Description

Technical Field

[0001] The utility model belongs to the technical field of ice makers, and particularly relates to a defrosting structure. Background Technique

[0002] An ice maker is a refrigeration mechanical device that generates ice by cooling water through an evaporator with a refrigerant. Mainly during the continuous circulation of chilled water through a water pump flowing through the evaporator, it drives the compressor to operate. Through a series of processes, it drives the chilled water to evaporate and absorb heat and vaporize at a low temperature of -10 to -18 degrees under the influence of the evaporator, and gradually condenses into an ice layer. After ice making is completed, the defrost solenoid valve or other common heat pumps are turned on, and the high-pressure hot gas discharged from the compressor replaces the refrigerant through the reversing valve and is diverted to the evaporator. Through heat transfer, the surface of the ice cube melts, forming a water film to separate the ice cube from the evaporator. Then, the ice cube naturally drops by gravity to complete the collection of the ice cube.

[0003] However, in the production of ice balls, common ice-making molds are assembled by splicing up and down. At the same time, since the evaporator is generally installed at the inner top of the box body, it will be connected to the upper mold, and then drive the lower mold to flip to complete the opening of the ice ball mold. However, after the mold is filled with water and freezes, the lower mold will adhere to the ice ball, making it impossible to quickly open the lower mold, affecting the ice-making efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a defrosting structure for an ice maker to solve the problems raised in the above background technique.

[0011] Preferably, the lower inner cavity of the main bin forms the water storage tank. A vertical groove is formed on the left side of the main bin, and a connecting water pipe is installed in the vertical groove.

Since the water injection hole is the lowest horizontal position of the entire spherical mold, the flowing water can be sprayed upward through the water injection hole to contact the lower surface of the ice ball, bringing continuous heat energy supply, so that the lower surface of the ice ball can be melted to separate it from the adhesion with the lower mold; after the lower mold is separated from the upper mold, the ice ball hangs in the upper mold. At this time, by heating the evaporation plate at the top of the upper mold, the adhesion between the ice ball and the upper mold can be driven, and the ice ball will naturally fall downward to complete ice removal; at the same time, a plurality of filter holes are formed in the bottom plate of the storage refrigerator to quickly filter the water on the surface of the ice ball downward to avoid ice ball adhesion; the above are all for achieving high-quality ice removal. In practical applications, the use of water circulation can also reduce a certain amount of water resource waste problems and reduce the ice making cost, and has broad application value in the future ice making machine market.

[0026] The utility model cooperates with ice making by setting a spherical mold formed by splicing the upper and lower molds 8, and setting a water circulation component, so that the flowing water continuously flows upward through the lower part of the main compartment 1.

At this time, the evaporation plate 4 on the top of the upper mold 3 generates heat to drive the adhesion of the ice ball to the upper mold 3, and naturally falls downward to complete ice removal; at the same time, a plurality of filter holes 17 are opened on the bottom plate 16 of the ice storage refrigerator 15, which are used to quickly filter the water on the surface of the ice ball downward to avoid the adhesion of the ice ball; all of the above are for achieving high-quality ice removal. In practical applications, the use of water circulation can also reduce a certain waste of water resources and reduce the cost of ice making. It has a wide range of use value in the future ice making machine market.

[0027] Example 2

[0028] like Figures 1 to 7An ice-making machine ice-detaching structure shown in the figure includes a main bin 1. The main bin 1 is used to surround and protect the internal components of the ice-making machine, ensuring the maintenance of the internal environment during ice-making, preventing pollutants such as dust from entering the main bin 1 and affecting the appearance of the formed ice cubes. On the upper inner wall of the main bin 1, a base 2 is installed. On the right side of the bottom of the base 2, there is an upper mold 3. At the bottom of the upper mold 3, there are multiple semi-spherical ice-making grooves, specifically in a 4*7 quantity template. Correspondingly, on the left side of the bottom of the base 2, hinge seats 5 are symmetrically arranged. Between the left sides of the hinge seats 5, a water receiving bin 6 is hinged. On the top of the water receiving bin 6, a lower mold 8 is installed through multiple mounting card seats 7. On the top of the lower mold 8, there are also 4*7 semi-spherical ice-making grooves. Then, when the water receiving bin 6 rotates, driving the lower mold 8 to be spliced with the upper mold 3 into one body, a spherical ice-making mold can be formed.

