Description

Technical Field

[0001] The invention relates to the technical field of ice making machines, in particular to an instant household ice cube making device. Background Art

[0002] The cube ice machine is an efficient and reliable ice-making equipment that can quickly produce a large amount of cube ice and is suitable for various commercial places and home use. First of all, the cube ice machine can quickly reduce the temperature, quickly cool water and convert it into hard cube ice. Whether it is making cold drinks or refrigerating food, the cube ice machine can meet the needs. It is available in a variety of specifications and capacities, and can be customized according to the needs of users to ensure that it can meet the cube ice needs of different places. Secondly, the cube ice machine is simple and convenient to operate. Just pour water into the machine, set the required cube ice size and quantity, and press the button to start ice making. Users can adjust the size of the cube ice as needed to meet different usage needs. In addition, the cube ice machine also has an automatic cleaning function that can automatically clean the inside of the ice machine to keep the equipment hygienic and in good working condition. The cube ice machine has a fast ice-making speed and can produce a large amount of cube ice in a short time. This is especially important for commercial places that need to make a large amount of ice, such as hotels, restaurants and supermarkets. At the same time, the cube ice made by the cube ice machine is of uniform quality, and both the size and density are very balanced, which can ensure the quality and use effect of the cube ice.

[0003] However, the square ice cubes usually produced by the existing ice cube manufacturing equipment are solid. Since the solid square ice cubes are a whole piece of ice, the temperature inside is low, resulting in a slow melting speed. If rapid cooling or de-icing is required, the solid square ice cubes take a long time to completely melt, which is not applicable for some time-sensitive occasions. In addition, the solid square ice cubes are difficult to fully mix with the liquid during use. Due to the large shape of the solid ice cubes, it is not easy to melt quickly and fully contact the liquid, resulting in an unsatisfactory cooling effect. In some occasions where rapid cooling is required, such as making cold drinks or refrigerated foods, the solid square ice cubes cannot quickly reduce the temperature to the required level. In addition, the solid square ice cubes are large and have a high density, which is not easy to carry and store. In some occasions where ice cubes need to be moved or frequently used, such as outdoor picnics, camping activities, etc., the solid square ice cubes are inconvenient to carry and use.

[0006] Preferably, a heat conducting pipe 1 is embedded in the inner wall of the ice pressing bin, and the heat conducting pipe 1 is connected to the heat dissipation pipe of the compressor. A heat conducting pipe 2 is arranged in the ice pressing plate, and the heat conducting pipe 2 is connected to the heat dissipation pipe of the compressor.

[0007] Preferably, a slope is provided at the connection between the ice pressing bin and the ice outlet, and a height sensor for monitoring the amount of ice in the ice pressing bin is provided at the bottom of the slope.

[0008] Preferably, the rotating shaft passes through the bottom end surface of the ice bucket, a driving motor for driving the rotating shaft to rotate is arranged at the bottom end of the rotating shaft, the driving motor is connected to the rotating shaft through a transmission belt, a fixing plate is arranged on the top of the driving motor, and the fixing plate is fixed to the casing.

[0009] Preferably, the annular diameter of the water outlet is smaller than the top diameter of the ice bucket, the top diameter of the ice bucket is larger than the bottom diameter, the refrigeration pipe is arranged in a spiral shape along the outer wall of the ice bucket, and the cross-sectional shape of the refrigeration pipe is arranged to be circular or square.

[0010] Preferably, an annular reflux groove is also provided at the bottom of the ice bucket, a filter is provided between the reflux groove and the ice bucket, a reflux pipe is connected to the bottom of the reflux groove to return the water stored therein to the water storage tank, and a water pump module is provided on the reflux pipe.

[0011] Preferably, a door which is rotated by electric control is opened at the bottom of the ice pressing bin, and the door is symmetrically arranged on both sides of the bottom of the ice pressing bin, and the size of the door is larger than the size of the ice cubes pressed by the ice pressing plate.

[0012] Preferably, the ice pushing direction of the ice pushing plate is toward the ice outlet.

[0013] Preferably, an ice box for storing ice cubes is provided at the bottom of the door.

