BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention includes a cleaning tank in which a front surface is opened and a storage basket is put in and out, and a door for opening and closing a front opening portion of the cleaning tank is provided in the front surface of the main body. For example, it relates to a washing machine such as a tabletop dishwasher.

[0002]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention Recently, in a washing machine, for example, a so-called table-type dishwasher installed on a worktop (top plate) of a system kitchen, the length dimension in the front-back direction is about 25 to 40 cm. A thin type has been provided in an attempt to save installation space. As shown in FIG. 14, this is a mechanism for providing a washing tank 2 in a main body 1 having a thin rectangular box shape in the front-rear direction, and for washing and drying the dishes stored in the washing tank 2. (Not shown).

A door 3 for opening and closing the front opening of the cleaning tank 2 is provided on the front surface of the main body 1. The door 3 is pivotally supported by the main body 1 at a lower portion thereof, and is opened forward in a substantially horizontal state. And the cleaning tank 2
A tableware storage basket supporting the tableware is housed therein so that it can be taken in and out. With the door 3 opened, the tableware storage basket can be pulled out forward to take in and out the tableware. You can do it. An operation panel 4 is provided on the front surface of the main body 1 below the door 3. Further, the outer bottom surface of the main body 1 is provided with legs (not shown) located at the four corners, and the legs are mounted on the installation surface.

However, in the above structure, when the door 3 is opened and the tableware storage basket is pulled out, the center of gravity may move to the front side and become unstable. Therefore, the main body 1 is particularly thin. Then, it is necessary to have a structure that prevents the vehicle from falling forward. Therefore, conventionally, the main body 1 is attached to the outer bottom portion of the main body 1.
There is provided an auxiliary leg 5 which extends forward and is prevented from falling forward. This auxiliary leg 5 is separately attached as an accessory, or provided on the bottom of the main body 1 so as to be able to be taken in and out by sliding.
After loosening the screw and pulling it out, the screw is tightened and fixed in the pulling position.

However, the auxiliary leg 5 which is a separate body like this
The configuration having the following has the following drawbacks. That is, the auxiliary leg 5 has a comparatively large forward protrusion length (for example, 150 mm), so that the main body of the auxiliary leg 5 can be installed even if the depth of the auxiliary leg 5 is limited, for example, on the bay window of the kitchen or on the facing counter. In some cases, the auxiliary leg 5 cannot be installed because the auxiliary leg 5 cannot be installed even if the device 1 itself can be installed. In this case, since the main body 1 itself can be installed by the legs at the bottom thereof, there is a risk that the auxiliary leg 5 will not be in contact with the installation surface and will not be used sufficiently, or the auxiliary leg 5 may be used.
May be overlooked or installed without noticing the existence of the auxiliary leg 5. In addition, 1 near the right end of the main body 1
Since only the auxiliary leg 5 is provided for the book, the installation state tends to be unstable even if the book can be installed in a normal state.

Although not shown, the dimension in the front-rear direction is 40.
There is a standard size of ~ 50 cm that has a structure in which a weight is provided at the rear part of the main body.Furthermore, in the floor-standing type dishwasher, the auxiliary leg moves forward in conjunction with the opening of the door. There was also a moveable one. However,
In the former case where the weight is provided, there is a drawback that the size of the main body is increased and the weight becomes unnecessarily large. On the other hand, in the latter one having a movable auxiliary leg, when the auxiliary leg is installed in the vicinity of the sink, there is a possibility that the protruding auxiliary leg may fall on the sink (space portion) and the fall prevention effect may not be exerted. Further, when the auxiliary leg comes out, there is also a problem that the kitchen utensil or the like placed on the worktop is pushed away.

The present invention has been made in view of the above circumstances, and an object thereof is to equip a front surface of a main body so that a door can be opened and closed, and to be installed stably without using a separate auxiliary leg. The purpose is to provide a washing machine that can.

[0008]

According to a first aspect of the present invention, there is provided a washing machine which is provided with a washing tank in which a front surface is opened and a storage basket is put in and taken out, and the washing tank is provided on the front surface of the main body. In the one provided with a door that opens and closes the front opening, a protrusion is provided at the lower portion of the main body, the protrusion protruding forward from the front of the door, and the protrusion contacts the installation surface on which the main body is installed. It is characterized in that a grounding portion for supporting the main body is provided.

The stability of this type of washing machine when the door is opened and the storage car is pulled out is the stability between the fulcrum on the front side of the main body (the grounding position on the installation surface) and the position of the center of gravity that fluctuates forward. Determined by the relationship, the more stable the fulcrum is in front of the center of gravity, the more stable According to the above configuration, since the grounding portion is provided in the protruding portion provided on the lower portion of the main body so as to protrude forward of the front surface of the door, the position supporting the main body on the front side can be brought forward. As a result, it is excellent in the forward fall prevention effect.

