Beauty refrigerator
[0001] Cross-reference to related applications
[0002] This application is based on and claims priority to Chinese Patent Application No. 202411899029.8, filed on December 23, 2024, the disclosure of which is incorporated herein by reference in its entirety. Technical Field
[0003] This disclosure relates to the field of refrigeration equipment technology, and in particular to a cosmetic refrigerator. Background Technology
[0004] Beauty refrigerators are designed specifically for storing skincare and cosmetic products, suitable for home or professional dressing rooms. Currently, most beauty refrigerators on the market use semiconductor direct cooling technology, which easily leads to condensation on the cooling metal parts or the refrigerator's side walls, failing to meet the dryness requirements of cosmetics storage. Furthermore, due to structural limitations, it's difficult to collect or drain this moisture, increasing the refrigerator's maintenance complexity.
[0005] It should be noted that the information disclosed in the background section of this disclosure is intended only to enhance the understanding of the overall background of this disclosure, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention
[0006] This disclosure provides a beauty refrigerator with an optimized structure to achieve effective and convenient treatment of condensate.
[0007] According to one aspect of this disclosure, a beauty refrigerator is provided, comprising:
[0008] The box has a storage compartment inside for storing items;
[0009] A refrigeration unit, located outside the storage cavity, is configured to generate cooling capacity;
[0010] A cooling structure, configured to transfer cold energy to a storage cavity, includes a cooling plate and a cooling block. The cooling plate is disposed on the first cavity wall of the storage cavity, and the cooling block is disposed between the cold end of the refrigeration device and the cooling plate.
[0011] A water treatment device includes a first water collection box and a drainage structure. The first water collection box is disposed in the storage cavity and located below the cooling plate, and the positions of the first water collection box and the cooling block are corresponding. The first water collection box is configured to collect condensate on the cooling plate, and the drainage structure is configured to discharge the condensate collected by the first water collection box to the outside of the storage cavity.
[0012] In some embodiments, the first water collection box has an opening, and the cooling plate includes a cooling plate body and a first flow guide portion connected to one end of the cooling plate body near the first water collection box. The first flow guide portion bends away from the first cavity wall relative to the cooling plate body and extends to the opening of the first water collection box.
[0013] In some embodiments, on the side of the cold-conducting plate away from the first cavity wall, the connection between the cold-conducting plate body and the first flow guide has a first included angle α, the size of which is 120 to 150 degrees.
[0014] In some embodiments, the cold-conducting plate body includes a first cold-conducting plate and a second cold-conducting plate connected to the first cold-conducting plate.
[0015] In the vertical direction, the second cold guide plate is located between the first cold guide plate and the first water collection box.
[0016] In the horizontal direction, the width of the second cold-conducting plate is smaller than the width of the first cold-conducting plate, and the second cold-conducting plate is positioned corresponding to the first water collection box.
[0017] In some embodiments, the first cooling plate has a second flow guide portion at one end near the second cooling plate, which bends toward the first cavity wall, and the second flow guide portion is connected to the second cooling plate.
[0018] In some embodiments, on the side of the cooling plate away from the first cavity wall, the connection between the second flow guide and the second cooling plate has a second included angle β, the size of which is 120 to 150 degrees.
[0019] In some embodiments, the extension direction of the second guide portion has a third included angle γ with the horizontal direction, so that the height of the end of the second guide portion near the first water collection box in the vertical direction is less than the height of the end of the second guide portion away from the first water collection box.
[0020] In some embodiments, the third included angle γ is 10 to 30 degrees.
[0021] In some embodiments, the water treatment device further includes a second water collection box disposed outside the storage cavity, with both ends of the drainage structure disposed in the first water collection box and the second water collection box respectively, so as to discharge the condensate in the first water collection box to the second water collection box.
[0022] The drainage structure includes a moisture-absorbing component with a moisture-absorbing function. The two ends of the moisture-absorbing component are respectively located in the first water collection box and the second water collection box, so as to draw out the condensate in the first water collection box to the second water collection box through the moisture-absorbing component.
