Description

Air conditioner indoor unit and air conditioner with the same

technical field

The utility model relates to the technical field of air conditioners, and more specifically relates to an air conditioner indoor unit. The utility model also relates to an air conditioner with the above-mentioned air conditioner indoor unit.

Background technique

In the process of air conditioning refrigeration, the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes a liquid refrigerant at room temperature and high pressure, so the outdoor unit blows out hot air. ; Then the liquid refrigerant enters the evaporator (indoor unit) through the capillary tube. Since the space suddenly increases and the pressure decreases after the refrigerant reaches the evaporator from the capillary tube, the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant. Thereby absorbing a large amount of heat, the evaporator will become cold, and the fan of the indoor unit blows the indoor air through the evaporator, so what the indoor unit blows out is cold wind; the water vapor in the air meets the cold evaporator It will condense into water droplets and flow out along the water pipe, which is why the air conditioner will leak water.

Please refer to accompanying drawing 1, this figure is the structural diagram of the air-conditioning indoor unit in the prior art when it is installed vertically upward; Disk 102, stepper motor 103, air outlet swing blade 104 and fan system 105. Because the water storage tray 102 is arranged on the bottom of the evaporator 101, the bottom end is the end of the evaporator 101 near the air inlet; The bottom surface of a water storage tank extends vertically, and the water droplets formed by the condensation of water vapor in the air will flow from the top to the bottom under the influence of gravity, so in order to ensure that the water droplets can flow into the water storage pan 102, the air conditioner indoor unit can only Install in two directions (horizontal direction and vertical upward direction), as shown in Figure 1 and Figure 2, the direction of the arrow in the figure is the flow direction of the wind; Figure 2 shows that the air conditioner indoor unit in the prior art is installed in the horizontal direction Schematic diagram of the structure. In the installation positions of the above two directions, when the indoor unit of the air conditioner is installed in the horizontal direction, the air outlet can blow out wind in any horizontal direction by adjusting the different positions of the indoor unit on the ceiling; when the indoor unit of the air conditioner is installed in the vertical direction When installed vertically, the air outlet of the indoor unit installed on the wall can only blow out vertically upward air.

In practical applications, due to the on-site installation environment and the needs of customers, it often happens that the air outlet of the indoor unit needs to blow out horizontal or vertical upward wind, and it may also happen that the air outlet of the indoor unit needs to blow out vertically downward wind. In this case, the indoor unit needs to be installed at the top of the wall so that the air outlet can blow out vertically downward wind; however, when the air conditioner indoor unit is installed vertically downward, the top of the evaporator 101 It will be located at the bottom, and the water droplets condensed in the air will flow to the top of the evaporator 101. Since the top of the evaporator 101 is not provided with a water pan, the air conditioner indoor unit cannot be installed in a vertically downward direction.

To sum up, it can be seen that the air conditioner indoor unit mentioned above cannot meet the installation requirement that the air outlet of the indoor unit blows out vertically downward wind, and furthermore cannot satisfy the air outlet of the indoor unit blowing out wind in any direction of horizontal direction, vertical upward direction and vertical downward direction. Installation requirements, poor versatility.

How to provide an air-conditioning indoor unit to meet the installation requirements of the air outlet of the indoor unit blowing out wind in any direction in the horizontal direction, vertically upward and vertically downward directions, so as to improve its versatility, is an urgent need for those skilled in the art. Solved technical problems.
