Portable air conditioner

A portable air conditioner comprising:

• a housing having an internal space;
• a heat exchanger provided in the internal space and heat-exchanged with external air introduced from the outside;
• a blower fan configured to generate a negative pressure in the internal space so that the external air is introduced, the blower fan allowing the heat-exchanged external air to move upward;
• a discharge port configured to guide the upwardly guided external air to the outside of the housing;
• a temperature sensor configured to measure a temperature of the external air;
• an accommodation part provided inside the housing to accommodate the temperature sensor;
• a communication groove configured to allow the accommodation part and the internal space of the housing to communicate with each other so that the external air moves into the internal space of the housing via the accommodation part;
• and
• an inner casing provided inside the housing and connected to the blower fan,
• wherein the inner casing comprises:
• a front surface of which one side is recessed to define the accommodation part;
• a rear surface angled at a predetermined angle with respect to the front surface and disposed to face the internal space of the housing;
• and
• a front discharge passage adjacent to the accommodation part and configured to guide the external air introduced by the blower and to the outside of the front surface,
• wherein the communication groove passes through an inner surface of the accommodation part and the rear surface;
• wherein the housing comprises a front inclined panel configured to cover the front surface of the inner casing, and wherein the front inclined panel comprises:
• a first through-hole configured to define the discharge port;
• and
• a second through-hole communicating with the accommodation part and disposed adjacent to the first through-hole.