[0023] In some embodiments, the beauty refrigerator further includes heat dissipation fins disposed close to the hot end of the refrigeration unit, and the drainage structure includes a moisture-absorbing rope and a moisture-absorbing cloth. The moisture-absorbing cloth is attached to the heat dissipation fins, one end of the moisture-absorbing rope is disposed in a first water collection box, and the other end is connected to the moisture-absorbing cloth. The lower end of the moisture-absorbing cloth is located in a second water collection box.
[0024] In some embodiments, the beauty refrigerator also includes a fan configured to deliver airflow to the absorbent cloth and / or heat dissipation fins.
[0025] In some embodiments, the beauty refrigerator further includes a flow guiding structure installed on a second cavity wall of the storage cavity, the second cavity wall being connected to the first cavity wall, the flow guiding structure being configured to guide condensate formed on its surface to a cold plate.
[0026] In some embodiments, the flow guiding structure includes a plurality of water collection troughs extending to the side of the cooling plate away from the first cavity wall, wherein, in the vertical direction, the height of the end of the water collection trough near the first cavity wall is less than the height of the end of the water collection trough away from the first cavity wall.
[0027] In some embodiments, the housing is inclined relative to the vertical direction so that condensate on the flow guiding structure flows from the side away from the first cavity wall to the side closer to the first cavity wall.
[0028] In some embodiments, the bottom surface of the box has an inclination angle δ with respect to the horizontal plane, and the inclination angle δ is 3 to 5 degrees.
[0029] In some embodiments, the cooling device is a semiconductor cooling module.
[0030] Based on the above technical solution, this disclosure includes a cold-conducting plate inside the storage cavity, which effectively transfers cooling energy to the cavity. During this cooling process, condensate generated on the cold-conducting plate flows downwards into the storage cavity under gravity, allowing the first water collection box located below the cold-conducting plate to collect the condensate promptly. Furthermore, a drainage structure ensures that the condensate collected in the first water collection box is drained from the storage cavity, preventing condensate from accumulating and spreading within the cavity and affecting the quality of the stored items.

[0040] The technical solutions in the embodiments of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0041] In the description of this disclosure, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure.
[0042] Referring to Figure 1, in some embodiments of the beauty refrigerator provided in this disclosure, the beauty refrigerator includes a cabinet 1, a refrigeration device 2, a cold-conducting structure, and a water treatment device. The cabinet 1 has a storage cavity 11 for storing items. The refrigeration device 2 is disposed outside the storage cavity 11 and is configured to generate cooling. The cold-conducting structure is configured to transfer cooling to the storage cavity 11, and includes a cold-conducting plate 3 and a cold-conducting block 10. Referring to Figure 5, the cold-conducting plate 3 is disposed on the first cavity wall 111 of the storage cavity 11, and the cold-conducting block 10 is disposed between the cold end of the refrigeration device 2 and the cold-conducting plate 3. Referring to Figure 2, the water treatment device includes a first water collection box 4 and a drainage structure 5. The first water collection box 4 is disposed in the storage cavity 11 and located below the cooling plate 3. The positions of the first water collection box 4 and the cooling block 10 are corresponding. The first water collection box 4 is configured to collect condensate on the cooling plate 3. The drainage structure 5 is configured to discharge the condensate collected by the first water collection box 4 to the outside of the storage cavity 11.
[0043] Here, the cooling block 10 can transfer the cold energy generated by the cold end of the refrigeration device 2 to the cooling plate 3. The cooling plate 3 is set on the first cavity wall 111 of the storage cavity 11, which can fully transfer the cold energy into the storage cavity 11, so that the cold energy can be fully diffused in the storage cavity 11.
[0044] The positions of the refrigeration unit 2 and the cold-conducting block 10 can be adjusted to accommodate the layout requirements of surrounding components, ensuring effective cold air transfer while improving the overall flexibility of the beauty refrigerator's layout. The shape and specifications of the cold-conducting block 10 can also be adapted. For example, considering the layout of other components in the beauty refrigerator (such as the fan), the refrigeration unit 2 and the cold-conducting block 10 can be offset relative to the cold-conducting plate 3, thus providing suitable installation space for other components.
