Description

Technical Field

[0001] This application relates to the technical field of water cup refrigeration, and particularly to an efficient refrigeration water cup. Background Art

[0002] As a portable refrigeration device, the refrigeration water cup is widely used in daily life. Most traditional refrigeration water cups use a single thermoelectric cooler (TEC) as the core refrigeration component. The cold end directly contacts the inner wall of the water cup for refrigeration, and the hot end dissipates heat through a heat sink. Although the structure of this solution is simple, the refrigeration efficiency is low, the water production is limited, and it is difficult to meet the demand for rapid refrigeration, so it needs to be improved. Summary of the Invention

[0003] In order to improve the refrigeration efficiency and increase the water production, this application provides an efficient refrigeration water cup.

[0004] An efficient refrigeration water cup provided by this application includes a housing and a water storage box arranged inside the housing. A plurality of thermoelectric coolers are arranged above the water storage box. One side of the refrigeration sheet is provided with a cold end fin, and the other side is provided with a hot end fin. A refrigeration air inlet is arranged on the side wall of the housing near the cold end fin, and a heat dissipation air inlet is opened on the side wall of the housing near the hot end fin. It also includes a diversion assembly, which is used to draw air into the housing through the refrigeration air inlet and discharge it from the housing after sequentially contacting the cold end fin and the thermoelectric cooler; and is also used to draw air into the housing through the heat dissipation air inlet and discharge it from the housing after contacting the hot end fin.

[0005] By adopting the above technical solution, a diversion assembly is set to promote air circulation by means of suction intake, so as to accelerate the entry of air into the housing and contact with the cold end fin or the hot end fin. Refrigeration is achieved by contacting the cold end fin and the refrigeration sheet to form condensed water, and heat dissipation is achieved by contacting the hot end fin, ultimately achieving the effects of improving the refrigeration efficiency and increasing the water production.

[0006] Preferably, the thermoelectric coolers are located above the water storage box and are arranged in sequence along the height direction of the housing. The length direction of the cold end fin is parallel to the height direction of the housing. There are a plurality of cold end fins, and a refrigeration gap for air to pass through is reserved between adjacent cold end fins. The refrigeration air inlet is communicated with the refrigeration gap, and the lowermost thermoelectric cooler is located on the flow path of the air entering the refrigeration gap through the refrigeration air inlet.

[0007] By adopting the above technical solution, the flow direction of the air entering the housing through the refrigerated air inlet is defined, that is: the air enters the refrigeration gap through the refrigerated air inlet and first contacts the bottom semiconductor refrigeration sheet to achieve precooling, and then moves upward along the height direction of the housing under the limiting action of the bottom semiconductor refrigeration sheet, so as to sequentially contact the semiconductor refrigeration sheets located above during the upward movement for heat exchange and cooling, until the water vapor in the air is condensed on the cold end fin, and then falls into the water storage box along the length direction of the cold end fin under its own weight.

[0008] Preferably, the guiding assembly includes a cold end suction fan and a hot end heat dissipation fan; the cold end suction fan and the semiconductor refrigeration sheet divide the interior of the housing into a refrigeration area and a heat dissipation area, the cold end fin is located in the refrigeration area, and the cold end suction fan is located above the top semiconductor refrigeration sheet to suck the air in the refrigeration area into the heat dissipation area; the hot end fin and the hot end heat dissipation fan are both located in the heat dissipation area, the hot end heat dissipation fan sucks the air at the heat dissipation air inlet into the heat dissipation area, and a heat dissipation air outlet communicating with the heat dissipation area is also provided on the side wall of the housing.

[0009] By adopting the above technical solution, it can be known from the above that the cold end suction fan sucks the external air of the housing into the refrigeration area through the refrigerated air inlet to achieve refrigeration, the condensed dry air will be sucked into the heat dissipation area by the cold end suction fan, and mixed with the hot air in the heat dissipation area, and cooperate with the hot end fin to accelerate heat dissipation, so as to realize the recycling of cold energy, improve the energy conservation and environmental protection effect, and finally the mixed gas after heat dissipation through the hot end fin will be discharged from the heat dissipation air outlet.

