Is communicated to.

As shown in FIG. 15, a rectangular through hole 81 (entering portion) is formed in the bottom plate 4A corresponding to the lower side of the cleaning pump 56. The size of the through hole 81 is such that the lower part of the pump casing 56C of the washing pump 56 can enter, and for example, is always inserted by a detachable lid plate 82 inserted from the front and engaged and fixed to the upper surface of the bottom plate 4A. Are coated.

Tap water is introduced into the booster tank 66 from a pipe (not shown), and rinsing water (hot water) of a predetermined temperature is stored by a heater (not shown). The sides are in communication. The discharge side of the rinsing pump 67 is connected to the upper and lower rinsing nozzles 13 and 14 via a passage (not shown) in the pipe 70.

The booster tank 66 is mounted on the bottom plate 4A at the right end in the machine room 4, and the bottom plate 2D immediately above the booster tank 66 is inclined to the right and high (indicated by P in FIG. 2). . Thereby, the opening frontage of the cleaning room 3 is expanded in the vertical direction, and even if the height of the machine room 4 is compressed, the booster tank 66 having a predetermined capacity can be installed without any trouble. With the above configuration, the frontage dimension of the cleaning chamber 3 can be secured to about 310 mm in the vertical direction.

At the four corners of the bottom plate 4A, there are pedestals 69.
Is attached. The height of the foot 69 is 80
mm, thereby ensuring cleaning workability under the bottom plate 4A. Further, the front of the machine room 4 is closed by a machine room panel 71 that can be opened and closed.

On the other hand, the cleaning pump 56 is disposed on the left side of the machine room 4 and immediately before the cleaning tank 9, and the lower surface of the pump casing 56C is located immediately above the cover plate 82 of the bottom plate 4A in the assembled state. I have. The electrical box 68 is arranged in the machine room 4 immediately before the motor 56M of the cleaning pump 56. The electrical component box 68 has an opening at the front side, in which a relay and a terminal plate (not shown) are stored.
A plurality of through holes 73 are formed in 8A.

Further, a duct member 74 having a U-shaped cross section is attached to the rear surface of the back wall 68A.
A vertical passageway 76 that opens vertically is formed in the inside 4, and the through holes 73 communicate with the ventilation passage 76. The rear surface of the duct member 74, that is, the motor 5
A heat insulating material 77 is attached to the surface on the 6M side.

The electrical component box 68 is floated above the bottom plate 4A at a slight distance from the main body (the exterior plate 8, the angle member 6).
Alternatively, a plurality of ventilation holes 7 are provided in the bottom plate 4A below the electrical equipment box 68.
8 ... are drilled.

When the power is supplied to the dishwasher 1 with the above configuration, first, the rinse pump 67 is operated, and the rinse water (hot water) stored in the booster tank 66 is injected from the vertical rinse nozzles 13 and 14. . The injected rinse water drops on the bottom plate 4D, flows into the cleaning tank 9 soon, and is stored as the cleaning water. The washing tank 9
Also, a heater (not shown) is provided, the washing water is kept at a predetermined temperature, and the detergent is injected by a pipe (not shown).

[0049] The hot water supply operation is completed and a standby state is established.
Next, the rack on which the tableware as the object to be washed is placed is inserted along the rack rail 53 and stored in the washing room 3. Then, when a predetermined start switch is operated, the cleaning process is started. In this cleaning step, the cleaning pump 56 is operated, and the cleaning water stored in the cleaning tank 9 is jetted from the upper and lower cleaning nozzles 11 and 12 toward the dishes. As a result, the dishes are cleaned. The injected cleaning water is dropped on the bottom plate 2D, collected in the cleaning tank 9, and reused.

This cleaning step is performed for a predetermined period, and then the procedure shifts to a rinsing step. In this rinsing stroke, the rinsing pump 67 is operated as described above, and the upper and lower rinsing nozzles 13,
From 14 rinsing water in the booster tank 66 is sprayed toward the dishes. Thus, the washing water attached to the tableware is rinsed, and the rinsing water flows into the washing tank 9 in the same manner.

Here, as described above, the booster tank 66
Since the upper bottom plate 2D is higher to the right, that is, inclined lower in the direction of the washing tank 9, the washing water and the rinsing water dropped on the bottom plate 2D smoothly move toward the washing tank 9 (the left direction in FIG. 2).
To flow to. The water level in the washing tank 9 rises due to the inflow of the rinsing water, but flows out of the overflow pipe 54 when it becomes higher than the overflow pipe 54, so that the water level W is regulated at the upper end of the overflow pipe 54.

