Abstract

The utility model discloses an oil or gas fired energy-saving cooking range, which comprises a cooking bench, a hearth and a burner. Top surface of the hearth corresponds to a boiler bottom above it, and support edge of the hearth top is a little higher than the top surface, thus leaving small space between the boiler bottom and the hearth top surface, and gaps are arranged on the support edge. In this structure, the hearth is closer to the boiler bottom, making flame spray upward between the boiler bottom and the hearth, and smoke produced be discharged from the gaps. As no tail gas hole is arranged in the hearth, the burner becomes closer to the boiler bottom, which improves heat efficiency and saves fuel by 30 per cent to 40 per cent. Therefore, the utility model has remarkable energy conservation effect and high spreading value.

Description

The fuel-firing gas-firing energy-saving kitchen range

Technical field

The utility model relates to the fuel-firing gas-firing energy-saving kitchen range.

Background technology

At the kitchen range equipment that catering industry uses, its structure mostly as shown in Figure 1, burner hearth 2 spaces are bigger, make and maintain suitable distance between the combustion furnace 1 and the bottom of a pan, have tail gas hole 4 simultaneously and connect toward flues 5 on hearth wall.This structure only is suitable for the kitchen range of the bottom lock that old-fashioned block does in fact, constantly the replenishing and the discharging of imperfect combustion flue gas of the required oxygen that is beneficial to burn.And present kitchen range have nearly all adopted special-purpose oil, gas firing stove, it is more abundant to burn, and smoke exhaust is arranged all in the kitchen, stove fire burning in the kitchen range that its fired state and old-fashioned block are done has had very big difference, if follow the design philosophy of " fire is hollow " again, then make a large amount of thermal-flames from tail gas hole, smoke stack emission, not only cause very big waste, the working environment around also having influenced simultaneously.

The utility model content

The purpose of this utility model is the fuel-firing gas-firing energy-saving kitchen range that a kind of heat utilization ratio height are provided, obvious energy saving effect is arranged.

The utility model comprises the kitchen range top, burner hearth, combustion furnace, and the end face shape of burner hearth and the bottom of a pan of top are suitable, and the support edge of roof of the furnace slightly exceeds end face, makes to keep less clearance between the bottom of a pan and the burner hearth end face, has breach simultaneously on the support edge.

In the utility model structure, burner hearth is more pressed close to the bottom of a pan, force flame in the gap of the bottom of a pan and burner hearth on spray, a small amount of flue gas of generation is discharged from breach topmost.Because no longer be provided with the tail gas hole in the burner hearth, the distance in the combustion furnace and the bottom of a pan is also corresponding approaching, the heat high concentration is in the bottom of a pan, increased heat exchange area, experiment showed, adopt this structure after, when heat was imitated raising greatly, energy fuel savings 30%～40% had reached obvious energy-saving effect.

The specific embodiment

Shown in accompanying

drawing

2,3, the utility model comprises the kitchen range top, burner hearth 2, combustion furnace 1, the end face shape of burner hearth and the bottom of a pan of top frying pan 3 are suitable, the support edge 2.1 of roof of the furnace slightly exceeds end face, make and on the support edge, have some breach 2.4 simultaneously in the gap that keeps 10～50mm between the bottom of a pan and the burner hearth end face.Support edge 2.1 has the effect of enclosing fire concurrently, breach the discharging that has made things convenient for flue gas is set.

Burner hearth 2 has two-layer up and down, and bottom 2.3 is an aludip, and upper strata 2.2 is refractory materials such as fire clay, the performance and the service life that have strengthened burner hearth.Support edge 2.1 can be one-body molded on this upper strata, also can be the pig iron and cast.

Claims

1, a kind of fuel-firing gas-firing energy-saving kitchen range, comprise the kitchen range top, burner hearth (2), combustion furnace (1), the end face shape of burner hearth and the bottom of a pan of top are suitable, it is characterized in that: the support edge of roof of the furnace (2.1) slightly exceed end face, make to keep less clearance between the bottom of a pan and the burner hearth end face, on the support edge, have breach (2.4) simultaneously.

2, fuel-firing gas-firing energy-saving kitchen range according to claim 1 is characterized in that: the gap between the described the bottom of a pan and the burner hearth end face is 10～50mm.

3, fuel-firing gas-firing energy-saving kitchen range according to claim 1 is characterized in that: burner hearth (2) has two-layer up and down, and bottom (2.3) is an aludip, and upper strata (2.2) are refractory materials such as fire clay, and support edge (2.1) can be one-body molded with upper strata (2.2).
