Novel double-ring uniform-temperature bottom heating structure device

Abstract

The invention belongs to the field of kitchen appliances, and relates to a novel double-ring uniform-temperature bottom heating structure device which comprises an inner cavity, a uniform-temperature heat-conducting plate, an outer-ring heating pipe, an inner-ring heating pipe, a heating temperature-gathering plate and a heating pipe connecting plate, a water-gathering concave surface is arranged at the bottom of the inner cavity, a lower concave surface is arranged on the uniform-temperature heat-conducting plate, and a mounting groove is formed in the top of the heating temperature-gathering plate. An external interface is formed in the groove wall of the mounting groove; and the uniform-temperature heat-conducting plate is made of a metal heat-conducting material. The water gathering concave surface capable of gathering condensate water is arranged at the bottom of the inner cavity, steam condensate water is subjected to temperature gathering heating evaporation through cooperation of the inner ring heating pipe and the uniform-temperature heat conduction plate, high-temperature steam is generated again, energy consumption is reduced, the inner ring heating pipe is arranged in the heating temperature gathering plate in a hidden mode, and attractiveness is not affected; and the temperature of heating heat of the outer ring heating pipe and the inner ring heating pipe is uniformly distributed through the uniform-temperature heat conducting plate, so that a uniform temperature field is generated, and the condition that food is burnt or cooked or uncooked due to uneven temperature during food baking is avoided.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a novel double-ring uniform temperature bottom heating structure device. Background technique [0002] The steam oven appliance is a combination of steaming and roasting. The steaming and roasting functions of the steam oven are realized through the heating structures of the top heating tube, the rear heating tube, the bottom heating tube and the steam generator. When cooking with steam, due to the physical cold and heat effect in the inner cavity, there will be steam condensed water during the steam heating process, which will accumulate around the bottom of the inner cavity without accumulation of backflow. This type of appliance relies on the heating tube at the bottom to evaporate the condensed water at the bottom, but The heating area at the bottom is too large. Although there is heating, the condensed water cannot be boiled and evaporated. There is also a hole at the botto...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problem of how to quickly heat and evaporate the condensed water accumulated around the bottom of the inner cavity and how to make the baking temperature uniform at the bottom of the inner cavity, the present invention provides a new double-ring uniform temperature bottom The heating structure device has an inner ring heating tube and a uniform temperature heat conduction plate made of metal heat conduction material. The bottom of the inner cavity is provided with a water collecting concave surface that can collect steam condensed water, and the lower concave surface area is heated separately through the inner ring heating tube , through the uniform temperature conduction plate to the water-accumulating concave surface at the bottom of the inner cavity, thereby reducing the heating area, accumulating heat energy, heating and evaporating the steam condensed water gathered in the water-accumulating concave surface, and generating high-temperature steam again, reducing Energy consumption, the inner ring heating tube is hidden in the heating temperature gathering plate, which does not affect the appearance; through the uniform temperature heat conduction plate, the heating temperature of the outer ring heating tube and the inner ring heating tube are evenly distributed, thereby generating a uniform temperature field, Avoid the situation that the food is burnt or cooked or raw due to uneven temperature when the food is baked
