First, it is assumed that the tableware is stored in the tableware basket 2 and is attached to a predetermined position of the washing tank 1 and a switch (not shown) is turned on. When the switch is turned on and the operation is started, the control device 12 first executes a water supply process of supplying a predetermined amount of cleaning water to the cleaning tank 1. At this time, the water level detection means 13 effectively operates and a predetermined amount of water is poured into the cleaning tank 1. Then, the control device 1 receives the water supply end signal from the water level detection means 13.
2 receives and finishes the water supply process. Then, the washing pump 3
A main washing step is performed in which the washing water pressurized by is jetted together with the detergent from the jet port 6 provided in the washing nozzle 5. After the main washing process for a predetermined period of time, the washing water containing dirt that has been washed off from the dishes and the like then passes through the drainage route 10 and is discharged to the outside of the machine.

十分仕様を満足する。The operation of the drainage pump 8 in the drainage process will be described in detail. When the normal drainage process is completed, the water level detection means 13 again detects the cleaning water level in the cleaning tank 1.
When the residual water level detected at this time comes between the residual water level at the normal end and the lower surface of the residual food filter 7, the control device 12 controls the capacity of the drainage pump 8 to be 1.5 times the capacity during normal operation. Then, the drainage operation is performed for a certain time again. Here, regarding the improvement of the drainage capacity of the drainage pump 8, since the DC brushless motor 9 is used as the motor for the drainage pump 8, the motor rotation speed can be easily increased, and as a result, the drainage capacity is increased. Can be improved. Furthermore, the durability also fully satisfies the specifications.

きる。By the above-mentioned operation, for example, residual foods are excessively accumulated on the residual food filter 7 and the supply of washing water to the drainage pump 8 is reduced, or foreign substances adhere to the inner wall of the drainage passage 10 due to aging. The drainage path 10 is narrowed, the drainage hose 11 outside the machine is connected for a long time, the drainage hose 11 is set up at a high place and installed, or it is installed in a looped state. Even if the drainage capacity of the washing machine is lowered, the drainage failure does not occur because the sufficient drainage capacity can be obtained according to the configuration of the present invention. Therefore, stable rinsing performance can always be obtained, and as a result, high cleaning performance can be obtained without reattachment of residual foods on dish and detergent residue.

It can be easily imagined that the same effect can be obtained in the configuration. Further, the amount of increase in drainage capacity may be set to 1.3 to 1.8 times in order to obtain the effect of the present invention sufficiently.

関しては給水経路内に流量検出手段を設置してもよい。Next, the operation of the second embodiment will be described in detail with reference to FIGS. The water level detection means 15 constantly detects the drainage flow rate during the normal drainage stroke and the water supply flowrate during the water supply stroke by the function of the control means, and the drainage flow rate is equal to or less than the water supply flowrate during the water supply stroke performed immediately before the drainage stroke. When it becomes, the control device 14 controls the capacity of the drainage pump 8 to be 1.5 times the capacity during normal operation and continues the drainage operation. Alternatively, if the last drainage operation is not the last of the drainage strokes that are normally performed in several steps, the same effect can be obtained by increasing the drainage capacity during the next drainage operation. Regarding this water level detection means, a method has been shown in which the control means obtains the flow rate based on the water level obtained by the water level detection means and the water level change time, but regarding the drainage flow rate detection, the flow rate detection means is installed in the drainage route. It is conceivable that a flow rate detecting means may be installed in the water supply route for the water supply flow rate.

As a result, the drainage capacity can be improved. By this operation, for example, residual foods are excessively accumulated on the residual food filter 7 and the supply of washing water to the drainage pump 8 is reduced, or foreign substances adhere to the inner wall of the drainage path 10 due to secular change and the drainage path 10 The drainage hose 11 outside the machine is long, is installed upright at a high place, or is installed in a looped state. Even if the capacity is lowered, the structure of the present invention can obtain a sufficient drainage capacity, so that the drainage failure does not occur. Therefore, stable rinsing performance can always be obtained, and as a result, high cleaning performance can be obtained without reattachment of residual foods on dish and detergent residue.

能力より高く設定される。Further, in the conventional dishwasher, a detecting device for detecting the overflow water level is provided in order to prepare for an overflow abnormality that occurs when the detector for detecting the water supply valve failure or the water supply level does not operate. At the same time, when a water overflow abnormality is detected, the drainage pump operates to control the drainage of the wash water from the wash tank to the outside of the machine. Therefore, the drainage capacity of the drainage pump is set higher than the water supply capacity.

Next, the operation of the third embodiment will be described in detail with reference to FIGS. When the water level detection means detects the residual water level or the drainage flow rate and determines that the drainage is defective in the drainage process where the suspension and drainage operations are performed several times, the drainage capacity is increased only in the initial stage and then the normal drainage capacity is reached. Operates to decrease. And only if the drainage failure condition still occurs during the next drainage operation after the suspension,
Repeat the operation to increase the drainage capacity. This is because, for example, if foreign matter accumulated in the drainage hose is removed during drainage due to the improvement of drainage pressure, the drainage hose will discharge faster than usual, and especially the drainage hose sink sink. In the case of a tabletop dishwasher installed inside, it is possible to deal with the scattering of the wash water from the drain hose to the surroundings.
