Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and particularly to an improvement in the structure of a refrigeration equipment with an ice maker. Background Art

[0002] Existing refrigeration equipment such as refrigerators and the like are equipped with ice makers to achieve the ice-making function. Ice makers are mainly classified into direct-cooling ice makers and air-cooling ice makers according to the refrigeration method.

[0003] The direct-cooling ice maker is provided with an ice-making evaporation pipe below the metal ice-making grid. When connecting to the refrigeration equipment, the ice-making evaporation pipe is connected to the refrigerant pipeline of the refrigeration system of the refrigeration equipment, generally in parallel connection with the evaporator. The ice-making evaporation pipe is in close contact with the ice grid on the ice maker, with a small heat transfer thermal resistance, and has the characteristics of high heat transfer efficiency and fast ice-making speed.

[0004] However, when installing the ice-making evaporation pipe, it needs to extend into the foaming layer of the refrigerator and connect to the refrigeration system located in the foaming layer of the refrigerator body, which makes it can only be installed inside the box body of the refrigeration equipment; The direct-cooling ice maker needs to be precisely assembled with the ice-making evaporation pipe. If the ice-making evaporation pipe extends too long or too short out of the box body, or the ice-making evaporation pipe itself is deformed, etc., it is very likely to cause the overall scrapping of the foaming box. The installation and assembly are cumbersome and inconvenient, and due to being assembled inside the box body, the maintainability is also poor.

[0005] To avoid installing the ice maker inside the box body, some refrigeration equipment is correspondingly equipped with air-cooling ice makers. It is a way of sending air through an air duct / air passage, and uses forced air flow to transfer cold with air as the working medium. Through the circulation of low-temperature air, the cold supply of the ice maker is completed. Therefore, air-cooling ice making is widely used in independent ice-making rooms, freezers, doors, etc. However, due to the large air flow resistance and large air supply temperature rise during air supply, the air-cooling ice-making speed is generally lower than that of direct-cooling ice making, with low ice-making efficiency, poor ice-making effect, and it is difficult to meet the user's rapid ice-making demand.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0007] In view of the above technical problems existing in the ice maker of the prior art refrigeration equipment pointed out in the background art, a new type of refrigeration equipment structure is proposed. Its ice maker can not only achieve direct-cooling rapid and efficient heat transfer, but also can be assembled on the door body, facilitating installation and maintenance operations.

[0008] To achieve the above invention purpose, the present invention adopts the following technical solutions to be realized: In some embodiments of the present application, a refrigeration device with an ice maker is provided, including: A box body; A door body, assembled on the box body, capable of rotating relative to the box body to open or close the box body; A refrigeration system, arranged in the box body, at least formed by connecting a compressor, a condenser, an evaporator, a throttling device, and an ice-making evaporator through a refrigerant pipeline; An ice maker, assembled on the door body, which includes: An ice-making grid, with a plurality of ice storage grids formed inside; A heat pipe component, one end of which exchanges heat with the water in the ice storage grid, and the other end is in contact and cooperation with the ice-making evaporator to exchange heat with the refrigeration system; When the door body is in the open state, the heat pipe component is separated from the ice-making evaporator; When the door body is in the closed state, the heat pipe component and the ice-making evaporator are in contact for heat exchange, so that the working medium located inside the heat pipe component flows and undergoes a phase change to refrigerate the water in the ice grid.

[0009] In some embodiments of the present application, a refrigeration device with an ice maker includes: A box body; A door body, assembled on the box body, capable of rotating relative to the box body to open or close the box body; A refrigeration system, arranged in the box body, at least formed by connecting a compressor, a condenser, an evaporator, and a throttling device through a refrigerant pipeline; An ice maker, assembled on the door body, which includes: An ice-making grid; A heat pipe component, one end of which exchanges heat with the water in the ice storage grid, and the other end exchanges heat with the refrigeration system; When the door body is in the open state, the heat pipe component is separated from the refrigeration system; When the door body is in the closed state, the heat pipe component exchanges heat with the refrigeration system, so that the working medium located inside the heat pipe component flows and undergoes a phase change to refrigerate the water in the ice grid.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are: In the refrigeration device of the present invention, the heat exchange component of the ice maker is replaced by a heat pipe component. By the contact and cooperation between the heat pipe component and the refrigeration system to transfer cold, it can be ensured that when the door body is opened, it is separated from the refrigeration system, and when the door body is closed, it is in contact with the refrigeration system for ice making. The assembly of the ice maker on the door body is realized without hindering the normal opening and closing of the door body. And when installing the heat pipe component, it only needs to be fixed to the ice-making grid, and the other end is in contact and cooperation with the ice-making evaporator of the refrigeration system, so the installation operation is more convenient and fast. And because it is assembled on the door body as a whole, the maintenance operation is also more convenient; Secondly, when the ice maker makes ice, after the heat pipe component contacts the refrigeration system, the working fluid inside undergoes a phase change and circulates to the heat pipe evaporation part to exchange heat with the ice making grid. The heat exchange method between the heat pipe component and the refrigeration system is a direct contact heat exchange structure, achieving the direct cooling contact heat exchange effect, ensuring the ice making speed and ice making effect of the ice making grid, and meeting the rapid ice making requirement.

Detailed Implementation Manner

[0015] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0016] The present invention provides a refrigeration device with an ice maker, including: A cabinet 110, including a cabinet shell, and the cabinet shell constitutes the external shell of the entire refrigeration device; An inner container component 220, arranged inside the cabinet shell, and a storage chamber is defined by the inner container component 220.

[0017] A foaming cavity is formed between the cabinet shell and the inner container component 220, and heat-insulating foam material is filled in the foaming cavity.

[0018] An opening is provided on the box body 110 to facilitate the user to take items from the refrigeration device.

[0019] The door body 210 is assembled at the opening of the box body 110 and can be rotated relative to the box body 110 to open or close the storage chamber; A refrigeration system is provided inside the box body 110, which is formed by connecting a compressor, a condenser, an evaporator, a solenoid valve and a throttling device through a refrigerant pipeline; The low-temperature and low-pressure refrigerant enters the compressor, and the compressor compresses it into a high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0020] The evaporator can refrigerate the items in the box body 110 by utilizing the latent heat of evaporation of the refrigerant.

[0021] In some embodiments of the present application, an ice maker is further provided on the refrigeration device.

[0022] The ice maker is assembled on the door body 210 and includes: An ice-making grid 400, inside which a plurality of ice storage grids are formed; The ice-making grid 400 is made of metal, and a partition member is provided inside it to divide the ice-making grid 400 into a plurality of ice storage grids for storing ice. The ice-making grid 400 is used to freeze the water stored inside it into ice cubes.

[0023] A baffle grille is arranged at the top of the ice-making grid 400 to block the ice cubes in the ice-making grid 400 to prevent them from falling.

[0024] To heat the ice cubes in the ice-making grid 400, a scraping and heating tube is further provided around the circumference of the bottom of the ice-making grid 400, which is arranged circumferentially around the ice-making grid 400.

[0025] To install the scraping and heating tube, a heating tube installation groove 450 is provided around the circumference of the ice-making grid 400, and the scraping and heating tube is assembled in the heating tube installation groove 450. After the ice cubes in the ice-making grid 400 are formed, they can be heated by the scraping and heating tube for a short time and then scraped out by a scraping rod 810.

[0026] To store the scraped ice cubes, an ice storage box 820 is further provided below the ice-making grid 400. An ice discharging motor and a pushing member are provided inside it. The ice cubes entering the ice storage box 820 are sent outwards under the pushing action of the pushing member driven by the ice discharging motor.

[0027] To achieve the refrigeration of the water in the ice tray 400, the ice maker structure is configured to include a heat pipe component 500, one end of which is connected to the ice tray 400 and arranged in contact with the ice tray 400, and the other end is in contact with the refrigeration system for heat exchange with the refrigeration system.

[0028] In some embodiments of the present application, it further includes: a heat pipe heat exchange component 522 for cooperating with the refrigeration system and exchanging heat with the refrigeration system; In some embodiments of the present application, the heat pipe component 500 includes: a heat pipe body 510, and connected to both ends thereof are: a condensation heat exchange part 520, the condensation heat exchange part 520 is arranged in contact with the heat pipe heat exchange component 522 and communicated with the heat pipe body 510; In the structure of the condensation heat exchange part 520, the condensation heat exchange part 520 communicated with the heat pipe body 510 is connected to the heat pipe heat exchange component 522, and heat exchange is carried out through surface contact between the heat pipe heat exchange component 522 and the refrigeration system, further increasing the heat exchange capacity of the heat pipe component 500.

