Description

Technical Field

[0001] The invention relates to a household appliance, in particular to a refrigeration device. Background Art

[0002] With the continuous progress of society, more and more home appliances have entered people's lives. Among them, refrigerators, as an indispensable home appliance, make people's lives more convenient and comfortable. However, with the continuous advancement of technology, refrigerators have been given various additional functions in addition to their typical functions of long-term preservation and storage of food. For example, when users want to drink cool drinks or cook food, they often need to use ice cubes. Therefore, most refrigerators sold on the market are equipped with ice makers for making ice.

[0003] Most of the ice makers in existing refrigerators adopt a continuous water supply mode, that is, after the ice box completes ice making once, the water supply system injects water into the ice box to facilitate the ice box to make ice again. The quality of ice cubes depends to a large extent on the stability of the water supply system. When the water supply system causes fluctuations in the water injection amount due to voltage fluctuations, it will cause uneven distribution of water in the ice box, resulting in abnormal phenomena such as uneven ice size, splashing or ice cube connection. In severe cases, the ice maker will stop working, the product stability is poor, and the maintenance frequency is high. Summary of the invention

[0004] The object of the present invention is to provide a refrigeration device to solve the problems existing in the prior art that, during the process of supplying water to the ice box by the ice maker in the existing refrigeration device, the water flow rate is unstable, resulting in uneven quality of ice cubes, splashing, poor product stability and high frequency of equipment maintenance.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: The present application provides a refrigeration device, which comprises: Box; and an ice-making device, which is installed in the box, wherein: The ice making device comprises: A water supply assembly is installed in the box, comprising a water supply member, a water supply driving member connected to the water supply member, and a first pipe group connected to the water supply driving member, wherein the water supply driving member is used to transport water in the water supply member to the first pipe group; an ice-making assembly connected to the first tube assembly and used for making ice cubes from the fluid transported from the first tube assembly; A buffer assembly connected between the first tube assembly and the ice tray, the buffer assembly comprising: A buffer body, in which a buffer inner cavity is formed, and the buffer body is connected to the downstream end of the first tube group; A shutoff member connected to the output end of the buffer body, the shutoff member being connected to the ice tray through a second pipe group; Wherein, under the action of the water supply driving member, the fluid is output from the water supply member through the first tube group into the buffer inner cavity, and the fluid in the buffer inner cavity is transported to the ice-making assembly through the intercepting member.

[0006] The present application also proposes a refrigeration device, which comprises: Box; and an ice-making device, which is installed in the box, wherein: The ice making device comprises: A water supply assembly is installed in the box, comprising a water supply member, a water supply driving member connected to the water supply member, and a first pipe group connected to the water supply driving member, wherein the water supply driving member is used to transport water in the water supply member to the first pipe group; an ice-making assembly connected to the first tube assembly and used for making ice cubes from the fluid transported from the first tube assembly; a buffer assembly connected between the first tube assembly and the ice tray, the buffer assembly being used to temporarily store the fluid transported from the first tube assembly and slow down the instantaneous flow of the fluid into the ice tray; Under the action of the water supply drive, the fluid is output from the water supply component and transported to the ice-making component through the buffer component, and the total water supply Q of a water supply cycle satisfies: Q=V1*T1=V2*T2, wherein V1 is the instantaneous flow rate of the fluid flowing into the buffer component; V2 is the instantaneous flow rate of the fluid output from the buffer component; T1 is the working duration of the water supply drive, and T2 is the duration of a water supply cycle.

[0007] Compared with the prior art, the advantages and positive effects of the present invention are: The refrigeration device involved in the present application has a buffer component connected between the water supply component and the ice-making component, and the buffer component is used to temporarily store the fluid output from the water supply component and intercept the water flow input to the ice-making component to reduce the instantaneous flow of the water flow; In addition, in a water supply cycle T2, the specific working duration of the water supply drive is T1, and the instantaneous flow rate V2 flowing through the second tube group is set to satisfy: Q=V1*T1=V2*T2; the refrigeration equipment of the present application can control and interfere with the speed and stability of the fluid delivered to the ice-making component through the buffer body. When the water supply component is working, the excess fluid is temporarily stored in the buffer body. When the water supply component stops working, the interception component continues to supply water to the ice-making component in a continuous and stable manner, thereby overcoming the abnormalities of the traditional water circuit caused by unstable water flow.