[0010] Preferably, the length direction of the hot end fin is parallel to the width direction of the housing, and there are several hot end fins, and adjacent hot end fins form a heat dissipation gap, the heat dissipation air outlet is communicated with the heat dissipation gap and is located on the extension line of the length direction of the heat dissipation air.

[0011] By adopting the above technical solution, it can be known from the above that the cold end fin is arranged along the direction parallel to the height direction of the housing, and the hot end fin is arranged along the direction parallel to the width direction of the housing. In this arrangement, the heat dissipation air outlet and the refrigerated air inlet do not interfere with each other, effectively avoiding the situation that the wet air at the refrigerated air inlet is heated.

[0012] Preferably, fasteners are provided between the cold end fin and the refrigeration sheet, and between the hot end fin and the refrigeration sheet, and the fasteners are used to fixedly connect the cold end fin and the refrigeration sheet, and the hot end fin and the refrigeration sheet.

[0013] By adopting the above technical solution, when the thermoelectric cooler is in contact with the cold-end fin and the hot-end fin, due to the roughness of the material surface, there will be gaps, and air is a medium with extremely poor thermal conductivity. The air entering the gaps will greatly affect the heat transfer of the thermoelectric cooler to the cold-end fin and the hot-end fin, resulting in the heat not being taken away as soon as possible, thus affecting the refrigeration effect and even burning out the thermoelectric cooler. And simply relying on the gravity of the fin itself to contact the thermoelectric cooler is completely insufficient. Even with the addition of thermal grease with a high thermal conductivity coefficient, the contact thermal resistance still cannot be avoided. To minimize the reduction in heat transfer efficiency caused by the contact thermal resistance, the present application proposes to set fasteners to strengthen the fastening connection between the cold-end fin and the thermoelectric cooler and between the hot-end fin and the thermoelectric cooler.

[0014] Preferably, a spoiler rod is rotatably connected to the fastener. One end of the spoiler rod is located at the hot-end fin, and the other end is located at the cold-end fin. Spoiler blades are provided on the spoiler rod, and a driving member for driving the spoiler rod to rotate is further provided in the housing.

[0015] By adopting the above technical solution, the driving member drives the spoiler rod and the spoiler blades to rotate, thereby helping the flow guiding assembly to accelerate the air flow speed in the housing.

[0016] Preferably, the driving member includes a pressing rod, a linkage frame, and a linkage gear set; the pressing rod and the linkage frame are respectively slidably connected to the housing, and the linkage frame is located on the sliding path of the pressing rod. A docking surface for contacting the pressing rod is provided on the side wall of the linkage frame. The docking surface is used to make the linkage frame slide under the push of the pressing rod when contacting the pressing rod, and the linkage gear set is used to drive the spoiler rod to rotate when the linkage frame slides.

[0017] By adopting the above technical solution, the setting of the driving member enables the user to contact and press the pressing rod as needed to realize the rotation of the spoiler rod and the spoiler blades, and assist the flow guiding assembly to accelerate the air flow.

[0018] Preferably, an opening and closing assembly is further provided in the housing for opening and closing the refrigerating air inlet, the heat dissipation air inlet, and the heat dissipation air outlet.

[0019] By adopting the above technical solution, when refrigeration is not required, the opening and closing assembly is used to close the refrigerating air inlet, the heat dissipation air inlet, and the heat dissipation air outlet to realize the protection of the refrigerating air inlet, the heat dissipation air inlet, and the heat dissipation air outlet, and reduce the blockage at the refrigerating air inlet, the heat dissipation air inlet, and the heat dissipation air outlet.

