Multi-functional high-temperature efficient energy-saving steam oven

Abstract

The invention discloses a multi-functional high-temperature efficient energy-saving steam oven which comprises an oven body, a steam generator (31) and a burner (41). The oven body comprises an oven core wall (21), an oven core spinning nest (23) and a heat preservation wall (24). A burning included channel (234) is formed between inner sides of the oven core spinning nest (23) and the heat preservation wall (24). The heat preservation wall (24) is arranged outside the oven core wall (21), an annular smoke waste heat absorbing cavity (241) is formed, and the steam generator (31) is arranged in the smoke waste heat absorbing cavity (241). The burner (41) is arranged on the heat preservation wall (24) and the steam generator (31). The multi-functional high-temperature efficient energy-saving steam oven can achieve purposes of frying and steaming simultaneously, is high in temperature inside the oven and heat energy use rate, sufficient in burning and energy-saving, and reduces environment pollution.

Description

technical field [0001] The invention relates to a stove, which is a steam stove, in particular a multifunctional high-temperature, high-efficiency and energy-saving steam stove. Background technique [0002] The current fuel (oil, gas (coal gas, liquefied petroleum gas, natural gas) etc.) stove includes a stove core wall, the lower part of the stove core wall is provided with a flame inlet, the flame inlet is connected to the flame outlet of the burner, and the upper part of the stove core wall is provided with a smoke Gas outlet; when in use, the pot is located above the stove core wall, and the flame generated by the burner enters the inner cavity (ie, the hearth) of the stove core wall 1 from the flame inlet 11 at the lower part of the stove core wall, continues to burn, and then passes through the bottom of the pot , the generated flue gas is directly discharged from the flue gas outlet on the upper part of the furnace core wall. The current fuel stove core has the foll...

AI Technical Summary

Problems solved by technology

The current fuel stove core has the following disadvantages: 1. The flame moves from the flame inlet at the bottom of the stove core wall to the flue gas outlet at the top, and the flame basically advances in a straight line. Most of the heat of fuel combustion is quickly discharged from the flue gas outlet with the flue gas, and the heat utilization rate is very low; at the same time, because the flame travels in the furnace for a short time, the residence time is very short, the fuel cannot be fully mixed with oxygen, and the combustion is incomplete. Cause fuel waste and environmental pollution; 2. The inner side of the stove core wall is a smooth surface, the flame has a poor grilling effect on the stove core wall, the heat absorption rate of the stove core wall is not high, and the temperature of the stove core wall is not high, so that the temperature in the entire furnace is not high , low heat utilization

But it has the following disadvantages: 1. It only utilizes the heat transfer of the stove core wall, and the flue gas is not utilized. At the same time, because the stove core wall transfers heat to the outside with water, the temperature in the furnace will be reduced, resulting in insufficient combustion firepower; 2. The surface area of ​​the inner stainless steel annular plate is small, the heat transfer area is small, the heat utilization rate is low, and the waste heat collection effect is low (only about 20%); 3. It is not convenient for maintenance

[0004] Therefore, the current stove has a single function, and it is difficult to realize cooking and steaming at the same time through the heat of the same fuel combustion; the flame and smoke generated by the fuel combustion have a short journey in the stove, a short residence time, a low temperature in the stove, and an efficient heat utilization rate. Low; it is difficult to accurately and timely automatically adjust the ratio of air and oxygen, resulting in insufficient combustion and wasting energy
