystal layer with moderate ice content in the temperature zone between -2℃ and -1℃, and the third ice crystal layer with the least ice content in the temperature zone between -1℃ and 0℃. The arrow direction in the figure represents the rising trend of the temperature.

[0086] FIG. 5 shows the first embodiment provided with the energy emitting source 5, in the embodiment, the energy emitting source 5 is arranged opposite to the cold source 4 to form the structure that the energy emitting source 5 is above the cold source 4, the energy emitted by the energy emitting source 5 radiates on the newly generated ice water interface and also radiates on the ice water interface of the surface of the solid ice in the ice crystal strip, under the action of the energy radiation, the surface tension of the ice water interface is reduced, and the bubbles adsorbed on the ice water interface escape; at the same time, since the energy emitting source 5 outputs heat while working, the temperature of the area close to the energy emitting source 5 rises, the total thickness of the ice crystal layer in the temperature zone between -3℃ and 0℃ in the containing cavity 21 becomes smaller, that is, the thickness of the first ice crystal layer between -3℃ and -2℃, the second ice crystal layer between -2℃ and -1℃ and the third ice crystal layer between -1℃ and 0℃ all become smaller, the total thickness of the ice crystal strip becomes smaller, the total number of the solid ice in the ice crystal strip is reduced, the probability of the bubbles being adsorbed by the solid ice in the process of floating is reduced, and the bubbles have less escaping resistance, so that the number of the frozen bubbles can be reduced, and the transparency of the ice block can be improved. The temperature change in the figure is shown by the arrow, the farther away from the cold source 4, the higher the temperature, and the area of the region with higher temperature gradually increases.

[0087] Figure 6 shows a comparative example without the energy emitting source 5, in this embodiment, the temperature of the area close to the ice band is low, the total thickness of the ice crystal layer in the -3℃ to 0℃ temperature zone in the containing cavity 21 is large, i.e. the thickness of the first ice crystal layer in the -3℃ to -2℃ temperature zone, the second ice crystal layer in the -2℃ to -1℃ temperature zone and the third ice crystal layer in the -1℃ to 0℃ temperature zone are all large, the total thickness of the ice crystal band is large, which leads to an increase in the total amount of solid ice in the ice crystal band, an increase in the probability of the bubbles being adsorbed by the solid ice during the bubble floating process, an increase in the bubble floating escape resistance, and thus an increase in the number of bubbles frozen in the ice band, which affects the transparency of the ice block. In the figure, the temperature change is shown by arrows, the temperature of the area farther away from the cold source 4 is higher, and the temperature changes linearly.

[0088] In some embodiments, as shown in Figure 7, Figure 7 shows embodiment two with only the energy emitting source 5 and the cold source 4, the containing cavity 21 is not provided with the heat preservation layer 3, the wall surface of the containing cavity 21 forms the cooling section 22, in comparison with the case where the containing cavity 21 is provided with the heat preservation layer, the wall surface of the containing cavity 21 in this embodiment forms the cooling section 22 as a whole, the cold source 4 cools the wall surface of the containing cavity 21 to make the liquid medium freeze layer by layer from the position close to the cooling section 22 to the position far away from the cooling section 22, i.e. the ice layer grows from the outside to the inside, and the ice layer extends around the circumference of the containing cavity 21. The energy radiation emitted by the energy emitting source 5 irradiates the spherical newly formed ice-water interface within the irradiation angle, and also irradiates the ice-water interface on the surface of the solid ice in the ice crystal band, under the action of the energy radiation, the surface tension of the ice-water interface within the irradiation angle is reduced, and the bubbles adsorbed on the ice-water interface escape; at the same time, since the energy emitting source 5 outputs heat while working, the temperature of the area close to the energy emitting source 5 is increased, the ice-water interface not irradiated by the energy radiation will be affected by the heat radiation to cause the surface tension to be reduced, and the bubbles adsorbed on the ice-water interface escape; the total thickness of the ice crystal layer in the -3℃ to 0℃ temperature zone in the containing cavity 21 is small, i.e. the thickness of the first ice crystal layer in the -3℃ to -2℃ temperature zone, the second ice crystal layer in the -2℃ to -1℃ temperature zone and the third ice crystal layer in the -1℃ to 0℃ temperature zone are all small, the total thickness of the ice crystal band is small, which leads to a decrease in the total amount of solid ice in the ice crystal band, a decrease in the probability of the bubbles being adsorbed by the solid ice during the bubble floating process, and a smaller bubble floating escape resistance, so as to reduce the number of frozen bubbles and improve the transparency of the ice block. In the figure, the temperature change is shown by arrows, the temperature of the area farther away from the cold source 4 is higher, and the area of the higher temperature zone gradually increases.

[0089] In summary, the comparison between the comparative example and embodiment one shows that the setting of the energy emitting source 5 can significantly reduce the bubble content in the ice block and improve the transparency of the ice block; the comparison between the comparative example and embodiment two shows that the setting of the heat preservation layer can increase the effect of directional ice formation of the ice layer and improve the transparency of the ice block. In order to improve the transparency of the ice block, many ice making devices have also been designed, but they have not better solved the problem of improving the transparency of the ice, for example:

[0090] Related technology one, the ice making device is provided with a pneumatic stirring degassing device and an ultrasonic vibration degassing device, a compressed air supply system provides compressed air to each group of ice molds to blow out gas, and air bubbles float out in the ice grid, taking out the air in the water; the ultrasonic vibration degassing device can promote the escape of the remaining air bubbles at the top of the water body by vibrating the upper part of the water body, thereby improving the transparency of the top of the ice block. However, in the above crystallization process, the gas blowing system into the ice mold will cause a large amount of gas to participate in the freezing, resulting in a large number of air bubbles remaining in the liquid medium, and it is difficult to completely remove the gas at the ice-water interface by ultrasonic vibration degassing. Through theoretical analysis and experimental demonstration, the transparency of the ice block obtained by this method is still not high.

[0091] Related technology two, the ice making device is provided with a cold source and an ice grid placed in a heat preservation layer, the top of the heat preservation layer is open, and the cold source is placed at the top opening of the heat preservation layer. The cold source provides cooling for the liquid medium in the ice grid to freeze the liquid medium layer by layer from top to bottom so as to squeeze the impurities in the liquid medium to the bottom of the ice grid without being frozen in the middle of the ice block. However, in the above crystallization process, since the ice-water interface has adsorption force on the air bubbles, and the air bubbles have buoyancy relative to the liquid medium, the air bubbles will actually float to the ice-water interface and be adsorbed there. In the process of layer-by-layer freezing of the liquid medium, the air bubbles are frozen in the ice layer, resulting in air bubbles in the ice block and reducing the transparency of the ice block. It does not solve the problem of ice block transparency well.

[0092] Related technology three, the ice making device includes an ice chamber and a lower heater, the lower heater provides heat to the lower chamber during the freezing process, so that the ice in the ice chamber starts to freeze from top to bottom. In the crystallization stage, the air bubbles in the ice chamber move from top to bottom, and when the ice making is completed, the lowermost part of the spherical ice is white. In the above crystallization process, the directional freezing from top to bottom causes the air bubbles to collect on the lower side, but the air bubbles float to the ice-water interface due to the buoyancy and are adsorbed there. In the process of layer-by-layer freezing of the water, the air bubbles are frozen in the ice layer, and there are air bubbles in the ice block, and the lowermost part of the ice block has more air bubbles and is white. The transparency of the ice block obtained by this method is still not high.

[0093] Related technology four, the ice making device includes an ice making mold and a heating mechanism, the top of the ice making mold is in contact with a low-temperature space to receive cold, and the bottom of the ice making mold is provided with a heating element, a water storage box and an exhaust part. In the process of ice making, the liquid medium freezes layer by layer from top to bottom, and the air bubbles are pushed downward to the water storage cavity. The scheme of related technology four is essentially the same as that of related technology three, both of which collect air bubbles in the liquid medium towards the unfrozen area by heating the liquid medium to improve the transparency of the ice block. In related technology four, the problem of air bubbles being adsorbed at the ice-water interface due to the buoyancy of the air bubbles and the adsorption force of the ice-water interface still exists, and in the process of layer-by-layer freezing of the water, the air bubbles are frozen in the ice layer, affecting the transparency of the ice block. It does not solve the problem of ice block transparency well.

