Alternatively, when the drying time and the drying performance are set to be the same as before, the power consumption can be reduced by shortening the energization time of the drying heater.

(Embodiment 2) FIG. 6 shows a dish basket of a dishwasher according to a second embodiment of the present invention. Items having the same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

The difference from the structure of the first embodiment is that the uneven portion 31 is formed.
Is provided on the entire circumference of the surface material 32 in the vertical direction. The user owns a wide variety of dishes, and when setting dishes and the like in the dishwasher, they do not always set them as the manufacturer thinks. If there is, set from the opposite direction,
During actual use, such as when setting it at an angle, the specified performance must be ensured even when these settings are made. Therefore, in this embodiment, by providing the uneven portion 31 on the entire circumference of the surface material 32, it is possible to exhibit a predetermined performance wherever the tableware comes into contact.

(Third Embodiment) FIGS. 7 and 8 show a dish basket of a dishwasher according to a third embodiment of the present invention. Items having the same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

In this embodiment, when the tableware 24 such as a cup is laid down on the placing shelf 33 of the tableware basket 11, a coil-like shape is formed on the outside of a core member 34 of the placing shelf 33 having a substantially circular cross section. A surface material 35 made of a spring is provided,
The surface material 35 has an uneven portion 36 formed on the surface thereof, and the tableware 2
Point contact with 4.

Further, as shown in FIG. 8, the inner diameter of the surface material 35 made of a coil spring is 0.
By increasing the size from 1 mm to several mm, a gap 37 communicating with the uneven portion 36 is formed between the core material 34 and the surface material 35. Water droplets accumulated on the uneven portion 36 at the contact portion with the tableware 24 are removed from the tableware 24 through the surface of the surface material 35 or through the gaps between the wire rods forming the surface material 35.

Further, since the gap 37 is formed between the core member 34 and the surface member 35, more water droplets can be stored in the gap 37. Therefore, a large amount of water drops on the tableware 24.
Even when it adheres to the like, it can exert the effect of removing water droplets. In addition, the accumulated water droplets spread thinly due to the capillary phenomenon, so that they easily evaporate.

As described above, the mounting shelf 33, on which the cup or the like is laid down, has many water droplets attached due to its set state.
Due to the constitution of the surface material 35, a high water drop removing effect can be obtained.

The structure of the surface material 35 described in this embodiment and the structure in which the surface material 35 is provided with the gap 37 with respect to the core material 34 do not necessarily need to be integrated, and can be implemented independently. It is possible.

(Embodiment 4) FIG. 9 shows a dish basket of a dishwasher according to a fourth embodiment of the present invention. Items having the same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

The difference from the configuration of the first embodiment is that the entire surface of the core material 38 having the irregularities 39 on its surface is coated with the surface material 40. Specifically, the core material 38
As for the surface material 40, a wire basket made of iron having the irregularities 39 processed in advance is used to make a tableware basket by bending or welding, and nylon resin coating is performed at the end of the assembly process.
It is what

In the case of a dishwasher, high-pressure washing water is sprayed to clean dirt adhering to the dishes, but relatively light dishes move due to the spraying, which causes friction with the components of the dish basket, resulting in dishwashing. However, according to the configuration of the present embodiment, by coating the surfaces of the constituent members, in addition to the effect of removing water droplets, the frictional force between the table baskets is softened to prevent the tableware from being scratched. Can be prevented.

In addition, in this embodiment, since resin coating can be performed at the end of the process of assembling the tableware basket, it can be manufactured at low cost. Moreover, it is possible to easily manufacture the necessary portions such as the car pins because the uneven portions 39 are formed in advance by processing the core material 38. Further, since the coating is applied to all the core materials 38,
Iron can be used as the material of the core material, which can be realized at a lower cost than when stainless steel is used.

With respect to the material of the surface material 40, various materials such as a polymer material, an inorganic material and an organic material can be used in addition to the nylon resin. Regarding the color, use white material to create a clean feeling, use colored material to color the tableware set in the basket pin of the tableware basket, or use transparent or translucent material. It may be used to emphasize the cleanliness of the stainless steel which is the core material 38.

(Embodiment 5) FIG. 10 shows a tableware basket of a dishwasher according to a fifth embodiment of the present invention. Items having the same reference numerals as those in Examples 1 and 4 have the same structure, and a description thereof will be omitted.

In FIG. 10, the difference from the structure of the fourth embodiment is that the entire surface of the core material 38 is coated with the surface material 40, and the surface material 40 has an uneven portion forming material 41 such as small-diameter particles. That is, the uneven portion 39 is formed by containing

In this embodiment, since the concavo-convex portion 39 can be easily formed without processing the concavo-convex portion 39 into the core material 38 in advance, it can be manufactured at a lower cost. In addition,
The height of the uneven portion 39 of the mixed uneven portion forming material 41 is 0.1.
The diameter is less than that because it is formed from a millimeter to a few millimeters. Regarding the mixing ratio, since the diameter of the target water droplet is within about 10 mm, it is necessary to adjust the mixing ratio so that the interval between the convex shapes in the uneven portion 39 is about 10 mm or less. This depends on the shape of the car pin and should be adjusted accordingly. To give an example, it is considered that the effect of removing water droplets is great even in a satin-like state as the finish of the coated uneven portion 39. In that case, the density of the convex portions can be effective when there are two or more convex portions at intervals of about 10 mm. Further, as the material of the uneven portion forming material 41, glassy material, ceramic material, resin, rubber, metal or the like can be considered.

Further, by changing the material, hardness, size, and mixing ratio of the uneven portion forming material 41, it is possible to easily adjust the water drop adhesion amount and the effect of preventing scratches due to the difference in height and size of the uneven portion 39. Is something that can be done.

[0042]

As described above, the dishwasher of the present invention has a dish basket for storing dishes and the like, and a washing means for spraying washing water to wash the dishes. ,
Since the table material has a surface material that forms irregularities on the surface of the core material, the tableware contacts only the convex parts of the surface material in the table basket, and the contact state approaches point contact, so the contact part It is difficult to form fine gaps in the vicinity, adhesion of water droplets is suppressed, and residual particles and the like are less likely to be caught, so that cleaning performance can be improved. In addition, since the cleaning performance can be improved without increasing the mechanical force such as the cleaning pressure and the flow rate,
There is no adverse effect such as increased cleaning noise.