Although the washing water contains dirt and debris dropped from tableware, a cover 63 is located around the overflow pipe 54, and the upper surface 63A and the peripheral side surface 63A thereof.
.. Are prevented from entering the overflow pipe 54.

In particular, as described above, the upper surface 63A of the cover 63
And through holes 64 at the corners of the peripheral side surfaces 63B
Since the holes are formed, it is possible to prevent the through hole 64 from being submerged under the water surface W while securing the opening area of the through hole 64. As a result, air can be reliably removed from the overflow pipe 54.

The washing water and the rinsing water sprayed from the nozzles 11, 12, 13, and 14 adhere to the top plate 2A as water droplets. Moves smoothly toward the front opening without stagnation. Then, it flows into the gutter portion 41B of the catcher fixing plate 41, flows down right and left, and finally flows down along the side plate 2C of the inner box 2. In addition, water droplets attached to the packing 42 also flow down the left and right along the inclination of the lower surface.
This prevents so-called drooping of washing water dripping from the top plate 2A onto the tableware after rinsing.

When the cleaning pump 56 is operated, heat is generated from the motor 56M.
Since the heat insulating material 77 and the ventilation path 76 are interposed between the motor 56M and the motor 56M, such heat generation is shut off, and the heat is hardly transmitted to the electrical box 68. Further, the relays and the like in the electrical box 68 also generate heat, but the electrical box 68 floats from the bottom plate 4A, and the ventilation holes 78 are formed thereunder. The outside air enters the ventilation passage 76, flows into the electrical equipment box 68 through the lower through-hole 73, circulates, and then passes through the upper through-hole 73 again to the ventilation passage 7.
Then, it flows out to 6 and is exhausted.

As a result, the temperature rise in the electrical component box 68 can be kept low, and failures of components such as relays can be avoided or suppressed beforehand, and a longer life can be achieved.

When the cleaning pump 56 is taken out of the machine room 4 when the cleaning pump 56 breaks down, the machine room panel 71 and the electrical box 68 are first removed, and then the cover plate 82 is pulled forward. And remove it from the bottom plate 4A. Thereby, the through hole 81 is opened.

Next, the screws fixing the discharge side 56D and the suction side 56S of the pump casing 56C of the cleaning pump 56 to the bottom plate 2D and the cleaning tank 9 are removed. In this state, as shown by the arrow in FIG.
6 is pulled downward, and the closely contacting discharge side 56D and suction side 56S are removed from the bottom surface 2D or the cleaning tank 9. At this time, the lower part of the pump casing 56C has the through hole 8
1 (FIG. 16).

Thereafter, the cleaning pump 56 is pulled out while slightly lifting it up. Conversely, when assembling the cleaning pump 56, the opposite operation is performed. As described above, in the present invention, the through-hole 81 is formed in the bottom plate 4A below the cleaning pump 56 so that the pump casing 56C of the cleaning pump 56 can be dropped into the through-hole 81. The vertical dimension of the machine room 4 is designed and set so that the casing 56C is located immediately above the bottom plate 4A.
Since the pump casing 56C of the washing pump 56 can be once dropped into the inside to perform the work, even if the height of the machine room 4 is reduced to save the space of the dishwasher 1, there is no problem. The cleaning pump 56 can be attached and detached.

In particular, since it is constituted by the through-hole 81 formed in the bottom plate 4A of the machine room 4 and the cover plate 82 covering the through-hole 81, the structure is simplified, the cost is reduced and the cleaning pump 56 is reduced.
Can be improved.

In the embodiment, the entry portion is constituted by the through hole 81, but the invention is not limited to this, and the bottom plate 4A may be recessed downward.

[0062]

As described above in detail, according to the present invention, the cleaning pump is mounted on the machine room bottom plate of the cleaning machine corresponding to the lower portion of the cleaning pump because the cleaning pump can enter the cleaning chamber. Design and set the vertical dimensions of the machine room with
When attaching and detaching the cleaning pump, it is possible to drop the cleaning pump into the entrance and perform the operation.

Therefore, even if the height of the machine room is reduced to save the space of the washing machine, the washing pump can be attached and detached without any trouble.

According to the second aspect of the present invention, the entrance portion is constituted by a through-hole formed in the bottom plate of the machine room, and the through-hole is covered by a detachable lid plate. This makes it possible to reduce the cost and improve the workability of attaching and detaching the cleaning pump.
