DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(7) Hereinafter, reference will be now made in detail to the preferred embodiments of the present invention with reference to the attached drawings.

(8) Referring to FIG. 1 to FIG. 6, a washing ball case for a dishwasher according to the present invention include a case body 100 formed by thermally bonding a top plate 10 and a bottom plate 20 to each other in the vertical direction, which are formed of a synthetic resin material and have holes 11, 21, wherein washing balls 30 formed of a synthetic resin material are accommodated in the internal space part of the case body through a ball insertion hole 110 of the case body so as to be used for washing dishes and the ball insertion hole 110 is closed by a cover 40.

(9) In particular, through holes 120 communicating with the internal space part are formed in the outer side portion of the case body 100 and vertically positioned at the lower part at the time of washing dishes such that washing water is completely drained therethrough.

(10) Herein, it is preferable that the through holes 120 are formed at least at one or more uniform angle positions (at both side positions as shown in the drawings) in the outer side portion of the case body 100.

(11) Further, the through holes 120 formed in the outer side portion of the case body 100 are formed to correspond to each other in the top plate 10 and the bottom plate 20. Therefore, the through holes 120 are used for the drainage of the washing water as described above and also used for the prevention of the movement of the top plate and the bottom plate by inserting fixing pins 210 of a fixing device 200 into the through holes 120 during the thermal bonding of the top plate 10 and the bottom plate 20, thereby preventing bonding defects.

(12) That is, the through holes 120 formed in the outer side portion of the case body 100 are used for both of the function of draining the washing water therethrough in the dish-washing and the function of fixing the top plate and the bottom plate by the fixing pins inserted thereinto in the thermal bonding of the top plate and the bottom plate.

(13) In addition, reference grooves 130 are formed in the vertical direction on the outer side portion of the case body at the same positions of the top plate 10 and the bottom plate 20 and inserted by support bars 300 when thermally bonding the top plate 10 and the bottom plate 20 such that the thermal bonding positions of the top plate and the bottom plate are uniformly maintained, preventing bonding defects.

(14) Herein, it is preferable that the reference grooves 130 are formed in a semi-circular shape, but the reference grooves 130 may be also formed in any other shape. Similarly, even though the case body 100 is shown in a circular shape in the drawings, it is also possible to form the case body 100 in the shape of a square or any other various shape.

(15) Reference sign 400, which is not explained hereinabove, denotes a hot plate.

(16) Hereinafter, the operations of the present invention described as above will be reviewed in detail.

(17) First, the case body 100 is formed by thermally bonding the top plate 10 and the bottom plate 20 to each other in the vertical direction, wherein the top plate 10 and the bottom plate 20 are formed of a synthetic resin material and have holes 11, 21 respectively.

(18) Explaining more specifically, after melting the bonding portions by inserting the hot plate 400 between the top plate 10 and the bottom plate 20, the top plate 10 and the bottom plate 20 are pressed in a state, in which the hot plate is removed, thereby carrying out the thermal bonding.

(19) Herein, the top plate 10 and the bottom plate 20 of the case body 100 are provided with the reference grooves 130 in a semi-circular shape at the same positions in the vertical direction on the outer side portions thereof and the support bars 300 are positioned on the reference grooves 130 such that the top plate 10 and the bottom plate 20 are subject to the thermal bonding in the vertical direction at predetermined positions.

(20) Further, the through holes 120 formed in the outer side portion of the case body 100 are formed to correspond to each other in the top plate 10 and the bottom plate 20. Therefore, when the top plate 10 and the bottom plate 20 are pressed to be molten and bonded to each other, the fixing pins 210 of the fixing device 200 are inserted into the through holes 120 in the outer side portions of the top plate 10 and the bottom plate 20, as shown in FIG. 6, such that the thermal bonding of the top plate 10 and the bottom plate 20 is carried out while fixing the top plate 10 and the bottom plate 20 to prevent any possible movement thereof.

(21) That is, when the case body 100 is formed by the thermal bonding of the top plate 10 and the bottom plate 20, the top plate and the bottom plate are bonded at uniform positions and simultaneously fixed to avoid the movement thereof by using the through holes 120 and the reference grooves 130, which are provided to the outer side portions of the top plate and the bottom plate, thereby preventing the bonding defects resulted in the prior art.

(22) The washing ball case according to the present invention is manufactured as described hereinabove.

(23) The washing ball case manufactured as above is used after the washing balls 30 formed of a ceramic material are inserted into the internal space part through the ball insertion hole 110 of the case body 100 and the ball insertion hole 110 is closed by the cover 40.

(24) That is, the case body 100 is set to stand between dishes in a dishwasher, wherein dish-washing is carried out while spraying washing water in a state, where the case body 100 is set to stand such that the through holes 120 at the outer side portion of the case body are positioned at the lower side thereof.

(25) Herein, dishes can be effectively washed, without using detergent, through the antibacterial and purifying action and the like by the far-infrared radiation from the washing balls 30.

(26) Further, after the dish-washing is finished, the washing water in the case body 100 is completely drained through the through holes 120. Therefore, the washing balls 30 in the case body can be maintained in a dry state such that the washing efficiency of the washing balls can be maximized when washing dishes later.

(27) That is, the washing balls 30 are induced to exhibit the maximum washing efficiency thereof in a dry and smooth state.
