Abstract
The present invention relates to a kind of temperature acquisition of air heating system and heating system guard methods; the air heating system heating element and temperature sensor; temperature sensor is arranged in the heated perimeter of heating element; the air-out direction in fan is arranged in heating element; air heating system first passes through the temperature sensor acquisition current environmental temperature before starting, and is recorded as environment temperature Ta.The first step of the present invention is acquisition environment temperature, and second step controls for normal heating, can prevent air heating system and the machine equipped with the system（Such as dish-washing machine）It is operated under limiting ambient temperature, in fact it could happen that the case where heater works normally but reports failure by mistake.
Description
Technical field
The present invention relates to a kind of air heating system, the temperature acquisition and heating system of especially a kind of air heating system
Guard method.
Background technology
Shown in Figure 1, air heating system includes mainly for sucking and the fan of blow out air, restriction air flowing
The air duct in direction, the heating element for heating air and the temperature sensor for detecting air heating temperature.Air heats
System, which is widely used in dish-washing machine, dryer etc., has the field of household appliances of drying function.
All it is usually the direct collecting temperature of temperature sensor in current air heating technique, and expected temperature is not achieved
Degree then thinks that heating element damages.Consider when being possible to design period temperature decision threshold due to existing technology condition it is insufficient or
Test it is insufficient, when machine operation is under limiting ambient temperature, in fact it could happen that heater work normally but wrong report failure the case where.
Invention content
It is an object of the invention to overcome above-mentioned the shortcomings of the prior art, and providing one kind prevents machine operation in pole
Limit environment temperature under, in fact it could happen that heater work normally but report by mistake failure the case where air heating system temperature acquisition and
Heating system guard method so that the machine of air heating system and the application system adapts to different environment temperature work.
The object of the present invention is achieved like this：
A kind of temperature acquisition method of air heating system, the air heating system heating element and temperature sensor, temperature
Sensor is arranged in the heated perimeter of heating element, and the air-out direction in fan is arranged in heating element, and feature is being air
Heating system first passes through the temperature sensor acquisition current environmental temperature before starting, and is recorded as environment temperature Ta.
The purpose of the present invention can also use following technical measures to solve：
As a more specific scheme, environment temperature Ta is recorded after collecting temperature stabilization.When due to just starting to measure, temperature
Degrees of data will repeatedly change moment, and general this variation stops quickly（General one or two second）, temperature data will settle out,
There is no external influence, change will not be easy to happen；And after temperature data is stablized, which is more accurately.
As further embodiment, the air heating system further includes the fan dried to heating element, temperature sensing
Device is arranged in direction windward, starts fan when acquiring current environmental temperature, without starting heating element.Fan is activated individually
Afterwards, the cold wind of current environment will pass through heating element and blow to temperature sensor, and therefore, temperature sensor can be more acurrate
Ground obtains current environmental temperature.Environment temperature determines that the initial temperature of heating element equally also contributes to Wen Sheng when its work
Speed, so, judge that the initial temperature of heating element is quite must equipped with temperature sensor windward at heating element rear
It wants.
As further embodiment, after recording environment temperature Ta, start heating element, temperature sensor continues acquisition temperature
Degree, desired value Tb is not achieved in temperature after a period of time, reports malfunctioning heating elements.Desired value Tb is according to default heating element Wen Sheng
Speed is related with temperature when combining heating element original state.The program is solved in the case where not increasing system hardware cost
Heating system is under different environment temperature working conditions, the problem of being easy to report heater failure by mistake.
A kind of heating system guard method of air heating system, feature are being, when air heating system starts one section
Between after temperature be not achieved desired value Tb, report malfunctioning heating elements；Desired value Tb is the environment before being started according to air heating system
Depending on temperature Ta is plus the normal temperature rise value A of setting.So when practical temperature rise value is less than normal setting temperature rise value range, it will
Desired value Tb is not achieved, illustrating greatly may heating element failure.
As further embodiment, the temperature acquisition after environment temperature and air heating system startup derives from same temperature
Sensor can reduce production cost.
As further another program, the temperature acquisition of environment temperature derives from a temperature sensor, air heating system
Temperature acquisition after system starts derives from another temperature sensor.
Beneficial effects of the present invention are as follows：
（1）The first step of the present invention is acquisition environment temperature, and second step controls for normal heating, can prevent air heating system and set
There is the machine of the system（Such as dish-washing machine）It is operated under limiting ambient temperature, in fact it could happen that heater works normally but wrong report failure
The case where.
Description of the drawings
Fig. 1 is one example structure schematic diagram of air heating system.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and embodiments：
It is shown in Figure 1, it is the structural schematic diagram of existing air heating system, includes mainly for sucking and blow out air
Fan 1 limits the air duct 3 of air-flow direction, the heating element 2 for heating air and for detecting air heating temperature
Temperature sensor 4.Air heating system, which is widely used in dish-washing machine, dryer etc., has the field of household appliances of drying function.Air duct 3
One end is input terminal, and input terminal is connect with the air outlet of fan 1, and 3 other end of air duct is output end, and heating element 2 and temperature pass
Sensor 4 is successively set in the air duct 3 between input terminal and output end.
A kind of temperature acquisition method of air heating system, air heating system first pass through the temperature sensor before starting
Current environmental temperature is acquired, and environment temperature Ta is recorded as after collecting temperature stabilization.
Start fan 1 when acquiring current environmental temperature Ta, without starting heating element 2, extraneous cold wind is blown into wind through fan
Road 3, and cold wind is guided to pass through heating element 2 and temperature sensor 4 successively.
After recording environment temperature Ta, start heating element 2（Due to only starting fan 1 before without starting heating unit
Part 2 cannot generate hot wind, it is therefore desirable to start heating element 2）, temperature sensor 4 continues collecting temperature, after a period of time
Desired value Tb is not achieved in temperature, reports malfunctioning heating elements.Such as：When 2 minutes collecting temperatures of heating are less than 40 °C, report heater event
Barrier.
A kind of heating system guard method of air heating system, air heating system start（It refers to beginning to warm up）One
Desired value Tb is not achieved in temperature after the section time, reports malfunctioning heating elements；Desired value Tb is before being started according to air heating system
Depending on environment temperature Ta is plus the normal temperature rise value A of setting.
Temperature acquisition after environment temperature and air heating system start derives from same temperature sensor.
