Problems solved by technology

[0003] There are two heating methods for the existing food delivery carts in hospital wards: the first is to inject steam directly into the cavity of the dining cart before delivery to condense it into water to heat the food. The water is not easy to collect, causing it to be spilled all the way during the meal delivery process; the second is electric heating tube heating, installing electric heating tubes in the dining car, this method heats up quickly, cools down quickly, and the holding time is short, often requiring secondary heating, which wastes electric energy. And limited by the distribution capacity

Abstract

The invention discloses a heat insulation dining car. According to the heat insulation dining car, a heat pipe is arranged in a vehicle box body and comprises a heating section and an isothermal section, the heating section and the isothermal section form a sealed loop, a steam heating pipe is arranged in the heating section, and the outer portion of the heating section is covered with an electric heating ring. The heat insulation dining car is simple in structure, works reliably, is small in overhaul amount and can improve heat transfer efficiency and heating speed, heat is released slowly, isothermality of the dining car is guaranteed, heat insulation time of the dining car is greatly improved, and the dining car does not overheat easily.

Description

technical field [0001] The invention relates to the technical field of food heat preservation, in particular to a heat preservation dining car. Background technique [0002] With the modernization of hospitals, inpatients have higher and higher requirements for nutritious meals. Nutritious meals are made by the nutritional canteen and delivered in a centralized manner. The temperature of the meals delivered to the wards is required to be kept above 60°C. At present, a modern tertiary hospital needs to deliver about 1,600 meals per meal. If calculated as 50 meals per dining car, 32 cars need to be loaded. Hospital nutrition canteens often pack and deliver meals after the meals are prepared. This process requires The time of about two hours, in this process, meal must be kept warm. [0003] There are two heating methods for the existing food delivery carts in hospital wards: the first is to inject steam directly into the cavity of the dining cart before delivery to condense ...
