The embodiment of the invention provides an air conditioner with an air purification function, which comprises an outdoor unit and an indoor unit, as shown in fig. 1, the air conditioner is a schematic external structure diagram of the indoor unit in the embodiment of the invention, an air outlet 3 is arranged at the bottom of the indoor unit 1, an air inlet baffle 2 and a first air inlet 4 are arranged at the top of the indoor unit 1, an HEPA filter screen is arranged at the inner side of the first air inlet 4, indoor air is sucked into the indoor unit 1 from the first air inlet 4, filtered by the HEPA filter screen, heated or cooled by a heat exchanger in the indoor unit 1, and finally blown out through the air outlet 3. Floating dust in the HEPA filter screen can effective filtering air, reduces PM2.5 value, improves the air quality, but also can greatly increase the resistance of breathing in simultaneously, influences air conditioner air-out efficiency, leads to air conditioner operating power to strengthen, is unfavorable for energy-concerving and environment-protective.
As shown in fig. 2, which is a schematic structural diagram of the indoor unit in the embodiment of the present invention after the air inlet baffle is opened, the second air inlet 5 is covered below the air inlet baffle 2, the inner side of the second air inlet 5 is provided with an air inlet filter screen 21, the air inlet filter screen 21 is a common filter screen, the aperture of the common filter screen is obviously larger than that of the HEPA filter screen, the air inlet filter screen 21 has a general air impurity filtering capability, but has a small resistance, and can take air outlet efficiency and air conditioner energy consumption into consideration.
As shown in fig. 3, which is a schematic view of a connection structure according to an embodiment of the present invention, the air conditioner further includes a main controller, an air quality sensing unit, and an air quality purifying unit, which are disposed on the indoor unit 1, and the main controller is electrically connected to the air quality sensing unit and the air quality purifying unit, respectively. The basic working principle of the air conditioner is that the air quality sensing unit acquires current air quality data, the main controller automatically controls the air quality purification unit according to the acquired air quality data, the air quality purification unit is ensured to operate only when the air quality is poor, and the air quality purification unit stops operating when the air quality is good, so that the purposes of saving energy, protecting environment and prolonging the service life are achieved.
More specifically, the air quality sensing unit comprises a PM2.5 sensor, a TVOC sensor and a communication module which are respectively electrically connected with the main controller. Wherein, the PM2.5 sensor is used for measuring the value of the accessible lung particles in the indoor air. The TVOC sensor is used for measuring TVOC (Total Volatile Organic Compounds) in indoor air, wherein the TVOC refers to Organic matters with saturated vapor pressure of more than 133.32pa at room temperature, the boiling point of the TVOC is 50-250 ℃, the TVOC can exist in the air in the form of steam at room temperature, and the TVOC has toxicity, irritation, carcinogenicity and special smell, can affect skin and mucous membrane, and can cause acute damage to human body. TVOC mainly comes from fuel combustion and transportation outdoors, and mainly comes from decoration materials, smoking, cooking and the like indoors. The communication module can adopt communication chips such as wifi, bluetooth, 4G for local air quality information that real-time reception weather station issued. In order to improve the real-time performance of indoor air quality measurement, a PM2.5 sensor and a TVOC sensor can be installed on the inner side of the air outlet 3.
More specifically, the air quality purification unit comprises a baffle motor, an ultraviolet generator and a negative oxygen ion generator which are respectively and electrically connected with the main controller, the power output end of the baffle motor is in transmission connection with the air inlet baffle 2, and the air inlet baffle 2 can cover or open the second air inlet 5 under the driving of the baffle motor. The ultraviolet generator is used for generating ultraviolet light capable of killing bacteria, and the negative oxygen ion generator is used for generating negative oxygen ions capable of purifying air and being beneficial to body health.
The working process of the air conditioner of the invention is as follows:
the method comprises the following steps that firstly, an air conditioner power supply is connected, in an initial state, an ultraviolet generator and a negative oxygen ion generator are both in a closed state, an air inlet baffle 2 is opened, and because the air inlet resistance of an air inlet filter screen 21 is obviously smaller than that of an HEPA filter screen, an operation air duct of a second air inlet 5, the air inlet filter screen 21 and an air outlet 3 is formed in an indoor unit 1.
And step two, the main controller acquires current indoor air quality information through a PM2.5 sensor and a TVOC sensor in the air quality sensing unit, compares the acquired indoor air PM2.5 value with a preset PM2.5 threshold value, and compares the acquired indoor air TVOC value with a preset TVOC threshold value. If the PM2.5 value of the indoor air is greater than the PM2.5 threshold value, or the TVOC value of the indoor air is greater than the TVOC threshold value, as long as at least any one of the above two conditions is satisfied, it can be determined that the indoor air is poor and the air purification process by the air quality purification unit is required. The specific operation is as follows: the main controller sends a control instruction to the baffle motor, the baffle motor drives the air inlet baffle 2 to cover the second air inlet 5, at the moment, the indoor unit 1 is changed into a running air duct of a first air inlet 4, a HEPA filter screen and an air outlet 3, and the HEPA filter screen filters floating impurities in the air; meanwhile, the main controller sends control instructions to the ultraviolet generator and the negative oxygen ion generator, and the ultraviolet generator and the negative oxygen ion generator work to sterilize and disinfect air passing through the indoor unit 1. The PM2.5 threshold value and the TVOC threshold value can be preset to adapt to the use requirements of different users, the lower the threshold value is set, the more frequently the air quality purification unit operates, the higher the air purification quality is, and the higher the corresponding energy consumption is. In addition, the working sequence of the ultraviolet generator, the negative oxygen ion generator and the baffle motor can be preset according to the requirements of users so as to meet the requirements of different user groups. The user also can set up and receive meteorological information by communication module, carries out meteorological information propelling movement through cell-phone APP, and main control unit controls air quality purification unit according to the meteorological information of propelling movement.
And step three, when the PM2.5 value of the indoor air is not greater than the PM2.5 threshold value and the TVOC value of the indoor air is not greater than the TVOC threshold value, the indoor air quality condition is better, and air purification treatment is not needed, at the moment, the main controller sends a control instruction, the ultraviolet generator and the negative oxygen ion generator are closed, the baffle motor is driven to drive the air inlet baffle 2 to open the second air inlet 5, and the running air channel of the second air inlet 5, the air inlet filter screen 21 and the air outlet 3 is recovered.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
