Abstract

The utility model relates to a high efficient energy saving gas range, which comprises a range body, a pot table, a lighter, a gas delivery pipe and a spray head. The gas inlet end of the spray head is connected with the gas delivery pipe, and the gas outlet end is a free end, and the spray head is positioned on the range body, and is provided with a pot table part. The spray head has two structural forms of a direct spraying type, and a spiral spraying type. The gas can be sprayed out in high speed after entering the spray head through the gas delivery pipe, and can be dispersed in high speed to form a combustion surface, and thus the flame is combusted by tightly contacting with the bottom of a pot. Because the combustion mode of the utility model is different form the existing gas range, the energy saving rate can obtain more than 30 percents. Furthermore, the structure can be simplified, and the production cost of the gas range can reduce about 15 percents.

Description

Efficiency energy saving gas range

The utility model belongs to kitchen range, and particularly a kind of is the kitchen range of fuel with fuel gas such as natural gas, oil liquefied gas.

Existing gas kitchen ranges is of a great variety, differ from one another, but its combustion system all is that by appendix combustion gas to be imported volume big and offer in the combustion chamber of some fire holes, combustion gas is burnt between the bottom of combustion chamber and pot, so only some flame directly acts on the bottom of a pan, cause partial heat energy to be wasted, thereby reduced rate of energy.

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of jet-propelled kitchen range are provided, to change the combustion system of combustion gas, energy savings.

The purpose of this utility model is achieved in that the combustion chamber of removing existing gas kitchen ranges, according to the design of the jet current principle in hydrodynamics gas spray head, makes gas flame press close to the bottom of a pan burning fully, thereby improves rate of energy.

The gas-cooker of realizing the utility model purpose comprises stove, the kitchen sink, ignition device, appendix and shower nozzle, and the inlet end of shower nozzle links to each other with appendix, and its outlet side is a free end, is positioned at stove and is provided with kitchen sink place.In order to guarantee best fired state, the spacing of shower nozzle outlet side end face and pot bottom part should be controlled at 30～40 millimeters.

The gas-cooker that the utility model provides, its shower nozzle have two kinds of versions, and a kind of is direct injection, and a kind of is rotary ejection type.The direct injection shower nozzle is the cylinder that the centre offers combustion gas hand-hole, acceleration hole and combustion gas discharge port, quickens the hole between combustion gas hand-hole and combustion gas discharge port, and its aperture is less than the aperture of combustion gas hand-hole and combustion gas discharge port; In order to make combustion efficiency better, can near the combustion gas discharge port hole wall that quickens the hole, offer the air entrance hole.The rotary ejection type shower nozzle is made up of sprayer body, dividing plate, pressure ring and nozzle cap; The sprayer body centre offers air admission hole and forms the shoulder hole of air chamber, and the aperture of air admission hole is less than the aperture of air chamber shoulder hole; Thereby having combustion gas on the dividing plate revolves the hole and is installed in and form upper chamber and lower chamber on the ladder of air chamber shoulder hole; Pressure ring is positioned on the dividing plate; The centre of nozzle cap offers the fumarole of aperture much smaller than upper chamber and lower chamber aperture, topped air chamber end during assembling at sprayer body, with the connected mode of sprayer body be sealed being connected.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Below by embodiment structure of the present utility model is described further.

Embodiment 1:

The structure of the gas-cooker in the present embodiment as shown in Figure 1 and Figure 2, its member comprises stove 1, the kitchen sink 5, ignition device 4, appendix 3 and shower nozzle 2.The kitchen sink is two, be positioned at that stove supports and upper surface; The ignition device switch of each kitchen sink correspondence is installed in the side of stove; Each kitchen sink is provided with shower nozzle, and the inlet end of shower nozzle and the connected mode of appendix are welding, and the outlet side is a free end, and the spacing of its end face and pot bottom part is 35 millimeters.The structure of shower nozzle 2 as shown in Figure 3, offer the cylinder of combustion gas hand-hole 6, acceleration hole 7 and combustion gas discharge port 8 for the centre, quicken the hole between combustion gas hand-hole and combustion gas discharge port, the aperture in each hole is respectively: 3 millimeters of combustion gas hand-holes, 2 millimeters in hole of acceleration, 5 millimeters of combustion gas discharge ports, the material of making shower nozzle is brass H62.

Embodiment 2:

The structure of the gas-cooker in the present embodiment as shown in Figure 1 and Figure 2, its assembling, connected mode of forming member and each member is with embodiment 1.Difference from Example 1 is the structure of shower nozzle, and the shower nozzle in the present embodiment offers four air entrance holes 9 as shown in Figure 4 on the hole wall near the combustion gas discharge port 8 that quickens the hole.

Embodiment 3:

The structure of the gas-cooker in the present embodiment as shown in Figure 1 and Figure 2, its assembling, connected mode of forming member and each member is with embodiment 1.Difference from Example 1 is that shower nozzle selects the rotary ejection type shower nozzle for use, and its structure such as Fig. 5, shown in Figure 6 are made up of sprayer body 10, dividing plate 13, pressure ring 14 and nozzle cap 16.The sprayer body centre offers air admission hole 11 and forms the shoulder hole of air chamber, and the aperture of air admission hole is 1.5 millimeters, and the aperture that forms the shoulder hole of lower chamber 12 is 12 millimeters, and the aperture that forms the shoulder hole of upper chamber 15 is 16 millimeters; Have two combustion gas on the dividing plate and revolve hole 18 and be installed on the ladder of air chamber shoulder hole, thereby form upper chamber 15 and lower chamber 12, combustion gas is after air admission hole 11, lower chamber 12 enter upper chamber, because combustion gas is revolved acting on of hole 18 and formed eddy flow in the upper chamber; For stationary barrier, make the volume of lower chamber stable, pressure ring 14 is positioned on the dividing plate, after the topped upper nozzle lid of the air chamber end of sprayer body and welding are connected, has both realized the fixing of dividing plate, has avoided the leakage of combustion gas again; The centre of nozzle cap has 1.5 millimeters fumarole, and the quick 360 ° of distributions of energy after the combustion gas of rotational flow sprays by this hole in the upper chamber form combustion front in the bottom of a pan, make flame be close to the bottom of a pan burning.

Compare with existing gas kitchen ranges, the utlity model has following advantage:

1. energy-saving effect is remarkable, and fractional energy savings can reach more than 30%.
