Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher used at home.

[0002]

2. Description of the Related Art Conventionally, a dishwasher of this type has a structure shown in FIG.
11 is generally used, in which items to be cleaned such as dishes are stored in a cleaning tank, the opening 2 provided in the main body 1 is closed by a door body 3, and then a cleaning pump is used. By injecting, the cleaning and rinsing steps of the object to be cleaned have been performed. In FIG. 10, the opening 2 is provided on the front surface of the main body 1, and the door 3 is rotated downward to open the opening 2. In FIG. 11, the opening 2 is provided on the upper surface, and the door 3 is opened. Was configured to rotate upward and open.

[0003]

However, as shown in FIG.
In the conventional dishwasher shown in Fig. 1, since one door body 3 is opened downward, a large space is required to rotate the door body 3, and the total floor area of the main body 1 and the area of the door body 3 is required. However, there is a problem in that the installation property of the dishwasher becomes poor. Further, since the front projection of the door body 3 is long, there is a problem that it is difficult to take in and out the object to be cleaned from the front. On the other hand, in the example of FIG. 11, since it is opened upward, almost no installation area other than the dimensions of the main body is required, but since the opening 2 is large, the floor area of the main body itself becomes large, and as a result, Installation will be poor. Further, since the opening is large upward, the maximum height due to the opening and closing of the door becomes high, and in some cases this device cannot be installed due to the height limitation of the installation place.

Recently, in order to improve the installability in a small kitchen in Japan, the floor area of the device itself has been reduced to improve the installability.
In order to secure the internal capacity, it is necessary to increase the height of the main body 1, and depending on the opening / closing method of the door body 3, it is often impossible to install the door body 3 due to the height limitation. That is, it is an object to provide a device having a small installation area and a low height.

Further, as a device for opening and closing a high-height door body, there is one disclosed in Japanese Patent Application Laid-Open No. 50-26356 shown in FIG. It is configured to open and close in any direction. The length of each door body 3a, 3b is shortened, and the installation area and installation height can be kept low.

The door body 3b which opens upward is the door body 3
It is designed to rotate about the upper end of b as a fulcrum, and regardless of the division of the door body, the protruding height to the upper side becomes large,
Due to the limited installation height, there is a high possibility that it cannot be installed.

In order to reduce the height at the time of opening,
It is necessary to stop the door body 3b while projecting it forward from the top of the main body, and when this device is installed on the top surface of the sink, the door body 3b in this open position is slightly below eye level. Therefore, there is a problem that it is difficult to check the inside of the cleaning tank 2 and it is difficult to take in and out the object to be cleaned, and contact with the face or the head may lead to danger.

Despite the fact that the penetration rate is 50% or more in Europe and the United States, the main reason why the penetration rate is as low as 10% or less in Japan is that the kitchen space is smaller than in Europe and the United States. However, there are many cases where it cannot be installed. Therefore, in order to provide abundance to a large number of consumers, it is necessary to provide a device that is as compact as possible and has excellent installability.

[0009]

In order to solve the above-mentioned problems, the present invention provides a main body, a cleaning tank provided in the main body, an opening provided with a front surface of the cleaning tank as a main surface, and the opening. A door body for closing the portion and a support means for movably supporting the door body in the space above the main body are provided, and the support means is provided with a slide portion.

As a result, the maximum height of the opening / closing locus of the door can be reduced and the protruding length of the door in the open state can be reduced in spite of the construction in which the door is opened upward. . Tabletop dishwashers are often installed on worktops such as system kitchens and sinks,
In the upper space, hanging cabinets, draining shelves, etc. are often installed, and the installation height is limited. In the dishwasher of the present invention, since the height required for installation can be reduced,
The possibility that this dishwasher can be installed will increase, and it will be possible to answer the request that you cannot install it even if you want to install it.

Further, since the front projection of the door body in the opened state is small, it is easy to check the inside of the cleaning tank,
It is possible to provide a device in which the object to be cleaned can be easily taken in and out.