[0045] During the transfer of cooling energy, condensation occurs on the cooling plate 3. Under the influence of gravity, this condensation flows / drips downwards into the storage cavity 11. The first water collection box 4, located below the cooling plate 3, collects this condensation promptly. Furthermore, the closer the area on the cooling plate 3 is to the cooling block 10, the lower its temperature, and the more condensation occurs in that area. Therefore, by positioning the first water collection box 4 corresponding to the cooling block 10, the condensation on the cooling plate 3 can be effectively collected, preventing the concentrated condensation from affecting the items stored in the storage cavity 11.
[0046] Taking the direction shown in Figure 1 as an example, the refrigeration device 2 and the cooling block 10 are located behind the cooling plate 3 (not shown in the figure) and are positioned biased towards the right side of the cooling plate 3. Thus, in the embodiment shown in Figure 1, the first water collection box 4 is positioned corresponding to the cooling block 10, that is, it is located below the cooling plate 3 and biased towards its right side, so that the first water collection box 4 can effectively collect the condensate generated at the corresponding positions of the cooling plate 3 and the cooling block 10.
[0047] The cold-conducting plate 3 and the cold-conducting block 10 can be made of materials with high heat transfer efficiency to achieve efficient transfer of cooling capacity. For example, copper or aluminum alloy can be used. In large-scale production, considering both production cost and heat transfer performance, aluminum alloy can be selected.
[0048] In addition, the drainage structure 5 is set up to discharge the condensate collected by the first water collection box 4 out of the storage cavity 11 in a timely manner, which can prevent the condensate from accumulating and spreading in the storage cavity 11 and affecting the quality of the items stored therein.
[0049] Referring to Figure 2, in some embodiments, the first water collection box 4 has an opening, and the cooling plate 3 includes a cooling plate body 31 and a first flow guide 32 connected to the cooling plate body 31 near one end of the first water collection box 4. The first flow guide 32 bends away from the first cavity wall 111 relative to the cooling plate body 31 and extends to the opening of the first water collection box 4.
[0050] The first guide section 32 can guide the flow direction of the condensate, allowing it to flow smoothly into the first water collection box 4. By forming a bend between the first guide section 32 and the cooling plate body 31, the falling condensate can be collected here, thus flowing into the first water collection box 4 more concentratedly and efficiently.
[0051] In addition, by reasonably setting parameters such as the size, bending direction, and bending angle of the first guide section 32, the cold guide plate body 31 and the first water collection box 4 can be arranged adaptively according to the layout requirements inside different storage cavities 11, thereby improving the design flexibility of the beauty refrigerator.
[0052] Referring to Figure 2, in some embodiments, on the side of the cooling plate 3 away from the first cavity wall 111, the connection between the cooling plate body 31 and the first flow guide 32 has a first included angle α, the size of which is 120 to 150 degrees.
[0053] The first included angle α is 120 to 150 degrees, which is conducive to the effective and timely guidance and collection of condensate.
[0054] In a specific example, the first included angle α is 140 degrees.
[0055] When designing the interior of a beauty refrigerator, the structure of the cooling plate 3 can be adapted to the partitioning requirements of its internal storage cavity 11.
[0056] Referring to Figure 3, in some embodiments, the cold-conducting plate body 31 includes a first cold-conducting plate 311 and a second cold-conducting plate 312 connected to the first cold-conducting plate 311. In the vertical direction, the second cold-conducting plate 312 is located between the first cold-conducting plate 311 and the first water collection box 4. In the horizontal direction, the width of the second cold-conducting plate 312 is smaller than the width of the first cold-conducting plate 311, and the second cold-conducting plate 312 is positioned correspondingly to the first water collection box 4.
