Description

Dish Washer {DISH WASHER}

The present invention relates to a dishwasher having a function of washing water by supplying water in a storage tank into a washing tank.

Conventionally, the typical dishwasher is to branch off the water required for washing from the branch faucet, to supply water, and to wash. The configuration of this kind of dishwasher will be described with reference to FIGS. 6 and 7.

As shown in FIG. 6, the dishwasher main body 1 has the washing tank 2 installed inside, and was attached to the tap water 3 in this washing tank 2 as shown in FIG. The water is branched from the branch faucet 4, and the water or hot water is supplied by opening and closing the water supply valve 5. The water supply hose 6 is connected from the branch faucet 4 to the water supply valve 5. A drain port 7 is provided at the bottom of the washing tank 2, and in conjunction with the drain port 7, a washing pump 9 driven by a motor 8 is mounted. Thus, the washing water is configured to circulate into the washing tank 2. The operation of the electric components such as the motor 8 and the water supply valve 5 is controlled by the control device 10. Moreover, the drain port 7 is equipped with the remnant filter 11 which collects remnants.

In addition, a heater 13 for washing water heating is provided between the cleaning nozzle 12 and the bottom of the cleaning tank 2, and the object to be cleaned 14 is arranged above the cleaning nozzle 12. The dish basket 15 configured to spray the washing water effectively onto the object to be cleaned 14 is provided, and the washing is efficiently performed. At the same time, a part of the washing water from the washing nozzle 12 also comes in contact with the washing tank 2, and the washing tank 2 is also washed. In addition, the drain pump 16 discharges the washing water to the outside of the washing machine through the drain hose 17 (see, for example, Japanese Patent Laid-Open No. 2003-210378).

However, in such a conventional structure, since the branch faucet 4 is provided in the tap water faucet 3, and the water supply hose 6 is connected to the branch faucet 4, the water is supplied into the washing tank 2. Since the branch faucet 4 is normally used always in an open state, tap water pressure is directly applied, a pressure resistant structure is required, and the structure of the branch faucet 4 is very complicated. Moreover, suitable branch faucets 4 are required for each tap water faucet 3, and various kinds are needed, and installation work by an expert is also required, and it becomes increasingly difficult to use a dishwasher.

There is also a use method in which the water supply hose 6 is directly connected to the faucet 3 without using the branch faucet 4, but in this case, it is inconvenient that the faucet 3 cannot be used differently when the dishwasher is used. There was a ham. In addition, if the water faucet 3 was closed, the connection of the water supply hose 6 was lost, or the water supply hose 6 bursted by water pressure, causing water leakage.

In addition, control of the water supply amount is performed by opening and closing the water supply valve 5, and since the water supply water pressure is directly applied to the water supply valve 5 at the time of opening of the branch faucet 4, the internal pressure structure was required similarly.

As a method of suppressing water pressure, a means of using a storage tank is also considered. However, in a configuration of only a storage tank without a drainage function, when the water stored in the storage tank is left unused for a long time, bacteria are stored in the storage tank. It breeds, and water decays, it causes a bad smell, and it is thought that it causes the phenomenon which is also unhealthy. In the configuration of the storage tank only without the drainage function, the means for draining the water remaining in the storage tank needs to perform a normal cleaning operation.

The present invention solves the above-mentioned problems, and by using the water storage tank and the drainage means, the problem of water remaining in the absence of the drainage means is solved, and a branched faucet with a complicated structure is not required. We do not need installation construction by the way and aim at greatly improving installation characteristics, safety, usability.

In order to achieve the above object, the present invention, in order to achieve the above object, the water to be supplied to the cleaning tank for cleaning the object to be cleaned, such as tableware is stored in the reservoir tank, the water is supplied by the water supply means in the cleaning tank, and the water in the cleaning tank is drained. The water in the reservoir tank is supplied to the washing tank by the water supply means, and the water supplied to the washing tank is drained by the drain means.

Thus, by using the reservoir tank and its drainage means, it is possible to solve the problem of the remaining water generated in the absence of the drainage means, and does not require complicated branch faucets, and does not require installation work by experts. Installation, safety and ease of use can be greatly improved.
