DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cleaning dishes.
The present invention relates to a leak receiving material for a dishwasher .

[0002]

2. Description of the Related Art Conventionally, there is a system in which a storage room having a front opening is provided in a sink, and a built-in dishwasher is installed in a storage state in the storage room. In such a system, when water leaks from the dishwasher in the storage room for some reason, the inside of the sink may be flooded.
In order to prevent such a situation, a shallow dish-shaped waterproof pan similar to the waterproof pan of the washing machine is laid under the dishwasher in the storage room. Even if some water leaks from the dishwasher, it is possible to prevent water from leaking into the sink by storing the water in the waterproof pan.

[0003] Further, since the built-in dishwasher is placed in a storage room, it is difficult to confirm the fact that water has leaked from outside. For this reason, when the water leak is severe, there is a possibility that the water leaks from the waterproof pan and the inside of the sink becomes flooded. In order to prevent such a situation, there is a waterproof pan in which water on the upper surface is caused to flow forward (see Japanese Patent Application Laid-Open No. 9-56659). In such a waterproof pan,
The front part is opened, and the water is allowed to flow out of the floor to the floor in front of the sink, so that the leaked water can be used to confirm a leak from the dishwasher.

[0004] These waterproof pans have been formed in a planar shape approximately the same size as a dishwasher.

[0005]

However, a waterproof pan having approximately the same size as a dishwasher in plan view is large in size and therefore expensive. Further, in order to manufacture such a large waterproof pan, a large-sized one is required for manufacturing equipment such as a mold, so that the manufacturing cost is also high in this respect.

In general, when water leaks inside the dishwasher, the leaked water accumulates inside the dishwasher and then overflows onto the waterproof pan. And
Since water leakage is confirmed by the water on the waterproof pan or on the floor surface as described above, it takes time to confirm the leakage. If you can know such a leak quickly,
It is preferable for appropriately treating a water leak.

It is an object of the present invention to solve the above-mentioned technical problems and to provide a suitable small-sized leak receiving member for a dishwasher, which can quickly confirm the fact of water leakage.

[0008]

In order to achieve the above object, a dishwasher according to the present invention is provided on a bottom portion of a housing.
A receiving surface for receiving water leakage generated in the
At the front side of the bottom surface and received by the receiving surface
Dishwasher with holes formed to allow drained water to flow out
The dishwasher when installing it in the accommodation space inside the sink.
Material for a dishwasher placed below a washing machine
In , receiving the water falling from the hole, the received water
An inclined surface flowing toward the front side and water flowing from the inclined surface
Along the front of the sink so that the
Hanging on the bottom of the dishwasher
Fits the front legs and positions the dishwasher
A hole near the bottom of the dishwasher
And the gap between the bottom of the sink
It is characterized by being arranged to extend .

According to this configuration, the following operations are provided.
That is, if water leaks in the dishwasher, the water leak is received by the receiving surface at the bottom. When water reaches the hole, it can quickly flow out of the machine through the hole. The holes are located in front of the dishwasher, so you can easily see the water flowing out from the front. Also, in the case of a built-in dishwasher that is installed in a state of being stored inside the sink, a water leakage receiving member that receives water is arranged below the hole in order to prevent the inside of the sink from being flooded. Is preferred. Since water passes only through the above-mentioned holes, the size of the leak receiving material does not need to be the same as the planar shape of the dishwasher, but can be reduced.

[0010]

[0011]

[0012]

[0013] Further, the legs of the dishwasher are fitted with the leak receiving material.
Simply by fitting into the hole, the hole of the dishwasher and the inclined surface of the water leakage receiving material can be easily positioned, so that even in the case of a small water leakage receiving material, it is possible to prevent water from being lost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a dishwasher according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view of a dishwasher according to an embodiment of the present invention, illustrating a state where the dishwasher is installed in a sink.
FIG. 2 is a sectional side view of a schematic configuration of the dishwasher installed in the sink of FIG. In each of the drawings, arrows indicating directions (front-back direction X, left-right direction Y) are shown as necessary.