[0029] a heat pipe evaporation part 530, which is communicated with the heat pipe body 510, connected to the ice tray 400 and arranged in contact with the ice tray 400.

[0030] In some embodiments of the present application, the heat pipe body 510 is a heat pipe main section, the condensation heat exchange part 520 is a condensation pipe section, and the evaporation pipe part is a corresponding evaporation pipe section. When connecting, the condensation pipe section and the evaporation pipe section are respectively connected to both ends of the heat pipe body 510 to form an integral heat pipe structure.

[0031] Specifically, the material of the heat pipe structure is selected as a metal pipe wall, such as pure copper material. A capillary structure 5412 is correspondingly arranged on the inner wall of the heat pipe component 500, a working medium for circulating flow is formed inside the heat pipe component 500, and a working medium flow cavity 511 for the working medium to circulate is provided.

[0032] In the heat pipe evaporation part 530 at the lower part of the heat pipe component 500, the working medium absorbs heat and evaporates, changing from a liquid phase to a gas phase, and absorbing the heat of the heat exchange surface such as the ice tray 400. After absorbing heat, the gaseous working medium, due to the decrease in its own density, flows upward in the working medium flow cavity 511 under the action of buoyancy until the heat pipe condensation section at the top of the heat pipe. At the heat pipe condensation section, the working medium releases heat, changes from a gas phase to a liquid phase, and transfers the latent heat of phase change to the position in contact with the heat pipe condensation section, such as the heat exchange surface on the ice making system. After the gaseous working medium releases heat, it condenses into a liquid and flows to the bottom of the heat pipe under the action of capillary action and its own gravity until the bottom heat pipe evaporation part 530, thus completing the circulation of the working medium in the heat pipe and the efficient transfer of heat. To reduce the working medium pressure and the exclusion of non-condensable gases in the heat pipe component 500, the heat pipe needs to be evacuated before filling with the circulating working medium.

[0033] Since the heat pipe has no moving parts as a whole and its appearance is a closed metal copper tube that can be bent, and it can achieve efficient heat transfer, its heat exchange performance is much higher than the heat transfer performance of a solid metal copper tube. Therefore, it can be used for direct cooling ice making on the door. By freely separating and combining the heat pipe component 500 of the ice making grid 400 and the refrigeration system, and optimizing the contact thermal resistance between the condensing heat exchange part 520 and the refrigeration system, the performance of the door ice maker can be greatly improved.

[0034] In this embodiment, a heat pipe heat exchange component 522 is provided, and the condensing heat exchange part 520 is attached and fixed to the heat pipe heat exchange component 522. The heat exchange contact area between the heat pipe component 500 and the refrigeration system is increased through contact and heat exchange between the heat pipe heat exchange component 522 and the refrigeration system, thereby improving the heat exchange efficiency.

[0035] When the door body 210 is in an open state, the heat pipe heat exchange component 522 is separated from the refrigeration system; Since the heat pipe heat exchange component 522 and the refrigeration system are in contact cooperation, and the heat pipe heat exchange component 522 and the ice making tray 400 are integrally assembled on the door body 210, when the door body 210 is opened, the heat pipe heat exchange component 522 can be separated from the refrigeration system, and at this time, the ice making tray 400 does not need to be refrigerated and ice-making.

[0036] When the door body 210 is in a closed state, the heat pipe heat exchange component 522 contacts and exchanges heat with the refrigeration system, so that the working medium inside the heat pipe component 500 flows and undergoes a phase change to cool the water in the ice tray.

[0037] After the door body 210 is closed, the heat pipe heat exchange component 522 can contact the refrigeration system. The heat pipe heat exchange component 522 receives the cold and transfers it to the condensation heat exchange part 520 arranged thereunder. The working medium in the condensation heat exchange part 520 undergoes a phase change so that it flows inside the heat pipe component 500 to the heat pipe evaporation part 530 for heat exchange, so as to freeze the water in the ice cube tray 400 and form ice cubes.

[0038] The specific working process of the ice maker is as follows: the refrigeration system of the refrigeration equipment cools the heat pipe heat exchange component 522 at the top of the ice maker, and the heat pipe heat exchange component 522 transfers the coldness of the refrigerator to the condensation heat exchange part 520. The temperature of the working medium in the heat pipe component 500 decreases, and the phase changes and condenses into a liquid state. Under the action of gravity and capillary action, it flows to the bottom of the heat pipe component 500, and after flowing to the heat pipe evaporation part 530 at the bottom of the ice making grid 400, the low-temperature liquid working medium absorbs the heat of the ice making grid 400, and after freezing the water in the ice making grid 400 into ice, the working medium in the heat pipe evaporation part 530 in the heat pipe component 500 absorbs heat and changes into a gaseous state.

[0039] The gaseous working medium at the center of the heat pipe flows toward the top of the heat pipe under the action of buoyancy due to its reduced density, and condenses into liquid in the condensation heat exchange part 520, completing the circulation of the working medium.

[0040] The cold energy of the refrigeration system of the refrigeration equipment is transferred to the ice making grid 400 by the heat pipe component 500, freezing the water in the ice making grid 400 into ice. The ice cubes are heated for a short time by the ice scraping heating pipe at the bottom of the ice making grid 400, and then the ice cubes are scraped out by the ice stripping rod. After water is refilled into the ice making grid 400, the next ice making cycle is repeated.

[0041] The ice-making machine installed on the refrigeration equipment adopts the heat pipe component 500 structure. The circulating working medium is arranged inside the heat pipe component 500. The self-circulation of the working medium and the conversion of the gas-liquid phase can be realized in the working medium flow cavity 511. It is sufficient to ensure that the condensation heat exchange part 520 of the heat pipe component 500 is in contact with the refrigeration system for heat exchange. Therefore, the entire ice-making machine structure can be transferred from the refrigeration chamber to the door body 210 during assembly. When the door 210 is closed, the heat pipe component 500 and the refrigeration system can maintain heat exchange to quickly and efficiently make ice for the water in the ice cube tray 400 through the phase change of the working medium inside the heat pipe component 500; When the door body 210 is opened, the heat pipe component 500 and the refrigeration system can be separated without affecting the normal use of the user.

[0042] In the ice-making machine structure of this embodiment, the heat pipe component 500 is used to replace the ice-making evaporation pipe 340. The heat pipe component 500 and the refrigeration system are contact-coordinated to realize the assembly of the ice-making machine on the door body 210, thereby reducing the occupation of the internal space of the box body 110 and increasing the storage space inside the box body 110. When the ice maker is making ice, the internal working fluid undergoes a phase change after coming into contact with the refrigeration system through the heat pipe component 500 and circulates to the heat pipe evaporator 530 to exchange heat with the ice cube tray 400. The heat exchange between the heat pipe component 500 and the refrigeration system is a direct contact heat exchange, which ensures the heat exchange effect, and further ensures the ice-making speed and ice-making effect for the ice cube tray 400, thereby realizing the door-mounted assembly of the ice maker while ensuring the ice-making effect.

[0043] The ice maker uses a heat pipe component 500, which is in contact with the refrigeration system. When the user opens or closes the door, the heat pipe component 500 is automatically separated, and the heat pipe component 500 will not be damaged or fatigued. Moreover, since the heat pipe component 500 is in contact with the refrigeration system, when the door body 210 rotates around the door hinge, the heat pipe component 500 will not interfere with each other as in the existing evaporation pipe structure. Secondly, the heat pipe component 500 and the ice making grid 400 are made into an integrated structure. Compared with the existing ice making evaporation pipe 340 which needs to be assembled with the ice making grid 400 and connected to the refrigeration system and extends a certain length out of the foam layer of the box body 110, there is no need for an evaporation pipe extending into the foam layer of the box body 110, nor is it necessary to precisely assemble the ice making evaporation pipe 340, saving the complex assembly links of a common direct cooling ice maker and having high assembly efficiency; And it is arranged on the door body 210 for convenient maintenance, with good maintainability and good product quality stability.