[0012]

[0018]

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

(Embodiment 1) FIGS. 1 and 2 are a side view and a sectional view of a dishwasher according to a first embodiment of the present invention, and FIG. 3 is a schematic view of a kitchen apparatus according to the first embodiment.

In FIGS. 1 and 2, there is a cleaning tank 5 provided in the main body 1, and an object 6 to be cleaned such as dishes is set in a cleaning basket 7 and stored in the cleaning tank 5. Water supply valve 8 for supplying cleaning water to the cleaning tank 5, cleaning pump 9 for pressurizing the cleaning water
There is an injection hole 1 in the cleaning nozzle 10 for spraying cleaning water.
A plurality of 1 are provided. Further, in the cleaning tank 5, there are a filter 12 for collecting the leftover food and a heating element 13 for heating,
A temperature sensor 14 for detecting the temperature of the cleaning tank is provided.
In addition, the drainage pump 14a for discharging the cleaning water, and the cleaning tank 5
An air blower 15 for sending air is provided, an air blow path 16 for guiding the air blown by the air blower 15 to the cleaning tank 5, and an exhaust port 17 for discharging the exhaust air are provided.

A door body 18 for closing the opening 2 of the cleaning tank 5 is provided, and a support arm fixed to the door body 18 as a support means 19 for movably supporting the door body 18 in the space above the main body 1. 20 and rotation fulcrum 21 are installed. The rotation fulcrum 21 is installed at a position away from the door body 18, and the rotation angle associated with opening and closing is about 75 °. Further, the front surface of the main body 1 and the door body 18 are shaped such that the upper portions thereof are inclined rearward, and the maximum height of the opening locus of the door body 18 including the main body 1 is 700 mm or less.

A seal member 22 is arranged between the door 18 and the main body 1, and the seal member 22 is fixed to the main body 1 side. Further, a handle portion 23 for performing a closing operation of the door body 18 is installed, and lock means for locking the door body 18 and the main body 1 at the closed position of the door body 18 and lock detection means for detecting locking of the lock means ( (Both are not shown), and the support means 19 is provided with a tension spring 24 as a biasing means for biasing the door body 18 upward. Further, the washing basket 7 can be pulled out forward with the door 18 open.

Further, FIG. 3 shows a general kitchen apparatus, which is mainly composed of a sink 25 having a sink and a hanging cabinet 26 provided near the ceiling, and a draining shelf 27 etc. below the hanging cabinet. Is provided. Then, the tabletop type dishwasher 28 is most convenient if it is installed on the worktop top surface 29 of the sink 25 as shown in FIG. Here, in the dishwasher 28, the maximum height of the maximum trajectory of the door 18 including the main body 1 is 700 mm or less.

Next, the operation and action will be described. First, the basic operation of the dishwasher will be described. First, 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 added. 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, the cleaning tank 5
The heating element 13 such as a sheathed heater provided inside is energized, and the cleaning process is performed while heating the cleaning water. Also,
The temperature sensor 14 detects the temperature of the cleaning tank 5, and stops supplying electricity to the heating element 13 when the temperature exceeds a predetermined temperature.

When the cleaning process for a predetermined time is completed, the cleaning water containing dirt is discharged outside the machine by the drainage pump 14a, 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 path 16 and is discharged from the exhaust port 17. At this time, the heating element 13 is energized, and the evaporation of water droplets adhering to the object 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.

Further, by installing the rotation fulcrum 21 at a position apart from the door body 18, the door body 18 can be moved into the space above the main body 1. When a rotation fulcrum is installed on the top 30 of the door body as shown in FIG. 1, in order to completely open the door body, the height of the main body 1 and the door body 18 is indicated by A (two-dot chain line) as shown in FIG. The total space is required. Further, in order to reduce the height associated with opening, it is necessary to stop the door body 18 in a state of protruding forward from the top of the main body 1 as shown by B.