[0014] (III) Beneficial effects: Compared with the prior art, the present invention provides an instant household ice cube manufacturing device, which has the following beneficial effects:

[0015] 1. The instant household ice cube manufacturing device uses an ice bucket structure and an ice pressing bin structure in combination. Compared with the traditional technical structure, the ice cubes produced by this structure have some tiny gaps formed when the frost condenses. When the frost contacts each other, these tiny gaps will be connected to each other, so that there are some gaps and intervals between the ice, forming a loose structure. This loose ice cube structure makes the ice cube looser and easier to break. When the ice cube is placed in a liquid, the liquid will enter the ice cube through the gaps and contact with more surfaces of the ice cube. Heat is often transferred from the liquid to the ice cube by conduction. Since the loose structure increases the contact area between the ice cube and the liquid, the efficiency of heat transfer will also increase accordingly. Therefore, the ice cube with a loose structure can melt faster, and the loose structure of this soft ice can make the ice cube softer and easier to scrape, thereby increasing the taste of the ice cube and its melting speed and cooling speed.

[0016] 2. The instant household ice cube making device uses an ice scraper plate structure, an ice outlet structure, and an ice pressing bin structure in coordination. Compared with the traditional technical structure, the structure uses the movement of the piston module and the push rod to continuously push and compress the frost pile in the ice pressing bin to form ice cubes. When the ice cubes on one side are formed, they fall into the ice box through the rotation of the bin door. In this process, since the ice outlet continuously discharges ice, a new frost pile will be formed on the other side of the ice pressing plate. When the ice pressing plate moves in the opposite direction, the frost accumulated on the other side will continue to be compressed and moved to form new ice cubes. This continuous ice cube making process reduces the idle time of ice making and improves the ice making efficiency of the device.