[0044] In some embodiments of the present application, the heat pipe heat exchange component 522 is a heat pipe heat exchange plate, and a first mating surface 5221 adapted to contact the refrigeration system is formed at the top thereof, and the first mating surface 5221 is a plane; Setting the first mating surface 5221 as a plane can ensure the flatness of the upper surface of the first mating surface 5221, ensure good contact with the refrigeration system of the refrigeration equipment, and prevent poor contact or gaps from occurring, which may affect heat dissipation.

[0045] The heat pipe heat exchange component 522 is provided with the first mating surface 5221, which can also ensure a large contact mating surface 544 with the refrigeration system, resulting in good heat exchange effect; The heat pipe heat exchange plate is arranged obliquely, and there is a first included angle between it and the horizontal plane, and the angle of the first included angle is 3 - 5 degrees.

[0046] To ensure its close contact with the refrigeration system of the refrigeration equipment, the heat pipe heat exchange plate at the top is arranged obliquely with a certain inclination angle, so that the first mating surface 5221 above it is also set at the inclination angle of the first included angle.

[0047] The heat pipe evaporation part 530 is arranged obliquely, and it includes: A first end near the body thereof; And a second end far from the heat pipe body 510, and the height of the second end is lower than the height of the first end; Setting the heat pipe evaporation part 530 such that the height of the end near the heat pipe body 510 is greater than the height of the end far from the heat pipe body 510 can make the entire heat pipe evaporation part 530 have an upward inclination angle of about 3°, facilitating the upward flow of the gaseous working medium, increasing the working medium circulation rate, and improving the heat exchange efficiency.

[0048] In some embodiments of the present application, the ice making grid 400 includes: An ice making grid bottom member 430, which constitutes the bottom surface of the ice making grid 400. The ice making grid bottom member 430 is a bottom plate component of the ice making grid 400, and the bottom surface of the ice making grid bottom member 430 is an inclined surface arranged obliquely; It has a second included angle with the horizontal plane, and the angle of the second included angle is 3-5 degrees. The heat pipe evaporation part 530 is arranged in contact with the bottom member 430 of the ice-making grid.

[0049] Since the heat pipe evaporation part 530 is arranged in contact with the bottom member 430 of the ice-making grid, when the bottom surface of the bottom member 430 of the ice-making grid is arranged obliquely, the bottom member 430 of the ice-making grid arranged above it forms a second included angle arrangement, so as to facilitate the upward flow of the gaseous working medium located in the heat pipe evaporation part 530.

[0050] In some embodiments of the present application, one heat pipe component 500 is provided. The condensation heat exchange part 520 is bent and arranged along the length or width direction of the heat pipe heat exchange component 522, and is fixedly welded to the heat pipe heat exchange component 522.

[0051] Setting one heat pipe component 500 to cooperate with the refrigeration system and the ice-making grid 400 respectively can save the assembly space.

[0052] To increase the heat exchange area between the heat pipe heat exchange component 522 and the condensation heat exchange part 520, the condensation heat exchange part 520 is bent and arranged on the heat pipe heat exchange component 522, and is evenly laid on the heat pipe heat exchange component 522 in the form of multiple bent sections.

[0053] Welding the heat pipe heat exchange component 522 and the condensation heat exchange part 520 fixedly can reduce the contact thermal resistance of the heat exchange system and improve the heat exchange efficiency.

[0054] In some embodiments of the present application, to increase the contact area between the heat pipe component 500 and the heat exchange surfaces of the ice-making grid 400 and the heat pipe heat exchange component 522, the heat pipe component 500 is pressed into a flat shape such as an oval or a rectangle.

[0055] Only one heat pipe component 500 is provided on the entire ice-making grid 400 to achieve heat exchange with the refrigeration system, and the overall cost is low.

[0056] In some embodiments of the present application, the ice-making grid 400 includes: a bottom member 430 of the ice-making grid, which constitutes the bottom surface of the ice-making grid 400; and a side member 440 of the ice-making grid surrounding the periphery of the bottom surface of the ice-making grid 400, which constitutes the side surface of the ice-making grid 400; The bottom member 430 of the ice-making grid is the bottom plate of the ice-making grid 400, and it is arranged at the bottom position of the ice-making grid 400; The side member 440 of the ice-making grid is the side plate of the ice-making grid 400, and it is arranged on the side surface of the ice-making grid 400.

[0057] The bottom member 430 of the ice-making grid and the side member 440 of the ice-making grid constitute the entire ice-making grid 400, and the water injected into the ice-making grid 400 exists inside the ice-making grid 400.

[0058] One heat pipe body 510 is provided, and the heat pipe evaporation part 530 is arranged on the bottom member 430 and / or the side member 440 of the ice making grid, and is bent and arranged along the length direction or the width direction of the corresponding member and welded and fixed to the corresponding member.

[0059] To cool the water in the ice making grid 400, the heat pipe evaporation part 530 of the heat pipe body 510 can be arranged in close contact with the side of the ice making grid 400, that is, arranged on the side member 440 of the ice making grid, to cool the water in the ice making grid 400 from the side; Or the heat pipe evaporation part 530 is in close contact with the bottom member 430 of the ice making grid, to cool the water in the ice making grid 400 from the bottom.

[0060] Or part of the heat pipe evaporation part 530 is arranged on the side member 440 of the ice making grid, and part extends from the side member 440 of the ice making grid to the bottom member 430 of the ice making grid, to cool the water in the ice making grid 400 on the side and the bottom at the same time.

[0061] The bottom member 430 and / or the side member 440 of the ice making grid are welded and fixed to the heat pipe evaporation part 530, so that the ice making grid 400 and the heat pipe component 500 form an integral structure, which can effectively reduce the heat transfer thermal resistance between the ice making grid 400 and the heat pipe component 500, thereby reducing the heat transfer temperature difference and improving the ice making efficiency and ice making speed.

[0062] In addition, welding the ice making grid 400 and the heat pipe component 500 into an integral structure can also avoid secondary assembly in the refrigeration equipment workshop, and improve production efficiency and product quality.

[0063] In some embodiments of the present application, a plurality of heat pipe components 500 are provided, and the plurality of heat pipe components 500 are arranged in parallel, and the distance between adjacent heat pipe bodies 510 is the same or different; By arranging a plurality of heat pipe components 500 to be in contact and cooperate with the heat pipe heat exchange component 522 and the ice making grid 400 respectively, the heat exchange area between the heat pipe component 500 and the heat pipe heat exchange component 522 and the ice making grid 400 can be increased, and the heat exchange efficiency can be improved.

[0064] Specifically, the condensation heat exchange parts 520 of the plurality of heat pipe components 500 are arranged in parallel at the bottom of the heat pipe heat exchange component 522 and welded and fixed to the heat pipe heat exchange component 522, and the distance between adjacent condensation heat exchange parts 520 is the same or different.

[0065] The condensation heat exchange parts 520 are welded side by side on the lower surface of the top heat pipe heat exchange component 522. The welding method increases the heat exchange efficiency at the condensation heat exchange parts 520 and increases the strength of the whole component at the same time.

[0066] In some embodiments of the present application, a plurality of heat pipe bodies 510 are provided, and the plurality of heat pipe bodies 510 are arranged in parallel, and the distances between adjacent heat pipe bodies 510 are the same or different; A plurality of heat pipe evaporation parts 530 are arranged on the bottom member 430 and / or the side member 440 of the ice tray, and the plurality of heat pipe evaporation parts 530 are arranged uniformly along the length or width direction of the corresponding member.

[0067] That is, when a plurality of heat pipe components 500 are provided, the corresponding plurality of heat pipe evaporation parts 530 can be arranged on the bottom member 430 of the ice tray, or can be arranged on the side member 440 of the ice tray to perform heat exchange with the ice tray 400; Of course, during the setting, some heat pipe evaporation parts 530 can also be arranged on the side member 440 of the ice tray, and some heat pipe evaporation sections can be arranged on the side member 440 of the ice tray to ensure sufficient heat exchange with the ice tray 400 and improve the ice making efficiency.

[0068] During fixation, the multi-section heat pipe evaporation parts 530 can be directly welded and fixed to the ice tray 400 to reduce the heat transfer resistance.