As shown in FIG. 3, the table-top type dishwasher is used by mounting it on the top of the sink or on a dedicated stand. In either case, the washing tank 5 is placed diagonally above the washing machine body.
The height to look inside. Therefore, in the state where the door 18 projects forward from the top of the main body, it is difficult to check the inside of the cleaning tank 5, and it becomes difficult to take in and out the object 6 to be cleaned. In addition, contact of the face or the head with the protruding door body 18 may lead to danger or damage to the device.

That is, the installability and the usability are in a conflicting relationship. Therefore, by moving the door body 18 from the top portion 30 toward the space above the main body 1, the door body 18
Since it can be moved to the space above the main body 1 (solid line in FIG. 1) without standing upright from the main body 1, the maximum height of the opening / closing locus of the door body 18 is low, and the protruding length of the door body 18 toward the front in the open state is small. It is possible to reduce the size, and it is possible to achieve both installation and operability.

In order to correspond to a small kitchen in Japan, a thin and tall type dishwasher has become mainstream. With this shape, the opening 2 on the front of the main body has a larger opening. It is the most advantageous because it can be taken. Then, by moving the 18 door body provided with the front opening 2 to the space above the main body 1, the floor area of the apparatus is small and the installation height is small, so that there is no possibility that this dishwasher can be installed. It becomes expensive and can answer the request that you cannot install it even if you want to install it.

If the one end side of the door body 18 is pivotally supported as shown in FIG. 1, the seal between the door body 18 and the main body 1 is one side of the shaft portion out of the four sides to be sealed. The other three sides need to have different structures, and the seal structure is complicated in order to completely seal. However, when all the sides of the door 18 are opened and closed away from the main body as in the present embodiment, all the sides can be uniformly sealed and the configuration can be simplified.

The door 18 is not located above the main body 1,
A configuration in which it is moved to the inside of the main body is also conceivable, but in that case, the height is increased by the amount of the cover, and the installation property deteriorates.

A rotation fulcrum 21 associated with the opening and closing of the door body 18
Since the rotation angle is about 75 ° and is suppressed to 90 ° or less, the inner surface 31 of the door body 18 to which water drops, dirt, etc. are attached cannot be seen from the front during the opening / closing process of the door body 18. Since the door body 18 is opened above the main body 1, it will be located near the face of the worker when the door body 18 is opened.
Since the inner surface 31 of 8 cannot be seen, it does not feel uncomfortable.

Further, it is possible to prevent dirt or the like from adhering by the clothes or the like coming into contact with the door body 18. When the front surface is vertical, the inside of the door cannot be seen from the front when the rotation angle is 90 ° or less, and when the front surface is inclined rearward, it is 90 ° -the inclination angle. Since the inner surface 31 is not exposed, the rotation angle needs to be 90 ° or less.

Further, the front surface of the main body 1 has a shape in which an upper portion 32 is inclined rearward, and the door body 18 and the main body 1 are
The angle with the top surface is 90 ° or more (about 120 ° in the figure). A schematic view is shown in FIG. 4. When the front surface is vertical as shown in FIG. 4A, the vicinity of the top of the door body 18 slides laterally while contacting the seal member, but the front surface is When it is inclined, as shown in FIG. 4B, there is no side slip, and the door body moves in the direction away from the seal member 22.

When the door body slides on the seal member 22, the operating force increases and at the same time the seal member 2 moves.
2 may be worn or damaged, which is not desirable. Note that the opening / closing locus of the door body 18 becomes large in order to eliminate skidding. In addition, the same problem occurs when closed. Therefore, by tilting the front upper portion 32 of the main body rearward, even if the simple rotation fulcrum 21 is used, reliable sealing can be performed with a small operating force, and a highly durable sealing structure can be realized.

When the door 18 has a curved surface, the inclination angle is not clear, but the tangent angle of the door top 30 or the angle connecting the upper and lower ends 33, 34 of the door can be substituted.

Although the door body 18 itself is inclined rearward, even if the door body 18 is vertical, the shape of the portion in contact with the door body 18 and the seal member 22 is inclined rearward or arcuate. The same effect can be obtained by using a shape.

