Abstract

The utility model relates to a heater which is composed of a preheating part, a heating part and a shell body, wherein, a preheating water jacket is arranged in the heater; the flow direction of water and fire is countercurrent flow, so that heat exchange is promoted, and thermal efficiency is high. The utility model has a softened water function, and scale deposit basically can not be deposited. The utility model has a jetting dynamic effect, so that the cycle flow of cold and hot water can be accelerated. The heating part of the heater and the combustion part of a furnace body are separated, and in case a furnace uses a coal ball furnace and a honeycomb briquette furnace, fired coal can be completely combusted, and furnace seal is easy. The utility model has the advantages of compact heater structure, high thermal efficiency, easy fabrication and low cost. The utility model is suitable for the shower and the heating of peasant households and parts of households of a city and supplying the hot water for wash. The utility model has the advantages of convenient use and low use cost.

Description

Domestic water heater

The utility model relates to a kind of hot-water heater, the hot-water heater of especially family's shower, heating usefulness.

Existing application number is 88202027.7 " domestic hot water heater ", for peasant household and the shower of city part resident family, heating provide the hot water firing equipment.But from the processing and manufacturing aspect, technology is relatively more assorted multiple, and manufacturing cost is increased.In order to warm oneself, heater is connected with radiator when using, and directly makes the poor-performing of cold and hot water circulation, needs water pump to impel water circulation, owing to need water pump that the cost of firing equipment is increased, also increases the complexity of using.

The purpose of this utility model provides and a kind ofly is applicable to running water or does not have the peasant household of running water and the domestic hot water heater of the shower of city part resident family, heating.Used thermal source is liquefied gas, coal gas, coal, especially can use honeycomb briquette, and this brings great convenience to the user.The utility model is thermal efficiency height not only, and is easy to manufacture, and volume is little, and hot water has jet-action, and directly the performance of circulation is good to make hot and cold water, and anticorrosion is arranged, and the function of scaliness not substantially, but and continuous water supply, use reliably, convenient, cost of use is low.

The utility model is by heating part (10), and regenerator section (4) is formed with housing parts (2).Heating part is by delivery port (18), playpipe (16), and heating water jacket (11), heating clamber (13), aqueduct (15) and connecting screw (14) are formed.Regenerator section is by heat flow-conductive board (8), (19), and hot water jacket (5), (9) and water inlet pipe (23) are formed.Housing parts is by heating water jacket's shell (12), hot water jacket shell (3), (20), carrying handle (24) and throat (1) are formed, after cold water enters first hot water jacket (5) from water inlet pipe (23), enter second hot water jacket (9), flow into heating water jacket (11) through aqueduct (15) then, current in the water jacket flow into heating clamber (13), behind ebuillition of heated, spray to delivery port (18) by playpipe (16), because the speed of injection water is higher, jet place pressure is descended, by slit (17) amount of makeup water from heating water jacket (11), keep certain pressure,, can make the fine circulation of hot and cold water as be connected use with radiator.According to operating position flow size and required hot water temperature, water differs to establish a capital and is heated to boiling.The bottom cover of housing (2) is on stove, keep sealing, reduce thermal loss, and make the bottom (26) of flame heat heating water jacket (11), fire, cigarette is along the centre bore of heating water jacket through second heat flow-conductive board (19), with fire, cigarette preheating second hot water jacket (9), and through the centre bore of first heat flow-conductive board (8), preheating first hot water jacket (5), flue gas goes out throat (1) then.According to different thermals source, middle hot water jacket (9) can increase, and also can deduct, and the temperature that main foundation is a throat is advisable near room temperature, reduces and takes away heat from chimney, improves the thermal efficiency.Hot water jacket divides two-tiered water jacket up and down, and water inlet in the middle of the upper strata water jacket (6) enters lower layer of water cover (7) after around flowing to, again from around flow into central exit.Housing (2) is made up of the shell (20,22) of hot water jacket (5), (9) and heating water jacket's (11) shell (12), and each links each shell with bolt (21), and mobilizable carrying handle (24) is housed between hot water jacket.The outside of shell can be surrounded by insulation material, perhaps only wraps the outside of heating water jacket's shell (12).The spirality corrosion protection utmost point (25) is housed in the heating water jacket (11).

Advantage of the present utility model and good effect are owing to seal between stove and the heater, heater inside has hot water jacket again, and the flow direction of water inlet is an adverse current with the flow direction of fire, cigarette, promotes that heat exchange is perfect, reach temperature that throat (1) locates near room temperature, thereby thermal efficiency height; Effect with heating power demineralized water, not scaliness or few scaliness substantially; Dynamic action with injection quickens circulating of hot and cold water, for shower, heating provide very advantageous conditions; The heating part of heater separates with the body of heater combustion parts, as making fired coal combustion perfect with coal dust ball stove, honeycomb briquette stove, and also easy banking.

The explanation of accompanying drawing drawing:

The utility model is described in further detail below in conjunction with embodiment:

Embodiment 1, when the bathroom has when using under the running water condition, running water pipe is received tube, heater inlet (23), the flexible pipe of belt switch shower nozzle is received outlet (18), after cold water enters heater, heater is placed on the stove, flame is aimed at heating water jacket (11), especially it is more obvious that gas burner, honeycomb briquette stove, flame are aimed at heating water jacket's effect.When the temperature in the device to be heated arrived the required temperature of shower, the switch of opening on the shower nozzle can carry out shower by hot water without interruption, and hot water flow is controlled by water tap.If there is not the condition of running water, heater can heat the high water tank of hanging, and treats that temperature is raised to when temperature required, can use shower.

Embodiment 2, for the purpose of warming oneself, improve room temperature.Heater delivery port (18) can link to each other with water inlet of radiator, and the return pipe of radiator is connected with the water inlet pipe of heater (23), and the additional mouth of a river and emptying gas port are arranged in the pipeline.When the heater heating, hot and cold current circulate, and improve indoor temperature by radiator heat-dissipation.

Heater also can be bathtub, washing etc. hot water is provided, and also can provide drinking water.

Embodiment 3, running water pipe, and heater, radiator, shower bath head (or bathtub) is linked to be a pipeline, by valve control water route and flow.Because the water that comes out of heater is softening through heating power, in the pipeline and water be cleaner, can supply shower.When wanting shower, close the path of radiator, the temperature and the flow of running water switch control bathing water.When needs are warmed oneself, close running water and shower bath head, open radiator, improve room temperature, if area of heat-supply service is excessive, can in pipeline, reach required indoor temperature by one or several heater in parallel.