[0069] In some embodiments of the present application, in order to firmly fix the heat pipe component 500, a plurality of heat pipe installation grooves 450 are provided at the bottom of the ice tray 400, and the plurality of heat pipe installation grooves 450 are arranged in parallel along the length direction of the ice tray 400; Or arranged in parallel along the width direction of the ice tray 400; A plurality of heat pipe evaporation parts 530 are respectively arranged in the plurality of heat pipe installation grooves 450 and are welded and fixed to the heat pipe installation grooves 450.

[0070] By providing the heat pipe installation grooves 450 on the ice tray 400, the welding of the heat pipe component 500 to the ice tray 400 can be facilitated.

[0071] After the heat pipe component 500 is installed in the heat pipe installation groove 450, it is fixed to the ice tray 400 by welding, so that the heat pipe component 500 and the metal ice tray form an integral structure, effectively reducing the heat transfer resistance between the ice tray 400 and the heat pipe component 500, thereby reducing the heat transfer temperature difference and improving the ice making efficiency and ice making speed.

[0072] Since the heat pipe evaporation part 530 is arranged in an upward inclined manner, in order to adapt to the heat pipe evaporation part 530, the heat pipe installation groove 450 also matches an inclination angle of about 3° to ensure the correct installation of the heat pipe.

[0073] For the number of heat pipes arranged side by side, it can be set according to the actual size of the ice maker. In some embodiments of the present application, the outer diameter of the heat pipe is 6-8 mm, and the number is 5-6. Of course, the heat pipe component 500 and the number can also be other specifications of heat pipes and numbers, which will not be elaborated here.

[0074] In some embodiments of the present application, the structure of the heat pipe component 500 is as follows: It includes a heat pipe body 510, and a working fluid flow cavity 511 is formed inside it; The heat pipe body 510 is a body pipe, and there is 1 root of it; And a condensation header part 540 connected to one end of the heat pipe body 510, which is in contact and cooperation with the refrigeration system, can exchange heat with the refrigeration system to drive the phase change of the working fluid in the condensation header part 540; Multiple capillary condensation channels 541 are formed inside it. The multiple capillary condensation channels 541 are arranged side by side along the length or width direction of the condensation header part 540, and the multiple capillary condensation channels 541 communicate with the working fluid flow cavity 511; In some embodiments of the present application, the condensation header part 540 includes a condensation header part member 543, and multiple said capillary condensation channels 541 are formed inside the condensation header part member 543; Or, multiple installation channels are provided inside the condensation header part member 543, capillary condensation pipes are arranged in the multiple installation channels, and the capillary condensation channels 541 are formed inside the capillary condensation pipes.

[0075] The capillary condensation pipe is a hollow pipe, which is assembled in the installation channel, and a capillary structure 5412 is laid on the pipe wall of the capillary condensation pipe to facilitate the return flow of the liquid working fluid in the heat pipe.

[0076] The condensation header part member 543 is a condensation header plate, which has a certain thickness, and the capillary condensation channels 541 are arranged inside the condensation header plate.

[0077] During molding, the capillary condensation channels 541 can be directly integrally formed with the condensation header part member 543; It can also be realized by installing capillary condensation pipes inside the condensation header part member 543.

[0078] An evaporation header part 550 connected to the other end of the heat pipe body 510 is arranged in close fit with the ice making grid 400. It can be arranged in close fit with the ice making grid 400 to exchange heat with the water inside the ice making grid 400, and has the effect of cooling the water inside the ice making grid 400 into ice.

[0079] Multiple capillary evaporation channels 551 are formed therein. The multiple capillary evaporation channels 551 are arranged along the length or width direction of the evaporation header part 550, and the multiple capillary evaporation channels 551 communicate with the working fluid flow chamber 511.

[0080] In some embodiments of the present application, the evaporation header part 550 includes an evaporation header component, and the multiple capillary evaporation channels 551 are arranged inside the evaporation header component; The capillary evaporation channels 551 can be arranged along the length direction of the evaporation header component; Or they can be arranged along the width direction of the evaporation header component, and no specific limitation is made here.

[0081] In this embodiment, the heat pipe component 500 improves the structures of the condensation heat exchange part 520 and the heat pipe evaporation part 530. The condensation heat exchange part 520 is set as the condensation header part 540, and a plurality of condensation capillary channels are arranged inside the condensation header part 540, so that the condensation header part 540 is a condensation header structure including multiple condensation capillary channels capable of heat exchange; Similarly, the heat pipe evaporation part 530 is set as the evaporation header part 550, making it an evaporation header structure including multiple evaporation capillary channels.

[0082] Setting the condensation heat exchange part 520 and the heat pipe evaporation part 530 as the condensation header structure and the evaporation header structure increases the number of heat exchange channels at the condensation heat exchange part 520 and the heat pipe evaporation part 530. Multi-channel heat exchange further increases the heat exchange area and improves the heat exchange efficiency; Both the condensation header part 540 and the evaporation header part 550 become an integrated heat pipe structure, which can place more heat pipes in the same space, saves the assembly space, and at the same time increases the heat exchange area with the refrigeration system and the ice making grid 400; One heat pipe body 510 is provided and is respectively communicated with the condensation header part 540 and the evaporation header part 550. The heat pipe body 510 is communicated with the condensation header part 540 and the evaporation header part 550, and can collect the multiple bundles of heat pipes flowing into it from the condensation header part 540 or the evaporation header part 550 together, reducing the material cost. Since the heat pipe body 510 as the working fluid transportation section does not participate in heat exchange, it has no influence on the ice making performance; For the entire heat pipe component 500, the multiple condensation capillary channels in the condensation header part 540 are integrated onto the condensation heat exchange part 520 component; The multiple evaporation capillary channels in the evaporation header part 550 are integrated onto the heat pipe evaporation part 530 component. On the premise of ensuring a large heat exchange contact area, the overall structure of the heat pipe component 500 is simplified. Compared with the structure of the multi-heat pipe component 500, the assembly is more simple and convenient, and the overall material cost is lower.

[0083] The structure of the integrated heat pipe component 500 is such that the entire heat pipe system is an integral whole. Vacuum pumping and working fluid filling are more convenient compared to an independent heat pipe system, which further reduces the system cost.

[0084] In some embodiments of the present application, the condensation header portion 540 further includes: A main condensation header 542, which is arranged to extend along the length or width direction of the condensation header portion 540, and is respectively connected to the working fluid flow chamber 511 and multiple capillary condensation channels 541, for transferring the working fluid to the multiple capillary condensation channels 541, or transferring the working fluid from the multiple capillary condensation channels 541 to the working fluid flow chamber 511; The main condensation header 542 is mainly used for the distribution or collection of the working fluid in each capillary condensation channel 541; The evaporation header portion 550 further includes a main evaporation header 552, which is arranged to extend along the length or width direction of the evaporation header portion 550, and is respectively connected to the working fluid flow chamber 511 and multiple capillary evaporation channels 551, for transferring the working fluid to the multiple capillary evaporation channels 551, or transferring the working fluid from the multiple capillary evaporation channels 551 to the working fluid flow chamber 511.

[0085] The main evaporation header 552 is mainly used for the distribution or collection of the working fluid in each evaporation condensation channel.

[0086] A main condensation header 542 and a main evaporation header 552 are respectively arranged at both ends of the heat pipe body 510.

[0087] Multiple condensation capillary channels are communicated with the main condensation header 542, and the main condensation header 542 is communicated with the heat pipe body 510; Multiple evaporation capillary channels are communicated with the main evaporation header 552, and the main evaporation header 552 is communicated with the heat pipe body 510.

[0088] After the working fluid in the multiple evaporation capillary channels exchanges heat, it can flow into the main evaporation header 552, flow into the heat pipe body 510 serving as the working fluid transportation section through the main evaporation header 552, be transported to the main condensation header 542 at the top, and be dispersed into each condensation capillary channel through the main condensation header 542.

[0089] The main condensation header 542 communicates with each distributed condensation capillary channel, and the main evaporation header 552 communicates with each evaporation capillary channel, which is convenient for the balance of the working fluid in the heat pipe and avoids the situation where the working fluid circulation speed in a certain heat pipe is too high while the working fluid circulation in other tube bundles is too low.

