Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ice makers, and particularly relates to an evaporation plate for an ice maker. Background Art
[0002] Evaporators are widely used in fields such as refrigeration and ice making. In an ice maker, high-pressure liquid refrigerant passes through an expansion valve or throttling device and rapidly expands to a low-pressure state and enters the evaporator. At this time, in the evaporator, the refrigerant expands and absorbs the surrounding heat, and the refrigerant evaporates into a gas. This process absorbs a large amount of heat, causing the temperature of the evaporator surface to decrease.
[0003] Conversely, in an ice maker, the compressor compresses the low-pressure and low-temperature refrigerant gas into a high-pressure and hot gas, and through a reversing valve, the high-pressure and hot gas enters the evaporator. At this time, the surface of the evaporator releases heat and the temperature rises.
[0004] The evaporator used in an ice maker includes two major structures, namely a base plate and a condensing pipe. The base plate is provided with a plurality of small molds, and the base plate and the molds are integrally formed. In the existing evaporator, the condensing pipe is directly welded and fixed to the base plate. When the mold needs to be replaced, the whole needs to be replaced. However, this process requires cutting off the connection between the condensing pipe and the refrigerant, and requires professional workers to operate to prevent refrigerant leakage. Moreover, when installing, the connection between the condensing pipe and the refrigerant needs to be welded, and the whole operation process is very complicated, time-consuming and laborious, affecting production efficiency. Content of the Utility Model
[0005] The purpose of the utility model is to provide an evaporation plate for an ice maker to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solution: An evaporation plate for an ice maker, including a base plate and a condensing pipe, the base plate fixedly installs the condensing pipe through a pressing plate, the pressing plate includes a fixed section and a pressing section, the fixed section is fixedly connected to the base plate through bolts, the base plate is provided with assembly holes, and the assembly holes are fixedly connected with connecting pieces.
[0007] Preferably, the base plate is provided with an assembly groove, and the assembly groove fixedly installs the condensing pipe.
[0008] Preferably, the assembly groove is an arc-shaped groove with a radius of R, and the outer diameter of the condensing pipe is equal to R.
[0009] Preferably, the base plate is provided with an ice-making mold, and the ice-making mold is provided with a pressure relief hole.
[0010] Preferably, the base plate is provided with a temperature measurement hole, and a temperature sensor is fixedly installed in the temperature measurement hole.
[0011] Preferably, the material of the condensing pipe is stainless steel.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] In the present utility model, the condensing pipe is fixed on the substrate through a pressing plate. The pressing plate and the substrate are fixed by bolts. An assembly groove is also provided on the substrate, and the condensing pipe is installed inside the assembly groove, which increases the contact area between the condensing pipe and the substrate and improves the heat transfer efficiency between the condensing pipe and the substrate. When the mold needs to be replaced, the bolts are removed to loosen the pressing plate, and the substrate can be quickly removed. When installing the mold, the condensing pipe is quickly placed into the assembly groove of the substrate, then the pressing plate is installed, and it is fixed on the substrate by bolts to complete the mold replacement, shortening the downtime of the ice maker and improving the production efficiency.
[0014] In the traditional evaporator, the condensing pipe is directly welded and fixed on the substrate. The welding process causes local high temperature of the substrate, resulting in irreversible deformation of the substrate. As a result, the ice-making mold on the substrate cannot be fully fitted during mold closing, leading to water leakage in the mold combination after mold closing, and the ice cubes formed by the ice-making mold cannot be fully filled and saturated, resulting in a decline in the quality of the ice cubes. In the present invention, the condensing pipe is fixed on the substrate through a pressing plate, and the bolt fixing method is used to prevent the substrate from deforming, ensuring that the ice-making mold on the substrate is fully fitted during mold closing and improving the quality of the ice cubes.

DETAILED DESCRIPTION OF THE INVENTION
[0024] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in these embodiments will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.
