Description

[Technical Field]

[0001] This utility model relates to the field of outdoor products technology, specifically to a device with heat preservation and air conditioning functions. [Background Technology]

[0002] Outdoor activities such as camping, picnicking, fishing, or car travel often require addressing both the need to keep food and drinks refrigerated and the need for people to stay cool. Currently, the common practice is to carry an insulated box filled with ice for refrigeration and an additional portable fan or small air cooler for cooling. This approach has several inconveniences: First, it requires carrying multiple separate devices, increasing the burden of travel and the storage space they occupy; second, traditional portable air conditioners or high-efficiency air coolers typically require independent cooling systems (such as compressors or thermoelectric coolers) and large-capacity power supplies, resulting in bulky equipment, high power consumption, and poor outdoor battery life.

[0003] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0004] The technical problem this invention aims to solve is to provide a device with both heat preservation and air conditioning functions. This device includes an insulated box and a cover component that fits over it. The insulated box forms an insulated cavity for storing ice and / or ice water. The cover component has an airflow channel with an air inlet communicating with the insulated cavity and an air outlet for blowing air outwards. A fan is installed inside the cover component, and a cooling mechanism is installed within the airflow channel. The fan drives air from inside the insulated box into the airflow channel through the air inlet. After being cooled by the cooling mechanism, the air forms a cool airflow that is blown out through the air outlet for cooling purposes. The device also has an openable / closable air inlet to balance the air pressure inside the insulated cavity when the fan is operating. This invention efficiently integrates refrigeration and air conditioning functions, using the ice water inside the box as a cold source, to solve the problem of having to carry both an insulated box for refrigeration and an additional fan when traveling. This application can be used as an insulated box and also regulates air temperature, outputting cool air for users to cool off outdoors. It greatly simplifies outdoor equipment and improves convenience.

[0019] As described above, in the device with heat preservation and air conditioning functions, the air inlet is located on one side of the heat preservation cavity, and the air replenishment port is connected to the heat preservation cavity and is located on the side away from the air inlet.

[0020] As described above, the device with heat preservation and air conditioning functions has a rotating wheel at the bottom of the heat preservation box and a pull rod hinged to the upper part of the heat preservation box, which can naturally stick to the heat preservation box under the action of gravity to achieve folding.

Detailed Implementation Methods

[0047] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0048] like Figure 1-9As shown, this utility model includes a device with heat preservation and air conditioning functions, comprising an insulated box body 1, a cover component 2, a fan 3, a cooling mechanism 4, and an air inlet 5. The insulated box body 1 can be a cuboid or approximately cuboid structure, forming an upward-opening insulated cavity 10 for storing food and beverages requiring refrigeration and preservation. Ice cubes or ice packs can be directly placed inside, creating an ice-water coexistence state after the ice melts. The insulated box body 1 includes an outer shell 11, an inner shell 12, and an insulation layer 13 disposed between the outer shell 11 and the inner shell 12. The outer shell 11 provides structural strength and aesthetic protection, while the inner shell 12 directly contacts the storage space, ensuring safety and hygiene. The intermediate insulation layer 13 prevents heat exchange between the inside and outside. The insulation layer 13 can be filled with PU foam or a composite insulation material of PU+VIP.

[0049] The cover component 2 covers the opening of the insulation box 1. The cover component 2 can be connected to the opening by means of hinges or snaps. In this application, a hinged method is preferred to facilitate user opening. The cover component 2 has an air flow channel 20 inside. The air flow channel 20 has an air inlet 21 communicating with the insulation cavity 10 and an air outlet 22 for blowing air to the outside. A fan 3 is provided on the insulation box 1 or the cover component 2. The fan is a centrifugal fan or an axial fan. A cooling mechanism 4 is provided in the air flow channel 20. The fan 3 is used to drive the air in the insulation box 1 to enter the air flow channel 20 from the air inlet 21, flow through the cooling mechanism 4 to cool down, and form a cold airflow that is blown out from the air outlet 22 for user cooling. An air supply port 5 is provided on the insulation box 1 or the cover component 2 to connect the insulation cavity 10 with the outside.

[0050] In this application, the fan 3 can be located within the airflow channel 20, such as within the airflow channel 20 at the air outlet 22 or at the air inlet 21, or at the air supply port 5. It is used to draw air from the outside into the insulation cavity 10, creating positive pressure inside the insulation cavity 10. Air inside the insulation cavity 10 can then enter the airflow channel 20 from the air inlet 21 and be blown out from the air outlet 22. In this application, it is preferable to locate the fan 3 within the airflow channel 20 between the air outlet 22 and the cooling mechanism 4, which allows for a stronger airflow.

[0051] like Figure 2 As shown, a drain valve 8 is installed on one side of the bottom of the insulated box 1 for easy maintenance and cleaning. When the ice inside the box has completely melted, or when it is necessary to clean the water inside the box, simply open this drain valve 8 to drain the water smoothly without having to tip over the entire heavy box, making it very convenient to use.

