Abstract
The invention discloses a heating protection device of a roller washing machine, which avoids the damage to the roller washing machine caused by the excessive addition of washing powder when the roller washing machine is used for washing and prolongs the service life of the roller washing machine and a heating pipe. A temperature sensor is connected with a microcomputer chip, and the microcomputer chip sends heating control signals to the heating pipe through a heating control device, is also connected with a water level sensor and is used for sending water inlet control signals to a water inlet valve through a water inlet control device, and the invention also provides a heating protection method of the roller washing machine.
Description
Technical field
The present invention relates to electronic technology field, the heating protection method of particularly a kind of heating protecting device of roller washing machine, and roller washing machine.
Background technology
Roller washing machine if heating tube damages, can can't normally use by guide roll tube washing machine in the heated scrub process; In order to protect heating tube, what roller washing machine adopted at present is temperature sensor slope resist technology, when heating; Judge the temperature rise of temperature sensor,, then be judged to heating and make mistakes if temperature rise is too fast or slow excessively; Close and add thermal output, protect heating tube; After adding washing powder in actual use, because friction can produce foam, if in the process of heated scrub; Because it is on the high side that washing powder adds, the foam of generation is on the high side, and the heating tube of roller washing machine is in the middle of the foam; Rather than place water, in this case, having the very big temperature sensor slope resist technology that possibly make can't work; This moment heat time heating time long words; Can cause the damage of heating tube, influence the use of roller washing machine, must keep in repair just and can deal with problems.
Summary of the invention
The technical problem that the present invention will solve provide a kind of avoid roller washing machine in when washing owing to add the heating protecting device of roller washing machine in the service life of the excessive damage that causes of washing powder, prolongation roller washing machine and heating tube.
The technical scheme that addresses the above problem is: the heating protecting device of this roller washing machine; Temperature sensor is connected with microcomputer chip; Microcomputer chip will heat control signal through heating control apparatus and send heating tube to; Microcomputer chip also is connected with level sensor, and microcomputer chip sends water intaking valve to through the inlet control device control signal of will intaking.
Through adopting the level sensor use that combines with temperature sensor; In the process of roller washing machine heated scrub; The signal of microcomputer chip while collecting temperature sensor and level sensor, the water level lift-off value of level sensor signal stop washing and heating after being higher than watermark threshold, after additional certain water yield; Again get into heated scrub; If the temperature rise slope of temperature sensor signal is too high or too low, then close and add thermal output, so just can avoid roller washing machine when washing owing to add the service life of the excessive damage that causes of washing powder, prolongation roller washing machine and heating tube.
A kind of heating protection method of roller washing machine also is provided, has may further comprise the steps:
(1) microcomputer chip gets into the heated scrub flow process, opens heating control apparatus;
(2) changeing-during the motor halted state of stopping washing, gather level sensor signal and temperature sensor signal;
(3), then close heating control apparatus and stop washing, execution in step (5) if the water level lift-off value of level sensor signal is higher than watermark threshold;
(4) if the temperature rise slope of temperature sensor signal is higher than the temperature maximum or is lower than the temperature minimum of a value, then stop heating, mark error signal, execution in step (10);
(5) microcomputer chip is opened inlet control device, opens water intaking valve, and the water level lift-off value of level sensor signal stops moisturizing after being higher than watermark threshold or flooding time overtime threshold value, execution in step (6);
(6) changeing-during the motor halted state of stopping washing, gather the level sensor signal and the temperature sensor signal of roller washing machine;
(7) water level signal of roller washing machine is judged,, then added and close heating control apparatus, execution in step (10) if the water level lift-off value of level sensor signal is higher than watermark threshold;
(8) if the temperature rise slope of temperature sensor signal is higher than the temperature maximum or is lower than the temperature minimum of a value, then stop heating, mark error signal, execution in step (10);
(9) after microcomputer chip judges that temperature reaches temperature threshold, close heating control apparatus;
(10) microcomputer chip continues washing flow, closes heating control apparatus this moment.
Description of drawings
Fig. 1 is circuit theory diagrams of the present invention.
The specific embodiment
As shown in Figure 1; The heating protecting device of this roller washing machine; Temperature sensor is connected with microcomputer chip; Microcomputer chip (heating protecting device) will heat control signal through heating control apparatus and send heating tube to, and microcomputer chip also is connected with level sensor, and microcomputer chip sends water intaking valve to through the inlet control device control signal of will intaking.
Through adopting the level sensor use that combines with temperature sensor; In the process of roller washing machine heated scrub; The signal of microcomputer chip while collecting temperature sensor and level sensor, the water level lift-off value of level sensor signal stop washing and heating after being higher than watermark threshold, after additional certain water yield; Again get into heated scrub; If the temperature rise slope of temperature sensor signal is too high or too low, then close and add thermal output, so just can avoid roller washing machine when washing owing to add the service life of the excessive damage that causes of washing powder, prolongation roller washing machine and heating tube.
A kind of heating protection method of roller washing machine also is provided, has may further comprise the steps:
(1) microcomputer chip gets into the heated scrub flow process, opens heating control apparatus;
(2) changeing-during the motor halted state of stopping washing, gather level sensor signal and temperature sensor signal;
(3), then close heating control apparatus and stop washing, execution in step (5) if the water level lift-off value of level sensor signal is higher than watermark threshold;
(4) if the temperature rise slope of temperature sensor signal is higher than the temperature maximum or is lower than the temperature minimum of a value, then stop heating, mark error signal, execution in step (10); Temperature value when the temperature value when wherein the temperature maximum is short circuit, temperature minimum of a value are open circuit;
(5) microcomputer chip is opened inlet control device, opens water intaking valve, and the water level lift-off value of level sensor signal stops moisturizing after being higher than watermark threshold or flooding time overtime threshold value, execution in step (6);