[0094] In contrast, the ice-making device provided by the present application can significantly reduce the number of bubbles adsorbed on the ice-water interface by changing the adsorption force of the ice-water interface through the radiation generated by the energy emitting source 5; and can protect the energy emitting source 5 and improve safety by limiting the distance between the energy emitting source 5 and the liquid medium 6. In the case of a light source as the energy emitting source 5, the surface tension can be controlled by light, and the adsorption force of the ice-water interface can be changed by the energy radiation generated by the energy emitting source 5, thereby significantly reducing the number of bubbles adsorbed on the ice-water interface. As the ice in the containing cavity 21 grows, the ice-water interface gradually approaches the position of the energy emitting source 5. In the process of the ice-water interface approaching the energy emitting source 5, the energy radiation generated by the energy emitting source 5 can always irradiate the ice-water interface through the unfrozen liquid medium 6, so that the energy radiation can continuously reduce the surface tension of the newly formed ice-water interface. Due to the reduction of the adsorption force of the ice-water interface under the action of the energy radiation, the number of bubbles adsorbed on the ice-water interface is significantly reduced, the transparency of the ice layer is significantly improved, and the bubbles are gradually squeezed out of the ice layer to the unfrozen area near the energy emitting source 5, and then escape from the liquid medium 6, thereby significantly improving the transparency of the frozen ice block.

[0095] According to the ice-making device provided by the embodiment of the present application, the cold source 4 and the energy emitting source 5 are arranged, the energy emitting source 5 can reduce the surface tension of the ice-water interface by outputting energy radiation, thereby reducing the bubbles attached to the ice-water interface, and the cold source 4 can provide cold to the liquid medium 6 in the containing cavity 21 to make the liquid medium 6 freeze layer by layer, so that the bubbles are continuously squeezed out by the ice layer, and then gradually gather to the last frozen part of the containing cavity 21 until escaping from the liquid medium 6 without being frozen in the middle of the ice, thereby improving the overall transparency of the ice block, improving the aesthetic appearance of the ice block, prolonging the melting time of the ice block, reducing the melting rate of the ice block, and improving the ice cooling effect.

[0096] In some embodiments, as shown in FIG. 1, the heat transfer direction of the cold source 4 is arranged opposite to the irradiation direction of the energy radiation output by the energy emitting source 5.

[0097] In the embodiment, the heat transfer region of the cold source 4 is substantially a fan shape, and the heat transfer direction of the cold source 4 is the central axis direction of the fan shape; the irradiation region of the energy radiation output by the energy emitting source 5 is also substantially a fan shape, and the irradiation direction of the energy radiation output by the energy emitting source 5 is the central axis direction of the fan shape.

[0098] In the embodiment, the cold source 4 and the energy emitting source 5 are arranged opposite to each other on the two sides of the ice-making container 2.

[0099] Exemplarily, when the accommodating cavity 21 is spherical, the cold source 4 and the energy emitting source 5 are oppositely arranged at two sides of the accommodating cavity 21 along a radial direction of the ice making container 2; when the accommodating cavity 21 is axisymmetric, the cold source 4 and the energy emitting source 5 are oppositely arranged at two sides of the accommodating cavity 21 along an axis of symmetry of the ice making container 2.

[0100] Exemplarily, the energy emitting source 5 and the cold source 4 can be arranged at upper and lower sides of the accommodating cavity 21 along a vertical direction; or the energy emitting source 5 and the cold source 4 can be arranged at left and right sides of the accommodating cavity 21 along a horizontal direction; or the energy emitting source 5 and the cold source 4 can be arranged at two sides of the accommodating cavity 21 along an inclined direction.

[0101] In the embodiment, by oppositely arranging the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5, oppositely arranging the ice growth direction in the accommodating cavity 21 and the irradiation direction of the energy radiation, and oppositely arranging the irradiation area of the energy radiation and the heat transfer area of the cold source 4, the area of the energy radiation irradiated on the ice-water interface can be increased, and the energy radiation generated by the energy emitting source 5 can be more uniformly irradiated on the ice-water interface, the ice-water interface can be subjected to more uniform radiation intensity, the surface tension difference of the ice-water interface is smaller, and the transparency of the ice block is better.

[0102] It can be understood that if the energy emitting source 5 is not oppositely arranged with the cold source 4, the irradiation area generated by the energy emitting source 5 is inclined relative to the heat transfer direction of the cold source 4, and the ice-water interface can be only partially irradiated by the energy emitting source 5. If the energy radiation output by the energy emitting source 5 cannot be uniformly irradiated on the ice-water interface, the area of the ice-water interface subjected to stronger energy radiation has smaller tension and weaker adsorption, the number of adsorbed bubbles is small, the transparency of the ice block is higher, but the ice growth rate is slow; the area of the ice-water interface subjected to weaker energy radiation has larger tension and stronger adsorption, the number of adsorbed bubbles is large, the transparency of the ice block is lower, but the ice growth rate is fast, and with the continuation of the ice forming process, the ice block can have a situation that one side has more bubbles and lower transparency, and the other side has fewer bubbles and higher transparency. Therefore, oppositely arranging the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 can make the energy radiation generated by the energy emitting source 5 more uniformly irradiated on the ice-water interface, the energy radiation intensity difference of the ice-water interface is smaller, and the adsorption of bubbles can be effectively reduced in each area of the ice-water interface, and the transparency of the ice block is improved.

[0103] In some embodiments, the energy emitting source 5 is configured to output energy radiation to the accommodating cavity 21 from a first side of the ice making container 2, and the cold source 4 is configured to supply cold to the accommodating cavity 21 from a second side of the ice making container 2, the first side being oppositely arranged with the second side.

[0104] The first side of the ice making container 2 is arranged opposite to the second side of the ice making container 2, for example, the first side and the second side can be the upper and lower sides of the ice making container 2 in the vertical direction, the first side and the second side can be the left and right sides of the ice making container 2 in the horizontal direction, or the first side and the second side can be the opposite sides of the ice making container 2 in the inclined direction.

[0105] In the embodiment, the energy emitting source 5 and the cold source 4 are arranged on the opposite sides of the ice making container 2, and the energy emitting source 5 and the cold source 4 can be arranged opposite to each other or offset relative to each other.

[0106] In some embodiments, the vector included angle between the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 is 180±10°.

[0107] In some embodiments, the vector included angle between the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 satisfies [170, 190], for example, the vector included angle between the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 is 175°, 180° or 185°. In other words, the heat transfer direction of the cold source 4 is arranged opposite to the irradiation direction of the energy radiation output by the energy emitting source 5 or offset relative to each other by a small angle, so that the energy radiation generated by the energy emitting source 5 can be uniformly irradiated on the ice-water interface, the energy radiation intensity received by the ice-water interface is small, and the ice-water interface can effectively reduce the adsorption force on the bubbles, thereby improving the transparency of the ice block.

[0108] For example, the vector included angle between the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 is 180°, that is, the heat transfer direction of the cold source 4 is arranged opposite to the irradiation direction of the energy radiation output by the energy emitting source 5.

[0109] In some embodiments, the energy emitting source 5 is configured to output energy radiation from the first side of the ice making container 2 to the containing cavity 21, the wall surface of the ice making container 2 has at least one cooling section 22, and the cold source 4 is configured to supply cold to the outer wall of the cooling section 22, and the cooling section 22 is arranged opposite to the first side.

[0110] The liquid medium 6 in the containing cavity 21 exchanges heat with the cold source 4 through the cooling section 22. In the case that the ice making device is directly connected to the refrigeration system, the cooling section 22 faces the cold air outlet of the refrigeration system, and the refrigeration system directly provides cold to the cooling section 22. In the case that the ice making device is placed in the refrigeration compartment of the storage equipment, the cold in the refrigeration compartment contacts the cooling section 22 to provide cold to the containing cavity 21. In the case that the cold source 4 is a semiconductor refrigeration sheet or other refrigeration device, the semiconductor refrigeration sheet or other refrigeration device can be attached to the cooling section 22 to directly provide cold to the containing cavity 21.

