Description

Technical Field

The present invention relates to a field of household appliances, in particular, to an air conditioner indoor unit.

Technical Background

In recent years, due to a rapid expansion of an economic scale and a rapid urbanization process, air pollution is becoming more and more serious, and perennial fog and haze weather has appeared in most cities in China. Increase of PM2.5 concentration directly leads to a frequent occurrence of the dust and haze weather and a sharp increase of toxic and harmful substances in fog, which has seriously threatened human health. In this case, a conventional and comfort household air conditioner cannot meet requirements of people, and health, comfort, and environmental protection have become development goals of modern air conditioners.
For an ordinary air conditioner, in order to ensure an air conditioning effect thereof, it is required that an air-conditioned room must be closed. As a result, indoor fine dust, smoke, bacteria, virus, and waste gas increase continuously, and oxygen content decreases continuously, so that air quality becomes worse and worse. In recent years, with people's increasing attention to an "air conditioning disease", it has begun to require people not to stay in an air-conditioned room for a long time, and to open windows to let in fresh air, or to supplement fresh air to the room by means of leakage through gaps between doors and windows under a negative pressure formed by indoor exhaust, so as to improve the indoor environment. Document CN106196358A discloses a fresh air all-in-one conditioner, and document CN 105485774A discloses a vertical air-conditioning indoor unit according to the preamble of claim 1.

The light emitting device is in a signal communication with the induction device, to receive air quality information detected by the induction device, and display light of a corresponding color according to the air quality information so as to inform a user of air quality at this time.
In an embodiment, the fresh air device 2000 further includes a fresh air housing 2100 in which a fresh air passage 2200 and a polluted air passage 2300 are provided. A fresh air inlet 2210 and a fresh air outlet 2220 communicating with the fresh air passage 2200 and a polluted air inlet 2310 and a polluted air outlet 2320 communicating with the polluted air passage 2300 are provided in the fresh air housing 2100.
In an embodiment, the fresh air device 2000 further includes a heat exchange core 2400 provided in the fresh air housing 2100, and the heat exchange core 2400 communicates with both the fresh air passage 2200 and the polluted air passage 2300 so that the fresh air in the fresh air passage 2200 and the polluted air in the polluted air passage 2300 exchange heat in the heat exchange core 2400. By combining an ordinary air conditioner with a total heat exchange, the fresh air may be introduced to renew the indoor air, and the indoor polluted air is discharged to improve air quality. The fresh air and the polluted air may exchange energy through a total heat exchanger to recover energy, thereby reducing an energy loss.
The air conditioner indoor unit of the present invention mainly includes two portions, i.e. an upper portion and a lower portion. The upper portion is the cooling and heating device 1000, and the lower portion is the fresh air device 2000. Assembly and disassembly of various parts of the air conditioner indoor unit are shown in FIGS. 8 to 17.
In an embodiment, the cooling and heating device 1000 includes an air intake panel portion 1100, an evaporator portion 1200, an air duct portion 1300, an air out frame portion 1400, and a top cover 1600.
In a specific implementation, as shown in FIGS. 4, 8-12, the air intake panel portion 1100 includes an air inlet panel and an air inlet filter screen.
In a specific implementation, the evaporator portion 1200 includes an evaporator, a side plate, an evaporator bracket, and a water receiving tray.
In a specific implementation, the air duct portion 1300 includes an air duct, a cross-flow fan, an air out panel, a sweeping blade, an air passage driving motor, and an air passage driving gear.
In a specific implementation, the evaporator portion 1200 is fixed to the air intake panel portion 1100 by upper, lower, left and right screws.
In a specific implementation, the air duct portion 1300 is fixed to the evaporator portion 1200 and the air intake panel portion 1100 by snaps provided at left and right sides.
In an embodiment, as shown in FIGS. 5 and 6, the fresh air device 2000 further includes a motor 2500, fresh air blades 2600, air exhaust blades 2700, a first filter screen 2800, and a second filter screen 2900.
In an embodiment, in the fresh air device, the motor 2500 drives the fresh air blades 2600 and the air exhaust blades 2700 to rotate, and indoor polluted air is discharged to the outdoors through the polluted air passage 2300 and the heat exchange core 2400. Outdoor fresh air is introduced into the indoors through the fresh air passage 2200, the first filter screen 2800, the heat exchange core 2400, and the second filter screen 2900. The polluted air and the fresh air exchange sensible heat and latent heat in the heat exchange core 2400.
For example, in summer, an outdoor air temperature is higher than an indoor air temperature, and the fresh air passes through the heat exchange core 2400, and part of energy is transferred to indoor polluted air and discharged from the indoors, thus achieving a cooling effect.
For example, in winter, an outdoor air temperature is lower than an indoor air temperature, and the fresh air absorbs part of energy from the polluted air through the heat exchange core 2400 to achieve an effect of increasing temperature.
In this way, it can be realized that a temperature of introduced fresh air is not too high or too low, thus avoiding causing a serious increase of load or human body discomfort after introduction of the fresh air. What's more, the polluted air discharged transfers part of energy to the fresh air or absorbs part of energy from the fresh air, thereby avoiding an energy waste.
In an embodiment, when the fresh air passes through the first filter screen 2800 and the second filter screen 2900, a cleaning effect can be achieved, thereby improving quality of indoor air. The fresh air blows upward and forward through the fresh air outlet 2220, and may be brought to farther locations by air blowing from a fan of the cooling and heating device 1000, thereby preventing the short circuit between the fresh air and the polluted air.
In an embodiment, please refer to FIGS. 18 to 24, the air conditioner indoor unit includes an air outlet structure connected to the fresh air device 2000. The air outlet structure includes an air baffle portion 70, an air out duct housing 60, and a moving portion 30.

The moving portion 30 moves in an extending direction of the receiving hole to drive the air baffle portion 70 to move between the first position and the second position, so as to close and block the receiving hole when the air baffle portion 70 moves to the first position, and separate the air baffle portion 70 from the receiving hole when the air baffle portion 70 moves to the second position, thereby allowing the air conditioner indoor unit to blow air through a gap between the receiving hole and the air baffle portion 70. By providing the air baffle portion 70 and the moving portion 30, and by arranging the moving portion 30 to move in the extending direction of the receiving hole, the air baffle portion 70 is driven to extend and contract. The moving portion 30 may drive the air baffle portion 70 to extend and contract conveniently and quickly.