[0020] Preferably, the water storage box is rotatably connected to the bottom wall of the housing through a rotating shaft. The opening and closing assembly includes a protective grid, a sliding frame, and a return spring. Side walls of the housing near the refrigerating air inlet, the heat dissipation air inlet, and the heat dissipation air outlet respectively correspond to a protective grid, and the sliding frames are provided in one-to-one correspondence with the protective grids; the sliding frames are slidably connected to the housing for opening and closing the corresponding protective grids during the sliding process. The sliding frames located at the heat dissipation air inlet and the heat dissipation air outlet are respectively connected to the return springs, and the return springs are connected between the housing and the corresponding sliding frames, and the telescopic direction of the return spring is parallel to the sliding direction of the sliding frame; When the return spring is not deformed, the bottoms of the sliding frames located at the heat dissipation air inlet and the heat dissipation air outlet are located on the rotation path of the water storage box relative to the housing. When the sliding frames rotate to directly below the housing, the top of the water storage box pushes the bottoms of the sliding frames located at the heat dissipation air inlet and the heat dissipation air outlet, so that the sliding frames located at the heat dissipation air inlet and the heat dissipation air outlet move upward to open the protective grids at the heat dissipation air inlet and the heat dissipation air outlet, and the return springs are deformed; A docking tooth groove is formed in the bottom wall of the sliding frame at the refrigerating air inlet along its sliding direction. A docking ring is sleeved on the rotating shaft at the rotational connection between the water storage box and the housing. A tooth block for meshing with the docking tooth groove is provided on the docking ring. The tooth block is used for meshing with the docking tooth groove during the sliding process of the water storage box and driving the corresponding sliding frame to slide to open and close the protective grid at the refrigerating air inlet. When the water storage box rotates to directly below the housing, the sliding frame at the refrigerating air inlet slides to open the protective grid at the refrigerating air inlet.

[0021] By adopting the above technical solution, the opening and closing of the refrigerating air inlet, the heat dissipation air inlet, and the heat dissipation air outlet are realized by means of the opening and closing water-taking process of the water storage box. By default, when the water storage box rotates to directly below the housing, the refrigerating water cup is in the refrigerating working state. At this time, the refrigerating air inlet, the heat dissipation air inlet, and the heat dissipation air outlet are all in the open state. When the water storage box rotates away from the housing to take out the condensed water in the water storage box, the refrigerating air inlet, the heat dissipation air inlet, and the heat dissipation air outlet will be closed at this time.

[0022] Preferably, a filter layer is arranged in the water storage box, and the filter layer is used for cleaning and filtering the condensed water flowing into the water storage box.

[0023] By adopting the above technical solution, the filter layer is used to clean and filter the condensed water flowing into the water storage box, reducing the impurities in the external air from flowing into the water storage box together with the condensed water.

[0024] In summary, the present application includes the following beneficial technical effects: In this application, the methods of pre-cooling and cold quantity recovery are adopted, with a smaller volume and a more compact structure. The two thermoelectric coolers are arranged in the same direction, and a cooling flow channel is formed through the guiding action of the cold-end fins. The humid air absorbs the cold generated by the two thermoelectric coolers successively, achieving a better pre-cooling effect compared with the general arrangement method.

[0025] The air flowing between the fins of the cold-end fins is continuously cooled and can reach a lower temperature. Considering the heat exchange efficiency, the lower temperature will contribute to condensation. At the same time, the lower dry air temperature helps to cool the hot end after mixing with the heat dissipation air. The methods of pre-cooling and cold quantity recovery help to improve the refrigeration efficiency and provide more cold quantity within the limited input power. Description of the Drawings

Detailed Embodiment

[0033] The following is combined with the attached Figures 1-6A further detailed description of the present application will be given.

[0034] Example 1 Example 1 of the present application discloses an efficient refrigerating water cup. Referring to Figure 1 and Figure 2 , the efficient refrigerating water cup includes a housing 1 and a water storage box 2 detachably connected below the housing 1. The interior of the housing 1 is hollow and communicates with the water storage box 2. A plurality of thermoelectric cooling chips 3 are arranged inside the housing 1, and the thermoelectric cooling chips 3 are sequentially arranged along the height direction of the housing 1 above the water storage box 2. One side of the thermoelectric cooling chip 3 is a refrigerating area 11, and the other side is a heat dissipation area 12. A plurality of cold end fins 31 are arranged on the side of the thermoelectric cooling chip 3 located in the refrigerating area 11, and a plurality of hot end fins 32 are arranged on the side of the semiconductor cooling chip located in the heat dissipation area 12. A fastener 13 is also provided in the housing 1. The fastener 13 is specifically a bolt, which is used to threadedly fix the cold end fins 31 to the side wall of the thermoelectric cooling chip 3 and threadedly fix the hot end fins 32 to the side wall of the thermoelectric cooling chip 3 to achieve fixation. The cold end fins 31 are arranged along the direction parallel to the height direction of the housing 1, and a refrigerating gap 311 for air to pass through is reserved between adjacent cold end fins 31. The hot end fins 32 are arranged along the direction parallel to the width direction of the housing 1, and a heat dissipation gap 321 for air to pass through is reserved between adjacent hot end fins 32.

