As shown in FIG. 4, the first circulation pump 53 a is constituted by a casing 42 and a circulation pump motor 47 which are integrally formed with the filter case 23. The casing 42 is formed with discharge ports 44, 45, and the like. The hose 22 is connected to a drain port (not shown).

The spout port 45 is connected to the joint 18a through the bellows tube 40. This joint 18a is provided at the inflow port 18 formed so as to face the recessed portion 2f at the bottom of the outer groove 2. The strainer box 23 is provided in the middle of the drainage path of the water from the outer tank 2 to the drainage path (not shown), and in the circulation path of the circulation pump motor 47.

In FIG. 5, the structure of the filter case 23 viewed from other angles around the periphery is shown. FIG. 6 shows the structure of the foreign object capturing section 231 in the filter case 23. Make foreign matter such as silk or cotton wool The captured foreign matter capturing portion 231 includes a plurality of protruding portions 70 from the bottom surface. The foreign matter is wound around these protrusions 70, so that the foreign matter can be efficiently captured. In addition, since the foreign matter wound around the protruding portion 70 can be removed only in the direction of the front end of the protruding portion 70, the foreign matter can be easily cleaned and the cleaning performance is improved.

FIG. 7 is a cross-sectional view taken along the line AA ′ of FIG. 5. The water flowing from the outer tank 2 passes through the screen case 23. The water passing through is drained through the drain hose 22 or is circulated by the circulating pump motor 47. At this time, since the flowing water will surely pass through the filter case 23, the system can also capture the lint coming from the outside of the rotating drum 3. In addition, in FIG. 7, water moving from the front side of the paper surface toward the deep side is circulated through the circulation hole 471.

Here, when the heights of the protrusions 70 are the same and the arrangement density of the protrusions 70 is high, as shown in the schematic diagram of FIG. 8, the lint will be concentrated at the front end of the protrusions 70 and there will be There is a possibility that the lint in the filter case 23 becomes clogged. Here, FIG. 8 (a) is a diagram for observing the foreign body capturing section 231 from above, and FIG. 8 (b) is a diagram for observing the foreign body capturing section 231 from above.

6 (a), which is a perspective view of the foreign object capturing section 231, FIG. 6 (b), which is a view of the foreign object capturing section 213 viewed from above, and BB 'cross-sectional view of FIG. 6 9 (however, the filter box 23 is also shown). In this embodiment, the outer peripheral area 711 provided with the area located outside the foreign object capturing section 231 is provided. The first protrusion of the first height 71h 71. A second protruding portion 72 having a second height 72h lower than the first height and disposed at an inner region 721 which is an area inside the foreign object capturing portion 231. As a result, the lint is piled up in a region inside the foreign object catching portion 231 where the second protruding portion 72 is arranged. A schematic diagram thereof is shown in FIG. 10. FIG. 10 (a) is a diagram for observing the foreign body capturing section 231 from above, and FIG. 10 (b) is a diagram for observing the foreign body capturing section 231 from above. In this way, the clogging of the piping can be suppressed.

In addition, the presence of the second protrusions 72 improves the capturing performance, but the second protrusions 72 may not be provided.

An enlarged view of another example of the foreign object capturing section 231 is shown in FIG. 11. Around the periphery, a reinforcing rib 80 is provided for reinforcement. The reinforcing rib 80 is provided with a slit shape for dehydration. Thereby, dehydration of the foreign material capture part 231 can be performed. Furthermore, the dehydrated shape is not a round hole, but a slit shape 81 having an opening 82 on the upper side. Therefore, when a foreign object is entangled between a plurality of slit shapes, the shape can be directed toward the The foreign matter wound around the protrusions 70 can be removed in the same direction, and the decrease in cleaning performance can be suppressed.

In addition, the first protrusion 71 includes a protrusion 71 a having a low height attached to the front end side of the foreign matter catching portion 231. Thereby, it is possible to suppress the situation of misassembly in such a way that the filter case 23 cannot be mounted in the wrong direction when the user mounts the filter case 23.

As described above, according to the present embodiment, the foreign object capturing section 231 can efficiently remove foreign objects by having a plurality of protrusions 70. For capture.

In addition, the first protrusion 71 having a first height 71h and the first height 71h disposed in the outer peripheral region 711 of the foreign object capturing section 231 and the first height 71h disposed in the inner region 721 of the foreign object capturing section 231 are provided. On the other hand, the second protruding portion 72 having a lower second height 72h can suppress clogging of the piping and ensure the capturing performance.

In addition, since the reinforcing ribs 80 for reinforcement are provided on the outer periphery, the strength of the foreign matter capturing portion 231 can be secured.

Further, since the reinforcing rib 80 is provided with a slit shape 81 having an opening 82, it is possible to suppress a decrease in the cleaning performance.

Moreover, in the first protruding portion 71, the protrusion 71a having a low height is provided on the front end side of the foreign object catching portion 231, so that it is possible to suppress misassembly.

[Example 2]

Next, the configuration of the foreign object capturing section 231 of the second embodiment is shown in FIG. 12. FIG. 12 is a diagram of the foreign object capturing section 231 viewed from above. The difference from FIG. 6 etc. is that the density of the arrangement of the protrusions 70 of the outer region 711 and the inner region 721 is different.

The density at which the first protrusions 71 are arranged in the outer region 711 is higher than the density at which the second protrusions 72 are arranged in the inner region 721. That is, the interval (the distance between each first projection 71) at which the first projections 71 are arranged in the outer region 711 Distance) is shorter than the interval (distance between each second protrusion 72) where the second protrusions 72 are arranged in the inner region 721.

According to this embodiment, clogging of the pipe can be suppressed by the second protrusions 72 having a low density, and the catchability can be improved by the first protrusions 71 having a high density.

In addition, although the arrangement form of the protrusions 70 is generally staggered as shown in FIGS. 6 and 12, the present invention is not limited to this. For example, a grid-like arrangement may be adopted.

Although the foregoing embodiment is described by taking a drum-type washer-dryer as an example, the present invention is also applicable to a vertical-type washing machine, and the drying function is not absolutely necessary. It is also applicable to washing machines that do not have a circulation pump.
