Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a dishwasher for washing objects to be washed such as dishes.

[0002]

2. Description of the Related Art For example, in a domestic dishwasher, a box-like washing chamber is provided for washing objects to be washed, and the dishes are placed in a dish basket. Held in. Further, an opening and an opening / closing door that covers the opening are provided on the front surface of the cleaning chamber in order to put the dishes in and out of the cleaning chamber.

The opening / closing door is usually formed in the shape of a rectangular plate and is rotatably supported. The central axis of rotation is provided in parallel near the lower edge of the door. The opening / closing door is arranged along the front surface of the dishwasher to cover the opening, and is folded down to be substantially horizontal to open the opening. When loading and unloading tableware, the tableware basket can be pulled out from the washing chamber onto the open / close door, and the entire tableware basket can be placed on the open / close door. As a result, the tableware can be easily attached and detached, and the tableware basket can be easily carried.

On the other hand, in the above-mentioned dishwasher having an opening / closing door, since the space for opening / closing the opening / closing door is large,
You may not be able to install a dishwasher. For example, if you try to install the dishwasher sideways on the upper side of the sink with the opening / closing door facing the sink, even if you try to open the opening / closing door, the opening / closing door collides with the faucet. After all, I can't install a dishwasher.

A single-plate open / close door in which the central axis of rotation is provided in the vicinity of the upper edge of the open / close door in parallel therewith is also conceivable.
With this opening / closing door, it is possible to prevent the opening / closing door and the faucet from colliding with each other as described above, so that the dishwasher can be installed sideways on the upper surface which is a side of the sink. On the other hand, since the open / close door is flipped up when opened, it is expected that the shelf provided above the sink and the open / close door will collide. For this reason, it is considered that the opening / closing door can be folded so that the shelf and the opening / closing door do not collide with each other.

In both of the above-mentioned two types of opening / closing doors having the central axis of rotation at the upper edge, the tableware basket cannot be placed on the door, and it is troublesome to take the tableware in and out of the washing room.
Because the washing room is small, it is difficult to put the dishes on the dish basket. In addition to the fact that the combined weight of the object to be cleaned and the tableware basket is quite heavy, and the periphery of the tableware basket is narrow, it is difficult to lift the tableware basket out of the washing room and take it out.

Therefore, the object of the present invention is to solve the above-mentioned technical problems and to install the apparatus on the sink without any trouble.
It is an object of the present invention to provide a dishwasher that can easily put in and take out dishes.

[0008]

SUMMARY OF THE INVENTION The present invention has a shape that is short in the front-rear direction and long in the left-right direction in a plan view, and has an opening in the front surface through which articles to be washed such as dishes are washed. a cleaning chamber for cleaning the object to be cleaned which contains therein can out, is accommodated removably inside the cleaning chamber, the dishes basket for holding the object to be cleaned with the cleaning chamber, the upper <br/> An opening / closing door that covers the front opening of the cleaning chamber, wherein the opening / closing door has an upper door and a lower door arranged side by side in the vertical direction, and the opening / closing door has the upper door in the open state. Along with opening upward, the lower door opens downward around a rotation shaft provided in the lower part, the upper door and the lower door are separated from each other, and the tableware basket is in a state in which the lower door is opened. , So that it can be placed on the lower door by pulling it out of the cleaning chamber. The, the most forward of the above dishes basket
When pulled out, the center position of the tableware basket in the front-rear direction is
Set the tableware cover so that it is behind the rotation axis of the lower door.
Providing a dishwasher, characterized in that a stopper for restricting the mounting position of the rubber.

[0010]

According to the present invention, since the opening / closing door is divided into the small-sized upper door and the lower door, the space for opening / closing the entire opening / closing door is smaller than that of the pivotally supported single-plate opening / closing door. Can be made smaller.

Therefore, it is possible to realize a dishwasher which can be installed on the sink without any trouble. For example, when installing the dishwasher horizontally on the upper side of the sink, when opening the open / close door, the lower door collides with the faucet of the sink, and the upper door is installed above the sink. You can prevent it from colliding with a closet.

Moreover, since the upper door and the lower door can be closed next to each other, the opening / closing door as a whole can cover an opening of substantially the same size as the conventional opening / closing door. Furthermore, since the tableware basket can be pulled out to the lower door, the tableware can be easily taken in and out. Moreover, since a part of the tableware basket is placed on the lower door, it is preferable to secure the amount of tableware held in the tableware basket while downsizing the lower door.

Further, since the washing chamber can be made thin, for example, it is possible to realize a dishwasher which can be installed even when the space on the side of the sink is narrow when viewed from the front.