[0017] 3. The instant household ice cube manufacturing device uses an ice bucket structure, an ice scraper structure, and an ice pressing bin structure in combination. Compared with the traditional technical structure, when the speed of the ice scraper in the structure decreases, the water will adhere to the surface of the ice bucket for a longer time to form normal ice flakes. Since the ice flakes formed in the round barrel itself have a certain curvature, when the curved ice is pressed into ice cubes by the ice pressing bin, its curved surface makes the gaps on its inner wall larger. When placed in a liquid, its contact area with the liquid is larger than that of ordinary ice cubes, and the heat exchange efficiency is higher. In addition, due to the large number of gaps on the inner wall, its density is reduced, and compared with traditional ice cubes of the same volume, its weight is lower and it is easier to carry.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The instant household ice cube making device comprises an ice bucket 4, a water storage tank 2, a compressor 3, and a casing 1, wherein the ice bucket 4 is arranged in the casing 1. Figure 6 , Figure 7 , Figure 8 As shown, the ice bucket 4 is the main space for making ice, and the inner surface of the ice bucket 4 is made of materials with good thermal conductivity and frost resistance. Stainless steel has good thermal conductivity and can quickly transfer the temperature of the coolant in the refrigeration tube 6 to the inner surface of the ice bucket 4, thereby promoting the condensation of frost. In addition, the surface of stainless steel is usually smooth and not easy to adhere to frost, which can make it easier to scrape frost and improve ice making efficiency. In addition, an ice bucket 4 with a ceramic coating can also be selected. The ceramic coating can effectively improve the smoothness of the surface of the ice bucket 4, reduce the adhesion of frost, and facilitate scraping. At the same time, the ceramic coating also has good thermal conductivity, which helps the temperature of the coolant to be quickly transferred to the surface of the ice bucket 4, promoting the condensation of frost. A water storage tank 2 is fixedly installed on the top of the ice bucket 4, and an annular water outlet 5 is opened at the bottom edge of the water storage tank 2. The water storage tank 2 is a water supply source in the instant household ice cube making device, and has the function of storing water and controlling water flow. A refrigeration pipe 6 is embedded in the inner wall of the ice bucket 4, and the refrigeration pipe 6 is connected to the compressor 3. The ice bucket 4 is arranged in a truncated cone shape. Fig. 9As shown, the truncated cone-shaped inclined surface can make the water flow stay on its surface longer than the vertical surface. When the water flows up and down the inclined surface, due to the inclination angle of the inclined surface, the speed of the water flow is relatively slow, so that the time the water flow stays on the inclined surface is increased, which is conducive to the interaction between water molecules, so that the coagulation force between water molecules is enhanced, so that it is easier to condense into ice on the surface of the inclined surface. An ice scraper 7 is coaxially installed in the ice bucket 4. The ice scraping surface of the ice scraper 7 is close to the inner wall of the ice bucket 4. The ice scraper 7 is coaxially fixed with a rotating shaft 8. The ice scraper 7 scrapes the ice produced on the inner wall of the ice bucket 4. The inner wall of the ice bucket 4 is a cooled surface. When the water flow is cooled and condensed on the inner wall of the ice bucket 4, a layer of frost will be formed. The function of the ice scraper 7 is to scrape off this layer of frost. The ice scraper 7 is close to the inner wall of the ice bucket 4. Through close contact with the inner wall, the frost can be effectively scraped off. The scraped frost will fall smoothly into the bottom of the ice bucket 4 with the movement of the ice scraper 7. An ice-pushing plate 9 is fixedly arranged at the bottom of the rotating shaft 8, an ice outlet 10 is provided at the bottom of the ice bucket 4, and an ice-pressing bin 11 is fixedly arranged at the position of the ice outlet 10. The ice-pushing plate 9 will push the frost formed in the ice bucket 4 from the ice outlet 10 to the ice-pressing bin 11, providing a frost source for the ice-pressing plate 12. Through the action of the ice-pushing plate 9, it can be ensured that there is always enough frost in the ice-pressing bin 11 for squeezing, thereby improving the efficiency of making ice cubes. An ice-pressing plate 12 for squeezing ice into ice cubes is arranged in the ice-pressing bin 11, a push rod 16 is arranged at the top of the ice-pressing plate 12, and a piston module 13 for pushing the push rod 16 to slide is arranged on the right side of the push rod 16. When the frost generated on the inner wall of the ice bucket 4 is scraped by the ice-scraping plate 7 to the ice outlet 10 at the bottom of the ice bucket 4, the role of the ice-pressing bin 11 is to squeeze the frost into ice cubes. The ice-pressing plate 12 squeezes the frost to form solid square ice cubes. The ice pressing bin 11 can accommodate and store the ice cubes formed by squeezing. In this way, the ice bucket 4 can continue to make new frost without worrying that the previously made ice cubes will affect the ice making efficiency. And because the frost is discharged from the ice bucket 4, water is attached to its surface, and when the frost pile is pressed into a cube shape, due to its low temperature, the water attached to its surface will condense into ice, and the air temperature around the ice cube is lower than the surface temperature of the ice cube, resulting in the water molecules in the water on the ice surface contacting the lower temperature air will become slower and condense into ice crystals. When the water on the ice surface condenses into ice, the ice crystals between the frost and the frost will adhere to each other to form a loose ice cube structure. Since frost forms some tiny gaps when it condenses, when the frost contacts each other, these tiny gaps will connect with each other, so that there are some gaps and intervals between the ice, forming a loose structure. This loose ice cube structure makes the ice cube looser and easier to break. When the ice cube is placed in the liquid, the liquid will enter the ice cube through the gaps and contact with more of the ice cube surface, and heat is often transferred from the liquid to the ice cube by conduction. Since the loose structure increases the contact area between the ice cube and the liquid, the efficiency of heat transfer will also increase accordingly.Therefore, the ice cubes with loose structure can melt faster. In the manufacture of soft ice, the loose structure can make the ice cubes softer and easier to scrape, and also increase the taste of the ice cubes and their melting speed and cooling speed. In the preparation of beverages, the soft ice cubes can be more quickly dissolved in the beverage, so that the beverage can be cooled more evenly and quickly. At the same time, the soft ice cubes will not produce too much noise and debris when stirred or poured, and are more suitable for making beverages that require a delicate taste, such as coffee and milkshakes. Moreover, the soft ice cubes are more easily stirred by a stirrer or a straw, which is convenient for the preparation and drinking of beverages. And in medical and emergency situations, soft ice cubes and easy-to-scrape ice cubes can be used for cold compresses or wound treatment. Soft ice cubes can better adapt to body curves and shapes, providing a more comfortable cold compress effect. And easy-to-scrape ice cubes can more easily contact with wounds, playing a role in hemostasis and analgesia.

