Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulated boxes, and in particular to a fast hot-chain delivery insulated box. Background Technology
[0002] The existing centralized meal delivery model relies entirely on central kitchens. Fresh vegetables are cooked by chefs, loaded onto trucks, and then delivered. Of course, to reduce cooking time and increase output, central kitchens also opt for pre-prepared dishes. These dishes are typically pre-processed in food processing plants, undergoing a series of processes including handling, shaping, cooking, quick-freezing, packaging, and warehousing before being delivered to the central kitchen. However, foods like tortillas and sausages, which can be eaten after frying or steaming, are subject to further processing. Reheating after quick-freezing not only reduces their texture but also causes significant loss of nutrients.
[0003] Currently, most insulated boxes used for delivery are made of stainless steel, which has a limited heat retention time. This is extremely inconvenient for long-distance transportation, forcing the use of more expensive insulated trucks, which undoubtedly increases transportation costs. Furthermore, while placing a stainless steel box inside a foam box can improve heat retention time, the rapid thermal conductivity of stainless steel means the heat directly contacts the foam, severely shortening the foam's lifespan and negating its insulating effect. In addition, existing insulated boxes cannot maintain a constant temperature for food; the food relies solely on its own heat, which gradually decreases, often arriving at the delivery location lukewarm, negatively impacting its taste. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model provides a rapid hot-chain delivery insulated box. It features a reasonable structural design and simple, quick assembly. By effectively isolating the stainless steel layer from the foam layer, the foam box not only provides insulation but also prevents damage to the foam caused by the stainless steel box conducting heat, thus extending its service life. Furthermore, by conducting heat through the stainless steel box, food can be maintained at a relatively constant temperature, preventing temperature drops due to long transportation distances and improving the food's taste. This invention solves the problems existing in existing technologies.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0006] A rapid hot-chain delivery insulated box includes an inner box and a heat insulation component movably fitted onto the inner box, wherein the heat insulation component is disposed inside an outer box.

A through hole is provided on the retaining plate of the retaining frame corresponding to the exhaust valve position.
[0009] The outer casing includes an outer casing and an outer cover that closes at the opening of the outer casing. Heat-insulating side plates are symmetrically provided on the left and right sides of the inner wall of the outer casing. The upper end of the heat-insulating side plate abuts against the bottom of the corresponding side limiting plate. The outer end of the lower clamping plate of the clamping frame abuts against the heat-insulating side plate. Several notches are provided on the top of the outer casing, and each notch is located above the clamping frame.

Its structure is rationally designed and easy to assemble. By effectively isolating the stainless steel layer from the foam layer, the foam box not only provides insulation but also avoids damage to the foam caused by the stainless steel box conducting heat, thus improving its service life. Furthermore, by conducting heat through the stainless steel box, food can be maintained at a relatively constant temperature, preventing temperature drops due to long transportation distances, improving the taste of the food, and solving problems existing in the prior art.