[0025] Embodiment 1:
[0026] As Figures 1 - 8 shown, an evaporation plate for an ice maker provided by the present utility model includes a substrate 1 and a condensation pipe 2. The substrate 1 fixedly installs the condensation pipe 2 through a pressing plate 3. The pressing plate 3 includes a fixing section 4 and a pressing section 5. The fixing section 4 is fixedly connected to the substrate 1 through a bolt 6. The substrate 1 is provided with an assembly hole 7, and a connecting piece 8 is fixedly connected to the assembly hole 7. The substrate 1 is provided with an assembly groove 9, and the condensation pipe 2 is fixedly installed in the assembly groove 9. The assembly groove 9 is a circular arc groove with a radius of R, and the outer diameter of the condensation pipe 2 is equal to R. The substrate 1 is provided with an ice making mold 10, and the ice making mold 10 is provided with a pressure relief hole 11. The substrate 1 is provided with a temperature measuring hole 12, and a temperature sensor 13 is fixedly installed in the temperature measuring hole 12. The material of the condensation pipe 2 is stainless steel.
[0027] Through the above technical solution, in the present utility model, the condensation pipe 2 is fixed on the substrate 1 through the pressing plate 3. The pressing plate 3 and the substrate 1 are fixed through the bolt 6. An assembly groove 9 is also provided on the substrate 1, and the condensation pipe 2 is installed inside the assembly groove 9, which increases the contact area between the condensation pipe 2 and the substrate 1 and improves the heat transfer efficiency between the condensation pipe 2 and the substrate 1. When the mold needs to be replaced, by removing the bolt 6, the pressing plate 3 is loosened, and the substrate 1 can be quickly removed. When installing the mold, the condensation pipe 2 is quickly placed into the assembly groove 9 of the substrate 1, then the pressing plate 3 is installed, and it is fixed on the substrate 1 through the bolt 6 to complete the mold replacement, shortening the shutdown time of the ice maker and improving production efficiency.
[0028] In the traditional evaporator, the condensation pipe 2 is directly welded and fixed on the substrate 1. The welding process makes the local temperature of the substrate 1 high, resulting in irreversible deformation of the substrate 1, causing the ice making mold 10 on the substrate 1 not to fit completely during mold closing, resulting in water leakage in the mold combination after mold closing, causing the ice cubes formed by the ice making mold 10 not to be fully filled and saturated, and resulting in a decrease in the quality of the ice cubes. In the present invention, the condensation pipe 2 is fixed on the substrate 1 through the pressing plate 3, and the bolt 6 fixing method is used to prevent the substrate 1 from deforming, ensuring that the ice making mold 10 on the substrate 1 fits completely during mold closing and improving the quality of the ice cubes.
[0029] Embodiment 2:
[0030] As Figures 1 - 8As shown in the figure, the connection method between the substrate 1 and the condenser tube 2 of the present utility model adopts a scheme of fixing with a pressing plate 3. The pressing plate 3 includes two main parts: a fixing section 4 and a pressing section 5. The fixing section 4 is provided with through holes, and the fixing section 4 is connected to the substrate 1 through bolts 6 (during this process, the bolts 6 pass through), ensuring that the pressing plate 3 can be firmly fixed on the substrate 1. The pressing section 5 is used to press the condenser tube 2, so that the condenser tube 2 is fixed on the substrate 1. Such a design can effectively prevent the condenser tube 2 from loosening during use due to vibration or external force, improve the heat exchange performance between the condenser tube 2 and the substrate 1, and thus ensure the stability and efficiency of the refrigeration system. A plurality of assembly holes 7 are provided on the substrate 1, and the function of these assembly holes 7 is to install connectors 8. The evaporation plate of the present utility model is fixed on the ice maker through the connectors 8. The connectors 8 can also reduce the direct heat exchange between the evaporation plate and the ice maker. If there is direct heat exchange, it will affect the refrigeration efficiency of the evaporation plate. Therefore, through the design of the connectors 8, the direct heat exchange between the evaporation plate and the ice maker is reduced, and the refrigeration efficiency of the ice maker is improved. The connector 8 is of a screw structure, and the assembly hole 7 is of a threaded hole structure, and is installed by screwing, making the installation and disassembly of the condenser tube 2 more convenient. The pressing plate 3 fixes the condenser tube 2 on the substrate 1 through bolts 6. When it is necessary to replace the mold (the mold and the substrate 1 are an integrated structure) or perform maintenance, only the bolts 6 on the pressing plate 3 need to be loosened to disassemble the condenser tube 2, without the need to replace the entire evaporator. This improvement significantly reduces the complexity of the operation process, reduces the dependence on professional workers, and also reduces the risk of refrigerant leakage. The present utility model also has good economy and practicability. Since the condenser tube 2 can be replaced independently of the substrate 1, the manufacturing and maintenance costs are effectively controlled. The traditional welding method not only has a high cost but also requires a long downtime. The new fixing scheme makes the replacement process faster, reduces the downtime, and thus improves the production efficiency. In practical applications, the present utility model can effectively improve the overall operating efficiency and reliability of the ice maker. The separated design of the substrate 1 and the condenser tube 2 also brings better flexibility. Different types of condenser tubes 2 can be selected and installed according to actual needs, which provides a greater space for the customization and function optimization of the ice maker. By using condenser tubes 2 of different materials, the requirements for different refrigeration equipment can be met. The present utility model simplifies the operation process, reduces the maintenance cost, and improves the production efficiency by changing the connection method between the condenser tube 2 and the substrate 1 from traditional welding to fixing with the pressing plate 3. The design of the assembly holes 7 and the connectors 8 on the substrate 1 makes the installation and replacement of the condenser tube 2 more convenient, further improving the flexibility and reliability of the system.