[0111] In the case that the accommodating cavity 21 is spherical, the cooling section 22 can be at least one arc-shaped surface or at least one strip-shaped arc segment arranged opposite to the first side; in the case that the accommodating cavity 21 is cubic, the cooling section 22 can be at least one plane or at least one strip segment arranged opposite to the first side.

[0112] The cooling section 22 can be one continuous surface, or multiple surfaces arranged at intervals, or one continuous strip-shaped segment or multiple strip-shaped segments arranged at intervals.

[0113] In some embodiments, the cooling section 22 includes multiple cooling sections symmetrically arranged on both sides of the target axis, and the angle between the axis of the energy emitting source 5 and the target axis is α, which satisfies: α≤5°.

[0114] In the above formula, the axis of the energy emitting source 5 is the central axis of the irradiation area of the energy radiation output by the energy emitting source 5, and the angle α between the axis of the energy emitting source 5 and the target axis can be 0°, 2°, 4° or 5°.

[0115] For example, the axis of the energy emitting source 5 can coincide with the target axis, the angle α between the axis of the energy emitting source 5 and the target axis is 0°, and the cooling section 22 is symmetrically arranged on both sides of the target axis, i.e., the cooling section 22 is symmetrically arranged on both sides of the axis direction of the energy emitting source 5, the energy emitting source 5 and the cold source 4 are arranged opposite to each other, and the cold source 4 provides cold energy to freeze the liquid medium 6 opposite to the energy emitting source 5. The new ice-water interface is symmetrically located on both sides of the axis direction of the energy emitting source 5, so that the energy radiation generated by the energy emitting source 5 can uniformly irradiate the ice-water interface, the energy radiation intensity difference of the ice-water interface is small, and the ice block has high transparency.

[0116] In some embodiments, as shown in FIG. 1, the energy emitting source 5 is installed above the accommodating cavity 21, and the cold source 4 is used to supply cold energy to the lower wall surface of the accommodating cavity 21.

[0117] In the present embodiment, the energy emitting source 5 can be arranged at intervals above the accommodating cavity 21, or can be installed in the accommodating cavity 21, the energy radiation output by the energy emitting source 5 irradiates from above the accommodating cavity 21 towards the lower wall surface of the accommodating cavity 21, and the heat transfer direction of the cold source 4 is from the lower wall surface of the accommodating cavity 21 towards the upper portion of the accommodating cavity 21, i.e., the energy emitting source 5 is arranged above the cold source 4.

[0118] In the related art II, the cold source is arranged above the ice tray, although the directional ice making can expel the bubbles in the water to the lower portion of the ice tray, due to the bubble buoyancy and the adsorption of the ice-water interface, the bubbles will inevitably rise to the ice-water interface and be adsorbed to the ice-water interface, so the transparency of the ice block obtained by using this method is still not high.

[0119] In the related art three and the related art four, the arrangement mode of cold source on the top and heat source on the bottom is adopted, and in the crystallization process, the directional freezing from top to bottom causes the bubbles to gather on the bottom side, but the bubbles are adsorbed on the ice-water interface due to the buoyancy, and in the process of water layer-by-layer freezing, the bubbles are still frozen in the ice layer, and the ice block obtained is white at the lowermost end, and the transparency of the ice block obtained by this mode is still not high.

[0120] Compared with the above, the arrangement mode of cold on the top and heat on the bottom is adopted, the energy emitting source 5 is arranged above the containing cavity 21, and the cold source 4 is arranged below the containing cavity 21, and in the freezing process, the directional freezing from bottom to top causes the bubbles to gather upwards, and the bubbles are more easily gathered towards the region where the energy emitting source 5 is located due to the buoyancy, which further reduces the amount of bubbles on the ice-water interface and significantly improves the transparency of the ice block.

[0121] In the embodiment, the arrangement mode of energy emitting source 5 on the top and cold source 4 on the bottom is adopted, because the air density is smaller than the water, the bubbles are more easily discharged from bottom to top due to the buoyancy, and the cold source 4 is arranged on the bottom, and in the process of ice growing towards the top, the bubbles are more easily gradually expelled to the un-frozen region on the top near the energy emitting source 5; and the surface tension of the ice-water interface can be reduced by energy radiation, thereby effectively reducing the adsorption force of the ice-water interface on the bubbles, and the amount of bubbles adsorbed on the ice-water interface can be significantly reduced, and the transparency of the ice block can be significantly improved under the double effects of water escaping from bottom to top due to the buoyancy and the reduced adsorption force of the ice-water interface on the bubbles.

[0122] In some embodiments, the energy emitting source 5 is adapted to be located above the liquid surface of the containing cavity 21, and the energy emitting source 5 is spaced apart from the liquid surface.

[0123] In the embodiment, the energy emitting source 5 is located above the liquid surface, and the energy emitting source 5 is spaced apart from the liquid surface by a certain distance, that is, there is an air cavity between the energy emitting source 5 and the liquid surface, or a light-transmitting plate is arranged between the energy emitting source 5 and the liquid surface, so as to avoid the contact between the energy emitting source 5 and the liquid medium 6, which can improve the safety and hygiene of the obtained ice block, and can also protect the energy emitting source 5 and prolong the service life thereof.

[0124] In the case that there is an air cavity between the energy emitting source 5 and the liquid surface, in the process of ice growing towards the energy emitting source 5, the bubbles are gradually expelled into the air cavity between the energy emitting source 5 and the liquid surface, which can significantly reduce the residual bubbles on the liquid surface, improve the overall transparency of the ice block, and reduce the phenomenon that the ice block is white in the latest freezing region as in the related art three.

[0125] In some embodiments, the energy emitting source 5 is located above the top wall of the containing cavity 21 and is spaced apart from the containing cavity 21.

[0126] In the present embodiment, the energy emitting source 5 is located outside the accommodation cavity 21 and above the top wall of the accommodation cavity 21. For example, the energy emitting source 5 can be mounted outside the top wall of the ice making container 2 so as to be spaced apart from the accommodation cavity 21 in the ice making container 2. Alternatively, the energy emitting source 5 can be spaced apart from the top wall of the ice making container 2.

[0127] The energy emitting source 5 can irradiate into the accommodation cavity 21 through the top wall of the accommodation cavity 21. By locating the energy emitting source 5 outside the accommodation cavity 21, the energy emitting source 5 can be prevented from contacting the liquid medium 6, thereby improving the safety and hygiene of the ice cubes produced. In addition, the energy emitting source 5 can be protected, thereby prolonging its service life. Furthermore, the ice cubes can be formed in the same shape as the accommodation cavity 21, thereby improving the aesthetic appearance. Moreover, the energy emitting source 5 can occupy less of the effective volume of the accommodation cavity 21, thereby improving the utilization rate of the effective volume of the accommodation cavity 21.

[0128] In some embodiments, the energy emitting source 5 is spaced apart from the ice formed by the liquid medium 6 when the liquid medium 6 in the accommodation cavity 21 is frozen.

[0129] In some embodiments, the energy emitting source 5 is spaced apart from the ice formed by the liquid medium 6 when the liquid medium 6 in the accommodation cavity 21 is frozen.

[0130] In some embodiments, as shown in FIGS. 8 and 10, at least part of the energy emitting source 5 is immersed in the liquid medium 6 when the liquid medium 6 is contained in the accommodation cavity 21.

[0131] In the present embodiment, at least part of the energy emitting source 5 is located below the liquid level of the liquid medium 6. Most or all of the light radiation emitted by the energy emitting source 5 can irradiate into the accommodation cavity 21, thereby increasing the amount of light radiation emitted by the energy emitting source 5 that irradiates into the accommodation cavity 21. As a result, the time during which the light radiation irradiates the changing ice-water interface is increased, and the area of the ice-water interface irradiated by the light radiation is increased.