[0008] In addition, a first protrusion is provided on the second pivot portion on the ice tray, and a second protrusion is provided on the inner wall of the connecting portion of the supporting vertical portion. During the flipping of the ice tray, the first protrusion and the second protrusion interfere with each other during the contact process, causing the ice tray to shake, which is beneficial to loosen the ice cubes in each ice making chamber in the ice tray. As the ice tray flips, the ice cubes can be dropped from the ice tray more thoroughly, and no additional deformation of the ice tray and other components occurs in this process, which is beneficial to increasing the service life of the refrigeration equipment and reducing the frequency of replacement and maintenance of the ice tray.

[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0013] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0014] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0015] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0017] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0018] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0019] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0020] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into 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.

[0021] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0022] like Figure 1 , Figure 2 The refrigeration device involved in the present application is specifically a refrigerator, which includes a box body 1. The refrigeration compartments in the box body 1 include a refrigerator compartment 2 and a freezer compartment. The front ends of the refrigerator compartment 2 and the freezer compartment are respectively provided with ports for introducing food.

[0023] A refrigerating door 4 and a freezing door 5 are respectively provided on the front side ports of the refrigerating chamber 2 and the freezing chamber. The refrigerating door 4 and the freezing door 5 are respectively hingedly connected to the cabinet 1 and are constructed to open or close the refrigerating chamber 2 and the freezing chamber.

[0024] like Figure 3 The freezer is used for freezing food. An ice-making device 3 is provided in the freezer for making ice cubes needed in life. The ice-making device 3 includes a water supply component 35, an ice-making component 31 and a buffer component 34. The water supply component 35 is externally connected to a water supply pipe for storing fluid transported from the water supply pipe and transporting the fluid to the ice-making component 31 in a quantitative manner as needed, so as to make ice with the ice-making component 31.

[0025] Combination Fig.11 The water supply component 35 is installed in the box 1 in an environment where the temperature range is above 0 degrees. The water supply component 35 includes a water supply part, a water supply drive part 36 and a first pipe group. The water supply part is used to store water, and the water supply drive part 36 outputs the water of the water supply part through the first pipe group.

[0026] The buffer assembly 34 is connected between the water supply assembly 35 and the ice-making assembly 31 , and is used to temporarily store the fluid output from the water supply assembly 35 and intercept the water flow input to the ice-making assembly 31 to reduce the instantaneous flow of the water flow.

[0027] The ice-making assembly 31 is connected to the first pipe assembly via the buffer assembly 34. The water buffered by the buffer assembly 34 is continuously output to the ice-making assembly 31 at a relatively small instantaneous flow rate to make ice cubes.

[0028] refer to Fig. 9 , Fig.10 The buffer assembly 34 includes a buffer body 341 and a shut-off member 343. A buffer inner cavity is formed in the buffer body 341, and the upper part of the buffer inner cavity is connected to the downstream end of the first pipe group.

[0029] The shutoff member 343 is connected to the output end of the buffer body 341 and is used to shut off the fluid transported from the buffer body 341 to the ice-making assembly 31 . The shutoff member 343 is connected to the ice-making tray 320 through the second tube group 32 .

[0030] The downstream section of the second tube group 32 passes through the insulation layer of the box body 1 and is connected to the top of the ice tray 320. A heating element is provided outside the downstream section of the second tube group 32 for heating the fluid in the second tube group 32 to prevent the internal water from freezing in the refrigerating chamber 2 and affecting the fluid transportation.

[0031] The shut-off member 343 is specifically a pipe with an inner diameter smaller than that of the first pipe group, or it can be a valve member arranged on the output end of the buffer body 341. The setting of the shut-off member 343 can ensure that the stored fluid in the buffer cavity is transported to the ice-making assembly 31 at a lower instantaneous flow rate.

[0032] The instantaneous flow rate of the fluid output from the water supply driving component 36 into the first tube group is defined as V1, and the instantaneous flow rate in the second tube group 32 after being throttled by the intercepting component 343 is defined as V2.

[0033] The water supply drive 36 injects water into the buffer assembly 34 in a continuous or intermittent manner. The specific work of the intermittent water injection, the number of water supplies and the single water supply duration are determined according to the actual needs of the user and the performance of the water supply drive 36.

[0034] And under the action of the shut-off member 343, the instantaneous flow rate V1 of the fluid flowing through the first tube group is greater than the instantaneous flow rate V2 flowing through the second tube group 32. Since the water supply drive 36 may fluctuate due to external factors such as voltage fluctuations during the water supply process, the instantaneous flow rate V1 of the first tube group in the present application is actually the average instantaneous flow rate V1 of the first tube group within the water supply time T1.