[0035] Referring to Figure 1 , Figure 2 and Figure 3 , a refrigerating air inlet 14 is formed through the side wall of the housing 1 near the refrigerating area 11. The refrigerating air inlet 14 is located on one side of the lowermost thermoelectric cooling chip 3; a heat dissipation air inlet 15 and a heat dissipation air outlet 16 are formed through the side wall of the housing 1 near the heat dissipation area 12; a flow guiding assembly 4 is further included. The flow guiding assembly 4 is used to extract air through the refrigerating air inlet 14 into the refrigerating area 11 for condensation, and then discharge the condensed air to the heat dissipation air outlet 16 for discharge. It is also used to extract air from the heat dissipation air inlet 15 into the heat dissipation area 12, so that the air in the heat dissipation area 12 finally flows through the hot end fins 32 and is discharged from the heat dissipation air outlet 16.

[0036] The diversion component 4 specifically includes a cold-end suction fan 41 and a hot-end heat dissipation fan 42. The cold-end suction fan 41 is located at the junction of the refrigeration area 11 and the heat dissipation area 12, and is used to suck the air in the refrigeration area 11 into the heat dissipation area 12. Also, the suction effect of the cold-end suction fan 41 can be used to create a negative pressure at the refrigerated air inlet 14, so as to promote the air outside the housing 1 to enter the refrigeration area 11 through the refrigerated air inlet 14, thereby improving the refrigeration efficiency. The hot-end heat dissipation fan 42 is located between the hot-end fin 32 and the heat dissipation air inlet 15, and is used to suck the air outside the housing 1 into the heat dissipation area 12 through the heat dissipation air inlet 15 and send it into the heat dissipation gap 321, so as to achieve the heat dissipation of the hot-end fin 32. Finally, the air inside the housing 1 will flow through the heat dissipation gap 321 and be discharged from the heat dissipation air outlet 16.

[0037] The implementation principle of the highly efficient refrigerating water cup disclosed in Embodiment 1 of this application is as follows: Start the cold-end suction fan 41 and the hot-end heat dissipation fan 42, so that the air outside the housing 1 near the refrigerated air inlet 14 enters the refrigeration area 11 in the direction shown by the arrow in the figure, and the air outside the housing 1 near the heat dissipation air inlet 15 enters the heat dissipation area 12 in the direction shown by the arrow in the figure. The air entering the refrigeration area 11 will, under the suction of the cold-end suction fan 41, first contact the bottom semiconductor refrigeration sheet 3 to achieve precooling, then flow upward and contact the top semiconductor refrigeration sheet 3 to achieve condensation and cooling to generate condensed water that adheres to the cold-end fin 31, and will slide down along the height direction of the cold-end fin 31 to the water storage box 2 under its own weight. The remaining dry air will be sucked by the cold-end suction fan 41 and flow from the top of the refrigeration area 11 into the top of the heat dissipation area 12. Part of the dry air will directly flow through the heat dissipation gap 321 at the top of the heat dissipation area 12 to the heat dissipation air outlet 16 and be discharged from the housing 1. Another part of the dry air will, under the suction of the hot-end heat dissipation fan 42, mix with the air entering the housing 1 from the heat dissipation air inlet 15 and then enter the heat dissipation area 12, and then flow to the heat dissipation gap 321 to achieve the heat dissipation of the hot-end fin 32, and finally flow through the heat dissipation gap 321 to the heat dissipation air outlet 16 and be discharged from the housing 1. In summary, high-efficiency refrigeration and increased water production are achieved.

