  Hereinafter, an embodiment in which the present invention is applied to, for example, a drum type washing and drying machine will be described with reference to the drawings. In FIG. 1, a main body 1 forming an outer shell of a washing / drying machine is provided with a door 2 for opening / closing a laundry inlet on the front side and a base plate 3 having a support leg 3a at the bottom. is there. In the main body 1, a water tank 5 that is elastically supported by a plurality of suspensions 4 is provided. In the water tank 5, a drum 6 that is a rotating tank rotates about a tilted horizontal axis (approximately the horizontal axis). Both are provided so as to be opposed to the door 2 (laundry input port).

As is well known, the drum 6 has a large number of small holes 7 on the peripheral wall. The water tank 5 includes a water tank body 8 and a water tank cover 9. The aquarium cover 9 has an annular shape as a whole, and is fitted and attached to the opening peripheral edge of the front surface of the aquarium body 8 so as to protrude inward in a bowl shape. The water tank cover 9 covers the front plate of the drum 6 and functions as a protective cover for the so-called rotating part.
In addition, a flexible bellows 10 is provided in a watertight manner between the front end of the water tank cover 9 and the back surface of the door 2 and the laundry inlet, thereby preventing water from splashing from the water tank 5 to the outside. Like to do. The drum 6 is directly rotated by an out-rotor type DC brushless motor 11 provided on the back side of the water tank 5.

  The water tank cover 9 integrally forms a hollow exhaust duct 12 that is a partial air passage region of the air passage with the auxiliary plate portion 9A. That is, the water tank cover 9 and the auxiliary plate portion 9A are integrally formed of synthetic resin. The water tank cover 9 is composed of a U-shaped member having a substantially U-shaped cross section, and the auxiliary plate portion 9A is configured of a lid plate-shaped member that closes an open portion of the U-shaped member. The water tank cover 9 and the auxiliary plate portion 9A are aligned at a predetermined position, and the part indicated by the symbol M in FIG. 5 is integrally joined through a joining means by friction welding to form an exhaust duct 12.

  As shown in FIGS. 2 and 3, the exhaust duct 12 includes a pair of left and right duct portions 12a and 12b that are branched left and right from the center portion of the annular lower end portion and divided at the upper end portion. In the duct portions 12a and 12b, as shown in FIGS. 2 to 4, suction ports 13, 14, and 15, 16 formed by arranging a plurality of hole groups on the inner peripheral surface 12R and the inner surface 12Q, which are different surfaces, are provided. Each is formed. The suction port 13 is configured to have a large opening area with respect to the suction port 14, and the suction port 15 is also configured to have a large opening area with respect to the suction port 16.

On the upper inner surface side of the water tank cover 9, a water supply cover 9a and an illumination lamp housing portion 9b are provided.
The inlets 13 to 16 correspond to one vent, and the outlet 17 (see FIG. 1) described below corresponds to the other vent. The air outlet 17 is formed on the back surface of the water tank 5, and the air outlet 17 communicates with the inside of the drum 6 through an air duct 18 and an air hole 19 formed on the back surface of the drum 6. Yes.

  The inlets 13 to 16 and the outlet 17 are communicated with each other outside the water tank 5 by a ventilation path 20 (indicated by an arrow 20 for convenience), and a drying device 21 serving as a drying means is provided in the middle of the ventilation path 20. Is provided. The ventilation path 20 includes the exhaust duct 12, an extendable joint 22, a duct 23a of an evaporator 23 as a dehumidifying means, a duct 24a of a condenser 24 as a heating means, a casing 25a of a blower 25 as a blowing means, An extendable joint 26 and a supply duct 27 are connected, and the supply duct 27 communicates with the air outlet 17.

  Accordingly, the water tank cover 9 constitutes a part of the exhaust duct 12 which is a partial region of the ventilation path 20 communicating with the suction ports 13 to 16. The evaporator 23 and the condenser 24 constitute a heat pump 28 together with a compressor and a capillary tube (not shown).

  The heat pump 28 is provided below the outside of the water tank 5. As is well known, a refrigerant is circulated in the order of a condenser 24, a capillary tube (throttle) (not shown), and an evaporator 23 by a compressor (not shown). In this configuration, during the drying operation, the circulating air is heated and warmed by the condenser 24, and the warm air is sent into the water tank 5 and the drum 6 through the supply duct 27 by the blower 25. This warm air contributes to the drying of the laundry, and is sucked and collected in the exhaust duct 12 through the suction ports 13 to 16. The warm air is cooled and dehumidified by the evaporator 23 and heated again by the condenser 24.

Further, the exhaust duct 12 has a width dimension which is gradually reduced as it goes from the blower 25 side toward the suction ports 13 to 16 (the upper width dimension Ha <lower width dimension Hb in FIGS. 1 and 2). Therefore, the flow path area is gradually reduced.
In FIG. 1, a drain hose 29 connected to the bottom of the water tank 5 is capable of draining outside the machine via a drain valve (not shown), and for draining dehumidified water cooled and condensed by the evaporator 23. A drainage means (not shown) is provided.

