Description

Technical Field

[0001] This invention relates to a heat preservation device, specifically a heat preservation box capable of active cooling and heating. Background Technology

[0002] According to research, most insulated boxes on the market are made of different materials layer by layer. The inner and outer layers are made of different materials, and the space between the inner and outer layers is filled with insulating material. This gives the insulated box good sealing properties, which isolates the items placed inside from the outside, reduces internal energy loss, and ensures that the items are not affected by temperature and deteriorate, thus keeping the items fresh and safe for consumption. Therefore, consumers can use the insulated box for keeping things cold or hot according to their actual needs. This makes the insulated box widely used in daily life, whether it is for travel, camping and picnics, daily shopping, or even for transporting and storing medical supplies, it is quite convenient.

[0003] However, after actual use, it was found that the aforementioned insulated box does not have the ability to actively cool or heat. It can only achieve the effect of slowing down heat exchange and extending the insulation time by pre-cooling or preheating the inside to reduce the number of times it is opened during use, and by placing sufficient cold insulator or heating agent inside the insulated box. Although it can maintain the internal temperature at the beginning, the insulation effect will still decrease over time, and it is not recommended to use it for a long time. In addition, the use of cold insulator and heating agent not only occupies the storage space inside the insulated box, but can only maintain the original temperature inside the insulated box at most, and cannot substantially change the internal temperature, resulting in poor use efficiency. Furthermore, if the insulated box is used for cold preservation, the lowest temperature limit that the aforementioned methods can create is 0°C, which cannot meet the temperature requirements of specific items, thus limiting the scope of use and requiring improvement. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide an insulated box that can actively cool and heat, which effectively avoids obstruction of convection to improve the heat preservation effect, and at the same time, through modular design, it can further improve the flexibility and convenience of use.

[0005] The present invention provides an insulated box capable of active cooling and heating, comprising an outer box and a heat exchange device housed within the outer box, the heat exchange device being connected to an external power source; wherein the outer box has a box body, an opening formed on the box body, and a cover that closes to the opening to control the opening and closing state of the opening; the heat exchange device has an exhaust group, an air supply group, and a circulation pipeline connecting the exhaust group and the air supply group respectively, and the circulation pipeline is filled with a working medium;

[0006] The housing has multiple auxiliary openings. The heat exchange device has a hollow first cavity and a second cavity opposite to the first cavity. An exhaust assembly is located in the second cavity, and an air supply assembly is located between the first and second cavities, making the heat exchange device a modular design. The first cavity has a circumferential wall, a bottom wall connected to the circumferential wall, a chamber enclosed by the circumferential wall and the bottom wall, multiple air inlets on the bottom wall, an exhaust plate extending from the bottom wall and corresponding to the air supply assembly, and multiple air outlets on the exhaust plate. The air supply assembly has a first air outlet adjacent to the bottom wall. The system includes two heat exchangers and a blower located below the second heat exchanger. The exhaust assembly has a compressor connected to the second heat exchanger and a first heat exchanger located on one side of the compressor. When the heat exchange device is positioned inside the housing, the first heat exchanger of the exhaust assembly coincides with multiple auxiliary openings, dividing the housing into a storage space connected to the first cavity. Air is drawn in through multiple air inlets by the blower and heat-exchanged by the second heat exchanger. The heat-exchanged air is then discharged into the storage space through multiple air outlets. The exhaust gas generated by the heat exchange is discharged outward through the first heat exchanger via multiple auxiliary openings.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention draws air in through multiple air inlets for cooling or heating, and then discharges the heat-exchanged air into the storage space through multiple air outlets to achieve active cooling or heating. In addition, the chamber formed by the first cavity is more conducive to creating a good convection environment, and the exhaust gas generated during the heat exchange process can be discharged to the outside through multiple auxiliary openings, which further helps to improve the convection effect. Furthermore, the aforementioned modular design facilitates different configuration combinations, thereby improving the flexibility and convenience of use. Attached Figure Description

[0056] The foregoing and other technical contents, features and effects of the present invention will become clear from the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0057] See Figure 1 and Figure 7As shown, in a first preferred embodiment of the insulated box 3 capable of active cooling and heating of the present invention, the insulated box 3 includes an outer box 31 and a heat exchange device 32 disposed inside the outer box 31. The heat exchange device 32 is connected to an external power source 4 to maintain the operation of the heat exchange device 32 through the external power source 4. The external power source 4 can be DC power for vehicles or a portable power source, etc. In this embodiment, the outer box 31 is provided with a control panel 33 connected to the heat exchange device 32 to control or display necessary information through the control panel 33. The outer box 31 has a box body 311, an opening 312 opened on the box body 311, a cover 313 covering the opening 312, and a plurality of auxiliary openings 314 opened on one side of the box body 311 to control the opening and closing state of the opening 312 through the cover 313.