[0034] See also Figure 5 and Fig.10A heat pipe 14 is embedded in the inner wall of the ice pressing bin 11, and the heat pipe 14 is connected to the heat pipe of the compressor 3. A heat pipe 2 15 is arranged in the ice pressing plate 12, and the heat pipe 2 15 is connected to the heat pipe of the compressor 3. After the ice cubes are pressed and formed, the heat pipe of the compressor 3 transports high-temperature coolant to the heat pipe 14 and the heat pipe 2 15, so that the surface temperature of the ice pressing bin 11 and the ice pressing plate 12 increases, and the surface of the ice cubes in contact with the ice pressing bin 11 and the ice pressing plate 12 melts, and a lubricating film is formed between the ice cubes and the ice pressing bin 11 and the ice pressing plate 12, thereby reducing the friction between the ice cubes and the container. After the ice cubes are formed, they can be easily separated from the ice pressing bin 11, so as to achieve the purpose of separating the ice cubes from the ice pressing bin 11. An inclined surface is arranged at the connection between the ice pressing bin 11 and the ice outlet 10, and the inclined surface can smoothly guide the frost blocks sliding out of the ice pressing bin 11 into the ice pressing bin 11. By properly designing the angle and shape of the inclined plane, the frost block can be kept stable during the sliding process. Due to the inclination of the inclined plane, the frost block will be affected by gravity during the sliding process, so that it can slide to the position of the ice outlet 10 faster. Compared with a flat connection, the inclined plane can reduce the friction between the frost and the inner wall of the ice pressing bin 11, so that the ice cubes can slide out more easily. A height sensor 26 for monitoring the amount of ice in the ice pressing bin 11 is provided at the bottom of the inclined plane. The role of the height sensor 26 in the above structure is to monitor the amount of ice in the ice pressing bin 11. By measuring the height of the ice, the accumulation of ice in the ice pressing bin 11 can be understood, thereby controlling the generation and separation process of ice. A proximity sensor or an ultrasonic sensor can be used to measure the height of ice in the ice pressing bin 11. Proximity sensors are generally more suitable for measuring shorter distances, while ultrasonic sensors can measure longer distances. According to the size of the ice pressing bin 11 and the range of ice height variation, a suitable sensor type can be selected to achieve height measurement. A door 24 is provided at the bottom of the ice compressing bin 11 and is rotated by electric control. The doors 24 are symmetrically arranged on both sides of the bottom of the ice compressing bin 11. The size of the doors 24 is larger than the size of the ice cubes compressed by the ice pressing plate 12. When the door 24 is rotated to a vertical direction, the ice cubes compressed above the door 24 fall down, and the ice pushing plate 9 pushes the ice toward the ice outlet 10. An ice box 25 for storing ice cubes is provided at the bottom of the door 24.

[0035] See also Fig. 9, the rotating shaft 8 passes through the bottom end surface of the ice bucket 4, and a driving motor 17 is arranged at the bottom end of the rotating shaft 8 to drive the rotating shaft 8 to rotate. The driving motor 17 is connected to the rotating shaft 8 through a transmission belt 18, and a fixing plate 19 is arranged on the top of the driving motor 17, and the fixing plate 19 is fixed on the housing 1. By controlling the different rotation speeds of the driving motor 17, different forms of ice can be generated in the ice bucket 4. When the motor rotates at a high speed, the ice scraper 7 rotates at a high speed at this time, and the time for water to adhere to the surface of the ice bucket 4 becomes shorter. The water will be quickly taken away at the moment of contact with the ice scraper 7, and cannot be completely attached to the surface of the ice bucket 4 to form a uniform ice layer. Therefore, only a thin frost layer can be formed. In addition, the high-speed rotating ice scraper 7 can also effectively disperse and scatter the water in the ice bucket 4, reducing the possibility of water accumulation on the surface of the ice bucket 4. In this way, even if some water adheres to the surface of the ice bucket 4 to form frost, it will be quickly taken away by the ice scraper 7 and will not accumulate to form a thick ice layer. Thus, ice in a frost state is produced in the ice bucket 4; when the speed of the driving motor 17 is reduced, the speed of the ice scraper 7 is slower, and the time for water to adhere to the surface of the ice bucket 4 becomes longer. Since the ice scraper 7 rotates at a slower speed, the water will have more time to adhere to the surface of the ice bucket 4 to form ice flakes at the moment of contact with the ice scraper 7. In this way, the water can be more fully frozen on the surface of the ice bucket 4 to form a uniform ice layer. Then, the ice flakes formed are scraped off by the ice scraper 7. Since the ice flakes formed when rotating at a low speed have a certain curvature, the ice scraper 7 can scrape these ice flakes off the surface of the ice bucket 4. In this way, normal ice flakes are formed in the ice bucket 4 instead of frost. Finally, the ice flakes are pressed into square ice by the ice pressing bin 11. Since the ice flakes formed when rotating at a low speed have a certain curvature, these ice flakes will be flattened and formed into square ice cubes under the action of the ice pressing bin 11. Since the surface of the square ice cube is curved, the gap of its inner wall is larger. When placed in liquid, the contact area between this square ice cube and the liquid is larger than that of ordinary square ice cubes, thereby improving the heat exchange efficiency.