At this time, since the projecting portion and thus the grounding portion are provided in the lower portion of the main body in advance, a separate member is not required, and when the main body is installed, an auxiliary leg of the separate member is attached or it is pulled out forward and fixed. If the grounding part does not touch the installation surface, it is immediately understood that it is not suitable to install it in that position, so it is possible to prevent it from being installed in a position with poor stability. can do.

It is also possible to provide an inclined surface portion which descends and is inclined forward on the upper surface portion of the projecting portion, and to provide an operation panel on the inclined surface portion (the invention of claim 2). According to this, since the operation panel is provided on the lower front surface of the main body,
Even if the user's eyes are higher than the operation panel and the user operates from above, the operation panel is arranged in an inclined shape that descends forward, so that the operation panel The visibility is good and the operation is easy.

In this case, the projecting portion can be provided so as to project forward from the front plate provided at the lower portion of the door on the front surface of the main body (invention of claim 3). The configuration can be simplified. Alternatively, the protrusion may be provided on the outer bottom surface of the main body (claim 4).
Invention), and thereby, the strength of the protrusion can be improved. Furthermore, a gutter-shaped water receiving recess may be provided on the upper surface of the protrusion (the invention of claim 5), whereby the water receiving recess receives drops of water or the like dripping from the door or the front opening. It is possible to prevent it from falling onto the installation surface and getting wet.

In this case, the protrusion may be a long one extending over substantially the entire left-right direction of the main body.
It may be provided at both left and right end portions of the main body (the invention of claim 6). According to this, except the left and right end portions of the front surface of the main body, it is possible to make the shape retracted rearward of the protruding portion, so that the retracted portion can be widely used. The sink can be widely used by installing the embedded part so that the sink covers the sink.

It is effective if the grounding portion is composed of leg portions provided at least at two positions on the left and right ends of the main body on the lower surface of the projecting portion (claim 7). invention). With this, when the leg portion is not in contact with the installation surface, the fact can be easily understood, so that the leg portion can be surely installed in a state of being in contact with the installation surface.

In this case, when the height of the leg portion is adjustable, the protrusion is relatively large in the vertical direction because the adjusting mechanism is incorporated. In contrast,
By forming the leg portion provided on the lower surface of the protrusion as a fixed leg whose height cannot be adjusted, the protrusion can be made thin (invention of claim 8).

When the leg is a fixed leg whose height cannot be adjusted, a flat contact portion is formed around the fixed leg on the lower surface of the protruding portion, and an annular or cap-shaped spacer is provided on the fixed leg. The height can be adjusted by fitting it around the contact part until it comes into contact with the contact part (invention of claim 9), which allows the height to be adjusted with a simple structure. Even on an inferior installation surface, the main body can be installed horizontally. At this time, the abutting portion may be composed of a plurality of ribs (invention of claim 10), whereby a flat abutting portion can be easily formed even when the protruding portion is made of synthetic resin. Can be formed.

According to an eleventh aspect of the present invention, there is provided a washing machine in which a main body is provided with a cleaning tank having a front surface opened and a storage basket is taken in and out, and a front opening of the cleaning tank is opened and closed on the front surface of the main body. In the one provided with a door, a locking portion is provided on a side surface or a back surface of the main body, and the main body is
One of the features is that one end is locked to the locking portion, and the other end is fixed by a substantially C-shaped fixture that is locked to the installation surface or an auxiliary installation plate arranged on the installation surface.

According to this, the main body is fixed to the installation surface or the auxiliary installation plate arranged on the installation surface by the C-shaped fixture, so that the main body is prevented from tipping forward. It is possible to install stably without using auxiliary legs. At this time, since the C-shaped fixing tool does not project forward long like a separate auxiliary leg,
The installation space can be reduced. At this time, by using the auxiliary installation plate, the installation can be performed even when a part of the main body is located off (floating) from the installation surface.

Further, in this case, if the locking portion is provided between the leg portions provided on the bottom portion of the main body (invention of claim 12), the holding is biased. Instead, the whole can be stably held, so that it can be fixed by one fixing tool.

Further, when the auxiliary installation plate is used, a recess may be formed in a side edge portion of the auxiliary installation plate to which the other end side of the fixture is locked (claim 1).
Invention of 3). According to this, since the other end side of the fixture does not project downward from the auxiliary installation plate, the auxiliary installation plate can be arranged on the installation surface without rattling. If the auxiliary installation plate is configured to have a weight that functions as a weight for preventing the body from falling (invention of claim 14), it is possible to prevent not only the front side of the main body but also the falling in any direction. It can be installed more stably.