Further, since the tableware basket corresponding to a thin washing room can be made thin, the tableware can be pulled out far enough when it is pulled out to the lower door, which makes it easier to put the dishes in and out.

In a dishwasher having a thin washing room, if the dish basket is placed on the opening / closing door, it is likely that the dish washer will fall over easily. However, a part of the dish basket is placed on the lower door. However, the dishwasher is hard to tip over.

When the upper door is opened while water drops are attached to the inner surface of the opening / closing door, it is assumed that the water drops attached to the upper door will fall to the surroundings. It is also possible to open the door first, and as a result that the lower door can receive water droplets falling, it is possible to prevent water from getting wet around.

With the hook arm 66 in the vicinity of the second position, the upper engaging portion 39 and the protrusion 71 engage with each other (see FIG. 7). Further, when the hook arm 66 passes through the notch 36 of the rib 35 while being urged to rotate toward the first position, the upper engaging portion 39 and the projection 71 are prevented from being caught, and the opening / closing door 5 The hook arm 66 can smoothly pass through the notch 36 when opening and closing.

The operation of the engagement mechanism 28 will be described. As shown in FIG. 7, when the opening / closing door 5 is opened, as described above, when the operating member 63 is operated and the engagement state of the lock mechanism 26 is released, the hook arm 66 is in the vicinity of the second position. In the state of, the lower door 17 is slightly rotated in the opening direction by the elastic restoring force of the packing 18, and the upper engaging portion 39 and the protrusion 71 are engaged with each other. In this state, the lock mechanism 26 is released, but the opening / closing door 5 is not opened by the engagement mechanism 28, and
The packing 18 maintains a sealed state between the opening / closing door 5 and the front surface 31 of the cleaning chamber 3. Thereafter, as shown in FIG. 8, when the operation of pushing the operation member 63 is stopped, the hook arm 6 is pulled by the restoring force of the tension spring 73 and the weight of the hook arm 66.
6 rotates toward the first position, and the upper engaging portion 39 and the protrusion 71
When the lower door 17 is further rotated in the opening direction by the elastic restoring force of the packing 18,
The hook arm 66 moves forward. Thereby, the opening / closing door 5 can be opened without the engaging mechanism 28 returning to the engaged state. In this way, the packing 18 and the tension spring 73 described above function as a release mechanism that releases the engagement of the engagement mechanism 28 in conjunction with the stop of the operation of the operation member 63 so that the opening / closing door 5 is opened.

The operation of opening the lower door 17 will be described.

When the operating member 63 is operated, as described above, the cleaning operation is stopped and the maintenance of the closed state by the lock mechanism 26 is released. While the operation member 63 is being operated, the blocking member 76 prevents the handle 25 from operating, and
The engagement mechanism 28 keeps the open / close door 5 closed. In this way, the opening and closing door 5 is prevented from being opened at the same time when the operation member 63 is operated. As a result, there is no possibility of the above-mentioned water splash.

After that, when the operation of the operation member 63 is stopped,
The blocking means is separated from the handle 25 so that the handle 25 can be operated, and the engagement state of the engagement mechanism 28 is released. As a result, the opening / closing door 5 can be opened. Since a sufficient time difference can be secured between the operation of the operation member 63 and the opening of the opening / closing door 5 after the operation of the operation member 63 is operated in this manner, water is temporarily sprayed by the coasting operation of the cleaning pump 10 or the like. Even so, the momentum of the water is sufficiently weakened, so that there is no risk of the water splashing when the opening / closing door 5 is opened.

Further, in the present dishwasher, as shown in FIG. 9, the dish basket 4 can be pulled out from the washing chamber 3 and placed on the back surface 58 of the lower door 17 and placed. That is, a mounting portion 40 on which the tableware basket 4 is mounted is formed on the inner side surface of the cleaning chamber 3. The mounting portion 40 extends in the cleaning chamber 3 substantially horizontally in the front-rear direction and is formed from the front end portion to the rear end portion of the cleaning chamber 3. Further, on the back surface 58 of the lower door 17, there is formed a placing portion 81 on which the tableware basket 4 can be placed when it is pulled out. The mounting portion 81 of the lower door 17 is
The left and right sides of the rear surface 58 of the lower door 17 extend from the vicinity of the front end in the open state to the rear end, and the rear end extends from the lower rotary shaft 22.
It is provided up to the position behind. The rear end portion of the mounting portion 81 of the lower door 17 is located immediately before the front end portion of the mounting portion 40 of the cleaning chamber 3 and has substantially the same height. As a result, the placing portion 40 and the lower door 17 of the cleaning chamber 3
The placing portion 81 of the above constitutes a passage that is continuously connected, and the tableware basket 4 can be moved smoothly.

