Description

  The present invention relates to a rotary vane of a washing / drying machine.

  For example, a fully automatic one-tank washing and drying machine suspends a water tank in an outer box so that it can swing freely, and a washing and dewatering tank having a rotating blade at the bottom is rotatably disposed in the water tank. Is provided with a motor, and the other end of the washing shaft, one end of which is connected to the rotor blade, is connected to the motor.

  Then, in the easy-to-wash process, the rotation of the washing shaft rotated by the motor is transmitted to the rotating blades, the rotating blades rotate, the water in the washing and dewatering tub is stirred, the water flow is generated, and the laundry is stirred. .

  By the way, there is a washing machine with improved washing performance in which a complicated water flow is generated in the tub and washing can be performed by selecting an appropriate water flow for various laundry stains (for example, see Patent Document 1). .

This is a washing machine in which a stirrer is rotatably provided at the bottom of the tank, and the stirrer is driven to rotate by a motor disposed outside the tank. An annular bottom pulsator each having a mountain and a cylindrical outer peripheral pulsator provided along the outer periphery of the bottom pulsator, and one pulsator is rotationally driven by the motor, and the other pulsator is One pulsator rotates around the same axis.
JP 2000-157775 A

  The washing machine described in JP 2000-157775 A generates a gentle water flow in one direction from the outside to the inside by rotating the outer peripheral pulsator forward or reverse or intermittently during the washing process, During the rotation stop time when the outer peripheral pulsator rotates forward / reversely or intermittently, the laundry rotates with inertial force while causing a time delay.

  Even with the bottom pulsator that rotates in this manner, a water flow different from that caused by the external pulsator is generated, and a complicated water flow is formed in the washing and dewatering tank, thereby improving the cleaning power.

  In such a washing machine that generates a complicated water flow, the laundry may be intertwined in a complicated manner by repeating the stirring operation, for example, during a process such as drying.

  Further, the motor and the washing shaft are directly connected, and therefore, it is expected that various portions are burdened by repeated use.

  The present invention provides a washing / drying machine capable of improving the washing performance and drying performance by loosening the laundry entangled during the washing process when the pulsator has a double structure, in order to solve the disadvantages of the conventional example. It is.

  The present invention according to claim 1 is a washing and drying machine in which a water tub is swingably supported in an outer box, and a washing and dewatering tub provided with a rotary blade at the bottom is rotatably arranged in the water tub. The rotary wing has a double structure in which an inner wing having a smaller diameter than the outer wing is superposed on the outer wing, the inner wing is connected to a washing shaft connected to a motor, and the outer wing is connected to the washing shaft. The ring-shaped protruding portion from the inner wing to the outer wing is formed in the scraped portion of the laundry.

  As described above, in the washing and drying machine of the present invention, clothes entangled during the washing process are easily loosened by the reciprocal movement of the outer wings by the planetary gear. In addition, the rotary wing has a double structure of the outer wing and the inner wing, so that the outer wing scrapes the clothes, and the inner wing pulls the clothes dropped by the scraping into the center of rotation of the rotary wing. Can loosen up clothing.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal side view showing an embodiment of the washing / drying machine of the present invention, FIG. 2 is a longitudinal side view of a rotary blade part which is a main part of the same, and FIG. 3 is a plan view of the same rotary blade. The configuration will be described.

  The washing and drying machine of the present invention suspends a water tank 2 in an outer box 1 through a vibration isolation mechanism so as to be swingable, and a washing and dewatering tank 3 provided with a rotary blade 7 at the bottom in the water tank 2 is rotatable. It is arranged. Further, an outer rotor type motor 8 is disposed below the water tank 2, and the other end of the washing shaft 9 having one end directly connected to the motor 8 is connected to the rotary blade 7.

  In the present invention, the rotary wing 7 has a double structure in which an inner wing 4 smaller in diameter than the outer wing 5 is superimposed on the outer wing 5, and the inner wing 4 is connected to a washing shaft 9 connected to the motor 8. The outer wing 5 was connected to the planetary gear 6 connected to the washing shaft 9. As a result, the inner wing 4 is rotated by the washing shaft 9, and the outer wing 5 is decelerated via the planetary gear 6 to be reversed.

  With such a structure, the outer peripheral portion of the outer wing 5 protrudes in a ring shape outside the inner wing 4, and this protruding portion is formed in the laundry scraping portion 5 a. A plurality (five in the illustrated example) of projections 10 are integrally projected on the upper surface of the scraping portion 5a at appropriate intervals.

  Next, the operation will be described. In order to loosen the clothes entangled during the washing process, the motor 8 rotates to rotate the washing shaft 9 directly connected thereto, and the inner wing 4 coupled thereto rotates.

  As the washing shaft 9 rotates, the outer wing 5 rotates simultaneously via the planetary gear 6. In this case, since the outer wing 5 rotates through the planetary gear 6, the outer wing 5 rotates in the opposite direction to the inner wing 4, and rotates at a speed lower than that of the inner wing 4.

  Clothing stuck to the side wall of the washing / dehydrating tub 3 is scraped off by the scraping portion 5 a by the reversal of the outer wing 5, and the scraped clothing is rotated in the washing / dehydrating tub 3 by the rotation of the inner wing 4. It is drawn in the direction of the center of rotation. As a result, the tangled clothing is loosened and the cleaning effect is increased.

  In this case, the garment is scraped off more satisfactorily by the projection 10 formed on the scraping portion 5a acting like a nail.

  In the above-described embodiment, the outer wing 5 and the inner wing 4 are configured to reciprocally move at the same time. However, the outer wing 5 is not fixed and rotated by adding a gear switching structure. You can also rotate only.

  By doing so, for example, when washing a large laundry such as a blanket, the stirring water flow obtained by the rotation of the inner wing 4 can be prevented from being reduced by the inversion of the outer wing 5, and the stirring ability is lowered. I can prevent that. And the effectiveness of using the outer rotor type | mold which can ensure a big torque for the motor 8 can also be expressed.

  In addition, when setting the washing contents at the start of washing, the weight of the clothes is detected. At this time as well, only the inner wing 4 is rotated and the outer wing 5 is stopped to prevent the weight detection accuracy from being lowered. You can also.

  Further, in the present invention, the planetary gear 6 is interposed between the washing shaft 9 directly connected to the outer rotor type motor 8 and the rotary blade 7 as described above. 8 can be reduced, and the motor 8 can be protected.

It is a vertical side view which shows embodiment of the washing-drying machine of this invention. It is a vertical side view of the rotary blade part which is the principal part which shows embodiment of the washing-drying machine of this invention. It is a top view of the rotary blade which is the principal part which shows embodiment of the washing-drying machine of this invention.
