Description

Technical Field

[0001] This utility model relates to the field of food cart technology, specifically a warm air dry insulated food cart. Background Technology

[0002] Food carts are typically assembled from a body and bottom casters, and most have two trays for holding food. Due to their high mobility, most food carts are often used for transporting and selling boxed meals in public areas such as trains, engineering projects, and construction sites, providing convenience for people's lives. In order to keep the food inside the food cart warm, the outer shell of the food cart is usually made of heat-insulating material to ensure that the food does not get cold during delivery and thus affect its taste.

[0003] Chinese patent publication number CN221533163U discloses a "warm air dry-type insulated food cart," comprising a box body with a door installed on the side, a push handle installed at the top rear end, and casters installed at the bottom. A partition is provided at the bottom of the box body, and an insulation layer is adhered to the inner wall of the box body above the partition. Multiple storage shelves are provided above the partition. Multiple UV lamps are installed on the inner wall of the box body away from the door, and protective covers are provided on the outside of the UV lamps. A battery and a warm air assembly are located at the bottom of the partition. This utility model has a reasonable design and simple structure, can sterilize the inside of the box body, ensuring safety and hygiene, and simultaneously achieves hot air circulation, effectively reducing heat loss and increasing energy efficiency. However, this patent cannot independently insulate each layer of the insulated box, and hot air usually accumulates at the top, resulting in a large temperature difference between the lower and upper layers, thus reducing the applicability of the insulated food cart. Therefore, we propose a warm air dry-type insulated food cart. Utility Model Content

Figure 1-5An air inlet pipe 310 is fixedly connected to the bottom of the drying chamber 300, and the end of the air inlet pipe 310 is connected to the heat insulation channel 120. An air outlet pipe 320 is fixedly connected to the top of the drying chamber 300, and the end of the air outlet pipe 320 is connected to the connecting pipe 214. An oil-water separator 330 is fixedly connected to the bottom of the inner cavity of the drying chamber 300. A drying cylinder 340 is fixedly connected to the top of the oil-water separator 330.

The drying chamber 300 is embedded in the left side wall of the insulation box 200. It is transported to the oil-water separator 330 through the air inlet pipe 310 to separate the oil and water in the air. After passing through the drying cylinder 340 for drying, the treated air is processed by the air purifier 350 and then transported to the connecting pipe 214 through the air outlet pipe 320. It is then transported to the heating pipe 221 through the branch pipe 213 and has a vent 222 to transport the air into a separate space inside the insulation box 200.

[0028] In summary, this method can improve the quality of the warm air inside the insulated food cart, thus ensuring the safety of the insulated food.

[0029] In practical use, when personnel in this technical field use insulated food carts to keep food warm and deliver it, they adjust the spacing of the sealing partitions 220 according to the size of the food. After adjustment, the sealing grooves 212 without sealing partitions 220 are sealed with sealing strips 215. The food is then placed on the sealing partitions 220, and the fan 110 delivers air into the heat-insulating channel 120. The heating element 121 heats the air, and the air intake pipe 310 delivers the air to the oil-water separator 330 to separate the oil and water in the air. The food is separated and dried inside the drying cylinder 340. The treated air is then processed by the air purifier 350 and then transported to the connecting pipe 214 through the air outlet pipe 320. It is then transported to the heating pipe 221 through the branch pipe 213 and has a vent 222 to transport the food to a separate space inside the insulated box 200 to keep the food warm. The base 100 can be moved by the handle 201 and the casters 150 to move the insulated box 200 to the delivery position.

[0030] It is worth noting that the oil-water separator 330, drying cylinder 340, and air purifier 350 are all existing technology products. The oil-water separator 330 includes an inlet pipe and mixing chamber, a sedimentation / separation chamber, and an oil collection and drainage system. Oily wastewater is pumped into the mixing chamber, where a stable emulsion is formed by an agitator and disperser, preparing for subsequent separation. It includes an inclined plate / corrugated plate structure, utilizing gravity or centrifugal force to accelerate oil droplet sedimentation. Some designs employ honeycomb-shaped partitions, further separating trace oil droplets through three-way flow reversal, dividing the system into left and right oil collection chambers to collect oil droplets of different sizes. Clean water is discharged through a drain outlet, while sludge is discharged through a solenoid valve / manual valve. Some units are equipped with an automatic slag removal device to filter solid impurities.

[0031] The drying cylinder 340 includes an air inlet, an air outlet, an exhaust outlet, and a regeneration system. The air inlet is located at the top of the tower, while the air outlet and exhaust outlet are located at the bottom. The core component is the desiccant. Wet materials (such as fuel oil or solution) enter the drying tower through the air inlet and come into full contact with hot air (or nitrogen). The micropores on the surface of the desiccant adsorb moisture, and the water vapor is discharged through the air outlet. The dried material is discharged through a cyclone separator. During the regeneration process, after the adsorbent is saturated, moisture is released by heating or depressurization, forming humid air that is discharged through the exhaust outlet. Some equipment uses hot regeneration (heated air) or cold regeneration (depressurization) to restore adsorption capacity. In spray drying (special type), some drying towers combine spray technology to atomize the liquid into tiny droplets that flow in parallel with hot air, quickly drying them into granular products. The finished product is discharged after cyclone separation and bag dust removal.

[0032] The Air Purifier 350 includes a motor, fan, filtration system, and purification module. The filtration system comprises a mechanical filter, an activated carbon filter, and an electrostatic precipitator filter. The motor drives the fan to draw in air, which is filtered through multiple layers of filters to remove particulate matter and gaseous pollutants. Finally, purified air is discharged. The air purifier actively releases purifying agents through technologies such as negative ions and ultraviolet light, covering a wider range of pollutants. It is especially suitable for handling bacteria, viruses, and difficult-to-filter gases. Combining these two technologies, it balances efficiency and coverage, making it suitable for complex environmental needs.