[0036] See also Figure 5, the annular diameter of the water outlet 5 is smaller than the top diameter of the ice bucket 4, and the annular diameter of the water outlet 5 is smaller than the top diameter of the ice bucket 4, which can ensure that water can flow smoothly from the bottom of the ice bucket 4 to the water outlet 5 during the ice making process. This design can ensure that the water in the ice bucket 4 can be fully circulated during the ice forming process, thereby accelerating the cooling speed and ice formation. The top diameter of the ice bucket 4 is larger than the bottom diameter, and the refrigeration pipe 6 is arranged in a spiral shape along the outer wall of the ice bucket 4. The cross-sectional shape of the refrigeration pipe 6 is set to be circular or square. The cross-sectional shape of the refrigeration pipe 6 is set to be circular or square mainly to optimize the refrigeration effect and the structural design of the ice bucket 4. First, both the circular and square cross-sectional shapes can provide a large surface area for heat exchange. Since the process of ice making requires the refrigeration pipe 6 to transfer the heat of the cooling medium, the cross-sectional shape of the refrigeration pipe 6 must be able to fully contact the water in the ice bucket 4 to achieve effective heat exchange. The circular and square cross-sectional shapes can maximize the surface area of ​​the refrigeration pipe 6, improve the heat conduction efficiency, and accelerate the cooling speed. Secondly, the circular and square cross-sectional shapes are also conducive to the structural design of the ice bucket 4 and the arrangement of the refrigeration pipe 6. The circular cross-sectional shape is relatively uniform, and the arrangement of the refrigeration pipe 6 in the ice bucket 4 is more uniform and compact. The square cross-sectional shape can better adapt to the structure of the ice bucket 4, so that the water in the ice bucket 4 flows more smoothly, avoiding dead corners and problems of poor water flow. An annular reflux groove 20 is also provided at the bottom of the ice bucket 4. The function of the reflux groove 20 is mainly to reduce the water contained in the ice and the water that is not frozen during the ice making process. A filter 21 is provided between the reflux groove 20 and the ice bucket 4. The filter 21 can ensure that only water will flow into the reflux groove 20, and the generated ice will be discharged from the ice outlet 10. The bottom of the reflux groove 20 is connected to a reflux pipe 22 that returns the water stored therein to the water storage tank 2. A water pump module 23 is provided on the reflux pipe 22. The water collected in the reflux groove 20 can be pumped back to the water storage tank 2 through the reflux pipe 22 for reuse, which can save water resources and reduce waste.

