Desktop air conditioner

Abstract

The invention provides a desktop air conditioner. The desktop air conditioner comprises a first centrifugal fan, a second centrifugal fan, a refrigerating and heating device and a shell. The refrigerating and heating device is provided with a semiconductor chilling plate, is fixedly arranged above the first centrifugal fan and the second centrifugal fan and is configured to allow heat exchange to be carried out between first airflow and a first varying temperature surface of the semiconductor chilling plate and between second airflow and a second first varying temperature surface of the semiconductor chilling plate, and therefore the temperature is changed. The first centrifugal fan, the second centrifugal fan and the refrigerating and heating device are surrounded by a cavity in the shell; a first air inlet communicated with a first air inlet area is formed in the lower portion of the front side face of the shell; a first air outlet from where the first airflow is blown out is formed in the upper portion of the front side face of the shell; a second air inlet communicated with a second air input area is formed in the lower portion of the rear side face of the shell; a second air outlet from where the second airflow is blown out is formed in the upper portion of the rear side face of the shell. According to the desktop air conditioner, due to the adoption of the two centrifugal fans and the refrigerating and heating device, cold air or hot air can be blown out; in addition, the desktop air conditioner is large in air output, small in size and low in noise.

Description

technical field [0001] The invention relates to a semiconductor air conditioner, in particular to a desktop air conditioner. Background technique [0002] Small desktop fans generally can only blow out natural wind at the same temperature as the room temperature, and cannot change the temperature of the wind. Therefore, when cooling is required, the desktop small fan cannot achieve a good cooling effect; when heat is needed, the desktop small fan is idle because it cannot generate hot air. [0003] In addition, although a household air conditioner can generate cold or hot air, it cannot be placed on a desktop or moved around due to its large size, which is not convenient enough to use. Therefore, household air conditioners are difficult to install and use in indoor desks or smaller spaces. Contents of the invention [0004] An object of the present invention is to provide a small desktop air conditioner that can provide cold or hot air. [0005] A further object of the ...

[0002] Small desktop fans generally can only blow out natural wind at the same temperature as the room temperature, and cannot change the temperature of the wind

Therefore, when cooling is required, the desktop small fan cannot achieve a good cooling effect; when heat is needed, the desktop small fan is idle because it cannot generate hot air

[0003] In addition, although household air conditioners can generate cold or hot air, they cannot be placed on the table or moved around due to their large volume, which is not convenient enough to use.

Therefore, household air conditioners are not easy to install and use in indoor desks or small spaces.
