Description

Technical Field

[0001] The invention relates to the technical field of energy-saving ice making, and in particular to an embedded ice making machine. Background Art

[0002] The existing ice maker is an electrical device specially used for making ice cubes. It is designed to be embedded in a cabinet, kitchen, cabinet and bar counter, and integrated with the surrounding environment. While saving space, it can also provide users with a convenient ice-making function.

[0003] In a Chinese patent with patent publication number CN207778903U, a refrigerator is disclosed, comprising: a refrigerating chamber, a refrigerating chamber door body, an ice maker cold supply box, an air inlet duct and a return air duct, the outer wall of the refrigerating chamber is covered with a shell, the rear wall of the shell is formed with an opening, a recessed portion recessed inwardly is formed at a position opposite to the opening on the outer side of the rear wall of the refrigerating chamber, the ice maker cold supply box is arranged in the recess through the opening, an ice evaporator and a fan for blowing a cold air flow around the ice evaporator are arranged in the ice maker cold supply box, an ice making chamber is formed on the inner side of the refrigerating chamber door body, an ice maker is arranged in the ice making chamber, an air inlet duct is configured to receive the cold air flow blown by the fan and guide it to the ice maker, and a return air duct is configured to guide the air flow after heat exchange with the ice maker to the area where the ice evaporator is located, so that the air flow after heat exchange with the ice maker is cooled by the ice evaporator and then guided to the ice maker through the air inlet duct.

[0004] However, the prior art still has the following defects when used specifically: 1. Compared with the equipment involved in the prior art, a recess is formed at the position opposite to the opening on the outer side of the rear wall of the refrigerating chamber, the ice-making machine cold supply box is arranged in the recess through the opening, and the ice-making evaporator is located in the ice-making machine cold supply box to avoid the influence of the cold air flow around the ice-making evaporator on the interior of the refrigerating chamber. Furthermore, by setting an independent ice-making evaporator, more cooling capacity is provided for the ice-making machine, and the ice-making efficiency of the ice-making machine is improved. However, when the ice-making evaporator is located in a relatively closed recess, air convection will be greatly restricted. Under normal circumstances, when the evaporator releases heat, the surrounding air will absorb the heat and take away the heat through natural convection or the assistance of a fan. However, in the recess, the air flow space is narrow and it is difficult to form effective convection. This reduction in heat dissipation efficiency will cause the ice-making evaporator to take a longer time to complete heat release during the defrosting process. Because the heat cannot be dissipated in time, the temperature around the ice-making evaporator will continue to rise, making the defrosting process slow, thereby affecting the entire working cycle of the ice-making machine.

[0005] 2. Compared with the prior art, after the ice maker is horizontally embedded in the cabinet and installed, since the side walls of the ice maker are tightly fitted to the cabinet, it is difficult for air to flow around the side walls, thereby limiting the heat dissipation capacity of the side walls. Therefore, the heat dissipation and ventilation can only rely on the bottom and the rear side walls. However, since the side walls cannot effectively dissipate heat, the heat dissipation area of ​​the ice maker is reduced. According to the principle of heat conduction, the smaller the heat dissipation area, the slower the heat dissipation rate under the same heat dissipation conditions, such as the same ambient temperature and air flow rate, which will cause heat accumulation inside the ice maker, so that the refrigeration system needs to spend more energy to maintain a low temperature environment for ice making. In addition, in order to maintain a normal ice-making temperature inside the ice maker, the refrigeration system needs to continue to work at a high intensity, which leads to an increase in energy consumption. Compared with ice makers used in other scenarios, this embedded ice maker consumes 20% to 50% more electricity. Long-term use will increase the user's electricity cost.

[0006] In view of this, the present invention proposes an embedded ice maker to make up for and improve the deficiencies of the prior art. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides an embedded ice maker to solve the technical problems raised in the above background technology.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is: an embedded ice maker, comprising an ice making machine body, a refrigeration module is installed inside the ice making machine body, and a heat-cold circulation mechanism is provided on the inner wall of the ice making machine body. The heat-cold circulation mechanism is used to absorb the hot air and cold air generated when the refrigeration module is in operation, and to recycle and utilize them subsequently.

