Description
Technical field
The present invention relates to a kind of steaming or cooking device, relate in particular to a kind of fuel gas heating and cooking device that is used for the boiling wheaten food.
Background technology
The wheaten food boiling equipment (with reference to Fig. 1,2) that uses mainly is made up of the container 1 that is filled with water, flue 2, base 3, magnetic valve 4, Gas Pipe 5, fire row 6, hand-operated valve 7, interchanger casing 8, stainless steel tube 9 (or heat collecting sheet 11) and tap 10 at present.See Fig. 1 and Fig. 2 for details.
Hand-operated valve 7 is opened, and water injects container 1 by tap 10; Open magnetic valve 4 then, combustion gas, takes fire after lighting from fire row 6 ejections by Gas Pipe 5, and high-temperature flue gas is discharged from flue 2 through heat exchanger, thus the water in the heating container 1.
But, owing to inject the water of container 1, normally without the softening running water of handling, hardness of water is higher, along with the rising of water temperature, container 1, interchanger casing 8 and stainless steel tube 9 will produce incrustation scale with the water contact portion, and the incrustation scale in the stainless steel tube 9 is difficult to cleaning, and along with the increase of incrustation scale thickness, the efficient of heat exchange descends thereupon, and the serious place of fouling very easily causes heat exchanger cracking to occur, leak because of heat exchange difference temperature can sharply raise; If crackle appears at the weld of interchanger casing 8 and stainless steel tube 9, then extremely difficult soldering causes whole heat exchanger to be scrapped.
In order to improve effectiveness of heat exchanger, heat exchanger is arranged in the water container 1, and the water between the wall of heat exchanger and container 1 mainly is to be used to conduct the heat that heat exchanger wall absorbs, but not cooking technology the water that must use, this part water accounts for about 20% of Total Water in the container 1 usually; Obviously, only, this part water heating is undoubtedly a kind of energy waste from satisfying the water of food cooking technology requirement.For the water yield that reduces only to be used in the container 1 to conduct heat, the space is all less (usually≤45mm) between the wall of heat exchanger and container 1, thereby, the bottom of container 1 and heat exchanger are in the bottom of exhaust opening in the container 1, water (dirt) dirt is easy cleaning not, be unfavorable for food hygiene, and reduced the efficient of heat exchanger.
In addition, for commerce equipment, except that require energy-conservation, the heating rate of water in the time of also will considering to heat.Because stainless thermal conductivity lower (about 15.2W/ (mK)), the heat that heat exchanger can not be arranged fire 6 high-temperature flue gas that produce in time passes to the water in the container 1, the flue-gas temperature that causes flue 2 to discharge higher (common 〉=130 ℃), thereby device heat efficiency is lower.
Summary of the invention
The invention provides a kind of can augmentation of heat transfer, be convenient to clean and help cutting down the consumption of energy, improve the fuel gas heating and cooking device of the thermal efficiency.
The present invention adopts following technical scheme:
A kind of fuel gas heating and cooking device comprises container, is communicated in tap, base, exhaust gases passes and the combustion system of water pipe.Tap is located at the top of container, container is positioned at the top of base, combustion system comprises igniter, magnetic valve, fire row and the Gas Pipe that is connected with fire row, exhaust gases passes comprises that heat insulation layer and exhaust gases passes are made of the outer wall and the heat insulation layer of container, fire row is located at the below of container and is offset to the below of container one side, and the flue gas population of exhaust gases passes and fire are arranged relative and exhaust gases passes extends to container along container outer wall from a side of container opposite side.
Compared with prior art, the present invention has following advantage:
1. the exhaust gases passes among the present invention is made of the outer wall and the heat insulation layer of container, the smoke inlet of fire row and exhaust gases passes is offset to the i.e. selection of the ad-hoc location of " fire row and flue gas population " of container one side, exhaust gases passes is extended along container outer wall, form bigger heat exchange area, thereby strengthened heat transfer, helped cutting down the consumption of energy, improving the thermal efficiency.
After the present invention adopts heat collector, though can increase heat exchange area, also increase the resistance of flow of flue gas, the flue gas air deflector guides then or forces more that thickness gas advances the outer wall area that the people is provided with the heat collector container, thereby augmentation of heat transfer has strengthened the heat exchange effect; Especially flue gas air deflector of the present invention has adopted the flue gas flow deflector, the flue gas flow deflector stands on the heat insulation layer and after the flow direction inclination technical measures of flue gas, not only augmentation of heat transfer, strengthen the heat exchange effect, and stoped flue gas to deviate from heat collector and built up to the place of delivering of exhaust gases passes, therefore, flue gas flow deflector and heat collector are supported mutually, are interacted, and improve heat exchange efficiency.After adopting the heat collector that constitutes by arrangement in a row and the red copper heat collecting sheet that is interspersed as the present invention, this technical characterictic and flue gas flow deflector and specific mutual support the in " fire row and smoke inlet " position (that is: the fiery below that is offset to container one side of arranging), further augmentation of heat transfer, enhancing heat exchange effect, raising heat exchange efficiency.
2. the present invention has further taked the technical measures of " water tank being set on exhaust gases passes; tap is communicated in water pipe by water tank ", especially after having adopted " water tank is a toroidal container; the interior ring surface at toroidal container is provided with heat collector " technical measures, made full use of the waste heat of flue gas, help energy-conservation and cut down the consumption of energy, thereby further improve heat exchange efficiency.
Table 1 is that existing equipment (adopting Fig. 4 heat collector) compares with energy consumption of the present invention.
