Abstract
The utility model relates to a touch-type electronic lock for an air-conditioner, which comprises a push-button circuit, wherein, each button of the push-button circuit is arranged on a control panel of the air conditioner. The utility model is characterized in that the touch-type electronic lock for an air-conditioner also comprises a reset/ quartz-vibrator circuit, an electronic-switch button arranged below the control panel of the air conditioner, and a liquid crystal display circuit. The touch-type electronic lock for an air-conditioner also comprises a display which respectively accepts the signal of the push-button circuit and the electronic-switch button and locks or unlocks each button of the push-button circuit after detection, analysis and judgment, and the display controls the liquid crystal display circuit according to the input information. The touch-type electronic lock for an air-conditioner also comprises a driving compressor and the microprocessor UPD of the outdoor draught fan and the outdoor draught fan. When the operating state of the air conditioner is assured, each function button on the control panel of the air conditioner can be locked by a key through the electronic-switch button. The utility model has the advantages of simple, convenient and direct-viewing operation, and good human-computer interaction interface.
Description
The utility model relates to the point contact type electronic lock that a kind of air-conditioner is used.
At present, function on air-conditioner panel control button can at will be operated arbitrarily, when owner not the time or other reason, other people can arbitrarily change the duty of air-conditioner, its function control button does not have a locking device.
The purpose of this utility model provides the point contact type electronic lock that the air-conditioner of the function control button on a kind of lockable air-conditioner panel is used.
In order to achieve the above object, the utility model is achieved in that it comprises a key circuit, and each button of key circuit is located on the control panel of air-conditioner; It is characterized in that: it comprises that one resets/crystal oscillating circuit; One is located at the electronic switch button under the air-conditioner control panel; One liquid crystal display circuit; One receive the signal of key circuit and electronic switch button respectively and it is detected, analyzes, judges after again each button of key circuit is locked or non-locking, when unlock state can, remove to control the microprocessor UPD of LCD L demonstration, drive compression machine, indoor fan and the outdoor fan of liquid crystal display circuit according to the information of key circuit input.The model of microprocessor UPD is 753108.Reset/crystal oscillating circuit is by resetting block U1, crystal oscillator XT, and resistance R 5, resistance R A, resistance R B, capacitor C 4-C6 forms; The model of resetting block U1 is 34064.On the control panel of air-conditioner, be provided with a keyhole, the electronic switch button be located at keyhole below.
The utility model compared with prior art has following advantage:
1, after the duty of air-conditioner was determined, available key was by each function button on the electronic switch press key locking air-conditioner control panel;
2, simple to operation, directly perceived, human-computer interaction interface is good.
Fig. 1 is a circuit block diagram of the present utility model;
Fig. 2 is an air-conditioner control panel schematic diagram;
Fig. 3 is circuit theory diagrams of the present utility model.
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, it comprises a key circuit (2), and each button of key circuit (2) is located on the control panel (6) of air-conditioner; Comprise that one resets/crystal oscillating circuit (1); One is located at the electronic switch button (3) under the air-conditioner control panel (6); One liquid crystal display circuit (5); One receive the signal of key circuit (2) and electronic switch button (3) respectively and it is detected, analyzes, judges after again each button of key circuit (2) is locked or non-locking, when unlock state, can remove to control the microprocessor UPD (4) of LCD L demonstration, drive compression machine, indoor fan and the outdoor fan of liquid crystal display circuit (5) according to the information of key circuit (2) input.Reset/crystal oscillating circuit (1) microprocessor UPD (4) is resetted and the groundwork frequency is provided.
Shown in Fig. 2,3, the model of microprocessor UPD (4) is 753108.Reset/crystal oscillating circuit (1) by resetting block U1, crystal oscillator XT, resistance R 5, resistance R A, resistance R B, capacitor C 4 one C6 form; The model of resetting block U1 is 34064.On the control panel (6) of air-conditioner, be provided with a keyhole (7), electronic switch button (3) be located at keyhole (7) below.Liquid crystal display circuit (5) comprises LCD L.During work, for example the LCD L of current air-conditioner shows the duty of air-conditioning: automatic mode, set 24 ℃, automatic wind, in key inserts keyhole (7), electronic switch button (3) is pressed, after microprocessor UPD (4) has detected this button and has pressed, earlier judge whether current air-conditioner is in the lock state, when if air-conditioner is in normal condition, lock all buttons on the air-conditioner control panel (6) immediately, bright with the red light emitting diodes LED that 63 pin of microprocessor UPD are electrically connected, all buttons in expression air-conditioner display floater (6) are locked, if air-conditioner does not all respond when at this moment having other button to press again, LCD L is constant still to be automatic mode, set 24 ℃, automatic wind has only and presses behind the electronic switch button key once more or the power down phenomenon occurs, the state that just unlocks, the duty that could regulate air-conditioner this moment.