[0035] Corresponding to the instantaneous flow rate V2 in the second tube group 32, the opening size of the intercepting member 343 can be specifically designed to ensure that the second tube group 32 can stably supply water to the ice-making assembly 31 when the water supply driving member 36 is intermittently working or when the instantaneous water volume of the water supply driving member 36 fluctuates due to other factors.

[0036] The design of the buffer body 341 can control and interfere with the speed and stability of the fluid delivered to the ice-making assembly 31. When the water supply assembly 35 is working, excess fluid is temporarily stored in the buffer body 341. When the water supply assembly 35 stops working, the interception assembly continues to supply water to the ice-making assembly 31 in a stable manner, thereby overcoming the abnormalities of the traditional water circuit caused by unstable water flow.

[0037] A connecting portion is provided above the buffer body 341 , and the connecting portion is specifically an opening structure provided above the buffer body 341 , which is used to connect the buffer inner cavity with the outside, which can effectively avoid the flow siphon phenomenon and simplify the waterway control.

[0038] Specifically, a gradually contracting extension section is formed at the bottom of the buffer inner cavity, and the extension section is in a funnel shape to ensure that all water in the buffer inner cavity is discharged.

[0039] refer to Figure 4-Figure 7 The water supply component in the water supply assembly 35 includes a water tank 351 and a water tank cover 352. The top of the water tank 351 is open, and the water tank cover 352 is arranged on the top of the water supply component. The water tank cover 352 is provided with a water inlet 3524 for connecting with a water supply pipe.

[0040] Alternatively, an inlet cover 353 is detachably connected above the water storage inlet 3524, so that the user can disassemble it and manually fill water into the water storage tank 351.

[0041] A water storage cavity 3511 is formed in the water storage tank 351, and a water collecting recess 3512 extending downward is formed at the bottom of the water storage cavity 3511. The water supply drive 36 is connected to the water collecting recess to ensure that all the water in the water storage tank 351 is discharged.

[0042] Furthermore, in order to prevent splashing during the process of filling water into the water tank 351, a guide portion 3521 extending toward the buffer cavity is formed on the lower surface of the water tank cover 352, and a tapered guide channel is formed in the guide portion 3521. The guide channel is connected to the water storage cavity 3511. Then, the fluid output in the first pipeline is transported to the water storage cavity 3511 after passing through the guide channel. The guide channel guides and buffers the water flow, thereby reducing water spraying out from the water storage inlet 3524.

[0043] Referring to the figure, the water supply driving member 36 connected to the water storage cavity 3511 specifically includes a driving motor 362 and a water pump member 361 connected to the driving motor 362. The driving motor 362 is located outside the water storage tank 351, and the water pump member 361 extends into the water storage cavity 3511.

[0044] A first delivery pipe 3522 extending into the buffer inner cavity and a second delivery pipe 3523 extending outside the water supply member are also formed on the water storage tank cover 352. The first delivery pipe 3522 and the second delivery pipe 3523 are connected to each other.

[0045] The first delivery pipe 3522, the second delivery pipe 3523 and the water tank cover 352 are integrally formed, which improves assembly efficiency and helps to ensure the sealing of the connection between the first pipe group and the water supply component.

[0046] The first pipe group includes a first pipe section 363 and a second pipe section 364. The first pipe section 363 is used to connect between the water outlet port of the water pump component 361 and the first delivery pipe 3522 section. One end of the second pipe section 364 is connected to the second delivery pipe 3523, and the other end extends to the top of the connecting part or partially extends into the connecting part.

[0047] refer to Figure 8 The water supply assembly 35 is connected to the box body 1 through the support member 33, and the support member 33 includes a support frame 332 and a support cross frame 331 extending outward from the bottom of the support frame 332.

[0048] The bottom of the water supply component is connected to the supporting cross frame 331. The supporting cross frame 331 is a supporting plate structure with a press profile formed thereon to facilitate the positioning of the bottom of the water supply component and to enhance its supporting strength.

[0049] The supporting frame 332 is surrounded by supporting plates, and the driving motor 362 is fixed in the supporting frame 332 to protect the driving motor 362 .

