Abstract
The invention provides a high-efficiency energy-saving commercial cooking hearth which is small in size, light in weight and good in fire resistance. The combustion smoke exhausted by the cooking hearth cannot influence the heating efficiency of a cooking stove, and besides, the temperature of the combustion smoke is low, so that the heat radiation of the combustion smoke to surroundings is small, and the cooking hearth is high-efficiency, energy-saving and environment-friendly. The high-efficiency energy-saving commercial cooking hearth comprises a combustion-smoke guiding cover (1), a hearth cavity (2), a connecting bracket (3) and a combustion-smoke exhausting opening (4), wherein the hearth cavity (2) is arranged at the periphery of the combustion-smoke guiding cover (1) in a sleeving manner; an interlayer is formed between the hearth cavity (2) and the combustion-smoke guiding cover (1), and communicated with the combustion-smoke exhausting opening (4) and a combustion-smoke exhausting opening (6); the combustion-smoke guiding cover (1) and the hearth cavity (2) are made of steel and adopt an annular cylindrical structure; through the connecting bracket (3), the combustion-smoke guiding cover (1) and the hearth cavity (2) are fixedly connected to form a whole; mounting holes for being fixedly connected with a combustor of the commercial cooking stove are formed in the connecting bracket (3).
Description
Technical field
The present invention relates to a kind of vitals of commercial stove, specifically refer to a kind of energy-efficient commercial oven hearth.
Background technology
Commercial stove is as the term suggests refer to the cooking stove being applied in commercial kitchen, as the places such as commercial kitchen such as restaurant, restaurant, factory, universities and colleges, office, army, enterprises and institutions, train, steamer of catering industry.Commercial stove due to its frequency of utilization high more than home furnace, and once go wrong, the impact caused is also large than home furnace.So all parts of commercial stove all must have quite high reliability, particularly burner hearth part; Burner hearth is an important component part of commercial stove, and burner hearth is surrounded by furnace wall the solid space supplying fuel combustion.The effect of burner hearth ensures that fuel burns as much as possible, and the temperature making flue gas temperature of hearth outlet be cooled to convection heating surface trouble free service to allow.For this reason, burner hearth should have enough spaces, and arranges enough heating surfaces.In addition, rational shape and size should be had so that and burner coordinate, organize Furnace Aerodynamic Field, make flame not adherent, do not rush wall, degree of filling is high, wall thermic load is even.
In prior art, the structure that what commercial stove mainly adopted is as shown in Figure 1, it mainly comprises refractory burner hearth 01, encloses platform height side 02, fire clay 03, enclose platform downside 04, cast iron cooker racks 05, combustion product gases floss hole 06 and commercial burner 07; Described commercial burner 07 is installed on the inside of energy-efficient commercial oven hearth, the top of commercial burner 07 is provided with refractory burner hearth 01, the upper end of refractory burner hearth 01 is connected with encloses platform, enclose in platform and be filled with fire clay 03, enclose platform and be provided with cast iron cooker racks 05, the described platform that encloses is divided into and encloses platform height side 02 and enclose platform downside 04, at the bottom place of refractory burner hearth 01, is positioned at the side of enclosing platform height side 02 and offers combustion product gases floss hole 06.During concrete use, described frying pan 08 is positioned over cast iron cooker racks 05 and heats.Wherein, refractory burner hearth uses preformed refractory material or fire clay to be made.
The inventor of patent of the present invention often puts into practice, the commercial stove finding said structure in use its chamber structure has the following disadvantages: 1, volume is large, structure bulky, the burner hearth that refractory material makes because of the strength of materials not high, so increasing wall thickness, the weight of whole burner hearth is increased greatly.2, owing to being placed at frying pan after in cast iron cooker racks, the outlet at top is closed substantially, so combustion flame and high-temperature flue gas can due to top seals, under the effect that internal pressure increases, discharge from the exhaust opening of bottom sides, and not exclusively through the frying pan the bottom of a pan above, then making frying pan can not fully and burned flame and smoke contacts, the thermal efficiency is affected and reduces.The flue gas of 3, discharging from the exhaust opening of burner hearth bottom side is not owing to having sufficient heat exchange, and flue-gas temperature is high, easily produces the problems such as high temperature scald.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of volume little, quality is light, fire resistance is good, and the discharge of combustion product gases can not have influence on the efficiency of heating surface of cooking stove, and the flue-gas temperature of simultaneously discharging is low, little to periphery heat radiation, the energy-efficient commercial oven hearth of energy-conserving and environment-protective more.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of energy-efficient commercial oven hearth, and it comprises combustion product gases kuppe, burner hearth cavity, connection bracket and combustion product gases floss hole; Described burner hearth cavity is enclosed within the periphery of combustion product gases kuppe, and be provided with interlayer between described burner hearth cavity and combustion product gases kuppe, described interlayer is communicated with combustion product gases floss hole, described combustion product gases floss hole; Described combustion product gases kuppe and burner hearth cavity are the annular tubular structure of steel; Combustion product gases kuppe is fixedly connected with as a whole with burner hearth cavity by described connection bracket; Described connection bracket is provided with the installing hole for being fixedly connected with the burner of commercial stove.
As preferably, described combustion product gases kuppe is added is provided with cast iron cooker racks; Gap area between described combustion product gases kuppe and cast iron cooker racks is 1 ~ 2.5 times of the sectional area of combustion product gases floss hole.
As preferably, between the top of described combustion product gases kuppe and the bottom of cast iron cooker racks, be provided with the overlap distance of 3 ~ 15mm.
As preferably, described connection bracket is removable connection with between combustion product gases kuppe and burner hearth cavity.