Further, the lower end portion 33 of the inner surface of the door is always positioned lower than the upper end portion 34 in the entire opening / closing range of the door body 18, and since the water droplets are always gathered downward, the lower end portion 33 is formed. It is possible to prevent water drops and dirt from gathering on the side and dropping on the top surface of the main body 1. Further, if the water droplets on the door 18 are dropped into the cleaning tank 5, it is possible to prevent the water droplets from falling outside the apparatus. Alternatively, by providing the structure for receiving water drops only on the lower end portion 33 of the door body 18, it is possible to prevent the water drops from falling.

Further, in this embodiment, the maximum height of the opening locus of the door body including the main body of the dishwasher is 700 mm or less, and the dishwasher can be installed in a general kitchen. Assuming a general kitchen set, as shown in FIG. 3, the height of the sink 25 to the top surface 29 is 850 mm,
The standard height of the hanging cabinet 26 is 2350 mm. The height of the hanging cabinet 26 is 500, 700, 900m.
When there is m or the like and only the hanging cabinet 26 is installed above the sink, a shelf with a height of 700 mm is installed in most cases.

In this case, the sink top surface 29 and the hanging cabinet 26
The distance from the lower part of is about 800 mm. Further, in an apartment house or a kitchen set of a relatively small size, as shown in FIG. 3, a draining shelf 27 is often provided at the bottom of the hanging cabinet 26, and generally, a hanging cabinet having a height of 500 mm has a draining shelf of about 300 mm. Yes, the top 29 of the sink and the draining shelf 27
The distance from the lower part of is about 700 mm.

Therefore, the height when the door body 18 is opened is 7
By setting the width to 00 mm or less, the present dishwasher can be installed in a general kitchen regardless of whether it is an individual house or an apartment house. According to our survey results, the height is 7
If it is less than 00 mm, it can be installed in about 75% of existing homes.

When the door 18 can be stopped at a plurality of positions within the openable range, the height is at least 70.
If it can be stopped at a position of 0 mm or less, the above effect can be obtained.

Further, in the present invention, the door body 18 including the main body 1
The maximum height of the open locus was set to 700 mm or less,
When the height is 0 mm or less, it is possible to deal with the case where the installation height of the hanging cabinet 26 is low due to the system having a height of 2300 mm, the construction, etc., the installation possibility increases, and the kitchens of most manufacturers can be accommodated. In this case, according to our survey, it can be installed in the kitchen of about 85% of the existing houses. Furthermore, if the height is 600 mm or less, the dishwasher 43 can be installed even when the hanging cabinet 26 having a height of 900 mm is installed, and can be installed in 95% or more of existing homes.

Although not particularly described, it goes without saying that the minimum height value is equal to or larger than the size of the main body 1.

If the cleaning basket 7 is constructed so that it can be pulled out forward when the door 18 is open, the object 6 to be cleaned can be easily taken in and out of the interior of the cleaning basket 7, and the cleaning basket 7 can be moved forward. Even if the door body 18 is slightly projected, the usability is not impaired.

Since the tension spring 24 urges the door body 18 upward, the weight of the door body 18 is offset, the opening / closing operation force of the door body 18 is reduced, and the operability is improved. Further, the impact force when the door body 18 freely descends due to gravity can be reduced, and the stress applied to the device is reduced, which leads to improvement in durability and downsizing of the device. Moreover, if the biasing force of the tension spring 24 of the door body 18 is balanced, the door body 18 can be stopped at an arbitrary place.

In this example, the number of doors 18 is one, but by dividing the door 18 into a plurality of pieces and shortening the length of one door 18, the installability can be further improved. Although the supporting means is the rotation fulcrum 21, it is not limited to this.
Any structure may be used as long as it can move above the main body.

