Description

Technical Field

[0002] At present, some refrigeration equipment is limited by the placement scenario, and generally requires the overall thickness to be as small as possible, but the effective volume to be as large as possible, so that it can be easily placed and can hold more items. For example, a small beauty refrigerator is generally placed on a bedside table or a dressing table to store beauty items. A small bedside table or a small dressing table cannot hold a thicker beauty refrigerator, which requires the overall thickness of the beauty refrigerator to be as small as possible, such as an overall thickness of 20 to 40 cm. Under the condition of a small overall thickness, the space occupied by the refrigeration component is required to be as small as possible, which can increase the effective volume of the beauty refrigerator and allow more items to be placed.

[0003] However, the refrigeration components of existing refrigeration equipment such as beauty refrigerators are generally directly installed on the rear wall, occupying a large dimension in the thickness direction, resulting in a low overall volume utilization rate of the refrigeration equipment.

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are 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 making creative work are within the scope of protection of this application.

[0060] The disclosure below provides many different embodiments or examples to implement different schemes of the present invention.

[0063] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0064] In order to solve the technical problem of low overall volume utilization of refrigeration equipment in the prior art, the present disclosure provides a refrigeration assembly, refrigeration equipment and a control method.

[0065] Among them, the present disclosure divides the refrigeration assembly into a sandwich device and a refrigeration device, the sandwich device is located at the rear of the refrigerated box and is attached to the rear wall of the refrigerated box, and the sandwich device and the refrigeration device are arranged vertically, and the lifting refrigeration plate of the refrigeration device can move vertically, so as to be inserted into or withdraw from the refrigeration plate placement groove of the sandwich device. When the lifting refrigeration plate is inserted into the refrigeration plate placement groove, the lifting refrigeration plate can transfer cold to the refrigerated box through the cold conduction sandwich, so as to refrigerate the refrigerated box. That is to say, the present disclosure realizes the separation of the refrigeration device and the refrigerated box through the separate design of the sandwich device and the refrigeration device, and the refrigeration device and the sandwich device are arranged vertically, so that the refrigeration device is arranged on one side of the refrigerated box in the vertical direction, and is no longer arranged on the rear side of the refrigerated box with the refrigeration assembly in the horizontal direction, and will no longer occupy the space on the rear side of the refrigerated box. Therefore, under the condition of a certain placement space, the scheme of the present disclosure can make the volume of the refrigerated box larger, thereby improving the volume utilization rate of the refrigeration equipment, so as to place more items in the refrigerated box.

[0066] In an exemplary embodiment, a refrigeration assembly, a refrigeration device and a control method thereof are provided. The refrigeration device may include a beauty refrigerator, a medical refrigerator or other refrigeration equipment, which is not limited. Figures 1 to 3 As shown, the refrigeration assembly may include an interlayer device 1 and a refrigeration device 2, the interlayer device 1 and the refrigeration device 2 are arranged vertically, and the interlayer device 1 is attached to the rear wall 31 of the refrigerated box 3. The refrigerated box 3 is a box for storing items in the refrigeration device. For example, when the refrigeration device is a beauty refrigerator, the refrigerated box 3 is a beauty box for storing beauty items, which can generally be placed on a placement table 100 such as a dressing table, a bedside table, etc.

[0067] Among them, the refrigeration device 2 includes a lifting refrigeration plate 21 that can move vertically, the interlayer device 1 includes a cooling interlayer 12 and a refrigeration plate mounting groove 11 for accommodating the lifting refrigeration plate 21, the cooling interlayer 12 is located between the refrigeration plate mounting groove 11 and the refrigerated box 3, and the lifting refrigeration plate 21 is inserted into or exited from the refrigeration plate mounting groove 11 by moving vertically.

[0068] Among them, the overall hardness of the lifting refrigeration plate 21 needs to ensure that it can be lifted vertically. The maximum height of the lifting refrigeration plate 21 does not exceed the height of the refrigerated box 3. For example, the height dimension can be 350mm-400mm, and its deformation is very small to ensure its smooth vertical movement.

[0069] Among them, the cooling interlayer 12 may include an aluminum plate made of an aluminum alloy material with a high thermal conductivity, and may also include a copper plate of a copper material, without limitation. Its thickness may be 5 mm, or may be other thicknesses, without limitation. It should be noted that the aluminum alloy material has good thermal conductivity and can effectively conduct cold. In addition, the outer dimensions of the cooling interlayer 12 are adapted to the rear wall 31 of the refrigerated box 3 to ensure a close fit to reduce heat loss during the transfer of cold. Among them, the surface of the cooling interlayer 12 away from the refrigerated box 3 can be finely frosted to make the surface roughness reach Ra0.8μm or less, so that the contact area with the lifting refrigeration plate 21 can be increased, further improving the efficiency of cold transfer.

[0070] It should be noted that the rear wall 31 of the refrigerated box 3 can be an aluminum plate or a copper plate. The density of the aluminum plate is smaller than that of the copper plate, which can reduce the weight of the refrigerated box 3. The heat transfer performance of the copper plate is better than that of the aluminum plate, which can improve the transfer effect of the cold amount.