A stopper 82 is provided on the mounting portion 81 of the lower door 17 for restricting the mounting position when the tableware basket 4 is pulled out to the front so that the dishwasher does not fall when the tableware basket 4 is mounted. Is provided. The stopper 82 is formed so as to abut on the wheel 29 and stop the forward movement of the tableware basket 4 so as to project upward from the placing portion 81.
In the stopper 82, the center position in the front-rear direction of the tableware basket 4 at the placement position regulated by the stopper 82 is the front surface 31 of the cleaning chamber 3.
The mounting position is regulated so as to be rearward of the lower rotary shaft 22 and further rearward of the frontmost leg 41 provided at the bottom of the cabinet 2 of the dishwasher 1.

The tableware basket 4 is formed in a box shape having an open upper side, and each surface of the box is formed in a lattice shape so that washing water can be sprayed on the tableware held inside. ing. Tableware can be stably held in a predetermined posture in the box.

Wheels 29 are provided at the bottom of the tableware basket 4 as support members for movably supporting the wheels.
The wheels 29 are arranged on the left and right sides and are arranged along the front-rear direction.
It is provided at the location. The respective positions of the wheel 29 along the front-rear direction are spaced apart from each other by opening a predetermined length set as follows. That is, the distances L1 and L2 of the wheels 29 are set so that the tableware basket 4 can be stably supported in a state where the tableware basket 4 straddles both the mounting portions 40 and 81 of the cleaning chamber 3 and the lower door 17. Has been done. For example, when the frontmost wheel 29 is located on the mounting portion 81 of the lower door 17 which is behind the lower rotary shaft 22, there are two or more rear wheels 29 in the cleaning chamber 3. The tableware baskets 4 are arranged at positions and at intervals so that they can be stably supported. Distance L1 between each wheel 29 between the foremost part and the middle part
Is longer than the distance L3 in the front-rear direction between the lower rotary shaft 22 and the front end of the mounting portion 40 of the cleaning chamber 3. The distance L2 between the middle and rear wheels 29 is such that only the wheels 29, that is, the frontmost wheel 29 is not in contact with the placing portion or the like, so that the tableware basket 4 can be stably supported, It is approximately half or more of the dimension L4 of the tableware basket 4 in the front-rear direction.

Normally, the tableware basket 4 is attached to and detached from the tableware basket 4 in a state in which the tableware basket 4 is pulled out to the frontmost position above the lower door 17. At this time, since the space above the tableware basket 4, particularly the front half or more of the tableware basket 4 is open, it is easy to attach and remove the tableware to the tableware basket 4 and easily attach and detach the large-diameter plate. it can.

Further, to remove the tableware basket 4, the front half of the tableware basket 4 is pulled out from the cleaning chamber 3 to the lower door 17, and the table 29 is moved until the wheels 29 hit the stopper 82. It is placed on the placing portion 81 of. At this time,
Since the vicinity of the center of gravity of the tableware basket 4 can be grasped, it becomes easy to lift. Further, since the tableware basket 4 can be pulled out of the cleaning room 3, it is not necessary to secure a space in the cleaning room 3 for putting the tableware 4 inside the cleaning room 3 into the cleaning room 3 as a result, so that the cleaning room 3 can be removed. 3 can be miniaturized and space can be saved.

To attach the tableware basket 4, the tableware basket 4
The front half of the tableware basket 4 is placed on the lower door 17 with the rear part inserted in the opening 30. After that, the tableware basket 4 is pushed backward to be housed in the washing room 3. At this time, the tableware basket 4 which is short in the moving direction corresponding to the thin washing chamber 3 tends to be pushed obliquely with respect to the moving direction. Can be accommodated smoothly.

As described above, in the present embodiment, since the opening / closing door 5 is divided into the small-sized upper door 16 and the lower door 17, the space for opening / closing the entire opening / closing door 5 is provided with the opening covering the same size. Compared to the one-plate open / close door that is dynamically supported,
Can be made smaller.

Moreover, since the upper door 16 and the lower door 17 are closed next to each other, the opening / closing door 5 as a whole can cover the opening 30 having substantially the same size as that of the conventional opening / closing door which is not separated.

Therefore, it is possible to realize the dishwasher 1 which can be installed on the sink without any trouble. For example, when the dishwasher 1 is installed sideways on the upper surface which is a side of the sink of the sink, when the opening / closing door 5 is opened, the lower door 17 collides with the faucet of the sink or the faucet, and the upper door 16 Can be prevented from colliding with the closet provided above the sink.

