Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher and a dishwasher used in homes and the like.

[0002]

2. Description of the Related Art Conventionally, there is a dishwasher of this type as described in Japanese Patent Laid-Open No. 50-26356. This device has a configuration as shown in FIG. 11, in which items to be cleaned such as dishes are stored in a cleaning tank, and the opening 2 provided in the main body 1 is closed by two door bodies 3a and 3b, and then washed. The cleaning water and the rinsing process of the object to be cleaned are performed by the pump injecting the cleaning water. Two doors 3
a and 3b are respectively rotated in the vertical direction to open the opening 2 of the cleaning tank.
It is configured to open and close the door, and the interlocking link 4 allows both doors 3
a and 3b are connected. Therefore, when one door is opened, the other door is opened at the same time.

[0003]

However, in the conventional dishwasher, the two door bodies 3a and 3b are interlocked with each other by the interlocking link 4.
Since the doors are rotatably connected to each other, the opening and closing operations of one door body cause the other door body to operate uniquely. There is no problem as long as processing and assembling are performed with the ideal dimensions, but in reality, there are always part errors due to processing and molding, as well as assembly errors during assembly, etc. I can't go up. Therefore, even if waterproofing is ensured when the individual door bodies 3a and 3b are individually opened and closed, if there is a processing error or an assembly error in the portion related to the interlocking link 4, the door can be placed at the correct position where sealing is possible. The body 3a, 3b cannot be closed. In other words, even if the waterproofing of the doors 3a and 3b alone is secured, there is a problem that a gap is created when the doors are closed and water is leaked during cleaning by uniquely interlocking the plurality of doors. It was. Also, the error also had the possibility that larger and the closing operation is made or, or become impossible heavier.

The present invention solves the above-mentioned problems of the prior art, and prevents the water leakage by closing the door at a correct sealable position even if there is a processing error or an assembly error of parts. To aim.

[0005]

In order to solve the above-mentioned conventional problems, the dishwasher of the present invention is provided with a multi- purpose dishwasher for closing an opening.
When opening and closing a number of doors and one of the doors
The door body with interlocking means for interlocking other door bodies.
Has a lower door body and an upper door body that open and close up and down.
The moving means is located in an operation range for opening and closing one of the door bodies.
Thus, the other door body has an operation area in which it does not interlock .

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

(First Embodiment) FIGS. 1 and 2 are a side view and a sectional view of a dishwasher according to a first embodiment of the present invention. In the figure, there is a cleaning tank 5 provided in the main body 1, and an object to be cleaned 6 such as dishes is set in a cleaning basket 7 and stored in the cleaning tank 5. There is a water supply valve 8 for supplying cleaning water to the cleaning tank 5, a cleaning pump 9 for pressurizing the cleaning water, and a cleaning nozzle 10 for spraying the cleaning water is provided with a plurality of injection holes. Further, in the cleaning tank 5, there are a filter 11 for collecting the leftover food and a heating element 12 for heating, and a temperature sensor 13 for detecting the temperature of the cleaning tank. Also,
A drainage pump 14 for discharging the cleaning water and a blower 15 for sending air to the cleaning tank 5 are provided, and a ventilation path 16 for guiding the air blown by the blower 15 to the cleaning tank 5 is provided, and an exhaust port for discharging the exhausted air. 17 is provided on the door body 18.

Further, two door bodies 18 (a lower door body 19 and an upper door body 20) for closing the opening 2 of the cleaning tank 5 are provided,
The lower door body 19 is rotatably supported on the main body 1 by a pivot shaft 21,
The upper door body 20 includes two rotating arms 2 provided as a supporting means.
2 and 23, the upper door body 20 is pivotally supported by the pivots 24 and 25, and the main body 1 side is pivotally supported by the pivots 26 and 27. An interlocking link 28 is provided as an interlocking means for interlocking the upper and lower door bodies 19 and 20, one end side of which is pivotally supported by a pivot 29 which is integrally formed with the lower door body 19, and the other end side thereof is an upper door body. It is pivotally supported by a pivot 30 on a rotating arm 22 which is a support means for 20. Here, the hole portion 31 of the interlocking link 28 that engages with the pivot 30 has an elongated hole structure provided with play. In addition, the supporting means such as the pivot, the rotating arm, and the interlocking means 28 are the door body 1.
The handle portions 32, which are provided on both sides of the door body 8, for opening and closing the door body 18, are installed on the lower door body 19.