The dishwasher 2 is of a built-in type and is installed in a sink 1 as shown in FIG. The sink 1 is provided with a sink 1b on a top surface thereof, and a storage room 1a as a storage space therein. The storage room 1a has a front opening, in which the dishwasher 2 is stored. As shown in FIG. 2, the dishwasher 2 is positioned on the bottom surface of the storage chamber 1a via a water leak receiving member 3 which also serves as a positioning member.

The dishwasher 2 has a washing room 20 for storing dishes and a washing mechanism 23 for injecting washing water into the washing room 20. The cleaning chamber 20 is formed in a hollow box shape, and has an opening defined on the front surface thereof. The opening is covered with an openable door 21. Cleaning room 2
Inside 0, a tableware basket 22 for holding tableware is arranged, and an arm 31 is provided below the tableware basket 22. Wash water is injected from the plurality of injection ports 31a of the arm 31.

The washing mechanism 23 includes the above-described arm 31 and a washing pump 33 for pumping water to the arm 31 through a pipe 32.
And a water supply mechanism 38 for supplying cleaning water into the cleaning chamber 20. The water supply mechanism 38 includes a pipe, a solenoid valve, and the like, and can supply cleaning water into the cleaning chamber 20 from a water supply facility (not shown) such as water supply. The bottom of the cleaning chamber 20 is formed in a container shape and can store cleaning water. The bottom of the cleaning chamber 20 is connected to a cleaning pump 33 via a pipe 34. When the cleaning pump 33 is operated, cleaning water is injected from the arm 31. The arm 31 is connected to the cleaning chamber 20.
The washing water is rotatably supported around a vertical axis, and the washing water is rotated by the reaction force of the washing water, and the washing water is supplied to the dish basket 2.
By spraying on the dishes in 2, the dishes can be washed evenly. Thereafter, the washing water returns to the bottom of the washing chamber 20. The cleaning is performed while the cleaning water circulates. After the washing, the washing water is drained through a drain pipe (not shown) connected to the bottom of the washing chamber 20 by driving a drain pump 36 provided on the way.

The drain pump 36 and the washing pump 33 constitute a pump unit and are driven by a motor 37. The operation of the cleaning pump 33 and the drainage pump 36 can be switched according to the rotation direction of the motor 37. In addition, the dishwasher 2 is provided with a heater 25 near the bottom surface in the washing room 20 to heat the water stored in the washing room 20 to make it hot water, and to make it easy to wash with hot water. In addition, the heater 25 heats the surrounding air, and the blower fan 26 provided at the rear of the cleaning chamber 20 circulates the air in the cleaning chamber 20, so that the dishes can be dried with warm air.

The dishwasher 2 has a housing having a bottom part 41. A cover 4 is provided above the bottom portion 41.
2 is mounted over the washing chamber 20. Normally, water is prevented from leaking onto the bottom surface portion 41. The bottom part 41 covers the lower part of the dishwasher 2 and the washing room 2
0 and the cleaning mechanism 23. Bottom part 41
Has a rectangular plate-shaped main portion 41a and an upright portion 41b rising from three peripheral edges on the left and right sides of the main portion 41a. Legs 43 are attached to four corners of the lower surface of the main body 41a.

FIG. 3 is a plan view of the bottom of the dishwasher of FIG. The upper surface of the main body portion 41a is provided with a projection 41c having a leg 43 attached thereto and formed one step higher at four corners, and a main body portion 41a.
and a concave portion 41d (a hatched portion in FIG. 3) as a receiving surface formed at a center of the upper surface and one step lower than the periphery. A hole 41f communicating the upper surface and the lower surface of the bottom surface portion 41 is provided at a front end portion in the concave portion 41d.

The concave portion 41d is formed at a position where water leakage from above is supposed such that a pipe is disposed above the concave portion 41d. The concave portion 41d can receive water leaked from each portion of the dishwasher 2 above the concave portion on the upper surface. In particular, since the concave portion 41d is formed one step lower than the surrounding portion, the water received on the upper surface can be reliably received without spreading.

The recess 41d has a water reservoir 41e formed one step lower. Water reservoir 41e
Functions as an escape hole for inserting the lower part of the pump unit. The recess 41d includes a horizontal surface, and water on the surface flows out of the machine only through the hole 41f. In particular, since the concave portion 41d is not provided with a hole-like member through which water can pass except the hole 41f, the water surely flows out of the machine through the hole 41f.