[0090] In this embodiment, multiple condensation capillary channels are integrated onto a condensation header component 543, which is a plate structure, and can increase the heat exchange area between the condensation header component 543 and the refrigeration system; Multiple evaporation capillary channels are integrated onto an evaporation header part 550, which is a plate part. This can increase the heat exchange area between the ice-making grid 400 and the evaporation capillary channels, improve the heat exchange efficiency, thereby enhancing the ice-making speed, reducing the ice-making energy consumption, and having a lower manufacturing cost at the same time.

[0091] The condensation header part 543 is in contact and cooperation with the refrigeration system, enabling it to automatically separate from the refrigeration system when the door is opened and to contact and exchange heat with the refrigeration system when the door is closed. This allows the working fluid in the heat pipe component 500 to circulate and undergo a phase change between the condensation capillary channels, the heat pipe body 510, and the evaporation capillary channels, refrigerating the water in the ice-making grid 400, achieving the door assembly of the ice maker, and reducing the occupation of the internal space of the cabinet 110; When the heat pipe component 500 is connected, it does not need to be connected to the refrigeration system. Therefore, there is no evaporation pipe extending out of the foaming layer of the cabinet 110, nor does it need to be assembled with the ice-making evaporation pipe 340 of the refrigerator. This saves the complex workshop assembly link of the ordinary direct cooling ice maker, has a high assembly efficiency, good maintainability, and good product quality stability.

[0092] In some embodiments of the present application, the condensation header part 543 is inclined, and the included angle between it and the horizontal plane is 3 - 5 degrees. A contact surface 544 for contact and cooperation with the refrigeration system is formed at the top, and the contact surface 544 is a plane, which is used to ensure its close contact and cooperation with the refrigeration system.

[0093] In some embodiments of the present application, the capillary condensation channel 541 includes a capillary channel body pipe 5411 and a capillary structure 5412 arranged on the inner wall of the capillary channel body pipe 5411. By setting the capillary condensation channel to have a smaller diameter and a capillary structure 5412 laid on the inner wall, the high-efficiency heat exchange between the working fluid and the refrigeration system can be ensured.

[0094] In some embodiments of the present application, the main condensation header 542 includes an interface part 545 for connecting with the heat pipe body 510. Along the direction from near the interface part 545 to far from the interface part 545, the channel inner diameters of multiple capillary condensation channels 541 gradually become larger.

[0095] The main condensation header 542 and the heat pipe body 510 are connected through the interface part 545. The working fluid flowing out of the heat pipe body 510 first enters the main condensation header 542. Among the multiple capillary condensation channels 541 connected to the main condensation header 542, the closer to the interface part 545, the shorter its flow path and the smaller the flow resistance; Similarly, the main evaporation header 552 and the heat pipe body 510 are also connected through an evaporation interface. Therefore, among the channels of multiple capillary evaporation channels 551, the closer to the evaporation interface, the shorter its flow path and the smaller the flow resistance; To balance the flow resistance between the capillary condensation channels 541, during the setting, the capillary condensation channels 541 can be set to have different inner diameters of different specifications.

[0096] For the capillary condensation channels 541 and the capillary evaporation channels 551 with shorter flow paths, their channel inner diameters can be appropriately reduced to increase their flow resistance, facilitating reaching a similar flow resistance to other channels and reducing the temperature difference generated between the channels.

[0097] In some embodiments of the present application, the ice tray 400 includes: an ice tray bottom member 430, constituting the bottom surface of the ice tray 400; and an ice tray side member 440 surrounding the periphery of the bottom surface of the ice tray 400, constituting the side surface of the ice tray 400; The evaporation header portion 550 is attached to the ice tray bottom member 430 and / or the ice tray side member 440.

[0098] That is, the evaporation header portion 550 can exchange heat with the ice tray 400 at the side surface of the ice tray 400; or exchange heat with the ice tray 400 at the bottom of the ice tray 400; Or, the evaporation header is arranged in a bent shape, with part attached to the ice tray side member 440 and part attached to the ice tray bottom member 430, and it contacts and exchanges heat with both the side surface and the bottom surface of the ice tray 400 simultaneously.

[0099] In some embodiments of the present application, the evaporation header portion 550 is arranged obliquely, and it includes a first evaporation header end 553, which is close to the heat pipe body 510; and a second evaporation header end 554, the second evaporation header end 554 is far from the heat pipe body 510, and the second evaporation header end 554 is lower than the first evaporation header end 553.

[0100] Arranging the end of the evaporation header portion 550 close to the heat pipe body 510 to be inclined upward can make the multiple capillary evaporation channels 551 inside it all arranged inclined upward, facilitating the upward flow circulation of the gaseous working medium.

[0101] In some embodiments of the present application, the bottom surface of the ice tray bottom member 430 is arranged obliquely, the evaporation header portion 550 is attached to the bottom surface of the ice storage box 820 and is arranged obliquely, and there is an included angle between the evaporation header portion 550 and the horizontal plane, and the included angle is 3 - 5 degrees.

[0102] In some embodiments of the present application, the cross-sectional shape of the capillary condensation channel 541 is oval or rectangular, and the cross-sectional shape of the capillary evaporation channel 551 is oval or rectangular to increase the heat exchange area.

[0103] In some embodiments of the present application, the refrigeration system further includes an ice-making evaporation member 300. The compressor, condenser, evaporator, ice-making evaporation member 300, and solenoid valve are connected through a refrigerant pipeline to form a refrigerant circulation flow path. The ice-making evaporation member 300 is used for contact heat exchange with the heat pipe component 500.

[0104] In some embodiments of the present application, the heat pipe component 500 includes: A condensation heat exchange part 520, which is in contact and cooperation with the ice-making evaporation member 300 for heat exchange with the refrigeration system; And a heat pipe evaporation part 530, which is bent to form the ice grid main body member 410, and a plurality of heat pipe evaporation micro-channels are formed in the heat pipe evaporation part 530; End blocking members 420, which are connected to both ends of the ice grid main body member 410 to form an ice-making grid 400 with an open top together with the ice grid main body member 410.

[0105] In some embodiments of the present application, the end blocking member 420 is an end baffle, which is fully welded to the ice grid main body member 410.

[0106] In some embodiments of the present application, the heat exchange evaporation part is an evaporation part forming plate, and the heat pipe evaporation micro-channels are directly formed in the evaporation part forming plate. When connected, it can be connected to the heat pipe body 510 through a header.

[0107] Alternatively, heat pipe evaporation micro-pipes are installed in the evaporation part forming plate, and a capillary structure is arranged in the heat pipe evaporation micro-pipes.

[0108] A working fluid for circulating flow is filled in the entire heat pipe component 500.

[0109] When the condensation heat exchange part 520 is in contact with the ice-making evaporation member 300, heat exchange occurs between the two. The internal working fluid circulates and flows into the plurality of heat pipe evaporation micro-channels at the heat pipe evaporation part 530, directly exchanges heat with the water located in the heat pipe evaporation part 530, absorbs heat, cools the water, and makes it into ice cubes.

[0110] The method of directly forming the heat pipe evaporation part 530 into the ice grid main body member 410 can enable the water to directly exchange heat with the working fluid, reduce the heat exchange thermal resistance, improve the heat exchange efficiency, achieve more efficient and rapid heat exchange, and achieve the effect of rapid and efficient ice making.

[0111] In some embodiments of the present application, the ice grid main body member 410 includes a bottom forming part 411 and side forming parts 412 bent from the bottom forming part 411.

[0112] When arranged, the heat pipe evaporation micro-channels extend along one of the side forming parts 412 to the bottom forming part 411 and extend out from the other side forming part 412.

[0113] In some embodiments of the present application, the ice maker includes a cantilever bracket 600, which is assembled on the door body 210 and extends into the inner space of the cabinet 110.

[0114] In some embodiments of the present application, the cantilever bracket 600 is a plastic part, which can deform after being compressed. And the cantilever structure of the cantilever bracket 600 can also ensure that there is a deformation space for its deformation and movement below it after being compressed.

[0115] In some embodiments of the present application, the heat pipe component 500 includes: A heat pipe evaporation part 530, which is fixed to the ice making grid 400 and arranged in close contact with the ice making grid 400; the heat pipe component 500 can be arranged in close contact with the side surface or the bottom surface of the ice making grid 400 during setting, and is directly welded and fixed to the ice making grid 400.

