Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dish basket used in a dishwasher by being housed in a washing chamber.

[0002]

2. Description of the Related Art In a dishwasher, water is supplied from a water supply source to a washing room in which dishes are stored, and water stored in the bottom of the washing room is sent out to a washing nozzle by a pump, and the washing nozzle is perforated. The tableware is washed and rinsed by injecting water from the water injection hole to the tableware.

[0003] In this type of dishwasher, various shapes of tableware, chopsticks, spoons and other auxiliary tools used in ordinary households are efficiently stored in the washing chamber, and water sprayed from a washing nozzle is used. Tableware baskets that can be used to stand dishes and the like are used so that they can descend evenly.

Conventionally, such a dish basket is formed by bending a metal wire such as iron having an appropriate strength into an appropriate shape, and spot welding a plurality of wires together. Then, the basket is immersed in, for example, a liquid nylon resin to form a protective film layer having an appropriate thickness on the surface of the wire. Such a resin coating can prevent rust of the metal wire.

[0005]

However, the resin coating layer is easily damaged by a sharp knife such as a kitchen knife. In the dishwasher, since water falls on the dish basket almost continuously during use, rust is easily generated at the above-mentioned damaged portion. In addition, when the resin coating layer is formed, the diameter of the wire constituting the tableware basket becomes large, which hinders the passage of the washing water, and the washing ability may not be sufficiently exhibited, for example, leaving unwashed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a dishwasher tableware which can maintain cleanliness for a long period of time and does not impair the washing ability. To provide baskets.

[0007]

Means for Solving the Problems, Embodiments of the Invention, and Effects of the Invention According to the present invention, which has been made to solve the above-mentioned problems, an object to be cleaned is accommodated in a cleaning room, and is disposed in the cleaning room. In a spray-type dishwasher for washing an object to be washed by spraying water from a water spray hole of a nozzle, a dish basket to be installed inside the washing chamber, which is constituted by a wire made of stainless steel. It is characterized by becoming.

That is, a dish basket made of a stainless metal wire does not rust even if the wire is scratched by contact with a blade or the like. In addition, scales and the like hardly occur. For this reason, it can be used hygienically over a long period of time, and the appearance is well maintained. In addition, the diameter of the wire can be reduced by the amount of the resin coating layer as compared with the conventional resin coating layer formed on the surface, so that the ratio of the water injected from the water injection hole is reduced. In addition, the possibility of uneven cleaning or rinsing is reduced.

Further, the tableware basket according to the present invention comprises an outer frame formed in a substantially box shape, and a plurality of tableware holding members erected substantially in parallel with a predetermined interval between a pair of opposite sides of the outer frame. Each tableware holding member can be configured to be capable of holding a plurality of tablewares in a direction of extension by bending a single wire.

That is, in the above-mentioned tableware basket, for example, a dish is stored in an appropriate position between two adjacent tableware holding members in a state of standing upright. Then, the bent portions of the tableware holding members come into contact with the front and back surfaces of the dish, and are stably held without rattling. Further, another dish is similarly accommodated between the two tableware holding members adjacent to the dish.

In the conventional tableware basket, a tableware holding member for holding the tableware is individually provided for each tableware, so that the total number of wires is large, and welding work is performed while holding each wire. Since it had to be done, the labor of assembly was also difficult. On the other hand, according to the above configuration, the number of wires to be used can be significantly reduced as compared with the related art. Further, at the time of assembling, welding portions at both ends of one wire are first welded, and then welding portions at the central portion may be sequentially welded, so that assembling labor is reduced. For this reason, manufacturing costs can be significantly reduced.

Further, in the tableware basket according to the present invention, a basket body formed of a stainless steel wire and capable of holding and holding tableware in an upright state, and a resin detachably mounted on an upper portion of the basket body. And a movable mounting shelf formed of a wire having a layer coated on the surface.

In such a two-stage tableware basket, relatively large areas of tableware, such as plates, are stored in the basket main body, while relatively small dishes, such as cups and teacups, are placed on the mounting shelf. Tableware can be placed face down. Therefore,
Many dishes can be efficiently stored in a small bottom area. In addition, the wires may collide with each other when moving the movable mounting shelf. However, it is possible to prevent the resin coating layer from becoming a cushioning material and generating a large collision noise. Further, since the cups, teacups, and the like placed on the mounting shelf are not individually held, for example, when the tableware basket is housed in the washing room, it is easy to slide on the mounting shelf. When applied, the friction increases, so that the slipping of cups, teacups and the like is suppressed.

Further, in the tableware basket according to the present invention, both ends of the one wire constituting the tableware holding member are cut substantially horizontally at the upper end of the outer frame so as to face substantially vertically upward. Is preferred.