Further, the present invention relates to the opening / closing structure of the door body 18, and does not limit the cleaning or drying method or structure, the operation mode, or the like. In the embodiment, the example of the dishwasher having the drying function is shown, but the dishwasher not having the drying function, the tableware dryer that only performs the drying, or the other devices such as the storage device may have the door of the present invention. The structure is available. Further, this door configuration is applicable to other devices, and the same applies to other embodiments.

(Second Embodiment) FIG. 5 is a side view of a dishwasher according to a second embodiment of the present invention, in which the same components as those of the first embodiment shown in FIG. 1 are designated by the same reference numerals.

As shown in FIG. 5, the supporting means 19 including the rotation fulcrum 21 and the support arm 20 is provided with a slide portion 35 for moving the rotation fulcrum 21, and further, a guide groove 36 and a guide portion 37 engaging with the guide groove 36. Are installed on the main body 1 and the support arm 20, respectively. Further, the upper surface 38 of the main body has a shape that is inclined forward and backward.

The operation and action in this embodiment will be described. When the door 18 is opened, first, the slide portion 3
5, the rotation fulcrum 21 slides from C to D and then rotates to the point E. At this time, since the guide groove 36 and the guide portion 35 are engaged with each other, the opening / closing operation is uniquely performed.

At the initial stage of this opening operation, the door body 18 moves in a direction substantially perpendicular to the main body 1 along with the movement from C to D. It does not slip in the direction and can be reliably sealed with a small operating force, and high durability can be obtained. Similarly, when the door 18 is closed, the seal can be surely sealed with a small force. Even if the front surface of the main body 1 is not inclined rearward as shown in the figure, the door body 18 can be moved to the space above the main body 1.

Since the door body 18 passes through the space above the main body 1, if the door body is opened while the article is mounted on the upper surface 38 of the main body 1, the article may be dropped, but By inclining the upper surface 38, it is possible to prevent an article from being erroneously placed, and to prevent the article from falling or falling.

Although the structure is inclined forward and backward in the drawing, it is impossible to mount an article such as inclined forward or backward, inclined leftward or rightward, or formed into a curved shape or provided with unevenness. However, the configuration may be unstable when mounted. In addition, it is also effective to specify in text.

(Third Embodiment) FIGS. 6 and 7 are a side view and a sectional view of a dishwasher according to a third embodiment of the present invention. The same components as those of the first embodiment shown in FIG. Is given.

As shown in FIG. 6, in this embodiment, the door body is divided into two parts, that is, a lower door body 39 and an upper door body 40. Two pieces of supporting means 19 for movably supporting the upper door body 40 are provided. The rotating arm 41 is used. The support means for the lower door body 39 is the rotation fulcrum 42. Furthermore, two door bodies 3
The interlocking means 43 for interlocking the opening / closing operation of the doors 9 and 40 is provided.
It is provided in.

To describe the operation and action, the rotating arm 41 supports the upper door 40 so that it can be opened and closed. However, unlike the case of using the rotation fulcrum, the movement locus is not a simple arc, and in the configuration shown in the figure. , The upper door body 40 moves as shown by the alternate long and short dash line. Immediately after opening, the door body 40 moves from the main body 1 in a substantially vertical direction, then moves while turning upward, and finally moves to the state of the solid line in the figure. Since the door body 40 moves in a substantially vertical direction with respect to the seal member 22 provided between the door body 40 and the main body 1, the opening / closing operation force is small, and the seal member 22 is less likely to be worn or damaged. That is, by using the two rotary arms 41, the door 40 can be moved above the main body 1 while achieving a reliable and highly durable seal structure, and the same effect as that of the first embodiment can be obtained.

Further, since the door body is divided into two, and the length of one door body is short, the protruding length of the main body 1 upward and forward is further reduced. In addition, since there is a margin in terms of design, the sealing structure becomes more reliable. Further, in the case of one door body, even if the upper door body 40 projects forward, it can be completely housed in the space above the main body 1 by dividing the upper door body 40 into two or more, and the inside of the cleaning tank 5 Is easier to see,
The object 6 to be cleaned can be easily taken in and out. Alternatively, when the door 40 is not opened to the rear portion of the upper surface of the main body, the rear portion of the upper surface 32 can be used as a storage place.

