Indoor unit of air conditioner

Abstract

An air-conditioner indoor unit is configured to be capable of changing the direction of an airflow that is blown out through a blow-out port. The air-conditioner indoor unit includes a control unit that switches between a normal mode and a wide mode. The control unit extends at least vertically a range that is to be reached by the airflow in an air-conditioning target space in the wide mode compared with the normal mode and causes the air conditioning capacity of the wide mode to be lower than the air conditioning capacity of the normal mode.

1 . An indoor unit of an air conditioner, the indoor unit being configured to be installed in an air-conditioning target space and to be capable of changing a direction of an airflow that is blown out through a blow-out port, the indoor unit comprising:
 a control unit configured to switch between a normal mode and a wide mode,   wherein the control unit is configured to extend at least vertically a range that is to be reached by the airflow in the air-conditioning target space in the wide mode compared with the normal mode and to cause an air conditioning capacity of the wide mode to be lower than an air conditioning capacity of the normal mode.   
     
     
         2 . The indoor unit of an air conditioner according to  claim 1 ,
 wherein the control unit is configured to switch to the normal mode when the wide mode has been continued for a predetermined period or more during cooling.   
     
     
         3 . The indoor unit of an air conditioner according to  claim 1 ,
 wherein the control unit is configured to switch between the normal mode and the wide mode based on presence/absence of a person inside and outside of a range that is to be reached by the airflow of the wide mode in the air-conditioning target space.   
     
     
         4 . The indoor unit of an air conditioner according to  claim 2 ,
 wherein the control unit is configured to switch between the normal mode and the wide mode based on presence/absence of a person inside and outside of a range that is to be reached by the airflow of the wide mode in the air-conditioning target space.   
     
     
         5 . The indoor unit of an air conditioner according to  claim 1 , the indoor unit further comprising:
 a heat exchanger that is configured to exchange heat with air that is taken in from the air-conditioning target space to thereby regulate a temperature of the air,   wherein the control unit is configured to cause a temperature of at least a portion of the heat exchanger in the wide mode during cooling to be lower than a dew temperature in the air-conditioning target space.   
     
     
         6 . The indoor unit of an air conditioner according to  claim 2 , the indoor unit further comprising:
 a heat exchanger that is configured to exchange heat with air that is taken in from the air-conditioning target space to thereby regulate a temperature of the air,   wherein the control unit is configured to cause a temperature of at least a portion of the heat exchanger in the wide mode during cooling to be lower than a dew temperature in the air-conditioning target space.   
     
     
         7 . The indoor unit of an air conditioner according to  claim 3 , the indoor unit further comprising:
 a heat exchanger that is configured to exchange heat with air that is taken in from the air-conditioning target space to thereby regulate a temperature of the air,   wherein the control unit is configured to cause a temperature of at least a portion of the heat exchanger in the wide mode during cooling to be lower than a dew temperature in the air-conditioning target space.   
     
     
         8 . The indoor unit of an air conditioner according to  claim 1 ,
 wherein the control unit is configured to vary a blow-out velocity of the airflow in the wide mode.   
     
     
         9 . The indoor unit of an air conditioner according to  claim 2 ,
 wherein the control unit is configured to vary a blow-out velocity of the airflow in the wide mode.   
     
     
         10 . The indoor unit of an air conditioner according to  claim 3 ,
 wherein the control unit is configured to vary a blow-out velocity of the airflow in the wide mode.   
     
     
         11 . The indoor unit of an air conditioner according to  claim 5 ,
 wherein the control unit is configured to vary a blow-out velocity of the airflow in the wide mode.
