1 to 6, a passive washing machine 100 according to an embodiment of the present invention includes a rotation unit 110, a driving unit 120, and a body unit 130.

The rotary part 110 is formed in a cylindrical shape having an opened upper part to receive the laundry. In this case, the rotation unit 110 may be formed to be stepped in two stages. For example, the circumference of the upper side and the circumference of the lower side may be different from each other. The rotation unit 110 may be formed of a synthetic resin material.

Specifically, the rotation part 110 has a plurality of through holes 111 and a curved part 112 on a side surface thereof. The washing water flows into the rotary part 110 through the plurality of through holes 111 or flows out to the outside. The bent portions 112 may protrude in the longitudinal direction from the inner surface of the rotary portion 110 and may be arranged at predetermined intervals. The bending part 112 induces a wave to the washing water inside the rotary part 110 when the rotary part 110 rotates, thereby enhancing the cleaning force by the water.

In addition, the rotation part 110 may be formed with a receiving part 113 protruding from the bottom surface as shown in FIG. The receiving portion 113 is formed to be seated on the center projecting portion 133 of the body portion 130 to be described later. In this case, protrusions (not shown) are formed at the upper end of the central projection 133 to make point contact with the receiving portion 113, thereby minimizing the friction.

4, the rotation part 110 may have an inner engagement part 114 formed on the inner surface thereof. The inner engaging portion 114 is formed on the inner upper portion of the rotating portion 110 and is formed to be engaged with the outer engaging portion 124-1 of the pressing plate 124 of the driving portion 120 described later. In other words, the outer engaging portion 124-1 of the pressure plate 124 is caught by the inner engaging portion 114 of the rotating portion 110, and the rotating portion 110 is rotated.

The driving unit 120 rotates the handle 125 connected to the gear combination 122 and rotates the rotating unit 110 while engaging with the opened top of the rotating unit 110. In other words, the driving unit 120 allows the user to manually rotate the rotation unit 110. [ The driving unit 120 includes a lid 121, a gear combination 122, a rotating plate 123, a pressing plate 124, and a handle 125.

The lid 121 is seated on the upper part of the body part 130 and fixed to the body part 130 to close the inside of the body part 130. The lid 121 is formed of a synthetic resin material. A handle 121-1 may be formed on the upper portion of the lid 121. The handle 121-1 protrudes in a semicircular shape and can be formed to be easy to grasp by the user. A gear combination 122 is located at the center of the lid 121 and a pressure plate 124 is located below the lid 121.

The gear combination 122 is formed such that the plurality of gears mesh with each other. The gear combination 122 is arranged in the center of the lid 121. Specifically, the gear combination 122 includes a center gear 122-1, a first auxiliary gear 122-2, a second auxiliary gear 122-3, and a ring gear 122-4.

The center gear 122-1 rotates the center shaft 122-11. In this case, a pressure plate 124 is connected to one side of the central axis 122-11. In other words, as the center gear 122-1 rotates, the central shaft 122-11 connected to the center gear 122-1 rotates together, and the pressure plate 124 rotates in conjunction with the rotation.

The first auxiliary gear 122-2 rotates while engaging with one side of the center gear 122-1. The first auxiliary gear 122-2 rotates around the first auxiliary shaft 122-21. One side of the first auxiliary gear 122-2 is in contact with the center gear 122-1 and is engaged while the other side thereof is engaged with the later-described ring gear 122-4.

The second auxiliary gear 122-3 rotates while meshing with the other side of the center gear 122-1. And the second auxiliary gear 122-3 rotates about the second auxiliary shaft 122-31. One side of the first auxiliary gear 122-3 is in contact with the center gear 122-1 and is engaged while the other side thereof is engaged with the later-described ring gear 122-4.

The ring gear 122-4 is a ring-shaped gear having an inner gear teeth. The center gear 122-1, the first auxiliary gear 122-2 and the second auxiliary gear 122-3 described above are located inside the ring gear 122-4. In this case, the center gear 122-1, the first auxiliary gear 122-2, the second auxiliary gear 122-3, and the ring gear 122-4 are arranged on the horizontal plane. A plurality of engagement grooves 122-41 are formed on the ring gear 122-4. The engaging grooves 122-41 are engaged by the engaging protrusions 123-1 of the rotating plate 123. This is to allow the rotary plate 123 and the ring gear 122-4 to rotate together.

The rotating plate 123 is located on the upper side of the gear combination 122 and is connected to the ring gear 122-4 of the gear combination 122 and rotates. In this case, when the ring gear 122-4 rotates, the first auxiliary gear 122-2 and the second auxiliary gear 122-3 are rotated, so that the center gear 122-1 is rotated by the first auxiliary gear 122-1, And is rotated by the first auxiliary gear 122-2 and the second auxiliary gear 122-3. A handle 125 is connected to one side of the top of the rotating plate 123. The rotating plate 123 is rotated through the handle 125. [ A coupling protrusion 123-1 is formed at the bottom of the rotary plate 123 and the coupling protrusion 123-1 is connected to the coupling groove 122-41 of the ring gear 122-4.

The pressure plate 124 is positioned below the gear combination 122 and connected to the center shaft 122-11 of the center gear 122-1 of the gear combination 122 to rotate. The pressure plate 124 is engaged with the upper portion of the rotation unit 110 and presses them. The outer protrusion 124-1 of the pressure plate 124 is rotated while being engaged with the inner protrusion 114 of the rotary part 110. [ The pressure plate 124 may be formed in a hemispherical shape, but is not limited thereto.

The handle 125 is formed on one side of the rotating plate 123 and rotates. The handle 125 rotates as the user rotates, allowing the rotating plate 123 connected thereto to rotate in conjunction therewith. The shape of the handle 125 may be changed according to the setting of the user. Further, the handle 125 may be formed to be folded to one side of the rotary plate 123 according to the setting of the user.

As shown in FIG. 5, the center axis 122-11 of the driving unit 120 and the handle 125 may be arranged at predetermined ratios. For example, the height T from the rotating plate 123 to the handle 125 and the distance R from the center of the handle 125 to the center axis 122-11 are in a ratio of 1: 2.5 to 3 . This is to allow the user to rotate the rotary part 110 with a minimum force.

The body portion 130 is a water tank for accommodating the rotating portion therein. The protrusion 131 may be formed on the inner surface of the body part 130. The projecting portion 131 is configured to allow the washing water to form a wave height of predetermined height while the rotating portion 110 rotates. The washing water located between the body part 130 and the rotary part 110 is crushed by the protruding part 131 and a height difference is generated. The washing water that has climbed upwards moves downward, thereby enhancing the washing power while contacting laundry. In this case, the projecting portion 131 may be formed in a semicircular shape in horizontal section.

A drain port 132 may be formed at a lower side of the body part 130. The drain port 132 is opened and closed by a cap (not shown). A center protrusion 133 is formed on the bottom surface of the body part 130. The central projecting portion 133 abuts the receiving recess 113 of the rotating portion 110 and serves to hold the center of gravity when the rotating portion 110 rotates. In this case, protrusions are formed in the central projection 133 to make point contact with the receiving recess 113, thereby minimizing the friction.

Meanwhile, the passive washing apparatus 100 according to the embodiment of the present invention may further include a ceramic cylinder 140. The ceramic cylinder 140 can be seated on the upper portion of the receiving groove 113 of the rotary part 110. A ceramic material is contained in the ceramic cylinder (140). So that the rotating part 110 rotates to promote ionization of water to clean the laundry environmentally. The ceramic cylinder 140 is formed in a detachable structure with the receiving recess 113, and can be separated or combined according to the user's setting.