The hole 41f communicates the inside of the concave portion 41d on the upper surface of the bottom portion 41 with the lower surface of the bottom portion 41. Hole 4
2f are provided adjacent to each other. The hole 41
Although the number of f is not particularly limited, it is preferable to arrange them close to each other in order to reduce the size of the water leakage receiving member 3 as described later. The hole 41f is located at a predetermined position,
For example, the front position of the bottom portion 41, in particular, the dishwasher 2
Near the front end. The hole 41f is disposed at the center in the left-right direction when viewed from the front.

The hole 41f is open rearward on the upper surface on the entrance side. That is, the front side portion and the left and right side portions of the entrance of the hole 41f are surrounded by the members erected from the upper surface of the bottom portion 41. The front side above the hole 41f is also covered by a portion extending in the horizontal direction from the upper end of the erected member. As described above, since the entrance of the hole 41f is open rearward, the hole 41f is
The water flowing to f flows from back to front,
It is preferable to flow water toward the front at the outlet side of the hole 41f.

In the dishwasher 2, it is assumed that water leaks from each part of the washing room 20, the washing mechanism 23 and the like. The leaked water falls into the concave portion 41d on the bottom surface portion 41 and is received, or falls around the concave portion 41d and flows into the concave portion 41d to be collected. When the water collected in this way reaches the hole 41f, the water immediately flows out toward the front through the hole 41f below the bottom portion 41 outside the machine.

Further, the collected water may accumulate in the lowest water reservoir 41e. In this case, the water spreads throughout the concave portion 41d and eventually reaches the hole 41f,
It will flow out of the machine through the hole 41f. Thus, according to the dishwasher 2 of the present embodiment, the recess 41
Since the hole 41f for allowing water to flow out of d is located in front of the dishwasher 2, the water that has flowed out can be easily and promptly confirmed from the front.

Further, since the concave portion 41d is one step lower, the water in the concave portion 41d can be prevented from spreading to the peripheral portion. As a result, the water can surely reach the hole 41f. Therefore, a water leak can be confirmed more quickly. Further, since the horizontal surface of the concave portion 41d and the water reservoir portion 41e can retain water, it is possible to prevent water from flowing out of the machine just by dropping a small amount of water into the concave portion 41d. as a result,
At the time of normal use in which the water does not fall into the concave portion 41d, it is possible to prevent the water from flowing out of the dishwasher, and to immediately notify the water leakage by the water outflow when an abnormality in which a large amount of water falls occurs.

Incidentally, the water flowing out of the hole 41f is preferably received by a water leakage receiving material such as a waterproof pan, and the water leakage receiving material can prevent the water leaking out of the storage chamber 1a from being flooded. . For example, the following leak receiving material 3 is preferable. Next, the water leakage receiving member 3 will be described. FIG.
FIG. 3 is a sectional side view of a main part of the dishwasher and the leak receiving member of FIG. 2. FIG. 5 is a perspective view of the water leakage receiving member of FIG.

The water leakage receiving member 3 is a substantially L-shaped channel member, and includes a main plate portion 3c disposed horizontally and a main plate portion 3c.
c has a hanging portion 3b extending downward from one longitudinal side end. The leak receiving member 3 has an inclined surface 3a at the center of the main plate 3c. The main plate portion 3c is disposed to extend in the left-right direction in a narrow gap between the lower front portion of the bottom portion 41 of the dishwasher 2 and the bottom surface of the storage room 1a of the sink 1. The hanging part 3b is arranged along the lower edge of the front opening of the storage room 1a and the front of the sink 1 so as to cover these parts.

The inclined surface 3a is inclined so that the front part is lower than the rear part, and is disposed immediately below the hole 41f. The inclined surface 3a can receive the water falling from the hole 41f and flow the received water in a predetermined direction, for example, toward the front side. The hanging portion 3b is connected at its upper end to the main plate portion 3c, and is connected to the inclined surface 3a. The hanging part 3b can guide water flowing down from the inclined surface 3a downward. At this time, it is difficult for water to enter the gap between the water leak receiving member 3 and the bottom surface of the storage room 1a of the sink 1, and it is possible to prevent the sink 1 from being wet or damaged by the water that has entered the gap.