[0058] See Figure 2 and Figure 3 As shown, the heat exchange device 32 has a hollow first cavity 321, a second cavity 322 located below the first cavity 321, an exhaust assembly 323 installed in the second cavity 322, an air supply assembly 324 installed between the first cavity 321 and the second cavity 322, and a circulation pipe 325 connected to the exhaust assembly 323 and the air supply assembly 324 respectively. The circulation pipe 325 is filled with a working medium. The following description uses refrigerant as an example of the working medium. (See reference...) Figure 3 As shown, the first cavity 321 has a peripheral wall 3211, a bottom wall 3212 connected to the peripheral wall 3211, a chamber 3213 enclosed by the peripheral wall 3211 and the bottom wall 3212, a plurality of air inlets 3214 formed on the bottom wall 3212, an exhaust plate 3215 extending from the bottom wall 3212 toward the second cavity 322, and a plurality of air outlets 3216 formed on the exhaust plate 3215. (See attached diagram.) Figure 4 and Figure 5 As shown, in this embodiment, the exhaust plate 3215 is provided with a plurality of rectifiers 3217 to achieve the effect of guiding and stabilizing airflow. In addition, the peripheral wall 3211 and the exhaust plate 3215 are provided with a plurality of air inlets 3214, which is more conducive to introducing air and improving the convection effect.

[0059] See Figure 2 , Figure 3 and Figure 5As shown, the air supply assembly 324 has a second heat exchanger 3241 spaced apart from the bottom wall 3212, and a blower 3242 installed below the second heat exchanger 3241. The exhaust assembly 323 has a compressor 3231 connected to the second heat exchanger 3241, and a first heat exchanger 3232 installed on one side of the compressor 3231. The first heat exchanger 3232 has a fan 3232A and a fin assembly 3232B installed on one side of the fan 3232A. In this embodiment, the compressor 3231 is a DC motor compressor, so that the external power supply 4 (such as...) can be used to power the air supply assembly 3234. Figure 1 and Figure 7 The DC power supplied (as shown) causes the compressor 3231 to operate.

[0060] See Figure 2 and Figure 3 As shown, the heat exchange device 32 is manufactured with a modular design. The first chamber 321, the second chamber 322, the exhaust group 323, the air supply group 324, and the circulation pipeline 325 are all independent and have different functions. They can be assembled in different arrangements and combinations according to needs. With the aforementioned modular design, the overall configuration and process can be adjusted more quickly and easily, which is more conducive to realizing automated production. In addition, when the heat exchange device 32 is maintained, the components that need to be maintained can be removed and replaced or updated individually, which can more effectively reduce related costs and improve the flexibility and convenience of use.

[0061] See Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, this embodiment uses the application of the insulation box 3 for refrigeration as an example. After the heat exchange device 32 is manufactured and assembled, it is positioned inside the box body 311 of the outer casing 31, so that the heat exchange device 32 is accommodated and attached to one side of the box body 311. At the same time, the first heat exchanger 3232 of the exhaust assembly 323 is attached to the multiple auxiliary openings 314. The following description uses the example of the fan 3232A of the first heat exchanger 3232 being tightly fitted with the multiple auxiliary openings 314, and the fin assembly 3232B being located at the fan. Between 3232A and the compressor 3231, the heat exchange device 32 divides the interior of the housing 311 into a storage space 315. Since the first heat exchanger 3232 is closely fitted with the multiple auxiliary openings 314, the storage space 315 is not connected to the outside through the multiple auxiliary openings 314. However, the storage space 315 is interconnected with the chamber 3213 of the first cavity 321 through the multiple air inlets 3214 and the multiple air outlets 3216, and the storage space 315 and the first cavity 321 form a closed loop.

