Description

Technical Field:

[0001] The utility model relates to the technical field of fan products, and particularly refers to a refrigeration device. Background Art:

[0002] A thermoelectric cooler (TEC) is made using the Peltier effect of semiconductor materials. The so-called Peltier effect refers to the phenomenon that when a direct current passes through an electric couple composed of two semiconductor materials, one end absorbs heat and the other end releases heat. Heavily doped N-type and P-type bismuth telluride are mainly used as the semiconductor materials of the TEC. The bismuth telluride elements are electrically connected in series and generate heat in parallel. The TEC includes some P-type and N-type pairs (groups), which are connected together through electrodes and sandwiched between two ceramic electrodes; when current flows through the TEC, the heat generated by the current will be transferred from one side of the TEC to the other side, generating a "hot" side (i.e., the hot surface) and a "cold" side (i.e., the cold surface) on the TEC. This is the heating and refrigeration principle of the TEC.

[0003] The inventor of the present application has filed a Chinese utility model patent application with the patent application number 202322355548.5 and the title of "Refrigerator and Refrigeration Clothing Using the Same". The refrigerator includes a housing, a TEC refrigeration module installed in the housing, and a fan. An air inlet cavity and an air outlet cavity are provided in the housing and are communicated with each other. The fan is arranged in the air inlet cavity; the TEC refrigeration module is arranged in the air outlet cavity, and a cold air channel and a hot air channel are formed in the air inlet cavity; natural air inlets and heat exhaust ports are respectively arranged on both sides of the lower end surface of the housing. The natural air inlets are communicated with the air inlet cavity and correspond to the fan. The heat exhaust ports are communicated with the hot air channel. A cold air outlet communicating with the cold air channel is arranged on one side of the upper end surface of the housing, and a cold air inlet communicating with the air inlet cavity is arranged on the other side of the upper end surface of the housing. The cold air inlet corresponds to the air inlet cavity communicated with the fan, making the air inlet cavity become a mixed hot and cold air cavity, enabling the refrigerator to achieve a refrigeration internal cycle, not only improving the refrigeration effect of the TEC refrigeration module, reducing the energy consumption when the TEC refrigeration module works, but also providing colder air to meet the usage requirements.

[0004] The above-mentioned cooler has the following problems during use: During the use of the above-mentioned air inlet cavity, it directly becomes a hot and cold air mixing cavity, and the formed hot and cold air blows towards the cold guide body and the heat conducting body of the TEC cooling module simultaneously after passing through the air outlet cavity. Although this method can enable the cooler to achieve a refrigeration internal cycle, it cannot control whether a hot and cold air mixing cavity needs to be formed, and it cannot meet the user's requirements. Moreover, the air inlet cavity is supplied with air from both the cold air inlet and the natural air inlet. Since the natural air inlet is connected to the outside, the air intake volume will be relatively large. There is a possibility that the natural air entering from the natural air inlet blocks the cold air from entering the cold air inlet, or it will affect the amount of cold air received by the cold air inlet, resulting in the inability to improve the refrigeration effect of the TEC cooling module well, or only slightly improving the refrigeration effect of the TEC cooling module. At the same time, it cannot provide colder air with a larger temperature difference, causing greater trouble to the user.

[0033] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0034] See Figures 1-15 As shown, it is a refrigeration device, which includes a housing 3, a TEC refrigeration module 4 and a fan 100.

[0035] An air inlet cavity 301 and an air outlet cavity 302 which are connected are arranged inside the housing 3, and the fan 100 is arranged in the air inlet cavity 301; the TEC refrigeration module 4 is arranged at the rear side of the air outlet cavity 302, and a cold air channel 303 and a hot air channel 304 corresponding to the cold guide body 41 and the heat conducting body 42 in the TEC refrigeration module 4 are respectively arranged inside the rear end of the housing 3; an internal air inlet 305 and an external air inlet 306 communicating with the air inlet cavity 301 are respectively arranged on the upper and lower surfaces of the front end of the housing 3, and a cold air port 307 and a heat dissipation port 308 communicating with the cold air channel 303 and the hot air channel 304 respectively are arranged at the rear end of the housing 3.

