Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in dishwashers (hereinafter referred to as "dishwashers").

In conventional showers and jet-type dishwashers, the jet from the spray nozzle that rotates as a reaction to the jetting force of the washing liquid hits the dishes stored in the basket inside the dishwasher, directly hitting the surface of the dishes. Wash away stubborn dirt.

Some of the jets directly hit the inner wall of the dishwasher in addition to the dishes, causing the inner wall of the dishwasher to vibrate, becoming the main source of noise while the dishwasher is operating, and causing discomfort to the dishwasher user. was there.

In order to solve these problems, we have developed a structure in which the hot water supply hole 3 in which the interior and exterior of the dishwasher in FIG. Measures were taken to reduce the amount of water and noise.

In particular, in the latter case, it was not a desirable measure because it had a large effect on the cleaning effect of tableware.

The present invention has been made to improve the above-mentioned drawbacks, and can be easily implemented without changing the characteristics of the water pump 15 shown in FIG. 2.

That is, according to the present invention, in addition to the dishes, the jets that directly hit the inner wall of the dishwasher are dispersed and dissipated by using the cotton fabrics 6, 7, and 8 provided around the sides of the washing box and on the side lid of the dishwasher.
The purpose of this invention is to provide a low-noise dishwasher that absorbs the energy directly hitting the inner wall 11 and dampens the vibration of the inner wall.

According to the present invention, a fine mesh screen is provided around the side surface of the washing box of the dishwasher and on the side lid of the dishwasher, and the mesh prevents the jet of cleaning liquid from directly hitting the inner wall of the dishwasher.

Embodiments of the present invention will be described in detail below with reference to the drawings.

That is, FIG. 1 is a perspective view showing one embodiment of the dishwasher according to the present invention, with the washing basket and the lid side pulled out;
This figure is a schematic view showing the interior of the dishwasher according to FIG. 1 during the washing of dishes.

An inner wall 11 is provided within the outer frame 1 that encloses the dishwasher W, and the front opening of this inner wall has a door 16 that closes it, and there is a water pump driven by a motor inside to circulate the cleaning liquid. 15, a spray nozzle 14 that sprays the cleaning liquid from the pump 15 and plays the role of washing dishes, washing baskets 7 and 8, a clay side lid 6, and a shower 12 for rinsing dishes are arranged, respectively.

As shown in FIGS. 3 and 4, nets 5 are removably attached to the frames 10 of the wash baskets 7 and 8, respectively, by fixing hooks 9 around the sides of the clay brush 7 and the countermeasure 8.

The clay pen 7 can be easily stored in the dishwasher by means of wheels 17 and 18.

As shown in the figure, a part of the side surface of the lower box has a notch 5a through which the spray nozzle tower 17 passes when the basket is put in and out of the dishwasher. Easy to store.

FIG. 5 shows a lid 6 used for a clay pen 7. The lid 6 is removably attached to a part of the upper box frame by a hook 19 provided on a part of its side surface, and the upper and lower baskets 7 and 8 are connected to each other. A hole 4 is provided at a position facing a rinsing shower 12 provided on the ceiling of an inner wall 11 of the dishwasher when the dishwasher is housed in the dishwasher.

The hook 9 for fixing the cotton material 5 provided around the side surface has a dish part 9a and a claw part 9b integrally constructed as shown in FIG.
, are fixed to the frames 10 of each of the baskets 7 and 8 through holes 20 (see FIG. 7) provided in the cotton 5 so that the claws of the fixing hooks 9 are sandwiched therebetween.

Further, when the cotton material 5 is to be removed, it is done by removing the fixing hooks 9 from each frame.

FIG. 7 shows the cotton 5 attached around the sides of each of the washing baskets 7, 8.

As shown in the figure, holes 20 are provided in the cotton material 5 at positions facing a part of the frame 10 of each of the washing baskets 7 and 8.

Through the holes 20, the net 5 is attached to the washing basket 7.8 via fixing hooks 9.

The above-described clay brush and lower box according to the present invention can be easily installed even in a dishwasher installed in a general household.

Furthermore, the washing effect of the dishwasher itself can be improved by increasing the water pressure and water volume of the water pump to a slightly higher level than the current performance, without reducing the dishwashing effect of the dishwasher itself.

In addition, you can store dishes in the washing basket as before, and the usability remains the same.

Furthermore, since a fine-mesh screen is used, dirt adhering to tableware will not stick to the cotton and will be washed like tableware by the jet stream. By removing the hook, cotton can also be removed and washed with a scrubbing brush.

Next, the noise attenuation effect of the dishwasher according to the present invention will be explained using measurement data.

In carrying out the present invention, it is assumed that the cotton provided in the upper and lower baskets and the lid is made of a corrosion-resistant material, such as stainless steel or plastic material, and the number of meshes of the cotton is 30 to 5.
The experiment was conducted assuming that the mesh was approximately 0 mesh.

Cotton with a mesh size of 20 mesh or less is not preferable in terms of noise control, as it is difficult to absorb soiled objects that adhere to dishes, and it is difficult to disperse and absorb the energy of showers and jets.

The table compares the noise data of a conventional dishwasher and a dishwasher according to the present invention, which were measured using an ordinary sound level meter installed at a microphone height of 50cm and 1m apart in front of the dishwasher. be.

As is clear from the table, the present invention has an improvement of 10% compared to the conventional example.
A decrease in dB is observed.

In the above embodiment, cotton was attached to the upper and lower baskets and the lid of the dishwasher, but the invention is not limited to this. A similar effect can be obtained by providing cotton all over the inside of the washing machine.

Furthermore, it goes without saying that the mesh is not limited to the above example, and various modifications can be made depending on the size of the pump.
