Description
Technical field
The present invention relates to a kind of zero cold water gas heaters.
Background technique
After a shutdown, forced-ventilated mechanism can continue working a period of time to water heater, the then (burning of the burner inside water heater
Heat exchange module) it can cool down rapidly, the heat exchanger tube (heat exchange linkage section) coiled on it also follows cooling, water heater restarting
Afterwards, heat exchanger tube (heat exchange linkage section) cooled down, the cold water temperature that is directly inputted from water supply connector it is relatively low, burner (burning
Heat exchange module) restarting after, it is very short with the heat-exchange time of heat exchanger tube, when water heater being caused to restart, be easy to appear hot water
The hot water quenching phenomenon of device just section output, midway downtime is longer, and hot water quenching phenomenon becomes apparent from, it is difficult in zero cold water combustion gas
It is applied on water heater.
Chinese patent literature CN106440330A discloses a kind of gas heater, fuel gas water heating system and combustion gas heat
The pre-heating mean of hydrophone, the gas heater include shell and the water inlet that the housing bottom is arranged in, water return outlet and go out
The mouth of a river is provided with the controller for controlling gas heater in shell, on the pipeline by water inlet to water outlet successively
Inflow temperature sensor, burner, water pot and leaving water temperature sensors are arranged in series, in water return outlet to inflow temperature sensor
It is additionally provided with water return pipeline, water pump and return water check valve are provided on water return pipeline, going out for water pump is arranged in return water check valve
The mouth of a river is between inflow temperature sensor, and return water check valve flows to inflow temperature sensor by water pump.
, by the way that water pot (i.e. water tank) is arranged on water heater internal duct (heat exchanger tube), water pot can store a certain amount of for it
Hot water (usually at 100-500 milliliters) and be located at close to water outlet pipeline on, when water heater is restarted, water heater just section
The hot water of output first flows into water pot, since the hot water stored in advance in water pot is more, and the heat of water heater just section output quenching
Water is less, is just exported by water outlet after the two mixing, therefore, after water heater restarts, heat that water outlet substantially exports
Water does not have apparent quenching phenomenon, is particularly suitable for applying on zero cold water gas heater.
But water pot is in can-like, can additionally occupy water heater inner space, the volume of water heater is enabled to significantly increase, and
The manufacturing cost of water pot is very high, and therefore, it is necessary to be further improved.
Summary of the invention

The check valve connection of water end (W.E.) flow direction, the first water inlet end are connected by the tail end of pipeline and water outlet connector, and the second water inlet end passes through pipe
The connection of the tail end of road and water supply connector.
The beneficial effects of the present invention are:
The coil pipe of continuous detour is set by the water outlet linkage section in heat exchanger tube, and coil lengths long enough makes to form energy in coil pipe
Enough store the hot water water storage cavity of more hot water, water heater is after of short duration shutdown restarting, hot water that water outlet connector substantially exports
There is no apparent quenching phenomenon, there is no water tank inside water heater, production cost is greatly lowered, and be not take up in water heater
Portion space, water heater volume is smaller, is particularly suitable for applying on zero cold water gas heater.
Additional aspect and advantage of the invention will become obviously in following description section, and reality through the invention
It tramples and recognizes.
Detailed description of the invention
Fig. 1 is the structure principle chart of one embodiment of the invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1, this zero cold water gas heater, including host 1 which is provided with water supply connector 11, combustion heat-exchange module
12, water outlet connector 13 and heat exchanger tube, the heat exchanger tube include the water inlet linkage section 21 being sequentially communicated, heat exchange linkage section 22 and
It is discharged linkage section 23, the water inlet linkage section 21 is connect with the head end of water supply connector 11, and heat exchange linkage section 22 is coiled in burning and changes
In thermal modules 12, water outlet linkage section 23 is connect with the head end of water outlet connector 13, and the water outlet linkage section 23 is the disk of continuous detour
It manages (such as continuous helical shape pipe, continuous S-shaped pipe), forms hot water water storage cavity in coil pipe, the volume of hot water water storage cavity is greater than heat exchange
The coil pipe of continuous detour is arranged in the water outlet linkage section 23 of heat exchanger tube for the one third of the volume of linkage section 22, the technical solution,
Coil pipe can be made up of oxygen-free copper round tube, coil lengths long enough, make to form the hot water storage that can store more hot water in coil pipe
Water cavity (capacity reaches 100-500ml), water heater is after of short duration shutdown restarting, heat that water outlet connector 13 substantially exports
Water does not have an apparent quenching phenomenon, and not no conventional water tank inside water heater can be greatly lowered production cost, improve and produce
Product competitiveness, and coil pipe is not take up water heater inner space, it is only necessary to original clearance position coiling in water heater,
Water heater volume is smaller, is particularly suitable for applying on zero cold water gas heater.