(2) Second to Fourth Embodiments Next, second to fourth embodiments of the present invention will be described.
It should be noted that these second to fourth embodiments can be said to be so-called modifications of the first embodiment, and therefore, the same parts as those of the first embodiment are designated by the same reference numerals. Detailed description is omitted, and only different points will be described below.

FIG. 3 shows the external structure of the main body 31 of the dishwasher which is the washing machine according to the second embodiment of the present invention.
This embodiment differs from the first embodiment in that the main body 31
The point is that the height dimension of the protrusion 32 provided in the lower part of the is reduced. In this case, the upper surface of the projecting portion 32 is the inclined surface portion 33 which is inclined downward toward the front. The inclination degree of the inclined surface portion 33 when viewed from the front is the inclined surface portion 21 of the first embodiment. Is bigger than The inclined surface portion 33 is provided with only the key operation portion 22, and the display portion 23 is provided in a vertically rising portion above the display portion 23.

According to this, when the door 16 is opened, the water receiving recess 39 can receive water droplets or the like dripping from the lower end portion of the door 16 or the front opening 12 of the main body 37, and water or the like falls on the installation surface A. It is possible to prevent it from getting wet.

(3) Fifth and Sixth Embodiments Next, referring to FIG. 6 to FIG. 9, the fifth embodiment of the present invention (claims 1, 3, 4, 6, 7, 8, (Corresponding to 9 and 10)
I will describe. As shown in FIG. 6, in this embodiment as well, the main body 41 of the dishwasher, which is a washing machine, is provided at the lower portion thereof with a projecting portion 42 projecting forward from the front surface of the door 16. The parts 42 are provided at the left and right ends of the main body 41. A front panel 43, which is a front plate located below the door 16, is provided on the front surface of the main body 41.
Is provided.

The projecting portion 42 projects further forward than the front panel 43. More specifically, FIG.
As shown in FIG. 3, the protrusion 42 is integrally provided on a bottom plate 44 that is made of a plastic molding and constitutes the outer bottom surface of the main body 41. In this case, each of the protrusions 42
Has a thin shape on the front end side (the upper surface is an inclined surface) and is formed in a hollow shape with an open bottom surface. However, as shown in FIG. 8, the rear surface (bottom portion) has a cylindrical shape on the front end side. The mounting boss portion 45 is integrally formed, and the mounting boss portion 45 is
A rubber leg 46 is fitted and fixed from the bottom side.
In addition, a plurality of reinforcing ribs 4 are provided on the back surface side of the protrusion 42.
7 are integrally formed, for example, extending radially from the periphery of the mounting boss portion 45, and the lower ends of the reinforcing ribs 47 are positioned so as to have a flat surface as a whole, so that an abutting portion described later is formed. Has been done.

Further, in this case, the leg portion 46 is a fixed leg whose height cannot be adjusted. As shown in FIGS. 6 and 7, for example, a rubber ring spacer 4 is used.
8 can be fitted and mounted around the leg portion 46.
The spacer 48 has a height dimension larger than a height dimension of a portion of the leg portion 46 projecting from the mounting boss portion 45. Therefore, as shown by an imaginary line in FIG. The height of the leg portion 46 (grounding portion) can be adjusted by fitting 48 into the abutting portion formed by the plurality of reinforcing ribs 47 until the abutting portion abuts.

According to this structure, as in the first embodiment, the leg portions 46 for supporting the main body 41 are provided on the lower surface of each protruding portion 42 protruding forward of the main body 41. Even when the tableware storage basket 14 is pulled out with 16 open, the main body 41 is stable and has an excellent effect of preventing forward fall, and at this time, the conventional auxiliary leg 5 and another fixing member are unnecessary. At the same time, the installation is simple, and it is possible to reliably prevent the occurrence of installation defects such as forgetting to attach the auxiliary leg 5.

Further, since the projecting portion 42 does not project forwardly as long as the conventional auxiliary leg 5, it is effective for saving the installation space. Further, it is possible to prevent the main body 41 from being installed in a position with poor stability, but in this case, except for the left and right end portions of the front surface of the main body 41, the main body 41 is located behind the protruding portion 42. Since it can be in the retracted form, the retracted portion can be widely used.