[0116] A condensation heat exchange part 520, which is assembled on the cantilever bracket 600 and used for contacting and cooperating with the ice making evaporation part 300; Wherein, when the door body 210 is closed, the ice making evaporation part 300 is pressed against the condensation heat exchange part 520 so that the adjacent surfaces of the condensation heat exchange part 520 and the ice making evaporation part 300 remain in close contact; During specific setting, there can be a certain interference amount between the ice making evaporation part 300 and the condensation heat exchange part 520 in the height position in the up-down direction, so that when the door body 210 rotates and closes, the ice making evaporation part 300 can squeeze the condensation heat exchange part 520 located below it.

[0117] Since the condensation heat exchange part 520 is assembled on the cantilever bracket 600, the cantilever bracket 600 is elastically deformable and there is a deformation space below it. When the ice making evaporation part 300 applies a pressing force to the condensation heat exchange part 520, the condensation heat exchange part 520 can deform through the cantilever bracket 600, so that finally the ice making evaporation part 300 is pressed against the condensation heat exchange part 520 and the adjacent surfaces of the two can remain in a close contact state.

[0118] When the door body 210 is opened, the condensation heat exchange part 520 slides relative to the ice making evaporation part 300 under the drive of the door body 210 and is separated from the ice making evaporation part 300.

[0119] By assembling the condensation heat exchange part 520 on the cantilever bracket 600 and setting it such that there is a certain interference amount in height between the ice-making evaporation part 300 and the condensation heat exchange part 520, it is ensured that when the door body 210 is closed, the ice-making evaporation part 300 can be pressed tightly against the condensation heat exchange part 520 and maintain a close fit with the condensation heat exchange part 520. Through the close fit between the adjacent surfaces of the condensation heat exchange part 520 and the refrigeration evaporation part 330, the contact thermal resistance can be greatly reduced, the heat exchange efficiency can be improved, and thus the cold quantity of the refrigeration system of the refrigeration equipment can be efficiently transferred to the ice maker, improving the ice-making efficiency.

[0120] When the door is opened, the ice maker is separated from the ice-making evaporation part 300 along with the door body 210, without affecting the functions of the original refrigeration equipment. Moreover, there are no moving parts in the entire ice-making system on the door, which is stable and reliable and can withstand 300,000 door opening and closing tests.

[0121] In some embodiments of the present application, the condensation heat exchange part 520 includes: a heat pipe heat exchange component 522; and a heat pipe condensation part 521 arranged on the heat pipe heat exchange component 522.

[0122] In some embodiments of the present application, the heat pipe component 500 includes a heat pipe body 510. The heat pipe evaporation part 530 is a heat pipe evaporation section, the heat pipe heat exchange component 522 is a heat pipe heat exchange plate, the heat pipe condensation part 521 is a heat pipe condensation section, and both the heat pipe evaporation section and the heat pipe condensation section are communicated with the heat pipe body 510.

[0123] In some embodiments of the present application, the heat pipe heat exchange component 522 is arranged obliquely, forming a certain angle with the horizontal plane, and the angle is 3 - 5 degrees; The ice-making evaporation part 300 is arranged obliquely, and its inclination direction and inclination angle are adapted to those of the heat pipe heat exchange component 522. When cooperating, the ice-making evaporation part 300 is pressed tightly against the heat pipe heat exchange component 522 and cooperates with the heat pipe heat exchange component 522.

[0124] Since there is a certain interference amount when the condensation heat exchange part 520 and the ice-making evaporation part 300 are set, and both the heat pipe heat exchange component 522 and the ice-making evaporation part 300 are arranged obliquely, the surfaces where they cooperate are in an inclined state, which can play a guiding role when the ice-making evaporation part 300 moves onto the heat pipe heat exchange component 522 and ensure that it can be pressed onto the heat pipe heat exchange component 522.

[0125] In some embodiments of the present application, the inner container component 220 includes: an inner container body part, on which a notch part 221 is formed. The ice-making evaporation part 300 is assembled at the position of the notch part 221, and it is closer to the condensation heat exchange part 520 than the inner container body part.

[0126] The inner container body part is an inner container body plate, and the notch part 221 is an installation notch formed on the inner container body plate.

[0127] In some embodiments of the present application, the notch part 221 is formed at the top position of the inner container body part.

[0128] The ice-making evaporation member 300 is installed at the notch part 221 and is closer to the condensation heat exchange part 520 than the inner container body part, that is, the inner side surface of the ice-making evaporation member 300 is arranged higher than the inner side surface of the inner container body plate, and it can be 2-3 mm higher than the inner side surface of the inner container body plate.

[0129] In this way, when the door body 210 is closed, it can be ensured that the condensation heat exchange part 520 first comes into contact and cooperation with the ice-making evaporation member 300, rather than fitting with the inner container body part, ensuring that heat exchange can be carried out by fitting between the ice-making evaporation member 300 and the condensation heat exchange part 520.

[0130] In some embodiments of the present application, the ice-making evaporation member 300 is blocked at the notch part 221 and is arranged in fit with the inner side surface of the inner container body part; that is, the outer contour of the ice-making evaporation member 300 is larger than the notch part 221, and during assembly, it is fixed in fit with the inner side surface of the inner container body part located in the storage space and blocks the notch part 221, and the notch part 221 can be used for passing refrigerant pipelines and the like.

[0131] Alternatively, the ice-making evaporation member 300 is inserted into the notch part 221, and the side surface of it located in the internal space of the box body 110 is closer to the condensation evaporation part than the side surface of the inner container body part located in the internal space of the box body 110.

[0132] Of course, the ice-making evaporation member 300 can also be set to have a certain thickness and its outer contour is adapted to the notch part 221, and it is inserted into the notch part 221, with part located outside the inner container component 220 and part located inside the inner container component 220.

[0133] In some embodiments of the present application, the door body 210 includes: a door panel external member 211, which constitutes the outer surface of the door body 210; a door panel internal member 212, which is connected to the door panel external member 211 and constitutes the internal partition of the door body 210, is located inside the box body 110, and the ice-making grid 400 and the cantilever bracket 600 are assembled on the door panel internal member 212.

[0134] The ice-making grid 400 is provided with screw locking holes, and the ice-making grid 400 can be fixedly locked on the door panel internal member 212 by screws.

[0135] In some embodiments of the present application, the cantilever bracket 600 includes: a bracket body part 610, and a locking part 620 for locking and fixing with the internal member of the door body 210 is provided on the bracket body part 610; The bracket body part 610 is a bracket body plate, which is horizontally arranged. The locking part 620 is a screw locking hole opened on the bracket body. The bracket body part 610 is locked and fixed on the internal component of the door body 210 by screws passing through the screw locking holes.

[0136] By locking the cantilever bracket 600 for locking and assembling the heat pipe component 500 to the door body 210, it can ensure that the whole ice maker can be firmly installed and fixed on the door body 210.

[0137] And a cantilever part 630 extending from the bracket body part 610 toward the internal space side of the box body 110, the cantilever part 630 is inclinedly arranged; The cantilever part 630 is a cantilever plate, which is integrally formed with the bracket body plate when formed.

[0138] An installation part 640 is formed on the cantilever part 630 for assembling the heat pipe heat exchange component 522; The installation part 640 is an installation groove formed on the cantilever part 630, and its contour shape is adapted to the heat pipe heat exchange component 522.

[0139] A limiting part 650 is formed around the installation part 640 for limiting the heat pipe heat exchange component 522 assembled inside it.

[0140] The limiting part 650 is a limiting protrusion formed on the circumference of the installation part 640. The heat pipe heat exchange component 522 is installed in the installation groove and is limited and fixed by the limiting protrusions around it; The heat pipe condensation part 521 is arranged at the bottom of the heat pipe heat exchange component 522 and is welded and fixed to the heat pipe heat exchange component 522. A clamping part 660 is formed on the bottom surface of the installation part 640. The clamping part 660 is used for clamping and fixing the heat pipe condensation part 521. The clamping part 660 is a clamping groove whose shape is adapted to the heat pipe condensation part 521.

