The hot air flow enters the heating room, the cold fluid enters the refrigerating room to respectively provide heat and cold for cold drink and hot meal, the heat insulation boards between the refrigerating room and the heating room prevent heat exchange between the refrigerating room and the heating room, and the clamping grooves in the box body can change the position of the heat insulation boards, so that the size of the refrigerating room and the heating room is changed. The storage battery of the electric car can be used as a power supply at night or in rainy days.

The technical scheme has the advantages that: the cold food and the hot rice can be respectively placed in the refrigerating room and the heating room during meal delivery, and the cold food and the hot rice are kept at certain temperature by the principle of refrigerating and heating by the vortex tube, so that the food can keep delicious quality and taste in the long-distance and long-time meal delivery process in summer and winter. The top of takeaway case has solar photovoltaic power generation board, utilizes solar energy to act as the power daytime, and evening or the battery that utilizes the trolley-bus act as the power has energy-conserving advantage.

As a further improvement of the utility model, the thermal insulation material filled in the takeaway box body is made of high-density polyurethane fluorine-free foaming material.

The technical scheme has the advantages that: the high-density polyurethane fluorine-free foaming material has good heat insulation performance, so that the heat loss and the cold loss of the heat insulation box in the takeout distribution process are reduced.

As a further improvement, the top cover of the box body is connected with the box body through a hinge, and the top cover of the box body is provided with a sealing strip with the joint of the box body.

The technical scheme has the advantages that: the sealing strip is arranged, so that the box body is compact, and the sealing performance of the take-out box is improved.

As a further improvement, the inner wall of the box body is provided with at least two clamping grooves in the vertical direction.

The technical scheme has the advantages that: the position of the heat insulation plate can be changed through the clamping groove, so that the size of the refrigerating room and the heating room can be changed according to needs.

The utility model provides a but takeaway case of refrigeration and heating's beneficial effect lies in that this takeaway case adopts the battery as power supply mechanism, the battery can charge through external power plug, also can carry out the electric energy savings through the solar photovoltaic electricity generation board of installing at case lid top, it is sufficient to ensure battery power, can practice thrift the power consumption, play energy-concerving and environment-protective effect, can be L ED temperature monitor through the battery, temperature-sensing ware and compressor supply power, can real-time supervision takeaway incasement temperature and through installing the temperature-sensing ware real-time display on the case lid through temperature-sensing ware, make things convenient for the temperature of taking away case to master in time by the food delivery person, through the temperature of adjusting the takeaway case of flow control valve adjustment on the vortex tube, reduce the calorific loss of cold drink or hot meal in the food delivery process, guarantee the quality of food, satisfy the demand of people to the things.
