Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to improving the performance of a dishwasher, and particularly to a dishwasher that is effective in reducing noise.

[Prior art]

In a dishwasher, as shown in Figs. 1 to 3, the washing water A' jetted from the washing arm nozzle 3' must have sufficient jetting pressure to remove dirt from the items to be washed 6'. . Conventionally, the washing tank 1' of a dishwasher and the door 2' that covers it and forms the washing chamber are made of a pressed metal plate or a molded synthetic resin, and the washing arm nozzle 3' and the door 2' are made of a pressed metal plate or a molded synthetic resin. The cleaning water A' has a high jetting pressure and a large flow rate, and hits the cleaning tank 1' or the door 2', causing a large noise like being hit by a kite.

[Purpose of the invention]

The present invention aims to provide a quiet dishwasher that reduces noise, which has been a major problem when operating a dishwasher.

[Summary of the invention]

The present invention focuses on the fact that the high-pressure jetted cleaning water spouted from the cleaning arm nozzle vibrates the cleaning tank and the door forming the inside of the cleaning chamber, thereby generating large noise. One is that the cleaning tank and the door are almost flat, so the jet of cleaning water hits the surface. Moreover, it had a fairly large area and was configured to easily generate vibrations due to contact with the jetted cleaning water. Secondly, because the amount of water jetted out from the cleaning arm nozzle was high in the direction of the jet row, it caused a strong impact when it hit the cleaning tank and the door. It has been found.

In addition, by increasing the rigidity of the bottom of the cleaning tank and the door to prevent vibration, when the jetted cleaning water hits the cleaning tank and the door, the impact force is dispersed, thereby reducing noise. We considered that the surface or back surface of the cleaning tank and door that is in contact with the jetted cleaning water, or both sides, should be made into an uneven shape to increase rigidity, and the surface that is in contact with the jetted cleaning water should be shaped like ribs, pins, bosses, etc. By doing so, the main point is to disperse and reduce the impact force on the cleaning tank and the door surface by dispersing the flow rate of the jetted cleaning water even if it hits the cleaning tank.

Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 4 to 6.

A pump 4 is attached to the bottom of the cleaning tank 1 for pressurizing cleaning water and jetting it through the cleaning arm nozzle 3. The opening of the cleaning tank 1 is grooved so as to form a cleaning chamber by opening and closing the opening with a door 2 when in use, and the cleaning operation of the objects 6 placed in the cleaning chamber is carried out via the storage basket 5. Reference numeral 8 denotes a panel in which the electric control parts 7 are incorporated, and together with the door top plate 20, forms the appearance of the front of the dishwasher. Further, the cleaning tank 1 and the door 2 are provided with a tank lip 11 and a door lip 21 facing the cleaning chamber formed by them.

The operation of the dishwasher of the present invention constructed as described above will be explained. When cleaning water is supplied into the cleaning chamber, the electric control component 7 starts operating the pump 4. The pump 4 pressurizes the washing water and jets it out at a high pressure from the washing arm nozzle 3.

This jetted cleaning water A cleans the objects 6 placed in the storage basket 5, but at this time, the jetted cleaning water A not only hits the objects 6 that do not hit them but also passes through them. However, even if the water reaches the surface of the cleaning tank 1 and the door 2 with a considerably high jet pressure, the cleaning tank 1,
Each of the doors 2 has rigidity due to the tank ribs 11 and door ribs 21, and vibrations generated by the impact of the jetted cleaning water A can be suppressed to a minimum. Furthermore, since the jetted cleaning water A itself hits the tank lip 11 and the door lip 21, the jetted flow rate is dispersed and the resulting impact force is dispersed and alleviated, so that vibrations are not generated in the cleaning tank 1 and door 2. There is. This allows the generation of noise to be kept to a minimum.

Further, as shown in FIG. 7, tank ribs 11 are provided on the back surfaces of the cleaning tank 1 and the door 2 facing into the cleaning chamber. Providing the door rib 21 is effective, but it only increases the rigidity of the cleaning tank 1 and the door 2 and minimizes the occurrence of vibration, and the jetted cleaning water A
cannot contribute to the dispersion of the impact force. However, it can be said to be effective when conditions are given to the design, such as when it is necessary to ensure the effective capacity of the cleaning chamber.

It is needless to say that the most effective one is one in which tank ribs 11 and door ribs 21 are provided on both the front and back sides of the cleaning tank 1 and door 2.

〔Effect of the invention〕

As described above, the present invention has a simple structure and is very effective in reducing noise, which has been a major problem in millet washing machines.