[0132] The positions of the energy emitting source 5 and the cold source 4 can be set according to actual conditions. For example, the energy emitting source 5 and the cold source 4 can be oppositely arranged, or the energy emitting source 5 and the cold source 4 can be arranged at a certain angle apart from each other; or the cold source 4 is arranged at the center of the containing cavity 21, the ice making container 2 is transparent and is placed in the installation compartment of the energy emitting source 5, and the peripheral wall of the ice making container 2 can receive the radiation output by the energy emitting source 5.

[0133] In some embodiments, when the containing cavity 21 contains the liquid medium 6 to be made into ice, the distance h between the energy emitting source 5 and the liquid surface satisfies: 0mm≤h≤100mm.

[0134] In some embodiments, the ice making container 2 forms an exhaust cavity 23 and at least one containing cavity 21 for making ice, the exhaust cavity 23 is located above the containing cavity 21 and communicates with the containing cavity 21, and the energy emitting source 5 is located in the exhaust cavity 23.

[0135] In some embodiments, the ice making container 2 forms an exhaust cavity 23 and at least one containing cavity 21 for making ice, the exhaust cavity 23 is located above the containing cavity 21 and communicates with the containing cavity 21, and the energy emitting source 5 is located in the exhaust cavity 23.

[0136] The energy emitting source 5 is installed in the exhaust cavity 23, or the energy emitting source 5 is installed at one end of the exhaust cavity 23 away from the containing cavity 21, or the energy emitting source 5 is arranged apart from one end of the exhaust cavity 23 away from the containing cavity 21, and the energy emitting source 5 can output radiation into the containing cavity 21 through the exhaust cavity 23. In other words, the energy emitting source 5 is arranged above the containing cavity 21, the energy emitting source 5 is arranged apart from the liquid surface of the liquid medium 6, and the distance h between the energy emitting source 5 and the liquid surface satisfies: 0mm≤h≤100mm.

[0137] For example, the distance h between the energy emitting source 5 and the liquid surface can be 0, 10mm, 35mm, 50mm, 65mm, 80mm, 90mm or 100mm. When h=0, the energy emitting source 5 is flush with the liquid surface, and when h>0, the energy emitting source 5 is arranged apart from the liquid surface.

[0138] It can be understood that the energy emitting source 5 is not immersed in the liquid medium 6. When the liquid medium 6 is frozen, the volume of the ice is larger than that of the liquid medium 6, and the ice interface rises relative to the original liquid surface position. In the case that the energy emitting source 5 is flush with the liquid surface or the distance between the energy emitting source 5 and the liquid surface is less than the rising height of the ice interface, at least part of the energy emitting source 5 will be located in the ice after the liquid medium 6 is frozen; in the case that the distance between the energy emitting source 5 and the liquid surface is greater than the rising height of the ice interface, the energy emitting source 5 is arranged apart from the interface of the liquid medium 6 after being frozen.

[0139] In the embodiment, by setting the distance between the energy emitting source 5 and the liquid surface, the contact between the energy emitting source 5 and the liquid surface when the liquid medium 6 is not frozen can be reduced, the safety and hygiene of the obtained ice block can be improved, the energy emitting source 5 can be protected, and the service life of the energy emitting source 5 can be prolonged; meanwhile, by arranging the energy emitting source 5 in the exhaust cavity 23, the effective volume of the containing cavity 21 can be less occupied by the energy emitting source 5, and the utilization rate of the effective volume of the containing cavity 21 can be improved.

[0140] For example, the energy emitting source 5 can be arranged in the exhaust cavity 23, so that the bubbles can escape from the liquid medium 6 to the exhaust cavity 23 when the bubbles are gradually pushed to the unfrozen area close to the energy emitting source 5 by the ice layer; or the exhaust cavity 23 can be arranged at the top of the containing cavity 21, so that the bubbles can be more easily discharged to the exhaust cavity 23 due to the buoyancy; or the exhaust cavity 23 can be arranged at the middle or upper part of the containing cavity 21, so that the bubbles can escape to the exhaust cavity 23 due to the buoyancy.

[0141] According to the ice making device provided in the embodiment, by arranging the cold source 4, the energy emitting source 5 and the exhaust cavity 23, and by arranging the energy emitting source 5 in the exhaust cavity 23 and setting the distance h between the energy emitting source 5 and the liquid surface, on the one hand, the energy emitting source 5 can effectively reduce the surface tension of the ice-water interface by outputting radiation, and the bubbles adhering to the ice-water interface can be reduced; the cold source 4 can provide cold energy to the liquid medium 6 in the containing cavity 21 to make the liquid medium 6 freeze layer by layer, so that the bubbles are continuously pushed and pressed by the ice layer, and then gradually gather in the exhaust cavity 23 until the bubbles escape from the liquid medium 6 without being frozen in the middle of the ice, so that the overall transparency of the ice block is improved, the appearance of the ice block is improved, the melting time of the ice block is prolonged, the melting rate of the ice block is reduced, and the ice cooling effect is improved; on the other hand, the contact between the energy emitting source 5 and the liquid surface when the liquid medium 6 is not frozen can be reduced, and the safety and hygiene of the obtained ice block can be improved.

[0142] In some embodiments, the ice making process of the ice making device includes a crystallization stage, in which the temperature difference ΔT1 between the surface of the energy emitting source and the liquid surface satisfies 4℃≤ΔT1≤40℃, and the temperature difference ΔT2 between the liquid surface and the ice crystal zone satisfies 0℃≤ΔT2≤8℃.

[0143] For example, ΔT1 can be 4℃, 10℃, 13℃, 18℃, 20℃, 25℃, 32℃, 35℃ or 40℃, and ΔT2 can be 0℃, 3℃, 5℃, 6℃ or 8℃.

[0144] In the crystallization stage, the liquid medium 6 is gradually frozen from liquid to solid, and due to the presence of the energy emitting source 5, a plurality of temperature zones are formed in the containing cavity 21, the temperature is higher near the energy emitting source 5, the temperature difference ΔT1 between the surface of the energy emitting source 5 and the liquid surface is greater than the temperature difference ΔT2 between the liquid surface and the ice crystal zone, the radiation emitted by the energy emitting source 5 is radiated to the ice-water interface of the newly formed ice, and is also radiated to the ice-water interface of the solid ice surface in the ice crystal zone. Under the action of the radiation, the surface tension of the ice-water interface is reduced, and the bubbles adsorbed on the ice-water interface escape; at the same time, due to the output of heat by the energy emitting source 5 during operation, the temperature in the area near the energy emitting source 5 rises, the thickness of the ice crystal zone in the containing cavity 21 decreases, the total amount of solid ice in the ice crystal zone decreases, the probability of the bubbles being adsorbed by the solid ice during the process of floating up is reduced, and the bubbles have less resistance to escape, thereby the number of frozen bubbles can be reduced and the transparency of the ice block can be improved.

[0145] In some embodiments, the ice making process of the ice making device includes a crystallization stage, and in the crystallization stage, the temperature difference ΔT1 between the surface of the energy emitting source 5 and the liquid surface satisfies 10℃≤ΔT1≤25℃.

[0146] For example, ΔT1 can be 11℃, 12℃, 14℃, 16℃, 17℃, 19℃, 21℃, 23℃ or 24℃.

[0147] In some embodiments, as shown in FIG. 1 and FIG. 8, the ice making container 2 further forms an exhaust cavity 23 in communication with the containing cavity 21, and the exhaust cavity 23 is located above the containing cavity 21.

[0148] For example, one or more exhaust cavities 23 can be provided, each containing cavity 21 is in communication with the exhaust cavity 23, and the exhaust cavity 23 and the containing cavity 21 can be integrally connected, or can be connected by adhesive or thread, etc.

[0149] In this embodiment, during the freezing process of the liquid medium 6 in the containing cavity 21, the bubbles are gradually pushed out by the ice layer into the exhaust cavity 23, thereby the residual bubbles on the liquid surface can be significantly reduced, the number of residual bubbles in the liquid medium 6 can be significantly reduced, the overall transparency of the ice block can be improved, and the phenomenon that the ice block in the last freezing area appears white due to the bubbles failing to be discharged from the liquid medium in the related art three can be reduced.