[0009] Furthermore, the heat and cold cycle mechanism includes a central axis cylinder rotatably connected to the inner wall of the refrigerator body, the interior of the central axis cylinder is symmetrically installed with a threaded shaft, the outer walls of the threaded shaft are symmetrically installed with nut rings, and the two sides of the central axis cylinder are symmetrically connected with collection bins.

[0010] Furthermore, the interior of the central axis tube is symmetrically divided into two upper and lower areas, and the outer wall of the central axis tube is symmetrically provided with discharge openings.

[0011] Furthermore, adsorption plates are symmetrically installed on the inner side walls of the collection bin, adsorption ports are evenly opened on the surface of the adsorption plates, and the adsorption plates are made of activated carbon material as a whole.

[0012] Furthermore, the central shaft tube is rotatably connected to the threaded shaft, and the ends of the threaded shaft are externally connected to micro motors.

[0013] Furthermore, the threaded shaft is threadedly connected to the nut collar, a ball screw structure is formed between the threaded shaft and the nut collar, and the nut collar is initially located at the center of the outer wall of the threaded shaft.

[0014] Furthermore, the central axis tube and the collecting bin are connected via a discharge port, the collecting bin is trapezoidal in shape as a whole, and the collecting bin is narrow at one end close to the central axis tube and wide at one end away from the central axis tube.

[0015] Furthermore, a water supply module is installed inside the refrigerator body, and a water-cooling heat dissipation mechanism is symmetrically arranged outside the water supply module. The water-cooling heat dissipation mechanism is used to circulate the water flow in the water supply module to guide the heat dissipation of the side wall of the refrigerator body. The water-cooling heat dissipation mechanism includes connecting pipes symmetrically connected to the outside of the water supply module, the outside of the connecting pipes are connected to branch pipes, and the outside of the branch pipes are installed with fin groups.

[0016] Furthermore, the outer wall of the fin group is composed of no less than three arc-shaped fins, and the interiors of the arc-shaped fins are all hollow.

[0017] Furthermore, the outside of the connecting pipe is connected to no less than four branch pipes, and no less than three inclined columns are arranged outside the branch pipes. The branch pipes are slidably connected to the fin group through the inclined columns and the arc-shaped fins.

[0018] Furthermore, the water delivery module mainly includes a water delivery pipeline, a water pump and a recovery bin, the input end of the connecting pipe is connected to the water delivery pipeline in the water delivery module, and the output end of the connecting pipe is connected to the recovery bin in the water delivery module.

[0019] Furthermore, an ice-making module is installed inside the refrigerator body, and the ice-making module mainly includes an ice-making evaporator and an ice-making mold, and the ice-making mold fits tightly above the ice-making evaporator. The refrigeration module mainly includes a compressor, a condenser and an expansion valve, and the refrigeration module is connected to the ice-making evaporator in the ice-making module.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In order to improve the ice-making efficiency and ice-removing rate in the prior art, the present device introduces a hot-cold circulation mechanism, so that suction is formed inside the central axis tube during the ice-making process, and then continuously absorbs hot air and cold air from the vicinity of the condenser and the ice-making evaporator respectively, thereby maintaining a stable working temperature environment of the ice-making evaporator and the condenser, so that the ice-making evaporator can absorb heat and cool more efficiently, thereby accelerating the ice-making speed. From the perspective of heat transfer, this method reduces the mixing of hot and cold gases around the evaporator and the condenser, and increases the temperature difference between the evaporator and the refrigerated object by promptly absorbing the hot air around the evaporator and the cold air around the condenser, thereby accelerating the heat transfer speed and improving the ice-making efficiency.

