Description

一种余热回收高效节能灶具系统Waste heat recovery high-efficiency energy-saving cooker system 技术领域Technical field
本发明涉及一种厨房灶具,具体涉及一种余热回收高效节能灶具系统。The invention relates to a kitchen stove, in particular to a waste heat recovery high-efficiency energy-saving cooker system.
背景技术Background technique
现有的灶具设有灶体、燃烧室、与燃烧室连通的进风管和进气管,空气通过进风管进入燃烧室,燃气通过进气管进入燃烧室,燃烧室配设有点火系统,点火系统点燃产生热能,燃烧产生的火焰与锅体底部接触将热量传递给锅具。这种结构的灶具技术成熟,结构简单,也因此得到了广泛的应用。但是,火焰的温度外焰最高,而火焰与锅底换热后的温度较高的烟气直接排放掉了,未能经过二次利用直接通过烟道排向室外,热量的利用率相对较低,明显的表征就是夏天的食堂或者餐厅的厨房厨师天天都在“蒸桑拿”。可见这种结构的灶具不仅热能损耗严重,而且不利于厨房环境的维护。同时,这种结构的灶具的燃气消耗量大,直接通入空气燃烧效率低,燃烧不充分。The existing cooker is provided with a cooker, a combustion chamber, an air inlet pipe and an intake pipe communicating with the combustion chamber, the air enters the combustion chamber through the air inlet pipe, the gas enters the combustion chamber through the intake pipe, and the combustion chamber is provided with an ignition system, and the ignition The system ignites to generate heat, and the flame produced by the combustion contacts the bottom of the pot to transfer heat to the pot. The cooker of this structure is mature in technology and simple in structure, and thus has been widely used. However, the temperature of the flame is the highest outside flame, and the flue gas with higher temperature after the heat exchange between the flame and the bottom of the pot is directly discharged, and is not directly discharged to the outside through the flue through secondary use, and the heat utilization rate is relatively low. The obvious characterization is that the kitchen chef in the summer canteen or restaurant is in the "sauna" every day. It can be seen that the cooker of this structure not only has serious heat loss, but also is not conducive to the maintenance of the kitchen environment. At the same time, the gas stove of this structure has a large gas consumption, and the direct combustion air is low in combustion efficiency and insufficient in combustion.
同时在食堂或者餐厅等大厨房中,用于清洗、用于烹饪的热水需求量非常大,现有的食堂或者餐厅厨房通常都需要准备热水备用。如何设计灶体能够充分利用燃烧室产生的热气,以及减少烟气带走的热能损耗并充分利用烟气中的热量,提高燃气等的燃烧效率,成为灶具当前亟待解决的问题。At the same time, in large kitchens such as cafeterias or restaurants, the demand for hot water for cleaning and cooking is very high, and existing canteens or restaurant kitchens usually need to prepare hot water for use. How to design the stove body can make full use of the hot gas generated by the combustion chamber, reduce the heat energy loss taken by the flue gas and make full use of the heat in the flue gas to improve the combustion efficiency of the gas, etc., which has become an urgent problem to be solved in the cooker.
技术问题technical problem
可见现有结构的灶具,在使用时,灶具产生的热能因为开放式的结构造成严重浪费,燃气损耗大,造成厨房温度过高,影响厨房环境的舒适性。It can be seen that the cookware of the existing structure, when used, the heat energy generated by the cooker is seriously wasted due to the open structure, the gas loss is large, and the kitchen temperature is too high, which affects the comfort of the kitchen environment.
另外,在食堂或者餐厅等大型厨房中,需要清洗、需要用于烹饪的热水需求量非常大,现有的大型厨房通常都需要准备热水备用,一般都需要另外配备电热或燃气热水器,因热水需求耗能严重。In addition, in large kitchens such as canteens or restaurants, the amount of hot water that needs to be cleaned and used for cooking is very large.
