The invention discloses a kind of clean prompting method of indoor machine filter screen of embedded type air conditioner, comprise with the next stage: the startup stage of air-conditioner; The sensor detection-phase; The prompting stage.The sensor detection-phase prompting stage comprises that pressure sensor starts, and pressure sensor begins test; Negative pressure preset value in testing result and the air outlet is compared, when test result during greater than negative pressure value the green indicating lamp on the decoration panel bright, and continue test again; When test result during less than negative pressure value the red led on the decoration panel bright, prompting needs the cleaning and filtering net.The invention has the beneficial effects as follows: air-conditioner starts the back by the negative pressure condition in the pressure sensor detection return air inlet, and show by the indicator lamp that is arranged on the decoration panel, timely cleaning and filtering net, not only effectively guaranteed the refrigeration of air-conditioner, but energy savings and significantly improve the heat exchange effect also simultaneously.

The clean prompting method of indoor machine filter screen of embedded type air conditioner

Technical field

The present invention relates to a kind of detachable air conditioner, particularly relate to a kind of clean prompting method of indoor machine filter screen of embedded type air conditioner.

Background technology

Usually air-conditioner is made up of heater, refrigeration machine, clarifier etc., can or purify for room air refrigeration or heating, for the user creates suitable indoor environment.

Air-conditioner generally can be divided into Saperated air conditioner and integral air conditioner.Saperated air conditioner and integral air conditioner have identical function.Saperated air conditioner is provided with the indoor set that can cool off/heat in the indoor, be provided with in the outside can heat/cool off and the off-premises station of compressor, and link off-premises station and indoor set with the refrigerant pipe.Air-conditioner outdoor unit is provided with condenser (outdoor heat converter) and compressor, is provided with evaporimeter (indoor heat converter) in the indoor set.

Indoor set need be hung on the wall or stand in the room, thus have seem with graceful interior decoration inharmonious and greatly degree taken the interior space; The off-premises station running noise is big, the dead of night particularly, and start, noise, the airflow noise of shutting down have difficulty in going to sleep the people; And, also existing the maintenance rate height, service life is short; Accuracy of temperature control is low, occurs sometimes hot and sometimes cold phenomenon sometimes; Air-conditioner is long-time use after, indoor air quality is poor, causes the shortcoming of " air-conditioner disease " etc.

The air-conditioner that has occurred being used for large-scale place or be used for family on the existing market, compare with the normal domestic use air-conditioner, air-conditioner has following characteristics: save the interior space, the residential central air conditioning device is installed, only a main frame need be installed on balcony at the most, in each room, install and embed the indoor set part on ventilating opening or the roof in each room, so saved indoor space; The air-conditioner system will deliver to different zones by cold (heat) amount that a main frame produces by hot water pipe or airduct, realize temperature, the humidity in a plurality of rooms are regulated; Indoor supply air temperature difference is little, and air quantity is big, and indoor temperature distribution is even, no air-conditioner dead angle; Unit adopts micro computer to control automatically, and each indoor set is start-stop separately all, and the temperature in each room can regulate separately and control as required voluntarily; Little power consumption, economical operation is energy-conservation; The air-conditioner easily worn part is few, advantages such as long service life.

Summary of the invention

Technical problem to be solved by this invention is, overcomes the prior art shortcoming, and a kind of clean prompting method that cleans the return air net according to how many automatically prompting users of dust is provided.

The technical solution adopted in the present invention is: the clean prompting method of indoor machine filter screen of embedded type air conditioner comprises with the next stage: the startup stage of air-conditioner; The sensor detection-phase; The prompting stage.

The described sensor detection-phase prompting stage comprises that pressure sensor starts, and pressure sensor begins test; Negative pressure preset value in testing result and the air outlet is compared, when test result during greater than negative pressure value the green indicating lamp on the decoration panel bright, and continue test again; When test result during less than negative pressure value the red led on the decoration panel bright, prompting needs the cleaning and filtering net.

The invention has the beneficial effects as follows: air-conditioner starts the back by the negative pressure condition in the pressure sensor detection return air inlet, and show by the indicator lamp that is arranged on the decoration panel, timely cleaning and filtering net, not only effectively guaranteed the refrigeration of air-conditioner, but energy savings and significantly improve the heat exchange effect also simultaneously.

Among the figure:

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:

The invention discloses a kind of embedded air-conditioner, comprising: fix, form the outward appearance of indoor set with the ceiling wall above it and be provided with the casing of exhaust outlet at sidewall; The inside that is arranged on casing is used for cooling off the heat exchanger of room air; Be used for drawing room air and indoor unlatching is transported to heat exchanger and cool off, then cold air blowed to indoor Air Blast fan; With the bottom surface that is arranged on casing and be formed with the front panel of air entry.

Fig. 2 is the panel schematic diagram that indicating device is installed on the decoration panel of the present invention; Fig. 3 is a detection of negative pressure flow chart in the return air inlet of the present invention.

As Fig. 2-shown in Figure 3, the clean prompting method of indoor machine filter screen of embedded type air conditioner of the present invention comprises: the startup stage of air-conditioner; Sensor detection-phase and prompting stage comprise the startup of pressure sensor, and pressure sensor begins test; At this moment, the negative pressure preset value compares in detected value and the air outlet, when test result during greater than negative pressure value the green indicating lamp on the decoration panel bright, screen pack normally need not to clean, pressure sensor continues test again; When detected value during less than negative pressure value the red led on the decoration panel bright, assembling on the screen pack has too much dust, influencing normal air conditioner refrigerating ability needs the cleaning and filtering net.

It is worthy of note; protection scope of the present invention is not limited to above-mentioned instantiation mode, and according to basic fundamental design of the present invention, those of ordinary skills need not through creative work; the embodiment that can associate all belongs to protection scope of the present invention.
