Abstract
An air conditioner internal unit filter blockage alarm device relates to the air conditioning technology. Aiming at the problem that a filter screen is blocked by a large amount of dust in the use process of the existing air conditioner, so that the refrigeration effect is reduced, the filter blockage alarming device of the air conditioner indoor unit, which has a simple structure and adopts a temperature sensor to alarm, is provided. The technical scheme is that a thermistor TR is embedded in a heat exchanger 312, a thermistor TR is clamped on a bracket of the internal machine controller 125; thermal resistance TR12 and a resistance R4、R3A CPU of a single chip connecting machine chip inputs a point; thermistor TR25 and a resistance R2、R1Connecting the CPU of the single chip to input another point; series resistor R at output end of single chip CPU5And the other output end of the alarm B is connected with R in series6And a light emitting display assembly LED.
Description
Technical field
The utility model relates to the air conditioner technology, especially a kind of air-conditioning internal machine plugged filter warning device.
Technical background
Air conditioner in use owing to contain a large amount of dusts, material and other impurity in the air, causes the screen pack of the filtration of indoor apparatus of air conditioner latch up phenomenon to occur, makes intake reduce, and causes the refrigeration of air conditioner to descend; Sticking to simultaneously has a large amount of harmful bacterias on the dust on the screen pack, air quality is caused very big pollution, is unfavorable for user's body health; Make the operation of air conditioner time extend, problems such as waste electric power resource.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, utilize air-conditioning filter net when intercepting plug, intake occurs and reduce, the cold air on evaporator can't in time be taken away, cause temperature reduction on the heat exchanger, the air-conditioning internal machine plugged filter warning device that adopts temperature sensor to report to the police.
Technical scheme that the purpose of this utility model adopts is, the interior machine drain pan device that includes air-conditioning internal machine has heat exchanger and interior machine controller, thermistor TR
1, temperature-sensitive resistance TR
2, singlechip chip CPU, luminous display assembly LED, alarm B, resistance R, it is:
A: be embedded with thermistor TR between the copper pipe of heat exchanger

5Other end device B taking alarm input end, alarm B output head grounding;
F: singlechip chip CPU exports another terminating resistor R
6One end, resistance R
6Other end sending and receiving light display module LED input end, luminous display assembly LED output head grounding.
The utility model principle of work: when the indoor heating system evaporator has frosting or air inlet that obstruction is arranged, at this moment blower fan is subjected to the influence of air intake resistance, and its air quantity that blows out relatively just weakens, and screen pack is owing to the absorption of dust is stopped up, cause intake to lower, cause poor refrigerating efficiency.For in time getting rid of, remind the dust on user's cleaning filter net; Utilize existing control program, on the basis of original anti-freeze program, increase the function of reminding user's cleaning function to report to the police, the difference when promptly utilizing anti-freeze and screen pack to stop up between the temperature of living in just utilizes pilot lamp, display unit, hummer to point out.That is:
When CPU collects pipe temperature sensor temperature≤when setting temperature, environmentally sensitive actuator temperature 〉=25 degree centigrade; The CPU processor is protected system, such situation more than continuous appearance repeatedly, and CPU sends the luminous demonstration flicker of instruction-LED, the B hummer sends chimes of doom, needs to clean to remind the user filtering net.Thermistor TR wherein
1Gather the refrigeration system temperature, thermistor TR
2Gather environment temperature.
The utlity model has simple and compact for structure, make easy to assembly, characteristics such as its effect is obvious.
