DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for drying laundry by dehumidifying indoor air, such as a dehumidifier.

[0002]

2. Description of the Related Art Conventionally, as an air conditioner of this type, an evaporator and a condenser are provided inside a main body case behind an intake port as described in JP-A-7-239135 (F241 / 02). There is known a dehumidifier in which a vessel and a blower fan are sequentially arranged, and further below, a drainage tank and a compressor are arranged. The dehumidifier configured as described above takes in humid air into the room from the intake port by driving the blower, dehumidifies with the evaporator, heats the dehumidified cold air with the condenser, blows out the air from the exhaust port, and performs laundry. Etc. can be dried.

[0003] However, with the above-described configuration, the air heated by the condenser passes through the blower and is blown out from the exhaust port, so that the warmed air passes through the blower. During the winter, there is a problem that the drying time of the laundry or the like is prolonged because the indoor air is cold especially in winter.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner that blows warm air from an exhaust port without lowering the temperature of air heated by a condenser as much as possible.

[0005]

According to the present invention, there is provided a refrigeration cycle including a compressor, an evaporator, a condenser, a blower and the like in a main body, and a ventilating air passage extending from an intake port formed in the main body to an exhaust port. An air passage for discharging dehumidified and dried indoor air to be discharged and dried by the evaporator and the condenser is provided, and the condenser is formed by a straight portion and a bent portion communicating with the straight portion and bent in an L shape, The indoor air is discharged by passing through a bent portion from a straight portion of the condenser.

[0006] With the above structure, the room air taken in from the intake port is cooled and dehumidified by the evaporator, heated by the linear portion of the condenser, passed through the blower, and then heated again by the bent portion. It is blown out from the exhaust port. Therefore, the air whose temperature has decreased while passing through the blower is heated again and is blown out, so that when the laundry or the like is placed near the exhaust port, the dehumidified warm air hits the laundry or the like in a short time. Can be dried.

Further, the condenser is arranged such that the bent portion is located on the exhaust port side, so that the air reheated at the bent portion of the condenser can efficiently reach the exhaust port. A well-flowing air path is formed, so that the air reheated at the bent portion can be blown out in a warm state without lowering the temperature, and the laundry or the like can be dried in a shorter time.

[0008] Further, the bent portion is disposed so as to be located in an air passage to the exhaust port, so that the air reheated at the bent portion of the condenser reaches the exhaust port. Further, an air passage that flows efficiently is configured, and the air reheated at the bent portion can be blown out in a warm state without further lowering the temperature.

Further, the refrigerant condensed by the compressor is fed into the bent portion of the condenser and then sent out from the straight portion, so that the temperature of the refrigerant is increased by being compressed. When the refrigerant is first sent to the bent portion, the bent portion has a higher temperature than the straight portion, and the room air passes through the high-temperature bent portion immediately before being blown out from the exhaust port, thereby providing warmer air. , The laundry can be efficiently dried in a shorter time.

Further, the blower is disposed below the bent portion of the condenser. Therefore, the blower is disposed by utilizing a space formed below the bent portion.
The main body can be downsized. Further, when the air is blown out by the blower, the air is immediately heated by the bent portion, so that the warm air can be efficiently blown out.

Further, the refrigerant which has been compressed by the compressor 26 and has a high temperature is first sent to the bent portion 16b, so that the bent portion 16b is
Since the temperature is higher than that of the
Warm air can be blown out by passing through the bent portion 16b having a high temperature immediately before being blown out of the washing machine, and the laundry and the like can be efficiently dried in a short time.

The blower 19 is provided with the condenser 16
By arranging it below the bent portion 16b, the space formed below the bent portion 16b can be effectively used, so that the main body 1 can be downsized. Further, when the air is blown out by the blower 19, the air is immediately warmed by the bent portion, so that there is an effect that the warm air can be efficiently exhausted.

[0039]

According to the first aspect of the present invention, the condenser is formed of a straight portion and a bent portion communicating with the straight portion and bent in an L shape, and the indoor air is bent from the straight portion of the condenser. The room air taken in from the exhaust port is cooled and dehumidified by the evaporator, and then heated by the straight part of the condenser, passes through the blower, and then is bent again. It is heated in the section and is blown out from the exhaust port. Therefore, when the laundry or the like is placed near the exhaust port by heating and blowing out the air whose temperature has decreased while passing through the blower, the laundry or the like is shortened by the dehumidified warm air. It has effects such as being able to be dried in time.

According to the second aspect of the present invention, since the condenser is arranged so that the bent portion is located on the exhaust port side, the air reheated at the bent portion can efficiently reach the exhaust port. A flowing air path is formed, and is blown out in a warm state without lowering the temperature of the air reheated at the bent portion, so that it is possible to dry laundry and the like in a shorter time. .

According to the third aspect of the present invention, the bent portion is disposed so as to be located in the air path to the exhaust port, so that the air reheated at the bent portion of the condenser is discharged to the exhaust port. An air passage that flows to the mouth more efficiently is formed, and the air reheated at the bent portion can be blown out in a warm state without further lowering the temperature.

According to the fourth aspect of the present invention, the refrigerant condensed in the compressor is sent to the bent portion of the condenser and then sent out from the linear portion, so that the refrigerant is compressed to increase the temperature. Since the temperature of the bent portion becomes higher than that of the straight portion when the refrigerant that has been first sent to the bent portion, the air flowing through the blower passes through the bent portion immediately before being blown out. By absorbing the heat higher than that of the linear portion and blowing it out at a higher temperature, the laundry and the like can be dried efficiently in a shorter time.

According to the fifth aspect of the present invention, since the blower is arranged below the bent portion of the condenser, the blower is arranged by making good use of the space formed below the bent portion. Accordingly, the main body can be reduced in size, and when the air is blown out by the blower, the body is immediately warmed by the bent portion, so that it is possible to efficiently blow out the warm air.
