Problems solved by technology

[0002] The prior art split floor air conditioner indoor unit mainly has a motor wind wheel system at the bottom to supply air upwards, and then blows out from the upper part of the air conditioner indoor unit through the indoor unit heat exchanger and sends it to the room. On the upper part of the air conditioner, the circulating air is directed downward to the lower space of the room through the air deflector. This structure has a certain effect when the air conditioner is cooling, because the cold air itself sinks, and people do not need it. Send cold air to the foot position very close to the floor; but when the air conditioner is heating, this structural form plays a lesser role: 1), because the hot air with a higher temperature is sent upward after being sent out of the air outlet For sports, it is difficult to use the wind deflector to direct the hot air obliquely downward to a position very low from the ground; 2), because the sensitive part of people's perception of heat is in the feet, as long as the feet are warm, the whole body will feel warm , so the indoor unit of the air conditioner needs to send the hot air to a position very close to the floor; 3) If the indoor unit of the air conditioner guides the hot air obliquely downward to the lower space of the room through the air deflector, the hot air will blow to the face of the person , which will make people feel uncomfortable and greatly reduce the comfort of the air conditioner
[0003] At the same time, when the conventional floor-standing air conditioner is heating, the hot air mainly floats up on the upper floor of the room, which is basically more than 2 meters, and the space for people to move in the room is mainly below 2 meters, so the heat floating on the upper floor of the room is basically a waste. , resulting in a great waste of energy

specific Embodiment 2

[0042] When the indoor mechanism of the air conditioner is heated, the upper switch door of the air outlet grille on the upper front panel is opened, and the lower switch door of the left outlet grille on the lower front panel is also opened, and at the same time, the fan speed of the upper volute fan and the lower volute fan are adjusted. The rotation speed of the upper volute fan is adjusted and controlled so that the fan speed of the upper volute fan is lower than the fan speed of the lower volute fan, so that the air enters from the left inlet grille of the upper front panel and the right inlet grille of the upper front panel, and passes through the indoor unit. After the heater, most of the hot air is sent out from the left outlet grille of the lower front panel, and a small part of the hot air is sent out from the outlet grille of the upper front panel, which ensures that most of the hot air is sent to the lower space of the room, and can also Taking care of the demand fo...

specific Embodiment 3

[0043] When the indoor unit of the air conditioner is cold, the upper switch door of the outlet grille on the upper front panel is opened, the lower switch door of the left outlet grille on the lower front panel is closed, and at the same time, the upper volute fan is controlled to open, and the lower volute fan is turned off. At this time, the indoor air enters from the left air intake grille of the upper front panel, the right air intake grille of the upper front panel, and the forward air grille of the upper front panel. Sending out, all the circulating cold air is directly sent to the upper space of the room, so that the cold air sinks to lower the temperature of the lower room, which improves the comfort of the air conditioner.

specific Embodiment 4

[0044] When the indoor unit of the air conditioner is cold, the upper switch door of the air outlet grille on the upper front panel is opened, and the lower switch door of the left outlet grille on the lower front panel is also opened, and at the same time, the speed of the upper volute fan and the lower volute fan are electronically controlled. The transfer of the fan is adjusted so that the speed of the upper volute fan is greater than that of the lower volute fan, so that the air enters from the right inlet grille of the upper front panel, and after passing through the heat exchanger of the indoor unit, most of the hot air flows from the upper front The air outlet grille of the panel is sent out, and a small part of hot air is sent out from the left air outlet grille of the lower front panel and the right air outlet grille of the lower front panel, which ensures that most of the cold air is sent to the upper space of the room, and can also take care of The demand for heat in...

Abstract

The invention discloses an air conditioner indoor unit capable of supplying air up and down and a control method thereof. The air conditioner indoor unit comprises an air conditioner casing, wherein an upper volute fan and a lower volute fan are arranged up and down and side by side in the casing, an upper air inlet and an upper air outlet are arranged on the upper volute fan, a lower air inlet and a lower air outlet are arranged on the lower volute fan, the upper air inlet and the lower air inlet are oppositely arranged on the side portion of the upper volute fan and the side portion of the lower volute fan respectively and are connected with a casing air inlet grille, heat exchangers are arranged between the air inlet grille and the upper air inlet and between the air inlet grille and the lower air inlet, and the upper air outlet and the lower air outlet extend to an upper air outlet grille of the casing and a lower air outlet grille of the casing respectively and are connected to form an induced air channel. By the aid of the air conditioner indoor unit and the control method, high efficiency refrigeration and heating with low wind are achieved, the hot air can be easily sent to the bottom space of a room, the comfort of an air conditioner is improved, and the use ratio of the heating capacity of the air conditioner is also improved, so that energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the field of floor-standing air conditioners, and in particular relates to an indoor unit of an air conditioner with upper and lower air supply ports and a multi-mode control method thereof. .
