Abstract
A dryer with a heat pump that includes a cabinet, a drum installed within the cabinet, and an exhaust duct configured to exhaust air from the drum to outside of the cabinet. The dryer also includes a fan configured to inhale air from the drum and pump the air to the exhaust duct, an evaporator configured to exchange heat with air being exhausted through the exhaust duct, and a condenser disposed at a rear side of the drum. The dryer further includes an intake passage member configured to guide air that has passed through the condenser into the drum and a compressor and an expansion apparatus configured to define a heat pump along the evaporator and condenser.
Claims16
A dryer, comprising:
- a cabinet;
- a drum installed within the cabinet and that includes an opening that is configured to receive objects to be dried;
- an exhaust duct configured to exhaust air from the drum to outside of the cabinet;
- a fan configured to inhale air from the drum and pump the air to the exhaust duct;
- an evaporator configured to exchange heat with air being exhausted through the exhaust duct;
- a condenser disposed behind a rear side of the drum that is opposite of a front side of the drum in which the opening is defined;
- an intake passage having an inlet configured to inhale air that has passed through the condenser into the drum;
- a compressor and an expansion apparatus configured to define a heat pump along with the evaporator and condenser;
- and
- a plate member located at the rear side of the drum and that is configured to define the intake passage,
- wherein the inlet is provided at a lower portion of the plate member to face a rear surface of the drum,
- wherein the condenser is mounted on the plate member through the inlet, and
- wherein a heater is mounted on an upper portion of the plate member to further heat air that has been heated by the condenser.
A dryer, comprising:
- a cabinet;
- a drum installed within the cabinet and that includes an opening and that is configured to receive objects to be dried;
- a condenser installed behind a rear side of the drum that is opposite of a front side of the drum in which the opening is defined, the condenser being configured to heat air inhaled from a rear surface of the cabinet;
- a fan disposed under a lower side of the drum and configured to inhale and exhaust air within the drum;
- a fan housing that accommodates the fan and communicates with the drum;
- an evaporator housing coupled to the fan housing and configured to guide the exhausted air out of the cabinet;
- a compressor housing disposed at one side of the evaporator housing;
- an evaporator accommodated in the evaporator housing and configured to exchange heat with air being guided by the evaporator housing;
- a compressor accommodated in the compressor housing;
- an intake passage having an inlet configured to inhale air that has passed through the condenser into the drum;
- a plate member located at the rear side of the drum and configured to define the intake passage, and
- a pair of fixing brackets fixed to the evaporator housing or compressor housing respectively, and configured to support the plate member,
- wherein the inlet is provided at the plate member to face a rear surface of the drum, and
- wherein the condenser is mounted on the plate member through the inlet, and
- wherein the plate member is disposed to face the rear surface of the drum.