[0071] Among them, the size of the lifting refrigeration plate 21 can be adapted to the refrigeration plate placement groove 11, and its length and width can be slightly smaller than the refrigeration plate placement groove 11, so that it can be smoothly inserted and withdrawn. In addition, the lifting refrigeration plate 21 can be made of pure copper, or copper-aluminum composite plate material, or other materials, which are not limited. When the lifting refrigeration plate 21 is made of copper-aluminum composite material, the copper layer can be located on the side in contact with the cold conduction interlayer 12, and the aluminum layer can be located on the side away from the cold conduction interlayer 12. The copper layer has excellent thermal conductivity and can quickly absorb and transfer cold, while the aluminum layer plays a certain supporting and protective role.

[0072] In some embodiments,

[0073] Vertical guide rails may be provided at the four corners of the lifting refrigeration plate 21. The guide rails may be made of stainless steel and matched with the guide rail grooves on the inner wall of the refrigeration plate placement groove 11, so that the lifting refrigeration plate 21 can move stably in the vertical direction. In addition, a refrigeration pipe may be provided inside the lifting refrigeration plate 21. The refrigeration pipe may be made of copper pipe and distributed in a serpentine shape along the length direction of the lifting refrigeration plate 21. The refrigeration pipe may be connected to the refrigeration source (such as a refrigeration system composed of a compressor, a condenser, etc.) in the refrigeration device 2. When the refrigeration system is started, the refrigerant circulates in the refrigeration pipe, absorbs heat and reduces the temperature of the lifting refrigeration plate 21, thereby generating cold.

[0074] It should be noted that the lifting refrigeration plate 21 may be in other forms besides the above forms. For example, the refrigeration device 2 may be refrigerated by semiconductors, and then transfer the cold energy to the lifting refrigeration plate 21, which then transfers the cold energy to the refrigerated box 3 through the cooling interlayer 12, thereby cooling the refrigerated box 3.

[0075] In addition, in this embodiment, the lifting refrigeration plate 21 can flexibly adjust its position according to the placement of the items in the refrigerated box 3, ensuring that the cold can be evenly transferred to each position in the box, avoiding the phenomenon of insufficient or overcooling of the local area due to the obstruction of the items. At the same time, the efficient refrigeration system of the refrigeration device 2 combined with the good thermal conductivity of the cold conduction interlayer 12 ensures that the refrigeration equipment can quickly reach and maintain the refrigeration temperature set by the user, providing a good refrigeration environment for the refrigerated items.

[0076] Among them, when the refrigerated box 3 has a refrigeration demand, the controller of the refrigeration equipment (not shown in the figure) can control the lifting refrigeration plate 21 to move vertically, so that the lifting refrigeration plate 21 is at least partially inserted into the refrigeration plate placement slot 11 of the interlayer device 1 to cool the refrigerated box 3. For example, a temperature setting button (which can be a virtual button or a physical button) can be provided on the refrigerated box 3, and relevant personnel can set the target temperature required by the refrigeration equipment through the above-mentioned temperature setting button. At the same time, the refrigeration equipment can also be provided with a temperature detection device (such as a temperature sensor), and the temperature detection device is used to detect the ambient temperature of the environment in which the refrigeration equipment is located. The temperature detection device can be, for example, set on the door body of the refrigerated box 3, or can be set at other locations, which is not limited. The controller can detect the ambient temperature through the above-mentioned temperature detection device, and can control the vertical movement distance of the lifting refrigeration plate 21 based on the above-mentioned target temperature and / or ambient temperature to adjust the size of the device inserted into the refrigeration plate placement slot 11, thereby realizing the control of refrigeration.

[0077] For example, the height L of the lifting refrigeration plate 21 can be controlled in the range of 0mm-300mm. When the target temperature is set to 15℃-18℃, or the ambient temperature is low (for example, lower than 20℃), it means that the cooling demand of the compartment of the refrigerated box 3 is small. At this time, the lifting refrigeration plate 21 is controlled to rise to a lower height, so that the size of the lifting refrigeration plate 21 inserted into the refrigeration plate placement slot 11 is smaller, and the contact area between the lifting refrigeration plate 21 and the cooling interlayer 12 is smaller, so that the cooling capacity transferred to the refrigerated box 3 is smaller. That is to say, in this embodiment, when other conditions remain unchanged, the target temperature is positively correlated with the size of the lifting refrigeration plate 21 inserted into the refrigeration plate placement slot 11, and the ambient temperature is positively correlated with the size of the lifting refrigeration plate 21 inserted into the refrigeration plate placement slot 11.

[0078] It should be noted that, in addition to controlling the size of the refrigeration plate 21 inserted into the refrigeration plate placement slot 11 based on the target temperature and / or the ambient temperature, other parameters may also be used for control, which is not limited thereto.

[0079] In this embodiment, the separation of the refrigeration device 2 and the refrigerated box 3 is achieved through the separation design of the interlayer device 1 and the refrigeration device 2. The refrigeration device 2 and the interlayer device 1 are arranged vertically, so that the refrigeration device 2 is arranged on one side of the refrigerated box 3 in the vertical direction, and is no longer arranged on the rear side of the refrigerated box 3 with the refrigeration components in the horizontal direction, and will no longer occupy the space on the rear side of the refrigerated box 3. Moreover, since the refrigeration device 2 is separated from the interlayer device 1, the interlayer device 1 can be set relatively thin, and even if it is attached to the rear side of the refrigerated box 3, the overall volume of the refrigerated box 3 is relatively small. Therefore, under the condition of a certain placement space, this embodiment can make the volume of the refrigerated box 3 larger, thereby improving the volume utilization rate of the refrigeration equipment, so that more items can be placed in the refrigerated box 3.

