Efficient energy-saving stove

Abstract

The invention relates to an efficient energy-saving stove. The stove comprises an empty-burning preventing device, a waste heat recycling device and a burning optimizing control device. The empty-burning preventing device comprises a pan sensing device and a wok sensing device which are composed of non-contact type electromagnetic sensing sensors. The waste heat recycling device comprises a waste heat recycling part composed of a hearth recycling section, a horizontal recycling section and a vertical recycling section, and a waste heat utilizing part composed of a cold water heating box and a hot water tank. The hearth recycling section, the horizontal recycling section and the vertical recycling section are connected with the cold water heating box and form independent water heating circulation systems respectively. A pipeline is communicated between the cold water heating box and the hot water tank. The burning optimizing control device is composed of an opening degree detection device of a fuel gas pipeline valve, a controller and a draught fan speed regulating module. According to the efficient energy-saving stove, the empty-burning preventing effect is effectively improved, waste heat recycling efficiency and burning efficiency are effectively improved, and all-around energy conservation and consumption reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of stoves, and in particular relates to a high-efficiency and energy-saving stove. Background technique [0002] For the cooking stoves used in the catering industry, although the cooking stoves can be turned off during the intervals before and after cooking, such as side dishes, plate loading, and pot washing, etc., when no fire is needed, but during the peak period of passenger flow, the chefs are too busy. There is no time to turn off the fire. In addition, once the stove is turned off, it needs to be re-ignited and turned on to adjust the fire. For the catering work that races against time, the efficiency of serving food will be reduced. Therefore, the stove is often left to burn in vain, which wastes fuel. The temperature in the kitchen was raised again. At present, although there are many anti-air burning technologies in China, such as the use of infrared sensor switches to automatically ignite or tur...

[0002] For the cooking stoves used in the catering industry, although the cooking stoves can be turned off during the intervals before and after cooking, such as side dishes, plate loading, and pot washing, etc., when no fire is needed, but during the peak period of passenger flow, the chefs are too busy. There is no time to turn off the fire. In addition, once the stove is turned off, it needs to be re-ignited and turned on to adjust the fire. For the catering work that races against time, the efficiency of serving food will be reduced. Therefore, the stove is often left to burn in vain, which wastes fuel. raised the temperature in the kitchen

At present, although there are many anti-air burning technologies in China, such as the use of infrared sensor switches to automatically ignite or turn off the stove, but because the kitchen environment has high humidity and heavy oil pollution, the false alarm rate and failure rate are high, so that the stove The situation of burning in vain has not been effectively resolved, resulting in fuel waste and increased catering operating costs

[0003] Chinese patent document CN201680442U discloses a stove top with a pedal control device, the switch of the electromagnetic valve is controlled by the pedal, which reduces the failure rate caused by the induction system due to the poor kitchen environment; but because the chef is too busy cooking , there is basically no time to perform operations that require the cooperation of other limbs, so the practicality of this device is not high, and its theoretical effect cannot be achieved to achieve the purpose of energy saving

However, none of the above disclosed patent documents is designed for the overall waste heat of the stove to achieve full utilization, but only for the chimney and the furnace wall alone, which cannot achieve a high waste heat utilization efficiency
