In this embodiment, the shape of the housing 100 is set to be circular. The interior of the housing 100 forms a cavity for accommodating the internal components of the air conditioner 10 (such as a fan, a heat exchanger 700, etc.). The one end of casing 100 has uncovered 110, uncovered 110 is circular uncovered 110, and air inlet subassembly 200 sets up in uncovered 110 department, is provided with air intake 210 on the air inlet subassembly 200, air intake 210 is linked together with the external world, and mainly used is the air inlet, and air-out subassembly 300 also sets up in uncovered 110 department, and air-out subassembly 300 has air outlet 311, air outlet 311 is linked together with the external world, mainly used air-out.
It should be noted that, the air inlet 210 and the air outlet 311 may be both in communication with the outside, i.e., the air flows into the housing 100 from the air inlet 210 and flows out of the housing 100 from the air outlet 311. Of course, in other embodiments, the air inlet 210 of the air conditioner 10 may also be the air inlet 311, and the air outlet 311 is used as the air inlet 210, in this embodiment, only the position of the fan assembly 500 in the housing 100 needs to be changed, and thus, redundant description is omitted herein. In this regard, since the air inlet assembly 200 is sleeved on the air outlet assembly 300, the peripheral side of the air inlet assembly 200 is smaller than the peripheral side of the air outlet assembly 300, in order to further improve the air outlet effect and the air outlet volume of the air conditioner 10, the air outlet 311 is optionally arranged on the air outlet assembly 300, and when the air outlet 311 is arranged on the air outlet assembly 300, the area of the air outlet 311 is larger, and the air outlet effect is better.
The air inlet assembly 200 is sleeved on the air outlet assembly 300, the air inlet assembly 200 and the air outlet assembly 300 are arranged at the opening 110, and the air inlet assembly 200 and the air outlet assembly 300 cover the opening 110 so as to seal the opening 110. In order to ensure the reliability of the air inlet and outlet, the inner wall of the air outlet assembly 300 is attached to the inner wall of the air inlet assembly 200, so as to avoid air leakage. The air outlet assembly 300 has a protruding portion 310 protruding from the front side of the housing 100, the air outlet 311 is disposed on the peripheral side of the protruding portion 310, and the air outlet assembly 300 is movably disposed at the opening 110, so that the opening direction of the air outlet 311 can be switched to be set up or set down. The air inlet assembly 200 is movably disposed at the opening 110 and is sleeved by the air outlet assembly 300, the air inlet 210 can be completely blocked by the inner wall of the protruding portion 310, and when the air conditioner 10 works, the air inlet assembly 200 moves, so that the air inlet 210 is exposed from the inner wall of the protruding portion 310 and air from outside enters. The air intake assembly 200 may be moved in a swinging manner, a rotating manner, or a lifting movement of the air intake assembly 200 relative to the air outlet assembly 300, so long as the air intake 210 is exposed from the inner wall of the protruding portion 310 and air can enter.
The air conditioner 10 of the present invention has three modes of a cooling mode, a heating mode and an off/standby mode, and is specifically as follows:
Referring to fig. 9, when the air conditioner 10 is in the cooling mode, the air inlet assembly 200 and the air outlet assembly 300 of the air conditioner 10 rotate so that the opening of the air inlet 210 is downward, the opening of the air outlet 311 is upward, and in this mode, the air conditioner 10 is fed with air from the bottom and is discharged from the top, and cold air is blown out from the air outlet 311 disposed upward into a room. Because the density of the cold air is large, the air flow is easy to sink, so the cold air blown to the upper layer of the indoor can slowly sink, the whole rapid refrigeration of the indoor environment is realized, the efficiency during refrigeration is improved, and meanwhile, the loss of electric energy can be reduced.
Referring to fig. 10, when the air conditioner 10 is in the heating mode, the air inlet assembly 200 and the air outlet assembly 300 of the air conditioner 10 rotate so that the opening of the air inlet 210 is upward and the opening of the air outlet 311 is downward, in which mode the air conditioner 10 is fed with air from the top and is discharged from the bottom, and hot air is blown out from the downward air outlet 311 into a room. Because the density of the hot air is smaller, the air flow is easy to rise, so the hot air blown to the indoor lower layer can slowly rise, thereby realizing the whole rapid heating of the indoor environment, improving the efficiency during heating and reducing the loss of electric energy.
Referring to fig. 11, when the air conditioner 10 is in the off/standby mode, the air inlet assembly 200 and the air outlet assembly 300 of the air conditioner 10 rotate so that the opening of the air inlet 210 and the opening of the air outlet 311 are both disposed towards the same side, in this mode, the air inlet 210 is blocked by the inner wall of the protruding portion 310, the air inlet 210 cannot be fed, and the air conditioner 10 does not work. At this time, since the air inlet 210 is blocked by the inner wall of the protruding portion 310, the air inlet 210 is not communicated with the outside, and therefore, dust in the air and the like cannot fall into the air inlet 210, and dust accumulation at the air inlet 210 can be effectively avoided. Preferably, when the air conditioner 10 is in the off/standby mode, the opening of the air inlet 210 and the opening of the air outlet 311 are both downward, so that dust accumulation at the air outlet 311 can be prevented.
Therefore, through the cooperation of the air inlet assembly 200 and the air outlet assembly 300, the air flow direction of the air conditioner 10 can be switched, and the air conditioner 10 can have different air outlet modes in different modes, so that the air conditioner 10 can achieve good working effects in a refrigerating mode and a heating mode.
The up-down direction refers to a vertical direction of the air conditioner 10 when the air conditioner is in normal use, the left-right direction refers to a direction of two sides perpendicular to the up-down direction, and the front-back direction refers to a direction of the air conditioner 10 facing the user and facing away from the user after the air conditioner 10 is installed.
The air conditioner 10 of the present invention includes a housing 100, an air intake assembly 200, an air outlet assembly 300, and an air duct 400. One end of the housing 100 has an opening 110; the air inlet assembly 200 is movably arranged at the opening 110, and an air inlet 210 is arranged at the periphery of the air inlet assembly 200; the air outlet assembly 300 is movably disposed at the opening 110 and is sleeved with the air inlet assembly 200, the air outlet assembly 300 has a protruding portion 310 protruding from the front side of the housing 100, and an air outlet 311 is disposed on the peripheral side of the protruding portion 310; the air duct 400 is formed in the housing 100, and the air duct 400 communicates with the air inlet 210 and the air outlet 311; wherein the air intake assembly 200 is movable such that the air intake 210 is blocked or opened by the inner wall of the boss 310.
