The embodiment of the present invention provides an air conditioner including an air conditioner indoor unit, and fig. 1 is an exploded schematic view of the air conditioner indoor unit, please refer to fig. 1.
The air conditioner indoor unit is a cabinet air conditioner with upper and lower air outlets, and comprises a shell, an upper fan assembly 12 and a lower fan 13, wherein the shell is provided with an upper air outlet 102 and a lower air outlet 105, the upper air outlet 102 is positioned at the top of the shell, the lower air outlet 105 is positioned at the bottom of the shell, the upper fan assembly 12 and the lower fan 13 are respectively installed in the shell, the lower fan 13 is positioned below the upper fan assembly 12, one part of air flowing through a heat exchanger 16 is discharged from the upper air outlet 102 through the upper fan assembly 12, and the other part of air is discharged from the lower air outlet 105 of the shell through the lower fan 13.
The air conditioner provided by the embodiment has two working conditions of heating and cooling, and according to the principle that cold air sinks and hot air rises, when the air conditioner is in the heating working condition, the upper air outlet 102 and the lower air outlet 105 of the shell simultaneously output air, or only the lower air outlet 105 of the shell outputs air, so that the effect that the hot air quickly falls to the ground is realized; when the air conditioner is in a refrigeration working condition, only the upper air outlet 102 is used for exhausting air, and the lower air outlet 105 of the shell is used for not exhausting air, so that cold air is not blown to people.
Because the existing air conditioner can not satisfy the comfort experience of the user due to the hot air blown out from the lower air outlet 105 of the shell in the heating condition.
Utility model people have studied the lower air outlet 105 cooperation relation of lower fan 13 and casing in to the air conditioning indoor set, and the hot-air of fan 13 is gone into down after the discovery is flowed through heat exchanger 16, can not realize the short distance after blowing off from the lower air outlet 105 of casing and falls to the ground for it is relatively poor to heat the effect.
In this embodiment, through setting up down fan 13 slope in the casing, and the air outlet of down fan 13 and the lower air outlet 105 intercommunication of casing, the one side that down fan 13 is close to the lower air outlet 105 of casing is less than the one side of keeping away from the lower air outlet 105 of casing to make the air-out direction slope of the lower air outlet 105 of casing downwards, hot-air slope blows off downwards when heating, thereby realizes that hot-air short distance falls to the ground, according to the ascending principle of hot-air, realizes the effect that the carpet formula heats.
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 2 is a cross-sectional view of an air conditioning indoor unit, and fig. 3 is a schematic structural view of the air conditioning indoor unit, as shown in fig. 1, fig. 2, and fig. 3.
The casing includes front panel 10, back boarding 11, top cap 14 and base 15, the mutual lock of front panel 10 and back boarding 11, and top cap 14 lid fits the top, and base 15 sets up in the bottom to enclose the synthesis and hold the chamber, go up fan subassembly 12 and lower fan 13 and set up respectively in holding the intracavity, and lower fan 13 is located the lower part of last fan subassembly 12.
The top of the front panel 10 is provided with an upper air outlet 102, the bottom of the front panel 10 is provided with a lower air outlet 105, the back panel 11 is provided with an air inlet 115, and air enters from the air inlet 115, passes through the heat exchanger 16, and is blown out from the air outlets through the fan assembly. In this embodiment, air entering the air conditioner from the air inlet 115 flows through the heat exchanger 16, a portion of the air is blown out from the upper air outlet 102 by the upper fan assembly 12, and a portion of the air is blown out from the lower air outlet 105 of the housing by the lower fan 13.
It can be understood that the upper air outlet 102 opened at the top of the front panel 10 may be a single air outlet, or may be a left air outlet and a right air outlet, which is determined according to the actual situation and is not limited specifically.
When the air conditioner is in the state of vertical setting, down fan 13 slope sets up in the casing, and the air that gets into in the air conditioner from air intake 115 flows through heat exchanger 16 after, and partly enters into down fan 13 from the axial, sends out from the air outlet of fan 13 down, blows off from the lower air outlet 105 of casing at last to shorten the distance of falling to the ground of hot-air, be favorable to the hot-air can fall to the ground fast, according to the hot-air principle that rises, thereby realize the carpet formula and heat, promote user's the comfort experience that heats.
It can be understood that the air outlet of the lower fan 13 is communicated with the lower air outlet 105 of the housing, and two ways of direct communication and indirect communication are included. The direct communication means that the air guide channel of the lower fan 13 is directly abutted against the position of the lower air outlet 105 formed on the front panel 10; indirect communication means that the air outlet of the lower fan 13 is communicated with the lower air outlet 105 of the housing through an intermediate transition element.
Fig. 4 is a partial enlarged view of a portion a in fig. 2, and specifically illustrates a structural schematic view of a direct connection between an air outlet of the lower fan 13 and the lower air outlet 105 of the housing, as shown in fig. 4.
