Abstract

PROBLEM TO BE SOLVED: To make the acceptable criteria of residual water quantity clearly recognize, by marking a guidepost line higher than a standard water level after draining soiled water after washing or rinsing onto a side wall of a water reservoir part. SOLUTION: Soiled water cannot be completely drained when a comparatively inexpensive volute pump is used because air is rolled into drained soiled water. Consequently residual water is remained in a water reservoir part 13 under a washing tub after the completion of draining motion. The residual water becomes visible for a user by detaching a residue filter. A water level guidepost line A is marked higher than the normal water level after soiled water draining after washing or rinsing onto a side wall 13a of the water reservoir part 13. When the water level is lower than the guidepost line A, it shows that the dish washer is normally working even if there is residual water. When the water level is higher than the guidepost line A, maintenance is to be carried out. Thus the residual water quantity of the dish washer can be easily judged.

で、そのような事態が顕著に現れる。However, dishwashers often use relatively inexpensive vortex pumps as drainage pumps. Sewage cannot be discharged, and the residual water remains in the reservoir below the washing tank after the drainage operation.
The basin filter is usually invisible to the user due to the garbage filter, but if the user removes the garbage filter when cleaning the inside of the washing tank, the residual water remaining in the basin can be seen. Would. Then, if the user feels that the residual water amount is large, it is suspected that the pump is poorly drained or that the rinsing is insufficient, and it seems as if the product is defective. In particular, a thin dishwasher that requires a small installation space in accordance with the kitchen situation in Japan has to make the ponds narrow and the remaining water volume becomes relatively high. Appears remarkably.

After the end of the drainage operation, the amount of residual water in the cleaning tank will increase more than usual. However, if there is no standard for quantitatively grasping the normal state and the abnormal state of the residual water, the user will not know whether it is abnormal or not, and may continue to use it in the abnormal state and lead to the failure of the dishwasher. is there.

Hot water stored in the washing tank by a predetermined amount using the water supply means 10 is circulated in the dishwasher 1 by the operation of the pump 11. (Water reservoir 13 → pump 11 → injection from washing nozzles 8 and 9 → applied to dishes → water reservoir 13) Thereby, washing of the dishes and rinsing a plurality of times are performed. After each operation of washing and rinsing, a drain operation is performed, and the water stored in the washing tank 3 is pumped by the pump 11.
Is discharged out of the tank. Then, new hot water is supplied for the next step.

を行うことができる。However, since the water level reference line A is provided on the side wall 13a of the reservoir 13 above the normal water level after draining the sewage after washing or rinsing, the water level after the water level reference line A is drained. Is low, the user can know that the dishwasher 1 is operating normally even if there is residual water. On the other hand, if the water level after draining is higher than the water level reference line A, it is known that an abnormality has occurred somewhere in the dishwasher 1, so that maintenance of the dishwasher 1 should be performed before a major failure occurs. Can be.

きる。In the dishwasher 1, by providing a water level reference line A indicating an appropriate value of the residual water amount in the reservoir section 13, the user can easily determine whether the residual water amount after draining is normal or abnormal. Become. Therefore, there is no doubt that the normally operating dishwasher 1 is defective, and the dishwasher 1 with abnormal drainage can detect the abnormality at an early stage and perform maintenance before leading to a major failure. it can.