[0038] Embodiment 2 Refer to Figure 4 、 Figure 5 and Figure 6 In Embodiment 2 of this application, the difference from Embodiment 1 is that a spoiler rod 5 is inserted through the middle of the fastener 13 along its length direction. The spoiler rod 5 is rotatably connected to the middle of the fastener 13. One end of the spoiler rod 5 extends into the heat dissipation area 12, and the other end extends into the cooling area. And spoiler blades 52 are provided on the side wall of the spoiler rod 5 along its length direction. A driving member 6 for driving the spoiler rod 5 to rotate is provided inside the housing 1.

[0039] The driving member 6 specifically includes a pressing rod 61, a linkage frame 62 and a linkage gear set 63. The linkage gear sets 63 are arranged in one-to-one correspondence with the pressing rods 61. Each linkage gear set 63 specifically includes a linkage gear sleeved on the pressing rod 61 and a linkage rack meshed with the linkage gear. All the linkage racks are commonly connected to the linkage frame 62. The linkage frame 62 is slidably connected to the inner wall of the housing 1 through a spring, and the sliding direction of the linkage frame 62 and the straight line connected by all the pressing rods 61 are both parallel to the height direction of the housing 1. The pressing rod 61 is slidably connected to the side wall of the housing 1 through a spring, and one end of the pressing rod 61 penetrates through the housing 1 and extends to the outside of the housing 1. When the spring connected to the linkage frame 62 is not deformed, the linkage frame 62 is located on the sliding path of the pressing rod 61 relative to the housing 1 for sliding; correspondingly, a butt joint surface for contacting the pressing rod 61 is provided on the side wall of the linkage frame 62 close to the pressing rod 61. The butt joint surface is used to make the linkage frame 62 slide under the pushing of the pressing rod 61 when contacting the pressing rod 61 during the sliding process, so that the linkage rod drives all the linkage gears and their corresponding spoiler rods 5 to rotate through the linkage gear set 63 during the sliding process, and the spoiler blades 52 increase the flow rate of the air in the housing 1 as the spoiler rods 5 rotate.

[0040] A filter layer 21 is provided on the inner wall of the water storage box 2. The filter layer 21 can specifically be an activated carbon layer for filtering the condensed water flowing from the inside of the housing 1 into the water storage box 2 and then flowing into the water storage box 2. The water storage box 2 is rotatably connected to the bottom wall of the housing 1 through a rotating shaft, and a telescopic member 17 is provided on the bottom wall of the housing 1. The lower end of the telescopic member 17 is arc-shaped. A limiting groove 22 for inserting the telescopic member 17 is opened on the top wall of the water storage box 2. When the water storage box 2 is located directly below the housing 1, that is, when the top wall of the water storage box 2 is completely closed and sealed by the housing 1, the lower end of the telescopic member 17 is inserted into the corresponding limiting groove 22 at this time to realize the anti-rotation of the water storage box 2 relative to the housing 1, that is, to fix the rotation position of the water storage box 2.

[0041] An opening and closing assembly 7 is further provided in the housing 1 for opening and closing the refrigerating air inlet 14, the heat dissipation air inlet 15 and the heat dissipation air outlet 16. Specifically, the opening and closing assembly 7 includes a protective grid 71, a sliding frame 72 and a return spring 73. The side walls of the housing 1 close to the refrigerating air inlet 14, the heat dissipation air inlet 15 and the heat dissipation air outlet 16 respectively correspond to a protective grid 71, and the sliding frames 72 are arranged in one-to-one correspondence with the protective grids 71. The sliding frames 72 located at the heat dissipation air inlet 15 and the heat dissipation air outlet 16 are slidably connected to the housing 1 through the return spring 73 for opening and closing the corresponding protective grids 71 during the sliding process; the return spring 73 is connected between the housing 1 and the corresponding sliding frame 72, and the telescopic direction of the return spring 73 is parallel to the sliding direction of the connected sliding frame 72.