[0080] In an exemplary embodiment, a refrigeration assembly, a refrigeration device and a control method thereof are provided. In this embodiment, reference is made to Figures 1 to 3 as well as Figure 4 As shown, the interlayer device 1 and the refrigeration device 2 are detachably connected, for example, the two can be detachably connected by a snap connection, or by a magnetic connection, or by other methods, which are not limited to this.

[0081] Among them, since the sandwich device 1 and the refrigeration device 2 are detachably connected, when it is necessary to move the refrigerated box 3, the refrigeration device 2 and the sandwich device 1 can be disassembled, and the refrigerated box 3 and the sandwich device 1 can be moved alone, without moving the refrigeration device 2, so as to reduce the weight of the moved part and facilitate the movement of the refrigerated box 3. It should be noted that when it is necessary to disassemble and separate the sandwich device 1 from the refrigeration device 2, the lifting refrigeration plate 21 can be withdrawn from the refrigeration plate placement groove 11 first, so as to facilitate the removal of the refrigeration device 2 from the sandwich device 1.

[0082] The sandwich device 1 and the refrigerated box 3 may also be arranged to be detachably connected. The manner of the detachable connection may refer to the detachable connection manner between the sandwich device 1 and the refrigeration device 2, which will not be described in detail here.

[0083] Among them, since the interlayer device 1 and the cold box 3 can also be disassembled and separated, when the cold box 3 needs to be moved, the interlayer device 1 can be removed from the cold box 3, and the cold box 3 can be moved alone. There is no need to move the interlayer device 1 and the refrigeration device 2, which further reduces the weight of the moved part and makes it easier to move the cold box 3.

[0084] It should be noted that when disassembling the sandwich device 1 and the refrigerated box 3, the refrigeration device 2 can be first disassembled from the sandwich device 1, and then the sandwich device 1 can be disassembled from the refrigerated box 3, so as to avoid the refrigeration device 2 affecting the disassembly of the sandwich device 1 from the refrigerated box 3. Of course, the entirety of the refrigeration device 2 and the sandwich device 1 can also be directly disassembled from the refrigerated box 3, which can reduce the number of disassembly steps.

[0085] Among them, when the interlayer device 1 is removed from the refrigerated box 3, in order to ensure the thermal insulation of the back side of the refrigerated box 3, the refrigeration device may include a thermal insulation cover 4, and the thermal insulation cover 4 may be a foam board or other thermal insulation board, which is not limited. The back wall 31 of the refrigerated box 3 is provided with a first connecting member (not shown in the figure), and the thermal insulation cover 4 may be provided with a first matching member (not shown in the figure) that matches the first connecting member. The first connecting member cooperates with the first matching member to fit the thermal insulation cover 4 to the back wall 31 of the refrigerated box 3. In this way, after the interlayer device 1 is removed from the refrigerated box 3, the thermal insulation of the back side of the refrigerated box 3 can be improved by the thermal insulation cover 4 to prevent the cold in the refrigerated box 3 from being lost too quickly.

[0086] For example, the first connecting part may include an iron block, the first matching part may include a magnet, and the positions of the magnet and the iron block correspond to each other. The thermal insulation cover 4 and the refrigerated box 3 are connected by the attraction of the magnet and the iron block, and the thermal insulation cover 4 can be made to fit the rear wall 31 of the refrigerated box 3 to better prevent the coldness of the refrigerated box 3 from being lost too quickly.

[0087] It should be noted that, in addition to the above, the connection between the heat preservation cover 4 and the refrigerated box 3 can also be achieved by other methods, which are not limited to this. For example, the first connecting member and the first matching member can both be magnets to improve the reliability of the attraction.

[0088] In addition, in this embodiment, the side of the interlayer device 1 facing the refrigerated box 3 may be provided with a second matching piece (not shown in the figure) that matches the first connecting piece, and the first connecting piece and the second matching piece cooperate to fit the interlayer device 1 to the rear wall 31 of the refrigerated box 3. For example, the first connecting piece is an iron block, and the second matching piece is a magnet. The interlayer device 1 can achieve a detachable connection with the refrigerated box 3 by the magnet and the iron block on the refrigerated box 3. Based on this, there is no need to set an additional structure on the refrigerated box 3 to achieve a detachable connection with the interlayer device 1, and the structural design layout is more reasonable.

[0089] A sealing ring may be provided between the heat preservation cover 4 and the rear wall 31 of the refrigerated box 3 to further improve the heat preservation performance. A sealing ring may also be provided between the interlayer device 1 and the rear wall 31 of the refrigerated box 3 to prevent the cold from overflowing and better improve the refrigeration effect.

[0090] The side wall 32 of the refrigerated box 3 may be provided with a second connecting member 33, and the second connecting member 33 cooperates with the first matching member to fit the thermal insulation cover 4 to the side wall 32 of the refrigerated box 3. For example, the second connecting member 33 may include an iron block, and the first matching member may include a magnet, and the positions of the magnet and the iron block correspond to each other. The thermal insulation cover 4 and the refrigerated box 3 are connected by the attraction of the magnet and the iron block, and the thermal insulation cover 4 can be fitted to the side wall 32 of the refrigerated box 3, so as to facilitate the placement of the thermal insulation cover 4.

