Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] refer to figure 1 , 2 , 3, 4, 5, 6, 11, 12, 13, and 14, the present invention uses waste heat to preheat the energy-saving stove for premixed gas, including a stove pan 1, a flue gas guide hood 2, and an air duct bend Head 3, honeycomb porous ceramics 4, energy-gathering plate frame 5, burner 6 and mixing chamber 7, hob 1 is a hollow cylindrical pan with a hole in the middle, and the edge of hob 1 has a flange in contact with the pot. There are three bends in 1. The bottom of the furnace plate 1 communicates with the flue gas duct 2. The structure of the flue gas duct 2 is a circular table structure with a large upper part and a smaller bottom. The outer side of the lower part of the flue gas duct 2 There is an exhaust pipe, and the outlet of the exhaust pipe is connected to the tail of the cooker. The smoke guide cover 2 is ...

Abstract

The invention relates to an energy-saving stove preheating premixed combustible gas by using after heat. The stove comprise a stove plate, a burner and a mixing chamber, wherein the burner is arrange in the middle of the bottom of the stove plate, and the burner is communicated with the mixing chamber; the stove also comprises a fume guide hood for guiding fume after heat in the stove plate to the outer wall of the mixing chamber to preheat the premixed combustible gas in the mixing chamber; a flanged edge contacting with a cooker is arranged at the border of the stove plate; the fume guide hood is communicated with the bottom of the stove plate, and is sleeved outside the mixing chamber; the fume guide hood is in sealed connection with the outer wall of the mixing chamber at the bottom; the fume guide hood is provided with an after heat discharge outlet; and the stove plate is internally provided with cellular porous ceramic which is obliquely erected through an energy gathering plate bracket. According to the energy-saving stove provided by the invention, the traditional fume emission notch at the upper part of the stove plate is omitted, direct discharge of fume whose after heat is not utilized is reduced; and through arranging the mixing chamber in the fume guide hood, a preheating device and the stove form a whole body, and the purpose of preheating the premixed combustible gas delivered into the stove can be achieved without need of splitting for independent use.

Description

technical field [0001] The invention relates to a gas cooker, in particular to a high-efficiency and energy-saving commercial gas cooker that can make full use of waste heat. Background technique [0002] Currently commercial cookers generally require forced air supply, and the heat load is as high as 25KW-50KW, and most of the heat generated by the cooker is directly discharged to the outside world without being well utilized. Even if some existing cooking ranges are provided with devices for preheating air, the preheating devices belong to supporting devices used alone, and are not integrated with the cooking range itself. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving stove capable of preheating premixed gas by utilizing waste heat. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] An energy-...
