Abstract
The utility model discloses a gas water heater burner temperature induction oxygen lack safety protector, comprising a controller and a gas control electromagnetic valve electrically connected with the controller. The gas water heater burner temperature induction oxygen lack safety protector is characterized in that a temperature sensor is provided above the burner component for checking the flame temperature of the burner, and the temperature sensor is connected with the controller. The gas water heater burner temperature induction oxygen lack safety protector can be applied on a gas heater, having simple structure, low cost and table working performance. The gas water heater burner temperature induction oxygen lack safety protector can effectively protect users and finance, with wide application.
Description
Technical field
It is the firing equipment technical field of fuel that the utility model relates to natural gas, liquefied petroleum gas, more particularly relates to a kind of anoxia protection arrangement that is used on the gas heater.
Background technology
At present; combustion gas is as the important energy source of people's life; be widely used in people's the family life; healthy and personal safety for protection people in the use of Gas appliance; the extensive use on the Gas appliance of countries in the world of a kind of anoxia protection arrangement; it controls that air enters by bimetal leaf what; complex structure; cost is higher; bimetal leaf is acted upon by temperature changes bigger in the use; cause bi-metal plate deformed, directly influence the accuracy of anoxia protection arrangement action, poor reliability.For this reason; people propose a kind of new structure at its shortcoming; as Chinese patent application number is 00219258; the applying date is on January 28th, 2000; denomination of invention is a kind of anoxia protection arrangement; it is by base plate; thermocouple; igniter head; induction tunnel; connecing gas head and nozzle forms; thermocouple and igniter head are fixed on the base plate side by side; the control end of thermocouple is connected to electromagnetic control coil; induction tunnel is fixed on the base plate; be connected with combustion head in its head end; the temperature-sensitive end of thermocouple and the discharge end of igniter head are positioned at the flame interaction scope of induction tunnel combustion head; the tail end of induction tunnel is connected with and connects the gas head, and the outer wall that connects the gas head is provided with air admission hole, and the tail end that connects the gas head is connected with inside and is provided with filter screen and ruby nozzle.This patent utilization connects the inlet of gas head control air, can save the bimetal leaf parts, improves stability.This structure of its shortcoming is wanted to judge by thermocouple whether the flame of combustion head exists earlier, just electromagnetic control coil is moved, promptly as long as flame exists and acts under the state of temperature-sensitive end of thermocouple, no matter flame temperature height can valve-off, be difficult to realize that combustion gas still keeps its security under the state of burn incompletely, but also can cause the waste of resource, the raising of cost.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, cost is low, and gas heater burner's temp sensing type anoxic safety guard of stable work in work.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of gas heater burner's temp sensing type anoxic safety guard; the combustion gas control magnetic valve that comprise controller, is electrically connected with controller; it is characterized in that: it is that the temperature sensor that detects combustor flame temperature is set above burner assembly, and this temperature sensor and controller link together.
As further specifying of such scheme, described temperature sensor is arranged on the burner outer wall by base.
Described temperature sensor is arranged on the housing inboard of gas heater over against the burner flame position.
Described temperature sensor is a thermocouple.
The termination of described thermocouple is tapered.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the utility model is on the basis of existing anoxia protection arrangement; flame periphery in burner is provided with a temperature sensor; the temperature that is used for the test flame internal flame; can be by setting in advance certain temperature range in the controller; when being lower than the temperature range that sets in advance, the detected temperature of temperature sensor closes magnetic valve at once; stop to the burner delivery of fuel gas; make the security and the stability of gas-fired equipment further improve, personal safety and the property safety that ensures the user had important effect.

Description of reference numerals: 1, burner 2, base 3, temperature sensor
The specific embodiment
As shown in Figure 1 and Figure 2; the utility model gas heater burner temp sensing type anoxic safety guard; the combustion gas control magnetic valve that comprise controller, is electrically connected with controller; it is that the temperature sensor 3 that detects combustor flame temperature is set above the assembly of burner 1; this temperature sensor 3 links together with controller; temperature sensor 3 is arranged on burner 1 outer wall by base 2; and the housing inboard that is arranged on gas heater is over against the burner flame position; in the present embodiment, temperature sensor 3 is a thermocouple.
In the use, when burner assembly is passed through in combustion gas, light combustion gas, the gas of being lighted is exporting out formation flame, under normal state, in atmosphere the composition of each gas and gas transportation facilities just often, flame burns away, temperature sensor is monitored flame temperature in real time to controller delivery temperature value; When the composition of each gas in the atmosphere or gas transportation facilities were undesired, when causing the internal flame temperature of flame to be lower than the temperature range that presets, controller sent pulse signal to combustion gas control magnetic valve, and it is closed, and stops to continue to the burner delivery of fuel gas.
The utility model is not limited to the foregoing description; described temperature sensor can also be arranged on Anywhere as requested; as long as temperature sensor can contact the flame internal flame; any those skilled in the art can do numerous modifications and variations; under the spirit that does not break away from utility model, all in the claimed scope of the utility model.
