【Example】
Embodiments of the present invention will be described below with reference to the drawings. In addition, description is abbreviate | omitted about the structure of the dishwasher demonstrated in the prior art example.
[0017]
Example 1
FIG. 1 is an external view of a tableware basket of the tableware dryer according to the first embodiment of the present invention, and FIG. 2 is a partially enlarged view of components such as a basket pin constituting the tableware basket and holding the tableware.
[0018]
As shown in FIG. 1, the tableware basket 14 is formed by joining wires that are assembled horizontally, vertically, and diagonally, and includes a frame, a basket pin for holding the tableware T to be set, and the like. Although FIG. 1 shows a configuration having rod-shaped cage pins 15 , a configuration in which wires are combined in a lattice shape without using rod-shaped cage pins may be used, and a dish or the like can be stood between the lattices. There is also a tableware basket. Further, as shown in FIG. 2, the surface of the component member 15 such as a basket pin constituting the tableware basket 14 is formed with irregularities 16 by providing a streaky spiral groove (recess) on the surface of the bar. The tableware T such as a set dish or a cup is supported by being placed on or leaning on a component member. In this state, the drying of the tableware T is promoted by drying means such as a blower.
[0019]
By using the surface-shaped component member 15, the tableware T comes into contact with only the convex portions 17 of the component member 15 of the tableware basket 14, and the contact state approaches point contact, as shown in FIG. The unevenness 16 acts to reduce the amount of water in the water droplets collected at the contact portion 18 between the set tableware T and the component 15 of the tableware basket 14. The shape of the concave portion 19 of the concave and convex portion 16 is such that the surface portion of the component member 15 is wider than the inner side, and the bottom portion of the concave portion 19 is narrowed. Since water is drawn into the recessed portion 19 and this moisture can be removed, there is no large water droplet at the contact portion 18, and the drying speed is increased and the drying performance is improved.
[0020]
In general, the drying performance is evaluated by the number and amount of water droplets attached to the tableware after a predetermined time, or the time until the water droplets become a certain amount.
[0021]
In addition, the shape of the irregularities 16 in FIG. 3 is such that the angle B of the tip portion 20 of the convex portion 17 is set to an acute angle, and the angle between the tableware T and the convex portion 17 is 90 degrees or more. It can prevent adhesion. The acute angle refers to an angle smaller than 90 degrees, but is preferably as small as possible. Further, even if the wall surface of the convex portion 17 has a parallel columnar shape with an angle of 0 degree, the width of the convex portion 17 needs to be several mm or less, and about 0.5 to 3 mm is practical. It is.
[0022]
In addition, the tip of the convex portion 17 has an R shape in order to prevent the tableware T from being damaged. However, it is desirable that R is as small as possible because water droplets are less likely to adhere to the vicinity of the contact portion 18. For example, if R2 or less, a sufficient effect can be obtained.
[0023]
Note that this effect is to remove the water droplets at a level that can be visually confirmed. The micro unevenness 16 on the surface of the constituent member 15 is not effective, and the height of the unevenness 16 of about 0.1 mm to several mm is obtained. is necessary. The unevenness 16 having a height of about 0.5 mm to 3 mm is a practical size with which an effect is obtained, and a wire 15 of about 3 mm to 6 mm is used for the component member 15 of a general tableware basket 14. What is necessary is just the unevenness | corrugation 16 height of about 1/10 to a little less than 1/2 of 17 diameters. Moreover, although the space | interval, density, etc. of the convex part 17 influence performance, when the tableware is set, the tableware should just contact the convex part 17. FIG.
[0024]
Further, the concave portion 19 of the concave and convex portion 16 is formed by forming a groove portion in the shape of a streak on the surface of the component member 15, and the water drawn into the concave portion 19 by the contact portion 18 of the tableware T and the tableware basket 14 is removed. It can be moved along the (concave portion 19). In particular, since the groove portion (recessed portion 19) is inclined from the horizontal, the moisture moves downward of the component 15 and drops from the lower end portion as shown in FIG. The water supplied to the contact portion 18 can be continuously discharged. For this reason, even when a large amount of moisture is present in the tableware or the like, moisture does not stay in the contact portion 18, and the amount of water droplets can always be reduced .
