Description

Domestic stove exhauste heat water heater

The utility model relates to a kind of stove afterheat energy-saving water heater of family or similar applications, and this water heater especially suitable coals steam stove, oil gasifier is family's use of thermal source.

The present residue heat water heater that uses of kitchen range has and sees the city, and shape is a circular shell, its water is injected be positioned over the burner periphery; Chinese patent " a kind of water heater " CN2058733V and for example; Chinese patent " energy-saving water heater " CN2037449V, its shortcoming has surplus heat, and to imitate profit not high, and water receptacle is insulation not, and water is easily cold, uses also inconvenient.

It is high that the purpose of this utility model is to provide a kind of heat to imitate, and the hot water thermal insulating time is long, and is easy to use, stove residue heat water heater rational in infrastructure.

The metallic coil that the utility model is achieved in that the heater that flames do is other is two ends up and down, and the container of filling water that is greater than or equal to heater with a horizontal level is connected.Water proportion after helix tube is heated in the pipeline reduces upwards to flow, flow to water receptacle from the upper water-out mouth through pipeline, flow to water receptacle top again, the following water inlet of helix tube, connect the bottom of container or the delivery port of bottom, side, the total container of the water of water receptacle bottom top cold, than great, water just flows in the helix tube; Water is subjected to thermal cycle, water heating in the container, and after helix tube is not heated, the water loop termination.Because water receptacle has good insulation, the interior water of container is difficult for cold, and container is provided with dipperstick, thermometer, super water yield delivery port so that easy to use.Water inlet (17) in the container, when being contained in container bottom, need connect a short tube, short tube is flowing of favourable hot water on the one hand, improve water inlet (17) water level in the container on the other hand, make the container water inlet be higher than delivery port (16), like this at container when top adds water, water is earlier from delivery port (16) flow ipe, air in the pipeline is discharged from water inlet (17), in case too much air is arranged in the pipeline, water is mobile when being unfavorable for heating, when water inlet pipe is contained in the container next door, when container water inlet (17) is higher than delivery port (16), just need not consider above situation.Besides the other heater of flame, when using the hemispherical pot, pot is placed on the stay-warm case upper inner edge, and to the diffusion of pot edge, thermal current flows out from cover top passage through stay-warm case after the exchange heat by the helix tube intermediate space flame again in the bottom of a pan; When using the cylindricality pannikin, on the cooking device support of Ying Zailu, put lastblock garden annular metal sheet, the outer garden of this plate is close with the helix tube inward flange, the garden is with by being good than big flame in this plate, the cylindricality pannikin is placed in the middle of the endless metal of garden, and flame spreads along the edge in the bottom of a pan, and thermal current is through annulus metallic plate bottom.By the helix tube gap, cold and hot exchange is flowed out outside the cover after stay-warm case again.Helix tube is one or more pipeline parallel connection, and the interior water resistance of long tube is big more more for water pipe, and water flow velocity is slow, and the parallel connection of multichannel helix tube has increased flow area, has reduced water resistance in the pipe, the favourable raising thermal efficiency; Wear the metal heat absorbing sheet on the metallic coil, increased endotherm area.Stay-warm case insulation in addition, be provided with the flame observation window above, have windproof and decorative effect, do not influence stove again and normally use, also can further improve stove waste heat efficient, only need during use container is filled water, when your food is cooked when ripe, the penstock under the container is opened in water nature heating in the cool-bag, and hot water will flow out.

Accompanying drawing 1 is a structural perspective of the present utility model, and wherein container (2) is that the stereogram of dissecting the angle is arranged, and (1) is the stereogram that the other heater of stove is dissected the angle.

Accompanying drawing 2 is the utility model principle schematic.

Below the utility model is described in further detail:

With reference to accompanying drawing

The utility model comprises the other heater of (1) flames do.(2) the insulation water receptacle is used to adorn water.(3) single channel metallic coil or two tunnel and two road above helix tubes in parallel are used for exchange heat.(4) helix tube upper water-out mouth.(5) water inlet under the helix tube.(6) be used for fixing the support of helix tube.(7) insulation metal cap, there are heat-insulation layer and decorative layer in the surface, mainly is insulation, and is windproof, and certain decoration function is arranged.(8) passage of stay-warm case.(9) the flame observation window on the insulating cover is used to observe flame.(10) cooking device support.(11) movable garden annular metal sheet.(12) the interior garden of garden annular metal sheet is being that good, more a little bit smaller garden cylindrical pot is placed in the annular metal sheet by enough flame, flame burns at pot bottom, along the bottom of a pan diffusion, thermal current leads to spiral metal tube from the annular slab bottom, and the garden annular metal sheet is placed on (10) cooking device support.(13) be through metal heat absorbing sheet on the metallic coil, be used to improve heat absorption efficiency.(14) tube connector of helix tube delivery port and water receptacle.(15) tube connector of helix tube water inlet and water receptacle is good with the heatproof flexible pipe; Available heatproof plastics, rubber, nylon tube be the available metal pipe also.(16) water receptacle delivery port.(17) water receptacle water inlet, it is communicated with through pipeline and helix tube (4) delivery port, when delivery port is contained in the water receptacle bottom, need connect a short tube, so that the high water exit container water inlet of delivery port (16).(18) insulation water receptacle outer wall, the available metal plate is made, and also available plastics or fiberglass are made, and various decorative layers are applied on the surface.(19) heat-insulation layer, available insulation material also can adopt vacuum heat-preserving.(20) insulation water receptacle inwall, available metal aluminium, copper, stainless steel, galvanized iron sheet or plating enamel, also useable glass steel, pottery, glass are made.(21) water level viewer is to observe the water yield in the water receptacle.(22) thermometer.(23) super water yield delivery port and outlet pipe (24) on the water receptacle, its effect is to flow out water during the water overfill in the Bedpan.(25) water receptacle bottom penstock.(26) insulation cover on the water receptacle.(27) hinge of insulation cover.(28) handle that covers.(29) the water receptacle hook is used for fixing container.(30) the fixing holder of water receptacle bar is used for fixing container.(31) branch pipe tee connection.(32) pipeline.(33) valve mainly is to be used for water receptacle is added water.

Can earlier water receptacle be filled water during use, but the threeway of dress water method heat water valve gate open piping adds water, and the container upper cover of also can fetching boiling water directly adds water to water receptacle, adds behind the water igniting and does food and get final product, water heating in a period of time rear water box, the valve of opening on the container can be emitted hot water.

Because the utility model has adopted above-mentioned design, makes it to contrast prior art and has the following advantages:

(1) the utility model is rational in infrastructure, stove waste heat hot water efficient height;

(2) stove is easy to use with residue heat water heater.

(3) water receptacle has good heat insulating ability, and the hot water thermal insulating time is long.