Next, the operation and action will be described. First, the basic operation of the dishwasher will be described. The item to be washed 6 such as dishes is set in the washing basket 7 and then stored in the washing tank 5 and the detergent is put therein. After that, the opening 18 of the main body 1 is closed by the door 18 and the operation of the apparatus is started. The cleaning process for removing stains on the article 6 to be cleaned, the rinsing step for flowing the attached detergent or residual food, and the drying step for drying the water suitable for the article 6 to be cleaned are performed in this order. First, the water supply valve 8 operates to supply a predetermined amount of cleaning water to the cleaning tank 5, and then the cleaning pump 9 pressurizes the cleaning water and jets it from the cleaning nozzle 10. At this time, a heating element 12 such as a sheathed heater provided in the cleaning tank 5
The washing process is performed while heating the washing water. Further, the temperature sensor 13 detects the temperature of the cleaning tank 5, and when the temperature exceeds a predetermined temperature, the power supply to the heating element 12 is stopped.

When the cleaning process for a predetermined time is completed, the cleaning water containing dirt is discharged outside the machine by the drainage pump 14 and new cleaning water is supplied. The cleaning pump 9 is operated, and the cleaning water is sprayed again from the cleaning nozzle 10 to rinse the object 6 to be cleaned, such as detergent and leftover food. After the operation for a predetermined time, the operation of discharging the cleaning water and supplying the cleaning water again is repeated, and this rinsing step is continuously performed about three times.
Finally, the wash water is discharged to the outside of the machine, and the rinsing process is completed.

Subsequently, a drying process is performed, and by operating the blower 15, the outside air is blown into the cleaning tank 5 through the blowing passage 16 and is discharged from the exhaust port 17. At this time, the heating element 12 is energized, and the evaporation of water droplets adhering to the article to be cleaned 6 is promoted by the effects of both the air flow and the temperature. These drying steps are performed for a predetermined time, and the operation is finished.

Next, the door body 18 will be described. The door bodies 19 and 20 divided into two pieces are opened and closed vertically, respectively, and the lower door body 19 is rotated downward by the rotation of the pivot 21. The upper door body 20 moves to the space above the main body 1 by the rotation of the rotary arms 22 and 23 of the book. At this time, the rotating arms 22 and 23 have different lengths, and the upper door body 20 moves while rotating. In addition, interlocking link 2 which is interlocking means
8 is a rotary arm 22 that supports the lower door body 19 and the upper door body 20.
When one of the door bodies is moved, the other door body is also interlocked with the other door body. Therefore, it is not necessary to open the two door bodies 18, and the two door bodies 18 can be opened by one opening operation.
Can be opened all at once and the usability is dramatically improved.

The hole 31 that engages with the pivot 30 has an elongated hole shape, and creates a non-interlocking region by the interlocking link 28. 3 is an intermediate stage diagram when the handle portion 32 of the lower door body 19 is pulled out, and even if the lower door body 19 is moved to the position of FIG. Moves in the radial direction of the shaft, so that the upper door body 20 does not move at all. Next, when the lower door body 19 is further pulled out, the upper and lower door bodies 19 and 20 are interlocked by the action of the connecting link 28, and the upper and lower door bodies 18 are simultaneously opened to the position shown in FIG. In FIG. 4, a is a rotatable range of the lower door body 19, and range b is the upper and lower door bodies 18 among them.
Is the range of interlocking. Further, as shown in FIG. 3, the lower door body 1
Since the upper door body 20 is opened next after the first door 9 is opened, it is possible to prevent water droplets, dirt and the like attached to the upper door body 20 from falling out of the apparatus.

Further, from the open position shown in FIG.
Within the range of the long hole 31 portion of the interlocking arm 28, the upper door body 20
Can be moved without interlocking with the lower door body 19, and only the upper door body 20 can be moved further upward as shown in FIG. As a result, the opening 2 of the cleaning tank 5 can be opened wider, so that the object 6 to be cleaned such as tableware can be easily checked and taken out. Further, if the cleaning basket is drawn out as shown in the figure, it is easier to take in and out the object to be cleaned.

Further, by increasing the play amount of the long hole 31, it is possible to increase the non-interlocking area. For example, when the height of the installation place is low, use it in the state of FIG. When the height is high, it is possible to use the upper door body 20 only by opening it upward.

By adjusting the play amount of the long hole 31, the maximum height when the door 18 is opened can be adjusted, and the upper door 20 is opened to a height corresponding to the height of the actual installation place. By doing so, it is possible to obtain a usage state in which the installation height is fully utilized. Even in the interlocking means other than the present embodiment in which the hole portion of the interlocking link 28 is the elongated hole 31, it is possible to adjust the non-interlocking area and maximize the installation height.

Next, when closing the door body 18 from the open position of FIG. 4, the lower door body 19 is operated to first move to the position of FIG. In this state, the pivot 30 portion has play, so there is freedom in the movement of the upper door body 20.
Since a force acts on the upper door body 20 in the closing direction due to its own weight of 0, the upper door body 20 is in a substantially closed state when the lower door body is at the time of FIG. Then, if the lower door body 19 is pushed back,
Since the interlocking of the upper and lower door bodies 19 and 20 is released by the elongated hole 31, only the lower door body 19 operates and closes to the closed position in FIG. In this closed position, the upper and lower doors 19, 2
0 is not linked and exists as a single door,
If the water resistance of the individual door bodies 19 and 20 is ensured, the opening 2 can be reliably closed in a watertight manner.

