Air is discharged after merging in an air trunk 7 passing a condensor 103. Then the heated air is obtained, where the dehumidification amount is adjusted. The adjustment of the air volume is controlled with a dehumidification degree, a passage time, an internal size of a room, a laundry drying degree, and a laundry amount, etc., as information. Thus the dehumidified air therefore is obtained in response to the situation. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a dehumidifying drier that performs cooling dehumidification and clothes drying using a refrigeration cycle.

  Conventionally, this type of dehumidifying dryer uses an internal heat exchanger (see, for example, Patent Document 1).

  Hereinafter, the dehumidifying dryer will be described with reference to FIG.

  As shown in FIG. 21, in the dehumidifying dryer 101, a compressor 102, a condenser 103, a squeezing device 104, and an evaporator 105 are connected in this order by a refrigerant pipe 106 to form a refrigeration cycle. The main body is a heat pump that cools and dehumidifies the air, and an internal heat exchanger 107 is disposed in the air path from the evaporator 105 to the condenser 103. In addition, the inlet 108 is configured to be able to switch the air path that bypasses the internal heat exchanger 107 and guides air to the evaporator 105.

In the dehumidifying dryer 101 configured as described above, the air flowing in from the inlet 108 enters the internal heat exchanger 107 and is precooled by exchanging heat with the air that has already been cooled and dehumidified by the evaporator 105, and then the evaporator. The case where the air is dehumidified through 105 and the case where the air flowing in from the inlet 108 bypasses the internal heat exchanger 107 and is dehumidified through the evaporator 105 are finally heated by the condenser 103. However, high-humidity air is not pre-cooled and low-humidity air is pre-cooled and dehumidified, so that efficient dehumidification can be achieved with a simple structure.

The main heat exchanger 107 is disposed in the air path from the evaporator 105 to the condenser 103. And the bypass air path C2 (5) of the internal heat exchanger 107 and the shunt damper C (1) for adjusting the diversion of the bypass air volume and the internal heat exchanger 107 air volume are provided.

  In the above configuration, the air flowing in from the indoor air inlet A (2) enters the internal heat exchanger 107 and is precooled by exchanging heat with the air that has already been cooled and dehumidified by the evaporator 105, so that the air path B (3) Then, it is led to the evaporator 105 and cooled and dehumidified by the evaporator 105. Thereafter, the air is diverted into the air passage C1 (4) and the bypass air passage C2 (5) guided to the internal heat exchanger 107 by the shunt damper C (1). The air flowing through the air passage C1 (4) passes through the internal heat exchanger 107 and is heated by exchanging heat with the air flowing in from the inlet A (2), and is guided to the condenser 103 through the air passage D (6). The air flowing through the bypass air passage C <b> 2 (5) is directly led to the condenser 103. The air that has passed through the condenser 103 and has been heated is blown into the room through the air path E (7).

  Changes in the air state of each part of the dehumidifying dryer acting in this way (inlet A → air path B → air path C1, bypass air path C2 → air path D → air path E) are shown in FIG. 2 and FIG. Shown on the diagram. FIG. 2 shows a case where the opening degree of the shunt damper C (1) is fully closed, that is, a case where air does not flow through the bypass air passage C2 (5). FIG. 3 shows a case where the opening degree of the shunt damper C (1) is halved, that is, a case where the air volumes of the bypass air passage C2 (5) and the air passage C1 (4) are made equal.

  The capacity of the internal heat exchanger 107 is reduced by opening the shunt damper C (1) and bypassing the internal heat exchanger 107 from FIGS. 2 and 3, and the absolute humidity is reduced in the air passage C1 (4) at the outlet of the evaporator 105.

A bypass air path D2 (13) of the condenser 103 and a shunt damper D (8) for adjusting the shunting of the bypass air volume and the condenser 103 air volume are provided.

  In the above configuration, the air flowing in from the indoor air inlet A (2) enters the internal heat exchanger 107 and is precooled by exchanging heat with the air that has already been cooled and dehumidified by the evaporator 105, so that the air path B (3) Then, it is led to the evaporator 105 and cooled and dehumidified by the evaporator 105. Then, the air passes through the air passage C (10) and is heated by the internal heat exchanger 107 by exchanging heat with the air flowing in from the inlet A (2). Thereafter, the air flows through the air passage D0 (11) and is divided into the air passage D1 (12) and the bypass air passage D2 (13) which are led to the condenser 103 by the shunt damper D (8). The air flowing through the bypass air passage D2 (13) is blown into the room as it is. The air flowing through the air passage D1 (12) is guided to the condenser 103, passes through the condenser 103, is further heated, and is blown out into the room through the air passage E (7).

When the damper (9) is synchronized, it is possible to obtain heated air whose humidity has been adjusted and air that has been appropriately dehumidified and cooled in accordance with the air volume distribution ratio.

  In the present embodiment, the air volume adjustment damper (9) is controlled in synchronization with the shunt damper D (8) so that the air volumes of the bypass air path D2 (13) and the bypass air path D3 (14) are equal. Although control may be performed regardless of the output of the shunt damper D (8), it cannot be said to be preferable for maintaining the stability of the refrigeration cycle.

  Further, in the present embodiment, the air volume adjustment damper (9) is controlled so that the air volumes of the bypass air path D2 (13) and the bypass air path D3 (14) are equal, but the bypass air path D2 (13) is bypassed. The reliability of the refrigeration cycle is improved by setting a larger air volume in the air path D3 (14).

Thereafter, the air is diverted into the air passage C1 (4) and the bypass air passage C2 (5) guided to the internal heat exchanger 107 by the shunt damper C (1). The air flowing through the air passage C1 (4) passes through the internal heat exchanger 107 and is heated by exchanging heat with the air flowing in from the inlet A (2), and is guided to the air passage D0 (11). The air flowing through the bypass air passage C2 (5) is directly led to the air passage D0 (11). Thereafter, the air is diverted into the air passage D1 (12) and the bypass air passage D2 (13) guided to the condenser 103 by the shunt damper D (8).
