[0003]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention
Dry air is sent from the dry air circulation passage 111 to the dehydration tank 105 for drying. The dry air that has passed through the dehydration tank 105 returns to the dry air circulation passage 111, and is repeatedly circulated by being sent from the dry air circulation passage 111 into the dehydration tank 105 again.

During this drying operation, the drying air sent into the dehydration tank 105 escapes to the water tank 103 side through the dehydration holes 113 provided in the dehydration tank 105.
For this reason, a so-called short circuit occurs in which the dry air flows between the dehydration tank 105 and the water tank 103, and there is a problem that the dry air cannot be effectively used and the drying efficiency is reduced.

Therefore, an object of the present invention is to provide a washer / dryer in which the drying air is allowed to efficiently flow in the dehydration tank.

[0006]

In order to achieve the above object, the present invention provides a water tank supported by a suspension in an outer box and a horizontal axis centered by a drive motor arranged inside the water tank. Is rotatably controlled as
A dehydration tank provided with a dehydration hole, a dry air intake port provided on one side of the dehydration tank, and a dry air circulation passageway through which the dry air flows while connecting and communicating with the dry air intake port provided on the other side, respectively. And a drying air blocking means for blocking the flow of the drying air between the dehydrating tank and the water tank through the dehydrating hole.

In a preferred embodiment of the drying air blocking means, the peripheral wall of the dehydration tank is tapered in cross section along the direction of the rotation axis, and a plurality of dehydration holes are provided near the maximum diameter of the tapered dehydration tank. .

Alternatively, the peripheral wall of the dewatering tank has a tapered cross-section along the direction of the rotation axis, and the dewatering outer peripheral wall having a plurality of dewatering holes in the vicinity of the maximum diameter of the tapered dewatering tank and the rotation axis center line. It is composed of a dehydration inner peripheral wall provided in parallel with a large number of dehydration holes.

Alternatively, the opening diameter of the dewatering holes is gradually increased from the dry air intake side to the dry air intake side.

Alternatively, a seal member is provided between the dehydration tank and the water tank on the dry air outlet side.

[0011]

According to such a washer / dryer, during the drying operation, the drying air from the drying air circulation passage is sent from the drying air inlet into the dehydration tank for drying. The dry air that has finished the work returns to the dry air circulation passage from the dry air outlet, and is repeatedly fed into the dehydration tank to repeat the circulation.

During this drying operation, the drying air blocking means blocks the flow between the dehydrating tank and the water tank, so that the drying air efficiently flows in the dehydrating tank and the drying is performed.

The dry air circulation passage 7 is formed by a duct 39, and has a blower 41, a dehumidifier 43, and a heater 4 inside.
5 are arranged respectively. One of the first connection ports 39 a of the dry air circulation passage 7 communicates with the dry air intake 17 of the dehydration tank 5. The other second connection port 39b is used for the dehydration tank 5
Is in communication with the dry air outlet 19 of
Has a shape that doubles as a loading / unloading opening for loading / unloading laundry when the opening / closing door 25 is opened.

The blower 41 is arranged in a region close to the second connection port 39b side, and the rotational power from the drive motor M is applied to the fan to force the dry air to flow as indicated by the arrow.

The dehumidifier 43 is arranged at a substantially middle portion of the dry air circulation passage 7 and functions to remove water from the dry air when passing through.

The heater 45 is arranged in a region near the first connection port 39a side, is controlled to a predetermined temperature by a control unit (not shown), and functions to generate dry air.

According to the washer / dryer constructed as described above, by rotating the dehydration tub 5 after the completion of washing, the dehydrated water is swung out to the peripheral wall side and the dehydration hole is smoothly formed by the tapered shape. The water is drained from the dehydration hole 21 toward 21.

Next, when the drying operation is started after the completion of the dehydration, the dry air generated by the heater 45 is dried air intake 1
It is sent into the dehydration tank 5 from 7 and dried. The dry air that has finished the work returns from the dry air outlet 19 into the dry air circulation passage 7. At this time, the dry air is removed by the dehumidifier 4
When passing 3, the water content is removed and the dry air intake 17 is again used.
The circulation from the inside to the dehydration tank 5 is repeated. During this drying operation, the dry air sent into the dehydration tank 5 escapes from the dehydration holes 21 to the water tank 5 side, but at the dry air outlet 19 side, and because the number is limited, The short circuit that affects the drying does not occur, and efficient drying is performed.

FIGS. 2 to 5 show another embodiment of the dry air blocking means 15.

That is, in the dry air blocking means 15 shown in FIG. 2, the dehydration tank 5 having a large number of dehydration holes 21 in the peripheral wall thereof.

Since this is the same as the embodiment described above, the same reference numerals are given and detailed description is omitted.

According to this embodiment, the dry air flowing between the dehydration tank 5 and the water tank 3 is prevented from short circuit by the seal member 47 rotating together with the dehydration tank 5 and the fixed seal member 49. As a result, efficient drying is possible.

The dry air blocking means 15 shown in FIG. 3, which is a modification of FIG. 1, has a tapered shape in which the peripheral wall of the dehydration tank 5 is raised toward the central portion, and the maximum diameter of the dehydration tank 5 is increased. A plurality of dehydration holes 21 are provided in the vicinity. Since the other constituent elements are the same as those in the embodiment of FIG. 1, the same reference numerals are given and detailed description thereof will be omitted.

According to this embodiment, the number of the dehydration holes 21 is limited to the vicinity of the maximum diameter, so that the escape of the drying air to the water tank 3 side can be suppressed to be small, and efficient drying can be performed. . In this case, a ring-shaped seal member 51 is provided on the outer peripheral wall on the dehydration tank 5 side, while a ring-shaped seal member 53 facing the seal member 51 is provided on the water tank 3 side, so that the efficiency is improved. Good dryness can be expected.