[0042] When the return spring 73 is not deformed, the bottom of the sliding frame 72 at the heat dissipation air inlet 15 and the heat dissipation air outlet 16 extends below the housing 1, and the bottom of the sliding frame 72 is located on the rotation path of the water storage box 2 relative to the housing 1; and when the sliding frame 72 rotates to directly below the housing 1, the top wall of the water storage box 2 pushes against the bottom of the sliding frame 72 at the heat dissipation air inlet 15 and the heat dissipation air outlet 16, so that the sliding frame 72 at the heat dissipation air inlet 15 and the heat dissipation air outlet 16 moves upward and opens the protection grids 71 at the heat dissipation air inlet 15 and the heat dissipation air outlet 16, and when the water storage box 2 completely rotates to directly below the housing 1, the return spring 73 deforms; when the water storage box 2 rotates away from directly below the housing 1, the top of the water storage box 2 disengages from the contact with the bottom of the sliding frame 72, so that the sliding frame 72 moves downward under the action of its own weight and the elastic force of the return spring 73, thereby closing the protection grids 71 at the heat dissipation air inlet 15 and the heat dissipation air outlet 16.

[0043] The bottom wall of the sliding frame 72 at the refrigerating air inlet 14 is provided with docking tooth grooves 721 along its sliding direction. A docking ring 24 is sleeved on the rotating shaft at the rotating connection of the water storage box 2 and the housing 1. The docking ring 24 is provided with tooth blocks 241 for meshing with the docking tooth grooves 721. The tooth blocks 241 are used to mesh with the docking tooth grooves 721 during the sliding process of the water storage box 2 and drive the corresponding sliding frame 72 to slide and open and close the protection grid 71 at the refrigerating air inlet 14. When the water storage box 2 rotates to directly below the housing 1, the sliding frame 72 at the refrigerating air inlet 14 slides and opens the protection grid 71 at the refrigerating air inlet 14, and finally realizes the opening and closing of the refrigerating air inlet 14, the heat dissipation air inlet 15, and the heat dissipation air outlet 16, preventing dust accumulation and blockage at the refrigerating air inlet 14, the heat dissipation air inlet 15, and the heat dissipation air outlet 16 and affecting the refrigerating and heat dissipation effects.

[0044] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.

A protective grid (71) corresponds to each side wall of the housing (1) near the refrigerating air inlet (14), the heat dissipation air inlet (15) and the heat dissipation air outlet (16). The sliding frames (72) are arranged in one-to-one correspondence with the protective grids (71). The sliding frames (72) are slidably connected to the housing (1) for opening and closing the corresponding protective grids (71) during the sliding process. The sliding frames (72) located at the heat dissipation air inlet (15) and the heat dissipation air outlet (16) are respectively connected to the return springs (73). The return springs (73) are connected between the housing (1) and the corresponding sliding frames (72), and the telescopic direction of the return springs (73) is parallel to the sliding direction of the sliding frames (72). When the return spring (73) is not deformed, the bottoms of the sliding frames (72) located at the heat dissipation air inlet (15) and the heat dissipation air outlet (16) are located on the rotation path of the water storage box (2) rotating relative to the housing (1). When the sliding frames (72) rotate to directly below the housing (1), the top of the water storage box (2) pushes the bottoms of the sliding frames (72) located at the heat dissipation air inlet (15) and the heat dissipation air outlet (16), so that the sliding frames (72) located at the heat dissipation air inlet (15) and the heat dissipation air outlet (16) move upward to open the protective grids (71) at the heat dissipation air inlet (15) and the heat dissipation air outlet (16), and the return spring (73) is deformed. The bottom wall of the sliding frame (72) located at the refrigerating air inlet (14) is provided with docking tooth grooves (721) along its sliding direction. A docking ring (24) is sleeved on the rotating shaft at the rotating connection of the water storage box (2) and the housing (1). A tooth block (241) for meshing with the docking tooth grooves (721) is arranged on the docking ring (24). The tooth block (241) is used for meshing with the docking tooth grooves (721) during the sliding process of the water storage box (2) and driving the corresponding sliding frame (72) to slide and open / close the protective grid (71) at the refrigerating air inlet (14). When the water storage box (2) rotates to directly below the housing (1), the sliding frame (72) at the refrigerating air inlet (14) slides and opens the protective grid (71) at the refrigerating air inlet (14).