[0021] Secondly, when the equipment is in the defrosting state, the collecting bin rotates, and the reset movement of the threaded shaft generates thrust inside the central axis tube. At this time, the heat collected from the condenser during the ice-making process is discharged in the direction of the ice-making evaporator, creating a preheating environment for the ice-making module to defrost. This is equivalent to providing an additional heat source for the evaporator, accelerating the melting rate of ice on the surface of the ice-making module. At the same time, the cold air collected in the ice-making evaporator in advance is position-changed and discharged in the corresponding condenser, creating a cooling environment for the condenser, which helps to maintain the normal working state of the condenser during the defrosting process. According to the law of conservation of energy, during the defrosting process, part of the heat released by the evaporator is used to melt the ice, and part needs to be dissipated to the surrounding environment. The device can ensure that the condenser part remains at a low temperature, which is beneficial to the dissipation of heat from the evaporator, thereby accelerating the defrosting process.

[0022] Compared with the ice-making method in the prior art, the device has improved ice-making efficiency and can produce more ice cubes per unit time, meeting the user's demand for a large amount of ice cubes in a short time. At the same time, it speeds up the defrosting rate, which can shorten the entire ice-making cycle, improve the working efficiency of the ice-making machine, ensure that the user can get the next batch of ice cubes faster, and improve the user experience.

[0023] Moreover, through the exhaust method of the device, the natural discharge of gas from the inside of the device to the outside is realized. Compared with the prior art using fans, the device eliminates the problem of noise generated by the fans. For the use scenarios of the equipment, reducing noise can improve the comfort of life and ensure that the ice maker will not cause noise pollution to the home environment during operation. For commercial places, noise reduction can also improve customer satisfaction and provide customers with a quieter environment.

[0024] Among them, in the entire ice-making and ice-defrosting cycle, the device realizes the recovery and reuse of heat and cold, so that the hot and cold gases collected in the ice-making process are redirected and distributed in the ice-defrosting process, reducing the need for additional energy input. Optimizing energy utilization helps to reduce the energy consumption of the ice-making machine, which meets the requirements of modern energy conservation and environmental protection, and can significantly reduce operating costs for places where ice-making machines are used on a large scale, such as large catering companies, hotels, etc.

[0025] Among them, the directional absorption of hot and cold gases, as well as the directional discharge of hot and cold gases, both help to maintain the temperature of various components inside the equipment stable. A stable thermal environment helps to extend the service life of various components inside the ice maker and reduce component damage and failures caused by temperature fluctuations. This can not only reduce the maintenance cost of the ice maker, but also improve the reliability and stability of the equipment. This advantage is even more obvious for ice makers that run continuously for a long time.

[0026] Among them, the device introduces an adsorption plate on the inner wall of the collecting bin, which can ensure that the gas absorbed from the condenser and the evaporator is in full contact with the adsorption plate during the flow process, thereby effectively filtering out tiny particles such as dust and impurities in the gas to prevent them from entering other key internal components of the ice maker. In addition, through the adsorption effect of the adsorption plate, it can also ensure that the produced ice cubes have no odor, so that when used for beverages and other foods, it will not destroy the original taste of the beverage and improve the overall quality of the food.

[0027] In order to improve the problem of heat dissipation of the side wall of the embedded device, the device introduces a fin group, so that the surface contact between the side wall of the device and the cabinet is changed to multiple point contacts, which effectively increases the heat dissipation area of ​​the side wall of the ice maker. According to the principle of heat conduction, the larger the heat dissipation area, the faster the heat dissipation rate under the same heat dissipation conditions, and the length of the fin group itself ensures the heat dissipation space between the cabinet and the side wall of the ice maker, so that air can flow between the fin groups, further enhancing the heat dissipation effect, reducing heat accumulation inside the ice maker, and reducing the energy required for the refrigeration system to maintain a low-temperature environment. In addition, the introduction of the fin group also provides better protection when the ice maker is horizontally embedded in the cabinet. The fin group can prevent excessive friction between the side wall of the ice maker and the cabinet, reducing damage and wear caused by friction.

[0028] Compared with the existing technology, the water-cooling heat dissipation structure introduced in this device based on the principle of heat conduction makes it easier to maintain the internal temperature of the equipment in a suitable ice-making temperature range, and does not require over-cooling of the refrigeration system. This greatly reduces the power consumption of the ice maker under the same ice-making task. Compared with previous embedded ice makers, it can effectively reduce power consumption and greatly reduce users' electricity costs.