[0150] For example, the exhaust cavity 23 can be arranged near the energy emitting source 5, so that when the bubbles are gradually pushed out by the ice layer to the un-frozen area near the energy emitting source 5, the bubbles can escape from the liquid medium 6 into the exhaust cavity 23; or the exhaust cavity 23 can be arranged at the top of the containing cavity 21, so that the bubbles are more easily discharged to the exhaust cavity 23 due to the buoyancy; or the exhaust cavity 23 can be arranged at the middle or upper part of the containing cavity 21, so that the bubbles are more easily discharged to the exhaust cavity 23 due to the buoyancy.

[0151] In some embodiments, as shown in FIG. 1, at least a part of the wall outside the ice making container 2 is provided with a thermal insulation layer 3.

[0152] In the present embodiment, all or part of the wall outside the ice making container 2 is provided with a thermal insulation layer 3, which is used to isolate the ice making container 2 from the temperature of the outside world, so that the wall of the ice making container 2 covered by the thermal insulation layer 3 reduces heat exchange with the outside world, thereby playing a thermal insulation effect on the containing cavity 21.

[0153] In the case where part of the wall outside the ice making container 2 is provided with a thermal insulation layer 3, the cold source 4 can supply cold to the containing cavity 21 through the wall of the ice making container 2 which is not provided with a thermal insulation layer 3.

[0154] The thermal insulation layer 3 can be a foamed material layer or a flexible thermal insulation layer 3, etc.

[0155] In the present embodiment, the refrigeration system can be connected to the wall of the ice making container 2 which is not provided with a thermal insulation layer 3, and the cold air of the refrigeration system is forced to flow to the wall which is not provided with a thermal insulation layer 3; or the ice making device is placed in the freezer compartment of the storage equipment, and the cold air in the freezer compartment provides cold to the containing cavity 21 through the wall which is not provided with a thermal insulation layer 3; or a semiconductor refrigeration sheet or other refrigeration device directly exchanges heat with the wall of the ice making container 2 which is not provided with a thermal insulation layer 3 to provide cold to the containing cavity 21.

[0156] In the case where all the wall outside the ice making container 2 is provided with a thermal insulation layer 3, the thermal insulation layer 3 covers the outer wall of the ice making container 2, and the refrigeration system can be connected to part of the wall of the ice making container 2 to supply cold in a directional manner; or a semiconductor refrigeration sheet or other refrigeration device directly exchanges heat with part of the wall of the ice making container 2 to supply cold to the containing cavity 21 in a directional manner.

[0157] In some embodiments, in the case where the ice making container 2 is provided with a thermal insulation layer 3, the working power of the energy emitting source 5 is P, which satisfies: 0.3W≤P≤3W.

[0158] In the present embodiment, the working power P of the energy emitting source 5 can be 0.3W, 1.5W, 2W, 2.5W or 3W, which can be determined according to the volume of the containing cavity 21, the shape of the containing cavity 21, the structure of the ice making container 2 and the type of the liquid medium 6 in actual use.

[0159] It can be understood that, due to the provision of the thermal insulation layer 3, the liquid medium 6 in the containing cavity 21 is frozen by a directional layer-by-layer freezing manner, the freezing rate is slow, the ice-water interface changes slowly, the energy radiation emitted by the energy emitting source 5 irradiates on the ice-water interface for a longer time, the low-intensity energy radiation generated by the low-power energy emitting source 5 can reduce the ice-water interface tension, save energy consumption, and improve the freezing rate.

[0160] In some embodiments, the working power of the energy emitting source 5 is P, which satisfies: 0.5W≤P≤10W, in the case that the ice making container 2 is not provided with the heat preservation layer 3.

[0161] In the embodiment, the working power P of the energy emitting source 5 can be 0.5W, 0.8W, 2W, 3W, 3.5W, 5W, 6.5W, 8W or 10W, which can be determined according to the volume of the containing cavity 21, the shape of the containing cavity 21, the structure of the ice making container 2 and the type of the liquid medium 6 in actual use.

[0162] In the embodiment, since the heat preservation layer 3 is not provided, the overall wall surface of the ice making container 2 can exchange heat with the cold source 4, and the cold source 4 can provide more cold energy for the containing cavity 21, so that the freezing rate of the liquid medium 6 is fast, the ice-water interface changes fast, the time for the energy radiation emitted by the energy emitting source 5 to irradiate the ice-water interface is shortened, and compared with the low-intensity energy radiation irradiation, the ice-water interface may not receive the energy radiation in the process of rapid change, resulting in that the surface tension of the ice-water interface is not effectively reduced, and the adsorption force of the ice-water interface to the bubbles cannot be well reduced. The high-intensity energy radiation generated by the high-power energy emitting source 5 is used to irradiate the rapidly changing ice-water interface, so as to quickly and effectively reduce the surface tension of the ice-water interface.

[0163] In some embodiments, the working power of the energy emitting source 5 is P, which satisfies: 3W≤P≤10W, in the case that the ice making container 2 is not provided with the heat preservation layer 3.

[0164] In the embodiment, the working power P of the energy emitting source 5 can be 3W, 4.5W, 5.5W, 6W, 9W or 10W, which can be determined according to the volume of the containing cavity 21, the shape of the containing cavity 21, the structure of the ice making container 2 and the type of the liquid medium 6 in actual use.

[0165] In some embodiments, in the case that the energy emitting source 5 is a light source, the wavelength of the energy radiation emitted by the energy emitting source 5 is λ, which satisfies: 100nm≤λ.

[0166] In the embodiment, the wavelength of the energy radiation emitted by the energy emitting source 5 can be 100nm, 200nm, 450nm, 700nm, 1000nm, 1200nm or higher wavelength light.

[0167] For example, the energy radiation output by the energy emitting source 5 can have a wavelength λ satisfying 400nm≤λ≤700nm, for example, λ can be 400nm, 500nm, 650nm or 700nm, i.e. the light is visible light; or the energy radiation output by the energy emitting source 5 can have a wavelength λ satisfying λ≥1000nm, for example, λ can be 1000nm, 1200nm, 1350nm or 1500nm, i.e. the light is infrared light with a wavelength of 1000nm or more. It has been proved by experiments that the energy radiation generated by the energy emitting source 5 can reduce the surface tension of the ice-water interface and improve the transparency of the ice block when the wavelength of the energy radiation is greater than 100nm.

[0168] In some embodiments, as shown in FIGS. 2, 3 and 4, the energy radiation output by the energy emitting source 5 has an irradiation angle β, and the shortest distance h between the energy emitting source 5 and the containing cavity 21 satisfies 20°≤β≤140° and h≤50mm.

[0169] The irradiation angle of the energy radiation output by the energy emitting source 5 should be such that the energy radiation can irradiate the changing ice-water interface as much as possible during the growth of the ice, so that the energy radiation generated by the energy emitting source 5 can always irradiate the ice-water interface through the unfrozen liquid medium 6 during the approach of the ice-water interface to the energy emitting source 5. The irradiation angle β of the energy radiation output by the energy emitting source 5 can be 20°, 30°, 50°, 60°, 100°, 130° or 140°. The greater the irradiation angle β of the energy radiation output by the energy emitting source 5, the longer the time during which the energy radiation output by the energy emitting source 5 can irradiate a larger area of the ice-water interface.

[0170] The energy emitting source 5 is arranged on the liquid surface, and the energy emitting source 5 is arranged at a distance from the liquid surface. The smaller the shortest distance h between the energy emitting source 5 and the containing cavity 21, the closer the energy emitting source 5 is to the interface of the liquid medium 6 in the containing cavity 21, and the greater the amount of energy radiation output by the energy emitting source 5 entering the containing cavity 21.

[0171] In the case where the shortest distance h between the energy emitting source 5 and the containing cavity 21 satisfies 0mm<h≤50mm, the shortest distance h between the energy emitting source 5 and the containing cavity 21 can be 10mm, 15mm, 25mm, 30mm, 45mm or 50mm, i.e. the energy emitting source 5 is arranged at a distance from the containing cavity 21 and the interface of the liquid medium 6, so as to avoid the contact between the energy emitting source 5 and the liquid medium 6, which can improve the safety and hygiene of the ice block prepared, and can also protect the energy emitting source 5 and prolong its service life.