There are already various types that can be opened and closed with one door, and waterproofing can be performed relatively easily. However, when a plurality of door bodies 18 are interlocked and interlocking by the interlocking means is performed completely uniquely as in the conventional case, there is no problem as long as processing and assembling are performed with ideal dimensions, and waterproofing is performed. Both doors can be closed at the position where they are kept, but in reality, there is always an error in parts due to processing and molding, an assembly error during assembly, etc., so that the door cannot be assembled as ideal. If the assembly error is multiplied by the part error, the final error may be greatly increased. If the interlocking is unique,
The waterproof is incomplete.

For example, as shown in FIG. 6, when the position of the pivot 30 is slightly deviated, the upper door body 20 is not completely closed and the portion c is stopped in a floating state. Therefore, the sealing of the upper door body 20 becomes incomplete, and water leakage occurs during cleaning. Contrary to FIG. 6, when the upper door body 20 is excessively closed, the lower door body to be operated is not completely closed, and the closing operation becomes heavy, or in a remarkable case, There is a risk that it will not be able to be blocked or damaged.

Therefore, in the vicinity of the closed position, the door bodies 19, 2 are
With the configuration in which 0s are not interlocked with each other, it is possible to close each door body to a position where it can be sealed, and the upper and lower door bodies 19, 2,
Even if 0 is linked, it is possible to reliably prevent water leakage. If the upper and lower door bodies 19 and 20 are provided with respective locking devices, the doors can be securely locked at their respective predetermined positions. Moreover, when a part of upper and lower door bodies 19 and 20 are overlapped, the other door body can be pressed down by the outer door body, and if one door body is positioned at the closed position, the other Can also be positioned.

Further, the rotating arms 22 and 23 and the interlocking means 2
8 are provided on opposite sides of the door body 18, respectively, and the operating force of the interlocking means acts evenly on the left and right sides of the door body, so that the dependent door bodies are prevented from twisting, and the opening / closing operation of the door bodies is prevented. It can be done smoothly.

In this embodiment, in order to provide a region in which the doors are not interlocked with each other, the pivot shaft 30 can be moved in the radial direction of the shaft. Specifically, the hole 31 of the pivot shaft 30 can be lengthened. Although it has a hole shape, other than this, it may be oval,
Various configurations are conceivable, such as a circular shape with a large amount of play, or the shaft shape is a non-circular shape such as an ellipse, or the shaft shape and the hole shape are different. To be

Further, a pivot 30 is provided on the interlocking link 28,
Even if the rotary arm 22 is provided with the elongated hole 31 that engages with the pivot 30, the same operation and effect can be obtained. Also, the axis 30
The same applies to the case where the hole portion of the pivot 29 on the side opposite to is formed in a long hole shape.

Although not particularly shown, a flange portion is provided to prevent the elongated hole 31 fitted in the pivot shaft 30 from coming off, and the material and oil supply are taken into consideration so that the pivot shaft 30 can move smoothly. is necessary.

Further, the opening / closing method of the door body 18 is not limited, and as shown in FIG. 7, the upper door body 20 rotates one support means 33 fixed to the upper door body 20 around the pivot 34. The same effect can be obtained with respect to waterproofing regardless of the configuration. The opening and closing direction is left and right opening,
The same applies when the number of door bodies is three or more.

Although the interlocking means 28 is connected to the door 18 or a supporting means for movably supporting the door 18, the interlocking means 28 may be installed at a location where it moves as the door 18 is opened and closed. The connection location is not limited to the position shown in FIG. Further, when the pivots 21, 26, 27 for installing the door body and the supporting means on the main body 1 are installed on the same member, the error between the door bodies 19 and 20 becomes small.

Further, in FIG. 1 and the like, the pivot shaft, the rotary arm and the like are illustrated as being on the outside of the wall surface for the sake of easy understanding, but they can be housed inside the wall surface of the main body 1 and inside the cleaning tank 5 and By distinguishing the installation area from the outside of the device,
Durability is improved by preventing rust and deterioration, and a good appearance is obtained in which the rotating arm is not exposed to the outside.

Although the opening 2 is the front surface of the main body 1,
The same applies to the top surface, the side surface, or the structure having the openings on a plurality of surfaces. Also, it can be applied not only to the table-mounted type but also to the door of the built-in type dishwasher.