[0029] The number of mounting card seats 7 is the same as the number of spherical molds, and they are all located at the lowest horizontal position of the entire spherical mold. When a water injection hole 9 is opened in the middle of the mounting card seat 7, the flowing water in the water receiving bin 6 can be sprayed upward through the water injection hole 9 into the spherical mold. At this time, affected by the cooling part at the top of the upper mold 3, the water entering starts to solidify gradually downward from the top inner wall of the upper mold 3 to complete ice-making.

[0030] Among them, due to a certain volume existing in the water receiving bin 6 itself, and the weight after the ice ball solidifies, the water receiving bin 6 rotatably connected only through the hinge seats 5 is not stable enough. The movement of the water receiving bin 6 will cause the formed ice ball to have an empty bin and crack. Therefore, on the right side of the inner wall of the main bin 1, at a position below the base 2, there are two stabilizing arms 11. The stabilizing arms 11 are hinged to the front and rear sides of the right part of the water receiving bin 6 respectively. The stabilizing arm 11 is composed of two folding shafts 111 and is driven by a control chip (not shown in the figure). In the initial state, the stabilizing arm 11 is in a fully extended state. When ice-making is required, the control chip will drive the upper folding shaft 111 to fold leftward to be parallel to the upper mold 3, and at the same time drive the lower folding shaft 111 to fold rightward to also be parallel to the upper mold 3. At this time, the two stabilizing arms 11 are in a parallel folding state, driving the water receiving bin 6 to rotate counterclockwise, and the lower mold 8 is spliced with the upper mold 3 to form a spherical mold to cooperate with ice-making. Among them, a rigid spring 112 is sleeved on the folding shaft 111 close to the water receiving bin 6 to prevent the stabilizing arm 11 from overfolding.

[0031] Furthermore, after ice-making is completed, the stabilizing arm 11 needs to be extended again, driving the water receiving bin 6 to rotate clockwise, and the lower mold 8 is separated from the upper mold 3. The ice ball hangs in the upper mold 3. At this time, relying on the evaporation plate 4 at the top of the upper mold 3 to generate heat, the heat is transferred through the upper mold 3 to the position where its inner wall contacts the ice ball, and the surface of the ice ball melts, detaching from the adhesion with the upper mold 3 and naturally falling downward.

[0032] On both the left and right sides at the lower part of the main bin 1, there are installation tracks 14 for slidably installing the ice ball storage box 15. The ice ball storage box 15 is mainly used for collecting and storing the dropped ice balls. It is easy to know that when the surface of the ice ball melts, water will definitely be generated, which means that the surface temperature of the ice ball has dropped below 0°C at this time, while the internal temperature of the ice ball is still very low. As a result, this water will re-freeze into ice on the surface of the ice ball. When the ice balls in the ice ball storage box 15 are stacked together, they will stick the ice balls together, and secondary treatment is required later to separate the ice balls, which is an unnecessary production cost.

[0033] Therefore, the bottom plate 16 of the ice ball storage box 15 is separately described. A plurality of filter holes 17 are opened on the bottom plate 16 for quickly filtering the water on the surface of the ice ball downward to avoid the adhesion of the ice balls. At the same time, the left side of the bottom plate 16 is an inclined plate 161, and the right side is a horizontal plate 162. Then, when the ice balls fall downward into the ice ball storage box 15 and accumulate to a certain number, the ice ball storage box 15 can be pulled forward along the installation track 14 until it is separated from the main bin 1. Subsequently, one side of the inclined plate 161 is further inclined to the left, so that the ice balls slide out to the left guided by the inclined plate 161, which is convenient for collection and can also avoid damage caused by the direct pouring out of the ice balls.

