  However, in the conventional configuration, the air inside the dehydration tank is not replaced with the air outside the machine body during the dehydration operation, and the dehydration efficiency is limited.

  The present invention solves the above-described conventional problems, and provides ventilation openings in the inner lid and the outer lid, and exhausts the air inside the dehydration tank and sucks the outside air during the dehydration operation, thereby reducing the humidity inside the dehydration tank. In addition to the dehydration by centrifugal force, the object is to improve the dehydration efficiency by promoting the drying of clothing.

  In order to solve the above-described conventional problems, a two-tub washing machine according to the present invention includes a washing tub for washing clothes, a dewatering tub for dehydrating clothes and having an opening at the top, and an inner lid for opening and closing the opening. And an outer lid that covers the inner lid from above, and the inner lid and the outer lid are provided with ventilation openings that communicate the inside and outside of the dehydration tank.

  As a result, the air inside the dehydration tank is ventilated through the ventilation port, the moisture inside the dehydration tank is reduced, and the dehydration efficiency is improved by promoting not only dehydration by centrifugal force but also drying of clothes.

  The two-tank washing machine of the present invention ventilates the air in the dehydration tank through the ventilation port, thereby improving the dehydration efficiency by promoting not only dehydration by centrifugal force but also drying of clothes.

In addition to dehydration by centrifugal force, dehydration efficiency is improved by promoting drying of clothing.

  In the second invention, in particular, the ventilation port provided in the inner lid of the first invention has an intake port provided at a position corresponding to the vicinity of the center of the dehydration tank and a position corresponding to the vicinity of the outer periphery of the dehydration tank. With the configuration having the exhaust port provided, the air generated by the rotational movement of the dehydration tank can be efficiently ventilated in conjunction with the rotation of the dehydration tank.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description. Further, the present invention is not limited by this embodiment.

(Embodiment 1)
Fig.1 (a) is a top view of the outer cover of the two-tub type washing machine in embodiment of this invention, FIG.1 (b) shows the perspective view. Fig.2 (a) is a top view of the inner cover of the two tub type washing machine in embodiment of this invention, FIG.2 (b) shows the perspective view. FIG. 3 is a diagram showing a positional relationship between the dehydration tank and the ventilation opening in the embodiment of the present invention.

  Hereinafter, it demonstrates using FIGS. 1-4.

  Separately from the washing tub 1, the dewatering tub 6 is provided in the main body 100 so as to rotate about the vertical direction.

  An upper cover 5 for opening and closing the opening 8 and an outer cover 4 for covering the inner cover 5 from above are provided on the upper portion of the dewatering tank 6 that dehydrates clothes and has an opening 8 for putting clothes on the top. The inner lid 5 is provided on a dehydration receiving cover 7 provided on the upper portion of the dehydration tank 6, and the outer lid 4 is attached to the upper cover 2.

  An end portion of the inner lid 5 is rotatably supported by the dehydration receiving cover 7, and the inner lid 5 is closed during the dehydration operation, thereby preventing water scattering and ensuring the safety of the user.

  The end of the outer lid 4 is pivotally supported by the upper cover 2 so that the detection means (not shown) detects that the outer lid 4 is closed, and the outer lid 4 is closed. The safety of the user is ensured by the dehydration tank 6 rotating.

The inner lid 5 and the outer lid 4 are each provided with a ventilation port. The ventilation port 11 provided in the outer lid 4 is arranged corresponding to the vicinity of the outer periphery of the dehydration tank 6, and the intake port 9 and the exhaust port 10 are provided in the vicinity of the outer periphery of the dehydration tank 6 as ventilation ports provided in the inner lid 5. It is arranged at the corresponding position. The ventilation port 11 is provided close to the exhaust port 10.

  The ventilation port 11 is provided in the longitudinal direction of the main body 100 and has a configuration in which a plurality of ventilation holes are connected. The intake port 9 is composed of a plurality of vent holes extending radially from the substantially central portion of the dehydration tank 6, and the exhaust port 10 is a plurality of concentric circles extending along the outer periphery of the dehydration tank 6. Consists of vents.

  The operation will be described below.

  With the inner lid 5 and the outer lid 4 closed, the dehydration tank 6 is rotated at a high speed to perform the dehydration operation. As shown in FIG. 3, the dewatering tank 6 rotates in the direction of the arrow. In conjunction with the rotation of the dewatering tank 6, a suction force is generated at the substantially central portion of the opening 8 of the dewatering tank 6 by centrifugal force. With this suction force, outside air is sucked from the air inlet 9 provided in the inner lid 5 toward the inside of the dehydration tank 6 through the ventilation port 11 provided in the outer lid 4.

  Further, in conjunction with the rotation of the dewatering tank 6, an exhaust action is generated at the outer peripheral portion of the opening 8 of the dewatering tank 6 by centrifugal force. By this exhausting action, the air in the dehydration tank 6 is exhausted from the exhaust port 10 provided in the inner lid 5 toward the outside of the machine body through the ventilation port 11 provided in the outer lid 4. The exhausted air includes moisture inside the dehydration tank 6.

  As described above, the air in the dehydration tank 6 is ventilated through the ventilation port 11 provided in the outer lid 4 and the intake port 9 and the exhaust port 10 provided in the inner lid 5 in conjunction with the rotation of the dehydration tank 6. The moisture inside the dewatering tank 6 is exhausted, drying of the clothes is promoted, and the dewatering efficiency is improved. Thereby, simple drying of clothing is also possible.

  In the present embodiment, the outer lid 4 is provided with one ventilation port 11, but a plurality of ventilation ports 11 are provided at positions corresponding to the intake port 9 and the exhaust port 10 provided in the inner lid 5. By providing the pieces, ventilation is performed more efficiently, drying of clothes is further promoted, and the dewatering efficiency is further improved.

  As described above, the two-tub washing machine according to the present invention efficiently ventilates the air in the dewatering tank and improves the dewatering efficiency, so that it can be used for other washing machines having a dewatering function and a clothes drying function. Is also applicable.