Here, FIG. 9 shows a schematic plan view of the system kitchen together with the layout of the installation position of the main body 41 of the dishwasher. This system kitchen is configured by arranging a sink 50 having a so-called R-shaped corner, a cooking heater 51, and the like on a worktop 49 having a depth dimension of, for example, about 630 mm, and further, on the back side of the worktop 49, a depth is provided. A face-to-face counter 52 having a dimension of, for example, about 250 mm, or a depth dimension of, for example, 3
A bay window 53 of about 80 mm is provided. Main body 4 of this embodiment
1 has a width of 500 mm and a depth of 300 m, for example.
The projecting length of the projecting portion 42 is about 30 mm.

As can be understood from FIG. 9, the main body 41 is
It can be installed not only on the worktop 49 but away from the sink 50, but can also be installed on the position of the bay window 53. Further, even at the position of, that is, the narrow position on the right side of the sink 50 on the worktop 49 (width dimension is, for example, 250 mm), the left and right leg portions 42 on the front side are formed into the sink 50 by using the R shape.
By arranging so as to straddle over, it becomes possible to install it sideways. In this case, since the retracted portion of the main body 41 covers the sink 50, the sink 50 can be widely used and a large pot or the like can be easily taken out.
It is to be noted that the position on the counter 52 and the part of the leg portions 46 installed on the sink 50 are prevented in advance.

Further, in this embodiment, since the leg portion 46 provided on the lower surface of the protrusion 42 is a fixed leg whose height cannot be adjusted, a mechanism for height adjustment is incorporated in the protrusion 42. Since it is not necessary, the protrusion 42 can be made thin, and it can be kept out of the way of the user as much as possible. Moreover, since the height can be adjusted by fitting the ring-shaped spacer 48 around the leg portion 46 until it abuts on the abutting portion, the height can be adjusted with a simple structure, and the installation surface is poor in levelness. Even in A, the main body 41 can be installed while being kept horizontal.

In this case, even if the projecting portion 42 is made of synthetic resin, a flat abutting portion can be easily formed by the reinforcing rib 47, and a rubber plate is punched out in a ring shape as the spacer 48. The spacer 48 itself can be made relatively inexpensive, for example, by adopting a member. Furthermore, since the protrusion 42 is integrally provided on the bottom plate 44 that constitutes the outer bottom surface of the main body 41, the structure is cheaper and simpler than when a separate member is attached, and the strength of the protrusion 42 and the legs are reduced. The attachment strength of the portion 46 can be improved.

In this embodiment, the spacer 48
Although it is configured in a ring shape, it may be a cap shape,
Further, the bottom surface of the protruding portion 42 may be formed into a flat plate shape to serve as an abutting portion. Of course, the bottom plate 44 may be made of metal or the like.

FIG. 10 shows a sixth embodiment of the present invention. The difference from the fifth embodiment is that the outer surfaces of the two left and right protrusions 42 are formed integrally with the front panel 43. It is configured so as to be covered by the covered cover portion 54. According to this, the unevenness of the protruding portion 42 portion, the butting of parts, the groove, and the like are covered with the cover portion 54 so as not to appear in the appearance, and the appearance of the protruding portion 42 can be easily seen.
The same color as that of No. 3 can be obtained, the appearance can be improved, and the effects of not collecting dust and the like can be obtained. Furthermore, the protrusions 42 do not need to be colored, and the protrusions 42 can be made of a resin material or sheet metal containing a filler having excellent strength.

(4) Seventh Embodiment FIGS. 11 to 13 show a seventh embodiment of the present invention (corresponding to claims 11 to 14). In this embodiment, the main body 41 of the dishwasher having substantially the same structure as that of the fifth embodiment is provided with a fixture 61 having a substantially C-shape as a whole.
I am trying to fix it. Further, in this embodiment,
The main body 41 is designed to be installed on the installation surface via an auxiliary installation plate 62.

That is, as shown in FIG.
An engaging portion 63 is formed in a horizontally elongated slit shape in the lower central portion of the right side surface of the. In this case, the locking portion 63
It is provided so as to be located between the front and rear legs 46, 46 on the bottom of the main body 41. On the other hand, the auxiliary installation plate 62
13 has a rectangular plate shape slightly larger than the main body 41, and as shown in FIG. 13, has a peripheral wall portion 62a which descends downward from the outer peripheral portion thereof. The legs 46 at the four corners of the body 41 are placed on the upper surface of the auxiliary installation plate 62.

Further, in this embodiment, the auxiliary installation plate 62 is used.
At the position corresponding to the engaging portion 63 on the right side portion of the peripheral wall portion 62a, a concave portion 62b for engaging the fixing tool 61 is formed by cutting a part of the lower end portion thereof. There is. Furthermore, the auxiliary installation plate 62 has a sufficient weight to function as a weight for preventing the body 41 from falling.
