の排水ポンプである。Conventional Structure and Problems Conventionally, dishwashers are well known that use a pressurized water supply device such as a pump to spray washing water from a nozzle onto objects to be washed in a washing tank. A schematic diagram thereof is shown in FIG. 1st
In the figure, reference numeral 1 denotes a cleaning tank that accommodates a plurality of storage baskets 3 in which items to be cleaned 2 are placed and performs cleaning, and upper and lower nozzles are rotated by hydraulic power sent by a pressurized water supply device such as a pump 4. A cleaning liquid is sprayed from small holes provided in the bodies 5 and 6 to clean the object 2 to be cleaned. The cleaning liquid 7 used for this cleaning is temporarily stored at the bottom of the cleaning tank 1, and while being heated by the heater 8, it is passed through the leftover filler 9 to the pump suction path 10, the pump 4, and the -2T lower nozzle body. It circulates through the pump discharge paths 11 and 12 to the pumps 5 and 6, and the normal path inside the cleaning tank 1. 13 is a water supply valve for supplying new water, and 14 is a drain pump for draining the dirty cleaning water after washing.

らないというわずられしさがあった。In such a dishwasher, for example, a gate valve such as a solenoid valve is provided on either side of the pump discharge path 11 or 12, and the upper and lower nozzle bodies 6, In some cases, the cleaning solution 7 is sprayed only on one of the storage baskets 6, and only one of the storage baskets 3 is used when the amount of items to be cleaned is small. or,
For example, when the storage basket 3 on the north stage is removed from the cleaning tank 1, a mechanism that blocks the discharge path 11 leading to the nozzle body 6 on the upper stage causes cleaning liquid to be sprayed from only the lower nozzle body 6 to the storage basket 3 on the lower stage. A device designed to wash tableware 2 in step 3 is also being considered. However, the problem with such conventional dishwashers is that even if there is only a small amount of 111 in the object 2 to be washed, the washing is performed with the same capacity as when washing the entire object, so the amount of water, heat, etc.
Please use more power than necessary considering the amount of electricity, etc.
There are many. Also, devices such as pumps Kt are operated at the same output as when cleaning a large amount of items, so they produce more force than necessary. I was using ik energy. What's more, not only are there a small number of items to be cleaned, but what's more, if there are few stains on the dishes, how about the conventional method? )ζ
In this case, since the pump discharge path is only narrowed, the discharge pressure is strong, and the energy used is far greater than the jetting force of the washing dI liquid necessary for cleaning the dirt, resulting in an even more wasted state. Furthermore, in the past, all the settings for the facial cleansing program for a small wash were done in one step.
The user has to judge and set the number of Susuki cycles, etc., one by one, which is cumbersome.

的な７５１Ｌ　汀ｌが可能である。To explain the operation in the above drawing, first, the storage basket 2
2, the items to be washed (tableware) 21 are placed in a washing tank 20. At this time, the storage baskets 22 and 22 are subjected to weight sensors 36 and 37 to detect their respective weights, and the signals thereof are sent to the control device 41. If the contents of the signal, for example, a signal that the tableware has less Jil and is lighter in weight, the water level sensor 35 is controlled according to the degree so as not to drain the water supply 111, and the rotation speed of the motor 23 is further reduced. A signal is sent to the rotation control device 40 to cause the flow to flow, and the overflow J11 regulating valve 38.39 provided in the a0 liquid discharge path 31.32 is throttled to shut down the nozzle bodies 25, 26.
t, let it come out, wash i'rt reduce the flow rate of moths, and further,
Cleansing, throbbing and drying in the body program: q
control to shorten the time. If the number of small dishes (71) is large and heavy, the water supply will be increased accordingly.
1 and further increase the rotation speed of the motor 23, the flow J(
The opening degrees of the Y adjustment valves 38 and 39 are increased, and the washing time M+, Suzuki, and drying times in the overall program are further increased. For example, if the amount of dishes in the first storage basket 220 is large and the amount of dishes in the lower storage basket 220 is small, only the flow rate adjustment valve 39 of the cleaning liquid discharge path 32 that supplies the cleaning liquid 27 to the lower nozzle body 26 should be turned on. The cleaning liquid is spouted in a smaller quantity than the upper nozzle body 25, and the water supply amount pump rotational speed is changed accordingly. With this kind of operation, when the amount of dishes is small, the amount of dishes is detected by weight, the amount of cleaning liquid ejected from the nozzle body is reduced, and the total program time is also shortened, allowing cleaning according to the small number of dishes. This allows for efficient cleaning without using unnecessary cleaning fluid. Furthermore, waste of pump power caused by restricting the flow rate is eliminated by lowering the rotational speed of the motor, resulting in energy savings. Furthermore, ``Ichidan,''
Since it is possible to change the jet flow 11 from each of the lower dishes according to the f1'l of the lower tableware, a very efficient 751L basin is possible.

とが出来るものである。Effects of the Invention As is clear from the above embodiments, the dishwashing machine of the present invention detects the amount of tableware with a weight sensor, and adjusts the water supply amount, pressurized water supply capacity, and overall program time according to the detected amount. Since it is possible to set at least one of the following, when there are few nails on the dishes, it is not necessary to wash the dishes with more Ronu than necessary, and it is possible to wash the dishes efficiently. In addition, in the case of a container with a lower storage container, due to the difference in the amount of tableware, ``2. Downward jet flow ii1. 2. Partial cleaning of the lower tier is also possible. If you have a configuration that changes the flow rate J1 at the same time as the pressurized water supply capacity, you can use a large amount of power to reduce the flow rate.
It is possible to eliminate wasted energy such as washing 1 meal 81'÷.