[0141] In some embodiments of the present application, a plurality of the heat pipe components 500 are provided and arranged in parallel; A plurality of the clamping parts 660 are provided, formed on the bottom surface of the installation part 640, arranged side by side along the length or width direction of the heat pipe heat exchange component 522. The heat pipe condensation parts 521 of a plurality of the heat pipe components 500 are respectively clamped in a plurality of the clamping parts 660 and are limited.

[0142] That is, the arrangement mode of the heat pipe components 500 can be a plurality of heat pipe components 500. A plurality of clamping parts 660 are formed on the cantilever bracket 600 to position a plurality of heat pipe components 500, and the heat exchange efficiency is increased by a plurality of heat pipe components 500.

[0143] In some embodiments of the present application, one heat pipe component 500 is provided, and the corresponding heat pipe condensation part 521 is arranged in a bent shape along the length direction or the width direction of the heat pipe heat exchange component 522, and the clamping part 660 has a shape adapted to the shape of the heat pipe condensation part 521.

[0144] To reduce costs and ensure heat exchange efficiency, one heat pipe component 500 can be correspondingly provided, assembled on the cantilever bracket 600, and heat exchange is carried out by contacting the heat pipe heat exchange component 522 above it with the refrigeration evaporation part 330.

[0145] In some embodiments of the present application, the heat pipe heat exchange component 522 is a heat pipe heat exchange plate, and a first mating surface 5221 adapted to contact the ice-making evaporation part 300 is formed at the top thereof, and the first mating surface 5221 is a plane; The ice-making evaporation part 300 has an ice-making evaporation surface 320 that contacts and mates with the heat pipe heat exchange plate, and the ice-making evaporation surface 320 is a plane.

[0146] By setting both the first mating surface 5221 of the heat pipe heat exchange component 522 and the ice-making evaporation surface 320 of the ice-making evaporation part 300 as planes, it can be ensured that there is no gap between their contact and mating, and the heat transfer and heat conduction effects are good.

[0147] In some embodiments of the present application, a magnetic attraction assembly is further included, arranged between the ice-making evaporation part 300 and the condensation heat exchange part 520; Among them, when the door body 210 is closed, the ice-making evaporation part 300 and the condensation heat exchange part 520 are attracted to each other by the magnetic attraction assembly, and the adjacent surfaces are mutually attached to carry out heat exchange; When the door body 210 is opened, the condensation heat exchange part 520 is separated from the ice-making evaporation part 300 under the drive of the door body 210.

[0148] When the door body 210 is opened, the condensation heat exchange part 520 can be separated from the ice-making evaporation part 300 on the inner tank component 220. At this time, the ice maker stops making ice; When the door body 210 is closed, the adjacent surfaces of the condensation heat exchange part 520 and the ice-making evaporation part 300 are attached together to carry out heat exchange, so that the heat pipe evaporation section of the heat exchange component can cool the water in the ice-making grid 400.

[0149] The door body 210 of the refrigeration device may have a problem of sagging due to poor assembly or long-term use in the later stage, resulting in a gap between the adjacent surfaces of the ice-making evaporation part 300 and the condensation heat exchange part 520, and a problem of poor contact occurs.

[0150] The condensation heat exchange part 520 includes a heat pipe condensation part 521 and a heat pipe heat exchange component 522.

[0151] The ice maker uses a heat pipe for heat exchange, with high heat exchange efficiency. For the heat exchange efficiency of the ice maker, the greatest heat exchange resistance comes from the contact area between the heat pipe heat exchange component 522 and the refrigeration evaporation component 330 of the ice maker. The contact area and tightness are related to the ice making efficiency of the entire system. By adding a magnetic attraction assembly to the adjacent corresponding surfaces of the two components, it can ensure that the adjacent heat exchange surfaces are in stable contact when the refrigeration equipment door is closed, without being affected by factors such as the downward sag of the door body 210.

[0152] The magnetic attraction assembly includes: a magnetic component 710, which is arranged at the ice making evaporation component 300. To facilitate the assembly of the magnetic component 710, an embedding groove is also provided on the ice making evaporation component 300, and the magnetic component 710 is embedded in the embedding groove, with its top surface flush with the top surface of the ice making evaporation component 300.

[0153] A magnetic mating component 720, which is arranged at the condensation heat exchange part 520 and is used for attracting and fixing with the magnetic component 710.

[0154] A recessed groove can also be correspondingly provided on the heat pipe heat exchange component 522, and the magnetic mating component 720 is embedded in the recessed groove and kept flush with the heat pipe heat exchange component 522.

[0155] In some embodiments of the present application, the magnetic component 710 is a magnet or an iron part, and the magnetic mating component 720 is an electromagnet. After the electromagnet is energized, it generates a magnetic force and can be attracted and fixed with the magnet or iron part.

[0156] When the magnetic mating component 720 is an electromagnet, the electromagnet can be controlled by a controller to start after the door body 210 is closed. Specifically, the electromagnet starts 2 seconds after the door body 210 is closed, ensuring that when the door body 210 is closed, it will not be difficult to close due to the magnetic attraction force or cause friction damage to the ice making evaporation component 300 after multiple door openings.

[0157] When the user opens the door, since the distance between the electromagnet on the door body 210 and the reed switch in the end cover of the door body 210 increases, the attraction force weakens. When it is opened at a certain angle, the internal contacts of the reed switch are disconnected, and the main controller collects the door opening signal, and the electromagnet is powered off. The ice making evaporation component 300 is disconnected from the heat pipe heat exchange component 522, avoiding the generation of pulling force on both of them when opening the door.

[0158] When the door body 210 of the ice maker is closed, the electromagnet on the door body 210 and the reed switch in the door end cover are attracted, and the main controller recognizes it as the closed state of the door.

[0159] The electromagnet starts 2 seconds after the reed switch is attracted, reducing the aggravation of heat exchange surface friction caused by the magnetic attraction force.

[0160] The on-off state of the door body 210 is judged by the cooperation of the reed switch in the door end cover and the electromagnet; When the electromagnet attracts the reed switch, it is judged that the door body 210 is closed, and after a certain period of time, the electromagnet is turned on; When the electromagnet and the reed switch are separated, it is judged that the door body 210 is opened, and at this time, the electromagnet is controlled to cut off the power.

[0161] By controlling the start delay of the electromagnet, it can be ensured that when the door body 210 is closed, the problem of difficult closing due to magnetic attraction or mutual friction damage of the heat exchange surfaces of the ice-making evaporation part 300 and the condensation heat exchange part 520 after multiple door openings is avoided.

[0162] The magnetic component 710 is a first magnet, the first magnet can be a permanent magnet, the magnetic mating part 720 is a second magnet with the opposite polarity or an iron piece, and the iron piece can be an iron sheet or an iron block.

[0163] In some embodiments of the present application, the ice-making evaporation part 300 includes: An evaporation part 330, which has an ice-making evaporation surface 320 in contact and cooperation with the condensation heat exchange part 520; The evaporation part 330 is an evaporation plate, which can be inserted into the notch part 221 of the inner tank body part to realize the connection with the inner tank component 220.

[0164] The ice-making evaporation surface 320 can be used for fitting and cooperation with the heat pipe heat exchange component 522 of the condensation heat exchange part 520.

[0165] And an ice-making evaporation pipe 340 arranged in contact with the evaporation part 330, and the ice-making evaporation pipe 340 is connected to the refrigerant pipeline of the refrigeration system.

[0166] The ice-making evaporation pipe 340 is connected to the refrigeration system, so that the refrigerant can transfer the cold quantity to the evaporation part 330 through it.

[0167] In some embodiments of the present application, the ice-making evaporation pipe 340 is bent and arranged along the length or width direction of the ice-making evaporation part 300 and is fixedly welded to the ice-making evaporation pipe 340.

[0168] The ice-making evaporation pipe 340 can be selected as at least one copper pipe or aluminum pipe with an outer diameter of 6-8 mm, and it is attached to the back surface of the evaporation part 330.

[0169] To increase the heat dissipation area of the ice-making evaporation pipe 340, the ice-making evaporation pipe 340 is provided with a plurality of bent sections along the length or width direction of the evaporation part 330.

