Abstract

The utility model relates to a domestic multifunctional water heater, which is suitable for cooking and supplying hot water in families and organizations. The utility model comprises a water heater composed of a housing, a hot water container provided with a water inlet and a water outlet, a hearth, and a smoke flue. The smoke flue is a fork-shaped bend pipe flue penetrating through the hot water container, the lower end thereof is communicated with the top part of the center of the hearth, and the middle part thereof is bent and is bifurcated into two branch smoke pipes; the upper ends of the two branch smoke pipes are connected to the outside from the side wall of the hot water container. The utility model can keep a comparatively small width of the housing to be matched with kitchen ware, and water can be heated up at a comparatively high speed; the exhaust of smoke is smooth, and the heat efficiency is comparatively high.

Description

The multifunctional domestic water heater

The utility model relates to the multifunctional domestic water heater that a kind of family and unit cooking and heat supply water use.

The applicant filed an application on February 24th, 1997 and on August 5th, 1997, and the patent No. is respectively 972065970.0 and 97235190.6, and title is two utility models of " multifunctional domestic water heater ", hot water can be provided and be used for cooking.And the number of patent application of filing an application on January 21st, 1998 is 98223110.5, and title still is the utility model of " multifunctional domestic water heater ", wherein adopts the bent-tube boiler flue, has dwindled outer casing width, reaches the purpose supporting with kitchen tools.But the single bent-tube boiler flue of this utility model is slower to the heat temperature raising of water, and the smoke evacuation of single port exhaust opening is evenly smooth and easy inadequately.

The purpose of this utility model is to provide a kind of improved multifunctional domestic water heater, still can keep less outer casing width and supporting with kitchen tools, and can be faster to water heat temperature raising and even smooth and easy smoke evacuation.

For achieving the above object, the utility model adopts following technical proposals: the utility model is the same with prior art to include a water heater that is made of shell, the hot water tank that water inlet and delivery port are arranged, burner hearth and flue.It is characterized in that flue is the fork-shaped bend pipe flue that passes the hot water tank inner chamber, top, burner hearth center is connected in its lower end, and its middle part beginning is crooked and be branched into two branch smoking pipes, and two branch smoking pipe upper ends pick out from the hot water tank sidewall.Because having adopted has the fork-shaped of two branch smoking pipes bend pipe flue, has increased the heat exchange area of flue and water, thereby can be fast to the water heat temperature raising; And fork-shaped bend pipe flue discharged fume by two branch smoking pipes, can more even smooth and easy smoke evacuation.

In can be designed as, fork-shaped bend pipe flue of the present utility model is provided with the damping baffle plate that increases flue gas stream turbulence level.This damping baffle plate can be designed as along fork-shaped bend pipe flue center lath is set, and the little floor that is staggered in these lath both sides, leaves the gap for flow of flue gas between little floor and the fork-shaped bend pipe flue inwall.The outer wall of fork-shaped bend pipe flue is application of slip enamel coating all, guarantees hot water cleaning and anticorrosion.Two collection flues that are positioned at the hot water tank upper portion side wall can be connected in two branch smoking pipe upper ends of fork-shaped bend pipe flue, and the outlet of two collection flues is connected two imports of a range hood and realized smoke evacuation.

The utility model has following conspicuous advantage compared with prior art: because the utility model adopts fork-shaped bend pipe flue, increase the heat exchange area of flue gas and water, can be comparatively fast to the water heat temperature raising, and the thermal efficiency is higher; By the smoke evacuation of two branch smoking pipes, can more even smooth and easy smoke evacuation, and still keep original less outer casing width and kitchen tools supporting.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is the cutaway view at A-0-0-A place among Fig. 1.

An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, these family expenses multi-functional water heater includes a water heater that is made of shell 6, the hot water tank 10 that water inlet 4 and delivery port 17 are arranged, burner hearth 7 and flue 11.Flue 11 is for passing the fork-shaped bend pipe flue of hot water tank 10 inner chambers, and top, burner hearth 7 center is connected in its lower end, and its middle part beginning is crooked and be branched into two branch smoking pipes, and two branch smoking pipe upper ends pick out from hot water tank 10 sidewalls.Be provided with damping baffle plate 12 in the fork-shaped bend pipe flue 11.Damping baffle plate 12 is along fork-shaped bend pipe flue 11 centers lath to be set, and the little floor that is staggered in these lath both sides, leaves the gap for flow of flue gas between little floor and fork-shaped bend pipe flue 11 inwalls.The equal application of slip enamel coating of fork-shaped bend pipe flue 11 outer walls.Two imports that a range hood 15 is connected in the outlet that 13, two the collection flues 13 of two collection flues that are positioned at hot water tank 10 upper portion side wall are connected in two branch smoking pipe upper ends of fork-shaped bend pipe flue 11.Hot water tank 10 is by carbon steel sheet punching press and welding fabrication, the equal application of slip enamel coating of its inwall.Shell 6 is a console mode bin shape structure, and gas-cooker 14 is arranged at its top.Hot water tank 10 outer walls have heat-insulation layer 3, reduce external heat transfer loss.Hot water tank 10 belows are burner hearths 7, and a burner 5 is installed in the burner hearth 7.The gas kitchen pipe joint 16 of connecting fuel gas source is arranged on the shell 6, and gas kitchen pipe joint 16 is connected gas-cooker 14 and burner 5.On the Gas Pipe that is communicated with burner 5 temperature controller 4 is housed, its temperature-sensing probe stretches in the hot water tank 10.The temperature that temperature controller 4 automatic controls have been set.The model that temperature controller adopts Italian Citicorp to produce is 610AC ₃Temperature controller.A safety valve 2 is arranged at hot water tank 10 tops, is used for the over-temp and over-pressure protection, when the heat hydraulic pressure surpasses 1.05MPa, discharges hot water when the hot water temperature surpasses 99 ℃ automatically, and release pressure prevents to produce steam.The model that safety valve 2 adopts U.S. China to agree the production of adjuster company is the safety valve of TP1100-4C.A sewage draining exit 8 is arranged at the bottom of hot water tank 10, is used to connect blow-off pipe, regularly discharges the sediment in the hot water tank.Electrode bar 1 of hot water tank 10 top interpolations, electrifiable turns usefulness into, slows down the corrosion of hot water tank.
