As a further improvement on the present invention, described control module so arranges: described control module is controlled generation washing information according to the washing procedure of washing machine.
As a further improvement on the present invention, described display unit so arranges: described display unit shows described washing information.
The invention allows for a kind of control method of household electrical appliance, these household electrical appliance comprise display unit; Detecting unit, for producing detection signal when detection people is near household electrical appliance; And control module, be connected with described detecting unit with described display unit, its this control module so arranges: when described control module receives the detection signal from described detecting unit, described control module is opened described display unit or made described display unit in open mode; When described control module is not received the detection signal from described detecting unit in Preset Time, described control module is closed described display unit.
As the further improvement of this control method invention, described Preset Time is at least 30 seconds or between 30 seconds to 5 minutes.
Compared with prior art, the invention has the beneficial effects as follows: solved in prior art when people leaves at short notice and approaches household electrical appliance, the problem that household electrical appliances display screen is repeatedly closed and opened at short notice, extended the serviceable life of display screen, facilitate again user to check the duty of household electrical appliance simultaneously.
The present invention can be applicable on various suitable household electrical appliance.But the washing machine of below only take is described the specific embodiment of the present invention as example.
[accompanying drawing explanation]
Fig. 1 is the simplified diagram of washing machine;
[embodiment]
As shown in Figure 1, washing machine 10 comprises a shell, and this shell comprises an end face, ，Liang Ge side, a bottom surface, a back side, and a front 11.In most cases, each face of shell is made by the metal material of conduction, or other each faces are made by metal material except end face.Except bottom surface and the back side are difficult for being touched, other each faces all have by user, touched may.On the front 11 of washing machine 10 shells, there is magazine region 2,1, one, a guidance panel region, and door and grip area 3, user often will operate these regions as required.The washing machine of different styles or type is to the position of operating area and arrange different.For example, the guidance panel of some washing machine is positioned on end face, and for rotary drum washing machine, door and handle are often positioned on end face, and some washing machine does not have magazine etc.In addition, the shell of some washing machine is not regular hexahedron, for example, between end face and front, form the curved surface of a smooth transition, can also be some other irregular spatial structure.The embodiment of above-mentioned several washing machines shows in the accompanying drawings, but by above description can make those of ordinary skills can be beyond all doubt understand.In addition, other, at specifically described washing machine above, do not comprise washing machine, dryer, clothes washer-dryer, and other are suitable for washing machine of the present invention and also will be included in protection scope of the present invention.
In the guidance panel district 1 in washing machine front 11, be provided with washing machine procedure and select and the display unit 5 that starts compound keys 4 and work state of washing machine, display unit 5 can be the LCDs with touching function or light emitting diode (LED) display screen etc.In magazine district 2, be provided with magazine 6, user can place the washing agent of different purposes at this according to different clothing handling procedures.Door handle district 3 on washing machine is provided with for opening and closing the door of washing machine 7 of washings input port.Washing machine 10 is also built-in with detecting unit 8 and is attached thereto the control module 9 connecing, and detecting unit 8 is for producing detection signal and send to control module 9 near washing machine 10 time people being detected; Control module 9 is all connected with detecting unit 8 with display unit 5, and when control module 9 receives the detection signal from detecting unit 8, control module 9 is opened display unit 5 or made display unit 5 stay open state; When control module 9 is never received the detection signal from detecting unit 8 in Preset Time, 9 of control modules are closed display unit 5.This Preset Time is at least 30 seconds, and best setting-up time section is between 30 seconds to 5 minutes.
In the present embodiment, Preset Time can arrange realization by software also can arrange realization by hardware.On software, implementation is: the control module 9 in washing machine 10 is built-in with control program, by this control program, set Preset Time, this control program moves as follows: when control module 9 is not received the detection signal from detecting unit 8 in Preset Time, control module 9 is controlled display units 5 and closed.On hardware, implementation is: in household electrical appliance 10, be provided with timer (not indicating in figure), by this timer, set Preset Time, after Preset Time, timer sends timing signal to control module 9, and then control module 9 control display units 5 cut out.
In the present embodiment, control module 9 also produces washing information according to the washing procedure of washing machine 10, and display unit 5 is also for showing this washing information.
In the present embodiment, detecting unit 8 is non-contact inductive device, in particular for a kind of infrared sensor, for detection of before washing machine 10, whether someone exists.The feature of sensors with auxiliary electrode were is that it can detect the infrared radiation grade of object around, and the infrared heat variable quantity that around object emits is converted into electric signal.In general, sensors with auxiliary electrode were has three pins, is respectively grounding pin, power pins and output pin, and this sensor self also has two grooves, and each groove is made by the special material to sensitive for infrared radiation.When sensor is during in off working state, two grooves detect the same number of infrared radiations that go out from surrounding environmental radiation.When thermal man's body is passed by first groove section, to produce a positive variable signal, when leaving surveyed area second notch of passing by, thermal man's body will there is a reverse negative variable signal, thereby by amplifying circuit, these transducing signals amplified and by voltage comparator circuit, obtain the logic high of can Input Control Element 9 processing, when sensor signal is higher than positive reference voltage or all can export high level lower than negative reference voltage.In general, the situation that detecting unit 8 detects people has two kinds, and a kind of people of being exactly come in surveyed area and stop, also have a kind of people of being to pass by before surveyed area.
Set forth the control procedure of washing machine 10 in the present invention below: first start after washing machine 10, general display unit 5 opens demonstration, and detecting unit 8 and control module 9 are also started working.Whether detecting unit 8 ceaselessly has the concurrent detection signal that send of people to control module 9 before detecting washing machine 10, just controls display unit 5 and stay open state after control module 9 is received the detection signal that people detected.When detecting unit 8 detects washing machine 10 front nobody and after the lasting schedule time, be generally after at least 30 seconds, have people before still washing machine 10 not detected, 9 demonstrations of closing display unit 5 of control module, to save energy consumption.After this, detecting unit 8 continues to detect, and while having people before washing machine 10 being detected again, detecting unit 8 sends to control module 9 detection signal that people detected again, and control module 9 reopens the demonstration of display unit 5 immediately.
Various embodiments described above and shown in the drawings, only for the present invention is described, are not of the present invention whole.In the category of basic fundamental thought of the present invention, any type of change that the those of ordinary skill of correlative technology field carries out for the present invention all protection scope of the present invention it.