[0050] The support plate at the top of the support frame 332 is a support auxiliary frame 3321 set at an angle, and a square connecting hole is opened on the support auxiliary frame 3321. The bottom of the buffer body 341 is connected to a bottom support plate 344, and a fixing hole is formed on the surrounding side of the bottom support plate 344. The bottom of the buffer body 341 passes through the connecting hole and is fixed to the support auxiliary frame 3321 through the bottom support plate 344.

[0051] The present application also proposes a refrigeration device, which includes a box body 1 , in which an ice-making device 3 is arranged. The ice-making device 3 includes a water supply component 35 , an ice-making component 31 and a buffer component 34 .

[0052] The water supply assembly 35 includes a water supply member, a water supply driving member 36 and a first tube group. The water supply driving member 36 is used to transport water in the water supply member to the first tube group.

[0053] The ice-making assembly 31 is connected to the first tube group and is used to make ice cubes from the fluid transported from the first tube group; The buffer assembly 34 is connected between the first tube assembly and the ice tray 320 . The buffer assembly 34 is used to temporarily store the fluid transported from the first tube assembly and slow down the instantaneous flow of the fluid flowing into the ice tray 320 .

[0054] Different from the above-mentioned embodiments, the structure of the buffer component 34 in the present refrigeration equipment can be a buffer body 341 structure that is funnel-shaped as a whole, or a cylindrical structure of other shapes, with a funnel-shaped buffer inner cavity formed inside, and the buffer inner cavity in the buffer body 341 can buffer the fluid flowing in from the first tube group.

[0055] A switch valve is formed at the bottom of the buffer body 341 , and the opening of the switch valve is adjustable to adjust the magnitude of the instantaneous flow output from the buffer body 341 to the ice-making assembly 31 .

[0056] Under the action of the water supply driving member 36, the fluid is output from the water supply member and transported to the ice-making assembly 31 through the buffer assembly 34, and the total water supply Q of one water supply cycle satisfies: Q=V1*T1=V2*T2.

[0057] Among them, V1 is the instantaneous flow rate of the fluid flowing into the buffer component 34; V2 is the instantaneous flow rate of the fluid output from the buffer component 34; T1 is the working time of the water supply drive 36, and T2 is the duration of a water supply cycle.

[0058] That is, a water supply cycle T2 is the total duration of fluid delivery during one ice-making process of the ice-making assembly 31 , which can also be understood as the total duration of water flow being delivered from the second tube assembly 32 to the ice-making assembly 31 once.

[0059] refer to Fig.12 In other embodiments, the ice-making assembly 31 includes a support base 310 , an ice-making tray 320 , an ice-making driving member 3101 , an ice storage member, an ice-detecting rod 3102 , and a temperature sensing member 3103 .

[0060] The support base 310 is used to connect the entire ice-making device with the freezing chamber. The support base 310 specifically includes a support transverse portion 311 and a support vertical portion 312 formed on the support transverse portion 311 and extending downward.

[0061] The supporting horizontal portion 311 is used to be connected to the top of the freezing chamber, and the ice tray 320 is connected to the supporting vertical portion 312 .

[0062] The supporting transverse portion 311 and the supporting vertical portion 312 may be a detachably connected structure, or may be formed in an integral plastic forming manner.

[0063] A plurality of reinforcing rib structures arranged vertically and horizontally are provided on the supporting transverse portion 311 and the supporting vertical portion 312 to improve the supporting strength of the supporting base 310 .

[0064] The ice tray 320 is used for making ice. A plurality of ice making chambers 321 with openings facing upward are formed on the ice tray 320 . The ice making chambers 321 are dispersedly arranged on the ice tray 320 in an array.

[0065] A first pivot portion is formed at the first end of the ice tray 320 , and a second pivot portion 322 is formed at the second end of the ice tray 320 . Under the rotation of the first pivot portion and the second pivot portion 322 , the ice tray 320 flips over and dumps the ice cubes in the ice making chamber 321 .

[0066] An ice storage member is also provided directly below the ice tray 320. The ice storage member is formed with an ice storage groove with an opening facing upward. When the ice tray 320 is turned over, ice cubes in the ice making chamber 321 fall into the ice storage groove.

[0067] The flipping of the ice tray 320 is driven by the ice driving member 3101. The top of the ice driving member 3101 is fixedly connected to the bottom of the supporting cross portion 311. A driving motor is arranged in the ice driving member 3101. The driving motor is connected to the first pivot portion through a transmission system. The ice tray 320 and the second pivot portion 322 are driven to rotate by driving the first pivot portion to rotate.

