Said device includes reflective sensor mounted in the glass cover and in the inside of filter screen, sensor circuit mounted on the circuit board for inputting sensor detection signal into microcomputer, microcomputer mounted on the circuit board for receiving sensor signal and giving out control signal, buzzer drive circuit for receiving microcomputer control signal. LED display circuit and LED. Said invention also provides the concrete several stages of said prompting method.
Description
Technical field
The present invention relates to the air-conditioning technique field, more specifically say so and detect filter screen of air conditioner detection prompting attending device and the method that its cleannes also can be sent sound, light warning and show check result on the net automatically about being installed in air-conditioner filtering.
Background technology
Existing air-conditioner is generally sucked grid, is installed on the airstrainer that sucks in the grid, is installed in the screen pack compressor, expansion valve, gas-liquid separator, suction, the discharge fan of refrigerant evaporation or condensing indoor and outdoor heat exchanger, compression refrigerant and discharges grid and constitute by the air that is installed on machine shell panel.Its operation principle is: need thermoregulator room air under the effect of fan by sucking grid, airstrainer, entering in the air-conditioner, carry out discharging in indoor from discharging grid again after the heat exchange (heat absorption, heat release) with heat exchanger, such reciprocation cycle makes and indoorly reaches refrigeration or system is warm, but foreign material such as dust in air, villus fiber are constantly long-pending on screen pack builds precipitation because air reciprocation cycle in air-conditioner also makes, and circulation resistance increases, consumption rate rises, energy utilization rate reduces, conditioner efficiency reduces thereby make.Addressing this problem traditional method is that labor intensive material resources or long-term use do not remove to clear up screen pack no matter air-conditioner usage frequency, time and filtering net cleaning situation thereof are regularly pulled down cleaning without exception, so not only increases power consumption and makes the conditioner efficiency reduction also can damage air-conditioner.
The special flat 7-151173 of nineteen ninety-five Japan's special permission designation discloses a kind of air conditioner, it is provided with illuminating part in the one side of screen pack, in the in addition face of screen pack the variation that the light accepting part utilization sees through screen pack light is set and is transferred to light quantity detecting element and judegment part, testing result shows whether need to be serviced at last, but this transmission-type of screen pack is detected its problem that sensor installation is very inconvenient and existence is made dirty easily or damaged.
Summary of the invention
The object of the present invention is to provide the filter screen of air conditioner that damages a kind ofly be convenient to install, be difficult for making dirty to detect reminds attending device and method to solve the above-mentioned problem that exists.
The device of the present invention's technical scheme of dealing with problems includes in order to achieve the above object: the sensor that is installed on inboard its clean conditions of perception of filter screen of air conditioner; Be installed on the indoor set circuit board, be transferred to the sensor circuit of microcomputer after the conversion of sensor senses signal is amplified; Be installed on the interior receiving sensor circuit signal of indoor set and send the microcomputer of control signal according to it; Be loaded on circuit board and receive the buzzer drive circuit of microcomputer control signal with audible alarm; Be loaded on LED (light emitting diode) display of the control signal of indoor unit panel reception microcomputer output; Be installed on the LCD formation that receives microcomputer output control signal on the air-conditioning remote control panel and show the clean conditions of filter screen of air conditioner, it is characterized in that: the illuminating part of its sensor and light accepting part all are installed in the filter screen of air conditioner inner glass cover, utilize reflection sensor to make.
Detection of the present invention reminds maintaining method to include: air-conditioner key opening stage; Each power on/off of air-conditioner is judged the stage; Extinguish if the access failure power LED turn-offs, remote controller liquid crystal display " power supply disconnection " also returns to each class of preparation back; If each power connection, power LED is bright, begins to use the sensor detection-phase; Then be below filter screen of air conditioner whether dirty the judgement stage; If screen pack is dirty, the buzzer call in the microcomputer control buzzer drive circuit 10 seconds, light-emitting diode display flicker remote controller liquid crystal display simultaneously in 10 seconds " is cleaned this screen pack ", if screen pack is not dirty, then liquid crystal display " connection power supply " is remained in operation.
Advantage and good effect: compared following advantage with existing transmission-type filter screen of air conditioner checkout gear:
1. the illuminating part of detecting sensor of the present invention and light accepting part are all in the inboard air-conditioner inside of screen pack, institute is so that lead-in wire and install, and is not easy to damage, and illuminating part and light accepting part all concentrate in the cloche, occupation of land is few also to be difficult for making dirty, thereby can improve accuracy in detection.
2. sensor and circuit thereof, light-emitting diode display can be installed a plurality of by microcomputer control carrying out multiple spot detection demonstration.