[0034] Embodiment 3

[0035] As Figures 1 to 7 shown in an ice-making machine ice-removing structure, the stable arm 11 operates to drive the lower mold 8 and the upper mold 3 to be spliced to form a spherical mold. Then, the flowing water in the water receiving bin 6 is sprayed upward through the water injection hole 9 into the spherical mold. At this time, under the cooling member at the top of the upper mold 3, the water entering starts to solidify gradually downward from the inner wall top of the upper mold 3 to complete ice-making. When removing the ice, the lower mold 8 is rotated and opened. However, at this time, the lower mold 8 will adhere to the lower surface of the ice ball. If the stable arm 11 forces the lower mold 8 to be opened, but this adhesion surface is at the water injection hole 9, directly opening it will instead cause the ice ball to crack and be damaged. Therefore, a method of using circulating water for ice removal is designed.

[0036] A cold water tank 12 is installed at the bottom of the water receiving bin 6. A water injection assembly 13 is connected between the cold water tank 12 and the bottom of the water receiving bin 6. The water injection assembly 13 communicates with the water injection hole 9. Thus, the flowing water in the cold water tank 12 can be driven by the water injection assembly 13 to drive the flowing water to be injected upward into the mounting seat 7 through the water injection hole 9, and then flow into the space between the lower mold 8 and the lower surface of the ice ball. It is known that flowing water is usually warmer than the ambient temperature of the ice ball. This temperature difference will cause heat exchange between the water and the surface of the ice ball. Then, by continuously circulating the flowing water, making it continuously contact the lower surface of the ice ball and bringing continuous heat energy supply, the lower surface of the ice ball can be melted, so that it is separated from the adhesion with the lower mold 8. At the same time, the flowing water can also wash away the melted ice water from the lower surface of the ice ball to prevent the melted ice water from refreezing. After the ice ball is no longer adhered to the lower mold 8, the stabilizing arm 11 is driven to extend again, the water receiving bin 6 rotates clockwise, the lower mold 8 is separated from the upper mold 3, and the ice ball is suspended in the upper mold 3. At this time, the evaporation plate 4 at the top of the upper mold 3 generates heat, and the heat is transferred to the position where the inner wall of the upper mold 3 contacts the ice ball through the upper mold 3. Melting occurs on the surface of the ice ball, and it is separated from the adhesion with the upper mold 3 and naturally falls downward into the storage refrigerator 15 to wait for collection.

[0037] Embodiment 4

[0038] On the basis of Embodiment 3, a water circulation assembly is provided. The lower inner wall of the main bin 1 forms a water storage tank 101. At the same time, a water pump 102 is embedded at the bottom of the main bin 1. The rear side of the water pump 102 communicates with the water storage tank 101 for pumping out the water in the water storage tank 101 for use. A vertical groove 103 is opened on the left side of the main bin 1. A connecting water pipe 104 is installed in the vertical groove 103. The connecting water pipe 104 is connected upward to a water sprinkling pipe 105. The other end of the water sprinkling pipe 105 passes through the main bin 1 and is located above the water receiving bin 6. Thus, when the lower end of the connecting water pipe 104 is connected to the water pump 102, the water pump 102 can operate to pump the water in the water storage tank 101 upward into the water sprinkling pipe 105 through the connecting water pipe 104. At this time, the flowing water moves from the lower part of the main bin 1 to the upper part of the main bin 1.

[0039] The water sprinkling pipe 105 is also fixedly connected to the hinge seat 5. Then, a plurality of water sprinkling holes 106 are opened at the bottom of the water sprinkling pipe 105. The water flowing to the upper part of the main bin 1 can be sprinkled downward into the water receiving bin 6 through the water sprinkling holes 106, and then enter the cold water tank 12 through a plurality of water leakage holes 107 on the right side of the top of the water receiving bin 6. The water injection assembly 13 in the cold water tank 12 operates to spray the water through the water injection hole 9, inject it into the mounting seat 7, and then flow into the space between the lower mold 8 and the lower surface of the ice ball. The continuous operation of the water pump 102 can drive the water to be continuously injected upward into the cold water tank 12, that is, the flowing water will continuously flow into the space between the lower mold 8 and the lower surface of the ice ball to melt the lower surface of the ice ball and achieve the effect of deicing.

[0040] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