[0068] The first pivot portion and the second pivot portion 322 are respectively located at two opposite ends of the ice tray 320 and rotate synchronously with the ice tray 320 .

[0069] The first pivot portion and the second pivot portion 322 are respectively a section of an axis extending outward from the end of the ice tray 320. The first pivot portion and the second pivot portion 322 and the ice tray 320 are preferably formed integrally, so that the connection stability is strong and the processing efficiency is high.

[0070] The support stand 312 has a certain thickness. Along the thickness direction of the support stand 312 , the support stand 312 includes a first end surface close to the ice tray 320 and a second end surface away from the ice tray 320 .

[0071] A connecting portion 313 is formed on the supporting upright portion 312 . The connecting portion 313 is a through hole or a blind hole structure formed on the first end surface and extending toward the second end surface.

[0072] Specifically, refer to Figure 13-Figure 15 The second pivot portion 322 is rotatably connected to the connecting portion 313 via a connecting end 3223 , a first convex portion 3224 is formed on an outer wall of the second pivot portion 322 , and a second convex portion 314 is formed on an inner wall of the connecting portion 313 .

[0073] refer to Figure 16-Figure 20 In some embodiments of the present application, the outer wall of the connecting end 3223 is formed with a flat section and a shaking section along the circumference, and a plurality of first protrusions 3224 are arranged on the shaking section along the circumference. The ice-making tray 320 flips under the action of the ice-making driving member 3101. During the flipping process of the ice-making tray 320, the second protrusion 314 passes through the flat section and the shaking section in sequence.

[0074] The relative sizes of the first protrusion 3224 and the second protrusion 314 are such that the first protrusion 3224 and the second protrusion 314 may collide and interfere with each other to a certain extent during the rotation of the ice tray 320. However, since the overlapping portion between the first protrusion 3224 and the second protrusion 314 is small, the ice tray 320 will not be stopped by the second protrusion 314.

[0075] The structures of the first protrusion 3224 and the second protrusion 314 both involve a convex structure with a smooth surface, so that after the first protrusion 3224 and the second protrusion 314 come into contact and collide, as the second pivot portion 322 rotates, the first protrusion 3224 can pass through the second protrusion 314 more smoothly, thereby preventing the ice tray 320 from being subjected to excessive resistance from the second protrusion 314.

[0076] The relative positions of the shaking section and the ice tray 320 satisfy that when the ice tray 320 rotates downward by a certain angle, the second protrusion 314 passes through the shaking section, causing the ice tray 320 to shake during rotation, making it easier for ice cubes to fall off from the ice making chamber 321.

[0077] In other embodiments of the present application, a connecting end 3223 is formed on the second pivot portion 322, a flat zone and a shaking zone are formed on the inner wall of the connecting portion 313 along the circumferential direction, a plurality of second protrusions 314 are formed along the circumferential direction in the shaking zone, and the first protrusion 3224 is located on the connecting end 3223. The ice-making tray 320 flips over under the action of the ice-making drive 3101. During the flipping process of the ice-making tray 320, the first protrusion 3224 passes through the flat zone and the shaking zone in sequence.

[0078] The relative positions of the shaking area and the ice tray 320 meet the following requirements: Fig. 20 When the ice tray 320 rotates downward at a certain angle, the first protrusion 3224 passes through the shaking area, and the first protrusion 3224 and the second protrusion 314 interfere with each other. At this time, the ice tray 320 will also shake at a certain frequency, and the shaking will cause the ice cubes to loosen from the ice tray, thereby achieving a better ice-removing effect.

[0079] Reference again Fig.14 In some embodiments of the present application, in order to ensure a stable connection between the first pivot portion and the connecting portion 313, the second pivot portion 322 is divided into a positioning portion 3221, a middle section 3222 and a connecting end 3223 in a direction away from the ice tray 320.

[0080] Combination Fig.17 In the connecting portion 313, an intermediate area is formed between the second protrusion 314 and the first end face, the length of the intermediate area is a, the length of the intermediate section 3222 is equal to the length, and in the connected state, the intermediate section 3222 also extends into the connecting portion 313 and rotates in coordination with the connecting portion 313.

[0081] The sizes of the positioning portion 3221 , the middle section 3222 and the connecting end 3223 gradually decrease.