[0036] The present utility model has mainly made the following improvements: The fan 100 has a second air extraction channel 221 and a first air extraction channel 211 that are separated from each other and respectively communicate with an internal air inlet 305 and an external air inlet 306; A movable wind deflector 5 is arranged in the air outlet cavity 302, and the wind deflector 5 divides the air outlet cavity 302 into two independent first air channels 3021 and second air channels 3022 that respectively communicate with the first air extraction channel 211 and the second air extraction channel 221, and the wind deflector 5 is also docked with a TEC cooling chip 43 in the middle of the TEC cooling module 4; A driving member 6 is further arranged on the outer shell 3 for driving the wind deflector 5 to move or rotate so that the first air channel 3021 and the second air channel 3022 communicate. That is to say, first of all, the present utility model defines that the fan 100 has a second air extraction channel 221 and a first air extraction channel 211 that are separated from each other and respectively communicate with an internal air inlet 305 and an external air inlet 306, and a wind deflector 5 and a driving member 6 for driving the wind deflector 5 to move or rotate are added. Among them, the wind deflector 5 can dock the fan 100 and the TEC cooling chip 43, and divides the air outlet cavity 302 into two independent first air channels 3021 and second air channels 3022 that respectively communicate with the first air extraction channel 211 and the second air extraction channel 221. In this way, when the fan 100 works in a normal state, the fan 100 sucks air through the internal air inlet 305 through the second air extraction channel 221 and blows it to the heat conduction body 41 through the second air channel 3022 to form cold air, and the cold air is output from the cold air outlet 307 after passing through the cold air channel 303. At the same time, the fan 100 sucks air through the external air inlet 306 through the first air extraction channel 211 and blows it to the heat conduction body 42 through the first air channel 3021 to form hot air, and the hot air is output from the heat dissipation outlet 308 after passing through the hot air channel 304, so as to achieve the purpose of double air intake and double air outlet, and the air sucked by the fan 100 through the internal air inlet 305 and the external air inlet 306 does not affect each other, and is separated by the second air extraction channel 221 and the first air extraction channel 211 respectively, so as to achieve the purpose of non-air leakage, ensure the air intake of the internal air inlet 305 and the external air inlet 306, make the fan 100 run more stably. The above design can also improve the refrigeration effect of the TEC cooling module, and can ensure that the cold air / cold wind with a larger temperature difference is output from the cold air outlet 307 to meet the use requirements. If it is found that the hot air output from the heat dissipation outlet 308 is too hot, the user can drive the wind deflector 5 to move or rotate through the driving member 6 so that the first air channel 3021 and the second air channel 3022 communicate, so as to form a small hot and cold air mixing cavity in the air outlet cavity, make the air blown to the heat conduction body 42 in the TEC cooling module have a lower temperature, and then facilitate the heat dissipation of the heat conduction body 42, and then can also improve the refrigeration capacity of the TEC cooling module. Therefore, the present utility model can artificially control whether the air outlet cavity needs to form a hot and cold air mixing cavity to meet the user's use requirements.

[0037] The utility model can be applied to clothes to form a refrigerated garment. Among them, the internal air inlet 305 and the cold air outlet 307 communicate with the inside of the clothes to form a circulating refrigeration, that is, the cold air discharged from the cold air outlet 307 can circulate into the internal air inlet 305. The external air inlet 306 and the heat dissipation outlet 308 are exposed outside the clothes to communicate with the outside world.

[0038] An isolation plate 7 is arranged in the inner cavity at the rear end of the housing 3. The isolation plate 7 divides the inner cavity at the rear end of the housing 3 into the cold air channel 303 and the hot air channel 304, and the isolation plate 7 is butted against the TEC refrigeration chip 43.