[0029] What is particularly important is that the interior of the fin is designed to be hollow and connected to the branch pipe, so that the water flow transported by the water delivery module can flow inside the branch pipe, forming a heat conduction group inside the fin. Since water has a large latent heat of vaporization, in the heat pipe structure formed, when one end of the heat pipe contacts the high-temperature area inside the side wall of the ice maker, the water absorbs heat and quickly evaporates into water vapor. Due to the flow characteristics of water vapor, it will move to the cooling end of the heat pipe. At the cooling end, the water vapor condenses into liquid water when it is cooled, releasing heat, which is then dissipated to the external environment through the fin group. This water-based heat pipe heat dissipation mechanism effectively conducts the heat inside the side wall of the ice maker and dissipates it to the outside, further enhancing the heat dissipation capacity of the side wall of the ice maker.

[0030] The above-mentioned introduction of water flow and recycling through the water delivery module also has the following benefits: First, by introducing water flow into the branch pipe and using the water delivery module to achieve continuous water injection, it can be ensured that there is always fresh water flow in the heat pipe structure formed inside the fin group for heat dissipation, which helps to maintain the heat dissipation effect of the water medium and prevent the heat dissipation efficiency from being reduced due to overheating of the water flow.

[0031] Second: The output end of the connecting pipe is connected to the recovery bin in the water delivery module, which means that the water used in the ice-making process can be recycled and reused. This recycling design not only saves water resources, but also reduces wastewater discharge, which meets the requirements of environmental protection and sustainable development.

[0032] Third: Continuous water injection and circulation help to maintain the temperature and flow of water in the heat pipe stable, thereby improving the heat transfer efficiency, which means that under the same heat dissipation conditions, the heat generated inside the ice maker can be dissipated more quickly by using recycled water, reducing the energy consumption of the refrigeration system. In addition, through continuous water injection and circulation, impurities and sediments in the water in the heat pipe can be reduced, keeping the heat pipe clean and unobstructed, and reducing failures and maintenance costs caused by blockage or corrosion of the introduced structure.

[0033] Fourthly, the introduced structure is combined with the water delivery module in the existing equipment, and the water delivery module is used to realize the injection and recovery of water flow, which can simplify the design of the structure and the subsequent maintenance process.

DETAILED DESCRIPTION

[0046] 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.

[0047] It should be noted that the structures and working principles of the above-mentioned refrigerator body 1, water delivery module 11, ice making module 12, refrigeration module 13 and other components belong to the prior art and will not be described in detail here.

[0048] Example 1: Please refer to Figures 1 to 3 As shown, an embedded ice maker includes an ice making machine body 1, a refrigeration module 13 is installed inside the ice making machine body 1, and a heat-cold circulation mechanism 2 is provided on the inner wall of the ice making machine body 1. The heat-cold circulation mechanism 2 is used to absorb the hot air and cold air generated when the refrigeration module 13 is in operation, and to recycle and utilize them subsequently.

[0049] It should be noted that the water supply module 11 mainly includes a water supply pipeline, a water pump and a recovery bin. The input end of the connecting pipe 31 is connected to the water supply pipeline in the water supply module 11, and the output end of the connecting pipe 31 is connected to the recovery bin in the water supply module 11. An ice-making module 12 is installed inside the refrigerator body 1. The ice-making module 12 mainly includes an ice-making evaporator and an ice-making mold, and the ice-making mold is tightly fitted above the ice-making evaporator. The refrigeration module 13 mainly includes a compressor, a condenser and an expansion valve. The refrigeration module 13 is connected to the ice-making evaporator in the ice-making module 12.