[0082] Specifically, the size of the middle section 3222 is adapted to the aperture of the connecting portion 313, the maximum size of the first protrusion 3224 is slightly smaller than the aperture of the connecting portion 313, and it is ensured that when the first protrusion 3224 and the second protrusion 314 contact, a certain degree of interference occurs between them to meet the jitter condition.

[0083] The middle section 3222 can improve the connection stability between the second pivot portion 322 and the supporting stand portion 312 to prevent loosening during rotation, and seal the opening of the connecting portion 313 to prevent foreign matter from entering.

[0084] In order to improve the wear resistance of the interference part, wear-resistant materials such as POM can be partially used at the first pivot part and the connecting part 313 to make the mechanical properties better and the structure more reliable.

[0085] The outer diameter of the positioning portion 3221 is larger than the connecting portion 313. In the connected state, the positioning portion 3221 is located outside the connecting portion 313. The end of the positioning portion 3221 is in contact with the first end surface of the supporting portion 312 to position the depth of the second pivot portion 322 extending into the connecting portion 313.

[0086] The ice tray 320 vibrates during the contact between the first protrusion 3224 and the second protrusion 314, which helps to loosen the ice cubes in each ice forming chamber in the ice tray 320. As the ice tray 320 flips, the ice cubes can be shaken off the ice tray 320 more thoroughly. No additional deformation of the ice tray 320 and other components occurs during this process, which helps to increase the service life of the refrigeration equipment and reduce the frequency of replacement and maintenance of the ice tray 320.

[0087] Reference again Fig.12 , Fig.13 The ice-making device also includes a control system. The ice-detecting rod 3102 and the temperature-sensing component 3103 are connected to the control system signal. The ice-detecting rod 3102 is arranged on one side of the ice-making driving component 3101 and can be driven by the ice-making driving component 3101 to rotate to detect whether there are ice cubes in the ice storage component.

[0088] When the ice detection rod 3102 detects that the amount of ice cubes in the ice storage part is above a preset value, the control system controls the ice-making device to stop making ice.

[0089] When the ice detection rod 3102 detects that the amount of ice cubes in the ice storage part is above a preset value, the control system controls the ice-making device to start making ice.

[0090] The temperature sensing component 3103 is arranged at the bottom of the ice tray 320, and is used to detect the temperature of the ice tray 320. When the temperature sensing component 3103 detects that the temperature at the bottom of the ice tray 320 drops to the preset temperature, it means that ice cubes are formed in the ice tray 320, and a signal indicating that ice making is completed can be transmitted to the control system. The control system controls the ice-making drive component 3101 to control the ice box to flip and shake off the ice cubes.

[0091] refer to Figure 21-Figure 27 In other embodiments of the present application, a lighting element 24 is provided in the refrigerator compartment 2 of the refrigerator to facilitate users to take and put items.

[0092] In order to prevent the lighting element 24 from being directly arranged on the side wall or the rear wall of the refrigerating chamber 2 and affecting the refrigerating space, the present application arranges the lighting element 24 on the rear side of the supporting shelf 21 .

[0093] Traditional shelf lighting cannot move the supporting shelf 21 at will due to the power connection, which makes it inconvenient to clean the refrigerator refrigerator compartment 2. The present application sets the lighting component 24 to a low-cost wireless connection. When the supporting shelf 21 is connected in place, the lighting component 24 is powered on. When the supporting shelf 21 is disassembled, the lighting component 24 is powered off, which is convenient for loading and unloading, cleaning and maintenance.

[0094] Specifically, refer to Fig.21 , Fig. 22 Support portions 22 are respectively formed on the two side walls of the refrigerating chamber 2 , and the two opposing support portions 22 have the same height. The support portions 22 are configured to be arranged along the depth direction of the refrigerating chamber 2 .

[0095] The support part 22 is specifically an upper support part and a lower support part arranged along the height direction of the side wall of the refrigerating chamber 2, and a support recess is formed between the upper support part and the lower support part. The two sides of the support shelf 21 are respectively inserted into the corresponding support recesses on both sides.

[0096] In some embodiments of the present application, the lighting component 24 connected to the supporting shelf 21 is connected to a power source via a power supply component, and the power supply component satisfies: when the supporting shelf 21 is in an installed state, the lighting component 24 is connected to the power supply component, and the lighting component can provide lighting for the cold storage room 2; when the supporting shelf 21 is in a non-installed state, the lighting component 24 is disconnected from the power supply component.