That is, in general, burrs are easily formed on a cut surface of a stainless steel wire, so that it is necessary to remove burrs by mechanical polishing or the like. When both ends of the wire are oriented substantially vertically upward as in the above configuration, the polishing of both ends can be performed from the same direction, so that the polishing process is efficient and the manufacturing cost can be reduced.

Further, in the dish basket according to the present invention, the stainless wire becomes hot when it comes into contact with high-temperature hot water during washing, so that the stainless steel wire can be easily gripped by the user immediately after washing the dish. It is preferable to provide a grip portion made of resin or the like.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a tableware basket according to an embodiment of the present invention. First, the configuration of a dishwasher using the dish basket of the present embodiment will be described with reference to FIG. FIG. 1 is a side sectional view of the dishwasher. A washing room (also serving as a drying room) 2 is provided inside the machine casing 1, and a dish basket 20 for accommodating tableware is loaded therein. Cleaning room 2
A door 3 whose lower end is pivotally supported is provided in the front opening of the front door so as to open in the front direction. A rotatable nozzle arm 4 is provided at the center of the bottom of the cleaning chamber 2, and an ejection hole 5 is formed at a predetermined angle on the upper surface thereof. A water tank 6 provided with a circulation port 7 and a drain port 8 is disposed in front of the bottom of the washing chamber 2. Filter 9 is provided.

A cleaning and drainage pump 1 is provided at the outer bottom of the cleaning chamber 2.
0 is disposed, the water sucked from the circulation port 7 of the water storage tank 6 is sent out to the nozzle arm 4 at the time of washing, and the water sucked from the drain port 8 of the water storage tank 6 is discharged to the outside through the drain hose 11 at the time of drainage. On the other hand, water supplied from outside via the water supply valve 12 is poured into the cleaning chamber 2 from a water supply port 13 provided behind the cleaning chamber 2. A water level detection chamber 14 having a float (not shown) for detecting the water level in the cleaning chamber 2 is disposed below the rear wall of the cleaning chamber 2, and the water in the cleaning chamber 2 is connected to a communication port (not shown). The water also flows into the water level detection chamber 14. Further, a loop-shaped sheathed heater 15 for warming the washing water and rinsing water and increasing the temperature of the air in the washing chamber 2 at the time of drying is provided from the vicinity of the center of the bottom of the washing chamber 2 to the rear.

When washing dishes using the dishwasher, the user stores the dishes in the dish basket 20, opens the door 3, and places the dish basket 20 inside the washing room 2. When the washing is started, the water supply valve 12 is opened, and a predetermined amount of water is stored at the bottom of the washing chamber 2. This water is sheathed heater 1
5 to a predetermined temperature (usually about 60 ° C.). When the washing / draining pump 10 is driven, the washing / draining pump 10 sucks water from the circulation port 7 of the water storage tank 6 and sends out the water to the nozzle arm 4. The water rushes out of the small-diameter jet hole 5 and the nozzle arm 4 rotates by the reaction of the jet of water. As a result, the water hits the tableware stored in the tableware basket 20 and flows down to the bottom of the washing room 2, where solids are removed by the filter 9 and circulated to the water storage tank 6. When the washing for a predetermined time (about 10 minutes) is completed, the washing and drainage pump 10 discharges the water sucked from the drainage port 8 of the water storage tank 6 to the drainage hose 11 and discharges the water at the bottom of the washing chamber 2.

After that, the water supply valve 12 is opened, clean water for rinsing is newly introduced into the cleaning chamber 2, and rinsing is performed for about one minute in the same manner as in the cleaning. After rinsing with water is repeated two or three times, water is introduced into the cleaning chamber 2, and the water is heated to a temperature of about 70 to 80 ° C. by the sheath heater 15. Then, final rinsing is performed with the hot water. Thereby, the tableware can be sterilized, and the tableware is warmed, so that quick drying can be performed at the time of the next drying operation.

Next, the configuration of the tableware basket 20 of this embodiment is shown in FIG.
This will be described with reference to FIG. 2 and 3 are external plan views of the tableware basket 20 according to the present embodiment. FIG. 2A is a top view and FIG.
(B) is a front view, and FIG. 3 is a side view. 4 is an external plan view of only the basket main body 30 in FIG. 2, FIG. 4 (a) is a top view, FIG. 4 (b) is a front view, and FIG. 4 (c) is a side view.
FIG. 5 is a view showing an example of a state in which a dish is accommodated in the basket main body 30, FIG. 5 (a) is a side view, and FIG. 5 (b) is a sectional view taken along line BB in FIG. 4 (a). . FIG. 6 is an external plan view showing two types of tableware holding members installed in the front-rear direction on the bottom of the basket main body 30. Here, the surface located on the door 3 side when the tableware basket 20 is installed in the washing room 2 of the dishwasher is the front.