[0052] like Figure 3As shown, for ease of use, this embodiment includes a dedicated chamber (not shown) inside the cover component 2 for housing the battery 9 (such as a lithium-ion battery pack). The battery 9 can be charged via a charging interface (such as USB-C or DC port) on the cover component 2. The fan 3 is electrically connected to the battery 9 via wires and is directly powered by the battery 9. This eliminates the device's dependence on a fixed power source, allowing the air conditioning function to be activated anytime, anywhere, truly meeting the needs of outdoor mobile use. Additionally, a solar panel can be installed on the cover component 2 to charge the battery 9.

[0053] When cooling is needed, the fan 3 is turned on, driving the cold air inside the insulation cavity 10 (which is at a lower temperature due to contact with ice) to be drawn into the airflow channel 20 through the air inlet 21. This cold air then flows through the cooling mechanism 4, where further heat exchange occurs, further reducing its temperature and creating an even lower "cold airflow". Finally, the enhanced cooling airflow, driven by the fan 3, is blown out at high speed from the air outlet 22 to the user, achieving a rapid cooling effect.

[0054] like Figure 3 and Figure 5 As shown, because the fan 3 continuously draws air out of the insulation cavity 10, a slight negative pressure is generated in the insulation cavity 10, affecting airflow. Therefore, an openable and closable air inlet 5, such as a vent with a rubber plug or rotating cover, is provided on the side wall or cover component 2 of the insulation box 1. When the fan 3 is working, the air inlet 5 is opened, allowing external air to slowly flow into the insulation cavity 10, balancing the internal and external air pressure and ensuring smooth airflow circulation. This air inlet 5 can be closed when not in use to maintain the insulation performance of the box.

[0055] Specifically, the cooling mechanism 4 includes a cooling element 40 and a heat exchange assembly 41. The cooling element 40 is detachably disposed in the air flow channel 20 to reduce the temperature of the air flowing through it. The cooling element 40 can be block-shaped or plate-shaped, and has pores for air flow. When air flows through its surface or internal pores, it absorbs heat from the air, thereby reducing the air temperature.

[0056] like Figure 7As shown, the heat exchange component 41 is disposed between the cooling element 40 and the insulation cavity 10, and is used to facilitate heat exchange between the cooling element 40 and the low-temperature medium. By setting the heat exchange component 41, heat exchange between the cooling element 40 and ice or ice water can be effectively achieved, keeping the cooling element 40 at a low temperature and thus ensuring its continuous cooling capacity. The cooling element 40 is a wet film, porous ceramic, or hydrophilic fiber mesh structure. These materials share the characteristic of allowing air circulation and absorbing a large amount of heat from the flowing air, resulting in more thorough air cooling. In this application, a wet film is preferred. This refers to honeycomb paper or polymer material evaporation curtains commonly used in water-cooled air conditioners, which have a fast water absorption rate and a large specific surface area, thus improving the heat exchange rate.

[0057] like Figure 9 As shown, the cooling component 40 is designed to be detachable, which facilitates cleaning and replacement. For example, a slot 23 communicating with the air flow channel 20 is provided on one side of the cover component 2, and the cooling component 40 can be inserted into the slot 23. A cover plate 24 is provided at the opening of the slot 23 to fix the cooling component 40 in the slot 24.

[0058] like Figure 3 , Figures 6 to 8 As shown, to achieve the above solution, an implementation method is provided. The heat exchange component 41 is a water pump, which is located in the cover component 2 or the insulation cavity 10, and is used to pump the cooling liquid in the insulation cavity 10 to the cooling element 40. When the water pump is located in the cover component 2, the water inlet of the water pump extends to the bottom of the insulation cavity 10 through an inlet pipe (not shown in the figure) and is immersed in the ice-water mixture. The water outlet of the water pump is connected to the top of the cooling element 40 (such as a wet film) through another outlet pipe. When the water pump is working, it directly pumps the low-temperature ice water at the bottom of the insulation cavity 10 to the top of the cooling element 40, and evenly sprays or wets the entire cooling element 40. The low-temperature liquid forms a water film on the surface of the cooling element 40 and flows down, which directly cools the material itself on the one hand, and on the other hand, the water film can strongly absorb the heat flowing through the air when it evaporates. The water that flows down can be collected and guided back to the insulation cavity 10, forming a circulation, thereby efficiently and continuously transferring the cooling capacity from the bottom of the chamber to the air channel 20 for utilization. The height of the air channel 20 gradually decreases from the air outlet 22 to the air inlet 11, which prevents water from flowing out of the air outlet 22. When the water pump is installed in the insulation cavity 10, it is located at the bottom of the insulation cavity 10, and its outlet pumps water to the cooling component 40 through a pipe.