[0057] By designing the cooling plate body 31 to include a first cooling plate 311 and a second cooling plate 312, different partitions can be formed within the storage cavity 11 by adjusting the dimensions and shapes of the first and second cooling plates 311 and 312. Here, by setting the width of the second cooling plate 312 to be smaller than the width of the first cooling plate 311, modules such as sterilization, temperature sensing, and fragrance can be arranged in the area adjacent to the second cooling plate 312 on the first cavity wall 111 to meet diverse user needs. Alternatively, a cooling fan can be installed in this area to improve the airflow circulation efficiency within the storage cavity 11 and enhance the cooling effect.
[0058] The position of the second cold-conducting plate 312 in the width direction of the first cold-conducting plate 311 can be set according to the layout of the refrigeration device 2. Taking Figure 1 as an example, the refrigeration device 2 and the cold-conducting block 10 are located behind the first cold-conducting plate 311 (not shown in the figure) and are arranged to the right side of the first cold-conducting plate 311. The space on the left side behind the first cold-conducting plate 311 can be used to arrange other components of the beauty refrigerator, such as a fan.
[0059] In this situation, referring to Figure 3, less condensate is generated on the left side surface of the first cooling plate 311, while more condensate is generated on the right side surface. Correspondingly, a second cooling plate 312 can be connected to the right side of the first cooling plate 311 in the width direction to ensure that the condensate generated on the right side surface is effectively introduced into the first water collection box 4. The condensate generated on the left side surface of the first cooling plate 311 is less and less likely to accumulate. Furthermore, due to the surface tension of the droplets, the condensate is usually able to remain adsorbed on the first cooling plate 311 and is less likely to drip directly to the bottom of the storage cavity 11. The method for handling this condensate will be described later.
[0060] Referring to Figures 3 and 4, in some embodiments, the first cooling plate 311 has a second flow guide 311a that bends toward the first cavity wall 111 at one end near the second cooling plate 312, and the second flow guide 311a is connected to the second cooling plate 312.
[0061] A bent second guide section 311a is provided in the first cooling plate 311. The bent structure introduces additional resistance in the flow path of the condensate, which helps to slow down the flow rate of the condensate. Especially when a large amount of condensate forms on the first cooling plate 311, the resistance brought by the bent structure prevents the condensate from sliding down rapidly. Instead, it flows more slowly under the guidance of the cooling plate body 31, avoiding splashing or overflow caused by excessive water flow speed.
[0062] In embodiments where the widths of the first cooling plate 311 and the second cooling plate 312 are different, slowing down the water flow helps to prevent condensate from dripping directly from the edge of the first cooling plate 311, which is longer than the second cooling plate 312, and thus failing to be collected by the first water collection box 4.
[0063] Furthermore, taking Figure 1 as an example, the first cold-conducting plate 311 and the second cold-conducting plate 312 are disposed on the first cavity wall 111 of the refrigerator door of the beauty refrigerator, which is opposite to the storage cavity 11. Compared with the first cold-conducting plate 311 and the second cold-conducting plate 312 being a flat plate structure extending from the upper part to the lower part of the storage cavity 11, a second guide portion 311a that bends toward the first cavity wall 111 is provided at one end of the first cold-conducting plate 311 near the second cold-conducting plate 312. This allows the depth of the lower space of the storage cavity 11 (relative to the refrigerator door) to be increased, thereby increasing the volume of the storage cavity 11 and improving the capacity of the beauty refrigerator.
[0064] As an example, the space at the bottom of the storage cavity 11 can be equipped with drawers for storage, thereby facilitating the formation of different storage partitions within the storage cavity 11 and realizing a personalized layout of the storage cavity 11.
[0065] The degree of bending of the second guide section 311a can be adjusted according to the surface structure of the first cavity wall 111. For example, a suitable bending angle can be used so that the first cold conduction plate 311 can fit in close contact with the surface of the first cavity wall 111, ensuring sufficient cold transfer efficiency. Alternatively, the bending angle can be selected based on its deceleration and guiding effect on condensate, so that condensate can flow smoothly into the first water collection box 4.
[0066] Referring to Figure 4, in some embodiments, on the side of the cooling plate 3 away from the first cavity wall 111, the connection between the second flow guide 311a and the second cooling plate 312 has a second included angle β, the size of which is 120 to 150 degrees.