[0025]
Moreover, even if this unevenness | corrugation 16 is formed by the regular spiral groove and the contact position of tableware and the structural member 15 changes, such as when the size of tableware differs, the same effect | action and effect can be acquired. . Further, the shape shown in FIG. 2 is used for the horizontal basket pin 15, and the vertical basket pin 15 that supports the back of the tableware has an axial streak shape as shown in FIG. 5. By adopting a simple shape, a high-performance tableware basket 14 can be configured. In the example of FIG. 5, the concave and convex portions 16 are provided only at the tip portion of the car pin 15, so that the cost can be reduced. In particular, as shown in FIG. 5, in the case where the lower part in the vertical direction is composed of a member without the irregularities 16, the water droplets are less likely to stay below the irregularities 16. Accordingly, the ability to discharge downward increases, and the amount of water droplets adhering to the vicinity of the contact portion 18 with the tableware can be further reduced. Moreover, it is not necessary to provide the unevenness | corrugation 16 in the site | parts with little possibility of tableware contacting, such as a frame. Moreover, it is not necessary to install the unevenness 16 on the back side of the car pin 15 that contacts the tableware.
[0026]
In addition to the shape of FIG. 2, it is not a spiral groove as shown in FIG. 6, or a configuration in which a coiled separate body is wound around the core material as shown in FIG. 7. However, various shapes such as a mesh-like groove shape (recessed portion 19), a core material coated with a separate mesh, or the like can be used. Incidentally, even in the case of FIG. 7, the cross-sectional shape of the recess 19, the surface portion C of the component 15, which is wider than the portion of the interior side D, similarly to FIG. 2, the recess 19 of moisture by capillary action Can be pulled inside.
[0027]
Moreover, this effect is an effect by the shape of the structural member 15, and the formation method of the unevenness | corrugation 16 is not ask | required, but when the unevenness | corrugation 16 is provided in the structural member 15 itself like FIG. Since the component 15 can be easily manufactured by rolling or rolling, the cost can be kept low. Moreover, there is no fear that the convex part 17 can be taken and high durability is obtained. On the other hand, when the convex portion 17 is formed of a separate member as shown in FIG. 7, it is possible to combine different materials. For example, the core material is made of metal and the convex portion 17 is made of resin. The effect of preventing the tableware from being damaged can also be obtained.
[0028]
Further, although the material of the component member 15 is not limited, it is desirable that the surface is made of resin or rubber in consideration of damage to the tableware. In this case, even when the tip end angle of the convex portion 17 is an acute angle or the tip R is made small, the tableware can be sufficiently prevented from being damaged. Also, a combination of different materials such as a metal core material and a resin protrusion 17 on the surface may be used. However, in order to remove water droplets, it is desirable that the surface be as hydrophilic as possible.
[0029]
In addition, this invention is related to the tableware basket 14, It does not limit regarding the system and other structure of a drying apparatus. Of course, the same effects can be obtained even with a simple water basket or a dishwasher having a function of washing dishes.
[0030]
(Example 2)
FIG. 8 is a partially enlarged view of the tableware dryer according to the second embodiment of the present invention, and the same components as those in the first embodiment shown in FIG.
[0031]
As shown in FIG. 8, the dotted | punctate convex part 17 is discretely provided in the surface of the structural member 15 of the tableware basket 14, and it forms in the satin shape. In this case, since the concave portion 19 is continuously present, the water removed from the contact portion 18 between the tableware and the tableware basket 14 can be guided downward, and even when a large amount of moisture exists, the effect of removing water droplets can be achieved. Can be maintained.
[0032]
Further, since the recess 19 has no directionality, moisture can be moved downward even when irregularities 16 are irregularly formed, and moisture can be discharged. When the irregularities 16 are irregularly formed, all the car pins 15 can be formed of members on the same surface in order to select the installation direction of the car pins 15 such as the horizontal and vertical directions, thereby reducing processing man-hours and costs. be able to.
[0033]
In addition, the shape of the convex part 17 is not limited to a point shape or a spherical shape, Other shapes, such as strip shape and random, may be sufficient. Moreover, this convex part 17 may be installed regularly. Further, or formed as separate members projecting portion 17 on the surface of the core material, also forming the irregularities 16 on the surface by Kotin grayed the resin material on the core material comprising the particles.
[0034]
【The invention's effect】