[0097] refer to Fig.25 , Fig.26 The lighting component 24 is an LED light board, and a mounting portion 213 is formed on the rear wall of the supporting shelf 21. The mounting portion 213 is a long strip-shaped mounting groove, and the lighting component 24 is connected in the mounting groove.

[0098] The opening of the mounting portion 213 faces the rear wall of the refrigerating chamber 2 , so as to prevent liquid such as condensed water in the refrigerating chamber 2 from affecting the lighting element 24 .

[0099] The material of the support frame 21 is transparent, so that the lighting element 24 can penetrate through it.

[0100] The power supply assembly specifically includes a female end connection portion 23 and a male end connection portion 211 which can be disconnected or connected according to the installation state of the support layer frame 21 .

[0101] When the support shelf 21 is in the installed state, the female connection part 23 and the male connection part 211 are in a connected state, the circuit in the power supply component is in an on state, and the lighting component 24 can illuminate the refrigerator compartment 2 of the refrigerator according to the user's usage requirements.

[0102] When the support shelf 21 is in a non-installed state, that is, when the support shelf 21 is removed from the cold storage chamber 2, the female connection part 23 and the male connection part 211 are in a disconnected state, the circuit in the power supply assembly is in a disconnected state, and the lighting component 24 is always in a power-off state.

[0103] Among them, reference Figure 24-Figure 27 The female end connection part 23 is formed on the rear wall of the refrigerating chamber 2, and the female end connection part 23 is connected to the power supply through a line. The male end connection part 211 is located on the rear side of the supporting shelf 21, and the male end connection part 211 is connected to the lighting component 24 through a line.

[0104] The male connection part 211 is matched with the female connection part 23 in position, and the male connection part 211 is connected or disconnected with the female connection part 23 as the supporting layer frame 21 moves, so as to facilitate the lighting element 24 to be powered on or off.

[0105] A switch is provided on the line between the female end connection part 23 and the power supply, and the switch is connected to the control system signal. The switch state of the refrigerated door body 4 is also connected to the control system signal. When the supporting shelf 21 is in the installed state, the female end connection part 23 and the male end connection part 211 are connected, and the lighting component 24 is connected to the power supply. When the refrigerated door body 4 is opened, the control system controls the switch to turn on, and the lighting component 24 is energized. When the refrigerated door body 4 is closed, the control system controls the switch to turn off, and the lighting component 24 is powered off.

[0106] Specifically, at least one static contact 231 is formed on the female end connection part 23, and at least one moving contact 212 extending toward the rear wall of the cold storage chamber 2 is formed on the male end connection part 211. In the installed state, the moving contact 212 is in contact and connected with the corresponding static contact 231.

[0107] In some embodiments of the present application, two static contacts 231 are arranged on the upper and lower parts of the female end connection part 23, and the static contacts 231 are separated by a first partition 233. Correspondingly, two moving contacts 212 are also arranged on the male end connection part 211, and the moving contacts 212 are separated by a second partition 214.

[0108] A connecting recess 215 that matches the size of the female connecting portion 23 is formed on the male connecting portion 211. The female connecting portion 23 is detachably connected in the connecting recess 215. The connecting recess 215 is specifically a groove structure with an opening toward the rear wall of the cold storage chamber 2. The female connecting portion 23 is inserted into the connecting recess 215 to prevent the liquid formed in the cold storage chamber 2 from damaging the connection, thereby improving the safety of the connection and playing a waterproof role.

[0109] An elastic member 232 is arranged between the static contact 231 and the female end connection part 23. During the connection process between the male end connection part 211 and the female end connection part 23, as the connection deepens, the moving contact 212 and the static contact 231 come into contact, and the elastic member 232 is compressed. The elastic member 232 can improve the tightness of the connection between the moving contact 212 and the static contact 231, and avoid the moving contact 212 and the static contact 231 from being misaligned or separated, which would affect the power supply of the lighting component 24.

[0110] In order to further improve the tightness of the connection between the female end connection part 23 and the male end connection part 211 , a sealing part 234 is formed on the outer wall of the female end connection part 23 , and a sealing groove 216 matched with the position of the sealing part 234 is formed on the inner wall of the connecting recess 215 .

[0111] The sealing portion 234 is a sealing ring structure arranged along the circumference of the female end connecting portion 23 , and the sealing groove 216 is an annular groove arranged in an annular shape in the connecting recess 215 .

