Description

Technical Field

[0001] The utility model belongs to the technical field of ice making machines, and in particular relates to a water injection structure. Background Art

[0002] Ice makers are divided into freezers for household refrigerators and commercial ice makers. The freezing temperature for household refrigerators is generally around -18°C, while the freezing temperature for commercial ice makers can reach -46.5°C. Ice cubes made at low temperatures will be lower in temperature, more stable in structure and less likely to melt. Commercial ice makers mostly use flowing water to make ice. During the ice-making process, the orientation of the water injection port of the ice-making mold has a significant impact on the shaping, quality and efficiency of the ice cubes. When the water injection port is set below the mold, since bubbles and accumulated wind usually float upward, the water injection port located below will make it easier to discharge bubbles and accumulated wind from the mold to ensure the quality of the ice cubes. At the same time, the water injection port is kept away from the position where the ice cubes may be subjected to force in the future (that is, the top of the ice cubes) to avoid the formation of stress concentration areas in the ice cubes, which can effectively reduce the cracking or breakage of ice cubes due to stress during use.

[0003] Common ice-making molds are made by splicing the upper and lower parts. Then, when the water injection port is located in the lower mold, the lower mold can be set to a flip mode, and the lower mold can be rotated to splice with the upper mold to form an ice-making cavity, and then water is injected into the cavity through the lower mold to make ice. Therefore, it is urgent to design a water injection structure for rotating the lower mold. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figures 1 to 6 A water injection structure for rotating a lower mold shown in the figure comprises a main bin 1, a base 2 is installed on the upper part of the main bin 1, an evaporation plate 3 is provided on the right side of the bottom of the base 2, an upper mold 4 is provided on the bottom of the evaporation plate 3, a hinge seat 5 is symmetrically provided on the left side of the bottom of the base 2, a water receiving bin 6 is hinged between the hinge seats 5, a plurality of rows of mounting seats 7 are provided on the top of the water receiving bin 6, a lower mold 8 is installed between the mounting seats 7; a cold water tank 9 is provided at the bottom of the water receiving bin 6, a water storage frame 10 is extended downwardly from the rear side of the bottom of the cold water tank 9, and a water pump 11 is installed at the front side of the bottom of the cold water tank 9; the input end of the water pump 11 is connected to the water storage frame 10, and the output end of the water pump 11 is connected to the water receiving bin 6 upwardly by installing a water pipe 12; the bottom of the water receiving bin 6 is divided into a water sprinkling bin 13 and a water injection bin 14, which are separately arranged on the left and the right; A plurality of rows of water injection grooves 15 are provided at the bottom of the water injection bin 14, a sealing plate 16 is provided at the bottom of the water injection grooves 15, and a water filling hole 17 is connected between the left side of the water injection bin 14 and the right side of the water sprinkling bin 13; the bottom of the lower mold 8 is installed on the mounting base 7 by providing a mounting groove 18, and a water injection port 19 is provided in the middle of the mounting base 7; a plurality of water leakage holes 20 are provided on the right side of the water receiving bin 6; drainage holes 21 are provided downwardly on both the front and rear sides of the mounting base 7, a drainage groove 22 is clamped on the outer side of the water injection groove 15, and a plurality of groups of water diverting plates 23 are provided on the left and right sides of the drainage groove 22; a water guide plate 24 is provided on the water injection bin 14 below the water filling hole 17, and a plurality of water guide grooves 25 are provided on the water guide plate 24; an auxiliary rotating component 26 is provided on the right side of the top of the base 2, and the auxiliary rotating component 26 is hinged to the right part of the water receiving bin 6.

[0026] After the initial action of water falling naturally, the utility model injects water from the bottom of the lower mold 8 to complete the action of flowing water making ice. In the process of ice making, the bubbles can be completely discharged from the mold, making the ice cubes more crystal clear. Moreover, due to the continuous flushing and circulation of the water flow, the formed ice cubes have a larger density, a tighter and more stable structure, and the melting time of the ice balls is prolonged to ensure the quality of the ice cubes. Among them, by arranging a water leakage hole 20 on the right side of the water receiving bin 6, the water is introduced to the bottom of the lower mold 8 without affecting the mold, and then the water below is pumped into the lower mold 8 through the water injection port 19 by the water pump 11, so that the evaporation plate 3 located on the top of the upper mold 4 cools the water flowing through, so that the water slowly forms ice balls in the mold to complete the ice making.

