[0006]

[Action]

 Since the present invention is configured as described above, the filter member is mounted through the opening for mounting the filter. Then, the opening is blocked. Then, for example, a pump for pumping wash water is started. Then, the wash water is pressure-fed from the wash water tank to the wash water injection nozzle through the pipe line. At this time, since the filter is attached to the pipe, the wash water is filtered without being discharged from the pipe and sprayed from the wash water injection nozzle. Therefore, the dishes are washed. After a lapse of a predetermined time or a predetermined period, remove the filter from the filter mounting portion and clean it. After cleaning, attach and use. Even if you forget to install the filter and try to clean it, the opening for mounting the filter is open, so the cleaning water is discharged outside the pipeline and cannot be cleaned.

【Example】

 Hereinafter, with reference to FIGS. 1, 2, 3, and 4, practical examples will be described in which the openings for mounting the filter are respectively implemented at the filter box, the corner portion of the pipeline, and the curved portion of the pipeline. . In the present invention, the filter mounted from the opening for mounting the filter of the pipeline can be integrated with the lid or can be implemented separately. Therefore, these are also included in the filter material. Although the same members as those of the conventional example shown in FIG. 5 are designated by the same reference numerals and the description thereof will not be repeated, according to the present embodiment, as shown in FIG. Is interposed in the conduit 9. The interposition position is at the bottom of the cleaning chamber 2 and above the cleaning water tank 3. As shown in (b) of FIG. 1, the filter box 30 is installed in the pipelines 9, 9 and has an inlet hole 35 communicating with the pipeline 9 on one side and an inlet hole 35 on the other side. Each outlet hole 36 is formed. The inlet hole 35 and the outlet hole 36 are separated by a partition wall 31 having a communication hole 34. The upstream side is a first chamber 32, the downstream side is a second chamber 33, and a cylindrical filter 44 is provided in the second chamber. It is supposed to be inserted.

An opening 37 parallel to the conduit 9 is formed below the second chamber 33 in the drawing, and a lid 40 for mounting a filter is screwed into the opening 37. . As shown in FIG. 2, the lid 40 includes a screw portion 41 that is screwed into a screw of the opening 37 of the filter box 30, a flange portion 42 that comes into contact with the side surface of the filter box 30 when attached, and a grip portion 43. It is composed of and. A tubular filter 44 is attached to the tip of the screw portion 41. The tubular filter 44 is formed, for example, by bending a net or a punching board into a tubular shape. Therefore, when the lid body 40 is screwed into the screw of the opening portion 37 of the filter box 30, the cylindrical filter 44 is inserted into the second chamber 33, and its tip end is fitted into the step portion 38 of the partition wall 31. The communication hole 34 formed in the partition wall 31 opens inside the cylindrical filter 44. On the other hand, the opening 37 of the filter box 30 is closed by the flange 42 via the seal 45.

Next, the operation of the above embodiment will be described. As shown in FIG. 1B, the lid 40 is screwed into the screw of the opening 37 of the filter box 30, and the cylindrical filter 44 is inserted and fixed in the second chamber 33. The tableware D to be washed is put in the basket W and stored in the washing chamber 2. For example, although not shown in the figure, washing time, rinsing time, etc. are appropriately set and the start button is pressed. Then, the pump 10 for pressure-feeding the wash water is activated, the wash water is filtered from the wash water tank 3 by the second filter 12, and reaches the filter box 30 through the pipe line 9. The solid matter K is filtered from the first chamber 32 of the filter box 30 through the communication hole 34 to reach the cylindrical filter 44. Then, it goes out from the second chamber 33 to the conduit 9. Then, the upper and lower wash water spray blocks 5, 6 are sprayed toward the tableware D, and the tableware D placed in the cleaning chamber 2 is cleaned. At this time, the detergent in the detergent tank 23 is also supplied to the wash water tank 3 by the ejector 22. After cleaning for a predetermined time, the pump 10 for pressure-feeding cleaning water is stopped. Then, the rinsing pump 17 is activated, and the rinsing water is pumped from the rinsing water tank 4 to the water jetting blocks 7 and 8 by the pipe 16 and jetted to the tableware D. The soot water sprayed on the tableware D is stored in the wash water tank 3 and used for the next wash. When the rinsing is finished, dry and other measures are taken to finish the washing. While the cleaning is repeated, food residues and the like will be accumulated in the cylindrical filter 44, so the lid 40 is removed from the opening 37 of the filter box 30 and the cylindrical filter 44 is cleaned appropriately.