The hanging part 3b is located along the lower edge of the front opening of the storage room 1a, so that the water leakage receiving member 3 can be easily positioned with respect to the front opening of the storage room 1a. Further, the water leakage receiving member 3 also functions as a positioning member for positioning the dishwasher 2 on the bottom surface of the storage room 1a of the sink 1. That is, the water leakage receiving member 3 has two elongated holes 3d as positioning portions for the dishwasher 2 and screw insertion holes 3e as a fixing structure, together with the hanging portion 3b positioned as described above. are doing. The water leakage receiving member 3 can be screwed to the bottom surface of the storage chamber 1a by a bolt inserted through the insertion hole 3e.

The elongated hole 3d is formed in the main plate portion 3c so as to be long in the left-right direction when viewed from the front. By fitting the two legs 43 on the front side of the dishwasher 2 into the long holes 3d, the dishwasher 2 is positioned so as to be adjustable in the left-right direction with respect to the water leakage receiving member 3 in the front-rear direction. be able to. In addition, the long hole may be formed long in the front and back so that the positioning between the dishwasher 2 and the water leakage receiving material 3 can be adjusted in the front and rear direction so that the position of the hole 41f and the inclined surface 3a does not shift. It suffices if there is a fitting hole into which the leg 43 is fitted.

According to the water leakage receiving member 3, as shown by the arrow in FIG. 4, the water from the hole 41f falls on the inclined surface 3a. The water quickly flows along the inclined surface 3a, flows down along the hanging portion 3b, and flows down to the floor in front of the sink 1. Thus, the user can easily confirm that water leaks into the dishwasher 2 due to the water flowing down on the floor. Therefore, it is possible to quickly take measures against the water leak, and as a result, it is possible to prevent the inside of the sink and the kitchen from being flooded. The floor surface in front of the sink 1 is usually made of a rinsing material, so that water flowing down on the floor surface can be easily wiped off.

As described above, according to the water leakage receiving material 3 of the present embodiment, since only the water from the hole 41f is received, it is not necessary to make the size of the water leakage receiving material 3 the same as the planar shape of the dishwasher 2. And can be made smaller. As a result, the water leak receiving member 3 can be manufactured at low cost. Further, since the hole 41f of the dishwasher 2 is located on the front side, the height of the water leakage receiving material 3 laid under the dishwasher 2 can be suppressed, and the slope of the inclined surface 3a can be made tight, so that water can be quickly drained. Can be flushed.

Further, since the hole 41f of the dishwasher 2 and the inclined surface 3a of the water leakage receiving material 3 can be easily positioned by the long holes 3d, even if the water leakage receiving material 3 is small,
It is possible to prevent the water from the hole 41f from being missed by the inclined surface 3a. Therefore, the inside of the sink 1 can be prevented from getting wet. In particular, the water leakage receiving member 3 and the dishwasher 2 can be easily positioned only by fitting the leg 43 into the long hole 3d.

Further, since the leak receiving member 3 also serves as a positioning member for attaching the dishwasher 2 to the sink 1,
The structure can be simplified. Moreover, when the dishwasher 2 is installed on the sink 1, positioning of the hole 41f and the inclined surface 3a can be completed at the same time, so that the dishwasher 2 can be easily attached. The washing mechanism 23 of the dishwasher 2 described above.
Is not particularly limited. In short, the dishwasher 2 only needs to have a washing mechanism for washing with water, and a bottom portion below the washing mechanism.

In the above-described embodiment, the built-in type dishwasher has been described. May be applied. In addition, various design changes can be made without changing the gist of the present invention.

[0040]

According to the present invention , the following effects can be obtained.
In other words, should a leak occur in the dishwasher, the water can be drained out of the machine through the holes located in front of the dishwasher. it can. In addition, the size of the leak receiving material for the built-in dishwasher can be reduced and the cost can be reduced.

[0041]

Further, the legs of the dishwasher are fitted with the leak receiving material.
Just by fitting into the hole, tilt the hole of the dishwasher and the leak receiving material.
Since it can be easily positioned on the slope, a small leak receiving material
In this case, it is possible to prevent water from being missed.