[0091] It should be noted that, in this embodiment, the positions and quantities of the first matching piece, the second matching piece, the first connecting piece and the second connecting piece 33 provided on the heat preservation cover 4 can be provided according to actual needs, and are not limited thereto. For example, for the first matching piece and the first connecting piece, when the heat preservation cover 4 is a square structure, a plurality of magnets can be provided on the side of the heat preservation cover 4 facing the refrigerated box 3, wherein two bar magnets and four block magnets, the two bar magnets are located at the upper and lower edges of the heat preservation cover 4, and the four block magnets are located at the four corners of the heat preservation cover 4. At the same time, two corresponding bar iron blocks and four block iron blocks are provided at the corresponding positions of the rear wall 31 of the refrigerated box 3, so as to better improve the connection reliability between the heat preservation cover 4 and the rear wall 31 of the refrigerated box 3.

[0092] In this embodiment, through the detachable connection design of the interlayer device 1, the refrigeration device 2, and the refrigerated box 3, when it is necessary to move the refrigerated box 3, different components can be selected to be disassembled according to actual conditions, which effectively reduces the weight of the moved part. Compared with traditional non-detachable refrigeration equipment, the manpower and material resources required for movement are significantly reduced, and the risk of equipment damage that may be caused during the movement is reduced.

[0093] In addition, the setting of the heat preservation cover 4 can effectively prevent the loss of coldness of the refrigerated box 3 after the interlayer device 1 is disassembled, and can prolong the maintenance time of the low temperature environment in the refrigerated box 3, which is beneficial to protecting the quality of the refrigerated items. Moreover, the connection between the components is achieved by the attraction of magnets and iron blocks, making the structural design of the refrigerated box 3, the interlayer device 1 and the heat preservation cover 4 more reasonable. The complex structural parts required by the traditional connection method, such as bolts, slots, etc., are reduced, the manufacturing cost is reduced, and the production efficiency is improved. At the same time, this simple structural layout is also convenient for daily maintenance and troubleshooting of the equipment. When problems occur in the equipment, the relevant components can be quickly disassembled for inspection and repair, which improves the overall reliability and service life of the equipment.

[0094] In an exemplary embodiment, a refrigeration assembly, a refrigeration device and a control method thereof are provided. In this embodiment, reference is made to Figures 1 to 3 as well as Figure 5 and Figure 6As shown, the cooling interlayer 12 may include a first cooling plate 121 and a second cooling plate 122. The materials of the first cooling plate 121 and the second cooling plate 122 may be the same or different, and there is no limitation on this. For example, the first cooling plate 121 and the second cooling plate 122 may both be copper plates.

[0095] A water storage tank 123 is formed between the first cold conducting plate 121 and the second cold conducting plate 122, and cooling water is stored in the water storage tank 123. The cooling water can better store the cooling energy transferred by the lifting cooling plate 21, thereby improving the cooling effect of the refrigerated box 3.

[0096] The first cold conducting plate 121 is attached to the lifting refrigeration plate 21, and the second cold conducting plate 122 is attached to the rear wall 31 of the refrigerated box 3. The cold energy of the lifting refrigeration plate 21 passes through the first cold conducting plate 121, the refrigerated water in the water storage tank 123, and the second cold conducting plate 122 in sequence, and then transfers the cold energy to the refrigerated box 3, providing cold energy for the refrigerated box 3.

[0097] Wherein, a spray device 34 is arranged in the refrigerated box 3, and the sandwich device 1 includes a first water suction pipeline 15, one end of the first water suction pipeline 15 is connected to the water storage tank 123, and the other end of the first water suction pipeline 15 is connected to the spray device 34 on the top of the refrigerated box 3, so as to provide cooling water for the spray device 34. For example, the spray device 34 may include a second water suction pipeline 341 and a spray head 342, one end of the second water suction pipeline 341 is connected to the spray head 342, and the other end is connected to the first suction pipe in the sandwich device 1. The spray head 342 can spray the cooling water in the water storage tank into the compartment of the refrigerated box 3 through the second water suction pipeline 341 and the first suction pipe, so as to cool and humidify the refrigerated box 3. A spray water pump 343 may be arranged in the second water suction pipeline 341, so as to better transfer the water in the water storage tank 123 to the spray head 342. The spray head 342 may be an ultrasonic spray head 342 or other types of spray heads 342, which are not limited. The spray head 342 is located in the middle of the top of the compartment to facilitate better spraying to the entire compartment. The size of the water mist sprayed by the spray head 342 can be adjusted, and the flow rate can also be adjusted to improve the control accuracy of the refrigeration.

[0098] That is to say, in this embodiment, the refrigeration equipment can not only provide cooling for the refrigerated box 3 through heat conduction between the lifting refrigeration plate 21, the first cold conduction plate 121, the cooling water and the second cold conduction plate 122, but also provide cooling for the refrigerated box 3 through the cooling water sprayed by the spray device 34, thereby better improving the refrigeration effect and the control accuracy of the refrigeration.

[0099] Among them, the refrigeration equipment may include a second fan 35, and the second fan 35 is used to drive the gas to flow in the compartment of the refrigerated box 3. For example, the second fan 35 can be arranged at the lower part of the refrigerated box 3, and the second fan 35 can be a centrifugal fan, and its blowing direction can be upward to better transport the cold air sinking from the bottom upward. When the refrigeration effect is good, the water in the water storage tank 123 can be quickly cooled to an ice-water mixture near 0°C. When the refrigeration equipment sprays the compartment of the refrigerated box 3 through the spray device 34, the temperature of the water mist sprayed from the spray head 342 can be between 0°C and 1°C. In this case, the second fan 35 can be started synchronously, and the disturbance is enhanced by the second fan 35 in the compartment, so that the low-temperature water mist can quickly contact the high-temperature air in the compartment, the compartment shelf, and the interior, thereby achieving rapid cooling.

