Energy-saving gas cooking stove

Abstract

The invention provides an energy-saving gas cooking stove. The cooking stove comprises a large gas-collecting hood, a small gas-collecting hood, a centrifugal blower, a high-temperature air preheater, a low-temperature hot water heater, a cooking stove burner, a furnace, a water pump, a cold water tank, a hot water tank, a pan, a chimney, etc. The small gas-collecting hood collects an oil smoke gas mixture generated in a cooking process, the centrifugal blower absorbs the gas mixture, the gas mixture is sent to the high-temperature air preheater, high temperature flue gas discharged from the furnace heats the gas mixture, the gas mixture returns to the cooking stove burner, and the gas mixture and gas are mixed for combustion. Energy feedback technology is used for recycling waste heat of the cooking stove, so that energy saving effect is realized. The low-temperature hot water heater is arranged behind the high-temperature air preheater for continuously recycling unexhausted heat in the flue gas and generating hot water which is used for kitchen. A small chimney is connected to the low-temperature hot water heater, so that flue gas is sent to a main chimney by the small chimney and discharged to atmosphere. The cooking stove employs the oil smoke gas mixture as a gas combustion improver instead of air, and high temperature combustion ensures elimination of components which are harmful for human body in the oil smoke gas mixture, so that kitchen environment conditions are improved.

Description

Technical field: [0001] The invention provides a gas energy-saving cooker. It belongs to the field of energy saving and can be applied in the kitchen of catering industry. Background technique: [0002] Kitchen energy saving is an important part of creating a green kitchen, and pot stove energy saving is the main task of kitchen energy saving. According to the provisions of the People's Republic of China's urban construction industry standard CJ / T392-2012 (cooking gas cooker), the thermal efficiency of cooking gas cooker is not less than 45%; according to the People's Republic of China urban construction industry standard CJT28-1999 (Chinese food According to the regulations of gas cooking stoves), the thermal efficiency of gas cooking stoves for Chinese food is not less than 20%. According to these specified data, the thermal efficiency of both the large gas cooker for cooking and the gas cooking stove for Chinese food is very low. More than half of the energy goes unuse...
