Description of drawings
Fig. 1 is a washing machine structure sketch map of the present invention;
Fig. 2 is a control module sketch map of the present invention.
As depicted in figs. 1 and 2, washing machine 1, capacitive proximity sensors 2, control module 3, loudspeaker 4, speech trigger circuit 5, casing 6, high-frequency generator 7, gate 8, the tube 9 that is filled with water, clothing tube 10, motor 11, supply channel 12, discharge pipe line 13.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As depicted in figs. 1 and 2, washing machine 1 comprises casing 6, gate 8, be filled with water tube 9, clothing tube 10, driving and control system, and gate 8 is positioned at the front of casing 6; The tube 9 that is filled with water is fixed in the casing 6 through hitch, is the cylindrical shape of opening towards gate 8, and clothing tube 10 is installed in the tube 9 that is filled with water; Open clothing that gate 8 just can input will be washed in clothing tube 10 or with its taking-up; 11 rotations of drive systems motor, for pulsator washing machine, motor 11 just can drive the impeller rotation in the clothing tube 10; For tumbling-box washing machine; Motor 11 just can drive 10 rotations of clothing tube, thus the clothing in the washing clothes tube 10, whole washing process of control system control washing machine.
Washing machine tube 9 the top that is filled with water is connected to supply channel 12, is used in the tube 9 that is filled with water, infeeding the required washings of washing, and the bottom of the tube 9 that is filled with water is connected to discharge pipe line 13, and discharge pipe line 13 is to be used for when a washing process finishes, will being filled with water washings discharge in the tube 9.
The user is when needs are washed; At first open gate 8, in clothing tube 10, drop into the clothing that needs washing, drop into washing powder in the washing powder input port on being located at supply channel 12 then; The energized switch; From the casing 8 lip-deep setup units that are located at washing machine a kind select operating mode according to washings, the instruction of input start-up operation, the control system of washing machine 1 promptly begins to control whole operating process.
Supply channel 12 supplies water in the tube 9 that is filled with water, reach the water level of setting after, washing machine 1 just can begin washing procedure, after washing operation is accomplished, be filled with water tube 9 just through following discharge pipe line 12 with the washings discharge, and then implementation dehydrating operations.
Carried out behind the official hour at dehydrating operations, in the tube 9 that is filled with water, added new water through supply channel 12 once more, begun to carry out rinse operation.
After the rinse operation of having carried out the stipulated time, carry out dehydrating operations again, said process repeatedly is all over last powered-down switch, end operation to all laundry operations processes.
The washing process of washing machine 1 is all accomplished by control system control automatically, and the present invention has increased and is used for human body near, and the system of suitably reminding according to the operation of washing machine procedure.
This detection system for prompting comprises at least one capacitive proximity sensors 2, and it is arranged on the casing 6 of washing machine 1, be used for human body near and change its electrostatic capacitance.Capacitive proximity sensors 2 is the electrostatic capacitance at the two poles of the earth with detecting electrode and ground connection; As user during near detecting electrode, the influence of voltage on the examined electrode, and produce polarization phenomena; The user is more near detecting electrode; Electric charge on the detecting electrode increases, because the electric capacity and the electric charge of detecting electrode are directly proportional, the electric capacity of detecting electrode increases thereupon.
Capacitive proximity sensors 2 is connected to the high-frequency generator in the control module 3; Be electrically connected between capacitive proximity sensors 2 and the high-frequency generator; When the user near washing machine 1; When making the electric capacity of the detecting electrode in the capacitive proximity sensors 2 increase, the vibration of high-frequency oscillating circuits is weakened, even the failure of oscillations.The variation of the vibration of high-frequency oscillating circuits and the two state of failure of oscillation converts switching signal into through the testing circuit in the control module 3, and outwards exports signal.
The switching signal of being sent by testing circuit is transferred to the speech trigger circuit; Connect loudspeaker 4 through the speech trigger circuit,, the user is sent different voice remind explanation according to the program of washing machine operation; The speech trigger circuit is a prior art, just is not described in detail here.
Detecting electrode in the capacitive proximity sensors 2 is the metallic plate of conduction, is arranged on casing 6 inside of washing machine 1, and is fixed on the casing 6, can perhaps fix through screw through the mode of clamping.
Detecting electrode in the capacitive proximity sensors 2 also can be a kind of electroconductive resin, can be fixed on the surface of casing 6, as the part on casing 6 surfaces.
In order to detect the human body from different directions, capacitive proximity sensors 2 is arranged on the front or side of washing machine 1 casing 6, also can be positive and the side all be provided with; And be provided with a plurality of; If one of them damages like this, other all right operate as normal can not influence user's use.
Because capacitive proximity sensors 2 not only can respond to human body near and change electric capacity; Other object or animal also can change its capacitance; So for fear of moving owing to other object or animal; And let the system for prompting misoperation of washing machine 1, the detecting electrode of capacitive proximity sensors 2 is arranged on the higher position of washing machine 1, generally with the detecting electrode of capacitive proximity sensors 2 be placed on bottom apart from washing machine 1 more than 0.5 meter to the position between washing machine 1 most significant end.
As stated, in conjunction with accompanying drawing and the given scheme content of embodiment, can derive the similar techniques scheme.In every case be the content that does not break away from technical scheme of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical scheme of the present invention according to technical spirit of the present invention.