Moreover, the tableware basket 4 is moved from the washing chamber 3 to the lower door 1
Since the tableware basket can be pulled out to 7, the tableware basket can be easily taken in and out compared with a state in which the tableware basket is left inside the washing room.
For example, as a result of being able to approach the tableware basket 4 and opening the periphery of the tableware basket 4, it becomes easier to attach and remove the tableware to and from the tableware basket 4. Further, the tableware basket 4 can be easily lifted by grasping near the center of gravity, and the moving distance of the tableware basket 4 between the cleaning chamber 3 and the lower door 17 is larger than that of the conventional single-plate open / close door 5. Therefore, it is easy to attach and remove the tableware basket 4 especially when tableware and the like are held in the tableware basket 4 and all of them are heavy.

Since a part of the tableware basket 4 is placed on the lower door 17, it is preferable to make the lower door 17 compact and to secure a sufficient amount of tableware held in the tableware basket 4 for home use.

Further, by pulling out the tableware basket 4 onto the lower door 17, it is possible to shake it to drop water drops adhering to the tableware and the tableware basket 4 to drain water, and the lower door 17 at this time. Since it can catch falling water drops, it does not wet the surroundings.

Further, by placing a part of the dish basket 4 on the lower door 17, the dishwasher can be prevented from tipping over. In particular, in the dishwasher 1 having the thin washing room 3, it is expected that the dishwasher 1 will easily fall when the dish basket 4 is placed on the opening / closing door 5, but it is difficult to fall as described above. ,no problem. That is, as described above, the small-sized lower door 17 can reduce the moment that acts to cause the tableware basket 4 to fall when it is placed thereon. further,
Even if part of the tableware basket 4 is pulled out to the lower door 17, the remaining part of the tableware basket 4 is in the washing room 3, so the tableware basket 4
This is because the above-mentioned moment can be reduced as compared with the case where the whole is mounted on the lower door 17.

Further, in the present dishwasher 1, as shown in FIG. 1, since the washing pump 10 is arranged near the rear of the dishwasher 1, it is possible to prevent the dishwasher 1 from tipping over. For example, the position of the central portion of the cleaning pump 10 is arranged behind the substantially central position of the cabinet 2 in the front-rear direction. The position of the motor 13 in the front-rear direction is also the same as that of the cleaning pump 10. Since the washing pump 10 and the motor 13 are usually heavy, they are arranged rearward so that a moment in the direction opposite to the above-described tipping direction (acting in the clockwise direction in FIG. 1 centering on the bottom of the frontmost leg 41). Moment) can be increased. Moreover, the cleaning pump 10 and the motor 13 are arranged at a lower position below the cleaning chamber 3. Therefore, even when the tableware basket 4 is placed on the lower door 17, it is possible to realize the stable dishwasher 1 which is hard to fall down.

Further, since part of the tableware basket 4 is left in the cleaning chamber 3, the tableware basket 4 can be moved smoothly. In particular, it is preferable to smoothly move the short tableware basket 4 in the pull-out direction corresponding to the thin cleaning chamber 3.

Further, in the thin washing chamber 3 having a planar shape elongated in one direction, for example, it is possible to realize the dishwasher 1 which can be installed even when the width of the space on the side of the sink is narrow when viewed from the front. .

The cover member 57 of the lower door 17 allows the upper door 16 to be opened by operating the handle 24 of the upper door 16 after opening the lower door 17. In this way, the lower door 17 is surely opened before the upper door 16, so that the lower door 17 can receive the falling water droplets, and as a result, water wetting can be suppressed.

When the upper door 16 is opened, the frontmost portion of the upper door 16 is positioned rearward of the uppermost front portion of the lower door 17 so that the upper rotary shaft 20 is lower than the lower rotary shaft 22. Placed behind. As a result, the lower door 17 is replaced by the upper door 16
It is possible to reliably receive the water droplets falling from the above, and it is possible to further suppress the above water wetting. Moreover, the lower door 17 can be made smaller than the upper door 16 while obtaining this effect. In addition,
In order to obtain the effect of suppressing water wetting, the lower door 17 may have substantially the same size as the upper door 16.

Further, since the lower door 17 is smaller than the upper door 16, the lower door 17 and the faucet can be more difficult to collide with each other when the dishwasher 1 is installed laterally on the side of the sink as described above.

Further, the above-mentioned blocking member 76 prevents the lower door 17 of the opening / closing door 5 from being opened at the same time when the operating member 63 is operated, and after securing a sufficient time difference after operating the operating member 63. Since the opening / closing door 5 is designed to be opened, even if the cleaning pump 10 is inertially driven, there is no possibility that water will splash due to this.