[0100] Among them, the controller of the refrigeration equipment can control the wind speed of the second fan 35 in the refrigeration equipment based on the spray flow of the sprayed device 34 and the water temperature in the water storage tank 123, so as to more accurately realize the refrigeration of the refrigerated box 3. For example, when the spray flow is less than M1 and the water temperature of the water storage tank 123 is greater than T1, the second fan 35 can be controlled not to start, and the water mist settles naturally. When the spray flow is less than M1 and the water temperature is T less than T1, the second fan 35 can be controlled to run at a low wind speed (represented as V1). When M1≤spray flow≤M2, and the water temperature is greater than T1, the second fan 35 can be controlled to run at two wind speeds of V1 and V2 intermittently, where V2 is greater than V1. When M1≤spray flow≤M2, and the water temperature is less than T1, the second fan 35 can be controlled to run at a wind speed of V3, and V3 is greater than V2. When the spray flow is ≥M2, the second fan 35 can be controlled to run at the maximum wind speed V4, and V4 is greater than V3.

[0101] It should be noted that the specific values ​​of M1, M2, V1, V2, V3, V4 and T1 mentioned above can be set according to actual conditions and are not limited thereto. For example, T1 can be 1°C or other temperatures within the range of -5°C to 4°C and are not limited thereto.

[0102] In addition, in this embodiment, in addition to controlling the wind speed of the second fan 35, the accuracy of refrigeration control can also be improved by controlling the spray direction of the spray device 34. The controller can control the spray direction of the spray device 34 in the refrigerated box 3 based on the temperature on the left and right sides of the refrigerated box 3; the spray direction of the spray device 34 is toward the side with higher temperature. The temperature on the left side can be detected by a temperature sensing package set on the left side wall 32, and the temperature on the right side can be detected by a temperature sensing package set on the right side wall 32, or by other methods, which are not limited to this.

[0103] Among them, when the temperature on the left side is higher than the temperature on the right side, the spray head 342 of the spray device 34 can be controlled to face the left side wall 32, so that the spray direction is toward the left side of the compartment, so as to cool down the left side of the compartment of the refrigerated box 3 more quickly; when the temperature on the right side is higher than the temperature on the left side, the spray head 342 of the spray device 34 can be controlled to face the right side wall 32, so that the spray direction is toward the right side of the compartment, so as to cool down the right side of the compartment of the refrigerated box 3 more quickly; thereby, the uniformity of the temperature in the compartment can be better ensured.

[0104] Among them, the interlayer device 1 includes a second insulation layer 13, which is located on the side of the first cold conduction plate 121 away from the second cold conduction plate 122, and a cooling plate mounting groove 11 is formed between the second insulation layer 13 and the first cold conduction plate 121. The second insulation layer 13 can better prevent cold leakage and improve the cooling effect.

[0105] The sandwich device 1 includes a water inlet 16 for adding water to the water storage tank 123. The water inlet 16 is provided with a detachable sealing plug 17 to prevent debris from entering the water storage tank 123 and causing blockage or damage to the spray pipeline, thereby better ensuring the normal use of the spray function.

[0106] Among them, the refrigerated box 3 may include a water receiving tank 36 and a third water suction pipe 37, the water receiving tank 36 is located at the bottom of the refrigerated box 3, one end of the third water suction pipe 37 is connected to the water receiving tank 36, and the other end of the third water suction pipe 37 is connected to the water storage tank 123 in the interlayer device 1, which is used to transfer the cooling water in the water receiving tank 36 to the water storage tank 123.

[0107] After the compartment of the refrigerated box 3 is cooled by the spray function, the water mist condenses into water droplets and finally flows into the water receiving tank 36 at the bottom of the refrigerated box 3, and then is transferred to the water storage tank 123 through the third water suction pipeline 37, so as to realize the recycling of water. A water suction pump 38 may also be provided on the third water suction pipeline 37, so as to better transfer the water in the water receiving tank 36 to the water storage tank 123.

[0108] In this embodiment, the refrigeration equipment can achieve efficient refrigeration through the synergistic effect of the lifting refrigeration plate 21, the cooling interlayer 12, the spray refrigeration and the fan-assisted cooling. In different application scenarios, such as beauty refrigerators and medicine refrigerators, the temperature inside the box can be quickly reduced to the set range, effectively avoiding the risk of item deterioration due to uneven temperature.

[0109] In addition, the intelligent control strategy based on the spray flow rate, the water temperature of the water tank 123 and the temperature distribution in the box can accurately adjust the operating state of the refrigeration equipment. Both the wind speed of the fan and the spray direction of the spray head 342 can be dynamically adjusted according to actual needs, realizing the refined control of the refrigeration process, which can better ensure the storage quality of temperature-sensitive items such as beauty products and medicines.

[0110] Moreover, by spray-assisted refrigeration, the reliance on traditional refrigeration methods is reduced to a certain extent, and energy consumption is reduced. At the same time, water recycling is achieved through the water tank 36 and the water absorption pipeline, which reduces the waste of water resources, is more in line with modern energy-saving and environmental protection requirements, and can also reduce operating costs.