[0067] The second included angle β is 120 to 150 degrees, which is conducive to obtaining a suitable flow velocity for the condensate, and to achieving effective guidance and collection of the condensate.
[0068] In a specific example, the second included angle β is 122 degrees.
[0069] In addition, to facilitate the flow of condensate into the first water collection box 4, the second guide portion 311a can be inclined. Referring specifically to FIG3, in some embodiments, the extension direction of the second guide portion 311a has a third included angle γ with the horizontal direction, so that the height of the end of the second guide portion 311a near the first water collection box 4 in the vertical direction is less than the height of the end of the second guide portion 311a away from the first water collection box 4.
[0070] Here, guided by the inclined second guide section 311a, the condensate can flow to the first water collection box 4 more quickly, improving the condensate collection efficiency and reducing evaporation during the condensate flow process, further ensuring that the storage cavity 11 has suitable humidity.
[0071] In an embodiment where the amount of condensate generated on the left and right sides of the first cooling plate 311 is inconsistent, as mentioned above, a second guide section 311a inclined to the right can be provided to guide a small amount of condensate generated on the left side of the first cooling plate 311 from the left side to the right side of the second guide section 311a, and further collect it with the condensate generated on the right side of the first cooling plate 311, and then flow into the first water collection box 4.
[0072] The inclination of the second guide section 311a can be adjusted according to actual design requirements.
[0073] In some embodiments, the third included angle γ is 10 to 30 degrees.
[0074] The third included angle γ is between 10 and 30 degrees, which helps the condensate to flow to the first water collection box 4 at a suitable speed, thereby improving the condensate collection efficiency.
[0075] Referring to Figure 2, in some embodiments, the water treatment device further includes a second water collection box 6 disposed outside the storage cavity 11, and the two ends of the drainage structure 5 are respectively disposed in the first water collection box 4 and the second water collection box 6, so as to discharge the condensate in the first water collection box 4 to the second water collection box 6.
[0076] The drainage structure can promptly guide the condensate in the first water collection box 4 to the second water collection box 6 located outside the storage cavity 11. This reduces the evaporation / diffusion of the collected condensate in the storage cavity 11, effectively ensuring the dryness of the internal environment of the storage cavity 11. It also avoids the inconvenience of users having to frequently clean the water in the first water collection box 4, thus improving the user experience of the beauty refrigerator.
[0077] In some embodiments, the drainage structure 5 includes a moisture-absorbing member with a moisture-absorbing function. The two ends of the moisture-absorbing member are respectively disposed in the first water collection box 4 and the second water collection box 6, so as to absorb the condensate in the first water collection box 4 into the second water collection box 6 through the moisture-absorbing member.
[0078] Compared to related technologies that use drain pipes or drain holes for drainage, which allow external air to enter the storage cavity and affect its humidity and cleanliness, the moisture-absorbing component of this disclosure occupies less space and does not have a pipe / hole structure that allows external air to enter. This effectively prevents external air from entering the storage cavity 11 and improves its airtightness.
[0079] As an example, the absorbent material can be an absorbent rope or absorbent cloth made of absorbent materials such as cotton, nylon, linen, or fiber.
[0080] Referring to Figure 2, in some embodiments, the beauty refrigerator also includes heat dissipation fins 7 disposed close to the hot end of the refrigeration device 2, and the drainage structure 5 includes a moisture-absorbing rope 51 and a moisture-absorbing cloth 52. The moisture-absorbing cloth 52 is attached to the heat dissipation fins 7. One end of the moisture-absorbing rope 51 is disposed in the first water collection box 4, and the other end is connected to the moisture-absorbing cloth 52. The lower end of the moisture-absorbing cloth 52 is located in the second water collection box 6.
