A heat-conducting fin can be provided on one side of the semiconductor refrigeration sheet, and the second heat-dissipating fan 27 is in contact with the heat-conducting fin to facilitate heat transfer.

[0030] A dust cover 115 is provided at the lower part of the air inlet 113. A filter layer can be provided inside the dust cover 115 to prevent dust from entering the control box 1 and affecting the service life.