[0111] In an exemplary embodiment, a refrigeration assembly, a refrigeration device and a control method thereof are provided. In this embodiment, reference is made to Figures 1 to 3 as well as Figure 7 and Figure 8 As shown, the refrigeration device 2 may include a driving device 22, which is connected to the lifting refrigeration plate 21, and the driving device 22 is used to drive the lifting refrigeration plate 21 to move vertically. For example, when the position of the lifting refrigeration plate 21 needs to be adjusted, the controller can drive the lifting refrigeration plate 21 to move vertically by controlling the driving device 22.

[0112] The driving device 22 may include a driving gear and a driving motor (not shown in the figure), and the lifting refrigeration plate 21 includes a rack 211 matched with the gear, and the gear is meshed with the rack 211. The controller can drive the driving gear to rotate through the driving motor, and the rotation of the driving gear drives the rack 211 to move vertically, thereby driving the lifting refrigeration plate 21 to move vertically.

[0113] It should be noted that, in addition to adjusting the position of the lifting refrigeration plate 21 through the cooperation of the driving motor, the driving gear and the rack 211, the position of the lifting refrigeration plate 21 can also be adjusted through other driving devices 22, which is not limited to this.

[0114] Among them, the rack 211 can be made of the same material as the refrigeration plate body of the lifting refrigeration plate 21, or a different material can be used, without limitation. Two racks 211 can be set in the lifting refrigeration plate 21, or a single rack 211 can be set, without limitation. When two racks 211 are set, two corresponding sets of gears need to be configured. The two sets of gears can share the same drive motor, or they can be configured with a drive motor respectively, without limitation. The two racks 211 can be respectively located at the edges of the left and right sides of the lifting refrigeration plate 21 to improve the stability of the drive. Of course, the rack 211 can also be vertically arranged on one side edge of the lifting refrigeration plate 21, without limitation. The rack 211 can be made of high-strength alloy steel, which has good wear resistance and meshing performance, and cooperates with the drive gear to realize the lifting movement.

[0115] Among them, the driving motor, for example, can adopt a brushless DC motor, which has the advantages of stable speed, low noise, and long life. The output shaft of the motor is connected to the driving gear, and the forward and reverse rotation and speed of the motor are accurately controlled by the controller, so as to achieve precise control of the rotation of the driving gear. The driving gear can be, for example, an alloy steel gear, which is precisely meshed with the rack 211 of the lifting refrigeration plate 21. The gear can be quenched to improve the surface hardness, improve its wear resistance and load-bearing capacity. When the driving motor drives the driving gear to rotate, the meshing action of the gear and the rack 211 enables the lifting refrigeration plate 21 to move smoothly in the vertical direction.

[0116] In this embodiment, when the position of the lifting refrigeration plate 21 needs to be adjusted, the controller can control the drive motor to start. For example, if it is necessary to rise, the controller outputs a signal to make the drive motor rotate forward, and the drive gear rotates clockwise, and drives the lifting refrigeration plate 21 to rise vertically through the engagement with the rack 211. During the rising process, the position of the lifting refrigeration plate 21 can be monitored in real time by the position sensor, and the data is fed back to the controller. When the lifting refrigeration plate 21 rises to the target position, the controller stops the drive motor according to the position sensor signal to complete the position adjustment. If a fault occurs during the adjustment process, such as motor jamming, gear slippage, etc., the controller can immediately stop the motor operation, and send a fault alarm signal, and display the fault information on the display screen of the refrigeration equipment, such as "drive device 22 fault, please check and repair", so that the user can handle it in time.

[0117] This embodiment can achieve precise vertical position adjustment of the lifting refrigeration plate 21 through the cooperation of the driving motor, the driving gear and the rack 211, so as to better meet different refrigeration needs.

[0118] In addition, a guide structure 111 may be provided at the insertion port of the refrigeration plate placement groove 11 to guide the lifting refrigeration plate 21 to be inserted into the refrigeration plate placement groove 11. The guide structure 111 may be a V-shaped extrusion structure. This structure can provide preliminary guidance and positioning for the lifting refrigeration plate 21 when it is inserted, ensuring that it is correctly inserted into the refrigeration plate placement groove 11. Specifically, when the lifting refrigeration plate 21 is close to the insertion port, the two side walls 32 of the V-shaped extrusion structure may contact the edge of the lifting refrigeration plate 21, and through a slight extrusion effect, the lifting refrigeration plate 21 automatically adjusts its position to align with the central axis of the refrigeration plate placement groove 11.

[0119] It should be noted that the guide structure 111 may be other structures in addition to the above-mentioned structures, and there is no limitation on this. For example, inside the refrigeration plate mounting groove 11, a wedge-shaped structure may be provided along the direction extending inward from the insertion port as the guide structure 111. The wedge angle of the wedge-shaped structure may be 30 degrees, and the height gradually increases from 2 mm at the insertion port to 5 mm inside. Its material may be the same as the groove wall of the refrigeration plate mounting groove 11, for example, both are made of aluminum alloy, have good thermal conductivity and a smooth surface, which facilitates the sliding of the lifting refrigeration plate 21. During the lifting process of the lifting refrigeration plate 21, the wedge-shaped structure can further accurately guide it, so that the lifting refrigeration plate 21 and the first cold conduction plate 121 in the interlayer device 1 are finally tightly fitted, ensuring efficient transfer of cold.