[0031] The utility model further optimizes the connection mode between the substrate 1 and the condensing pipe 2. An assembly groove 9 is provided on the substrate 1, and the condensing pipe 2 is installed in the assembly groove 9, which increases the contact area between the condensing pipe 2 and the substrate 1, thereby improving the heat transfer efficiency between the condensing pipe 2 and the substrate 1. The size and shape of the assembly groove 9 match those of the condensing pipe 2, ensuring that the condensing pipe 2 can be completely embedded in the groove to form a tight contact surface, increasing the contact area between the condensing pipe 2 and the substrate 1, and improving the heat transfer efficiency between the condensing pipe 2 and the substrate 1. During the operation of the ice maker, the main function of the condensing pipe 2 is to pass a cooling refrigerant to absorb or release heat, enabling the evaporation plate to achieve the refrigeration or heating function. When the evaporation plate is refrigerating, the refrigerant in the condensing pipe 2 absorbs the heat on the substrate 1, reducing the temperature of the substrate 1, so that the water in the mold freezes, completing the ice-making process; when the evaporation plate is heating, the reversing valve of the ice maker switches to pass a high-temperature and high-pressure refrigerant into the condensing pipe 2. At this time, the condensing pipe 2 transfers heat to the substrate 1, raising the temperature of the mold and melting the connection surface between the ice block and the mold, quickly completing the ice block demolding. In this process, the size of the contact area directly affects the heat transfer efficiency. Through the design of the assembly groove 9, the contact area between the condensing pipe 2 and the substrate 1 can be maximized, thereby improving the heat exchange effect. This improvement not only optimizes the refrigeration effect but also enhances the overall working efficiency of the ice maker. The setting of the assembly groove 9 can also reduce the thermal resistance generated due to poor contact between the condensing pipe 2 and the substrate 1. The assembly groove 9 reduces the thermal resistance and improves the reliability of heat transfer by providing a stable and uniform contact surface. The assembly groove 9 also has a certain mechanical support function. After the condensing pipe 2 is installed in the assembly groove 9, it has better mechanical stability, preventing displacement due to vibration or other external forces during use. During the replacement and maintenance process, since the assembly groove 9 can provide accurate positioning, the installation of the condensing pipe 2 becomes simpler. When replacement or maintenance is required, the condensing pipe 2 can be conveniently removed from or reinstalled in the assembly groove 9, eliminating complex adjustment or alignment operations, reducing the operation difficulty, and improving the production efficiency and maintenance efficiency.
[0032] The assembly groove 9 of the utility model is an arc-shaped groove with a radius of R, and the radius R of the assembly groove 9 is equal to the outer diameter of the condenser 2. The outer wall of the condenser 2 is closely fitted with the assembly groove 9 to further improve the heat transfer efficiency. The condenser 2 is a cylindrical pipe, and the arc-shaped groove can effectively increase the contact area between the condenser 2 and the substrate 1. Specifically, the arc-shaped groove with a radius of R provides a contact surface that matches the outer diameter of the condenser 2, so that the outer wall of the condenser 2 can completely fit the inner wall of the groove. The contact area between the condenser 2 and the substrate 1 is increased, thereby improving the heat transfer efficiency. The outer diameter of the condenser 2 is equal to the radius R of the assembly groove 9, so that the outer wall of the condenser 2 can form an arc contact surface with the assembly groove 9. Through this close contact, heat can be transferred between the condenser 2 and the substrate 1 more efficiently. During the refrigeration process of the condenser 2, the cooling or heating effect of the refrigerant needs to effectively exchange heat with the substrate 1 through its outer wall. Reduce the thermal resistance caused by poor contact and improve the performance of the refrigeration system. The arc-shaped groove design also has excellent mechanical stability. The condenser tube 2 is stably supported in the arc-shaped groove, avoiding displacement of the tube due to mechanical vibration or improper operation. The arc-shaped groove can evenly distribute the mechanical pressure, so that the position of the condenser tube 2 in the groove remains stable, which not only improves the contact quality between the condenser tube 2 and the substrate 1, but also reduces the poor contact phenomenon caused by long-term use, further improving the durability and reliability of the equipment.