As shown in FIGS. 2 and 3, a tableware basket 20 according to the present embodiment has a box-shaped basket body 30 mainly suitable for arranging dishes and cutting boards and the like, and is detachably mounted on the upper part of the basket body 30. An upper basket 40 suitable for placing and placing cups and the like freely used and used.

As shown in FIG. 4, the basket main body 30 has two outer frames 31 formed into a substantially rectangular shape, and one outer frame 31 having both ends welded to the inside of opposing front and rear sides of the outer frame 31. First, second, third tableware holding members 32a, 32
b, 32c, a plurality of first horizontal support members 33a formed of a U-shaped wire rod whose both ends are welded to the inside of the opposite sides of the outer frame 31 at both ends, and the first horizontal support Member 3
3a and two second horizontal support members 33b attached to the bottom surface in parallel. The first and second horizontal support members 33a and 33b and the first to third dish holding members 32a and 3b
2b and 32c are connected by spot welding at the intersections of the bottom surfaces. All members constituting the basket main body 30 are formed of a wire made of stainless steel, and the diameter of the wire is 4 mm at the upper part of the outer frame 31, 3.5 mm at the lower part of the outer frame 31, and 2.5 mm at the other members. It has become. When the resin coating layer is formed on the surface of the wire rod as in the related art, it is necessary to form a layer having a thickness of about 0.5 mm. However, such a resin coating layer is unnecessary in the tableware basket according to the present invention. Therefore, the diameter of each member can be made smaller by about 1 mm than in the related art. Of course, the diameter of the wire can be changed as appropriate.

First to third dish holding members 32a to 32c
Is obtained by bending a single wire into a shape as shown in FIGS. 6 (a) to 6 (c). Both ends of each wire are substantially vertically upward, and extend longer than the upper end of the outer frame 31 at the time of bending. Then, as shown in FIG. 4 (c), after being attached to the outer frame 31, the upwardly extending portion is cut horizontally at the position of the line C in FIGS. 6 (a) to 6 (c). Since such cuts cause burrs on the cut surface, the burrs are removed by polishing the cut surfaces at both ends in the same direction.

In the basket main body 30, the first to third tableware holding members 32a to 32c are laid in parallel at predetermined intervals. Therefore, as shown in FIG. 5, it is possible to hold large and small plates 51, 52 side by side between two adjacent first tableware holding members 32a or second tableware holding members 32b. .

On the other hand, as shown in FIGS.
In the case 0, the connecting member 34 made of polypropylene resin or the like is fitted into the outer frames 31 before and after the basket main body 30, and the upper basket outer frame 41 is fixed to the connecting member 34 with the screws 35, whereby the basket main body 30 is mounted. The upper basket 40 is provided with a mounting shelf 42 that can freely swing around a shaft 43. When the mounting shelf 42 is rotated in the direction of arrow A2 in FIG. Reference numeral 42 substantially vertically contacts the side of the upper basket outer frame 41 and is held vertically. Thereby, the height limitation by the mounting shelf 42 is eliminated, and tall tableware can be stored also in the basket main body 30 below the upper basket 40. Conversely, when the mounting shelf 42 is rotated to the position of the stopper 44 in the direction of arrow A1 in FIG.
The mounting shelf 42 is held substantially horizontally, and relatively small tableware such as cups and teacups can be placed side by side on the mounting shelf 42. Of course, in this case, small dishes can be stored in the basket main body 30 below the upper basket 40 as shown in FIG.

The upper basket 40 may be made of a wire made of stainless steel similarly to the basket main body 30. However, like the conventional tableware basket, the basket is made of a wire made of iron, and May be immersed in a liquid nylon resin to cover the surface of the wire with the resin. In the upper basket 40, for example, when the mounting shelf 42 is rotated, the lower surface of the mounting shelf 42 collides with the stopper 44, but the collision sound is reduced with the wire having the resin coating layer formed thereon. In addition, the noise when placing a cup or the like on the placing shelf 42 is also reduced. Furthermore, since the surface of the resin coating layer has a greater friction than stainless steel, the placed cup or bowl can be prevented from slipping.

Next, another embodiment of the tableware basket 20 according to the present invention will be described with reference to FIG. FIG. 7 is a plan view of the appearance of the tableware basket of the present embodiment, similarly to FIG. 2, wherein FIG. 7A is a top view and FIG. 7B is a front view. Tableware basket 20 of the present embodiment
In the figure, a gripping member 36 formed integrally with the connecting member 34 is attached to a front portion of the outer frame 31. The gripping member 36 is made of, for example, polypropylene resin or the like,
Thermal conductivity is much smaller than stainless steel. For this reason, even if it is exposed to hot water or hot air at the time of washing the dishes, it does not easily become hot, and after washing the dishes, the user can grasp the gripping member 36 and pull the dish basket 20 forward.

The above embodiment is merely an example, and it is apparent that modifications and changes can be made within the spirit of the present invention.