[0120] The sandwich device 1 may include a positioning structure, and the positioning structure is used to align the insertion port of the positioning refrigeration plate placement groove 11 with the lifting refrigeration plate 21. The positioning structure can cooperate with the positioning matching structure on the refrigerated box 3 (not shown in the figure), for example, the positioning structure may include a first positioning protrusion 14, and the positioning matching structure may be a first positioning groove that cooperates with the above-mentioned first positioning protrusion 14, and the positioning of the sandwich device 1 is achieved by the first positioning protrusion 14 being inserted into the first positioning groove, so as to better ensure that the sandwich device 1 is accurately installed to the required position, and the accuracy can be controlled within 0.2mm, so as to better ensure that the insertion port of the refrigeration plate placement groove 11 is aligned with the lifting refrigeration plate 21, and ensure that the groove wall of the refrigeration plate placement groove 11 is in correct contact with the side of the lifting refrigeration plate 21, thereby ensuring that the lifting refrigeration plate 21 is smoothly inserted into the refrigeration plate placement groove 11.

[0121] Among them, the positioning structure may include a second positioning protrusion (not shown in the figure), and the refrigeration device 2 is provided with a second positioning groove (not shown in the figure) cooperating with the second positioning protrusion. The second positioning protrusion is inserted into the second positioning groove to realize the mutual positioning of the interlayer device 1 and the refrigeration device 2, so as to better ensure that the insertion port of the refrigeration plate mounting groove 11 is aligned with the lifting refrigeration plate 21, and then ensure that the lifting refrigeration plate 21 is smoothly inserted into the refrigeration plate mounting groove 11.

[0122] The refrigeration device 2 may further include a cooling member 23 and at least one semiconductor cooling member 24, and the cooling member 23 may be located between the semiconductor cooling member 24 and the lifting cooling plate 21. The first side of the cooling member 23 is attached to the cold end of at least one semiconductor cooling member 24, and the second side of the cooling member 23 is attached to the lifting cooling plate 21, and the first side and the second side are two opposite sides of the cooling member 23.

[0123] For example, the cooling member 23 may be a cooling aluminum plate, and the semiconductor cooling member 24 may be a semiconductor cooling plate. The first side of the cooling aluminum plate is attached to the cold end of the semiconductor cooling plate, and the second side of the cooling aluminum plate is attached to the lifting cooling plate 21. In this way, the cooling aluminum plate can transfer the cooling energy of the semiconductor cooling plate to the lifting cooling plate 21.

[0124] It should be noted that the cooling element 23 and the semiconductor cooling element 24 may be other structures besides structures, and this is not limited.

[0125] In addition, when the refrigeration device 2 includes at least two semiconductor refrigeration elements 24 (ie, more than one semiconductor refrigeration element 24), the at least two semiconductor refrigeration elements 24 may share the same cooling element 23 to reduce the arrangement of the cooling element 23 and reduce the cost.

[0126] Among them, when the refrigeration device 2 includes at least two semiconductor refrigeration elements 24, the controller of the refrigeration equipment can control the number of semiconductor refrigeration elements 24 in working state in the refrigeration assembly based on the target temperature of the refrigeration equipment and / or the ambient temperature of the refrigeration equipment, thereby achieving accurate control of the refrigeration effect.

[0127] For example, when the target temperature is set to 15°C-18°C, or the ambient temperature is low (e.g., below 20°C), it indicates that the cooling demand of the compartment of the refrigerated box 3 is small. At this time, any semiconductor refrigeration element 24 in the refrigeration assembly can be controlled to be in a working state (i.e., a refrigeration state), while other semiconductor refrigeration elements 24 can be controlled to be in a non-refrigeration state, thereby reducing the cooling capacity generated by the refrigeration device 2, thereby reducing the cooling capacity transferred to the refrigerated box 3. That is, in this embodiment, when other conditions remain unchanged, the target temperature is positively correlated with the number of semiconductor refrigeration elements 24 put into working state, and the ambient temperature is also positively correlated with the number of semiconductor refrigeration elements 24 put into working state.

[0128] It should be noted that, in addition to controlling the number of semiconductor refrigeration components 24 in operation based on the target temperature and / or the ambient temperature, it may also be controlled in other ways, which are not limited thereto.

[0129] The refrigeration device 2 may include at least one heat sink 25, and at least one heat sink 25 corresponds to at least one semiconductor refrigeration element 24 one by one, and among the heat sinks 25 and semiconductor refrigeration elements 24 corresponding to each other, the heat sink 25 is attached to the hot end of the semiconductor refrigeration element 24. In other words, each semiconductor refrigeration element 24 is configured with a corresponding heat sink 25. For example, if two semiconductor refrigeration elements 24 are provided, two heat sinks 25 need to be provided, and are attached to the hot ends of the corresponding semiconductor refrigeration elements 24, respectively, to better dissipate heat, thereby ensuring the refrigeration effect.