[0033] Embodiment three:
[0034] like Figures 1 - 8 As shown, the ice-making mold 10 of the utility model is provided with a pressure relief hole 11. This design mainly solves the problem of the mold opening caused by the volume expansion of water during the freezing process, thereby improving the quality of ice cubes. The volume of water will expand during the freezing process. This characteristic is due to the fact that when water molecules change from liquid to solid during freezing, a relatively open crystal structure is formed, resulting in an increase in volume. The volume expansion exerts direct mechanical pressure on the ice-making mold 10. If the structure of the ice-making mold 10 fails to effectively cope with this pressure, the mold will be stretched open, resulting in the shape and quality of the ice cube being affected. The utility model is provided with a pressure relief hole 11 in the ice-making mold 10. The main function of the pressure relief hole 11 is to ensure that the pressure generated during the water freezing process can be released in time by controlling and releasing the pressure inside the ice-making mold 10, thereby preventing the mold from being stretched open due to volume expansion.
[0035] On the substrate 1 of the present utility model, a temperature measuring hole 12 is provided, and a temperature sensor is fixedly installed in the temperature measuring hole 12. Through the temperature measuring hole 12 on the substrate 1, a completely fitting contact is formed between the temperature sensor and the substrate 1, thereby improving the accuracy of the temperature sensor in obtaining the temperature of the substrate 1 and making the ice maker control the temperature of the evaporation plate more precisely. During the operation of the ice maker, the temperature of the evaporation plate is a key parameter. The working effect of the ice maker and the quality of the ice cubes are directly affected by the temperature of the evaporation plate. Therefore, accurately measuring and controlling the temperature of the evaporation plate is crucial for improving the performance and ice-making efficiency of the ice maker. By providing a temperature measuring hole 12 on the substrate 1 and installing a temperature sensor in the temperature measuring hole 12, the actual temperature data of the evaporation plate can be accurately obtained, and the ice maker can perform accurate temperature control based on these temperature data. The temperature measuring hole 12 enables the temperature sensor to be in close contact with the substrate 1, ensuring that the sensor can accurately obtain the actual temperature of the substrate 1. Traditional temperature measurement methods have deviations in measurement data due to insufficient contact between the sensor and the measurement surface or the existence of air gaps. By providing a temperature measuring hole 12 on the substrate 1 and fixing the temperature sensor in the hole, these potential error sources can be reduced, enabling the sensor to obtain the temperature information of the substrate 1 more directly and accurately. In addition, the design of the temperature measuring hole 12 also helps with the maintenance and replacement of the temperature sensor. Since the temperature measuring hole 12 provides a convenient installation position, maintenance personnel can easily access the sensor for repair or replacement without having to disassemble the entire evaporation plate or perform complex operations. This design not only improves the maintenance efficiency but also reduces the operation difficulty and downtime, thereby improving the overall operating efficiency of the ice maker.
[0036] The material of the condenser tube 2 of the present utility model is stainless steel. The stainless steel material mainly meets the requirement that when the ice maker switches to the heating mode, in the heating mode of the evaporation plate, a high-temperature and high-pressure refrigerant gas is introduced into the condenser tube 2. Therefore, the condenser tube 2 needs to use a material that can withstand high pressure and temperature to ensure the safety and stability of the equipment.
[0037] The pressing plate 3 of the present utility model is divided into two types. One type is composed of one pressing section 5 and two fixing sections 4 (as Figure 7 shown), and this design is convenient for flexible installation; the other type is composed of multiple pressing sections 5 and multiple fixing sections 4 (as Figure 8 shown), which can fix multiple sections of the condenser tube 2 simultaneously and improve the installation speed.
[0038] It should be noted that in this text, 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 "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.
