Food box device capable of preserving heat through excess heat of cooking oil fume

Abstract

The invention discloses a food box device capable of preserving heat through excess heat of cooking oil fume. The device comprises a fan housing, wherein the big end of the air housing is clamped intoan oil storing groove, and the upper small end is connected to a fan barrel body; a filtering net is arranged between the lower end of the fan barrel body and the small end of the fan housing; an airoutlet of a fan is movably connected to an inlet of an air filter; an outlet of the air filter is connected to one end of a heating pipe of a food box through a pipeline; two ends of a spiral pipe are correspondingly connected to two ends of a heat preserving pipe; the heating pipe and the heat preserving pipe are arranged in an interlayer of a groove body which is fixedly connected to the upperpart of a frame, and a storing rack is arranged at the lower part of the frame. The food box device is compact in structure, reasonable in design, and unique and novel in idea; the oil fume and the heat are pumped as blades rotate; oil is removed by secondary filtering; hot air is transferred to heat the spiral pipe, and hot water in the spiral pipe is capable of preserving the heat of foods in aheat preserving groove. Therefore, the energy is saved; in addition, the filtered oil can be recovered, thus the waste recovery cost is increased; the hot air is recovered through the excess heat andis used as energy for heating the food groove; the running cost of a catering enterprise is decreased, and meanwhile, the air pollution is reduced; the effect is obvious; the food box device has a good application prospect and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of energy recovery and reuse, in particular to a device for heat-preserving a food box by using the residual heat of cooking fumes. Background technique [0002] The range hood is an electrical appliance for absorbing cooking fumes in the home kitchen. It can not only perform functional functions well, but also have a decorative concept that integrates the modern kitchen layout. The fan blades of range hoods have small gaps, and it is very inconvenient to clean after oil fume pollution. Often, the fan blades are easily deformed during cleaning, resulting in an imbalance in the center of gravity. [0003] In canteens and hotels, range hoods are not fully capable of removing oily fumes. Range hoods are only suitable for home kitchens. Exhauster fans are now used in canteens and hotel kitchens to remove oily fumes and purify the air in the kitchen. The situation will cause environmental pollution, which is not...

Problems solved by technology

The fan blades of the range hood have a small gap, and it is very inconvenient to clean after oil fume pollution. Often, the fan blades are easily deformed during cleaning, resulting in an unbalanced center of gravity

[0003] In canteens and hotels, range hoods are not fully capable of removing oily fumes. Range hoods are only suitable for home kitchens. Exhauster fans are now used in canteens and hotel kitchens to remove oily fumes and purify the air in the kitchen. The situation will cause environmental pollution, which is not conducive to environmental protection.

[0004] In canteens and catering enterprises, the insulated barrels and incubators used for serving meals do not have good insulation effect, and the food cools down too quickly, which cannot be well utilized in winter. This problem has always plagued the catering industry.