[0081] The absorbent rope 51, through the principle of capillary action, gradually absorbs the condensate in the first water collection box 4 and transports it to the absorbent cloth 52. The absorbent cloth 52 has a large surface area, which enables effective evaporation and dissipation of moisture, thereby creating a humidity difference at both ends of the absorbent rope 51. This increases the drainage efficiency of the absorbent rope 51 from inside the storage cavity 11 to outside the storage cavity 11, preventing the condensate in the first water collection box 4 from accumulating and overflowing.
[0082] The heat dissipation fins 7 help the cooling device 2 dissipate heat quickly, improving its operating efficiency. Simultaneously, attaching the absorbent cloth 52 to the heat dissipation fins 7 utilizes the heat dissipated from the hot end of the cooling device 2, allowing the moisture on the absorbent cloth 52 to evaporate quickly. The evaporation of moisture from the absorbent cloth 52 also contributes to the cooling effect of the heat dissipation fins 7.
[0083] Furthermore, under conditions where the operating power of the refrigeration device 2 increases and the amount of condensate inside the storage cavity 11 increases, the temperature of the hot end of the refrigeration device 2 rises, and the heat dissipation of the heat dissipation fins 7 increases. As a result, the rate of moisture evaporation on the absorbent cloth 52 increases, and the drainage efficiency of the absorbent rope 51 also increases. Thus, this disclosure uses the absorbent rope 51, absorbent cloth 52, and heat dissipation fins 7 together to achieve the drainage and treatment of condensate in the storage cavity 11, effectively preventing the accumulation of condensate in the first water collection box 4 under various operating conditions.
[0084] As an example, the absorbent rope 51 is made of polyester fiber, and the absorbent cloth 52 is a composite material of PET and fiber.
[0085] Furthermore, referring to FIG5, in some embodiments, the beauty refrigerator also includes a fan 8 configured to deliver airflow to the moisture-absorbing cloth 52 and / or the heat dissipation fins 7.
[0086] By enhancing the surface convection effect of the absorbent cloth 52 and / or the heat dissipation fins 7 through the fan 8, the evaporation efficiency of moisture can be further improved and the cooling effect of the heat dissipation fins 7 on the hot end of the refrigeration device 2 can be enhanced.
[0087] During the use of the beauty refrigerator, condensation will not only occur on the surface of the cold guide plate 3. Corresponding structures can be installed on other cavity walls of the storage cavity 11 to collect and guide the condensation, which is of great significance for further improving the internal environment of the storage cavity 11.
[0088] Referring to Figure 1, in some embodiments, the beauty refrigerator also includes a flow guiding structure 9 installed on a second cavity wall 112 of the storage cavity 11, the second cavity wall 112 being connected to the first cavity wall 111, and the flow guiding structure 9 being configured to guide condensate formed on its surface to a cold guiding plate 3.
[0089] The flow guiding structure 9 directs the condensate onto the cooling plate 3, allowing it to flow along an existing flow path (e.g., a path guided by the flow guiding structure on the surface of the cooling plate 3) towards the first water collection box 4. This method simplifies the condensate treatment process and avoids the complexity of multi-point decentralized treatment.
[0090] In addition to the second cavity wall 112, corresponding flow guiding structures can also be provided on other cavity walls in the storage cavity 11 that will generate condensate.
[0091] In some embodiments, the flow guiding structure 9 includes a plurality of water collection troughs 91 extending to the side of the cooling plate 3 opposite to the first cavity wall 111. In the vertical direction, the height of the end of the water collection trough 91 near the first cavity wall 111 is less than the height of the end of the water collection trough 91 away from the first cavity wall 111.
[0092] The trough-shaped structure of the water collection tank 91 can effectively collect condensate. Furthermore, the two ends of the water collection tank 91 are at different heights, so under the action of gravity, the condensate can naturally flow downwards along the water collection tank 91 until it flows to the cooling plate 3.
[0093] As an example, multiple water collection tanks 91 can be arranged in a row, and the cross-sectional structure of the water collection tanks 91 formed therefrom can be seen in Figure 6.
[0094] Additionally, by tilting the entire cabinet 1, it is possible to easily collect the condensate inside. Furthermore, this slight tilt also makes it easier for users to access items in the beauty refrigerator, enhancing the user experience.