[0172] In the case that the shortest distance h from the energy emitting source 5 to the containing cavity 21 satisfies h=0 mm, the energy emitting source 5 is arranged in the containing cavity 21, and the energy emitting source 5 can be arranged on the side wall of the ice making container 2, for example, the energy emitting source 5 can be arranged on the inner side wall or the outer side wall of the ice making container 2, so as to improve the radiation amount of the energy radiation output by the energy emitting source 5 into the containing cavity 21.

[0173] In the embodiment, in the case that the energy emitting source 5 is determined, the smaller the shortest distance h from the energy emitting source 5 to the containing cavity 21, the larger the energy radiation irradiation angle β of the energy radiation output by the energy emitting source 5, and the larger the time and area of the energy radiation output by the energy emitting source 5 irradiating on the ice-water interface.

[0174] For example, as shown in FIG. 2, FIG. 3 and FIG. 4, the circular shape represents the spherical containing cavity 21; the concentric semicircular energy radiation intensity output by the energy emitting source 5 arranged outwardly with the coordinate origin as the center; and the lines diverging outwardly with the coordinate origin as the center represent the angle, and the included angle between two adjacent lines is 10°.

[0175] As shown in FIG. 2, in the case that h=0 mm and β=140°, the energy radiation output by the energy emitting source 5 can completely enter the containing cavity 21, and the energy radiation can irradiate at different heights of the containing cavity 21; as shown in FIG. 3, in the case that h=10 mm and β=80°, the energy radiation received by the bottom of the containing cavity 21 is weak; as shown in FIG. 4, in the case that h=50 mm and β=60°, the radiation amount of the energy radiation output by the energy emitting source 5 into the containing cavity 21 is small, and the energy radiation cannot reach the bottom of the containing cavity 21, and the energy radiation received by the ice-water interface close to the bottom of the containing cavity 21 is weak.

[0176] In some embodiments, in the case that the energy emitting source 5 is a light source, it satisfies: 3720≤E=cL / (r cos 0.5β)≤360000. Wherein, E represents the illumination; c is a coefficient, c=1; r is the farthest distance from the energy emitting source 5 to the inner wall of the containing cavity 21, in meters; and L is the luminous intensity of the energy emitting source 5, in candela.

[0177] In the embodiment, E can be 5800, 10200, 23000, 93000 or 360000, by setting the illumination range of the energy emitting source 5, the range and quality of the energy radiation of the energy emitting source 5 can be improved, and the transparency of the ice block can be improved.

[0178] In some embodiments, in the case that the energy emitting source 5 is a light source, the luminous intensity of the energy emitting source 5 is L, and the farthest distance from the energy emitting source 5 to the inner wall of the containing cavity 21 is r, it satisfies: 1500 LUX≤cL / r 2 ≤360000 LUX.

[0179] wherein, L is the luminous intensity of the energy emitting source 5, in units of candela; r is the farthest distance from the energy emitting source 5 to the inner wall of the containing cavity 21, in units of meters; c is a coefficient, c = 1; E represents the illumination, E = cL / r 2 .

[0180] Exemplarily, in the case where the energy emitting source 5 is arranged apart from the containing cavity 21, the farthest distance from the energy emitting source 5 to the inner wall of the containing cavity 21 can be the sum of the distance between the energy emitting source 5 and the containing cavity 21 and the distance between the opposite side walls of the containing cavity 21 in the direction of the irradiation angle of the energy emitting source 5; in the case where the energy emitting source 5 is mounted on the wall surface of the containing cavity 21, the farthest distance from the energy emitting source 5 to the inner wall of the containing cavity 21 can be the distance between the opposite side walls of the containing cavity 21 in the direction of the irradiation angle of the energy emitting source 5.

[0181] wherein, cL / r 2 may be 1500 LUX, 4500 LUX, 15000 LUX, 85000 LUX, 100000 LUX, 250000 LUX, 300000 LUX or 350000 LUX.

[0182] Exemplarily, in the case where cL / r 2 is 360000 LUX, the farthest distance from the energy emitting source 5 to the inner wall of the containing cavity 21 is 10mm, and the energy emitting source 5 comprises 3 lamp beads, each of which is tested to be 12300 mcd at 150mA; in the case where cL / r 2 is 1500 LUX, the farthest distance from the energy emitting source 5 to the inner wall of the containing cavity 21 is 80mm, and the energy emitting source 5 comprises 1 lamp bead, which is tested to be 9300 mcd at 150mA.

[0183] According to the ice making device provided by the embodiments of the present application, on the one hand, the cold source 4 and the energy emitting source 5 are arranged to reduce the surface tension of the ice-water interface through the output energy radiation, reduce the bubbles attached to the ice-water interface, the cold source 4 can provide cold to the liquid medium 6 in the containing cavity 21 to make the liquid medium 6 freeze layer by layer, so that the bubbles are continuously squeezed by the ice layer, and then gradually gather to the last freezing part of the containing cavity 21 until escaping from the liquid medium 6 without being frozen in the middle of the ice, thereby improving the overall transparency of the ice block, improving the appearance of the ice block, prolonging the melting time of the ice block, reducing the melting rate of the ice block, and improving the ice cooling effect; on the other hand, the illumination is controlled to satisfy 1500 LUX ≤ cL / r 2≤360000LUX, the energy radiation outputted by the energy emitting source 5 can be controlled by controlling the luminous intensity of the energy emitting source 5 and the farthest distance from the energy emitting source 5 to the inner wall of the containing cavity 21, so as to meet the conditions of making transparent ice for containing cavities 21 with different volumes and shapes, and improve the application scenarios.

[0184] In some embodiments, the volume of the containing cavity 21 is V, and the working power of the energy emitting source 5 is P, which satisfies: 0.2W≤P≤50W, 20ml≤V≤200ml.

[0185] In some embodiments, the working power P of the energy emitting source 5 can be 0.2W, 4W, 15W, 28W, 40W or 50W, which can be determined according to the volume of the containing cavity 21, the shape of the containing cavity 21, the structure of the ice making container 2 and the type of the liquid medium 6 in actual use; the volume V of the containing cavity 21 can be 20ml, 60ml, 100ml, 140ml, 160ml or 200ml, which can be determined according to the application scenario in actual use.

[0186] It can be understood that, in order to meet the radiation intensity of the energy radiation outputted by the energy emitting source 5 to the ice-water interface in the containing cavity 21, the energy radiation outputted by the energy emitting source 5 can provide sufficient radiation intensity to the ice-water interface far away from the energy emitting source 5, so as to reduce the situation that the ice-water interface far away cannot receive sufficient radiation intensity due to the gradual attenuation of the energy radiation with the increase of the distance, and the bubbles at this place are frozen into the ice block to reduce the transparency of the ice block. The greater the volume of the containing cavity 21, the greater the working power of the energy emitting source 5 required, and the smaller the volume of the containing cavity 21, the smaller the working power of the energy emitting source 5 required.

[0187] For example, when the volume V of the containing cavity 21 is 20ml, the working power P of the energy emitting source 5 can be 0.2W; when the volume V of the containing cavity 21 is 100ml, the working power P of the energy emitting source 5 can be 28W.

[0188] In some embodiments, at least part of the inner wall of the containing cavity 21 is provided with a heat absorption layer.

[0189] The heat absorption layer can be the wall body of the containing cavity 21, or a film layer attached to the wall of the containing cavity 21. The heat absorption layer is used to absorb the energy radiation outputted by the energy emitting source 5. The inner wall of the containing cavity 21 is provided with a heat absorption layer region. Under the irradiation of the energy emitting source 5, the temperature of the wall surface of the region is increased, which reduces the surface tension of the wall surface of the region, thereby reducing the adsorption force of the region to the bubbles, and further making the bubbles attached to the inner wall of the containing cavity 21 more easily be discharged, reducing the number of bubbles on the surface layer of the ice block, and improving the transparency of the ice block.