[0130] In some embodiments,

[0131] The heat sink 25 may include a hot end heat sink aluminum 251 and a heat sink fan 252. The cold end of the semiconductor refrigeration sheet may be attached to the hot end heat sink aluminum 251. A heat sink fan 252 is provided on the side of the hot end heat sink aluminum 251 away from the semiconductor refrigeration sheet. The hot end heat sink aluminum 251 dissipates heat through the heat sink fan 252, thereby realizing the refrigeration of the semiconductor refrigeration sheet. Since the refrigeration device 2 is not arranged on the rear wall 31 of the refrigerated box 3, it will not affect the volume of the refrigerated box 3. Therefore, the heat sink fan 252 may not be limited by space, so that a fan with better heat dissipation efficiency, low speed and low noise can be selected to improve the refrigeration effect. In addition, the semiconductor refrigeration sheet can also be selected with a larger specification, such as a 6A or 8A refrigeration sheet, which has a larger cooling capacity and a better cooling effect. In this case, the temperature of the lifting refrigeration plate 21 can quickly reach -15°C or lower, and then be transferred to the cooling water of the water storage tank 123 through the first refrigeration plate. The overall size of the water storage tank 123 is relatively thin and the contact area is large, which will quickly cool the cooling water in the water storage tank to the required temperature, such as 0°C-1°C. The cooling water is transferred to the rear wall 31 of the refrigerated box 3 through the second cooling plate, thereby cooling the compartment. At the same time, the spray device 34 can spray low-temperature water mist into the compartment, which can quickly cool down the compartment to the required temperature.

[0132] The refrigeration device 2 may further include a first insulation layer 26. The material of the first insulation layer 26 and the second insulation layer 13 may be the same or different, and there is no limitation on this. For example, the first insulation layer 26 may be an insulation foam layer. The first insulation layer 26 can form a reliable insulation barrier on the cold end side of the refrigeration device 2, reduce the loss of cold to the external environment, thereby reducing the energy consumption of the refrigeration equipment and improving the refrigeration efficiency.

[0133] There is a cold cavity between the first insulation layer 26 and the cold conducting member 23 for accommodating the lifting refrigeration plate 21. The design of the cold cavity provides a relatively closed space for the refrigeration process, which is conducive to the gathering and uniform distribution of cold energy. A first fan 27 is arranged in the cold cavity. The first fan 27 adopts a small axial flow fan. The first fan 27 is arranged in the cold cavity. The first fan 27 is used to drive the gas flow in the cold cavity, thereby ensuring the uniform distribution of cold energy.

[0134] The cooling assembly of this embodiment enables the refrigeration equipment to achieve precise temperature control with a small temperature fluctuation range through the coordinated cooperation of the semiconductor refrigeration component 24, the cooling component 23, the heat dissipation component 25, the first insulation layer 26 and the first fan 27, so as to improve the user experience.

[0135] When the refrigeration device in the present disclosure is a beauty refrigerator, the refrigerated box 3 is the beauty box of the beauty refrigerator. In the beauty refrigerator, the beauty box and the interlayer device 1 are detachable and separated, and an external refrigeration device 2 is used for refrigeration, which abandons the encroachment of the internal space of the beauty box by the traditional refrigeration structure. The refrigeration components of traditional beauty refrigerators are often integrated inside or on the back side of the box, occupying a considerable part of the precious space, resulting in a significant reduction in the actual space that can be used to store items. The design of the present disclosure allows the internal space of the beauty box to be completely retained, and only cooperates with the external refrigeration component when refrigeration is needed, which greatly improves the actual space utilization rate of the beauty refrigerator and allows users to store more types and quantities of items.

[0136] In addition, the present disclosure adopts a unique auxiliary refrigeration and cooling method, low-temperature spray, which can quickly cool down the hot air in the box. Compared with the traditional single conduction cooling method, spray cooling is not limited by contact with the surface of objects, and can penetrate into every corner of the box, so that the temperature in the box drops evenly, achieving an all-round cooling effect. Spray cooling and traditional conduction cooling are carried out simultaneously, and the two cooperate with each other and complement each other. Through the close cooperation of the interlayer device 1 and the refrigeration component, the conduction cooling stably transfers the cold to various parts of the beauty box, providing a low-temperature basis for spray cooling, so that the water droplets formed by the spray can evaporate and absorb heat in a lower temperature environment, further enhancing the cooling effect. Spray cooling makes up for the relatively slow conduction cooling speed, especially in quickly reducing the overall temperature in the box. This synergistic effect greatly accelerates the cooling speed of refrigeration equipment such as beauty refrigerators, and can achieve an ideal low-temperature storage environment in a shorter time, providing better preservation conditions for items.

[0137] In addition, the present disclosure can control the cooling speed and cooling effect by using the lifting distance of the lifting refrigeration plate 21 and the number of semiconductor refrigeration components 24 put into operation. This innovative design provides users with accurate and flexible cooling adjustment methods. This ability to flexibly adjust cooling parameters according to actual needs not only improves the intelligence of the refrigeration system, but also effectively saves energy and extends the service life of the refrigeration components, while also better meeting the personalized requirements of different items for storage temperature.

[0138] The convenient disassembly and separation characteristics of the beauty refrigerator have many advantages in actual use. When the beauty box needs to be cleaned, maintained or the internal layout needs to be changed, the user can easily separate the beauty box from the sandwich device 1 and the refrigeration component. The operation is simple and convenient, and no professional tools or complicated disassembly steps are required. For example, when the inside of the beauty box is stained and needs to be thoroughly cleaned, it is only necessary to disassemble the components and clean them separately, which greatly improves the convenience and thoroughness of cleaning. In addition, when the beauty box needs to be moved, the refrigeration device 2 and the sandwich device 1 can be disassembled, and the beauty box and the sandwich device 1 can be moved separately or even only the beauty box can be moved. There is no need to move the heavier refrigeration device 2, which significantly reduces the weight of the moved part, making the movement of the beauty box easier and more convenient. Whether it is changing the placement position at home or carrying the beauty box in scenes such as traveling or business trips, it can provide great convenience for users and improve the flexibility and applicability of the beauty box.
