Description

Technical Field

[0001] This utility model belongs to the field of ice-making technology, specifically relating to an ice-making cavity that expands the refrigeration range. Background Technology

[0002] For ice makers, especially household or small commercial ice makers, cooling efficiency and ice-making speed are key performance indicators. Existing ice-making modules typically use an evaporator attached to the outer wall of the ice-making cavity for cooling. Common structures involve the evaporator covering only one side of the ice-making cavity (such as the bottom or rear), or using a partial wrapping method. This single-sided or partial contact cooling method results in a limited heat exchange area, preventing the uniform and efficient transfer of cooling energy to all parts of the ice-making cavity. Utility Model Content

[0003] The purpose of this invention is to provide an ice-making cavity that expands the refrigeration range, thereby solving the problem of refrigeration transfer efficiency in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An ice-making cavity for expanding the cooling range includes an ice-making module. The ice-making module includes a shell, an inner module, and a top plate. The inner module is fixed inside the shell. One side of the inner module has an ice-making cavity. The back of the ice-making cavity has an inner compartment. The top plate is sealed and fixed above the inner compartment. The inner compartment covers the outer wall of the ice-making cavity in all directions.

[0005] Preferably, the outer shell is made of thermal insulation material. The thermal insulation material is a combination of thermal insulation panels and foam. The inner module is made of thermally conductive material. The thermally conductive material is selected from copper or aluminum.

[0006] Reduced heat loss: The outer shell is made of insulating material, effectively blocking external heat from entering the ice-making cavity. This creates a relatively low and stable environment for the ice-making process, reducing energy loss due to heat exchange. This allows the temperature inside the ice-making cavity to drop below freezing point more quickly, accelerating water freezing and significantly improving ice-making efficiency. It also prevents external temperature fluctuations from interfering with the ice-making process, ensuring uniform and rapid ice formation and improving the stability and reliability of the ice-making process. The insulating material uses a combination of insulating panels and foam, or insulating panels and foam alone, such as rigid polyurethane foam (PU). Thermally conductive materials quickly dissipate heat from the ice-making cavity, accelerating the freezing process inside. The insulating outer shell reduces heat loss, lowering the energy required to maintain the low-temperature environment for ice making; the efficient thermal conductivity of the inner modules further accelerates the ice-making process, shortening the ice-making time and further reducing energy consumption. The combined effect of these two elements effectively improves the overall energy efficiency of the equipment and reduces operating costs.

[0007] Preferably, the ice-making cavity has a rectangular structure, and a plurality of equally spaced partitions are arranged within the ice-making cavity, dividing the ice-making cavity into at least two spaces. Dividing the ice-making cavity into two or more spaces allows ice-making operations to be performed simultaneously in different spaces. Compared to ice-making methods in a single large space, this increases the number of ice blocks that can be made simultaneously, producing more ice blocks in the same amount of time, significantly improving the overall efficiency of ice making and meeting the demand for large-scale ice consumption.

[0008] Preferably, a condensing pipe is installed on the top plate, the condensing pipe is connected to the inner compartment, and the condensing pipe includes an inlet condensing pipe and an outlet condensing pipe, wherein the inlet condensing pipe and the outlet condensing pipe are symmetrically arranged around the center of the liquid blocking block.

[0009] Preferably, a liquid-blocking block is fixed to the top outer wall of the ice-making cavity, the liquid-blocking block is centrally located, and the top plate is supported and fixed above the liquid-blocking block. The purpose of the liquid-blocking block is to symmetrically divide the inner compartment into two sets of spaces.

[0010] Preferably, the inner compartment and the top plate constitute a condensate storage space. This condensate storage space is formed by mirroring the liquid-blocking blocks to create an "L"-shaped space, with one end sealed by the liquid-blocking blocks. The condensate storage space represents the area in contact between the condensate and the ice-making cavity. The condensate transfers heat to the ice-making cavity through heat transfer, enabling the ice-making and de-icing processes. The "L"-shaped condensate storage space, divided by the liquid-blocking blocks, allows the condensate to completely surround the ice-making cavity, significantly increasing the heat conduction area and further improving the ice-making speed within the cavity. Since one end of the condensate storage space is sealed by the liquid-blocking blocks, while the other end is not sealed, the two "L"-shaped condensate storage spaces can fully contact the ice-making cavity while allowing for circulation and interaction. This facilitates the circulation and cooling or heating of the condensate through the inlet and outlet condensate pipes.

[0011] The technical solution of this utility model has the following beneficial effects: The inner compartment fully covers the outer wall of the ice-making cavity, allowing the refrigerant to cool the ice-making cavity from all directions. Compared with single-sided or partial coverage refrigeration methods, it can absorb heat in the ice-making cavity more evenly and quickly, significantly improving refrigeration efficiency and shortening ice-making time.

[0012] The inner compartment and the ice-making cavity are formed as an integral module, which means that the inner compartment and the ice-making cavity are closely connected to each other, thereby enhancing the heat exchange effect; at the same time, it also reduces the number of parts and connection points.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] Example 1: refer to Figures 1-7 An ice-making cavity for expanding the cooling range includes an ice-making module. The ice-making module includes a shell 101, an inner module 1011, and a top plate 106. The inner module 1011 is fixed inside the shell 101. One side of the inner module 1011 is provided with an ice-making cavity 102. The back of the ice-making cavity 102 is provided with an inner compartment 104. The top plate 106 is sealed and fixed above the inner compartment 104. The inner compartment 104 covers the outer wall of the ice-making cavity 102 in all directions.

