Description

The double grate radiator of cooking a meal

The utility model belongs to home furnace, particularly the double grate radiator of cooking a meal.

Existing household cooking and warming stove is provided with the water jacket of import water and delivery port at the burner hearth place, utilize cooking to realize heating with the recirculated water among the waste heat heating water jacket of fire, outside the deficiency, the required firepower of cooking is little, and it is little to be used for the area of the recirculated water heating among the heating water jacket, and temperature is low, the thermal efficiency is low, the discrepancy in elevation of existing in addition heating-cooking stove delivery port and water inlet is little, and the hot water in the water jacket is the weak effect of circulation automatically, and the fuel that uses is single.

The purpose of this utility model is to provide a kind of double grate radiator of cooking a meal, and not only can solve the cooking different firepower required with heating, improves the thermal efficiency, and heating hot water circulation effective automatically, both can burn coal, can burn faggot again.

This reality and the novel double grate radiator of cooking a meal that is achieved in that are made up of body of heater, fire door, water jacket and chimney, body of heater is separated into combustion chamber and ventilation dedusting chamber, the two side and the rear wall of combustion chamber are provided with water jacket, be provided with on top, combustion chamber and extend into the fireproof water sleeve that is communicated with the furnace wall water jacket in the combustion chamber, on the chimney wall, be wrapped in chimney water sleeve, be provided with the blast chamber of upper fire-grating on the top of combustion chamber, be provided with lower fire grating in its underpart, water inlet is positioned at the bottom of rear wall water jacket, and delivery port is positioned at the top of chimney water sleeve.

This utility model can be regulated the use firepower with the different needs of cooking according to heating owing to adopted double grate, and during heating, fuel burns on lower fire grating, and when cooking, fuel burns on upper fire-grating.Extend into fireproof water sleeve in the combustion chamber and increased the heating surface area of the radiator water jacket of cooking a meal, improved the thermal efficiency, the discrepancy in elevation of water inlet and delivery port is big, and heating hot water is circulation effective automatically.

Fig. 1 is the cook a meal profile of radiator of double grate, and Fig. 2 is the cook a meal vertical view of radiator of double grate.

Below in conjunction with accompanying drawing the utility model is further described, double grate is cooked a meal radiator by body of heater, fire door, water jacket and chimney are formed, body of heater is separated into combustion chamber (4) and dust removal by ventilation chamber (12) by the dividing plate that lower fire grating (13) is installed with body of heater, the water jacket that the two side of combustion chamber (4) and rear wall are provided with connection, be communicated with the fireproof water sleeve (3) that extend in the combustion chamber (4) on the top of combustion chamber (4) rear wall water jacket, fireproof water sleeve (3) also is communicated with the two side water jacket, the shape of cross section of fireproof water sleeve (3) is trapezoidal, its end of stretching in the combustion chamber (4) is a small end, on chimney (1) wall, be wrapped in chimney water sleeve (2), the top of (4) is provided with the blast chamber (8) of upper fire-grating (5) in the combustion chamber, in blast chamber (8), feed airduct (6), the bottom activity of being equipped with of blast chamber (8) is taken out and is pulled (9), the upper fire-grating area is little, firepower is violent, near from pot, can satisfy family's cooking with fiery, lower fire grating (13) is installed in the rear lower of combustion chamber (4), and preceding high back is low, tilt to install, lower fire grating (13) and 5 °-15 ° of horizontal angles, airduct (6) also is installed on lower fire grating (13), because lower fire grating (13) is installed in the rear lower of combustion chamber (13), burner hearth is deep and preceding high back is low, burns coal or burn faggot all very convenient.Water inlet (14) is positioned at the bottom of rear wall water jacket, delivery port (15) is positioned at the top of chimney water sleeve (2), the leading flank of (4) housing is equipped with upper furnace door (7) and lower furnace door (10) in the combustion chamber, leading flank at ventilation dedusting chamber (12) housing is equipped with dust removal by ventilation door (11), and stove circle (16) is installed on the end face of combustion chamber (4) housing.
