Abstract

A kind of multi-usable insulated bag that provided with heating and refrigerating function is disclosed in the present invention. The insulated bags heat or chill the water and the food in the backpack or satchel or handbag by using the energy in the battery or external direct supply. The bagy according to the present invention bring heat and cold produced from the electric heating film or PTC ceramic heating plate and semiconductor refrigerating plate to act the out wall of the water box or water cup and the food box, and then the insulated bags heat and chill the water or drink and the food in the box. The bags according to the present invention can thermal control the water and the food heated or chilled. The bags' circuit has short-circuit protection, over temperature protection, under-voltage protection or over-discharge protection of the battery. The bags according to the present invention can cut the power of the heating and the cooling circuit and protect the safe of the battery group and the whole circuit including the electric heating film and the semiconductor refrigerating plate. The bags according to the present invention can also remind the user by language or music when the value of under-voltage or over-discharge of the battery or the heating or the cooling temperature reaches set point. The outside of the insulated bag near the body back is set with a detectable wire frame with made from metal, plastic or nylon. The bags according to the present invention cold the user by heat sinking when the weather is hot.

Description

technical field [0001] The invention relates to electrical equipment, in particular to heat preservation equipment integrating heating and cooling, specifically a portable heat preservation bag with heating and cooling functions. Background technique [0002] In the prior art, the portable heat preservation bag has only water tanks (cups) and lunch boxes that heat or cool water or food independently, and they cannot be organically combined with various bags. It is not very convenient to carry and use, and the capacity of the portable water tank or lunch box is small, its function is single, it cannot be controlled by temperature regulation, and there are few or no protective devices. It cannot solve the over-temperature safety problem of heating and cooling devices, nor can it protect the battery from undervoltage, and cannot use language or music to remind certain functions and statuses, so it is not very practical. In addition, when the weather is hot, the human body feel...