[0027] Example 2

[0028] like Figures 1 to 6 The water injection structure for rotating the lower mold shown in the figure includes a main compartment 1, which is the shell of the ice maker and can be used to carry all components and isolate the ice making environment to prevent dust mixed in the outside air from entering and affecting the quality of the ice cubes. A base 2 is installed on the upper part of the main compartment 1, and the base 2 is across the inner top of the main compartment 1. An evaporation plate 3 is provided on the right side of the bottom of the base 2. The evaporation plate 3 can be fixedly installed on the bottom of the base 2 by a screw rod, and is used to stably install the lower upper mold 4. Then, when the refrigerant is compressed in the compressor, the temperature will rise. The high-temperature refrigerant will be cooled by the condenser and condensed into a liquid state. The liquid refrigerant will enter the evaporation plate 3 upward. In the evaporation plate 3, the liquid refrigerant will begin to evaporate due to the low temperature environment of the evaporation plate 3, and absorb the surrounding heat at the same time, so that the surrounding temperature is reduced. When water continues to flow into the upper mold 4, it can be cooled to below the freezing point through the evaporation plate 3 and begin to condense into an ice layer, achieving the effect of ice making.

[0029] It should be noted that the utility model uses flowing water to make ice, which can avoid the chaotic ice crystal structure formed when static water is used to make ice, resulting in the ice ball presenting an opaque and white appearance. The flowing water continuously impacts the evaporation plate 3, driving the ice cubes made to contain almost no bubbles, making the ice cubes appear crystal clear; at the same time, by replacing the static water to make ice, the ice cubes made are denser and more compact in structure, that is, by reducing the pores and cracks in the ice cubes, the transparency and hardness of the ice cubes are improved. In addition, the low-temperature ice making of the commercial ice maker (about -46.5°C) makes the ice cubes made by the utility model lower in temperature, more stable in structure and less likely to melt. Since this product is mainly used for making ice balls, the upper and lower molds 8 are both set to be semi-spherical, and then the two can be spliced ​​to form a spherical cavity for making ice balls.

[0030] A hinge seat 5 is symmetrically provided on the left side of the bottom of the base 2, and a water receiving bin 6 is hinged between the hinge seats 5. The left side of the top of the water receiving bin 6 is a rotating fulcrum. Then, when the lower mold 8 is installed on the top of the water receiving bin 6, the water receiving bin 6 can be pushed to rotate counterclockwise between the hinge seats 5 until the water receiving bin 6 is parallel to the base 2. At this time, the lower mold 8 on the top of the water receiving bin 6 will be spliced ​​with the upper mold 4 to form a plurality of spherical cavities for making ice balls.

[0031] For ease of understanding, the present embodiment specifically sets the number of molds to facilitate smooth understanding of the water injection scheme. The upper mold 4 and the lower mold 8 are each provided with 7 rows and 4 columns, for a total of 28 semicircular cavities. After the upper mold 4 and the lower mold 8 are spliced ​​together, 28 complete spherical cavities can be formed for the production of ice balls. The lower mold 8 is not directly installed on the water receiving bin 6. In order to achieve the effect of injecting water from the bottom when making ice, installation grooves 18 are provided at the bottom of the 28 semicircular cavities of the lower mold 8. The installation grooves 18 are square in shape. Correspondingly, a "7-row and 4-column" installation base 7 is provided on the top of the water receiving bin 6. The top view of the installation base 7 is square, which is used to adapt to the installation grooves 18 for the installation of the lower mold 8. After the lower mold 8 is installed on the top of the water receiving bin 6, it will be affected by the installation base 7 to form a closed space. Therefore, a water injection port 19 is provided in the middle of the installation base 7. The water injection port 19 runs through the installation base 7 and the water receiving bin 6. When water is stored under the water receiving bin 6, the water can be driven to pour upward into the assembled mold through the water injection port 19, and then cooled and made ice through the evaporation plate 3.

[0032] Example 3

[0033] In order to realize the water supply of the docking water tank 6, a cold water tank 9 is also installed at the bottom of the water receiving tank 6 for storing water to be poured. The installation position of the cold water tank 9 is on the right, so the left side of the water receiving tank 6 will be empty, and then the bottom of the water receiving tank 6 is divided into two parts. The empty part on the left is the water sprinkling tank 13, and the part overlapping with the cold water tank 9 is the water filling tank 14, that is, the water filling tank 14 will store the water for pouring, and then pump water upward to make it enter the mold to cooperate with ice making.