[0170] In some embodiments of the present application, the refrigeration system includes: a first connection pipeline 910, which is connected between the compressor and the solenoid valve, and a first throttling component 911 and the evaporator are sequentially arranged on the first connection pipeline 910; The second connecting pipeline 920, which is connected in parallel with the first connecting pipeline 910, is successively provided with a second throttling component 921 and the ice-making evaporation component 300 on the second connecting pipeline 920.

[0171] That is, the parallel connection of the ice-making evaporation component 300 and the evaporator is realized through the first connecting pipeline 910 and the second connecting pipeline 920.

[0172] The refrigerant flowing out of the condenser, after passing through the solenoid valve, a part enters the first connecting pipeline 910, passes through the first throttling component 911 and enters the evaporator, a part enters the second connecting pipeline 920 after passing through the solenoid valve, enters the second throttling component 921 and the ice-making evaporation component 300, and the refrigerant flowing out of the first connecting pipeline 910 and the second connecting pipeline 920 after heat exchange finally converges and flows into the compressor.

[0173] When the ice-making evaporation component 300 and the evaporator are completely connected in parallel, the ice-making of the ice maker and the refrigeration of the refrigeration system are completely separated. When the ice maker makes ice, the refrigeration does not work; when the refrigeration works, the ice maker does not make ice, avoiding the cold quantity redundancy in series and parallel connections and being more energy-efficient. However, it is required that the refrigeration speed of each circuit is fast and does not occupy the refrigeration time of the other circuit.

[0174] In some embodiments of the present application, the refrigeration system includes: A third connecting pipeline 930, which is connected between the solenoid valve and the evaporator, and a third throttling component 931 is arranged on the third connecting pipeline 930; A fourth connecting pipeline 940, which is connected between the solenoid valve and the evaporator, and a fourth throttling component 941 and a refrigeration evaporation component 330 are successively arranged on the fourth connecting pipeline 940, and the evaporator is connected to the compressor through a refrigerant pipeline.

[0175] A part of the refrigerant flowing out of the solenoid valve enters the third connecting pipeline 930 and exchanges heat with the ice-making evaporation component 300 through the third throttling component 931; A part enters the fourth connecting pipeline 940, passes through the fourth throttling component 941, and the refrigerant flowing out of the fourth throttling component 941 and the ice-making evaporation component 300 converges into the evaporator and then flows back to the compressor from the evaporator, realizing the series-parallel connection between the ice-making evaporation component 300 and the evaporator.

[0176] For a refrigeration device with an ice maker, connecting the ice-making evaporation component 300 and the evaporator in series and parallel can ensure that when the ice maker makes ice, the refrigeration device can also operate normally for refrigeration, and there will be no mutual interference between them.

[0177] In some embodiments of the present application, a plurality of first engaging fins 310 are formed on the ice-making evaporation member 300, and fin insertion channels 311 are formed between adjacent first engaging fins 310. A plurality of fin insertion channels 311 are formed among the plurality of first engaging fins 310; A condensation heat exchange part 520, on which a plurality of second engaging fins 523 are formed above it; Wherein, when the door body 210 is closed, the plurality of second engaging fins 523 are inserted into and contacted with the plurality of first engaging fins 310 to perform heat exchange; When the door body 210 is opened, the plurality of second engaging fins 523 slide and separate from the plurality of first engaging fins 310.

[0178] When the door body 210 is closed, the condensation heat exchange part 520 rotates synchronously with the closing rotation of the door body 210, driving the plurality of second engaging fins 523 above it to rotate. During its rotation, the plurality of second engaging fins 523 are continuously inserted into the plurality of fin insertion channels 311 formed between the plurality of first engaging fins 310; When the door body 210 is closed, the plurality of second engaging fins 523 are completely slidably inserted into the plurality of fin insertion channels 311, So that both sides of each second engaging fin 523 are in contact with the first engaging fins 310 at its two side positions, and the top is in contact with the ice-making evaporation member 300.

[0179] Compared with the existing way of only surface contact and cooperation between the ice-making evaporation member 300 and the condensation heat exchange part 520, the contact surface becomes the contact between the two side surfaces of the second engaging fin 523 and the side surfaces of the first engaging fin 310, and the top surface is in contact with the ice-making evaporation member 300. The second engaging tooth piece is completely wrapped by the cooperation of the first engaging fin 310 and the ice-making evaporation member 300, increasing the contact area between the two and improving the heat exchange efficiency.

[0180] When the door body 210 is opened, the plurality of second engaging fins 523 slide out along the fin insertion channels 311 to separate from the plurality of first engaging fins 310.

[0181] By arranging a plurality of first engaging fins 310 on the ice-making evaporation member 300 and arranging a plurality of second engaging fins 523 on the condensation heat exchange part 520, the first engaging fins 310 and the second engaging fins 523 can be adaptively matched. Through the cooperation of the first engaging fins 310 and the second engaging fins 523, it can also play a guiding role when the door body 210 is closed and when the door body 210 is opened, ensuring the smoothness of the opening and closing of the door body 210.

[0182] In some embodiments of the present application, the width of the fin insertion channel 311 gradually becomes smaller along the sliding insertion direction of the second engaging fin 523.

[0183] The inner diameter of the fin insertion channel 311 gradually decreases along the sliding insertion direction, which can ensure that its width is relatively wide during the initial insertion, facilitating the alignment and insertion of the second engaging fin 523 into the fin insertion channel 311.

[0184] In some embodiments of the present application, along the sliding insertion direction of the second engaging fin 523, the thickness of at least one of the two adjacent first engaging fins 310 gradually increases; When setting, the thickness of one of the first engaging fins 310 can be set to gradually increase in thickness, that is, the thickness is smaller closer to the entrance of the fin insertion channel 311, and the other first engaging fin 310 is set to have a uniform thickness. In this way, the width of the fin insertion channel 311 formed by the two first engaging fins 310 can also be gradually decreased.

[0185] By setting the first engaging fin 310 to have a structure that is narrow at the front and wide at the back, it is convenient for the initial engagement of the fins, and it can also reduce the resistance when the first engaging fin 310 and the second engaging fin 523 are engaged, avoiding mutual interference and being beneficial to assembly positioning.

[0186] Of course, when setting, the thicknesses of the two first engaging fins 310 can also be set to gradually change in thickness, and the corresponding thickness gradually decreases along the sliding insertion direction of the second engaging fin 523.

[0187] To achieve adaptation to the first engaging fin 310, along the sliding insertion direction of the second engaging fin 523, the thickness of at least one of the two adjacent second engaging fins 523 gradually decreases.

[0188] A second insertion channel for facilitating the insertion of the first engaging fin 310 is also formed between the two adjacent second engaging fins 523. During insertion, the first engaging fin 310 is inserted into the second insertion channel, and the second engaging fin 523 is correspondingly inserted into the fin insertion channel 311, realizing the mutual insertion and fitting contact between the first engaging fin 310 and the second engaging fin 523, ensuring a large heat exchange area.

[0189] In some embodiments of the present application, to realize the rotational connection of the door body 210 to the cabinet 110, the refrigeration device is further provided with a door hinge component 120, one end of which is fixedly connected to the cabinet 110, and the other end is rotationally connected to the door body 210 through a rotating shaft 130.

[0190] When the door body 210 is rotated to open or close, it rotates around the rotating shaft 130 as the rotation center to open or close.

[0191] To ensure that the first meshing fins 310 on the ice-making evaporation part 300 and the second meshing fins 523 on the condensation heat exchange part 520 can be normally meshed and separated, during the setting, the second meshing fins 523 are set as arc-shaped fins, and a plurality of the second meshing fins 523 are arranged in parallel in sequence, and the centers of the plurality of second meshing fins 523 coincide with the center of the rotating shaft 130.

[0192] When the door body 210 drives the ice maker to rotate, since the second meshing fins 523 are arc-shaped and the centers coincide with the center of the rotating shaft 130, the door body 210 also drives the second meshing fins 523 on the condensation heat exchange part 520 to rotate along the rotating shaft 130 to ensure normal insertion and fitting with the first meshing fins 310.

[0193] The first meshing fins 310 are arc-shaped fins adapted to the shape of the second meshing fins 523.

[0194] In some embodiments of the present application, the first meshing fins 310 are formed on the ice-making evaporation surface 320, and the second meshing fins 523 are formed on the heat pipe heat exchange component.

[0195] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0196] The above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