[0095] The existing beauty refrigerator is being modified by tilting the cabinet 1, which allows for easy tilting of the cabinet 1 and all its internal components. By controlling the tilting direction and angle of the cabinet 1, the condensate in the storage cavity 11 can be directed to a preset collection location.
[0096] Referring to Figure 7, in some embodiments, the housing 1 is inclined relative to the vertical direction so that the condensate on the guide structure 9 flows from the side away from the first cavity wall 111 to the side closer to the first cavity wall 111. This allows the condensate on the guide structure 9 to flow centrally to the cooling plate 3 and then into the first water collection box 4, facilitating centralized collection and treatment of the condensate.
[0097] Referring to Figure 7, in some embodiments where the box is set to be inclined, the bottom surface of the box 1 has an inclination angle δ with respect to the horizontal plane, and the inclination angle δ is 3 to 5 degrees.
[0098] The tilt angle δ is 3 to 5 degrees, which is conducive to achieving a good concentration of condensate while ensuring the overall stability of the beauty refrigerator.
[0099] It should be noted that, in order to achieve centralized collection of condensate, it is not necessary to tilt the entire box 1 as shown in the above embodiment. Instead, only the components in the storage cavity 11 that generate condensate can be tilted. In actual design, factors such as design cost and change costs (e.g., changes in production costs due to structural modifications) can be comprehensively considered.
[0100] In some embodiments provided in this disclosure, the refrigeration device 2 of the beauty refrigerator is a semiconductor refrigeration module.
[0101] Semiconductor refrigeration modules achieve refrigeration based on the thermoelectric effect of semiconductors. They feature high reliability, low noise / vibration, fast temperature control response, and easy integration, making them particularly suitable for small products with well-defined functions and intended for home use, such as beauty refrigerators.
[0102] Of course, as the usage scenarios of beauty refrigerators change and evolve, the refrigeration unit 2 can also adopt other forms of refrigeration modules, such as compression refrigeration and absorption refrigeration, to meet different user needs.
[0103] Please refer to Figures 1 to 7 below for a specific embodiment of the beauty refrigerator disclosed herein:
[0104] In this embodiment, the beauty refrigerator includes a cabinet 1, a refrigeration device 2, a cooling structure, a water treatment device, heat dissipation fins 7, a fan 8, and a flow guiding structure 9.
[0105] As shown in Figures 1, 2, and 5, the cabinet 1 includes an outer shell 101 and an inner liner 102, the interior of which forms a storage cavity 11 for storing items. A refrigeration device 2 is disposed between the outer shell 101 and the inner liner 102, and is configured to generate cooling. In this embodiment, the refrigeration device 2 is a semiconductor refrigeration module. Its end near the storage cavity 11 is the cold end, and its end away from the storage cavity 11 is the hot end. A cooling-conducting structure is configured to transfer the cooling generated by the refrigeration device 2 into the storage cavity 11. The cooling-conducting structure includes a cooling-conducting block 10 and a cooling-conducting plate 3. The cooling-conducting plate 3 is disposed on the first cavity wall 111 of the storage cavity 11, and the cooling-conducting block 10 is disposed between the cold end of the refrigeration device 2 and the cooling-conducting plate 3. In this embodiment, the refrigerator door side of the beauty refrigerator is considered the front side. The first cavity wall 111 is the rear cavity wall of the storage cavity 11. The refrigeration unit 2, the cooling structure, the water treatment device, the heat dissipation fins 7, and the fan 8 are all located at the rear of the beauty refrigerator.
[0106] As shown in Figure 2, the water treatment device includes a first water collection box 4, a drainage structure 5, and a second water collection box 6. The first water collection box 4 is located inside the storage cavity 11 and below the cooling plate 3, and is used to collect condensate on the cooling plate 3. The second water collection box 6 is located outside the storage cavity 11.
[0107] As shown in Figure 5, the heat dissipation fins 7 are positioned close to the hot end of the refrigeration device 2, and the fan 8 is positioned near the heat dissipation fins 7 to deliver air to the heat dissipation fins 7.