[0112] During the connection between the male connecting part 211 and the female connecting part 23, the sealing part 234 on the female connecting part 23 is snapped into the sealing groove 216 on the male connecting part 211, further improving the sealing effect and preventing the moving contact 212 and the static contact 231 from contacting with external water.

[0113] The specific disconnection states of the male end connection part 211 and the female end connection part 23 are described in detail below: refer to Fig.28 , Fig.29 When the supporting shelf 21 is removed from the cold storage chamber 2, the male connection part 211 and the female connection part 23 are disconnected. Specifically, the moving contact 212 on the male connection part gradually moves away from the static contact 231 on the female connection part 23 until the moving contact 212 is completely separated from the static contact 231. At this time, the power supply line between the lighting component 24 and the power supply is completely cut off.

[0114] When the support shelf 21 is cleaned or overhauled, it is installed in the refrigerating chamber 2. Specifically, both ends of the support shelf 21 gradually extend to the rear end of the refrigerating chamber 2 along the support recesses on the two support portions 22 arranged on the side walls of the refrigerating chamber 2. As the support shelf 21 goes deeper, the moving contact 212 on the support shelf 21 gradually approaches the static contact 231 located on the rear wall of the refrigerating chamber 2.

[0115] When the moving contact 212 and the static contact 231 begin to contact, the support frame 21 is not fully installed. As the support frame 21 continues to move inward, the elastic member 232 at the other end of the static contact 131 is compressed a certain distance. Under the action of its own elastic force, the elastic member 232 can make the moving contact 212 and the static contact 231 directly contact stably.

[0116] The present application also proposes a refrigeration device, in which shaking may occur during the process of the ice tray 320 rotating and dropping ice cubes into the ice storage part.

[0117] The second pivot portion 322 fluctuates to a certain extent during the rotation in the connecting portion 313, causing the entire ice tray 320 to shake during the flipping process. As the shaking progresses, the ice cubes in each ice making chamber 321 on the ice tray 320 become loose from the ice making chamber, allowing the ice cubes to be more completely separated from the ice making chamber, thereby reducing the adhesion of the ice cubes to the ice making chamber and the incomplete falling of the ice cubes.

[0118] The first pivot part and the second pivot part 322 are respectively provided at both ends of the ice making tray 320 . The ice making driving member 3101 drives the entire ice making tray 320 to rotate through the first pivot part to dump the ice cubes in the ice making chamber 321 .

[0119] A connecting portion 313 is formed on the supporting portion 312 . The connecting portion 313 is a through hole or a blind hole structure. The second pivot portion 322 is inserted into the connecting portion 313 .

[0120] In order to realize the rotation of the ice tray 320 during the rotation process, the second pivot portion 322 and / or the connecting portion 313 are provided with a structure for interfering with the rotation of the second pivot portion 322 to a certain extent.

[0121] The interference structure interferes with the rotation of the second pivot portion to a certain extent, causing the rotation to vibrate, while ensuring that the rotation is not stopped.

[0122] A first protrusion 3224 is formed on the second pivot portion 322 , and a second protrusion 314 is formed on the inner wall of the connecting portion 313 .

[0123] The structures of the first protrusion 3224 and the second protrusion 314 both involve a convex structure with a smooth surface, so that after the first protrusion 3224 and the second protrusion 314 come into contact and collide, as the second pivot portion 322 rotates, the first protrusion 3224 can pass through the second protrusion 314 more smoothly, thereby preventing the ice tray 320 from being subjected to excessive resistance from the second protrusion 314.

[0124] The relative positions of the shaking section and the ice tray 320 satisfy that when the ice tray 320 rotates downward by a certain angle, the second protrusion 314 interacts with the first protrusion 314, so that the ice tray 320 shakes during the rotation, making it easier for ice cubes to fall off from the ice making chamber 321.

[0125] The ice device also includes an ice-detecting rod 3102 , a temperature-sensing component 3103 and a control system. The ice-detecting rod 3102 , the temperature-sensing component 3103 and the control system are connected by signals. The ice-detecting rod 3102 is connected to the ice-making driving component 3101 , and the temperature-sensing component 3103 is arranged at the bottom of the ice-making tray 320 .

[0126] When the temperature sensing element 3103 detects that the temperature at the bottom of the ice tray 320 drops to a preset temperature, the control system controls the ice driving element 3101 to control the ice box to flip and shake off the ice cubes.

[0127] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0128] The above are only 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 a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