[0039] The assembly structure of the windshield 5 and the housing 3 is as follows:

[0040] Shaft bodies 51 are arranged at both ends on one side of the windshield 5. The shaft bodies 51 are installed in the housing 3 so that the windshield 5 can rotate relative to the housing 3. Among them, in order to ensure that the windshield 5 can stably divide the air outlet cavity into the first air duct 3021 and the second air duct 3022, the following design is also made: A spring 52 is arranged between the lower end surface of the other side of the windshield 5 and the housing 3. The spring 52 acts upward to lift, and a blocking portion 431 for preventing the other side of the windshield 5 from being lifted excessively is arranged on the housing 3 or the TEC refrigeration module 4. As a result, in the normal state, the windshield 5 can stably divide the air outlet cavity into the first air duct 3021 and the second air duct 3022. When the windshield 5 is driven by the driving member 6 to be pressed down, the spring will be compressed. When the driving member 6 is reset, the spring is reset, and then the windshield 5 automatically resets.

[0041] The blocking portion 431 is formed by extending from the end of the TEC refrigeration chip 43 of the TEC refrigeration module 4. Of course, the blocking portion 431 can also be a baffle arranged inside the housing 3.

For more convenient assembly, the outer shell 3 is divided into an upper shell 31 and a lower shell 32. Both the upper shell 31 and the lower shell 32 are provided with groove bodies, and the two groove bodies are combined to form the sliding hole 309. During assembly, first hang the sliding portion 61 of the driving member 6 in the groove body of the upper shell 31 / lower shell 32, and then assemble the upper shell 31 and the lower shell 32 to form the outer shell 3, and the assembly of the driving member 6 can be completed. The pushing key 62 is placed on the outer surface of the outer shell 3, which is convenient for the user to drive the pushing key 62 to move. The driving portion 63 is placed inside the outer shell 3, and the driving portion 63 is provided with a driving inclined surface 631, and the driving inclined surface 631 contacts the windshield 5. When the pushing key 62 is pushed, the other side of the windshield 5 is driven to press down by the driving inclined surface 631 of the driving portion 63, so as to drive the windshield 5 to rotate. Wherein, a limiting notch 53 is provided on the other side of the windshield 5, and the driving portion 63 is placed in the limiting notch 53, so as to ensure that the driving portion 63 can stably drive the windshield 5 to rotate.

[0043] In order to better push the pushing key 62, a number of anti-slip ridges 621 are further provided outside the pushing key 62.

[0044] A stop bar 50 for preventing the other side of the windshield 5 from being pressed down excessively by the driving member 6 is further provided at the lower end of one side of the windshield 5; when the windshield 5 rotates to a certain angle, the stop bar 50 will contact the end of the fan, so as to prevent the windshield 5 from being pressed down excessively by the driving member 6, that is, to prevent the windshield 5 from rotating excessively.

[0045] A first cylinder 54 is provided on the lower end surface of the other side of the windshield 5, a second cylinder 300 is provided inside the outer shell 3, the upper end of the spring 52 is sleeved and fixed on the first cylinder 54, and the lower end of the spring 52 is sleeved and fixed on the second cylinder 300, so as to ensure that the spring 52 is stably installed between the windshield 5 and the outer shell 3.

[0046] Combined with Figures 9-15 As described above, the fan 300 includes: a housing 1, a motor assembly (not shown in the figure), and a turbine fan blade 2.

