Baking tray and oven

Abstract

The invention belongs to the field of household appliances, and discloses a baking tray and an oven, and the baking tray comprises: a hollow interlayer wall which is at least formed at the bottom of the baking tray and is internally provided with a hollow interlayer cavity; a liquid-gas phase change working medium which is positioned in the hollow interlayer cavity and can be converted into a gasstate from a liquid state when being heated to a phase change temperature; and an exhaust port which communicates with the hollow interlayer cavity so that the gaseous liquid-gas phase change workingmedium can be exhausted outwards. The baking tray disclosed by the invention can continuously transfer heat to the liquid-gas phase change working medium when the temperature rises so as to realize self-cooling; particularly, when the liquid-gas phase change working medium is heated to the phase change temperature and is changed from the liquid state to the gas state, mass heat is absorbed, the working medium temperature is maintained at a phase change temperature point; meanwhile, the surface temperature of the baking tray is maintained to be close to the phase change temperature, oil liquidon the baking tray can be effectively prevented from being vaporized into lampblack, the user experience is improved, the pressure in the hollow interlayer cavity can be kept stable by arranging the exhaust port, and when the liquid-gas phase change working medium is water, the water vapor can also achieve the humidifying and tender baking effects.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a baking pan and an oven. Background technique [0002] The operating temperature of the existing electric oven can reach 200° C. to 300° C. In this temperature range, the electric oven will generate a lot of oily smoke during the baking process. When there is a gap in the door of the electric oven or when the door is opened, the internal oil fume will leak out, thereby affecting human health. In addition, part of the oil fume will condense and adhere to the oven cover to form stubborn oil stains when it leaks out, which is not conducive to cleaning and maintenance. [0003] In the prior art, there are mainly two methods to solve the problem of large oil fume in the electric oven. The first is to turn on the range hood during the use of the electric oven. Although this solution can effectively reduce the amount of oil fume in the external environment, it is not esse...

Problems solved by technology

When there is a gap in the door of the electric oven or when the door is opened, the internal oil fume will leak out, which will affect human health

In addition, part of the oil fume will condense and adhere to the oven cover when it leaks out to form stubborn oil stains, which is not conducive to cleaning and maintenance

[0003] In the prior art, there are mainly two methods to solve the problem of large oil fume in the electric oven. The first is to turn on the range hood during the use of the electric oven. Although this solution can effectively reduce the amount of oil fume in the external environment, it is not essential Solve the problem of oil fume leakage, so the phenomenon of stubborn oil stains on the oven cover still exists

The second is to reduce the generation of oily smoke by lowering the operating temperature of the electric oven, but the lowering of the operating temperature will cause the cooking time to be longer, so it will more or less have an adverse effect on the cooking effect
