FIG. 13 is a cross-sectional view taken along line B-B of FIG. 11.

5 to 13, the base 100 extends along the circumference of the base 100 and is located in front of the inner region surrounded by the circumferential reservoir part I and the circumferential reservoir part I in which scattered water is stored. Washing is formed in the rear of the front reservoir (II), the inner region surrounded by the circumferential reservoir (I) to store the wash water scattered forward of the base 100, and scattered to the rear of the base 100 A back reservoir (III) for storing water.

The circumferential reservoir I is scattered to the outside of the washing tank 10 during the operation of the washing machine 1 to store the washing water flowing along the inner wall of the cabinet 2. The circumferential reservoir I is formed with a flow path for storing wash water, and the flow path is formed by ribs 121 and 122 extending along the circumference of the base 100, which forms both sides of the circumferential reservoir I. Can be formed. A partition wall 123 may be formed between the first rib 121 and the second rib 122.

The circumferential reservoir I is formed with a fastening portion 124 to which a fastening member such as a bolt is fastened to fasten the base 100 and the cabinet 2, and the fastening portion 124 of the circumferential reservoir I is formed. A boss structure protrudes from the bottom surface.

A flow path 135 is provided between the fastening portion 124 and the first rib 121 so that a fastening member such as a bolt fastened to the fastening portion 124 does not come into contact with the wash water stored in the circumferential water storage portion I and corrode. Is formed. The first face 126 on which the fastening part 124 is formed is formed higher than the second face 127 of the other part of the circumferential reservoir I and from the first face 126 on which the fastening part 124 is formed. The inclined surface 128 is formed to be inclined downward toward the second surface 127 of the other portion. The flow path 135 extends along the inclined surface 27. Therefore, since the wash water scattered to the first surface 126 on which the fastening part 124 is formed is guided downward along the flow path 125, the fastening member is reliably prevented from being corroded by the wash water.

The partition 123 is provided with a plurality along the circumferential reservoir I, and scattered water accumulates in the respective storage spaces formed between the plurality of partitions 123. At this time, between the partition wall 123 is formed with a drain pipe 129 for draining the wash water of a predetermined level or more in the peripheral reservoir (I).

On the other hand, since the circumferential storage part I is formed by the space enclosed by the 1st rib 121 and the 2nd rib 122, the scattered water collected by the circumferential storage part I is the circumferential storage part I. The height starting to overflow is determined by the lower of the height of the first rib 121 and the second rib 122. Hereinafter, the height of the 1st rib 121 and the 2nd rib 122 is demonstrated to be the same. In addition, the heights of the partition walls 123 in which the plurality is formed along the circumferential reservoir I are described as being the same, but are not limited thereto.

The drain pipe 129 extends vertically from the second surface 127, and the height of the drain pipe 129 is lower than the height of the first rib 121 and the second rib 122, and is higher than the height of the partition wall 123. It is formed high.

Therefore, when the water level of the storage space 161 formed between the partition walls 123 gradually rises and exceeds the height of the partition walls 123, the water is not drained directly through the drain pipe 129, but is beyond the partition walls 123. The adjacent reservoir space 162 is filled. Therefore, since the drainage is not made through the drain pipe 129 until all of the plurality of storage spaces 161, 162, 163 formed by the plurality of partitions 123 are filled, the amount of scattering water that the peripheral reservoir I can store. This has an increasing effect.

Referring to FIG. 13, the first reservoir space 161, the second reservoir space 162, and the third reservoir space separated by the partition walls 123 are included in the peripheral reservoir I. 163 is formed. At this time, if the scattered water flows along the first surface 126 to the second surface 127, the height of the drain pipe 129 formed in each of the storage spaces 161, 162, and 163 is greater than the height of the partition wall 123. As high as h, the scattered water first fills the first reservoir space 161 and when the water level increases gradually, the adjacent second reservoir space 162 and the third drain space 163 are not drained through the drain pipe 129. Will be filled in order. Therefore, the water is not drained through the drain pipe 129 until the water level of all the storage spaces 161, 162, 163 is higher than the height of the first rib 121.

The front reservoir II is formed at the front of the inner side of the base 100 surrounded by the peripheral reservoir I and is scattered to the inside of the front side of the washing water or cabinet 2 flowing down the outer tub 4 and bounced off. Drain the washed wash. The front reservoir II may be formed with a grid-shaped reinforcement rib 131 for reinforcing the rigidity of the base 100, and scattered water may be stored in a space partitioned by the reinforcement rib 131 in a grid-shaped space.

The rear reservoir III is formed at the rear of the inner side of the base 100 surrounded by the circumferential reservoir I and is scattered to the inside of the rear side of the wash water or cabinet 2 flowing down the outer tub 4 and bounced off. Drain the washed wash. The rear reservoir III includes a pump mounting unit 142 on which the pump 24 is mounted, and a sensor mounting unit 150 on which the scattering water detecting sensor 80 is mounted.

The rear reservoir III washes the wash water in a space formed by the second rib 122 of the circumferential reservoir I and the rib 125 formed along the circumference of the opened portion IV in the center of the base 100. Reservoir

The rear reservoir III includes a catching inclined surface 143 formed to be inclined downward toward the sensor mount 150 to guide the wash water collected in the rear reservoir III to the sensor mount 150.

On the catch slope 143, ribs 144 extending along the slope direction of the catch slope 143 are formed to restrict the washing water guided along the catch slope 143 from flowing laterally.

The sensor mounting unit 150 includes a bracket 151 to which the scattering water detecting sensor 80 is fastened, and a catching unit 152 forming a groove to collect the wash water guided along the catching slope 143. The water collecting unit 152 is formed by being recessed from the surface 155 through which the washing water guided along the water collecting slope 143 passes. A rib 154 is formed along the edge of the face 155.

On the other hand, the sensor mounting portion 150 is provided with an outlet portion 153 for discharging the excess downstream when the amount of wash water is collected more than the capacity of the water collecting portion 152. The outlet 153 may be implemented by allowing a gap to be formed between the scattered water detecting sensor 80 and the rib 154 when the scattered water detecting sensor 80 is mounted to the sensor mounting unit 150.

By draining the wash water overflowed from the water collecting unit 152 by the outlet 153, the positive electrodes 82a and 82b of the scattering water sensor 80 may be prevented from being immersed and corroded for a long time.

The washing water flowing out through the outlet 153 does not leak to the bottom IV on which the washing machine 1 is mounted by the ribs 125, but is stored in the rear reservoir III to naturally evaporate.

The positive electrodes 82a and 82b of the scattering water detecting sensor 80 are horizontally spaced apart from the bottom of the catchment unit 152 at a horizontal interval, and the water level of the wash water gathered in the catchment unit 152. When the two electrodes 82a and 82b are immersed in the wash water at a predetermined level or more, electric signals detected by the electrodes 82a and 82b are detected to detect whether the wash water is scattered.

The first terminal 83a and the second terminal 83b are electrically connected to the control unit 27 to transfer an electrical signal detected between the first electrode 82a and the second electrode 82b to the control unit 27 side. do. The control unit 27 detects the wash water according to the electric signal transmitted from the scattered water detection sensor 80 and through this, by decelerating and controlling the rotation speed of the inner tank 6, it is possible to prevent further wash water from scattering. have.
