Description

A kind of full-automatic drying machine

The utility model relates to a kind of full-automatic drying machine, is meant a kind of automatic fuel gas formula dryer especially.

At present, commercially available dryer basic structure is based on box-shaped, has side to open drum-type and back down drum-type or back down a upright bucket drying formula.Drying mode is to adopt the heating of electric energy heater element as the dryer thermal source, adopt fixed routine, timing controlled mode drying time, therefore can't regulate heating load by the temperature and the degree of drying of clothing, can not judge automatically whether clothing dries, the drying process is general consuming time longer.After treating that dryer is shut down, often there is clothing phenomenon also not dried or that dry already, causes the waste of the time and the energy, and need the user often to look after.

The purpose of this utility model provides a kind ofly can control and judge the cloth drying degree automatically, regulates heating load automatically, controls the automatic fuel gas formula dryer of working procedure automatically by clothing temperature and its degree of drying.

A kind of automatic fuel gas formula dryer according to the above-mentioned purpose design, comprise engine housing, there is gate in the housing front, and the drying bucket is arranged in the housing, housing bottom below the drying bucket has thermal source and drives the motor that the drying bucket rotates, and thermal source wherein is gas burner and assembly thereof.The said burner assembly comprises gas inlet pipe, burnt gas switch valve and the combustion chamber of being docile and obedient the preface assembling, burner is arranged in the combustion chamber, the igniting pin is arranged on the burner, and the combustion chamber is connected with the air inlet passage, and the other end of air inlet passage is connected with air inlet on the drying bucket; Burner assembly also comprises respectively the proportional control valve that is connected with the combustion chamber with the burnt gas switch valve, and the thermistor in main thermocouple on the burner and the air inlet passage is positioned at the secondary thermocouple that top, combustion chamber is used to detect abnormal combustion.

Drying bucket in the housing is made up of ladle body and the front end panel that is fixed on the casing, and ladle body and front end panel are for movingly, and front end panel is provided with clothing temperature thermistor and clothing humidity sensor.Have the gas outlet on the rear wall of drying bucket, the gas outlet is positioned at the exhaust passage, and the rotating shaft of drying bucket, exhaust fan and exhaust outlet thermistor are arranged in the exhaust passage; Also be provided with the temperature controller of exhaust passage parts superheat protecting function in the outside, exhaust passage.In addition, described burner is the horizontal positioned state, or is upright laying state; Be positioned on the Motor Drive belt of burner side and be equipped with tension pulley and the belt tension microswitch is housed below belt.

The utility model compared with prior art, thermal efficiency height can utilize and energy savings better; Automatically the cloth drying degree can be controlled and judge to control and automaticity height automatically, regulate heating load automatically, control working procedure automatically by clothing temperature and its degree of drying, realized that the drying process is full-automatic.

Accompanying drawing 1 is that the master of the utility model broken section looks schematic diagram; Accompanying drawing 2 is broken section enlarged diagrams of accompanying drawing 1; Accompanying drawing 3 is that the C-C of accompanying drawing 1 is to cross-sectional schematic.

With reference to accompanying drawing 1 and 3.There is gate 10 in front at the utility model fuel gas dryer engine housing 29, on the door stroke feeler lever 11 is arranged, and has in the door with stroke feeler lever coupling, in order to control the microswitch 12 of drying program; Drying bucket 16 is arranged in the housing, the motor 25 that housing bottom combuster 27 below the drying bucket and driving drying bucket rotate, and is furnished with tension pulley 23 and as the fracture belt tension microswitch 24 of alarm switch of belt, the burner 6 that is horizontal positioned state 26 or is upright laying state 30 is arranged in the combustion chamber, and motor drives belt transmission fan 20 by belt pulley 22.

With reference to accompanying drawing 2.Burner assembly comprises gas inlet pipe 1, burnt gas switch valve 2, the proportional control valve 3 of being docile and obedient the preface assembling, igniting pin 4 is arranged on the burner fire hungry ghosts who spit fire and be used to detect the main thermocouple 5 of combustion position, also be provided with the secondary thermocouple 28 that is used to detect abnormal combustion on top, combustion chamber, the combustion chamber is connected with air inlet passage 7, thermistor 8 as the intake air temperature sensor is arranged in the passage, and the other end of air inlet passage is connected with air inlet 9 on the drying bucket.The drying bucket is made up of ladle body and the front end panel 13 that is fixed on the casing, front end panel be provided with as the clothing temperature thermistor 14 of clothing temperature sensor with contact on-off type clothing humidity sensor 15.On the rear wall of drying bucket, have and be convenient to the gas outlet 19 that moisture is discharged, connect the rotating shaft of drying bucket is arranged in the exhaust passage 17 of gas outlet, exhaust fan 20 and as the exhaust outlet thermistor 18 and the parts overtemperature protection temperature controller 21 of exhaust outlet temperature sensor.

Operation sequence of the present utility model is:

Connect power switch and promptly enter the standard operational mode, also can select operational mode as required voluntarily, at this moment motor start-up also detects the interior clothing temperature of exhaust outlet temperature and drying bucket simultaneously if gate is closed then.When exhaust outlet temperature and clothing temperature are lower than temperature is set, then continues heating; If exhaust outlet temperature and clothing temperature are higher than a certain temperature that is provided with, then close proportional control valve gradually or until closing burnt gas switch valve and proportional control valve.Circulate with this, after the drying standard that reaches the setting of clothing humidity sensor, automatic self-closing gas.In the work, main thermocouple flame detection temperature is less than when setting value, thinks loss of ignition, and alarm rings, and gas valve is closed; The flame detection temperature is then lighted a fire successfully greater than setting value, enters fault detection program, if occur abnormal conditions then gas valve close, normally then enter selected operational mode and finish, alarm prompting up to drying.When belt fractures or overheat protective relay when action, then power supply is directly cut off, and shuts down.