If the user forgets to mount the tubular filter 44 and starts cleaning, the opening 37 of the filter box 30 is not closed, so that the cleaning water is discharged from the opening 37 and the cleaning water spray blocks 5 and 6 are discharged. Not reach Therefore, even if the cylindrical filter 44 is not attached, the wash water injection nozzle will not be clogged. Further, since the tableware D is not washed, solid matters such as foods attached to the tableware D do not peel off and mix with clean water. Therefore, the wash water circulates through the wash water tank 3, the pump 10, the pipe line 9 and the like, but they do not become clogged. Further, according to the present embodiment, since the filter box 30 is provided above the cleaning water tank 3 or in the cleaning chamber 2, the cleaning water discharged from the opening 37 of the filter box 30 is the cleaning water tank 3 Will be collected. Further, according to the present embodiment, since the filter 44 has a cylindrical shape, the filtration area is larger than that of a flat filter, and it is not necessary to clean it frequently. In addition, according to the present embodiment, since the pipe 16 for pumping the rinse water is not provided with the filter box 30, it is apparent that the rinse can be performed regardless of the mounting of the filter. Further, according to the present embodiment, since the rinsing water pipe 16 is not provided with the filter box 30, the rinsing can be performed even if the filter 44 is forgotten and the rinsing water cannot be cleaned. Therefore, it is safe to wash off the detergent even when it is used manually. It should be noted that even if washing is started without mounting the filter 44, the cleaning water is not sprayed from the cleaning water spraying blocks 5 and 6, so that it may be noticed that the dishes are not washed well and the filter 44 is forgotten to be mounted. it can.

In the above-described embodiment, the filter box 30 is provided in the bottom of the cleaning chamber 2 and in the conduit 9 located above the cleaning water tank 3, but the corner of the conduit 9 such as that shown in FIG. It is also possible to provide a filter at the position indicated by A or B in (a). If the filter box 30 is provided at the corner of the conduit 9, there is an advantage that the filter box 30 can be directly inserted in the conduit 9. Further, when it is provided at the A position, it has an advantage that it is easy to operate, and when it is provided at the B position, there is an advantage that the wash water leaking from the filter mounting opening is collected in the wash water tank 3. An embodiment in which a filter 44 is provided at the corner portion of the pipe 9 is shown in FIG. The same members as those in the embodiment shown in FIG. 1 are designated by the same reference numerals and will not be described repeatedly. However, according to the present embodiment, an opening 37 is formed outside the corner portion of the conduit 9, The opening 37 is threaded. Therefore, when the screw portion 41 of the lid body 40 is screwed into the screw of the opening portion 37 of the pipe line 9, the tubular filter 44 is inserted into the pipe line 9, and the tip portion thereof is the inner wall of the corner portion of the pipe line 9. 9a and the projection 9b fixed to the linear inner wall by welding, for example. It is clear that the washing water is also filtered by this filter 44.

Another embodiment of the present invention will be described with reference to FIG. According to this embodiment, a part of the conduit 9 is bent in an arc shape, and the opening 50 is formed outside the bent part. A short tube 51 having a thread is fixed to the opening 50 by welding or the like, and a lid 52 is screwed to the short tube 51. A large through hole 54 is formed in the bottom 53 of the lid 52. The filter 55 to be inserted into the conduit 9 has a substantially disc shape according to the shape of the conduit 9, and a part of the circumferential portion is fitted in the groove 56 of the inner wall of the conduit 9. A disk-shaped sealing material 57 is provided at the other end.

Therefore, as shown in FIG. 4, when the filter body 55 is mounted through the opening 50 and then the lid body 52 is screwed into the short tube 51, the through hole 54 in the bottom 53 of the lid body 52 is sealed. It is blocked by the lumber 57. Therefore, it can be washed. However, if the user forgets to mount the filter 55 and starts cleaning, the cleaning water is discharged from the opening 50 and does not reach the cleaning water injection blocks 5 and 6 as in the above-described embodiment. Even if only the lid 51 is attached, the through hole 53 of the lid 52 is not blocked by the sealing material 57, so that the cleaning water is discharged from the opening 50 through the through hole 54 of the lid 52 to the outside. According to this embodiment, since the opening 50 is formed outside the part where the pipe 9 is bent in an arc shape, the cleaning water is efficiently discharged from the pipe 9 when the opening 50 is not closed. Is released. It should be noted that it is obvious that the filter 55 can be easily mounted if the cross section of the pipe line 9 at the portion where the filter 55 is mounted is slightly modified into a square or the like.

In the illustrated embodiment described above, the filters 44 and 55 are provided only in the pipe 9 for circulating the wash water, but they can be provided in the pipe 16 for the rinse water by similar means. If the pipe 16 for the rinse water is also provided, even if a solid substance is carelessly mixed in the rinse water, the water injection blocks 7 and 8 of the rinse water are not clogged. Therefore, the pipe line also includes the pipe 16 for such rinse water.