Further, although the lower door body 39 is constructed so as to rotate downward, since the length of the door body 39 is short, the installation area can be made small and the installation is unlikely to be a hindrance. Further, it is possible to receive water drops and dirt falling from the upper door 40, the cleaning basket 7 that has been drawn out, etc., and prevent them from falling outside the device. Especially, as shown in the figure, the opening / closing locus of the upper door body 40 is changed to the lower door body 39.
If you set it so that it fits behind the tip of the, you can completely prevent drops such as water drops.

Further, when the dishes or the like are stored in the cleaning basket 7, it is possible to prevent the residual juice or the residual food from dropping in front of the opening 2. That is, in the main body 1 which is thin and has a front opening, it is easy to install and convenient to put in and take out, and it is possible to prevent water drops and dirt from falling out of the apparatus.

Further, as shown in FIG. 7, when the cleaning car 7 is constructed so that it can be pulled out forward when the door is open, the object 6 to be cleaned can be easily taken in and out from the inner part of the cleaning car 7. Since the cleaning basket 7 can be pulled out above the lower door body, it is possible to prevent water drops and dirt from falling out of the apparatus when the cleaning basket 7 is pulled out.

Further, interlocking means 43 for interlocking the opening / closing operation of the upper and lower door bodies 39, 40 is provided, and if the handle portion 23 provided on the lower door body 39 is opened to open both door bodies 3,
9 and 40 can be opened and closed with one operation, and the usability of the device is dramatically improved. In addition, the interlocking means 43 includes a door body 39,
Since the opening / closing order of 40 can be uniquely regulated, if the lower door body 39 is opened first and the tip thereof is set to be always positioned in front of the upper door body 40, water droplets or the like can be reliably discharged from the device. It can be prevented from falling. Further, the operator does not need to consider the opening / closing order of the door body.

Specifically, a fulcrum 44 is provided on the opposite side of the rotation fulcrum 42 of the lower door body 39 at a position extending on a substantially straight line, and the fulcrum 45 on the rotating arm 41 and the fulcrum 44 are connected by the interlocking means 43. By connecting, the lower door body 39 can be opened first. Further, even the supporting means 19 of the first embodiment can be interlocked similarly.

Further, since the interlocking means 43 has a link structure, the interlocking operation can be uniquely regulated at the time of opening and closing, so that the interlocking opening / closing operation can be surely performed regardless of the operation of any door body. Further, even when the upper door body 40 is operated, the lower door body 39 moves in conjunction with each other, so that the operated door body does not matter. The interlocking means 43 is not limited to the link structure, and may be connected by a wire, a gear, a belt,
Similar effects can be obtained even with other configurations such as interlocking with a chain or the like.

Further, with the configuration shown in the figure, the connecting means 43
Does not stick out to the outside of the body, and there is no danger of pinching your fingers between the links. Also, a good appearance is obtained.

Further, in FIG. 6, the supporting means 19 such as the rotating arm 41 is shown installed on the side surface of the main body 1 for the sake of clarity, but as shown in FIG.
Can be housed inside. In the closed state of the door body 40,
Since the supporting means 19 is not exposed to the outside, a good appearance can be obtained, and there is no danger of a finger being caught during starting.

Also, during the opening / closing operation, even if the door 40 is operated while holding the hand of the main body 1, there is no danger of pinching a finger or the like.
Further, the sealing member 22 is installed inside the supporting means 19 so that the supporting means 19 is completely sealed from the inside of the cleaning tank 5, and even if it is made of metal, rust and corrosion are prevented. Durability is improved.

Further, in order to secure the strength of the side wall 46 and reduce the width, it is preferable that the member coming in and out of the main body is thin so that the connecting means 43 does not stick out to the outside of the main body 1. In that case, since the rotating arm 41 is the only member that goes in and out of the main body 1, it is possible to reduce the size in the width direction. The same applies to the other examples.