Next, the operation of the washing / drying machine having the above configuration will be described.
In the drum type washing and drying machine, when a standard driving course is selected and set, the drum 6 is speed-controlled by a control device (not shown) as is well known, and each process of washing, rinsing, dewatering and drying is automatically performed. To be executed.
Accordingly, the drying process in which the drying device 21 functions will be described. The drum 6 containing the laundry is rotated at a low speed, and the air heated by the condenser 24 of the heat pump 28 is heated by the rotational drive of the blower 25. Then, the air flows through the ventilation path 20 in the direction of the arrow, and is supplied to the inside of the drum 6 in the water tank 5 from the outlet 17 on the back surface of the water tank 5. The warm air comes into contact with the laundry in the drum 6 to take away moisture, and thus a drying action is performed. The warm air (exhaust air) after contributing to the drying is sucked into the exhaust duct 12 from the suction ports 13 to 16 on the front side as air containing a lot of moisture.

  In particular, the warm air that has passed through the drum 6 is mainly sucked by the suction ports 13 and 15, and the warm air that has exited from the small holes 7 of the drum 6 is mainly sucked by the suction ports 14 and 16. The hot air sucked into the exhaust duct 12 in this way is transferred to the lower evaporator 23 side. Thereafter, as described above, cooling and dehumidification is repeated by the evaporator 23 and heating by the condenser 24 is repeated.

  According to the present embodiment, since the water tank cover 9 of the water tank 5 constitutes a part of the exhaust duct 12 of the ventilation path 20 communicating with the suction ports 13 to 16, the existing water tank 5 is originally provided. The exhaust duct 12 of the ventilation path 20 can be formed using the water tank cover 9, and the number of parts of the components of the ventilation path 20 can be reduced and simplified.

  In addition, according to the present embodiment, the exhaust duct 12 of the ventilation path 20 is configured by fixing the auxiliary plate portion 9A to the water tank cover 9, so that packing or the like is used unlike the joining configuration such as screwing. Therefore, the exhaust duct 12 having high sealing performance can be configured. In this case, since the water tank cover 9 is composed of a U-shaped member in cross section and the auxiliary plate portion 9A is composed of a lid plate-shaped member that closes the open portion of the U-shaped cross-section member, the flow is generally rectangular in cross section. A path can be easily formed.

  Further, according to the present embodiment, the exhaust duct 12 constituted by the water tank cover 9 is formed with the suction ports 13 to 16 on a plurality of surfaces, so that it is compared with the configuration in which the suction ports are formed only on one surface. Large ventilation area can be secured. In particular, in addition to the inner peripheral surface 12R of the duct portions 12a and 12b, the suction ports 14 and 16 are formed in the inner surface 12Q, so that the hot air discharged from the small holes 7 of the drum 6 can be recovered satisfactorily.

  Further, since the exhaust duct 12 has a flow passage area that decreases from the blower 25 side toward the suction ports 13 to 16, the warm air suction effect can be enhanced. That is, since the suction ports 13 to 16 are suction ports when viewed from the blower 25, the exhaust duct 12 is narrowed toward the suction ports 13 to 16, and the suction ports 13 to 16 are formed. The suction speed is high, the suction effect is improved, the circulation efficiency of hot air is improved, and the drying efficiency is improved.

  Furthermore, according to the present embodiment, the water tank 5 is disposed so as to open substantially laterally, the drum 6 is disposed so as to be rotatable about the horizontal axis, and the dehumidifying means and the heating means are disposed below the water tank 5. Since the suction ports 13 to 16 are formed in the upper part of the water tank 5, the effect of configuring the exhaust duct 12 with the water tank cover 9 is extremely large. That is, for example, when the exhaust duct from the suction port to the heat pump is formed as a separate member from the aquarium cover of the aquarium, the exhaust duct does not interfere with the loading and unloading of laundry on the front of the aquarium. In this embodiment, the suction port 13 to 16 is at the upper part of the water tank 5 and the heat pump is required to be led to the lower heater pump through the outer surface. Since the exhaust duct 12 is configured by the water tank cover 9 in the positional relationship that 28 is located outside the water tank 5, the water tank cover 9 can be effectively used as the exhaust duct 12 as it is, and the exhaust duct routing configuration can be simplified. Can contribute.

In addition, according to the present embodiment, the pair of left and right duct portions 12a and 12b are provided with the suction ports 13 to 16 in a pair of left and right forms. However, a sufficient flow path can be secured, the exhaust duct 12 can be made thin, and the hot air can be satisfactorily sucked regardless of whether the drum 6 is rotated left or right.
In addition, the suction port 13 on the inner peripheral surface of the water tank 5 is configured to have a larger opening area than the suction port 14 on the rear surface, and the suction port 15 on the inner peripheral surface of the water tank 5 is also the suction port 16 on the rear surface. Therefore, the suction flow rate at the suction ports 13 and 15 on the inner peripheral surface of the water tank 5 opening is large, so that a hot air flow that passes through the drum 6 without leakage can be steadily formed. , Hot air circulation efficiency can be increased.

In addition, this invention is not limited to the said Example, You may implement as changed as follows. Chi words, the hot air is supplied from the water tank opening side may be configured to suction (exhaust) from the water tank back portion.
