Further, the water suction pipe and the pump are connected to each other, and are supported by the support portion 2 and arranged at the upper open portion of the water tank S. In this embodiment, the support part 2 is installed on the edge of the water tank S and supports the main body of the washing machine. With this arrangement, the dishwasher main body becomes a lid that covers a part of the water tank.

Alternatively, as shown in FIGS. 2a and 2b,
It is also possible to configure the dishwasher as a lid that covers the entire water tank, with the edge of the washer body 1 serving as a support portion.
In the case where the dishwasher is configured to serve as the entire lid of the water tank, a through hole 6 for passing water supplied from the faucet B into the water tank is provided. 3a and 3b
As shown in (1), the support 2 may be formed as a leg extending from the bottom of the water tank S to the dishwasher main body 1.

The washing machine main body 1 and the support portion 2 are formed as lids for partially or entirely covering the water tank shown in FIG. 1 to FIG. It is possible to prevent the scattered water from flying outside the water tank.

The water tank S may be any water tank having a drain port D that can be opened and closed, and a sink in a general household kitchen can be used as the water tank S. However, it is also possible to use an independent aquarium having a washing tub shape, and this can be used in a kitchen sink. Drainage of water from the water tank is performed using an openable drain port D. The drain port is opened and closed by the operation of a handle provided near the faucet B, and the drain port is fitted to the drain port at the bottom of the water tank S to discharge. A commonly known openable and closable drain port such as a drain port having a rubber stopper for sealing the container can be used.

However, when the kitchen sink is used as a water tank as described above, it is preferable to store the tableware A in the tableware storage basket 8 as shown in FIGS. FIG.
FIG. 3 is a perspective view showing an example of a tableware storage basket. As shown in FIG. 4, as the tableware storage basket 8, various baskets capable of allowing water to pass therethrough with an open upper portion can be used. It is preferable to provide a partition 8a that can arrange tableware at intervals so that A can be easily received.

The water suction pipe 4 is provided in the water tank S by the operation of the pump P.
Is supplied to the main body 1 of the washing machine, and the length of the water-absorbing pipe is set so as to reach the bottom of the sink S from the main body 1 of the dishwashing machine. Further, a filter 12 for filtering water to be sucked up can be provided at the inlet of the water absorption pipe. This filter may be provided in a pipe connected to a washing nozzle in the washing machine body.

The pump P serves as a drive source for sucking up the water stored in the sink S and jetting water from the washing nozzle. The operation of the pump P is generated by the operation of the control unit 3 provided in the dishwasher main body 1. Is controlled by a given signal.

The cleaning nozzle 5 is connected to the water absorbing pipe 4 by the pump P.
Spouts the water sucked up through. The ejection direction of the washing nozzle can be fixed as shown in FIG. 1 to FIG. 3 to the tableware A, or can be of the rotating type shown in FIG. 5a and FIG. 5b. .

The operation panel 11 may be provided with a lamp for displaying the current operation process such as “water rinse”, “detergent wash”, and “hot water rinse” as described in detail later.

The steps of the simple dishwasher according to the present invention are described below. The drain port D is closed, and hot water is supplied to the water tank S from the faucet B. At this time, the hot water supply temperature is preferably as high as about 40 ° C. to 60 ° C. The amount of hot water supplied may be such that the level of the hot water reaches the lower end of the water absorption pipe 4 and the hot water can be absorbed by the pump P (hot water supply process). The switch on the operation panel 11 is turned on, the pump P is operated, the water stored in the water tank S is absorbed through the water absorption pipe 4, water is spouted from the washing nozzle 5, and the tableware stored in the storage basket 8. Wash class A. At this time, by supplying a necessary amount of detergent in the water tank in advance, the supplied water dissolves the detergent and becomes a cleaning liquid. The water sprayed on the tableware A flows down and is sucked up again by the water suction pipe 4,
It circulates so as to be ejected from the cleaning nozzle 5. When an appropriate time elapses from the start of the operation of the pump P, the control unit 3 sends an end signal to stop the pump P. It is preferable to notify the completion of the cleaning by an alarm or the like at the same time as the completion of the cleaning (detergent cleaning step). After the washing is completed, the drain port D is opened to discharge water (drain process). The drain port D is closed, and water is absorbed into the water tank S from the faucet B.
