Casting pig blank inner bag slow fire stewpot

Abstract

The invention discloses a cast iron billet inner shell slow cooker which comprises an outer casing, an aluminum liner body which is buckled on an upper cavity in the outer casing, a unit cast iron billet inner shell which is embedded in the inner cavity of the aluminum liner body, an inward concave cast iron type billet which is adopted by the inner core of the unit cast iron billet inner shell, at least a layer of enamel which is evenly painted on the whole outer surface of the cast iron type billet, and the smooth surface of the unit cast iron billet inner shell which is formed by the enamel through being baked. By adopting the iron liner cooker of the cast iron type billet, the overall fastness of the cooker body is effectively enhanced while the cooker surface is kept smooth, and the cooker body is uneasy to be broken into pieces; a lined annular handle support is in favor of enhancing the rigidity of the wall thickness of the outer casing and improving the service life of the whole cooker; the appearance of a controlling knob configured on the side part is elegant, and the operation is convenient; a rubber ring is configured at the seaming of the cooker cover, thereby improving the sealing performance of the cover, preventing the heat from leakage, and having better energy saving effect. The volume scope of the unit cast iron billet inner shell is 1.0 liter to 8.5 liters, and a model is respectively available for the spacing distance of 0.5 liters within the volume scope, thereby being convenient for diversification.

Description

technical field [0001] The invention relates to the technical field of an electric heating pot, in particular to a slow cooker with a cast iron billet liner. Background technique [0002] The current slow cooker in the society is covered with a porcelain pot in the aluminum tank, such as the Chinese utility model patent "Temperature Control Slow Cooker" (notification number CN2747996Y) whose patent number is ZL03245148.2; The slow cooker includes a porcelain pot, an aluminum liner and a temperature controller. A through hole is opened on the aluminum liner, and a heat insulating seat is installed on the through hole. The temperature controller is installed on the heat insulating seat and connected with the porcelain pot. Contact; when installing the thermostat, this design uses an auxiliary heat insulation seat, which complicates the assembly of the thermostat and brings inconvenience to maintenance; A heat insulation seat is embedded in the hole. The skin of the aluminum t...

[0002] The current slow cooker in the society is covered with a porcelain pot in the aluminum tank, such as the Chinese utility model patent "Temperature Control Slow Cooker" (notification number CN2747996Y) whose patent number is ZL03245148.2; The slow cooker includes a porcelain pot, an aluminum liner and a temperature controller. A through hole is opened on the aluminum liner, and a heat insulating seat is installed on the through hole. The temperature controller is installed on the heat insulating seat and connected with the porcelain pot. Contact; when installing the thermostat, this design uses an auxiliary heat insulation seat, which complicates the assembly of the thermostat and brings inconvenience to maintenance; A heat insulation seat is embedded in the hole. The skin of the aluminum tube is generally thin, and it is usually made by stamping. Generally, a stamping die must be made for stamping. Therefore, in the actual production of the aluminum tube, the cost is relatively low. Including the cost of stamping dies and the investment in equipment caused by the complexity of the stamping model; due to its high brittleness, porcelain pots may break if you are not careful during use, which will lead to the failure of the entire pot to be used normally; and Porcelain pots take a long time to heat up, and their thermal conductivity is not as good as that of iron products. In this way, part of the energy will increase during heating, which is not conducive to energy saving.