[0062] Continuing from the previous description, the items to be refrigerated are then placed into the storage space 315 through the opening 312, and the opening 312 is sealed with the cover 313. Power is then supplied by the external power source 4, and the compressor 3231 is activated via the control panel 33 to circulate the working medium through the circulation pipe 325. Simultaneously, the blower 3242 draws air from the storage space 315 through multiple air inlets 3214. The chamber 3213 formed by the first cavity 321 facilitates unobstructed air intake; the spaciousness of the chamber 3213 allows the airflow generated by the blower 3242 to pass smoothly and unimpeded. Furthermore, the exhaust plate 3215 also has multiple air inlets 3214, allowing air to be introduced through these inlets as well. Therefore, when the storage space 315 is insufficient... When used to hold items, the chamber 3213 can also be used for storage. Air can be drawn in through the air inlet 3214 on the exhaust plate 3215, thus increasing the storage space without affecting the convection effect. The air then exchanges heat with the second heat exchanger 3241 and absorbs the heat energy contained in the air through the working medium, thereby achieving a cooling effect. The cooled air then flows back into the storage space 315 through multiple air outlets 3216, so as to achieve an active cooling effect through the aforementioned circulation and ensure that the temperature in the storage space 315 does not rise over time. In addition, the closed circulation formed by the storage space 315 and the first cavity 321 helps to prevent cold air from escaping outward, thus maintaining the low temperature environment inside. When the air passes through multiple rectifiers 3217, it is guided by multiple rectifiers 3217, thereby reducing the formation of air turbulence and maintaining the stability of airflow.

[0063] Continuing from the previous description, the working medium that absorbs heat energy then moves towards the compressor 3231 through the circulation pipe 325. At this time, heat exchange occurs between the working medium and the finned assembly 3232B of the first heat exchanger 3232, absorbing the heat energy carried by the working medium. The fan 3232A then discharges the heat energy absorbed by the finned assembly 3232B through multiple auxiliary openings 314. This not only helps to cool the working medium, allowing it to continue its circulation, but also prevents the heat energy generated during the refrigeration process from being released. Instead of flowing back into the storage space 315, it is discharged to the outside of the box 311 through multiple auxiliary openings 314, which can avoid affecting the temperature inside the storage space 315 and reduce the energy consumption of the heat exchange device 32. In addition, the temperature inside the storage space 315 can be reduced to below 0°C according to actual usage needs, thereby expanding the scope of use. Furthermore, the actual space occupied by the heat exchange device 32 is almost the same as that occupied by existing cold and heat preservation agents, but the usage efficiency of the heat exchange device 32 is significantly better than that of cold and heat preservation agents.

[0064] See Figure 8 As shown, the second preferred embodiment of the present invention still includes the components described in the first embodiment, and its purpose and effect are the same as those in the first embodiment, which will not be repeated here. The special feature of this embodiment is that the exhaust group 323 has a switching valve 3233 connected to the circulation pipe 325. This embodiment is described using the heat preservation box 3 for heating purposes as an example. Therefore, the working medium is reversed by the switching valve 3233. At the same time, the compressor 3231 drives the working medium to circulate through the circulation pipe 325. When the blower 3242 draws the air in the storage space 315 through the multiple air inlets 3214, the air exchanges heat with the second heat exchanger 3241 and carries away the cold energy contained in the air through the working medium, thereby achieving the effect of heating. The heated air then flows back to the storage space 315 through the multiple air outlets 3216 (see reference). Figure 1 This achieves active heating. Furthermore, the working medium that absorbs cold energy exchanges heat with the fin assembly 3232B of the first heat exchanger 3232, thereby increasing the temperature of the working medium to facilitate its circulation. Simultaneously, the fan 3232B discharges the cold energy absorbed by the fin assembly 3232B through multiple auxiliary openings 314, ensuring that the cold energy generated during heating does not flow back into the storage space 315, significantly improving the heating effect. Therefore, given that the insulated box 3 has the ability to actively cool and actively heat, in addition to allowing the insulated box 3 to be used for a long time, it can also be used for both cold and heat preservation depending on the characteristics of the items, achieving a multi-purpose effect and further enhancing its overall functionality and practicality.

[0065] In summary, the active cooling and heating insulated box of the present invention, through the chamber formed by the first cavity of the heat exchange device, allows air to pass unimpeded through multiple air inlets and exchange heat through the second heat exchanger, and then be discharged into the storage space through multiple air outlets, thereby effectively improving the convection effect, achieving the effect of active cooling or heating, and enhancing functionality and practicality. At the same time, the exhaust gas generated during the heat exchange process can be discharged to the outside through multiple auxiliary openings, effectively preventing the exhaust gas from flowing back and affecting the internal temperature. Combined with the modular design, it is more conducive to improving the flexibility and convenience of use.

[0066] However, the above description is only for illustrating preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the patent of the present invention.
