Vertical air conditioner

Abstract

The invention discloses a vertical air conditioner. The vertical air conditioner comprises an indoor unit which comprises a front panel, a back panel and left and right side panels. An internal air channel of the indoor unit is defined by the front panel, the back panel and the left and right side panels. A mixed air outlet is opened in the front panel, and a non heat exchange air inlet is opened in a position of the back panel, which is corresponding to the mixed air outlet. A blocking plate for opening or closing the non heat exchange air inlet is arranged at the non heat exchange air inlet. According to the vertical air conditioner, the blocking plate for opening or closing the non heat exchange air inlet is introduced at the non heat exchange air inlet on the back panel of the vertical air conditioner, and requirements of different users and different requirements of the same user are met.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a vertical air conditioner. Background technique [0002] In existing vertical air conditioners, the air inlet of the indoor unit is usually arranged below the front panel and / or side panel of the air conditioner, and the air outlet is arranged above the front panel of the air conditioner. The indoor air enters the air conditioner from the air inlet, and blows to the heat exchanger under the action of the centrifugal fan. After heat exchange by the heat exchanger, heat exchange air is formed, and the heat exchange air is blown out into the room from the air outlet. The air volume sent from the air outlet of the air conditioner depends entirely on the air volume of the air inlet of the air conditioner and the power of the centrifugal fan. It cannot increase the air volume by itself, the air supply volume is limited, and it does not significantly affect the fl...

Problems solved by technology

[0005] However, since the air inlet for introducing additional non-heat exchanging air on the back panel is an open structure, there are the following disadvantages: The air volume is adjusted, so the ratio of heat exchange air and non-heat exchange air contained in the mixed air sent by the air outlet cannot be adjusted. Therefore, the air volume and outlet air temperature cannot be adjusted according to individual differences of users, and the scope of application is narrow.

Secondly, from the perspective of user habits and temperature comfort, in the cooling mode, it is hoped that the colder heat-exchanging air can be mixed with some of the higher-temperature non-heat-exchanging air and then blown out; while in the heating mode, it is not expected The heat-exchanging air is mixed with non-heat-exchanging air with a lower temperature, that is, the demand for whether to inhale non-heat-exchanging air is different under different working modes of the air conditioner, and the air inlet with an open structure cannot meet the needs of users in cooling and heating. Requirements for use in working mode

Thirdly, the rear air inlet of the open structure is easy to give users the illusion that the cooling or heating speed of the air conditioner is slower than that of the traditional air conditioner without the rear air inlet, which in turn affects the user's trust in this type of air conditioner and reduces the user experience.