[0190] According to the ice making device provided in the embodiment, the cold source 4 and the energy emitting source 5 are arranged, and the heat absorbing layer is arranged on at least part of the inner wall of the containing cavity 21. The energy emitting source 5 can reduce the surface tension of the ice-water interface through the output energy radiation, and reduce the bubbles adhered to the ice-water interface. The heat absorbing layer heats the inner wall of the containing cavity 21 in the area where the heat absorbing layer is arranged under the irradiation of the energy radiation, so as to reduce the surface tension of the wall surface in the area, and thus reduce the adsorption force of the bubbles in the area. Therefore, the bubbles adhered to the inner wall of the containing cavity 21 are more easily discharged, the number of bubbles in the surface layer of the ice block is reduced, and the transparency of the surface layer of the ice block is improved. The cold source 4 can provide cold energy for the liquid medium 6 in the containing cavity 21, so as to make the liquid medium 6 freeze layer by layer. The bubbles are continuously extruded and pressed by the ice layer, and then gradually gather to the last freezing position of the containing cavity 21 until the bubbles escape from the liquid medium 6 without being frozen in the middle of the ice. The overall transparency of the ice block is improved, the appearance of the ice block is improved, the melting time of the ice block is prolonged, the melting rate of the ice block is reduced, and the ice cooling effect is improved.

[0191] In some embodiments, the ice making container 2 is made of silica gel, and at least part of the inner wall of the ice making container 2 is dark.

[0192] In some embodiments, the ice making container 2 is made of silica gel, and at least part of the inner wall of the ice making container 2 is dark.

[0193] In the embodiment, the ice making container 2 is made of silica gel, which has the advantages of safety, easy cleaning and convenient ice block demolding. At least part of the inner wall of the ice making container 2 is dark to form a heat absorbing layer. The inner wall of the ice making container 2 is heated under the irradiation of the energy radiation to reduce the surface tension of the wall surface in the area, so as to reduce the adsorption force of the bubbles in the area. Therefore, the bubbles adhered to the inner wall of the containing cavity 21 are more easily discharged, the number of bubbles in the surface layer of the ice block is reduced, and the transparency of the surface layer of the ice block is improved.

[0194] In some embodiments, the ice making container 2 is made of silica gel, and at least part of the inner wall of the ice making container 2 is dark.

[0195] In some embodiments, the ice making container 2 is made of silica gel, and at least part of the inner wall of the ice making container 2 is dark.

[0196] In the embodiment, the inner wall of the ice making container 2 is black to form a heat absorption layer. The black color has the strongest light absorption capacity and good light absorption performance. The inner wall of the ice making container 2 is heated under the irradiation of energy radiation to reduce the surface tension of the wall surface of the region, so that the adsorption of the region to the bubbles is reduced, and the bubbles attached to the inner wall of the accommodation cavity 21 are more easily discharged, the number of bubbles on the surface layer of the ice block is reduced, and the transparency of the surface layer of the ice block is improved.

[0197] The heat absorption layer has at least the following two forms.

[0198] In one form, the ice making container 2 is made of black silicone to form the heat absorption layer.

[0199] In the embodiment, the ice making container 2 is made of black silicone, which can achieve the heat absorption effect and is safe and easy to clean.

[0200] In another form, the inner wall of the ice making container 2 is coated with a black coating to form the heat absorption layer.

[0201] In the embodiment, the heat absorption layer is formed by coating the black coating. The area and shape of the heat absorption layer are easy to control, and the heat absorption layer is suitable for application in a complex structure of the ice making container 2.

[0202] As shown in FIGS. 1 and 8-10, in some embodiments, the ice making device also includes a heater 7, which is installed on the ice making container 2.

[0203] The heater 7 can be installed on at least one of the inner wall, the outer wall, and the inner wall and the outer wall of the ice making container 2. For example, the heater 7 can be at least one of a heating film, a heating wire, and a heating plate.

[0204] In the embodiment, the heater 7 can generate heat radiation to the accommodation cavity 21. The temperature of the liquid medium 6 is increased to reduce the surface tension of the ice-water interface. The heat radiation and the energy radiation cooperate to effectively reduce the adsorption of the ice-water interface to the bubbles, thereby further reducing the bubbles attached to the ice-water interface.

[0205] In some embodiments, as shown in FIG. 9, the heater 7 is installed on the wall surface of the ice making container 2 away from the cold source 4.

[0206] In the embodiment, the liquid medium 6 in the accommodation cavity 21 is frozen layer by layer along the direction from the cold source 4 to the direction away from the cold source 4, the heater 7 is installed on the wall of the ice making container 2 away from the cold source 4, the bubble is arranged on the opposite side of the heater 7 and the cold source 4, the bubble is gradually pushed to the area away from the cold source 4 by the ice layer, the heater 7 is arranged in the area away from the cold source 4, the heater 7 can radiate heat to the accommodation cavity 21, the heat output to the ice-water interface can reduce the surface tension of the ice-water interface, thereby effectively reducing the adsorption of the ice-water interface to the bubble, thereby improving the transparency of the ice block.

[0207] In some embodiments, as shown in FIG. 9 and FIG. 10, the heater 7 is installed on the outer wall of the ice making container 2.

[0208] In the embodiment, the heat radiation output by the heater 7 can pass through the outer wall of the accommodation cavity 21 to output heat to the accommodation cavity 21, arranging the heater 7 outside the accommodation cavity 21 can avoid the contact between the heater 7 and the liquid medium 6, can improve the safety and hygiene of the ice block, can also protect the heater 7 and prolong the service life of the heater 7, at the same time, the ice block is formed in the same shape as the accommodation cavity 21, the appearance is improved, at the same time, the heater 7 can reduce the occupation of the effective volume of the accommodation cavity 21, and the utilization rate of the effective volume of the accommodation cavity 21 is improved.

[0209] The structure of the heater 7 at least includes the following three kinds:

[0210] First, the heater 7 is a film type and is attached to the outer wall of the ice making container 2.

[0211] In the embodiment, the film type heating element can be attached to the outer wall of the ice making container 2, the heating area is large, the temperature in the heating area is relatively uniform, the heat radiation can be uniformly output to the accommodation cavity 21, the heat radiation generated by the heater 7 can be uniformly output to the ice-water interface, the ice-water interface is subjected to a relatively uniform radiation intensity, the surface tension difference of the ice-water interface is small, and the transparency of the ice block is good.

[0212] Second, the heater 7 is a linear type and is installed on the outer wall of the ice making container 2.

[0213] The linear heating element can be pasted or wound in a net shape on the outer wall of the ice making container 2, which can not only have a heating effect, but also can reduce the heating area and save costs.

[0214] The linear heating element can be a continuous type in a snake shape or a launch shape.

[0215] Third, the heater 7 is a plate type and is installed on the outer wall of the ice making container 2, at least part of the area of the plate type heating element is in contact with the outer wall of the ice making container 2 to transmit heat to the accommodation cavity 21 through the outer wall of the ice making container 2.

[0216] In some embodiments, the ratio of the area of the heater 7 to the area of the inner wall surface of the containing cavity 21 is b, which satisfies: 0.02≤b≤0.5.

[0217] In some embodiments, the area of the heater 7 is less than the area of the inner wall surface of the containing cavity 21, and the ratio of the area of the heater 7 to the area of the inner wall surface of the containing cavity 21 is b, which can be 0.02, 0.1, 0.2, 0.4, or 0.5.

[0218] In the present embodiment, the area of the heater 7 is the heating area of the heater 7. In the case where the heater 7 is a linear heating wire, the ratio of the area of the heater 7 to the area of the inner wall surface of the containing cavity 21 can be as small as 0.02. In the case where the heater 7 is a film-type heating film, the ratio of the area of the heater 7 to the area of the inner wall surface of the containing cavity 21 can be as large as 0.4. By setting the ratio of the heating area of the heater 7 to the area of the inner wall surface of the containing cavity 21 to be no more than 0.5, the reduction of the ice-water interfacial tension by the heat radiation output by the heater 7 can be achieved, and the influence of the heater 7 on the ice formation rate can be reduced.

