Description
Technical field
The present invention relates to a kind of gas-cooker WHRS, belong to kitchen kitchenware technical field.
Background technology
According to statistics, existing catering trade gas-cooker is due to serious heat loss, and sky burns phenomenon generally, and its average thermal efficiency is only
20%, thermal loss is up to 80%, causes great energy waste.The thermal efficiency of so-called gas-cooker, is exactly generally to fire
The effective rate of utilization of gas kitchen in use to gas thermal energy.As can be seen that household gas range from the thermal efficiency of gas-cooker
Tool generally existing the not high phenomenon of gas thermal energy utilization rate, and the gas thermal energy for having about 40~50% is wasted in use.
Commercial gas kitchen range used on Vehicles Collected from Market, its combustion system still uses traditional open combustion system of malleation, combustion
In gas combustion process combustion flame and high-temperature flue gas are directly leaked so as to form a large amount of unburnt after fuel gas buring
High-carbon gas is directly discharged into surrounding environment, so that the heat that fuel gas buring is produced only has a small part to be utilized by pan,
Efficiency of utilization is extremely low.And due to that will bring atmosphere pollution and noise dirty in imperfect combustion combustion gas release and surrounding environment
Dye.Therefore, either household gas utensils or commercial gas kitchen range all suffer from energy significant wastage in use
Serious problems.
Following patent document is can be found that by the retrieval to gas-cooker recuperation of heat prior art：
Applicant Hefei Shunchang distributed energy comprehensive application technology Co., Ltd discloses a series of commercial gas pots and stoves
Fume waste heat retracting device, including retracting device, hot water supply system, unpowered recovery system etc., including shell, the shell
Inner vertical water inlet manifold and outfall sewer be installed, water inlet manifold is arranged on the right-hand member of shell, outfall sewer is arranged on
The left end of shell, the bottom of water inlet manifold, which is provided with the top of water inlet pipe, outfall sewer, is provided with outlet pipe, water inlet pipe and water outlet
Manually-operated gate is fitted with pipe, is provided with square finned tube, square finned tube and installs between water inlet manifold and outfall sewer
There is fin.But the configuration of its structure is complicated, inconvenience is controlled during use, it is inefficient, it is impossible to which that maximization effectively utilizes used heat
Energy.

1) without recuperation of heat Land use models：Such a situation occurs to catch fire the starting stage in gas-cooker, during shortage of heat, now without
Recuperation of heat need to be carried out.Concrete operations：The first three-way control valve K1 is adjusted for the first communicating position while adjusting the second threeway control
Valve K2 is the first communicating position, and now K1 is connected by the fluid conduits upstream 301 and first heat exchanger of first heat exchanger 201
Siphunculus road 302, while K2 connection first fluid loop pipes 303 (first heat exchanger bypass line 302) and fluid circuit house steward
307, and delivery heat transfer medium fluid is to waste heat fluid entrance 105.Thus, heat transferring medium fluid is circulated in pipeline only inhales
Receive used heat and carry out heat exchange without entering heat exchanger；
2) the normal Land use models of recuperation of heat：Such a situation occurs in gas-cooker normal work stage, and heat recovery is normal.Tool
Gymnastics is made：It is that the second three-way control valve K2 of regulation is the second connection position to the second communicating position simultaneously to adjust the first three-way control valve K1
Put, now, the fluid conduits upstream 301 and the entrance of first heat exchanger 201 of K1 connection first heat exchangers 201 prevent heat exchange
Medium fluid flows into bypass line 302, while K2 prevents first fluid loop pipe 303 (first heat exchanger bypass line 302)
With the connection of fluid circuit house steward 307, second fluid loop pipe 306 and the connection and conveying of fluid circuit house steward 307 is kept to change
Thermal medium fluid is to waste heat fluid entrance 105, and thus the fluid circulation of heat exchanging medium flow body formation is complete by two heat exchangers
The heating of paired inlet air and the storage of used heat are reclaimed；
3) the first heat exchange take-back model：Such a situation occurs needing to increase intake air temperature, improving combustion efficiency
When, it is necessary to close to the second heat exchange reclaim, with this increase to the first heat exchange reclaim utilization.Concrete operations：Regulation first
Three-way control valve K1 is that the second three-way control valve K2 of regulation is the first communicating position to the second communicating position simultaneously, now, K1 connections
The fluid conduits upstream 301 of first heat exchanger 201 and the entrance of first heat exchanger 201, prevent heat transferring medium fluid from flowing into other
Siphunculus road 302, while K2 connection first fluid loop pipes 303 (first heat exchanger bypass line 302) and fluid circuit house steward
307 and delivery heat transfer medium fluid arrives waste heat fluid entrance 105, the fluid circulation that thus heat exchanging medium flow body is formed is merely through the
One heat exchanger, completes the heating to inlet air；
4) the second heat exchange take-back model：Such a situation occurs when needing to carry out the storage of used heat Recovery of the hot water, now right
Fuel gas buring efficiency requirements are not high, when larger to Recovery of the hot water storage requirements, and the utilization reclaimed to the second heat exchange is increased with this.
Concrete operations：It is that the second three-way control valve K2 of regulation is the second connection to the first communicating position simultaneously to adjust the first three-way control valve K1
Position, the fluid conduits upstream 301 and first heat exchanger bypass line 302 of now K1 connections first heat exchanger 201, is realized
To the bypass of first heat exchanger, while K2 prevents first fluid loop pipe 303 (first heat exchanger bypass line 302) and stream
The connection of body loop house steward 307, keeps connection and delivery heat transfer of the second fluid loop pipe 306 with fluid circuit house steward 307 to be situated between
Mass flow body is completed to waste heat fluid entrance 105, the thus fluid circulation of heat exchanging medium flow body formation merely through second heat exchanger
Heating to storing cold water.