[0059] Furthermore, a first nozzle 25 is also provided at the air outlet 22. Multiple first nozzles 25 can be provided, and each first nozzle 25 is connected to the outlet of the water pump via a pipe. When the equipment is working, a portion of the pumped chilled water is not only used to wet the cooling component 40, but is also diverted to the first nozzles 25. The first nozzles 25 atomize the chilled water into extremely fine water mist, which is then sprayed into the cold airflow about to exit the air outlet 22. This water mist evaporates rapidly in the airflow, instantly absorbing a large amount of heat, thus providing "secondary cooling" to the airflow. The sprayed water mist also has a decorative effect.

[0060] Furthermore, the first nozzle 25 is rotatably and adjustablely located at the air outlet 22, allowing the user to adjust the spray angle as needed. To prevent clogging or damage to the first nozzle 25, it can be detachably located at the air outlet 22, for example, by means of screw tightening or snap-fitting.

[0061] Furthermore, a second nozzle is provided at the air inlet 21. The second nozzle is connected to the outlet of the water pump via a pipe, so that the water pumped by the water pump passes through part of the air flow channel 20 before being sprayed onto the cooling component 40. The fine water mist or droplets sprayed from the second nozzle do not fall directly onto the cooling component 40, but are first sprayed into the air flow channel 20 between the air inlet 21 and the wet film. In this way, the airflow passing through is also cooled, and the water is also sprayed onto the wet film to improve utilization. It should be noted that the second nozzle is not shown in the figure.

[0062] To achieve the above solution, another implementation is provided. The heat exchange component 41 is a heat exchanger provided on the side wall of the insulation cavity 10. The bottom of the heat exchanger extends to the bottom of the insulation cavity 10. After the cover component 2 is closed, the cooling component 40 contacts the top of the heat exchanger. The heat exchanger is made of a material with good thermal conductivity (such as aluminum alloy, copper, or thermally conductive plastic), and its shape can be plate-shaped, column-shaped, or have an embedded pipeline structure. The heat exchanger is pre-embedded or fixed inside the side wall of the insulation box 1 (i.e., between the outer shell 11 and the inner shell 12). Its bottom extends downwards, reaching deep into the bottom of the insulation cavity 10, so as to fully contact or immerse it in the low-temperature medium (ice water). Its top extends upwards, protruding from the upper edge of the side wall of the box when the cover component 2 is closed. Correspondingly, a matching contact surface is provided below the cooling component 40 (e.g., a metal heat-conducting plate or a metal substrate combined with a wet film) inside the cover component 2. When the cover component 2 is closed, the lower surface of the cooling component 40 is in close contact with the top of the heat exchange component, forming a good heat conduction path. In this way, the ice water and ice blocks in the insulation cavity 10 can exchange heat with the cooling component 40 through the heat exchange component, keeping the cooling component 40 at a low temperature, thereby cooling the flowing air. This solution eliminates the need for water pumps and pipelines, resulting in a simpler structure and higher reliability. It should be noted that the heat exchange component is not shown in this application.

[0063] like Figure 4 As shown, the airflow channel 20 is further non-linear. Specifically, it can be U-shaped, S-shaped, or L-shaped. The main purpose of this design is to increase the effective length of the airflow channel 20, reduce the airflow velocity, and extend the contact time between the air and the cooling component 40. This allows for more thorough contact between the air and the cooling component 40, facilitating more complete heat exchange and improving the final cooling effect. Simultaneously, the non-linear flow channel also allows for the arrangement of longer cooling paths within a limited space, resulting in a more compact equipment structure.

[0064] like Figure 3 As shown, the air inlet 21 is located on one side of the insulation cavity 10, and the air supply port 5 is connected to the insulation cavity 10 on the side away from the air inlet 21. The air inlet 21 is located on the right side of the insulation cavity 10, and the air supply port 5 is located on the left side. This allows external air to slowly traverse the entire insulation cavity 10 after entering through the air supply port 5 when the fan 3 is operating, resulting in more thorough cooling, before being drawn into the air inlet 21. This ensures air pressure balance and pre-cools the supplied air to a certain extent, improving the overall cooling efficiency of the system.

[0065] like Figure 1As shown, furthermore, to improve the portability of the equipment, the bottom of the insulated box 1 is equipped with casters 6, and the upper part of the insulated box 1 is hinged with a pull rod 7 that can naturally adhere to the insulated box 1 under the action of gravity to achieve folding. This saves space and keeps the appearance neat. When it is necessary to move, the pull rod 7 can be pulled up to easily drag the entire equipment, greatly reducing the user's carrying burden.

[0066] To enhance user experience and ensure targeted delivery of cool air, this embodiment includes one or more air guide vanes installed at the air outlet 22. These vanes are rotatably connected to the frame of the air outlet 22 via a pivot. Users can manually move the vanes up and down or left and right to change the direction of airflow, making it more flexible and comfortable to use. It should be noted that the air guide vanes are not shown in the diagram.