[0219] In some embodiments, the heat transmission direction of the cold source 4 is opposite to the irradiation direction of the energy radiation output by the energy emitting source 5, and the distance from the heater 7 to the center of the energy emitting source 5 is less than the distance from the heater 7 to the center of the cold source 4.

[0220] In some embodiments, the heater 7 is arranged close to the energy emitting source 5. The energy emitting source 5 generates a small amount of heat radiation in addition to the energy radiation. The heat radiation generated by the energy emitting source 5 and the heat radiation generated by the heater 7 can further heat the liquid medium 6 in the vicinity, and the surface tension of the ice-water interface can be reduced by the temperature rise, thereby reducing the adsorption force of the ice-water interface on the bubbles.

[0221] In some embodiments, the heat transmission region of the cold source 4 is substantially fan-shaped, and the heat transmission direction of the cold source 4 is the central axis direction of the fan shape. The irradiation region of the energy radiation output by the energy emitting source 5 is also substantially fan-shaped, and the irradiation direction of the energy radiation output by the energy emitting source 5 is the central axis direction of the fan shape.

[0222] In the present embodiment, the cold source 4 and the energy emitting source 5 are arranged opposite to each other on the two sides of the ice making container 2.

[0223] For example, in the case where the containing cavity 21 is spherical, the cold source 4 and the energy emitting source 5 are arranged opposite to each other on the two sides of the containing cavity 21 along the radial direction of the ice making container 2. In the case where the containing cavity 21 is axisymmetric, the cold source 4 and the energy emitting source 5 are arranged opposite to each other on the two sides of the containing cavity 21 along the symmetry axis of the ice making container 2.

[0224] As shown in FIG. 1, the energy emitting source 5 and the cold source 4 can be arranged on the upper and lower sides of the accommodating cavity 21 in the vertical direction; or the energy emitting source 5 and the cold source 4 can be arranged on the left and right sides of the accommodating cavity 21 in the horizontal direction; or the energy emitting source 5 and the cold source 4 can be arranged on the oblique sides of the accommodating cavity 21 in the oblique direction.

[0225] In the embodiment, by oppositely arranging the heat transfer direction of the cold source 4 and the energy radiation irradiation direction of the energy emitting source 5, oppositely arranging the ice growth direction in the accommodating cavity 21 and the energy radiation irradiation direction, and oppositely arranging the energy radiation irradiation area and the heat transfer area of the cold source 4, the area of the energy radiation irradiation on the ice-water interface can be increased, and the energy radiation generated by the energy emitting source 5 can be uniformly irradiated on the ice-water interface, the ice-water interface can be subjected to more uniform radiation intensity, the surface tension difference of the ice-water interface is smaller, and the transparency of the ice block is better.

[0226] It can be understood that if the energy emitting source 5 is not oppositely arranged with the cold source 4, the irradiation area generated by the energy emitting source 5 is inclined relative to the heat transfer direction of the cold source 4, and the ice-water interface can be only partially irradiated by the energy emitting source 5. If the energy radiation output by the energy emitting source 5 cannot be uniformly irradiated on the ice-water interface, the area of the ice-water interface subjected to stronger energy radiation has smaller tension and weaker adsorption, the number of adsorbed bubbles is small, the transparency of the ice block is higher, but the ice growth rate is slow; the area of the ice-water interface subjected to weaker energy radiation has larger tension and stronger adsorption, the number of adsorbed bubbles is large, the transparency of the ice block is lower, but the ice growth rate is fast, and with the continuation of the ice formation process, the ice block can have a situation that one side has more bubbles and lower transparency, and the other side has fewer bubbles and higher transparency. Therefore, oppositely arranging the heat transfer direction of the cold source 4 and the energy radiation irradiation direction of the energy emitting source 5 can make the energy radiation generated by the energy emitting source 5 be uniformly irradiated on the ice-water interface, the energy radiation intensity difference of the ice-water interface is smaller, and each area of the ice-water interface can effectively reduce the adsorption of bubbles and improve the transparency of the ice block.

[0227] In some embodiments, the energy emitting source 5 is configured to output energy radiation to the accommodating cavity 21 from a first side of the ice making container 2, the cold source 4 is configured to supply cold to the accommodating cavity 21 from a second side of the ice making container 2, the first side is oppositely arranged with the second side, and the heater 7 is installed on the first side.

[0228] In the embodiment, the heater 7 and the energy emitting source 5 are installed on the same side of the ice making container 2, the heat radiation generated by the energy emitting source 5 and the heat radiation generated by the heater 7 can be superimposed and output to the cold source 4, the heat radiation generated by the energy emitting source 5 and the heat radiation generated by the heater 7 can be more uniformly output to the ice-water interface, the energy radiation intensity difference of the ice-water interface is smaller, and each area of the ice-water interface can effectively reduce the adsorption of bubbles and improve the transparency of the ice block.

[0229] In some embodiments, the vector angle between the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 is 180±10°, and the energy emitting source 5 is provided on both sides of the energy radiation.

[0230] In some embodiments, the vector angle between the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 is 180±10°, and the energy emitting source 5 is provided on both sides of the energy radiation.

[0231] In some embodiments, the vector angle between the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 is 180±10°, and the energy emitting source 5 is provided on both sides of the energy radiation.

[0232] In some embodiments, the vector angle between the heat transfer direction of the cold source 4 and the irradiation direction of the energy radiation output by the energy emitting source 5 is 180±10°, and the energy emitting source 5 is provided on both sides of the energy radiation.

[0233] In some embodiments, the energy emitting source 5 is used to output energy radiation from the first side of the ice making container 2 to the containing cavity 21, the wall of the ice making container 2 has at least one cooling section 22, the cold source 4 is used to supply cold to the outer wall of the cooling section 22, the cooling section 22 is provided opposite to the first side, and the heater 7 is installed on the first side.

[0234] The liquid medium 6 in the containing cavity 21 exchanges heat with the cold source 4 through the cooling section 22. In the case where the refrigeration system is directly connected to the ice making container 2, the cooling section 22 faces the cold air outlet of the refrigeration system, and the refrigeration system directly provides cold energy to the cooling section 22. In the case where the ice making device is placed in the refrigeration compartment of the storage equipment, the cold energy in the refrigeration compartment contacts the cooling section 22 to provide cold energy to the containing cavity 21. In the case where the cold source 4 is a semiconductor refrigeration sheet or other refrigeration device, the semiconductor refrigeration sheet or other refrigeration device can be attached to the cooling section 22 to directly provide cold energy to the containing cavity 21.

[0235] The heater 7 and the energy emitting source 5 are installed on the same side of the ice making container 2. The thermal radiation generated by the energy emitting source 5 and the thermal radiation generated by the heater 7 are superimposed to generate radiation that can be uniformly output to the cold source 4. The thermal radiation generated by the energy emitting source 5 and the thermal radiation generated by the heater 7 can be more uniformly output to the ice-water interface. The energy radiation intensity difference of the ice-water interface is small, and the ice-water interface can effectively reduce the adsorption force of bubbles in each region, thereby improving the transparency of the ice block.

[0236] In some embodiments, the energy emitting source 5 is installed above the containing cavity 21, the heater 7 is installed on the upper wall of the ice making container 2, and the cold source 4 is used to supply cold to the lower wall of the containing cavity 21.

[0237] The energy emitting source 5 and the heater 7 are both installed above the containing cavity 21, and the energy emitting source 5 and the heater 7 belong to heat sources, that is, the hot side is arranged on the upper side and the cold side is arranged on the lower side.

[0238] In this embodiment, the energy emitting source 5 can be spaced apart and arranged above the containing cavity 21, or the energy emitting source 5 can be installed in the containing cavity 21. The energy radiation output by the energy emitting source 5 is irradiated from above the containing cavity 21 to the lower wall of the containing cavity 21. The heat transfer direction of the cold source 4 is from the lower wall of the containing cavity 21 to the upper side of the containing cavity 21, that is, the energy emitting source 5 is arranged on the upper side and the cold source 4 is arranged on the lower side.