[0034] Since the upper and lower molds 8 need to be perfectly closed, the water filling bin 14 will be completely blocked, and when the water is automatically poured downward, it can fall into the top left side of the water receiving bin 6, and then flow to the multiple water leakage holes 20 opened on the right side of the water receiving bin 6, and the water can flow into the cold water tank 9 through the water leakage holes 20 for storage. It is known that a certain amount of water storage is required to pump water upward, so a smaller water storage frame 10 is also set in the cold water tank 9 to quickly accumulate water and improve ice making efficiency; the water storage frame 10 is located at the right rear side of the bottom of the cold water tank 9, and is extended downward, so that the water falling into the cold water tank 9 can flow to the water storage frame 10 with a lower horizontal terrain, completing rapid water accumulation.

[0035] A water pump 11 is installed on the front side of the bottom of the cold water tank 9, and the input end of the water pump 11 is connected to the water storage frame 10. After the water storage frame 10 is filled with water, the water pump 11 can be operated to pump out the water in the water storage frame 10. At the same time, the output end of the water pump 11 is connected upward to the water receiving bin 6 through the installation of a water pipe 12, that is, connected to the water sprinkling bin 13 on the left side. Then, the water pump 11 can be operated to pump the water in the water storage frame 10 upward into the water sprinkling bin 13 on the left side of the water receiving bin 6. It should be noted that there is a gap between the water sprinkling bin 13 and the water filling bin 14, so that the water filling bin 14 can exist alone and completely cover the cold water tank 9 downward, that is, the water entering the water sprinkling bin 13 cannot enter the water filling bin 14 again. Therefore, there are 7 water filling holes 17 connected between the left side of the water filling bin 14 and the right side of the water sprinkling bin 13, and then the water in the water sprinkling bin 13 can enter the water filling bin 14 to the right through the water filling holes 17. Correspondingly, in order to achieve accurate filling of water, a water filling hole 17 is also provided in the water filling bin 14. There are 7 rows of water injection grooves 15 at the bottom, and the water injection grooves 15 will be directly aligned with the 7 water filling holes 17 on the left side, and then the water pump 11 will operate to pump out water, and then it can enter the water sprinkling bin 13 upwards, and then enter the water injection groove 15 to the right through the water filling hole 17, and the water injection groove 15 will be aligned with each row of water injection ports 19 upwards, that is, the water entering the water injection groove 15 will continuously pour upwards into the water injection port 19 when the water volume is sufficient, and then enter the cavity in the upper and lower molds 8 after splicing through the mounting base 7 to complete the water injection. A sealing plate 16 is provided at the bottom of the water injection groove 15, so that the actual water collection amount of the water injection groove 15 can be reduced, and water can be quickly injected upwards in the environment formed by the sealing plate 16 and the water injection groove 15, and the water will continuously react with the evaporation plate 3 in the continuous flow, and slowly form ice balls in the mold.

[0036] Example 4

[0037] According to the third embodiment, when water is poured from top to bottom, it will first fall into the top left side of the water receiving bin 6, then flow to the multiple water leakage holes 20 opened on the right side of the water receiving bin 6, and then flow into the cold water tank 9 through the water leakage holes 20. When a certain amount of water is accumulated in the water storage frame 10 inwardly of the cold water, the water pump 11 is driven to pump out the water in the water storage frame 10, and then pump it upward into the water sprinkling bin 13 on the left side of the water receiving bin 6 through the water pipe 12. Then the water enters the 7 rows of water injection grooves 15 at the bottom of the water injection bin 14 through the 7 water filling holes 17. As the amount of water in the water injection grooves 15 increases, the water will gradually pour upward into the water injection port 19, and enter the mold cavity through the mounting base 7 to complete the water injection. It is known that the present embodiment uses the flowing water ice making method, so the water will always be in a flowing state, and the mold cavity will be continuously injected with water during the flow period, and the evaporation plate 3 will cool the water flowing through, so that the water slowly forms ice balls in the mold. The unfrozen water needs to be processed and discharged. Since a sealing plate 16 is provided at the bottom of the water injection groove 15, the water entering the mold cannot be effectively discharged. In addition, drainage holes 21 are provided downwardly on both the front and rear sides of the mounting base 7. Here, the shape of the mounting base 7 needs to be described in detail. Although the top view of the mounting base 7 is square, its front and rear sides conform to the shape of the lower mold 8 and have an upward bending trend. When the drainage holes 21 are provided on both the front and rear sides of the mounting base 7, it means that the horizontal position of the drainage holes 21 will be higher than the water injection holes, thereby ensuring that the water poured into the mold through the water injection holes will not be immediately discharged through the drainage holes 21. It is necessary to wait for the water to contact the top of the upper mold 4 or the ice layer upward through the water injection holes. After the ice layer is stacked, the remaining water will slide down and then be discharged downward into the cold water tank 9 through the drainage holes 21, so as to discharge the excess water and meet the basic standards of the flowing water ice making method.