[0050] Specifically, in the ice-making process, first, the compressor in the refrigeration module 13 compresses the refrigerant into a high-pressure gas, raising its temperature and pressure, and then the high-temperature and high-pressure refrigerant gas releases heat in the condenser and turns into a high-pressure liquid. When the high-pressure liquid passes through the expansion valve, the high-pressure liquid refrigerant is depressurized and partially turned into a low-temperature and low-pressure gas-liquid two-phase object. When it reaches the ice-making evaporator in the ice-making module 12, the refrigerant absorbs heat from the surrounding environment and turns into a low-temperature and low-pressure gas again, thereby achieving refrigeration and ice-making. In the ice-making process, since the heat is released around the condenser, the temperature around the condenser is relatively high. , and the ice-making evaporator absorbs the surrounding heat to cool down the ice-making module installed on the side wall and condense ice. Later, when defrosting is performed after ice making is completed, the ice-making evaporator changes its working state. Specifically, during the ice-making process, the ice-making evaporator is a component that absorbs heat to freeze water, and during the defrosting process, the working mode of the ice-making evaporator changes. At this time, the ice-making evaporator begins to release heat. This is because after ice making is completed, the ice cubes are attached to the ice-making module, and the ice-making module needs to be heated to make the ice cubes fall off. At this time, the ice-making evaporator releases heat to increase the temperature of the ice-making module, thereby achieving defrosting.

[0051] Please refer to Figures 3 to 8 As shown, the hot and cold circulation mechanism 2 includes a central axis tube 21 rotatably connected to the inner wall of the refrigerator body 1, a threaded shaft 22 is symmetrically installed inside the central axis tube 21, and a nut ring 23 is symmetrically installed on the outer wall of the threaded shaft 22, and a collection bin 25 is symmetrically connected to both sides of the central axis tube 21.

[0052] It should be noted that the interior of the central axis tube 21 is symmetrically divided into two upper and lower areas, and the outer wall of the central axis tube 21 is symmetrically provided with discharge ports, the central axis tube 21 is rotatably connected to the threaded shaft 22, and a micro motor is externally connected to the end position of the threaded shaft 22, the threaded shaft 22 is threadedly connected to the nut ring 23, and a ball screw structure is formed between the threaded shaft 22 and the nut ring 23, and the nut ring 23 is initially located at the center position of the outer wall of the threaded shaft 22, the central axis tube 21 is connected to the collecting bin 25 through the discharge port, the collecting bin 25 is trapezoidal as a whole, and the collecting bin 25 is narrow at the end close to the central axis tube 21, and wide at the end away from the central axis tube 21.

[0053] Specifically, during the ice-making process, the micro-motor externally connected to the end of the threaded shaft 22 will control it to keep rotating. Since the structure between the threaded shaft 22 and the nut collar 23 is similar to that of a ball screw, and the pitch of the outer wall of the threaded shaft 22 is equal to the inner diameter of the nut collar 23, and the angle between the tangent of the outer wall thread of the threaded shaft 22 and the cylinder and the horizontal plane is greater than 45 degrees, when the threaded shaft 22 keeps rotating, its own rotational force will continue to squeeze the nut collar 23 through the thread of the outer wall, and then smoothly transfer the rotational force to the nut collar 23, driving it to move linearly inside the central shaft tube 21. In the process of the nut collar 23 moving from the middle position of the central shaft tube 21 to the end position, the space inside the central shaft tube 21 gradually increases, and at this time, the space inside the central shaft tube 21 The air pressure inside the central axis tube 21 is lower than the air pressure outside the central axis tube 21, thereby generating suction inside the central axis tube 21, and this suction will act on the ice-making evaporator and condenser parts respectively through the collecting bins 25 at the upper and lower ends, thereby absorbing the gas generated by the two parts when working into the collecting bins 25, thereby maintaining the stable working temperature environment of the ice-making evaporator and the condenser respectively, so that the ice-making evaporator can absorb heat and cool more efficiently, thereby accelerating the ice-making speed. From the perspective of heat transfer, this method reduces the mixing of hot and cold gases around the ice-making evaporator and the condenser, and increases the temperature difference between the ice-making evaporator and the refrigerated object by promptly absorbing the hot air around the ice-making evaporator and the cold air around the condenser, thereby accelerating the heat transfer speed and improving the ice-making efficiency.