Although the example in which the interlocking means 43 is provided is shown in this embodiment, the opening 2 can be opened even if the upper and lower door bodies 39 and 40 can be opened separately without using the interlocking means.
Can be opened.

Since the inter-door seal member 50 is installed at the position where the doors 39 and 40 are divided, the length of the door can be minimized, so that the dividing surface can be surely prevented without impairing the installation property. Can be sealed. Since the divided position of the door body is between the free ends and is easily bent by thermal deformation, pressing, etc., reliable sealing becomes difficult, but by using the inter-door seal member 50 having elasticity that can absorb this bending, Door body 3
The sealing property between 9 and 40 can be maintained and water leakage can be prevented.

Further, in this embodiment, the opening / closing order of the door bodies 39 and 40 is determined, and the lower door body 3 is opened at the time of opening.
After opening 9, the upper door 40 is opened. The door-to-door seal member 50 is installed so as to be adapted to the opening and closing order. Since the door-to-door seal member 50 can be pressurized in a substantially vertical direction, it does not damage the door-to-door seal member 50 and is small in size. It is possible to reliably seal with the operating force. Further, since the door body 39 that opens downward is opened first, it is possible to receive the water droplets that drop with the opening of the upper door body 40, and prevent the water droplets from falling outside the device.

Although not shown, if locking means for locking the door bodies 39, 40 and the main body 1 at the closed position of the door body is provided in the vicinity of the divided position of the door body, The vicinity is a position where the movement distance associated with opening and closing is the largest, and the door can be locked with the smallest force. Also, the door body 3
Even if 9, 40 are engaged with each other, the door body and the main body 1 can be locked.
All you have to do is lock it in place.

Although the door body is divided into two, one door body 40 may be used and the rotary arm 41 can be rotated upward.

Further, although the example of the desk-top type having the front opening 2 is shown, the door of the present invention can be used even if it is a built-in type or the main opening 2 is provided above. Can be applied.

(Fourth Embodiment) FIG. 9 is a side view of a fourth embodiment of a dishwasher according to the present invention. The same components as those of the first or third embodiment shown in FIGS. 1 and 6 have the same reference numerals. Is given.

As shown in FIG. 9, the supporting means is composed of two slide portions 35, and the slide portion 35 is composed of a slide groove 47 and an engaging portion 48 that engages with the slide groove 47. Further, the opening 21 is configured to include a part of the upper surface 49 of the cleaning tank.

By using the slide portion 35, the door body 40
The movement trajectory of can be set arbitrarily, the movement direction immediately after opening,
The amount of protrusion of the door 40 from the main body 1 in the open state can be set, and an optimum state can be obtained.

Further, by forming a part of the upper surface 49 of the cleaning tank 5 as the opening 2 as shown in the figure, a wider and easier-to-use opening 2 can be obtained and the sealing portion can be inclined rearward more easily. Therefore, sealing can be easily performed. In addition, a part of the side surface can be used as an opening, so that a device that can be easily taken in and out from the side can be provided.

[0081]

As described above, according to the present invention, the door body is opened upward by providing the support means for movably supporting the door body in the space above the main body. The maximum height of the opening / closing locus of the door body can be reduced, and the protruding length of the door body in the open state can be reduced. Since the installation floor area is small and the height can be kept low,
The possibility that this dishwasher can be installed will increase, and it will be possible to answer the request that you cannot install it even if you want to install it.
Further, since the frontward protruding length of the door body in the opened state is small, it is possible to provide a device in which the inside of the cleaning tank can be easily checked and an object to be cleaned can be easily taken in and out.

Further, by providing the support means with the slide portion, the door body can be moved in the direction away from the main body in the initial stage of the opening operation regardless of any structure such as the rotation fulcrum, and the door body and the main body can be moved. Can be easily and surely sealed. Further, the entire opening / closing locus of the door body can be configured by the slide portion, and the opening / closing locus can be freely set.