Since the above-mentioned engagement mechanism 28 is provided,
Even if the maintenance of the closed state by the lock mechanism 26 is released after the operation member 63 is operated, the opening / closing door 5 is not temporarily opened. As a result, the opening / closing door 5 is prevented from being opened at the same time as the operation of the operating member 63, and the opening / closing door 5 is opened after a sufficient time difference has been secured after operating the operating member 63. There is no risk of water splashing.

Since the engagement mechanism 28 is provided,
Even if the lower door 17 of the opening / closing door 5 is opened without using the handle 25, water splash can be reliably prevented.

Further, the wheels 29 as support members for the tableware basket 4 are arranged at three or more positions on one side, which are separated from each other, as described above. If there are support members at two positions on one side, the tableware basket 4 can be supported. Therefore, for example, when the tableware basket 4 is pulled out, the tableware basket 4 is stabilized in the cleaning chamber 3 by the support members at the two rear positions. The supporting member at the foremost portion can be floated while supporting it, and can be smoothly placed on the lower door 17. As a result, it is possible to prevent the lower door 17 from being flipped up by the weight of the tableware basket 4.

Here, the support member includes a wheel 29 rotatably supported and a sled 83 having a lower surface slidably fixed as shown in FIG. This sled 83
The shape of is not limited, in addition to the plate-shaped member extending in the front-rear direction,
A member having a leg 41 shape with a lower portion having an R shape may be used, and in short, a member that supports at a plurality of positions which are the positions of the wheels 29 described above may be included, and the members at these plurality of positions are separately formed. Alternatively, the members at a plurality of positions on one side may be integrally formed (this integrated sled 8
3 is shown in FIG. ). Also, the sled 83 and the wheel 29
You may use together with. The wheels 29 may be provided at at least three positions on one side. The positions of the supporting members in the front-rear direction may be different on the left and right sides or may be the same.

Especially when the lower door 17 is small and light,
The tableware basket 4 has a lower door 17 behind the lower rotation shaft 22.
The lower door 17 easily jumps up when the lower door 17 leans on the rear end of the mounting portion 81. In order to prevent this jumping up, the above-mentioned arrangement of the supporting member is preferable.

When the upper door 16 of the opening / closing door 5 is rotated, the height of the highest portion of the upper door 16 (see the dimension E1 in FIG. 3D) is set to 660 mm or less. This can prevent the opening / closing door 5 from hitting the closet when opening / closing in a standard home use state. Furthermore, the distance (see dimension E2 in FIG. 3D) measured along the front-rear direction between the front edge of the lower door 17 and the front surface of the cabinet 2 in the opened state is 130 mm or less. This can prevent the lower door 17 and the faucet from colliding with each other, for example, when the dishwasher is installed laterally along the sink on the side of a standard domestic sink.
Moreover, it is possible to prevent the use of the sink from getting in the way.

The opening 30 is formed only on the front surface 31 of the cleaning chamber 3. This eliminates the need to leave the upper surface of the cleaning chamber 3 open and closed for opening and closing the opening and closing door 5,
The dishwasher 1 can be mounted on the upper surface of the cabinet 2 and is easy to use. Further, since the opening / closing door 5 for the opening 30 can be made smaller in size than the opening / closing door for the opening on the upper surface or the side surface, the opening / closing space of the opening / closing door 5 can be reduced. Here, the front surface 31 of the cleaning chamber 3 includes the front surface of the outer shape of the cleaning chamber.

The front surface 31 of the cleaning chamber 3 is inclined upward. As a result, the inside of the cleaning chamber 3 is opened wider by the opening 30, so that the dishes can be more easily taken in and out.

The front-rear dimension of the lower door 17 in the open state is shorter than the front-rear dimension of the cabinet 2.
In particular, it is shorter than the front-back dimension of the tableware basket 4. As a result, the front half of the tableware basket 4 is placed on the lower door 17 and the rear half of the dish basket 4 is placed in the cleaning chamber 3. Therefore, the center of gravity of the dish basket 4 when pulled out can be set in the vicinity of the front end of the washing chamber 3 in the front-rear direction, so that the dishwasher 1 can be more difficult to tip over.

Further, the stopper 82 of the lower door 17 can surely prevent the dish basket 4 from coming to the front too much with a simple structure, so that the dishwasher 1 can be prevented from falling.

The dishwasher 1 of the above-mentioned embodiment is
Although it has a thin cleaning chamber 3, it is not limited to this.
For example, the cleaning chamber may have a substantially square planar shape.

Besides, various design changes can be made without departing from the spirit of the present invention.
