Embodiment 1

In Fig. 1, the 1st, be contained in the various function operations of the control unit in the air conditioner, in this operating unit 1, be provided with as the run switch 2 that makes the operation of air conditioner on/off, continue to press and do not accept the locking switch that prevents maloperation 3 that other switching manipulation makes it to become lock-out state with regard to accepting this operation 3 seconds as the continued operation switch, be used to make the time switch 4 of air conditioner in the predetermined instant operation, the demonstration change-over switch 6 of the demonstration of conversion display unit 5, "+" configuration switch 7 and "-" configuration switch 8 of the displaying contents of change display unit 5.In addition, display unit 5 shows that by 4 bit digital the LED of usefulness constitutes, can change display setting temperature, room temperature equitemperature data and present moment, setting constantly etc. constantly data or month day etc. calendar data.

Fig. 2 is used to control the circuit diagram that ribbon gymnastics is made the air conditioner of panel.Each switch by the operating unit 1 that comprises run switch 2 is imported to microcomputer 9, so that the various functions that are included into air conditioner are controlled.The 11st, the resonant frequency of quartz (controlled) oscillator 10 as reference clock, to the moon, day, the time, branch and second data count, as the clock integrated circuit that the clock that has calendar function moves, it carries month, day moment data according to the requirement of microcomputer 9.Display unit 5 is connected with the outlet side of microcomputer 9 with the load group 12 who makes the air conditioner action.

Microcomputer 9 has function that the time of pressing continuously as the continued operation switch that prevents the locking switch 3 of maloperation is judged and to the locking switch 3 that prevents maloperation with the function judged of the state when showing that change-over switch 6 is pressed simultaneously.

Flowchart text action below with reference to Fig. 3.At first, when run switch 2 is connected (step 20), microcomputer 9 is presented on the display unit 5 (step 21) with the initial value of design temperature with by the detected room temperature of temperature sensor (not shown).

Then, transmit signal to load group 12 from the data (step 22) of clock with the data of reading calendar (month day) the integrated circuit 11 and present moment (time, minute, second); Then carry out the operation control (step 23) of air conditioner.In step 24, judge and show that whether change-over switch 6 is connected, and just changes displaying contents by step 25 when connecting.When temperature shows, just be transformed into present moment and show; When present moment shows, just be transformed into temperature and show.Fig. 4 (b) is the demonstration example of present moment 12:15.

Judge in step 26 whether

configuration switch

7,8 is connected, when connecting, by the displaying contents of step 27 change display unit 5.When temperature showed, when pressing "+" configuration switch 7, design temperature just once increased progressively by Celsius temperature, and when pressing "-" configuration switch 8, design temperature just once successively decreased.In addition, when present moment showed, when pressing "+" configuration switch 7, the position of " branch " increased progressively one minute by one minute, when pressing "-" configuration switch 8, " time " increase progressively one hour by one hour.

Then, judge to prevent whether the locking switch 3 of maloperation from connecting by step 28, under the connection situation, just judge by step 29 whether change-over switch 6 is connected, under the connection situation, just judge to prevent whether the locking switch 3 of maloperation from continuing for 3 seconds by step 30.If just disconnected with the interior locking switch 3 of maloperation that prevents at 3 seconds, then program rests on step 28 and does not do any processing.If continue to connect more than 3 seconds, then in step 31, make the switch motion that prevents wrong operation locking, after this forbid accepting the on off state input of operating portion 1.Equally by making the locking switch 3 that prevents maloperation press the function (not shown) that continues just can remove for 3 seconds the locking switch that prevents maloperation.The switch that why makes the switch 3 that prevents maloperation become continued operation is in order to make such as locking because of maloperation or causing that such thing that unlocks is unlikely to take place just when when locking easily because child is naughty etc.

When pressing 3 seconds of back at the locking switch 3 that prevents maloperation during with interior connection display switch 6, just enter step 32, make moon in the memory of microcomputer 9, day show that a timing begins, by step 33 display unit 5 is transformed into a month day demonstration.Fig. 4 (c) is the example that shows October 25.In showing, the day moon judges by step 34 whether

configuration switch

7,8 is connected, when disconnecting, judge month by step 35 day whether to show timing, return to original demonstration if just separate the demonstration of the day twelfth month of the lunar year when month day demonstration time surpasses 5 seconds by step 36 through 5 seconds.

Under the situation that configuration switch 7,8 is connected before the day moon, the demonstration time was less than 5 seconds, can show by step 37 a change month day.When "+" configuration switch 7 was pressed, the position of " day " per diem increased progressively, and the position of " moon " monthly increases progressively when "-" configuration switch 8 is pressed.In the moment of

configuration switch

7,8 connections, by carrying out the moon day demonstration in 5 seconds behind the step 38 removing demonstration timer again.

After this, in run switch continues turn-on time, repeat the processing of step 22.

Needing change month day data be when following situation, that is: when initial initializing set when power supply is inserted, exhaust with the stand-by power supply (not shown)s such as battery of integrated circuit 11 and when needing supply and when because ambient noise etc. when causing that the day moon, data changed when clock.Under the occasion of using as air conditioner, displays temperature or situation constantly are more in display unit 5 often, and show month situation of day seldom in addition.

Therefore, even realize showing that by pressing 2 special operationals such as switch simultaneously the low demonstration of frequency can not damage operating characteristics yet.Owing to usually show what an operation inversion temperature of change-over switch 6 showed and showed constantly, so, show that on the contrary Geng Ming Liao, operability are better.In addition when two switches are pressed, because wherein to have a switch at least is the continued operation switch, in 3 seconds, press another switch more simultaneously if press this switch earlier, then can not accept to press the function of switch earlier and show month day, therefore do not worry maloperation, thereby make easy to use.

After being presented at and automatically terminating for 5 seconds, the day moon just returns to original show state, owing to only in this time, could change displaying contents with configuration switch, so can not change month day data and think mistakenly to have changed season and remove to change correcting value, thereby can not operate under the uncomfortable room temperature because of maloperation.

Therefore, comprise according to display unit of the present invention: clock with calendar function, displays temperature information, the various function operations unit in the air conditioner has been included in the display unit of time information etc. and control in, this operating unit is by connection, disconnect the run switch of operation of air-conditioner, change the demonstration change-over switch of demonstration of above-mentioned display unit and the compositions such as configuration switch of displaying contents of the above-mentioned display unit of change, have at least one to be the received continued operation switch of ability after the certain hour ongoing operation in these switches, when a plurality of switches that comprise this continued operation switch are pressed simultaneously, because having made the demonstration of above-mentioned display unit be transformed into calendar shows, so can not accept the switching manipulation of other function in the time of on being transformed into the calendar demonstration, thereby realize a kind of do not worry maloperation and disply apparatus for air conditioner easy to use.

Calendar showed to be converted to original demonstration after the fixed time, only just may change calendar data by configuration switch in this calendar procedure for displaying, therefore can not change calendar data mistakenly, thereby had realized having the display unit of the air conditioner of high reliability.