[0024] In the above scheme, during the ice-making process, the ice is formed inside the ice-making cavity 102. The water spray system inside the ice maker sprays water into the ice-making cavity 102 to gradually make ice. The inner compartment 104 is the space for refrigerant flow. The inner compartment 104 covers the outer wall of the ice-making cavity 102 in all directions, allowing the refrigerant to cool the ice-making cavity 102 from all directions. Compared with single-sided or partial coverage refrigeration methods, it can absorb heat in the ice-making cavity 102 more evenly and quickly, significantly improving refrigeration efficiency and shortening ice-making time. Here, the inner compartment 104 and the ice-making cavity 102 are integrally formed as an inner module 1011. This means that the inner compartment 104 and the ice-making cavity 102 are closely fitted together, thereby enhancing the heat exchange effect. The integral formation as an inner module 1011 reduces the number of parts and connection points, making the overall structure simpler. This integrated design avoids problems such as loosening and uneven gaps that may occur when assembling multiple components, improving the structural strength and stability of the inner module 1011 and reducing the probability of equipment failure during use. Simultaneously, during the ice-making process, water can crystallize in a relatively uniform temperature environment, avoiding problems such as uneven ice density and large differences in transparency caused by local temperature differences, resulting in ice blocks that are more uniform in physical properties and of higher quality.

[0025] Preferably, the outer shell 101 is made of thermal insulation material.

[0026] In the preferred embodiment, heat loss is reduced: the outer shell 101 is made of insulating material, which effectively blocks external heat from being transferred into the ice-making cavity 102, creating a relatively low-temperature and stable environment for the ice-making process. This reduces energy loss due to heat exchange, allowing the temperature inside the ice-making cavity 102 to drop below the freezing point more quickly, thereby accelerating the freezing speed of water, significantly improving ice-making efficiency, avoiding interference from external temperature fluctuations on the ice-making process, ensuring that ice blocks can form uniformly and quickly, and improving the stability and reliability of ice making. The insulating material uses a combination of insulating panels and foam, or uses insulating panels and foam alone, such as rigid polyurethane foam (PU).

[0027] Preferably, the inner module 1011 is made of a thermally conductive material.

[0028] In the preferred embodiment, the thermally conductive material can rapidly dissipate heat from the ice-making cavity 102, thereby accelerating the icing process inside the ice-making cavity 102. The insulating outer shell 101 reduces heat loss, lowering the energy required to maintain the low-temperature environment for ice making; the efficient thermal conductivity of the inner module 1011 further accelerates the ice-making process, shortens the ice-making time, and further reduces energy consumption. The synergistic effect of both effectively improves the overall energy-saving performance of the equipment and reduces operating costs. The thermally conductive material is selected as copper or aluminum.

[0029] Preferably, the ice-making cavity 102 has a rectangular structure, and a plurality of equally spaced partition plates 103 are arranged inside the ice-making cavity 102, the partition plates 103 dividing the ice-making cavity 102 into at least two spaces.

[0030] In a preferred embodiment, the partition plate 103 divides the ice-making cavity 102 into two or more spaces, allowing ice-making operations to be performed simultaneously in different spaces. Compared to ice-making in a single large space, this increases the number of ice blocks that can be made simultaneously, producing more ice blocks in the same amount of time, significantly improving the overall efficiency of ice making and meeting the demand for large quantities of ice. The rectangular structure of the ice-making cavity 102, combined with the partition plate 103, facilitates a more rational distribution of cooling capacity in the refrigeration system, reduces ineffective diffusion of cooling energy, makes the refrigeration process more efficient, and further shortens the ice-making time.

[0031] Preferred reference Figures 3-6 A condensing pipe 107 is installed on the top plate 106, and the condensing pipe 107 is connected to the inner compartment 104. The condensing pipe 107 includes an inlet condensing pipe and an outlet condensing pipe, which are symmetrically arranged around the center of the liquid blocking block 105. It should be noted that: (The inlet condensing pipe is connected to the lower part of the condenser and is responsible for introducing low-temperature, low-pressure liquid refrigerant into the condenser. The outlet condensing pipe is connected to the upper part of the condenser and is responsible for exporting high-temperature, high-pressure gaseous refrigerant from the condenser. Specifically, it needs to work in conjunction with the compressor to continuously extract gaseous refrigerant from the evaporator and compress it into high-temperature, high-pressure gas, which is then sent to the condenser for condensation).

[0032] Preferred reference Figures 5-7 A liquid-blocking block 105 is fixed to the top outer wall of the ice-making cavity 102. The liquid-blocking block 105 is centrally located, and the top plate 106 is supported and fixed above the liquid-blocking block 105. The purpose of the liquid-blocking block 105 is to symmetrically divide the inner compartment 104 into two sets of spaces.

[0033] Preferred reference Figures 5-7 The inner compartment 104 and the top plate 106 form a condensate storage space. The condensate storage space is mirrored by the liquid blocking block 105 to form an "L" shaped space. Either end of the condensate storage space is closed by the liquid blocking block 105.

[0034] In the preferred embodiment, the condensate storage space is the area in contact between the condensate and the ice-making cavity 102. The condensate transfers heat to the ice-making cavity 102 via heat transfer to achieve the ice-making and de-icing processes. The "L"-shaped condensate storage space is divided by the liquid-blocking block 105 (see reference). Figure 5This allows the condensate to completely surround the ice-making cavity 102, significantly increasing the area for heat conduction and thus further improving the ice-making speed inside the ice-making cavity 102. Since one end of the condensate storage space is sealed by the liquid-blocking block 105, while the other end is not sealed (see reference...). Figure 7 In this way, the "L"-shaped condensate storage spaces on both sides can fully contact the ice-making cavity 102 while also enabling circulation and interaction, thus facilitating the circulation and cooling or heating of condensate through the inlet and outlet condensate pipes.