[0054] Moreover, during the de-icing process, the collecting bin 25 is driven by an external controller to rotate as a whole, so that the collecting bin 25 initially corresponding to the ice-making evaporator is converted to the corresponding condenser, and the collecting bin 25 initially corresponding to the condenser is converted to the corresponding ice-making evaporator. At this time, with the continuous rotation of the threaded shaft 22, the nut collar 23 begins to reset, that is, it moves from the end position inside the central shaft tube 21 to the center position. During this process, the space inside the central shaft tube 21 gradually becomes smaller, and at this time, the air pressure inside the central shaft tube 21 is greater than the air pressure outside the central shaft tube 21, thereby generating a push inside the central shaft tube 21. The force, along with the formation of thrust, will be transmitted to the inside of the collecting bin 25, and then the gas collected in the ice-making process will be discharged. At this time, the heat collected from the condenser during the ice-making process will be discharged in the direction of the ice-making evaporator to create a preheating environment for the ice-making module to defrost. This is equivalent to providing an additional heat source for the evaporator, accelerating the melting rate of ice on the surface of the ice-making module on the side wall of the ice-making evaporator. At the same time, the cold air collected in the ice-making evaporator in advance will be converted and discharged in the corresponding condenser to create a cooling environment for the condenser, which helps to maintain the normal working state of the condenser during the defrosting process.

[0055] It should be noted that the inner side walls of the collecting bin 25 are symmetrically mounted with adsorption plates 24 , adsorption ports are evenly opened on the surface of the adsorption plates 24 , and the adsorption plates 24 are entirely made of activated carbon material.

[0056] Specifically, when the gas enters the collecting bin 25, it can ensure that the gas absorbed from the condenser and the ice-making evaporator contacts with the adsorption plate 24 during the flow process, thereby effectively filtering out tiny particles such as dust and impurities in the gas and preventing them from entering other key components inside the equipment. In addition, through the adsorption effect of the adsorption plate 24, it can also ensure that the produced ice cubes have no odor, so that when used for beverages and other foods, it will not destroy the original taste of the beverage, thereby improving the overall quality of the food.

[0057] Example 2: Based on Example 1, please refer to Figures 9 to 11 As shown, a water supply module 11 is installed inside the refrigerator body 1, and a water cooling heat dissipation mechanism 3 is symmetrically arranged outside the water supply module 11. The water cooling heat dissipation mechanism 3 is used to circulate the water flow in the water supply module 11 to guide the heat dissipation of the side wall of the refrigerator body 1. The water cooling heat dissipation mechanism 3 includes a connecting pipe 31 symmetrically connected to the outside of the water supply module 11, and the outside of the connecting pipe 31 is connected to a branch pipe 32, and the outside of the branch pipe 32 is installed with a fin group 33.

[0058] It should be noted that the outer wall of the fin group 33 is composed of no less than three arc-shaped fins, and the interior of the arc-shaped fins is hollowed out. The outside of the connecting pipe 31 is connected to no less than four branch pipes 32, and the outside of the branch pipes 32 is provided with no less than three inclined columns. The branch pipes 32 and the fin group 33 are slidably connected through the inclined columns and the arc-shaped fins.

[0059] Specifically, since the input end of the connecting pipe 31 is connected to the water supply pipeline in the water supply module 11, and the output end of the connecting pipe 31 is connected to the recovery bin in the water supply module 11, when the device needs to be filled with water to make ice, part of the water will flow through the connecting pipe 31 and fill the inside of the branch pipe 32. Since the inside of the fin is designed to be hollow and connected to the branch pipe 32, the water flow transported by the water supply module 11 can flow inside the branch pipe 32, forming a heat conduction group inside the fin. Since water has a large latent heat of vaporization, in the formed heat pipe structure, when one end of the heat pipe contacts the high-temperature area inside the side wall of the device, the water absorbs heat and evaporates rapidly into water vapor. Due to the flow characteristics of water vapor, it moves to the cooling end of the heat pipe. At the cooling end, the water vapor is cooled and condensed into liquid water, releasing heat, which is then dissipated to the external environment through the fin group 33. This water-based heat pipe heat dissipation mechanism effectively conducts the heat inside the side wall of the device and dissipates it to the outside.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
