Abstract
The utility model provides a water heater with an incomplete combustion preventing device. The water heater comprises an outer case, a heat exchanger, a burner, a water control valve, a pulse ignitor and a water drive safety valve. The utility model is characterized in that the utility model is also provided with an ion probe and a temperature controller. The sense needle of the ion probe is arranged in the place between the burner and the heat exchanger, a through hole is arranged on a case body in the middle of the heat exchanger, the temperature controller is arranged at the exit end of the through hole, and the ion probe and the temperature controller are connected with the pulse ignitor through conducting wires. The utility model has the advantages of convenient assembly, easy controllability, safe utilization, low cost, etc., and is suitable for being used for different kinds of gas water heaters.
Description
The utility model relates to gas heater, and particularly a kind of have a water heater that prevents imperfect combustion device.
For prevent gas heater because of imperfect combustion produces excessive carbon monoxide, cause the generation of human life accident, enclose family regulation straight-line water heater must install and prevent imperfect combustion device.And to meet in the national standard requirement of bad test index of ventilation and heat exchanger part blocking test index.At present, prevent that imperfect combustion device from having two kinds; First double-thermocouple device is arranged at the upper and lower side of heat exchanger with two thermocouples, prevents imperfect combustion by controlling its temperature difference.This device weak point is the cost height, and installs inconvenient.It two is air-sensitive formula devices, prevents imperfect combustion by the carbon monoxide content in the control heat exchanger.The weak point probe of this device is the knot charcoal easily, and a long sensitiveness is poor when long, and cost is higher.In addition, the sensitivity of above-mentioned two kinds of devices is also poor.
It is a kind of simple in structure, easy to assembly that the purpose of this utility model is to provide, easily control and lower-costly have a water heater that prevents imperfect combustion device.
Task of the present utility model realizes by this way; This water heater includes shell, heat exchanger, burner, water control valve, pulse igniter and water drive safety valve, it is characterized in that also having ion probe and temperature controller, the inductive needle of ion probe is arranged in the space between burner and the heat exchanger, on the housing at heat exchanger middle part, have a through hole, temperature controller is contained in the port of export of through hole, and ion probe is connected with pulse igniter by lead with temperature controller.
Operation principle of the present utility model is such: when indoor anoxic, water heater produces imperfect combustion, flame is consolidated anoxic and is taken off fire, gas current also because of take off fire, equivalent resistance increases and descends, ion probe is passed to pulse igniter with signal, and the substitution ratio by impulse circuit IC closes water drive safety valve (magnetic valve) immediately, burner is flame-out, thereby realizes preventing unburnt requirement.When heat exchanger took place partly to stop up, the circulation of burning indoor temperature rising flame was not smooth, also produces excessive carbon monoxide.At this moment, the flue gas of high temperature overflows outward from housing through-hole, and the temperature at temperature controller place is raise rapidly, and temperature controller moves at once, closes magnetic valve, and the burning of burn-out device reaches the safeguard protection effect.This shows that the utility model makes water heater can meet two index requests of national standard fully by duplicate protection, the assurance user's is safe in utilization.Advantages such as in addition, the utility model also has simple in structure, and cost is low and easy for installation.
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Fig. 1 opens the front view of panel for the utility model.
As shown in Figure 1, the utility model is identical with existing water heater, mainly by shell 1, and heat exchanger 2, burner 3, water control valve 4, pulse igniter 5 and water drive safety valve 6 are formed.Different is also to be provided with ion control pin 7 and temperature controller 8.The inductive needle of ion probe 7 is arranged in the space between burner 3 and the heat exchanger 2, makes ion control pin 7 can sense the variation of flame at any time.By test, it is comparatively suitable that the inductive needle of ion probe 7 is arranged in the burner 3 2-3 millimeter place, first row's burner top.Install easily at this place, and susceptibility is than higher.Temperature controller 8 is arranged on the port of export place of heat exchange along the through hole in 2 housings middle part.This through hole is suitable from heat exchanger 2 bottom surface 60-80 millimeter places, and this place experiences the variations in temperature in the heat exchanger 2 easily.For well, present embodiment is selected 12 millimeters for use to this through-hole diameter with the 10-14 millimeter.About 2 millimeters away from through hole be of temperature controllers 8 are so that gas overflows.Heat exchanger 2 produces when stopping up, and this place's temperature can reach 230 ℃, so the selection of the control temperature of temperature controller 8 is suitable for 180-190 ℃.
The utility model is suitable for various gas heaters to be used.