[0038] A drainage trough 22 is mounted on the outside of the water filling trough 15 through a protruding clamping block, and a multi-component water plate 23 is provided on both sides of the drainage trough 22. The water plates are aligned with the drainage holes 21, that is, the water plates can further guide the water discharged downward through the drainage holes 21 to prevent it from hanging on the wall of the water filling bin 14, causing the evaporation plate 3 to continue to react downward to the water hanging on the wall after completing ice making, thereby prolonging the ice making time. Later, it will also be difficult to demould due to the problem of ice formation, affecting the efficiency of ice making.

[0039] At the same time, a water guide plate 24 is provided on the water filling bin 14 below the water filling hole 17, and a plurality of water guide grooves 25 are opened on the water guide plate 24. It is known that water will flow downward into the cold water tank 9 through the water leakage hole 20 on the right side of the water receiving bin 6, and the water pump 11 at the bottom of the cold water tank 9 will operate to pump water out, so that it will pour upward into the water sprinkling bin 13, and then enter the water filling groove 15 of the water filling bin 14 to the right through the water filling hole 17. The water filling groove 15 is located at a higher water level, which can adapt to the directional force of the water pump 11 based on the water flow, and the remaining flowing water will continue to stay in In order to further realize the utilization rate of water flow, a water guide plate 24 is specially arranged below the water filling hole 17 in the water sprinkling bin 13. The water level of the water guide plate 24 is relatively low, so the remaining water in the water sprinkling bin 13 can be discharged into the cold water tank 9 again through the water guide groove 25, and then flow downward again through the water guide plate 24 on the right side of the cold water tank 9. The discharged water can be processed again to "pour downward and fall into the top left side of the water receiving bin 6", thereby realizing the water circulation action, reducing water resource consumption and improving ice making efficiency.

[0040] Example 5

[0041] like Figures 1 to 6 The water injection structure for rotating the lower mold shown in the figure has an articulated seat 5 symmetrically arranged on the left side of the bottom of the base 2, and a water receiving bin 6 is hinged between the articulated seats 5, so that the water receiving bin 6 can rotate on the articulated seat 5, driving the lower mold 8 thereon to rotate counterclockwise, until the lower mold 8 is spliced ​​with the fixed upper mold 4 to form a plurality of spherical cavities for making ice balls. However, there are many parts on the water receiving bin 6, and a cold water tank 9 with a water storage function is also installed at the bottom of the water receiving bin 6. The ordinary hinged installation method cannot ensure that the water receiving bin 6 can rotate stably; therefore, an auxiliary rotating component 26 is arranged on the right side of the top of the base 2. When the auxiliary rotating component 26 is hinged to the front and rear sides of the right part of the water receiving bin 6, it can balance the supporting force of the water receiving bin 6, driving the water receiving bin 6 to rotate stably, and at the same time, it also gives the water receiving bin 6 the function of rotating, opening or closing according to instructions, without manual operation.

[0042] It can be understood that in this embodiment, the auxiliary rotating component 26 is specifically configured as the following components, but is not limited to the following components: a driving motor is provided on the front side of the base 2, the output shaft of the driving motor extends backward, and rocker arms are symmetrically arranged front and back, and the distance between the rocker arms is greater than the width of the water receiving bin 6. Then, after a spring is connected between the left end of the rocker arm and the water receiving bin 6, the driving motor can drive the rocker arm to rotate, and at the same time, under the traction force of the spring, the water receiving bin 6 is driven to swing, and the counterclockwise selection is for mold merging, and the clockwise selection is for the mold opening after the ice ball is made.

[0043] It should be noted that the spring here is a highly elastic and high-density designed spring, so that it can provide sufficient traction to the water receiving bin 6 while allowing the drive motor to have space for overload, to avoid the rocker arm rotating excessively, the lower mold 8 has been merged with the upper mold 4, and can no longer continue to rotate, resulting in damage to the resistance force. At this time, the spring can be stretched to a certain extent to protect the lower mold 8.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0045] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