[0047] An air outlet 13 and a partition piece 14 located in the air outlet 13 are provided on the outer side of the housing 1. The partition piece 14 divides the air outlet 13 into a first air outlet 131 and a second air outlet 132 that are vertically isolated and respectively correspond to the second air duct and the first air duct. The partition piece 14 corresponds to the windshield 5. A first air inlet 15 and a second air inlet 16 that respectively correspond to an external air inlet and an internal air inlet are provided at the upper and lower ends of the housing 1. A motor assembly is installed in the housing 1. The turbine fan blade 2 is installed on the motor assembly and is located in the housing 1. After being powered on, the motor assembly drives the turbine fan blade 2 to rotate, which is a conventional technology. A partition plate 20 is provided in the middle of the turbine fan blade 2. The turbine fan blade 2 is divided into an upper turbine fan body 21 and a lower turbine fan body 22 that respectively correspond to the first air inlet 15 and the second air inlet 16 by the partition plate 20. The partition plate 20 corresponds to the partition piece 14, and a first air duct is formed between the first air inlet 15, a first air extraction channel 211 in the upper turbine fan body 21, and the first air outlet 131. A second air duct that is separated from the first air duct is formed between the second air inlet 16, a second air extraction channel 221 in the lower turbine fan body 22, and the second air outlet 132.

[0048] The fan in the present utility model has mainly made the following improvements: First, a first air inlet 15 and a second air inlet 16 corresponding to an external air inlet and an internal air inlet are respectively provided at the upper and lower ends of the housing 1. A partition piece 14 is used to divide the air outlet 13 into a first air outlet 131 and a second air outlet 132 that are vertically isolated and respectively correspond to a second air duct and a first air duct. At the same time, a partition plate 20 corresponding to the partition piece 14 is provided in the middle of the turbine fan blade 2.

During operation, the turbine fan blade 2 is driven to rotate by the motor assembly. During the rotation of the turbine fan blade 2, the upper turbine fan body 21 and the lower turbine fan body 22 respectively draw air inwards from the outside in two directions through the first air inlet 15 and the second air inlet 16, so that external air flows into the interior of the housing 1 and is discharged through the first air outlet 131 and the second air outlet 132 respectively to form an air flow. Since the first air inlet 15 and the second air inlet 16 draw air inwards from the outside in two directions, the air intake volume is large, and at the same time, the air output volume can be enhanced to meet the use requirements of high air volume. That is, the present utility model can achieve double air intake and double air output through two mutually separated first air ducts and second air ducts, achieving the functions and effects of two fans with one fan. Its structure is simple and compact, and the cost can be effectively reduced, improving the market competitiveness. At the same time, since the first air inlet 15 and the second air inlet 16 draw air inwards from the outside in two directions, the use requirements of two-way air intake can be met, and air is discharged through the two different air outlets of the first air outlet 131 and the second air outlet 132 to meet the use requirements of independently blowing air to two different positions (i.e., a heat conducting body and a heat dissipating body) without air leakage, making the present utility model have stronger market competitiveness.

The first air inlet 15 and the second air inlet 16 are respectively communicated with the upper cavity and the lower cavity, and the upper turbine fan body 21 and the lower turbine fan body 22 are respectively placed in the upper cavity and the lower cavity.

[0050] The housing 1 includes an upper housing 11 and a lower housing 12 that are stacked and fixed together up and down. The motor assembly is installed on the lower housing 12. The partition piece is integrally formed at the lower part of the upper housing 11, so that the first air outlet 131 is formed on the outside of the upper housing 11. Its structure is simple and stable. A groove 121 is provided on the outside of the lower housing 12, and the partition piece 14 covers the upper end of the groove 121 to form the second air outlet 132.

[0051] A flange 122 is provided on the outer side of the upper end of the lower housing 12, and a clamping groove 111 is provided on the outer side of the lower end of the upper housing 11. The clamping groove 111 is fitted into the flange 122 to form positioning.

[0052] A plurality of snap rings 112 are provided at the lower end of the upper housing 11. A guiding groove 113 is provided on the inner side of the snap ring 112. A plurality of buckles 123 adapted to the snap rings 112 are provided at the upper end of the lower housing 12. The buckles 123 pass through the guiding grooves 113 and are buckled and fixed with the snap rings 112.