The interlocking means 28 is not limited to the link structure, and may be connected by wires, gears, belts,
Other configurations such as interlocking with a chain may be used. Further, similar to the interlocking link 28 of the present embodiment, it is not limited to mechanical means, and the same action and effect can be obtained by using electric means. For example, a drive motor that opens and closes the upper door body 20 and a position sensor that detects the open / closed position of the lower door body 19 are provided, and the opening degree of the upper door body 20 is adjusted by the drive motor according to the output of the position sensor, and the interlocking operation is performed. It is also possible to set an area to be operated and an area not to be linked.

It should be noted that the present invention relates to the opening / closing structure of the door body 18, and does not limit the cleaning or drying method or configuration, the operation mode, or the like. Although the example of the dishwasher having a drying function is shown in the embodiment, the door of the present invention can be applied to a dishwasher not having a drying function, a tableware dryer that only performs drying, or another device such as a storage device. The structure is available.
The same applies to the other examples.

(Second Embodiment) FIG. 8 is a side view of a dishwasher according to a second embodiment of the present invention.
The same components as those in the first embodiment shown in FIG. 1 are designated by the same reference numerals. As shown in FIG. 8, the interlocking link 28, which is the interlocking means, is provided with an extendable / contractible portion 35, and the upper door body 20 is configured to rotate and open about a pivot 36. In addition, an elastic body (compression spring) 37 that acts in a direction of contracting the expandable part 35 is installed in the expandable part 35.

Basically, the same effect can be obtained as in the case where the pivot portion shown in the first embodiment is movable. At the closed position of the door body 18, each door body is independent by the expansion / contraction portion 35, and each door body 19, 20 can be closed at a sealable position, and the upper and lower door bodies 18 are interlocked. Nevertheless, it can be reliably blocked and water leakage can be prevented. Further, it is possible to further open only the upper door body 20 when opening.

The elastic body 37 provided on the expansion / contraction portion 35 is
Since the interlocking link 28 operates in the direction of compressing the expansion / contraction portion 35 and has the shortest length, when the handle portion 32 of the lower door body 19 is held and closed, the upper door body 20 is closed first. To do. Then, in the vicinity of the closed position, the force for closing the lower door body 19 causes the upper door body 20 to receive a force in the closing direction. Further, when the lower door body 19 is pushed further toward the closed position, the biasing force of the compression spring 37 acts in the direction of closing the upper door body 20 and the upper door body 20 can be held at the closed position. As a result, the upper door body 20 is closed first,
Next, the lower door body 19 is closed, and the door body 18 is closed.
Although there is a region in which the doors do not work together, the door body 18 can be closed in a fixed order. Since the order of closing the doors is indeterminate, it is possible to prevent the doors 18 from coming into contact with each other and being damaged, and to reliably close all the doors 18,
The sealing property can be secured.

When the elastic body 37 is operated,
Even if the weight of the door (upper door body) other than the operated door body does not act in the closing direction, the door body can be closed first, so the upper door body can be operated to open and close the upper and lower door bodies. The same effect can be obtained even when the door is opened or closed.

Even when a play is provided such that the pivot 30 is formed in the elongated hole 31 shape as in the first embodiment, the elastic body 37 acts in the compression direction so that it is as shown in the present embodiment. The effect is obtained. When another elastic body is installed in the closing direction of the upper door body 20, a force in the closing direction is always applied to the upper door body 20.
Since the upper door body is always closed first and the closing order is constant, smooth and reliable closing operation can be performed.

(Embodiment 3) FIG. 9 is a side view of a dishwasher according to Embodiment 3 of the present invention.
The same components as those in the first embodiment shown in FIG. 1 are designated by the same reference numerals. As shown in FIG. 9, the interlocking means is the interlocking wire 38, and the connecting portion 39 is installed on the lower door body 19 and the connecting portion 40 is installed on the upper door body 20, and the connecting portion 40 on one end side of the interlocking wire 38 can be moved. Is provided.

As shown in FIG. 9, the connecting portion 40 includes the sliding portion 4
Since the door body 18 is moved by 1, the respective door bodies 19 and 20 are independent at the closed position of the door body 18, and each door body 19 and 20 can be closed to a sealable position.
Even though 8 is interlocked, water leakage can be reliably prevented.

When interlocking using the interlocking wire 38, unlike the case of the link, the interlocking force in the closing direction does not act, but the own weight of the upper door body 20 acts in the closing direction as shown in FIG. In this case, if the lower door body 19 is moved in the closing direction, the upper door body 20 is also closed, so that the upper and lower door bodies 18 can be interlocked in both opening and closing directions. Also, the upper door body 20
When the elastic body for urging the door is actuated in the closing direction, the upper door body 20 is surely closed, so that the opening / closing operation can be interlocked regardless of the presence or absence of the effect of its own weight. Further, due to the action of this elastic body, the biasing force of the elastic body acts in the closing direction in the vicinity of the closed position, so that the closing order becomes constant and reliable sealing is possible.