[0037] Working principle: When the device is in use, the compressor 3 is started to pass the refrigerant into the refrigeration pipe 6 to reduce the temperature of the inner wall of the ice bucket 4. When the surface temperature of the ice bucket 4 reaches about -6°C to -8°C or 20°F to 18°F, the water outlet 5 at the bottom of the water storage tank 2 is started to drain water to the inner wall of the ice bucket 4, and the drive motor 17 is started synchronously to drive the rotating shaft 8 and the ice scraper 7 installed on its shaft; when water passes through the inner wall of the ice bucket 4, it will quickly condense frost and be immediately scraped to the bottom of the ice bucket 4 by the ice scraper 7, and then pushed from the ice outlet 10 to the ice pressing bin 11 through the ice pushing plate 9 coaxially connected to the rotating shaft 8. When the height sensor 26 in the ice pressing bin 11 detects that the frost in the ice pressing bin 11 has reached a certain height, the device will start the piston module 13 to push the push rod 16 to drive the ice pressing plate 12 to move along the ice pressing bin 11 to its left side, such as Fig.10 and Fig.11As shown, the frost pile collected in the ice pressing bin 11 is pressed into ice cubes; while in the process of forming ice cubes on the left side of the ice pressing bin 11, the ice outlet 10 will not be affected by this movement, and will also transport frost into the ice pressing bin 11 to form a frost pile. When the ice cubes on the left side are completely formed, the bin door 24 at the bottom of the ice pressing bin 11 rotates to make the ice cubes fall into the ice box 25. The bin door 24 opens and the ice falling process is as shown in FIG. Fig.12 As shown in the dotted line portion, a new frost pile is formed on the right side of the ice pressing plate 12, and then the piston module 13 pulls the push rod 16 and the ice pressing plate 12 to move to the left to move the frost pile collected in the ice pressing bin 11 to the right and press it into blocks, and then the bin door 24 at the bottom of the ice pressing bin 11 rotates to make the ice cubes fall into the ice box 25, as shown in FIG. Fig.13 As shown, this back-and-forth motion design allows the frost to be continuously pressed into ice cubes without idle time for ice making, thereby improving the ice making efficiency of the device. Since the frost is discharged from the ice making bucket 4, water is attached to its surface, and when the frost pile is pressed into a cube shape, due to its low temperature, the water attached to its surface will condense into ice, and the air temperature around the ice cube is lower than the surface temperature of the ice cube, resulting in the water molecules in the water on the ice surface contacting the lower temperature air more slowly and condensing into ice crystals. When the water on the ice surface condenses into ice, the ice crystals between the frost and the frost will adhere to each other to form a loose ice cube structure. Since frost forms some tiny gaps when condensing, when the frost contacts each other, these tiny gaps will be connected to each other, so that there are some gaps and intervals between the ice, forming a loose structure. This loose ice cube structure makes the ice cube looser and easier to break. When the ice cube is placed in a liquid, the liquid will enter the ice cube through the gaps and contact more of the ice cube surface, and heat is often transferred from the liquid to the ice cube by conduction. Since the loose structure increases the contact area between the ice cube and the liquid, the efficiency of heat transfer will also increase accordingly. Therefore, the ice cube with a loose structure can melt faster. In the manufacture of this soft ice, this loose structure can make the ice cube softer and easier to scrape, and also increase the taste of the ice cube and its melting speed and cooling speed. In the preparation of beverages, the soft ice cube can be more quickly dissolved in the beverage, so that the beverage can be cooled more evenly and quickly. At the same time, the soft ice cube will not produce too much noise and debris when stirring or pouring, and is more suitable for making beverages that require a delicate taste, such as coffee and milkshakes. Moreover, soft ice cubes are easier to stir with a blender or straw, making beverage preparation and drinking easier. And in medical and emergency situations, soft ice cubes and easy-to-scrape ice cubes can be used for cold compresses or wound treatment. Soft ice cubes can better adapt to body curves and shapes, providing a more comfortable cold compress effect. And easy-to-scrape ice cubes can more easily contact wounds, playing a role in hemostasis and analgesia.

[0038] The device can also form traditional ice cubes on the surface of the ice bucket 4 by controlling the rotation speed of the driving motor 17. When the rotation speed of the driving motor 17 is reduced, the ice scraper 7 rotates slowly at this time, so that the water adheres to the surface of the ice bucket 4 for a longer time, forming normal ice flakes, and then the ice flakes are scraped off by the ice scraper 7. Moreover, since the ice flakes formed in the round barrel itself have a certain curvature, when the curved ice is pressed into the form of ice cubes by the ice pressing bin 11, its curved surface makes the gap of its inner wall larger. When placed in a liquid, its contact area with the liquid is larger than that of ordinary ice cubes, and the heat exchange efficiency is higher. However, this ice cube is harder than ice formed by frost. In tropical climates and outdoor activities, the density of this harder ice cube is lower than that of ordinary ice cubes, which is convenient for outdoor camping and carrying.

[0039] After the ice cubes are pressed and formed, the heat dissipation pipe of the compressor 3 transports high-temperature coolant to the heat pipe 1 14 and the heat pipe 2 15, so that the surface temperature of the ice pressing bin 11 and the ice pressing plate 12 increases, and the contact surface of the ice cubes with the ice pressing bin 11 and the ice pressing plate 12 melts, and a lubricating film is formed between the ice cubes, the ice pressing bin 11 and the ice pressing plate 12, thereby reducing the friction between the ice cubes and the container. After the ice cubes are formed, they can be easily separated from the ice pressing bin 11, thereby achieving the purpose of separating the ice cubes from the ice pressing bin 11.