[0108] As shown in Figure 2, the drainage structure 5 includes a moisture-absorbing rope 51 and a moisture-absorbing cloth 52. The moisture-absorbing cloth 52 is attached to the heat dissipation fins 7. One end of the moisture-absorbing rope 51 is located in the first water collection box 4, and the other end is connected to the moisture-absorbing cloth 52. The lower end of the moisture-absorbing cloth 52 is located in the second water collection box 6.
[0109] As shown in Figure 2, the cooling plate 3 includes a cooling plate body 31 and a first guide portion 32 connected to the end of the cooling plate body 31 near the first water collection box 4. The first guide portion 32 bends away from the first cavity wall 111 relative to the cooling plate body 31 and extends to the opening of the first water collection box 4.
[0110] Additionally, as shown in Figures 1 and 6, a flow guiding structure 9 is installed on the second cavity wall 112 of the storage cavity 11 to collect a small amount of condensate generated on the second cavity wall 112. The flow guiding structure 9 includes multiple water collection grooves 91 extending to the surface of the cooling plate 3. In this embodiment, the second cavity wall 112 is the side wall of the storage cavity 11.
[0111] In this embodiment, the entire housing 1 is tilted backward at an angle δ (as shown in Figure 7), so that the condensate in the water collection tank 91 can flow along the direction of the tank to the cooling plate 3, and then further to the first water collection box 4, thereby collecting the condensate on the second cavity wall 112. In this embodiment, the value of δ is 3 degrees.
[0112] Referring again to Figures 3 and 4, the cooling plate body 31 includes a first cooling plate 311 and a second cooling plate 312 connected to the first cooling plate 311. The end of the first cooling plate 311 near the second cooling plate 312 has a second flow guide portion 311a that bends towards the first cavity wall 111, and the second flow guide portion 311a is connected to the second cooling plate 312. Vertically, the second cooling plate 312 is located between the first cooling plate 311 and the first water collection box 4. Horizontally, the width of the second cooling plate 312 is smaller than the width of the first cooling plate 311, and the positions of the second cooling plate 312 and the first water collection box 4 correspond to each other. On the side of the cooling plate 3 facing away from the first cavity wall 111, the connection between the cooling plate body 31 and the first guide portion 32 has a first included angle α, and the connection between the second guide portion 311a and the second cooling plate 312 has a second included angle β. The sizes of the first included angle α and the second included angle β can both be set within the range of 120 to 150 degrees. In this embodiment, the cooling plate 3 has three bends (forming two bend structures) along the path of condensate flow. Through the two bend structures of the first guide portion 32 and the second guide portion 311a, the condensate is guided, allowing the condensate on the cooling plate 3 to flow smoothly into the first water collection box 4 below.
[0113] As shown in Figure 3, the second guide section 311a is further tilted so that its extension direction has an angle of 10 to 30 degrees with respect to the horizontal direction. This allows the condensate on the left side of the first cooling plate 311 to flow down along the edge of the second guide section 311a to the right before flowing into the first water collection box 4. This design enables the miniaturization of the first water collection box 4, leaving space nearby for the layout of other functional modules.
[0114] During the operation of the beauty refrigerator, condensation occurs on the cooling plate 3. The condensate is guided by the bending structures at the first guide section 32 and the second guide section 311a into the first water collection box 4. Then, the water is guided by the absorbent rope 51 to the second water collection box 6 and onto the absorbent cloth 52. The absorbent cloth 52 adheres tightly to the heat dissipation fins 7, and the fan 8 accelerates the evaporation of the condensate on the absorbent cloth 52, thus completing the entire drainage process of the storage cavity 11. During this process, the evaporation of condensate can remove some of the heat from the hot end of the refrigeration unit 2, improving the heat dissipation effect of the refrigeration unit 2.
[0115] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can be made to some technical features without departing from the principles of this disclosure, and such modifications and equivalent substitutions should all be covered within the scope of the technical solutions claimed in this disclosure.