[0053] The turbine fan blade 2 includes a hub 23 assembled with the motor assembly and a plurality of blades 24 integrally formed on the periphery of the hub 23 and distributed at intervals. A partition 20 is integrally connected between the middle parts of two adjacent blades 24, so that the blade 24 is divided into a first blade body 241 and a second blade body 242. The upper end of the first blade body 241 and the partition 20 form the upper turbine fan body 21, and the lower end of the second blade body 242 and the partition 20 form the upper turbine fan body 21. A first air extraction channel 211 corresponding to the first air inlet 15 is formed between the upper end surface of the partition 20 and two adjacent first blade bodies 241, and a second air extraction channel 221 corresponding to the second air inlet 16 is formed between the lower end surface of the partition 20 and two adjacent second blade bodies 242. Specifically, during operation, when the turbine fan blade 2 rotates, the upper first blade body 241 extracts air from the first air inlet 15, and after passing through the first air extraction channel 211, it is discharged from the first air outlet 131. At the same time, the lower second blade body 242 extracts air from the second air inlet 16, and after passing through the second air extraction channel 221, it is discharged from the second air outlet 132. At this time, the air intake amounts of the first air inlet 15 and the second air inlet 16 can be made the same to meet the usage requirements that the air intake amounts of the first air inlet 15 and the second air inlet 16 are the same.

[0054] The inner side of the partition 20 is integrally connected to the periphery of the hub 23, and the outer side of the partition 20 extends to the outer end of the blade 24 and is flush with the outer end of the blade 24. Its structure is extremely stable, and all the blades 24 are connected together, ensuring that the entire turbine fan blade structure is more stable, has high strength, and long service life.

[0055] The outer end of the blade 24 is larger than the inner end in size, and the first blade body 241 and the second blade body 242 have the same shape and are symmetrically distributed in a mirror image, and it has a stronger air extraction effect.

[0056] The blades 24 are vertically distributed on the periphery of the hub 23, and the cross section of the blade 24 is in an inclined J shape.

[0057] In summary, when the fan 100 operates in the normal state, the fan 100 sucks air through the internal air inlet 305 via the second air extraction channel 221 and blows it to the heat conduction body 41 through the second air duct 3022 to form cold air. The cold air is output from the cold air outlet 307 after passing through the cold air channel 303. At the same time, the fan 100 sucks air through the external air inlet 306 via the first air extraction channel 211 and blows it to the heat conduction body 42 through the first air duct 3021 to form hot air. The hot air is output from the heat dissipation outlet 308 after passing through the hot air channel 304, thereby achieving the purpose of double air intake and double air outlet. Moreover, the air sucked in by the fan 100 through the internal air inlet 305 and the external air inlet 306 does not affect each other and is separated by the second air extraction channel 221 and the first air extraction channel 211 respectively, thereby achieving the purpose of non-crossing air flow, ensuring the air intake volume of the internal air inlet 305 and the external air inlet 306, and making the operation of the fan 100 more stable. The above design can also improve the refrigeration effect of the TEC refrigeration module, and can ensure that colder cold air / cold wind is output from the cold air outlet 307 to meet the use requirements. If it is found that the hot air output from the heat dissipation outlet 308 is overheated, the user can drive the baffle 5 to move or rotate through the driving member 6 so that the first air duct 3021 and the second air duct 3022 are connected, thereby forming an air outlet cavity to form a small hot and cold air mixing cavity, making the air blown to the heat conduction body 42 in the TEC refrigeration module have a lower temperature, thereby facilitating the heat dissipation of the heat conduction body 42, and further improving the refrigeration capacity of the TEC refrigeration module. Therefore, the present utility model can artificially control whether the air outlet cavity needs to form a hot and cold air mixing cavity to meet the use requirements of the user.

[0058] Certainly, the above are only specific embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present utility model shall be included in the scope of the patent application of the present utility model.
